SHAMAN PHARMACEUTICALS, INC. NOTES TO CONDENSED FINANCIAL STATEMENTS September 30, 1996 (Unaudited) 1. Basis of Presentation Shaman Pharmaceuticals, Inc. ("Shaman" or the "Company") discovers and develops novel pharmaceutical products for major human diseases by isolating active compounds from tropical plants. The Company has three compounds in clinical development: Provir(TM), an oral product for the treatment of watery diarrhea; Virend(R), a topical antiviral for the treatment of herpes; and nikkomycin Z, an oral antifungal for the treatment of endemic mycoses. Shaman has collaborations for the development of diabetes drugs with Lipha, Lyonnaise Industrielle Pharmaceutique S.A. ("Lipha"), a wholly owned subsidiary of Merck KGaA, Darmstadt, Germany and with Ono Pharmaceutical Co., Ltd. ("Ono") of Osaka, Japan. The accompanying unaudited condensed financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and in accordance with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair presentation have been included. The results of operations for the interim periods shown herein are not necessarily indicative of operating results for the entire year. This unaudited financial data should be read in conjunction with the audited financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 1995, filed with the Securities and Exchange Commission on April 1, 1996. Operating expenses for 1995 have been reclassified to conform to 1996 presentation. 2. Collaborative Agreement In September 1996, the Company entered into a five-year collaborative agreement with Lipha to jointly develop antidiabetic drugs. In exchange for development and marketing rights in all countries except Japan, South Korea, and Taiwan (which are covered under an earlier agreement between Shaman and Ono), Lipha will provide up to $9.5 million in research payments and up to $10 million in equity investments priced at a 20% premium to the average market price of the Company's common stock at the time of purchase. Complete research funding under the collaboration is dependent upon the initiation of human clinical trials of at least one compound by September 23, 1998. The agreement also provides for additional preclinical and clinical milestone payments to the Company in excess of $10 million per compound for each antidiabetic drug developed and commercialized. Lipha will bear all pre-clinical, clinical, regulatory and other development expenses associated with the compounds selected under the agreement. In addition, as products are commercialized, Shaman will receive royalties on all product sales outside the United States and up to 50% of the profits (if the Company exercises its co-promotion rights) or royalties on all product sales in the United States. Certain of the milestone payments will be credited against future royalty payments, if any, due to the Company from sales of products developed pursuant to the agreement. Upon signing the collaboration, the Company received an annual research fee of $1.5 million which will be amortized over twelve months. Shaman recognized $31,250 in revenue from the Lipha collaboration at September 30, 1996. The Company also received $3 million for 388,918 shares of common stock priced at $7.71 per share, representing a 20% premium to the weighted average price of the Company's stock at the time of purchase. 3. Preferred Equity Financing In July 1996, the Company closed a private placement pursuant to Regulation S under the Securities Act of 1933, as amended, in which it received approximately $3.3 million for 400,000 shares of Series A Convertible Preferred Stock ("Preferred Stock") priced at $8.147 per share and a six-year warrant to purchase 550,000 shares of the Company's common stock at an exercise price of $10.184 per share. The Preferred Stock does not carry a dividend obligation and is convertible into common stock at the earlier of (a) the investor's option, (b) immediately following any 60 trading day period in which the Company's common stock has consistently traded higher than $8.147, or (c) July 23, 1999. If the Preferred Stock converts prior to July 23, 1999, the conversion ratio will be one share of common stock for each share of preferred. If the Preferred Stock converts on July 23, 1999, the conversion rate will be the higher of $6.00 or a weighted average price of the Company's common stock at the time of conversion. In either case, appropriate adjustments will be made for stock dividends, splits or other adjustments. In addition to the initial sale of Preferred Stock and warrant, the Company has the right, from time to time during the period beginning January 1997 and ending July 2000, to sell up to 1,200,000 shares of common stock to the investor at a premium over an average of the Company's market price at the time of sale. As the Company exercises its rights under the agreement, the investor has the option to increase the shares purchased by up to 577,500 shares. 4. Term Loan The Company's unsecured term loan provided for the acceleration of principal if the Company did not achieve certain financing or collaborative objectives by May 15, 1996. The Company achieved the specified milestone in the third quarter rather than by May 15, 1996, and the lender accelerated the amortization schedule. The acceleration provisions require that principal amortization be shortened from 30 months to 24 months, with the first monthly payment due May 15, 1996 instead of April 30, 1997. Accordingly, to date the Company has made six principal payments totaling $625,000 and reclassified $1,250,000 of its term debt to current liabilities as of September 30, 1996. The interest rate on the loan was approximately 7.1% at September 30, 1996. Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations Overview Shaman Pharmaceuticals, Inc. ("Shaman" or the "Company") discovers and develops novel pharmaceutical products for major human diseases by isolating active compounds from tropical plants. The Company has three compounds in clinical development: Provir(TM), an oral product for the treatment of secretory diarrhea; Virend(R), a topical antiviral for the treatment of herpes; and nikkomycin Z, an oral antifungal for the treatment of endemic mycoses. Shaman has collaborations for the development of diabetes drugs with Lipha, Lyonnaise Industrielle Pharmaceutique S.A. ("Lipha"), a wholly owned subsidiary of Merck KGaA, Darmstadt, Germany and with Ono Pharmaceutical Co., Ltd. ("Ono") of Osaka, Japan. The Company began operations in March 1990. To date, Shaman has not sold any products and does not anticipate receiving product revenue in the near future. The Company's accumulated deficit at September 30, 1996, was approximately $79 million. Shaman expects to continue to incur substantial losses over the next several years, due primarily to the expense of preclinical studies, clinical trials and its on-going research program. The Company expects that losses will fluctuate from quarter to quarter and that such fluctuations could be substantial. Shaman has financed its research, development and administrative activities through various private placements of its equity securities, an initial public offering of common stock in January 1993, a secondary offering in December 1993, collaborative agreements with research partners, and, to a lesser extent, through equipment and leasehold improvement financings. In November 1996, Shaman completed a successful Phase II trial of Provir, an oral agent for the treatment of secretory diarrhea. The open label trial tested Provir in 75 patients afflicted with acute diarrhea, including traveler's diarrhea and non-specific diarrhea of unknown etiology. Overall, 89% of the 75 patients treated with Provir returned to normal bowel function after 48 hours of treatment. Moreover, of the 71 patients available for follow up, no recurrence was experienced during the post-treatment period. No significant adverse reactions were reported. The Company plans to initiate a 500 patient, randomized, multi-dose, placebo-controlled study early in 1997. Shaman obtained an initial indication of efficacy for Virend, a topical agent for the treatment of genital herpes, in late 1995. Focusing on a two-pronged strategy for development and commercialization of the product, the Company intended to conduct a Phase III trial in late 1996 in immunocompromised patients followed by a combination trial with the standard of treatment for genital herpes (acyclovir), in order to outlicense Virend for development and commercialization in the immunocompetent patient population. As a result of discussions with potential partners and consideration of the market opportunity in the immunocompetent patient population, Shaman has decided to initiate a combination study prior to a Phase III trial in the AIDS patient population. Because of differing mechanisms of action, Shaman believes that Virend may have an additive or synergistic benefit when used in combination with acyclovir. Successful results from a combination trial could lead to more attractive partnering opportunities with better market potential than that anticipated by the original strategy. Shaman plans to enter a Phase I human clinical trial of nikkomycin Z, an oral treatment for endemic mycoses. The trial, designed to determine that nikkomycin Z is safe, is scheduled to begin in the fourth quarter of 1996. In September 1996, the Company entered into a five-year collaborative agreement with Lipha to jointly develop antidiabetic drugs. In exchange for development and marketing rights in all countries except Japan, South Korea, and Taiwan (which are covered under an earlier agreement between Shaman and Ono), Lipha will provide up to $9.5 million in research payments and up to $10 million in equity investments priced at a 20% premium to the average market price of the Company's common stock at the time of purchase. Complete research funding under the collaboration is dependent upon the initiation of human clinical trials of at least one compound by September 23, 1998. The agreement also provides for additional preclinical and clinical milestone payments to the Company in excess of $10 million per compound for each antidiabetic drug developed and commercialized. To date, Shaman has identified ten orally active compounds which show preclinical activity as treatments for Type II diabetes. Lipha will bear all pre-clinical, clinical, regulatory and other development expenses associated with the compounds selected under the agreement. In addition, as products are commercialized, Shaman will receive royalties on all product sales outside the United States and up to 50% of the profits (if the Company exercises its co-promotion rights) or royalties on all product sales in the United States. Certain of the milestone payments will be credited against future royalty payments, if any, due to the Company from sales of products developed pursuant to the agreement. Upon signing the collaboration, the Company received an annual research fee of $1.5 million which will be amortized over twelve months. The Company also received $3 million for 388,918 shares of common stock priced at $7.71 per share, representing a 20% premium to the weighted average price of the Company's stock at the time of purchase. In July 1996, the Company closed a private placement pursuant to Regulation S under the Securities Act of 1933, as amended, in which it sold 400,000 shares of Series A Convertible Preferred Stock ("Preferred Stock") at a price per share of $8.147 and a six-year warrant to purchase 550,000 shares of the Company's common stock at a price of $10.184 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 $6 and $8.147, depending on the market value of the Company's common stock during the period prior to conversion. In addition to the sale of Preferred Stock and warrant, the Company has the right, from time to time during the period beginning January 1997 and ending July 2000, to sell up to 1,200,000 additional shares of common stock to the investor at a premium over an average of the Company's market price at the time of sale. The investor has the option to increase the shares purchased by up to 577,500 shares. Results of Operations Three Months and Nine Months Ended September 30, 1996 and September 30, 1995 The Company recorded revenues of $0.5 million for each of the quarters ended September 30, 1996 and 1995, and had revenues of $1.5 million and $1.7 million for the nine month periods ended September 30, 1996 and 1995, respectively. Revenues for both the three month and nine month periods ended September 30, 1996 resulted from collaborations for the research and development rights of Shaman's diabetes compounds, including revenue from the recently announced collaboration with Lipha, as well as ongoing revenues from Ono. Collaborative revenues in 1995 resulted solely from the Company's relationship with Ono and included a one-time access fee associated with the commencement of that collaboration. Research and development expenses were $4.8 