INDEMNIFICATION AGREEMENT 

This Indemnification Agreement (this “Agreement”), effective as of July 19, 2017, by and between Calyxt, Inc., a
Delaware corporation (the “Company”) and [            ] (“Indemnitee”). 

W I T N E S S E T H: 

WHEREAS, the Board of Directors of the Company (the “Board”) has determined that it is reasonable, prudent and
necessary for the Company contractually to obligate itself to indemnify, and to advance expenses on behalf of, the Company’s directors on its board of directors and officers 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, this
Agreement is a supplement to and in furtherance of the Amended and Restated Certificate of Incorporation (the “Certificate of Incorporation”) and the Amended and Restated Bylaws (the “Bylaws”) of the Company and any
resolutions adopted pursuant thereto and any liability insurance procured by the Company and shall not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder.

other entity, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior to such merger or consolidation continuing to represent (either by remaining outstanding or by being
converted into voting securities of the surviving entity) more than 51% of the combined voting power of the voting securities of the surviving entity outstanding immediately after such merger or consolidation and with the power to elect at least a

corporation, any constituent corporation (including any constituent of a constituent) absorbed in a consolidation or merger which, if its separate existence had continued, would have had power and authority to indemnify its directors, officers,

corporation, partnership, joint venture, trust or other enterprise, then Indemnitee shall stand in the same position under the provisions of this Agreement with respect to the resulting or surviving corporation as Indemnitee would have with respect

Agreement.

 ARTICLE 3 

INDEMNIFICATION 

Section 3.01. General. (a) The Company hereby agrees to and shall indemnify Indemnitee and hold Indemnitee harmless
from and against any and all Expenses and Liabilities, in either case, actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf by reason of Indemnitee’s Corporate Status, to the fullest extent permitted by applicable law.
The Company’s indemnification obligations set forth in this Section 3.01 shall apply (i) in respect of Indemnitee’s past, present and future service in any Corporate Status and (ii) regardless of whether Indemnitee is
serving in any Corporate Status at the time any such Expense or Liability is incurred. 
 For purposes of this Agreement, the meaning
of the phrase “to the fullest extent permitted by applicable law” shall include, but not be limited to: 
 (i) to
the fullest extent permitted by any provision of the General Corporation Law of the State of Delaware (“DGCL”), or the corresponding provision of any successor statute, 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 officers and directors. 
 (b) Witness
Expenses. Notwithstanding any other provision of this Agreement, to the extent that Indemnitee is, by reason of his or her Corporate Status, a witness in any Proceeding to which Indemnitee is not a party, he shall be indemnified against all
Expenses actually and reasonably incurred by Indemnitee or on his or her behalf in connection therewith. 
 (c) Expenses as
a Party Where Wholly or Partly Successful. Notwithstanding any other provisions of this Agreement, to the fullest extent permitted by applicable law, to the extent that Indemnitee is a party to (or a participant in) and is successful, on the
merits or otherwise, in any Proceeding or in defense of any claim, issue or matter therein, in whole or in part, 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, on the merits or otherwise, as to one or more but less than all claims, issues or matters in such Proceeding, the Company shall, to the fullest extent permitted by applicable
law, 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. 

  
 5 








 Section 3.02. Exclusions. Notwithstanding any provision of this Agreement and
unless Indemnitee ultimately is successful on the merits with respect to any such claim, the Company shall not be obligated under this Agreement to make any indemnity in connection with any claim made against Indemnitee: 

(a) for (i) 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 Exchange Act or similar provisions of state statutory law or common law or (ii) any reimbursement of 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, as required in each case under the Exchange Act (including any such reimbursements that arise from an accounting restatement of the Company pursuant to
Section 304 of the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”), or the payment to the Company of profits arising from the purchase and sale by Indemnitee of securities in violation of Section 306 of the
Sarbanes-Oxley Act); or 
 (b) except as otherwise provided in Sections 6.01(e), prior to a Change of Control, in connection with any
Proceeding (or any part of any Proceeding) initiated by Indemnitee (other than any cross claim or counterclaim asserted by the Indemnitee), including any Proceeding (or any part of any Proceeding) initiated by Indemnitee against the Company, Parent
or their respective directors, officers, employees or other indemnitees. 
 ARTICLE 4 

