Investors should carefully consider the information set forth under the heading "Risk Factors." Unless otherwise indicated, the information in this Prospectus assumes the Underwriters' over-allotment option will not be exercised and that the Company's reincorporation into the State of Delaware has been approved by the State of California. This Prospectus contains forward-looking statements that involve risks and uncertainties. The Company's actual results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including those set forth under "Risk Factors" and elsewhere in this Prospectus. THE COMPANY VIVUS, Inc. ("VIVUS" or the "Company") is a leader in the development of advanced therapeutic systems for the treatment of erectile dysfunction. Erectile dysfunction, commonly referred to as impotence, is the inability to achieve and maintain an erection of sufficient rigidity for sexual intercourse. The Company's transurethral system for erection is a non-invasive, easy to use system that delivers pharmacologic agents topically to the urethral lining. In March 1996, the Company submitted a New Drug Application ("NDA") to the Food and Drug Administration ("FDA") for its anticipated first product, MUSE(R) (alprostadil). The FDA accepted the Company's filing for priority review. The Company believes that MUSE (alprostadil), if approved, could become first line therapy for erectile dysfunction. If required approvals are received, the Company intends to market and sell its products initially through a direct sales force in the United States and to distribute its products in foreign markets through distribution, co-promotion or license agreements with corporate partners. In February 1996, the Company entered into an agreement with a wholly owned subsidiary of Cardinal Health, Inc. ("Cardinal") that provides that Cardinal will fulfill the Company's orders and warehouse its products. In May 1996, the Company completed a marketing agreement with Astra AB ("Astra") to distribute the Company's products in Europe, South America, Central America, Australia and New Zealand. As consideration for execution of the marketing agreement, Astra will pay the Company $10 million in June 1996. The Company will be paid up to an additional $20 million in the event it achieves certain milestones. Astra has agreed to purchase product from the Company for resale into the above mentioned markets. The Company has sought and will continue to seek pharmacologic agents suitable for transurethral delivery for which significant safety data already exists. The Company believes that such agents may progress more rapidly through clinical development and the regulatory process. In the second half of 1996, the Company expects to begin a Phase III multi-center trial for its second product candidate, a combination of alprostadil and prazosin delivered via the Company's transurethral system for erection. The Company has several other product candidates in preclinical development. Based on a published study of more than 1,200 men in Massachusetts, the Company estimates that over 30% of males in the United States between the ages of 40 and 70 suffer from moderate to complete erectile dysfunction. The Company believes that similar rates of erectile dysfunction prevail outside the United States. A recent estimate from the NIH Consensus Statement on Impotence (1992) suggests that the number of United States men with erectile dysfunction may be 10 to 20 million. The rate of erectile dysfunction increases significantly with age. The primary medical therapies currently used are needle injection of pharmacologic agents into the penis, vacuum constriction devices, penile implants and oral medications. Despite the detrimental effect erectile dysfunction may have on a couple's quality of life, the Company believes that, due in part to the limitations of current therapies, a large number of men suffering from erectile dysfunction currently do not seek medical treatment. The Company believes that its transurethral system for erection, because it is a discreet, easily administered therapy, may increase the number of men who will seek and receive medical treatment for erectile dysfunction. The Company's technology is based on the discovery that the urethra, although an excretory duct, can absorb certain pharmacologic agents into the surrounding erectile tissues. The Company is the exclusive assignee of issued patents and patent applications that were filed by ALZA Corporation ("Alza") based on inventions by the Company's founding scientist while at Alza. The Company is also the exclusive licensee of other United States and foreign patents and patent applications that relate to the transurethral delivery of pharmacologic agents for the treatment of erectile dysfunction. VIVUS was incorporated in California in April 1991 and reincorporated into Delaware on May 24, 1996, pending approval from the State of California. The Company's principal executive offices are located at 545 Middlefield Road, Suite 200, Menlo Park, California 94025. The Company's telephone number is (415) 325-5511. 3 5 THE OFFERING Common Stock Offered by the Company............ 2,000,000 shares Common Stock to be Outstanding after the Offering..................................... 15,804,665 shares(1) Use of Proceeds................................

