CODIAK BIOSCIENCES, INC. 

[FORM OF] OFFICER INDEMNIFICATION AGREEMENT 

This Indemnification Agreement (“Agreement”) is made as of
[                    ] by and between Codiak BioSciences, Inc., a Delaware corporation (the “Company”), and [Officer]
(“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 	 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. 

Section 2. Definitions. 

As used in this Agreement: 
 (a)
“Change in Control” shall mean (i) the sale of all or substantially all of the assets of the Company on a consolidated basis to an unrelated person or entity, (ii) a merger, reorganization or consolidation pursuant to which the
holders of the Company’s outstanding voting power and outstanding stock immediately prior to such transaction do not own a majority of the outstanding voting power and outstanding stock or other equity interests of the resulting or successor
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
request of the Company.

transcript costs, fees of experts, travel expenses, duplicating costs, printing and binding costs, telephone charges, postage, delivery service fees, and all other
out-of-pocket disbursements or expenses of the types customarily incurred in connection with an action to enforce indemnification or advancement rights, or an appeal
from such action. Expenses, however, shall not include fees, salaries, wages or benefits owed to Indemnitee. 
 (d)

 (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, as amended (“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 

  
 10 

 
commenced by Indemnitee pursuant to Section 12 of this Agreement relating thereto. This 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.

Company in writing upon being served with any summons, citation, subpoena, complaint, indictment, information or other document relating to any Proceeding or matter which may be subject to indemnification, reimbursement or advancement as provided

with respect to a bona fide claim against Indemnitee or the Company do not provide for a deferral of compensation, subject to Section 409A of the Code, where such claim is based on actions or failures to act by Indemnitee in his or her capacity
as a service provider of the Company. The parties intend that this Agreement be interpreted and construed with such intent.

 Exhibit 10.1 

INDEMNITY AGREEMENT 
 THIS
INDEMNITY AGREEMENT (“Agreement”), effective as of [*], is made by and between Chaparral Energy, Inc., a Delaware corporation with executive offices located at 701 Cedar Lake Blvd., Oklahoma City, Oklahoma 73114 (the “Company”),
and [*] of the Company, residing at [*] (the “Indemnitee”). 
 The Company and Indemnitee recognize the prevalent risk of
corporate shareholder litigation, in general, subjecting directors to the risk of expensive litigation. 
 The Company’s Board of
Directors has determined that, in order to attract and retain qualified individuals, the Company will attempt to maintain on an ongoing basis, at its sole expense, liability insurance to protect persons serving the Company from certain liabilities.
Although the furnishing of such insurance has been a customary and widespread practice among United States-based corporations and other business enterprises, the Company believes that, given current market conditions and trends, such insurance may
be available to it in the future only at higher premiums and with more exclusions. At the same time, directors, officers, and other persons in service to corporations or business enterprises are being increasingly subjected to expensive and
time-consuming litigation relating to, among other things, matters that traditionally would have been brought only against the Company or business enterprise itself. The Amended and Restated Bylaws of Chaparral Energy, Inc. (“Bylaws”) and
the Third Amended and Restated Certificate of Incorporation if Chaparral Energy, Inc. (“Certificate of Incorporation”) requires indemnification of the directors of the Company. 

Indemnitee may also be entitled to indemnification pursuant to the Delaware General Corporation Law (“DGCL”).
Section 145 of the DGCL, empowers the Company to indemnify by agreement its officers, directors, employees and agents, and persons who serve, at the request of the Company, as directors, officers, employees or agents of other corporations or
enterprises, and expressly provides that the indemnification provided by Section 145 is 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; 
 Given the uncertainties relating to such insurance and to indemnification have increased the
difficulty of attracting and retaining such persons, 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. 

This Agreement is a supplement to and in furtherance of the Bylaws and Certificate of Incorporation and any resolutions adopted pursuant
thereto, and shall not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder. 
 Indemnitee does
not regard the protection available under the Bylaws and Certificate of Incorporation and insurance as adequate in the present circumstances, and may not be willing to serve as an officer or director without adequate protection, and the Company
desires Indemnitee to serve in such capacity. Indemnitee is willing to serve, continue to serve and to take on additional service for or on behalf of the Company on the condition that he or she is so indemnified. 

