("Endogen") was incorporated on June 1, 1983 and commenced commercial operations in November 1985. In March 1993, Endogen became a publicly traded company upon the consummation of the merger of Diagnostics Holding Corp. ("Diagnostics") with and into Endogen, with Endogen being the surviving corporation. The shareholders of Diagnostics consisted of all of the former minority shareholders of Leeco Diagnostics, Inc., a company formerly traded on the NASD OTC Bulletin Board(SM). Endogen is a supplier of specialty reagents and immuno-assay test kits to customers involved in biomedical research, the biotechnology industry and pharmaceutical drug discovery. Endogen uses monoclonal antibody and recombinant DNA technology to develop and manufacture products in the field of cytokines and related immune system factors, the chemical messengers which convey signals within the immune system. Endogen offers three major product lines. The first is in vitro immuno-assay test kits, used for the measurement of human cytokines and related cell surface proteins in biological samples. The second is in vitro immuno-assay test kits, used for the measurement of mouse and other species cytokines, an important and growing area of biomedical research. The third is specialty reagents, including monoclonal antibodies and recombinant proteins, which are used by the biomedical research community in the course of basic and applied research projects. Endogen's product lines provide researchers with tools for investigating the basic cellular mechanisms underlying the human immune system and its response to infection, AIDS, cancer and other diseases. Endogen's products are developed through technology in-licensing agreements with leading medical institutions and pharmaceutical companies, followed by in-house product development, validation, manufacturing and quality control. Endogen's products are sold via catalog and direct selling throughout the United States and are distributed in approximately 40 other countries worldwide. Approximately 44% of Endogen's fiscal 1996 sales were exported, and approximately 33% and 32% of sales were exported in Endogen's fiscal 1995 and 1994, respectively. Endogen has sold its products to almost 1,000 organizations and institutions including pharmaceutical and biotechnology firms, hospitals, universities and biomedical research labs worldwide. -4- The Market Biomedical researchers around the world are constantly in search of specialty research products necessary to conduct basic and applied research. This research is conducted in settings that range from university and medical school laboratories to pharmaceutical and biotechnology research and development groups. Biomedical research depends on the availability of new biomedical products of the type developed and marketed by Endogen. The market for biomedical research products includes specialty reagents as well as enzyme immuno-assay ("EIA") test kits. Endogen's specialty reagents are used by customers as part of their general biomedical research. Endogen's EIA test kits streamline the laboratory research process by eliminating the need for customers to independently develop and validate methods for measuring cytokines and related immune system factors in laboratory samples. Cytokines are small, hormone-like, soluble proteins secreted by activated cells of the immune system. Through their activities, cytokines coordinate and orchestrate the proper functioning of the immune system. These proteins typically are present in extremely small quantities in both the bloodstream and the cells by which they are produced. Cytokines are capable of exerting profound effects on the body even when present in concentrations of less than one nanogram per milliliter (a nanogram is one-billionth of a gram). Cytokines, like growth factors, interact with specialized target receptors and stimulate a chain of secondary messengers leading to a biological response. Such biological responses result from changes in both the molecular capabilities and behaviors of cells. For example, cytokines can activate cells to recognize and eliminate harmful bacteria and viruses. In addition, cytokines are instrumental in the body's defense against cancer, AIDS and other life-threatening diseases. Cytokines are the subject of worldwide research efforts. To date, more than 50 molecules have been identified as cytokines; this number is expected to continue growing as research in this field expands. Cytokines have played a role, not only in biomedical research, but in the emergence of the biotechnology industry where gene splicing is used to produce large quantities of a single protein for therapeutic use. Endogen believes that the products it provides to the biomedical research market are well-matched to the growing interest in the cytokine and cytokine-related field. There can be no assurance, however, that this field will continue to expand or that the Company's products will be successfully introduced into the marketplace. See "BUSINESS--Risk Factors" herein. Specialty Research Reagents Endogen currently offers approximately 200 specialty reagent products. These include recombinant DNA-derived cytokines, polyclonal and monoclonal antibodies. Such products are used by customers to investigate the biological responses evoked by immune system proteins. Applications for Endogen's research reagents include a variety of laboratory experiments involving live cell cultures or laboratory animal models. In-licensing agreements for novel hybridoma cell lines which produce monoclonal antibodies provide a significant source of new specialty reagents. Endogen develops and maintains relationships with leading medical research institutions across the United States and overseas through activities, including attendance at scientific meetings. This allows Endogen to identify new products