Prospective investors should carefully consider the following risk factors, in addition to other information contained in this Prospectus, in evaluating an investment in the shares offered hereby. This Prospectus contains forward-looking statements that involve risks and uncertainties. The Company's actual results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including those set forth in the following risk factors and elsewhere in this Prospectus. DEPENDENCE ON THE COMPANY'S TRANSURETHRAL SYSTEM FOR ERECTION The Company currently relies upon a single therapeutic approach to treat erectile dysfunction, its transurethral system for erection. No assurance can be given that the Company's therapeutic approach, or its proposed pharmacologic formulations, will be shown to be safe and effective or ultimately be approved by appropriate regulatory agencies. Certain side effects have been found to occur with the use of MUSE (alprostadil). Mild to moderate transient penile/perineal pain was suffered by 21 percent to 42 percent of patients (depending on dosage) treated with MUSE (alprostadil) in the Company's Phase II/III Dose Ranging study. Moderate to severe decreases in blood pressure were experienced by one percent to four percent of patients (depending on dosage) treated with MUSE (alprostadil) in such study. The existence of side effects or dissatisfaction with product results may impact a patient's decision to use or continue to use, or a physician's decision to recommend, MUSE (alprostadil) as a therapy for the treatment of erectile dysfunction thereby affecting the commercial viability of MUSE (alprostadil). The Company has never commercially introduced a product and no assurance can be given that any of the Company's products, if approved, will be successfully introduced. In addition, technological changes or medical advancements could diminish or eliminate the commercial viability of the Company's products. As a result of the Company's single therapeutic approach and its current focus on MUSE (alprostadil), the failure to obtain an approval of its NDA for MUSE(alprostadil) on a timely basis, if at all, or to successfully commercialize such product would have an adverse effect on the Company and could threaten the Company's ability to continue as a viable entity. GOVERNMENT REGULATION AND UNCERTAINTY OF PRODUCT APPROVALS The Company's research, preclinical development, clinical trials, manufacturing and marketing of its products are subject to extensive regulation by numerous governmental authorities in the United States and other countries. Clinical trials, manufacturing and marketing of the Company's products will be subject to the rigorous testing and approval processes of the FDA and equivalent foreign regulatory agencies. The process of obtaining FDA and other required regulatory approvals is lengthy and expensive. The time required for FDA approvals is uncertain and typically takes a number of years, depending on the type, complexity and novelty of the product. Since the Company's products involve transurethral delivery, a new therapeutic approach, regulatory approvals may be obtained more slowly than for products produced using more conventional delivery systems. The Company completed pivotal clinical trials in 1995 and submitted an NDA for its anticipated first product, MUSE (alprostadil), to the FDA in March 1996. While the Company believes its NDA filing was substantially complete, there can be no assurance that the Company will not be required to conduct additional research or clinical trials. Although the Company's NDA was accepted for priority review by the FDA, there can be no assurance that FDA approval will be granted on a timely basis, if at all, or if granted, that such approval will not contain significant limitations in the form of warnings, precautions or contraindications with respect to condition of use. Any delay in obtaining, or failure to obtain, such approval would adversely affect the Company's ability to generate product revenue. The Company's clinical trials for future products will seek safety data as well as efficacy data and will require substantial time and significant funding. There is no assurance that clinical trials will be completed successfully within any specified time period, if at all. Furthermore, the FDA may suspend clinical trials at any time if it is believed that the subjects participating in such trials are being exposed to unacceptable health risks. There can be no assurance that FDA or other regulatory approvals for other products developed by the 5 7 Company will be granted on a timely basis, if at all, or if granted, that such approval will not contain significant limitations in the form of warnings, precautions or contraindications with respect to conditions of use. Any delay in obtaining, or failure to obtain, such approvals could adversely affect the Company's ability to generate product revenue. Failure to comply with the applicable regulatory requirements can, among other things, result in fines, suspensions of regulatory approvals, product recalls, operating restrictions and criminal prosecution. In addition, the marketing and manufacturing of pharmaceutical products are subject to continuing FDA review, and later discovery of previously unknown problems with a product, manufacturer or facility may result in the FDA requiring further clinical research or restrictions on the product or the manufacturer, including withdrawal of the product from the market. The restriction, suspension or revocation of regulatory approvals or any other failure to comply with regulatory requirements would have a material adverse effect on the Company's business, financial condition and results of operations. See "Business -- Government Regulation." The Company obtains the necessary raw materials and components for the manufacture of MUSE (alprostadil) from third parties. The Company currently contracts with contract manufacturing organizations that are required to comply with strict standards established by the Company. Contract manufacturers are required by the Federal Food, Drug, and Cosmetic Act, as amended, and by FDA regulations to follow Good Manufacturing Practice ("GMP"). The Company is required to identify its suppliers to the FDA and is dependent upon its contract manufacturers and its suppliers to comply with the Company's specifications and, as required, GMP or similar standards imposed by foreign regulators. There can be no assurance that the FDA, or a state, local or foreign regulator will not take action against a contract manufacturer or supplier found to be violating applicable regulations. Such an action could have a material adverse effect on the Company's business, financial condition and results of operations. See "Business -- Raw Materials and Manufacturing." LIMITED MANUFACTURING EXPERIENCE AND DEPENDENCE ON SOLE CONTRACT MANUFACTURER The Company has only limited experience in manufacturing MUSE (alprostadil) and has not yet manufactured it in commercial quantities. As a result, the Company has no experience manufacturing its product in volumes necessary for the Company to achieve significant commercial sales, and there can be no assurance that reliable high volume manufacturing can be achieved at commercially reasonable cost. If the Company encounters any manufacturing difficulties, including problems involving production yields, quality control and assurance, supplies of components or raw materials or shortages of qualified personnel, it could have a material adverse effect on the Company's business, financial condition and results of operations. The formulation, filling, packaging and testing of MUSE (alprostadil) is performed by Paco Pharmaceutical Services, Inc. ("Paco"), a wholly owned subsidiary of The West Company, at its facility in Lakewood, New Jersey. In June 1995, the Company completed construction of its approximately 6,000 square feet of dedicated manufacturing and testing space within Paco's facility. The Company will be required to expand its manufacturing and testing space at Paco or to find additional facilities, if regulatory approval is obtained and MUSE (alprostadil) is successfully introduced. The Company also intends to establish a Company owned and operated manufacturing facility in Europe. Until the Company develops an in-house manufacturing capability or is able to identify and qualify alternative contract manufacturers, it will be entirely dependent upon Paco for the manufacture of its products. As part of the approval process for the Company's NDA, Paco will be subject to an audit by the FDA as part of its GMP inspection. There can be no assurance that the facility will receive the necessary GMP approval. There can be no assurance that the Company's reliance on Paco or others for the manufacture of its products will not result in problems with product supply, and there can be no assurance that the Company will be able to establish a second manufacturing facility or expand its existing facility at Paco. Interruptions in the availability of products could delay or prevent the development and commercial marketing of MUSE (alprostadil) and other potential products and would have a material adverse effect on the Company's business, financial condition and results of operations. See "Business -- Raw Materials and Manufacturing" and "-- Government Regulation." 6 8 LIMITED SALES AND MARKETING EXPERIENCE AND DEPENDENCE ON THIRD PARTIES The Company has no experience in the sale, marketing and distribution of pharmaceutical products. If required approvals are received, the Company intends to market and sell its products initially through a direct sales force in the United States. In order to market its products directly, the Company must develop a sales force with the proper technical expertise. There can be no assurance that the Company will be able to build a sales force, or that the Company's sales and marketing efforts will be successful. In February 1996, the Company entered into an agreement with Cardinal. Under this agreement, Cardinal will warehouse the Company's finished goods, take customer orders, pack and ship its product, invoice customers and collect related receivables. The Company will also have access to Cardinal's information systems that support these functions. As a result of this agreement with Cardinal, the Company is dependent on Cardinal's efforts to fulfill orders and warehouse its products effectively. There can be no assurance that such efforts will be successful. In May 1996, the Company completed a marketing agreement with Astra AB ("Astra") to distribute the Company's products in Europe, South America, Central America, Australia and New Zealand. As consideration for execution of the marketing agreement, Astra will pay the Company $10 million in June. The Company will be paid up to an additional $20 million in the event it achieves certain milestones. The marketing agreement does not have minimum purchase commitments, and Astra may take up to twelve months to introduce a product in a given country following regulatory approval in such country. As a result of this marketing agreement with Astra, the Company is dependent on Astra's efforts to market, distribute and sell the Company's products effectively in the above mentioned markets. There can be no assurance that such efforts will be successful. The Company intends to market and sell its products in other foreign markets through distribution, co-promotion or license agreements with corporate partners. To the extent that the Company enters into distribution, co-promotion or license agreements for the sale of its products, the Company will be dependent upon the efforts of third parties. These third parties may have other commitments, and there can be no assurance that they will commit the necessary resources to effectively market, distribute and sell the Company's product. See "Business -- Sales and Marketing." INTENSE COMPETITION Competition in the pharmaceutical and medical products industries is intense and is characterized by extensive research efforts and rapid technological progress. Certain treatments for erectile dysfunction exist, such as needle injection therapy, vacuum constriction devices, penile implants and oral medications, and the manufacturers of these products will continue to improve these therapies. In July 1995, the FDA approved the use of alprostadil in The Upjohn Company's ("Upjohn") needle injection therapy product for erectile dysfunction. Previously, Upjohn had obtained approval in a number of European countries. Additional competitive therapies under development include an oral medication, Viagra, by Pfizer, Inc. which is currently in Phase III clinical trials. Other large pharmaceutical companies are also actively engaged in the development of therapies for the treatment of erectile dysfunction. These companies have substantially greater research and development capabilities as well as substantially greater marketing, financial and human resources than the Company. In addition, these companies have significantly greater experience than the Company in undertaking preclinical testing, human clinical trials and other regulatory approval procedures. There are also small companies, academic institutions, governmental agencies and other research organizations that are conducting research in the area of erectile dysfunction. For instance, Zonagen, Inc. and Pentech Pharmaceutical, Inc. have oral medications under development. These entities may also market commercial products either on their own or through collaborative efforts. The Company's competitors may develop technologies and products that are available for sale prior to the Company's products or that are more effective than those being developed by the Company. Such developments would render the Company's products less competitive or possibly obsolete. If the Company is permitted to commence commercial sales of products, it will also be competing with respect to marketing capabilities and manufacturing efficiency, areas in which it has limited experience. See "Business -- Competition." 7 9 PROPRIETARY RIGHTS AND RISK OF LITIGATION The Company's success will depend, in large part, on the strength of its current and future patent position relating to the transurethral delivery of pharmacologic agents for the treatment of erectile dysfunction. The Company's patent position, like other pharmaceutical companies, is highly uncertain and involves complex legal and factual questions. Claims made under patent applications may be denied or significantly narrowed and issued patents may not provide significant commercial protection to the Company. The Company could incur substantial costs in proceedings before the United States Patent Office, including interference proceedings. These proceedings could also result in adverse decisions as to the priority of the Company's licensed or assigned inventions. There is no assurance that the Company's patents will not be challenged or designed around by others. The Company is aware of a patent application involving the transurethral application of prostaglandin E2 in the United States. The corresponding application in Europe has been abandoned. Failure of the Company's licensed patents to block issuance of such patent could have a material adverse effect on the Company's business, financial condition and results of operations. There can be no assurance that the Company's products do not or will not infringe on the patent or proprietary rights of others. A patent opposition to the Company's exclusively licensed European patents has been filed with the European Patent Office. The Company is vigorously defending the patents, however an adverse decision could affect the Company's ability, based on its patent rights, to limit potential competition in Europe. The Company may be required to obtain additional licenses to the patents, patent applications or other proprietary rights of others. There can be no assurance that any such licenses would be made available on terms acceptable to the Company, if at all. If the Company does not obtain such licenses, it could encounter delays in product introductions while it attempts to design around such patents, or the development, manufacture or sale of products requiring such licenses could be precluded. The Company believes there will continue to be significant litigation in the pharmaceutical industry regarding patent and other intellectual property rights. A former consultant to the Company has claimed that he is the inventor of certain technology disclosed in one of the Company's patents. The former consultant further claims that the Company defrauded him by allegedly failing to inform him that it intended to use and patent this technology and by failing to compensate him for the technology in the manner allegedly promised. The Company has filed a declaratory relief action against the former consultant in the United States District Court for the Northern District of California that seeks to determine the Company's rights with respect to the allegations. The former consultant has not yet been served in the proceeding. In a separate matter, the licensors in an agreement by which the Company acquired a patent license have recently filed a lawsuit alleging that they were defrauded in connection with the renegotiation of the license agreement between the Company and the licensors. In addition to monetary damages, the licensors seek to return to the terms of the original license agreement. The Company has conducted a review of the circumstances surrounding these two matters and believes that the allegations are without merit. Although the Company believes that it should prevail, the uncertainties inherent in litigation prevent the Company from giving any assurances about the outcome of such litigation. See "Business -- Litigation." The Company also relies on trade secrets and other unpatented proprietary technology. No assurance can be given that the Company can meaningfully protect its rights in such unpatented proprietary technology or that others will not independently develop substantially equivalent proprietary products and processes or otherwise gain access to the Company's proprietary technology. The Company seeks to protect its trade secrets and proprietary know-how, in part, with confidentiality agreements with employees and consultants. There can be no assurance that these agreements will not be breached, that the Company will have adequate remedies for any breach or that the Company's trade secrets will not otherwise become known or be independently developed by competitors. In addition, protracted and costly litigation may be necessary to enforce and determine the scope and validity of the Company's proprietary rights. See "Business -- Licensed Patents and Proprietary Rights." 8 10 DEPENDENCE ON DUAL SOURCE OF SUPPLY To date, the Company has obtained its supply of alprostadil from two sources. The first is Spolana Chemical Works AS in Neratovice, Czech Republic ("Spolana") pursuant to a supply agreement that expires at the end of 1996. In January 1996, the Company completed a long-term alprostadil supply agreement with CHINOIN Pharmaceutical and Chemical Works Co., Ltd. ("Chinoin"). Chinoin is the Hungarian subsidiary of the French pharmaceutical company Sanofi Winthrop. The Company's sources of supply will be subject to GMP requirements of the FDA. There can be no assurance FDA approval will be received. Alprostadil, a generic drug, is extremely difficult to manufacture and is only available to the Company from a limited number of other suppliers, none of which currently produce it in commercial quantities. While the Company is seeking additional sources, there can be no assurance that it will be able to identify and qualify such sources. The Company is required to identify its suppliers to the FDA, and the FDA may require additional clinical trials or other studies prior to accepting a new supplier. Unless the Company secures and qualifies additional sources of alprostadil, it will be entirely dependent upon Spolana and Chinoin for the delivery of alprostadil. If interruptions in the supply of alprostadil were to occur for any reason, including a decision by Spolana and/or Chinoin to discontinue manufacturing, political unrest, labor disputes or a failure of Spolana and/or Chinoin to follow regulatory guidelines, the development and commercial marketing of MUSE (alprostadil) and other potential products could be delayed or prevented. An interruption in the Company's supply of alprostadil would have a material adverse effect on the Company's business, financial condition and results of operations. See "Business -- Raw Materials and Manufacturing." HISTORY OF LOSSES AND LIMITED OPERATING HISTORY The Company is a development stage company with a limited operating history. The Company has not generated any revenue since its inception in April 1991. At March 31, 1996, the Company had an accumulated deficit of approximately $55.9 million. The Company's losses will increase significantly during the next twelve months as it incurs expenses related to its marketing and sales organization, constructing a second manufacturing plant and expanding the Company's existing plant, preclinical and clinical assessment of potential new products and ongoing research and development activities. To achieve profitability, the Company must successfully obtain required regulatory approvals, manufacture, introduce and market MUSE (alprostadil). The time required to reach profitability is highly uncertain, and there is no assurance that the Company will be able to achieve profitability on a sustained basis, if at all. See "Management's Discussion and Analysis of Financial Condition and Results of Operations." FUTURE CAPITAL NEEDS AND UNCERTAINTY OF ADDITIONAL FINANCING The Company expects to incur substantial additional costs, including expenses related to its marketing and sales organization, a second manufacturing plant and expansion of the Company's existing plant, new product preclinical and clinical costs, ongoing research and development activities and general corporate purposes. The Company anticipates that its existing capital resources and the proceeds from this offering will be sufficient to support the Company's operations through commercial introduction of MUSE (alprostadil) in the United States and Europe but may not be sufficient for the introduction of any additional future products. The Company may have to conduct additional studies or clinical trials in order to obtain regulatory approval of MUSE (alprostadil). Accordingly, the Company anticipates that it may be required to issue additional equity or debt securities and may use other financing sources including, but not limited to, corporate alliances and lease financings to fund the future development and possible commercial launch of its products. The sale of additional equity securities can be expected to result in additional dilution to the Company's stockholders. There can be no assurance that such funds will be available on terms satisfactory to the Company, or at all. Failure to obtain adequate funding could cause a delay or cessation of the Company's product development and marketing efforts and would have a material adverse effect upon the Company's business, financial condition and results of operations. The Company's working capital and additional funding requirements will depend upon numerous factors, including: (i) the ability to obtain and timing and costs of obtaining regulatory approvals; (ii) the level of resources that the Company devotes to sales and marketing capabilities; (iii) the level of resources that the Company devotes to expanding manufacturing capacity; (iv) the activities of 9 11 competitors; (v) the progress of the Company's research and development programs; (vi) the timing and results of preclinical testing and clinical trials; and (vii) technological advances. See "Management's Discussion and Analysis of Financial Condition and Results of Operations -- Liquidity and Capital Resources." DEPENDENCE ON KEY PERSONNEL The Company's progress to date has been highly dependent upon the skills of a limited number of key management personnel. To reach its future business objectives, the Company will need to hire numerous other qualified personnel in the areas of sales, manufacturing, clinical trial management and preclinical testing. There can be no assurance that the Company will be able to hire such personnel, as the Company must compete with other companies, academic institutions, government entities and other agencies. The loss of any of the Company's key personnel or the failure to attract or retain necessary new employees could have an adverse effect on the Company's research, product development and business operations. See "Management" and "Business -- Employees." RISKS RELATING TO INTERNATIONAL OPERATIONS In the event the Company receives necessary foreign regulatory approvals, the Company plans to market its products internationally. Changes in overseas economic conditions, currency exchange rates, foreign tax laws or tariffs or other trade regulations could have a material adverse effect on the Company's business, financial condition and results of operations. The anticipated international nature of the Company's business is also expected to subject it and its representatives, agents and distributors to laws and regulations of the foreign jurisdictions in which they operate or the Company's products are sold. The regulation of drug therapies in a number of such jurisdictions, particularly in the European Union, continues to develop, and there can be no assurance that new laws or regulations will not have a material adverse effect on the Company's business, financial condition and results of operations. In addition, the laws of certain foreign countries do not protect the Company's intellectual property rights to the same extent as do the laws of the United States. PRODUCT LIABILITY AND AVAILABILITY OF INSURANCE The use of the Company's products in clinical trials may expose the Company to product liability claims and possible adverse publicity. These risks also exist with respect to the Company's products, if any, that receive regulatory approval for commercial sale. The Company currently maintains insurance coverage for the clinical use of its products but does not have insurance coverage for the commercial sale of its products. There can be no assurance that the Company will be able to obtain product liability insurance. There can be no assurance that the Company's present or future insurance will provide adequate coverage or be available at a reasonable cost or that product liability claims would not adversely affect the business or financial condition of the Company. UNCERTAINTY OF PHARMACEUTICAL PRICING AND REIMBURSEMENT In the United States and elsewhere, sales of pharmaceutical products currently are dependent, in part, on the availability of reimbursement to the consumer from third party payors, such as government and private insurance plans. Third party payors are increasingly challenging the prices charged for medical products and services. If the Company succeeds in bringing one or more products to the market, there can be no assurance that these products will be considered cost effective and that reimbursement to the consumer will be available or sufficient to allow the Company to sell its products on a competitive basis. UNCERTAINTY AND POSSIBLE NEGATIVE EFFECTS OF HEALTHCARE REFORM The healthcare industry is undergoing fundamental changes that are the result of political, economic and regulatory influences. The levels of revenue and profitability of pharmaceutical companies may be affected by the continuing efforts of governmental and third party payors to contain or reduce healthcare costs through various means. Reforms that have been and may be considered include mandated basic healthcare benefits, controls on healthcare spending through limitations on the increase in private health insurance premiums and 10 12 Medicare and Medicaid spending, the creation of large insurance purchasing groups and fundamental changes to the healthcare delivery system. Due to uncertainties regarding the outcome of healthcare reform initiatives and their enactment and implementation, the Company cannot predict which, if any, of the reform proposals will be adopted or the effect such adoption may have on the Company. There can be no assurance that future healthcare legislation or other changes in the administration or interpretation of government healthcare or third-party reimbursement programs will not have a material adverse effect on the Company. Healthcare reform is also under consideration in other countries. CONTROL BY EXISTING STOCKHOLDERS Upon completion of this offering, the Company's officers, directors and principal stockholders, and certain of their affiliates, will beneficially own 22.5 percent of the Company's outstanding Common Stock (approximately 22.1 percent assuming the Underwriter's over-allotment option is exercised in full). Such concentration of ownership may have the effect of delaying, defining or preventing a change in control of the Company. Additionally, these stockholders will have significant influence over the election of directors of the Company. This concentration of ownership may allow significant influence and control over Board decisions and corporate actions. POTENTIAL VOLATILITY OF STOCK PRICE The stock market has recently experienced significant price and volume fluctuations unrelated to the operating performance of particular companies. In addition, the market price of the Company's Common Stock, like the securities of other therapeutic companies without approved products, is likely to be highly volatile and is likely to continue to be so. Factors such as variations in the Company's financial results, comments by security analysts, the Company's ability to scale up its manufacturing capability to commercial levels, the Company's ability to successfully sell its product in the United States and Europe, any loss of key management, the results of the Company's clinical trials or those of its competition, adverse regulatory actions or decisions, evidence regarding the safety or efficacy of the Company's products or those of its competition, announcements of technological innovations or new products by the Company or its competition, changing governmental regulations and developments with respect to FDA submissions, developments with respect to patents or other proprietary rights, product or patent litigation or public concern as to the safety of products developed by the Company, may have a significant effect on the market price of the Company's Common Stock. ANTI-TAKEOVER EFFECT OF SHAREHOLDER RIGHTS PLAN AND CERTAIN CHARTER AND BYLAW PROVISIONS In February 1996, the Company's Board of Directors authorized its reincorporation into the State of Delaware (the "Reincorporation") and adopted a Shareholder Rights Plan. The Shareholder Rights Plan provides for a dividend distribution of one Preferred Share Purchase Right (a "Right") on each outstanding share of the Common Stock. Each Right entitles stockholders to buy 1/100th of a share of VIVUS Series A Participating Preferred Stock at an exercise price of $100.00. The Rights will become exercisable following the tenth day after a person or group announces acquisition of 20 percent or more of the Common Stock, or announces commencement of a tender offer, the consummation of which would result in ownership by the person or group of 20 percent or more of the Common Stock. The Company will be entitled to redeem the Rights at $0.01 per Right at any time on or before the tenth day following acquisition by a person or group of 20 percent or more of the Company's Common Stock. The Company's reincorporation into the State of Delaware was approved by its shareholders and effective in May 1996, pending approval by the State of California. The Shareholder Rights Plan and certain provisions of the Company's Certificate of Incorporation and Bylaws, as adopted in connection with the reincorporation, may have the effect of making it more difficult for a third party to acquire, or of discouraging a third party from attempting to acquire control of the Company. The Company's Certificate of Incorporation allows the Company to issue Preferred Stock without any vote or further action by the stockholders, and certain provisions of the Company's Certificate of Incorporation and Bylaws eliminate the right of stockholders to act by written consent without a meeting, specify procedures for 11 13 director nominations by stockholders and submission of other proposals for consideration at stockholder meetings, and eliminate cumulative voting in the election of directors. Certain provisions of Delaware law could also delay or make more difficult a merger, tender offer or proxy contest involving the Company, including Section 203, which prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years unless certain conditions are met. The Shareholder Rights Plan, the possible issuance of Preferred Stock, the procedures required for director nominations and stockholder proposals and Delaware law could have the effect of delaying, deferring or preventing a change in control of the Company, including without limitation, discouraging a proxy contest or making more difficult the acquisition of a substantial block of the Company's Common Stock. These provisions could also limit the price that investors might be willing to pay in the future for shares of the Company's Common Stock. SHARES ELIGIBLE FOR FUTURE SALE Sales of a substantial number of shares of Common Stock in the public market following this offering could have an adverse effect on the price of the Company's Common Stock. Each of the Company's directors and executive officers has agreed that for a period of 90 days following the date of this Prospectus, such stockholder will not, without the prior written consent of PaineWebber Incorporated, directly or indirectly, offer to sell, sell or otherwise dispose of shares of Common Stock or any securities convertible or exchangeable for shares of Common Stock. Upon the expiration of these lock-up agreements, approximated 2.8 million shares (including shares issuable upon the exercise of outstanding vested options) will become eligible for sale. DILUTION AND ABSENCE OF DIVIDENDS The public offering price is substantially higher than the book value per share of the Common Stock. Assuming a public offering price of $30.25, investors purchasing shares of Common Stock in this offering, based upon the net tangible book value as adjusted per share of Common Stock as of March 31, 1996, will incur immediate and substantial dilution in the amount of $24.38 per share. Future equity financings may cause further dilution to investors. The Company has never paid dividends on its Common Stock and will not pay dividends in the foreseeable future. See "Dilution" and "Dividend Policy." 12 14 USE OF PROCEEDS The net proceeds to the Company from the sale of the 2,000,000 shares of Common Stock offered by the Company hereby are estimated to be $56,370,000 ($64,900,500 if the Underwriters' over-allotment option is exercised in full), assuming a public offering price of $30.25 per share and after deduction of the underwriting discount and estimated offering expenses. The Company anticipates using the net proceeds of this offering for expenses related to its marketing and sales organization, a second manufacturing plant and expansion of the Company's existing plant, new product preclinical and clinical costs, ongoing research and development activities, and general corporate purposes. The exact timing and amount of funds required for specific uses by the Company cannot be precisely determined by the Company at this time. Pending such uses, the Company intends to invest the estimated net proceeds primarily in investment-grade, interest-bearing obligations. The Company believes that its existing cash, cash equivalents and investments combined with the net proceeds from this offering will be sufficient to support the Company's operations through commercial introduction of MUSE (alprostadil) in the United States and Europe but may not be sufficient for the introduction of any additional future products. See "Management's Discussion and Analysis of Financial Condition and Results of Operations -- Liquidity and Capital Resources." PRICE RANGE OF COMMON STOCK The Company's Common Stock is traded on the Nasdaq National Market under the symbol "VVUS." The Company commenced its initial public offering of Common Stock on April 7, 1994 at an initial public offering price of $14.00. The following table sets forth for the periods indicated during 1995 and 1996 the high and low sale prices of the Common Stock as reported by the Nasdaq National Market.

As of May 17, 1995 there were 428 stockholders of record of the Company's Common Stock. DIVIDEND POLICY The Company has never declared or paid cash dividends on its Common Stock. The Company intends to retain earnings and will not pay cash dividends in the foreseeable future. Any future determination to pay cash dividends will be at the discretion of the Board of Directors and will be dependent upon the Company's financial condition, results of operations, capital requirements, general business conditions and such other factors as the Board of Directors deems relevant. 13 15 CAPITALIZATION The following table sets forth the capitalization of the Company as of March 31, 1996, and as adjusted to reflect the sale of the 2,000,000 shares of Common Stock offered by the Company hereby at an assumed public offering price of $30.25 and the receipt of the estimated net proceeds therefrom:

- --------------- (1) Excludes, as of May 31, 1996, 1,647,563 shares of Common Stock issuable upon the exercise of outstanding options granted pursuant to the Company's 1991 Incentive Stock Plan at a weighted average exercise price of $12.70 per share and 264,300 shares of Common Stock issuable upon the exercise of outstanding warrants at an exercise price of $8.63 per share. (2) Vivus was incorporated in California in April 1991 and reincorporated into Delaware on May 24, 1996, pending approval by the State of California. The capitalization table considers the effect of the reincorporation. DILUTION The net tangible book value of the Company as of March 31, 1996 was approximately $35.2 million, or $2.59 per share of Common Stock. The net tangible book value per share is equal to the Company's total tangible assets less total liabilities, divided by the number of shares of Common Stock outstanding. After giving effect to the sale of the 2,000,000 shares of Common Stock offered by the Company hereby at an assumed public offering price of $30.25 per share and the receipt of the estimated net proceeds therefrom, the net tangible book value as adjusted of the Company at March 31, 1996 would have been approximately $91.5 million or $5.87 per share. This represents an immediate increase in net tangible book value of $3.28 per share to existing stockholders and an immediate dilution of $24.38 per share to new investors purchasing shares in this offering. The following table illustrates the per share dilution: Assumed public offering price................................. $30.25 Net tangible book value before offering..................... $2.59 Increase attributable to new investors...................... 3.28 ----- Net tangible book value after offering........................

