Each Partnership/Limited Liability Company issuing a Partnership/Limited Liability Company Interest, is duly organized, currently existing, and in good standing in the jurisdiction of its formation; except in connection with the Restructure Transactions, there have been no material amendments, modifications, or supplements to any agreement or certificate creating any Partnership/Limited Liability Company or any material contract relating to the Partnerships/Limited Liability Companies, of which Secured Party has not been advised in writing; no event of default, default, breach, or potential default has occurred and is continuing under any Partnership/Limited Liability Company Agreement, except for such defaults or breaches that would result from the Restructure Transactions or would not reasonably be expected to result in a Material Adverse Effect; and no approval or consent of the partners of any Partnership/Limited Liability Company is required as a

Multiparty Borrowing Base
Credit Facility Pledge & Security Agreement

condition to the validity and enforceability of the Security Interest created hereby or the consummation of the transactions contemplated hereby which has not been duly obtained by the relevant Debtor. Each Debtor has good title to its Partnership/Limited Liability Company Interests free and clear of all Liens and encumbrances (except for the Security Interest granted hereby or under the Intercreditor Agreement or Permitted Liens). The Partnership/Limited Liability Company Interests are validly issued, fully paid, and nonassessable (except to the extent required by applicable Law) and are not subject to statutory, contractual, or other restrictions governing their transfer, ownership, or control, except as set forth in the applicable Partnership/Limited Liability Company Agreements or applicable securities Laws or Permitted Liens. All capital contributions required to be made by the terms of the Partnership/Limited Liability Company Agreements for each Partnership/Limited Liability Company as of the date hereof have been made. No Partnership/Limited Liability Company interests owned by a Debtor are evidenced by certificates.

(1) Accounts. All Collateral that is accounts, contract rights, chattel paper, instruments, payment intangibles, or general intangibles is free from any claim for credit, deduction, or allowance of an Obligor, from any defense, condition, dispute, setoff, or counterclaim (collectively “Deductions”), and there is no extension or indulgence with respect thereto, except to the extent such Deductions, extensions and indulgences could not reasonably be expected to have a Material Adverse Effect.

(m) Deposit Accounts. With respect to the Deposit Accounts, (i) each Debtor maintains its Deposit Account with the banks listed on Annex B-1 hereto, (ii) upon request by the Secured Party, each Debtor shall use its reasonable efforts to, within thirty (30) days of such request, cause each such bank to acknowledge to Secured Party that each such Deposit Account is subject to the Security Interest and Liens herein created, that the pledge of such Deposit Account has been recorded in the books and records of such bank, and that Secured Party shall have “control” (as defined in the UCC) over such Deposit Account, and (iii) each Debtor has the legal Right to pledge and assign to Secured Party the funds deposited and to be deposited in each such Deposit Account.

(n) Intellectual Property.

(i) All of the Intellectual Property is subsisting, valid, and enforceable (except where any failure to be subsisting, valid and enforceable would not reasonably be expected to have a Material Adverse Effect). The information contained on Annex B-2 hereto is true, correct and complete. All issued Patents, Patent applications, registered Trademarks, Trademark applications, registered Copyrights, and Copyright applications of each Debtor are identified on Annex B-2 hereto.

(ii) Except for off-the-shelf software and other Intellectual Property of which a Debtor is licensee (as to which this representation is inapplicable), each Debtor is the sole and exclusive owner of, the entire and unencumbered Right, title, and interest in and to its owned Intellectual Property free and clear of any Liens including, without limitation, any pledges, assignments, licenses, user agreements, and covenants by such Debtor not to xxx third Persons, other than Permitted Liens or licenses permitted by Paragraph 8(c).

Multiparty Borrowing Base
Credit Facility Pledge & Security Agreement

(iii) As of the date hereof, to each Debtor’s knowledge, no third party is infringing any of such Debtor’s Rights under its Intellectual Property.

(iv) Each Debtor has performed and will continue to perform all acts and has paid and will continue to pay all required fees and Taxes to maintain each material item of the Intellectual Property in full force and effect throughout the world, as applicable.

(vi) As of the date hereof, to each Debtor’s knowledge, no claims with respect to its Intellectual Property have been asserted and are pending (i) to the effect that the sale, licensing, pledge, or use of any of the products of such Debtor’s business infringes any other party’s valid copyright, trademark, service xxxx, trade secret, or other intellectual property Right, (ii) against the use by such Debtor of any Intellectual Property used in such Debtor’s business as currently conducted, or (iii) challenging the ownership or use by such Debtor of any of the Intellectual Property that such Debtor purports to own or use.

The foregoing representations and warranties will be true and correct in all material respects with respect to any additional Collateral or additional specific descriptions of certain Collateral delivered to Secured Party in the future by a Debtor. The failure of any of these representations or warranties or any description of Collateral therein to be accurate or complete shall not impair the Security Interest in any such Collateral.

6. COVENANTS. So long as any Borrowing Base Facility Lenders are committed to make Credit Extensions under the Borrowing Base Facility Credit Agreement, and until the Obligations are paid and performed in full (except as provided in Sections 10.01(d) and 10.01(e) of the Borrowing Base Facility Credit Agreement), each Debtor covenants and agrees with Secured Party that such Debtor will:

(a) Borrowing Base Facility Credit Agreement. (i) Comply with, perform, and be bound by all applicable covenants and agreements in the Borrowing Base Facility Credit Agreement, each of which is hereby ratified and confirmed.

(b) Books and Records Concerning Collateral; Inspection Rights. Each Debtor shall comply with the provisions of Section 6.09 and 6.10 of the Borrowing Base Facility Credit Agreement regarding records concerning and inspection rights relating to the Collateral. In addition, from time to time at the request of Secured Party deliver to Secured Party such information regarding such Debtor that is in the possession of Debtor as Secured Party may reasonably request.

(c) Annexes. Together with the delivery of compliance certificates pursuant to Section 6.02(a) of the Borrowing Base Facility Credit Agreement, update all annexes hereto if

Multiparty Borrowing Base
Credit Facility Pledge & Security Agreement

any information therein shall become inaccurate or incomplete and such updated Annexes shall replace the existing Annexes for all purposes of this Agreement. Notwithstanding any other provision herein, a Debtor’s failure to describe any Collateral required to be listed on any annex hereto shall not impair Secured Party’s Security Interest in the Collateral.

(d) Perform Obligations. Perform all of such Debtor’s duties under and in connection with each transaction to which the Collateral, or any material part thereof, relates, in the ordinary course of business except when in such Debtor’s business judgment non-performance is justified. Notwithstanding anything to the contrary contained herein, (i) such Debtor shall remain liable under the contracts, agreements, documents, and instruments included in the Collateral to the extent set forth therein to perform all of its duties and obligations thereunder to the same extent as if this Security Agreement had not been executed, (ii) the exercise by Secured Party of any of its Rights or remedies hereunder shall not release such Debtor from any of its duties or obligations under the contracts, agreements, documents, and instruments included in the Collateral, and (iii) Secured Party shall not have any indebtedness, liability, or obligation under any of the contracts, agreements, documents, and instruments included in the Collateral by reason of this Security Agreement, and Secured Party shall not be obligated to perform any of the obligations or duties of such Debtor thereunder or to take any action to collect or enforce any claim for payment assigned hereunder.

(e) Intentionally Deleted.

