SHAMAN PHARMACEUTICALS, INC. NOTES TO CONDENSED FINANCIAL STATEMENTS June 30, 1996 (Unaudited) 1. Basis of Presentation Shaman Pharmaceuticals, Inc. ("Shaman" or the "Company") is a mid-stage pharmaceutical company developing new drugs from tropical plants with a history of medicinal use. These drugs are expected to provide new medicines with applications in human health care markets. The accompanying unaudited condensed financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and in accordance with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting only of normal recurring accruals) considered necessary for a fair presentation have been included. The results of operations for the interim periods shown herein are not necessarily indicative of operating results for the entire year. This unaudited financial data should be read in conjunction with the audited financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 1995, filed with the Securities and Exchange Commission on April 1, 1996. Operating expenses for 1995 have been reclassified to conform to 1996 presentation. 2. Term Loan The Company's unsecured term loan carried a principal repayment acceleration provision if the Company did not achieve certain financing or collaborative objectives by May 15, 1996. The acceleration provisions require that principal amortization be shortened from 30 months to 24 months and that monthly repayment begin May 15, 1996 instead of April 30, 1997. As of May 15, 1996, the Company had not achieved the specified milestones. Accordingly, the Company made three principal payments totaling $312,500 during the quarter and reclassified $1,250,000 of its term debt to current liabilities at June 30, 1996. 3. Subsequent Event In July 1996, the Company closed a private placement pursuant to Regulation S under the Securities Act of 1933, as amended, in which it sold 400,000 shares of Series A Convertible Preferred Stock ("Preferred Stock") at a price per share of $8.147. The Preferred Stock does not carry a dividend obligation and is convertible into common stock at the earlier of (a) the investor's option, (b) immediately following any 60 trading day period in which the Company's common stock has consistently traded higher than $8.147, or (c) July 23, 1999. If the Preferred Stock converts prior to July 23, 1999, the conversion ratio will be one share of common stock for each share of preferred. If the Preferred Stock converts on July 23, 1999, the conversion rate will be the higher of $6.00 or a weighted average of the Company's common stock price at the time of conversion. In either case, appropriate adjustments will be made for stock dividends, splits or other adjustments. In addition to the initial sale of Preferred Stock, the Company has the right, from time to time during the period beginning January 1997 and ending July 2000, to sell up to 1,200,000 shares of common stock to the investor at a formula price of 100% or 101% of a multi-day average of the Company's common stock price at the time of sale. As the Company exercises its rights under the agreement, the investor has the option to increase the shares purchased by up to an aggregate of 527,500 shares. The investor also received a six-year warrant to purchase 550,000 shares of the Company's common stock at a price of $10.184 per share. Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations Overview During the ten months from inception in May 1989 until March 1990, the Company was engaged in organizational efforts, including the formation of its Scientific Strategy Team and hiring of scientific and management personnel. In March 1990, the Company began focusing its research efforts on the discovery and development of new classes of pharmaceuticals derived from tropical plants. To date, Shaman has not sold any products and does not anticipate receiving product revenue in the near future. The Company has been unprofitable since inception and expects to continue to incur substantial and increasing losses over the next several years, due primarily to the expense of preclinical studies, clinical trials and expansion of its research and development programs. The Company expects that losses will fluctuate from quarter to quarter and that such fluctuations could be substantial. As of June 30, 1996, Shaman had an accumulated deficit of approximately $73.8 million. Shaman has financed its research and development activities and operations primarily through private placements of its equity securities, an initial public offering of common stock in January 1993, a secondary offering completed in December 1993 and, to a lesser extent, through equipment and leasehold improvement financings and collaborative agreements. Shaman centers its research efforts in therapeutic programs in which the Company believes that its drug discovery approach provides a distinct competitive advantage over other methodologies. Shaman's ethnobotanical strategy provides the basis for focusing on therapeutic targets which: (a) have symptoms that are easily observable and being treated by traditional healers using plant-based remedies; (b) are best modeled by whole animal testing; (c) have an underlying pathophysiology which is complicated and characterized by multiple abnormalities that could lead to the disease state; and (d) have large market opportunities which are not well managed by available therapies. Diabetes mellitus, which fits these parameters, is the Company's lead basic research effort. In July 1996, the Company closed a private placement pursuant to Regulation S under the Securities Act of 1933, as amended, in which it sold 400,000 shares of Series A Convertible Preferred Stock ("Preferred Stock") at a price per share of $8.147. The Preferred Stock does not carry a dividend obligation and will convert into common stock by July 23, 1999 at a price per share between $6 and $8.147, depending on the market value of the Company's common stock during the period. In addition to the sale of Preferred Stock, the Company has the right, from time to time during the period beginning January 1997 and ending July 2000, to sell up to 1,200,000 additional shares of common stock to the investor at a formula price of 100% or 101% of a multi-day average of the Company's comon stock price at the time of sale. The investor has the option to increase the shares purchased by up to an aggregate of 527,500 shares. The investor also received a six-year warrant to purchase 550,000 shares of the Company's common stock at a price of $10.184 per share. In June 1996, the Company initiated a Phase II study for Provir(TM), an oral agent for the treatment of secretory diarrhea. Previous Phase I clinical trials established Provir's safety and preclinical in vivo and in vitro research showed Provir to be potentially effective as an oral antidiarrheal agent. In October 1995, the Company announced that Virend(R), a topical agent for the treatment of herpes, was shown to be efficacious in healing herpes lesions in a Phase II clinical trial. The study involved 45 patients with AIDS and recurring genital herpes. Results from the randomized, double-blind, placebo-controlled study showed that 38% of patients receiving Virend had lesions that healed completely, compared with 14% in the placebo-controlled group. Based on these results, the Company is planning to begin a Phase III study in patients with genital herpes in the latter part of 1996. The Company has licensed several patents relating to a compound known as nikkomycin Z for the development of antifungal agents. Shaman initially intends to develop nikkomycin Z for the treatment of endemic mycoses, systemic fungal diseases which can be life threatening, especially in immunocompromised patients. The Company is finalizing its preclinical data package for nikkomycin Z and intends to begin human clinical trials late in 1996. In May 1995, Shaman entered into a three-year collaborative agreement with Ono Pharmaceutical Co., Ltd. ("Ono" or "Ono collaboration") of Osaka, Japan for the research and development of compounds for the treatment of non-insulin-dependent diabetes mellitus. Under the terms of the agreement, Shaman screens diabetes-specific plants in vivo, isolates and identifies active compounds, and participates in any medicinal chemistry modification. In turn, Ono provides preclinical and clinical development capabilities through proprietary in vitro assays and medicinal chemistry efforts. Ono will retain development and commercialization rights in Japan, South Korea, and Taiwan while Shaman will retain all other territorial rights. The Company is actively pursuing an additional partner in its diabetes research and development program. Results of Operations Six Months Ended June 30, 1996 and June 30, 1995 The Company recorded revenues of $0.5 million and $1.2 million for the quarters ended June 30, 1996 and 1995, and $1.0 million and $1.2 million for the six month periods ended June 30, 1996 and 1995, respectively. The revenues are a result of ongoing funding for research activities under the Ono collaboration, including an initial one-time access fee paid during the quarter ended June 30, 1995. Research and development expenses were $4.7 million and $4.4 million for the quarters ended June 30, 1996 and 1995, and $9.5 million and $8.3 million for the six month periods ended June 30, 1996 and 1995, respectively. The increases are attributable primarily to the Company's preclinical development activities with respect to nikkomycin Z and expanded research efforts in its diabetes program, partially offset by reduced spending for Phase II clinical trials which were completed in October 1995. Research and development expenses are likely to increase in upcoming quarters as the Company continues its clinical trial program for various product candidates. General and administrative expenses were approximately $0.9 million and $1.0 million for the quarters ended June 30, 1996 and 1995, and $1.8 million and $1.9 million for the six month periods ended June 30, 1996 and 1995, respectively. General and administrative expenses were higher for the comparable periods in 1995 due primarily to non-recurring bonus and deferred compensation expenses. General and administrative expenses for the current fiscal periods are in line with the Company's plan and are not expected to increase substantially because the Company's expanded clinical activities do not require commensurate increases in general and administrative support. Interest income decreased for the quarter ended June 30, 1996, compared with the quarter ended June 30, 1995, due to lower cash and investment balances as the Company funds its operations. The increases in interest expense for the three and six-month periods ending June 30, 1996 over the same periods in 1995 resulted from higher average debt balances in 1996. Liquidity and Capital Resources For the quarter ended June 30, 1996, the Company funded its operations through net maturities in its available-for-sale investment portfolio and through the annual research funding received from the Ono collaboration. As of June 30, 1996, the Company's cash, cash equivalents, and investments totaled approximately $18.0 million, compared with $26.7 million at December 31, 1995, with an average investment maturity of five and a half months and four and a half months, respectively. The Company invests excess cash according to its investment policy that provides guidelines with regard to liquidity, type of investment, credit rating, and concentration limits. In July 1996, the Company received gross proceeds of $3.3 million for 400,000 shares of Series A Convertible Preferred Stock in connection with the Company's private placement ("private placement"). The Preferred Stock carries no dividend requirement. In addition to the initial sale of Preferred Stock, the Company has the right, from