NOW, THEREFORE, in consideration of Indemnitee’s agreement to serve as a director from and after the date hereof, the parties agree as
follows: 
 1. Definitions. 

(a) Agent. For the purposes of this Agreement, “Agent” of the Company means any person who (i) is or was a director,
officer, employee, agent or other fiduciary of the Company or a Subsidiary of the Company (as defined herein); (ii) is or was serving at the request of, for the convenience of or to represent the interest of the Company or a Subsidiary of the
Company as a director, officer, employee, agent or other fiduciary of a foreign or domestic corporation, partnership, joint venture, trust or other enterprise; (iii)was a director, officer, employee, agent or other fiduciary of a foreign or domestic
corporation which was a predecessor corporation of the Company or a Subsidiary of the Company, or (iv) was a director, officer, employee, agent or other fiduciary of another enterprise at the request of, for the convenience of or to represent
the interests of such predecessor corporation. 

  
 1 

 (b) Expenses. For purposes of this Agreement, the term “Expenses” shall be
broadly construed and shall include, without limitation, all direct and indirect costs of any type or nature whatsoever (including, without limitation, all attorneys’ fees, retainers, court costs, transcript costs, fees of experts, witness
fees, travel expenses, printing and binding costs, telephone charges, postage, delivery service fees and all other disbursements or expenses of the types customarily incurred in connection with prosecuting, defending, preparing to prosecute or
defend, investigating, participating, or being or preparing to be a witness in a Proceeding, or responding to, or objecting to, a request to provide discovery in any Proceeding and related disbursements, and other out-of-pocket costs actually and reasonably incurred by the Indemnitee in connection with either the investigation, defense or appeal of a Proceeding or establishing or enforcing a right to indemnification
under this Agreement, the DGCL or otherwise). The term “Expenses” shall also include reasonable compensation for time spent by Indemnitee for which he or she is not compensated by the Company or any Subsidiary of the Company or third party
(i) 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 of the Company; and (ii) if the rate of compensation and estimated time involved are
approved by the directors of the Company who are not parties to any action with respect to which expenses are incurred, for Indemnitee while an Agent of, employed by, or providing services for compensation to, the Company or any Subsidiary of the
Company. 
 (c) Liabilities. For purposes of this Agreement, the term “Liabilities” shall be broadly construed
and shall include, without limitation, judgments, damages, deficiencies, liabilities, losses, penalties, excise taxes, fines, assessments and amounts paid in settlement, including any interest and any federal, state, local or foreign taxes imposed
as a result of the actual or deemed receipt of any payment under this Agreement. 
 (d) Proceeding. For the purposes of this
Agreement, the term “Proceeding” shall be broadly construed and shall include, without limitation, any threatened, pending, or completed action, suit, claim, counterclaim, cross claim, arbitration, mediation, alternative dispute resolution
mechanism, claim, investigation, inquiry, administrative hearing, or any other actual, threatened, completed or other proceeding, whether brought by or in the right of the Company or any Subsidiary of the Company or otherwise and whether civil,
criminal, administrative, investigative or any other type whatsoever and whether formal or informal. If the Indemnitee believes in good faith that a given situation may lead to or culminate in the institution of a proceeding, this shall be
considered a proceeding under this paragraph. 
 (e) Subsidiary. For purposes of this Agreement, “Subsidiary” means any
corporation, limited liability company or other entity of which more than 50% of the outstanding voting securities or equity interests are owned directly or indirectly by the Company, by the Company and one or more other subsidiaries, or by one or
more other subsidiaries, and any other corporation, limited liability company, partnership, joint venture, trust, employee benefit plan, or other enterprise of which Indemnitee is or was serving at the request of the Company as an Agent. 

2. Agreement to Serve. The Indemnitee agrees to serve and/or continue to serve as an Agent of the Company, in the capacity the
Indemnitee currently serves, so long as he or she is duly appointed or elected and qualified in accordance with the applicable provisions of the Bylaws of the Company or any Subsidiary of the Company or until such time as he or she tenders his
resignation in writing or he or she is removed from such position, provided, however, that nothing contained in this Agreement is intended to create any right to continued employment by the Indemnitee. 

