(b) No Conflicts or Consents. Neither the ownership or the intended use of the Collateral by Pledgor, nor the grant of the security interest by Pledgor to Pledgee herein, nor the exercise by Pledgee of its rights or remedies hereunder, will (i) conflict with any provision of (A) any domestic or foreign law, statute, rule or regulation, (B) the certificate of formation, articles of organization, limited liability company agreement, or other organizational document of the JV Company, or (C) any agreement, judgment, license, order or permit applicable to or binding upon Pledgor; or (ii) result in or require the creation of any Lien, charge or encumbrance upon any assets or properties of Pledgor except as expressly contemplated in the Loan Documents.

Execution Version

other registration to exist or deliver actual or constructive possession of the Collateral to any other Person other than Liens in favor of Pledgee and those provided in Section 3.1(d)(iv).

Without limitation of any other covenant herein, Pledgor will not cause or permit any change to be made in its name, identity, corporate structure or jurisdiction of organization, or any change to be made to a jurisdiction in (i) the location of any records concerning any Collateral, or (ii) the location of its chief executive office, chief place of business or principal place of residence, unless Pledgor shall have notified Pledgee of such change at least fifteen (15) days prior to the effective date of such change, and shall have first taken all action reasonably required by Pledgee for the purpose of further perfecting or protecting the security interest in favor of Pledgee in the Collateral. In any notice furnished pursuant to this subsection, Pledgor will expressly state that the notice is required by this Agreement and contains facts that may require additional filings of financing statements or other notices for the purposes of continuing perfection of Pledgee’s security interest in the Collateral.

(b) Power of Attorney. Pledgor hereby irrevocably appoints Pledgee as Pledgor’s attorney-in-fact and proxy, with full authority in the place and stead of Pledgor and in the name of Pledgor or otherwise, from time to time if an Event of Default shall have occurred and be continuing, in Pledgee’s discretion but subject to the Subordination Agreement, to take any action (except for the exercise of any voting rights pertaining to the Pledged Equity or any part thereof) and to execute any instrument, certificate or notice which Pledgee may deem necessary or advisable to accomplish the purposes of this Agreement including: (i) to request or instruct Pledgor or the JV Company (and each registrar, transfer agent, or similar Person acting on behalf of Pledgor or the JV Company) to register the Pledged Equity or transfer the Collateral to Pledgee; (ii) to otherwise give notification to Pledgor, the JV Company, registrar, transfer agent, financial intermediary, or other Person of Pledgee’s security interests hereunder; (iii) to ask, demand, collect, sue for, recover, compound, receive and give acquittance and receipts for moneys due and to become due under or in respect of any of the Collateral; (iv) to receive, indorse and collect any drafts or other instruments, documents and chattel paper; (v) to file any claims or take any action or institute any proceedings which Pledgee may deem necessary or desirable for the collection of any of the Collateral or otherwise to enforce the rights of Pledgee with respect to any of the Collateral, and (vi) to act as its proxy and attorney-in-fact with respect to the Pledged Equity, including, subject to Section 4.7 hereof, the right to vote such Pledged Equity, with full power of substitution to do so, and to exercise all other rights, powers, privileges, and remedies to which a holder of such Pledged Equity would be entitled, which proxy shall be effective automatically, and without the necessity of any action (including any transfer of any such Pledged Equity on the record books of the JV Company) by any person, in each case, only upon the occurrence and during the continuance of an Event of Default.

(c) Performance by Pledgee. If Pledgor fails to perform any agreement or obligation contained herein, Pledgee may, at the direction of the Requisite Lenders, itself perform, or cause performance of, such agreement or obligation, and the expenses of Pledgee incurred in connection therewith shall be payable by Pledgor under Section 4.4 hereof.

(d) Collection Rights. Pledgee shall have the right at any time, if an Event of Default shall have occurred and be continuing, subject to the terms of the Subordination Agreement (with respect to the Collateral Pledged hereunder) to notify any or all obligors (including any and all Credit Parties) under any accounts or general intangibles included among the Collateral of the assignment thereof to Pledgee and to direct such obligors to make payment of all amounts due or to become due to Pledgor thereunder directly to Pledgee and, upon such notification and at the expense of Pledgor or the JV Company and to the extent permitted by law, to enforce collection thereof and to adjust, settle or compromise the amount or payment thereof, in the same manner and to the same extent as Pledgor could have done. After Pledgor receives

