SECTION 3. REPRESENTATIONS AND WARRANTIES

To induce the Trustee, on behalf of the Noteholders, to enter into the Indenture and the Noteholders to purchase the Notes, each Grantor hereby represents and warrants to the Secured Parties, that:

3.1 Title; No Other Liens. Such Grantor owns each item of the Collateral purported to be owned by it free and clear of any and all Liens or claims, including, without limitation, Liens arising as a result of such Grantor becoming bound (as a result of merger or otherwise) as Grantor under a security agreement entered into by another Person, in each case except for Permitted Liens. No effective financing statement, mortgage or other instrument similar in effect with respect to all or any part of the Collateral is on file or of record in any public office, except such as have been filed in favor of the Collateral Agent pursuant to this Agreement or with respect to Permitted Liens.

3.2 Perfected First Priority Liens.

(a) The security interests granted pursuant to this Agreement (i) constitute valid and, subject only to (x) with respect to any Collateral that solely can be perfected by filing, to the extent Article 9 of the UCC applies thereto, the filing of financing statements in the filing offices identified on Schedule 2 hereto and (y) with respect to any Collateral that can be perfected by possession, the Collateral Agent receiving possession thereto, fully perfected security interests in all of the Collateral, in favor of the Collateral Agent, as collateral security for the Secured Obligations, enforceable in accordance with the terms hereof against all creditors of such Grantor, (ii) are subject to no other Liens on the Collateral, except for Permitted Liens, and (iii) are prior to all other Liens on the Collateral, except for (x) the Permitted Liens described in clauses (3), (11) and (12) of the definition of “Permitted Liens” set forth in the Indenture, with respect to the Collateral described in clause (i)(x) above and (y) for the Permitted Liens described in clauses (3), (11) and (12) (and, to the extent required by law, clauses (8) and (9)) of the definition of “Permitted Liens” set forth in the Indenture, with respect to the Collateral described in clause (i)(y) above. Without limiting the foregoing, each Grantor has taken all actions necessary, including, without limitation, those specified in Section 4.1 (but subject in all cases to Section 2.3), to: (A) establish the Collateral Agent’s “control” (within the meanings of Sections 8-106 and 9-106 of the UCC) over any portion of the Investment Property constituting Certificated Securities, Uncertificated Securities, Securities Accounts, Securities Entitlements or Commodity Accounts (each as defined in the UCC) and (B) establish the Collateral Agent’s “control” (within the meaning of Section 9-104 of the UCC) over all Deposit Accounts.

(b) No authorization, approval or other action by, and no notice to or filing with, any Governmental Authority or regulatory body (except those which have been made or obtained) is required for either (i) the pledge or grant by any Grantor of the security interests purported to be created in favor of the Collateral Agent hereunder or (ii) the exercise by the Collateral Agent of any rights or remedies in respect of any Collateral (whether specifically granted or created hereunder or created or provided for by applicable law), except (A) filings and actions specified on Schedule 2 and (B) as may be required, in connection with the disposition of any Investment Property, by laws generally affecting the offering and sale of securities.

(c) All obligations, indebtedness and liabilities of each Grantor to Banc One pursuant to the Banc One Purchase Agreements have been terminated and satisfied in full, and the Banc One Purchase Agreements are of no further force and effect.

Each Grantor is organized solely under the law of the jurisdiction so specified and has not filed any certificates of domestication, transfer or continuance in any other jurisdiction. Except as otherwise indicated on Schedule 3, the jurisdiction of each such Grantor’s organization or formation is required to maintain a public record showing the Grantor to have been organized or formed. Except as specified on Schedule 3, such Grantor has not changed its name, jurisdiction of organization or formation, chief executive office or sole place of business or its corporate structure in any way (e.g. by merger, consolidation, change in corporate form or otherwise) within the previous five (5) year

period ending on the date hereof, solely in the case of each Grantor and has not within such period become bound (whether as a result of merger or otherwise) as grantor under a security agreement entered into by another Person, which has not heretofore been terminated.

3.4 Inventory, Equipment and Books and Records. The Inventory and the Equipment (other than mobile goods) and the books and records pertaining to the Collateral are kept at the locations listed on Schedule 4. No material Inventory or Equipment (in the aggregate) of such Grantor is in the possession of an issuer of a negotiable document (as determined in accordance with Section 7-104 of the UCC) therefor that has not been delivered to the Collateral Agent or is otherwise in the possession of any bailee or warehouseman.

3.5 Farm Products. None of the Collateral constitutes, or is the Proceeds of, Farm Products.

(a) The shares of Pledged Stock pledged by such Grantor hereunder constitute all of the issued and outstanding shares of all classes of the Capital Stock of each Issuer owned by such Grantor.

(b) All the shares of the Pledged Stock of such Grantor have been duly and validly issued and are fully paid and nonassessable.

(c) Each limited liability company or member’s interest or partnership interest owned by such Grantor and included in the Pledged Stock is certificated (and each Grantor covenants that it will not issue or cause or permit its Subsidiaries to issue any Capital Stock in uncertificated form or seek to convert all or any part of its existing Capital Stock into uncertificated form) and the terms of such certificated limited liability company or member’s interests and partnership interests expressly provide that they are securities governed by Article 8 of the Uniform Commercial Code in effect from time to time in the applicable jurisdiction.

(d) Such Grantor is the record and beneficial owner of, and has good and marketable title to, the Investment Property pledged by it hereunder, free of any and all Liens or options in favor of, or claims of, any other Person, except Permitted Liens.

(e) Each Issuer that is not a Grantor but is an Affiliate of any Grantor has executed and delivered to the Collateral Agent an Acknowledgment and Agreement, in substantially the form of Exhibit A, to the pledge of the Pledged Securities pursuant to this Agreement.

3.7 Receivables.

No amount payable to such Grantor under or in connection with any Receivable is evidenced by any Instrument or Chattel Paper which has not been delivered to the Collateral Agent (other than Receivables evidenced by Instruments in an aggregate amount less than $25,000 per Grantor (collectively, the “Non-Deliverable Collateral”)).

(b) Upon the filing of a financing statement covering any Commercial Tort Claim referred to in Section 4.8 hereof against such Grantor in the jurisdiction specified in Schedule 2 hereto, the security interest granted in such Commercial Tort Claim will constitute a valid perfected security interest in favor of the Collateral Agent, for the benefit of the Secured Parties, as collateral security for such Grantor’s Obligations, enforceable in accordance with the terms hereof against all creditors of such Grantor and any Persons purporting to purchase such Collateral except for unrecorded liens permitted herein which have priority over the Liens on such Collateral by operation of law.

SECTION 4. COVENANTS

Each Grantor covenants and agrees with the Secured Parties that, from and after the date of this Agreement until the Secured Obligations (other than unmatured contingent reimbursement and indemnification Obligations) shall have been Discharged:

4.1 Delivery and Control of Instruments, Chattel Paper, Investment Property and Deposit Accounts.

(a) If any of the Collateral (other than the Non-Deliverable Collateral) shall be or become evidenced or represented by any Instrument, Certificated Security or Chattel Paper, such Grantor shall cause such Instrument, Certificated Security or Chattel Paper to be promptly delivered to the Collateral Agent and duly endorsed in a manner satisfactory to the Collateral Agent, to be held as Collateral pursuant to this Agreement.

(b) If any of the Collateral shall be or become evidenced or represented by an Uncertificated Security, such Grantor shall cause, or with respect to any Issuer that is not an Affiliate of any Grantor, use commercially reasonable efforts to cause, such Issuer thereof either (i) to register the Collateral Agent as the registered owner of such Uncertificated Security, upon original issue or registration of transfer, or (ii) to agree in writing with such Grantor and the Collateral Agent that such Issuer will comply with instructions with respect to such Uncertificated Security originated by the Collateral Agent without further consent of such Grantor, such agreement to be in substantially the form of Exhibit C.

(a) Upon request of the Collateral Agent, such Grantor shall execute and deliver, and have recorded, any and all agreements, instruments, documents, and papers as the Collateral Agent may request to evidence the Collateral Agent’s security interest, on behalf of the Secured Parties, in any Copyright, Patent, Trademark or other Intellectual Property included in the Collateral and the goodwill and general intangibles of such Grantor relating thereto or represented thereby.

