Director Indemnification Agreement



 Exhibit 10.57 
 DIRECTOR INDEMNIFICATION AGREEMENT 
 This Director Indemnification
Agreement, dated as of April 15, 2008 (this “Agreement”), is made by and between Kayak Software Corporation (the “Company”) and Harry Nelis (“Indemnitee”). 

RECITALS: 

A. Section 141 of the Delaware General Corporation Law provides that the business and affairs of a corporation shall be managed by
or under the direction of its board of directors. 
 B. Indemnitee is a director of the Company and his/her willingness to serve
in such capacity is predicated, in substantial part, upon the Company’s willingness to indemnify him/her in accordance with the principles reflected herein, to the fullest extent permitted by the laws of the state of Delaware, and upon the
other undertakings set forth in this Agreement. 
 C. Therefore, in recognition of the need to provide Indemnitee with
substantial protection against personal liability, in order to procure Indemnitee’s continued service as a director of the Company and to enhance Indemnitee’s ability to serve the Company in an effective manner, and in order to provide
such protection pursuant to express contract rights (intended to be enforceable irrespective of, among other things, any amendment to the Company’s certificate of incorporation or bylaws (collectively, the “Constituent
Documents”), any change in the composition of the Company’s Board of Directors (the “Board”) or any change-in-control or business combination transaction relating to the Company), the Company wishes to
provide in this Agreement for the indemnification of and the advancement of Expenses (as defined in Section 1(e)) to Indemnitee as set forth in this Agreement and for the continued coverage of Indemnitee under the Company’s directors’
and officers’ liability insurance policies. 
 D. In light of the considerations referred to in the preceding recitals, it
is the Company’s intention and desire that the provisions of this Agreement be construed liberally, subject to their express terms, to maximize the protections to be provided to Indemnitee hereunder. 

AGREEMENT: 
 NOW, THEREFORE, the parties hereby agree as follows: 
 (i) Certain
Definitions. In addition to terms defined elsewhere herein, the following terms have the following meanings when used in this Agreement with initial capital letters: 
 (a) “Change in Control” means the occurrence after the date of this Agreement of any of the following events: 

(i) the consummation of a reorganization, merger or consolidation, or sale or other disposition of all or substantially all of the
assets of the Company or the acquisition of assets of another corporation, or other transaction (each, a “Business Combination”), unless, in each case, immediately following such Business Combination A) all or substantially
all of the beneficial owners of voting stock of the Company immediately prior to such Business Combination beneficially own, directly or indirectly, more than 60% of the combined voting power of the then outstanding shares of voting stock of the
entity resulting from such Business Combination or 
 (ii) approval by the stockholders of the Company of a complete
liquidation or dissolution of the Company. 
 (b) “Incumbent Directors” means the individuals who, as of
the date hereof, are Directors of the Company and any individual becoming a Director subsequent to the date hereof whose election, nomination for election by the Company’s stockholders, or appointment, was approved by a vote of at least
two-thirds of the then Incumbent Directors (either by a specific vote or by approval of the proxy statement of the Company in which such person is named as a nominee for director, without objection to such nomination). 

(c) “Subsidiary” means an entity in which the Company directly or indirectly beneficially owns 50% or more of the
outstanding Voting Stock. 
 (d) “Voting Stock” means securities entitled to vote generally in the
election of directors (or similar governing bodies). 







 (e) “Claim” means (i) any threatened, asserted,
pending or completed claim, demand, action, suit or proceeding, whether civil, criminal, administrative, arbitrative, investigative or other, and whether made pursuant to federal, state or other law; and (ii) any inquiry or investigation,
whether made, instituted or conducted by the Company or any other party, including without limitation any federal, state or other governmental entity, that Indemnitee determines might lead to the institution of any such claim, demand, action, suit
or proceeding. 
 (f) “Disinterested Director” means a director of the Company who is not and was not a
party to the Claim in respect of which indemnification is sought by Indemnitee. 
 (g)
“Expenses” means reasonable attorneys’ and experts’ fees and expenses and all other reasonable costs and expenses paid or payable in connection with investigating, defending, being a witness in or
participating in (including on appeal), or preparing to investigate, defend, be a witness in or participate in (including on appeal), any Claim. 
 (h) “Indemnifiable Claim” means any Claim based upon, arising out of or resulting from (i) any actual, alleged or suspected act or failure to act by Indemnitee
in his or her capacity as a director, officer, employee or agent of the Company or as a director, officer, employee, member, manager, trustee or agent of any other corporation, limited liability company, partnership, joint venture, trust or other
entity or enterprise, whether or not for profit, as to which Indemnitee is or was serving at the request of the Company as a director, officer, employee, member, manager, trustee or agent, or (ii) Indemnitee’s status as a current or former
director, officer, employee or agent of the Company or as a current or former director, officer, employee, member, manager, trustee or agent of the Company or any other entity or enterprise referred to in clause (i) of this sentence or any
actual, alleged or suspected act or failure to act by Indemnitee in connection with any obligation or restriction imposed upon Indemnitee by reason of such status. 
 (i) “Indemnifiable Losses” means any and all Losses relating to, arising out of or resulting from any Indemnifiable Claim. 

