The attached proxy statement and notice of special meeting of stockholders describes in detail a number of proposals which require your support to enable us to complete this vital financing before our existing cash reserves are exhausted. Receipt of these funds is essential if RPI is to continue as a viable company and be able to focus our extensive skills and capabilities on our RNAi research and development programs. We believe this proposed investment represents the best opportunity available to enable existing common stockholders to have a continuing financial interest in RPI's future. THIS FINANCING WILL SIGNIFICANTLY DILUTE YOUR STOCKHOLDINGS. HOWEVER, IF STOCKHOLDERS DO NOT APPROVE THOSE PROPOSALS NECESSARY TO SECURE THE PROPOSED INVESTMENT, RPI WILL MOST LIKELY BE COMPELLED TO CEASE OPERATIONS. IN SUCH CIRCUMSTANCES OUR COMPANY WOULD BE FORCED TO LIQUIDATE WITH ALL PROCEEDS GOING TO THE PREFERRED STOCKHOLDERS. AS COMMON STOCKHOLDERS, YOU WOULD LIKELY RECEIVE NO RECOVERY WHATSOEVER, AND YOUR EXISTING SHARES WOULD BECOME WORTHLESS. As many of the items being considered require that two-thirds (66 2/3%) of all common shares vote in favor of those proposals, it is essential that each and every stockholder take the time to review the attached proxy statement and to complete and return the enclosed proxy card. YOUR VOTE IS CRITICAL, NO MATTER HOW MANY OR HOW FEW SHARES YOU OWN. Please help us to reduce the expenses associated with this solicitation by promptly returning the enclosed proxy. Any stockholder who does not return the enclosed proxy card will receive additional solicitation mailings and phone calls from our proxy solicitor. Thank you very much for your prompt attention to this important matter. PLEASE VOTE TODAY HOWARD W.

We are seeking approval of seven proposals: o Proposals One through Six relate to actions that we have agreed to take as conditions to consummating the Private Placement. Specifically, we have agreed to seek stockholder approval: o to consummate a private placement generating gross proceeds to us of $48 million involving the issuance and sale by us to investors of shares of our common stock at a per share purchase price of anywhere between $0.28 and $0.33 and warrants exercisable for shares of common stock at an exercise price of $0.42 (subject to adjustment as described herein) in transactions referred to throughout this proxy statement as the Private Placement; o to approve an amendment to our current amended and restated certificate of incorporation to effect a reverse split of our common stock of not less than 1-for-5 and not more than 1-for-15, with our board of directors having the authority to determine which, if any, of these reverse stock splits to effect within those parameters; o to approve an amendment to our current amended and restated certificate of incorporation to increase the number of authorized shares of capital stock; o to approve an amendment to our current amended and restated certificate of incorporation to change our name from Ribozyme Pharmaceuticals, Inc. to a name that better reflects our new business focus, with our board of directors having the authority to decide on an appropriate name; o to approve an amendment to our current amended and restated certificate of incorporation to permit stockholders to act by written consent in lieu of a meeting; and o to approve an amendment to our 1996 Stock Option Plan and to our 2001 Stock Option Plan as a result of which we will (a) terminate the 1996 Stock Option Plan and merge it into the 2001 Stock Option Plan, (b) increase the total number of shares reserved for issuance under the 2001 Stock Option Plan by 34 million shares (before giving effect to the proposed reverse stock split), and (c) provide a maximum limit on options granted to any individual during any calendar year, of 12 million shares. o Proposal Seven relates to approval of an amendment to our Employee Stock Purchase Plan to increase the total number of shares reserved for issuance pursuant to the plan by 5 million shares (before giving effect to the proposed reverse stock split). We describe each of these proposals in greater detail below. Q. HOW IS THE PRIVATE PLACEMENT STRUCTURED? A. On February 11, 2003, we entered into a common stock and warrant purchase agreement with the investors that provides for the issuance and sale by us to the investors of shares of our common stock and warrants to purchase shares of our common stock for aggregate proceeds of $48 million. Pursuant to the purchase agreement, we agreed to sell to the investors, and they agreed to purchase from us, 145,454,546 shares of common stock (before giving effect to the proposed reverse stock split and assuming a per share purchase price of $0.33), and five-year warrants exercisable immediately at $0.42 per share (subject to adjustment as described herein) for 30,090,909 shares of common stock (before giving effect to the proposed reverse stock split and assuming a per share purchase price of $0.33), if certain conditions are met, including the following: o Stockholder approval of Proposals One, Two, Three, Four and Six. o Our new board of directors shall consist initially of seven members, four of whom will be designated by certain of the investors, our CEO, and two other persons not affiliated with the investors. Each of these investors lose its right to board representation if its respective percentage ownership interest in RPI drops below 10%. o Each of our key employees will enter into a non-competition and non-solicitation agreement with us. o We adopt amendments to our by-laws. o We retain an executive recruiting firm acceptable to the investors to conduct a search for a senior vice president of development. o We have not undergone a material adverse effect to our business, properties, assets, liabilities, prospects or results of operation, according to standards set forth in the purchase agreement. The number of shares of common stock issued in the Private Placement (and the number of shares of common stock that may be issued upon exercise of the warrants issued as part of the Private Placement) will be subject to proportional adjustment for any changes to our capital structure, including the reverse stock split set forth in Proposal Two, but the aggregate purchase price will remain $48 million. Also, if the per share purchase price is reduced from $0.33 to $0.28, we will issue a greater number of shares of common stock and warrants to the investors. We describe the terms of the Private Placement more fully below under "Proposal One" beginning on page 6. Members of our management team holding in the aggregate approximately 98,000 shares of our common stock, or 0.48% of our outstanding common stock, have entered into voting agreements with the investors pursuant to which each has agreed, solely in its capacity as a stockholder, to vote its shares of our common stock in favor of Proposals One through Six. We describe the terms of the voting agreements below under "Proposal One" beginning on page 6. Q. WHY IS RPI SEEKING STOCKHOLDER APPROVAL FOR THE PRIVATE PLACEMENT? A. We are subject to the Nasdaq National Market rules because our common stock is listed on the Nasdaq National Market. These rules require stockholder approval for any issuance of stock that either is deemed to involve a change in control (based on certain criteria and presumptions established by Nasdaq) or is deemed to be at a price that is less than the greater of book or market value. The Private Placement will be considered a change of control of RPI under Nasdaq National Market rules. Upon consummation of the Private Placement, Oxford Bioscience Partners IV would beneficially own approximately 14.2%, The Sprout Group would beneficially own 41.8%, Venrock Associates would beneficially own 18.9%, TVM V Life Science Ventures GmbH & Co. KG would beneficially own 9.2%, and Granite Global Ventures would beneficially own 3.7%, respectively, assuming exercise in full of the warrants issued to the investors as part of the Private Placement (based on 20,285,356 shares of common stock outstanding as of February 11, 2003). In addition, certain of the new investors initially will have the right to designate a total of four of seven Board members. The remaining three Board seats will be filled by our CEO and by two persons not affiliated with the investors. Following completion of the Private Placement, the investors will hold the requisite percentage of our outstanding shares so as to permit them, if they chose to act in concert, to take actions requiring stockholder approval without obtaining the approval of our other stockholders. Q. WHY IS THE PRIVATE PLACEMENT BEING DONE? A. Early in 2002, our management and board of directors recognized our need to raise additional working capital in order to continue our clinical programs and pursue research and development. Accordingly, in March 2002, we engaged an investment bank, Raymond James & Associates ("Raymond James"), to help us identify financing alternatives. Thereafter we also decided to re-evaluate our research and clinical programs and announced our decision to focus development efforts on ANGIOZYME and research and development efforts on RNAi-based therapeutics. In line with these program changes, we put in place a plan to consolidate staffing within the company from a high of 127 in June 2002 to 70 at the present time. Nonetheless, due to the economic downturn and the effect of the downturn on the stock prices of technology-based companies, including biotech companies, we determined that it would be extremely difficult to raise additional capital through a public financing. Instead, we considered a private placement, structured as a PIPE transaction, to selected accredited investors. During this period, our market capitalization continued to decline significantly as general market conditions, especially for biotechnology and technology companies, also continued to worsen. In August 2002, we instructed Raymond James to being initial efforts, our market capitalization was approximately $12 million. Raymond James advised us that they believed it was unlikely that we would attract sufficient interest among public investors and that a financing targeting private venture capital investors had a higher likelihood of success. During this period, we also asked one of our directors, Mr. Curnock Cook, and a consultant, Bioscience Managers Limited, to explore strategic alternatives, including a potential sale of the company or of some or all of our technology. Raymond James contacted over 120 potential investors on RPI's behalf, with assistance in select instances from our consultant. Our director, our consultant and we separately contacted over ten potential strategic partners or potential acquirors regarding their interests in acquiring all or substantially all of RPI. In November 2002, after several months of exploring various financing and strategic alternatives, we entered into negotiations with the investors, led by Oxford Bioscience, The Sprout Group and Venrock Associates, with respect to the proposed Private Placement. On December 27, 2002, we received a term sheet from the investors regarding the proposed Private Placement. Negotiations regarding the term sheet continued and on January 8, 2003 we agreed to negotiate exclusively with the investors. On January 26, 2003, our board of directors met to discuss our progress in the negotiations and authorized management to continue to negotiate with the investors. On February 4, 2003, our board of directors met to consider the Private Placement. After extensive discussion of the terms and conditions, a review of the absence of alternative funding prospects and the receipt of a fairness opinion from RPI's financial advisor, Raymond James & Associates, Inc., our board of directors unanimously approved the Private Placement, subject to obtaining stockholder approval. From February 4, 2003 through February 11, 2003, we continued to negotiate with the investors. On February 11, 2003, we entered into a common stock and warrant purchase agreement with the investors. We agreed to sell to those investors, for aggregate consideration of $48 million, 145,454,546 shares (before giving effect to the proposed reverse stock split and assuming the $0.33 per share purchase price) of our common stock at a per share purchase price of anywhere between $0.28 and $0.33 and warrants exercisable at $0.42 per share (subject to adjustment as described below) for 30,090,909 shares of our common stock (before giving effect to the proposed reverse stock split and assuming the $0.33 per share purchase price). We discuss the terms of the Private Placement more fully below under "Proposal One" beginning on page 6. Q. WHY IS RPI SEEKING STOCKHOLDER APPROVAL FOR PROPOSALS ONE THROUGH SIX? A. Pursuant to the purchase agreement, the investors will not be obligated to consummate the Private Placement unless we receive stockholder approval for Proposals One, Two, Three, Four and Six. The investors in the Private Placement seek stockholder approval for Proposals One through Six for the following reasons: o The investors require us to seek stockholder approval of Proposal One because the shares of common stock and the warrants (and the shares of common stock underlying the warrants) would equal approximately 87.8% of RPI's outstanding stock (based on 20,285,356 shares outstanding as of February 11, 2003). Under applicable Nasdaq stock market rules, we are required to obtain stockholder approval for an issuance of shares in a private placement equal to or greater than 20% of an issuer's outstanding shares if the shares are to be sold at a per share price lower than the greater of the book or market price. Stockholder approval also is required for a transaction that would result in a change of control based on certain criteria and presumptions established by Nasdaq. The Private Placement would be considered a change of control under these criteria. o The investors require us to seek stockholder approval of Proposal Two because the reverse stock split is expected to have the effect, at least in the short-term, of increasing the minimum bid price of our common stock, which was at $0.29 per share as of February 11, 2003. If we are unable to maintain a $1.00 minimum bid price on our common stock, our common stock will be delisted from the Nasdaq National Market and is not likely to qualify for listing on the Nasdaq SmallCap Market. If our common stock were delisted from the Nasdaq National Market or not listed for trading on the Nasdaq SmallCap Market, trading in our common stock could decrease substantially, or cease altogether, the market price of the common stock may decline further, potentially to zero, and our stockholders could lose some or all of their investment. o The investors require us to seek stockholder approval of Proposal Three because we will not have enough shares authorized under our current amended and restated certificate of incorporation to issue the necessary shares to the investors in the Private Placement and to Elan International Services, Ltd. and, in the future, we will require additional authorized shares in order to preserve our flexibility to raise additional capital. o The investors require us to seek stockholder approval of Proposal Four amending our amended and restated certificate of incorporation in order to effectuate a name change so that we may adopt a new name that will better convey our business focus on RNAi-based therapeutics, as we discuss below. o The investors require us to seek stockholder approval of Proposal Five amending our amended and restated certificate of incorporation because our current amended and restated certificate of incorporation does not permit stockholders to act by written consent in lieu of a meeting. As a public company, convening stockholder meetings is an expensive and time-consuming process. Since the investors in the Private Placement will in the aggregate beneficially own or have holdings that will total 87.8% of our outstanding common stock upon consummation of the Private Placement, a small number of stockholders will be able to approve matters requiring stockholder approval, if the investors choose to act in concert. The investors believe that approving corporate action by written consent may, at times, be preferable to holding a special meeting. Under the terms of the purchase agreement, however, obtaining stockholder approval of Proposal Five is not a condition to closing of the Private Placement. As a result, if we fail to obtain stockholder approval for Proposal Five we may, nevertheless, proceed with the Private Placement. o The investors require us to seek stockholder approval of Proposal Six amending our 1996 Stock Option Plan and our 2001 Stock Option Plan in order to terminate the 1996 Stock Option Plan and merge it into the 2001 Stock Option Plan, increase the number of shares reserved for issuance pursuant to the 2001 Stock Option Plan by a total of 34 million shares and provide a maximum limit on options granted to any individual during any calendar year of 12 million shares. Research and development involving our RNA technology requires a unique and specialized skill set which is difficult to find in the marketplace. One of the means of providing incentives to retain such talented and experienced employees is to grant them equity in RPI. The investors believe, as do we, that having additional shares available for issuance under our option plan will be important to permit us to continue to attract and retain such talented employees and consultants. Q. WHY IS RPI SEEKING STOCKHOLDER APPROVAL FOR PROPOSAL SEVEN? A. We have agreed to seek stockholder approval for Proposal Seven in order to permit our employees to have more shares of our common stock available for purchase by them through our Employee Stock Purchase Plan. This will permit our employees to share in our future growth. Q. WHAT IF PROPOSALS ONE, TWO, THREE, FOUR, FIVE, OR SIX ARE NOT APPROVED? A. If any of Proposals One, Two, Three, Four or Six do not receive stockholder approval, the investors will not be obligated to purchase the shares of common stock and warrants in the Private Placement, and we will not be obligated to sell them the shares of common stock or warrants. In that case, we could request special relief from the Nasdaq National Market to allow the investors to proceed with the purchase of the securities. The Nasdaq National Market grants special relief based on an issuer's financial circumstances only in limited instances. There is no guarantee, however, that the Nasdaq National Market would grant such permission, or that the investors would purchase any of our securities if we do not receive stockholder approval for Proposals One, Two, Three, Four and Six. Furthermore, due to our current low stock price and the limitations imposed by the Nasdaq rules, it is unlikely that under such circumstances we will be able to raise sufficient funds to continue our clinical and research and development programs and function as a business. You should consider the fact that our current liquidity and capital resources are limited. If we do not receive the additional $48 million in the Private Placement, it is likely that we will immediately cease our clinical and research and development programs. We may be forced to consider selling some or all of our technology. However, there can be no assurance that we would be able to sell any of our technology, or that if we were able to sell some or all of our technology, that we would be able to do so on favorable terms. Ultimately, our inability to obtain additional funding through the Private Placement may require us to cease operations entirely and also would likely cause us to explore liquidation alternatives, including the initiation of bankruptcy proceedings. If we were to file for bankruptcy, then between the repayment of our debt, and the liquidation preferences associated with our preferred shares, your investment in us would decline to zero. If Proposal Five is not approved, there will be no effect on any party's obligation to consummate the Private Placement; however, we may, following completion of the Private Placement seek approval for this amendment again. If Proposal Seven is not approved, there will be no effect on any party's obligation to consummate the Private Placement, but our employees will no longer be able to purchase our shares of common stock through the Employee Stock Purchase Plan. RIBOZYME PHARMACEUTICALS, INC. ------------------- PROXY STATEMENT FOR THE SPECIAL MEETING OF STOCKHOLDERS APRIL __, 2003 ------------------- INFORMATION CONCERNING SOLICITATION AND VOTING GENERAL The enclosed proxy is solicited on behalf of the board of directors of Ribozyme Pharmaceuticals, Inc. for use at a Special Meeting of Stockholders to be held ______, April __, 2003 at __:__, local time, or at any postponement or adjournment thereof, referred to throughout this proxy statement as the Special Meeting, for the purposes set forth herein and in the accompanying Notice of Special Meeting of Stockholders. The Special Meeting will be held at our principal offices at 2950 Wilderness Place, Boulder, Colorado 80301. Our telephone number at that location is (303) 449-6500. These proxy solicitation materials were first mailed on or about March __, 2003 to all stockholders entitled to vote at the meeting. RECORD DATE AND PRINCIPAL SHARE OWNERSHIP Stockholders of record at the close of business on February 25, 2003, the record date, are entitled to notice of and to vote at the Special Meeting. On February 11, 2003, approximately 20,285,356 shares of our common stock were issued and outstanding and held of record by approximately 226 stockholders. The closing price of our common stock on February 11, 2003 as reported by The National Association of Securities Dealers, Inc. Automated Quotation National Market was $0.29 per share. REVOCABILITY OF PROXIES Any proxy given pursuant to this solicitation may be revoked by the person giving it at any time before its use by: o delivering to Marvin Tancer, Secretary (Attention: Inspector of Elections for Ribozyme Pharmaceuticals, Inc.): o a written notice of revocation, or o a duly executed proxy bearing a later date; or o attending the meeting and voting in person. VOTING AND SOLICITATION Each stockholder is entitled to one vote for each share held as of the record date. The cost of soliciting proxies will be borne by us. We expect to reimburse brokerage firms and other persons representing beneficial owners of shares for their expenses in forwarding solicitation material to such beneficial owners. We have retained The Altman Group as proxy solicitors and expect to pay approximately $55,000.00 for this service. Proxies also may be solicited by certain of our directors, officers, and regular employees, without additional compensation, personally or by telephone or facsimile. QUORUM; ABSTENTIONS; BROKER NON-VOTES Votes cast by proxy or in person at the Special Meeting will be tabulated by the Inspector of Elections appointed for the meeting and will determine whether or not a quorum is present. The required quorum for the transaction of business at the Special Meeting is a majority of the votes eligible to be cast by holders of shares of common stock issued and outstanding on the record date. Shares that are voted "FOR," "AGAINST" or "ABSTAIN" with respect to a matter are treated as being present at the Special Meeting for purposes of establishing a quorum and also are treated as shares entitled to vote at the Special Meeting with respect to such matter. While there is no definitive statutory or case law authority in Delaware as to the proper treatment of abstentions, we believe that abstentions should be counted for purposes of determining both (1) the presence or absence of a quorum for the transaction of business and (2) the total number of votes cast with respect to a proposal. In the absence of controlling precedent to the contrary, we intend to treat abstentions in this manner. Accordingly, abstentions will have the same effect as a vote against the proposal. The Delaware Supreme Court has held that, while broker non-votes (that is, votes from shares held of record by brokers as to which the beneficial owners have given no voting instructions) should be counted for purposes of determining the presence or absence of a quorum for the transaction of business, broker non-votes should not be counted for purposes of determining the number of votes cast with respect to the particular proposal on which the broker has expressly not voted. Accordingly, we intend to treat broker non-votes in this manner. Thus, a broker non-vote will not affect the outcome of the voting on a proposal. Any proxy which is returned using the form of proxy enclosed and which is not marked as to a particular item will be voted "FOR" Proposals One, Two, Three, Four, Five, Six, and Seven and as the proxy holders deem advisable on other matters that may come before the meeting, as the case may be, with respect to the items not marked. INFORMATION IN THIS PROXY STATEMENT Unless otherwise specifically noted, all of the share numbers in this proxy statement are based on 20,285,356 shares of common stock outstanding as of February 11, 2003, the date of execution of the common stock and warrant purchase agreement. When referencing the number of shares of common stock that will be owned by the investors following the Private Placement, we have taken into account the shares of common stock we will issue to the investors in the Private Placement, as well as the number of shares of common stock underlying the warrants that we will issue to the investors. Also, in our calculation of ownership percentages, we have included as outstanding o the shares of common stock that will be issued upon conversion by Elan of all of our Series A and Series B Preferred Stock currently held by Elan, o the 657,406 shares of common stock that will be issued to Elan in connection with the Private Placement, o the shares underlying warrants that we have agreed to issue to Elan in connection with the Private Placement, and o the shares underlying warrants that we have agreed to issue to Schering in connection with the Private Placement. We have not included as outstanding derivative securities held by Elan and Schering that were not issued in connection with the Private Placement. None of the share numbers give effect to the proposed reverse stock split described under Proposal Two. The Board of Directors recommends a vote "For" approval of each of the seven proposals. Delaware law contemplates that directors who have a personal financial or other interest that is different from, or in conflict with, those of the stockholders, regarding a proposal may abstain from voting to recommend the proposal. Mr. Curnock Cook abstained from the vote as our Compensation Committee previously had authorized payment of a success fee to Mr. Curnock Cook in connection with the closing of the Private Placement. Mr. Curnock Cook would have received a success fee in connection with the Private Placement because he had assisted RPI in contacting and meeting with potential investors, strategic partners and potential acquirors, as we discuss under "Proposal Number One--Background of the Private Placement." Mr. Curnock Cook has since waived this fee. Mr. Groom abstained from the vote as he represents Elan on the Board of Directors and we, at the time, were negotiating with Elan, among other things, for the conversion of preferred shares into our common stock. We discuss the terms of our arrangement with Elan under "Proposal Number One--Elan International Services, Ltd. ("Elan") Waiver." Mr. Robin abstained from voting as his employment and compensation arrangements were required to be modified as part of the Private Placement. As a result, Mr. Saks and Mr. Wiklund were the only two directors who voted and both voted to recommend a vote "For" each of the proposals. Each director who abstained stated at the time of the vote that if he were to vote, he would vote to recommend a vote "For" each of the proposals. IN THIS PROXY, WHEN YOU SEE A REFERENCE TO THE BOARD'S RECOMMENDATION, IT REFERS TO THE RECOMMENDATION OF MR. SAKS AND MR. WIKLUND. SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT As of February 13, 2003, there were 20,285,356 shares of common stock outstanding, par value $0.01, held of record by approximately 226 stockholders. The following table summarizes information regarding the beneficial ownership of our outstanding securities as of February 13, 2003 (which includes shares that may be acquired on the exercise of stock options vested or warrants exercisable through April 14, 2003), by: o each of our directors, o all individuals who have served as our chief executive officer during our last completed fiscal year ended December 31, 2002, o our four most highly compensated executives other than the chief executive officer who were serving as executive officers as of December 31, 2002, o all of our directors and executive officers as a group, and o each person or entity who is known by us to own beneficially more than 5% of the outstanding shares of common stock. Beneficial ownership is determined in accordance with rules of the Securities and Exchange Commission and includes shares over which the indicated beneficial owner exercises voting and/or investment power. Shares of common stock subject to options or warrants currently exercisable or exercisable within 60 days are deemed outstanding for computing the percentage ownership of the person holding the options but are not deemed outstanding for computing the percentage ownership of any other person. Except as otherwise indicated in the footnotes to this table, we believe that each stockholder identified in the table has sole voting and investment power with respect to all shares listed opposite their names. Unless otherwise indicated, the following officers, directors and shareholders can be reached at our principal offices.