time to time during the period beginning January 1997 and ending July 2000, to sell up to 1,200,000 additional shares of common stock to the investor at a formula price of 100% or 101% of a multi-day average of the Company's common stock price at the time of sale. As the Company exercises its rights under the agreement, the investor has the option to increase the shares purchased by up to an aggregate of 527,500 shares. The investor also received a six-year warrant to purchase 550,000 shares of the Company's Common Stock at a price of $10.184 per share. (Also see Note 3 to condensed financial statements.) In October 1995, the Company closed a $2.5 million unsecured term loan to finance capital asset acquisitions and facilities expansion. Interest on each advance is charged at the London Interbank Offered Rate (LIBOR) plus 1.5% or prime plus 0.5%. As of March 31, 1996, the Company had utilized the full $2.5 million available under the loan, with an average interest rate of approximately 7.15% at June 30, 1996. During the quarter ended June 30,1996, the Company made three principal payments totaling $312,500 in accordance with the accelerated 24 month amortization schedule required by the loan agreement. (See Note 2 to condensed financial statements.) The Company expects to incur substantial additional costs relating to the continued clinical development of its products, other research and development programs, preclinical and clinical testing, and regulatory activities. The Company anticipates that its cash, cash equivalents and investment balances of approximately $18.0 million at June 30, 1996, the collaborative revenue committed by Ono, the funding received from the July 1996 sale of preferred stock and the additional rights to sell common stock through its private placement will be adequate to fund operations under its current plan through the third quarter of 1997. Recognizing the need for additional financing, the Company continues to actively pursue collaborative partnerships with pharmaceutical companies to support its research programs. To the extent the Company is successful in creating such partnerships, cash balances would be enhanced through research funding and fees, milestone payments and possible equity investments. Additional potential sources of capital include public and private equity financings, capital equipment financings, and bank lines of credit. There can be no assurance that any of these sources of funds will be available to the Company on acceptable terms, if at all. Future Outlook In addition to historical information, this report contains predictions, estimates and other forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Actual results could differ materially from any future performance suggested in this report as a result of the risk factors set forth below and in the Company's Annual Report on Form 10-K filed with the Securities and Exchange Commission on April 1, 1996. Risk Factors History of Operating Losses; Products Still in Development; Future Profitability Uncertain. Shaman's potential products are in research and development. In order to generate revenues or profits, the Company, alone or with others, must successfully develop, test, obtain regulatory approval and market its potential products. No assurance can be given that these product development efforts will be successful, that required regulatory approvals will be obtained, or that the products, if developed and introduced, will be successfully marketed or achieve market acceptance. Additional Financing Requirements and Uncertain Access to Capital Markets. The Company has significant long-term capital requirements and, in the event Shaman receives regulatory approval for any of its products, it will incur substantial expenditures to develop manufacturing, sales and marketing capabilities. The Company will need to raise additional funds for these purposes through additional equity or debt financings, collaborative arrangements with corporate partners or from other sources. No assurance can be given that such additional funds will be available to the Company to finance its development on acceptable terms, if at all. No Assurance of FDA Approval for Marketing; Government Regulation. The Company's activities with respect to research, preclinical development, clinical trials, manufacturing and marketing in the United States and other countries are subject to extensive regulation by numerous governmental authorities including, but not limited to, the Food and Drug Administration ("FDA"). The process of obtaining FDA and other required regulatory approvals is lengthy and requires the expenditure of substantial resources. Success cannot be assured. In order to obtain FDA approval, the Company must perform clinical tests to demonstrate to the FDA's satisfaction that a product is safe and effective for its intended uses. The Company may encounter problems in clinical trials which could cause the FDA or the Company to delay or suspend clinical trials. Further, the Company must demonstrate that it is capable of manufacturing bulk product to the relevant standards. There can be no assurance that any of the Company's future studies will demonstrate their intended result, that the Company's products will not have undesirable side effects that may prevent or limit their commercial use, or that the FDA will otherwise approve any of the Company's products. Dependence on Sources of Supply. The Company currently imports all of the plant materials from which its products are derived from countries in South and Latin America, Africa and Southeast Asia. To the extent that its products cannot be economically synthesized or otherwise produced, the Company will continue to be dependent upon a supply of raw plant material. While Shaman believes it has good relationships with the local governments and suppliers of these plant materials, the Company does not have formal agreements in place with all of its suppliers. Limited Manufacturing and Marketing Experience and Capacity. The Company currently produces products only in quantities necessary for clinical trials and does not have the staff or facilities necessary to manufacture products in commercial quantities. As a result, the Company must rely on collaborative partners or third-party manufacturing facilities, which may not be available on commercially acceptable terms adequate for Shaman's long-term needs. The Company currently has no marketing or sales staff. To the extent that the Company does not or is unable to enter into co-promotion agreements or to arrange for third party distribution of its products, significant additional resources will be required to develop a marketing and sales force. Rapid Technological Change and Substantial Competition. The pharmaceutical industry is subject to rapid and substantial technological change. Technological competition from pharmaceutical companies, biotechnology companies and universities is intense. Many of these entities have significantly greater research and development capabilities, as well as substantial marketing, manufacturing, financial and managerial resources, and represent significant competition for the Company. There can be no assurance that developments by others will not render the Company's products or technologies noncompetitive or that the Company will be able to keep pace with technological developments. Uncertainty Regarding Patents and Proprietary Rights. The Company's success depends in part on its ability to obtain patent protection for its products and to preserve its trade secrets. No assurance can be given that the Company's patent applications will be approved, that any patents will provide the Company with competitive advantages for its products or that they will not be successfully challenged or circumvented by the Company's competitors. In addition, patents do not necessarily prevent others from developing competitive products. The Company has not conducted an exhaustive patent search and no assurance can be given that patents do not exist or could not be filed which would have an adverse effect on the Company's ability to market its products. Uncertainty of Health Care Reimbursement and Reform. Shaman's ability to successfully commercialize its products may depend in part on the extent to which reimbursement for the cost of such products and related treatments will be available from government health administration authorities, private health insurers and other organizations. Significant uncertainty exists as to the pricing, availability of distribution channels and reimbursement status of newly approved healthcare products. Possible Volatility of Stock Price. The market price of the Company's common stock, like the stock prices of many publicly traded biotechnology and smaller pharmaceutical companies, has been and may continue to be highly volatile. Environmental Regulation. In connection with its research and development activities and its periodic manufacturing of clinical trial materials, the Company is subject to federal, state and local laws, rules, regulations and policies governing the use, generation, manufacture, storage, air emission, effluent discharge, handling and disposal of certain materials and wastes. Although the Company believes that it has complied with these laws and regulations in all material respects and has not been required to take any action to correct any noncompliance, there can be no assurance that the Company will not be required to incur significant costs to comply with environmental and health and safety regulations in the future.

Conte and J. Stephan Dolezalek hereby certify that: (i) They are the duly elected and acting President and Chief Executive Officer and Secretary, respectively, of Shaman Pharmaceuticals, Inc., a Delaware corporation (the "Corporation"). (ii) Pursuant to the authority conferred upon the Board of Directors of the Corporation by paragraph (B) of Article IV of the Corporation's Restated Certificate of Incorporation (the "Certificate"), the Board of Directors of the Corporation on July 18, 1996 adopted the following resolutions creating a series of preferred stock designated as Series A Preferred Stock; WHEREAS, the Certificate provides for a class of shares known as Preferred Stock, issuable from time to time in one or more series; and WHEREAS, the Board of Directors of the Corporation is authorized by the Certificate to determine the powers, rights, preferences, qualifications, limitations and restrictions granted to or imposed upon any wholly unissued series of Preferred Stock, to fix the number of shares constituting any such series, and to determine the designation thereof, or any of them; WHEREAS, the Board of Directors of the Corporation desires, pursuant to its authority as aforesaid, to determine and fix the powers, rights, preferences, qualifications, limitations and restrictions relating to series of Preferred Stock and the number of shares constituting, and the designation of, each such series: NOW, THEREFORE, BE IT RESOLVED, that pursuant to the authority vested in the Board of Directors of the Corporation in accordance with the provisions of the Certificate, the series of Preferred Stock is hereby created, and the Board of Directors hereby fixes and determines the designation of, the number of shares constituting, and the rights, preferences, privileges and restrictions relating to, such series of Preferred Stock as follows: 1. Designation. The series of preferred stock of the Corporation shall be designated as "Series A Preferred Stock," $0.001 par value. 