threatened to be made a party to any Proceeding (including a Proceeding by or in the right of the Company to procure a judgment in its favor) against all Liabilities and Expenses suffered or reasonably incurred (and, in the case of retainers,
reasonably expected to be incurred) by Indemnitee in connection with such Proceeding, including but not limited to: 

(a)        the fullest extent permitted by the provision of the DGCL that authorizes
or contemplates additional indemnification by agreement, or the corresponding provision of any amendment to or replacement of the DGCL; and 

(b)        the fullest extent authorized or permitted by any amendments to or
replacements of the DGCL adopted after the date of this Agreement that increase the extent to which a corporation may indemnify its officers and directors. 

Section 7.        Exclusions. Notwithstanding any provision in this
Agreement, the Company shall not be obligated under this Agreement to indemnify or hold harmless Indemnitee, or, in the case of (a) and (c), to advance Expenses to Indemnitee:

under any insurance policy obtained by the Company except with respect to any excess beyond the amount paid under such insurance policy; 

(b)        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 Exchange Act or similar provisions of state statutory law or common law; 

(c)        except as provided in Section 12(d) of this
Agreement, in connection with any Proceeding (or any part of any Proceeding) initiated by Indemnitee or, if Indemnitee was nominated to the Board by one of more of the Sponsor Entities, such Sponsor Entity, including any Proceeding (or any part of
any Proceeding) initiated by Indemnitee or, if Indemnitee was nominated to the Board by one or more of the Sponsor Entities, such Sponsor Entity, against the Company or its directors, officers, employees or other indemnitees, unless (i) the
Board authorized the Proceeding (or any part of any Proceeding) prior to its initiation, (ii) the Company provides the indemnification, in its sole discretion, pursuant to the powers vested in the Company under applicable law or (iii) such
Proceeding is being brought by Indemnitee to assert, interpret or enforce Indemnitee’s rights under this Agreement (for the avoidance of doubt, Indemnitee shall not be deemed, for purposes of this subsection, to have initiated or brought any
claim by reason of (A) having asserted any affirmative defenses in connection with a claim not initiated by Indemnitee or (B) having made any counterclaim (whether permissive or mandatory) in connection with any claim not initiated by
Indemnitee); or 
 (d)        if a final decision by a court having jurisdiction in
the matter that is not subject to appeal shall determine that such indemnification is not lawful. 

Section 8.        Advancement. In accordance with the pre-existing requirements of the Bylaws, and notwithstanding any provision of this Agreement to the contrary, the Company shall 

  
 5 







 
advance, to the extent not prohibited by applicable law, the Expenses and Liabilities reasonably incurred by Indemnitee in connection with any Proceeding, and such advancement shall be made
within thirty (30) days after the receipt by the Company of a statement or statements requesting such advances 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. Advances shall include any and all
Expenses reasonably incurred pursuing an action to enforce this right of advancement, including Expenses incurred preparing and forwarding statements to the Company to support the advances claimed. 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 repay the amounts advanced to the extent that it is ultimately determined by final judicial decision from which
there is no further right to appeal that the Indemnitee is not entitled to be indemnified by the Company. Nothing in this Section 8 shall limit Indemnitee’s right to advancement pursuant to
Section 12(d) of this Agreement. This Section 8 shall not apply to any claim made by Indemnitee for which indemnity is excluded pursuant to Sections 7(a) or
(c) hereof. 
 Section 9.        Procedure for Notification
and Defense of Claim. 
 (a)        Indemnitee shall promptly notify the
Company in writing of any Proceeding with respect to which Indemnitee intends to seek indemnification or advancement hereunder following the receipt by Indemnitee of written notice thereof (the date of such notification, the “Submission
Date”). The written notification to the Company shall include a description of the nature of the Proceeding and the facts underlying the Proceeding. To obtain indemnification under this Agreement, Indemnitee shall submit to the Company
a written request, including therein or therewith such documentation and information as is reasonably available to Indemnitee and is reasonably necessary to determine whether and to what extent Indemnitee is entitled to indemnification following the
final disposition of such Proceeding, including any appeal therein. Any delay or failure by Indemnitee to notify the Company hereunder will not relieve the Company from any liability which it may have to Indemnitee hereunder or otherwise than under
this Agreement, and any delay or failure in so notifying the Company shall not constitute a waiver by Indemnitee of any rights under this Agreement. The Secretary of the Company shall, promptly upon receipt of such a request for indemnification,
advise the Board in writing that Indemnitee has requested indemnification. 

