RESEARCH PRODUCTS AND OPERATIONS NOTES TO FINANCIAL STATEMENTS 1. FORMATION AND BASIS OF PRESENTATION The Business Under a purchase and sale agreement dated as of March 4, 1996, Endogen, Inc. acquired the research products and operations (the "Business") of T Cell Diagnostics, Inc. ("TCD"), a wholly owned subsidiary of T Cell Sciences, Inc. ("TCS"). The Business develops, manufactures and markets proprietary products used in the research or preclinical diagnostic market. The Business excludes TCD's TRAx(R) diagnostic product franchise which includes TRAx CD4 for CD4 cell enumeration in monitoring HIV infected patients. The Business shares administrative offices with other TCS operations in Needham, Massachusetts. Basis of Presentation These financial statements present the historical financial position, results of operations and cash flows of the Business previously included in the TCS consolidated financial statements. The Securities and Exchange Commission, in Staff Accounting Bulletin No. 5, requires that historical financial statements of a subsidiary, division or lesser business component of another entity include certain expenses incurred by the parent on its behalf (Note 14). Earnings per share calculations are not reflected herein, as this information is not considered meaningful as a result of the Business not being a legal entity, and therefore not having customary equity or capital accounts. Accumulated funding from TCS to the Business is reflected in Parent Company Investment (Note 13). 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (A) Revenue Recognition Revenue from product sales is recognized when the product is shipped. (B) Research and Development Costs Research and development costs are expensed as incurred. (C) Concentration of Credit Risk Financial instruments which potentially expose the Business to concentrations of credit risk consist primarily of trade accounts receivable. To minimize the risk, ongoing credit evaluation of customer's financial condition is performed. (D) Inventories Inventories are stated at the lower of cost or market. Cost is determined using the first-in, first-out (FIFO) method. (E) Property and Equipment Property and equipment is stated at cost and depreciated over the estimated useful lives of the related assets using the straight-line method. Laboratory equipment and office furniture and equipment are depreciated over a five year period and computer equipment is depreciated over a three year period. Leasehold improvements are amortized over the shorter of the estimated useful life or the noncancelable term of the related lease. (F) Licenses, Patents and Trademarks Included in other assets are purchased licenses, patents and trademarks which are capitalized and amortized over the shorter of the estimated useful lives or ten years using the straight-line method. 14 (G) Use of Estimates The preparation of the 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 contingencies at December 31, 1995 and 1994 and the reported amounts of revenue and expense for the years ended December 31, 1995, 1994 and 1993. Actual results could differ from those estimates. 3.

RESEARCH AND LICENSING AGREEMENTS The Business has entered into licensing agreements with several universities and research organizations. Under the terms of these agreements, the Business has received licenses to technology, certain patents or patent applications. The Business is required to make payments of nonrefundable license fees and royalties which amounted to approximately $85,000, $115,000 and $60,000 for the years ended December 31, 1995, 1994 and 1993. 10. FOREIGN SALES AND SALES TO SIGNIFICANT CUSTOMERS Foreign Sales: Product sales were generated geographically as follows: 17 Net Product Sales for the Twelve Months Ended Europe USA Asia Other Total - - --------------------------------------------------------------------------------------------------------------------- December 31, 1995 $ 730,000 $ 964,000 $481,000 $125,000 $2,300,000 December 31, 1994 1,178,000 1,305,000 517,000 32,000 3,032,000 December 31, 1993 1,719,000 1,162,000 419,000 50,000 3,350,000 Sales to Significant Customer: In 1995, the Business had product sales to one customer of 12% of total sales.

In 1993, the Business had sales to one customer of 16% of total sales and to another customer of 12% of total sales. 11. ACQUIRED IN-PROCESS RESEARCH AND DEVELOPMENT In September 1993, the Business acquired approximately $2,100,000 of in-process research and development costs in conjunction with the acquisition of the outstanding minority interest in TCD. In accordance with generally accepted accounting principles, the Business expensed this amount as research and development costs upon acquisition. 12. FACILITY RELOCATION EXPENSE In June 1994, TCS and TCD temporarily vacated their headquarters and manufacturing facility at 38 Sidney Street in Cambridge, Massachusetts due to air quality problems within the building causing certain employees to experience skin and respiratory irritation. During the third quarter of 1994, management determined that it could not return to the building and ensure the protection of its employees' health. As a result, TCD relocated its operating facility to Woburn, Massachusetts. The costs to physically move property and establish computer and telephone networks at alternate sites and other costs directly associated with vacating the Sidney Street location are included as facility relocation expense. 13. PARENT COMPANY INVESTMENT At December 31, 1995, T Cell Diagnostics, Inc. has 1,000 shares authorized, issued and outstanding common stock, $.001 par value and 2,000 shares authorized preferred stock, $.001 par value. Since the Business is not a legal entity, there are no customary equity or capital accounts. Rather, a parent company investment is maintained by the Business and TCS to account for intercompany transactions and related charges and credits as further described in Note 14. No interest has been charged on the parent company investment. A summary of changes in the parent company investment is as follows: Parent company investment at December 31, 1992 1,260,283 Net loss (4,929,035) Capital contribution from parent 4,502,646 - - ---------------------------------------------------------------------------------------------------------- Parent company investment at December 31, 1993 833,894 Net loss (1,972,985) Capital contribution from parent 2,182,272 - - ---------------------------------------------------------------------------------------------------------- Parent company investment at December 31, 1994 1,043,181 Net loss (2,150,767) Capital contribution from parent 2,280,888 - - ---------------------------------------------------------------------------------------------------------- Parent company investment at December 31, 1995 $ 1,173,302 ========================================================================================================== 18 14. RELATED PARTY TRANSACTIONS AND ALLOCATIONS Cash The Business utilized TCS's centralized cash management services. Generally, under such service arrangements, accounts receivable were collected and cash was invested centrally. Additionally, disbursing operations were funded centrally on demand. As a result, the Business carried no cash but received charges and credits against parent company investment for cash used and collected through TCS. Corporate and Divisional Services The Business used, and was charged costs for, certain administrative and accounting services that TCS provided to the Business and to other TCS operations at the corporate administrative offices, including human resources, data processing and legal services. In addition, TCS allocates a portion of its domestic corporate expenses to respective business units. These include TCS executive management and corporate overhead; benefit administration; risk management/insurance administration; tax and treasury/cash management services; litigation administration services; and other support and executive functions. All of the allocations and charges described above are included in general and administrative expenses in these financial statements. Such allocations and charges are based on either a direct cost allocation or a percentage of total costs for the services provided. Such allocations and charges totaled $703,000, $723,000 and $613,000 for the years ended December 31, 1995, 1994 and 1993, respectively. TCS also charges the Business, based on the Business' experience, for its share of workers' compensation, employee life, medical and dental, and other general business liability insurance premiums and claims handled on a corporate-wide basis. These charges are based upon a combination of experience and payroll dollars and totaled $164,000, $124,000 and $177,000 in 1995, 1994 and 1993, respectively and are allocated based on the nature of the function. Management believes that the basis used for allocating corporate and divisional services is reasonable. However, the terms of these transactions may differ from those that would result from transactions among unrelated parties. 19
