Explanation of Responses:
( 1)	This filing is being amended to adjust the number of shares of Common Stock (hereinafter defined) beneficially owned as reported in Table I, Box 2 which were previously reported as 4,617,045. The adjusted amount for Box 2 of Table I is 4,611,921.
( 2)	This adjustment results from the failure of certain shareholders to deliver 5,124 shares of Common Stock tendered pursuant to notices of guaranteed delivery, as executed in conjunction with a tender offer by Eclipse Acquisition Corp. ("Purchaser"), a wholly-owned subsidiary of Pfizer Inc. ("Parent"), for all of the issued and outstanding common stock, $0.001 par value per share (the "Common Stock") of Icagen, Inc.
( 3)	The shares are owned directly by Purchaser. The shares may also be deemed to be indirectly beneficially owned by Parent.
