C4 THERAPEUTICS, INC. 

[FORM OF] OFFICER INDEMNIFICATION AGREEMENT 

This Indemnification Agreement (“Agreement”) is made as of [Date] by and between C4 Therapeutics, Inc., a Delaware
corporation (the “Company”), and [Officer Name] (“Indemnitee”). 1 

RECITALS 
 WHEREAS, the Company
desires to attract and retain the services of highly qualified individuals, such as Indemnitee, to serve the Company; 
 WHEREAS, in order
to induce Indemnitee to provide or continue to provide services to the Company, the Company wishes to provide for the indemnification of, and advancement of expenses to, Indemnitee to the maximum extent permitted by law; 

WHEREAS, the Amended and Restated Certificate of Incorporation (as amended and in effect from time to time, the “Charter”)
and the Amended and Restated Bylaws (as amended and in effect from time to time, the “Bylaws”) of the Company require indemnification of the officers and directors of the Company, and Indemnitee may also be entitled to
indemnification pursuant to the General Corporation Law of the State of Delaware (the “DGCL”); 
 WHEREAS, the Charter, the
Bylaws and the DGCL expressly provide that the indemnification provisions set forth therein are not exclusive, and thereby contemplate that contracts may be entered into between the Company and members of the board of directors, officers and other
persons with respect to indemnification; 
 WHEREAS, the Board of Directors of the Company (the “Board”) has determined
that the increased difficulty in attracting and retaining highly qualified persons such as Indemnitee is detrimental to the best interests of the Company’s stockholders; 

WHEREAS, it is reasonable and prudent for the Company contractually to obligate itself to indemnify, and to advance expenses on behalf of,
such persons to the fullest extent permitted by applicable law, regardless of any amendment or revocation of the Charter or the Bylaws, so that they will serve or continue to serve the Company free from undue concern that they will not be so
indemnified; and 
 WHEREAS, this Agreement is a supplement to and in furtherance of the indemnification provided in the Charter, the Bylaws
and any resolutions adopted pursuant thereto, and shall not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder. 

NOW, THEREFORE, in consideration of the premises and the covenants contained herein, the Company and Indemnitee do hereby covenant and agree
as follows: 
  

	1 	 NTD: To be entered into with all C-level officers and Section 16
officers. 

 Section 1. Services to the Company. Indemnitee agrees to [continue to] serve as
[a director and] an officer of the Company. Indemnitee may at any time and for any reason resign from [any] such position (subject to any other contractual obligation or any obligation imposed by law), in which event the Company shall have no
obligation under this Agreement to continue Indemnitee in such position. This Agreement shall not be deemed an employment contract between the Company (or any of its subsidiaries or any Enterprise) and Indemnitee.

entity (or its ultimate parent, if applicable) immediately upon completion of such transaction, (iii) the sale of all of the Stock of the Company to an unrelated person, entity or group thereof acting in concert, or (iv) any other
transaction in which the owners of the Company’s outstanding voting power immediately prior to such transaction do not own at least a majority of the outstanding voting power of the Company or any successor entity immediately upon completion of
the transaction other than as a result of the acquisition of securities directly from the Company. 
 (b) “Corporate Status”
describes the status of a person as a current or former [director or] officer of the Company or current or former director, manager, partner, officer, employee, agent or trustee of any other Enterprise which such person is or was serving at the

 (f) “Independent Counsel” means a law firm, or a partner (or, if
applicable, member or shareholder) of such a law firm, that is experienced in matters of Delaware corporation law and neither presently is, nor in the past five (5) years has been, retained to represent: (i) the Company, any subsidiary of
the Company, any Enterprise or Indemnitee in any matter material to any such party; or (ii) any other party to the Proceeding giving rise to a claim for indemnification hereunder. Notwithstanding the foregoing, the term “Independent
Counsel” shall not include any person who, under the applicable standards of professional conduct then prevailing, would have a conflict of interest in representing either the Company or Indemnitee in an action to determine Indemnitee’s
rights under this Agreement. The Company agrees to pay the reasonable fees and expenses of the Independent Counsel referred to above and to fully indemnify such counsel against any and all expenses, claims, liabilities and damages arising out of or
relating to this Agreement or its engagement pursuant hereto. 
 (g) The term “Proceeding” shall include any threatened,
pending or completed action, suit, arbitration, alternate dispute resolution mechanism, investigation, inquiry, administrative hearing or any other actual, threatened or completed proceeding, whether brought in the right of the Company or otherwise
and whether of a civil, criminal, administrative, regulatory or investigative nature, and whether formal or informal, in which Indemnitee was, is or will be involved as a party or otherwise by reason of the fact that Indemnitee is or was [a director
or] an officer of the Company or is or was serving at the request of the Company as a director, manager, partner, officer, employee, agent or trustee of any Enterprise or by reason of any action taken by Indemnitee or of any action taken on his or
her part while acting as [a director or] an officer of the Company or while serving at the request of the Company as a director, manager, partner, officer, employee, agent or trustee of any Enterprise, in each case whether or not serving in such
capacity at the time any liability or expense is incurred for which indemnification, reimbursement or advancement of expenses can be provided under this Agreement; provided, however, that the term “Proceeding” shall not
include any action, suit or arbitration, or part thereof, initiated by Indemnitee to enforce Indemnitee’s rights under this Agreement as provided for in Section 12(a) of this Agreement. 

Section 3. Indemnity in Third-Party Proceedings. The Company shall indemnify Indemnitee to the extent set forth in this
Section 3 if Indemnitee is, or is threatened to be made, a party to or a participant in any Proceeding, other than a Proceeding by or in the right of the Company to procure a judgment in its favor. Pursuant to this Section 3, Indemnitee
shall be indemnified against all Expenses, judgments, fines, penalties, excise taxes, and amounts paid in settlement actually and reasonably incurred by Indemnitee or on his or her behalf in connection with such Proceeding or any claim, issue or
matter therein, if Indemnitee acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the Company and, in the case of a criminal proceeding, had no reasonable cause to believe that his or
her conduct was unlawful. 

  
 3 

 Section 4. Indemnity in Proceedings by or in the Right of the Company. The
Company shall indemnify Indemnitee to the extent set forth in this Section 4 if Indemnitee is, or is threatened to be made, a party to or a participant in any Proceeding by or in the right of the Company to procure a judgment in its favor.
Pursuant to this Section 4, Indemnitee shall be indemnified against all Expenses actually and reasonably incurred by Indemnitee or on his or her behalf in connection with such Proceeding or any claim, issue or matter therein, if Indemnitee
acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the Company. No indemnification for Expenses shall be made under this Section 4 in respect of any claim, issue or matter as to
which Indemnitee shall have been finally adjudged by a court to be liable to the Company, unless and only to the extent that the Delaware Court of Chancery (the “Delaware Court”) shall determine upon application that, despite the
adjudication of liability but in view of all the circumstances of the case, Indemnitee is fairly and reasonably entitled to indemnification for such expenses as the Delaware Court shall deem proper. 

Section 5. Indemnification for Expenses of a Party Who is Wholly or Partly Successful. Notwithstanding any other provisions of
this Agreement and except as provided in Section 7, to the extent that Indemnitee is a party to or a participant in any Proceeding and is successful in such Proceeding or in defense of any claim, issue or matter therein, the Company shall
indemnify Indemnitee against all Expenses actually and reasonably incurred by him or her in connection therewith. If Indemnitee is not wholly successful in such Proceeding but is successful as to one or more but less than all claims, issues or
matters in such Proceeding, the Company shall indemnify Indemnitee against all Expenses actually and reasonably incurred by Indemnitee or on his or her behalf in connection with each successfully resolved claim, issue or matter. For purposes of this
Section and without limitation, the termination of any claim, issue or matter in such a Proceeding by dismissal, with or without prejudice, shall be deemed to be a successful result as to such claim, issue or matter. 

Section 6. Reimbursement for Expenses of a Witness or in Response to a Subpoena. Notwithstanding any other provision of this
Agreement, to the extent that Indemnitee, by reason of his or her Corporate Status, (i) is a witness in any Proceeding to which Indemnitee is not a party and is not threatened to be made a party or (ii) receives a subpoena with respect to
any Proceeding to which Indemnitee is not a party and is not threatened to be made a party, the Company shall reimburse Indemnitee for all Expenses actually and reasonably incurred by him or her or on his or her behalf in connection therewith. 

