3.02 Additional Considerations. As additional consideration to this Agreement:

(a) XTO Energy reserves the Overriding Royalty Interest as defined and further described in Article 4 herein; and

(b) Buyer agrees to provide the information described on the attached Exhibit H for any New Xxxxx (as defined in Article 4).

3.03 Performance Deposit and Payment. As evidence of good faith, Buyer has deposited with XTO Energy a performance deposit of $18,250,000.00 (the “Performance Deposit”). The Performance Deposit will be credited to the Base Purchase Price at Closing, will not bear interest, and is not refundable except as provided in this Agreement. If Closing does not occur as to any Interest, and this Agreement provides that the Performance Deposit allocable on a pro rata basis to that Interest is to be refunded for any reason, XTO Energy will deduct any amounts due to it under this Agreement and remit the remainder of the Performance Deposit to Buyer, without interest.

XTO Energy, solely at its discretion, may rely on these allocations and reserves the right to review the Allocation.

ARTICLE IV
RESERVED OVERRIDING ROYALTY

4.01 Reserved Overriding Royalty. XTO Energy shall reserve from the leasehold interest applicable to each of the oil and gas leases described on Exhibit A (collectively, the “Leases”, individually a “Lease”), an overriding royalty interest equal to five percent of eight-eighths (5% of 8/8ths) as to production from any New Xxxxx, as defined hereafter (“Overriding Royalty Interest”). “New Xxxxx”, for the purposes of this Article 4, is defined as any xxxxx drilled on the Leases from and after the Closing Date, together with any sidetrack or deepening after the Closing Date of an existing well on the Leases, to the extent and only to the extent that said sidetrack bottom hole is located 1,000 feet or greater from the bottom hole location of such existing well; provided, however, such 1,000 foot restriction does not apply to the sidetracks identified in that certain Letter between XTO Energy and Buyer, dated July 29, 2011. New Xxxxx shall not include any recompletions, workovers, or mechanical bypasses of an existing well. The Overriding Royalty Interest shall be paid and/or delivered by Buyer to XTO Energy in accordance with the following terms and conditions:

(a) On oil, delivery of such oil shall be made free of all costs and expenses in developing and operating the Interests, free of all costs of production and unencumbered in any way to XTO Energy’s credit into the pipelines or tanks to which the applicable well or xxxxx may be connected, or otherwise as XTO Energy may from time to time direct. Should XTO Energy elect not to take its overriding royalty on oil in kind, then XTO Energy’s part of such oil shall be paid based upon the same market value as received by Buyer with respect to its Interests pursuant to an arm’s length contract with a third party purchaser of such oil at the applicable well or xxxxx, free of all costs and expenses in of developing and operating the Interests, free of all costs of production and unencumbered in any way.

(b) On all gas, including casinghead gas or other gaseous substances and liquid constituents of said gas, produced from and sold (on or off the Interests) or used off the Interests, or for the extraction of gasoline or other products therefrom, the overriding royalty shall be based upon the same market value as received by Buyer with

respect to its Interests pursuant to an arm’s length contract with a third party purchaser at the well or xxxxx of gas so produced, sold or utilized, free of all costs of developing and operating the Interests, free of all costs of production.

Payment by Buyer of the Overriding Royalty Interest must be made from the Closing Date and at all times thereafter on the basis of one hundred percent (100%) of the New Well’s production (proportionately reduced as hereafter provided), and such payment must be made regardless of (a) whether Buyer is or is not banking or storing gas, whether pursuant to the provisions of an agreement so permitting, or otherwise; (b) whether Buyer is or is not selling all or any part of its share of the total production; and (c) the identity of the purchaser or purchasers of such gas if Buyer should be selling all or any part of the total gas produced. The Overriding Royalty Interest shall be delivered to XTO Energy free of all cost and expense of developing and operating the Leases and free and clear of all taxes except gross production, severance taxes, and ad valorem taxes applicable thereto; provided that, the Overriding Royalty Interest will be subject to and bear a proportionate share of all reasonable costs and expenses of a non-affiliated third party incurred for the transportation, compression, dehydration and treating of the said gas and condensate in the preparation for marketing of such production. Such payments shall be made on or before the sixtieth (60th) day following the month of the production. If payment is not made within the time prescribed, the unpaid amount will bear interest at the rate of one percent (1%) for each month or fraction of a month, by which payment is delayed, or the maximum lawful rate, whichever is less. Buyer agrees to send all division orders covering the Overriding Royalty Interest retained to XTO Energy at the address shown in Article 23 of the Purchase and Sale Agreement.

If the Leases cover less than a full interest in the land covered thereby or if the interest assigned hereunder in said Leases is less than a full interest, then the Overriding Royalty Interest herein reserved shall be reduced in the proportion that the interest assigned to Buyer herein bears to the full interest in the land covered or bears to the full interest in the Leases assigned hereunder; provided, however, that the overriding royalties herein reserved are exclusive of and in addition to any royalties, overriding royalties or payments out of production affecting the Leases as of the Effective Time. It is expressly agreed that operations, if any, on the Leases and the extension and duration thereof, as well as the preservation of the Leases by rental payments or otherwise, shall be solely at the will and discretion of Buyer or any successor owner of the working interest in the Leases. The Overriding Royalty Interest hereby reserved is subject to the rights conferred on the lessees (now Buyer) by said Leases to pool or unitize the lands covered thereby; and neither the joinder nor consent by XTO Energy shall be required in connection with any such pooling or unitization. Where oil and/or gas is produced from any unit so formed, XTO Energy shall receive on production from such unit only such portion of the overriding royalty stipulated herein, as the amount of surface acreage of the land affected by such overriding royalty and placed in said unit bears to the total surface acreage included in the unit, unless some other formula for appointment of production is adopted for the unit and in such case the formula shall be used.

XTO Energy upon notice in writing to Buyer, shall have the right to audit Buyer’s accounts and records relating to the Overriding Royalty Interest reserved herein and any other records related to the determination of the amounts due XTO Energy for any calendar year within the twenty-four (24) month period following the end of such calendar year.

The Overriding Royalty Interest is expressly subject to the terms and provisions of any of the Related Agreements, to the extent and only to the extent that such terms and provisions contractually apply to and prohibit the establishment of an overriding royalty interest affecting any of the Leases. If pursuant to the terms of any Related Agreement all or a portion of Buyer’s interest in a Lease, or all or a portion of its interest in the production therefrom, is forfeited or assigned to one or more other working interest owners, either permanently or for a stipulated period, because Buyer fails to participate in any operation or operations, then to the extent that such forfeited or assigned interest is subject to and burdened by the Overriding Royalty Interest, the working interest so assigned or forfeited by Buyer shall be free and clear of such Overriding Royalty Interest for the period of such forfeiture or assignment of overriding royalty interests. The Overriding Royalty Interest will become effective again when the interest is reassigned or reverts back to Buyer, and Buyer shall pay such Overriding Royalty Interest as provided in this Section 4.01. Further, to the extent any Related Agreement establishes security rights in favor of the parties thereto; the Overriding Royalty Interest conveyed herein shall be subordinated to such security rights.

It is understood and agreed that the Overriding Royalty Interests reserved herein, will be a permanent burden on the Leases subject to the provisions of this Section 4.01, and will continue in effect as to each Lease for so long as each Lease remains in effect. In addition in the event Buyer secures a renewal or extension for any such Leases, covering all or any part of the land previously covered thereby, then the interests reserved herein will apply to such renewed or extended Lease. A “renewal” or “extension” of a Lease as those terms are used therein shall mean any Lease or Leases covering all or a part of the land covered by the Leases that is executed by Buyer within twelve (12) months after termination of any Lease, or the next ensuing Federal or state lease sale pertaining to all or any part of the land previously covered by a Lease, whichever may come first.

Notwithstanding anything to the contrary set forth in this Agreement, the Overriding Royalty Interest shall not apply to any production attributable to Block 188, Ship Shoal Area, OCS Leasing Map, Louisiana Map No. 5, INSOFAR AND ONLY INSOFAR AS to those depths from 17,000 feet subsea down to 100,000 feet subsea, currently affected by that certain federal offshore lease bearing serial number OCS-G 22712, dated May 1, 2001, granted by the United States of America, as Lessor, in favor of Aviara Energy Corporation, as Lessee, that being the same interest referenced in Section 1.19(n).

Furthermore, unless otherwise agreed by XTO Energy, the accounting firm shall not disclose information to Buyer that is proprietary to XTO Energy or its Associated Parties, including gas and liquids sales prices.

5.03 Environmental Assessment. Buyer and its Associated Parties may inspect the premises and conduct an environmental assessment of the Interests and Property, including investigations to identify wetlands and sensitive and protected habitats, but Buyer must execute the form of environmental testing and confidentiality agreement attached as Exhibit F before performing an assessment. if Buyer undertakes an environmental assessment, both the Buyer’s

consultant (if consultants are employed) and the scope of the proposed assessment, including testing protocols, must be approved in writing by XTO Energy before the work may begin. If Buyer and XTO Energy cannot agree on Buyer’s proposed environmental assessment plan, then XTO Energy may, at its sole option, withdraw from this Agreement any of the Interests that Buyer proposes to assess or all the Interests, and the Base Purchase Price will be adjusted by the Allocation for each withdrawn Interest. If XTO Energy withdraws all the Interests, this Agreement will terminate, and XTO Energy will refund the Performance Deposit to Buyer.