2. Authorized Number. The number of shares constituting the Series A Preferred Stock shall be Four Hundred Thousand (400,000) shares. The rights, preferences, restrictions and other matters relating to the Series A Preferred Stock set forth below are subject to the issuance of any subsequent series of preferred stock. The Board of Directors is also authorized to decrease the number of shares of any series of preferred stock prior or subsequent to the issue of that series, but not below the number of shares of such series then outstanding. In case the number of shares of any series shall be so decreased, the shares constituting such decrease shall resume the status which they had prior to the adoption of the resolution originally fixing the number of shares of such series. 3. Dividend Rights. Subject to the rights of series of Preferred Stock which may from time to time come into existence, the holders of the Series A Preferred Stock shall be entitled to receive, when and as declared by the Board of Directors, out of any assets of the corporation legally available therefor, such dividends as may be declared from time to time by the Board of Directors. The Board of Directors shall not pay any dividend to the holders of the Common Stock unless and until it has paid an equivalent dividend, on a pro rata per share basis, to the holders of the Series A Preferred Stock. 4. Liquidation Preference. (A) In the event of any liquidation, dissolution or winding up of the Corporation, whether voluntary or involuntary, the holders of the Series A Preferred Stock shall be entitled to receive, prior and in preference to any distribution of any of the assets or surplus funds of the Corporation to the holders of the Common Stock by reason of their ownership thereof, the amount of $8.147 (the AOriginal Issue Price@) per share (as adjusted for any stock dividends, combinations or splits with respect to such shares) plus all accrued or declared but unpaid dividends on such share for each share of Series A Preferred Stock then held by such holder. If upon the occurrence of such event, the assets and funds thus distributed among the holders of the Series A Preferred Stock shall be insufficient to permit the payment to such holders of the full aforesaid preferential amount, then the entire assets and funds of the Corporation legally available for distribution shall be distributed ratably among the holders of the Series A Preferred Stock in proportion to the preferential amount each such holder is otherwise entitled to receive. (B) After payment to the holders of the Series A Preferred Stock of the amounts set forth in Section 4(A) above, the entire remaining assets and funds of the Corporation legally available for distribution, if any, shall be distributed among the holders of the Common Stock in proportion to the shares of Common Stock then held by them. (C) For purposes of this Section 4, (i) any acquisition of the Corporation by means of merger or other form of corporate reorganization in which outstanding shares of the Corporation are exchanged for securities or other consideration issued, or caused to be issued, by the acquiring corporation or its subsidiary (other than a mere reincorporation transaction) or (ii) a sale of all or substantially all of the assets of the Corporation or (iii) any other transaction or series of related transactions by the Corporation in which in excess of 50% of the Corporation's voting power is transferred, shall be treated as a liquidation, dissolution or winding up of the Corporation and shall entitle the holders of Series A Preferred Stock to receive at the closing in cash, securities or other property (valued as provided in Section 4(D) below) the amount as specified in Section 4(A) above. (D) Whenever the distribution provided for in this Section 4 shall be payable in securities or property other than cash, the value of such distribution shall be as follows: (i) Securities not subject to investment letter or other similar restrictions on free marketability: (A) If traded on a securities exchange, the value shall be deemed to be the average of the closing prices of the securities on such exchange over the 30-day period ending three (3) days prior to the closing; (B) If actively traded over-the-counter, the value shall be deemed to be the average of the closing bid or sale prices (whichever are applicable) over the 30-day period ending three (3) days prior to the closing; and (C) If there is no active public market, the value shall be the fair market value thereof, as determined in good faith by the Board of Directors of the Corporation. (ii) The method of valuation of securities subject to investment letter or other restrictions on free marketability (other than restrictions arising solely by virtue of a stockholder's status as an affiliate or former affiliate) shall be to make an appropriate discount from the market value determined as above in (i) (A), (B) or (C) to reflect the approximate fair market value thereof, as determined in good faith by the Board of Directors of the Corporation. (iii) In the event of any bona-fide dispute between the Corporation and one or more holders of the Series A Preferred Stock as to any fair market value determination under clauses (i)(C) or (ii) above, such dispute shall be resolved through binding arbitration under the rules of the American Arbitration Association, with the arbitration panel consisting of persons familiar with the valuation of public and private entities and such panel being advised, as to such valuation issues, by an investment bank of nationally recognized standing, the costs thereof to be borne by the non-prevailing party. 5. Redemption. The Series A Preferred Stock is not redeemable. 6. Conversion. The holders of Series A Preferred Stock shall have conversion rights as follows (the "Conversion Rights"): (A) Right to Convert. Each share of Series A Preferred Stock shall be convertible into one share of Common Stock, as adjusted for any stock dividends, combinations or splits with respect to such shares, at any time at the option of the holder, provided, however, that the minimum number of shares which may be converted at any one time shall be 75,000 shares or such lesser number of shares as shall be then outstanding. (B) Automatic Conversion. Each share of Series A Preferred Stock shall automatically be converted into Common Stock, upon the earlier to occur of: (i) immediately in the event that at any time prior to July 23, 1999, the closing sale price (the AClosing Sale Price@) of the Corporation's Common Stock (as listed on the Nasdaq National Market) has for a period of sixty (60) consecutive trading days exceeded the Original Issue Price, which event shall be disclosed to each holder of the Series A Preferred Stock by written notification from the Corporation, in which event each share of Series A Preferred Stock shall automatically be converted into one (1) share of Common Stock, as appropriately adjusted for any stock dividends, combinations or splits with respect to such shares of Common Stock; or (ii) July 23, 1999, in which event each share of Series A Preferred Stock shall automatically be converted into the such number of shares of Common Stock as equals the Original Issue Price divided by the weighted-average Closing Sale Price for the sixty (60) consecutive trading days ending two days prior to July 23, 1999, but in no event more than the Original Issue Price divided by $6.00, in each case as appropriately adjusted for any stock dividends, combinations or splits with respect to such shares of Common Stock. (C) Mechanics of Conversion. Before any holder of Series A Preferred Stock shall be entitled to convert the same into shares of Common Stock, he shall surrender the certificate or certificates therefor, duly endorsed, at the office of this Corporation or of any transfer agent for the Series A Preferred Stock, and shall give written notice by mail, postage prepaid, or by facsimile, confirmed by mail, to this 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. This Corporation shall, as soon as practicable thereafter, issue and deliver at such office to such holder of the 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 aforesaid. Such conversion shall be deemed to have been made immediately prior to the close of business on the date of such surrender of the Series A Preferred Stock to be converted, or in the case of automatic conversion pursuant to Section 6(B), ten (10) days following written notification as provided in Section 6(B), 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. (D) Adjustments to Conversion Ratio for Stock Dividends and for Combinations or Subdivisions of Common Stock. In the event that this Corporation at any time or from time to time after the purchase date of the Series A Preferred shall declare or pay, without consideration, any dividend on the Common Stock payable in Common Stock or in any right to acquire Common Stock for no consideration, or shall effect a subdivision of the outstanding shares of Common Stock into a greater number of shares of Common Stock (by stock split, reclassification or otherwise than by payment of a dividend in Common Stock or in any right to acquire Common Stock), or in the event the outstanding shares of Common Stock shall be combined or consolidated, by reclassification or otherwise, into a lesser number of shares of Common Stock, then the number of shares of Common Stock into which the Series A Preferred Stock can be converted shall be proportionately decreased or increased, as appropriate. In the event that this Corporation shall declare or pay, without consideration, any dividend on the Common Stock payable in any right to acquire Common Stock for no consideration then the Corporation shall be deemed to have made a dividend payable in Common Stock in an amount of shares equal to the maximum number of shares issuable upon exercise of such rights to acquire Common Stock. (E) Adjustments for Reclassification and Reorganization. If the Common Stock issuable upon conversion of the Series A Preferred Stock shall be changed into the same or a different number of shares of any other class or classes of stock, whether by capital reorganization, reclassification or otherwise (other than a subdivision or combination of shares provided for in Section 6(D) above or a merger or other reorganization referred to in Section 4(C) above), the number of shares of such other class or classes of stock into which the Series A Preferred Stock shall be convertible shall, concurrently with the effectiveness of such reorganization or reclassification, be proportionately adjusted so that the Series A Preferred Stock shall be convertible into, in lieu of the number of shares of Common Stock which the holders would otherwise have been entitled to receive, a number of shares of such other class or classes of stock equivalent to the number of shares of Common Stock that would have been subject to receipt by the holders upon conversion of the Series A Preferred Stock immediately before that change. (F) No Impairment. This Corporation will not, by amendment of its Certificate or through any reorganization, recapitalization, transfer of assets, consolidation, merger, dissolution, issue 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 this Corporation, but will at all times in good faith assist in the carrying out of all the provisions of this Section 6 and in the taking of all such action as may be necessary or appropriate in order to protect the Conversion Rights of the holders of the Series A Preferred Stock against impairment. (G) No Fractional Shares and Certificate as to Adjustments. (i) No fractional shares shall be issued upon conversion 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 total number of Series A Preferred Stock the holder is at the time converting into Common Stock and the number of shares of Common Stock issuable upon such aggregate conversion. (ii) Upon the occurrence of each adjustment or readjustment of the number of shares of Common Stock into which the Series A Preferred Stock can be converted pursuant to this