Capitalized terms used herein and not defined herein shall have meanings assigned to such terms in the Indentures. Pursuant to the terms of the Indentures, NSM Cayman (the "Stock Pledgor") has agreed to pledge all of the issued and outstanding shares of capital stock in NSM (Del) to the Collateral Agent as security for all obligations of the Note Issuers under the Notes and the Indentures governing the Notes (the "Note Obligations") and all obligations of the Note Issuers under the Debentures and the Debenture Indenture (the "Debenture Obligations" and, together with the Note Obligations, the "Note/Debenture Obligations"). Accordingly, the Stock Pledgor, the Trustee and the Collateral Agent on behalf of the holders of the Notes and the Debentures, including any Depository therefor (and each of their respective successors or assigns) (such holders, the "Secured Parties"), hereby agree as follows: ARTICLE I Stock Pledge SECTION 1.1. Stock Pledge. As security for the payment and performance, as the case may be, in full of the Note/Debenture Obligations, the Stock Pledgor hereby transfers, grants, bargains, sells, conveys, hypothecates, pledges, sets over and delivers unto the Collateral Agent, its successors and assigns, and hereby grants to the Collateral Agent, its successors and assigns, for the benefit of the Secured Parties, a security interest in all of the Stock Pledgor's right, title and interest in, to and under (a) the shares of capital stock owned by it and listed on Schedule I hereto and any shares of capital stock of NSM(Del) obtained in the future by the Stock Pledgor and the certificates representing all such shares (the "Pledged Stock"); (b) all other property that may be delivered to and held by the Collateral Agent pursuant to the terms hereof in respect of the Pledged Stock; (c) subject to Section 1.5, all dividends, cash, instruments and other property from time to time received, receivable or otherwise distributed, in respect of, in exchange for or upon the conversion of the Pledged Stock; (d) subject to Section 1.5, all rights and privileges of the Stock Pledgor with respect to the Pledged Stock and other property referred to in clauses (a), (b) and (c) above; and (e) all proceeds of any of the foregoing (the items referred to in clauses (a) through (e) above being collectively referred to as the "Note/Debenture Collateral").

Each schedule so delivered shall supersede any prior schedules so delivered. TO HAVE AND TO HOLD the Note/Debenture Collateral, together with all right, title, interest, powers, privileges and preferences pertaining or incidental thereto, unto the Collateral Agent its successors and assigns, for the ratable benefit of the Secured Parties, forever; subject, however, to the terms, covenants and conditions hereinafter set forth and to the Indentures. -2- SECTION 1.2.

SECTION 1.4. Registration in Nominee Name; Denominations. The Collateral Agent, on behalf of the Secured Parties, shall have the right (in its sole and absolute discretion) to hold the Pledged Securities in its own name as pledgee, the name of its nominee (as pledgee or as sub-agent) or the name of the Stock Pledgor, endorsed or assigned in blank or in favor of the Collateral Agent. The Stock Pledgor will promptly give to the Collateral Agent copies of any notices or other communications received by it with respect to Pledged Securities registered in the name of the Stock Pledgor. The Collateral Agent shall at all times have the right to exchange the certificates representing Pledged Securities for certificates of smaller or larger denominations for any purpose consistent with this Agreement. SECTION 1.5. Voting Rights; Dividends and Interest, etc. (a) Unless and until an Event of Default under any of the Indentures shall have occurred and be continuing: (i) The Stock Pledgor shall be entitled to exercise any and all voting and/or other consensual rights and powers inuring to an owner of Pledged Securities or any part thereof for any purpose consistent with the terms of this Agreement and the Indentures; provided, however, that the Stock Pledgor will not be entitled to exercise any such right if the result thereof could materially and adversely affect the rights inuring to a holder of the Pledged Securities or the rights and remedies of any of the Secured Parties under this Agreement or the Indentures or the ability of the Secured Parties to exercise the same. (ii) The Collateral Agent shall execute and deliver to the Stock Pledgor, or cause to be executed and delivered to the Stock Pledgor, all such proxies, powers of attorney and other instruments as the Stock Pledgor may reasonably request for the purpose of enabling the Stock Pledgor to exercise the voting and/or consensual rights and powers it is entitled