AGREEMENT AND PLAN OF MERGER

This Agreement and Plan of Merger, dated as of February 20, 2007 (this "Agreement"), is made by and among The Exploration Company of Delaware, Inc., a Delaware corporation ("Parent"), Output Acquisition Corp., a Texas corporation and a wholly-owned Subsidiary of Parent ("Sub"), and Output Exploration, LLC, a Delaware limited liability company (the "Company"). Parent, Sub and the Company are each a "party" and together are "parties" to this Agreement. Capitalized terms used herein are defined or cross-referenced in Section 11.3 of this Agreement. The Stakeholders' Representative, upon appointment, shall also enter into and deliver this Agreement.

W I T N E S S E T H

WHEREAS, the Boards of Directors of Parent and Sub and the Board of Representatives of the Company have each approved the merger of the Company with and into Sub (the "Merger"), upon the terms and subject to the conditions set forth in this Agreement, whereby the issued and outstanding units of the membership interests of the Company (excluding units owned, directly or indirectly, by the Company or any Subsidiary of the Company or by Parent, Sub or any other Subsidiary of Parent, which units will be canceled and retired without payment of any consideration) will be canceled and retired and converted into the right to receive the Merger Consideration;

WHEREAS, Parent, Sub, and the Company desire to prescribe various conditions to the Merger; and

WHEREAS, the holders of Company Units representing a majority of the issued and outstanding Company Units entitled to vote on the Merger have, by written consent in lieu of a special meeting of the holders of Company Units entitled to vote thereon, approved the Merger and the terms and conditions of this Agreement;

NOW, THEREFORE, in consideration of the representations, warranties, covenants and agreements contained in this Agreement, the parties agree as follows:

ARTICLE I

THE MERGER

Section 1.1 The Merger. Upon the terms and subject to the conditions set forth in this Agreement, and in accordance with the Delaware General Corporation Law (the "DGCL") and the Delaware Limited Liability Company Act (the "DLLCA"), the Company shall be merged with and into Sub at the Effective Time. Upon the Effective Time, the separate existence of the Company shall cease, and Sub shall continue as the surviving corporation in the Merger (the "Surviving Corporation").

- 1 -

Section 1.2 Closing. Unless this Agreement shall have been terminated and the transactions herein contemplated shall have been abandoned pursuant to Article IX and subject to the satisfaction or waiver of the conditions set forth in Article VI, the closing of the Merger (the "Closing") shall take place at 10:00 a.m. on the second business day following the date on which the last of the conditions to be fulfilled or waived set forth in Article VI shall be fulfilled or waived in accordance with this Agreement (the "Closing Date"), at the offices of Xxxxxx and Xxxxx, LLP, legal counsel to the Company, located at 0000 XxXxxxxx Xxxxxx, Xxxxx 0000, Xxxxxxx, Xxxxx 00000, unless another date, time or place is agreed to in writing by the parties hereto; provided, however, that it is acknowledged and agreed that the Closing Date shall be extended to April 2, 2007 to the extent required for Parent to arrange for its financing for the transactions contemplated by this Agreement despite all conditions to Closing having previously been fulfilled or waived. The Closing may, with the consent of all parties thereto, take place by delivering an exchange of documents by facsimile transmission or electronic mail with originals to follow by overnight mail service or courier.

Section 1.3 Effective Time. The parties hereto shall file with the Secretary of State of the State of Delaware (the "Delaware Secretary of State") on the Closing Date (or on such other date as Parent and the Company may agree) a certificate of merger (the "Certificate of Merger") and/or other appropriate documents, executed in accordance with the relevant provisions of the DGCL and the DLLCA, and make all other filings or recordings required under the DGCL or the DLLCA in connection with the Merger. The Merger shall become effective upon the filing of the Certificate of Merger with the Delaware Secretary of State, or at such later time as is specified in the Certificate of Merger (the "Effective Time").

Section 1.4 Effects of the Merger. The Merger shall have the effects set forth in the DGCL and the DLLCA. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time, all the properties, rights, privileges, powers and franchises of the Company and Sub shall vest in the Surviving Corporation, and all debts, liabilities and duties of the Company and Sub shall be and become the debts, liabilities and duties of the Surviving Corporation. For income Tax purposes, the Merger will be treated as (i) a sale of assets by the Company to Sub in exchange for the Merger Consideration and Sub's assumption of the Company's liabilities immediately followed by (ii) a complete liquidation of the Company. The parties hereto will characterize the Merger as such for purposes of all income Tax Returns.

Section 1.5 Certificate of Incorporation; Bylaws. The Certificate of Incorporation of Sub, as in effect immediately prior to the Effective Time, and as set forth on Exhibit A attached hereto, shall be the Certificate of Incorporation of the Surviving Corporation until amended in accordance with applicable law. The Bylaws of Sub as in effect immediately prior to the Effective Time, and as set forth on Exhibit B attached hereto, shall be the Bylaws of the Surviving Corporation until amended in accordance with applicable law.

Section 1.6 Directors. The directors of Sub immediately prior to the Effective Time shall become the directors of the Surviving Corporation at and as of the Effective Time (retaining their respective terms of office).

- 2 -

Section 1.7 Officers. The officers of Sub immediately prior to the Effective Time shall become the officers of the Surviving Corporation at and as of the Effective Time (retaining their respective positions and terms of office).

EFFECT OF THE MERGER ON THE SECURITIES OF THE

CONSTITUENT COMPANIES

Section 2.1 Effect of the Merger. As of the Effective Time, by virtue of the Merger and without any further action on the part of the holders of any membership units of the Company (the "Company Units") or of the holders of any shares of capital stock of Sub:

(a) Shares of Sub. Each share of capital stock of Sub issued and outstanding immediately prior to the Effective Time shall be converted into one fully-paid and non-assessable share of common stock of the Surviving Corporation.

(b) Cancellation of Treasury Stock and Parent-Owned Capital Stock. All Company Units issued and outstanding immediately prior to the Effective Time that are owned by the Company or by any Subsidiary of the Company or by Parent, Sub or any other Subsidiary of Parent shall automatically be canceled and retired and shall cease to exist, and no cash or other consideration shall be delivered or deliverable in exchange therefor.

(c) Company Units. Other than Company Units to be canceled and retired without any consideration being delivered therefor as provided in Section 2.1(b), each Company Unit issued and outstanding immediately prior to the Effective Time (the "Converting Units") shall automatically be converted into and become (i) a right to receive an amount, in immediately available funds, equal to the aggregate amount in the Payment Fund divided by the number of Converting Units together with the number of Unit Equivalents, as shown on Exhibit 2.2 plus (ii) a contingent right to receive a portion of each distribution, if any, from the Expense Account and the Reserve Account to the holders of Converting Units pursuant to Section 2.4(g), Section 2.4(h) and Section 2.6(d), as applicable, with such portion to equal the amount of such distribution divided by the number of Converting Units together with the number of Unit Equivalents, as shown on Exhibit 2.2 (such right in clause (i) and such contingent right in clause (ii) referred to collectively as the "Merger Consideration").

