ARTICLE XI

TAXES

11.01 Ad Valorem and Property Taxes. All ad valorem taxes, real property taxes, personal property taxes and similar obligations (“Property Taxes”) attributable to the Assets shall be apportioned as of the Effective Time between Sellers and Buyer; provided, however, that any such taxes which are calculated based on the value or amount of production during a given period shall be apportioned to the period during which such production occurred; regardless of the date on which such taxes are assessed and/or payable. The owner of record on the assessment date shall file or cause to be filed all required reports and returns incident to the Property Taxes and shall pay or cause to be paid to the taxing authorities all Property Taxes relating to the tax periods during which the Effective Time occurs. If Sellers is the owner of record on the assessment date, then Buyer shall pay to Sellers, Buyer’s pro rata portion, if any, of such Property Taxes within fifteen (15) days from the date such taxes are required to be

paid to the taxing authorities and after receipt of Sellers’ invoice therefor, except to the extent taken into account as an adjustment to the Initial Payment pursuant to Article 2.02. If Buyer is the owner of record as of the assessment date then Sellers shall pay to Buyer Sellers’ pro rata portion of such Property Taxes, if any, within fifteen (15) days from the date such taxes are required to be paid to the taxing authorities and after receipt of Buyer’s invoice therefore, except in the extent taken into account as an adjustment to the Purchase Price pursuant to Article 2.03.

11.02 Transfer Taxes. Buyer shall be liable for all Transfer Taxes (as defined below) required to be paid in connection with the sale of the Assets pursuant to this Agreement. If the transfer of the Assets pursuant to this Agreement is exempt from applicable Transfer Taxes, Buyer shall, at Closing, provide Sellers with proof thereof. As used herein, the term “Transfer Taxes” means any sales, use and excise taxes.

11.03 Other Taxes. All taxes (other than franchise and income taxes and taxes covered by Articles 11.01 and 11.02) attributable to the Assets that are imposed on or with respect to the production of oil, natural gas or other hydrocarbons or minerals or the receipt of proceeds therefrom (including but not limited to severance, production, and excise taxes) shall be apportioned between the parties based upon the respective Security Assignments of production taken by the parties. All such taxes that have accrued with respect to the period prior to the Closing Date have been or will be properly paid by or on behalf of Sellers (although such taxes for the period between the Effective Time and the Closing Date will be taken into account as an adjustment to the Purchase Price pursuant to Article 2.02), and Sellers shall be responsible for filing or causing to be filed all statements, returns, and documents incident thereto. Buyer shall be responsible for paying or withholding or causing to be paid or withheld all such taxes which have accrued after the Closing Date and for filing all statements, returns, and documents incident thereto.

11.04 Cooperation. Each party to this Agreement shall provide the other party with reasonable access to all relevant documents, data and other information (other than that which is subject to an attorney-client privilege) which may be required by the other party for the purpose of preparing tax returns, filing refund claims and responding to any audit by any taxing jurisdiction. Each party to this Agreement shall cooperate with all reasonable requests of the other party made in connection with contesting the imposition of taxes. Notwithstanding anything to the contrary in this Agreement, neither party to this Agreement shall be required at any time to disclose to the other party any tax return or other confidential tax information. Except where disclosure is required by applicable law or judicial order, any information obtained by a party pursuant to this Agreement shall be kept confidential by such Party, except to the extent disclosure is required in connection with the filing of any tax returns or claims for refund or in connection with the conduct of an audit, or other proceedings in response to an audit, by a taxing jurisdiction.

11.05 Tax Indemnification. The following tax indemnification provisions shall apply to this Agreement

(a) Subject to the provisions of Article 11.05(b), Sellers shall indemnify Buyer from all liabilities for foreign, federal, state, local and Indian Tribal taxes in respect of the ownership or operation of the Assets prior to the Effective Time, together with penalties and interest thereon (provided such penalties and interest do not result from the negligence, late filing, fraud or acts of misfeasance or malfeasance of Buyer). Sellers shall be entitled to all refunds or rebates of taxes paid in respect of the ownership or operation of the Assets prior to the Effective Time. Subject to the provisions of Article 11.05(b), Buyer shall indemnify Sellers from all liabilities which are assessed for foreign, federal, state, local and other taxes, together with penalties and interest

thereon (provided such penalties and interest do not result from the negligence, late filing, fraud or acts of misfeasance or malfeasance of Sellers), to the extent such liabilities relate to the ownership or operation of the Assets from and after the Effective Time; provided, however, that such indemnity shall not apply to (i) income taxes arising out of the ownership of the Assets between the Effective Time and the Closing Date, (ii) Property Taxes apportioned to Sellers pursuant to Article 11.01, and (iii) other taxes imposed on or after the Effective Time, in each case to the extent (but only to the extent) such taxes are included in the determination of the Adjusted Initial Payment. Buyer shall be entitled to all refunds or rebates in respect of the ownership or operation of the Assets on or after the Effective Time, except refunds or rebates of (x) income taxes attributable to the ownership of the Assets between the Effective Time and the Closing Date, (y) Property Taxes apportioned to Sellers pursuant to Article 11.01, and (z) other taxes imposed on or after the Effective Time, in each case to the extent (but only to the extent) such refunds or rebates are a return of taxes included in the determination of the Adjusted Initial Payment.

