To the stockholders of Bruker BioSciences Corporation:

On behalf of the board of directors and management of Bruker BioSciences Corporation, I would like to invite you to attend our Special Meeting of Stockholders to be held on [Wednesday, January 30], 2008 at 9:00 a.m., local time, at the offices of Nixon Peabody LLP, 100 Summer Street, Boston, Massachusetts.

At this important meeting you will be asked to consider and vote on proposals to, among other things, approve three transactions that will result in the combination of Bruker BioSciences with the Bruker BioSpin group of companies, including Bruker BioSpin Inc., Bruker BioSpin Invest AG, Techneon AG and Bruker Physik GmbH and each of their respective direct and indirect wholly owned subsidiaries, which we sometimes collectively refer to as the "Bruker BioSpin Group."

Upon completion of the proposed transactions, the shareholders of the Bruker BioSpin Group will receive approximately $388 million in cash and 57,544,872 shares of our common stock, which have a market value of approximately $703.8 million as of December 5, 2007. As of December 5, 2007, this represented approximately 35% of our post-transaction outstanding voting securities. The amount of 57,544,872 shares was based upon an agreed amount of $526 million of stock consideration and the trailing ten trading day average closing price of our common stock ending two trading days prior to the signing of the transaction agreements of $9.14 per share which, combined with the approximately $388 million of cash consideration, reflected a total purchase price for the Bruker BioSpin Group of $914 million.

The six Bruker BioSpin Group shareholders, comprised of me, Frank H. Laukien, and five other members of my family, who we refer to as the Bruker BioSpin Group Shareholders, are also major stockholders of Bruker BioSciences. Accordingly, the board of directors of Bruker BioSciences appointed a special committee consisting of independent directors unaffiliated with the Bruker BioSpin Group Shareholders for the purpose of considering the advisability of the combination, negotiating its terms on behalf of Bruker BioSciences and recommending to the board of directors of Bruker BioSciences whether the combination was in the best interests of the stockholders of Bruker BioSciences who are not affiliated with the Bruker BioSpin Group Shareholders.

The closing of the combination is contingent on stockholder approval of the transactions contemplated by each of the transaction agreements, including the issuance of shares of our common stock in connection with the transactions. Although not required under Delaware law, the rules of The NASDAQ Global Select Market require stockholder approval of the share issuance, which must, under our bylaws, be approved by the affirmative vote of the holders of a majority of the shares of Bruker BioSciences common stock present or represented by proxy at the Special Meeting and entitled to vote. Under the terms of each of the transaction agreements, the Bruker BioSpin Group Shareholders, who currently hold, in the aggregate, approximately 52% of the outstanding shares of Bruker BioSciences common stock, have covenanted that they will vote the shares of our stock that they own in favor of the transactions contemplated by the transaction agreements. In addition, under the terms of each of the transaction agreements, the transactions contemplated must also be approved by the holders of shares of Bruker BioSciences common stock who are unaffiliated with the Bruker BioSpin Group Shareholders and who represent at least a majority of the total votes cast by these unaffiliated holders at the Special Meeting.

Each of the proposals regarding the transaction agreements are conditioned on the approval of the other two proposals regarding the transaction agreements. After careful consideration, the board of directors has unanimously approved the terms and conditions of the transaction agreements and recommend that you vote "FOR" each of the transactions necessary to effect the combination of

Bruker BioSciences with the Bruker BioSpin Group and the related issuance of shares of Bruker BioSciences common stock.

In addition to the proposals relating to the transactions necessary to effect the combination with the Bruker BioSpin Group and the related issuance of shares, you will be asked to consider and vote upon the following proposals at the Special Meeting:

•: A proposal to amend the Bruker BioSciences certificate of incorporation to increase the number of shares of common stock authorized for issuance from 200,000,000 to 260,000,000.
•: A proposal to amend the Bruker BioSciences amended and restated stock option plan to increase the number of shares of common stock for which options and restricted stock may be granted under the stock option plan from 8,000,000 to 10,000,000.
•: A proposal to amend the Bruker BioSciences certificate of incorporation to change our name from Bruker BioSciences Corporation to Bruker Corporation.
•: A proposal to elect one Class II Director to hold office until the 2008 Annual Meeting of Stockholders and one Class III Director to hold office until the 2009 Annual Meeting of Stockholders.

The proposals regarding the charter amendments, the amendment to our stock option plan and the election of new directors are contingent on the approval of each of the transactions contemplated by the transaction agreements and the related issuance of shares of common stock as well as on the closing of the combination. The board of directors recommends that you vote "FOR" the proposals to amend our charter, the amendment of the stock option plan and the election of the two additional directors to serve on the board.

I look forward to your participation and thank you for your continued support.

		Sincerely,

		Frank H. Laukien, Ph.D. Chairman, President and Chief Executive Officer

SUMMARY TERM SHEET

The following is a summary of the proposed transactions among Bruker BioSciences Corporation and Bruker BioSpin Inc., Bruker BioSpin Invest AG, Bruker Physik GmbH and Techneon AG (which we sometimes refer to collectively as the Bruker BioSpin Group), in which Bruker BioSciences proposes to acquire all of the capital stock of the companies comprising the Bruker BioSpin Group. The transactions contemplated will constitute a business combination of companies under common control as the five largest Bruker BioSciences stockholders, Frank H. Laukien, President, Chief Executive Officer and Chairman of the board of directors of Bruker BioSciences, Dirk D. Laukien, Senior Vice President of Bruker BioSciences and President of its subsidiary Bruker Optics Inc., Joerg Laukien, a director of Bruker BioSciences, Marc Laukien and Isolde Laukien-Kleiner, who are all related as family members, are also, together with Robyn Laukien, the shareholders of each of the companies within the Bruker BioSpin Group. Bruker BioSciences is seeking stockholder approval of the transactions necessary to effect the combination and the issuance of Bruker BioSciences common stock to the Bruker BioSpin Group shareholders.

This term sheet is a summary and does not contain all of the information that may be important to you. You should carefully read this entire document, including the appendices and the other documents to which this document refers you, for a more complete understanding of the matters relating to the transactions and the issuance of Bruker BioSciences common stock. See "Where You Can Find More Information" beginning on page [142].

On December 2, 2007 Bruker BioSciences entered into definitive agreements with each of the companies of the Bruker BioSpin Group, which we refer to collectively as the transaction agreements, to acquire all of the equity of each of the Bruker BioSpin Group companies. In connection with the proposed transactions and business combination:

•: Bruker BioSciences, under the terms of the U.S. stock purchase agreement, will acquire 100% of the common stock of Bruker BioSpin Inc., a Delaware corporation.
•: Bruker BioSciences, under the terms of the German share purchase agreement, will acquire, directly and indirectly, 100% of the share capital of each of Bruker Physik GmbH, a German limited liability company, and Techneon AG, a Swiss stock corporation.
•: Bruker BioSciences, under the terms of the Swiss merger agreement, will acquire through various of its indirect subsidiaries via merger the equity interest of Bruker BioSpin Invest AG, a corporation organized under the laws of Switzerland.
•: Upon completion of the transactions, the companies of the Bruker BioSpin Group will become wholly owned subsidiaries of our company.
•: The aggregate total purchase price payable by Bruker BioSciences to the holders of all of the equity of the Bruker BioSpin Group is payable in cash and stock.
•: This consideration will be paid to the shareholders of the Bruker BioSpin Group approximately pro rata in accordance with their respective ownership of the shares of each of the Bruker BioSpin Group companies.
•: There will be a cash payment to the shareholders of the Bruker BioSpin Group of $388 million.
•: Bruker BioSciences expects to issue 57,544,872 restricted shares of its common stock, which have a market value as of December 5, 2007 of $703.8 million, to the shareholders of the Bruker BioSpin Group as the stock portion of the aggregate purchase price. The amount of 57,544,872 shares was based upon an agreed amount of $526 million of stock consideration and the trailing ten trading day average closing price of our common stock ending two trading days prior to the signing of the transaction agreements of $9.14 per share which, combined with the approximately

$388 million of cash consideration, reflected a total purchase price for the Bruker BioSpin Group of $914 million.

•: As permitted by the transaction agreements, prior to the closing of the transactions and independent of the transactions, the Bruker BioSpin Group will pay the Bruker BioSpin Group Shareholders a dividend of 75 million Swiss Francs (approximately $66.7 million based on the exchange rate of 0.88 U.S. Dollars per Swiss Franc on December 5, 2007) out of accumulated retained earnings of Bruker BioSpin Invest AG. This pre-closing dividend by the Bruker BioSpin Group is not part of the purchase price for the transactions.
•: Bruker BioSciences and some of its foreign subsidiaries expect to enter into credit agreements with a syndicate of lenders to finance a portion of the cash consideration to be paid to the shareholders of the companies comprising the Bruker BioSpin Group. The aggregate $380 million principal amount credit facilities, of which we expect to draw down approximately $351 million, will consist of a $230 million five-year revolving credit facility and a $150 million five-year term loan facility. Bruker BioSciences has executed commitments from J.P. Morgan Securities Inc. and Citibank, N.A. for the entire $380 million principal amount of the new credit facilities. The proceeds of the facilities will be used to finance a portion of the cash portion of the combination and to provide working capital and funds for general corporate purposes, including permitted future acquisitions, if any. The credit facilities will be secured by pledges of 100% of the equity interests in our domestic subsidiaries and 65% of the equity interests in our material foreign subsidiaries.
•: The transaction agreements prohibit the sale of the Bruker BioSciences shares issued as part of the purchase price for a period of one year after the closing date, except for certain permitted transfers of stock from one Bruker BioSpin Group Shareholder to another.
•: The shareholders of the companies comprising Bruker BioSpin Group, including our president and chief executive officer Frank H. Laukien, senior vice president Dirk Laukien, and Director Joerg Laukien, currently hold, in the aggregate, approximately 52% of the outstanding shares of Bruker BioSciences common stock, and, immediately following the consummation of the transactions if the closing date was December 5, 2007, would hold approximately 69% of the outstanding shares of Bruker BioSciences common stock.
•: The six shareholders of the Bruker BioSpin Group will be subject to five year non-competition and non-solicitation covenants which are described in each of the transaction agreements.
•: $92 million of the cash purchase price will be held in escrow following the closing of the transactions to satisfy any indemnification claims asserted by Bruker BioSciences within a designated time period.
•: An additional $6.75 million of the cash purchase price will be held in escrow following the closing of the transactions to satisfy any post-closing adjustments to the purchase consideration which may result if the working capital of the Bruker BioSpin Group is less than $180 million on December 31, 2007.
•: Upon completion of the combination, Frank H. Laukien and Dirk D. Laukien will serve as co-chief executive officers of our Bruker BioSpin operations. Joerg Laukien will serve as the European chief operating officer of our Bruker BioSpin subsidiary.

QUESTIONS AND ANSWERS ABOUT THE COMBINATION

Q:: Why is Bruker BioSciences proposing the transactions and the combination?
A:: We are proposing to enter into the transactions and to combine with the companies of the Bruker BioSpin Group because we believe that the Bruker BioSpin Group business complements the

business of our three existing direct operating subsidiaries, Bruker AXS, Bruker Daltonics and Bruker Optics. We expect that adding the products of the Bruker BioSpin Group will increase our sales opportunities and increase our presence in various markets, providing Bruker BioSciences with an extra competitive edge as we become a more broadly based company.

Q:: How much is Bruker BioSciences paying for the companies comprising the Bruker BioSpin Group?
A:: Bruker BioSciences has agreed to pay the shareholders of the Bruker BioSpin Group $388 million in cash and 57,544,872 Bruker BioSciences shares, which as of December 5, 2007 have a market value of approximately $703.8 million, for all of the outstanding shares of the Bruker BioSpin Group companies. The amount of 57,544,872 shares was based upon an agreed amount of $526 million of stock consideration and the trailing ten trading day average closing price of our common stock ending two trading days prior to the signing of the transaction agreements of $9.14 per share which, combined with the approximately $388 million of cash consideration, reflected a total purchase price for the Bruker BioSpin Group of $914 million.
Q:: How will Bruker BioSciences pay for the shares of Bruker BioSpin Group?
A:: Bruker BioSciences will purchase the Bruker BioSpin Group companies' stock using a combination of cash and newly issued shares of Bruker BioSciences common stock. Bruker BioSciences will finance the cash component of the combination consideration from its available cash and with borrowings under new credit facilities to be entered into in connection with the combination. The new credit facilities are expected to have an aggregate borrowing capacity of $380 million, which, together with available cash, will be available for the following purposes: (1) to finance approximately $388 million of cash consideration to be paid to shareholders of the Bruker BioSpin Group companies; (2) to finance expenses of the combination; (3) to provide working capital; and (4) for general corporate purposes, including the financing of any future acquisitions, if any.
Q:: What will happen to my shares of Bruker BioSciences common stock in the combination?
A:: The shares of Bruker BioSciences common stock that you hold will not change as a result of the combination. However, you should be aware that the issuance of shares of our common stock to the shareholders of the Bruker BioSpin Group will cause a reduction in the relative percentage interests of current Bruker BioSciences stockholders in earnings, voting, liquidation value and book value.
Q:: What am I voting on in connection with the combination and why?
A:: You are voting to approve Bruker BioSciences' combination with the Bruker BioSpin Group companies as well as the issuance of the shares of our common stock which will be used a part of the consideration for the acquisition.

To consummate the combination, you are being asked to vote on the following items necessary to effectuate the transaction:

•: A proposal to purchase Bruker BioSpin Inc. (Proposal 1);
•: A proposal to purchase Bruker Physik and Techneon (Proposal 2);
•: A proposal to approve Bruker BioSciences' acquisition, via merger, of the equity interests of Bruker BioSpin Invest AG and the related issuance of shares (Proposal 3). You are asked to vote on the related issuance of shares to consummate this transaction because our common stock is quoted on the NASDAQ Global Select Market. NASDAQ Marketplace Rule 4350(i)(1)(C)(i) requires stockholder approval of the issuance of common stock in connection with the acquisition because various of our officers and directors have greater than a 5% equity interest in each of the Bruker BioSpin Group companies, and the shares of our

common stock issued in connection with the acquisition will result in a greater than 5% increase in Bruker BioSciences outstanding common stock and voting power;

•: A proposal to approve a charter amendment to increase the number of authorized shares that may be issued by the company from 200,000,000 to 260,000,000 (Proposal 4);
•: A proposal to approve an amendment to the Bruker BioSciences amended and restated stock option plan to increase the number of shares of common stock for which options may be granted from 8,000,000 to 10,000,000 (Proposal 5);
•: A proposal to approve a charter amendment to change to our name from Bruker BioSciences Corporation to Bruker Corporation (Proposal 6); and
•: A proposal to approve the election of one Class II Director to hold office until the 2008 Annual Meeting of Stockholders and one Class III Director to hold office until the 2009 Annual Meeting of Stockholders (Proposal 7).

The board of directors recommends that you vote "FOR" each of the proposals set forth above.

Q:: What stockholder approvals are needed in connection with the combination?
A:: The affirmative vote of the holders of a majority of the outstanding shares of Bruker BioSciences common stock present or represented by proxy and entitled to vote at the Special Meeting is required to approve the transactions contemplated by the transaction agreements, including the issuance of shares of Bruker BioSciences common stock to be used as part of the consideration. Each holder of common stock is entitled to one vote per share. As of the record date, Bruker BioSciences directors and executive officers and their affiliates owned [37.9]% of the outstanding shares. The five largest stockholders of Bruker BioSciences, including Frank H. Laukien, are also five of the six shareholders of the companies of the Bruker BioSpin Group and are parties to the transaction agreements. These six shareholders have covenanted in the transaction agreements that they will vote in favor of the acquisition. The shares held by these six shareholders represent approximately 52% of the voting power of Bruker BioSciences capital stock entitled to vote at the stockholder meeting, and are sufficient, under our bylaws and NASDAQ rules, to approve the transactions contemplated by the transaction agreements, including the share issuance.

The terms of the transaction agreements also provide that the transactions contemplated by the stock purchase and merger agreements are subject to approval by holders of shares of Bruker BioSciences common stock who are unaffiliated with the Bruker BioSpin Group Shareholders, and who represent at least a majority of the total votes cast by these unaffiliated holders at the Special Meeting.

Q:: What stockholder approvals are required to approve the charter amendments and the amendment to our stock option plan?
A:: The affirmative vote of the holders of a majority of the shares of Bruker BioSciences common stock outstanding as of the record date is required to adopt and approve (i) the amendment to the certificate of incorporation to increase the number of shares of common stock authorized for issuance from 200,000,000 to 260,000,000 and (ii) the amendment to the certificate of incorporation to change our name to Bruker Corporation.

The affirmative vote of a majority of our shares present or represented at the Special Meeting is required to approve the amendment to our stock option plan to increase the number of shares of common stock for which options and restricted stock may be granted under the stock option plan from 8,000,000 to 10,000,000.

Q:: What stockholder approvals are required to elect the new directors to the board?
A:: Our directors are elected by a plurality of the shares of common stock present in person or represented by proxy at the Special Meeting and entitled to vote. This means that the two candidates for election as directors at the Special Meeting who receive the highest number of affirmative votes will be elected.

The Bruker BioSpin Group (see page [90])

The companies of the Bruker BioSpin Group develop, manufacture and distribute life science analytical instrumentation and solutions based on magnetic resonance core technology. The companies' products include tools developed for nuclear magnetic resonance, or NMR, electron paramagnetic resonance, or EPR, magnetic resonance imaging, or MRI. The Bruker BioSpin Group also designs and develops superconducting wire materials that can be used in a variety of applications including power

cables, motors, generators and superconducting magnets. Products and solutions developed by the Bruker BioSpin Group are utilized in a wide variety of applications, including:

•: life science applications including the structure and function determination of large biomolecules such as proteins and membrane proteins;
•: pharmaceutical and biotech research and manufacturing to identify new compounds, observe the interaction of drugs with a target protein, study the toxicology of drug candidates and identify properties of the final product;
•: metabolic profiling and fingerprinting, where patterns can be evaluated using spectroscopic techniques combined with multivariate statistical methods to gain insight into the response of a biological system to perturbations in a time-related manner;
•: non-invasive magnetic resonance imaging aimed at detecting the origins of disease related pathways and targets by combining the use of molecular biomarkers;
•: structure determination and elucidation for application in organic and inorganic synthesis;
•: materials research for the design and characterization of materials such as polymers, catalysts, fuel cell materials, etc.;
•: food, beverage and agricultural analysis for the monitoring of the production and distribution cycle of products to ensure their origin, authenticity, safety and reliability; and
•: superconducting magnets for use in magnetic resonance, imaging and physics experiments.

Magnetic resonance is the core technology of the Bruker BioSpin Group. Magnetic resonance is a natural phenomenom occurring when a molecule, placed in a magnetic field, gives off a radio frequency signature. The signature is characteristic of the particular molecule and this leads to a multitude of precise chemical and structural information. A typical magnetic resonance instrument includes a radio frequency source and transmitter, one or more very sensitive detectors, a magnet sized for the particular application and operating and analysis software.

When magnetic resonance is used to analyze the resonance effect of various atoms, it is known as NMR. NMR is a widely used analytical technique by academia, pharmaceutical and biotechnology companies and other industrial users in life sciences and materials science research.

When an image is reconstructed by localizing the origin of the NMR signal, this is known as MRI. The Bruker BioSpin Group's MRI products focus on pre-clinical applications, mainly research on small animals for disease studies and drug discovery by pharmaceutical companies and academia.

When the magnetic resonance signals arise from the electrons contained in a molecule, this is known as EPR. EPR is used mainly in academia for research purposes. All three magnetic resonance techniques employ strong magnetic fields which are typically reached through the use of superconducting magnets. The Bruker BioSpin Group is a leader in superconducting magnet technology and also owns a developer and manufacturer of the specialty superconducting wires needed for magnetic resonance magnets.

The Bruker BioSpin Group's magnetic resonance product line is complimented with a number of accessories. These accessories include a wide array of sample handling devices for automation and high throughput applications, as well as advanced data management and analysis software. These accessories permit the Bruker BioSpin Group to tailor its products for specific customers.

In addition to these magnetic resonance instruments, the Bruker BioSpin Group also manufactures bench-top instruments for process control, quality assurance and quality control applications. The Bruker BioSpin Group typically sells these bench-top instruments to the pharmaceutical industry, the food industry and other industrial customers.

The Bruker BioSpin Group includes research and manufacturing facilities in Germany, Switzerland, France and the U.S., as well as numerous sales, applications and service offices throughout the U.S., Europe, Asia and South America. The Bruker BioSpin Group employs approximately 1,850 people throughout the world.

STRUCTURE OF THE TRANSACTIONS AND OPERATIONS AFTER THE COMBINATION

Bruker BioSciences is acquiring all of the outstanding stock of the companies comprising the Bruker BioSpin Group in three transactions through which Bruker BioSciences will: (1) acquire all of the common stock of Bruker BioSpin Inc., (2) acquire all of the share capital of Bruker Physik and Techneon, and (3) acquire the equity of Bruker BioSpin Invest AG through a reverse triangular merger. Following the completion of these transactions, we intend to operate the Bruker BioSpin Group companies as wholly owned subsidiaries alongside Bruker AXS, Bruker Daltonics and Bruker Optics.

PURCHASE PRICE (see pages 49, 59 and 68)

The aggregate total purchase price payable by Bruker BioSciences for the stock of the companies of the Bruker BioSpin Group in the three transactions is $388 million payable in cash and 57,544,872 shares of Bruker BioSciences stock which, as of December 5, 2007, have a market value of approximately $703.8 million. The amount of 57,544,872 shares was based upon an agreed amount of $526 million of stock consideration and the trailing ten trading day average closing price of our common stock ending two trading days prior to the signing of the transaction agreements of $9.14 per

share which, combined with the approximately $388 million of cash consideration, reflected a total purchase price for the Bruker BioSpin Group of $914 million.

This consideration will be paid to the shareholders of the Bruker BioSpin Group approximately pro rata in accordance with their respective ownership of the shares of each of the Bruker BioSpin Group companies. As described in more detail later in this proxy statement, the transaction agreements prohibit the sale of the Bruker BioSciences shares issued as part of the combined purchase price for a period of one year after the closing date, except for various permitted transfers of stock from one Bruker BioSpin Group Shareholder to another, under cash-share exchange agreements entered into among the Bruker BioSpin Group Shareholders in order to allow them to achieve their desired individual cash and share percentage elections from the aggregate proceeds of the three transactions. Bruker BioSciences will finance the cash component of the combination consideration from its available cash and with borrowings under new credit facilities to be entered into in connection with the combination. The new credit facilities are more fully described in this proxy statement. See "Source of Funds" on page [43].

This approval is guaranteed since the Bruker BioSpin Group Shareholders, who own in the aggregate approximately 52% of the outstanding Bruker BioSciences common stock as of December 5, 2007, have agreed in each of the transaction agreements to vote to approve all of these transactions.

The completion of the transactions contemplated by the transaction agreements is also subject to the satisfaction or waiver of other conditions, including, among others, the expiration or termination of applicable waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended. See "Conditions to the Acquisition" on pages [54, 64, and 74].

TERMINATION OF THE TRANSACTION AGREEMENTS (see pages [57, 67 and 78])

The transaction agreements may be terminated at any time prior to closing by the mutual written consent of Bruker BioSciences and the sellers. In addition, either Bruker BioSciences or the applicable sellers may terminate the U.S. stock purchase agreement, the German share purchase agreement and the Swiss merger agreement at any time prior to closing if:

•: any governmental entity shall have issued an order permanently restraining, enjoining, or otherwise prohibiting the completion of the transactions and such order is final and nonappealable;
•: we do not receive stockholder approval for the transactions;
•: either the U.S. stock purchase agreement, the German share purchase agreement or the Swiss merger agreement is terminated; or

Bruker BioSciences may terminate each of the agreements at any time prior to closing if the sellers or Bruker BioSpin Inc., Bruker Invest, Techneon or Bruker Physik breach any of their respective

covenants, representations and warranties, or other agreements contained in the agreements and the breach would give rise to the failure of a condition to Bruker BioSciences' obligation to complete the acquisition and the breach is not curable or, if curable, is not cured or waived within 20 calendar days after written notice of the breach has been delivered to the breaching party.

The applicable sellers may terminate the agreements at any time prior to closing if Bruker BioSciences breaches any of its covenants, representations and warranties, or other agreements contained in the agreements and the breach would give rise to the failure of a condition to the sellers' obligation to complete the acquisition and the breach is not curable or, if curable, is not cured or waived within 20 calendar days after written notice of the breach has been delivered to Bruker BioSciences.

EXPENSES (see pages [58, 67 and 78])

The transaction agreements provide generally that regardless of whether the combination is consummated, all fees and expenses incurred by the parties will be paid by the party incurring such fees and expenses. With respect to fees due in connection with filings made pursuant to the Hart-Scott-Rodino Act, Bruker BioSciences shall be responsible for all fees relating to its own filing and the Bruker BioSpin Group shall be responsible for all fees relating to filings made by it or any of the selling shareholders.

The selling shareholders and the companies of the Bruker BioSpin Group are obligated to immediately disclose to Bruker BioSciences any such third party inquiries or proposals, including the terms thereof.

ACCOUNTING TREATMENT OF THE COMBINATION (see page [46])

The combination represents a business combination of companies under common control due to the majority ownership of all companies by the Bruker BioSpin Group Shareholders as an affiliated stockholder group. As a result, the transactions will be accounted for at historical carrying value.

REGULATORY MATTERS (see page [46])

Under U.S. antitrust laws, the companies may not complete the Bruker BioSpin Inc. transaction until Bruker BioSciences has notified the Antitrust Division of the Department of Justice and the Federal Trade Commission of the transaction and filed the necessary report forms, and until a required waiting period has ended. Bruker BioSciences intends to file the required information and materials to notify the Department of Justice and the Federal Trade Commission of the transactions in December, 2007. In addition, Bruker BioSciences must obtain any consents, authorizations, approvals, filings or exemptions in connection with compliance with the rules of the NASDAQ and make such filings and

approvals as are required to be made or obtained under the securities or "Blue Sky" laws of various states in connection with the issuance of Bruker BioSciences common stock.

We cannot assure you that we will obtain all regulatory approvals to complete the acquisition or that the granting of these approvals will not involve the imposition of conditions on the completion of the acquisition or require changes to the terms of the acquisition. These conditions or changes could result in the conditions to the acquisition not being satisfied.

COMPLETION AND EFFECTIVENESS OF THE TRANSACTIONS (see page [45])

We will complete the transactions when all of the conditions to completion of each of the transaction agreements are satisfied or waived in accordance with the relevant agreement. We expect to complete the transactions and the combination of businesses during the first calendar quarter of 2008.

Dividend Information

We have not declared or paid any dividends on Bruker BioSciences' common stock since our inception and do not intend to pay any dividends on our common stock in the foreseeable future. We currently intend to retain available funds for use in our business. Any determination to pay dividends in the future will be at the discretion of our board of directors and will depend upon, among other things, our financial condition, results of operations and capital requirements. The terms of some of our outstanding indebtedness and new credit facilities prohibit us from paying cash dividends.

Historically, the companies of the Bruker BioSpin Group have from time to time declared and paid dividends to shareholders from retained earnings. In accordance with German and Swiss law, dividends from the German and Swiss companies have been declared and paid only from retained earnings (after deduction of certain reserves) shown in the companies' local statutory financial statements, which differs from that shown on U.S. GAAP financial statements as a result of different bases of accounting.

In November 2007, Bruker BioSpin Invest declared a dividend to shareholders of 75 million Swiss Francs, or approximately $66.7 million based on the exchange rate of $0.89 U.S. Dollars per Swiss Franc as of December 5, 2007, which will be paid to shareholders in December, 2007 prior to the consummation of the proposed transactions. In July 2007, Bruker BioSpin Inc. declared and paid dividends to shareholders of $5.0 million. In April 2007, Bruker BioSpin Invest declared and paid dividends to shareholders of $37.6 million.

In 2006 and 2005, Bruker BioSpin Invest declared and paid dividends of approximately $28.9 million and $22.2 million, respectively. In 2006 and 2005, Bruker BioSpin Inc. declared and paid

dividends of $0 and $5.0 million respectively. In 2006 and 2005, Bruker Physik declared and paid dividends of approximately $0.5 million and $6.4 million, respectively.

The following table sets forth dividends declared by the combined Bruker BioSpin Group during the nine months ended September 30, 2007 and 2006, and for the fiscal years ended December 31, 2007, 2006, 2005, 2004, 2003 and 2002.

RISK FACTORS

In addition to the other information included or incorporated by reference in this proxy statement, including the Risk Factors contained in Bruker BioSciences' Annual Report on Form 10-K and Quarterly Reports on Form 10-Q, you should carefully consider the matters described below relating to the proposed combination in deciding whether or not to vote for the proposals presented in this proxy statement. Additional risks and uncertainties not presently known to Bruker BioSciences or that are not currently believed to be material, if they occur, also may adversely affect the proposed combination of the Bruker BioSpin Group and/or the combined company post-combination.

Although Bruker BioSciences expects that the combination with the Bruker BioSpin Group will result in benefits to Bruker BioSciences, the combined company may not realize those benefits because of integration difficulties and other challenges.

The success of the combination with the Bruker BioSpin Group will depend, in part, on the ability of Bruker BioSciences to realize the potential synergies, cost savings and growth opportunities from integrating the business of the Bruker BioSpin Group with the business of Bruker BioSciences. Bruker BioSciences' success in realizing these benefits and the timing of this realization depends upon the successful integration of the operations of the Bruker BioSpin Group. The difficulties of combining the operations of the companies of the Bruker BioSpin Group with those of Bruker BioSciences' operating subsidiaries, Bruker AXS, Bruker Daltonics and Bruker Optics, include, among others:

•: consolidating research and development operations while preserving the research and development activities and important relationships of each of the operating subsidiaries;
•: retaining key employees;
•: consolidating corporate and administrative infrastructures;
•: integrating and managing the technology of the companies; and
•: minimizing the diversion of management's attention from ongoing business concerns.

Bruker BioSciences cannot assure you that the integration of the Bruker BioSpin Group will result in the realization of the full benefits which the company anticipates will result from the combination.

The market price of Bruker BioSciences common stock may decline as a result of the combination with the Bruker BioSpin Group.

The market price of Bruker BioSciences' common stock may decline as a result of the combination with the Bruker BioSpin Group if:

•: Bruker BioSciences does not achieve the perceived benefits of the combination as rapidly as, or to the extent anticipated by, financial or industry analysts; or
•: The effect of the combination on Bruker BioSciences' financial results is not consistent with the expectations of financial or industry analysts. Accordingly, investors may experience a loss as a result of a decreasing stock price and Bruker BioSciences may not be able to raise future capital, if necessary, in the equity markets.

As a result of the transactions, our overall debt level will increase, which may limit our ability to obtain future financing and may affect the growth of our business.

As a result of the transactions, our overall debt level will increase from approximately $48.7 million at September 30, 2007, to approximately $400.0 million at such date on a pro forma basis after giving effect to the transactions. After the completion of the transactions, our level of debt and

other obligations could have significant adverse consequences on the business and future prospects of the combined company, including the following:

•: the combined company may not be able to obtain financing in the future for working capital, capital expenditures, acquisitions, debt service requirements or other purposes;
•: less levered competitors could have a competitive advantage because they have lower debt service requirements; and
•: the combined company may be less able to take advantage of significant business opportunities and to react to changes in market or industry conditions than its competitors due to payments required on its credit facilities.

Some directors and executive officers of Bruker BioSciences have interests in the transactions that may differ from or are in addition to the interests of Bruker BioSciences stockholders, including, if the transactions are completed, the receipt of financial and other benefits.

Our chief executive officer and chairman of the board, Frank H. Laukien, and the other members of the Bruker BioSpin Group Shareholders own stock in both Bruker BioSciences and the Bruker BioSpin Group. Bruker BioSpin Group Shareholders own or control 100% of the shares of the Bruker BioSpin Group. 57,544,872 shares of Bruker BioSciences common stock will be issued to the Bruker BioSpin Group Shareholders, in connection with the combination. Following the combination, the Bruker BioSpin Group Shareholders, would own, in the aggregate, approximately 69% of the outstanding shares of common stock of Bruker BioSciences. The Bruker BioSpin Group Shareholders will also receive $388 million in cash as part of the transaction consideration. In addition, prior to the closing of the transactions, the Bruker BioSpin Group companies will make a one time 75 million Swiss Franc dividend payment (approximately $66.7 million based on the exchange rate of $0.89 U.S. Dollars per Swiss Franc on December 5, 2007) to the Bruker BioSpin Group Shareholders. Although the Bruker BioSciences' board of directors appointed an independent special committee to determine the advisability of and to negotiate the terms of the transactions, you should take the potential conflicts of interest of the Bruker BioSpin Group Shareholders into account when considering the recommendations of the special committee and of the board of directors.

The combination with the Bruker BioSpin Group is subject to the receipt of consents and approvals from government entities that may not be received or that may impose conditions that could have an adverse effect on Bruker BioSciences following the completion of the transactions.

We cannot complete the combination with the Bruker BioSpin Group unless we and the Bruker BioSpin Group receive various consents, orders, approvals and clearances from antitrust and other authorities in the United States and possibly other countries. While we believe we will receive the requisite regulatory approvals from these authorities, there can be no assurance of this. In addition, the authorities may impose conditions on the completion of the transactions or require changes to the terms of the combination. For example, the authorities may require divestiture of certain assets as a condition of closing any or all of the transactions. Bruker BioSciences is not obligated to agree to divest material assets in order to obtain regulatory approval of the proposed combination with the Bruker BioSpin Group. While Bruker BioSciences does not currently expect that any such conditions or changes would be imposed, there can be no assurance that they will not be, and such conditions or changes could have the effect of delaying completion of the combination with the Bruker BioSpin Group or imposing additional costs on Bruker BioSciences.

The issuance of 57,544,872 shares of Bruker BioSciences common stock to the shareholders of the Bruker BioSpin Group companies in the combination will substantially reduce the percentage interests of Bruker BioSciences stockholders.

If the transactions are completed, 57,544,872 million shares of Bruker BioSciences common stock will be issued to current shareholders of the Bruker BioSpin Group, and former Bruker BioSpin Group shareholders will own approximately 69% of the outstanding common stock of Bruker BioSciences after the transactions. The issuance of these shares to current shareholders of the Bruker BioSpin Group will cause a reduction in the relative percentage interests of current Bruker BioSciences stockholders in earnings, voting, liquidation value and book and market value. The issuance of shares of Bruker BioSciences common stock at any implied premium would likely result in dilution to the market price of Bruker BioSciences common stock. The issuance of additional shares in future transactions could further reduce the percentage interests of current Bruker BioSciences stockholders and Bruker BioSpin Group shareholders.

The Bruker BioSpin Group operates in a mature market and has achieved a high market share and, as a result, the potential for future growth may be limited.

The markets for NMR, research MRI and EPR are well established. The Bruker BioSpin Group has a high market share and, as a result, future growth may be limited to the growth of the overall market for NMR, research MRI and EPR products. While this growth has been steady, when measured over long time periods, future growth may depend on new applications developed by academic and industrial customers, and in most cases outside the control of the Bruker BioSpin Group.

The increasing prices of metal raw materials and superconducting wire could adversely affect the gross margins and profitability of the Bruker BioSpin Group and its superconducting wire business.

The last few years have seen sharp increases in the prices for various raw materials, in part due to high demand from developing countries. The Bruker BioSpin Group relies on some of these materials for the production of its products. In particular, for the Bruker BioSpin Group's superconducting magnet production, both for the horizontal and vertical magnet series, the Bruker BioSpin Group relies on the availability of copper, steel and the metallic raw materials for traditional low-temperature superconducting wires. Higher prices for these commodities will increase the production cost of superconducting wires and superconducting magnets and may adversely affect gross margins.

The price of copper has increased significantly over the last decade. Since copper is a main constituent of low temperature superconductors, this may affect the price of superconducting wire. This type of increase would have an immediate effect on the production costs of superconducting magnets and may negatively affect the profit margins for those products. In addition, an increase in raw material cost affects the production cost of the superconducting wire produced by the Bruker BioSpin Group.

The emerging risk of liquid helium becoming scarce and significantly more expensive could dampen the demand for NMR and research MRI products.

The demand for helium has risen sharply over the last decade. The superconducting magnets used in magnetic resonance rely on liquid helium for their operation. The high global demand, in combination with a shortage in supply, has caused prices for liquid helium to rise significantly. This has an adverse effect on the operating costs for magnetic resonance equipment, and may dampen demand for NMR, EPR and research MRI magnets in the future.

The Bruker BioSpin Group has always operated as a private company and does not have in place the financial organization, reporting and controls necessary for a public company.