PROPOSAL NUMBER ONE APPROVAL OF TERMS OF PRIVATE PLACEMENT BACKGROUND OF THE PRIVATE PLACEMENT Early in 2002, our management and board of directors recognized our need to raise additional working capital in order to continue our clinical programs and pursue research and development. Accordingly, in March 2002, we engaged an investment bank, Raymond James & Associates ("Raymond James"), to help us identify financing alternatives. Thereafter we also decided to re-evaluate our research and clinical programs and announced our decision to focus development efforts on ANGIOZYME and research and development efforts on RNAi-based therapeutics. In line with these program changes, we put in place a plan to consolidate staffing within the company from a high of 127 in June 2002 to 70 at the present time. Nonetheless, due to the economic downturn and the effect of the downturn on the stock prices of technology-based companies, including biotech companies, we determined that it would be extremely difficult to raise additional capital through a public financing. Instead, we considered a private placement, structured as a PIPE transaction, to selected accredited investors. During this period, our market capitalization continued to decline significantly as general market conditions, especially for biotechnology and technology companies, also continued to worsen. In August 2002, when we instructed Raymond James to begin initial marketing efforts, our market capitalization was approximately $12 million. Raymond James advised us that they believed it was unlikely that we would attract sufficient interest among public investors and that a financing targeting private venture capital investors had a higher likelihood of success. During this period, we also asked one of our directors, Mr. Curnock-Cook, and a consultant, Bioscience Managers Limited, to explore strategic alternatives, including a potential sale of the company or of some or all of our technology. Raymond James contacted over 120 potential investors on RPI's behalf, with assistance in select instances from our consultant. Our director, our consultant and we separately contacted over ten potential strategic partners or potential acquirors regarding their interests in acquiring all or substantially all of RPI. In November 2002, after several months of exploring various financing and strategic alternatives, we entered into negotiations with the investors, led by Oxford Bioscience, The Sprout Group and Venrock Associates, with respect to the proposed Private Placement. On December 27, 2002, we received a term sheet from the investors regarding the proposed Private Placement. Negotiations regarding the term sheet continued and, on January 8, 2003, we agreed to negotiate exclusively with the investors. On January 26, 2003, our board of directors met to discuss our progress in the negotiations and authorized management to continue to negotiate with the investors. On February 4, 2003, our board of directors met to consider the Private Placement. After extensive discussion of the terms and conditions, a review of the absence of alternative funding prospects and the receipt of a fairness opinion from RPI's financial advisor, Raymond James & Associates, Inc., our board of directors unanimously approved the Private Placement, subject to obtaining stockholder approval. From February 4, 2003 through February 11, 2003, we continued to negotiate with the investors. On February 11, 2003, we entered into a common stock and warrant purchase agreement with the investors. We agreed to sell to those investors, for aggregate consideration of $48 million, 145,454,546 shares (before giving effect to the proposed reverse stock split and assuming the $0.33 per share purchase price) of our common stock at a per share purchase price of anywhere between $0.28 and $0.33 and warrants exercisable at $0.42 per share (subject to adjustment as described below) for 30,090,909 shares of our common stock (before giving effect to the proposed reverse stock split and assuming the $0.33 per share purchase price). We discuss the terms of the Private Placement below. We also discuss below under "Advantages and Disadvantages of the Private Placement" in this section the absence of other financing alternatives given our experiences over the past year. TERMS OF THE PRIVATE PLACEMENT The stockholders are being asked to approve the private issuance and sale by RPI of 145,454,546 shares (before giving effect to the proposed reverse stock split) of its common stock at an assumed purchase price of $0.33 per share (or 171,428,571 shares of common stock at an assumed purchase price of $0.28 per share) and warrants exercisable for 30,090,909 shares of common stock at an assumed purchase price of $0.33 per share (before giving effect to the proposed reverse stock split) at $0.42 per share (subject to adjustment as described below) (or warrants exercisable for 35,285,714 shares of common stock at an assumed purchase price of $0.28 per share) for aggregate consideration of $48 million subject to the terms and conditions outlined below. This sale of common stock and warrants is intended to be exempt from the registration requirements of the Securities Act of 1933, as amended, and we expect to rely upon the Regulation D "safe harbor" provisions. This private placement, referred to as the Private Placement throughout this proxy statement, is subject to the fulfillment of conditions that we describe below. We have set forth below the major terms of the Private Placement. THIS SUMMARY OF THE TERMS OF THE PRIVATE PLACEMENT IS INTENDED TO PROVIDE YOU WITH BASIC INFORMATION CONCERNING THE TRANSACTION; HOWEVER, IT IS NOT A SUBSTITUTE FOR REVIEWING THE COMMON STOCK AND WARRANT PURCHASE AGREEMENT IN ITS ENTIRETY, WHICH WE HAVE INCLUDED AS ANNEX A TO THIS PROXY STATEMENT. YOU SHOULD READ THIS SUMMARY IN CONJUNCTION WITH THE AGREEMENT. NUMBER OF SHARES AND PURCHASE PRICE OF COMMON STOCK AND WARRANTS TO BE ISSUED. The amount of capital to be raised pursuant to the sale of common stock and warrants in the Private Placement is $48 million. The total aggregate purchase price to be paid by the investors for the securities is fixed at $48 million; however, the per share purchase price payable by the investors for the shares of common stock may vary from $0.28 per share to $0.33 per share. This means that the actual number of shares of common stock and, consequently, the number of warrants, that we will issue to the investors will vary depending upon the per share purchase price as we describe below. The investors have agreed to purchase shares of common stock at a purchase price of $0.33 per share, subject to reduction to $0.28 per share as we describe below. The number of shares of common stock to be purchased by each investor shall be calculated by dividing the aggregate purchase price to be paid by each investor by the per share purchase price. In addition, each investor will receive five-year warrants exercisable immediately for 20% of the number of shares of common stock purchased by such investor. Also, the investors will receive their pro rata portion (pro rata based on the aggregate purchase price paid by the investors) of additional five-year warrants for 1,000,000 shares of common stock. The number of shares of common stock and the number of shares of common stock underlying the warrants to be issued to the investors will be proportionately adjusted to reflect changes in our capital structure, including the reverse stock split set forth under Proposal Two. REPRESENTATION AND WARRANTY PURCHASE PRICE ADJUSTMENT. FAILURES IN EXCESS OF $500,000 BUT LESS THAN $1.5 MILLION. Pursuant to Section 2.1(b)(ii) of the purchase agreement, if any of our representations and warranties in the purchase agreement fail to be true and correct as of the date of the purchase agreement or as of the closing and such failure or failures alone, or in the aggregate, have an adverse effect on our net operating income, net income, cash flow, or capitalization (including the incurrence of indebtedness) in excess of $500,000 but less than $1.5 million (measured separately), then the investors shall be required to close, but the per share purchase price will be reduced by $0.05 per share to $0.28 per share. FAILURES IN EXCESS OF $1.5 MILLION OR LITIGATION. By contrast, pursuant to Section 2.1(b)(i) of the purchase agreement, if either (A) any of our representations and warranties in the purchase agreement fail to be true and correct as of the date of the purchase agreement or as of the closing and such failure or failures alone, or in the aggregate, have an adverse effect on our net operating income, net income, cash flow, or capitalization (including the incurrence of indebtedness) in excess of $1.5 million (measured separately), or (B) any of our representations and warranties in the purchase agreement with respect to litigation, except for a few specified exceptions, fail to be true and correct in all material respects as of the date of the purchase agreement or as of the closing, then the investors shall have no obligation to close. If, nonetheless, the investors choose to proceed to close, then the per share purchase price will be reduced by $0.05 to $0.28 per share. In the case of either adjustment we describe above, the purchase price reduction is $0.05 (resulting in a $0.28 per share purchase price); however, if failures are below $1.5 million, then the investors are obligated to close; whereas, if the failures exceed $1.5 million, or material litigation arises, the investors are no longer obligated to close. ADDITIONAL REMEDIES AVAILABLE. The $0.05 purchase price reduction does not function as a liquidated damages provision with respect to our breach of its representations and warranties. This means that if the $0.05 purchase price reduction is applied and the investors proceed to a closing at a purchase price of $0.28 per share, they retain their rights to seek reparation from us for damages in excess of $1.5 million suffered by the investors as a result of our breach. VOTING AGREEMENTS. The investors in the Private Placement have entered into voting agreements with certain members of our management, only in their capacity as stockholders, owning an aggregate of approximately 98,000 shares of common stock, or 0.48% of the shares outstanding as of February 11, 2003, the date of signing of the purchase agreement. The voting agreements provide that these holders will vote their shares in favor of the proposals set forth in this proxy statement. These holders also have agreed to vote their shares against any alternative proposal to acquire all or substantially all of our business, properties or other assets or purchase or to acquire 20% or more of our business, properties or other assets or capital stock or other equity interests in RPI. These holders also have agreed to vote against another action or proposal which could impede, delay, postpone or materially adversely affect any of the transactions contemplated by the purchase agreement. WARRANTS. Each investor will receive two warrants. The first warrant is exercisable immediately for 20% of the shares of common stock purchased by such investor at a per share exercise price equal to $0.42. Each investor will also receive its pro rata portion (pro rata based on the aggregate purchase price paid by the investors) of additional five-year warrants exercisable immediately for 1,000,000 shares of common stock. If the purchase price is $0.33 per share, the investors will receive warrants exercisable for a total of 30,090,909 shares of common stock. If the purchase price is reduced to $0.28 per share, the investors will receive warrants exercisable for a total of 35,285,714 shares of common stock. In any case, the number of shares of common stock underlying the warrants to be issued to the investors will be proportionately adjusted to reflect changes in our capital structure, including the reverse stock split set forth under Proposal Two. LOCK-UP AGREEMENTS. We have agreed to enter into agreements with each of our officers, continuing directors, and certain key employees, so that those stockholders will not sell or otherwise transfer or dispose of their ownership interests in RPI for a period of 180 days after the consummation of the Private Placement, other than for transfers to certain permitted transferees or in private resales. The investors also have agreed to enter into similar lock-up agreements. However, these agreements may be waived at any time by our board of directors, which, following consummation of the Private Placement, will have a majority of the directors designated by certain of the investors. REGISTRATION OBLIGATIONS. Pursuant to Section 7.1(a) of the purchase agreement, no later than five days after closing, we will prepare and file a shelf registration statement registering the resale from time to time by the investors of the common stock (including the shares of common stock received upon the exercise of the warrants) purchased from us pursuant to the agreement. The registration statement must be kept effective for at least 2 1/2 years, unless the investors re-sell all the securities registered under such registration statement prior to the expiration of such period. If the investors re-sell all of their common stock registered under the registration statement, we may discontinue the registration statement. We will bear all expenses related to the filing and maintenance of the registration statement. The investors will be responsible for underwriting discounts and selling commissions applicable to a sale of the securities registered under the registration statement. Given that we are not currently eligible to use a registration statement on Form S-3, we will be required to use a registration statement on Form S-1. REGISTRATION STATEMENT: INVESTOR INDEMNIFICATION. Pursuant to Section 7.1(d)(i) of the purchase agreement, we will indemnify each investor and certain related entities against all claims, losses, damages and liabilities arising out of (i) any untrue statement of, or any omission of, material fact in any prospectus or related document (including any related registration statement), (ii) the violation by us of any federal, state or common law rule or regulation applicable to us in connection with the shelf registration statement or any prospectus or related document, or (iii) the failure by us to fulfill any undertaking made in any such registration statement or any amendments or supplements to any such registration statement. There is no dollar cap on our potential indemnity obligation. REGISTRATION STATEMENT: COMPANY INDEMNIFICATION. Pursuant to Section 7.1(d)(ii) of the purchase agreement, the investors will indemnify us and our related entities against all claims, losses, damages and liabilities arising out of any untrue statement of, or any omission of, a material fact in any prospectus or related document (including any related registration statement) if such untrue statement or omission is made in reliance upon information provided by an investor in certain limited circumstances. Each investor's potential indemnity obligation will not exceed the net proceeds received from its sale of securities. PIGGY BACK REGISTRATION RIGHTS. Pursuant to Section 7.1(f) of the purchase agreement, during the period from the 180th day after closing until the fifth anniversary of the closing, we will provide the investors unlimited "piggy-back" registration rights with respect to any other registration statement we file with respect to our common stock. The piggy-back registration rights will be subject to normal underwriters cut-backs not to exceed 30% of the number of shares proposed to be registered by the investor. DEMAND REGISTRATION RIGHTS. Pursuant to Section 7.1(g) of the purchase agreement and in addition to the shelf registration and piggy-back registration rights, we will grant to the investors a demand registration right. The demand registration right will be effective immediately upon the withdrawal of the shelf registration statement discussed above and will be of unlimited duration. ADDITIONAL REGISTRATION RIGHTS. Pursuant to Section 7.1(h) of the purchase agreement, so long as the investors hold 15% of our outstanding common stock, we will be prohibited from granting new registration rights unless we have the consent of investors holding 66 2/3% of all common stock held by the investors. RIGHT TO APPOINT DIRECTORS. The new Board of Directors shall consist of seven members, four of whom will be designated by certain of the investors; our CEO; and two persons who must not be affiliated with the new investors. The Sprout Group will have the right to designate two directors, Oxford will have the right to designate one director, and Venrock will have the right to designate one director. Four of our five directors, Jeremy L. Curnock Cook, John Groom, Samuel R. Saks, and Anders P. Wiklund, have submitted their resignations to the board to become effective immediately upon consummation of the Private Placement. At closing, the board will then fill the four vacancies with the designees of the investors. The Sprout Group will lose its right to designate one member of the Board of Director at such time it holds less than 20% of our outstanding common stock. Each of The Sprout Group, Oxford and Venrock will continue to have the right to designate one member to the board of directors if they hold at least 10% of our outstanding common stock. INDEMNIFICATION OF INVESTORS AND OTHERS. We have agreed to enter into indemnification agreements with the investors' designees to the board of directors for the benefit of the investors and the investors' venture funds and affiliates. We also have agreed to add the investors' designees to the board of directors to our current directors' and officers' liability insurance policy, which shall provide at least $25 million of coverage. To the extent it is available on commercially reasonable terms, we also have agreed to extend our current directors' and officers' liability to cover any venture funds affiliated with any director. STOCKHOLDERS' MEETING. We have agreed to convene the Special Meeting, and our board of directors has agreed, subject to its fiduciary obligations under applicable law, to recommend that the stockholders approve Proposals One, Two, Three, Four, Five and Six. PARTICIPATION RIGHTS. Pursuant to Section 7.16 of the purchase agreement, with certain exceptions, each investor, as long as it holds 10% of the outstanding shares of our common stock or all of the shares it purchased in this transaction, will have the right to purchase its pro-rata share of any common or preferred stock or company options issued by us in the future in offerings except for public offerings and certain common or preferred stock issuances. This provision is unusual in the context of a public company. From and after the execution of the agreement, we will be prohibited from offering participation rights, rights of first refusal, or rights of first offer or similar rights to any holder or prospective holder of our securities on terms more favorable than, or in preference to, the participation rights granted to the investors. BOARD OBSERVERS. Pursuant to Section 7.20 of the purchase agreement, from execution of the agreement until closing or termination of the agreement, we will allow each of the Sprout Group, Oxford and Venrock to have a representative attend all meetings of the Board of Directors in a nonvoting observer capacity. THIRD PARTY OFFERS. Pursuant to Section 7.21 of the purchase agreement, from execution of the agreement until closing or termination of the agreement, with respect to any third-party financing or transaction that would not be considered an alternative proposal to the transactions contemplated by the agreement, we must negotiate with the investors, for a 15-day period, to allow the investors to prepare a similar financing or transaction offer. If the investors offer a similar financing or transaction, we must accept the investors' proposed transaction, if we accept any transaction. NO-SOLICITATION Pursuant to Section 7.14 of the purchase agreement, subject to the director's fiduciary obligation to consider superior proposals, RPI shall not solicit alternative proposals to the transactions contemplated by the agreement. GENERAL INDEMNIFICATION Pursuant to Section 7.12 of the purchase agreement, we will indemnify each investor and certain related entities from and against losses, claims, damages, costs and expenses ("Losses") arising out of any breach by us relating to our representations, warranties, agreements or covenants. We will have no obligation to indemnify until the investors' aggregate Losses exceed $250,000, but once this level is exceeded, investors can recover all Losses, including the $250,000. BREAK-UP FEES If we or the investors terminate the purchase agreement pursuant to Section 8.1 of the purchase agreement, all rights and obligations of the parties terminate without any liability; provided, however, that the termination will not relieve us or any investor of any liability for any breach, non-fulfillment or non-compliance with the agreement. Additionally, if we terminate the agreement to pursue an alternative transaction (or if the agreement expires on June 30, 2003, the investors are not in breach and we enter into an alternative transaction within six months) we will be required to pay a break-up fee of $250,000, plus reimburse the investors' expenses. We also must pay the investors' expenses if the agreement is terminated because stockholder approval could not be obtained. CONDITIONS TO CONSUMMATING THE PRIVATE PLACEMENT In addition to certain standard closing conditions, such as our obtaining third-party consents which must be in effect at closing, causing our counsel to deliver legal opinions, and delivering officers' certificates, the obligations of the investors to consummate the Private Placement remains subject to our fulfillment, on or before the closing, of several other closing conditions which we summarize below. You should read this summary in conjunction with the common stock and warrant purchase agreement, which is attached as Annex A to this proxy statement. ACCURACY OF OUR REPRESENTATIONS AND WARRANTIES. Pursuant to Section 5.1(a) of the purchase agreement, our representations and warranties must be true and correct as of the date of the agreement and as of the date of the closing. The failure of one or more representations and warranties to be true and correct will not breach this condition unless the failure or failures, would, or would reasonably be expected to, (i) constitute a Company Material Adverse Effect (as defined below), (ii) have an adverse effect on our net operating income or net income in excess of $1.5 million, (iii) have an adverse effect on our cash flow in excess of $1.5 million, (iv) have an adverse effect on our capitalization (including incurred indebtedness) in excess of $1.5 million (each of (i)-(iv) an "Adverse Event"). An Adverse Event does not have to occur for this condition to be breached, it is enough that an Adverse Event would reasonably be expected to occur as a result of the untrue representations and warranties. Additionally, if an untrue representation and warranty does not cause a breach of this condition, it may, nevertheless, trigger a purchase price reduction and, in any event, we will remain liable to the investors with respect to any damages resulting from or arising in connection with our breach of its representations and warranties above certain thresholds. BOARD OF DIRECTORS DESIGNEES. A total of four designees of certain of the investors will be appointed to the board of directors, effective as of the consummation of the Private Placement, such that when the Private Placement is consummated, the new board of directors is composed of four designees of those investors, two designees that are not affiliated with the investors, and our CEO. Similarly, the designees of those investors shall participate in our compensation committee and in our nominating committee. STOCKHOLDER APPROVAL. Our stockholders must have approved Proposals One, Two, Three, Four and Six as a condition to consummating the Private Placement. Obtaining stockholder approval of Proposal Five is not a condition to consummating the Private Placement. AMENDMENT TO OUR AMENDED AND RESTATED CERTIFICATE OF INCORPORATION. As a condition of closing, we shall have filed with the Secretary of State of the State of Delaware an amended and restated certificate of incorporation in substantially the form included as Annex B to this proxy statement. NON-COMPETITION AND NON-SOLICITATION AGREEMENT. As a condition to closing, each of our key employees and consultants must execute and deliver to us a non-competition and non-solicitation agreement. The agreement provides that, for a period of two and one-half years after the effective date of the common stock and warrant purchase agreement, the employee signing the agreement shall not anywhere in the United States, Colorado, or any counties in Colorado, engage, without our express prior written consent, in any business or activity in direct competition with us in one of our current fields of interest or render any services or provide any advice to a competing business. Following termination of such employee's employment with us, the employee can engage in any business or activity with a person or entity engaged in one of our current fields of interest so long as that person's or entity's principal business is not in that field of interest and the employee does not personally engage in activities in that field of interest. The agreement also provides that, for the two and one-half year period described above, each employee signing the agreement will not o with respect to our business or any activity in direct competition with us in one of our current fields of interest, solicit or divert any business, clients, customers, or partners made known to the employee during his employment with us away from us, o induce customers, clients, partners, suppliers, agents or other persons under contract or otherwise associated or doing business with us who are made known to the employee during his employment with us to reduce or alter any such association or business with us, and/or o solicit any person in our employment to terminate such employment and/or accept employment or enter into any consulting arrangement with any person or entity other than us. NO COMPANY MATERIAL ADVERSE EFFECT. Pursuant to Section 5.1(k) of the purchase agreement, no Company Material Adverse Effect (as we define below) will have occurred and no event or circumstances will have occurred or arisen that would reasonably be expected to result in a Company Material Adverse Effect. A Company Material Adverse Effect does not have to occur for there to be a failure under this condition. There will be a failure under this condition if an event occurs that would reasonably be expected to result in a Company Material Adverse Effect. A "Company Material Adverse Effect" means any effect on us that is materially adverse to our business, properties, assets, liabilities, results of operation, or prospects, including a Qualifying Restatement (as we define below), provided, that none of the following shall be deemed, either alone or in aggregate, to constitute a Company Material Adverse Effect, and none of the following shall be taken into account in determining whether there has been or would reasonably be expected to be a Company Material Adverse Effect: (a) any change in the market price or trading volume of our common stock after the date of the stock and warrant purchase agreement; (b) any adverse circumstance, change or effect resulting directly from conditions affecting the industries in which we participate in their entirety, the U.S. economy as a whole, or foreign economies as a whole in any countries where we have material operations or is conducting clinical trials; (c) any adverse circumstance, change or effect resulting directly from the announcement or pendency of the common stock and warrant purchase agreement, the disclosure or filing of the common stock and warrant purchase agreement or any other transaction documents with the SEC, the Special Meeting, any announcement or disclosure after the date hereof of our new business model or the closing (including (i) any Transaction Accounting Charge (as we define below) or (ii) any termination or breach of any partner or similar strategic relationship with the entities listed on Schedule A to the agreement and, except as provided in sub-clause (d) below, the entity listed on Schedule B to the agreement); (d) our failure, in any amounts less than the Cash Flow Trigger or the Income Statement Trigger (as we define below), to meet our internal cash flow calculations and net operating income budget (on an accrual basis) covering the period from January 1, 2003 to the closing which were made available to the investors (provided, that, for purposes of determining such change, any Transaction Accounting Charge(s) will not be taken into account, but, notwithstanding the provisions of sub-clause (c) above, the effects of any termination or breach of the relationship with the entity listed on Schedule B to the purchase agreement will be taken into account); (e) our actual reasonable investment banking and legal fees in respect of the stock and warrant purchase agreement and the other agreements and transactions contemplated hereby and thereby; (f) any adverse circumstance, change or effect resulting directly from the taking of any action by the use which the stock and warrant purchase agreement requires us to take; (g) any adverse circumstance, change or effect resulting directly from action by any regulatory authority, including the Food and Drug Administration, other than any adverse circumstance, change or effect resulting directly from the refusal of the Food and Drug Administration to file our submissions for clinical or safety issues; (h) any delisting of our common stock from Nasdaq; or (i) any adverse circumstance, change or effect resulting, directly or indirectly, from the announcement, suspension or withdrawal of the rights offering being considered by us (as discussed with the investors) if such rights offering does not exceed $5,000,000. For purposes of the definition of Company Material Adverse Effect, a "Qualifying Restatement" is any restatement of any Form 10-Q filed by us with respect to any quarterly period in 2002 or 2003 or the Form 10-K filed by us for the year ending December 31, 2002 other than any restatement (1) disclosed in the disclosure schedule to the stock and warrant purchase agreement or made prior to the date of the stock and warrant purchase agreement, (2) not resulting primarily from our failure to comply with Regulation S-X of the Rules and Regulations of the SEC, or (3) primarily resulting from our new business model or any Transaction Accounting Charges. For purposes of the definitions of Company Material Adverse Effect and Qualifying Restatement, "Transaction Accounting Charge" means any mandated or recommended accounting change or charge that is non-cash and that we demonstrate relates directly and primarily from a change in RPI's business plan, which plan was discussed and contemplated by the investors and RPI, arising from the transactions contemplated by the purchase agreement. For purposes of the definition of Company Material Adverse Effect, a "Cash Flow Trigger" means any negative effects, that either individually or when considered in the aggregate together with other such effects, exceed $500,000 on our cash flow, excluding any Transaction Accounting Charge, as determined by comparing (i) our audited financial statements for the year ended December 31, 2002 against our unaudited financial statements for the same period (including any related notes and schedules) or (ii) our actual cash flow for the period from January 1, 2003 through the closing to our projected cash flow for the same period (pursuant to projections furnished to the investors on February 11, 2003) (including any related notes and schedules). For purposes of the definition of Company Material Adverse Effect, an "Income Statement Trigger" means any negative effect, that either individually or when considered in the aggregate together with other such effects, exceed $500,000 on our net operating income or net income, excluding any Transaction Accounting Charge, as determined by comparing (i) our audited financial statements for the year ended December 31, 2002 against our unaudited financial statements for the same period (including any related notes and schedules) or (ii) our actual net operating income or net income for the period from January 1, 2003 through the closing to our projected net operating income or net income for the same period (on an accrual basis and pursuant to projections furnished to the investors on February 11, 2003) (including any related notes and schedules). EXECUTIVE RECRUITING FIRM. As a condition to closing, we have agreed to retain an executive recruiting firm acceptable to the investors to conduct a search for a senior vice president of development. AMENDMENT TO OUR BYLAWS. We have agreed to amend our current amended bylaws to require a nominating and governance committee, compensation committee, and audit committee, and to limit our ability to undertake certain enumerated corporate actions without the approval of a majority of the total number of directors then in office. Following the transaction contemplated by the purchase agreement, we will be required to obtain the vote of a majority of our board of directors in order to take certain actions, including: o Authorizing, offering, selling or issuing any equity or debt securities; o Incurring indebtedness for borrowed money in excess of $500,000; o Granting a security interest in RPI assets, which individually or in the aggregate have value in excess of $500,000; o Selling, leasing, sublicensing or otherwise transferring any of our rights in any material intellectual property; o Purchasing, licensing or acquiring rights in any material intellectual property relating to pharmaceuticals or biologics; o Approving any annual business plan or budget or any material revisions thereto; and o Hiring or terminating any executive officer. STOCKHOLDER APPROVAL AND POTENTIAL CHANGE OF CONTROL We are required to seek stockholder approval for this Proposal One because our common stock is listed on the Nasdaq National Market, and as a result, we are subject to the Nasdaq stock market rules. These rules require stockholder approval for any issuance of stock which either is deemed to involve a change in control (based on certain criteria and presumptions established by Nasdaq) or is deemed to be at a price per share that is less than the greater of book or market value. The Private Placement would be considered a change of control of RPI as defined under the Nasdaq stock market rules. Upon consummation of the Private Placement and assuming exercise in full of the warrants issued to the investors in the Private Placement, Oxford Bioscience Partners IV would beneficially own approximately 14.2%, The Sprout Group would beneficially own approximately 41.8%, Venrock Associates would beneficially own approximately 18.9%, TVM V Life Science Ventures GmbH & Co. KG would beneficially own approximately 9.2%, and Granite Ventures would beneficially own approximately 3.7% of the shares outstanding after consummation of the Private Placement (based on 20,285,356 shares of common stock outstanding as of February 11, 2003). In addition, The Sprout Group, Oxford and Venrock will have the right to nominate a total of four of seven members of the new board of directors. ELAN INTERNATIONAL SERVICES, LTD. ("ELAN") WAIVER In connection with the common stock and warrant purchase agreement, Elan has agreed (i) to convert its Series A Preferred Stock and Series B Preferred Stock, including any accrued and unpaid dividends, into an aggregate of 2,594,168 shares of our common stock; (ii) to waive certain pre-emptive rights with respect to the Private Placement; and (iii) to waive its contractual right to nominate a director for election to our Board. As consideration for Elan's agreement, we agreed, among other things, (i) to issue to Elan an additional 657,406 shares of our common stock and five-year warrants exercisable for 514,310 shares of our common stock at a price of $0.42 per share; (ii) that the number of shares of common stock and warrants issued to Elan and the exercise price of the warrants would be adjusted to account for any forward or reverse stock split or other reclassification or recapitalization of our securities; (iii) to grant Elan the same participation rights (on a pro rata basis) granted to the investors pursuant to the common stock and warrant purchase agreement; (iv) to use our reasonable efforts to cause all shares of our common stock held by Elan to be registered under the shelf registration statement contemplated by the common stock and warrant purchase agreement; (v) to grant Elan piggy-back registration rights with respect to any shares of common stock not registered on, or sold pursuant to, such shelf registration statement; and (vi) to maintain the effectiveness of our current registration statement with respect to Elan's current securities holdings and to register the 657,406 shares of common stock issued pursuant to clause (i) under such registration statement. The Elan waiver will be void and of no effect if the Private Placement does not close on or prior to June 30, 2003, or if the terms of the Private Placement are materially different than those provided by RPI to Elan in connection with negotiating the waiver, or if, Elan's reasonable and good faith determination, a change in the terms of the Private Placement has a material adverse effect on Elan's interests, including a decrease in the amount of new money being invested in us to below $40,000,000. SCHERING AG WAIVER We have received a waiver from Schering AG, waiving its right to declare our outstanding indebtedness to Schering AG to be in default and immediately due and payable as a result of the change in control contemplated by the common stock and warrant purchase agreement. As consideration for granting us such waiver, we agreed (i) to pay to Schering AG, within five days of the closing of the Private Placement, all accrued interest on our indebtedness as of the closing date; and (ii) to pay accrued interest on a quarterly basis after the closing date. We also agreed as follows: 1. If we receive less than $45,000,000 in net proceeds from the Private Placement, we will pay off our indebtedness to Schering AG on April 9, 2004; or 2. If we receive more than $45,000,000 in net proceeds from the Private Placement, we will issue five-year warrants to Schering AG exercisable for the purchase of 250,000 shares of our common stock at $0.42 a share (adjustable to reflect any reverse stock split) and we will pay off our indebtedness to Schering AG on January 31, 2005. Schering AG's waiver will be void and of no effect if the Private Placement is abandoned, or does not close by June 30, 2003, or if the terms of the transaction are materially different from those provided to Schering AG in connection with negotiating the waiver. As a condition to closing, the Elan and Schering AG waivers, and other consents, must be in effect at closing. USE OF PROCEEDS We will receive $48 million in gross proceeds from the Private Placement transaction. We intend to use proceeds from this transaction to fund research and development, preclinical studies and clinical trials of our product candidates. In addition, upon closing of the transaction, we will pay approximately $600,000 of accrued interest on our outstanding borrowings from Schering AG. Funds also will be used for working capital and other general corporate purposes. DILUTIVE EFFECT The Private Placement will have a highly dilutive effect on current stockholders in that the percentage ownership of current stockholders will significantly decline as a result of the Private Placement. The number of shares issued pursuant to the Private Placement will increase substantially the number of shares of common stock currently outstanding. This means that our current stockholders will own a much smaller interest in RPI as a result of the Private Placement. For purposes of example only, a stockholder who owned 10% of our outstanding stock as of February 11, 2003, would own just 1.0% of the shares outstanding immediately after the Private Placement, assuming the issuance of the following securities: o 145,454,546 shares of common stock and warrants to purchase 30,090,909 shares of common stock to the investors (assuming a per share purchase price of $0.33); o 657,406 shares of common stock and warrants exercisable for 514,310 shares of common stock to Elan; o conversion by Elan of its Series A and Series B Preferred Stock into an aggregate of 2,594,168 shares of common stock; and o warrants exercisable for 250,000 shares of common stock to Schering AG. INTEREST OF CERTAIN PERSONS IN THE PRIVATE PLACEMENT You should be aware of the interest of our executive officers who negotiated the terms of the Private Placement on our behalf. Concurrent with the execution of the purchase agreement, our President and C.E.O., Howard W. Robin, entered into a new employment agreement with RPI. The employment agreement becomes effective only upon the consummation of the Private Placement. Pursuant to the employment agreement: o he will receive an annual base salary of $345,000 subject to increase at the discretion of the Board of Directors; o he will be eligible for annual bonuses of up to 30% of his then current base salary; o he will be entitled to receive employee benefits, including term life insurance in the amount of $500,000; o the $400,000 interest-free loan he previously received from RPI will be forgiven over a specified period of time (40% of the loan already has been forgiven by RPI) and RPI also shall make a "gross-up" payment to Mr. Robin equal to his tax liability associated with such forgiveness; o upon a termination "without cause" or "for good reason," 50% of his unvested stock options shall vest, the outstanding balance of the interest-free loan shall be forgiven and RPI shall pay him the "gross-up" payment; he shall receive his base salary plus a bonus for twelve (12) months after termination, subject to (a) increase if there is a change of control of RPI within twelve (12) months of termination, or (b) decrease if he obtains other employment during the severance period; o upon a change of control of RPI, all of his unvested stock options shall vest one (1) year after the change of control, the interest-free loan will be forgiven and the "gross-up" payment will be made; and, if the change of control results in his termination, he will receive his severance payment as described above and all of his unvested stock options will vest immediately. In anticipation of the Private Placement, RPI granted Mr. Robin options to purchase 8,605,000 shares of common stock at an exercise price of $0.35. The grant of these options is contingent on the consummation of the Private Placement. Given that Mr. Robin may have interests in the Private Placement that are different from, or in conflict with, those of the RPI stockholders, Mr. Robin abstained from voting on the transaction. Mr. Robin was counted for purposes of convening a quorum of the Board of Directors; however, he did not vote on the Private Placement and related transactions. Concurrent with the execution of the purchase agreement, our Chief Financial Officer, Marvin Tancer, entered into a new employment agreement with RPI. The employment agreement becomes effective only upon the consummation of the Private Placement. Pursuant to the employment agreement: o he will receive an annual base salary of $266,000 subject to increase at the discretion of the Board of Directors; o he will be eligible for annual bonuses of up to 20% of his then current base salary; o he will be entitled to receive employee benefits, including term life insurance in the amount of $500,000; o the $200,000 interest-free loan he previously received from RPI will be forgiven over a specified period of time (20% of the loan already has been forgiven by RPI) and RPI also shall make a "gross-up" payment to Mr. Tancer equal to his tax liability associated with such forgiveness; o upon a termination "without cause" or "for good reason," his unvested stock options shall continue to vest on a monthly basis during an applicable nine (9) or twelve (12) month severance period; the outstanding balance of the interest-free loan shall be forgiven and RPI shall pay him the "gross-up" payment; he shall receive his base salary plus a bonus for nine (9) months after termination, subject to (a) increase if there is a change of control of RPI within twelve (12) months of termination, or (b) decrease if he obtains other employment during the severance period; and RPI shall continue to pay for all costs related to maintain health care coverage for him and his dependents for a period no longer than eighteen (18) months; and o upon a change of control of RPI, all of his unvested stock options shall vest immediately if he terminates his employment "for good reason" within six (6) months after the change of control or if, under some circumstances, RPI terminates his employment other than "for cause", the interest-free loan will be forgiven and the "gross-up" payment will be made, and, if the change of control results in his termination, he will receive his severance payment as described above and all of his unvested stock options will vest immediately. In anticipation of the Private Placement, RPI granted Mr. Tancer options to purchase 2,790,000 shares of common stock at an exercise price of $0.35. The grant of these options is contingent on the consummation of the Private Placement. Concurrent with the execution of the purchase agreement, our Chief Scientific Officer, Nassim Usman, entered into a new employment agreement with RPI. The employment agreement becomes effective only upon the consummation of the Private Placement. Pursuant to the employment agreement: o he will receive an annual base salary of $254,000 subject to increase at the discretion of the Board of Directors; o he will be eligible for annual bonuses of up to 20% of his then current base salary; o he will be entitled to receive employee benefits, including term life insurance in the amount of $500,000; o upon a termination "without cause" or "for good reason," his unvested stock options shall continue to vest on a monthly basis during an applicable nine (9) or twelve (12) month severance period; he shall receive his base salary plus a bonus for nine (9) months after termination, subject to (a) increase if there is a change of control of RPI within twelve (12) months of termination, or (b) decrease if he obtains other employment during the severance period; and RPI shall continue to pay for all costs related to maintain health care coverage for him and his dependents for a period no longer than eighteen (18) months; and o upon a change of control of RPI, all of his unvested stock options shall vest immediately if he terminates his employment "for good reason" within six (6) months after the change of control or if, under some circumstances, RPI terminates his employment other than "for cause", and, if the change of control results in his termination, he will receive his severance payment as described above and all of his unvested stock options will vest immediately. In anticipation of the Private Placement, RPI granted Mr. Usman options to purchase 2,825,000 shares of common stock at an exercise price of $0.35. The grant of these options is contingent on the consummation of the Private Placement. Of our remaining four directors (other than Mr. Robin), Mr. Jeremy Curnock Cook and Mr. John Groom both abstained from voting on the Private Placement and related matters brought before the board. Mr. Curnock Cook abstained from the vote as our Compensation Committee previously had authorized payment of a success fee to Mr. Curnock Cook in connection with the closing of the Private Placement. Mr. Curnock Cook would have received a success fee in connection with the Private Placement because he had assisted RPI in contacting and meeting with potential investors, strategic partners and potential acquirors, as we discuss above under "--Background of the Private Placement." Mr. Curnock Cook has since waived this fee. Mr. Groom abstained from the vote as he represents Elan on the Board of Directors and we, at the time, were negotiating with Elan, among other things, for the conversion of the Series A and Series B preferred shares held by Elan into shares of our common stock . We discuss the terms of our arrangement with Elan above under "--Elan International Services, Ltd. ("Elan") Waiver." ADVANTAGES AND DISADVANTAGES OF THE PRIVATE PLACEMENT ADVANTAGES Before voting, each stockholder should consider the fact that the Private Placement will provide additional funding, which will be critically important to our efforts to continue operations. We have never generated positive cash flows from operations. Our current liquidity and capital resources are limited. If we do not receive the additional $48 million in the Private Placement, it is likely that we will immediately cease our research and development programs. Our inability to obtain additional funding through the Private Placement ultimately may require us to cease operations and also would likely cause us to explore liquidation alternatives, including the initiation of bankruptcy proceedings. If this were to occur, between the repayment of our debt obligations, and the liquidation preferences associated with our preferred shares, your investment in us would decline to zero. DISADVANTAGES Before voting, each stockholder also should consider the following disadvantages of the Private Placement: o The investors in the Private Placement, in the aggregate, will control a total of up to approximately 87.8% of the voting power of our capital stock, and certain of the investors, in the aggregate, will have the right to nominate a total of four directors to our new board of directors. Oxford Bioscience Partners IV, The Sprout Group, Venrock Associates, TVM V Life Science Ventures GmbH & Co., KG and Granite Global Ventures would beneficially own approximately 14.2%, 41.8%, 18.9%, 9.2% and 3.7% of our shares then outstanding, respectively. o The percentage ownership of our common stock by existing stockholders will decline drastically, and the investors, if they chose to act in concert, would be able to direct our actions after the Private Placement. o We will face restrictions on certain types of corporate actions that we can take without the approval of a majority of our directors then in office. o After consummation of the Private Placement, the investors will be able to take any action, even those actions that, under Delaware law, require the affirmative vote of a supermajority of the stockholders, by written consent, without the need for a stockholders' meeting. For example, if the investors were to act in concert, although they have not indicated any present intent to do any of the following, they could decide to take us private, to sell some or all of our assets, or to effect a merger without holding a stockholder's meeting whereby the investors could force all stockholders other than the investors to take cash in exchange for their shares in RPI because the investors and their respective affiliates would beneficially own or have holdings totaling approximately 87.8% of our outstanding shares after consummation of the Private Placement. o The investors will have participation rights that will permit them to maintain their ownership interest in RPI in the future. o The existence of the investors with their significant rights may make it more difficult for us to enter into other transactions, including mergers, acquisitions or change of control transactions. o Although our common stock will continue to be quoted on a securities exchange we will differ in important respects from a publicly owned corporation in that our activities could potentially be controlled by a few investors. We are requesting in this Proposal One that the stockholders approve the terms of the Private Placement as described above, including the issuance of shares of common stock for an aggregate purchase price of $48 million at a per share purchase price of anywhere between $0.28 and $0.33 and warrants exercisable for shares of common stock at an exercise price of $0.42 per share. OPINION OF OUR FINANCIAL ADVISOR Our management retained Raymond James on March 11, 2002 to act as our financial advisor in connection with our effort to secure additional financing. We hired Raymond James based on the firm's qualifications, expertise, and reputation. On January 27, 2003, our board of directors engaged Raymond James to deliver an opinion as to the fairness, from a financial point of view, of the financing being contemplated. On February 4, 2003, Raymond James delivered to our board of directors its opinion that, as of that date, the consideration to be received by RPI pursuant to the draft stock and warrant purchase agreement dated February 1, 2003 was fair to the RPI common stockholders from a financial point of view. A copy of the Raymond James opinion is attached as Exhibit 1 to this proxy statement. While a summary of the Raymond James opinion is included below, you are urged to read the Raymond James opinion carefully in its entirety for the assumptions made, the procedures followed, the matters considered and the limits of the review made by Raymond James in connection with its opinion. Our board of directors did not impose any limitations on Raymond James with respect to the investigations made or procedures followed in rendering its opinion. Raymond James was not instructed by us to solicit, nor did it solicit or assist us in soliciting, third parties that might be interested in acquiring all or any part of us. Raymond James directed its opinion to our board of directors. The opinion does not constitute a recommendation to you as to how you should vote with respect to the financing. The opinion addresses only the fairness of the consideration to be received by RPI from a financial point of view. It does not address the merits of any alternatives to the financing. Further, it does not address our underlying decision to proceed with or affect the financing or any other aspect of the financing. In furnishing its opinion, Raymond James did not admit that it is an expert within the meaning of the term "expert" as used in the Securities Act, nor did it admit that its opinion constitutes a report or valuation within the meaning of the Securities Act and the rules and regulations promulgated under the Securities Act. The Raymond James opinion includes statements to these effects. In connection with its opinion, Raymond James, among other things, reviewed: o the financial terms and conditions of a draft of the stock and warrant purchase agreement dated February 1, 2003; o the audited financial statements of RPI as of and for the years ended December 31, 2001 and 2000; o the Annual Reports of RPI filed on Form 10-K for the year ending December 31, 2001 and the Quarterly Reports filed on Form 10-Q for the quarters ended March 31, 2002, June 30, 2002, and September 30, 2002; o the current and projected financial position, results of operations, and capital resources of RPI; o the historical market prices and trading activity of the common stock of RPI; o other financial and operating information, including projections provided by RPI management in writing; o certain other publicly available information on RPI; o historical and projected revenues, operating earnings, net income, and capitalization of RPI and certain other publicly-held biotechnology companies that Raymond James deemed to be similar to RPI; o financial and operating information for selected biotechnology company financings that Raymond James deemed to be similar, in whole or in part, to the proposed financing; o the condition of the securities markets generally and the biotechnology financing market specifically; and o the financial prospects for RPI absent the proposed financing. Raymond James also discussed with members of the senior management of RPI certain information relating to the above and other matters that it deemed relevant to its inquiry. Raymond James assumed and relied upon the accuracy and completeness of all information supplied or otherwise made available to it by RPI or any other party and did not attempt to verify independently any of such information. Raymond James did not make or obtain an independent appraisal of any of RPI's assets or liabilities (contingent or otherwise). With respect to financial projections and other information and data provided to or otherwise reviewed by or discussed with Raymond James, Raymond James assumed that such projections and other information and data had been reasonably prepared in good faith on bases reflecting the best currently available estimates and judgments of management, and Raymond James has relied upon management to advise it promptly if any information previously provided became inaccurate or was required to be updated during the period of its review. The Raymond James opinion was based on market, economic, financial, and other circumstances and conditions existing and disclosed to Raymond James as of February 4, 2003. Raymond James has not assumed any obligation to update, revise, or reaffirm its opinion. Raymond James expressed no opinion as to the underlying business decision to complete the financing, the structure or tax consequences of the transactions contemplated by the financing, or the availability or advisability of any alternatives to the financing. The Raymond James opinion did not express any opinion as to the likely trading range of RPI's common stock following the financing, which may vary depending on numerous factors that generally impact the price of securities or on the financial condition of RPI at that time. The Raymond James opinion is limited to the fairness, from a financial point of view, of the financing to the common stockholders of RPI. Raymond James expressed no opinion with respect to any other reasons, legal, business, or otherwise, that may support the decision of the RPI Board of Directors to approve or consummate the financing. The following represents a brief summary of the material financial analyses performed by Raymond James in connection with providing its opinion to our board of directors. Some of the summaries of financial analyses performed by Raymond James include information presented in tabular format. In order to understand fully the financial analyses performed by Raymond James, you should read the tables together with the text of each summary. The tables alone do not constitute a complete description of the financial analyses. Considering the data in the tables without considering the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of the financial analyses performed by Raymond James. LIQUIDATION ANALYSIS Raymond James performed a liquidation analysis based information provided by our management that without a significant infusion of capital RPI would be forced to begin a liquidation process in the first quarter of calendar year 2003 and that the company would run out of cash during the second quarter of calendar year 2003. The liquidation analysis consisted of calculating the excess cash, if any, available for distribution to RPI common stockholders in a liquidation scenario by (i) deducting RPI management's estimates of the `best case' and `worst case' value of the company's assets from (ii) the value of the company's liabilities in a liquidation scenario. RPI's liabilities in a liquidation scenario were calculated to approximate $33.3 million based upon their values as of December 31, 2002. That total consisted of amounts necessary to satisfy or repay the company's: (i) Elan plc liquidation preference; (ii) Schering AG debt; (iii) Avecia Inc. debt; and (iv) lease obligation with GE Capital Corporation. RPI management also provided Raymond James with estimates of the `best case' and `worst case' liquidation value of the company's: (i) net working capital (less amounts necessary to: (a) satisfy RPI's current liabilities; (b) fund the company's operations through a liquidation process; and (c) pay severance and related expenses); (ii) property, plant and equipment; (iii) ownership interest in atugen AG; (iv) ownership interest in Archemix Corp.; (v) ANGIOZYME program; (vi) Heptazyme program; and (vii) intellectual property. Raymond James calculated a `best case' net deficit of $19.8 million and net deficit per common share of $0.97 and a worst case net deficit of $31.1 million and net deficit per common share of $1.53 as detailed in the following table ($ in millions): VALUES IN LIQUIDATION SCENARIO BEST CASE WORST CASE ------------------------------ --------- ---------- Total liabilities $33.3 $33.3 Total assets 13.5 2.2 ------- -------- Net excess / (deficit) ($19.8) ($31.1) ======= ======= Net excess / (deficit) per share ($0.97) ($1.53) PREMIUM/DISCOUNT ANALYSIS Raymond James also performed: (i) a historical stock price analysis; (ii) an analysis comparing the gross financing price in the financing to the gross financing price in other selected financings; (iii) an analysis comparing the gross financing price in the financing to the gross financing price for a smaller subset of selected financings; and (iv) an analysis comparing the net financing price in the financing to the net financing price in other selected illustrative financings. The gross and net financing prices referenced in the following analyses assume no adjustment to the financing price due to a Company Material Adverse Effect as defined by the purchase agreement. A. HISTORICAL STOCK PRICE ANALYSIS Raymond James compared both the gross and net financing price in the proposed financing to recent market prices for RPI common stock. Raymond James determined the net financing price by deducting the pro rata value of the warrants issued in the financing from the gross financing price. Raymond James used the Black-Scholes Option Pricing Model to value the warrants being issued in the financing. Based upon a gross and net financing price of $0.33 and $0.29, respectively, Raymond James determined that the gross and net financing prices in the proposed financing implied the following premiums and discounts to