Since 1992, the Company has focused on medical uses for its materials, primarily for surgical repair markets, surgical adhesives and sealants, soft tissues augmentation, wound healing and tissue engineering, surgical adhesion barriers and drug delivery devices. The Company has also developed coating technology that can efficiently modify and improve the surface properties of more traditional implantable materials used in a variety of applications, including cardiovascular products and contact lenses. The Company's current products include SmartPlastic(TM) and ProNectin (R) F Cell Attachment Factor for growing human and animal cells. The Company was incorporated in Delaware on July 6, 1988. The Company's principal executive offices are located at 10655 Sorrento Valley Road, San Diego, California 92121; its telephone number is (619) 558-6064. RISK FACTORS An investment in the Shares offered hereby involves a high degree of risk. The following risk factors should be considered carefully in evaluating an investment in the Shares offered hereby. DEPENDENCE ON STRATEGIC PARTNERS In order to reduce the time and costs for developing and commercializing its potential products, the Company's strategy is to enter into arrangements with major medical or pharmaceutical companies with broad distribution capabilities in appropriate markets. There can be no assurance that the Company will be able to establish such strategic partnerships or licensing arrangements upon favorable terms and conditions, if at all. Additionally, these arrangements generally may be subject to termination under various circumstances, or solely at the discretion of the strategic partner without prior notice. Termination of such arrangements would have a material adverse effect on the Company's business and financial condition. Furthermore, this strategy may lead to multiple alliances regarding different product opportunities that are active at the same time. There can be no assurance that the Company will be able to successfully manage such multiple arrangements in various stages of development. In September 1995, the Company entered into a licensing and development agreement, and a supply agreement, with Ethicon, Inc. ("Ethicon"), an affiliate of Johnson & Johnson Company, with respect to the Company's surgical adhesives and sealants program. The Company expended the majority of its resources in furtherance of its program with Ethicon. Pursuant to its rights under the relevant agreements, Ethicon terminated its relationship with the Company as of December 17, 1997, relative to the tissue adhesives and sealants program, thereby terminating the Company's opportunity to receive further milestone payments under the agreements. Although the Company retains the rights to all its technology, the termination of the agreements with Ethicon has materially adversely affected the Company. TECHNOLOGICAL AND COMMERCIAL UNCERTAINTIES The Company's technological strategy of designing and producing unique biocompatible materials based on genetically engineered proteins is commercially unproven. The process of developing products and achieving regulatory approvals is time consuming and prone to delays. Except for limited sales of ProNectin(R) F, the Company has not completed the development of any product or generated any significant revenues from product sales. The Company's success will depend upon its ability to allocate sufficient resources to products with the most commercial potential, and to design and produce biocompatible materials with the intended chemical, biological and functional properties needed for commercial acceptance. -4- The commercial viability of the Company's products will also depend on the success of its research and development activities, its ability to secure strategic alliances appropriate to a product's development, marketing and distribution requirements, and its ability to manufacture its products in sufficient quantity under regulated conditions to meet product demand. The product candidates the Company is currently pursuing will require substantial further development, testing and regulatory approvals; there can be no assurance that these efforts will result in commercially acceptable products. Further, there can be no assurance that such products can be produced in commercial quantities at reasonable costs, can be effectively marketed in a timely fashion, will have significant benefits compared to competitive products on the market at the time of product introduction, or will be accepted for use by the target markets. HISTORY OF OPERATING LOSSES; FUTURE CAPITAL REQUIREMENTS The Company has incurred operating losses since its inception in 1998, and will continue to do so for at least several more years. As of September 30, 1997, the Company had an accumulated deficit of approximately $22,838,000, and has continued to incur losses since that date. Any potential contract revenues derived from collaborative agreements with possible strategic partners will, alone, be insufficient for the Company to become profitable. Substantial additional capital resources will be required to fund increasing expenditures related to the Company's research and development activities, establishment and scale-up of appropriate manufacturing capabilities, preclinical and clinical testing, regulatory compliance, business development activities, patent prosecution and other factors. Further, the timing of these expenses, and possible offsetting contract revenues, is highly uncertain and may produce financial results that fluctuate significantly from period to period. The Company believes that its current capital resources will be sufficient to fund its operating losses until April 1998. The Company is actively pursuing a number of potential approaches to meet the continuing capital requirements of its operations, such as additional collaborative agreements and public or private financings. There can be no assurance that the Company will be able to raise sufficient additional capital funds before the end of this period, if at all, or that such financing