Note 1.    ORGANIZATION AND NATURE OF BUSINESS

      Goldstrike Inc. (the "Company") was incorporated on June 9, 2003 in the
      State of Nevada, to pursue opportunities in the field of mineral
      exploration. June 9, 2003 is also the inception date of the Company.

Going Concern

      These financial statements have been prepared in accordance with generally
      accepted accounting principles in the United States of America applicable
      to a going concern which assume that the Company will realize its assets
      and discharge its liabilities in the normal course of business. The
      Company has incurred losses since inception of $192,898 to September 30,
      2005 and has working capital of $8,176,568 as at September 30, 2005. These
      factors create doubt as to the ability of the Company to continue as a
      going concern. Realization values may be substantially different from the
      carrying values as shown in these financial statements should the Company
      be unable to continue as a going concern. Management is in the process of
      identifying sources for additional financing to fund the ongoing
      development of the Company's business. (See Note 8 Subsequent event)

Note 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of presentation

      These financial statements have been prepared in accordance with
      Accounting Principles Generally Accepted in the United States ("USGAAP").

Exploration stage company

      The Company is an exploration stage company as it does not have an
      established commercial deposit and is not in the production stage.

Use of estimates

      The preparation of financial statements in conformity with USGAAP 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 the reported
      amounts of revenues and expenses during the reporting periods. Actual
      results could differ from those estimates.

Note 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (cont'd)

Cash

      Cash consists of cash on deposit with the Company's bankers.

Income Taxes

      Provisions for income taxes are based on taxes payable or refundable for
      the current year and deferred taxes on temporary differences between the
      amount of taxable income and pretax financial income and between the tax
      bases of assets and liabilities and their reported amounts in the
      financial statements. Deferred tax assets and liabilities are included in
      the financial statement at currently enacted income tax rates applicable
      to the period in which the deferred tax assets and liabilities are
      expected to be realized or settled as prescribed in FASB Statement No.
      109, Accounting for Income Taxes. As changes in tax laws or rates are
      enacted, deferred tax assets and liabilities are adjusted through the
      provision for income taxes.

Compensated absences

      Employees of the Company are entitled to paid vacations, sick days and
      other time off depending on job classification, length of service and
      other factors. It is impractical to estimate the amount of compensation
      for future absences, and accordingly, no liability has been recorded in
      the accompanying financial statements. The Company's policy is to
      recognize the costs of compensated absences when paid to employees.

Net profit per share

      Goldstrike adopted Statement of Financial Accounting Standards No. 128
      ("FASB 128") that requires the reporting of both basic and diluted
      earnings per share. Basic earnings per share is computed by dividing net
      income available to common shareowners by the weighted average number of
      common shares outstanding for the period. Diluted earnings per share
      reflects the potential dilution that could occur if securities or other
      contacts to issue common stock were exercised or converted into common
      stock. In accordance with FASB 128, any anti-dilutive effects on net loss
      per share are excluded.

Note 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (cont'd)

Disclosure about fair value of financial instruments

      Goldstrike has financial instruments, none of which are held for trading
      purposes. Goldstrike estimates that the fair value of all financial
      instruments at September 30, 2005, as defined in FASB 107, does not differ
      materially from the aggregate carrying values of its financial instruments
      recorded in the accompanying balance sheet. The estimated fair value
      amounts have been determined by the Company using available market
      information and appropriate valuation methodologies. Considerable judgment
      is required in interpreting market data to develop the estimates of fair
      value, and accordingly, the estimates are not necessarily indicative of
      the amounts that the Company could realize in a current market exchange.

Concentration of credit risk

      Financial instruments that potentially subject Goldstrike to a significant
      concentration of credit risk consists primarily of cash which is not
      collateralized. Goldstrike limits its exposure to credit loss by placing
      its cash with high credit quality financial institutions.

      Other Comprehensive Income

      There is no other comprehensive income to September 30, 2005.

Foreign currency translation

      The accounts of Goldstrike are translated into US Dollars on the following
      basis:

      o     Monetary assets and liabilities are translated at the current rate
            of exchange.
      o     The weighted average exchange rate for the period is used to
            translate revenue, expenses, and gains or losses from the functional
            currency to the reporting currency.
      o     Gains or losses on re-measurement are recognized in current net
            income.
      o     Gains or losses from foreign currency transactions are recognized in
            current net income.
      o     Fixed assets are measured at historical exchange rates that existed
            at the time of the transaction.
      o     Depreciation is measured at historical exchange rates that existed
            at the time the underlying related asset was acquired.
      o     There are no cumulative currency translation adjustments to
            September 30, 2005.

