NOTES TO CONDENSED FINANCIAL STATEMENTS March 31, 1999 (Unaudited) 1. Basis of Presentation We are focused on the discovery, development, and marketing of novel, proprietary botanical dietary supplements derived from tropical plant sources. We intend to develop and commercialize our Shaman-branded products through our recently established botanicals division. We also have available for out-licensing a pipeline of botanical product candidates, as well as novel pharmaceutical products for major human diseases developed by isolating active compounds from tropical plants with a history of medicinal use. 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 adjustments) 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 our Annual Report on Form 10-K for the fiscal year ended December 31, 1998, filed with the Securities and Exchange Commission on March 31, 1999. Until December 1998, we were focused solely on developing pharmaceutical products derived from tropical plant sources. Our pharmaceutical business model was dependent upon our ability to launch our first pharmaceutical product in 1999. As a result of the U.S. Food and Drug Administration response to our proposed fast-track (single-pivotal trial) New Drug Application package for our leading pharmaceutical product candidate, SP-303/Provir, and insufficient resources to continue the costly process of conducting a second pivotal trial which would have created significant delays, we restructured our business to focus on the development and marketing of dietary supplements. These unaudited interim financial statements have been prepared assuming that we will continue as a going concern. We need substantial working capital to fund our operations. As of March 31, 1999, we had cash, cash equivalents and short-term investment balances of approximately $2.7 million. Our long-term capital requirements will depend on numerous factors, including among others, the extent and progress of additional development activities related to the botanicals products, the success of any marketing efforts related to the botanicals products, the success of any out-licensing efforts with respect to the pharmaceuticals programs, and the extent and timing of additional costs associated with patents and other intellectual property rights. Our projections show that cash on hand plus approximately $1.0 million under the Credit Agreement (see Note 3) will be sufficient to fund operations at the current level through mid-August, 1999. Unless we are successful in our efforts to sell or out-license our pharmaceutical products, or to sell or establish collaborative agreements to sell our botanical products, we will be unable to fund our current operations beyond mid-August, 1999. In addition, unless we are successful in our efforts to raise additional capital through our proposed rights offering or other offerings of equity securities, to sell or out-license our pharmaceutical products, or to sell or establish collaborative agreements to sell our botanical products, our cash resources will be used to satisfy our existing liabilities, and we will be unable to fund our operations, which may result in significant delay of our planned activities or the cessation of operations. Even if we are successful in these efforts to raise additional funds, such funds may not be adequate to fund our operations on a long-term basis. In addition, we may need additional capital to fund the redemption of our Series D Preferred Stock or to pay accumulated dividends. The delisting of our common stock from The Nasdaq National Market on February 2, 1999 constituted an optional redemption event for our Series D Preferred Stock. Since we do not have adequate resources to pay to redeem the Series D Preferred Stock, we have issued a notice to the holders of the Series D Preferred Stock as required under our charter that prevented the redemption of the Series D Preferred Stock. Under the terms of our charter, the effect of preventing this redemption event by issuing the notice was to increase the annual cumulative dividend payable to the Series 6 D Preferred Stock holders to $180 per share and to adjust the conversion price of the Series D Preferred Stock to 72% of the lowest trading price for a designated period prior to the conversion. The notice preventing the redemption of the Series D Preferred Stock will remain in effect for as long as our securities are not listed on any of The Nasdaq National Market, The Nasdaq SmallCap Market, the American Stock Exchange or the New York Stock Exchange. In connection with the issuance of such notice, we recorded a deemed dividend charge in the amount of $2,273,614 in the first quarter of 1999. We will need to obtain additional funding through public or private equity or debt financing, collaborative agreements or from other sources to continue our research and development activities, fund operating expenses and commercialize products. If we raise additional funds by issuing equity securities, current stockholders may experience significant dilution. If we obtain additional funds through collaborative agreements, we may be required to relinquish rights to certain of our technologies, product candidates, products or marketing territories that we would otherwise seek to develop or commercialize ourselves. We may be unable to obtain adequate financing on acceptable terms when needed. If we are unable to obtain adequate funds, we may be required to reduce significantly our spending and delay, scale back or eliminate one or more of our research, development, or commercialization programs, which would have a material adverse effect on our business, financial condition and results of operations. 2. Restructuring Expenses On February 1, 1999, we initiated a restructuring plan in which we closed down the operations of our pharmaceutical business. We now intend to out-license worldwide marketing rights to all our pharmaceutical compounds and will focus our efforts on the development and commercialization of botanical dietary supplements. The restructuring plan includes: cessation of pharmaceutical research and development activities and related operations; outlicensing of all of our current pharmaceutical research programs; reduction in force of approximately 60 employees (65% of workforce); sale or disposal of all of our fixed assets that are not needed for our botanicals business; and sub-leasing a portion of our facility. The termination of 60 employees occurred on February 1, 1999. The following table summarizes the Company's restructuring activities as of March 31, 1999. Total Restructuring Spending/ Balance at Category Charges Charges March 31, 1999 -------------- --------------- ----------- ---------------- (in thousands) Severance and related charges $ 467 $ 352 $ 115 Write-off impaired assets 122 122 0 Cancellation of contracts 1,200 0 1,200 Other 400 0 400 ------- ------- -------- $ 2,189 $ 474 $ 1,715 ======= ======= ======= In addition, we have approximately $969,000 recorded as deferred revenue which we have not yet earned. We are currently in negotiations with Lipha/Merck for the discontinuation of the research and development agreement. 3. Subsequent Events In April 1999, directors of our company holding stock options to purchase an aggregate of 3,634,345 shares of common stock agreed to surrender these options to us for cancellation. On April 5, 1999, we entered into a credit facility and note purchase agreement with certain investors, stockholders, key executives and members of the board of directors (the "Credit Agreement"), pursuant to which we may borrow approximately $1.0 million at any time commencing on May 14, 1999 and until the earlier of the completion of a registered public offering of our equity securities, or September 1, 1999 (the "Convertible Promissory Notes"). The Convertible Promissory Notes will be due and payable on the earlier of (i) 30 days subsequent to the completion of the public offering, or (ii) December 31, 1999. Interest on the Convertible Promissory Notes will accrue at an annual rate of 12%. The Convertible Promissory Notes, when issued, will be secured by certain assets of our company and will be convertible into shares of the class 7 and series of equity securities offered by us in the first registered public offering effected by us after the date of the Credit Agreement, or into common stock if no such offering occurs prior to December 31, 1999. In connection with the Credit Agreement, we issued warrants to purchase shares of the same class and series of equity securities as those into which the debt is convertible. The number of shares subject to these warrants is equal to 50% of the debt amount divided by the per share sale price of the shares sold in the public offering. These warrants are exercisable, on a cashless basis, commencing on April 5, 1999, and through the third anniversary date of the public offering. The conversion price of the Convertible Promissory Notes and the exercise price of the warrants is equal to the per share offering price in the public offering. If a public offering is not completed prior to December 31, 1999, then the conversion price of the Convertible Promissory Notes and the exercise price of the warrants will be the lower of $0.05 per share of our common stock, or 1/3 of the five-day weighted average trading price of our common stock for the period ending three trading days prior to conversion or exercise. In April 1999, we entered into an amendment agreement with an existing lender to permit the issuance by us of the Convertible Promissory Notes. In connection with the amendment, we issued a warrant to purchase shares of the class and series of equity securities offered by us in the first registered public offering effected by us after the date of the loan amendment, or into common stock if no such offering occurs prior to December 31, 1999. The number of shares subject to these warrants is equal to $592,685 divided by the per share sale price of the shares sold in the above offering. This warrant is exercisable, on a cashless basis, commencing on April 30, 1999 and through the seventh anniversary date of the earlier to occur of (i) December 31, 1999, or (ii) the date of the above offering. The per share exercise price will be equal to the per share offering price of the above offering, or, if no offering is completed by December 31, 1999, then the lower of $0.05 per share of our common stock, or 1/3 of the five-day weighted average trading price of our common stock for the period ending three trading days prior to conversion or exercise. In May 1999, we filed a Registration Statement on Form S-1 with the Securities and Exchange Commission in connection with a proposed rights offering. We intend to sell up to 7,500,000 shares of our Series R Convertible Preferred Stock at $2.00 per share to all persons who are owners of our common stock on the record date for the offering, which is anticipated to be immediately prior to the effective date of the registration statement and the commencement of the rights offering. Each share of Series R Preferred Stock will automatically convert on February 1, 2000 into shares of common stock at a conversion price equal to the lesser of (i) 10% of the average closing sales price of our common stock as reported on the OTC Bulletin Board for the 10 trading days ending three trading days prior to the effective date, or (ii) 10% of the average closing sales price of our common stock for the 10 trading days ending three trading days prior to February 1, 2000. 8 SHAMAN PHARMACEUTICALS, INC. Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations Overview We are focused on the discovery, development, and marketing of novel, proprietary botanical dietary supplements derived from tropical plant sources. We intend to develop and commercialize our Shaman-branded products through our recently established botanicals division. We also have available for out-licensing a pipeline of botanical product candidates, as well as novel pharmaceutical products for major human diseases developed by isolating active compounds from tropical plants with a history of medicinal use. Until December 1998, we were focused solely on developing pharmaceutical products derived from tropical plant sources. Our pharmaceutical business model was dependent upon our ability to launch our first pharmaceutical product in 1999. As a result of the U.S. Food and Drug Administration response to our proposed fast-track (single-pivotal trial) New Drug Application package for our leading pharmaceutical product candidate, SP-303/Provir, and insufficient resources to continue the costly process of conducting a second pivotal trial which would have created significant delays, we restructured our business to focus on the development and marketing of dietary supplements. Results of Operations for the Quarters Ended March 31, 1999 and 1998 The results of operations for the quarter ended March 31, 1998 relate to our pharmaceutical operations. Since we ceased operations of our pharmaceutical business and focused our efforts in our botanical business in February 1999, our results of operations for the quarter ended March 31, 1999 and future periods are not comparable to the same periods last year. We recorded collaborative revenues of $0 and $875,000 for the quarters ended March 31, 1999 and 1998, respectively. Revenues for the first quarter of 1998 resulted from research funding from Lipha S.A., a wholly-owned subsidiary of Merck KGaA, Darmstadt, Germany ("Lipha/Merck") and research funding from our collaboration with Ono Pharmaceutical Co. Ltd. of Osaka, Japan ("Ono"), which expired in May 1998. In December 1998, we renegotiated the terms of the existing agreement with Lipha/Merck. Under the new terms, we forgave $6.0 million in aggregate payments due over the remaining term of the original agreement in exchange for a one-time up-front payment of an aggregate of $2.0 million, consisting of a $1.0 million research payment (which remains recorded as deferred revenue that we have not yet earned) and a $1.0 million equity investment. We are currently in negotiations with Lipha/Merck for the discontinuation of this agreement. There will be no further research payments from Lipha/Merck. We incurred research and development expenses of $2.3 million of which $149,000 was related to the research and development of the botanicals division and $7.5 million for the quarters ended March 31, 1999 and 1998, respectively. This decrease was primarily attributable to the closing down of our pharmaceutical business as of February 1, 1999. Research and development expenses are expected to decrease in 1999 as we focus our efforts in our botanicals business, effective February 1, 1999. General and administrative expenses were $1.5 million and $1.3 million for the quarters ended March 31, 1999 and 1998, respectively. This increase was primarily attributable to legal dispute costs. General and administrative expenses are expected to decrease in 1999 since we have ceased operations in our pharmaceutical business and focused our efforts in our botanicals business, effective February 1, 1999. Interest income was $73,000 and $232,000 for the quarters ended March 31, 1999 and 1998, respectively. Interest income decreased for the period ended March 31, 1999, compared with the period ended March 31, 1998, due to lower average cash and investment balances as we continue to fund our operations. Interest expense was $259,000 and $807,000 for the quarters ended March 31, 1999 and 1998, respectively. Interest expense decreased for the period ended March 31, 1999, compared with the period ended March 31, 1998 due to lower average debt balances. 9 Delisting of our common stock from Nasdaq National Market The delisting of our common stock from The Nasdaq National Market on February 2, 1999 constituted an optional redemption event for our Series D Preferred Stock. Since we do not have adequate resources to pay to redeem the Series D Preferred Stock, we have issued a notice to the holders of the Series D Preferred Stock as required under our charter that prevented the redemption of the Series D Preferred Stock. Under the terms of our charter, the effect of preventing this redemption event by issuing the notice was to increase the annual cumulative dividend payable to the Series D Preferred Stock holders to $180 per share and to adjust the conversion price of the Series D Preferred Stock to 72% of the lowest trading price for a designated period prior to the conversion. The notice preventing the redemption of the Series D Preferred Stock will remain in effect for as long as our securities are not listed on any of The Nasdaq National Market, The Nasdaq SmallCap Market, the American Stock Exchange or the New York Stock Exchange. In connection with the issuance of such notice, we recorded a deemed dividend charge in the amount of $2,273,614 in the first quarter of 1999. Restructuring Expenses On February 1, 1999, we initiated a restructuring plan in which we closed down the operations of our pharmaceutical business. We now intend to out-license worldwide marketing rights to all our pharmaceutical compounds and will focus our efforts on the development and commercialization of botanical dietary supplements.

The termination of 60 employees occurred on February 1, 1999. The following table summarizes the Company's restructuring activities as of March 31, 1999. Total Restructuring Spending/ Balance at Category Charges Charges March 31, 1999 -------------- --------------- ----------- ---------------- (in thousands) Severance and related charges $ 467 $ 352 $ 115 Write-off impaired assets 122 122 0 Cancellation of contracts 1,200 0 1,200 Other 400 0 400 ------- ------- ------- $ 2,189 $ 474 $ 1,715 ======= ======= ======= In addition, we have approximately $969,000 recorded as deferred revenue for which we have not yet earned. We are currently in negotiations with Lipha/Merck for the discontinuation of the research and development agreement. Liquidity and Capital Resources As of March 31, 1999, our cash, cash equivalents, and investments totaled approximately $2.7 million, compared with $9.2 million at December 31, 1998. We invest excess cash according to our investment policy that provides guidelines with regard to liquidity, type of investment, credit ratings and concentration limits. 10 In April 1999, we entered into a credit facility and note purchase agreement with certain investors, stockholders, key executives and members of the board of directors (the "Credit Agreement"), pursuant to which we may borrow up to $1.0 million at any time commencing on May 14, 1999 and until the earlier of the completion of a registered public offering of our equity securities, or September 1, 1999 (the "Convertible Promissory Notes"). The Convertible Promissory Notes will be due and payable on the earlier of (i) 30 days subsequent to the completion of the public offering, or (ii) December 31, 1999. Interest on the Convertible Promissory Notes will accrue at an annual rate of 12%. The Convertible Promissory Notes, when issued, will be secured by certain assets of Shaman and will be convertible into shares of the class and series of equity securities offered by us in the first registered public offering effected by us after the date of the Credit Agreement, or into common stock if no such offering occurs prior to December 31, 1999. In connection with the Credit Agreement, we issued warrants to purchase shares of the same class and series of equity securities as those into which the debt is convertible. The number of shares subject to these warrants is equal to 50% of the debt amount divided by the per share sale price of the shares sold in the public offering. These warrants are exercisable, on a cashless basis, commencing on April 5, 1999, and through the third anniversary date of the public offering. The conversion price of the Convertible Promissory Notes and the exercise price of the warrants is equal to the per share offering price in the public offering. If a public offering is not completed prior to December 31, 1999, then the conversion price of the Convertible Promissory Notes and the exercise price of the warrants will be the lower of $0.05 per share of our common stock, or 1/3 of the five-day weighted average trading price of our common stock for the period ending three trading days prior to conversion or exercise. We have incurred substantial additional costs in the first quarter of 1999 relating to our restructuring in February 1999. We expect to continue to incur losses at least through 1999. We need substantial working capital to fund our operations. As of March 31, 1999, we had cash, cash equivalents and short-term investment balances of approximately $2.7 million. Our long-term capital requirements will depend on numerous factors, including among others, the extent and progress of additional development activities related to the botanicals products, the success of any marketing efforts related to the botanicals products, the success of any out-licensing efforts with respect to the pharmaceuticals programs, and the extent and timing of additional costs associated with patents and other intellectual property rights. Our projections show that cash on hand plus approximately $1.0 million under the Credit Agreement (see Note 3) will be sufficient to fund operations at the current level through mid-August, 1999. Unless we are successful in our efforts to sell or out-license our pharmaceutical products, or to sell or establish collaborative agreements to sell our botanical products, we will be unable to fund our current operations beyond mid-August, 1999. In addition, unless we are successful in our efforts to raise additional capital through our proposed rights offering or other offerings of equity securities, to sell or out-license our pharmaceutical products, or to sell or establish collaborative agreements to sell our botanical products, our cash resources will be used to satisfy our existing liabilities, and we will be unable to fund our operations, which may result in significant delay of our planned activities or the cessation of operations. Even if we are successful in these efforts to raise additional funds, such funds may not be adequate to fund our operations on a long-term basis. In addition, we may need additional capital to fund the redemption of our Series D Preferred Stock or to pay accumulated dividends. The delisting of our common stock from The Nasdaq National Market on February 2, 1999 constituted an optional redemption event for our Series D Preferred Stock. Since we do not have adequate resources to pay to redeem the Series D Preferred Stock, we have issued a notice to the holders of the Series D Preferred Stock as required under our charter that prevented the redemption of the Series D Preferred Stock. Under the terms of our charter, the effect of preventing this redemption event by issuing the notice was to increase the annual cumulative dividend payable to the Series D Preferred Stock holders to $180 per share and to adjust the conversion price of the Series D Preferred Stock to 72% of the lowest trading price for a designated period prior to the conversion. The notice preventing the redemption of the Series D Preferred Stock will remain in effect for as long as our securities are not listed on any of The Nasdaq National Market, The Nasdaq SmallCap Market, the American Stock Exchange or the New York Stock Exchange. In connection with the issuance of such notice, we recorded a deemed dividend charge in the amount of $2,273,614 in the first quarter of 1999. We will need to obtain additional funding through public or private equity or debt financing, collaborative agreements or from other sources to continue our research and development activities, fund operating expenses and prepare for commercialization of products. If we raise additional funds by issuing equity securities, current stockholders may experience significant dilution. If we obtain additional funds through collaborative agreements, we may be required to 11 relinquish rights to certain of our technologies, product candidates, products or marketing territories that we would otherwise seek to develop or commercialize ourselves. We may be unable to obtain adequate financing on acceptable terms when needed. If we are unable to obtain adequate funds, we may be required to reduce significantly our spending and delay, scale back or eliminate one or more of our research, development, or commercialization programs, which would have a material adverse effect on our business, financial condition and results of operations. Year 2000 Compliance The Year 2000 issue is the result of computer programs being written using two digits rather than four to define the applicable year. Any of our computer programs or hardware that have date-sensitive software or embedded chips may recognize a date using "00" as the year 1900 rather than the year 2000. This could result in a system failure or miscalculations causing disruptions of operations, including, among other things, a temporary inability to process transactions or engage in similar normal business activities. Based on recent assessments, we have determined that we will be required to certify portions of our software and certain hardware so that those systems will properly utilize dates beyond December 31, 1999. We presently believe that with modifications or replacements of existing software and certain hardware, the Year 2000 issue can be mitigated. We believe that such modification and replacements are not significant, and should such modification and replacements be delayed there would be no material impact on our operations. We are approximately 85% complete with the assessment of all internal systems that could be significantly affected by the Year 2000. To date, all assessments have been preformed by our employees, therefore, we have not incurred any costs related to this assessment project. We estimate that upgrades for those systems not in compliance will total approximately $200,000. After the assessment phase is completed, we will have to purchase, install and test the upgrades to ensure they meet internal Year 2000 compliance. We expect to complete our internal Year 2000 readiness program in the third quarter of 1999. We are also in the process of asking our significant suppliers and subcontractors that do not share information systems with us (external agents) whether their systems are Year 2000 compliant. To date, we are not aware of any external agent with a Year 2000 Issue that would materially impact our results of operations, liquidity, or capital resources. However, we have no means of ensuring that external agents will be Year 2000 ready. The inability of external agents to complete their Year 2000 resolutions to process in a timely fashion could materially impact us. We currently have no contingency plans in place in the event we do not complete all phases of the Year 2000 program. We plan to evaluate the status of completion in second quarter of 1999 and