Except as otherwise specified herein, all capitalized terms shall have the meaning given in the Memorandum and Articles of Association
of the Company (the “Articles”). 
 1. Voting Provisions Regarding Board of Directors. 

1.1 Board Composition. Each Member agrees to take any action including without limitation, to vote, or cause to be voted, all Shares

take any action, including without limitation, to vote, or cause to be voted, all Shares owned by such Member, or over which such Member has voting control, from time to time and at all times, in whatever manner as shall be necessary, to ensure that
a director shall only be removed by, and shall be removed at the proposal of, FP. 
 1.3 Written Consent. All Members agree to

for any such designee in accordance with the provisions of this Agreement. 

 2. Other Voting Agreements. Each Member agrees to take any action, including without
limitation, to vote or cause to be voted all Shares owned by such Member, or over which such Member has voting control, from time to time and at all times, in whatever manner as shall be necessary, to (x) increase the number of authorized
shares of Common Stock from time to time to ensure that there will be sufficient shares of Common Stock available for conversion of all of the shares of the Company’s Series A Preferred Stock outstanding at any given time, and (y) fulfill
the obligations of such Member under Section 10.2 of the Articles. 
 3. Representations and Warranties; Agreements. 

3.1 Each Member represents and warrants as of the date hereof that (a) this Agreement has been duly authorized, executed and delivered by
such Member and constitutes the valid and binding obligation of such Member, enforceable in accordance with its terms, and (b) such Member has not granted, and is not a party to, any proxy, voting trust or other agreement which is inconsistent
with, conflicts with or violates any provision of this Agreement. 
 3.2 No holder of Member Shares shall grant any proxy or become party to
any voting trust or other agreement which is inconsistent with, conflicts with or violates any provision of this Agreement. 
 3.2 Each
Member expressly acknowledges and agrees to be bound by the restrictions on transfer of Shares set forth in Section 7 of the Articles. In furtherance thereof, each Member agrees (i) not to engage in any Transfer of Shares other than in
accordance with Section 7 of the Articles, (ii) with respect to any Transfer permitted by Section 7 of the Articles to any Person who is not a Member, obtain an Adoption Agreement from such Person in the form of Exhibit A
attached hereto (whereupon such Person shall be deemed to be a Member and a party to this Agreement as if such Person were the transferor and such transferee’s signature appeared on the signature page of the Members Agreement and shall be
deemed to be an Investor or a Key Holder, as appropriate) 
 3.3 The Investors hereby agree that they will not engage, or permit the Company
to engage, in a Sale of the Company without invoking the provisions of Section 10.2 of the Articles. 
 4. Preemptive Rights.

 4.1 Except for issuance of Common Stock upon the conversion of the Preferred Stock, upon the sale of any equity securities or any
securities (including debt securities) containing options or rights to acquire any shares of Common Stock (other than as a dividend on the outstanding shares of Common Stock) or any securities exchangeable for or convertible into Common Stock
(collectively, “Securities”) to any Investor, the Company shall also offer to sell to each Key Member a portion of the Securities offered in such issuance equal to the quotient determined by dividing (A) the number of shares of
Common Stock held by such Key Member (including shares of Common Stock issuable upon conversion of the Preferred Stock) by (B) the total number of shares of Common Stock then outstanding (including shares of Common Stock issuable upon
conversion of the Preferred Stock). Each of the Key Members shall be entitled to purchase all or any portion of its allotment of such Securities at the most 

  
 2 

 
favorable price and on the most favorable terms as such Securities are to be offered to the Investors; provided that if the Investors are required to also purchase other securities
of the Company, the Persons exercising their rights pursuant to this Section 4 shall also be required to purchase the same strip of securities (on the same terms and conditions) that the Investors are required to purchase. The purchase price
for all Securities offered to the Members shall be payable in cash or, to the extent otherwise consistent with the terms offered to the Investors, installments over time. 