- --------------- (1) April 16, 1991 (inception) through December 31, 1991. 15 17 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS The following Management's Discussion and Analysis of Financial Condition and Results of Operations contains forward-looking statements that involve risks and uncertainties. The Company's actual results could differ materially from those anticipated in the forward-looking statements as a result of certain factors including those set forth under "Risk Factors" and elsewhere in this Prospectus. OVERVIEW Since its inception in April 1991, VIVUS, Inc. (the Company), a development stage company, has focused on the design and development of products for the treatment of erectile dysfunction. The Company has devoted substantially all its efforts to research and development conducted on its behalf and through collaboration with clinical institutions. The Company's primary product, MUSE (alprostadil), has moved from preclinical development to regulatory application phase over the last three years. The Company has generated a cumulative net loss of $55.9 million for the period from its inception through March 31, 1996. The ability of the Company to successfully obtain regulatory approval for, manufacture, and market MUSE (alprostadil) is dependent on many factors. The Company is subject to a number of risks including the approval of its product, its ability to scale-up its manufacturing capabilities and secure adequate supplies of raw materials, its ability to successfully market, distribute and sell its product and intense competition. Accordingly, there can be no assurance of the Company's future success. Spending increased from 1993 through the period ended March 31, 1996 largely as a result of expanded operational activities related to the Company's Phase II and III clinical trials, preparing the MUSE (alprostadil) NDA for the FDA and expansion of its manufacturing capabilities. Spending levels will continue to increase during 1996 as the Company further develops its commercial manufacturing, marketing and sales capabilities. To date, the Company has received no revenue from product sales or from collaborative agreements. The Company does not anticipate significant revenue from operations for at least two years. The Company does not have any experience in manufacturing or selling MUSE (alprostadil) in commercial quantities. Whether the Company can successfully manage the transition to a large scale commercial enterprise will depend upon the successful further development of its manufacturing capability and its distribution network and attainment of domestic and foreign regulatory approvals for MUSE (alprostadil) and other potential products. Failure to make such a transition successfully would have a material adverse effect on the Company's business, financial condition and results of operations. The Company anticipates that its losses will continue to increase significantly over at least the next twelve months as it expands its operations, prepares for the anticipated commercial introduction of MUSE (alprostadil) and expands its research and development activities with regard to other products. To achieve profitability, the Company must obtain the required regulatory approvals and successfully manufacture, introduce and market MUSE (alprostadil). The time required to reach profitability is highly uncertain, and there can be no assurance that the Company will be able to obtain profitability on a sustained basis, if at all. The Company currently relies on a single therapeutic approach to treat erectile dysfunction, the transurethral system for erection. The Company recently completed Phase III clinical trials and submitted an NDA to the FDA for its anticipated first product, MUSE (alprostadil). While the Company's NDA was accepted for priority review by the FDA, there can be no assurance that FDA approval will be granted on a timely basis, if at all, or if granted, that such approval will not contain significant limitations in the form of warnings, precautions or contraindications with respect to condition of use. Failure to obtain approval of the Company's NDA for MUSE (alprostadil) on a timely basis, if at all, or if granted, the failure to successfully commercialize MUSE (alprostadil) would have a material adverse effect on the Company. In April 1994, the Company successfully completed an initial public offering of 2,473,000 shares of common stock, with net proceeds to the Company of $31,578,000. The Company completed a secondary public offering of 1,800,000 shares of common stock in April 1995. Of the total number of shares offered, 16 18 1,670,000 shares were sold by the Company and 130,000 shares were sold by a stockholder. Net proceeds to the Company were $22,483,000. The Company has an agreement with Alza, executed on December 31, 1993, that provides for the assignment by Alza of patents and patent applications related to the Company's technology. In consideration for the rights granted to the Company under the agreement, the Company issued shares of Common Stock to Alza and is required to pay certain royalties on the sale of any products for the transurethral treatment for erectile dysfunction. To maintain exclusive rights beyond December 31, 1998, the Company issued an additional 200,000 shares of Common Stock to Alza in May 1996 and recorded a charge of $5.9 million to the consolidated statement of operations. RESULTS OF OPERATIONS Three Months Ended March 31, 1996 and 1995 No revenues have been recorded from inception to March 31, 1996. For the three months ended March 31, 1996, research and development expenses were $5,359,000 compared with $5,113,000 for the three months March 31, 1995, an increase of 5%. This increase was due primarily to increased pre-launch manufacturing and quality assurance expenses, which were partially offset by lower clinical costs resulting from the completion of the Phase II and III clinical trials in 1995. General and administrative expenses for the three months ended March 31, 1996 were $1,379,000 compared with $897,000 for the three months ended March 31, 1995, an increase of 54%. This increase resulted primarily from hiring additional personnel to support the growth of the Company's operations, in addition to higher marketing, legal and accounting expenses. Interest income for the three months ended March 31, 1996 was $503,000 compared with $553,000 for the three months ended March 31, 1995. This decrease was primarily the result of lower average invested cash balances. Years Ended December 31, 1995 and 1994 Research and development expenses in 1995 were $21,313,000 compared with $13,916,000 in 1994, an increase of 53%. This increase resulted primarily from the increased expenses supporting the Company's Phase III confirmatory clinical studies and ongoing clinical study programs for MUSE (alprostadil), costs associated with the preparation of the NDA for MUSE (alprostadil), expansion of the Company's manufacturing capability and growth in personnel to support the Company's expanding operations. Clinical trial costs consisted largely of payments to clinical investigators. The Company pays its clinical investigators on a per patient basis. In clinical trials through December 31, 1995, the Company's transurethral system for erection had been used by more than 1,950 men at over 80 sites in the United States and Europe. General and administrative expenses in 1995 were $4,389,000 compared with $2,587,000 in 1994, an increase of 70%. This increase resulted primarily from hiring additional personnel to support the growth of the Company's operations, in addition to higher market research, legal and accounting expenses, and expenses associated with being a public company. Interest income in 1995 was $2,891,000 compared with $1,639,000 in 1994. The increase resulted from higher average invested cash balances as well as higher returns on its cash investments in 1995 due to the favorable effects of higher average interest rates. Years Ended December 31, 1994 and 1993 Research and development expenses in 1994 were $13,916,000 compared with $6,814,000 in 1993, an increase of 104%. This increase resulted primarily from increased purchases of alprostadil, enrollment of additional patients in clinical trials, and contract manufacturing and quality control services. Research and development expenses in 1993 included license fees of $1,380,000. There were no license fees included in research and development expenses in 1994. 17 19 General and administrative expenses in 1994 were $2,587,000 compared with $1,499,000 in 1993, an increase of 73%. This increase resulted primarily from hiring additional personnel to support the growth of the Company's operations, in addition to higher legal and accounting expenses, and expenses associated with being a public company. Interest income in 1994 was $1,639,000 compared with $538,000 in 1993. The increase resulted from higher average invested cash balances associated with the $31,578,000 in net proceeds received from the initial offering in April 1994, in addition to higher average interest rates in 1994. LIQUIDITY AND CAPITAL RESOURCES Since inception, the Company has financed operations primarily from the sale of preferred and common stock. Through March 31, 1996, VIVUS has raised $88,958,000. Cash, cash equivalents and securities available-for-sale totaled $33,772,000 at March 31, 1996 compared with $39,524,000 at December 31, 1995. The Company maintains its current excess cash balances in a variety of interest bearing investment-grade financial investments such as U.S. government securities, corporate debt and certificates of deposit. Principal preservation, liquidity and safety are the primary investment objectives. Cash used in operations in the three months ended March 31, 1996 was $5,403,000 compared with $4,199,000 in the three months ended March 31, 1995. The increased use of cash was primarily due to a net loss of $6,235,000 in the three months ended March 31, 1996 compared with a net loss of $5,457,000 for the same period in 1995. Cash used for operations is expected to increase in 1996 as the Company further develops its commercial manufacturing, marketing and sales capabilities. Prepaid and other current assets at March 31, 1996 were $737,000 compared with $590,000 at December 31, 1995, an increase of $147,000. This increase resulted primarily from an increase in interest receivables related to the Company's investment portfolio, and prepaid insurance. Current liabilities were $3,499,000 at March 31, 1996 compared with $2,868,000 at December 31, 1995. This increase was primarily due to an increase in alprostadil purchases in 1996. Capital expenditures in the three months ended March 31, 1996 were $499,000 compared with $974,000 for the same period ended March 31, 1995. Capital expenditures during the period in 1996 and 1995 consisted primarily of manufacturing and quality control equipment. Capital expenditures were higher in 1995 due to the construction of the Company's dedicated manufacturing and testing space within the Paco facility in Lakewood, New Jersey. Major capital expenditures over the next two years are likely to include a Company owned manufacturing facility in Europe, expansion of its current facility in the United States and establishing a research and quality control laboratory. Cash used in operations in 1995 was $21,539,000 compared with $12,643,000 in 1994. The increased use of cash was primarily due to a net loss of $22,811,000 in 1995 compared with a net loss of $14,864,000 in 1994. Prepaid and other current assets at December 31, 1995 were $590,000 compared with $555,000 at December 31, 1994, an increase of $35,000. This increase resulted primarily from an increase in interest receivables related to the Company's investment portfolio. Current liabilities were $2,868,000 at December 31, 1995 compared with $2,714,000 at December 31, 1994. This increase was primarily due to an increase in expenditures in 1995. Capital expenditures in 1995 were $3,148,000 compared with $787,000 in 1994. In 1995, the Company constructed and equipped approximately 6,000 square feet of manufacturing and testing space within Paco. Capital expenditures in 1995 consisted primarily of manufacturing, quality control and laboratory equipment. In 1995, the Company implemented an international product distribution strategy for VIVUS products. Implementation included the transfer of international product marketing rights to VIVUS International Limited in a taxable transaction. The transfer of rights and related allocation of research and development costs resulted in the current utilization of $29,467,000 of the Company's net operating loss carryforward. 18 20 The Company expects to incur substantial additional costs, including expenses related to its marketing and sales organization, a second manufacturing plant and expansion of the Company's existing plant, new product preclinical and clinical costs, ongoing research and development activities and general corporate purposes. The Company anticipates that its existing capital resources and the proceeds from this offering will be sufficient to support the Company's operations through commercial introduction of MUSE (alprostadil) in the United States and Europe but may not be sufficient for the introduction of any additional future products. While the Company believes its NDA filing was substantially complete, the Company may have to conduct additional studies or clinical trials in order to obtain regulatory approval of MUSE (alprostadil). Accordingly, the Company anticipates that it may be required to issue additional equity or debt securities and may use other financing sources including, but not limited to, corporate alliances and lease financings to fund the future development and possible commercial launch of its products. The sale of additional equity securities can be expected to result in additional dilution to the Company's stockholders. There can be no assurance that such funds will be available on terms satisfactory to the Company, or at all. Failure to obtain adequate funding could cause a delay or cessation of the Company's product development and marketing efforts and would have a material adverse effect upon the Company's business, financial condition and results of operations. The Company's working capital and additional funding requirements will depend upon numerous factors, including: (i) the ability to obtain and timing and costs of obtaining regulatory approvals; (ii) the level of resources that the Company devotes to sales and marketing capabilities; (iii) the level of resources that the Company devotes to expanding manufacturing capacity; (iv) the activities of competitors; (v) the progress of the Company's research and development programs; (vi) the timing and results of preclinical testing and clinical trials; and (vii) technological advances. 19 21 BUSINESS The following Business section contains forward-looking statements that involve risks and uncertainties. The Company's actual results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including those set forth under "Risk Factors" and elsewhere in this Prospectus. VIVUS is a leader in the development of advanced therapeutic systems for the treatment of erectile dysfunction. Erectile dysfunction, commonly referred to as impotence is the inability to achieve and maintain an erection of sufficient rigidity for sexual intercourse. The Company's transurethral system for erection is a non-invasive, easy to use system that delivers pharmacologic agents topically to the urethral lining. In March 1996, the Company submitted an NDA to the FDA for its anticipated first product, MUSE (alprostadil). The FDA accepted the Company's filing for priority review. The Company believes that MUSE (alprostadil), if approved by the FDA and foreign regulatory bodies, could become first line therapy for erectile dysfunction. If required approvals are received, the Company intends to market and sell its products initially through a direct sales force in the United States and to distribute its products in foreign markets through distribution, co-promotion or license agreements with corporate partners. In February 1996, the Company entered into an agreement with Cardinal that provides that Cardinal will fulfill the Company's orders and warehouse its products. In May 1996, the Company completed a marketing agreement with Astra to distribute the Company's products in Europe, South America, Central America, Australia and New Zealand. As consideration for execution of the marketing agreement, Astra will pay the Company $10 million in June 1996. The Company will be paid up to an additional $20 million in the event it achieves certain milestones. Astra has agreed to purchase product from the Company for resale into the above mentioned markets. BACKGROUND Erectile dysfunction results from (i) an inadequate supply of blood to the penis, (ii) a failure to relax the smooth muscle tissue in the penis so it can become engorged with blood or (iii) a failure to retain blood in the penis. Blood is carried to the penis in two large arteries that terminate in a maze of blood vessels contained in the three erectile bodies of the penis, the corpus spongiosum which surrounds the urethra and two corpora cavernosa. Smooth muscle tissue surrounds each individual blood vessel in the erectile bodies. When the penis is flaccid, the smooth muscle tissue is in a contracted state, which constricts the blood vessels resulting in reduced blood flow. During stimulation, a signal is sent to nerve endings in the penis that causes the smooth muscle tissue to relax. This relaxation allows the blood vessels to expand and, as arterial blood fills the erectile bodies, the penis becomes engorged with blood and erect. As the erectile bodies expand, the venous outflow of blood is restricted so that the erection can be maintained. [ILLUSTRATION] 20 22 Causes of Erectile Dysfunction Historically, psychological factors were considered the primary cause of erectile dysfunction. It is now widely understood that a substantial majority of all cases have a physiological cause. The Company believes that therapeutic treatments of erectile dysfunction can be effective, whether the cause is psychological or physiological. The primary physiological causes of erectile dysfunction fall into the following general categories: Vascular Diseases. Atherosclerosis, hypertension and other diseases can impede or obstruct the flow of blood to the penis. Neurological Diseases. Multiple sclerosis, Parkinson's disease and other diseases can interrupt nerve impulses to the penis. Diabetes. Diabetes mellitus can alter both nerve function and vascular flow, inhibiting the ability to achieve an erection. Prescription Drugs. Certain antihypertensive and cardiac medications, as well as a number of other prescription drugs, can affect nerve function in the penis by altering neurotransmitter levels. Spinal Injury. Injury to the spinal column can interrupt nerve impulses from the spinal cord to the penis. Pelvic Surgery. Radical prostatectomies, cystoprostatectomies and colectomies may traumatize or cut nerves or blood vessels to the penis. Other Causes. Hormonal imbalance, renal failure and dialysis, and drug and substance abuse (particularly smoking) can also impair the neurovascular system and cause erectile dysfunction. Market Size Based on a published study of more than 1,200 men in Massachusetts, the Company estimates that over 30% of males in the United States between the ages of 40 to 70 suffer from moderate to complete erectile dysfunction. The Company believes that similar rates prevail outside the United States. A recent estimate from the NIH Consensus Statement on Impotence (1992) suggests that the number of United States men with erectile dysfunction may be 10 to 20 million. The rate of erectile dysfunction increases significantly with age. Current Therapies Despite the detrimental effect erectile dysfunction may have on a couple's quality of life, the Company believes that, due in part to the limitations of current therapies, a large number of men suffering from erectile dysfunction currently do not seek medical treatment. The primary physiological therapies currently utilized for the treatment of erectile dysfunction are: Needle Injection Therapy. This form of treatment involves the needle injection of pharmacologic agents directly into the penis. These agents are generally combinations of vasoactive compounds such as alprostadil, phentolamine and papaverine. This form of treatment requires a prescription and instruction from a health care professional on self-injection. Side effects may include pain associated with injection and local pain and aching, priapism (persistent prolonged erections), fibrosis (build-up of scar tissue), and bleeding. Vacuum Constriction Devices. This form of treatment involves the use of a mechanical system that creates a vacuum around the penis, causing the erectile bodies to fill with blood. A constriction band is then placed around the base of the penis to impede blood drainage and maintain the erection. Vacuum constriction devices are large, mechanical devices that can be unwieldy and somewhat difficult to use. In addition, the erection may not seem natural since only the part of the penis beyond the constriction band is rigid, and the penis can become cold and discolored due to the constriction of blood flow. Complications encountered by some users of vacuum constriction devices include pain and difficulty ejaculating. 21 23 Penile Implants. This therapy involves the surgical implantation of a semi-rigid, rigid or inflatable device into the penile structure to mechanically simulate an erection. In addition to the risks associated with surgical procedures, there is a significant rate of complication with implants such as infection and mechanical failure of the device. This may necessitate a second surgical procedure to remove or reposition the device. In addition, due to the scarring associated with the implant procedure, the patient may no longer be a viable candidate for subsequent less radical therapies. Oral Medications. Yohimbine is the primary oral medication currently prescribed in the United States for the treatment of erectile dysfunction. While easily administered, yohimbine must be taken multiple times daily and may cause irritability, sweating, nausea and possibly hypertension. The Company believes that, for patients with physiologic erectile dysfunction, the efficacy of currently available oral medications is not significantly greater than placebo. The Company is aware of several oral medications that are currently under development, which, if approved, may be more effective than currently available oral medications. THE VIVUS SOLUTION VIVUS intends to address the significant market opportunity for erectile dysfunction therapy with its transurethral system for erection. The Company's transurethral system for erection represents a unique approach to treating erectile dysfunction and is based on the discovery that the urethra, although an excretory duct, can absorb certain pharmacologic agents into the surrounding erectile tissues. The Company believes that MUSE (alprostadil), if approved, could become first line therapy and increase the number of men who seek and receive treatment for erectile dysfunction. The Company's transurethral system for erection is designed to overcome the limitations of current therapies through its unique product attributes: Ease of Administration. The Company's transurethral system for erection is easy to use with minimal instruction, unlike needle injection therapy which requires precise injection into a corpus cavernosum. Non-invasive. The Company's transurethral system for erection utilizes urethral delivery, permitting topical application to the urethral mucosa. Discreet. The Company's transurethral system for erection utilizes a small, easily carried, single-use disposable applicator that can be discreetly applied and is easily integrated into the normal sexual life of the patient. Administration takes less than a minute. Quality of Erection. The Company's transurethral system for erection therapy mimics the normal vasoactive process, producing an erection which is more natural than those resulting from needle injection therapy, vacuum constriction devices or penile implants. Cost-competitive. Although the price for the Company's products has not been established, the Company anticipates that it will be a competitively priced therapy. Minimal Side Effects. The Company believes that therapy with MUSE (alprostadil) will result in fewer, less severe side effects than needle injection therapy and penile implants. 22 24 THE TRANSURETHRAL SYSTEM FOR ERECTION Administration. Administration of the transurethral system for erection is an easy and painless procedure. The end of the applicator is less than half the diameter of a man's urine stream and is inserted approximately three centimeters into the urethra. To use the transurethral system for erection, a patient urinates, shakes the penis to remove excess urine, inserts the transurethral system for erection into the urethra, releases the medication and then rolls the penis between the hands for 10 seconds to distribute the medication. [ILLUSTRATION] The application process takes less than a minute. Once administered, the pharmacologic agent dissolves in the small amount of urine which remains in the urethra. The pharmacologic agent is absorbed by the urethral mucosa and moves across the adjacent tissue and into the erectile bodies. When successful, an erection is produced within 15 minutes of administration and lasts approximately 30-60 minutes. Many patients experience mild and transient penile pain, urethral burning and/or local aching after administration and during intercourse. Initial Pharmacologic Agent. Alprostadil is the first pharmacologic agent anticipated for use in the transurethral system for erection. Alprostadil is the generic name for the synthetic version of prostaglandin E(1), a naturally occurring vasodilator present throughout the body and at high levels in seminal fluid. Alprostadil received FDA approval in 1981 for preoperative management of newborns with congenital heart defects. The Company believes that alprostadil has been widely prescribed for needle injection therapy of erectile dysfunction for years, even though it was only recently approved by the FDA for such use in July 1995. The Company has developed a formulation of alprostadil for the transurethral system for erection that enables it to quickly dissolve in the urine present in the urethra and pass through the adjacent corpus spongiosum and into the corpora cavernosa. Other Pharmacologic Agents. The Company is also engaged in the evaluation and development of additional pharmacologic agents to treat erectile dysfunction either alone or in combination with other agents. One such agent is prazosin, a generic alpha-blocker that can be delivered by the Company's transurethral system for erection, both alone and in conjunction with alprostadil. The Company has several other product candidates in preclinical development. THE VIVUS STRATEGY The Company's objective is to become the leading developer, manufacturer and supplier of products for the treatment of erectile dysfunction. The Company is pursuing this objective with the following strategies: Facilitate Clinical Development and Regulatory Review. The Company has sought and will continue to seek additional pharmacologic agents suitable for transurethral delivery for which significant safety data already exists. The Company believes that such agents may progress more rapidly through the clinical development and regulatory process. Expand the Market. The Company is seeking to increase the number of men receiving treatment for erectile dysfunction by developing safe, effective, discreet, easy to use, non-invasive products and by heightening physician and consumer awareness of erectile dysfunction through education. 23 25 Maintain Proprietary Technology. The Company has sought and will continue to seek a strong proprietary position for the Company's transurethral system for erection by pursuing patent protection in the United States and key international countries. Develop Novel Pharmacologic Agents. The Company is engaged in the research and development of and may seek to license novel pharmacologic agents that may provide an enhanced therapeutic benefit in the treatment of erectile dysfunction, either alone or in combination with other agents. Achieve Broad Distribution. The Company intends to market and sell its products initially through a direct sales force in the United States and to distribute its products in foreign markets through distribution, co-promotion or license agreements with corporate partners. In May 1996, the Company completed a marketing agreement with Astra to distribute its products in Europe, South America, Central America, Australia and New Zealand. CLINICAL STUDIES In March 1996, the Company submitted an NDA for its anticipated first product, MUSE (alprostadil). The NDA submission utilized information from the Company's clinical trials, which are depicted in the following chart and discussed below. ILLUSTRATION In July 1992, the Company filed an Investigational New Drug ("IND") application with the FDA. The IND application covered the use of the transurethral system for erection to deliver alprostadil and prazosin, either alone or in combination, for the treatment of erectile dysfunction. Under the IND, the Company has established 83 study sites and to date has enrolled and treated more than 1,950 men. In early 1994, the Company completed a Phase II/III Dose Ranging study that enrolled and treated 234 patients. The goal of this clinical trial was to examine the safety and efficacy of MUSE (alprostadil), prazosin and MUSE (alprostadil) in combination with prazosin at several dosage levels. The primary efficacy endpoint of the Dose Ranging study was the patient achieving penile rigidity or full enlargement. 