Section 6, this 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 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. This 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 (A) such adjustment and readjustment, (B) the conversion ratio at the time in effect, and (C) 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 the Series A Preferred Stock. (H) Notices of Record Date. In the event of any taking by this Corporation of a record of the holders of any class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend (other than a cash dividend) or other distribution, any right to subscribe for, purchase or otherwise acquire any shares of stock of any class or any other securities or property, or to receive any other right, this Corporation shall mail to each holder of Series A Preferred Stock, at least twenty (20) days prior to the date specified therein, a notice specifying the date on which any such record is to be taken for the purpose of such dividend, distribution or right, and the amount and character of such dividend, distribution or right. (I) Reservation of Stock Issuable Upon Conversion. This 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 Series A Preferred Stock such number of its shares of Common Stock as 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 shall not be sufficient to effect the conversion of all the then outstanding Series A Preferred Stock, in addition to such other remedies as shall be available to the holder of such Series A Preferred Stock, this Corporation will take such corporate action as 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. (J) Notices. Any notice required by the provisions of this Section 6 to be given to the holders of Series A Preferred Stock shall be deemed given if deposited in the United States mail, postage prepaid, and addressed to each holder of record at his address appearing on the books of this Corporation. 7. Voting Rights. (A) Each holder of shares of Series A Preferred Stock shall be entitled to the number of votes equal to the number of shares of Common Stock into which such shares of Series A Preferred Stock could then be converted and shall have voting rights and powers equal to the voting rights and powers of the Common Stock (except as otherwise expressly provided herein or as required by law, voting together with the Common Stock as a single class) and shall be entitled to notice of any stockholders' meeting in accordance with the Bylaws of the Corporation. Fractional votes shall not, however, be permitted and any fractional voting rights resulting from the above formula (after aggregating all shares into which shares of Series A Preferred Stock held by each holder could be converted) shall be rounded to the nearest whole number (with one-half being rounded upward). Each holder of Common Stock shall be entitled to one (1) vote for each share of Common Stock held. 8. Status of Converted or Redeemed Stock. In the event any Series A Preferred Stock shall be converted pursuant to Section 6 hereof, the shares so converted shall be promptly canceled after the conversion thereof. All such shares shall upon their cancellation become authorized but unissued shares of Preferred Stock and may be reissued as part of a new series of Preferred Stock to be created by resolution or resolutions of the Board of Directors, subject to the conditions and restrictions on issuance set forth herein. * * * RESOLVED FURTHER, that the Chairman of the Board, the Chief Executive Officer, the President or any Vice President, and the Secretary, the Chief Financial Officer, the Treasurer, or any Assistant Secretary or Assistant Treasurer of this Corporation are each authorized to execute, verify, and file a Certificate of Designation of Preferences in accordance with Delaware law.

Representations and Warranties of Shaman. Shaman hereby repre- sents and warrants to Fletcher on the date hereof, on the Closing Date, on the date any Preferred Share is converted (each a "Preferred Share Conversion Date"), on each Put Option Exercise Date (as defined in Annex A hereto) and on each Warrant Exercise Date (as defined in Annex B hereto) as follows: a. Shaman has been duly incorporated and is validly existing in good standing under the laws of Delaware. b. This Agreement has been duly authorized, executed and delivered by Shaman and, when duly authorized, executed and delivered by Fletcher, will be a valid and binding agreement enforceable against Shaman in accordance with its terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors' rights generally and to general principles of equity. c. Shaman has full corporate power and authority necessary to enter into this Agreement and to perform its obligations hereunder. d. No consent, approval, authorization or order of any court, governmental agency or other body is required for execution by Shaman of this Agreement or the performance by Shaman of any of its obligations hereunder. e. Neither the execution by Shaman of this Agreement nor the performance by Shaman of any of its obligations hereunder will: (1) violate, conflict with, result in a breach of, or constitute a default (or an event which with the giving of notice or the lapse of time or both would be reasonably likely to constitute a default) under (A) the Restated Certificate of Incorporation, by-laws or any other constitutive document of Shaman or any of its affiliates, (B) any decree, judgment, order, law, treaty, rule, regulation or determination of which Shaman is aware (after due inquiry) of any court, governmental agency or body, or arbitrator having jurisdiction over Shaman or any of its affiliates or any of their respective properties or assets, (C) the terms of any bond, debenture, note or any other evidence of indebtedness, or any agreement, stock option or other similar plan, indenture, lease, mortgage, deed of trust or other instrument to which Shaman or any of its affiliates is a party, by which Shaman or any of its affiliates is bound, or to which any of the properties or assets of Shaman or any of its affiliates is subject, or (D) the terms of any "lock-up" or similar provision of any underwriting or similar agreement to which Shaman or any of its affiliates is a party; or (2) result in the creation or imposition of any lien, charge or encumbrance upon (A) any Preferred Share, the Warrant or any Common Stock or (B) any of the properties or assets of Shaman or any of its affiliates. f. When issued to Fletcher against payment therefor in accordance with the terms of this Agreement, any Preferred Share, any Put Option or the Warrant, each share of Common Stock: (1) will have been duly and validly authorized, duly and validly issued, fully paid and non-assessable; (2) will be free and clear of any security interests, liens, claims or other encumbrances; and (3) will not have been issued or sold in violation of any preemptive or other similar rights of the holders of any securities of Shaman. g. When any share of Common Stock is issued to Fletcher pursuant to the terms of this Agreement, any Preferred Share, any Put Option or the Warrant, the Common Stock will be quoted on NASDAQ or listed and registered on a national securities exchange (as defined in the United States Securities Exchange Act of 1934, as amended (the "Exchange Act")). h. Shaman is a Reporting Issuer within the meaning of Regulation S. i. There is no pending or, to the best knowledge of Shaman, threatened action, suit, proceeding or investigation before any court, governmental agency or body, or arbitrator having jurisdiction over Shaman or any of its affiliates that would materially affect the execution by Shaman of, or the performance by Shaman of its obligations under, this Agreement, provided, however, that the representations and warranties contained in this Section 3(i) shall not apply to any action, threatened action, suit, proceeding or investigation initiated by Fletcher and shall not be required to be given in respect of any Preferred Share Conversion Date or Warrant Exercise Date. j. None of Shaman's filings with the United States Securities and Exchange Commission (the "S.E.C.") under the Securities Act or under Section 13(a) or 15(d) of the Exchange Act (each, an "SEC Filing"), or press releases material to the business of Shaman as a whole, contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements, in the light of the circumstances under which they were made, not misleading. k. Since the date of Shaman's most recent SEC Filing, there has not been, and Shaman is not aware of any development that might result in, any material adverse change in the condition, financial or otherwise, or in the business affairs or business prospects of Shaman, whether or not arising in the ordinary course of business, except as disclosed in such SEC Filing, provided, however, that the representations and warranties contained in this Section 3(k) shall not be required to be given in respect of any Preferred Share Conversion Date or Warrant Exercise Date. l. The offer and sale of the Preferred Shares, the Common Stock, the Warrant and the Warrant Shares to Fletcher pursuant to this Agreement will, subject to compliance by Fletcher with the applicable representations and warranties contained in Section 4 hereof and with the applicable covenants and agreements contained in Section 6 hereof, be made in accordance with the provisions and requirements of Regulation S and any applicable state law. m. Neither Shaman nor any of its affiliates nor any person acting on its or their behalf has engaged or will engage in any Directed Selling Efforts with respect to the Preferred Shares, the Common Stock, the Warrant or the Warrant Shares, and all such persons understand and have complied and will otherwise comply with the requirements of Regulation S. n. The transactions contemplated by this Agreement are not part of a plan or scheme on the part of Shaman, any of its affiliates or any person acting on its or their behalf to evade the registration provisions of the Securities Act. o. Shaman has not issued, and after the Closing Date will not issue, any stop transfer order or other order impeding the sale and delivery of the Preferred Shares, the Common Stock, the Warrant or the Warrant Shares issuable hereunder except for a stop order restricting the sale of any of the foregoing securities to any person in the United States or to or for the account or benefit of any U.S. Person during an applicable Restricted Period. Notwithstanding the foregoing provision, Shaman shall place the following legend on the certificate representing any security issued hereunder prior to the expiration of the Restricted Period (as defined herein) applicable to such security: The securities represented by this certificate were issued on July 26, 1996 (the "Original Issue Date") pursuant to the Subscription Agreement dated July 25, 1996 between Shaman Pharmaceuticals, Inc. ("Shaman") and Fletcher International Limited. The securities represented by this certificate have not been registered under the Securities Act of 1933, as amended (the "Securities Act"), and have been sold in reliance on the exemption from registration provided by Regulation S under the Securities Act ("Regulation S"). Prior to the expiration of a 40-day restricted period beginning on the Original Issue Date (the "Restricted Period"), the securities represented by this certificate may not be offered or sold, directly or indirectly, within the United States (as defined in Regulation S under the Act), to a U.S. Person (as defined in Regulation S under the Act) or for the account or benefit of a U.S. Person. Neither Shaman Pharmaceuticals, Inc. nor its transfer agent shall be obligated to remove this legend unless it shall have received an opinion of counsel stating that such removal complies with the requirements of Regulation S (under the