INDEMNITY AGREEMENT 

THIS INDEMNITY AGREEMENT (this “Agreement”) is effective as of
[                    ], and is made by and between ADICET BIO, INC. a Delaware corporation (the “Company”), and
[                    ] (“Indemnitee”). 

RECITALS 

WHEREAS, Company desires to attract and retain the services of highly qualified individuals as directors, officers, employees and agents; 

WHEREAS, highly qualified persons have become more reluctant to serve corporations as directors or in other capacities unless they are
provided with adequate protection through insurance or adequate indemnification against inordinate risks of claims and actions against them arising out of their service to and activities on behalf of the corporation; 

WHEREAS, the Company’s Amended and Restated Certificate of Incorporation (the “Certificate of Incorporation”) and
Amended and Restated Bylaws (the “Bylaws”) require that the Company indemnify its directors, and empowers the Company to indemnify its officers, employees and agents, as authorized by the Delaware General Corporation
Law, as amended (the “DGCL”), under which the Company is organized, and the Certificate of Incorporation and such Bylaws expressly provide that the indemnification provided therein is not exclusive and contemplates that the
Company may enter into separate agreements with its directors, officers and other persons to set forth specific indemnification provisions; 

WHEREAS, the Indemnitee does not regard the protection currently provided by applicable law, the Company’s governing documents and
available insurance as adequate under the present circumstances, and the Company has determined that Indemnitee and other directors, officers, employees and agents of the Company may not be willing to serve or continue to serve in such capacities
without additional protection; 
 WHEREAS, this Agreement is a supplement to and in furtherance of the Certificate of Incorporation and 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; and 

WHEREAS, it is reasonable, prudent and necessary 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 so that they will serve or continue to serve the Company free from undue concern that they will not be so indemnified; 

WHEREAS, the Company desires and has requested Indemnitee to serve as a director, officer, employee or agent of the Company, as the case may
be, and has proffered this Agreement to Indemnitee as an additional inducement to serve in such capacity; and 
 WHEREAS, the Indemnitee is
willing to serve, or to continue to serve, as a director, officer, employee or agent of the Company, as the case may be, if Indemnitee is furnished the indemnity provided for herein by the Company.

compensation for time spent by Indemnitee for which he or she is not compensated by the Company or any subsidiary or third party (x) for any period during which Indemnitee is not an agent, in the employment of, or providing services for
compensation to, the Company or any subsidiary; and (y) if the rate of compensation and estimated time involved is approved by the directors of the Company who are not parties to any action with respect to which expenses are incurred, for

 2. 













 
“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. 

(f)    “Proceeding” means 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 or investigative nature, and whether formal or informal in any case, in which Indemnitee was, is or will be involved as a party or participant (including as a witness) or otherwise by reason of: (i) the fact that Indemnitee is or
was a director or agent of the Company; (ii) any action taken by Indemnitee or any action on Indemnitee’s part while acting as director or agent of the Company; or (iii) the fact that Indemnitee is or was serving at the request of the

trust, employee benefit plan or other enterprise of which Indemnitee is or was serving at the request of the Company as a director, officer, employee, agent or fiduciary. 

(h)    Indemnification to the Fullest Extent. For purposes of this Agreement, the meaning of the phrase
“to the fullest extent authorized or permitted by law” shall include, but not be limited to: (i) to the fullest extent authorized or permitted by the provision of the DGCL that authorizes or contemplates additional indemnification by
agreement, or the corresponding provision of any amendment to or replacement of the DGCL or such provision thereof; and (ii) to the fullest extent authorized or permitted by any amendments to or replacements of the DGCL adopted after the date
of this Agreement that increase the extent to which a corporation may indemnify its directors and officers. 

2.    Agreement to Serve. Indemnitee will serve as a director and/or agent of the Company faithfully and at
the will of the Company, so long as Indemnitee is duly appointed or elected and qualified in accordance with the applicable provisions of the Bylaws or other applicable charter documents of the Company, or until such time as Indemnitee tenders
Indemnitee’s resignation in writing; provided, however, that nothing contained in this Agreement is intended as an employment agreement between Indemnitee and the Company or any of its subsidiaries or to create any right to continued employment
of Indemnitee with the Company or any of its subsidiaries in any capacity. 
 The Company acknowledges that it has entered into this
Agreement and assumes the obligations imposed on it hereby, in addition to and separate from its obligations to Indemnitee under the Bylaws, to induce Indemnitee to serve as a director and/or agent of the Company, and the Company acknowledges that
Indemnitee is relying upon this Agreement in serving as a director and/or agent of the Company. 

