NOTES TO CONDENSED FINANCIAL STATEMENTS

June 30, 2002

(Unaudited)



Note 1: Basis of Presentation



The accompanying unaudited condensed financial
statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not
include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a
fair presentation have been included. Operating results for the three and six-month periods ending June 30, 2002 are not necessarily indicative of the results that may be expected for the year ended December 31, 2002. For further information, refer
to the financial statements and footnotes thereto included in our annual report on Form 10-K for the year ended December 31, 2001.



Restatement of Financial Information



The balance sheets as of June 30, 2002 and December 31, 2001 have been restated to present our Series A Preferred Stock and related
accreted preferred stock dividends outside of permanent stockholders equity, as a result of the adoption of Emerging Issues Task Force (EITF) Topic No. D-98, Classification of and Measurement of Redeemable Securities. The Company issued the
Series A Preferred Stock in January 2000 in connection with the formation of its joint venture, Medizyme Pharmaceuticals, Ltd. (Medizyme), with Elan Corporation, plc. Shares of the Series A Preferred Stock are exchangeable for a portion of the
Companys investment in Medizyme. The effect of this restatement is to reduce total stockholders equity for the periods presented and to reflect the Series A Preferred Stock and related accreted stock dividends outside of permanent
equity. The right of Elan to exchange the Series A Preferred Stock is applicable for the period October 2002 through May 2003. If the exchange feature expires unexercised, the Series A Preferred Stock and accreted dividends will be reclassified to
permanent equity.



Note 2: Medizyme



In January 2000, the Company formed a joint venture with Elan
Corporation (Elan) for the development and commercialization of HERZYME, the Companys product to treat
breast and other cancers. As part of this arrangement, the Company licensed HERZYME and Elan licensed its MEDIPAD®drug delivery technology to the joint venture, Medizyme Pharmaceuticals, Ltd. (Medizyme). The MEDIPAD®system is a disposable continuous subcutaneous drug delivery system that allows a patient to administer the drug at home. We filed an IND for HERZYME in Canada in February 2001, which was approved in April 2001.



Initial funding of Medizyme included $12.0 million from the
Company and $3.0 million from Elan. Estimated funding for Medizyme will require approximately $15.0 million in additional operating and development costs and, therefore, Elan provided the Company with a $12.0 million credit facility on a draw-down
basis for the Company to use to fund the Companys portion of Medizyme operating costs over a 42-month period. The credit facility has a 12% interest rate and the outstanding balance, including interest, as of the end of May 2002 of $9.9
million was converted into 9,905 shares of the Companys

Series B Convertible Preferred Stock in June 2002. The Series B Preferred Stock has a nominal value of $1,000 per share, will accrue
dividends at an annual rate of 12%, and is ultimately convertible into the Companys common stock at a 50% premium to the average price of the common stock for the 60 trading days prior to the time of the applicable draw down on the credit
facility.



While the Company owns 80.1% of the
outstanding stock of Medizyme, Elan and its subsidiaries have retained significant minority investor rights that are considered participating rights, therefore the Company accounts for its investment in Medizyme under the equity method
of accounting. During the three and six-month periods ended June 30, 2002, the Company recognized $425,000 and $851,000, respectively, in contract revenues for research and development activities performed for Medizyme. These amounts are included in
the Companys revenues as Collaborative agreements-joint venture for the three and six-month periods ended June 30, 2002.



The unaudited results of operations of Medizyme for the six-month period ended June 30, 2002 are as follows (in thousands):

Overview of our Business



Ribozyme Pharmaceuticals, Inc. (RPI) is a leader in the field of nucleic acid technology. We are using our proprietary technology and our expertise in molecular engineering to develop a new class of
therapeutics, to develop diagnostic technologies that identify diseases, and to manufacture oligonucleotides (chains of nucleotides that can be chemically synthesized in specific sequences) for our use or for use by our collaborators and customers
to generate revenue.