If Buyer takes samples from the Property, XTO Energy may require splitting of each sample. Buyer will deliver copies of all draft and final reports, results, data, and analyses of the site visits, inspections, and assessments to XTO Energy within five (5) days of Buyer’s receipt of them, at Buyer’s cost. XTO Energy will have no confidentiality obligation with regard to this information and may disclose it to third parties or use it for any purpose.

5.04 Access to Interests Operated by Others. On request, XTO Energy will assist Buyer by making initial contact with the Operators of the Interests that are operated by others, but Buyer will be responsible for contacting each Operator to arrange for review of the Interests.

ARTICLE VI
TITLE AND TITLE DEFECTS

6.01 Title Defect. “Title Defect” means any one of the following:

(a) XTO Energy’s title at the Effective Time as to all or any part of the Interests is subject to an outstanding mortgage, deed of trust, lien, or other monetary encumbrance or adverse claim not listed or referenced on Exhibit A and Exhibit A-1 that would induce a purchaser to suspend payment of proceeds for the Interest or require the furnishing of security or indemnity. Evidence that XTO Energy receives its full share of proceeds from a purchaser or third-party Operator attributable to an Interest creates a rebuttable presumption that no Title Defect exists with respect to the Interest;

(b) XTO Energy’s net revenue interest for an Interest at the Effective Time is less than that shown on Exhibit A-2, or XTO Energy’s working interest for an Interest at the Effective Time is greater than shown on Exhibit A-2 without a corresponding increase in the net revenue interest for such Interest;

(c) XTO Energy’s interest would be reduced if a third party were to exercise a reversionary, back-in, or other similar right not listed or referenced on Exhibit A-2; or

(d) XTO Energy is in material default under some material provision of a lease, farmout agreement, or other agreement, resulting in loss of all or any part of the Interests.

“Title Defect” does not include (a) a lien or encumbrance in the form of a judgment secured by a supersedeas bond or other security approved by the court issuing the order; or (b) the loss of lease acreage between the Effective Time or the Execution Date (whichever is earlier) and the Closing Date, because the lease term expires.

Buyer must notify XTO Energy in writing promptly if Buyer determines that XTO Energy’s net revenue interest or working interest for an Interest is greater than that shown on Exhibit A-2.

6.02 Adjustments to Allocations.

(a) Buyer may request an adjustment to an Allocation at any time on or before the 5th day before the Closing Date, if the adjustment is based on a Title Defect. XTO Energy may request an adjustment to the Base Purchase Price based on an Allocation at any time before the Closing Date, if XTO Energy’s net revenue interest for the Interest is

greater than that shown on Exhibit A-2. A notice requesting an adjustment must be timely and in writing and include appropriate documentation to substantiate the adjustment, or the claimant will be deemed to have waived its claim to adjust the Base Purchase Price based on an Allocation for the matter stated in the notice.

(b) If either Party gives notice under the previous Section, the Parties will meet and use their best efforts to agree on the validity of the claim and, if applicable, the amount of the adjustment, using the following criteria:

(i) If the claim is based on XTO Energy’s owning a different net revenue interest than that shown on Exhibit A-2, then the adjustment will be the absolute value of the number determined by the following formula:

Adjustment = A x (1-[B/C])

A = Allocation for the affected Interest

B = correct net revenue interest for the affected Interest

C = net revenue interest for the affected Interest as shown on Exhibit A-2.

(ii) If the claim is based on an obligation or burden that is liquidated in amount, then the adjustment will be the sum necessary to remove the obligation or burden from the affected Interest.

(iii) If the claim is based on an obligation or burden that is not liquidated, but can be estimated with reasonable certainty, the adjustment will be the sum necessary to compensate Buyer on the Closing Date for the adverse economic effect on the affected Interest.

(c) If the amount of the adjustment for each Title Defect cannot be determined based on the above criteria, and if the Parties cannot otherwise agree on the amount of an adjustment by the Closing Date, XTO Energy may, at its sole option and upon written notice to Buyer, either:

(i) terminate this Agreement and refund the Performance Deposit;

(ii) remove the affected Interest from this Agreement and adjust the Base Purchase Price by the Allocation for that Interest;

(iii) elect to cure the Title Defect pursuant to Section 6.02(e); or

(iv) elect to resolve the dispute pursuant to the provisions of Article 17.

(d) The Base Purchase Price will be adjusted only if the sum (i.e. offsetting of increases and decreases) of all adjustments under this Section 6.02 is greater than $250,000.00. If the sum of all adjustments would result in the Base Purchase Price being

reduced by more than ten percent (10%), XTO Energy may, upon written notice to Buyer, either:

(i) terminate this Agreement and refund the Performance Deposit; or

(ii) remove the affected Interest from the Agreement and adjust the Base Purchase Price by the Allocation for that Interest.

(e) XTO Energy may, at its sole option, notify Buyer before the Closing Date that it elects to cure some or all of the Title Defects. No adjustment will be made at Closing for the Title Defects that XTO Energy elects to cure. If any Title Defect is not cured within ninety (90) days after Closing, an adjustment to the Base Purchase Price will be calculated and made under the criteria set forth in this Section 6.02, and subject to the limitations contained in Section 6.02(d).

6.03 Description and Other Errors.

(a) If either Party determines, either before or within one (1) year after Closing that:

(i) certain Interests were erroneously included in or excluded from the Agreement or the conveyancing instruments; or

(ii) certain gas-production imbalance accounts were erroneously included in or erroneously excluded from this Agreement,

then XTO Energy and Buyer will meet and use their reasonable efforts to resolve the error. If necessary, the Parties will execute and record (if after Closing) appropriate correction instruments to correct the error.

(b) If XTO Energy and Buyer cannot resolve an error with respect to such an error discovered before the Closing Date, then XTO Energy may, at its sole option, either:

(i) with Buyer’s consent, terminate this Agreement and refund the Performance Deposit;

(ii) remove the affected Interest from this Agreement, if applicable, and adjust the Base Purchase Price by the Allocation for such Interest; or

(iii) elect to resolve the dispute pursuant to the provisions of Article 17.

(c) If XTO Energy and Buyer cannot resolve such an error with respect to an Interest assigned to Buyer and discovered within one (1) year after the Closing Date, then Buyer, upon written demand by XTO Energy at its sole option, will reassign all or any part of the Interests assigned to Buyer under this Agreement in the same manner as provided in Section 9.05, and undertake all other acts reasonably required to return XTO Energy to its pre-Closing position as to the reassigned Interest, including revising

regulatory filings. XTO Energy will refund to Buyer the Allocation for each reassigned Interest, without interest, upon Buyer’s performance of its obligations under this Section 6.03(c).

Notwithstanding the foregoing, the Parties will cooperate at all times after Closing to execute and record correction instruments to correct scrivener’s errors in the preparation of Closing documents.

6.04 Restrictions on Use. Where any of the Interests include a fee simple interest in real property that has been used for oil, gas, or other mineral operations, including pipeline operations, the Buyer covenants that it will not use or develop the real property for the following uses, in whole or in part, and the Buyer acknowledges such uses are expressly prohibited and forbidden:

Buyer acknowledges that depending upon the nature of the Buyer’s development that engineering controls that may need to be considered for use by the Buyer include: vapor barriers; vapor installation systems; scaled sumps and storm pond liners. Necessity of engineer controls shall be determined by a professional engineer licensed in the state with experience in the field.

6.06 Covenants Running with the Land. The covenants contained in provisions 6.04 and 6.05 of this Agreement shall be covenants running with the land, shall be recorded in the real property records, and shall be binding on Buyer and its successors and assigns.

ARTICLE VII
PRE-CLOSING OBLIGATIONS

7.01 Preferential Rights.

(a) Notice. Promptly upon execution of this Agreement, XTO Energy will notify the preferential rights holders, if any, of applicable preferential rights to purchase the Interests. Prior to sending such notifications, an advance copy of the notice will be provided to Buyer.

(b) Adjustment to Base Purchase Price. If a third party gives notice of its intent to exercise a preferential right to purchase any of the Interests, such Interest will be removed from this transaction, subject to (c) below, and the Base Purchase Price will be adjusted by the Allocation for the preferential right property. If Buyer has allocated a positive dollar amount to the preferential right property, the Base Purchase Price will be reduced by the dollar amount of the positive Allocation. If Buyer has allocated a negative dollar amount to the preferential right property, the Base Purchase Price will be increased by the absolute value of the negative Allocation.