  
 3. 













 3.    Indemnification and Contribution. 

(a)    Indemnification. The Company hereby agrees to hold harmless and indemnify Indemnitee to the fullest
extent permitted by law, including the DGCL, as the same may be amended from time to time (but, only to the extent that such amendment permits Indemnitee to broader indemnification rights than the DGCL permitted prior to adoption of such amendment).

 (b)    Proceedings Other Than Proceedings by or in the Right of the Company. Indemnitee shall be
entitled to the rights of indemnification provided in this Section 3(a) if, by reason of Indemnitee’s Corporate Status, the Indemnitee is, or is threatened to be made, a party to or participant in any Proceeding other than a Proceeding by
or in the right of the Company. Pursuant to this Section 3(b), Indemnitee shall be indemnified against all Expenses, judgments, penalties, fines and amounts paid in settlement actually incurred by or on behalf of such Indemnitee in connection
with such Proceeding or any claim, issue or matter therein, if the Indemnitee acted in good faith and in a manner the Indemnitee reasonably believed to be in or not opposed to the best interests of the Company, and with respect to any criminal
Proceeding, had no reasonable cause to believe the Indemnitee’s conduct was unlawful. 

(c)    Indemnification in Derivative Actions and Direct Actions by the Company. The Company shall indemnify
Indemnitee to the fullest extent authorized or permitted by law, including the DGCL, as the same may be amended from time to time (but, only to the extent that such amendment permits Indemnitee to broader indemnification rights than the DGCL
permitted prior to adoption of such amendment), if, by reason of Indemnitee’s Corporate Status, the Indemnitee is, or is threatened to be made, a party to or participant in any Proceeding brought by or in the right of the Company. Pursuant to
this Section 3(c), Indemnitee shall be indemnified against all Expenses, judgments, penalties, fines and amounts paid in settlement actually incurred by or on behalf of such Indemnitee in connection with such Proceeding if the Indemnitee acted
in good faith and in a manner the Indemnitee reasonably believed to be in or not opposed to the best interests of the Company; provided, however, if applicable law so provides, no indemnification against such Expenses shall be made in respect of any
claim, issue or matter in such Proceeding as to which Indemnitee shall have been adjudged to be liable to the Company unless and to the extent that the Court of Chancery of the State of Delaware shall determine that such indemnification may be made.

 (d)    Indemnification of Related Parties. If (i) Indemnitee is or was affiliated with one or more
venture capital funds that has invested in the Company (an “Appointing Stockholder”), and (ii) the Appointing Stockholder is, or is threatened to be made, a party to or a participant in any Proceeding, and (iii) the
Appointing Stockholder’s involvement in the Proceeding arises primarily out of, or relates to, any claim based on the Indemnitee’s service to the Company as a director or other fiduciary of the Company, the Appointing Stockholder shall be
entitled to all of the indemnification rights and remedies under this Agreement pursuant to this Agreement (and subject to the same limitations thereon) as if the Appointing Stockholder were the Indemnitee and advancement of expenses shall apply to
any such indemnification of Appointing Stockholder. 

  
 4. 













 (e)    Fund Indemnitors. The Company hereby acknowledges
that the Indemnitee has or may have in the future certain rights to indemnification, advancement of expenses and/or insurance provided by entities and/or organizations other than the Company (collectively, the “Fund
Indemnitors”). In the event that the Indemnitee is, or is threatened to be made, a party to or a participant in any proceeding to the extent resulting from any claim based on the Indemnitee’s service to the Company as a director or
other fiduciary of the Company, then the Company shall (i) be an indemnitor of first resort (i.e., its obligations to Indemnitee are primary and any obligation of the Fund Indemnitors to advance expenses or to provide indemnification for
the same expenses or liabilities incurred by Indemnitee are secondary), (ii) be required to advance reasonable expenses incurred by Indemnitee, and (iii) be liable for the full amount of all Expenses, judgments, penalties, fines and amounts
paid in settlement to the extent legally permitted and as required by the terms of this Agreement and any provision of the Bylaws or the Certificate of Incorporation (or any other agreement between the Company and Indemnitee), without regard to any
rights Indemnitee may have against the Fund Indemnitors. The Company irrevocably waives, relinquishes and releases the Fund Indemnitors from any and all claims against the Fund Indemnitors for contribution, subrogation or any other recovery of any
kind in respect thereof. No advancement or payment by the Fund Indemnitors on behalf of Indemnitee with respect to any claim for which Indemnitee has sought indemnification from the Company shall affect the foregoing and the Fund Indemnitors shall
have a right of contribution or be subrogated to the extent of such advancement or payment to all of the rights of recovery of Indemnitee against the Company. The Fund Indemnitors are third party beneficiaries of the terms of this Section. 