(d) Cancellation and Retirement of Company Units. As of the Effective Time, all Company Units issued and outstanding immediately prior to the Effective Time shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and each holder of any such Company Units shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration upon delivery of a Letter of Transmittal in accordance with Section 2.5.

- 3 -

(e) Warrants and Options. The Company shall take such action in order that, prior to the Effective Time, all warrants issued by the Company, whether then exercisable (the "Warrants"), and all options granted by the Company, including without limitation those granted under any Company option plan or agreement (collectively, as such plans or agreements may have been amended, supplemented or modified from time to time, the "Option Plans"), that are unexercised, whether then exercisable (the "Options"), shall have been extinguished and those Warrants and Options that are "in-the-money" shall be converted into a right to receive an amount in cash equal to their appropriate share of the Merger Consideration as provided in Section 2.2, reduced by the exercise price of that respective Option or Warrant, and that the holders of Warrants and Options shall have no other rights with respect thereto. All Options, Warrants and all Option Plans shall be terminated as of the Effective Time.

Section 2.2 Stakeholders. At the Effective Time, all Warrants and Options and all rights under Contingent Payment Agreements and Earn Out Agreements will be converted, based upon cashless exercise principles and the terms of such instruments, into an economic equivalent number of Converting Units ("Unit Equivalents"), as reflected, with the holders of Converting Units, on Exhibit 2.2. Holders of Converting Units and the holders of Unit Equivalents are collectively referred to as the "Stakeholders." Stakeholders will be entitled to an appropriate share of the Merger Consideration, distributions from the Expense Account pursuant to Section 2.4(g) and Section 2.4(h), distributions from the Reserve Account pursuant to Section 2.6(d) and distributions of the Restructuring Transactions proceeds other than Moon Bend Proceeds on the basis reflected in Exhibit 2.2.

Section 2.3 Rights. The Company shall, prior to the Effective Time, (a) ensure that all restrictions on the transfer of Company Units and Unit Equivalents under the Certificate of Formation of the Company (the "Certificate of Formation"), the Limited Liability Company Agreement of the Company (the "Investors Agreement") and any other contract, agreement, arrangement or understanding to which the Company is a party or by which it, the Company Units or Unit Equivalents are bound shall not apply to the Merger or the other transactions contemplated by this Agreement and (b) solicit from each beneficiary of the Contingent Payment Agreements and the Earn Out Agreements written agreement, in the form of Exhibit 2.3 (which exhibit shall be attached to this Agreement by mutual agreement of Parent and the Company no later than five (5) business days after the date of this Agreement) (each, a "Holders' Agreement"), that the consideration to be provided to such beneficiary pursuant to this Agreement shall be the sole and exclusive consideration to which such beneficiary is entitled pursuant thereto, that each such Contingent Payment Agreement and Earn Out Agreement shall at all times after the Effective Time represent only the right to receive the portion of the Merger Consideration to which such beneficiary is entitled pursuant to this Agreement and that each such Contingent Payment Agreement and Earn Out Agreement shall, for all other purposes, be deemed terminated and of no further force and effect following the Effective Time.

Section 2.4 Funding Obligations and Certain Disbursements.

(a) Deposit. Parent shall deposit, or shall cause to be deposited, the sum of Two Million Dollars ($2,000,000) with the Escrow Agent by check, wire transfer or other form of immediately available or same day funds upon execution and delivery of this Agreement.

The Escrow Agent shall hold the amounts deposited with the Escrow Agent hereunder in escrow in an interest-bearing account pursuant to the terms of an escrow agreement executed by Parent, the Company, and the Escrow Agent as of the date hereof in the form materially similar to that set forth in Exhibit 2.4(a) hereto (the "Deposit Escrow Agreement").

(i) deposit, or shall cause to be deposited, into an escrow account with the Reserve Agent intended to comply with exemptions under applicable federal and state securities laws (the "Reserve Account"), a stock certificate or certificates, issued in the name of the Reserve Agent for the further benefit of the Stakeholders' Representative, representing a number of fully-paid, non-assessable, validly authorized and issued shares of common stock, par value $0.01 per share, of Parent ("Parent Common") equal in number to $4,000,000 divided by the Deal Stock Price with any fractional share disregarded (the shares of Parent common stock deposited into the Reserve Account are referred to herein as the "Reserve Shares");

(iv) deposit, or shall cause to be deposited, into a segregated expense account (the "Expense Account") with the Paying Agent, an amount in cash (the "Expense Deposit") equal to (A) the aggregate amount of Deferred Adjustment Claims, plus (B) the amount of the Employee Retention Bonuses, and plus (C) the amount of Sellers' Expenses set forth in a notice delivered to Parent at least two (2) business days prior to Closing (the "Sellers' Expenses Allowance"); and

- 6 -

(e) Disbursement of Sellers' Expenses. At Closing, the Paying Agent shall pay from the Expense Account, to each payee of Sellers' Expenses, the amount due that payee (in an aggregate amount not to exceed the Sellers' Expenses Allowance) as the Stakeholders' Representative may direct.

(f) Disbursement of Employee Retention Bonuses. Following the Closing, when authorized by the joint written instructions of Parent and the Stakeholders' Representative, the Paying Agent shall pay, from the Expense Account, to each employee of the Company set forth on Exhibit D of this Agreement, the amount of the employee retention bonus listed on such schedule adjacent to such employee's name (the "Employee Retention Bonuses"). Prior to Closing, the Company will extinguish all accrued and unused vacation and sick time for employees accrued during all periods (or portions thereof) prior to January 1, 2007. The Surviving Corporation shall be responsible for all other employment matters and expenses incurred by the Company in the Ordinary Course of Business that are attributable to all periods (or portions thereof) following December 31, 2006, including without limitation unused vacation and sick time accrued after December 31, 2006 by any employee of the Company who is not retained by the Surviving Corporation.

From time to time following the Closing upon the settlement of any Deferred Adjustment Claim, as set forth in the joint written instructions of Parent and the Stakeholders' Representative or in a final, non-appealable order by a court of competent jurisdiction delivered to the Paying Agent by Parent or the Stakeholders' Representative, the Paying Agent shall pay, from the Expense Account, (i) to Parent, the amount of such settled Deferred Adjustment Claim to which Parent is entitled, if any, and (ii) to the Stakeholders, the amount of such settled Deferred Adjustment Claim to which Parent is not entitled, if any. All distributions to the Stakeholders pursuant to this Section 2.4(g) shall be allocated among such Stakeholders as provided in Exhibit 2.2.

