The Company has five operating units: (1) Agrigenetics, Inc., a majority-owned subsidiary doing business as Mycogen Plant Sciences ("Mycogen Plant Sciences" or "MPS"), that produces and markets planting seeds for agricultural and oilseed crops and uses biotechnology and traditional plant breeding techniques to develop pest- resistant and other value-added crop varieties; (2) a biopesticide division that develops, manufactures and markets microbial and fatty acid based biopesticide products; (3) Parasitix Corporation, a wholly owned animal health subsidiary that develops and markets pesticides for use in poultry and livestock operations; (4) an international division that markets internationally the Company's biopesticides and value-added crop varieties through several foreign subsidiaries and distribution networks present in over 50 countries; and (5) Soilserv, Inc., a wholly-owned customized crop protection services subsidiary. The Company's strategy is to use its proprietary Bacillus thuringiensis ("Bt") biotoxin gene technology (i) to expand its portfolio of biopesticide products and (ii) in combination with the plant transformation and other advanced plan science technology of its Mycogen Plant Sciences subsidiary, to develop pest-resistant crop varieties with improved food and fiber characteristics. With a total of 138 U.S. patents, more than 200 foreign patents and approximately 97 additional patent applications pending in the U.S., with corresponding applications pending in other countries, the Company believes that it has a strong proprietary position for its Bt and plant science technology. The Company also will continue to use traditional plant breeding techniques to obtain pest resistance and other value added characteristics from native plant sources, and to breed such characteristics into the Company's elite plant parent lines for its seed crops. Value-added planting seed products incorporating crop protection characteristics into the seed will be commercialized through Mycogen Plant Sciences. The primary focus of this effort will be in corn and cotton, two of the largest crops in terms of seed and pesticide sales. Biopesticides products embodying Mucogen's core technology are sold to the agricultural crop protection markets through the biopesticide division and will be sold to the poultry and livestock markets through the Parasitix subsidiary. The international division will coordinate marketing, sales and distribution of all products outside of North America. Mycogen intends to continue to broaden its participation in the crop protection industry by continuing to refine and apply its technology to better meet the needs of the market and by pursuing strategic transactions and acquisitions. Mycogen was incorporated in California in December 1982 and was reincorporated in Delaware in November 1986. The Company's headquarters are located at 5501 Oberlin Drive, San Diego, California 92121, and its telephone number is (619) 453-8030. RISK FACTORS The following are among the factors that should be considered carefully in evaluating the Company and its business before purchasing the Common Stock offered by this Prospectus. SEASONALITY OF BUSINESS AND PRODUCT TESTING The Company currently markets its products and services primarily for use in the northern hemisphere, where the growing season generally runs from March until October. The seasonal nature of the growing season will cause the Company's operating revenues to be concentrated primarily in the first and second calendar quarters and will result in substantial variations in quarter-to-quarter financial results. Commercial introduction of additional products is contingent on, among other factors, completion of field testing and receipt of required regulatory approvals. Unusual weather conditions during field tests or failure to receive regulatory -3- approvals prior to the growing season may delay field tests, or require additional field tests in subsequent growing seasons, with a resulting delay in product tests, development and commercialization. Such delays could result in additional losses from increased operating expenses in the intervening period without significant offsetting revenues. ABSENCE OF PROFITABLE OPERATIONS The Company first achieved profitability on an annual basis in fiscal 1994. There can be no assurance that profitability will continue on a quarterly or annual basis in the future. There also can be no assurance that the Company will experience revenue growth. As of December 31, 1994, the Company had an accumulated deficit of approximately $97,765,000. Funding to date has been provided primarily through public and private sales of equity securities, product sales, revenues from collaborative agreements with corporate partners and interest income. Operating losses may continue to occur as a result of expenses incurred in anticipation of additional product introductions and continued substantial research and development costs. AGRIBUSINESS RISKS In addition to the risks associated with the development, production and marketing of the Company's products, general market risks are present in the agricultural business. Government policies, both in the United States and overseas, year-to-year fluctuations in pest populations and weather conditions in the growing areas are significant factors in determining the volume of planting seeds and biopesticides sold and, therefore, the Company's revenues. Government policies affect, among other things, crop acreage planted, farmers' decisions as to which crops to plant, the export of agricultural crops, the types of pesticides used and commodity prices. Year-to-year fluctuations in pest populations are influenced by weather conditions, the gestation cycles for particular pests and the effectiveness of pesticides, among other factors. Weather conditions affect seed production yields, planting decisions by farmers and commodity prices. There can be no assurance that current or future government policies will not have a material adverse effect on the Company's business. There can be no assurance that year-to-year fluctuations in certain pest populations will not have a material adverse effect on the Company's business. There also can be no assurance that adverse weather conditions will not have a material adverse effect on the Company's business. HIGHLY COMPETITIVE INDUSTRY The Company faces stiff competition. There are many companies, including planting seed companies and chemical companies, that are