NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS June 30, 2002

|1. | The unaudited financial information furnished herein, in the opinion of management, reflects all adjustments, consisting only of normal recurring adjustments, which are necessary
to state fairly the consolidated financial position, results of operations, and cash flows of GenStar Therapeutics Corporation as of and for the periods indicated. GenStar presumes that users of the interim financial information have read or have
access to the Companys audited consolidated financial statements and Managements Discussion and Analysis of Financial Condition and Results of Operations for the year ended December 31, 2001 and that the adequacy of additional disclosure
needed for a fair presentation, except in regard to material contingencies or recent significant events, may be determined in that context.  Accordingly, footnote and other disclosures which would substantially duplicate the disclosures

|2. | Cash and cash equivalents consist primarily of highly liquid investments with original maturities of 90 days or less when purchased.  Short-term investments consist of debt
and equity securities with maturities in excess of 90 days when purchased.  In accordance with the Financial Accounting Standards Boards Statement of Financial Accounting Standards (SFAS) No. 115, Accounting for Certain
Investments in Debt and Equity Securities, management determines the appropriate classification of short-term investment securities at the time of purchase and reevaluates such designation as of each balance sheet date.  Securities classified
as available-for-sale are carried at fair value, with gains and losses, if any, reported as a separate component of stockholders equity and included in comprehensive loss.

|3. | In accordance with the Financial Accounting Standards Boards SFAS No. 128, Earnings per Share,  net loss per share is based on the average number of shares of common
stock outstanding during the three and six-month periods ended June 30, 2002 and 2001.  Equivalent shares arising from convertible preferred stock, convertible debt, warrants for Common Stock and outstanding stock options have not been included
in the computation of net loss per share as their effect would be antidilutive.

|5. | In February 2001, the Company entered into a capital lease agreement under which up to $2,325,000 in equipment could be leased.  The Company financed $672,000 and $653,000
of equipment under this lease agreement during the six months ended June 30, 2002 and 2001, respectively, and has financed a total of $1,534,000 of equipment under this lease since inception.  Under the original terms of the lease, the lease
was to expire in February 2002, however the Company was granted an extension of the lease term through June 30, 2002.  No additional extension of the lease term was requested and the lease term expired June 30, 2002. Therefore, no additional
assets can be financed under this facility.

|6. | In April 2002, the Company entered into a research agreement with a corporate partner whereby the two companies will collaborate on certain research projects.  Under this
agreement GenStar will be reimbursed for expenses incurred during the 19 month term of the agreement, which are estimated to be $250,000.  An initial payment of $150,000 was due upon signing of the agreement and was recorded as deferred revenue
upon receipt.  In accordance with the provisions of the Securities and Exchange Commissions Staff Accounting Bulletin No. 101 (SAB 101), the revenue is recognized on a straight-line basis over the term of the agreement. 
A total of $24,000 was recognized as contract revenue during the six months ended June 30, 2002.

OVERVIEW

GenStar Therapeutics Corporation is a biotechnology company dedicated to the development of innovative gene therapy products utilizing advanced gene delivery technologies for the treatment of serious medical
disorders.  The primary focus of our research and development efforts is in the generation of products for the treatment of hemophilia, cancer and vaccines.

GenStar commenced operations as a
stand-alone entity in January 1996 and has been in the development stage since inception.  Our original mission was to develop products to treat diseases in urology, with a particular interest in prostate cancer. We had licensed technology that
uses the IL-3 gene to treat several types of cancer, but did not have technology to deliver the gene.  On July 8, 1998, we entered into an agreement with Baxter Healthcare Corporation in which we acquired the exclusive rights to certain gene
delivery technologies and laboratory equipment.  The gene delivery technology will be used to enhance our existing technology and to develop products to deliver other genes.  We believe that the gene delivery technology provides a higher
level of expression of the gene being delivered compared to other gene therapy approaches. Prior to our license of the technology, Baxter had been developing this technology for the treatment of hemophilia and cancer and had continued to fund the
development of our MAX-AD FVIII product for hemophilia through the date of treatment of the first patient in a clinical trial for that product.