and to support its existing products. There can be no assurance, however, that the Company will maintain these relationships or that these relationships will continue to facilitate the Company's development with respect to new and existing products. -5- In Vitro Assay Kits Endogen currently markets 49 in vitro assay kits. Thirty-two of the kits measure human cytokines and related biomolecules; the other seventeen kits measure mouse, rat, pig and rabbit cytokines and related biomolecules. Most of Endogen's test kits are for laboratory research only, not for diagnostic or therapeutic use. One test kit acquired from T Cell Diagnostics, Inc. ("TCD") measures soluble IL2R which is approved for the diagnosis of hairy cell leukemia. In general, EIA kits are used by customers to precisely determine the level of a particular cytokine in serum, plasma or other biological samples. EIAs provide for more specific, reproducible and easier techniques for measuring biological factors. Prior to the development of EIAs, cytokines and other factors were measured using cell-based bioassays in which the cytokine level in a sample is estimated by observing the experimental sample's effect on cultured live cells, relative to a standard of known effect. In a typical EIA test kit, an antibody specifically isolates the cytokine from a researcher's sample during the first incubation step. A second antibody then binds to the captured cytokine. This second antibody is linked to an enzymatic tag which provides a measurable signal, allowing precise determination of the cytokine concentration in the sample, even in minute concentrations. Results from the assay are recorded using a standard laboratory instrument. Endogen believes that the discovery of new cytokines, coupled with ongoing research on the cellular and molecular role of cytokines in preventing and combating disease, will continue to increase demand for this product line. There is no assurance, however, that any of the reagents or test kits that are presently in the research and development phase can be developed, or if developed, successfully introduced into the marketplace. See "BUSINESS - Risk Factors" herein. Product Licensing Endogen obtains commercial rights to new technologies and new products for the research markets through in-licensing. In-licensing generally provides Endogen with the raw materials for product development in a timely fashion, thereby reducing the product development cycle time and supporting in-house manufacturing capabilities. Endogen's success will depend in part upon its ability to keep pace with evolving technologies and market demands for specialty biological products. Endogen is highly dependent on product licensing arrangements as a source for the basic components utilized in the development and manufacture of both human and mouse product lines. See "BUSINESS - Risk Factors" herein. Through certain in-license agreements, Endogen has obtained cell lines for the production of monoclonal antibodies utilized in the majority of the Company's human and animal test kits. The antibodies are also sold as specialty reagents. These products, manufactured at Endogen, accounted for a substantial portion of revenues for fiscal 1996. Products Under Development Endogen is currently developing additional antibodies, recombinant proteins and test kits for segments of the life sciences market. These programs are expected to result in further expansion of its existing product lines and the introduction of new product lines. Kits for the measurement of novel biomolecules are currently in the prototype stage of development and several of these products are expected to reach the marketplace in fiscal 1997. There is no assurance, however, that any of the specialty reagents or test kit products that are presently in the research and development phase can be -6- developed, or if developed, be successfully introduced into the marketplace. Research and development expenditures totaled $758,772, $956,386 and $1,124,910 in fiscal years 1994, 1995, and 1996, respectively. Purchased in-process research and development expense related to the TCD asset purchase in March 1996 totaled $579,600. See "MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS" herein. Business Relationships Endogen has entered into a number of business relationships with commercial organizations, including the following: Endogen entered into a distribution agreement with Funakoshi Co., Ltd. ("Funakoshi") in 1988. Under the terms of the agreement, subject to certain performance objectives, Endogen grants exclusive rights to Funakoshi to distribute products under the Endogen label in the Japanese market. In 1991, Endogen entered into a distribution and supply agreement with Biozol Diagnostica Vertrieb, GmbH ("Biozol") under which Biozol has exclusively distributed Endogen's products to individual country distributors in certain European countries. Effective September 1, 1996, the agreement has been amended so that Endogen will distribute its products directly to individual country distributors in Europe. Biozol will continue as Endogen's exclusive distributor in Germany. In 1994, Endogen entered into a three-year worldwide product supply and marketing agreement with Amersham International PLC ("Amersham PLC") and initiated distribution of Endogen's mouse cytokine ELISA kits under the Amersham PLC label. In September 1995, the agreement was broadened to include distribution of Endogen's human cytokine ELISA kits under Amersham PLC label. Amersham PLC is a leader in the market for biomedical products such as labeled compounds, antibodies and test kits and is a leading developer and marketer of radiopharmaceuticals and reagents. Endogen continues to manufacture and market human and animal test kit product lines under its own label in addition to supplying Amersham PLC. In 