(h) Termination of Expense Account. Following the final resolution of all Deferred Adjustment Claims and payment of all Sellers' Expenses and the Employee Retention Bonuses, any monies remaining in the Expense Account shall be distributed to the Stakeholders, and the Expense Account shall thereafter be terminated. All distributions to the Stakeholders pursuant to this Section 2.4(h) shall be allocated among such Stakeholders as provided in Exhibit 2.2.

(i) Investment of Funds. The Paying Agent will invest all cash included in the Payment Fund and the Expense Account, as applicable, through the Escrow Agent in short term United States government securities or comparable investments; provided, however, that the terms and conditions of the investments shall be such as to permit the Paying Agent to make prompt payment of such amounts as required hereunder. All earnings of the Payment Fund and the Expense Account shall be deposited into the Expense Account.

(j) Paying Agent Expenses. The Expense Account shall be governed by a Distribution Agreement, by and among the Paying Agent, Parent and the Stakeholders' Representative in the form materially similar to that set forth in Exhibit 2.4(j) hereto (the "Expense Escrow Agreement"). In accordance with the terms of the Expense Escrow Agreement, the reasonable charges and expenses of the Paying Agent in connection with the Expense Account shall be (i) paid one-half by Parent and Sub from their own accounts and (ii) paid one-half by the Stakeholders' Representative (including, to the extent available, from the Expense Account).

- 7 -

Following the Closing, in accordance with the procedures set forth on Exhibit 2.4(k) attached hereto, the parties will verify that the calculations of the California Net Profit or Loss used for adjustments to the Merger Consideration at Closing pursuant to Section 2.12(a) were accurate. To the extent of any inaccuracy, Parent will make a corrective payment to the Expense Account or Parent will be entitled to the release of Reserve Shares from the Reserve Account, as the case may be, as further provided for in Exhibit 2.4(k).

Section 2.5 Exchange Procedures.

(a) Letter of Transmittal. The Payment Fund shall be governed by a Distribution Agreement, by and between the Paying Agent and the Stakeholders' Representative in form and substance satisfactory to each of such parties. Promptly after the Effective Time (but in no event more than five (5) days thereafter), the Paying Agent will mail to each Stakeholder a form of letter of transmittal ("Letter of Transmittal") and instructions for use in surrendering Converting Units, Options, Warrants, Earn Out Agreements and Contingent Payment Agreements and receiving the Merger Consideration to which such Stakeholder shall be entitled therefor. By execution and delivery of a Letter of Transmittal, a Stakeholder shall be deemed to consent to the terms of the Merger and this Agreement, including the appointment of the Stakeholders' Representative pursuant to Section 2.7.

(b) Paying Agent Procedures. The Paying Agent will distribute from the Payment Fund to each Stakeholder, upon delivery to the Paying Agent of a Letter of Transmittal and acceptance thereof by the Paying Agent, each such Stakeholder's appropriate share of the Payment Fund as provided in Exhibit 2.2. The Paying Agent shall accept Letters of Transmittal upon compliance with such reasonable terms and conditions as the Paying Agent may impose to effect an orderly exchange thereof in accordance with normal exchange practices. If the Merger Consideration (or any portion thereof, including any payments from the Expense Account or the Reserve Account in accordance with Section 2.4(g), Section 2.4(h) or Section 2.6(d), as applicable) is to be delivered to any person other than the Stakeholder in whose name the Converting Units, Options, Warrants, Earn Out Agreements or Contingent Payment Agreements surrendered in exchange therefor is registered, it shall be a condition to such exchange that a duly executed and witnessed instrument of transfer shall be properly endorsed or otherwise be in proper form for transfer and that the person requesting such exchange shall pay to the Paying Agent any transfer or other Taxes required by reason of the payment of such consideration to a person other than the registered Stakeholder thereof, or shall establish to the satisfaction of the Paying Agent that such Tax has been paid or is not applicable. After the Effective Time, there shall be no further transfer on the records of the Company or its transfer agent of Converting Units or Unit Equivalents and if Converting Units or Unit Equivalents are presented to the Company for transfer, they shall be canceled against delivery of the Merger Consideration as herein provided. Until surrendered as contemplated by this Section 2.5(b), Converting Units and Unit Equivalents shall be deemed at all times after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration, as contemplated by Section 2.1(c), Section 2.1(e) and Section 2.2.

- 8 -

(c) No Further Ownership Rights. The Merger Consideration paid upon the surrender of Converting Units or Unit Equivalents in accordance with the terms of this Article II (including the contingent right to receive a portion of all distributions to the holders of Converting Units or Unit Equivalents from the Expense Account or the Reserve Account in accordance with Section 2.4(g), Section 2.4(h) or Section 2.6(d), as applicable) shall be deemed to be paid in full satisfaction of all rights pertaining to the Converting Units or Unit Equivalents.

(d) Withholding Rights. Each of the Reserve Agent and the Paying Agent shall be entitled to deduct and withhold from the Merger Consideration otherwise payable pursuant to this Agreement to any Stakeholder such amounts as the Reserve Agent and the Paying Agent are required to deduct and withhold with respect to the making of such payment under the Code or any provision of state, local or foreign Tax law. To the extent such amounts are so withheld by the Reserve Agent or the Paying Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Stakeholder in respect of whom such deduction and withholding was made.

(e) No Liability. Neither Parent, Sub, the Surviving Corporation nor the Paying Agent shall be liable to any person in respect of any distributions payable from the Payment Fund or Expense Account delivered to a public official pursuant to any applicable abandoned property, escheat or similar law.

Section 2.6 Reserve Account. The Reserve Account shall be governed by an Escrow Agreement, by and among the Reserve Agent, Parent and the Stakeholders' Representative in the form materially similar to that set forth in Exhibit 2.6 hereto (the "Reserve Escrow Agreement").

(a) Payments after Closing. From time to time following the Closing, in accordance with the terms of the Reserve Escrow Agreement, the Reserve Agent shall, upon the joint written instructions of Parent and the Stakeholders' Representative (which instructions shall not be unreasonably withheld, conditioned or delayed by Parent or the Stakeholders' Representative following notice from the Reserve Agent of a claim made against the Reserve Account) or the delivery by Parent of a final, non-appealable order by a court of competent jurisdiction, that Parent or any other Parent Indemnitee is entitled to an amount pursuant to Article X (the "Indemnity Amount"), release to Parent or such other Parent Indemnitee such number of Reserve Shares as may equal the Indemnity Amount divided by the Deal Stock Price, disregarding any fractional share. Parent shall cooperate with the Reserve Agent in exchanging any certificate representing Reserve Shares for such number of certificates, representing the like number of aggregate Reserve Shares, and in such denominations as the Reserve Agent may require to release Reserve Shares as and when required pursuant to this Section 2.6(a).