determine whether such a plan is necessary. Item 3. Quantitative and Qualitative Disclosures About Market Risks None. 12 Certain Factors that May Affect Future Results This Form 10-Q contains, in addition to historical information, forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, that involve risks and uncertainties. The Company's actual results could differ materially from the results discussed in the forward-looking statements. Factors that could cause or contribute to such differences include those discussed below and also in "Risk Factors," "Management's Discussion and Analysis of Financial Condition and Results of Operations," and elsewhere in our Form 10-K for the fiscal year ended December 31, 1998, filed with the Securities and Exchange Commission on March 31, 1999. We will need significant additional capital to fund continuing operations We need substantial working capital to fund our operations. As of March 31, 1999, we had cash, cash equivalents and short-term investment balances of approximately $2.7 million. Our long-term capital requirements will depend on numerous factors, including among others, the extent and progress of additional development activities related to the botanicals products, the success of any marketing efforts related to the botanicals products, the success of any out-licensing efforts with respect to the pharmaceuticals programs, and the extent and timing of additional costs associated with patents and other intellectual property rights. Our projections show that cash on hand plus approximately $1.0 million under the Credit Agreement (see Note 3) will be sufficient to fund operations at the current level through mid-August, 1999. Unless we are successful in our efforts to sell or out-license our pharmaceutical products, or to sell or establish collaborative agreements to sell our botanical products, we will be unable to fund our current operations beyond mid-August, 1999. In addition, unless we are successful in our efforts to raise additional capital through our proposed rights offering or other offerings of equity securities, to sell or out-license our pharmaceutical products, or to sell or establish collaborative agreements to sell our botanical products, our cash resources will be used to satisfy our existing liabilities, and we will be unable to fund our operations, which may result in significant delay of our planned activities or the cessation of operations. Even if we are successful in these efforts to raise additional funds, such funds may not be adequate to fund our operations on a long-term basis. In addition, we may need additional capital to fund the redemption of our Series D Preferred Stock or to pay accumulated dividends. The delisting of our common stock from The Nasdaq National Market on February 2, 1999 constituted an optional redemption event for our Series D Preferred Stock. Since we do not have adequate resources to pay to redeem the Series D Preferred Stock, we have issued a notice to the holders of the Series D Preferred Stock as required under our charter that prevented the redemption of the Series D Preferred Stock. Under the terms of our charter, the effect of preventing this redemption event by issuing the notice was to increase the annual cumulative dividend payable to the Series D Preferred Stock holders to $180 per share and to adjust the conversion price of the Series D Preferred Stock to 72% of the lowest trading price for a designated period prior to the conversion. The notice preventing the redemption of the Series D Preferred Stock will remain in effect for as long as our securities are not listed on any of The Nasdaq National Market, The Nasdaq SmallCap Market, the American Stock Exchange or the New York Stock Exchange. In connection with the issuance of such notice, we recorded a deemed dividend charge in the amount of $2,273,614 in the first quarter of 1999. We will need to obtain additional funding through public or private equity or debt financing, collaborative agreements or from other sources to continue our research and development activities, fund operating expenses and commercialize products. If we raise additional funds by issuing equity securities, current stockholders may experience significant dilution. If we obtain additional funds through collaborative agreements, we may be required to relinquish rights to certain of our technologies, product candidates, products or marketing territories that we would otherwise seek to develop or commercialize ourselves. We may be unable to obtain adequate financing on acceptable terms when needed. If we are unable to obtain adequate funds, we may be required to reduce significantly our spending and delay, scale back or eliminate one or more of our research, development, or commercialization programs, which would have a material adverse effect on our business, financial condition and results of operations. Possible inability to continue as a going concern increases investment risk We have suffered recurring and significant losses from operations. We have also relied upon debt and equity financing to fund these losses and cash flow deficits. Cash flows from future operations, if any, may not be sufficient to enable us to continue our current level of operations, or to meet our debts as they come due. As a result, we may not be able to continue as a going concern. For the year ended December 31, 1998, our independent auditors have issued a report which contains explanatory language for the uncertainty related to our ability to continue as a going concern beyond December 31, 1999. If we are to remain as a going concern, we will need to become and remain profitable and will also need additional financing. We may not be successful in obtaining new financing or in achieving profitability. 13 We have a history of operating losses, expect continuing losses and may never achieve profitability We have incurred significant operating losses in each year since our founding in 1989 and expect to continue to incur net losses for the foreseeable future. We incurred a net loss of approximately $6.3 million for the quarter ended March 31, 1999 and additional non-cash expense of $2.3 million incurred in connection with the issuance of the Control Notice to holders of Series D Preferred Stock. As of March 31, 1999, our accumulated deficit was approximately $159 million. If we are to become and remain profitable, we will need to, among other things, generate product revenues. We have not generated any product sales to date. We have changed the direction of our operations and are pursuing a new business model in the botanical dietary supplement industry. Our botanical dietary supplement products are being prepared for commercial introduction. In order to generate revenues or profits, we must successfully market these products or enter into collaborative agreements with others who can successfully market them. Even if our products are introduced, they may not achieve market acceptance or we may not achieve profitability. Our pharmaceutical product candidates and compounds are still in the research and development stage and we have ceased all our pharmaceutical operations. In order to generate revenues from these products, we must out-license these product candidates. It is possible that our out-licensing efforts may not be successful, and that we or our licensees may not obtain required regulatory approvals. Even if our product candidates are developed and introduced, they may not be successfully marketed and may not achieve market acceptance or we may not achieve profitability. The ownership interests of our common stockholders will be substantially reduced by future issuances of stock upon exercises and conversions of currently outstanding options, warrants and preferred stock We currently have outstanding many securities that are convertible into shares of common stock. The holders of common stock will be diluted upon the exercise of outstanding options and warrants and upon conversion of the Series A Preferred Stock, the Series C Preferred Stock and the Series D Preferred Stock. The Series D Preferred Stock is currently convertible into common stock at a price equal to 72% of the market price of the common stock, and commencing in August 1999, the Series C Preferred Stock will be convertible at a price equal to 85% of the market price of the common stock and may be freely resold on the market. The common stock issued upon conversion of the Series C and Series D Preferred Stock will substantially dilute the common stock and will likely depress the price of the common stock if large amounts are offered for sale in the open market. In our proposed rights offering, we intend to sell up to 7,500,000 shares of Series R Convertible Preferred Stock that will be convertible into shares of common stock at an effective per share price of 10% of the market price of the common stock. Any issuances of Series R Preferred Stock will therefore substantially dilute holders of common stock who do not participate. In addition, assuming the completion of the rights offering, there will be outstanding warrants to purchase 548,344 shares of Series R Preferred Stock. The exercise of these warrants and the sales of common stock underlying the Series R Preferred Stock will also dilute the common stock. We have no experience in the business of botanical dietary supplements and may not be successful in transitioning into this new business We are in the process of transitioning our operations from pharmaceutical product development to botanical dietary supplement development and commercialization. We have no experience in this new industry segment and must create a new business model. Some skills and relationships developed over time may not be transferable to our new business. While we have been working with natural products since our inception, we have no prior experience manufacturing or marketing dietary supplements. We may not be successful in these activities. Our botanical products are at various stages of development, ranging from initial research to final formulation. We will need to conduct additional research and development to move our product candidates toward commercialization. Our research and development efforts on potential products may not lead to development of products that we can successfully commercialize. In addition, we may not be able to produce our products in commercial quantities at acceptable costs, or to market and sell our products successfully. Our products may also prove to have undesirable or unintended side effects that may prevent or limit their commercial use. Accordingly, we may curtail, redirect, suspend or eliminate our product development or commercialization at any time. 14 The failure or loss of third parties on which we rely to manufacture our products and to perform other services could adversely affect our future operations and financial results We currently produce products only in pilot scale quantities and do not have the staff or facilities necessary to manufacture products in commercial quantities. Therefore, we must rely on collaborative partners or third party manufacturing facilities. We may not be successful in entering into third party manufacturing arrangements on acceptable terms, if at all. In addition, should we or our third party manufacturers encounter delays or difficulties in producing, packaging and distributing our finished products, our clinical trials and market introduction and subsequent sales of our products could be adversely affected. Contract manufacturers must conform to certain Good Manufacturing Practices regulations for foods on an ongoing basis. Our dependence on third parties for the manufacture of our products may adversely affect our ability to develop and deliver products on a timely and competitive basis. If we are required to manufacture our own products, we will be required to build or purchase a manufacturing facility, will be subject to manufacturing requirements and to similar risks regarding delays or difficulties encountered in manufacturing any such products, and we will require substantial additional capital. We may be unable to manufacture any such products successfully or in a cost-effective manner. We have only a limited marketing staff and may be unable to launch our products in the marketplace We currently have minimal marketing staff. If we are unable to successfully establish, execute and finance a complete marketing plan, we may not achieve a successful product entry into the marketplace. Such failure would have a material adverse effect on our business, financial condition and results of operations. Our success will depend on entering into strategic partnership relationships Our ability to develop, commercialize, market and sell our botanical supplement products will depend on our entering into strategic partner relationships. We are currently searching for strategic partners for development and commercialization. Our success in the botanicals market depends in part upon our ability to attract, retain and motivate key strategic partners in each major sales and distribution channel. We may not be successful in negotiating or entering into such agreements on terms favorable to us, or at all, and any agreement, if entered into, may be unsuccessful. We may never derive any significant revenues from any of our existing or future collaborations. We also intend to seek collaborative agreements to develop and commercialize our pharmaceutical product candidates. We may not be successful in negotiating or entering into such agreements on terms favorable to us or at all, and any agreement, if entered into, may be unsuccessful. We may incur costs in connection with the termination of prior research and development agreement The research and development efforts in our discontinued diabetes program were dependent upon arrangements with Lipha/Merck. We are currently in negotiations with Lipha/Merck for the discontinuation of their research agreement. Lipha/Merck will make no further research payments, and may have a claim against Shaman in connection with the termination of the agreement. We may never derive any significant revenues from any of our existing or future collaborations and may incur a loss in connection with the termination of existing collaborations. We are subject to intense competition in the botanical dietary supplement industry The dietary supplement business is highly competitive and is characterized by short product life cycles, significant pressure on pricing and heavy commitment of marketing resources. Many of our existing competitors are substantially larger and have greater financial, research and development, production, marketing, sales and other resources than we do. Such companies offer a variety of competitive products and services and much broader product lines. We face actual and potential competition not only from these established companies, but also from start-up companies developing and marketing new commercial products. Our failure to successfully compete for customers could adversely affect our future growth, revenues and profitability. 