will be available on acceptable terms. If adequate funds are not available, the Company will be required to significantly curtail its operations and relinquish rights to major portions of its technology or products. COMPETITION AND TECHNOLOGICAL CHANGE The areas of business in which the Company engages and proposes to engage are characterized by rapidly evolving technology and intense competition. The anticipated commercial uses of the Company's biomaterials are primarily end-use products for medical applications that require other components as part of a system. End-use products using or incorporating the Company's biomaterials would compete with other products that rely on the use of alternative materials or components. Technologies which compete with those of the Company are, therefore, diverse, complex and numerous. Competition in the biomedical and surgical repair markets is particularly significant. The Company's competitors in those markets include major pharmaceutical, surgical product, chemical and specialized biopolymer companies, many of which have financial, technical, research and development and marketing resources significantly greater than those of the Company. Academic institutions and other public and private research organizations are also conducting research and seeking patent protection, and may commercialize products on their own or through joint ventures. Most of the Company's competitors depend on technology other than protein engineering for developing products, for example Focal, Inc. and Closure Medical Corp. The Company believes that research into similar protein engineering technology is currently being conducted by DuPont and several university laboratories. -5- The primary competitive factors in the biomedical and surgical repair products market are performance, cost, safety, reliability, ease of use and commercial production capabilities. The Company believes that its ability to compete in this market will be enhanced by its issued patent claims, the breadth of its other pending patent applications and its experience in protein engineering. However, the Company currently does not have the resources to compete commercially without the use of collaborative agreements with third parties. The Company's product technology competes for corporate development and marketing partnership opportunities with numerous other biotechnology companies, research institutes, academic institutions and established pharmaceutical companies. There can be no assurance that the Company's competitors will not succeed in developing products based on the Company's technology or other technologies that are more effective than any which are being developed by the Company, or which would render the Company's technology and products obsolete and non-competitive. MANUFACTURING UNCERTAINTIES To date, the Company has manufactured limited amounts of its biomedical products for internal testing and, in certain cases, evaluation and testing by corporate partners and other third parties. The development and commercialization of certain biomedical products will require the Company, pursuant to applicable governmental regulations, to upgrade its manufacturing facilities and to obtain manufacturing approvals from the United States Food and Drug Administration (the "FDA"). The Company has recently upgraded its production methods to achieve "Good Laboratory Practice" compliance necessary for producing materials used to generate preclinical data that is reviewed by the FDA. The Company is currently considering alternative methods for increased production of its biomedical and other product candidates for clinical requirements under Good Manufacturing Practice ("GMP") conditions. For example, the Company may upgrade and expand its existing facility; however, there can be no assurance that, if desired, the Company could adequately develop, fund, implement and manage such a manufacturing facility. Alternatively, the Company may establish external contract manufacturing arrangements; however, there can be no assurance that such arrangements, if desired, could be entered into or maintained on acceptable terms, if at all, or would comply with applicable governmental regulations. The Company has not yet developed a process to manufacture its product candidates on a commercial scale. There can be no assurance that a process can be developed by the Company or any other party at a cost or in quantities necessary to become commercially viable. Alternative methods may be needed for producing commercial quantities of products, if any. The actual method, or combination of methods, that the Company may ultimately pursue will depend on a number of factors, including availability, needed quantities, cost and governmental regulations. There is no assurance that the Company will successfully assess the ability of such production methods or establish contract manufacturing arrangements to meet its commercial objectives, or that such methods and arrangements would not adversely affect the Company's margins or its ability to compete in the marketplace. UNCERTAINTY OF REGULATORY COMPLIANCE AND APPROVALS Regulation by governmental authorities in the United States and other countries is a significant factor affecting the success of products resulting from biotechnological research. The Company's current operations and products are, and anticipated products and operations will be, subject to substantial regulation by a variety of local, state, federal and foreign agencies, particularly those products and operations related to biomedical applications. The Company's activities are subject to regulation primarily under the Occupational Safety and Health Act, which requires the Company to provide a "material data safety sheet" to its customers setting forth certain information regarding the Company's products. -6- Pre-clinical and clinical testing and pre-market approval from the FDA is required for new medical devices, drugs or vaccines, a generally costly and time-consuming process. If the Company does not directly produce and sell medical