Section 7. Exclusions. Notwithstanding any provision in this Agreement to the contrary, the Company shall not be obligated under
this Agreement: 
 (a) to indemnify for amounts otherwise indemnifiable hereunder (or for which advancement is provided hereunder) if and to
the extent that Indemnitee has otherwise actually received such amounts under any insurance policy, contract, agreement or otherwise; 
 (b)
to indemnify for an accounting of profits made from the purchase and sale (or sale and purchase) by Indemnitee of securities of the Company within the meaning of Section 16(b) of the Securities Exchange Act of 1934, as amended, or similar
provisions of state statutory law or common law, or from the purchase or sale by Indemnitee of such securities in violation of Section 306 of the Sarbanes-Oxley Act of 2002 (“SOX”); 

  
 4 

 (c) to indemnify for any reimbursement of, or payment to, the Company by Indemnitee of any
bonus or other incentive-based or equity-based compensation or of any profits realized by Indemnitee from the sale of securities of the Company pursuant to Section 304 of SOX or any formal policy of the Company adopted by the Board (or a
committee thereof), or any other remuneration paid to Indemnitee if it shall be determined by a final judgment or other final adjudication that such remuneration was in violation of law;  

(d) to indemnify with respect to any Proceeding, or part thereof, brought by Indemnitee against the Company, any legal entity which it
controls, any director or officer thereof or any third party, unless (i) the Board has consented to the initiation of such Proceeding or part thereof and (ii) the Company provides the indemnification, in its sole discretion, pursuant to
the powers vested in the Company under applicable law; provided, however, that this Section 7(d) shall not apply to (A) counterclaims or affirmative defenses asserted by Indemnitee in an action brought against Indemnitee or
(B) any action brought by Indemnitee for indemnification or advancement from the Company under this Agreement or under any directors’ and officers’ liability insurance policies maintained by the Company in the suit for which
indemnification or advancement is being sought as described in Section 12; or 
 (e) to provide any indemnification or advancement of
expenses that is prohibited by applicable law (as such law exists at the time payment would otherwise be required pursuant to this Agreement). 

Section 8. Advancement of Expenses. Subject to Section 9(b), the Company shall advance, to the extent not prohibited by law,
the Expenses incurred by Indemnitee in connection with any Proceeding, and such advancement shall be made as incurred, and such advancement shall be made within thirty (30) days after the receipt by the Company of a statement or statements
requesting such advances (including any invoices received by Indemnitee, which such invoices may be redacted as necessary to avoid the waiver of any privilege accorded by applicable law) from time to time, whether prior to or after final disposition
of any Proceeding. Advances shall be unsecured and interest free. Advances shall be made without regard to Indemnitee’s (i) ability to repay the expenses, (ii) ultimate entitlement to indemnification under the other provisions of this
Agreement, and (iii) entitlement to and availability of insurance coverage, including advancement, payment or reimbursement of defense costs, expenses of covered loss under the provisions of any applicable insurance policy (including , without
limitation, whether such advancement, payment or reimbursement is withheld, conditioned or delayed by the insurer(s)). Indemnitee shall qualify for advances upon the execution and delivery to the Company of this Agreement which shall constitute an
undertaking providing that Indemnitee undertakes to the fullest extent required by law to repay the advance if and to the extent that it is ultimately determined by a court of competent jurisdiction in a final judgment, not subject to appeal, that
Indemnitee is not entitled to be indemnified by the Company. The right to advances under this paragraph shall in all events continue until final disposition of any Proceeding, including any appeal therein. Nothing in this Section 8 shall limit
Indemnitee’s right to advancement pursuant to Section 12(e) of this Agreement.

 Section 9. Procedure for Notification and Defense of Claim. 

(a) To obtain indemnification under this Agreement, Indemnitee shall submit to the Company a written request therefor specifying the basis for
the claim, the amounts for which Indemnitee is seeking payment under this Agreement, and all documentation related thereto as reasonably requested by the Company. 

(b) In the event that the Company shall be obligated hereunder to provide indemnification for or make any advancement of Expenses with respect
to any Proceeding, the Company shall be entitled to assume the defense of such Proceeding, or any claim, issue or matter therein, with counsel approved by Indemnitee (which approval shall not be unreasonably withheld or delayed) upon the delivery to
Indemnitee of written notice of the Company’s election to do so. After delivery of such notice, approval of such counsel by Indemnitee and the retention of such counsel by the Company, the Company will not be liable to Indemnitee under this
Agreement for any fees or expenses of separate counsel subsequently employed by or on behalf of Indemnitee with respect to the same Proceeding; provided that (i) Indemnitee shall have the right to employ separate counsel in any such
Proceeding at Indemnitee’s expense and (ii) if (A) the employment of separate counsel by Indemnitee has been previously authorized by the Company, (B) Indemnitee shall have reasonably concluded that there may be a conflict of interest
between the Company and Indemnitee in the conduct of such defense, or (C) the Company shall not continue to retain such counsel to defend such Proceeding, then the fees and expenses actually and reasonably incurred by Indemnitee with respect to
his or her separate counsel shall be Expenses hereunder. 
 (c) In the event that the Company does not assume the defense in a Proceeding
pursuant to paragraph (b) above, then the Company will be entitled to participate in the Proceeding at its own expense. 
 (d) The
Company shall not be liable to indemnify Indemnitee under this Agreement for any amounts paid in settlement of any Proceeding effected without its prior written consent (which consent shall not be unreasonably withheld or delayed). The Company shall
not, without the prior written consent of Indemnitee (which consent shall not be unreasonably withheld or delayed), enter into any settlement which (i) includes an admission of fault of Indemnitee, any
non-monetary remedy imposed on Indemnitee or any monetary damages for which Indemnitee is not wholly and actually indemnified hereunder or (ii) with respect to any Proceeding with respect to which
Indemnitee may be or is made a party or may be otherwise entitled to seek indemnification hereunder, does not include the full release of Indemnitee from all liability in respect of such Proceeding. 

Section 10. Procedure Upon Application for Indemnification.2 

(a) Upon written request by Indemnitee for indemnification pursuant to Section 9(a), a determination, if such determination is required by
applicable law, with respect to Indemnitee’s entitlement to indemnification hereunder shall be made in the specific case by one of the following methods: [(x) if a Change in Control shall have occurred and indemnification is

being requested by Indemnitee hereunder in his or her capacity as a director of the Company, by Independent Counsel in a written opinion to the Board; or (y) in any other case,] (i) by a
majority vote of the disinterested directors, even though less than a quorum; (ii) by a committee of disinterested directors designated by a majority vote of the disinterested directors, even though less than a quorum; or (iii) if there
are no disinterested directors or if the disinterested directors so direct, by Independent Counsel in a written opinion to the Board. For purposes hereof, disinterested directors are those members of the Board who are not parties to the action, suit
or proceeding in respect of which indemnification is sought. In the case that such determination is made by Independent Counsel, a copy of Independent Counsel’s written opinion shall be delivered to Indemnitee and, if it is so determined that
Indemnitee is entitled to indemnification, payment to Indemnitee shall be made within thirty (30) days after such determination. Indemnitee shall cooperate with the Independent Counsel or the Company, as applicable, in making such determination
with respect to Indemnitee’s entitlement to indemnification, including providing to such counsel or the Company, upon reasonable advance request, any documentation or information which is not privileged or otherwise protected from disclosure
and which is reasonably available to Indemnitee and reasonably necessary to such determination. Any out-of-pocket costs or expenses (including reasonable attorneys’
fees and disbursements) actually and reasonably incurred by Indemnitee in so cooperating with the Independent Counsel or the Company shall be borne by the Company (irrespective of the determination as to Indemnitee’s entitlement to
indemnification) and the Company hereby indemnifies and agrees to hold Indemnitee harmless therefrom. 
 (b) If the determination of
entitlement to indemnification is to be made by Independent Counsel pursuant to Section 10(a), the Independent Counsel shall be selected by the Board[; provided that, if a Change in Control shall have occurred and indemnification is
being requested by Indemnitee hereunder in his or her capacity as a director of the Company, the Independent Counsel shall be selected by Indemnitee]. Indemnitee [or the Company, as the case may be,] may, within ten (10) days after written
notice of such selection, deliver to the Company [or Indemnitee, as the case may be,] a written objection to such selection; provided, however, that such objection may be asserted only on the ground that the Independent Counsel so
selected does not meet the requirements of “Independent Counsel” as defined in Section 2 of this Agreement, and the objection shall set forth with particularity the factual basis of such assertion. Absent a proper and timely
objection, the person so selected shall act as Independent Counsel. If such written objection is so made and substantiated, the Independent Counsel so selected may not serve as Independent Counsel unless and until such objection is withdrawn or the
Delaware Court has determined that such objection is without merit. If, within twenty (20) days after the later of (i) submission by Indemnitee of a written request for indemnification pursuant to Section 9(a), and (ii) the final
disposition of the Proceeding, including any appeal therein, no Independent Counsel shall have been selected without objection, either Indemnitee or the Company may petition the Delaware Court for resolution of any objection which shall have been
made by Indemnitee or the Company to the selection of Independent Counsel and/or for the appointment as Independent Counsel of a person selected by the court or by such other person as the court shall designate. The person with respect to whom all
objections are so resolved or the person so appointed shall act as Independent Counsel under Section 10(a) hereof. Upon the due commencement of any judicial proceeding or arbitration pursuant to Section 12(a) of this Agreement, Independent
Counsel shall be discharged and relieved of any further responsibility in such capacity (subject to the applicable standards of professional conduct then prevailing).