24 26 Based upon the results of this study, the Company chose alprostadil as its initial pharmaclogic agent due to its safety and efficacy profile. Patients in the Dose Ranging study suffered from erectile dysfunction for an average period of 48 months prior to enrollment. More than 50 percent of the patients suffered from erectile dysfunction for a period of 36 months or more prior to enrollment. The results of this study showed that each dose of MUSE (alprostadil) (125, 250, 500 and 1000 mcg) was significantly better than placebo in achieving an erection. More than 52 percent of men treated with MUSE (alprostadil) in the study achieved penile rigidity and/or full penile enlargement, compared to 2.6 percent of men treated with placebo. The Company's transurethral system for erection was also rated as easy to use. The principal side effects of therapy with MUSE (alprostadil) were mild to moderate transient penile/perineal discomfort (experienced by 21 percent to 42 percent of patients depending upon dosage level) and moderate to severe decreases in blood pressure (experienced by one percent to four percent of patients depending upon dosage level). The Company believes that these data demonstrate preliminary efficacy and safety of transurethrally administered alprostadil in men with longstanding erectile dysfunction. In addition, several of the low-dose combinations of alprostadil and prazosin delivered by the Company's transurethal system for erection appeared to demonstrate preliminary safety and efficacy. In early 1995, the Company completed a Phase III Quality of Life study that enrolled and treated 539 patients. Upon completion of the Dose Ranging and Quality of Life studies, certain patients continued treatment by enrolling in a pivotal Phase III Maintenance study that was completed in mid-1995. Two additional pivotal Phase III Confirmatory studies began enrollment in mid-1994 and completed their enrollment with over 990 patients at 58 study sites throughout the United States. A similar European Confirmatory study was performed at 13 study sites in five European countries. A separate study was also concluded at two sites in Mexico. The Confirmatory studies were designed to further demonstrate the safety and efficacy of MUSE (alprostadil). The purpose of these studies was to examine the long-term efficacy and safety of the product in a large group of patient couples. The primary efficacy endpoint of the Confirmatory studies was the ability of the patient and his partner to engage in sexual intercourse. All of the Company's Phase III studies were prospective, double-blind, placebo-controlled trials. In mid-1995, the Company completed its Phase III Confirmatory studies for MUSE (alprostadil). Of participants using MUSE (alprostadil) 64.9 percent reported successful intercourse at least once versus 18.6 percent receiving placebo. Of all active doses administered, 50.2 percent resulted in intercourse, compared to 10.4 percent of placebo doses. No increased risk of serious adverse events due to MUSE (alprostadil) was found, and there were no reports of priapism (persistent abnormal erection) or penile scarring. Eighty-eight(88) percent of patient couples that commenced the pivotal Phase III Confirmation Study completed it. The most common side effect reported was mild and transient penile pain, and less than one percent of participants discontinued use due to discomfort. In patients who responded to treatment with MUSE (alprostadil) there was a statistically significant improvement in the patient's perception of his emotional well-being (p < 0.004) and in his relationship with his partner (p < 0.001) compared to patients treated with placebo. From the partner's perspective, there also was a statistically significant improvement in her relationship with the patient (p < 0.001) compared to partners in the placebo group. During the NDA approval process, the Company will continue open label Extended Maintenance studies for those patients electing to continue treatment. The Company's ongoing clinical trials will evaluate the long-term safety of MUSE (alprostadil) for both the patient and his partner. Additional adverse side effects may arise during the course of ongoing clinical trials. There can be no assurance that MUSE (alprostadil) will be shown to be safe or efficacious or that FDA approval will be obtained. The FDA may require limitations on use or warnings that limit demand for the Company's products. See "Risk Factors -- Dependence on The Transurethral System for Erection" and "-- Government Regulation and Uncertainty of Product Approvals." Because alprostadil and prazosin have each been approved for other indications, the FDA and other regulatory authorities allowed the Company to commence clinical trials with limited preclinical safety studies. However, the Company conducted additional safety studies, concurrent with its pivotal trials, to further define the safety profile of alprostadil. These studies included pharmacokinetic, in vitro mutagenicity, developmental reproductive and repeat-dose toxicology studies. The Company included the results of these studies in the 25 27 NDA for MUSE (alprostadil). Additional safety studies may be required by the FDA or other regulatory agencies. RESEARCH AND DEVELOPMENT The Company's research and development is focused on the evaluation of pharmacologic agents capable of producing erections through various mechanisms and the testing of promising agents, both alone and in combination with other agents, in the Company's transurethral system for erection. Classes of agents causing erections by relaxing smooth muscle tissue include nitric oxide donors, potassium channel activators, phosphodiesterase inhibitors and other vasodilators (such as alprostadil). Classes of agents that contribute to an erection by delaying smooth muscle contraction include alpha blockers (such as prazosin) and calcium channel blockers. The Company has evaluated several alpha blocking agents and nitric oxide donors. In addition, the Company has begun the evaluation of a phosphodiesterase inhibitor and certain calcium channel blockers and potassium channel activators. As part of the Company's strategy, the Company focuses its research and development on pharmacologic agents for which significant safety data already exists. The Company believes that such agents may progress more rapidly through clinical development and the regulatory process. The Company is currently developing its potential second product, an alprostadil and prazosin combination for use with its transurethral system for erection. The Company expects to begin a Phase III multi-center trial for this product in the second half of 1996. The Company will be required to undertake time-consuming and costly development activities and seek FDA approval for this product. There can be no assurance that product development will ever be successfully completed, that NDAs, if applied for, will be granted by the FDA on a timely basis, if at all, or that the products will ever achieve commercial acceptance. Failure by the Company to develop, obtain necessary regulatory approval for or to successfully market new products could have a material adverse effect on the Company's business, financial condition and results of operations. SALES AND MARKETING The Company has no experience in the sale, marketing and distribution of pharmaceutical products. Upon receiving required approvals, the Company intends to market and sell its products initially through a direct sales force in the United States. In order to market its products directly, the Company must develop a sales force with the proper technical expertise. There can be no assurance that the Company will be able to build a sales force, or that the Company's sales and marketing efforts will be successful. In February 1996, the Company entered into an agreement with a wholly-owned subsidiary of Cardinal Health, Inc. ("Cardinal"). Under this agreement, Cardinal will warehouse the Company's finished goods, take customer orders, pack and ship its product, invoice customers and collect related receivables. The Company will also have access to Cardinal's information systems that support these functions. As a result of this agreement with Cardinal, the Company is dependent on Cardinal's efforts to fulfill orders and warehouse its products effectively. There can be no assurance that such efforts will be successful. In May 1996, the Company completed a marketing agreement with Astra to distribute the Company's products in Europe, South America, Central America, Australia and New Zealand. As consideration for execution of the marketing agreement, Astra will pay the Company $10 million in June 1996. The Company will be paid up to an additional $20 million in the event it achieves certain milestones. The Company and Astra will jointly build a specialty sales organization within Astra called "ASTRA/VIVUS," to promote the product in certain European markets, including the United Kingdom, France and Germany. The Company retains the right to take over this specialty organization and co-promote the product in these markets after a certain period of time. Astra has agreed to purchase product from the Company for resale into the above mentioned markets. The marketing agreement does not have minimum purchase commitments, and Astra may take up to twelve months to introduce a product in a given country following regulatory approval in such country. As a result of this marketing agreement with Astra, the Company is dependent on Astra's efforts to market, distribute and sell the Company's products effectively in the above mentioned markets. There can be no assurance that such efforts will be successful. 26 28 The Company intends to market and sell its products in other foreign markets through distribution, co-promotion or license agreements with corporate partners. To the extent that the Company enters into distribution, co-promotion or license agreements for the sale of its products, the Company will be dependent upon the efforts of third parties. These third parties may have other commitments, and there can be no assurance that they will commit the necessary resources to effectively market, distribute and sell the Company's products. See "Risk Factors -- Limited Sales and Marketing Experience and Dependence on Third Parties." RAW MATERIALS AND MANUFACTURING To date, the Company has obtained its supply of alprostadil from two sources. The first is Spolana pursuant to a supply agreement that expires at the end of 1996. In January 1996, the Company completed a long-term alprostadil supply agreement with Chinoin. Chinoin is the Hungarian subsidiary of the French pharmaceutical company Sanofi Winthrop. The Company's sources of supply will be subject to GMP requirements of the FDA. While the Company believes it has taken steps to ensure GMP compliance, there can be no assurance FDA approval will be received. Alprostadil, a generic drug, is extremely difficult to manufacture and is only available to the Company from a limited number of other suppliers, none of which currently produce it in commercial quantities. While the Company is seeking additional sources of alprostadil, there can be no assurance that it will be able to identify and qualify such sources. The Company is required to identify its suppliers to the FDA, and the FDA may require additional clinical trials or other studies prior to accepting any new supplier. Unless the Company secures and qualifies additional sources of alprostadil, it will be entirely dependent upon Spolana and Chinoin for the delivery of alprostadil. If interruptions in the supply of alprostadil were to occur for any reason, including a decision by Spolana and/or Chinoin to discontinue manufacturing, political unrest, labor disputes, or a failure of Spolana and/or Chinoin to follow regulatory guidelines, the development and commercial marketing of MUSE (alprostadil) and other potential products could be delayed or prevented. An interruption in the Company's supply of alprostadil would have a material adverse effect on the Company's business, financial condition and results of operations. See "Risk Factors -- Dependence on Dual Source of Supply." The Company has only limited experience in manufacturing MUSE (alprostadil) and has not yet manufactured it in commercial quantities. As a result, the Company has no experience manufacturing its product in volumes necessary for the Company to achieve significant commercial sales, and there can be no assurance that reliable, high-volume manufacturing can be achieved at commercially reasonable cost. If the Company encounters any manufacturing difficulties, including problems involving production yields, quality control and assurance, supplies of components or raw materials or shortages of qualified personnel, it could have a material adverse effect on its business, financial condition and results of operations. The formulation, filling, packaging and testing of MUSE (alprostadil) is performed by Paco at its facility in Lakewood, New Jersey. In June 1995, the Company completed construction of its approximately 6,000 square feet of dedicated manufacturing and testing space within Paco's facility. The Company will be required to expand its manufacturing and testing space at Paco or to find additional facilities, if regulatory approval is obtained and MUSE (alprostadil) is successfully introduced. The Company also intends to establish a Company owned and operated manufacturing facility in Europe. Until the Company develops an in-house manufacturing capability or is able to identify and qualify alternative contract manufacturers, it will be entirely dependent upon Paco for the manufacture of its products. As part of the approval process for the Company's NDA, Paco will be subject to audit by the FDA as part of its GMP inspection. There can be no assurance that the facility will receive the necessary GMP approval. There can be no assurance that the Company's reliance on Paco or others for the manufacture of its products will not result in problems with product supply, and there can be no assurance that the Company will be able to establish a second manufacturing facility or expand its existing facility at Paco. Interruptions in the availability of products could delay or prevent the development and commercial marketing of MUSE (alprostadil) and other potential products and would have a material adverse effect on the Company's business, financial condition and results of operations. See "Risk Factors -- Limited Manufacturing Experience and Dependence on Sole Contract Manufacturer." 27 29 The Company obtains the necessary raw materials and components for the manufacture of MUSE (alprostadil) from third parties. The Company currently contracts with contract manufacturing organizations that are required to comply with strict standards established by the Company. Contract manufacturers are required by the Federal Food, Drug, and Cosmetic Act, as amended, and by FDA regulations to follow GMP. The Company is required to identify its suppliers to the FDA and is dependent upon its contract manufacturers and its suppliers to comply with the Company's specifications and, as required, GMP or similar standards imposed by foreign regulators. Although the Company has taken all actions that it believes are reasonable to assure that its contract manufacturers and suppliers are in compliance with these requirements, there can be no assurance that the FDA, or a state, local or foreign regulator will not take action against a contract manufacturer or supplier found to be violating applicable regulations. Such an action could have a material adverse effect on the Company's business, financial condition and results of operation. See "Risk Factors -- Government Regulation and Uncertainty of Product Approvals." LICENSED PATENTS AND PROPRIETARY RIGHTS The Company's policy is to aggressively maintain its patent protection and to enforce all of its intellectual property rights. The Company is the exclusive licensee of United States and Canadian patents originally filed in the name of Dr. Gene Voss. These patents claim methods of treating erectile dysfunction by the topical application of an ointment containing a vasodilator. There are also claims to methods of treatment involving the insertion of a catheter into the urethra to deliver vasodilators. The Company is the exclusive licensee of patents and patent applications filed in the name of Dr. Nils Kock in numerous countries. Patents have issued in Australia, Canada, New Zealand, Sweden, South Africa and Europe (Austria, Belgium, Germany, France, Great Britain, Ireland, Italy, Luxembourg, Netherlands, Sweden, Greece and Spain). Patent applications are pending in Denmark, Finland, Japan and the United States. The European patents claim compositions for the treatment of erectile dysfunction through the urethra of certain active substances including alpha-receptor blockers, vasoactive polypeptides, prostaglandins or nitroglycerine dispersed in a hydrophilic vehicle. A competitor has filed a patent opposition against this patent with the European Patent Office. The Company is vigorously defending this patent, however, an adverse decision could affect the Company's ability, based on its patent rights, to prevent potential competition in Europe. The Company is the exclusive assignee of two United States patents and divisional patent applications from Alza Corporation ("Alza"), covering inventions of Dr. Virgil Place made while he was an employee of Alza. The patents and patent applications describe dosage forms for administering a therapeutic agent to the urethra, methods for treating erectile dysfunction and specific drug formulations that can be delivered transurethrally for the treatment of erectile dysfunction. Five additional divisional or continuation applications claiming subject matter disclosed but not claimed in the issued patents or applications were filed in the United States on June 7, 1995. Patent applications filed before June 8, 1995, if approved, will have a patent life of 17 years from the patent issue date. Patent applications filed after June 8, 1995, if approved, will have a patent life of 20 years from the filing date. Foreign patents have issued in South Africa and Australia and foreign applications are pending in Canada, Finland, Ireland, Mexico, Portugal, New Zealand, Japan, South Korea, Norway and Europe (Austria, Belgium, Switzerland, Germany, Denmark, Spain, France, United Kingdom, Italy, Luxembourg, Netherlands, Sweden and Greece). The Company's license and assignment agreements for these patents and patent applications are royalty bearing and do not expire until the licensed patents expire. These license and assignment agreements provide that the Company may assume responsibility for the maintenance and prosecution of the patents and to bring infringement actions. In addition, the Company filed four patent applications in the United States and one patent cooperation treaty application in 1995 and two in 1996. These patents further address the treatment, diagnosis and/or prevention of erectile dysfunction, and one covers a chemical synthesis of a drug substance for erectile dysfunction. The Company is currently prosecuting these recently filed patents. 28 30 The Company's success will depend in large part on the strength of its current and future patent position relating to the transurethral delivery of pharmacologic agents for the treatment of erectile dysfunction. The Company's patent position, like other pharmaceutical companies, is highly uncertain and involves complex legal and factual questions. Claims made under patent applications may be denied or significantly narrowed and the issued patents may not provide significant commercial protection to the Company. The Company could incur substantial costs in proceedings before the United States Patent Office, including interference proceedings. These proceedings could also result in adverse decisions as to the priority of the Company's licensed or assigned inventions. There is no assurance that the Company's patents will not be challenged or designed around by others. The Company is aware of a patent application involving the transurethral application of prostaglandin E2 in the United States. The corresponding application in Europe has been abandoned. Failure of the Company's licensed patents to block issuance of such patent could have a material adverse effect on the Company's business, financial condition and results of operations. There can be no assurance that the Company's products do not or will not infringe on the patent or proprietary rights of others. A patent opposition to the Company's exclusively licensed European patents has been filed with the European Patent Office. The Company is vigorously defending the patents, however an adverse decision could affect the Company's ability, based on its patent rights, to limit potential competition in Europe. The Company may be required to obtain additional licenses to the patents, patent applications or other proprietary rights of others. There can be no assurance that any such licenses would be made available on terms acceptable to the Company, if at all. If the Company does not obtain such licenses, it could encounter delays in product introductions while it attempts to design around such patents, or the development, manufacture or sale of products requiring such licenses could be precluded. The Company believes there will continue to be significant litigation in the pharmaceutical industry regarding patent and other intellectual property rights. A former consultant to the Company has claimed that he is the inventor of certain technology disclosed in one of the Company's patents. The former consultant further claims that the Company defrauded him by allegedly failing to inform him that it intended to use and patent this technology and by failing to compensate him for the technology in the manner allegedly promised. The Company has filed a declaratory relief action against the former consultant in the United States District Court for the Northern District of California that seeks to determine the Company's rights with respect to the allegations. The former consultant has not yet been served in the proceeding. In a separate matter, the licensors in an agreement by which the Company acquired a patent license have recently filed a lawsuit alleging that they were defrauded in connection with the renegotiation of the license agreement between the Company and the licensors. In addition to monetary damages, the licensors seek to return to the terms of the original license agreement. The Company has conducted a review of the circumstances surrounding these two matters and believes that the allegations are without merit. Although the Company believes that it should prevail, the uncertainties inherent in litigation prevent the Company from giving any assurances about the outcome of such litigation. See "-- Litigation." The Company also relies on trade secrets and other unpatented proprietary technology. No assurance can be given that the Company can meaningfully protect its rights in such unpatented proprietary technology or that others will not independently develop substantially equivalent proprietary products and processes or otherwise gain access to the Company's proprietary technology. The Company seeks to protect its trade secrets and proprietary know-how, in part, with confidentiality agreements with employees and consultants. There can be no assurance that these agreements will not be breached, that the Company will have adequate remedies for any breach or that the Company's trade secrets will not otherwise become known or be independently developed by competitors. In addition, protracted and costly litigation may be necessary to enforce and determine the scope and validity of the Company's proprietary rights. See "Risk Factors -- Proprietary Rights and Risk of Litigation." COMPETITION Competition in the pharmaceutical and medical products industries is intense and is characterized by extensive research efforts and rapid technological progress. Certain treatments for erectile dysfunction exist, such as needle injection therapy, vacuum constriction devices, penile implants and oral medications, and the 29 31 manufacturers of these products will continue to improve these therapies. In July 1995, the FDA approved the use of alprostadil in Upjohn's needle injection therapy product for erectile dysfunction. Previously, Upjohn had obtained approval in a number of European countries. Additional competitive therapies under development include an oral medication, Viagra, by Pfizer, Inc., which is currently in Phase III clinical trials. Other large pharmaceutical companies are also actively engaged in the development of therapies for the treatment of erectile dysfunction. These companies have substantially greater research and development capabilities as well as substantially greater marketing, financial and human resources than the Company. In addition, these companies have significantly greater experience than the Company in undertaking preclinical testing, human clinical trials and other regulatory approval procedures. There are also small companies, academic institutions, governmental agencies and other research organizations that are conducting research in the area of erectile dysfunction. For instance, Zonagen, Inc. and Pentech Pharmaceutical, Inc. have oral medications under development. These entities may also market commercial products either on their own or through collaborative efforts. The Company's competitors may develop technologies and products that are available for sale prior to the Company's products or that are more effective than those being developed by the Company. Such developments would render the Company's products less competitive or possibly obsolete. If the Company is permitted to commence commercial sales of products, it will also be competing with respect to marketing capabilities and manufacturing efficiency, areas in which it has limited experience. See "Risk Factors -- Intense Competition." GOVERNMENT REGULATION The production and marketing of the Company's proposed products and its research and development activities are subject to regulation for safety, effectiveness and quality by numerous governmental authorities in the United States and other countries. In the United States, drugs are subject to rigorous FDA regulation. The Federal Food, Drug, and Cosmetic Act, as amended, the regulations promulgated thereunder, and other federal and state statutes and regulations, govern, among other things, the testing, manufacture, safety, effectiveness, labeling, storage, record keeping, advertising and promotion of the Company's products. Product development and approval within this regulatory framework takes a number of years and involves the expenditure of substantial resources. The steps required before a pharmaceutical agent may be marketed in the United States include (i) preclinical laboratory tests, in vivo preclinical studies and formulation studies, (ii) the submission to the FDA of an IND application for human clinical testing, which must become effective before human clinical trials commence, (iii) adequate and well-controlled human clinical trials to establish the safety and effectiveness of the drug, (iv) the submission of an NDA to the FDA, and (v) the FDA approval of the NDA prior to any commercial sale or shipment of the drug. In addition to obtaining FDA approval for each product, each domestic drug manufacturing establishment must be registered with, and approved by, the FDA. Domestic manufacturing establishments are subject to biennial inspections by the FDA and must comply with GMP for both drugs and devices. To supply products for use in the United States, foreign manufacturing establishments must comply with GMP and are subject to periodic inspection by the FDA or by corresponding regulatory agencies in such countries under reciprocal agreements with the FDA. The Company's contract manufacturing site, located in New Jersey, must also be licensed by the State of New Jersey and must comply with New Jersey's separate regulatory requirements. Preclinical tests include laboratory evaluation of product chemistry and formulation, as well as animal studies to assess the potential safety and effectiveness of the product. Compounds must be adequately manufactured and preclinical safety tests must be conducted by laboratories that comply with FDA regulations. The results of the preclinical tests are submitted to the FDA as part of an IND and are reviewed by the FDA prior to the commencement of human clinical trials. There can be no assurance that submission of an IND will result in FDA authorization to commence clinical trials. Clinical trials involve the administration of the investigational new drug to patients, under the supervision of a qualified principal investigator. Clinical trials are conducted in accordance with Good Clinical Practices under protocols that detail the objectives of the study, the parameters to be used to monitor safety and the effectiveness criteria to be evaluated. Each protocol must be submitted to the FDA as part of the IND. 30 32 Further, each clinical study must be conducted under the auspices of an independent Institutional Review Board ("IRB") at the institution at which the study will be conducted. The IRB will consider, among other things, ethical factors, the safety of human subjects and the possible liability of the institution. Clinical trials are typically conducted in three sequential phases, but the phases may overlap. In Phase I, the initial introduction of the drug into healthy subjects, the drug is tested for safety, dosage tolerance, absorption, distribution, metabolism, excretion and pharmacodynamics (clinical pharmacology). Phase II involves studies in a limited patient population to (i) determine the effectiveness of the drug for specific, targeted indications, (ii) determine dosage tolerance and optimal dosage and (iii) identify possible adverse effects and safety risks. When a compound is found to be effective and to have an acceptable safety profile in Phase II evaluations, Phase III trials are undertaken to further evaluate clinical effectiveness and to further test for safety within an expanded patient population at geographically dispersed clinical study sites. There can be no assurance that Phase I, Phase II or Phase III testing will be completed within any specific time period, if at all, with respect to any of the Company's products subject to such testing. Furthermore, the Company or the FDA may suspend clinical trials at any time if it is believed that the patients are being exposed to an unacceptable health risk. See "Risk Factors -- Government Regulation and Uncertainty of Product Approvals." The results of the pharmaceutical development, preclinical studies and clinical studies are submitted to the FDA in the form of an NDA for approval of the marketing and commercial shipment of the drug. The testing and approval process is likely to require substantial time and effort and there can be no assurance that any approval will be granted on a timely basis, if at all. The FDA may deny an NDA if applicable regulatory criteria are not satisfied, require additional testing or information, or require postmarketing testing and surveillance to monitor the safety of the Company's products if they do not view the NDA as containing adequate evidence of the safety and effectiveness of the drug. Notwithstanding the submission of such data, the FDA may ultimately decide that the application does not satisfy its regulatory criteria for approval. Moreover, if regulatory approval of a drug is granted, such approval may entail limitations on the indicated uses for which it may be marketed. Finally, approvals may be withdrawn if compliance with regulatory standards is not maintained or if problems occur following initial marketing. For purposes of prioritizing the review of NDAs, FDA classifies drugs as either "priority review" or "standard review" products. A "priority review" drug is one that appears to represent a therapeutic advance over available therapy. This assessment is for FDA's review purposes only and does not represent the agency's views or predictions regarding a drug's ultimate value or how it will be received in the market. FDA can change a drug's classification during the review process. In connection with the Prescription Drug User Fee Act of 1992 (PDUFA), FDA has accepted a five-year goal, to be implemented by September 30, 1997, of acting on priority NDAs within six months of submission and on standard NDAs within 12 months of submission (major amendments received within three months of the action due date extend the date by three months). For these purposes, to "act on" an application does not necessarily mean to approve an NDA, but rather includes issuing an initial action letter indicating either that the application is approvable or that it is not approvable and listing the deficiencies that must be corrected. There are numerous "interim" review-time goals under PDUFA slated for implementation before 1997, but these do not treat priority and standard applications separately. Experience under PDUFA thus far has shown that, on average, priority applications have undergone somewhat shorter review periods than have standard applications before issuance of an initial action letter. However, the review period prior to an initial action letter and prior to final approval for any particular NDA will depend on many factors and may be considerably longer or shorter than the average, and there is no assurance that any particular NDA will in fact be approved by the FDA. Among the conditions for an NDA approval is the requirement that the prospective manufacturer's quality control and manufacturing procedures conform to GMP. In complying with standards set forth in these regulations, manufacturers must continue to expend time, money and effort in the area of production and quality control to ensure full technical compliance. 31 33 For clinical investigation and marketing in Europe, the Company also is subject to foreign regulatory requirements governing human clinical trials and marketing approval for drugs. The requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary widely for European countries both within and outside the European Union ("EU"). The Company's approach to the European regulatory process involved the identification of respected clinical investigators in the member states of the EU and other European countries to conduct clinical studies. The Company designed these studies to meet FDA, EU and other European countries' standards. Within the EU, while marketing authorizations must be supported by clinical trial data of a type and extent set out by EU directives and guidelines, the approval process for the commencement of clinical trials is just beginning to be harmonized by EU law, and still varies from country to country. The system for obtaining marketing authorizations within the EU changed on January 1, 1995. The new EU registration system is a dual one in which certain products, such as biotechnology and high-technology products and those containing new active substances, have access to a central regulatory system that provides registration throughout the entire EU. Other products will be registered by national authorities in individual EU member states, operating on a principle of mutual recognition. As far as possible, the Company's studies were designed to develop a regulatory package sufficient for multi-country approval in the European markets without the need to duplicate studies for individual country approvals. Outside the United States and Europe, the Company's ability to market a product is contingent upon receiving a marketing authorization from the appropriate regulatory authority. This foreign regulatory approval process includes all of the risks associated with FDA approval previously discussed. EMPLOYEES As of May 17, 1996 the Company employed 42 persons, of whom one is part-time. None of the Company's current employees is represented by a labor union or is the subject of a collective bargaining agreement. The Company believes that it maintains good relations with its employees. FACILITIES The Company currently occupies 16,507 square feet of administrative space in Menlo Park, California under a lease which expires in December 1997. The Company's facility serves as the principal site for administration, clinical trial management, regulatory affairs and monitoring of product production and quality control. The current facilities are expected to meet the Company's administration requirements through the term of the lease. In June 1995, the Company completed constructing and equipping to its specifications approximately 6,000 square feet of leased manufacturing and testing space within Paco's facility in Lakewood, New Jersey. The Company is currently subleasing 2,150 square feet of laboratory space in San Carlos, California under a sublease which expires in August 1996. The Company anticipates that it can renew this lease or that other space will be available. LITIGATION A former consultant to the Company has claimed that he is the inventor of certain technology disclosed in one of the Company's patents. The former consultant further claims that the Company defrauded him by allegedly failing to inform him that it intended to use and patent this technology, and by failing to compensate him for the technology in the manner allegedly promised. On May 28, 1996, the Company filed a complaint for declaratory judgment against the former consultant in the United States District Court for the Northern District of California, which seeks a declaration from the court that the former consultant is not an inventor of any of the technology disclosed in the patent. In a separate matter, on April 10, 1996, the licensors in an agreement by which the Company acquired a patent license filed a lawsuit in a Texas State court that alleges that they were defrauded in connection with the renegotiation of the license agreement between the Company and the licensors. On May 8, 1996 the action was removed to the United States District Court for the Western District of Texas. In addition to monetary damages, the licensors seek to return to the terms of the original license agreement. The Company has conducted a review of the circumstances surrounding these two matters 32 34 and believes that the allegations are without merit. Although the Company believes that it should prevail, the uncertainties inherent in litigation prevent the Company from giving any assurances about the outcome of such litigation.