seeking to develop new products to protect crops from pests and to increase crop yield. Many of these companies have substantially greater financial and technical resources and production and marketing capabilities than the Company. In addition, many of these companies have had significantly greater resources than the Company to obtain regulatory approval and to market new products. Although the crop protection and planting seed industry is already highly competitive, competition may increase further as a result of the potential advances in the commercial applicability of biotechnology and the greater availability of capital for investment in these fields. Accordingly, there can be no assurance that the Company will be able to continue to compete successfully with its existing competitors or will be able to compete successfully with new competitors. GOVERNMENT REGULATION; PRODUCT APPROVAL Many of the crop protection products under development by the Company are considered pesticides, and are subject to rigorous testing and approval processes by the U.S. Environmental Protection Agency ("EPA") and similar regulatory authorities in various states and in other countries. The process of obtaining such approvals can be lengthy and expensive. There can be no assurance that the Company will be able to obtain the necessary approvals for marketing additional crop protection products. For example, while the EPA has in place a registration procedure for biopesticides that is streamlined in comparison to the registration procedure for chemical pesticides, there can be no assurance that all of the Company's products will be eligible for the streamlined procedure or that additional requirements will not be added by the EPA, which could make the procedure more time-consuming and costly. In addition, the regulatory process for crop protection products using genetic engineering and other methods of biotechnology is evolving and additional restrictions on -4- research and product commercialization may result. If the Company is unable to obtain the necessary approvals to market additional crop protection products, such circumstances would have a material adverse effect on the Company. The field testing, production and marketing of genetically engineered planting seeds by the Company are also subject to federal, state, local and foreign government regulation. The United States Department of Agriculture ("USDA") has not exempted from its permit process the commercial production of genetically engineered plants other than one company's variety of tomato. The production and marketing of genetically engineered plants also are subject to review by the U.S. Food and Drug Administration ("FDA") if the plants are intended to be used as a food product. There can be no assurance that the agencies that oversee current or future regulations of genetically engineered planting seeds will allow the Company to produce and market their genetically- engineered planting seeds in a timely manner or under technically or commercially feasible conditions. In addition, regulatory action or private litigation could result in expenses, delays and other problems for the Company's product development programs and the commercialization of its products. In addition, the Company, and particularly its Soilserv subsidiary, is subject to a variety of federal, state and local environmental regulations in connection with the storage, application and disposal of pesticides and the storage of fuel used in operations. Although the Company believes that it is in compliance with all such environmental regulations, failure to comply with present or future regulations could result in substantial expense or the suspension or cessation of material operations, which could have a material adverse effect on the Company. In addition, in the event of a misapplication of pesticides or improper storage or disposal of pesticides or storage of fuels by the Company, the Company or one or more of its subsidiaries could be held liable for any resulting damages and clean up costs, which liability could have a material adverse effect on the Company. The Company also could be held liable for damages and clean up costs that could result from past storage and disposal of pesticides or storage of fuels, which liability could have a material adverse effect on the Company. MARKET ACCEPTANCE The predominant pest control products in use today are chemical pesticides. The Company's products usually require different pest control practices. The rate at which farmers adopt new pest control practices will affect directly the market acceptance of the Company's products. If market acceptance of the Company's products is slower than anticipated, the Company's product sales would be adversely affected, which could result in continuing or increased losses. There can be no assurance that such products will gain public acceptance, regardless of the status of the regulatory approvals. DEPENDENCE ON PATENTS AND PROPRIETARY TECHNOLOGY The Company has developed proprietary information and techniques and has received and applied for patents relating to its technology and products. There can be no assurance that the patents for which the Company has applied will be issued or that any issued patents will provide adequate protection for the Company's products and processes. In the absence of patent protection, the Company may be vulnerable to competitors who attempt to imitate the Company's products and processes with respect to the Company's products. In addition, other companies and inventors may receive patents that contain claims applicable to some of the Company's products. Sale of the Company's products covered by such patents could require licenses that may not be available on acceptable terms. The patent position of biotechnology firms in general is highly uncertain. There can be no assurance as to the degree and range of protection from biotechnology patents or to the Company's ability to pursue its strategy without infringing the patents of others. The Company also relies upon unpatented proprietary and trade secret technology. Although the Company takes precautions to protect its proprietary and trade secret technology, there can be no assurance that others will not independently develop substantially equivalent information and techniques or otherwise gain access to the Company's trade secrets or proprietary information. Certain companies have been issued patents or have obtained proprietary rights necessary or