ADVANCEMENT OF EXPENSES; DEFENSE OF CLAIMS 

Section 4.01. Advances. Notwithstanding any provision of this Agreement to the contrary, the Company shall advance any
Expenses actually and reasonably incurred by Indemnitee in connection with any Proceeding within 60 days after the receipt by the Company of each statement requesting such advance 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 ability to repay such amounts and without regard to Indemnitee’s ultimate entitlement to indemnification under the other
provisions of this Agreement. Advances shall include any and all reasonable Expenses incurred pursuing an action to enforce this right of advancement, including Expenses incurred preparing and forwarding statements to the Company to support the
advances claimed.  
 Section 4.02. Repayment of Advances or Other Expenses. Indemnitee agrees that Indemnitee
shall reimburse the Company for all Expenses advanced by the Company pursuant to Section 4.01, in the event and only to the extent that  

  
 6 








 
it shall be determined by final judgment or other final adjudication under the provisions of any applicable law (as to which all rights of appeal therefrom have been exhausted or lapsed) that
Indemnitee is not entitled to be indemnified by the Company for such Expenses. 
 Section 4.03. Defense of Claims. The
Company shall be entitled to assume the defense of any Proceeding with counsel consented to by Indemnitee (such consent not to be unreasonably withheld) upon the delivery by the Company to Indemnitee of written notice of the Company’s election
to do so. After delivery of such notice, consent to 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 counsel subsequently
incurred by Indemnitee with respect to such Proceeding; provided that (i) Indemnitee shall have the right to employ separate counsel in respect of any Proceeding at Indemnitee’s expense and (ii) if (A) the employment of
counsel by Indemnitee has been previously authorized in writing by the Company or (B) Indemnitee shall have reasonably concluded upon the advice of counsel that there is a conflict of interest between the Company and Indemnitee in the conduct
of the defense of such Proceeding, then in each such case the fees and expenses of Indemnitee’s counsel shall be at the Company’s expense. 

ARTICLE 5 

PROCEDURES FOR NOTIFICATION OF AND DETERMINATION
OF ENTITLEMENT TO INDEMNIFICATION 
 Section 5.01. Notification;
Request For Indemnification. (a) As soon as reasonably practicable after receipt by Indemnitee of written notice that he or she is a party to or a participant (as a witness or otherwise) in any Proceeding or of any other matter in respect
of which Indemnitee intends to seek indemnification or advancement of Expenses hereunder, Indemnitee shall provide to the Company written notice thereof, including the nature of and the facts underlying the Proceeding. The omission by Indemnitee to
so notify the Company will not relieve the Company from any liability which it may have to Indemnitee hereunder or otherwise, except to the extent of any material and actual prejudice to the Company caused by such omission. 

(b) To obtain indemnification under this Agreement, Indemnitee shall deliver to the Company a written request for indemnification, including
therewith such information as is reasonably available to Indemnitee and reasonably necessary to determine Indemnitee’s entitlement to indemnification hereunder. Such request(s) may be delivered from time to time and at such time(s) as
Indemnitee deems appropriate in his or her sole discretion. Indemnitee’s entitlement to indemnification shall be determined according to Section 5.02 of this Agreement and applicable law. 