Since its formation, the Bruker BioSpin Group has always operated as a private company. It has never put in place the financial organization, reporting and controls which are required for a U.S. public company. The cost of implementing this type of financial organization, reporting and controls may be significant, and compliance with U.S. public company requirements, including those implemented as part of the Sarbanes-Oxley Act 2002, may have an adverse effect on the operations of the Bruker BioSpin Group. If those limitations caused Bruker BioSciences to miss a reporting deadline or otherwise not comply with an applicable law or regulation, Bruker BioSciences might, among other things, be unable to use a Form S-3 registration statement for twelve months, have a material weakness in its internal controls or violate its bank covenants.

The Bruker BioSpin Group develops and manufactures superconducting magnets with significant product liability risks.

The nuclear magnetic resonance (NMR), research magnetic resonance imaging (MRI), Fourier transform mass spectrometry (FTMS), and certain electron paramagnetic resonance (EPR) magnets of the Bruker BioSpin Group utilize high magnet fields and cryogenics to operate at approximately 4 Kelvin, the temperature of liquid helium. There is an inherent risk of potential product liability due to the existence of these high magnetic fields, associated stray fields outside the magnet, and the handling of the cryogens associated with superconducting magnets.

The Bruker BioSpin Group depends on various sole source suppliers.

The Bruker BioSpin Group obtains various components for its products from sole or limited source suppliers. There are limited, if any, available alternatives to these suppliers. The existence of shortages of these components or the failure of delivery with regard to these components could have a material adverse effect upon the Bruker BioSpin Group's revenues and margins. In addition, price increases from these suppliers could have a material adverse effect upon the gross margins of the Bruker BioSpin Group.

•: to transact such other business as may properly come before the meeting or any adjournment or postponement thereof.

Although the above proposals are separate matters to be voted upon by the stockholders of Bruker BioSciences in connection with the various transactions, the first through the third proposals are expressly conditioned upon the approval of the other two proposals. Even if the stockholders of Bruker BioSciences approve one of these proposals, Bruker BioSciences will not complete the transaction contemplated by that proposal unless the stockholders also approve the other proposals, so that all transactions can be completed as described in this proxy statement.

Although the above proposals are separate matters to be voted upon by the stockholders of Bruker BioSciences in connection with the various transactions, the fourth through the seventh proposals are expressly conditioned upon the approval of the other proposals. Even if the stockholders of Bruker

BioSciences approve one of these proposals, Bruker BioSciences will not complete the transaction contemplated by that proposal unless the stockholders also approve the other proposals, so that all transactions can be completed as described in this proxy statement.

Record Date

Only stockholders of record at the close of business on December 18, 2007 are entitled to notice of and to vote at the Special Meeting. On December 18, 2007, Bruker BioSciences had outstanding and entitled to vote [•] shares of common stock. Each outstanding share of common stock entitles the record holder to one vote. Votes will be tabulated by our transfer agent and the inspector of elections, who will be one of our employees or one of our attorneys.

Vote Required for Approval

Transactions and Share Issuance. The transactions contemplated by each of the U.S. stock purchase agreement, the German share purchase agreement and the Swiss merger agreement, including the share issuance, must be approved by the affirmative vote of the holders of a majority of the shares of Bruker BioSciences common stock present or represented by proxy at the Special Meeting and entitled to vote. The transactions contemplated by the U.S. stock purchase agreement, the German share purchase agreement and the Swiss merger agreement must also be approved by the affirmative vote of holders of shares of Bruker BioSciences common stock who are unaffiliated with the Bruker BioSpin Group Shareholders and who represent at least a majority of the total votes cast by these unaffiliated holders at the Special Meeting.

Proposals to Amend our Certificate of Incorporation. The affirmative vote of the holders of a majority of the shares of Bruker BioSciences common stock outstanding as of the record date is required to adopt and approve each of the proposals to amend our certificate of incorporation.

Amendment to Stock Option Plan. The affirmative vote of the holders of a majority of the shares of Bruker BioSciences common stock present or represented by proxy at the Special Meeting and entitled to vote is required to approve the amendment to the Amended and Restated 2000 Stock Option Plan.

Elections of Directors. Directors shall be elected by a plurality of the votes of the shares of common stock present in person or represented by proxy at the Special Meeting and entitled to vote. This means that the two candidates for election as directors at the Special Meeting who receive the highest number of affirmative votes will be elected.

As of the record date, Bruker BioSciences directors and executive officers and their affiliates owned approximately 52% of the outstanding shares of Bruker BioSciences' common stock. The Bruker BioSpin Group Shareholders, including Frank H. Laukien, Dirk Laukien and Joerg Laukien, who are parties to the U.S. stock purchase agreement, the German share purchase agreement and the Swiss merger agreement, have covenanted under the terms of those agreements to vote all of their shares of Bruker BioSciences in favor of the transactions and related share issuance. These shares represent approximately 52% of the voting power of Bruker BioSciences entitled to vote at the stockholder meeting and, under our bylaws and NASDAQ rules, are sufficient to approve the proposals regarding the transactions and related share issuance. However, the terms of each transaction agreement provide that the transactions contemplated by the transaction agreements are subject to approval by holders of shares of Bruker BioSciences common stock who are unaffiliated with the Bruker BioSpin Group Shareholders and who represent at least a majority of the total votes cast by these unaffiliated holders at the Special Meeting.

Voting of Proxies; Quorum; Abstentions and Broker Non-Votes

If the enclosed Proxy Card is properly executed and returned, it will be voted in the manner directed by the stockholder. If no instructions are specified with respect to any particular matter to be

acted upon, proxies will be voted in favor of such matter. In addition, if other matters come before the meeting, the persons named in the accompanying proxy and acting thereunder will have discretion to vote on those matters in accordance with their best judgment. Any person signing the enclosed form of proxy has the power to revoke it by voting in person at the meeting, by giving written notice of revocation to the Secretary of Bruker BioSciences at 40 Manning Road, Billerica, Massachusetts 01821 at any time before the proxy is exercised or by granting a subsequently dated proxy. Please note, however, that if your shares are held of record by a broker, bank or nominee and you wish to vote at the meeting, you will not be permitted to vote in person unless you first obtain a proxy issued in your name from the record holder.

The holders of a majority in interest of all of the Bruker BioSciences common stock, par value $.01 per share, issued, outstanding and entitled to vote are required to be present in person or be represented by proxy at the Special Meeting in order to constitute a quorum for the transaction of business. Each share of common stock outstanding on the record date will be entitled to one vote on all matters.

Because abstentions with respect to any matter are treated as shares present or represented and entitled to vote for the purposes of determining whether that matter has been approved by the stockholders, abstentions have the same effect as negative votes for each proposal other than the vote to elect directors. Broker non-votes are not deemed to be present or represented for purposes of determining whether stockholder approval of that matter has been obtained, but they are counted as present for purposes of determining the existence of a quorum at the Special Meeting.

Solicitation of Proxies

Bruker BioSciences will bear the cost of the solicitation. Although it is expected that the solicitation will be primarily by mail, regular employees or representatives of Bruker BioSciences (none of whom will receive any extra compensation for their activities) may also solicit proxies by telephone, telecopier and in person and arrange for brokerage houses and other custodians, nominees and fiduciaries to send proxies and proxy materials to their principals at the expense of Bruker BioSciences.

Recommendations of the Board of Directors

The board of directors of Bruker BioSciences unanimously determined that each of the transaction agreements and the transactions contemplated by the transaction agreements including the combination with the Bruker BioSpin Group are advisable, voted to approve each of the transaction agreements and recommends that the stockholders vote:

At the Special Meeting, holders of Bruker BioSciences common stock are being asked to vote on, among other items, the acquisitions of Bruker BioSpin Inc., Bruker Physik, and Techneon and the merger of Bruker BioSpin Beteiligungs with and into Bruker BioSpin Invest, and the issuance of shares of Bruker BioSciences common stock in connection with the transactions.

The combination will not be completed unless Bruker BioSciences' stockholders approve each of the transactions and the issuance of shares of Bruker BioSciences common stock in connection with the transactions.

Background of the Combination

From time to time, the board of directors of Bruker BioSciences and the Bruker BioSpin Group Shareholders, each have separately considered strategic alternatives and business combinations.

During January, February and March 2007, the Bruker BioSpin Group Shareholders considered the possibility of a business combination with Bruker BioSciences. While the Bruker BioSpin Group Shareholders did not reach any conclusion during their discussions, the Bruker BioSpin Group Shareholders agreed that they would continue their internal deliberations.

On April 2, 2007, during a telephonic meeting of the board of directors of Bruker BioSciences, Frank Laukien, the Chairman, Chief Executive Officer and President of Bruker BioSciences, who is also one of the owners of the Bruker BioSpin Group and an officer and director of various of the Bruker BioSpin Group of companies, informed the Bruker BioSciences board of directors of the possible interest of the Bruker BioSpin Group Shareholders in considering a business combination. The board discussed the possibility of a potential transaction and various considerations relating to such a transaction. The board considered the establishment of a special committee to deal with such a possible transaction, but determined that the topic should be deferred pending further consideration at the next board meeting.

After the April 2, 2007 Bruker BioSciences Board telephonic meeting, the independent directors of Bruker BioSciences established an informal working group of independent directors to consider the possibility of a future business combination with the Bruker BioSpin Group. William Linton, the lead director of Bruker BioSciences, was joined on the informal working group by Collin D'Silva and Richard Kniss.

In April 2007, the independent working group established informal contacts with three investment banks in order to obtain their initial reaction and informal views on a potential acquisition of the

Bruker BioSpin Group. Two investment banks were invited to give telephonic presentations to the informal working group in April 2007, including strategic rationale, potential investor perception and potential valuation ranges.

At a May 2, 2007 board of directors meeting of Bruker BioSciences, Mr. Linton presented the board with an update of the informal working group's views on a potential business combination with the Bruker BioSpin Group, assuming the Bruker BioSpin Group Shareholders would be interested in pursuing such a transaction. Frank Laukien and William Knight, the Bruker BioSciences Chief Financial Officer, also informed the board that several significant financial investors in Bruker BioSciences during recent visits to the company and during phone conversations had urged Bruker BioSciences to very seriously consider and explore a potential combination with the Bruker BioSpin Group.

During April, May, June and July 2007, the Bruker BioSpin Group Shareholders continued their deliberations concerning the desirability of a potential combination with Bruker BioSciences while the independent working group of the Board had various discussions with Frank Laukien regarding the possible transaction.

On July 18, 2007, four of the owners of the Bruker BioSpin Group met and decided that the feasibility, desirability and structural/tax consequences of a business combination with Bruker BioSciences should be more seriously explored and that discussions of that topic with the independent directors on the board of Bruker BioSciences should be initiated.

On August 1, 2007, at a meeting of the Bruker BioSciences board of directors, Frank Laukien informed the Board of this more serious interest from the owners of the Bruker BioSpin Group. The board engaged in an extensive discussion regarding the rationale for a possible business combination and strategic alternatives. Among the topics discussed were the benefit to customers, the impact on the public stockholders of Bruker BioSciences, synergies, the Bruker BioSpin Group financial results and the Bruker BioSpin Group forecast. The various conflicts present in connection with a possible transaction with the Bruker BioSpin Group were also discussed. The board decided that if the matter were to proceed, it should do so under the auspices of the independent directors. As a result, the board of directors created a special committee of independent directors, consisting of Messrs. Linton, D'Silva and Kniss, and chaired by lead director William Linton.

All members of the special committee are independent directors within the meaning of the listing standards of the NASDAQ Stock Market, and are unaffiliated with the Bruker BioSpin Group Shareholders. The tasks of the special committee were: (i) to consider the advisability of the proposed acquisition of the Bruker BioSpin Group, (ii) if it concluded that the acquisition was advisable, to negotiate on behalf of Bruker BioSciences, (iii) to negotiate the terms of the acquisition, and (iv) to recommend to the board of directors of Bruker BioSciences whether the acquisition was in the best interest of the stockholders of Bruker BioSciences who are not affiliated with the Bruker BioSpin Group Shareholders. The special committee was authorized to retain its own financial and legal advisers to assist it in discharging those responsibilities. The board received presentations on the Bruker BioSpin Group by Barbara Burgess, the Vice President of Finance and Chief Accounting Officer of the Bruker BioSpin Group companies located in the United States, Mark Chaykovsky, the Executive Vice President of U.S. NMR Sales for the Bruker BioSpin Group and Werner Maas, an Executive Vice President of the Bruker BioSpin Group.

During the August 1, 2007 board meeting, the owners of the Bruker BioSpin Group also communicated that Dirk Laukien and Joerg Laukien together would be the designated negotiators for the Bruker BioSpin Group, and that Bernhard Wangler would in particular represent the interests of Bruker BioSpin's largest shareholder Isolde Laukien. It was also determined that for the purposes of a potential Bruker BioSciences acquisition of the Bruker BioSpin Group, Frank Laukien, as well as director and counsel Richard Stein and his law firm Nixon Peabody LLP, would support all parties in

the process in a neutral fashion with information, due diligence, tax and structure advice and logistical support, but would not be negotiating for either party.

On August 13, 2007, the special committee held its first meeting. At that meeting, the committee retained Dewey & LeBoeuf LLP to act as its legal advisor. Dewey Ballantine LLP, a predecessor of Dewey & LeBoeuf, previously acted as legal advisor to the special committee of Bruker BioSciences' board of directors in connection with the acquisition of Bruker Optics Inc. and as advisor to the special committee of Bruker Daltonics' board of directors in connection with its merger with Bruker AXS in 2003. Also at that meeting, the committee members reviewed their qualifications and confirmed that they were free from conflicts of interest with respect to the Bruker BioSpin Group owners. Representatives of Dewey & LeBoeuf briefed the committee on its fiduciary duties and the anticipated operation of the special committee process.

On August 16, 2007, the special committee interviewed potential financial advisors. The committee subsequently determined to retain Bear, Stearns & Co. Inc. as its financial advisor. Bear Stearns previously acted as financial advisor to the special committee of Bruker BioSciences' board of directors in connection with the acquisition of Bruker Optics Inc. and as financial advisor to the special committee of Bruker Daltonics' board of directors in connection with its merger with Bruker AXS in 2003.

Throughout the period from mid-August through the end of November 2007, members of Bruker BioSpin Group management, members of the special committee and their respective financial, legal and tax advisors in the United States, Germany and Switzerland engaged in a series of meetings, telephone conference calls and email exchanges to consider and discuss various valuation, structural, due diligence and tax issues related to the proposed business combination, including those meetings referred to below.

On October 3, 2007, the special committee met with its advisors and Bruker BioSciences management. At this meeting, Mr. Linton reported the results of the September 30, 2007 meeting and representatives of Bear Stearns reported the results of the October 2, 2007 meeting. Bruker BioSciences management delivered to the special committee an analysis of Bruker BioSciences' strategic rationale for the possible combination and potential synergies arising from such combination.

On October 9, 2007, the special committee met with its advisors to review the status of the negotiations with the owners of the Bruker BioSpin Group regarding valuation. After a thorough review of the prospects of the Bruker BioSpin Group and potential synergies from the combination, the special committee authorized Mr. Linton to convey an updated view as to the valuation of the Bruker BioSpin Group.

On October 11, 2007, a proposed letter of intent was presented to the shareholders of the Bruker BioSpin Group by Dewey & LeBoeuf on behalf of the special committee.

On October 12, 2007, a non-binding letter of intent was executed by all parties. The letter of intent provided, among other things, for a purchase price of $388 million in cash, a number of Bruker BioSciences shares equal to $526 million based on the trailing ten trading day average closing price of Bruker BioSciences common stock ending two trading days prior to the signing of the transaction agreement, provided that the average closing price was between $8.25 and $9.15 per share, a pre-closing dividend payable by Bruker BioSpin Group to its shareholders of $66 million (later modified to 75 million Swiss francs) and commitments by these shareholders to negotiate exclusively with Bruker BioSciences and to grant Bruker BioSciences and its advisors full access to its operations to conduct due diligence. The letter of intent also provided that the execution of definitive agreements for the transaction would be conditioned on delivery of satisfactory Bruker BioSpin Group financial statements as of and for the periods ended September 30, 2007 and 2006 and the satisfactory completion by Bruker BioSciences of its financial, legal and business due diligence investigation of the Bruker BioSpin Group.

The special committee's advisors initially met with representatives of the Bruker BioSpin Group to commence their due diligence investigation on October 16, 2007. During the following weeks, the special committee's advisors met with Bruker BioSpin Group representatives on numerous occasions, reviewed legal and financial documents and conducted site visits at Bruker BioSpin Group facilities.

On November 30, 2007, the special committee met with its advisors to discuss the status of the negotiation of the transaction agreements.

On December 1, 2007, the Bruker BioSpin Group unaudited financial statements as of and for the periods ended September 30, 2007 and 2006 and the audited financial statements as of and for the periods ended December 31, 2006 and 2005 were distributed to the Bruker BioSciences board of directors.

Also at this meeting, Bear Stearns delivered its oral opinion, which was subsequently confirmed in writing, that as of December 2, 2007, and based upon and subject to the assumptions, qualifications and limitations set forth in the written opinion, the aggregate consideration to be issued in the transactions was fair, from a financial point of view, to the holders of Bruker BioSciences shares, excluding the holders of Bruker BioSciences shares who also own shares of the Bruker BioSpin Group companies. Dewey & LeBoeuf provided a summary of the terms of the transaction. The special committee then voted unanimously to approve the transaction and to recommend its approval by the full board of Bruker BioSciences.

Reasons for the Combination

The Bruker BioSciences board of directors and the Bruker BioSciences special committee considered a number of factors and additional benefits for Bruker BioSciences' stockholders that could result from the combination. These factors and potential benefits include:

•: The complementary nature of the businesses of Bruker BioSciences' subsidiaries, Bruker AXS, Bruker Daltonics and Bruker Optics, with that of the Bruker BioSpin Group would allow for potential strategic benefits, including enhancing Bruker BioSciences' position as a leading tools supplier for life science and materials research, offering a broader technology base, and providing an increased distribution, sales and service infrastructure;
•: Acquiring the Bruker BioSpin Group would allow Bruker BioSciences to increase its critical mass competitively and improve its worldwide geographical distribution coverage in the Americas, Europe and Asia;
•: The combined companies, with expected 2007 pro forma revenues of greater than $900 million, together will be able to better leverage the excellent "Bruker" brand recognition among customers, and will make the combined company a large player in the analytical instruments and life-science tools industry; the nearly doubled larger overall combined company size may positively affect certain customer vendor selections in cases where customers prefer to buy from large companies in the industry.
•: The sales groups of Bruker BioSciences' subsidiaries and the Bruker BioSpin Group will be able to offer jointly each other's products, providing opportunities to supply customers with unique equipment packages that have a broader range of applications and value. In selected locations, Bruker BioSciences' products can be showcased together with the Bruker BioSpin Group's products, providing greater visibility to customers and emphasizing the synergies among the products;
•: The combination offers certain cost savings in areas of marketing through the use of joint representation at trade shows and other events. In addition, lead generation can increase for the integrated company as customer databases are integrated;
•: Joint R&D projects can offer opportunities to provide new solution strategies for customers;
•: The NMR technologies of the Bruker BioSpin Group and the accurate-mass electrospray time-of-flight (ESI-TOF) mass spectrometers of Bruker Daltonics are particularly complementary in small molecule analysis applications in metabolomics, nutritional research, toxicology, forensics, and small molecule biomarker research and validation;
•: The ultra-high field NMR technologies of the Bruker BioSpin Group and the single-crystal diffraction X-ray spectrometers of Bruker AXS are particularly complementary in small molecule and protein three-dimensional structure determination;
•: The combined Bruker BioSpin and Bruker Daltonics operating companies will post-closing explore a combined effort in clinical research systems, molecular diagnostics and molecular imaging, drawing primarily on NMR, research MRI and mass spectrometry technologies;
•: The established corporate governance, as well as the financial and controlling organizations of Bruker BioSciences, can assist the Bruker BioSpin Group in NASDAQ and SEC compliance, introduction of Sarbanes-Oxley control processes, etc. in a cost-effective manner, and without significant expected increases in the general and administrative expenses of the Bruker BioSpin Group;
•: The transaction on a pro forma basis is highly accretive for Bruker BioSciences shareholders for the year 2006 and for the nine-month period ending September 30, 2007;

•: The debt leverage planned after the closing of the transaction and the funding of the planned senior credit facility is considered conservative, the interest spreads achieved are considered favorable, the planned debt push-down structure is considered reasonably tax effective, and the combined expected cash-flow profile of the combined companies is expected to allow steady interest payments and significant principal repayments over the five year term of the senior credit facility;
•: Various financial investors in Bruker BioSciences in 2007 have expressed a strong preference for a potential acquisition by Bruker BioSciences of the Bruker BioSpin Group, if done for a reasonable valuation and parameters; these financial investors, not affiliated with the shareholders of the Bruker BioSpin Group, urged the Bruker BioSciences management to pursue this transaction, as the investors expect additional opportunities to increase shareholder value from the combination; and
•: The oral opinion of Bear Stearns to the Bruker BioSciences special committee on December 2, 2007, subsequently confirmed by a written opinion, also dated December 2, 2007, that, as of December 2, 2007, and based upon and subject to the assumptions, qualifications, and limitations set forth therein, the aggregate consideration to be issued in the transactions was fair, from a financial point of view, to the holders of Bruker BioSciences shares, excluding the holders of Bruker BioSciences shares who also own shares of the Bruker BioSpin Group companies. The full text of Bear Stearns' written opinion, dated December 2, 2007, which sets forth the assumptions made, matters considered and limitations on the review undertaken by Bear Stearns, is attached as Annex B and is incorporated into this proxy statement by reference.

In addition, the Bruker BioSciences' board of directors took into consideration the unanimous recommendation of the Bruker BioSciences' special committee.

The Bruker BioSciences' board of directors and the Bruker BioSciences' special committee also identified a number of risks and uncertainties in its deliberations concerning the acquisition, including the following:

•: The need to integrate the Bruker BioSpin Group into Bruker BioSciences' financial and information systems;
•: The risk of diverting management focus and resources from other strategic opportunities and from operational matters while working to implement the combination;
•: The risk that the combination would not be consummated; and
•: The risks associated with incurring long-term debt obligations in connection with the financing of the transactions.

The foregoing discussion of the factors considered by the Bruker BioSciences board of directors and the special committee is not intended to be exhaustive but summarizes the material factors considered by the Bruker BioSciences board of directors and the special committee in making its recommendation. In view of the wide variety of factors considered by the Bruker BioSciences board of directors and special committee, neither found it practical to and did not quantify or assign any relative or specific weights to the preceding factors or determine that any factor was of particular importance, nor did it specifically characterize any factor as positive or negative, except as described above. The Bruker BioSciences board of directors and the special committee viewed its decision and recommendation as being based on the totality of the information presented. In addition, individual members of the Bruker BioSciences board of directors and the special committee may have given differing weights to differing factors and may have viewed certain factors more positively or negatively than others. Throughout its deliberations, the Bruker BioSciences board of directors and the special

committee consulted with Bruker BioSciences management and their respective legal and financial advisors.

The Bruker BioSciences board of directors and the special committee each concluded that certain of these risks could be managed or mitigated and others were unlikely to occur or have a material impact on the combined company or the transactions, and that, on balance, the potential benefits of the combination outweighed the risks of the combination. For these reasons, the Bruker BioSciences board of directors and the special committee determined the stock purchase agreements and the merger agreement and the transactions contemplated by them, including the issuance of Bruker BioSciences shares as a part of the consideration, are advisable, fair to and in the best interests of Bruker BioSciences and its stockholders, including unaffiliated stockholders, approved (or, in the case of the Bruker BioSciences special committee, recommended approval of) the U.S. stock purchase agreement, the German share purchase agreement and the Swiss merger agreement and recommended that holders of Bruker BioSciences common stock approve the transactions contemplated by the U.S. and German purchase agreements and the Swiss merger agreement, including the issuance of Bruker BioSciences common stock in connection with the combination with the Bruker BioSpin Group.

Recommendation of the Board of Directors and Special Committee

By unanimous vote of the Bruker BioSciences special committee, the Bruker BioSciences special committee determined that the U.S. stock purchase agreement, the German share purchase agreement and the Swiss merger agreement and the transactions contemplated by each of them, including the issuance of Bruker BioSciences shares as a part of the consideration for the combination, are advisable, fair to and in the best interests of Bruker BioSciences and its stockholders, including unaffiliated stockholders, voted to recommend approval of the U.S. and German purchase agreements and the Swiss merger agreement by the board of directors of Bruker BioSciences. By the unanimous vote of the members of the board of directors present at the board meeting and who voted on the transaction (all non-independent directors, namely Frank H. Laukien, Joerg Laukien, Bernhard Wangler and Richard Stein, recused themselves from voting) at the board meeting at which the transaction agreements were considered and voted upon, the Bruker BioSciences board of directors determined that the U.S. and German purchase agreements and the Swiss merger agreement as proposed and the transactions contemplated by them, including the combination and related issuance of shares, are advisable, fair to and in the best interests of Bruker BioSciences and its stockholders, approved the U.S. stock purchase agreement, the German share purchase agreement and the Swiss merger agreement and recommended that holders of Bruker BioSciences common stock vote FOR the transactions contemplated by the U.S. stock purchase agreement, the German share purchase agreement and the Swiss merger agreement, including the issuance of Bruker BioSciences common stock as part of the consideration for the combination with the Bruker BioSpin Group.

In considering the recommendation of the Bruker BioSciences board of directors with respect to the combination with the Bruker BioSpin Group and related issuance of shares, you should be aware that certain directors and executive officers of Bruker BioSciences may have interests in the combination that are different from, or are in addition to, the interests of Bruker BioSciences stockholders. Please see the section entitled "Interests of Certain Directors and Executive Officers in the Combination" that begins on page [44] of this proxy statement.

Bear Stearns' Financial Analyses

Comparable Public Companies Analysis. Bear Stearns performed a comparable public companies analysis to assist the Bruker BioSciences' special committee in valuing the Bruker BioSpin Group based on various financial multiples of selected comparable public companies in the life science instrumentation industry. In performing this analysis, Bear Stearns reviewed certain financial information relating to the Bruker BioSpin Group and compared this information to the corresponding financial information of publicly-traded life science instrumentation companies which Bear Stearns deemed to be generally comparable to the Bruker BioSpin Group.

Bear Stearns compared the projected financial performance and the resulting multiples as of November 30, 2007 of Bruker BioSciences and the resulting multiples of the Bruker BioSpin Group at the implied purchase price in the transaction of $922.6 million, based on BioSciences closing share price of $9.29 on November 30, 2007, to nine publicly traded life science instrumentation companies, which it deemed generally comparable to the Bruker BioSpin Group. Based on the comparability of business dynamics relative to the Bruker BioSpin Group including market focus, customer focus, geographic mix, business mix and projected growth rates, among other things, Bear Stearns divided the nine publicly traded companies into a Tier 1 set consisting of five publicly traded companies and a Tier 2 set consisting of four publicly traded companies as follows:

		Tier 1		Tier 2
		• Thermo Fisher Scientific		• Agilent Technologies, Inc.
		• Waters Corporation		• Mettler-Toledo International Inc.
		• Applied Biosystems Group		• Techne Corporation
		• PerkinElmer, Inc.		• Dionex Corporation
		• Varian, Inc.

Using publicly available information and market data as of November 30, 2007, and in the case of Bruker BioSciences (Management) and the Bruker BioSpin Group, information based on Bruker BioSciences management estimates and using Wall Street research projections for revenue and EBITDA and consensus estimates for EPS and EPS Growth for Bruker BioSciences (Wall Street) and the above comparable companies, Bear Stearns calculated the following harmonic mean multiples for

the above public comparable companies and compared the results to Bruker BioSciences at market and the Bruker BioSpin Group at deal price:

	Tier 1				Tier 2
*Comparable Company Harmonic Mean Multiples:*	Tier 1				Tier 2
*Comparable Company Harmonic Mean Multiples:*	2007E		2008E		2007E		2008E

"Harmonic mean" is calculated by taking the inverse of the average reciprocals of the multiples and gives equal weight to equal dollar investments in the securities whose ratios are being averaged. Bear Stearns utilizes the harmonic mean in averaging ratios in which price is the numerator. "Enterprise Value" is calculated as the sum of the value of the common equity on a fully diluted basis and the value of net debt, any minority interest and preferred stock. "EBITDA" is a company's earnings before interest, taxes, depreciation and amortization. "EPS" is a company's earnings per share. "Growth Rate" for EBITDA is the 2007 to 2008 growth in EBITDA. "Growth Rate" for EPS and net income is the consensus long term growth rate as provided by First Call for Bruker BioSciences and the comparable companies, and for Bruker BioSciences (Management) and the Bruker BioSpin Group, the compounded annual growth rate from 2008 to 2012 in projected net income based on Bruker BioSciences management estimates. "Bruker BioSciences at Market" is defined as Bruker BioSciences' enterprise value and share price based on the closing share price of the Bruker BioSciences common stock as of November 30, 2007. "Bruker BioSpin Group at Deal" is defined as the Bruker BioSpin Group's implied enterprise value and equity value based on the purchase price in the transaction of approximately $388 million in cash and 57,544,872 Bruker BioSciences shares and Bruker BioSciences closing share price on November 30, 2007 and the value of net debt, the pre-closing dividend to the sellers and an estimated tax exposure.

Precedent M&A transaction Analysis. Bear Stearns performed a precedent transactions analysis to assist the Bruker BioSciences' special committee in valuing the Bruker BioSpin Group based on various financial multiples of selected comparable precedent transactions in the life science instrumentation industry. In performing this analysis, Bear Stearns reviewed certain financial information relating to the Bruker BioSpin Group and compared this information to the corresponding financial information of precedent transactions involving life science instrumentation companies which Bear Stearns deemed to be generally comparable to the Bruker BioSpin Group.

Bear Stearns compared the financial performance and the resulting multiples of the Bruker BioSpin Group's enterprise value and equity value based on the purchase price in the transaction to six precedent transactions involving life science instrumentation companies, which it deemed generally comparable to the Bruker BioSpin Group. Such comparable precedent transactions consisted of:

Date Announced		Target/Acquiror
01/29/07		Molecular Devices Corp. / MDS Inc.
06/20/06		Biacore International / GE Healthcare Ltd.
04/17/06		Bruker Optics Inc. / Bruker BioSciences

01/19/05		Kendro Laboratory Products division of SPX Corporation / Thermo Electron Corporation
04/07/03		Bruker AXS / Bruker Daltonics

Using publicly available information, and in the case of the Bruker BioSpin Group, information based on Bruker BioSciences management estimates for the years ending December 31, 2007, 2008 and 2009 and using Wall Street research projections for revenue, EBITDA and net income for the above target companies, Bear Stearns calculated the following harmonic mean multiples for the above comparable precedent transactions:

	Latest Twelve Months		Current Year		Current Year + 1
*Precedent transactions Harmonic Mean Multiples:*

Discounted Cash Flow Analysis. Based on cash flow projections for Bruker BioSciences, the Bruker BioSpin Group and the potential synergies expected to result in the transaction all as prepared by Bruker BioSciences, Bear Stearns performed a discounted cash flow analysis to assist the Bruker BioSciences special committee in valuing the Bruker BioSpin Group, Bruker BioSciences and the pro forma combined company.

In performing its discounted cash flow analysis:

•: Bear Stearns estimated Bruker BioSciences' weighted average cost of capital to be within a range of 11.0-13.0% based on, among other factors, (i) a review of Bruker BioSciences' Bloomberg five-year historical adjusted beta, its Bloomberg two-year historical adjusted beta and its then-current Barra predicted beta (with a bias toward more recent historical and predicted data to more appropriately reflect Bruker BioSciences' risk profile going forward) as well as similar beta information for the comparable companies, (ii) Bear Stearns' estimate of the US equity risk premium, (iii) Bruker BioSciences' assumed target capital structure on a prospective basis and (iv) Bear Stearns' investment banking and capital markets judgment and experience in valuing companies similar to Bruker BioSciences.

•: Bear Stearns estimated the Bruker BioSpin Group's weighted average cost of capital to be within a range of 10.5-12.5% based on, among other factors, (i) a review of the Bloomberg five-year historical adjusted beta, Bloomberg two-year historical adjusted beta and then-current Barra predicted betas for the comparable companies, (ii) Bear Stearns' estimate of the US equity risk premium, (iii) the Bruker BioSpin Group's assumed target capital structure on a prospective basis and (iv) Bear Stearns' investment banking and capital markets judgment and experience in valuing companies similar to the Bruker BioSpin Group.
•: In calculating Bruker BioSciences' and the Bruker BioSpin Group's terminal values for purposes of its discounted cash flow analyses, Bear Stearns used a reference range of terminal enterprise value/trailing EBITDA multiples (based on estimated 2012 EBITDA) of 8.0 to 10.0x. The terminal values implied by the aforementioned terminal multiple reference ranges were cross-checked for reasonableness by reference to implied perpetual growth rates in the terminal year free cash flow.
•: For the potential synergies, Bear Stearns estimated the discount rate to be within a range of 10.5-12.5% and in calculating terminal value for purposes of its discounted cash flow analyses, Bear Stearns used a reference range of perpetual growth rates in terminal free cash flow of 2.0-4.0%.

Discounted cash flow valuations were calculated for the Bruker BioSpin Group on a stand-alone basis using the adjusted Bruker BioSpin Group projections, both including and excluding potential synergies. Bear Stearns derived a range of implied equity values for the Bruker BioSpin Group as follows:

	Range
($ in millions)	Range
($ in millions)	Low			High
Bruker BioSpin Group
Excluding Potential Synergies	$	1,062	—	$	1,282
Including Potential Synergies		1,172	—		1,415

The ranges of implied equity values in the table above compare to the implied purchase price of $922.6 million based on Bruker BioSciences' closing share of $9.29 on November 30, 2007.

Discounted cash flow valuations were also calculated for Bruker BioSciences on a stand-alone basis using the Bruker BioSciences projections and for the pro forma combined company both including and excluding the potential synergies.

Bear Stearns derived a range of implied equity values per share for Bruker BioSciences and the pro forma combined company as follows:

		Range
		Low			High
Bruker BioSciences
	Stand-alone	$	8.97	—	$	11.38
Combined Company
	Excluding Potential Synergies	$	9.85	—	$	12.74
	Including Potential Synergies		10.51	—		13.54

Pro Forma Transaction Analysis. Bear Stearns performed a pro forma transaction analysis to assist the Bruker BioSciences special committee in analyzing the financial impact of the transaction on Bruker BioSciences. Bear Stearns reviewed and analyzed certain pro forma financial impacts of the transaction on holders of Bruker BioSciences based on the following, among other items:

•: a purchase price of approximately $388.0 million in cash and 57,544,872 Bruker BioSciences shares;
•: the financial projections provided to Bear Stearns by the management of Bruker BioSciences for both Bruker BioSciences and the Bruker BioSpin Group and the potential synergies; and
•: an assumption for analytical purposes that there would be no financial statement impact of potential restructuring costs or other one-time costs associated with the transaction and that the transaction was effective as of January 1, 2008.

The following table shows the projected per share accretion / (dilution) to Bruker BioSciences' standalone earnings, including and excluding the potential synergies for the years presented.

Accretion / (Dilution) to Bruker BioSciences' Earnings per Share		2008E			2009E			2010E
Including Potential Synergies		$	0.25		$	0.24		$	0.22
Excluding Potential Synergies			0.22			0.21			0.19

Other Considerations

The preparation of a fairness opinion is a complex process and involves various judgments and determinations as to the most appropriate and relevant assumptions and financial and valuation analyses and the application of those methods to the particular circumstances involved. A fairness opinion is therefore not readily susceptible to partial analysis or summary description, and taking portions of the analyses set out above, without considering the analysis as a whole, would in the view of Bear Stearns create an incomplete and misleading picture of the processes underlying the analyses considered in rendering the Bear Stearns opinion. In arriving at its opinion, Bear Stearns:

•: Based its analyses on assumptions that it deemed reasonable, including assumptions concerning general business and economic conditions, capital markets considerations and industry-specific and company-specific factors.
•: Did not form a view or opinion as to whether any individual analysis or factor, whether positive or negative, considered in isolation, supported or failed to support the Bear Stearns opinion.
•: Considered the results of all its analyses and did not attribute any particular weight to any one analysis or factor.
•: Arrived at its ultimate opinion based on the results of all analyses undertaken by it and assessed as a whole and believed that the totality of the factors considered and analyses performed by Bear Stearns in connection with its opinion operated collectively to support its determination as to the fairness, from a financial point of view, to the holders of Bruker BioSciences shares, excluding the holders of Bruker BioSciences shares who also own shares in the Bruker BioSpin Group companies, of the aggregate consideration to be issued in the transactions.