 Section 11. Presumptions and Effect of Certain Proceedings. 

(a) To the extent permitted by applicable law, in making a determination with respect to entitlement to indemnification hereunder, it shall be
presumed that Indemnitee is entitled to indemnification under this Agreement if Indemnitee has submitted a request for indemnification in accordance with Section 9(a) of this Agreement, and the Company shall have the burden of proof to overcome
that presumption in connection with the making of any determination contrary to that presumption. Neither (i) the failure of the Company or of Independent Counsel to have made a determination prior to the commencement of any action pursuant to
this Agreement that indemnification is proper in the circumstances because Indemnitee has met the applicable standard of conduct, nor (ii) an actual determination by the Company or by Independent Counsel that Indemnitee has not met such
applicable standard of conduct, shall be a defense to the action or create a presumption that Indemnitee has not met the applicable standard of conduct. 

(b) The termination of any Proceeding or of any claim, issue or matter therein, by judgment, order, settlement or conviction, or upon a plea of
guilty, nolo contendere or its equivalent, shall not (except as otherwise expressly provided in this Agreement) of itself adversely affect the right of Indemnitee to indemnification or create a presumption that Indemnitee did not act
in good faith and in a manner which he or she reasonably believed to be in or not opposed to the best interests of the Company or, with respect to any criminal Proceeding, that Indemnitee had reasonable cause to believe that his or her conduct was
unlawful. 
 (c) The knowledge and/or actions, or failure to act, of any director, manager, partner, officer, employee, agent or trustee of
the Company, any subsidiary of the Company, or any Enterprise shall not be imputed to Indemnitee for purposes of determining the right to indemnification under this Agreement. 

Section 12. Remedies of Indemnitee. 

(a) Subject to Section 12(f), in the event that (i) a determination is made pursuant to Section 10 of this Agreement that
Indemnitee is not entitled to indemnification under this Agreement, (ii) advancement of Expenses is not timely made pursuant to Section 8 of this Agreement, (iii) no determination of entitlement to indemnification shall have been made
pursuant to Section 10(a) of this Agreement within sixty (60) days after receipt by the Company of the request for indemnification for which a determination is to be made other than by Independent Counsel, (iv) payment of
indemnification or reimbursement of expenses is not made pursuant to Section 5 or 6 or the last sentence of Section 10(a) of this Agreement within thirty (30) days after receipt by the Company of a written request therefor (including
any invoices received by Indemnitee, which such invoices may be redacted as necessary to avoid the waiver of any privilege accorded by applicable law) or (v) payment of indemnification pursuant to Section 3 or 4 of this Agreement is not
made within thirty (30) days after a determination has been made that Indemnitee is entitled to indemnification, Indemnitee shall be entitled to an adjudication by the Delaware Court of his or her entitlement to such indemnification or
advancement. Alternatively, Indemnitee, at his or her option, may seek an award in arbitration to 

  
 8 

 
be conducted by a single arbitrator pursuant to the Commercial Arbitration Rules of the American Arbitration Association. Indemnitee shall commence such proceeding seeking an adjudication or an
award in arbitration within 180 days following the date on which Indemnitee first has the right to commence such proceeding pursuant to this Section 12(a); provided, however, that the foregoing time limitation shall not apply in
respect of a proceeding brought by Indemnitee to enforce his or her rights under Section 5 of this Agreement. The Company shall not oppose Indemnitee’s right to seek any such adjudication or award in arbitration. 

(b) In the event that a determination shall have been made pursuant to Section 10(a) of this Agreement that Indemnitee is not entitled to
indemnification, any judicial proceeding or arbitration commenced pursuant to this Section 12 shall be conducted in all respects as a de novo trial, or arbitration, on the merits and Indemnitee shall not be prejudiced by reason of that adverse
determination. In any judicial proceeding or arbitration commenced pursuant to this Section 12, the Company shall have the burden of proving Indemnitee is not entitled to indemnification or advancement, as the case may be. 

(c) If a determination shall have been made pursuant to Section 10(a) of this Agreement that Indemnitee is entitled to indemnification,
the Company shall be bound by such determination in any judicial proceeding or arbitration commenced pursuant to this Section 12, absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to
make Indemnitee’s statement not materially misleading, in connection with the request for indemnification, or (ii) a prohibition of such indemnification under applicable law. 

(d) The Company shall be precluded from asserting in any judicial proceeding or arbitration commenced pursuant to this Section 12 that the
procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court or before any such arbitrator that the Company is bound by all the provisions of this Agreement. 

(e) The Company shall indemnify Indemnitee to the fullest extent permitted by law against any and all Enforcement Expenses and, if requested by
Indemnitee, shall (within thirty (30) days after receipt by the Company of a written request therefor) advance, to the extent not prohibited by law, such Enforcement Expenses to Indemnitee, which are incurred by Indemnitee in connection with
any action brought by Indemnitee for indemnification or advancement from the Company under this Agreement or under any directors’ and officers’ liability insurance policies maintained by the Company in the suit for which indemnification or
advancement is being sought. Such written request for advancement shall include invoices received by Indemnitee in connection with such Enforcement Expenses but, in the case of invoices in connection with legal services, any references to legal work
performed or to expenditures made that would cause Indemnitee to waive any privilege accorded by applicable law need not be included with the invoice. 

(f) Notwithstanding anything in this Agreement to the contrary, no determination as to entitlement to indemnification under this Agreement
shall be required to be made prior to the final disposition of the Proceeding, including any appeal therein.

 Section 13. Non-exclusivity; Survival of
Rights; Insurance; Subrogation. 
 (a) The rights of indemnification and to receive advancement as provided by this Agreement shall not
be deemed exclusive of any other rights to which Indemnitee may at any time be entitled under applicable law, the Charter, the Bylaws, any agreement, a vote of stockholders or a resolution of directors, or otherwise. No amendment, alteration or
repeal of this Agreement or of any provision hereof shall limit or restrict any right of Indemnitee under this Agreement in respect of any action taken or omitted by such Indemnitee in his or her Corporate Status prior to such amendment, alteration
or repeal. To the extent that a change in Delaware law, whether by statute or judicial decision, permits greater indemnification or advancement than would be afforded currently under the Charter, Bylaws and this Agreement, it is the intent of the
parties hereto that Indemnitee shall enjoy by this Agreement the greater benefits so afforded by such change. No right or remedy herein conferred is intended to be exclusive of any other right or remedy, and every other right and remedy shall be
cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other right or remedy. 
 (b) To the extent that the Company maintains an insurance policy or policies
providing liability insurance for directors, managers, partners, officers, employees, agents or trustees of the Company or of any other Enterprise, Indemnitee shall be covered by such policy or policies in accordance with its or their terms to the
maximum extent of the coverage available for any such director, manager, partner, officer, employee, agent or trustee under such policy or policies. If, at the time of the receipt of a notice of a claim pursuant to the terms hereof, the Company has
director and officer liability insurance in effect, the Company shall give prompt notice of the commencement of such proceeding to the insurers in accordance with the procedures set forth in the respective policies. The Company shall thereafter take
all necessary or desirable action to cause such insurers to pay, on behalf of Indemnitee, all amounts payable as a result of such proceeding in accordance with the terms of such policies. 

(c) In the event of any payment under this Agreement, the Company shall be subrogated to the extent of such payment to all of the rights of
recovery of Indemnitee, who shall execute all papers required and take all action necessary to secure such rights, including execution of such documents as are necessary to enable the Company to bring suit to enforce such rights. 

