(c) Pledged Shares Distributions. Distributions and other payments which are received by the Grantor but which it is not entitled to retain as a result of the operation of subsection (a) or (b) shall be held in trust for the benefit of the Administrative Agent, be segregated from the other property or funds of the Grantor, and be forthwith paid over or delivered to the Administrative Agent in the same form as so received.

For the purpose of enabling the Administrative Agent to exercise its rights under this Section 6 or otherwise in connection with this Agreement, the Grantor hereby (i) constitutes and appoints the Administrative Agent (and any of the Administrative Agent’s officers, employees or agents designated by the Administrative Agent) its true and lawful attorney-in-fact, with full power and authority to execute any notice, assignment, endorsement or other instrument or document, and to do any and all acts and things for and on behalf of the Grantor, which the Administrative Agent may deem necessary or desirable to protect and (provided there exists an Event of Default) collect and realize upon, and to preserve the Pledged Collateral, to enforce the Administrative Agent’s rights with respect to the Pledged Collateral and to accomplish the purposes hereof, and (ii) revokes all previous proxies with regard to the Pledged Collateral and appoints the Administrative Agent as its proxyholder with respect to the Pledged Collateral to attend and vote at any and all meetings of the shareholders of the Companies held on or after the date of this proxy and prior to the termination hereof (in accordance with the terms of Section 6(b) hereof), with full power of substitution to do so and agrees, if so requested, to execute or cause to be executed appropriate proxies therefor. Each such appointment is coupled with an interest and irrevocable so long as the Administrative Agent has any Commitments or the Secured Obligations have not been paid and performed in full. The Grantor hereby ratifies, to the extent permitted by Law, all that the Administrative Agent shall lawfully and in good faith do or cause to be done by virtue of and in compliance with this Section 6.

(f) Proceeds Account. To the extent that any of the Secured Obligations may be contingent, unmatured or unliquidated at such time as there may exist an Event of Default, the Administrative Agent may, at its election, (i) retain the proceeds of any sale, collection, disposition or other realization upon the Pledged Collateral (or any portion thereof) in a special purpose non-interest-bearing restricted deposit account (the “Proceeds Account”) created and maintained by the Administrative Agent for such purpose (as to which the Grantor hereby grants a security interest and which shall constitute part of the Pledged Collateral hereunder) until such time as the Administrative Agent may elect to apply such proceeds to the Secured Obligations, and the Grantor agrees that such retention of such proceeds by the Administrative Agent shall not be deemed strict foreclosure with respect thereto; (ii) in any manner elected by the Administrative Agent, estimate the liquidated amount of any such contingent, unmatured or unliquidated claims and apply the proceeds of the Pledged Collateral against such amount; or (iii) otherwise proceed in any manner permitted by applicable Law. The Grantor agrees that the Proceeds Account shall be a blocked account and that upon the irrevocable deposit of funds into the Proceeds Account, the Grantor shall not have any right of withdrawal with respect to such funds. Accordingly, the Grantor irrevocably waives, until the termination of this Agreement in accordance with Section 22, the right to make any withdrawal from the Proceeds Account and the right to instruct the Administrative Agent to honor drafts against the Proceeds Account.

(g) Application of Proceeds. Subject to subsection (f) above, the cash proceeds actually received from the sale or other disposition or collection of Pledged Collateral, and any other amounts of the Pledged Collateral (including any cash contained in the Pledged Collateral) the application of which is not otherwise provided for herein, shall be applied in the order specified in Section 9.03 of the Credit Agreement. Any surplus thereof which exists after payment and performance in full of the Secured Obligations shall be promptly paid over to the Grantor or otherwise disposed of in accordance with the UCC or other applicable Law. The Grantor shall remain liable to the Administrative Agent for any deficiency which exists after any sale or other disposition or collection of Pledged Collateral.