(j) “Independent Counsel” means a law firm, or a member of a law firm, that is experienced in matters of
corporation law and neither presently is, nor in the past five years has been, retained to represent: (i) the Company or Indemnitee in any matter material to either such party (other than with respect to matters concerning the Indemnitee under
this Agreement, or of other indemnitees under similar indemnification agreements), or (ii) any other party to the Indemnifiable Claim 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. 
 (k) “Losses” means any and all Expenses,
damages, losses, liabilities, judgments, fines, penalties (whether civil, criminal or other) and reasonable amounts paid in settlement, including without limitation all interest, assessments and other charges paid or payable in connection with or in
respect of any of the foregoing, excluding short-swing trading profits prohibited under Section 16(b) of the Securities Exchange Act of 1934. 
 2. Indemnification Obligation. Subject to Section 7, the Company shall indemnify, defend and hold harmless Indemnitee, to the fullest extent permitted by the laws of the State of Delaware in
effect on the date hereof or as such laws may from time to time hereafter be amended to increase the scope of such permitted indemnification, against any and all Indemnifiable Claims and Indemnifiable Losses; provided, however, that,
except as provided in Sections 5, 8 and 20, Indemnitee shall not be entitled to indemnification or advancement of expenses pursuant to this Agreement in connection with any Claim initiated by Indemnitee against the Company or any director or
officer of the Company unless the Company has joined in or consented to the initiation of such Claim. 
 3. Advancement of
Expenses. Indemnitee shall have the right to advancement by the Company prior to the final disposition of any Indemnifiable Claim of any and all Expenses relating to any Indemnifiable Claim paid or actually incurred by Indemnitee or which are
reasonably likely to be paid or actually incurred by Indemnitee. Indemnitee’s right to such advancement is not subject to the satisfaction of any standard of conduct. Without limiting the generality or effect of the foregoing, within five
business days after any request by Indemnitee, the Company shall, in accordance with such request, (a) pay such Expenses on behalf of Indemnitee, (b) advance to Indemnitee funds in an amount sufficient to pay such Expenses, or
(c) reimburse Indemnitee for such Expenses; provided that Indemnitee shall repay, without interest, any amounts actually advanced to Indemnitee that, at the final disposition of the Indemnifiable Claim to which the advance related, were
in excess of amounts paid or payable by Indemnitee in respect of Expenses relating to such Indemnifiable Claim. In connection with any such payment, advancement or reimbursement, Indemnitee shall execute and deliver to the Company an undertaking,
which need not be secured and shall be accepted without reference to Indemnitee’s ability to repay the Expenses, to (i) repay any amounts paid, advanced, or reimbursed by the Company in respect of Expenses that, at the final disposition of
the Indemnifiable Claim to which such payment, advance or reimbursement related, were in excess of amounts paid or payable by Indemnitee in respect of Expenses relating to such Indemnifiable Claim, and (ii) repay any and all amounts paid,
advanced, or reimbursed by the Company in respect of Expenses if Indemnitee shall have been determined, pursuant to Section 7, not to be entitled to indemnification hereunder.

 4. Intentionally Omitted. 

5. Partial Indemnity. If Indemnitee is entitled under any provision of this Agreement to indemnification by the Company for some
or a portion of any Indemnifiable Loss but not for all of the total amount thereof, the Company shall nevertheless indemnify Indemnitee for the portion thereof to which Indemnitee is entitled. 