LIMITATIONS ON LIABILITY AND INDEMNIFICATION MATTERS The Company's Certificate of Incorporation limits the liability of directors to the maximum extent permitted by Delaware law. Delaware law provides that directors of a corporation will not be personally liable for monetary damages for breach of their fiduciary duties as directors, except liability for (i) breach of their duty of loyalty to the corporation or its stockholders, (ii) acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) unlawful payments of dividends or unlawful stock repurchases or redemptions, or (iv) any transaction from which the director derived an improper personal benefit. Such limitation of liability does not apply to liabilities arising under the federal or state securities laws and does not affect the availability of equitable remedies such as injunctive relief or rescission. 35 37 The Company's Bylaws provide that the Company shall indemnify its directors and executive officers and may indemnify its other officers and employees and other agents to the fullest extent permitted by law. The Company believes that indemnification under its Bylaws covers at least negligence and gross negligence on the part of indemnified parties. The Company's Bylaws also permit it to secure insurance on behalf of any officer, director, employee or other agent for any liability arising out of his or her actions in such capacity, regardless of whether the Bylaws permit such indemnification. The Company has entered into agreements to indemnify its directors and executive officers, in addition to the indemnification provided for in the Company's Bylaws. These agreements, among other things, indemnify the Company's directors and executive officers for certain expenses (including attorneys' fees), judgments, fines and settlement amounts incurred by any such person in any action or proceeding, including any action by or in the right of the Company arising out of such person's services as a director or executive officer of the Company, any subsidiary of the Company or any other company or enterprise to which the person provides services at the request of the Company. The Company believes that these provisions and agreements are necessary to attract and retain qualified persons as directors and executive officers. There is certain pending and threatened litigation involving Leland F. Wilson and Virgil A. Place, each a director and officer of the Company, that may result in a claim for indemnification. See "Business -- Litigation." 36 38 UNDERWRITING The underwriters named below (the "Underwriters"), for whom PaineWebber Incorporated and Invemed Associates, Inc. are acting as representatives (the "Representatives"), have severally agreed, on the terms and subject to the conditions set forth in the Underwriting Agreement by and among the Company and the Underwriters (the "Underwriting Agreement"), to purchase from the Company, and the Company has agreed to sell to the Underwriters, the number of shares of Common Stock set forth opposite the name of such Underwriters below:
NUMBER UNDERWRITERS OF SHARES ---------------------------------------------------------------- --------- PaineWebber Incorporated........................................ Invemed Associates, Inc......................................... --------- Total................................................. 2,000,000 ========
The Underwriting Agreement provides that the obligations of the Underwriters to purchase the shares of Common Stock listed above are subject to certain conditions. The Underwriting Agreement also provides that the Underwriters are committed to purchase all of the shares of Common Stock offered hereby, if any are purchased (without consideration of any shares that may be purchased through the Underwriters' over-allotment option). The Representatives have advised the Company that the Underwriters propose to offer the shares of Common Stock to the public at the public offering price set forth on the cover of this Prospectus and to certain dealers at such price less a concession not in excess of $ per share, and that the Underwriters and such selected dealers may reallow a concession to other dealers not in excess of $ per share. After the public offering of the Common Stock, the public offering price, the concessions to selected dealers and reallowance to other dealers may be changed by the Representatives. The Company has granted the Underwriters an option, exercisable during the 30-day period after the date of this Prospectus, to purchase up to an additional 300,000 shares of Common Stock at the public offering price set forth on the cover page of this Prospectus, less the underwriting discounts and commissions. To the extent the Underwriters exercise such option, each of the Underwriters will become obligated, subject to certain conditions, to purchase such percentage of such additional shares of Common Stock as is approximately equal to the percentage of shares of Common Stock that it is obligated to purchase as shown in the table set forth above. The Underwriters may exercise such option only to cover over-allotments, if any, incurred in the sales of shares of Common Stock. The Company has agreed to indemnify the Underwriters against certain liabilities, including liabilities under the Securities Act, or to contribute to payments that the Underwriters may be required to make in respect thereof. The Company, its directors and executive officers and certain stockholders have agreed not to offer, sell, contract to sell, or grant any option to purchase or otherwise dispose of any shares of Common Stock owned by them prior to the expiration of 90 days from the date of this Prospectus, except (i) for shares of Common Stock offered hereby, (ii) with the prior written consent of PaineWebber Incorporated, and (iii) in the case of the Company, for the issuance of shares of Common Stock upon the exercise of options, or the grant of options to purchase shares of Common Stock. In connection with this offering, certain Underwriters and selling group members or their affiliates may engage in passive market making transactions in the Common Stock on the Nasdaq National Market in 37 39 accordance with Rule 10b-6A under the Exchange Act. Passive market making consists of, among other things, displaying bids on the Nasdaq National Market limited by the bid prices of independent market makers and making purchases limited by such prices and effected in response to order flow. Net purchases by a passive market maker on each day are limited to a specified percentage of the passive market maker's average daily trading volume in the Common Stock during a specified prior period, and all passive market making activity must be discontinued when such limit is reached. Passive market making may stabilize the market price of the Common Stock at a level above that which might otherwise prevail and, if commenced, may be discontinued at any time. As of the date of this Prospectus, Invemed Associates, Inc. and its affiliates beneficially own an aggregate of 199,172 shares of Common Stock (including up to 92,505 shares subject to outstanding warrants exercisable for Common Stock). LEGAL MATTERS The validity of the Common Stock offered hereby will be passed upon for the Company by Wilson Sonsini Goodrich & Rosati, P.C., Palo Alto, California. Certain legal matters relating to patents in connection with this offering will be passed on by Flehr Hohbach Test Albritton & Herbert, San Francisco, California. Pillsbury Madison & Sutro LLP, Menlo Park, California is acting as legal counsel for the Underwriters in connection with certain legal matters relating to the shares of Common Stock offered hereby.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS Section 145 of the Delaware General Corporation Law permits a corporation to include in its charter documents, and in agreements between the corporation and its directors and officers, provisions expanding the scope of indemnification beyond that specifically provided by the current law. Article VIII of the Registrant's Certificate of Incorporation provides for the indemnification of directors to the fullest extent permissible under Delaware law. Article VI of the Registrant's Bylaws provides for the indemnification of officers, directors and third parties acting on behalf of the corporation if such person acted in good faith and in a manner reasonably believed to be in and not opposed to the best interest of the corporation, and, with respect to any criminal action or proceeding, the indemnified party had no reason to believe his conduct was unlawful. The Registrant has entered into indemnification agreements with its directors and executive officers, in addition to indemnification provided for in the Registrant's Bylaws, and intends to enter into indemnification agreements with any new directors and executive officers in the future.

