Our Business, Strategy and Products We are focused on the discovery, development, and marketing of novel, proprietary botanical dietary supplements derived from tropical plant sources. We intend to implement our commercialization efforts through our recently established botanicals division, which we have named ShamanBotanicals.com. Our commercialization plan includes the use of community building initiatives on the Internet and other distribution channels, and is based on marketing our exclusive access to our proprietary branded products. We also have available for out-licensing a pipeline of botanical product candidates, as well as novel pharmaceutical product candidates for major human diseases developed by isolating active compounds from tropical plants with a history of medicinal use. In 1997, the U.S. dietary supplement market was $12.9 billion, of which over $4.0 billion was comprised of herbal or botanical dietary supplements. In 1998, this number was projected to reach $5.0 billion, with a compounded yearly growth rate of approximately 35%. In 1997, 24% of people within U.S. households reported using botanical dietary supplements. The growth of this market has been led by consumers who are interested in complementary, non-pharmaceutical options for treating symptoms, fulfilling unmet dietary needs, and optimizing health, either as an alternative to, or in conjunction with, more conventional medical approaches. We believe that the use of these products will continue to expand based upon the aging of the U.S. population, increasing scientific evidence and acceptance by the conventional medical establishment, and the recent entrance of powerful consumer companies which provide greater product confidence, while broadening the base of consumer users. The unique positioning of our botanicals business stems from our significant financial investment in our prior pharmaceutical product candidates, more than 10 years of extensive field research by our teams of ethnobotanists and physicians, and pharmaceutical-level chemical standardization, and biological and clinical testing. We are applying this methodology to our new industry, and we intend to set a new standard in this industry. In the last decade, we have amassed a large body of information on the health benefits of thousands of tropical plant species that have a history of human use and have organized this information into an extensive relational database. This database includes information on over 2,600 tropical plants, many of which have not been introduced or fully developed in the U.S. dietary supplement market. We have identified plants with a documented ethnomedical history of use in our library and database of botanicals for use in key market categories with significant commercial potential. Because many of these plants reflect the previously untapped plant diversity of the rainforests, many represent novel botanical products that we believe present an opportunity to attain a strong, proprietary market position. We currently have a fully-developed product, SB-300, and we expect to commercialize this product in the near future by applying the funds raised in this rights offering and raised through partnering development agreements we are working to put in place. We have the opportunity to differentiate our product candidates in consumers' minds relative to those of our competitors. Key points of differentiation include: * Novel plants/products for unmet needs; * Documented, first-hand field experience with traditional use; * Rainforest-based plants and products, since most botanical supplements products currently come from plants found in temperate areas; * Our commitment to conservation and reciprocity; * Sustainable sourcing and supply; * Quality manufactured, standardized products; and * Clinically-tested products. Our commercialization strategy is to create high-end branding of the Shaman name on our propriety products addressing serious unmet healthcare concerns, and to market these proprietary products to specific communities affected by such healthcare issues. Our e-commerce web site, ShamanBotanicals.com, which is currently under construction, will be designed to include several distinct features, such as exclusive access to our proprietary products, and links to peer-reviewed clinical data supporting the clinical action of our products. We also intend to offer access to certain medical 4 experts, in some cases exclusively, for medical commentary. Other planned features of our web site include bulletin board postings, community chat rooms, customer security and customization, and affiliate programs. Finally, information on our reciprocity programs will be available as well. Our first product launch will be SB-300, a botanical dietary supplement to normalize water flow in the bowel and promote stool formation. SB-300 will initially be targeted to people with AIDS/HIV who suffer from chronic diarrhea. We plan to market SB-300 via the Internet, 1-800 direct response advertising, limited storefront access in major market cities, and focused mail order opportunities. In addition, we are working with several leading treatment activists to have them feature the introduction of this product in their regional organizations' newsletters. We expect to begin marketing SB-300 commencing in the third quarter of 1999. Commencing fourth quarter of 1999, we also intend to market SB-300 to travelers and others suffering from acute episodes of diarrhea. The product will be differentiated from that targeted to the AIDS/HIV community in that it will be a lower dose and packaged in smaller quantities to address the nature of its expected use in the target customer base. We believe that selling a traveler's health-related product on the Internet presents an attractive marketing opportunity since two primary uses of the Internet are currently healthcare information and travel. We intend to market this product with banner advertising at affiliate travel sites and point of purchase at high-risk diarrhea destinations, sample programs to adventure travel and tour companies traveling to such areas, and other highly focused target customer programs. We are also working to develop a second product line based on a diet system to mitigate Syndrome X symptoms. Syndrome X is the cluster of metabolic disorders that occur in the face of elevated insulin when an individual is insulin resistant, yet still maintains glucose control and is therefore not diabetic. This cluster of coronary heart disease risk factors, such as elevated triglycerides and lower HDL-cholesterol, the "good" cholesterol, are the silent killers associated with Syndrome X. Shaman's Sr. Vice President of Clinical Research, Dr. Gerald Reaven, has developed a trademarked Syndrome X diet system for persons exhibiting Syndrome X symptoms, and has performed over 20 years of clinical research documenting the benefits of this diet system. Direct comparison clinical trial data supports that this diet system provides superior benefits to those exhibiting Syndrome X symptoms than the low fat/high carbohydrate diet guidelines recommended by the American Heart Association. Approximately 30% of the US population is insulin resistant and subject to Syndrome X. We anticipate that a product line would include bars, drinks, and snacks which follow the trademarked anti-Syndrome X diet system, infused with proprietary Shaman botanicals to address further these metabolic disorders. Many people with AIDS/HIV who are effectively managing the AIDS virus with their antiviral therapies are now also demonstrating metabolic abnormalities consistent with insulin resistance and Syndrome X and are progressing to coronary heart disease and type II diabetes. We intend to leverage the identity we will work to establish in the AIDS/HIV community through our SB-300 product to commence marketing our Syndrome X diet system in this community, and intend to initially target this community. We have identified multiple areas of future dietary supplement product interest and have identified specific priority product candidates. Some of these proposed product areas include gastrointestinal relief, sexual function aids, antioxidants/cardiovascular protectors, sleeping aids, calming agents and weight management. Products in these areas may be developed under the Shaman brand in the future, or selectively out-licensed. Our History Until December 1998, we were solely focused on developing pharmaceuticals 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 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. As a result, we now have available for out-licensing our pipeline of novel pharmaceutical product candidates for major human diseases developed by isolating active compounds from tropical plants with a history of medicinal use. We were incorporated in California in May 1989, began operations in March 1990 and reincorporated in Delaware in January 1993. Our address is 213 East Grand Avenue, South San Francisco, California, 94080-4812 and our telephone number is (650) 952-7070. Our web site is located at http://www.shaman.com.

Summary of the Rights Offering Series R Convertible Preferred Stock offered by Shaman..... 1,000,000 shares at $15.00 per share offered on a pro-rata "rights offering" basis to all owners of shares of our common stock on July 14, 1999. Preferred stock outstanding after the offering.......... Up to 1,016,667 shares of Series R Convertible Preferred Stock 115,958 shares of Series C Convertible Preferred Stock 1,360 shares of Series D Convertible Preferred Stock Common stock outstanding after the offering................ 3,158,233 shares This number is based on shares outstanding as of July 13, 1999 and excludes: * 60,970 shares of common stock subject to outstanding options under our stock option plans; * 104,833 shares reserved for issuance for outstanding warrants; * an estimated 21,513,544 shares reserved for issuance upon the conversion of Series C Convertible Preferred Stock; * an estimated 4,023,127 shares reserved for issuance upon the conversion of Series D Convertible Preferred Stock; and * approximately 163,466,900 shares reserved for issuance upon the conversion of the Series R Preferred Stock being offered hereby and the shares of Series R Preferred Stock that are currently outstanding and are reserved for issuance upon exercise of outstanding warrants, based upon a conversion price of the Series R Preferred Stock of $0.10. Use of proceeds............... We intend to use approximately $600,000 of the funds generated by this rights offering to repay a senior secured lender, and in addition expect to repay up to $1,000,000 borrowed by Shaman to the extent such debt has not been converted into shares of Series R Preferred Stock at the election of the debtholders under a credit agreement entered into in April 1999. The remaining proceeds will be used to fund the initial commercialization of our first product, SB-300, expected to be approximately $2.5 million for initial launch, and to pursue development, production and marketing of our botanicals products, and for working capital, including current liabilities and general purposes. There is no minimum number of shares that we must sell to complete this offering, and the proceeds we receive in this offering could be substantially less than the total of $15 million being offered. 6 Description of Series R Convertible Preferred Stock.. The Series R Preferred Stock will automatically convert into shares of common stock on February 1, 2000. The following is the formula which will be used to calculate the conversion of Series R Preferred Stock: $15 divided by the conversion price equals the number of common stock shares into which each share of Series R Preferred Stock is convertible. The conversion price will be equal to the lower of the following: * $0.10, or * a per share price that is equal to 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. If we sell all of the shares of Series R Preferred Stock in this offering, and if the conversion price of the Series R Preferred Stock is less than $0.10 per share on February 1, 2000, we may not have enough shares of common stock authorized under our certificate of incorporation to effect the conversion of all outstanding shares of Series R Preferred Stock and our other series of preferred stock. If we do not have enough shares of common stock authorized to effect the conversion of the Series R Preferred Stock on February 1, 2000, after taking into account the number of common stock shares necessary to effect the conversion of the then outstanding shares of Series C Preferred Stock and Series D Preferred Stock, only the portion of the Series R Preferred Stock, if any, for which there are adequate common stock shares will be converted, allocated pro rata among the holders of the Series R Preferred Stock. The remaining shares of Series R Preferred Stock will remain outstanding until three trading days after enough common stock shares are authorized to effect the conversion of these shares under our certificate of incorporation. After February 1, 2000, if any shares of Series R Preferred Stock remain outstanding, the conversion price will remain the same as the conversion price in effect on February 1, 2000, subject to adjustments for stock splits, stock dividends and other recapitalizations. The Series R Preferred Stock will be entitled to receive dividends only to the extent that our common stock is entitled to receive dividends and will participate with the common stock pro rata on an as-converted to common stock basis, based on a conversion ratio of 150 shares of common stock for each share of Series R Preferred Stock. In the event of liquidation, dissolution or winding up of Shaman, the holders of the Series R Preferred Stock are entitled to receive, in preference to the holders of the common stock but after payment of the liquidation preferences of any outstanding shares of Series C Preferred Stock and Series D Preferred Stock, an amount equal to $15 per share. Each share of Series R Preferred Stock will have the right to vote on all matters submitted or required to be submitted to the vote of the stockholders and shall have 100 votes per share. Eligible stockholders......... Only persons who owned shares of our common stock on July 14, 1999 will be eligible to purchase shares of Series R Preferred Stock in this offering. 7 Subscription rights........... If you are an eligible stockholder, you will have two subscription rights: (1) Basic subscription privilege. If you held common stock on July 14, 1999, then you will have the right to purchase seven shares of Series R Preferred Stock for each 22.11 shares of common stock you owned as of July 14, 1999. The price of the Series R Preferred Stock is $15.00 per share. We require a minimum subscription of seven shares of Series R Preferred Stock, or $105. This means that if you hold fewer than 22.11 shares of common stock on the record date, you may purchase seven shares of Series R Preferred Stock to meet the minimum subscription requirement, which will constitute your basic subscription privilege. (2) Over-subscription privilege. If you elect to purchase all of the shares that you are eligible to purchase in your basic subscription privilege, you may also request to buy additional shares. In exercising this over-subscription privilege, you must specify the maximum number of shares of Series R Preferred Stock that you are willing to buy at $15.00 per share. We will round up to the nearest whole number in determining the number of shares that we will issue to each stockholder pursuant to these rights. Non-transferabiltiy of subscription rights........... Your basic subscription and over-subscription rights are not transferable. Allocation of shares.......... If we receive subscriptions for more shares than are being offered, we will allocate shares first to those stockholders who are exercising their basic subscription privilege. We will then allocate the remaining shares among those who exercise the over-subscription privilege, in proportion to the maximum number of shares that each subscriber offers to purchase above his basic subscription privilege. Payment for shares............ Payment for shares may be made by delivery of cash, check or money order. How to subscribe.............. You should carefully complete and sign the subscription agreement enclosed with this prospectus and forward it to EquiServe, L.P., our subscription agent, whose address appears below. Be sure to include with your subscription agreement a check or money order for the full amount of your subscription price, including any shares for which you have over-subscribed. Checks and money orders will be cashed and held in escrow by our subscription agent, but will not be distributed to Shaman until we accept your subscription in whole or in part. If your subscription is accepted in part due to over-subscription, the subscription agent will forward to you a check for the difference. No interest will be paid on the funds submitted for subscription. Cancellation of subscription.. Once you have submitted your subscription documents, your exercise of subscription rights may not be revoked. 8 Delivery of subscription Subscription documents should be delivered to the documents................... applicable address below: By Mail ------- EquiServe, L.P. Corporate Actions P.O. Box 9573 Boston, MA 02205-9573 By Hand ------- Securities Transfer & Reporting Services C/O Boston EquiServe 100 Williams Street, Galleria New York, NY 10038 By Overnight Carrier -------------------- EquiSerive, L.P. Attn: Corporate Actions 40 Campanelli Drive Braintree, MA 02184 Persons wishing to exercise for the benefit of others... Brokers, banks, trustees and other individuals or entities that hold common stock for the benefit of others may, if authorized by the beneficial owner, complete the subscription agreement and submit it to the subscription agent with the proper payment. Delivery of certificates for Series R Convertible Preferred Stock............. Certificates representing shares of Series R Preferred Stock will be delivered to subscribers as soon as practicable after your basic subscription has been accepted, which may occur at any time prior to the expiration of this offering. Our acceptance of your basic subscription privilege or any other stockholder's basic subscription privilege is not subject to the receipt of any minimum amount of subscriptions. We may accept your basic subscription amount prior to accepting your over-subscription amount. In that event, we will deliver stock certificates for the basic subscription amount, and the subscription agent will retain the over subscription amount in escrow until the expiration of this offering. At that time, we will determine the amount of the over-subscription to be accepted for each stockholder, and will issue stock certificates and refund any balance due to the stockholders. We expect that this may take two weeks or longer following our acceptance of your subscription, due to the need to allow checks for subscription funds to clear. There is no minimum number of shares we must sell to complete this offering, and we may only be able to sell substantially less of the Series R Preferred Stock than we are offering. Certain federal income tax consequences................ Your receipt or exercise of the subscription rights should not be treated as a taxable event for United States federal income tax purposes, but may have other tax effects. Expiration date of rights offering.................... August 23, 1999, at 5:00 p.m. Eastern Daylight Savings Time, unless extended by Shaman in its sole discretion until September 7, 1999. Termination of offering....... We may cancel this offering at any time. If we cancel the offering, we will return your subscription payment without interest.

You should carefully consider the risks described below and the other information in this prospectus before deciding to invest in shares of our Series R Convertible Preferred Stock. The risks and uncertainties described below may not be the only ones facing Shaman. Additional risks and uncertainties not presently known to us may also impair our business. These risk factors supplement and do not supercede the risk factors contained in our annual report on Form 10-K for the year ended December 31, 1998 and any other filings we make with the Securities and Exchange Commission. If any of the following risks actually occur, our business, operating results and financial condition and your investment in us could be materially and adversely affected. In such case, the trading price of our stock, both common and preferred, could decline and you might lose all or part of your investment. This prospectus also contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of many factors, including the risks faced by us described below and elsewhere in this prospectus. Risks Related to the Rights Offering You will likely experience immediate and substantial dilution in the book value of your investment Assuming that the price at which the Series R Preferred Stock will convert into shares of common stock is $0.10, each share of Series R Preferred Stock will convert into 150 shares of common stock. Since the price of the Series R Preferred Stock is $15.00 per share, this means that the effective per share price of the common stock to be issued upon conversion will be $0.10. Although this price is substantially less than the current market price of our common stock, it is still substantially higher than the net tangible book value of our common stock. In the event that the actual conversion price is equal to this price and we sell a total of 1,000,000 shares of the Series R Preferred Stock in this offering, purchasers of shares of Series R Preferred Stock, on an as-converted into common stock basis, in this offering will experience immediate and substantial dilution of $0.03 in the pro forma net tangible book value per share of common stock. If we sell less than 1,000,000 shares of Series R Preferred Stock, the amount of dilution in the pro forma tangible book value per share of common stock will increase. If the funds raised in this offering do not substantially exceed our offering expenses and current liabilities, we will be unable to fund our operations There is no minimum number of shares we must sell in this offering, and the proceeds could be substantially less than the total of $15 million being offered. If the funds raised in this offering do not cover and substantially exceed our offering expenses and current liablities, and if we are unable to raise funds from an alternative source, we may not be able to continue the commercialization of our first product or fund our operations beyond August 1999. The rights offering will significantly reduce the ownership interest of stockholders who do not participate If you do not exercise your subscription rights, your relative ownership interest in Shaman will be decreased by the issuance of shares of Series R Preferred Stock to those stockholders who exercise their subscription rights. In addition, since the effective price of the common stock into which the Series R Preferred Stock is convertible will be substantially below the market price of the common stock, the issuance of the common stock upon conversion of the Series R Preferred Stock, and subsequent sales of this common stock, will likely depress the market price of the common stock. Any such decrease in the market price of the common stock will in turn also increase the number of shares of common stock into which any shares of Series C and Series D Convertible Preferred Stock that are then outstanding are convertible, causing further reduction in the percentage ownership of the holders of our common stock, particularly to those stockholders who do not participate. The Series R Preferred Stock could trade substantially below the initial offering price We have obtained an opinion from Alliant Partners that the terms of the rights offering are fair, from a financial point of view, to our stockholders. Nevertheless, the offering price does not necessarily bear any relationship to the book value of our assets, past operations, cash flow, earnings, financial condition or any other established criteria for value and should not be considered an indication of our underlying value. Our common stock and the Series R Preferred Stock may trade at prices below the offering price at any time after the date of this prospectus. This offering is not being managed by any underwriter or market maker. As a result, the price of the Series R Preferred Stock may be subject to fluctuation and variability and may trade substantially below the initial offering price. 12 You will not be able to cancel your subscription prior to the expiration date of the offering and will be unable to sell your shares until stock certificates are issued to you, even if the trading price of the Series R Preferred Stock declines before you are able to sell it Since we may accept basic subscription privileges and may issue shares of Series R Preferred Stock prior to the expiration of this offering, the Series R Preferred Stock may begin trading before the expiration of the offering. The public trading market price of the Series R Preferred Stock may decline before the subscription rights expire. Once you have exercised your subscription rights, you may not revoke your exercise for any reason. Until certificates are delivered upon acceptance of your subscription, you will not be able to sell the shares of Series R Preferred Stock that you purchase in the rights offering. Delivery of these certificates is subject to delay. We will not pay you interest on funds delivered to the subscription agent pursuant to the exercise of your subscription rights. We may terminate the rights offering at any time. If we elect to withdraw or terminate the rights offering, neither we nor the subscription agent will have any obligation with respect to the subscription rights except to return, without interest, any subscription payments. If we lose the right to use our net operating losses as a result of a change in control resulting from this offering, we could be subject to greater tax liabilities in the future, which could adversely affect our future operating results and cash flows and thereby could decrease our stock price The completion of the rights offering may result in a "change of ownership" under the provisions of the Internal Revenue Code of 1986 and similar state code provisions. Utilization of our net operating losses and credits may be subject to a substantial annual limitation due to these "change in ownership" provisions. The annual limitation may result in the expiration of net operating losses and credits before utilization, which could subject us to greater tax liabilities in future periods and adversely affect our operating results and cash flows, which could decrease our stock trading price. We expect to record a significant deemed dividend in connection with the issuance of the Series R Preferred Stock, which will increase our net loss applicable to common stockholders and could decrease our stock price The conversion price at which the Series R Preferred Stock is convertible into shares of our common stock will be discounted from the reported trading price by 90%. For financial accounting purposes, a portion of the proceeds of this offering will be allocated to this "beneficial conversion" feature and recognized as a deemed dividend to our preferred stockholders over the period from the date the shares are issued to February 1, 2000. This deemed dividend will increase the net loss applicable to our common stockholders. We will be unable to determine the exact amount of the dividend to be recognized until the date the Series R Preferred Stock is issued, however, based on the current market price of our common stock and assuming a conversion price of $0.10, substantially all of the proceeds will be allocated to the deemed dividend. The increase in the net loss applicable to common stockholders resulting from the deemed dividend could decrease our stock price. If we do not have on February 1, 2000, an adequate number of common stock shares authorized to effect the conversion of all of the preferred stock, all or a portion of the Series R Preferred Stock may remain outstanding indefinitely or until an adequate number of common stock shares are authorized, which could adversely affect the liquidity and price of the Series R Preferred Stock Since we can not know the conversion price of the Series R Preferred Stock until February 1, 2000, we can not currently determine how many shares of common stock we will need to issue upon conversion of the Series R Preferred Stock. Our certificate of incorporation provides that the Series R Preferred Stock will convert on February 1, 2000 only to the extent that we have enough common stock shares authorized to issue all shares of common stock needed to effect the conversion of all outstanding shares of our Series R Preferred Stock, after taking into account the number of common stock shares necessary to effect the conversion of any then outstanding shares of Series C Preferred Stock and Series D Preferred Stock. In the event that we do not have enough shares authorized, only the portion of the Series R Preferred Stock for which we have authorized shares of common stock will be converted, on a pro rata basis among the holders of the Series R Preferred Stock. The remaining shares will remain outstanding until we have amended our certificate of incorporation to authorize an adequate number of common stock shares. If we sell all of the shares of Series R Preferred Stock in this offering and if the conversion price of the Series R Preferred Stock is less than $0.10 per share on February 1, 2000 we will need to authorized additional shares of common stock to effect the conversion of all shares of our outstanding preferred stock, which will require stockholder approval. If it appears likely that we will need to authorize more shares of common stock, we anticipate submitting to our stockholders, prior to the conversion date of the Series R Preferred Stock, a proposal to increase the number of shares of common stock we are authorized to issue to a number we believe will be adequate to effect the conversion of all of our preferred stock, including the Series R Preferred Stock. If the stockholders do not approve such an increase in the authorized common stock, all or a portion of the Series R Preferred Stock may not convert on February 1, 2000 and may remain outstanding indefinately after February 1, 2000 until we can amend our certificate of 13 incorporation to authorize additional shares of common stock to effect this conversion. The delay in conversion of or the indefinite inability to convert all or a portion of the Series R Preferred Stock may decrease the liquidity and the market price of the Series R Preferred Stock. Risks Associated with our Business If we do not raise significant additional capital, we will be unable to commercialize our first product or to fund continuing operations, and may be forced to cease 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. Our projections show that cash on hand plus approximately $1.0 million we have borrowed under a credit agreement entered into in April 1999 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 this 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 therefore 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. 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. 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, especially those who do not participate in this proposed rights offering, 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. If we are unable to continue as a going concern, investors will lose their investment 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. If we are to remain as a going concern, we will need to become and remain profitable and may also need financing in addition to the funds raised in this offering. We may not be successful in achieving profitability or in obtaining new financing and may have to curtail or cease operations, which could cause our stockholders, including purchasers of the Series R Preferred Stock, to lose their investment. 14 We have a history of operating losses, expect continuing losses and may never achieve profitability We have incurred significant losses in each year since our founding in 1989 and expect to continue to incur 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, and 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 or 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 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 addition, there are currently outstanding 16,667 shares of Series R Preferred Stock and warrants to purchase 73,112 shares of Series R Preferred Stock. The exercise of these warrants and the sale of common stock underlying the Series R Preferred Stock will also dilute the common stock. If we are not successful in transitioning into the botanical dietary supplements business, we may never achieve revenues or profitability We have transitioned 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 and may never generate revenues or profitability from our botanicals business. 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. If third party manufacturers on whom we rely fail to perform their services, our supply of products would be delayed and possibly disrupted 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 15 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. Since we have only a limited marketing staff, we may never achieve adequate sales and revenues to achieve profitability We currently have minimal marketing staff. If we are unable to successfully establish, execute and finance a complete marketing plan for our first product, SB-300, or subsequent products, we may not achieve a successful product entry into the marketplace and may fail to achieve adequate sales and revenues from our botanical products to achieve profitability. It is unlikely we would ever achieve profitability if our first product is not successfully marketed and sold. We may incur material 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 us 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. If we fail to compete in the intensely competitive botanical dietary supplement industry, we may never achieve profitability The dietary supplement business is highly competitive and is characterized by significant pressure on pricing and heavy commitment of marketing resources for commodity products. Although our products are proprietary, we may face competition from start-up companies developing and marketing new commercial products that have or claim to have similar functionality. Our failure to successfully compete for customers would inhibit our future growth, revenues and profitability. 16 If we do not succeed in marketing our botanical products over the Internet, we may be unable to sell adequate volumes of our products or generate revenues adequate to achieve profitability 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 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, and if we do not succeed, we may be unable to generate adequate revenues to achieve profitability. Since our business plan relies substantially on marketing our future products over the Internet, if our third party Internet access providers fail to keep our web site operational, sales of our products would be disrupted and our marketing efforts would be harmed. We intend to market our first product primarily over the Internet, and will rely 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 would disrupt sales and discourage use of our web site by customers, which would have a material adverse effect on our revenues and profits. On-line security breaches of our web site could harm our business by substantially increasing our costs, exposing us to liability and harming our sales and marketing efforts 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. 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 measures may not be sufficient to prevent security breaches, and the failure to prevent such security breaches could increase our costs, disrupt our sales and marketing efforts and result in costly liability to Shaman. Government regulation of dietary supplements could increase our costs or prohibit or limit sales of our products 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, defined as 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 17 "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. The costs of compliance with environmental laws and regulations, or our inability or failure to comply with environmental laws and regulations, could substantially increase our costs of doing business or result in liability that could use substantial amounts of our cash resources 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 require us to use a large amount of cash, which would then not be available for funding operations or development and commercialization of our products. Product liability claims asserted against us in the future could exceed our insurance coverage and result in substantial liability to Shaman 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 be required to use a large amount of cash, which would then not be available for funding operations or development and commercialization of our products. Since the dietary supplement industry is particularly susceptable to public perception of its products, negative publicity regarding the safety or quality of our products could adversely impact our sales of these products 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 sales and our ability to market our products 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 18 our products or any similar products distributed by other companies could affect the market acceptance of our products, decrease sales, and make it more difficult to market and sell our products. 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 decrease sales and make it more difficult to market and sell our products. Our dependence on raw plant material from Latin and South America, Africa and Southeast 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 disrupt or delay sales of our products, inhibit our ability to market our products, and 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 disrupt supplies, cause the cost of supplies to increase dramatically, and materially and adversely affect our business, financial condition and results of operations. If we fail to protect our intellectual property rights, we could lose our ability to stop competitors from using our trademarks or selling our products 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 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 us 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 19 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 us 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. If a third party were to bring an infringement claim against us, we would need to expend significant resources in our defense; if the claim were successful, we would need to obtain licenses or develop non-infringing technology 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. If any of our executive officers and key personnel leave Shaman, our ability to launch our first product or to market our products, and our ability to develop any new products, could be delayed or disrupted; we could also need to expend significant resources to hire new personnel 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 delay and inhibit our ability to launch and market our products, develop new products, or effectively manage our business. 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. 20 "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. Accredited investors generally include investors that 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% of the outstanding shares are required to call a special meeting of stockholders. Our board will also have the authority to issue up to 93,715 additional shares of preferred stock, after giving effect to the issuance of up to 1,300,000 shares of Series R Preferred Stock, and to fix the price, rights, 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. 21 WHERE YOU CAN FIND MORE INFORMATION This prospectus is part of a registration statement on Form S-1, File No. 333-78115, we have filed with the Securities and Exchange Commission.