6. Procedure for Notification. To obtain indemnification under this Agreement in respect of an Indemnifiable Loss, Indemnitee
shall submit to the Company a written request therefor, including a brief description (based upon information then available to Indemnitee) of such Indemnifiable Loss. If, at the time of the receipt of such request, the Company has directors’
and officers’ liability insurance in effect under which coverage for such Indemnifiable Loss is potentially available, the Company shall give prompt written notice of such Indemnifiable Loss to the applicable insurers in accordance with the
procedures set forth in the applicable policies. The Company shall provide to Indemnitee a copy of such notice delivered to the applicable insurers, and copies of all subsequent correspondence between the Company and such insurers regarding the
Indemnifiable Loss, in each case substantially concurrently with the delivery or receipt thereof by the Company. The failure by Indemnitee to timely notify the Company of any Indemnifiable Loss shall not relieve the Company from any liability
hereunder unless, and only to the extent that, the Company did not otherwise learn of such Indemnifiable Loss and such failure results in forfeiture by the Company of substantial defenses, rights or insurance coverage. 

7. Determination of Right to Indemnification. 
 (a) To the extent that Indemnitee shall have been successful on the merits or otherwise in defense of any Indemnifiable Claim or any portion thereof or in defense of any issue or matter therein, including
without limitation dismissal without prejudice, Indemnitee shall be indemnified against all Indemnifiable Losses relating to such Indemnifiable Claim or any portion thereof in accordance with Section 2 and no Standard of Conduct Determination
(as defined in Section 7(b)) shall be required. 
 (b) To the extent that the provisions of Section 7(a) are
inapplicable to an Indemnifiable Claim that shall have been finally disposed of, any determination of whether Indemnitee has satisfied any applicable standard of conduct under Delaware law that is a legally required condition to indemnification of
Indemnitee hereunder against Indemnifiable Losses relating to such Indemnifiable Claim (a “Standard of Conduct Determination”) shall be made as follows: (i) prior to the occurrence of any Change of Control, (A) by a
majority vote of the Disinterested Directors, even if less than a quorum of the Board, or (B) if there are no such Disinterested Directors, by Independent Counsel in a written opinion addressed to the Board, a copy of which shall be delivered
to Indemnitee; and (ii) if a Change in Control shall has occurred, by Independent Counsel in a written opinion addressed to the Board, a copy of which shall be delivered to Indemnitee. The Company shall indemnify and hold harmless Indemnitee
against and, if requested by Indemnitee, shall reimburse Indemnitee for, or advance to Indemnitee, within five business days of such request, any and all reasonable costs and expenses (including attorneys’ and experts’ fees and expenses)
actually incurred by Indemnitee in cooperating with the person or persons making such Standard of Conduct Determination. 
 (c)
The Company shall use its reasonable best efforts to cause any Standard of Conduct Determination required under Section 7(b) to be made as promptly as practicable. If the person or persons determined under Section 7 to make the Standard of
Conduct Determination shall not have made a determination within 30 days after the later of (A) receipt by the Company of written notice from Indemnitee advising the Company of the final disposition of the applicable Indemnifiable Claim
(the date of such receipt being the “Notification Date”) and (B) the selection of an Independent Counsel, if such determination is to be made by Independent Counsel, then Indemnitee shall be deemed to have satisfied the
applicable standard of conduct; provided that such 30-day period may be extended for a reasonable time, not to exceed an additional 30 days, if the person or persons making such determination in good faith requires such additional time
to obtain or evaluate information relating thereto.