Note 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (cont'd)

Stock-based Compensation

      In December 2002, the Financial Accounting Standards Board issued
      Financial Accounting Standard No. 148, "Accounting for Stock-Based
      Compensation - Transition and Disclosure" ("SFAS No. 148"), an amendment
      of Financial Accounting Standard No. 123 "Accounting for Stock-Based
      Compensation" ("SFAS No. 123"). The purpose of SFAS No. 148 is to: (1)
      provide alternative methods of transition for an entity that voluntarily
      changes to the fair value based method of accounting for stock-based
      employee compensation, (2) amend the disclosure provisions to require
      prominent disclosure about the effects on reported net income of an
      entity's accounting policy decisions with respect to stock-based employee
      compensation, and (3) to require disclosure of those effects in financial
      information.

      The Company has elected to continue to account for stock-based employee
      compensation arrangements in accordance with the provisions of Accounting
      Principles Board Opinion No. 25, "Accounting for Stock Issued to
      Employees", ("APB No. 25") and comply with the disclosure provisions of
      SFAS No. 123 as amended by SFAS No. 148 as described above. In addition,
      in accordance with SFAS No. 123 the Company applies the fair value method
      using the Black-Scholes option-pricing model in accounting for options
      granted to consultants. Under APB No. 25, compensation expense for
      employees is recognized based on the difference, if any, on the date of
      grant between the estimated fair value of the Company's stock and the
      amount an employee must pay to acquire the stock. Compensation expense is
      recognized immediately for past services and pro-rata for future services
      over the option-vesting period. To September 30, 2005 the Company has not
      granted any stock options.

      The Company accounts for equity instruments issued in exchange for the
      receipt of goods or services from other than employees in accordance with
      SFAS No. 123 and the conclusions reached by the Emerging Issues Task Force
      in Issue No. 96-18. Costs are measured at the estimated fair market value
      of the consideration received or the estimated fair value of the equity
      instruments issued, whichever is more reliably measurable. The value of
      equity instruments issued for consideration other than employee services
      is determined on the earliest of a performance commitment or completion of
      performance by the provider of goods or services as defined by EITF 96-18.


      The Company has also adopted the provisions of the Financial Accounting
      Standards Board Interpretation No.44, Accounting for Certain Transactions
      Involving Stock Compensation - An Interpretation of APB Opinion No. 25
      ("FIN 44"), which provides guidance as to certain applications of APB 25.


      No disclosures relating to stock based compensation have been included
      with the accompanying financial statements, as no stock options have been
      granted to directors and employees.

Note 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (cont'd)

General and Administration Expenses

      General and administration expenses are recorded on an accrual basis as
incurred.

Mineral property acquisition costs and deferred exploration expenditures

      a)    Mineral property acquisition costs are capitalized in accordance
            with FAS-141 subject, however to impairment pursuant to FAS-144.
            Exploration costs and mine development costs to be incurred,
            including those to be incurred in advance of commercial production
            and those incurred to expand capacity of proposed mines, are
            expensed as incurred while Goldstrike is in the exploration stage.
            Mine development costs to be incurred to maintain production will be
            expensed as incurred. Depletion and amortization expense related to
            capitalized mineral properties, exploration costs and mine
            development costs will be computed using the units-of-production
            method based on proved and probable reserves.

      b)    FAS-141 states that the total carrying amount of mineral rights
            should be reported as a separate component of property, plant, and
            equipment on the face of the financial statements or in the notes to
            the financial statements. Impairment is defined in FAS-144 as the
            condition that exists when the carrying amount of a long-lived asset
            exceeds its fair value. An impairment loss is recognized only if the
            carrying amount of a long-lived asset is not recoverable and exceeds
            its fair value. The Company reviews the carrying value of the
            mineral property for impairment whenever events and circumstances
            indicate that the carrying value of an asset may not be recoverable
            from the estimated future cash flows expected to result from its use
            and eventual disposition. In cases where undiscounted expected
            future cash flows are less than the carrying value, an impairment
            loss is recognized equal to an amount by which the carrying value
            exceeds the fair value of assets. The factors considered by
            management in performing this assessment include current operating
            results, trends, and prospects, as well as the effects of
            obsolescence, demand, competition, and other economic factors.

      c)    Where properties are disposed of, the sales proceeds are, firstly,
            applied as a recovery of mineral property acquisition costs, and
            secondly, as a gain or loss recorded in current operations.