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, or continue to serve, as an Agent, and the Company acknowledges that Indemnitee is relying upon this Agreement in serving as an Agent. 

  
 2 

 3. Maintenance of Liability Insurance. 

The Company hereby covenants and agrees that, so long as the Indemnitee shall continue to serve as an Agent of the Company and thereafter so
long as the Indemnitee shall be subject to any possible Proceeding by reason of the fact that the Indemnitee was an Agent of the Company, the Company shall use reasonable efforts to obtain and maintain in full force and effect directors’ and
officers’ liability insurance (“D&O Insurance”) in reasonable amounts from established and reputable insurers. 
 4.
Mandatory Indemnification. Subject to Section 10 below, the Company shall indemnify the Indemnitee to the fullest extent permitted by the DGCL, as the same may be amended from time to time (but, to the fullest extent of the law, only to
the extent that such amendment permits Indemnitee to broader indemnification rights than the DGCL permitted prior to adoption of such amendment) from: 

(a) Third Party Actions. If the Indemnitee was or is a party or is threatened to be made a party to or otherwise involved in any
Proceeding, other than a Proceeding by or in right of the Company to procure a judgment in its favor, by reason of the fact that he or she is or was an Agent of the Company, or by reason of anything done or not done by him or her in any such
capacity, against any and all Expenses and Liabilities (including all interest, assessments and other charges paid or payable in connection with or in respect of such Expenses and Liabilities) incurred by him or her in connection with the
investigation, defense, settlement or appeal of such Proceeding if he or she 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, with respect to any criminal action or
Proceeding, had no reasonable cause to believe his or her conduct was unlawful; and 
 (b) Derivative Actions. If the Indemnitee was
or is a party or is threatened to be made a party to or otherwise involved in any Proceeding by or in the right of the Company to procure a judgment in its favor by reason of the fact that he or she is or was an Agent of the Company, or by reason of
anything done or not done by him or her in any such capacity, against any amounts paid in settlement of any such Proceeding and all Expenses actually and reasonably incurred by him or her in connection with the investigation, defense, settlement, or
appeal of such Proceeding if he or she 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; except that no indemnification under this subsection shall be made in respect of
any claim, issue or matter as to which such person shall have been finally adjudged to be liable to the Company after the time for an appeal has expired by a court of competent jurisdiction due to willful misconduct of a culpable nature in the
performance of his or her duty to the Company unless and only to the extent that the Court of Chancery or the court in which such Proceeding was brought shall determine upon application that, despite the adjudication of liability but in view of all
the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such amounts which the Court of Chancery or such other court shall deem proper; and 

(c) Exception for Amounts Covered by Insurance. Notwithstanding the foregoing, the Company shall not be obligated to indemnify the
Indemnitee for Expenses or Liabilities which have been paid directly to Indemnitee under D&O Insurance. 
 5. Partial
Indemnification. If the Indemnitee is entitled under any provision of this Agreement to indemnification by the Company for some or a portion of any Expenses or liabilities of any type whatsoever (including, but not limited to, judgments, fines,
ERISA excise taxes or penalties, and amounts paid in settlement) incurred by him or her in the investigation, defense, settlement or appeal of a Proceeding but not entitled, however, to indemnification for all of the total amount thereof, the
Company shall nevertheless indemnify the Indemnitee for such total amount except as to the portion thereof to which the Indemnitee is not entitled. 