million and $4.3 million for the quarters ended September 30, 1996 and 1995, respectively. Increased spending during the current quarter was primarily attributable to costs incurred for the Phase II Provir trial for secretory diarrhea and start-up costs associated with the Virend clinical trial expected to begin early in 1997. For the nine months ended September 30, 1996, research and development expenses were $14.2 million, representing a $1.6 million increase over the same period in 1995. The year-to-date increase is primarily attributable to the Company's additional pre-clinical activities with respect to nikkomycin Z and further development of the compounds identified in its diabetes research effort. Research and development expenses are likely to increase in upcoming quarters as the Company continues research and development activities for various product candidates. General and administrative expenses were $0.9 million for each of the quarters ended September 30, 1996 and 1995, and $2.6 million and $2.8 million for the nine month periods ended September 30, 1996 and 1995, respectively. Current general and administrative expenses are in line with the Company's plan and are not expected to increase substantially because the Company's expanded research and clinical activities are not expected to require commensurate increases in general and administrative support. Interest income was $.25 million and $.43 million for the quarters ended September 30, 1996 and 1995, respectively, and $.83 million and $1.3 million for the nine months ended September 30, 1996 and 1995, respectively. Interest income decreased for the periods ended September 30, 1996, compared with the periods ended September 30, 1995, due to lower average cash and investment balances as the Company continues to fund its operations. The increases in interest expense for the three and nine-month periods ending September 30, 1996 over the same periods in 1995 resulted from higher average debt balances in 1996, the impact of which was partially offset by a lower average interest rate on Company debt during 1996. Liquidity and Capital Resources As of September 30, 1996, the Company's cash, cash equivalents, and investments totaled approximately $20.4 million, compared with $26.7 million at December 31, 1995, with an average investment maturity of four and a half months at both dates. The Company invests excess cash according to its investment policy which provides guidelines with regard to liquidity, type of investment, credit rating, and concentration limits. During the quarter ended September 30, 1996, the Company received approximately $7.75 million from its first research payment under the Lipha collaboration, from the Lipha equity investment and from a private placement of preferred stock. Looking forward, the two transactions closed during the quarter provide on-going funding capability for the Company through equity financings and research funding. Additional cash was generated during the quarter through sales and maturities in the Company's investment portfolio. Lipha has committed an additional $15.0 million to the Company in the form of periodic research funding and annual purchases of premium-priced common stock. Complete funding under the collaboration is dependent upon the initiation of human clinical trials of at least one compound within two years. The Lipha agreement also provides for additional preclinical and clinical milestone payments in excess of $10 million per compound for each antidiabetic drug developed and commercialized, part of which may be offset against future royalties, if any. Further, Lipha will bear the preclinical, clinical trial and other development expenses associated with any antidiabetic compound which it selects. Shaman will receive royalties on antidiabetic product sales outside the United States and up to 50% of the profits (if the Company exercises its co-promotion rights) or royalties on all product sales in the United States. In July 1996, the Company received gross proceeds of $3.3 million for 400,000 shares of Series A Convertible Preferred Stock and a six-year warrant to purchase 550,000 shares of the Company's common stock at a price of $10.84 per share. In addition to the initial sale of the Preferred Stock and warrant, the Company has the right, from time to time during the period beginning January 1997 and ending July 2000, to sell up to 1,200,000 additional shares of common stock the investor at a premium over an average of the Company's market price at the time of sale. As the Company exercises its rights under the agreement, the investor has the option to increase the shares purchased by up to 577,500 shares. The Company expects to incur substantial additional costs relating to the continued clinical development of its products, its research and development programs, preclinical and clinical testing, and regulatory activities. At its current burn rate, the Company anticipates that its cash, cash equivalents and investment balances of approximately $20.4 million at September 30, 1996, the collaborative revenue committed by Lipha and Ono, Lipha's commitment to purchase additional equity and Shaman's additional rights to sell common stock through its private placement will be adequate to fund operations through 1997. Recognizing the need for additional financing, the Company continues to actively consider a variety of financing alternatives, including public and private equity financings, licensing arrangements for its other products, capital equipment financing, and term debt. To the extent the Company is successful in closing such transactions and creating such partnerships, cash balances would be enhanced through equity investments and fees. There can be no assurance that any of these sources of funds will be available to the Company on acceptable terms, if at all. Future Outlook In addition to historical information, this report contains predictions, estimates and other forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Actual results could differ materially from any future performance suggested in this report as a result of the risk factors set forth below under the caption "Risk Factors" and elsewhere in this report and in the Company's Annual Report on Form 10-K filed with the Securities and Exchange Commission on April 1, 1996. Risk Factors History of Operating Losses; Products Still in Development; Future Profitability Uncertain. Shaman's potential products are in research and development. In order to generate revenues or profits, the Company, alone or with others, must successfully develop, test, obtain regulatory approval and market its potential products. No assurance can be given that these product development efforts will be successful, that required regulatory approvals will be obtained, or that the products, if developed and introduced, will be successfully marketed or achieve market acceptance. Additional Financing Requirements and Uncertain Access to Capital Markets. The Company has significant long-term capital requirements and, in the event Shaman receives regulatory approval for any of its products, it will incur substantial expenditures to develop manufacturing, sales and marketing capabilities. The Company will need to raise additional funds for these purposes through additional equity or debt financings, collaborative arrangements with corporate partners or from other sources. No assurance can be given that such additional funds will be available to the Company to finance its development on acceptable terms, if at all. No Assurance of FDA Approval for Marketing; Government Regulation. The Company's activities with respect to research, preclinical development, clinical trials, manufacturing and marketing in the United States and other countries are subject to extensive regulation by numerous governmental authorities including, but not limited to, the Food and Drug Administration ("FDA"). The process of obtaining FDA and other required regulatory approvals is lengthy and requires the expenditure of substantial resources. Success cannot be assured. In order to obtain FDA approval, the Company must perform clinical tests to demonstrate to the FDA's satisfaction that a product is safe and effective for its intended uses. The Company may encounter problems in clinical trials which could cause the FDA or the Company to delay or suspend clinical trials. Further, the Company must demonstrate that it is capable of manufacturing bulk product to the relevant standards. There can be no assurance that any of the Company's future studies will demonstrate their intended result, that the Company's products will not have undesirable side effects that may prevent or limit their commercial use, or that the FDA will otherwise approve any of the Company's products. Dependence on Sources of Supply. The Company currently imports all of the plant materials from which its products are derived from countries in South and Latin America, Africa and Southeast Asia. To the extent that its products cannot be economically synthesized or otherwise produced, the Company will continue to be dependent upon a supply of raw plant material. While Shaman believes it has good relationships with the local governments and suppliers of these plant materials, the Company does not have formal agreements in place with all of its suppliers. Limited Manufacturing and Marketing Experience and Capacity. The Company currently produces products only in quantities necessary for clinical trials and partner requirements, and does not currently have the staff or facilities necessary to manufacture products in commercial quantities. As a result, the Company may rely on collaborative partners or third-party manufacturing facilities, which may not be available on commercially acceptable terms adequate for Shaman's long-term needs. The Company currently has no marketing or sales staff. To the extent that the Company does not or is unable to enter into co-promotion agreements or to arrange for third party distribution of its products, significant additional resources will be required to develop a marketing and sales force. Rapid Technological Change and Substantial Competition. The pharmaceutical industry is subject to rapid and substantial technological change. Technological competition from pharmaceutical companies, biotechnology companies and universities is intense. Many of these entities have significantly greater research and development capabilities, as well as substantial marketing, manufacturing, financial and managerial resources, and represent significant competition for the Company. There can be no assurance that developments by others will not render the Company's products or technologies noncompetitive or that the Company will be able to keep pace with technological developments. Uncertainty Regarding Patents and Proprietary Rights. The Company's success depends in part on its ability to obtain patent protection for its products and to preserve its trade secrets. No assurance can be given that the Company's patent applications will be approved, that any patents will provide the Company with competitive advantages for its products or that they will not be successfully challenged or circumvented by the Company's competitors. In addition, patents do not necessarily prevent others from developing competitive products. The Company has not conducted an exhaustive patent search and no assurance can be given that patents do not exist or could not be filed which would have an adverse effect on the Company's ability to market its products. Uncertainty of Health Care Reimbursement and Reform. Shaman's ability to successfully commercialize its products may depend in part on the extent to which reimbursement for the cost of such products and related treatments will be available from government health administration authorities, private health insurers and other organizations. Significant uncertainty exists as to the pricing, availability of distribution channels and reimbursement status of newly approved healthcare products. Possible Volatility of Stock Price. The market price of the Company's common stock, like the stock prices of many publicly traded biotechnology and smaller pharmaceutical companies, has been and may continue to be highly volatile. Environmental Regulation. In connection with its research and development activities and its periodic manufacturing of clinical trial materials, the Company is subject to federal, state and local laws, rules, regulations and policies governing the use, generation, manufacture, storage, air emission, effluent discharge, handling and disposal of certain materials and wastes. Although the Company believes that it has complied with these laws and regulations in all material respects and has not been required to take any action to correct any noncompliance, there can be no assurance that the Company will not be required to incur significant costs to comply with environmental and health and safety regulations in the future.