Execution Version

notice that Pledgee has given any notice referred to above in this subsection, (i) all amounts and proceeds (including instruments and writings) received by Pledgor in respect of such accounts or general intangibles shall be received in trust for the benefit of Pledgee hereunder, shall be segregated from other funds of Pledgor and shall be forthwith paid over to Pledgee or, prior to the payment in full of the JV Company Credit Facility Obligations, to the JV Company Credit Facility Agent (as agent for perfection for the Pledgee) in the same form as so received (with any necessary indorsement) to be held as cash collateral and (A) released to Pledgor upon the remedy of all Events of Default, or (B) if any Event of Default shall have occurred and be continuing, applied as specified in Section 4.3 hereof; and (ii) Pledgor will not adjust, settle or compromise the amount or payment of any such account or general intangible or release wholly or partly any account debtor or obligor thereof (including the JV Company) or allow any credit or discount thereon.

(b) require Pledgor to, and Pledgor hereby agrees that it will upon request of Pledgee forthwith, assemble all or part of the Collateral as directed by Pledgee and make it available to Pledgee at a place to be designated by Pledgee which is reasonably convenient to both parties;

(c) reduce its claim to judgment against Pledgor or foreclose or otherwise enforce, in whole or in part, the security interest created hereby by any available judicial procedure;

(d) dispose of, at its office, on the premises of Pledgor or elsewhere, all or any part of the Collateral, as a unit or in parcels, by public or private proceedings, and by way of one or more contracts (it being agreed that the sale of any part of the Collateral shall not exhaust Pledgee’s power of sale, but sales may be made from time to time, and at any time, until all of the Collateral has been sold or until the Obligations have been paid and performed in full), and at any such sale it shall not be necessary to exhibit any of the Collateral;

(e) buy (or allow any Secured Party to buy) the Collateral, or any part thereof, at any public sale;

Execution Version

Pledgor agrees that, to the extent notice of sale shall be required by law, at least ten (10) days’ notice to Pledgor 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. Pledgee shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. Pledgee 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.

Section 4.3 Application of Proceeds. If any Event of Default shall have occurred and be continuing, Pledgee may in its discretion and subject to the Subordination Agreement apply any cash held by Pledgee as Collateral, and any cash proceeds received by Pledgee in respect of any sale of, collection from, or other realization upon all or any part of the Collateral, in the order and manner contemplated by Section 7.6 of the Credit Agreement.

Section 4.4 Release and Expenses. In addition to, and not in qualification of, any similar obligations under other Loan Documents:

(a) Pledgor agrees to pay or reimburse the Pledgee or any Lender for all its reasonable out-of-pocket costs and expenses incurred in enforcing or preserving any rights under this Agreement, including, without limitation, the reasonable fees and disbursements of counsel to the Pledgee to the same extent the Borrower would be required to do so pursuant to Section 10.4 of the Credit Agreement.

(b) Pledgor agrees to pay, and to indemnify and save the Pledgee and the other Secured Parties harmless from, any and all liabilities with respect to, or resulting from any delay in paying, any and all stamp, excise, sales or other taxes 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) Pledgor agrees to pay, and to indemnify and save the Pledgee and the other Secured Parties harmless from, any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever with respect to the execution, delivery, enforcement, performance and administration of this Agreement to the same extent the Borrower would be required to do so pursuant to Section 10.7 of the Credit Agreement.

Section 4.5 Non-Judicial Remedies. In granting to Pledgee the power to enforce its rights hereunder without prior judicial process or judicial hearing, Pledgor expressly waives, renounces and knowingly relinquishes any legal right which might otherwise require Pledgee to enforce its rights by judicial process. In so providing for non-judicial remedies, Pledgor recognizes and concedes that such remedies are consistent with the usage of trade, are responsive to commercial necessity, and are the result of a bargain at arm’s length. Nothing herein is intended to prevent Pledgee or Pledgor from resorting to judicial process at either party’s option.