 (d) If (i) Indemnitee shall be entitled to indemnification pursuant to
Section 7(a), (ii) no determination of whether Indemnitee has satisfied any applicable standard of conduct under Delaware law is a legally required condition to indemnification of Indemnitee hereunder against any Indemnifiable Losses, or
(iii) Indemnitee has been determined or deemed pursuant to Section 7(b) or (c) to have satisfied any applicable standard of conduct under Delaware law which is a legally required condition to indemnification of Indemnitee then the
Company shall pay to Indemnitee, within five business days after the later of (x) the Notification Date regarding the Indemnifiable Claim giving rise to the Indemnifiable Losses and (y) the earliest date on which the applicable criterion
specified in clause (i), (ii) or (iii) is satisfied, an amount equal to such Indemnifiable Losses. 
 (e) If a
Standard of Conduct Determination is to be made by Independent Counsel pursuant to Section 7(b)(i), the Independent Counsel shall be selected by the Board of Directors, and the Company shall give written notice to Indemnitee advising him or her
of the identity of the Independent Counsel so selected. If a Standard of Conduct Determination is to be made by Independent Counsel pursuant to Section 7(b)(ii), the 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. In either case, Indemnitee or the Company, as applicable, may, within five business days after receiving written notice of selection from the other,
deliver to the other 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 satisfy the criteria set forth in the definition of
“Independent Counsel” in Section 1(h), and the objection shall set forth with particularity the factual basis of such assertion. Absent a proper and timely objection, the person or firm so selected shall act as Independent Counsel. If
such written objection is properly and timely made and substantiated, (i) the Independent Counsel so selected may not serve as Independent Counsel unless and until such objection is withdrawn or a court has determined that such objection is
without merit and (ii) the non-objecting party may, at its option, select an alternative Independent Counsel and give written notice to the other party advising such other party of the identity of the alternative Independent Counsel so
selected, in which case the provisions of the two immediately preceding sentences and clause (i) of this sentence shall apply to such subsequent selection and notice. If applicable, the provisions of clause (ii) of the immediately
preceding sentence shall apply to successive alternative selections. If no Independent Counsel that is permitted under the foregoing provisions of this Section 7(e) to make the Standard of Conduct Determination shall have been selected within
30 days after the Company gives its initial notice pursuant to the first sentence of this Section 7(e) or Indemnitee gives its initial notice pursuant to the second sentence of this Section 7(e), as the case may be, either the Company
or Indemnitee may petition the Court of Chancery of the State of Delaware 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 or firm with respect to whom all objections are so resolved or the person or firm so appointed will act as Independent
Counsel. In all events, the Company shall pay all of the reasonable fees and expenses of the Independent Counsel incurred in connection with the Independent Counsel’s determination pursuant to Section 7(b). 

8. Presumption of Entitlement. 
 (a) In making any Standard of Conduct Determination, the person or persons making such determination shall presume that Indemnitee has satisfied the applicable standard of conduct, and the Company may
overcome such presumption only by its adducing clear and convincing evidence to the contrary. Any Standard of Conduct Determination that is adverse to Indemnitee may be challenged by the Indemnitee in the Court of Chancery of the State of Delaware.
If Indemnitee makes such challenge of the Standard of Conduct Determination, the Company shall be obligated to indemnify and advance the Indemnitee the costs of such challenge; provided, however that the Indemnitee shall repay, without
interest, any amounts actually advanced to Indemnitee for such challenge if such challenge is unsuccessful. No determination by the Company (including by its directors or any Independent Counsel) that Indemnitee has not satisfied any applicable
standard of conduct shall be a defense to any Claim by Indemnitee for indemnification or reimbursement or advance payment of Expenses by the Company hereunder or create a presumption that Indemnitee has not met any applicable standard of conduct.

 9. No Other Presumption. For purposes of this Agreement, the termination of any Claim by judgment, order, settlement
(whether with or without court approval) or conviction, or upon a plea of nolo contendere or its equivalent, will not create a presumption that Indemnitee did not meet any applicable standard of conduct or that indemnification hereunder is
otherwise not permitted.

 10. Non-Exclusivity. The rights of Indemnitee hereunder will be in addition to any
other rights Indemnitee may have under the Constituent Documents, or the substantive laws of the Company’s jurisdiction of incorporation, any other contract or otherwise (collectively, “Other Indemnity Provisions”);
provided, however, that (a) to the extent that Indemnitee otherwise would have any greater right to indemnification under any Other Indemnity Provision, Indemnitee will be deemed to have such greater right hereunder and
(b) to the extent that any change is made to any Other Indemnity Provision which permits any greater right to indemnification than that provided under this Agreement as of the date hereof, Indemnitee will be deemed to have such greater right
hereunder. The Company will not adopt any amendment to any of the Constituent Documents the effect of which would be to deny, diminish or encumber Indemnitee’s right to indemnification under this Agreement. 