During a period beginning on the Effective Date through and including the fifth anniversary thereof (the "Research Period"), the Parties will collaborate in identifying potential Products for use within the Field. 2.2 Obligations of Shaman. 2.2.1 Collection and Screening of Plants. Unless otherwise decided by the Joint Research and Development Steering Committee, during each year of the Research Period, (the annual accounting period for this activity will begin on May 24, 1996 to coordinate with the Ono accounting cycle) Shaman shall (i) collect and screen in vivo for oral administration a minimum of one hundred (100) plants; (ii) provide the resources to move each Compound through the completion of Stage II(a) Development; (iii) use such assays as a tool in the purification and identification of the active Compounds to generate Lead Compounds; (iv) allocate at least twenty (20) full time equivalent ("FTE") scientists in the first three years under this Agreement and at least thirty (30) FTE scientists in the fourth and fifth years to carry out the obligations of Shaman under this Agreement; and (v) operate and expend resources in accordance with achieving Stage II(a) activities. 2.2.2 Presentation of Compounds. When Shaman discovers during the Research Period a Chemical Class containing a Compound or Compounds that have completed Stage II(a) activities, Shaman shall present such Chemical Class to LIPHA at the succeeding meeting of the Joint Research and Development Steering Committee, and provide LIPHA with the following concerning such Compound or Compounds from such Chemical Class: (i) structure, including structure elucidation data, (ii) patent filing documents, (iii) biological data, (iv) synthesization process, if any, (v) the complete ethnobotany and conservation dossier developed by Shaman through the date of presentation including all clinical assessment information collected by Shaman on the traditional use of such Compound in the Field, and (vi) any relevant information provided to Shaman by Ono. At the first meeting of the Joint Research and Development Steering Committee, to be scheduled within thirty (30) days following the Effective Date, Shaman shall deliver to LIPHA its Technical Information on the Initial Chemical Classes. Shaman will, upon LIPHA's request deliver to LIPHA information regarding any Compound sooner than the completion of Stage II(a) activities (but not earlier than Shaman's ability to determine the patentability of such Compound). 2.3 Obligations of LIPHA. 2.3.1 Acceptance of Compounds. LIPHA will determine which presented Compound or Compounds merit selection as a "Lead Compound" and shall do so not later than sixty (60) days following the meeting of the Joint Research and Development Steering Committee at which a Compound having completed Stage II(a) activities and meeting the Selection Criteria was presented by Shaman. Such selection shall be communicated to Shaman in writing within such sixty (60) day period and the selected Compound(s) shall thereafter be referred to as Lead Compounds. LIPHA may, however, select a Compound as a Lead Compound at an earlier time if it so chooses. Notwithstanding the foregoing, if Shaman has presented more than one Compound at a given time, LIPHA shall be given an additional sixty (60) days for each additional Compound, i.e. LIPHA would need to select a first Compound within sixty (60) days but could wait one-hundred and twenty (120) days before selecting the second Compound and one-hundred and eighty (180) days for the third Compound, etc. 2.3.2 Prioritization of Efforts. During the Research Period, LIPHA shall use its commercially reasonable efforts to perform its product development obligations under this Agreement in a fashion which is consistent with the commercial potential of the Products in the Field and in the Territory, and shall cooperate with Shaman in doing so. 2.3.3 Development and Selection Obligations; Lead Compounds. LIPHA shall have a period of * * * from the date on which it first selects a Compound as a Lead Compound (the "Evaluation Period") during which it must make further Compound selection determinations. Such determinations shall be made together with the appropriate milestone payments as set forth in Section 4.2.1. During the Evaluation Period LIPHA may conduct such other preclinical studies as LIPHA reasonably considers necessary to determine whether to pursue such Lead Compound(s) or Chemical Class for development under this Agreement. By selection of a Lead Compound LIPHA shall be deemed to have selected all other Compounds or analogs contained in the same Chemical Class as such Lead Compound. Consequently, LIPHA may conduct studies with respect to the Lead Compound, or analog or derivative within the same Chemical Class as such Lead Compound, but only so long as all payments prescribed in Section 4.2.1 have been made in a timely manner. If LIPHA develops an analog or derivative within the selected Chemical Class which it chooses to develop further and which derivative or analog meets the Selection Criteria, then LIPHA shall promptly so notify Shaman and such notification shall reset the starting point for the * * * Evaluation Period and for further milestone payments which may be due as set forth in Section 4.2 hereinafter. Any milestone payment previously made during the Evaluation Period for that Chemical Class will be credited against any such payment due with respect to the substituted Lead Compound. All rights to any Chemical Class that is not selected by LIPHA for development or which is abandoned by virtue of LIPHA's failing to make the appropriate milestone payments as set forth in Section 4.2.1, within the relevant Evaluation Period shall revert to Shaman, subject to Sections 2.3.4, 2.3.5 and 2.3.6. [* INDICATES THAT MATERIAL HAS BEEN OMITTED AND CONFIDENTIAL TREATMENT HAS BEEN REQUESTED THEREFOR. ALL SUCH OMITTED MATERIAL HAS BEEN FILED SEPARATELY WITH THE COMMISSION PURSUANT TO RULE 24b-2.] 2.3.4 First Right to Reverted Chemical Classes. If, during the term of this Agreement, a Compound contained within a Chemical Class that has reverted to Shaman pursuant to Section 2.3.3 is the subject of an IND filing or equivalent for the initiation of human clinical trials, Shaman shall promptly inform LIPHA in writing and deliver to LIPHA a summary of the preclinical data generated for such Compound. LIPHA shall thereafter have the option, exercisable for a period of * * * days following the delivery of such information, to designate such Compound as a Lead Compound subject to the terms and conditions of this Agreement, in exchange for the payment to Shaman of a lump sum in cash equal to (i) Two Million Seven Hundred Thousand dollars ($2,700,000) (the aggregate pre-clinical milestones payments that would have otherwise become due and payable under Section 4.2.1 below), plus (ii) any clinical milestones due pursuant to Section 4.2.3; reduced in each case by any milestone payments already made by LIPHA with respect to the same Chemical Class pursuant to Section 4.2. In the event LIPHA fails to exercise its option within the * * * day period prescribed above, Shaman shall thereafter be free to itself develop Compound(s) within such Chemical Class or license to a third party the rights to commercialize Compound(s) within such Chemical Class in the Territory, subject only to Sections 2.3.5 and 2.3.6 below. [* INDICATES THAT MATERIAL HAS BEEN OMITTED AND CONFIDENTIAL TREATMENT HAS BEEN REQUESTED THEREFOR. ALL SUCH OMITTED MATERIAL HAS BEEN FILED SEPARATELY WITH THE COMMISSION PURSUANT TO RULE 24b-2.] 2.3.5 Second Right to Reverted Chemical Classes . If, during the term of this Agreement, a Compound contained within a Chemical Class that has reverted to Shaman pursuant to Section 2.3.3 has received clearance for the initiation of human clinical trials, Shaman shall promptly inform LIPHA in writing and deliver to LIPHA a summary of the preclinical data generated for such Compound. LIPHA, in turn, shall have the right to conduct limited human clinical testing of such Compound pursuant to a protocol approved in writing by both Parties. If LIPHA notifies Shaman in writing of LIPHA's interest in incorporating such Compound and its Chemical Class in the Collaboration within one year of the notification by Shaman to LIPHA of the clearance to initiate clinical trials of such Compound, then LIPHA shall be entitled to incorporate such Compound and its Chemical Class in this Collaboration by making a lump sum cash payment to Shaman equal to (i) Three Million Nine Hundred Thousand dollars ($3,900,000) plus (ii) any clinical milestones that may have become due pursuant to Section 4.2.3; reduced in each case by any milestone payments already made by LIPHA with respect to the same Chemical Class pursuant to Section 4.2. Notwithstanding the foregoing, this second right to reverted Compounds shall only be available to LIPHA if LIPHA has purchased (or committed in connection with its receipt of the option set forth in this Section 2.3.5 to purchase) at least $3,500,000 in equity value (or 350,000 shares, as adjusted for stock splits and recapitalizations, whichever is less) in the next public offering, if any, conducted by Shaman after the date of this Agreement. 2.3.6 Final Right to Reverted Chemical Classes . With respect to any reverted Chemical Class, if following the expiration of the rights granted in subsections 2.3.4 and 2.3.5 above, Shaman desires to enter into a corporate licensing arrangement and outlicense any Compound, Shaman shall so notify LIPHA in writing and then Shaman will allow LIPHA * * * ( * ) days after receipt of such written notice to negotiate in good faith a license to such Compound with Shaman. If during such * * * ( * ) day period, the Parties have failed to reach full agreement on the license terms for such agreement, Shaman shall be free to conclude an agreement with a third party for such Compound on terms not materially more favorable, as a whole, to such third party, than those refused by LIPHA. [* INDICATES THAT MATERIAL HAS BEEN OMITTED AND CONFIDENTIAL TREATMENT HAS BEEN REQUESTED THEREFOR. ALL SUCH OMITTED MATERIAL HAS BEEN FILED SEPARATELY WITH THE COMMISSION PURSUANT TO RULE 24b-2.] 2.4 Joint Obligations. During the Research Period and thereafter during the term of this Agreement, LIPHA and Shaman shall inform each other, to the extent they have not already done so, of their respective Technical Information that is necessary or useful for the other Party to carry out its obligations under this Agreement, to achieve the goals of the Collaboration or to develop, manufacture, register, market and sell Products. During the term of this Agreement, each Party will permit access at reasonable times and with reasonable frequency to the relevant scientific, manufacturing, preclinical, clinical, regulatory and other appropriate personnel of the other Party. Each Party will, not less frequently than at each meeting of the Joint Research and Development Steering Committee, (i) provide the other party with a progress report on its efforts and results on the Collaboration, and (ii) inform the other Party of any Technical Information (including all pre-clinical and clinical results relating to the Products) obtained by them to the extent such results are necessary or useful for the other Party to carry out its obligations under this Agreement, to achieve the goals of the Collaboration or to develop, manufacture, register, market and sell Products. 