Act). provided, however, that as used in this Agreement and as reflected in such legend, the term "Restricted Period," with respect to any security, shall mean the Restricted Period then applicable to such security pursuant to Regulation S (or any applicable successor thereto). p. Neither Shaman nor any of its affiliates has offered to sell or sold any Common Stock or any securities convertible or exchangeable into or exercisable for Common Stock in reliance upon Regulation S at any time during the past 12 months; and there are no outstanding convertible or exchangeable securities that have been offered or sold in reliance upon Regulation S, except, in each case the Warrant and the Preferred Shares sold pursuant hereto. q. (i) If, any time after the date hereof, the S.E.C. has reinterpreted Regulation S or has promulgated, or the United States Congress has legislated, a successor or revision to Regulation S, and such reinterpretation, successor provision or revision imposes a Restricted Period applicable to any security issued or issuable hereunder that is greater than that in effect on the date of this Agreement, or would materially impair the ability of Fletcher or any of its affiliates (as defined in Rule 144(a) under the Securities Act) to offer, sell or otherwise dispose of any such security pursuant to Regulation S as contemplated hereby, or requires any such offer, sale or other disposition to be registered under the Securities Act, then upon the written request of Fletcher (a "Registration Request"), Shaman shall, as promptly as practicable thereafter and at its own expense, file a registration statement (the "Registration Statement") under the Securities Act covering the sale or resale of all such securities (each a "Covered Security"); provided, however, that in no event shall Shaman be required to file a Registration Statement or otherwise comply with a Registration Request to the extent that such reinterpretation, successor provision or revision imposes limitations on the offer, sale or other disposition of any Covered Security by Fletcher pursuant to Regulation S solely as a result of Fletcher's hedging or selling short such Covered Security or engaging in any other activity the effect of which is to decrease or limit Fletcher's investment risk with respect to such Covered Security in violation of such reinterpretation, successor provision or revision. Prior to the effectiveness of such Registration Statement, Shaman shall not be entitled to exercise any Put Option under this Agreement. Upon the effectiveness of such Registration Statement (A) Shaman shall issue such securities to Fletcher in accordance with the terms hereof, (B) the provisions of Sections 3(l), (m) and (o), 4(e), (f), (g), (h), (i) and (j), 5(a), (b), (c) and (d), 6(a) (collectively, the "Specified Provisions"), 7(a) and (b) (to the extent applicable to the Specified Provisions), 8(b), (c) and (d) (to the extent applicable to the Specified Provisions) shall thereafter be of no force and effect with respect to the issuance of such Covered Securities and (C) the provision that not more than one Put Option shall be exercisable within any six-month period shall be of no further force and effect, and with respect to any Put Options outstanding at that time, not more than one such Put Option shall be exercisable within any 50 Trading Day period and no such Put Option shall be exercisable to the extent that (i) the number of shares of Common Stock issuable to Fletcher pursuant to such Put Option plus (ii) the number of shares of Common Stock issued to Fletcher during the immediately preceding 365 days pursuant to any Put Option plus (iii) the total number of shares of Common Stock issuable to Fletcher pursuant to the Preferred Shares (whether or not such Preferred Shares have been converted) plus (iv) the total number of Warrant Shares issuable to Fletcher pursuant to the Agreement (whether or not such Warrant Shares have then been issued), would equal or exceed 10% of the number of shares of Common Stock outstanding on the relevant Put Option Exercise Date (including common stock issuable under (iii) or (iv) above), provided, however, that, if such Registration Statement has not been declared effective before the 180th day following the date of such Registration Request, then (X) any Put Options outstanding under this Agreement shall immediately expire and shall not thereafter be exercisable, and Fletcher shall have no further liability whatsoever with respect thereto and (Y) Shaman shall use its best efforts to cause such Registration Statement to become effective as promptly as practicable in respect of any outstanding portion of the securities the sale or resale of which is required to be so registered. (ii) In the case of the registration effected by Shaman pursuant to this Section 3(q) registration provisions, Shaman will use its best efforts to: (i) keep such registration effective until the earlier of (A) the third anniversary of the issuance of each Covered Security, (B) such date as all of the Covered Securities have been sold by Fletcher or (C) such time as all of the Covered Securities held by Fletcher can be sold by Fletcher or any of its affiliates (within the meaning of Rule 144(a) under the Securities Act) within a given three-month period without compliance with the registration requirements of the Securities Act pursuant to Rule 144 under the Securities Act ("Rule 144"); (ii) prepare and file with the S.E.C. such amendments and supplements to the Registration Statement and the prospectus used in connection with the Registration Statement (as so amended and supplemented from time to time, the "Prospectus") as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all Covered Securities by Fletcher or any of its affiliates (within the meaning of Rule 144(a) under the Securities Act); (iii) furnish such number of Prospectuses and other documents incident thereto, including any amendment of or supplement to the Prospectus, as Fletcher from time to time may reasonably request; (iv) cause all Covered Securities that are Common Stock to be listed on each securities exchange and quoted on each quotation service on which similar securities issued by Shaman are then listed or quoted; (v) provide a transfer agent and registrar for all Covered Securities and a CUSIP number for all Covered Securities; (vi) otherwise use its best efforts to comply with all applicable rules and regulations of the S.E.C.; and (vii) file the documents required of Shaman and otherwise use its best efforts to obtain and maintain requisite blue sky clearance in (A) all jurisdictions in which any of the Covered Securities are originally sold and (B) all other states specified in writing by Fletcher, provided as to clause (B), however, that Shaman shall not be required to qualify to do business or consent to service of process in any state in which it is not now so qualified or has not so consented. (iii) Shaman shall furnish to Fletcher upon request a reasonable number of copies of a supplement to or an amendment of such Prospectus as may be necessary in order to facilitate the public sale or other disposition of all or any of the Covered Securities by Fletcher or any of its affiliates (within the meaning of Rule 144(a) under the Securities Act); pursuant to the Registration Statement. (iv) With a view to making available to Fletcher and its affiliates (within the meaning of Rule 144(a) under the Securities Act) the benefits of Rule 144 and Form S-3 under the Securities Act, Shaman covenants and agrees to: (i) make and keep available adequate current public information (within the meaning of Rule 144(c)) concerning Shaman, until the earlier of (A) the third anniversary of the issuance of each Covered Security of (B) such date as all of the Covered Securities shall have been resold by Fletcher or any of its affiliates (within the meaning of Rule 144(a) under the Securities Act); (ii) maintain its status as a Reporting Issuer and file with the S.E.C. in a timely manner all reports and other documents required of Shaman for use of Form S-3; and (iii) furnish to Fletcher upon request, as long as Fletcher owns any Covered Securities (A) a written statement by Shaman that it has complied with the reporting requirements of the Securities Act and the Exchange Act, (B) a copy of the most recent annual or quarterly report of Shaman, and (C) such other information as may be reasonably requested in order to avail Fletcher and its affiliates (within the meaning of Rule 144(a) under the Securities Act) of Rule 144 or Form S-3 with respect to such Covered Securities. (v) Notwithstanding anything else in this Section 3(q), if, at any time during which a Prospectus is required to be delivered in connection with the sale of any Covered Securities, Shaman determines in good faith that a development has occurred or a condition exists as a result of which the Registration Statement or the Prospectus contains a material misstatement or omission, Shaman will immediately notify Fletcher thereof by telephone and in writing. Upon receipt of such notification, Fletcher and its affiliates (within the meaning of Rule 144(a) under the Securities Act) will immediately suspend all offers and sales of any Covered Securities pursuant to the Registration Statement. In such event, Shaman will amend or supplement the Registration Statement as promptly as practicable and will take such other steps as may be required to permit sales of the Covered Securities thereunder by Fletcher and its affiliates (within the meaning of Rule 144(a) under the Securities Act) in accordance with applicable federal and state securities laws. Shaman will promptly notify Fletcher after it has determined in good faith that such sales have become permissible in such manner and will promptly deliver copies of the Registration Statement and the Prospectus (as so amended or supplemented) to Fletcher in accordance with paragraph (ii) of this Section 3(q). Notwithstanding the foregoing, (A) under no circumstances shall Shaman be entitled to exercise its right to suspend sales of any Covered Securities pursuant to the Registration Statement more than two times in any twelve-month period, (B) the period during which such sales may be suspended (each a "Blackout Period") shall not exceed thirty days and (C) no Blackout Period may commence less than 30 days after the end of the preceding Blackout Period. Upon the commencement of a Blackout Period pursuant to this Section 3(q), Fletcher will immediately notify Shaman of any contracts to sell any Covered Securities (each a "Sales Contract") that Fletcher or any of its affiliates (within the meaning of Rule 144(a) under the Securities Act) has entered into prior to the commencement of such Blackout Period and that would require delivery of such Covered Securities during such Blackout Period, which notice will contain the aggregate sale price and volume of Covered Securities pursuant to such Sales Contract. Upon receipt of such notice, Shaman will immediately notify Fletcher of its election either (i) to terminate the Blackout Period and, as promptly as practicable, amend or supplement the Registration Statement or the Prospectus in order to correct the material misstatement or omission and deliver to Fletcher copies of such amended or supplemented Registration Statement and Prospectus in accordance with paragraph (ii) of this Section 3(q) or (ii) to continue the Blackout Period in accordance with this paragraph. If Shaman elects to continue the Blackout Period, and Fletcher or any of its affiliates (within the meaning of Rule 144(a) under the Securities Act) is therefore unable to consummate the sale of Covered Securities pursuant to the Sales Contract (such unsold Covered Securities being hereinafter referred to herein as the "Unsold Securities"), Shaman will promptly indemnify each Fletcher Indemnified Party (as such term is defined in Section 11(a) below) against any Proceeding (as such term is defined in Section 11(a) below) that each Fletcher Indemnified Party may incur arising out of or in connection with Fletcher's breach or alleged breach of any such Sales Contract, and Shaman shall reimburse each Fletcher Indemnified Party for any reasonable costs or expenses (including reasonable legal fees) incurred by such party in investigating or defending any such Proceeding (collectively, the "Indemnification Amount"); provided, however, that each Fletcher Indemnified Party shall take all actions reasonably necessary or appropriate to mitigate such Indemnification Amount; and provided further, however, that the Indemnification Amount shall be reduced by an amount equal to the number of Unsold Securities multiplied by the difference between (x) the actual per share price received by Fletcher or any of its affiliates (within the meaning of Rule 144(a) under the Securities Act) upon the sale of the Unsold Securities (if such sale occurs within three Trading Days of the end of the Blackout Period) or the closing sale price of the Common Stock on NASDAQ or other national securities exchange on which the Common Stock is then listed on the third Trading Day after the end of the Blackout Period (if the Unsold Securities are not sold by Fletcher or any of its affiliates (within the meaning of Rule 144(a) under the Securities Act) within three Trading Days of the end of the Blackout Period), and (y) the per share sale price for the Unsold Securities provided in the Sales Contract. 