The proceeds of Loan Advances shall be used only for those items on the Budget, which Lender has approved, which includes the expenses of Oil & Gas and certain expenses of Energy, and which shall be limited to (a) general and administrative expenses related to the business of Oil & Gas, (b) fees incurred by the Borrower’s professionals as allocated by the Budget, and (c) certain, limited, expenses relating to corporate overhead and governance.

(b) During the Term, the Lender may make one or more advances of the Development Loan in its sole and absolute discretion. Borrower acknowledges and agrees that it shall have no ability to require or demand any advance from Lender.

1.2 Borrowing Procedures (Excluding Development Loans).

(a) Subject to the provisions of Section 8.1 of this Agreement, as applicable, and provided that there does not then exist a Default or an Event of Default, Borrower may, from time to time, request that Lender make Loan Advances to Borrower in accordance with the terms of this Agreement. Lender shall fund requests for Loan Advances as follows: (i) by the close of business on the first Business Day after such request is received if the request is received prior to 1:00 p.m. prevailing Mountain Time; and (ii) by the close of the second Business Day after such request is received if the request is received after that time.

(b) The initial request for a Loan Advance shall be made by transmission to Lender of a fully executed Borrowing Certificate on or before the Closing Date substantially in the form of Exhibit “B” (the “Borrowing Certificate”), which certificate shall specify (i) the amount to be borrowed (which shall be equal to or less than the Maximum Amount in effect as of the Closing Date), and (ii) the use of the proceeds (including an itemized list of all checks, ACH or wire transactions, or other items to be funded with such proceeds); provided, that, Lender shall at any time have the right to review and comment, in the exercise of its reasonable discretion to the extent necessary to insure Borrower’s compliance with the Budget, on the amount of such request. Borrower shall make no more than two (2) requests for Loan Advances per calendar week.

(c) Subsequent requests for Loan Advances shall be made by transmission to Lender of a fully executed Borrowing Certificate as provided in Section 1.2(b), executed by an authorized officer of Borrower. Borrower agrees that the delivery of any such Borrowing Certificate shall constitute a certification by Borrower that (i) the requested Loan and the intended use thereof are consistent with the terms of this Agreement and is necessary for Borrower to satisfy its obligations as set forth on the then current Budget, (ii) the proceeds of all prior Loans have been applied in conformity with the requirements of this Agreement, (iii) all of the representations contained in Article 5 of this Agreement are true and correct, (iv) Borrower has observed and performed in all material respects all applicable covenants and agreements contained herein and in the other Loan Documents and the DIP Order, and satisfied each condition to such Loan contained herein or in the other Loan Documents or in the DIP Order (as applicable), to be observed, performed or satisfied by Borrower, (v) the making of the requested Loan is in compliance with all provisions of this Agreement and the other Loan Documents, (vi) such authorized officer has no knowledge of any Default or Event of Default, and (vii) the conditions set forth in Article 8 of this Agreement are satisfied.

(d) Borrower shall reimburse Lender and hold Lender harmless from any loss or expense that Lender may sustain or incur as a consequence of the failure of Borrower to borrow additional Loans after Borrower has requested (or is deemed to have requested) such additional Loans, including any such loss or expense arising from the liquidation or re-employment of funds obtained by Lender to maintain the Loans or from fees payable to terminate the deposits from which such funds were obtained.

(e) It is expressly understood and agreed that the Maximum Amount is a maximum ceiling on Loan Advances to Borrower; provided, however, that it is agreed that should the Obligations ever exceed the ceiling so determined or any other limitation

set forth in this Agreement, such amounts shall nevertheless constitute Obligations secured by the Security Interest of Lender and, as such, shall be entitled to all benefits thereof and security therefor.

(f) All Loan Advances shall be deposited only into the DIP Facility Account, which is a bank account that is subject to the Deposit Account Control Agreement and shall not be transferred into a bank account for which any other creditor has custody, control or a Lien.

1.3 Interest. Interest shall accrue on the outstanding principal balance of the Loans at the Interest Rate. All interest accrued on the outstanding principal balance of the Loans shall be calculated on the basis of a year of three hundred sixty (360) days and the actual number of days elapsed in each month. Accrued interest shall be added to the outstanding principal balance of the Loans on the first Business Day of each calendar month following the month in which such interest accrues.

