POWER OF ATTORNEY
I, Frank Neumann, hereby authorize and designate Robert E. Gagnon as my true and lawful attorney-in-fact to:
(1) execute for and on my behalf, in my capacity as an officer of Verastem, Inc. (the "Company"), Form ID and Forms 3, 4 and 5, in accordance with Section 16(a) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act") and the rules and regulations promulgated thereunder;
(2) do and perform any and all acts for and on my behalf which may be necessary or desirable to complete and execute any such Form ID or Form 3, 4 or 5, complete and
execute any amendment or amendments thereto, and timely file such form with the Securities and Exchange Commission, any stock exchange or similar authority; and
(3) take any other action of any type whatsoever in connection with the foregoing which, in the opinion of such attorney-in-fact, may be to my benefit, in my best
interest, or legally required of me, it being understood that the documents executed by such attorney-in-fact on my behalf pursuant to this Power of Attorney shall be in such form and shall contain such terms and conditions as such
attorney-in-fact may approve in such attorney-in-fact's discretion.
I hereby further grant to each such attorney-in-fact full power and authority to do and perform any and every act and thing
whatsoever requisite, necessary, or proper to be done in the exercise of any of the rights and powers herein granted, as fully to all intents and purposes as I might or could do if personally present, with full power of substitutes or revocation,
hereby ratifying and confirming all that such attorney-in fact, or such attorney-in-fact's substitute or substitutes, shall lawfully do or cause to be done by virtue of this Power of Attorney and the rights and powers herein granted. I hereby
acknowledge that the foregoing attorney-in-fact, in serving in such capacity at my request, is not assuming, nor is the Company assuming, any of my responsibilities to comply with Section 16 of the Exchange Act.
This Power of Attorney shall remain in full force and effect until I am no longer required to file Forms 3, 4 and 5 with
respect to my holdings of and transactions in securities issued by the Company, unless earlier revoked by me in a signed writing delivered to the foregoing attorney-in-fact.
IN WITNESS WHEREOF, I have caused this Power of Attorney to be duly executed as of this 30th day of December, 2020.