SECTION 7 Remedies Cumulative. Each and every right, power and remedy hereby specifically given to the Administrative Agent shall be in addition to every other right, power and remedy specifically given to the Administrative Agent under this Agreement, now or hereafter existing at Law, in equity or by statute and each and every right, power and remedy whether specifically herein given or otherwise existing may be exercised from time to time or simultaneously and as often and in such order as may be deemed expedient by the Administrative Agent. All such rights, powers and remedies shall be cumulative and the exercise or the beginning of the exercise of one shall not be deemed a waiver of the right to exercise any other or others. No delay or omission of the Administrative Agent in the exercise of any such right, power or remedy and no renewal or extension of any of the Secured Obligations shall impair any such right, power or remedy or shall be construed to be a waiver of any Default or Event of Default or an acquiescence thereof. No notice to or demand on the Grantor in any case shall entitle it to any other or further notice or demand in similar or other circumstances or constitute a waiver of any of the rights of the Administrative Agent or further action in any circumstances without notice or demand. In the event that the Administrative Agent shall bring any suit to enforce any of its rights hereunder and shall be entitled to judgment, then in such suit the Administrative Agent may recover reasonable expenses, including reasonable attorneys’ fees, and the amounts thereof shall be included in such judgment. The Lien granted hereunder and the rights and remedies of the Administrative Agent with respect to the Liens granted hereunder are granted in conjunction with the pledge granted under the Korean Pledge, and are in addition and supplemental to, and in no way limit or should be construed to limit, those set forth in the Korean Share Pledge or the other Loan Documents or those which are now or hereafter available to the Administrative Agent or any Lender as a matter of law or equity. The exercise by the Administrative Agent of any one or more of the rights, powers or remedies provided for in this Agreement or any of the other Loan Documents, or now or hereafter existing at law or in equity, shall not preclude the simultaneous or later exercise of any or all other rights, powers or remedies.

SECTION 8 Administrative Agent Performance of Grantor Obligations. The Administrative Agent may perform or pay any obligation which the Grantor has agreed to perform or pay under or in connection with this Agreement, and the Grantor shall reimburse the Administrative Agent on demand for any amounts paid by the Administrative Agent pursuant to this Section 8.

SECTION 9 Administrative Agent’s Duties. Notwithstanding any provision contained in this Agreement, the Administrative Agent shall have no duty to exercise any of the rights, privileges or powers afforded to it and shall not be responsible to the Grantor or any other Person for any failure to do so or delay in doing so. Beyond the exercise of reasonable care to assure the safe custody of the Pledged Collateral while held hereunder and the accounting for moneys actually received by the Administrative Agent hereunder, the Administrative Agent shall have no duty or liability to exercise or preserve any rights, privileges or powers pertaining to the Pledged Collateral.

SECTION 10 Reserved.

SECTION 11 Certain Waivers.

(a) The Grantor waives, to the fullest extent permitted by Law, (i) any right of redemption with respect to the Pledged Collateral, whether before or after sale hereunder, and all rights, if any, of marshalling of the Secured Obligations, the Pledged Collateral, or other collateral or security for the Secured Obligations; (ii) any right to require the Administrative Agent (A) to proceed against any Person, (B) to exhaust any other collateral or security for any of the Secured Obligations, (C) to pursue any remedy in the Administrative Agent’s power, or (D) to make or give any presentments, demands for performance, notices of nonperformance, protests, notices of protests or notices of dishonor in connection with any of the Pledged Collateral; and (iii) all claims, damages, and demands against the Administrative Agent arising out of the repossession, retention, sale or application of the proceeds of any sale of the Pledged Collateral.

(b) The Grantor waives any right it may have to require the Administrative Agent to pursue any third person for any of the Secured Obligations. The Administrative Agent may comply with any applicable state or federal Law requirements in connection with a disposition of the Pledged Collateral and compliance will not be considered adversely to affect the commercial reasonableness of any sale of the Pledged Collateral. The Administrative Agent may sell the Pledged Collateral without giving any warranties as to the Pledged Collateral. The Administrative Agent may specifically disclaim any warranties of title or the like. This procedure will not be considered adversely to affect the commercial reasonableness of any sale of the Pledged Collateral. If the Administrative Agent sells any of the Pledged Collateral upon credit, the Grantor will be credited only with payments actually made by the purchaser, received by the Administrative Agent and applied to the indebtedness of the purchaser. In the event the purchaser fails to pay for the Pledged Collateral, the Administrative Agent may resell the Pledged Collateral and the Grantor shall be credited with the proceeds of the sale.

SECTION 12 Notices. All notices, requests or other communications hereunder shall be given in the manner and to the addresses specified in the Credit Agreement.

SECTION 13 No Waiver; Cumulative Remedies. No failure on the part of the Administrative Agent to exercise, and no delay in exercising, any right, remedy, power or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, remedy, power or privilege preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege. The rights and remedies under this Agreement or in any other Loan Document are cumulative and concurrent and not exclusive of any rights, remedies, powers and privileges that may otherwise be available to the Administrative Agent or any Lender.
