Form of Amended and Restated Indemnification Agreement



 EXHIBIT 10.4 

[AMENDED AND RESTATED]1 INDEMNIFICATION AGREEMENT 
 This [Amended and Restated] Indemnification Agreement (“Agreement”) is made as of              by and between Imperva,
Inc., a Delaware corporation (the “Company”), and              (“Indemnitee”). 

RECITALS 

WHEREAS, the Company desires to attract and retain the services of highly qualified individuals, such as Indemnitee, to serve the Company
and its Subsidiaries and Enterprises (each as defined below); 
 WHEREAS, in order to induce Indemnitee to provide or continue
to provide services to the Company and/or its Subsidiaries or Enterprises, the Company wishes to provide for the indemnification of, and advancement of expenses to, Indemnitee to the maximum extent permitted by law; 

WHEREAS, the Bylaws (as the same may be amended, restated or otherwise modified from time to time, the “Bylaws”) of the
Company require indemnification of the executive 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 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 and executive officers 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, prudent and necessary for
the Company contractually to obligate itself to indemnify, and to advance expenses on behalf of, the executive officers and directors of the Company to the fullest extent permitted by applicable law, regardless of any amendment or revocation of the
Certificate of Incorporation (as the same may be amended, restated or otherwise modified from time to time, 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 Bylaws and any resolutions adopted pursuant thereto, and shall not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder[.] [; and] 

  
  

	1 	 Note: to amend and restate for directors with agreements in place. 










 [WHEREAS, Indemnitee has certain rights to indemnification and/or
insurance provided by [Name of Fund/Sponsor] which Indemnitee and [Name of Fund/Sponsor] intend to be secondary to the primary obligation of the Company to indemnify Indemnitee as provided in this Agreement, with the Company’s acknowledgment
and agreement to the foregoing being a material condition to Indemnitee’s willingness to serve or continue to serve on the Board.]2 
 NOW, THEREFORE, in consideration of the premises and the covenants contained herein, the Company and Indemnitee do hereby covenant and agree as follows: 

Section 1. Services to the Company. Indemnitee agrees to serve and/or continue to serve as an Indemnifiable Person in the
capacity or capacities in which Indemnitee currently serves the Company as an Indemnifiable Person, and any additional capacity in which Indemnitee may agree to serve, until such time as Indemnitee’s service in a particular capacity shall end
according to the terms of an agreement, the Company’s Charter or Bylaws, governing law, or otherwise. Nothing contained in this Agreement is intended to create any right to continued employment or other form of service for the Company or a
Subsidiary or Enterprise of the Company by Indemnitee. 
 Section 2. Definitions. 

As used in this Agreement: 
 (a) “Change in Control” shall mean (i) any “person” (as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended), other than a
Subsidiary or a trustee or other fiduciary holding securities under an employee benefit plan of the Company or Subsidiary, who becomes the “beneficial owner” (as defined in Rule 13d-3 under said Act), directly or indirectly, of
securities of the Company representing 20% or more of the total voting power represented by the Company’s then outstanding capital stock; (ii) during any period of two (2) consecutive years, individuals who at the beginning of such
period constitute the Board of Directors and any new director whose election by the Board of Directors or nomination for election by the Company’s stockholders was approved by a vote of at least two-thirds (2/3) of the directors then still in office who either were directors at the beginning of the period or whose election or
nomination for election was previously so approved, cease for any reason to constitute a majority thereof; or (iii) the stockholders of the Company approve a merger or consolidation of the Company with any other corporation, other than a merger
or consolidation that would result in the outstanding capital stock of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into capital stock of the surviving entity) at
least 80% of the total voting power represented by the capital stock of the Company or such surviving entity outstanding immediately after such merger or consolidation, or the stockholders of the Company approve a plan of complete liquidation of the
Company or an agreement for the sale or disposition by the Company (in one transaction or a series of transactions) of all or substantially all of the Company’s assets.

 (b) “Enterprise” shall mean any corporation (other than the Company),
partnership, joint venture, trust, employee benefit plan, limited liability company or other legal entity of which Indemnitee is, was or will be serving at the request, election or direction of the Company as a director, manager, officer, employee,
agent, trustee, member, partner, agent, attorney, consultant, member of the entity’s governing body, fiduciary or in any other similar capacity. 
 (c) “Expenses” shall mean all direct and indirect costs of any type or nature whatsoever (including, without limitation, all attorneys’ fees and related disbursements, and other
out-of-pocket costs), paid or incurred by Indemnitee in connection with either the investigation, defense or appeal of, or being a witness in a Proceeding (as defined below), or establishing or enforcing a right to indemnification under this
Agreement, the DGCL or otherwise; provided, however, that Expenses shall not include any judgments, fines, ERISA excise taxes or penalties or amounts paid in settlement of a Proceeding. 