2.5 Joint Research and Development Steering Committee and Joint Clinical Development Committee. Promptly following the Effective Date, Shaman and LIPHA shall each appoint two (2) representatives to a Joint Research and Development Steering Committee. Upon the commencement of human clinical trials with respect to any Product, the Party initiating such trials shall be responsible for creating a two (2) party or a three (3) party (depending on whether Ono is also developing the same Compound in clinical trials) Joint Clinical Development Committee and Shaman, LIPHA and Ono, as applicable, shall each appoint two (2) representatives to such Joint Clinical Development Committee. Together, the Joint Research and Development Steering Committee and the Joint Clinical Development Committee shall be referred to as the "Committees." All members of the Committees shall be senior executive officers of the relevant Party, vested with final decision making authority with respect to the Collaboration. Subject to the foregoing, each Party may change any of its representatives at any time and from time to time by written notice to the other Party prior to appointing a new representative to the applicable Committee. The memberships of the Committees may include individuals serving on both Committees. 2.6 Meetings of the Committees. The Committees shall meet every three (3) months, unless otherwise mutually agreed. The Chief Executive Officer of each of the Parties shall attend together one (1) meeting each of the Committees each year. Such meetings shall take place at sites which shall be designated by each of the Parties in alternating sequence. Each Party shall pay its own costs in attending Committee meetings. Executive officers from Shaman or LIPHA may attend such meetings with the consent of the relevant Committee. A hosting Party shall designate a member to act as Chairman of the Committee meetings. Each such Chairman shall be responsible for developing an agenda and supporting materials for the meeting, and shall distribute such agenda no later than fourteen (14) days prior to the scheduled meeting. The Chairman shall promptly, after each meeting, prepare and distribute to the members minutes reflecting the discussions of the Committee, which minutes shall be subject to the review and approval of such Committee at the next meeting thereof. All meetings shall be conducted and records kept in English. In the event that either Committee is unable to resolve any disagreement, either Party shall use commercially reasonable and diligent efforts to resolve the dispute amicably. Any dispute that the Parties are unable to resolve by good faith negotiation shall be subject to the dispute resolution mechanism prescribed in Section 10. 3 DEVELOPMENT PHASE; MANAGEMENT; DEVELOPMENT PLAN; REGULATORY MATTERS. 3.1 Development Collaboration. Each Product will be developed for use in the Field pursuant to this Section 3. The role of each Party in the development program for each Product shall be determined by this Section 3, with each Party having the authority described in Section 3.2 and providing advisory services with respect to each phase of the process in which such Party does not have primary responsibility. 3.2 Development Plan. 3.2.1 Within * * * months from the date a Lead Compound is first selected, LIPHA shall establish and present to Shaman for its review and comment a development plan including budgeting information for each Lead Compound with respect to the preclinical and clinical development and regulatory approval of such Lead Compound for use in the Field (the "Development Plan"). Depending on the state of development of the Lead Compound, the Development Plan shall describe fully the proposed program of development for each Lead Compound, including pre-clinical testing, formulation, process development, manufacture of pilot and clinical trial lots, clinical studies and regulatory plans and other key elements of obtaining Regulatory Approval in the Territory. LIPHA shall update the Development Plan annually, and oversee its implementation. [* INDICATES THAT MATERIAL HAS BEEN OMITTED AND CONFIDENTIAL TREATMENT HAS BEEN REQUESTED THEREFOR. ALL SUCH OMITTED MATERIAL HAS BEEN FILED SEPARATELY WITH THE COMMISSION PURSUANT TO RULE 24b-2.] 3.2.2 In the event that the Parties are unable to agree on a specific protocol or the need to conduct specific clinical or pre-clinical studies, LIPHA's decisions shall control clinical and pre-clinical studies (including their protocols) for filing in the Territory (provided, however, that in the U.S. LIPHA shall consult with Shaman as to preclinical and clinical studies), and, as between the Parties, Shaman's decisions shall control clinical and pre-clinical studies (including their protocols) for filing in the Ono Territory; provided, that in no event will either Party take any action that will impair the other Party's efforts to have a Lead Compound achieve the relevant Regulatory Approvals. The Parties shall use their diligent efforts, through the two Committees, to coordinate their respective development plans and to create and maintain a single worldwide safety and adverse events database and shall share the results of the Parties' respective preclinical and clinical trials in order to facilitate such development by both Parties, including, when feasible, elimination of duplicate development efforts. Each Party shall immediately inform the other at such time as it receives notice of any Regulatory Approvals. 3.3 Development Efforts. Once a Compound has been selected as a Lead Compound, LIPHA shall use its commercially reasonable efforts to (i) develop, test and, where applicable, manufacture a Product based on such Lead Compound, including without limitation, pre-clinical and clinical development, (ii) obtain Regulatory Approvals in the Territory (it being understood that LIPHA would intend to first prepare a registration dossier for and initially seek Regulatory Approvals in the United States or one or more of the Major Market Countries) and (iii) subject to Section 5.2 below, market and sell the Product in the Territory. LIPHA shall provide Shaman with reports of its progress at each meeting of either Committee, or more frequently as Shaman may reasonably request. 3.4 Pre-Clinical and Clinical Matters.

LIPHA shall pay to Shaman each of the amounts set forth below, payable in the manner set forth in this Section 4.2, at or before the end of each period set forth below. 4.2.1 Pre-clinical Milestones. For each Chemical Class containing a Compound or Compounds: PRE-CLINICAL MILESTONE PAYMENT .1 *months after selection of such Chemical Class* $0.8 million .2 *months after selection of such Chemical Class* $0.9 million .3 *months after selection of such Chemical Class* $1.0 million [* INDICATES THAT MATERIAL HAS BEEN OMITTED AND CONFIDENTIAL TREATMENT HAS BEEN REQUESTED THEREFOR. ALL SUCH OMITTED MATERIAL HAS BEEN FILED SEPARATELY WITH THE COMMISSION PURSUANT TO RULE 24b-2.] In the event that LIPHA shall, pursuant to applicable law and regulation, administer any Lead Compound to a human in the course of its preclinical studies, then all Pre-clinical Milestones shall be paid in full immediately. 4.2.2 Supply of Compound during Pre-clinical Period. Shaman shall supply LIPHA with the following quantities of a Compound or Compounds within a Chemical Class during the Evaluation Period with respect to such Chemical Class: (i) 2.5 grams upon selection of a Lead Compound; (ii) at least 30 grams within the first twelve months (which shall be supplied (A) as rapidly as possible and (B) at a rate which at least equals 10 grams for each four month period and if not supplied at such rate, the 12 month period shall be correspondingly extended as described below in this Section and (iii) at least another 250 grams provided ratably over months 13-30. In the case of (ii) and (iii) in the foregoing sentence, Shaman shall use its commercially reasonable efforts to provide such additional quantities of each Compound as requested by LIPHA as soon as Shaman is able and all quantities of material supplied after the initial 32.5 grams shall be supplied at Shaman's direct cost for such materials, the initial 32.5 grams being supplied as part of the research payments made by LIPHA, and without further charge to LIPHA. For synthetic Compounds, Shaman will supply only the first 32.5 grams. In the event that LIPHA requests and Shaman is unable to supply sufficient quantities of such Compound or raw plant material for extraction thereof during such periods or LIPHA is unable despite good faith efforts to synthesize the specified quantities of Compound, then the applicable milestone time lines under paragraph 4.2.1 above shall be extended on a month-by-month basis during any period such supply requirements cannot be met, ---------- * Payment will be due in each case only if LIPHA is then still pursiuing the development of a Compound within the same Chemical Class a that first presented. Failure to make such payment shall be deemed a decision by LIPHA not to pursue such Chemical Class further and all rights therein shall revert to Shaman subject only to the reversion rights set forth in Sections 2.3.4, 2.3.5 and 2.3.6. thereby extending the Evaluation Period. LIPHA shall provide Shaman with reasonable lead time, considering Shaman's plant collection effort, with respect to any request hereunder for the delivery of any Compound, or raw plant material for extraction thereof, during the respective periods. 4.2.3 Clinical Milestones. For each Lead Compound being developed for an indication within the Field: CLINICAL MILESTONE PAYMENT .1 Upon commencement of Phase II Clinical Studies $1.5 million .2 Upon commencement of Phase III Clinical Studies $1.8 million .3 Upon the first filing of an NDA in the United States or equivalent filing in any Major Market Country $2.0 million .4 Upon the first Regulatory Approval in the United States or equivalent approval in any Major Market Country $2.5 million 4.2.4 Additionally, with respect to the milestones set forth in this Section 4.2, the following shall apply: .1 The milestones set forth in subsections 4.2.1.1, 4.2.1.2 and 4.2.1.3 and 4.2.3.1 shall be nonrefundable and nonrecoverable. .2 The milestones set forth in subsections 4.2.3.2, 4.2.3.3, and 4.2.3.4 shall be creditable against royalties owing to Shaman from LIPHA on account of sales of any Product in all countries in the Territory in years 2, 3 and 4 after initial commercialization, with one-third (1/3rd) of the aggregate creditable milestone amount being credited in each such year (in the event the amount of a credit exceeds the amount of royalties payable over such three year period, then such excess shall be carried forward into future years until it is fully recovered out of royalties). .3 With respect to any Chemical Class as to which LIPHA pays Shaman at least one milestone pursuant to this section 4.2, if the development of such Chemical Class is subsequently discontinued prior to commercialization solely as a result of the inability of Shaman or LIPHA to obtain patent protection in the U.S. or in any of the Major Market Countries for such Chemical Class for its use as a therapeutic, then LIPHA shall be entitled to credit such milestone(s) against the milestones owing to Shaman on the next Chemical Class chosen for development by LIPHA. .4 Each milestone payment may only be credited once against future liabilities owing from LIPHA to Shaman. .5 In addition, there shall be cap of $7.8 Million, on the crediting of milestones against any individual Product royalty amount. 4.3 Payment Terms. All payments under this Agreement shall be by wire transfer of immediately available funds to a bank account designated by Shaman at the time payment is due, or within forty-five days after receipt by LIPHA of the corresponding invoices for such payment from Shaman.