1.4 Allocation of Payments and Limit of Interest. Any amounts received by Lender from Borrower shall be applied pro tanto to the Obligations as follows: first to pay any interest, fees costs, charges, indemnities, and expenses then due to Lender under the Loan Documents, until paid in full, and second, to repay the principal amount of all outstanding Obligations until paid in full. Upon the occurrence and during the continuance of an Event of Default, all Revenues received by Lender from Borrower shall be applied pro tanto to the Obligations in such manner as Lender shall determine in its sole discretion. Lender does not intend to charge interest at a rate in excess of the highest rate permitted by Applicable Law. Interest on any outstanding principal balance shall be spread over the entire period that such principal balance is outstanding. Any excess interest charges paid by Borrower to Lender shall be applied to reduce the outstanding principal balance of the Obligations.

1.5 Termination.

(a) This Agreement shall expire on the Termination Date.

(b) Upon the termination of this Agreement for any reason as herein provided, Borrower shall pay, discharge and satisfy, no later than the effective date of such termination, the Loan Advances, all accrued and unpaid interest and fees, and all other non-contingent Obligations then outstanding.

(c) All undertakings, agreements, covenants, warranties and representations of Borrower contained in this Agreement and the other Loan Documents shall survive any such termination, and Lender shall retain each and every Security Interest, and all other rights and remedies of Lender under this Agreement and the other Loan Documents, notwithstanding such termination, until Borrower has paid the amounts described in Section 1.5(b).

(d) Notwithstanding the payment in full of the Loans, all accrued and unpaid interest and fees, and all other non-contingent Obligations outstanding, Lender shall not be required to terminate its Security Interests unless, with respect to any loss or damage Lender may incur as a result of dishonored checks or other items of payment

received by Lender from Borrower or any Account Debtor and applied to the Obligations, Lender shall have retained such monetary reserves and its Security Interest for such period of time as Lender, in its reasonable discretion, may deem necessary to protect Lender from any such loss or damage.

ARTICLE III - GRANT OF SECURITY INTEREST

3.1 Grant of Security Interest. To secure the payment, performance and observance of the Obligations, the Borrower grants and hereby assigns, mortgages, hypothecates and pledges, to Lender all of the Collateral, and grants to Lender a continuing security interest in, and a Lien upon, and a right of set off against, all of the Collateral. The Borrower acknowledges that the Security Interest and Lien granted to the Lender pursuant to this Article III is and continues to be an allowed, valid and perfected, first priority Security Interest and Lien upon the Collateral subject only to the Permitted Liens (other than the DIP Facility Account which shall not be subject to the Permitted Liens).

3.2 Continued Priority of Security Interest.

(a) The Security Interest granted by Borrower shall at all times be valid, perfected and enforceable against Borrower and all third parties in accordance with the terms of this Agreement, as security for the Obligations, and the Collateral shall not be at any time subject to any Liens that are prior to, or on parity with or junior to the Security Interest, other than Permitted Liens or as may be provided in the DIP Order.

(b) Borrower shall, at its sole cost and expense, take all action that may be necessary or desirable, or that Lender may reasonably request, so as at all times to maintain the validity, perfection, enforceability and rank of the Security Interest in the Collateral in conformity with the requirements of Section 3.2(a), or to enable Lender to exercise or enforce its rights hereunder.