  
 7 








 Section 5.02. Determination of Entitlement. (a) Where there has been a written
request by Indemnitee for indemnification pursuant to Section 5.01(b), then as soon as is reasonably practicable (but in any event not later than 60 days) after final disposition of the relevant Proceeding, a determination, if required by applicable
law, with respect to Indemnitee’s entitlement thereto shall be made in the specific case: (i) if a Change of Control shall not have occurred, (A) by a majority vote of the Disinterested Directors, even though less than a quorum of the
Board, (B) by a committee of Disinterested Directors designated by a majority vote of the Disinterested Directors, even though less than a quorum of the Board, (C) if there are no such Disinterested Directors or, if such Disinterested
Directors so direct, by Independent Counsel in a written opinion to the Board, a copy of which shall be delivered to Indemnitee; or (ii) if a Change of Control shall have occurred, by Independent Counsel in a written opinion to the Board, a
copy of which shall be delivered to Indemnitee. If it is so determined that Indemnitee is entitled to indemnification, payment to Indemnitee shall be made within ten (10) days after such determination. Indemnitee shall reasonably cooperate with
the person, persons or entity making such 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 which is
not privileged or otherwise protected from disclosure and which is reasonably available to Indemnitee and reasonably necessary to such determination. Any costs or expenses (including attorneys’ fees and disbursements) actually and reasonably
incurred by Indemnitee in so cooperating with the person, persons or entity making such determination shall be borne by the Company (irrespective of the determination as to Indemnitee’s entitlement to indemnification). 

(b) If entitlement to indemnification is to be determined by Independent Counsel pursuant to Section 5.02(a)(ii), such Independent
Counsel shall be selected by Indemnitee, and Indemnitee shall give written notice to the Company advising it of the identity of the Independent Counsel so selected. If entitlement to indemnification is to be determined by Independent Counsel
pursuant to Section 5.02(a)(i)(C) (or if Indemnitee requests that such selection be made by the Board), such Independent Counsel shall be selected by the Company in which case the Company shall give written notice to Indemnitee advising him or her
of the identity of the Independent Counsel so selected. In either event, Indemnitee or the Company, as the case may be, may, within 10 days after such written notice of selection shall have been received, deliver to the Company or to 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 1 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 a court of competent jurisdiction has determined that such objection is without merit.
If,  

  
 8 








 
within 20 days after the later of submission by Indemnitee of a written request for indemnification pursuant to Section 5.01(b) hereof and the final disposition of the Proceeding, no Independent
Counsel shall have been selected and not objected to, either the Company or Indemnitee may petition a court of competent jurisdiction for resolution of any objection which shall have been made by the Company or Indemnitee to the other’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 5.02(a) hereof. Upon the due commencement of any judicial proceeding or arbitration pursuant to Section 6.01(a) of this Agreement, the Independent Counsel shall be discharged and
relieved of any further responsibility in such capacity (subject to the applicable standards of professional conduct then prevailing). 

(c) The Company agrees to pay the reasonable fees and expenses of any Independent Counsel serving under this Agreement. 

Section 5.03. Presumptions and Burdens of Proof; Effect of Certain Proceedings. (a) In making any determination with
respect to entitlement to indemnification hereunder, the person or persons or entity making such determination shall, to the fullest extent not prohibited by law, presume that Indemnitee is entitled to indemnification under this Agreement if
Indemnitee has submitted a request for indemnification in accordance with Section 5.01(b) of this Agreement, and the Company shall, to the fullest extent not prohibited by law, have the burden of proof to overcome that presumption in connection with
the making by any person, persons or entity of any determination contrary to that presumption. Neither the failure of any person, persons or entity 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 any person, persons or entity 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) If the
person, persons or entity empowered or selected under Section 5.02 of this Agreement to determine whether Indemnitee is entitled to indemnification shall not have made a determination within the 60-day period referred to in Section 5.02(a), the
requisite determination of entitlement to indemnification shall, to the fullest extent not prohibited by law, be deemed to have been made and Indemnitee shall be entitled to such indemnification, 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;
provided, however, that such 60-day period may be extended for a reasonable time, not to exceed an additional 30 days, if the  

  
 9 








 
person, persons or entity making the determination with respect to entitlement to indemnification in good faith requires such additional time for the obtaining or evaluating of documentation
and/or information relating thereto. 
 (c) 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 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. 
 (d) For purposes of any determination of good faith, Indemnitee shall be deemed to have acted in good faith if
Indemnitee’s action is in good faith reliance on the records or books of account of any Enterprise, including financial statements, or on information supplied to Indemnitee by the officers of such Enterprise in the course of their duties, or on
the advice of legal counsel for such Enterprise or on information or records given or reports made to such Enterprise by an independent certified public accountant or by an appraiser or other expert selected by such Enterprise. The provisions of
this Section 5.03(d) shall not be deemed to be exclusive or to limit in any way the other circumstances in which Indemnitee may be deemed or found to have met the applicable standard of conduct set forth in this Agreement. 