4.2 In order to exercise its purchase rights hereunder, a Member must within 20 days after receipt of written notice from the Company
describing in reasonable detail the Securities being offered, the purchase price thereof, the payment terms and such Member’s percentage allotment deliver a written notice to the Company describing its election hereunder. If all of the
Securities offered to the Member are not fully subscribed by such Members, the remaining Securities shall be reoffered by the Company to the Members, as applicable, purchasing their full allotment upon the terms set forth in this Section 4,
except that such holders must exercise their purchase rights within five (5) days after receipt of such reoffer. 
 4.3 Upon the
expiration of the offering periods described above, the Company shall be entitled to sell such Securities which the Members have not elected to purchase during the 60 days following such expiration on terms and conditions no more favorable to the
purchasers thereof than those offered to such holders. Any Securities offered or sold by the Company after such 60-day period must be reoffered to the Members pursuant to the terms of this Section 4. 

4.4 Notwithstanding anything to the contrary herein, this Section 4 shall not apply to the issuance of Exempted Securities. 

5. Investor Approval Rights. In addition to the actions requiring Investor approval set forth in Section 53.2 of the Articles (all
of which are incorporated herein by reference), each Member hereby agrees that it will take all such actions, and refrain from taking all such actions, as is necessary to ensure that the Company and each of its subsidiaries does not do any of the
following without prior approval from the Investors: 
 (a) liquidate the business and affairs of the Company or any of its
subsidiaries, including, for the avoidance of doubt, commencement of voluntary liquidation proceedings; or 
 (b) amend any
provision of the constitutional documents of the Company or any of its subsidiaries. 
 6. Remedies. 

6.1 Covenants of the Company. The Company agrees to use its best efforts, within the requirements of applicable law, to ensure that the
rights granted under this Agreement are effective and that the parties enjoy the benefits of this Agreement. Such actions include, without limitation, the use of the Company’s best efforts to cause the nomination and election of the directors
as provided in this Agreement. 

  
 3 

 6.2 Irrevocable Proxy and Power of Attorney. Each party to this Agreement other than the
Investors hereby constitutes and appoints the Directors of the Company, and each of them, with full power of substitution, as the proxies of the party with respect to the matters set forth herein, and hereby authorizes each of them to represent and
to vote, if and only if the party fails to vote all of such party’s Shares as required in accordance with the terms and provisions of Sections 1, and 2, respectively, of this Agreement. The proxy granted pursuant to the
immediately preceding sentence is given in consideration of the agreements and covenants of the Company and the parties in connection with the transactions contemplated by this Agreement and, as such, is coupled with an interest and shall be
irrevocable unless and until this Agreement terminates or expires pursuant to Section 7 hereof. Each party hereto hereby revokes any and all previous proxies with respect to the Shares and shall not hereafter, unless and until this
Agreement terminates or expires pursuant to Section 7 hereof, purport to grant any other proxy or power of attorney with respect to any of the Shares, deposit any of the Shares into a voting trust or enter into any agreement (other than
this Agreement), arrangement or understanding with any person, directly or indirectly, to vote, grant any proxy or give instructions with respect to the voting of any of the Shares, in each case, with respect to any of the matters set forth herein.

 6.3 Specific Enforcement. Each party acknowledges and agrees that each party hereto will be irreparably damaged in the event any
of the provisions of this Agreement are not performed by the parties in accordance with their specific terms or are otherwise breached. Accordingly, it is agreed that each of the Company and the Members shall be entitled to an injunction to prevent
breaches of this Agreement, and to specific enforcement of this Agreement and its terms and provisions in any action instituted in any court of the United States or any state having subject matter jurisdiction. 

6.4 Remedies Cumulative. All remedies, either under this Agreement or by law or otherwise afforded to any party, shall be cumulative
and not alternative. 
 7. Term. This Agreement shall be effective as of the date hereof and shall continue in effect until and shall
terminate upon the earlier to occur of (a) the consummation of a Sale of the Company and distribution of proceeds to or escrow for the benefit of the Members in accordance with the Articles; and (b) termination of this Agreement in
accordance with Section 8.6 below.

under or by reason of this Agreement, except as expressly provided in this Agreement. 
 8.2 Governing Law. This Agreement and any
controversy arising out of or relating to this Agreement shall be governed by and construed in accordance with the General Corporation Law of the State of Delaware without regard to conflict of law principles that would result in the application of

Section 8.5. If notice is given to the Company, or to the Investors, a copy (which shall not constitute notice) shall also be given to Kirkland & Ellis LLP, 950 Page Mill Road, Palo Alto, CA 94304, Attn: Adam D. Phillips. 