During the term of this Agreement, subject to reciprocity by Ono, Shaman and LIPHA shall make available, without charge, to Ono all of the LIPHA Technical Information and the Shaman Technical Information which is useful or necessary for registration, manufacture, use or sale of a Mutual Product, in whatever form is best suited to fully deliver such information, including, but not limited to, the transfer of copies of all issued patents, patent applications, technical information and data relating to Mutual Products (defined in Section 9.3 below). Each of the parties shall also provide the other parties with reports of its progress. 9.3 Global Development Plan; Coordination. In the event that Ono and LIPHA have each chosen to develop a therapeutic product for the Field derived from the same Compound in development and having substantially the same identity for marketing, sales or regulatory purposes (a "Mutual Product"), LIPHA, Shaman and Ono shall use their commercially reasonable and diligent efforts in mutual cooperation with one another to establish a Joint Clinical Development Committee pursuant to Section 2.5 and a development plan for such Mutual Product with respect to the pre-clinical and clinical studies of such Mutual Product (the "Global Development Plan"). Each party may use such study data for regulatory filing and approval purposes in their respective territory. In the event that the three parties are unable to agree on a specific protocol or the need to conduct specific clinical or pre-clinical studies, LIPHA's decisions shall control clinical and pre-clinical studies (including their protocols) for filing in the Territory, and Ono's decisions shall control clinical and pre-clinical studies (including their protocols) for filing in the Ono Territory; provided, that to the extent possible neither party will take an action that will impair the others' efforts to have a Mutual Product achieve the relevant Regulatory Approvals. In addition, the three parties shall create and maintain a single worldwide database regarding safety and adverse clinical events and any other clinical data as may be required by the appropriate regulatory agencies, and shall promptly share with each other the results of the parties' respective pre-clinical and clinical studies. 10. DISPUTE RESOLUTION AND ARBITRATION. 10.1 Initial Resolution Mechanisms. The Parties recognize that disputes as to certain matters may from time to time arise during the term of this Agreement which relate to either Party's rights and/or obligations hereunder. It is the objective of the Parties to establish procedures to facilitate the resolution of disputes arising under this Agreement in an expedient manner by mutual cooperation and without resort to litigation. To accomplish this objective, the Parties agree to follow the procedures set forth in this Section 10, if and when a dispute arises under this Agreement, which dispute cannot be resolved as set forth in Section 2.6 above. If the Parties are unable to resolve such a dispute within thirty (30) days, either Party may, by written notice to the other, have such dispute referred to their respective chief executive officers, for attempted resolution by good faith negotiations within fourteen (14) days after such notice is received. In the event the designated executive officers are not able to resolve such dispute, either Party may at anytime after the fourteen (14) day period invoke the provisions of Section 10.2. 10.2 Arbitration. The parties agree that any dispute, controversy or claim (except as to any issue relating to intellectual property owned in whole or in part by Shaman or LIPHA) arising out of or relating to this Agreement, or the breach, termination or invalidity thereof, shall be resolved through negotiation and/or binding arbitration. If a dispute arises between the parties, and if said dispute cannot be resolved pursuant to Section 10.1, the Parties agree to resolve by binding arbitration in accordance with the rules of the International Chamber of Commerce ("I.C.C."), except as modified herein. Shaman and LIPHA shall each select one arbitrator and the two arbitrators so selected shall choose a third arbitrator to resolve the dispute. The arbitration shall be held in New York City, New York, and the decision shall be rendered within three (3) months of conclusion of arbitration and shall be binding and not be appealable to any court in any jurisdiction. The arbitration shall determine the share of the cost of the arbitration filing and hearing fees and the cost of the arbitrators. Each party must bear its own attorney's fees and associated costs and expenses. 10.3 Jurisdiction. For the purposes of this Section 10, the Parties agree to accept the jurisdiction of the federal courts located in the Southern District (New York City) of New York for the purposes of entering the decision rendered by any arbitration panel and enforcing awards entered pursuant to, and for enforcing the agreements reflected in, this Article. 10.4 Determination of Patents and Other Intellectual Property. Any dispute relating to the determination of validity of a Party's Patents or other issues relating solely to a Party's intellectual property shall be submitted exclusively to the federal or national court located in the location of the defendant, and the Parties hereby consent to the jurisdiction and venue of such court. 11. CONFIDENTIALITY, DISCLOSURE AND PUBLICATION. 11.1 Prior Agreements. This Agreement supersedes any and all previous agreements and understandings, whether oral or written, between the Parties regarding the treatment of confidential information. 11.2 Confidentiality. During the term of this Agreement and thereafter, each Party shall maintain in confidence all information and materials disclosed by the other Party and marked as confidential or which such Party knows or has reason to know are or contain trade secrets or other proprietary information of the other, including without limitation, information relating to the Technical Information of the other Party, Joint Inventions and inventions of the other Party, and the business plans of the other Party, including information provided by either Party to the other Party prior to or after the Effective Date, and shall not use such trade secrets, information or materials for any purpose except as permitted by this Agreement or disclose the same to anyone other than those of its Affiliates, sublicensees, employees, consultants, agents or subcontractors as are necessary in connection with such Party's activities as contemplated in this Agreement. Each Party shall obtain a written agreement from any sublicensees, employees, consultants, agents and subcontractors, prior to disclosure, to hold in confidence and not make use of such trade secrets or proprietary information for any purpose other than those permitted by this Agreement. 11.3 Exceptions. 11.3.1 The obligation of confidentiality contained in this Agreement shall not apply to the extent that (a) either Party (the "Recipient") is required to disclose information by order or regulation of a governmental agency or a court of competent jurisdiction, provided that the Recipient shall not make any such disclosure (other than a filing of information or materials with (i) the U.S. Securities and Exchange Commission; (ii) a similar filing of information or materials with the National Association of Securities Dealers; or (iii) state securities regulations or a filing of information or materials pursuant to the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended and the rules and regulations thereunder, as amended; or (iv) a filing with the Commission des Operations de Bourse and other corresponding French or German or other European agencies) without first notifying the other Party and allowing the other Party a reasonable opportunity to seek injunctive relief from (or protective order with respect to) the obligation to make such disclosure or (b) the Recipient can demonstrate that (i) the disclosed information was at the time of such disclosure to the Recipient already in (or thereafter enters) the public domain other than as a result of actions of the Recipient, its Affiliates, employees, sublicensees, agents or subcontractors in violation hereof; (ii) the disclosed information was rightfully known by the Recipient or its Affiliates (as shown by its written records) prior to the date of disclosure to the Recipient in connection with the negotiation, execution or performance of this Agreement; or (iii) the disclosed information was received by the Recipient or its Affiliates on an unrestricted basis from a source unrelated to any Party to this Agreement and not under a duty of confidentiality to the other Party or (c) disclosure is made to a government regulatory agency as Part of such agency's product license approval process. 