(b) Such Grantor agrees that, should it obtain an ownership interest in any item of Intellectual Property which is not now a part of the Collateral (the “After-Acquired Intellectual Property”), (i) the provisions of Section 2 shall automatically apply thereto, (ii) any such After-Acquired Intellectual Property, and in the case of trademarks, the goodwill of the business connected therewith or symbolized thereby, shall automatically become part of the Collateral, (iii) it shall give prompt written notice thereof to the Collateral Agent in accordance herewith, and (iv) it shall provide the Collateral Agent promptly (and, in any event within five (5) Business Days after the last day of the fiscal quarter in which such Grantor acquires such ownership interest in any Intellectual Property) with an amended Schedule 5 and take the actions specified in Section 4.5(d).

(c) Such Grantor agrees to execute an Intellectual Property Security Agreement with respect to its Intellectual Property in substantially the form of Exhibit B-1 in

SECTION 5. REMEDIAL PROVISIONS

5.1 Certain Matters Relating to Receivables.

(a) The Collateral Agent hereby authorizes each Grantor to collect such Grantor’s Receivables; provided, that the Collateral Agent may curtail or terminate said authority at any time after the occurrence and during the continuance of an Event of Default. If required by the Collateral Agent at any time after the occurrence and during the continuance of an Event of Default, any payments of Receivables, when collected by any Grantor, (i) shall be forthwith (and, in any event, within two (2) Business Days) deposited by such Grantor in the exact form received, duly endorsed by such Grantor to the Collateral Agent if required, in a Collateral Account maintained under the control of the Collateral Agent, subject to withdrawal by the Collateral Agent for the account of the Secured Parties only as provided in Section 5, and (ii) until so turned over, shall be held by such Grantor in trust for the Secured Parties, segregated from other funds of such Grantor. Each such deposit of Proceeds of Receivables shall be accompanied by a report identifying in reasonable detail the nature and source of the payments included in the deposit.

(b) At the Collateral Agent’s request, after the occurrence and during the continuance of an Event of Default, each Grantor shall deliver to the Collateral Agent all original and other documents evidencing, and relating to, the agreements and transactions which gave rise to the Receivables (other than Non-Deliverable Collateral), including, without limitation, all original orders, invoices and shipping receipts.

5.2 Communications with Obligors; Grantors Remain Liable.

(a) The Collateral Agent in its own name or in the name of others may at any time after the occurrence and during the continuance of an Event of Default (but not otherwise) communicate with obligors under the Receivables to verify with them, to the Collateral Agent’s satisfaction, the existence, amount and terms of any Receivables.

(b) Upon the request of the Collateral Agent at any time after the occurrence and during the continuance of an Event of Default (but not otherwise), each Grantor shall notify obligors under the Receivables that the Receivables have been assigned to the Collateral Agent for the ratable benefit of the Secured Parties and that payments in respect thereof shall be made directly to the Collateral Agent or as the Collateral Agent shall direct.

(c) Anything herein to the contrary notwithstanding, each Grantor shall remain liable under each of the Receivables to observe and perform all the conditions and obligations to be observed and performed by it thereunder, all in accordance with the terms of any agreement giving rise thereto. No Secured Party shall have any obligation or liability under any Receivable (or any agreement giving rise thereto) by reason of or arising out of this Agreement or the receipt by any Secured Party of any payment relating thereto, nor shall any Secured Party be obligated in any manner to perform any of the obligations of any Grantor under

or pursuant to any Receivable (or any agreement giving rise thereto), to make any payment, to make any inquiry as to the nature or the sufficiency of any payment received by it or as to the sufficiency of any performance by any party thereunder, to present or file any claim, to take any action to enforce any performance or to collect the payment of any amounts which may have been assigned to it or to which it may be entitled at any time or times.

5.3 Pledged Securities.

(a) Unless an Event of Default shall have occurred and be continuing and the Collateral Agent shall have given notice to the relevant Grantor of the Collateral Agent’s intent to exercise its corresponding rights pursuant to Section 5.3(b), each Grantor shall be permitted to receive all cash dividends made in respect of the Pledged Stock and all payments made in respect of the Pledged Notes, in each case to the extent permitted in the Indenture, and to exercise all voting and corporate or other ownership rights with respect to the Pledged Securities; provided, however, that no vote shall be cast, and no corporate or other ownership right shall be exercised or other action taken which would impair the Collateral or which would be inconsistent with or result in any violation of any provision of the Indenture, this Agreement or any other Note Document.

(b) If an Event of Default shall occur and be continuing and the Collateral Agent shall give notice of its intent to exercise such rights to the relevant Grantor, (i) the Collateral Agent shall have the right to receive any and all dividends, payments or other Proceeds made in respect of the Pledged Securities and make application thereof to the Obligations in the order set forth in Section 5.5, and (ii) any or all of the Pledged Securities shall be registered in the name of the Collateral Agent or its nominee, and the Collateral Agent or its nominee may thereafter exercise (x) all voting, corporate or other ownership and other rights pertaining to such Pledged Securities at any meeting of shareholders or other equity holders of the relevant Issuer or Issuers or otherwise and (y) any and all rights of conversion, exchange and subscription and any other rights, privileges or options pertaining to such Pledged Securities as if it were the absolute owner thereof (including, without limitation, the right to exchange at its discretion any and all of the Pledged Securities upon the merger, consolidation, reorganization, recapitalization or other fundamental change in the corporate or other structure of any Issuer, or upon the exercise by any Grantor or the Collateral Agent of any right, privilege or option pertaining to such Pledged Securities, and in connection therewith, the right to deposit and deliver any and all of the Pledged Securities with any committee, depositary, transfer agent, registrar or other designated agency upon such terms and conditions as the Collateral Agent may determine), all without liability except to account for property actually received by it, but the Collateral Agent shall have no duty to any Grantor to exercise any such right, privilege or option and shall not be responsible for any failure to do so or delay in so doing.

(c) Each Grantor hereby authorizes and instructs each Issuer of any Pledged Securities pledged by such Grantor hereunder (i) to comply with any instruction received by it from the Collateral Agent in writing that (x) states that an Event of Default has occurred and is continuing and (y) is otherwise in accordance with the terms of this Agreement, without any other or further instructions from such Grantor, and each Grantor agrees that each Issuer shall be fully protected in so complying, and (ii) unless otherwise expressly permitted hereby, to pay any

dividends or other payments with respect to the Pledged Securities directly to the Collateral Agent.

5.4 Proceeds to be Turned Over To Collateral Agent. In addition to the other rights of the Secured Parties under this Section 5, with respect to payments of Receivables, if an Event of Default shall occur and be continuing, all Proceeds received by any Grantor consisting of cash, cash equivalents, checks and other near-cash items shall be held by such Grantor in trust for the Secured Parties, segregated from other funds of such Grantor, and shall forthwith upon receipt by such Grantor, be turned over to the Collateral Agent in the exact form received by such Grantor (duly endorsed by such Grantor to the Collateral Agent, if required). All Proceeds received by the Collateral Agent hereunder shall be held by the Collateral Agent in a Collateral Account maintained under its control. All Proceeds while held by the Collateral Agent in a Collateral Account (or by such Grantor in trust for the Secured Parties) shall continue to be held as collateral security for all the Obligations and shall not constitute payment thereof until applied as provided in Section 5.5.

5.5 Application of Proceeds. Subject to the Intercreditor Agreement, if an Event of Default shall have occurred and be continuing, the Collateral Agent shall at the direction of the Trustee or Noteholders owning at least a majority in aggregate principal amount of the Notes (including Additional Notes, if any), exercise any remedies granted to the Trustee under Article 7 of the Indenture and apply all or any part of Proceeds constituting Collateral realized through the exercise by the Collateral Agent of its remedies hereunder, whether or not held in any Collateral Account, in payment of the Secured Obligations in the order set forth in Section 7.10 of the Indenture.