8.6 Consent Required to Amend, Terminate or Waive. This Agreement may be amended or terminated and the observance of any term hereof

issuable upon conversion of the shares of Series A Preferred Stock held by the Investors (voting as a single class and on an as-converted basis); and (c) in the case of an amendment or waiver which would adversely affect the rights of the Key
Holders in a manner disproportionate to any adverse effect such amendment or waiver would have on the rights of the Investors, the written consent of the holders of at least a majority of the shares of capital stock held by the Key Holders (voting
as a single class), it being the understanding of and agreement among the parties that upon the consummation of the Company’s first underwritten public offering of its Common Stock (other than a registration statement relating either to the
sale of securities to employees of the Company pursuant to its stock option, stock purchase or similar plan or an SEC Rule 145 transaction) (the “IPO”), this Agreement will be amended to provide for (w) Board representation for

Directors to the Board and support their election by the Company’s shareholders, (y) the incorporation of the approval rights set forth in Section 53.2 of the Articles that FP desires to have post-IPO and (z) pre-emptive rights

 5 

 The Company shall give prompt written notice of any amendment, termination or waiver here-under to any party that
did not consent in writing thereto. Any amendment, termination or waiver effected in accordance with this Section 8.6 shall be binding on each party and all of such party’s successors and permitted assigns, whether or not any such
party, successor or assignee entered into or approved such amendment, termination or waiver. 
 8.7 Delays or Omissions. No delay or
omission to exercise any right, power or remedy accruing to any party under this Agreement, upon any breach or default of any other party under this Agreement, shall impair any such right, power or remedy of such non-breaching or non-defaulting
party nor shall it be construed to be a waiver of any such breach or default, or an acquiescence therein, or of or in any similar breach or default thereafter occurring; nor shall any waiver of any single breach or default be deemed a waiver of any
other breach or default previously or thereafter occurring. Any waiver, permit, consent or approval of any kind or character on the part of any party of any breach or default under this Agreement, or any waiver on the part of any party of any
provisions or conditions of this Agreement, must be in writing and shall be effective only to the extent specifically set forth in such writing. All remedies, either under this Agreement or by law or otherwise afforded to any party, shall be
cumulative and not alternative. 
 8.8 Severability. The invalidity or unenforceability of any provision hereof shall in no way
affect the validity or enforceability of any other provision. 
 8.9 Entire Agreement. This Agreement (including the Schedules and
Exhibits hereto), the Articles and the other Transaction Agreements constitute the full and entire understanding and agreement between the parties with respect to the subject matter hereof, and any other written or oral agreement relating to the
subject matter hereof existing between the parties is expressly canceled. 
 8.10 Legend on Share Certificates. Each certificate
representing any Shares issued after the date hereof shall be endorsed by the Company with a legend reading substantially as follows: 

“THE SHARES EVIDENCED HEREBY ARE SUBJECT TO A VOTING AGREEMENT, AS MAY BE AMENDED FROM TIME TO TIME, (A COPY OF WHICH MAY BE OBTAINED UPON
WRITTEN REQUEST FROM THE COMPANY), AND BY ACCEPTING ANY INTEREST IN SUCH SHARES THE PERSON ACCEPTING SUCH INTEREST SHALL BE DEEMED TO AGREE TO AND SHALL BECOME BOUND BY ALL THE PROVISIONS OF THAT VOTING AGREEMENT, INCLUDING CERTAIN RESTRICTIONS ON
TRANSFER AND OWNERSHIP SET FORTH THEREIN.” 
 The Company, by its execution of this Agreement, agrees that it will cause any certificates evidencing
the Shares issued after the date hereof to bear the legend required by this Section 8.10 of this Agreement, and it shall supply, free of charge, a copy of this Agreement to any holder of a

  
 6 

 
certificate evidencing Shares upon written request from such holder to the Company at its principal office. The parties to this Agreement do hereby agree that the failure to cause any
certificates evidencing the Shares to bear the legend required by this Section 8.10 herein and/or the failure of the Company to supply, free of charge, a copy of this Agreement as provided hereunder shall not affect the validity or
enforcement of this Agreement. 
 8.11 Stock Splits, Stock Dividends, etc. In the event of any issuance of Shares of the
Company’s voting securities hereafter to any of the Members (including, without limitation, in connection with any stock split, stock dividend, recapitalization, reorganization, or the like), such Shares shall become subject to this Agreement
and shall be endorsed with the leg-end set forth in Section 8.10. 
 8.12 Manner of Voting. The voting of Shares pursuant

such further action as the other party may reasonably request in order to evidence or effectuate the consummation of the transactions contemplated hereby and to otherwise carry out the intent of the parties hereunder. 

