IMMUNOGEN, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

A.    Summary of Significant Accounting Policies

Basis of Presentation

        The accompanying consolidated financial statements at December 31, 2001 and June 30, 2001 and for the three-month and six-month periods ended December 31, 2001 and 2000 include the accounts of the Company and its subsidiaries, ImmunoGen Securities Corp. and Apoptosis Technology, Inc. (ATI). Although the consolidated financial statements are unaudited, they include all of the adjustments, consisting only of normal recurring adjustments, which management considers necessary for a fair presentation of the Company's financial position in accordance with generally accepted accounting principles for interim financial information. Certain information and footnote disclosures normally included in the Company's annual financial statements have been condensed or omitted. The preparation of interim financial statements requires the use of management's estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the interim financial statements and the reported amounts of revenues and expenditures during the reported period. The results of the interim periods are not necessarily indicative of the results for the entire year. Accordingly, the interim financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended June 30, 2001.

Revenue Recognition

        The Company enters into licensing and development agreements with collaborative partners for the development of monoclonal antibody-based cancer therapeutics. The terms of the agreements typically include non-refundable license fees, payments based upon the achievement of certain milestones and royalties on product sales.

        Prior to June 30, 2000, the Company recognized collaboration revenue on up-front, non-refundable license payments upon receipt and milestone payments upon achievement of the milestone and when collection was probable. Revenues recognized were based on the collaboration agreement milestone value and the relationship of costs incurred to the Company's estimates of total cost expected to complete that milestone.

        Effective July 1, 2000, the Company changed its method of accounting for revenue recognition in accordance with Staff Accounting Bulletin No. 101, "Revenue Recognition in Financial Statements," (SAB 101). Under the new accounting method, adopted retroactively to July 1, 2000, the Company recognizes revenue from non-refundable, up-front license payments, not specifically tied to a separate earnings process, ratably over the term of the research contract. The cumulative effect of the change in accounting principle on prior years resulted in a non-cash charge to income of $5.7 million, which is included in the net loss for the six months ended December 31, 2000. Results for the three and six months ended December 31, 2000 have been restated for the retroactive adoption of SAB 101. Included in revenue for each of the three-month and six-month periods ended December 31, 2001 and 2000 is $219,000 and $438,000, respectively, of revenue that was recognized in prior years, before the Company's adoption of SAB 101, and included in the cumulative effect of change in accounting principle.

Marketable Securities

        In accordance with the Company's investment policy, surplus cash is invested in investment-grade corporate and U.S. Government debt securities typically with maturity dates of less than one year. The Company designates its marketable securities as available-for-sale securities. Effective September 30,

6



2001, the Company has classified all such securities as current assets since the Company has the ability to use such securities to satisfy current liabilities. Marketable securities continue to be carried at their fair value with unrealized gains and losses included in accumulated other comprehensive income in the accompanying balance sheet.

Inventory

        Inventory costs primarily relate to clinical trial materials being manufactured for the Company's collaborators. Inventory is stated at the lower of cost or market.

        Inventory at December 31, 2001 is summarized below:

Raw materials   $ 1,347,472
Work in process     1,919,551
Finished goods     1,275,780
   
Total   $ 4,542,803
   

Computation of Net Loss Per Common Share

        Basic and diluted net earnings/loss per share is calculated based upon the weighted average number of common shares outstanding during the period. Diluted net loss per share incorporates the dilutive effect of stock options, warrants and other convertible securities. Common stock equivalents, as calculated in accordance with the treasury-stock accounting method, equaled 3,874,294 and 5,329,604 for the three months ended December 31, 2001 and 2000, respectively, and 3,870,987 and 5,102,868 for the six months ended December 31, 2001 and 2000, respectively. Common stock equivalents have not been included in the net loss per share calculations for the three- and six-month periods ended December 31, 2001 and 2000 because their effect is anti-dilutive.

Comprehensive Loss

        The Company presents comprehensive loss in accordance with Statement of Financial Accounting Standards (SFAS) No. 130, "Reporting Comprehensive Income." For the three-month and six-month periods ended December 31, 2001, total comprehensive loss equaled $2,279,006 and $2,953,609, respectively. For the three and six months ended December 31, 2000, total comprehensive loss equaled $2,164,669 and $9,896,051, respectively. Comprehensive loss was comprised entirely of net loss and net unrealized losses recognized on available-for-sale debt securities.

Recent Accounting Pronouncements

        In October 2001, the Financial Accounting Standards Board issued SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets." SFAS No. 144 supersedes SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed of" and provides a single accounting model for long-lived assets to be disposed of. The provisions of SFAS No. 144 are effective for fiscal years beginning after December 15, 2001. Management does not believe the adoption of SFAS No. 144 will have a material effect on the Company's financial position or results of operations.

Reclassifications

        Certain prior year balances have been reclassified to conform to current year presentation.