Note 3. MINERAL PROPERTIES

      On June 30, 2003, Goldstrike signed a Mineral Property Sale Agreement with
      Joseph Eugene Leopold Lindinger ("Eugene"), whereby Goldstrike acquired a
      100% undivided interest in the BIZ Properties (BIZ1, BIZ2, BIZ6 and BIZ7
      (Tenure Number 366276, 369518, 369719 and 370056)), located in the
      Kamloops Mining Division, in the Province of British Columbia, Canada, and
      Goldstrike agreed to the following terms and conditions:

      a)    Pay to Eugene $3,584 and issue to Eugene 50,000 common shares
            (issued) at the price of $0.001 per share for $50 on execution of
            the agreement, for a total of $3,634.

      b)    Within the 120 day period after the effective date of June 30, 2003,
            pay $2,514 to Eugene to complete an assessable exploration work
            program of sufficient value in order to maintain the property for at
            lease one year past the current claim expiry date. Within 90 days of
            the current claim expiry date of November 1, 2003, pay an additional
            $2,286 for the remainder of the completed work program and a
            completed assessment report.

      c)    Pay all applicable claim maintenance recording fees as part of the
            property maintenance requirements.

      d)    Pay expenses related to this property, including the abovementioned
            expenses, total $8,754 from date of inception.

Note 4. INCOME TAXES

      There is a loss of $192,898 carried forward that may be applied towards
      future profits.

      The Company does not have any income tax liabilities during the current
      year and, accordingly, no income taxes are recorded. The potential income
      tax benefits associated with losses incurred by the Company have not been
      recorded in the accounts as future taxation as they are offset by
      valuation reserves due to uncertainty of utilization of tax losses.

      The income tax effect of temporary differences comprising the deferred tax
      assets and deferred tax liabilities on the accompanying consolidated
      balance sheets is a result of the following:

Note 7. RELATED PARTY TRANSACTIONS

      During the current quarter ended September 30, 2005, a loan of $35,040 was
      received from a related party who is a Director and Officer of the
      Company. This loan bears no interest, is unsecured, and has no specific
      terms of repayment.

Note 8 SHARE ISSUANCE

      During the period, the Company entered into discussions with Gran Tierra
      Energy, Inc ("Gran Tierra") regarding the possibility of a business
      combination involving the two companies (see Note 10). Gran Tierra is a
      private international oil and gas exploration and production company,
      incorporated in Alberta, Canada. To facilitate the discussions, the
      Company determined to provide financing to Gran Tierra to enable Gran
      Tierra to consummate certain property acquisitions in Argentina for a
      purchase price of approximately $7,000,000 (the "Argentine Acquisition").
      The Company derived the funds necessary to provide this financing from the
      proceeds of the initial closing of a private offering of its securities.

      As of September 30, 2005, a total of 10,422,395 units ("Units") were sold
      in connection with the private offering at the purchase price of $0.80 per
      Unit. The Units consisted of one share of the common stock of the Company
      and one warrant to purchase one-half of one share of common stock of the
      Company at an exercise price of $0.625 per one-half share. Proceeds from
      the offering totaled $8,337,916.

Note 8 SHARE ISSUANCE (Cont'd)

      On August 30, 2005, the Company's Board of Directors approved a stock
      dividend for the purpose of affecting a 3.91304347826 for 1 stock split of
      the issued shares of common stock of the Company, resulting in the
      issuance of 9,613,043 shares. The record date and payment date on the
      dividend was August 31, 2005.