1994, Endogen entered into an investment banking and financial advisory services agreement with Barber and Bronson, Incorporated ("B&B") which, by its terms expired in December 1995. Pursuant to that agreement, Endogen granted a warrant to B&B to purchase up to 180,000 shares of Endogen's common stock. The warrant is exercisable through December 15, 1999 at exercise prices ranging from $2.00 to $4.00 per share. In 1996, Endogen entered into an asset purchase agreement with Cytokine Sciences, Inc. ("CSI"), a manufacturer and seller of cytokine specialty reagents and test kits. Under the terms of the agreement, Endogen acquired two novel product lines in exchange for $100,000 cash and 20,984 shares of Endogen common stock. In 1996, Endogen entered into an agreement with T Cell Sciences, Inc. ("TCS") and T Cell Diagnostics, Inc. ("TCD") pursuant to which Endogen acquired substantially all of the assets and operating business of TCD, TCS's subsidiary, and certain assets of TCS, in exchange for a $2,002,978 convertible subordinated note payable over five years beginning in September 1996, a $452,153 short-term promissory note and $528,341 cash. Endogen now markets all of the research products formerly sold under the TCD name. Endogen also manufactures certain diagnostic products, acquired from TCD, one of which is approved for sale in the U.S. and a second which is supplied under contract to a partner -7- in Japan. Endogen further agreed to manufacture certain diagnostic products for TCS for a period of five years. Government Regulation Most of Endogen's products are marketed as "research use only" products and are not currently regulated by the U.S. Food and Drug Administration (the "FDA"). As a result of the acquisition of TCD's operating business, Endogen now manufactures certain in vitro diagnostic products which are subject to regulation by the FDA. Consequently, the Company's manufacturing facility is regulated by the FDA under Good Manufacturing Practices regulations and is therefore subject to periodic site inspections. Endogen's laboratories and manufacturing operations are subject to regulation by a variety of other federal, state, and local governmental agencies. See "BUSINESS - Risk Factors" herein. Availability of Raw Materials Endogen holds licenses to and maintains back-up stocks of various cell lines that are necessary to the manufacture of key components of its product lines. Endogen believes that it maintains adequate supplies of materials on hand to allow it to continue to manufacture products and meet customer demand. Patents, Trademarks, and Trade Secrets Endogen relies upon trade secrets and proprietary know-how in addition to licensing arrangements to maintain and develop its business. Although Endogen seeks to protect its proprietary information, there can be no assurance that others will not either independently develop the same or similar information, obtain unauthorized access to Endogen's proprietary information or misuse information to which Endogen has granted access. Endogen has obtained federal trademark registration for the Endogen name and mark in the United States. Trademark registration has also been obtained or is pending in various foreign countries. No assurance can be given that Endogen's products do not infringe upon patents or proprietary rights owned or claimed by others. Except as noted below, Endogen has not been notified that its products infringe upon proprietary rights held by others; nor has it conducted patent infringement studies. See "BUSINESS - - Risk Factors" herein. Significant Customers Endogen's largest customers are Amersham PLC, Funakoshi and Biozol. Amersham PLC distributes certain of Endogen's test kits under the Amersham PLC label, pursuant to a three-year worldwide product supply and marketing agreement with Endogen. Sales to Amersham PLC totaled $1,224,000 in fiscal year 1996. Endogen sells its products to Funakoshi for distribution in Japan under the terms of a distribution agreement. Sales under this agreement were approximately $473,000, $429,000 and $657,000 for the fiscal years 1994, 1995 and 1996, respectively. Endogen has sold its -8- products since 1991 to Biozol for European distribution under the terms of their distribution and supply agreement. Sales under this agreement were approximately $393,000, $527,000 and $492,000 for the fiscal years 1994, 1995, and 1996, respectively. Biozol currently owns approximately 5% of the outstanding capital stock of Endogen. See "BUSINESS - Business Relationships" herein. Export Sales Export sales to Europe accounted for approximately 28% of revenues in fiscal 1996 compared with 22% of revenues in fiscal 1995 and 15% in fiscal 1994. The increase in fiscal 1996 was related primarily to the addition of new products sold under the Endogen name and under private label. The increase in fiscal 1995 was primarily due to new product introductions. Export sales to Japan and the Far East accounted for 13%, 8% and 14% of Endogen product revenue for the fiscal years 1996, 1995 and 1994, respectively. Seasonality of Business Endogen's customers include university-based research centers and hospital laboratories whose operations follow the academic calendar. Sales levels worldwide are often lower in the summer months. Accordingly, the first quarter of Endogen's fiscal year, which runs from June through August, tends to be the weakest quarter of Endogen's fiscal year, although Endogen cannot predict if this tendency will continue. Backlog There was no significant backlog for Endogen's products over the past three years. Endogen ships most orders within one week of the placement of the order. Competition The life science market, including research biologicals and Cytokine EIA kits, is supplied by a number of established biomedical products manufacturers located in the United States, Europe