(f) Collateral in Trust. Hold in trust (and not commingle with other assets of such Debtor) for Secured Party all Collateral that is chattel paper, instruments, Collateral Notes, Pledged Securities, or Documents (as defined in Article 9 of the UCC) at any time received by such Debtor, and promptly deliver same to Secured Party, unless Secured Party at its option (which may be evidenced only by a writing signed by Secured Party stating that Secured Party elects to permit such Debtor to so retain) permits such Debtor to retain the same, but any chattel paper, instruments, Collateral Notes, Pledged Securities, or Documents (as defined in Article 9 of the UCC) and (to the extent required under paragraph (t) hereof) so retained shall be marked to state that they are assigned to Secured Party; each such instrument shall be endorsed to the order of Secured Party (but the failure of same to be so marked or endorsed shall not impair the Security Interest thereon).

(g) Control. Execute all documents and take any action required by Secured Party in order for Secured Party to obtain “control” (as defined in the UCC) with respect to Collateral consisting of Deposit Accounts, investment property, uncertificated Pledged Securities, and letter-of-credit rights. If a Debtor at any time holds or acquires an interest in any electronic chattel paper or any “transferable record,” as that term is defined in the federal Electronic Signatures in Global and National Commerce Act, or in the Uniform Electronic Transactions Act as in effect in any relevant jurisdiction, promptly notify Secured Party thereof and, at the request of Secured Party, take such action as Secured Party may reasonably request to vest in Secured Party control under the UCC of such electronic chattel paper or control under the federal Electronic Signatures in Global and National Commerce Act or, as the case may be, the Uniform Electronic Transactions Act, as so in effect in such jurisdiction, of such transferable record.

(h) Further Assurances. At such Debtor’s expense and Secured Party’s request, before or after a Default or Event of Default: (i) file or cause to be filed such applications and take such

Multiparty Borrowing Base
Credit Facility Pledge & Security Agreement

other actions as Secured Party may reasonably request to obtain the consent or approval of any Governmental Authority to Secured Party’s Rights hereunder including, without limitation, the Right to sell all the Collateral upon an Event of Default without additional consent or approval from such Governmental Authority (and, because such Debtor agrees that Secured Party’s remedies at Law for failure of such Debtor to comply with this provision would be inadequate and that such failure would not be adequately compensable in damages, such Debtor agrees that its covenants in this provision may be specifically enforced); (ii) from time to time promptly execute and deliver to Secured Party all such other assignments, certificates, supplemental documents, and financing statements, and do all other acts or things as Secured Party may reasonably request in order to more fully create, evidence, perfect, continue, and preserve the priority of the Security Interest and to carry out the provisions of this Security Agreement; and (iii) pay all filing fees in connection with any financing, continuation, or termination statement or other instrument with respect to the Security Interests.

(i) Encumbrances. Not create, permit, or suffer to exist, and shall defend the Collateral against, any Lien or other encumbrance on the Collateral, other than Permitted Liens, and shall defend such Debtor’s Rights in the Collateral and Secured Party’s Security Interest in the Collateral against the claims and demands of all Persons except those holding or claiming Permitted Liens. No Debtor shall do anything to impair the Rights of Secured Party in the Collateral.

(j) Estoppel and Other Agreements and Matters. Upon the reasonable request of Secured Party, either (i) use commercially reasonable efforts to cause the landlord or lessor for each location where any material inventory or equipment is maintained to execute and deliver to Secured Party an estoppel and subordination agreement in such form as may be reasonably acceptable to Secured Party and its counsel, or (ii) deliver to Secured Party a legal opinion or other evidence (in each case that is reasonably satisfactory to Secured Party and it counsel) that neither the applicable lease nor the Laws of the jurisdiction in which that location is situated provide for a contractual, common Law, or statutory landlord’s Lien that is senior to or pari passu with the Security Interest.

(k) Fixtures. For any Collateral that is a fixture or an accession which has been attached to real estate or other goods prior to the perfection of the Security Interest, use commercially reasonable efforts to furnish to Secured Party, upon reasonable demand, a disclaimer of interest in each such fixture or accession and a consent in writing to the Security Interest of Secured Party therein, signed by all Persons having any interest in such fixture or accession by virtue of any interest in the real estate or other goods to which such fixture or accession has been attached.

(l) Certificates of Title. Upon the request of Secured Party, if a certificate of title is issued or outstanding with respect to any Vehicle with a fair market value of at least $50,000, cause the Security Interest to be properly noted thereon.

(m) Warehouse Receipts Non-Negotiable. If any warehouse receipt or receipt in the nature of a warehouse receipt is issued in respect of any of the Collateral, agree that such warehouse receipt or receipt in the nature thereof shall not be “negotiable” (as such term is used in Section 7-104 of the UCC) unless such warehouse receipt or receipt in the nature thereof is delivered to Secured Party.

Multiparty Borrowing Base
Credit Facility Pledge & Security Agreement

(n) Impairment of Collateral. Not use any material portion of the Collateral, or permit the same to be used, for any unlawful purpose, in any manner that is reasonably likely to materially adversely impair the value or usefulness of the Collateral, or in any manner inconsistent with the provisions or requirements of any policy of insurance thereon nor affix or install any accessories, equipment, or device on the Collateral or on any component thereof if such addition will materially impair the original intended function or use of the Collateral or such component.

(o) Collateral Notes and Collateral Note Security. Without the prior written consent of Secured Party not (i) materially modify or substitute, or permit material modification or substitution of, any Collateral Note or any document evidencing the Collateral Note Security, if the effect thereof would be to materially adversely affect the value of the Collateral Notes and Collateral Note Security taken as a whole, or (ii) release any material portion of any Collateral Note Security unless paid in full or otherwise specifically required by the terms thereof, except in the exercise of such Debtor’s reasonable business judgment.

(p) Securities. Except as permitted by the Borrowing Base Facility Credit Agreement, not sell, exchange, or otherwise dispose of, any of the Pledged Securities; and take any action requested by Secured Party to allow Secured Party to fully enforce its Security Interest in the Pledged Securities including, without limitation, the filing of any claims with any court, liquidator, trustee, custodian, receiver, or other like person or party.

(q) Depository Bank. With respect to any Deposit Accounts, (i) maintain the Deposit Accounts at the banks (a “Depository Bank”) described on Annex B-1 or such additional depository banks as described in the notices given pursuant to clause (iv) of this Section 6(q) as have complied with item (iv) hereof, (ii) upon request of the Secured Party, deliver to each depository bank a letter in the form of Annex C hereto with respect to Secured Party’s Rights in such Deposit Account (or such other reasonable form as may be provided by the Depository Bank) and use commercially reasonable efforts to obtain the execution of such letter by each Depository Bank that the pledge of such Deposit Account has been recorded in the books and records of such bank and that Secured Party shall have dominion and control over such Deposit Account; (iii) upon request of the Secured Party, deliver to Secured Party all certificates or instruments, if any, now or hereafter representing or evidencing the Deposit Accounts, accompanied by duly executed instruments of transfer or assignment in blank, all in form and substance reasonably satisfactory to Secured Party; and (iv) notify Secured Party upon establishing any additional Deposit Accounts and, at the request of Secured Party, use commercially reasonable efforts to obtain from such depository bank an executed letter substantially in the form of Annex C (or such other reasonable form as may be provided by the Depository Bank) and deliver the same to Secured Party. Secured Party agrees not to exercise control over such Deposit Account unless an Event of Default shall have occurred and be continuing.

(t) Marking of Chattel Paper. At the request of Secured Party, not create any chattel paper without placing a legend on the chattel paper acceptable to Secured Party indicating that Secured Party has a security interest in the chattel paper.