(d) “Indemnifiable Event” means any event or occurrence related to Indemnitee’s service for the Company or any
Subsidiary or Enterprise as an Indemnifiable Person, or by reason of anything done or not done, or any act or omission, by Indemnitee in any such capacity. 
 (e) “Indemnifiable Person” means any person who is or was a director, officer, employee, attorney, trustee, manager, member, partner, consultant, member of an entity’s governing body
(whether constituted as a board of directors, board of managers, general partner or otherwise) or other agent or fiduciary of the Company or a Subsidiary or Enterprise of the Company. 

(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 performing, nor in the five (5) years preceding the time in question has performed services for: (i) the Company, any Subsidiary, any Enterprise or
Indemnitee; 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. 

(g) “Other Liabilities” means any and all liabilities of any type whatsoever (including, but not limited to, judgments,

penalties, ERISA (or other benefit plan related) excise taxes or penalties, or amounts paid in settlement). 
 (h) The term
“Proceeding” shall include any threatened, pending or completed action, suit, arbitration, alternate dispute resolution mechanism, investigation, inquiry, 

  
 3 








 
administrative hearing or any other actual, threatened or completed proceeding, whether brought in the right of the Company or otherwise and whether civil, criminal, administrative, regulatory,
investigative or any other type whatsoever, and whether formal or informal, and including any appeal thereof. 
 (i)
“Subsidiary” means any corporation of which more than 50% of the outstanding voting securities is owned directly or indirectly by the Company. 
 Section 3. Agreement to Indemnify. In the event Indemnitee is a person who was or is a party to or witness in or is threatened to be made a party to or witness in or otherwise involved in any
Proceeding by reason of an Indemnifiable Event, the Company shall indemnify Indemnitee from and against any and all Expenses and Other Liabilities incurred by Indemnitee in connection with (including in preparation for) such Proceeding to the
fullest extent not prohibited by the provisions of the Charter, the Bylaws and the DGCL, as the same may be amended from time to time (but only to the extent that such amendment permits the Company to provide broader indemnification rights than the
Charter, the Bylaws or the DGCL permitted prior to the adoption of such amendment). 
 Section 4. Partial
Indemnification. If Indemnitee is entitled under any provision of this Agreement to indemnification by the Company for some or a portion of any Expenses or Other Liabilities but not entitled, however, to indemnification for the total amount of
such Expenses or Other Liabilities, the Company shall nevertheless indemnify Indemnitee for such total amount except as to the portion thereof to which indemnification is prohibited by the provisions of the Charter, Bylaws or the DGCL. In any review
or Proceeding to determine the extent of indemnification, the Company shall bear the burden to establish, by clear and convincing evidence, the lack of a successful resolution of a particular claim, issue or matter and which amounts sought in
indemnity are allocable to claims, issues or matters which were not successfully resolved. 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 5. 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 such amounts have been paid directly to Indemnitee (or paid directly to
a third party on Indemnitee’s behalf) under any insurance policy, contract, agreement or otherwise[; provided that the foregoing shall not affect the rights of Indemnitee or the Fund Indemnitors as set forth in Section 11(c)]; 

(b) to indemnify Indemnitee 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; 

  
 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, as required in each case pursuant to Section 304 of the Sarbanes-Oxley Act of 2002
(“SOX”) or the payment to the Company of profits arising from the purchase and sale by Indemnitee of securities in violation of Section 306 of SOX); 
 (d) to indemnify or advance Expenses to Indemnitee with respect to any Proceeding, or part thereof, brought voluntarily by Indemnitee (and not by way of defense) except (i) where the Board has
consented to the initiation of such Proceeding or part thereof, (ii) with respect to Proceedings brought to establish or enforce a right to indemnification under this Agreement, any other statute or law, as permitted under the DGCL, or
otherwise, or (iii) with respect to Proceedings brought to discharge Indemnitee’s fiduciary responsibilities, whether under ERISA or otherwise, but such indemnification or advancement of Expenses may be provided by the Company in specific
cases if the Board finds it to be appropriate; provided, however, that nothing in this Section 7(d) shall prevent Indemnitee from asserting counterclaims or affirmative defenses in an action brought against Indemnitee; or

