(b) Pledgor shall pay to Bank, in US dollars, the customary issuance, presentation, amendment and other processing fees, and other standard costs and charges, of Bank relating to letters of credit as from time to time in effect. Such customary fees and standard costs and charges are due and payable on demand and are nonrefundable.

7. Costs. All reasonable advances, charges, costs and expenses, including reasonable attorneys’ fees, incurred or paid by the Bank in exercising any right, power or remedy conferred by this Agreement or in the enforcement thereof (collectively, the “Collateral Costs”), shall become a part of the Obligations secured hereunder and shall be paid to the Bank by Pledgor immediately upon demand, with interest thereon if not paid within three (3) business days of demand at an annual rate equal to 2.00%. Such costs and attorneys’ fees shall include the allocated cost of in-house counsel to the extent permitted by law.

8. Financial Statements. The Pledgor shall deliver to the Bank, as soon as available, but in any event within forty-five days after the end of each fiscal quarter of the Pledgor (or with respect to the last fiscal quarter of any fiscal year of Pledgor, within sixty days after the end of such fiscal quarter), commencing with the fiscal quarter ending December 31, 2017, an internally prepared consolidated balance sheet of the Pledgor and its subsidiaries as of the end of such fiscal quarter and the related internally prepared consolidated statements of income or operations for such fiscal quarter and for the portion of the Pledgor’s fiscal year then ended, and the related consolidated statements of changes in shareholders’ equity and cash flows for the portion of the Pledgor’s fiscal year then ended, all in reasonable detail and certified by the chief executive officer, chief financial officer, treasurer or controller of the Pledgor as fairly presenting the financial condition, results of operations, shareholders’ equity and cash flows of the Pledgor and its subsidiaries for period of time covered thereby; provided, that, foregoing financial statements shall not be required for any fiscal quarter when the Pledgor has filed financial statements for such fiscal quarter with the SEC under Section 13 or 15(d) of the Securities Exchange Act of 1934.

9. Events of Default. To the extent permitted by law, at the option of Bank without necessity of demand or notice, all or any part of the Obligations of Pledgor shall immediately become due and payable irrespective of any agreed maturity upon the happening of any of the following events (“Events of Default”); provided, however, that all Obligations of Pledgor automatically shall become

immediately due and payable if a bankruptcy petition is filed by the Pledgor or an involuntary bankruptcy petition is filed against the Pledgor that is not dismissed within 60 days of filing: (a) failure to keep or perform any of the terms or provisions of this Agreement or the Obligations within 20 days of Pledgor receiving written notice from Bank of such failure; (b) default in the payment of principal, interest or fees with respect to any Obligations (if any) within three (3) business days when due; (c) the levy of any attachment, execution or other process against the Deposit Account; (d) the insolvency, commission of an act of bankruptcy, general assignment for the benefit of creditors, filing of any petition in bankruptcy or for relief under the provisions of the Bankruptcy Code by the Pledgor, or the filing of any petition in bankruptcy or for relief under the provisions of the Bankruptcy Code against the Pledgor that is not dismissed within 60 days of filing. Upon the happening of any of the foregoing specified events, any agreement for further financial accommodation by Bank shall terminate at its option.

11. Waivers. Pledgor waives any right to require Bank to (a) proceed against any person, (b) proceed against or exhaust any collateral, or (c) pursue any other remedy in Bank’s power; and waive any defense arising by reason of any disability or other defense of any other person, or by reason of the cessation from any cause whatsoever of the liability of any other person. Until the Obligations have been paid in full and the Letters of Credit have expired or been cancelled in accordance with the Bank’s requirements, Pledgor waives any right of subrogation, reimbursement, indemnification, and contribution (contractual, statutory or otherwise), including without limitation, any claim or right of subrogation under

the Bankruptcy Code (Title 11, United States Code) or any successor statute, arising from the existence or performance of this Agreement, and Pledgor waives any right to enforce any remedy which Bank now has or may hereafter have against any other person, and waives any benefit of, and any right to participate in, any security now or hereafter held by Bank.

12. Continuing Agreement. This Agreement shall continue to be effective or be automatically reinstated, as the case may be, if at any time payment, in whole or in part, of any of the Obligations is rescinded or must otherwise be restored or returned by the Bank as a preference, fraudulent conveyance or otherwise under any Debtor Relief Law, all as though such payment had not been made; provided that in the event payment of all or any part of the Obligations is rescinded or must be restored or returned, all reasonable costs and expenses (including without limitation any reasonable legal fees and disbursements) incurred by the Bank in defending and enforcing such reinstatement shall be deemed to be included as a part of the Obligations.

13. Continuing Powers. Until all Obligations shall have been paid in full all rights, powers and remedies granted to Bank hereunder shall continue to exist and may be exercised by Bank at the time specified hereunder irrespective of the fact that the Obligations or any part thereof may have become barred by any statute of limitations, or that the liability of the Pledgor may have ceased.

14. Other Rights. The rights, powers and remedies given to Bank by this Agreement shall be in addition to all rights, powers and remedies given to Bank by virtue of any statute or rule of law. Any forbearance or failure or delay by Bank in exercising any right, power or remedy hereunder shall not be deemed to be a waiver of such right, power or remedy, and any single or partial exercise of any right, power or remedy hereunder shall not preclude the further exercise thereof; and every right, power and remedy of Bank shall continue in full force and effect until such right, power or remedy is specifically waived by an instrument in writing executed by Bank.

(a) Cash in the Deposit Account to secure the Obligations shall be released promptly following the determination by the Bank that the principal balance in the Deposit Account exceeds the amount of the Obligations; provided, however, the Pledgor and the Bank may agree that cash in the Deposit Account shall not be released but instead held to support future anticipated Obligations.
