E. Section 9.11 of the Credit Agreement and Section 9(b) of the Pledge Agreement provide that additional Subsidiaries may become Subsidiary Pledgors under the Pledge Agreement by execution and delivery of an instrument in the form of this Supplement.

SECTION 1. In accordance with Section 9(b) of the Pledge Agreement, each Additional Pledgor by its signature hereby transfers, assigns and pledges to the Collateral Agent for the ratable benefit of the Secured Parties, and hereby grants to the Collateral Agent for the ratable benefit of the Secured Parties, a security interest in all of such Additional Pledgor’s right, title and interest in the following, whether now owned or existing or hereafter acquired or existing or arising (collectively, the “Additional Collateral”):

(b) the Additional Pledged Debt and the instruments evidencing the Additional Pledged Debt owed to such Additional Pledgor, and all interest, cash, instruments and other property or proceeds from time to time received, receivable or otherwise distributed in respect of or in exchange for any or all of such Additional Pledged Debt; and

(c) to the extent not covered by clauses (a) and (b) above, respectively, all Proceeds of any or all of the foregoing Additional Collateral.

For purposes of the Pledge Agreement, (x) the Collateral shall be deemed to include the Additional Collateral and (y) the After-acquired Pledged Shares shall be deemed to include the Additional After-acquired Pledge Shares.

SECTION 2. Red Man by its signature below becomes a Pledgor under the Pledge Agreement with the same force and effect as if originally named therein as a Pledgor and Red Man hereby agrees to all the terms and provisions of the Pledge Agreement applicable to it as a Pledgor thereunder. Each reference to a “Subsidiary Pledgor” or a “Pledgor” in the Pledge Agreement shall be deemed to include Red Man. The Pledge Agreement is hereby incorporated herein by reference.

SECTION 3. Each Additional Pledgor represents and warrants as follows:

(a) Schedule 1 hereto (i) correctly represents as of the date hereof (A) the issuer, the certificate number, the Pledgor and registered owner, the number and class and the percentage of the issued and outstanding Equity Interests of such class of all Additional Pledged Shares and (B) the issuer, the initial principal amount, the Pledgor and holder, date of and maturity date of all Additional Pledged Debt and (ii) together with Schedule 1 to the Pledge Agreement and the comparable schedules to each other Supplement to the Pledge Agreement, accurately and completely describes all Equity Interests, debt securities and promissory notes required to be pledged under the Pledge Agreement. Except as set forth on Schedule 1 hereto, the Additional Pledged Shares represent all (or 65% in the case of pledges of Foreign Subsidiaries) of the issued and outstanding Equity Interests of each class of Equity Interests of the issuer on the date hereof.

(b) Such Additional Pledgor is the legal and beneficial owner of the Additional Collateral pledged or assigned by such Additional Pledgor hereunder free and clear of any Lien, except for the Lien created by this Supplement to the Pledge Agreement.

(c) As of the date of this Supplement, the Additional Pledged Shares pledged by such Additional Pledgor hereunder have been duly authorized and validly issued and, in the case of Additional Pledged Shares issued by a corporation, are fully paid and non-assessable.

(d) The execution and delivery by such Additional Pledgor of this Supplement and the pledge of the Additional Collateral pledged by such Additional Pledgor hereunder pursuant hereto create a valid and perfected first priority security interest in the Additional Collateral, securing the payment of the Obligations, in favor of the Collateral Agent for the ratable benefit of the Secured Parties.

(e) Such Additional Pledgor has full power, authority and legal right to pledge all the Additional Collateral pledged by such Additional Pledgor pursuant to this Supplement and this Supplement constitutes a legal, valid and binding obligation of each Additional Pledgor, enforceable in accordance with its terms, except as enforceability thereof may be limited by bankruptcy, insolvency or other similar laws affecting creditors’ rights generally and subject to general principles of equity.

SECTION 4. This Supplement may be executed by one or more of the parties to this Supplement on any number of separate counterparts (including by facsimile or other electronic transmission), and all of said counterparts taken together shall be deemed to constitute one and the same instrument. A set of the copies of this Supplement signed by all the parties shall be lodged with the Collateral Agent and the Borrower. This Supplement shall become effective as to each Additional Pledgor when the Collateral Agent shall have received counterparts of this Supplement that, when taken together, bear the signatures of such Additional Pledgor and the Collateral Agent.

SECTION 5. Except as expressly supplemented hereby, the Pledge Agreement shall remain in full force and effect.

SECTION 6. THIS SUPPLEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

SECTION 7. Any provision of this Supplement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof and in the Pledge Agreement, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. The parties hereto shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.

SECTION 8. All notices, requests and demands pursuant hereto shall be made in accordance with Section 16 of the Pledge Agreement. All communications and notices hereunder to each Additional Pledgor shall be given to it in care of the Borrower at the Borrower’s address set forth in Section 14.2 of the Credit Agreement.