4. Representations and Warranties of Fletcher. Fletcher hereby represents and warrants to Shaman as follows: a. Fletcher has been duly incorporated and is validly existing in good standing under the laws of the Cayman Islands. b. This Agreement has been duly authorized, executed and delivered by Fletcher and, when duly authorized, executed and delivered by Shaman, will be a valid and binding agreement enforceable against Fletcher in accordance with its terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors' rights generally and to general principles of equity. c. Fletcher understands that no United States federal or state agency has passed on, reviewed or made any recommendation or endorsement of the Preferred Shares, the Common Stock, the Warrant or the Warrant Shares; d. In making the decision to purchase the Preferred Shares, the Common Stock, the Warrant and the Warrant Shares in accordance with this Agreement, Fletcher has relied solely upon independent investigations made by it and not upon any representations made by Shaman other than those made pursuant to this Agreement. e. Fletcher understands that the Preferred Shares, the Common Stock, the Warrant and the Warrant Shares have not been and will not be registered under the Securities Act and may not be reoffered or resold other than pursuant to such registration or an available exemption therefrom. f. Fletcher is not a U.S. Person and is not acquiring the Preferred Shares, the Common Stock, the Warrant or any Warrant Shares for the account or benefit of any U.S. Person, and Fletcher is not an affiliate (within the meaning of Rule 144 under the Securities Act) of Shaman. g. At the time the buy orders for the Preferred Shares and the Warrant (and any Common Stock and Warrant Shares issued during the applicable Restricted Period) were originated, Fletcher was located outside the United States. h. Neither Fletcher nor any of its affiliates nor anyone acting on its or their behalf has engaged or will engage in any Directed Selling Efforts with respect to the Preferred Shares, the Common Stock, the Warrant or any Warrant Shares, and all such persons understand and have complied and will otherwise comply with the requirements of Regulation S. i. Fletcher: (1) will not, during the Restricted Period applicable to the Preferred Shares, the Common Stock, the Warrant and the Warrant Shares, offer or sell any of the foregoing securities (or create or maintain any derivative position equivalent thereto) in the United States, to or for the account or benefit of a U.S. Person or other than in accordance with Regulation S; and (2) will, after the expiration of the applicable Restricted Period, offer, sell, pledge or otherwise transfer the Preferred Shares, the Common Stock, the Warrant or any Warrant Shares (or create or maintain any derivative position equivalent thereto) only pursuant to registration under the Securities Act or an available exemption therefrom and, in any case, in accordance with applicable state securities laws. j. Fletcher is purchasing the Preferred Shares, the Warrant and the Warrant Shares for its own account, for the purpose of investment and not with a view to a distribution thereof. k. The transactions contemplated by this Agreement are not part of a plan or scheme on the part of Fletcher, any of its affiliates or any person acting on its or their behalf to evade the registration requirements of the Securities Act. 5. Covenants of Shaman. Shaman covenants and agrees with Fletcher as follows: a. For so long as any Preferred Share is outstanding or any of the Put Options have not been exercised or any portion of the Warrant remains outstanding, and in either case for a period of 40 days thereafter, Shaman will continue to be a Reporting Issuer within the meaning of Regulation S and will maintain the eligibility of the Common Stock for quotation on NASDAQ or listing on a national securities exchange (as defined in the Exchange Act). b. For so long as any Preferred Share is outstanding or any of the Put Options have not been exercised or any portion of the Warrant remains outstanding, and in either case for a period of six months thereafter, Shaman will not offer or sell any Common Stock or any securities convertible into or exchangeable into Common Stock in reliance upon Regulation S. c. For so long as any Preferred Share is outstanding or any of the Put Options have not been exercised or any portion of the Warrant remains outstanding, and in either case for a period of 40 days thereafter, neither Shaman nor any of its affiliates nor any person acting on its or their behalf will engage in any Directed Selling Efforts with respect to the Preferred Shares, the Common Stock, the Warrant or Warrant Shares. d. For so long as any Preferred Share is outstanding or any of the Put Options have not been exercised or any portion of the Warrant remains outstanding, and in either case for a period of 40 days thereafter, Shaman will ensure that all applicable Offering Restrictions with respect to the Preferred Shares, the Common Stock, the Warrant and the Warrant Shares are thoroughly complied with and satisfied. e. Beginning on the date hereof and for so long as any Preferred Share is outstanding or any of the Put Options have not been exercised or any portion of the Warrant remains outstanding, and in either case for a period of 40 days thereafter, Shaman will promptly notify Fletcher if (i) any event shall have occurred as a result of which any SEC Filing would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or (ii) there is any public disclosure of material information regarding Shaman or its financial condition prospects or results of operation. f. At any time after the expiration of any Restricted Period with respect to the Preferred Shares, the Common Stock, the Warrant or any Warrant Shares, upon the request of Fletcher accompanied by an opinion of Rogers & Wells (or such other counsel as shall be reasonably satisfactory to Shaman and its transfer agent (if any)) to the effect that the removal of the legend referred to in Section 4(o) would then be permitted under Regulation S and that the resale of any such securities would not require registration under the Securities Act, Shaman shall, or shall cause its transfer agent (if any) to, accept from Fletcher the legended certificates representing such securities and deliver in their place unlegended certificates therefor. g. Shaman will comply with the terms and conditions of the Put Option and the Warrant as set forth in Annex A and Annex B hereto, respectively (as duly amended from time to time by the parties hereto), and when issued, each Preferred Share will be substantially in the form of Annex C hereto. h. For so long as any Preferred Share is outstanding or any of the Put Options have not been exercised or any portion of the Warrant remains outstanding, Shaman shall at all times reserve and keep available, free from pre-emptive rights, out of its authorized but unissued Common Stock, for issuance upon conversion of such Preferred Shares and exercise of such Put Options and Warrant, the maximum number of shares of Common Stock then so issuable. 6. Covenants of Fletcher. Fletcher hereby covenants and agrees with Shaman as follows: a. During any Restricted Period applicable to the Preferred Shares, the Common Stock, the Warrant or the Warrant Shares, neither Fletcher nor any of its affiliates nor any person acting on its or their behalf will: (1) offer or sell such Preferred Shares, Common Stock, Warrant or the Warrant Shares other than in an Offshore Transaction; (2) engage in any Directed Selling Efforts with respect to such Preferred Shares, Common Stock, Warrant or Warrant Shares; (3) offer or sell such Preferred Shares, Common Stock, Warrant or Warrant Shares other than: (A) in accordance with Rule 903 or Rule 904 of Regulation S; (B) pursuant to registration under the Securities Act or (C) pursuant to an available exemption therefrom; and (4) offer or sell such Preferred Shares, Common Stock, Warrant or Warrant Shares to any U.S. Person or for the account or benefit of any U.S. Person. 7.

SHAMAN PHARMACEUTICALS, INC. By: /s/ Lisa A. Conte Name: Lisa A. Conte Title: President and CEO FLETCHER INTERNATIONAL LIMITED By: /s/ Alphonse Fletcher, Jr. Name: Alphonse Fletcher, Jr. Title: CEO ANNEX A TERMS OF PUT OPTIONS GRANTED BY FLETCHER INTERNATIONAL LIMITED TO SHAMAN PHARMACEUTICALS, INC. The Put Options granted by Fletcher International Limited ("Fletcher") to Shaman Pharmaceuticals, Inc. ("Shaman") pursuant to the Subscription Agreement dated July 25, 1996 between Fletcher and Shaman (the "Subscription Agreement"), including any additional Put Options granted pursuant to Paragraph 4 hereof, shall have the terms and conditions set forth below. This Annex A forms a part of the Subscription Agreement, and the following terms and conditions are subject to the representations, warranties and agreements and further provisions contained in the Subscription Agreement. Unless otherwise defined herein, capitalized terms used herein shall have the meanings set forth in the Subscription Agreement. 1. Option to Sell Each of the Put Options granted pursuant to the Subscription Agreement shall entitle Shaman to sell to Fletcher and obligate Fletcher to purchase from Shaman, upon the terms and conditions set forth in the Subscription Agreement and herein, 200,000 newly issued shares of Common Stock, subject to adjustment as provided in Paragraph 4 hereof (the "Put Option Amount"), at the price per share (the "Put Option Price") computed as set forth below. 2. Exercisable by Shaman The Put Options shall be exercisable only by Shaman and only upon the terms and conditions and subject to the limitations set forth in the Subscription Agreement and herein, and the Put Options may not be transferred, sold, pledged, assigned or otherwise disposed of to any person. 