(u) Modification of Accounts. In accordance with prudent business practices, endeavor to collect or cause to be collected from each account debtor under its accounts, as and

Multiparty Borrowing Base
Credit Facility Pledge & Security Agreement

when due, any and all amounts owing under such accounts. Except in the ordinary course of business consistent with prudent business practices and industry standards, without the prior written consent of Secured Party, no Debtor shall (i) grant any extension of time for any payment with respect to any of the accounts, (ii) compromise, compound, or settle any of the accounts for less than the full amount thereof, (iii) release, in whole or in part, any Person liable for payment of any of the accounts, (iv) allow any credit or discount for payment with respect to any account other than trade discounts granted in the ordinary course of business, (v) release any Lien or guaranty securing any account, or (vi) modify or substitute, or permit the modification or substitution of, any contract to which any of the Collateral which is accounts relates.

(v) Intellectual Property.

(i) Prosecute diligently all applications in respect of Intellectual Property, now or hereafter pending;

(ii) Except to the extent not required in such Debtor’s reasonable business judgment, make federal applications on all of its unpatented but patentable inventions and all of its registrable but unregistered Copyrights and Trademarks;

(iii) Preserve and maintain all of its material Rights in the Intellectual Property and protect the Intellectual Property from infringement, unfair competition, cancellation, or dilution by all appropriate action necessary in such Debtor’s reasonable business judgment including, without limitation, the commencement and prosecution of legal proceedings to recover damages for infringement and to defend and preserve its rights in the Intellectual Property;

(iv) Not abandon any of the Intellectual Property necessary to the conduct of its business in the exercise of such Debtor’s reasonable business judgment;

(v) Maintain the quality of any and all products and services with respect to which the Intellectual Property is used except to the extent not required in Debtor’s reasonable business judgment;

(vi) Not enter into any agreement including, but not limited to any licensing agreement, that is inconsistent with such Debtor’s obligations under this Security Agreement or any of the other First Lien Documents;

(vii) Give Secured Party prompt written notice if such Debtor shall obtain Rights to or become entitled to the benefit of any Intellectual Property not identified on Annex B-2 hereto; and

(viii) If an Event of Default exists, use its reasonable efforts to obtain any consents, waivers, or agreements necessary to enable Secured Party to exercise its rights and remedies with respect to the Intellectual Property.

7. DEFAULT; REMEDIES. If an Event of Default exists, Secured Party may, at its election (but subject to the terms and conditions of the Intercreditor Agreement and Borrowing Base Facility Credit Agreement), exercise any and all Rights available to a secured party under the UCC and

Multiparty Borrowing Base
Credit Facility Pledge & Security Agreement

other applicable Law, in addition to any and all other Rights afforded by the First Lien Documents, at law, in equity, or otherwise including, without limitation, (a) requiring a Debtor to assemble all or part of the Collateral and make it available to Secured Party at a place to be designated by Secured Party which is reasonably convenient to such Debtor and Secured Party, (b) to the extent permitted by each Debtor’s insurance carrier, surrendering any policies of insurance on all or part of the Collateral and receiving and applying the unearned premiums as a credit on the Obligations, (c) applying by appropriate judicial proceedings for appointment of a receiver for all or part of the Collateral (and such Debtor hereby consents to any such appointment), and (d) applying to the Obligations any cash held by Secured Party under this Security Agreement, including, without limitation, any cash in the Cash Collateral Account (defined in Section 8(h)).

(a) Notice. Reasonable notification of the time and place of any public sale of the Collateral of any Debtor, or reasonable notification of the time after which any private sale or other intended disposition of the Collateral is to be made, shall be sent to such Debtor and to any other Person entitled to notice under the UCC; provided that, if any of the Collateral threatens to decline speedily in value or is of the type customarily sold on a recognized market, Secured Party may sell or otherwise dispose of the Collateral without notification, advertisement, or other notice of any kind. It is agreed that notice sent or given not less than ten (10) Business Days prior to the taking of the action to which the notice relates is reasonable notification and notice for the purposes of this subparagraph.

(b) Condition of Collateral; Warranties. Secured Party has no obligation to clean-up or otherwise prepare the Collateral for sale. Secured Party may sell the Collateral without giving any warranties as to the Collateral. Secured Party may specifically disclaim any warranties of title or the like. This procedure will not be considered to affect adversely the commercial reasonableness of any sale of the Collateral.

(c) Compliance with Other Laws. Secured Party may comply with any applicable state or federal law requirements in connection with a disposition of the Collateral and compliance will not be considered to adversely affect the commercial reasonableness of any sale of the Collateral.

(d) Sales of Pledged Securities.

(i) Each Debtor agrees that, because of the Securities Act of 1933, as amended, or the rules and regulations promulgated thereunder (collectively, the “Securities Act”), or any other Laws or regulations, and for other reasons, there may be legal or practical restrictions or limitations affecting Secured Party in any attempts to dispose of certain portions of the Pledged Securities and for the enforcement of its Rights. For these reasons, Secured Party is hereby authorized by each Debtor, but not obligated, upon the occurrence and during the continuation of an Event of Default, to sell all or any part of the Pledged Securities at private sale, subject to an investment letter or in any other manner which will not require the Pledged Securities, or any part thereof, to be registered in accordance with the Securities Act or any other Laws or regulations, at a reasonable price at such private sale or other distribution in the manner mentioned above. Each Debtor understands that Secured Party may in its discretion approach a limited number of potential purchasers and that a sale under such circumstances may yield a lower price for the Pledged Securities, or any part thereof, than would otherwise be

Multiparty Borrowing Base
Credit Facility Pledge & Security Agreement

obtainable if such Collateral were either offered to a larger number of potential purchasers, registered under the Securities Act, or sold in the open market. Each Debtor agrees that any such private sale made under this Paragraph 7(d) shall be deemed to have been made in a commercially reasonable manner, and that Secured Party has no obligation to delay the sale of any Pledged Securities to permit the issuer thereof to register it for public sale under any applicable federal or state securities Laws.

(ii) Secured Party is authorized, in connection with any such sale, (A) to restrict the prospective bidders on or purchasers of any of the Pledged Securities to a limited number of sophisticated investors who will represent and agree that they are purchasing for their own account for investment and not with a view to the distribution or sale of any of such Pledged Securities, and (B) to impose such other limitations or conditions in connection with any such sale as Secured Party reasonably deems necessary in order to comply with applicable Law. Each Debtor covenants and agrees that it will execute and deliver such documents and take such other action as Secured Party reasonably deems necessary in order that any such sale may be made in compliance with applicable Law. Upon any such sale, Secured Party shall have the Right to deliver, assign, and transfer to the purchaser thereof the Pledged Securities so sold in accordance with any applicable federal and state securities laws. Each purchaser at any such sale shall hold the Pledged Securities so sold absolutely free from any claim or Right of any Debtor of whatsoever kind, including any equity or Right of redemption of such Debtor. Each Debtor, to the extent permitted by applicable Law, hereby specifically waives all Rights of redemption, stay, or appraisal which it has or may have under any Law now existing or hereafter enacted.

(iii) Each Debtor agrees that ten (10) Business Days’ written notice from Secured Party to such Debtor of Secured Party’s intention to make any such public or private sale or sale at a broker’s board or on a securities exchange shall constitute reasonable notice under the UCC. Such notice shall (A) in case of a public sale, state the time and place fixed for such sale, (B) in case of sale at a broker’s board or on a securities exchange, state the board or exchange at which such a sale is to be made and the day on which the Pledged Securities, or the portion thereof so being sold, will first be offered to sale at such board or exchange, and (C) in the case of a private sale, state the day after which such sale may be consummated. Any such public sale shall be held at such time or times within ordinary business hours and at such place or places as Secured Party may fix in the notice of such sale. At any such sale, the Pledged Securities may be sold in one lot as an entirety or in separate parcels, as Secured Party may reasonably determine. Secured Party shall not be obligated to make any such sale pursuant to any such notice. 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 same may be so adjourned.