Bear Stearns also noted that:

•: The analyses performed by Bear Stearns, particularly those based on estimates and projections, are not necessarily indicative of actual values or actual future results, which may be significantly more or less favorable than suggested by these analyses.
•: None of the public companies used in the comparable company analysis described above are identical to Bruker BioSciences or Bruker BioSpin, and none of the precedent merger and

acquisition transactions used in the precedent transactions analysis described above are identical to the acquisition.

•: Accordingly, the analyses of publicly traded comparable companies and precedent merger and acquisition transactions is not mathematical; rather, such analyses involve complex considerations and judgments concerning the differences in financial, operating and capital markets-related characteristics and other factors regarding the companies and precedent merger and acquisition transactions to which Bruker BioSpin and the acquisition were compared.
•: The analyses performed by Bear Stearns do not purport to be appraisals or to reflect the prices at which any securities may trade at the present time or at any time in the future.

The type and amount of consideration payable in the acquisition were determined through negotiations between Bruker BioSciences and Bruker BioSpin and were approved by the Bruker BioSciences special committee and board of directors. The decision to enter into the transaction agreements was solely that of the Bruker BioSciences special committee and board of directors. The Bear Stearns opinion was just one of the many factors taken into consideration by the Bruker BioSciences special committee and board of directors. Consequently, Bear Stearns' analyses should not be viewed as determinative of the decisions of the Bruker BioSciences special committee and board of directors with respect to the fairness, from a financial point of view, to the holders of Bruker BioSciences shares, excluding the holders of BioSciences shares who also own shares in the Bruker BioSpin Group companies, of the aggregate consideration to be issued in the transactions.

Pursuant to the terms of Bear Stearns' engagement letter, Bruker BioSciences has agreed to pay Bear Stearns a customary transaction fee, a substantial portion of which is payable upon consummation of the transaction contemplated by the transaction agreements. A portion of Bear Stearns' compensation was paid upon delivery of its letter and may be credited against the fee payable upon consummation of the acquisition. In addition, Bruker BioSciences has agreed to reimburse Bear Stearns for certain expenses and to indemnify Bear Stearns against certain liabilities arising out of Bear Stearns' engagement.

Bear Stearns has previously been engaged by Bruker BioSciences to provide certain investment banking and other services on matters unrelated to the acquisition, for which Bear Stearns has received customary fees. Bear Stearns may seek to provide Bruker BioSciences and its respective affiliates with certain investment banking and other services unrelated to the acquisition in the future.

Consistent with applicable legal and regulatory requirements, Bear Stearns has adopted certain policies and procedures to establish and maintain the independence of Bear Stearns' research departments and personnel. As a result, Bear Stearns' research analysts may hold views, make statements or investment recommendations and/or publish research reports with respect to Bruker BioSciences, the acquisition and other participants in the acquisition that differ from the views of Bear Stearns' investment banking personnel.

In the ordinary course of business, Bear Stearns and its affiliates may actively trade (for its own account and for the accounts of its customers) certain equity and debt securities, bank debt and/or other financial instruments issued by Bruker BioSciences and its affiliates, as well as derivatives thereof, and, accordingly, may at any time hold long or short positions in these securities, bank debt, financial instruments and derivatives.

Sources of Funds

Bruker BioSciences estimates that the total amount of funds necessary to consummate the combination (including payment of the aggregate cash consideration) will be approximately $398.7 million, which includes $388 million to be paid to shareholders of the Bruker BioSpin Group companies, and the remainder to be applied to pay related fees and expenses in connection with the

transactions and the financing arrangements. These payments are expected to be funded from Bruker BioSciences' available cash, together with a debt financing which Bruker BioSciences expects will be substantially on the terms described below. In connection with the execution and delivery of the stock purchase agreements and the merger agreement, Bruker BioSciences has entered into a commitment letter with J.P. Morgan Securities Inc. and Citibank, N.A. Under this commitment letter, the lenders have proposed to provide up to $380 million in debt financing to Bruker BioSciences, consisting of (i) a term loan facility in an aggregate principal amount of $150 million and (ii) a revolving credit facility in an aggregate principal amount of $230 million, a portion of which will be available as a letter of credit subfacility. Advances under the credit facilities will be available to finance the combination, to pay related fees, costs and expenses in connection with these transactions and to fund the general working capital needs of Bruker BioSciences and its subsidiaries following the combination. Bruker BioSciences' material direct and indirect subsidiaries will guarantee all obligations of Bruker BioSciences, subject to tax considerations and financial assurance limitations, as applicable. In addition, the credit facilities will be secured by all of the capital stock of Bruker BioSciences' domestic subsidiaries and by 65% of the capital stock of various of our foreign subsidiaries. The credit facilities contemplated by the commitment letter are subject to customary closing conditions, including, among others:

•: the execution of definitive credit documentation satisfactory to the lenders;
•: accounting due diligence and the receipt of specified financial statements of Bruker BioSciences;
•: satisfactory due diligence review of Bruker BioSciences and the Bruker BioSpin Group; and
•: receipt of customary closing documents.

As of the date of this proxy statement, no alternative financing arrangements or alternative financing plans have been made in the event this financing is not available as anticipated. The documentation governing the financing has not been finalized and, accordingly, the actual terms may differ from those described in this proxy statement.

Interests of Certain Directors and Executive Officers in the Combination

In considering the recommendation of the board of directors of Bruker BioSciences to vote for the proposals to approve the combination with the Bruker BioSpin Group and the issuance of shares of Bruker BioSciences common stock as part of the consideration for the combination, stockholders of Bruker BioSciences should be aware that some Bruker BioSciences executive officers and directors may have interests in the acquisition that may be different from, or in addition to, those of Bruker BioSciences stockholders.

Following the combination with the Bruker BioSpin Group, Frank H. Laukien, our president, chief executive officer and chairman of the board, and Dirk D. Laukien, currently Bruker BioSciences' senior vice president, will continue in their roles at Bruker BioSciences and as co-chief executive officers of our Bruker BioSpin subsidiaries. If elected by stockholders at the Special Meeting, Dirk Laukien will also become a director of Bruker BioSciences. Joerg Laukien, currently a director of Bruker BioSciences and European chief operating officer of the Bruker BioSpin Group, will continue as European chief operating officer of our Bruker BioSpin subsidiary upon completion of the combination.

In addition to their respective roles as executive officers and directors, Frank Laukien, Dirk Laukien and Joerg Laukien each own stock in both Bruker BioSciences and the companies of the Bruker BioSpin Group. The Bruker BioSpin Group Shareholders control 100% of the shares of the Bruker BioSpin Group, and will receive all of the consideration issued by Bruker BioSciences as a result of the transactions discussed in this proxy statement.

If the acquisition of the Bruker BioSpin Group is approved by stockholders, our directors and officers who are also Bruker BioSpin Group shareholders will receive different amounts of cash and stock as consideration in exchange for their interests in the Bruker BioSpin Group companies. Frank Laukien will receive $69.7 million of cash and 10,034,387 Bruker BioSciences shares which, as of December 5, 2007, have a market value of approximately $122.7 million. Joerg Laukien will receive $72.9 million of cash and 10,789,664 Bruker BioSciences shares which, as of December 5, 2007, have a market value of approximately $132.0 million. Dirk Laukien will receive $72.9 million of cash and 10,789,664 Bruker BioSciences shares which, as of December 5, 2007, have a market value of approximately $132.0 million.

Upon the completion of the purchases of Bruker BioSciences common stock pursuant to the cash-stock exchange agreement among Isolde Laukien-Kleiner, Marc Laukien, Frank Laukien and Robyn Laukien, and giving effect to the resulting reallocation of cash and share proceeds, Frank Laukien will have received net cash consideration of $19.2 million and 15,554,574 Bruker BioSciences shares which, as of December 5, 2007, have a market value of approximately $190.2 million. Also after giving effect to this agreement, Joerg Laukien will have received net cash consideration of $68.6 million and 11,258,741 Bruker BioSciences shares which, as of December 5, 2007, have a market value of approximately $137.7 million. Under a separate cash-stock exchange agreement, completion of which is subject to certain conditions, Frank Laukien may purchase from Dirk Laukien an additional 1,219,733 shares of Bruker BioSciences common stock for approximately $11.1 million. If this transfer is completed, Frank Laukien will have received net cash consideration of $8.1 million and 16,774,307 Bruker BioSciences shares which, as of December 5, 2007, have a market value of approximately $205.1 million. If this transfer is completed, Dirk Laukien will have received net cash consideration of $84.0 million and 9,569,530 Bruker BioSciences shares which, as of December 5, 2007, have a market value of approximately $117.0 million. The cash-stock exchange agreements are more fully described below in the section of this proxy statement under the heading "Cash-Stock Exchange Agreements" on page [47].

As of December 5, 2007, the directors and executive officers of Bruker BioSciences beneficially owned 40,447,364 shares, including stock options exercisable within 60 days of December 5, 2007, representing approximately 39% of the outstanding shares of Bruker BioSciences common stock.

For additional information relating to affiliations of various Bruker BioSciences officers, directors and stockholders, you should read the section entitled "Certain Relationships and Related Party Transactions of Bruker BioSciences" beginning on page [105].

The Bruker BioSciences board of directors was aware of these interests during its deliberation of the merits of the combination and in determining to recommend to the stockholders of Bruker BioSciences that they vote for the proposal to approve the transactions contemplated by the U.S. stock purchase agreement, the German share purchase agreement and the Swiss merger agreement, including the related issuance of shares of Bruker BioSciences common stock.

Completion and Effectiveness of the Combination

The combination will be completed when and if all of the conditions to the completion of the transactions are satisfied or waived.

We are working toward completing the combination as quickly as possible. We expect to complete the combination during the first calendar quarter of 2008.

Structure of the Transaction and Operations Post-Combination

The combination is structured so that (a) Bruker BioSciences will purchase all of the outstanding stock of Bruker BioSpin Inc., Bruker Physik and Techneon from the shareholders of BioSpin Inc.,

Bruker Physik and Techeon, respectively, in a private placement, and (b) Bruker BioSciences, through a reverse triangular merger agreement with Bruker BioSpin Invest, will indirectly acquire the equity of the Bruker BioSpin Invest shareholders. Consideration for the shares of the companies of the Bruker BioSpin Group will consist of a combination of cash and shares of Bruker BioSciences common stock. Bruker BioSciences intends to operate the Bruker BioSpin Group as a wholly owned operation alongside Bruker Daltonics, Bruker AXS and Bruker Optics.

Material United States Federal Income Tax Consequences of the Combination

The acquisitions are not expected to result in any material U.S. federal income tax consequences for Bruker BioSciences stockholders, other than for the owners of Bruker BioSciences shares who are also owners of shares of the Bruker BioSpin Group.

Accounting Treatment of the Acquisition

The combination represents a business combination of companies under common control due to the majority ownership of all companies by the Bruker BioSpin Group Shareholders as an affiliated stockholder group. As a result, the combination will be accounted for at historical carrying value.

Regulatory Matters

We have summarized below the material regulatory requirements affecting the combination. Although we have not yet received all of the required approvals we discuss, we anticipate that we will receive regulatory approvals sufficient to complete the combination during the first calendar quarter of 2008.

Antitrust Considerations. The stock purchase of Bruker BioSpin Inc. is subject to the requirements of the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, which prevents certain merger or acquisition transactions from being completed until required information and materials are furnished to the Antitrust Division of the Department of Justice and the Federal Trade Commission and specified waiting periods are terminated or expire. Bruker BioSciences and Bruker BioSpin Inc. intend to file the required information and materials to notify the Department of Justice and the Federal Trade Commission of the combination during December 2007. The applicable HSR waiting period will expire during January 2008.

The Antitrust Division of the Department of Justice or the Federal Trade Commission may challenge on antitrust grounds, regardless of the fact that the waiting period expired without comment. Accordingly, at any time before or after the completion of this stock purchase, either the Antitrust Division of the Department of Justice or the Federal Trade Commission could take action under the antitrust laws as it deems necessary or desirable in the public interest, or other persons could take action under the antitrust laws, including seeking to enjoin this stock purchase or seeking the divestiture of substantial assets of one of the parties to this stock purchase. Additionally, at any time before or after this stock purchase, notwithstanding that the applicable waiting period expired or was terminated, a private party (including an individual state) may seek to take action under the antitrust laws as it deems necessary or desirable in the public interest. Although we do not expect any conditions to be imposed by the Antitrust Division or the Federal Trade Commission, there can be no assurance that a challenge to this stock purchase will not be made or that, if a challenge is made, we will prevail.

No Appraisal Rights

There are no rights of appraisal or similar rights of dissenters with respect to any matter to be acted upon under this proxy statement. Delaware law does not require that holders of Bruker BioSciences common stock who object to the share issuance and the transactions, and who vote against

or abstain from voting in favor of the issuance and the transactions, be afforded any appraisal or dissenters' rights or the right to receive cash for their shares.

Foreign Regulatory Requirements

Bruker BioSciences is not aware of any material foreign governmental approvals or actions that are required to complete the combination. Bruker BioSciences and the Bruker BioSpin Group conduct operations in a number of foreign countries, some of which have voluntary and/or post-acquisition notification systems. Should any approval or action be required, Bruker BioSciences and the Bruker BioSpin Group currently plan to seek the approval or take the action required. Failure to obtain the approval or take the action is not anticipated to have a material effect on the combination or on Bruker BioSciences.

The transactions are subject to a binding ruling by the three relevant Swiss tax authorities, comprised of the Federal Tax Authorities and the cantonal Tax Authorities of the Cantons of Zurich and Zug, that the amount of withholding taxes required under Swiss law as a result of the transactions will be based on a minimum pre-merger dividend under Swiss law set at $50 million with withholding taxes imposed at a rate of 35% subject to a 20% tax refund. For purposes of obtaining the binding ruling, submitted on November 19, 2007 to the Swiss Federal Tax Authorities for their review were information and materials pertaining to (i) the pre-merger dividend to be distributed; (ii) the acquisition of BBIO Invest AG (Zug) by Bruker BioSciences; and (iii) the upstream merger of BBIO-AG (Zuerich) with and into BBIO Invest AG (Zug). BBIO Invest AG (Zug) is a holding company that contains various of the foreign distribution companies of the Bruker BioSpin Group. BBIO-AG (Zuerich) is a subsidiary of Bruker BioSpin Invest AG, and is the main production and research and development center of the Bruker BioSpin Group, focusing on the development and production of superconducting magnets, radio-frequency electronics, micro-imaging cryogenic and conventional probes, and high throughput automation solutions. BBIO-AG (Zuerich) also provides applications and engineering support for customers in Switzerland and a number of other countries.

A fully executed favorable binding ruling from the relevant Swiss federal and cantonal tax authorities was received on November 28, 2007 adopting a minimum pre-merger dividend set at $50 million.

Restrictions on Sales of Shares Issued In Connection with the Combination

The shares of Bruker BioSciences common stock to be issued in connection with the combination will not be registered under the Securities Act of 1933 and they will not be freely transferable under the Securities Act.

Closing Date

Unless the parties agree otherwise, the closing of the stock purchase will take place on the later of January 23, 2008 or the first business day following the satisfaction or waiver of all of the closing conditions.

Purchase Price-Payment

The U.S. stock purchase agreement provides that Bruker BioSciences shall purchase all of the outstanding shares of Bruker BioSpin Inc. for an aggregate purchase price of $99,962,514, which, after the funding of the escrows described below, will be payable in cash at closing to the Bruker BioSpin Inc. stockholders pro rata in accordance with their respective ownership of the Bruker BioSpin Inc. common stock.

We sometimes refer to this agreement as the German share purchase agreement in this proxy statement.

In addition, a parcel of real property owned equally by Scitek and Isolde Laukien-Kleiner will be sold to Bruker Optik for €1,416,250.

Escrow

Indemnity Escrow. A $92 million escrow fund established pursuant to the U.S. stock purchase agreement, and discussed above, will serve as security for fulfillment by the sellers of their indemnification obligations set forth in the German share purchase agreement. See the discussion set forth above in "The Stock Purchase Agreement with Bruker Biospin Inc.—Escrow—Indemnity Escrow" for additional information regarding the indemnity escrow fund.

Working Capital. A $6.75 million escrow fund established pursuant to the U.S. stock purchase agreement, as discussed above, will serve as security for fulfillment by the sellers of their obligations to deliver a specified amount of working capital in the Bruker BioSpin Group at closing. See the discussion set forth above in "The Stock Purchase Agreement with Bruker Biospin Inc.—Escrow—Working Capital" for additional information regarding the working capital escrow fund.

Representations and Warranties

The German share purchase agreement contains customary representations and warranties made by Bruker Physik, Techneon and Bruker Physik shareholders to Bruker BioSciences, subject, in some cases, to specified exceptions and qualifications contained in the German share purchase agreement or in the disclosure schedule delivered in connection therewith.

The assertions embodied in those representations and warranties were made solely for purposes of the German share purchase agreement and may be subject to important qualifications and limitations. For example, many of Bruker Physik's and Techneon's representations and warranties are qualified by a Material Adverse Effect standard. For purposes of the German share purchase agreement, a "Material Adverse Effect" means any circumstance, change or effect that, individually or in the aggregate with other circumstances, changes or effects, is or is reasonably likely to materially delay or impede the consummation of the transactions contemplated by the German share purchase agreement or be materially adverse to the business, operations (including results of operations), prospects, assets, liabilities, or financial condition of Bruker Physik, Techneon and their subsidiaries taken as a whole; provided, however, that none of the following, either alone or in combination, shall be considered in determining whether there has been a "Material Adverse Effect": (1) events, circumstances, changes or effects (including legal and regulatory changes) that generally affect the industries in which each of Bruker Physik, Techneon and their subsidiaries operate, other than such events, circumstances, changes or effects that disproportionately affect (relative to other industry participants) Bruker Physik, Techneon or their subsidiaries and (2) changes caused by a material worsening of current conditions caused by acts of terrorism or war occurring after the date of the German share purchase agreement.

Some of the representations and warranties in the German share purchase agreement may not be accurate or complete as of any specified date or may be subject to contractual standards of materiality that differ from the standards of materiality under U.S. federal securities laws. For the foregoing reasons, you should not rely on the representations and warranties as statements of factual information.

The representations and warranties regarding Bruker Physik and Techneon and their respective subsidiaries made to Bruker BioSciences, Bruker Optik and Bruker Daltonik by Bruker Physik and Techneon and their respective shareholders relate to, among other things:

•: corporate organization, including due incorporation, good standing, corporate power and qualification to conduct business;

The Swiss Merger Agreement With Bruker Biospin Invest AG

General

On December 2, 2007, we entered into an Agreement and Plan of Merger with Bruker BioSpin Invest AG, which we sometimes refer to as BioSpin Invest in this proxy statement, Bruker BioSpin Beteiligungs AG and the shareholders of BioSpin Invest relating to the merger of Bruker BioSpin Beteiligungs with and into BioSpin Invest and to approve the related issuance of our common stock in connection with the merger. We sometimes refer to this agreement as the Swiss merger agreement in this proxy statement.

Closing Date

Unless the parties agree otherwise, the closing of the merger will take place on the later of January 23, 2008 or the first business day following the satisfaction or waiver of all of the closing conditions.

Purchase Price—Payment

We will pay aggregate consideration of 57,544,872 shares to the BioSpin Invest shareholders, to be paid in restricted unregistered shares of our common stock, which have a market value, as of December 5, 2007, of $703,773,785. Upon consummation of the merger, BioSpin Invest will become an indirect wholly-owned subsidiary of Bruker BioSciences.

Dividend

Prior to the signing of the Swiss merger agreement, BioSpin Invest declared a dividend in the amount of 75 million Swiss Francs (approximately $66.7 million based on the exchange rate of $0.89 U.S. Dollars per Swiss Franc on December 5, 2007) to its shareholders. This dividend will be paid during December 2007, whether or not the transactions discussed in this proxy statement are approved by the stockholders of Bruker BioSciences.

Escrow

Indemnity Escrow. A $92 million escrow fund established pursuant to the U.S. stock purchase agreement, and discussed above, will serve as security for fulfillment by the sellers of their

indemnification obligations set forth in the merger agreement. See the discussion set forth above in "The Stock Purchase Agreement with Bruker Biospin Inc.—Escrow—Indemnity Escrow" for additional information regarding the indemnity escrow fund.

Working Capital. A $6.75 million escrow fund established pursuant to the U.S. stock purchase agreement, as discussed above, will serve as security for fulfillment by the sellers of their obligations to deliver a specified amount of working capital in the Bruker BioSpin Group at closing. See the discussion set forth above in "The Stock Purchase Agreement with Bruker Biospin Inc.—Escrow—Working Capital Escrow" for additional information regarding the working capital escrow fund.

Representations and Warranties

The Swiss merger agreement contains customary representations and warranties made by BioSpin Invest and BioSpin Invest shareholders to Bruker BioSciences, subject, in some cases, to specified exceptions and qualifications contained in the merger agreement or in the disclosure schedule delivered in connection therewith.

The assertions embodied in those representations and warranties were made solely for purposes of the merger agreement and may be subject to important qualifications and limitations. For example, many of BioSpin Invest's representations and warranties are qualified by a Material Adverse Effect standard. For purposes of the Swiss merger agreement, a "Material Adverse Effect" means any circumstance, change or effect that, individually or in the aggregate with other circumstances, changes or effects, is or is reasonably likely to materially delay or impede the consummation of the transactions contemplated by the merger agreement or be materially adverse to the business, operations (including results of operations), prospects, assets, liabilities, or financial condition of BioSpin Invest and its subsidiaries taken as a whole; provided, however, that none of the following, either alone or in combination, shall be considered in determining whether there has been a "Material Adverse Effect": (1) events, circumstances, changes or effects (including legal and regulatory changes) that generally affect the industries in which each of BioSpin Invest and its subsidiaries operate, other than such events, circumstances, changes or effects that disproportionately affect (relative to other industry participants) BioSpin Invest or its subsidiaries and (2) changes caused by a material worsening of current conditions caused by acts of terrorism or war occurring after the date of the merger agreement.

Some of the representations and warranties in the Swiss merger agreement may not be accurate or complete as of any specified date or may be subject to contractual standards of materiality that differ from the standards of materiality under U.S. federal securities laws. For the foregoing reasons, you should not rely on the representations and warranties as statements of factual information.

Termination of the Swiss Merger Agreement

•: we do not receive stockholder approval for the transaction;
•: either the U.S. stock purchase agreement or the German share purchase agreement is terminated; or

Bruker BioSciences may terminate the merger agreement at any time prior to closing if the selling shareholders or BioSpin Invest breach any of their respective covenants, representations and warranties, or other agreements contained in the merger agreement and such breach would give rise to the failure of a condition to Bruker BioSciences' obligation to complete the acquisition and such breach is not curable or, if curable, is not cured or waived within 20 calendar days after written notice of such breach has been delivered to the breaching party.

The selling shareholders may terminate the merger agreement at any time prior to closing if Bruker BioSciences breaches any of its covenants, representations and warranties, or other agreements contained in the merger agreement and such breach would give rise to the failure of a condition to the sellers' obligation to complete the acquisition and such breach is not curable or, if curable, is not cured or waived within 20 calendar days after written notice of such breach has been delivered to Bruker BioSciences.

Expenses

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

The Unaudited Pro Forma Condensed Combined Balance Sheet as of September 30, 2007 and Statements of Operations for the nine months ended September 30, 2007 and 2006 and for the years ended December 31, 2006, 2005 and 2004 include the historical consolidated statements of operations of the combined Bruker BioSciences and the Bruker BioSpin Group, giving effect to the acquisitions as if they had occurred on January 1, 2004. This information is only a summary, and you should read it in conjunction with the Bruker BioSciences historical consolidated financial statements and related notes and Management's Discussion and Analysis of Financial Condition and Results of Operations contained in the annual reports, quarterly reports and other information on file with the Securities and Exchange Commission and the Bruker BioSpin Group historical consolidated financial statements and related notes and Management's Discussion and Analysis of Financial Condition and Results of Operations contained elsewhere in this Proxy (see page [93]). See "WHERE YOU CAN FIND MORE INFORMATION" on page [142].

Both Bruker BioSciences and the Bruker BioSpin Group are majority owned by the Bruker BioSpin Group Shareholders. As a result, the acquisition of the Bruker BioSpin Group by Bruker BioSciences is considered a business combination of companies under common control. Accordingly, the acquisition of the Bruker BioSpin Group will be accounted for at historical carrying values.

We have prepared the unaudited pro forma condensed combined financial statements based on available information, using assumptions that we believe are reasonable. For details about the assumptions used, see footnotes 3 and 4 to the unaudited pro forma condensed combined financial statements. These unaudited pro forma condensed combined financial statements are being provided for informational purposes only. They do not purport to represent our actual financial position or results of operations had the merger occurred on the dates specified nor do they project our results of operations or financial position for any future period or date.

The Unaudited Pro Forma Condensed Combined Statements of Operations do not reflect any adjustments for non-recurring items or anticipated operating synergies resulting from the acquisition. Pro forma adjustments are based on certain assumptions and other information that are subject to change as additional information becomes available. Accordingly, the adjustments included in our financial statements published after the completion of the acquisition may vary from the adjustments included in these unaudited pro forma condensed combined financial statements included in this proxy statement.

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

1. Description of Transaction and Basis of Presentation

Under the acquisition agreements, Bruker BioSciences will acquire all of the stock of the companies of the Bruker BioSpin Group. Approximately $388.0 million [(or 42.5% of the purchase price)] will be paid in cash, while the stock component will consist of 57,544,872 shares of Bruker BioSciences shares, which have an aggregate market value of approximately $703.8 million as of December 5, 2007 [(or 57.5% of the purchase price)]. The cash component of the purchase price will be funded from approximately $47.0 million of existing cash, and approximately $341.0 million from a planned senior credit facility. The number of Bruker BioSciences shares to be issued for the stock component of the purchase price was determined by dividing $526.0 million by the trailing average of the Bruker BioSciences closing price per share, as reported in The Wall Street Journal, for the period of ten (10) consecutive trading days ending two (2) trading days prior to the date of the signing of the transaction agreements, which was on December 2, 2007.

The Bruker BioSpin Group Shareholders, who presently own approximately 52% of Bruker BioSciences on an undiluted basis, also own 100% of the stock of the Bruker Biospin Group. This acquisition therefore is a related-party transaction. Pursuant to the acquisition agreements, the transactions are subject to the approval of both a majority of Bruker BioSciences shareholders, and a majority of the non-affiliated Bruker BioSciences shareholders who vote on the transaction. The acquisition agreements were signed among Bruker BioSciences, the Bruker BioSpin Group and all of the Bruker BioSpin Group Shareholders.

The following pro forma adjustments are based on available information and various estimates and assumptions. Actual adjustments will differ from the pro forma adjustments. We believe that these assumptions provide a reasonable basis for presenting the significant effects of the merger and that the pro forma adjustments give appropriate effect to these assumptions and are properly applied in the unaudited pro forma condensed combined financial statements.

The unaudited pro forma statements of operations for the nine months ended September 30, 2007 and 2006 and for the years ended December 31, 2006, 2005 and 2004 combine the historical consolidated statements of operations of Bruker BioSciences and the Bruker BioSpin Group and also reflect the elimination of intercompany transactions, giving effect to the acquisition as if it had occurred on January 1, 2004. The unaudited pro forma condensed consolidated balance sheet gives effect to the acquisition as if it occurred on September 30, 2007.

2. Eliminations in the Combined Balance Sheet and Statements of Operations

The eliminations column in the restated combined financial statements reflects the elimination of all intercompany transactions, which include (in thousands):

(a): Adjustment to eliminate intercompany accounts receivables and payable balances at the end of the period.
(b): Adjustment to eliminate product sales between Bruker BioSciences and the Bruker BioSpin Group during the period presented.
(c): Adjustment to eliminate service sales between Bruker BioSciences and the Bruker BioSpin Group during the period presented.
(d): Adjustment to eliminate product cost of sales between Bruker BioSciences and the Bruker BioSpin Group during the period presented as well as profit in inventory on the balance sheet at the end of each period.

(e): Adjustment to eliminate service cost of sales between Bruker BioSciences and the Bruker BioSpin Group during the period presented as well as profit in inventory on the balance sheet at the end of each period.
(f): Adjustment to record the income tax provision (benefit) associated with the elimination of profit in inventory.
(g): Adjustments to eliminate profit included in inventory, to reduce the income taxes payable associated with the elimination of profit in inventory and to adjust retained earnings for the period for the elimination of profit in inventory.

3. Pro Forma Adjustments to the Unaudited Pro Forma Condensed Consolidated Balance
Sheet

The unaudited pro forma condensed consolidated balance sheet gives effect to the acquisition as if it occurred on September 30, 2007. Pro forma adjustments have been made and are described below (in thousands, except share and per share data)

(a)

The estimated cash to be paid is [42.5%] of the total consideration, or $388 million. We have assumed the following in calculating the pro forma cash adjustment:

i.: The Bruker BioSpin Group Shareholders have elected to receive a combination of cash and stock. The percentage of cash and stock varies for each of the individual shareholders. Since the trailing average of the Bruker BioSciences closing price per share for the period of ten consecutive trading days ending two trading days prior to the signing of the transaction agreements was $9.14, the six shareholders will receive 57,544,872 shares of Bruker BioSciences, with a market value of $703.8 million as of December 5, 2007, and the remainder, $388 million, in cash.
ii.: We anticipate borrowing approximately $351 million under a senior credit facility to partially finance the acquisition of the Bruker BioSpin Group and related expenses, which will increase our long-term debt at the date of the acquisition.

(b)

Adjustment to record an additional draw-down on the anticipated revolving credit facility for estimated acquisition related costs of $10.8 million associated with the transaction. Total acquisition related costs are estimated to be $11.2 million, of which $370,000 and $174,000, respectively, were accrued for on the books of Bruker BioSciences and the Bruker BioSpin Group as of September 30, 2007. Acquisition related costs include investment banking, legal, accounting and antitrust regulation filing fees as well as compensation to be earned by the special committee of the Company's Board of Directors and fees for establishing the senior credit facility. Of the $10.8 million of acquisition related charges referenced above, $2.9 million relates to establishing the senior credit facility, which will be capitalized and amortized over the life of the facility. The remainder of the anticipated acquisition related charges which were not accrued for as of September 30, 2007, or $7.9 million will be expensed as incurred.

(c)

Adjustment to reflect the $0.01 per share par value associated with the 57,544,872 additional shares of Bruker BioSciences common stock to be issued to the Bruker BioSpin Group

Shareholders in connection with the acquisition, less the elimination of the Bruker BioSpin Group common stock par value.

(d): Adjustment to reflect the additional paid in capital associated with the additional shares of Bruker BioSciences common stock to be issued to the Bruker BioSpin Group Shareholders in connection with the acquisition, offset by a deemed dividend to the affiliated shareholders.
(e): Adjustment to establish a valuation allowance for the U.S. deferred tax assets of Bruker BioSpin Group.
(f): Adjustments to reflect the dividend of approximately $66.7 million (75 million Swiss Francs at an exchange rate of $0.89 US Dollars per Swiss Franc as of December 5, 2007) declared by Bruker BioSpin in November 2007, to be paid in December 2007 prior to the consummation of the transaction.

4. Pro Forma Adjustments to the Unaudited Pro Forma Condensed Combined Statements of Operations

The Unaudited Pro Forma Condensed Combined Statements of Operations give effect to the acquisition of the Bruker BioSpin Group as if it occurred on January 1, 2004. Pro forma adjustments have been made and are described below:

(a)

We estimate that Bruker BioSciences will incur merger related costs of $11.2 million related to the acquisition of the Bruker BioSpin Group. These costs include investment banking, legal, accounting and antitrust regulation filing fees as well as compensation to be earned by the special committee of the Company's Board of Directors and fees for establishing the senior credit facility. We will be required to expense all of these costs in the period incurred, except for the costs related to establishing the senior credit facility, which are estimated to be $2.9 million. The costs associated with establishing the senior credit facility will be amortized ratably over the life of the senior credit facility, or five years. During the third quarter of 2007, Bruker BioSciences and the Bruker BioSpin Group in the aggregate incurred $370,000 of these acquisition related costs. These costs were removed as part of the pro forma adjustments as they are material, non-recurring charges directly related to the merger. The merger related costs were not tax effected because Bruker BioSciences was in a net loss position for U.S. tax purposes, the jurisdiction where the expenses were recorded.

(b)

Adjustment reflects the impact of:

•: A reduction of interest income related to the cash on hand of $47 million expected to be used to finance a portion of the acquisition. We estimate that we receive an average interest rate of 3% on cash and short-term investments, which results in a reduction to interest income of $1.4 million on an annual basis and $1.1 million for nine month periods. We have assumed this reduction in interest income would occur primarily in certain German operations, and accordingly, have recorded an associated tax benefit of $564,000 and $423,000, respectively, for the annual and nine month periods.
•: A reduction of interest income related to the dividend of approximately $66.7 million (75 million Swiss Francs at an exchange rate of $0.89 US Dollars per Swiss Franc as of

December 5, 2007). We estimate that we receive an average interest rate of 3% on cash and short-term investments, which results in a reduction to interest income of $2.0 million on an annual basis and $1.5 million for nine month periods. We have assumed this reduction in interest income would occur primarily in certain Swiss operations, and accordingly, have recorded an associated tax benefit of $170,000 and $128,000, respectively, for the annual and nine month periods.

•: An increase in interest expense associated with the anticipated senior credit facility. We expect to borrow approximately $351 million at an average rate of 5.2% to finance a portion of the Bruker BioSpin Group acquisition and to settle certain acquisition related charges, which results in an increase in interest expense of $18.3 million on an annual basis and $13.7 million for nine month periods. The debt is to be incurred in the United States, Switzerland and Germany. The interest on the portion of the debt in the United States has not been tax effected because Bruker BioSciences was in a net loss position for U.S. tax purposes as of the end of each period. We have recorded tax benefits of $3.2 million and $2.4 million, respectively, for the annual and nine month periods for the portion of the debt to be incurred in our Swiss and German subsidiaries.

(c): The change in basic and diluted average shares outstanding reflects the adjustment for the additional shares of Bruker BioSciences common stock to be issued to the Bruker BioSpin Group Shareholders upon consummation of the transaction.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

The discussion and analysis of Bruker BioSpin Group's financial condition and results of operations is based upon Bruker BioSpin Group's consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements requires that Bruker BioSpin Group makes estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting period. On an ongoing basis, Bruker BioSpin Group's management evaluates its estimates and judgments, including those related to revenue recognition, allowance for doubtful accounts, inventories, warranty costs, income taxes and contingencies. Bruker BioSpin Group bases its estimates and judgments on historical experience, current market and economic conditions, its observance of industry trends and other assumptions that Bruker BioSpin Group believes are reasonable and form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results could differ from these estimates.

Bruker BioSpin Group believes the following critical accounting policies to be both those most important to the portrayal of its financial condition and those that require the most subjective judgment.

•: Revenue recognition. The Bruker BioSpin Group recognizes revenue from system sales when persuasive evidence of an arrangement exists, the price is fixed or determinable, title and risk of loss has been transferred to the customer and collectibility of the resulting receivable is reasonably assured. Title and risk of loss is generally transferred to the customer upon receipt of a signed customer acceptance for a system that has been shipped, installed, and for which the customer has been trained. As a result, the timing of customer acceptance or readiness could cause the Bruker BioSpin Group's reported revenues to differ materially from expectations. When products are sold through an independent distributor, a strategic distribution partner or an unconsolidated affiliated distributor, which assumes responsibility for installation, the Bruker BioSpin Group recognizes the system as revenue when the product has been shipped and title and risk of loss has been transferred. The Bruker BioSpin Group's distributors do not have price protection rights or rights to return; however, the Bruker BioSpin Group's products are warranted to be free from defects for a period of one to two years. Revenue is deferred until cash is received when a significant portion of the fee is due over one year after delivery, installation and acceptance of the system. For arrangements with multiple elements, the Bruker BioSpin Group recognizes revenue for each element based on the fair value of the element provided when all other criteria for revenue recognition have been met. The fair value for each element provided in multiple element arrangements is typically determined by referencing historical pricing policies when the element is sold separately. Changes in the Bruker BioSpin Group's ability to establish the fair value for each element in multiple element arrangements could affect the timing of revenue recognition.

Revenue from the sale of accessories and parts is recognized upon shipment and service revenue is recognized as the services are performed.

Other revenues are comprised of research grants and licensing agreements. Grant revenue is recognized as work is performed. Licensing revenue is recognized ratably over the term of the related contract.

