Lenders and the Loan Parties hereby waives the notice requirements of Section 9.06(a) in respect of such resignation. 

(b) Survival. The provisions of Article IX and Section 11.04 of the Credit Agreement shall continue in effect for
the benefit of Resigning Agent, its sub agents, and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while (i) Resigning Administrative Agent was acting as Administrative Agent,
(ii) Resigning L/C 

 
Issuer was acting as L/C Issuer or (iii) Resigning Swingline Lender was acting as Swingline Lender. Solely to the extent any Letters of Credit are outstanding as of the Resignation Effective
Date, Resigning L/C Issuer hereby retains all rights, powers, privileges and duties of L/C Issuer under the Credit Agreement with respect to all Letters of Credit outstanding as of the Resignation Effective Date and all L/C Obligations with respect
thereto, including the right to require the Lenders to make Base Rate Loans or fund risk participations in Unreimbursed Amounts pursuant to Section 2.03(c) of the Credit Agreement. Further, solely to the extent any Swingline Loans are
outstanding as of the Resignation Effective Date, Resigning Swingline Lender hereby retains all rights of Swingline Lender provided for under the Credit Agreement with respect to Swingline Loans made by it and outstanding as of the Resignation
Effective Date, including the right to require the Lenders to make Base Rate Loans or fund risk participations in outstanding Swingline Loans pursuant to Section 2.04(c). 

1.2 Appointment of Successor Agent. Pursuant to Section 9.06 of the Credit Agreement and subject to the satisfaction of the
conditions precedent set forth in Article IV, each of the Lenders party hereto, constituting the Required Lenders, hereby appoints SVB as Administrative Agent, L/C Issuer and Swingline Lender under the Credit Agreement and the other Loan
Documents (in such capacities, “Successor Agent”). 
 1.3 Acceptance of Appointment by Successor Agent.
 
 (a) Acceptance of Appointment by Successor Agent. Subject to the satisfaction of the conditions precedent
set forth in Article V, Successor Agent hereby accepts its appointment as Administrative Agent, L/C Issuer and Swingline Lender under the Credit Agreement and the other Loan Documents and shall hereby (i) succeed to and, from and after
the Resignation Effective Date, be vested with all the rights, powers, privileges, duties and protections of Administrative Agent, L/C Issuer and Swingline Lender under the Credit Agreement and each of the other Loan Documents, in each case with
like effect as if Successor Agent were originally named as Administrative Agent, L/C Issuer and Swingline Lender under the Credit Agreement and each of the other Loan Documents and (ii) issue letters of credit in substitution for the Letters of
Credit, if any, outstanding on the Resignation Effective Date or make other arrangements satisfactory to Resigning L/C Issuer to effectively assume the obligations of Resigning L/C Issuer with respect to such Letters of Credit. From and after the
Resignation Effective Date, except (x) as provided in Section 3.01(g) of the Credit Agreement and (y) for any rights to indemnity payments or other amounts owed to Resigning Agent as of the Resignation Effective Date, all payments,
communications and determinations provided to be made by, to or through Administrative Agent shall instead be made to Successor Agent. 

(b) Exculpation of Successor Agent Without limiting the generality of Article X of the Credit Agreement, (i) none
of Successor Agent, its sub agents, and their respective Related Parties, shall have liability to any Loan Party or any other Person with respect to actions taken or omitted to be taken prior to the Resignation Effective Date by (A) Resigning
Administrative Agent, its sub agents, and their respective Related Parties as Administrative Agent, (B) Resigning L/C Issuer, its sub agents, and their respective Related Parties as L/C Issuer and/or (C) Resigning Swingline Lender, its sub
agents, and their respective Related Parties as Swingline Lender and (ii) none of Resigning Agent, its sub agents, and their respective Related Parties, shall have liability to the Lenders, Loan Parties or any other Person with respect to
actions taken or omitted to be taken by Successor Agent, its sub agents, and their respective Related Parties, as Administrative Agent, L/C Issuer or Swingline Lender occurring from and after the Resignation Effective Date.