In May 2000, we acquired all of the outstanding
shares of Allegro Cell Systems, Inc. (Allegro) in exchange for 288,000 shares of GenStar Common stock and an obligation to issue an additional 12,000 shares of common stock once approved by the University of California Regents.  Allegros
sole asset was a license to certain technologies for the treatment and prevention of AIDS and for lentiviral gene therapy.  Allegro has no products, revenues, employees, facilities or other assets.  Based upon the very early stage of
development of the technology and the lack of alternative future uses for it, the value of the technology was charged to acquired in-process technology.

GenStars current activities consist of
the development of the MAXIMUM-AD gene transfer system for our MAX-AD FVIII product, our DUAL-AD vector product for prostate cancer, and the MAX-AD and HIV vector systems for the treatment of HIV/AIDS.  We anticipate defining additional uses
for our vector technologies and potentially acquiring other technologies.  We expect to incur increasing research and development expenditures as we focus our efforts on further development of these products.  We expect that GenStar will
have no product revenues and will incur significant losses for at least the next five years.  We may never be profitable.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Our discussion and analysis of our financial
condition and results of operations are based upon the Companys consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial
statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates,
including those related to revenue recognition, patent costs and income taxes. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the
basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

We believe the following critical accounting policies affect the significant judgments and estimates used in the preparation of our consolidated financial statements.

Revenue recognition

We recognize revenue when all four of the following criteria are met:  (i) persuasive evidence that an arrangement
exists; (ii) delivery of services has occurred; (iii) the selling price is fixed or determinable; and (iv) collectibility is reasonably assured.  In addition, we follow the provisions of the Securities and Exchange Commissions Staff
Accounting Bulletin No. 101 (SAB 101), Revenue Recognition in Financial Statements, which sets forth guidelines in the timing of revenue recognition.  Amounts received for upfront product and technology license fees under
multiple-element arrangements are deferred and recognized over the period of such services or performance if such arrangements require ongoing services or performance.  Amounts received for milestones are recognized upon achievement of the
milestone, unless the amounts received are creditable against royalties or we have ongoing performance obligations.  Royalty revenue will be recognized upon sale of the related products, provided the royalty amounts are fixed and determinable
and collection of the related receivable is probable.  Grant revenue is recognized as the research expenses related to the grants are incurred. All amounts received under the collaborative research agreements or research grants are not
refundable, regardless of the success of the underlying research.  Any amounts received prior to satisfying our revenue recognition criteria will be recorded as deferred revenue in the accompanying balance sheets.

Patent costs

We expense the costs related to filing and pursuing patent applications as the costs are incurred because the recoverability
of such expenditures is uncertain.

Income taxes

We record a valuation allowance to reduce our deferred tax assets
to the amount that is more likely than not to be realized. While we have considered future taxable income and ongoing prudent and feasible tax planning strategies in assessing the need for the valuation allowance, in the event we were to determine
that we would be able to realize our deferred tax assets in the future in excess of its net recorded amount, an adjustment to the deferred tax asset would increase income in the period such determination was made. Likewise, should we determine that
we would not be able to realize all or part of our net deferred tax asset in the future, an adjustment to the deferred tax asset would be charged to income in the period such determination was made.  The Companys policy is record a
valuation allowance equal to the net deferred tax asset.