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 provisions described in Item 15, the Underwriting Agreement, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.

The undersigned Registrant undertakes; (1) that for purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus filed as part of the Registration Statement in reliance upon Rule 430A and contained in the 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 the Registration Statement as of the time it was declared effective; (2) that 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 in the initial bona fide offering thereof; and (3) to deliver or cause to be delivered with the prospectus, to each person to whom the prospectus is sent or given, the latest annual report to security holders that is incorporated by reference in the prospectus and furnished pursuant to and meeting the requirements of Rule 14a-3 or Rule 14c-3 under the Exchange Act, and, where interim financial information required to be presented by Article 3 of Regulation S-X are not set forth in the prospectus, to deliver, or cause to be delivered to each person to whom the prospectus is sent or given, the latest quarterly report that is specifically incorporated by reference in the prospectus to provide such interim financial information.

PAINEWEBBER INCORPORATED
INVEMED ASSOCIATES, INC.
  As Representatives of the
  several Underwriters
c/o PaineWebber Incorporated
  1285 Avenue of the Americas
  New York, New York 10019

Ladies and Gentlemen:

         VIVUS, Inc., a Delaware corporation (the "Company"), proposes to sell
an aggregate of 2,000,000 shares (the "Firm Shares") of the Company's Common
Stock, par value $0.001 per share (the "Common Stock"), to you and to the other
underwriters named in Schedule I (collectively, the "Underwriters"), for whom
you are acting as representatives (the "Representatives"). The Company has also
agreed to grant to you and the other Underwriters an option (the "Option") to
purchase up to an additional 300,000 shares of Common Stock (the "Option
Shares") on the terms and for the purposes set forth in Section 1(b). The Firm
Shares and the Option Shares are hereinafter collectively referred to as the
"Shares."

         The initial public offering price per share for the Shares and the
purchase price per share for the Shares to be paid by the several Underwriters
shall be agreed upon by the Company and the Representatives, acting on behalf of
the several Underwriters, and such agreement shall be set forth in a separate
written instrument substantially in the form of Exhibit A hereto (the "Price
Determination Agreement"). The Price Determination Agreement may take the form
of an exchange of any standard form of written telecommunication among the
Company and the Representatives and shall specify such applicable information as
is indicated in Exhibit A hereto. The offering of the Shares will be governed by
this Agreement, as supplemented by the Price Determination Agreement. From and
after the date of the execution and delivery of the Price Determination
Agreement, this Agreement shall be deemed to incorporate, and, unless the
context otherwise indicates, all references contained herein to "this Agreement"
and to the phrase "herein" shall be deemed to include the Price Determination
Agreement.

         The Company confirms as follows its agreements with the Representatives
and the several other Underwriters.

         1. Agreement to Sell and Purchase.

         (a) On the basis of the representations, warranties and agreements of
the Company herein contained and subject to all the terms and conditions of this
Agreement, the Company agrees to sell to each Underwriter named below, and each
Underwriter, severally and not jointly, agrees to purchase from the Company at
the purchase price per share for the Firm Shares to be agreed upon by the
Representatives and the Company in accordance with Section 1(c) or 1(d) and set
forth in the Price Determination Agreement, the number of Firm Shares set forth
opposite the name of such Underwriter in Schedule I, plus such additional

                                       -1-
   2
number of Firm Shares which such Underwriter may become obligated to purchase
pursuant to Section 8 hereof. Schedule I may be attached to the Price
Determination Agreement.

         (b) Subject to all the terms and conditions of this Agreement, the
Company grants the Option to the several Underwriters to purchase, severally and
not jointly, up to 300,000 Option Shares from the Company at the same price per
share as the Underwriters shall pay for the Firm Shares. The Option may be
exercised only to cover over-allotments in the sale of the Firm Shares by the
Underwriters and may be exercised in whole or in part at any time (but not more
than once) on or before the 45th day after the date of this Agreement (or, if
the Company has elected to rely on Rule 430A, on or before the 45th day after
the date of the Price Determination Agreement), upon written or telegraphic
notice (the "Option Shares Notice") by the Representatives to the Company no
later than 12:00 noon, New York City time, at least two and no more than five
business days before the date specified for closing in the Option Shares Notice
(the "Option Closing Date") setting forth the aggregate number of Option Shares
to be purchased and the time and date for such purchase. On the Option Closing
Date, the Company will issue and sell to the Underwriters the number of Option
Shares set forth in the Option Shares Notice, and each Underwriter will purchase
such percentage of the Option Shares as is equal to the percentage of Firm
Shares that such Underwriter is purchasing, as adjusted by the Representatives
in such manner as they deem advisable to avoid fractional shares.

         (c) If the Company has elected to rely on Rule 430A, the initial public
offering price per share for the Firm Shares and the purchase price per share
for the Firm Shares to be paid by the several Underwriters shall be agreed upon
and set forth in the Price Determination Agreement. In the event such price has
not been agreed upon and the Price Determination Agreement has not been executed
by the close of business on the fourteenth business day following the date on
which the Registration Statement becomes effective, this Agreement shall
terminate forthwith, without liability of any party to any other party except
that Section 6 shall remain in effect.

         2. Delivery and Payment. Delivery of the Firm Shares shall be made to
the Representatives for the accounts of the Underwriters against payment of the
purchase price by certified or official bank check payable in New York Clearing
House (next-day) funds to the order of the Company at the office of PaineWebber
Incorporated, 1285 Avenue of the Americas, New York, New York 10019, [credit to
the account of the Company with the Depository Trust Company.] Such payments
shall be made at 10:00 a.m., New York City time, on the third business day after
the date on which the first bona fide offering of the Shares to the public is
made by the Underwriters or at such time on such other date, not later than ten
business days after such date, as may be agreed upon by the Company and the
Representatives (such date is hereinafter referred to as the "Closing Date").

         To the extent the Option is exercised, delivery of the Option Shares
against payment by the Underwriters (in the manner specified above) will take
place at the offices specified above for the Closing Date at the time and date
(which may be the Closing Date) specified in the Option Shares Notice.

         The cost of original issue tax stamps, if any, in connection with the
issuance and delivery of the Firm Shares and Option Shares by the Company to the
respective Underwriters shall be borne by the Company. The Company will pay and
save each Underwriter and any subsequent holder of the Shares harmless from any
and all liabilities with respect to or resulting from any failure or delay in
paying Federal and state stamp and other transfer taxes, if any, which may be
payable or determined to be payable in connection with the original issuance or
sale to such Underwriter of the Firm Shares and Option Shares.