Note 9 LOAN AND INTEREST RECEIVABLE

      The Company's financing of the Argentine Acquisition was evidenced by a
      loan agreement (the "Bridge Loan Agreement"), dated as of September 1,
      2005, pursuant to which the Company agreed to make loans to Gran Tierra in
      an amount up to the proceeds received in the private placement offering of
      Units (the "Loan Commitment"). At September 30, 2005, the amount of the
      Loan Commitment was $8,337,916. On the execution and delivery of the Loan
      Agreement, Gran Tierra borrowed $6,665,198.30 under the Bridge Loan
      Agreement. The note evidencing the loans made to Gran Tierra bears
      interest at a rate of 9% per annum on the amount of the Loan Commitment
      and is payable monthly. At September 30, 2005, this interest amount is
      accrued.

Note 10. SUBSEQUENT EVENTS

      With reference to Note 8, there was an additional closing of the private
      placement offering of Units on October 7, 2005 and an additional private
      offering of Units which closed on October 28, 2005, the proceeds of which
      were used to provide additional working capital to Gran Tierra.

      With reference to Note 9, effective as of the date of the additional
      closing of the private placement offering, the Loan Commitment was
      increased from $8,337,916 to $9,313,492, and Grand Tierra borrowed an
      additional $800,000 under the Bridge Loan Agreement. Effective as of the
      date of the additional closing of the private placement offering, the Loan
      Commitment was increased from $9,313,492 to $10,313,492, and Grand Tierra
      borrowed an additional $700,000 under the Bridge Loan Agreement.

      On November 10, 2005, pursuant to a share purchase agreement among the
      Company, Gran Tierra and holders of shares of capital stock in Gran
      Tierra, and an assignment agreement between the Company and Goldstrike
      Exchange Co. ("Exchangco"), a Canadian corporation indirectly-owned by the
      Company, the Company acquired 96.03% of the outstanding shares of capital
      stock in Gran Tierra in exchange for which, each Gran Tierra stockholder,
      at their election, received either 1.5873016 shares of common stock of
      Goldstrike or 1.5873016 shares of exchangeable stock of Goldstrike
      Exchange Co, and the Company changed its name to Gran Tierra Energy Inc.
      (the "Share Exchange"). Exchangeco intends to carry out a compulsory
      acquisition transaction in accordance with the Business Corporations Act
      to acquire the Gran Tierra shares not already acquired as the result of
      the share purchase. After completion of such transaction, Gran Tierra will
      become a indirectly-owned subsidiary of the Company.

Note 10. SUBSEQUENT EVENTS (Cont'd)

      In conjunction with the closing of the Share Exchange, 2,347,827 shares of
      common stock of the Company previously owned by Dr. Ken Cai were retired.

      Simultaneous with the consummation of the Share Exchange, the Company,
      Gran Tierra, Goldstrike Callco, a corporation incorporated under the laws
      of Alberta Canada ("Callco") and Olympia Trust Company, a Canadian
      corporation (the "Trustee") executed a voting exchange and support
      agreement to make provision for and establish a procedure whereby voting
      rights in the Company will be exercisable by the Trustee for the benefit
      of the holders of exchangeable shares. The Company issued to the Trustee,
      for the benefit of the beneficiaries, one share of special voting stock,
      at $.001 par value and Callco granted to the Trustee the right, under
      certain circumstances, to require Callco to purchase the exchangeable
      shares.

      Immediately prior to the Share Exchange, the Company transferred to
      Goldstrike Leasco Inc., a newly-formed Nevada corporation wholly owned by
      the Company ("Leaseco") all of the Company's rights and interests in the
      Mineral Property Sale Agreement previously entered into by the Company.
      The Mineral Property Sale Agreement was filed by the Company with the
      Securities and Exchange Commission on March 24, 2005.

      Simultaneous with the closing of the Share Exchange, upon the terms and
      conditions of a split-off agreement (the "Split-off Agreement") among the
      Company, Leasco, Dr. Yenyou Zheng (the "Split-off Purchaser") and Gran
      Tierra, the Company sold all the issued and outstanding shares of capital
      stock of Leasco to the Split-off Purchaser in exchange for all of the
      shares of common stock owned by the Split-off Purchaser and the assumption
      by the Split-off Purchaser of all responsibilities for any debts,
      obligations and liabilities of Leasco.

      In connection with the consummation of the Share Exchange, the address of
      our principal executive offices was changed to 10th Floor, 610-8th Avenue
      S.W., Calgary, Alberta, Canada T2P 1G5 and the telephone number of our
      executive offices was changed to (403) 537-3218.