We intend to use the funds generated by this offering to retire certain existing debt, pursue development, production and marketing of products within the botanicals business and for working capital purposes. We intend to use approximately $600,000 of the net proceeds of this offering to repay indebtedness to GATX/MMC Partnership No. 1, and up to $1,000,000 of indebtedness to certain stockholders, officers, and directors of Shaman under a credit agreement entered into in April 1999, unless such debt is converted at the election of the holders of this debt into Series R Preferred Stock. We expect to use the balance of the net proceeds for the initial commercialization of our first product, SB-300, currently budgeted at approximately $2.5 million, and for the development, production, and marketing of our other botanical product candidates, for working capital, including current liabilities and for general corporate purposes. In the event that less than all of the shares of Series R Preferred Stock are sold, we will still be required to repay approximately $600,000 in outstanding indebtedness. To the extent less than all of the shares of Series R Preferred stock are sold, we will have fewer funds available for the commercialization of SB-300 and for the funding of our operations. The amounts actually expended for these purposes may vary significantly depending upon numerous factors, including the amount raised by this offering, progress of our research and development programs, the status of competitive products and the availability of alternative financing, including agreements with other companies relating to the development and marketing of our products and the other factors described under "Risk Factors." Accordingly, we will retain broad discretion in the allocation of the net proceeds of this offering. Pending such uses, the net proceeds of this offering will be invested in United States government securities, other investment grade debt securities and other short-term investments. See "Management's Discussion and Analysis of Financial Condition and Results of Operations -- Liquidity and Capital Resources." 23 PRICE RANGE OF COMMON STOCK Since February 2, 1999, Shaman's common stock has been traded on the OTC Bulletin Board of the National Association of Securities Dealers, Inc. under the symbol "SHMN." Our common stock was traded on the Nasdaq Stock Market from our initial public offering on January 26, 1993 until February 1, 1999. Set forth below is the range of high and low closing sale prices for Shaman's common stock for the periods indicated, as reported by the OTC Bulletin Board or The Nasdaq Stock Market, as applicable, and as adjusted for the 1-for-20 reverse stock split effected on June 22, 1999: High Low ------ ----- Fiscal Year 1997 First Quarter Ended March 31, 1997 $ 125.00 $ 77.60 Second Quarter Ended June 30, 1997 $ 123.80 $ 93.80 Third Quarter Ended September 30, 1997 $ 140.00 $ 102.40 Fourth Quarter Ended December 31, 1997 $ 141.20 $ 85.00 Fiscal Year 1998 First Quarter Ended March 31, 1998 $ 110.00 $ 82.60 Second Quarter Ended June 30, 1998 $ 100.00 $ 88.20 Third Quarter Ended September 30, 1998 $ 80.00 $ 63.80 Fourth Quarter Ending December 31, 1998 $ 66.20 $ 21.80 Fiscal Year 1999 First Quarter Ended March 31, 1999 $ 40.60 $ 3.40 Second Quarter Ended June 30, 1999 $ 4.69 $ 0.72 Third Quarter Ended September 30, 1999 (through July 13, 1999) $ 0.63 $ 0.53 DIVIDEND POLICY We have paid no cash dividends on the common stock since our inception and do not anticipate paying any dividends in the foreseeable future. Our loan agreement with MMC/GATX Partnership No. 1 restricts the payment of cash dividends on any equity security so long as any amount remains outstanding under such loan agreement. In addition, Shaman's charter requires that Shaman pay all required dividends to the holders of Series C Preferred Stock and Series D Preferred Stock, respectively, prior to the payment of dividends to the holders of our common stock or Series R Convertible Preferred Stock. At March 31, 1999, we had an accumulated deficit of $159.0 million and, until this deficit is eliminated, we will be prohibited from paying cash dividends except out of net profits. 24 CAPITALIZATION The following table sets forth the unaudited actual capitalization of Shaman as of March 31, 1999 and as adjusted to reflect the sale of 1,000,000 shares of Series R Preferred Stock offered hereby at the estimated public offering price of $15.00 per share and after deducting the estimated offering expenses of $300,000.

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 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, 1998 and 1999 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. Restructuring Costs 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, which was then 65% of our 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 Shaman's restructuring activities as of March 31, 1999. Total Restructuring Balance Category Charges Spending 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 ======== ======== ======== We recorded collaborative revenues of $875,000 and $0 for the quarters ended March 31, 1998 and 1999, 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 and research funding from our collaboration with Ono Pharmaceutical Co. Ltd. of Osaka, Japan, which expired in May 1998. 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. 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 27 with Lipha/Merck for the discontinuation of this agreement. There will be no further research payments from Lipha/Merck. See "Risk Factors Costs incurred in connection with the termination of prior research and development agreement could adversely impact our business". We incurred research and development expenses of $7.5 million and $2.5 million, of which $149,000, was related to the research and development of the botanicals division for the quarters ended March 31, 1998 and 1999, 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 compared to 1998 annual and quarter ended March 31, 1998 as we focus our efforts in our botanicals business, effective February 1, 1999. General and administrative expenses were $1.3 million and $1.5 million for the quarters ended March 31, 1998 and 1999, 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 $232,000 and $73,000 for the quarters ended March 31, 1998 and 1999, 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 $807,000 and $259,000 for the quarters ended March 31, 1998 and 1999, 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. Results of Operations for the Years Ended December 31, 1996, 1997 and 1998 The results of operations for the years ended December 31, 1996, 1997 and 1998 were for our pharmaceutical operations. Our results of operations for fiscal year 1999 will not be comparable, as we ceased operations of our pharmaceutical business and focused our efforts in our botanical business in first quarter of 1999. We recorded collaborative revenues of $3.4 million, $3.5 million and $2.7 million for 1996, 1997, and 1998, respectively. Revenues for 1998 resulted from research funding from our collaboration with Lipha/Merck and research funding from our collaboration with Ono Pharmaceutical Co. Ltd., which expired in May 1998. Revenues for 1997 also resulted from research funding from our collaboration with Lipha/Merck and Ono. Revenues for 1996 resulted from research funding from our collaboration with Ono, an additional $1.0 million payment from Ono for enhanced rights to our antidiabetic compounds, and research payments and access fees from our collaboration with Lipha/Merck. We incurred research and development expenses of $19.1 million, $24.1 million, and $32.4 million for 1996, 1997 and 1998, respectively. These expenses include salaries for scientific personnel, clinical development costs, laboratory supplies, patent protection and consulting fees, travel, plant collections, facilities expenses and other expenditures relating to research and product development. Research and development expenses increased $5.0 million in 1997 compared with 1996, and $8.3 million in 1998 compared with 1997. The increase in 1997 was primarily attributable to an increase in clinical development activities with respect to SP-303/Provir of $3.8 million and to increased scientific salaries of $1.2 million, which were partially offset by reduced expenses for clinical development activities for nikkomycin Z of $1.1 million. The increases in 1998 were primarily attributable to the completion of a $7.0 million Phase III human clinical trial for SP-303/Provir for the treatment of diarrhea in people with AIDS and $2.4 million of the manufacturing scale-up and to increased scientific salaries of $1.2 million, which were partially offset by a reduction of costs associated with our diabetes program of $2.8 million. Research and development expenses are expected to decrease in 1999 as we ceased operations in our pharmaceutical business and focused our efforts in our botanicals business, effective February 1, 1999. General and administrative expenses were $3.5 million, $4.8 million and $5.6 million for 1996, 1997 and 1998, respectively. These expenses include administrative salaries, consulting, legal, travel and other operating expenses. General and administrative expenses increased $1.3 million in 1997 compared to 1996, and increased $0.7 million in 1998 compared to 1997. The increase in 1997 was primarily attributable to an increase in compensation and marketing research of $388,000 related to development of SP-303/Provir, as well as additional legal expenses of $631,000 primarily related to certain disputes related to our intellectual property rights. The increase in 1998 over 1997 was primarily attributable to additional costs, including an increase in compensation, consulting expenses and commercial development activities of $530,000, related to the development of SP-303/Provir. General and administrative expenses are expected to decrease in 1999 as we ceased operations in our pharmaceutical business and focused our efforts in our botanicals business, effective February 1, 1999. Interest income was $1.1 million, $1.2 million and $0.6 million for 1996, 1997 and 1998, respectively. Interest income increased $100,000 in 1997 compared with 1996, and decreased $700,000 in 1998 compared with 1997. Interest income fluctuations have been consistent with changes in average cash and investment balances with which we substantially funded our operations in 1996, 1997 and 28 1998. The balances of cash, cash equivalents and investments were $16.5 million, $21.4 million and $9.2 million at December 31, 1996, 1997 and 1998, respectively. Interest expense was $603,000, $5.0 million and $2.0 million for 1996, 1997 and 1998, respectively. Interest expense increased in 1997 compared with 1996 principally due to a $3.7 million non-cash interest charge related to the issuance of senior convertible notes in June 1997, as well as the interest expense related to our secured debt financing in May 1997. Interest expense decreased in 1998 compared with 1997 principally due to a $3.7 million non-cash interest charge related to the issuance of senior convertible notes in June 1997, offset by interest expense related to capital lease agreements and the secured debt financing. Interest expense in the future will be dependent in part on our capacity to finance future operating and equipment needs. 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. At December 31, 1998, we had federal net operating loss carryforwards of approximately $48.6 million. The federal net operating loss carryforwards will expire at various dates beginning in 2004 through 2013, if not sooner utilized. Utilization of the net operating losses and credits is subject to a substantial annual limitation due to the "change in ownership" provisions of the Internal Revenue Code of 1986, as amended. The annual limitation may result in the expiration of net operating losses and credits before utilization. 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. 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, pursuant to which we may borrow up to 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. Any convertible promissory notes issued pursuant to the credit agreement will be due and payable on the earlier of (1) 30 days subsequent to the completion of the public offering, or (2) December 31, 1999. Interest on the convertible promissory notes will accrue at an annual rate of 12%. The convertible promissory notes, if and 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. The delisting of our common stock from The Nasdaq National Market constituted an Optional Redemption Event, as defined in our Certificate of Incorporation, for the Series D Preferred Stock. In connection therewith, on February 4, 1999, we issued a Control Notice, as defined in the Certificate of Incorporation, that prevented the redemption of the Series D Preferred Stock. This Control Notice will remain in effect for as long as we are not listed on any of The Nasdaq National Market, The Nasdaq SmallCap Market, the American Stock Exchange or the New York Stock Exchange. Delivery of the Control Notice 29 had the effect of increasing the annual dividend to $180 per share and adjusting the conversion price of the Series D Preferred Stock to 72% of the low trading price during a designated time period prior to the conversion. In December 1998, we completed a private sale of 240,604 shares of common stock for aggregate net proceeds of approximately $7.1 million. In connection with this offering, we have committed a five-year, 3.6% royalty on net sales of SP-303/Provir, if any, in the United States for distribution to HIV/AIDS charities. We intend to honor this royalty payment through the sale of our first botanical product, SB-300, to be initially marketed to the HIV/AIDS community. In December 1998, we issued 37,360 shares of common stock to consultants for services rendered. We recorded an expense of approximately $1.1 million in conjunction with the consulting services. In October 1998, we completed the sale to the public of an aggregate of 140,880 shares of our Series C Convertible Preferred Stock for aggregate gross proceeds of $14.1 million. Each share of Series C Preferred Stock is entitled to receive cumulative dividends paid semi-annually to the holders of record of such shares as follows: (1) an annual stock-on-stock dividend, paid in arrears, in shares of common stock, calculated as the quotient of $10.00 divided by 85% of the average closing price of the common stock for the 10-day trading period ending three trading days prior to the date the dividend is paid; plus (2) a cash amount equaling 0.00005% of our U.S. net sales of our SP-303/Provir product for the treatment of diarrhea, if any, for the preceding two calendar quarters less $5.00. If, under Delaware law, we are unable to pay the cash portion of the dividends, then the cash portion will be paid in shares of common stock valued at 85% of the average closing price of the common stock for the 10-day trading period ending three trading days prior to the date on which the dividend is paid. We intend to honor this royalty portion of the dividend through the sale of our first botanical product, SB-300, to be initially marketed to the HIV/AIDS community. Each share of the Series C Preferred Stock was convertible for a period of 30 days after August 18, 1998, and will be convertible again commencing 12 months after the initial issuance date at the election of each holder, and automatically on the sixth anniversary of the initial issuance date into the greater of (1) 0.8333 shares of common stock or (2) such number of shares of common stock as equals $100, which was the price paid per share of Series C Preferred Stock, divided by 85% of the average closing price of the common stock reported by Nasdaq for the 10-day trading period ending three trading days prior to the date of conversion. The common stock is currently trading on the OTC Bulletin Board. During the initial 30-day conversion period for the Series C Preferred Stock, 24,922 shares of the Series C Preferred Stock were converted into an aggregate of 93,077 shares of common stock. In connection with the issuance of the Series C Preferred Stock, we recognized a non-cash charge in the amount of $679,000. In June 1998, we entered into stock purchase agreements with certain of our stockholders pursuant to which we acquired the right to sell to these stockholders, subject to certain conditions up to an aggregate of 7,000 shares of Series B Custom Convertible Preferred Stock for an aggregate purchase price of $7,000,000. The stock purchase agreements were terminated upon the closing of the Series C Convertible Preferred Stock financing in October 1998. As consideration for entering into the stock purchase agreements, we issued to these stockholders warrants to purchase an aggregate of 17,500 shares of common stock. The warrants are exercisable for a period of five years at an exercise price per share equal to 115% of the average trading price of the common stock during specified measurement periods. We have attributed a value of $1.5 million to these warrants. In June 1997, we issued $10.4 million of senior convertible notes. The notes mature in August 2000 and bear interest at a rate of 5.5% per annum. Interest on the notes was payable in common stock or cash at our option. Initially, the notes were convertible into common stock at 100% of the low trading price during a designated time period prior to conversion provided that the conversion price would not be less than $110.00 per share. Starting in November 1997, the notes were convertible into common stock at a 10% discount from the low trading price during a designated time period prior to the conversion, with a floor of $110.00 through March 31, 1998, pursuant to a November 1997 understanding with the note holders to revise the terms of the notes (see next paragraph). Of the notes issued, $400,000 was issued to the placement agent as part of the placement fee. We paid the placement agent an additional $300,000 in cash. The placement fees and other offering costs were capitalized in other assets as deferred issuance costs and were amortized to interest expense over the life of the notes to the extent the notes were not converted to common stock. The net proceeds totaled approximately $9.5 million after the placement agent's fees and other offering expenses. In March 1998, Shaman and the purchasers of the notes entered into an amendment agreement with the purchasers of the notes in order to avoid conversion of the notes at a price that would be unduly dilutive to our existing stockholders. As consideration for entering into the amendment agreement, we issued to the purchasers of the notes warrants to purchase an aggregate of 6,875 shares of common stock. The warrants are exercisable through March 18, 2001 at an exercise price of $150.00 per share. We have attributed a value of $309,000 to these warrants. On December 10, 1998, we issued to the note holders an aggregate of 4,784 shares of the Series D Convertible Preferred Stock in exchange for the cancellation of an aggregate of $4.8 million, including accrued interest, of the notes. Each share of Series D Convertible Preferred Stock is entitled to receive, when, as, and if declared by the Board of Directors out of funds legally available for such purpose, cumulative dividends at the rate of 30 $55 per annum. Dividends on the Series D Preferred Stock are payable in cash or shares of common stock or any combination of cash and shares of common stock, at our option and are payable quarterly on February 1, May 1, August 1 and November 1 of each year. Each share of Series D Preferred Stock is convertible, at any time, into the common stock at the lesser of (1) $22.50 per share or (2) 90% of the low trading price during a designated time period prior to the conversion. In addition, the holders received an aggregate of 38,373 warrants to purchase additional shares of common stock in exchange for surrendering the redemption rights previously held by them under the notes. The warrants were priced at 150% of the average closing price for the month of December 1998. We have attributed a value of $943,680 to these warrants. In May 1997, we obtained a $5.0 million, 36-month term loan to pay off pre-existing debt, finance capital asset acquisitions and finance continued research and clinical development of our product candidates. The loan carries an interest rate of 14.58% and is payable in equal monthly installments over the term of the loan. The lender was granted ten-year warrants to purchase 10,000 shares of common stock at $125.00 per share. We have attributed a value of $648,000 to these warrants. In April 1997, we sold 80,000 shares of common stock at $99.40 per share in a registered direct public offering, which yielded gross proceeds of $7.95 million. The net proceeds of approximately $7.8 million from this offering were used for the continued research and clinical development of our product candidates. In January 1997, we sold 100,000 shares of common stock in a registered direct public offering for gross proceeds of $9.0 million. The net proceeds of approximately $8.1 million from this offering were used for the continued research and clinical development of our product candidates. In September 1996, we entered into a five-year collaborative agreement with Lipha/Merck to jointly develop our antihyperglycemic drugs. Upon signing the collaboration, we received an annual research fee of $1.5 million which was amortized to revenue over twelve months, as work was performed. We also received approximately $3.0 million for 19,446 shares of common stock priced at $154.20 per share, representing a 20% premium to the weighted average price of the common stock at the time of purchase. In exchange for development and marketing rights in all countries except Japan, South Korea, and Taiwan, which countries are covered under an earlier agreement between Shaman and Ono, Lipha/Merck agreed to provide up to $9.0 million in research payments and up to $10.5 million in equity investments priced at a 20% premium to a multi-day volume weighted average price of the common stock at the time of purchase. The agreement also provided for additional preclinical and clinical milestone payments to us in excess of $10.0 million per compound for each antihyperglycemic drug developed and commercialized. Lipha/Merck agreed to bear all pre-clinical, clinical, regulatory and other development expenses associated with the compounds selected under the agreement. In addition, as products are commercialized, we would receive royalties on all product sales outside the United States and up to 50% of the profits, if we exercised our co-promotion rights, or royalties on all product sales in the United States. Certain of the milestone payments would be credited against future royalty payments, if any, due to us from sales of products developed pursuant to the agreement. 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. For the year ended December 31, 1998, we recognized $1.9 million in revenue from the Lipha/Merck collaboration. In addition, we received a total $2.5 million for issuance of 57,762 shares of common stock, of which 40,650 shares were priced at $37.00 per share in September 1998 and 17,112 shares were priced at $58.40 per share in December 1998, each representing a 20% premium to the weighted average price of the common stock at the time of purchase. On February 1, 1999, we discontinued all the research and development activities related to the collaborative agreement. We are currently in negotiations with Lipha/Merck for the discontinuation of this research agreement. There will be no further research payments from Lipha/Merck. In July 1996, we closed a private placement pursuant to Regulation S under the Securities Act of 1933, as amended, in which we received gross proceeds of $3.3 million for the sale of 400,000 shares of Series A Convertible Preferred Stock and for the issuance of a six-year warrant to purchase 27,500 shares of common stock at an exercise price of $203.60 per share. The Preferred Stock does not carry a dividend obligation and will convert into common stock no later than July 23, 1999 at a price per share between $120.00 and $163.00, depending on the market value of common stock during the period prior to conversion. The holder of preferred shares is entitled to a liquidation preference of $163.00 per share. 31 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. Our cash, cash equivalents and investment balances are approximately $2.7 million at March 31, 1999. We anticipate that our cash, cash equivalents and investment balances, and the net proceeds from this offering, assuming all of the shares are sold in the offering, will be adequate to fund our operations through at least the end of 1999. Our projections show that cash on hand plus approximately $1.0 million available under the Credit Agreement 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 this 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 therefore be unable to fund the operations of our botanicals business, 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 the operations of our botanicals business on a long-term basis. If additional funds are raised by issuing equity securities, significant dilution to existing stockholders may result and there can be no assurance that additional funding will be available on reasonable terms, or at all. 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 performed by our employees, and we have therefore not incurred any external costs. We estimate that upgrades for those systems not in compliance will total approximately $280,000. 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 in the process of asking our significant suppliers and subcontractors that do not share information systems with us whether their systems are year 2000 compliant. To date, we are not aware of any suppliers or subcontractors 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 suppliers or subcontractors will be year 2000 ready. The inability of our suppliers or subcontractors to complete their year 2000 resolutions to process in a timely fashion could materially and adversely 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 1999 and determine whether such a plan is necessary. 32 Qualitative and Quantitative Disclosures About Market Risk We are exposed to market risk, including changes to interest rates. A discussion of our accounting policies for financial instruments and further disclosures relating to financial instruments is included in the Summary of Significant Accounting Policies in the Notes to Financial Statements. We monitor the risks associated with interest rates and foreign currency exchange risks and have established policies and business practices to protect against these and other exposures. We place our investments in instruments that meet high credit quality standards, as specified in our investment policy guidelines; the policy also limits the amount of credit exposure to any one issue, issuer, or type of instrument and does not permit derivative financial instruments in our investment portfolio. As a result, we do not expect any material loss with respect to our investment portfolio. The following table provides information about our financial instruments that are sensitive to changes in interest rates. For investment securities, the table presents principal cash flows and related weighted-average interest rates by expected maturity dates.