historical RPI market prices: GROSS NET FINANCING FINANCING PRICE $0.330 PRICE PREMIUM/(DISCOUNT) TO: $0.290 Closing Stock Price January 31, 2003 $0.250 32.0% 15.9% Average Stock Price Last 5 days $0.267 23.6% 8.5% Last 10 days $0.279 18.4% 4.0% Last 15 days $0.286 15.4% 1.3% Last 30 days $0.288 14.4% 0.5% Last 60 days $0.364 (9.4%) (20.4%) Last 90 days $0.356 (7.2%) (18.5%) B. SELECTED FINANCINGS - GROSS FINANCING PRICE COMPARISON Raymond James compared the premium/(discount) of the proposed financing to the premium/(discount) paid by investors in selected biotechnology equity financings (the "Selected Financings"). In each case, Raymond James compared the gross financing price to the historical market prices one day prior and the average market prices over the 30-, 60-, and 90-day periods prior to the date each Selected Financing was announced. The financings chosen by Raymond James were public biotechnology financings that raised aggregate proceeds of $75.0 million or less and closed within the last 18 months. For comparison purposes within this broader universe of Selected Financings, the potential RPI gross financing price of $0.33 per share was used. PREMIUM / (DISCOUNT) TO ONE 30 60 90 HISTORICAL PRICES DAY DAYS DAYS DAYS ----------------- --- ---- ---- ---- RPI Financing 32.0% 14.4% (9.4%) (7.2%) Selected Financings Mean (10.2%) (13.3%) (17.0%) (17.7%) Median (9.5%) (12.4%) (19.4%) (22.2%) Maximum 31.0% 6.1% 22.7% 29.9% Minimum (45.7%) (33.5%) (49.2%) (59.0%) C. SELECTED ILLUSTRATIVE FINANCINGS - GROSS FINANCING PRICE COMPARISON Virtually all of the Selected Financings reviewed by Raymond James involved the issuance of both common stock and warrants, which Raymond James analyzed in the context of a smaller universe of seven illustrative financings (the "Selected Illustrative Financings") that it determined to be more similar to the RPI financing. Raymond James compared the premium/(discount) of the proposed RPI financing to the premium/(discount) paid by investors in the Selected Illustrative Financings. Factors cited when selecting these illustrative financings from the larger universe of selected financings included: (i) percentage of common stock sold in the financing; (ii) financing price relative to 52-week high; and (iii) pre-financing cash relative to annual `burn-rate'. Raymond James compared the gross financing price in the proposed RPI financing to the historical market prices one day prior and the average market prices over the 30-, 60-, and 90-day periods prior to the date each of the Selected Illustrative Financings was announced. PREMIUM / (DISCOUNT) TO ONE 30 60 90 HISTORICAL PRICES DAY DAYS DAYS DAYS ----------------- --- ---- ---- ---- RPI Financing 32.0% 14.4% (9.4%) (7.2%) Selected Financings Mean (5.2%) (16.3%) (25.1%) (29.1%) Median (11.0%) (20.8%) (32.6%) (39.5%) Maximum 31.0% 0.5% 16.2% 29.9% Minimum (23.6%) (26.0%) (49.2%) (59.0%) D. SELECTED ILLUSTRATIVE FINANCINGS - NET FINANCING PRICE COMPARISON Raymond James compared the premium/(discount), on a net financing price basis, of the proposed RPI financing to the premium/(discount), on a net financing price basis, paid by investors in the Selected Illustrative Financings. In both instances, the net financing price was computed by deducting the pro rata value of the warrants issued in the financing from the gross financing price of the common stock sold. Raymond James compared the net financing price in the proposed RPI financing to the historical market prices one day prior to the date each of the Selected Illustrative Financings was announced. GROSS NET FINANCING FINANCING PREMIUM / (DISCOUNT) TO CLOSING PRICE PRICE PRICE DAY PRIOR TO ANNOUNCEMENT $0.33 $0.29 ------------------------------- ----- ----- RPI Financing 32.0% 16.4% Selected Illustrative Financings Mean (6.3%) (47.5%) Median (15.1%) (53.9%) The foregoing description is only a summary of the analyses and examinations that Raymond James considered in connection with its opinion. It is not a comprehensive description of all analyses and examinations actually conducted by Raymond James. The preparation of a fairness opinion necessarily is not susceptible to partial analysis or summary description. Raymond James believes that its analyses and the summary set forth above must be considered as a whole and that selecting portions of its analyses, without considering all analyses, would create an incomplete view of the process underlying its opinion and the analyses set forth in its presentation to our board. Raymond James did not attribute any particular weight to any analysis or factor considered by it, but rather made qualitative judgments as to the significance and relevance, if any, of each analysis and factor. The fact that any specific analysis has been referred to in the summary above is not meant to indicate that this analysis was given greater weight than any other analysis. Accordingly, the ranges of valuations resulting from any particular analysis described above should not be taken to be the view of Raymond James with respect to the actual value of RPI. In performing its analyses, Raymond James made numerous assumptions with respect to industry performance, general business and economic conditions, and other matters, many of which are beyond our control. The analyses performed by Raymond James are not necessarily indicative of actual values or actual future results, which may be significantly more or less favorable than those suggested by these analyses. These analyses were prepared solely as part of the analysis performed by Raymond James with respect to the financial fairness of the financing, and were provided to our board in connection with the delivery of the Raymond James opinion. The analyses do not purport to be appraisals or to reflect the prices at which a company might actually be sold or the prices at which any securities may trade at any time in the future. Raymond James is actively engaged in the health care investment banking business and regularly undertakes the valuation of investment securities in connection with public offerings, private placements, business combinations, and similar transactions. We have agreed to pay Raymond James a fee for its financial advisory services, including $250,000 for delivery of its fairness opinion and an advisory fee contingent upon the consummation of the financing. Further, we have agreed to indemnify Raymond James, its affiliates, and their respective directors, officers, agents, consultants, employees, and controlling persons against specific liabilities, including liabilities under the federal securities laws. In the ordinary course of its business, Raymond James may trade in the securities of RPI for its own account or for the accounts of its customers and, accordingly, may at any time hold a long or short position in such securities. NEW BUSINESS MODEL Since inception in 1992, we have focused on engineering RNA-based molecules. Until recently, we focused on developing ribozyme-based therapeutics and diagnostics. As a result, we advanced three product candidates into clinical development. We continue to have a joint development program with Chiron Corporation for one of these products, ANGIOZYME(R). We own, or have exclusive licenses to use, over 180 issued or allowed patents relating to nucleic acid technology. In connection with our negotiations with the investors we have presented to our board, and our board has approved, a revised business model. With our expertise in nucleic acid technology, we will now focus on the development of a new type of nucleic acid based therapeutic based on RNA interference (RNAi). We have redirected our research to RNAi because we believe it will have the best prospects for commercial success. We are using our expertise to design, stabilize, manufacture and deliver small interfering nucleic acids (siNAs) that facilitate the process of RNAi. We believe siNA-based drugs may become important therapeutics in the future. For a complete description of our new business plan please see our Current Report on Form 8-K, filed on February 14, 2003, which is incorporated herein by reference. RIGHTS OFFERING Promptly after the closing of the Private Placement, we intend to offer to our stockholders of record on the date of mailing of this proxy statement, non-transferable rights to purchase an aggregate of $5 million of shares of newly issued common stock at a price of either $0.28 per share or $0.33 per share (depending upon the per share purchase price at which the Private Placement is completed). Each stockholder of record will receive one non-transferable right to purchase one share of our common stock for each ______ shares of common stock held by the stockholder on the rights offering record date. If a stockholder wishes to purchase additional shares in the rights offering, the stockholder may have the opportunity to do so if other stockholders do not subscribe for their rights. We believe that this rights offering will give our existing stockholders the opportunity to purchase shares of our common stock at the same price at which the investors are purchasing shares in the Private Placement. The rights offering will not include warrants. THE RIGHTS OFFERING WILL BE MADE ONLY BY MEANS OF A PROSPECTUS FILED AS PART OF A REGISTRATION STATEMENT WITH THE SECURITIES AND EXCHANGE COMMISSION. A REGISTRATION STATEMENT RELATING TO THESE SECURITIES HAS NOT YET BEEN FILED WITH THE SECURITIES AND EXCHANGE COMMISSION. THE SECURITIES MAY NOT BE SOLD NOR MAY ANY OFFER TO BUY BE ACCEPTED PRIOR TO THE TIME THE REGISTRATION STATEMENT HAS BEEN FILED AND BECOME EFFECTIVE. THIS DESCRIPTION SHALL NOT CONSTITUTE AN OFFER TO SELL OR A SOLICITATION OF AN OFFER TO BUY, NOR SHALL THERE BE ANY SALE OF THESE SECURITIES IN ANY STATE IN WHICH SUCH OFFER, SOLICITATION OR SALE WOULD BE UNLAWFUL PRIOR TO REGISTRATION OR QUALIFICATION UNDER THE SECURITIES LAWS OF SUCH STATE OR JURISDICTION. VOTE REQUIRED The affirmative vote of the holders of a majority of the common stock present in person or represented by proxy and entitled to vote at the Special Meeting will be required to approve the terms of the Private Placement, including the issuance of shares of common stock for an aggregate purchase price of $48 million at a per share purchase price of either $0.28 or $0.33 and warrants exercisable for shares of common stock at an exercise price of $0.42 per share. RECOMMENDATION OF THE BOARD OF DIRECTORS THE BOARD OF DIRECTORS OF RPI RECOMMENDS A VOTE "FOR" APPROVAL OF THE TERMS OF THE PRIVATE PLACEMENT, INCLUDING THE ISSUANCE OF SHARES OF COMMON STOCK AND WARRANTS EXERCISABLE FOR SHARES OF COMMON STOCK AT AN EXERCISE PRICE OF $0.42 PER SHARE, FOR AGGREGATE CONSIDERATION OF $48 MILLION. ASSUMING A PER SHARE PURCHASE PRICE OF $0.28, WE WILL ISSUE TO THE INVESTORS 171,428,571 SHARES OF COMMON STOCK AND WARRANTS EXERCISABLE FOR 35,285,714 SHARES OF COMMON STOCK. ASSUMING A PER SHARE PURCHASE PRICE OF $0.33, WE WILL ISSUE TO THE INVESTORS 145,454,546 SHARES OF COMMON STOCK AND WARRANTS EXERCISABLE FOR 30,090,909 SHARES OF COMMON STOCK. PROPOSAL NUMBER TWO APPROVAL OF AMENDMENT TO CERTIFICATE OF INCORPORATION TO EFFECT A REVERSE SPLIT OF OUR COMMON STOCK This proposal, if ratified, will approve an amendment to our current amended and restated certificate of incorporation for the purpose of effecting a reverse stock split of our outstanding common stock of not less than 1-for-5 and not more than 1-for-15, with our board of directors having the authority to determine which, if any, of these reverse stock splits to effectuate within the foregoing parameters. INTRODUCTION AND BOARD RECOMMENDATION Our board of directors has determined that it would be advisable to obtain the approval of the stockholders for a reverse stock split that would reduce the number of shares of our outstanding common stock in order to increase the trading price of our common stock on the Nasdaq National Market. The board of directors proposes this action because the trading price of shares of our common stock has declined below $1.00 and our failure to increase the trading price above $1.00 will result in delisting of our common stock from the Nasdaq National Market, which our board of directors believes could harm our stockholders by reducing the marketability and the liquidity of their shares. If a reverse stock split were to be implemented, the number of shares of our common stock owned by each stockholder would be reduced in the same proportion as the reduction in the total number of shares outstanding, so that the percentage of the outstanding shares owned by each stockholder would remain unchanged. However, the Private Placement, as well as with the restructuring of our relationship with Elan and with Schering AG, will cause your ownership percentage in RPI to decline substantially. Our board of directors also believes that it would be advisable to obtain the approval of stockholders for a reverse stock split because without a reverse stock split, we will not have enough shares of common stock authorized under our current amended and restated certificate of incorporation to issue to the investors in the Private Placement. If a reverse stock split were to be implemented, the number of shares of stock issuable upon consummation of the Private Placement, the number of shares of stock issuable by us to Elan, the number of warrants issuable to Schering AG and the number of shares issuable upon exercise of the warrants issued in the Private Placement, to Elan and to Schering, would be proportionately reduced to a number that would be within the number of shares of common stock currently authorized under our amended and restated certificate of incorporation. By obtaining stockholder approval of a reverse stock split at the Special Meeting, we will also have met one of the conditions to consummating the Private Placement, discussed under Proposal One of this proxy statement. The reverse stock split would be effected by filing an amended and restated certificate of incorporation, substantially in the form attached as Annex B to this proxy statement, prior to the consummation of the Private Placement. Our board of directors will decide on the exact ratio of the reverse stock split based on factors such as prevailing market conditions, prevailing trading prices of our common stock on the Nasdaq National Market and the steps that we will need to take in order to achieve compliance with the trading price requirements and other listing regulations of the Nasdaq National Market. Accordingly, the board of directors is asking that the stockholders approve a range of reverse stock splits of not less than 1-for-5 and not more than 1-for-15; and further, that the board of directors be authorized to determine which of the reverse stock splits in the specified range, if any, to implement. In determining the ratio of the reverse stock split to implement, the board will consider the trading price of our common stock and the number of round lot holders of our common stock. Based on the price of our common stock on the days leading up to the filing of the amended and restated certificate of incorporation effecting the reverse stock split, the board will select the ratio which it believes will, in accordance with Nasdaq maintenance requirements, (i) increase the trading price of our common stock sufficiently to maintain a minimum bid price of $1.00 and (ii) result in the continued existence of at least 400 stockholders of round lots. Even after we complete the Private Placement and the reverse stock split we may not be able to meet the continuing listing standards of the Nasdaq National Market. If we are delisted, we intend to apply for listing on the Nasdaq SmallCap Market. We may not meet the standards for listing on the Nasdaq SmallCap Market. A vote in favor of this Proposal Two will be a vote for approval of each of the reverse split ratios in the specified range and for the granting of authority to the board of directors to effectuate one of the reverse stock splits in the range as it deems advisable at the time the reverse stock split is to be effectuated. This Proposal Two gives the board of directors the discretion to abandon the reverse stock split if the trading price of shares of our common stock increases above the Nasdaq National Market's minimum trading price requirements prior to its implementation, or if market or other conditions make implementation of the reverse stock split inadvisable. REASONS FOR THE REVERSE STOCK SPLIT The primary purpose of the reverse stock split is to combine the outstanding shares of our common stock into a smaller number of shares so that the shares will trade at a significantly higher price per share than their recent trading prices. Since August 1, 2002, the closing bid price of shares of our common stock on the Nasdaq National Market has been below $1.00 per share. Pursuant to the Nasdaq National Market's listing requirements, the minimum bid price of shares of our common stock must be at least $1.00 per share in order to maintain listing on the Nasdaq National Market. We believe, although we cannot assure you, that the reverse stock split will enable shares of our common stock to trade, in the short term, above the $1.00 minimum bid price which is one of the requirements to maintain listing on the Nasdaq National Market. We believe that maintaining the listing of our common stock on the Nasdaq National Market is in the best interests of RPI and its stockholders. Listing on the Nasdaq National Market increases liquidity and may minimize the spread between the "bid" and "asked" prices quoted by market makers. Further, maintaining Nasdaq listing may enhance our access to capital and increase our flexibility in responding to anticipated capital requirements. As a result, the investors in the Private Placement have made receipt of stockholder approval for the reverse stock split a condition to consummating the Private Placement, as discussed under Proposal One. For the above reasons, we believe that having the ability to effectuate the reverse stock split in an effort to regain compliance with the Nasdaq listing requirements is in the best interests of RPI and its stockholders. We anticipate that, following the consummation of the reverse stock split, our common stock will trade, in the short term, at a price per share that is proportionately higher than current market prices. However, there can be no assurance that the reverse stock split, if implemented, will have the desired effect of proportionately raising our common stock price over the long term or at all. If the reverse stock split proposal is approved by the stockholders at the Special Meeting, we expect to implement it only if we believe we can comply with the listing requirements of the Nasdaq National Market or the Nasdaq SmallCap Market. Accordingly, notwithstanding approval of the reverse stock split proposal by the stockholders, the board of directors may elect to delay or even abandon entirely the reverse stock split. IMPLEMENTATION AND EFFECTS OF THE REVERSE STOCK SPLIT If the stockholders approve the reverse stock split proposal and the board of directors determines it is necessary to effectuate a reverse stock split, the board of directors would: (i) Determine which, if any, of the reverse stock splits of not less than 1-for-5 and not more than 1-for-15 is advisable, based on market and other relevant conditions and the trading prices of our common stock at that time; and (ii) Direct management to file the amended and restated certificate of incorporation with the Delaware Secretary of State that would specify that, as of the date of the filing, every five to fifteen shares (depending on the reverse stock split selected by the board of directors) of our common stock outstanding would automatically be combined and converted into one share. For example, if the board of directors selected a 1-for-5 reverse stock split, the amendment would specify that every five shares of our common stock outstanding be combined and converted into a single share. We estimate that, following the reverse stock split, we would have approximately the same number of stockholders and, except for the effect of cash payments for fractional shares as described below, the completion of the reverse stock split alone would not affect any stockholder's proportionate equity interest in RPI. Therefore, by way of example, a stockholder who owns a number of shares that, prior to the reverse stock split, represented 1% of our outstanding shares, would continue to own 1% of our outstanding shares after the reverse stock split. However, you should take into account that we will be effecting the reverse stock split in conjunction with the Private Placement and the restructuring of our Elan and Schering obligations. The combined effect of these transactions will be to reduce your ownership interest in RPI significantly. Also, the combined effect of these transactions will be to concentrate ownership of our stock in the hands of a few holders who will collectively own approximately 87.8% of our outstanding stock (based on 20,285,356 shares outstanding as of February 11, 2003). The reverse stock split alone will not affect the number of shares of common stock that the board of directors is authorized to issue by our amended and restated certificate of incorporation. However, it will have the effect of increasing the number of shares available for future issuance, because of the reduction in the number of shares that will be outstanding after giving effect to the reverse stock split. Except as disclosed in this proxy statement, we currently have no plans related to the authorized but unissued common stock. Based on the 20,285,356 shares of common stock outstanding as of February 11, 2003, the following table reflects the approximate percentage reduction in the outstanding shares of common stock and the approximate number of shares of common stock that would be outstanding as a result of the reverse stock split: AUTHORIZED BUT PROPOSED REVERSE PERCENTAGE SHARES TO BE UNISSUED SHARES OF STOCK SPLIT REDUCTION OUTSTANDING COMMON STOCK 1 for 5 80.0% 4,057,071 55,942,929 1 for 6 83.3% 3,380,893 56,619,107 1 for 7 85.7% 2,897,908 57,102,092 1 for 8 87.5% 2,535,670 57,464,330 1 for 9 88.9% 2,253,928 57,746,072 1 for 10 90.0% 2,028,536 57,971,464 1 for 11 90.9% 1,844,123 58,155,877 1 for 12 91.7% 1,690,446 58,309,554 1 for 13 92.3% 1,560,412 58,439,588 1 for 14 92.9% 1,448,954 58,551,046 1 for 15 93.3% 1,352,357 58,647,643 Even though there will not be a dilution in the percentage ownership of current stockholders solely as a result of the reverse stock split, there will be substantial dilution of such percentage ownership if the Private Placement and the restructuring of our Elan and Schering obligations are consummated shortly after effectuating the reverse stock split, with the dilutive effects more fully discussed in Proposal One. The table above does not take into account any such effects. CASH TO BE PAID FOR FRACTIONAL SHARES Whichever reverse stock split ratio is selected, implementation of a reverse stock split will result in some stockholders owning a fractional share of common stock. For example, if a 1-for-5 reverse stock split were to be implemented, the shares owned by a stockholder with 106 shares would be converted into 21 ? shares. To avoid such a result, stockholders that otherwise would be entitled to receive a fractional share of our common stock as a consequence of the reverse stock split will, instead, receive from RPI a cash payment in U.S. dollars equal to the value of that fractional share, determined on the basis of the average bid prices of our common stock on the Nasdaq National Market for the five trading days immediately preceding the effective date of the reverse stock split (as adjusted for that reverse stock split). If any stockholder owns, in total, fewer than the number of our shares to be converted into one share as a result of the reverse stock split, that stockholder's shares would be converted into a fractional share of stock and, therefore, that stockholder would receive only cash in place of the fractional share as a result of the implementation of the reverse stock split. For example, if a 1-for-5 reverse stock split is implemented then stockholders with fewer than five shares would receive only cash. See "Exchange of Stock Certificates and Payment for Fractional Shares" below. The interest of such stockholders in RPI would, therefore, be terminated, and such stockholders would have no right to share in the assets or future growth of RPI. Based on the foregoing example, each stockholder that owns five shares or more of our common stock prior to the reverse stock split will continue to own one or more shares after the reverse stock split and would continue to share in the assets and future growth of RPI as a stockholder, and any stockholder that owns fewer than five shares would receive only cash in place of the fractional share resulting from the reverse stock split. Because the maximum reverse split under this proposal would be a 1-for-15 reverse stock split, a stockholder could assure his or her continued ownership of shares of stock of RPI after the reverse split by purchasing a number of shares sufficient to increase the total number of shares that he or she owns to 15 or more. The reverse stock split will result in some stockholders owning "odd lots" of fewer than 100 shares of our common stock as a result of the reverse stock split. Brokerage commissions and other costs of transactions in odd lot shares may be higher, particularly on a per-share basis, than the cost of transactions in even multiples of 100 shares. EFFECT OF REVERSE STOCK SPLIT ON OPTIONS The number of shares subject to our outstanding common stock options also will automatically be reduced in the same ratio as the reduction in the outstanding shares. Correspondingly, the per share exercise price of those options will be increased in direct proportion to the reverse stock split ratio, so that the aggregate dollar amount payable for the purchase of the shares subject to the options will remain unchanged. For example, assume that a 1-for-5 reverse stock split is implemented and that an optionee holds options to purchase 1,000 shares at an exercise price of $1.00 per share. On the effectiveness of the 1-for-5 reverse stock split, the number of shares subject to that option would be reduced to 200 shares and the exercise price would be proportionately increased to $5.00 per share. EXCHANGE OF STOCK CERTIFICATES AND PAYMENT FOR FRACTIONAL SHARES The combination of, and reduction in, the number of our outstanding shares as a result of the reverse stock split will occur automatically on the date that the amended and restated certificate of incorporation effectuating the reverse stock split is filed with the Secretary of State of the State of Delaware referred to as the effective date, without any action on the part of our stockholders and without regard to the date that stock certificates representing the shares prior to the reverse stock split are physically surrendered for new stock certificates. EXCHANGE OF STOCK CERTIFICATES. As soon as practicable after the effective date, transmittal forms will be mailed to each holder of record of certificates for shares of our common stock to be used in forwarding such certificates for surrender and exchange for certificates representing the number of shares of our common stock such stockholder is entitled to receive as a result of the reverse stock split. The transmittal forms will be accompanied by instructions specifying other details of the exchange. Upon receipt of such transmittal form, each stockholder should surrender the certificates representing shares of our common stock prior to the reverse stock split in accordance with the applicable instructions. Each holder who surrenders certificates will receive new certificates representing the whole number of shares of our common stock that he or she holds as a result of the reverse stock split and any cash payable in lieu of a fractional share. STOCKHOLDERS SHOULD NOT SEND IN THEIR STOCK CERTIFICATES UNTIL THEY RECEIVE A TRANSMITTAL FORM FROM OUR TRANSFER AGENT. EFFECT OF FAILURE TO EXCHANGE STOCK CERTIFICATES. After the effective date, each certificate representing shares of our common stock outstanding prior to the effective date, referred to as an old certificate, will, until surrendered and exchanged as described above, be deemed, for all corporate purposes, to evidence ownership of the whole number of shares of our common stock, and the right to receive from us the amount of cash for any fractional shares, into which the shares of our common stock evidenced by such certificate have been converted by the reverse stock split. However, the holder of such unexchanged certificates will not be entitled to receive any dividends or other distributions payable by us after the effective date, until the old certificates have been surrendered. Such dividends and distributions, if any, will be accumulated, and at the time of surrender of the old certificates, all such unpaid dividends or distributions will be paid without interest. DETERMINATION OF AMOUNT OF CASH PAYABLE FOR FRACTIONAL SHARES. If the number of shares of our common stock to which a holder is entitled as a result of the reverse stock split would otherwise include a fraction, we will pay to that stockholder, in lieu of issuing fractional shares of stock, cash in an amount equal to the same fraction multiplied by the average closing price of our shares on the Nasdaq National Market for the five days immediately preceding the effective date (as adjusted for the reverse stock split). For example, if the board of directors determined to implement a 1-for-5 reverse stock split, the shares of a stockholder that owned 106 shares prior to the reverse stock split would be converted into 21 1/5 shares as a result of the reverse stock split. If the average of the pre-split closing bid prices of shares of our common stock for that five-day period was $1.00 per share, that stockholder would receive, in exchange for his stock certificates evidencing his 21 1/5 shares, a stock certificate for 21 whole shares and a check in the amount of $0.20 for his 0.2 fractional share. CERTAIN FEDERAL INCOME TAX CONSIDERATIONS The following discussion describes certain federal income tax considerations relating to the reverse stock split. This discussion is based upon the Internal Revenue Code of 1986, referred to as the Code, existing and proposed regulations thereunder, legislative history, judicial decisions, and current administrative rulings and practices, all as amended and in effect on the date of this proxy statement. Any of these authorities could be repealed, overruled, or modified at any time, possibly retroactively and, accordingly, could cause the tax consequences to vary substantially from the consequences described herein. No ruling from the Internal Revenue Service with respect to the matters discussed herein has been requested, and there is no assurance that the IRS would agree with the conclusions set forth in this discussion. All stockholders should consult with their own tax advisors. This discussion may not address certain federal income tax consequences that may be relevant to particular stockholders in light of their personal circumstances (such as persons subject to the alternative minimum tax) or to certain types of stockholders (such as dealers in securities, insurance companies, foreign individuals and entities, financial institutions, and tax-exempt entities) who may be subject to special treatment under the federal income tax laws. This discussion also does not address any tax consequences under state, local, or foreign laws. STOCKHOLDERS ARE URGED TO CONSULT THEIR TAX ADVISERS AS TO THE PARTICULAR TAX CONSEQUENCES TO THEM OF THE REVERSE STOCK SPLIT, INCLUDING THE APPLICABILITY OF ANY STATE, LOCAL, OR FOREIGN TAX LAWS, CHANGES IN APPLICABLE TAX LAWS, AND ANY PENDING OR PROPOSED LEGISLATION. TAX CONSEQUENCES TO RPI. We should not recognize any gain or loss as a result of the reverse stock split. TAX CONSEQUENCE TO STOCKHOLDERS GENERALLY. No gain or loss should be recognized by a stockholder who receives only shares of our common stock as a result of the reverse stock split. A stockholder who receives cash in lieu of a fractional share of our common stock generally should recognize capital gain or loss on an amount equal to the difference between the cash received and the stockholder's tax basis in such fractional share of our common stock. For this purpose, a stockholder's tax basis in such fractional share of our common stock will be determined as if the stockholder had actually received such fractional share and its tax basis in the pre-split common stock had been allocated as described below. A STOCKHOLDER'S TAX BASIS IN SHARES RECEIVED UPON THE REVERSE STOCK SPLIT AND HOLDING PERIOD. Except as provided above with respect to fractional shares, the aggregate tax basis of the shares of our common stock held by a stockholder following the reverse stock split will equal the stockholder's aggregate basis in the shares of our common stock held immediately prior to the reverse stock split and generally will be allocated among the shares of our common stock held following the reverse stock split on a pro rata basis. Stockholders who have used the specific identification method to identify their basis in shares of our common stock combined in the reverse stock split should consult their own tax advisors to determine their basis in the post-reverse stock split shares that they will receive in exchange therefor. The holding period of post-reverse split common sock received will include the holding period for the pre-reverse split common stock exchanged therefor. VOTE REQUIRED The affirmative vote of the holders of sixty six and two-thirds percent (66 2/3%) of the outstanding shares of common stock (approximately 13,524,000 shares, based on 20,285,356 shares of common stock outstanding on February 11, 2003) will be required to approve the reverse stock split and amendment to our current amended and restated certificate of incorporation. RECOMMENDATION OF THE BOARD OF DIRECTORS THE BOARD OF DIRECTORS OF RPI RECOMMENDS A VOTE "FOR" APPROVAL OF THE REVERSE STOCK SPLIT PROPOSAL AND THE AMENDMENT TO OUR AMENDED AND RESTATED CERTIFICATE OF INCORPORATION. PROPOSAL NUMBER THREE APPROVAL OF AMENDMENT TO OUR AMENDED AND RESTATED CERTIFICATE OF INCORPORATION TO INCREASE THE NUMBER OF AUTHORIZED SHARES Our current amended and restated certificate of incorporation authorizes us to issue 65 million shares. The total number of shares we are authorized to issue is 60 million shares of common stock and 5 million shares of preferred stock. The board of directors has approved, subject to stockholder approval, an amendment to Article IV of our current amended and restated certificate of incorporation to increase the number of authorized shares of stock from 65 million shares to 125 million shares (depending on the ratio of the reverse stock split) of which 120 million (depending on the ratio of the reverse stock split) shall be common stock and 5 million shall be preferred stock. The proposed increase in the number of authorized shares will ensure that we have enough authorized shares to issue the necessary shares of common stock to the investors in the Private Placement, issue shares of common stock to Elan in connection with restructuring our Elan obligations, reserve an appropriate number of shares of common stock for issuance pursuant to the warrants that we have committed to issue in the Private Placement and to Elan and Schering, increase the number of shares of common stock reserved for issuance pursuant to the 2001 Stock Option Plan, increase the number of shares of common stock available under the Employee Stock Purchase Plan and retain flexibility to issue additional shares of stock in the future in connection with equity offerings or strategic alliances. We have no immediate plans, arrangements, commitments, or understandings with respect to the issuance of any of the additional shares of common stock which would be authorized by the proposed amendment other than those described in this proxy. VOTE REQUIRED The affirmative vote of the holders of sixty six and two-thirds percent (66 2/3%) of the outstanding shares of common stock (approximately 13,524,000 shares, based on 20,285,356 shares of common stock outstanding on February 11, 2003) will be required to approve the reverse stock split and amendment to our current amended and restated certificate of incorporation. RECOMMENDATION OF THE BOARD OF DIRECTORS THE BOARD OF DIRECTORS OF RPI RECOMMENDS A VOTE "FOR" APPROVAL OF THE AMENDMENT TO OUR AMENDED AND RESTATED CERTIFICATE OF INCORPORATION TO INCREASE THE NUMBER OF AUTHORIZED SHARES. PROPOSAL NUMBER FOUR APPROVAL OF AMENDMENT TO CERTIFICATE OF INCORPORATION TO CHANGE OUR NAME TO A NAME THAT BETTER REFLECTS OUR NEW BUSINESS STRATEGY. The board of directors is seeking stockholder approval to amend our current amended and restated certificate of incorporation to change our name from "Ribozyme Pharmaceuticals, Inc." to a name that better reflects our new business focus. We sought additional financing in order to continue our work in the field of nucleic acid technology. We intend to use the proceeds of the Private Placement to continue work on our existing product, ANGIOZYME, and to focus on the development of a new type of nucleic acid based therapeutic using RNA interference (RNAi). We have redirected our research to RNAi because we believe it will have the best prospects for commercial success. We are using our expertise to design, stabilize, manufacture and deliver small interfering nucleic acids (siNAs) that facilitate the process of RNAi. On February 14, 2003, we filed a Current Report on Form 8-K announcing, among other things, the execution of the purchase agreement for the Private Placement and explaining our new business strategy, as well as the associated risks. Please review Exhibit 99.2 to our Form 8-K for a detailed discussion of our new business strategy. Given our shift in focus to nucleic acid based therapeutics based on RNAi, our board has approved, subject to stockholder approval, an amendment to our amended and restated certificate of incorporation to change our name from Ribozyme Pharmaceuticals, Inc. to a name that better reflects our focus on RNAi. However, we have not yet identified a new name. By approving this proposal you will be authorizing the Board to exercise its discretion to amend Article I of the current amended and restated certification of incorporation to include the new name once the new name has been identified. The board of directors unanimously adopted and approved the change of our name from "Ribozyme Pharmaceuticals, Inc." to a name that better reflects our focus on RNAi at a special meeting of the board of directors held on February 4, 2003. If the amendment is approved, RPI's management and board of directors will retain discretion over the final name change. To accomplish the name change, the Board of Directors proposes that Article I of the current amended and restated certificate of incorporation be amended to read as follows: "The name of the corporation is: [new name will be substituted]" If the amendment to our certificate of incorporation is approved, the corporate name change will become effective upon our filing of a certificate of amendment with the Delaware Secretary of State, which filing will be made promptly after the special meeting of stockholders. VOTE REQUIRED The affirmative vote of the holders of sixty-six and two-thirds percent (66 2/3%) of the outstanding shares of common stock (approximately 13,524,000 shares, based on 20,285,356 shares of common stock outstanding on February 11, 2003) will be required to approve the name change and amendment to our current amended and restated certificate of incorporation. RECOMMENDATION OF THE BOARD OF DIRECTORS THE BOARD OF DIRECTORS OF RPI RECOMMENDS A VOTE "FOR" APPROVAL OF THE NAME CHANGE AND THE AMENDMENT TO OUR AMENDED AND RESTATED CERTIFICATE OF INCORPORATION. PROPOSAL NUMBER FIVE APPROVAL OF AMENDMENT TO CERTIFICATE OF INCORPORATION TO PERMIT STOCKHOLDERS TO ACT BY WRITTEN CONSENT INTRODUCTION AND BOARD RECOMMENDATION Under our amended and restated certificate of incorporation as currently in effect, stockholders are not permitted to act by written consent in lieu of a meeting. On February 4, 2003, our board of directors approved an amendment to the amended and restated certificate of incorporation, subject to stockholder approval, to permit any action required or allowed to be taken by our stockholders at any annual or special meeting to be taken without a meeting, without prior notice and without a vote, if a consent in writing, setting forth the action so taken, is approved by the number of stockholders necessary to authorize or take such action at a meeting at which all shares entitled to vote on such action were present and voted. The investors in the Private Placement are requiring us to solicit the approval of the stockholders for this amendment to our amended and restated certificate of incorporation because RPI is a public company, and convening stockholder meetings is, therefore, an expensive and time-consuming process under applicable laws and regulations. Since the investors in the Private Placement will beneficially own or have holdings totaling approximately 87.8% of our outstanding common stock upon consummation of the Private Placement and a small number of stockholders will, therefore, be able to approve matters requiring stockholder approval, the investors believe that approving corporate action by written consent may, at times, be preferable to holding a special meeting. Although the investors in the Private Placement are requiring us to solicit approval of Proposal Five, obtaining approval of Proposal Five is not a condition to consummating the Private Placement. If we do not receive approval for Proposal Five, we will nevertheless proceed with the Private Placement, assuming all conditions to the Private Placement have either been satisfied or waived. This is in contrast to our requirement to obtain approval for Proposal One, Proposal Two, Proposal Three, Proposal Four and Proposal Six in order to proceed with the Private Placement. If we fail to receive approval for Proposal Five, we intend to seek approval for the proposal at our annual meeting. You should be aware that once we have amended our amended and restated certificate of incorporation for this purpose, actions requiring stockholder vote under applicable Delaware law may be taken without an actual meeting of stockholders. Most actions that require stockholder approval under Delaware law require either the affirmative vote of a majority of a corporation's stockholders or the affirmative vote of 66 2/3% of a corporation's stockholders. As a result, because the investors will own in aggregate 87.8% of our outstanding common stock, if they choose to act together, they will be able to effect most corporate actions requiring stockholder approval. The amendment would be effected by filing an amended and restated certificate of incorporation, substantially in the form attached as Annex B, prior to the consummation of the Private Placement. VOTE REQUIRED The affirmative vote of the holders of 66 2/3% of the outstanding shares of common stock (approximately 13,524,000 shares, based on 20,285,356 shares of common stock outstanding on February 11, 2003) will be required to approve this amendment to our current amended and restated certificate of incorporation to permit stockholders to act by written consent in lieu of a meeting. RECOMMENDATION OF THE BOARD OF DIRECTORS THE BOARD OF DIRECTORS OF RPI RECOMMENDS A VOTE "FOR" APPROVAL OF THE AMENDMENT TO THE CERTIFICATE OF INCORPORATION TO PERMIT STOCKHOLDERS TO ACT BY WRITTEN CONSENT IN LIEU OF A MEETING. PROPOSAL NUMBER SIX APPROVAL OF AN AMENDMENT AND RESTATEMENT OF THE COMPANY'S 2001 STOCK OPTION PLAN Our board of directors and stockholders have previously adopted and approved our 2001 Stock Option Plan. Under the terms of the 2001 Stock Option Plan, 3,767,154 shares of common stock had been reserved for issuance. That number includes the shares that were reserved for issuance under the 1996 Stock Option Plan. Subsequently, our stockholders approved an additional 2,000,000 shares of common stock to be reserved for issuance at our 2002 annual meeting held in May 2002. As of February 13, 2003, options to purchase 3,675,560 shares of our common stock were outstanding under our 2001 Stock Option Plan and 1996 Stock Option Plan and 1,633,664 shares remained available for future option grants and awards. On February 4, 2003, our board of directors approved an amendment and restatement of the 2001 Stock Option Plan, a copy of which is attached to this proxy statement as Annex C, subject to stockholder approval. The amended and restated 2001 Stock Option Plan provides, among other things, an increase in the shares reserved for issuance thereunder by 34 million shares, bringing the total number of shares currently issuable under the 2001 Stock Option Plan to a total of 39,309,224 shares, including shares reserved under our 1996 Stock Option Plan that are issuable under the 2001 Stock Option Plan, and a maximum limit, on the number of shares that can underlie options granted to any individual during any calendar year, of 12,000,000 shares. At this Special Meeting, stockholders are being asked to approve the amendment and restatement of the 2001 Stock Option Plan. If approved, this increase to the number of shares reserved for issuance by 34 million shares, and the maximum individual limit of 12,000,000 shares, would be proportionately adjusted for any changes to our capital structure, including the reverse stock split described under Proposal Two of this proxy statement. Our board of directors also approved terminating our 1996 Stock Option Plan and having its options covered under the 2001 Stock Option Plan. The amendment and restatement of the 2001 Stock Option Plan accomplishes this purpose. As a result, options that were issued to our employees pursuant to the 1996 Stock Option Plan will remain subject to the terms and conditions of that Plan, but will be covered by the 2001 Stock Option Plan. No new options may be granted under the 1996 Stock Option Plan. We have decided to terminate our 1996 Stock Option Plan in order to streamline and simplify the administration of our stock option program. With respect to the amendment and restatement of the 2001 Stock Option Plan, we believe that grants of stock options motivate high levels of performance and provide an effective means of recognizing employee contributions to our success. At present, all newly hired full-time employees are granted options. We believe that this policy will continue to be of great value in recruiting and retaining highly qualified technical and other key personnel. Our board of directors believes that the ability to grant options will be important to our future success by helping us to remain competitive in attracting and retaining such key personnel. DESCRIPTION OF 2001 STOCK OPTION PLAN The essential terms of the 2001 Stock Option Plan, as proposed to be amended, are as follows: PURPOSE The purpose of the 2001 Stock Option Plan, among other things, is to (1) attract and retain key officers, employees, directors and consultants, (2) motivate such individuals by means of performance-related incentives to achieve long-range performance goals, and (3) link their compensation to the long-term interests of RPI and our stockholders. The 2001 Stock Option Plan will continue in effect for its original term of ten years until 2011 unless terminated earlier pursuant to the terms of the 2001 Stock Option Plan. STOCK SUBJECT TO THE 2001 STOCK OPTION PLAN The maximum aggregate number of shares of common stock that are reserved under the 2001 Stock Option Plan is currently 5,309,224 shares, which includes 2,309,224 shares that had been reserved and are available for issuance under our 1996 Stock Option Plan. If this Proposal Six is approved by the stockholders, the aggregate number of shares of common stock that may be granted under the 2001 Stock Option Plan will be 39,309,224 million shares. Since January 1, 2003, we have granted a total of 30,710,000 options to our officers, employees and consultants. This means that even after we increase the number of shares available for option grants under the 2001 Stock Option Plan to 39,309,224 shares as part of this Proposal Six, we will have only 4,923,664 shares remaining for future option grants. In addition to the foregoing aggregate Plan limitation, the maximum number of shares that can be the subject of options granted to any individual during any calendar year may not exceed 12,000,000 shares. The shares reserved under our 2001 Stock Option Plan may be authorized, but unissued, or reacquired common stock. If an option expires or becomes unexercisable without having been exercised in full, the unexercised shares that were subject thereto will become available for future grant or sale under the 2001 Stock Option Plan. The closing price of our common stock on February 11, 2003 as reported by the Nasdaq National Market was $0.29 per share. ADMINISTRATION The 2001 Stock Option Plan is administered by a committee of the board of directors. Subject to the provisions of the 2001 Stock Option Plan, the committee has the authority, in its discretion: o to accelerate the time at which all or any part of an option may be settled or exercised; o to determine the type or types of options to be granted; o to select the employees, directors or consultants to whom options may be granted under the 2001 Stock Option Plan; o to determine the number of shares of common stock to be covered by or with respect to which payments, rights, or other matters are to be calculated in connection with each option granted under the 2001 Stock Option Plan; o to determine the terms and conditions of any option granted under the 2001 Stock Option Plan such as the exercise price, the time or times when options or stock purchase rights may be exercised (which may be based on performance criteria), any vesting acceleration or waiver of forfeiture restrictions; o to administer and interpret the terms of the 2001 Stock Option Plan and options granted pursuant to the 2001 Stock Option Plan; o to establish, amend, suspend or waive rules and regulations and appoint such agents as deemed appropriate for the proper administration of the 2001 Stock Option Plan; o to modify or amend each option; o to allow optionees to satisfy withholding tax obligations by electing to have RPI withhold from the shares to be issued upon exercise of an option that number of shares having a fair market value equal to the amount required to be withheld; o to authorize any person to execute on behalf of RPI any instrument required to effect the grant of an option previously granted by the administrator; o to determine whether, or to what extent, and under what circumstances options may be settled or exercised in cash, common stock, other securities, other options or other property, or canceled, forfeited, or suspended; o to determine whether, to what extent, and under what circumstances cash, common stock, other securities, other options or other property, and other amounts payable with respect to an option shall be deferred either automatically or at the election of the holder or of the committee; and o to make all other determinations and take any other action deemed necessary or advisable for administering the 2001 Stock Option Plan. ELIGIBILITY All employees, directors and consultants are eligible to participate in the 2001 Stock Option Plan. Stock options intended to qualify as incentive stock options within the meaning of Section 422 of the Internal Revenue Code may be granted only to employees. Non-qualified stock options, which are options not intended to qualify as incentive stock options, may be granted to employees, directors and consultants of RPI. As of February 11, 2003, there were approximately 70 employees, 4 directors, and 5 consultants. TERMS AND CONDITIONS OF OPTIONS Each option granted under the 1996 Stock Option Plan which becomes covered under the 2001 Stock Option Plan will continue to be subject to its existing terms and conditions. Each option granted pursuant to the 2001 Stock Option Plan is evidenced by a written stock option agreement between the optionee and RPI and is subject to the following terms and conditions: TERM OF OPTION. The term of each option is stated in each option agreement. In the case of an incentive stock option, the term is ten years from the date of grant or such shorter terms as may be provided in the option agreement. In the case of an incentive stock option granted to an optionee who, at the time the incentive stock option is granted, owns stock representing more than ten percent of the total combined voting power of all classes of stock of RPI or any parent or subsidiary, the term of the incentive stock option is five years from the date of grant or such shorter term as may be provided in the option agreement. EXERCISE PRICE. The per share exercise price for the shares to be issued pursuant to the exercise of an option is determined by the committee, subject to the following: (i) in the case of an incentive stock option (A) granted to an employee who, at the time the incentive stock option is granted, owns stock representing more than ten percent of the voting power of all classes of stock of RPI or any parent or subsidiary, the per share exercise price may be no less than 110% of the fair market value per share on the date of grant and (B) granted to any employee other than an employee described in (A) immediately preceding, the per share exercise price may be no less than 100% of the fair market value per share on the date of grant; (ii) in the case of a non-qualified stock option, the per share exercise price may be determined by the committee; and (iii) in the case of a non-qualified stock option intended to qualify as "performance-based compensation" within the meaning of Section 162(m) of the Internal Revenue Code, the per share exercise price may be no less than 100% of the fair market value per share on the date of grant. Notwithstanding the foregoing, any option may be granted with a per share exercise price of less than 100% of the fair market value per share on the date of grant pursuant to a merger or other corporate transaction. FORM OF PAYMENT. The committee determines the acceptable form of payment of the purchase price upon exercising an option, including the method of payment. The 2001 Stock Option Plan provides that such payment may be made in: o cash, o cash equivalents, o other shares of common stock owned for at least six months and having a fair market value on the date of surrender equal to the aggregate exercise price of the shares as to which such option is exercised, together with any applicable withholding taxes, o subject to applicable securities laws, a "cashless" exercise method through a registered broker-dealer, or o any combination of the foregoing methods of payment. EXERCISE OF OPTION. Any option granted under the 2001 Stock Option Plan is exercisable according to the terms of the 2001 Stock Option Plan and at such times and under such conditions as determined by the committee and set forth in the option agreement. TERMINATION OF RELATIONSHIP AS A SERVICE PROVIDER. The committee has full power and authority to determine the terms and conditions that apply to any option upon the termination of employment of a participant in the Plan, including a termination by us with or without cause, by a Plan participant voluntarily or by reason of death, disability or retirement and may provide such terms and conditions in the option agreement or in rules or regulations prescribed by the committee. Unless the committee determines otherwise at the time of grant, in the case of an option granted to an employee, if the employee's status changes to a consultancy status, such change would be treated as a termination for purposes of such option, except that the committee may, in its sole discretion, determine the extent (if any) to which the option will continue to vest and remain exercisable following such termination. NON-TRANSFERABILITY OF OPTIONS An option may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or distribution or, with respect to a non-qualified stock option, as may be provided by the committee in the option agreement. GRANTS TO OUTSIDE DIRECTORS The board of directors may provide that all or a portion of one or more non-employee director's compensation (including members of the committee) be payable in the form of non-qualified stock options. The board of directors shall determine the terms and conditions of such options. The board of directors, not the committee administers options granted to non-employee directors. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, DISSOLUTION, MERGER OR ASSET SALE If there shall be declared and paid a stock dividend, or if the shares shall be split-up, converted, exchanged, reclassified or in any way substituted for, an appropriate and proportionate adjustment will be made in the price, number and/or kind of security that is the subject of an outstanding option, without changing the aggregate purchase price or value of the outstanding options, and the shares available for grants under the 2001 Stock Option Plan will be similarly adjusted. In other events involving a change in our corporate structure, the committee may make such equitable adjustments as may be necessary to prevent dilution or enlargement of the rights of the holders of outstanding options. The committee, if it deems it appropriate, may adjust options granted under the 2001 Stock Option Plan to prevent dilution or enlargement of benefits or potential benefits intended to be made available under the 2001 Stock Option Plan. In the event of a change in control, if the surviving or acquiring entity refuses to assume all options outstanding under the 2001 Stock Option Plan or substitute similar options for those outstanding under the 2001 Stock Option Plan, then the exercise period for all options held by employees, directors or consultants will be accelerated prior to the change in control event. If the accelerated options are not exercised at or before the change in control event, the options will terminate upon the change of control event. AMENDMENT AND TERMINATION OF THE STOCK OPTION PLAN The board of directors may amend, alter, suspend, discontinue or terminate the 2001 Stock Option Plan or any portion of the 2001 Stock Option Plan at any time, except that stockholder approval must be obtained for any such action if such approval is necessary to comply with any tax or regulatory requirement with which the board of directors deems it desirable or necessary to comply. The committee may waive any conditions or rights under, amend any terms of, or alter, suspend, discontinue, cancel or terminate any option, either prospectively or retroactively. The committee may not adversely affect the rights of any option holder without the option holder's consent. FEDERAL INCOME TAX CONSEQUENCES INCENTIVE STOCK OPTIONS. An optionee who is granted an incentive stock option does not recognize taxable income at the time the option is granted or upon its exercise, although the exercise may subject the optionee to the alternative minimum tax. Upon a disposition of the shares more than two years after grant of the option and one year after exercise of the option, any gain or loss is treated as long-term capital gain or loss. If these holding periods are not satisfied, the optionee recognizes ordinary income at the time of disposition equal to the difference between the exercise price and the lower of (i) the fair market value of the shares at the date of the option exercise or (ii) the sale price of the shares. Any gain or loss recognized on such a premature disposition of the shares in excess of the amount treated as ordinary income is treated as long-term or short-term capital gain or loss, depending on the holding period. A different rule for measuring ordinary income upon such a premature disposition may apply if the optionee is also an officer, director, or 10% stockholder of RPI. RPI is entitled to a deduction in the same amount as the ordinary income recognized by the optionee. NON-QUALIFIED STOCK OPTIONS. An optionee does not recognize any taxable income at the time he or she is granted a non-qualified stock option. Upon exercise, the optionee recognizes taxable income generally measured by the excess of the then fair market value of the shares over the exercise price. Any taxable income recognized in connection with an option exercise by an employee of RPI is subject to tax withholding by RPI. RPI is entitled to a deduction in the same amount as the ordinary income recognized by the optionee. Upon a disposition of such shares by the optionee, any difference between the sale price and the optionee's exercise price, to the extent not recognized as taxable income as provided above, is treated as long-term or short-term capital gain or loss, depending on the holding period. The foregoing is only a summary of the effect of federal income taxation upon optionees and RPI with respect to the grant and exercise of options under the 2001 Stock Option Plan. It does not purport to be complete, and does not discuss the tax consequences of the employee, director or consultant's death or the provisions of the income tax laws of any municipality, state or foreign country in which the employee, director or consultant may reside. 2001 STOCK OPTION PLAN BENEFITS TABLE The grant of options under the 2001 Stock Option Plan to executive officers is subject to the discretion of the compensation committee. The following table sets forth certain information regarding stock options granted (share numbers have not been adjusted to reflect the reverse stock split) during the fiscal year ended December 31, 2002 to each of our executive officers, all current executive officers as a group, all current directors (who are not executive officers) as a group, and all other employees who participated in the 2001 Stock Option Plan as a group: NUMBER OF SECURITIES NAME OF INDIVIDUAL AND POSITION UNDERLYING OPTION(#) DOLLAR VALUE($)(1) Howard Robin President and Chief Executive Officer 377,000 $ 0 Marvin Tancer Vice President of Operations & Chief Financial Officer 197,500 $ 0 Nassim Usman Vice President of Research & Development & Chief Scientific Officer 161,900 $ 0 Lawrence E.