(b) In order for Sellers or Buyer (“Claimant”) to make a claim against the other (“Indemnitor”) under this Article XI, Claimant shall give prompt notice to Indemnitor of any liability for which Claimant would claim indemnification under this Article XI, which notice shall include the circumstances surrounding such liability. Indemnitor shall then have the right but not the obligation, to contest such liability at its sole cost and expense by giving written notice to Claimant of such election within thirty (30) days after Indemnitor receives Claimant’s notice. Should Indemnitor fail to notify Claimant within such thirty (30) day period, Indemnitor shall be deemed to have elected not to contest such liability. Should Indemnitor elect (or be deemed to have elected) not to contest such liability, Indemnitor shall pay the full amount due under Article 11.05(a) in respect of such liability to Claimant in cash within thirty (30) days after Indemnitor elects (or is deemed to have elected) not to contest such liability. Except as specifically provided in this Article 11.05 with respect to certain tax issues which must be combined or joined with other tax issues, if Indemnitor elects to contest any such liability, Claimant shall give Indemnitor full authority to defend, adjust, compromise or settle such liability and any action, suit, or proceeding in which Indemnitor contests such liability, in the name of Claimant or otherwise as Indemnitor shall elect. In any administrative or legal proceeding, Indemnitor shall employ counsel selected by it and reasonably acceptable to Claimant. With respect to tax issues incident to any such liability that must be combined or joined with one or more other tax issues which Claimant desires to contest, Claimant and Indemnitor shall cooperate fully, and control of any administrative legal proceeding shall rest with the party having the greater ultimate liability (including liability under Article 11.05(a) for the taxes in dispute). The party in control may not adjust, compromise or settle taxes which are contested by or on behalf of the other party without the consent of the other party. With respect to any liability contested by Indemnitor under the terms of this Article 11.05(b), Indemnitor shall pay the full amount due under Article 11.05(a) in respect of such liability to Claimant in cash within thirty (30) days after the liability is finally determined either by settlement or pursuant to the final unappealable judgment of a court of competent jurisdiction.

12.01 Governing Law. THIS AGREEMENT SHALL BE ENFORCED, GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS

APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED ENTIRELY WITHIN SUCH STATE, WITHOUT REGARD TO THE PRINCIPLES OF CONFLICT OF LAWS.

12.02 Dispute Resolution. The parties to this Agreement acknowledge that disputes may arise between them, and it is in their best interests to resolve such disputes in an orderly and consistent manner, and agree as follows:

(a) The parties will attempt to resolve promptly any controversy or claim arising out of or relating to this Agreement or the transactions contemplated or consummated pursuant to this Agreement (a “Dispute”), by negotiating directly and in good faith. Both parties may seek the advice and assistance of legal counsel in connection with any such negotiation.

(b) If the parties cannot resolve and settle a Dispute by private negotiation within sixty (60) days after one party gives the other written notice that a Dispute exists, the parties mutually agree to submit the Dispute to non-binding mediation, as follows:

(i) Mediation shall occur in Dallas, Texas, before a single mediator, using the facilities and mediation rules of a professional dispute-resolution organization selected by mutual agreement of the parties (the “Mediation Organization”). If the parties cannot agree on a Mediation Organization, they will use the facilities and mediation rules of Judicial Arbitration and Mediation Services, Inc. in Dallas, Texas (“JAMS”).

(ii) The parties shall jointly select a mediator from the panel of mediators maintained by the Mediation Organization. The mediator must be an attorney who has no prior business or professional relationship with either party. If the parties are unable to agree on a mediator within thirty (30) days after the Dispute is submitted to mediation, the Mediation Organization will select a mediator who possesses the indicated qualifications.

(iii) The parties will share the filing fee for the mediation equally, but will otherwise separately bear their own costs and expenses (including legal fees) of participating in the mediation process. Each party agrees to send at least one representative to the mediation conference who has authority to enter into binding contracts on that party s behalf. Each party further agrees to sign a confidentiality agreement that prohibits the mediator from disclosing, orally or in writing, any information the other party discloses to the mediator in confidence at any stage of the mediation process.