 1.4 Bailee; Perfection and Assignment Documents.  

(a) Bailee. Notwithstanding anything herein to the contrary, Resigning Administrative Agent shall continue to hold
collateral security on behalf of the Lenders and the L/C Issuer pursuant to the Loan Documents until such time as the Perfection and Assignment Documents (defined below), including those set forth on Schedule II hereto, have been executed,
delivered and, as applicable, recorded, in each case as reasonably determined by Successor Agent (the “Perfection Effective Date”). Without limiting the generality of the foregoing, any and all references to “Bank of
America” on any publicly filed document, to the extent such filing relates to liens and security interests assigned to the Successor Agent hereby and until the Perfection Date, with respect to such liens and security interests, constitute
a reference to “Bank of America” as the nominee and collateral representative of SVB, as Successor Agent. Successor Agent hereby appoints Resigning Administrative Agent as its agent solely for the purpose of perfecting and continuing the
perfection of Successor Agent’s liens in that part of the Collateral that is in the possession or control of Resigning Administrative Agent (or in the possession or control of its agents or bailees), or is the subject of any perfection
instruments in favor of Resigning Administrative Agent or other agreements or documents pertaining to the Collateral in favor of Resigning Administrative Agent (such Collateral, the “Pledged Collateral”) until the Perfection
Effective Date. Resigning Administrative Agent hereby accepts such appointment and agrees to serve as perfection agent solely for the purpose of perfecting and continuing the perfection of Successor Agent’s liens in such Pledged Collateral
until the Perfection Effective Date. It is understood that Resigning Administrative Agent shall have no duties or responsibilities under this Section 1.4 to Successor Agent, any Lender or any Loan Party except as is expressly otherwise
provided herein. All of such liens and security interests in the Pledged Collateral shall in all respects be continuing and in effect following execution and delivery of this Agreement and are hereby ratified and reaffirmed by the Loan Parties. 

(b) Perfection and Assignment Documents. Resigning Administrative Agent shall (i) (A) execute and deliver such
instruments as may be prepared by Successor Agent and are in form and substance reasonably satisfactory to Resigning Administrative Agent, and (B) do such other things as Successor Agent may reasonably request, in each case, so as to more fully
and certainly vest and confirm upon Successor Agent the rights, powers, privileges, obligations, duties and protections described in Section 1.3 and (ii) (A) assign or otherwise transfer to Successor Agent all (1) UCC
financing statements and (2) other perfection documentation (including, without limitation, an assignment of record of all publicly recorded perfection instruments), in each case, (x) with respect to liens encumbering the Pledged
Collateral securing the Obligations and (y) pursuant to such instruments as may be prepared by Successor Agent in form and substance reasonably satisfactory to Resigning Administrative Agent and (B) physically deliver to Successor Agent
all possessory Pledged Collateral, if any, held by Resigning Administrative Agent with respect to liens encumbering the Pledged Collateral securing the Obligations. All of the instruments and documentation described in this Section 1.4
(collectively, the “Perfection and Assignment Documents”) shall be prepared and (if applicable) recorded publicly, at the sole cost and expense of the Loan Parties. Each Loan Party agrees (i) to promptly take such action, upon
the reasonable request of Successor Agent, as is necessary to carry out the intent of this Agreement, including, without limitation, the execution and delivery of any Perfection and Assignment Document, and (ii) that Successor Agent shall
receive from Borrower all costs and expenses of Successor Agent invoiced as of the date hereof in connection with the preparation, execution, delivery, filing and/or recordation of this Agreement and the Perfection and Assignment Documents.

 ARTICLE II 

WAIVER 
 Each Loan Party,
its respective successors-in-title, legal representatives and assignees and, to the extent the same is claimed by right of, through or under such Loan Party, for their respective past, present and future employees, agents, representatives, officers,
directors, shareholders, and trustees, do hereby and shall be deemed to have forever remised, released and discharged Resigning Agent, its Affiliates, and any of the successors-in-title, legal representatives and assignees, past, present and future
officers, directors, shareholders, trustees, agents, employees, consultants, experts, advisors, attorneys and other professionals and all other persons and entities to whom Resigning Agent, or any of its Affiliates would be liable if such persons or
entities were found to be liable to any Loan Party, (collectively hereinafter the “Resigning Agent Parties”), from any and all manner of action and actions, cause and causes of action, claims, charges, demands, counterclaims, suits,
debts, dues, sums of money, accounts, reckonings, bonds, bills, specialties, covenants, contracts, controversies, damages, judgments, expenses, executions, liens, claims of liens, claims of costs, penalties, attorneys’ fees, or any other
compensation, recovery or relief on account of any liability, obligation, demand or cause of action of whatever nature, whether in law, equity or otherwise (including without limitation those arising under 11 U.S.C. §§ 541-550 and interest
or other carrying costs, penalties, legal, accounting and other professional fees and expenses, and incidental, consequential and punitive damages payable to third parties), whether known or unknown, fixed or contingent, joint and/or several,
secured or unsecured, due or not due, primary or secondary, liquidated or unliquidated, contractual or tortious, direct, indirect, or derivative, asserted or unasserted, foreseen or unforeseen, suspected or unsuspected, now existing, heretofore
existing or which may heretofore accrue against any of the Resigning Agent Parties, whether held in a personal or representative capacity, and which are based on any act, fact, event or omission or other matter, cause or thing occurring at or from
any time prior to and including the Resignation Effective Date in any way, directly or indirectly arising out of, connected with or relating to any of the Loan Documents, and the transactions contemplated thereby, and all other agreements,
certificates, instruments and other documents and statements (whether written or oral) related to any of the foregoing. 
 Except for the
obligations, assignments and agreements set forth herein, each Loan Party hereby warrants, represents and agrees that they are fully aware of the provisions of California Civil Code Section 1542, which provides as follows: 