None of the options granted during the fiscal year ended December 31, 2002 have exercise prices below $0.25 per share. Since January 1, 2003, we have granted a total of 30,710,000 options to our officers, employees and consultants. This means that even after we increase the number of shares available for option grants under the 2001 Stock Option Plan to 39,309,224 shares as part of this Proposal Six, we will have only 4,923,664 shares remaining for future option grants. OPTIONS GRANTED IN CONNECTION WITH THE PRIVATE PLACEMENT In connection with the Private Placement, the board of directors and the compensation committee considered and approved, subject to stockholder approval, contingent option grants to a number of our executive officers and employees. All of these options were granted on February 11, 2003, the date on which we entered into the purchase agreement. However, the options are contingent upon the consummation of the Private Placement. All of the options are exercisable at $0.35 per share. The following table sets forth information regarding these stock options. The share numbers have not been adjusted to reflect the reverse stock split.

RECOMMENDATION OF THE BOARD OF DIRECTORS THE BOARD OF DIRECTORS OF RPI RECOMMENDS A VOTE "FOR" APPROVAL OF THE AMENDMENT AND RESTATEMENT OF OUR 2001 STOCK OPTION PLAN. PROPOSAL NUMBER SEVEN APPROVAL OF RESERVATION OF AN ADDITIONAL 5,000,000 SHARES OF COMMON STOCK UNDER OUR EMPLOYEE STOCK PURCHASE PLAN Our board of directors have previously approved our Employee Stock Purchase Plan, a copy of which is attached to this proxy statement as Annex D . Under the terms of the Employee Stock Purchase Plan, 600,000 shares of common stock were reserved for issuance. The Employee Stock Purchase Plan provides our employees with another means of participating in our growth. In March 1996 we adopted an Employee Stock Purchase Plan, which authorizes the issuance of up to 600,000 shares of our common stock to eligible employees. Generally, each offering lasts for twenty-four months, and purchases are made on each October 31 and April 30 during each offering. For example, the initial offering began on April 11, 1996, and terminated on April 30, 1999. Common stock is purchased for accounts of employees participating in the Employee Stock Purchase Plan at a price per share equal to the lower of: * 85% of the fair market value of a share of common stock on the date of commencement of participation in the offering, or * 85% of the fair market value of a share of common stock on the date of purchase. Generally, all regular employees, including executive officers, may participate in the Employee Stock Purchase Plan and may authorize payroll deductions of up to 15% of their base compensation for the purchase of common stock under the Employee Stock Purchase Plan. Our board of directors has the authority to terminate the Employee Stock Purchase Plan at its discretion. As of January 31, 2003, 572,553 shares had been issued pursuant to the Employee Stock Purchase Plan. On February 4, 2003 our board of directors approved an amendment to our Employee Stock Purchase Plan, subject to stockholder approval, to increase the number of shares reserved for issuance thereunder by a total of 5 million shares. At this Special Meeting, stockholders are being asked to approve the increase in the number of shares reserved for issuance under the Employee Stock Purchase Plan by a total of 5,000,000 shares. If approved, this increase to the number of shares reserved for issuance by 5,000,000 shares would be proportionately adjusted for any changes to our capital structure, including the reverse stock split described under Proposal Two of this proxy statement. VOTE REQUIRED The affirmative vote of the holders of a majority of the common stock votes cast at the Special Meeting will be required to approve the reservation of an additional 5,000,000 shares of common stock under the Employee Stock Purchase Plan. RECOMMENDATION OF THE BOARD OF DIRECTORS THE BOARD OF DIRECTORS OF RPI RECOMMENDS A VOTE "FOR" APPROVAL OF THE RESERVATION OF AN ADDITIONAL 5,000,000 SHARES OF COMMON STOCK UNDER THE EMPLOYEE STOCK PURCHASE PLAN. OTHER MATTERS We know of no other matters to be submitted to the meeting. If any other matters properly come before the meeting, it is the intention of the persons named in the accompanying form of proxy to vote the shares they represent as the board of directors may recommend.

At the time the Registration Statement is declared effective, each Investor shall be named as a selling securityholder in the Registration Statement and the related prospectus in such a manner as to permit such Investor to deliver such prospectus to purchasers of registered securities in accordance with applicable law. (ii) If the Registration Statement ceases to be effective for any reason at any time prior to the applicable Effectiveness Termination Date (other than because all securities registered thereunder have been resold pursuant thereto), the Company shall use its best efforts to obtain the prompt withdrawal of any order suspending the effectiveness thereof. (iii) The Company shall supplement and amend the Registration Statement if required by the rules, regulations or instructions applicable to the registration form used by the Company for such Registration Statement, if required by the Securities Act or, to the extent to which the Company does not reasonably object, as reasonably requested by Consent of the Investors. (iv) Each Investor agrees that if such Investor wishes to sell securities pursuant to the Registration Statement, it will do so only in accordance with Section 7.1 of this Agreement. (b) EXPENSES OF REGISTRATION. All Registration Expenses incurred in connection with the registrations pursuant to Section 7.1(a) shall be borne by the Company.

"Selling Expenses" shall mean all underwriting discounts and selling commissions applicable to a sale of the Registrable Securities. (c) REGISTRATION PROCEDURES. In the case of a registration, and any qualification, compliance, or effectiveness effected by the Company pursuant to this Section 7.1, the Company will keep the Investors advised in writing as to the initiation of such registration, qualification, compliance and effectiveness and as to the completion thereof. At its expense the Company will: (i) Prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection with such registration statement as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement; (ii) Furnish to the Investors such numbers of copies of a prospectus, including a preliminary prospectus, in conformity with the requirements of the Securities Act, and such other documents as they may reasonably request in order to facilitate the disposition of Registrable Securities owned by them; (iii) Use its best efforts to register and qualify the securities covered by such registration statement under such other securities or Blue Sky laws of such jurisdictions as shall be reasonably requested by the Investors, provided that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in any such states or jurisdictions; (iv) In the event of any underwritten public offering, enter into and perform its obligations under an underwriting agreement, in usual and customary form, with the managing underwriter of such offering. Each Investor participating in such underwriting shall also enter into and perform its obligations under such an agreement; (v) Notify immediately each Investor holding Registrable Securities covered by such registration statement at any time when a prospectus relating thereto is required to be delivered under the Securities Act of the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing; provided, however, that the Company shall promptly amend such Registration Statement in order to correct any untrue statement and/or ensure that such Registration Statement is not misleading; (vi) Cause all such Registrable Securities registered hereunder to be listed or included on each securities exchange or automated quotation system on which similar securities issued by the Company are then listed or included; (vii) Provide a transfer agent and registrar for all Registrable Securities registered hereunder and a CUSIP number for all such Registrable Securities, in each case not later than the effective date of such registration; and (viii) Use its best efforts to furnish, at the request of any Investor requesting registration of Registrable Securities pursuant to this Section 7.1, on the date that such Registrable Securities are delivered to the underwriters for sale in connection with a registration pursuant to this Section 7.1, if such securities are being sold through underwriters, or, if such securities are not being sold through underwriters, on the date that the registration statement with respect to such securities becomes effective, (i) an opinion, dated such date, of counsel representing the Company for the purposes of such registration, in form and substance as is customarily given in an underwritten public offering (and reasonably acceptable to the counsel for the Investors), addressed to the underwriters, if any, and to the Investors, and (ii) a letter dated such date, from the independent certified public accountants of the Company, in form and substance as is customarily given by independent certified public accountants in an underwritten public offering (and reasonably acceptable to the counsel for the Investors), addressed to the underwriters, to the extent such letter is permitted under generally recognized accounting practice. (ix) The Company shall reasonably cooperate with legal counsel selected by Consent of the Investors ("Investor Counsel") in performing the Company's obligations under this Section 7.1 and shall: (A) permit Investor Counsel to review and comment upon any offering pursuant to this Section 7.1 and to review and comment upon (1) the Registration Statement prior to its filing with the SEC and (2) all amendments and supplements thereto (except for Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K and any similar or successor reports) prior to their filing with the SEC; and (B) furnish to Investor Counsel, without charge, (1) any correspondence from the SEC or the staff of the SEC to the Company or its representatives relating to any Registration Statement, (2) promptly after the same is prepared and filed with the SEC, one copy of any Registration Statement and any amendment(s) thereto, including financial statements and schedules, all documents incorporated therein by reference and all exhibits, and (3) upon the effectiveness of any Registration Statement, one copy of the prospectus included in such Registration Statement and all amendments and supplements thereto; provided that the Company will only be responsible for reasonable fees and expenses pursuant to this Section 7.1(c) (ix). (d) INDEMNIFICATION. (i) The Company will indemnify each Investor, its officers, directors, employees, partners, affiliates, agents, representatives and legal counsel, and each person controlling (or deemed controlling) such Investor within the meaning of the Securities Act (collectively, the "Investors' Agents"), with respect to which registration, qualification or compliance has been effected pursuant to this Section 7.1, against all claims, losses, damages and liabilities (or actions in respect thereof), joint or several, arising out of or based on (i) any untrue statement (or alleged untrue statement) of a material fact contained in any prospectus, offering circular or other similar document or any amendments or supplements thereto (including any related registration statement and amendments or supplements thereto, notification or the like) incident to any such registration, qualification or compliance, or based on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which they were made, or (ii) any violation by the Company of any federal, state or common law rule or regulation applicable to the Company in connection with any such registration, qualification or compliance or the failure of the Company to fulfill any undertaking made in any registration statement or any amendments or supplements thereto, and will reimburse each Investor, and each Investors' Agent, for any legal and any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action, as incurred, provided that the Company will not be liable in any such case to the extent that any such claim, loss, damage, liability or expense arises out of or is based on any untrue statement or omission based upon written information furnished to the Company by an instrument duly executed by such Investor and stated to be specifically for use therein or furnished in writing by such Investor to the Company in response to a request by the Company stating specifically that such information will be used by the Company therein. (ii) Each Investor will indemnify, severally and not jointly, the Company, each of its directors and officers, each legal counsel and independent accountant of the Company, each person who controls the Company within the meaning of the Securities Act, any underwriter, and each other Investor, against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any such registration statement, prospectus, offering circular or other similar document, or any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which they were made, and will reimburse the Company, such directors, and officers, control persons, underwriter and each other Investor for any legal or any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action, as incurred, in each case to the extent, but only to the extent, that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in such registration statement, prospectus, offering circular or other document in reliance upon and in conformity with written information furnished in writing to the Company by an instrument duly executed by such Investor and stated to be specifically for use therein or furnished by such Investor to the Company in response to a request by the Company stating specifically that such information will be used by the Company therein; provided, however, that the indemnity agreement provided in this Section 7.1(d) (ii) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the written consent of the Investor, which consent shall not be unreasonably withheld. In no event shall an Investor's indemnification obligation exceed the net proceeds received from its sale of Registrable Securities in such offering. (iii) Each party entitled to indemnification under this Section 7.1(d) (the "Indemnified Party") shall give notice to the party required to provide indemnification (the "Indemnifying Party") promptly after such Indemnified Party has received written notice of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom, provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Party (whose approval shall not be unreasonably withheld). The Indemnified Party may participate in such defense at such party's expense; provided, however, that the Indemnifying Party shall bear the expense of such defense of the Indemnified Party if representation of both parties by the same counsel would be inappropriate due to actual or potential conflicts of interest. The failure of any Indemnified Party to give notice within a reasonable period of time as provided herein shall relieve the Indemnifying Party of its obligations under this Section 7.1(d), but only to the extent that such failure to give notice shall materially adversely prejudice the Indemnifying Party in the defense of any such claim or any such litigation. No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation. (iv) If the indemnification provided for in this Section 7.1(d) is held to be unavailable to an Indemnified Party with respect to any loss, liability, claim, damage or expense referred to therein, then the Indemnifying Party, in lieu of indemnifying such Indemnified Party hereunder, shall contribute to the amount paid or payable by such Indemnified Party as a result of such loss, liability, claim, damage, or expense in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party on the one hand and of the Indemnified Party on the other in connection with the statements or omissions that resulted in such loss, liability, claim, damage or expense as well as any other relevant equitable considerations; provided, that in no event shall any contribution by an Investor under this Section 7.1(d) exceed the net proceeds from the offering received by such Investor. The relative fault of the Indemnifying Party and of the Indemnified Party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the Indemnifying Party or by the Indemnified Party and the parties' relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or omission. (v) The obligations of the Company and each Investor under this Section 7.1 shall survive the completion of any offering of the Registrable Securities in a Registration Statement under this Section 7.1, any investigation made by or on behalf of the Indemnified Party or any officer, director or controlling Person of such Indemnified Party and will survive the transfer of securities. (e) INFORMATION BY THE INVESTOR. Each Investor shall furnish to the Company such information regarding such Investor and the distribution proposed by such Investor as the Company may reasonably request in writing and as shall be reasonably required in connection with any registration, qualification or compliance referred to in this Section 7.1. (f) PIGGY-BACK REGISTRATION. In addition to the registration rights granted above, but subject to any normal underwriter's "cut-back," which shall not exceed 30% of the number of shares proposed by each such Investor to be registered, during the period from the 180th day after the Closing until the fifth anniversary of the Closing Date, the Company shall grant the Investors unlimited "piggy-back" registration rights with respect to any other registration statement filed by the Company with respect to its Common Stock, but only to the extent that the grant or exercise of such "piggy-back" registration rights will not violate any agreement to which the Company is now a party. (g) DEMAND REGISTRATION. In addition to the registration rights granted to the Investors pursuant to Section 7.1(a) above, at any time after the Effectiveness Termination Date, one or more Investors, holding in aggregate together with its or their Affiliates at least 5% of all of the outstanding shares of the Company's Common Stock, may make one written request (the "Initiating Request") to the Company for the registration under the Securities Act of all such Investor's Registrable Securities, which request shall specify the number of shares of Common Stock to be disposed of and the proposed plan of distribution therefor. Upon the receipt of any Initiating Request for registration pursuant to this Section 7.1(g), the Company will use its best efforts to effect, at the earliest possible date (taking into account any delay that may result from any special audit required by applicable law), such registration under the Securities Act. The applicable provisions of Sections 7.1(b), (c), (d) and (e) with respect to expenses, registration procedures, indemnification and information shall apply to any registration statement filed pursuant to this Section 7.1(g). (h) PRIORITY. After the Closing and for so long as the Investors and their respective Affiliates hold at least 15% of all of the outstanding shares of the Company's Common Stock, the Company shall not grant any new registration rights unless the Company receives the consent of Investors holding at least 66 2/3% of all the Common Shares then held by the Investors. 7.2 REPORTS UNDER EXCHANGE ACT. With a view to making available to the Investors the benefits of Rule 144 promulgated under the Securities Act ("SEC Rule 144") and any other rule or regulation of the SEC that may at any time permit Investors to sell securities of the Company to the public without registration or pursuant to a resale registration statement, the Company, so long as the Investors and their respective Affiliates in the aggregate hold at least 5% of all of the outstanding shares of the Company's Common Stock, agrees to: (a) make and keep public information available, as those terms are understood and defined in SEC Rule 144, at all times so long as the Company remains subject to the periodic reporting requirements under Sections 13 or 15(d) of the Exchange Act; (b) use its best efforts to take such action as is necessary to enable the Investors to utilize Form S-3, or if Form S-3 is unavailable an appropriate resale registration statement, for the sale of their Registrable Securities; provided, that, the parties hereto acknowledge that certain requirements to use Form S-3 are by their express terms beyond the Company's control, namely, the Company's market capitalization requirements and that as of the date hereof the Company is not eligible to use Form S-3; (c) file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act; and (d) furnish to any Investor, so long as the Investor owns any Registrable Securities, forthwith upon request (i) a written statement by the Company that it has complied with the reporting requirements of the Securities Act and the Exchange Act, or that it qualifies as a registrant whose securities may be resold pursuant to Form S-3, or if Form S-3 is unavailable an appropriate resale registration statement, (ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company, and (iii) such other information as may be reasonably requested in availing any Investor of any rule or regulation of the SEC which permits the selling of any such securities without registration or pursuant to such form. 7.3 ASSIGNMENT OF RIGHTS. The rights to cause the Company to register Registrable Securities pursuant to Section 7.1 may be assigned by an Investor only to an Affiliate of such Investor or a permitted transferee of such Investor pursuant to Section 7.8 or, with the written consent of the Company, which shall not be unreasonably withheld. In the event of such assignment, the transferee shall furnish the Company written notice of such assignment, and the assignee shall agree in writing to be bound by the obligations of such Investor under this Agreement. 7.4 STOCKHOLDERS' MEETING. The Company shall, in accordance with the laws of the State of Delaware and the Company's certificate of incorporation, certificates of designation, and bylaws, as each may be amended, use its best efforts to convene a meeting of holders of Common Stock (the "Stockholders' Meeting") within 30 days (or such other time period that is mutually agreed to by the Company and the Investors) after the date of the Proxy Statement, to consider and vote upon giving Stockholder Approval. The board of directors of the Company shall recommend such approval by the stockholders (the "Company Recommendation") and shall not (i) withdraw, modify or qualify (or propose to withdraw, modify or qualify) in any manner adverse to Investors such recommendation or (ii) take any action or make any statement in connection with the Stockholders' Meeting inconsistent with such recommendation (collectively, a "Change in the Company Recommendation"); provided, however, that the board of directors of the Company may make a Change in the Company Recommendation pursuant to Section 7.14 hereof and to effect any action permitted by Section 8.1 hereof. Notwithstanding any Change in the Company Recommendation, the Company shall nonetheless cause the Stockholders' Meeting to be convened and a vote to be taken, and nothing contained herein shall be deemed to relieve the Company of such obligation unless this Agreement is terminated pursuant to Section 8.1. 7.5 PROXY STATEMENT. (a) Not later than February 22, 2003, the Company shall prepare and file with the SEC a proxy statement meeting the requirements of Section 14 of the Exchange Act and the related rules and regulations thereunder promulgated by the SEC (the "Proxy Statement") to solicit Stockholder Approval. The Company shall use its best efforts to have the Proxy Statement declared effective under the Exchange Act as promptly as reasonably practicable after such filing, and promptly mail the Proxy Statement to the stockholders of the Company. (b) The Company shall keep the Investors apprised of the status of matters relating to the Proxy Statement and the Stockholders' Meeting, including promptly furnishing the Investors and their counsel with copies of notices or other communications related to the Proxy Statement, the Stockholders' Meeting or the Transactions received by the Company from the SEC or Nasdaq. 7.6 ELECTION OF DIRECTORS.

(vi) Approve any annual business plan or budget or any material revisions thereto. (vii) Hire or terminate any executive officer of the Company, including the Chief Executive Officer and Chief Financial Officer. 7.12 INDEMNIFICATION. The Company will, to the fullest extent permitted by law, indemnify and hold harmless each Investor, and each of its Affiliates, directors, officers, agents and employees (the "Investor Indemnitees") from and against any losses, claims, damages, costs, expenses (including reasonable fees of counsel and any amounts paid in settlement effected with the Company's prior written consent) or liabilities (each a "Loss," collectively "Losses") to which the Investor Indemnitees may become subject insofar as such Losses (or Actions or Proceedings, as defined below) arise out of or in connection with, directly or indirectly, any breach or non-fulfillment of, or non-compliance with, any representations, warranties, agreements, or covenants of the Company in this Agreement or any exhibit or schedule to this Agreement. The Company will indemnify and hold harmless the Investor Indemnitees from and against any and all Losses and from and against any and all damages, costs, liabilities and attorneys' fees, incurred in defending and/or resolving such Losses, Action or Proceeding; provided, that (i) the Company is promptly notified in writing of such Action or Proceeding (provided that any failure to deliver such notice will not relieve the Company of liability under this Section 7.12 except to the extent such failure is materially prejudicial to the Company's ability to defend such Action or Proceeding), (ii) the Company will have the sole control of the defense and/or settlement of such Action or Proceeding (provided that, if representation of the Investor Indemnitees by counsel retained by the Company would be inappropriate due to any actual or potential differing interest between the Investor Indemnitee and the Company or any third party represented by such counsel, the Investor Indemnitees will have the right to retain one separate counsel, with reasonable fees and expenses to be paid by the Company), (iii) the Investor Indemnitees furnish to the Company, on reasonable request, information available to the Investor Indemnitees for such defense, (iv) the Investor Indemnitees reasonably cooperate in any defense and/or settlement thereof as long as the Company pays all of the Investor Indemnitees' reasonable out of pocket expenses and attorneys' fees, and (v) the Company shall have no indemnification obligations pursuant to this section until the aggregate amount of such Losses with respect to all Investor Indemnitees exceeds $250,000 in the aggregate, in which case such Investor Indemnitee shall be entitled to recover the full amount of all Losses. The Investor Indemnitees will not admit any such Action or Proceeding or any allegations made in such Action or Proceeding without the prior written consent of the Company (which will not be unreasonably withheld). For purposes of this Agreement, an "Action or Proceeding" means any action, suit, litigation, proceeding, mediation, arbitration or investigation or audit by any Person. 7.13 OPERATION OF BUSINESS. The Company's budget and planning for 2003 has been presented to the Investors. The Company agrees that, between the date of this Agreement and the earlier of the termination of this Agreement and the Closing Date, except as expressly contemplated by any provision of this Agreement, (i) the business of the Company shall be conducted only in, and the Company shall not take any action except in, the ordinary course of business, (ii) other than with respect to any compensation arrangement disclosed in the Company Disclosure Schedule, the Company shall not increase the compensation payable, or to become payable, to any officer or director of the Company or to enter into or amend in any material way any employment, consulting, severance or termination agreement or arrangement with any such officer or director, and (iii) the Company shall use its best efforts to preserve its business organization intact, to keep available the services of its current officers and employees, consistent with the budget and planning presented to the Investors, and to maintain its existing relations with suppliers, creditors, business partners and others having business dealings with the Company, to the end that the Company's goodwill and ongoing business shall be unimpaired at the Closing Date. 7.14 NO-SOLICITATION. (a) The Company and its directors, officers, employees, representatives and agents, including investment bankers, attorneys and accountants of the Company (the "Representatives") shall not, directly or indirectly, (i) solicit, initiate or encourage or facilitate (including by way of furnishing or disclosing nonpublic information), any inquiries or the making of any proposal or offer that constitutes, or may reasonably be expected to lead to, or a transaction to effect, any Alternative Proposal; (ii) have any discussions with or provide any confidential information or data to any Person relating to any Alternative Proposal, or negotiate with any Person concerning an Alternative Proposal, or facilitate any effort or attempt to make or implement any Alternative Proposal; (iii) agree to or endorse, or propose publicly to agree to or endorse, any Alternative Proposal, or authorize or permit any of the Company's Representatives to take any such action; or (iv) agree to or endorse, or propose to agree to or endorse, or execute or enter into, any letter of intent, agreement in principle, financing agreement, merger agreement, acquisition agreement, option agreement or other similar agreement or propose publicly to agree to do any of the foregoing relating to any Alternative Proposal. (b) Notwithstanding the foregoing or anything else in this Agreement to the contrary, the Company (and its board of directors) shall be permitted to (i) comply with applicable law with regard to an Alternative Proposal, (ii) effect a Change in the Company Recommendation or (iii) provide information in connection with, and negotiate, an unsolicited, bona fide written proposal regarding an Alternative Proposal, if and only to the extent that, in any such case referred to in clause (ii) or (iii): (i) the Stockholders' Meeting shall not have occurred; (ii) the Company's board of directors shall have determined in good faith, after considering applicable law, and acting upon the written advice of independent outside counsel, that such Alternative Proposal is superior from a financial point of view to the Transactions and effecting a Change in the Company Recommendation is required in order for the board of directors of the Company to comply with its fiduciary duties to the Company's stockholders under applicable law; and (iii) prior to providing any information or data to any Person or entering into discussions or negotiations with any Person, the Company notifies the Investors within 24 hours of receipt of any proposal or offer regarding an Alternative Proposal, or any inquiry or contact with any Person with respect thereto, such notice to include the identity of the Person making such proposal, offer, inquiry or contact, and the terms of such Alternative Proposal. (c) Subject to Section 7.21, "Alternative Proposal" means any proposal or offer from any Person other than the Investors or their Affiliates to (i) acquire all or substantially all of the business, properties, or other assets of the Company, or (ii) purchase or acquire twenty percent (20%) or more of the business, properties or other assets or capital stock or other equity interests in the Company, whether by share issuance, equity or convertible debt financing, sale of stock or assets, merger, consolidation, other business combination, tender offer or exchange offer, recapitalization, reorganization, liquidation, dissolution, license agreement, mortgage, lease or other transaction involving the Company, any division or operating or principal business unit or the Intellectual Property of the Company, on the one hand, and any other Person, on the other hand; or (iii) enter into any transaction, that if consummated, would result in any Person (or the stockholders of such Person) beneficially owning securities representing 20% or more of the total voting power of the Company (or of the surviving parent entity in such transaction). 7.15 REASONABLE EFFORTS; NOTIFICATION; REPRESENTATIONS. Subject to the other terms and conditions of this Agreement, each of the parties to this Agreement shall use reasonable efforts to take promptly, or cause to be taken, all actions, and to do promptly, or cause to be done, all things necessary, proper or advisable under applicable laws and regulations to consummate and make effective the Transactions contemplated by this Agreement. Each party to this Agreement shall give prompt notice to each other party to this Agreement upon becoming aware that any representation or warranty made by such party in this Agreement has become untrue or inaccurate or that such party has failed to comply with or satisfy in any material respect any covenant, condition or agreement to be complied with or satisfied by such party under this Agreement, in each case such that the conditions set forth in Section 5.1 or Section 6.1, as the case may be, would not be satisfied. No party to this Agreement shall take any action that would cause any representation or warranty made by such party in this Agreement to be untrue if made at Closing. 7.16 PARTICIPATION RIGHTS. (a) PARTICIPATION RIGHTS. The parties hereby agree that each Investor, so long as such Investor and its respective Affiliates hold at least 10% of all of the outstanding shares of the Company's Common Stock or holds all of the Common Shares purchased by such Investor hereunder, shall have the right (the "Participation Right"), but not the obligation, to purchase its Pro Rata Share (as defined below) of all (or any part) of any New Securities (as defined below). "Pro Rata Share" equals a fraction, (x) the numerator of which shall be the number of shares of Common Stock then owned by such Investor (or receivable by such Investor upon conversion or exchange of all then outstanding Company Options held by such investor) and (y) the denominator of which shall be the sum of (i) the total number of shares of Common Stock then outstanding plus (ii) the total number of shares of Common Stock into which all then outstanding Company Options are then convertible or are exchangeable. (b) NEW SECURITIES. For purposes of this Agreement, "New Securities" shall mean any Common Stock or preferred stock of the Company, whether now authorized or not, and Company Options; provided, however, that the term "New Securities" does not include: (i) any securities, including shares of Common Stock, to be issued pursuant to a "public offering" (as such term is determined by the rules, regulations and guidelines of the National Association of Securities Dealers) of such securities, or issued pursuant to a registration statement on a Form S-4 or S-8 or substantially equivalent successor form, or, upon the approval of a majority of the entire board of directors of the Company (i.e., a majority of the total number of directors then in office), any shares issued pursuant to registration statement and offered publicly (the parties hereto agree that merely because an offering is to be undertaken as a "take-down" from a shelf registration statement, that factor will not be the sole determinative factor as to whether such offering is a "public offering"); (ii) shares of the Common Stock (or options therefor) issued or issuable to employees, officers, directors, consultants or other service providers of the Company pursuant to stock options or other stock incentive agreements or plans approved by a majority of the Company's board of directors and not for capital-raising transactions; (iii) any securities issued upon the conversion or exercise of Company Options; (iv) any shares of Common Stock (or any other security) issued in connection with any stock split, stock dividend, combination, recapitalization or similar corporate action for which no consideration is paid or payable; (v) any shares of Common Stock (or any other security) issued in connection with (A) any corporate collaboration agreement, (B) any licensing agreement, (C) any payment or settlement of any obligation under a Company Agreement, and (D) as compensation for any services rendered to the Company; (vi) any securities issued pursuant to an acquisition of the Company approved by its board of directors by means of (A) merger or other form of corporate reorganization in which outstanding shares of the Company are exchanged for securities or other consideration issued, or caused to be issued, by the acquiring corporation or its subsidiary and pursuant to which the holders of the outstanding voting securities of the Company immediately prior to such merger or other form of corporate reorganization fail to hold equity securities representing a majority of the voting power of the Company or surviving entity immediately following such merger or other form of corporate reorganization, or (B) a sale of all or substantially all the assets of the Company approved by the Company's board of directors; (vii) any securities issued in connection with bona fide equipment financings or bona fide lease agreements; or (viii) any securities issued in transactions approved by the board of directors (i.e., a majority of the total number of directors then in office) as being excluded from the provisions of this Section 7.16. (c) PROCEDURES. (i) If the Company proposes to undertake any issuance of New Securities, it shall, prior to any such issuance, give written notice to the Investors of its bona fide intention to issue New Securities (the "Company Notice"), describing the type of New Securities proposed to be issued, the total number or quantity of New Securities proposed to be issued, and the price and the general terms upon which the Company proposes to issue such New Securities. Each Investor may elect to purchase or acquire its Pro Rata Share of such New Securities (an "Electing Party") by delivering written notice (the "Participation Notice") of its election to so purchase or acquire such New Securities at the price and upon the general terms specified in the Company Notice and stating the quantity of New Securities to be purchased (not to exceed its Pro Rata Share). The Participation Notice shall be delivered to the Company within five (5) Business Days after the date of delivery of the Company Notice, and the obligations of the Electing Party thereunder to purchase the elected number or percentage of New Securities, and the obligations of the Company to sell such New Securities to the Electing Party, shall be contingent upon the consummation of the sale or other transaction pursuant to which the New Securities are proposed to be issued. The number or amount of New Securities specified in the Participation Notice shall be subject to automatic and proportionate reduction in the event that the total number or quantity of New Securities sold by the Company is reduced below the number or quantity specified in the Company Notice. (ii) If any Investor fails to give the Participation Notice to the Company within such five (5) Business Day period, or specifies in the Participation Notice that such Investor will only purchase part, but not all, of such Investor's Pro Rata Share (a "Nonpurchasing Investor"), then such Nonpurchasing Investor shall forfeit the right hereunder to purchase that part of its Pro Rata Share of such New Securities that it did not so agree to purchase and the Company shall promptly give each Investor (if any) who has timely agreed to purchase its full Pro Rata Share of such offering of New Securities (a "Purchasing Investor") written notice of the failure of any Nonpurchasing Investor to purchase such Nonpurchasing Investor's full Pro Rata Share of such offering of New Securities (the "Overallotment Notice.") Such Overallotment Notice shall be given to each Purchasing Investor within three (3) Business Days of the expiration of the five (5) Business Day period. Each Purchasing Investor shall have a right of overallotment such that such Purchasing Investor may agree to purchase a portion of the Nonpurchasing Investor's unpurchased Pro Rata Share of such offering on a pro rata basis according to the relative Pro Rata Shares of the Purchasing Investor at any time within three (3) Business Days after receiving the Overallotment Notice. (d) FAILURE TO EXERCISE. If the Investors fail to exercise in full the Participation Right within such five (5) plus three (3) plus three (3) Business Day period, then the Company shall have One Hundred Eighty (180) calendar days thereafter to sell the New Securities with respect to which the Investors' Participation Rights hereunder were not exercised, at a price not less than, and upon general terms not more favorable than those specified in the Company Notice. If the Company has not issued and sold the New Securities within such One Hundred Eighty (180) calendar day period, then the Company shall not thereafter issue or sell any New Securities without again first offering such New Securities to the Investors pursuant to this Section 7.16. (e) SUBSEQUENT PARTICIPATION RIGHT. From and after the date of this Agreement, the Company shall not enter into any agreement with any holder or prospective holder of any securities which would allow such holder or prospective holder a participation right, right of first refusal, right of first offer or other similar right which is on terms materially more favorable to such holder or prospective holder than, or in preference to, the Participation Right granted to the Investors hereunder. 7.17 EXECUTIVE RECRUITING FIRM. The Company shall retain an executive recruiting firm, reasonably acceptable to the Investors, to conduct a search for a Senior Vice President of Development until such time as a Senior Vice President of Development is hired by the Company or a majority of the board of directors (i.e., a majority of the total number of directors then in office) approves a termination of such search. 7.18 MANAGEMENT COMPENSATION PLAN. As of the date of this Agreement, the Company entered into new employment agreements with its C.E.O., C.F.O. and Chief Scientific Officer in the form of Exhibits H-1, H-2, and H-3, respectively, each to be effective upon Closing. As of the date of this Agreement, the Company shall have granted options to the individuals and in the amounts set forth on Section 7.13 of the Company Disclosure Statement. 7.19 WAIVERS. The Company shall keep in full force and effect the agreements listed in Sections 3.11(n)(7) and 3.11(n)(8) of the Company Disclosure Schedule. 7.20 BOARD OBSERVERS. From the date of this Agreement until the Closing, a representative (who shall be acceptable to the Company in its reasonable judgment) of each of Sprout, Oxford and Venrock (each an "Observer") shall have the right to attend all meetings of the board of directors of the Company in a nonvoting observer capacity, to receive notice of such meetings and to receive the information provided by the Company to the board of directors; provided, however, that the Company reserves the right to withhold any information and to exclude any Observer from any meeting or portion thereof (so long as the Company notifies such Observer of such withholding) if access to such information or attendance at such meeting would in the good faith determination of the board of directors (a) adversely affect the attorney-client privilege between the Company and its counsel or cause the board of directors to breach its fiduciary duties, (b) result in a conflict of interest or potential conflict of interest with the Company, or (c) impair the Company's ability to enforce its rights under this Agreement in any bona fide dispute with the Observer. Each Observer agrees to hold all information received pursuant to this Section 7.20 in confidence, to enter into a reasonable confidentiality agreement with the Company, and not to use or disclose any of such information to any third party, except to the extent such information is known, or when such information becomes known, to the public (other than as a result of a breach of this sentence by any Observer) (such non-public information, "Confidential Information"); provided, however, that an Observer may disclose Confidential Information as may be required by law, after receiving written advice of counsel that such disclosure is required, provided that such Observer takes reasonable steps to minimize the extent of any such required disclosure. The Company recognizes that certain of the Observers or their Affiliates are engaged in the business of providing venture capital financing and management advice to companies in which they invest (the "Venture Investors"), and that in their business the Venture Investors may seek to invest in and/or provide advice to companies that may be competitive with the Company. Accordingly, notwithstanding anything to the contrary in this Agreement, the Company understands and agrees that nothing in this Agreement will restrict the Venture Investors from investing or participating in the management of any business or entity which competes or may compete, directly or indirectly, with the Company so long as such Venture Investor does not disclose any Confidential Information to such business or entity or help or otherwise assist such business or entity to use such information in violation hereof. The Company further agrees that, provided a Venture Investor does not disclose Confidential Information to a third-party in violation hereof, such Venture Investor shall be free to use for internal use in its business any information it has obtained or will obtain from the Company; provided, however, that any recipient of such information is similarly restricted with respect to Confidential Information; and provided, further, such Venture Investor shall not disclose any such information to an officer, director, Affiliate, employee, or significant stockholder of any business or entity that competes or may reasonably be deemed to compete, directly or indirectly, with the Company. 7.21 THIRD PARTY OFFER. During the period from the date of this Agreement until the Closing or the effective date of termination of this Agreement, if the Company intends to seek any financing or to seek any transaction not in the ordinary course of business consistent with past practice that would qualify as an Alternative Proposal but for the 20% threshold specified in Section 7.14(c) or is approached by any third party with any offer to provide such financing or transaction that the Company does not immediately and unconditionally reject (a "Third Party Offer"), the Company shall first endeavor to negotiate with the Investors, for a period not to exceed fifteen (15) Business Days, a financing or transaction comparable to the Third Party Offer. The Company and the Investors shall negotiate in good faith with respect to such financing or transaction, but nothing in this Agreement shall be construed to require the Investors to provide, on the one hand, or the Company to accept, on the other hand, any such financing or transaction; provided, however, that if the Company receives a Third Party Offer, the Company shall notify the Investors of the amount of such offer and all the other material terms of such offer and, if the Investors, within the fifteen (15) Business Day period specified above, offer to provide financing to, or enter into a transaction with, the Company in the amount, as applicable, and on terms no less favorable than those contained in the Third Party Offer, the Company shall accept the Investors' offer, if it accepts any offer. For the avoidance of doubt, the parties hereto agree that any Third Party Offer involving the right of a Person other than the Investors or their Affiliates to (i) purchase or acquire less than 20% of the business, properties or other assets or capital stock or other equity interests in the Company, whether by share issuance, equity or convertible debt financing, sale of stock or assets, merger, consolidation, other business combination, tender offer, exchange offer, recapitalization, reorganization, liquidation, dissolution, license agreement, mortgage, lease or other transaction involving the Company, any division or operating or principal business unit or the Intellectual Property of the Company, on the one hand, and any other Person, on the other hand or (ii) enter into any transaction, that if consummated, would result in any Person (or the stockholders of such Person) beneficially owning securities representing less than 20% of the total voting power of the Company (or of the surviving parent entity in such transaction) shall be deemed a Third Party Offer and not an Alternative Proposal. SECTION 8 TERMINATION 8.1 TERMINATION EVENTS. Without prejudice to other remedies which may be available to the parties by law or this Agreement, this Agreement may be terminated and the transactions contemplated hereby may be abandoned at any time prior to the Closing: (a) Mutually, by the written consent of the Company and Consent of the Investors; (b) by either the Company or Consent of the Investors by giving written notice to the other party or parties if the Closing shall not have occurred prior to June 30, 2003, unless extended by written agreement of the parties; provided that the party seeking termination pursuant to this subsection (b) is not in default or breach hereunder and provided, further, that the right to terminate this Agreement under this subsection (b) shall not be available (i) to any party whose failure to fulfill any obligation under this Agreement has been the cause of, or resulted in, the failure of the Closing to occur on or before such date or (ii) in the event that the Closing shall not have occurred as a result of a failure of any representation to be true and correct in all material respects and the party seeking termination knew of such breach prior to the date of this Agreement (such failing or knowing party being the "Delaying Party"); (c) by either the Company or Consent of the Investors by giving written notice to the other party or parties if any Governmental Entity shall have issued an injunction or other ruling prohibiting the consummation of any of the transactions contemplated by this Agreement and such injunction or other ruling shall not be subject to appeal or shall have become final and unappealable; (d) by either the Company or Consent of the Investors in the event that Stockholder Approval is not obtained at the Stockholders' Meeting; or (e) by the Company, if the Company's board of directors shall have recommended to the stockholders of the Company an Alternative Proposal; provided that, in order for the termination of this Agreement pursuant to this clause (e) to be deemed effective, the Company shall have complied with all provisions of Sections 7.4, 7.14, and 7.21. 8.2 EFFECT OF TERMINATION. In the event of any termination of this Agreement pursuant to Section 8.1, all rights and obligations of the parties hereunder shall terminate without any liability on the part of any party or its Subsidiaries and Affiliates in respect thereof; provided, however, that (A) such termination shall not relieve the Company or any Investor of any liability for any breach or non-fulfillment of, or non-compliance with, this Agreement; and (B) if the Company terminates this Agreement (i) pursuant to Section 8.1(b) and within six (6) months thereafter enters into a definitive agreement regarding an Alternative Proposal and the Investors are not a Delaying Party or (ii) pursuant to Section 8.1(e), then the Company shall pay the Investors an aggregate of Two-Hundred Fifty Thousand Dollars ($250,000) and in addition shall promptly reimburse the Investors for their reasonable, documented legal, financial, due diligence, and advisory fees and expenses; and (C) if the Company terminates this Agreement pursuant to Section 8.1(d), the Company shall promptly reimburse the Investors for their reasonable, documented legal, financial, due diligence, and advisory fees and expenses.