3. Certain Restrictions on Exercise (a) The Put Options shall be exercisable on any Trading Day (each, a "Put Option Exercise Date") from but excluding January 27,1997 to and including July 28, 2000 (the "Put Option Termination Date"); provided, however that, subject to the provisions of Section 3(q) of the Subscription Agreement, not more than one Put Option shall be exercisable within any six-month period; and provided further, however, that no Put Option shall be exercisable unless Shaman shall have delivered to Fletcher on the relevant Put Option Exercise Date a certificate of the Chief Executive Officer and Chief Financial Officer of Shaman, dated such Put Option Exercise Date, confirming that each of the representations and warranties made by Shaman in the Subscription Agreement are true and correct as of such Put Option Exercise Date. Notwithstanding anything to the contrary contained herein or in the Subscription Agreement, in no event shall any Put Option be exercisable to the extent that (i) the number of shares of Common Stock issuable to Fletcher pursuant to such Put Option plus (ii) the number of shares of Common Stock previously issued to Fletcher pursuant to any Put Option plus (iii) the total number of shares of Common Stock issuable to Fletcher pursuant to the Preferred Shares (whether or not such Preferred Shares have then been converted) plus (iv) the total number of Warrant Shares issuable to Fletcher pursuant to the Agreement (whether or not such Warrant Shares have then been issued), would equal or exceed 2,677,500 shares. (b) On any Put Option Settlement Date (as defined below), the Put Option Price payable by Fletcher shall be (i) 101 percent of the Weighted Average Price (as hereinafter defined) during the period (the "Original Pricing Period") from but excluding the second Trading Day after the relevant Put Option Exercise Date and to and including the * * * Day thereafter, or (ii) if written notice is given by Fletcher at any time after the fifth day of any Pricing Period but prior to the end of such Pricing Period, the Weighted Average Price (as hereinafter defined) during the period (the "Adjusted Pricing Period") from but excluding the * * * Day prior to such Put Option Exercise Date to and including such Put Option Exercise Date. "Weighted Average Price" shall mean, with respect to any specified time period, the arithmetic average of the daily volume-weighted average sale prices (rounded to the nearest tenth of a cent) of the Shaman Common Stock on NASDAQ, as reported by Bloomberg L.P., or, if Bloomberg, L.P. is not then reporting such information, any successor service mutually agreed upon by Shaman and Fletcher. [* INDICATES THAT MATERIAL HAS BEEN OMITTED AND CONFIDENTIAL TREATMENT HAS BEEN REQUESTED THEREFOR. ALL SUCH OMITTED MATERIAL HAS BEEN FILED SEPARATELY WITH THE COMMISSION PURSUANT TO RULE 24b-2.] 4. Additional Put Options Fletcher shall have the right (on the Business Day immediately prior to each Put Right Closing Date, as defined below) to increase the applicable Put Option Amount to a maximum of 400,000 shares of Common Stock or to reduce the applicable Put Option Amount to a minimum of four times the average of the daily volume of shares of Common Stock traded on the Nasdaq Stock Market during the applicable Original Pricing Period or Adjusted Pricing Period, as the case may be. The excess, if any, of the original Put Option Amount over such decreased Put Option Amount shall be referred to herein as the "Remaining Shares". If Fletcher does reduce the Put Option Amount in one or more instances, Shaman will receive that number of additional Put Options on a cumulative basis equal to the total number of Remaining Shares divided by 200,000, plus an additional Put Option for any fractional remainder of the Remaining Shares (exercisable only to the extent of the number of Remaining Shares in such fractional remainder). 5. Certain Exercise Procedures On any Put Option Exercise Date, Shaman may exercise a Put Option by delivering notice thereof to Fletcher in accordance with the Subscription Agreement. On the second Business Day following (i) the end of the Original Pricing Period or (ii) the date on which Fletcher exercises its right to calculate the put option price using the Adjusted Pricing Period, as the case may be, or such later date as shall be agreed by Shaman and Fletcher (a "Put Option Settlement Date"), Shaman shall issue to Fletcher the number of shares of Common Stock equal to the Put Option Amount calculated as provided herein against payment by Fletcher of the Put Option Price in New York Clearing House (next day) funds in accordance with the Subscription Agreement. 6. Expiration and Termination (a) Any Put Option (including any additional Put Options granted pursuant to Paragraph 4 hereof) that has not been exercised by Shaman in accordance with the terms of the Subscription Agreement and hereof by 5:00 p.m. (New York time) on the Put Option Termination Date shall immediately expire and not thereafter be exercisable, and Fletcher shall have no further obligation whatsoever with respect to any such Put Option. The Warrant represented by this certificate was issued on July 26, 1996 (the "Original Issue Date") pursuant to the Subscription Agreement dated July 25, 1996 between Shaman Pharmaceuticals, Inc. and Fletcher International Limited. Neither the Warrant represented by this certificate nor the securities issuable upon exercise hereof have been registered under the Securities Act of 1933, as amended (the "Act"). The Warrant represented hereby has been sold in reliance on the exemption from registration provided by Regulation S under the Act ("Regulation S"). Prior to the expiration of a 40-day restricted period beginning on the Original Issue Date (the "Restricted Period"), the Warrant represented by this certificate may not be exercised, offered or sold, directly or indirectly, within the United States (as defined in Regulation S under the Act), to a U.S. Person (as defined in Regulation S under the Act) or for the account or benefit of a U.S. Person. Neither Shaman Pharmaceuticals, Inc. nor its transfer agent shall be obligated to remove this legend unless it shall have received an opinion of counsel stating that such removal complies with the requirements of Regulation S. Warrant No. _________________ 550,000 Warrant Shares WARRANT CERTIFICATE SHAMAN PHARMACEUTICALS, INC. This Warrant Certificate certifies that FLETCHER INTERNATIONAL LIMITED, or registered assigns, is the registered holder of one Warrant (the "Warrant") expiring on the Termination Date (as defined below) to purchase up to 550,000 shares (the "Warrant Shares") of common stock, par value $.001 per share (the "Common Stock"), of Shaman Pharmaceuticals, Inc., a Delaware corporation (the "Issuer"), at the Exercise Price (as defined below). The Warrant represented hereby was issued on July 26, 1996 (the "Original Issue Date") pursuant to the Subscription Agreement dated July 25, 1996 (the "Subscription Agreement"), between the Issuer and Fletcher International Limited ("Fletcher"), and is subject to the terms and conditions thereof. Unless otherwise defined herein, capitalized terms used herein shall have the meanings set forth in the Subscription Agreement. A copy of the Subscription Agreement may be obtained by the registered holder hereof upon written request to the Issuer. The Warrant represented hereby may be exercised on any Business Day (a "Warrant Exercise Date") from but excluding the Original Issue Date to and including July 25, 2002 (the "Termination Date"). The Warrant entitles the registered holder hereof to receive from the Issuer upon exercise up to the number of Warrant Shares set forth on the face hereof upon surrender of this Warrant Certificate as provided on the reverse hereof and payment of the Exercise Price defined below (the "Exercise Price") (plus transfer taxes, if applicable) to the Issuer in cash or by certified or official bank check. The Exercise Price per Warrant Share shall be $10.184. The Warrant represented hereby shall have the following additional terms: 1. The Warrant represented hereby may be exercised upon surrender of this Warrant Certificate by the registered holder hereof to the Issuer at its principal office on any Exercise Date with the Exercise Notice attached hereto (an "Exercise Notice") duly completed and signed by the registered holder hereof and upon payment by such holder to the Issuer of the Exercise Price (plus transfer taxes, if applicable) for the total number of Warrant Shares in respect of which such Warrant is then exercised. The Warrant represented hereby shall be exercisable only in the minimum amount of 30,000 Warrant Shares and integral multiples of 30,000 Warrant Shares in excess thereof (or such lesser amount as shall constitute the full amount of this Warrant). 2. On the Business Day following an Exercise Date (an "Issue Date") the Issuer shall issue and cause to be delivered to the registered holder hereof at such address as such holder shall specify in the Exercise Notice a certificate or certificates for the number of full Warrant Shares issuable upon the exercise of such Warrant, registered in such holder's name, together with cash (if any) as provided in paragraph 4. Such certificate or certificates shall be deemed to have been issued and any person so designated to be named therein shall be deemed to have become a holder of record of such Warrant Shares as of such Exercise Date. 3. If on such Issue Date the number of Warrant Shares to be delivered shall be less than the total number of Warrant Shares deliverable hereunder, there shall be issued to the holder hereof or his assignee on such Issue Date a new warrant certificate substantially identical to this Warrant Certificate, except that such new warrant certificate shall evidence the right to purchase the number of Warrant Shares equal to (x) the total number of Warrant Shares deliverable hereunder less (y) the number of Warrant Shares so delivered. 4. The Issuer shall not be required to issue fractional Warrant Shares on the exercise of the Warrant represented hereby. The number of full Warrant Shares which shall be issuable upon the exercise of the Warrant shall be computed on the basis of the aggregate number of Warrant Shares purchasable on exercise of the Warrant so presented. If any fraction of a Warrant Share would, except for the provisions of this paragraph 4, be issuable on the exercise of the Warrant, the Issuer shall pay an amount in cash equal to the closing sale price of the Common Stock per Warrant Share on the day immediately preceding the date the Warrant is presented for exercise, multiplied by such fraction. 5. For so long as the Warrant represented hereby has not been exercised in full, the Issuer shall at all times reserve and keep available, free from preemptive rights, out of its authorized but unissued Common Stock, for issuance upon exercise of the Warrant represented hereby, the maximum number of Common Stock then so issuable (as adjusted from time to time pursuant to paragraph 10). 6. By accepting delivery of this Warrant Certificate, the registered holder hereby covenants and agrees with the Issuer not to exercise or transfer the Warrant represented hereby except in compliance with the terms of the Subscription Agreement and this Warrant Certificate. 7. By accepting delivery of this Warrant Certificate, the registered holder hereof covenants and agrees with the Issuer that no Warrant may be sold, assigned, conveyanced, pledged, hypothecated or in any other manner disposed of or transferred unless and until such holder shall deliver to the Issuer (i) written notice of such transfer and of the name and address of the transferee has been received by the Issuer; (ii) a written agreement of the transferee to comply with the terms of the Subscription Agreement and this Warrant Certificate and (iii) in the case of a transfer hereof prior to the expiration of the Restricted Period specified on the first page hereof, an opinion of counsel stating that such transferee is not a "U.S. Person" as defined in Regulation S under the Securities Act of 1933, as amended, and that such transfer is otherwise exempt from any registration requirements. 