Dear Garen:

On behalf of Collegium Pharmaceutical, Inc., a Virginia corporation (the “Company”), I am very pleased to offer you the following terms and conditions in connection with your service on the board of directors (the “Board”) of the Company should you accept this offer.

1.                                      Duties.  You will be appointed to the Board to serve until the earlier of the qualification of your successor or your resignation or removal.  As a member of the Board, you will be expected to serve on the Board and on such committees of the Board as to which you are appointed and agree to serve. The Board presently holds regular meetings about every six weeks and special meetings of the Board occur from time to time as needed. In addition to participating in our Board meetings, we expect that you will provide us with such other assistance so as to help us achieve our goals.

2.                                      Cash Compensation.  In consideration for your regular attendance of meeting of the Board and carrying out other Board duties, the Company will pay you a fee of $10,000 quarterly in arrears (for annualized fee of $40,000). You will also be entitled to reimbursement of your reasonable out-of-pocket travel expenses.

3.                                      Stock Option Award.  Subject to Board approval, the Company will grant to you a non-statutory stock option award for the purchase of up to 200,000 shares of the Company’s Common Stock (the “Option”). The exercise price of the Option will be the fair market value of the Company’s Common Stock on the date of grant.  The Option shall be subject to the following vesting provisions:  Subject to your continued tenure on the Board, the Option shall vest over a period of four (4) years with 1/48th of the total number of shares underling the Option vesting at the end of each monthly period following your election to the Board; provided, however, upon the closing of a Sale Event (as defined below), all of the then unvested shares underlying the Option shall become fully vested.  The Shares shall be subject to the terms and conditions of the Company’s 2014 Stock Incentive Plan and the Company’s form of non-statutory stock option agreement. For purposes of your Option, a “Sale Event” shall mean either: (i) a transaction or series of related transactions in which a person, or a group of related persons, acquires from stockholders of the Company shares representing more than fifty percent (50%) of the outstanding voting power of the Company, or (ii) a transaction that qualifies as a “Deemed Liquidation Event” as defined in the Company’s Articles of Incorporation then in effect.]