devices, drugs or vaccines, it may not be directly affected by these regulations. However, the Company's anticipated customers and corporate partners would be required to obtain such approvals. Additionally, the Company may be required to file and maintain with the FDA a "Master File" containing information regarding the Company's products. There can be no assurance that the Company's customers and corporate partners will be able to obtain or maintain the necessary approvals from the FDA or that the Company will be able to maintain a Master File in accordance with FDA regulations. In either case, the Company's anticipated business could be adversely affected. Because the Company intends for its biomaterials to be used as medical devices, it may be required to conform its operations to the FDA's GMP regulations. GMP regulatory requirements are rigorous, and there can be no assurance that GMP status could be obtained in a timely manner and without the expenditure of substantial resources, if at all. The Company may also be required to register its facility with the FDA as an establishment involved in the manufacture of medical devices. The Company's research, development and production activities are, or may be, subject to various federal and state laws and regulations relating to environmental quality and the use, discharge, storage, transportation and disposal of toxic and hazardous substances. The Company's future activities are expected to be subject to regulation under the Toxic Substances Control Act, which requires the Company to obtain pre-manufacturing approval for any new "chemical material" the Company produces for commercial use that does not fall within the FDA's regulatory jurisdiction. The Company believes it is currently in compliance with such laws and regulations applicable to its current operations. Although the Company intends to use its best efforts to comply with all laws and regulations in the future, there can be no assurance that the Company will be able to fully comply with such laws, or that full compliance will not require substantial capital expenditures. There can be no assurance that future approvals will be sought or obtained, and the failure to obtain or maintain these approvals, or any substantial delay in obtaining these approvals, would likely have a material adverse effect on the Company's operations. DEPENDENCE ON KEY EMPLOYEES As of Feburary 2, 1998, the Company had thirty-three full-time employees and two part-time employees, of whom seven hold Ph.D. degrees in the chemical or biological sciences. The success of the Company will depend largely upon the efforts of its scientists and certain of its executive officers. The loss of services of any one of these individuals would have a material adverse effect on the Company's business opportunities and prospects. The recruitment and retention of additional qualified management and scientific personnel is also critical to the Company's success. There can be no assurance that the Company will be able to attract and retain required personnel on acceptable terms, due to the competition for such experienced personnel from other biotechnology, pharmaceutical and chemical companies, universities and non-profit research institutions. The Company does not maintain "key-man" or similar life insurance policies with respect to such persons to compensate the Company in the event of their deaths. PRODUCT LIABILITY Product liability claims may be asserted with respect to the Company's technology or products either directly or through the Company's strategic partners. The Company currently has no product liability insurance. Although the Company may seek insurance against the risk of product liability in the future, there can be no assurance that acceptable levels of insurance coverage with appropriate terms will be obtainable, or that the assertion of a product liability claim would not materially adversely affect the business or financial condition of the Company. -7- PATENTS AND TRADE SECRETS The Company's success will depend, in part, on its ability to obtain patent or other protection for its technology and product candidates. The Company seeks to obtain such protection through patents, maintenance of trade secrets and contractual agreements. The success of the Company will also depend in part on the Company not infringing patents issued to competitors or other proprietary rights of third parties. To date, seven United States patents have been issued to the Company, three additional patents have been allowed and eleven additional patent applications are pending. The patent position of biotechnology companies is highly uncertain and involves complex legal, scientific and factual questions. There can be no assurance that patents will issue from any of the Company's pending patent applications or that, if patents do issue, the claims allowed will be sufficiently broad to protect the Company's technology and product candidates. In addition, there can be no assurance that any patents previously or subsequently issued to the Company will not be challenged, invalidated or circumvented, or that the rights granted thereunder will provide any proprietary protection or competitive advantage to the Company. Competitors may have filed patent applications or may have obtained patents and other proprietary rights relating to products or processes similar to and competitive with those of the Company. The scope and validity of such patents, the extent to which the Company may be required to obtain licenses under these patents or other proprietary rights, and the cost and availability of such licenses are presently unknown. No assurance can be made that any licenses required under any patents or proprietary rights will be made available to the Company on acceptable terms, if at all. Further, the Company may enter into collaborative research and development arrangements with strategic partners which may result in the development of new technologies or products. There is no assurance that disputes will not arise in the future with respect to the ownership