Since inception in 1992, we
have dedicated ourselves to engineering RNA-based molecules using Nobel Prize-winning ribozyme technology. As a result, we have advanced product candidates into clinical development, developed RNA-based diagnostic technology, established leading
oligonucleotide manufacturing expertise and entered into several collaborative relationships with biotechnology and other companies. We own or have exclusive licenses to use over 182 issued or allowed patents relating to nucleic acid technology.
Having developed this unique expertise in nucleic acid technology and molecular engineering enables us to take our next step. We will sharpen our focus on those product candidates that we believe have the best prospects for commercial success and we
will use our expertise to design, stabilize, manufacture and deliver next generation ribozymes and RNA interference, or RNAi. We believe RNA-based drugs will become important therapeutics in the future. We are exceptionally well positioned to take
advantage of this emerging opportunity.



We are
developing a new class of therapeutics based on engineered RNA that are designed to disrupt intracellular production and replication of disease-inducing proteins and viruses. Our expertise in nucleic acid technology, which has been developed over a
ten-year period and is backed by broad patent protection, is focused on ribozymes and RNA interference, or RNAi. A ribozyme is a chain of nucleotides that has binding sequences along with a catalytic core capable of cleaving a specific RNA molecule,
including mRNA and viral RNA. mRNA and viral RNA are essential to the synthesis of proteins or viral replication responsible for disease. Ribozymes act as molecular scissors by cutting

##### Table of Contents

RNA molecules into two ineffective strands, thereby preventing undesirable protein production or viral replication. RNAi technology involves
using a double-stranded sequence of RNA capable of reducing the expression of mRNA and viral RNA in a sequence-specific manner. For simplicity, we refer to the double-stranded RNA molecule facilitating this process as RNAi. RNAi induces the
destruction of target RNA using a cells own protein machinery. We expect our RNA technologies to be applicable in a broad range of therapies, because many diseases result from undesirable protein production or viral replication.



RNA-based therapeutics have potentially significant advantages
over traditional approaches to treating diseases, including broad therapeutic application, therapeutic precision and target RNA destruction.



We are developing drugs that address significant and unmet medical needs. We are in clinical development for the following three product
candidates:



| |  |  | ANGIOZYME, which we are developing in collaboration with Chiron Corporation, to treat solid tumor cancers. We plan to continue our ANGIOZYME clinical program in
patients with metastatic colorectal cancer and will complete our preliminary analysis of 12-week data in the fourth quarter of 2002 and our preliminary analysis of 24-week data in the first quarter of 2003.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | HEPTAZYME, which we are developing to treat chronic hepatitis C. We have stopped our Phase II trial and pursuing a next generation ribozyme to treat hepatitis C
that we believe will prove to be more efficacious then our first-generation drug.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | HERZYME, which we are developing in collaboration with Elan Corporation plc and its affiliates, to treat breast and other solid tumor cancers. We expect to complete
Phase I clinical trials by year-end.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



We will use the preclinical data acquired in connection with another product candidate, HepBzyme, for the treatment of hepatitis B, to advance our continuing work with HEPTAZYME. We do not intend to pursue independent development of
HepBzyme.



Our business strategy is to use our
patented technology and molecular engineering expertise to create value by: (1) selectively developing RNA-based drugs; (2) building on our expertise in nucleic acid technology to develop next generation ribozymes and RNAi therapeutics through
collaborations with others; (3) developing diagnostics that our collaborators can use to identify diseases; (4) leveraging our nucleic acid expertise through licensing, process development and pilot manufacturing; and, (5) maintaining and expanding
our patent portfolio and proprietary technology.



