To the Board of Directors and Shareholder of

In our opinion, the accompanying balance sheets and the related statements of
operations, of shareholder's equity and of cash flows present fairly, in all
material respects, the financial position of General Precision, Inc. (the
"Company") at June 30, 2001 and December 31, 2000 and the results of its
operations and its cash flows for the period from January 1, 2001 through June
30, 2001 and for the year ended December 31, 2000, in conformity with accounting
principles generally accepted in the United States of America. These financial
statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these statements in accordance with
auditing standards generally accepted in the United States of America, which
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
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.

           critical processes and manufacturing applications for the
           semiconductor, disc-drive, pharmaceutical and aerospace industries.
           The Company was incorporated in California in 1988. All issued and
           outstanding stock of the Company is held by a family trust of which
           the benefactors are the president and the chief financial officer of
           the Company.

2.         SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

           Use of Estimates

           In the normal course of preparing financial statements in conformity
           with accounting principles generally accepted in the United States of
           America, management is required 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 the reported amounts of revenues and
           expenses during the reporting period. Actual results could differ
           from those estimates.

           Cash and Cash Equivalents

           Cash equivalents consist primarily of certificates of deposit and
           other short term, highly liquid investments with original maturities
           of three months or less and are stated at cost, which approximates
           fair value. Certificates of deposit at June 30, 2001 and December 31,
           2000 were $4,017,878 and $1,955,233, respectively.

           Inventories

           Inventories are stated at the lower of cost (first in, first out) or
           market.

           Long-Lived Assets

           The Company reviews its long-lived assets for impairment whenever
           events or changes in circumstances indicate the carrying amount of
           such assets may not be recoverable. Recoverability of these assets is
           determined by comparing the forecasted undiscounted cash flows
           attributable to such assets to their carrying value. If the carrying
           value of the assets exceeds the forecasted undiscounted cash flows,
           then the assets are written down to their fair value. Fair value is
           determined based on discounted cash flows or appraised values,
           depending upon the nature of the assets. To date, no such impairments
           have been recorded.

           Property and Equipment

           Property and equipment are stated at cost less accumulated
           depreciation and amortization. Depreciation and amortization are
           computed using the straight-line method based upon the estimated
           useful lives of the assets or lease terms, if shorter. Management
           evaluates useful lives regularly in order to determine recoverability
           in light of current market and technological conditions. Depreciation
           and amortization periods by asset category are as follows:



                                                                                   
                     Machinery and equipment                                               5 years
                     Office furniture and equipment                                        7 years
                     Computer equipment and software                                       3 years
                     Leasehold improvements                                               15 years
                     Autos and trucks                                                      5 years
                     Assets held under capital lease                                  Shorter of lease term or useful life



           Maintenance and repairs are charged to expense as incurred. Upon the
           sale or retirement of property and equipment, the accounts are
           relieved of the cost and the related accumulated depreciation or
           amortization, with any resulting gain or loss included in the
           Statements of Operations.

           Revenue Recognition

           Revenues from sales of products are recognized upon the transfer of
           title, generally at the time of shipment, to the customer's final
           site and satisfaction of related Company obligations, if any,
           provided that persuasive evidence of an arrangement exists, the fee
           is fixed and determinable and collectibility is deemed probable.
           Revenues associated with installation services, if provided, are
           deferred based on the fair value of such services and are recognized
           upon completion. Installation services are accounted for as a
           separate element based on the customer's obligation to pay the
           contract price upon shipment of the related equipment and the fact
           that such services are not essential to the functionality of the
           related equipment, are available from other vendors and can be
           purchased unaccompanied by other elements.

           Cost of Revenues

           Cost of revenues consists primarily of labor, raw materials, overhead
           and shipping and handling costs.

           Advertising Expenses

           Advertising costs are expensed as incurred. For the six-month period
           ended June 30, 2001 and the year ended December 31, 2000, advertising
           expenses were $102,902 and $119,820, respectively.

           Income Taxes

           The Company accounts for income taxes in accordance with Statement of
           Financial Accounting Standards No. 109, "Accounting for Income Taxes"
           ("SFAS 109"). This statement requires the asset and liability method
           of accounting for income taxes. Under the asset and liability method
           of SFAS 109, deferred tax assets and liabilities are recognized for
           the future tax consequences attributable to differences between the
           financial statement carrying amounts of existing assets and
           liabilities and their respective tax bases.

           The Company has elected to be taxed under the provisions of the
           Subchapter S for federal and state income tax purposes. In accordance
           with the federal provisions, corporate earnings flow through and are
           taxed solely at the shareholder level. Under the provisions of the
           California franchise tax laws, S Corporation earnings are assessed a
           1.5% surtax at the corporate level and flow through to the
           shareholder to be taxed at the individual level.

           The provision for taxes in the accompanying Statements of Operations
           is for California S corporation franchise taxes. There are no
           material deferred tax assets or liabilities.

           Recent Accounting Pronouncements

           In June 1998, the Financial Accounting Standards Board ("FASB")
           issued SFAS No. 133 "Accounting for Derivative Instruments and
           Hedging Activities." The statement requires the recognition of all
           derivatives as either assets or liabilities in the balance sheet and
           the measurement of those instruments at fair value. The accounting
           for changes in the fair value of a derivative depends on the planned
           use of the derivative and the resulting designation. Because the
           Company does not currently hold any derivative instruments and does
           not engage in hedging activities, the impact of the adoption of SFAS
           No. 133 did not have a material impact on financial position, results
           of operations or cash flows.