(iv) In case of any sale of all or any part of the Pledged Securities on credit or for future delivery, the Pledged Securities so sold may be retained by Secured Party until the selling price is paid by the purchaser thereof, but Secured Party shall not incur any liability in case of the failure of such purchaser to take up and pay for the Pledged Securities so sold and in case of any such failure, such Pledged Securities may again be

Multiparty Borrowing Base
Credit Facility Pledge & Security Agreement

sold upon like notice. Secured Party, instead of exercising the power of sale herein conferred upon it, may proceed by a suit or suits at law or in equity to foreclose the Security Interests and sell the Pledged Securities, or any portion thereof, under a judgment or decree of a court or courts of competent jurisdiction.

(v) Without limiting the foregoing, or imposing upon Secured Party any obligations or duties not required by applicable Law, each Debtor acknowledges and agrees that, in foreclosing upon any of the Pledged Securities, or exercising any other Rights or remedies provided Secured Party hereunder or under applicable Law, Secured Party may, but shall not be required to, (A) qualify or restrict prospective purchasers of the Pledged Securities by requiring evidence of sophistication or creditworthiness, and requiring the execution and delivery of confidentiality agreements or other documents and agreements as a condition to such prospective purchasers’ receipt of information regarding the Pledged Securities or participation in any public or private foreclosure sale process, (B) provide to prospective purchasers business and financial information regarding such Debtor and its Subsidiaries available in the files of Secured Party at the time of commencing the foreclosure process, without the requirement that Secured Party obtain, or seek to obtain, any updated business or financial information or verify, or certify to prospective purchasers, the accuracy of any such business or financial information, or (C) offer for sale and sell the Pledged Securities with or without first employing an appraiser, investment banker, or broker with respect to the evaluation of the Pledged Securities, the solicitation of purchasers for Pledged Securities, or the manner of sale of Pledged Securities.

(e) Application of Proceeds. Secured Party shall apply the proceeds of any sale or other disposition of the Collateral under this Paragraph 7 in the order set forth in Section 4.03 of the Intercreditor Agreement, or if the Intercreditor Agreement has been terminated pursuant to its terms, then as follows: first, to the payment of all expenses incurred in retaking, holding, and preparing any of the Collateral for sale(s) or other disposition, in arranging for such sale(s) or other disposition, and in actually selling or disposing of the same (all of which are part of the Obligations); second, toward repayment of amounts expended by Secured Party under Paragraph 8; and third, toward payment of the balance of the Obligations in the order and manner specified in the Borrowing Base Facility Credit Agreement. Any surplus remaining shall be delivered to the relevant Debtor or as a court of competent jurisdiction may direct. If the proceeds are insufficient to pay the Obligations in full, Debtors shall remain liable for any deficiency.

(f) Sales on Credit. If Secured Party sells any of the Collateral of any Debtor upon credit, such Debtor will be credited only with payments actually made by the purchaser, received by the Secured Party, and applied to the indebtedness of the purchaser. In the event the purchaser fails to pay for the Collateral, Secured Party may resell the Collateral and such Debtor shall be credited with the proceeds of the sale.

8. OTHER RIGHTS OF SECURED PARTY.

(a) Performance. If any Debtor fails to keep its Collateral in good repair, working order, and condition, as required by the First Lien Documents, or fails to pay when due all Taxes on any of its Collateral in the manner required by the First Lien Documents, or fails to preserve the priority of the Security Interest in any of its Collateral, or fails to keep the Collateral insured

Multiparty Borrowing Base
Credit Facility Pledge & Security Agreement

as required by the First Lien Documents, or otherwise fails to perform any of its obligations under the First Lien Documents with respect to the Collateral, then Secured Party may, at its option, but without being required to do so, make such repairs, pay such Taxes, prosecute or defend any suits in relation to the Collateral, or insure and keep insured the Collateral in any amount deemed appropriate by Secured Party, or take all other action which a Debtor is required, but has failed or refused, to take under the First Lien Documents. Any sum which may be expended or paid by Secured Party under this subparagraph (including, without limitation, court costs and reasonable attorneys’ fees) shall bear interest from the dates of expenditure or payment at the Default Rate until paid and, together with such interest, shall be payable by such Debtor to Secured Party upon demand and shall be part of the Obligations.

(b) Collection. If an Event of Default exists and upon notice from Secured Party, each Obligor with respect to any payments on any of the Collateral (including, without limitation, dividends and other distributions with respect to the Pledged Securities and Partnership/Limited Liability Company Interests, payments on Collateral Notes, insurance proceeds payable by reason of loss or damage to any of the Collateral, or payments or distributions with respect to Deposit Accounts) is hereby authorized and directed by each Debtor to make payment directly to Secured Party, regardless of whether such Debtor was previously making collections thereon. Subject to Paragraph 8(f) hereof, until such notice is given, such Debtor is authorized to retain and expend all payments made on Collateral. If an Event of Default exists, Secured Party shall have the Right in its own name or in the name of such Debtor to compromise or extend time of payment with respect to all or any portion of the Collateral for such amounts and upon such terms as Secured Party may determine; to demand, collect, receive, receipt for, xxx for, compound, and give acquittances for any and all amounts due or to become due with respect to Collateral; to take control of cash and other proceeds of any Collateral; to endorse the name of such Debtor on any notes, acceptances, checks, drafts, money orders, or other evidences of payment on Collateral that may come into the possession of Secured Party; to sign the name of such Debtor on any invoice or xxxx of lading relating to any Collateral, on any drafts against Obligors or other Persons making payment with respect to Collateral, on assignments and verifications of accounts or other Collateral and on notices to Obligors making payment with respect to Collateral; to send requests for verification of obligations to any Obligor; and to do all other acts and things necessary to carry out the intent of this Security Agreement. If an Event of Default exists and any Obligor fails or refuses to make payment on any Collateral when due, Secured Party is authorized, in its sole discretion, either in its own name or in the name of such Debtor, to take such action as Secured Party shall deem appropriate for the collection of any amounts owed with respect to Collateral or upon which a delinquency exists. Regardless of any other provision hereof, however, Secured Party shall never be liable for its failure to collect, or for its failure to exercise diligence in the collection of, any amounts owed with respect to Collateral, nor shall it be under any duty whatsoever to anyone except such Debtor to account for funds that it shall actually receive hereunder. Without limiting the generality of the foregoing, Secured Party shall have no responsibility for ascertaining any maturities, calls, conversions, exchanges, offers, tenders, or similar matters relating to any Collateral, or for informing such Debtor with respect to any of such matters (irrespective of whether Secured Party actually has, or may be deemed to have, knowledge thereof). The receipt of Secured Party to any Obligor shall be a full and complete release, discharge, and acquittance to such Obligor, to the extent of any amount so paid to Secured Party.

Multiparty Borrowing Base
Credit Facility Pledge & Security Agreement

(c) Intellectual Property. For purposes of enabling Secured Party to exercise its Rights and remedies under this Security Agreement and enabling Secured Party and its successors and assigns to enjoy the full benefits of the Collateral, each Debtor hereby grants to Secured Party an irrevocable, nonexclusive license (exercisable without payment of royalty or other compensation to such Debtor upon an Event of Default) to use, license, or sublicense any of the Intellectual Property. Each Debtor shall provide Secured Party with reasonable access to all media in which any of the Intellectual Property may be recorded or stored and all computer programs used for the completion or printout thereof. This license shall also inure to the benefit of all successors, assigns, and transferees of Secured Party. If an Event of Default exists, Secured Party may require that each Debtor assign all of its Right, title, and interest in and to the Intellectual Property or any part thereof to Secured Party or such other Person as Secured Party may designate pursuant to documents satisfactory to Secured Party. If no Default or Event of Default exists, each Debtor shall have the exclusive, non-transferable Right and license to use the Intellectual Property in the ordinary course of business and the exclusive Right to grant to other Persons licenses and sublicenses with respect to the Intellectual Property for full and fair consideration.