6. Advancement of Expenses. Subject to Section 10 below, to the fullest extent to which it is permitted to do so by the DGCL or
other applicable law, the Company shall, in advance of the final disposition of the matter, pay the Expenses and costs (including attorneys’ fees) actually and reasonably incurred by any Indemnitee in defending or otherwise participating in
connection with the investigation, defense, settlement or appeal of any Proceeding to which the Indemnitee is a party or is threatened to be made a party by reason of the fact that the Indemnitee is or was an Agent of the Company or by reason of
anything done or not done by him or her in any such capacity, and any appeal therefrom for which such Indemnitee may be entitled to such indemnification 

  
 3 

 
under this Agreement; provided, however, if required by the DGCL, such payment of Expenses and costs in advance of the final disposition of the Proceeding shall be made only upon
receipt by the Company of an undertaking by or on behalf of such Indemnitee to repay all amounts advanced if it should be ultimately determined by final judicial decision from which there is no further right to appeal that such Indemnitee is not
entitled to be indemnified for such Expenses. Advances shall be unsecured, interest free and without regard to Indemnitee’s ability to repay the Expenses. Advances shall include any and all Expenses 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 hereby
undertakes to repay such amounts advanced only if, and to the extent that, it shall ultimately be determined by a court of competent jurisdiction in a final judgment, not subject to appeal, that the Indemnitee is not entitled to be indemnified by
the Company. The advances to be made hereunder shall be paid by the Company to the Indemnitee within twenty (20) days following delivery of a written request therefor by the Indemnitee to the Company. 

7. Notice and Other Indemnification Procedures. 

(a) Promptly after receipt by the Indemnitee of notice of the commencement of or the threat of commencement of any Proceeding, the Indemnitee
shall, if the Indemnitee believes that indemnification with respect thereto may be sought from the Company under this Agreement, notify the Company of the commencement or threat of commencement thereof. 

(b) If, at the time of the receipt of a notice of the commencement of a Proceeding pursuant to Section 7(a) 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 the Indemnitee, all amounts payable as a result of such Proceeding in accordance with the terms of such policies. 

(c) Any indemnification or advancement of Expenses under this Agreement shall be made promptly, and in any event within thirty (30) days,
upon the written request of the Indemnitee. If a determination by the Company that the Indemnitee is entitled to indemnification is required, and the Company fails to respond within sixty (60) days to a written request for indemnity, the
Company shall be deemed to have approved the request. If the Company denies a written request for indemnification or advancement of expenses, in whole or in part, or if tender of such request is not made within thirty (30) days (or twenty
(20) days in the case of a claim for advancement of expenses), the right to indemnification or advancement of expenses as granted by this Agreement shall be enforceable by the Indemnitee in any court of competent jurisdiction. Such
Indemnitee’s Expenses incurred in connection with successfully establishing the right to indemnification, in whole or in part, in any such action or in a suit brought by the Company to recover an advancement of expenses pursuant to the terms of
an undertaking, shall also be indemnified by the Company. It shall be a defense to any such action (other than an action brought to enforce a claim for expenses incurred in defending any proceeding in advance of its final disposition where the
required undertaking, if any, has been tendered to the Company) that the Indemnitee has not met the standards of conduct which make it permissible under the DGCL for the Company to indemnify the Indemnitee for the amount claimed, but the burden of
such defense shall be on the Company. 
 (d) In any suit brought by the Indemnitee to enforce a right to indemnification or to an advancement
of expenses hereunder, or brought by the Company to recover an advancement of expenses pursuant to the terms of an undertaking, the burden of proving that the Indemnitee is not entitled to be indemnified, or to such advancement of expenses, under
this Agreement or otherwise, shall be on the Company. 
 (e) In the event the Company shall be obligated to advance the Expenses for
any Proceeding against the Indemnitee, the Company, if appropriate, shall be entitled to assume the defense of such Proceeding, with counsel approved by the Indemnitee, upon the delivery to the Indemnitee of written notice of its election so to do.
After delivery of such notice, approval of such counsel by the Indemnitee and the retention of such counsel by the Company, the Company will not be liable to the Indemnitee under this Agreement for any fees of counsel subsequently incurred by the
Indemnitee with respect to the same Proceeding, provided that (i) the Indemnitee shall have the right to employ his or her counsel in any such Proceeding at the Indemnitee’s 

  
 4 

 
expense; and (ii) if (A) the employment of counsel by the Indemnitee has been previously authorized by the Company, (B) the Indemnitee shall have reasonably concluded that there
may be a conflict of interest between the Company and the Indemnitee in the conduct of any such defense or (C) the Company shall not, in fact, have employed counsel to assume the defense of such Proceeding, the fees and expenses of the
Indemnitee’s counsel shall be at the expense of the Company. 
 8. Determination of Right to Indemnification. 