Critical
Accounting Policies



Revenue
Recognition. To date, we have committed substantially all our resources to our research and product development programs. We have not generated any revenues from therapeutic product sales, nor do we anticipate generating any therapeutic product
revenues in the foreseeable future. Revenue recorded from our collaborative agreements consists of:



| |  |  | Up-front revenue. Up-front non-refundable fees are recognized upon signing an agreement when it represents an exchange for products delivered or for services
performed that represent the culmination of a separate earnings process. All other up-front fees are deferred and recognized
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



10



---

##### Table of Contents

systematically over the period the fees are earned. Up-front revenue also may include a reimbursement to us of recent expenses related to
product development which we incurred.



| |  |  | Research revenue. Typically, research revenue is based on the fully burdened cost of a researcher working on a collaboration. Rates are billed per employee, per
year, pro-rated for time worked on a project. This revenue is typically invoiced on a monthly basis, either up front or in arrears. Revenue is recognized ratably over the period, with the balance reflected as deferred revenue until earned. The
revenue is typically recurring over the term of a collaboration.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | License revenue. License revenue is recognized ratably over the term of the license. Payments received in advance are recorded as deferred revenue until earned.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Milestone revenue. Milestone revenue is recognized in full when the related milestone performance goal is achieved. Milestone revenue is typically not consistent or
recurring in nature.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



Our revenue
has consisted primarily of research revenue payments from our collaborators. All revenues are either deferred as a liability or recognized upon satisfying revenue criteria. As of June 30, 2002, all revenues that have been recognized are earned, and
no further obligation exists for recognized revenue. We depend upon funding from external financing and corporate collaborations for our research and product development programs and expect to depend upon this funding for the foreseeable future.



We have not been profitable since inception and
have an accumulated deficit of $177.4 million as of June 30, 2002. Losses have resulted primarily from expenses associated with our research and development programs. We expect to incur additional losses as ANGIOZYME, HEPTAZYME and HERZYME and other
potential product candidates advance through development and commercialization. In addition, future milestone payments under some of our collaborations are contingent upon our meeting particular research or development goals. The amount and timing
of future milestone payments are contingent upon the terms of each collaboration agreement. In some instances, we may forfeit milestone payments if we fail to accomplish a predetermined goal within a certain time frame. Therefore, we are subject to
significant variation in the timing and amount of our revenues and results of operations from period to period.



Our revenues are denominated in U.S. dollars. Therefore, we have not been exposed to foreign currency translation risks and have not
engaged in any hedging.



Deferred Patent
Costs. We capitalize legal costs directly incurred in pursuing patent applications as deferred patent costs. When such applications result in an issued patent, the related costs are amortized over the remaining legal life of the patents, which
is assumed to be 17 years, using the straight-line method. On a quarterly basis, we review our issued patents and pending patent applications and if we determine to abandon a patent application, or an issued patent no longer has economic value, the
unamortized balance in deferred patent costs relating to that patent is immediately expensed.



It is possible the estimates of future economic life of our commercialization revenues, the amount of anticipated future commercialization revenues, or both, will be reduced significantly in the near
term due to alternative technologies developed by other biotechnology or pharmaceutical companies. As a result, the carrying amount of deferred patent costs may be reduced in the future.



Equity in loss of unconsolidated affiliates. In January 2000, we formed a joint venture with Elan for
the development and commercialization of HERZYME. As part of the joint venture, we licensed HERZYME and Elan licensed its MEDIPAD®drug delivery technology to the joint venture, Medizyme Pharmaceuticals, Ltd. While we own 80.1% of the outstanding common stock of Medizyme, Elan has retained significant minority investor rights that are considered
participating rights as defined in EITF

##### Table of Contents

96-16 Investors Accounting for an Investee When the Investor Owns a Majority of the Voting Stock but the Minority Shareholder or
Shareholders Have Certain Approval or Veto Rights. Therefore, we do not consolidate the operations of Medizyme, but instead account for our investment in Medizyme under the equity method.



In 1998, we invested $2.0 million and transferred our gene
identification and target validation technology to atugen AG, a German privately-owned biotechnology company. Upon formation in 1998, we owned a majority of common stock outstanding in atugen; however, similar to the above discussion on
participating rights, minority investors of atugen retained significant investor rights and therefore we did not consolidate operations but instead accounted for our investment in atugen under the equity method. In 1999, we completely
expensed our investment in atugen. We currently own 31.6% of atugen and will record our share of any future profits.