15 Government regulation The manufacturing, processing, formulating, packaging, labeling and advertising of our botanical dietary supplement products are subject to regulation in the United States by several federal agencies, including the Food and Drug Administration, the Federal Trade Commission, the Consumer Product Safety Commission, the Department of Agriculture and the Environmental Protection Agency. Our activities are also regulated by various agencies of the states and localities where we will distribute and sell our products. The composition and labeling of dietary supplements is most actively regulated by the FDA under the provisions of the Federal Food, Drug, and Cosmetic Act. The FFDC Act has been revised in recent years by the Nutrition Labeling and Education Act of 1990 and by the Dietary Supplement Health and Education Act of 1994. Our botanical product candidates are generally regulated as dietary supplements under the 1994 Dietary Supplement Health and Education Act, and are, therefore, generally not subject to pre-market approval by the FDA. However, these product candidates are subject to FDA regulation, particularly relating to adulteration and misbranding. For instance, we are responsible for ensuring that all dietary ingredients in a supplement are safe, and must notify the FDA in advance of putting a product containing a new dietary ingredient (i.e., an ingredient not marketed in the United States before October 15, 1994) on the market and furnish adequate information to provide reasonable assurance of the ingredient's safety. Currently, we are only pursuing products that are old dietary ingredients and are therefore not subject to this procedure. Further, if we make statements about a supplement's effects on the structure or function of the body, we must, among other things, substantiate that the statements are truthful and not misleading. In addition, our product labels must bear proper ingredient and nutritional labeling and we must manufacture our supplements in accordance with current Good Manufacturing Practices regulations for foods. A product can be removed from the market if it is shown to pose a significant or unreasonable risk of illness or injury. Moreover, if the FDA determines that the "intended use" of any of the our products is for the diagnosis, cure, mitigation, treatment or prevention of disease, the product would meet the definition of a drug and would require pre-market approval of safety and effectiveness prior to its manufacture and distribution. Our failure to comply with applicable FDA regulatory requirements may result in, among other things, injunctions, product withdrawals, recalls, product seizures, fines, and criminal prosecution. In March 1999, new FDA regulations governing the labeling of dietary supplements took effect. The new rules require that information such as the complete list of ingredients and levels of vitamins and minerals be included on product labels. While in our judgment these regulatory changes are generally favorable to the dietary supplements industry, in the future we may be subject to additional laws or regulations that could have an adverse effect on the industry and on our business. In addition, existing laws and regulations may be repealed and applicable regulatory authorities may interpret them stringently or unfavorably. We cannot predict the nature of future laws, regulations, interpretations or applications, nor can we determine what effect either additional government regulations or administrative orders, when and if promulgated, or disparate federal, state and local regulatory schemes would have on our business in the future. Any change could materially and adversely affect our results of operations and financial condition. Governmental regulations in foreign countries where we may commence or expand sales may prevent or delay entry into the market or prevent or delay the introduction, or require the reformulation, of our products. Compliance with such foreign governmental regulations is generally the responsibility of our partners or distributors in those countries, which distributors are independent contractors over whom we have limited or no control. Environmental regulation In connection with our research and development activities and manufacturing of materials, we are 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 we believe we comply with these laws and regulations in all material respects and have not been required to take any action to correct any noncompliance, we may be required to incur significant costs to comply with environmental and health and safety regulations in the future. Our research, development, and manufacturing activities involve the controlled use of hazardous materials and chemicals. Although we believe that our safety procedures for handling and disposing of such materials comply with the standards prescribed by state and federal regulations, we cannot eliminate the risk of accidental contamination or injury from these materials completely. In the event of an accident, we could be held liable for any resulting damages. Although we have secured insurance to mitigate such expense, any such liability could exceed our insurance coverage and resources. Such liability could have a material adverse effect on our business, financial condition and results of operations. 16 Product liability claims asserted against us in the future could adversely affect our business Our business exposes us to potential product liability risks that are inherent in the development, testing, manufacture, marketing and sale of pharmaceutical and dietary supplement products. Product liability insurance for the pharmaceutical and dietary supplement industries generally is expensive. Our present product liability insurance coverage, which includes coverage for acts by third parties, including manufacturers of our product candidates, may not be adequate. We will also need to increase our insurance coverage as we further develop our products, and we may be unable to obtain adequate insurance coverage against all potential claims at a reasonable cost. Some of our development and manufacturing agreements contain insurance and indemnification provisions pursuant to which we could be held accountable for certain occurrences. If we are subject to product liability claims for which we have inadequate insurance we could suffer a material adverse effect on our business, financial condition and results of operations. Negative publicity regarding the safety or quality of our products could adversely impact our business Because we depend on consumers' perception of the safety and quality of our products as well as similar products distributed by other companies (which may not adhere to the same quality standards as ours), if our products or a competitor's similar products were asserted to be harmful to consumers, our business could be adversely affected by that negative publicity. In addition, because we depend on perceptions, adverse publicity associated with illness or other adverse effects resulting from consumers' failure to use our products as we suggest, other misuse or abuse of our products or any similar products distributed by other companies could affect the market acceptance of our products and materially adversely affect our business. Furthermore, we believe the recent growth experienced by the nutritional supplement market is based in part on national media attention regarding recent scientific research suggesting potential health benefits from regular consumption of certain dietary supplements and other nutritional products. This research has been described in major medical journals, magazines, newspapers and television programs. The scientific research to date is preliminary, and in the future scientific results and media attention may contain unfavorable or inconsistent findings that could have a material adverse effect on our business. Our dependence on raw plant material from Latin and South America, Africa and Asia makes us particularly susceptible to the risks of interruptions in our supplies We currently import all of the plant materials for our products from countries in Latin and South America, Africa and Southeast Asia. We are dependent upon a supply of raw plant material to make our products. We do not have formal agreements in place with all of our suppliers. Continued source of plant supply risks include: * unexpected changes in regulatory requirements, * exchange rates, tariffs and barriers, * difficulties in coordinating and managing foreign operations, * political instability, and * potentially adverse tax consequences. Interruptions in supply or material increases in the cost of supply could have a material adverse effect on our business, financial condition and results of operations. If the prices of raw materials rise, we may not be able to raise prices quickly enough to offset the effect of these increased raw material costs, if at all. In addition, tropical rainforests and irreplaceable plant resources found only in such rainforests are currently threatened with destruction. The destruction of portions of the rainforests which contain the source material from which our current or future products are derived could materially and adversely affect our business, financial condition and results of operations. The failure to protect our intellectual property rights could adversely impact our business Our success will be substantially dependent on our proprietary technology. We rely primarily on a combination of patent, copyright and trademark laws, trade secrets, confidentiality procedures and contractual provisions to protect our intellectual property. These means of protecting our proprietary rights may not be adequate. Our trademarks are valuable assets that are very important to the marketing of our products. Our policy is to pursue registrations for all of the trademarks associated with our key products. We currently have 20 U.S. patents issued, 12 U.S. patent applications pending, and one international application filed. The pending patents may never be approved or issued. Any 17 issued patents may not provide sufficiently broad protection or may not prove valid or enforceable in actions against alleged infringers. Others may independently develop similar products, duplicate any of our products or design around any of our patents. In addition, many foreign countries may not protect our products and intellectual property rights to the same extent as the laws of the United States, and there is considerable variation between countries as to the level of protection afforded under patents and other proprietary rights. Such differences may expose Shaman to increased risks of commercialization in each foreign country in which we may sell products. We also depend on unpatented trade secrets. All of our employees have entered into confidentiality agreements. However, others may independently develop substantially equivalent information and techniques or otherwise gain access to our trade secrets, our trade secrets may be disclosed or we may be unable to effectively protect our rights to unpatented trade secrets. To the extent that we or our consultants or research collaborators use intellectual property owned by others in their work for us, disputes also may arise as to the rights in related or resulting know-how and inventions. Litigation may be necessary in the future to enforce our intellectual property rights, protect our trade secrets or to determine the validity and scope of the intellectual property rights of others. In the event of litigation to determine the validity of any third party's claims, we could be required to expend significant resources and divert the efforts of our technical and management personnel, whether or not such litigation is determined in our favor. Our success in outlicensing our pharmaceutical assets depends in large part on our ability to obtain and maintain