(c) Third Party Failure to Purchase. If a third party gives notice of its intent to exercise a preferential right to purchase any of the Interests, but does not close the purchase for any reason either before or within a reasonable time after Closing, Buyer will be obligated to acquire the preferential right property under the terms of this Agreement, for the positive dollar Allocation (or if the Allocation is a negative amount, XTO Energy will refund the absolute value of the negative amount to Buyer, without interest). Closing on the preferential right property will be scheduled to occur within forty-five (45) days after Buyer receives XTO Energy’s notice that the third party has not closed. The effective time for the preferential right property will be the Effective Time under this Agreement.

(d) Waiver of Preferential Rights. If a third party holding a preferential right to purchase any of the Interests has not waived such right prior to the Closing and the period to exercise such preferential right has not yet expired by the scheduled Closing Date, Closing on such preferential right property will postponed for a maximum period of five (5) days after the preferential right period has expired without being exercised and the Base Purchase Price for the unaffected Interests will be adjusted by the Allocation for such preferential right property in connection with the Closing with respect to the unaffected Interests. The Closing Date with respect to the unaffected Interests shall not be delayed.

7.02 Related Agreements. Except as otherwise provided in this Agreement, the sale of the Interests will be subject to all oil, gas, and mineral leases, assignments, subleases, farmout agreements, unit agreements, joint operating agreements, pooling agreements, letter agreements, easements, rights-of-way, gathering and transportation agreements, sales agreements, and other agreements concerning or pertaining to the Interests (“Related Agreements”), to the extent that they are binding on XTO Energy or its successors or assigns. Buyer will assume all of XTO Energy’s obligations and liabilities under the Related Agreements as of the Effective Time,

insofar as the obligations or liabilities concern or pertain to the Interests, and the Parties will execute all documents necessary for Buyer to assume the Related Agreements. Buyer’s obligation applies to all Related Agreements, whether recorded or not. Based on XTO Energy’s information and belief, after reasonable inquiry to the appropriate personnel, all material Related Agreements pertaining to the Interests are identified on Exhibit A, Exhibit A-1, Exhibit B, and/or Exhibit B-1.

7.03 Third Party Notifications and Approvals. The sale of the Interests may require the approval or consent of lessors, joint interest owners, farmors, sublessors, assignors, grantors, parties to agreements, governmental bodies having jurisdiction, or other third parties. XTO Energy is responsible, at its sole cost, for obtaining approvals from all applicable third parties and will furnish Buyer with a list of required third-party consents, as well as proof of each consent, approval, or waiver obtained before the Closing Date, except with respect to approvals from governmental bodies that are customarily obtained post-Closing. As to all such governmental body approvals, evidence of receipt of same shall be provided by Buyer to XTO Energy promptly upon receipt thereof as provided in Section 9.04.

(a) delay Closing as to any or all of the Interests, with no charge to either Party for the delay;

(b) with Buyer’s consent, close without all third party approvals; or

(c) with Buyer’s consent, remove the affected Interest from this Agreement and adjust the Base Purchase Price by the Allocation for that Interest.

If XTO Energy elects to close without all third party approvals, XTO Energy may require Buyer to reassign the affected Interest to XTO Energy if the third party refuses to approve the assignment after Closing. The reassignment will be in the manner described in Section 9.05.

7.04 Change of Operator. Unless otherwise provided by applicable law, regulation, or Related Agreement, Buyer, at its sole cost, must apply for and obtain any and all regulatory approvals and permits and satisfy requirements of financial security to operate the Interests either that it will operate or for which it intends to stand for election as Operator, and deliver copies or other evidence of compliance to XTO Energy before Closing.

8.04 Closing Obligations.

(a) Certificates of Authority. XTO Energy may require Buyer to deliver, at least five (5) days before the Closing Date, certificates in form and substance satisfactory to XTO Energy, effective as of the Closing Date and executed by Buyer’s duly authorized officer, partner, or owner, as appropriate, to the effect that:

(ii) each individual executing the closing documents has the authority to act on behalf of Buyer.

(b) Change of Operatorship. For XTO Energy-operated Interests, and except to the extent waived by XTO Energy, Buyer will deliver to XTO Energy on or before the Closing Date evidence of the following:

(i) that Buyer has complied with the requirements of all laws and regulations relating to the transfer of operatorship, including those regarding the assumption of responsibility for the plugging and abandoning of each Well that is included in the applicable Interests or located on the Property;

(ii) that the appropriate bond, surety letter, letter of credit, or other financial security has been accepted by the relevant regulatory agency; and

XTO Energy will submit the Closing Settlement Statement to Buyer, together with all available records or data supporting the calculation of amounts presented, no later than three (3) business days prior to the Closing Date. The Closing Settlement Statement shall be based upon actual information available to XTO Energy at the time of preparation and upon XTO Energy’s good faith estimates and assumptions. Prior to the Closing, Buyer shall review the Closing Settlement Statement and provide written notice to XTO Energy of any comments or objections in order that the Closing Settlement Statement can be modified, if necessary, prior to the Closing. If Buyer and XTO Energy agree on any changes to the Closing Settlement Statement, then the Closing Settlement Statement shall be adjusted accordingly. If the Buyer and XTO Energy do not agree on proposed changes to the Closing Settlement Statement, then Buyer will have funds available for Closing based on the information provided for in the original Closing Settlement Statement. XTO Energy will use estimates in the Closing Settlement Statement to the extent that estimates are necessary and may correct the estimates in the Final Settlement Statement.

(d) Closing Documents. The Parties, as indicated, will execute the following instruments to close this transaction:

The Assignment and Xxxx of Sale will be effective as of the Effective Time, be without warranty of any kind (e.g., title, fitness, condition), and restate the indemnities, releases, and waivers contained in this Agreement. Exhibit A-2 to this Agreement states XTO Energy’s working and net revenue interests, to the best of XTO Energy’s

knowledge and belief. The Assignment and Xxxx of Sale will not, however, state or warrant the working or net revenue interests assigned to Buyer.

If XTO Energy will own an interest after Closing in any Interest or Property (excluding overriding royalties, but including deep rights, and facilities, equipment, or pipelines) or continue to own interests for which XTO Energy requires access across the Interests or Property in order to exercise its rights, then, in the Assignment and Xxxx of Sale, XTO Energy will reserve concurrent interests in the applicable easements, rights-of-way, contracts, and other rights relating to the retained or reserved interests. In the event XTO Energy retains an overriding royalty interest or other interest in production in the Interests, the Assignment and Xxxx of Sale shall also grant XTO Energy the right to audit Buyer’s records relating to such retained interest and to transport, utilizing applicable easements, rights-of-way and pipelines comprising a portion of the Interests and paying its proportionate share of any applicable third party transportation fees, any production attributable to the Overriding Royalty Interest that XTO Energy chooses to take-in-kind.

(ix) The performance bond, pursuant to the terms set forth in Section 8.04(f).

(e) Third-Party Consents. At Closing, XTO Energy will deliver proof of required third-party consents and approvals obtained unless XTO Energy, with Buyer’s consent, exercises its option to close without receipt of all third party consents and approvals, as provided in Section 7.03, in which case XTO Energy shall deliver to Buyer a notice reflecting which consents and/or approvals remain outstanding.

(f) Financial Security. As a condition of Closing, pursuant to Section 8.04(d)(9), Buyer shall deliver to XTO Energy a performance bond, in a form substantially similar to the form attached as Exhibit K, to guarantee Buyer’s obligations under this Agreement, including its obligations to abandon, restore and remediate the Interests and Properties, providing for a penal sum in the amount of thirty-five million dollars ($35,000,000.00) issued by RLI Insurance Company, or by a mutually acceptable financial institution, as surety, and providing for terms acceptable to such surety, XTO Energy and Buyer.

(i) Within thirty (30) days prior to the following dates, January 1, 2015 (“1st Redetermination Period”), January 1, 2018 (“2nd Redetermination Period”) and January 1, 2021 (“3`d Redetermination Period”), and every three (3) years thereafter (each a “Redetermination Period”), the Parties shall arrange for a mutually acceptable third party to determine the estimated costs of the total remaining obligations assumed by Buyer under Section 9.08 with respect to the Interests and Properties owned by Buyer. Within ninety (90) days following each such redetermination of the estimated costs, Buyer is required to have a fully executed bond in place issued by RL1 Insurance Company, or by a mutually acceptable financial institution, as Surety, and providing terms substantially similar to the form attached as Exhibit K, except that said bond shall provide for a penal sum that is equal to at least: sixty percent (60%) as regards the 1st Redetermination Period, seventy percent (70%) as regards the 2nd Redetermination Period and eighty percent (80%) as regards to the 3rd Redetermination Period and every Redetermination Period thereafter, of the estimated costs of the total remaining obligations of Buyer with respect to the Interests and Properties owned by Buyer as so redetermined. If a new bond is not issued at such Redetermination Period, Buyer will confirm in writing to XTO Energy that the current performance bond is for a penal amount equal to or greater than the above requirements; it being understood that the financial security described in this section is not intended to cover new xxxxx, pipelines and/or platforms or equipment installed on the Properties after the Effective Time.