The party in whose favor a final judgment is rendered shall be entitled to reasonable costs and reasonable attorneys' fees. 9.4 SURVIVAL.

The provisions hereof shall inure to the benefit of, and be binding upon, the successors, assigns, heirs, executors and administrators of the parties to this Agreement. Neither the Company nor the Investors may assign, except as expressly contemplated herein, any rights, obligations or benefits under this Agreement without the prior written consent of the other party. 9.6 ENTIRE AGREEMENT.

The initial press release with respect to the execution of this Agreement shall be approved by the Company and Sprout, Oxford and Venrock on behalf of the Investors.

The Company Disclosure Schedule is qualified in its entirety by reference to specific provisions of this Agreement, and is not intended to constitute, and shall not be construed as constituting, representation or warranties of the Company except as and to the extent provided in this Agreement. Inclusion of any item in the Company Disclosure Schedule: (1) does not represent a determination by the Company that such item (i) is material nor shall it be deemed to establish a standard of materiality (except to the extent that this Agreement provides otherwise) or (ii) did not arise in the ordinary course of business (except to the extent that this Agreement provides otherwise) and (2) shall not constitute, or be deemed to be, an admission to any third party concerning such item by the Company. (b) Notwithstanding any disclosure to the contrary in the Disclosure Schedule, if the Company were deemed to have any Subsidiary, then (i) the Company's representations and warranties referencing the Company hereunder shall be deemed to be modified so that for each such representation and warranty the Company shall be deemed to have made a corresponding representation and warranty referencing such Subsidiary, and (ii) the definitions in Section 1 that make reference to the Company shall, as appropriate, be deemed to be modified to also make reference to such Subsidiary.

NO SALE OR DISPOSITION MAY BE EFFECTED WITHOUT (I) AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO, (II) AN OPINION OF COUNSEL OR OTHER EVIDENCE, REASONABLY SATISFACTORY TO THE COMPANY, THAT SUCH REGISTRATION IS NOT REQUIRED, (III) RECEIPT OF NO-ACTION LETTERS FROM THE APPROPRIATE GOVERNMENTAL AUTHORITIES, OR (IV) OTHERWISE COMPLYING WITH THE PROVISIONS OF SECTION 7 OF THIS WARRANT. RIBOZYME PHARMACEUTICALS, INC. WARRANT TO PURCHASE ____ SHARES OF COMMON STOCK Warrant No. W-___ THIS CERTIFIES THAT, for value received, ___________and its assigns are entitled to subscribe for and purchase [___________________________] shares (as adjusted pursuant to Section 4 hereof, the "SHARES") of the fully paid and nonassessable common stock, par value $0.01 per share ("COMMON STOCK"), of Ribozyme Pharmaceuticals, Inc., a Delaware corporation (the "COMPANY"), at the price of $0.42 per share (such price and such other price as shall result, from time to time, from the adjustments specified in Section 4 hereof is herein referred to as the "WARRANT PRICE"), subject to the provisions and upon the terms and conditions hereinafter set forth. As used herein, (a) the term "DATE OF GRANT" means the date of the "Closing" as defined in the Common Stock and Warrant Purchase Agreement dated as of February ___, 2003 among the Company and the investors listed on EXHIBIT A thereto (the "PURCHASE AGREEMENT"), and (b) the term "OTHER WARRANTS" means any other warrants issued by the Company in connection with the transaction with respect to which this Warrant was issued, and any warrant issued upon transfer or partial exercise of this Warrant. The term "WARRANT" as used herein shall be deemed to include Other Warrants unless the context clearly requires otherwise. 1. TERM. The purchase right represented by this Warrant is exercisable, in whole or in part, at any time and from time to time from the Date of Grant through five (5) years after the Date of Grant. 2. METHOD OF EXERCISE; PAYMENT; ISSUANCE OF NEW WARRANT. Subject to Section 1 hereof, the purchase right represented by this Warrant may be exercised by the holder hereof, in whole or in part and from time to time, at the election of the holder hereof, by (a) the surrender of this Warrant (with the notice of exercise substantially in the form attached hereto as EXHIBIT A-1 duly completed and executed) at the principal office of the Company and by the payment to the Company, by certified or bank check, or by wire transfer to an account designated by the Company (a "WIRE TRANSFER") of an amount equal to the then applicable Warrant Price multiplied by the number of Shares then being purchased, or (b) if in connection with a registered public offering of the Company's securities, the surrender of this Warrant (with the notice of exercise form attached hereto as EXHIBIT A-2 duly completed and executed) at the principal office of the Company together with notice of arrangements reasonably satisfactory to the Company for payment to the Company either by certified or bank check or by Wire Transfer from the proceeds of the sale of shares to be sold by the holder in such public offering of an amount equal to the then applicable Warrant Price per share multiplied by the number of Shares then being purchased, or (c) exercise of the "net issuance" right provided for in Section 10.2 hereof. The person or persons in whose name(s) any certificate(s) representing the Shares shall be issuable upon exercise of this Warrant shall be deemed to have become the holder(s) of record of, and shall be treated for all purposes as the record holder(s) of, the shares represented thereby (and such shares shall be deemed to have been issued) immediately prior to the close of business on the date or dates upon which this Warrant is exercised. In the event of any exercise of the rights represented by this Warrant, certificates for the shares of stock so purchased shall be delivered to the holder hereof as soon as practicable and, if requested by the holder of this Warrant, the Company shall cause its transfer agent to deliver the certificate representing Shares issued upon exercise of this Warrant to a broker or other person (as directed by the holder exercising this Warrant) within the time period required to settle any trade made by the holder after exercise of this Warrant. 3. STOCK FULLY PAID; RESERVATION OF SHARES. All Shares that may be issued upon the exercise of the rights represented by this Warrant will, upon issuance pursuant to the terms and conditions herein, be fully paid and nonassessable, and free from all taxes, liens and charges with respect to the issue thereof. During the period within which the rights represented by this Warrant may be exercised, the Company will at all times have authorized, and reserved for the purpose of the issue upon exercise of the purchase rights evidenced by this Warrant, a sufficient number of shares of its Common Stock to provide for the exercise of the rights represented by this Warrant. 4. ADJUSTMENT OF WARRANT PRICE AND NUMBER OF SHARES. The number and kind of securities purchasable upon the exercise of this Warrant and the Warrant Price shall be subject to adjustment from time to time upon the occurrence of certain events, as follows: (a) RECLASSIFICATION OR MERGER. In case of any reclassification or change of securities of the class issuable upon exercise of this Warrant (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination), or in case of any merger of the Company with or into another corporation (other than a merger with another corporation in which the Company is the acquiring and the surviving corporation and which does not result in any reclassification or change of outstanding securities issuable upon exercise of this Warrant), or in case of any sale of all or substantially all of the assets of the Company, the Company, or such successor or purchasing corporation, as the case may be, shall duly execute and deliver to the holder of this Warrant a new Warrant (in form and substance satisfactory to the holder of this Warrant), or the Company shall make appropriate provision without the issuance of a new Warrant, so that the holder of this Warrant shall have the right to receive upon exercise of this Warrant, at a total purchase price not to exceed that payable upon the exercise of the unexercised portion of this Warrant, and in lieu of the shares of Common Stock theretofore issuable upon exercise of this Warrant, the kind and amount of shares of stock, other securities, money and property receivable upon such reclassification, change or merger by a holder of the number of shares of Common Stock then purchasable under this Warrant. Such new Warrant shall provide for adjustments that shall be as nearly equivalent as may be practicable to the adjustments provided for in this Section 4. The provisions of this subparagraph (a) shall similarly apply to successive reclassifications, changes, mergers and transfers. (b) SUBDIVISION OR COMBINATION OF SHARES. If the Company at any time while this Warrant remains outstanding and unexpired shall subdivide or combine its outstanding shares of Common Stock, the Warrant Price shall be proportionately decreased and the number of Shares issuable hereunder shall be proportionately increased in the case of a subdivision or the Warrant Price shall be proportionately increased and the number of Shares issuable hereunder shall be proportionately decreased in the case of a combination. (c) STOCK DIVIDENDS AND OTHER DISTRIBUTIONS. If the Company at any time while this Warrant is outstanding and unexpired shall pay a dividend or make a distribution to all of its stockholders with respect to its Common Stock payable in Common Stock, then the Warrant Price shall be adjusted, from and after the date of determination of stockholders entitled to receive such dividend or distribution, to that price determined by multiplying the Warrant Price in effect immediately prior to such date of determination by a fraction (A) the numerator of which shall be the total number of shares of Common Stock outstanding immediately prior to such dividend or distribution, and (B) the denominator of which shall be the total number of shares of Common Stock outstanding immediately after such dividend or distribution. (d) ADJUSTMENT OF NUMBER OF SHARES. Upon each adjustment in the Warrant Price, the number of Shares purchasable hereunder shall be adjusted, to the nearest whole share, to the product obtained by multiplying the number of Shares purchasable immediately prior to such adjustment in the Warrant Price by a fraction, the numerator of which shall be the Warrant Price immediately prior to such adjustment and the denominator of which shall be the Warrant Price immediately thereafter. 5. NOTICE OF ADJUSTMENTS. Whenever the Warrant Price or the number of Shares purchasable hereunder shall be adjusted pursuant to Section 4 hereof, the Company shall make a certificate signed by its chief executive officer, chief financial officer or any vice president setting forth, in reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated, and the Warrant Price and the number of Shares purchasable hereunder after giving effect to such adjustment, and shall cause copies of such certificate to be mailed (without regard to Section 13 hereof, by first class mail, postage prepaid) to the holder of this Warrant at such holder's last known address. 6. FRACTIONAL SHARES. No fractional shares of Common Stock will be issued in connection with any exercise hereunder, but in lieu of such fractional shares the Company shall make a cash payment therefor based on the fair market value of the Common Stock on the date of exercise as reasonably determined in good faith by the Company's Board of Directors. 7. COMPLIANCE WITH SECURITIES ACT; DISPOSITION OF WARRANT OR SHARES OF COMMON STOCK. (a) COMPLIANCE WITH SECURITIES ACT. The holder of this Warrant, by acceptance hereof, agrees that this Warrant, and the Shares to be issued upon exercise hereof are being acquired for investment and that such holder will not offer, sell or otherwise dispose of this Warrant, or any Shares except under circumstances which will not result in a violation of the Securities Act of 1933, as amended (the "ACT") or any applicable state securities laws. Upon exercise of this Warrant, unless the Shares being acquired are registered under the Act and any applicable state securities laws or an exemption from such registration is available, the holder hereof shall confirm in writing that the Shares so purchased are being acquired for investment and not with a view toward distribution or resale in violation of the Act and shall confirm such other matters related thereto as may be reasonably requested by the Company. This Warrant and all Shares issued upon exercise of this Warrant (unless registered under the Act and any applicable state securities laws) shall be stamped or imprinted with a legend in substantially the following form: "THE SECURITIES EVIDENCED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS. NO SALE OR DISPOSITION MAY BE EFFECTED WITHOUT (I) AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO, (II) AN OPINION OF COUNSEL OR OTHER EVIDENCE, REASONABLY SATISFACTORY TO THE COMPANY, THAT SUCH REGISTRATION IS NOT REQUIRED, (III) RECEIPT OF NO-ACTION LETTERS FROM THE APPROPRIATE GOVERNMENTAL AUTHORITIES, OR (IV) OTHERWISE COMPLYING WITH THE PROVISIONS OF SECTION 7 OF THE WARRANT UNDER WHICH THESE SECURITIES WERE ISSUED, DIRECTLY OR INDIRECTLY." Said legend shall be removed by the Company, upon the request of a holder, at such time as the restrictions on the transfer of the applicable security shall have terminated. In addition, in connection with the issuance of this Warrant, the holder specifically represents to the Company by acceptance of this Warrant as follows: (1) The holder is aware of the Company's business affairs and financial condition, and has acquired information about the Company sufficient to reach an informed and knowledgeable decision to acquire this Warrant. The holder is acquiring this Warrant for its own account for investment purposes only and not with a view to, or for the resale in connection with, any "distribution" thereof in violation of the Act. (2) The holder understands that this Warrant has not been registered under the Act in reliance upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of the holder's investment intent as expressed herein. (3) The holder further understands that this Warrant must be held indefinitely unless subsequently registered under the Act and qualified under any applicable state securities laws, or unless exemptions from registration and qualification are otherwise available. The holder is aware of the provisions of Rule 144, promulgated under the Act. (4) The holder is an "accredited investor" as such term is defined in Rule 501 of Regulation D promulgated under the Act. (b) DISPOSITION OF WARRANT OR SHARES. With respect to any offer, sale or other disposition of this Warrant or any Shares acquired pursuant to the exercise of this Warrant prior to registration of such Warrant or Shares, the holder hereof agrees to give written notice to the Company prior thereto, describing briefly the manner thereof, together with a written opinion of such holder's counsel, or other evidence satisfactory to the Company, to the effect that such offer, sale or other disposition may be effected without registration or qualification (under the Act as then in effect or any federal or state securities law then in effect) of this Warrant or the Shares and indicating whether or not under the Act certificates for this Warrant or the Shares to be sold or otherwise disposed of require any restrictive legend as to applicable restrictions on transferability in order to ensure compliance with such law. Upon receiving such written notice and reasonably satisfactory opinion or other evidence, the Company, as promptly as practicable but no later than fifteen (15) days after receipt of the written notice, shall notify such holder that such holder may sell or otherwise dispose of this Warrant or such Shares, all in accordance with the terms of the notice delivered to the Company. If a determination has been made pursuant to this Section 7(b) that the opinion of counsel for the holder or other evidence is not reasonably satisfactory to the Company, the Company shall so notify the holder promptly with details thereof after such determination has been made. Notwithstanding the foregoing, this Warrant or such Shares may, as to such federal laws, be offered, sold or otherwise disposed of in accordance with Rule 144 or 144A under the Act, provided that the Company shall have been furnished with such information as the Company may reasonably request to provide a reasonable assurance that the provisions of Rule 144 or 144A have been satisfied. Each certificate representing this Warrant or the Shares thus transferred (except a transfer pursuant to Rule 144) shall bear a legend as to the applicable restrictions on transferability in order to ensure compliance with such laws, unless in the aforesaid opinion of counsel for the holder, such legend is not required in order to ensure compliance with such laws. The Company may issue stop transfer instructions to its transfer agent in connection with such restrictions. (c) APPLICABILITY OF RESTRICTIONS. Neither any restrictions of any legend described in this Warrant nor the requirements of Section 7(b) above shall apply to any transfer or grant of a security interest in, this Warrant (or the shares of Common Stock obtainable upon exercise thereof) or any part hereof (i) to a partner of the holder if the holder is a partnership or to a member of the holder if the holder is a limited liability company, (ii) to a partnership of which the holder is a partner or a limited liability company of which the holder is a member, or (iii) to any affiliate of the holder if the holder is a corporation; provided, however, in any such transfer, if applicable, the transferee shall on the Company's request agree in writing to be bound by the terms of this Warrant as if an original holder hereof. 8. RIGHTS AS SHAREHOLDERS. No holder of this Warrant, as such, shall be entitled to vote or receive dividends or be deemed the holder of Common Stock or any other securities which may at any time be issuable on the exercise hereof for any purpose, nor shall anything contained herein be construed to confer upon the holder of this Warrant, as such, any of the rights of a shareholder of the Company or any right to vote for the election of directors or upon any matter submitted to shareholders at any meeting thereof, or to receive notice of meetings, or to receive dividends or subscription rights or otherwise until this Warrant shall have been exercised and the Shares purchasable upon the exercise hereof shall have become deliverable, as provided herein. 9. REGISTRATION RIGHTS. The Company grants registration rights to the holder of this Warrant for any shares of Common Stock of the Company obtained upon exercise hereof as set forth in the Purchase Agreement. 10. ADDITIONAL RIGHTS. 10.1. MERGERS. The Company shall provide the holder of this Warrant with at least twenty (20) days' written notice prior to the closing thereof of the terms and conditions of any of the following transactions: (i) the sale, lease, exchange, conveyance or other disposition of all or substantially all of the Company's property or business, or (ii) its merger into or consolidation with any other corporation (other than a wholly-owned subsidiary of the Company), or (iii) any transaction (including a merger or other reorganization) or series of related transactions, in which more than 50% of the voting power of the Company is disposed of. 10.2. RIGHT TO CONVERT WARRANT INTO STOCK: NET ISSUANCE. (a) RIGHT TO CONVERT. In addition to and without limiting the rights of the holder under the terms of this Warrant, the holder shall have the right to convert this Warrant or any portion thereof (the "CONVERSION RIGHT") into shares of Common Stock as provided in this Section 10.2 at any time or from time to time during the term of this Warrant. Upon exercise of the Conversion Right with respect to a particular number of shares subject to this Warrant (the "CONVERTED WARRANT SHARES"), the Company shall deliver to the holder (without payment by the holder of any exercise price or any cash or other consideration) that number of shares of fully paid and nonassessable Common Stock as is determined according to the following formula: X = B - A ----- Y Where: X = the number of shares of Common Stock that may be issued to the holder. Y = the fair market value of one share of Common Stock. A = the aggregate Warrant Price of the specified number of Converted Warrant Shares immediately prior to the exercise of the Conversion Right (i.e., the number of Converted Warrant Shares multiplied by the Warrant Price). B = the aggregate fair market value of the specified number of Converted Warrant Shares (i.e., the number of Converted Warrant Shares multiplied by the fair market value of one Converted Warrant Shares). No fractional shares shall be issuable upon exercise of the Conversion Right, and, if the number of shares to be issued determined in accordance with the foregoing formula is other than a whole number, the Company shall pay to the holder an amount in cash equal to the fair market value of the resulting fractional share on the Conversion Date (as hereinafter defined). For purposes of Section 9 of this Warrant, shares issued pursuant to the Conversion Right shall be treated as if they were issued upon the exercise of this Warrant. (b) METHOD OF EXERCISE. The Conversion Right may be exercised by the holder by the surrender of this Warrant at the principal office of the Company together with a written statement (which may be in the form of EXHIBIT A-1 or EXHIBIT A-2 hereto) specifying that the holder thereby intends to exercise the Conversion Right and indicating the number of shares subject to this Warrant which are being surrendered (referred to in Section 10.2(a) hereof as the Converted Warrant Shares) in exercise of the Conversion Right. Such conversion shall be effective upon receipt by the Company of this Warrant together with the aforesaid written statement, or on such later date as is specified therein (the "CONVERSION DATE"), and, at the election of the holder hereof, may be made contingent upon the closing of the sale of the Company's Common Stock to the public in a public offering pursuant to a registration statement under the Act (a "PUBLIC OFFERING"). Certificates for the shares issuable upon exercise of the Conversion Right and, if applicable, a new warrant evidencing the balance of the shares remaining subject to this Warrant, shall be issued as of the Conversion Date and shall be delivered to the holder within thirty (30) days following the Conversion Date. (c) DETERMINATION OF FAIR MARKET VALUE. For purposes of this Section 10.2, "fair market value" of a share of Common Stock as of a particular date (the "DETERMINATION DATE") shall mean: (i) If the Conversion Right is exercised in connection with and contingent upon a Public Offering, and if the Company's Registration Statement relating to such Public Offering ("REGISTRATION STATEMENT") has been declared effective by the Securities and Exchange Commission, then the initial "Price to Public" specified in the final prospectus with respect to such offering. (ii) If the Conversion Right is not exercised in connection with and contingent upon a Public Offering, then as follows: (A) If traded on a securities exchange, the fair market value of the Common Stock shall be deemed to be the average of the closing prices of the Common Stock on such exchange over the five trading days immediately prior to the Determination Date; (B) If traded on the Nasdaq Stock Market or other over-the-counter system, the fair market value of the Common Stock shall be deemed to be the average of the closing bid prices of the Common Stock over the five trading days immediately prior to the Determination Date; and (C) If there is no public market for the Common Stock, then fair market value shall be reasonably determined by the Company's Board of Directors. If closing prices or closing bid prices are no longer reported by a securities exchange or other trading system, the closing price or closing bid price shall be that which is reported by such securities exchange or other trading system at 4:00 p.m. New York City time on the applicable trading day. 11. REPRESENTATIONS AND WARRANTIES. The Company represents and warrants to the holder of this Warrant as follows: (a) This Warrant has been duly authorized and executed by the Company and is a valid and binding obligation of the Company enforceable in accordance with its terms, subject to laws of general application relating to bankruptcy, insolvency, moratorium, reorganization and the relief of debtors and the rules of law or principles at equity governing specific performance, injunctive relief and other equitable remedies (regardless of whether enforcement is sought in equity or at law); (b) The Shares have been duly authorized and reserved for issuance by the Company and, when issued in accordance with the terms hereof will be validly issued, fully paid and non-assessable; (c) The execution and delivery of this Warrant are not, and the issuance of the Shares upon exercise of this Warrant in accordance with the terms hereof will not be, inconsistent with the Company's certificate of incorporation or by-laws, do not and will not contravene any law, governmental rule or regulation, judgment or order applicable to the Company, [and do not and will not conflict with or contravene any provision of, or constitute a default under, any material indenture, mortgage, contract or other instrument of which the Company is a party or by which it is bound or require the consent or approval of, the giving of notice to, the registration or filing with or the taking of any action in respect of or by, any Federal, state or local government authority or agency or other person,] except for the filing of notices pursuant to federal and state securities laws, which filings will be effected by the time required thereby; and (d) There are no actions, suits, audits, investigations or proceedings pending or, to the knowledge of the Company, threatened against the Company in any court or before any governmental commission, board or authority which, if adversely determined, will have a material adverse effect on the ability of the Company to perform its obligations under this Warrant. 12. MODIFICATION AND WAIVER. This Warrant and any provision hereof may be changed, waived, discharged or terminated only by an instrument in writing signed by the party against which enforcement of the same is sought. 13. NOTICES. Any notice, request, communication or other document required or permitted to be given or delivered to the holder hereof or the Company shall be delivered, or shall be sent by certified or registered mail, postage prepaid, to each such holder at its address as shown on the books of the Company or to the Company at the address indicated therefor on the signature page of this Warrant. 14. BINDING EFFECT ON SUCCESSORS. This Warrant shall be binding upon any corporation succeeding the Company by merger, consolidation or acquisition of all or substantially all of the Company's assets, and all of the obligations of the Company relating to the Shares issuable upon the exercise or conversion of this Warrant shall survive the exercise, conversion and termination of this Warrant and all of the covenants and agreements of the Company shall inure to the benefit of the successors and assigns of the holder hereof. 15. LOST WARRANTS OR STOCK CERTIFICATES. The Company covenants to the holder hereof that, upon receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant or any stock certificate and, in the case of any such loss, theft or destruction, upon receipt of an indemnity reasonably satisfactory to the Company, or in the case of any such mutilation upon surrender and cancellation of such Warrant or stock certificate, the Company will make and deliver a new Warrant or stock certificate, of like tenor, in lieu of the lost, stolen, destroyed or mutilated Warrant or stock certificate. 16. DESCRIPTIVE HEADINGS. The descriptive headings of the several paragraphs of this Warrant are inserted for convenience only and do not constitute a part of this Warrant. The language in this Warrant shall be construed as to its fair meaning without regard to which party drafted this Warrant. 17. GOVERNING LAW. This Warrant shall be construed and enforced in accordance with, and the rights of the parties shall be governed by, the laws of the State of Delaware. 18. SURVIVAL OF REPRESENTATIONS, WARRANTIES AND AGREEMENTS. All representations and warranties of the Company and the holder hereof contained herein shall survive the Date of Grant, the exercise or conversion of this Warrant (or any part hereof) or the termination or expiration of rights hereunder. All agreements of the Company and the holder hereof contained herein shall survive indefinitely until, by their respective terms, they are no longer operative. 19. REMEDIES. In case any one or more of the covenants and agreements contained in this Warrant shall have been breached, the holders hereof (in the case of a breach by the Company), or the Company (in the case of a breach by a holder), may proceed to protect and enforce their or its rights either by suit in equity and/or by action at law, including, but not limited to, an action for damages as a result of any such breach and/or an action for specific performance of any such covenant or agreement contained in this Warrant. 20. NO IMPAIRMENT OF RIGHTS. The Company will not, by amendment of its certificate of incorporation or through any other means, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such action as may be necessary or appropriate in order to protect the rights of the holder of this Warrant against impairment. 21. SEVERABILITY. Whenever possible, each provision of this Warrant shall be interpreted in such a manner as to be valid, legal and enforceable under all applicable laws and regulations. If, however, any provision of this Warrant shall be invalid, illegal or unenforceable under any such law or regulation in any jurisdiction, it shall, as to such jurisdiction, be deemed modified to conform to the minimum requirements of such law or regulation, or, if for any reason it is not deemed to be so modified, it shall be invalid, illegal or unenforceable only to the extent of such invalidity, illegality or limitation on enforceability without affecting the remaining provisions of this Warrant or the validity, legality or enforceability of such provision in any other jurisdiction. [Remainder of page intentionally left blank] 22. ENTIRE AGREEMENT; MODIFICATION.