(b) Reserve Agent Expenses. In accordance with the terms of the Reserve Escrow Agreement, the reasonable charges and expenses of the Reserve Agent shall be (i) paid one-half by Parent and Sub from their own accounts and (ii) paid one-half by the Stakeholders' Representative (including, to the extent available, from the Expense Account).

(c) Liquidation of Reserve Shares. At the close of business twelve (12) months after the Effective Time, the Reserve Agent will arrange the sale for cash of an aggregate number of Reserve Shares, disregarding any fractional share, equal to (i) the number of Reserve Shares then held in the

- 9 -

Reserve Account, minus (ii) the number of Reserve Shares obtained by dividing the aggregate dollar amount of all pending but unsettled and unpaid claims made by Parent Indemnitees pursuant to Article X by the Deal Stock Price, minus (iii) number of Reserve Shares obtained by dividing the aggregate dollar amount of all settled but unpaid claims made by Parent Indemnitees pursuant to Article X by the Deal Stock Price (such pending and unpaid settled claims, the "Outstanding Claims"). As soon as practicable following the final resolution and payment of all Outstanding Claims, including the release to Parent Indemnitees of all Reserve Shares required to satisfy any obligation owing to them in respect of the Outstanding Claims pursuant to Article X, the Reserve Agent will arrange the sale for cash of the remaining Reserve Shares held in the Reserve Account. All sales of Reserve Shares by the Reserve Agent shall be subject to the requirements of applicable law. The sale of the Reserve Shares by the Reserve Agent shall be made in daily amounts not to exceed 20% of the average daily trading volume of Parent Common on the Nasdaq Global Select Market for the prior ten trading days, unless the Reserve Agent is jointly instructed otherwise by the Stakeholders' Representative and Parent.

(d) Distribution to Stakeholders; Termination of Reserve Account. As soon as practicable following any sale of Reserve Shares pursuant to Section 2.6(c), the Reserve Agent shall distribute the cash proceeds thereof, less costs of sale, to the Stakeholders. All distributions pursuant to this Section 2.6(d) shall be allocated among such Stakeholders as provided in Exhibit 2.2. Upon the final distribution of such proceeds, the Reserve Account shall be terminated.

Section 2.7 Appointment of Stakeholders' Representative. Prior to the Effective Time, the Company's Board of Representatives will constitute and appoint a person with full power of substitution and resubstitution, to act as the agent, representative and attorney-in-fact of any and all of the Stakeholders and in their name, place and xxxxx (the "Stakeholders' Representative") with respect to any matter arising in connection with this Agreement and to make on behalf of any or all such holders, individually and collectively, any decisions and take all actions that they would be entitled to make pursuant to this Agreement (but for the appointment of the Stakeholders' Representative), including any decision, action, notice, or election taken with respect to the indemnification rights and obligations of such holders pursuant to Article X and any other decision, action, notice or election that may prejudice the rights of any such holder or may have an adverse effect with respect to any such holder.

Section 2.8 Title and Environmental Defects.

(a) Access. Through and including March 26, 2007 (the "Examination Period"), the Company shall permit, to the extent that the Company has the ability to grant access, Parent and its representatives to have reasonable access to the properties and assets of the Company and its Subsidiaries for the purpose of allowing Parent to inspect the properties and assets and conduct due diligence (including Phase I and Phase II Environmental Site Assessments) for any Environmental Defects, all at Parent's sole risk, cost and expense. The Company or its representatives shall have the right to be present during any such inspection of the properties and assets. All such inspections by Parent shall be conducted in such a manner as to cause the least possible interference with the operations of the Company, and after any such inspections, the subject properties and assets shall be restored as nearly as possible to their condition prior to such inspections, at Parent's sole cost and expense. Prior to accessing the properties or the assets, Parent shall provide 24 hours prior notice to the Company of the properties or assets to be accessed and during such 24 hour period the parties will mutually agree on the scope of the investigation to be conducted on such properties or assets, which agreement by the Company shall not be unreasonably withheld. Parent shall indemnify, defend and hold harmless the Company and its Subsidiaries for any Losses or Claims asserted against them arising from the acts or omissions of Parent or its agents, contractors or employees in conducting conducing any due diligence on the properties or assets pursuant to this Section 2.8(a). In addition, Parent will remove any investigation-derived wastes within thirty (30) days of its generation and will be designated as the generator of such wastes for the purposes of waste disposal, if permitted under applicable Environmental Laws. Parent will provide to the Company and its Subsidiaries copies of the final draft reports relating to any such inspections.

(b) Parent's Assertion of Defects. Prior to the end of the Examination Period (the "Defect Notice Date"), Parent shall notify the Company in writing of any matters which, in Parent's reasonable opinion, constitute Environmental Defects or Title Defects (collectively, "Defects") and which Parent intends to assert as a Defect with respect to any portion of the Company's Ownership Interests pursuant to this Section 2.8. Those Defects identified in such notice to the Company are herein called "Asserted Defects." Parent shall be deemed to have waived any Defect that Parent fails to raise as an Asserted Defect by written notice given to the Company on or before the Defect Notice Date, except that if (i) a non-asserted Defect constitutes a breach of the representations and warranties of the Company set forth in this Agreement and (ii) as of the Defect Notice Date, Parent either (A) does not have actual knowledge of the facts necessary to establish all of the material elements of such breach or (B) does not have actual knowledge that the facts known by Parent constitute such breach, then such non-asserted Defect may be asserted by Parent following the Effective Time as a claim for indemnification under Article X to the extent that such non-asserted Defect constitutes a breach of the representation or warranties of the Company set forth in this Agreement. To be effective, Parent's written notice of an Asserted Defect must include (1) a brief description of the matter constituting the Asserted Defect, (2) the estimated claimed Losses attributable thereto, and (3) supporting documents reasonably necessary to verify the existence of such Asserted Defect. The Merger Consideration attributable to any particular Ownership Interest for purposes of the Asserted Defect procedures shall be the values allocated to each such Ownership Interest on Exhibit 2.8 attached hereto (the "Allocated Merger Consideration Values"). Parent shall promptly furnish the Company with written notice of any matter or circumstance which increases the Company's interest in any Ownership Interest and which is discovered by any of Parent's employees or representatives while conducting Parent's title review, due diligence or investigation with respect to the Ownership Interests. Parent shall instruct all employees and representatives of Parent conducting due diligence on the Ownership Interests to report any interest in an Ownership Interest that is additional to those set forth in Exhibit 3.2.

- 11 -

(c) Company Cure. If Parent notifies the Company of any Asserted Defect on or before the Defect Notice Date, the Company shall have the right, at its sole discretion (and without obligation) and at its cost and expense, until two (2) business days prior to Closing, to cure all or a portion of the Asserted Defect. If the Company fails to cure an Asserted Defect within such time period, and Parent does not waive the Asserted Defect on or before the Closing, the Ownership Interest affected by such Asserted Defect shall be deemed a "Defective Property."

(d) Merger Consideration Adjustments.