 (e) to indemnify Indemnitee for Other Liabilities if such indemnification is prohibited by applicable law (as such law exists
at the time indemnification would otherwise be required pursuant to this Agreement). 
 Section 6. Advancement of
Expenses. The Company shall advance all Expenses actually and reasonably incurred by Indemnitee in connection with (including in preparation for) any Proceeding related to an Indemnifiable Event, and such advancement shall be made within thirty
(30) days after the receipt by the Company of a statement or statements requesting such advances (which shall include invoices received by Indemnitee in connection with such Expenses but, in the case of invoices in connection with legal
services, any references to legal work performed or to expenditures made that would cause Indemnitee to waive any privilege accorded by applicable law shall not be included with the invoice) from time to time, whether prior to or after final
disposition of any Proceeding. Advances shall be unsecured and interest free. Advances shall be made without regard to Indemnitee’s ability to repay the expenses and without regard to Indemnitee’s ultimate entitlement to indemnification
under the other provisions of this Agreement. Indemnitee hereby undertakes to repay such amounts advanced if, and only if and to the extent that, it shall ultimately be determined that Indemnitee is not entitled to be indemnified by the Company
under the provisions of this Agreement, the Charter, the Bylaws or the DGCL. The right to advances under this paragraph shall in all events continue until final disposition of any Proceeding, including any appeal therein. 

Section 7. Procedure for Notification and Defense of Claim. 

(a) Promptly following the time that Indemnitee has notice of the commencement of or the threat of commencement of any Proceeding,
Indemnitee shall, if Indemnitee believes that indemnification or advancement of Expenses with respect thereto may be sought from the Company under this Agreement, notify the Company of the commencement or threat of commencement thereof, and shall
provide the Company with all documentation 

  
 5 








 
related thereto as reasonably requested by the Company. The failure of Indemnitee to so notify the Company shall not relieve the Company of any obligation which it may have to Indemnitee under
this Agreement or otherwise except to the extent that the Company is materially prejudiced in its defense of such Proceeding as a result of such failure. 
 (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, 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. Such defense by the Company
may include the representation of two or more parties by one attorney or law firm as permitted under the ethical rules and legal requirements related to joint representations. 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 reasonable 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 or otherwise for any amounts paid in
settlement of any Proceeding effected without its prior written consent (which consent shall not be unreasonably withheld or delayed); provided, however, that if a Change in Control has occurred, the Company shall be liable for indemnification of
Indemnitee for amounts paid in settlement if the Independent Counsel has approved the settlement. Neither the Company nor any Subsidiary or Enterprise of the Company shall, without the prior written consent of Indemnitee (which consent shall not be
unreasonably withheld or delayed), enter into a settlement of any Proceeding that might result in the imposition of any Expense, Other Liability, penalty, limitation or detriment on Indemnitee, whether indemnifiable under this Agreement or
otherwise, including 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, 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 8. Procedure Upon Application for Indemnification. 

(a) To the extent that Indemnitee shall have been successful on the merits in any Proceeding to which it is a party or a participant or
in defense of any claim, issue or matter therein, the Company shall indemnify Indemnitee against Expenses, and no determination shall be required to be made with respect to Indemnitee’s entitlement to indemnification hereunder. The Company also
shall indemnify Indemnitee if he or she has not failed to meet the applicable standard of conduct for indemnification. In cases where the first sentence of this Section 8(a) is inapplicable, a determination with respect to Indemnitee’s
entitlement to indemnification hereunder shall be made in the specific case by one of the following methods which shall be at the election of Indemnitee, in his sole discretion: (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) by Independent Counsel selected by Indemnitee and approved by the
Board of Directors (which approval may not be unreasonably withheld or delayed) in a written opinion to the Board. If Indemnitee is an officer or director of the Company at the time that Indemnitee is making his or her election, then Indemnitee
shall not select Independent Counsel to make the determination unless there are no disinterested directors or unless the disinterested directors agree to the selection of Independent Counsel. The selected forum shall be referred to herein as the
“Reviewing Party.” Notwithstanding the foregoing, following any Change in Control, the Reviewing Party shall be Independent Counsel selected in the manner provided above in this Section 8(a). For purposes hereof, disinterested
directors are those members of the Board who are not parties to the Proceeding in respect of which indemnification is sought. In the case that the Reviewing Party is the 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 to the extent any such amounts have not been previously
advanced by the Company. As soon as practicable, and in no event later than thirty (30) days after receipt by the Company of written notice of Indemnitee’s choice of forum pursuant to this Section 8(a), the Company and Indemnitee
shall each submit to the Reviewing Party such information as they believe is appropriate for the Reviewing Party to consider. The Reviewing Party shall arrive at its decision within a reasonable period of time following the receipt of all such
information from the Company and Indemnitee, but in no event later than thirty (30) days following the receipt of all such information, provided that the time by which the Reviewing Party must reach a decision may be extended by mutual
agreement of the Company and Indemnitee. 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 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. Further, the Company agrees to pay the reasonable fees and
expenses of the Independent Counsel. 
 (b) The Company shall indemnify Indemnitee against all Expenses incurred by Indemnitee
in connection with any hearing or Proceeding under this Section 8 involving Indemnitee, and against all Expenses incurred by Indemnitee in connection with any other Proceeding between the Company and Indemnitee involving the interpretation or
enforcement of the rights of Indemnitee under this Agreement unless a court of competent jurisdiction finds that 