(c) Borrower covenants and agrees with Lender that from and after the Agreement Date and until the Termination Date, at any time upon the request of Lender, Borrower shall execute (or cause to be executed) and deliver to Lender, any and all financing statements, original financing statements in lieu of continuation statements, fixture filings, security agreements, pledges, assignments, endorsements of certificates of title, and all other documents (the “Additional Documents”) upon which Borrower’s signature may be required that Lender may request in its discretion, in form and substance satisfactory to Lender, to perfect and continue the perfection of or better perfect Lender’s Liens in the Collateral (whether now owned or hereafter arising or acquired), and in order to consummate fully all of the transactions contemplated hereby and under the other Loan Documents. To the maximum extent permitted by Applicable Law, Borrower authorizes Lender to execute any such Additional Documents in Borrower’s name and authorizes Lender to file such executed Additional Documents in any appropriate filing office. Borrower authorizes Lender to transmit, communicate or, as applicable, file any financing statement under the UCC, record, in-lieu financing

statement, amendment, correction statement, continuation statement, termination statement or other instrument describing the Collateral as defined herein, as “all personal property of Debtor” or “all assets of Debtor” or words of similar effect in such jurisdictions and in such filing offices as Lender may deem necessary or desirable in order to perfect any security interest granted by Borrower under this Agreement and the other Loan Documents without signature. Borrower hereby ratifies, to the extent necessary, Lender’s authorization to file a financing statement if such financing statement has been pre-filed by Lender prior to the Agreement Date. Prior to repayment in full and final discharge of the Obligations, Borrower shall not terminate, amend or file a correction statement with respect to any financing statement filed pursuant to this Section 3.2(c) without Lender’s prior written consent.

(d) Borrower shall promptly notify Lender in writing upon incurring or otherwise obtaining a commercial tort claim, as that term is defined in the UCC, after the date hereof against any third party and, upon request of Lender, promptly amend Schedule 1 to this Agreement, authorize the filing of additional or amendments to existing financing statements and do such other acts or things deemed necessary or desirable by Lender to give Lender a security interest in any such commercial tort claim.

(e) Borrower shall xxxx its books and records as directed by Lender and as may be necessary or appropriate to evidence, protect and perfect the Security Interest and shall cause its financial statements to reflect the Security Interest.

(f) Lender shall not be required to file any UCC-1 financing statements, mortgages or any other document, or take any other action (including possession of any of the Collateral) in order to validate or perfect the liens and security interests granted to Lender hereunder or under any of the other Loan Documents, as all such Liens and security interests shall be deemed automatically perfected as of the date of the DIP Order. If Lender shall, in its discretion, choose to file such UCC-1 financing statements (or amendments to or continuations of any existing financing statements), mortgages and otherwise confirm perfection of such Liens, all such financing statements, mortgages or similar instruments shall be deemed to have been filed or recorded at the time and on the date of entry of the DIP Order. Lender may, in its discretion, file a certified copy of the DIP Order in any filing or recording office in any jurisdiction in which the Borrower (a) has or maintains any Collateral; (b) has or maintains an office; or (c) is organized.

3.3 Liens Under DIP Order. The Liens and security interests granted to Lender pursuant to the provisions of this Agreement and pursuant to any of the other Loan Documents shall be in addition to all Liens conferred upon Lender by the Bankruptcy Court pursuant to the terms of the DIP Order. Anything contained in this Agreement or any other Loan Document to the contrary notwithstanding, except for the sale of the Excluded Collateral or except as otherwise specifically permitted herein, the Borrower has no authority, express or implied, to dispose of any item or portion of the Collateral.

3.4 Priority of Liens; Further Assistance. Except as otherwise provided herein or in the DIP Order, the PRB Funding Order, the Liens granted pursuant to the terms of

this Agreement and the other Loan Documents, and the Liens conferred upon Lender pursuant of the DIP Order, secure the payment of all principal, interest, fees, expenses and all other Obligations, and shall constitute (i) pursuant to Section 364(c)(1) of the Bankruptcy Code, an allowed “super-priority” administrative expense claim except as provided in the DIP Order or in the Interim PRB Funding Order, (ii) pursuant to Section 364(c)(2) of the Bankruptcy Code, an allowed first priority Lien upon or security interest in all of the Collateral that is not otherwise encumbered by a validly perfected security interest or Lien in existence on the Petition Date that has not been primed including the DIP Facility; (iii) pursuant to Section 364(d)(1) of the Bankruptcy Code, an allowed first priority, priming Lien upon or security interest in all of the Collateral in existence on the Petition Date and the proceeds thereof except for the Permitted Liens; and (iv) pursuant to Section 364(c)(3) of the Bankruptcy Code, an allowed second priority Lien upon or security interest in all of the Collateral that was in existence on the Petition Date and subject to a validly perfected and unavoidable security interest or Lien that has not been primed.

