6



---

connection with its purchase and/or ownership of equity interests in the Company Group or its involvement in the Transactions, from and against any and all

3. Contribution.

(a) If for any reason the indemnity provided for in Section 2(a) is unavailable or is insufficient to hold harmless any Indemnitee from any of the Obligations covered by such indemnity, then the Indemnifying
Parties, jointly and severally, shall contribute to the amount paid or payable by such Indemnitee as a result of such Obligation in such proportion as is appropriate to reflect (i) the relative fault of each member of the Company Group, on the
one hand, and such Indemnitee, on the other, in connection with the state of facts giving rise to such Obligation, (ii) if such Obligation results from, arises out of, is based upon or relates to the Transactions or any Securities Offering, the
relative benefits received by each member of the Company Group, on the one hand, and such Indemnitee, on the other, from such Transaction or Securities Offering and (iii) if required by applicable law, any other relevant equitable
considerations.

(b) If for any reason the indemnity specifically provided for in Section 2(b) is unavailable or is insufficient to
hold harmless any Indemnitee from any of the Obligations covered by such indemnity, then the Indemnifying Parties, jointly and severally, shall contribute to the amount paid or payable by such Indemnitee as a result of such Obligation in such
proportion as is appropriate to reflect (i) the relative fault of each of the members of the Company Group, on the one hand, and such Indemnitee, on the other, in connection with the information contained in or omitted from any Related
Document, which inclusion or omission resulted in the inaccuracy or breach of or default under any representation, warranty, covenant or agreement therein, or which information is or is alleged to be untrue, required to be stated therein or
necessary to make the statements therein not misleading, (ii) the relative benefits received by the members of the Company Group, on the one hand, and such Indemnitee, on the other, from such Transaction or Securities Offering and (iii) if
required by applicable law, any other relevant equitable considerations.

(c) For purposes of Section 3(a), the relative fault of each
member of the Company Group, on the one hand, and of an Indemnitee, on the other, shall be determined by reference to, among other things, their respective relative intent, knowledge, access to information and opportunity to correct the state of
facts giving rise to such Obligation. For purposes of Section 3(b), the relative fault of each of the members of the Company Group, on the one hand, and of an Indemnitee, on the other, shall be determined by reference to, among other things,
(i) whether the included or omitted information relates to information supplied by the members of the Company Group, on the one hand, or by such Indemnitee, on the other, (ii) their respective relative intent, knowledge, access to
information and opportunity to correct such inaccuracy, breach, default, untrue or alleged untrue statement, or omission or alleged omission, and (iii) applicable law. For purposes of Section 3(a) or 3(b), the relative benefits received by
each member of the Company Group, on the one hand, and an Indemnitee, on the other, shall be determined by weighing the direct monetary proceeds to the Company Group, on the one hand, and such Indemnitee, on the other, from such Transaction or
Securities Offering.

---

(d) The parties hereto acknowledge and agree that it would not be just and equitable if contributions
pursuant to Section 3(a) or 3(b) were determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to in such respective Section. No Indemnifying Party shall be
liable under Section 3(a) or 3(b), as applicable, for contribution to the amount paid or payable by any Indemnitee except to the extent and under such circumstances such Indemnifying Party would have been liable to indemnify, defend and hold
harmless such Indemnitee under the corresponding Section 2(a) or 2(b), as applicable, if such indemnity were enforceable under applicable law. No Indemnitee shall be entitled to contribution from any Indemnifying Party with respect to any
Obligation covered by the indemnity specifically provided for in Section 2(b) in the event that such Indemnitee is finally determined to be guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act)
in connection with such Obligation and the Indemnifying Parties are not guilty of such fraudulent misrepresentation.

4. Indemnification
Procedures.

(a) Whenever any Indemnitee shall have actual knowledge of the assertion of a Claim against it, such Indemnitee shall
notify the appropriate member of the Company Group in writing of the Claim (the Notice of Claim) with reasonable promptness after such Indemnitee has such knowledge relating to such Claim; provided the failure or delay of
such Indemnitee to give such Notice of Claim shall not relieve any Indemnifying Party of its indemnification obligations under this Agreement except to the extent that such omission results in a failure of actual notice to it and it is materially
injured as a result of the failure to give such Notice of Claim. The Notice of Claim shall specify all material facts known to such Indemnitee relating to such Claim and the monetary amount or an estimate of the monetary amount of the Obligation
involved if such Indemnitee has knowledge of such amount or a reasonable basis for making such an estimate. The Indemnifying Parties shall, at their expense, undertake the defense of such Claim with attorneys of their own choosing reasonably
satisfactory in all respects to such Indemnitee, subject to the right of such Indemnitee to undertake such defense as hereinafter provided. An Indemnitee may participate in such defense with counsel of such Indemnitees choosing at the expense
of the Indemnifying Parties. In the event that the Indemnifying Parties do not undertake the defense of the Claim within a reasonable time after such Indemnitee has given the Notice of Claim, or in the event that such Indemnitee shall in good faith
determine that the defense of any claim by the Indemnifying Parties is inadequate or may conflict with the interest of any Indemnitee (including without limitation, Claims brought by or on behalf of any member of the Company Group), such Indemnitee
may, at the expense of the Indemnifying Parties and after giving notice to the Indemnifying Parties of such action, undertake the defense of the Claim and compromise