  
 7 








 
each of the material claims of Indemnitee in any such Proceeding was frivolous or made in bad faith . 
 Section 9. 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, 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.

 (d) Indemnitee shall be deemed to have acted in good faith if Indemnitee’s action is based on the records or books of
account of the Company, including financial statements, or on information supplied to Indemnitee by the officers of the Company in the course of their duties, or on the advice of legal counsel for the Company or on information or records given or
reports made to the Company by an independent certified public accountant or by an appraiser or other expert selected by the Company. Whether or not the foregoing provisions of this Section 9(d) are satisfied, it shall in any event be presumed
that Indemnitee has at all times acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Company or, with respect to any criminal Proceeding, that Indemnitee had reasonable cause to believe
that his conduct was unlawful. Anyone seeking to overcome this presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence. 
 (e) The Company acknowledges that a settlement or other disposition short of final judgment may be successful if it permits a party to avoid expense, delay, distraction, disruption and uncertainty. In the
event that any Proceeding to which Indemnitee is a party is 

  
 8 








 
resolved in any manner other than by adverse judgment against Indemnitee (including, without limitation, settlement of such Proceeding with or without payment of money or other consideration), it
shall be presumed that Indemnitee has been successful on the merits or otherwise in such Proceeding. Anyone seeking to overcome this presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence.

 Section 10. Remedies of Indemnitee. 
 (a) Notwithstanding a final determination by any Reviewing Party that Indemnitee is not entitled to indemnification with respect to a specific Proceeding, Indemnitee shall be entitled to an adjudication
by the Delaware Court of his or her entitlement to such indemnification, as further described in Section 10(b). Indemnitee shall have the right to apply to the Delaware Court for the purpose of enforcing Indemnitee’s right to
indemnification pursuant to this Agreement. Further, the parties recognize that if any provision of this Agreement is violated by the Company, including with respect to compliance with the time periods specified herein, Indemnitee may be without an
adequate remedy at law. Accordingly, in the event of any such violation, Indemnitee shall be entitled, if Indemnitee so elects, to institute Proceedings, either in law or at equity, to obtain damages, to enforce specific performance, to enjoin such
violation, or to obtain any relief or any combination of the foregoing as Indemnitee may elect to pursue. 
 (b) In the event
that a final determination by any Reviewing Party that Indemnitee is not entitled to indemnification, any judicial proceeding commenced pursuant to this Section 10 shall be conducted in all respects as a de novo trial on the merits and
Indemnitee shall not be prejudiced by reason of that adverse determination. In any judicial proceeding commenced pursuant to this Section 10, the Company shall have the burden of proving Indemnitee is not entitled to indemnification or
advancement, as the case may be. 
 (c) The Company shall be precluded from asserting in any judicial proceeding commenced
pursuant to this Section 10 that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court that the Company is bound by all the provisions of this Agreement. 