(f)    Additional Indemnity. In addition to, and without regard to any limitations on, the indemnification
provided for in Section 3 of this Agreement, the Company shall and hereby does indemnify and hold harmless Indemnitee against all Expenses, judgments, penalties, fines and amounts paid in settlement actually incurred by
Indemnitee or on Indemnitee’s behalf if, by reason of Indemnitee’s Corporate Status, Indemnitee is, or is threatened to be made, a party to or participant in any Proceeding (including a Proceeding by or in the right of the Company),
including, without limitation, all liability arising out of the negligence or active or passive wrongdoing of Indemnitee. The only limitation that shall exist upon the Company’s obligations pursuant to this Agreement shall be that the Company
shall not be obligated to make any payment to Indemnitee that is finally determined (under the procedures, and subject to the presumptions, set forth in Sections 7 and 10 hereof) to be unlawful. 

(g)    Contribution. Whether or not the indemnification provided in this Section 3 is available, in
respect of any proceeding in which the Company is jointly liable with Indemnitee (or would be if joined in such proceeding), the Company shall pay, in the first instance, the entire amount of any judgment or settlement of such proceeding without
requiring Indemnitee to contribute to such payment and the Company hereby waives and relinquishes any right of contribution it may have against Indemnitee. The Company shall not enter into any settlement of any proceeding in which the Company is
jointly liable with Indemnitee (or would be if joined in such proceeding) unless such settlement provides for a full and final release of all 

  
 5. 













 
claims asserted against Indemnitee. Without diminishing or impairing the obligations of the Company set forth in this Section 3, if, for any reason, Indemnitee shall elect or be required to
pay all or any portion of any judgment or settlement in any threatened, pending or completed proceeding in which the Company is jointly liable with Indemnitee (or would be if joined in such proceeding), the Company shall contribute to the amount of
Expenses, judgments, fines and amounts paid in settlement incurred and paid or payable by Indemnitee in proportion to the relative benefits received by the Company and all officers, directors or employees of the Company, other than Indemnitee, who
are jointly liable with Indemnitee (or would be if joined in such proceeding), on the one hand, and Indemnitee, on the other hand, from the transaction from which such proceeding arose; provided, however, that the proportion determined
on the basis of relative benefit may, to the extent necessary to conform to law, be further adjusted by reference to the relative fault of the Company and all officers, directors or employees of the Company other than Indemnitee who are jointly
liable with Indemnitee (or would be if joined in such proceeding), on the one hand, and Indemnitee, on the other hand, in connection with the events that resulted in such Expenses, judgments, fines or settlement amounts, as well as any other
equitable considerations which the law may require to be considered. The relative fault of the Company and all officers, directors or employees of the Company, other than Indemnitee, who are jointly liable with Indemnitee (or would be if joined in
such proceeding), on the one hand, and Indemnitee, on the other hand, shall be determined by reference to, among other things, the degree to which their actions were motivated by intent to gain personal profit or advantage, the degree to which their
liability is primary or secondary and the degree to which their conduct is active or passive. 