•: Warranty costs. Bruker BioSpin Group normally provides a one to two year parts and labor warranty with the purchase of equipment. The anticipated cost for this one to two year warranty is accrued upon recognition of the sale and is included as a current liability on the balance

sheet. Although Bruker BioSpin Group's facilities undergo quality assurance and testing procedures throughout the production process, its warranty obligation is affected by product failure rates, material usage and service delivery costs incurred in correcting a product failure. Although Bruker BioSpin Group's actual warranty costs have historically been consistent with expectations, to the extent warranty claim activity or costs associated with servicing those claims differ from Bruker BioSpin Group's estimates, revisions to the warranty accrual may be required.

•: Inventories. Inventories are stated at the lower of cost or market, with cost determined by the first-in, first-out method. Bruker BioSpin Group maintains an allowance for excess and obsolete inventory to reflect the expected un-saleable or un-refundable inventory based on an evaluation of slow moving products. If ultimate usage or demand varies significantly from expected usage or demand, additional write-downs may be required, resulting in a charge to operations.
•: Allowance for doubtful accounts. Bruker BioSpin Group maintains allowances for doubtful accounts for estimated losses resulting from the inability of its customers to pay amounts due. If the financial condition of Bruker BioSpin Group's customers were to deteriorate, reducing their ability to make payments, additional allowances would be required, resulting in a charge to operations.
•: Income taxes. Bruker BioSpin Group estimates the degree to which tax assets and loss carryforwards will result in a benefit based on expected profitability by tax jurisdiction, and provide a valuation allowance for tax assets and loss carryforwards that Bruker BioSpin Group believes will more likely than not go unused. If it becomes more likely than not that a tax asset or loss carryforward will be used for which a reserve has been provided, Bruker BioSpin Group reverses the related valuation allowance. If Bruker BioSpin Group's actual future taxable income by tax jurisdiction differ from estimates, additional allowances or reversals of reserves may be necessary.

RESULTS OF OPERATIONS

Nine months ended September 30, 2007 compared to the nine months ended September 30, 2006

Revenue

Bruker BioSpin Group's revenues were $351.9 million for the nine months ended September 30, 2007 compared to $313.5 million for the nine months ended September 30, 2006. The increase from prior year results is $38.4 million or 12.2%. Excluding the effect of foreign exchange, revenue would have increased by $16.4 million, or 5.2%. Revenue growth was driven by strong customer demand for our magnetic resonance systems. Included in other revenue for the nine months ended September 30, 2007 and September 30, 2006 are license revenues and grant revenues from various research and development projects funded primarily by European government authorities amounting to $1.9 million and $1.7 million, respectively.

Cost of Revenue

Bruker BioSpin Group's cost of product revenue for the nine months ended September 30, 2007 increased $29.0 million, or 16.0%, to $210.0 million compared to $181.0 million for the same period in 2006. The cost of product revenue as a percentage of product revenues was 60.0% for the nine months ended September 30, 2007 compared to 58.1% for the same period in 2006. The increase in cost of product revenue as a percentage of product revenues is primarily due to a change in product mix.

Sales and Marketing

Bruker BioSpin Group's marketing and sales expense for the nine months ended September 30, 2007 increased $2.4 million, or 7.2%, to $35.9 million compared to $33.5 million for the same period in

2006. Marketing and sales expenses as a percentage of net revenues were 10.2% for the nine months ended September 30, 2007 and 10.7% for the same period in 2006. The decrease in sales and marketing expense as a percentage of product and service revenue is primarily attributable to increased revenue in the first nine months ended September 30, 2007 as compared to the first nine months ended September 30, 2006.

General and Administrative

Bruker BioSpin Group's general and administrative expenses for the nine months ended September 30, 2007 increased $2.1 million, or 12.5%, to $18.9 million compared to $16.8 million for the same period in 2006. General and administrative expenses as a percentage of net revenues were consistent at 5.4% for the nine months ended September 30, 2007 and 2006.

Research and Development

Bruker BioSpin Group's research and development expenses for the nine months ended September 30, 2007 decreased $0.7 million, or (1.8%) to $38.2 million compared to $38.9 million for the same period in 2006. As a percentage of net revenues, research and development expenses were 10.9% for the nine months ended September 30, 2007 compared to 12.4% for the same period in 2006. The decrease in research and development expenses as a percentage of product and service revenue is driven by increased revenues and a reduction in materials usage for research and development projects.

Interest and Other Income (Expense), Net

Interest and other income, net for the nine months ended September 30, 2007 was $5.4 million compared to $2.7 million for the same period in 2006. During the nine months ended September 30, 2007, the major components within interest and other income, net, were interest income of $7.6 million and gains on foreign currency transactions of $0.8 million, offset by miscellaneous expenses of $3.0 million. During the nine months ended September 30, 2006, the major components within interest and other income, net, were interest income of $3.7 million and gains on foreign currency transactions of $1.5 million, offset by miscellaneous expenses of $2.5 million.

Provision for Income Taxes

The income tax provision for the nine months ended September 30, 2007 was $10.7 million compared to an income tax provision of $15.5 million for the nine months ended September 30, 2006, representing effective tax rates of 19.7% and 33.7%, respectively. Our effective tax rate is calculated using our projected annual pre-tax income or loss, and is affected by the expected level of tax benefits, and changes in the mix of our pre-tax income and losses among jurisdictions with varying statutory tax rates.

On August 14, 2007, the German Business Tax Reform 2008 was signed by the Federal President and the legislative process was finalized on August 17, 2007 with the official publication of the law. This new legislation changes the German Federal Corporate Tax Rate from 25% to 15%. In addition, German Trade Tax is no longer deductible from the Corporate Income Tax. Bruker BioSpin Group has analyzed the impact of these changes on its deferred tax assets and liabilities as of the date of enactment. The deferred tax items that will reverse after December 31, 2007 have been adjusted to reflect the new tax rate which will become effective on January 1, 2008. As a result, Bruker BioSpin Group has recorded a net reduction to income tax expense of $5.8 million in the nine months ending September 30, 2007.

In July 2006, the Financial Accounting Standards Board issued FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes-an interpretation of FASB Statement 109 ("FIN 48"). Among other things, FIN 48 provides guidance to address uncertainty in tax positions and clarifies the accounting for income taxes by prescribing a minimum recognition threshold which income tax

positions must achieve before being recognized in the financial statements. In addition, FIN 48 requires expanded annual disclosures, including a roll forward of the beginning and ending aggregate unrecognized tax benefits as well as specific detail related to tax uncertainties for which it is reasonably possible the amount of unrecognized tax benefit will significantly increase or decrease within twelve months. Bruker BioSpin Group adopted FIN 48 on January 1, 2007, and recorded a reduction of retained earnings of $1.2 million effective January 1, 2007. Bruker BioSpin Group has unrecognized tax benefits of approximately $6.8 million as of January 1, 2007, which, if recognized, would result in a reduction of the Bruker BioSpin Group's effective tax rate. As of January 1, 2007, Bruker BioSpin Group does not expect any material changes to unrecognized tax positions within the next twelve months.

Bruker BioSpin Group recognizes penalties and interest related to unrecognized tax benefits in the provision for income taxes. As of September 30, 2007, we had approximately $1.2 million of accrued interest and penalties related to uncertain tax positions included in the liability on the consolidated balance sheet, of which approximately $0.3 million was recorded during the nine months ended September 30, 2007.

The tax years 2003 to 2006 are open tax years for most of our major taxing jurisdictions. Bruker BioSpin Group files returns in many foreign and state jurisdictions with varying statutes of limitations.

The effect of foreign exchange was minimal. Included in other revenue for the years ended December 31, 2006 and December 31, 2005 are license revenues and grant revenues from various research and development projects funded primarily by European government authorities amounting to $3.2 million and $4.8 million, respectively. Also included in other revenue for the year ended December 31, 2005 was income generated from a customer cancellation of a system order in the amount of $1.6 million.

Cost of Product Revenue

Bruker BioSpin Group's cost of product revenue for the year ended December 31, 2006 decreased $6.7 million, or (2.6%), to $246.3 million compared to $253.0 million for the same period in 2005. The cost of product revenue as a percentage of product revenues was 55.5% for the year ended December 31, 2006 compared to 57.7% for the same period in 2005. The decrease in cost of product revenues as a percentage of product revenues was primarily attributed to cost reductions in our superconducting wire business, and other restructuring program initiatives taken in 2005.

Marketing and Sales

Bruker BioSpin Group's marketing and sales expense for the year ended December 31, 2006 increased $3.7 million, or 8.2%, to $48.9 million compared to $45.2 million for the same period in 2005. Marketing and sales expenses as a percentage of net revenues were 10.9% for the year ended December 31, 2006 and 10.2% for the same period in 2005. The increase in sales and marketing expense as a percentage of product and service revenue is primarily attributed to an increase in commissions.

Research and Development.

Bruker BioSpin Group's research and development expenses for the year ended December 31, 2006 decreased $1.5 million, or (2.7%) to $53.7 million compared to $55.2 million for the same period in 2005. As a percentage of net revenues, research and development expenses were 12.0% for the year ended December 31, 2006 compared to 12.4% for the same period in 2005. The primary decrease in research and development expenses can be attributed to employee reductions in some of our manufacturing facilities.

General and Administrative

Bruker BioSpin Group's general and administrative expenses for the year ended December 31, 2006 decreased $2.5 million, or (10.5%), to $21.3 million compared to $23.8 million for the same period in 2005. General and administrative expenses as a percentage of net revenues were 4.8% for the year ended December 31, 2006 and 5.3% for the same period in 2005. The primary reason for the decrease in general and administrative expenses can be attributed to the cost reduction programs put in place in 2005 in an effort to reduce costs and improve productivity.

Special Credit

During 2005, a settlement agreement was signed for our various magnet patent litigation cases, which released Bruker BioSpin Group from any losses. As a result, this liability was reversed in the amount of $25.8 million during 2005.

Interest and Other Income, Net

Interest and other income, net for the year ended December 31, 2006 was $1.0 million compared to $8.0 million for the same period in 2005. During the year ended December 31, 2006, the major components within interest and other income, net, were interest income of $5.5 million and miscellaneous income of $0.2 million, offset by losses on foreign currency transactions of $4.7 million. During the year ended December 31, 2005, the major components within interest and other income, net, were interest income of $2.4 million, gains on foreign currency transactions of $4.8 million, and miscellaneous income of $0.8 million.

Provision for Income Taxes

The income tax provision for the year ended December 31, 2006 was $21.1 million compared to an income tax provision of $26.6 million for the year ended December 31, 2005, representing effective tax rates of 27.2% and 26.1%, respectively. The increase in our effective tax rate is primarily due to a change in the mix of our pre-tax income and losses among jurisdictions with varying statutory tax rates.

Twelve Months Ended December 31, 2005 Compared to Twelve Months Ended December 31, 2004

Revenues

Bruker BioSpin Group's revenues were $445.2 million for the year ended December 31, 2005 compared to $487.3 million for the year ended December 31, 2004. The decline from prior year results is $42.1 million or (8.6%). The effect of foreign exchange was minimal. The decrease in product revenues can primarily be attributed to the weakened global demand for magnetic resonance systems. Included in other revenue for the years ended December 31, 2005 and December 31, 2004 are license revenues and grant revenues from various research and development projects funded primarily by European government authorities amounting to $4.8 million and $2.9 million, respectively. Also included in other revenue for the year ended December 31, 2005 was income generated from a customer cancellation of a system order in the amount of $1.6 million.

Cost of Product Revenues

Bruker BioSpin Group's cost of product revenue for the year ended December 31, 2005 decreased $35.2 million, or (12.2%), to $253.0 million compared to $288.2 million for the same period in 2004. The cost of product revenue as a percentage of product revenues was 57.7% for the year ended December 31, 2005 compared to 59.5% for the same period in 2004. The decrease in overall cost of product revenue as a percentage of product revenues is primarily attributed to a change in product mix and a reduction in our write-down of demonstration inventory to net realizable value. The write-down

of demonstration inventory to net realizable value was $12.3 million in 2005 compared to $14.4 million in 2004.

Marketing and Sales

Bruker BioSpin Group's marketing and sales expense for the year ended December 31, 2005 decreased $3.1 million, or (6.4%), to $45.2 million compared to $48.3 million for the same period in 2004. Marketing and sales expenses as a percentage of net revenues were 10.2% for the year ended December 31, 2005 and 9.9% for the same period in 2004. The decrease in our sales and marketing expenses is attributed to the lower variable costs incurred due to lower sales volume generated in 2005 compared to 2004.

Research and Development

Bruker BioSpin Group's research and development expenses for the year ended December 31, 2005 increased $1.3 million, or 2.4% to $55.2 million compared to $53.9 million for the same period in 2004. As a percentage of net revenues, research and development expenses were 12.4% for the year ended December 31, 2005 compared to 11.1% for the same period in 2004. The increase in research and development expenses can be attributed to additional research and development spending in our Switzerland operations compared to prior year.

General and Administrative

Bruker BioSpin Group's general and administrative expenses for the year ended December 31, 2005 decreased $2.6 million, or (9.8%), to $23.8 million compared to $26.4 million for the same period in 2004. General and administrative expenses as a percentage of net revenues were 5.3% for the twelve months ended December 31, 2005 and 5.4% for the same period in 2004.

Other Special Charges (Credit)

During 2004, Bruker BioSpin Group recorded a charge of $28.5 million to cover costs associated with potential assessments and related legal fees associated with a patent lawsuit, to the extent such amounts were deemed probable and estimable. During 2005, a settlement agreement was signed for our various magnet patent litigation cases, which released Bruker BioSpin Group from any losses. As a result, this liability was reversed in 2005 in the amount of $25.8 million.

Interest and Other Income (Expense), Net

Interest and other income (expense), net for the year ended December 31, 2005 was $8.0 million compared to ($6.8) million for the same period in 2004. During the year ended December 31, 2005, the major components within interest and other income, net, were interest income of $2.4 million, gains on foreign currency transactions of $4.8 million, and miscellaneous income of $0.8 million. During the year ended December 31, 2004, the major components within interest and other expense, net, were losses on foreign currency transactions of $7.8 million, offset by interest income of $0.2 million, and other miscellaneous income of $0.8 million.

Provision for Income Taxes

The income tax provision for the year ended December 31, 2005 was $26.6 million compared to $11.7 million for the year ended December 31, 2004. The effective tax rate was 26.1% for the year ended December 31, 2005 compared to 33.2% for 2004. Our effective tax rate decreased due to changes in the mix of our pre-tax income and losses among jurisdictions with varying statutory tax rates.

LIQUIDITY AND CAPITAL RESOURCES

As of September 31, 2007 and December 31, 2006, Bruker BioSpin Group had cash and cash equivalents of $268.8 million and $259.1 million, respectively. Bruker BioSpin Group currently anticipates that its existing cash and short-term investments will be sufficient to support Bruker BioSpin Group's operating and investing needs for at least the next twelve months, but this depends on our profitability and our ability to manage working capital requirements. Historically, Bruker BioSpin Group has financed its growth through a combination of cash provided from operations and debt financing.

During the year ended December 31, 2006, net cash provided by operating activities was $45.1 million compared to $98.7 million during the year ended December 31, 2005. The decrease in cash provided by operating activities was primarily attributable to a decrease in customer deposits and a decrease in our income taxes payable. During the nine months ended September 30, 2007, net cash provided by operating activities was $43.0 million compared to $8.2 million during the nine months ended September 30, 2006. The increase in cash provided by operating activities was primarily attributable to improved earnings, an increase in our customer deposits, an increase in income taxes payable, and an increase in accrued expenses.

During the year ended December 31, 2006, net cash used in investing activities was $17.0 million compared to $7.8 million during the year ended December 31, 2005. Cash used in investing activities during the year ended December 31, 2006 consisted primarily of $13.4 million of capital expenditures for machinery and equipment used in production. Additionally, Bruker BioSpin Group invested $3.5 million in short-term investments and $1.6 million for the acquisition of various technology from ShapeMetal Innovations during the year ended December 31, 2006. Cash used in investing activities during the year ended December 31, 2005 consisted primarily of $14.6 million in capital expenditures for purchases of machinery and equipment used in production. This was offset with cash provided by investing activities of $2.3 million in property and equipment sales, $2.4 million in collection on notes receivable from affiliated companies, and $2.1 million in proceeds from short-term investments. During the nine months ended September 30, 2007, net cash used in investing activities was $4.0 million compared to $8.4 million during the nine months ended September 30, 2006. Cash used in investing activities for the nine months ended September 30, 2007 related primarily to capital investments amounting to $6.5 million offset by cash proceeds from short-term investments of $2.5 million. Cash used in investing activities for the nine months ended September 30, 2006 related primarily to capital investments amounting to $4.1 million and $3.7 million in purchases of short-term investments. Bruker BioSpin Group invests in capital equipment used in production facilities on a continuing basis in order to enhance the efficiency of our operations.

During the year ended December 31, 2006, financing activities used $40.3 million of cash compared to $48.6 million of cash during the year ended December 31, 2005. The use of cash consisted of dividend payments in the amount of $29.5 million and $33.6 million, and debt repayments of $10.8 million and $15.0 million in 2006 and 2005, respectively. During the nine months ended September 30, 2007, financing activities used $46.4 million of cash compared to $32.9 million during the nine months ended September 30, 2006. The increased use of cash during the nine months ended September 30, 2007 was related to an increase in dividend payments and an increase in debt repayments.

As of September 30, 2007, Bruker BioSpin Group had $5.8 million in term loans outstanding compared to $9.5 million at December 31, 2006. The interest rate on the term loans ranged from 3.94% to 4.1% at both September 30, 2007 and December 31, 2006.

The following table summarizes future principal payments on borrowings under long-term debt outstanding as of December 31, 2006 (in thousands):

Contractual Obligations (in thousands)	Total		Less than 1 Year		1-3 Years		4-5 Years		More than 5 years
Short-term borrowings	$	—	$	—	$	—	$	—	$	—
Operating lease obligations	$	6,766	$	1,865	$	2,039	$	1,349	$	1,513
Long-term debt	$	9,465	$	5,333	$	4,132	$	—	$	—
Total contractual cash obligations	$	—	$	—	$	—	$	—	$	—

At this time, the Bruker BioSpin Group can not make a reliable estimate as to the timing of the cash settlements associated with the unrecognized tax benefits in accordance with FIN48. The total unrecognized tax benefits are $6.8 million as of September 30, 2007.

Bruker BioSpin Group leases a building under an agreement that is classified as a capital lease. The cost of the building under capital lease is included in the combined balance sheets as property, plant and equipment and was $4,880 and $4,382 at December 31, 2006 and December 31, 2005, respectively. Accumulated amortization of the leased building at December 31, 2006 and December 31, 2005 was approximately $877 and $613, respectively.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Bruker BioSpin Group is potentially exposed to market risk associated with changes in foreign exchange and interest rates for which it selectively used financial instruments to reduce related market risks. An instrument is treated as a hedge if it is effective in offsetting the impact of volatility in our underlying exposure. Bruker BioSpin Group has also entered into instruments which are not effective derivatives under the requirements of SFAS No. 133, and therefore such instruments are not designated as hedges. All transactions are authorized and executed pursuant to its policies and procedures. Analytical techniques used to manage and monitor foreign exchange and interest rate risk include market valuations and sensitivity analysis.

Impact of Foreign Currencies

Bruker BioSpin Group sells products in many countries, and a substantial portion of revenue and expenses are denominated in foreign currencies, principally in the Euro and Swiss Franc. Fluctuations in the rate of exchange between the U.S. dollar and foreign currencies could adversely affect its financial results. Costs related to these sales are largely denominated in the same respective currencies, thereby limiting its transaction risk exposure. However, for sales not denominated in U.S. dollars, if there is an increase in the rate at which a foreign currency is exchanged for U.S. dollars, it will require more of the foreign currency to equal a specified amount of U.S. dollars than before the rate increase. In such cases, if Bruker BioSpin prices its products in the foreign currency, it will receive less in U.S. dollars than it did before the rate increase went into effect. If Bruker BioSpin prices its products in U.S. dollars and competitors price their products in local currency, an increase in the relative strength of the U.S. dollar could result in its prices not being competitive in a market where business is transacted in the local currency.

Bruker BioSpin Group may from time to time enter into forward currency exchange contracts. Specifically, as of December 31, 2005 and December 31, 2004, it had contracts with notional amounts aggregating $71.5 million and $10.0 million, respectively. These contracts do not qualify for hedge accounting under SFAS No. 133. Accordingly, the instruments are marked-to-market with the corresponding gains and losses recorded in other expense in the current period. The realized and unrealized gains and (losses) under these contracts for the years ended December 31, 2005 and 2004, were $(7.2) million and $0.7 million, respectively. No such contracts existed as of December 31, 2006 and September 30, 2007.

Bruker BioSpin Group has entered into foreign-denominated debt obligations for debt related to its European production facilities. The currency effects of the debt obligations are reflected in interest and other income (expense), net, on the consolidated statement of operations.

Impact of Interest Rates

Bruker BioSpin Group's exposure related to adverse movements in interest rates is derived primarily from outstanding floating rate debt instruments that are indexed to short-term market rates and cash equivalents. Its objective in managing its exposure to interest rates is to decrease the volatility that changes in interest rates might have on its earnings and cash flows. To achieve this objective, Bruker BioSpin Group uses a fixed rate agreement to adjust a portion of its debt that is subject to variable interest rates.

A 10% increase or decrease in the average cost of Bruker BioSpin Group's variable rate debt would not result in a material change in pre-tax interest expense.

Inflation

Bruker BioSpin Group does not believe inflation had a material impact on its business or operating results during any of the periods presented.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Review, Approval or Ratification of Transactions with Related Persons

All transactions with related parties in excess of $50,000 are reviewed and pre-approved in accordance with our Audit Committee Charter and written procedures. Our Audit Committee, which is ultimately responsible for approving related party transactions, pre-approves such transactions involving amounts exceeding $500,000. The Audit Committee has delegated authority to the Chief Financial Officer and Corporate Controller to review and pre-approve all related party transactions, including distribution, shared administrative services and sales and purchasing activities, involving amounts from $50,000 to $500,000. A related party transaction will be approved only if it is determined upon review that the transaction is in the best interests of our company, and at fair market value and at arm's length conditions. If the transaction involves a director, that director will be recused from all discussions and decisions about the transaction. In considering the transaction, the executive officer or the committee, as appropriate, will consider all relevant factors, including as applicable:

•: the business purpose for the transaction;
•: quantifying the amount and volume of transactions to assess materiality;
•: methods used to establish the terms of the transaction and whether the transaction is on arm's-length terms comparable to those available to third parties; and
•: the overall fairness of the transaction to the company.

Typically every quarter, management reviews with the Audit Committee all related party transactions, including those the committee was not required to pre-approve. This review consists of a memorandum summarizing the information described above with respect to all related party transactions entered into in the preceding quarter, and is followed up on during one of the telephonic or in-person meeting between the Audit Committee and management.

107

Name

Pursuant to the terms of the Sharing Agreement, Bruker BioSpin GmbH and Bruker Physik have granted to the other parties to the Sharing Agreement a perpetual, irrevocable, non-exclusive, royalty-free, non-transferable right and license to use the name "Bruker" in connection with the conduct and operation of their respective businesses, provided that the parties do not materially interfere with any other party's use of the name, do not take any action which would materially detract from the goodwill associated with the name and do not take any action which would cause a lien to be placed on the name or the parties' license rights. This license automatically becomes null and void with respect to a party if that party files, or has filed against it, a petition in bankruptcy, fails to comply with the relevant terms of the Sharing Agreement or suffers a major loss of its reputation in its industry or the marketplace.

Intellectual Property

The parties to the Sharing Agreement also generally share technology and other intellectual property rights, as they existed on or prior to February 28, 2000, subject to the terms of the Sharing Agreement. In addition, under the Sharing Agreement each party has agreed to negotiate with any other party who wishes to obtain an agreement permitting such party to make a broader use of the first party's intellectual property that was in effect on or prior to February 28, 2000. However, no party has any obligation to enter into these agreements.

Distribution

In various countries in which we do not have our own distribution network, we share in the worldwide distribution network of the Bruker BioSpin Group. The Sharing Agreement provides for the use of common distribution channels by the parties to the agreement. The Sharing Agreement states that the terms and conditions of sale and the transfer pricing for any shared distribution will be on an arm's length basis as would be utilized in typical transaction with a person or entity not a party to the agreement. The Sharing Agreement also states that no common sales channel may have any exclusivity in any country or geographic area.

Services

Bruker BioSciences also shares various general and administrative expenses for items such as umbrella insurance policies, retirement plans, accounting services and leases, with various Bruker BioSpin Group companies. The Sharing Agreement provides that these services are charged among the affiliated companies at arm's length conditions and pricing, according to individual Sub-Sharing Agreements. In 2006, various Bruker BioSpin Group companies provided administrative and other services (including office space) to Bruker BioSciences at a cost of approximately $3.7 million.

Purchases and Sales

Bruker BioSciences purchases subunits or components, including some components used in its CBRN (chemical, biological, radiological and nuclear) detection products, miscellaneous electronics boards used in Fourier transform mass spectrometers, sheet metal cabinets and some of the superconducting magnets used for Fourier transform mass spectrometers, and a low-temperature attachment for certain x-ray systems, from various Bruker BioSpin Group companies, at arm's length commercial conditions and pricing. In 2006, Bruker BioSciences purchased components from these affiliates for $19.4 million.

Under the Sharing Agreement, the affiliated companies who supply certain of these subunits or components have agreed to continue to do so for at least seven years and to provide spare parts for at least 12 years from the date of the Sharing Agreement, at the terms and conditions and prices in effect

108

on the date of the Sharing Agreement, which may be increased annually in an amount proportional to annual increases in the Consumer Price Index. The Sharing Agreement states that the terms and conditions of purchases of subunits and components shall be at reasonable arm's length terms and conditions and that pricing shall be competitive. In 2006, Bruker BioSciences purchases from Bruker BioSpin Group companies were approximately 4% of revenues.

Bruker BioSciences supplies system products and individual licenses to its HyStar software package to Bruker BioSpin Group companies at what Bruker BioSciences believes to be commercially reasonable arm's length conditions and pricing. As part of the Sharing Agreement, Bruker BioSciences guarantees a continued supply of the HyStar software package (or its successor) for at least seven years.

Bruker BioSciences may, from time to time, distribute the products of Bruker BioSpin Group companies as part of customer orders.

Bruker BioSciences supplies a variety of products to Bruker BioSpin Group companies for resale at what Bruker BioSciences believes to be commercially reasonable arm's length conditions and pricing. For the year ended December 31, 2006, Bruker BioSciences sold products to Bruker BioSpin Group companies in the amount of $10.8 million. However, these sales were primarily for resale of certain products by Bruker BioSpin Group entities as described above.

Additional Agreements, Collaborations and Sales

Bruker BioSciences recognized sales to the Bruker BioSpin Group of approximately $10.8 million in 2006, and purchases from the Bruker BioSpin Group of approximately $19.4 million in 2006.

Bruker BioSciences is a party to certain collaborations with various affiliates, including:

DESCRIPTION OF BRUKER BIOSCIENCES CAPITAL STOCK

All shares issued to the Bruker BioSpin Group Shareholders upon consummation of the transactions will have the same rights as our common stock currently outstanding.

Bruker BioSciences' authorized capital stock consists of 200,000,000 shares of common stock, par value $.01 per share, and 5,000,000 shares of preferred stock, par value $.01 per share. Holders of Bruker BioSciences common stock have no preemptive, subscription or redemption rights.

110

PROPOSAL NO. 4: APPROVAL OF THE CHARTER AMENDMENT TO INCREASE OUR
AUTHORIZED SHARES.

The fourth proposal asks stockholders to approve an amendment to Bruker BioSciences' certificate of incorporation to increase the number of authorized shares that may be issued by our company. This amendment will only be adopted if the transactions discussed earlier in this proxy statement are consummated.

General. The board of directors of Bruker BioSciences has resolved to amend the certificate of incorporation of Bruker BioSciences to increase the total number of shares of common stock which Bruker BioSciences shall have authority to issue from 200,000,000 shares of common stock, par value $.01 per share, to 260,000,000 shares of common stock, par value $.01 per share, in the event the acquisitions are consummated. The board of directors of Bruker BioSciences has directed that the proposal be submitted for action at a special meeting of stockholders. The affirmative vote of at least a majority of shares of common stock entitled to vote at the Special Meeting is required to approve the this amendment. If the stockholders approve the amendment to the certificate of incorporation to increase the authorized capital stock of the company, the amendment will be effective upon the filing of the certificate of amendment of certificate of incorporation with the Secretary of State of the State of Delaware. The text of the proposed amendment is included in this proxy statements in Annex C.

Prior to Amendment. Pursuant to Bruker BioSciences' certificate of incorporation as amended by the certificate of merger filed with the Secretary of State of the State of Delaware on July 1, 2003, and as further amended on June 29, 2006, the authorized capital stock of Bruker BioSciences consists of (i) 200,000,000 shares of common stock, par value $0.01 per share, and (ii) 5,000,000 shares of preferred stock, par value $0.01 per share. As of December 5, 2007, there were 105,545,527 shares of common stock issued and outstanding and no shares held in treasury. As of December 5, 2007, there were no shares of preferred stock issued and outstanding.

After Amendment. If the stockholders approve this contingent amendment, following the filing of the certificate of amendment, the authorized capital stock of Bruker BioSciences will consist of (i) 260,000,000 shares of common stock, par value $0.01 per share, and (ii) 5,000,000 shares of preferred stock, par value $0.01 per share.

Increase in Number of Shares of Common Stock. If approved by the stockholders, this amendment will authorize Bruker BioSciences to issue an additional 60,000,000 shares of Bruker BioSciences' common stock at any time after the consummation of the proposed acquisitions. The board of directors is empowered under the certificate of incorporation to issue shares of authorized stock without further stockholder approval.

Rationale for the Proposed Amendment. As of December 5, 2007 there were 86,454,473 shares of Bruker BioSciences' common stock available for issuance and not otherwise reserved. If the acquisitions are consummated, 57,544,872 shares of Bruker BioSciences common stock will be issued to the Bruker BioSpin Group stockholders. This amendment to the Bruker BioSciences certificate of incorporation is not required in order to issue shares of Bruker BioSciences common stock in connection with the transactions. However, the board of directors believes that the number of authorized shares of common stock should be increased by 60,000,000 to provide sufficient shares for use for corporate purposes as may be deemed advisable by the board of directors, without further action or authorization by the stockholders. The corporate purposes might include attaining capital funds through the sale of stock, acquiring other corporations or properties, or declaring stock dividends in the nature of a stock split. There are no current plans, agreements, arrangements, or understandings to issue any of the shares of common stock which would be authorized by the amendment; however, the board of directors believes that the availability of shares would afford Bruker BioSciences flexibility in considering and implementing any of the corporate transactions enumerated above.

111

Possible Effects of the Amendment. If the stockholders approve the amendment, Bruker BioSciences will have additional authorized but unissued shares of common stock that may be issued without further action or authorization of the stockholders (except as required by law or the rules of NASDAQ or any other stock exchange on which Bruker BioSciences' securities may then be listed). The issuance of additional shares of common stock may have a dilutive effect on earnings per share. In addition, the issuance of additional shares of common stock could have a dilutive effect on the voting power of the current stockholders because they do not have preemptive rights.

Appraisal Rights in Respect of the Proposed Amendment. Bruker BioSciences' stockholders have no appraisal rights with respect to the proposed amendment.

Contingent Amendment. This amendment is to be effective only if the transactions involving the Bruker BioSpin Group described in this proxy statement are consummated. If the transactions are not consummated, then Bruker BioSciences will not amend its certificate of incorporation to increase the number of shares of common stock authorized for issuance.

RECOMMENDATION OF THE BRUKER BIOSCIENCES BOARD OF DIRECTORS

THE BOARD OF DIRECTORS OF BRUKER BIOSCIENCES RECOMMENDS A VOTE FOR THE AMENDMENT TO THE BRUKER BIOSCIENCES CERTIFICATE OF INCORPORATION TO INCREASE THE AUTHORIZED CAPITAL STOCK OF THE COMPANY IF THE ACQUISITIONS ARE CONSUMMATED.

112

PROPOSAL NO. 5: APPROVAL OF AN AMENDMENT TO THE STOCK OPTION PLAN TO
INCREASE THE NUMBER OF AUTHORIZED SHARES.

The fifth proposal asks stockholders to approve an amendment to the Bruker BioSciences amended and restated stock option plan to increase the number of shares of common stock for which options may be granted.

In February 2000, the board of directors and stockholders of Bruker Daltonics approved and adopted Bruker Daltonics' 2000 Stock Option Plan, authorizing Bruker Daltonics to issue options to purchase a total of 2,220,000 shares of common stock. Upon the consummation of the merger of Bruker Daltonics and Bruker AXS in 2006, the Bruker Daltonics stock option plan became the Bruker BioSciences Amended and Restated 2000 Stock Option Plan. In connection with the merger of Bruker BioSciences and Bruker Optics, the board of directors and stockholders of Bruker BioSciences approved the increase of the Bruker BioSciences option pool by 1,680,000 shares such that a total of 8,000,000 shares were reserved for issuance pursuant to the stock option plan. As of December 31, 2006, options to purchase 4,299,625 shares of common stock and no shares of restricted common stock were outstanding under the stock option plan, leaving 3,700,375 shares available for grant.

Accordingly, the board of directors of Bruker BioSciences determined that it was in the best interest of Bruker BioSciences to amend its option plan to increase its option pool by 2,000,000 shares such that a total of 10,000,000 shares are reserved for issuance pursuant to the stock option plan. This total of 10,000,000 includes the 4,299,625 options to purchase shares of Bruker BioSciences common stock that were outstanding on December 31, 2006. The increase in the Bruker BioSciences option pool is not necessary for the consummation of the acquisition; but, whether or not the acquisition is consummated, the board of directors believes the increase is necessary to continue to provide long-term incentives to attract and retain employees. The affirmative vote of a majority of the shares of Bruker BioSciences common stock present or represented and entitled to vote at the Special Meeting will be required to approve this amendment to the stock option plan.

RECOMMENDATION OF THE BRUKER BIOSCIENCES BOARD OF DIRECTORS

THE BOARD OF DIRECTORS OF BRUKER BIOSCIENCES RECOMMENDS A VOTE "FOR" THE AMENDMENT TO THE AMENDED AND RESTATED OPTION PLAN TO INCREASE THE NUMBER SHARES OF COMMON STOCK FOR WHICH OPTIONS MAY BE GRANTED.

BRUKER BIOSCIENCES AMENDED AND RESTATED 2000 STOCK OPTION PLAN

The following description of certain features of the Bruker BioSciences stock option plan is intended to be a summary only. The summary is qualified in its entirety by the full text of the Bruker BioSciences stock option plan, which is attached as Annex D to this proxy statement and which incorporates the provisions of the proposed stock option plan amendments.

General. The Bruker BioSciences stock option plan provides for the granting of incentive stock options to Bruker BioSciences employees and non-qualified options, as defined in Section 422 of the Internal Revenue Code, to Bruker BioSciences employees, directors, advisors and consultants. The Bruker BioSciences stock option plan may be administered by the board of directors of Bruker BioSciences or by the Bruker BioSciences compensation committee.

(a): interpret and apply the stock option plan; and
(b): determine the eligibility of an individual to participate in the stock option plan.

Eligibility. Eligible participants under the stock option plan include officers, employees, consultants, advisors and directors of Bruker BioSciences. Incentive stock options may only be granted

to employees of Bruker BioSciences or any subsidiary. In determining a person's eligibility to be granted an option, and the number of shares to be granted to any person, the compensation committee takes into account, in its sole discretion, the person's position and responsibilities, the nature and value to Bruker BioSciences or its subsidiaries of the person's service and accomplishments, the person's present and potential contribution to the success of Bruker BioSciences or its subsidiaries, and such other factors as the compensation committee deems relevant. No option designated as an incentive stock option may be granted to any employee who owns, immediately prior to the grant of the option, stock representing more than 10% of the total combined voting power of all classes of stock of Bruker BioSciences or a parent or a subsidiary, unless the purchase price of the stock under the option is at least 110% of its fair market value at the time the option is granted and the option, by its terms, is not exercisable more than five years from the date it is granted.