(d) Record Ownership of Securities. If an Event of Default exists, Secured Party at any time may have any Collateral that is Pledged Securities and that is in the possession of Secured Party, or its nominee or nominees, registered in its name, or in the name of its nominee or nominees, as Secured Party; and, as to any Collateral that is Pledged Securities so registered, Secured Party shall execute and deliver (or cause to be executed and delivered) to each Debtor all such proxies, powers of attorney, dividend coupons or orders, and other documents as such Debtor may reasonably request for the purpose of enabling such Debtor to exercise the voting Rights and powers which it is entitled to exercise under this Security Agreement or to receive the dividends and other distributions and payments in respect of such Collateral that is Pledged Securities or proceeds thereof which it is authorized to receive and retain under this Security Agreement.

(e) Voting of Securities. As long as no Event of Default exists, each Debtor is entitled to exercise all voting Rights pertaining to any Pledged Securities and Partnership/Limited Liability Company Interests; provided however, that no vote shall be cast or consent, waiver, or ratification given or action taken without the prior written consent of Secured Party which would be inconsistent with or violate any provision of this Security Agreement or the Borrowing Base Facility Credit Agreement; and provided further that such Debtor shall give Secured Party at least five Business Days’ prior written notice in the form of an officers’ certificate of the manner in which it intends to exercise, or the reasons for refraining from exercising, any voting or other consensual Rights pertaining to the Collateral or any part thereof which might have a Material Adverse Effect on the value of the Collateral or any part thereof. If an Event of Default exists and if Secured Party elects to exercise such Right, the Right to vote any Pledged Securities shall be vested exclusively in Secured Party. To this end, each Debtor hereby irrevocably constitutes and appoints Secured Party the proxy and attorney-in-fact of such Debtor, with full power of substitution, to vote, and to act with respect to, any and all Collateral that is Pledged Securities standing in the name of such Debtor or with respect to which such Debtor is entitled to vote and act, subject to the understanding that such proxy may not be exercised unless an Event of Default exists. The proxy herein granted is coupled with an interest, is irrevocable, and shall continue until the Obligations have been paid and performed in full.

(f) Certain Proceeds. Notwithstanding any contrary provision herein, any and all

(i) dividends, interest, or other distributions 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 Collateral;

(ii) dividends, interest, or other distributions hereafter paid or payable in cash in respect of any Collateral in connection with a partial or total liquidation or dissolution, or in connection with a reduction of capital, capital surplus, or paid-in-surplus;

(iii) cash paid, payable, or otherwise distributed in redemption of, or in exchange for, any Collateral; and

(iv) dividends, interest, or other distributions paid or payable in violation of the First Lien Documents,

shall be part of the Collateral hereunder, and shall, if received by any Debtor, be held in trust for the benefit of Secured Party, and shall forthwith be delivered to Secured Party (accompanied by proper instruments of assignment and/or stock and/or bond powers executed by such Debtor in accordance with Secured Party’s instructions) to be held subject to the terms of this Security Agreement. Any cash proceeds of Collateral which come into the possession of Secured Party during the continuance of an Event of Default (including, without limitation, insurance proceeds) may, at Secured Party’s option, be applied in whole or in part to the Obligations (to the extent then due), be released in whole or in part to or on the written instructions of any Debtor for any general or specific purpose, or be retained in whole or in part by Secured Party as additional Collateral. Any cash Collateral in the possession of Secured Party may be invested by Secured Party in certificates of deposit issued by Secured Party (if Secured Party issues such certificates) or by any state or national bank having combined capital and surplus greater than $100,000,000 with a short term rating from Xxxxx’x and S&P of P-1 and A-1+, respectively, or in securities issued or guaranteed by the United States or any agency thereof. Secured Party shall never be obligated to make any such investment and shall never have any liability to any Debtor for any loss which may result therefrom. All interest and other amounts earned from any investment of Collateral may be dealt with by Secured Party in the same manner as other cash Collateral. Except as specifically provided herein, the provisions of this subparagraph are applicable whether or not a Default or Event of Default exists.

(g) Use and Operation of Collateral. Should any Collateral come into the possession of Secured Party, Secured Party may use or operate such Collateral for the purpose of preserving it or its value pursuant to the order of a court of appropriate jurisdiction or in accordance with any other Rights held by Secured Party in respect of such Collateral. Each Debtor covenants to promptly reimburse and pay to Secured Party, at Secured Party’s request, the amount of all reasonable expenses (including, without limitation, the cost of any insurance and payment of Taxes or other charges) incurred by Secured Party in connection with its custody and preservation of Collateral, and all such expenses, costs, Taxes, and other charges shall bear interest at the Default Rate until repaid and, together with such interest, shall be payable by such Debtor to Secured Party upon demand and shall become part of the Obligations. However, the risk of accidental loss or damage to, or diminution in value of, Collateral is on such Debtor, and Secured

Multiparty Borrowing Base
Credit Facility Pledge & Security Agreement

Party shall have no liability whatever for failure to obtain or maintain insurance, nor to determine whether any insurance ever in force is adequate as to amount or as to the risks insured. With respect to Collateral that is in the possession of Secured Party, Secured Party shall use reasonable care in the custody and preservation of such Collateral but shall have no duty to fix or preserve Rights against prior parties to such Collateral and shall never be liable for any failure to use diligence to collect any amount payable in respect of such Collateral, but shall be liable only to account to such Debtor for what it may actually collect or receive thereon. The provisions of this subparagraph are applicable whether or not an Event of Default exists.

(h) Cash Collateral Account. If an Event of Default exists and is continuing, Secured Party shall have, and each Debtor hereby grants to Secured Party, the Right and authority to transfer all funds on deposit in the Deposit Accounts to a Cash Collateral Account (herein so called) maintained with a depository institution acceptable to Secured Party and subject to the exclusive direction, domain, and control of Secured Party, and no disbursements or withdrawals shall be permitted to be made by such Debtor from such Cash Collateral Account; provided, however, Secured Party shall permit disbursements and withdrawals from the Cash Collateral Account to the extent necessary to comply with applicable Law, such as for the payment of payroll taxes and other obligations for which a Debtor (or a member of its governing body) would be liable under applicable Law. Such Cash Collateral Account shall be subject to the Security Interest and Liens in favor of Secured Party herein created, and each Debtor hereby grants a security interest to Secured Party on behalf of the Beneficiaries in and to, such Cash Collateral Account and all checks, drafts, and other items ever received by such Debtor for deposit therein. Furthermore, if an Event of Default exists, Secured Party shall have the Right, at any time in its discretion without prior notice to Debtors, (i) to transfer to or to register in the name of Secured Party or any Beneficiary or nominee any certificates of deposit or deposit instruments constituting Deposit Accounts and shall have the Right to exchange such certificates or instruments representing Deposit Accounts for certificates or instruments of smaller or larger denominations and (ii) to take and apply against the Obligations any and all funds then or thereafter on deposit in the Cash Collateral Account or otherwise constituting Deposit Accounts. If not notified before taking any of the foregoing actions, Secured Party shall promptly, and in any event within two (2) Business Days, notify Debtors after taking any of the foregoing actions.