and Japan. Many of Endogen's competitors are actively developing additional products for this market. Many of Endogen's competitors have substantially greater financial, research and development, manufacturing, marketing, and human resources than Endogen. Consequently, Endogen expects the continuation of intensive competition in the biomedical products market. See "BUSINESS - Risk Factors" herein. Employees Endogen had 59 full-time and part-time employees as of May 31, 1996. Endogen recognizes that its future success depends in part on its ability to recruit and retain talented and trained scientific and commercial personnel. See "BUSINESS - Risk Factors" herein. Endogen believes that it has been generally successful in hiring and retaining such personnel, but there can be no assurance that such success will continue. None of Endogen's employees is represented by a labor union, and Endogen considers its relations with its employees to be excellent. -9- Risk Factors The Company's future business, operating results and financial condition are subject to various risks and uncertainties, including those described below. Capital Requirements. In the future Endogen may need to raise substantial additional funds through equity or debt financings, research and development financings, collaborative relationships or otherwise. Endogen may seek to raise funds whenever conditions are favorable, even if it does not have an immediate need for additional capital at that time. There can be no assurance that any such additional funding will be available to Endogen or, if available, that it will be on reasonable terms. Any such additional funding may result in significant dilution to existing shareholders. If adequate funds are not available, Endogen may be required to significantly curtail its operations or obtain funds through arrangements with collaborative partners that may require Endogen to relinquish certain material rights to its products. Risks Related to Growth through Acquisition. The Company's strategy is to continue its internal growth and to pursue additional acquisitions of, or relationships with, other companies as strategic opportunities arise in the biomedical industry and related industries. As a result, the Company is subject to certain growth-related risks, including the risk that it will be unable to retain personnel or acquire other resources necessary to adequately accommodate such growth. There can be no assurance that any suitable opportunities for future strategic acquisitions or relationships will arise or, if they do arise, that the transactions contemplated thereby could be completed. There can be no assurance that the Company will be able to integrate effectively into the Company the businesses that the Company has acquired or those that it may acquire in the future. In addition, such transactions are subject to various risks generally associated with the acquisition of businesses, including the financial impact of expenses associated with the integration of businesses and the diversion of management resources. There can be no assurance that any recent or future acquisition or other strategic relationship will not have an adverse impact on the Company's business or results of operations. If suitable opportunities arise in the future, the Company anticipates that it would finance such transactions, as well as its internal growth, through working capital or, in certain instances, through additional debt or equity financing. There can be no assurance, however, that such debt or equity financing would be available to the Company on acceptable terms when, and if, suitable strategic opportunities arise. Uncertainty of Future Profitability. To sustain future profitability Endogen must, among other things, continue to market its current research products and successfully introduce new products to the market. There can be no assurance that Endogen will be able to continue manufacturing its current products, successfully develop new products or that such products, if developed, will be in demand by customers. Endogen expects to incur substantial expenses over the next several years as its product lines and operations expand. There can be no assurance that Endogen will be able to sustain profitability. Dependence on Technology Licensing. Endogen is highly dependent on technology and product licensing arrangements as a principal source for the basic components used in the development and manufacture of its products. Endogen -10- expects to continue to need licenses to proprietary cell lines, patents or other proprietary rights of third parties. No assurance can be given that any licenses required under any such patents or proprietary rights would be made available on terms acceptable to Endogen, if at all. In addition, certain of Endogen's technology and product licenses have been obtained under non-exclusive terms. No assurances can be given that such technologies or products will not be licensed or commercialized by competitors and marketed to the same customers. See "BUSINESS - Product Licensing" herein. Competition and Risk of Technological Obsolescence. Competitors of Endogen in the United States and abroad are numerous and include, among others, biotechnology companies, diagnostics manufacturers and catalog supply companies. Endogen's success depends upon developing and maintaining a competitive position in the development of products and technologies in its area of focus. Competition from other research products and diagnostics companies is intense and expected to increase as new products enter the market and new technologies become available. Endogen's competitors may also succeed in developing technologies and products that are more effective than any which have been or are being developed by Endogen or that render Endogen's technologies or products obsolete or