(b)        In the event Indemnitee is entitled to indemnification and/or advancement
with respect to any Proceeding, Indemnitee may, at Indemnitee’s option, (i) retain counsel (including local counsel) selected by Indemnitee and approved by the Company to defend Indemnitee in such Proceeding, at the sole expense of the
Company (which approval shall not be unreasonably withheld, conditioned or delayed), or (ii) have the Company assume the defense of Indemnitee in such Proceeding, in which case the Company shall assume the defense of such Proceeding with
counsel selected by the Company and approved by Indemnitee (which approval shall not be unreasonably withheld, conditioned or delayed) within ten (10) days of the Company’s receipt of written notice of Indemnitee’s election to cause
the Company to do so. If the Company is required to assume the defense of any such Proceeding, it shall engage legal counsel for such defense, and the Company shall be solely responsible for all fees and expenses


  
 6 







 
of such legal counsel and otherwise of such defense. Such legal counsel may represent both Indemnitee and the Company (and any other party or parties entitled to be indemnified by the Company
with respect to such matter) unless, in the reasonable opinion of legal counsel to Indemnitee, there is a conflict of interest between Indemnitee and the Company (or any other such party or parties) or there are legal defenses available to
Indemnitee that are not available to the Company (or any such other party or parties). Notwithstanding either party’s assumption of responsibility for defense of a Proceeding, each party shall have the right to engage separate counsel at its
own expense. If the Company has responsibility for defense of a Proceeding, the Company shall provide the Indemnitee and its counsel with all copies of pleadings and material correspondence relating to the Proceeding. Indemnitee and the Company
shall reasonably cooperate in the defense of any Proceeding with respect to which indemnification is sought hereunder, regardless of whether the Company or Indemnitee assumes the defense thereof. Indemnitee may not settle or compromise any
Proceeding without the prior written consent of the Company, which consent shall not be unreasonably withheld, conditioned or delayed. The Company may not settle or compromise any Proceeding without the prior written consent of Indemnitee. 

Section 10.        Procedure Upon Application
for Indemnification. 
 (a)        Upon written request by Indemnitee for
indemnification pursuant to Section 9(a) hereof, if any determination by the Company is required by applicable law with respect to Indemnitee’s entitlement thereto, such determination shall be made (i) if
Indemnitee shall request such determination be made by Independent Counsel, by Independent Counsel, and (ii) in all other circumstances, (A) by a majority vote of the Disinterested Directors, even though less than a quorum of the Board,
(B) by a committee of Disinterested Directors designated by a majority vote of the Disinterested Directors, even though less than a quorum of the Board, (C) if there are no such Disinterested Directors or, if such Disinterested Directors
so direct, by Independent Counsel in a written opinion to the Board, a copy of which shall be delivered to Indemnitee, or (D) if so directed by the Board, by the stockholders of the Company holding a majority of the securities of the Company
entitled to vote; and, if it is so determined that Indemnitee is entitled to indemnification, payment to Indemnitee shall be made within ten (10) days after such determination. Indemnitee shall cooperate with the person, persons or entity
making such determination with respect to Indemnitee’s entitlement to indemnification, including providing to such person, persons or entity upon reasonable advance request any documentation or information which is not privileged or otherwise
protected from disclosure and which is reasonably available to Indemnitee and reasonably necessary to such determination. Any Expenses incurred by Indemnitee in so cooperating with the person, persons or entity making such determination shall, to
the fullest extent permitted by law, 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. The Company
will not deny any written request for indemnification hereunder made in good faith by Indemnitee unless a determination as to Indemnitee’s entitlement to such indemnification described in this Section 10(a) has been
made. 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 Liabilities and Expenses arising out of or relating to this Agreement or its
engagement pursuant hereto. 

  
 7 







 (b)        In the event the
determination of entitlement to indemnification is to be made by Independent Counsel pursuant to Section 10(a) hereof, (i) the Independent Counsel shall be selected by the Company within ten (10) days of the
Submission Date (the cost of such Independent Counsel to be paid by the Company), (ii) the Company shall give written notice to Indemnitee advising it of the identity of the Independent Counsel so selected and (iii) Indemnitee may, within
ten (10) days after such written notice of selection shall have been given, deliver to the Company Indemnitee’s written objection to such selection. Such objection by Indemnitee may be asserted only on the ground that the Independent
Counsel selected does not meet the requirements of “Independent Counsel” as defined in this Agreement. If such written objection is made and substantiated, the Independent Counsel selected shall not serve as Independent Counsel unless and
until Indemnitee withdraws the objection or a court has determined that such objection is without merit. Absent a timely objection, the person so selected shall act as Independent Counsel. If no Independent Counsel shall have been selected and not
objected to before the later of (A) thirty (30) days after the Submission Date and (B) ten (10) days after the final disposition of the Proceeding, including any appeal therein, each of the Company and Indemnitee shall select a
law firm or member of a law firm meeting the qualifications to serve as Independent Counsel, and such law firms or members of law firms shall select the Independent Counsel. 