(d) The Company’s obligation to provide indemnification or advancement hereunder to Indemnitee who is or was serving at the request of the
Company as a director, manager, partner, officer, employee, agent or trustee of any other Enterprise shall be reduced by any amount Indemnitee has actually received as indemnification or advancement from such other Enterprise. 

Section 14. Duration of Agreement. This Agreement shall continue until and terminate upon the later of: (a) ten (10) years
after the date that Indemnitee shall have ceased to serve as [both a director and] an officer of the Company or (b) one (1) year after the final termination of any Proceeding, including any appeal, then pending in respect of which Indemnitee is
granted rights of indemnification or advancement hereunder and of any proceeding commenced by Indemnitee pursuant to Section 12 of this Agreement relating thereto. This 

  
 10 

 
Agreement shall be binding upon the Company and its successors and assigns and shall inure to the benefit of Indemnitee and his or her heirs, executors and administrators. The Company shall
require and cause any successor (whether direct or indirect by purchase, merger, consolidation or otherwise) to all, substantially all or a substantial part, of the business and/or assets of the Company, by written agreement in form and substance
satisfactory to Indemnitee, expressly to assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform if no such succession had taken place. 

Section 15. Severability. If any provision or provisions of this Agreement shall be held to be invalid, illegal or unenforceable
for any reason whatsoever: (a) the validity, legality and enforceability of the remaining provisions of this Agreement (including, without limitation, each portion of any section of this Agreement containing any such provision held to be
invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby and shall remain enforceable to the fullest extent permitted by law; (b) such provision or provisions
shall be deemed reformed to the extent necessary to conform to applicable law and to give the maximum effect to the intent of the parties hereto; and (c) to the fullest extent possible, the provisions of this Agreement (including, without
limitation, each portion of any section of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall be construed so as to give effect to the intent
manifested thereby. 
 Section 16. Enforcement. 

(a) The Company expressly confirms and agrees that it has entered into this Agreement and assumed the obligations imposed on it hereby in order
to induce Indemnitee to serve or continue to serve as [a director and] an officer of the Company, and the Company acknowledges that Indemnitee is relying upon this Agreement in serving as [a director and] an officer of the Company. 

(b) This Agreement constitutes the entire agreement between the parties hereto with respect to the subject matter hereof and supersedes all
prior agreements and understandings, oral, written and implied, between the parties hereto with respect to the subject matter hereof; provided, however, that this Agreement is a supplement to and in furtherance of the Charter, the
Bylaws and applicable law, and shall not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder.

as a service provider of the Company. The parties intend that this Agreement be interpreted and construed with such intent.

 Exhibit 10.7 

EMPLOYMENT AGREEMENT 

This Employment Agreement (“Agreement”) is made by and between C4 Therapeutics (the “Company”), and (the
“Executive”), and is effective as of this __ day of __________, 20__ (the “Effective Date”). 
 WHEREAS,
the Company and the Executive are parties to an offer letter, dated [     ], [     ](1) (the “Prior Agreement”); and 
 WHEREAS, effective as of the Effective
Date, the parties intend this Agreement to replace in all respects the Prior Agreement, as well as any other prior agreements between the Executive and the Company regarding the subject matter herein, including without limitation any offer letter,
employment agreement or severance agreement, except for the Restrictive Covenant Agreement (as modified herein) and the Equity Documents (as defined below). 

NOW, THEREFORE, in consideration of the mutual covenants and agreements herein contained and other good and valuable consideration, the
receipt and sufficiency of which is hereby acknowledged, the parties agree as follows: 
 1. Employment. 

(a) Term. The term of this Agreement shall commence on the Effective Date and continue until terminated in accordance
with the provisions hereof (the “Term”). The Executive’s employment with the Company will continue to be “at will,” meaning that the Executive’s employment may be terminated by the Company or the Executive at any
time and for any reason subject to the terms of this Agreement. 
 (b) Position and Duties. During the Term, the
Executive shall serve as the [title] of the Company, and shall have powers and duties that may from time to time be prescribed by the Chief Executive Officer of the Company (the “CEO”) or another authorized executive,
provided that such duties are consistent with the Executive’s position or other positions that the Executive may hold from time to time. The Executive shall devote the Executive’s full working time and efforts to the business and
affairs of the Company. Notwithstanding the foregoing, the Executive may serve on other boards of directors, with the prior written approval of the Board of Directors of the Company (the “Board”), or engage in religious, charitable
or other community activities as long as such services and activities are disclosed to the Board and do not materially interfere with the Executive’s performance of the Executive’s duties to the Company as provided in this Agreement. 

2. Compensation and Related Matters. 

(a) Base Salary. During the Term, the Executive’s initial base salary rate shall be
$[         ] per annum. The Executive’s base salary may be increased by the Board or the Compensation Committee, provided that the Company may decrease the base salary by no more than 15% solely in
connection with an across-the-board salary reduction that is based on the Company’s financial performance and similarly affects all or substantially all senior
management employees of the Company. The Executive’s base salary in effect at any given time is referred to herein as “Base Salary.” The Base Salary shall be payable in a manner that is consistent with the Company’s usual
payroll practices for senior executives. 
 (b) Incentive Compensation. During the Term, the Executive shall be
eligible to receive cash incentive compensation as determined by the Board or the Compensation Committee in its discretion. The Executive’s target annual incentive compensation shall be [     ] percent
([     ]%) of the Executive’s Base Salary, as such percentage may be increased from time to time (the “Target Incentive Compensation”), provided that the Company may decrease by no more than 15% in
connection with an across-the-board target incentive compensation percentage reduction that is based on the Company’s financial performance and similarly affects
all or substantially all senior management employees of the Company. The actual amount of the Executive’s annual incentive compensation for any year, if any, shall be determined in the 

 

	(1) 	 NTD: To be updated for each executive; whereas clauses to be removed if there is no Prior Agreement.

 
sole discretion of the Board or the Compensation Committee, subject to the terms of any applicable incentive compensation plan that may be in effect from time to time. Annual incentive
compensation shall be paid to the Executive no later than March 15 of the year following the year in which it is earned. To earn any annual incentive compensation, the Executive must be employed by the Company for the entire preceding calendar
year. If this Agreement is entered into in connection with the commencement of the Executive’s employment with the Company, the Executive’s Target Incentive Compensation, if any, for such year shall be prorated depending on when in the
year the Executive first date of employment with the Company occurs. 
 (c) Expenses. The Executive shall be entitled
to receive prompt reimbursement for all reasonable expenses incurred by the Executive during the Term in performing services hereunder, in accordance with and subject to the policies and procedures then in effect and established by the Company for
its executive officers. 
 (d) Other Benefits. During the Term, the Executive shall be eligible to participate in or
receive benefits under the Company’s employee benefit plans in effect from time to time on a basis no less favorable than other senior management employees of the Company, subject to the terms and conditions of such plans. 

(e) Vacations. The Executive shall be eligible for vacation time in accordance with, and subject to, the Company’s
vacation policy as in effect from time to time. The Executive shall also be entitled to all paid holidays given by the Company to its executives. 

(f) Equity. The equity awards held by the Executive shall be governed by the terms and conditions of the Company’s
applicable equity incentive plan(s) and the applicable award agreement(s) governing the terms of such equity awards held by the Executive (collectively, the “Equity Documents”); provided, however, and notwithstanding
anything to the contrary in the Equity Documents, Section 5(a)(ii) of this Agreement shall apply in the event of a termination by the Company without Cause or by the Executive for Good Reason, in either event within the Change in Control Period
(as such terms are defined below). 
 3. Termination. During the Term, the Executive’s employment hereunder may be terminated
without any breach of this Agreement under the following circumstances: 
 (a) Death. The Executive’s employment
hereunder shall terminate upon the Executive’s death. 
 (b) Disability. The Company may terminate the
Executive’s employment if the Executive is disabled and unable to perform or expected to be able to perform the essential functions of the Executive’s then existing position or positions under this Agreement with or without reasonable
accommodation for a period of 180 days (which need not be consecutive) in any 12-month period. If any question shall arise as to whether, during any period, the Executive is disabled so as to be unable to
perform the essential functions of the Executive’s then existing position or positions with or without reasonable accommodation, the Executive may, and at the request of the Company shall, submit to the Company a certification in reasonable
detail by a physician selected by the Company to whom the Executive or the Executive’s guardian has no reasonable objection as to whether the Executive is so disabled or how long such disability is expected to continue, and such certification
shall, for the purposes of this Agreement, be deemed to be conclusive of the issue. The Executive shall cooperate with any reasonable request of the physician in connection with such certification. Nothing in this Section 3(b) shall be
construed to waive the Executive’s rights, if any, under existing law including, without limitation, the Family and Medical Leave Act of 1993, 29 U.S.C. §2601 et seq. and the Americans with Disabilities Act, 42 U.S.C. §12101
et seq. 
 (c) Termination by Company for Cause. The Company may terminate the Executive’s employment
hereunder for Cause. For purposes of this Agreement, “Cause” shall mean: (i) conduct by the Executive constituting a material act of misconduct in connection with the performance of the Executive’s duties, including,
without limitation, misappropriation of funds or property of the Company or any of its 