3.5 Priority of Liens on DIP Facility Account. Notwithstanding any term or provision of this Agreement to the contrary, Lender shall have control over the DIP Facility Account and Lender’s Liens shall be higher in priority than any other Lien, including, but not limited to, any Permitted Lien, with all other Liens subordinate in priority to Lender’s Lien on the DIP Facility Account.

3.6 Waiver of Surcharge. Borrower hereby irrevocably waives any and all right to surcharge the Collateral, whether under Section 506(c) of the Bankruptcy Code or under any other Applicable Law.

In the event of dispute under this provision, the Borrower and the committee shall and hereby do consent to an expedited hearing on three (3) days’ notice.

9.2 Lender’s Remedies. In addition to any other rights and remedies that Lender may have, whether under state, Federal or local law or by virtue of any agreement between Borrower and Lender, upon the occurrence and during the continuance of an Event of Default, Lender may:

(a) Without notice to, or demand upon, Borrower:

(i) discontinue making any further Loans;

(ii) terminate this Agreement;

(iii) declare all Obligations to be immediately due and payable, whereupon the principal of the Loans together with accrued interest thereon and all other Obligations of Borrower accrued hereunder and under any other Loan Document, shall become forthwith due and payable, without presentment, demand, protest or any other notice of any kind, all of which are hereby expressly waived by Borrower, anything contained herein or in any other Loan Document to the contrary notwithstanding;

(iv) take possession of and sweep any and all funds located in the DIP Facility Account; and

(v) renew, modify or extend any Receivable, grant waivers or indulgences with respect to any Receivable, accept partial payments on

any Receivable, release, surrender or substitute any security for payment of any Receivable, or compromise with, or release, any party liable on any Receivable in such a manner as Lender may, in its sole discretion deem advisable, all without affecting or diminishing Borrower’s Obligations to Lender.

(b) With ten (10) days notice to Borrower, which notice shall be filed with the Bankruptcy Court:

(i) require Borrower, at Borrower’s expense, to assemble the Collateral and make the Collateral available to Lender at locations reasonably convenient to Lender and Borrower;

(ii) take possession of all or any portion of the Collateral, wherever located, and enter on any of the premises where any of the Collateral may be and remove, repair and store any of the Collateral until it is sold or otherwise disposed of (Lender shall have the right to store, without charge, all or any portion of the Collateral at any of Borrower’s business locations); and/or

(iii) sell or otherwise dispose of all or any portion of the Collateral at public or private sale for cash or credit, with such notice as may be required by law (in the absence of any contrary requirement, Borrower agrees that ten (10) days prior notice of a public or private sale of the Collateral is reasonable), in lots or in bulk, all as Lender, in its sole discretion, may deem advisable. Lender shall have the right to conduct any such sales, without charge, at Borrower’s business locations. Lender may purchase all or any portion of the Collateral at public sale and, if permitted by law, at private sale and, in lieu of actual payment of the purchase price, may offset the amount of such price against the outstanding amount of the Loans and any other amounts owing from Borrower to Lender. Proceeds realized from the sale of any Collateral will be applied in the following order: (A) to the reasonable costs, expenses and attorneys’ fees incurred by Lender in connection with the collection, acquisition, protection and sale of the Collateral; (B) to any accrued and unpaid interest owing from Borrower to Lender; and (C) to any other amounts owing from Borrower to Lender. Borrower agrees that Borrower will remain fully liable for any deficiency owing to Lender after the proceeds of the Collateral have been applied to the Loans and all other amounts owing from Borrower to Lender.

(c) If any of the Collateral shall require repair, maintenance, preparation, or the like, or is in process or other unfinished state, Lender shall have the right, but not the obligation, to repair or perform such maintenance, preparation, processing or completion of manufacturing to place the same in such saleable condition as Lender shall deem appropriate, but Lender shall have the right to sell or dispose of such Collateral with or without such processing.