to exercise pursuant to subparagraph (i) above and to receive the cash dividends it is entitled to receive pursuant to subparagraph (iii) below. (iii) The Stock Pledgor shall be entitled to receive and retain any and all cash dividends paid on the Pledged Securities to the extent and only to the extent that such cash dividends are permitted by, and otherwise paid in accordance with, the terms and conditions of the Indentures and applicable laws. All noncash dividends and all dividends paid or payable in cash or otherwise in connection with a partial or total liquidation or dissolution, return of capital, capital surplus or paid- -4- in surplus, and all other distributions (other than distributions referred to in the preceding sentence) made on or in respect of the Pledged Securities, whether paid or payable in cash or otherwise, whether resulting from a subdivision, combination or reclassification of the outstanding capital stock of the issuer of any Pledged Securities or received in exchange for Pledged Securities or any part thereof, or as a result of any merger, consolidation, acquisition or other exchange of assets to which such issuer may be a party or otherwise, shall be and become part of the Note/Debenture Collateral, and, if received by any Stock Pledgor, shall not be commingled by such Stock Pledgor with any of its other funds or property but shall be held separate and apart therefrom, shall be held in trust for the benefit of the Collateral Agent and shall be forthwith delivered to the Collateral Agent in the same form as so received (with any necessary endorsement). (b) Upon the occurrence and during the continuance of an Event of Default, all rights of any Stock Pledgor to dividends that the Stock Pledgor is authorized to receive pursuant to paragraph (a)(iii) above shall cease, and all such rights shall thereupon become vested in the Collateral Agent, which shall have the sole and exclusive right and authority to receive and retain such dividends. All dividends received by the Stock Pledgor contrary to the provisions of this Section 5 shall be held in trust for the benefit of the Collateral Agent, shall be segregated from other property or funds of the Stock Pledgor and shall be forthwith delivered to the Collateral Agent in the same form as so received (with any necessary endorsement). Any and all money and other property paid over to or received by the Collateral Agent pursuant to the provisions of this paragraph (b) shall be retained by the Collateral Agent in an account to be established by the Collateral Agent upon receipt of such money or other property and shall be applied in accordance with the provisions of Section 1.7. After all Events of Default have been cured or waived, the Collateral Agent shall, within five Business Days after all such Events of Default have been cured or waived, repay to the Stock Pledgor all cash dividends (without interest), that the Stock Pledgor would otherwise be permitted to retain pursuant to the terms of paragraph (a)(iii) above and which remain in such account. (c) Upon the occurrence and during the continuance of an Event of Default, all rights of any Stock Pledgor to exercise the voting and consensual rights and powers it is entitled to exercise pursuant to paragraph (a)(i) of this Section 1.5, and the obligations of the Collateral Agent under paragraph (a)(ii) of this Section 1.5, shall cease, and all such rights shall thereupon become vested in the Collateral Agent, which shall have the sole and exclusive right and authority to exercise such voting and consensual rights and powers, provided that, unless otherwise directed by the holders of the Notes and the Debentures, the Collateral Agent shall have the right from time to time following and during the continuance of an Event of Default to permit the Stock Pledgor to exercise such rights. After all Events of Default have been cured or waived, the Stock Pledgor will have the right to exercise the voting and consensual rights and powers that it would otherwise be entitled to exercise pursuant to the terms of paragraph (a)(i) above. SECTION 1.6. Remedies upon Default. Upon the occurrence and during the continuance of an Event of Default subject to applicable regulatory and legal requirements, the Collateral Agent may sell the Note/Debenture Collateral, or any part thereof, at public or private sale or at any broker's board or on any securities exchange, for cash, upon credit or for future -5- delivery as the Collateral Agent shall deem appropriate. The Collateral Agent shall be authorized at any such sale (if it deems it advisable to do so) to restrict the prospective bidders or purchasers to persons who will represent and agree that they are purchasing the Note/Debenture Collateral for their own