Each Debtor, and any of its Affiliates, employees, agents and other Persons acting for or in concert with such Debtor shall, acting as trustee for the Secured Party, receive, as the sole and exclusive property of the Secured Party, any moneys, checks, notes, drafts or other payments relating to and/or proceeds of Accounts or other Collateral which come into the possession or under the control of such Debtor or any Affiliates, employees, agent or other Persons acting for or in concert with such Debtor, and immediately upon receipt thereof, such Debtor or Persons shall deposit the same or cause the same to be deposited in kind, in a Blocked Account.

4.6 Events of Default, Etc. During the period during which an Event of Default shall have occurred and be continuing:

(a) each Debtor shall, at the request of the Secured Party or its Representative, assemble the Collateral (other than gas production, which shall be available for turnover in place at the wellhead or pipeline) and make it available to Secured Party or its Representative at a place or places designated by the Secured Party or its Representative which are reasonably convenient to Secured Party or its Representative, as applicable, and such Debtor;

(b) the Secured Party or its Representative may make any reasonable compromise or settlement deemed desirable with respect to any of the Collateral and may extend the time of payment, arrange for payment in installments, or otherwise modify the terms of, any of the Collateral;

(c) the Secured Party shall have all of the rights and remedies with respect to the Collateral of a secured party under the UCC (whether or not said UCC is in effect in the jurisdiction where the rights and remedies are asserted) and such additional rights and remedies to which a secured party is entitled under the laws in effect in any jurisdiction where any rights and remedies hereunder may be asserted, including, without limitation, the right, to the maximum extent permitted by law, to: (i) exercise all voting, consensual and other powers of ownership pertaining to the Collateral as if the Secured Party were the sole and absolute owner thereof (and each Debtor agrees to take all such action as may be appropriate to give effect to such right) and (ii) to the appointment of a receiver or receivers for all or any part of the Collateral or business of a Debtor, whether such receivership be incident to a proposed sale or sales of such Collateral or otherwise and without regard to the value of the Collateral or the solvency of any person or persons liable for the payment of the Liabilities secured by such Collateral. Each Debtor hereby consents to the appointment of such receiver or receivers, waives any and all defenses to such appointment and agrees that such appointment shall in no manner impair, prejudice or otherwise affect the rights of Secured Party under this Agreement. Each Debtor hereby expressly waives notice of a hearing for appointment of a receiver and the necessity for bond or an accounting by the receiver;

(d) the Secured Party or its Representative in their discretion may, in the name of the Secured Party or in the name of a Debtor or otherwise, demand, xxx for, collect or receive any money or property at any time payable or receivable on account of or in exchange for any of the Collateral, but shall be under no obligation to do so;

(e) the Secured Party or its Representative may take immediate possession and occupancy of any premises owned, used or leased by a Debtor and exercise all other rights and remedies which may be available to the Secured Party;

(f) the Secured Party may, upon ten (10) Business Days’ prior written notice to Debtors of the time and place (which notice Debtors hereby agree is commercially reasonable notification for purposes hereof), with respect to the Collateral or any part thereof which shall then be or shall thereafter come into the possession, custody or control of the Secured Party or its Representative, sell, lease, license, assign or otherwise dispose of all or any part of such Collateral, at such place or places as the Secured Party deems best, and for cash or for credit or for future delivery (without thereby assuming any credit risk), at public or private sale, without demand of performance or notice of intention to effect any such disposition or of the time or place thereof (except such notice as is required above or by applicable statute and cannot be waived), and the Secured Party or anyone else may be the purchaser, lessee, licensee, assignee or recipient of any or all of the Collateral so disposed of at any public sale (or, to the extent permitted by law, at any private sale) and thereafter hold the same absolutely, free from any claim or right of whatsoever kind, including any right or equity of redemption (statutory or otherwise), of Debtors, any such demand, notice and right or equity being hereby expressly waived and released. The Secured Party may, without notice or publication, adjourn any public or private sale or cause the same to be adjourned from time to time by announcement at the time and place fixed for the sale, and such sale may be made at any time or place to which the sale may be so adjourned;

(g) the rights, remedies and powers conferred by this Section 4.6 are in addition to, and not in substitution for, any other rights, remedies or powers that the Secured Party may have under any Transaction Document, at law, in equity or by or under the UCC or any other statute or agreement. The Secured Party may proceed by way of any action, suit or other proceeding at law or in equity and no right, remedy or power of the Secured Party will be exclusive of or dependent on any other. The Secured Party may exercise any of its rights, remedies or powers separately or in combination and at any time.