(i) Power of Attorney. Each Debtor hereby irrevocably constitutes and appoints Secured Party 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 name of such Debtor or in its own name, to take after the occurrence and during the continuance of an Event of Default any and all action and to execute any and all documents and instruments which Secured Party at any time and from time to time deems necessary or desirable to accomplish the purposes of this Security Agreement and, without limiting the generality of the foregoing, each Debtor hereby gives Secured Party the power and Right on behalf of such Debtor and in its own name to do any of the following from time to time after the occurrence and during the continuance of an Event of Default without notice to or the consent of such Debtor:

(i) to transfer any and all funds on deposit in the Deposit Accounts to the Cash Collateral Account as set forth in herein;

(ii) to receive, endorse, and collect any drafts or other instruments or documents in connection with clause (b) above and this
clause (i);

Multiparty Borrowing Base
Credit Facility Pledge & Security Agreement

(iii) to use the Intellectual Property or to grant or issue any exclusive (if such Debtor has exclusive rights to such Intellectual Property) or non-exclusive license under the Intellectual Property to anyone else, and to perform any act necessary for the Secured Party to assign, pledge, convey, or otherwise transfer title in or dispose of the Intellectual Property to any other Person;

(iv) to demand, xxx for, collect, or receive, in the name of such Debtor or in its own name, any money or property at any time payable or receivable on account of or in exchange for any of the Collateral and, in connection therewith, endorse checks, notes, drafts, acceptances, money orders, documents of title or any other instruments for the payment of money under the Collateral or any policy of insurance;

(v) to pay or discharge taxes, Liens, or other encumbrances levied or placed on or threatened against the Collateral;

(vi) to notify post office authorities to change the address for delivery of mail to such Debtor to an address designated by Secured Party and to receive, open, and (with respect to mail relating to payments on Collateral) take action with respect to mail addressed to such Debtor; provided however, Secured Party shall promptly deliver to Debtors any mail not relating to Collateral or the preservation or enforcement of Secured Party’s rights with respect to the Collateral; and

(vii) (A) to direct account debtors and any other parties liable for any payment under any of the Collateral to make payment of any and all monies due and to become due thereunder directly to Secured Party or as Secured Party shall direct; (B) to receive payment of and receipt for any and all monies, claims, and other amounts due and to become due at any time in respect of or arising out of any Collateral; (C) to sign and endorse any invoices, freight or express bills, bills of lading, storage or warehouse receipts, drafts against debtors, assignments, proxies, stock powers, verifications, and notices in connection with accounts and other documents relating to the Collateral; (D) to commence and prosecute any suit, action, or proceeding 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; (E) to defend any suit, action, or proceeding brought against such Debtor with respect to any Collateral; (F) to settle, compromise, or adjust any suit, action, or proceeding described above and, in connection therewith, to give such discharges or releases as Secured Party may deem appropriate; (G) to exchange any of the Collateral for other property upon any merger, consolidation, reorganization, recapitalization, or other readjustment of the issuer thereof and, in connection therewith, deposit any of the Collateral with any committee, depositary, transfer agent, registrar, or other designated agency upon such terms as Secured Party may determine; (H) to add or release any guarantor, endorser, surety, or other party to any of the Collateral; (I) to renew, extend, or otherwise change the terms and conditions of any of the Collateral; (J) to endorse such Debtor’s name on all applications, documents, papers, and instruments necessary or desirable in order for Secured Party to use or maintain any of the Intellectual Property; (K) to make, settle, compromise or adjust any claims under or pertaining to any of the Collateral (including claims under any policy of insurance); (L) to execute on behalf of such Debtor any financing statements or continuation statements with respect to the Security Interests created hereby, and to do any and all acts and things to protect and

Multiparty Borrowing Base
Credit Facility Pledge & Security Agreement

preserve the Collateral including, without limitation, the protection and prosecution of all Rights included in the Collateral; and (M) to sell, transfer, pledge, convey, make any agreement with respect to or otherwise deal with any of the Collateral as fully and completely as though Secured Party were the absolute owner thereof for all purposes, and to do, at Secured Party’s option and such Debtor’s expense, at any time, or from time to time, all acts and things which Secured Party deems necessary to protect, preserve, maintain, or realize upon the Collateral and Secured Party’s security interest therein.

This power of attorney is a power coupled with an interest and shall be irrevocable. Secured Party shall be under no duty to exercise or withhold the exercise of any of the Rights, powers, privileges, and options expressly or implicitly granted to Secured Party in this Security Agreement, and shall not be liable for any failure to do so or any delay in doing so. Neither Secured Party nor any Person designated by Secured Party shall be liable for any act or omission or for any error of judgment or any mistake of fact or Law except for the failure to account to Debtors for funds received by Secured Party and except for failure to use reasonable care in the custody and preservation of Collateral in its possession. This power of attorney is conferred on Secured Party solely to protect, preserve, maintain, and realize upon its Security Interest in the Collateral. Secured Party shall not be responsible for any decline in the value of the Collateral and shall not be required to take any steps to preserve rights against prior parties or to protect, preserve, or maintain any Lien given to secure the Collateral.

(j) Purchase Money Collateral. To the extent that Secured Party or any Beneficiary has advanced or will advance funds to or for the account of any Debtor to enable such Debtor to purchase or otherwise acquire Rights in Collateral, Secured Party or such Beneficiary, at its option, may pay such funds (i) directly to the Person from whom such Debtor will make such purchase or acquire such Rights, or (ii) to such Debtor, in which case such Debtor covenants to promptly pay the same to such Person, and forthwith furnish to Secured Party evidence satisfactory to Secured Party that such payment has been made from the funds so provided.

(k) Subrogation. If any of the Obligations are given in renewal or extension or applied toward the payment of indebtedness secured by any Lien, Secured Party shall be, and is hereby, subrogated to all of the Rights, titles, interests, and Liens securing the indebtedness so renewed, extended, or paid.

(1) Indemnification. Each Debtor hereby assumes all liability for the Collateral owned by it, for the Security Interest granted by it, and for any use, possession, maintenance, and management of, all or any of the Collateral owned by it including, without limitation, any Taxes arising as a result of, or in connection with, the transactions contemplated herein, and agrees to assume liability for, and to indemnify and hold Secured Party and each Beneficiary harmless from and against, any and all claims, causes of action, or liability, for injuries to or deaths of Persons and damage to property, howsoever arising from or incident to such use, possession, maintenance, and management, whether such Persons be agents or employees of such Debtor or of third parties, or such damage be to property of such Debtor or of others. Each Debtor agrees to indemnify, save, and hold Secured Party and each Beneficiary harmless from and against, and covenants to defend Secured Party and each Beneficiary against, any and all losses, damages, claims, costs, penalties, liabilities, and expenses (collectively, “Claims”), including, without limitation, court costs and attorneys’ fees, and any of the foregoing arising from the negligence of Secured Party or any Beneficiary, or any of their respective officers, employees, agents,

Multiparty Borrowing Base
Credit Facility Pledge & Security Agreement

advisors, employees, or representatives, howsoever arising or incurred because of, incident to, or with respect to the Collateral owned by such Debtor or any use, possession, maintenance, or management thereof; provided however, that the indemnity set forth in this Paragraph 8(l) will not apply to Claims caused by the gross negligence or willful misconduct of Secured Party or any Beneficiary.