           Recent Accounting Pronouncements (Continued)

           In June 2001, the Financial Accounting Standards Board ("FASB")
           issued Statement of Financial Accounting Standards No. 141 ("SFAS
           141"), "Business Combinations". SFAS 141 requires the purchase method
           of accounting for business combinations initiated after June 30, 2001
           and eliminates the pooling-of-interests method. The Company does not
           believe that the adoption of SFAS 141 will have a significant impact
           on its financial statements.

           In June 2001, the FASB issued Statement of Financial Accounting
           Standards No. 142 ("SFAS 142"), "Goodwill and Other Intangible
           Assets", which is effective January 1, 2002. SFAS 142 requires, among
           other things, the discontinuance of goodwill amortization. In
           addition, the standard includes provisions for the reclassification
           of certain existing recognized intangibles as goodwill, reassessment
           of the useful lives of existing recognized intangibles,
           reclassification of certain intangibles out of previously reported
           goodwill and the identification of reporting units for purposes of
           assessing potential future impairments of goodwill. SFAS 142 also
           requires companies to complete a transitional goodwill impairment
           test six months from the date of adoption. The Company does not
           believe the adoption of SFAS 142 will have a significant impact on
           its financial statements.

3.         CONCENTRATIONS AND RISKS

           Financial instruments, which subject the Company to concentrations of
           credit risk, consist primarily of cash and cash equivalents and trade
           accounts receivable. The Company maintains its cash and cash
           equivalents with major financial institutions and, at times, such
           balances with any one financial institution may exceed FDIC insurance
           limits. The Company extends differing levels of credit to customers,
           does not require collateral deposits, and maintains reserves for
           potential credit losses based upon the expected collectibility of
           accounts receivable. The financial loss, should a customer be unable
           to meet its obligation to the Company, would be equal to the recorded
           accounts receivable. At both June 30, 2001 and December 31, 2000,
           four customers collectively represented 69% and 59% of total trade
           accounts receivable, respectively.

           The Company sells to customers primarily located in the United States
           of America.

           The Company currently purchases a number of key components of its
           product from a limited number of suppliers. Although there are a
           limited number of manufacturers of these components, management
           believes that other suppliers could provide such services on
           comparable terms.

           The Company is subject to a number of risks similar to other
           companies in the industry, including fluctuations in operating
           results affected by the changes in the economy, dependence on certain
           customers, and dependence on key individuals.

                 NOTES TO UNAUDITED PRO FORMA COMBINED CONDENSED
                              FINANCIAL STATEMENTS



                      To record the purchase accounting of the assets acquired
                      and the liabilities assumed. In consideration for the
                      acquisition of GPI, the Company issued 850,000 shares of
                      its common stock (based upon the average closing price for
                      two days before and the day of the consummation of the
                      transaction), subject to adjustment pending the completion
                      of a post-closing review of the purchased assets, and paid
                      cash of $177,000. Additionally, the Company accrued
                      $674,000 for transaction fees.



                      The Pro Forma Combined Condensed Balance Sheet has been
                      prepared based on the Company's unaudited consolidated
                      balance sheet and GPI's audited balance sheet as of
                      September 30, 2001.


                      A summary of the transaction is as follows (in thousands):




                                                                
                      Consideration:
                        Stock                                         $ 26,222
                        Cash paid                                          177

                                                                   ===========
                      Preliminary allocation of excess
                        purchase price over net tangible
                        assets acquired:
                        Identifiable intangible assets                $ 10,856
                        Goodwill                                        10,436
                                                                   -----------
                        Estimated excess of purchase price
                        over net tangible assets acquired             $ 21,292
                                                                   ===========

                      The preliminary allocation of $10,856,000 of identifiable
                      intangible assets include $9.7 million of completed
                      technology, $0.7 million of tradenames and trademarks, and
                      $0.5 million of non-competition agreements.





           (2)        To record amortization expense for the identifiable
                      intangible assets. The excess of the purchase price over
                      the fair value of the net tangible assets acquired has
                      been recorded based on a preliminary purchase price
                      allocation. Finalization of the allocation of the purchase
                      price to tangible and identifiable intangible assets
                      acquired and liabilities assumed is preliminary pending
                      collection of data to evaluate estimates of future
                      revenues and earnings to determine a discounted cash flow
                      valuation of certain intangibles that meet the separate
                      recognition criteria of FAS 141. Brooks expects this
                      process and subsequent allocation of purchase price to be
                      complete for inclusion in its Form 10-Q for the quarter
                      ended March 31, 2002. The Company anticipates that the
                      weighted average useful life of the acquired identifiable
                      intangible assets will be three years. The acquired
                      identifiable intangible assets will be amortized using the
                      straight-line method. A change in the allocation between
                      the acquired intangible assets and goodwill of $1,000,000
                      would result in a change in pro forma annual amortization
                      expense of approximately $333,000. An increase in the
                      weighted average useful life of the acquired identifiable
                      intangible assets from three to four years would result in
                      a decrease in pro forma annual amortization expense of
                      approximately $905,000 per year. A decrease in the
                      weighted average useful life of the acquired identifiable
                      intangible assets from three years to two years would
                      result in an increase in pro forma annual amortization
                      expense of approximately $1,809,000 per year. Goodwill has
                      not been amortized in accordance with the provisions of
                      FAS 142.



           (3)        To adjust the income tax expense recorded by GPI in its
                      historical statements of operations to reflect the 43.0%
                      tax rate applicable to a subsidiary of the Company
                      operating in California. This adjustment is $704,000 for
                      the year ended September 30, 2001.



           (4)        To record the income tax effect of the pro forma
                      adjustment to amortization of acquired intangible assets.
                      This adjustment was recorded at 43.0%, and results in
                      reductions of $1,556,000 to income tax expense for the