11. Liability Insurance and Funding. For the duration of Indemnitee’s service as a director and/or officer of the Company,
and thereafter for so long as Indemnitee shall be subject to any pending or possible Indemnifiable Claim, the Company shall use commercially reasonable efforts (taking into account the scope and amount of coverage available relative to the cost
thereof) to cause to be maintained in effect policies of directors’ and officers’ liability insurance providing coverage for directors and/or officers of the Company that is at least substantially comparable in scope and amount to that
provided by the Company’s current policies of directors’ and officers’ liability insurance. The Company shall provide Indemnitee with a copy of all directors’ and officers’ liability insurance applications, binders,
policies, declarations, endorsements and other related materials, and shall provide Indemnitee with a reasonable opportunity to review and comment on the same. Without limiting the generality or effect of the two immediately preceding sentences, the
Company shall not discontinue or significantly reduce the scope or amount of coverage from one policy period to the next (i) without the prior approval thereof by a majority vote of the Incumbent Directors, even if less than a quorum, or
(ii) if at the time that any such discontinuation or significant reduction in the scope or amount of coverage is proposed there are no Incumbent Directors, without the prior written consent of Indemnitee (which consent shall not be unreasonably
withheld or delayed). In all policies of directors’ and officers’ liability insurance obtained by the Company, Indemnitee shall be named as an insured in such a manner as to provide Indemnitee the same rights and benefits, subject to the
same limitations, as are accorded to the Company’s directors and officers most favorably insured by such policy. The Company may, but shall not be required to, create a trust fund, grant a security interest or use other means, including without
limitation a letter of credit, to ensure the payment of such amounts as may be necessary to satisfy its obligations to indemnify and advance expenses pursuant to this Agreement. 

12. Subrogation. In the event of payment under this Agreement, the Company shall be subrogated to the extent of such payment to
all of the related rights of recovery of Indemnitee against other persons or entities (other than Indemnitee’s successors), including any entity or enterprise referred to in clause (i) of the definition of “Indemnifiable Claim”
in Section 1(f). Indemnitee shall execute all papers reasonably required to evidence such rights (all of Indemnitee’s reasonable Expenses, including attorneys’ fees and charges, related thereto to be reimbursed by or, at the option of
Indemnitee, advanced by the Company). 
 13. No Duplication of Payments. The Company shall not be liable under this
Agreement to make any payment to Indemnitee in respect of any Indemnifiable Losses to the extent Indemnitee has otherwise actually received payment (net of Expenses incurred in connection therewith) under any insurance policy, the Constituent
Documents and Other Indemnity Provisions or otherwise. 
 14. Defense of Claims. The Company shall be entitled to
participate in the defense of any Indemnifiable Claim or to assume the defense thereof, with counsel reasonably satisfactory to the Indemnitee; provided that if Indemnitee reasonably believes, after consultation with counsel selected by
Indemnitee, that (a) the use of counsel chosen by the Company to represent Indemnitee would present such counsel with an actual or potential conflict, (b) the named parties in any such Indemnifiable Claim (including any impleaded parties)
include both the Company and Indemnitee and that there may be one or more legal defenses available to Indemnitee that are different from or in addition to those available to the Company, or (c) any such representation by such counsel would be
precluded under the applicable standards of professional conduct then prevailing, then Indemnitee shall be entitled to retain separate counsel (but not more than one law firm plus, if applicable, local counsel in respect of any particular
Indemnifiable Claim) at the Company’s expense. The Company shall not be liable to Indemnitee under this Agreement for any amounts paid in settlement of any threatened or pending Indemnifiable Claim effected without the Company’s prior
written consent. The Company shall not, without the prior written consent of the Indemnitee, effect any settlement of any threatened or pending Indemnifiable Claim which the Indemnitee is or could have been a party unless such settlement solely
involves the payment of money and includes a complete and unconditional release of the Indemnitee from all liability on any claims that are the subject matter of such Indemnifiable Claim. Neither the Company nor Indemnitee shall unreasonably
withhold its consent to any proposed settlement; provided that Indemnitee may withhold consent to any settlement that does not provide a complete and unconditional release of Indemnitee.