Stock based compensation

The Company grants stock options for a fixed number of shares to employees in accordance
with Accounting Principles Board Opinion No. 25 (APB 25), Accounting for Stock Issued to Employees, and accordingly, recognizes no compensation expense for the stock option grants to employees provided that the option exercise price is not
less than the fair market value of the underlying stock on the date of the grant.  The value of options, warrants, or stock awards issued to non-employees have been determined in accordance with SFAS No. 123, Accounting for Stock Based
Compensation, and Emerging Issues Task Force No. 96-18, Accounting for Equity Instruments that are Issued to Other than Employees for Acquiring, or in Conjunction with Selling Goods and Services, and are periodically remeasured as the
options vest.  Warrants for Common Stock are valued at the date of issuance and are recorded to the expense category related to the services provided.

Revenues

GenStar has generated revenues to date of $1,862,000 from contract research agreements and grants.   Total revenues for the six
months ended June 30, 2002 and 2001 were $440,000 and $72,000, respectively, and for the three months ended June 30, 2002 and 2001 were $172,000 and $40,000, respectively.  Revenues for both the three and six months ended June 30, 2002 include
$24,000 related to a research agreement with a corporate partner whereby the two companies will collaborate on certain research projects (see Note 6 to the Financial Statements).  There were no such research agreement revenues during the three
and six months ended June 30, 2001.  We anticipate seeking additional research agreements and grants to help fund research and development efforts.  We do not anticipate revenues from products for at least five years.

Research and development

Research and development expenses increased $460,000 to $4,735,000 during the six months ended June 30, 2002 compared to
$4,275,000 for the six months ended June 30, 2001.  During the three months ended June 30, 2002 research and development expenses increased $75,000 to $2,407,000 compared to $2,332,000 for the three months ended June 30, 2001.  Research
and development expenses increased in both the six month and three month periods ended June 30, 2002 compared to the same periods of 2001 due to an upgrade in the capacity of our manufacturing capabilities.  We anticipate increasing research
and development expenditures in the future as we conduct preclinical and clinical testing necessary to bring our products to market and to establish additional manufacturing capabilities.

General and administrative expense

General and administrative expense decreased $94,000 during the six months ended June 30, 2002 to $1,617,000 compared to $1,711,000 for
the six months ended June 30, 2001.  During the three months ended June 30, 2002 general and administrative expense decreased $72,000 to $808,000 compared to $880,000 for the three months ended June 30, 2001.  General and administrative
expenses include the costs of our administrative personnel and consultants, office lease expenses and other overhead costs, including legal and accounting costs. General and administrative expenses have decreased due to managements efforts to
reduce expenses in this area

Interest income and expense

Interest income decreased $163,000 during the six months ended June 30, 2002 to $446,000
compared to $609,000 for the six months ended June 30, 2001.  During the three months ended June 30, 2002 interest income decreased $64,000 to $248,000 compared to $312,000 for the three months ended June 30, 2001.  Interest income is a
result of the investment of excess cash in money market accounts, corporate bonds and certificates of deposit.  Interest expense decreased $22,000 for the six months ended June 30, 2002 to $231,000 compared to $253,000 for the six months ended
June 30, 2001.  During the three months ended June 30, 2002 interest expense decreased $16,000 to $114,000 compared to $130,000 for the three months ended June 30, 2001.  Interest expense in both 2001 and 2002 relates to equipment
financing and interest accrued on the deferred compensation liability.

LIQUIDITY AND CAPITAL RESOURCES

Net cash used by operating
activities during the six months ended June 30, 2001 and 2002 was $5,707,000 and $4,185,000, respectively. Net cash used by operating activities consists of expenditures for research and development and general and administrative expenses. Net cash
provided by investing activities during the six months ended June 30, 2001 and June 30, 2002 was $235,000 and $2,384,000, respectively, and consists of net sales of short-term investments further reduced by purchases of furniture and
equipment.  Net cash provided by financing activities during the six months ended June 30, 2001 of $4,766,000 consists primarily of $2,173,000 paid by Baxter under the credit agreement, proceeds from the sale of Series C Preferred Stock to
Baxter of  $2,000,000, proceeds from our capital lease facility of $653,000, offset by repayments of the capital lease facility and notes payable of $242,000. Net cash provided by financing activities of $61,000 for the six months ended June
30, 2002 consists primarily of proceeds from our capital lease facility of $429,000, offset by repayments of the capital lease facility and notes payable of $383,000.