9. MISCELLANEOUS.

(a) Continuing Security Interest. This Security Agreement creates a continuing security interest in the Collateral and shall (i) remain in full force and effect until the payment in full of the Obligations (other than any L/C Obligations that are Cash Collateralized or any contingent indemnity obligations), termination of the Revolving Commitments or their reduction to zero, and compliance with Section 10.01(e) of the Borrowing Base Facility Credit Agreement with respect to outstanding Swap Contracts secured by any Loan Document or in accordance with Section 10.21 of the Pipeline Credit Agreement; and (ii) inure to the benefit of and be enforceable by Secured Party, Beneficiaries, and their respective successors, transferees, and permitted assigns. Without limiting the generality of the foregoing clause (ii), Secured Party and Beneficiaries may assign or otherwise transfer any of their respective Rights under this Security Agreement to any other Person in accordance with the terms and provisions of Section 10.07 of the Borrowing Base Facility Credit Agreement, and to the extent of such assignment or transfer such Person shall thereupon become vested with all the Rights and benefits in respect thereof granted herein or otherwise to Secured Party or Beneficiaries, as the case may be. Upon payment in full of the Obligations (other than any L/C Obligations that are Cash Collateralized or any contingent indemnity obligations), termination of the Revolving Commitments or their reduction to zero, and compliance with Section 10.01(e) of the Credit Agreement with respect to outstanding Swap Contracts secured by any Loan Document, each Debtor shall be entitled to the return, upon its request and at its expense, of such of the Collateral owned by it as shall not have been sold or otherwise applied pursuant to the terms hereof.

(b) Reference to Miscellaneous Provisions. This Security Agreement is one of the “Loan Documents” referred to in the Borrowing Base Facility Credit Agreement, and all provisions relating to Loan Documents set forth in Article X of the Borrowing Base Facility Credit Agreement are incorporated herein by reference, the same as if set forth herein verbatim.

(c) Term; Release of Liens. The Secured Party shall release the Liens created by this Security Agreement in accordance with Section 10.01 of the Borrowing Base Facility Credit Agreement and Section 10.21 of the Pipeline Credit Agreement; provided that no Obligor, if any, on any of the Collateral shall ever be obligated to make inquiry as to the termination of this Security Agreement, but shall be fully protected in making payment directly to Secured Party until actual notice of such total payment of the Obligations is received by such Obligor. At such time as the Liens created by this Security Agreement are to be released pursuant to this paragraph, Secured Party shall, at the request and expense of Debtors following such termination, promptly deliver to a Debtor any Collateral held by the Secured Party hereunder, and promptly execute and deliver to such Debtor such documents and instruments as such Debtor shall reasonably request to evidence such termination and release as provided in the Credit Agreement. In addition, if any of the Collateral shall be sold, transferred, assigned or otherwise disposed of by such Debtor in a transaction permitted by the Borrowing Base Facility Credit Agreement, then the

Multiparty Borrowing Base
Credit Facility Pledge & Security Agreement

Secured Party, at the request and expense of such Debtor, shall promptly execute and deliver releases as provided in the Borrowing Base Facility Credit Agreement.

(d) Actions Not Releases. The Security Interest and each Debtor’s obligations and Secured Party’s Rights hereunder shall not be released, diminished, impaired, or adversely affected by the occurrence of any one or more of the following events: (i) the taking or accepting of any other security or assurance for any or all of the Obligations; (ii) any release, surrender, exchange, subordination, or loss of any security or assurance at any time existing in connection with any or all of the Obligations; (iii) the modification of, amendment to, or waiver of compliance with any terms of any of the other First Lien Documents without the notification or consent of any Debtor, except as required therein (the Right to such notification or consent being herein specifically waived by each Debtor); (iv) the insolvency, bankruptcy, or lack of corporate or trust power of any party at any time liable for the payment of any or all of the Obligations, whether now existing or hereafter occurring; (v) any renewal, extension, or rearrangement of the payment of any or all of the Obligations, either with or without notice to or consent of each Debtor, or any adjustment, indulgence, forbearance, or compromise that may be granted or given by Secured Party or any Beneficiary to any Debtor; (vi) any neglect, delay, omission, failure, or refusal of Secured Party or any Beneficiary to take or prosecute any action in connection with any other agreement, document, guaranty, or instrument evidencing, securing, or assuring the payment of all or any of the Obligations; (vii) any failure of Secured Party or any Beneficiary to notify any Debtor of any renewal, extension, or assignment of the Obligations or any part thereof, or the release of any Collateral or other security, or of any other action taken or refrained from being taken by Secured Party or any Beneficiary against any Debtor or any new agreement between or among Secured Party or one or more Beneficiaries and any Debtor, it being understood that except as expressly provided herein, neither Secured Party nor any Beneficiary shall be required to give any Debtor any notice of any kind under any circumstances whatsoever with respect to or in connection with the Obligations including, without limitation, notice of acceptance of this Security Agreement or any Collateral ever delivered to or for the account of Secured Party hereunder except to the extent expressly provided for herein or under the Borrowing Base Facility Credit Agreement; (viii) the illegality, invalidity, or unenforceability of all or any part of the Obligations against any party obligated with respect thereto by reason of the fact that the Obligations, or the interest paid or payable with respect thereto, exceeds the amount permitted by Law, the act of creating the Obligations, or any part thereof, is ultra xxxxx, or the officers, partners, or trustees creating same acted in excess of their authority, or for any other reason; or (ix) if any payment by any party obligated with respect thereto is held to constitute a preference under applicable Laws or for any other reason Secured Party or any Beneficiary is required to refund such payment or pay the amount thereof to someone else.

(e) Waivers. Except to the extent expressly otherwise provided herein or in other First Lien Documents and to the fullest extent permitted by applicable Law, each Debtor waives (i) any Right to require Secured Party or any Beneficiary to proceed against any other Person, to exhaust its Rights in Collateral, or to pursue any other Right which Secured Party or any Beneficiary may have; (ii) with respect to the Obligations, presentment and demand for payment, protest, notice of protest and nonpayment, and notice of the intention to accelerate; and (iii) all Rights of marshaling in respect of any and all of the Collateral.

(f) Financing Statement; Authorization. Secured Party shall be entitled at any time to file this Security Agreement or a carbon, photographic, or other reproduction of this Security

Multiparty Borrowing Base
Credit Facility Pledge & Security Agreement

Agreement, as a financing statement, but the failure of Secured Party to do so shall not impair the validity or enforceability of this Security Agreement. Each Debtor hereby irrevocably authorizes Secured Party at any time and from time to time to file in any UCC jurisdiction any initial or other financing statements and amendments thereto that (i) indicate the Collateral (A) as “all assets of Debtor” or words of similar effect, regardless of whether any particular asset comprised in the Collateral falls within the scope of Article 9 of the UCC of the state or such jurisdiction or whether such assets are included in the Collateral hereunder, or (B) as being of an equal or lesser scope or with greater detail, and (ii) contain any other information required by Article 9 of the UCC of the state or such jurisdiction for the sufficiency or filing office acceptance of any financing statement or amendment, including (A) whether such Debtor is an organization, the type of organization, and any organization identification number issued to such Debtor and, (B) in the case of a financing statement filed as a fixture filing or indicating Collateral that is as-extracted collateral or timber to be cut, a sufficient description of real property to which the Collateral relates. Each Debtor agrees to furnish any such information to Secured Party promptly upon request.

(g) Amendments. This Security Agreement may be amended only by an instrument in writing executed jointly by such Debtor and Secured Party, and supplemented only by documents delivered or to be delivered in accordance with the express terms hereof.

(h) Multiple Counterparts. This Security Agreement has been executed in a number of identical counterparts, each of which shall be deemed an original for all purposes and all of which constitute, collectively, one agreement; but, in making proof of this Security Agreement, it shall not be necessary to produce or account for more than one such counterpart.