4.    Indemnification of Expenses of Successful Party. Notwithstanding any other provision of this
Agreement, to the extent that Indemnitee has been successful on the merits or otherwise in defense of any Proceeding or in defense of any claim, issue or matter therein, including the dismissal of any action without prejudice, the Company shall
indemnify Indemnitee against all Expenses, judgments, penalties, fines and amounts paid in settlement actually incurred by or on behalf of such Indemnitee in connection with the investigation, defense or appeal of such Proceeding. If Indemnitee is
not wholly successful in such Proceeding but is successful, on the merits or otherwise, 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 incurred
by on behalf of Indemnitee 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. 
 5.    Partial
Indemnification. If Indemnitee is entitled under any provision of this Agreement to indemnification by the Company for some or a portion of any Expenses, judgments, penalties, fines and amounts paid in settlement incurred by Indemnitee in the
investigation, defense, settlement or appeal of a proceeding, but is precluded by applicable law or the specific terms of this Agreement to indemnification for the total amount thereof, the Company shall nevertheless indemnify Indemnitee for the
portion thereof to which Indemnitee is entitled. 
 6.    Advancement of Expenses. To the extent not
prohibited by law, the Company shall advance the Expenses actually incurred by Indemnitee in connection with any Proceeding, 

  
 6. 













 
and such advancement shall be made promptly following request therefor, but in any event no later than twenty (20) days after the receipt by the Company of a statement or statements
requesting such advances (which shall include invoices received by Indemnitee in connection with such 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 shall not be included with the invoice) and upon request of the Company, an undertaking to repay the advancement of expenses if and to the extent that it is ultimately determined by
a court of competent jurisdiction in a final non-appealable judgment of a court of competent jurisdiction that Indemnitee is not entitled to be indemnified by the Company. Advances shall be unsecured, interest
free and without regard to Indemnitee’s ability to repay the Expenses advanced by the Company. Advances shall include any and all Expenses actually incurred by Indemnitee pursuing an action to enforce Indemnitee’s right to indemnification
under this Agreement, or otherwise and this right of advancement, including Expenses incurred preparing and forwarding statements to the Company to support the advances claimed. Indemnitee acknowledges that the execution and delivery of this
Agreement shall constitute an undertaking providing that Indemnitee shall, to the fullest extent required by law, repay the advance if and to the extent that it is ultimately determined by a court of competent jurisdiction in a final non-appealable judgment of a court of competent jurisdiction that Indemnitee is not entitled to be indemnified by the Company. The right to advances under this Section shall continue until final disposition of any
proceeding, including any appeal therein. This Section 6 shall not apply to any claim made by Indemnitee for which indemnity is excluded pursuant to Section 10(b). The Company shall not seek from a court, or agree to, a “bar
order” which would have the effect of prohibiting or limiting the Indemnitee’s rights to receive advancement of expenses under this Agreement. 

7.    Notice and Other Indemnification Procedures. 

(a)    Notification of Proceeding. Indemnitee will notify the Company in writing promptly upon being served
with or receiving notice of any summons, citation, subpoena, complaint, indictment, information or other document relating to any proceeding or matter which may be subject to indemnification or advancement of expenses covered hereunder. The failure
of Indemnitee to so notify the Company shall not relieve the Company of any obligation which it may have to Indemnitee under this Agreement or otherwise and any delay in so notifying the Company shall not constitute a waiver by Indemnitee of any
rights under this Agreement, in each case except and solely to the extent such failure actually and materially prejudices the interests of the Company. 

(b)    Request for Indemnification and Indemnification Payments. To obtain indemnification under this
Agreement, Indemnitee shall submit to the Company a written request, including therein or therewith such documentation and information as is reasonably available to Indemnitee and is reasonably necessary to determine whether and to what extent
Indemnitee is entitled to indemnification. The Secretary of the Company shall, promptly upon receipt of such a request for indemnification, advise the Company’s Board of Directors (the “Board”) in writing that Indemnitee
has requested indemnification. Upon written request by Indemnitee for indemnification pursuant to the first sentence of this Section 7(b), a determination with respect to Indemnitee’s entitlement thereto shall be made in the specific case
by one of the following four methods, which shall be at the election of the Board: (1) by a majority vote of the 

  
 7. 