8. The Issuer will pay all documentary stamp taxes (if any) attributable to the issuance of Warrant Shares upon the exercise of the Warrant by the registered holder hereof; provided, however, that the Issuer shall not be required to pay any tax or taxes which may be payable in respect of any transfer involved in the registration of the Warrant Certificate or any certificates for Warrant Shares in a name other than that of the registered holder of the Warrant Certificate surrendered upon the exercise of a Warrant, and the Issuer shall not be required to issue or deliver the Warrant Certificate or certificates for Warrant Shares unless or until the person or persons requesting the issuance thereof shall have paid to the Issuer the amount of such tax or shall have established to the satisfaction of the Issuer that such tax has been paid. 9. In case this Warrant Certificate shall be mutilated, lost, stolen or destroyed, the Issuer may in its discretion issue in exchange and substitution for and upon cancellation of the mutilated Warrant Certificate, or in lieu of and substitution for the Warrant Certificate lost, stolen or destroyed, a new Warrant Certificate of like tenor, but only upon receipt of evidence reasonably satisfactory to the Issuer of such loss, theft or destruction of such Warrant Certificate and indemnity, if requested, satisfactory to it. Applicants for a substitute Warrant Certificate shall also comply with such other reasonable regulations and pay such other reasonable charges as the Issuer may prescribe. 10. The number of Warrant Shares issuable upon the exercise of the Warrant (the "Exercise Rate") and the terms and conditions of the Warrant are subject to adjustment by the Issuer, in consultation with the holder hereof, from time to time as follows: a. If the Issuer: (1) subdivides its outstanding shares of Common Stock into a greater number of shares; (2) combines its outstanding shares of Common Stock into a smaller number of shares; or (3) issues by reclassification of its Common Stock any shares of its Capital Stock (as defined below); then the Exercise Rate in effect immediately prior to such action shall be adjusted so that the registered holder hereof shall thereafter be entitled to receive upon exercise the number of shares of Common Stock or other Capital Stock of the Issuer which such holder would have owned immediately following such action if such holder had exercised the Warrant immediately prior to such action. As used herein the term "Capital Stock" means, with respect to any corporation, any and all shares, interest, rights to purchase, warrants, options, participations or other equivalents of or interests (however designated) in stock issued by that corporation. Such adjustment shall become effective simultaneously with the effective date of any subdivision, combination or reclassification. If, after an adjustment, the registered holder hereof would receive upon exercise shares of two or more classes of Capital Stock of the Issuer, the Exercise Rate shall thereafter be subject to adjustment upon the occurrence of an action taken with respect to each such class of Capital Stock as is contemplated hereby with respect to the Common Stock, on terms comparable to those applicable to Common Stock hereunder. b. Whenever the Exercise Rate is adjusted, the Issuer shall provide the notices required by paragraph 12 hereof. c. If: (1) the Issuer takes any action that would require an adjustment in the Exercise Rate pursuant to subparagraph (a) above; or (2) there is a liquidation or dissolution of the Issuer; then the Issuer shall mail to the registered holder hereof a notice stating the proposed effective date of a subdivision, combination, reclassification, consolidation, merger, transfer, lease, liquidation or dissolution, as the case may be. The Issuer shall mail the notice at least 15 days before such date. d. The Issuer covenants and agrees with the registered holder hereof not to consolidate or merge with or into, or transfer or lease all or substantially all its assets to, any person unless, at the option of the registered holder hereof, either: (1) on any date prior to the effective date of such consolidation, mer- ger, transfer or lease(the "Redemption Date"),the Issuer shall have redeemed the Warrant represented hereby by paying to such holder, upon surrender of this Warrant Certificate, a price (the Redemption Price"),agreed in good faith by the Board of Directors of the Issuer and such holder, representing (x) the fair market value of the Common Stock that would be issuable upon exercise of the Warrant as of the Redemption Date; (y) In the event the fair market value as determined in (x) above is less than $30.00 a share, the intrinsic time value of the warrant as of the Redemption Date, such intrinsic value when added to the fair market value shall not exceed $30.00 per share and (z) such other factors as the Board of Directors and such holder deem appropriate; provided, however, that in the event of any bona fide dispute between the Issuer and such holder as to the computation of such Redemption Price, such dispute shall be resolved through binding arbitration under the rules of the American Arbitration Associaton, with the arbitration panel consisting of persons familiar with the valuation of derivative securities and such panel being advised, as to such valuation issues, by an investment bank of nationally recognized standing, the costs thereof to be borne by the non-prevailing party; or (2) (a) such person shall expressly assume in writing all of the obligations of the Issuer under the Subscription Agreement and hereunder and deliver notice thereof to the registered holder hereof; and (b) upon consummation of such transaction, the Warrant shall automatically become exercisable for the kind and amount of securities, cash or other assets that the registered holder hereof would have owned immediately after the consolidation, merger, transfer or lease if such holder had exercised the Warrant immediately before the effective date of such transaction. e. After an adjustment to the Exercise Rate hereunder, any subsequent event requiring an adjustment hereunder shall cause an adjustment to the Exercise Rate as so adjusted. 11. Upon the issuance of any stock dividend or distribution of Common Stock pro rata to all holders of Common Stock, the registered holder hereof on the record date for such distribution shall be entitled to receive such dividend or distribution on the same terms as the holders of Common Stock upon exercise hereof. 12. Upon any adjustment of the Exercise Rate pursuant to paragraph 10, the Issuer shall promptly thereafter but in any event within 15 days following such adjustment (i) cause to be delivered to the registered holder hereof a certificate of its Chief Financial Officer setting forth the Exercise Rate after such adjustment and setting forth in reasonable detail the method of calculation and the facts upon which such calculations are based, which certificate shall be conclusive evidence of the correctness of the matters set forth therein, and (ii) cause to be delivered to the registered holder hereof at his or her address appearing on the Warrant Register written notice of such adjustments by first-class mail, postage prepaid. Where appropriate, such notice may be given in advance and included as part of the notice required to be mailed under the other provisions of this paragraph 12. In case: a. the Issuer shall authorize the issuance to all holders of shares of Common Stock of rights, options or warrants to subscribe for or purchase shares of Common Stock or of any other subscription rights or warrants; or b. of any consolidation or merger to which the Issuer is a party and for which approval of any shareholders of the Issuer is required, or of the conveyance or transfer of the properties and assets of the Issuer substantially as an entirety, or of any reclassification or change of Common Stock issuable upon exercise of the 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 of a tender offer or exchange offer for shares of Common Stock; or c. of the voluntary or involuntary dissolution, liquidation or winding up of the Issuer; or d. the Issuer proposes to take any action which would require an adjustment of the Exercise Rate pursuant to paragraph 10; then the Issuer shall cause to be given to the registered holder hereof at his or her address appearing on the Warrant Register, at least 20 days (or 10 days in any case specified in clauses (a) or (b) above) prior to the applicable record date hereinafter specified, or promptly in the case of events for which there is no record date, by first class mail, postage prepaid, a written notice stating (i) the date as of which the holders of record of shares of Common Stock to be entitled to receive any such rights, options, warrants or distribution are to be determined, or (ii) the initial expiration date set forth in any tender offer or exchange offer for shares of Common Stock, or (iii) the date on which any such reclassification, consolidation, merger, conveyance, transfer, dissolution, liquidation or winding up is expected to become effective or consummated, and the date as of which it is expected that holders of record of shares of Common Stock shall be entitled to exchange such shares for securities or other property, if any, deliverable upon such reclassification, consolidation, merger, conveyance, transfer, dissolution, liquidation or winding up. 13. The Issuer shall serve as warrant agent (the "Warrant Agent") under this Agreement. The Warrant Agent hereunder shall at all times maintain a register (the "Warrant Register") of the holders of Warrants. Upon 30 days' notice to the registered holder hereof, the Issuer may appoint a new Warrant Agent. Such new Warrant Agent shall be a corporation doing business under the laws of the United States or any state thereof, in good standing and having a combined capital and surplus of not less than $50,000,000. The combined capital and surplus of any such new Warrant Agent shall be deemed to be the combined capital and surplus as set forth in the most recent annual report of its condition published by such Warrant Agent prior to its appointment; provided that such reports are published at least annually pursuant to law or to the requirements of a federal or state supervising or examining authority. After acceptance in writing of such appointment by the new Warrant Agent, it shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named herein as the Warrant Agent, without any further assurance, conveyance, act or deed; but if for any reason it shall be reasonably necessary or expedient to execute and deliver any further assurance, conveyance, act or deed, the same shall be done at the expense of the Issuer and shall be legally and validly executed and delivered by the Issuer. Any corporation into which the Issuer or any new Warrant Agent may be merged or any corporation resulting from any consolidation to which the Issuer or any new Warrant Agent shall be a party or any corporation to which the Issuer or any new Warrant Agent transfers substantially all of its corporate trust or shareholders services business shall be a successor Warrant Agent under this Agreement without any further act; provided that such corporation (i) would be eligible for appointment as successor to the Warrant Agent under the provisions of this paragraph 13 or (ii) is a wholly owned subsidiary of the Warrant Agent. Any such successor Warrant Agent shall promptly cause notice of its succession as Warrant Agent to be mailed (by first class mail, postage prepaid) to the registered holder hereof at such holder's last address as shown on the Warrant Register. This Warrant Certificate shall not be valid unless signed by the Issuer.