Section 4.6 Other Recourse. Pledgor waives any right to require Pledgee or the other Secured Parties to proceed against any other Person, exhaust any Collateral or other security for the Obligations, or to have any Other Liable Party joined with Pledgor in any suit arising out of

9

Execution Version

the Obligations or this Agreement, or pursue any other remedy in Pledgee’s power. Pledgor further waives any and all notice of acceptance of this Agreement and of the creation, modification, rearrangement, renewal or extension for any period of any of the Obligations from time to time. Pledgor further waives any defense arising by reason of any disability or other defense of any Other Liable Party or by reason of the cessation from any cause whatsoever of the liability of any Other Liable Party. Until all of the Obligations shall have been paid in full, Pledgor shall have no right to subrogation and Pledgor waives the right to enforce any remedy which Pledgee or any other Secured Party has or may hereafter have against any Other Liable Party, and waives any benefit of and any right to participate in any other security whatsoever now or hereafter held by Pledgee. Pledgor authorizes Pledgee and each other Secured Party, without notice or demand and without any reservation of rights against Pledgor and without affecting Pledgor’s liability hereunder or on the Obligations, from time to time to (a) take or hold any other property of any type from any other Person as security for the Obligations, and exchange, enforce, waive and release any or all of such other property; (b) renew, extend for any period, accelerate, modify, compromise, settle or release any of the obligations of any Other Liable Party in respect to any or all of the Obligations or other security for the Obligations; (c) waive, enforce, modify, amend or supplement any of the provisions of any Loan Document with any Person other than Pledgor; and (d) release or substitute any Other Liable Party.

Section 4.7 Voting Rights, Dividends Etc. in Respect of Pledged Equity.

(a) So long as no Event of Default shall have occurred and be continuing and the JV Company is not otherwise prohibited from making such dividends, distributions or payments pursuant to the JV Credit Agreement, including, without limitation, any “Permitted Tax Distributions” and “Economic Interest Agreement Payments” (each as defined in the JV Credit Agreement), Pledgor may receive and retain any and all dividends, distributions or interest paid in respect of the Pledged Equity; provided, however, that any and all dividends, distributions and interest paid or payable other than in cash in respect of, and instruments and other property received, receivable or otherwise distributed in respect of or in exchange for, any Pledged Equity, shall be, and shall forthwith be delivered to Pledgee (or to the JV Company Credit Facility Agent, as bailee for perfection under the Intercreditor Agreement) to hold as, Pledged Equity and shall, if received by Pledgor, be received in trust for the benefit of Pledgee, be segregated from the other property or funds of Pledgor, and be forthwith delivered to Pledgee in the exact form received with any necessary indorsement or appropriate stock powers duly executed in blank, to be held by Pledgee as Collateral.

(b) If an Event of Default shall have occurred and be continuing, subject to the terms of the Intercreditor Agreement:

(i) all rights of Pledgor to receive and retain the dividends, distributions and interest payments which Pledgor would otherwise be authorized to receive and retain pursuant to subsection (a) of this Section 4.7 shall automatically cease, and all such rights shall thereupon become vested in Pledgee which shall thereupon have the right to receive and hold as Pledged Equity such dividends, distributions and interest payments;

10

Execution Version

(ii) without limiting the generality of the foregoing, concurrently with notice to the Pledgor of its intent to exercise such rights, any or all of the Pledged Equity shall be registered in the name of the Pledgee or its nominee, and the Pledgee or its nominee may thereafter exercise (x) all voting, corporate and other rights pertaining to such Pledged Equity at any meeting of shareholders of the JV Company or otherwise and (y) any and all rights of conversion, exchange and subscription and any other rights, privileges or options pertaining to such Pledged Equity, as if it were the absolute owner thereof (including, without limitation, the right to exchange at its discretion any and all of the Pledged Equity upon the merger, consolidation, reorganization, recapitalization or other fundamental change in the corporate or other organizational structure of the JV Company, or upon the exercise by the Pledgor or the Pledgee of any right, privilege or option pertaining to such Pledged Equity, and in connection therewith, the right to deposit and deliver any and all of the Pledged Equity with any committee, depositary, transfer agent, registrar or other designated agency upon such terms and conditions as the Pledgee may determine), all without liability except to account for property actually received by it, but the Pledgee shall have no duty to the Pledgor to exercise any such right, privilege or option and shall not be responsible for any failure to do so or delay in so doing; and

(iii) all dividends and interest payments which are received by Pledgor contrary to the provisions of subsection (b)(i) of this Section 4.7 shall be received in trust for the benefit of Pledgee, shall be segregated from other funds of Pledgor, and shall be forthwith paid over to Pledgee as Pledged Equity in the exact form received, to be held by Pledgee as Collateral.

Section 4.8 Registration Rights; Private Sale of Pledged Equity; Notice.