(iv) Either party’s failure or refusal to participate in mediation in accordance with this Subsection 12.02(b) shall be considered a dispute subject to binding arbitration in accordance with Subsection 12.02(c).

(i) Either party may make a demand for arbitration.

(ii) Arbitration proceedings shall be conducted in Dallas, Texas, before a single arbitrator, using the facilities and commercial arbitration rules of the Mediation Organization or another professional dispute-resolution organization selected by Buyer and reasonably acceptable to Sellers (the “Arbitration Organization”). If Buyer selects an

Arbitration Organization other than the Mediation Organization and Sellers reasonably object to Buyer’s choice, the parties will use JAMS’ facilities and commercial arbitration rules.

(iii) The Arbitration Organization’s expedited arbitration procedure shall apply to the arbitration proceedings. The parties do waive the application of all rules of discovery and evidence under the laws of the State of Texas.

(iv) The parties shall jointly select an arbitrator from the panel of arbitrators maintained by the Arbitration Organization. The arbitrator must be an attorney who has no prior business or professional relationship with either party and who agrees to follow and apply the express provisions of this Agreement in determining his or her award. If the parties are unable to agree on an arbitrator within thirty (30) days after the arbitration demand is filed, the Arbitration Organization will select an arbitrator who possesses the indicated qualifications.

(v) The arbitrator’s award shall be final and binding on all parties, and neither party shall have any right to contest or appeal the arbitrator’s award except on the grounds expressly provided by the United States Arbitration Act (the “Arbitration Act”). The party who demands arbitration shall pay the arbitration filing fee, but the parties will otherwise separately bear their own costs and expenses (including legal fees) of participating in the arbitration process. Responsibility for the arbitrator s fees and expenses shall be determined as part of the arbitrator’s award.

(vi) The procedures contemplated by and the enforceability of this Subsection 12.02(c) shall be governed by the Arbitration Act and shall be interpreted and enforced in accordance with United States federal judicial interpretations of the Arbitration Act.

(d) The parties further agree to submit to the jurisdiction and venue of JAMS and that service of process by certified mail, return receipt requested, shall be sufficient to confer in personam jurisdiction over them. Buyer specifically agrees to waive all questions of personal jurisdiction or venue (excepting only lack of proper service) for the purpose of carrying out this provision.

(e) The party which does not prevail in any Dispute submitted to binding arbitration as required by this Agreement shall be responsible for all fees and expenses, including attorneys’ fees, incurred by the prevailing party in connection with such Dispute.

PURCHASE AND SALE AGREEMENT

Deposit Escrow Agreement

ESCROW AGREEMENT

THIS ESCROW AGREEMENT (this “Agreement”) is made and entered into this 25th day of June, 2010, by and among Hop-Mar Energy, L.P., a Texas limited partnership (“Hop-Mar”), Sydri Energy Investments I, Ltd., a Texas limited Partnership (“Sydri”), Snyder Energy Investments, Ltd., a Texas limited partnership (“Snyder”), and Woodbine Energy Partners, L.P. a Texas limited partnership (“Woodbine,” and collectively with Hop-Mar, Sydri and Snyder, “Sellers”), Southern Bay Energy, LLC, a Texas limited liability company (“Buyer”), and Xxxxx Xxxxx & Xxxxxxx, a Texas professional corporation (the “Escrow Agent”). Except as otherwise expressly defined herein, each term used herein with its initial letter capitalized that has been defined in the Purchase and Sale Agreement (as defined below) shall have the same meaning herein as ascribed to it in said Purchase and Sale Agreement.

Background

Sellers and Buyer are parties to a Purchase and Sale Agreement of even date herewith (the “Purchase and Sale Agreement”), pursuant to which they have agreed to deposit five percent (5%) Purchase Price in escrow with the Escrow Agent to be held, administered and distributed on the terms and conditions hereinafter set forth.

Terms and Conditions

For and in consideration of the mutual covenants and agreements herein set forth and other good and valuable consideration, the receipt and sufficiency of which hereby are acknowledged, the parties hereto agree as follows:

1. Escrow Deposit. Sellers and Buyer hereby deposit with the Escrow Agent, and the Escrow Agent hereby acknowledges receipt of, funds in the aggregate amount of Eight Hundred Thirty Thousand Dollars ($830,000) (the “Escrow Funds”), which shall be held and dealt with by the Escrow Agent in accordance with the terms and conditions of this Agreement.