8.14 Dispute Resolution. The parties (a) hereby irrevocably and unconditionally submit to the jurisdiction of the state courts of
Delaware for the purpose of any suit, action or other proceeding arising out of or based upon this Agreement, (b) agree not to commence any suit, action or other proceeding arising out of or based upon this Agreement except in the state courts
of Delaware, and (c) hereby waive, and agree not to assert, by way of motion, as a defense, or otherwise, in any such suit, action or proceeding, any claim that it is not subject personally to the jurisdiction of the above-named courts, that
its property is exempt or immune from attachment or execution, that the suit, action or proceeding is brought in an inconvenient forum, that the venue of the suit, action or proceeding is improper or that this Agreement or the subject matter hereof
may not be enforced in or by such court. 
 WAIVER OF JURY TRIAL: EACH PARTY HEREBY WAIVES ITS RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE
OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT, THE OTHER TRANSACTION DOCUMENTS, THE SECURITIES OR THE SUBJECT MATTER HEREOF OR THEREOF. THE SCOPE OF THIS WAIVER IS INTENDED TO BE ALL-ENCOMPASSING OF ANY AND ALL DISPUTES THAT MAY BE FILED IN

ICICLE ACQUISITION HOLDING, LLC 

MANAGEMENT SERVICES AGREEMENT 

THIS MANAGEMENT SERVICES AGREEMENT (this “Agreement”) is made and entered into as of 30 December, 2011 (the
“Effective Date”) between Icicle Acquisition Holding, LLC, a Delaware limited liability company (the “Company”), and Francisco Partners Management, LLC, a Delaware limited liability company
(“Advisor”). 
 WHEREAS, pursuant to that certain Securities Purchase and Sale Agreement, dated as of December 3, 2011
(as amended or otherwise modified from time to time in accordance with its terms, the “Sale and Purchase Agreement”), by and among the Company, Ichor Systems Holdings, LLC (the “Sellers’ Representative”), Ichor
Systems, Inc. (“Ichor”), and Precision Flow Technologies, Inc. (“PFT”), the Company has agreed to buy all of the equity interests in Ichor and PFT in consideration for payment of the Purchase Price (as defined in the Sale and
Purchase Agreement) to the Sellers’ Representative; 
 WHEREAS, the Company desires to receive financial and management advisory
services from Advisor and to obtain the benefit of Advisor’s experience in business and financial management generally and its knowledge of the Company and the Company’s financial affairs in particular, and Advisor is willing to provide
financial and management advisory services to the Company; and 
 WHEREAS, the compensation arrangements set forth in this Agreement are
designed to compensate Advisor for providing such financial and management advisory services to the Company. 
 NOW, THEREFORE, in
consideration of the foregoing premises, the respective agreements hereinafter set forth and the mutual benefits to be derived therefrom, Advisor and the Company hereby agree as follows: 

1. Engagement. The Company hereby engages Advisor as a general financial and management advisor, and Advisor hereby agrees to provide
certain financial and management advisory services to the Company, all on the terms and subject to the conditions set forth in this Agreement. 

2. Services. Advisor hereby agrees during the term of this engagement to consult with and advise the boards of directors of the Company
and its affiliates and the management of the Company and its affiliates in such manner and on such business and financial matters as may be reasonably requested from time to time and as may be reasonably agreed to by Advisor, including:
(a) general advisory services in relation to the Company’s management and business, (b) identification, analysis, support and negotiation of acquisitions and dispositions, (c) analysis, support and negotiation of financing
alternatives, including in connection with acquisitions, capital expenditures and refinancings of existing indebtedness, (d) finance functions, including assistance in the preparation of financial projections, and (e) strategic planning
functions, including the evaluation of major strategic alternatives. The Company acknowledges that Advisor’s services are not exclusive to the Company and its affiliates and that Advisor will render similar services to other persons and
entities. Notwithstanding anything herein to the contrary, it is understood and agreed that the Company and its affiliates are not precluded hereby from engaging other persons in addition to Advisor to provide investment banking or other advisory
services to the Company and/or its affiliates during the term of this Agreement, including advisory services which may be the same as those also provided by Advisor, and any such engagement of another person shall not affect or impair Advisor’s
right to receive the fees set forth herein. 

