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.

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.

excess interest charges paid by Borrower to Lender shall be applied to reduce the outstanding principal balance of the Obligations.

(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.

1.6 Priority of All Advances and Loans All advances and loans, including, but not limited to, all fees, interest, and expenses, and any other portion of the Obligations, whether such Obligations are within or in excess of the Maximum Total Amount, made hereunder by Lender to Borrower shall constitute and be deemed an allowed cost and expense of administration in the Bankruptcy Case and shall be entitled to priority under Section 364(c)(1), Section 364(c)(2), Section 364(c)(3), and Section 364(d) of the Bankruptcy Code ahead of all other costs and expenses of administration of the kind specified in Sections 105, 326, 330, 331, 503(b), 506(c), 507(a), 507(b) or 726 of the Bankruptcy Code, except as may be otherwise provided in the DIP Order or pursuant to the Corrected Interim Order Authorizing Post-Petition Financing and Use of Cash Collateral dated April 11, 2008 (Docket No. 154) (the “Interim PRB Funding Order”); provided, however, that the Lender’s Liens, other than its Lien upon the DIP Facility Account, shall be subordinate in priority to the Permitted Liens.

All fees, whether such fees are within or in excess of the Maximum Total Amount, incurred hereunder shall constitute and be deemed an allowed cost and expense of administration in the Bankruptcy Case and shall be entitled to priority under Section 364(c)(1), Section 364(c)(2), Section 364(c)(3), and Section 364(d) of the Bankruptcy Code ahead of all other costs and expenses of administration of the kind specified in Sections 105, 326, 330, 331, 503(b), 506(c), 507(a), 507(b) or 726 of the Bankruptcy Code, except as may be otherwise provided in the DIP Order or the Interim PRB Funding Order; provided, however, that the Lender’s Liens, other than its Lien upon the DIP Facility Account, shall be subordinate in priority to the Permitted Liens.

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.

ARTICLE IV - PLAN OF REORGANIZATION AND EXIT FINANCING

4.1 Exclusivity Agreement. Borrower acknowledges that, to induce Lender to enter into this Agreement and establish the DIP Facility, it will pursue the formulation of the Plan of Reorganization with Lender, and/or its assigns, and in furtherance thereof, shall:

(a) During the Exclusivity Period, and as long as Lender makes the advances required by the DIP Facility on and subject to the terms of this Agreement and continues to negotiate with Borrower in good faith on the terms of the Exit Financing and the Plan of Reorganization, then, in consideration thereof, Borrower shall deal and negotiate exclusively with the Lender with respect to the Exit Financing and the Plan of Reorganization, except as otherwise provided herein.

(b) For a period of no less than forty-five (45) days following the Agreement Date, Lender shall have the right to conduct due diligence and evaluate Borrower and its business and to decide whether to enter into definitive agreements with respect to the Exit Financing; provided, however, that if Lender

decides not to enter into definitive agreements with respect to the Exit Financing, Lender shall continue to provide the DIP Facility on and subject to its terms, except as otherwise provided herein. Lender shall not be obligated to enter into a definitive agreement with respect to the Exit Financing during such time or at any time and any determination not to enter into any such definitive agreement shall be in Lender’s sole and absolute discretion without penalty of any kind.

(c) Until the earlier of (x) the date, if any, on which Lender notifies Borrower in writing that Lender has elected not to proceed with the evaluation of the Exit Financing and (y) forty-five (45) days from the Agreement Date (the “Exclusivity Period”), Borrower will not, directly or indirectly (including through any affiliate, attorney, representative, employee, officer, director, shareholder, partner, member, trustee, agent or any other person acting on its behalf or at its direction): (i) effectuate or negotiate or have any discussions with any other party, or solicit, encourage, induce or facilitate the making of any offer, or accept any offer from, any other party concerning (A) any exit financing or plan of reorganization, (B) any acquisition of all or substantially all of Borrower’s outstanding securities or assets (excluding the Excluded Assets), (C) any merger, consolidation, reorganization or other extraordinary business transaction with any other person or entity, or (D) any issuance, redemption, conversion, recapitalization or exchange of any securities of Borrower or authorization or designation any new securities of Borrower; (ii) provide to any other person any information concerning Borrower, its assets or business (other than to the extent that such information is publicly available through or as directed to be made available by the Bankruptcy Court, or is required pursuant to any order previously entered by the Bankruptcy Court in the Bankruptcy Case or otherwise, or as routinely provided to such other persons in the ordinary course of business consistent with past practice, so long as Borrower has no reason to believe such information may be utilized to evaluate a possible transaction of the type described in this Article IV); provided, however, that Borrower may provide such information to the Official Committee of Unsecured Creditors (the “Committee”) in the Bankruptcy Case, subject to the terms of a written confidentiality agreement signed by each member of the Committee and the Committee’s professionals; (iii) amend or waive, or consent to or approve (whether through action or inaction), any amendment, waiver or other action under, any terms or conditions of any of the agreements or instruments governing the Debentures or those certain 10% Senior Subordinated Convertible Notes (the “Convertible Notes”), or the rights of the holders of the Debentures (the “Debenture Holders”) or the holders of Convertible Notes (the “Convertible Noteholders”) thereunder, respectively, or seek the consent or waiver of the Debentures Holders or the Convertible Noteholders, without the prior written consent of Lender; or (iv) any agreement, commitment or understanding to do any of the foregoing. Without limiting the foregoing, during the Exclusivity Period, Borrower will work exclusively with Lender to formulate definitive Exit Financing and Plan of Reorganization and facilitate Lender’s due diligence investigation of Borrower’s assets and operations.