Restatement of Financial Information



The balance sheets as of June 30, 2002 and December 31, 2001 have been restated to present our Series A Preferred Stock and related
accreted preferred stock dividends outside of permanent stockholders equity, as a result of the adoption of Emerging Issues Task Force (EITF) Topic No. D-98, Classification of and Measurement of Redeemable Securities. The Company issued the
Series A Preferred Stock in January 2000 in connection with the formation of its joint venture, Medizyme Pharmaceuticals, Ltd. (Medizyme), with Elan Corporation, plc. Shares of the Series A Preferred Stock are exchangeable for a portion of the
Companys investment in Medizyme. The effect of this restatement is to reduce total stockholders equity for the periods presented and to reflect the Series A Preferred Stock and related accreted stock dividends outside of permanent
equity. The right of Elan to exchange the Series A Preferred Stock is applicable for the period October 2002 through May 2003. If the exchange feature expires unexercised, the Series A Preferred Stock and accreted dividends will be reclassified to
permanent equity.



Results of Operations



Three and Six Months Ended June 30, 2002 and 2001



Revenues. Generally, revenue fluctuations result from
changes in the number of funded research projects as well as the timing and completion of contract milestones. Our revenues are split into three categories: (i) collaborative agreements, (ii) collaborative agreements-joint venture, and (iii)
collaborative agreements-related parties. Collaborative agreement revenues primarily includes revenues recorded from our arrangements with Chiron, Fujirebio and Geron. Chiron revenues are related to our collaboration on ANGIOZYME. Collaborative
agreements-joint venture includes revenues from Medizyme, our joint venture with Elan. Collaborative agreements-related parties, includes revenues recorded from atugen.



Collectively, collaborative revenues decreased to $1.6 million and $3.2 million for the three and six months
ended June 30, 2002, respectively, from $2.4 million and $4.5 million for the corresponding periods in 2001. The decrease is due primarily to lower research revenues associated with Medizyme, our joint venture on the development of HERZYME with
Elan, and with ANGIOZYME, our collaboration with Chiron. As HERZYME and ANGIOZYME move forward in clinical trials, less time is required of our researchers and more third-party expenses are incurred. Reimbursements from our collaborators for third
party expenses are credited against expenses and not recognized as revenue. Medizyme revenues were $425,000 and $851,000 for the three and six months ended June 30, 2002, compared to $1.1 million

##### Table of Contents

and $2.4 million, respectively, for the same periods in 2001. In addition, Chiron revenues decreased to $694,000 for the three-month period
ended June 30, 2002 compared to $807,000 for the corresponding period in 2001. Also, revenues recorded for atugen decreased to $157,000 and $384,000 for the three and six-month periods ended June 30, 2002, respectively, compared to $270,000 and
$548,000 for the corresponding periods in 2002 due to a reduction in services provided. However, while our joint venture and related parties revenue decreased for the reporting period, our revenue from other sources increased for the same period.
During the first quarter, we signed an agreement with Fujirebio, a Japanese diagnostic company, for the use of allosteric ribozymes that resulted in revenues of $222,000 and $296,000 for the three and six month period ended June 30, 2002,
respectively. In addition, for the quarter and six months ending June 30, 2002, we recognized $113,000 and $225,000 in revenues, respectively, from Geron for our consultation in the process development of the manufacturing technology of one of their
drugs. Generally, revenue fluctuations result from changes in the number of funded research projects as well as the timing and completion of contract milestones. However, we do expect that our research revenues may continue to decrease while
revenues related to our diagnostic collaborations and our nucleic acid technology expertise may increase.