Notwithstanding the provisions set forth above, if during any Redetermination Period it is determined that the estimated costs of the total remaining liabilities of Buyer is less than $3,000,000.00, then Buyer shall no longer be obligated to maintain the performance bond and the Parties shall execute such documentation as may be required to secure the release and termination of the performance bond.

(ii) Upon occurrence of any of the following, XTO Energy may draw on the performance bond, in whole or in part, without prior notice to Buyer:

(A) XTO Energy is required in any manner to perform obligations under Section 9.08, pursuant to an order or directive issued by a governmental body or regulatory agency; or

(B) the insolvency of Buyer; or

(C) Buyer passes a resolution, commences proceedings or has proceedings commenced against it (which proceedings are not stayed within twenty-one (21) days of service thereof on Buyer) in the nature of bankruptcy or reorganization resulting from insolvency or its liquidation or for the appointment of a receiver, administrator, trustee in bankruptcy or liquidator or its undertakings or assets; or

(D) With respect to any draw that occurs under this Section, XTO Energy will provide Buyer with a courtesy copy of the notice within twenty-four (24) hours of the performance bond draw request.

(iii) In the event that XTO Energy draws on any performance bond pursuant to its rights to do so under any of Section 8.04(f)(2)(B) —(C), then to guarantee Buyer’s P&A Obligations (as defined below) XTO Energy shall be entitled to devote the entirety of the funds from such draw down to obtaining solely for its own benefit its replacement financial security, of a value substantially equal to the aggregate amount of all such drawn down funds, in the form of a bond, insurance policy (which bond or insurance policy names XTO Energy as its sole beneficiary), escrow account, or other financial security acceptable to XTO Energy in its sole discretion, the proceeds of which shall only be used for P&A Obligations (as defined below) and costs incurred by XTO Energy in obtaining, maintaining and administering the replacement financial security, including attorneys’ fees and related transaction and financial institution charges.

(iv) XTO Energy shall return to the issuing financial institution funds equal to any amounts which it may draw down in error.

(v) For purposes of Section 8.04(f) and the performance bond, all of the obligations to abandon, restore and remediate the Interests and Property owned by Buyer, as contemplated by Section 9.08, are referred to collectively as the “P&A Obligations”. For purposes of this Section 8.04(f), Section 9.08 and the performance bond, evidence that a P&A Obligation has been performed shall include executed forms or other written documentation as may be required by any governmental authority under applicable law to reflect completion of a P&A Obligation (including, without limitation, forms and documentation related to plugging and abandonment activities, decommissioning activities, site clearance activities and pipeline abandonment or removal activities and completion of

remedial activities) (collectively, the “P&A Documentation”). When Buyer presents to XTO Energy P&A Documentation evidencing that all of the P&A Obligations with respect to the Interests and Property owned by Buyer have been performed, XTO Energy shall release the performance bond on or before the date that is sixty (60) days from the day of receipt of such P&A Documentation.

(g) Payment to XTO Energy. At Closing, Buyer will pay XTO Energy the net amount shown on the Closing Settlement Statement by electronic funds transfer. This amount is subject to further adjustment after Closing as provided in this Agreement. Notwithstanding any other provision of this Agreement, Buyer must make payment by the specific means stated, or XTO Energy may refuse to proceed with Closing until XTO Energy, in its sole discretion, is satisfied that it has received full payment. This right is in addition to all other rights and remedies XTO Energy may have under this Agreement, at law, or in equity.

(h) Delivery of Possession. Subject to the terms of applicable joint operating agreements, if any, the Related Agreements, and this Agreement, XTO Energy will deliver possession of the Interests to Buyer as soon as practicable after the Closing Date.

8.05 Offset of Amounts Owed to XTO Energy and Affiliates. Before Closing, XTO Energy may review all outstanding accounts between Buyer and XTO Energy and its Affiliates and include any amounts due to XTO Energy or any of its Affiliates in the Closing Settlement Statement. Buyer will pay the amounts due to XTO Energy or any of its Affiliates, if any, as a condition of Closing.

8.06 Condition Precedent. Buyer’s performance of its obligations under this Article 8 is a condition precedent to XTO Energy’s obligation to close this transaction.

8.07 Buyer’s Representation by Closing. By closing this transaction, Buyer will be deemed to represent to XTO Energy that all of Buyer’s representations under this Agreement and the Additional Instruments are true as of the Closing Date.

8.08 Insurance. XTO Energy will terminate all insurance that it has provided to cover its ownership share in the Interests on the Closing Date, except to the extent that insurance is required by or provided under a joint operating or similar agreement. If the Effective Time is before the Closing Date, the termination will be effective retroactive to the Effective Date. Buyer relinquishes and waives, on its behalf and on behalf of all persons subrogated to Buyer’s rights, all rights to claim against any insurance provided by XTO Energy. To the extent that XTO Energy, as Operator, may have obtained commercial insurance applicable to the Interests that is required by or provided under a joint operating or similar agreement, then Buyer shall take over stewardship of such insurance policies on behalf of the non-operators, if Buyer operates the Interests after the Closing Date.

8.09 Right to Terminate. Notwithstanding anything herein to the contrary, in the event that Closing has not occurred on or before October 31, 2011 for reasons not within the control of XTO Energy, XTO Energy shall have a continuing right thereafter to terminate this Agreement

by providing written notice of termination to Buyer. In the event of such termination, XTO Energy shall refund the Performance Deposit, however, subject to Article 24.

ARTICLE IX
POST-CLOSING OBLIGATIONS

9.01 Filing and Recording. XTO Energy will decide which Party will file or record the conveyancing documents in the appropriate governmental records. The recording Party will provide either the original or photocopies of the filed or recorded document, including the recording data, as agreed by the Parties, to the non-recording Party. Buyer will reimburse XTO Energy for the filing, recording, and other reasonable fees that XTO Energy incurs if XTO Energy files or records the documents.

9.02 Copies. Within sixty (60) days after the Closing Date, XTO Energy will deliver to Buyer, at Buyer’s cost and request, originals, if available, if not copies, of data and records relating to the Interests and Property as agreed by the Parties (including, without limitation, to the extent in XTO Energy’s possession and delivery to Buyer is not subject to a third party restriction, all lease files, land files, well files, gas and oil sales contract files, gas processing files, division order files, abstract, title opinion, land surveys, cores, logs, geological and geophysical information and studies, maps, hazard surveys, engineering data, studies and reports, production records, reservoir studies and evaluations (insofar as same cover and exist within the boundaries of the Interests and Properties) and other books, records, data, files, maps and accounting records, in each case to the extent related to the Interests and Properties, or used, or held for use in connection with the ownership, use, maintenance or operation thereof). In the event XTO Energy requires copies of original files that are delivered or requested by Buyer, Buyer shall pay for the costs associated with said copies. XTO Energy is not obligated to provide copies of any data or records that would not have been made available to Buyer under Section 5.01. Buyer must advise XTO Energy before Closing which data and records that it wants to be delivered or copied. If Buyer requests geophysical, proprietary seismic data, and proprietary reprocessing data or derivatives and if XTO Energy is restricted from releasing the data to Buyer, Buyer’s execution of a licensing agreement satisfactory to the third part owner of the data will be a condition of XTO Energy’s delivering the data to Buyer. For leases subject to the jurisdiction of the Bureau of Ocean Energy Management, Regulation and Enforcement (“BOEMRE”), XTO Energy will sign and deliver to Buyer, if required, a complete list of the copies of data and records delivered to Buyer (with omissions noted and explained for records required under federal regulations, but which are not available). Buyer will sign the list and submit it to the BOEMRE in accordance with applicable regulations.

If originals or the last-remaining copies of any data or records are provided to Buyer, XTO Energy may have access to them at reasonable times and upon reasonable notice during regular business hours for as long as any Interest is in effect after the Effective Time (or for 21 years in the case of a mineral fee or other non-leasehold interest or a longer period if required by law or governmental regulation). XTO Energy may, during this period and at its expense, make copies of the data and records pursuant to a reasonable request. Without limiting the generality of the two preceding sentences, for as long as any Interest is in effect after the Effective Time (or for 21 years in the case of a mineral fee or other non-leasehold interest or for a longer period if required by law or governmental regulation), Buyer may not destroy or give up possession of any

original or last-remaining copy of the data or records without first offering XTO Energy the opportunity, at XTO Energy’s expense, to obtain the original or a copy. After this period expires, Buyer must offer to deliver the data and records (or copies) to XTO Energy, at XTO Energy’s expense, before giving up possession or destroying them.

9.03 Further Assurances. Buyer and XTO Energy each will, from time to time after Closing and upon reasonable request, execute, acknowledge, and deliver in proper form any conveyance, assignment, transfer, or other instrument reasonably necessary to accomplish the purposes of this Agreement.