(e) The knowledge and/or actions, or failure to act, of any other director, trustee, partner, managing member, fiduciary, officer, agent or
employee of any Enterprise shall not be imputed to Indemnitee for purposes of determining any right to indemnification under this Agreement. 

ARTICLE 6 
 REMEDIES
OF INDEMNITEE 
 Section 6.01. Adjudication or Arbitration. (a) In the event of any
dispute between Indemnitee and the Company hereunder as to entitlement to indemnification or advancement of Expenses (including where (i) a determination is made pursuant to Section 5.02 of this Agreement that Indemnitee is not entitled to
indemnification under this Agreement, (ii) advancement of Expenses is not timely made pursuant to Section 4.01 of this Agreement, (iii) payment of indemnification pursuant to Section 3.01 of this Agreement is not made within 20 days after
a determination has been made that Indemnitee is entitled to indemnification, (iv) no determination as to entitlement to indemnification is timely made pursuant to Section 5.02 of this Agreement and no payment of indemnification is made
within 20 days after entitlement is deemed to have been determined pursuant to Section 5.03(b) or (v) a contribution payment is not made  

  
 10 








 
in a timely manner pursuant to Section 8.04 of this Agreement), then Indemnitee shall be entitled to an adjudication by a court of his or her entitlement to such indemnification,
contribution or advancement. 
 (b) In the event that a determination shall have been made pursuant to Section 5.02(a) of this
Agreement that Indemnitee is not entitled to indemnification, any judicial proceeding or arbitration commenced pursuant to this Section 6.01 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 6.01 the Company shall have the burden of proving Indemnitee is not entitled to indemnification or
advancement of Expenses, as the case may be, and the Company may not refer to or introduce into evidence any determination pursuant to Section 5.02(a) of this Agreement adverse to Indemnitee for any purpose. If Indemnitee commences a judicial
proceeding or arbitration pursuant to this Section 6.01, Indemnitee shall not be required to reimburse the Company for any advances pursuant to Section 4.02 until a final determination is made with respect to Indemnitee’s entitlement to
indemnification (as to which all rights of appeal have been exhausted or lapsed). 
 (c) If a determination shall have been made
pursuant to Section 5.02(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 6.01, 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 6.01 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 all Expenses and, if
requested by Indemnitee, shall (within 10 days after the Company’s receipt of such written request) advance such Expenses to Indemnitee, which are reasonably incurred by Indemnitee in connection with any judicial proceeding or arbitration
brought by Indemnitee for (i) indemnification or advances of Expenses by the Company (or otherwise for the enforcement, interpretation or defense of his or her rights) under this Agreement or any other agreement, including any other
indemnification, contribution or advancement agreement, or any provision of the Company’s Certificate of Incorporation or Bylaws now or hereafter in effect or (ii) recovery or advances under any directors’ and officers’ liability
insurance policy maintained by the Company, regardless of whether Indemnitee ultimately is determined to be entitled to such indemnification, contribution, advancement or insurance recovery, as the case may be.

 ARTICLE 7 

DIRECTORS’ AND OFFICERS’ LIABILITY INSURANCE 

Section 7.01. D&O Liability Insurance. The Company and/or Parent shall obtain and maintain a policy or policies of insurance
(“D&O Liability Insurance”) with reputable insurance companies providing liability insurance for directors and officers of the Company in their capacities as such (and for any capacity in which any director or officer of the
Company serves any other Enterprise at the request of the Company), in respect of acts or omissions occurring while serving in such capacity, on terms with respect to coverage and amount (including with respect to the payment of Expenses) no less
favorable than those of such policy in effect on the date hereof, except for any changes approved by the Board prior to a Change of Control; provided that such coverage and amounts are available on commercially reasonable efforts. 