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)        In making a determination with respect to entitlement to
indemnification hereunder, the person, persons or entity making such determination shall, to the fullest extent not prohibited by applicable law, presume 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, to the fullest extent not prohibited by applicable law, have the burden of proof to overcome that presumption in
connection with the making by any person, persons or entity of any determination contrary to that presumption. Neither the failure of the Company (including by its directors or Independent Counsel) to have made a determination prior to the
commencement of any action pursuant to this Agreement that indemnification is proper in the circumstances because Indemnitee has met the applicable standard of conduct, nor an actual determination by the Company (including by its directors or
Independent 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)        Subject to Section 12(e) hereof, if the person,
persons or entity empowered or selected under Section 10 of this Agreement to determine whether Indemnitee is entitled to indemnification shall not have made a determination within sixty (60) days after receipt by the
Company of the request therefore, the requisite determination of entitlement to indemnification shall, to the fullest extent not prohibited by applicable law, be deemed to have been made and Indemnitee shall be entitled to such indemnification,
absent a prohibition of such 

  
 8 







 
indemnification under applicable law; provided, however, that such 60-day period may be extended for a reasonable time, not to exceed an additional thirty (30) days, if (i) the
determination is to be made by Independent Counsel and Indemnitee objects to the Company’s selection of Independent Counsel and (ii) the Independent Counsel ultimately selected requires such additional time for the obtaining or evaluating
of documentation or information relating thereto; provided further, however, that such 60-day period may also be extended for a reasonable time, not to exceed an additional sixty (60) days, if the determination of entitlement to indemnification
is to be made by the stockholders of the Company. 
 (c)        The termination of
any Proceeding or of any claim, issue or matter therein, by judgment, order, settlement or conviction, or upon a plea of nolo contendere or its equivalent, shall not (except as otherwise expressly provided in this Agreement) 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 Indemnitee 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 Indemnitee’s conduct was unlawful. 

(d)        Reliance as Safe Harbor. For purposes of any determination
of good faith, Indemnitee shall be deemed to have acted in good faith if Indemnitee’s action is based on the records or books of account of the Enterprise, including financial statements, or on information supplied to Indemnitee by the officers
of the Enterprise in the course of their duties, or on the advice of legal counsel for the Enterprise or on information or records given or reports made to the Enterprise by an independent certified public accountant or by an appraiser or other
expert selected with the reasonable care by the Enterprise. The provisions of this Section 11(d) shall not be deemed to be exclusive or to limit in any way the other circumstances in which Indemnitee may be deemed to have
met the applicable standard of conduct set forth in this Agreement. 

(e)        Actions of Others. The knowledge or actions, or failure to
act, of any director, officer, agent or employee of the Enterprise shall not be imputed to Indemnitee for purposes of determining the right to indemnification under this Agreement. 

Section 12.        Remedies of Indemnitee. 

(a)        Subject to Section 12(e) hereof, 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 is not timely made pursuant to
Section 8 of this Agreement, (iii) no determination of entitlement to indemnification shall have been timely made pursuant to Section 10(a) of this Agreement within sixty (60) days after
receipt by the Company of the request for indemnification, (iv) payment of indemnification is not made pursuant to Sections 4 or 5 or the third to the last sentence of Section 10(a) of this Agreement within ten
(10) days after receipt by the Company of a written request therefor, (v) payment of indemnification pursuant to Sections 2, 3 or 6 of this Agreement is not made within ten (10) days after a
determination has been made that Indemnitee is entitled to indemnification, or (vi) 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 

  
 9 







 
provided to Indemnitee hereunder, Indemnitee shall be entitled to an adjudication by a court of Indemnitee’s entitlement to such indemnification or advancement. Alternatively, Indemnitee, at
Indemnitee’s option, may seek an award in arbitration to be conducted by a single arbitrator pursuant to the Commercial Arbitration Rules of the American Arbitration Association. 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 a prohibition of such indemnification under applicable law. 