9.04 Post-Closing Third-Party Consents. If XTO Energy elects to close without all third-party consents and approvals, Buyer must proceed diligently after Closing to obtain and promptly provide evidence of them to XTO Energy. If any third party (including any governmental or regulatory agency) having a right to approve or reject assignment of any Interest by XTO Energy to Buyer in order for title to transfer does not approve the assignment, or if Buyer does not meet conditions imposed for approval of the assignment, after Buyer has made a good faith effort to obtain the approval or permits or to satisfy the conditions, then XTO Energy may require reassignment of those Interests for which approval or consent was not received. The Interests and Property must be in the same condition on the reassignment date as they were on the Closing Date, reasonable wear and tear excepted. Upon reassignment, XTO Energy will refund to Buyer the Allocation for each reassigned Interest, without interest, but adjusted for operating expenses and revenue attributable to the period before reassignment. Buyer will be responsible for all amounts due under contracts, including the Related Agreements, as to any Interest that requires approval for assignment, from the Effective Time forward. This obligation will end only if an Interest is reassigned under this Section 9.04.

9.05 Reassignment. For reassignment of any Interest under this Agreement, Buyer will execute and deliver to XTO Energy a reassignment by special warranty, in a form satisfactory to XTO Energy and sufficient to place XTO Energy in the same position it occupied before the assignment to Buyer. Buyer’s release and discharge of XTO Energy and its Associated Parties, its covenant not to xxx XTO Energy or its Associated Parties, and its obligations to indemnify, defend, and hold XTO Energy and its Associated Parties harmless will apply to Interests that are reassigned for the period of Buyer’s ownership, and the reassignment instrument will restate Buyer’s obligations.

9.06 Buyer’s Compliance. Buyer will comply with all rules, regulations, statutes, and laws applicable to Buyer’s ownership or operation of the Interests or Property and with all Related Agreements, insofar as they concern or pertain to the Interests.

9.07 Property Sales Accounting Agreement. Buyer will perform all its obligations under the Property Sales Accounting Agreement, including payment of rentals, shut-in payments, and minimum royalties.

9.08 Plugging and Abandoning Xxxxx; Remediation. Buyer recognizes, and will either perform or assure that performance is accomplished properly and in accordance with applicable law and the Related Agreements, all obligations to abandon, restore, and remediate the Interests

and Properties, whether arising before or after the Effective Time, including obligations, as applicable to the Interests and Properties, to:

(a) obtain plugging exceptions in Operator’s name for each Well with a current plugging exception, or permanently plug and abandon the Well;

(b) plug, abandon, and if necessary, re-abandon each Well;

(d) close all pits; and

(e) restore and remediate the surface, subsurface, and offshore sites associated with the Interests or Property.

Buyer will pay all costs and expenses associated with the obligations assumed under this Section 9.08. XTO Energy may require Buyer to prove its financial ability to perform these obligations after Closing or to provide and maintain a letter of credit, establish an escrow account, or obtain a performance bond or other financial security in an amount, in a form, and from an institution acceptable to XTO Energy to guarantee Buyer’s obligations under this Section. Pursuant to Section 8.04(d)(9), Buyer will deliver the required financial security at Closing.

9.09 Surrender or Abandonment of Interests. If Buyer decides to surrender or abandon any of the Interests after Closing, Buyer must give XTO Energy written notice of its intent at least forty-five (45) days before surrender or abandonment if XTO Energy:

(a) has retained an interest in the Interests;

(b) has other interests for which XTO Energy requires access across the Interests or Property in order to exercise its rights; or

(c) has other interests that are held by production from the Interests. XTO Energy will have thirty (30) days after receipt of Buyer’s notice to notify Buyer that it elects to require Buyer to reassign all or any part of the Interests. Reassignment will be in the manner described in Section 9.05.

ARTICLE X
TAXES

10.01 Ad Valorem Taxes. Ad valorem taxes (including production-based ad valorem taxes), real property taxes, and similar obligations imposed on the Interests and Property according to their value (“Ad Valorem Taxes”) will be apportioned between XTO Energy and Buyer as of the Effective Time. Whether the Interests and Property are valued based on the previous year’s production or any other basis, Buyer is obligated to pay the current year’s Ad Valorem Tax assessment and all subsequent Ad Valorem Taxes, subject to the following apportionment provisions. The basis of the apportionment will be the assessment for the tax year

in which the Effective Time occurs or, if that assessment is not known, then the basis of the apportionment will be the assessment for the previous tax year. If Ad Valorem Taxes have not been paid before Closing, Buyer will be credited for XTO Energy’s portion of the Ad Valorem Taxes on the Closing Settlement Statement. If they have been paid before Closing, XTO Energy will be credited for Buyer’s portion of the taxes on the Closing Settlement Statement. Buyer will be responsible for all Ad Valorem Taxes and interest that are applied to the Interests retroactively after the Effective Time.

10.02 Production Taxes. All taxes (other than Ad Valorem Taxes and income taxes) imposed on or with respect to the production of Oil, gas, or other hydrocarbons or minerals, or the receipt of proceeds from their sale (including severance, production, and excise taxes) will be apportioned between the Parties as of the Effective Time. XTO Energy will be responsible for paying or withholding all taxes that have accrued before the Effective Time or as otherwise provided in the Property Sales Accounting Agreement and for filing all statements, returns, and documents pertinent to them. Buyer will be responsible for paying or withholding all taxes that accrue or are applied retroactively after the Effective Time or as otherwise provided in the Property Sales Accounting Agreement; for filing all statements, returns, documents incident to them; and for obtaining reimbursements, if any, relating to those taxes.

10.03 Other Taxes. At Closing, XTO Energy will collect from Buyer and pay all applicable state and local sales taxes, use taxes, gross receipts taxes, business license taxes, other taxes (except taxes imposed by reason of income to XTO Energy), and fees. The taxes collected will be based on Buyer’s Allocations, as adjusted under this Agreement. Buyer will pay all state and local taxes, including penalty and interest, if any, assessed after the Effective Time against either Party with respect to this transaction or, if paid by XTO Energy, Buyer will promptly reimburse XTO Energy for amounts paid. Buyer will pay all documentary stamp taxes.

10.04 Tax-Deferred Exchange. XTO Energy may elect by notice to Buyer before the Closing Date to effect a tax-deferred exchange under Section 1031 of the Code of all or part of the Interests. If XTO Energy so elects, Buyer will accommodate XTO Energy and will execute escrow instructions, documents, agreements, or other instruments, as reasonably requested by XTO Energy, to effect the exchange; provided, however, such execution(s) shall not result in any additional cost, expense or liability to Buyer. XTO Energy may assign its rights and delegate its duties under this Agreement to an exchange intermediary that it selects, as may be necessary to effect a tax-deferred exchange.

ARTICLE XI
OIL IN STORAGE, PROCEEDS, COSTS, EXPENSES,
CLAIMS, AND DISBURSEMENTS

11.01 Oil in Storage.

(a) All Oil in storage at the Effective Time, including working inventory, belongs to XTO Energy. Title to Oil in storage for both XTO Energy-operated Interests and Interests operated by others will transfer to Buyer as of the Effective Time.

(b) XTO Energy, at its sole option, may include as “Oil in storage” all Oil in the system downstream of the wellhead at the Effective Time, including Oil in stock tanks, wash tanks, heater treaters, flowlines, and pipelines. For XTO Energy-operated Interests, at the Effective Time XTO Energy will:

(i) at its sole option, either run or gauge the Oil in storage; and

(ii) read and replace all gas meter charts.

If the Effective Time is after the Execution Date, Buyer may be present for these operations.

(c) XTO Energy will use measured Oil inventories in the Closing Settlement Statement, if available or, if not available, then estimated Oil inventories. The estimates will be based on the average month-end inventories of the three most recent calendar months prior to the Effective Time. If there is a difference between the value of the estimated Oil in storage and the value of inventories run or gauged at the Effective Time, XTO Energy may include the difference in the Final Settlement Statement.

(d) Oil inventories will be credited to XTO Energy in the Closing Settlement Statement. The assessed value of the Oil in storage will be priced, at XTO Energy’s option, at either:

(i) XTO Energy’s posted price at the Effective Time for Oil of like grade and gravity in the field where the relevant Interest is located;

(ii) if there is no XTO Energy-posted price for the field, then the average of the two highest prices, as determined by XTO Energy, posted by other purchasing companies in the field or locality where the Interest is located, for Oil of like grade and gravity, in effect at the Effective Time;

(iii) the applicable posted price, with appropriate gravity adjustments; or

(iv) the price received for the Oil from the purchaser (or an estimate of the price) or the price paid shall be a mutually agreeable negotiated price, with transportation charges deducted, where applicable.

(e) For Interests operated by others, XTO Energy will include in the Closing Settlement Statement the quantity of Oil in storage at the Effective Time as represented by the Operator or as obtained from information filed with the applicable regulatory agency. The value of Oil in storage for Interests operated by others will be determined on the same basis as that used to determine the value of Oil inventories for XTO Energy-operated Interests.