(d) If, following the entry of the DIP Order, an Event of Default has occurred and is continuing, Borrower hereby irrevocably waives any right it may have to use cash collateral under Section 363 of the Bankruptcy Code without Lender’s written consent.

(e) Subject to the terms and condition set forth herein and in the DIP Order, the Borrower hereby waives application of the automatic stay to Lender and, as to Lender, any of the Collateral so that Lender may exercise any and/or all of it remedies hereunder or under Applicable Law.

(f) After the occurrence of any Event of Default, and irrespective of any cure period, upon the request of Lender, Borrower shall engage a Chief Restructuring Officer or other restructuring specialist (“CRO”) reasonably acceptable to Lender. The CRO will report to Borrower’s Chief Executive Officer and/or Chief Operating Officer. Any such retention shall be subject to approval by the Court after notice to creditors and parties in interest.

(g) Each and every right, power and remedy hereby specifically given to Lender shall be in addition to every other right power and remedy specifically given under this Agreement, the other Loan Documents, the DIP Order or now or hereafter existing at law or in equity, or by statute and each and every right, power and remedy whether specifically herein given or otherwise existing may be exercised from time to time or simultaneously and as often and in such order as may be deemed expedient by Lender. All such rights, powers and remedies shall be cumulative and the exercise or the beginning of exercise of one shall not be deemed a waiver of the right to exercise of any other or others. No delay or omission of Lender in the exercise of any such right, power or remedy and no renewal or extension of any of the Obligations shall impair any such right, power or remedy or shall be construed to be a waiver of any Default or Event of Default or an acquiescence therein. In the event that Lender shall bring any suit to enforce any of its rights hereunder and shall be entitled to judgment, then, in such suit, Lender may recover reasonable expenses, including attorney fees, and the amounts thereof shall be included in such judgment.

(h) In case Lender shall have instituted any proceeding to enforce any right, power or remedy under this Agreement by foreclosure, sale, entry or otherwise, and such proceeding shall have been discontinued or abandoned for any reason or shall have been determined adversely to Lender, then, and in every such case, Borrower and Lender shall be restored to their former positions and rights hereunder with respect to the Collateral subject to the Liens granted under this Agreement and the DIP Order, and all rights, remedies and powers of Lender shall continue as if no such proceeding had been instituted.

ARTICLE X - JURY TRIAL WAIVER; OTHER WAIVERS AND CONSENTS; AND GOVERNING LAW

10.1 Governing Law; Choice of Forum; Service of Process; Jury Trial Waiver.

(a) The provisions of this Agreement shall be governed by and construed in accordance with the laws of the State of Colorado, without reference to applicable conflict of law principals.

(b) Borrower and Lender irrevocably consent to the nonexclusive jurisdiction of the Bankruptcy Court, to the nonexclusive jurisdiction of the state courts of Colorado and to the nonexclusive jurisdiction of the United States District Court for the District of Colorado if the Bankruptcy Case is dismissed or relief from the Automatic Stay is obtained for the purpose of any suit, action or other proceeding arising out of or based upon this Agreement or any of the Loan Documents or the subject matter hereof.

(c) Borrower and Lender waive, to the extent not prohibited by applicable law that cannot be waived, and agree not to assert, by way of motion, as a defense or otherwise, in any such proceeding brought in any of the above-named courts, any claim that it is not subject personally to the jurisdiction of such court, that its property is exempt or immune from attachment or execution, that such proceeding is brought in an inconvenient forum, that the venue of such proceeding is improper, or that this Agreement or any of the Loan Documents, or the subject matter hereof or thereof, may not be enforced in or by such court.

(d) Borrower and Lender consent to service of process in any such proceeding in any manner at the time permitted by the Bankruptcy Code or the laws of the State of Colorado and agree that service of process by registered or certified mail, return receipt requested, at its address specified herein is reasonably calculated to give actual notice.

In any such litigation, Lender shall be entitled to the benefit of the rebuttable presumption that it acted at all times in good faith and with the exercise of ordinary care in the performance by it of the terms of this Agreement.