(d) If Borrower receives any unsolicited proposal or offer (whether written or oral) relating to an exit financing transaction, a plan of reorganization, or any related transaction or series of transactions (each, an “Offer”), Borrower shall (i) transmit each Offer (including a written copy thereof, if applicable) to Lender within twenty-four (24) hours of the receipt thereof (the “Offer Delivery Period”) and, (ii) within three Business Days following the time during the Offer Delivery Period when an Offer is delivered to Lender (such three (3) Business Days, the “Evaluation Period”), communicate to Lender whether Borrower, following consideration of any applicable fiduciary duty, will proceed with such Offer or reject such Offer.

(e) Borrower agrees to provide to Lender any and all materials, information, and documentation submitted to the Committee or any other party by or on behalf of Borrower, not later than twenty-four (24) hours following submission of such materials, information or documentation that relates to Borrower (the “Information Access Requirement”).

(f) The Exclusivity Period may be extended beyond the forty-five (45) day period set forth above for up to an additional thirty (30) days by mutual written agreement of Lender and Borrower (the “Exclusivity Extension”).

4.2 Plan of Reorganization.

(a) Borrower agrees to use its best efforts to have a Plan of Reorganization, as contemplated herein and in a form and substance acceptable to Lender in its sole and absolute discretion, confirmed by the Bankruptcy Court as soon as practicable, provided, that it shall be a condition precedent to, among other things, the provision of the Exit Financing that the effective date of the Plan of Reorganization (the “Plan Date”) shall not be later than August 31, 2008, unless otherwise extended by Lender in writing; provided, however, that in the event of an Exclusivity Extension, the Plan Date shall be not later than September 30, 2008.

(b) Borrower and Lender agree that the Plan of Reorganization would provide that assets to be included in the entity exiting the Bankruptcy Case as contemplated herein (the “Reorganized Debtor”) shall include, without limitation, all of the DJ Basin Collateral, including any assets related thereto, or used in connection therewith, as of the Agreement Date. The Plan of Reorganization would provide further that all of the Excluded Assets, or the proceeds from the sale thereof, would be excluded and would be transferred to a liquidating trust for the benefit of the allowed unsecured claims asserted against Energy.

(c) The Plan of Reorganization would provide, among other things, the granting of releases of any and all claims that any party in interest in the Bankruptcy Case has or may have against Borrower, Lender, or the Reorganized Debtor, which releases would be in form and substance satisfactory to Borrower and Lender.

(d) The Plan of Reorganization would provide an amount sufficient to pay or provide terms otherwise sufficient to satisfy the allowed claims of the Debentures Holders in full either on the Plan Date or as may otherwise be determined by Lender.

(e) The Plan of Reorganization would provide an amount sufficient to pay or provide terms otherwise sufficient to satisfy the allowed secured claims of PRB Funding, LLC (in the principal amount of up to $575,000.00) and all allowed mechanics’ liens on Oil & Gas’ assets in full as of the Plan Date, which are estimated to be $86,000 in the aggregate, or on such other terms as the respective parties may agree.

(f) The Plan of Reorganization would provide that the Reorganized Debtor would pay or otherwise satisfy in full all allowed administrative and other unsecured priority claims due and owing by Oil & Gas in respect of Oil & Gas’ assets as of the Plan Date, in an amount to be determined by Lender (the “Administrative Claims Maximum”).

(g) Following the execution of this Agreement, Borrower will promptly file a motion to set a Chapter 11 administrative claims bar date (the “Administrative Claims Bar Date”) and obtain an Order of the Bankruptcy Court setting the Administrative Claims Bar Date, provided that the Administrative Claims Bar Date shall occur not fewer than forty-five (45) days prior to the first hearing with respect to the confirmation of the Plan of Reorganization.

(h) The Reorganized Debtor shall attempt to assume those executory contracts and unexpired leases as determined by Lender, and such executory contracts and unexpired leases shall vest in the Reorganized Debtor. Any cure payments relating to the assumption of those executory contracts and unexpired leases will be funded or paid by the Reorganized Debtor and shall not be counted against the Administrative Claims Maximum.

(i) The Plan of Reorganization would provide that the principal amount of all allowed unsecured trade claims, other than inter-company claims, all of which Borrower will waive as part of the Plan of Reorganization, asserted against Oil & Gas would be paid or otherwise satisfied in full by the Reorganized Debtor in the amount of 33-1/3 % of the allowed amount of the trade claim per year over a three (3) year period following the Plan Date; provided, that the allowed amount of each trade claim shall not exceed the amount outstanding on the Pre-Petition claims bar date.