9



---

or settle the Claim, all for the account of and at the risk of the Indemnifying Parties. In the defense of any Claim against an Indemnitee, no Indemnifying
Party shall, except with the prior written consent of such Indemnitee, consent to entry of any judgment or enter into any settlement that includes any injunctive or other non-monetary relief or any payment of money by such Indemnitee, or that does
not include as an unconditional term thereof the giving by the Person or Persons asserting such Claim to such Indemnitee of an unconditional release from all liability on any of the matters that are the subject of such Claim and an acknowledgement
that such Indemnitee denies all wrongdoing in connection with such matters. The Indemnifying Parties shall not be obligated to indemnify an Indemnitee against amounts paid in settlement of a Claim if such settlement is effected by such Indemnitee
without the prior written consent of the Company (on behalf of all Indemnifying Parties), which shall not be unreasonably withheld. In each case, each Indemnitee seeking indemnification hereunder will cooperate with the Indemnifying Parties, so long
as an Indemnifying Party is conducting the defense of the Claim, in the preparation for and the prosecution of the defense of such Claim, including making available evidence within the control of such Indemnitee, as the case may be, and persons
needed as witnesses who are employed by such Indemnitee, as the case may be, in each case as reasonably needed for such defense and at cost, which cost, to the extent reasonably incurred, shall be paid by the Indemnifying Parties.

(b) An Indemnitee shall notify the Indemnifying Parties in writing of the amount requested for advances (Notice of Advances). The
Indemnifying Parties hereby agree to advance reasonable costs and Expenses incurred by any Indemnitee in connection with any Claim (but not for any Claim initiated or brought voluntarily by an Indemnitee other than a Proceeding pursuant to
Section 2(c)) in advance of the final disposition of such Claim without regard to whether such Indemnitee will ultimately be entitled to be indemnified for such costs and expenses upon receipt of an undertaking by or on behalf of such
Indemnitee to repay amounts so advanced if it shall ultimately be determined in a decision of a court of competent jurisdiction from which no appeal can be taken that such Indemnitee is not entitled to be indemnified by the Indemnifying Parties as
authorized by this Agreement. The Indemnifying Parties shall make payment of such advances no later than 10 days after the receipt of the Notice of Advances.

(c) An Indemnitee shall notify the Indemnifying Parties in writing of the amount of any Claim actually paid by such Indemnitee (the Notice of Payment). The amount of any Claim actually paid by such
Indemnitee shall bear simple interest at the rate equal to the JPMorgan Chase Bank, N.A. prime rate as of the date of such payment plus 2% per annum, from the date the Indemnifying Parties receive the Notice of Payment to the date on which any
Indemnifying Party shall repay the amount of such Claim plus interest thereon to such Indemnitee. The Indemnifying Parties shall make indemnification payments to such Indemnitee no later than 30 days after receipt of the Notice of Payment.



10



---

(d) Independent Legal Counsel. If there has not been a Change in Control, independent legal
counsel shall be selected by the board of directors of the Company and approved by such Indemnitee (which approval shall not be unreasonably withheld or delayed). If there has been a Change in Control, independent legal counsel shall be
selected by such Indemnitee and approved by the Company (which approval shall not be unreasonably withheld or delayed). The Indemnifying Parties shall pay the fees and expenses of independent legal counsel and indemnify independent legal counsel
against any and all Expenses, claims, liabilities and damages arising out of or relating to its engagement.