Our actual results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including the risks faced by us described below and elsewhere in this prospectus. Overview We are focused on the discovery, development, and marketing of novel, proprietary botanical dietary supplements derived from tropical plant sources. We intend to implement our commercialization efforts through our recently established botanicals division, which we have named ShamanBotanicals.com. Our commercialization plan includes the use of community building initiatives on the Internet and other distribution channels, and is based on marketing our exclusive access to our proprietary branded products. We also have available for out-licensing a pipeline of botanical product candidates, as well as novel pharmaceutical product candidates for major human diseases developed by isolating active compounds from tropical plants with a history of medicinal use. Botanicals Background In 1997, the U.S. dietary supplement market was $12.9 billion. Of this, over $4.0 billion were herbal or botanical dietary supplements. In 1998, this number was projected to reach $5.0 billion, with a compounded yearly growth rate of approximately 35%. In 1997, 24% of U.S. households reported using herbal or botanical dietary supplements. The growth of this market has been led by consumers who are interested in complementary, non-pharmaceutical options for treating symptoms, fulfilling unmet dietary needs, and optimizing health, either as an alternative to, or in conjunction with, more conventional medical approaches. We believe that the use of these products will continue to expand based upon the aging of the population, increasing scientific evidence and acceptance by the conventional medical establishment, and the recent entrance of powerful consumer companies which provide greater product confidence, while growing the base of consumer users. We believe that room exists for significant continuing growth of the dietary supplement market and expect the two key drivers of market growth to be (1) growth in the number and breadth of consumers utilizing these products; and (2) continuing effective product innovation to fuel both trial and repurchase. Growth in the number and breadth of consumers utilizing these products has already begun, and is based in part upon the entrance of the large consumer healthcare companies into the botanical dietary supplements market. These companies have increased the visibility of botanical dietary supplements, placing them not only in local health food stores but also in neighborhood grocery stores, drug stores, and mass merchandisers. Additionally, these companies are spending on large direct-to-consumer advertising campaigns, placing advertisements during primetime television and in mainstream newspapers and magazines. Consumer surveys show this advertising has resulted in a broader base of consumers being made aware of, trying and utilizing dietary supplements. Simultaneous with the broadening of the consumer base, the botanical dietary supplements market has grown partially as a result of the media highlighting new products. For example, in 1997, ABC's 20/20, The New York Times and Newsweek carried a series of stories about St. John's wort, increasing trial and usage of this dietary supplement dramatically. Interestingly, while the month-on-month growth of sales of St. John's wort has now slowed, this initial increase in sales has been maintained throughout the industry. These new product "bursts" have fueled episodic but sustained market growth by driving new purchases, and in the process, the repurchase of other products once the consumer is at the point of purchase. Hence, the industry's view is that the media and consumers are looking for continuing effective product innovation--for the next St. John's wort--to fuel both trial and repurchase. Products with a proprietary position have proven to be particularly successful in the past. Finally, as more consumers have entered the dietary supplement market, they have also begun to demand better quality, more consistency and standardization of products, and scientific evidence regarding the safety and efficacy of products. Increased demand has also strained the supply of natural plant material for some popular products. Not all companies in the industry have proven capable of meeting these consumer demands. 34 Strategy The concept for our ShamanBotanicals.com division was developed in 1998, and has become the focus of our operations in 1999. The purpose of the botanicals business is to discover, develop and market novel, proprietary botanical dietary supplements derived from tropical plant sources through community building initiatives on the Internet and other focused marketing channels. The unique positioning of our botanicals business stems from our prior experience and efforts in developing pharmaceutical products from tropical plant sources, including significant financial investment, more than 10 years of extensive field research by our teams of ethnobotanists and physicians, and pharmaceutical-level chemical standardization, biological and clinical testing. We are applying this methodology to our new industry, and we intend to set a new standard in this industry. In the last decade, we have amassed a large body of information on the health benefits of thousands of tropical plant species that have a history of human use, and we have organized this information into an extensive relational database. This database includes over 2,600 tropical plants, many of which have not been introduced or fully developed in the U.S. dietary supplement market. We have identified plants with a documented ethnomedical history of use in our library and database of botanicals for use in key market categories with significant commercial potential. Because many of these plants reflect the previously untapped plant diversity of the rainforests, they may represent novel botanical products that have the opportunity to attain a strong, proprietary market position. We currently have a fully-developed product, SB-300, and we expect to commercialize this product in the near future by applying the funds raised in this rights offering and via partnering development agreements we are working to put in place. We have the opportunity to differentiate our product candidates in consumers' minds relative to those of our competitors. Key points of differentiation include: * Novel plants/proprietary products for unmet needs; * Documented, first-hand field experience with traditional use; * Rainforest-based plants and products, since most botanical supplements products currently come from plants found in temperate areas; * Our commitment to conservation and reciprocity; * Sustainable sourcing and supply; * Quality manufactured, standardized products; and * Clinically-tested products. Our commercialization strategy is to create high-end branding of the Shaman name, on our propriety products addressing serious unmet healthcare concerns, and to market these proprietary products to specific communities affected by such healthcare issues. Our e-commerce web site, ShamanBotanicals.com, which is currently under construction, will be designed to include several distinct features, such as exclusive access to our proprietary products, and links to peer-reviewed clinical data supporting the clinical action of our products. We also intend to offer access to certain medical experts, in some cases exclusively, for medical commentary. Other planned features of our web site include bulletin board postings, community chat rooms, customer security and customization, and affiliate programs. Finally, information on our reciprocity programs will be available as well. Product Discovery and Development Process We build on the knowledge and expertise of ethnobotanist and physician teams who work with traditional healers to identify effective treatments in the therapeutic areas that we have targeted. These teams gather comparative data on traditional medicinal and health uses of plants from geographically diverse tropical areas and prioritize plant candidates based on common use among cultures and other factors. The prioritization process includes cross-checking field-derived information against the results of literature searches as to chemical constituents, previously discovered biological activity and other reported medicinal uses. This process is integral to both our pharmaceutical and dietary supplement discovery and development programs. We were able to initiate our botanicals business by further exploring the botanical library and pipeline we have developed over the past 10 years. In the last decade, we have amassed a large body of information on the healing benefits of thousands of tropical plant species that have a history of human use and have organized this information into an extensive relational database. This database includes information on over 2,600 tropical plants, many of which have not been introduced or fully developed in the U.S. dietary supplement market. Currently, most dietary supplements are derived from plants from temperate regions. We have identified plants with a documented ethnomedical history of use in our library and database of botanicals for use in key market categories with significant commercial potential. We intend to differentiate ourselves within the botanical dietary supplement marketplace by backing proprietary products and promotion with quality research, development and manufacturing, a carry-over from our 35 pharmaceutical culture and skill base. Given consumer demand for quality and the relative lack of specific regulatory standards in the dietary supplement industry, we intend to set our own high standard for quality and product standardization for our botanical products. We intend to develop standardization processes for the ingredients in all our products, including safety verification and, where appropriate, human clinical testing of potential products. Once completed, published clinical data can be utilized for educational purposes with consumers and retailers seeking more information about our products. This distribution of "third party" literature for education and promotional sales can be particularly effective with Internet purchases. We believe that these elements, along with unique formulations and existing and future patents, should add to the proprietary position of our products. Product Candidates Our first botanical dietary supplement product will be SB-300, which is designed to normalize water flow in the bowel and promote stool formation. SB-300 is an extract of Croton Lechleri, a plant used by indigenous people for relief of gastrointestinal symptoms, and contains a chemical activity marker, SP-303, a patented, clinically proven antidiarrhea agent. SB-300 also has a patented formulation. The mechanism of SB-300 is a desirable anti-secretory activity, and SB-300 does not have anti-motility effects, such as the side effects of constipation and cramping associated with the use of immodium and loperamide. Such anti-motility agents generally cannot be used on a continuous basis as a result of these side effects. We plan to commercialize this product ourselves through community building initiatives on the Internet and other appropriate focused channels of distribution. We intend to market the product initially to people with HIV/AIDS who suffer from chronic diarrhea, and then travelers and others who suffer from acute bouts of diarrhea. We are also considering developing a pediatric formulation of SB-300, which would complete three distinct commercial product opportunities from one plant extract, differentiated by formulation, packaging, and target customer/community base. We are also working to develop a second product line based on a diet system to mitigate Syndrome X symptoms. Syndrome X is the cluster of metabolic disorders that occur in the face of elevated insulin when an individual is insulin resistant, yet still maintains glucose control and is therefore not diabetic. This cluster of coronary heart disease risk factors, such as elevated triglycerides and lower HDL-cholesterol, the "good" cholesterol, are the silent killers associated with Syndrome X. Shaman's Sr. Vice President of Clinical Research, Dr. Gerald Reaven, has developed a trademarked Syndrome X diet system for persons exhibiting Syndrome X symptoms, and has performed over 20 years of clinical research documenting the benefits of this diet system. Direct comparison clinical trial data supports that this diet system provides superior benefits to those exhibiting Syndrome X symptoms than the low fat/high carbohydrate diet guidelines recommended by the American Heart Association. Approximately 30% of the US population is insulin resistant and subject to Syndrome X. We anticipate that a product line would include bars, drinks, and snacks which follow the trademarked anti-Syndrome X diet system, infused with proprietary Shaman botanicals to address further these metabolic disorders. Many people with AIDS/HIV who are effectively managing the AIDS virus with their antiviral therapies are now also demonstrating metabolic abnormalities consistent with insulin resistance and Syndrome X and progressing to coronary heart disease and type II diabetes. We intend to leverage the identity we will work to establish in the AIDS/HIV community through our SB-300 product to commence marketing of our Syndrome X diet system in this community, and intend to initially target this community. Future Product Candidates We have strategically identified multiple areas of dietary supplement product interest and have identified specific priority product candidates for the future based on four criteria: * key market categories with significant commercial potential, * the needs of an aging demographic in the U.S. population, * areas where quick, symptomatic relief could be observed, and * areas where we have first-hand ethnomedical experience and where sustainable supply of raw materials exists. Some of these proposed product areas include gastrointestinal relief, sexual function aids, antioxidants/cardiovascular protectors, sleeping aids, calming agents and weight management. 36 Another potential product opportunity is a proprietary, enhanced formulation of one of the world's leading phytomedicines. We have filed a patent application for this product. We believe this product represents a significant out-licensing opportunity. All of these potential products are based on plant material on the FDA's grandfathered old dietary ingredient list, which includes dietary ingredients that were sold in the United States prior to 1994, allowing for immediate product introduction without a need for regulatory application or approval. We believe our current and prior research and development efforts would allow us to introduce up to eight products, including human clinical testing, within the first two years of our botanicals operations. We believe that all of these product areas offer significant opportunity for growth. Products in these areas may be developed for sale under the Shaman brand name in the future, or selectively out-licensed. Sales and Marketing Our first product launch will be SB-300, a botanical dietary supplement to normalize water flow in the bowel and promote stool formation. SB-300 will initially be targeted to people with AIDS/HIV who suffer from chronic diarrhea. We plan to market SB-300 via the Internet, 1-800 direct response advertising, limited storefront access in major market cities, and focused mail order opportunities. In addition, Shaman is working with several leading treatment activists to have them feature the introduction of this product in their regional organizations' newsletters. We expect to begin marketing SB-300 commencing in the third quarter of 1999. Commencing in the fourth quarter of 1999, we also intend to market SB-300 to travelers and others suffering from acute episodes of diarrhea. The product will be differentiated from that targeted to the AIDS/HIV community in that it will be a lower dose and packaged in smaller quantities to address the nature of its expected use in the target customer base. We believe that selling a traveler's health-related product on the Internet presents an attractive marketing opportunity since two primary uses of the Internet are currently healthcare information and travel. We intend to market this product with banner advertising at affiliate travel web sites and point of purchase at high-risk diarrhea destinations, sample programs to adventure travel and tour companies traveling to such areas, and other highly focused target customer programs. In marketing a diet system product line to address Syndrome X symptoms, we intend to leverage the identity we will work to establish in the AIDS/HIV arena through sales of SB-300, and will initially target this community. Similarly to SB-300, we believe we will be able to implement efficient and focused promotion and distribution to the AIDS/HIV community, and then expand our marketing efforts to focus on mass market indications. Thus, our initial customer base communities will include: - people with AIDS/HIV suffering from chronic diarrhea; - travelers to high-risk diarrhea destinations; - people with AIDS/HIV exhibiting Syndrome X symptoms - the Syndrome X population at large. Both diarrhea and Syndrome X appear to be under-served and under-recognized on most Internet healthcare sites. We believe that the features to be offered on our web site relating to information on these health issues, together with the exclusive access of our web site to our proprietary products, presents an opportunity for our website to become one of the definitive sites for the communities affected by these health concerns for complementary medical alternatives. Customers and Partners The market for dietary supplements in the United States is growing. In recent consumer surveys, 25% to 30% of consumers report having utilized a botanical dietary supplement, and 36% report moderate to heavy use of complementary medicine. We believe that our botanicals business has two key initial classes of customers: * consumers, primarily in the HIV/AIDS community, the traveler's market, and Syndrome X community to whom we intend to market our first product, SB-300, and our anticipated second anti-Syndrome X diet product line; and * mass market and multi-level companies that are interested in licensing or partnering with us for the commercialization of our products. 37 Potential SB-300 customers Diarrhea in people with HIV and AIDS is a devastating syndrome. In 1997 in the United States, there were an estimated 225,000 people with AIDS and between 650,000 and 900,000 individuals in the United States were believed to be infected with HIV. While fewer people are dying of AIDS, new cases of AIDS and HIV are still increasing and people are now living longer with both AIDS and HIV. Sources indicate that, of the combined HIV and AIDS population in the United States, approximately 20% to 40% suffer from diarrhea at any given time, with an average duration of 90 days per year. Although protease inhibitors and highly active antiretroviral therapy have improved the prognosis for people living with HIV and AIDS, the problem of diarrhea persists. In the majority of cases the symptom is thought to be related to the anti-viral drugs. Diarrhea therefore remains a serious problem that has not been adequately addressed. Diarrhea not only compromises the health and quality of life of individuals with AIDS and HIV but also has been shown to increase dramatically the cost of these individuals' medical care. Furthermore, people with chronic diarrhea are forced to restrict their daily activities to accommodate the disruptions caused by this condition because current symptomatic therapies provide either poor relief or undesirable side-effects. We believe that a product that normalizes water flow in the bowel and promotes stool formation represents a large, focused and untapped market opportunity. We believe that the competitive promotional response may be limited in this discrete market because no specific dietary supplements or over-the-counter antidiarrheals have targeted this population to date, likely because there are no indication or studies in this patient population and the mechanism of action of anti-motility products is counter-indicated for chronic diarrhea. Further, we hope eventually to build a niche market position by catering specifically to the needs of the HIV/AIDS community with a full product line. For the traveler's market, SB-300 provides a natural alternative to currently available treatments which have unpleasant side effects, such as constipation and rebound diarrhea. More than 35 million individuals travel annually to countries that present the risk of traveler's diarrhea. Potential Partners We are actively engaged in partnering discussions with top tier companies in both the mass market and multi-level dietary supplement arenas. No agreements have been reached or entered into to date. We are focusing our partnering efforts initially on the multi-level market arena and then intend to focus on a large mass market, heavily promotional, healthcare deal which will require a longer period of time to negotiate. Mass Market The entrance of large healthcare and consumer products companies into the dietary supplement industry has fueled the expanded placement of botanical dietary supplements beyond local health food stores and into neighborhood grocery stores, drug stores and mass merchandisers. To promote this placement, these companies are spending huge sums on advertising and promotion relative to previous marketing budgets for dietary supplements that rarely topped $1 million. For example, in 1998, American Home Products Corporation spent an estimated $12 million on its Centrum(R) line, Bayer Corporation spent an estimated $35 million on its One-A-Day(R) line of eight products, and Warner-Lambert Company spent an estimated $15 million on its Quanterra(R) line of two products. Such large promotional expenditures are relatively recent because historically sales of single products or even lines of products rarely passed the single-digit million mark. However, industry analysts now report much higher sales figures. For example, American Home Products, Bayer and Warner-Lambert are forecasting combined first year sales of over $100 million for their botanical lines, largely a result of significant promotion. Through increased promotional budgets, companies such as these are educating more consumers about the benefits of herbal and botanical products, thereby increasing consumer trial and repurchase. If these trends continue, the growth of the botanical dietary supplement market could far surpass growth in the past. Each of these product lines is simply a new opportunity of commodity botanical products. We believe that another key driver of continued growth will be the introduction of new botanical dietary supplement products. Introduction of new products has in the past not only brought new consumers into the market but also fueled the purchase of other existing botanicals. The large healthcare and consumer products companies are currently tapping into the commonly known commodity botanical products, primarily of European origin. Once growth of these products is maximized, novel proprietary products will be needed, and we believe we are uniquely positioned to meet this need in certain market areas. We plan to partner with mass market companies in order to expand the advertising and promotion of our botanical dietary supplement products. Such a partnership would combine the benefits of our new products with the partner's 38 ability to generate large advertising and public relations campaigns for our new product lines, similar to those created for existing consumer product lines. In addition, we could pursue a licensing arrangement, such as that completed between PharmaPrint, Inc. and American Home Products, in which the Shaman name could be co-branded with a product or product line with a partner. Multi-Level Multi-level marketing is a system of network marketing comprised of two components: one-on-one selling and yearly sales conventions. Distributors, usually individuals looking for a home-based business or the opportunity to supplement their regular income, sell products to friends and relatives. Distributors are incentivized to sign-up their friends as distributors, and they receive in return an incentive for all the sales in their network. Hence, the impact is that of an ever-growing customer base that is somewhat captive and more predisposed to purchase than the broad consumer public. In addition, this type of selling makes the emotional impact of product stories very important, as distributors need to believe in the products they are selling to friends. The primary form of promotion in the multi-level marketing channel, beyond one-on-one selling, is the yearly sales convention. Each year, all distributors are brought together for a multi-million dollar sales convention. On-stage presentations are given on four to five key new products, or a product line, being launched in the coming year. The history of the products, testimonials and their uses are discussed. Then, distributors are sent back to their homes for another year of selling. During the year, incentives may be given for reaching certain sales quotas on a particular product or product line. Dietary supplements have been a mainstay of the multi-level marketing industry. However, botanicals are a newer player on the scene. Some multi-level firms such as AmWay Corporation, with its NutriLite line, and Nu Skin Enterprises, Inc. have embraced the commonly used commodity botanicals. However, it is new products that fuel the growth in multi-level marketing. Our botanical products lend themselves to this market for several reasons. We have truly novel products--the lifeblood of this distribution channel. Further, the origins of our products are unique and lend themselves to the type of interesting and emotionally compelling selling stories required for peer-to-peer selling. These would make for entertaining sales convention presentations, featuring famous ethnobotanists and the rainforest. Additionally, our reciprocity and conservation policies provide interesting content for responsible and compelling story-based selling. Internet We intend to use Internet marketing of our proprietary products as a means to achieve high-end branding of our products. We believe that this exclusive access to our proprietary products may be the most important advantage of our ShamanBotanicals.com e-commerce site. The Internet offers an opportunity to provide, within the requirements of the Dietary Supplement Health and Education Act, easily and quickly accessible third-party literature and supportive information on-line. We expect to offer bulletin board postings, community chat rooms, patient security and customization as features on our web site. We also expect to have exclusive access to certain medical experts for medical commentary. Affiliate programs are expected to be important. For example, since diarrhea appears as a side effect in the labeling of over 80% of pharmaceuticals, the indication for our product SB-300 of normalizing water flow in the bowel and promoting stool formation, provides a natural link between the problem caused by these pharmaceutical products and the solution offered by SB-300. Finally, information on our reciprocity programs will be available as well. Competition Competition in the botanical dietary supplement market differs by channel of distribution. Historically, competition within the health food channel was fragmented and made up of over 200 small, mostly privately held companies. More recently, several large consumer healthcare companies have opened up the mass-market channel, including American Home Products with its Centrum(R) Herbal brand, Bayer's introduction of botanical ingredients in their One-A-Day(R) line, and Warner-Lambert's introduction of their Quanterra(R) brand. Overall, the entrance of these companies is expected to broaden consumer acceptance of botanical products and grow the total botanical dietary supplement market, with the mass market becoming the largest, fastest-growing distribution channel. In order to enter this key channel, we intend to partner with a company with direct to consumer promotional capabilities and extensive experience in this market. We believe that a partner in this channel will value the quality and scientific rigor behind our products. In the multi-level marketing channel, key players include Shaklee Corporation, Nu Skin Enterprises, Inc., USANA, Inc. and OmniLife. Again, we intend to partner with a top-tier company in this channel. We believe that 39 partners in this channel will appreciate the novel products we have to offer and the compelling stories of their rainforest and traditional use origins. There is currently no established leader in marketing dietary supplements through the Internet, although several Internet sites do exist, including AllHerb.com, Mothernature.com, and Greentree.com. The emerging "drugstore " sites such as Drugstore.com and PlanetRx.com also carry some dietary supplements. We intend to start our own website within this distribution channel, with the unique attraction of our own, proprietary products available on the site, particularly targeting the HIV/AIDS community. We have reserved the Internet domain name "ShamanBotanicals.com." We do not expect to compete head-to-head with the existing Internet sites, where there has been little differentiation between sites with respect to product offerings. Rather, ShamanBotanicals.com will focus first on the needs of the HIV/AIDS community, including information and nutritional products particularly important for people with diarrhea and other associated problems. The design of our website will be integral to the launch and sale of our first product, SB-300, via the Internet distribution channel, and other community building initiatives. Government Regulation The term "botanical dietary supplement" is defined by the 1994 Dietary Supplement Health and Education Act as "an herb or other botanical or a concentrate, constituent, extract or combination of any botanical that is intended for ingestion as a tablet, capsule, or in liquid form and is not represented for use as a conventional food or as a sole item of a meal or the diet and is labeled as a dietary supplement." The 1994 Dietary Supplement Health and Education Act specifically outlines how botanical products are to be regulated and treated. Some commonly known commodity botanical dietary supplement products include ginseng, gingko biloba, St. John's wort, and echinacea. This statutory definition also differentiates botanical dietary supplements, vitamins and minerals from conventional foods or food additives. Under the law, botanicals may be sold as dietary supplements with claims as to their effect on the structure or function of the human body, providing the seller has adequate documentation for the claims. Botanical dietary supplements are regulated by the FDA. However, some botanical dietary supplement products require no review or approval to enter the market, while some new products may require the submission of basic safety data prior to marketing. As a result, the FDA regulatory process in the botanical dietary supplement industry is much less rigorous than in the pharmaceutical industry, allowing for much faster market introduction. One of the unique provisions of DSHEA is the distinction between new dietary ingredients and old dietary ingredients, which had a history of being marketed in the United States prior to DSHEA. Old dietary ingredients have been "grand-fathered" under the law, allowing them to be commercialized without further FDA review. Our pipeline includes more than 400 botanical candidates that are old dietary ingredients, including several near-term product candidates, and numerous new dietary ingredients candidates. Pharmaceuticals Background Pharmaceutical companies continually search for innovative products available for in-license to enhance their existing product portfolios. Products that have an entirely different approach or means of accomplishing the desired therapeutic effect than products currently available are particularly in demand. In addition, companies are looking to develop or in-license products that may be more effective and/or less costly than those currently available, or those that could offer an alternative to other, more invasive forms of medical treatment and address the self-medication and quality of life issues of the current aging consumer population. Strategy Until recently, we were primarily focused on discovering and developing novel pharmaceutical products for major human diseases by isolating and optimizing active compounds found in tropical plants with a history of medicinal use. We have conducted human clinical trials with our three lead product candidates -- SP-303/Provir (Phase III/II), nikkomycin Z (Phase I) and SP-134101 (Phase I) -- targeting five indications. Due to unforeseen delays and costs necessary to complete additional trials for our lead compound, SP-303/Provir for the treatment of diarrhea in people with AIDS, we have chosen to discontinue all pharmaceutical development, manufacturing and marketing activities. We now intend to out-license worldwide marketing rights to our pharmaceutical assets. Product Discovery and Development Process In our efforts to develop pharmaceutical products we previously focused on drugs extracted from plants with a long history of medicinal use. Through this process, we successfully identified and developed a number of pharmaceutical 40 candidates, particularly through the preclinical and early clinical stages. These efforts have produced a portfolio of product candidates for out-license. Product Candidates We conducted human clinical trials with our three leading product candidates -- SP-303/Provir (Phase III/II), nikkomycin Z (Phase I), and SP-134101 (Phase I) -- targeting five indications. We have discontinued all pharmaceutical development, manufacturing and marketing activities and plan to out-license all of the pharmaceutical applications of our technology. The following table describes the major therapeutic areas in which we have had active product development and research. Efforts are being made to out-license all of these pharmaceutical products: Product Indication Status Commercial Rights - ------- ---------- ------ ----------------- Provir AIDS-associated Completed Phase III Shaman diarrhea study in Q4, 1998. Completed a Phase II efficacy study in Q4, 1997 Provir Watery diarrhea Completed two Phase II Shaman efficacy trials in Q3, 1998. Completed initial Phase II efficacy studies in 1996 & 1997 Provir Pediatric Formulation to be Shaman diarrhea developed Nikkomycin Z Endemic mycoses Completed Phase I study Shaman in Q2, 1997. Nikkomycin Z Azole-resistant Initiation of clinical Shaman and Azoles Candida program pending pre- clinical development by Pfizer SP-134101 Type II Diabetes Completed Phase I study Shaman in Q1, 1998 Oral Type II Diabetes Preclinical, Ono; Lipha/Merck; antihyperglycemic 29 compounds and Shaman. Shaman compounds receives royalties on sales outside the U.S. and profit sharing in the U.S. Sales and Marketing We intend to out-license worldwide marketing rights to our pharmaceutical assets. Customers and Partners We continue to pursue discussions for the out-licensing of our pharmaceutical assets. In September 1996, we entered into a five-year collaborative agreement with Lipha/Merck to develop jointly our antihyperglycemic drugs. We are currently in negotiations with Lipha/Merck for the discontinuation of this research agreement. Lipha/Merck will make no further research payments. We are in discussions with Lipha/Merck regarding the dissolution of this relationship. In May 1995, we entered into a collaborative agreement with Ono Pharmaceutical Co. Ltd. providing for, among other things, three years of funding for the research and development of compounds for the treatment of Type II diabetes. Although the on-going research funding period under such agreement has expired, Ono continues to have contractual obligations to us for the potential payment of milestones and royalties. There can be no assurance that such milestones will be attained or that we will receive any future milestone payments or royalties from Ono. 41 Competition The out-licensing of pharmaceuticals is a competitive enterprise. Although many companies consider licensing opportunities, they often investigate multiple opportunities before settling on a select few. While Shaman is subject to this competition, we have had significant interest in our products based upon their novelty, safety, efficacy, and advanced stages of development. We are actively seeking to out-license our products and we have multiple on-going discussions. To date, these discussions have not resulted in any out-licensing agreements. Patents and Proprietary Rights Proprietary protection for our product candidates, processes and know-how is important to our business. Our policy is to file patent applications to protect technology, inventions and improvements that are considered commercially important to the development of our business. We also rely upon trade secrets, know-how and continuing technological innovation to develop and maintain our competitive position. We aggressively prosecute and defend our patents and proprietary technology. We have 20 U.S. patents issued to date. In addition, we currently have 12 U.S. patent applications pending with the U.S. Patent and Trademark Office and multiple applications filed under the Patent Cooperation Treaty. We do not know whether any of these applications will result in the issuance of any patents or, if any patents are issued, whether any issued patent will provide significant proprietary protection or will be circumvented or invalidated. We have been issued a U.S. patent related to our specific proanthocyanidin polymer compositions designated SP-303/Provir. Specifically, the patent contains composition of matter claims related to SP-303/Provir contained in our SP-303/Provir product. We have also filed foreign applications corresponding to our issued U.S. patents relating to our proanthocyanidin polymer composition. We have been granted patents in Australia, Mexico and New Zealand and have patent applications pending in Canada, Europe, Japan, the Republic of Korea and Singapore. We have also filed a U.S. patent application directed to new formulations and methods of using our specific proanthocyanidin polymer composition for treatment of watery diarrhea. These formulations are contained in our SP-303/Provir product. We have 10 issued U.S. patents relating to compositions and methods for treating Type II diabetes, as well as reducing hyperglycemia associated with other etiologies. We also have eight additional U.S. patent applications pending that relate to compositions and methods for treating Type II diabetes, as well as reducing hyperglycemia associated with other etiologies. We have filed 11 international applications under the Patent Cooperation Treaty designating a number of foreign countries, as well as applications in Taiwan, corresponding to eleven U.S. applications and plan to file additional corresponding foreign applications within the relevant convention periods. We also have one issued U.S. patent and corresponding international patent applications in a number of foreign countries relating to methods for administering and sustained release formulations for anti-fungal agents like nikkomycin Z. The methods and compositions are useful for treatment of fungal infections, particularly candidiasis, the most frequently encountered life-threatening mycoses. We have licensed several patents from Bayer AG relating to the use of nikkomycin Z and the composition and use of nikkomycin Z in combination with other antifungal compounds for the development of antifungal agents. There can be no assurance that our pending patent applications will result in patents being issued or that, if issued, patents will afford protection against competitors with similar technology; nor can there be any assurance that others will not obtain patents that we would need to license or circumvent. See "Risk Factors--Uncertainty Regarding Patents and Proprietary Rights; Current Legal Proceedings Regarding Patents and Proprietary Rights." Community Commitment The Healing Forest Conservancy In January 1990, we formed The Healing Forest Conservancy, a California not-for-profit public benefit corporation which is dedicated to maintaining global biocultural diversity. The Conservancy focuses on conserving plants that have been used traditionally for medicinal and health purposes and conserving the knowledge of cultures that utilize them. We have donated 667 shares of our common stock to the Conservancy's endowment fund. We also plan to donate additional funds when we have achieved profits from product sales, if any, to provide benefits to indigenous peoples in the countries where our source plants are obtained. 42 The Shaman HIV Investment Trust In 1998, we made a commitment to create the Shaman HIV Investment Trust, which provides funding for charitable causes within the HIV/AIDS Community, including services, education and research. We have committed to the Trust a royalty on the first five years of U.S. product net sales of SB-300 which are sold in the HIV/AIDS market. The Trust will be administered independently by a committee of HIV/AIDS community leaders. The Living With AIDS Initiative As part of Shaman's Living with AIDS reciprocity initiative, we are supporting the Trekking with AIDS Dawn Averitt program. Dawn is a 30 year-old woman who has been living with the HIV virus for 11 years. She is an internationally known treatment activist supporting grass-roots efforts to provide education, empowerment, and treatment for all people with AIDS and HIV. She has recently launched on a five month trek of the Appalachian trail to promote awareness for the challenging quality of life issues associated with living with HIV and AIDS. Her broader message is that we all live with challenges and need to take control of our healthcare and quality of life choices, a message right in line with the goals of product development and commercialization at ShamanBotanicals.com. Employees In February 1999, we ceased operations in our pharmaceuticals business and downsized by approximately 60 employees, or 65% of our workforce. As of June 15, 1999, we had 25 employees. The remaining employees are expected to focus their activities primarily on the botanicals business. 43 MANAGEMENT Executive Officers and Directors The following table sets forth certain information with respect to the executive officers, directors and key employees of Shaman as of June 15, 1999: Name Age Position - ------------------------- --- -------------------------------------------------------------------------------- Lisa A.