 
disinterested directors, even though less than a quorum, (2) by a committee of disinterested directors designated by a majority vote of the disinterested directors, even though less than a
quorum, (3) if there are no disinterested directors or if the disinterested directors so direct, by Independent Counsel selected by the Board in a written opinion to the Board, a copy of which shall be delivered to the Indemnitee, or
(4) if so directed by the Board, by the stockholders of the Company. For purposes hereof, disinterested directors are those members of the Board who are not parties to the Proceeding in respect of which indemnification is sought by Indemnitee.
Indemnitee shall cooperate with the person, persons or entity making the determination with respect to Indemnitee’s entitlement to indemnification, including providing to such person, persons or entity upon reasonable advance request any
documentation or information that is not privileged or otherwise protected from disclosure and that is reasonably available to Indemnitee and reasonably necessary to such determination. Unless the person, persons or entity empowered or selected
under this Section 7(b) to determine whether Indemnitee is entitled to indemnification shall determine that Indemnittee is not entitled to such indemnification, indemnification payments requested by Indemnitee under Section 3 hereof shall
be made by the Company no later than sixty (60) days after receipt of the written request of Indemnitee. Claims for advancement of expenses shall be made under the provisions of Section 6 herein. 

(c)    Independent Counsel. If the determination of entitlement to indemnification is to be made by
Independent Counsel pursuant to Section 7(b), the Independent Counsel shall be selected as provided in this Section 7(c). The Independent Counsel shall be selected by the Board. Indemnitee may, within 10 days after such written notice of
selection shall have been given, deliver to the Company 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 herein, 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 a written
objection is made and substantiated, the Independent Counsel selected may not serve as Independent Counsel unless and until such objection is withdrawn or a court has determined that such objection is without merit. If, within 20 days after
submission by Indemnitee of a written request for indemnification pursuant to Section 6(a) hereof, no Independent Counsel shall have been selected and not objected to, either the Company or Indemnitee may petition the Court of Chancery of the
State of Delaware or other court of competent jurisdiction for resolution of any objection which shall have been made by the Indemnitee to the Company’s 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, and the person with respect to whom all objections are so resolved or the person so appointed shall act as Independent Counsel under Section 7(b). The Company
shall pay any and all reasonable fees and expenses of Independent Counsel incurred by such Independent Counsel in connection with acting pursuant to Section 7(b), and the Company shall pay all reasonable fees and expenses incident to the
procedures of this Section 7(c), regardless of the manner in which such Independent Counsel was selected or appointed. 

(d)    Burden of Proof. In making a determination with respect to entitlement to indemnification hereunder,
the person or persons or entity making such determination shall presume that Indemnitee is entitled to indemnification under this Agreement. Anyone seeking to overcome this presumption shall have the burden of proof and the burden of persuasion by
clear 

  
 8. 













 
and convincing evidence. Neither the failure of the Company (including by its directors or 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 an actual determination by the Company (including by its directors or independent legal 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. 

(e)    Presumption of Good Faith. Indemnitee shall be deemed to have acted in good faith if
Indemnitee’s action is based on the records or books of account of the applicable Enterprise, including financial statements, or on information supplied to Indemnitee by the officers of the Enterprise in the course of their duties, or on the
advice of legal counsel for the Enterprise or on information or records given or reports made to the Enterprise by an independent certified public accountant or by an appraiser or other expert selected with reasonable care by the Enterprise. In
addition, the knowledge and/or actions, or failure to act, of any director, officer, agent or employee of the Enterprise shall not be imputed to Indemnitee for purposes of determining the right to indemnification under this Agreement. Whether or not
the foregoing provisions of this Section 7(e) are satisfied, it shall in any event be presumed that Indemnitee has at all times acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the
Company. Anyone seeking to overcome this presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence. The Company shall be precluded from asserting in any judicial proceeding commenced pursuant to this
Section 7 that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court that the Company is bound by all the provisions of this Agreement. 

(f)    Application for Enforcement. In the event the Company fails to make timely payments as set forth in
Sections 6 or 7(b) above or a determination is made pursuant to Section 7(b) of this Agreement that Indemnitee is not entitled to indemnification under this Agreement or no determination of entitlement to indemnification is made pursuant to
Section 7(b) of this Agreement within sixty (60) days after receipt by the Company of the request for indemnification, Indemnitee shall have the right to apply to any court of competent jurisdiction for the purpose of enforcing
Indemnitee’s right to indemnification or advancement of expenses pursuant to this Agreement. 

(g)    Indemnification of Certain Expenses. The Company shall indemnify Indemnitee against all Expenses,
judgments, penalties, fines and amounts paid in settlement actually incurred by or on behalf of such Indemnitee in connection with any hearing or proceeding under this Section 7 unless the Company prevails in such hearing or proceeding on the
merits in all material respects. 
 (h)    Final Disposition. Notwithstanding anything in this Agreement
to the contrary, no determination as to entitlement to indemnification shall be required to be made prior to the final disposition of the Proceeding. 