Expenses.Research and development expenses decreased to $7.9 million and $14.6 million for the three and six months ended June 30,
2002, compared to $10.0 million and $21.1 million for the corresponding periods in 2001. The decrease of $2.1 million for the three-month period ending June 30, 2002 compared to the same period in 2001, was primarily due to $3.2 million of expenses,
net of partner reimbursements, we incurred during the second quarter of 2001 for third-party manufacturing costs for ANGIOZYME and HEPTAZYME to support our clinical trials, compared to $1.7 million we incurred during the second quarter in 2002. The
decrease of $6.5 million for the six-month period ending June 30, 2002 compared to the same period in 2001, was primarily due to $7.8 million incurred in third-party manufacturing expenses, net of partner reimbursements, during the first half of
2001, compared to $1.8 million we incurred for the six-month period ended June 30, 2002. We expect research and development expenses, including pre-clinical studies, clinical trials and manufacturing expenses, to continue to increase as we expand
our development programs for ANGIOZYME, HEPTAZYME and HERZYME.



General and administrative expenses increased to $1.3 million and $2.8 million for the three and six-months ended June 30, 2002, respectively, compared to $1.1 million and $2.1 million for the corresponding periods in 2001. The
increase in 2002 is the result of increased expenses necessary to manage and support our expanding product and business development efforts. We expect general and administrative expenses to continue to increase as a result of increasing legal and
other professional fees in connection with the overall scale-up of our operations, business development efforts and patent protection.



Interest income.Interest income decreased to $112,000 and $266,000 for the three and six months ended June 30, 2002 compared to
$596,000 and $1.5 million for the corresponding periods in 2001. The decrease is due to lower average balances in our cash, cash equivalents and securities available-for-sale as compared to the same periods in 2001. Cash balance at the end of the
second quarter of 2001 was $51.4 million compared to a cash balance of $21.9 million at June 30, 2002. Interest income generally fluctuates as a result of the average amount of cash available for investment and prevailing interest rates.



Interest expense.Interest expense
increased to $266,000 and $603,000 for the three and six month periods ending June 30, 2002, compared to $189,000 and $295,000, respectively, for the corresponding periods in 2001. The increase is due to additional borrowings to fund capital
equipment purchases and additional draw downs on our line of credit with Elan to fund our portion of Medizyme

expenses. Interest expense is expected to continue to increase in the future as we arrange for additional financing for operations.



Equity in loss of unconsolidated affiliate.Equity in loss of unconsolidated affiliate was $1.6 million and $3.0 million for the three and six-month periods ending June 30, 2002, respectively, compared to $2.1 million and $4.7 million for the corresponding periods in 2001. The expense is
our 80.1% share of Medizymes losses for the corresponding periods. While we own 80.1% of the outstanding common stock of Medizyme, Elan has retained significant minority investor rights that are considered participating rights as
defined in EITF 96-16 Investors Accounting for an Investee When the Investor Owns a Majority of the Voting Stock but the Minority Shareholder or Shareholders Have Certain Approval or Veto Rights. Therefore, we do not consolidate the
operations of Medizyme, but instead account for our investment in Medizyme under the equity method. The decrease in the losses recognized for the quarter and year to date period ended June 30, 2002 are due to the decreases in Medizymes
expenses related to the development of HERZYME. The decrease is the result of the transition of HERZYME from research to clinical trials. Medizymes 2002 year to date expenses include $2.5 million amortized expense for payment of a $15.0
million license fee paid to Elan in January 2000, as well as $1.0 million we invoiced Medizyme as of June 30, 2002 for research we conducted and clinical trial expenses we incurred with HERZYME.