Terms and provisions of options. Stock options are granted under stock option agreements which contain the vesting schedules of the stock options. Non-qualified stock options are granted with an exercise price of at least 50% of fair market value of the common stock on the date of grant, and incentive stock options are granted with an exercise price of at least 100% of the stock's fair market value on the date of grant. Vested options may be exercised in full at one time or in part from time to time in amounts of 50 shares or more. The payment of the exercise price may be made as determined by the board or committee and set forth in the option agreement, by delivery of cash or check, by tendering shares of common stock (provided that payment by this means will not cause Bruker BioSciences to recognize for financial accounting purposes a charge to earnings) or by means of a broker-assisted cashless exercise. Bruker BioSciences may delay the issuance of shares covered by the exercise of an option until the shares for which the option has been exercised have been registered or qualified under the applicable federal or state securities laws or until Bruker BioSciences' counsel has opined that the shares are exempt from the registration requirements of applicable federal or state securities laws. The term of any option granted under the stock option plan is limited to either five or ten years, depending on the nature of the option holder. Unvested options generally terminate immediately upon the termination of an option holder's employment with Bruker BioSciences, but in no event will unvested options terminate more than 90 days after an option holder leaves Bruker BioSciences' employ. Options granted under the stock option plan are not transferable other than by will or the laws of descent and distribution. The compensation committee may grant up to 20% of the shares reserved for option grants as restricted stock rather than as stock options.

Recapitalization; reorganization; change of control. The stock option plan provides that proportionate adjustments shall be made to the number of authorized shares which may be granted under the stock option plan and as to which outstanding options, or portions of outstanding options, then unexercised shall be exercisable as a result of increases or decreases in Bruker BioSciences' outstanding shares of common stock due to reorganization, merger, consolidation, recapitalization, stock split-up, combination of shares, or dividends payable in capital stock, such that the proportionate interest of the option holder shall be maintained as before the occurrence of such event. Upon the sale or conveyance to another entity of all or substantially all of the property and assets of Bruker BioSciences, including by way of a merger or consolidation or a change in control of the company, as defined in the stock option plan, the board of directors of Bruker BioSciences shall have the power and the right to accelerate the exercisability of any options. Additionally, the compensation committee may, in its discretion, accelerate the exercisability of any option subject to such terms and conditions as the compensation committee deems necessary and appropriate.

Termination or amendment. Unless sooner terminated by the board of directors, the stock option plan will terminate on February 11, 2010, ten years from the date on which the stock option plan was adopted by the Bruker BioSciences board of directors. The board of directors may, at any time, terminate the stock option plan. All options granted under the stock option plan shall terminate upon the dissolution or liquidation of Bruker BioSciences; provided, however, that each option holder (if at

114

such time in the employ of or otherwise associated with Bruker BioSciences or any of its subsidiaries) shall have the right, immediately prior to the dissolution or liquidation, to exercise his or her option to the extent then exercisable. The board of directors of Bruker BioSciences may modify or amend the option at any time but may not, however, without the approval of the stockholders increase the maximum number of shares for which options may be granted, change the designation of the class of persons eligible to receive options under the stock option plan or make any other changes to the stock option plan which require stockholder approval under applicable law or regulation.

Tax effects of stock option plan participation. Options granted under the stock option plan are intended to be either incentive stock options, or an ISO, as defined in section 422 of the Code, or non-qualified stock options. The following discussion applies to options that are granted with an exercise price of at least 100% of the stock's fair market value on the date of grant, so that special tax rules under Internal Revenue Code Section 409A relating to nonqualified deferred compensation do not apply.

Incentive Stock Options. Except as provided below with respect to the alternative minimum tax, the option holder will not recognize taxable income upon the grant or exercise of an ISO. In addition, if the option holder holds the shares received pursuant to the exercise of the option for more than one year after the date of transfer of stock to the option holder upon exercise of the option and for more than two years after the option is granted, the option holder will recognize long-term capital gain or loss upon the disposition of the stock measured by the difference between the option exercise price and the amount received for such shares upon disposition. If the option holder disposes of the stock prior to the expiration of the required holding periods at a price equal to or in excess of the fair market value of the stock on the date of exercise, then the option holder will recognize ordinary income in the year of the sale equal to the difference between the fair market value of the stock at the date of exercise and the exercise price. In this event, the option holder will also recognize a capital gain (long-term or short-term, depending upon the holding period of the stock) equal to the difference between the sales price and the fair market value of the stock on the date of exercise. If the option holder disposes of the stock prior to the expiration of the required holding periods at a price that is less than the fair market value of the stock on the date of exercise (but greater than the exercise price), the option holder will recognize ordinary income in the year of the sale equal to the difference between the sales price and the exercise price. If the option holder disposes of the stock prior to the expiration of the required holding periods at a price below the exercise price, the option holder will incur a capital loss (long-term or short-term, depending upon the holding period of the stock).

In addition to regular tax consequences, an option holder may have alternative minimum tax consequences when he exercises an ISO. Generally speaking, individual taxpayers are required each year to pay the greater of their regular tax liability or their alternative minimum tax liability. For alternative minimum tax purposes, the excess of the fair market value of the underlying stock on the date of exercise over the exercise price of the option is included in alternative minimum taxable income for the year of exercise. The net amount of alternative minimum tax income (after taking into account any applicable exemptions) is multiplied by the applicable alternative minimum tax rate to determine alternative minimum tax liability income. If an option holder owes alternative minimum tax for the year of exercise of an ISO, the optionee may be entitled to a tax credit for all or part of the excess of the amount of the option holder's alternative minimum tax liability over his regular tax liability for that year. Any credit may be applied directly against the option holder's tax liability in later years in which the option holder's regular tax liability exceeds the option holder's alternative minimum tax liability, but only to the extent of the excess. Any balance of the alternative minimum tax credit would carry forward and may be used in subsequent years subject to the limitations previously described. If the option holder engages in a disqualifying disposition of an ISO in the same calendar year as the exercise of the option, the option holder essentially avoids the effects of alternative minimum tax with respect to the option. Bruker BioSciences will not be allowed an income tax deduction upon the grant or exercise of

115

an ISO. Upon a disqualifying disposition of shares by the option holder acquired by exercise of the ISO, Bruker BioSciences generally will be allowed a deduction in an amount equal to the ordinary income recognized by the option holder.

Non-Qualified Stock Options. As in the case of ISOs, generally no income is recognized by the option holder on the grant of a non-qualified stock option. On the exercise by an option holder of a non-qualified stock option, the excess of the fair market value of the stock when the option is exercised over the exercise price will be (a) taxable to the option holder as ordinary income, and (b) generally deductible for income tax purposes by Bruker BioSciences. The option holder's tax basis in his stock will equal his cost for the stock plus the amount of ordinary income he had to recognize with respect to the non-qualified stock option. Accordingly, upon a subsequent disposition of stock acquired upon the exercise of a non-qualified stock option, the option holder will recognize short-term or long-term capital gain or loss, depending upon the holding period of the stock, equal to the difference between the amount realized upon disposition of the stock by the option holder and his basis in the stock.

New Plan Benefits. It is not possible to state the persons who will receive options or awards under the stock option plan in the future, nor the amount of options or awards which will be granted thereunder.

The following table sets forth certain information with respect to Bruker BioSciences' equity compensation plans for the fiscal year ended December 31, 2006.

RECOMMENDATION OF THE BRUKER BIOSCIENCES BOARD OF DIRECTORS

THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE FOR PROPOSAL NO. 6, TO CHANGE OUR NAME TO "BRUKER CORPORATION."

117

PROPOSAL NO. 7: THE ELECTION OF DIRECTORS

The seventh proposal on the agenda for the Special Meeting is the election of Dirk D. Laukien to serve as a Class II director and Tony Keller to serve as a Class III director, each for a term beginning at the Special Meeting and ending at our 2008 and 2009 Annual Meetings of Stockholders, respectively, or until a successor has been duly elected and qualified. Our amended and restated certificate of incorporation provides that the board of directors shall consist of three classes of directors with overlapping three-year terms. One class of directors is to be elected each year for a three-year term. Directors are assigned to each class in accordance with a resolution or resolutions adopted by the board of directors, each class consisting, as nearly as possible, of one-third the total number of directors. There are currently eleven members of the board of directors, consisting of four Class I directors, four Class II directors and three Class III directors.

In December 2007, the Board of Directors voted to expand the size of the board to thirteen, the number of Class II directors to five and the number of Class III directors to four. At the Special Meeting, one nominee will be elected as a Class II director for a term expiring at the 2008 Annual Meeting of Stockholders and one nominee will be elected to serve as a Class III director to serve for a term expiring at the 2009 Annual Meeting of Stockholders. The directors in Class I are serving terms expiring at our Annual Meeting of Stockholders in 2010.

Both Tony Keller and Dirk D. Laukien are new nominees. All nominees were approved by our board of directors, including a majority of our independent directors.

Unless marked otherwise, proxies received will be voted FOR the election of each of the two nominees specified below. If any such nominee for the office of director is unwilling or unable to serve as a nominee for the office of director at the time of the Special Meeting, the proxies may be voted either (1) for a substitute nominee who shall be designated by the present board of directors to fill such vacancy or (2) for the other nominees only, leaving a vacancy. Alternatively, the size of the board of directors may be reduced so that there is no vacancy. The board of directors has no reason to believe that any of the nominees will be unwilling or unable to serve if elected as a director.

BOARD MEETINGS, COMMITTEES AND COMPENSATION

There are currently eleven members of our board of directors. Seven of the current members of the board of directors, namely, Collin J. D'Silva, Richard D. Kniss, Daniel S. Dross, William A. Linton, Brenda J. Furlong, Richard A. Packer and Wolf-Dieter Emmerich are independent within the meaning of the Marketplace Rules of the NASDAQ Stock Market LLC, or NASDAQ.

During fiscal year 2006, our board of directors held fifteen meetings and acted by written consent two times. During such periods in 2006 in which they served as board members, all of the directors attended at least 75% of the aggregate of: (1) the total number of meetings of the board of directors and (2) the total number of meetings held by committees of the board of directors on which they served. It is the policy of our board of directors that at least two directors, including at least one independent director, attend our Annual Meeting, either in person or by telephonic conference. Three directors attended our 2006 Annual Meeting. As described below, the board of directors has an Audit Committee and a Compensation Committee. The board of directors does not have a Nominating Committee, but all nominations require approval by a majority of independent directors..

Audit Committee. The Audit Committee of the board of directors, which is currently comprised of Brenda J. Furlong, Collin J. D'Silva and Richard A. Packer, each of whom satisfy the applicable independence requirements of the SEC rules and regulations and NASDAQ Marketplace Rules, met nine times during the 2006 fiscal year. The board of directors has determined that Brenda J. Furlong, Chair of the Audit Committee, qualifies as an audit committee financial expert pursuant to applicable SEC rules and regulations.

The Audit Committee provides assistance to the board of directors in fulfilling its legal and fiduciary obligations with respect to matters involving the accounting, auditing, financial reporting and internal control functions of our company and its subsidiaries. The Audit Committee works extensively with the independent auditors, pre-approves all audit and non-audit services provided to our company by its independent auditors, reviews the performance of the independent auditors and replaces or terminates the independent auditors when circumstances warrant. The Audit Committee is also charged with establishing and monitoring procedures for (i) the receipt, retention or treatment of complaints received by our company regarding accounting, internal accounting controls or auditing matters, and (ii) the confidential submission by our employees of concerns regarding questionable accounting or auditing matters. None of the members of the Audit Committee, or the proposed members of the Audit Committee, have participated in the preparation of any financial statements of the our company at any time during the last three fiscal years.

Compensation Committee. The Compensation Committee, which is comprised of Daniel S. Dross, Richard D. Kniss and William A. Linton, all of whom meet the independence requirements of the NASDAQ Marketplace Rules, met three times during the 2006 fiscal year and acted by written consent two times during the 2006 fiscal year. Mr. Linton is the Chairman of the Compensation Committee. The Compensation Committee administers our stock option plan, determines the chief executive officer's salary, bonus, and equity based compensation, oversees the executive compensation program for our other executive officers and determines such compensation, reviews general policy matters relating to compensation and employee benefits and makes recommendations concerning these matters to the board of directors. From time to time, we expect that various of our senior executive officers will provide analysis and recommendations to the Compensation Committee on compensation issues, as requested by the Compensation Committee. In particular, the Chief Executive Officer annually evaluates the performance of the Chief Financial Officer and the Senior Vice President and makes recommendations to the Compensation Committee regarding the compensation of these executive officers. The Compensation Committee reviews these performance evaluations and recommendations and, if the Committee deems appropriate, adopts the recommendations with little to no change. In addition, going forward, it is expected that the Chief Financial Officer will do the same with respect to

122

the Controller. For 2006, the Chief Financial Officer set the compensation of the Controller. Our Chief Executive Officer, Chief Financial Officer and the Director of Human Resources may routinely attend meetings of the Compensation Committee to provide information relating to matters the Compensation Committee is considering. The Compensation Committee may, from time to time, meet in executive session without any executive officers present. In December 2006, the Compensation Committee approved the charter included as Annex E to this proxy statement.

123

COMPENSATION OF DIRECTORS

We pay the non-employee directors of the board a mix of cash and share-based compensation based on the determination of the Compensation Committee. Employee directors receive compensation only as employees of Bruker BioSciences. Directors are reimbursed for reasonable out-of-pocket expenses incurred in attending meetings of the board or committees thereof.

The following table provides information concerning the compensation paid by Bruker BioSciences to each of the non-employee directors for the fiscal year ended December 31, 2006.

Effective August 1, 2006, the Compensation Committee voted to increase non-employee director compensation after consideration of a survey of director compensation at comparable public companies prepared for the committee at the request of certain independent directors, and a comparison of the survey results to our director compensation practices established in 2003. During 2006, the cash compensation for non-employee directors was set as follows:

FULL-YEAR FEE

	In effect January 1, 2006 to July 31, 2006		In effect August 1, 2006 to December 31, 2006		TOTAL RETAINER FOR THE YEAR ENDED DECEMBER 31, 2006
Annual Retainer:

During 2006, William Linton, M. Christopher Canavan, Jr., Taylor Crouch and Daniel Dross served as members of a temporary special committee of the board of directors established in January 2006 to represent the interests of the stockholders of Bruker BioSciences unaffiliated with the Laukien family in connection with the potential acquisition of Bruker Optics. In accordance with the terms of the Compensation and Indemnification Agreement entered into on April 18, 2006 by the members of the special committee and Bruker BioSciences, the Chair of the special committee, William Linton, received a $70,000 fee for his services as Chair of the special committee, and each of the remaining members of the special committee received a $60,000 fee for their services on the special committee.

On January 5, 2006, Bruker BioSciences granted each non-employee director, other than Mr. Stein, either an option to purchase 6,000 shares of common stock or 2,000 shares of restricted common stock. Based on differences in the tax treatment of awards of options and common stock, directors who are United States citizens are awarded shares of restricted stock, while directors who are not United States citizens receive grants in the form of options. The option and restricted stock grants vest in equal annual installments over three years on the anniversary of the grant date, beginning on January 5, 2007. Such share-based awards are made annually to non-employee directors as a component of their compensation. On February 28, 2007, the board of directors approved an award of either an option to purchase 6,000 shares of common stock or 2,000 shares of restricted common stock to all non-employee directors able to hold such awards in their own name.

126

DIRECTOR NOMINATIONS

We do not have a nominating committee, based on a board determination that full board participation in the nominations process would foster improved corporate governance. On March 3, 2004, our company adopted a policy by board resolution governing the nomination of directors, according to which the full board of directors approves all nominees for board membership. In some cases, one or more board members may screen potential nominees before presenting them to the full board for consideration. In all cases, a majority of our independent directors must approve the nominees. The qualifications of recommended candidates will be reviewed by at least a majority of the independent directors of our company, as well as the full board of directors. Stockholders may recommend director candidates for inclusion by the board of directors in the slate of nominees which the board recommends to stockholders for election as described below.

The process followed by the board and independent directors to identify and evaluate potential candidates includes requests to board members and others for recommendations, meetings from time to time to evaluate biographical information and background material relating to potential candidates and interviews of selected candidates by independent directors and the board. The independent directors and the board are authorized to retain advisers and consultants and to compensate them for their services. The independent directors and the board did not retain any such advisers or consultants for this purpose during fiscal year 2006.

In considering whether to recommend any candidate for inclusion in the board's slate of recommended director nominees, the board and the independent directors apply the criteria which are set forth in a resolution of the board approved and adopted on March 3, 2004.

These criteria include, but are not limited to, the following:

•: experience in aspects of business or technology relevant to our company's business;
•: sufficient time available to devote to the affairs of our company;
•: character and integrity;
•: ability to represent the best interests of stockholders as a whole rather than special interest groups;
•: willingness to participate actively as a board member; and
•: communication, decision-making and interpersonal skills.

The board and the independent directors may also consider the following for some of the director nominees:

•: experience serving as a director of a public company;
•: familiarity with corporate governance issues;
•: independence, as determined in accordance with SEC rules and regulations and NASDAQ listing standards;
•: experience in running a comparable company or division of a comparable company;
•: insight into our company, including our strategy, business model, operations, and financials;
•: knowledge of industry trends and markets; and
•: qualification as an "audit committee financial expert" to serve on the Audit Committee in accordance with SEC and NASDAQ definitions.

127

The board and the independent directors do not assign specific weights to particular criteria and no particular criterion is necessarily applicable to all prospective nominees. We believe that the backgrounds and qualifications of the directors, considered as a group, should provide a significant composite mix of experience, knowledge and abilities that will allow the board to fulfill its responsibilities.

Although our company does not have a specific policy with respect to the nomination of directors by stockholders, our company will consider nominations made by stockholders. We believe that it is not necessary to have a policy for director nominations by stockholders because the board of directors, including the independent directors, is able to effectively locate and evaluate potential candidates for nomination to the board of directors due to the directors' intimate knowledge of our company and the life science industry. However, stockholders may communicate directly with the board of directors by written communication submitted to Richard M. Stein at the address set forth below under "Stockholder Communications." Mr. Stein shall be primarily responsible for monitoring the communications and providing summaries or copies of such communications to the board of directors as he deems appropriate, and, as described below, will submit communications to the board of directors relating to corporate governance matters and long-term corporate strategy. Stockholders may use this process to suggest potential nominations to the board of directors. Such suggested nominations shall be forwarded to the board of directors and the proposed candidates shall be evaluated using substantially the same process and applying the same criteria as used and applied in evaluating candidates submitted by board members. Nominations shall be received by our company within the timeframe set forth herein under "Time for Submission of Stockholder Proposals."

COMPENSATION DISCUSSION AND ANALYSIS

Overview

Our company's executive compensation program is administered by the Compensation Committee of the board of directors. Pursuant to the authority delegated by the board of directors, the Compensation Committee oversees our company's stock option plan, determines the chief executive officer's salary, bonus, and equity-based compensation, oversees the executive compensation program for our other executive officers, including reviewing and approving the overall values and forms of compensation for the executive officers listed in the 2006 Summary Compensation Table below (the "Named Executive Officers") as well as for other officers of our company, reviews general policy matters relating to compensation and employee benefits and makes recommendations concerning these matters to the board of directors.

Executive Compensation Philosophy

Our key objectives in structuring and determining executive compensation are to:

•: attract and retain qualified executive officers;
•: motivate existing officers to perform;
•: reward outstanding corporate performance;
•: align compensation with Bruker BioSciences' annual and long-term performance goals;
•: enhance our profitability; and
•: maximize stockholder value.

Our company achieves these objectives through a compensation philosophy that seeks to align compensation with our strategic objectives and reward our Named Executive Officers for meeting certain performance goals. Executive compensation is based in part on a pay-for-performance philosophy, which emphasizes both company and individual performance measures that correlate closely with the achievement of both short and long term performance objectives. To motivate our Named Executive Officers, we focus on cash compensation, a portion of which is tied to the individual's performance, and we augment this compensation annually with equity grants. In structuring executive compensation, the Compensation Committee focuses on our goal of long-term enhancement of stockholder value by using stock based incentive programs with extended vesting schedules. We believe the use of such incentives to retain and motivate individuals who have developed the skills and expertise required to lead Bruker BioSciences is key to our continued success.

Components of Executive Compensation

Compensation is comprised of cash compensation in the form of annual base salary and annual incentive bonus awards, as well as long-term incentive compensation in the form of stock options and restricted stock grants.

Annual Base Salary. Base salaries are determined based on a variety of factors, including the officers' levels of responsibility, experience and potential, and a comparison of salaries paid to peers within the company and to those with similar roles at other companies. Base salaries are set at levels that the Compensation Committee believes will allow our company to attract and retain superior managers who will enable our company to deliver on its business goals. The Compensation Committee considers cash compensation data derived from an independent source, Salary.com's CompAnalyst Executive, for a peer group of publicly-traded companies in the same or similar industries and targets cash compensation for our executive officers within the median range of this peer group. The peer group includes Affymetrix Inc., Agilent Technologies, Inc., Caliper Life Sciences, Inc., Ciphergen

129

Biosystems, Inc., Dionex Corporation., Keithley Instruments Inc., Molecular Devices Corporation, PerkinElmer, Inc., Sequenom, Inc., Thermo Fisher Scientific Inc., Waters Corporation and Varian, Inc. Base salaries are reviewed annually and may be adjusted after considering the various factors described above. The Chief Executive Officer makes recommendations to the Compensation Committee for base salaries for the Chief Financial Officer and the Senior Vice President. When setting the base salaries of these executive officers, the Compensation Committee, while considering the recommendations of the Chief Executive Officer, makes the final determination based on the factors listed above and the executive officer's performance during the previous year. The Compensation Committee also evaluates the performance of and sets the salary for the Chief Executive Officer.

Annual Cash Incentive Awards. Annual incentive awards in the form of performance-based cash bonuses for the Chief Executive Officer and Bruker BioSciences' other executive officers are based upon management's success in meeting Bruker BioSciences' financial and strategic goals. Historically, specific criteria for these bonuses have been determined based on a combination of qualitative and quantitative measures, the details of which are established each year. These goals vary for each executive based on his responsibilities and role within our company and may include financial or strategic measures, including, among others, revenue growth, gross profit margin improvement, meeting earnings per share targets, identifying and developing new product and market opportunities and other strategic initiatives. The goals are intended to require performance which results in our company meeting or exceeding its financial goals. These cash incentive bonus awards reflect the individual's performance compared with his performance goals for the year, as well as the overall performance of our company. In 2006, between 70% and 80% of the bonus potential for executive officers was based on the achievement of company-wide goals and between 20% and 30% of the bonus potential was based on the achievement of goals specifically set for each officer. In 2006, bonuses for our company's Named Executive Officers ranged from 25% to 54.5% of base salary.

The Chief Executive Officer makes recommendations to the Compensation Committee for our company-wide performance goals and the bonus goals and weighting for the Chief Financial Officer and the Senior Vice President. The Chief Executive Officer also provides the Committee with his assessment of the performance of each of these executives against the respective bonus goals and proposed bonus payout. When determining the bonus structure and goals and the bonus payout for these executive officers, the Compensation Committee, while considering the recommendations of the Chief Executive Officer, makes the final determination based on the executive officer's performance, and that of the department which he led during the year relative to the performance-based goals. The determination of the bonus earned is generally made within the first two months after the end of the fiscal year, allowing time to assess the achievement of the bonus goals. On occasion, additional bonuses in excess of those calculated to have been earned have been given by the Compensation Committee in recognition of exceptional performance. As described below, in 2006, the Chief Financial Officer set the compensation of the Controller. Going forward, it is expected that the Chief Financial Officer will recommend performance and bonus goals, including their respective weightings, for the Controller, and be responsible for making a recommendation to the Compensation Committee regarding the compensation of the Controller based on his assessment of the Controller's performance against these goals.

Long-Term Incentives. Incentive compensation in the form of stock options and restricted stock is designed to provide long-term incentives to executive officers and other employees, to encourage the executive officers and other employees to remain with Bruker BioSciences and to enable recipients to develop and maintain a long-term stock ownership position in the common stock, which in turn motivates the recipient to focus on long-term enhancement in stockholder value. Bruker BioSciences' Amended and Restated 2000 Stock Option Plan, administered by the Compensation Committee, is the vehicle for the granting of stock options and restricted stock. Prior to 2005, incentive stock options and non-qualified stock options were the only form of equity compensation granted. The Board and the

130

Compensation Committee selected this form of equity compensation because it aligned the interests of employees to those of the stockholders and also because of accounting and tax treatments of such awards. Beginning in 2006, the accounting treatment for stock options changed as a result of Statement of Financial Accounting Standards No. 123(R) and, in 2006, the Compensation Committee began granting U.S. employees shares of restricted stock. Our company evaluates the efficacy of its long-term incentive compensation on an ongoing basis, and may from time to time provide input and recommendations to the Compensation Committee with regard to the optimal form and extent of equity incentives to be granted to employees, including the Named Executive Officers.

While generally granted on an annual basis, all options and restricted stock grants are discretionary and may be granted by the Compensation Committee at any time. Our company does not embrace performance-vesting, meaning that individual vesting is not based upon the achievement of any specific goals or objectives. The Compensation Committee does, however, consider the individual and company's performance in determining the total and individual equity awards. The Compensation Committee determined that equity compensation awards to executives and all other employees should be based upon the economic value of the grant award and should be considered part of the overall targeted compensation. In making specific grants to executives, the Compensation Committee evaluates each executive officer's total equity compensation package. The Compensation Committee generally reviews the option and restricted stock holdings of each of the executive officers, including vesting and exercise price and the then current value of such options or restricted stock. We consider equity compensation to be an integral part of a competitive executive compensation package, a way to reinforce the individual's commitment to Bruker BioSciences and an important mechanism to align the interests of management with those of Bruker BioSciences' stockholders. Annual grants are generally made in January or February of each year.

Chief Executive Officer Compensation

Annual Base Salary. Dr. Frank Laukien's base salary, which is subject to annual review and increase by the Compensation Committee, was $295,000 for the year ended December 31, 2006. The Compensation Committee has set Frank Laukien's base salary for 2007 at $306,800.

Annual Cash Incentive Award. The amount of Frank Laukien's bonus is determined annually by the Compensation Committee. Frank Laukien's target bonus pool was $150,000 for 2006. The formula for determining the amount of Frank Laukien's bonus for 2006 included a mix of quantitative factors, which represented 70% of his bonus potential, and qualitative factors, which represented 30% of his bonus potential. Quantitative factors included, among others, revenue growth, gross profit margin improvement, achieving an increase in earnings per share and reducing the working capital ratio. Qualitative factors included, among other things, developing the senior management teams of Bruker BioSciences, Bruker AXS and Bruker Daltonics, implementing a formal review process for Bruker BioSciences' senior management, identifying and developing new market and new product opportunities, and developing and implementing a three-year strategic plan for Bruker BioSciences. Frank Laukien's bonus for the fiscal year ended December 31, 2006 was determined by the Compensation Committee to be $250,000, including 100% of the $150,000 target amount based on Frank Laukien's achievement of target objectives, and an additional $100,000 for outstanding performance in excess of plan. The Compensation Committee has not established a specific set of performance targets for 2007.

Long-Term Incentives. During 2006, Frank Laukien was granted 33,250 shares of restricted common stock under the Amended and Restated 2000 Stock Option Plan. The shares granted to Frank Laukien vest annually over five years, with twenty percent vesting each year on the anniversary of the grant. Through his ownership of our common stock and options to purchase common stock, Frank Laukien's pecuniary interests are closely aligned with those of our stockholders.

131

Other Named Executive Officer Compensation

William J. Knight

Mr. Knight's base salary for 2006 was $250,000, with a bonus target of $60,000. The formula for determining the amount of Mr. Knight's bonus is determined annually by the Compensation Committee and each year his performance and Bruker BioSciences' performance are measured against pre-established goals. The formula for determining the amount of Mr. Knight's bonus for the fiscal year ended December 31, 2006 was based on a mix of quantitative factors, which represented 70% of his bonus potential, and qualitative factors, which represented 30% of his bonus potential. Quantitative factors considered included, among others, revenue growth, gross profit margin improvement, achieving an increase in earnings per share and reducing the working capital ratio. Qualitative factors included, among other things, the successful integration of financial reporting functions of Bruker Optics and growth in cash flows leading to corresponding debt reduction. Mr. Knight's bonus for the fiscal year ended December 31, 2006 was determined by the Compensation Committee to be $100,000, including 100% of the $60,000 target amount based on Mr. Knight's achievement of target objectives, and an additional $40,000 for outstanding performance in excess of plan. The Compensation Committee has set Mr. Knight's base salary for 2007 at $260,000 and approved a 2007 bonus target of $85,000.

During 2006, Mr. Knight was granted 8,350 shares of restricted common stock under the Amended and Restated 2000 Stock Option Plan. The shares granted to Mr. Knight vest annually over five years, with twenty percent vesting each year on the anniversary of the grant.

Dirk D. Laukien

Dr. Dirk Laukien joined Bruker BioSciences as its Senior Vice President in July 2006, in connection with the acquisition of Bruker Optics. Following the acquisition of Bruker Optics, our company set Dirk Laukien's annual base salary at $250,000. Of this $250,000 annual base salary, the Company paid Dirk Laukien $125,000 for his services from July 1, 2006 through December 31, 2006. The Compensation Committee has set Dirk Laukien's base salary for 2007 at $260,000. Dirk Laukien also received a $2.5 million one-time success fee payment from Bruker Optics immediately prior to the closing of our acquisition of Bruker Optics. The Compensation Committee has not established a specific set of performance targets for Dirk Laukien's 2007 annual cash incentive award.

In connection with the acquisition of Bruker Optics, Dirk Laukien was awarded 500,000 shares of restricted common stock under the Amended and Restated 2000 Stock Option Plan. The shares granted to Dirk Laukien vest annually over five years, with twenty percent vesting each year on the anniversary of the grant.

Brian P. Monahan

Mr. Monahan's base salary for 2006 was $165,000, with a bonus target of $35,000. The formula for determining the amount of Mr. Monahan's bonus has historically been determined annually by the Chief Financial Officer and each year Mr. Monahan's performance and the performance of Bruker BioSciences and Bruker Daltonics are measured against pre-established goals. The formula for determining the amount of Mr. Monahan's bonus for the fiscal year ended December 31, 2006 was based on a mix of quantitative factors, which represented 80% of his bonus potential, and qualitative factors, which represented 20% of his bonus potential. Quantitative factors were weighted evenly against the performance of Bruker BioSciences and Bruker Daltonics and included, among others, revenue growth, gross profit margin improvement, achieving an increase in earnings per share and reducing the working capital ratio. Qualitative factors included, among other things, the successful implementation of a new integrated accounting system and a reduction in our company's financial closing cycle. Mr. Monahan's bonus for the fiscal year ended December 31, 2006 was determined by the Chief Financial Officer to be $41,472, including 100% of the $35,000 target amount based on

132

Mr. Monahan's achievement of target objectives, and an additional $6,472 for outstanding performance in excess of plan. Mr. Monahan's base salary for 2007 has been set at $180,000. In recommending Mr. Monahan's base salary, the Chief Financial Officer reviewed salaries paid to executives in comparable positions at our U.S. subsidiaries and affiliates. The increase in Mr. Monahan's salary also reflects his promotion to Executive Vice President of Bruker Daltonics. The Chief Financial Officer has recommended and the Compensation Committee has approved a 2007 bonus target for Mr. Monahan of $30,000.

During 2006, Mr. Monahan was granted 5,000 shares of restricted common stock under the Amended and Restated 2000 Stock Option Plan. The shares granted to Mr. Monahan vest annually over five years, with twenty percent vesting each year on the anniversary of the grant.

Executive Benefits

In 2006, our Named Executive Officers were eligible for the same level and offering of benefits made available to other employees, including our company's 401(k) plan and welfare benefit programs.

Employment Contracts, Termination of Employment and Change in Control Arrangements

Although Bruker BioSciences does not currently have an employment agreement with any of its executive officers, it did issue a letter offering employment to William J. Knight, our Chief Financial Officer. Under the terms of the offer letter, Mr. Knight is entitled to a continuation of salary and benefits for a period of three months in the event his employment is terminated within twelve months of a sale of all or substantially all of our business to a third party.

Under the terms of the awards of options and restricted common stock under the Amended and Restated 2000 Stock Option Plan, unvested amounts are forfeited if the grantee's employment or business relationship with our company is terminated for any reason, other than in the event of death or disability. The board of directors does, however, have the power and the right to accelerate vesting of any and all unvested amounts in the event of a change in control of Bruker BioSciences.

Section 162(m) Limitations

Section 162(m) of the U.S. Internal Revenue Code limits the tax deductibility by a corporation of compensation in excess of $1,000,000 paid to the Chief Executive Officer and any other of its four most highly compensated executive officers. However, compensation which qualifies as "performance based" is excluded from the $1,000,000 limit if, among other requirements, the compensation is payable only upon attainment of pre-established, objective performance goals under a plan approved by stockholders.

The Compensation Committee does not presently expect total cash compensation payable for salaries to exceed the $1,000,000 limit for any individual executive. Having considered the requirements of Section 162(m), the Compensation Committee believes that stock option grants to date meet the requirement that such grants be "performance based" and are, therefore, exempt from the limitations on deductibility. The Compensation Committee will continue to monitor the compensation levels potentially payable under Bruker BioSciences' cash compensation programs, but intends to retain the flexibility necessary to provide total cash compensation in line with competitive practice, our compensation philosophy and Bruker BioSciences' best interests.

133

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Securities Exchange Act of 1934 and the rules promulgated thereunder require Bruker BioSciences' officers and directors and persons owning more than 10% of the outstanding common stock of Bruker BioSciences to file reports of ownership and changes in ownership with the Securities and Exchange Commission and to furnish us with copies of all these filings. We believe, based solely upon a review of (i) those reports and amendments thereto furnished to us during and with respect to our fiscal year ended December 31, 2006, and (ii) written representations from reporting persons, that all of our directors and executive officers complied with the reporting requirements of Section 16(a) of the Exchange Act during fiscal 2006.

STOCKHOLDER COMMUNICATIONS

The board will give appropriate attention to written communications that are submitted by stockholders, and will respond if and as appropriate. Absent unusual circumstances or as contemplated by committee charters and subject to any required assistance or advice from legal counsel, Richard M. Stein, Secretary of our company, is primarily responsible for monitoring communications from stockholders and for providing copies or summaries of such communications to the other directors as he considers appropriate.

Communications are forwarded to all directors if they relate to important substantive matters and include suggestions or comments that Mr. Stein considers to be important for the directors to know. In general, communications relating to corporate governance and long-term corporate strategy are more likely to be forwarded than communications relating to ordinary business affairs, personal grievances and matters as to which we may receive repetitive or duplicative communications.

Stockholders who wish to send communications on any topic to the board should address such communications to Richard M. Stein, Secretary, at Nixon Peabody LLP, 100 Summer Street, Boston, MA 02110.

TIME FOR SUBMISSION OF STOCKHOLDER PROPOSALS

Pursuant to Rule 14a-8 under the Exchange Act, stockholders may present proper proposals for inclusion in a company's proxy statement and for consideration at the next Annual Meeting of its stockholders by submitting their proposals to Bruker BioSciences in a timely manner.

Stockholders interested in submitting a proposal for inclusion in the proxy materials for the Annual Meeting of Stockholders in 2008 may do so by following the procedures set forth in Rule 14a-8 of the Securities Exchange Act of 1934, as amended. To be eligible for inclusion, stockholder proposals must have been received by Bruker BioSciences no later than November 30, 2007.

Additionally, under our by-laws, no business may be brought before an Annual Meeting unless it is specified in the notice of meeting by or at the direction of the board or by a stockholder entitled to vote who has delivered notice to Bruker BioSciences (containing certain information specified in the by-laws) not less than 90 or more than 120 days prior to the first anniversary of the preceding year's Annual Meeting.

OTHER MATTERS

Management knows of no matters which may properly be and are likely to be brought before the meeting other than the matters discussed herein. However, if any other matters properly come before the meeting, the persons named in the enclosed proxy will vote in accordance with their best judgment.

Report of Independent Auditors

The Shareholders
Bruker BioSpin Group

We have audited the accompanying combined balance sheets as of December 31, 2006 and 2005, of the companies listed in Note 1, and the related combined statements of income, shareholders' equity and cash flows for each of the three years in the period ended December 31, 2006. These financial statements are the responsibility of the companies' management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. We were not engaged to perform an audit of the companies' internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the companies' internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the combined financial position at December 31, 2006 and 2005, of the companies listed in Note 1, and the combined results of their operations and their cash flows for each of the three years in the period ended December 31, 2006 in conformity with U.S. generally accepted accounting principles.

As discussed in Notes 2 and 17 to the combined financial statements, in 2006 the companies adopted Statement of Financial Accounting Standards ("SFAS") No. 158, Employers Accounting for Defined Benefit Pension and Other Postretirement Plans—an amendment of FASB Statements No. 87, 88, 106 and 132(R).