11.3.2 In the event that Ono chooses to develop a product for the treatment of Diabetes based on a Compound that has been selected by LIPHA as a Lead Compound, the obligation of confidentiality shall be waived by LIPHA with respect to all pre-clinical and clinical data with respect to such Compound generated by LIPHA in the course of its product development efforts. As a condition to such disclosure, Shaman has required Ono to enter into confidentiality provisions equivalent to those set forth in this Section 11. Shaman's agreement with Ono contains a provision equivalent in substance requiring Ono to disclose to LIPHA pre-clinical and clinical data generated by Ono. 11.4 Publications. Prior to public disclosure or submission for publication of a manuscript describing the results of any aspect of the Collaboration or other scientific or clinical activity or collaboration between LIPHA and Shaman or their Affiliates, the Party disclosing or submitting such a manuscript ("Disclosing Party") shall send the other Party ("Responding Party") a copy of the manuscript to be submitted and shall allow the Responding Party not less than sixty (60) days in which to determine whether the manuscript contains subject matter for which patent protection should be sought prior to publication of such manuscript for the purpose of protecting an invention of commercial value to the Responding Party, or whether the manuscript contains confidential information belonging to the Responding Party. After the expiration of such sixty (60) day period, if the Responding Party has not objected, the Disclosing Party may submit such manuscript for publication and publish or otherwise disclose to the public such research results. If the Responding Party believes the subject matter of the manuscript contains confidential information or a patentable invention of commercial value to the Responding Party, then prior to the expiration of such sixty (60) day period, the Responding Party shall notify the Disclosing Party in writing of its determination. Upon receipt of such written notice from the Responding Party, the Disclosing Party shall delay public disclosure of such information or submission of the manuscript for an additional period of thirty (30) days to permit preparation and filing of a patent application on the disclosed subject matter. The Disclosing Party shall thereafter be free to publish or disclose such information, except that the Disclosing Party may not disclose any confidential information of the Responding Party in violation of this Section 11 without the prior written consent of the Responding Party. Determination of authorship for any paper or patent shall be in accordance with accepted scientific practice. Should any questions on authorship arise, this will be determined by good faith consultation between the members of the Joint Research and Development Steering Committee as appropriate. 12. INDEMNIFICATION. Each Party shall defend, indemnify and hold the other Party, any officer, director or employee of such other Party or any of its Affiliates (individually, an "Exculpated Party") harmless from and against any damage, loss, liability or expense (including, without limitation, reasonable attorneys' fees, settlement costs, litigation costs and costs on appeal regardless of outcome) incurred or suffered by any Exculpated Party arising out of (i) any misrepresentation or breach of warranty made by such Party pursuant to this Agreement or (ii) any claim arising from the negligence or intentional misconduct of any of such Party's employees or agents and specifically for any claim of any kind whatsoever arising from the testing, manufacture, use, sale, consumption, distribution or advertising of any of the Products which may be developed as a result of this Agreement. 12.1 Each Party shall advise the other in writing promptly upon becoming aware of any adverse event(s) arising out of any use of the Compound or the Products, whether for commercial or noncommercial use. 12.2 Either Party (the "Notifying Party") shall promptly notify the other Party (the "Indemnifying Party") of the existence of any third party claim, demand or other action giving rise to a claim for indemnification under this Agreement (a "Third Party Claim") and shall give the Indemnifying Party a reasonable opportunity to defend the same at its own expense and with its own counsel, provided that the Notifying Party shall at all times have the right to participate in such defense at its own expense. If, within a reasonable time after receipt of notice of a Third Party Claim, the Indemnifying Party shall fail to undertake to so defend, the Notifying Party shall have the right, but not the obligation, to defend and to compromise or settle (exercising reasonable business judgment) the Third Party Claim for the account and at the risk and expense of the Indemnifying Party. Each Party shall make available to the other at the other's expense such information and assistance as the other shall reasonably request in connection with the defense of a Third Party Claim. 13. INDEPENDENT CONTRACTORS. Both Parties shall act solely as independent contractors and nothing in this Agreement shall be construed to give either Party the power or authority to act on behalf of the other and each party shall hold the other party harmless against any claim based on a representation of authority in excess of that provided herein, provided that the indemnitor is given prompt notice of any such claim, loss or liability and has the right to participate in, and at its own option control, any proceeding arising therefrom. 14. NO SOLICITATION OF EMPLOYEES. During the term of this Agreement and for two (2) years thereafter, neither Party shall solicit the other's employees without the prior written approval of the other Party. This provision will not preclude any Party from hiring any such employees if they independently apply for a job without solicitation or pursuant to a general solicitation not specifically directed at such employee. 15. TERM. This Agreement shall become effective as of the Effective Date first written above and, unless sooner terminated pursuant to the provisions of Section 16 below, shall remain in full force and effect for so long as LIPHA shall be obligated to make royalty payments to Shaman pursuant to Section 8.4. LIPHA shall after the expiration of this Agreement (other than any termination by Shaman under Section 16) have the right to manufacture and sell any Products as to which royalty obligations have expired in accordance with Section 8.4, i.e. later of ten years after commercialization or expiration of patents, without any further obligation of paying royalties. 16. TERMINATION OF AGREEMENT. 16.1 This Agreement shall be terminable in its entirety by mutual written agreement of both Parties. 16.2 This Agreement shall be terminable at the option of either Party upon written notice to the other, if such other Party is in material breach or default with respect to any material term or provision hereof and fails to cure the same within sixty (60) days after written notice of said breach or default. Such termination rights shall be in addition to and not in substitution of any other remedies that may be available to the Party serving such notice against the Party in default. Termination pursuant to this Section 16.2 shall not relieve the Party in default from liability and damages to the other Party for breach of this Agreement. 16.3 This Agreement shall be terminable at the option of either Party upon written notice to the other, if such other Party is adjudged bankrupt, files or has filed against it any petition under any bankruptcy, insolvency or similar law, which petition is not dismissed within sixty (60) days, has a receiver appointed for its business or property, or makes a general assignment for the benefit of its creditors. 16.4 LIPHA shall have the right, at its sole discretion, to terminate this Agreement if within two (2) years following the Effective Date, no human clinical studies have been commenced for any Compound for an indication in the Field. Such right of termination shall be exercised within a period of ninety (90) days following the second anniversary of the Effective Date, and by LIPHA giving to Shaman sixty (60) days advance written notice of such termination. In the event of such termination, LIPHA shall have no obligation to make any further payments to Shaman under this Agreement (or to purchase additional shares under the Stock Purchase Agreement, it being nevertheless understood that the Registration Rights Agreement shall continue to apply to any and all shares of Common Stock already purchased, at that date, by LIPHA pursuant to the Stock Purchase Agreement), nor shall Shaman be entitled to any indemnity, damages or other payment, it being understood that LIPHA shall then have no further rights hereunder, whether to Compounds already selected, in development, or otherwise. 16.5 In the event of any acquisition or merger of Shaman by or with a third party in which Shaman is not the surviving entity, if such third party is a direct competitor of LIPHA in the Field, LIPHA shall be entitled to terminate this Agreement as a result of such merger or acquisition, provided that LIPHA shall have the right to retain all Product and technology rights licensed to LIPHA at the time of such termination subject to all applicable milestone and royalty payments and other LIPHA obligations relating to such licensed rights. 17. PUBLIC ANNOUNCEMENT OF AGREEMENT. Except as required to comply with U.S. and other foreign securities laws, any order of a court or government agency of any country of the Territory, and except as provided below, neither Party shall release information concerning this Agreement or the subject matter hereof to the news media, or other media, without first sending the other Party by express mail or facsimile, a copy of the information to be disclosed and allowing the other Party a reasonable time (not to exceed three (3) business days from the date of receipt) in which to comment on the information. If the other Party objects to the information to be disclosed and prior to the expiration of the three (3) business day period, the other Party shall so notify the disclosing Party who shall then delay public disclosure of the information and make reasonable efforts to accommodate any request for revisions by the other Party. If no notification is received during the three (3) business day period, the Party proposing disclosure shall be free to disclose the information. The Parties designate the following individuals to receive and approve announcements under this provision: Shaman, its Chief Executive Officer; LIPHA, its Chairman and Chief Executive Officer. The Parties agree that Shaman may discuss the general terms of the Agreement with Ono without disclosing any Confidential Information of LIPHA or LIPHA Technical Information without LIPHA's prior written consent; and that the parties will cooperate in good faith with one another to formulate a form of announcement that Shaman and LIPHA may release as soon as practicable after the Effective Date. 18. PATENT MATTERS. The ownership rights and other matters regarding patents developed pursuant to the Collaboration pursuant to this Agreement shall be as follows: 18.1 Inventions; Joint Inventions and Patents. 