account for investment and not with a view to the distribution or sale thereof, and upon consummation of any such sale the Collateral Agent shall have the right to assign, transfer and deliver to the purchaser or purchasers thereof the Note/Debenture Collateral so sold. Each such purchaser at any such sale shall hold the property sold absolutely free from any claim or right on the part of any Stock Pledgor, and, to the extent permitted by applicable law, the Stock Pledgor hereby waives all rights of redemption, stay, valuation and appraisal that the Stock Pledgor now has or may at any time in the future have under any rule of law or statute now existing or hereafter enacted. The Collateral Agent shall give a Stock Pledgor 10 days' prior written notice (which the Stock Pledgor agrees is reasonable notice within the meaning of Section 9-504(3) of the Uniform Commercial Code as in effect in the State of New York or its equivalent in other jurisdictions) of the Collateral Agent's intention to make any sale of the Stock Pledgor's Note/Debenture Collateral. Such notice, in the case of a public sale, shall state the time and place for such sale and, in the case of a sale at a broker's board or on a securities exchange, shall state the board or exchange at which such sale is to be made and the day on which the Note/Debenture Collateral, or portion thereof, will first be offered for sale at such board or exchange. Any such public sale shall be held at such time or times within ordinary business hours and at such place or places as the Collateral Agent may fix and state in the notice of such sale. At any such sale, the Note/Debenture Collateral, or portion thereof, to be sold may be sold in one lot as an entirety or in separate parcels, as the Collateral Agent may (in its sole and absolute discretion) determine. The Collateral Agent shall not be obligated to make any sale of any Note/Debenture Collateral if it shall determine not to do so, regardless of the fact that notice of sale of such Note/Debenture Collateral shall have been given. The Collateral Agent may, without notice or publication, adjourn any public or private sale or cause the same to be adjourned from time to time by announcement at the time and place fixed for sale, and such sale may, without further notice, be made at the time and place to which the same was so adjourned. In case any sale of all or any part of the Note/Debenture Collateral is made on credit or for future delivery, the Note/Debenture Collateral so sold may be retained by the Collateral Agent until the sale price is paid in full by the purchaser or purchasers thereof but the Collateral Agent shall not incur any liability in case any such purchaser or purchasers shall fail to take up and pay for the Note/Debenture Collateral so sold and, in case of any such failure, such Note/Debenture Collateral may be sold again upon like notice. At any public (or, to the extent permitted by applicable law, private) sale made pursuant to this Section 1.6, any Secured Party may bid for or purchase, free from any right of redemption, stay or appraisal on the part of any Stock Pledgor (all said rights being also hereby waived and released), the Note/Debenture Collateral or any part thereof offered for sale and may make payment on account thereof by using any claim then due and payable to it from the Stock Pledgor as a credit against the purchase price, and it may, upon compliance with the terms of sale, hold, retain and dispose of such property without further accountability to such Pledgor therefor. For purposes hereof, (a) a written agreement to purchase the Note/Debenture Collateral or any portion thereof shall be treated as a sale thereof, (b) the Collateral Agent shall be free to carry out such sale pursuant to such agreement and (c) the Stock Pledgor shall not be entitled to the return -6- of the Note/Debenture Collateral or any portion thereof subject thereto, notwithstanding the fact that after the Collateral Agent shall have entered into such an agreement all Events of Default shall have been remedied and the Note/Debenture Obligations paid in full. As an alternative to exercising the power of sale herein conferred upon it, the Collateral Agent may proceed by a suit or suits at law or in equity to foreclose upon the Note/Debenture Collateral and to sell the Note/Debenture Collateral or any portion thereof pursuant to a judgment or decree of a court or courts having competent jurisdiction or pursuant to a proceeding by a court-appointed receiver. Any sale pursuant to the provisions of this Section 1.6 shall be deemed to conform to the commercially reasonable standards as provided in Section 9-504(3) of the Uniform Commercial Code as in effect in the State of New York or its equivalent in other