10.2 Waiver of Claims and Counterclaims. In no event shall Lender have any liability to Borrower for lost profits or other special, consequential, incidental, exemplary or punitive damages in connection with this Agreement or any of the other Loan Documents or the transactions contemplated hereby or thereby, and Borrower expressly waives any and all right to assert any such claims.

interpose any claims, deductions, setoffs, recoupment, or counterclaims of any nature (other than compulsory counterclaims) in any action or proceeding with respect to this Agreement, the Obligations, the Collateral or any matter arising therefrom or relating hereto or thereto; including, but not limited to those claims and causes of action referenced in Section 6.8. No officer of Lender has any authority to waive, condition, or modify the provisions of this section.

10.3 Indemnification. Borrower agrees to indemnify, save and hold harmless Lender and all other Lender Released Parties from and against: (i) the use or contemplated use of the proceeds of any of the Loans, any transaction contemplated by this Agreement or the other Loan Documents; (ii) any administrative or investigative proceeding by any governmental agency arising out of or related to a claim, demand, action or cause of action described in clause (i) above; and (iii) any and all liabilities, losses, costs or expenses (including reasonable attorneys’ fees and disbursements and other professional services) that any party indemnified hereunder suffers or incurs as a result of any foregoing claim, demand, action or cause of action; provided, however, that no such indemnitee shall be entitled to indemnification for any loss caused by its own willful misconduct.

10.4 Waiver of Marshalling Rights. Borrower waives any right of marshalling of assets of Borrower, including without limitation, any such right with respect to the Collateral.

ARTICLE XI - MISCELLANEOUS

11.1 Power of Attorney. Borrower irrevocably appoints Lender, and any person designated by Lender, as Borrower’s true and lawful attorney-in-fact to: (a) endorse for Borrower, in Lender’s or Borrower’s name, any draft or other order for the payment of money payable to Borrower; and (b) execute and file or submit for recording, in Lender’s or Borrower’s name, Financing Statements describing the Collateral. Lender shall not be liable to Borrower for any action taken by Lender or its designee under this power of attorney, except to the extent that such action was taken by Lender in bad faith or with willful misconduct. Borrower agrees that a carbon, photographic, electronic or other reproduction of a Financing Statement or this Agreement may be filed by Lender as a Financing Statement.

11.2 Outstanding Loan Balance. The outstanding principal amount of, and accrued interest on, the Loans and the Interest Rate applicable to the Loans from time to time, shall be, at all times, ascertained from the records of Lender and shall be conclusive absent manifest error.

11.3 Modifications and Course of Dealing. This Agreement constitutes the entire agreement of Borrower and Lender relative to the subject matter hereof and supersedes in their entirety any prior agreements or understandings, whether written or oral, pertaining to the subject matter hereof. No modification of or supplement to this Agreement shall bind Lender unless in writing and signed by an authorized officer of

Lender. The enumeration in this Agreement of Lender’s rights and remedies is not intended to be exclusive, and such rights and remedies are in addition to and not by way of limitation of any other rights or remedies that Lender may have under the Uniform Commercial Code or other Applicable Law. No course of dealing and no delay or failure of Lender to exercise any right, power or privilege under any of the Loan Documents will affect any other or future exercise of such right, power or privilege. The exercise of any one right, power or privilege shall not preclude the exercise of any others, all of which shall be cumulative.

11.4 Assignment and Participation. Borrower may not assign or transfer any of its rights or delegate any of its obligations under this Agreement or any of the other Loan Documents. Lender shall have the right, from time to time, without notice to Borrower, to sell, assign or otherwise transfer all or any part of its interest in this Agreement, the other Loan Documents, and the Loans to any other party, or enter into participation arrangements with any other party. Borrower authorizes Lender to deliver to potential assignees or participants Borrower’s financial information and all other information delivered to Lender in furtherance of or pursuant to the terms of this Agreement.

11.5 Delegation of Duties. Lender may execute any of its duties under this Agreement or the other Loan Document by or through agents, employees or attorneys-in-fact. Lender shall not be responsible for the negligence or misconduct of any agent or attorney-in-fact selected by Lender as long as such selection was made in good faith.