 3. Personnel. Advisor shall provide and devote to the performance of this Agreement such
of its partners, members and employees as Advisor shall deem appropriate in its discretion for the furnishing of the services to be provided hereunder; provided, however, that no minimum number of hours is required to be devoted by Advisor or its
partners, members or employees on a weekly, monthly, annual or other basis. 
 4. Annual Management Fee. Commencing on the Effective
Date and subject to Section 6 below, the Company shall pay to Advisor an annual management fee (the “Annual Management Fee”) equal to $1,500,000. The Annual Management Fee shall be payable in advance in immediately
available funds in equal quarterly installments. Quarterly installments shall be made on the first day of the applicable calendar quarter beginning with January 1, 2012. Advisor may elect in its sole discretion to defer the receipt of all or a
portion of the Annual Management Fee. Any portion of the Annual Management Fee accrued or deferred pursuant to this provision shall be payable immediately prior to an initial public offering of the equity securities of the Company or any of its
affiliates or a Sale of the Company, where “Sale of the Company” means a sale, directly or indirectly, of the Company to an independent third party or group of independent third parties pursuant to which such party or parties
(i) acquire capital stock of the Company possessing the voting power under normal circumstances to elect a majority of the Board (whether by merger, consolidation or sale or transfer of the Company’s capital stock or otherwise),
(ii) acquire or obtain an exclusive license to all or substantially all of the Company’s assets determined on a consolidated basis, or (iii) a direct or indirect initial public offering of the Company. If, after the date of this
Agreement, the Company or any of its affiliates consummates the acquisition of any other business, company, product line or enterprise (each an “Add-On Acquisition”), then Advisor and the board of directors of the Company shall,
prior to the consummation of such Add-On Acquisition, determine whether and to what extent the amounts payable pursuant to this Section 4 shall be increased as a result thereof. Any increase shall be evidenced by a written supplement to
this Agreement signed by the Company and Advisor. In the case of a Sale of the Company, the Company shall pay a lump sum amount equal to the net present value (using a discount rate equal to the then prevailing yield on U.S. Treasury securities of
like maturity) of the Annual Management Fees that would have been payable to Advisor with respect to the period from the date of such Sale of the Company until the end of the Term in effect immediately prior to such Sale of the Company. 

5. Expenses. The Company shall reimburse Advisor for such reasonable travel expenses and other reasonable out-of-pocket fees and expenses as may be incurred by Advisor in connection with the rendering of services hereunder. In addition, the Company shall pay and hold Advisor
harmless against liability for the payment of all out-of-pocket expenses (including the fees and expenses of legal counsel, accountants or other advisors) arising in
connection with (a) the preparation, negotiation and execution of this Agreement, the Sale and Purchase Agreement and the other agreements contemplated hereby or thereby, (b) any proposed or completed merger, sale, recapitalization or
other transaction involving the Company or any of its affiliates, (c) any amendments or waivers (whether or not the same become effective) under or in respect of this Agreement, the Sale and Purchase Agreement or the other agreements
contemplated hereby or thereby (including, without limitation, in connection with any proposed merger, sale or recapitalization of the Company or its affiliates), (d) the interpretation, investigation and enforcement of the rights granted under
this Agreement, the Sale and Purchase Agreement or the other agreements contemplated hereby or thereby, (e) any filing with any governmental agency with respect to any direct or indirect investment by Advisor or its affiliates in the Company or
its affiliates or any other filing with any governmental agency with respect to the Company or its affiliates that mentions Advisor or any of its affiliates owning direct or indirect interests in the Company or its affiliates and (f) any other
transaction, claim or event which Advisor or any of its affiliates owning interests in the Company believes affects the Company or its affiliates (or Advisor’s or any of its affiliates’ investment(s) therein) and as to which Advisor or
such affiliate(s) seeks advice of counsel.