Number of Directors; Relationships Our bylaws authorize the board to fix the number of directors serving on the board, provided that such number shall not be less than five nor more than nine. The number of directors is currently fixed at seven. All directors hold office until the second annual meeting of stockholders following the annual meeting of stockholders at which such director was elected, or until their successors have been duly elected and qualified. There are no family relationships among our executive officers or directors. Committees of the Board of Directors Shaman's board of directors has an audit committee which is primarily responsible for annually recommending independent auditors for appointment by the board, for reviewing the services performed by our independent auditors and reviewing reports submitted by the independent auditors. The audit committee includes two directors, Messrs. Titus and Raab. The board also has a compensation committee, which is comprised of Messrs. McDade and Bellamy. The compensation committee reviews and approves our general compensation policies and practices, sets compensation levels for our executive officers and administers our 1992 Stock Option Plan and other employee benefits programs. Director Compensation Each non-employee is reimbursed for reasonable expenses incurred in connection with their attendance at such meetings. The information given below is for historical purposes because each member of the board of directors has agreed to surrender their outstanding options to purchase shares of our common stock. Shaman's non-employee directors receive stock options under our 1992 Stock Option Plan. See "1992 Stock Option Plan." On June 30, 1998, Mr. Berg received an option to purchase 1,000 shares of common stock in connection with his initial appointment to the board pursuant to the automatic grant provision of the 1992 Stock Option Plan. The option has an exercise price of $67.50 per share, the fair market value per share of the common stock on the grant date. Mr. Berg has agreed to surrender these options. On May 15, 1998, Messrs. McDade, Raab, Titus and Bellamy each received an option grant for 375 shares of common stock under the automatic option grant provisions of the 1992 Stock Option Plan. These options have an exercise price per share of $98.75, the fair market value per share of common stock on that date. Each of these directors has agreed to surrender these options. On October 20, 1998, the compensation committee, as administrator of the 1992 Stock Option Plan, implemented an option cancellation/regrant program for certain key consultants and non-employee directors, other than the members of the compensation committee, holding options under the plan. Pursuant to this program, each eligible non-employee director was given the opportunity to surrender his outstanding options under the 1992 Stock Option Plan with exercise prices in excess of $28.75 per share in return for a new option grant for the same number of shares but with an exercise price of $28.75 per share, the closing selling price per share of common stock as reported on the Nasdaq National Market on the October 20, 1998 grant date of the new option. To the extent the higher-priced option was exercisable for any option shares on the October 20, 1998 cancellation date, the new option granted in replacement of that option would become exercisable for those shares in a series of 12 successive equal monthly installments upon the optionee's completion of each month of service over the one-year period measured from the October 20, 1998 grant date. The option would become exercisable for the remaining option shares in one or more installments over the optionee's period of continued service, with each such installment to vest on the same vesting date in effect for that 46 installment under the cancelled higher-priced option. The following non-employee directors participated in the October 20, 1998 cancellation/regrant program with respect to the indicated number of option shares: Mr. Raab, 17,214 shares with a weighted average exercise price of $110.56 per share; Mr. Titus, 2,914 shares with a weighted average exercise price of $128.48 per share; Mr. Berg, 1,000 shares with a weighted average exercise price of $67.50 per share. Each of these directors has agreed to surrender such options. On May 1, 1997, the board of directors approved a consulting arrangement with Mr. Titus, one of its non-employee directors pursuant to which he is to serve as a consultant to Shaman on financing matters and financial operations. Under this arrangement, Mr. Titus was paid consulting fees in the amount of $36,000 for the 1998 fiscal year. This arrangement expired in June 1998. As part of his initial consulting arrangement, Mr. Titus was granted an option to purchase up to 700 shares of common stock under the discretionary option grant program in effect under the 1992 Stock Option Plan. Such option has an exercise price of $107.50 per share, the fair market value of our common stock on the May 22, 1997 grant date of that option and is exercisable in full at any time prior to May 22, 2007. This option was surrendered on October 20, 1998 under the option cancellation/regrant program, in return for a new option grant for the same number of shares but with an exercise price of $28.75 per share. The option would have become exercisable in a series of 12 successive equal monthly installments over the one-year period measured from the October 20, 1998 grant date, however, Mr. Titus has agreed to surrender this option. In August 1995, we entered into a consulting arrangement with Mr. G. Kirk Raab, Chairman of the Board. As consideration for special consulting services Mr. Raab performed under the consulting arrangement, Mr. Raab was paid an annual consulting fee of $100,000. In addition, he was granted an option for 10,000 shares of common stock on August 21, 1995 with an exercise price per share of $110.00, the fair market value per share of common stock on that date. The option was granted under the discretionary option grant provision of the 1992 Stock Option Plan, and the option would have become exercisable in a series of 48 successive equal monthly installments over the four-year period measured from the August 21, 1995 grant date, provided Mr. Raab continued to render services to us pursuant to his consulting arrangement. This option was surrendered on October 20, 1998 under the option cancellation/regrant program, in return for a new option grant for the same number of shares but with an exercise price of $28.75 per share. Mr. Raab has agreed to surrender this replacement option. In addition, in connection with his services as a director and as Chairman of the Board, Mr. Raab received an annual retainer fee of $60,000, payable after each annual meeting of stockholders so long as Mr. Raab continued to render services to us as Chairman of the Board. We paid a total of $66,667 of the consulting fees in cash and on November 7, 1998, issued 6,783 shares of common stock in payment of his consulting services for the 1998 fiscal year. Shaman and Mr. Raab have agreed to terminate the compensation component of his consulting arrangement and no further payments are to be due under this arrangement. Mr. Raab still serves as Chairman of the Board. In January 1999, we entered into a consulting agreement with Mr. Loren D. Israelsen, a director and officer, pursuant to which he served as interim Chief Executive Officer of our ShamanBotanicals.com division. Under this agreement, Mr. Israelsen was paid a total of $30,000 for his services in January and February 1999. In addition, upon further funding of Shaman, Mr. Israelsen is to be paid $10,000 in deferred consulting expenses and an additional $150,000 project retainer to help close a corporate deal for the ShamanBotanicals.com division. Such retainer will be paid in three installments during the third quarter of 1999. Mr. Israelsen will also receive a success payment for each corporate partnership as a percentage of the up front fee received from such partner, which fee varies from two to five percent depending upon the timing of closing such partnership. Compensation Committee Interlocks and Insider Participation During the 1998 fiscal year, Herbert H. McDade and Adrian D.P. Bellamy served as members of the compensation committee of the board of directors. No member of the compensation committee was, at any time during the 1998 fiscal year or at any earlier time, an officer or employee of Shaman. No executive officer of Shaman serves as a member of the board of directors or compensation committee of any entity which has one or more executive officers serving as a member of Shaman's board of directors or compensation committee. 47 Executive Compensation The following table sets forth the compensation earned, for services rendered in all capacities to us, for each of the last three fiscal years by Shaman's Chief Executive Officer and the four other highest paid executive officers serving as such at the end of the 1998 fiscal year whose salary and bonus for that fiscal year was in excess of $100,000. The individuals named in the table will be referred to in this prospectus as the Named Officers. No other executive officer who would otherwise have been included in such table on the basis of fiscal year 1998 salary and bonus resigned or terminated employment during the year.

There can be no assurance that the actual stock price appreciation over the 10-year option term will be at the assumed 5% and 10% levels or at any other defined level. As of March 31, 1999, the exercise price of all options was significantly higher than the trading price of the stock on that date. (2) Each option has a maximum term of 10 years, subject to earlier termination in the event of the optionee's cessation of service with Shaman. Except for the options for 75,000 shares granted to Ms. Conte, 2,000 shares granted to Mr. Khandwala and 500 shares granted to Ms. Peltier, each option granted to the Named Officers in fiscal 1998 were part of the September 18,1998 cancellation/regrant program. Accordingly, to the extent the cancelled option for the same number of shares was exercisable for any of those shares on the September 18, 1998 cancellation date, the new option granted in replacement of that option will become exercisable for those shares in a series of 12 successive equal monthly installments upon his or her completion of each month of service over the one-year period measured from the September 18, 1998 grant date. The option will become exercisable for the remaining option shares in one or more installments over her period of continued service, with each such installment to vest on the same vesting date in effect for that installment under the cancelled option. The options for 75,000 shares to Ms. Conte and 500 shares to Ms. Peltier will become exercisable for 12.5% of the option shares upon completion of 6 months of service measured from the grant date, and the balance of the option shares will become exercisable in a series of 42 successive equal monthly installments over the optionee's 49 period of continued service thereafter. The option for 2,000 shares to Mr. Khandwala will become exercisable in a series of six successive equal monthly installments over the optionee's period of continued service thereafter. However, each of the options granted to the named executive officers will become immediately exercisable in full upon an acquisition of Shaman by merger or asset sale, unless the option is assumed by the successor entity. Each option includes a limited stock appreciation right which will result in the cancellation of that option, to the extent exercisable for vested shares, upon the successful completion of a hostile tender for securities possessing more than 50% of the combined voting power of our outstanding voting securities. In return for the cancelled option, the optionee will receive a cash distribution per cancelled option share equal to the excess of (1) the highest price paid per share of our common stock in such hostile tender offer over (2) the exercise price payable per share under the cancelled option. (3) The exercise price may be paid in cash or in shares of common stock valued at fair market value on the exercise date, or through a cashless exercise procedure involving a same-day sale of the purchased shares. We may also finance the option exercise by loaning the optionee sufficient funds to pay the exercise price for the purchased shares and the federal and state income tax liability incurred by the optionee in connection with such exercise. The optionee may be permitted, subject to the approval of the compensation committee, as administrator of the 1992 Stock Option Plan, to apply a portion of the shares purchased under the option or to deliver existing shares of common stock in satisfaction of such tax liability. (4) Ms. Conte has agreed to surrender all of her currently held options. (5) We accepted the resignation of Dr. Khandwala effective October 2, 1998. (6) Dr. Pennington was terminated effective February 19, 1999 due to the elimination of his position in connection with our restructuring. Option Exercises and Holdings The following table provides information with respect to the Named Officers concerning the exercise of options during the 1998 fiscal year and unexercised options held as of December 31, 1998. No stock appreciation rights were exercised during such fiscal year, and except for the limited stock appreciation right described in footnote (2) to the Stock Option/SAR Grants Table which forms part of each outstanding stock option, no stock appreciation rights were outstanding at the end of that fiscal year.

(5) Dr. Pennington was terminated effective February 19, 1999 due to the elimination of his position in connection with our restructuring. Option Repricings We implemented a special option cancellation/regrant program for all of our employees, including executive officers, holding stock options with an exercise price per share in excess of the fair market value of our common stock on the regrant date. The cancellations/regrants were effected on September 18, 1998, and a number of outstanding options with an exercise price in excess of $25.62 per share were surrendered for cancellation and new options for the same aggregate number of shares were granted with an exercise price of $25.62 per share. The following table sets forth information with respect to each of the Named Officers concerning his or her participation in the option cancellation/regrant program effected on September 18, 1998. We have not implemented any other option cancellation/regrant programs in which our executive officers have participated.