noncompetitive. Endogen's competitors may also succeed in obtaining patent protection or other intellectual property rights that would block Endogen's ability to develop new products. Finally, many of these competitors have substantially greater research and development capabilities, manufacturing, regulatory and marketing experience and financial and managerial resources than Endogen. See "BUSINESS - Competition" herein. Government Regulation. Endogen's research and development programs, as well as its manufacturing and marketing operations, are subject to extensive regulation by numerous governmental authorities in the United States and other countries. Certain of Endogen's products are subject to governmental approval for continued commercial sale. The manufacturing and marketing of additional products in the future for diagnostic use would be subject to the rigorous testing and approval processes of the FDA and corresponding foreign regulatory authorities. Dependence on Proprietary Technology. Endogen's success will depend, in part, on its ability to preserve its trade secrets and operate without infringing the proprietary rights of third parties. Endogen could encounter delays in product market introductions while it attempts to design around such patents or other rights, or be unable to develop, manufacture or sell such products. See "BUSINESS - Patents, Trademarks and Trade Secrets" herein. Endogen also seeks to protect its proprietary technology, including technology which may not be patented or patentable, in part by confidentiality agreements and, if applicable, inventors' rights agreements with its collaborators, advisors, employees and consultants. There can be no assurance that these agreements will not be breached, that Endogen will have adequate remedies for any breach, or that Endogen's trade secrets will not otherwise be disclosed to, or discovered by, competitors. Commercial Sales and Marketing Requirements. Endogen currently sells its research products directly to end-users in the United States and through distributors abroad. While Endogen has expanded its marketing and sales force, there can be no -11- assurance that Endogen will be able to further expand its sales and distribution capabilities for the research market without undue delays or expenditures or that it will be successful in maintaining market acceptance for its products. Dependence Upon Key Personnel. Endogen is highly dependent on the members of its management and scientific staff, the loss of whom could have a material adverse effect on Endogen. Endogen also depends on scientific advisors, who may have commitments that limit their availability to Endogen. In addition, Endogen believes that its future success will depend in large part upon its ability to attract and retain highly skilled scientific, managerial and marketing personnel. Endogen faces significant competition for such personnel from other companies, research and academic institutions, government entities and other organizations. There can be no assurance that Endogen will be successful in hiring or retaining the personnel it requires for continued growth. The failure to hire and retain such personnel could materially and adversely affect Endogen's prospects. See "BUSINESS - Employees" herein. International Operations. The percentage of revenues from international sales were 44%, 33% and 32% in fiscal years 1996, 1995 and 1994, respectively. Endogen believes that international sales will continue to represent a significant portion of its business. Endogen's international business and financial performance may be adversely affected by such matters as fluctuations in exchange rates, tariff regulations and difficulties in obtaining export licenses. In addition, Endogen's business may be adversely affected by lower sales levels that typically occur during the summer months in Europe and other parts of the world. ITEM 2. PROPERTIES. Endogen leases but does not own real property. Endogen's executive offices and manufacturing operations currently occupy approximately 38,000 square feet located at 6-8 Gill Street, Woburn, Massachusetts pursuant to a lease, acquired through the TCD acquisition, which expires in June 2001. Rent payments at this facility totaled approximately $68,000 from March 4, 1996 through May 31, 1996. Annual rent payments for each of the remaining years under the lease will average approximately $229,000, payable in monthly installments. In addition, Endogen pays certain operating expenses and will depreciate approximately $938,000 of existing leasehold improvements over the three-and-one-half years remaining in the initial term of the Gill Street lease. In connection with the acquisition of TCD, Endogen is in the process of consolidating all operations formerly located at 640 Memorial Drive, Cambridge, Massachusetts to Woburn, Massachusetts. On May 31, 1996, Endogen entered into a lease termination agreement with Massachusetts Institute of Technology ("MIT") covering the approximately 21,000 square feet located at 640 Memorial Drive, Cambridge, Massachusetts. Endogen has been released from all commitments under the Cambridge lease and, in addition, will be reimbursed approximately $354,000 by MIT for undepreciated leasehold improvements over a 33-month period. Endogen will continue to occupy approximately 5,000 square feet of laboratory space at the Cambridge, Massachusetts location until September 29, 1996 through a sub-lease from Millennium Pharmaceuticals, Inc. On August 1, 1996, Endogen entered into a three-year lease agreement with Landman Omnibus XI Limited Partnership for approximately 12,000 square feet of office and laboratory space at 30 Commerce Way, Woburn, Massachusetts. Rent will be payable effective December 1, 1996. Payments will total -12- approximately $52,000 for the year ending May 31, 1997 and afterwards will average approximately $103,000 per year, payable in monthly installments. The Company believes its present facilities are adequate to meet current needs. ITEM 3. LEGAL PROCEEDINGS. Endogen is not a party to and none of its property is subject to any material pending legal proceedings. ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS. No matters were submitted to a vote of the security holders during the fourth quarter of the Company's fiscal 1996. PART II ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS. The Company's Common Stock was traded on the NASD OTC Bulletin Board(SM) under the symbol "ENDG" since its initial public offering on March 19, 1993. The Company's Common Stock has been traded on the Nasdaq SmallCap Market since September 18, 1995 under the symbol "ENDG" and on the Boston Stock Exchange under the symbol "EDG" since May 12, 1994. Prior to March 19, 1993, there was no public market for the Company's Common Stock.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS. The following discussion includes forward-looking statements, including, but not limited to, statements with respect to the Company's future financial performance, operating results, plans and objectives, and actual results may differ materially from those currently anticipated depending upon a variety of factors, including those described above. See "BUSINESS - Risk Factors" herein. Results of Operations As an aid to understanding Endogen's operating results, the following table shows each item from the statement of operations expressed as a percentage of revenues. PERCENTAGE OF REVENUES Fiscal year ended May 31, 1994 1995 1996 ----- ---- ---- Revenues 100.0% 100.0% 100.0% Costs and expenses: Cost of sales 31.8% 34.9% 37.3% Selling, general, and administrative 57.3% 46.1% 47.3% Research and development 23.2% 18.9% 17.0% Purchased in-process R&D -- -- 8.8% Income (loss) from operations (12.3%) .1% (10.4%) Interest income (expense) net 1.0% .4% (.2%) Net income (loss) (11.3%) .5% (10.6%) As described below, the primary reason for the net loss of $700,539 or $0.25 per share for the fiscal year ended May 31, 1996 were fiscal fourth quarter charges of $579,600, or $0.20 per share, relating to purchased in-process research and development associated with the acquisition of substantially all of the assets and operating business of T Cell Diagnostics ("TCD") in March 1996 as well as other charges of approximately $384,400, or $0.14 per share, related to the TCD acquisition and integration of the two operations. Revenues Total revenues of Endogen were $6,622,161, $5,072,075, and $3,266,410 in fiscal years 1996, 1995, and 1994, respectively. Total revenues increased by $1,550,086, or 31%, from fiscal 1995 to fiscal 1996 and increased by $1,805,665, or 55%, from fiscal 1994 to fiscal 1995. Revenues from all three years were derived entirely from product sales. Revenues increased primarily because of expanded sales of existing products and the introduction of new products. The consolidation of the TCD product revenues beginning in March 1996 contributed to the growth of revenues for the fiscal fourth quarter and year ended May 31, 1996. Cost of Sales Cost of sales was $2,476,997, $1,772,051, and $1,037,048 for fiscal years 1996, 1995, and 1994, respectively. Cost of sales as a percentage of product revenues increased to 37% in fiscal 1996 from 35% in fiscal 1995, due primarily to the increased inventory valuation, and subsequent charge to cost of goods of the finished goods acquired from TCD under purchase accounting rules and sold during the fiscal fourth quarter. The difference between 35% in fiscal 1995 and 32% in fiscal 1994 was due -16- primarily to the addition of manufacturing staff in order to meet increased customer demand for Endogen products, and also to higher overhead costs associated with the Cambridge manufacturing facility which was occupied in April 1994. Research and Development Expenses Research and development expenses were $1,124,910 for the year ended May 31, 1996, up from $956,386 in fiscal 1995 and $758,772 in fiscal 1994. As a percentage of revenues, research and development expenses were 17% in fiscal 1996, versus 19% in fiscal 1995 and 23% in fiscal 1994. The Company's 1996 spending on R&D, which increased 18% from fiscal 1995 to fiscal 1996 and 26% from fiscal 1994 to fiscal 1995, reflects the continued commitment to invest in the development of new products. However, R&D spending decreased from 19% of revenues in fiscal 1995 to 17% of revenues in fiscal 1996 as a direct result of the growth of Endogen's business. The Company also recognized a charge of $579,600 in the fourth quarter of fiscal 1996 for purchased in-process R&D in connection with the TCD acquisition. The purchased in-process R&D consisted of several early-stage EIA kit development projects. At the date of acquisition the technology underlying such projects was unproven and had no future alternative uses. The valuation of the purchased in-process R&D expense was conducted using discounted cash flow analysis by offsetting the costs of completing the projects against the projected net cash flows which could result upon commercialization. It is estimated that to complete development of the acquired technology into commercially viable products, it would take up to one year and an estimated $425,000. Selling, General and Administrative Expenses Selling, general and administrative expenses were $3,130,629, $2,337,700, and $1,872,499 in fiscal years 1996, 1995, and 1994, respectively. Selling, general and administrative expenses increased by $792,929 from fiscal 1995 to fiscal 1996 as the field sales force, staffing and overhead charges increased. Selling, general and administrative expenses were 47% as a percentage of product revenue for fiscal 1996 versus 46% for fiscal 1995. This increase is due to