11.6 Notices. Except as otherwise provided herein, whenever any notice, demand, request or other communication shall or may be given to or served upon any party by any other party, or whenever any party desires to give or serve upon any other party any communication with respect to this Agreement, each such communication shall be in writing and shall be deemed to have been validly served, given or delivered (a) upon the earlier of actual receipt and five (5) Business Days after deposit in the United States mail, registered or certified mail, return receipt requested, with proper postage prepaid, (b) upon transmission, when sent by telecopy or other similar facsimile transmission (with such telecopy or facsimile promptly confirmed by delivery of a copy by personal delivery or United States mail as otherwise provided in this Section 11.6), (c) one (1) Business Day after deposit with a reputable overnight courier with all charges prepaid or (d) when hand-delivered, all of which shall be addressed to the party to be notified and sent to the address or facsimile number indicated in the signature page to this Agreement or to such other address (or facsimile number) as may be substituted by the giving of notice of such substitution. Delivery of a copy of any notice under this Section 11.6 to an individual designated on the signature page as “with a copy to” shall not be deemed notice to a party.

11.7 Payment of Expenses and Taxes. Borrower agrees (a) to pay or reimburse Lender for all its out-of-pocket costs and expenses reasonably incurred in connection with the preparation and execution of, any amendment, supplement or modification to, and the enforcement or preservation of any rights under, this Agreement, the other Loan Documents, and the DIP Order, and the consummation of the transactions contemplated hereby and thereby, including, without limitation the reasonable fees and disbursements of counsel to Lender and other professionals engaged by Lender, (b) to pay or reimburse

Lender for all its costs and expenses reasonably incurred in connection with the enforcement or preservation of any rights under this Agreement, the other Loan Documents, the DIP Order and any such other documents following the occurrence and during the continuance of a Default or an Event of Default, including, without limitation, the reasonable fees and disbursements of counsel to Lender and other professionals engaged by Lender, (c) to pay, and indemnify and hold harmless Lender from, any and all recording and filing fees and any and all liabilities with respect to, or resulting from any delay in paying, stamp, excise and other taxes, if any, which may be payable or determined to be payable in connection with the execution and delivery of, or consummation or administration of any of the transactions contemplated by, or any amendment, supplement or modification of, or any waiver or consent under or in respect of, this Agreement, the other Loan Documents, the DIP Order and any such other documents, (d) to pay, and indemnify and hold harmless Lender (and its directors, officers, employees and agents) from and against any and all other liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever with respect to the execution, delivery, enforcement, performance, preservation of rights and administration of this Agreement, the other Loan Documents, the DIP Order or the use of the proceeds of the Loans (all the foregoing in this clause (d), collectively, the “Indemnified Liabilities”), provided, that Borrowers shall have no obligation hereunder to Lender with respect to Indemnified Liabilities determined by the final judgment of a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of Lender or its directors, officers, employees or agents. The agreements in this Section 11.7 shall survive repayment of the Loans and all other Obligations payable hereunder.

11.8 Binding Effect; Severability. This Agreement shall not be deemed to create any right in any party except as provided herein and shall inure to the benefit of, and be binding upon, the successors and assigns of Borrower and Lender. All of Borrower’s obligations under this Agreement are absolute and unconditional and shall not be subject to any offset or deduction whatsoever. The provisions of this Agreement are intended to be severable. If any provision of this Agreement is held invalid or unenforceable in whole or in part, such provision will be ineffective to the extent of such invalidity or unenforceability without in any manner effecting the validity or enforceability of the remaining provisions of this Agreement.

11.9 Final Agreement. This Agreement and the other Loan Documents are intended by Borrower and Lender to be the final, complete, and exclusive expression of the agreement between them, except as may be provided in the DIP Order. This Agreement supersedes any and all prior oral or written agreements relating to the subject matter hereof. No modification, rescission, waiver, release, or amendment of any provision of this Agreement or any provision of any of the other Loan Documents shall be made, except by a written agreement signed by Borrower and a duly authorized officer of Lender.

11.10 Counterparts. This Agreement may be executed in any number of counterparts, and by Lender and Borrower in separate counterparts, each of which shall be an original, but all of which shall taken together constitute one and the same

agreement. The parties hereby acknowledge and agree that facsimile signatures of this Agreement shall have the same force and effect as original signatures.