(2) Ms. Conte has agreed to surrender all of her currently held options. (3) We accepted the resignation of Dr. Khandwala effective October 2, 1998. (4) Dr. Pennington was terminated effective February 19, 1999 due to the elimination of his position in connection with our restructuring. 51 1992 Stock Option Plan Our 1992 Stock Option Plan was adopted by the board of directors on December 16, 1992, and has been amended several times since its adoption. The 1992 Stock Option Plan will terminate on December 31, 2008. As of June 15, 1999, 7,000,000 shares of common stock have been authorized for issuance under the 1992 Stock Option Plan. In addition, on February 1, 2000, the number of shares of common stock issuable under the 1992 Stock Option Plan will automatically increase by that number of shares which, when added to the number of shares subject to then outstanding options under the 1992 Stock Option Plan and the number of shares available for future option grant under the 1992 Stock Option Plan immediately prior to such increase, will equal the lesser of (i) 25,000,000 shares or (ii) twenty percent (20%) of the sum of (i) the number of voting shares of Shaman's capital stock outstanding at that time plus (ii) the number of shares of common stock subject to the then outstanding options under the 1992 Stock Option Plan plus (iii) the number of shares available for future option grant under the 1992 Stock Option Plan, after taking such increase into account. As of July 13, 1999, approximately 27,608 shares of common stock had been issued under the 1992 Stock Option Plan, 60,970 shares of common stock were subject to outstanding options, and 6,911,422 shares of common stock were available for future option grant. The share reserve under the 1992 Stock Option Plan has an automatic share increase feature. Subject to adjustment from time to time, the maximum number of shares of common stock for which any one individual participating in the 1992 Stock Option Plan may be granted stock options or separately exercisable stock appreciation rights per calendar year, beginning with the 1999 calendar year, is 5,000,000 shares. The 1992 Stock Option Plan contains two separate option grant programs: * A discretionary option grant program under which key employees, non-employee directors and consultants may be granted options to purchase shares of common stock at a fixed price per share, and * An automatic option grant program under which eligible non-employee directors will automatically receive a special one-time option grant. Options granted under the discretionary option grant program are either incentive stock options designed to meet the requirements of Section 422 of the Internal Revenue Code or non-statutory options not intended to satisfy such requirements. All grants under the automatic option grant program are non-statutory options. The board of directors may terminate the 1992 Stock Option Plan at any time. Any options outstanding at the time of such termination will continue to remain outstanding and exercisable in accordance with the terms and provisions of the instruments evidencing those grants. The 1992 Stock Option Plan will, however, automatically terminate on the date all shares available for issuance are issued as vested shares or cancelled pursuant to the exercise, surrender or cash-out of outstanding options under the plan. Discretionary Option Grant Program The compensation committee of the board of directors administers the discretionary option grant program. The compensation committee, as administrator of this program, has full authority to determine the eligible individuals who are to receive option grants and/or stock appreciation rights, the type of option, either incentive stock option or non-statutory stock option, or stock appreciation right, either tandem or limited, to be granted, the number of shares to be covered by each granted option or right, the date or dates on which the option or right is to become exercisable and the maximum term for which the option or right is to remain outstanding. Options granted under this program may either become exercisable in periodic installments over the individual's period of service or may be immediately exercisable for all the option shares at the exercise price paid per share in the event the individual leaves our service prior to vesting in these shares. Under the discretionary option grant provision of the 1992 Stock Option Plan, we may grant options, for incentive stock option grants, at an exercise price equal to the fair market value on the date of grant or, for non-statutory grants, at an exercise price less than, equal to or greater than the fair market value of the common stock on the date of grant. No option may be granted with a term exceeding ten years. However, each such option may be subject to earlier termination within a designated period following the optionee's cessation of service with us. Options are not assignable or transferable by the optionee except by will or the laws of inheritance following the optionee's death. The optionee will not acquire any shareholder rights with respect to the option shares until the option is exercised and the purchase price is paid for the shares. The option price may be paid in cash or in shares of common stock held by the optionee. The compensation committee may also permit an option holder to pay the option price for the purchased shares through a loan payable in installments over a period of years. 52 In the event we are acquired, whether by a merger or asset sale, each option at the time outstanding will automatically become exercisable for all of the option shares at the time subject to such option and may be exercised for any or all of such shares. However, an outstanding option will not so accelerate if it is to be assumed by the successor corporation or the acceleration of such option is subject to other limitations imposed by the compensation committee at the time of the grant. The compensation committee also has full power and authority, exercisable either at the time the option is granted or at any time while the option remains outstanding, to provide for the automatic acceleration of one or more outstanding options in the event of a change in control of Shaman, whether by hostile tender offer for more than 50% of the outstanding voting stock or proxy contest of the election of board members, so that each such option will become exercisable, immediately prior to such change in control, for the total number of shares of common stock at the time subject to such option. Should an option expire or terminate for any reason prior to exercise in full, the shares subject to the portion of the option not so exercised will be available for subsequent grant under the 1992 Stock Option Plan. In addition, unvested shares issued under the Plan and subsequently repurchased by us at the option exercise price paid per share will be added back to the share reserve and will accordingly be available for subsequent issuance under the 1992 Stock Option Plan. However, shares subject to any option surrendered or cancelled in accordance with the stock appreciation right provisions of the 1992 Stock Option Plan will not be available for subsequent grants. Automatic Option Grant Program All grants under the automatic option grant program must be in strict compliance with the express provisions of that program and no administrative discretion will be exercised by the compensation committee of the board of directors. Under the automatic option grant program each non-employee director will receive: * On February 1, 2000, a one-time option grant if he or she is serving as a non-employee director at that time. The option will allow each such non-employee director to purchase that number of shares of common stock equal to one half of one percent of the number of voting shares of Shaman's capital stock outstanding at that time; and * Upon his or her initial appointment or election to the board of directors, a special one-time option grant for that number of shares of common stock equal to one half of one percent of the number of voting shares of Shaman's capital stock outstanding on February 1, 2000, provided such individual has not previously been employed by Shaman. Each option granted under the automatic option grant program will have an exercise price per share equal to the fair market value per share of common stock on the grant date payable in cash or shares of common stock, and a maximum term of ten years, subject to earlier termination upon the optionee's cessation of board service. The grant will become exercisable for the option shares in a series of 48 successive equal monthly installments over the optionee's period of continued board service, measured from the grant date. However, the option will become immediately exercisable for all of the option shares in the event of an acquisition of Shaman by merger or asset sale or a hostile takeover by tender offer for more than 50% of the outstanding voting stock or proxy contest for board membership. In addition, each option grant will be automatically cancelled upon the successful completion of a hostile tender offer for more than 50% of Shaman's outstanding voting securities. In return, the optionee will be entitled to a cash distribution from Shaman in an amount per cancelled option share equal to the excess of (1) the highest price per share of common stock paid in connection with the tender offer over (2) the exercise price payable for such share. 401(k) Plan We have a tax qualified salary deferral program under Section 401(k) of the Internal Revenue Code. Under this program, any employee of Shaman may elect to contribute up to 20% of his or her eligible earnings per pay period, up to the maximum amount permitted per calendar year under the Federal tax laws. The contributed earnings are credited to the employee's account under the 401(k) Plan, and the account is held in trust as part of the plan assets. Each account under the 401(k) Plan will be adjusted periodically to reflect its share of the investment gains, earnings and losses of the trust fund, and the employee may receive an in service loan distribution until the individual leaves Shaman's employ, dies or becomes disabled. Alternatively, a terminated employee may defer the distribution of the account balance until age 65. Although the 401(k) Plan permits us to make contributions to the plan which either match in whole or in part the salary deferral contributions made by the participants or which are otherwise to be allocated to the accounts of participants on the basis of their eligible earnings for the plan year for which such contribution is made, we have to date made no contributions to the 401(k) Plan. 53 Employment Contracts, Termination Agreements and Change of Control Agreements On March 15, 1999, the board of directors approved a change in control provision concerning severance benefits for key executives. Pursuant to this provision, should their employment with us terminate within 12 months after a change in control, for any reason other than for cause, they will be entitled to receive in one lump sum payment the cash equivalent of 12 months of base salary plus any benefits to which they would otherwise be entitled. In connection with these severance benefits, we have agreed to pay the premiums for any COBRA coverage to which these individuals or their spouse or dependents are entitled under a company sponsored medical plan after a change in control. In addition, in the event of a change in control, all of the options held by such key executives will automatically become fully vested and exercisable. Such executives' exercisable shares will be fixed at the termination of their employment, and they will have a period of 90 days from their termination date to purchase such exercisable shares, as set forth in the stock option agreements applicable to their options. On May 27, 1998, we entered into a letter agreement with Stephanie C. Diaz pursuant to which she served as Vice President, Chief Financial Officer, commencing in June 1998. Pursuant to the letter agreement, Ms. Diaz was paid an annual salary of $135,000 in addition to a $15,000 sign-on bonus. In addition, Ms. Diaz was granted an option for 2,250 shares of common stock on June 30, 1998 with an exercise price per share of $67.50, the fair market value per share of common stock on that date. The option became exercisable for 12.5% of the option shares upon completion of six months of employment and for the balance of the option shares in 42 equal monthly installments over the next 42 months of employment. In the event Ms. Diaz's employment is terminated other than for cause, she was to be paid salary and benefits for six months or until she obtained full-time employment, whichever occurs first. Ms. Diaz resigned from Shaman effective January 4, 1999. In connection with a revised agreement, Ms. Diaz received a payment of three months salary and the continuance of the exercise period under existing options for a period of 12 months following termination of her employment. On March 30, 1998, we entered into a letter agreement with John W.S. Chow, Ph.D. pursuant to which he was served as Vice President, Technical Operations, commencing in May 1998. Pursuant to the letter agreement, Dr. Chow was to be paid an annual salary of $165,000 in addition to the sign-on bonus paid to him in the amount of $10,000, and he was to be reimbursed, in an amount not to exceed $25,000, for closing costs incurred in the sale of his former residence in New Jersey and the purchase of his new residence in the Bay Area. Dr. Chow will, however, be obligated to repay a prorated portion of both the sign-on bonus and the reimbursed closing costs should he resign from Shaman within two years after his hire date. Dr. Chow was also granted an option for 2,500 shares of common stock on May 15, 1998 with an exercise price per share of $98.75, the fair market value per share of common stock on that date. The option will become exercisable in a series of monthly installments over the four year period measured from the grant date as follows: 10% of the option shares will become exercisable upon his completion of six months of employment measured from such grant date, an additional 30% of the option shares will become exercisable in a series of 18 successive equal monthly installments upon his completion of each additional month of employment over the next 18 months thereafter, and the remaining 60% of the option shares will become exercisable in a series of 24 successive equal monthly installments upon his completion of each additional month of employment during the 3rd and 4th years of employment measured from the grant date. Dr. Chow was also granted an additional 750 shares of common stock on May 15, 1998 with an exercise price of $98.75, the fair market value per share of common stock on that date. The 750 share grant will become exercisable as follows: 375 shares upon Dr. Chow's completion of three years of employment measured from the grant date, and the remaining 375 shares upon his completion of four years of employment measured from the grant date. We further agreed to pay Dr. Chow's reasonable moving expenses in an amount not to exceed $20,000 and to provide him with an apartment for up to four months at a rental not to exceed $2,500 per month. Should we terminate Dr. Chow's employment for any reason other than for cause prior to May 1, 2001, we would continue to pay Dr. Chow's base salary plus benefits on a monthly basis for up to six months or until Dr. Chow obtains near full-time employment or consulting of at least 80% of his time, whichever occurs sooner. We also extended a $300,000 loan to Dr. Chow in connection with his purchase of a new residence in the Bay Area. See "Certain Relationships and Related Transactions." On August 21, 1997, we entered into a letter agreement with James Pennington, Ph.D. pursuant to which he served as Senior Vice President, Clinical Research and Chief Medical Officer, commencing October 1997. Pursuant to the letter agreement, Dr. Pennington was paid an annual salary of $255,000 in addition to a sign-on bonus paid to him in the amount of $60,000. In addition, Dr. Pennington was granted, on September 16, 1997, an option to purchase 6,250 shares of common stock at a purchase price of $121.25 per share. The option had a term of 10 years and was to become exercisable as follows: 12.5% of the option shares upon Dr. Pennington's completion of six months of service, measured from the grant date, and the balance of the option shares in 42 successive equal monthly installments upon his completion of each of the next 42 months of service thereafter. In the event that Dr. Pennington's employment is terminated other than for cause, he would be entitled to receive salary and benefits for nine months, or, if sooner, until Dr. Pennington obtained near full time employment or consulting of at least 80% of his time. On February 15, 1999, we entered into a new agreement with Dr. Pennington in connection with his resignation as Senior Vice President, Clinical Research and Chief Medical Officer, effective February 19, 1999. Under this agreement, payments were made to Dr. Pennington until June 1999, at which time he secured employment elsewhere 54 and his severance payments were terminated. In addition, options previously granted to him will continue to vest during this period following his termination. On February 9, 1996, we entered into a letter agreement with Atul S. Khandwala, Ph.D. pursuant to which he served as Senior Vice President, Development, commencing March 1996. Pursuant to the letter agreement, Dr. Khandwala was paid an annual salary of $225,000. In addition, Dr. Khandwala was granted an option to purchase 6,000 shares of common stock at a purchase price of $137.50 per share. The option had a term of ten years and would become exercisable over a four-year period in a series of 48 successive equal monthly installments upon Dr. Khandwala's completion of each month of service with Shaman over the four-year period measured from March 1, 1996. In the event Dr. Khandwala's employment is terminated by us for any reason, Dr. Khandwala would receive salary and benefits for a period of six months. On August 24, 1998, we entered into a severance agreement with Dr. Khandwala in connection with his resignation as Senior Vice President, Development and Chief Regulatory Officer on October 2, 1998. Under this agreement, we will continue to forgive the remaining balance of his loan over the remaining two and one half years of the loan term, provided that Dr. Khandwala continues to provide consulting services to us. On October 28, 1998, we entered into an agreement with Dr. Khandwala pursuant to which he rendered consulting services to us through April 2, 1999. In connection with this agreement, we issued to Dr. Khandwala 4,366 shares of common stock and loaned him the funds necessary to satisfy the federal and state withholding taxes applicable to those shares. In addition, we granted Dr. Khandwala an option to purchase 2,000 shares of common stock at an exercise price of $28.75, the fair market value of our common stock on October 20, 1998. The option will become exercisable in six successive equal monthly installments on the last day of each month during the consulting period. None of our other executive officers have employment agreements with us, and their employment may be terminated at any time at the discretion of the board of directors. As administrator of the 1992 Stock Option Plan, the compensation committee has the authority to provide for accelerated vesting of the shares of common stock subject to any outstanding options held by the Chief Executive Officer and our other executive officers or any unvested shares actually held by those individuals under the 1992 Stock Option Plan upon a change in control of Shaman effected through a successful tender offer for more than 50% of our outstanding voting securities or through a change in the majority of the board as a result of one or more contested elections for board membership. Indemnification of Directors and Executive Officers and Limitation of Liability Our Restated Certificate of Incorporation and Bylaws provide for indemnification of directors, officers and other agents of Shaman. Each of the current directors and certain officers and agents of Shaman have entered into separate indemnification agreements with us. Certain Relationships and Related Transactions On June 17, 1998, we loaned $300,000 to John W.S. Chow, Ph.D., Vice President, Technical Operations, to reimburse him for a reasonable difference between the purchase price of his residence in the Bay Area and the cost of comparable housing in New Jersey, his former state of residence. The loan is evidenced by his promissory note of the same date which will become due and payable in a series of five successive equal annual installments, with the first such installment due on June 25, 1999. The note will bear interest at a variable per annum rate equal to the short-term applicable federal rate in effect under the federal tax laws for January of each calendar year the loan remains outstanding. Accordingly, the interest rate in effect for the period Dr. Chow's note was outstanding during the 1998 calendar year was 5.52%. Accrued and unpaid interest will become due and payable each year on the same date the principal installment for that year becomes payable. Each installment of principal and accrued interest will automatically be forgiven as that installment becomes due, provided Dr. Chow continues in our employ. However, the entire unpaid balance of the note, together with all accrued and unpaid interest, will become immediately due and payable upon Dr. Chow's termination of employment with us prior to June 25, 2003, unless Dr. Chow's employment is involuntarily terminated by us other than for cause. In the event we terminate Dr. Chow's employment for any reason other than for cause, or Dr. Chow's employment terminates by reason of his death or disability, then the entire principal balance of the note plus accrued interest will be forgiven. The amount outstanding on Dr. Chow's note, including accrued interest, was approximately $313,188 as of March 31, 1999 and the highest amount outstanding on that note during the 1998 fiscal year was $308,729. In April 1999, we entered into a credit facility and note purchase agreement with certain stockholders, key executives and members of the board of directors, pursuant to which we may borrow from such persons approximately $1,000,000 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. As of the date of this prospectus, we have not borrowed any amount under this credit agreement. Certain executive officers and directors who participated in this credit agreement, up to a total of $200,000 include: Lisa A. Conte, Steven R. King, John W.S. Chow, Thomas Carlson, G. Kirk Raab, Adrian D.P. Bellamy, Herbert H. McDade, Jr. and M. David Titus. Any convertible promissory notes issued pursuant to the credit agreement will be due and payable on the earlier of (1) 30 days subsequent to the completion of the public offering, or (2) December 31, 1999, for any amounts that are not converted into 55 Series R Preferred Stock currently being registered. Interest on the convertible promissory notes will accrue at an annual rate of 12%. The convertible promissory notes, if and 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, which is the Series R Preferred Stock, 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 one-third of the five-day weighted average trading price of our common stock for the period ending three trading days prior to conversion or exercise. See "Employment Contracts, Termination Agreements and Change of Control Agreements" and "Director Compensation" with respect to further transactions between us and our officers and directors. 56 PRINCIPAL STOCKHOLDERS The following table sets forth certain information known to us with respect to the beneficial ownership of the common stock as of July 13, 1999 by (1) all persons who are beneficial owners of five percent or more of the common stock, (2) each director, (3) the Named Officers in the Summary Compensation Table above and (4) all current directors and executive officers as a group. The number of shares beneficially owned by each director or executive officer is determined under rules of the SEC and the information is not necessarily indicative of beneficial ownership for any other purpose. Shares of common stock subject to options or warrants currently exercisable or exercisable within 60 days of July 13, 1999 are included in the number of shares beneficially owned by the person holding such option or warrant for computing the percentage ownership of such person, but are not treated as outstanding for computing the percentage of any other person. Except as otherwise indicated, we believe that the beneficial owners of the common stock listed below, based upon such information furnished by such owners, have sole voting and investment power with respect to such shares, subject to community property laws where applicable. The percentages set forth in the percent column under the beneficial ownership after the rights offering heading have been calculated based on the assumption that each stockholder would subscribe for the stockholder's pro-rata portion, determined as of July 13, 1999, of this rights offering, and assuming the conversion of all outstanding Series R Preferred Stock. In the event each stockholder subscribes for the stockholder's pro-rata portion of the rights offering, the stockholders' beneficial ownership percentage of Shaman after the rights offering will not be identical to its beneficial ownership percentage of Shaman prior to the rights offering because SEC regulations require that we include stock options exercisable within 60 days of July 13, 1999, for purposes of the calculations in the table. However, for determining each stockholder's pro-rata portion of the rights offering, we only include the Shaman common stock owned by each stockholder and did not include exercisable or unexercisable options. To the extent any stockholder chooses not to subscribe for its pro-rata portion of the rights offering, its beneficial ownership of Shaman after the rights offering will be less than is indicated in this table. If any stockholder chooses to subscribe for more than its pro-rata portion of the rights offering, its beneficial ownership will be greater than is indicated in this table.

The address of each officer and director identified in this table is that of Shaman's executive offices, 213 East Grand Avenue, South San Francisco, CA 94080. (2) Percentage of beneficial ownership is calculated assuming 3,158,233 shares of common stock were outstanding as of July 13, 1999. Beneficial ownership is determined in accordance with the rules of the Securities and Exchange Commission and generally includes voting or investment power with respect to securities. Shares of common stock subject to options or warrants 57 currently exercisable or convertible, or exercisable or convertible within 60 days of July 13, 1999, are included in the number of shares outstanding for computing the percentage of the person holding such option or warrant but are not included in the number of shares outstanding for computing the percentage of any other person. Except as indicated in the footnotes to this table and pursuant to applicable community property laws, the persons named in the table have sole voting and investment power with respect to all shares of common stock beneficially owned. (3) Does not include 20,000 shares of Series C Preferred Stock which is convertible to a certain number of shares of common stock, such number which shall be determined in accordance with Shaman's certificate of incorporation. (4) Includes 6,372 shares subject to options exercisable within 60 days of July 13, 1999. (5) Includes 9,854 shares subject to options exercisable within 60 days of July 13, 1999. (6) Represents shares subject to options exercisable within 60 days of July 13, 1999. (7) Represents shares subject to options exercisable within 60 days of July 13, 1999. (8) Does not include 1,500 shares of Series C Preferred Stock which is convertible to a certain number of shares of common stock, such number which shall be determined in accordance with Shaman's certificate of incorporation. (9) Total shares held by directors and officers listed above. Also includes 21,275 shares which are currently issuable upon the exercise of outstanding options. 58 DESCRIPTION OF OUR CAPITAL STOCK Our authorized capital stock consists of 220,000,000 shares of common stock, par value $0.001 per share, and 2,000,000 shares of preferred stock, par value $0.001 per share. We have designated 400,000 shares of our preferred stock as Series A Preferred Stock, all of which are issued and outstanding; 200,000 shares as Series C Preferred Stock, 115,958 of which are issued and outstanding; 6,285 shares as Series D Preferred Stock, 1,360 of which are issued and outstanding; and 1,300,000 shares as Series R Preferred Stock, 16,667 of which are issued and outstanding, and up to 1,000,000 shares of which are subject to issuance in this offering and up to 73,112 shares of which are subject to issuance upon exercise of outstanding warrants. Common Stock As of July 13, 1999, there were 3,158,233 shares of common stock outstanding held of record by approximately 966 stockholders, which we believe represents approximately 18,000 beneficial stockholders. The holders of common stock are entitled to one vote per share on all matters to be voted upon by the stockholders. Subject to preferences that may be applicable to outstanding preferred stock, the holders of common stock are entitled to receive ratably such dividends, if any, as may be declared by the board of directors out of funds legally available therefor. See "Dividend Policy." In the event of our liquidation, dissolution, sale or winding up, the holders of common stock are entitled to share ratably in all assets remaining after payment of liabilities, subject to prior distribution rights of preferred stock then outstanding. The common stock has no preemptive or conversion rights or other subscription rights. There are no redemption or sinking fund rights applicable to the common stock. All outstanding shares of common stock are fully paid and nonassessible. Preferred Stock Our board of directors has the authority to issue preferred stock in one or more series and to fix the rights, preferences, privileges and restrictions thereof, including dividend rights, conversion rights, voting rights, terms of redemption, redemption prices, liquidation preferences and the number of shares constituting any series or the designation of such series, without the further vote or action by the holders of common stock. The approval of the outstanding shares of existing series of preferred stock would be required for the issuance of any additional series of preferred stock with rights, preferences or privileges senior to those of the existing series of preferred stock. The issuance of preferred stock may delay, defer, or prevent a change in control of Shaman without further action by the stockholders and may adversely affect the voting and other rights of the holders of common stock. Series A Preferred Stock As of July 13, 1999, there were 400,000 shares of Series A Preferred Stock outstanding held of record by one stockholder. The Series A Preferred will convert into approximately 543,200 shares of common stock on July 23, 1999. Voting. Each holder of Series A Preferred Stock is entitled to that number of votes equal to the number of shares of common stock into which the shares of Series A Preferred Stock held by such stockholder are convertible and has voting rights and powers equal to those of the common stock, except as otherwise expressly provided or as required by law. Dividends. Subject to preferential rights with respect to any series of preferred stock which may from time to time come into existence, holders of Series A Preferred Stock are entitled to receive such dividends as may be declared by the Board of Directors out of funds legally available therefor. Any dividends declared on the Series A Preferred Stock are not cumulative. Liquidation Preference. In the event of a liquidation, dissolution, sale or winding up of Shaman, holders of Series A Preferred Stock are entitled to receive $8.15 per share, as adjusted for any stock dividends, combinations or splits with respect to such shares, plus all accrued or declared but unpaid dividends. If the assets and funds of Shaman legally available for distribution to the holders of the Series A Preferred Stock are insufficient to permit payment of the full preferential amount, then holders of the Series A Preferred Stock are entitled to share ratably the entire amount of such assets or funds legally available for distribution. Conversion. Each share of Series A Preferred Stock is convertible into one share of common stock, as adjusted for any stock dividends, combinations or splits with respect to such shares, at any time at the option of the holder. The minimum number of shares which may be converted at any one time is 75,000 shares, or such lesser number of shares as are then outstanding. Each share of Series A Preferred Stock shall automatically convert into common stock on the 59 earlier to occur of: (1) immediately in the event that at any time prior to July 23, 1999, the closing sale price of our common stock for a period of 60 consecutive trading days exceeded $163.00 per share; or (2) July 23, 1999. If the Series A Preferred Stock is automatically converted on July 23, 1999, the conversion price into common stock is adjusted such that each share of Series A Preferred Stock will automatically convert into such number of shares of common stock as equals $163.00 divided by the weighted-average closing sale price for the 60 consecutive trading days ending two days prior to July 23, 1999, but in no event shall a share of Series A Preferred Stock be convertible into more than 1.358 shares of common stock, in each case as appropriately adjusted for any stock dividends, combinations or splits with respect to such shares of common stock. Redemption. The Series A Preferred Stock is not redeemable. Priority. The Series A Preferred Stock ranks senior to the common stock and the Series R Preferred Stock and junior to the Series C Preferred Stock and the Series D Preferred Stock, if issued, as to dividends, distributions and distribution of assets upon liquidation, dissolution or winding up of Shaman. Series C Preferred Stock As of July 13, 1999, there were 115,958 shares of Series C Preferred Stock outstanding held of record by 21 stockholders. Voting. The holders of the Series C Preferred Stock are entitled during the first year after August 18, 1998, to six votes for each one share of Series C Preferred Stock held; and thereafter, to one vote for each share of common stock into which such share of Series C Preferred Stock is convertible on the record date for the matter to be voted on. Dividends. Each share of Series C Preferred Stock shall be entitled to receive cumulative dividends paid semi-annually on May 30 and November 29 of each year as follows: (1) a stock-on-stock dividend of $10.00 per annum, paid in arrears, in shares of common stock, valued at 85% of the average closing price of the common stock for the 10 trading day period ending three trading days prior to the date on which the dividend is paid; plus (2) a cash amount equaling 0.00005% of Shaman's United States net sales, if any, for the preceding two calendar quarters of its SP-303/Provir product for the treatment of diarrhea less $5.00, which is the value of the semi-annual stock dividend. We have agreed to honor this royalty with our sales of SB-300, to the extent sold to the HIV/AIDS community. If under Delaware law, we are unable to pay the cash amount of the above described dividend, then the cash portion shall be payable in shares of common stock, valued at 85% of the average closing price of the common stock for the 10 day trading period ending three trading days prior to the date on which the dividend is paid. Liquidation Preference. In the event of a liquidation, dissolution, sale or winding up of Shaman, holders of the Series C Preferred Stock shall be entitled to receive, prior and in preference to the holders of the common stock, the Series A Preferred Stock, and the Series D Preferred Stock and the Series R Preferred Stock, an amount equal to $100 per share, plus any accrued and unpaid dividends. Conversion. Each share of Series C Convertible Preferred Stock shall be convertible, at any time commencing on August 18, 1999 at the election of each holder, and automatically on August 18, 2004, into the greater of (1) 0.8333 shares of common stock or (2) such number of shares of common stock as equals $100 divided by 85% of the average closing price of the common stock for the 10 trading day period ending three trading days prior to the date of conversion. Redemption. The Series C Preferred Stock is not redeemable. Priority. The Series C Preferred Stock ranks senior to the common stock, the Series A Preferred Stock, the Series D Preferred Stock and the Series R Preferred Stock as to dividends, distributions and distribution of assets upon liquidation, dissolution or winding up of Shaman. Series D Preferred Stock As of July 13, 1999, there were 1,360 shares of Series D Preferred Stock outstanding held of record by six stockholders. Voting. Except as otherwise required by law or expressly provided in the certificate of incorporation, the Series D Preferred Stock is not entitled to vote on any matter. Dividends. Each share of Series D Preferred Stock shall be entitled to receive cumulative dividends at the rate of $55 per year payable quarterly commencing on February 1, 1999. These dividends may be paid in cash or, subject 60 to certain limitations, any combination of cash and shares of common stock. Dividends not paid on the due date shall accrue interest until paid at the rate of 12% per annum. If the dividend is paid in shares of common stock, the number of shares to be delivered to each holder of Series D Preferred Stock shall be determined by dividing the aggregate dollar amount of the dividend payable to each such holder by an amount equal to 90% of the outstanding price of the common stock during 12 trading days ending one day prior to the date of the conversion. Liquidation Preference. In the event of a liquidation, dissolution, sale or winding up of Shaman, holders of the Series D Preferred Stock shall be entitled to receive, prior and in preference to the holders of the common stock, the Series A Preferred Stock and the Series R Preferred Stock, but subordinate to the holders of the Series C Preferred Stock, an amount equal to $1,000 per share, plus any accrued and unpaid dividends. Conversion. Each share of Series D Convertible Preferred Stock shall be convertible at the election of the holder, at any time commencing on the date on which any shares of Series D Preferred Stock were first issued, into a number of shares of common stock equal to $1,000 plus any accrued but unpaid dividends and interest on the Series D Preferred Stock, divided by 90% of the lowest trading price of the common stock during the 12 trading days ending one day prior to the date of the conversion. The delisting of our common stock from The Nasdaq National Market on February 2, 1999 constituted an Optional Redemption Event, as defined in our Certificate of Incorporation. In connection therewith, on February 4, 1999, we issued a Control Notice, as defined in our Certificate of Incorporation, that prevented the redemption of the Series D Preferred Stock. This Control Notice will remain in effect for as long as we are not listed on any of The Nasdaq National Market, The Nasdaq SmallCap Market, the American Stock Exchange or the New York Stock Exchange. Delivery of the Control Notice had the effect of increasing the annual dividend to $180 per share and adjusting the conversion price of the Series D Preferred Stock to 72% of the lowest trading price during a designated time period prior to the conversion. Redemption. The holders of the Series D Preferred Stock may require that we redeem all or part of their shares if any of the following optional redemption events occur: (1) for five consecutive trading days there is no reported sale price of our common stock on Nasdaq, the New York Stock Exchange or the American Stock Exchange, (2) our common stock ceases to be listed on Nasdaq, the NYSE or the AMEX, (3) we merge or effect another transaction in which we sell all or substantially all of our assets or our stockholders prior to the transaction do not collectively own at least 51% of the voting securities of the surviving corporation, or the common stock of the surviving corporation is not listed on Nasdaq, the NYSE or the AMEX, (4) we adopt changes to our certificate of incorporation that materially and adversely affect the rights of the holders of the Series D Preferred Stock in a different and more adverse manner than they affect the rights of the holders of the common stock, (5) if the holders are unable for a period ranging from 20 to 30 days to sell their shares of common stock issuable upon conversion of the Series D Preferred Stock pursuant to an effective registration statement, or (6) if we fail or default in performing any material obligation to a holder of Series D Preferred Stock under the terms of our certificate of incorporation or the Series D Preferred Stock purchase agreement. The per share redemption price is $1,000 plus 118% of accrued but unpaid dividends on each share of Series D Preferred Stock. We may under certain circumstances issue a control notice upon the occurrence of any of the three optional redemption events described in clauses (1), (2) and (3) above, which will prevent the requirement that we redeem the shares. The issuance of this control notice has the effect of increasing the annual cumulative dividend payable to the Series D Preferred stockholders to $180 per share, if the redemption event was one of those described in clause (1) or (2) above, or $300 per share for the redemption event described in clause (3) above, and adjusting the conversion price of the Series D Preferred Stock to 72% of the lowest trading price for a designated period prior to the conversion, if the redemption event was one of those described in clause (1) or (2) above, or 63% of the lowest trading price for a designated period prior to the conversion, for the redemption event described in clause (3) above. The delisting of our common stock from The Nasdaq National Market in February 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 the control 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. 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 AMEX or the NYSE. Priority. The Series D Preferred Stock ranks senior to the common stock, the Series A Preferred Stock and the Series R Preferred Stock but junior to the Series C Preferred Stock as to dividends, distributions and distributions of assets upon liquidation, dissolution or winding up of Shaman. 61 Series R Preferred Stock Upon completion of this offering, up to 1,016,667 shares of Series R Preferred Stock will be outstanding. The Series R Convertible Preferred Stock will have the following rights, preferences and privileges: Voting. The holders of the Series R Preferred Stock are entitled to 100 votes for each share of Series R Preferred Stock held. Dividends. Subject to preferences that may be applicable to outstanding preferred stock, the holders of Series R Preferred Stock are entitled to receive ratably with the holders of the common stock, such dividends, if any, as may be declared by the board of directors out of funds legally available therefore and will participate with the common stock pro rata on an as-converted to common stock basis, based on a conversion ratio of 150 shares of common stock for each share of Series R Preferred Stock. See "Dividend Policy." Liquidation Preference. In the event of a liquidation, dissolution, sale or winding up of Shaman, holders of the Series R Preferred Stock shall be entitled to receive, prior and in preference to the holders of the common stock, but subordinate to the holders of the Series A, Series C and Series D Preferred Stock, an amount equal to $15.00 per share, plus any accrued and unpaid dividends. Conversion. The Series R Preferred Stock is not convertible until February 1, 2000. On that date, each share of Series R Preferred Stock shall be automatically converted into a number of shares of common stock equal to $15.00 divided by the lower of (1) $0.10, or (2) the per share price that is equal to 10% of the average closing sales price of our common stock for the 10 trading day period ending three trading days prior to February 1, 2000. If on February 1, 2000, as a result of the fluctuating conversion price, we do not have enough shares of common stock authorized under our certificate of incorporation to effect the conversion of all outstanding shares of Series R Preferred Stock and our other series of preferred stock, only the portion of the Series R Preferred Stock, if any, for which there are adequate common stock shares, after taking into account the common stock shares necessary to effect the conversion of any then outstanding shares of Series C Preferred Stock and Series D Preferred Stock, will be converted, allocated pro rata among the holders of the Series R Preferred Stock. The remaining shares of Series R Preferred Stock will remain outstanding until three trading days after an adequate number of common stock shares are authorized to effect the conversion of these shares under our certificate of incorporation. After February 1, 2000, if any shares of Series R Preferred Stock remain outstanding, the conversion price will remain the same as the conversion price in effect on February 1, 2000, subject to adjustments for stock splits, stock dividends and other recapitalizations. If we well all of the shares of Series R Preferred Stock in this offering and if the conversion price of the Series R Preferred Stock is less than $0.10 per share on February 1, 2000, we will need to authorized additional shares of common stock to effect the conversion of all shares of our outstanding preferred stock, which will require stockholder approval. If it appears likely that we will need to authorize more shares of common stock, we anticipate submitting to our stockholders, prior to the conversion date of the Series R Preferred Stock, a proposal to increase the number of shares of common stock we are authorized to issue to a number we believe will be adequate to effect the conversion of all of our preferred stock, including the Series R Preferred Stock. If the stockholders do not approve such an increase in the authorized common stock, all or a portion of the Series R Preferred Stock may not convert on February 1, 2000 and may remain outstanding indefinitely after February 1, 2000 until we can amend our certificate of incorporation to authorize additional shares of common stock to effect this conversion. The delay in conversion of or the indefinite inability to convert all or a portion of the Series R Preferred Stock may decrease the liquidity and the market price of the Series R Preferred Stock. Redemption. The Series R Preferred Stock is not redeemable. Priority. The Series R Preferred Stock ranks equally with the common stock and junior to the Series A, Series C and Series D Preferred Stock as to dividends, and ranks senior to the common stock but junior to the Series A, Series C and Series D Preferred Stock as to distributions of assets upon liquidation, dissolution or winding up of Shaman.