(d)        The Company shall, to the fullest extent not prohibited by applicable law,
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. It is the intent of the Company that Indemnitee not be required to incur Expenses associated with the interpretation, enforcement or
defense of Indemnitee’s rights under this Agreement by litigation or otherwise because the cost and expense thereof would substantially detract from the benefits intended to be extended to Indemnitee hereunder. The Company shall indemnify
Indemnitee against any and all Expenses and, if requested by Indemnitee, shall (within ten (10) days after receipt by the Company of a written request therefore) advance, to the extent not prohibited by applicable law, such 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 the Bylaws, or under any directors’ and officers’ liability
insurance policies maintained by the Company, regardless of whether Indemnitee ultimately is determined to be entitled to such indemnification, advancement or insurance recovery, as the case may be. 

(e)        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; provided that, in absence of any such determination with respect to
such Proceeding, the Company shall advance Expenses with respect to such Proceeding. 

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 

  
 10 







 
any time be entitled under applicable law, the Certificate of Incorporation, 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 Indemnitee’s Corporate Status prior to such amendment,
alteration or repeal. The Company shall not adopt any amendment or alteration to, or repeal of, the Certificate of Incorporation or the Bylaws, the effect of which would be to deny, diminish or encumber the Indemnitee’s rights to
indemnification pursuant to this Agreement, the Certificate of Incorporation, the Bylaws or applicable law relative to such rights 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 Bylaws or 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)        The Company hereby acknowledges that Indemnitee may have certain rights to
indemnification, advancement and insurance provided by one or more Persons with whom or which Indemnitee may be associated (including, without limitation, any Sponsor Entity). The Company hereby acknowledges and agrees that
(i) the Company shall be the indemnitor of first resort with respect to any Proceeding, Expense, Liability or matter that is the subject of the Indemnity Obligations, (ii) the Company
shall be primarily liable for all Indemnity Obligations and any indemnification afforded to Indemnitee in respect of any Proceeding, Expense, Liability or matter that is the subject of Indemnity Obligations, whether created by
applicable law, organizational or constituent documents, contract (including this Agreement) or otherwise, (iii) any obligation of any other Persons with whom or which Indemnitee may be associated (including, without
limitation, any Sponsor Entity) to indemnify Indemnitee or advance Expenses or Liabilities to Indemnitee in respect of any Proceeding shall be secondary to the obligations of the Company hereunder,
(iv) the Company shall be required to indemnify Indemnitee and advance Expenses or Liabilities to Indemnitee hereunder to the fullest extent provided herein without regard to any rights
Indemnitee may have against any other Person with whom or which Indemnitee may be associated (including, without limitation, any Sponsor Entity) or insurer of any such Person and (v) the Company
irrevocably waives, relinquishes and releases any other Person with whom or which Indemnitee may be associated (including, without limitation, any Sponsor Entity) from any claim of contribution, subrogation or any other recovery of any
kind in respect of amounts paid by the Company hereunder. In the event any other Person with whom or which Indemnitee may be associated (including, without limitation, any Sponsor Entity) or their insurers advances or extinguishes any liability
or loss which is the subject of any Indemnity Obligation owed by the Company or payable under any Company insurance policy, the payor shall have a right of subrogation against the Company or its insurer or insurers for all amounts so paid which
would otherwise be payable by the Company or its insurer or insurers under this Agreement. In no event will payment of an Indemnity Obligation by any other Person with whom or which Indemnitee may be associated (including, without limitation, any
Sponsor Entity) or their insurers affect the obligations of the Company hereunder 

  
 11 







 
or shift primary liability for any Indemnity Obligation to any other Person with whom or which Indemnitee may be associated (including, without limitation, any Sponsor Entity). Any
indemnification, insurance or advancement provided by any other Person with whom or which Indemnitee may be associated (including, without limitation, any Sponsor Entity) with respect to any liability arising as a result of Indemnitee’s
Corporate Status or capacity as an officer or director of any Person is specifically in excess over any Indemnity Obligation of the Company or valid and any collectible insurance (including but not limited to any malpractice insurance or
professional errors and omissions insurance) provided by the Company under this Agreement. 

(c)        To the extent that the Company maintains an insurance policy or policies
providing liability insurance for directors, officers, employees, trustees, or agents of any 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, officer, employee, trustee or agent under such policy or policies and such policies shall provide for and recognize that the insurance policies are primary to any rights to indemnification, advancement or insurance proceeds to
which Indemnitee may be entitled from one or more Persons with whom or which Indemnitee may be associated (including, without limitation, any Sponsor Entity) to the same extent as the Company’s indemnification and advancement obligations set
forth in this Agreement. 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. 