(i) Additional Debtors. Any Person may become a party hereto by signing and delivering to the Secured Party an Assumption Agreement in the form of Annex E hereto, whereupon such Person shall become a “Debtor” as defined herein. The execution and delivery of any instrument adding an additional Debtor as a party to this Agreement shall not require the consent of any Debtor hereunder. The rights and obligations of each Debtor hereunder shall remain in full force and effect notwithstanding the addition of any new Debtor hereunder.

(j) Parties Bound; Assignment. This Security Agreement shall be binding on each Debtor and each of Debtor’s legal representatives, successors, and assigns and shall inure to the benefit of Secured Party and Secured Party’s successors and permitted assigns.

(i) Secured Party is the agent for each Beneficiary under the Intercreditor Agreement, each Borrowing Base Facility Secured Party under the Borrowing Base Facility Credit Agreement and each Affiliate of a Borrowing Base Facility Lender and Approved Hedge Counterparty party to any Lender Hedging Agreement. The Security Interest and all Rights granted to Secured Party hereunder or in connection herewith are for the ratable benefit of each Beneficiary, each Borrowing Base Facility Secured Party and each such Affiliate, and Secured Party may, without the joinder of any Beneficiary, Borrowing Base Facility Secured Party or any such Affiliate, exercise any and all Rights in favor of Secured Party or any Beneficiary, any Borrowing Base Facility Secured Party or any such Affiliates hereunder, including, without limitation, conducting any foreclosure sales hereunder, and executing full or partial releases hereof, amendments or modifications hereto, or consents or waivers hereunder. The Rights of each Beneficiary,

Multiparty Borrowing Base
Credit Facility Pledge & Security Agreement

Borrowing Base Facility Secured Party or any such Affiliate vis-à-vis Secured Party and each other Beneficiary, Borrowing Base Facility Secured Party or any such Affiliate may be subject to one or more separate agreements between or among such parties, but no Debtor need inquire about any such agreement or be subject to any terms thereof unless such Debtor specifically joins therein; and consequently, no Debtor nor such Debtor’s legal representatives, successors, and assigns shall be entitled to any benefits or provisions of any such separate agreements or be entitled to rely upon or raise as a defense, in any manner whatsoever, the failure or refusal of any party thereto to comply with the provisions thereof.

(ii) Except for this Security Agreement and assignments made in furtherance hereof, no Debtor may, without the prior written consent of Secured Party, assign any Rights, duties, or obligations hereunder.

(k) Governing Law. The substantive laws of the State of New York, except to the extent the laws of another jurisdiction govern the creation, perfection, validity, or enforcement of liens under this Security Agreement, and the applicable federal laws of the United States, shall govern the validity, construction, enforcement and interpretation of this security agreement and all of the other loan documents.

(l) The provisions of Section 10.10 of the Borrowing Base Facility Credit Agreement are incorporated herein as if set forth herein.

(m) All notices given pursuant hereto shall be given in the manner set forth in the Borrowing Base Facility Credit Agreement, if to Secured Party, to the address of Secured Party therein set forth and if to a Debtor, to the following address:

DEPOSIT ACCOUNT CONTROL AGREEMENT

_______________, 20__

_________________________

Ladies and Gentlemen:

This letter is to notify you (the “Depository Bank”) that, pursuant to that certain Amended and Restated Pledge and Security Agreement dated as of September 21, 2010 (as amended, modified, supplemented, or restated from time to time, the “Security Agreement”), ____________________, a company organized under the laws of ___________ (the “Pledgor”), has granted to Royal Bank of Canada as Administrative Agent and Collateral Agent (“Pledgee”) a first priority security interest in and lien upon, (a) Account No. __________ (the “Account”) maintained by Pledgor with you, (b) any extensions or renewals of the Account if the Account is one which may be extended or renewed, and (c) all of Pledgor’s right, title, and interest (whether now existing or hereafter created or arising) in and to the Account, all sums from time to time on deposit therein, credited thereto, or payable thereon, all instruments, documents, certificates, and other writings evidencing the Account, and any and all proceeds of any thereof (the items described in clauses (a), (b) and (c) being herein collectively called the “Collateral”),

In connection therewith, the parties hereto agree (which agreement by Pledgor will be construed as instructions to the Depository Bank):

1.		The Depository Bank is instructed to register the pledge on its books and hold the Collateral in a pledged status account.

2.		The Depository Bank is instructed to deliver to Pledgee copies of monthly statements on the account(s) identified below:

3.		The Account will be styled:

4.		All dividends, interest, gains, and other profits on the Collateral will be reported in the name and tax identification number of Pledgor.

5.		If so notified by Pledgee, the Depository Bank will not, without the prior written consent of Pledgee, allow any of the Collateral or any interest therein to be sold, transferred, or withdrawn by or for the benefit of Pledgor.

6.		This letter agreement gives Pledgee “control” of the Account and the Collateral. The Depository Bank agrees to comply with any order or instruction from Pledgee as to the withdrawal or disposition of any funds from time to time credited to the Account, or as to any other matters relating to the Collateral, without the further consent of Pledgor. The Depository Bank shall be

Credit Facility Pledge & Security Agreement

Annex C - Page 1

fully entitled to rely upon such instructions from Pledgee even if such instructions are contrary to any instructions or demands that Pledgor may give to the Depository Bank.

7.		Pledgee agrees to indemnify and hold the Depository Bank, its officers and employees, harmless from and against any and all claims, causes of action, liabilities, lawsuits, demands, and/or damages, including, without limitation any and all costs, including court costs and reasonable attorneys’ fees, that may arise or result from the Depository Bank complying with the instructions and orders of Pledgee given in connection with Pledgee’s exercise of its control over and secured rights in the Account and the Collateral except to the extent that such claims, causes of action, liabilities, lawsuits, demands, and/or damages are found in a final, non-appealable judgment by a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of the Depository Bank.

8.		Pledgor agrees to indemnify and hold the Depository Bank, its officers and employees, harmless from and against any and all claims, causes of action, liabilities, lawsuits, demands, and/or damages, including, without limitation, any and all costs, including court costs and reasonable attorneys’ fees, that may arise or result from the Depository Bank entering into and performing its obligations under this letter agreement except to the extent that such claims, causes of action, liabilities, lawsuits, demands, and/or damages are found in a final, non-appealable judgment by a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of the Depository Bank.

9.		The Depository Bank represents that it has not received notice regarding any lien, encumbrance, or other claim to the Account or the Collateral from any person other than pursuant to this letter agreement and has not entered into another agreement with any other party to act on such party’s instructions with respect to the Account. The Depository Bank further agrees not to enter into any such agreement with any other party.

10.		The Depository Bank subordinates to the security interest of Pledgee any right of recoupment or set-off, or to assert any security interest or other lien, that it may at any time have against or in any of the Collateral on account of any credit or other obligations owed to the Depository Bank by Pledgor or any other person. The Depository Bank may, however, from time to time debit the Account for any of its customary charges in maintaining the Account or for reimbursement for the reversal of any provisional credits granted by the Depository Bank to the Account, to the extent, in each case, that Pledgor has not separately paid or reimbursed Depository Bank therefor.

11.		To the extent a conflict exists between the terms of this letter agreement and any account agreement between Pledgor and the Depository Bank, the terms of this letter agreement will control.

12.		The terms of this letter agreement will in no way be modified except by a writing signed by all parties hereto.

13.		This letter agreement will terminate upon notice of termination hereof delivered by Pledgee to Depository Bank.