We have disclosed or at all relevant times intended and intend to disclose to the United States Patent and Trademark Office any references known by us to be material to the patentability of the claimed inventions of the United States patent applications of the Company being prosecuted by us and listed on Exhibit A in a manner that satisfies 37 C.F.R. ss. 1.56. b. All patents and applications that are being or have been prosecuted by us relating to RNA interference (RNAi) processes mediated by small interfering nucleic acid (siNA, including siRNA) molecules (collectively, RNAi technology), as identified on Exhibit C, have been assigned to the Company, or the inventors on such patents or patent applications have been represented to us as being employees of the Company under an obligation to assign their rights in such patents or patent applications to the Company. To the best of our knowledge, all of the remaining patents, trademarks, and applications being prosecuted by us and listed on Exhibit A and Exhibit B either have been assigned or licensed to the Company, or one or more inventors on such patents or patent applications are under an obligation to assign their rights in such patents or patent applications to the Company or to the Company's licensor. c. But for the exceptions noted below, we have not, within the last one-year period, received any written notice from a third party challenging ownership, validity, or enforceability of any patent or trademark of the Company. Moreover, but for the exceptions noted below, we have not, within the last one-year period, received any information from the Company regarding any written notice from a third party challenging ownership, validity, or enforceability of any patent or trademark of the Company. As to the subject matter of the siNA applications identified in Exhibit C, and but for the exceptions noted below, we have not received and we are not aware of the Company having received any notice from any third party charging patent infringement or challenging the ownership, validity, or enforceability of the Company's position. Exceptions: (i) a potential interference proceeding in the U.S. Patent and Trademark Office against Hybridon; (ii) a pending re-examination proceeding filed by a third party in the U.S. Patent and Trademark Office against one of the Company's Inbound License Agreement Patents; (iii) an opposition proceeding in the European Patent Office against one of the Company's Inbound License Agreement Patents; (iv) a pending opposition proceeding filed by the Company in the European Patent Office against a third-party patent application; (v) a possible opposition proceeding being contemplated by the Company in the European Patent Office against a third-party patent application; and (vi) pending opposition proceedings have been filed by two companies, Klinge Pharma and Sofex, against the Company's application to obtain trademark registration in the European Community for the mark, "Ribozyme Pharmaceuticals, Inc." We understand that the Company has disclosed the exceptions noted above. d. We have not, within the last one-year period, received any written notice threatening litigation against the Company for infringement with respect to any patent, trademark, or copyright, or threatening litigation for unfair competition or misappropriation of trade secret. Moreover, we have not, within the last one-year period, received any information from the Company regarding any written notice, received by the Company, threatening litigation against the Company for infringement with respect to any patent, trademark, or copyright, or threatening litigation for unfair competition or misappropriation of trade secret. However, the Company has advised us of prior communications with Anjinomoto (Japan) and Gene Shears (Australia), which situations have been disclosed by the Company to our understanding, and we note the general exceptions listed above. e. We do not represent the Company in connection with pending litigation against the Company concerning patent infringement, trademark infringement, copyright infringement, unfair competition, or misappropriation of trade secret. Moreover, we are not aware of pending litigation against the Company concerning patent infringement, trademark infringement, copyright infringement, unfair competition, or misappropriation of trade secret. However we note the general exceptions listed above. f. To the best of our knowledge, based on the information given to us to date by the Company about the Company's processes and the conduct of its business, we are not presently aware of any situation in which the Company's processes or the conduct of its business are violating any patents, trademarks, copyrights, trade secrets, or other proprietary rights of a third party. To the extent we have considered any specific aspect of the Company's processes or its business in relation to a specific patent, trademark, or copyright of a third party, we have not issued any opinion that is adverse to the Company and would, in our judgment, materially and adversely impact the Company's business. Specifically as to RNAi technology, we previously reviewed the published patent applications identified in Exhibit D; under U.S. law, we believe the claims presented in these published patent applications did not literally claim a product that completely lacks any naturally occurring ribonucleotide. We also note the general exceptions listed above. g. We are not aware of any outstanding order, judgment, decree, or stipulation issued by a court or agency of any United States governmental unit that materially restricts the use, sale, transfer, assignment or licensing of the patent or trademark rights or that materially restricts the current business activities of the Company. The Company has not advised us as to any outstanding order, judgment, decree, or stipulation issued by a court or agency of any United States governmental unit that materially restricts the use, sale, transfer, assignment or licensing of the patent or trademark rights or that materially restricts the current business activities of the Company. h. To our knowledge, the Company has communicated with numerous organizations, directly or indirectly, regarding a potential license for those organizations under certain patent rights of the Company. The Company has also previously communicated with a third party company regarding possible infringement of one of the Company's trademarks. To our knowledge, the Company has brought no legal action for patent or trademark infringement against any such organization within the past year. i. We note that certain patents, trademarks, and applications identified in Exhibits A and B were handled in whole or in part by the Company's prior law firms, and we have limited knowledge with respect to such matters. In addition, we note that we have been instructed by the Company to abandon certain patents and patent applications that may not pertain to the Company's future focus of operation, and Exhibits A and B may not reflect these instructions in their entirety. j. We note that we have prepared this letter at the request of the Company in the belief and understanding that a community of interests exists between your clients and the Company. Be advised that, by permitting us to respond as set forth herein, the Company does not waive and does not intend to waive the attorney-client privilege with respect to any information which the Company has furnished to us. Moreover, please be advised that our comments to you should not be construed in any way to constitute a waiver of the protection of the attorney-client privilege with respect to any of our work for the Company. k. This letter and the information contained herein are being provided to you solely in relation to the Common Stock and Warrant Purchase Agreement (January 2003), and this letter is not to be quoted in whole or in part or otherwise referred to in any documents or notes, nor is it to be filed with any governmental agency or provided to other person without the prior written consent of our firm and the Company. l. We are the Company's U.S. counsel, and we represent only the Company in this matter. Third parties should obtain an opinion of their own counsel before making business or investment decisions in relation to this matter. EXHIBIT E FORM OF NON-COMPETITION and NON-SOLICITATION AGREEMENT This Non-Competition and Non-Solicitation Agreement (this "AGREEMENT") is entered into as of February ____, 2003, by and among Ribozyme Pharmaceuticals, Inc., a Delaware corporation (the "COMPANY") and _______________, an individual ("EMPLOYEE"). RECITALS The Company is engaged or proposes to engage in the business of researching, developing, manufacturing, licensing, selling, and distributing therapeutics and diagnostic technologies using nucleotides and oligonucleotides (such business being collectively referred to herein as the "BUSINESS"). From and after the closing of the transactions contemplated by the Purchase Agreement (as defined below), the Company proposes that its principal business activities shall relate to the research, development, manufacture, license, sale and distribution of therapeutic products using siRNA technology (hereinafter, "siRNA TECHNOLOGY"). During the Non-Competition Period (as hereinafter defined), the Company may, in addition to or in substitution for siRNA Technology, have additional platform technologies as its principal business activity or activities, including without limitation programs [USING SUCH PLATFORM TECHNOLOGIES] [PRECEDING BRACKETED PHRASE TO BE DELETED FOR HOWARD, MARVIN AND NASSIM] in therapeutic areas where the Company has advanced a product into pre-clinical toxicology or later stages of development (the "FIELD OF INTEREST"). For example, the current Field of Interest would include without limitation the viruses HBV and HCV and the therapeutic gene target VEGF-Receptor R-1, which are within the scope of the Company's current principal business activities, but other therapeutic areas, such as anti-viral therapeutic products and specific cancer therapeutics, would exceed the scope of activities covered by the current Field of Interest. Employee is one of the Company's key employees, an executive officer of the Company, and a member of the Company's management team. Employee acknowledges that he has detailed knowledge of the Intellectual Property and other confidential and proprietary information of the Company. Pursuant to the Common Stock and Warrant Purchase Agreement dated as of February ___, 2003 by and among the Company and the Investors listed on Exhibit A thereto (the "PURCHASE AGREEMENT"), on the terms and subject to the conditions set forth therein, the Company will issue securities to the Investors. Capitalized terms used herein shall have the meanings set forth herein or, if not defined herein, shall have the meanings ascribed to them in the Purchase Agreement. Employee has considered the effects of this Agreement, consider them reasonable and, in order to induce the Investors to enter into the Purchase Agreement and to enter into or consent to the transactions contemplated thereby (including without limitation the Employment Agreement between the Employee and the Company dated as of the date hereof (the "EMPLOYMENT AGREEMENT"), which agreement would otherwise be prohibited by the terms of the Purchase Agreement), and in order to obtain the privileges, protections, and benefits of the Employment Agreement, Employee has agreed to enter into this Agreement. NOW, THEREFORE, in consideration of the premises and the mutual covenants and agreements hereinafter set forth, Employee and the Company, intending to be legally bound, hereby agree as follows: ARTICLE 1 NON-COMPETITION 1.1 NON-COMPETITION. As an inducement for the Investors to enter into the Purchase Agreement and to enter into or consent to the transactions contemplated thereby, and in order to obtain the privileges, protections, and benefits of the Employment Agreement, Employee agrees that from and after the effective date of the Purchase Agreement (the "EFFECTIVE DATE") and until two and one-half (2 1/2) years thereafter (the "NON-COMPETITION PERIOD"); (a) Employee shall not, anywhere in the United States, engage, without the express prior written consent of the Company, in any business or activity in direct competition with Company in the then current Field of Interest, whether as an employee, consultant, partner, principal, agent, representative, equity holder or in any other individual, corporate or representative capacity (without limitation by specific enumeration of the foregoing), or render any services or provide any advice to any business, activity or Person in direct competition with the Company in the then current Field of Interest (a "COMPETING BUSINESS"). (b) Employee shall not, anywhere in Colorado, engage, without the express prior written consent of the Company, in any business or activity in direct competition with the Company in the then current Field of Interest, whether as an employee, consultant, partner, principal, agent, representative, equity holder or in any other individual, corporate or representative capacity (without limitation by specific enumeration of the foregoing), or render any services or provide any advice to any Competing Business. (c) Employee shall not, in any of the counties in the State of Colorado, engage, without the express prior written consent of the Company, in any business or activity in direct competition with the Company in the then current Field of Interest, whether as an employee, consultant, partner, principal, agent, representative, equity holder or in any other individual, corporate or representative capacity (without limitation by specific enumeration of the foregoing), or render any services or provide any advice to any Competing Business. 1.2 LIMITATION ON PROHIBITED ACTIVITIES. Notwithstanding anything to the contrary contained in this Agreement, if the Employee's employment with the Company terminates for any reason prior to the end of the Non-Competition Period, Employee may thereafter engage, without the consent of the Company, in any business or activity, whether as an employee, consultant, partner, principal, agent, representative, equity holder or in any other individual, corporate or representative capacity (without limitation by specific enumeration of the foregoing) for a Person that is engaged in the then current Field of Interest at the time of termination of Employee's employment with the Company, so long as (i) the principal business activity of such Person is not in such Field of Interest and (ii) Employee does not personally engage or provide counsel, advice, or direction in any activities that are within such Field of Interest for such Person. For the avoidance of doubt, Employee may become a senior executive for a Person that is engaged in such Field of Interest and may have employees reporting to him that are engaged in such Field of Interest, so long as Employee does not personally engage directly or directly provide counsel, advice or direction in any activities that are within such Field of Interest. 1.3 PUBLICLY TRADED SECURITIES. Notwithstanding the foregoing, Employee may own, directly or indirectly, up to one percent (1%) of any class of "publicly traded securities" of any Person which owns or operates a business that is a Competing Business. For the purposes of this SECTION 1.3, "publicly traded securities" shall mean securities that are traded on a national securities exchange or listed on the Nasdaq National Market. 1.4 NO INTERFERENCE WITH THE BUSINESS; NON-SOLICITATION. As an inducement for the Investors to enter into the Purchase Agreement, Employee agrees that, during the Non-Competition Period, Employee shall not for any reason intentionally or knowingly or willfully (a) with respect to the Business, solicit or divert any business, clients, customers, or partners made known to Employee during his employment with the Company away from the Company, (b) induce customers, clients, partners, suppliers, agents or other Persons under contract or otherwise associated or doing business with the Company who are made known to Employee during his employment with the Company to reduce or alter any such association or business with the Company, and/or (c) solicit any Person in the employment of the Company to (i) terminate such employment, and/or (ii) accept employment, or enter into any consulting arrangement, with any Person other than the Company. ARTICLE 2 REMEDIES 2.1 REMEDIES. The parties to this Agreement agree that (i) if Employee materially breaches ARTICLE 1 of this Agreement, the damage to the Company may be substantial, although difficult to ascertain, and money damages will not afford the Company an adequate remedy, and (ii) if Employee is in breach of any provision of this Agreement, or threatens a breach of this Agreement, the Company shall be entitled, in addition to all other rights and remedies as may be provided by law, to seek specific performance and injunctive and other equitable relief from any court of competent jurisdiction to prevent or restrain a breach of any provision of this Agreement. ARTICLE 3 TERM AND TERMINATION 3.1 TERM. This Agreement shall commence as of the Effective Date, and shall terminate at the end of the Non-Competition Period; provided, that this Agreement shall terminate and be of no force or effect in the event that the transactions contemplated by the Purchase Agreement are not consummated for any reason. ARTICLE 4 MISCELLANEOUS 4.1 ENTIRE AGREEMENT; AMENDMENTS AND WAIVERS; SEVERAL AGREEMENTS. This Agreement contains the entire agreement of the parties with respect to the subject matter hereof and supersedes all prior agreements, written or oral, with respect thereto. This Agreement may be amended or modified and the terms and conditions hereof may be waived, only by a written instrument signed by each of the parties or, in the case of waiver, by the party waiving compliance. No delay on the part of either party in exercising any right, power or privilege hereunder shall operate as a waiver thereof, nor shall any waiver on the part of either party of any right, power or privilege hereunder, nor any single or partial exercise of any right, power or privilege hereunder, preclude any other or further exercise thereof or the exercise of any other right, power or privilege hereunder. The rights and remedies provided herein are cumulative and are not exclusive of any rights or remedies that either party may otherwise have at law or in equity. In addition to this Agreement between the Company and Employee, the Company has entered into a similar agreement with other key employees of the Company. It is expressly agreed that this Agreement and the obligations of the parties hereunder are to be construed separately from any similar agreements with any other employee of the Company and a breach of a similar agreement by any other employee of the Company shall not constitute a breach of this Agreement. No waiver by the Company of any term or condition of this Agreement with respect to Employee, in any one or more instances, shall be deemed to be or construed as a waiver of the same or any other term or condition of any other agreement with respect to any other employee of the Company or any other Person. 4.2 NOTICES. All notices, requests and other communications hereunder must be in writing and will be deemed to have been duly given only if delivered personally against written receipt or by facsimile transmission against facsimile confirmation or dispatched by nationally recognized overnight courier prepaid, to the respective parties at the following addresses or facsimile numbers: If to the Company: Ribozyme Pharmaceuticals, Inc. 2950 Wilderness Place Boulder, CO 80301 Attn: General Counsel Fax: (303) 449-6995 If to Employee: To the address or facsimile number for notice set forth on the last page hereof. All such notices, requests and other communications will (a) if delivered personally to the address as provided in this section, be deemed given upon delivery, (b) if delivered by facsimile transmission to the facsimile number as provided for in this section, be deemed given upon facsimile confirmation, and (c) if delivered by overnight courier to the address as provided in this section, be deemed given on the earlier of the first Business Day following the date deposited with such overnight courier with the requisite payment and instructions to effect delivery on the next business day or upon receipt (in each case regardless of whether such notice, request or other communication is received by any other Person to whom a copy of such notice is to be delivered pursuant to this section). Any party from time to time may change its address, facsimile number or other information for the purpose of notices to that party by giving notice specifying such change to the other parties hereto. 4.3 GOVERNING LAW. This Agreement shall be governed by and construed in accordance with the internal laws of the State of Colorado, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of Colorado or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Colorado. 4.4 PURCHASE AGREEMENT. In the event the Purchase Agreement is not consummated or is terminated for any reason (other than a breach of this Agreement) in accordance with its terms, this Agreement shall be null and void. 4.5 SEVERABILITY. To the extent any provision of this Agreement shall be determined to be unlawful or otherwise unenforceable, in whole or in part, such determination shall not affect the validity of the remainder of this Agreement, and this Agreement shall be reformed to the extent necessary to carry out its provisions to the greatest extent possible. In the absence of such reformation, such part of such provision shall be considered deleted from this Agreement and the remainder of such provision and of this Agreement shall be unaffected and shall continue in full force and effect. In furtherance and not in limitation of the foregoing, should the duration or geographical extent of, or business activities covered by any provision of this Agreement be in excess of that which is valid and enforceable under applicable law, then such provision shall be construed to cover only that duration, extent or activities which may validly and enforceably be covered. To the extent any provision of this Agreement shall be declared invalid or unenforceable for any reason by any Governmental Entity in any jurisdiction, this Agreement (or provision thereof) shall remain valid and enforceable in each other jurisdiction where it applies. Employee acknowledges the uncertainty of the law in this respect and expressly stipulates that this Agreement shall be given the construction which renders its provisions valid and enforceable to the maximum extent (not exceeding its express terms) possible under applicable law. 4.6 SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon and inure to the benefit of the parties hereto, the heirs and legal representatives of Employee and the successors and assigns of the Company. Employee shall not be entitled to assign his obligations hereunder. The Company may assign its rights under this Agreement to successors and assigns of the Company that succeed to all or substantially all of that portion of the Company's business to which the employment of Employee principally relates. Employee agrees that, upon request therefor, Employee will, in writing, acknowledge and consent to any such assignment of this Agreement. 4.7 REPRESENTATIONS AND WARRANTIES. To Employee's knowledge, Employee represents and warrants that this Agreement is a legal, valid and binding obligation, enforceable against Employee in accordance with its terms to the fullest extent permitted under applicable federal, state or local law. 4.8 EFFECTIVE TIME. This Agreement shall become effective upon the closing of the transaction contemplated by the Purchase Agreement. 4.9 INDEPENDENT REVIEW AND ADVICE. Employee represents and warrants that Employee has carefully read this Agreement; that Employee executes this Agreement with full knowledge of the contents of this Agreement, the legal consequences thereof, and any and all rights which each party may have with respect to one another; that Employee has had the opportunity to receive independent legal advice with respect to the matters set forth in this Agreement and with respect to the rights and asserted rights arising out of such matters; that Employee has been advised to, and has had the opportunity to, consult with Employee's personal attorney prior to entering into this Agreement; and that Employee is entering into this Agreement of Employee's own free will. Employee expressly agrees that he or she has no expectations or understandings contrary to the Agreement and no usage of trade or regular practice in the industry shall be used to modify this Agreement. The parties agree that this Agreement shall not be construed for or against either party in any interpretation thereof. Employee acknowledges that Sills Cummis Radin Tischman Epstein & Gross P.A. and Stroock & Stroock & Lavan LLP represent the Company and do not represent Employee in connection with this Agreement, the Purchase Agreement, or any of the transactions contemplated thereby or hereby. IN WITNESS WHEREOF, the parties have executed this Non-Competition and Non-Solicitation Agreement effective as of the date first written above.

By: __________________________ Name: [_____________________] Title: Assistant Secretary EXHIBIT G FORM OF INDEMNIFICATION AGREEMENT This Indemnification Agreement (the "AGREEMENT") is entered into as of the ___ day of _________, 2003, by and among ____________________, a Delaware corporation (the "COMPANY") and the indemnitees listed on the signature pages hereto (each an "INDEMNITEE" and collectively, the "INDEMNITEES"). RECITALS A. The Company and the Indemnitees recognize the continued difficulty in obtaining liability insurance for the Company's directors, officers, employees, controlling persons, agents and fiduciaries, the significant increases in the cost of such insurance and the general reductions in the coverage of such insurance. B. The Company and the Indemnitees further recognize the substantial increase in corporate litigation in general, subjecting directors, officers, employees, controlling persons, agents and fiduciaries to expensive litigation risks at the same time as the availability and coverage of liability insurance has been severely limited. C. The Indemnitees do not regard the prior protection available as adequate under the circumstances, and the Indemnitees and other directors, officers, employees, controlling persons, agents and fiduciaries of the Company are not willing to serve in such capacities without additional protection, so the Company and the Indemnitees desire to enter into this Agreement. D. The Company (i) desires to attract and retain the involvement of highly qualified groups, such as the Indemnitees, to serve the Company and, in part, to induce each Indemnitee to be involved with the Company and (ii) wishes to provide for the indemnification and advancing of expenses to each Indemnitee to the maximum extent permitted by law. E. In view of the considerations set forth above, the Company desires that each Indemnitee be indemnified by the Company as set forth herein. NOW, THEREFORE, the Company and each Indemnitee hereby agrees as follows: 1. INDEMNIFICATION. a. INDEMNIFICATION OF EXPENSES. The Company shall indemnify and hold harmless each Indemnitee (including, without limitation, its respective directors, officers, partners, employees, agents and spouses) and each person who controls any of them or who may be liable within the meaning of Section 15 of the Securities Act of 1933, as amended (the "SECURITIES ACT"), or Section 20 of the Securities Exchange Act of 1934, as amended (the "EXCHANGE ACT") to the fullest extent permitted by law if such Indemnitee was or is or becomes a party to or witness or other participant in, or is threatened to be made a party to or witness or other participant in, any threatened, pending or completed action, suit, proceeding or alternative dispute resolution mechanism, or any hearing, inquiry or investigation that such Indemnitee reasonably believes might lead to the institution of any such action, suit, proceeding or alternative dispute resolution mechanism, whether civil, criminal, administrative, investigative or other (hereinafter a "CLAIM") by reason of (or arising in part out of) any event or occurrence related to the fact that such Indemnitee is or was a director, officer, employee, controlling person, agent or fiduciary of the Company, or any subsidiary of the Company, or is or was serving at the request of the Company as a director, officer, employee, controlling person, agent or fiduciary of another corporation, partnership, joint venture, trust or other enterprise, or by reason of any action or inaction on the part of such Indemnitee while serving in such capacity including, without limitation, any and all losses, claims, damages, expenses and liabilities, joint or several (including, without limitation, any investigation, legal and other expenses incurred in connection with, and any amount paid in settlement of, any action, suit, proceeding or any claim asserted) under the Securities Act, the Exchange Act or other federal or state statutory law or regulation, at common law or otherwise, which relate directly or indirectly to the registration, purchase, sale or ownership of any securities of the Company or to any fiduciary obligation owed with respect thereto (hereinafter an "INDEMNIFICATION EVENT") against any and all expenses (including, without limitation, reasonable attorneys' fees and all other reasonable costs, expenses and obligations incurred in connection with investigating, defending a witness in or participating in (including, without limitation, on appeal), or preparing to defend, be a witness in or participate in, any such action, suit, proceeding, alternative dispute resolution mechanism, hearing, inquiry or investigation), judgments, fines, penalties and amounts paid in settlement (if such settlement is approved in advance by the Company, which approval shall not be unreasonably withheld) of such Claim and any federal, state, local or foreign taxes imposed on such Indemnitee as a result of the actual or deemed receipt of any payments under this Agreement (collectively, hereinafter "EXPENSES"), including, without limitation, all interest, assessments and other charges paid or payable in connection with or in respect of such Expenses. Such payment of allowed Expenses shall be made by the Company as soon as practicable but in any event no later than five (5) days after written demand by the Indemnitee therefor is presented to the Company. b. REVIEWING PARTY. Notwithstanding the foregoing, (i) the obligations of the Company under Section 1(a) shall be subject to the condition that the Reviewing Party (as described in Section 10(e) hereof) shall not have determined (in a written opinion, in any case in which the Independent Legal Counsel referred to in Section 10(d) hereof is involved) that an Indemnitee would not be permitted to be indemnified under applicable law, and (ii) each Indemnitee acknowledges and agrees that the obligation of the Company to make an advance payment of Expenses to an Indemnitee pursuant to Section 2(a) (an "EXPENSE ADVANCE") shall be subject to the condition that, if, when and to the extent that the Reviewing Party determines that an Indemnitee would not be permitted to be so indemnified under applicable law, the Company shall be entitled to be reimbursed by such Indemnitee (who hereby agrees to reimburse the Company) for all such amounts theretofore paid; PROVIDED, HOWEVER, that if such Indemnitee has commenced or thereafter commences legal proceedings in a court of competent jurisdiction to secure a determination that such Indemnitee should be indemnified under applicable law, any determination made by the Reviewing Party that such Indemnitee would not be permitted to be indemnified under applicable law shall not be binding and such Indemnitee shall not be required to reimburse the Company for any Expense Advance until a final judicial determination is made with respect thereto (as to which all rights of appeal therefrom have been exhausted or lapsed). An Indemnitee's obligation to reimburse the Company for any Expense Advance shall be unsecured and no interest shall be charged thereon if such reimbursement is made within thirty (30) days of such final judicial determination, unless otherwise required by the court. If there has not been a Change in Control (as defined in Section 10(c) hereof), the Reviewing Party shall be selected by the Board of Directors, and if there has been such a Change in Control (other than a Change in Control that has been approved by a majority of the Company's Board of Directors who were directors immediately prior to such Change in Control), the Reviewing Party shall be the Independent Legal Counsel referred to in Section 10(d) hereof. If there has been no determination by the Reviewing Party or if the Reviewing Party determines that an Indemnitee substantively would not be permitted to be indemnified in whole or in part under applicable law, the Indemnitee shall have the right to commence litigation seeking an initial determination by the court or challenging any such determination by the Reviewing Party or any aspect thereof, including, without limitation, the legal or factual bases therefor, and the Company hereby consents to service of process and to appear in any such proceeding. Any determination by the Reviewing Party otherwise shall be conclusive and binding on the Company and such Indemnitee. c. CONTRIBUTION. If the indemnification provided for in Section 1(a) above for any reason is held by a court of competent jurisdiction to be unavailable to an Indemnitee in respect of any losses, claims, damages, expenses or liabilities referred to therein, then the Company, in lieu of indemnifying such Indemnitee thereunder, shall contribute to the amount paid or payable by such Indemnitee as a result of such losses, claims, damages, expenses or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Indemnitees, or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Indemnitees in connection with the action or inaction that resulted in such losses, claims, damages, expenses or liabilities, as well as any other relevant equitable considerations. In connection with the registration of the Company's securities, the relative benefits received by the Company and the Indemnitees shall be deemed to be in the same respective proportions that the net proceeds from the offering (before deducting expenses) received by the Company and the Indemnitees, in each case as set forth in the table on the cover page of the applicable prospectus, bear to the aggregate public offering price of the securities so offered. The relative fault of the Company and the Indemnitees shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Indemnitees and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Indemnitees agree that it would not be just and equitable if contribution pursuant to this Section 1(c) were determined by pro rata or per capita allocation or by any other method of allocation that does not take account of the equitable considerations referred to in the immediately preceding paragraph. In connection with the registration of the Company's securities, in no event shall an Indemnitee be required to contribute any amount under this Section 1(c) in excess of the lesser of (i) that proportion of the total of such losses, claims, damages or liabilities that are indemnified against, equal to the proportion of the total securities sold under such registration statement that are being sold by such Indemnitee or (ii) the proceeds received by such Indemnitee from its sale of securities under such registration statement. No person found guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not found guilty of such fraudulent misrepresentation. d. SURVIVAL REGARDLESS OF INVESTIGATION. The indemnification and contribution provided for in this Section 1 will remain in full force and effect regardless of any investigation made by or on behalf of the Indemnitees or any officer, director, employee, agent or controlling person of the Indemnitees. e. CHANGE IN CONTROL. The Company agrees that if there is a Change in Control of the Company (other than a Change in Control that has been approved by a majority of the Company's Board of Directors who were directors immediately prior to such Change in Control) then, with respect to all matters thereafter arising concerning the rights of the Indemnitees to payments of Expenses under this Agreement or any other agreement or under the Company's Certificate of Incorporation or Bylaws as now or hereafter in effect, Independent Legal Counsel (as defined in Section 10(d) hereof) shall be selected by the Indemnitees and approved by the Company (which approval shall not be unreasonably withheld). Such counsel, among other things, shall render its written opinion to the Company and the Indemnitees as to whether and to what extent the Indemnitees would be permitted to be indemnified under applicable law. The Company agrees to abide by such opinion and to pay the reasonable fees of the Independent Legal Counsel referred to above and to fully indemnify such counsel against any and all expenses (including, without limitation, reasonable attorneys' fees), claims, liabilities and damages arising out of or relating to this Agreement or its engagement pursuant hereto. f. MANDATORY PAYMENT OF EXPENSES. Notwithstanding any other provision of this Agreement, to the extent that the Indemnitees have been successful on the merits or otherwise, including, without limitation, the dismissal of an action without prejudice, in the defense of any action, suit, proceeding, inquiry or investigation referred to in Section 1(a) hereof or in the defense of any claim, issue or matter therein, each Indemnitee shall be indemnified against all Expenses incurred by such Indemnitee in connection herewith. 2. EXPENSES; INDEMNIFICATION PROCEDURE. a. ADVANCEMENT OF EXPENSES. The Company shall advance all Expenses incurred by the Indemnitees. The advances to be made hereunder shall be paid by the Company to the Indemnitees as soon as practicable but in any event no later than five (5) days after written demand by such Indemnitees therefor to the Company. b. NOTICE/COOPERATION BY THE INDEMNITEES. Each Indemnitee shall give the Company notice in writing as soon as practicable of any Claim made against such Indemnitee for which indemnification will or could be sought under this Agreement. Notice to the Company shall be directed to the Company's Chief Executive Officer at the Company's address (or such other address as the Company shall designate in writing to the Indemnitees). c. NO PRESUMPTIONS; BURDEN OF PROOF. For purposes of this Agreement, the termination of any Claim by judgment, order, settlement (whether with or without court approval) or conviction, or upon a plea of nolo contendere, or its equivalent, shall not create a presumption that the Indemnitees did not meet any particular standard of conduct or have any particular belief or that a court has determined that indemnification is not permitted by applicable law. In addition, neither the failure of the Reviewing Party to have made a determination as to whether an Indemnitee has met any particular standard of conduct or had any particular belief, nor an actual determination by the Reviewing Party that an Indemnitee has not met such standard of conduct or did not have such belief, prior to the commencement of legal proceedings by such Indemnitee to secure a judicial determination that such Indemnitee should be indemnified under applicable law, shall be a defense to an Indemnitee's claim or create a presumption that such Indemnitee has not met any particular standard of conduct or did not have any particular belief. In connection with any determination by the Reviewing Party or otherwise as to whether an Indemnitee is entitled to be indemnified hereunder, the burden of proof shall be on the Company to establish that an Indemnitee is not so entitled. d. NOTICE TO INSURERS. If, at the time of the receipt by the Company of a notice of a Claim pursuant to Section 2(b) hereof, the Company has liability insurance in effect that may cover such Claim, the Company shall give prompt notice of the commencement of such Claim to the insurers in accordance with the procedures set forth in each of the policies. The Company shall thereafter take all necessary or desirable action to cause such insurers to pay, on behalf of the Indemnitees, all amounts payable as a result of such action, suit, proceeding, inquiry or investigation in accordance with the terms of such policies. e. SELECTION OF COUNSEL. In the event the Company shall be obligated hereunder to pay the Expenses of any Claim, the Company shall be entitled to assume the defense of such Claim, with counsel approved by the applicable Indemnitee, upon the delivery to such Indemnitee of written notice of its election to do so. After delivery of such notice, approval of such counsel by the Indemnitee and the retention of such counsel by the Company, the Company will not be liable to such Indemnitee under this Agreement for any fees of counsel subsequently incurred by such Indemnitee with respect to the same Claim; PROVIDED that, (i) the Indemnitee shall have the right to employ such Indemnitee's counsel in any such Claim at the Indemnitee's expense and (ii) if (A) the employment of counsel by the Indemnitee has been previously authorized by the Company, (B) such Indemnitee shall have reasonably concluded that there is a conflict of interest between the Company and such Indemnitee in the conduct of any such defense, or (C) the Company shall not continue to retain such counsel to defend such Claim, then the fees and expenses of the Indemnitee's counsel shall be at the expense of the Company. The Company shall have the right to conduct such defense as it sees fit in its sole discretion, including, without limitation, the right to settle any claim against any Indemnitee without the consent of such Indemnitee. 3. ADDITIONAL INDEMNIFICATION RIGHTS; NONEXCLUSIVITY. a. SCOPE. The Company hereby agrees to indemnify the Indemnitees to the fullest extent permitted by law, even if such indemnification is not specifically authorized by the other provisions of this Agreement, the Company's Certificate of Incorporation, the Company's Bylaws or by statute. In the event of any change after the date of this Agreement in any applicable law, statute or rule that expands the right of a Delaware corporation to indemnify a member of its Board of Directors or an officer, employee, controlling person, agent or fiduciary, it is the intent of the parties hereto that the Indemnitees shall enjoy by this Agreement the greater benefits afforded by such change. In the event of any change after the date of this Agreement in any applicable law, statute or rule that narrows the right of a Delaware corporation to indemnify a member of its Board of Directors or an officer, employee, agent or fiduciary, such change, to the extent not otherwise required by such law, statute or rule to be applied to this Agreement, shall have no effect on this Agreement or the parties' rights and obligations hereunder except as set forth in Section 8(a) hereof. b. NONEXCLUSIVITY. The indemnification provided by this Agreement shall be in addition to any rights to which the Indemnitees may be entitled under the Company's Certificate of Incorporation, its Bylaws, any agreement, any vote of stockholders or disinterested directors, the Delaware General Corporation Law, or otherwise. The indemnification provided under this Agreement shall continue as to each Indemnitee for any action such Indemnitee took or did not take while serving in an indemnified capacity even though the Indemnitee may have ceased to serve in such capacity. 4. NO DUPLICATION OF PAYMENTS. The Company shall not be liable under this Agreement to make any payment in connection with any Claim made against any Indemnitee to the extent such Indemnitee has otherwise actually received payment (under any insurance policy, Certificate of Incorporation, Bylaw or otherwise) of the amounts otherwise indemnifiable hereunder. 5. PARTIAL INDEMNIFICATION. If any Indemnitee is entitled under any provision of this Agreement to indemnification by the Company for any portion of Expenses incurred in connection with any Claim, but not, however, for all of the total amount thereof, the Company shall nevertheless indemnify such Indemnitee for the portion of such Expenses to which such Indemnitee is entitled. 6. MUTUAL ACKNOWLEDGEMENT. The Company and each Indemnitee acknowledge that in certain instances, Federal law or applicable public policy may prohibit the Company from indemnifying its directors, officers, employees, controlling persons, agents or fiduciaries under this Agreement or otherwise. Each Indemnitee understands and acknowledges that the Company has undertaken or may be required in the future to undertake with the Securities and Exchange Commission to submit the question of indemnification to a court in certain circumstances for a determination of the Company's rights under public policy to indemnify the Indemnitees. 7. LIABILITY INSURANCE. To the extent the Company maintains liability insurance applicable to directors, officers, employees, control persons, agents or fiduciaries, each of the Indemnitees shall be covered by such policies in such a manner as to provide the Indemnitees the same rights and benefits as are accorded to the most favorably insured of the Company's directors, if such Indemnitee is a director, or of the Company's officers, if such Indemnitee is not a director of the Company but is an officer; or of the Company's key employees, controlling persons, agents or fiduciaries, if such Indemnitee is not an officer or director but is a key employee, agent, control person, or fiduciary. 8. EXCEPTIONS. Any other provision herein to the contrary notwithstanding, the Company shall not be obligated pursuant to the terms of this Agreement: a. CLAIMS INITIATED BY AN INDEMNITEE. To indemnify or advance expenses to any Indemnitee with respect to Claims initiated or brought voluntarily by such Indemnitee and not by way of defense, except (i) with respect to actions or proceedings to establish or enforce a right to indemnify under this Agreement or any other agreement or insurance policy or under the Company's Certificate of Incorporation or Bylaws now or hereafter in effect relating to Claims for Indemnifiable Events, (ii) in specific cases if the Board of Directors has approved the initiation or bringing of such Claim, or (iii) as otherwise required under Section 145 of the Delaware General Corporation Law, regardless of whether such Indemnitee ultimately is determined to be entitled to such indemnification, advance expense payment or insurance recovery, as the case may be; or b. CLAIMS UNDER SECTION 16(B). To indemnify any Indemnitee for expenses and the payment of profits arising from the purchase and sale by such Indemnitee of securities in violation of Section 16(b) of the Exchange Act or any similar successor statute; or c. CLAIMS EXCLUDED UNDER SECTION 145 OF THE DELAWARE GENERAL CORPORATION LAW. To indemnify any Indemnitee if indemnification is expressly prohibited by law, subject to the right of the Indemnitee to challenge such determination pursuant to Section 1(b). d. CLAIMS RESULTING FROM WILLFUL MISCONDUCT OR FRAUD. To indemnify or advance Expenses to any Indemnitee with respect to Claims resulting from such Indemnitee's willful misconduct or fraud on the part of the Indemnitee. 9. PERIOD OF LIMITATIONS. No legal action shall be brought and no cause of action shall be asserted by or in the right of the Company against any Indemnitee or any Indemnitee's estate, spouse, heirs, executors or personal or legal representatives after the expiration of five (5) years from the date of accrual of such cause of action, and any claim or cause of action of the Company shall be extinguished and deemed released unless asserted by the timely filing of a legal action within such five (5)-year period; PROVIDED, HOWEVER, that if any shorter period of limitations is otherwise applicable to any such cause of action, such shorter period shall govern. 10. CONSTRUCTION OF CERTAIN PHRASES. a. For purposes of this Agreement, references to the "COMPANY" shall include, in addition to the resulting corporation, any constituent corporation (including, without limitation, any constituent of a constituent) absorbed in a consolidation or merger that, if its separate existence had continued, would have had power and authority to indemnify its directors, officers, employees, agents or fiduciaries, so that if an Indemnitee is or was a director, officer, employee, agent, control person, or fiduciary of such constituent corporation, or is or was serving at the request of such constituent corporation as a director, officer, employee, control person, agent or fiduciary of another corporation, partnership, joint venture, employee benefit plan, trust or other enterprise, each Indemnitee shall stand in the same position under the provisions of this Agreement with respect to the resulting or surviving corporation as each Indemnitee would have with respect to such constituent corporation if its separate existence had continued. b. For purposes of this Agreement, references to "OTHER ENTERPRISES" shall include, without limitation, employee benefit plans; references to "FINES" shall include, without limitation, any excise taxes assessed on any Indemnitee with respect to an employee benefit plan; and references to "SERVING AT THE REQUEST OF THE COMPANY" shall include any service as a director, officer, employee, agent or fiduciary of the Company that imposes duties on, or involves services by, such director, officer, employee, agent or fiduciary with respect to an employee benefit plan, its participants or its beneficiaries; and if any Indemnitee acted in good faith and in a manner such Indemnitee reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan, such Indemnitee shall be deemed to have acted in a manner "NOT OPPOSED TO THE BEST INTERESTS OF THE COMPANY" as referred to in this Agreement. c. For purposes of this Agreement a "CHANGE IN CONTROL" shall be deemed to have occurred if (i) any "person" (as such term is used in Sections 13(d)(3) and 14(d)(2) of the Exchange Act), other than a trustee or other fiduciary holding securities under an employee benefit plan of the Company or a corporation owned directly or indirectly by the stockholders of the Company in substantially the same proportions as their ownership of stock of the Company, (A) who is or becomes the beneficial owner, directly or indirectly, of securities of the Company representing ten percent (10%) or more of the combined voting power of the Company's then outstanding Voting Securities (as defined in Section 10(f) hereof), increases his beneficial ownership of such securities by five percent (5%) or more over the percentage so owned by such person, or (B) becomes the "beneficial owner" (as defined in Rule 13d-3 under said Exchange Act), directly or indirectly, of securities of the Company representing more than twenty percent (20%) of the total voting power represented by the Company's then outstanding Voting Securities, (ii) during any period of two (2) consecutive years, individuals who at the beginning of such period constitute the Board of Directors of the Company and any new director whose election by the Board of Directors or nomination for election by the Company's stockholders was approved by a vote of at least two-thirds (2/3) of the directors then still in office who either were directors at the beginning of the period or whose election or nomination for election was previously so approved, cease for any reason to constitute a majority thereof, or (iii) the stockholders of the Company approve a merger or consolidation of the Company with any other corporation other than a merger or consolidation that would result in the Voting Securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into Voting Securities of the surviving entity) at least eighty percent (80%) of the total voting power represented by the Voting Securities of the Company or such surviving entity outstanding immediately after such merger or consolidation, or the stockholders of the Company approve a plan of complete liquidation of the Company or an agreement for the sale or disposition by the Company of (in one transaction or a series of transactions) all or substantially all of the Company's assets. d. For purposes of this Agreement, "INDEPENDENT LEGAL COUNSEL" shall mean an attorney or firm of attorneys, selected in accordance with the provisions of Section 2(e) hereof, who shall not have otherwise performed services for the Company or any Indemnitee within the last three (3) years (other than with respect to matters concerning the right of any Indemnitee under this Agreement, or of other indemnitees under similar indemnity agreements). e. For purposes of this Agreement, a "REVIEWING PARTY" shall mean any appropriate person or body consisting of a member or members of the Company's Board of Directors or any other person or body appointed by the Board of Directors who is not a party to the particular Claim for which the Indemnitees are seeking indemnification, or Independent Legal Counsel. f. For purposes of this Agreement, "VOTING SECURITIES" shall mean any securities of the Company that vote generally in the election of directors. 11. AMENDMENT AND TERMINATION. Any term hereof may be amended (either generally or in a particular instance and either retroactively or prospectively) only with the written consent of (a) the Company; and (b) each Indemnitee, if any, adversely affected by such amendment. Any amendment so effected shall be binding upon the Company and all Indemnitees and all of their respective successors and assigns whether or not such person or entity entered into or approved such amendment or waiver. The observance of any term hereof may be waived by a party with respect to its own interests (either generally or in a particular instance and either retroactively or prospectively) only with the written consent of the party so waiving the observance of such term. In no event shall such waiver of any rights hereunder constitute the waiver of such rights in any future instance unless the waiver so specifies in writing. Notwithstanding anything to the contrary in this Agreement, the Company may add additional Indemnitees at any time to this Agreement without the consent of any other Indemnitee. 12. ATTORNEYS' FEES. In the event that any action is instituted by an Indemnitee under this Agreement or under any liability insurance policies maintained by the Company to enforce or interpret any of the terms hereof or thereof, any Indemnitee shall be entitled to be paid all Expenses incurred by such Indemnitee with respect to such action, regardless of whether such Indemnitee is ultimately successful in such action, and shall be entitled to the advancement of Expenses with respect to such action, unless, as a part of such action, a court of competent jurisdiction over such action determines that each of the material assertions made by such Indemnitee as a basis for such action was not made in good faith or was frivolous. In the event of an action instituted by or in the name of the Company under this Agreement to enforce or interpret any of the terms of this Agreement, the Indemnitee shall be entitled to be paid all Expenses incurred by such Indemnitee in defense of such action (including, without limitation, costs and expenses incurred with respect to such Indemnitee's counterclaims and cross-claims made in such action), and shall be entitled to the advancement of Expenses with respect to such action, unless, as a part of such action, a court having jurisdiction over such action determines that each of such Indemnitee's material defenses to such action was made in bad faith or was frivolous. 13. BINDING EFFECT. This Agreement shall be binding upon and inure to the benefit of and be enforceable by the parties hereto and their respective successors, assigns, including, without limitation, any direct or indirect successor by purchase, merger, consolidation or otherwise to all or substantially all of the business and/or assets of the Company, spouses, heirs, and personal and legal representatives. 14. CHOICE OF LAW. This Agreement shall be governed by and its provisions construed and enforced in accordance with the laws of the State of Delaware, as applied to contracts between Delaware residents, entered into and to be performed entirely within the State of Delaware, without regard to the conflict of laws principles thereof. 15. CONSENT TO JURISDICTION. The Company and each Indemnitee each hereby irrevocably consents to the jurisdiction of the courts of the State of Delaware for all purposes in connection with any action or proceeding that arises out of or relates to this Agreement and agree that any action instituted under this Agreement shall be commenced, prosecuted and continued only in the Court of Chancery of the State of Delaware in and for New Castle County, which shall be the exclusive and only proper forum for adjudicating such a claim. 16. CORPORATE AUTHORITY. The Board of Directors of the Company and its stockholders have approved the terms of this Agreement. 17. COUNTERPARTS. This Agreement may be executed in one (1) or more counterparts, each of which shall constitute an original. 18. INTEGRATION AND ENTIRE AGREEMENT. Subject to Section 3(b), this Agreement sets forth the entire understanding between the parties hereto and supersedes and merges all previous written and oral negotiations, commitments, understandings and agreements relating to the subject matter hereof between the parties hereto. 19. NO CONSTRUCTION AS EMPLOYMENT AGREEMENT. Nothing contained in this Agreement shall be construed as giving any Indemnitee any right to be retained in the employ of the Company or any of its subsidiaries. 20. NOTICE. All notices and other communications required or permitted hereunder shall be in writing, shall be effective when given, and shall in any event be deemed to be given (i) two (2) days after deposit with the U.S. Postal Service or other applicable postal service, if delivered by first class mail, postage prepaid, (ii) upon delivery, if delivered by hand, (iii) one (1) business day after the business day of deposit with Federal Express or similar overnight courier, freight prepaid, or (iv) one (1) day after the business day of delivery by facsimile transmission, if deliverable by facsimile transmission, with copy by first class mail, postage prepaid, and shall be addressed if to the Indemnitees, at each Indemnitee's address as set forth beneath the Indemnitees' signatures to this Agreement and if to the Company at the address of its principal corporate offices (Attention: Secretary) or at such other address as such party may designate by ten (10) days' advance written notice to the other party hereto. 21. SEVERABILITY. The provisions of this Agreement shall be severable in the event that any of the provisions hereof (including, without limitation, any provision within a single section, paragraph or sentence) are held by a court of competent jurisdiction to be invalid, void or otherwise unenforceable, and the remaining provisions shall remain enforceable to the fullest extent permitted by law. Furthermore, to the fullest extent possible, the provisions of this Agreement (including, without limitation, each portion of this Agreement containing any provision held to be invalid, void or otherwise unenforceable, that is not itself invalid, void or unenforceable) shall be construed so as to give effect to the intent manifested by the provision held invalid, illegal or unenforceable. 22. SUBROGATION. In the event of payment under this Agreement, the Company shall be subrogated to the extent of such payment to all of the rights of recovery of an Indemnitee who shall execute all documents required and shall do all acts that may be necessary to secure such rights and to enable the Company effectively to bring suit to enforce such rights. 23. SUCCESSORS AND ASSIGNS. The Company shall require and cause any successor (whether direct or indirect by purchase, merger, consolidation or otherwise) to all, substantially all, or a substantial part, of the business and/or assets of the Company, by written agreement in form and substance satisfactory to each Indemnitee, expressly to assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform if no such succession had taken place. This Agreement shall continue in effect with respect to Claims relating to Indemnifiable Events regardless of whether any Indemnitee continues to serve as a director, officer, employee, agent, controlling person, or fiduciary of the Company or of any other enterprise, including, without limitation, subsidiaries of the Company, at the Company's request.