11.02 Proceeds, Costs, and Expenses.

(a) Except as otherwise provided in this Agreement and without prejudice to the provisions of the Property Sales Accounting Agreement:

(i) XTO Energy reserves all rights to proceeds, receipts, reimbursements, credits, and income attributable to the Interests and accruing before the Effective Time; and

(ii) all proceeds, receipts, credits, income, and charges attributable to the Interests and accruing after the Effective Time will be Buyer’s property and responsibility.

For accounts held in suspense or escrow at Closing, XTO Energy will pay in full the royalty accounts that were suspended because the amount due is less than the statutory minimum for payment and, as to all other accounts, will disburse funds after Closing upon proof satisfactory to XTO Energy that the money is due to the party claiming it.

(b) Except as otherwise provided in this Agreement and without prejudice to the provisions of the Property Sales Accounting Agreement, XTO Energy will make all disbursements for:

(i) payment of charges and invoices for costs and expenses accruing before the Effective Time and attributable to the Interests; and

(ii) payments necessary as the result of sales of production from the Interests occurring before the Effective Time (including disbursements out of proceeds held in suspense or escrow).

Buyer will be responsible for all payments and disbursements after the Effective Time but if XTO Energy makes any of these payments or disbursements (including rentals paid prior to the Effective time, but covering periods after the Effective Time), Buyer will reimburse XTO Energy for the amounts paid.

(c) All amounts due from one Party to the other under this Section 11.02 may be made by debits and credits in the Closing Settlement Statement and Final Settlement Statement.

11.03 Notice to Remitters of Proceeds. XTO Energy will make reasonable efforts to notify all remitters of proceeds from the sale of production of this transaction. Except as otherwise provided in the Property Sales Accounting Agreement, XTO Energy is responsible for obtaining from the remitters revenues accrued before the Effective Time, and Buyer is responsible for obtaining from the remitters revenues accruing after the Effective Time. The Parties will inform the remitters that this transaction has closed by letter-in-lieu-of-transfer order or other documents required by each remitter.

11.04 Reservation of Claims. XTO Energy reserves all Claims and rights of any kind concerning the Interests or Property against third parties that accrue before the Effective Time

(including those against overriding royalty owners, royalty owners, working-interest owners, and gas purchasers), whether discovered before or after Closing. The reservations under this Section do not include gas-production-imbalance accounts, which are the subject of Article 20.

ARTICLE XII
XTO ENERGY-OPERATED INTERESTS

12.01 Operation by XTO Energy. XTO Energy will operate the XTO Energy-operated Interests until the later of the Closing Date or the time that the applicable operating agreement, plan of unitization, or law requires. As soon as practicable thereafter, operations will be turned over to, and become the responsibility of, XTO Energy’s successor as Operator. XTO Energy is not obligated to obtain Buyer’s approval of any aspect of operations while it operates the Interests, except to the extent provided for in the Transition Services Agreement attached as Exhibit Ito be effective as of the Closing Date. Notwithstanding anything to the contrary in this Agreement, XTO Energy may cancel its applicable regulatory permits at any time and for any reason after it ceases to operate an Interest, with prior notice to the Buyer.

12.02 Charges Paid by Buyer. For the period of operation by XTO Energy from the Effective Time until the Closing, Buyer will pay XTO Energy as follows:

(a) Operation and Maintenance Expenses. A fixed monthly rate for operation and maintenance expenses and other miscellaneous costs and expenses incidental to the operation, protection, and maintenance of the Interests and Property (but excluding costs under paragraph (b) below) based on the average operation, maintenance, and miscellaneous costs and expenses for each Interest for the three-month period before the Effective Time.

(b) Other Costs. Reimbursement for workover costs, plugging, abandoning, and re-abandoning costs, CO2 purchases, prepaid items (e.g., utility charges, rentals, deposits and any other prepays excluding taxes) prorated before and after the Effective Time, and other major costs incurred by XTO Energy incidental to the operation, protection, and maintenance of the Interests and Property, on an actual-cost basis.

These charges will be included in the Closing Settlement Statement or Final Settlement Statement, as applicable. The Transition Services Agreement shall provide additional charges related to operations and accounting service post Closing.

12.03 Risk of Loss. Unless this Agreement is terminated as to an Interest, the risk of loss for damage to or destruction of the XTO Energy-operated Interests and Property associated with that Interest will pass from XTO Energy to Buyer as of the Closing Date, EVEN IF SUCH DAMAGE OR DESTRUCTION IS CAUSED IN WHOLE OR IN PART BY THE GROSS, SOLE, JOINT, CONCURRENT, ACTIVE OR PASSIVE NEGLIGENCE OF XTO ENERGY OR ANY OF ITS ASSOCIATED PARTIES OR ANY THIRD PARTY AND REGARDLESS OF WHO MAY BE AT FAULT OR OTHERWISE RESPONSIBLE UNDER ANY OTHER CONTRACT OR ANY STATUTE, RULE OR THEORY OF LAW

INCLUDING THEORIES OF STRICT LIABILITY. Any such damage or destruction will not be cause for Buyer to delay Closing or terminate this Agreement.

For purposes of this Section, a Casualty Loss shall be defined as a loss resulting from a hurricane, other weather event, or an act of God, in the Gulf of Mexico between the Execution Date and Closing, and shall not include any change in the condition of an XTO Energy-operated Interest and Property associated with that Interest arising from normal depletion, watering-out, casing collapse or sand infiltration of any well and the depreciation of property through ordinary wear and tear. If prior to Closing, XTO Energy becomes aware of a Casualty Loss associated with an XTO-Operated Interest or Property, XTO Energy shall promptly notify Buyer of the Interest and Property affected by such Casualty Loss. Prior to Closing, the Parties shall endeavor to assess the extent of the Casualty Loss and mutually agree to an adjustment to the Base Purchase Price resulting from the Casualty Loss; provided, however, if the Parties fail to mutually agree to such adjustment, XTO Energy, at its sole election shall have the option to remove the affected Interest from this Agreement and adjust the Base Purchase Price by the Allocation for that Interest. However, in the event a Casualty Loss affects the SMI 41 Field (XTO File Numbers 0000-0000-00 (OCS-G 13607 South Xxxxx Island 40 Block), 3446-001-00 (OCS-G 0000 Xxxxx Xxxxx Xxxxxx 00 Xxxxx), 0000-0000-00 (OCS-G 23840 South Xxxxx Island 44 Block), and 0000-0000-00 (OCS-G 31353 South Xxxxx Island 45 Block), as referenced on Exhibit A, referred to collectively as “SMI 41 Field”), the Parties must mutually agree to remove SMI 41 Field from this Agreement and adjust the Base Purchase Price by the Allocation for the SMI 41 Field in the event the Parties do not mutually agree to an adjustment to the Base Purchase Price resulting from such Casualty Loss. Notwithstanding anything to the contrary set forth in this Agreement, Buyer shall have, at its sole election, the right upon written notice to XTO Energy to terminate this Agreement and receive a refund of the Performance Deposit if the SMI 41 Field is removed because of a Casualty Loss.

In the event a Casualty Loss occurs between the Execution Date and the Closing Date specified in Section 8.01, as same may be extended under either Sections 8.02 or 8.03, either Party may delay Closing for the affected Interest up to sixty (60) days, unless otherwise extended by mutual agreement of the Parties, after the originally-scheduled Closing Date upon written notice to the other Party, unless XTO Energy elects to remove the affected Interest from this Agreement under and in accordance with this Section 12.03.

12.04 Selection of Operator. Upon execution of this Agreement, XTO Energy or Buyer may poll the parties to applicable joint operating agreements or plans of unitization before Closing to select a successor Operator. The poll may stipulate that XTO Energy will not resign as Operator unless Closing occurs. XTO Energy may resign as Operator under applicable regulations if Buyer does not diligently pursue its designation as Operator of the Interests that it will operate. If any such polling commenced by XTO Energy or Buyer is not completed by Closing, then it will be Buyer’s responsibility to complete such polling immediately after Closing. Buyer’s selection as Operator, whether under a joint operating or similar agreement or pursuant to applicable regulations, is not a condition of Buyer’s performance under this Agreement.

12.05 Removal of Signs. XTO Energy may either remove its name and signs from the XTO Energy-operated Interests and Property or require Buyer to do so for those Interests that it will operate. Once Buyer has become Operator, Buyer must:

(a) remove any remaining signs and references to XTO Energy from the Property or Interests promptly, but no later than the time required by applicable regulations or 45 days after XTO Energy ceases to be Operator, whichever occurs first;

(b) install signs complying with applicable governmental regulations, including signs showing Buyer as Operator of the Interests it operates; and

XTO Energy reserves a right of access to the Interests and Property after it ceases to be Operator to remove its signs and name from all Xxxxx, facilities, and Property, or to confirm that

Buyer has done so for the Interests operated by Buyer. If XTO Energy removes signs because Buyer has not done so, XTO Energy will charge its costs to Buyer, and Buyer will pay the invoice within fifteen (15) days of receipt.