5.6 Code and Other Remedies.

(a) If an Event of Default shall occur and be continuing, the Collateral Agent, on behalf of the Secured Parties, may exercise (subject to obtaining any required approvals from any Governmental Authorities), in addition to all other rights and remedies granted to them in this Agreement and in any other instrument or agreement securing, evidencing or relating to the Secured Obligations, all rights and remedies of a secured party under the UCC (whether or not the UCC applies to the affected Collateral) or any other applicable law or in equity. Without limiting the generality of the foregoing, the Collateral Agent, without demand of performance or other demand, presentment, protest, advertisement or notice of any kind (except any notice required by law referred to below) to or upon any Grantor or any other Person (all and each of which demands, defenses, advertisements and notices are hereby waived), may in such circumstances forthwith collect, receive, appropriate and realize upon the Collateral, or any part thereof, and/or may forthwith sell, lease, license, assign, give option or options to purchase, or otherwise dispose of and deliver the Collateral or any part thereof (or contract to do any of the foregoing), in one or more parcels at public or private sale or sales, at any exchange, broker’s board or office of any Secured Party or elsewhere upon such terms and conditions as it may deem advisable and at such prices as it may deem best, for cash or on credit or for future delivery without assumption of any credit risk. Each Secured Party shall have the right upon any such public sale or sales, and, to the extent permitted by law, upon any such private sale or sales, to purchase the whole or any part of the Collateral so sold, free of any right or equity of redemption in any Grantor, which right or equity is hereby waived and released to the fullest extent

permitted by applicable law. Each purchaser at any such sale shall hold the property sold absolutely free from any claim or right on the part of any Grantor, and each Grantor hereby waives (to the extent permitted by applicable law) all rights of redemption, stay and/or appraisal which it now has or may at any time in the future have under any rule of law or statute now existing or hereafter enacted. Each Grantor agrees that, to the extent notice of sale shall be required by law, at least ten (10) days notice to such Grantor of the time and place of any public sale or the time after which any private sale is to be made shall constitute reasonable notification. The Collateral Agent shall not be obligated to make any sale of the Collateral or any part thereof regardless of notice of sale having been given. The Collateral Agent may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned. The Collateral Agent may sell the Collateral without giving any warranties as to the Collateral. The Collateral Agent may specifically disclaim or modify any warranties of title or the like. This procedure will not be considered to adversely effect the commercial reasonableness of any sale of the Collateral or any part thereof. Each Grantor agrees that it would not be commercially unreasonable for the Collateral Agent to dispose of the Collateral or any portion thereof by using Internet sites that provide for the auction of assets of the types included in the Collateral or that have the reasonable capability of doing so, or that match buyers and sellers of assets. Each Grantor hereby waives any claims against the Collateral Agent or Trustee arising by reason of the fact that the price at which any Collateral may have been sold at such a private sale was less than the price which might have been obtained at a public sale, even if the Collateral Agent accepts the first offer received and does not offer such Collateral to more than one offeree. Each Grantor further agrees, at the Collateral Agent’s request, to assemble the Collateral or any part thereof and make it available to the Collateral Agent at places which the Collateral Agent shall reasonably select, whether at such Grantor’s premises or elsewhere. The Collateral Agent shall apply the net proceeds of any action taken by it pursuant to this Section 5.6, after deducting all reasonable costs and expenses of every kind incurred in connection therewith or incidental to the care or safekeeping of any of the Collateral or in any way relating to the Collateral or the rights of the Secured Parties hereunder, including, without limitation, reasonable attorneys’ fees and disbursements, to the payment in whole or in part of the Secured Obligations, in accordance with Section 7.10 of the Indenture, and only after such application and after the payment by the Collateral Agent of any other amount required by any provision of law, including, without limitation, Section 9-615(a) of the UCC, need the Collateral Agent account for the surplus, if any, to any Grantor. To the extent permitted by applicable law, each Grantor waives all claims, damages and demands it may acquire against any Secured Party arising out of the exercise by them of any rights hereunder.

(b) In the event of any disposition of any of the Intellectual Property, the goodwill of the business connected with and symbolized by any Trademarks subject to such disposition shall be included, and the applicable Grantor shall supply the Collateral Agent or its designee with such Grantor’s know-how and expertise, and with documents and things embodying the same, relating to the manufacture, distribution, advertising and sale of products or the provision of services relating to any Intellectual Property subject to such disposition, and such Grantor’s customer lists and other records and documents relating to such Intellectual Property and to the manufacture, distribution, advertising and sale of such products and services.

5.7 Registration Rights.

(a) If the Collateral Agent shall determine to exercise its right to sell any or all of the Pledged Stock pursuant to Section 5.6, and if in the opinion of the Collateral Agent it is necessary or advisable to have the Pledged Stock, or that portion thereof to be sold, registered under the provisions of the Securities Act, the relevant Grantor will cause, or with respect to any Issuer that is not an Affiliate of any Grantor, use commercially reasonable efforts to cause, the Issuer thereof to (i) execute and deliver, and cause the directors and officers of such Issuer to execute and deliver, all such instruments and documents, and do or cause to be done all such other acts as may be, in the opinion of the Collateral Agent, necessary or advisable to register the Pledged Stock, or that portion thereof to be sold, under the provisions of the Securities Act, (ii) use its best efforts to cause the registration statement relating thereto to become effective and to remain effective for a period of one (1) year from the date of the first public offering of the Pledged Stock, or that portion thereof to be sold, and (iii) make all amendments thereto and/or to the related prospectus which, in the opinion of the Collateral Agent, are necessary or advisable, all in conformity with the requirements of the Securities Act and the rules and regulations of the SEC applicable thereto. The relevant Grantor agrees to cause, or with respect to any Issuer that is not an Affiliate of any Grantor, use commercially reasonable efforts to cause, such Issuer to comply with the provisions of the securities or “Blue Sky” laws of any and all jurisdictions which the Collateral Agent shall designate and to make available to its security holders, as soon as practicable, an earnings statement (which need not be audited) which will satisfy the provisions of Section 11(a) of the Securities Act.

(b) Each Grantor recognizes that the Collateral Agent may be unable to effect a public sale of any or all of the Pledged Stock or the Pledged Debt Securities, by reason of certain prohibitions contained in the Securities Act and applicable state securities laws or otherwise, and may be compelled to resort to one or more private sales thereof to a restricted group of purchasers which will be obliged to agree, among other things, to acquire such securities for their own account for investment and not with a view to the distribution or resale thereof. Each Grantor acknowledges and agrees that any such private sale may result in prices and other terms less favorable than if such sale were a public sale and, notwithstanding such circumstances, agrees that any such private sale shall be deemed to have been made in a commercially reasonable manner. The Collateral Agent shall be under no obligation to delay a sale of any of the Pledged Stock or the Pledged Debt Securities for the period of time necessary to permit the Issuer thereof to register such securities for public sale under the Securities Act, or under applicable state securities laws, even if such Issuer would agree to do so.

(c) Each Grantor agrees to use its best efforts to do or cause to be done all such other acts as may be necessary to make such sale or sales of all or any portion of the Pledged Stock pursuant to this Section 5.7 valid and binding and in compliance with any and all other applicable Legal Requirements. Each Grantor further agrees that a breach of any of the covenants contained in this Section 5.7 will cause irreparable injury to the Secured Parties, that the Secured Parties have no adequate remedy at law in respect of such breach and, as a consequence, that each and every covenant contained in this Section 5.7 shall be specifically enforceable against such Grantor, and such Grantor hereby waives and agrees not to assert any defenses against an action for specific performance of such covenants except for a defense that no Event of Default has occurred and is continuing or a defense of payment.

5.8 Waiver; Deficiency. Each Grantor shall remain liable for any deficiency if the proceeds of any sale or other disposition of the Collateral or any part thereof are insufficient to pay the Secured Obligations and the fees and disbursements of any attorneys employed by any Secured Party to collect such deficiency.