Liquidity and Capital Resources



Since our inception, we have financed our operations through
sales of equity securities in public offerings, private placements of preferred and common stock, funds received under our collaborative agreements and financing under equipment and tenant improvement loans. From inception through June 30, 2002, we
have received approximately:



| |  |  | $29.0 million in net proceeds from private placements;
| | - |  | ------------------------------------------------------



| |  |  | $97.6 million in net proceeds from public offerings;
| | - |  | ----------------------------------------------------



| |  |  | $127.0 million from our collaborations; and
| | - |  | -------------------------------------------



| |  |  | $11.5 million from equipment financing.
| | - |  | ---------------------------------------



We had cash, cash equivalents and securities available-for-sale of $21.9 million at June 30, 2002 compared with $35.0 million at December
31, 2001. The $13.1 million decrease in cash, cash equivalents and securities available-for-sale is primarily the result of $12.4 million used for operations, net of revenues of $3.2 million; $3.0 million used for investments in equipment, leasehold
improvements, patents and additional investment in an unconsolidated affiliate; net $130,000 in loans to executives; $116,000 received in proceeds from equity transactions; $2.3 million received in proceeds from credit facilities; and $81,000 paid
for debt obligations.



We invest our cash, cash
equivalents and securities available-for-sale in interest-bearing, investment-grade securities.



Accounts receivable at June 30, 2002 were $1.3 million compared to $1.5 million at December 31, 2001. Accounts receivable at June 30, 2002 included $211,000 due from atugen for administrative services
and patent expenses, $310,000 due from Medizyme for research support for HERZYME and $618,000 due from Chiron for reimbursement of ANGIOZYME expenses, as well as $161,000 due from miscellaneous other sources.

Total
additions for property, plant and equipment for the six months ended June 30, 2002 were $1.3 million. As of June 30, 2002, $2.2 million was available for funding our equipment purchases with a loan facility through a credit institution. The loan
facility through the credit institution is available for draw downs through November 2002, currently averages an interest rate of 9.5%, and matures in 36 or 48 months depending on the type of equipment collateralized. We anticipate future property,
plant and equipment needs to be financed through the existing loan facility and additional credit facilities yet to be determined.



As of June 30, 2002, we have a commitment to purchase, before the end of December 2002, $3.8 million of drug from our manufacturing
partner.



In July 1994, we entered into an
agreement with Chiron to collaborate exclusively on up to five specific targets selected by Chiron. ANGIOZYME is being developed in collaboration with Chiron and we share equally all development costs and future profits with Chiron. In March 2001,
we issued 38,920 shares of our common stock to Chiron in exchange for reacquiring all rights to develop any product containing or utilizing an HIV target. We recorded an expense of $275,000 in March 2001 in connection with the issuance of the stock.
For the period ended June 30, 2002 we recorded $1.4 million and $273,000 in revenues and reimbursement of expenses, respectively, from Chiron for costs incurred for the clinical development of ANGIOZYME.



In April 1997, we entered into a purchase agreement,
subsequently amended, with Schering AG and Schering Berlin Venture Corporation, or SBVC, an affiliate of Schering AG as part of our target discovery and validation program. SBVC made a $2.5 million equity investment in us in April 1997 in exchange
for 212,766 shares of our common stock and made an additional equity investment of $2.5 million for 465,117 shares of our common stock in April 1998. Separately, Schering AG provided loans of $2.0 million in each of 1997, 1998, 1999, 2000 and 2001.
We received our final draw-down of $1.0 million from Schering AG in April 2001. The loans, which carry an interest rate of 8.0% per annum, are immediately convertible into equity at the option of Schering AG. Additionally, 50.0% of any borrowings we
make on the line of credit must be collateralized by equipment purchases. In April 2000, after the completion of our public offering, we repaid $6.9 million of our outstanding borrowings to Schering AG. In June 2000, Schering AG converted $997,000
of the loan balance into 42,435 shares of our common stock at a conversion price of $23.50. At June 30, 2002, we had $3.3 million in outstanding loans and accrued interest from Schering AG, which was convertible into approximately 2.4 million shares
of our common stock. Principal and interest payments are deferred until maturity of the loans in April 2004. As a result of the atugen formation in 1998, we now subcontract all of our existing target discovery and validation programs to atugen,
which does not affect the terms of our loan agreement with Schering AG.



