EXPLANATORY NOTE

 

ImmunoGen, Inc. (the “Company”) is filing this post-effective amendment to deregister certain of the securities originally registered pursuant to the Registration Statement on Form S-8 (File No. 333-75372), filed with the Securities and Exchange Commission on December 18, 2001 by the Company (the “Registration Statement”) with respect to shares of the Company’s common stock, par value $0.01 per share (“Common Stock”), thereby registered for issuance under the Company’s Restated Stock Option Plan, as amended (the “Restated Stock Option Plan”).  An aggregate of 2,500,000 shares of Common Stock were registered for issuance under the Restated Stock Option Plan pursuant to the Registration Statement.

 

On November 14, 2006, the Company’s shareholders approved the Company’s 2006 Employee, Director and Consultant Equity Incentive Plan (the “2006 Plan”), which replaced the Restated Stock Option Plan as of the date of approval.  Following the approval of the 2006 Plan, no future awards may be made under the Restated Stock Option Plan.  The maximum number of shares of Common Stock reserved and available for issuance under the 2006 Plan includes 500,000 shares available for grant under the Restated Stock Option Plan as of the effective date of the 2006 Plan (the “Original Carried Forward Shares), plus the number of shares underlying any grants previously made under the Restated Stock Option Plan that are forfeited, canceled or terminated (other than by exercise) from and after November 11, 2006.  The Original Carried Forward Shares included 111,245 shares registered under the Registration Statement, which were deregistered pursuant to Post-Effective Amendment No. 1 to the Registration Statement filed on November 30, 2007.  An additional 185,444 shares (the “First Additional Carried Forward Shares”) registered under the Registration Statement have been included in the shares reserved for issuance under the 2006 Plan as a result of forfeiture, cancellation or termination (other than by exercise) of previously-made grants under the Restated Stock Option Plan during the period between November 1, 2007 and October 31, 2008, which shares were deregistered pursuant to Post-Effective Amendment No. 2 to the Registration Statement filed on November 21, 2008.  An additional 356,408 shares (the “Second Additional Carried Forward Shares”) have been included in the shares reserved for issuance under the 2006 Plan as a result of forfeiture, cancellation or termination (other than by exercise) of previously-made grants under the Restricted Stock Option Plan during the period between November 1, 2008 and October 31, 2010.  The Second Additional Carried Forward Shares were registered under the Registration Statement, and are hereby deregistered.  Additional shares reserved for issuance under the Restated Stock Option Plan may become available in the future as a result of the forfeiture, cancellation or termination of awards (other than by exercise) under the Restated Stock Option Plan, and these additional shares will be included in the shares reserved for issuance under the 2006 Plan.

 

Contemporaneously with the filing of this Post-Effective Amendment No. 3 to the Registration Statement, the Company is filing a Registration Statement on Form S-8 to register the Second Additional Carried Forward Shares for issuance pursuant to the 2006 Plan.
