(the "Company" or "Enzo") employing biotechnology, develops, manufactures and markets health care products, and also provides medical diagnostic services to the medical community. The business activities of the Company are performed by one of the Company's three wholly-owned subsidiaries--Enzo Diagnostics, Inc., Enzo Therapeutics, Inc., and Enzo Clinical Labs, Inc. ("Enzo Diagnostics", "Enzo Therapeutics" and "EnzoLabs", respectively). These activities are: (1) diagnostic and research product development, manufacture and marketing through Enzo Diagnostics, (2) therapeutic product research and development through Enzo Therapeutics, and (3) the operation of a clinical reference laboratory through EnzoLabs. For the fiscal year ended July 31, 1994 (fiscal 1994), approximately 23% of the Company's operating revenues was derived from product sales and approximately 77% was derived from clinical reference laboratory services. For the fiscal years ended July 31, 1993 and 1992 (fiscal 1993 and fiscal 1992, respectively), approximately 11% and 10%, respectively, of the Company's operating revenues were derived from clinical reference laboratory services. The Company's principal executive offices are located at 60 Executive Boulevard, Farmingdale, New York 11735, and its telephone number is (516) 755- 5500. RISK FACTORS In evaluating the Company and its business, prospective purchasers of the Shares offered hereby should consider carefully the following factors in evaluating the Company and its operations: LITIGATION WITH CALGENE, INC. In March 1993, the Company filed suit in the United States District Court for the District of Delaware charging patent infringement and acts of unfair competition against Calgene, Inc. and seeking a declaratory judgment of invalidity concerning Calgene, Inc.'s antisense patent. On February 9, 1994 the Company filed a second suit in the United States District Court for the District of Delaware charging Calgene with infringement of a second antisense patent owned by the Company. Calgene has filed a counterclaim in the second Delaware action seeking a declaration that a third patent belonging to the Company is invalid. The two Delaware actions have been consolidated and were tried to the Court in April 1995. The parties are awaiting the Court's decision. In addition, the Company filed suit on March 22, 1994 in the United States District Court for the Western District of Washington against Calgene and the Fred Hutchinson Cancer Research Center, alleging that the defendants had conspired to issue a false and misleading press release regarding a supposed "patent license" from Hutchinson to Calgene, and conspired to subvert the Company's antisense patents by improperly using confidential 7 information to challenge them in the Patent Office. The Complaint further charge that Hutchinson is infringing and inducing Calgene to infringe the Company's antisense patents. There can be no assurance that the Company will be successful in any of the foregoing matters or that Calgene, Inc. and/or Hutchinson will not be successful. However, even if the Company is not successful management does not believe there will be a significant monetary impact. COMPETITION; TECHNOLOGICAL ADVANCES BY OTHERS. Competitors engaged in genetic engineering in the United States and abroad are numerous and include, among others, major pharmaceutical, energy, food and chemical companies, as well as specialized genetic engineering firms. Many of the large corporations which are involved in genetic engineering have substantially greater resources than the Company and have the capability of developing products which compete directly with the Company's products. Genetic engineering has undergone, and is expected to continue to undergo, rapid and significant technological change. New developments in recombinant DNA, monoclonal antibody and other biotechnological processes are expected to continue at a rapid pace in both industry and academia. Although the Company believes that its products will be commercially viable, no assurance can be given that other developments will not render the Company's products uneconomical or obsolete, or that the Company's products can be marketed successfully. SHARES ELIGIBLE FOR FUTURE SALE. Registration statements filed by the Company with the Securities and Exchange Commission had been declared effective with respect to significant amounts of the Company's Common Stock. Sales of Common Stock pursuant to such registration statements may have an adverse effect on the market price of the Common Stock. UNCERTAINTY OF PRODUCT DEVELOPMENT. The products being pursued by the Company are at various stages of development and clinical evaluations and may require further technical development and investment to determine whether commercial application is practicable. There can be no assurance that the Company's efforts will result in products with valuable commercial applications. UNCERTAINTY OF PATENT PROTECTION; PROPRIETARY TECHNOLOGY. The Company has filed applications for United States and foreign patents covering certain aspects of its technology, but there is no assurance that pending patents will issue or as to the degree of protection which any issued patent might afford. The Company also utilizes certain unpatented proprietary technology. There is no assurance that others may not independently develop similar technology. RETENTION OF KEY PERSONNEL. The specialized scientific nature of the Company's business requires the Company to attract and retain personnel with a wide variety of scientific capabilities. To a large extent, the Company's success in developing proprietary technological products has been the result of the effective efforts of the Company's internal scientific staff and its experience and talent. Since its inception an insignificant number of 8 key employees have left the Company. The Company has elected not to pursue the purchase of key man insurance on any of its officers. There can be no assurance, however, that the Company will continue to attract and retain personnel of high scientific caliber. LAWS AND REGULATIONS. In order to manufacture and market therapeutic and diagnostic products, prior clearance of regulatory agencies, in particular the FDA and similar agencies in other countries, must be obtained. The Company has an in-house regulatory department to assist in the preparation and filing of documentation to expedite FDA approvals and patent issuances. The process of obtaining FDA and corresponding foreign approvals is likely to be costly and time consuming, and there can be no assurance that such approvals will be granted. The process of obtaining approvals for noninvasive diagnostic products is significantly less stringent than approvals for therapeutic products. The extent of potentially adverse government regulations which might arise from future legislation or administrative action cannot be predicted. 9 PRO FORMA (UNAUDITED) FINANCIAL INFORMATION The following unaudited pro forma consolidated balance sheet gives effect to (i) the issuance by the Company of an aggregate of 284,928 shares of Common Stock to the Creditors primarily in consideration of an aggregate of $2,853,976 amount of indebtedness owed or owing by the Company to the Creditors and (ii) the exercise in March 1995 of Warrants previously issued to Granmill and Stockton resulting in the receipt by the Company of gross proceeds of $1,012,500 and the issuance of 50,000 shares of the Company's Common Stock to each of Granmill and Stockton. The pro forma consolidated balance sheets assume such issuances occurred as of July 31, 1994 and April 30, 1995, respectively.