5.9 Exercise of Control. Unless an Event of Default shall have occurred and be continuing, the Collateral Agent agrees that it will not (nor will it direct any agent acting as a trustee or other agent as secured party pursuant to the Intercreditor Agreement or any Control Agreement to) deliver any notice of control or otherwise exercise control or issue any entitlement orders or instructions over any Account or any other deposit or securities account of such Grantor subject to a Control Agreement. Upon the cure or written waiver of such Event of Default, the Collateral Agent will (or will direct any agent acting as a trustee or other agent as secured party pursuant to the Intercreditor Agreement or any Control Agreement to) deliver a revocation of such notice of control or otherwise rescind control over, and hereby agrees to no longer issue any entitlement orders or instructions with respect to, any Account or any other deposit or securities account of such Grantor over which control was previously exercised.

SECTION 6. THE COLLATERAL AGENT

6.1 Collateral Agent’s Appointment as Attorney-in-Fact, etc.

(a) Each Grantor hereby irrevocably constitutes and appoints the Collateral Agent and any officer or agent thereof, with full power of substitution, as its true and lawful attorney-in-fact with full irrevocable power and authority in the place and stead of such Grantor and in the name of such Grantor or in its own name, for the purpose of carrying out the terms of this Agreement, to take any and all appropriate action and to execute any and all documents and instruments which may be necessary or desirable to accomplish the purposes of this Agreement, and, without limiting the generality of the foregoing, each Grantor hereby gives the Collateral Agent the power and right, on behalf of such Grantor, without notice to or assent by such Grantor to do any or all of the following:

(i) in the name of such Grantor or in its own name, or otherwise, take possession of and endorse and collect any checks, drafts, notes, acceptances or other instruments for the payment of moneys due under any Receivable or with respect to any other Collateral and file any claim or take any other action or proceeding in any court of law or equity or otherwise deemed appropriate by the Collateral Agent for the purpose of collecting any and all such moneys due under any Receivable or with respect to any other Collateral whenever payable;

(ii) in the case of any Intellectual Property, execute and deliver, and have recorded, any and all agreements, instruments, documents and papers as the Collateral Agent may request to evidence the Secured Parties’ security interest in such Intellectual Property and the goodwill and general intangibles of such Grantor relating thereto or represented thereby;

(iii) pay or discharge taxes and Liens levied or placed on or threatened against the Collateral, effect any repairs or any insurance called for by the terms of this Agreement and pay all or any part of the premiums therefor and the costs thereof;

(iv) execute, in connection with any sale provided for in Section 5.6 or 5.7, any endorsements, assignments or other instruments of conveyance or transfer with respect to the Collateral; and

(v) (1) direct any party liable for any payment under any of the Collateral to make payment of any and all moneys due or to become due thereunder directly to the Collateral Agent or as the Collateral Agent shall direct; (2) ask or demand for, collect, and receive payment of and receipt for, any and all moneys, claims and other amounts due or to become due at any time in respect of or arising out of any Collateral; (3) sign and endorse any invoices, freight or express bills, bills of lading, storage or warehouse receipts, drafts against debtors, assignments, verifications, notices and other documents in connection with any of the Collateral; (4) commence and prosecute any suits, actions or proceedings at law or in equity in any court of competent jurisdiction to collect the Collateral or any portion thereof and to enforce any other right in respect of any Collateral; (5) defend any suit, action or proceeding brought against such Grantor with respect to any Collateral; (6) settle, compromise or adjust any such suit, action or proceeding and, in connection therewith, give such discharges or releases as the Collateral Agent may deem appropriate; (7) assign any Copyright, Patent or Trademark (along with the goodwill of the business to which any such Copyright, Patent or Trademark pertains), throughout the world for such term or terms, on such conditions, and in such manner, as the Collateral Agent shall in its reasonable judgment determine; and (8) generally, sell, transfer, pledge and make any agreement with respect to or otherwise deal with any of the Collateral as fully and completely as though the Collateral Agent were the absolute owner thereof for all purposes, and do, at the Collateral Agent’s option and such Grantor’s expense, at any time, or from time to time, all acts and things which the Collateral Agent deems necessary to protect, preserve or realize upon the Collateral and the Secured Parties’ security interests therein and to effect the intent of this Agreement, all as fully and effectively as such Grantor might do.

Anything in this Section 6.1(a) to the contrary notwithstanding, the Collateral Agent agrees that, except as provided in Section 6.1(b), it will not exercise any rights under the power of attorney provided for in this Section 6.1(a) unless and until an Event of Default shall have occurred and be continuing.

(b) If any Grantor fails to perform or comply with any of its agreements contained herein, the Collateral Agent, at its option, but without any obligation so to do, may perform or comply, or otherwise cause performance or compliance, with such agreement.

(c) The expenses of the Collateral Agent incurred in connection with actions undertaken as provided in this Section 6.1, together with interest thereon at the default rate of interest set forth in Section 2.12 of the Indenture, from the date of payment by the Collateral

Agent to the date reimbursed by the relevant Grantor, shall be payable by such Grantor to the Collateral Agent on demand.

(d) Each Grantor hereby ratifies all that said attorneys shall lawfully do or cause to be done by virtue hereof. All powers, authorizations and agencies contained in this Agreement are coupled with an interest and are irrevocable until this Agreement is terminated and the security interests created hereby are released.

6.2 Duty of Collateral Agent. The Collateral Agent’s sole duty with respect to the custody, safekeeping and physical preservation of the Collateral in its possession, under Section 9-207 or 9-208 of the UCC or otherwise, shall be to deal with it in the same manner as the Collateral Agent deals with similar property for its own account. Neither the Collateral Agent, nor any other Secured Party nor any of their respective officers, directors, partners, employees, agents, attorneys and other advisors, attorneys-in-fact or affiliates shall be liable for failure to demand, collect or realize upon any of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of any Grantor or any other Person or to take any other action whatsoever with regard to the Collateral or any part thereof. The powers conferred on the Secured Parties hereunder are solely to protect the Secured Parties’ interests in the Collateral and shall not impose any duty upon any Secured Party to exercise any such powers. The Secured Parties shall be accountable only for amounts that they actually receive as a result of the exercise of such powers, and neither they nor any of their officers, directors, partners, employees, agents, attorneys and other advisors, attorneys-in-fact or affiliates shall be responsible to any Grantor for any act or failure to act hereunder, except to the extent that any such act or failure to act is found by a final and nonappealable decision of a court of competent jurisdiction to have resulted solely and proximately from their own gross negligence or willful misconduct in breach of a duty owed to such Grantor.

6.3 Filing of Financing Statements. Each Grantor acknowledges that pursuant to Section 9-509(b) of the UCC and any other applicable law, each Grantor irrevocably authorizes the Collateral Agent to file or record financing or continuation statements, and amendments thereto, and other filing or recording documents or instruments with respect to the Collateral in such form and in such offices as the Collateral Agent reasonably determines appropriate to perfect or maintain the perfection of the security interests of the Collateral Agent under this Agreement; provided, that neither the Trustee nor the Collateral Agent shall be responsible or under any obligation whatsoever to file financing or continuation statements or to make any other filing under the UCC in connection therewith. Each Grantor hereby agrees that such financing statements may describe the collateral in the same manner as described in the Security Documents or as “all assets” or “all personal property” of the undersigned, whether now owned or hereafter existing or acquired by the undersigned. If and to the extent permitted by applicable law, a photographic or other reproduction of this Agreement shall be sufficient as a financing statement or other filing or recording document or instrument for filing or recording in any jurisdiction.

6.4 Authority of Collateral Agent. Each Grantor acknowledges that the rights and responsibilities of the Collateral Agent under this Agreement with respect to any action taken by the Collateral Agent or the exercise or non-exercise by the Collateral Agent of any

option, voting right, request, judgment or other right or remedy provided for herein or resulting or arising out of this Agreement shall, as between the Collateral Agent and the other Secured Parties, be governed by the Indenture and by such other agreements with respect thereto as may exist from time to time among them, but, as between the Collateral Agent and the Grantors, the Collateral Agent shall be conclusively presumed to be acting as agent for the Secured Parties with full and valid authority so to act or refrain from acting, and no Grantor shall be under any obligation, or entitlement, to make any inquiry respecting such authority. As among the Noteholders, the Trustee and the Collateral Agent, (a) the Collateral Agent will hold all items of the Collateral at any time received under this Agreement in accordance with the terms of this Agreement and the Indenture and (b) by accepting the benefits of this Agreement, each Noteholder and the Trustee acknowledges and agrees that (1) the obligations of the Collateral Agent as holder of the Collateral and any interests therein and with respect to any disposition of any of the Collateral or any interest therein, are only those obligations expressly set forth in this Agreement and the Indenture, and (2) this Agreement may be enforced only by the action of the Collateral Agent and that no other Secured Party shall have any right individually to seek to enforce or to enforce this Agreement, it being understood and agreed that such rights and remedies may be exercised by the Collateral Agent, for the benefit of the Secured Parties, upon the terms of this Agreement and the Indenture.