charges associated with the acquisition and integration of the TCD business into Endogen. Looking at fiscal 1995 versus fiscal 1994, selling, general and administrative expenses decreased to 46% of revenues from 57% due to the substantially higher sales level and administrative cost controls. Interest Income and Interest Expense In fiscal 1996, net interest expense was $10,564 compared to net interest income of $18,364 in fiscal 1995 and $31,820 in fiscal 1994. This is a result of a decrease of cash balances over the past two years due to the expansion of Endogen's business as well as increased borrowing levels related to the acquisition of certain assets from TCD in March 1996. Income Taxes Endogen did not have a provision for income taxes for fiscal years 1996, 1995, or 1994. In fiscal year 1995, Endogen reported net income of $24,302 but had sufficient net operating loss carryforwards to offset taxable income and research and development tax credit carryforwards to reduce tax liabilities. In fiscal years 1996 and 1994, Endogen reported net losses of $700,539 and $370,089, respectively. -17- Inflation and Changing Prices The Company believes that inflation has not had a material effect on its operations or on its financial condition. Foreign Currency Transactions Substantially all of Endogen's revenues generated outside of the United States are negotiated, invoiced and paid in U.S. dollars. Consequently, there have been no gains or losses to date on foreign transactions. New Accounting Standard Statement of Financial Accounting Standards No. 123 ("SFAS No. 123"), "Accounting for Stock-Based Compensation," was issued in October 1995. In fiscal 1997, the Company intends to adopt the pro forma disclosure method outlined in SFAS No. 123 and continue to measure compensation cost under the provisions of APB Opinion No. 25, "Accounting for Stock Issued to Employees." Because the pro forma disclosure method has been selected, the adoption of SFAS No. 123 will not impact the Company's results of operations or financial position. Liquidity and Capital Resources The continued growth of Endogen's business during the year ended May 31, 1996 has increased working capital needs. This included financing inventories which increased by $308,208 and accounts receivable which increased by $602,350 as well as expanded manufacturing capacity in the form of property, plant and equipment. The increased levels of inventory and accounts receivable include amounts assumed in the CSI acquisition and the TCD acquisition. Endogen has financed its liquidity needs primarily with cash in the bank. In addition, Endogen issued a convertible subordinated note in the amount of $2,002,978 in connection with the TCD acquisition. At May 31, 1996, Endogen had utilized $450,000 of a $500,000 working capital line of credit with a bank. Subsequent to year end, the working capital line of credit has been increased to $850,000 with an expiration in August 1997 and a $400,000 term loan for the purchase of fixed assets has been added. At May 31, 1996, Endogen's cash and cash equivalents position was $763,739, a decrease of $540,220 from May 31, 1995. Net cash provided by operations in fiscal 1996 was $732,855, in contrast to $112,463 used in fiscal 1995. However, acquisition of fixed assets in the amount of $346,033, the cash used in the purchase of CSI in the amount of $100,000 and cash utilized in the acquisition of TCD in the amount of $1,230,005 resulted in a total cash use for investing activities of $1,676,038. Further cash was provided through an increase in borrowings of $95,751 and proceeds from the issuance of common stock of $307,212. The Company expects to continue expanding operations through internal growth and strategic acquisitions offering products similar or complementary to those offered by the Company. Although the Company has no material current acquisition agreements or arrangements, there may be opportunities which require additional external financing, and the Company may from time to time seek to obtain additional funds from public or private issuance of equity or debt securities. There can be no assurance that such financing will be available at all or on terms acceptable to the Company. The Company estimates that its working capital, cash flow from operations and available borrowings under credit arrangements will be sufficient to fund the Company's current operations through fiscal 1997. The foregoing statements contain forward-looking statements which involve risks and uncertainties. The Company's actual experience may differ materially from that discussed above. -18- Factors that might cause such a difference include, but are not limited to, those discussed in "BUSINESS - Risk Factors," as well as future events that have the effect of reducing the Company's available cash balances, such as unanticipated operating losses or capital expenditures or cash expenditures related to possible future acquisitions.

(the "Company") is principally engaged in the development, manufacture and sale of biological products and test kits for the medical research industry. The Company was incorporated in Massachusetts in June 1983. 