1 T CELL SCIENCES, INC. UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS The following unaudited financial statements have been derived from statements previously presented in the Company's Annual Report on Form 10-K for the year ended December 31, 1994, and the Company's Quarterly Report on Form 10-Q for the Quarter and Nine Months Ended September 30, 1995, and should be read in conjunction with the financial statements and notes thereto included in such reports. The unaudited balance sheet presents the financial position of the Company as of September 30, 1995 assuming the sale of certain of the assets of the research products and operations (the "Assets") of its wholly-owned subsidiary T Cell Diagnostics, Inc. to Endogen, Inc. ("Endogen") had occurred on that date. In addition, the unaudited statements of operations for the year ended December 31, 1994 and the nine months ended September 30, 1995 present the results of operations of the Company for the periods then ended assuming the sale of the Assets had occurred immediately prior to commencement of the statement of operations period. The unaudited pro forma adjustments are based upon available information and certain assumptions that management believes are reasonable in the circumstances. The unaudited pro forma consolidated financial information neither purports to represent what the Company's financial position or results of operations would actually have been if the sale of the Assets to Endogen had occurred on January 1, 1994, January 1, 1995 or September 30, 1995 nor to project the Company's financial position or results of operations for any future date or period. 2 T CELL SCIENCES, INC.