Bruker BioSpin Group

Notes to Combined Financial Statements

1. Description of Business and Basis of Presentation

These financial statements present the combined financial position of Bruker BioSpin Inc., Bruker Physik AG, Techneon AG, Bruker BioSpin Invest AG and all of their wholly owned subsidiaries (the Bruker BioSpin Group or the Group). These companies represent companies under the control of common shareholders. All significant inter-group accounts and transactions have been eliminated in the combined financial statements. The combined financial statements have been prepared in accordance with U.S. generally accepted accounting principles.

The Bruker BioSpin Group designs, manufactures and distributes enabling life science tools based on its core technology, magnetic resonance. The Group's core technology platforms are Nuclear Magnetic Resonance (NMR), Electro Paramagnetic Resonance (EPR), Magnetic Resonance Imaging (MRI), bench-top NMR and EPR, as well as advanced magnet technology and power supplies. Bruker's NMR division is a worldwide leader in NMR spectroscopy, with design, manufacturing and application centers in Europe, North America and Japan, as well as application and customer support facilities in most industrialized and developing countries. The Group also sells and services non-core products that are manufactured by non-combined Bruker-affiliated entities. The Group's diverse customer base includes pharmaceutical companies, biotechnology companies, academic institutions and government agencies.

Effective July 1, 2003, the Group acquired the operations of a superconducting wire manufacturer, European Advanced Superconductors (EAS) GmbH & Co KG in Hanau, Germany. The superconducting wire manufacturer is also a wire supplier to the Group's magnet manufacturing sites. In March 2004, the Group acquired certain assets of ZFW, Gottingen, through a newly formed Bruker subsidiary, European High Temperature Superconductors (EHTS) GmbH & Co. KG. This entity provides research and development of high temperature superconductors.

2. Summary of Significant Accounting Policies

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities, at the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Actual results could differ from such estimates.

Cash and Cash Equivalents

The Group considers all highly liquid investments with original maturities of 90 days or less at date of purchase to be cash equivalents. Certain of these investments represent deposits which are not insured by the FDIC or any other United States government agency. Cash and cash equivalents are carried at cost, which approximates fair market value.

Restricted Cash

At December 31, 2006 and 2005, the Group had $4,095 and $5,931, respectively, that was subject to restrictions in connection with advance deposits made by customers and bank performance-bid bonds. According to the terms of the various agreements, $3,791 of these funds will be released from restrictions within one year. The remaining $304 will be released at the discretion of certain

F-7

government agencies and is designated as a long-term asset in the accompanying combined balance sheet at December 31, 2006.

Short-Term Investments

The Group accounts for its short-term investments in accordance with Statement of Financial Accounting Standards (SFAS) No. 115, Accounting for Certain Investments in Debt and Equity Securities. The Group's investments consist of money market funds that are considered to be available-for-sale and bond instruments that are considered to be trading securities at December 31, 2006 and 2005. The available-for-sale securities are reported at fair value, with unrealized gains and losses, net of tax, included as a separate component of comprehensive income. The value of these securities, as of December 31, 2006 and 2005, were $7,233 and $5,723, respectively. Unrealized gains associated with the available-for-sale securities were $202, $113, and $142 for the years ended December 31, 2006, 2005, and 2004 respectively. The bond instruments valued at $3,424 and $592 for the years ended December 31, 2006 and 2005 have maturity dates of September 2007 and February 2008. The unrealized gains from trading securities are recorded in other income.

Decreases in market values of individual securities below cost for a duration of six to nine months are deemed indicative of other than temporary impairment. Other than temporary impairments are recorded by writing down the carrying amount of the investments to market value through other income (expense). For the years ended December 31, 2006, 2005 and 2004, there were no impairment charges.

Concentration of Credit Risk

Financial instruments that potentially subject the Group to concentrations of credit risk consist primarily of cash equivalents, short-term investments and trade receivables. The risk with respect to cash equivalents and short-term investments is minimized by the Group's policy of investing with high-quality financial institutions and monitoring the amount of credit exposure to any one financial institution. The risk with respect to trade receivables is minimized by the creditworthiness and diversity of the Group's customer base. Management performs periodic credit evaluations of its customers' financial condition, and generally requires an advanced deposit for a portion of the purchase price. The Group maintains allowances for potential credit losses, which have been within management's expectations. For the years ended December 31, 2006, 2005, and 2004, no sales to or receivables from any single customer exceeded 10% of Bruker BioSpin Group's product revenue or accounts receivables.

Inventories

Components of inventory include raw materials, work-in-process, demonstration units and finished goods. Demonstration units include units which are located in the Group's demonstration laboratories and at potential customer sites and are considered available for sale. Finished goods include in-transit systems that have been shipped to the Group's customers, but not yet installed and accepted by the customer. All inventories are stated at the lower of cost or market, cost determined principally by the first-in, first-out ("FIFO") method. The Group reduces the carrying value of its inventories for differences between the cost and estimated net realizable value taking into consideration usage in the preceding twelve months, expected demand, technological obsolescence and other information including the physical condition of demonstration and in-transit inventories.

F-8

The Group records as a charge to the cost of product revenue for the amount required to reduce the carrying value of inventory to net realizable value. Costs associated with the procurement and warehousing of inventories, such as inbound freight charges and purchasing and receiving costs, are included in the cost of product revenue line item within the statement of operations.

Software Costs

Purchased software is capitalized and amortized over the estimated useful life, generally three years. Costs incurred developing software for use in the Group's products are expensed as incurred and classified as research and development expense.

Property, Plant and Equipment

Property, plant and equipment are stated at cost less accumulated depreciation and amortization. Major improvements are capitalized while expenditures for maintenance, repairs, and minor improvements are charged to expense. When assets are retired or otherwise disposed of, the assets and related accumulated depreciation are eliminated from the accounts and any resulting gains or loss is reflected in the statement of operations. Depreciable assets are depreciated on a straight-line basis over the estimated useful lives of the assets as follows:

Machinery and equipment		5-7 years
Furniture and equipment		3-5 years
Leasehold improvements		Lesser of 15 years or the lease term
Buildings		25-39 years

Intangible Assets

Intangible assets with a finite useful life are amortized on a straight-line basis over their estimated useful lives. Refer to Note 4 for further discussion.

Long-Lived Assets

The Group reviews long-lived assets for impairment in accordance with SFAS No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets. Impairment losses are recorded on long-lived assets used in operations when indicators of impairment are present and the quoted market price, if available, or the estimated undiscounted operating cash flows generated by those assets are less than the assets' carrying value. Impairment losses are charged to the statement of operations for the difference between the fair value and carrying value of the asset. No impairment losses were recorded on long-lived assets during the years ended December 31, 2006 and 2005. Due to the poor financial performance and uncertain outlook related to the Group's investment in Cengent, Inc. (formerly Geneformatics), management performed an investment impairment analysis in 2004 and conduded that the investment had suffered an impairment that was deemed to be other than temporary. As such, the Group recorded a $349 charge to other expense to write off the investment as of December 31, 2004.

F-9

Warranty Costs

The Group typically provides a one to two-year parts and labor warranty with the purchase of equipment. The anticipated cost for this warranty is accrued upon recognition of the sale and is included as a liability on the accompanying combined balance sheets.

Changes to the product warranty liability during the period were as follows:

					December 31
		September 30 2007			December 31
		September 30 2007			2006			2005
		(Unaudited)
Balance at beginning of period		$	9,994		$	10,081		$	12,182
	Warranties issued during period		8,345			10,984			14,368
	Setlements made during period		(7,239	)		(11,957	)		(15,225	)
	Foreign currency impact		1,147			886			(1,244	)

Balance at end of period		$	12,247		$	9,994		$	10,081

Customer Deposits

Under the terms and conditions of its contracts, the Group often requires an advance deposit for a portion of the purchase price of its products. These deposits are recorded as a liability until the associated revenue is recognized upon acceptance of the system.

Fair Value of Financial Instruments

The Group's financial instruments consist primarily of cash and cash equivalents, short-term investments, accounts receivable, short-term bank borrowings, accounts payable, long-term debt, amounts due to and from Bruker-affiliated entities and notes receivable from Bruker-affiliated entities and derivative instruments. The carrying value of the Group's cash and cash equivalents, short-term investments, accounts receivable, short-term bank borrowings, accounts payable and amounts due to and from Bruker-affiliated entities approximate fair value due to their short-term nature. The carrying values of the notes receivable from Bruker-affiliated entities and long-term debt approximate fair value, estimated using interest rates available to the Group for similar items.

Foreign Currency Translation and Transactions

In accordance with SFAS No. 52, Foreign Currency Translation, all balance sheet items of foreign subsidiaries are translated into United States dollars at the current exchange rate at the balance sheet date. Results of operations of foreign subsidiaries are translated at the average exchange rate prevailing throughout the year. Resulting translation adjustments are made directly to shareholders' equity and are included in accumulated other comprehensive income.

Gains and losses resulting from the settlement of transactions denominated in currencies other then the functional currency of the operating entity are recorded in other income (expenses).

F-10

Shipping and Handling Costs

The Group records costs incurred in connection with shipping and handling products as marketing and selling expenses. Amounts billed to customers in connection with these costs are included in product revenue. Shipping and handling costs approximated $4,968, $5,132 and $5,388 in the years ended December 31, 2006, 2005 and 2004, respectively.

Advertising Costs

Advertising costs are expensed as incurred. Advertising expenses included in marketing and selling expenses approximated $2,477, $1,889 and $2,115 for the years ended December 31, 2006, 2005 and 2004, respectively.

Revenue Recognition

The Group recognizes revenue from system sales when persuasive evidence of an arrangement exists, the price is fixed or determinable, title and risk of loss has been transferred to the customer and collectibility of the resulting receivable is reasonably assured. Title and risk of loss is generally transferred to the customer upon receipt of a signed customer acceptance for a system that has been shipped, installed, and for which the customer has been trained. As a result, the timing of customer acceptance or readiness could cause the Group's reported revenues to differ materially from expectations. When products are sold through an independent distributor, a strategic distribution partner or an unconsolidated affiliated distributor, which assumes responsibility for installation, the Group recognizes the system as revenue when the product has been shipped and title and risk of loss has been transferred. The Group's distributors do not have price protection rights or rights to return; however, our products are warranted to be free from defects for a period of one to two years. Revenue is deferred until cash is received when a significant portion of the fee is due over one year after delivery, installation and acceptance of the system. For arrangements with multiple elements, the Group recognizes revenue for each element based on the fair value of the element provided when all other criteria for revenue recognition have been met. The fair value for each element provided in multiple element arrangements is typically determined by referencing historical pricing policies when the element is sold separately. Changes in the Group's ability to establish the fair value for each element in multiple element arrangements could affect the timing of revenue recognition.

Revenue from the sale of accessories and parts is recognized upon shipment and service revenue is recognized as the services are performed.

Research and Development

Research and development costs are expensed as incurred.

Income Taxes

The Group accounts for income taxes in accordance with SFAS No. 109, Accounting for Income Taxes. Under this method, tax provisions and credits are recorded at statutory rates for taxable items

F-11

included in the combined statement of operations regardless of the period in which such items are reported for income tax purposes. Deferred income taxes are recognized for temporary differences between financial statement and income tax bases of assets and liabilities for which income tax benefits will be realized in future years. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts expected to be realized. There are no tax-sharing agreements among any of the companies comprising the Group. The tax provision, as well as the deferred tax assets and liabilities in the combined financial statements, represents the aggregate of the income tax expense, deferred tax assets and deferred tax liabilities of the individual companies within the Group.

Contingencies

The Group is subject to proceedings, lawsuits and other claims related to patents, products and other matters. Management assesses the likelihood of any adverse judgments or outcomes of these matters, as well as potential ranges of probable losses. A determination of the amount of reserves required, if any, for these contingencies are made after careful analysis of each individual issue. The required reserves may change in the future due to new developments in each matter or changes in approach, such as a change in settlement strategy in dealing with these matters.

Derivative Instruments

The Group manufactures and sells its products in a number of countries throughout the world and, as a result, is exposed to movements in foreign currency exchange rates. The Group periodically enters into forward currency exchange contracts and options to hedge its exposure for product sales recorded in EURO (€) currency to be redeemed in U.S. Dollars. The Group accounts for derivative financial instruments in accordance with SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities, as amended, which requires that all derivative instruments be reported on the balance sheet at fair value and establishes criteria for designation and effectiveness of hedging relationships. Changes in the fair value of derivatives are recorded each period in current operations or in stockholders' equity as other comprehensive income depending upon whether the derivative is designated as part of a hedge transaction and, if it is, the type of hedge transaction.

The Group periodically enters into purchase and sales contracts denominated in currencies other than the functional currency of the parties to the transaction. In accordance with SFAS 133, the Group accounts for these transactions separately valuing the "embedded derivative" component of these contracts. The derivative component is marked to market in the combined balance sheet with subsequent changes in the fair value recorded in earnings.

Recent Accounting Developments

In February 2007, the Financial Accounting Standards Board ("FASB") issued Statement of Financial Accounting Standard ("SFAS") No. 159, The Fair Value Option for Financial Assets and Liabilities, Including an amendment of FASB Statement No. 115, ("SFAS 159"). This Statement permits entities to choose to measure many financial instruments and certain other items at fair value that are not currently required to be measured at fair value. SFAS 159 is effective as of the beginning of fiscal 2008. The Company is currently assessing the effect, if any, that the adoption of SFAS 159 will have on its results of operations and financial position.

F-12

In September 2006, the FASB issued SFAS No. 158, Employers Accounting for Defined Benefit Pension and Other Postretirement Plans—an amendment of FASB Statements No. 87, 88, 106 and 132(R). This Statement requires an employer to recognize the over-funded or under-funded status of defined benefit pension and other postretirement defined benefits plans, previously disclosed in the footnotes to the financial statements, as an asset or liability in its statement of financial position and to recognize changes in that funded status in the year in which the changes occur through comprehensive income. This Statement also requires an employer to measure the funded status of a plan as of the date of its year end statement of financial position. In addition, this Statement will require disclosure of the effects of the unrecognized gains or losses, prior service costs and transition asset or obligation on the next fiscal year's net periodic benefit cost. This Statement is effective for fiscal years ending after June 15, 2007. We have adopted SFAS No. 158 as of December 31, 2006 because the information was readily available and it improves the transparency and understandability of our financial statements regarding the costs and obligations of our pension plans. See Note 17 for further discussion of the effect of adopting SFAS No. 158 on the Group's combined financial statements.

In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements ("SFAS 157"). This Statement is effective for fiscal years beginning after November 15, 2007. SFAS 157 provides a common fair value hierarchy for companies to follow in determining fair value measurements in the preparation of financial statements and expands disclosure requirements relating to how such fair value measurements were developed. SFAS 157 clarifies the principle that fair value should be based on the assumptions that the marketplace would use when pricing an asset or liability, rather than company-specific data. The Company is currently assessing the impact that the adoption of SFAS 157 will have on its results of operations and financial position.

In July 2006, the FASB issued Interpretation No. 48, Accounting for Uncertainty in Income Taxes. This Interpretation sets forth a recognition threshold and valuation method to recognize and measure an income tax position taken, or expected to be taken, in a tax return. The evaluation is based on a two-step approach. The first step requires an entity to evaluate whether the tax position would "more likely than not," based upon its technical merits, be sustained upon examination by the appropriate taxing authority. The second step requires the tax position to be measured at the largest amount of tax benefit that is greater than 50 percent likely of being realized upon ultimate settlement. In addition, previously recognized benefits from tax positions that no longer meet the new criteria would no longer be recognized. The application of this Interpretation will be considered a change in accounting principle with the cumulative effect of the change recorded to the opening balance of retained earnings in the period of adoption. This Interpretation will be effective for the Company on January 1, 2008. However, the Company adopted FIN 48 on January 1, 2007, and recorded a reduction of retained earnings of $1,211 effective January 1, 2007.

3. Acquisitions

The acquisitions were accounted for as a purchase in accordance with SFAS No. 141, Business Combinations. Under SFAS No. 141, the total consideration for the business acquisitions was first allocated to the assets acquired and liabilities assumed based on their respective fair values.

The Group acquired the superconducting wire business unit of Morgan Crucible on July 1, 2003. The transaction was to facilitate more efficient production and decrease inventory costs as the acquired business unit manufactures a primary component of the Group's magnetic resonance systems. The

F-13

terms of the acquisition called for earn-out payments based on future net revenues through 2011 to a maximum payment of €48.0 million (approximately $63.3 million at December 31, 2006). Earn-out payments of approximately $5, $5 and $114 were made for sales during the periods ended December 31, 2006, 2005, and 2004, respectively. During 2004, the Group reached an agreement with the former owners, which resulted in a refund of $594. This refund resulted in a purchase price adjustment and a corresponding reduction to goodwill.

In March 2004, the Group acquired certain assets of ZFW, Gottingen, for an initial cash payment of approximately €350 (approximately $437 at March 1, 2004) and earn-out payments of up to €1,200 (approximately $1.58 million at December 31, 2006) for sales between 2007 and 2014. The entire purchase price of $437 represented the fair value of the patents and fixed assets acquired. The business acquired provides research and development for high temperature superconductors.

The Group entered into a Technology Transfer and Asset Purchase Agreement in December 2006 with ShapeMetal Innovation B.V., a former supplier, for a purchase price of €1,500 due in three equal installments of €500. The Group had a pre-existing relationship with ShapeMetal. The initial cash payment of €500 (approximately $660 at December 1, 2006) and milestone payments of €1,000 (approximately $1.32 million at December 31, 2006) represented the fair value of the know how and equipment acquired. The allocation of the purchase price has been made based upon management estimates. The equipment with an approximate fair value of €175 and know how with an approximate fair value of €1,325 were acquired for the manufacturing of powder and powder in tube conductors.

Substantially all of the Group's employees in Switzerland and Japan, as well as certain employees in Germany, are covered by Group-sponsored defined benefit pension plans. Retirement benefits earned are generally based on years of service and compensation during active employment. Eligibility is generally determined in accordance with local statutory requirements. However, the level of benefits and terms of vesting may vary among plans.

As noted previously in Note 2, the Group adopted SFAS No. 158 on December 31, 2006. The adjustment to other comprehensive loss upon the adoption of SFAS No. 158 represents the net unrecognized actuarial losses and unrecognized prior service costs as of the date of adoption. These amounts were previously netted against the plan's funded status in our combined balance sheet. We will recognize these amounts in future periods as components of net periodic pension cost. The estimated net gain for the defined benefit pension plans that will be amortized from other comprehensive income into net periodic benefit cost over the next fiscal year is approximately $226.

F-25

The following table illustrates the incremental effect of applying SFAS 158 on individual line items on our balance sheet as of December 31, 2006.

The following amounts were recognized in the accompanying combined balance sheet for the Company's defined benefit plans at December 31, 2006 and 2005:

	2006			2005
Non-current assets	$	—		$	7,173
Current liabilities		(360	)
Non-current liabilities		(9,877	)		(7,603	)

Net benefit (obligation) asset	$	(10,237	)	$	271

The following amounts were recognized in accumulated other comprehensive income (loss) in the accompanying combined balance sheet at December 31, 2006 and 2005:

	2006			2005
Minimum pension liability, net of tax provision	$	(61	)	$	(414	)
Net actuarial loss, net of tax provision of $1,950		(7,574	)		—

	$	(7,635	)	$	(414	)

Weighted average assumptions used in the calculation of the pension obligation and determining the net periodic pension cost were:

	2006				2005
	Germany		Others		Germany		Others
Annual discount rate	4.00-4.25	%	2.20-2.80	%	4.00-4.25	%	2.50-2.70	%
Expected return on plan assets	—		3.78	%	—		3.78	%
Expected rate of salary increases	2.50	%	1.50-2.50	%	2.50	%	1.50-2.50	%

To determine the expected long-term rate of return on pension plan assets, we consider the current and expected asset allocations, as well as historical and expected returns on various categories of plan assets. For the principal pension plans, we apply our expected rate of return to a market-related value of assets, which stabilizes variability in assets to which we apply that expected return.

Net Periodic Pension Cost

The components of the Group's net periodic cost are as follows:

		2006			2005			2004
Components of net periodic pension cost
	Service cost	$	2,334		$	4,093		$	3,960
	Interest cost		2,118			2,478			2,277
	Expected return on plan assets		(2,541	)		(2,378	)		(2,331	)
	Amortization of prior service cost and actuarial gains and losses		614			442			233

Net periodic pension cost		$	2,525		$	4,635		$	4,139

F-27

At December 31, 2006 and 2005, one of the Group's defined benefit pension plans has an accumulated benefit obligation of $67,319 and $61,037 and plan asset fair values totaling $72,408 and $62,949, respectively. The remainder of the Group's plans are unfunded plans with an aggregate accumulated benefit obligation of $8,534 and $7,692 as of December 31, 2006 and 2005, respectively.

As required under SFAS No. 158, the Group's total defined benefit pension liability includes $1,400 related to a plan in Switzerland (Swiss Plan) at December 31, 2006. The funding policy of the Swiss Plan is consistent with the local government and tax requirements. The Swiss Plan is not required to be funded pursuant to Swiss government and tax requirements.

Asset Allocations by Asset Category

The Group's weighted-average pension plan asset allocation at December 31, 2006 and 2005, by asset category, is as follows:

	2006		2005
Debt securities	43	%	48	%
Equity securities	31		34
Cash	12		2
Property	8		9
Mortgages	6		7

Total	100	%	100	%

Plan fiduciaries set investment policies and strategies for the trust. Long-term strategic investment objectives include preserving the funded status of the trust and balancing risk and return. The plan fiduciaries oversee the investment allocation process, which includes selecting investment managers, setting long-term strategic targets and monitoring asset allocations. Target allocation ranges are guidelines, not limitations, and occasionally plan fiduciaries will approve allocations above or below a target range.

The long-term investment strategy is to achieve a rate of return on assets of 4.5% a year. The investment strategy is limited to investing in a maximum of 35% in equity securities and a maximum of 30% in foreign currencies.

The Group expects to contribute approximately $1,976 to its pension plans during 2007.

F-28

Estimated Future Benefit Payments

The following benefit payments, which reflect future employee service as appropriate, are expected to be paid. The benefit payments are based on the same assumptions used to measure the Group's benefit obligation at December 31, 2006.

2007	$	2,931
2008		964
2009		1,336
2010		1,460
2011		1,762
2012 and beyond		13,998

Other Plans

Employees in certain other countries are covered by defined contribution plans. Generally, contributions are based on a percentage of employees' salary. Employer contributions charged to operations were approximately $750, $864 and $779 in the years ended December 31, 2006, 2005 and 2004, respectively.

18. Accumulated Other Comprehensive Income and Comprehensive Income

Certain companies within the Group have been parties to litigation alleging patent infringement against patents of their competitors. During 2004, the Group recorded a charge of $28,469 to cover costs associated with loss and related legal fees to the extent such amounts were deemed both probable and estimable.

A-1-35

prior to the Cut-Off Date; provided, however, that the following representations and warranties shall survive and remain in full force and effect for the period indicated:

The covenants and agreements of Sellers and BioSpin U.S. contained in this U.S. SPA shall survive and remain in full force and effect for the applicable period specified therein, or if no such period is specified, indefinitely. The provisions of this Article IX shall survive for so long as any other Section of this U.S. SPA shall survive.

Section 9.2 Indemnification Obligations. Sellers agree to jointly and severally indemnify, defend and hold harmless BRKR and any parent, Subsidiary, associate, Affiliate, director, manager, officer, stockholder, employee or agent thereof, and their respective representatives, successors and permitted assigns (all of the foregoing are collectively referred to as the "BRKR Indemnified Parties") from and against, and pay on behalf of or reimburse such party in respect of, as and when incurred, all Losses which any such party may actually incur, suffer, sustain or become subject to or accrue, as a result of, in connection with, or relating to or by virtue of:

(a) any inaccuracy in, or breach of, any representation or warranty made by BioSpin U.S. or Sellers under this U.S. SPA or any Ancillary Agreement, other than any representation or warranty in Section 4.21 (Taxes and Tax Returns), it being understood that such representations and warranties shall be interpreted without giving effect to any limitations or qualifications as to "materiality" (including the word "material" or "Material Adverse Effect") set forth therein;

A-1-36

Section 9.3 Indemnification Procedure.

(a) If any BRKR Indemnified Party intends to seek indemnification pursuant to this Article IX, such BRKR Indemnified Party shall promptly notify Sellers in writing. The BRKR Indemnified Party will provide Sellers with prompt notice of any third-party claim in respect of which indemnification is sought. The failure to provide either such notice will not affect any rights hereunder except to the extent Sellers are materially prejudiced thereby.

(b) If such claim involves a claim by a Third Party against the BRKR Indemnified Parties, Sellers may, upon notice to the BRKR Indemnified Parties, assume, through counsel of Sellers' choosing and at Sellers' expense, the settlement or defense thereof, and the BRKR Indemnified Parties shall reasonably cooperate with Sellers in connection therewith; provided, that the BRKR Indemnified Parties may participate in such settlement or defense through counsel chosen by them; provided, further, that if the BRKR Indemnified Parties reasonably determine that representation by the counsel of Sellers and the BRKR Indemnified Parties may present such counsel with a conflict of interest, then Sellers shall pay the reasonable fees and expenses of the BRKR Indemnified Parties' counsel. Notwithstanding anything in this Section 9.3 to the contrary, Sellers may not, without the prior written consent of the BRKR Indemnified Parties, settle or compromise any action or consent to the entry of any judgment, such consent not to be unreasonably withheld. So long as Sellers are contesting any such claim in good faith, the BRKR Indemnified Parties shall not pay or settle any such claim without Sellers' consent, such consent not to be unreasonably withheld. If Sellers are not contesting such claim in good faith, then the BRKR Indemnified Parties may conduct and control, through counsel of their own choosing and at Sellers' expense, the settlement or defense thereof, and Sellers shall cooperate with it in connection therewith. The failure of the BRKR Indemnified Parties to participate in, conduct or control such defense shall not relieve Sellers of any obligation they may have hereunder.

(c) Notwithstanding anything to the contrary in this Section 9.3, to the extent a claim for which indemnification is sought by BRKR Indemnified Parties relates to Taxes for a taxable period beginning on or before and ending after the Closing Date, Sellers and BRKR shall jointly control any proceeding in respect of such claim and neither party shall settle or compromise any action or consent to the entry of any judgment with respect thereto without the prior written consent of the other party, such consent not to be unreasonably withheld.

Section 9.4 Calculation of Indemnity Payments. The amount of any Loss for which indemnification is provided under this Article IX shall be (a) increased to the extent necessary such that after payment of any net Tax cost by the BRKR Indemnified Parties with respect to the receipt or accrual of indemnity payments hereunder, as increased pursuant to this clause (a), the amount remaining shall be the amount of the indemnity payment prior to any increase pursuant to this clause (a) and (b) reduced by the amount of the net Tax benefit actually realized by the BRKR Indemnified Parties by reason of such Loss (as an illustrative example, clause (b) takes into account on a present value basis any net Tax benefit actually realized by the BRKR Indemnified Party by reason of the indemnified Loss in a Tax jurisdiction or Tax year other than the jurisdiction or year in which such Loss arose).

Section 9.5 Indemnification Amounts.

(a) Notwithstanding any provision to the contrary contained in this U.S. SPA, Sellers shall not be obligated to indemnify the BRKR Indemnified Parties for any Losses pursuant to this Article IX to the extent they are a result of any claim made pursuant to Section 9.2(a) unless and until the dollar amount of all Losses in the aggregate from claims made pursuant to Section 9.2(a), Section 10.2(a) of the Swiss Merger Agreement and Section 9.2(a) of the German SPA exceed $3,250,000, in which case Sellers will be obligated to indemnify the BRKR Indemnified Parties for the total amount of Losses including any amounts which would otherwise not be required to be

A-1-37

paid by reason of this Section 9.5; provided, however, that in no event shall the aggregate indemnification obligations of Sellers pursuant to Sections 9.2(a), (b) or (c) of this U.S. SPA, Sections 10.2(a), (b) or (c) of the Swiss Merger Agreement, and Sections 9.2(a), (b) or (c) of the German SPA exceed Ninety Two Million Dollars ($92,000,000) (the "Indemnity Cap"); provided, further, that notwithstanding the foregoing, the BRKR Indemnified Parties' right to seek indemnification hereunder for any Losses arising out of (i) criminal activity or fraud (in each case as determined in a final, non-appealable decision by a court of competent jurisdiction) of Sellers or BioSpin U.S. or (ii) Section 3.8 (Ownership of the Shares), Section 3.9 (Withholding Tax), Section 4.3 (Capitalization of BioSpin U.S.), Section 4.4(Capitalization of the Subsidiaries; Other Interests) or Section 4.17 (Environmental) shall not be subject to, or limited by, the limits contained in this Section 9.5; provided, further, that with respect to any Losses arising out of Section 3.8 (Ownership of Shares) and Section 3.9 (Withholding Tax), the liability of any Seller beyond the Indemnity Cap shall be several and not joint. Notwithstanding the foregoing, no Seller shall have any liability under this Article IX or otherwise under this U.S. SPA in excess of the amount set forth opposite such Seller's name under the heading "Individual Selling Shareholders' Indemnity Cap" as set forth on Schedule 9.5.

(b) For the purpose of calculating the amount of any Loss for which a BRKR Indemnified Party is entitled to indemnification under this U.S. SPA, the amount of each Loss shall be deemed to be an amount net of any insurance proceeds and any indemnity, contribution or other similar payment that has been paid by any insurer or other third party with respect thereto. The reasonable out-of-pocket costs and expenses (including reasonable fees and disbursements of counsel) actually incurred by the BRKR Indemnified Parties in pursuing any insurance proceeds or indemnity, contribution or other similar payment from any insurer or other third party under this Article IX shall constitute additional Losses with respect to the matter for which indemnification may be sought hereunder, except to the extent such costs and expenses are paid or reimbursed by such insurer or other third party. In the event that a BRKR Indemnified Party is paid by Sellers for a Loss for which one or more insurance claims or claims against Third Parties has been or could be made, but for which payment from such insurer or Third Party has not been received, then such Purchaser Indemnified Party shall assign, to the extent legally permissible, all such claims to Sellers for purposes of recouping payment of such Loss. To the extent such assignment should not be legally permissible, the respective BRKR Indemnified Party shall remit any payment received, up to the amount of such Loss, from such insurance claim or Third Party claim to Sellers.

Section 9.6 Exclusive Remedy. BRKR acknowledges and agrees that the indemnification provisions of this Article IX shall be the sole and exclusive remedies of BRKR against Sellers and BioSpin U.S. for any breach by Sellers or BioSpin U.S. of the representations and warranties in this U.S. SPA, for any failure by Sellers or BioSpin U.S. to perform and comply with any covenants and agreements in this U.S. SPA that are required to be complied with or performed prior to the Closing and for any failure by Sellers or BioSpin U.S. to perform and comply with any covenants and agreements in this U.S. SPA, except that if any of the provisions of this U.S. SPA are not performed in accordance with their terms or are otherwise breached, BRKR shall be entitled to specific performance of the terms thereof in addition to any other remedy at law or equity. Notwithstanding anything contained in this U.S. SPA to the contrary, BRKR shall retain the right to receive damages or other relief (including equitable relief) against BioSpin U.S. or Sellers as a result of any criminal activity or fraudulent action (in each case as determined in a final, non-appealable decision by a court of competent jurisdiction) by BioSpin U.S. or Sellers without regard to any restriction or limitation contained herein. The indemnification obligations contained in this Article IX are obligations of Sellers and not of BioSpin U.S.

Except as provided in the immediately preceding sentence, no action taken pursuant to this U.S. SPA will be deemed to constitute a waiver of compliance with any representations, warranties, conditions or covenants contained in this U.S. SPA and will not operate or be construed as a waiver of any subsequent breach, whether of a similar or dissimilar nature.

Section 10.5 Entire Agreement; Schedules. This U.S. SPA, the Swiss Merger Agreement and the German SPA, which includes the schedules and exhibits hereto and thereto, supersedes any other agreement, whether written or oral, that may have been made or entered into by any party relating to the matters contemplated by this U.S. SPA and such other agreements and constitutes the entire agreement by and among the Parties relating to these matters.

Section 10.6 Amendments, Supplements, Etc. This U.S. SPA may be amended or supplemented at any time by additional written agreements as may mutually be determined by BioSpin U.S., BRKR and Sellers to be necessary, desirable or expedient to further the purposes of this U.S. SPA or to clarify the intention of the Parties.

Each of the Parties irrevocably agrees that any legal action or proceeding with respect to this U.S. SPA or for recognition and enforcement of any judgment in respect hereof shall be brought and determined in the United States District Court for the Eastern District of Massachusetts or if such legal action or proceeding may not be brought in such court for jurisdictional purposes, in the Superior Court of Massachusetts. Each of the Parties hereby (a) irrevocably submits with regard to any such action or proceeding to the exclusive personal jurisdiction of the aforesaid courts in the event any dispute arises out of this U.S. SPA or any transaction contemplated hereby and waives the defense of sovereign

A-1-40

Section 10.8 Waiver of Jury Trial. Each of the Parties hereby waives to the fullest extent permitted by applicable law any right it may have to a trial by jury with respect to any litigation directly or indirectly arising out of, under or in connection with this U.S. SPA or the transactions contemplated by this U.S. SPA. Each of the Parties hereby (a) certifies that no representative, agent or attorney of the other Party has represented, expressly or otherwise, that such other Party would not, in the event of litigation, seek to enforce the foregoing waiver and (b) acknowledges that it has been induced to enter into this U.S. SPA and the transactions contemplated by this U.S. SPA, as applicable, by, among other things, the mutual waivers and certifications in this Section 10.8.

Section 10.9 Actions by Sellers. Where any provision of this U.S. SPA indicates that BioSpin U.S. will take any specified action (or refrain from taking any specified action) or requires BioSpin U.S. to take any specified action (or to refrain from taking any specified action), then, regardless of whether this U.S. SPA specifically provides that Sellers will do so, Sellers shall cause BioSpin U.S. to take such action (or to refrain from taking such action, as applicable). Sellers will be responsible for the failure of BioSpin U.S. to take any such action (or to refrain from taking any such action, as applicable).

Section 10.10 Execution in Counterparts. This U.S. SPA may be executed in two or more counterparts, each of which will be deemed an original, but all of which together will constitute one and the same agreement.

Section 10.12 Invalid Provisions. If any provision of this U.S. SPA is held to be illegal, invalid or unenforceable under any present or future Law, and if the rights or obligations under this U.S. SPA of Sellers on the one hand and BRKR on the other hand will not be materially and adversely affected thereby, (a) such provision will be fully severable, (b) this U.S. SPA will be construed and enforced as if such illegal, invalid, or unenforceable provision had never comprised a part hereof, (c) the remaining provisions of this U.S. SPA will remain in full force and effect and will not be affected by the illegal, invalid, or unenforceable provision or by its severance from this U.S. SPA and (d) in lieu of such illegal, invalid or unenforceable provision, there will be added automatically as a part of this U.S. SPA a legal, valid and enforceable provision as similar in terms to such illegal, invalid or unenforceable provision as may be possible.

Section 10.13 Publicity. The Parties agree that except as otherwise required by applicable Law or the rules and regulations of any national securities exchange, no Party shall issue any press release or otherwise make any public statement with respect to the transactions contemplated by this U.S. SPA or the Ancillary Agreements without prior consultation with and consent of BRKR and Sellers, which consent shall not be unreasonably withheld, conditioned or delayed. A mutually agreed press release is attached hereto as Exhibit D.

Section 10.14 Specific Performance. The Parties agree that if any of the provisions of this U.S. SPA were not performed in accordance with their specific terms or were otherwise breached, irreparable damage would occur, no adequate remedy at law would exist and damages would be difficult to determine, and that the Parties shall be entitled to specific performance of the terms hereof, in addition to any other remedy at law or equity.

Section 8.1 Termination. This German SPA may be terminated and the transactions contemplated by this German SPA may be abandoned at any time prior to the Closing:

(a) by mutual written consent of Purchasers and Sellers;

(b) by Sellers or Purchasers, if:

(i) a Governmental Authority shall have issued an order, decree or ruling or taken any other action (which order, decree or ruling the Parties shall use reasonable best efforts to lift), in each case permanently restraining, enjoining or otherwise prohibiting the transactions contemplated by this German SPA and such order, decree, ruling or other action shall have become final and nonappealable;

(ii) the Closing shall not have occurred on or before June 30, 2008 (other than due principally to the failure of the Party seeking to terminate this German SPA to perform any obligations under this German SPA required to be performed by it at or prior to the Closing);

(iii) the shareholder approvals of BRKR shall not have been obtained at the respective shareholders meetings or at any adjournment or postponement thereof; or

(iv) the Swiss Merger Agreement or the U.S. SPA shall have been terminated.