The Corporation shall, as soon as practicable thereafter, issue and deliver at such office to such holder of Series A Preferred Stock, or to the nominee or nominees of such holder, a certificate or certificates for the number of shares of Common Stock to which such holder shall be entitled as set forth above. Such conversion shall be deemed to have been made immediately prior to the close of business on the date of such surrender of the shares of Series A Preferred Stock to be converted, and the person or persons entitled to receive the shares of Common Stock issuable upon such conversion shall be treated for all purposes as the record holder or holders of such shares of Common Stock as of such date. (3) In the event the Corporation should at any time fix a record date for the effectuation of a split or subdivision of the outstanding shares of Common Stock or the determination of holders of Common Stock entitled to receive a dividend or other distribution payable in additional shares of Common Stock or other securities or rights convertible into, or entitling the holder thereof to receive directly or indirectly, additional shares of Common Stock (hereinafter referred to as "Common Stock Equivalents") without payment of any consideration by such holder for the additional shares of Common Stock or the Common Stock Equivalents (including the additional shares of Common Stock issuable upon conversion or exercise thereof) or with payment that is less than the Series A Conversion Price then in effect, then, as of such record date (or the date of such dividend distribution, split or subdivision if no record date is fixed), the Series A Conversion Price of the Series A Preferred Stock shall be appropriately decreased so that the number of shares of Common Stock issuable on conversion of each share of such series shall be increased in proportion to such increase of the aggregate of (a) shares of Common Stock outstanding and (b) those issuable with respect to such Common Stock Equivalents, with the number of shares issuable with respect to Common Stock Equivalents determined from time to time as provided in Section 4(a)(5) below. (4) If the number of shares of Common Stock outstanding at any time is decreased by a combination of the outstanding shares of Common Stock, then, following the record date of such combination, the Series A Conversion Price for the Series A Preferred Stock shall be appropriately increased so that the number of shares of Common Stock issuable on conversion of each share of such series shall be decreased in proportion to such decrease in outstanding shares. (5) The following provisions shall apply for purposes of this Section 4(a): (a) The aggregate maximum number of shares of Common Stock deliverable upon conversion or exercise of Common Stock Equivalents (assuming the satisfaction of any conditions to convertibility or exercisability, including, without limitation, the passage of time, but without taking into account potential antidilution adjustments) shall be deemed to have been issued at the time such Common Stock Equivalents were issued. (b) In the event of any change in the number of shares of Common Stock deliverable or in the consideration payable to the Corporation upon conversion or exercise of such Common Stock Equivalents including, but not limited to, a change resulting from the antidilution provisions thereof, the Series A Conversion Price of the Series A Preferred Stock, to the extent in any way affected by or computed using such Common Stock Equivalents, shall be recomputed to reflect such change, but no further adjustment shall be made for the actual issuance of Common Stock or any payment of such consideration upon the exercise of any such options or rights or the conversion or exchange of such securities. (c) Upon the termination or expiration of the convertibility or exercisability of any such Common Stock Equivalents, the Series A Conversion Price of the Series A Preferred Stock, to the extent in any way affected by or computed using such Common Stock Equivalents, shall be recomputed to reflect the issuance of only the number of shares of Common Stock (and Common Stock Equivalents which remain convertible or exercisable) actually issued upon the conversion or exercise of such Common Stock Equivalents. (5) EXCHANGE RIGHT. Provided that (a) all of the shares of Series A Preferred Stock initially issued and sold by the Corporation to Elan International Services, Ltd., a Bermuda exempted limited liability company ("EIS"), have not been converted, as provided in Section 4 above, and (b) the Exchange Termination Date (as defined below) shall not have occurred, the holders of the Series A Preferred Stock (acting by act of the majority holders thereof) shall have the right to exchange all of their shares of Series A Preferred Stock (the "Exchange Right") of the Corporation for initially 3,612 shares of non-voting convertible preferred shares (the "Preferred Shares") (as adjusted for any combinations or divisions or similar recapitalizations) of Medizyme Pharmaceutical Ltd., a Bermuda exempted limited liability company ("Newco"), held by the Corporation, so that, in any event, after giving effect to the exercise of the Exchange Right, EIS and the Corporation will each hold 50% of the total outstanding share capital of Newco, on a fully diluted basis, assuming that neither EIS nor the Corporation has sold any shares of Newco. Upon exercise of the Exchange Right, the Preferred Shares held by the Corporation shall be transferred legally and beneficially to EIS. The rights of the holders to exercise the Exchange Right shall commence at any time after October 7, 2002 and shall terminate and be of no further force and effect on the date that is the later of (i) seven months thereafter and (ii) the completion of Newco's development period, as agreed in the business plan of Newco and as set forth in the Subscription, Joint Development and Operating Agreement dated as of January 7th, 2000, among Elan Pharmaceuticals Technologies, a division of Elan Corporation, plc, an Irish public limited company, EIS, Elan Pharma International Limited, an Irish corporation ("EPIL"), Newco and the Corporation (the "Exchange Termination Date"). Upon exercise of the Exchange Right, the shares of Series A Preferred Stock originally purchased from the Corporation, but not including any of the accrued and unpaid dividends thereon (all of which shall remain outstanding), shall be canceled and shall no longer be entitled to any rights in the Corporation. If any shares of the Series A Preferred Stock (other than shares in respect of accrued dividends) are converted pursuant to Section 4(a), to shares of Common Stock, the Exchange Right with respect to the shares of Series A Preferred Stock originally purchased from the Corporation, but not including any of the accrued and unpaid dividends thereon, shall be canceled and shall no longer be entitled to any rights in the Corporation. In order to exercise the Exchange Right, the holders shall provide written notice thereof to the Corporation, setting forth (a) the fact that such holders intend to exercise the Exchange Right, and (b) the proposed date for such exercise (the "Exercise Date"), which shall be between 10 and 30 days after the date of such notice. On the Exercise Date, (y) the holders shall tender their shares of Series A Preferred Stock to the Corporation for cancellation, and (z) the Corporation shall cause to be delivered to EIS, acting on behalf of such holders, such shares of Newco. The holders and the Corporation shall take all other necessary or appropriate actions in connection with or to effect such closing. Section 5(c) of the Securities Purchase Agreement, dated as of January 7th, 2000, between EIS and the Corporation contains certain additional provisions relating to the Exchange Right. (6) OTHER DISTRIBUTIONS. On or prior to the Conversion Termination Date, in the event the Corporation shall declare a distribution payable in securities of other entities, evidences of indebtedness issued by the Corporation or other entities, assets (excluding cash dividends) or options or rights not referred to in Section 4, then, in each such case for the purpose of this Section 6, the holders of the Series A Preferred Stock shall be entitled to a proportionate share of any such distribution as though they were the holders of the number of shares of Common Stock of the Corporation into which their shares of Series A Preferred Stock would be convertible as of the record date fixed for the determination of the holders of Common Stock of the Corporation entitled to receive such distribution. (7) RECAPITALIZATIONS. On or prior to the Conversion Termination Date, if at any time or from time to time there shall be a recapitalization of the Common Stock (other than a subdivision, combination or merger or sale of assets provided for in Section 3 or Section 4 hereof) provision shall be made so that the holders of the Series A Preferred Stock shall thereafter be entitled to receive upon conversion of the Series A Preferred Stock the number of shares of stock or other securities or property of the Corporation or otherwise, to which a holder of Common Stock deliverable upon conversion would have been entitled on such recapitalization. In any such case, appropriate adjustment shall be made in the application of the provisions of Section 4 with respect to the rights of the holders of the Series A Preferred Stock after the recapitalization to the end that the provisions of Section 4 (including adjustment of the Series A Conversion Price then in effect and the number of shares purchasable upon conversion of the Series A Preferred Stock) shall be applicable after that event as nearly equivalent as may be practicable. (8) NO IMPAIRMENT. The Corporation will not, by amendment of Certificate of Incorporation or through any reorganization, recapitalization, transfer of assets, consolidation, merger, dissolution, issuance or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Corporation, but will at all times in good faith assist in the carrying out of all the provisions hereof and in the taking of all such action as may be necessary or appropriate in order to protect the Series A Conversion Right and Exchange Right of the holders of the Series A Preferred Stock against impairment. (9) NO FRACTIONAL SHARES AND CERTIFICATE AS TO ADJUSTMENTS. a) No fractional shares shall be issued upon the conversion of any share or shares of the Series A Preferred Stock, and the number of shares of Common Stock to be issued shall be rounded to the nearest whole share. Whether or not fractional shares are issuable upon such conversion shall be determined on the basis of the aggregate number of shares of Series A Preferred Stock each holder is at the time converting into Common Stock and the aggregate number of shares of Common Stock issuable to each such holder upon such conversion. b) Upon the occurrence of each adjustment or readjustment of the Series A Conversion Price pursuant to Section 4, the Corporation, at its expense, shall promptly compute such adjustment or readjustment in accordance with the terms hereof and prepare and furnish to each holder of shares of Series A Preferred Stock a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based. The Corporation shall, upon the written request at any time of any holder of Series A Preferred Stock, furnish or cause to be furnished to such holder a like certificate setting forth (i) such adjustment and readjustment, (ii) the Series A Conversion Price at the time in effect, and (iii) the number of shares of Common Stock and the amount, if any, of other property which at the time would be received upon the conversion of a share of Series A Preferred Stock. (10) RESERVATION OF STOCK ISSUABLE UPON CONVERSION. The Corporation shall at all times reserve and keep available out of its authorized but unissued shares of Common Stock, solely for the purpose of effecting the conversion of the shares of the Series A Preferred Stock, such number of its shares of Common Stock that shall from time to time be sufficient to effect the conversion of all outstanding shares of the Series A Preferred Stock; and if at any time the number of authorized but unissued shares of Common Stock not otherwise reserved for issuance shall not be sufficient to effect the conversion of all then outstanding shares of the Series A Preferred Stock, in addition to such other remedies as shall be available to the holders of such Series A Preferred Stock, the Corporation will take such corporate action that may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of Common Stock to such number of shares as shall be sufficient for such purposes, including without limitation, engaging in best efforts to obtain the requisite shareholder approval of any necessary amendment to its Certificate of Incorporation. (11) NOTICES. Any notice required by the provisions hereof to be given to the holders of shares of Series A Preferred Stock shall be deemed given on the date of service if served personally on the party to whom notice is to be given, or on the date of transmittal of services by facsimile transmission to the party to whom notice is to be given, and addressed to each holder of record at his address appearing on the books of the Corporation. (12) VOTING RIGHTS. Subject to Section 13 below, holders of Series A Preferred Stock shall not be entitled to vote, including with respect to the election of directors of the Corporation. (13) PROTECTIVE PROVISIONS. Subject to the rights of any series of preferred stock that exist or may from time to time come into existence, so long as any shares of Series A Preferred Stock are outstanding, the Corporation shall not without first obtaining the approval (by vote or written consent, as provided by law) of the holders of at least a majority of the then-outstanding shares of Series A Preferred Stock, voting separately as a series: a) amend its Certificate of Incorporation so as to affect adversely the shares of Series A Preferred Stock or any holder thereof (including by creating any additional classes or series of preferred stock with a liquidation preference or other rights senior to the Series A Preferred Stock); or b) change the rights of the holders of the holders of the Series A Preferred Stock in any other respect. (14) STATUS OF CONVERTED STOCK. In the event any shares of Series A Preferred Stock shall be converted pursuant to Section 4 or exchanged pursuant to Section 5 hereof, the shares so converted or exchanged shall be canceled and shall not be reissuable by the Corporation. The Certificate of Incorporation of the Corporation shall be appropriately amended to effect the corresponding reduction in the Corporation's authorized capital stock." (15) TERM. In the event that the Series A Preferred Stock shall not have been converted into shares of Common Stock or exchanged, as provided in Section 5 above, on or prior to the date that is the later of (A) six years after the date hereof and (B) the Exchange Termination Date, the Series A Preferred Stock shall either, at the option of the Corporation, (i) remain outstanding or (ii) be repaid in amount equal to the Series A Liquidation Preference plus accrued dividends thereon, in cash or by the issuance of shares at the Corporation's Common Stock based on the then-current Conversion Price. C. SERIES B CONVERTIBLE PREFERRED STOCK. All cross-references in each subparagraph of this Section C of Article IV refer to other subparagraphs in this Section C of Article IV unless otherwise indicated. (1) DESIGNATION. 25,000 shares of Preferred Stock shall be designated and known as the "Series B Preferred Stock." Such number of shares may be increased or decreased by resolution of the Board of Directors of the Corporation after obtaining the consent of a majority in interest of the holder(s) of the then-outstanding shares of Series B Preferred Stock; PROVIDED, that no decrease shall reduce the number of shares of Series B Preferred Stock to a number less than the number of shares then outstanding plus the number of such shares issuable upon exercise of outstanding rights, options or warrants or upon conversion of outstanding securities issued by the Corporation. (2) DIVIDEND PROVISIONS. Each share of Series B Preferred Stock, for a period of six years from the date of first issuance of the Series B Preferred Stock, shall be entitled to receive a mandatory dividend equal to 12.0% per year of the Original Issue Price (as defined below) thereof. Such dividend shall (1) shall compound on a semi- annual basis, the first compounding to commence six months from the date hereof, and (2) be payable semi-annually on each succeeding six and 12-month anniversary of the first issuance, solely by the issuance of additional shares of Series B Preferred Stock, at a price per share equal to the Original Issue Price thereof, and not in cash. Fractional shares of Series B Preferred Stock shall be issuable for purposes hereunder. (3) SENIORITY; LIQUIDATION PREFERENCE a) The Series B Preferred Stock, as to its liquidation preference, shall rank senior to or pari passu with any existing or future class or series of Preferred Stock issued by the Company; pari passu with the Series A Preferred Stock; and senior to the Company's Common Stock. b) In the event of any Liquidation (as defined in Section B of Article IV hereof), before any payment of cash or distribution of other property shall be made to the holders of the Common Stock or any other class or series of stock subordinate in liquidation preference to the Series B Preferred Stock, the holders of the Series A Preferred Stock and Series B Preferred Stock, on a pro rata basis based on their aggregate liquidation preferences then outstanding shall be entitled to receive out of the assets of the Corporation legally available for distribution to its shareholders, the Original Issue Price per share (as appropriately adjusted for any combinations or divisions or similar recapitalizations affecting the Series B Preferred Stock after issuance) and accrued and unpaid dividends thereon (the "Series B Liquidation Preference"). As used herein, the "Original Issue Price" per share is $1,000. c) If, upon any Liquidation, the assets of the Corporation available for distribution to its shareholders shall be insufficient to pay the holders of the Series A Preferred Stock and Series B Preferred Stock the full amounts to which they shall be entitled, the holders of the Series A Preferred Stock and Series B Preferred Stock shall share ratably (based on their respective outstanding aggregate liquidation preferences) in any distribution of assets in proportion to the respective amounts which would be payable to them in respect of the shares held by them if all amounts payable to them in respect of such were paid in full pursuant to Section 3(b). d) After the distributions described in Section 3(c) above have been paid, subject to the rights of other series of preferred stock that exist or may from time to time come into existence, the remaining assets of the Corporation available for distribution to shareholders shall be distributed among the holders of Common Stock pro rata based on the number of shares of Common Stock held by each. (4) CONVERSION. The holders of the Series B Preferred Stock shall have conversion rights (the "Series B Conversion Right"), through and including the date that is six years after the first issuance of any shares of Series B Preferred Stock (the "Conversion Termination Date"). a) Right to Convert. (1) Each share of Series B Preferred Stock shall be convertible, at the option of the holder thereof, at any time, at the office of the Corporation or any transfer agent for such stock, into such number of fully paid and non-assessable shares of Common Stock as is determined by dividing (x) the sum of the Original Issue Price of such share of Series B Preferred Stock and all accrued and unpaid dividends thereon by (y) the Series B Conversion Price (as defined below). The "Series B Conversion Price" shall for each issue of Series B Preferred Stock be a price equal to 150% of the average closing price of the Common Stock for the 60 trading days prior to the date of written notice of such purchase request of the Company for the purchase of such issue of Series B Preferred Stock. (2) Before any holder of Series B Preferred Stock shall be entitled to convert such shares into shares of Common Stock, such holder shall surrender the certificate or certificates therefor, duly endorsed, at the office of the Corporation or of any transfer agent for the Series B Preferred Stock, and shall give written notice to the Corporation at its principal corporate office, of the election to convert the same and shall state therein the name or names in which the certificate or certificates for shares of Common Stock are to be issued. The Corporation shall, as soon as practicable thereafter, issue and deliver at such office to such holder of Series B Preferred Stock, or to the nominee or nominees of such holder, a certificate or certificates for the number of shares of Common Stock to which such holder shall be entitled as set forth above. Such conversion shall be deemed to have been made immediately prior to the close of business on the date of such surrender of the shares of Series B Preferred Stock to be converted, and the person or persons entitled to receive the shares of Common Stock issuable upon such conversion shall be treated for all purposes as the record holder or holders of such shares of Common Stock as of such date. (3) In the event the Corporation should at any time fix a record date for the effectuation of a split or subdivision of the outstanding shares of Common Stock or the determination of holders of Common Stock entitled to receive a dividend or other distribution payable in additional shares of Common Stock or Common Stock Equivalents without payment of any consideration by such holder for the additional shares of Common Stock or the Common Stock Equivalents (including the additional shares of Common Stock issuable upon conversion or exercise thereof) or with payment that is less than the Series B Conversion Price then in effect, then, as of such record date (or the date of such dividend distribution, split or subdivision if no record date is fixed), the Series B Conversion Price of the Series B Preferred Stock shall be appropriately decreased so that the number of shares of Common Stock issuable on conversion of each share of such series shall be increased in proportion to such increase of the aggregate of (a) shares of Common Stock outstanding and (b) those issuable with respect to such Common Stock Equivalents, with the number of shares issuable with respect to Common Stock Equivalents determined from time to time as provided in Section 4(a)(5) below. (4) If the number of shares of Common Stock outstanding at any time is decreased by a combination of the outstanding shares of Common Stock, then, following the record date of such combination, the Series B Conversion Price for the Series B Preferred Stock shall be appropriately increased so that the number of shares of Common Stock issuable on conversion of each share of such series shall be decreased in proportion to such decrease in outstanding shares. (5) The following provisions shall apply for purposes of this Section 4(a): (a) The aggregate maximum number of shares of Common Stock deliverable upon conversion or exercise of Common Stock Equivalents (assuming the satisfaction of any conditions to convertibility or exercisability, including, without limitation, the passage of time, but without taking into account potential antidilution adjustments) shall be deemed to have been issued at the time such Common Stock Equivalents were issued. (b) In the event of any change in the number of shares of Common Stock deliverable or in the consideration payable to the Corporation upon conversion or exercise of such Common Stock Equivalents including, but not limited to, a change resulting from the antidilution provisions thereof, the Series B Conversion Price of the Series B Preferred Stock, to the extent in any way affected by or computed using such Common Stock Equivalents, shall be recomputed to reflect such change, but no further adjustment shall be made for the actual issuance of Common Stock or any payment of such consideration upon the exercise of any such options or rights or the conversion or exchange of such securities. (c) Upon the termination or expiration of the convertibility or exercisability of any such Common Stock Equivalents, the Series B Conversion Price of the Series B Preferred Stock, to the extent in any way affected by or computed using such Common Stock Equivalents, shall be recomputed to reflect the issuance of only the number of shares of Common Stock (and Common Stock Equivalents which remain convertible or exercisable) actually issued upon the conversion or exercise of such Common Stock Equivalents. (5) EXCHANGE RIGHT. In the event that EIS (as defined in Section B of Article IV hereof) shall have exercised the Exchange Right (as defined in Section B of Article IV hereof), EIS shall, at its option, within 30 days thereof, (i) cause to be paid to the Corporation, an amount equal to 30.1% of the aggregate amount of the Development Funding (as such term is defined in the Funding Agreement, dated as of January 7th, 2000, among EIS, Newco, EPIL, the Corporation and Elan (as such terms are defined in Section B of Article IV hereof) to date provided by each of the parties Newco), in accordance with the terms of the Funding Agreement, including any accrued and unpaid interest and/or dividends paid to EIS thereon, from and after the date hereof and until the date of such exercise, or (ii) surrender for cancellation, including any accrued and unpaid interest and/or dividends thereon paid to EIS, a portion of each issuance of Series B Preferred Stock having an aggregate Original Issue Price equal to 30.1% of the total amount of Development Funding provided by each of the parties to Newco, in accordance with the terms of the Funding Agreement in connection with the issuance of such Series B Preferred Stock, from and after the date hereof and until the date of the exercise of the Exchange Right, against the outstanding Series B Preferred Stock, if any, and/or the convertible promissory note dated as of January, 2000 by the Corporation in favor of EIS in the original principal amount of $12.015 million or (iii) effect a combination of (i) and (ii) above if applicable. (6) OTHER DISTRIBUTIONS. On or prior to the Conversion Termination Date, in the event the Corporation shall declare a distribution payable in securities of other persons, evidences of indebtedness issued by the Corporation or other persons, assets (excluding cash dividends) or options or rights not referred to in Section 4, then, in each such case for the purpose of this Section 6, the holders of the Series B Preferred Stock shall be entitled to a proportionate share of any such distribution as though they were the holders of the number of shares of Common Stock of the Corporation into which their shares of Series B Preferred Stock would be convertible as of the record date fixed for the determination of the holders of Common Stock of the Corporation entitled to receive such distribution. (7) RECAPITALIZATIONS. On or prior to the Conversion Termination Date, if at any time or from time to time there shall be a recapitalization of the Common Stock (other than a subdivision, combination or merger or sale of assets provided for in Section 3 or Section 4 hereof) provision shall be made so that the holders of the Series B Preferred Stock shall thereafter be entitled to receive upon conversion of the Series B Preferred Stock the number of shares of stock or other securities or property of the Corporation or otherwise, to which a holder of Common Stock deliverable upon conversion would have been entitled on such recapitalization. In any such case, appropriate adjustment shall be made in the application of the provisions of Section 4 with respect to the rights of the holders of the Series B Preferred Stock after the recapitalization to the end that the provisions of Section 4 (including adjustment of the Series B Conversion Price then in effect and the number of shares purchasable upon conversion of the Series B Preferred Stock) shall be applicable after that event as nearly equivalent as may be practicable. (8) NO IMPAIRMENT. The Corporation will not, by amendment of its Certificate of Incorporation or through any reorganization, recapitalization, transfer of assets, consolidation, merger, dissolution, issuance or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Corporation, but will at all times in good faith assist in the carrying out of all the provisions hereof and in the taking of all such action as may be necessary or appropriate in order to protect the Series B Conversion Rights and Exchange Right of the holders of the Series B Preferred Stock against impairment. (9) NO FRACTIONAL SHARES AND CERTIFICATE AS TO ADJUSTMENTS. a) No fractional shares shall be issued upon the conversion of any share or shares of the Series B Preferred Stock, and the number of shares of Common Stock to be issued shall be rounded to the nearest whole share. Whether or not fractional shares are issuable upon such conversion shall be determined on the basis of the aggregate number of shares of Series B Preferred Stock each holder is at the time converting into Common Stock and the aggregate number of shares of Common Stock issuable to each such holder upon such conversion. b) Upon the occurrence of each adjustment or readjustment of the Series B Conversion Price pursuant to Section 4, the Corporation, at its expense, shall promptly compute such adjustment or readjustment in accordance with the terms hereof and prepare and furnish to each holder of shares of Series B Preferred Stock a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based. The Corporation shall, upon the written request at any time of any holder of Series B Preferred Stock, furnish or cause to be furnished to such holder a like certificate setting forth (i) such adjustment and readjustment, (ii) the Series B Conversion Price at the time in effect, and (iii) the number of shares of Common Stock and the amount, if any, of other property which at the time would be received upon the conversion of a share of Series B Preferred Stock. (10) RESERVATION OF STOCK ISSUABLE UPON CONVERSION. The Corporation shall at all times reserve and keep available out of its authorized but unissued shares of Common Stock, solely for the purpose of effecting the conversion of the shares of the Series B Preferred Stock, such number of its shares of Common Stock that shall from time to time be sufficient to effect the conversion of all outstanding shares of the Series B Preferred Stock; and if at any time the number of authorized but unissued shares of Common Stock not otherwise reserved for issuance shall not be sufficient to effect the conversion of all then outstanding shares of the Series B Preferred Stock, in addition to such other remedies as shall be available to the holders of such Series B Preferred Stock, the Corporation will take such corporate action that may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of Common Stock to such number of shares as shall be sufficient for such purposes, including without limitation, engaging in best efforts to obtain the requisite shareholder approval of any necessary amendment to its Certificate of Incorporation. (11) NOTICES. Any notice required by the provisions hereof to be given to the holders of shares of Series B Preferred Stock shall be deemed given on the date of service if served personally on the party to whom notice is to be given, or on the date of transmittal of services by facsimile transmission to the party to whom notice is to be given, and addressed to each holder of record at his address appearing on the books of the Corporation. (12) REPURCHASES OR REDEMPTIONS OF THE SERIES B PREFERRED STOCK. (a) The Series B Preferred Stock shall be redeemable, in whole or in part (in increments of at least $250,000), at the option of the Corporation for cash at 100% of the Original Issue Price plus accrued dividends (the "Redemption Price"), so long as all of the amounts provided to be funded as set forth in the Securities Purchase Agreement, dated as of January 7th, 2000, between EIS and the Corporation, have been funded or the Corporation has waived its right to any additional funding. Any shares of Series B Preferred Stock called for redemption shall no longer be entitled to the Conversion Right. (b) The Corporation shall notify the holders of the Series B Preferred Stock in writing setting forth (a) the terms of the redemption of the Series B Preferred Stock, and (b) the proposed date for such redemption (the "Redemption Date"), which shall be between 10 and 30 days after the date of such notice. On the Redemption Date, (x) the Corporation shall pay in cash an amount equal to the Redemption Price to the holders of the Series B Preferred Stock by check or wire transfer to an account designated by such holders, and (y) the holders shall tender their shares of Series B Preferred Stock, subject to the redemption, to the Corporation, for cancellation. The holders and the Corporation shall take all other necessary or appropriate actions in connection with or to effect such closing. (13) VOTING RIGHTS. Subject to Section 14 below, holders of Series B Preferred Stock shall not be entitled to vote, including with respect to the election of directors of the Corporation. (14) PROTECTIVE PROVISIONS. Subject to the rights of any series of preferred stock that exist or may from time to time come into existence, so long as any shares of Series B Preferred Stock are outstanding, the Corporation shall not without first obtaining the approval (by vote or written consent, as provided by law) of the holders of at least a majority of the then-outstanding shares of Series B Preferred Stock, voting separately as a series: a) amend its Certificate of Incorporation so as to affect adversely the shares of Series B Preferred Stock or any holder thereof (including by creating any additional classes or series of preferred stock with a liquidation preference or other rights senior to with the Series B Preferred Stock); or b) change the rights of the holders of the holders of the Series B Preferred Stock in any other respect. (15) STATUS OF CONVERTED STOCK. In the event any shares of Series B Preferred Stock shall be converted pursuant to Section 4, the shares so converted or exchanged shall be canceled and shall not be reissuable by the Corporation. The Certificate of Incorporation of the Corporation shall be appropriately amended to effect the corresponding reduction in the Corporation's authorized capital stock." (16) TERM. In the event that the Series B Preferred Stock shall not have been converted into shares of Common Stock or exchanged, as provided in Section 5 above, on or prior to the date that is the later of (A) six years after the date hereof and (B) the Exchange Termination Date, the Series B Preferred Stock shall either, at the option of the Corporation, (i) remain outstanding or (ii) be repaid in amount equal to the Series B Liquidation Preference plus accrued dividends thereon, in cash or by the issuance of shares at the Corporation's Common Stock based on the then-current Conversion Price. V. A. REVERSE STOCK SPLIT (1) Effective 12:01 a.m. on [__________, 2003] (the "Effective Time") each one (1) share of Common Stock of the Corporation issued and outstanding immediately prior to the Effective Time ("Old Common Stock") shall automatically be combined, without any action on the part of the holder thereof, into [_____] of one share of fully paid and nonassessable Common Stock of the Corporation ("New Common Stock"), subject to the treatment of fractional shares described below. (2) Following the Effective Time, each holder of Old Common Stock shall be entitled to receive upon surrender of such holder's certificate(s) representing Old Common Stock (whether one or more, "Old Certificates") for cancellation pursuant to procedures adopted by the Corporation, a certificate(s) representing the number of whole shares of New Common Stock (whether one or more, "New Certificates") into which and for which the shares of Old Common Stock formerly represented by such Old Certificates so surrendered are reclassified under the terms hereof. From and after the Effective Time, Old Certificates shall represent only the right to receive New Certificates and, where applicable, cash in lieu of fractional shares, as provided below. (3) No fractional shares of New Common Stock of the Corporation shall be issued. No stockholder of the Corporation shall transfer any fractional shares of Common Stock of the Corporation. The Corporation shall not recognize on its stock record books any purported transfer of any fractional share of Common Stock of the Corporation. A holder of Old Certificates at the Effective Time who would otherwise be entitled to a fraction of a share of New Common Stock shall, in lieu thereof, be entitled to receive a cash payment in an amount equal to the fraction to which the stockholder would otherwise be entitled multiplied by the per share closing sales price of the Common Stock on the day immediately prior to the Effective Time, as reported on the Nasdaq National Market (or if such price is not available, then such other price as determined by the board of directors). VI. MANAGEMENT. For the management of the business and for the conduct of the affairs of the Corporation, and in further definition, limitation and regulation of the powers of the Corporation, of its directors and of its stockholders or any class thereof, as the case may be, it is further provided that: A. BOARD OF DIRECTORS (1) The management of the business and the conduct of the affairs of the Corporation shall be vested in its Board of Directors. The number of directors which shall constitute the whole Board of Directors shall be designated in the Amended and Restated Bylaws of the Corporation (the "Bylaws"). The directors shall be divided into three classes with the term of office of the first class (Class I) to expire at the annual meeting of stockholders held in 2004; the term of office of the second class (Class II) to expire at the annual meeting of stockholders held in 2005; the term of office of the third class (Class III) to expire at the annual meeting of stockholders held in 2006; and thereafter for each such term to expire at each third succeeding annual meeting of stockholders after such election. (2) Subject to the rights of the holders of any series of Preferred Stock to elect additional directors under specified circumstances, directors shall be elected at each annual meeting of stockholders for a term of one year. Each director shall serve until his successor is duly elected and qualified or until his death, resignation or removal. No decrease in the number of directors constituting the Board of Directors shall shorten the term of any incumbent director. (3) Elections of directors need not be by written ballot unless the Bylaws of the Corporation shall so provide.