  
 2 

 
subsidiaries or affiliates other than the occasional, customary and de minimis use of Company property for personal purposes; (ii) the commission by the Executive of any felony or a
misdemeanor involving moral turpitude, deceit, dishonesty or fraud, or any conduct by the Executive that would reasonably be expected to result in material economic injury or material reputational harm to the Company or any of its subsidiaries and
affiliates if the Executive were retained in the Executive’s position; (iii) willful and intentional continued non-performance by the Executive of the Executive’s duties hereunder (other than by
reason of the Executive’s physical or mental illness, incapacity or disability) that has continued for more than 30 days following written notice from the Board of such willful and intentional continued
non-performance from the Board or the CEO, as applicable; (iv) a material breach by the Executive of any of the provisions contained in Section 7 of this Agreement or of the Restrictive Covenants
Agreement; (v) a material violation by the Executive of the Company’s written employment or corporate governance policies; or (vi) the failure to reasonably cooperate with a bona fide internal investigation or an investigation by
regulatory or law enforcement authorities after being instructed by the Company to cooperate, or the willful destruction or failure to preserve documents or other materials known to be relevant to such investigation or the inducement of others to
fail to cooperate or to produce documents or other materials in connection with such investigation. 
 (d) Termination
Without Cause. The Company may terminate the Executive’s employment hereunder at any time without Cause. Any termination by the Company of the Executive’s employment under this Agreement that does not constitute a termination for Cause
under Section 3(c) and does not result from the death or disability of the Executive under Section 3(a) or (b) shall be deemed a termination without Cause. 

(e) Termination by the Executive. The Executive may terminate the Executive’s employment hereunder at any time for
any reason, including but not limited to Good Reason. For purposes of this Agreement, “Good Reason” shall mean that the Executive has complied with the “Good Reason Process” (hereinafter defined) following the
occurrence of any of the following events without the Executive’s consent: (i) a material diminution in the Executive’s responsibilities, authority or duties; (ii) a diminution in the Executive’s Base Salary, except for across-the-board salary and/or target incentive compensation percentage reductions of no more than 15% that, in either case, are based on the Company’s financial
performance and similarly affect all or substantially all senior management employees of the Company; (iii) a requirement that the Executive work primarily from an office that is more than 30 miles from the office that the Executive primarily
provides services to the Company; or (iv) the material breach of this Agreement by the Company. “Good Reason Process” shall mean that (i) the Executive reasonably determines in good faith that a Good Reason condition has
occurred; (ii) the Executive notifies the Company in writing of the first occurrence of the Good Reason condition within 90 days of the date on which the Executive first became aware of such condition; (iii) the Executive cooperates in
good faith with the Company’s efforts, for a period not less than 30 days following such notice (the “Cure Period”), to remedy the condition; (iv) notwithstanding such efforts, the Good Reason condition continues to exist;
and (v) the Executive terminates the Executive’s employment within 60 days after the end of the Cure Period. If the Company cures the Good Reason condition during the Cure Period, Good Reason shall be deemed not to have occurred. 

(f) Notice of Termination. Except for termination as specified in Section 3(a), any termination of the
Executive’s employment by the Company or any such termination by the Executive shall be communicated by written Notice of Termination to the other party hereto. For purposes of this Agreement, a “Notice of Termination” shall
mean a notice that shall indicate the specific termination provision in this Agreement being relied upon. 
 (g) Date of
Termination. “Date of Termination” shall mean: (i) if the Executive’s employment is terminated by the Executive’s death, the date of the Executive’s death; (ii) if the Executive’s employment is
terminated on account of disability under Section 3(b) or by the Company for Cause under Section 3(c), the date on which Notice of Termination is given; (iii) if the Executive’s employment is terminated by the Company under
Section 3(d), the date on which a Notice of Termination is given unless another date is specified by the Company; (iv) if the Executive’s employment is terminated by the Executive under Section 3(e) other than for Good Reason, 30
days after the date on which a Notice of 

  
 3 

 
Termination is given; and (v) if the Executive’s employment is terminated by the Executive under Section 3(e) for Good Reason, the date on which a Notice of Termination is given
after the end of the Cure Period. Notwithstanding the foregoing, if the Executive gives a Notice of Termination to the Company, the Company may unilaterally accelerate the Date of Termination and such acceleration shall not result in a termination
by the Company for purposes of this Agreement. 
 (h) Resignations. To the extent applicable, the Executive shall be
deemed to have resigned from all officer and board member positions that the Executive holds with the Company or any of its subsidiaries or controlled affiliates upon the termination of the Executive’s employment for any reason. The Executive
shall execute any documents in reasonable form as may be reasonably requested by the Company to confirm or effectuate any such resignations. 

4. Compensation Upon Termination. 

(a) Termination Generally. If the Executive’s employment with the Company is terminated for any reason, the Company
shall pay or provide to the Executive (or to the Executive’s authorized representative or estate) (i) any Base Salary and Target Incentive Compensation earned through the Date of Termination, unpaid expense reimbursements (subject to, and
in accordance with, Section 2(c) of this Agreement); and (ii) any vested benefits the Executive may have under any employee benefit plan of the Company through the Date of Termination, which vested benefits shall be paid and/or provided in
accordance with the terms of such employee benefit plans (collectively, the “Accrued Benefit”). For the avoidance of doubt, the Executive’s right to indemnification by the Company and coverage under any applicable
directors’ and officers’ liability or other third-party insurance policy as provided herein shall continue following any such termination of employment. 

(b) Termination by the Company without Cause or by the Executive for Good Reason. During the Term, if the
Executive’s employment is terminated by the Company without Cause as provided in Section 3(d), or the Executive terminates the Executive’s employment for Good Reason as provided in Section 3(e), in either case outside of the
Change in Control Period, then the Company shall pay the Executive the Executive’s Accrued Benefit. In addition, subject to the Executive signing, not revoking and complying with a separation agreement in the form and manner provided by the
Company, containing, among other customary provisions, a reaffirmation of the Executive’s obligations under the Executive’s Restrictive Covenant Agreement, confidentiality of agreement, return of property, reasonable litigation cooperation
at the Company’s cost, mutual non-disparagement, a post-employment non-competition provision equal or less in duration than the Executive’s severance period,
and a seven (7) business day revocation period (the “Separation Agreement and Release”) and the Separation Agreement and Release becoming irrevocable, all within all within the time period required in the Separation
Agreement and Release but in no event later than 60 days after the Date of Termination: 
 (i) the Company shall pay the
Executive an amount equal to one times the Executive’s Base Salary (the “Severance Amount”). Notwithstanding the foregoing, if the Executive materially breaches any of the provisions contained in Section 7 of this
Agreement or in the Restrictive Covenant Agreement, all payments of the Severance Amount may be terminated by the Company without affecting the other provisions of the Separation Agreement and Release. In addition, the Company may in its sole
discretion, and subject to receipt of the recommendation of the Compensation Committee and approval by the Board, pay the Executive a pro rata portion of the Executive’s incentive compensation at such time as the Company determines but in any
event no later than March 15 of the year following the year in which the Executive’s employment ends; 
 (ii)
subject to the Executive’s copayment of premium amounts at the applicable active employees’ rate and the Executive’s proper election to receive benefits under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended
(“COBRA”), the Company shall pay to the group health plan provider, the COBRA provider or the Executive a monthly payment equal to the monthly employer contribution that the Company would have made to provide health insurance to the
Executive if the Executive had remained employed by the Company until the earliest: (i) the twelve-month anniversary of the Date of Termination; (ii) the Executive’s eligibility for group health coverage through other