(a) To the extent the Indemnitee has been successful on the merits or otherwise in defense of any Proceeding referred to in Section 4(a),
4(b) or 4(c) of this Agreement or in the defense of any claim, issue or matter described therein, the Company shall indemnify the Indemnitee against Expenses actually and reasonably incurred by him or her in connection therewith. 

(b) In the event that Section 8(a) is inapplicable, the Company shall indemnify the Indemnitee unless, and only to the extent that, the
Company shall prove by clear and convincing evidence to a forum listed in Section 8(c) below that the Indemnitee has not met the applicable standard of conduct required to entitle the Indemnitee to such indemnification. 

(c) The Indemnitee shall be entitled to select the forum in which the validity of the Company’s claim under Section 8(b) hereof that
the Indemnitee is not entitled to indemnification will be heard from among the following: 
 (1) A quorum of the Board consisting of
directors who are not parties to the Proceeding for which indemnification is being sought; 
 (2) The stockholders of the Company; 

(3) Legal counsel selected by the Indemnitee and reasonably approved by the Board, which counsel shall make such determination in a written
opinion; 
 (4) A panel of three arbitrators, one of whom is selected by the Company, another of whom is selected by the Indemnitee and the
last of whom is selected by the first two arbitrators so selected. 
 (d) As soon as practicable, and in no event later than 30 days after
written notice of the Indemnitee’s choice of forum pursuant to Section 8(c) above, the Company shall, at its own expense, submit to the selected forum in such manner as the Indemnitee or the Indemnitee’s counsel may reasonably
request, its claim that the Indemnitee is not entitled to indemnification; and the Company shall act in the utmost good faith to assure the Indemnitee a complete opportunity to defend against such claim. 

(e) Notwithstanding a determination by any forum listed in Section 8(c) hereof that the Indemnitee is not entitled to indemnification with
respect to a specific Proceeding, the Indemnitee shall have the right to apply to the Court of Chancery of Delaware, the court in which that Proceeding is or was pending or any other court of competent jurisdiction, for the purpose of enforcing the
Indemnitee’s right to indemnification pursuant to the Agreement. 
 (f) The Company shall indemnify the Indemnitee against all Expenses
incurred by the Indemnitee in connection with any hearing or Proceeding under this Section 8 involving the Indemnitee and against all Expenses incurred by the Indemnitee in connection with any other Proceeding between the Company and the
Indemnitee involving the interpretation or enforcement of the rights of the Indemnitee under this Agreement unless a court of competent jurisdiction finds that each of the material claims and/or defenses of the Indemnitee in any such Proceeding was
frivolous or not made in good faith. 
 9. Limitation of Actions and Release of Claims. No Proceeding shall be brought and no cause of
action shall be asserted by or on behalf of the Company or any Subsidiary against the Indemnitee, his or her spouse, heirs, estate, executors or administrators after the expiration of one year from the act or omission of the Indemnitee upon which
such Proceeding is based; however, in a case where the Indemnitee fraudulently conceals the facts underlying such cause of action, no Proceeding shall be brought and no cause of action shall be asserted after the expiration of one year from the
earlier of (i) the date the Company or any Subsidiary of the Company 

  
 5 

 
discovers such facts, or (ii) the date the Company or any Subsidiary of the Company could have discovered such facts by the exercise of reasonable diligence. Any claim or cause of action of
the Company or any Subsidiary of the Company, including claims predicated upon the negligent act or omission of the Indemnitee, shall be extinguished and deemed released unless asserted by filing of a legal action within such period. This
Section 9 shall not apply to any cause of action which has accrued on the date hereof and of which the Indemnitee is aware on the date hereof, but as to which the Company has no actual knowledge apart from the Indemnitee’s knowledge. 