SECTION 3. ADMINISTRATION 3.1 AUTHORITY OF COMMITTEE. The Plan shall be administered by the Committee, which shall be appointed by and serve at the pleasure of the Board; provided, however, with respect to Options to Outside Directors, all references in the Plan to the Committee shall be deemed to be references to the Board. Subject to the terms of the Plan and applicable law, and in addition to other express powers and authorizations conferred on the Committee by the Plan, the Committee shall have full power and authority in its discretion to: (i) designate Participants; (ii) determine the type or types of Options to be granted to a Participant; (iii) determine the number of Shares to be covered by, or with respect to which payments, rights, or other matters are to be calculated in connection with Options; (iv) determine the timing, terms, and conditions of any Option; (v) accelerate the time at which all or any part of an Option may be settled or exercised; (vi) determine whether, to what extent, and under what circumstances Options may be settled or exercised in cash, Shares, other securities, other Options or other property, or canceled, forfeited, or suspended and the method or methods by which Options may be settled, exercised, canceled, forfeited, or suspended; (vii) determine whether, to what extent, and under what circumstances cash, Shares, other securities, other Options, other property, and other amounts payable with respect to an Option shall be deferred either automatically or at the election of the holder thereof or of the Committee; (viii) interpret and administer the Plan and any instrument or agreement relating to, or Option made under, the Plan; (ix) amend or modify the terms of any Option at or after grant (with the consent of the holder of the Option if adversely affected); (x) establish, amend, suspend, or waive such rules and regulations and appoint such agents as it shall deem appropriate for the proper administration of the Plan; and (xi) make any other determination and take any other action that the Committee deems necessary or desirable for the administration of the Plan, subject to the exclusive authority of the Board under Section 10 hereunder to amend or terminate the Plan. 3.2 COMMITTEE DISCRETION BINDING. Unless otherwise expressly provided in the Plan, all designations, determinations, interpretations, and other decisions under or with respect to the Plan or any Option shall be within the sole discretion of the Committee, may be made at any time and shall be final, conclusive, and binding upon all Persons, including the Company, any Subsidiary or Affiliate, any Participant and any holder or beneficiary of any Option. 3.3 ACTION BY THE COMMITTEE. The Committee shall select one of its members as its Chairperson and shall hold its meetings at such times and places and in such manner as it may determine. A majority of its members shall constitute a quorum. All determinations of the Committee shall be made by not less than a majority of its members. Any decision or determination reduced to writing and signed by all of the members of the Committee shall be fully effective as if it had been made by a majority vote at a meeting duly called and held. The exercise of an Option or receipt of an Option shall be effective only if an Option Agreement shall have been duly executed and delivered on behalf of the Company following the grant of the Option or other Option. The Committee may appoint a Secretary and may make such rules and regulations for the conduct of its business, as it shall deem advisable. 3.4 DELEGATION. Subject to the terms of the Plan and applicable law, the Committee may delegate to one or more officers or managers of the Company or of any Subsidiary or Affiliate, or to a Committee of such officers or managers, the authority, subject to such terms and limitations as the Committee shall determine, to grant Options to, or to cancel, modify or waive rights with respect to, or to alter, discontinue, suspend, or terminate Options held by Participants who are not officers or directors of the Company for purposes of Section 16 or who are otherwise not subject to such Section. 3.5 NO LIABILITY. No member of the Board or Committee shall be liable for any action taken or determination made in good faith with respect to the Plan or any Option granted hereunder. SECTION 4. SHARES AVAILABLE FOR OPTIONS 4.1 SHARES AVAILABLE. Subject to the provisions of Section 4.2 hereof, the stock to be subject to Options under the Plan shall be the Shares of the Company and the maximum number of Shares with respect to which Options may be granted under the Plan shall be 39,309,224 (which includes 2,309,224 Shares which are subject to outstanding Options or available for future grants under the Company's 1996 Stock Option Plan (the "1996 Plan")). The maximum number of Shares which may be the subject of Options granted during any calendar year to any individual shall not exceed 12,000,000 Shares (subject to adjustment under Section 4.2 hereof consistent with Section 162(m) of the Code). If the Shares that would be issued or transferred pursuant to any Options are not issued or transferred and cease to be issuable or transferable for any reason, the number of Shares subject to such Option will no longer be charged against the limitation provided for herein and may again be made subject to Options. Notwithstanding the preceding, with respect to any Option granted to any individual who is a "covered employee" within the meaning of Section 162(m) of the Code that is cancelled, the number of shares subject to such Option shall continue to count against the maximum number of Shares which may be the subject of Options granted to such individual. For purposes of the preceding sentence, if, after grant, the exercise price of an Option is reduced, such reduction shall be treated as a cancellation of such Option and the grant of a new Option, and both the cancellation of the Option and the new Option shall reduce the maximum number of Shares for which Options may be granted to the holder of such Option. 4.2 ADJUSTMENTS. If, prior to the complete exercise of any Option, there shall be declared and paid a stock dividend upon the Shares or if the Shares shall be split up, converted, exchanged, reclassified, or in any way substituted for, then the Option, to the extent that it has not been exercised, shall entitle the holder thereof upon the future exercise of the Option to such number and kind of securities or cash or other property subject to the terms of the Option to which he would have been entitled had he actually owned the Shares subject to the unexercised portion of the Option at the time of the occurrence of such stock dividend, split-up, conversion, exchange, reclassification or substitution, and the aggregate purchase price upon the future exercise of the Option shall be the same as if the originally optioned Shares were being purchased thereunder. Any fractional shares or securities issuable upon the exercise of the Option as a result of such adjustment shall be payable in cash based upon the Fair Market Value of such shares or securities at the time of the exercise. If any such event should occur, the number of Shares with respect to which Options remain to be issued, or with respect to which Options may be reissued (including, in each case, Options to be granted to any individual during any calendar year), shall be adjusted in a similar manner. In the event of any other change in the corporate structure or outstanding Shares such that an adjustment is determined by the Committee, in its sole discretion, to be appropriate, then the Committee shall, in such manner as it may deem equitable (and, with respect to Incentive Stock Options, in such manner as is consistent with Section 422 of the Code and the regulations thereunder): (i) adjust any or all of (1) the aggregate number of Shares or other securities of the Company (or number and kind of other securities or property) with respect to which Options may be granted under the Plan; (2) the number of Shares or other securities of the Company (or number and kind of other securities or property) subject to outstanding Options under the Plan; and (3) the grant or exercise price with respect to any Option under the Plan, provided that the number of shares subject to any Option shall always be a whole number; (ii) if deemed appropriate, provide for an equivalent Option in respect of securities of the surviving entity of any merger, consolidation or other transaction or event having a similar effect; or (iii) if deemed appropriate, make provision for a cash payment to the holder of an outstanding Option. 4.3 SUBSTITUTE OPTIONS. Any Shares issued by the Company as Substitute Options in connection with the assumption or substitution of outstanding grants from any acquired corporation shall not reduce the Shares available for Options under the Plan if the original stockholder approval in connection with such outstanding grants (or approval by the Company's stockholders of the relevant transaction) is such that it will continue to apply to the Substitute Options without requiring further approval by stockholders of the Company. If such original stockholder approval (or approval of the transaction) will not continue to apply to the Substitute Options, then any Shares issued pursuant to such Substitute Options shall reduce the Shares available for Options under the Plan. 4.4 SOURCES OF SHARES DELIVERABLE UNDER OPTIONS. Any Shares delivered pursuant to an Option may consist, in whole or in part, of authorized and unissued Shares or of issued Shares that have been reacquired by the Company. SECTION 5. ELIGIBILITY Any Employee, Director or Consultant shall be eligible to be designated a Participant; provided, however, that Non-Employee Directors and Outside Directors shall only be eligible to receive Options granted consistent with Section 7. SECTION 6. STOCK OPTIONS 6.1 GRANT. Subject to the provisions of the Plan, the Committee shall have sole and complete authority to determine the Participants to whom Options shall be granted, the number of Shares subject to each Option, the exercise price and the conditions and limitations applicable to the exercise of each Option. The Committee shall have the authority to grant Incentive Stock Options, or to grant Non-Qualified Stock Options, or to grant both types of Options; provided, however, that an Incentive Stock Option may only be granted to a person who at the time of grant is an Employee of the Company or a Subsidiary. In the case of Incentive Stock Options, the terms and conditions of such grants shall be subject to and comply with such rules as may be prescribed by Section 422 of the Code, as from time to time amended, and any regulations implementing such statute. A person who has been granted an Option under this Plan may be granted additional Options under the Plan if the Committee shall so determine; provided, however, that to the extent the aggregate Fair Market Value (determined at the time the Incentive Stock Option related thereto is granted) of the Shares with respect to which all Incentive Stock Options are exercisable for the first time by an Employee during any calendar year (under all plans described in subsection (d) of Section 422 of the Code of the Company and its Subsidiaries) exceeds $100,000 (or such higher amount as is permitted in the future under Section 422(d) of the Code), such Options shall be treated as Non-Qualified Stock Options. 6.2 PRICE. The Committee in its sole discretion shall establish the Option Price at the time each Option is granted. Except in the case of Substitute Options, the Option Price of an Option which is intended to be an Incentive Stock Option may not be less than 100% of the Fair Market Value of the Shares with respect to which the Option is granted on the date of grant of such Option. 6.3 TERM. Subject to the Committee's authority under Section 3.1 and the provisions of Section 6.5, each Option and all rights and obligations thereunder shall expire on the date determined by the Committee and specified in the Option Agreement. The Committee shall be under no duty to provide terms of like duration for Options granted under the Plan. Notwithstanding the foregoing, no Option shall be exercisable after the expiration of ten (10) years from the date such Option was granted. 6.4 EXERCISE. (a) Each Option shall be exercisable at such times and subject to such terms and conditions as the Committee may, in its sole discretion, specify in the applicable Option Agreement or thereafter. The Committee shall have full and complete authority to determine, subject to Section 6.5 herein, whether an Option will be exercisable in full at any time or from time to time during the tern of the Option, or to provide for the exercise thereof in such installments, upon the occurrence of such events and at such times during the term of the Option as the Committee may determine. (b) The Committee may impose such conditions with respect to the exercise of Options, including without limitation, any relating to the application of federal, state or foreign securities laws or the Code, as it may deem necessary or advisable. The exercise of any Option granted hereunder shall be effective only at such time as the sale of Shares pursuant to such exercise will not violate any state or federal securities or other laws. (c) An Option may be exercised in whole or in part at any time, with respect to whole Shares only, within the period permitted thereunder for the exercise thereof, and shall be exercised by written notice of intent to exercise the Option, delivered to the Company at its principal office, and payment in full to the Company at the direction of the Committee of the amount of the Option Price for the number of Shares with respect to which the Option is then being exercised. The exercise of an Option shall result in the termination of the other to the extent of the number of Shares with respect to which the Option is exercised. (d) Payment of the Option Price shall be made in cash or cash equivalents, or, at the discretion of the Committee, (i) in whole Shares having a Fair Market Value on the date of exercise (or next succeeding trading date, if the date of exercise is not a trading date) equal to the aggregate Option Price, together with any applicable withholding taxes, or (ii) by a combination of such cash (or cash equivalents) and such Shares; provided, however, that the optionee shall not be entitled to tender Shares which have not been beneficially owned by the optionee for at least six months. Subject to applicable securities laws, an Option may also be exercised by delivering a notice of exercise of the Option and simultaneously selling the Shares thereby acquired, pursuant to a brokerage or similar agreement approved in advance by proper officers of the Company, using the proceeds of such sale as payment of the Option Price, together with any applicable withholding taxes. Until the optionee has been issued the Shares subject to such exercise, he or she shall possess no rights as a stockholder with respect to such Shares. 6.5 TEN PERCENT STOCK RULE. Notwithstanding any other provisions in the Plan, if at the time an Option is otherwise to be granted pursuant to the Plan the optionee owns directly or indirectly (within the meaning of Section 424(d) of the Code) Shares of the Company possessing more than ten percent (10%) of the total combined voting power of all classes of Stock of the Company or its parent or Subsidiary or Affiliate corporations (within the meaning of Section 422 (b) (6) of the Code), then any Incentive Stock Option to be granted to such optionee pursuant to the Plan shall satisfy the requirement of Section 422(c) (5) of the Code, and the Option Price shall be not less than 110% of the Fair Market Value of the Shares of the Company on the date such Option is granted, and such Option by its terms shall not be exercisable after the expiration of five (5) years from the date such Option is granted. 6.6 OPTIONS GRANTED UNDER 1996 PLAN. The Plan shall cover all Options granted under the 1996 Plan which are outstanding on the effective date described in Section 12.1. Such Options shall continue to be subject to the same terms and conditions as were applicable to such Options pursuant to the 1996 Plan and the Option Agreements executed thereunder. SECTION 7. NON-EMPLOYEE DIRECTOR AND OUTSIDE DIRECTOR OPTIONS The Board may provide that all or a portion of a Non-Employee Director's and/or Outside Director's annual retainer, meeting fees and/or other Options or compensation as determined by the Board, be payable (either automatically or at the election of a Non-Employee Director or Outside Director) in the form of Non-Qualified Stock Options. The Board shall determine the terms and conditions of any such Options, including the terms and conditions which shall apply upon a termination of the Non-Employee Director's or Outside Director's service as a member of the Board, and shall have full power and authority in its discretion to administer such Options, subject to the terms of the Plan and applicable law. With respect to such Options, all references in the Plan to the Committee shall be deemed to be references to the Board. SECTION 8. TERMINATION OF EMPLOYMENT OR SERVICE The Committee shall have the full power and authority to determine the terms and conditions that shall apply to any Option upon a termination of employment or service with the Company, its Subsidiaries and Affiliates, including a termination by the Company with or without cause, by a Participant voluntarily, or by reason of death, Disability or Retirement, and may provide such terms and conditions in the Option Agreement or in such rules and regulations as it may prescribe. Notwithstanding the preceding, if and to the extent that any Option which is intended to be an Incentive Stock Option is exercised more than three months after the Participant's termination of employment with the Company and its Subsidiaries other than due to death or Disability, or more than twelve months after the Participant's termination of employment with the Company and its Subsidiaries due to Disability, such Option shall be treated as a Non-Qualified Stock Option. Unless otherwise determined by the Committee at the time of grant, in the case of any Option granted to an Employee, a change in the status of such Employee to that of a Consultant shall be treated as a termination of employment and service for purposes of such Option and the Plan; provided, however, that the Committee may in its sole discretion, at the time of such termination, determine that all or a portion of such Option may continue to vest during the holder's service as a Consultant and may remain exercisable for such period as may be determined by the Committee (but not longer than ten years after the date of grant of the Option if, at the date of grant, the Option was intended to be an Incentive Stock Option). SECTION 9. CHANGE IN CONTROL Upon a Change in Control, to the extent permitted by applicable law: (i) any surviving or acquiring corporation shall assume any Options outstanding under the Plan or shall substitute similar Options (including an option to acquire the same consideration paid to the stockholders in the transaction) for those outstanding under the Plan, or (ii) such Options shall continue in full force and effect. In the event any surviving or acquiring corporation refuses to assume such Options, or to substitute similar options for those outstanding under the Plan, then, with respect to Options held by persons then performing services as Employees, Directors or Consultants, the time during which such Options may be exercised shall be accelerated prior to such event and the Options shall be terminated if not exercised after such acceleration and at or prior to such event. SECTION 10. AMENDMENT AND TERMINATION 10.1 AMENDMENTS TO THE PLAN. The Board may amend, alter, suspend, discontinue, or terminate the Plan or any portion thereof at any time; provided that no such amendment, alteration, suspension, discontinuation or termination shall be made without stockholder approval if such approval is necessary to comply with any tax or regulatory requirement for which or with which the Board deems it necessary or desirable to comply. 10.2 AMENDMENTS TO OPTIONS. Subject to the restrictions of Section 6.2, the Committee may waive any conditions or rights under, amend any terms of, or alter, suspend, discontinue, cancel or terminate, any Option theretofore granted, prospectively or retroactively; provided that any such waiver, amendment, alteration, suspension, discontinuance, cancellation or termination that would adversely affect the rights of any Participant or any holder or beneficiary of any Option theretofore granted shall not to that extent be effective without the consent of the affected Participant, holder, or beneficiary. 10.3 ADJUSTMENTS OF OPTIONS UPON THE OCCURRENCE OF CERTAIN UNUSUAL OR NONRECURRING EVENTS. The Committee is hereby authorized to make adjustments in the terms and conditions of, and the criteria included in, Options in recognition of unusual or nonrecurring events (including, without limitation, the events described in Section 4.2 hereof) affecting the Company, any Subsidiary or Affiliate, or the financial statements of the Company or any Subsidiary or Affiliate, or of changes in applicable laws, regulations, or accounting principles, whenever the Committee determines that such adjustments are appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan. SECTION 11. GENERAL PROVISIONS 11.1 LIMITED TRANSFERABILITY OF OPTIONS. Except as otherwise provided in the Plan, no Option shall be assigned, alienated, pledged, attached, sold or otherwise transferred or encumbered by a Participant, except by will or the laws of descent and distribution and/or as may be provided by the Committee in its discretion, at or after grant, in the Option Agreement. An Incentive Stock Option shall not be transferred other than by will or the laws of descent and distribution and, during the holder's lifetime, may only be exercised by the holder. No transfer of an Option by will or by laws of descent and distribution shall be effective to bind the Company unless the Company shall have been furnished with written notice thereof and an authenticated copy of the will and/or such other evidence as the Committee may deem necessary or appropriate to establish the validity of the transfer. 11.2 NO RIGHTS TO OPTIONS. No Person shall have any claim to be granted any Option, and there is no obligation for uniformity of treatment of Participants or holders or beneficiaries of Options. The terms and conditions of Options need not be the same with respect to each Participant. 11.3 SHARE CERTIFICATES. All certificates for Shares or other securities of the Company or any Subsidiary or Affiliate delivered under the Plan pursuant to any Option or the exercise thereof shall be subject to such stop transfer orders and other restrictions as the Committee may deem advisable under the Plan or the rules, regulations and other requirements of the SEC or any state securities commission or regulatory authority, any stock exchange or other market upon which such Shares or other securities are then listed, and any applicable Federal or state laws, and the Committee may cause a legend or legends to be put on any such certificates to make appropriate reference to such restrictions. 11.4 WITHHOLDING. A Participant may be required to pay to the Company or any Subsidiary or Affiliate and the Company or any Subsidiary or Affiliate shall have the right and is hereby authorized to withhold from any Option, from any payment due or transfer made under any Option or under the Plan, or from any compensation or other amount owing to a Participant the amount (in cash, Shares, other securities, other Options or other property) of any applicable withholding or other taxes in respect of an Option, its exercise, or any payment or transfer under an Option or under the Plan and to take such other action as may be necessary in the opinion of the Company to satisfy all obligations for the payment of such taxes. If withholding is satisfied by withholding Shares which would otherwise be issued pursuant to the exercise of an Option, then the Shares withheld shall have a Fair Market Value on the date on which such withholding is satisfied equal to the statutory minimum amount required to be withheld. 11.5 OPTION AGREEMENTS. Each Option hereunder shall be evidenced by an Option Agreement that shall be delivered to the Participant and may specify the terms and conditions of the Option and any rules applicable thereto. In the event of a conflict between the terms of the Plan and any Option Agreement, the terms of the Plan shall prevail. 11.6 NO LIMIT ON OTHER COMPENSATION ARRANGEMENTS. Nothing contained in the Plan shall prevent the Company or any Subsidiary or Affiliate from adopting or continuing in effect other compensation arrangements, which may, but need not, provide for the grant of Options. 11.7 NO RIGHT TO EMPLOYMENT. The grant of an Option shall not be construed as giving a Participant the right to be retained in the employ of the Company or any Subsidiary or Affiliate. Further, the Company or a Subsidiary or Affiliate may at any time dismiss a Participant from employment, free from any liability or any claim under the Plan, unless otherwise expressly provided in an Option Agreement. 11.8 NO RIGHTS AS STOCKHOLDER. Subject to the provisions of the Plan and the applicable Option Agreement, no Participant or holder or beneficiary of any Option shall have any rights as a stockholder with respect to any Shares to be distributed under the Plan until such person has become a holder of such Shares. 11.9 GOVERNING LAW. The validity, construction and effect of the Plan and any rules and regulations relating to the Plan and any Option Agreement shall be determined in accordance with the laws of the State of Colorado without giving effect to conflicts of laws principles. 11.10 SEVERABILITY. If any provision of the Plan or any Option Agreement is, or becomes, or is deemed to be invalid, illegal, or unenforceable in any jurisdiction or as to any Person or Option, or would disqualify the Plan or any Option under any law deemed applicable by the Committee, such provision shall be construed or deemed amended to conform to the applicable laws, or if it cannot be construed or deemed amended without, in the determination of the Committee, materially altering the intent of the Plan or the Option, such provision shall be stricken as to such jurisdiction, Person or Option and the remainder of the Plan and any such Option shall remain in full force and effect. 11.11 OTHER LAWS. The Committee may refuse to issue or transfer any Shares or other consideration under an Option if, acting in its sole discretion, it determines that the issuance or transfer of such Shares or such other consideration might violate any applicable law or regulation (including applicable non-U.S. laws or regulations) or entitle the Company to recover the same under Exchange Act Section 16 (b), and any payment tendered to the Company by a Participant, other holder or beneficiary in connection with the exercise of such Option shall be promptly refunded to the relevant Participant, holder, or beneficiary. 11.12 NO TRUST OR FUND CREATED. Neither the Plan nor any Option shall create or be construed to create a trust or separate fund of any kind or a fiduciary relationship between the Company or any Subsidiary or Affiliate and a Participant or any other Person. To the extent that any Person acquires a right to receive payments from the Company or any Subsidiary or Affiliate pursuant to an Option, such right shall be no greater than the right of any unsecured general creditor of the Company or any Subsidiary or Affiliate. 11.13 NO FRACTIONAL SHARES. No fractional Shares shall be issued or delivered pursuant to the Plan or any Option, and the Committee shall determine whether cash, other securities, or other property shall be paid or transferred in lieu of any fractional Shares or whether such fractional Shares or any rights thereto shall be canceled, terminated or otherwise eliminated. 11.14 HEADINGS. Headings are given to the sections and subsections of the Plan solely as a convenience to facilitate reference. Such headings shall not be deemed in any way material or relevant to the construction or interpretation of the Plan or any provision thereof. SECTION 12. TERM OF THE PLAN 12.1 EFFECTIVE DATE. This amendment and restatement of the Plan shall be effective as of February 4, 2003, provided it is approved and ratified by the Company's stockholders on or prior to February 3, 2004. If this amendment and restatement of the Plan is not so approved by the Company's stockholders, then any Options granted pursuant to the amended provisions of the Plan shall be void and of no further force or effect. 12.2 EXPIRATION DATE. No new Options shall be granted under the Plan after March 21, 2011. Unless otherwise expressly provided in the Plan or in an applicable Option Agreement, any Option granted hereunder may, and the authority of the Board or the Committee to amend, alter, adjust, suspend, discontinue, or terminate any such Option or to waive any conditions or rights under any such Option shall, continue after said expiration date. ANNEX D RIBOZYME PHARMACEUTICALS, INC. EMPLOYEE STOCK PURCHASE PLAN ADOPTED FEBRUARY 29, 1996, AMENDED AND RESTATED AS OF APRIL 30, 2001 1. PURPOSE. (a) The purpose of the Employee Stock Purchase Plan (the "Plan") is to provide a means by which employees of Ribozyme Pharmaceuticals, Inc., a Delaware corporation (the "Company"), and its Affiliates, as defined in subparagraph l(b), which are designated as provided in subparagraph 2(b), may be given an opportunity to purchase stock of the Company. (b) The word "Affiliate" as used in the Plan means any parent corporation or subsidiary corporation of the Company, as those terms are defined in Sections 424(e) and (f), respectively, of the Internal Revenue Code of 1986, as amended (the "Code"). (c) The Company, by means of the Plan, seeks to retain the services of its employees, to secure and retain the services of new employees, and to provide incentives for such persons to exert maximum efforts for the success of the Company. (d) The Company intends that the rights to purchase stock of the Company granted under the Plan be considered options issued under an "employee stock purchase plan" as that term is defined in Section 423(b) of the Code. 2. ADMINISTRATION. (a) The Plan shall be administered by the Board of Directors (the "Board") of the Company unless and until the Board delegates administration to a Committee, as provided in subparagraph 2(c). Whether or not the Board has delegated administration, the Board shall have the final power to determine all questions of policy and expediency that may arise in the administration of the Plan. (b) The Board shall have the power, subject to, and within the limitations of, the express provisions of the Plan: (i) To determine when and how rights to purchase stock of the Company shall be granted and the provisions of each offering of such rights (which need not be identical). (ii) To designate from time to time which Affiliates of the Company shall be eligible to participate in the Plan. (iii) To construe and interpret the Plan and rights granted under it, and to establish, amend and revoke rules and regulations for its administration. The Board, in the exercise of this power, may correct any defect, omission or inconsistency in the Plan, in a manner and to the extent it shall deem necessary or expedient to make the Plan fully effective. (iv) To amend the Plan as provided in paragraph 13. (v) Generally, to exercise such powers and to perform such acts as the Board deems necessary or expedient to promote the best interests of the Company and its Affiliates and to carry out the intent that the Plan be treated as an "employee stock purchase plan" within the meaning of Section 423 of the Code. (c) The Board may delegate administration of the Plan to a Committee composed of not fewer than two (2) members of the Board (the "Committee"). If administration is delegated to a Committee, the Committee shall have, in connection with the administration of the Plan, the powers theretofore possessed by the Board, subject, however, to such resolutions, not inconsistent with the provisions of the Plan, as may be adopted from time to time by the Board. The Board may abolish the Committee at any time and revest in the Board the administration of the Plan. 3. SHARES SUBJECT TO THE PLAN. (a) Subject to the provisions of paragraph 12 relating to adjustments upon changes in stock, the stock that may be sold pursuant to rights granted under the Plan shall not exceed in the aggregate 600,000 shares of the Company's common stock (the "Common Stock"). If any right granted under the Plan shall for any reason terminate without having been exercised, the Common Stock not purchased under such right shall again become available for the Plan. (b) The stock subject to the Plan may be unissued shares or reacquired shares, bought on the market or otherwise. 4. GRANT OF RIGHTS; OFFERING. The Board or the Committee may from time to time grant or provide for the grant of rights to purchase Common Stock of the Company under the Plan to eligible employees (an "Offering") on a date or dates (the "Offering Date(s)") selected by the Board or the Committee. Each Offering shall be in such form and shall contain such terms and conditions as the Board or the Committee shall deem appropriate, which shall comply with the requirements of Section 423(b)(5) of the Code that all employees granted rights to purchase stock under the Plan shall have the same rights and privileges. The terms and conditions of an Offering shall be incorporated by reference into the Plan and treated as part of the Plan. The provisions of separate Offerings need not be identical, but each Offering shall include (through incorporation of the provisions of this Plan by reference in the document comprising the Offering or otherwise) the period during which the Offering shall be effective, which period shall not exceed 27 months beginning with the Offering Date, and the substance of the provisions contained in paragraphs 5 through 8, inclusive. 5. ELIGIBILITY. (a) Rights may be granted only to employees of the Company or, as the Board or the Committee may designate as provided in subparagraph 2(b), to employees of any Affiliate of the Company. Except as provided in subparagraph 5(b), an employee of the Company or any Affiliate shall not be eligible to be granted rights under the Plan, unless, on the Offering Date, such employee has been in the employ of the Company or any Affiliate for such continuous period preceding such grant as the Board or the Committee may require, but in no event shall the required period of continuous employment be greater than two (2) years. In addition, unless otherwise determined by the Board or the Committee and set forth in the terms of the applicable Offering, no employee of the Company or any Affiliate shall be eligible to be granted rights under the Plan, unless, on the Offering Date, such employee's customary employment with the Company or such Affiliate is for at least twenty (20) hours per week and at least five (5) months per calendar year. (b) The Board or the Committee may provide that, each person who, during the course of an Offering, first becomes an eligible employee of the Company or designated Affiliate will, on a date or dates specified in the Offering which coincides with the day on which such person becomes an eligible employee or occurs thereafter, receive a right under that Offering, which right shall thereafter be deemed to be a part of that Offering. Such right shall have the same characteristics as any rights originally granted under that Offering, as described herein, except that: (i) the date on which such right is granted shall be the "Offering Date" of such right for all purposes, including determination of the exercise price of such right; (ii) the period of the Offering with respect to such right shall begin on its Offering Date and end coincident with the end of such Offering; and (iii) the Board or the Committee may provide that if such person first becomes an eligible employee within a specified period of time before the end of the Offering, he or she will not receive any right under that Offering. (c) No employee shall be eligible for the grant of any rights under the Plan if, immediately after any such rights are granted, such employee owns stock possessing five percent (5%) or more of the total combined voting power or value of all classes of stock of the Company or of any Affiliate. For purposes of this subparagraph 5(c), the rules of Section 424(d) of the Code shall apply in determining the stock ownership of any employee, and stock which such employee may purchase under all outstanding rights and options shall be treated as stock owned by such employee. (d) An eligible employee may be granted rights under the Plan only if such rights, together with any other rights granted under "employee stock purchase plans" of the Company and any Affiliates, as specified by Section 423(b)(8) of the Code, do not permit such employee's rights to purchase stock of the Company or any Affiliate to accrue at a rate which exceeds twenty-five thousand dollars ($25,000) of fair market value of such stock (determined at the time such rights are granted) for each calendar year in which such rights are outstanding at any time. (e) Officers of the Company and any designated Affiliate shall be eligible to participate in Offerings under the Plan, provided, however, that the Board may provide in an Offering that certain employees who are highly compensated employees within the meaning of Section 423(b)(4)(D) of the Code shall not be eligible to participate. 6. RIGHTS; PURCHASE PRICE. (a) On each Offering Date, each eligible employee, pursuant to an Offering made under the Plan, shall be granted the right to purchase up to the number of shares of Common Stock of the Company purchasable with a percentage designated by the Board or the Committee not exceeding fifteen percent (15%) of such employee's Earnings (as defined in subparagraph 7(a)) during the period which begins on the Offering Date (or such later date as the Board or the Committee determines for a particular Offering) and ends on the date stated in the Offering, which date shall be no later than the end of the Offering. The Board or the Committee shall establish one or more dates during an Offering (the "Purchase Date(s)") on which rights granted under the Plan shall be exercised and purchases of Common Stock carried out in accordance with such Offering. (b) In connection with each Offering made under the Plan, the Board or the Committee may specify a maximum number of shares that may be purchased by any employee as well as a maximum aggregate number of shares that may be purchased by all eligible employees pursuant to such Offering. In addition, in connection with each Offering that contains more than one Purchase Date, the Board or the Committee may specify a maximum aggregate number of shares which may be purchased by all eligible employees on any given Purchase Date under the Offering. If the aggregate purchase of shares upon exercise of rights granted under the Offering would exceed any such maximum aggregate number, the Board or the Committee shall make a pro rata allocation of the shares available in as nearly a uniform manner as shall be practicable and as it shall deem to be equitable. (c) The purchase price of stock acquired pursuant to rights granted under the Plan shall be not less than the lesser of: (i) an amount equal to eighty-five percent (85%) of the fair market value of the stock on the Offering Date; or (ii) an amount equal to eighty-five percent (85%) of the fair market value of the stock on the Purchase Date. 7. PARTICIPATION; WITHDRAWAL; TERMINATION. (a) An eligible employee may become a participant in the Plan pursuant to an Offering by delivering a participation agreement to the Company within the time specified in the Offering, in such form as the Company provides. Each such agreement shall authorize payroll deductions of up to the maximum percentage specified by the Board or the Committee of such employee's Earnings during the Offering. "Earnings" is defined as an employee's regular salary or wages (including amounts thereof elected to be deferred by the employee, which would otherwise have been paid, under any arrangement established by the Company that is intended to comply with Section 125, Section 401(k), Section 402(h) or Section 403(b) of the Code or that provides non-qualified deferred compensation), which shall include overtime pay, but shall exclude bonuses, commissions, incentive pay, profit sharing, other remuneration paid directly to the employee, the cost of employee benefits paid for by the Company or an Affiliate, education or tuition reimbursements, imputed income arising under any group insurance or benefit program, traveling expenses, business and moving expense reimbursements, income received in connection with stock options, contributions made by the Company or an Affiliate under any employee benefit plan, and similar items of compensation, or such other set of inclusions or exclusions as may be determined by the Board or the Committee. The payroll deductions made for each participant shall be credited to an account for such participant under the Plan and shall be deposited with the general funds of the Company. A participant may reduce (including to zero) or increase such payroll deductions, and an eligible employee may begin such payroll deductions, after the beginning of any Offering only as provided for in the Offering. A participant may make additional payments into his or her account only if specifically provided for in the Offering and only if the participant has not had the maximum amount withheld during the Offering. (b) At any time during an Offering, a participant may terminate his or her payroll deductions under the Plan and withdraw from the Offering by delivering to the Company a notice of withdrawal in such form as the Company provides. Such withdrawal may be elected at any time prior to the end of the Offering except as provided by the Board or the Committee in the Offering. Upon such withdrawal from the Offering by a participant, the Company shall distribute to such participant all of his or her accumulated payroll deductions (reduced to the extent, if any, such deductions have been used to acquire stock for the participant) under the Offering, without interest, and such participant's interest in that Offering shall be automatically terminated. A participant's withdrawal from an Offering will have no effect upon such participant's eligibility to participate in any other Offerings under the Plan but such participant will be required to deliver a new participation agreement in order to participate in subsequent Offerings under the Plan. (c) If the fair market value of the Common Stock on any Purchase Date is lower than the fair market value of the Common Stock on the initial, or first, Offering Date for the Offering in which such Purchase Date occurs, then all participants in such Offering shall be automatically withdrawn from such Offering immediately after the exercise of their right to purchase Common Stock on such Purchase Date and automatically re-enrolled in the next Offering, which Offering shall commence on the day immediately following such Purchase Date. (d) Rights granted pursuant to any Offering under the Plan shall terminate immediately upon cessation of any participating employee's employment with the Company and any designated Affiliate, for any reason, and the Company shall distribute to such terminated employee all of his or her accumulated payroll deductions (reduced to the extent, if any, such deductions have been used to acquire stock for the terminated employee), under the Offering, without interest. (e) Rights granted under the Plan shall not be transferable by a participant otherwise than by will or the laws of descent and distribution, or by a beneficiary designation as provided in paragraph 14 and, otherwise during his or her lifetime, shall be exercisable only by the person to whom such rights are granted. 8. EXERCISE. (a) On each Purchase Date specified therefor in the relevant Offering, each participant's accumulated payroll deductions and other additional payments specifically provided for in the Offering (without any increase for interest) will be applied to the purchase of whole shares of stock of the Company, up to the maximum number of shares permitted pursuant to the terms of the Plan and the applicable Offering, at the purchase price specified in the Offering. No fractional shares shall be issued upon the exercise of rights granted under the Plan. The amount, if any, of accumulated payroll deductions remaining in each participant's account after the purchase of shares which is less than the amount required to purchase one share of stock on the final Purchase Date of an Offering shall be held in each such participant's account for the purchase of shares under the next Offering under the Plan, unless such participant withdraws from such next Offering, as provided in subparagraph 7(b), or is no longer eligible to be granted rights under the Plan, as provided in paragraph 5, in which case such amount shall be distributed to the participant after such final Purchase Date, without interest. The amount, if any, of accumulated payroll deductions remaining in any participant's account after the purchase of shares which is equal to the amount required to purchase whole shares of stock on the final Purchase Date of an Offering shall be distributed in full to the participant after such Purchase Date, without interest. (b) No rights granted under the Plan may be exercised to any extent unless the shares to be issued upon such exercise under the Plan (including rights granted thereunder) are covered by an effective registration statement pursuant to the Securities Act of 1933, as amended (the "Securities Act") and the Plan is in material compliance with all applicable state, foreign and other securities and other laws applicable to the Plan. If on a Purchase Date in any Offering hereunder the Plan is not so registered or in such compliance, no rights granted under the Plan or any Offering shall be exercised on such Purchase Date, and the Purchase Date shall be delayed until the Plan is subject to such an effective registration statement and such compliance, except that the Purchase Date shall not be delayed more than twelve months and the Purchase Date shall in no event be more than twenty-seven months from the Offering Date. If on the Purchase Date of any Offering hereunder, as delayed to the maximum extent permissible, the Plan is not registered and in such compliance, no rights granted under the Plan or any Offering shall be exercised and all payroll deductions accumulated during the Offering (reduced to the extent, if any, such deductions have been used to acquire stock) shall be distributed to the participants, without interest. 9. COVENANTS OF THE COMPANY. (a) During the terms of the rights granted under the Plan, the Company shall keep available at all times the number of shares of stock required to satisfy such rights. (b) The Company shall seek to obtain from each federal, state, foreign or other regulatory commission or agency having jurisdiction over the Plan such authority as may be required to issue and sell shares of stock upon exercise of the rights granted under the Plan. If, after reasonable efforts, the Company is unable to obtain from any such regulatory commission or agency the authority which counsel for the Company deems necessary for the lawful issuance and sale of stock under the Plan, the Company shall be relieved from any liability for failure to issue and sell stock upon exercise of such rights unless and until such authority is obtained. 10. USE OF PROCEEDS FROM STOCK. Proceeds from the sale of stock pursuant to rights granted under the Plan shall constitute general funds of the Company. 11. RIGHTS AS A STOCKHOLDER. A participant shall not be deemed to be the holder of, or to have any of the rights of a holder with respect to, any shares subject to rights granted under the Plan unless and until the participant's shareholdings acquired upon exercise of rights under the Plan are recorded in the books of the Company. 12. ADJUSTMENTS UPON CHANGES IN STOCK. (a) If any change is made in the stock subject to the Plan, or subject to any rights granted under the Plan (through merger, consolidation, reorganization, recapitalization, stock dividend, dividend in property other than cash, stock split, liquidating dividend, combination of shares, exchange of shares, change in corporate structure or other transaction not involving the receipt of consideration by the Company), the Plan and outstanding rights will be appropriately adjusted in the class(es) and maximum number of shares subject to the Plan and the class(es) and number of shares and price per share of stock subject to outstanding rights. Such adjustments shall be made by the Board or the Committee, the determination of which shall be final, binding and conclusive. (The conversion of any convertible securities of the Company shall not be treated as a "transaction not involving the receipt of consideration by the Company".) (b) In the event of: (1) a dissolution or liquidation of the Company; (2) a merger or consolidation in which the Company is not the surviving corporation; (3) a reverse merger in which the Company is the surviving corporation but the shares of the Company's Common Stock outstanding immediately preceding the merger are converted by virtue of the merger into other property, whether in the form of securities, cash or otherwise; or (4) the acquisition by any person, entity or group within the meaning of Section 13(d) or 14(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act") or any comparable successor provisions (excluding any employee benefit plan, or related trust, sponsored or maintained by the Company or any Affiliate of the Company) of the beneficial ownership (within the meaning of Rule 13d-3 promulgated under the Exchange Act, or comparable successor rule) of securities of the Company representing at least fifty percent (50%) of the combined voting power entitled to vote in the election of directors, then, as determined by the Board in its sole discretion (i) any surviving or acquiring corporation may assume outstanding rights or substitute similar rights for those under the Plan, (ii) such rights may continue in full force and effect, or (iii) participants' accumulated payroll deductions may be used to purchase Common Stock immediately prior to the transaction described above and the participants' rights under the ongoing Offering terminated. 13. AMENDMENT OF THE PLAN. (a) The Board at any time, and from time to time, may amend the Plan. However, except as provided in paragraph 12 relating to adjustments upon changes in stock, no amendment shall be effective unless approved by the stockholders of the Company within twelve (12) months before or after the adoption of the amendment, where the amendment will: (i) Increase the number of shares reserved for rights under the Plan; (ii) Modify the provisions as to eligibility for participation in the Plan (to the extent such modification requires stockholder approval in order for the Plan to obtain employee stock purchase plan treatment under Section 423 of the Code or to comply with the requirements of Rule 16b-3 promulgated under the Securities Exchange Act of 1934, as amended ("Rule 16b-3")); or (iii) Modify the Plan in any other way if such modification requires stockholder approval in order for the Plan to obtain employee stock purchase plan treatment under Section 423 of the Code or to comply with the requirements of Rule 16b-3. It is expressly contemplated that the Board may amend the Plan in any respect the Board deems necessary or advisable to provide eligible employees with the maximum benefits provided or to be provided under the provisions of the Code and the regulations promulgated thereunder relating to employee stock purchase plans and/or to bring the Plan and/or rights granted under it into compliance therewith. (b) Rights and obligations under any rights granted before amendment of the Plan shall not be impaired by any amendment of the Plan, except with the consent of the person to whom such rights were granted, or except as necessary to comply with any laws or governmental regulations, or except as necessary to ensure that the Plan and/or rights granted under the Plan comply with the requirements of Section 423 of the Code. 14. DESIGNATION OF BENEFICIARY. (a) A participant may file a written designation of a beneficiary who is to receive any shares and cash, if any, from the participant's account under the Plan in the event of such participant's death subsequent to the end of an Offering but prior to delivery to the participant of such shares and cash. In addition, a participant may file a written designation of a beneficiary who is to receive any cash from the participant's account under the Plan in the event of such participant's death during an Offering. (b) Such designation of beneficiary may be changed by the participant at any time by written notice. In the event of the death of a participant and in the absence of a beneficiary validly designated under the Plan who is living at the time of such participant's death, the Company shall deliver such shares and/or cash to the executor or administrator of the estate of the participant, or if no such executor or administrator has been appointed (to the knowledge of the Company), the Company, in its sole discretion, may deliver such shares and/or cash to the spouse or to any one or more dependents or relatives of the participant, or if no spouse, dependent or relative is known to the Company, then to such other person as the Company may designate. 15. TERMINATION OR SUSPENSION OF THE PLAN. (a) The Board in its discretion, may suspend or terminate the Plan at any time. No rights may be granted under the Plan while the Plan is suspended or after it is terminated. (b) Rights and obligations under any rights granted while the Plan is in effect shall not be impaired by suspension or termination of the Plan, except as expressly provided in the Plan or with the consent of the person to whom such rights were granted, or except as necessary to comply with any laws or governmental regulation, or except as necessary to ensure that the Plan and/or rights granted under the Plan comply with the requirements of Section 423 of the Code. 16. EFFECTIVE DATE OF PLAN. The Plan shall become effective on the same day that the Company's initial public offering of shares of common stock becomes effective (the "Effective Date"), but no rights granted under the Plan shall be exercised unless and until the Plan has been approved by the stockholders of the Company within twelve months before or after the date the Plan is adopted by the Board or the Committee, which date may be prior to the Effective Date. The Plan is amended and restated as of April 30, 2001 for any Offering commencing on or after May 1, 2001. RIBOZYME PHARMACEUTICALS, INC. By: /s/ Lawrence E. Bullock ---------------------------------- Title: Vice President of Finance & Administration Date: April 30, 2001 Exhibit 1 FAIRNESS OPINION OF FINANCIAL ADVISOR February 4, 2003 Board of Directors Ribozyme Pharmaceuticals, Inc. 2950 Wilderness Place Boulder, Colorado 80301 Members of the Board: You have requested our opinion as to the fairness, from a financial point of view, to the shareholders of the outstanding common stock (the "Common Stock") of Ribozyme Pharmaceuticals, Inc. (the "Company") of the sale to certain identified new investors (the "New Investors") of (i) up to $48.0 million of the Company's common stock at a price of $0.35 per share and (ii) five-year warrants exercisable for 20.0% of the common stock purchased by the new investors at an exercise price of $0.42 per share (the "Warrants"), with the price per share subject to adjustment downward and the number of shares under the Warrants subject to adjustment upward based upon resolution of identified balance sheet contingencies prior to or proximate to closing, (the Common Stock and Warrants together defined as the "Financing") pursuant to the Common Stock and Warrant Purchase Agreement between the Company and the new investors dated February 4, 2003 (the "Agreement"). In connection with our review of the proposed Financing and the preparation of our opinion, we have, among other things: o reviewed the financial terms and conditions as stated in the Agreement; o reviewed the audited financial statements of the Company as of and for the years ended December 31, 2001 and 2000; o reviewed the Company's Annual Reports filed on Form 10-K for the year ending December 31, 2001 and the Company's Quarterly Reports filed on 10-Q for the quarters ended March 31, 2002, June 30, 2002, and September 30, 2002; o reviewed other financial and operating information, including projections provided by the Company in writing; o reviewed certain other publicly available information on the Company; and o discussed with members of the senior management of the Company certain information relating to the aforementioned and other matters which we have deemed relevant to our inquiry. We have assumed and relied upon the accuracy and completeness of all information supplied or otherwise made available to us by the Company or any other party and have not attempted to verify independently any of such information. We have not made or obtained an independent appraisal of the assets or liabilities (contingent or otherwise) of the Company. With respect to financial projections and other information and data provided to or otherwise reviewed by or discussed with us, we have assumed that such projections and other information and data have been reasonably prepared in good faith on bases reflecting the best currently available estimates and judgments of management, and we have relied upon management to advise us promptly if any information previously provided became inaccurate or was required to be updated during the period of our review. Our opinion is based upon market, economic, financial, and other circumstances and conditions existing and disclosed to us as of February 4, 2003. Any material change in such circumstances and conditions since that date would require a re-evaluation of this opinion, which we are under no obligation to undertake. We express no opinion as to the underlying business decision to complete the Financing, the structure or tax consequences of the transactions contemplated by the Agreement, or the availability or advisability of any alternatives to the Financing. This letter does not express any opinion as to the likely trading range of the Company's common stock following the Financing, which may vary depending on numerous factors that generally impact the price of securities or on the financial condition of the Company at that time. Our opinion is limited to the fairness, from a financial point of view, of the Financing to the shareholders of the Company. We express no opinion with respect to any other reasons, legal, business, or otherwise, that may support the decision of the Board of Directors to approve or consummate the Financing. In conducting our investigation and analyses and in arriving at our opinion, we have taken into account such accepted financial and investment banking procedures and considerations as we have deemed relevant, including the review of: (i) historical and projected revenues, operating earnings, net income, and capitalization of the Company and certain other publicly-held biotechnology companies we believe to be similar to the Company; (ii) the current and projected financial position, results of operations, and capital resources of the Company; (iii) the historical market prices and trading activity of the Common Stock of the Company; (iv) financial and operating information for selected biotechnology company financing transactions that we deemed to be similar, in whole or in part, to the Financing; (v) the condition of the securities markets generally and the biotechnology financing market specifically; and (vi) the financial prospects for the Company absent the Financing. In arriving at this opinion, Raymond James did not attribute any particular weight to any analysis or factor considered by it, but rather made qualitative judgments as to the significance and relevance, if any, of each analysis and factor. Accordingly, Raymond James believes that its analyses must be considered as a whole and that selecting portions of its analyses, without considering all analyses, would create an incomplete view of the process underlying this opinion. Raymond James & Associates, Inc. ("Raymond James") is actively engaged in the health care investment banking business and regularly undertakes the valuation of investment securities in connection with public offerings, private placements, business combinations, and similar transactions. Raymond James has been engaged to render financial advisory services to the Company in connection with the proposed Financing and will receive a fee for such services, which fee is contingent upon consummation of the Financing. Raymond James also will receive a fee upon the delivery of this opinion. In addition, the Company has agreed to indemnify us against certain liabilities arising out of our engagement. In the ordinary course of our business, Raymond James may trade in the securities of the Company for our own account or for the accounts of our customers and, accordingly, may at any time hold a long or short position in such securities. It is understood that this letter is for the information of the Board of Directors of the Company in evaluating the proposed Financing and does not constitute a recommendation to any shareholder of the Company regarding how said shareholder should vote on the proposed Financing. The Company may include the full text of this letter in any proxy statement or offering memorandum prepared by the Company in connection with and describing the Financing. Except for such uses, this opinion is not to be quoted or referred to, in whole or in part, without our prior written consent, which will not be unreasonably withheld. Based upon and subject to the foregoing, it is our opinion that, as of February 4, 2003, the Financing is fair, from a financial point of view, to the holders of the Company's outstanding Common Stock.