 6. Restrictions on Payments. 

(a) Notwithstanding any provision herein to the contrary, for so long as the obligations under the Credit Agreement are outstanding, if an
Event of Default (as defined in the Credit Agreement) exists and is continuing or would result from a payment of any Annual Management Fee or other fee hereunder and, as a result, the Company is prohibited under the Credit Agreement from making the
payment of any Annual Management Fee or other fee hereunder, Advisor shall defer receipt of the Annual Management Fee or other fee hereunder until such Event of Default has been cured or waived, or otherwise ceases to exist. “Credit
Agreement” means that certain Credit Agreement, dated as of the date hereof, by and between, among others, the Company, Icicle Acquisition Holding, B.V., Ichor Systems, Inc., Precision Flow Technologies, Silicon Valley Bank as
administrative agent, issuing lender and swingline lender, and the lenders party thereto from time to time, as the same may be amended, restated, supplemented, refinanced or otherwise modified from time to time in accordance with its terms. 

(b) Any Annual Management Fees or other fees due and payable under this Agreement which are not paid as a result of the limitations set forth
in Section 6(a) above shall be accrued as an obligation of the Company, shall accrue interest at a rate equal to 12% per annum, compounded quarterly, and shall be paid at the earliest date that the Company reasonably anticipates
that the making of such payment will not be prohibited under the Credit Agreement or that the making of such payment will not cause material harm to the Company. The foregoing provision is intended to comply with proposed guidance issued by the
Internal Revenue Service under Sec. 409A of the Internal Revenue Code of 1986, as amended (the “Code”), in order to avoid the acceleration of any tax, or the imposition of any penalty, under Code Sec. 409A with respect to the
payment of fees pursuant to this Agreement. The parties hereto agree to modify the foregoing provisions of this Section 6(b) to comply with any future guidance issued under Code Sec. 409A to the extent necessary to avoid the acceleration
of any tax, or the imposition of any penalty, under Code Sec. 409A with respect to the payment of fees pursuant to this Agreement. 
 7.
Term. This Agreement shall continue in effect until the tenth anniversary of the Effective Date; provided that this Agreement shall be automatically extended on such date for a one-year period of time and annually thereafter in each case for
an additional one-year period of time unless the Company or Advisor provides written notice of its desire not to automatically extend the term of this Agreement to the other party hereto at least 90 days prior to an expiration date; and provided
further, however, that (a) Advisor may cause this Agreement to terminate at any time and (b) this Agreement will terminate automatically upon an initial public offering of the equity securities of the Company or its affiliates or a Sale of
the Company unless the Company and Advisor determine otherwise (the period on and after the date hereof through the termination hereof being referred to herein as the “Term”); and provided further, that (x) each of Sections 8
(Liability), 9 (Indemnification), 18 (Choice of Law) and 19 (Mutual Waiver of Jury Trial) hereof (whether in respect of or relating to services rendered during or after the Term) will survive any termination of this Agreement to the maximum extent
permitted under applicable law and (y) any and all accrued and unpaid obligations of the Company owed hereunder will be paid promptly upon any termination of this Agreement. At the end of the Term, all obligations of Advisor under this
Agreement will terminate and any subsequent services rendered by Advisor to the Company will be separately compensated. 
 8.
Liability. Neither Advisor nor any of its direct or indirect affiliates, partners, members, employees or agents shall be liable to the Company or its affiliates for any loss, liability, damage or expense arising out of or in connection with
the performance of services contemplated by this Agreement, unless such loss, liability, damage or expense shall be proven to result directly from Advisor’s willful misconduct and in no event shall the aggregate liability of any of the
foregoing with respect to this Agreement or any services provided hereunder exceed the fees actually received by Advisor pursuant to 