6.5 Appointment of Co-Agent. At any time or from time to time, in order to comply with any Legal Requirement, the Collateral Agent may appoint another bank or trust company or one or more other persons, to act as co-agent on behalf of the Secured Parties with such power and authority as may be necessary for the effectual operation of the provisions of this Agreement and which may be specified in the instrument of appointment (which may, in the discretion of the Collateral Agent, include provisions for indemnification and similar protections of such co-agent or separate agent); provided, that the Collateral Agent shall give prompt notice of such appointment to all Grantors pursuant to Section 7.2.

SECTION 7. MISCELLANEOUS

7.1 Amendments in Writing. None of the terms or provisions of this Agreement may be waived, amended, amended and restated, supplemented, replaced or otherwise modified except in writing signed by the Collateral Agent and each Grantor. Notwithstanding the foregoing, supplements or revisions to Schedules made in accordance with or as required by this Agreement shall be effective without the consent of any party hereto (other than the Grantor providing such supplement or revision).

7.2 Notices. All notices, requests and demands to or upon the Collateral Agent or any Grantor hereunder shall be effected in the manner provided for in Section 14.02 of the Indenture; provided, that any such notice, request or demand to or upon any Grantor shall be addressed to such Grantor at the following addresses:

7.3 No Waiver by Course of Conduct; Cumulative Remedies. No Secured Party shall by any act (except by a written instrument pursuant to Section 7.1), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any Default or Event of Default. No failure to exercise, nor any delay in exercising, on the part of any Secured Party, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by any Secured Party of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy which such Secured Party would otherwise have on any future occasion. The rights and remedies herein provided are cumulative, may be exercised singly or concurrently and are not exclusive of any other rights or remedies provided by law.

7.4 Enforcement Expenses; Indemnification.

(a) Each Grantor agrees to pay or reimburse each Secured Party and each Secured Parties’ respective officers, directors, employees, representatives, agents, attorneys and affiliates (each an “Indemnified Party”) for all their costs and expenses incurred in collecting against such Grantor in connection with the enforcement or preservation of any rights under this Agreement and each other document, instrument or agreement relating to the Secured Obligations to which such Grantor is a party, including, without limitation, out-of-pocket costs and expenses (including reasonable fees and disbursements of counsel to each Secured Party and of counsel to the Collateral Agent).

(b) Each Grantor agrees to pay, and to save the Indemnified Parties harmless from, any recording and filing fees and all liabilities with respect to, or resulting from any Grantor’s delay in paying stamp, excise, sales or other taxes, if any, which may be payable or determined to be payable with respect to any of the Collateral or in connection with any of the transactions contemplated by this Agreement.

(c) Each Grantor agrees to pay, and to save the Indemnified Parties harmless from, any and all liabilities, obligations, losses, damages, penalties, actions, judgments or suits of any kind or nature whatsoever with respect to the execution, delivery, enforcement, performance and administration of this Agreement; provided, that no Grantor shall have any obligation hereunder to any Indemnified Party with respect to the foregoing to the extent such liabilities,

obligations, losses, damages, penalties, actions, judgments or suits may be attributable to the gross negligence or willful misconduct of such Indemnified Party.

(d) The agreements in this Section 7.4 shall survive repayment of the Secured Obligations and all other amounts payable under any document, instrument or agreement relating to the Secured Obligations. The indemnification provided for in this Section 7.4 is in addition to, and not in limitation of, any other indemnification or insurance provided by each Grantor to any Secured Party.

7.5 Successors and Assigns. This Agreement shall be binding upon the successors and assigns of each Grantor and shall inure to the benefit of the Secured Parties and their respective successors and assigns; provided, that no Grantor may assign, transfer or delegate any of its rights or obligations under this Agreement (i) without the prior written consent of the Collateral Agent and (ii) by operation of law or otherwise, except as permitted under the Indenture. The Person serving as Collateral Agent shall have the right to assign this Agreement and the other Collateral Agreements to the extent that such Person is no longer serving as the Trustee in accordance with Section 8.08 of the Indenture.

7.6 Set-Off. Each Grantor hereby irrevocably authorizes the Collateral Agent at any time and from time to time while an Event of Default shall have occurred and be continuing, without notice to such Grantor or any other Grantor, any such notice being expressly waived by each Grantor, to set-off and appropriate and apply any and all deposits (general or special, time or demand, provisional or final), in any currency, and any other credits, indebtedness or claims, in any currency, in each case whether direct or indirect, absolute or contingent, matured or unmatured, at any time held or owing by the Collateral Agent to or for the credit or the account of such Grantor, or any part thereof in such amounts as the Collateral Agent may elect, against and on account of the obligations and liabilities of such Grantor to Collateral Agent or the other Secured Parties hereunder and claims of every nature and description of the Collateral Agent or the other Secured Parties against such Grantor, in any currency, whether arising hereunder, under the Indenture, any other Note Document or otherwise, as the Collateral Agent may elect, whether or not the Collateral Agent has made any demand for payment and although such obligations, liabilities and claims may be contingent or unmatured. The Collateral Agent shall notify such Grantor promptly of any such set-off and the application made by the Collateral Agent of the proceeds thereof, provided, that the failure to give such notice shall not affect the validity of such set-off and application. The rights of the Collateral Agent and the other Secured Parties under this Section 7.6 are in addition to other rights and remedies (including, without limitation, other rights of set-off) which the Collateral Agent or the other Secured Parties may have.

7.7 Counterparts. This Agreement may be executed by one or more of the parties to this Agreement on any number of separate counterparts (including by facsimile), and all of said counterparts taken together shall be deemed to constitute one and the same instrument.

7.8 Severability. Any provision of this Agreement which 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 any

such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

7.9 Section Headings. The Section headings used in this Agreement are for convenience of reference only and are not to affect the construction hereof or be taken into consideration in the interpretation hereof.

7.10 Integration. This Agreement, the other Note Documents and the Intercreditor Agreement represent the agreement of the Grantors, the Collateral Agent and the other Secured Parties with respect to the subject matter hereof and thereof, and there are no promises, undertakings, representations or warranties by any Secured Party relative to subject matter hereof and thereof not expressly set forth or referred to herein, in the other Note Documents and the Intercreditor Agreement.

7.11 GOVERNING LAW. SUBJECT TO COMPLIANCE WITH PROVISIONS OF MANDATORY NEW YORK LAW WHICH MAY REQUIRE APPLICATION OF DELAWARE LAW AS TO CERTAIN ISSUES OF PERFECTION, THE EFFECT OF PERFECTION OR NON-PERFECTION, AND THE PRIORITY OF SECURITY INTERESTS, THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

7.12 Submission to Jurisdiction; Waivers. Each Grantor hereby irrevocably and unconditionally:

(a) submits for itself and its property in any legal action or proceeding relating to this Agreement and any other instruments, documents or agreements relating to the Secured Obligations to which it is a party, or for recognition and enforcement of any judgment in respect thereof, to the non-exclusive general jurisdiction of the Courts of the State of New York, the courts of the United States of America for the Southern District of New York, and appellate courts from any thereof;

(b) consents that any such action or proceeding may be brought in such courts and waives any objection that it may now or hereafter have to the venue of any such action or proceeding in any such court or that such action or proceeding was brought in an inconvenient court and agrees not to plead or claim the same;

(c) agrees that service of process in any such action or proceeding may be effected by mailing a copy thereof by registered or certified mail (or any substantially similar form of mail), postage prepaid, to such Grantor at its address referred to in Section 7.2 or at such other address of which the Collateral Agent shall have been notified pursuant thereto;

(d) agrees that nothing herein shall affect the right to effect service of process in any other manner permitted by law or shall limit the right to ▇▇▇ in any other jurisdiction; and

(e) waives, to the maximum extent not prohibited by law, any right it may have to claim or recover in any legal action or proceeding referred to in this Section any special, exemplary, punitive or consequential damages.