USE OF PROCEEDS None of the proceeds from the sale of the shares by the Selling Stockholders will be received by the Company. The proceeds from the March 1995 exercise of the warrants previously exercised by Granmill and Stockton will be used for working capital.

THE OFFERING The Company hereby offers an aggregate of up to 110,000 shares of its Common Stock by Granmill and Stockton upon the exercise of outstanding warrants issued to them by the Company. In August 1993 the Company issued, pursuant to Regulation S of the Act, to each of Granmill and Stockton, 450,000 shares of the Company's Common Stock in consideration received from each party of $3,600,000. In connection with such purchases the Company granted to each of Granmill and Stockton an aggregate of 125,000 warrants to purchase shares of the Company's Common Stock at exercise prices ranging from $8.00 to $12.00. In September 1993 each of Granmill and Stockton exercised a portion of such warrants to purchase 20,000 shares of Common Stock of the Company. In March 1995 each of Granmill and Stockton exercised an additional portion of such warrants to purchase 50,000 shares of the Company's Common Stock. The remaining 55,000 warrants held by each of Granmill and Stockton are exercisable with respect to (i) 25,000 shares at an exercise price of $8.00 per share during the period September 3, 1994 through September 2, 1999; (ii) 22,500 shares at an exercise price of $9.60 per share during the period September 3, 1994 through September 2, 1999; (iii) 5,000 shares at an exercise price of $8.00 per share during the period March 2, 1996 through September 2, 1998; and (iv) 2,500 shares at an exercise price of $9.60 per share during the period March 2, 1996 through September 2, 1998. If all of the outstanding 110,000 warrants are exercised, of which there can be no assurance, the Company will receive gross proceeds of $960,000. SELLING STOCKHOLDERS The following table sets forth certain information, as of the date hereof, with respect to the Shares held by each Selling Stockholder. The Creditors were issued the 284,928 shares of Common Stock being offered by them hereby in May 1995 primarily in exchange for the cancellation of an aggregate of $2,853,976 owed or to be owed by the Company to them. The Company is currently incurring additional indebtedness to certain of the Creditors who continue to render legal services to the Company.

All of the indebtedness owing to the Creditors constituted unsecured obligations of the Company owing in payment of outstanding professional fees. Each of Granmill and Stockton, two European investors, had previously purchased 450,000 shares of Common Stock from the Company in August 1993 for which each paid a purchase price of $3,600,000.