(i) If Parent presents an Asserted Defect to the Company in accordance with Section 2.8(b) and the Company is unwilling or unable to cure such Asserted Defect as of two (2) business days prior to Closing, the Company shall have the option to transfer the Defective Property to which such Asserted Defect relates together with pipelines and other personal property necessary to operate the respective Defective Property (collectively, the "Excluded Property") to the Designated Entity. To exercise such option, the Company must provide Parent with written notice thereof (including a complete listing of the Excluded Property and the Allocated Merger Consideration Value attributable thereto) at any time prior to Closing. Upon receipt of such notice, Parent shall have the right to withdraw the Asserted Defect to which such notice relates, in which case the Company's exercise of the option to transfer the Excluded Property shall be null and void and no adjustment to the Merger Consideration shall be made with respect to such Asserted Defect. If the Company exercises this option and Parent does not withdraw such Asserted Defect, (A) the respective Excluded Property shall be conveyed to the Designated Entity immediately prior to the Closing without warranty of title, either express or implied, (B) the Merger Consideration shall be reduced by the Allocated Merger Consideration Value attributable to all such Excluded Property, pursuant to Section 2.4(c)(iv)(A), and (C) Parent, the Designated Entity and the Company shall enter into a mutually-agreeable arrangement for the sharing of any Excluded Property that is necessary for the Surviving Corporation to be able to conduct the business conducted by the Company as of the Effective Time in the Ordinary Course of Business.

(ii) If (A) Parent presents an Asserted Defect to the Company in accordance with Section 2.8(b), (B) the Company is unwilling or unable to cure such Asserted Defect as of two (2) business days prior to Closing, (C) the Company does not elect to transfer such Defective Property to the Designated Entity pursuant to Section 2.8(d)(i) and (D) the parties agree on the amount of the corresponding reduction of the Merger Consideration attributable to such Asserted Defect prior to two (2) business days prior to the Closing, then the Merger Consideration shall be reduced by such agreed-upon amount, pursuant to Section 2.4(c)(iv)(A).

- 12 -

(iii) Notwithstanding anything to the contrary herein, if the aggregate sum of the reductions in Merger Consideration pursuant to this Section 2.8(d) does not exceed $975,000 (the "Asserted Defect Threshold"), then no such adjustments shall be made with respect to the Merger Consideration. If the sum of the adjustments to be made pursuant to this Section 2.8(d) does exceed the Asserted Defect Threshold, then the Merger Consideration shall be reduced accordingly, inclusive of the portion equal to the Asserted Defect Threshold.

Section 2.9 Definition of Defects.

(a) Environmental Defects. For purposes of this Agreement, the term "Environmental Defect" shall mean an existing condition or circumstance with respect to the air, soil, subsurface, surface waters, groundwater, and/or sediments that causes, or upon notice or passage of time or both would cause, (i) an asset or property of the Company or its Subsidiaries to not be in compliance with any Environmental Law, including any Permits issued thereunder, or (ii) such asset or property to be required to be remediated (or other corrective action taken with respect to such asset or property) under any Environmental Law. The term "Environmental Defect" shall also mean and include any situation or circumstance regarding an Ownership Interest that would constitute a breach or violation of the Company's representations and warranties given in Section 3.1(n) (disregarding all "Knowledge of the Company" qualifiers in such representations and warranties for purposes of determining whether such a breach or violation has occurred). Notwithstanding any other provision in this Agreement to the contrary, the presence of "NORM" (Naturally Occurring Radioactive Material) that is attached to the inside of xxxxx, materials, and equipment as scale or in other forms shall not be asserted as, and shall not constitute, Environmental Defects, although the presence of NORM in soils, surface water or groundwater may constitute an Environmental Defect if its presence is as a result of the activities of the Company or its Subsidiaries, and the presence of such is regulated under applicable Environmental Laws and/or the presence of such is prohibited under the terms of any lease for such asset or property. To the extent that an Environmental Defect involves contamination or a requirement for remediation, investigation, or corrective action, such Environmental Defect shall be remediated to achieve the most cost-effective remediation standard permitted under applicable Environmental Laws, unless the lease for such asset or property requires contamination to be remediated to a more stringent standard, in which case that standard shall apply to the remediation.

(b) Title Defects. For purposes of this Agreement, the term "Title Defect" shall mean any of the following:

(i) the Company does not have Defensible Title to an Ownership Interest;

(ii) any royalties, overriding royalties, rentals, Xxxx clause payments, shut-in gas payments and other payments due with respect to an Ownership Interest have not been properly and timely paid by or on behalf of the Company, except for payments held in suspense for title or other reasons which are customary in the industry and which will not result in grounds for cancellation of the Company's rights in such Ownership Interest;

(iii) the Company is in default under the terms of any Material Contract which could (A) prevent the Company from receiving the proceeds of production attributable to the Company's interest therein, or (B) result in cancellation of the Company's interest therein; or

- 13 -

(iv) any situation or circumstance regarding an Ownership Interest that would constitute a breach or violation of the Company's representations and warranties given in Section 3.2(a).

Section 2.10 Deferred Claims and Disputes. If (a) Parent presents an Asserted Defect to the Company in accordance with Section 2.8(b), (b) the Company is unwilling or unable to cure such Asserted Defect as of two (2) business days prior to Closing, (c) the Company does not elect to transfer such Defective Property to the Designated Entity pursuant to Section 2.8(d)(i) and (d) the parties do not agree on a corresponding reduction of the Merger Consideration attributable to such Asserted Defect prior to two (2) business days prior to the Closing, then Parent's claim to a reduction of the Merger Consideration in respect of such Asserted Defect (a "Deferred Adjustment Claim") shall be settled pursuant to this Section 2.10 and shall not prevent or delay the Closing. With respect to each potential Deferred Adjustment Claim, Parent and the Company shall deliver to the other promptly a written notice describing each such potential Deferred Adjustment Claim, the amount in dispute and a statement setting forth the facts and circumstances that support such party's position with respect to such Deferred Adjustment Claim. At the Closing, the Merger Consideration shall not be adjusted on account of, and, except as provided in Section 6.1(c), no effect shall be given to, the Deferred Adjustment Claim. On or prior to the thirtieth (30^th) day following the Closing (the "Deferred Matters Date"), the Company and Parent shall attempt in good faith to reach agreement on the Deferred Adjustment Claims and, ultimately, to resolve by written agreement all disputes regarding the Deferred Adjustment Claims. Any Deferred Adjustment Claims that are not so resolved on or before the Deferred Matters Date may be submitted by either party to final and binding arbitration in accordance with Section 2.11; provided, however, that the Stakeholders' Representative may elect at any time to resolve any disputes relating to such Deferred Adjustment Claim by authorizing payment to Parent of the amount by which the Merger Consideration would have been reduced at Closing on account of the Asserted Defects which constitute Deferred Adjustment Claims if the same did not constitute Deferred Adjustment Claims. Notwithstanding anything herein provided to the contrary, including Section 2.8(c), the Company shall be entitled to cure any Asserted Defect which constitutes a Deferred Adjustment Claim relating to a Title Defect (but not Deferred Adjustment Claims relating to an Environmental Defect) at any time prior to the time when a final and binding written decision of the arbitrators is made with respect thereto. The amount of any reduction in the Merger Consideration shall be promptly paid to Parent from the Expense Account pursuant to Section 2.4(g).

