Explanation of Responses:

( 1 )Pursuant to the Agreement and Plan of Merger, dated as of October 11, 2018 (the "Merger Agreement"), between Corium International, Inc. (the "Company"), Gurnet Holding Company ("Parent") and Gurnet Merger Sub, Inc., a wholly-owned subsidiary of Parent ("Merger Sub"), Merger Sub was merged with and into the Company, with the Company continuing as the surviving corporation and a wholly-owned subsidiary of Parent (the "Merger"). Pursuant to the Merger Agreement, at the effective time of the Merger, each issued and outstanding share of common stock, par value $0.001 per share, of the Company (each, a "Share") was converted into the right to receive (i) $12.50 per Share in cash, plus (ii) one non-transferable contingent value right per Share, which represents the contractual right to receive $0.50 per Share in cash (a "CVR"). ( 2 )Includes 257 shares acquired under the Issuer's employee stock purchase plan on November 19, 2018. ( 3 )Pursuant to the Merger Agreement, at the effective time of the Merger, each option to purchase Shares that was vested and outstanding was cancelled and converted into the right to receive (i) an amount in cash equal to the product of (x) the number of vested Shares issuable under such option multiplied by (y) the excess of (A) $12.50 over (B) the per share exercise price of such option, plus (ii) one CVR for each Share issuable under such option. This option is fully vested. ( 4 )Pursuant to the Merger Agreement, at the effective time of the Merger, each unvested option to purchase Shares that was unexpired, unexercised and outstanding was converted into and substituted for the right to receive an amount equal to the product of (x) the number of unvested Shares issuable under such option multiplied by (y) the excess of (A) $12.50 over (B) the per share exercise price of such option. This consideration will be paid monthly in accordance with the monthly vesting schedule that originally was applicable to such option. ( 5 )Pursuant to the Merger Agreement, at the effective time of the Merger, each unvested RSU outstanding that had not yet been settled was converted into and substituted for the right to receive an amount equal to the product of (x) the number of Shares issuable under such RSU multiplied by $12.50. This consideration will be paid annually in accordance with the annual vesting schedule that originally was applicable to such RSU.
