ImmunoGen Announces Inducement Grants Under Nasdaq Listing Rule 5635(c)(4) - May 02, 2022

The Inducement Plan is used exclusively for the grant of equity awards to individuals who were not previously employees of ImmunoGen (or following a bona fide period of non-employment), as an inducement material to such individual’s entering into employment with ImmunoGen, pursuant to Rule 5635(c)(4) of the Nasdaq Listing Rules.

The options have an exercise price of $4.83 per share, which is equal to the closing price of ImmunoGen’s common stock on the Nasdaq Global Select Market on April 29, 2022. Each option will vest over a four-year period, with 25% of the shares vesting on the one-year anniversary of the date of grant, and thereafter an additional 6.25% of the shares vesting on each succeeding quarterly anniversary of the date of grant, subject to such employee’s continued employment with ImmunoGen on such vesting dates. Each option is subject to the terms and conditions of the Inducement Plan and the terms and conditions of a stock option agreement covering the grant.