The proceeds of each collection, sale or other disposition under this Section 4.6 shall be applied in accordance with Section 4.9 hereof.

4.7 Deficiency. If the proceeds of sale, collection or other realization of or upon the Collateral are insufficient to cover the costs and expenses of such realization and the payment in full of the Liabilities, Debtors shall remain liable for any deficiency.

4.8 Private Sale. Each Debtor recognizes that the Secured Party may be unable to effect a public sale of any or all of the Collateral consisting of securities by reason of certain prohibitions contained in the Securities Act of 1933, as amended (the “Act”), and applicable state securities laws, but may be compelled to resort to one or more private sales thereof to a restricted group of purchasers who will be obliged to agree, among other things, to acquire such Collateral for their own account for investment and not with a view to the distribution or resale thereof. Each Debtor acknowledges and agrees that any such private sale may result in prices and other terms less favorable to the seller 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 Secured Party shall be under no obligation to delay a sale of any of the Collateral to permit a Debtor to register such Collateral for public sale under the Act, or under applicable state securities laws, even if Debtors would agree to do so. The Secured Party shall not incur any liability as a result of the sale of any such Collateral, or any part thereof, at any private sale provided for in this Agreement conducted in a commercially reasonable manner, and each Debtor hereby waives any claims against the Secured Party arising by reason of the fact that the price at which the Collateral may have been sold at such a private sale was less than the price which might have been obtained at a public sale or was less than the aggregate amount of the Liabilities, even if the Secured Party accepts the first offer received and does not offer the Collateral to more than one offeree.

Each Debtor further agrees to do or cause to be done all such other acts and things as may be necessary to make such sale or sales of any portion or all of any such Collateral valid and binding and in compliance with any and all applicable laws, regulations, orders, writs, injunctions, decrees or awards of any and all courts, arbitrators or governmental instrumentalities, domestic or foreign, having jurisdiction over any such sale or sales, all at such Debtor’s expense, provided that Debtors shall be under no obligation to take any action to enable any or all of such Collateral to be registered under the provisions of the Act. Each Debtor further agrees that a breach of any of the covenants contained in this Section 4.8 will cause irreparable injury to the Secured Party, that the Secured Party has no adequate remedy at law in respect of such breach and, as a consequence, agrees that each and every covenant contained in this Section 4.8 shall be specifically enforceable against Debtors, and each Debtor 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.

4.9 Application of Proceeds. The proceeds of any collection, sale or other realization of all or any part of the Collateral, and any other cash at the time held by the Secured Party under this Agreement, shall be applied in the manner set forth in the Notes (or, if not so set forth, in a manner acceptable to, and at the election of, the Secured Party).

4.10 Attorney-in-Fact. Each Debtor hereby irrevocably constitutes and appoints the Secured Party, 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 Debtor and in the name of such Debtor or in its own name, from time to time in the discretion of the Secured Party, for the purpose of carrying out the terms of this Agreement, to take any and all appropriate action and to execute and deliver any and all documents and instruments which may be necessary or desirable to perfect or protect any security interest granted hereunder or to maintain the perfection or priority of any security interest granted hereunder, and, without limiting the generality of the foregoing, hereby gives the Secured Party the power and right, on behalf of such Debtor, without notice to or assent by such Debtor (to the extent permitted by applicable law), to do the following upon the occurrence and during the continuation of any Event of Default:

(a) to take any and all appropriate action and to execute and deliver any and all documents and instruments which may be necessary or desirable to accomplish the purposes of this Agreement;