ARTICLE XIII

INTERESTS OPERATED BY OTHERS

13.01 Charges Paid by Buyer. Buyer will reimburse XTO Energy for charges made by the Operator after the Effective Time and paid by XTO Energy.

13.02 Risk of Loss. Unless this Agreement is terminated as to an Interest, the risk of loss for damage to or destruction of each Interest operated by others and the Property associated with that Interest will pass from XTO Energy to Buyer as of the Closing Date, EVEN IF SUCH DAMAGE OR DESTRUCTION IS CAUSED IN WHOLE OR IN PART BY THE GROSS, SOLE, JOINT, CONCURRENT, ACTIVE OR PASSIVE NEGLIGENCE OF XTO ENERGY OR ANY OF ITS ASSOCIATED PARTIES OR ANY THIRD PARTY AND REGARDLESS OF WHO MAY BE AT FAULT OR OTHERWISE RESPONSIBLE UNDER ANY OTHER CONTRACT OR ANY STATUTE, RULE OR THEORY OF LAW INCLUDING THEORIES OF STRICT LIABILITY. Any such damage or destruction will not be cause for Buyer to delay Closing or terminate this Agreement.

option, have the option to remove the affected Interest from this Agreement and adjust the Base Purchase Price by the Allocation for that Interest. In the event a Casualty Loss occurs between the Execution Date and the Closing Date specified in Section 8.01, as same may be extended under either Sections 8.02 or 8.03, either Party may delay Closing for the affected Interest up to sixty (60) days, unless otherwise extended by mutual agreement of the Parties, after the originally-scheduled Closing Date upon written notice to the other Party, unless XTO Energy elects to remove the affected Interest from this Agreement under this Section 13.02.

ARTICLE XIV
PREFERENTIAL RIGHT TO PURCHASE OIL

XTO Energy shall have, for the life of the lease in any instrument(s) of conveyance concerning the Interests, the preferential right to purchase from time to time all or any portion of the Oil, which may be produced and saved from or allocated to the Interests conveyed by XTO Energy hereunder, except for that Oil which is used for operations upon and for the sole benefit of the Interests conveyed by this Agreement. The price to be paid shall be a mutually agreeable negotiated price, with transportation charges deducted, where applicable.

Notwithstanding anything herein to the contrary, if Buyer receives a bona fide offer from an independent third party to purchase the above Oil, which exceeds the price that XTO Energy is currently paying, then Buyer shall furnish XTO Energy with a copy of said offer and XTO Energy shall have the option (but not the obligation) to match such offer and purchase such Oil on terms identical to that contained in the offer. Notice of XTO Energy’s election to match said offer shall be provided in writing to Buyer within ten (10) working days after receipt of such notice.

Should XTO Energy, on any one or more occasions, elect not to purchase or not respond within ten (10) working days after notification by Buyer, then XTO Energy’s right to purchase Oil shall be considered temporarily waived until such third party term purchase has expired or until such time as XTO Energy is willing to match the independent third party’s offer, consistent with the cancellation notice period of said offer.

XTO Energy shall have the right to assign its preferential right to purchase to any of its subsidiaries or affiliates. Upon such assignment, the subsidiary or affiliate shall have the same rights as XTO Energy under this Article 14.

All notifications under this Article shall be sent to:

XTO Energy:		Buyer:

XTO Energy will continue to defend its own interests and provide principal counsel in an action under this paragraph for which it remains a party after the Effective Time.

(e) Buyer’s release and discharge of XTO Energy and its Associated Parties and its covenant not to xxx do not include Claims that Buyer may enforce against contractors and subcontractors for work regarding the Interests and the Properties. In addition, Buyer’s release and discharge of XTO Energy and its Associated Parties and its obligation to indemnify, defend and hold XTO Energy harmless under this Agreement does not include Claims that XTO Energy breached this Agreement_ Any such Claims will be resolved in accordance with Article 17.

16.05 Buyer’s Duty to Defend. Buyer acknowledges that its obligations to indemnify, defend, and hold XTO Energy and its Associated Parties harmless under this Agreement include obligations to pay the attorneys’ fees and court and other costs incurred by XTO Energy and its Associated Parties in defending all Claims. As to each Claim and Liability, XTO Energy, at its sole option, may elect to:

(a) manage its own defense, in which event Buyer will reimburse XTO Energy and its Associated Parties for all attorneys’ fees and court and other costs reasonably incurred in defending a claim, upon delivery to Buyer of invoices for these fees and costs; or

(b) tender its defense as to any Claim to Buyer, in which event Buyer will be responsible for all aspects of defending the Claim at issue and resulting Liabilities.

16.06 Buyer’s Waiver of Consumer Rights Under the Texas Deceptive Trade Practices Consumer Protection Act and Other Consumer Protection Laws. AS PARTIAL CONSIDERATION TO XTO ENERGY TO ENTER INTO THIS AGREEMENT, TO THE EXTENT THAT THE TEXAS DECEPTIVE TRADE PRACTICES CONSUMER PROTECTION ACT IS APPLICABLE TO THIS TRANSACTION, BUYER CAN AND DOES EXPRESSLY WAIVE ITS RIGHTS UNDER THE TEXAS DECEPTIVE TRADE PRACTICES CONSUMER PROTECTION ACT, SECTIONS 17.41 THROUGH 17.63, TEXAS BUSINESS AND COMMERCE CODE, A LAW THAT GIVES CONSUMERS SPECIAL RIGHTS AND PROTECTIONS. AFTER CONSULTATION WITH AN ATTORNEY OF ITS OWN SELECTION, BUYER VOLUNTARILY CONSENTS TO THIS WAIVER. IN ADDITION, BUYER WAIVES ITS RIGHTS UNDER ALL OTHER CONSUMER PROTECTION LAWS IN OTHER STATES APPLICABLE TO THIS TRANSACTION THAT MAY BE WAIVED BY THE PARTIES.

16.07 Retroactive Effect. Buyer acknowledges that its obligations to release, discharge, defend, and hold XTO Energy and its Associated Parties harmless and its covenant not to xxx XTO Energy or its Associated Parties apply to matters occurring or arising before the Execution Date to the extent provided in this Agreement.

16.08 Inducement to XTO Energy. BUYER ACKNOWLEDGES THAT IT EVALUATED ITS OBLIGATIONS UNDER THIS ARTICLE 16 BEFORE IT DETERMINED AND SUBMITTED ITS BID FOR THE INTERESTS AND THAT ITS ASSUMPTION OF THESE OBLIGATIONS IS A MATERIAL INDUCEMENT TO XTO ENERGY TO ENTER INTO THIS AGREEMENT WITH, AND CLOSE THE SALE TO, BUYER.

ARTICLE XVII
ALTERNATE DISPUTE RESOLUTION AND ARBITRATION

17.01 General.

(a) This Article 17 applies to any dispute between the Parties, arising at any time, that is not subject to Buyer’s release and discharge of XTO Energy and its Associated Parties or Buyer’s covenant not to xxx XTO Energy or its Associated Parties or is not specifically excluded under this Article 17_ Whether a dispute is subject to Buyer’s release, discharge, or covenant not to xxx or to this Article (or is excluded from this Article by its terms), and whether there is a contract between the Parties, are issues that will be resolved under the alternate dispute resolution and arbitration provisions of this Article 17.

(b) As to the disputes subject to this Article 17, any Claim or controversy of whatever nature, including an action in tort or contract or a statutory action (“Disputed Claim”), or the arbitrability of a Disputed Claim, will be resolved under the terms, conditions, and procedures of set forth in this Article 17 and will be binding on both Parties and their respective successors and assigns. Neither Party may prosecute or commence any suit or action against the other Party relating to any matters that are subject to this Article 17, except as provided in this Article 17.

(c) XTO Energy will determine, at its sole option, whether a Claim filed by a third party against Buyer or XTO Energy will be subject to this Article.

ARTICLE XVIII
ENVIRONMENTAL MATTERS

18.01 Buyer’s Acknowledgment Concerning Possible Contamination of the Interests and Property. Buyer is aware that the Interests and Property have been used for exploration, development, and production of oil and gas and that there may be petroleum, produced water, wastes, or other materials located on or under the Property or associated with the Interests. Equipment and sites included in the Interests or Property may contain asbestos, hazardous substances, or NORM. NORM may affix or attach itself to the inside of Xxxxx, materials, and equipment as scale, or in other forms; the Xxxxx, materials, and equipment located on the Property or included in the Interests may contain NORM and other wastes or hazardous substances; and NORM-containing material and other wastes or hazardous substances may have been buried, come in contact with the soil, or otherwise been disposed of on the Property. Special procedures may be required for the remediation, removal, transportation, or disposal of wastes, asbestos, hazardous substances, and NORM from the Interests and the Property.

BUYER WILL ASSUME ALL LIABILITY FOR THE ASSESSMENT, REMEDIATION, REMOVAL, TRANSPORTATION, AND DISPOSAL OF WASTES, ASBESTOS, HAZARDOUS SUBSTANCES, AND NORM FROM THE INTERESTS AND PROPERTY AND ASSOCIATED ACTIVITIES AND WILL CONDUCT THESE ACTIVITIES IN ACCORDANCE WITH ALL APPLICABLE LAWS AND REGULATIONS, INCLUDING ENVIRONMENTAL LAWS.