2. Investment of the Escrow Funds. The Escrow Funds shall be invested by the Escrow Agent in a money market or similar account that is interest-bearing and allows periodic withdraws. The Escrow Agent is hereby authorized and directed by Sellers and Buyer to liquidate from time to time any investment or investments in order to make any distributions required by this Agreement, notwithstanding any economic consequences of liquidating such investment prior to its maturity.

3. Release of Escrow Funds. The Escrow Agent shall distribute the Escrowed Funds, along with any accrued interest, to Sellers in proportion to their respective percentage interests in the Assets at the Closing; provided, however, that if the Closing does not occur as provided in the Purchase and Sale Agreement, by reason of the proper exercise by Buyer or Seller, as the case may be, of its or their right to

terminate the Purchase and Sale Agreement by reason of Article 3.06 thereof, the Escrow Agent shall return the Escrow Fund, along with any accrued interest, to Buyer as soon as reasonably practical following delivery by Buyer or Sellers to the Escrow Agent of written notice of such exercise of rights under said Article 3.06.

4. Rights of Escrow Agent. In addition to its other rights contained elsewhere in this Agreement, the Escrow Agent shall have the following rights under this Agreement:

(a) The Escrow Agent undertakes to perform only such duties as are expressly set forth herein, and shall not be required to take any other action with respect to any other matter which might arise in connection with this Agreement or the Escrow Fund in carrying out its duties hereunder. The Escrow Agent is not responsible in any manner for the sufficiency, correctness, genuineness or validity of any of the documents, certificates, instruments or notices deposited with the Escrow Agent pursuant to this Agreement or for the form or execution thereof, or for the identity or authority of any person executing or depositing the same.

(b) The Escrow Agent may rely, and shall be protected in acting or refraining from acting, upon any written notice, instruction, certificates or request furnished to it hereunder and believed by it to be genuine and to have been signed or presented by the proper party or parties; provided, however, that, as set forth below, any modification to this Agreement shall be signed by all of the parties hereto. Sellers and Buyer shall indemnify the Escrow Agent, as well as its agents and representatives, against and in respect of any and all direct or indirect damages, claims, losses, liabilities and expenses (including without limitation, attorneys’ fees) incurred by the Escrow Agent which may arise out of or result from any false or incorrect notice, certificate or other communication delivered pursuant to this Agreement by such party.

(c) In the event of any disagreement or controversy arising under this Agreement or if conflicting demands or notices are made upon the Escrow Agent growing out of or relating to this Agreement or in the event the Escrow Agent in good faith is in doubt as to what action it should take hereunder, the Escrow Agent shall have the right, at its election, to (i) withhold and cease all further proceedings under, and performance of, this Agreement, and of all instructions received hereunder, and resign as Escrow Agent effective upon the appointment of a successor Escrow Agent by Sellers and Buyer (as contemplated by Section 4(e) below), or (ii) file a suit in interpleader and obtain an order from a court of competent jurisdiction requiring all parties involved to interplead and litigate in such court their claims and rights among themselves and with the Escrow Agent. The foregoing remedies shall be in addition to any other remedies available to the Escrow Agent provided by law. Should any suit or legal proceeding be instituted growing out of or related to this Agreement, whether such suit be initiated by the Escrow Agent or others, the Escrow Agent shall have the right, at its option, to cease all further proceedings under, and performance of, this Agreement, and of all instructions received hereunder until all differences and doubts have been resolved by agreement or until the rights of all parties shall have been fully and finally adjudicated.

(d) Sellers and Buyer hereby jointly and severally agree to indemnify the Escrow Agent for, and to hold it harmless against, any loss, liability or expense (including, without limitation, attorneys’ fees) incurred by it without negligence or bad faith on its part arising out of or in connection with its entering into this Agreement and the carrying out of its duties hereunder, including the costs and expenses of defending itself against any claim of liability hereunder or in connection therewith. The Escrow Agent may consult with counsel of its own choice as to any matters arising hereunder, and shall have full and complete authorization and protection for any

action taken or suffered by it hereunder in good faith and in accordance with the opinion of such counsel.

(e) The Escrow Agent may resign and be discharged from its duties or obligations hereunder by giving notice of such resignation to Sellers and Buyer, specifying the date upon which such resignation shall take effect, which shall be at least thirty (30) days after the date of such notice. Sellers and Buyer, acting joint, shall have the right to terminate the appointment of the Escrow Agent hereunder by giving to it notice of such termination specifying the date upon which such termination shall take effect, which shall be at least thirty (30) days after the date of such notice. In either such event, Sellers and Buyer hereby agree to mutually designate a successor Escrow Agent, and the parties hereto agree that, upon demand of such successor Escrow Agent, all property in the Escrow Fund shall be turned over and delivered to such successor Escrow Agent, which shall, thereupon, be bound by all of the provisions hereof.