Anti-Takeover Effects of Provisions of Certificate of Incorporation and Bylaws Shaman is subject to the provisions of Section 203 of the Delaware General Corporation Law statute. Section 203 prohibits a publicly held Delaware corporation from engaging in a "business combination" with an "interested stockholder" for a period of three years after the person becomes an interested stockholder, unless the business combination is approved in a prescribed manner. A "business combination" includes mergers, asset sales and other transactions 63 resulting in a financial benefit to the interested stockholder. Subject to certain exceptions, an "interested stockholder" is a person who, together with affiliates and associates, owns, or within three years did own, 15% or more of the corporation's voting stock. Our Certificate of Incorporation divides the board of directors into two classes with staggered two-year terms. Under our by-laws, any vacancy on the board of directors, including a vacancy resulting from an enlargement of the board of directors, may be filled by a majority of the directors then in office. The classification of the board of directors and the limitation on filling of vacancies could make it more difficult for a third party to acquire, or discourage a third party from acquiring, control of Shaman. Transfer Agent and Registrar EquiServe, L.P. is the transfer agent and registrar for our Series R Preferred Stock and common stock. 64 SHARES ELIGIBLE FOR FUTURE SALE Future sales of substantial amounts of common stock in the public market could adversely affect the market price of our common stock. In addition, an active public market for our common stock may not continue in the future.

An additional 21,513,544 shares of common stock will be issuable upon conversion of the Series C Preferred Stock, assuming a conversion price, which is based on the common stock market price as of July 13, 1999, of $0.539 per share, commencing on August 18, 1999, all of which will be freely tradable without restriction. We will also have up to 1,016,667 shares of Series R Preferred Stock outstanding and 73,112 shares of Series R Preferred Stock subject to issuance upon exercise of outstanding warrants. The Series R Preferred Stock is convertible into common stock on February 1, 2000. On that date, each share of Series R Preferred Stock will automatically convert into a number of shares of common stock equal to $15.00 divided by the lower of (1) $0.10, or (2) a per share price that is equal to 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. Assuming a conversion price of $0.10 per share, upon conversion of the Series R Preferred Stock on February 1, 2000, 163,466,900 shares of common stock will be issued, or issuable pursuant to warrants, that will be immediately freely tradable without restriction, other than by our affiliates. 65 THE RIGHTS OFFERING The Subscription Rights We are offering our stockholders the right to subscribe for and purchase up to 1,000,000 shares of Series R Convertible Preferred Stock at $15.00 per share. The rights offering is open only to those stockholders who owned common stock on July 14, 1999. The rights offering is not open to anyone who did not own common stock on July 14, 1999. We are offering stockholders the opportunity to purchase seven shares of Series R Preferred Stock for each 22.11 shares of common stock they owned on July 14, 1999. In determining the number of shares of Series R Convertible Preferred Stock we will issue to each stockholder pursuant to the subscription rights offered by this prospectus, we will round up to the nearest whole number. We will not issue subscription rights to purchase fractional shares and we will not pay cash in place of subscription rights. The subscription rights are not transferable and will not be listed for trading on any stock exchange. The Series R Preferred Stock will be quoted on the OTC Bulletin Board under the symbol "SHMNO" and we expect that these shares will trade prior to their conversion to common stock on February 1, 2000. Basic Subscription Privilege Each subscription right entitles you to purchase seven shares of Series R Preferred Stock for each 22.11 shares of common stock you owned at the close of business on July 14, 1999. You must purchase a minimum of seven shares of Series R Preferred Stock to participate, and if you hold fewer than 22.11 shares of common stock on the record date, you will be allowed to purchase seven shares of Series R Preferred Stock. You will receive certificates representing the shares that you purchase pursuant to your basic subscription privilege as soon as practicable after your basic subscription has been accepted, which may occur at any time prior to the expiration of this offering. We may accept your basic subscription amount prior to accepting your over-subscription amount. In that event, we will deliver stock certificates for the basic subscription amount and the subscription agent will retain the over-subscription amount in escrow until the expiration of this offering, as provided below. Over-Subscription Privilege Each subscription right also grants you an over-subscription privilege to purchase additional shares of Series R Preferred Stock that are not purchased by other stockholders. You are entitled to exercise your over-subscription privilege only if you exercise your basic subscription privilege in full. If you wish to exercise your over-subscription privilege, you should indicate the number of additional shares that you would like to purchase in the space provided on your subscription agreement. When you send in your subscription agreement, you must also send the full purchase price for the number of additional shares that you have requested to purchase in addition to the payment due for shares purchased through your basic subscription privilege. If the number of shares remaining after the exercise of all basic subscription privileges is not sufficient to satisfy all over-subscription privileges, you will be allocated shares pro rata, subject to elimination of fractional shares, in proportion to the number of shares you offer to purchase above your basic subscription privilege. However, if your pro rata allocation exceeds the number of shares you requested on your subscription certificate, then you will receive only the number of shares that you requested, and the remaining shares from your pro rata allocation will be divided among other stockholders exercising their over-subscription privileges. In addition, we have the discretion to issue less than the total number of shares that may be available for over-subscription requests. As soon as practicable after August 23, 1999, or September 7, 1999, if Shaman extends the offering to such date, EquiServe, L.P., the subscription agent, will determine the number of shares of Series R Preferred Stock that you may purchase pursuant to the over-subscription privilege. You will receive certificates representing these shares as soon as practicable after the expiration date. If you request and pay for more shares than are allocated to you, we will refund that overpayment to you, without interest. In connection with the exercise of the over-subscription privilege, banks, brokers and other nominee holders of subscription rights who act on behalf of beneficial owners will be required to certify to the subscription agent and us as to the aggregate number of subscription rights that have been exercised, and the number of shares of Series R Preferred Stock that are being requested through the over-subscription privilege, by each beneficial owner on whose behalf such nominee holder is acting. Minimum Subscription Requirement We require a minimum subscription of seven shares of Series R Preferred Stock, or $105. This means that if you hold fewer than 22.11 shares of common stock on the record date, you may purchase seven shares of Series R Preferred Stock, which will constitute your basic subscription privilege. 66 Plan of Distribution On or about July 20, 1999, we will distribute the subscription rights agreements and copies of this prospectus to individuals who owned shares of our common stock on July 14, 1999. If you wish to exercise your subscription rights and purchase shares of Series R Preferred Stock, you should complete the subscription agreement and return it, with payment for the shares, to the subscription agent, EquiServe, L.P. If you have any questions, you should contact our information agent, Shareholder Communications Corporation, at the telephone number and address on page 65. See "The Rights Offering -- Subscription Procedures." We have retained our transfer agent, EquiServe, L.P., to assist with the rights offering in the role of the subscription agent. The subscription agent will hold all subscription agreements received from stockholders, and will be responsible for delivering stock certificates and refunds, in case of over-subscription or cancellation of the offering, to stockholders. We will pay all fees and expenses of the subscription agent in connection with the rights offering, which we estimate will be approximately $15,000. You are responsible for paying any other commissions, fees, taxes or other expenses incurred in connection with the exercise of the subscription rights. Expiration Date The rights offering will expire at 5:00 p.m., Eastern Daylight Savings Time, on August 23, 1999, unless extended in the sole discretion of Shaman until September 7, 1999. If you do not exercise your basic subscription privilege or over-subscription privilege prior to such time, we have the right to reject your subscription. We reserve the right to reject any subscription agreements that the subscription agent receives after 5:00 p.m. on the expiration date, regardless of when the documents were originally mailed. Stockholders who wish to participate in the rights offering should submit all subscription agreements to EquiServe, L.P. by the expiration date, or to their broker or bank at least 10 days before the expiration date, to allow the broker or bank sufficient time to carry out those instructions. The rights offering is not conditioned upon our receipt of subscriptions for any minimum number of shares. However, the rights offering may be cancelled at any time prior to its completion, in which case all subscription payments will be returned without interest. Subscription Payments Each subscription agreement submitted pursuant to this rights offering must be accompanied by the full amount of the purchase price for all of the shares of Series R Preferred Stock subscribed for by the stockholder. If a stockholder submits less than the full purchase price, we will limit such stockholder's maximum subscription to the number of shares purchasable with those funds, rounded down to the nearest whole number of shares. If a subscription is rejected in whole or in part, the subscription agent will promptly refund payment for any unpurchased shares. We will not pay interest on any subscription funds. Determination of Offering Price We have obtained an opinion from Alliant Partners that the terms of this rights offering are fair, from a financial point of view, to our stockholders. The price at which the Series R Preferred Stock will convert into common stock was set at a substantial discount to the actual trading price of our common stock. This discount is offered as an incentive for our current stockholders to participate in this offering. Nevertheless, the offering price does not necessarily bear any relationship to the book value of our assets, past operations, cash flow, earnings, financial condition or any other established criteria for value and should not be considered an indication of our underlying value. 67 Subscription Procedures To participate in the rights offering, you must submit a properly completed subscription agreement, together with full payment of the offering price for all shares for which you subscribe. Those who hold common stock for the account of others, such as brokers, banks, trustees or depositories, should notify the beneficial owners of those shares as soon as possible to ascertain the beneficial owners' intentions and to obtain instructions with respect to the rights offering. The subscription agreement and payment must be received by the subscription agent before 5:00 p.m., Eastern Daylight Savings Time, on August 23, 1999, unless extended in our sole discretion until September 7, 1999. Payment of the offering price must be made: - by check or bank draft drawn upon a U.S. bank or postal, telegraphic, or express money order payable to "EquiServe, L.P., as Subscription Agent;" or - by notice of guaranteed delivery of payment from a bank, a trust company or a New York Stock Exchange member. Payment of the offering price will be considered made only upon (1) the subscription agent's receipt of a certified check or bank draft drawn upon a U.S. bank or any postal, telegraphic or express money order or (2) the clearance of any uncertified check. If you wish to pay by uncertified personal check, please note that your check may take five business days or more to clear and, therefore, you should make payment sufficiently in advance of the expiration date to ensure that payment is received and cleared by the expiration date. Subscription agreements and any checks in payment of the offering price should be delivered by mail, hand delivery, or overnight courier, to the applicable address below: By Mail By Hand By Overnight Carrier ------- ------- -------------------- Securities Transfer & EquiServe, L.P.

Box 9573 100 Williams Street, Galleria 40 Campanelli Drive Boston, MA 02205-9573 New York, NY 10038 Braintree, MA 02184 If you do not indicate the number of shares to be purchased or do not forward full payment of the offering price, then your payment will be credited to purchase your basic subscription privilege to the full extent of the payment received and, if any funds remain, will be credited to purchase your over-subscription privilege to the extent of the remaining funds. In each case, share amounts will be rounded down to the nearest whole number. The method of delivery of the subscription agreement and payment of the offering price will be at your election and risk. If sent by mail, it is recommended that your subscription agreement and payment be sent by registered mail, properly insured, with return receipt requested, and that a sufficient number of days be allowed to ensure delivery to the subscription agent and clearance of payment prior to the expiration date. Because uncertified personal checks may take at least five business days to clear, you are urged to arrange for payment by certified or cashier's check, money order or wire transfer of funds. Our answers to all questions concerning the timeliness, validity, form and eligibility of any subscription will be final and binding. We may, in our sole discretion, waive any defect or irregularity, permit a defect or irregularity to be corrected within any time as we may determine, or reject the purported exercise of any right. Subscriptions will not be considered to have been received or accepted until all irregularities have been waived or cured within the time that we determine in our discretion. Neither we nor the subscription agent will be under any duty to notify you of any defect or irregularity in connection with the submission of your subscription agreement or incur any liability for failure to give notification. If you have any questions concerning the rights offering or these subscription procedures, or if you would like additional copies of this prospectus or other documents, please contact our information agent: Shareholder Communications Corporation, 17 State Street, New York, NY 10004. Banks and brokers may call the information agent at (212) 805-7113, and stockholders may call toll free at (800) 546-8622. 68 Non-Transferability of Subscription Rights Only you may exercise the basic subscription privilege and the over-subscription privilege. You may not sell, give away or otherwise transfer the basic subscription privilege or the over-subscription privilege. No Revocation of Subscription After you have exercised your basic subscription privilege or over-subscription privilege, you may not revoke that exercise. You should not exercise your subscription rights unless you are certain that you wish to purchase shares of our Series R Convertible Preferred Stock. Amendment and Termination of Rights Offering We reserve the right to amend the terms and conditions of the rights offering. If we make an amendment that we consider significant, we will (1) mail notice of the amendment to all stockholders who owned shares of common stock on July 14, 1999, (2) extend the expiration date by at least 14 days and (3) offer all subscribers not less than 10 days to revoke any prior subscriptions, in whole or in part. In all other cases, subscriptions will be irrevocable. We also reserve the right to terminate the rights offering at any time, in our discretion, in which case all subscriptions will be cancelled, and we will return all subscription payments to subscribers without interest. Upon the occurrence of any change in or cancellation of the rights offering, we will issue a press release to that effect, and we will file a post-effective amendment to the registration statement covering this prospectus. Shares of Common Stock Outstanding After the Rights Offering Assuming we issue all of the shares of Series R Preferred Stock offered in the rights offering and assuming conversion of all of such shares at a conversion price of $0.10 per share, approximately 150,000,000 shares of common stock will be issued and outstanding following the rights offering and conversion of the Series R Preferred Stock. This would represent a 98% increase in the number of outstanding shares of our common stock. If you do not exercise your basic subscription privilege, the percentage of Shaman common stock that you hold will substantially decrease. Certain Ownership Limits and Reporting Requirements Any person or group that acquires direct or indirect beneficial ownership of more than 5% of the outstanding shares of our common stock will be subject to special reporting requirements under Section 13(d) or 13(g) of the Securities Exchange Act of 1934. Any person or group that acquires direct or indirect beneficial ownership of more than 10% of the outstanding shares of our common stock will be subject to special reporting requirements under Section 16(a) of the Exchange Act and may become liable under Section 16(b) of the Exchange Act for reimbursement of any "short-swing profits." Please consult with your attorney to see if these rules will apply to you. State and Foreign Securities Laws The rights offering is not being made in any state or foreign country in which it is unlawful to do so, nor are we selling or accepting subscriptions from holders who are residents of any such state or country. We may delay the commencement of the rights offering in certain states or other jurisdictions in order to comply with the securities law requirements of those states or other jurisdictions. It is not anticipated that there will be any changes in the terms of the rights offering. We may decline, in our sole discretion, to make modifications to the terms of the rights offering requested by certain states or other jurisdictions, in which case stockholders who live in those states or jurisdictions will not be eligible to participate in the rights offering. No Recommendations We are not making any recommendation as to whether or not you should exercise your subscription rights. You should make your decision based on your own assessment of your best interests. 69 FEDERAL INCOME TAX CONSIDERATIONS The following summarizes the material federal income tax consequences of the rights offering. This summary is based on current law, which is subject to change at any time, possibly with retroactive effect. This summary is not a complete discussion of all federal income tax consequences of the rights offering, and, in particular, may not address federal income tax consequences applicable to stockholders subject to special treatment under federal income tax law. In addition, this summary does not address the tax consequences of the rights offering under applicable state, local or foreign tax laws. This discussion assumes that your shares of Shaman stock and the subscription rights and shares issued to you pursuant to the rights offering constitute capital assets. Receipt and exercise of the subscription rights distributed pursuant to the rights offering is intended to be nontaxable to stockholders, and the following summary assumes you will qualify for such nontaxable treatment. We have not sought, nor do we intend to seek, any ruling from the IRS or an opinion of counsel related to the tax matters described below. This discussion is included for your general information only. You should consult your tax advisor to determine the tax consequences to you of the rights offering in light of your particular circumstances, including any state, local and foreign tax consequences. Taxation of Stockholders Receipt of a subscription right: You will not recognize any gain or other income upon receipt of a subscription right. Tax basis of subscription rights: Your tax basis in each subscription right will depend on whether you exercise the subscription right or allow the subscription right to expire. If you exercise a subscription right, your tax basis in the subscription right will be determined by allocating the tax basis of your Shaman stock on which the subscription right is distributed between the Shaman stock and the subscription right, in proportion to their relative fair market values on the date of distribution of the subscription right. However, if the fair market value of your subscription rights is less than 15% of the fair market value of your existing shares of Shaman stock, then the tax basis of each subscription right will be zero, unless you elect, by attaching an election statement to your federal income tax return for 1999, to allocate tax basis to your subscription rights. If you allow a subscription right to expire, it will be treated as having no tax basis. Holding period of subscription rights: Your holding period for a subscription right will include your holding period for the shares of common stock upon which the subscription right is issued. Expiration of subscription rights: You will not recognize any loss upon the expiration of a subscription right. Exercise of subscription rights: You generally will not recognize a gain or loss on the exercise of a subscription right. The tax basis of any share of Series R Preferred Stock that you purchase through the rights offering will be equal to the sum of your tax basis, if any, in the subscription right exercised and the price paid for the share. The holding period of the shares of Series R Preferred Stock purchased through the rights offering will begin on the date that you exercise your subscription rights. If treated as a taxable distribution: If, contrary to Shaman's intent, the rights offering does not qualify as nontaxable, you would be treated as receiving a taxable distribution equal to the fair market value of the subscription rights on their distribution date. The distribution would be taxed as a dividend to the extent made out of our current or accumulated earnings and profits; and any excess would be treated first as a return of your basis (investment) in your Shaman stock and then as a capital gain. You would have a tax basis in the rights equal to the fair market value of the rights on the date of the rights distribution and your holding period in the rights would begin on the date of distribution of the rights. Expiration of the subscription rights would result in a capital loss. You generally will not recognize gain or loss on the exercise of a subscription right. The tax basis of any share of common stock that you purchase through the rights offering will be equal to the sum of your tax basis, if any, in the subscription right exercised and the price paid for the share. The holding period of the shares of common stock purchased through the rights offering will begin on the date that you exercise your subscription rights. Conversion of Series R Preferred Stock to Common Stock: There is some risk that the Internal Revenue Service would argue that the conversion of the Series R Preferred Stock to common stock is properly characterized as a taxable stock dividend rather than a nontaxable event. If the conversion were treated as a taxable stock dividend, the Internal Revenue Service may argue that the amount 70 of the dividend is equal to the amount of the discount from the stated trading price of the common stock on which the conversion is based. Because the Series R Preferred Stock will convert automatically and in the full to common stock, and because the Series R Preferred Stock will not have any declared and unpaid dividends as of the time the conversion occurs, Shaman anticipates that the conversion of the Series R Preferred Stock will qualify as a nontaxable event. If the conversion qualifies as a nontaxable event, your tax basis in your Series R Preferred Stock will be allocated among the shares of common stock you receive upon conversion, and the holding period of the shares of common stock will include your holding period you had in the Series R Preferred Stock prior to conversion. Taxation of Shaman We will not recognize any gain, other income or loss upon the issuance of the subscription rights, the lapse of the subscription rights, or the receipt of payment for shares of Series R Preferred Stock upon exercise of the subscription rights. LEGAL MATTERS Brobeck, Phleger & Harrison LLP will deliver an opinion to us about the validity of the issuance of the shares of our Series R Preferred Stock. EXPERTS Ernst & Young LLP, independent auditors, have audited our financial statements at December 31, 1998 and 1997 and for each of the three years in the period ended December 31, 1998, as set forth in their report, which contains an explanatory paragraph describing conditions that raise substantial doubt about our ability to continue as a going concern as described in Note 1 to the financial statements. We've included our financial statements in this prospectus and in the registration statement in reliance on Ernst & Young LLP's report, given on their authority as experts in accounting and auditing. 71 SHAMAN PHARMACEUTICALS, INC INDEX TO FINANCIAL STATEMENTS Report of Independent Auditors..............................................F-2 Balance Sheets as of December 31, 1997 and 1998 and March 31, 1999 (unaudited)...............................................................F-3 Statements of Operations for the years ended December 31, 1996, 1997, and 1998 and the three months ended March 31, 1998 and 1999 (unaudited)...F-4 Statements of Stockholders' Equity for the years ended December 31, 1996, 1997, 1998 and the three months ended March 31, 1999 (unaudited)..........F-5 Statements of Cash Flows for the years ended December 31, 1996, 1997, 1998 and the three months ended March 31, 1998 and 1999 (unaudited).......F-7 Notes to Financial Statements...............................................F-8 F-1 REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS The Board of Directors and Stockholders of Shaman Pharmaceuticals, Inc. We have audited the accompanying balance sheets of Shaman Pharmaceuticals, Inc. as of December 31, 1998 and 1997, and the related statements of operations, stockholders' equity, and cash flows for each of the three years in the period ended December 31, 1998. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Shaman Pharmaceuticals, Inc. at December 31, 1998 and 1997, and the results of our operations and our cash flows for each of the three years in the period ended December 31, 1998, in conformity with generally accepted accounting principles. The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As more fully described in Note 1, the Company had cash, cash equivalents and short-term investments at December 31, 1998 aggregating $9.2 million which are not sufficient to enable the Company to pay its existing liabilities and to fund its operations through December 31, 1999. The Company has incurred recurring operating losses and has total liabilities at December 31, 1998 in excess of its available cash resources. These conditions raise substantial doubt about the Company's ability to continue as a going concern. Management's plans in regard to these matters are also described in Note 1. The financial statements referred to above do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classification of liabilities that may result from the outcome of this uncertainty.