(d) 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 11. Non-exclusivity; Insurance; [Primacy of
Indemnification;] 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. 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


  

	

 9 








 
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) So long as
Indemnitee shall continue to serve the Company or a Subsidiary or Enterprise of the Company as an Indemnifiable Person and thereafter so long as Indemnitee shall be subject to any possible claim or threatened, pending or completed Proceeding as a
result of an Indemnifiable Event, the Company shall use reasonable efforts to maintain in full force and effect for the benefit of Indemnitee as an insured an insurance policy or policies providing liability insurance for directors, managers,
officers, employees, agents or trustees of the Company or of any Subsidiary or Enterprise issued by one or more reputable insurers and having the policy amount and deductible deemed appropriate by the Board. 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 reasonable action to cause such insurers to pay, on behalf of Indemnitee, all amounts payable as a result of such Proceeding in accordance with the terms of such policies. The
purchase, establishment and maintenance of any such insurance or other arrangements shall not in any way limit or affect the rights and obligations of the Company or of Indemnitee under this Agreement except as expressly provided herein, and the
execution and delivery of this Agreement by the Company and Indemnitee shall not in any way limit or affect the rights and obligations of the Company or the other party or parties thereto under any such insurance or other arrangement. 

(c) [The Company hereby acknowledges that Indemnitee has certain rights to indemnification, advancement of expenses and/or insurance
provided by [Name of Fund/Sponsor] and certain of its affiliates (collectively, the “Fund Indemnitors”). The Company hereby agrees (i) that it is the indemnitor of first resort (i.e., its obligations to Indemnitee are
primary and any obligation of the Fund Indemnitors to advance expenses or to provide indemnification for the same expenses or liabilities incurred by Indemnitee are secondary), (ii) that it shall be required to advance the full amount of
expenses incurred by Indemnitee and shall be liable for the full amount of all Expenses and Other Liabilities to the extent legally permitted and as required by the terms of this Agreement and the Charter and/or Bylaws (or any other agreement
between the Company and Indemnitee), without regard to any rights Indemnitee may have against the Fund Indemnitors, and (iii) that it irrevocably waives, relinquishes and releases the Fund Indemnitors from any and all claims against the Fund
Indemnitors for contribution, subrogation or any other recovery of any kind in respect thereof. The Company further agrees that no advancement or payment by the Fund Indemnitors on behalf of Indemnitee with respect to any claim for which Indemnitee
has sought indemnification from the Company shall affect the foregoing and the Fund Indemnitors shall have a right of contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of recovery of Indemnitee
against the 

  
 10 









 
Company. The Company and Indemnitee agree that the Fund Indemnitors are express third party beneficiaries of the terms of this Section 11(c).] 

(d) [Except as provided in paragraph (c) above,] [I/i]n 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 [(other than against the Fund Indemnitors)], 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. 
 (e) [Except as provided in
paragraph (c) above,] [T/t]he 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, 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 12. Survival of Rights; Successors and Assigns. The rights conferred on Indemnitee by this Agreement shall continue after Indemnitee has ceased to serve the Company or a Subsidiary or
Enterprise as an Indemnifiable Person and shall inure to the benefit of Indemnitee and his or her heirs, executors and administrators. This Agreement shall be binding upon the Company and its successors and assigns . 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 13. 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 14. 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 or officer of the Company, and the Company 

  
 11 









 
acknowledges that Indemnitee is relying upon this Agreement in serving as a director or 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.

Section 17. 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 Proceeding in such proportion as is deemed fair and reasonable in light of all of the circumstances in order to reflect (i) the relative benefits received by the Company and
Indemnitee in connection with the event(s) and/or transaction(s) giving rise to such Proceeding; and/or (ii) the relative fault of the Company (and its directors, officers, employees and agents) and Indemnitee in connection with such event(s)
and/or transactions.

to comply with the Indemnification exception under Section 1.409A-1(b)(10) of the regulations promulgated under the Internal Revenue Code of 1986, as amended (the “Code”), which provides that indemnification of, or the purchase
of an insurance policy providing for payments of, all or part of the expenses incurred or damages paid or payable by the Indemnitee with respect to a bona fide claim against the 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 the Indemnitee in his capacity as a service provider of the Company. The parties intend that this Agreement be interpreted and
construed with such intent. 
 Section 19. Applicable Law and Consent to Jurisdiction. This Agreement and the legal
relations among the parties shall be governed by, and construed and enforced in accordance with, the laws of the State of Delaware, without regard to its conflict of laws rules. The Company and Indemnitee hereby irrevocably and unconditionally

country, (ii) consent to submit to the exclusive jurisdiction of the Delaware Court for purposes of any action or proceeding arising out of or in connection with this Agreement, (iii) consent to service of process at the address set forth
in Section 16 of this Agreement with the same legal force and validity as if served upon such party personally within the State of Delaware, (iv) waive any objection to the laying of venue of any such action or proceeding in the Delaware
Court, and (v) waive, and agree not to plead or to make, any claim that any such action or proceeding brought in the Delaware Court has been brought in an improper or inconvenient forum.