Section 7.02. Evidence of Coverage. Upon request by Indemnitee, the Company shall provide copies of all policies of D&O
Liability Insurance obtained and maintained in accordance with Section 7.01 of this Agreement.  
 ARTICLE 8 

MISCELLANEOUS 

Section 8.01. Nonexclusivity of Rights. The rights of indemnification, contribution and advancement of Expenses as provided
by this Agreement shall not be deemed exclusive of any other rights to which Indemnitee may at any time be entitled to under applicable law, the Company’s Certificate of Incorporation, the Company’s Bylaws, any agreement, a vote of
stockholders or a resolution of directors, or otherwise. 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. 
 Section 8.02. Insurance and Subrogation. (a) Indemnitee shall be covered by the Company’s
D&O Liability Insurance in accordance with its or their terms to the maximum extent of the coverage available for any director or officer under such policy or policies. If, at the time the Company receives notice of a claim hereunder, the
Company has director and officer liability insurance in effect, the Company shall give prompt notice of such Proceeding to the insurers in accordance with the procedures set forth in the respective policies. The Company 


  
 12 








 
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. The failure or refusal of any such insurer to pay any such amount shall not affect or impair the obligations of the Company under this Agreement. 

(b) 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. 

(c) The Company shall not be liable under this Agreement to make any payment of amounts otherwise indemnifiable (or for which advancement is
provided) hereunder if and to the extent that Indemnitee has actually received such payment under any insurance policy or other indemnity provision. 

(d) The Company’s obligation to indemnify or advance Expenses hereunder to Indemnitee who is or was serving at the request of the Company
as a director, officer, trustee, partner, managing member, fiduciary, board of directors’ committee member, employee or agent of any other Enterprise shall be reduced by any amount Indemnitee has actually received as indemnification or
advancement of Expenses from such Enterprise. 
 Section 8.03. Contribution. To the fullest extent permissible under
applicable law, if the indemnification provided for in this Agreement is unavailable to Indemnitee for any reason whatsoever, the Company, in lieu of indemnifying Indemnitee, shall contribute to the amount incurred by Indemnitee, whether for
judgments, fines, penalties, excise taxes, amounts paid or to be paid in settlement and/or for Expenses, in connection with any claim relating to an indemnifiable event under this Agreement, in such proportion as is deemed fair and reasonable in
light of all of the circumstances of such Proceeding in order to reflect (i) the relative benefits received by the Company and Indemnitee as a result of the event(s) and/or transaction(s) giving rise to such Proceeding; and/or (ii) the
relative fault of the Company (and its directors, officers, employees and agents) and Indemnitee in connection with such event(s) and/or transaction(s).

expressly provided herein, no delay on the part of any party hereto in exercising any right, power or privilege hereunder shall operate as a waiver thereof, nor shall  

  
 13 








 
any waiver on the part of any party hereto of any right, power or privilege hereunder operate as a waiver of any other right, power or privilege hereunder nor shall any single or partial exercise
of any right, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, power or privilege hereunder. 

Section 8.06. Entire Agreement. This Agreement and the documents referred to herein constitute the entire agreement between
the parties hereto with respect to the matters covered hereby, and any other prior or contemporaneous oral or written understandings or agreements with respect to the matters covered hereby are superseded by this Agreement, provided that this

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 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 8.08. Notices. All notices, requests, demands and other communications under this Agreement shall be in writing

parties hereto and their respective successors, assigns, including any direct or indirect successor by purchase, merger, consolidation or otherwise to all or substantially all of the business and/or assets of the Company, spouses, heirs, and

business 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 manner and to the same extent that the Company would be required to perform if
no such succession had taken place. 
 (c) The indemnification, contribution and advancement of Expenses provided by, or granted pursuant to
this Agreement shall continue as to a person who has ceased to be a director or officer and shall inure to the benefit of the heirs, executors, administrators, legatees and assigns of such a person.

Court for purposes of any action or proceeding arising out of or in connection with this Agreement, (iii) waive any objection to the laying of venue of any such action or proceeding in the Delaware Court, and (iv) waive, and agree not to
plead or to make, any claim that any such action or proceeding brought in the Delaware Court has been brought in an improper or inconvenient forum.