patents, protect trade secrets and operate without infringing upon the proprietary rights of others. The patent position of companies in the pharmaceutical industry generally is highly uncertain, involves complex legal and factual questions, and has recently been the subject of much litigation. No consistent policy has emerged from the U.S. Patent and Trademark Office, or PTO, or the courts regarding the breadth of claims allowed or the degree of protection afforded under pharmaceutical patents. We are currently in a dispute in Europe regarding a patent for our proanthocyanidin polymer composition (which covers the active ingredient in SP-303/Provir). The European Patent Office, the French Patent Office, the German Patent Office and the Australian Patent Office have each granted a patent containing broad claims to proanthocyanidin polymer compositions (and methods of use of such compositions), which are similar to our specific composition, to Leon Cariel and the Institut des Substances Vegetales. The effective filing date of these patents is prior to the effective filing date of our foreign pending patent application in Europe. Certain of the foreign patents have been granted in jurisdictions where examination is not rigorous. We have instituted an Opposition in the European Patent Office against granted European Patent No. 472531 owned by Leon Cariel and Institut des Substances Vegetales. We believe that the granted claims are invalid and intend to vigorously prosecute the Opposition. In the United States, the Patent and Trademark Office awarded judgment to Shaman in an Interference regarding this patent dispute. We may be unsuccessful in having the granted European patent revoked or the claims sufficiently narrowed so that our proanthocyanidin polymer composition and methods of use are not potentially covered. The holders of the granted European patent may assert against us claims relating to this patent. If they are successful, we may not be able to obtain a license to this patent at all, or at reasonable cost, or be able to develop or obtain alternative technology to use in Europe or elsewhere. If we cannot obtain licenses to the patent, we may not be able to introduce or sell our SP-303/Provir product in Europe. The earlier effective filing date of this patent could limit the scope of the patents, if any, that we may be able to obtain or result in the denial of our patent applications in Europe or elsewhere. We may be subject to infringement claims by third parties The pharmaceutical industry and, to a lesser extent, the dietary supplement industry, is subject to frequent litigation regarding patent and other intellectual property rights. Leading companies and organizations in these industries have numerous patents that protect their intellectual property rights in these areas. Third parties may assert claims against us with respect to our existing and future products. In the event of litigation to determine the validity of any third party's claims, we could be required to expend significant resources and divert the efforts of our technical and management personnel, whether or not such litigation is determined in our favor. In the event of an adverse result of any such litigation, among other requirements, we could be required to develop non-infringing technology or to obtain licenses to the technology that is the subject of the litigation. We may not be successful in developing non-infringing technology or in obtaining a license to use the technology on commercially reasonable terms. We have no experience in marketing products over the Internet and may not succeed We intend to market our first product, SB-300, directly to consumers through the Internet on our web site. We have no experience in marketing any product on the Internet, and we have no market visibility or brand name 18 awareness on the Internet. Although Internet sites marketing dietary supplements do exist, the Internet may never develop as a strong or viable marketing and distribution channel for dietary supplements. We may not be successful in using the Internet as a direct marketing and distribution channel for our products. The failure of third party internet access providers to keep our web site operational could adversely affect our business We will rely entirely or in part on third parties to provide us with access to the Internet and to enable commerce over our web site, including providing adequate security of information provided over the web site. Any failure by such third party providers to provide uninterrupted access by our customers to our web site and to ensure that commerce can be conducted on our web site could have a material adverse effect on our business, financial condition and results of operations. We will only be able to execute our business plan if internet usage grows The success of our first product launch and a portion of our future business is highly dependent on the adoption of the Internet as a widely-used medium for commercial activities, including advertising, direct marketing and other commerce. The Internet market is at a very early stage of development, is rapidly evolving and is characterized by an increasing number of entrants that are introducing or developing competing products and services. The Internet has experienced, and is expected to continue to experience, significant growth in the number of users and amount of traffic. However, the Internet infrastructure may not be able to support the demands placed on it by this continued growth. In addition, the Internet could lose its viability due to delays in the development or adoption of new standards and protocols to handle increased levels of Internet activity or due to increased governmental regulation. Moreover, critical issues concerning the commercial use of the Internet, including security, reliability, cost, ease of use, accessibility and quality of service, remain unresolved. Such issues may negatively affect the growth of Internet use or the attractiveness of commerce and communication on the Internet. Our business, financial condition and operating results will be materially adversely affected if critical issues concerning the commercial use of the Internet are not favorably resolved, the necessary infrastructure is not developed, or the Internet does not become a viable commercial marketplace. Failure of the web infrastructure would harm our business The success of our first product launch and a portion of our future business will substantially depend, among other things, upon the continued expansion and maintenance of the web infrastructure as a reliable network backbone. This requires the necessary speed, capacity, security, and timely development of enabling products such as high speed modems, for providing reliable web access and services. We do not know whether the web infrastructure will continue to be able to support the growing demands placed upon it as the web continues to grow in terms of the number of users, the frequency of users and the increased bandwidth requirements. The performance or reliability of the web could be adversely affected by these demands. In addition, the Internet could lose its viability due to delays in the development or adoption of new standards and protocols required to handle increased levels of Internet activity or due to increased governmental regulation. Changes in, or insufficient availability of, telecommunications services to support the Internet could also result in slower response times and adversely affect usage of the web. The web has experienced a number of outages and other delays due to damage to portions of its web infrastructure. Any such outages or any other failure of the Internet infrastructure to effectively support the expected growth could delay the growth of the Internet and adversely affect our business. On-line security breaches could harm our business A significant barrier to electronic commerce and communications is the secure transmission of confidential information over public networks. We plan to rely on encryption and authentication technology licensed from third parties to provide the security and authentication necessary to effect secure transmission of confidential information to and from our web site. It is possible that advances in computer capabilities, new discoveries or other developments will result in a compromise or breach of the algorithms that we select for this purpose. This could have a material adverse effect on our business, results of operations and financial condition. We may be required to expend significant capital and other resources to protect against the threat of such security breaches or to alleviate problems caused by such breaches. The public's concern over the security of Internet transactions and the privacy of users may also inhibit the growth of the web as a means of conducting commercial transactions. To the extent that our activities or those of third party contractors involve the storage and transmission of proprietary information, such as credit card numbers, security breaches could expose us to a risk of loss or litigation and possible liability. Our security 19 measures may not be sufficient to prevent security breaches, and the failure to prevent such security breaches could have a material adverse effect on our business, results of operations and financial condition. Legal and regulatory uncertainties regarding the Internet could harm our business There is an increasing number of laws and regulations pertaining to the Internet. In addition, a number of legislative and regulatory proposals are under consideration by federal, state, local and foreign governments and agencies. Laws or regulations may be adopted with respect to the Internet relating to liability for information retrieved from or transmitted over the Internet, online content regulation, user privacy, taxation, pricing and quality of products and services. The growth and development of the market for online commerce may prompt more stringent consumer protection laws that may impose additional burdens on conducting business online. Moreover, the applicability to the Internet of existing laws governing issues such as intellectual property ownership and infringement, copyright, trademark, trade secret, obscenity, libel, employment and personal privacy is uncertain and developing. Any new legislation or regulation, or the application or interpretation of existing laws, may decrease the growth in the use of the Internet, increase our cost of doing business or otherwise have a material adverse effect on our business, operations and financial condition. In addition, since we expect that our products will be available over the Internet in multiple states, and as we expect to have consumers residing in such states, these jurisdictions may claim that we are required to qualify to do business as a foreign corporation in each such state. We are currently qualified to do business only in California, and failure to qualify as an out-of-state or foreign corporation in a jurisdiction where we are required to do so could subject us to taxes and penalties for the failure to qualify. Our executive officers and key personnel are critical to our business and may not remain with Shaman in the future Our success depends in large part upon the continued contributions of our key senior management. Our future performance also depends on our ability to attract and retain qualified management and scientific personnel. Competition for such personnel is intense, and we may be unable to continue to attract, assimilate or retain other highly qualified technical and management personnel in the future. The loss of key personnel or the failure to recruit additional personnel or to develop needed expertise could have a material adverse effect on our business, financial condition and results of operations. Potential Year 2000 computer software problems could adversely impact future operations The year 2000 issue is the result of computer programs being written using two digits rather than four to define the applicable year. Any of our computer programs or hardware that have date-sensitive software or embedded chips may recognize a date using "00" as the year 1900 rather than the year 2000. This could result in a system failure or miscalculations causing disruptions of operations, including, among other things, a temporary inability to process transactions or engage in similar normal business activities. Based on recent assessments, we have determined that we will be required to certify portions of our internal operating systems software and certain hardware so that those systems will properly utilize dates beyond December 31, 1999. We presently believe that with modifications or replacements of existing software and certain hardware, the year 2000 issue can be mitigated. We believe that such modification and replacements are not significant, and should such modification and replacements be delayed there would be no material impact on our operations. We cannot, however, be certain that we have identified all of the potential risks to our business that could result from matters related to the year 2000. We are approximately 85% complete with the assessment of all internal systems that could be significantly affected by the Year 2000. To date, all assessments have been preformed by our employees, therefore, we have not incurred any costs related to this assessment project. We estimate that upgrades for those systems not in compliance will total approximately $200,000. After the assessment phase is completed, we will have to purchase, install and test the upgrades to ensure they meet internal Year 2000 compliance. We expect to complete our internal Year 2000 readiness program in the third quarter of 1999. We are also in the process of asking our significant suppliers and subcontractors that do not share information systems with us (external agents) whether their systems are Year 2000 compliant. To date, we are not aware of any external agent with a Year 2000 Issue that would materially impact our results of operations, liquidity, or capital resources. However, we have no means of ensuring that external agents will be Year 2000 ready. The inability of external agents to complete their Year 2000 resolutions to process in a timely fashion could materially impact us. We currently have no contingency plans in place in the event we do not complete all phases of our year 2000 program. We plan to evaluate the status of completion in the second quarter of 1999 and determine whether such a plan is necessary. 