2. Summary of Significant Accounting Policies Cash and Cash Equivalents The Company invests its excess cash in money market accounts with banks. These investments, totalling $1,032,704 and $36,536 at May 31, 1995 and 1996, respectively, mature within three months of the initial investment. Accordingly, the investments are subject to minimal credit and market risk and are considered by the Company to be cash equivalents. In accordance with Statement of Financial Accounting Standards No. 115, "Accounting for Certain Investments in Debt and Equity Securities," the Company has classified its investments as held-to-maturity which have been recorded at amortized cost on the Company's balance sheet, which approximates fair value. Revenue Recognition The Company recognizes revenue upon product shipment. Inventories Inventories are stated at the lower of cost or market, cost being determined using the first-in, first-out method. Fixed Assets Fixed assets are recorded at cost and depreciated using the straight-line method over their estimated useful lives. Repair and maintenance expenditures are charged to expense as incurred. Patent and License Costs Costs associated with patents and licensing arrangements are capitalized as incurred and amortized on a straight-line basis over the estimated economic lives, which range from 5 to 10 years. Advertising Costs Costs associated with sales catalogues are capitalized as incurred and amortized as the catalogues are distributed. Income Taxes The Company utilizes the liability method of accounting for income taxes, as set forth in Statement of Financial Accounting Standards No. 109, "Accounting for Income Taxes". Under this method, deferred tax liabilities and assets are recognized for the expected future tax consequences of temporary differences between the carrying amounts and the tax basis of assets and liabilities. Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. F-7 Endogen, Inc. Notes to Financial Statements - (Continued) Net Income (Loss) Per Share Net income (loss) per share is determined by dividing net income (loss) by the weighted average number of common shares and common share equivalents outstanding during the period. Common share equivalents have been excluded from the computation for periods in which the Company incurred a net loss because their effect would be antidilutive. New Accounting Standard Statement of Financial Accounting Standards No. 123 ("SFAS No. 123"). "Accounting for Stock-Based Compensation," was issued in October 1995. In fiscal 1997, the Company intends to adopt the pro forma disclosure method outlined in SFAS No. 123 and continue to measure compensation cost under the provisions of APB Opinion No. 25, "Accounting for Stock Issued to Employees." Because the pro forma disclosure method has been selected, the adoption of SFAS No. 123 will not impact the Company's results of operations or financial position. 3.

An ownership change, as defined in the Internal Revenue Code, may limit the amount of net operating loss and tax credit carryforwards which can be utilized annually to offset future taxable income or tax liability. The amount of the annual limitation is determined based upon the Company's value immediately prior to the ownership change. Future ownership changes may affect the limitation in future years. 10. Common Stock Warrants On December 15, 1994, the Company entered into a financial advisory agreement with an investment banking and brokerage firm. The compensation agreement with this financial advisor included a five-year warrant to purchase up to 180,000 shares of the common stock of the Company at prices ranging from $2.00 to $4.00 per share. The Company ascribed a value of $75,000 to such warrants which was expensed over the one year term of the agreement. 11. Stock Option and Stock Purchase Plan In June 1989, the Company adopted the 1989 Stock Option and Stock Purchase Plan (the "Plan") which was amended in August 1992 to comply with Section 16 of the Securities and Exchange Act of 1934 and to make certain other changes. Under the Plan, officers, employees and certain other individuals may be awarded shares of common stock or granted options and rights to purchase up to 768,499 shares of common stock. Options granted may be either incentive stock options or non-qualified options. As of May 31, 1996, 152,349 shares are available for future grant. Incentive stock options may be granted to any employee at an exercise price per share of not less than the fair market value per common share on the date of such grant as determined by the board of directors (not less than 110% of such value in the case of holders of 10% or more of the total combined voting power of all classes of the Company's stock). Non-qualified options may be granted to any employee, officer, director or consultant at an exercise price per share of not less than the lesser of book value per common share or fifty percent of the fair market value per common share on the date of grant. All options under the Plan are exercisable over periods determined by the board of directors, not to exceed ten years from the date of grant (five years in the case of incentive stock options granted to holders of 10% or more of the total combined voting power of all classes of the Company's stock). The duration of options granted under the Plan has generally been six to ten years. In the event of termination of the optionee's relationship with the Company, options not yet exercised terminate 90 days from the optionee's termination date unless otherwise specified in the agreement.

Related Party Transactions In March 1991, the Company entered into a distribution agreement with a corporate stockholder. The agreement entitled the stockholder to exclusively distribute the Company's labeled products to individual country distributors in certain European countries. Under the agreement, the Company is required to sell its products to the distributor at 50% of the Company's current United States list price. Effective September 1, 1996 the agreement has been amended so that Endogen will distribute its products directly to individual country distibutors in Europe. The shockholder will continue as Endogen's exclusive distributor in Germany. Sales under this agreement and accounts receivable from this stockholder are reflected on the statement of operations and the balance sheet, respectively. The Company paid a director of the Company $38,000, $112,000 and $47,000 under a consulting contract in fiscal 1994, 1995, and 1996, respectively. 15.