         3. Representations and Warranties of the Company. The Company

qualified to do business and in good standing as a foreign corporation in all
jurisdictions in which the nature of the activities conducted by it or the
character of the assets owned or leased by it makes such licensing or
qualification necessary. All of the outstanding shares of capital stock of the
Subsidiaries have been duly authorized and validly issued and are fully paid and
non-assessable and are owned by the Company free and clear of all liens,
encumbrances and claims whatsoever. Except for the stock of the Subsidiaries and

the Company does not have outstanding, and at the Closing Date will not have
outstanding, any options to purchase, or any rights or warrants to subscribe

commitments to issue or sell, any shares of Common Stock, any shares of capital
stock of any Subsidiary or any such warrants, convertible securities or
obligations.

         (f) The financial statements and schedules included or incorporated by
reference in the Registration Statement or the Prospectus present fairly the

conformity with generally accepted accounting principles and to maintain
accountability for assets; (iii) access to assets is permitted only in
accordance with management's general or specific authorization; and (iv) the

except as set forth in or contemplated by the Registration Statement and the
Prospectus, (i) there has not been and will not have been any change in the

agreement") to which it is a party or by which its property is bound or
affected. To the best knowledge of the Company and each of its Subsidiaries, no
other party under any contract or other agreement to which it is a party is in

this Agreement. This Agreement has been duly authorized, executed and delivered
by the Company and constitutes a valid and binding agreement of the Company and
is enforceable against the Company in accordance with the terms hereof. The
performance of this Agreement and the consummation of the transactions
contemplated hereby and the application of the net proceeds from the offering
and sale of the Shares in the manner set forth in the Prospectus under "Use of
Proceeds" will not result in the creation or imposition of any lien, charge or

                                       -5-
   6
encumbrance upon any of the assets of the Company or any of its Subsidiaries
pursuant to the terms or provisions of, or result in a breach or violation of

other party a right to terminate any of its obligations under, or result in the
acceleration of any obligation under, the certificate of incorporation or
by-laws of the Company or any of its Subsidiaries, any contract or other
agreement to which the Company or any of its Subsidiaries is a party or by which
the Company or any of its Subsidiaries or any of its properties is bound or
affected, or violate or conflict with any judgment, ruling, decree, order,

Company or its Subsidiaries. The Company and each of its Subsidiaries has valid,
subsisting and enforceable leases for the properties described in the Prospectus

interfere with the use made and proposed to be made of such properties by the
Company and such Subsidiaries.

         (o) There is no document or contract of a character required to be
described in the Registration Statement or the Prospectus or to be filed as an
exhibit to the Registration Statement which is not described or filed as
required. All such contracts to which the Company or any Subsidiary is a party

Subsidiary, constitute valid and binding agreements of the Company or such
Subsidiary and are enforceable against the Company or such Subsidiary in
accordance with the terms thereof.

         (p) No statement, representation, warranty or covenant made by the
Company in this Agreement or made in any certificate or document required by
this Agreement to be delivered to the Representatives was or will be, when made,
inaccurate, untrue or incorrect.

         (q) Neither the Company nor any of its directors, officers or
controlling persons has taken, directly or indirectly, any action intended, or
which might reasonably be expected, to cause or result, under the Act or
otherwise, in, or which has constituted, stabilization or manipulation of the

issued thereunder with respect to the offering and sale of the Shares.

         4. Agreements of the Company. The Company agrees with the several
Underwriters as follows:

         (a) The Company will not, either prior to the Effective Date or
thereafter during such period as the Prospectus is required by law to be
delivered in connection with sales of the Shares by an Underwriter or dealer,
file any amendment or supplement to the Registration Statement or the
Prospectus, unless a copy thereof shall first have been submitted to the
Representatives within a reasonable period of time prior to the filing thereof
and the Representatives shall not have objected thereto in good faith.

         (b) The Company will use its best efforts to cause the Registration
Statement to become effective, and will notify the Representatives promptly, and
will confirm such advice in writing, (1) when the Registration Statement has
become effective and when any post-effective amendment thereto becomes
effective, (2) of any request by the Commission for amendments or supplements to
the Registration Statement or the Prospectus or for additional information, (3)
of the issuance by the Commission of any stop order suspending the effectiveness
of the Registration Statement or the initiation of any proceedings for that
purpose or the threat thereof, (4) of the happening of any event during the
period mentioned in the second sentence of Section 4(e) that in the judgment of
the Company makes any statement made in the Registration Statement or the
Prospectus untrue or that requires the making of any changes in the Registration
Statement or the Prospectus in order to make the statements therein, in light of
the circumstances in which they are made, not misleading and (5) of receipt by
the Company or any representative or attorney of the Company of any other
communication from the Commission relating to the Company, the Registration
Statement, any preliminary prospectus or the Prospectus. If at any time the
Commission shall issue any order suspending the effectiveness of the
Registration Statement, the Company will make every reasonable effort to obtain
the withdrawal of such order at the earliest possible moment. The Company will
use its best efforts to comply with the provisions of and make all requisite
filings with the Commission pursuant to Rule 430A and to notify the
Representatives promptly of all such filings.

         (c) The Company will furnish to the Representatives, without charge,

amendment thereto, including financial statements and schedules, and all
exhibits thereto (including any document filed under the Exchange Act and deemed
to be incorporated by reference into the Prospectus), and will furnish to the
Representatives, without charge, for transmittal to each of the other
Underwriters, a copy of the Registration Statement and any post-effective

amendment or supplement thereto by the several Underwriters and by all dealers
to whom the Shares may be sold, both in connection with the offering or sale of
the Shares and for any period of time thereafter during which the Prospectus is
required by law to be delivered in connection therewith. If during such period
of time any event shall occur which in the judgment of the Company or counsel to
the Underwriters should be set forth in the Prospectus in order to make any
statement therein, in the light of the circumstances under which it was made,
not misleading, or if it is necessary to supplement or amend the Prospectus to
comply with law, the Company will forthwith prepare and duly file with the
Commission an appropriate supplement or amendment thereto, and will deliver to
each of the Underwriters, without charge, such number of copies thereof as the
Representatives may reasonably request. The Company shall not file any document
under the Exchange Act before the termination of the offering of the Shares by
the Underwriters if such document would be deemed to

                                       -7-
   8
be incorporated by reference into the Prospectus which is not approved by the
Representatives after reasonable notice thereof.

         (f) Prior to any public offering of the Shares by the Underwriters, the
Company will cooperate with the Representatives and counsel to the Underwriters
in connection with the registration or qualification of the Shares for offer and
sale under the securities or Blue Sky laws of such jurisdictions as the
Representatives may request; provided, that in no event shall the Company be
obligated to qualify to do business in any jurisdiction where it is not now so
qualified or to take any action which would subject it to general service of
process in any jurisdiction where it is not now so subject.

         (g) During the period of five years commencing on the Effective Date,
the Company will furnish to the Representatives and each other Underwriter who
may so request copies of such financial statements and other periodic and
special reports as the Company may from time to time distribute generally to the
holders of any class of its capital stock, and will furnish to the
Representatives and each other Underwriter who may so request a copy of each
annual or other report it shall be required to file with the Commission.

         (h) The Company will make generally available to holders of its
securities as soon as may be practicable but in no event later than the last day
of the fifteenth full calendar month following the calendar quarter in which the
Effective Date falls, an earnings statement (which need not be audited but shall
be in reasonable detail) for a period of 12 months ended commencing after the
Effective Date, and satisfying the provisions of Section 11(a) of the Act

the Shares and (10) the Accountants.

         (j) If this Agreement shall be terminated by the Company pursuant to
any of the provisions hereof (otherwise than pursuant to Section 8) or if for
any reason the Company shall be unable to perform its obligations hereunder, the
Company will reimburse the several Underwriters for all out-of-pocket expenses
(including the fees, disbursements and other charges of counsel to the
Underwriters) reasonably incurred by them in connection herewith.

         (k) The Company will not at any time, directly or indirectly, take any
action intended, or which might reasonably be expected, to cause or result in,
or which will constitute, stabilization of the price of the shares of Common
Stock to facilitate the sale or resale of any of the Shares.

         (l) The Company will apply the net proceeds from the offering and sale
of the Shares to be sold by the Company in the manner set forth in the
Prospectus under "Use of Proceeds."

days after the commencement of the public offering of the Shares, without the
prior written consent of PaineWebber Incorporated, sell, contract to sell or
otherwise dispose of any shares of Common Stock or rights to acquire such shares
(other than pursuant to employee stock option plans or in connection with other
employee incentive compensation arrangements).

         (k) The Shares shall be qualified for sale in such states as the

representations and warranties of the Company herein, as to the performance by
the Company of its obligations hereunder, or as to the fulfillment of the
conditions concurrent and precedent to the obligations hereunder of the
Representatives.

         6.       Indemnification.

         (a) The Company will indemnify and hold harmless each Underwriter, the
directors, officers, employees and agents of each Underwriter and each person,
if any, who controls each Underwriter within the meaning of Section 15 of the
Act or Section 20 of the Exchange Act, from and against any and all losses,
claims, liabilities, expenses and damages (including any and all investigative,
legal and other expenses reasonably incurred in connection with, and any amount
paid in settlement of, any action, suit or proceeding between any of the
indemnified parties and any indemnifying parties or between any indemnified
party and any third party, or otherwise, or any claim asserted), to which they,
or any of them, may become subject under the Act, the Exchange Act or other
Federal or state statutory law or regulation, at common law or otherwise,
insofar as such losses, claims, liabilities, expenses or damages arise out of or
are based on any untrue statement or alleged untrue statement of a material fact
contained in any preliminary prospectus, the Registration Statement or the
Prospectus or any amendment or supplement to the Registration Statement or the
Prospectus or in any documents filed under the Exchange Act and deemed to be
incorporated by reference into the Prospectus, or the omission or alleged
omission to state in such document a material fact required to be stated in it
or necessary to make the statements in it not misleading, provided that the
Company will not be liable to the extent that such loss, claim, liability,
expense or damage arises from the sale of the Shares in the public offering to
any person by an Underwriter and is based on an untrue statement or omission or
alleged untrue statement or omission made in reliance on and in conformity with
information relating to any Underwriter furnished in writing to the Company by
the Representatives on behalf of any Underwriter expressly for inclusion in the
Registration Statement, any preliminary prospectus or the Prospectus. This
indemnity agreement will be in addition to any liability that the Company might
otherwise have.

         (b) Each Underwriter will indemnify and hold harmless the Company, each
person, if any, who controls the Company within the meaning of Section 15 of the
Act or Section 20 of the Exchange Act, each director of the Company and each
officer of the Company who signs the Registration Statement to the same extent
as the foregoing indemnity from the Company to each Underwriter, but only
insofar as losses, claims, liabilities, expenses or damages arise out of or are
based on any untrue statement or omission or alleged untrue statement or
omission made in reliance on and in conformity with information relating to any
Underwriter furnished in writing to the Company by the Representatives on behalf
of such Underwriter expressly for use in the Registration Statement, the
Preliminary Prospectus or the Prospectus. This indemnity will be in addition to
any liability that each Underwriter might otherwise have.

         (c) Any party that proposes to assert the right to be indemnified under
this Section 6 will, promptly after receipt of notice of commencement of any
action against such party in respect of which a claim

                                      -11-

   12
is to be made against an indemnifying party or parties under this Section 6,
notify each such indemnifying party of the commencement of such action,
enclosing a copy of all papers served, but the omission so to notify such
indemnifying party will not relieve it from any liability that it may have to
any indemnified party under the foregoing provisions of this Section 6 unless,
and only to the extent that, such omission results in the forfeiture of
substantive rights or defenses by the indemnifying party. If any such action is
brought against any indemnified party and it notifies the indemnifying party of
its commencement, the indemnifying party will be entitled to participate in and,
to the extent that it elects by delivering written notice to the indemnified
party promptly after receiving notice of the commencement of the action from the
indemnified party, jointly with any other indemnifying party similarly notified,
to assume the defense of the action, with counsel satisfactory to the
indemnified party, and after notice from the indemnifying party to the
indemnified party of its election to assume the defense, the indemnifying party
will not be liable to the indemnified party for any legal or other expenses
except as provided below and except for the reasonable costs of investigation
subsequently incurred by the indemnified party in connection with the defense.
The indemnified party will have the right to employ its own counsel in any such
action, but the fees, expenses and other charges of such counsel will be at the
expense of such indemnified party unless (1) the employment of counsel by the
indemnified party has been authorized in writing by the indemnifying party, (2)
the indemnified party has reasonably concluded (based on advice of counsel) that
there may be legal defenses available to it or other indemnified parties that
are different from or in addition to those available to the indemnifying party,
(3) a conflict or potential conflict exists (based on advice of counsel to the
indemnified party) between the indemnified party and the indemnifying party (in
which case the indemnifying party will not have the right to direct the defense
of such action on behalf of the indemnified party) or (4) the indemnifying party
has not in fact employed counsel to assume the defense of such action within a
reasonable time after receiving notice of the commencement of the action, in
each of which cases the reasonable fees, disbursements and other charges of
counsel will be at the expense of the indemnifying party or parties. It is
understood that the indemnifying party or parties shall not, in connection with
any proceeding or related proceedings in the same jurisdiction, be liable for
the reasonable fees, disbursements and other charges of more than one separate
firm admitted to practice in such jurisdiction at any one time for all such
indemnified party or parties. All such fees, disbursements and other charges
will be reimbursed by the indemnifying party promptly as they are incurred. An
indemnifying party will not be liable for any settlement of any action or claim
effected without its written consent (which consent will not be unreasonably
withheld). No indemnifying party shall, without the prior written consent of
each indemnified party, settle or compromise or consent to the entry of any
judgment in any pending or threatened claim, action or proceeding relating to
the matters contemplated by this Section 6 (whether or not any indemnified party
is a party thereto), unless such settlement, compromise or consent includes an
unconditional release of each indemnified party from all liability arising or
that may arise out of such claim, action or proceeding.

         (d) In order to provide for just and equitable contribution in
circumstances in which the indemnification provided for in the foregoing
paragraphs of this Section 6 is applicable in accordance with its terms but for
any reason is held to be unavailable from the Company or the Underwriters, the
Company and the Underwriters will contribute to the total losses, claims,
liabilities, expenses and damages (including any investigative, legal and other
expenses reasonably incurred in connection with, and any amount paid in
settlement of, any action, suit or proceeding or any claim asserted, but after
deducting any contribution received by the Company from persons other than the
Underwriters, such as persons who control the Company within the meaning of the
Act, officers of the Company who signed the Registration Statement and directors
of the Company, who also may be liable for contribution) to which the Company
and any one or more of the Underwriters may be subject in such proportion as
shall be appropriate to reflect the relative benefits received by the Company on
the one hand and the Underwriters on the other. The relative benefits received
by the Company on the one hand and the Underwriters on the other shall be deemed
to be in the same proportion as the total net proceeds from the offering (before
deducting expenses) received by the Company bear to the total underwriting
discounts and commissions received by the Underwriters, in each case as set
forth in the table on the cover page of the Prospectus. If, but only if, the
allocation provided by the foregoing sentence is not permitted by applicable
law, the allocation of contribution shall be made in such proportion as is
appropriate to reflect not only the relative benefits referred to in the
foregoing sentence but also the relative fault of the Company, on the one hand,
and the Underwriters, on the other, with respect to the statements or omissions
which resulted in such loss, claim, liability, expense or damage, or action in
respect thereof, as well as any

                                      -12-
   13
other relevant equitable considerations with respect to such offering. Such
relative fault shall be determined by reference to whether the untrue or alleged
untrue statement of a material fact or omission or alleged omission to state a
material fact relates to information supplied by the Company or the
Representatives on behalf of the Underwriters, the intent of the parties and
their relative knowledge, access to information and opportunity to correct or
prevent such statement or omission. The Company and the Underwriters agree that
it would not be just and equitable if contributions pursuant to this Section
6(d) were to be determined by pro rata allocation (even if the Underwriters were
treated as one entity for such purpose) or by any other method of allocation
which does not take into account the equitable considerations referred to
herein. The amount paid or payable by an indemnified party as a result of the
loss, claim, liability, expense or damage, or action in respect thereof,
referred to above in this Section 6(d) shall be deemed to include, for purpose
of this Section 6(d), any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating or defending any such action
or claim. Notwithstanding the provisions of this Section 6(d), no Underwriter
shall be required to contribute any amount in excess of the underwriting
discounts received by it and no person found guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) will be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation. The Underwriters' obligations to contribute as provided in
this Section 6(d) are several in proportion to their respective underwriting
obligations and not joint. For purposes of this Section 6(d), any person who
controls a party to this Agreement within the meaning of the Act will have the
same rights to contribution as that party, and each officer of the Company who
signed the Registration Statement will have the same rights to contribution as
the Company, subject in each case to the provisions hereof. Any party entitled
to contribution, promptly after receipt of notice of commencement of any action
against such party in respect of which a claim for contribution may be made
under this Section 6(d), will notify any such party or parties from whom
contribution may be sought, but the omission so to notify will not relieve the
party or parties from whom contribution may be sought from any other obligation
it or they may have under this Section 6(d). No party will be liable for
contribution with respect to any action or claim settled without its written
consent (which consent will not be unreasonably withheld).