7.13 Waivers by FiberTower. FiberTower hereby waives, for the benefit of the Secured Parties:

(a) any right to require any Secured Party, as a condition of payment or performance by FiberTower, to (i) proceed against any other Grantor or any other Person, (ii) proceed against or exhaust any security held from any other Grantor or any other Person, (iii) proceed against or have resort to any balance of any deposit account or credit on the books of any Secured Party in favor of any Grantor or any other Person, or (iv) pursue any other remedy in the power of any Secured Party whatsoever;

(b) any defense arising by reason of the incapacity, lack of authority or any disability or other defense of any Grantor including any defense based on or arising out of the lack of validity or the unenforceability of any of the Secured Obligations or any agreement or instrument relating thereto or by reason of the cessation of the liability of any Grantor from any cause other than payment in full of all Obligations under the Indenture and the other Note Documents;

(c) any defense based upon any statute or rule of law which provides that the obligation of a surety must be neither larger in amount nor in other respects more burdensome than that of the principal;

(d) any defense based upon any Secured Party’s administrative errors or omissions, except behavior which amounts to bad faith;

(e) (i) any principles or provisions of law, statutory or otherwise, which are or might be in conflict with the terms of this Agreement and any legal or equitable discharge of FiberTower’s obligations hereunder, (ii) the benefit of any statute of limitations affecting FiberTower’s liability hereunder or the enforcement hereof, (iii) any rights to set-offs, recoupments and counterclaims, and (iv) promptness, diligence and any requirement that any Secured Party protect, secure, perfect or insure any security interest or lien or any property subject thereto;

(f) notices, demands, presentments, protests, notices of protest, notices of dishonor and notices of any action or inaction, including acceptance of this Agreement, notices of default under the Indenture or any agreement or instrument related thereto, notices of any renewal, extension or modification of the Secured Obligations or any agreement related thereto and notices of any extension of credit to the Grantors; and

(g) any defenses or benefits that may be derived from or afforded by law which limit the liability of or exonerate guarantors or sureties, or which may conflict with the terms of this Agreement.

7.14 Acknowledgments. Each Grantor hereby acknowledges that:

(a) it has been advised by counsel in the negotiation, execution and delivery of this Agreement;

(b) no Secured Party has any fiduciary relationship with or duty to any Grantor arising out of or in connection with this Agreement or any of the other Note Documents, and the relationship between the Grantors, on the one hand, and the Secured Parties, on the other hand, in connection herewith or therewith is solely that of debtor and creditor; and

(c) no joint venture is created hereby or by any other documents, agreements or instruments relating to the Secured Obligations or otherwise exists by virtue of the transactions contemplated hereby among the Secured Parties or among the Grantors and the Secured Parties.

7.15 Additional Grantors. Each Affiliate of FiberTower that is required to become a party to this Agreement pursuant to any document, agreement or instrument relating to the Secured Obligations shall become a Grantor for all purposes of this Agreement upon execution and delivery by such Affiliate of an Assumption Agreement in the form of Annex 1 hereto.

7.16 Releases.

(a) At such time as the Secured Obligations (other than unmatured contingent reimbursement and indemnification obligations) shall have been Discharged, the Collateral shall be released from the Liens created hereby, and this Agreement and all obligations (other than those expressly stated to survive such termination) of the Collateral Agent and each Grantor hereunder shall terminate, all without delivery of any instrument or performance of any act by any party, and all rights to the Collateral shall revert to the Grantors. At the request and sole expense of any Grantor following any such termination, the Collateral Agent shall deliver to such Grantor any of such Grantor’s Collateral held by the Collateral Agent hereunder, and execute and deliver to such Grantor such documents as such Grantor shall reasonably request to evidence such termination.

(b) In the case of any Released Assets, the Collateral Agent, at the request and sole expense of such Grantor, shall execute and deliver to such Grantor all releases or other documents reasonably necessary or desirable for the release of the Liens created hereby on such Collateral.

(c) Each Grantor acknowledges that it is not authorized to file any financing statement or amendment or termination statement with respect to any financing statement originally filed in connection herewith without the prior written consent of the Collateral Agent subject to such Grantor’s rights under Section 9-509(d)(2) of the UCC.

7.17 WAIVER OF JURY TRIAL. EACH GRANTOR AND THE COLLATERAL AGENT HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER NOTE DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN.

7.18 Certain Regulatory Requirements. Any provision herein or in any other agreement to the contrary notwithstanding, the Collateral Agent will not take any action pursuant to this Agreement, or any other agreement between any Grantor and the Collateral Agent, or any

other agreement with respect to the Notes, the Indenture, the Intercreditor Agreement, or the Noteholders, that would constitute or result in any de facto or de jure assignment of an FCC License or transfer of control of any Grantor, if such assignment of license or transfer of control would require under then existing law (including the Communications Act), the prior approval of the FCC, without first obtaining such approval of the FCC. Any disposition of the Pledged Stock will be conducted in accordance with the then applicable requirements of the Communications Act. Each Grantor agrees that, if an Event of Default shall have occurred and be continuing, upon request from time to time by the Collateral Agent during such circumstance it shall use all commercially reasonable efforts to obtain any governmental authorizations referred to in this Section 7.18, including upon any request of the Collateral Agent following the occurrence and during the continuance of an Event of Default, to prepare, sign and file with the FCC (or cause to be prepared signed and filed with the FCC) any application or applications that are necessary or appropriate under the FCC’s rules and regulations for consent to the assignment of the FCC Licenses held by such Grantor or to the transfer of control of such Grantor.

7.19 Subordination. The security interests securing the indebtedness and other obligations under the Indenture, the Notes and the Note Guarantees (as defined in the Indenture) will be subordinated to the security interests securing any future indebtedness and other obligations under a certain senior secured Working Capital Facility that FiberTower and one or more Guarantors may enter into after the date of the Indenture. A copy of the form of Intercreditor Agreement governing such subordination is available from FiberTower upon written request.

Exhibit D to
Pledge and Security Agreement

FORM OF CONTROL AGREEMENT

This CONTROL AGREEMENT (as amended, amended and restated, supplemented, replaced or otherwise modified from time to time, the “Control Agreement”), dated as of [ ], 200[ ], among (the “Grantor”), in its capacity as a “securities intermediary” (as defined in Section 8-102 of the UCC) and a “bank” (as defined in Section 9-102 of the UCC) (in such capacities, the “Financial Institution”), and ▇▇▇▇▇ Fargo Bank, National Association, as collateral agent under the Security Agreement (as defined below) for and on behalf of the Secured Parties (as defined therein) (together with its successors and assigns in such capacity, the “Collateral Agent”). All references herein to the “UCC” shall mean the Uniform Commercial Code as from time to time in effect in the State of New York.

WHEREAS, [the Grantor], [ ], [ ] and ▇▇▇▇▇ Fargo Bank, National Association, in its capacity as trustee on behalf of the holders of the notes issued from time to time thereunder, have entered into that certain Indenture, dated as of November 9, 2006 (as amended, amended and restated, supplemented, replaced or otherwise modified from time to time, the “Indenture”);

WHEREAS, the Grantor has granted to the Collateral Agent, for the benefit of the Secured Parties, a security interest in the Pledged Accounts (as hereinafter defined) pursuant to that certain Pledge and Security Agreement, dated as of November 9, 2006 (as amended, amended and restated, supplemented, replaced or otherwise modified from time to time, the “Security Agreement”), among the Grantor and the other persons party thereto as grantors in favor of the Collateral Agent; and

WHEREAS, the parties hereto are entering into this Control Agreement to perfect and ensure the priority of such security interest.