jurisdictions. SECTION 1.7. Reimbursement of Collateral Agent. (a) The Stock Pledgor agrees to pay upon demand to the Collateral Agent the amount of any and all reasonable expenses, including the reasonable fees, other charges and disbursements of its counsel and of any experts or agents, that the Collateral Agent may incur in connection with (i) the administration of this Agreement, (ii) the custody or preservation of, or the sale of, collection from, or other realization upon, any of the Note/Debenture Collateral, (iii) the exercise or enforcement of any of the rights of the Collateral Agent hereunder or (iv) the failure by the Stock Pledgor to perform or observe any of the provisions hereof. (b) The Stock Pledgor agrees to indemnify the Collateral Agent against, and hold the Collateral Agent harmless from, any and all losses, claims, damages, liabilities and related expenses, including reasonable counsel fees, other charges and disbursements, incurred by or asserted against the Collateral Agent arising out of, in any way connected with, or as a result of (i) the execution or delivery of this Agreement or any agreement or instrument contemplated hereby, the performance by the parties hereto of their respective obligations hereunder or the consummation of the Transactions (as defined in the Purchase Agreement) and the other transactions contemplated hereby or (ii) any claim, litigation, investigation or proceeding relating to any of the foregoing, whether or not the Collateral Agent is a party thereto, provided that such indemnity shall not, as to the Collateral Agent, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Collateral Agent. (c) Any amounts payable as provided hereunder shall be additional Note/Debenture Obligations secured hereby and by the Indentures. The provisions of this Section 1.7 shall remain operative and in full force and effect regardless of the termination of this Agreement, the consummation of the transactions contemplated hereby, the repayment of any of the Note/Debenture Obligations, the invalidity or unenforceability of any term or provision of this Agreement or any investigation made by or on behalf of the Collateral Agent or any other Secured Party. All amounts due under this Section 1.7 shall be payable on written demand therefor and shall bear interest at the rate specified therefor in the Notes and the Debentures, as relevant. SECTION 1.8. Collateral Agent Appointed Attorney-in-Fact. The Stock Pledgor hereby appoints the Collateral Agent the attorney-in-fact of the Stock Pledgor for the purpose of carrying out the provisions of this Agreement and taking any action and executing any instrument -7- that the Collateral Agent may deem necessary or advisable to accomplish the purposes hereof, which appointment is irrevocable and coupled with an interest. Without limiting the generality of the foregoing, the Collateral Agent shall have the right, upon the occurrence and during the continuance of an Event of Default, with full power of substitution either in the Collateral Agent's name or in the name of the Stock Pledgor, to ask for, demand, sue for, collect, receive and give acquittance for any and all moneys due or to become due under and by virtue of any Note/Debenture Collateral, to endorse checks, drafts, orders and other instruments for the payment of money payable to the Stock Pledgor representing any interest or dividend or other distribution payable in respect of the Note/Debenture Collateral or any part thereof or on account thereof and to give full discharge for the same, to settle, compromise, prosecute or defend any action, claim or proceeding with respect thereto, and to sell, assign, endorse, pledge, transfer and to make any agreement respecting, or otherwise deal with, the same; provided, however, that nothing herein contained shall be construed as requiring or obligating the Collateral Agent to make any commitment or to make any inquiry as to the nature or sufficiency of any payment received by the Collateral Agent, or to present or file any claim or notice, or to take any action with respect to the Note/Debenture Collateral or any part thereof or the moneys due or to become due in respect thereof or any property covered thereby. The Collateral Agent and the other Secured Parties shall be accountable only for amounts actually received as a result of the exercise of the powers granted to them herein, and neither they nor their officers, directors, employees or agents shall be responsible to the Stock Pledgor for any act or failure to act hereunder, except for their own gross negligence or willful misconduct. SECTION 1.9. Waivers; Amendment. (a) No failure or delay of the Collateral Agent in exercising any power or right hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Collateral