10. Exceptions. Any other provision herein to the contrary notwithstanding, the Company shall not be obligated pursuant to the terms of
this Agreement: 
 (a) Claims Initiated by Indemnitee. To indemnify or advance Expenses to the Indemnitee with respect to Proceedings
or claims initiated or brought voluntarily by the Indemnitee and not by way of defense, except with respect to Proceedings brought to establish or enforce a right to indemnification under this Agreement or any other statute or law or otherwise as
required under Section 145, but such indemnification or advancement of Expenses may be provided by the Company in specific cases if the Board of Directors finds it to be appropriate; or 

(b) Lack of Good Faith. To indemnify the Indemnitee for any Expenses incurred by the Indemnitee with respect to any Proceeding
instituted by the Indemnitee to enforce or interpret this Agreement, if a court of competent jurisdiction determines that each of the material assertions made by the Indemnitee in such Proceeding was not made in good faith or was frivolous; or 

(c) Unauthorized Settlements. To indemnify the Indemnitee under this Agreement for any amounts paid in settlement of a Proceeding unless
the Company consents to such settlement; or 
 (d) Claims by the Company for Willful Misconduct. To indemnify the Indemnitee under
this Agreement for any Expenses incurred by the Indemnitee with respect to any Proceeding or claim brought by the Company against the Indemnitee for willful misconduct, unless a court of competent jurisdiction determines that such claim was not made
in good faith or was frivolous; or 
 (e) Section 16(b). To indemnify Indemnitee for Expenses and the payment of
profits arising from the purchase and sale by Indemnitee of securities in violation of Section 16(b) of the Securities Exchange Act of 1934, as amended, or any similar successor statute; or 

(f) Willful Misconduct. To indemnify the Indemnitee on account of the Indemnitee’s conduct which is finally adjudged to have been
knowingly fraudulent or deliberately dishonest, or to constitute willful misconduct; or 
 (g) Unlawful Indemnification. To indemnify
the Indemnitee if a final decision by a court having jurisdiction in the matter shall determine that such indemnification is not lawful; or 

(h) Forfeiture of Certain Bonuses and Profits. To indemnify Indemnitee for the payment of amounts required to be reimbursed to the
Company pursuant to Section 304 of the Sarbanes-Oxley Act of 2002, as amended, or any similar successor statute. 
 11.
Nonexclusivity. The provisions for indemnification and advancement of Expenses set forth in this Agreement shall not be deemed exclusive of any other rights which the Indemnitee may have under any provision of law, the Company’s
Certificate of Incorporation or Bylaws, the vote of the Company’s stockholders or disinterested directors, other agreements, or otherwise, both as to actions in his or her official capacity and to actions in another capacity while occupying his
or her position as an Agent of the Company, and the Indemnitee’s rights hereunder shall continue after the Indemnitee has ceased acting as an Agent of the Company and shall inure to the benefit of the heirs, executors and administrators of the
Indemnitee. 
 12. Interpretation of Agreement. It is understood that the parties hereto intend this Agreement to be interpreted and
enforced so as to provide indemnification to the Indemnitee to the fullest extent now or hereafter permitted by law. 

  
 6 

 13. Severability. If any provision or provisions of this Agreement shall be held to
be invalid, illegal or unenforceable for any reason whatsoever, (i) 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 (ii) to the fullest extent possible, the provisions
of this 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 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 12 hereof. 

14. Modification and Waiver. No supplement, modification or amendment of this Agreement shall be binding unless executed in writing by
both of 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. 

15. Successors and Assigns. The terms of this Agreement shall bind, and shall inure to the benefit of, the successors, heirs, executors,
and administrators and assigns of the parties hereto. 
 16. Notice. All notices, requests, demands and other communications under
this Agreement shall be in writing and shall be deemed duly given (i) if delivered by hand and receipted for by the party addressee or (ii) if mailed by certified or registered mail with postage prepaid, on the third business day after the
mailing date. Addresses for notice to either party are as shown on the signature page of this Agreement, or as subsequently modified by written notice. 

17. 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. 
 18. 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
determined by the members of the Board of Directors of the Company who are not parties to any action with respect to which such amounts are incurred to be fair and reasonable in light of all of the circumstances of such Proceeding in order to