of rights to any technology or products that may be so developed. The Company also seeks to protect its intellectual property in part by confidentiality agreements with its employees and consultants. There can be no assurance that these agreements will not be breached, that the Company will have an adequate remedy for any breach, or that the Company's trade secrets will not otherwise become known or independently discovered by competitors. DIVIDEND POLICY The Company has never paid dividends on its common stock, and given its continuing loss situation, does not anticipate paying any cash dividends on the common stock in the foreseeable future. Additionally, the holders of the Company's Series D Preferred stock have certain preferences which entitle them to cumulative dividends prior to the payment of any cash dividends on the Company's common stock. VOLATILITY OF TRADING PRICE There has been significant volatility in market prices of securities of biotechnology companies, and the trading price of the Shares could be subject to wide fluctuations. Factors such as announcements of technological innovations and new commercial products by the Company's competitors, adverse results in product testing, litigation, governmental regulation or adverse patent or proprietary rights developments could have a significant adverse impact on the market price of the Company's common stock. -8- INVESTMENT COMPANY ACT CONSIDERATIONS The Company believes that it is primarily engaged in business other than investing, reinvesting, owning, holding or trading in securities. The Company invests its cash in cash equivalents and short-term investments of high quality, following the investment guidelines approved by the Board of Directors. However, there can be no assurance that the Company may not be required to comply with the registration requirements of the Investment Company Act of 1940. Such registration requirements would have a material adverse effect upon the Company. MATERIAL CHANGES In September 1995 the Company entered into a licensing and development agreement, and a supply agreement, with Ethicon with respect to the Company's surgical adhesives and sealants program. If these agreements had not been terminated, Ethicon would have received exclusive worldwide development, marketing and distribution rights to products produced under the Company's proprietary technology rights. In exchange, the Company would have received research and development payments and milestone payments, as well as potential manufacturing and royalty payments. Ethicon maintained the right to terminate the agreements at any time. On December 16, 1997, Ethicon exercised its rights to terminate the agreements, effective December 17, 1997. As a result of the termination, Ethicon has no further financial obligations to the Company. For the agreements to have remained in force, Ethicon would have been required to select one specific protein polymer adhesive formulation for commercial development and regulatory approval, and to commit to accomplishing these goals within specific timelines. By declining to proceed with acceptance of a specific product formulation, Ethicon relinquished all rights to the underlying technology as well as its control over the Company's right to establish other relationships in the field of tissue adhesives and sealants. The termination of the Ethicon agreements has adversely affected the Company. The Company believes that its current capital resources will be sufficient to fund its operating losses until April 1998. There can be no assurance that the Company will be able to raise sufficient additional funds before the end of this period, if at all, or that such financing will be available on acceptable terms. If adequate funds are not available, the Company will be required to significantly curtail its operating plans and relinquish rights to major portions of the Company's technology or products. SELLING SECURITYHOLDERS The Shares offered hereby were issued to the Selling Securityholders pursuant to (i) their exercise of certain warrants in April 1996 for an exercise price of $1.25 per share, (ii) their conversion of certain shares of the Company's Series D Convertible Preferred Stock ("Series D Preferred Stock") in September 1997 at a conversion ratio of 49.2307692 shares of Common Stock for each share of Series D Preferred Stock held, and (iii) the payment of accumulated dividends on the Series D Preferred Stock. Such warrants constituted all of the 432,000 warrants (the "Series C Warrants") which were originally issued and sold by the Company to the Selling Securityholders and other investors along with the Company's previously outstanding Series C Convertible Preferred Stock in 1994, and all of the 500,960 warrants (the "Series D Warrants") which were originally issued and sold by the Company to the Selling Securityholders and other investors along with the Company's Series D Preferred Stock in 1995. Such shares of Series D Preferred Stock so converted constitute 20,973.42 of the 49,186.84 shares of the Company's Series D Preferred Stock which were originally issued and sold by the Company to the Selling Securityholders and other investors in 1995. In connection with the issuance of the Series C Warrants, the Series D Warrants and the Series D Preferred Stock, the Company and the Selling Securityholders entered into a Registration Rights Agreement pursuant to which the Registration Statement, of which this Prospectus is a part, was filed. The Company has agreed to use its best efforts to cause such Registration Statement to become effective under the Securities Act. -9- The following table sets forth as of February 4, 1998, and upon completion of the offering described in this Prospectus, information with regard to the beneficial ownership of the Company's Common Stock by the Selling Securityholders. The Selling Securityholders may not have a present intention of selling the Shares and may offer no Shares for sale or less than the number of the Shares indicated, or may sell the Shares by a means other than this offering.