8.    Assumption of Defense. In the event the Company shall be requested by Indemnitee to pay the Expenses
of any Proceeding, the Company, if appropriate, shall be entitled 

  
 9. 













 
to assume the defense of such proceeding, or to participate to the extent permissible in such proceeding, with counsel reasonably acceptable to Indemnitee. Upon assumption of the defense by the
Company and the retention of such counsel by the Company, the Company shall not be liable to Indemnitee under this Agreement for any fees of counsel subsequently incurred by Indemnitee with respect to the same proceeding, provided that Indemnitee
shall have the right to employ separate counsel in such proceeding at Indemnitee’s sole cost and expense. Notwithstanding the foregoing, if Indemnitee’s counsel delivers a written notice to the Company stating that such counsel has
reasonably concluded that there may be a conflict of interest between the Company and Indemnitee in the conduct of any such defense or the Company shall not, in fact, have employed counsel or otherwise actively pursued the defense of such proceeding
within a reasonable time, then in any such event the fees and expenses of Indemnitee’s counsel to defend such proceeding shall be subject to the indemnification and advancement of expenses provisions of this Agreement. The Company shall not be
entitled to assume the defense of any action, suit or proceeding brought by or on behalf of the Company or as to which Indemnitee shall have initiated in accordance with Section 10(b). 

9.    Insurance. To the extent that the Company maintains an insurance policy or policies providing
liability insurance for directors, officers, employees, or agents of the Company or of any subsidiary (“D&O Insurance”), 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, officer, employee or agent 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 D&O 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. In addition, to the extent requested by Indemnitee and approved by the Board, the Company may at any
time and from time to time provide security to Indemnitee for the Company’s obligations hereunder through an irrevocable bank line of credit, funded trust or other collateral. Any such security, once provided to Indemnitee, may not be revoked
or released without the prior written consent of the Indemnitee. 
 10.    Exceptions. 

(a)    Certain Matters. Any provision herein to the contrary notwithstanding, the Company shall not be
obligated pursuant to the terms of this Agreement to indemnify Indemnitee on account of any proceeding with respect to (i) remuneration paid to Indemnitee if it is determined by final non-appealable
judgment of a court of competent jurisdiction that such remuneration was in violation of law; or (ii) a final non-appealable judgment of a court of competent jurisdiction rendered against Indemnitee for
disgorgement or repayment of profits made from the purchase or sale by Indemnitee of securities of the Company against Indemnitee or in connection with a settlement by or on behalf of Indemnitee to the extent it is acknowledged by Indemnitee and the
Company that such amount paid in settlement resulted from Indemnitee’s conduct from which Indemnitee received monetary personal profit, pursuant to the provisions of Section 16(b) of the Securities Exchange Act of 1934, as amended, or
other provisions of any federal, state or local statute or rules and regulations thereunder. For purposes of the foregoing sentence, a final non-appealable judgment of a court of competent jurisdiction may be
reached in 

  
 10. 













 
either the underlying proceeding or action in connection with which indemnification is sought or a separate proceeding or action to establish rights and liabilities under this Agreement. The
termination of any proceeding or of any claim, issue or matter therein, by judgment, order, settlement or conviction, or upon a plea of 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 such Indemnitee’s conduct was unlawful. For purposes of any determination of good faith, Indemnitee shall be deemed to have acted in good faith to the
extent Indemnitee relied in good faith on (i) the records or books of account of the company, including financial statements, (ii) information supplied to Indemnitee by agents of the Company in the course of their duties, (iii) the
advice of legal counsel for the Company or its Board or counsel selected by any committee of the Board or (iv) information or records given or reports made to the Company by an independent certified public accountant, an appraiser, investment
banker or other expert selected with reasonable care by the Company or its Board or any committee of the Board. 