11.11 Captions. The captions contained in this Agreement are for convenience of reference only, are without substantive meaning and should not be construed to modify, enlarge, or restrict any provision.

11.12 Right of Set-off. Subject to the giving of the notice as described in Article 9, notwithstanding the provisions of Section 362 of the Bankruptcy Code, and any other rights and remedies of Lender now or hereafter granted under applicable law or otherwise, and not by way of limitation of any such rights, upon the occurrence and during the continuance of any Event of Default, Lender is hereby authorized at any time or from time to time, without presentment, demand, protest or other notice of any kind to Borrower or to any other Person, any such notice being hereby expressly waived, to set-off any other indebtedness or other obligation at any time held or owing by Lender to or for the credit or the account of any Borrower against and on account of the Obligations of Borrower to Lender under this Agreement or under any of the other Loan Documents, and all other claims of any nature or description arising out of or connected with this Agreement or any other Loan Document, irrespective of whether or not Lender shall have made any demand hereunder and although said Obligations, liabilities or claims, or any of them, shall be contingent or unmatured.

11.13 Maximum Lawful Rate. Notwithstanding any provision of this Agreement or the other Loan Documents to the contrary, it is the intent of Lender and Borrower, that neither Lender nor any successor or assign shall be entitled to receive, collect, reserve or apply, as interest, any amount in excess of the amount determined by application of the Maximum Lawful Rate of Interest. In the event this Agreement or the other Loan Documents calls for an interest payment that exceeds the amount determined by application of the Maximum Lawful Rate of Interest, such interest shall not be received, collected, charged or reserved until such time as that interest together with all other interest then payable, falls within the amount determined by application of the Maximum Lawful Rate of Interest. In the event Lender receives any such interest in excess of the amount determined by the application of the Maximum Lawful Rate of Interest, such amount which would be excessive interest shall be deemed a partial prepayment of principal and treated hereunder as such, or, if the principal indebtedness is paid in full, any remaining excess funds shall immediately be paid to Borrower. In determining whether or not the interest paid or payable, under any specific contingency, exceeds the amount determined by application of the Maximum Lawful Rate of Interest, Borrower and Lender shall, to the greatest extent permitted under applicable law, (a) exclude voluntary prepayments and the effects thereof, and (b) amortize, prorate, allocate, and spread, in equal parts, the total amount of interest throughout the entire term of the indebtedness; provided, however, that if the indebtedness is paid in full then to the end of the full contemplated term hereof; and if the interest received for the actual period of existence hereof exceeds the amount determined by application of the applicable Maximum Lawful Rate of Interest, Lender shall refund to Borrower the amount of such excess or credit the amount of such excess against the principal portion of the indebtedness as of the date it was received, and, in such event, Lender shall not be subject to any penalties provided by any laws for contracting for, charging, reserving, collecting

or receiving interest in excess of the amount determined by the application of the applicable Maximum Lawful Rate of Interest.

11.14 Limitation of Liability. No claim may be made by Borrower or any other entity against Lender or any of its affiliates, lenders, investors, directors, officers, employees, attorneys or agents for any special, indirect, consequential or punitive damages in respect of any claim for breach of contract or any other theory of liability arising out of or related to the transactions contemplated by this Agreement or any act, omission or event occurring in connection herewith; and Borrower hereby waives, releases and agrees not to xxx upon any claim for any such damages, whether or not accrued and whether or not known or suspected to exist in its favor.

11.15 DIP Order Controls. This Agreement and the other Loan Documents are each subject to the terms and provisions contained in the DIP Order to the same extent and effect as if the DIP Order were fully set forth herein and therein; and in the event that any term or provision of this Agreement or any other Loan Document conflicts or is inconsistent with any term or provision of any DIP Order, the term and provision of the applicable DIP Order shall control and be given effect.

11.16 Bankruptcy Court Approval. This Agreement and Borrower’s and Lender’s obligations and duties hereunder is expressly conditioned upon approval by the Bankruptcy Court and entry of the DIP Order.