         (e) The indemnity and contribution agreements contained in this Section
6 and the representations and warranties of the Company contained in this
Agreement shall remain operative and in full force and effect regardless of (i)
any investigation made by or on behalf of the Underwriters, (ii) acceptance of
the Shares and payment therefor or (iii) any termination of this Agreement.

         7. Termination. The obligations of the several Underwriters
under this Agreement may be terminated at any time on or prior to the Closing
Date (or, with respect to the Option Shares, on or prior to the Option Closing
Date), by notice to the Company from the Representatives, without liability on
the part of any Underwriter to the Company, if, prior to delivery and payment
for the Shares (or the Option Shares, as the case may be), in the sole judgment
of the Representatives, (i) trading in any of the equity securities of the
Company shall have been suspended by the Commission, by an exchange that lists
the Shares or by the NASDAQ National Market, (ii) trading in securities
generally on the New York Stock Exchange shall have been suspended or limited or
minimum or maximum prices shall have been generally established on such
exchange, or additional material governmental restrictions, not in force on the
date of this Agreement, shall have been imposed upon trading in securities
generally by such exchange or by order of the Commission or any court or other
governmental authority, (iii) a general banking moratorium shall have been
declared by either Federal or New York State authorities or (iv) any material
adverse change in the financial or securities markets in the United States or in
political, financial or economic conditions in the United States or any outbreak
or material escalation of hostilities or declaration by the United States of a
national emergency or war or other calamity or crisis shall have occurred the
effect of any of which is such as to make it, in the sole judgment of the
Representatives, impracticable or inadvisable to market the Shares on the terms
and in the manner contemplated by the Prospectus.

         8. Substitution of Underwriters. If any one or more of the
Underwriters shall fail or refuse to purchase any of the Firm Shares which it or
they have agreed to purchase hereunder, and the aggregate number of Firm Shares
which such defaulting Underwriter or Underwriters agreed but failed or refused
to purchase is not more than one-tenth of the aggregate number of Firm Shares,
the other Underwriters shall be obligated,

                                      -13-
   14
severally, to purchase the Firm Shares which such defaulting Underwriter or
Underwriters agreed but failed or refused to purchase, in the proportions which
the number of Firm Shares which they have respectively agreed to purchase
pursuant to Section 1 bears to the aggregate number of Firm Shares which all
such non-defaulting Underwriters have so agreed to purchase, or in such other
proportions as the Representatives may specify; provided that in no event shall
the maximum number of Firm Shares which any Underwriter has become obligated to
purchase pursuant to Section 1 be increased pursuant to this Section 8 by more
than one-ninth of the number of Firm Shares agreed to be purchased by such
Underwriter without the prior written consent of such Underwriter. If any
Underwriter or Underwriters shall fail or refuse to purchase any Firm Shares and
the aggregate number of Firm Shares which such defaulting Underwriter or
Underwriters agreed but failed or refused to purchase exceeds one-tenth of the
aggregate number of the Firm Shares and arrangements satisfactory to the
Representatives and the Company for the purchase of such Firm Shares are not
made within 48 hours after such default, this Agreement will terminate without
liability on the part of any non-defaulting Underwriter or the Company for the
purchase or sale of any Shares under this Agreement. In any such case either the
Representatives or the Company shall have the right to postpone the Closing
Date, but in no event for longer than seven days, in order that the required
changes, if any, in the Registration Statement and in the Prospectus or in any
other documents or arrangements may be effected. Any action taken pursuant to
this Section 8 shall not relieve any defaulting Underwriter from liability in
respect of any default of such Underwriter under this Agreement.

         9. Miscellaneous. Notice given pursuant to any of the provisions of
this Agreement shall be in writing and, unless otherwise specified, shall be
mailed or delivered (a) if to the Company, at the office of the Company, 545
Middlefield Road, Suite 200, Menlo Park, California 94025, Attention: Leland F.
Wilson, or (b) if to the Underwriters, to the Representatives at the offices of
PaineWebber Incorporated, 1285 Avenue of the Americas, New York, New York 10019,
Attention: Corporate Finance Department. Any such notice shall be effective only
upon receipt. Any notice under Section 7 or 8 may be made by telex or telephone,
but if so made shall be subsequently confirmed in writing.

         This Agreement has been and is made solely for the benefit of the
several Underwriters and the Company and of the controlling persons, directors
and officers referred to in Section 6, and their respective successors and
assigns, and no other person shall acquire or have any right under or by virtue
of this Agreement. The term "successors and assigns" as used in this Agreement
shall not include a purchaser, as such purchaser, of Shares from any of the
several Underwriters.

         All representations, warranties and agreements of the Company contained
herein or in certificates or other instruments delivered pursuant hereto, shall
remain operative and in full force and effect regardless of any investigation
made by or on behalf of any Underwriter or any of its controlling persons and
shall survive delivery of and payment for the Shares hereunder.

         Any action required or permitted to be taken by the Representatives
under this Agreement may be taken by them jointly or by PaineWebber
Incorporated.

         THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH
THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO THE CONFLICT OF LAWS
PRINCIPLES OF SUCH STATE.

         This Agreement may be signed in two or more counterparts with the same
effect as if the signatures thereto and hereto were upon the same instrument.

         In case any provision in this Agreement shall be invalid, illegal or
unenforceable, the validity, legality and enforceability of the remaining
provisions shall not in any way be affected or impaired thereby.

         The Company and the Underwriters each hereby irrevocably waive any
right they may have to a trial by jury in respect of any claim based upon or
arising out of this Agreement or the transactions contemplated hereby.

                                      -14-
   15
         This Agreement may not be amended or otherwise modified or any
provision hereof waived except by an instrument in writing signed by the
Representatives and the Company.

         Please confirm that the foregoing correctly sets forth the agreement
among the Company and the several Underwriters.

                                                     Very truly yours,

Very truly yours, By:________________________ Print Name:________________ B-1 20 EXHIBIT C Form of Opinion of Counsel to the Company The Company and each of its Subsidiaries is a corporation duly organized, validly existing and in good standing under the laws of the jurisdiction of its incorporation and has full corporate power and authority to conduct all the activities conducted by it, to own or lease all the assets owned or leased by it and to conduct its business as described in the Registration Statement and the Prospectus. The Company is the sole record owner and, to our knowledge, the sole beneficial owner of all of the capital stock of each of its Subsidiaries. All of the outstanding shares of Common Stock have been, and the Shares, when paid for by the Underwriters in accordance with the terms of the Agreement, will be, duly authorized, validly issued, fully paid and nonassessable and will not be subject to any preemptive or similar right under (i) the statutes, judicial and administrative decisions, and the rules and regulations of the governmental agencies of the State of Delaware, (ii) the Company's certificate of incorporation or by-laws or (iii) any instrument, document, contract or other agreement referred to in the Registration Statement or any instrument, document, contract or agreement filed as an exhibit to, or incorporated as an exhibit by reference in, the Registration Statement. Except as described in the Registration Statement or the Prospectus, to the best of our knowledge, there is no commitment or arrangement to issue, and there are no outstanding options, warrants or other rights calling for the issuance of, any share of capital stock of the Company or any Subsidiary to any person or any security or other instrument that by its terms is convertible into, exercisable for or exchangeable for capital stock of the Company. No consent, approval, authorization or order of, or any filing or declaration with, any court or governmental agency or body is required in connection with the authorization, issuance, transfer, sale or delivery of the Shares by the Company, in connection with the execution, delivery and performance of the Agreement including the Price Determination Agreement by the Company or in connection with the taking by the Company of any action contemplated thereby or, if so required, all such consents, approvals, authorizations and orders, have been obtained and are in full force and effect, except such as have been obtained under the Act and the Rules and Regulations and such as may be required under state securities or "Blue Sky" laws or by the by-laws and rules of the NASD in connection with the purchase and distribution by the Underwriters of the Shares to be sold by the Company. All references in this opinion to the Agreement shall include the Price Determination Agreement. The authorized, issued and outstanding capital stock of the Company is as set forth in the Registration Statement and the Prospectus under the caption "Capitalization." The description of the Common Stock contained in the Prospectus is complete and accurate in all material respects. The form of certificate used to evidence the Common Stock is in due and proper form and complies with all applicable statutory requirements. The Registration Statement and the Prospectus (including any documents incorporated by reference into the Prospectus, at the time they were filed) comply in all material respects as to form with the requirements of the Act, the Exchange Act, the Exchange Act Rules and Regulations and the Rules and Regulations (except that we express no opinion as to financial statements, schedules and other financial data contained in the Registration Statement or the Prospectus or incorporated by reference therein). To the best of our knowledge, any instrument, document, lease, license, contract or other agreement (collectively, "Documents") required to be described or referred to in the Registration Statement or the Prospectus has been properly described or referred to therein and any Document required to be filed as an exhibit to the Registration Statement has been filed as an exhibit thereto or has been incorporated as an exhibit by reference in the Registration Statement; and no default exists in the due performance or observance of any material obligation, agreement, covenant or condition contained in any Document filed or required to be filed as an exhibit to the Registration Statement. C-1 21 To the best of our knowledge, except as disclosed in the Registration Statement or the Prospectus, no person or entity has the right to require the registration under the Act of shares of Common Stock or other securities of the Company by reason of the filing or effectiveness of the Registration Statement. To the best of our knowledge, the Company is not in violation of, or in default with respect to, any law, rule, regulation, order, judgment or decree, except as may be described in the Prospectus or such as in the aggregate do not now have and will not in the future have a material adverse effect upon the operations, business or assets of the Company and the Subsidiaries, taken as a whole. All descriptions in the Prospectus of statutes, regulations or legal or governmental proceedings are accurate and fairly present the information required to be shown. The Company has full corporate power and authority to enter into the Agreement, and the Agreement has been duly authorized, executed and delivered by the Company, is a valid and binding agreement of the Company and, except for the indemnification and contribution provisions thereof, as to which we express no opinion, is enforceable against the Company in accordance with the terms thereof. The execution and delivery by the Company of, and the performance by the Company of its agreements in, the Agreement do not and will not (i) violate the certificate of incorporation or by-laws of the Company, (ii) breach or result in a default under, cause the time for performance of any obligation to be accelerated under, or result in the creation or imposition of any lien, charge or encumbrance upon any of the assets of the Company or any of its Subsidiaries pursuant to the terms of, (x) any indenture, mortgage, deed of trust, loan agreement, bond, debenture, note agreement, capital lease or other evidence of indebtedness of which we have knowledge, (y) any voting trust arrangement or any contract or other agreement to which the Company is a party that restricts the ability of the Company to issue securities and of which we have knowledge or (z) any Document filed as an exhibit to, or incorporated as an exhibit by reference in, the Registration Statement, (iii) breach or otherwise violate any existing obligation of the Company under any court or administrative order, judgment or decree of which we have knowledge or (iv) violate applicable provisions of any statute or regulation in the States of Delaware, _________, or of the United States. Delivery of certificates for the Shares will transfer valid and marketable title thereto to each Underwriter that has purchased such Shares in good faith and without notice of any adverse claim with respect thereto. The Company is not an "investment company" or an "affiliated person" of, or "promoter" or "principal underwriter" for, an "investment company," as such terms are defined in the Investment Company Act of 1940, as amended. The Shares have been duly authorized for listing by the NASDAQ National Market upon official notice of issuance. We hereby confirm to you that we have been advised by the Commission that the Registration Statement has become effective under the Act and that no order suspending the effectiveness of the Registration Statement has been issued and no proceeding for that purpose has been instituted or is pending, threatened or contemplated. We hereby further confirm to you that there are no actions, suits, proceedings or investigations pending or, to our knowledge, overtly threatened in writing against the Company or any of its Subsidiaries, or any of their respective officers or directors in their capacities as such, before or by any court, governmental agency or arbitrator which (i) seek to challenge the legality or enforceability of the Agreement, (ii) seek to challenge the legality or enforceability of any of the Documents filed, or required to be filed, as exhibits to the Registration Statement, (iii) seek damages or other remedies with respect to any of the Documents filed, or required to be filed, as exhibits to the Registration Statement, (iv) except as set forth in or contemplated by the Registration Statement and the Prospectus, seek money damages in excess of $50,000 or seek to impose C-2 22 criminal penalties upon the Company, any of its Subsidiaries or any of their respective officers or directors in their capacities as such and of which we have knowledge or (v) seek to enjoin any of the business activities of the Company or any of its Subsidiaries or the transactions described in the Prospectus and of which we have knowledge. We have participated in the preparation of the Registration Statement and the Prospectus and, without assuming any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement or the Prospectus or in any amendment or supplement thereto or in any document incorporated by reference into the Prospectus, nothing has come to our attention that causes us to believe that, both as of the Effective Date and as of the Closing Date and the Option Closing Date, the Registration Statement or any amendment thereto contained or contains any untrue statement of a material fact or omitted or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading or that any Prospectus or any amendment or supplement thereto including any documents incorporated by reference into the Prospectus, at the time such Prospectus was issued, at the time any such amended or supplemented Prospectus was issued, at the Closing Date and the Option Closing Date, contained or contains any untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances in which they were made, not misleading (except that we express no opinion as to financial statements, schedules and other financial data contained in the Registration Statement or the Prospectus or incorporated by reference therein). The foregoing opinion is subject to the qualification that the enforceability of the Agreement may be: (i) subject to bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors' rights generally; and (ii) subject to general principles of equity (regardless of whether such enforceability is considered in a proceeding at law or in equity) including principles of commercial reasonableness or conscionability and an implied covenant of good faith and fair dealing. This letter is furnished by us solely for your benefit in connection with the transactions referred to in the Agreement and may not be circulated to, or relied upon by, any other person, except that this letter may be relied upon by your counsel in connection with the opinion letter to be delivered to you pursuant to Section 5(g) of the Agreement. In rendering the foregoing opinion, counsel may rely, to the extent they deem such reliance proper, on the opinions (in form and substance reasonably satisfactory to Underwriters' counsel) of other counsel reasonably acceptable to Underwriters' counsel as to matters governed by the laws of jurisdictions other than the United States and the State of Delaware, and as to matters of fact, upon certificates of officers of the Company, the Selling Shareholders and of government officials; provided that such counsel shall state that the opinion of any other counsel is in form satisfactory to such counsel. Copies of all such opinions and certificates shall be furnished to counsel to the Underwriters on the Closing Date. C-3

         Re:      Registration Statement on Form S-3

Ladies and Gentlemen:

         We have examined the Registration Statement on Form S-3 to be filed
with the Securities and Exchange Commission (the "Registration Statement"), in
connection with the registration under the Securities Act of 1933, as amended,
of 2,300,000 shares (including an over-allotment option granted to the
underwriter to purchase 300,000 shares) of your Common Stock (the "Shares"), all
of which are authorized. The Shares are to be sold to the underwriter for resale
to the public as described in the Registration Statement and pursuant to the
Underwriting Agreement being filed as an exhibit thereto. As your counsel, we
have examined the proceedings proposed to be taken in connection with the sale
and issuance of the Shares.

         It is our opinion that, upon completion of the proceedings being taken
or contemplated by us, as your counsel, to be taken prior to the issuance of the
Shares, and upon completion of the proceedings being taken in order to permit
such transactions to be carried out in accordance with the securities laws of
the various states, where required, the Shares, when issued and sold in the
manner referred to in the Registration Statement, will be legally and validly
issued, fully paid and nonassessable.

         We consent to the use of this opinion as an exhibit to the Registration
Statement, and further consent to the use of our name wherever appearing in the
Registration Statement, including the Prospectus constituting a part thereof,
and any amendment thereto.

                                             Very truly yours,

                                              WILSON, SONSINI, GOODRICH & ROSATI