(a) If the Pledgee shall determine to exercise its right to sell any or all of the Pledged Equity pursuant to this Agreement, and if in the opinion of the Pledgee it is necessary or advisable to have the Pledged Equity, or that portion thereof to be sold, registered under the provisions of the Securities Act, Pledgor will cause the JV Company to (i) execute and deliver, and cause its directors and officers 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 Pledgee, necessary or advisable to register the Pledged Equity, 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 Equity, 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 Pledgee, are necessary or advisable, all in conformity with the requirements of the Securities Act and the rules and regulations of the Securities and Exchange Commission applicable thereto. The Pledgor agrees to cause the JV Company to comply with the provisions of the securities or “Blue Sky” laws of any and all jurisdictions which the Pledgee 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) Pledgor recognizes that Pledgee may deem it impracticable to effect a public sale of all or any part of the Pledged Equity and that Pledgee may, therefore, determine to

make one or more private sales of any such securities to a restricted group of purchasers who will be obligated 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. Pledgor acknowledges that any such private sale may be at prices and on terms less favorable to the seller than the prices and other terms which might have been obtained at a public sale and, notwithstanding the foregoing, agrees that such private sales shall be deemed to have been made in a commercially reasonable manner and that Pledgee shall have no obligation to delay the sale of any such securities for the period of time necessary to permit Pledgor or the JV Company to register such securities (with no obligation of either Pledgor or any Subsidiary to accomplish such registration) for public sale under the Securities Act.

(c) To the extent permitted under applicable law, the Pledgor hereby waives notice of the time and place of any public sale or the time after which any private sale or other disposition of all or any part of the Collateral may be made. If any notice of a proposed sale or other disposition of Collateral shall be required by law, which is not waived hereunder, such notice shall be deemed reasonable and proper in every case if given at least ten (10) days prior (or such shorter period as may be commercially reasonable) to (i) the date of any such public sale or (ii) the time after which any such private sale or other disposition may be made.

Section 4.9 Limitation on Rights and Waivers. All rights, powers and remedies herein conferred shall be exercisable by Pledgee only to the extent not prohibited by applicable law; and all waivers and relinquishments of rights and similar matters shall only be effective to the extent such waivers or relinquishments are not prohibited by applicable law.

Section 5.2 Amendments. None of the terms or provisions of this Agreement may be waived, amended, supplemented or otherwise modified except in accordance with Section 10.1 of the Credit Agreement.

Section 5.3 Preservation of Rights. Neither the Pledgee nor any other Secured Party shall by any act (except by a written instrument pursuant to Section 5.2 hereof), 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 the Pledgee or any other 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 the Pledgee or any other 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 the Pledgee or such other Secured Party would otherwise have on any future occasion.

Neither this Agreement nor the exercise by Pledgee or any other Secured Party or the failure of Pledgee or any other Secured Party to exercise any right, power or remedy conferred herein or by law shall be construed as relieving any Other Liable Party from liability on the Obligations or any deficiency thereon. This Agreement shall continue irrespective of the fact that the liability of any Other Liable Party may have ceased or irrespective of the validity or enforceability of any other Loan Document to which Pledgor or any Other Liable Party may be a party, and notwithstanding the reorganization, death, incapacity or bankruptcy of any Other Liable Party, and notwithstanding the reorganization or bankruptcy or other event or proceeding affecting any Other Liable Party.

Pledgor acknowledges and agrees that a breach of any of the covenants contained in Sections 3.2, 3.3, 4.7 and 4.8 hereof will cause irreparable injury to the Pledgee and the other Secured Parties, that the Pledgee and the other Secured Parties have no adequate remedy at law in respect of such breaches and therefore agrees, without limiting the right of the Pledgee or the Secured Parties to seek and obtain specific performance of other obligations of Pledgor contained in this Agreement, that the covenants of the Pledgor contained in the Sections referred to in this Section 5.12 shall, to the extent permitted under applicable law, be specifically enforceable against the Pledgor.

(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.

Section 5.15 Reinstatement. This Agreement shall remain in full force and effect and continue to be effective should any petition be filed by or against the Pledgor for liquidation or reorganization, should the Pledgor become insolvent or make an assignment for the benefit of any creditor or creditors, should a receiver or trustee be appointed for all or any significant part of any the Pledgor’s assets, or any similar proceeding is initiated or undertaken and shall continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Obligations, or any part thereof, is, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee of the Obligations, whether as a “voidable preference,” “fraudulent conveyance,” or otherwise, all as though such payment or performance had not been made.