(b) to ask, demand, collect, receive and give acquittance and receipts for any and all moneys due and to become due under any Collateral and, in the name of such Debtor or its own name or otherwise, to take possession of and endorse and collect any checks, drafts, notes, acceptances or other Instruments for the payment of moneys due under any Collateral and to file any claim or to take any other action or proceeding in any court of law or equity or otherwise deemed appropriate by the Secured Party for the purpose of collecting any and all such moneys due under any Collateral whenever payable and to file any claim or to take any other action or proceeding in any court of law or equity or otherwise deemed appropriate by the Secured Party for the purpose of collecting any and all such moneys due under any Collateral whenever payable;

(c) to pay or discharge charges or liens levied or placed on or threatened against the Collateral, to effect any insurance called for by the terms of this Agreement and to pay all or any part of the premiums therefor;

(d) to direct any party liable for any payment under any of the Collateral to make payment of any and all moneys due, and to become due thereunder, directly to the Secured Party or as the Secured Party shall direct, and to receive payment of and receipt for any and all moneys, claims and other amounts due, and to become due at any time, in respect of or arising out of any Collateral;

(e) to sign and indorse any invoices, freight or express bills, bills of lading, storage or warehouse receipts, drafts against debtors, assignments, verifications and notices in connection with accounts and other Documents constituting or relating to the Collateral;

(f) to 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 part thereof and to enforce any other right in respect of any Collateral;

(g) to defend any suit, action or proceeding brought against a Debtor with respect to any Collateral;

(h) to settle, compromise or adjust any suit, action or proceeding described above and, in connection therewith, to give such discharges or releases as the Secured Party may deem appropriate;

(i) to the extent that a Debtor’s authorization given in Section 4.1(b) of this Agreement is not sufficient to file such financing statements with respect to this Agreement, with or without such Debtor’s signature, or to file a photocopy of this Agreement in substitution for a financing statement, as the Secured Party may deem appropriate and to execute in such Debtor’s name such financing statements and amendments thereto and continuation statements which may require such Debtor’s signature; and

(j) generally to sell, transfer, pledge, make any agreement with respect to or otherwise deal with any of the Collateral as fully and completely as though the Secured Party were the absolute owners thereof for all purposes, and to do, at the Secured Party’s option and at such Debtor’s expense, at any time, or from time to time, all acts and things which the Secured Party reasonably deems necessary to protect, preserve or realize upon the Collateral and the Secured Party’s lien therein, in order to effect the intent of this Agreement, all as fully and effectively as such Debtor might do.

Each Debtor hereby ratifies, to the extent permitted by law, all that such attorneys lawfully do or cause to be done by virtue hereof. The power of attorney granted hereunder is a power coupled with an interest and shall be irrevocable until the Liabilities are indefeasibly paid in full in cash and this Agreement is terminated in accordance with Section 4.12 hereof.

Each Debtor also authorizes the Secured Party, at any time from and after the occurrence and during the continuation of any Event of Default, (x) to communicate in its own name with any party to any Contract with regard to the assignment of the right, title and interest of such Debtor in and under the Contracts hereunder and other matters relating thereto and (y) to execute, in connection with any sale of Collateral provided for in Section 4.6 hereof, any endorsements, assignments or other instruments of conveyance or transfer with respect to the Collateral.

4.11 Perfection. Prior to or concurrently with the execution and delivery of this Agreement, each Debtor shall:

(a) file such financing statements, assignments for security and other documents in such offices as may be necessary or as the Secured Party or the Representative may request to perfect the security interests granted by Section 3 of this Agreement; and

(b) at Secured Party’s request, deliver to the Secured Party or its Representative the originals of all Instruments together with, in the case of Instruments constituting promissory notes, allonges attached thereto showing such promissory notes to be payable to the order of a blank payee.

(c) deliver to the Secured Party or its Representative the originals of all Motor Vehicle Titles (other than, until the payment in full in cash of the FNBW Note, the Motor Vehicles Titles of the FNBW Vehicles), duly endorsed indicating the Secured Party’s interest therein as a lienholder, together with such other documents as may be required consistent with Section 4.1(d) hereof to perfect the security interest granted by Section 3 in all such Motor Vehicles.