  
 3 

 
this Agreement. Advisor makes no representations or warranties, express or implied, in respect of the services to be provided hereunder by Advisor or any of its partners, members or employees.
Except as Advisor may otherwise agree in writing after the date hereof: (a) Advisor shall have the right to, and shall have no duty (contractual or otherwise) not to, directly or indirectly: (i) engage in the same or similar business
activities or lines of business as the Company or its affiliates and (ii) do business with any client or customer of the Company or its affiliates; (b) neither Advisor nor any officer, director, employee, partner, member, affiliate or
associated entity thereof shall be liable to the Company or its affiliates for breach of any duty (contractual or otherwise) by reason of any such activities or such person’s or entity’s participation therein; and (c) in the event
that Advisor acquires knowledge of a potential transaction or other matter that may be a corporate opportunity for both the Company or any of its affiliates, on the one hand, and Advisor, on the other hand, or any other person or entity, Advisor
shall have no duty (contractual or otherwise) to communicate or present such corporate opportunity to the Company or its affiliates and, notwithstanding any provision of this Agreement to the contrary, shall not be liable to the Company or its
affiliates for breach of any duty (contractual or otherwise) by reasons of the fact that Advisor directly or indirectly pursues or acquires such opportunity for itself, directs such opportunity to another person or entity, or does not present such
opportunity to the Company or its affiliates. In no event will any of the parties hereto be liable to any other party hereto for any indirect, special, incidental or consequential damages, including lost profits or savings, whether or not such
damages are foreseeable, or in respect of any liabilities relating to any third party claims (whether based in contract, tort or otherwise), except as set forth in Section 9 below. 

9. Indemnification. 
 (a)
The Company agrees to defend, protect, indemnify and hold harmless Advisor, its partners, members, affiliates, officers, managers, directors, employees and agents (the “Indemnitees”) from and against any and all actions, causes of
action, losses, liabilities, suits, claims, costs, damages, penalties, fees and expenses (irrespective of whether any such Indemnitee is a party to the action for which indemnification hereunder is sought), including reasonable attorneys’ fees
and disbursements, incurred by the Indemnitees or any of them as a result of, arising from or relating to (i) this Agreement and any performance hereunder, (ii) any transaction to which any of the Company or any of its affiliates is a
party or any other circumstance, event or development with respect to any of the Company or any of its affiliates, or (iii) any claim made or cause of action against Advisor or any of its affiliates that relates directly or indirectly to the
Company or its affiliates or Advisor’s (or any of its affiliates’) investment in the Company or its affiliates, in each case except as a result of Advisor’s willful misconduct. 

(b) The Company hereby acknowledges that the Indemnitees have certain rights to indemnification, advancement of expenses and/or insurance
provided by the investment funds managed by Advisor, and certain of their affiliates (collectively, the “Fund Indemnitors”). The Company hereby agrees with respect to any indemnification, hold harmless obligation, expense
advancement or reimbursement provision or any other similar obligation whether pursuant to or with respect to this Agreement, the organizational documents of the Company or any other agreement, as applicable, (i) that the Company is the
indemnitor of first resort (i.e., its obligations to the Indemnitees are primary and any obligation of the Fund Indemnitors to advance expenses or to provide indemnification for the same expenses or liabilities incurred by any Indemnitees are
secondary), (ii) that the Company shall be required to advance the full amount of expenses incurred by any Indemnitee and shall be liable for the full amount of all costs, damages, penalties, fees and expenses paid in settlement to the extent
legally permitted and as required by the terms of this Agreement, the organizational documents of the Company or any other agreement, as applicable, without regard to any rights any Indemnitee may have against the Fund Indemnitors, and
(iii) that the Company 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 

  
 4 

 
payment by the Fund Indemnitors on behalf of any Indemnitee with respect to any claim for which any 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 any Indemnitee against the Company. The Company agrees that the Fund Indemnitors are express
third-party beneficiaries of the terms of this Section 9(b). 
 10. Independent Contractor. Advisor shall perform
services hereunder as an independent contractor, retaining control over and responsibility for its own operations and personnel. Neither Advisor nor its directors, officers, partners, members or employees shall be considered employees or agents of
the Company as a result of this Agreement, nor shall any of them have authority to contract in the name of or bind the Company, except as otherwise expressly agreed. 