potentially useful to the Company. The scope and validity of patents and other proprietary rights held by others are presently unknown. If such rights are critical to the Company and cannot be obtained on terms favorable to the Company, delays in the development of products could result, and market introductions of products could be inhibited. -5- INFLUENCE OF CORPORATE RELATIONSHIPS The Company has corporate relationships and intends to enter into future corporate relationships to commercialize certain of its products in non- agricultural and foreign markets. Although the Company believes that its corporate partners will be economically motivated to commercialize the products covered by these relationships in a timely and effective manner, the amount and timing of financial and other resources devoted to these activities generally are influenced by the Company's corporate partners. EXCLUSIVE MANUFACTURING AGREEMENT The Company's microbial bioinsecticides are manufactured by Enzyme Bio-Systems, Ltd. ("EB") pursuant to an exclusive manufacturing agreement. The Company believes that EB has sufficient available capacity at its plant to satisfy the Company's needs for the immediate future. However, if EB were unable to manufacture bioinsecticides for the Company, manufacture of such products could be interrupted until alternative sources could be located. Such an interruption would have a short-term adverse effect and could have a long- term adverse effect on the Company's business. The Company intends to implement a new higher yielding production process for certain of its biopesticide products to improve economics. Implementation of this process at EB may require capital investment by the Company and delays may be encountered which could have a material adverse effect on the Company. PRODUCT LIABILITY The Company faces an inherent business risk of exposure to product liability claims in the event that the use of its current or prospective products results in adverse effects. While the Company will continue to attempt to take appropriate precautions, there can be no assurance that it will avoid significant product liability exposure. The Company currently maintains limited product liability insurance for its products. VOLATILITY OF STOCK PRICE The market prices for securities of emerging companies, including Mycogen, have been highly volatile. Announcements of technological innovations for new commercial products by the Company's present or potential competitors, actual or anticipated financial results, developments concerning patents or other proprietary rights, adverse results in the Company's field tests, adverse litigation, adverse legislation, regulatory decisions at any level of government or public concerns regarding biopesticides or biotechnology may have a significant impact on the Company's business and on the market price of the Company's Common Stock. SHARES ELIGIBLE FOR FUTURE SALE Future sales of shares by existing stockholders pursuant to Rule 144 of the Securities Act of 1933, as amended, or through the exercise of outstanding registration rights could have an adverse effect on the price of the Company's Common Stock. SELLING STOCKHOLDER The following table sets forth certain information regarding the Selling Stockholder's beneficial ownership of the Company's Common Stock as of February 28, 1995.

INDEMNIFICATION OF DIRECTORS AND OFFICERS. Section 145 of the Delaware General Corporation law provides for indemnification of a corporation's officers and directors under certain circumstances. Section 145 of the Delaware General Corporation Law also provides that a corporation has the power to purchase and maintain insurance on behalf of its officers and directors against any liability asserted against such person and incurred by him or her in such capacity, or arising out of his or her status as such, whether or not the corporation would have the power to indemnify him or her against such liability under the provisions of Section 145 of the Delaware General Corporation Law. Section 7.7 of the Bylaws of the Company also provides for indemnification of officers and directors, as authorized by Section 145. Section 102(b)(7) of the Delaware General Corporation Law enables a corporation in its certificate of incorporation to limit the personal liability of members of its board of directors for violations of a director's fiduciary duty of care. The Section does not, however, limit the liability of a director for breaching his or her duty of loyalty, failing to act in good faith, engaging in intentional misconduct or knowingly violating a law, or from any transaction in which the director derived an improper personal benefit. The Section also will have no effect on claims arising under the federal securities laws. The Certificate of Incorporation of the Company limits the liability of its directors as authorized by Section 102(b)(7). The stockholders of the Company have approved indemnification agreements with each of its directors. These agreements provide for indemnification against liability incurred in their capacity as directors. ITEM 16.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Company pursuant to the foregoing provisions, Delaware Corporation law, 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 Act and is, therefor, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer, or controlling person of the Registrant in the successful defense of any action, suit, or proceeding) is asserted by such director, officer, or controlling person in connection with the securities being registered hereunder, the Registrant will, unless in the opinion of its counsel the question has been II-2 settled by controlling precedent, submit to a court of appropriate jurisdiction the question of whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue. The undersigned Registrant hereby undertakes that: (1) For purposes of determining any liability under the Act, the information omitted from the form of Prospectus filed as part of this Registration Statement in reliance upon Rule 430A and contained in a form of Prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Act shall be deemed to be part of this Registration Statement as of the time it was declared effective. (2) For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. II-3 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the Company certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of San Diego, State of California, on the 19th day of April, 1995.