4.12 Termination. This Agreement and the Liens and security interests granted hereunder shall not terminate until the termination of the Notes and the full and complete performance and indefeasible satisfaction of all the Liabilities (i) in respect of the Notes (including, without limitation, the indefeasible payment in full in cash of all such Liabilities) and (ii) with respect to which claims have been asserted by Collateral Agent and/or Buyers, whereupon the Secured Party shall forthwith cause to be assigned, transferred and delivered, against receipt but without any recourse, warranty or representation whatsoever, any remaining Collateral to or on the order of Debtors. The Secured Party shall also execute and deliver to Debtors upon such termination and at Debtors’ expense such UCC termination statements, certificates for terminating the liens on the Motor Vehicles (if any) and such other documentation as shall be reasonably requested by Debtors to effect the termination and release of the Liens and security interests in favor of the Secured Party affecting the Collateral.

4.13 Further Assurances. At any time and from time to time, upon the written request of the Secured Party or its Representative, and at the sole expense of Debtors, Debtors will promptly and duly execute and deliver any and all such further instruments, documents and agreements and take such further actions as the Secured Party or its Representative may reasonably require in order for the Secured Party to obtain the full benefits of this Agreement and of the rights and powers herein granted in favor of the Secured Party, including, without limitation, using Debtors’ best efforts to secure all consents and approvals necessary or appropriate for the assignment to the Secured Party of any Collateral held by Debtors or in which a Debtor has any rights not heretofore assigned, the filing of any financing or continuation statements under the UCC with respect to the liens and security interests granted hereby, transferring Collateral to the Secured Party’s possession (if a security interest in such Collateral can be perfected by possession), placing the interest of the Secured Party as lienholder on the certificate of title of any Motor Vehicle (other than, until the payment in full in cash of the FNBW Note, the FNBW Vehicles) and obtaining waivers of liens from landlords and mortgagees. Each Debtor also hereby authorizes the Secured Party and its Representative to file any such financing or continuation statement without the signature of such Debtor to the extent permitted by applicable law.

4.14 Limitation on Duty of Secured Party. The powers conferred on the Secured Party under this Agreement are solely to protect the Secured Party’s interest on behalf of itself and Buyers in the Collateral and shall not impose any duty upon it to exercise any such powers. The Secured Party shall be accountable only for amounts that it actually receives as a result of the exercise of such powers and neither the Secured Party nor its Representative nor any of their respective officers, directors, employees or agents shall be responsible to Debtors for any act or failure to act, except for willful misconduct. Without limiting the foregoing, the Secured Party and any Representative shall be deemed to have exercised reasonable care in the custody and preservation of the Collateral in their possession if such Collateral is accorded treatment substantially equivalent to that which the relevant Secured Party or any Representative, in its individual capacity, accords its own property consisting of the type of Collateral involved, it being understood and agreed that neither the Secured Party nor any Representative shall have any responsibility for taking any necessary steps (other than steps taken in accordance with the standard of care set forth above) to preserve rights against any Person with respect to any Collateral.

Also without limiting the generality of the foregoing, neither the Secured Party nor any Representative shall have any obligation or liability under any Contract or license by reason of or arising out of this Agreement or the granting to the Secured Party of a security interest therein or assignment thereof or the receipt by the Secured Party or any Representative of any payment relating to any Contract or license pursuant hereto, nor shall the Secured Party or any Representative be required or obligated in any manner to perform or fulfill any of the obligations of Debtors under or pursuant to any Contract or license, or to make any payment, or to make any inquiry as to the nature or the sufficiency of any payment received by it or the sufficiency of any performance by any party under any Contract or license, or to present or file any claim, or to take any action to collect or enforce any performance or the payment of any amounts which may have been assigned to it or to which it may be entitled at any time or times.

Section 5. Miscellaneous.

5.1 No Waiver. No failure on the part of the Secured Party or any of its Representatives to exercise, and no course of dealing with respect to, and no delay in exercising, any right, power or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise by the Secured Party or any of its Representatives of any right, power or remedy hereunder preclude any other or further exercise thereof or the exercise of any other right, power or remedy. The rights and remedies hereunder provided are cumulative and may be exercised singly or concurrently, and are not exclusive of any rights and remedies provided by law.