7



B.    Agreements

        In November 2001, the Company and Boehringer Ingelheim International GmbH, (BI), of Ingelheim, Germany entered into a collaboration to develop a new product combining the Company's maytansinoid TAP technology with a BI antibody. Under the terms of the agreement, the Company received an up-front payment and could receive, based upon the exchange rate on November 27, 2001, the effective date of the agreement, approximately $41.5 million, in potential payments upon BI's achievement of certain milestones in addition to royalty payments on future product sales, if and when they commence. The up-front fee was received in December 2001 and will be recognized ratably over the Company's period of involvement during development. BI is responsible for the manufacturing, product development and marketing of any products resulting from the collaboration. The Company will be reimbursed for any preclinical and initial clinical materials that it manufactures under the agreement.

C.    Capital Stock

        At December 31, 2001, excluding the warrants issued to BioChem Pharma, Inc., discussed below, warrants to acquire 1,828,928 shares of common stock remained outstanding at exercise prices ranging from $2.31 to $38.00. These warrants were originally issued in connection with the Company's March 1996 private placement of convertible debt, the private placements of the Company's Series A, Series B and Series C preferred stock and a warrant issued in connection with the Company's November 2000 public offering in satisfaction of anti-dilution provisions of certain warrants then outstanding.

        As part of the BioChem agreement, BioChem received warrants to purchase shares of ImmunoGen common stock equal to the amount invested in ATI during the three-year research term. Beginning July 31, 2000, these warrants became exercisable for a number of shares of ImmunoGen common stock determined by dividing $11.1 million, the amount of BioChem's investment in ATI, by the market price of ImmunoGen common stock on the exercise date, subject to certain limitations imposed by the Nasdaq Stock Market rules, which limit the sale or issuance by an issuer of certain securities at a price less than the greater of book or market value of such securities. Consequently, BioChem's ability to convert all of its ImmunoGen warrants into ImmunoGen common stock is limited to a total of 20% of the number of shares of ImmunoGen's common stock outstanding on the date of the initial transaction if the conversion price is less than the market price of ImmunoGen common stock on that date, unless stockholder approval for such conversion is obtained, if required, or unless the Company has obtained a waiver of that requirement. The exercise price is payable in cash or shares of ATI's preferred stock, at BioChem's option. The warrants are expected to be exercised only in the event that the shares of ATI common stock do not become publicly traded. ImmunoGen expects that BioChem will use its shares of ATI preferred stock, in lieu of cash, to exercise the warrants.

        In September 2001, a holder of warrants originally issued in connection with the March 1996 private placement of the Company's convertible debentures and subsequently adjusted, pursuant to the anti-dilution provisions of the warrants, in connection with the Company's November 2000 public offering of common stock, exercised its right to acquire 1,127,374 shares of common stock at prices ranging between $3.58 and $5.37 per share. Proceeds from these warrant exercises will be used to fund current operations.

        In October 2001, a holder of warrants originally issued in connection with a private placement of the Company's Series B convertible preferred stock exercised its right to acquire 10,931 shares of common stock at $5.49 per share. Proceeds from this warrant exercise will be used to fund current operations.

        In November 2001, the Company's shareholders approved an increase in the amount of the authorized common stock from 50,000,000 to 75,000,000 shares and an amendment to the Company's

8



Restated Stock Option Plan to increase the total number of shares reserved for the grant of options by 2,500,000 to 7,350,000 shares of common stock.

        In November 2001, the Company's shareholders approved the establishment of the 2001 Non-Employee Director Stock Plan (the Director Plan) and 50,000 shares of common stock to be reserved for grant thereunder. The Director Plan provides for the granting of awards to Non-Employee Directors and the election of Non-Employee Directors to have all or a portion of their awards in the form of cash, stock or stock units. All stock or stock units issued pursuant to the Director Plan are immediately vested. The Director Plan is administered by the Board of Directors who is authorized to interpret the provisions of the Director Plan, determine which Non-Employee Directors will be granted awards, and determine the number of shares of stock for which a stock right will be granted.

        During the six-month period ended December 31, 2001, holders of options issued under the Company's Restated Stock Option Plan exercised their rights to acquire an aggregate of 95,169 shares of common stock at prices ranging from $0.84 per share to $15.88 per share. The total proceeds from these option exercises, $499,509, will be used to fund current operations.

D.    Commitments and Contingencies

        In December 1995, the Company entered into an agreement with a third party whereby the third party agreed to identify and introduce potential financing sources to the Company in exchange for cash and warrants upon the successful completion of a financing. During the fiscal years ended June 30, 1996 and 1998, the Company issued stock, warrants and cash to the third party relating to certain financings. On November 13, 2001, the Company received a claim asserting that, as a result of certain warrant exercises, the Company owes additional compensation to the third party in the form of $819,423 in cash and warrants exercisable for the purchase of 250,000 shares of common stock of the Company at $3.11 per share. The Company is currently negotiating with the third party to settle the claim. The Company believes a settlement of the claim is probable and, accordingly, has accrued $2.0 million as the estimated amount of the settlement in the accompanying financial statements. Any settlement will be considered an equity financing fee and will be accounted for as a reduction of the gross proceeds of the financings and will not result in a charge to the Company's statement of operations. Accordingly, the estimated settlement is reflected as a reduction in Additional Paid-in Capital in the accompanying balance sheet.