(j) The Plan of Reorganization will provide that Lender will receive 87.5% of the equity in the Reorganized Debtor, and the remaining 12.5% of the equity would be reserved for Energy and other stakeholders (such 12.5%, the “Minority Interest”). The restrictions to be placed on the Minority Interest will include, without limitation, the following: (i) the Minority Interest will be held by a single entity, which may be in the form of a liquidating trust; (ii) the Minority

Interest in the Reorganized Debtor will have no voting rights; and, among other things, (iii) the Minority Interest in the Reorganized Debtor will not be entitled to participate in any management decisions involving the Reorganized Debtor.

(k) The Reorganized Debtor would work in good faith to develop and formulate a key employee incentive plan for the benefit of the employees of Oil & Gas and Energy that the Reorganized Debtor employs after the consummation of the transactions contemplated herein. All holders of equity interests in the Reorganized Debtor shall be diluted on a pro-rata basis to provide equity interests in the Reorganized Debtor to employees of Oil & Gas and/or Energy under this incentive plan; provided, that such equity interests granted to such employees shall consist of common equity with no voting rights.

4.3 Exit Financing. The Exit Financing to be provided by Lender is subject to completion of items to be set forth in the Plan of Reorganization and would include, without limitation, the following material terms:

(a) The Exit Financing would be in an amount sufficient to pay or provide terms otherwise sufficient to satisfy the allowed claims of the Debentures Holders in full either on the Plan Date or as may otherwise be determined by Lender.

(b) The amount of the Exit Financing would be sufficient to pay or provide terms otherwise sufficient to satisfy the allowed secured claims of PRB Funding, LLC (in the principal amount of up to $575,000.00) and all mechanics’ liens on the Oil & Gas’ assets in full as of the Plan Date, which are estimated to be $86,000 in the aggregate, or on such other terms as the respective parties may agree.

(c) The Exit Financing would also be in an amount sufficient to provide the Reorganized Debtor with a commitment to fund up to $10,000,000.00 for operations and drilling, which amount would be disbursed pursuant to agreed-upon operating budgets and drilling plans.

(d) There shall have been no Material Adverse Effect to the business, operations or prospects of Oil & Gas or Energy (except for any change due to the liquidation of the Excluded Assets).

(e) Lender shall be entitled to determine, in its reasonable discretion, the amount of the Exit Financing that would be invested as equity capital and the amount intended to constitute debt capital under the capital structure of the Reorganized Debtor.

4.4 Liquidated Damages. The Exit Financing would further provide for the approval of a commitment fee for the Exit Financing of $300,000.00 (the “Exit Financing Commitment Fee”), earned as of the filing of the Exit Financing with the Court, and payable upon closing and funding of the Exit Financing or as provided below. If,

subsequent to Lender and Borrower submitting a Plan of Reorganization to the Bankruptcy Court for approval, the transactions contemplated thereby are not consummated (other than as a result of the failure of the Bankruptcy Court to approve the Plan of Reorganization or a material breach by Lender) because either (A) Borrower is in material breach of or default under any provision of the Plan of Reorganization or the related agreements and such material breach or default (if and to the extent such breach or default is capable of being cured by Borrower) is not cured within ten (10) days, or (B) Borrower enters into any financing or other arrangement with one or more third parties, then there shall be due by Borrower to Lender (i) the Exit Financing Commitment Fee plus liquidated damages of $500,000.00 (the “Liquidated Damages”). Such amounts due shall be treated as an allowed super priority administrative expense claim (such super priority claim shall be junior to super priority claims allowed by the Court prior to the date of this Agreement) upon the termination of any applicable cure period or non-waiver by Lender of any such breach or default, or the consummation of such third party transaction, as the case may be. Payment shall be made upon the consummation of any third-party transaction or as further ordered by the Bankruptcy Court. Such allowed super priority administrative expense claim shall be considered to be genuine pre-estimate of Lender’s liquidated damages to compensate Lender for its direct and indirect costs of negotiating with Debtors and is not considered a penalty. Except as otherwise set forth above, if Lender elects to not proceed with the Exit Financing according to the terms set forth herein, then Lender shall not be entitled to the Exit Financing Commitment Fee or the Liquidated Damages. Lender shall provide to Borrower a detailed proposal of the Exit Financing on or before July 7, 2008. Borrower shall file a motion with the Bankruptcy Court seeking approval of the Exit Financing within forty-eight (48) hours after receipt of the Exit Financing proposal that is consistent with the terms contemplated in this Article 4. Borrower shall obtain Bankruptcy Court approval of the Exit Financing Commitment Fee and the Liquidated Damages prior to July 31, 2008, with any failure to obtain such approval constituting an Event of Default.

(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

(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;

(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.

(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.

The provisions of this Agreement are intended to be severable.

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.