5.2 Governing Law. All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be governed by the internal laws of the State of New York, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of New York or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of New York.

Secured Party, in its capacity as collateral agent, may assign its rights hereunder without the consent of Debtors, in which event such assignee shall be deemed to be Secured Party hereunder with respect to such assigned rights.

5.6 Counterparts; Headings. This Agreement may be authenticated in any number of counterparts, all of which taken together shall constitute one and the same instrument and any of the parties hereto may authenticate this Agreement by signing any such counterpart.

The headings in this Agreement are for convenience of reference only and shall not alter or otherwise affect the meaning hereof.

5.7 Severability.

NOTHING HEREIN SHALL LIMIT THE RIGHT OF SECURED PARTY TO BRING PROCEEDINGS AGAINST ANY DEBTOR IN THE COURTS OF ANY OTHER JURISDICTION. ANY JUDICIAL PROCEEDING BY A DEBTOR AGAINST SECURED PARTY, ANY BUYER OR ANY AFFILIATE THEREOF INVOLVING, DIRECTLY OR INDIRECTLY, ANY MATTER IN ANY WAY ARISING OUT OF, RELATED TO, OR CONNECTION WITH THIS AGREEMENT SHALL BE BROUGHT ONLY IN A COURT IN NEW YORK, NEW YORK (AND SECURED PARTY AND BUYERS HEREBY SUBMIT TO THE JURISDICTION OF SUCH COURT). EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES PERSONAL SERVICE OF PROCESS AND CONSENTS TO PROCESS BEING SERVED IN ANY SUCH ACTION OR PROCEEDING BY MAILING A COPY THEREOF TO SUCH PARTY AT THE ADDRESS FOR NOTICES TO IT IN ACCORDANCE WITH SECTION 5.3 OF THIS AGREEMENT AND AGREES THAT SUCH NOTICE SHALL CONSTITUTE GOOD AND SUFFICIENT SERVICE OF PROCESS AND NOTICE THEREOF. NOTHING CONTAINED HEREIN SHALL BE DEEMED TO LIMIT IN ANY WAY ANY RIGHT TO SERVE PROCESS IN ANY MANNER PERMITTED BY LAW.

5.9 WAIVER OF RIGHT TO TRIAL BY JURY. EACH DEBTOR AND SECURED PARTY EACH WAIVE THEIR RESPECTIVE RIGHTS TO A TRIAL BY JURY OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY, IN ANY ACTION, PROCEEDING OR OTHER LITIGATION OF ANY TYPE BROUGHT BY ANY OF THE PARTIES AGAINST ANY OTHER PARTY OR PARTIES, WHETHER WITH RESPECT TO CONTRACT CLAIMS, TORT CLAIMS, OR OTHERWISE. EACH DEBTOR AND SECURED PARTY EACH AGREE THAT ANY SUCH CLAIM OR CAUSE OF ACTION SHALL BE TRIED BY A COURT TRIAL WITHOUT A JURY. WITHOUT LIMITING THE FOREGOING, THE PARTIES FURTHER AGREE THAT THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY IS WAIVED BY OPERATION OF THIS SECTION 5.9 AS TO ANY ACTION, COUNTERCLAIM OR OTHER PROCEEDING WHICH SEEKS, IN WHOLE OR IN PART, TO CHALLENGE THE VALIDITY OR ENFORCEABILITY OF THIS AGREEMENT OR ANY PROVISION HEREOF. THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT.

5.10 Joint and Several. The obligations, covenants and agreements of Debtors hereunder shall be the joint and several obligations, covenants and agreements of each Debtor, whether or not specifically stated herein without preferences or distinction among them.

