to be performed or fulfilled under or pursuant to this Master Security Agreement, the Agent may, at its option without waiving its right to enforce this Master Security Agreement according to its terms, immediately or at any time thereafter and
without notice to any Assignor, perform or fulfill the same or cause the performance or fulfillment of the same for each Assignor’s joint and several account and at each Assignor’s joint and several cost and expense, and the cost and
expense thereof (including reasonable attorneys’ fees) shall be added to the Obligations and shall be payable on demand with interest thereon at the highest rate permitted by law, or, at the Agent’s option, debited by the Agent from any
other deposit accounts in the name of any Assignor and controlled by the Agent. 
 8. Each Assignor hereby appoints the Agent, or any other Person whom the
Agent may designate as such Assignor’s attorney, with power to: (a)(i) execute any security related documentation on such Assignor’s behalf and to supply any omitted information and correct patent errors in any documents executed by such
Assignor or on such Assignor’s behalf; (ii) to file financing statements against such Assignor covering the Collateral (and, in connection with the filing of any such financing statements, describe the Collateral as “all assets and

against account debtors, schedules and assignments of accounts receivable, 

 
notices of assignment, financing statements and other public records, verifications of accounts receivable and notices to or from account debtors; and
(iv) to do all other things the Agent deems necessary to carry out the terms of Section 2 of this Master Security Agreement and (b) upon the occurrence and during the continuance of an Event of Default; (v) endorse such
Assignor’s name on any checks, notes, acceptances, money orders, drafts or other forms of payment or security that may come into the Agent’s possession; (vi) sign such Assignor’s name on any invoice or bill of lading relating to
any accounts receivable, drafts against account debtors, schedules and assignments of accounts receivable, notices of assignment, financing statements and other public records, verifications of accounts receivable and notices to or from account
debtors; (vii) verify the validity, amount or any other matter relating to any accounts receivable by mail, telephone, telegraph or otherwise with account debtors; (viii) do all other things necessary to carry out this Agreement, any other
Document and all other related documents; and (ix) notify the post office authorities to change the address for delivery of such Assignor’s mail to an address designated by the Agent, and to receive, open and dispose of all mail addressed
to such Assignor. Each Assignor hereby ratifies and approves all acts of the attorney and neither the Agent nor the attorney will be liable for any acts of commission or omission, nor for any error of judgment or mistake of fact or law other than
gross negligence or willful misconduct (as determined by a court of competent jurisdiction in a final and non-appealable decision). This power being coupled with an interest, is irrevocable so long as any Obligations remains unpaid. 
 9. No delay or failure on the Agent’s part in exercising any right, privilege or option hereunder shall operate as a waiver of such or of any other right,
privilege, remedy or option, and no waiver whatever shall be valid unless in writing, signed by the Agent and then only to the extent therein set forth, and no waiver by the Agent of any default shall operate as a waiver of any other default or of
the same default on a future occasion. The Creditor Parties’ books and records containing entries with respect to the Obligations shall be admissible in evidence in any action or proceeding, shall be binding upon each Assignor for the purpose
of establishing the items therein set forth and shall constitute prima facie proof thereof. The Agent shall have the right to enforce any one or more of the remedies available to the Agent, successively, alternately or concurrently. Each Assignor
agrees to join with the Agent in executing such documents or other instruments to the extent required by the UCC in form satisfactory to the Agent and in executing such other documents or instruments as may be required or deemed necessary by the
Agent for purposes of affecting or continuing the Agent’s security interest in the Collateral. 
 10. The Assignors shall jointly and severally pay all
of the Agent’s and each other Creditor Party’s out-of-pocket costs and expenses, including reasonable fees and disbursements of in-house or outside counsel and appraisers, in connection with the preparation, execution and delivery of the
Documents, and in connection with the prosecution or defense of any action, contest, dispute, suit or proceeding concerning any matter in any way arising out of, related to or connected with any Document. The Assignors shall jointly and severally
also pay all of the Agent’s and each other Creditor Party’s reasonable fees, charges, out-of-pocket costs and expenses, including fees and disbursements of counsel and appraisers, in connection with (a) the preparation, execution and
delivery of any waiver, any amendment thereto or consent proposed or executed in connection with the transactions contemplated by any of the Documents, (b) the Agent’s obtaining performance of the Obligations under the Documents,
including, but not limited to the enforcement or defense of the Agent’s security interests, assignments of rights and liens hereunder as valid perfected security interests, (c) any attempt to inspect, verify, protect, 

 
collect, sell, liquidate or otherwise dispose of any Collateral, (d) any appraisals or re appraisals of any property (real or personal) pledged to the

each other Creditor Party’s customary bank charges for all bank services (including wire transfers) performed or caused to be performed by the Agent or any other Creditor Party for any Assignor at any Assignor’s request or in connection

demand and shall be secured by the Collateral. If any tax by any nation or government, any state or other political subdivision thereof, and any agency, department or other entity exercising executive, legislative, judicial, regulatory or
administrative functions of or pertaining to government (each, a “Governmental Authority”) is or may be imposed on or as a result of any transaction betweenany Assignor, on the one hand, and the Agent and/or any other Creditor Party
on the other hand, which the Agent and/or any other Creditor Party is or may be required to withhold or pay (including, without limitation, as a result of a breach by any Assignor), the Assignors hereby jointly and severally indemnify and holds the
Agent and each other Creditor Party harmless in respect of such taxes, and each Assignor will repay to the Agent or such other Creditor Party the amount of any such taxes which shall be charged to the Assignors’ account; and until the Assignors
shall furnish the Agent and such other Creditor Party with indemnity therefor (or supply the Agent and such other Creditor Party with evidence satisfactory to it that due provision for the payment thereof has been made), the Creditor Parties may
hold without interest any balance standing to each Assignor’s credit (if any) and the Agent shall retain its liens in any and all Collateral.