(b)    Claims Initiated by Indemnitee. Any provision herein to the contrary notwithstanding, the Company
shall not be obligated to indemnify or advance Expenses to Indemnitee with respect to proceedings or claims initiated or brought by Indemnitee against the Company or its directors, officers, employees or other agents and not by way of defense,
except (i) with respect to proceedings brought to establish or enforce a right to indemnification under this Agreement or under any other agreement, provision in the Bylaws or Certificate of Incorporation or applicable law, or
(ii) with respect to any other proceeding initiated by Indemnitee that is either approved by the Board or Indemnitee’s participation is required by applicable law. However, indemnification or advancement of expenses may be provided by the
Company in specific cases if the Board determines it to be appropriate. 
 (c)    Unauthorized
Settlements. Any provision herein to the contrary notwithstanding, the Company shall not be obligated pursuant to the terms of this Agreement to indemnify Indemnitee under this Agreement for any amounts paid in settlement of a proceeding
effected without the Company’s written consent. Neither the Company nor Indemnitee shall unreasonably withhold consent to any proposed settlement; provided, however, that the Company may in any event decline to consent to (or to otherwise admit
or agree to any liability for indemnification hereunder in respect of) any proposed settlement if the Company is also a party in such proceeding and determines in good faith that such settlement is not in the best interests of the Company and its
stockholders. 
 (d)    Securities Act Liabilities. Any provision herein to the contrary notwithstanding,
the Company shall not be obligated pursuant to the terms of this Agreement to indemnify Indemnitee or otherwise act in violation of any undertaking appearing in and required by the rules and regulations promulgated under the Securities Act of 1933,
as amended (the “Act”), or in any registration statement filed with the SEC under the Act. Indemnitee acknowledges that paragraph (h) of Item 512 of Regulation S-K currently
generally requires the Company to undertake in connection with any registration statement filed under the Act to submit the issue of the enforceability of Indemnitee’s rights under this Agreement in connection with any liability under the Act
on public policy grounds to a court of appropriate jurisdiction and to be governed by any final adjudication of such issue. Indemnitee specifically agrees that any such undertaking shall supersede the provisions of this Agreement and to be bound by
any such undertaking. 

  
 11. 













 11.    Nonexclusivity and Survival of Rights. The
provisions for indemnification and advancement of expenses set forth in this Agreement shall not be deemed exclusive of any other rights which Indemnitee may at any time be entitled under any provision of applicable law, the Certificate of
Incorporation, Bylaws or other agreements, both as to action in Indemnitee’s official capacity and Indemnitee’s action as an agent of the Company, in any court in which a proceeding is brought, and Indemnitee’s rights hereunder shall
continue after Indemnitee has ceased acting as an agent of the Company and shall inure to the benefit of the heirs, executors, administrators and assigns of Indemnitee. This Agreement shall be binding upon and inure to the benefit of and be
enforceable by the parties hereto and their respective successors (including any direct or indirect successor by purchase, merger, consolidation or otherwise to all or substantially all of the business or assets of the Company), assigns, spouses,
heirs, executors and personal and legal representatives. The Company shall require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business or assets of the Company,
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. 

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 the DGCL, whether by statute or judicial decision, permits greater
indemnification or advancement of expenses than would be afforded currently under the Certificate of Incorporation, 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, by Indemnitee shall not prevent the concurrent assertion or employment of any other right or remedy by Indemnitee. 

The Company and Indemnitee agree herein that a monetary remedy for breach of this Agreement, at some later date, may be inadequate,
impracticable and difficult of proof, and further agree that such breach may cause Indemnitee and the Company irreparable harm. Accordingly, the parties hereto agree that each of the Company and the Indemnitee may enforce this Agreement by seeking
injunctive relief and/or specific performance hereof, without any necessity of showing actual damage or irreparable harm and that by seeking injunctive relief and/or specific performance, they shall not be precluded from seeking or obtaining any
other relief to which they may be entitled. The Company and Indemnitee further agree that they shall be entitled to such specific performance and injunctive relief, including temporary restraining orders, preliminary injunctions and permanent
injunctions, without the necessity of posting bonds or other undertaking in connection therewith. The Company and Indemnitee acknowledge that in the absence of a waiver, a bond or undertaking may be required by the Delaware Court of Chancery, and
they hereby waive any such requirement of such a bond or undertaking. 

  
 12. 