5.11 Collateral Agent and Buyer Indemnification.

(a) Each Buyer hereby irrevocably appoints and authorizes the Secured Party to act as collateral agent (the “Collateral Agent”) on its behalf under this Agreement and to enter into each of the instruments, documents and agreements, including any pledge agreement, guaranty, financing statements, mortgage, Account Control Agreement or any other Security Documents (the “Financing Documents”), to which Secured Party is a party (including in its capacity as Collateral Agent) on such Buyer’s behalf and to take such actions as Collateral Agent on such Buyer’s behalf and to exercise such powers under the Financing Documents as are delegated to Collateral Agent or Secured Party (as applicable) by the terms thereof, together with all such powers as are reasonably incidental thereto. The Collateral Agent shall take such action under this Agreement and/or any other Transaction Documents as the Collateral Agent shall reasonably be directed by the Requisite Buyers in accordance with the terms of the Transaction Documents. Secured Party is authorized and empowered to amend, modify, or waive any provisions of this Agreement or the other Financing Documents only with the consent of the Requisite Buyers.

(b) Whether or not the transactions contemplated hereby shall be consummated, upon demand therefor Buyers shall indemnify the Collateral Agent (to the extent not reimbursed by or on behalf of the Company and without limiting the obligation of the Company to do so), ratably from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses and disbursements of any kind whatsoever, including, for purposes of clarification, all Taxes, which may at any time (including at any time following the payment in full of the Notes and the termination or resignation of the Collateral Agent) be imposed on, incurred by or asserted against the Collateral Agent in any way relating to or arising out of this Agreement, any other Financing Document or any document contemplated hereby or referred to herein or the transactions contemplated hereby or thereby or any action taken or omitted by the Collateral Agent under or in connection with any of the foregoing; provided, however, that no Buyer shall not be liable for the payment to the Collateral Agent of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting solely from the Collateral Agent’s gross negligence or willful misconduct. In addition, each Buyer shall reimburse the Collateral Agent upon demand for its ratable share of any costs or out-of-pocket expenses (including attorney costs) incurred by the Collateral Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement, any other Transaction Document, or any document contemplated hereby or referred to herein to the extent that the Collateral Agent is not reimbursed for such expenses by or on behalf of the Company. Without limiting the generality of the foregoing, if any Governmental Authority of any jurisdiction asserts a claim that the Collateral Agent did not properly withhold tax from amounts paid to or for the account of any Buyer (because the appropriate form was not delivered, was not properly executed, or because such Buyer failed to notify the Collateral Agent of a change in circumstances which rendered the exemption from, or reduction of, withholding tax ineffective, or for any other reason) such Buyer shall indemnify the Collateral Agent fully for all amounts paid, directly or indirectly, by the Collateral Agent as tax or otherwise, including penalties and interest, and including any taxes imposed by any jurisdiction on the amounts payable to the Collateral Agent under this Section 5.11(b), together with all related costs and expenses (including attorney costs). The obligation of Buyers in this Section 5.11(b) shall survive the payment of all Liabilities hereunder.

(c) The Collateral Agent shall not be deemed to have knowledge or notice of the occurrence of any Event of Default or any event that with the giving of notice or passage of time would constitute an Event of Default unless the Collateral Agent shall have received written notice from a Buyer describing such Event of Default or event that with the giving of notice or passage of time would constitute an Event of Default and stating that such notice is a “notice of default”. Upon the occurrence and continuance of an Event of Default, or an event that with the giving of notice or passage of time would constitute an Event of Default, the Collateral Agent shall take such action under this Agreement and/or any other Transaction Documents with respect to such Event of Default or event that with the giving of notice or passage of time would constitute an Event of Default as Collateral Agent shall reasonably be directed by the Requisite Buyers in accordance with the terms of the Transaction Documents, provided that unless and until the Collateral Agent shall have received such directions, the Collateral Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect of such Event of Default or event that with the giving of notice or passage of time would constitute an Event of Default or as the Collateral Agent shall deem advisable in the best interests of Buyers. In taking such action or refraining from taking such action without specific direction from the Requisite Buyers, the Collateral Agent shall use the same degree of care and skill as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs.

(d) Nothing in this Section 5.11 shall be deemed to limit or otherwise affect the rights of Secured Party or Buyers to exercise any remedy provided in this Agreement or any other Transaction Document.