F-7 SHAMAN PHARMACEUTICALS, INC. NOTES TO FINANCIAL STATEMENTS (information pertaining to the periods ended March 31, 1998 and 1999 is unaudited) 1. Summary of Significant Accounting Policies General To date, Shaman Pharmaceuticals has been primarily focused on discovering and developing novel pharmaceutical products for major human diseases by isolating and optimizing active compounds found in tropical plants with a history of medicinal use. We have conducted human clinical trials with our three lead product candidates -- SP-303/Provir (Phase III/II), nikkomycin Z (Phase I) and SP-134101 (Phase I) -- targeting five indications. Due to unforeseen delays and costs necessary to complete additional necessary trials for our lead compound, SP-303/Provir for the treatment of diarrhea in people with AIDS, we have chosen to discontinue all pharmaceutical development, manufacturing and marketing activities. We intend to sell or out-license worldwide marketing rights to our pharmaceutical assets. We plan to focus our efforts on our Botanicals division. Matters Affecting Ongoing Operations The accompanying financial statements have been prepared assuming that we will continue as a going concern. We have cash, cash equivalents and short-term investments at December 31, 1998 aggregating $9.2 million which are not sufficient to enable us to pay existing liabilities and fund our operations through December 31, 1999. We have total liabilities in excess of our available cash resources at December 31, 1998. We have had recurring net losses, including a net loss applicable to common stockholders of $38.5 million in the year ended December 31, 1998, and have an accumulated deficit of $150.4 million at December 31, 1998. These conditions raise substantial doubt about our ability to continue as a going concern. To address these matters, on February 1, 1999, we announced and initiated the implementation of a Restructuring Plan which resulted in the immediate cessation of all pharmaceutical research and development activities, a reduction in workforce of 60 employees, and will result in the closing down of all of the operations of our pharmaceutical business (see Note 2). After the implementation of the Restructuring Plan, we expect our cash resources available at December 31, 1998 to be substantially used before the end of June 1999. Further, we intend to sell or enter into outlicensing agreements with respect to all of our current pharmaceutical research programs including SP-303/Provir, nikkomycin Z and SP-134101. We are currently negotiating for the termination of our remaining research and development collaboration agreement with Lipha S.A., a wholly-owned subsidiary of Merck KGaA, Darmstadt, Germany. We intend to focus our future efforts on the development and commercialization of botanical dietary supplements derived from tropical plant sources. Revenue Recognition Revenue under our collaborative research agreements is recognized ratably as costs are incurred by us in accordance with the performance requirements of the agreements. Non-refundable payments that are not dependent on future performance under collaborative agreements are recognized as revenue when received. Payments received which are still subject to future performance requirements are deferred until earned. Revenues from achievement of milestone events are recognized when the funding party agrees that the scientific or clinical results stipulated in the agreement have been met. Costs of contract revenue approximate such revenue and are included in research and development expenses. Research and Development Expense Research and development expense consists of independent research and development costs and the costs associated with work performed under collaborations. Research and development costs include direct and research-related overhead expenses and are expensed as incurred. F-8 Stock-Based Compensation In October 1995, the Financial Accounting Standards Board ("FASB") issued Statement of Financial Accounting Standards, "Accounting for Stock-Based Compensation" ("SFAS 123") which encourages, but does not require, companies to record compensation expense for stock-based employee compensation plans at fair value. We have elected to follow the disclosure requirements of SFAS 123 for the year ended December 31, 1998, 1997 and 1996 and will continue to measure stock-based compensation to employees in accordance with APB Opinion No. 25, "Accounting for Stock Issued to Employees." Note 8 contains a summary of the pro forma effects to reported net loss applicable to common stockholders and net loss per common share for 1996, 1997 and 1998 as if we had elected to recognize compensation expense based on the fair value of options granted as described by SFAS 123. We grant stock options to employees and directors for a fixed number of shares with an exercise price equal to the fair market value of shares at the date of grant. We account for stock option grants to employees and directors in accordance with APB Opinion No. 25, Accounting for Stock Issued to Employees and, accordingly, recognize no compensation expense for the stock option grants to employees and directors. Per Share Data Net loss per share is computed using the weighted average number of shares of common stock outstanding. The impact of stock options and other common stock equivalents have been excluded from the computation in all years presented as they are antidilutive. Comprehensive Loss As of January 1, 1998, we adopted Financial Accounting Standards Board ("FASB") Statement No. 130, Reporting Comprehensive Income ("SFAS 130"). SFAS 130 established new rules for the reporting and displaying of comprehensive income and its components; however, the adoption of this statement had no impact on our net loss or total stockholders' equity. SFAS 130 requires unrealized gains or losses on our available for sale securities, which prior to adoption were reported in stockholder's equity, to be included in other comprehensive income (loss). Our comprehensive loss was not materially different from our net loss applicable to common stockholders in 1996, 1997 and 1998. Cash, Cash Equivalents, Investments and Concentration of Credit Risk We consider all highly liquid investments with remaining maturities of three months or less at time of purchase to be cash equivalents. Investments with maturities of less than one year from the balance sheet date and with original maturities greater than 90 days are considered short-term investments. Investments with maturities greater than one year from the balance sheet date are considered long-term investments. Investments consist primarily of commercial paper, investments in government securities, corporate bonds and asset-backed securities. These investments typically bear minimal risk. This diversification of risk is consistent with our policy to maintain high liquidity and ensure safety of principal. We maintain our cash, cash equivalents and investments in accounts with several United States banks and brokerage houses. We determine the appropriate classification of debt securities at the time of purchase and re-evaluate such determination as of each balance sheet date. As of December 31, 1997 and 1998, we have classified our entire investment portfolio as available-for-sale. Available-for-sale securities are carried at fair value, with the unrealized gains and losses, net of tax, included in other comprehensive income. The amortized cost of debt securities in this category is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization is included in interest income. Realized gains and losses and declines in value judged to be other-than-temporary on available-for-sale securities are included in interest income or expense. The cost of securities sold is based on the specific identification method. Interest and dividends on securities classified as available-for-sale are included in interest income. Property and Equipment Property and equipment are stated at cost. Depreciation of equipment and furniture is provided on a straight-line basis over the estimated useful lives of the respective assets, which range from three (computer equipment and furniture) to five (laboratory equipment) years. Equipment held under capital leases is amortized using the straight-line method over the shorter of the lease term or estimated useful life of the asset. Leasehold improvements are amortized on a straight-line basis over the remaining life of the lease. F-9 Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Carrying Value of Long-Lived Assets and Long-Lived Assets to be Disposed Of In accordance with Financial Accounting Standards Board Statement No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long Lived Assets to be Disposed Of," we record impairment losses on long-lived assets when events and circumstances indicate that the assets might be impaired and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amounts of those assets. Based on our estimate of future undiscounted cash flows, except for a reserve included in the estimated restructuring charge (see Note 2), we expect to recover the carrying amounts of our long-lived assets. Nonetheless, it is reasonably possible that the estimate of undiscounted cash flows may change in the near term resulting in the need to write-down those assets to fair value. Segment Reporting In June 1997, the FASB issued SFAS No. 131, Disclosures about Segments of an Enterprise and Related Information ("FAS131"). SFAS 131 establishes standards for the way that public business enterprises report information about operating segments in annual financial statements and requires that those enterprises report selected information about operating segments in interim financial reports. It also establishes standards for related disclosures about products and services, geographic areas, and major customers. We have determined that in 1996, 1997 and 1998, we operated in only one segment. Unaudited Interim Financial Statements The unaudited interim financial statements include all adjustments, consisting only of normal recurring accruals, which the Company considers necessary for a fair presentation of the financial position of the Company as of March 31, 1999 and the results of operations and statement of cash flows of the three months ended March 31, 1998 and 1999, as presented in the accompanying unaudited interim financial statements. Reclassification Certain prior year amounts have been reclassified to conform to the current year's presentation. 2. Restructuring Plan On February 1, 1999, we announced and initiated implementation of a restructuring plan which resulted in the closing down of 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 through our botanicals division. The restructuring plan includes: cessation of pharmaceutical research and development activities and related operations; sale or outlicensing of all of our current pharmaceutical research programs; reduction in force of approximately 60 employees (65% of our workforce); dedication of initially 12 employees (as of February 26, 1999, 5 employees remain) to the process of closing down the pharmaceutical business; termination of the research and development contract with Lipha/Merck; settlement of outstanding long-term equipment financing obligations; sale or disposal of all of our fixed assets that are not needed for our botanicals business; and sub-lease a portion of the facility. The termination of 60 employees occurred on February 1, 1999. We recorded total costs of the restructuring in the first quarter of 1999 of $2.2 million. 3. Collaborative Relationships In September 1996, we entered into a five-year collaborative agreement with Lipha/Merck to jointly develop Shaman's antihyperglycemic drugs. Upon signing the collaboration, we received an annual research fee of $1.5 million which was amortized to revenue over twelve months as the work was performed. We also received approximately $3 million for 19,446 shares of common stock priced at $154.20 per share, representing a 20% premium to the weighted average price of the common stock at the time of purchase. In exchange for development and marketing rights in all countries except Japan, South Korea, and Taiwan (which F-10 are covered under an earlier agreement between Shaman and Ono Pharmaceutical Co. Ltd. Osaka, Japan ("Ono"), Lipha/Merck agreed to provide up to $9.0 million in research payments and up to $10.5 million in equity investments priced at a 20% premium to a multi-day volume weighted average price of common stock at the time of purchase. The research payments were recognized as revenue ratably as the related costs were incurred by us in the performance of our obligations to perform certain research and clinical trial activities. The agreement also provided for additional preclinical and clinical milestone payments to us in excess of $10.0 million per compound for each antihyperglycemic drug developed and commercialized. Lipha/Merck agreed to bear all pre-clinical, clinical, regulatory and other development expenses associated with the compounds selected under the agreement. Preclinical and clinical milestone payments would be recognized as revenue as certain preclinical hurdles were met and as certain phases of the clinical trials and the FDA approval process were completed. In addition, as products were commercialized, Shaman would receive royalties on all product sales outside the United States and up to 50% of the profits (if we exercise our co-promotion rights) or royalties on all product sales in the United States. Certain of the milestone payments would be credited against future royalty payments, if any, due to us from sales of products developed pursuant to the agreement. 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. For the year ended December 31, 1998, Shaman recognized $1.9 million in revenue from the Lipha/Merck collaboration. In addition, we received a total $2.5 million for issuance of 57,762 shares of common stock (40,650 shares priced at $37.00 per share in September 1998 and 17,112 shares priced at $58.40 per share in December 1998), each representing a 20% premium to the weighted average price of common stock at the time of purchase. Revenues from Lipha/Merck accounted for 12%, 43% and 70% of total revenues earned in 1996, 1997 and 1998 respectively. On February 1, 1999, we discontinued all research and development activities related to the collaborative agreement. We are currently in negotiations with Lipha/Merck, for the discontinuation of this research agreement. There will be no further research payments from Lipha/Merck. In May 1995, we entered into a collaborative agreement with Ono providing for, among other things, three years of funding for the research and development of compounds for the treatment of Type II diabetes. Under the agreement, Shaman was obligated to screen 100 diabetes-specific plants per year in vivo, isolate and identify active compounds, and participate in any medicinal chemistry modification. In turn, Ono provided us with access to Ono's preclinical and clinical development capabilities through proprietary in vitro assays and medicinal chemistry effort. Ono's development and commercialization rights are for the countries of Japan, South Korea and Taiwan. Under the terms of the agreement, Ono provided $7.0 million in collaborative research funding and will pay preclinical and clinical milestone payments of $4.0 million per compound for each antidiabetic drug that is commercialized. We received an additional $1.0 million payment (beyond the $7.0 million commitment) in December 1996 for enhanced access rights to these compounds. For the years ended December 31, 1996, 1997 and 1998, Shaman recognized $3.0 million, $2.0 million and $790,000, respectively in revenue from the Ono collaboration. Revenues from Ono accounted for 88%, 57% and 30% of total revenues earned in 1996, 1997 and 1998, respectively. In May 1998, our collaborative agreement with Ono, and the ongoing research and development funding received pursuant thereto, expired under the original terms thereof and was not renewed. Under the agreement, Ono will continue to provide milestone payments and royalties to us on any resulting products Ono develops from compounds identified during the three-year term of the agreement. Costs associated with revenue from these collaborations totaled $11.6 million, $11.4 million and $8.2 million for the year ended December 31, 1996, 1997 and 1998, respectively, and are included in research and development expenses in the accompanying financial statements. F-11 4. Investments The following is a summary of available-for-sale securities (in thousands): December 31, 1997 -------------------------------------------- Gross Gross Estimated Unrealized Unrealized Fair Cost Gains Losses Value ------- ---------- ---------- ---------- U.S. Treasury securities and government obligations $ 4,625 $ -- $ (10) $ 4,615 U.S. corporate bonds 3,000 -- -- 3,000 U.S. corporate commercial paper and other 10,810 -- (20) 10,790 ------- -------- -------- -------- Total $18,435 $ -- $ (30) $18,405 ======= ======== ======== ======== Above amounts are included in the balance sheet as follows: Cash and cash equivalents $ 8,345 -- $ (20) $ 8,325 Short-term investments 10,090 -- (10) 10,080 ------- -------- -------- -------- Total $18,435 $ -- $ (30) $18,405 ======= ======== ======== ======== December 31, 1998 -------------------------------------------- Gross Gross Estimated Unrealized Unrealized Fair Cost Gains Losses Value ------- ---------- ---------- ---------- U.S. Treasury securities and government obligations $ 2,255 $ -- $ (5) $ 2,250 U.S. corporate bonds 1,000 -- -- 1,000 U.S. corporate commercial paper and other 4,984 -- (10) 4,974 ------- -------- -------- -------- Total $ 8,239 $ -- $ (15) $ 8,224 ======= ======== ======== ======== Above amounts are included in the balance sheet as follows: Cash and cash equivalents $ 4,957 -- $ (10) $ 4,947 Short-term investments 3,282 -- (5) 3,277 ------- -------- -------- -------- Total $ 8,239 $ -- $ (15) $ 8,224 ======= ======== ======== ======== March 31, 1999 -------------------------------------------- Gross Gross Estimated Unrealized Unrealized Fair Cost Gains Losses Value ------- ---------- ---------- ---------- U.S. Treasury securities and government obligations $ 1,004 $ -- $ - $ 1,004 U.S. corporate commercial paper and other 644 -- - 644 ------- -------- -------- -------- Total $ 1,648 $ -- $ - $ 1,648 ======= ======== ======== ======== Above amounts are included in the balance sheet as follows: Cash and cash equivalents $ 644 -- $ - $ 644 Short-term investments 1,004 -- - 1,004 ------- -------- -------- -------- Total $ 1,648 $ -- $ - $ 1,648 ======= ======== ======== ======== F-12 The average remaining maturity of the portfolio was approximately four and one-half months at December 31, 1997 and approximately less than one month as of December 31, 1998, respectively. The estimated fair value amounts have been determined by us using available market information and appropriate valuation methodologies. However, judgment is required in interpreting market data to develop the estimates of fair value. 5. Long-Term Obligations At December 31, 1998, long-term obligations consist of secured and unsecured term loans and secured borrowings used to acquire property and equipment, capital lease arrangements and a leasehold improvement financing obligation. In May 1997, we obtained a $5.0 million term loan to payoff pre-existing debt, finance capital asset acquisitions and finance continued research and clinical development. The loan is payable in thirty-six equal monthly installments and the interest rate is 14.58%. The lender was granted warrants to purchase 10,000 shares of common stock at $125.00 per share, which are exercisable over a ten-year period. We have attributed a value of $648,000 to these warrants. This amount has been recorded as a discount on the related debt and is being amortized as interest expense over the term of the loan. In June 1997, we issued $10.4 million of senior convertible notes with an original maturity of August 2000. Interest, at 5.5% per annum, on the notes was payable in common stock or cash at our option. Initially, the notes were convertible into common stock at 100% of the low trading price during a designated time period prior to conversion provided that the conversion price would not be less than $110.00 per share. Starting in November 1997, the notes were convertible into common stock at a 10% discount from the low trading price during a designated time period prior to the conversion, with a floor of $110.00 through March 31, 1998, pursuant to a March 1998 amendment agreement with the note holders whereby we issued to the note holders three-year warrants to purchase an aggregate of 6,875 shares of common stock at an exercise price of $150.00 per share as consideration for entering into the amendment agreement. We have attributed a value of $309,000 to these warrants. This amount was recorded as a discount on the related debt and was amortized as interest expense over the term of the loan. Of the notes issued, $400,000 was issued to the placement agent as part of the placement fee. We paid the placement agent an additional $300,000 in cash. The placement fees and other offering costs have been capitalized in other assets as deferred issuance costs and were amortized to interest expense over the life of the notes to the extent the notes were not converted to common stock. The net proceeds totaled approximately $9.5 million after the placement agent's fees and other offering expenses. In connection with the issuance of the notes, we recognized a non-cash charge in the amount of $3,692,000, representing the value attributed to the in-the-money conversion feature of the senior convertible notes. Through December 9, 1998, an aggregate principal balance of approximately $5.6 million of the Senior Convertible Notes was converted into an aggregate of 128,563 shares of common stock. On December 10, 1998, we issued to the note holders an aggregate of 4,784 shares of our Series D Convertible Preferred Stock in exchange for the cancellation of an aggregate of $4.8 million (including accrued interest) of the notes. Equipment borrowings totaled $401,555 and $0 at December 31, 1997 and 1998, respectively. The borrowings carried interest at rates ranging from 10.7% to 12.75% at December 31, 1997, were secured by the equipment acquired, and were payable in monthly installments ranging from $10,000 to $156,000 through December 1998. We also acquired certain equipment and furniture pursuant to capital lease arrangements. The gross amount of equipment and furniture and the related accumulated amortization recorded under capital leases included in property and equipment are as follows: 1997 1998 ------------ ------------ At December 31, Equipment and furniture $ 1,890,164 $ 2,401,286 Less accumulated amortization (1,354,475) (1,668,460) ------------ ------------ $ 535,689 $ 732,826 ============ ============ Amortization of assets acquired under capital leases is included in depreciation and amortization expense. In connection with the facility lease described in Note 6, we entered into an agreement with the former tenant of the facility to acquire approximately $1.5 million of tenant improvements by making annual payments to the former tenant, including accrued interest of $540,000 in 1999 through 2002. The 1998 payment was not paid until January 1999. F-13 Fair Value of Long-Term Obligations The fair values of our long-term obligations are estimated using discounted cash flow analyses based on our current incremental borrowing rate for similar types of borrowing arrangements. The carrying amounts and fair values of long-term obligations consisted of the following at December 31, 1998: Carrying Value Fair Value -------------- ---------- Leasehold improvements financings $ 2,032,045 $ 2,213,059 Secured Loan $ 2,724,189 $ 2,414,913 The carrying value of our term loan approximates our fair value because the interest rates on the note takedowns are periodically reset. At December 31, 1998, future payments on long-term obligations are as follows: Leasehold Secured Capital Improvement Loan Leases Financing Total ----------- -------- ------------ ----- 1999 $1,893,219 $ 257,889 $1,080,000 $3,231,108 2000 830,970 281,333 540,000 1,652,303 2001 - 270,635 540,000 810,635 2002 - 60,673 540,000 600,673 2003 - - - - ----------- ---------- ----------- ----------- Total minimum payments $2,724,189 $ 870,530 $2,700,000 $6,294,719 Less amount representing interest (at rate ranging from 9.5% to 12.0%) - (119,766) (667,955) (787,721) ----------- ---------- ----------- ----------- 2,724,189 750,764 2,032,045 5,506,998 Less current installments (1,893,219) (219,232) (691,410) (2,803,861) ----------- ---------- ----------- ----------- Long-term obligations, excluding current installments $ 830,970 $ 531,532 $1,340,635 $2,703,137 =========== ========== =========== ========== 6. Commitments and Contingencies We lease our research and office facility in South San Francisco, California under a noncancellable agreement expiring 2003, with options to renew for a total of ten years. We are required to pay operating costs, including property taxes, utilities, insurance and maintenance. At December 31, 1998, the minimum noncancellable future rental payments under our operating leases are: 1999 $ 1,210,837 2000 1,544,555 2001 1,590,892 2002 1,638,618 2003 281,296 ------------ $ 6,266,198 ============ Rent expense for each of the three years ended December 31, 1996, 1997 and 1998 was approximately $1,348,000 $1,154,000 and $1,189,000, respectively. We are involved in a litigation and disputes which are incidental to our business. While it is not possible to predict or determine the outcome of such litigation and disputes, or to provide an estimate of the losses, if any, that may arise, we believe the costs associated with all of these actions will not have a material effect on our consolidated financial position or liquidity, but could possibly be material to the consolidated results of operations. F-14 Further, product liability claims may be asserted in the future relative to events not known to management at the present time. We have insurance coverage which we believe is adequate to protect against such product liability losses as could materially affect our financial position. 7. Contractual Agreements We have entered into license, clinical trial and supply agreements with universities, research organizations and commercial companies. Certain of these agreements require payments of royalties on future sales of resulting products and may subject us to minimum annual payments to our contract partners. In addition, we signed an agreement in 1995 which could result in the payment of milestone installments if certain development objectives are achieved. To date, payments under these agreements have not been significant and, at December 31, 1998, related noncancellable commitments are immaterial. 8. Stockholders' Equity Preferred Stock We are authorized to issue 1,000,000 shares of preferred stock (519,533 shares of which are issued and outstanding at December 31, 1998). Our Board of Directors may set the rights and privileges of any preferred stock issued. On December 10, 1998, we and certain institutional investors exchanged an aggregate of $4.8 million (including accrued interest) of the Senior Convertible Notes (the "Notes") for an aggregate of 4,784 shares of our Series D Convertible Preferred Stock. Each share of Series D Convertible Preferred Stock is entitled to receive, when, as, and if declared by the Board of Directors out of funds legally available for such purpose, cumulative dividends at the rate of $55 per annum. Dividends on the Series D Preferred Stock are payable in cash or shares of our common stock or any combination of cash and shares of common stock, at our option and are payable quarterly on February 1, May 1, August 1 and November 1 of each year. Each share of Series D Preferred Stock is convertible, at any time, into common stock at the lesser of (a) $22.50 per share or (b) 90% of the low trading price during a designated time period prior to the conversion. In addition, the holders received an aggregate of 38,373 warrants to purchase additional shares of common stock in exchange for surrendering the redemption rights previously held by them under the Notes. The warrants were priced at 150% of the average closing price for the month of December 1998. We have attributed a value of $943,680 to these warrants. In connection with the issuance of the Series D Preferred Stock, we also recognized a non-cash charge in the amount of $1,063,605, representing the value attributed to the in-the-money conversion feature of the Series D Preferred Stock. The delisting of our common stock from The Nasdaq National Market constituted an Optional Redemption Event (as defined in the Certificate of Designation of Series D Preferred Stock) for the Series D Preferred Stock. In connection therewith, on February 4, 1999, we issued a Control Notice (as defined in the Certificate of Designation of Series D Preferred Stock) that prevented the redemption of the Series D Preferred Stock. This Control Notice will remain in effect for as long as we are not listed on any of The Nasdaq National Market, The Nasdaq SmallCap Market, the American Stock Exchange or the New York Stock Exchange. Delivery of the Control Notice had the effect of increasing the annual dividend to $180 per share and adjusting the conversion price of the Series D Preferred Stock to 80% of the amount the conversion price would otherwise be. In October 1998, we completed the sale to the public of an aggregate of 140,880 shares of our Series C Convertible Preferred Stock for aggregate gross proceeds of $14.1 million. Each share of Series C Preferred Stock is entitled to receive cumulative dividends paid semi-annually to the holders of record of such shares as follows: (i) an annual stock-on-stock dividend, paid in arrears, in shares of common stock (calculated as the quotient of $10.00 divided by 85% of the average closing price of the common stock for the 10-day trading period ending three trading days prior to the date the dividend is paid); plus (ii) a cash amount equaling 0.00005% of our U.S. net sales of our SP-303/Provir product for the treatment of diarrhea, if any, for the preceding two calendar quarters less $5.00. If, under Delaware law, we are unable to pay the cash portion of the dividends, then the cash portion will be paid in shares of common stock (valued at 85% of the average closing price of the common stock for the 10-day trading period ending three trading days prior to the date on which the dividend is paid). We intend to honor this royalty portion of the dividend through the sale of our first botanical product, if any. Each share of the Series C Preferred Stock was convertible for a period of 30 days after the first issuance and will be convertible again commencing 12 months after the initial issuance date (August 18, 1998) at the election of each holder, and automatically on the sixth anniversary of the initial issuance date into greater of (a) 0.8333 shares of common stock or (b) such number of shares of common stock as equals $100 (the price paid per share of Series C Preferred Stock) divided by 85% of the average closing price of the common stock reported by Nasdaq for the 10-day trading F-15 period ending three trading days prior to the date of conversion. The common stock is currently trading on The Nasdaq OTC Bulletin Board. During the initial 30-day conversion period for the Series C Preferred Stock, 24,922 shares of the Series C Preferred Stock were converted into an aggregate of 93,077 shares of common stock. In connection with the issuance of the Series C Preferred Stock, we recognized a non-cash charge in the amount of $678,636. In June 1998, we entered into Stock Purchase Agreements with certain of our stockholders pursuant to which we acquired the right to sell to these stockholders, subject to certain conditions up to an aggregate of 7,000 shares of Series B Custom Convertible Preferred Stock for an aggregate purchase price of $7,000,000. The stock purchase agreements were terminated upon the closing of the Series C Convertible Preferred Stock Financing in October 1998. As consideration for entering into the stock purchase agreements, we issued to these stockholders warrants to purchase an aggregate of 17,500 shares of common stock. The warrants are exercisable for a period of five years at an exercise price per share equal to 115% of the average trading price of the common stock during specified measurement periods. We have attributed a value of $1.5 million to these warrants. In July 1996, we closed a private placement pursuant to Regulation S under the Securities Act of 1933, as amended, in which it received gross proceeds of $3.3 million for the sale of 400,000 shares of Series A Convertible Preferred Stock and for the issuance of a six-year warrant to purchase 27,500 shares of common stock at an exercise price of $203.60 per share. The Preferred Stock does not carry a dividend obligation and will convert into common stock no later than July 23, 1999 at a price per share between $120.00 and $163.00, depending on the market value of common stock during the period prior to conversion. The holder of preferred shares is entitled to a liquidation preference of 163.00 per share. Common Stock In December 1992, we adopted the 1992 Stock Option Plan (the "Plan") as the successor plan to our 1990 Stock Option Plan. The Plan will terminate on the earlier of December 31, 2002 or the date on which all shares available for issuance under the Plan have been issued or canceled. The Plan provides for two separate components: the Discretionary Option Grant Program and the Automatic Option Grant Program. Under the Discretionary Option Grant Program, options granted may either be incentive options or non-statutory options. Incentive options may be granted to employees at a price not less than the fair market value of Common Stock on the grant date. Non-statutory options may be granted at a price determined by the plan administrator. Each option granted is exercisable as determined by the plan administrator, with a term not to exceed ten years. The Plan also allows for the granting of options with repurchase rights and stock appreciation rights at the discretion of the plan administrator. Under the Automatic Option Grant Program, each individual who becomes a non-employee board member on or after the effective date of the Plan is automatically granted a non-statutory stock option to purchase 1,000 shares of common stock. Further, each non-employee board member who has served as a member for at least six months prior to the annual stockholders' meeting is automatically granted an annual non-statutory stock option to purchase not more than 375 nor less than 250 shares of common stock, depending on a calculation based on the average selling price of the common stock. The exercise price of each option granted is the fair value of the common stock on the date of grant. These options have a ten-year term and vest over 24 months. On September 18, 1998, the Plan Administrator implemented an option cancellation/regrant program for all employees of the Company, including our executive officers. Pursuant to that program, each such employee was given the opportunity to surrender his or her outstanding options under the Plan with exercise prices in excess of $25.62 per share in return for a new option grant for the same number of shares but with an exercise price of $25.62 per share, the closing selling price per share of common stock as reported on the Nasdaq National Market on the September 18, 1998 grant date of the new option. Options for a total of 92,760 shares with a weighted average exercise price of $105.50 per share were surrendered for cancellation, and new options for the same number of shares were granted with the $25.62 per share exercise price. To the extent the higher-priced option was exercisable for any option shares on the September 18, 1998 cancellation date, the new option granted in replacement of that option will become exercisable for those shares in a series of twelve (12) successive equal monthly installments upon the optionee's completion of each month of service over the one (1) year period measured from the September 18, 1998 grant date. The option will become exercisable for the remaining option shares in one or more installments over the optionee's period of continued service, with each such installment to vest on the same vesting date in effect for that installment under the cancelled higher-priced option. On October 20, 1998, the Plan Administrator implemented an option cancellation/regrant program for the non-employee Board members (excluding the Plan Administrator) and certain key independent consultants holding options F-16 under the Plan. Pursuant to the October program, each such individual was given the opportunity to surrender his or her outstanding options under the Plan with exercise prices in excess of $28.75 per share in return for a new option grant for the same number of shares but with an exercise price of $28.75 per share, the closing selling price per share of common stock as reported on the Nasdaq National Market on the October 20, 1998 grant date of the new option. Options for a total of 29,232 shares with a weighted average exercise price of $122.46 per share were surrendered for cancellation, and new options for the same number of shares were granted with the $28.75 per share exercise price. To the extent the higher-priced option was exercisable for any option shares on the October 20, 1998 cancellation date, the new option granted in replacement of that option will become exercisable for those shares in a series of twelve (12) successive equal monthly installments upon the optionee's completion of each month of service over the one (1) year period measured from the October 20, 1998 grant date. The option will become exercisable for the remaining option shares in one or more installments over the optionee's period of continued service, with each such installment to vest on the same vesting date in effect for that installment under the cancelled higher-priced option. Both programs provide for automatic acceleration of the exercise period in the event of certain corporate transactions, including a merger, asset sale or change in control of the Company. The 1990 Stock Option Plan provided for the granting of incentive and non-statutory stock options. Both types of options were immediately exercisable and expire ten years from the date of grant. Vesting of optioned shares was determined by the board of directors and generally occurred over a two- to four-year period from the date of grant. At December 31, 1998, all options to purchase common stock issued under this plan were vested. A summary of stock option activity is as follows: Options Outstanding ------------------------------------------------------ Weighted Weighted Average Average Number Price Per Exercise Fair Value of Shares Share Price At Grant Date --------- --------------- --------- ----------- Balance at December 31, 1996 105,099 $1.20--$265.00 $109.60 Granted at fair value 47,577 82.60-- 136.20 108.20 $69.20 Exercised (974) 4.80-- 117.60 65.80 Forfeited (12,115) 70.00-- 265.00 128.00 ----------- Balance at December 31, 1997 139,587 1.20-- 265.00 108.00 Granted at fair value 221,017 25.62-- 98.75 29.79 $29.81 Exercised (792) 1.20-- 70.00 27.41 Forfeited (139,135) 25.62-- 265.00 110.84 ----------- Balance at December 31, 1998 220,677 $1.20-- 215.00 $ 28.13 =========== At December 31, 1998, 30,407 shares under options were exercisable at a weighted average exercise price of $33.19 per share (65,502 shares under options were exercisable at a weighted average exercise price of $105.00 per share at December 31, 1997). A stock option grant of 75,000 shares of common stock granted on September 18, 1998 at an exercise price of $25.62 per share was pending stockholder approval. F-17 The following table summarizes information regarding stock options outstanding at December 31, 1998: Weighted Shares under Options Average Exercisable at Option Shares Contractual Weighted December 31, 1998 Range of Outstanding at Remaining Average --------------------------- Exercise December 31, Life Exercise Weighted Average Prices 1998 (Years) Price Number Exercise Price ---------------- ---------------- ------------- ---------- -------- ---------------- $1.20 - $ 30.00 209,767 9.36 $ 25.40 26,650 $ 20.74 40.63 - 72.50 7,275 9.32 52.71 1,177 70.34 82.50 - 107.50 1,271 8.87 100.26 662 100.62 127.50 - 162.50 1,862 7.81 140.90 1,416 142.54 210.00 - 215.00 502 4.00 210.02 502 210.02 ---------- -------- $1.20 - $215.00 220,677 9.33 $ 28.13 30,407 $ 33.19 ========== ======== For certain options issued during the years ended December 31, 1993 and 1994, we recorded deferred compensation for the difference between the exercise price and the fair market value of common stock at the date of grant. For certain additional options issued during the years ended December 31, 1997 and 1998 to non-employees, we recorded deferred compensation expense for the fair value of the options at the date of grant. Deferred compensation is amortized to expense on a straight-line basis over the vesting period of the options. Pro Forma Information We have elected to follow Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees ("APB 25"), and related interpretations in accounting for our employee stock options because, as discussed below, the alternative fair value accounting provided for under SFAS 123 requires use of option valuation models that were not developed for use in valuing employee stock options. Under APB 25, because the exercise price of our employee stock options equals the market price of the underlying stock on the date of grant, no compensation expense is recognized. Pro forma information regarding net loss and net loss per share is required by SFAS 123, and has been determined as if we had accounted for our employee stock options granted subsequent to December 31, 1994 under the fair value method of SFAS 123. The fair value for these options was estimated at the date of grant using the Black-Scholes option pricing model. The following are the weighted-average assumptions for 1996, 1997 and 1998, respectively: risk-free interest rates of 5.73%, 6.27% and 4.57%; no dividends paid; volatility factors of the expected market price of common stock of .75 and a weighted-average expected life of the options of 3.85, 5.0 and 3.84 years. The effects of applying FAS 123 for recognizing compensation expense and providing pro forma disclosures in 1998, 1997 and 1996 are not likely to be representative of the effects on reported net income in future years. The Black-Scholes option valuation model was developed for use in estimating the fair value of traded options which have no vesting restrictions and are fully transferable. In addition, option valuation models require the input of highly subjective assumptions including the expected stock price volatility. Because our employee stock options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, in management's opinion, the existing models do not necessarily provide a reliable single measure of the fair value of our employee stock options. For purposes of pro forma disclosures, the estimated fair value of the options is amortized to pro-forma net loss over the options' vesting periods. Our pro forma information follows (in thousands except for net loss per share information): 1996 1997 1998 --------- --------- --------- Net loss applicable to Common Stockholders Historical $(18,790) $(29,289) $(38,524) Pro forma $(20,280) $(31,101) $(40,734) Net loss per common share Historical $ (27.85) $ (34.44) $ (38.31) Pro forma $ (30.05) $ (36.57) $ (40.50) F-18 Reserved Shares At December 31, 1998, 386,781 shares of common stock were reserved for conversion of outstanding preferred stock and for issuance upon exercise of outstanding options, warrants and options available for future grant. The reserved shares excluded shares issuable upon conversion of Series C Preferred Stock and 145,189 shares issuable upon exercise of the Company's stock options which are exercisable after May 31, 1999. Warrants A summary of outstanding warrants to purchase common stock at December 31, 1998 is as follows: Number of Exercise Term Description Warrants Price in Year Expiration ------------------------------------ --------------- ---------------- ------- ------------- Lease financing arrangements 4,585 $48.00 - $216.60 5 - 7 2000 - 2002 Series A Convertible Preferred Stock 27,500 $203.68 6 2002 Secured term loan 10,000 $125.00 10 2007 Senior convertible notes 6,875 $150.00 3 2001 Series B Convertible Preferred Stock 17,500 $53.00 - $ 96.40 5 2003 Series D Convertible Preferred Stock 38,373 $61.40 5 2003 --------- 104,833 ========= 9. Taxes As of December 31, 1998, we had federal net operating loss carryforwards of approximately $141.2 million. The net operating loss and credit carryforwards will expire at various dates beginning in 2004 through 2013, if not sooner utilized. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting and the amounts used for income tax purposes. Significant components of our deferred tax assets and liabilities for federal and state income taxes as of December 31, 1997 and 1998 are as follows: 1997 1998 ------------ ------------ Deferred tax assets: Net operating loss carryforwards $ 35,200,000 $ 48,600,000 Research credits (expiring in 2004--2013) 2,800,000 3,900,000 Capitalized research and development costs 4,700,000 6,400,000 Other 400,000 (1,200,000) ------------ ------------ Total deferred tax assets 43,100,000 57,700,000 Valuation allowance for deferred tax assets (43,100,000) (57,700,000) ------------ ------------ Net deferred tax asset $ - $ - ============= ============= The net valuation allowance increased by $14.6 million during the year ended December 31, 1998. Utilization of the net operating losses and credits may be subject to a substantial annual limitation due to the "change in ownership" provisions of the Internal Revenue Code of 1986 and similar state provisions. The annual limitation may result in the expiration of net operating losses and credits before utilization. 10. Subsequent Events In April 1999, directors of the Company holding stock options to purchase an aggregate of 131,717 shares of common stock agreed to surrender these options to the Company for cancellation. On April 5, 1999, the Company entered into a credit facility and note purchase agreement with certain investors, stockholders, officers and members of the board of directors (the "Credit Agreement"), pursuant to which the Company 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 the Company's equity securities, or September 1, 1999 (the "Convertible Promissory F-19 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 the Company and be convertible into shares of the class and series of equity securities offered by the Company in the public offering, or into common stock if no such offering occurs prior to December 31, 1999. In connection with the Credit Agreement, the Company 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 common stock, or 1/3 of the five-day weighted average trading price of the Company's common stock for the period ending three trading days prior to conversion or exercise. In April 1999, the Company entered into an amendment agreement with an existing lender to permit the issuance by the Company of the Convertible Promissory Notes. In connection with the amendment, the Company issued a warrant to purchase shares of the class and series of equity securities offered by the Company in the first registered public offering by the Company 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 common stock, or 1/3 of the five-day weighted average trading price of the common stock for the period ending three trading days prior to conversion or exercise. On June 11, 1999, the stockholders approved, and on June 22, 1999 the Company effected, a one-for-twenty reverse stock split of the Company's outstanding common stock. All common shares and per common share amounts have been restated to reflect the reverse stock split in all periods presented.