Agent hereunder are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provisions of this Agreement or consent to any departure by the Stock Pledgor therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) below, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice or demand on the Stock Pledgor in any case shall entitle the Stock Pledgor to any other or further notice or demand in similar or other circumstances. (b) Neither this Agreement nor any provision hereof may be waived, amended or modified unless the conditions specified in Sections 9.01 and 9.02 of the Indentures have been satisfied and a written agreement is entered into between the Collateral Agent and the Stock Pledgor with respect to which such waiver, amendment or modification is to apply. SECTION 1.10. Securities Act, etc. In view of the position of the Stock Pledgor in relation to the Pledged Securities, or because of other current or future circumstances, a question may arise under the Securities Act of 1933, as now or hereafter in effect, or any similar statute hereafter enacted analogous in purpose or effect (such Act and any such similar statute as from time to time in effect being called the "Federal Securities Laws") with respect to any disposition of the Pledged Securities permitted hereunder. The Stock Pledgor understands that compliance with the Federal Securities Laws might very strictly limit the course of conduct of the -8- Collateral Agent if the Collateral Agent were to attempt to dispose of all or any part of the Pledged Securities, and might also limit the extent to which or the manner in which any subsequent transferee of any Pledged Securities could dispose of the same. Similarly, there may be other legal restrictions or limitations affecting the Collateral Agent in any attempt to dispose of all or part of the Pledged Securities under applicable Blue Sky or other state securities laws or similar laws analogous in purpose or effect. The Stock Pledgor recognizes that in light of such restrictions and limitations the Collateral Agent may, with respect to any sale of the Pledged Securities, limit the purchasers to those who will agree, among other things, to acquire such Pledged Securities for their own account, for investment, and not with a view to the distribution or resale thereof. The Stock Pledgor acknowledges and agrees that in light of such restrictions and limitations, the Collateral Agent, in its sole and absolute discretion, (a) may proceed to make such a sale whether or not a registration statement for the purpose of registering such Pledged Securities or part thereof shall have been filed under the Federal Securities Laws and (b) may approach and negotiate with a single potential purchaser to effect such sale. The Stock Pledgor acknowledges and agrees that any such sale might result in prices and other terms less favorable to the seller than if such sale were a public sale without such restrictions. In the event of any such sale, the Collateral Agent shall incur no responsibility or liability for selling all or any part of the Pledged Securities at a price that the Collateral Agent, in its sole and absolute discretion, may in good faith deem reasonable under the circumstances, notwithstanding the possibility that a substantially higher price might have been realized if the sale were deferred until after registration as aforesaid or if more than a single purchaser were approached. The provisions of this Section 1.10 will apply notwithstanding the existence of a public or private market upon which the quotations or sales prices may exceed substantially the price at which the Collateral Agent sells. SECTION 1.11. Registration, etc. The Stock Pledgor agrees that, upon the occurrence and during the continuance of an Event of Default hereunder, if for any reason the Collateral Agent desires to sell any of the Pledged Securities at a public sale, it will, at any time and from time to time, upon the written request of the Collateral Agent, use its best efforts to take or to cause the issuer of such Pledged Securities to take such action and prepare, distribute and/or file such documents, as are required or advisable in the reasonable opinion of counsel for the Collateral Agent to permit the public sale of such Pledged Securities. The Stock Pledgor further agrees to indemnify, defend and hold harmless the Collateral Agent, each other Secured Party, any underwriter and their respective officers, directors, affiliates and controlling persons from and against all loss, liability, expenses, costs of counsel (including, without limitation, reasonable fees and expenses to the Collateral Agent of legal counsel), and claims (including the costs of investigation) that they may incur insofar as such loss, liability, expense