(d) by Sellers, if there is a default or breach by Purchasers with respect to the due and timely performance of any of its covenants or agreements contained herein, or if the representations or warranties of Purchasers contained in this German SPA shall have become inaccurate, in either case such that the conditions set forth in Section 7.3 would not be satisfied and such breach or default or inaccuracy is not curable or, if curable, has not been cured or waived within twenty (20) calendar days after written notice to Purchasers specifying, in reasonable detail, such claimed default, breach or inaccuracy and demanding its cure or satisfaction.

Section 8.2 Procedure and Effect of Termination. In the event of termination and abandonment of the transactions contemplated by this German SPA pursuant to Section 8.1, written notice thereof shall forthwith be given to the other Parties and this German SPA shall terminate (subject to the provisions of this Section 8.2) and the transactions contemplated by this German SPA shall be abandoned, without further action by any of the Parties.

A-2-35

Nothing contained in this Section 8.2 shall relieve any party from liability for any breach of this German SPA.

ARTICLE IX
SURVIVAL; INDEMNIFICATION

Section 9.1 Survival of Indemnification Rights. Subject to the limitations and other provisions of this German SPA, the representations and warranties of Sellers in Article III and of the Target Companies and Sellers in Article IV shall survive the Closing and remain in full force and effect until the later of the Cut-Off Date and the resolution of any claim for indemnification with respect to which any Purchaser Indemnified Party has provided Sellers notice of a claim for indemnification pursuant to Section 9.3(a) prior to the Cut-Off Date; provided, however, the following representations and warranties shall survive and remain in full force and effect for the period indicated:

(a) Section 3.8 (Ownership of the Shares), Section 4.3 (Capitalization of the Target Companies) and Section 4.4 (Capitalization of the Subsidiaries; Other Interests), ten (10) years following the Closing Date;

(b) Section 4.16 (Environmental), Section 4.18 (Labor Relations and Employee Benefits), Section 4.20 (Proprietary Rights) and Section 4.27 (No Misleading Statements), three (3) years following the Closing Date; and

(c) Section 3.9 (Withholding Tax) and Section 4.19 (Taxes and Tax Returns), until sixty (60) calendar days after expiration of the applicable statute of limitations (including any extension thereof);

and with respect to clauses (a), (b) and (c), if a claims notice has been provided by such date, shall remain in full force and effect until final resolution thereof.

The covenants and agreements of Sellers and the Target Companies contained in this German SPA shall survive and remain in full force and effect for the applicable period specified therein, or if no such period is specified, indefinitely. The provisions of this Article IX shall survive for so long as any other Section of this German SPA shall survive.

Section 9.2 Indemnification Obligations. Sellers agree to jointly and severally indemnify, defend and hold harmless Purchasers, and, after the acquisition of the BPhysik Shares, Bruker Physik, and any parent, Subsidiary, associate, Affiliate, director, manager, officer, stockholder, employee or agent thereof, and their respective representatives, successors and permitted assigns (all of the foregoing are collectively referred to as the "Purchaser Indemnified Parties") from and against, and pay on behalf of or reimburse such party in respect of, as and when incurred, all Losses which any such party may actually incur, suffer, sustain or become subject to or accrue, as a result of, in connection with, or relating to or by virtue of:

(a) any inaccuracy in, or breach of, any representation or warranty made by a Target Company or Sellers under this German SPA or any Ancillary Agreement, other than any representation or warranty in Section 4.19 (Taxes and Tax Returns), it being understood that such representations and warranties shall be interpreted without giving effect to any limitations or qualifications as to "materiality" (including the word "material" or "Material Adverse Effect") set forth therein;

A-2-36

(b) any breach or nonfulfillment of any covenant or agreement on the part of Sellers or a Target Company in respect of pre-Closing covenants, under this German SPA or any Ancillary Agreement;

(c) any fees, expenses or other payments incurred or owed by Sellers or a Target Company to any agent, broker, investment banker or other firm or Person retained or employed by Sellers or a Target Company in connection with the transactions contemplated by this German SPA; or

(d) any inaccuracy in, or breach of, any representation or warranty in Section 4.19 of this German SPA, Section 4.21 of the Swiss Merger Agreement or Section 4.21 of the U.S. SPA to the extent that the aggregate amount of all such Losses exceeds $10,000,000 (the "Tax Deductible") (other than Losses arising from criminal activity or fraud—in each case as determined in a final, non-appealable decision by a court of competent jurisdiction—of Sellers or the Target Companies, which Losses shall not be subject to the Tax Deductible), it being understood that such representations and warranties shall be interpreted without giving effect to any exceptions or disclosures made with respect thereto on the disclosure schedules to this German SPA, the Swiss Merger Agreement or the U.S. SPA; provided, however, that any Taxes of a Subsidiary attributable to the payment of a Subsidiary Dividend (as defined in the Swiss Merger Agreement) shall not be applied against the Tax Deductible.

Section 9.3 Indemnification Procedure.

(a) If any Purchaser Indemnified Party intends to seek indemnification pursuant to this Article IX, such Purchaser Indemnified Party shall promptly notify Sellers in writing. The Purchaser Indemnified Party will provide Sellers with prompt notice of any third-party claim in respect of which indemnification is sought. The failure to provide either such notice will not affect any rights hereunder except to the extent Sellers are materially prejudiced thereby.

(b) If such claim involves a claim by a Third Party against the Purchaser Indemnified Parties, Sellers may, upon notice to the Purchaser Indemnified Parties, assume, through counsel of Sellers' choosing and at Sellers' expense, the settlement or defense thereof, and the Purchaser Indemnified Parties shall reasonably cooperate with Sellers in connection therewith; provided, that the Purchaser Indemnified Parties may participate in such settlement or defense through counsel chosen by them; provided, further, that if the Purchaser Indemnified Parties reasonably determine that representation by the counsel of Sellers and the Purchaser Indemnified Parties may present such counsel with a conflict of interests, then Sellers shall pay the reasonable fees and expenses of the Purchaser Indemnified Parties' counsel. Notwithstanding anything in this Section 9.3 to the contrary, Sellers may not, without the prior written consent of the Purchaser Indemnified Parties, settle or compromise any action or consent to the entry of any judgment, such consent not to be unreasonably withheld. So long as Sellers are contesting any such claim in good faith, the Purchaser Indemnified Parties shall not pay or settle any such claim without Sellers' consent, such consent not to be unreasonably withheld. If Sellers are not contesting such claim in good faith, then the Purchaser Indemnified Parties may conduct and control, through counsel of their own choosing and at Sellers' expense, the settlement or defense thereof, and Sellers shall cooperate with it in connection therewith. The failure of the Purchaser Indemnified Parties to participate in, conduct or control such defense shall not relieve Sellers of any obligation they may have hereunder.

(c) Notwithstanding anything to the contrary in this Section 9.3, to the extent a claim for which indemnification is sought by Purchaser Indemnified Parties relates to Taxes for a taxable period beginning on or before and ending after the Closing Date, Sellers and Purchaser Indemnified Parties shall jointly control any proceeding in respect of such claim and neither party shall settle or compromise any action or consent to the entry of any judgment with respect thereto without the prior written consent of the other party, such consent not to be unreasonably withheld.

A-2-37

Section 9.4 Calculation of Indemnity Payments. The amount of any Loss for which indemnification is provided under this Article IX shall be (a) increased to the extent necessary such that after payment of any net Tax cost by the Purchaser Indemnified Parties with respect to the receipt or accrual of indemnity payments hereunder, as increased pursuant to this clause (a), the amount remaining shall be the amount of the indemnity payment prior to any increase pursuant to this clause (a) and (b) reduced by the amount of the net Tax benefit actually realized by the Purchaser Indemnified Parties by reason of such Loss (as an illustrative example, clause (b) takes into account on a present value basis any net Tax benefit actually realized by the Purchaser Indemnified Party by reason of the indemnified Loss in a Tax jurisdiction or Tax year other than the jurisdiction or year in which such Loss arose).

Section 9.5 Indemnification Amounts.

(a) Notwithstanding any provision to the contrary contained in this German SPA, Sellers shall not be obligated to indemnify the Purchaser Indemnified Parties for any Losses pursuant to this Article IX to the extent they are a result of any claim made pursuant to Section 9.2(a) unless and until the dollar amount of all Losses in the aggregate from claims made pursuant to Section 9.2(a) of this German SPA, Section 10.2(a) of the Swiss Merger Agreement and Section 9.2(a) of the U.S. SPA exceed $3,250,000, in which case Sellers will be obligated to indemnify the Purchaser Indemnified Parties for the total amount of Losses including any amounts which would otherwise not be required to be paid by reason of this Section 9.5; provided, however, that in no event shall the aggregate indemnification obligations of Sellers pursuant to Sections 9.2(a), (b) or (c) of this German SPA, Sections 10.2(a), (b) or (c) of the Swiss Merger Agreement and Sections 9.2(a), (b) or (c) of the U.S. SPA exceed Ninety Two Million Dollars ($92,000,000) (the "Indemnity Cap"); provided, further, that notwithstanding the foregoing, the Purchaser Indemnified Parties' right to seek indemnification hereunder for any Losses arising out of (i) criminal activity or fraud (in each case as determined in a final, non-appealable decision by a court of competent jurisdiction) of Sellers or the Target Companies or (ii) Section 3.8 (Ownership of the Shares), Section 3.9 (Withholding Tax), Section 4.3 (Capitalization of Bruker Physik), Section 4.4 (Capitalization of the Subsidiaries; Other Interests), or Section 4.16 (Environmental) shall not be subject to, or limited by, the limits contained in this Section 9.5; provided, further, that with respect to any Losses arising out of Section 3.8 (Ownership of Shares) and Section 3.9 (Withholding Tax), the liability of any Seller beyond the Indemnity Cap shall be several and not joint. Notwithstanding the foregoing, no Seller shall have any liability under this Article IX or otherwise under this German SPA in excess of the amount set forth opposite such Seller's name under the heading "Individual Selling Shareholders' Indemnity Cap" as set forth on Schedule 9.5 to the U.S. SPA.

(b) For the purpose of calculating the amount of any Loss for which a Purchaser Indemnified Party is entitled to indemnification under this German SPA, the amount of each Loss shall be deemed to be an amount net of any insurance proceeds and any indemnity, contribution or other similar payment that has been paid by any insurer or other third party with respect thereto. The reasonable out-of-pocket costs and expenses (including reasonable fees and disbursements of counsel) actually incurred by the Purchaser Indemnified Parties in pursuing any insurance proceeds or indemnity, contribution or other similar payment from any insurer or other third party under this Article IX shall constitute additional Losses with respect to the matter for which indemnification may be sought hereunder, except to the extent such costs and expenses are paid or reimbursed by such insurer or other third party. In the event that a Purchaser Indemnified Party is paid by Sellers for a Loss for which one or more insurance claims or claims against Third Parties has been or could be made, but for which payment from such insurer or Third Party has not been received, then such Purchaser Indemnified Party shall assign, to the extent legally permissible, all such claims to Sellers for purposes of recouping payment of such Loss. To the extent such assignment should not be legally permissible, the respective BRKR Indemnified Party shall remit

A-2-38

any payment received, up to the amount of such Loss, from such insurance claim or Third Party claim to Sellers.

(c) Purchasers shall be entitled to recover Losses from the Indemnity Escrow; provided, however, that the recovery is not limited to the amount in the Indemnity Escrow.

Section 9.6 Exclusive Remedy. Purchasers acknowledge and agree that the indemnification provisions of this Article IX shall be the sole and exclusive remedies of Purchasers against Sellers and the Target Companies for any breach by Sellers or the Target Companies of the representations and warranties in this German SPA, for any failure by Sellers or the Target Companies to perform and comply with any covenants and agreements in this German SPA that are required to be complied with or performed prior to the Closing and for any failure by Sellers or the Target Companies to perform and comply with any covenants and agreements in this German SPA, except that if any of the provisions of this German SPA are not performed in accordance with their terms or are otherwise breached, Purchasers shall be entitled to specific performance of the terms thereof in addition to any other remedy at law or equity. Notwithstanding anything contained in this German SPA to the contrary, Purchasers shall retain the right to receive damages or other relief (including equitable relief) against the Target Companies or Sellers as a result of any criminal activity or fraudulent action (in each case as determined in a final, non-appealable decision by a court of competent jurisdiction) by the Target Companies or Sellers without regard to any restriction or limitation contained herein. The indemnification obligations contained in this Article IX are obligations of Sellers and not of the Target Companies.

Subject to the preceding sentence, this German SPA will apply to, be binding in all respects upon, and inure to the benefit of the successors and permitted assigns of the Parties. Notwithstanding anything to the contrary in this Section 10.3, (i) upon written notice to Sellers, Purchasers shall be permitted to assign this German SPA and the rights and obligations under it to a wholly owned, direct or indirect subsidiary of Purchasers and (ii) BRKR shall be permitted to assign this German SPA and the rights and obligations under it to Bruker BioSpin Corporation after the U.S. Closing such that, as a result of such assignment, Bruker BioSpin Corporation shall become Purchaser 1 for all purposes hereunder; provided, that in the event of any such assignment, each Purchaser shall remain liable in full for the performance of its obligations hereunder. Nothing expressed or referred to in this German SPA will be construed to give any Person other than the Parties any legal or equitable right, remedy or claim under or with respect to this German SPA or any provision of this German SPA. This German SPA and all of its provisions and conditions are for the sole and exclusive benefit of the parties to this German SPA and their successors and assigns.

Section 10.4 Extension; Waiver. Either Party may, by written notice to the other Party (a) extend the time for performance of any of the obligations of the other Party under this German SPA, (b) waive any inaccuracies in the representations or warranties of the other Party contained in this German SPA, (c) waive compliance with any of the conditions or covenants of the other Party contained in this German SPA or (d) waive or modify performance of any of the obligations of the other Party under this German SPA; provided, that no Party may, without the prior written consent of the other Party, make or grant such extension of time, waiver of inaccuracies or compliance or waiver or modification of performance with respect to its representations, warranties, conditions or covenants hereunder. Except as provided in the immediately preceding sentence, no action taken pursuant to this German SPA will be deemed to constitute a waiver of compliance with any representations, warranties, conditions or covenants contained in this German SPA and will not operate or be construed as a waiver of any subsequent breach, whether of a similar or dissimilar nature.

Section 10.5 Entire Agreement; Schedules. This German SPA, the Swiss Merger Agreement and the U.S. SPA, which includes the schedules and Schedules hereto and thereto, supersedes any other agreement, whether written or oral, that may have been made or entered into by any party relating to the matters contemplated by this German SPA and such other agreements and constitutes the entire agreement by and among the Parties relating to these matters.

Section 10.6 Amendments, Supplements, Etc. This German SPA may be amended or supplemented at any time by additional written agreements as may mutually be determined by Bruker Physik, Techneon, Purchasers and Sellers to be necessary, desirable or expedient to further the purposes of this German SPA or to clarify the intention of the Parties.

Section 10.7 Applicable Law. This German SPA shall be governed by and construed under the Laws of the Commonwealth of Massachusetts (without regard to the conflict of law principles thereof). Each of the Parties irrevocably agrees that any legal action or proceeding with respect to this German SPA or for recognition and enforcement of any judgment in respect hereof shall be brought and

A-2-41

determined in the United States District Court for the Eastern District of Massachusetts or if such legal action or proceeding may not be brought in such court for jurisdictional purposes, in the Superior Court of Massachusetts. Each of the Parties hereby (a) irrevocably submits with regard to any such action or proceeding to the exclusive personal jurisdiction of the aforesaid courts in the event any dispute arises out of this German SPA or any transaction contemplated hereby and waives the defense of sovereign immunity, (b) agrees that it shall not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court or that such action is brought in an inconvenient forum and (c) agrees that it shall not bring any action relating to this German SPA or any transaction contemplated hereby in any court other than any Massachusetts state or federal court sitting in Boston, Massachusetts.

Section 10.8 Waiver of Jury Trial. Each of the Parties hereby waives to the fullest extent permitted by applicable law any right it may have to a trial by jury with respect to any litigation directly or indirectly arising out of, under or in connection with this German SPA or the transactions contemplated by this German SPA. Each of the Parties hereby (a) certifies that no representative, agent or attorney of the other Party has represented, expressly or otherwise, that such other Party would not, in the event of litigation, seek to enforce the foregoing waiver and (b) acknowledges that it has been induced to enter into this German SPA and the transactions contemplated by this German SPA, as applicable, by, among other things, the mutual waivers and certifications in this Section 10.8.

Section 10.9 Actions by Sellers. Where any provision of this German SPA indicates that a Target Company will take any specified action (or refrain from taking any specified action) or requires a Target Company to take any specified action (or to refrain from taking any specified action), then, regardless of whether this German SPA specifically provides that Sellers will do so, Sellers shall cause the applicable Target Company to take such action (or to refrain from taking such action, as applicable). Sellers will be responsible for the failure of Target Company to take any such action (or to refrain from taking any such action, as applicable).

Section 10.10 Execution in Counterparts. This German SPA may be executed in two or more counterparts, each of which will be deemed an original, but all of which together will constitute one and the same agreement.

Section 10.12 Invalid Provisions. If any provision of this German SPA is held to be illegal, invalid or unenforceable under any present or future Law, and if the rights or obligations under this German SPA of Sellers on the one hand and Purchasers on the other hand will not be materially and adversely affected thereby, (a) such provision will be fully severable, (b) this German SPA will be construed and enforced as if such illegal, invalid, or unenforceable provision had never comprised a part hereof, (c) the remaining provisions of this German SPA will remain in full force and effect and will not be affected by the illegal, invalid, or unenforceable provision or by its severance from this German SPA and (d) in lieu of such illegal, invalid or unenforceable provision, there will be added automatically as a part of this German SPA a legal, valid and enforceable provision as similar in terms to such illegal, invalid or unenforceable provision as may be possible.

Section 10.13 Publicity. The Parties agree that except as otherwise required by applicable Law or the rules and regulations of any national securities exchange, no Party shall issue any press release or otherwise make any public statement with respect to the transactions contemplated by this German SPA or the Ancillary Agreements without prior consultation with and consent of the Purchasers and Sellers, which consent shall not be unreasonably withheld, conditioned or delayed. A mutually agreed press release is attached hereto as Exhibit B.

A-2-42

Section 10.14 Specific Performance. The Parties agree that if any of the provisions of this German SPA were not performed in accordance with their specific terms or were otherwise breached, irreparable damage would occur, no adequate remedy at law would exist and damages would be difficult to determine, and that the Parties shall be entitled to specific performance of the terms hereof, in addition to any other remedy at law or equity.

Section 10.15 Construction.

(a) Whenever the words "include," "includes," or "including" are used in this German SPA, they shall be deemed to be followed by the words "without limitation."

ARTICLE II

SHARE EXCHANGE AND CANCELLATION; MERGER; CLOSING

Section 2.1 Share Exchange. Each Invest Shareholder hereby undertakes to assign, transfer and convey to BRKR (and BRKR undertakes to accept such assignment, transfer and conveyance from Invest Shareholders) at the Closing, upon the terms and subject to the conditions set forth herein, the number of Invest Shares set forth opposite each Invest Shareholder's name on Schedule 2.1 (the "Exchange Shares"), free and clear of any Liens, and BRKR shall deliver to each such Invest Shareholder the number of shares of BRKR Stock (the aggregate of all such shares delivered by BRKR to Invest Shareholders, the "Share Exchange Price") set forth opposite such Invest Shareholder's name on Schedule 2.1-1. The assignment of the Exchange Shares shall not be effected by this Swiss Merger Agreement but by way of a separate assignment deed under Swiss law, to be entered into on the Closing Date, in substantially the form attached hereto as Schedule 2.1-2 (the "Exchange Shares Transfer Deed").

Section 2.2 Share Cancellation. Invest Shareholders hereby undertake to assign, transfer and convey, at the Closing and simultaneously with the consummation of the Share Exchange, upon the terms and subject to the conditions set forth herein, to Invest, and Invest shall accept such assignment, transfer and conveyance from Invest Shareholders, the number of Invest Shares set forth opposite each Invest Shareholder's name on Schedule 2.2 (the "Cancellation Shares"), free and clear of any Liens, and, at the Effective Time and in the Merger, Invest shall deliver to each such Invest Shareholder the number of shares of BRKR Stock (the aggregate of all such shares delivered by Invest to Invest Shareholders, the "Share Cancellation Price", and together with the Share Exchange Price, the "Acquisition Price") set forth opposite such Invest Shareholder's name on Schedule 2.2-1; provided, however, that, in the event that the aggregate number of shares of BRKR Stock listed on Schedule 2.2-1 have a total Fair Market Value greater than CHF 160,000, then the number of shares of BRKR Stock constituting the Share Cancellation Price shall be reduced, and each Invest Shareholder's share of the Share Cancellation Price shall be accordingly reduced on a pro rata basis, to that number of shares of BRKR Stock that have a total Fair Market Value of CHF 160,000. The assignment of the Cancellation Shares shall not be effected by this Swiss Merger Agreement but by way of a separate assignment deed under Swiss law, to be entered into on the Closing Date, in substantially the form attached hereto as Schedule 2.2-2 (the "Cancellation Shares Transfer Deed"). Invest hereby agrees that, upon the receipt of the Cancellation Shares by Invest, the Cancellation Shares shall not confer any membership rights (including voting rights) or any financial rights (including the right to receive dividends) on any Person, until such time as a transfer of such Cancellation Shares by Invest or annulment of such Cancellation Shares by reduction of Invest's share capital shall have occurred.

A-3-6

Section 2.3 Merger. BRKR shall cause Invest and Merger Sub to (i) receive from a specially qualified auditor a confirmation that there are no known or expected claims of Merger Sub and Invest which could be jeopardized due to the Merger (Article 25(2) of the Merger Act), (ii) consult with the employee representatives of the merging entities pursuant to Article 28 of the Merger Act, (iii) execute the Merger Filing, which complies with Article 13 in connection with Articles 23(1)(b) and 24(1) of the Merger Act, attached hereto as Annex B, and (iv) file the executed Merger Filing together with the merger balance sheet as of the Closing produced in accordance with Article 11 of the Merger Act ("Merger Balance Sheet"), with the Commercial Register. Upon the effectiveness of the Merger (the "Effective Time"), Merger Sub will, by operation of Swiss law, merge with and into Invest (referred to after the Merger as the "Surviving Company"). As a result of the Merger, the shares of Merger Sub will automatically be canceled and will cease to exist, all assets, liabilities and obligations of Merger Sub prior to the Merger will automatically be assumed by the Surviving Company and the separate legal existence of Merger Sub shall terminate. Because the Merger qualifies as a simplified merger pursuant to Article 23(1)(b) of the Merger Act, there is no requirement for an increase of the share capital of the Surviving Company and/or an exchange of shares of Merger Sub against shares of Invest. As a result of the Swiss Transactions, Invest Shareholders shall acquire 57,544,872 shares of BRKR Stock and Invest shall become a direct, wholly owned Subsidiary of BRKR.

Section 2.4 The Closing. The closing of the transactions contemplated by this Swiss Merger Agreement (the "Closing" or "Swiss Closing") shall take place at the offices of Dewey & LeBoeuf LLP, 1301 Avenue of the Americas, New York, New York, 10019, at 10:00 a.m., New York time, on the later of (i) January 23, 2008 and (ii) the first (1st) Business Day following the satisfaction or waiver of all conditions to the obligations of the Parties to consummate the Swiss transactions contemplated hereby (other than conditions which by their nature are to be satisfied at the Closing, but subject to the satisfaction or waiver of those conditions) or such other date as BRKR and Invest Shareholders may mutually agree in writing (the "Closing Date"). The Closing shall be deemed to have been consummated at 12:02 a.m., New York time, on the Closing Date.

Section 2.5 Deliveries at Closing. At the Closing:

(a) Invest Shareholders shall deliver the following documents and deliverables:

(i) to BRKR, a share register of Invest duly issued by the board of directors of Invest showing that Invest Shareholders are the only holders of Invest Shares;

(ii) to BRKR, the Exchange Shares Transfer Deed, duly signed by each of Invest Shareholders;

(iii) to Invest, the Cancellation Shares Transfer Deed, duly signed by each of the Invest Shareholders;

(iv) to BRKR and Invest, a circular resolution signed by all members of the board of directors of Invest evidencing that the board of directors of Invest resolved that BRKR and Invest, contingent upon the Closing, shall be registered in Invest's share register as shareholders in respect of the Exchange Shares and the Cancellation Shares, respectively;

(v) to BRKR, a receipt executed by Invest Shareholders for the Share Exchange Price;

(vi) to BRKR, an excerpt of the entry of Invest in the Commercial Register, which is not older than 5 calendar days, evidencing that Isolde Laukien-Kleiner has resigned from the board of directors of Invest and that Tony Keller is registered as president of the board of directors of Invest and a statement of Isolde Laukien-Kleiner that she has been fully compensated for her services rendered to Invest and that she has no, and validly waives all, claims of whatsoever nature against Invest except for claims under this Swiss Merger Agreement; and

A-3-21

periods prior to the date of the Financial Statements irrespective of the financial period during which such Taxes may become due.

The BRKR Indemnified Party will provide Invest Shareholders with prompt notice of any third-party claim in respect of which indemnification is sought. The failure to provide either such notice will not affect any rights hereunder except to the extent Invest Shareholders are materially prejudiced thereby.

(b) If such claim involves a claim by a Third Party against the BRKR Indemnified Parties, Invest Shareholders may, upon notice to the BRKR Indemnified Parties, assume, through counsel of Invest Shareholders' choosing and at Invest Shareholders' expense, the settlement or defense thereof, and the BRKR Indemnified Parties shall reasonably cooperate with Invest Shareholders in connection therewith; provided, that the BRKR Indemnified Parties may participate in such settlement or defense through counsel chosen by them; provided, further, that if the BRKR Indemnified Parties reasonably determine that representation by the counsel of Invest Shareholders and the BRKR Indemnified Parties may present such counsel with a conflict of interests, then Invest Shareholders shall pay the reasonable fees and expenses of the BRKR Indemnified Parties' counsel. Notwithstanding anything in this Section 10.3 to the contrary, Invest Shareholders may not, without the prior written consent of the BRKR Indemnified Parties, settle or compromise any action or consent to the entry of any judgment, such consent not to be unreasonably withheld. So long as Invest Shareholders are contesting any such claim in good faith, the BRKR Indemnified

A-3-38

Parties shall not pay or settle any such claim without Invest Shareholders' consent, such consent not to be unreasonably withheld. If Invest Shareholders are not contesting such claim in good faith, then the BRKR Indemnified Parties may conduct and control, through counsel of their own choosing and at Invest Shareholders' expense, the settlement or defense thereof, and Invest Shareholders shall cooperate with it in connection therewith. The failure of the BRKR Indemnified Parties to participate in, conduct or control such defense shall not relieve Invest Shareholders of any obligation they may have hereunder.

(c) Notwithstanding anything to the contrary in this Section 10.3, to the extent a claim for which indemnification is sought by BRKR Indemnified Parties relates to Taxes for a taxable period beginning on or before and ending after the Closing Date, Invest Shareholders and BRKR shall jointly control any proceeding in respect of such claim and neither party shall settle or compromise any action or consent to the entry of any judgment with respect thereto without the prior written consent of the other party, such consent not to be unreasonably withheld.

Section 10.4 Calculation of Indemnity Payments. The amount of any Loss for which indemnification is provided under this Article X shall be (a) increased to the extent necessary such that after payment of any net Tax cost by the BRKR Indemnified Parties with respect to the receipt or accrual of indemnity payments hereunder, as increased pursuant to this clause (a), the amount remaining shall be the amount of the indemnity payment prior to any increase pursuant to this clause (a) and (b) reduced by the amount of the net Tax benefit actually realized by the BRKR Indemnified Parties by reason of such Loss (as an illustrative example, clause (b) takes into account on a present value basis any net Tax benefit actually realized by the BRKR Indemnified Party by reason of the indemnified Loss in a Tax jurisdiction or Tax year other than the jurisdiction or year in which such Loss arose).

Section 10.5 Indemnification Amounts.

(a) Notwithstanding any provision to the contrary contained in this Swiss Merger Agreement, Invest Shareholders shall not be obligated to indemnify the BRKR Indemnified Parties for any Losses pursuant to this Article X to the extent they are a result of any claim made pursuant to Section 10.2(a) unless and until the dollar amount of all Losses in the aggregate from claims made pursuant to Section 10.2(a), Section 9.2(a) of the U.S. SPA and Section 9.2(a) of the German SPA exceed $3,250,000, in which case Invest Shareholders will be obligated to indemnify the BRKR Indemnified Parties for the total amount of Losses including any amounts which would otherwise not be required to be paid by reason of this Section 10.5; provided, however, that in no event shall the aggregate indemnification obligations of Invest Shareholders pursuant to Sections 10.2(a), (b) or (c) of this Swiss Merger Agreement, Sections 9.2(a), (b) or (c) of the U.S. SPA, and Sections 9.2(a), (b) or (c) of the German SPA exceed Ninety Two Million Dollars ($92,000,000) (the "Indemnity Cap"); provided, further, that notwithstanding the foregoing, the BRKR Indemnified Parties' right to seek indemnification hereunder for any Losses arising out of (i) criminal activity or fraud (in each case as determined in a final, non-appealable decision by a court of competent jurisdiction) of Invest Shareholders or Invest or (ii) Section 3.8 (Ownership of the Invest Shares), Section 3.9 (Withholding Tax), Section 4.3 (Capitalization of Invest), Section 4.4 (Capitalization of the Subsidiaries; Other Interests) or Section 4.17 (Environmental) shall not be subject to, or limited by, the limits contained in this Section 10.5; provided, further, that with respect to any Losses arising out of Section 3.8 (Ownership of Invest Shares) and Section 3.9 (Withholding Tax), the liability of any Invest Shareholder beyond the Indemnity Cap shall be several and not joint. Notwithstanding the foregoing, no Invest Shareholder shall have any liability under this Article X or otherwise under this Swiss Merger Agreement in excess of the amount set forth opposite such Invest Shareholder's name under the heading "Individual Selling Shareholders' Indemnity Cap" as set forth on Schedule 9.5 to the U.S. SPA.

A-3-39

(b) For the purpose of calculating the amount of any Loss for which a BRKR Indemnified Party is entitled to indemnification under this Swiss Merger Agreement, the amount of each Loss shall be deemed to be an amount net of any insurance proceeds and any indemnity, contribution or other similar payment that has been paid by any insurer or other third party with respect thereto. The reasonable out-of-pocket costs and expenses (including reasonable fees and disbursements of counsel) actually incurred by the BRKR Indemnified Parties in pursuing any insurance proceeds or indemnity, contribution or other similar payment from any insurer or other third party under this Article X shall constitute additional Losses with respect to the matter for which indemnification may be sought hereunder, except to the extent such costs and expenses are paid or reimbursed by such insurer or other third party. In the event that a BRKR Indemnified Party is paid by Invest Shareholders for a Loss for which one or more insurance claims or claims against Third Parties has been or could be made, but for which payment from such insurer or Third Party has not been received, then such BRKR Indemnified Party shall assign, to the extent legally permissible, all such claims to Invest Shareholders for purposes of recouping payment of such Loss. To the extent such assignment should not be legally permissible, the respective BRKR Indemnified Party shall remit any payment received, up to the amount of such Loss, from such insurance claim or Third Party claim to Invest Shareholders.

(c) BRKR shall be entitled to recover Losses from the Indemnity Escrow; provided, however, that the recovery is not limited to the amount in the Indemnity Escrow.

Section 10.6 Exclusive Remedy. BRKR acknowledges and agrees that the indemnification provisions of this Article X shall be the sole and exclusive remedies of BRKR against Invest Shareholders and Invest for any breach by Invest Shareholders or Invest of the representations and warranties in this Swiss Merger Agreement, for any failure by Invest Shareholders or Invest to perform and comply with any covenants and agreements in this Swiss Merger Agreement that are required to be complied with or performed prior to the Closing and for any failure by Invest Shareholders or Invest to perform and comply with any covenants and agreements in this Swiss Merger Agreement, except that if any of the provisions of this Swiss Merger Agreement are not performed in accordance with their terms or are otherwise breached, BRKR shall be entitled to specific performance of the terms thereof in addition to any other remedy at law or equity. Notwithstanding anything contained in this Swiss Merger Agreement to the contrary, BRKR shall retain the right to receive damages or other relief (including equitable relief) against Invest or Invest Shareholders as a result of any criminal activity or fraudulent action (in each case as determined in a final, non-appealable decision by a court of competent jurisdiction) by Invest or Invest Shareholders without regard to any restriction or limitation contained herein. The indemnification obligations contained in this Article X are obligations of Invest Shareholders and not of Invest.

Except as provided in the immediately preceding sentence, no action taken pursuant to this Swiss Merger Agreement will be deemed to constitute a waiver of compliance with any representations, warranties, conditions or covenants contained in this Swiss Merger Agreement and will not operate or be construed as a waiver of any subsequent breach, whether of a similar or dissimilar nature.

Section 11.5 Entire Agreement; Schedules. This Swiss Merger Agreement, the U.S. SPA and the German SPA, which includes the schedules and exhibits hereto and thereto, supersedes any other agreement, whether written or oral, that may have been made or entered into by any party relating to the matters contemplated by this Swiss Merger Agreement and such other agreements and constitutes the entire agreement by and among the Parties relating to these matters.

December 2, 2007

Special Committee of the Board of Directors
Bruker BioSciences Corporation
40 Manning Road
Billerica, MA 01821

Gentlemen:

We understand that Bruker BioSciences Corporation ("BioSciences") intends to enter into a series of agreements pursuant to which BioSciences will acquire the Bruker BioSpin group of companies (the transactions effecting such acquisition, collectively, the "Transaction"), which is comprised of Bruker BioSpin Invest AG ("Invest"), Bruker BioSpin Inc. ("BioSpin U.S."), Bruker Physik GmbH ("Bruker Physik") and Techneon AG ("Techneon" and, together with Invest, BioSpin U.S. and Bruker Physik, "BioSpin").

In order to effect the Transaction, we understand that BioSciences, BioSpin and various other related individuals and entities intend to undertake the following:

•: Dirk D. Laukien, Frank H. Laukien, Isolde Laukien-Kleiner, Joerg C. Laukien, Marc M Laukien and Robyn L. Laukien (collectively, the "Sellers"), BioSciences and BioSpin U.S. intend to enter into a U.S. Stock Purchase Agreement, to be dated as of December 2, 2007 (the "U.S. Stock Purchase Agreement"), pursuant to which the Sellers will sell to BioSciences all of the issued and outstanding capital stock of BioSpin U.S. for an aggregate purchase price of $99,962,514 in cash (the "U.S. Consideration");
•: BioSciences, SciTec GmbH & Co. KG ("SciTec"), Techneon, Bruker Optik GmbH, Bruker Daltonik GmbH, the Sellers and Bruker Physik intend to enter into a German Share Purchase Agreement, to be dated as of December 2, 2007 (the "German Share Purchase Agreement"), pursuant to which the following transactions shall be effected: (i) the acquisition of 25.5% of Bruker Physik's share capital from the Sellers and the acquisition of 61.5% of Bruker Physik's share capital from SciTec for an aggregate of $143,460,000 in cash (the "German Phase I Consideration") by, respectively, BioSciences (or its assignee) (shares in the aggregate representing 50.5% of Bruker Physik's share capital), Bruker Daltonik GmbH (one share representing 18.25% of Bruker Physik's share capital) and Bruker Optik GmbH (one share representing 18.25% of Bruker Physik's share capital), with one share representing 13.0% of Bruker Physik's share capital remaining in the ownership of Techneon, a wholly owned subsidiary of SciTec, and (ii) the subsequent acquisition of 100% of the common shares of Techneon from SciTec by Bruker Physik for $142,540,000 in cash (together with the German Phase I Consideration, the "German Consideration");
•: Bruker Optik GmbH, SciTec and Isolde Laukien-Kleiner intend to enter into the SciTec Real Property Sale and Transfer Agreement, to be dated as of the closing of the Transaction, pursuant to which SciTec and Isolde Laukien-Kleiner will sell to Bruker Optik GmbH certain SciTec real property for an aggregate purchase price of 1,416,250 Euros in cash (the "SciTec Real Property Consideration");
•: BioSciences, Bruker BioSpin Beteiligungs AG, a Swiss stock corporation and a direct, wholly owned subsidiary of BioSciences ("Merger Sub"), the Sellers and Invest intend to enter into a Swiss Agreement and Plan of Merger, to be dated as of December 2, 2007 (the "Swiss Merger Agreement" and collectively with the U.S. Stock Purchase Agreement and the German Share

B-1

Purchase Agreement, the "Purchase Agreements"), pursuant to which BioSciences will acquire Invest by means of a share exchange, share cancellation and reverse subsidiary merger in which Merger Sub will be merged with and into Invest (the "Swiss Merger"), with Invest surviving the Swiss Merger as a direct, wholly owned subsidiary of BioSciences. In connection with the Swiss Merger, BioSciences shall issue to the Sellers 57,544,872 shares (together with the U.S. Consideration, the German Consideration and the SciTec Real Property Consideration, the "Transaction Consideration") of the common stock, par value $0.01 per share, of BioSciences ("BioSciences Common Stock") in consideration for 15,840 shares of Invest and the cancellation of 160 Invest shares;

•: Pursuant to the terms of an agreement by and among BioSciences, the Sellers and Nixon Peabody LLP, a New York limited liability partnership ("Escrow Agent"), to be dated as of the closing of the Transaction (the "Working Capital Escrow Agreement"), BioSciences shall deposit with Escrow Agent on behalf of the Sellers a portion of the U.S. Consideration, to be held by Escrow Agent in an escrow account and released to the Sellers or Purchaser under the terms of the Working Capital Escrow Agreement, as security for any potential post-closing adjustments to the U.S. Consideration pursuant to the U.S. Stock Purchase Agreement; and
•: Pursuant to the terms of an agreement by and among BioSciences, the Sellers and Escrow Agent, to be dated as of the closing of the Transaction (together with the Purchase Agreements and the Working Capital Escrow Agreement, the "Transaction Agreements"), an escrow fund of $92,000,000, to be funded by a portion of the U.S. Consideration, shall be created to serve as security for fulfillment by the Sellers of their indemnity obligations under each of the Purchase Agreements.