 12.    Term. This Agreement shall continue until and
terminate upon the later of: (a) five (5) years after the date that Indemnitee shall have ceased to serve as a director and/or agent of the Company; or (b) one (1) year after the final termination of any proceeding, including any appeal
then pending, in respect to which Indemnitee was granted rights of indemnification or advancement of expenses hereunder. 
 No legal action
shall be brought and no cause of action shall be asserted by or in the right of the Company against an Indemnitee or an Indemnitee’s estate, spouse, heirs, executors or personal or legal representatives after the expiration of five
(5) years from the date of accrual of such cause of action, and any claim or cause of action of the Company shall be extinguished and deemed released unless asserted by the timely filing of a legal action within such five-year period; provided,
however, that if any shorter period of limitations is otherwise applicable to such cause of action, such shorter period shall govern. 

13.    Subrogation. In the event of 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, at the request and expense of the Company, shall execute all papers required and shall do everything that may be reasonably necessary to secure such rights, including the
execution of such documents necessary to enable the Company effectively to bring suit to enforce such rights. 

14.    Interpretation of Agreement. It is understood that the parties hereto intend this Agreement to be
interpreted and enforced so as to provide indemnification to Indemnitee and Appointing Stockholder to the fullest extent now or hereafter permitted by law. 

15.    Severability. If any provision 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 the Agreement (including without limitation, all portions of any paragraphs of this Agreement containing any such provision
held to be invalid, illegal or unenforceable, that are not themselves invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby; and (b) to the fullest extent possible, the provisions of this Agreement (including,
without limitation, all portions of any paragraph of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that are not themselves invalid, illegal or unenforceable) shall be construed so as to give effect to the
intent manifested by the provision held invalid, illegal or unenforceable and to give effect to Section 14 hereof. Further, the invalidity or unenforceability of any provision hereof as to either Indemnitee or Appointing Stockholder shall in no
way affect the validity or enforceability of any provision hereof as to the other. 
 16.    Amendment and
Waiver. No supplement, modification, amendment, or cancellation of this Agreement shall be binding unless executed in writing by the parties hereto. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a
waiver of any other provision hereof (whether or not similar) nor shall such waiver constitute a continuing waiver. 

17.    Notice. Except as otherwise provided herein, any notice or demand which, by the provisions hereof, is
required or which may be given to or served upon the parties hereto shall be in writing and, if by telegram, telecopy or telex, shall be deemed to have been validly served, 

  
 13. 













 
given or delivered when sent, if by overnight delivery, courier or personal delivery, shall be deemed to have been validly served, given or delivered upon actual delivery and, if mailed, shall be
deemed to have been validly served, given or delivered three (3) business days after deposit in the United States mail, as registered or certified mail, with proper postage prepaid and addressed to the party or parties to be notified at the
addresses set forth on the signature page of this Agreement (or such other address(es) as a party may designate for itself by like notice). If to the Company, notices and demands shall be delivered to the attention of the Secretary of the Company.

 18.    Governing Law. This Agreement shall be governed exclusively by and construed according to the
laws of the State of Delaware, as applied to contracts between Delaware residents entered into and to be performed entirely within Delaware. 

19.    Counterparts. This Agreement may be executed in one or more counterparts, each of which shall for all
purposes be deemed to be an original but all of which together shall constitute but one and the same Agreement. Only one such counterpart need be produced to evidence the existence of this Agreement. 

20.    Headings. The headings of the sections of this Agreement are inserted for convenience only and shall
not be deemed to constitute part of this Agreement or to affect the construction hereof. 
 21.    No
Duplication of Payments. Except as otherwise set forth in Section 3(e) above, the Company shall not be liable under this Agreement to make any payment in connection with any claim made against Indemnitee to the extent the Indemnitee has
otherwise actually received payment (under any insurance policy, Bylaw, vote, agreement or otherwise) of the amounts otherwise indemnifiable hereunder. 

22.    Entire Agreement. This Agreement constitutes the entire agreement between the parties with respect to
the subject matter hereof and supersedes all prior agreements, understandings and negotiations, written and oral, between the parties with respect to the subject matter of this Agreement, including but not limited to any Indemnity Agreement
previously entered into between the Company and the Indemnitee; provided, however, that this Agreement is a supplement to and in furtherance of the Certificate of Incorporation, Bylaws, the DGCL and any other applicable law, and shall not be deemed
a substitute therefor, and does not diminish or abrogate any rights of Indemnitee thereunder.