18.1.1 Ownership of all inventions arising during the term of the Research Period and for a period of five (5) years thereafter that are either (i) related to Compounds or any modification or improvement of such Compounds, or (ii) substantially similar in structure or site of activity to Compounds or any modification or improvement of such Compounds (except those that LIPHA can clearly demonstrate are independently developed by LIPHA as evidenced by written records), whether patented or not, which are invented by LIPHA or its Affiliates or a person contractually required to assign or license patent rights covering such inventions to LIPHA, shall be vested jointly in Shaman and LIPHA or their respective Affiliates consistent with the United States laws pertaining to joint ownership of patents and inventions ("Joint Inventions"). 18.1.2 In the event that during the term of the Research Period and the period of five (5) years thereafter, Shaman becomes aware of an invention that it believes should be treated as a Joint Invention pursuant to Section 18.1.1 and is not being treated as such by LIPHA, Shaman shall have the opportunity to receive a reasonably detailed scientific presentation by LIPHA on such invention to determine in good faith whether such invention should be treated as a Joint Invention. Shaman and LIPHA shall retain full ownership to all Joint Inventions and any Patents resulting therefrom, with full ownership rights in any field and subject only to the licenses granted in Section 8, with the full right by either party to transfer joint ownership in or to sublicense any such Joint Invention or Patent without the consent of the other party and without accounting to the other party for any consideration received from such transfer of joint ownership or sublicense. The laws of the United States with respect to joint ownership of inventions shall, to the extent not inconsistent with the foregoing sentence, apply in all jurisdictions giving force and effect to this Agreement. All information provided by either party in the course of such a presentation shall be subject to the confidentiality provisions of Section 11 hereof. 18.1.3 Except as otherwise expressly set forth in this Agreement, ownership of all sole inventions of either Party hereto shall be vested solely in that Party. 18.2 General Provisions Relating to Prosecution and Maintenance. Both Parties shall jointly file patent applications for Joint Inventions made by the Parties. Joint applications shall be filed initially in the United States, unless the Joint Research and Development Steering Committee determines for a compelling business reason that the application should first be filed in another jurisdiction. 18.3 Payments; Disputes. With respect to Shaman Patents, Shaman shall bear all costs and expenses for fees or other payments required to submit and maintain their own applications and patents in the whole world. With respect to LIPHA Patents, LIPHA shall bear all costs and expenses for fees or other payments required to submit and maintain their own applications and patents in the whole world. With respect to Joint Patent application filings, Shaman and LIPHA shall share all costs and expenses for fees or other payments required to submit and maintain joint applications and patents in the Territory. In the event there is a dispute as to whether a particular invention was developed by a Party individually or by the Parties jointly, the issue shall be resolved by the Joint Research and Development Steering Committee. 18.4 Infringement by a Third Party. If at any time either Party hereto shall become aware of any infringement or threatened infringement by a third party in the Territory of any or all of the Shaman Patents, LIPHA Patents or Joint Patents to which the Party having the knowledge thereof claims an interest pursuant to this Agreement, the Party having the knowledge thereof shall forthwith give notice thereof to the other Party. Upon notice of any such infringement, the Parties shall promptly consult with one another with a view toward reaching agreement on a course of action to be pursued. 18.4.1 Shaman shall have the first right but not the obligation to bring an enforcement action or to take any other reasonable steps to defend Shaman Patents and Joint Patents against infringement and LIPHA shall in such event give all reasonable assistance to Shaman with respect to patent and legal questions. The costs of such patent enforcement shall be borne by Shaman. If Shaman does not commence a particular infringement action within ninety (90) days after it has received notice of such infringement, LIPHA, after notifying Shaman in writing, shall be entitled to bring such infringement action or other appropriate action or claim at its own expense but shall request in writing that Shaman fund 50% of such expenses. The party conducting such action shall consider in good faith the comments of the other party with regard to the conduct of such action. If Shaman declines to pursue such action or fails to respond to LIPHA within 60 days after receipt of LIPHA's notice that it will do so and LIPHA undertakes such action, then LIPHA shall be entitled to 100% of all recoveries and LIPHA shall no longer be required to pay royalties to Shaman for any Product covered by such patent(s) in the country in which such action was prosecuted. Recovery from any settlement or judgement from any such action in the Territory either pursued by Shaman or co-funded by Shaman shall go first to reimburse the expenses of the parties and the remainder shall be shared by the parties on a 50%/50% basis. Notwithstanding the foregoing, if the monetary recovery is less than the out-of-pocket expenses of Shaman and LIPHA, reimbursement shall be on a pro rata basis, based upon cost incurred. In any event, Shaman and LIPHA shall assist one another and reasonably cooperate in any such litigation at the other's request without expense to the requesting party. 18.4.2 LIPHA shall have the first right but not the obligation to bring an enforcement action or to take any other reasonable steps to defend LIPHA Patents against infringement and Shaman shall in such event give all reasonable assistance to LIPHA with respect to patent and legal questions. The costs of such patent enforcement shall be borne by LIPHA but Shaman shall have the right to co-fund 50% of the expenses. If LIPHA does not commence a particular infringement action within ninety (90) days after it has received notice of such infringement, Shaman, after notifying LIPHA in writing, shall be entitled to bring such infringement action or other appropriate action or claim at its own expense but shall request in writing that LIPHA fund 50% of such expenses. The party conducting such action shall consider in good faith the comments of the other party with regard to the conduct of such action. If LIPHA declines to pursue such action or fails to respond to Shaman within 60 days after receipt of Shaman's notice that it will do so, Shaman undertakes such action and LIPHA fails to fund 50% of Shaman's expenses in pursuing such action, then Shaman shall be entitled to 100% of all recoveries. If LIPHA notifies Shaman that it will pursue and does pursue such action and Shaman declines to co-fund the same or fails to notify to LIPHA within 60 days after receipt of LIPHA's notice that it will pursue the action, then LIPHA shall be entitled to 100% of all recoveries and LIPHA shall no longer be required to pay royalties to Shaman for any Product covered by such patent(s) in the country in which such action was prosecuted. Recovery from any settlement or judgement from any such action in the Territory co-funded by the parties shall go first to reimburse the expenses of the parties and the remainder shall be shared by the parties on a 50%/50% basis. Notwithstanding the foregoing, if the monetary recovery is less than the out-of-pocket expenses of Shaman and LIPHA, reimbursement shall be on a pro rata basis, based upon cost incurred. In any event, Shaman and LIPHA shall assist one another and reasonably cooperate in any such litigation at the other's request without expense to the requesting party. 18.4.3 If Shaman and LIPHA, after consultation with each other, elect not to bring suit, individually or jointly, or if Shaman and/or LIPHA, as the case may be, are/is not able to stop such infringing activities, the applicable royalty shall be adjusted as set forth in Section 8.4.1, if at all. 18.5 Alleged Infringement by Products. In the event of dispute concerning a third party's patent rights in the Territory, Shaman and LIPHA will proceed as follows: 18.5.1 While a dispute concerning infringement of a third party's patent rights is in progress, the Party which had a claim brought against it by a third party (the "Defendant Party") will use its best efforts to defend against the infringement claim and resolve the dispute; and both parties shall share all costs, fees and expenses associated with the resolution of this dispute. Additionally, the other Party will assist and use its best efforts to help the Defendant Party resolve the dispute on favorable terms, also sharing all such costs and expenses. 18.5.2 In the event the dispute is resolved against Shaman and/or LIPHA, with a finding of an infringement, then the Parties shall share all damages; and provided further that if any royalties are required to be paid to a third party as a result of such infringement or any negotiated settlement approved jointly by the Parties, then LIPHA shall make such payment and shall be entitled to deduct fifty percent (50%) of such payment against any royalties owing to Shaman under this Agreement. 19. RESEARCH EXPENSES. Except as otherwise expressly provided by this Agreement, each Party shall bear its own internal research, development and regulatory costs. 20. REPRESENTATIONS AND WARRANTIES.

Legend. It is understood that the certificates evidencing the Common Stock may bear substantially the following legend: i. THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933.