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

SECTION 1. Establishment and Maintenance of Collateral Accounts.

(a) The Financial Institution hereby represents and warrants that it has established and currently maintains the accounts listed on Schedule 1 hereto and that the Grantor is its sole customer or entitlement holder with respect to each such account. Each such account and any successor account and all other accounts which the Grantor now or hereafter maintains with the Financial Institution, shall be referred to herein individually as a “Pledged Account” and collectively as the “Pledged Accounts.” The Financial Institution covenants and agrees that it shall not change the name or account number of any Pledged Account without the prior written consent of the Collateral Agent.

(b) Each of the parties hereto acknowledges and agrees that the accounts listed on Part A of Schedule 1 hereto are “deposit accounts” (within the meaning of

D-1

Section 9-102(a)(29) of the UCC) and the accounts listed on Part B of Schedule 1 hereto are “securities accounts” (within the meaning of Section 8-501 of the UCC). As used herein “Deposit Account” shall mean any Pledged Account (or any part thereof) which is determined to be a “deposit account” (within the meaning of Section 9-102(a)(29) of the UCC) and “Securities Account” shall mean any Pledged Account (or any part thereof) which is determined to be a “securities account” (within the meaning of Section 8-501 of the UCC).

(c) The Financial Institution covenants and agrees that: (i) all securities or other property underlying any financial assets credited to any Securities Account shall be registered in the name of the Financial Institution, indorsed to the Financial Institution or indorsed in blank or credited to another securities account maintained in the name of the Financial Institution and in no case will any financial asset credited to any Securities Account be registered in the name of the Grantor, payable to the order of the Grantor or specially indorsed to the Grantor except to the extent the foregoing have been specially indorsed to the Financial Institution or in blank; and (ii) all property delivered to the Financial Institution pursuant to the Security Agreement will be promptly credited to one of the Pledged Accounts.

SECTION 2. “Financial Assets” Election. The Financial Institution hereby agrees that each item of property (including, without limitation, all investment property, financial assets, securities, instruments or cash) credited to any Pledged Account that is a Securities Account shall be treated as a “financial asset” within the meaning of Section 8-102(a)(9) of the UCC.

SECTION 3. Control of the Pledged Accounts. If at any time the Financial Institution shall receive from the Collateral Agent an entitlement order (i.e. an order directing transfer or redemption of any financial asset relating to a Pledged Account) or any instruction directing disposition of funds in a Pledged Account originated by the Collateral Agent, the Financial Institution shall comply with such entitlement order or instruction without further consent by the Grantor or any other person. The Grantor is entitled to give entitlement orders and instructions with respect to the Pledged Accounts, subject to Section 4 hereof, provided, that if such entitlement orders or instructions conflict with instructions of the Collateral Agent, the Financial Institution shall comply with the entitlement orders and instructions issued by the Collateral Agent. The intent of the foregoing is to perfect the security interest of the Collateral Agent for the benefit of the Securities Parties granted pursuant to the Security Agreement.

SECTION 4. Grantor’s Access to the Account. If at any time the Collateral Agent delivers to the Financial Institution a Notice of Sole Control in substantially the form set forth in Exhibit A hereto, the Financial Institution agrees that, after receipt of such notice, it will take all directions with respect to the Pledged Accounts solely from the Collateral Agent and shall not comply with instructions or entitlement orders of the Grantor or any other person (unless and until the Collateral Agent instructs otherwise).

SECTION 5. Subordination of Lien; Waiver of Set-Off. In the event that the Financial Institution has or subsequently obtains by agreement, by operation of law or otherwise a security interest in any Pledged Account or any financial assets, cash or other property credited thereto, the Financial Institution hereby agrees that such security interest shall be subordinate to the security interest of the Collateral Agent perfected hereby. The financial assets, money and

D-2

other items credited to any Pledged Account will not be subject to deduction, set-off, banker’s lien, or any other right in favor of any person other than the Collateral Agent (except that the Financial Institution may set off (i) all amounts due to the Financial Institution in respect of customary fees and expenses for the routine maintenance and operation of the respective Pledged Account and (ii) the face amount of any checks which have been credited to such Pledged Account but are subsequently returned unpaid because of uncollected or insufficient funds).

SECTION 6. Choice of Law. THIS CONTROL AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK. Regardless of any provision in any other agreement, for purposes of the UCC, with respect to each Pledged Account, the State of New York shall be deemed to be the Financial Institution’s jurisdiction (within the meaning of Sections 8-110 and 9-304 of the UCC). The Pledged Accounts shall be governed by the laws of the State of New York.

SECTION 7. Conflict with Other Agreements. The Financial Institution hereby represents, warrants, covenants and agrees that:

(a) There are no other agreements entered into between the Financial Institution and the Grantor with respect to any Pledged Account [except for [identify other agreements]] (the “Account Agreements”).

(b) It has not entered into, and until the termination of this Control Agreement will not enter into, any agreement with any other person relating to the Pledged Accounts and/or any financial assets credited thereto pursuant to which it has agreed to comply with entitlement orders of such other person (as defined in Section 8-102(a)(8) of the UCC) or instructions of such other person directing the disposition of funds (except any such other agreement with the Grantor under which the obligations of the Financial Institution are subordinated to the Financial Institution’s obligations hereunder).

(c) It has not entered into, and until the termination of this Control Agreement will not enter into, any agreement with the Grantor purporting to limit or condition the obligation of the Financial Institution to comply with entitlement orders or instructions from the Collateral Agent.

(d) Except as provided in Section 6 above, in the event of any conflict between this Control Agreement (or any portion thereof) and any other agreement now existing or hereafter entered into, the terms of this Control Agreement shall prevail.

SECTION 8. Adverse Claims. The Financial Institution represents and warrants that, except for the claims and interest of the Grantor and the Collateral Agent in each case as described herein, in the Pledged Accounts, it does not know of any lien on or claim to, or interest in, any Pledged Account or in any “financial asset” (as defined in Section 8-102(a) of the UCC) credited thereto. If any person asserts any lien, encumbrance or adverse claim (including any writ, garnishment, judgment, warrant of attachment, execution or similar process) against the Pledged Accounts or in any financial asset carried therein, the Financial Institution will promptly notify the Collateral Agent and the Grantor thereof upon becoming aware of such assertion.

D-3

SECTION 9. Additional Provisions Regarding Maintenance of Accounts. The Financial Institution covenants and agrees:

(a) Statements and Confirmations. The Financial Institution will promptly send copies of all statements, confirmations and other correspondence concerning (i) any Securities Account and/or any financial assets credited thereto and (ii) any Deposit Account, simultaneously to each of the Grantor and the Collateral Agent at the address for each set forth in Section 13 of this Control Agreement.

(b) Tax Reporting. All items of income, gain, expense and loss recognized in any Securities Account and all interest, if any, relating to any Deposit Account, shall be reported to the Internal Revenue Service and all state and local taxing authorities under the name and taxpayer identification number of the Grantor.

(c) Voting Rights. At any time during which the Grantor is entitled to give entitlement orders pursuant to Section 3 hereof, the Grantor shall direct the Financial Institution with respect to the voting of any financial assets credited to the Pledged Accounts.

(d) Permitted Investments. At any time during which the Grantor is entitled to give entitlement orders pursuant to Section 3 hereof, the Grantor shall direct the Financial Institution with respect to the selection of investments to be made for any Pledged Account that is a Securities Account; provided, however, that the Financial Institution shall not honor any instruction to purchase any investments other than investments of a type described as “Cash Equivalents” on Exhibit B hereto.

SECTION 10. Additional Representation and Warranty of the Financial Institution. The Financial Institution represents and warrants that this Control Agreement is the legal, valid, binding and enforceable obligation of the Financial Institution.

SECTION 11. Indemnification of Financial Institution. The Grantor and the Collateral Agent hereby agree that (a) the Financial Institution is released from any and all liabilities to the Grantor and the Collateral Agent arising from the terms of this Control Agreement and the compliance of the Financial Institution with the terms hereof, except to the extent that such liabilities arise from the Financial Institution’s gross negligence or willful misconduct and (b) the Grantor, its successors and assigns shall at all times indemnify and save harmless the Financial Institution from and against any and all claims, actions and suits of others arising out of the terms of this Control Agreement or the compliance of the Financial Institution with the terms hereof, except to the extent that such arises from the Financial Institution’s negligence, and from and against any and all liabilities, losses and damages and reasonable costs, charges, counsel fees and other expenses of every nature and character arising by reason of the same, until the termination of this Control Agreement.