GenStars future capital
requirements will depend on many factors, including scientific progress in our research and development programs, our ability to establish collaborative arrangements with others for drug development, progress with preclinical and clinical trials,
the time and costs involved in obtaining regulatory approvals and effective commercialization activities.  As of June 30, 2002, the Company had cash, cash equivalents and short-term investments totaling $10,403,000 and working capital of
$8,796,000.  GenStar has incurred net losses of $42.6 million since its inception through June 30, 2002 and has never been profitable during its existence. We expect to incur significant additional operating losses over the next several years
as our research and development efforts expand. Our ability to achieve profitability depends upon our ability, alone or with others, to successfully complete development of products, obtain required regulatory approvals and manufacture and market
products. We may not be successful and we may never attain significant revenues or profitability. Our operations to date have consumed substantial amounts of cash. The negative cash flow from operations is expected to continue and to accelerate for
at least the next five years. The development of our products will require a commitment of substantial funds to conduct the costly and time-consuming research, preclinical and clinical testing necessary to bring our products to market and to
establish manufacturing and marketing capabilities.

Under the terms of our Developmental Collaboration Agreement and Credit Agreements with Baxter, Baxter was required to provide funding for
development of the MAX-AD FVIII hemophilia product.  Total funding received from Baxter under the agreement was $12,890,000, which was converted into 12,890 Shares of Series B Preferred Stock.  When we treated the first patient in a Phase
I clinical trial for the hemophilia product, a milestone payment of $2,000,000 was due from Baxter. In June 2001, the first patient was treated using the hemophilia product and Baxter paid the $2,000,000 milestone payment in exchange for 2,000
shares of Series C Preferred Stock.  The Series B Preferred Stock is convertible into 2,010,920 shares of common stock.  The Series C Preferred Stock is convertible at Baxters option upon

the earlier of (i) the first business day following the approval by the FDA of the right to market, sell or distribute any product using the MAXIMUM-AD Vector Technology for
treatment of blood clotting disorders in humans relating to Hemophilia A, which product has been developed pursuant to the Developmental Collaboration Agreement between Baxter and the Company and (ii) the date seven years after the achievement of
the most recently achieved Series C Milestone, currently in June 2001.

We anticipate our existing capital resources will enable us to maintain our current and planned operations through the middle
of 2003.  However, no assurance can be given that we will not need additional funds prior to the middle of 2003.  We will need to raise substantial additional capital to fund future operations. We intend to seek additional funding either
through collaborative arrangements or through public or private equity or debt financings. Additional financing may not be available on acceptable terms or at all.  If adequate funds are not available, we may be required to delay or reduce the
scope of our operations or to obtain funds through arrangements with collaborative partners or others that may require us to relinquish rights we may otherwise have.

QUANTITATIVE AND QUALITATIVE
DISCLOSURES ABOUT MARKET RISK

The primary objective of our investment activities is to preserve principal while at the same time maximizing the income we receive from our investments without
significantly increasing risk. Some of the securities that we invest in may have market risk. This means that a change in prevailing interest rates may cause the fair value of the principal amount of the investment to fluctuate. For example, if we
hold a security that was issued with a fixed interest rate at the then-prevailing rate and the prevailing interest rate later rises, the fair value of the principal amount of our investment will probably decline. To minimize this risk, we maintain
our portfolio of cash equivalents and short-term investments in a variety of securities, including commercial paper, money market funds, government and non-government debt securities. The average duration of all of our investments has generally been
less than one year. Due to the short-term nature of these investments, we believe we have no material exposure to interest rate risk arising from our investments. Therefore, no quantitative tabular disclosure is required.

The Company does not conduct business with foreign entities, and does not have any foreign exchange risk.