("LIPHA"). RECITALS A. WHEREAS, the Company proposes to sell shares of its Common Stock to LIPHA pursuant to a Stock Purchase Agreement of even date (the "Purchase Agreement"). B. WHEREAS, by this Agreement, the Company and LIPHA desire to provide for certain registration rights as set forth herein. AGREEMENT NOW, THEREFORE, THE PARTIES AGREE AS FOLLOWS: 1. Registration Rights. 1.1. Definitions. For purposes of this Section 1: 1.1.1. The term "register", "registered", and "registration" refer to a registration effected by preparing and filing a registration statement in compliance with the Securities Act of 1933 (the "Act"), and the declaration or ordering of effectiveness of such registration statement; 1.1.2. The term "Registrable Securities" means the Common Stock purchased by LIPHA pursuant to the Purchase Agreement and any Common Stock of the Company issued as a dividend or other distribution with respect to, or in exchange for, such Common Stock; 1.1.3. The term "Form S-3" means such form under the Act or any successor thereto adopted by the Securities and Exchange Commission ("SEC") which permits incorporation of substantial information by reference to other documents filed by the Company with the SEC. 1.2. Requested Registration of Defined Sale 1.2.1. If the Company, at any time after September 23, 1998 (the "Lockup Expiration Date") receives a written request from LIPHA that the Company file a registration statement under the Act covering the registration of at least twenty-five percent (25%) of the Registrable Securities then outstanding, then the Company shall, subject to the limitations of subsection 1.2.2 and Section 1.6, effect as soon as practicable, and in any event shall use its best efforts to effect within 90 days of the receipt of such request, the registration under the Act of all Registrable Securities which LIPHA requests to be registered. 1.2.2. The Company is obligated to effect only one (1) such registration pursuant to this Section 1.2, and shall not be obligated to effect such registration during the period starting thirty (30) days prior to the Company's estimated filing of, and ending four (4) months following the effective date of, any other registration statement of the Company. 1.2.3. All expenses other than underwriting discounts and commissions incurred in connection with the single registration, filing or qualification permitted pursuant to this Section 1.2, including (without limitation) all registration, filing and qualification fees, printer's and accounting fees, fees and disbursements of counsel for the Company, and the reasonable fees and disbursements of one counsel for LIPHA shall be borne by the Company; provided, however, that the Company shall not be required to pay for any expenses of any registration proceeding begun pursuant to this Section 1.2 if the registration request is subsequently withdrawn at the request of LIPHA (in which case LIPHA shall bear such expenses). 1.3. Shelf Registration on Form S-3. If the Company, at any time after the Lockup Expiration Date, receives from LIPHA, a written request that the Company effect a shelf registration on Form S-3 with respect to all or a part of the Registrable Securities owned by LIPHA, the Company will: 1.3.1. As soon as practicable, effect such registration as would permit or facilitate the sale and distribution of all or such portion of LIPHA's Registrable Securities as are specified in such request; provided, however, that the Company shall not be obligated to effect any such registration, qualification or compliance, pursuant to this section 1.3: (i) if Form S-3 is not available for such offering by LIPHA; (ii) if LIPHA proposes to sell Registrable Securities and such other securities (if any) at an aggregate price to the public of less than $500,000; (iii) if the Company has, within the twelve (12) month period preceding the date of such request, already effected one registration on Form S-3 for LIPHA pursuant to this Section 1.3; or (iv) in any particular jurisdiction in which the Company would be required to qualify to do business or to execute a general consent to service of process in effecting such registration, qualification or compliance. 1.3.2. Subject to the foregoing, the Company shall file a registration statement covering the Registrable Securities and other securities so requested to be registered as soon as practicable after receipt of the request of LIPHA. All expenses incurred in connection with any registration requested pursuant to Section 1.3, including (without limitation) all registration, filing, qualification, printer's and accounting fees and the reasonable fees and disbursements of counsel for LIPHA and counsel for the Company, but excluding any underwriters' discounts or commissions associated with Registrable Securities, shall be borne by Company. Registrations effected pursuant to this Section 1.3 shall not be counted as demands for registration or registrations effected pursuant to Sections 1.2. 1.4. Participation in Company Registrations. If the Company proposes to register any of its stock or other securities under the Act in connection with the public offering of such securities solely for cash (other than (i) a registration pursuant to a demand registration right held by any other stockholder of the Company; (ii) a registration relating solely to the sale of securities to participants in a Company stock plan; or (iii) a registration on any form which does not include substantially the same information as would be required to be included in a registration statement covering the sale of the Registrable Securities), the Company shall, at such time, promptly give LIPHA written notice of such registration. Upon the written request of LIPHA given within twenty (20) days after mailing of such notice by the Company, the Company shall, subject to the provisions of Section 1.5, cause to be registered under the Act all of the Registrable Securities that LIPHA has requested to be registered. 1.5. Underwriting Requirements. In connection with any offering involving an underwriting of shares of the Company's capital stock, the Company shall not be required under Section 1.4 to include any of LIPHA's securities in such underwriting unless LIPHA accepts the terms of the underwriting as agreed upon between the Company and the underwriters selected by it (or by other persons entitled to select the underwriters), and then only in such quantity as the underwriters determine in their sole discretion will not jeopardize the success of the offering by the Company. If the total amount of securities, including Registrable Securities, requested by shareholders to be included in such offering exceeds the amount of securities sold other than by the Company that the underwriters determine in their sole discretion is compatible with the success of the offering, then the Company shall be required to include in the offering only that number of such securities, including Registrable Securities, which the underwriters determine in their sole discretion will not jeopardize the success of the offering (the securities so included to be apportioned pro rata among the selling shareholders according to the total amount of securities entitled to be included therein owned by each selling shareholder or in such other proportions as shall mutually be agreed to by such selling shareholders). 1.6. Right to Defer. Notwithstanding Sections 1.2 and 1.3 above, if the Company shall furnish to LIPHA a certificate signed by the President of the Company stating that in the good faith judgment of the Board of Directors of the Company, it would be seriously detrimental to the Company and its shareholders for either form of such registration statement to be filed and it is therefore essential to defer the filing of such registration statement, the Company shall have the right to defer taking action with respect to such filing for a period of not more than 90 days after receipt of LIPHA's request; provided, however, that the Company may not utilize this right more than once in any twelve month period. 1.7. Obligations of the Company. Whenever required under this Section 1 to effect the registration of any Registrable Securities, the Company shall, as expeditiously as reasonably possible: 1.7.1. Prepare and file with the SEC a registration statement with respect to such Registrable Securities and use its best efforts to cause such registration statement to become effective, and, upon the request of LIPHA, keep such registration statement effective for up to one hundred twenty (120) days. 1.7.2. Prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection with such registration statement as may be necessary to comply with the provisions of the Act with respect to the disposition of all securities covered by such registration statement. 1.7.3. Furnish to LIPHA such numbers of copies of a prospectus, including a preliminary prospectus, in conformity with the requirements of the Act, and such other documents as it may reasonably request in order to facilitate the disposition of Registrable Securities owned by it. 1.7.4. Use its best efforts to register and qualify the securities covered by such registration statement under such other securities laws of such jurisdictions as shall be reasonably requested by LIPHA, provided that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in any such states or jurisdictions. 1.8. Furnish Information. It shall be a condition precedent to the obligations of the Company to take any action pursuant to this Section 1 with respect to the Registrable Securities of LIPHA that LIPHA shall furnish to the Company such information regarding itself, the Registrable Securities held by it, and the intended method of disposition of such securities as shall be required to effect the registration of LIPHA's Registrable Securities. 1.9. Indemnification. In the event any Registrable Securities are included in a registration statement under this Section 1: 1.9.1. To the extent permitted by law, the Company will indemnify and hold harmless LIPHA and each person, if any, who controls LIPHA within the meaning of the Act or the Securities Exchange Act of 1934, as amended (the "1934 Act"), against any losses, claims, damages, or liabilities (joint or several) to which they may become subject under the Act, or other federal or state law, insofar as such losses, claims, damages, or liabilities (or actions in respect thereof) arise out of or are based upon any of the following statements, omissions or violations (collectively a "Violation"): (i) any untrue statement or alleged untrue statement of a material fact contained in such registration statement, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto; (ii) the omission or alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements therein not misleading; or (iii) any violation or alleged violation by the Company of the Act, the 1934 Act, any state securities law or any rule or regulation promulgated under the Act, or any state securities law. The Company will pay to LIPHA or controlling person any legal or other expenses reasonably incurred by them (such payment to be made as incurred by such persons) in connection with investigating or defending any such loss, claim, damage, liability, or action; provided, however, that the indemnity agreement contained in this subsection 1.9.1 shall not apply to amounts paid in settlement of any such loss, claim, damage, liability, or action if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld), nor shall the Company be liable in any such case for any such loss, claim, damage, liability, or action to the extent that it arises out of or is based upon a Violation which occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by LIPHA or controlling person. 1.9.2. To the extent permitted by law, LIPHA will indemnify and hold harmless the Company, each of its directors, each of its officers who has signed the registration statement, and each person, if any, who controls the Company within the meaning of the Act, against any losses, claims, damages, or liabilities (joint or several) to which any of the foregoing persons may become subject, under the Act, or other federal or state law, insofar as such losses, claims, damages, or liabilities (or actions in respect thereto) arise out of or are based upon any Violation, in each case to the extent (and only to the extent) that such Violation occurs in reliance upon and in conformity with written information furnished by LIPHA expressly for use in connection with such registration; and LIPHA will pay any legal or other expenses reasonably incurred by any person intended to be indemnified pursuant to this subsection 1.9.2 (such payment to be made as incurred by such persons), in connection with investigating or defending any such loss, claim, damage, liability, or action; provided, however, that the indemnity agreement contained in this subsection 1.9.2 shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of LIPHA, which consent shall not be unreasonably withheld; provided that in no event shall any indemnity under this subsection 1.9.2 exceed the gross proceeds from the offering received by LIPHA, unless such Violation by LIPHA is wilful. 1.9.3. Promptly after receipt by an indemnified party under this Section 1.9 of notice of the commencement of any action (including any governmental action), such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Section 1.9, deliver to the indemnifying party a written notice of the commencement thereof and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party (together with all other indemnified parties which may be represented without conflict by one counsel) shall have the right to retain one separate counsel, with the fees and expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such proceeding. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action, if prejudicial to its ability to defend such action, shall relieve such indemnifying party of any liability to the indemnified party under this Section 1.9, but the omission so to deliver written notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this Section 1.9. 1.10. Reports Under Securities Exchange Act of 1934. With a view to making available to LIPHA the benefits of Rule 144 promulgated under the Act and any other rule or regulation of the SEC that may at any time permit LIPHA to sell securities of the Company to the public without registration or pursuant to a registration on Form S-3, the Company agrees to: 1.10.1. Make and keep public information available, as those terms are understood and defined in SEC Rule 144, at all times after ninety (90) days after the effective date of the first registration statement filed by the Company for the offering of its securities to the general public; 1.10.2. Take such action, including the voluntary registration of its Common Stock under Section 12 of the 1934 Act, as is necessary to enable LIPHA to utilize Form S-3 for the sale of its Registrable Securities; and 1.10.3. File with the SEC in a timely manner all reports and other documents required of the Company under the Act and the 1934 Act. 1.11. Amendment of Registration Rights. Any provision of this Agreement may be amended and the observance thereof may be waived (either generally or in a particular instance and either retroactively or prospectively), only with the written consent of the Company and LIPHA. 1.12. Limitation of Registration Rights. LIPHA shall not be entitled to exercise any right provided for in Sections 1.2, 1.3 or 1.4 if, at such time, LIPHA is entitled to sell all of the shares of Company Common Stock then held by it without restriction or further registration. 2. Miscellaneous. 2.1. Governing Law. This Agreement shall be governed in all respects by the laws of the State of California as applied to transactions taking place between California residents and wholly within the State of California. 2.2.