SECTION 12. Successors; Assignment. The terms of this Control Agreement shall be binding upon, and shall inure to the benefit of, the parties hereto and their respective corporate successors and assigns, except that the neither the Grantor nor the Financial Institution may assign their obligations hereunder without the prior written consent of the Collateral Agent. Additionally, in the event that the Collateral Agent is replaced as Collateral Agent under the

D-4

Security Agreement, any entity that succeeds to such role shall be entitled to the benefits of this Control Agreement. The Collateral Agent agrees to send written notice to the Financial Institution of any such replacement.

WHEREAS, the Broker maintains for the Grantor a commodity account, Account No. , in the name of the Grantor (the “Pledged Account”);

WHEREAS, the Grantor has granted to the Collateral Agent, for the benefit of the Secured Parties, a security interest in the Pledged Account, the commodity contracts and any free credit balance carried therein, and all additions thereto and substitutions and proceeds thereof (collectively, the “Collateral”) pursuant to that certain Pledge and Security Agreement, dated as of November 9, 2006 (as amended, amended and restated, supplemented, replaced or otherwise modified from time to time, the “Security Agreement”), among the Grantor and the other persons party thereto as grantors in favor of the Collateral Agent; and

WHEREAS, the following terms, which are defined in Articles 8 and 9 of the Uniform Commercial Code in effect in the State of New York on the date hereof (the “UCC”), are used herein as so defined: commodity account, commodity contract, commodity intermediary’s jurisdiction, control and proceeds.

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

SECTION 1. Notice of Security Interest. The Grantor, the Collateral Agent and the Broker are entering into this Control Agreement to perfect, and to confirm the priority of, the Collateral Agent’s security interest in the Collateral. The Broker acknowledges that this Control Agreement constitutes written notification to the Broker of the Collateral Agent’s security interest in the Collateral. The Broker agrees to promptly make all necessary entries or notations in its books and records to reflect the Collateral Agent’s security interest in the Collateral. The Broker acknowledges that the Collateral Agent has control over the Pledged Account and all commodity contracts and any free credit balance carried therein from time to time.

E-1

SECTION 2. Collateral; Pledged Account. (a) The Grantor hereby represents and warrants to, and agrees with the Collateral Agent and the Broker that, all commodity contracts carried by the Broker on its books for the Grantor are and shall be credited to the Pledged Account.

(a) The Broker hereby represents and warrants to, and agrees with the Grantor and the Collateral Agent that, (i) the Broker is a commodity intermediary with respect to the Grantor and the Pledged Account is a commodity account, (ii) the commodity intermediary’s jurisdiction (within the meaning of Section 9-305(b) of the UCC) is, and during the term of this Control Agreement shall for all purposes of this Control Agreement remain, the State of New York, (iii) Schedule 1 contains a true and complete statement of the Pledged Account and the commodity contracts and any free credit balance carried therein as of the date hereof, and (iv) no commodity contracts carried in the Pledged Account shall be purchases on margin, and the Broker will not extend, directly or indirectly, any “purpose credit” (within the meaning of such term under Regulation T of the Board of Governors of the Federal Reserve System of the United States) to the Grantor in respect of the Pledged Account.

(b) The Collateral Agent hereby instructs the Broker, and the Broker hereby confirms and agrees that, unless the Collateral Agent shall otherwise direct the Broker in writing, all commodity contracts carried by the Broker on its books for the Grantor shall be credited only to, and carried only in, the Pledged Account.

SECTION 3. Control. The Broker hereby agrees, upon written direction from the Collateral Agent and without further consent from the Grantor, (a) to apply any value distributed on account of the commodity contracts carried in the Pledged Account as directed by the Collateral Agent, to liquidate or otherwise dispose of the Collateral as and to the extent directed by the Collateral Agent and to pay over to the Collateral Agent all proceeds and other value therefrom or otherwise distributed with respect thereto without any setoff or deduction, and (b) except as otherwise directed by the Collateral Agent, not to apply any value distributed on account of any commodity contract carried in the Pledged Account as directed by the Grantor or any other person at any time after the Broker has received written notice from the Collateral Agent that it is no longer permitted to so apply any value distributed on account of any commodity contract carried in the Pledged Account (and thereafter not until such time as the Collateral Agent sends written notice to the Broker that it is permitted to so apply any value distributed on account of any commodity contract carried in the Pledged Account). Until such time as the Broker has received written notice from the Collateral Agent that it is not permitted to apply any value distributed on account of the commodity contracts carried in the Pledged Account as directed by the Grantor, the Grantor shall be entitled to issue directions concerning the application of any value distributed on account of any commodity contract carried in the Pledged Account, and the Broker shall comply with such directions; provided, however, that if and when the Broker receives conflicting directions from the Grantor and the Collateral Agent, the Bank shall only follow the directions of the Collateral Agent. The intent of the foregoing is to perfect the security interest of the Collateral Agent for the benefit of the Secured Parties granted pursuant to the Security Agreement.

SECTION 4. Other Agreements; Termination; Successor Brokers. The Broker shall simultaneously send to the Collateral Agent copies of all notices given and statements

E-2

rendered to the Grantor with respect to the Pledged Account. The Broker shall notify promptly the Collateral Agent and the Grantor if any other person asserts any lien, encumbrance, claim or security interest in or against any of the Collateral. As long as this Control Agreement remains in effect, neither the Grantor nor the Broker shall terminate the Pledged Account without thirty (30) days’ prior written notice to the other party and the Collateral Agent. Except as provided in Section 4 above, in the event of any conflict between the provisions of this Control Agreement and any other agreement governing any Collateral, the provisions of this Control Agreement shall control. In the event the Broker no longer serves as Broker for the Collateral, the Pledged Account, the commodity contracts and any free credit balance carried therein shall be transferred to a successor broker, custodian or futures commission merchant satisfactory to the Collateral Agent, provided, that prior to such transfer, such successor broker, custodian or futures commission merchant shall execute an agreement that is substantially in the form of this Control Agreement or is otherwise in form and substance satisfactory to the Collateral Agent.

SECTION 5. Protection of Broker. The Broker may rely and shall be protected in acting upon any notice, instruction or other communication that it reasonably believes to be genuine and authorized.

SECTION 6. Termination. This Control Agreement shall terminate automatically upon receipt by the Broker of written notice executed by the Collateral Agent that (i) all of the obligations (excluding unmatured contingent reimbursement and indemnification obligations) secured by the Collateral have been satisfied in accordance with any agreements applicable thereto, or (ii) the security interest in all of the Collateral has been released, whichever is sooner, and the Broker shall thereafter be relieved of all duties and obligations hereunder. Upon request by the Grantor, the Collateral Agent agrees to provide a Notice of Termination in substantially the form of Exhibit A hereto to the Broker upon the termination of this Control Agreement in accordance with the foregoing.

SECTION 7. Waiver; Priority of Collateral Agent’s Interests. Other than with respect to its fees and customary commissions with respect to the Pledged Account, the Broker hereby waives its right to set off any obligations of the Grantor to the Broker against any or all of the Collateral, and hereby agrees that any and all liens, encumbrances, claims or security interests which the Broker may have against the Collateral, either now or in the future in connection with the Pledged Account are and shall be subordinate and junior to the prior payment in full in immediately available funds of all obligations of the Grantor now or hereafter existing under the Indenture, the Security Agreement and all other documents related thereto, whether for principal, interest (whether or not such interest accrues after the filing of such petition for purposes of the federal Bankruptcy Code or is an allowed claim in such proceeding), indemnities, fees, premiums, expenses or otherwise. Except for the foregoing and claims and interests of the Grantor and the Collateral Agent as described herein in the Collateral, the Broker does not know of any claim to or security interest or other interest in the Collateral.