  
 4 

 
employment; or (iii) the end of the Executive’s eligibility under COBRA for continuation coverage for health care. Notwithstanding the foregoing, if the Company determines at any time
that its payments pursuant to this paragraph may be taxable income to the Executive, it may convert such payments to payroll payments directly to the Executive on the Company’s regular payroll dates, which shall be subject to tax-related deductions and withholdings; and 
 (iii) The amounts payable under
Section 4(b), to the extent taxable, shall be paid out in substantially equal installments in accordance with the Company’s payroll practice over twelve months commencing within 60 days after the Date of Termination;
provided, however, that if the 60-day period begins in one calendar year and ends in a second calendar year, the Severance Amount, to the extent it qualifies as
“non-qualified deferred compensation” within the meaning of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), shall begin to be paid in the second
calendar year by the last day of such 60-day period; provided, further, that the initial payment shall include a catch-up payment to cover amounts
retroactive to the day immediately following the Date of Termination. Each payment pursuant to this Agreement is intended to constitute a separate payment for purposes of Treasury Regulation
Section 1.409A-2(b)(2)). 
 5. Change in Control Payment. The provisions of this
Section 5 set forth certain terms of an agreement reached between the Executive and the Company regarding the Executive’s rights and obligations upon the occurrence of a Change in Control of the Company. These provisions are intended to
assure and encourage in advance the Executive’s continued attention and dedication to the Executive’s assigned duties and the Executive’s objectivity during the pendency and after the occurrence of any such event. These provisions
shall apply in lieu of, and expressly supersede, the provisions of Section 4(b) regarding severance pay and benefits upon a termination of employment by the Company without Cause or by the Executive for Good Reason, if such termination of
employment occurs upon, immediately prior to, in connection with or within 12 months after the occurrence of the first event constituting a Change in Control (such period, the “Change in Control Period”). These provisions shall
terminate and be of no further force or effect beginning 12 months after the consummation of a Change in Control. 
 (a)
Change in Control. If during the Change in Control Period the Executive’s employment is terminated by the Company without Cause as provided in Section 3(d) or the Executive terminates the Executive’s employment for Good Reason
as provided in Section 3(e), then, in addition to paying the Executive the Accrued Benefit, and subject to the signing, non-revocation and compliance with the Separation Agreement and Release by the
Executive and the Separation Agreement and Release becoming irrevocable, all within the time period required in the Separation Agreement and Release but in no event later than 60 days after the Date of Termination: 

(i) the Company shall pay the Executive a lump sum in cash in an amount equal to one times the sum of (A) the
Executive’s then current Base Salary (or the Executive’s Base Salary in effect immediately prior to the Change in Control, if higher) plus (B) the Executive’s Target Incentive Compensation (or the Executive’s Target
Incentive Compensation in effect immediately prior to the Change in Control, if higher) (the “Change in Control Payment”); and 

(ii) notwithstanding anything to the contrary in any applicable option agreement or other stock-based award agreement or the
Company’s equity plan, all stock options and other stock-based awards held by the Executive (collectively, the “Equity Awards”) shall immediately accelerate and become fully exercisable or nonforfeitable (with any Equity Awards
subject to performance-based vesting conditions becoming vested based on the attainment of the greater of (A) target level performance or (B) actual performance as of the Date of Termination) as of the Accelerated Vesting Date; provided
that any termination or forfeiture of the unvested portion of such Equity Awards that would otherwise occur on the Date of Termination in the absence of this Agreement under any applicable option agreement, other stock-based award agreement or the
Company’s equity plan will be delayed until the effective date of the Separation Agreement and Release and will only occur if the vesting pursuant to this subsection does not occur due to the absence of the Separation Agreement and Release
becoming fully effective within the time period set forth therein. Notwithstanding the foregoing, (i) no additional vesting of the Equity Awards shall occur during the period between the Executive’s Date of Termination and the Accelerated
Vesting Date and (ii) to the extent the parties to a Sale Event (as defined in the Equity Documents) do not provide 

  
 5 

 
for the assumption, continuation or substitution of Equity Awards, upon the effective time of the Sale Event, such Equity Awards shall immediately accelerate and become fully exercisable or
nonforfeitable (with any Equity Awards subject to performance-based vesting conditions becoming vested based on the attainment of the greater of (A) target level performance or (B) actual performance as of the date of the Sale Event); and

 (iii) subject to the Executive’s copayment of premium amounts at the applicable active employees’ rate and the
Executive’s proper election to receive benefits under COBRA, the Company shall pay to the group health plan provider, the COBRA provider or the Executive a monthly payment equal to the monthly employer contribution that the Company would have
made to provide health insurance to the Executive if the Executive had remained employed by the Company until the earliest: (i) the 12-month anniversary of the Date of Termination; (ii) the
Executive’s eligibility for group health coverage through other employment; or (iii) the end of the Executive’s eligibility under COBRA for continuation coverage for health care. Notwithstanding the foregoing, if the Company
determines at any time that its payments pursuant to this paragraph may be taxable income to the Executive, it may convert such payments to payroll payments directly to the Executive on the Company’s regular payroll dates, which shall be
subject to tax-related deductions and withholdings. 
 (iv) The amounts payable under
this Section 5(a), to the extent taxable, shall be paid or commence to be paid within 60 days after the Date of Termination; provided, however, that if the 60-day period begins in one calendar year and
ends in a second calendar year, such payments to the extent they qualify as “non-qualified deferred compensation” within the meaning of Section 409A of the Code, shall be paid or commence to be
paid in the second calendar year by the last day of such 60-day period. 
 (b)
Additional Limitation. 
 (i) Notwithstanding anything in this Agreement to the contrary, if the amount of any
compensation, payment or distribution by the Company to or for the benefit of the Executive, whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise, calculated in a manner consistent with
Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”) and the applicable regulations thereunder (the “Aggregate Payments”), would be subject to the excise tax imposed by Section 4999
of the Code, then the Aggregate Payments shall be reduced (but not below zero) so that the sum of all of the Aggregate Payments shall be $1.00 less than the amount at which the Executive becomes subject to the excise tax imposed by Section 4999
of the Code; provided that such reduction shall only occur if it would result in the Executive receiving a higher After Tax Amount (as defined below) than the Executive would receive if the Aggregate Payments were not subject to such reduction. In
such event, the Aggregate Payments shall be reduced in the following order, in each case, in reverse chronological order beginning with the Aggregate Payments that are to be paid the furthest in time from consummation of the transaction that is
subject to Section 280G of the Code: (1) cash payments not subject to Section 409A of the Code; (2) cash payments subject to Section 409A of the Code; (3) equity-based payments and acceleration; and (4) non-cash forms of benefits; provided that in the case of all the foregoing Aggregate Payments all amounts or payments that are not subject to calculation under Treas. Reg.
§1.280G-1, Q&A-24(b) or (c) shall be reduced before any amounts that are subject to calculation under Treas. Reg.
§1.280G-1, Q&A-24(b) or (c). 
 (ii)
For purposes of this Section 5(b), the “After Tax Amount” means the amount of the Aggregate Payments less all federal, state, and local income, excise and employment taxes imposed on the Executive as a result of the
Executive’s receipt of the Aggregate Payments. For purposes of determining the After Tax Amount, the Executive shall be deemed to pay federal income taxes at the highest marginal rate of federal income taxation applicable to individuals for the
calendar year in which the determination is to be made, and state and local income taxes at the highest marginal rates of individual taxation in each applicable state and locality, net of the maximum reduction in federal income taxes that could be
obtained from deduction of such state and local taxes. 

  
 6 

 (iii) The determination as to whether a reduction in the Aggregate Payments
shall be made pursuant to Section 5(b)(i) shall be made by a nationally recognized accounting firm selected by the Company (the “Accounting Firm”), which shall provide detailed supporting calculations both to the Company and
the Executive within 15 business days of the Date of Termination, if applicable, or at such earlier time as is reasonably requested by the Company or the Executive. Any determination by the Accounting Firm shall be binding upon the Company and the
Executive, absent manifest error or omission. The costs of obtaining such determination and all related fees and expenses (including related fees and expenses incurred in any later audit) shall be borne by the Company. 