__________________________________ * Amount represents less than 1% of the Common Stock. As of February 4, 1998, the Company had 10,429,094 shares of Common Stock outstanding. /1/ The persons named in the above table have sole voting and investment power with respect to all shares beneficially owned by them, subject to community property laws where applicable, unless otherwise noted. Information with respect to beneficial ownership is based upon the Company's stock records and data supplied to the Company by the Selling Securityholders. /2/ Beneficial ownership is determined in accordance with rules of the Securities and Exchange Commission, and includes, generally, voting power and/or investment power with respect to securities. Shares of Common Stock subject to options or warrants exercisable within 60 days are deemed outstanding for computing the percentage of the person holding such options or warrants but are not deemed outstanding for computing the percentage of any other person. Except as indicated by footnote, and subject to joint ownership with spouses and community property laws where applicable, the persons named in the table above have sole voting and investment power with respect to all shares of Common Stock shown as beneficially owned by them. /3/ The Selling Securityholders may offer less than the amount of Shares indicated. No representation is made that any Shares will or will not be offered for sale. /4/ This assumes that all Shares owned by the Selling Securityholders which are offered hereby are sold. The Selling Securityholders reserve the right to accept or reject, in whole or in part, any proposed purchase of Shares. /5/ Includes shares of Common Stock issuable upon conversion of 27,317 shares of the Company's Series D Preferred Stock at a conversion price of $3.75 per share. The number of shares of Common Stock receivable upon conversion of each share of Series D Preferred Stock is equal to $100 divided by the lesser of (i) $3.75 or (ii) the market price at the time of conversion. Johnson & Johnson Development Corporation ("JJDC") has shared voting and investment power with respect to all shares of Common Stock with its parent company, Johnson & Johnson. JJDC's affiliate, Ethicon, Inc., was formerly a party to a series of agreements related to the development of tissue adhesives and sealants. See "Material Changes." /6/ Taurus Advisory Group may be deemed to be the beneficial owner of these 2,209,454 shares, which in the aggregate would constitute 21.3% of the shares of common stock outstanding, to the extent that it has discretionary authority to vote or dispose of such shares. Taurus Advisory Group expressly disclaims such beneficial ownership. -10- PLAN OF DISTRIBUTION The Shares offered hereby may be sold from time to time by the Selling Securityholders. Such sales may be made on one or more exchanges or in the over-the-counter market (including NASDAQ) or otherwise, at prices and at terms then prevailing or at prices related to the then current market price, or in negotiated transactions. The Shares may be sold by each of the Selling Securityholders acting as principal for its own account or in ordinary brokerage transactions and transactions in which the broker solicits purchasers. In effecting sales, broker-dealers engaged by the Selling Securityholders may arrange for other broker-dealers to participate in the resales. Broker-dealers or agents may receive compensation in the form of commissions, discounts or concessions from Selling Securityholders in amounts to be negotiated in connection with the sale. Such broker-dealers and any other participating broker-dealers may be deemed to be "underwriters" within the meaning of the Securities Act in connection with such sales, and any such commission, discount or concession may be deemed to be underwriting discounts or commissions under the Securities Act. In addition, any securities covered by this Prospectus which qualify for sale pursuant to Rule 144 may be sold under Rule 144 rather than pursuant to this Prospectus. The Selling Securityholders may agree to indemnify any broker-dealer or agent that participates in transactions involving sales of the Shares against certain liabilities, including liabilities arising under the Securities Act. The Company has agreed to indemnify the Selling Securityholders against certain liabilities in connection with the offering of the Shares, including liabilities arising under the Securities Act. It is not possible at the present time to determine the price to the public in any sale of the Common Stock by the Selling Securityholders. Accordingly, the public offering price and the amount of any applicable underwriting discounts and commissions will be determined at the time of such sale by the Selling Securityholders. The aggregate proceeds to the Selling Securityholders from the sale of the Common Stock will be the purchase price of the Common Stock sold less all applicable commissions and underwriters' discounts, if any. The Company will pay substantially all the expenses incident to the registration, offering and sale of the Common Stock to the public by Selling Securityholders (currently estimated to be $24,219), other than fees, discounts and commissions of underwriters, dealers or agents, if any, and transfer taxes. USE OF PROCEEDS The Company will not receive any proceeds from the sale of the Shares offered by the Selling Securityholders pursuant to this Prospectus. LEGAL MATTERS The validity of the shares of Common Stock offered hereby has been passed upon by Paul, Hastings, Janofsky & Walker LLP, Los Angeles, California. EXPERTS The financial statements of Protein Polymer Technologies, Inc. appearing in Protein Polymer Technologies, Inc.'s Annual Report (Form 10-KSB, as amended on Form 10-KSB/A filed with the Commission on February 5, 1998) for the year ended December 31, 1996, have been audited by Ernst & Young LLP, independent auditors, as set forth in their report thereon (which contains an explanatory