      With reference to Note 8 and Note 9 and in connection with the
      consummation of the Share Exchange, the bridge loan and accrued interest
      amounts were forgiven.

Item 2: Plan of Operation

Forward Looking Statements

This Quarterly Report on Form 10-QSB contains forward-looking statements within
the meaning of Section 27A of the Securities Act of 1933, as amended, and
Section 21E of the Securities Exchange Act of 1934. This Quarterly Report
includes statements regarding our plans, goals, strategies, intent, beliefs or
current expectations. These statements are expressed in good faith and based
upon a reasonable basis when made, but there can be no assurance that these
expectations will be achieved or accomplished. These forward looking statements
can be identified by the use of terms and phrases such as "believe," "plan,"
"intend," "anticipate," "target," "estimate," "expect," and the like, and/or
future-tense or conditional constructions ("will," "may," "could," "should,"
etc.). Items contemplating or making assumptions about, actual or potential
future sales, market size, collaborations, and trends or operating results also
constitute such forward-looking statements.

Although forward-looking statements in this Quarterly Report reflect the good
faith judgment of management, forward-looking statements are inherently subject
to known and unknown risks, business, economic and other risks and uncertainties
that may cause actual results to be materially different from those discussed in
these forward-looking statements. Readers are urged not to place undue reliance
on these forward-looking statements, which speak only as of the date of this
Quarterly Report. We assume no obligation to update any forward-looking
statements in order to reflect any event or circumstance that may arise after
the date of this Quarterly Report, other than as may be required by applicable
law or regulation. Readers are urged to carefully review and consider the
various disclosures made by us in the our reports filed with the Securities and
Exchange Commission which attempt to advise interested parties of the risks and
factors that may affect our business, financial condition, results of operation
and cash flows. This discussion should be read in conjunction with the
consolidated financial statements including the related footnotes. If one or
more of these risks or uncertainties materialize, or if the underlying
assumptions prove incorrect, our actual results may vary materially from those
expected or projected.

We were incorporated in the State of Nevada on June 9, 2003 under the name
Goldstrike, Inc. to pursue opportunities in the field of mineral exploration. On
June 30, 2003, pursuant to a Mineral Property Sale Agreement, we acquired a 100%
undivided mineral interest in properties located in the Province of British
Columbia, Canada (the "Goldstrike Property").

In July 2005, we retained P & L Geological Services ("P&L") to conduct the first
phase of exploration on the Goldstrike Property. On its review and sampling, P&L
indicated that the Goldstrike Property did not host readily available areas of
significant mineralization for follow-up exploration. Based on P&L's report,
Goldstrike decided not to conduct any further exploration on these mineral
claims and began to review other potential resource and non-resource assets for
acquisition.

On November 10, 2005, pursuant to a share purchase agreement among the Company,
Gran Tierra Energy Inc., an Alberta corporation ("Gran Tierra Alberta") and
holders of shares of capital stock in Gran Tierra Alberta and an assignment
agreement between the Company and Goldstrike Exchange Co, a Canadian corporation
indirectly-owned by the Company ("Exchangeco"), Exchangeco acquired 96.03% of
the outstanding shares of capital stock in Gran Tierra Alberta ("Gran Tierra
Shares") in exchange for which each stockholder of Gran Tierra Alberta, at their
election, received either 1.5873016 shares of common stock of the Company
("Common Stock") or 1.5873016 shares of exchangeable stock of Exchangeco
("Exchangeable Shares"); and the Company changed its name from Goldstrike, Inc.
to Gran Tierra Energy Inc. (referred to hereinafter as the "Company" or "Gran
Tierra") (the "Share Purchase"). Exchangeco intends to carry out a compulsory
acquisition transaction in accordance with the Business Corporations Act
(Alberta) to acquire the Gran Tierra Shares not already acquired as the result
of the Share Purchase. After completion of such transaction, Gran Tierra Alberta
will become an indirectly-owned subsidiary of the Company.


                                       16


Gran Tierra Alberta is a private international oil and gas exploration and
production company, incorporated in Canada in January 2005 that commenced
business activity in May 2005 with capital obtained through its initial
financing of approximately $1.8 million. Gran Tierra Alberta was founded to
capitalize on the experience of its management team, to access exploration and
development opportunities and leverage strategic relationships to build a
diverse international oil and gas company, initially focusing on business
opportunities in South America with the intent to expand its activities in the
future into North Africa, the Middle East and Southeast Asia.