 15. Successors and Binding Agreement. 

(a) This Agreement shall be binding upon and inure to the benefit of the Company and any successor to the Company, including without
limitation any person acquiring directly or indirectly all or substantially all of the business or assets of the Company whether by purchase, merger, consolidation, reorganization or otherwise (and such successor will thereafter be deemed the
“Company” for purposes of this Agreement), but shall not otherwise be assignable or delegatable by the Company. 
 (b) This Agreement shall inure to the benefit of and be enforceable by the Indemnitee’s personal or legal representatives, executors, administrators, heirs, distributees, legatees and other
successors. 
 (c) This Agreement is personal in nature and neither of the parties hereto shall, without the consent of the
other, assign or delegate this Agreement or any rights or obligations hereunder except as expressly provided in Sections 15(a) and 15(b). Without limiting the generality or effect of the foregoing, Indemnitee’s right to receive payments
hereunder shall not be assignable, whether by pledge, creation of a security interest or otherwise, other than by a transfer by the Indemnitee’s will or by the laws of descent and distribution, and, in the event of any attempted assignment or
transfer contrary to this Section 15(c), the Company shall have no liability to pay any amount so attempted to be assigned or transferred. 
 16. Notices. For all purposes of this Agreement, all communications, including without limitation notices, consents, requests or approvals, required or permitted to be given hereunder shall be in
writing and shall be deemed to have been duly given when hand delivered or dispatched by electronic facsimile transmission (with receipt thereof orally confirmed), or five business days after having been mailed by United States registered or
certified mail, return receipt requested, postage prepaid or one business day after having been sent for next-day delivery by a nationally recognized overnight courier service, addressed to the Company (to the attention of the Secretary of the
Company) and to Indemnitee at the addresses shown on the signature page hereto, or to such other address as any party may have furnished to the other in writing and in accordance herewith, except that notices of changes of address will be effective
only upon receipt. 
 17. Governing Law. The validity, interpretation, construction and performance of this Agreement
shall be governed by and construed in accordance with the substantive laws of the State of Delaware, without giving effect to the principles of conflict of laws of such State. The Company and Indemnitee each hereby irrevocably consent to the
jurisdiction of the Chancery Court of the State of Delaware for all purposes in connection with any action or proceeding which arises out of or relates to this Agreement and agree that any action instituted under this Agreement shall be brought only
in the Chancery Court of the State of Delaware. 
 18. Validity. If any provision of this Agreement or the application of
any provision hereof to any person or circumstance is held invalid, unenforceable or otherwise illegal, the remainder of this Agreement and the application of such provision to any other person or circumstance shall not be affected, and the
provision so held to be invalid, unenforceable or otherwise illegal shall be reformed to the extent, and only to the extent, necessary to make it enforceable, valid or legal. In the event that any court or other adjudicative body shall decline to
reform any provision of this Agreement held to be invalid, unenforceable or otherwise illegal as contemplated by the immediately preceding sentence, the parties thereto shall take all such action as may be necessary or appropriate to replace the
provision so held to be invalid, unenforceable or otherwise illegal with one or more alternative provisions that effectuate the purpose and intent of the original provisions of this Agreement as fully as possible without being invalid, unenforceable
or otherwise illegal. 
 19. Miscellaneous. No provision of this Agreement may be waived, modified or discharged unless
such waiver, modification or discharge is agreed to in writing signed by Indemnitee and the Company. No waiver by either party hereto at any time of any breach by the other party hereto or compliance with any condition or provision of this Agreement
to be performed by such other party shall be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or subsequent time. No agreements or representations, oral or otherwise, expressed or implied with respect to
the subject matter hereof have been made by either party that are not set forth expressly in this Agreement. References to Sections are to references to Sections of this Agreement.

 20. Legal Fees and Expenses. Without limiting the generality or effect of any other
provision hereof, but subject to Section 8, if it should appear to Indemnitee that the Company has failed to comply with any of its obligations under this Agreement or in the event that the Company or any other person takes or threatens to take
any action to declare this Agreement void or unenforceable, or institutes any litigation or other action or proceeding designed to deny, or to recover from, Indemnitee the benefits provided or intended to be provided to Indemnitee hereunder, the
Company irrevocably authorizes the Indemnitee from time to time to retain counsel of Indemnitee’s choice, at the expense of the Company as hereafter provided, to advise and represent Indemnitee in connection with any such interpretation,
enforcement or defense, including without limitation the initiation or defense of any litigation or other legal action, whether by or against the Company or any director, officer, stockholder or other person affiliated with the Company, in any
jurisdiction. Without respect to whether Indemnitee prevails, in whole or in part, in connection with any of the foregoing, the Company will pay and be solely financially responsible for any and all attorneys’ and related fees and expenses
incurred by Indemnitee in connection with any of the foregoing. 
 21. Certain Interpretive Matters. No provision of this
Agreement shall be interpreted in favor of, or against, either of the parties hereto by reason of the extent to which any such party or its counsel participated in the drafting thereof or by reason of the extent to which any such provision is
inconsistent with any prior draft hereof or thereof. 
 22. Counterparts. This Agreement may be executed in one or more
counterparts, each of which will be deemed to be an original but all of which together shall constitute one and the same agreement.