5. Certain Covenants.
The rights of each Indemnitee to be indemnified under any other agreement, document, certificate or instrument or applicable law are independent of and in addition to any rights of such Indemnitee to be indemnified under this Agreement. The rights
of each Indemnitee and the obligations of the Indemnifying Parties hereunder shall remain in full force and effect regardless of any investigation made by or on behalf of such Indemnitee. Following the Transactions, each of the Company Entities, and
each of their corporate successors, shall implement and maintain in full force and effect any and all corporate charter and by-law (or similar organizational document) provisions that may be necessary or appropriate to enable it to carry out its
obligations hereunder to the fullest extent permitted by applicable law, including without limitation a provision of its certificate of incorporation (or similar organizational document) eliminating liability of a director for breach of fiduciary
duty to the fullest extent permitted by applicable law, as amended from time to time. So long as the Company or any other member of the Company Group maintains liability insurance for any directors, officers, employees or agents of any such Person,
the Indemnifying Parties shall ensure that each Indemnitee serving in such capacity is covered by such insurance in such a manner as to provide such Indemnitee the same rights and benefits as are accorded to the most favorably insured of the
Companys and the Company Groups then current directors and officers.

6. Notices. All notices and other communications
hereunder shall be in writing and shall be delivered by certified or registered mail (first class postage prepaid and return receipt requested), telecopier, overnight courier or hand delivery, as follows:

or to such other address or such other person as the Company Entities or the applicable Manager shall have
designated by notice to the other parties hereto. All communications hereunder shall be effective upon receipt by the party to which they are addressed.

8. Governing Law; Jurisdiction, Waiver of Jury Trial. This Agreement shall be governed in all respects, including validity, interpretation and effect, by the law of the State of New York, regardless of the law
that might be applied under principles of conflict of laws to the extent such principles would require or permit the application of the laws of another jurisdiction. Each of the parties hereto irrevocably and unconditionally (a) agrees that any
legal suit, action or proceeding brought by any party

---

hereto arising out of or based upon this Agreement or the transactions contemplated hereby may be brought in any court of the State of New York or Federal
District Court for the Southern District of New York located in the City, County and State of New York (each, a New York Court), (b) waives, to the fullest extent that it may effectively do so, any objection that it may now
or hereafter have to the laying of venue of any such proceeding brought in a New York Court, and any claim that any such action or proceeding brought in a New York Court has been brought in an inconvenient forum, (c) submits to the
non-exclusive jurisdiction of any New York Court in any suit, action or proceeding and (d) ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY THAT MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE
HEREBY WAIVES ANY RIGHT THAT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, OR THE BREACH, TERMINATION OR VALIDITY OF THIS AGREEMENT. With respect to clause
(d) of the immediately preceding sentence, each of the parties hereto acknowledges and certifies that (i) no representative, agent or attorney of any other party has represented, expressly or otherwise, that such other party would not, in
the event of litigation, seek to enforce the waiver contained therein, (ii) it understands and has considered the implications of such waiver, (iii) it makes such waiver voluntarily and (iv) it has been induced to enter into this
Agreement by, among other things, the mutual waivers and certifications contained in this Section 7.

9. Severability. If any
provision or provisions of this Agreement shall be held to be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions hereof shall not in any way be affected or impaired thereby.

10. Successors; Binding Effect. Each Indemnifying Party will require any successor (whether direct or indirect, by purchase, merger,
consolidation, reorganization or otherwise) to all or substantially all of the business and assets of such Indemnifying Party, by agreement in form and substance satisfactory to the Managers and their counsel, expressly to assume and agree to
perform this Agreement in the same manner and to the same extent that such Indemnifying Party would be required to perform if no such succession had taken place. This Agreement shall be binding upon and inure to the benefit of each party hereto and
its successors and permitted assigns, and each other Indemnitee, but neither this Agreement nor any right, interest or obligation hereunder shall be assigned, whether by operation of law or otherwise, by the Company without the prior written consent
of the Managers.

11. Miscellaneous. The headings contained in this Agreement are for reference purposes only and shall not affect
in any way the meaning or interpretation of this Agreement. This Agreement is not intended to confer any right or remedy hereunder upon any Person other than each of the parties hereto and their respective successors and



14

permitted assigns and each other Indemnitee. No amendment, modification, supplement or discharge of this Agreement, and no waiver hereunder shall be valid
and binding unless set forth in writing and duly executed by the party or other Indemnitee against whom enforcement of the amendment, modification, supplement or discharge is sought. Neither the waiver by any of the parties hereto or any other
Indemnitee of a breach of or a default under any of the provisions of this Agreement, nor the failure by any party hereto or any other Indemnitee on one or more occasions, to enforce any of the provisions of this Agreement or to exercise any right,
powers or privilege hereunder, shall be construed as a waiver of any other breach or default of a similar nature, or as a waiver of any provisions hereof, or any rights, powers or privileges hereunder. The rights, indemnities and remedies herein
provided are cumulative and are not exclusive of any rights, indemnities or remedies that any party or other Indemnitee may otherwise have by contract, at law or in equity or otherwise. This Agreement may be executed in several counterparts, each of
which shall be deemed an original, and all of which together shall constitute one and the same instrument.