On September 1, 2005, Gran Tierra Alberta acquired certain interests in
producing and non-producing properties in Argentina consisting of a 14%
participation in several producing oil fields governed by a single joint
venture, and a 50% interest in two additional properties.

On August 31, 2005 the Company's president, C.E.O and a director, Dr. Ken Cai,
resigned from these positions. Dr. Jeff Yenyou Zheng was appointed president and
C.E.O. On September 1, 2005, Greg Yanke was appointed as a director. On November
2, 2005, Dr. Yenyou Zheng, resigned from his positions. On November 2, 2005, we
appointed Greg Yanke as our president, chief executive officer, secretary and
treasurer. The current members of the Board of Directors and management team
assumed their positions concurrent with the Share Purchase consummated on
November 10, 2005.

Capital expenditures for the Palmar Largo joint venture, the most significant
property acquired in Argentina, have been unusually high in 2005 due principally
to the drilling of two wells, contributing to a capital budget of approximately
$20.8 million for the year ($2.9 million for a 14% share). Gran Tierra's share
of expenditures to December 31, 2005 is expected to be approximately $2.2
million and is being funded partly from cash flow and partly from available
cash. Following the completion of the second well expected in December 2005,
cash flow surpluses are expected to return. Plans for the Palmar Largo joint
venture for 2006 include a modest expenditure budget, with no additional
drilling. The preliminary capital budget for 2006 is $1.2 million to Gran
Tierra.

Gran Tierra Alberta completed its initial equity financing to acquire funds for
general and administrative expenses incurred as it assessed opportunities and
identified an appropriate first acquisition. We completed a private placement
offering via Goldstrike, the proceeds of which were used to fund the Argentine
acquisition and provide additional working capital. Operating cash flow
generated by the Argentina properties will allow Gran Tierra to expand its
activities and capabilities by hiring additional staff.

We plan on continuing to assess opportunities and identify appropriate
acquisitions. Current acquisition targets include "tuck-in" opportunities in
Argentina as well as acquisitions which will provide us with new country
entries. Identification and successful completion of such acquisitions will
provide additional cash flow which will allow us to expand our activities and
capabilities, assume a role as an operator and advance exploration and
development opportunities.

We expect an increase in general and administrative expenditures to
approximately $200,000 per month, equivalent to expected operating cash flow. We
have expanded our staff in Calgary from three to six employees with additions in
the areas of geoscience, accounting and administration, and are targeting one or
two additional hires. We are establishing an office in Buenos Aires, Argentina
and our Vice President of Latin America is re-locating from Quito, Ecuador. Our
staff complement in Buenos Aires is expected to increase to three before
year-end, with an operational focus. We are targeting two additional hires in
Buenos Aires early in 2006.


                                       17


We expect our net cash position to stabilize in January 2006 (following the
drilling of the Palmar Largo well). A portion of Gran Tierra's current cash
balance will cover the projected cash deficit to that time.

OFF-BALANCE SHEET ARRANGEMENTS

We do not have any off-balance sheet arrangements.

Item 3.  Controls and Procedures

(a)   Evaluation of Disclosure Controls and Procedures

      The term "disclosure controls and procedures" is defined in Rules
      13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended
      (the "Exchange Act"). This term refers to the controls and procedures of a
      company that are designed to ensure that information required to be
      disclosed by a company in the reports that it files under the Exchange Act
      is recorded, processed, summarized, and reported within the required time
      periods.

      Our former chief executive officer and principal accounting officer, Dr.
      Yenyou Zheng, has evaluated the effectiveness of our disclosure controls
      and procedures as of the end of the period covered by this report.

      Based upon his evaluation of our controls, Dr. Yenyou Zheng has concluded
      that, as of that date, our disclosure controls and procedures were
      effective at ensuring that required information will be disclosed on a
      timely basis in our reports filed under the Exchange Act.

(b)   Changes in Internal Control over Financial Reporting

      No change in our internal control over financial reporting (as defined in
      Rules 13a-15(f) and 15d-15(f) under the Exchange Act) occurred during the
      period covered by this report that has materially affected, or is
      reasonably likely to materially affect, our internal control over
      financial reporting.