paragraph describing conditions that raise substantial doubt about the Company's ability to continue as a going concern as described in Note 1 to the financial statements) included therein and incorporated herein by reference. Such financial statements are incorporated herein by reference in reliance upon such report given upon the authority of such firm as experts in accounting and auditing. -11- INDEMNIFICATION OF DIRECTORS AND OFFICERS The Bylaws of the Company provide generally for indemnification of officers, directors, agents and employees of the Company to the extent authorized by the Delaware General Corporation Law. Pursuant to Section 145 of the Delaware General Corporation Law, a corporation generally has the power to indemnify its present and former directors, officers, employees and agents against expenses incurred by them in connection with any suit to which they are, or are threatened to be made, a party by reason of their serving in such positions so long as they acted in good faith and in a manner they reasonably believed to be in, or not opposed to, the best interests of the corporation, and with respect to any criminal action, they had no reasonable cause to believe their conduct was unlawful. With respect to suits by or in the right of a corporation, however, indemnification is not available if such person is adjudged to be liable for negligence or misconduct in the performance of his duty to the corporation unless the court determines that indemnification is appropriate. In addition, a corporation has the power to purchase and maintain insurance for such persons. The statute also expressly provides that the power to indemnify authorized thereby is not exclusive of any rights granted under any bylaw, agreement, vote of stockholders or disinterested directors, or otherwise. As permitted by Section 102 of the Delaware General Corporation Law, the Company's stockholders have approved and incorporated provisions into the Company's Certificate of Incorporation eliminating a director's personal liability for monetary damages to the Company and its stockholders arising from a breach of a director's fiduciary duty, except for liability under Section 174 of the Delaware General Corporation Law or liability for any breach of the director's duty of loyalty to the Company or its stockholders, for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law or for any transaction in which the director derived an improper personal benefit. The Company has entered into indemnification agreements with each of its directors and executive officers. These agreements provide substantially broader indemnity rights than those provided under the Delaware General Corporation Law and the Company's Bylaws. The indemnification agreements are not intended to deny or otherwise limit third-party or derivative suits against the Company or its directors or officers, but to the extent a director or officer were entitled to indemnity or contribution under the indemnification agreement, the financial burden of a third-party suit would be borne by the Company, and the Company would not benefit from derivative recoveries against the director or officer. Such recoveries would accrue to the benefit of the Company but would be offset by the Company's obligations to the director or officer under the indemnification agreement. The above discussion of the Company's Bylaws, Certificate of Incorporation and indemnification agreements and of Section 145 of the Delaware General Corporation Law is not intended to be exhaustive and is qualified in its entirety by such Bylaws, Certificate of Incorporation, indemnification agreements and statute. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. -12- PART II INFORMATION NOT REQUIRED IN PROSPECTUS Item 14.

Indemnification of Directors and Officers. - -------- The Bylaws of the Company provide generally for indemnification of officers, directors, agents and employees of the Company to the extent authorized by the Delaware General Corporation Law.

II-1 The Company has entered into indemnification agreements with each of its directors and executive officers.

Exhibits. - -------- 5 Opinion of counsel as to legality of securities being registered. 23.1 Consent of Ernst & Young LLP, independent auditors. 23.2 Consent of counsel (included in Exhibit 5). 24.1 Power of Attorney (included herein on the signature page). Item 17. Undertakings. - -------- The undersigned registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) To reflect in the Prospectus any facts or events arising after the effective date of this registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this registration statement; (iii) To include any material information with respect to the plan of distribution not previously disclosed in this registration statement or any material change to such information in this registration statement; Provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the -------- ------- information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in this Registration Statement. (2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered II-2 therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof; and (3) To remove from registration by means of post-effective amendment any of the securities which remain unsold at the termination of the offering. The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act that is incorporated by reference in this Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue. The undersigned Registrant hereby undertakes that: (1) For purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus filed as part of this Registration Statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this Registration Statement as of the time it was declared effective. (2) For the purpose of determining any liability under the Securities Act, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. II-3 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of San Diego, State of California, on February 5, 1998.