“A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS OR HER FAVOR AT THE TIME OF
EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM OR HER MUST HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH THE DEBTOR.” 
 Each Loan
Party hereby agrees that California Civil Code Section 1542 is expressly incorporated into this Agreement and thereupon voluntarily waives the provisions of California Civil Code Section 1542, and any other similar law, as to any and all
claims, demands, causes of action, or charges, known or unknown, and further agrees that this waiver is a material aspect of the consideration for entering into this Agreement. 

Each Loan Party hereby knowingly, voluntarily, intentionally and expressly waives and relinquishes any and all rights and benefits that it may
have under any provision of any jurisdiction that provides that a general release does not extend to claims which the creditor does not know or suspect to exist in the creditor’s favor at the time of executing the release, which if known by the
creditor must have materially affected the creditor’s settlement with the debtor, or any law of the any state or territory of the United States or any foreign country or principle of common law that is similar or analogous. Each Loan Party
hereby agrees and acknowledges that the foregoing waiver was separately bargained for. This waiver is an essential term of this Agreement, without which Resigning Agent would not have agreed to execute this Agreement. The release contained herein
and the related provisions shall survive the termination of the Credit Agreement and payment in full of the Obligations.

 ARTICLE III 

CONTINUING INDEMNITIES 

3.1 Continuing Indemnities of the Loan Parties. The indemnification and reimbursement provisions of the Loan Documents,
including, without limitation Sections 3.01, 11.02(e) and 11.04 of the Credit Agreement, shall continue to be effective for the benefit of, and enforceable by, Resigning Agent, its sub agents and their respective Related Parties and with respect to
actions taken or omitted to be taken by any of them and other events and conditions occurring prior to the Resignation Effective Date, or in accordance with this Agreement (such provision, collectively, the “Continuing
Indemnities”). As of the Resignation Effective Date, Resigning Agent hereby confirms that it has not received notice of and has no actual knowledge of any pending or overtly threatened claims against Resigning Agent or any of its sub agents
or their respective Related Parties, or incurred any losses, obligations, fees, expenses or charges in connection therewith, and with respect to which it would be entitled to reimbursement or indemnity under the Continuing Indemnities. 

3.2 Reimbursement Obligation of the Lenders. To the extent the Loan Parties shall for any reason fail to indefeasibly pay any
amount required hereunder to be paid to the Resigning Agent, each Lender severally agrees to pay to Resigning Agent, on behalf of Resigning Agent, its sub agents and their respective Related Parties, as the case may be, such Lender’s pro rata
share (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought based on each Lender’s share of the Total Credit Exposure at such time) of such unpaid amount (including any such unpaid amount in respect
of a claim asserted by such Lender), such payment to be made severally among them based on such Lender’s Applicable Percentage (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought). 

ARTICLE IV 
 COMMITMENTS

 Each Resigning Lender, as of the Resignation Effective Date, has elected to terminate in full its Commitment under the Credit
Agreement. As a result of this action after giving effect to such terminations on the Resignation Effective Date, the Commitment of all of the Lenders shall be $72,500,000 and the Resigning Lenders shall cease to be Lenders under the Loan Documents.
Schedule 1.01(b) to the Credit Agreement is hereby deleted in its entirety and replaced with Schedule 1.01(b) attached hereto as Exhibit A. 

ARTICLE V