11. Notices. All notices, demands and other communications to be given or delivered under or by reason of the provisions of this
Agreement shall be in writing and shall be deemed to have been given (a) when personally delivered or sent by facsimile (with hard copy to follow), (b) one business day following the day when deposited with a reputable and established
overnight express courier (charges prepaid) or (c) five days following mailing by certified or registered mail, postage prepaid and return receipt requested. Unless another address is specified in writing, notices, demands and communications to
the Company and Advisor shall be sent to the addresses indicated below (or at such other address as shall be given in writing by one party to the other):

12. Entire Agreement; Modification. This Agreement and those documents expressly referred to herein contain the complete and entire
understanding and agreement of Advisor and the Company with respect to the subject matter hereof and supersede all prior and contemporaneous 

  
 5 

 
understandings, conditions and agreements, oral or written, express or implied, respecting the engagement of Advisor in connection with the subject matter hereof. The provisions of this Agreement
may be amended, modified and/or waived only with the prior written consent of the Company and Advisor. 
 13. Waiver of Breach. The
waiver by either party of a breach of any provision of this Agreement by the other party shall not operate or be construed as a waiver of any subsequent breach of that provision or any other provision hereof. 

14. Assignment. Neither Advisor nor the Company may assign its rights or obligations under this Agreement without the express written
consent of the other, except that Advisor may assign its rights and obligations to any of its affiliates. 
 15. Successors. This
Agreement and all the obligations and benefits hereunder shall bind and inure to the respective successors and permitted assigns of the parties. 

16. Counterparts. This Agreement may be executed by each party hereto in separate counterparts, each of which when so executed shall be
deemed an original and both of which taken together shall constitute one and the same agreement. 
 17. Delivery by Facsimile, E-mail or
Comparable Electronic Transmission. This Agreement, the agreements referred to herein and each other agreement or instrument entered into in connection herewith or therewith, or contemplated hereby or thereby, and any amendments hereto or
thereto, to the extent signed and delivered by means of a facsimile machine, e-mail or comparable electronic transmission shall be treated in all manner and respects as an original agreement or instrument and shall be considered to have the same
binding legal effect as if it were the original signed version thereof delivered in person. At the request of any party hereto or to any other such agreement or instrument, each other party hereto or thereto shall reexecute original forms thereof
and deliver them to all other parties. No party hereto or to any other such agreement or instrument shall raise the use of a facsimile machine, e-mail or comparable electronic transmission to deliver a signature or the fact that any signature or
agreement or instrument was transmitted or communicated through the use of a facsimile machine, e-mail or comparable electronic transmission as a defense to the formation or enforceability of a contract and each such party forever waives any such
defense. 
 18. Choice of Law. This Agreement shall be governed by and construed in accordance with the domestic laws of the State of
Delaware, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware.

 19. MUTUAL WAIVER OF JURY TRIAL. BECAUSE DISPUTES ARISING IN CONNECTION WITH COMPLEX TRANSACTIONS ARE MOST QUICKLY AND
ECONOMICALLY RESOLVED BY AN EXPERIENCED AND EXPERT PERSON AND THE PARTIES WISH APPLICABLE STATE AND FEDERAL LAWS TO APPLY (RATHER THAN ARBITRATION RULES), THE PARTIES DESIRE THAT THEIR DISPUTES BE RESOLVED BY A JUDGE APPLYING SUCH APPLICABLE LAWS.
THEREFORE, TO ACHIEVE THE BEST COMBINATION OF THE BENEFITS OF THE JUDICIAL SYSTEM AND OF ARBITRATION, EACH PARTY TO THIS AGREEMENT HEREBY WAIVES ALL RIGHTS TO TRIAL BY JURY IN ANY ACTION, SUIT OR PROCEEDING BROUGHT TO RESOLVE ANY DISPUTE BETWEEN THE
PARTIES HERETO, WHETHER ARISING IN CONTRACT, TORT OR OTHERWISE, ARISING OUT OF, CONNECTED WITH, RELATED OR INCIDENTAL TO THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREBY AND/OR THE RELATIONSHIP ESTABLISHED AMONG THE PARTIES HEREUNDER. 

  
 6 

 20. Attorneys’ Fees. If any action at law or in equity is necessary to enforce or
interpret the terms of this Agreement or to protect the rights obtained hereunder, the prevailing party shall be entitled to its reasonable attorneys’ fees, including attorneys’ fees on appeal, costs, and disbursements in addition to any
other relief to which it may be entitled.