Indemnification of Directors and Officers. Section 145 of the Delaware General Corporation Law, as amended (the "DGCL"), provides that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal or investigative (other than an action by or in the right of the corporation) by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding, if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe the person's conduct was unlawful. Section 145 further provides that a corporation similarly may indemnify any such person serving in any such capacity who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor, against expenses actually and reasonably incurred in connection with the defense or settlement of such action or suit if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Delaware Court of Chancery or such other court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper. Section 102(b)(7) of the DGCL permits a corporation to include in its certificate of incorporation a provision eliminating or limiting the personal liability of a director to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, provided that such provision shall not eliminate or limit the liability of a director (i) for any breach of the director's duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL (relating to unlawful payment of dividends and unlawful stock purchase and redemption) or (iv) for any transaction from which the director derived an improper personal benefit. The Registrant's Amended and Restated Certificate of Incorporation provides that the Registrant's directors shall not be liable to the Registrant or its stockholders for monetary damages for breach of fiduciary duty as a director, except to the extent that exculpation from liabilities is not permitted under the DGCL as in effect at the time such liability is determined. The Registrant has entered into indemnification agreements with all of its officers and directors, as permitted by the DGCL. II-1 Item 15. Recent Sales of Unregistered Securities. Since May 1996, we have sold and issued the following unregistered securities (the share numbers and per share prices below reflect the one-for-twenty reverse stock split of the outstanding common stock effected on June 22, 1999): (1) In June 1999, we agreed to issue to Michael Tempesta, prior to July 15, 1999, in connection with the settlement of litigation between Mr. Tempesta and Shaman, 16,667 shares of Series R Preferred Stock. (2) In April 1999, we issued to MMC/GATX Partnership No. 1 in connection with the amendment of a loan agreement with GATX a cashless exercise warrant to purchase 39,512 shares of the class and series of equity securities which are being registered under this registration statement, which is the Series R Preferred Stock. This Warrant is exercisable upon the effectiveness of this registration statement and through the seventh anniversary date of the earlier to occur of (1) December 31, 1999, and (2) the effective date of this registration statement, subject to acceleration upon certain events. The per share exercise price will be $15.00, which is the per share price at which the Series R Preferred Stock is being sold in this offering. (3) In April 1999, we also issued to various lenders who were either existing stockholders, key executives or directors cashless exercise warrants to purchase 33,600 shares of the class and series of equity securities which are being registered under this registration statement, which is the Series R Preferred Stock. These warrants are exercisable upon the consummation of the sale of the Series R Preferred Stock registered under this registration statement and through the third anniversary date of such consummation, subject to acceleration upon certain events. The per share exercise price will be $15.00, which is the per share price at which the Series R Preferred Stock is being sold in this offering. (4) In connection with the April 1999 debt offering, each lender was also issued a senior subordinated secured convertible promissory note convertible after the consummation of the Series R Preferred Stock offering and prior to the earlier to occur of (i) January 1, 2000 and (ii) thirty days following the consummation date of the offering into an aggregate of 67,201 shares of the Series R Preferred Stock at a conversion price of $15.00 per share. (5) In May 1997, we obtained a $5.0 million term loan to pay off preexisting debt, finance capital asset acquisition and finance continued research and development. The lender was granted warrants to purchase 10,000 shares of common stock at an exercise price of $125.00 per share. These warrants expire May 7, 2007. (6) On December 10, 1998, Shaman and certain institutional investors exchanged an aggregate of $4.8 million, including accrued interest, of senior convertible notes for common stock and an aggregate of 38,373 warrants to purchase additional shares of common stock in exchange for surrendering the redemption rights previously held by them under the notes. The warrants were priced at 150% of the average closing price for the month of December 1998. The sales of the above securities were deemed to be exempt from registration under the Securities Act of 1933, as amended, in reliance on Section 4(2) of the Securities Act. In each such transaction, the recipients of securities represented their intentions to acquire the securities for investment only and not with a view to or for sale in connection with any distribution thereof and appropriate legends were affixed to the securities issued in such transactions II-2 Item 16.

The undersigned Registrant hereby undertakes: (A) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement: II-5 (1) to include any prospectus required by Section 10(a)(3) of the Securities Act; (2) to reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement. Notwithstanding the foregoing, any increase or decrease in the volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimates maximum offering range may be reflected in the form of prospectus filed with the commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the "Calculation Of Registration Fee" table in the effective registration statement; and (3) to include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement; provided, however, that paragraphs (1) and (2) do not apply if the information required to be included in a post-effective amendment by these paragraphs is contained in periodic reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the Registration Statement. (B) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (C) To remove from registration by means of a post-effective amendment any of the securities being registered that remain unsold at the termination of the offering. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue. The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. The undersigned Registrant hereby undertakes that: (1) For purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus filed as part of this Registration Statement in reliance upon Rule 430A and contained in a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this Registration Statement as of the time it was declared effective. (2) For purposes of determining any liability under the Securities Act, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