(e) The Collateral Agent may resign from the performance of all of its functions and duties hereunder and/or under the other Financing Documents at any time by giving thirty (30) Business Days prior written notice to Buyers. Such resignation shall take effect upon the appointment of a successor Collateral Agent pursuant to clause (f) below or as otherwise provided below.

(f) Upon (i) Buyers’ receipt of a notice of resignation by the Collateral Agent in accordance with clause (e) above, or (ii) written notice by the Requisite Buyers to Collateral Agent of the Requisite Buyers’ election to remove the existing Collateral Agent and appoint a successor Collateral Agent, the Requisite Buyers shall have the right to appoint a successor Collateral Agent. Upon the acceptance of a successor's appointment as Collateral Agent hereunder and notice of such acceptance to the retiring Collateral Agent, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring (or retired) Collateral Agent, the retiring Collateral Agent's resignation shall become immediately effective and the retiring Collateral Agent shall be discharged from all of its duties and obligations hereunder and under the other Financing Documents (if such resignation was not already effective and such duties and obligations not already discharged, as provided below in this paragraph). If no such successor shall have been so appointed by the Requisite Buyers and shall have accepted such appointment within thirty (30) days after the retiring Collateral Agent gives notice of its resignation or the Requisite Buyers give notice of their election to replace the retiring Collateral Agent, then the retiring Collateral Agent may, on behalf of Buyers (but without any obligation) appoint a successor Collateral Agent without the consent of any Buyer. From and following the expiration of such thirty (30) day period, Collateral Agent shall have the exclusive right without any Person's consent, upon one (1) Business Days' notice to Buyers, to make its resignation or removal effective immediately. From and following the effectiveness of such notice, (i) the retiring Collateral Agent shall be discharged from its duties and obligations hereunder and under the other Financing Documents and (ii) all actions, payments, communications and determinations provided to be made by, to or through Collateral Agent shall instead be made by or to each Buyer directly, until such time as the Requisite Buyers appoint a Collateral Agent as provided for above in this paragraph. The provisions of this Agreement shall continue in effect for the benefit of any retiring Collateral Agent and its sub-agents after the effectiveness of its resignation or removal hereunder and under the other Financing Documents in respect of any actions taken or omitted to be taken by any of them while the retiring Collateral Agent was acting or was continuing to act as Collateral Agent.

5.12 No Strict Construction. The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any party.

5.13 ENTIRE AGREEMENT; AMENDMENT. THIS AGREEMENT, TOGETHER WITH THE OTHER TRANSACTION DOCUMENTS, SUPERSEDES ALL OTHER PRIOR ORAL OR WRITTEN AGREEMENTS BETWEEN SECURED PARTY, THE OBLIGORS, THEIR AFFILIATES AND PERSONS ACTING ON THEIR BEHALF WITH RESPECT TO THE MATTERS DISCUSSED HEREIN, AND THIS AGREEMENT, TOGETHER WITH THE OTHER TRANSACTION DOCUMENTS AND THE OTHER INSTRUMENTS REFERENCED HEREIN AND THEREIN, CONTAIN THE ENTIRE UNDERSTANDING OF THE PARTIES WITH RESPECT TO THE MATTERS COVERED HEREIN AND THEREIN AND, EXCEPT AS SPECIFICALLY SET FORTH HEREIN OR THEREIN, NEITHER THE SECURED PARTY NOR ANY OBLIGOR MAKES ANY REPRESENTATION, WARRANTY, COVENANT OR UNDERTAKING WITH RESPECT TO SUCH MATTERS. AS OF THE DATE OF THIS AGREEMENT, THERE ARE NO UNWRITTEN AGREEMENT BETWEEN THE PARTIES WITH RESPECT TO THE MATTERS DISCUSSED HEREIN. NO PROVISION OF THIS AGREEMENT MAY BE AMENDED, MODIFIED OR SUPPLEMENTED OTHER THAN BY AN INSTRUMENT IN WRITING SIGNED BY THE OBLIGORS AND THE SECURED PARTY.