(c) Definitions. For purposes of this Section 5, the term “Change in Control” shall have the
following meaning: 
 (i) any “person,” as such term is used in Sections 13(d) and 14(d) of the Securities Exchange
Act of 1934, as amended (the “Act”) (other than the Company, any of its subsidiaries, or any trustee, fiduciary or other person or entity holding securities under any employee benefit plan or trust of the Company or any of its
subsidiaries), together with all “affiliates” and “associates” (as such terms are defined in Rule 12b-2 under the Act) of such person, shall become the “beneficial owner” (as such
term is defined in Rule 13d-3 under the Act), directly or indirectly, of securities of the Company representing fifty percent (50%) or more of the combined voting power of the Company’s then outstanding
securities having the right to vote in an election of the Board (“Voting Securities”) (in such case other than as a result of an acquisition of securities directly from the Company); or 

(ii) the date on which a majority of the members of the Board is replaced during any
12-month period by directors whose appointment or election is not endorsed by a majority of the members of the Board before the date of the appointment or election; or 

(iii) the consummation of (A) any consolidation or merger of the Company where the stockholders of the Company,
immediately prior to the consolidation or merger, would not, immediately after the consolidation or merger, beneficially own (as such term is defined in Rule 13d-3 under the Act), directly or indirectly,
shares representing in the aggregate more than fifty percent (50%) of the voting shares of the Company issuing cash or securities in the consolidation or merger (or of its ultimate parent corporation, if any), or (B) any sale or other transfer
(in one transaction or a series of transactions contemplated or arranged by any party as a single plan) of all or substantially all of the assets of the Company. 

Notwithstanding the foregoing, a Change in Control shall not be deemed to have occurred for purposes of the foregoing clause (i) solely as
the result of an acquisition of securities by the Company that, by reducing the number of shares of Voting Securities outstanding, increases the proportionate number of Voting Securities beneficially owned by any person to fifty percent (50%) or
more of the combined voting power of all of the then outstanding Voting Securities; provided, however, that if any person referred to in this sentence shall thereafter become the beneficial owner of any additional shares of Voting
Securities (other than pursuant to a stock split, stock dividend, or similar transaction or as a result of an acquisition of securities directly from the Company) and immediately thereafter beneficially owns fifty percent (50%) or more of the
combined voting power of all of the then outstanding Voting Securities, then a Change in Control shall be deemed to have occurred for purposes of the foregoing clause (i). 

6. Section 409A. 

(a) Notwithstanding anything in this Agreement to the contrary, if at the time of the Executive’s separation from service
within the meaning of Section 409A of the Code, the Company determines that the Executive is a “specified employee” within the meaning of Section 409A(a)(2)(B)(i) of the Code, then to the extent any payment or benefit that the
Executive becomes entitled to under this Agreement on account of the Executive’s separation from service would be considered deferred compensation otherwise subject to the twenty percent (20%) additional tax imposed pursuant to
Section 409A(a) of the Code as a result of the application of Section 409A(a)(2)(B)(i) of the Code, such payment shall not be payable and such benefit shall not be provided until the date that is the earlier of (A) six months and one
day after the Executive’s separation from service, or (B) the Executive’s death. If any such delayed cash payment is otherwise payable on an installment basis, the first payment shall include a catch-up payment covering amounts that
would otherwise have been paid during the six-month period but for the application of this provision, and the balance of the installments shall be payable in accordance with their original schedule. 

  
 7 

 (b) All in-kind benefits provided
and expenses eligible for reimbursement under this Agreement shall be provided by the Company or incurred by the Executive during the time periods set forth in this Agreement. All reimbursements shall be paid as soon as administratively practicable,
but in no event shall any reimbursement be paid after the last day of the taxable year following the taxable year in which the expense was incurred. The amount of in-kind benefits provided or reimbursable
expenses incurred in one taxable year shall not affect the in-kind benefits to be provided or the expenses eligible for reimbursement in any other taxable year (except for any lifetime or other aggregate
limitation applicable to medical expenses). This right to reimbursement or in-kind benefits is not subject to liquidation or exchange for another benefit. 

(c) To the extent that any payment or benefit described in this Agreement constitutes “nonqualified deferred
compensation” under Section 409A of the Code, and to the extent that such payment or benefit is payable upon the Executive’s termination of employment, then such payments or benefits shall be payable only upon the Executive’s
“separation from service.” The determination of whether and when a separation from service has occurred shall be made in accordance with the presumptions set forth in Treasury Regulation Section 1.409A1(h). Notwithstanding anything in
this Agreement to the contrary, to the extent any payment that the Executive becomes entitled to under Section 5(a)(i) constitutes “non-qualified deferred compensation” under Section 409A
of the Code and is not otherwise exempt from Section 409A of the Code, the definition of “Change in Control” for purposes of such payment must also constitute a “change in control event,” as defined in Treasury Regulation Section 1.409A-3(i)(5). 
 (d) The parties intend that this Agreement will be
administered in accordance with Section 409A of the Code. To the extent that any provision of this Agreement is ambiguous as to its compliance with Section 409A of the Code, the provision shall be read in such a manner so that all payments
hereunder comply with Section 409A of the Code. Each payment pursuant to this Agreement is intended to constitute a separate payment for purposes of Treasury Regulation Section 1.409A2(b)(2). The parties agree that this Agreement may be
amended, as reasonably requested by either party, and as may be necessary to fully comply with Section 409A of the Code and all related rules and regulations in order to preserve the payments and benefits provided hereunder without additional
cost to either party. 
 (e) The Company makes no representation or warranty and shall have no liability to the Executive or
any other person if any provisions of this Agreement are determined to constitute deferred compensation subject to Section 409A of the Code but do not satisfy an exemption from, or the conditions of, such Section. 

7. Confidential Information, Non-competition and Cooperation. 

(a) [The terms of the [NAME OF RESTRICTIVE COVENANTS AGREEMENT], dated [______________] (the “Restrictive Covenants
Agreement”), between the Company and the Executive, attached hereto as Exhibit A, continue to be in full force and effect.][OR][As a condition of employment, the Executive is required to enter into the [NAME OF RESTRICTIVE
COVENANTS AGREEMENT], attached hereto as Exhibit A (the “Restrictive Covenants Agreement”). [The Executive acknowledges and agrees that the Executive received the Restrictive Covenants Agreement with this Agreement and at
least ten (10) business days before the commencement of the Executive’s employment.]2 For purposes of this Agreement, the obligations in this Section 7, those that arise in the
Restrictive Covenants Agreement, the post-employment non-competition obligation to be contained in any Separation Agreement and Release as may be entered into by and between the Company and Executive, and any
other agreement relating to confidentiality, assignment of inventions, or other restrictive covenants shall collectively be referred to as the “Continuing Obligations.” 

 
  

	2 	 NTD: For new Massachusetts-based executives.

 (b) Third-Party Agreements and Rights. The Executive hereby confirms
that the Executive is not bound by the terms of any agreement with any previous employer or other party that restricts in any way the Executive’s use or disclosure of information or the Executive’s engagement in any business in a manner
that would interfere with or inhibit the Executive’s ability to perform the Executive’s duties to the Company. The Executive represents to the Company that the Executive’s execution of this Agreement, the Executive’s employment
with the Company and the performance of the Executive’s proposed duties for the Company will not violate any obligations the Executive may have to any such previous employer or other party. In the Executive’s work for the Company, the
Executive will not disclose or make use of any information in violation of any agreements with or rights of any such previous employer or other party, and the Executive will not bring to the premises of the Company any copies or other tangible
embodiments of non-public information belonging to or obtained from any such previous employment or other party. 

(c) Litigation and Regulatory Cooperation. During and after the Executive’s employment, the Executive shall
reasonably cooperate with the Company in the defense or prosecution of any claims or actions now in existence or that may be brought in the future against or on behalf of the Company that relate to events or occurrences that transpired while the
Executive was employed by the Company. The Executive’s cooperation in connection with such claims or actions shall include, but not be limited to, being available to meet with counsel to prepare for discovery or trial and to act as a witness on
behalf of the Company at mutually convenient times. During and after the Executive’s employment, the Executive also shall reasonably cooperate with the Company in connection with any investigation or review of any federal, state or local
regulatory authority that relates to events or occurrences that transpired while the Executive was employed by the Company. The Company shall reimburse the Executive for any reasonable
out-of-pocket expenses incurred in connection with the Executive’s performance of obligations pursuant to this Section 7(c). 