20 The recent delisting from the Nasdaq National Market may reduce the liquidity and marketability of our stock and may depress the market price of our stock On February 2, 1999, Nasdaq delisted our common stock from The Nasdaq National Market and moved our stock to the National Association of Securities Dealers, Inc.'s OTC Bulletin Board. Although our securities are included on the OTC Bulletin Board, there can be no assurance that a regular trading market for the securities will be sustained in the future. The OTC Bulletin Board is an unorganized, inter-dealer, over-the-counter market which provides significantly less liquidity than The Nasdaq Stock Market, and quotes for stocks included on the OTC Bulletin Board are not listed in the financial sections of newspapers as are those for The Nasdaq Stock Market. Therefore, prices for securities traded solely on the OTC Bulletin Board may be difficult to obtain. The reduced liquidity of our stock and the reduced public access to quotations for our stock could depress the market price of our stock. "Penny Stock" regulations may impose restrictions on marketability of our stock The Securities and Exchange Commission has adopted regulations which generally define "penny stock" to be any equity security that is not traded on a national securities exchange or Nasdaq and that has a market price of less than $5.00 per share or an exercise price of less than $5.00 per share, subject to certain exceptions. Since our securities that are currently included on the OTC Bulletin Board are trading at less than $5.00 per share at any time, our stock may become subject to rules that impose additional sales practice requirements on broker-dealers who sell such securities to persons other than established customers and accredited investors (generally, such investors have assets in excess of $1,000,000 or an individual annual income exceeding $200,000, or, together with the investor's spouse, a joint income of $300,000). For transactions covered by these rules, the broker-dealer must make a special suitability determination for the purchase of such securities and have received the purchaser's written consent to the transaction prior to the purchase. Additionally, for any transaction involving a penny stock, unless exempt, the rules require, among other things, the delivery, prior to the transaction, of a risk disclosure document mandated by the SEC relating to the penny stock market and the risks associated therewith. The broker-dealer must also disclose the commission payable to both the broker-dealer and the registered representative, current quotations for the securities and, if the broker-dealer is the sole market-maker, the broker-dealer must disclose this fact and the broker-dealer's presumed control over the market. Finally, monthly statements must be sent disclosing recent price information for the penny stock held in the account and information on the limited market in penny stocks. Consequently, the penny stock rules may restrict the ability of broker-dealers to sell our securities and may affect the ability of stockholders to sell our securities in the secondary market. Our stock price has been and may continue to be highly volatile The price of our common stock has been particularly volatile and will likely continue to fluctuate in the future. Announcements of technological innovations, regulatory matters or new commercial products by us or our competitors, developments or disputes concerning patent or proprietary rights, publicity regarding actual or potential product results relating to products under development by us or our competitors, regulatory developments in both the United States and foreign countries, public concern as to the safety of pharmaceutical or dietary supplement products, and economic and other external factors, as well as period-to-period fluctuations in financial results, may have a significant impact on the market price of our common stock. In addition, from time to time, the stock market experiences significant price and volume fluctuations that may be unrelated to the operating performance of particular companies or industries. The market price of our common stock, like the stock prices of many publicly traded smaller companies, has been and may continue to be highly volatile. Anti-takeover Provisions in our Charter Documents and Delaware law may inhibit potential acquisition bids for Shaman, which may adversely affect the market price of our common stock and the voting rights of the holders of the common stock Certain provisions of our charter documents and Delaware law make it more difficult for a third party to acquire, and may discourage a third party from attempting to acquire, us, even if a change in control would be beneficial to our stockholders. These provisions could also limit the price that certain investors might be willing to pay in the future for shares of the common stock. The provisions include the division of our board of directors into two separate classes, the ability of the board to elect directors to fill vacancies created by an expansion of the board, the power of the board to amend our bylaws, and the requirement that at least 66 2/3% of the outstanding shares are required to call a special meeting of stockholders. Assuming the stockholders approve the amendment to our certificate of incorporation that are described in our proxy statement for the annual stockholders meeting to be held on June 11, 1999, our board will also have the authority to issue up to 11,393,715 additional shares of preferred stock, which includes 10,000,000 shares of Series R Preferred Stock that may be issued in our proposed rights offering and pursuant to exercise of warrants to purchase Series R Preferred Stock and to fix the price, rights, 21 preferences, privileges and restrictions of those shares without any further vote or action by the stockholders. The rights of the holders of common stock will be subject to, and may be adversely affected by, the rights of the holders of any preferred stock that may be issued in the future. The issuance of preferred stock with voting rights could make it more difficult for a third party to acquire a majority of the outstanding voting stock. Certain provisions of Delaware law applicable to us could also delay or make more difficult a merger, tender offer or proxy contest involving Shaman, including Section 203 of the Delaware General Corporation Law, which prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years unless certain conditions are met. 22 PART II OTHER INFORMATION Item 1. Legal Proceedings None. Item 2. Changes in Securities and Use of Proceeds None. Item 3. Defaults in Senior Securities None. Item 4. Submission of Matters to a Vote of Security Holders (a) A Special Meeting of Stockholders of Shaman Pharmaceuticals, Inc. was held on February 1, 1999. (b) The matters voted upon at the meeting and voting of the stockholders with respect thereto are as follows: (i) To approve an amendment and restatement to our Amended and Restated Certificate of Incorporation to (a) increase the number of authorized shares of our Common Stock thereunder from 40,000,000 shares to 70,0000,000 shares and (b) increase the number of authorized shares of our Preferred Stock by 1,000,000 shares, from 1,000,000 to 2,000,000 shares (This proposal was adjourned to March 8, 1999 at the February 1, 1999 Special Meeting of Stockholders.) For: 15,597,501 Against: 3,725,813 Abstain: 178,311 (ii) To approve an amendment to our 1992 Stock Option Plan (the "1992 Plan") to increase the maximum number of shares of our Common Stock authorized for issuance under the 1992 Plan by an additional 2,000,000 shares and change the limitation on the maximum number of shares for which any one individual may be granted stock options and separately exercisable stock appreciation rights under the Plan from 750,000 shares over the term of the 1992 Plan to 2,500,000 shares per calendar year. For: 11,394,957 Against: 3,836,201 Abstain: 440,538 (iii) To approve the option grant for 1,500,000 shares of our Common Stock made from the 1992 Plan to Lisa A. Conte, our President and Chief Executive Officer, on September 18, 1998 with an exercise price of $1.281 per share. For: 10,465,149 Against: 4,690,194 Abstain: 516,353 Item 5. Other information On April 5, 1999, we entered into a credit facility and note purchase agreement with certain investors, stockholders, key executives and members of the board of directors (the "Credit Agreement"), pursuant to which we may borrow approximately $1.0 million at any time commencing on May 14, 1999 and until the earlier of the completion of a registered public offering of our equity securities, or September 1, 1999 (the "Convertible Promissory Notes"). The Convertible Promissory Notes will be due and payable on the earlier of (i) 30 days subsequent to the completion of the public offering, or (ii) December 31, 1999. Interest on the Convertible Promissory Notes will accrue at an annual rate of 12%. The Convertible Promissory Notes, when issued, will be secured by certain assets of our company and will be convertible into shares of the class 23 and series of equity securities offered by us in the first registered public offering effected by us after the date of the Credit Agreement, or into common stock if no such offering occurs prior to December 31, 1999. In connection with the Credit Agreement, we issued warrants to purchase shares of the same class and series of equity securities as those into which the debt is convertible. The number of shares subject to these warrants is equal to 50% of the debt amount divided by the per share sale price of the shares sold in the public offering. These warrants are exercisable, on a cashless basis, commencing on April 5, 1999, and through the third anniversary date of the public offering. The conversion price of the Convertible Promissory Notes and the exercise price of the warrants is equal to the per share offering price in the public offering. If a public offering is not completed prior to December 31, 1999, then the conversion price of the Convertible Promissory Notes and the exercise price of the warrants will be the lower of $0.05 per share of our common stock, or 1/3 of the five-day weighted average trading price of our common stock for the period ending three trading days prior to conversion or exercise. In April 1999, we entered into an amendment agreement with an existing lender to permit the issuance by us of the Convertible Promissory Notes. In connection with the amendment, we issued a warrant to purchase shares of the class and series of equity securities offered by us in the first registered public offering effected by us after the date of the loan amendment, or into common stock if no such offering occurs prior to December 31, 1999. The number of shares subject to these warrants is equal to $592,685 divided by the per share sale price of the shares sold in the above offering. This warrant is exercisable, on a cashless basis, commencing on April 30, 1999 and through the seventh anniversary date of the earlier to occur of (i) December 31, 1999, or (ii) the date of the above offering. The per share exercise price will be equal to the per share offering price of the above offering, or, if no offering is completed by December 31, 1999, then the lower of $0.05 per share of our common stock, or 1/3 of the five-day weighted average trading price of our common stock for the period ending three trading days prior to conversion or exercise. In May 1999, we filed a Registration Statement on Form S-1 with the Securities and Exchange Commission in connection with a proposed rights offering. We intend to sell up to 7,500,000 shares of our Series R Convertible Preferred Stock at $2.00 per share to all persons who are owners of our common stock on the record date for the offering, which is anticipated to be immediately prior to the effective date of the registration statement and the commencement of the rights offering. Each share of Series R Preferred Stock will automatically convert on February 1, 2000 into shares of common stock at a conversion price equal to the lesser of (i) 10% of the average closing sales price of our common stock as reported on the OTC Bulletin Board for the 10 trading days ending three trading days prior to the effective date, or (ii) 10% of the average closing sales price of our common stock for the 10 trading days ending three trading days prior to February 1, 2000. 24 Item 6.