- 14 -

Section 2.11 Arbitration. Deferred Adjustment Claims unresolved on the Deferred Matters Date and submitted by a party to arbitration pursuant to this Section 2.11 shall be submitted to binding arbitration in Houston, Xxxxxx County, Texas, under the auspices of, and pursuant to the rules of, the American Arbitration Association's Commercial Arbitration Rules as then in effect, or such other procedures as the parties may agree to at the time, before a tribunal of three (3) arbitrators, one of which shall be selected by Parent, one of which shall be selected by the Stakeholders' Representative, and the third of which shall be selected by the two (2) arbitrators so selected. Any award issued as a result of such arbitration shall be final and binding between the parties, and shall be enforceable by any court having jurisdiction over the party against whom enforcement is sought. A ruling by the arbitrators shall be non-appealable. The parties agree to abide by and perform any award rendered by the arbitrators. If either Parent or the Stakeholders' Representative seeks enforcement of the terms of this Agreement or seeks enforcement of any award rendered by the arbitrators, then the prevailing party (designated by the arbitrators) to such proceeding(s) shall be entitled to recover its costs and expenses from the non-prevailing party, in addition to any other relief to which it may be entitled. If one party fails or refuses to designate an arbitrator within thirty (30) days after receipt of a written notice that an arbitration proceeding is to be held, then the dispute shall be resolved solely by the arbitrator designated by the other party and such arbitration award shall be as binding as if three (3) arbitrators had participated in the arbitration proceeding. Parent and the Stakeholders' Representative covenant and agree to act as expeditiously as practicable in order to complete arbitration. The arbitration proceeding shall be held in English. Arbitration under this Section 2.11 must be concluded and a final award given within one hundred twenty (120) days following Closing.

Section 2.12 Adjustments. The amount of the Merger Consideration shall be adjusted, as provided in Section 2.4(c)(v)(A), as set forth below:

(a) the Merger Consideration shall be increased or decreased, as the case may be, by the amount of the California Net Profit or Loss;

(b) the Merger Consideration shall be decreased by the amount of capital expenditures paid by the Companies between September 30, 2006 and the Closing with respect to the Oil and Gas Interests of the Companies and related properties in the State of California (the "California Assets");

(c) the Merger Consideration shall be decreased by the amount by which any capital expenditure, paid by the Companies without the prior approval of Parent, between September 30, 2006 and the Closing (other than with respect to the California Assets) exceeds the amount permitted therefor by the mutually agreed upon Capital Expenditure Budget attached hereto as Exhibit 2.12(c) (the "Capital Expenditure Budget") (capital expenditures identified by the Company after the signing of this Agreement and before Closing, and approved by the Parent, will be added to the Capital Expenditure Budget);

(d) the Merger Consideration shall be decreased by the amount of any payments made by the Companies to any Related Parties, and any liabilities to any Related Parties incurred by the Companies, between September 30, 2006 and the Closing (other than the distribution of the net proceeds of the Restructuring Transactions, payment for the provision of engineering services by Xxxxxxxxxx & Co. to the Company and its Subsidiaries in the Ordinary Course of Business at market rates, and the payment of directors fees and employee compensation in the Ordinary Course of Business);

(e) the Merger Consideration shall be decreased by the amount of any payments (above and beyond salary paid during taken sick days) made by the Companies to their employees in connection with the extinguishment of all accrued and unused vacation and sick time accrued during all periods (or portions thereof) prior to January 1, 2007;

- 15 -

(f) the Merger Consideration shall be decreased by $75,000 (which represents a mutually-agreed reduction in the Merger Consideration in consideration of Parent's agreement to include a $75,000 exception amount in the last sentence of Section 3.1(h)(i)); and

(g) without duplication of any amounts otherwise deducted from the Merger Consideration in accordance with the preceding subsections of this Section 2.12, the Merger Consideration shall be decreased by the amount of any payments made by the Companies to their employees or other third parties, and any liabilities to any employees or third parties incurred by the Companies, in either case outside of the Ordinary Course of Business, between September 30, 2006 and the Closing (other than the distribution of the net proceeds of the Restructuring Transactions).

Section 2.13 Allocation. The Merger Consideration, the portion of the Expense Account that is neither included in the defined term "Merger Consideration" nor paid to Parent, the Company's liabilities assumed by Sub as a result of the Merger and all other capitalized costs (collectively, the "Consideration") shall be allocated, in a manner consistent with the Allocated Merger Consideration Values and in accordance with Section 1060 of the Code and the Treasury regulations thereunder, among the assets of the Company as of the Closing Date in accordance with a schedule mutually agreed to by Parent, Sub and the Stakeholders' Representative on or before the Closing Date, which schedule shall be attached to this Agreement as Exhibit 2.13 at or before the Closing. Any adjustments to the Consideration (including any adjustment under Section 2.4(k), Section 2.8(d) and Section 2.12) shall be reflected in such allocation in a manner consistent with such Exhibit 2.13 and Treasury Regulation §§1.1060-1(c) and 1.338-7. For all Tax purposes, Parent, Sub and the Company agree to report the transactions contemplated in this Agreement in a manner consistent with the allocation reflected in Exhibit 2.13 (as such Exhibit 2.13 is adjusted in accordance with the immediately preceding sentence), and will not take any position inconsistent therewith in any Tax Return, any proceeding before a taxing authority, or otherwise.

All proceeds from the sale of the Companies' share of the Hydrocarbons being produced from their Oil and Gas Interests are currently being paid in full to the Companies by the buyers thereof on a timely basis, and, except as noted on Exhibit 3.2, none of such proceeds are currently being held in suspense by such buyer or any other party (except for amounts, individually or in the aggregate, not in excess of $50,000 and held in suspense in the Ordinary Course of Business).

Except as otherwise set forth on Exhibit 3.2(b), all xxxxx included in the Oil and Gas Interests of the Companies have been drilled and, if completed, operated and produced in accordance with generally accepted oil and gas field practices and in compliance in all material respects with applicable oil and gas leases, pooling and unit agreements, and applicable laws, rules, regulations, judgments, orders and decrees issued by any court or Governmental Authority.

Section 5.7 Tax Covenants.