(d) Relief. The Executive agrees that it would be difficult to measure any damages caused to the Company that might
result from any breach by the Executive of the Continuing Obligations and that, in any event, money damages would be an inadequate remedy for any such breach. Accordingly, the Executive agrees that if the Executive breaches, or proposes to
breach, any portion of the Continuing Obligations, the Company shall be entitled, in addition to all other remedies that it may have, to an injunction or other appropriate equitable relief to restrain any such breach without showing or proving any
actual damage to the Company. 
 (e) Protected Disclosures and Other Protected Actions. Nothing in this Agreement
shall be interpreted or applied to prohibit the Executive from making any good faith report to any governmental agency or other governmental entity (a “Government Agency”) concerning any act or omission that the Executive reasonably
believes constitutes a possible violation of federal or state law or making other disclosures that are protected under the anti-retaliation or whistleblower provisions of applicable federal or state law or regulation. In addition, nothing contained
in this Agreement limits the Executive’s ability to communicate with any Government Agency or otherwise participate in any investigation or proceeding that may be conducted by any Government Agency, including the Executive’s ability to
provide documents or other information, without notice to the Company. In addition, for the avoidance of doubt, pursuant to the federal Defend Trade Secrets Act of 2016, the Executive shall not be held criminally or civilly liable under any federal
or state trade secret law or under this Agreement or the Restrictive Covenant Agreement for the disclosure of a trade secret that (a) is made (i) in confidence to a federal, state, or local government official, either directly or
indirectly, or to an attorney; and (ii) solely for the purpose of reporting or investigating a suspected violation of law; or (b) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under
seal. 
 8. Arbitration of Disputes. 

(a) Arbitration Generally. Any controversy or claim arising out of or relating to this Agreement or the breach thereof
or otherwise arising out of the Executive’s employment or the termination of that employment (including, without limitation, any claims of unlawful employment discrimination or retaliation, whether based on race, religion, national origin, sex,
gender, age, disability, sexual orientation, or any other protected class under applicable law, including without limitation Massachusetts General Laws 

  
 9 

 
Chapter 151B) shall, to the fullest extent permitted by law, be settled by arbitration in any forum and form agreed upon by the parties or, in the absence of such an agreement, under the auspices
of JAMS in Boston, Massachusetts in accordance with the JAMS Employment Arbitration Rules, including, but not limited to, the rules and procedures applicable to the selection of arbitrators. The Executive understands that the Executive may only
bring such claims in the Executive’s individual capacity and not as a plaintiff or class member in any purported class proceeding or any purported representative proceeding. The Executive further understands that, by signing this Agreement, the
Company and the Executive are giving up any right they may have to a jury trial on all claims they may have against each other. Judgment upon the award rendered by the arbitrator may be entered in any court having jurisdiction thereof. This
Section 8 shall be specifically enforceable. Notwithstanding the foregoing, this Section 8 shall not preclude either party from pursuing a court action for the sole purpose of obtaining a temporary restraining order or a preliminary
injunction in circumstances in which such relief is appropriate, including without limitation relief sought under the Restrictive Covenants Agreement; provided that any other relief shall be pursued through an arbitration proceeding pursuant to this
Section 8. 
 (b) Arbitration Fees and Costs. The Executive shall be required to pay an arbitration fee to
initiate any arbitration equal to what the Executive would be charged as a first appearance fee in court. The Company shall advance the remaining fees and costs of the arbitrator. However, to the extent permissible under the law, and following the
arbitrator’s ruling on the matter, the arbitrator may rule that the arbitrator’s fees and costs be distributed in an alternative manner. Each party shall pay its own costs and attorneys’ fees, if any. If, however, any party prevails
on a statutory or contractual claim that affords the prevailing party attorneys’ fees (including pursuant to this Agreement), the arbitrator may award attorneys’ fees to the prevailing party to the extent permitted by law. 

9. Consent to Jurisdiction. To the extent that any court action is permitted consistent with or to enforce Section 8 of this
Agreement, the parties hereby consent to the jurisdiction of the Superior Court of the Commonwealth of Massachusetts and the United States District Court for the District of Massachusetts. Accordingly, with respect to any such court action, the
Executive (a) submits to the personal jurisdiction of such courts; (b) consents to service of process; and (c) waives any other requirement (whether imposed by statute, rule of court, or otherwise) with respect to personal
jurisdiction or service of process. 
 10. Indemnification. The Company and the Executive hereby agree to execute the Company’s
standard indemnification agreement for senior executives. 
 11. Integration. This Agreement constitutes the entire agreement between
the parties with respect to compensation, severance pay, benefits and accelerated vesting and supersedes in all respects all prior agreements between the parties concerning the subject matter hereof, including without limitation the Prior Agreement
and any severance agreements, provided that the Restrictive Covenant Agreement, the Equity Documents, any indemnification agreement, and any other agreement relating to confidentiality, non-competition, non-solicitation or assignment of inventions shall not be superseded by this Agreement and the Executive acknowledges and agrees that any such agreements remains in full force and effect. 

12. Withholding. All payments made by the Company to the Executive under this Agreement shall be net of any tax or other amounts
required to be withheld by the Company under applicable law. Nothing in this Agreement shall be construed to require the Company to make any payments to compensate the Executive for any adverse tax effect associated with any payments or benefits or
for any deduction or withholding from any payment or benefit. 
 13. Enforceability. If any portion or provision of this Agreement
(including, without limitation, any portion or provision of any section of this Agreement) shall to any extent be declared illegal or unenforceable by a court of competent jurisdiction, then the remainder of this Agreement, or the application of
such portion or provision in circumstances other than those as to which it is so declared illegal or unenforceable, shall not be affected thereby, and each portion and provision of this Agreement shall be valid and enforceable to the fullest extent
permitted by law. 

  
 10 

 14. Survival. The provisions of this Agreement shall survive the termination of this
Agreement and/or the termination of the Executive’s employment to the extent necessary to effectuate the terms contained herein. 
 15.
Waiver. No waiver of any provision hereof shall be effective unless made in writing and signed by the waiving party. The failure of any party to require the performance of any term or obligation of this Agreement, or the waiver by any party
of any breach of this Agreement, shall not prevent any subsequent enforcement of such term or obligation or be deemed a waiver of any subsequent breach. 

16. Notices. Any notices, requests, demands and other communications provided for by this Agreement shall be sufficient if in writing
and delivered in person or sent by a nationally recognized overnight courier service or by registered or certified mail, postage prepaid, return receipt requested, to the Executive at the last address the Executive has filed in writing with the
Company or, in the case of the Company, at its main offices, attention of the Board. 
 17. Amendment. This Agreement may be amended
or modified only by a written instrument signed by the Executive and by a duly authorized representative of the Company. 
 18. Effect on
Other Plans and Agreements. Nothing in this Agreement shall be construed to limit the rights of the Executive under the Company’s benefit plans, programs or policies except as otherwise provided in Section 7 hereof, and except that the
Executive shall have no rights to any severance benefits under any Company severance pay plan, offer letter or otherwise. In the event that the Executive is party to an agreement with the Company providing for payments or benefits under such
agreement and this Agreement, the terms of this Agreement shall govern and the Executive may receive payment under this Agreement only and not both. Further, Section 4 and Section 5 of this Agreement are mutually exclusive and in no event
shall the Executive be entitled to payments or benefits pursuant to Section 4 and Section 5 of this Agreement. 
 19. Governing
Law. This is a Massachusetts contract and shall be construed under and be governed in all respects by the laws of the Commonwealth of Massachusetts, without giving effect to the conflict of laws principles of such Commonwealth. With respect to
any disputes concerning federal law, such disputes shall be determined in accordance with the law as it would be interpreted and applied by the United States Court of Appeals for the First Circuit. 

20. Assignment. Neither the Executive nor the Company may make any assignment of this Agreement or any interest in it, by operation of
law or otherwise, without the prior written consent of the other; provided, however, that the Company may assign its rights and obligations under this Agreement (including the Restrictive Covenant Agreement) without the
Executive’s consent to any affiliate or to any person or entity with whom the Company shall hereafter effect a reorganization, consolidate with, or merge into or to whom it transfers all or substantially all of its properties or assets;
provided further that if the purchaser in any transaction involving the transfer of all or substantially all of the Company’s assets assumes this Agreement and the Executive accepts a position with the purchaser that is equivalent or
better to the Executive’s position immediately preceding such transaction, then the Executive shall not be entitled to any Severance Amount pursuant to Section 4 or any Change in Control Payment pursuant to Section 5. This Agreement
shall inure to the benefit of and be binding upon the Executive and the Company, and each of the Executive’s and the Company’s respective successors, executors, administrators, heirs and permitted assigns. 

21. Counterparts. This Agreement may be executed in any number of counterparts, each of which when so executed and delivered shall be
taken to be an original; but such counterparts shall together constitute one and the same document. 
 22. Gender Neutral. Wherever
used herein, a pronoun in the masculine gender shall be considered as including the feminine gender unless the context clearly indicates otherwise.