If the Company shall at any time prior to the expiration of this Warrant subdivide the class of securities then constituting Shares, by split-up or otherwise, or combine the equity securities constituting shares, or issue additional Shares or shares of its Common Stock as a dividend with respect to any of the Shares, the number of Shares issuable on the exercise of this Warrant shall forthwith be proportionately increased in the case of a subdivision or stock dividend, or proportionately decreased in the case of a combination. Appropriate adjustments shall also be made to the purchase price payable per Share, but the aggregate purchase price payable for the total number of Shares purchasable upon exercise of the then exercised portion of this Warrant (as adjusted) shall remain the same. Any adjustment under this Section 9(a) shall become effective as of the record date of such subdivision, combination or dividend, or in the event that no record date is fixed, upon the making of such subdivision, combination or dividend. (b) Reclassification, Reorganization and Consolidation. In case of any reclassification, capital reorganization, or change in the class of equity securities constituting the Shares (other than as a result of a subdivision, combination, or stock dividend provided for in Section 9(a) above), then, as a condition of such reclassification, reorganization, or change, lawful provision shall be made, and duly executed documents evidencing the same from the Company or its successor shall be delivered to the holder of this Warrant, so that the holder of this Warrant shall have the right at any time prior to the expiration of this Warrant to purchase, at a total price equal to that payable upon the exercise of the unexercised portion of this Warrant, the kind and amount of shares of stock and other securities and property receivable in connection with such reclassification, reorganization, or change by a holder of the same number of Shares as were purchasable by the holder of this Warrant immediately prior to such reclassification, reorganization, or change. In any such case appropriate provisions shall be made with respect to the rights and interest of the holder of this Warrant so that the provisions hereof shall thereafter be applicable with respect to any shares of stock or other securities and property deliverable upon exercise hereof, and appropriate adjustments shall be made to the purchase price per share payable hereunder, provided the aggregate purchase price shall remain the same. 3 (c) Notice of Adjustment. When any adjustment is required to be made in the number or kind of shares purchasable upon exercise of the Warrant, or in the Exercise Price, the Company shall within fifteen (15) days after such adjustment notify the holder of such event and of the number of shares of the Shares or other securities or property thereafter purchasable upon exercise of this Warrant; provided, however, that nothing in this Section 9(c) shall relieve the Company of its obligation to notify the Holder as provided in section 4 above. 10. No Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this Warrant, instead, the Company shall round all fractions up to the nearest whole share. 11. No Stockholder Rights. Prior to exercise of this Warrant, the holder shall not be entitled to any rights of a stockholder with respect to the Shares, including (without limitation) the right to vote such Shares, receive dividends or other distributions thereon, exercise preemptive rights or be notified of stockholder meetings, and the holder, as such, shall not be entitled to any notice or other communication concerning the business or affairs of the Company. 12.

The Company may not assign its obligations under this Warrant, except to an entity succeeding to substantially all of the business or assets of the Company. This Warrant is not transferable by Holder except by operation of law. Any purported transfer hereof (other than by operation of law) shall be null and void and the Company is hereby expressly authorized to instruct its transfer agent (which may be the Company itself) to not honor any such purported transfer. 13.

REGISTRATION RIGHTS;. (a) Mandatory Registration. (1) The Company shall prepare and not later than the Closing Date, file with the SEC a Registration Statement on Form S-3 which on the SEC Filing Date covers the resale of a number of shares of Common Stock equal to at least the number of shares of Common Stock as are then expected to be issuable upon a conversion of the Shares into shares of Common Stock (or as may hereafter become issuable upon conversion of the Notes, if the Offering is not completed by December 31, 1999), as Registrable Securities, and which Registration Statement shall state that, in accordance with Rule 416 under the 1933 Act, such Registration Statement also covers such indeterminate number of additional shares of Common Stock as may become issuable upon conversion of the Shares to prevent dilution resulting from stock splits, stock dividends or similar transactions.

The Company's obligation to register the Registrable Securities under this Section 8 shall constitute a registration pursuant to a demand registration right held by the Investors.

The Company shall submit to the SEC, within three Business Days after the Company learns that no review of the Registration Statement will be made by the staff of the SEC or that the staff of the SEC has no further comments on the Registration Statement, as the case may be, a request for acceleration of effectiveness of the Registration Statement to a time and date not later than 48 hours after the submission of such request. The Company represents and warrants to the Investors that (a) the Registration Statement (including any amendments or supplements thereto and prospectuses contained therein), at the time it is first filed with the SEC, at the time it is ordered effective by the SEC and at all times during which it is required to be effective hereunder (and each such amendment and supplement at the time it is filed with the SEC and at all times during which it is available for use in connection with the offer and sale of the Registrable Securities) shall not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading and (b) the Prospectus shall not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein, or 13 necessary to make the statements therein, in light of the circumstances in which they were made, not misleading; (2) prepare and file with the SEC such amendments (including post-effective amendments) and supplements to the Registration Statement and the Prospectus as may be necessary to keep the Registration Statement effective, and the Prospectus current, at all times during the Registration Period, and, during the Registration Period, comply with the provisions of the 1933 Act applicable to the Company in order to permit the disposition by the Investors of all Registrable Securities covered by the Registration Statement; (3) furnish to each Investor whose Registrable Securities are included in the Registration Statement and its legal counsel, (1) promptly after the same is prepared and publicly distributed, filed with the SEC or received by the Company, one copy of the Registration Statement and any amendment thereto, each Prospectus and each amendment or supplement thereto, (2) each letter written by or on behalf of the Company to the SEC or the staff of the SEC and each item of correspondence from the SEC or the staff of the SEC relating to such Registration Statement (other than any portion of any thereof which contains information for which the Company has sought confidential treatment), each of which the Company hereby determines to be confidential information and which the Buyer hereby agrees to keep confidential as a confidential Record in accordance with Section 8(b)(9) and (3) such number of copies of a Prospectus and all amendments and supplements thereto and such other documents, as such Investor may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such Investor;

provided, however, that the Company shall not be required in connection therewith or as a condition thereto (I) to qualify to do business in any jurisdiction where it would not otherwise be required to qualify but for this Section 8(b)(4), (II) to subject itself to general taxation in any such jurisdiction, (III) to file a general consent to service of process in any such jurisdiction, (IV) to provide any undertakings that cause more than nominal expense or burden to the Company or (V) to make any change in its charter or by-laws which the Board of Directors of the Company determines to be contrary to the best interests of the Company and its stockholders; (5) (A) as promptly as practicable after becoming aware of such event or circumstance, notify each Investor of any event or circumstance of which the Company has knowledge, as a result of which the Prospectus included in the Registration Statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, and use its best efforts promptly to prepare a supplement or amendment to the Registration Statement and Prospectus to correct such untrue statement or omission or to add any new or additional information, and deliver a number of copies of such supplement or amendment to each Investor as such Investor may reasonably request; 14 (B) notwithstanding Section 8(b)(5)(A) above, if at any time the Company notifies the Investors as contemplated by Section 8(b)(5)(A) that the event giving rise to such notice relates to a development involving the Company which occurred subsequent to the later of (x) the SEC Effective Date and (y) the latest date prior to such notice on which the Company has amended or supplemented the Registration Statement, then the Company shall not be required to use best efforts to make such amendment during a Blackout Period;

The Company shall not be required to disclose any confidential information in such 15 Records to any Inspector until and unless such Inspector shall have entered into confidentiality agreements (in form and substance satisfactory to the Company) with the Company with respect thereto, substantially in the form of this Section 8(b)(9). Each Investor agrees that it shall, upon learning that disclosure of such Records is sought in or by a court or governmental body of competent jurisdiction or through other means, give prompt notice to the Company and allow the Company, at the Company's expense, to undertake appropriate action to prevent disclosure of, or to obtain a protective order for, the Records deemed confidential.