(a) Tax Returns; Allocation. The Stakeholders' Representative shall engage, at the cost and expense of the Stakeholders' Representative, the Company's certified public accounting firm to timely prepare, in a manner consistent with prior practice, all Tax Returns required to be filed by the Company and/or any of its Subsidiaries for periods ending on or before the Closing Date, including the preparation of any short-period Tax Return ending on the Closing Date; provided, however, that the Stakeholders' Representative shall provide Parent with a 15-day (or, in the case of income Tax Returns, 30-day) period prior to the filing date to review and comment on each such Tax Return prior to their filing. Parent shall cause to be prepared at its cost and expense, each Tax Return required to be filed by the Company and/or any of its Subsidiaries for each period beginning on or before the Closing Date and ending after the Closing Date and shall determine (pursuant to the last sentence of this Section 5.7(a)) the amount of Tax due with respect to the portion of such period ending on the Closing Date; provided, however, that Parent shall provide the Stakeholders' Representative with a 15-day (or, in the case of income Tax Returns, 30-day) period prior to the filing date to review and comment on each such Tax Return and determination prior to the filing of such Tax Return. Parent and the Stakeholders' Representative shall attempt in good faith to reach agreement with respect to any issue resulting from any review of a Tax Return or determination described in the foregoing provisions of this Section 5.7(a). Should Parent and the Stakeholders' Representative fail to reach such an agreement within 15 days after delivery of such Tax Return, a determination with respect to such issue shall be made by Xxxxxxx Xxxx & Xxxxxxx of Texas, P.C., whose decision shall be final and binding upon the parties. Parent shall prepare and file, or cause to be prepared and filed, all Tax Returns required to be filed by the Company and/or any of its Subsidiaries for all periods beginning after the Closing Date. Whenever it is necessary for purposes of this Agreement to determine the portion of any Taxes imposed on or incurred by the Company and/or any of its Subsidiaries for a taxable period beginning on or before and ending after the Closing Date which is allocable to the portion of such period ending on the Closing Date, the determination shall be made, in the case of property or ad valorem Taxes or franchise Taxes (which are measured by, or based solely upon, capital, debt or a combination of capital and debt), on a per diem basis and, in the case of other Taxes, by assuming that the portion of such taxable period ending on the Closing Date constitutes a separate taxable period of the Company and/or any of its Subsidiaries, as the case may be, and by taking into account the actual taxable events occurring during such portion of such taxable period ending on the Closing Date.

(b) Cooperation. The Stakeholders' Representative, on the one hand, and Parent, on the other hand, shall, and shall cause their Affiliates to, provide to each of the other parties hereto and its Affiliates such cooperation, documentation and information as any of them reasonably may request in filing any Tax Return or claim for refund, determining a liability for Taxes or a right to refund of Taxes or in conducting any audit, examination, contest, litigation or other proceeding in respect of Taxes. Such cooperation and information shall include providing copies of all relevant portions of relevant Tax Returns, together with all relevant portions of relevant accompanying schedules and relevant work papers, relevant documents relating to rulings or other determinations by taxing authorities and relevant records concerning Tax basis and other information that any such party may possess, at the requesting parties expense. The Stakeholders' Representative, Parent, Sub and their respective Affiliates shall make themselves and their employees reasonably available on a mutually convenient basis to provide explanation of any documents or information so provided.

- 45 -

(c) Post-Closing Tax Administration for Pre-Closing Periods. Except as otherwise expressly provided in this Section 5.7 and in Article X, (i) following the Closing, the Stakeholders' Representative will control the income Tax matters of the Company relating to any period or portion thereof ending on or before the Closing Date and will keep Parent informed of developments and events relating to such matters, provided that the Stakeholders' Representative will not permit any Tax action or position to be taken by the Company that could affect the Taxes of any of the Parent Indemnitees for any post-Closing period without the prior written consent of Parent (such consent not to be unreasonably withheld, conditioned or delayed) or as otherwise required by applicable law; and (ii) with the exception of Tax matters described in clause (i) of this sentence, Parent will control the Tax matters of the Companies following the Closing, provided that Parent will not permit any Tax action or position to be taken by the Companies that could affect the Taxes of the Company for any pre-Closing period without the prior written consent of the Stakeholders' Representative (such consent not to be unreasonably withheld, conditioned or delayed).

(b) Parent will make available to the Designated Entity and its accountants and other representatives, at reasonable times and upon reasonable notice (and copies thereof at the Designated Entity's sole cost and expense), the books and records of the Companies for the purpose of determining and resolving any post-closing adjustments to purchase price under the agreements entered into by the Company in connection with the California Sale, to the extent such books and records are relevant thereto;

(c) Parent will forward to the purchaser of the California Assets, as soon as practicable after receipt thereof, any payments or other amounts received by Parent or the Companies from any third party in respect of the California Assets that are attributable to periods following the closing of the California Sale and to which such purchaser is entitled under the agreements entered into by the Company in connection with the California Sale; and

(d) following the closing of the California Sale, Parent will cause the Companies to execute and deliver to the purchaser of the California Assets such further instruments of conveyance and transfer, as such purchaser may reasonably request and at such purchaser's sole cost and expense, in order to more effectively convey and transfer the California Assets to such purchaser.

Section 10.5 Notice and Resolution of Claims.

(a) Notice. A Person entitled to indemnification pursuant to Section 10.1 or Section 10.2 (an "Indemnitee") must provide reasonably prompt written notice to the party obligated to provide indemnification to such Indemnitee (the "Indemnifying Party") after obtaining knowledge of any claim that it may have pursuant to this Article X (whether for its own Losses or in connection with a Claim made by a third party (a "Third Party Claim"); provided that the failure to provide reasonably prompt notice will not limit the rights of an Indemnitee to indemnification hereunder except to the extent that such failure materially increases the dollar amount of any such claim for indemnification or materially prejudices the ability of the Indemnifying Party to defend such claim. Such notice will set forth in reasonable detail the claim and the basis for indemnification.

(b) Third Party Claims.

(i) Right to Assume Defense. With respect to a claim for indemnity that arises from a Third Party Claim, the Indemnifying Party will have thirty (30) days after receipt of notice to assume the conduct and control of the settlement or defense of such Third Party Claim, through counsel reasonably acceptable to the Indemnitee and at the expense of the Indemnifying Party. The Indemnitee may participate in such defense or settlement through its own counsel, but such separate counsel will be at its own expense unless one or more defenses, claims or counterclaims are available to the Indemnitee that conflict with one or more defenses, claims or counterclaims available to the Indemnifying Party. In no event, however, will the Indemnifying Party be liable for the fees and expenses of more than one separate counsel of the Indemnitee.

(ii) Obligations Following Assumption of Defense. If the Indemnifying Party assumes the defense of a Third Party Claim, it must take all steps necessary to investigate and defend or settle such Third Party Claim and will hold the Indemnitee harmless from and against any and all Losses caused by or arising out of any settlement approved by the Indemnifying Party or any judgment entered in connection with such Third Party Claim. Without the written consent of the Indemnitee, the Indemnifying Party will not consent to entry of any judgment or enter into any settlement that does not include an unconditional and complete release of the Indemnitee by the claimant or plaintiff making the Third Party Claim.