In January 2000, we completed a joint venture with Elan for the development and commercialization of HERZYME, our potential product to treat breast and other cancers. In accordance with the collaboration, we sold to Elan our
Series A Convertible Exchangeable Preferred Stock for $12.0 million and, in turn, used those funds for initial funding of Medizyme. As of June 30, 2002 the Series A preferred stock and accrued stock dividends were convertible into approximately 1.2
million shares of our common stock. Also, as part of the collaboration, Elan purchased 641,026 shares of our common stock for a purchase price of $5.0 million. In addition, Elan purchased 500,500 shares of common stock for $5.0 million in May 2001,
which was at a premium to the market price. We have estimated that the development of HERZYME will require additional funds of up to $15 million and, therefore, Elan made available to us a $12.0 million credit facility to fund our portion of
Medizyme operating costs over a 42-month period. At the end of June 2002, we had utilized the credit facility and had borrowed $9.3 million. The note carried an interest rate of 12% compounded on a semi-annual basis. Elan converted this debt and
accrued interest into shares of our Series B Convertible Preferred Stock in June 2002. At June 30,

##### Table of Contents

2002, the Series B Convertible Preferred Stock, which will accrue dividends at a annual rate of 12%, is convertible into approximately
979,000 shares of our common stock. In aggregate, at June 30, 2002, all of our outstanding preferred stock with Elan is convertible into 2.1 million shares of our common stock. In addition, Elan purchased 750,000 shares of our common stock and a
five-year warrant to purchase 75,000 shares of our common stock at $5.00 per share in December 2001 for $3.0 million.



In mid-2002, Elan announced that it would limit the focus of its clinical programs. Elans announced clinical programs do not include
cancer programs. We have not received any notice from Elan concerning our collaboration arrangement; however, based solely on Elans public statements, we believe that, following completion of our Phase I study later this year, it is unlikely
that Elan will continue to support HERZYME development. We do not intend to pursue development of HERZYME without a new corporate partner. Our ability to attract a new corporate partner will depend principally on the success of our Phase I study.



In connection with announcing our results of the
quarter ended June 30, 2002, we announced that we are realigning our research and development programs to focus our internal development on only those programs we believe have a high likelihood of commercial success. We will be discontinuing our
current HEPTAZYME program and beginning work on a next generation ribozyme therapeutic for hepatitis C. In addition, we will be leveraging our nucleic acid expertise to develop next generation ribozyme and RNAi based therapeutics, developing
diagnostic technologies for use by our collaborators and entering into licensing, process development and manufacturing arrangements. As a result, we will reorganize certain departments and reduce staff. We expect that this will reduce operating
expenses by approximately 35% in 2003.



We
anticipate that our existing financial resources and expected revenues from collaborations, should be sufficient to meet our anticipated operating and capital requirements through 2002. We expect to incur substantial additional costs, including,
costs related to:



| |  |  | our research, drug discovery and development programs;
| | - |  | ------------------------------------------------------



| |  |  | preclinical studies and clinical trials of our products, if developed;
| | - |  | ----------------------------------------------------------------------



| |  |  | prosecuting and enforcing patent claims;
| | - |  | ----------------------------------------



| |  |  | general administrative and legal items; and
| | - |  | -------------------------------------------



| |  |  | manufacturing and marketing of our products, if any.
| | - |  | ----------------------------------------------------



We will need to raise additional capital through any or all of the following: public or private financing, new collaborative
relationships, new credit facilities and/or other sources.



ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK



We are exposed to changes in interest rates primarily from our investments in certain short-term investments. We invest our excess cash in highly liquid short-term investments that are typically held
for the duration of the term of the respective instrument. We do not utilize derivative financial instruments, derivative commodity instruments or other market risk sensitive instruments to manage exposure to interest rate changes. Accordingly, we
believe that, while the securities we hold are subject to changes in the financial standing of the issuer of such securities, we are not subject to any material risks arising from changes in interest rates, foreign currency exchange rates, commodity
prices, equity prices or other market changes that affect market risk sensitive instruments.