Subject to the restrictions set forth in Section 8(e)(3) with respect to the number of legal counsel, the Company shall reimburse the Investors and each such controlling person, promptly as such expenses are incurred and are due and payable, for any reasonable legal fees or other expenses incurred by them in connection with investigating or defending any such Claim. Notwithstanding anything to the contrary contained herein, the indemnification agreement contained in this Section 8(e)(1) shall not apply to: (I) a Claim arising out of or based upon a Violation which occurs in reliance upon and in conformity with information relating to an Indemnified Person furnished in writing to the Company by any Indemnified Person or underwriter for such Indemnified Person expressly for use in connection with the preparation of the Registration Statement or any such amendment thereof or supplement thereto, if such Prospectus was timely made available by the Company pursuant to Section 8(b)(3) hereof; (II) an Indemnified Person with respect to a Claim which arises solely from the failure of such Indemnified Person to comply in any material respect with Section 8(c)(4); and (III) amounts paid in settlement of any Claim if such settlement is effected without the prior written consent of the Company. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Indemnified Person and shall survive the transfer of the Registrable Securities by the Investors. 18 (2) In connection with the Registration Statement, each Investor agrees to indemnify and hold harmless, to the same extent and in the same manner set forth in Section 8(e)(1), each Indemnified Party against any Claim to which any of them may become subject, under the 1933 Act, the 1934 Act or otherwise, insofar as such Claim arises out of or is based upon any Violation, in each case to the extent (and only to the extent) that such Violation occurs (A) in reliance upon and in conformity with written information furnished to the Company by such Investor expressly for use in connection with such Registration Statement or (B) the failure of such Indemnified Person to comply in any material respect with Section 8(c)(4); and such Investor will reimburse any legal or other expenses reasonably incurred by them in connection with investigating or defending any such Claim; provided, however, that the indemnity agreement contained in this Section 8(e)(2) shall not apply to amounts paid in settlement of any Claim if such settlement is effected without the prior written consent of such Investor, which consent shall not be unreasonably withheld; provided, further, however, that the Investor shall be liable under this Section 8(e)(2) for only that amount of a Claim as does not exceed the proceeds to such Investor as a result of the sale of Registrable Securities pursuant to such Registration Statement. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Indemnified Party and shall survive the transfer of the Registrable Securities by the Investors. Notwithstanding anything to the contrary contained herein, the indemnification agreement contained in this Section 8(e)(2) with respect to any preliminary prospectus shall not inure to the benefit of any Indemnified Party if the untrue statement or omission of material fact contained in the preliminary prospectus was corrected on a timely basis in the Prospectus, as then amended or supplemented. (3) Promptly after receipt by an Indemnified Person or Indemnified Party under this Section 8(e) of notice of the commencement of any action (including any governmental action), such Indemnified Person or Indemnified Party shall, if a Claim in respect thereof is to be made against any indemnifying party under this Section 8(e), deliver to the indemnifying party a written notice of the commencement thereof and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume control of the defense thereof with counsel reasonably satisfactory to the Indemnified Person or the Indemnified Party, as the case may be; provided, however, that an Indemnified Person or Indemnified Party shall have the right to retain its own counsel with the fees and expenses to be paid by the indemnifying party, if, in the reasonable opinion of counsel retained by the indemnifying party, the representation by such counsel of the Indemnified Person or Indemnified Party and the indemnifying party would be inappropriate due to actual or potential differing interests between such Indemnified Person or Indemnified Party and any other party represented by such counsel in such proceeding. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action shall not relieve such indemnifying party of any liability to the Indemnified Person or Indemnified Party under this Section 8(e), except to the extent that the indemnifying party is prejudiced in its ability to defend such action. The indemnification required by this Section 8(e) shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as such expense, loss, damage or liability is incurred and is due and payable. (f) Contribution;. To the extent any indemnification by an indemnifying party as set forth in Section 8(e) above is applicable by its terms but is prohibited or limited by law, the indemnifying party agrees to make the 19 maximum contribution with respect to any amounts for which it would otherwise be liable under Section 8(e) to the fullest extent permitted by law. In determining the amount of contribution to which the respective parties are entitled, there shall be considered the relative fault of each party, the parties' relative knowledge of and access to information concerning the matter with respect to which the claim was asserted, the opportunity to correct and prevent any statement or omission and any other equitable considerations appropriate under the circumstances; provided, however, that (a) no contribution shall be made under circumstances where the maker would not have been liable for indemnification under the fault standards set forth in Section 8(e), (b) no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any other person who was not guilty of such fraudulent misrepresentation and (c) contribution by any seller of Registrable Securities shall be limited to the amount of the proceeds received by such seller from the sale of such Registrable Securities (g) Reports under 1934 Act;. With a view to making available to the Investors the benefits of Rule 144, the Company agrees: (a) to promptly furnish to each Investor so long as such Investor owns Registrable Securities, such information as may be necessary to permit the Investors to sell Registrable Securities pursuant to Rule 144 without registration; and (b) if at any time the Company is not required to file such reports with the SEC under Sections 13 or 15(d) of the 1934 Act, to use its best efforts to, upon the request of an Investor, make publicly available other information so long as is necessary to permit publication by brokers and dealers of quotations for the Common Stock and sales of the Registrable Securities in accordance with Rule 15c2-11 under the 1934 Act. 9.MISCELLANEOUS.

The Debtor and the Investors will hold the Collateral Agent harmless from, and indemnify against, all loss, cost or expense (including attorney fees and settlement payments) which may be incurred by the Collateral Agent by reason of any claim or cause of action arising from or relating to the performance of the duties at any time as Collateral Agent, whether or not those claims or causes of action relate to actions or events occurring during the actual service as Collateral Agent in effect under this Agreement, unless the Collateral Agent is adjudged by a court of final appeal to have engaged in willful misconduct in connection with the subject matter of such claim or cause of action. SECTION 9 Remedies. (a) Upon the occurrence and continuance of any Event of Default, the Investors may declare any of the Obligations to be immediately due and payable and shall have, in addition to all other rights and remedies granted to it in 7 this Agreement or any other Transaction Document, all rights and remedies of a secured party under the UCC and other applicable laws. Without limiting the generality of the foregoing, the Collateral Agent, in each case as directed by the Majority Investors may sell, resell, lease, use, assign, license, sublicense, transfer or otherwise dispose of any or all of the Collateral in its then condition or following any commercially reasonable preparation or processing (utilizing in connection therewith any of Debtor's assets, without charge or liability to the Investors therefor) at public or private sale, by one or more contracts, in one or more parcels, at the same or different times, for cash or credit, or for future delivery without assumption of any credit risk, all as the Investors deem advisable; provided, however, that Debtor shall be credited with the net proceeds of sale only when such proceeds are finally collected by the Collateral Agent or the Investors. The Collateral Agent or the Investors shall have the right upon any such public sale, and, to the extent permitted by law, upon any such private sale, to purchase the whole or any part of the Collateral so sold, free of any right or equity of redemption, which right or equity of redemption Debtor hereby releases, to the extent permitted by law. Debtor hereby agrees that the sending of notice by ordinary mail, postage prepaid, to the address of Debtor set forth herein, of the place and time of any public sale or of the time after which any private sale or other intended disposition is to be made, shall be deemed reasonable notice thereof if such notice is sent five days prior to the date of such sale or other disposition or the date on or after which such sale or other disposition may occur, provided that the Collateral Agent or the Investors may provide Debtor shorter notice or no notice, to the extent permitted by the UCC or other applicable law. (b) The cash proceeds actually received from the sale or other disposition or collection of Collateral, and any other amounts received in respect of the Collateral the application of which is not otherwise provided for herein, shall be applied first, to the payment of the reasonable costs and expenses of the Collateral Agent and Investors in exercising or enforcing its rights hereunder and in collecting or attempting to collect any of the Collateral, and to the payment of all other amounts payable to the Investors pursuant to Section 12 hereof; and second, to the payment of the Obligations. Any surplus thereof which exists after payment and performance in full of the Obligations shall be promptly paid over to Debtor or otherwise disposed of in accordance with the UCC or other applicable law. Debtor shall remain liable to the Investors for any deficiency which exists after any sale or other disposition or collection of Collateral. SECTION 10 Certain Waivers. Debtor waives, to the fullest extent permitted by law, (i) any right of redemption with respect to the Collateral, whether before or after sale hereunder; (ii) any right to require the Collateral Agent or the Investors (A) to proceed against any Person, (B) to exhaust any other collateral or security for any of the Obligations, (C) to pursue any remedy in the Collateral Agent's or the Investors's power, or (D) to make or give any presentments, demands for performance, notices of nonperformance, protests, notices of protests or notices of dishonor in connection with any of the Collateral; and (iii) all claims, damages, and demands against the Collateral Agent or the Investors arising out of any lawful repossession, retention, sale or application of the proceeds of any sale of the Collateral. SECTION 11 Notices. All notices or other communications hereunder shall be in writing (including by facsimile transmission) and mailed, sent or delivered to the respective parties hereto at or to their respective addresses or facsimile numbers set forth below their names on the signature pages hereof, 8 or at or to such other address or facsimile number as shall be designated by any party in a written notice to the other parties hereto. All such notices and other communications shall be effective (i) if delivered by hand, when delivered; (ii) if sent by mail, upon the earlier of the date of receipt or 5 days after deposit in U.S. mail, first class; and (iii) if sent by facsimile transmission (with hard copy to follow promptly), when sent. SECTION 12 No Waiver; Cumulative Remedies. No failure on the part of the Collateral Agent or the Investors to exercise, and no delay in exercising, any right, remedy, power or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, remedy, power or privilege preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege. The rights and remedies under this Agreement are cumulative and not exclusive of any rights, remedies, powers and privileges that may otherwise be available to the Collateral Agent or the Investors. SECTION 13 Binding Effect. This Agreement shall be binding upon, inure to the benefit of and be enforceable by Debtor, the Collateral Agent, the Investors and their respective successors and assigns. This Agreement shall not be amended without the written consent of the Majority Investors. SECTION 14 Governing Law and Legal Actions. This Agreement shall be governed by and construed under the laws of California without regard to conflicts of laws provisions thereof. All parties consent to the jurisdiction of courts in the Northern and Southern Districts of California and agree that process may be served in the manner provided herein for giving of notices or otherwise as allowed by law. In any action or proceeding to enforce rights under this Agreement, the prevailing party shall be entitled to recover costs and attorneys' fees. SECTION 15 Entire Agreement. This Agreement and the Credit Facility and Note Purchase Agreement supersede all proposals, oral or written, all negotiations, conversations, or discussions between or among the parties relating to the subject matter of this Agreement and all past dealings or industry custom. SECTION 16 Severability. Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under all applicable laws and regulations. If, however, any provision of this Agreement shall be prohibited by or invalid under any such law or regulation in any jurisdiction, it shall, as to such jurisdiction, be deemed modified to conform to the minimum requirements of such law or regulation, or, if for any reason it is not deemed so modified, it shall be ineffective and invalid only to the extent of such prohibition or invalidity without affecting the remaining provisions of this Agreement, or the validity or effectiveness of such provision in any other jurisdiction. SECTION 17 Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute but one and the same agreement. Counterparts may be delivered by facsimile transmission, which delivery shall be conclusive notwithstanding any failure to deliver the original faxed counterpart. 9 SECTION 18 Termination. Upon payment and performance in full of all Obligations, this Agreement shall terminate and the Investors shall promptly execute and deliver to Debtor such documents and instruments reasonably requested by Debtor as shall be necessary to evidence termination of all security interests given by Debtor to the Investors hereunder; provided, however, that the obligations of Debtor under Sections 11 and 17 hereof shall survive such termination.