(d)        In the event of any payment under this Agreement, the Company shall be
subrogated to the rights of recovery of Indemnitee, including rights of indemnification provided to Indemnitee from any other person or entity with whom Indemnitee may be associated; provided, however, that the Company shall not be subrogated to the
extent of any such payment of all rights of recovery of Indemnitee with respect to any Person with whom or which Indemnitee may be associated (including, without limitation, any Sponsor Entity). 

(e)        The indemnification and contribution provided for in this Agreement will
remain in full force and effect regardless of any investigation made by or on behalf of Indemnitee. 

Section 14.        Duration of Agreement; Not Employment Contract.
This Agreement shall be binding upon the Company and its successors and assigns and shall inure to the benefit of Indemnitee and Indemnitee’s heirs, executors and administrators. The Company shall require and cause any successor, and any direct
or indirect parent of 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. This Agreement shall not be
deemed an employment contract between the Company (or any of its subsidiaries or any other Enterprise) and Indemnitee. Indemnitee specifically acknowledges that Indemnitee’s employment with the Company (or any


  
 12 







 
of its subsidiaries or any other Enterprise), if any, is at will, and Indemnitee may be discharged at any time for any reason, with or without cause, except as may be otherwise provided in any
written employment contract between Indemnitee and the Company (or any of its subsidiaries or any other Enterprise), other applicable formal severance policies duly adopted by the Board, or, with respect to service as a director of the Company, by
the Certificate of Incorporation, the Bylaws or the DGCL. 

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 applicable 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 as a director, officer, employee or agent of the Company, and the Company acknowledges that Indemnitee is relying upon this Agreement in serving as a
director, officer, employee or agent 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 Certificate of Incorporation, the Bylaws and applicable law, and shall not be deemed a substitute therefore, nor diminish or abrogate any rights of
Indemnitee thereunder. 
 Section 17.        Modification and
Waiver. No supplement, modification or amendment of this Agreement shall be binding unless executed in writing by the parties thereto. No waiver of any of the provisions of this Agreement shall be deemed to be or shall constitute a waiver of
any other provision of this Agreement nor shall any waiver constitute a continuing waiver. 

Section 18.        Notices. All notices, requests, demands and
other communications under this Agreement shall be in writing and shall be deemed to have been duly given if (a) delivered by hand and receipted for by the party to whom said notice or other communication shall have been directed,
(b) mailed by certified or registered mail with postage prepaid, on the third business day after the date on which it is so mailed, (c) mailed by reputable overnight courier and receipted for by the party to whom said notice or other
communication shall have been directed

Section 19.        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
Liabilities or for Expenses, in connection with any Proceeding, in such proportion as is deemed fair and reasonable in light of all of the circumstances of such Proceeding in order to reflect (a) the relative benefits received by the Company
and Indemnitee as a result of the event(s) and transaction(s) giving cause to such Proceeding; and (b) the relative fault of the Company (and its directors, officers, employees and agents) and Indemnitee in connection with such event(s) and
transaction(s). 
 Section 20.        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. Except with respect
to any arbitration commenced by Indemnitee pursuant to Section 12(a) of this Agreement, the Company and Indemnitee hereby irrevocably and unconditionally (a) agree that any action or proceeding arising out of or in
connection with this Agreement shall be brought only in the Chancery Court of the State of Delaware (the “Delaware Court”), and not in any other state or federal court in the United States of America or any court in any other
country, (b) 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, (c) consent to service of process at the address set forth in
Section 18 of this Agreement with the same legal force and validity as if served upon such party personally within the State of Delaware; (d) waive any objection to the laying of venue of any such action or proceeding
in the Delaware Court, and (e) 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. 

Section 21.        Counterparts. This Agreement may be executed in
one or more counterparts, each of which shall for all purposes be deemed to be an original but all of which together shall constitute one and the same Agreement. Only one such counterpart signed by the party against whom enforceability is sought
needs to be produced to evidence the existence of this Agreement.

Section 23.        Miscellaneous. Use of the masculine pronoun
shall be deemed to include usage of the feminine pronoun where appropriate. The headings of the paragraphs of this Agreement are inserted for convenience only and shall not be deemed to constitute part of this Agreement or to affect the construction