As contemplated by the Transaction Agreements, we further understand that Invest will pay a special cash dividend, prior to the closing of the Transaction, of 75,000,000 Swiss Francs in the aggregate to be distributed to holders, as of the relevant record date, of outstanding shares of common stock of Invest (the "Swiss Special Dividend"). We also understand that the Sellers have entered into cash-stock exchange agreements (the "Exchange Agreements") amongst themselves related to the allocation of the Swiss Special Dividend and the Transaction Consideration, which at the time of the closing of the Transaction or within one year thereafter will result in each Sellers' receiving differing proportions of cash and stock Transaction Consideration.

You have provided us with a copy of the Transaction Agreements in substantially final form. We further understand that Dirk D. Laukien, Frank H. Laukien, Isolde Laukien-Kleiner, Joerg C. Laukien, Marc M. Laukien and Robyn L. Laukien collectively own approximately 52% of BioSciences (such parties, collectively with their respective affiliates and associates, the "Affiliated Parties").

You have asked us to render our opinion as to whether the Transaction Consideration is fair, from a financial point of view, to the holders of BioSciences Common Stock, excluding the Affiliated Parties.

In the course of performing our reviews and analyses for rendering this opinion, we have:

•: reviewed drafts of the Transaction Agreements dated as of December 1, 2007;
•: reviewed BioSpin's restated Combined Financial Statements for the years ended December 31, 2004, 2005 and 2006, as audited by Ernst & Young LLP, and its Combined Financial Statements for the nine months ended September 30, 2006 and 2007, as reviewed by Ernst & Young LLP;
•: reviewed BioSciences' Annual Reports to Shareholders and Annual Reports on Form 10-K for the years ended December 31, 2004, 2005 and 2006, its Quarterly Reports on Form 10-Q for the periods ended March 31, 2007, June 30, 2007 and September 30, 2007 and its Current Reports on Form 8-K filed since December 31, 2006;

B-2

•: reviewed certain operating and financial information relating to BioSpin's business and prospects, including projections for the five years ended December 31, 2012, all as prepared and provided to us by BioSpin's management (the "BioSpin Projections");
•: met with certain members of BioSpin's senior management to discuss BioSpin's business, operations, historical financial results and future prospects and the BioSpin Projections;
•: reviewed certain operating and financial information relating to BioSciences' and BioSpin's businesses and prospects, including projections for each of BioSciences and BioSpin for the five years ended December 31, 2012, all as prepared and provided to us by BioSciences' management (the "BioSciences Projections" and "Adjusted BioSpin Projections," respectively, and taken together with the BioSpin Projections, the "Projections");
•: reviewed certain estimates of revenue enhancements, cost savings and other combination benefits expected to result from the Transaction, all as prepared and provided to us by BioSciences' management (collectively, the "Potential Synergies");
•: met with certain members of BioSciences' senior management to discuss BioSciences' and BioSpin's businesses, operations, historical financial results and future prospects, the Projections and the Potential Synergies;
•: reviewed the historical prices, trading multiples and trading volume of the BioSciences Common Stock;
•: reviewed certain publicly available financial data, stock market performance data and trading multiples of companies which we deemed generally comparable to BioSciences and BioSpin;
•: reviewed the terms of certain relevant mergers and acquisitions involving companies which we deemed generally comparable to BioSpin;
•: performed discounted cash flow analyses based on the BioSciences Projections, the Adjusted BioSpin Projections and the pro forma combined projections of BioSciences and BioSpin including the Potential Synergies;
•: reviewed the pro forma financial results, financial condition and capitalization of BioSciences, giving effect to the Transaction; and
•: conducted such other studies, analyses, inquiries and investigations as we deemed appropriate.

We have relied upon and assumed, without independent verification, the accuracy and completeness of the financial and other information provided to or discussed with us by BioSciences and BioSpin or obtained by us from public sources, including, without limitation, the Projections and the Potential Synergies. With respect to the Projections and the Potential Synergies, we have relied on representations that they have been reasonably prepared on bases reflecting the best currently available estimates and judgments of the senior management of BioSciences and BioSpin, as the case may be, as to the expected future performance of BioSciences and BioSpin. We have not assumed any responsibility for the independent verification of any such information or of the Projections and the Potential Synergies. We express no view or opinion as to the Projections and the Potential Synergies and the assumptions upon which they are based and we have further relied upon the assurances of the senior management of BioSciences and BioSpin, as the case may be, that they are unaware of any facts that would make the information, the Projections and the Potential Synergies incomplete or misleading.

In arriving at our opinion, we have not performed or obtained any independent appraisal of the assets or liabilities (contingent or otherwise) of BioSciences and BioSpin, nor have we been furnished with any such appraisals. We have assumed that the Transaction will be consummated in a timely manner and in accordance with the terms of the Transaction Agreements without any limitations, restrictions, conditions, amendments or modifications, regulatory or otherwise, that collectively would

B-3

have a material effect on BioSciences or BioSpin. We are not legal, regulatory, tax or accounting experts and have relied on the assessments made by BioSciences and BioSpin and their respective advisors with respect to such issues. We have also assumed that the form of the Transaction Agreements will be substantially similar to the draft reviewed by us.

We do not express any opinion as to the price or range of prices at which the BioSciences Common Stock may trade subsequent to the announcement or consummation of the Transaction.

We have acted as a financial advisor to the Special Committee of the Board of Directors of BioSciences in connection with the Transaction and will receive a customary fee for such services, a substantial portion of which is contingent on successful consummation of the Transaction. A portion of our compensation is payable upon delivery of this letter and may be credited against the fee payable upon consummation of the Transaction. In addition, BioSciences has agreed to reimburse us for certain expenses and to indemnify us against certain liabilities arising out of our engagement.

Bear, Stearns & Co. Inc. ("Bear Stearns") has previously been engaged by BioSciences to provide certain investment banking and other services on matters unrelated to the Transaction for which we have received customary fees. Bear Stearns may seek to provide BioSciences and its respective affiliates with certain investment banking and other services unrelated to the Transaction in the future.

Consistent with applicable legal and regulatory requirements, Bear Stearns has adopted certain policies and procedures to establish and maintain the independence of Bear Stearns' research departments and personnel. As a result, Bear Stearns' research analysts may hold views, make statements or investment recommendations and/or publish research reports with respect to BioSciences, the Transaction and other participants in the Transaction that differ from the views of Bear Stearns' investment banking personnel.

In the ordinary course of business, Bear Stearns and its affiliates may actively trade (for its own account and for the accounts of its customers) certain equity and debt securities, bank debt and/or other financial instruments issued by BioSciences and its affiliates, as well as derivatives thereof, and, accordingly, may at any time hold long or short positions in such securities, bank debt, financial instruments and derivatives.

It is understood that this letter is intended for the benefit and use of the Special Committee of the Board of Directors of BioSciences in connection with its consideration of the Transaction. This letter is not to be used for any other purpose, or be reproduced, disseminated, quoted from or referred to at any time, in whole or in part, without our prior written consent; provided, however, that this letter may be included in its entirety in any proxy statement to be distributed to the holders of BioSciences Common Stock in connection with the Transaction.

ANNEX D

BRUKER BIOSCIENCES CORPORATION
AMENDED AND RESTATED
2000 STOCK OPTION PLAN

1. Purpose of the Plan.

This stock option plan (the "2000 Stock Option Plan") is intended to encourage ownership of the stock of Bruker BioSciences Corporation (f/k/a Bruker Daltonics Inc.) (the "Company") by management, employees, directors, consultants and advisors ("Optionees") of the Company and its subsidiaries, to induce qualified personnel to enter and remain in the employ of the Company or its subsidiaries and otherwise to provide additional incentive for Optionees to promote the success of its business.

2. Stock Subject to the 2000 Stock Option Plan.

(a) The total number of shares of the authorized but unissued or Treasury shares of the common stock, $.01 par value, of the Company ("Common Stock") for which options may be granted under the 2000 Stock Option Plan shall not exceed ten million (10,000,000) shares, subject to adjustment as provided in Section 12 hereof.

(b) If an option granted hereunder shall expire or terminate for any reason without having vested fully or having been exercised in full, the unvested and/or unpurchased shares subject thereto shall again be available for subsequent option grants under the 2000 Stock Option Plan.

(c) Stock issuable upon exercise of an option granted under the 2000 Stock Option Plan may be subject to such restrictions on transfer, repurchase rights (but not to exceed 20% of the stock issuable upon exercise of options granted under the 2000 Stock Option Plan) or other restrictions as shall be determined by the Board of Directors of the Company (the "Board").

(d) Notwithstanding any other provision of this Plan to the contrary, the Compensation Committee of the Board shall have the right, in its sole discretion, to allocate and grant up to twenty percent (20%) of the Common Stock authorized to be granted as options hereunder as restricted stock to employees of the Company on such terms and conditions and pursuant to such restricted stock agreements as the Compensation Committee, in its discretion, shall deem appropriate.

3. Administration of the 2000 Stock Option Plan.

The 2000 Stock Option Plan shall be administered by the Board or a Stock Option Committee (the "Compensation Committee") consisting of two or more persons appointed to such Compensation Committee from time to time by the Board; provided, however, that (i) to the extent necessary in order to permit officers and directors of the Company to be exempt from the provisions of Section 16(b) of the 1934 Act with respect to transactions pursuant to the 2000 Stock Option Plan, each of such persons shall be a "Non-Employee Director" within the meaning of Rule 16b-3 ("Rule 16b-3") promulgated by the Securities and Exchange Commission under the Securities Exchange Act of 1934, as amended (the "1934 Act") and (ii) if such qualification is deemed necessary in order for the grant or exercise of awards made under the 2000 Stock Option Plan to qualify for any tax or other material benefit to participants of the Company under applicable regulations under Section 162(m) of the Code, each of such persons shall be an "outside director" (as defined in applicable regulations thereunder). The term "Compensation Committee" shall, for all purposes of the 2000 Stock Option Plan be deemed to refer to the Board if the Board is administering the 2000 Stock Option Plan. If the 2000 Stock Option Plan is administered by a Compensation Committee, the Compensation Committee shall from time to time select a Chairman from among its members and shall adopt such rules and regulations as it shall deem appropriate concerning the holding of meetings and the administration of the 2000 Stock Option Plan.

D-1

A majority of the entire Compensation Committee shall constitute a quorum and the actions of a majority of the members of the Compensation Committee present at a meeting at which a quorum is present, or actions approved in writing by all of the members of the Compensation Committee, shall be the actions of the Compensation Committee; provided, however, that if the Compensation Committee consists of only two members, both shall be required to constitute a quorum and to act at a meeting or to approve actions in writing. Except as otherwise expressly provided in the 2000 Stock Option Plan, the Compensation Committee shall have all powers with respect to the administration of the 2000 Stock Option Plan, including, without limitation, full power and authority to interpret the provisions of the 2000 Stock Option Plan and any option agreement grated hereunder, and to resolve all questions arising under the 2000 Stock Option Plan. All decisions of the Compensation Committee shall be conclusive and binding on all participants in the 2000 Stock Option Plan.

4. Type of Options.

Options granted pursuant to the 2000 Stock Option Plan shall be authorized by action of the Compensation Committee and may be designated as either incentive stock options meeting the requirements of Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"), or non-qualified options which are not intended to meet the requirements of such Section 422 of the Code, the designation to be in the sole discretion of the Compensation Committee. The 2000 Stock Option Plan shall be administered by the Compensation Committee in such manner as to permit options granted as incentive stock options to qualify as incentive stock options under the Code.

5. Eligibility.

(a) As required by U.S. law, incentive stock options shall only be granted to Optionees who are employees. As a result, options designated as incentive stock options shall, subject to the limitation on amounts of more than 10% of the combined voting power of the Company as designated in Section 5(e), be granted only to key employees (including officers and directors who are also employees) of the Company or any of its subsidiaries, including subsidiaries which become such after adoption of the 2000 Stock Option Plan.

(b) The law permits more flexibility for the grant of non-qualified stock options. Accordingly, options designated as non-qualified options may be granted to officers, employees, consultants, advisors and directors of the Company or of any of its subsidiaries, including subsidiaries which become such after adoption of the 2000 Stock Option Plan.

(c) As used herein, "subsidiary" or "subsidiaries" shall be as defined in Section 424 of the Code and the Treasury Regulations promulgated thereunder (the "Regulations").

(d) The Compensation Committee shall, from time to time, at its sole discretion, select from such eligible persons those to whom options shall be granted and shall determine the number of shares to be subject to each option. In determining the eligibility of a person to be granted an option, as well as in determining the number of shares to be granted to any person, the Compensation Committee in its sole discretion shall take into account the position and responsibilities of the person being considered, the nature and value to the Company or its subsidiaries of his or her service and accomplishments, his or her present and potential contribution to the success of the Company or its subsidiaries, and such other factors as the Compensation Committee may deem relevant.

(e) As required by law, no option designated as an incentive stock option shall be granted to any employee of the Company or any subsidiary if such employee owns, immediately prior to the grant of an option, stock possessing more than 10% of the total combined voting power of all classes of stock of the Company or of a parent or a subsidiary, unless the purchase price for the stock under such option shall be at least 110% of its fair market value at the time such option is granted and the option, by its terms, shall not be exercisable more than five years from the date it is granted. In determining the stock ownership under this paragraph, the provisions of Section 424(d) of the Code shall be controlling.

D-2

(f) In determining the fair market value under this paragraph, the provisions of Section 7 hereof shall apply.

(g) Subject to the provisions of Section 12 relating to adjustments upon changes in the shares of Common Stock, no employee shall be eligible to be granted Options covering more than 100,000 shares of Common Stock during any calendar year.

6. Option Agreement.

Each option shall be evidenced by an option agreement (the "Agreement") duly executed on behalf of the Company and by the Optionee to whom such option is granted, which Agreement shall comply with and be subject to the terms and conditions of the 2000 Stock Option Plan. The Agreement may contain such other terms, provisions and conditions which are not inconsistent with the 2000 Stock Option Plan as may be determined by the Compensation Committee; provided that (a) options designated as incentive stock options shall meet all of the conditions for incentive stock options as defined in Section 422 of the Code; (b) the vesting schedule contained in the form of incentive stock option agreement approved by the Board shall not be altered by the Compensation Committee for any grant of an incentive stock option; and (c) the vesting schedule contained in the form of non-qualified stock option agreement approved by the Board shall be the recommended vesting schedule for the grant of non-qualified stock options by the Compensation Committee but may be altered by the Compensation Committee. The date of grant of an option shall be as determined by the Compensation Committee. More than one option may be granted to an individual.

7. Option Price.

The option price or prices of shares of the Company's Common Stock for options designated as non-qualified stock options shall be as determined by the Compensation Committee, but in no event shall the option price of a non-qualified stock option be less than 50% of the fair market value of such Common Stock at the time the option is granted, as determined by the Compensation Committee. The option price or prices of shares of the Company's Common Stock for incentive stock options shall be not less than the fair market value of such Common Stock at the time the option is granted as determined by the Compensation Committee in accordance with the Regulations promulgated under Section 422 of the Code. If such shares are then listed on any national securities exchange, the fair market value shall be the mean between the high and low sales prices, if any, on the largest such exchange on the date of the grant of the option or, if none, shall be determined by taking a weighted average of the means between the highest and lowest sales prices on the nearest date before and the nearest date after the date of grant in accordance with Treasury Regulations Section 25.2512-2. If the shares are not then listed on any such exchange, the fair market value of such shares shall be the mean between the high and low sales prices, if any, as reported in the National Association of Securities Dealers Automated Quotation National Market ("NASDAQ/NM") for the date of the grant of the option, or, if none, shall be determined by taking a weighted average of the means between the highest and lowest sales on the nearest date before and the nearest date after the date of grant in accordance with Treasury Regulations Section 25.2512-2. If the shares are not then either listed on any such exchange or quoted in NASDAQ/NM, the fair market value shall be the mean between the average of the "Bid" and the average of the "Ask" prices, if any, as reported in the National Daily Quotation Service for the date of the grant of the option, or, if none, shall be determined by taking a weighted average of the means between the highest and lowest sales prices on the nearest date before and the nearest date after the date of grant in accordance with Treasury Regulations Section 25.2512-2. If the fair market value cannot be determined under the preceding three sentences, it shall be determined in good faith by the Compensation Committee.

D-3

8. Manner of Payment; Manner of Exercise.

(a) Options granted under the 2000 Stock Option Plan may provide for the payment of the exercise price, as determined by the Compensation Committee and as set forth in the Option Agreement, by delivery of (i) cash or a check payable to the order of the Company in an amount equal to the exercise price of such options, (ii) shares of Common Stock of the Company owned by the optionee having a fair market value equal in amount to the exercise price of the options being exercised, (iii) any combination of (i) and (ii), provided, however, that payment of the exercise price by delivery of shares of Common Stock of the Company owned by such optionee may be made only if such payment does not result in a charge to earnings for financial accounting purposes as determined by the Compensation Committee or (iv) payment may also be made by delivery of a properly executed exercise notice to the Company, together with a copy of irrevocable instruments to a broker to deliver promptly to the Company the amount of sale or loan proceeds to pay the exercise price. To facilitate clause (iv) above, the Company may enter into agreements for coordinated procedures with one or more brokerage firms.

(b) To the extent that the right to purchase shares under an option has accrued and is in effect, options may be exercised in full at one time or in part from time to time, by giving written notice, signed by the Optionee exercising the option, to the Company, stating the number of shares with respect to which the option is being exercised, accompanied by payment in full for such shares as provided in subparagraph (a) above. Upon such exercise, delivery of a certificate for paid-up non-assessable shares shall be made at the principal office of the Company to the Optionee exercising the option at such time, during ordinary business hours, not more than thirty (30) days from the date of receipt of the notice by the Company, as shall be designated in such notice, or at such time, place and manner as may be agreed upon by the Company and the person or persons exercising the option. Upon exercise of the option and payment as provided above, the Optionee shall become a shareholder of the Company as to the Shares acquired upon such exercise.

9. Exercise of Options.

Each option granted under the 2000 Stock Option Plan shall, subject to Section 6, Section 10(b) and Section 12 hereof, be exercisable at such time or times and during such period as determined by the Compensation Committee which shall be set forth in the Agreement; provided, however, that no option granted under the 2000 Stock Option Plan shall have a term in excess of ten (10) years from the date of grant.

To the extent that an option to purchase shares is not exercised by an Optionee when it becomes initially exercisable, it shall not expire but shall be carried forward and shall be exercisable, on a cumulative basis, until the expiration of the exercise period. No partial exercise may be made for less than fifty (50) full shares of Common Stock.

Notwithstanding the foregoing, the Compensation Committee may in its discretion accelerate the exerciseability of any option subject to such terms and conditions as the Compensation Committee deems necessary and appropriate.

10. Term of Options; Exerciseability.

(a) Term.

(1) Each option shall expire not more than ten (10) years from the date of the granting thereof, but shall be subject to earlier termination as herein provided.

(2) Except as otherwise provided in this Section 10, an option granted to any employee who ceases to be an employee of the Company, or an option granted to any other Optionee who ceases to have the same relationship with the Company or one of its subsidiaries which was in effect on the date the option was granted, shall terminate immediately on the date such Optionee ceases to be an

D-4

employee, or ceases to have such relationship with the Company or one of its subsidiaries, or on the date on which the option expires by its terms, whichever occurs first.

(3) If such termination of employment or relationship is because the Optionee has become permanently disabled (within the meaning of Section 22(e)(3) of the Code), such option shall terminate thirty (30) days after the date such Optionee ceases to be an employee or to have such relationship, or on the date on which the option expires by its terms, whichever occurs first.

(4) In the event of the death of any Optionee, any option granted to such Optionee shall terminate ninety (90) days after the date of death, or on the date on which the option expires by its terms, whichever occurs first.

(5) Notwithstanding subparagraphs (2), (3) and (4) above, the Compensation Committee shall have the authority to extend the expiration date of any outstanding option in circumstances in which it deems such action to be appropriate, provided that no such extension shall extend the term of an option beyond the date on which the option would have expired if no termination of the Optionee's employment or relationship with the Company or its subsidiary had occurred.

(b) Exerciseability.

An option granted to an Optionee who ceases to be an employee, or ceases to have the same relationship with the Company or one of its subsidiaries which was in existence on the date the option was granted shall be exercisable only to the extent that the right to purchase shares under such option has accrued and is in effect on the date such Optionee ceases to be an employee, or ceases to have such relationship with the Company or one of its subsidiaries.

11. Options Not Transferable.

The right of any Optionee to exercise any option granted to him or her shall not be assignable or transferable by such Optionee otherwise than by will or the laws of descent and distribution, and any such option shall be exercisable during the lifetime of such Optionee only by him or her. Any option granted under the 2000 Stock Option Plan shall be null and void and without effect upon the bankruptcy of the Optionee to whom the option is granted, or upon any attempted assignment or transfer, except as herein provided, including without limitation any purported assignment, whether voluntary or by operation of law, pledge, hypothecation or other disposition, attachment, divorce, trustee process or similar process, whether legal or equitable, upon such option.

12. Recapitalizations, Reorganizations and the Like.

(a) In the event that the outstanding shares of the Common Stock of the Company are changed into or exchanged for a different number or kind of shares or other securities of the Company or of another corporation by reason of any reorganization, merger, consolidation, recapitalization, reclassification, stock split-up, combination of shares, or dividends payable in capital stock, appropriate adjustment shall be made in the number and kind of shares as to which options may be granted under the 2000 Stock Option Plan and as to which outstanding options or portions thereof then unexercised shall be exercisable, to the end that the proportionate interest of the Optionee shall be maintained as before the occurrence of such event; such adjustment in outstanding options shall be made without change in the total price applicable to the unexercised portion of such options and with a corresponding adjustment in the option price per share.

(b) In addition, unless otherwise determined by the Board in its sole discretion, in the case of any (i) sale or conveyance to another entity of all or substantially all of the property and assets of the Company, including, without limitation, by way of merger or consolidation, or (ii) Change in Control (as hereinafter defined) of the Company, the purchaser(s) of the Company's assets or stock may, in his, her or its discretion, deliver to the Optionee the same kind of consideration that is delivered to the shareholders of the Company as a result of such sale, conveyance or Change in Control, or the Board

D-5

may cancel all outstanding options in exchange for consideration in cash or in kind which consideration in both cases shall be equal in value to the value of those shares of stock or other securities the Optionee would have received had the option been exercised (to the extent then exercisable) and no disposition of the shares acquired upon such exercise been made prior to such sale, conveyance or Change in Control, less the option price therefor. Upon receipt of such consideration by the Optionee, his or her option shall immediately terminate and be of no further force and effect. The value of the stock or other securities the Optionee would have received if the option had been exercised shall be determined in good faith by the Board, and in the case of shares of the Common Stock of the Company, in accordance with the provisions of Section 7 hereof. The Board shall also have the power and right to accelerate the exerciseability of any options, notwithstanding any limitations in this 2000 Stock Option Plan or in the Agreement upon such a sale, conveyance or Change in Control. Upon such acceleration, any options or portion thereof originally designated as incentive stock options that no longer qualify as incentive stock options under Section 422 of the Code as a result of such acceleration shall be redesignated as non-qualified stock options. A "Change in Control" shall be deemed to have occurred if any person, or any two or more persons acting as a group, and all affiliates of such person or persons, who prior to such time owned less than twenty percent (20%) of the then outstanding Common Stock of the Company, shall acquire, whether by purchase, exchange, tender offer, merger, consolidation or otherwise, such additional shares of the Company's Common Stock in one or more transactions, or series of transactions, such that following such transaction or transactions, such person or group and affiliates beneficially own at least fifty percent (50%) of the Company's Common Stock outstanding.

(c) Upon dissolution or liquidation of the Company, all options granted under this 2000 Stock Option Plan shall terminate, but each Optionee (if at such time in the employ of or otherwise associated with the Company or any of its subsidiaries) shall have the right, immediately prior to such dissolution or liquidation, to exercise his or her option to the extent then exercisable.

(d) No fraction of a share shall be purchasable or deliverable upon the exercise of any option, but in the event any adjustment hereunder of the number of shares covered by the option shall cause such number to include a fraction of a share, such fraction shall be adjusted to the nearest smaller whole number of shares.

13. No Special Employment or Other Rights.

Nothing contained in the 2000 Stock Option Plan or in any option granted under the Plan shall confer upon any Optionee right with respect to the continuation of his or her employment or other relationship by the Company (or any subsidiary) or interfere in any way with the right of the Company (or any subsidiary), subject to the terms of any separate employment or other agreement, at any time to terminate such employment or other relationship or to increase or decrease the compensation of the option holder from the rate in existence at the time of the grant of an option. Whether an authorized leave of absence, or absence in military or government service, shall constitute termination of employment or another relationship shall be determined by the Compensation Committee at the time.

14. Withholding.

The Company's obligation to deliver shares upon the exercise of any option granted under the 2000 Stock Option Plan and any payments or transfers under Section 12 hereof shall be subject to the Optionee's satisfaction of all applicable Federal, state and local income, excise, employment and any other tax withholding requirements. All non-U.S. Optionees must pay all applicable employee and employers wage and other withholding taxes in advance of receiving shares upon exercise of any vested option.

D-6

15. Restrictions on Issue of Shares.

(a) Notwithstanding the provisions of Section 8, the Company may delay the issuance of shares covered by the exercise of an option and the delivery of a certificate for such shares until one of the following conditions shall be satisfied:

(i) The shares with respect to which such option has been exercised are at the time of the issue of such shares effectively registered or qualified under applicable Federal and state securities acts now in force or as hereafter amended; or

(ii) Counsel for the Company shall have given an opinion, which opinion shall not be unreasonably conditioned or withheld, that such shares are exempt from registration and qualification under applicable Federal and state securities acts now in force or as hereafter amended.

(b) It is intended that all exercises of options shall be effective, and the Company shall use its best efforts to bring about compliance with the above conditions within a reasonable time, except that the Company shall be under no obligation to qualify shares or to cause a registration statement or a post-effective amendment to any registration statement to be prepared for the purpose of covering the issue of shares in respect of which any option may be exercised, except as otherwise agreed to by the Company in writing.

16. Purchase for Investment; Rights of Holder on Subsequent Registration.

Unless the shares to be issued upon exercise of an option granted under the 2000 Stock Option Plan have been effectively registered under the Securities Act of 1933, as now in force or hereafter amended, the Company shall be under no obligation to issue any shares covered by any option unless the Optionee, in whole or in part, shall give a written representation and undertaking to the Company which is satisfactory in form and scope to counsel for the Company and upon which, in the opinion of such counsel, the Company may reasonably rely, that he or she is acquiring the shares issued pursuant to such exercise of the option for his or her own account as an investment and not with a view to, or for sale in connection with, the distribution of any such shares, and that he or she will make no transfer of the same except in compliance with any rules and regulations in force at the time of such transfer under the Securities Act of 1933, or any other applicable law, and that if shares are issued without such registration, a legend to this effect may be endorsed upon the securities so issued. In the event that the Company shall, nevertheless, deem it necessary or desirable to register under the Securities Act of 1933 or other applicable statutes any shares with respect to which an option shall have been exercised, or to qualify any such shares for exemption from the Securities Act of 1933 or other applicable statutes, then the Company may take such action and may require from each Optionee such information in writing for use in any registration statement, supplementary registration statement, prospectus, preliminary prospectus or offering circular as is reasonably necessary for such purpose and may require reasonable indemnity to the Company and its officers and directors and controlling persons from such holder against all losses, claims, damages and liabilities arising from such use of the information so furnished and caused by any untrue statement of any material fact therein or caused by the omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which they were made.

17. Modification of Outstanding Options.

The Board may authorize the amendment of any outstanding option with the consent of the Optionee when and subject to such conditions as are deemed to be in the best interests of the Company and in accordance with the purposes of this 2000 Stock Option Plan.

D-7

18. Approval of Stockholders.

The 2000 Stock Option Plan shall be subject to approval by the vote of stockholders holding at least a majority of the voting stock of the Company present, or represented, and entitled to vote at a duly held stockholders' meeting, or by written consent of the stockholders as provided for under applicable state law, within twelve (12) months after the adoption of the 2000 Stock Option Plan by the Board of Directors and shall take effect as of the date of adoption by the Board of Directors upon such approval. The Compensation Committee may grant options under the 2000 Stock Option Plan prior to such approval, but any such option shall become effective as of the date of grant only upon such approval and, accordingly, no such option may be exercisable prior to such approval.

19. Termination and Amendment.

Unless sooner terminated as herein provided, the 2000 Stock Option Plan shall terminate ten (10) years from the date upon which the 2000 Stock Option Plan was duly adopted by the Board. The Board may at any time terminate the 2000 Stock Option Plan or make such modification or amendment thereof as it deems advisable; provided, however, that except as provided in this Section 19, the Board may not, without the approval of the stockholders of the Company obtained in the manner stated in Section 18, increase the maximum number of shares for which options may be granted or change the designation of the class of persons eligible to receive options under the 2000 Stock Option Plan, or make any other change in the 2000 Stock Option Plan which requires stockholder approval under applicable law or regulations.

20. Reservation of Stock.

The Company shall at all times during the term of the 2000 Stock Option Plan reserve and keep available such number of shares of stock as will be sufficient to satisfy the requirements of the 2000 Stock Option Plan and shall pay all fees and expenses necessarily incurred by the Company in connection therewith.

21. Limitation of Rights in the Option Shares.

An Optionee shall not be deemed for any purpose to be a stockholder of the Company with respect to any of the options except to the extent that the option shall have been exercised with respect thereto and, in addition, a certificate shall have been issued theretofore and delivered to the Optionee.

22. Notices.

Any communication or notice required or permitted to be given under the 2000 Stock Option Plan shall be in writing, and mailed by registered or certified mail or delivered by hand, if to the Company, to its principal place of business, attention: Treasurer, and, if to an Optionee, to the address as appearing on the records of the Company.

2.: Review and approve annually the corporate goals and objectives relevant to the compensation of the Chief Executive Officer and all other officers of the Company (as such term is defined under Rule 16a-1 promulgated under the Securities Exchange Act of 1934) (collectively, the "Executive Officers").
3.: Review and evaluate annually the performance of the Company's Executive Officers in light of the goals and objectives established in accordance with Paragraph 1 above, and determine, set and approve, pursuant to the Committee's sole authority, the individual elements of the Executive Officers' total compensation based on such reviews and evaluations. Specifically:

Annual Salaries. In determining the annual base salaries for Executive Officers, the Committee considers, in particular, the Executive Officers' level of responsibility, experience and potential as well as the needs of the Company. Base salaries paid by other companies in the Company's industry for comparable positions may also be considered. If benchmark comparisons are made in determining the annual base salaries for Executive Officers, the Committee will disclose in its annual report on executive compensation the names of the peer group companies used in such comparison.

Annual Cash Incentive Awards. In determining the annual incentive awards in the form of performance-based cash bonuses for the Chief Executive Officer and the Company's other Executive Officers, management's success in meeting the Company's financial and strategic goals is a factor the Committee deems relevant. These performance-based incentives are capped and are tied to the achievement of certain performance-based operational measures that reflect both business and individual accomplishments. In setting performance measures,

E-2

the Committee considers a variety of qualitative and quantitative performance metrics. Quantitative considerations include such items as revenue and profit growth, net income, cash flow and cash management, return on equity, economic value added, cost of capital, return on invested operating capital, margins, debt reduction, cost containment and market share. Qualitative considerations include such items as leadership, succession planning, customer satisfaction, product quality, legal compliance, ethics and the promotion of a culture of integrity at all levels of the Company and employee development.

Stock Incentives. In determining the long-term incentive component of the Company's compensation, which is designed to provide long-term incentives to Executive Officers and other employees, to encourage the Executive Officers and other employees to remain with the Company and to enable optionees generally to develop and maintain a long-term stock ownership position in the Company's common stock and in turn motivate the recipient to focus on long-term enhancement in stockholder value, the Committee considers the Company's performance and relative stockholder return, the value of similar incentive awards to comparable executives at comparable companies, the awards given to the Company's Executive Officers in the past, an employee's individual initiative, achievement of objectives, qualitative assessment of performance years and such other factors as the Committee deems relevant.

Review of Performance Incentive Compensation. The Committee is especially critical in its review and award of incentive compensation based on achieving financial targets because such compensation could act as an improper motivation with respect to financial reporting and related matters. In an effort to reduce potential abuses associated with such awards, the Committee will be particularly cautious in awarding compensation which is tied to the achievement of financial targets. The Committee will have an appropriate dialog within the Committee with respect to any such possible awards with a particular emphasis on the appropriateness of the award in the specific circumstances, giving due consideration to the position of the potential recipient. For example, for a chief executive officer who is typically not involved in the financial reporting process, such an award may be more appropriate than for a person, such as the chief financial officer, who is directly involved in the financial reporting process. In any event, to the extent the Committee does choose to make any such awards, the Committee will be careful to select appropriate performance metrics in advance and document them sufficiently.

4.: Review and discuss with management the Company's annual Compensation Discussion and Analysis and, based on the review and discussions, determine whether to recommend to the Board of Directors that the Compensation Committee Discussion and Analysis be included in the Company's annual report on Form 10-K and, as applicable, the Company's proxy or information statement.
5.: Review and approve any special or supplemental benefits for the Company's Executive Officers.
6.: Review the overall compensation strategy and the individual elements of total compensation for the senior management of the Company.
7.: Review the overall compensation and benefits strategy for all non-executive employees of the Company to ensure consistency with the Company's stated compensation strategy.
8.: Interpret and administer the Company's 2000 Stock Plan and such other equity-based plans as may be in effect from time to time (the "Plans") and approve changes to such Plans or, where necessary, recommend changes to such plans for approval by the Board or the Company's

E-3

stockholders. Undertake such actions and make such determinations and decisions as it deems necessary and appropriate to carry out the Plans' intent, including:

a.: Selecting employees, officers and non-employee directors to receive awards;
b.: Determining the number of shares to be covered by each award;
c.: Deciding the type of award or awards to be made to each participant and the terms and conditions applicable to each such award;
d.: Entering into agreements evidencing awards made under the Plans and their respective terms and conditions; and
e.: Establishing, maintaining and rescinding rules and regulations relating to the Plans.

In making specific grants to Executive Officers, the Committee evaluates each Executive Officer's total equity compensation package. The Committee generally reviews the option holdings of each of the Executive Officers including vesting and exercise price and the then current value of such unvested options.

9.: Review and make recommendations to the Board concerning policies or guidelines with respect to employment agreements, severance arrangements, change-in-control agreements, or arrangements involving Executive Officers and directors of the Company.
10.: Review annually, in conjunction with the Chairman of the Board of Directors of the Company, the compensation of the Board of Directors of the Company and recommend any changes thereto to the Board of Directors of the Company. The report to the Board of Directors of the Company on this issue will occur each year at the March meeting of the Board of Directors.
11.: At least bi-annually, or more frequently if necessary to comply with the regulations of the NASDAQ or any other statute or regulation applicable to this Committee, review its own performance, and review and reassess the adequacy of this Charter and recommend any proposed changes to the Board of Directors for its approval.