(iii) Failure to Assume Defense. Failure by the Indemnifying Party to notify the Indemnitee of its election to assume the defense of any Third Party Claim within thirty (30) days after its receipt of notice thereof pursuant to Section 10.5(a) will be deemed a waiver by the Indemnifying Party of its right to assume the defense of such Third Party Claim. In such event, the Indemnitee may defend against such Third Party Claim in any manner that, in good faith, it deems appropriate. The Indemnitee may settle such Third Party Claim or consent to the entry of any judgment with respect thereto, provided that it acts in good faith and in a commercially reasonable manner.

- 56 -

(c) Arbitration of Non-Third Party Claims. With respect to a claim for indemnity that does not arise from a Third Party Claim and that cannot be resolved to the mutual satisfaction of the Indemnitee and the Indemnifying Party through good faith negotiation within thirty (30) days of the giving of written notice of the claim pursuant to Section 10.5(a), either the Indemnitee or the Indemnifying Party may submit such claim and dispute to arbitration by the American Arbitration Association in Houston, Texas, United States of America under the commercial rules then in effect for that Association except as provided herein. The party submitting the claim and dispute to arbitration shall provide notice of the intent to arbitrate to the other party. All proceedings shall be held, and a transcribed record prepared, in English. Each party shall choose one (1) arbitrator within thirty (30) days of the non-submitting party's receipt of the submitting party's notice of the intent to arbitrate. Within sixty (60) days of such receipt of the notice of the intent to arbitrate, the two (2) arbitrators shall choose a neutral third arbitrator who shall act as chairman. If no arbitrator is appointed by a party, or by the two arbitrators chosen by the parties, within the times herein provided or any extension of time which is mutually agreed upon, the Association shall appoint a substitute arbitrator for the arbitrator(s) not so appointed within thirty (30) days of such failure. The award rendered by the arbitrators shall include costs of arbitration, actual attorney's fees and reasonable costs for expert and other witnesses, and judgment on such award may be entered in any court having jurisdiction thereof; provided, however, that nothing in this Section 10.5(c) shall be deemed as preventing either party from seeking equitable relief from the courts. In preparation for the arbitration hearing, each party may utilize all methods of discovery authorized by the Federal Rules of Civil Procedure, and may enforce the right to discovery in the manner provided by said Rules.

Section 10.6 Limitations of Indemnity.

(a) De Minimus Loss Requirement. An Indemnitee will not be entitled to indemnification under Section 10.1(a) or Section 10.2(a), as the case may be, with respect to any particular breach (or series of related breaches) of a representation and warranty unless the Losses for which indemnification is sought by such Indemnitee with respect to such particular breach (or series of related breaches) exceed $10,000, in which case such Indemnitee will be entitled to be indemnified for all of such Losses from the first dollar.

(b) Basket. The Parent Indemnitees will not be entitled to indemnification under Section 10.1(a) unless the aggregate amount of all Losses for which indemnification is sought by the Parent Indemnitees exceeds the Basket, in which case the Parent Indemnitees will be entitled to be indemnified for all of such Losses from the first dollar; provided, however, that the limitation set forth in this Section 10.6(b) will not be applicable to any breach by the Company of the representations and warranties set forth in Section 3.1(c) ("Capitalization") or Section 3.1(h) ("Taxes"). The "Basket" will equal $975,000 less the aggregate amount applied against the Asserted Defect Threshold pursuant to Section 2.8(d) if and only if such applied amount did not result in a reduction of the Merger Consideration (i.e., such applied amount was less than $975,000).

- 57 -

(c) Cap. The aggregate liability of the Stakeholders to provide indemnification pursuant to this Article X may not exceed $4,000,000.

(d) Reserve Account. The sole and exclusive remedy of the Parent Indemnitees for all indemnification obligations owed to the Parent Indemnitees pursuant to this Article X will be the Reserve Shares held in the Reserve Account from time to time, to the extent not previously released in accordance with this Agreement. In no event will the Parent Indemnitees have recourse against any Stakeholder for satisfaction of any such indemnification obligations.

(e) No Special Damages. No Indemnifying Party will be liable to any Indemnitee for indirect, consequential, punitive or special damages (except as may be imposed on an Indemnitee in connection with a Third Party Claim).

Section 10.7 Environmental Remediation Standard. To the extent that a claim for indemnification under this Article X involves contamination or a requirement for remediation, investigation, or corrective action to address pollution, contamination, or a release of Hazardous Materials, the Indemnitee's recovery from an Indemnifying Party shall be limited to those expenses reasonably necessary to achieve the most cost-effective remediation standard permitted under applicable Environmental Laws, unless the lease for such asset or property requires contamination to be remediated to a more stringent standard, in which case that standard shall apply to the remediation.

Section 10.8 Payment of Indemnity. Upon final agreement by the parties or the entry of a final, non-appealable order by a court of competent jurisdiction that an Indemnitee is entitled to indemnification under this Article X, (a) Parent, if it is the Indemnifying Party, must promptly pay the Indemnitee for all Losses to which it is entitled to be indemnified hereunder and (b) the Reserve Agent, if the Stakeholders are the Indemnifying Party, must promptly release to the Indemnitee the number of Reserve Shares that it is entitled to receive hereunder from the Reserve Account, to the extent that Reserve Shares are available in the Reserve Account therefor.

Section 10.9 Effectiveness; Exclusive Remedy. This Article X shall become effective at the Effective Time and shall be of no force and effect prior to the Effective Time or at any time after this Agreement is terminated pursuant to Section 9.1. Following the Effective Time, the indemnification provisions set forth in this Article X will be the sole and exclusive remedy of the parties to this Agreement with respect to any and all claims relating to the subject matter of this Agreement or relating to Environmental Liabilities, Environmental Law or Hazardous Material (other than a claim for fraud or a claim for specific performance of the terms of this Agreement and other than with respect to Deferred Adjustment Claims).

Section 10.10 Risk Allocation. The representations, warranties, covenants and agreements made herein are intended among other things to allocate the risks inherent in the transactions contemplated hereby between the parties and, accordingly, a party shall be entitled to the remedies prescribed by this Agreement by reason of any breach of any such representation, warranty, covenant or agreement by another party, notwithstanding whether any employee, representative or agent of the party seeking to enforce a remedy knew or had reason to know of such breach. The right to indemnification, reimbursement, or other remedy based on such representations, warranties, covenants and obligations will not be affected by any investigation conducted with respect to, or any knowledge acquired (or capable of being acquired) about, the accuracy or inaccuracy of or compliance with, any such representation, warranty, covenant or obligations.