or claim arises out of or is based upon any alleged untrue statement of a material fact contained in any prospectus (or any amendment or supplement thereto) or in any notification or offering circular, or arises out of or is based upon any alleged omission to state a material fact required to be stated therein or necessary to make the statements in any thereof not misleading, except insofar as the same may have been caused by any untrue statement or omission based upon information furnished in writing to the Stock Pledgor or the issuer of such Pledged Securities by the Collateral Agent or any other Secured Party expressly for use therein. The Stock Pledgor further agrees, upon such written request referred to above, to use its best efforts to qualify, file or register, or cause the issuer of such Pledged Securities to qualify, file or register, any of the Pledged Securities under the Blue -9- Sky or other securities laws of such states as may be requested by the Collateral Agent and keep effective, or cause to be kept effective, all such qualifications, filings or registrations. The Stock Pledgor will bear all costs and expenses of carrying out its obligations under this Section 1. 1 1. The Stock Pledgor acknowledges that there is no adequate remedy at law for failure by it to comply with the provisions of this Section 1.11 and that such failure would not be adequately compensable in damages, and therefore agrees that its agreements contained in this Section 1. 1 1 may be specifically enforced. SECTION 1.12. Security Interest Absolute. All rights of the Collateral Agent hereunder, the grant of a security interest in the Note/Debenture Collateral and all obligations of the Stock Pledgor hereunder, shall be absolute and unconditional irrespective of (a) any lack of validity or enforceability of the Indentures, the Notes or the Debentures with respect to any of the Note/Debenture Obligations or any other agreement or instrument relating to any of the foregoing, (b) any change in the time, manner or place of payment of, or in any other term of, all or any of the Note/Debenture Obligations, or any other amendment or waiver of or any consent to any departure from the Indentures, the Notes or the Debentures relating to any of the foregoing, (c) any exchange, release or nonperfection of any other collateral, or any release or amendment or waiver of or consent to or departure from any guaranty, for all or any of the Note/Debentures Obligations or (d) any other circumstance that might otherwise constitute a defense available to, or a discharge of, the Stock Pledgor in respect of the Note/Debenture Obligations or in respect of this Agreement (other than the indefeasible payment in full of all the Note/Debenture Obligations). SECTION 1.13. Termination or Release. (a) This Agreement (except for Section 1.7) and the security interests granted hereby shall terminate when all the Note/Debenture Obligations have been indefeasibly paid in full. (b) In connection with any termination pursuant to paragraph (a), the Collateral Agent shall execute and deliver to the Stock Pledgor, at the Stock Pledgor's expense, all documents that the Stock Pledgor shall reasonably request to evidence such termination. Any execution and delivery of documents pursuant to this Section 1. 14 shall be without recourse to or warranty by the Collateral Agent. ARTICLE II Priority of Rights SECTION 2.1. Second Priority Creditors. Each holder of any Debenture agrees that (i) the interests of the holders of Senior Notes and the holders of Senior Subordinated Notes, including their interests in any payments to be made from the proceeds of any sale or other perfection or creation of any security interests or liens in the Note/Debenture Collateral on behalf of any Secured Party shall be prior to the interests of the holders of the Debentures in the Note/Debenture Collateral, including their interests in any such payments, to the extent and in the manner provided in Section 2.3, (and from time to time shall execute and deliver any instruments or agreements as may be reasonably necessary or desirable to confirm the same) and (ii) at all times that a Default under the Senior Notes or Senior Note Indenture or Senior Subordinated -10- Notes or Senior Subordinated Note Indenture has occurred and is continuing, absent the consent of the holders of a majority of the aggregate principal amount of each of the Senior Notes outstanding and the Senior Subordinated Notes outstanding, the holders of the Debentures shall refrain from taking any action to foreclose upon, acquire title to (by bidding in at foreclosure or otherwise), take possession of, liquidate or otherwise proceed against any of the Note/Debenture Collateral. SECTION 2.2. Senior Subordinated Noteholders.