18.02 Adverse Environmental Conditions.

(a) Buyer will have until ten (10) days before the Closing Date to notify XTO Energy of any material adverse environmental condition of the Interests or Property that Buyer finds unacceptable and provide evidence of the condition to XTO Energy. An environmental condition is a material adverse environmental condition (“Condition”) only if all the following criteria are met:

(i) the environmental condition is required to be remediated on the Execution Date under the Environmental Laws in effect on the Execution Date;

(ii) the total of the cost to remediate all environmental conditions identified by Buyer to levels required by the Environmental Laws in effect on the Execution Date is reasonably estimated to be more than one percent (1%) of the Base Purchase Price; and

(iii) the environmental condition was not disclosed to or known by Buyer before the Execution Date.

(b) XTO Energy will have thirty (30) days after receipt of Buyer’s notice under the preceding paragraph, or until five (5) days before the Closing Date if it determines that an adverse environmental condition (whether material or not) may exist with respect to an Interest or Property, to elect any of the following:

(i) adjust the Allocation for an Interest by a mutually acceptable amount reflecting XTO Energy’s proportionate share, based on its working

interest, of the cost reasonably estimated to remediate a Condition affecting the Interest;

(ii) remove the affected Interest from this Agreement and adjust the Base Purchase Price by the Allocation for the affected Interest;

(iii) remedy, or agree to remedy, the Condition, as provided below; or

(iv) terminate this Agreement.

XTO Energy may delay Closing until the end of this thirty-day period, which delay will be in addition to and under the same terms as XTO Energy’s right to delay Closing under Section 8.03.

(c) If XTO Energy and Buyer agree to adjust an Allocation because of a Condition, the amount of the adjustment will be the cost to remediate the Condition, but only to the level required by the Environmental Laws in effect on the Execution Date. XTO Energy may require Buyer to remit the full Allocation at Closing, without adjustment for the Condition, but if it does so, it will pay the amount of the adjustment to Buyer when the remediation is complete under applicable law. If the cost to remediate exceeds the amount of the adjustment, Buyer will pay the additional costs to remediate the Condition as required by applicable law.

18.03 Remediation. If XTO Energy agrees with Buyer to remediate a Condition or is required by a governmental or regulatory agency to remediate a Condition, the following will govern the remediation:

(a) XTO Energy will be responsible for all negotiations and contacts with federal, state, and local agencies and authorities with regard to the Condition or remediation. Buyer may not make any independent contacts with any agency, authority, or other third party with respect to the Condition or remediation and will keep all information regarding the Condition and remediation confidential, except in each instance to the extent required by applicable law.

(b) XTO Energy will remediate the Condition to the level agreed upon by XTO Energy and Buyer, but in no event will XTO Energy be required to remediate the Condition beyond the level required by the Environmental Laws in effect on the Execution Date.

(c) Buyer will grant and warrant access to the Interests and entry on the Property after Closing to XTO Energy, its Associated Parties, and third parties conducting assessments or remediation, to the extent and as long as necessary to conduct and complete the assessment or remediation work, to remove equipment and facilities, and to perform any other activities reasonably necessary in connection with assessment or remediation.

(d) Buyer will use its best efforts not to interfere with XTO Energy’s ingress and egress or assessment or remediation activities. XTO Energy will make reasonable

efforts to perform the work so as to minimize disruption to Buyer’s business activities and to the Interests and the Property.

(e) XTO Energy will continue remediation of the Condition until the first of the following occurs:

(i) the appropriate governmental authorities provide written notice to XTO Energy or Buyer that no further remediation of the Condition is required; or

(ii) XTO Energy determines that the Condition has been remediated to the level required by the Environmental Laws or as agreed by the Parties.

Upon the occurrence of either (1) or (2) above, XTO Energy will notify Buyer that remediation of the Condition is complete and provide a copy of the notification described in (1) above, if applicable. Upon delivery of XTO Energy’s notice, XTO Energy will be released from all liability and have no further obligations under any provisions of this Agreement in connection with a Condition.

(f) Until XTO Energy completes remediation of a Condition, XTO Energy and Buyer will each notify the other of any pending or threatened Claim, action, or proceeding by any authority or private party that relates to or would affect the environmental condition, the assessment, or the remediation of the Interests or Property.

(g) After delivery of possession or Closing (whichever occurs first) and before XTO Energy has completed remediation of a Condition, if a leak, spill, or discharge of any material or substance (“Occurrence”) occurs on the Property or Interests, or any part of them, Buyer will promptly notify XTO Energy and act promptly to minimize the effects of the Occurrence. If a spill, leak or discharge occurs and XTO Energy determines that it may affect the area where XTO Energy is conducting remediation or assessment, Buyer will hire a consultant (who must be acceptable to XTO Energy) to assess the effect of the occurrence on the environmental condition of the Property, Interest, and XTO Energy’s remediation work and the cost of the additional work required as the result of the Occurrence. Unless the Occurrence was caused solely by XTO Energy, Buyer will be responsible for the incremental cost of remediating the impact of the Occurrence. If XTO Energy’s remediation is expanded to incorporate remediation of the Occurrence, Buyer will promptly pay its share of costs and expenses to XTO Energy as the work is performed, within thirty (30) days of receipt of invoices for the work (with supporting documentation). Payments not made timely will bear interest at a rate of twelve percent (12%) per annum or the maximum lawful rate, whichever is less, compounded daily from the date of Buyer’s receipt of the invoice until paid.

If the cost of the additional work equals or exceeds the cost which would have been incurred but for the Occurrence, XTO Energy will pay Buyer the cost that would have been incurred by XTO Energy to complete the remediation but for the Occurrence. As consideration for this payment, Buyer will accept the environmental condition of the Property and Interests as they exist on the date of the payment, assume full responsibility

for remediating the Property and Interests and related off-site contamination in accordance with this Agreement, and agree to release, not to xxx, indemnify, hold harmless, and defend XTO Energy and its Associated Parties as to Claims and Liabilities arising from the Occurrence to the same extent as described in Article 16.

(h) If XTO Energy undertakes remediation as to any Interest in which XTO Energy’s ownership was less than one hundred percent (100%), Buyer will xxxx the other working interest owners for their share of the remediation expenses. Regardless of whether Buyer recoups any amount from the other working interest owners, Buyer will refund to XTO Energy, within sixty (60) days of each XTO Energy invoice, with documentation, any amounts expended by XTO Energy over the amount formerly attributable to XTO Energy’s working interest share.

(i) If XTO Energy will assess or remediate the Interests or Property after Closing, the Assignment and Xxxx of Sale or other recordable instrument will restate the rights and obligations of this Section 18.03.

18.04 Disposal of Materials, Substances, and Wastes; Compliance with Law. Buyer will store, handle, transport, and dispose of or discharge all materials, substances, and wastes from the Interests and Property (including produced water, drilling fluids, NORM, and other wastes), whether present before or after the Effective Time, in accordance with applicable local, state, and federal laws and regulations. Buyer will keep records of the types, amounts, and location of materials, substances, and wastes that are stored, transported, handled, discharged, released, or disposed of onsite and offsite. When any lease terminates, an interest in which has been assigned under this Agreement, Buyer will undertake additional testing, assessment, closure, reporting, or remedial action with respect to the Interests or Property affected by the termination as is necessary to satisfy all local, state, or federal requirements in effect at that time and necessary to restore the Property or Interests.

ARTICLE XIX
BUYER’S REPRESENTATIONS

19.01 Representations Not Exclusive. Buyer’s representations under this Article are in addition to its other representations under this Agreement and the Additional Instruments.

19.02 Securities Laws.

(a) Buyer acknowledges that the solicitation of an offer for and the sale of the Interests by XTO Energy has not been registered under any securities laws.

(b) Buyer intends to acquire the Interests for its own benefit and account and is not acquiring the Interests with the intent of distributing fractional undivided interests in them or otherwise selling them in a manner that would be subject to regulation by federal or state securities laws. If Buyer sells, transfers, or otherwise disposes of the Interests or fractional undivided interests in them in the future, it will do so in compliance with applicable federal and state laws.

(c) Buyer represents that at no time has it been presented with or solicited by or through any public promotion or other form of advertising in connection with this transaction.

19.03 Basis of Buyer’s Decision. Buyer represents that:

(a) it has reviewed and investigated the Interests and Property to its satisfaction in order to enter into this Agreement;

(b) it has evaluated the Interests and Property to its satisfaction and has made an informed decision, as a prudent and knowledgeable purchaser, to acquire the Interests and Property;

(d) it has evaluated the merits and risks of purchasing the Interests and has formed an opinion based solely upon its knowledge and experience and not in reliance on any statements or actions by XTO Energy or its Associated Parties; and

(e) it will acquire the Interests and Property “as is, where is,” and with all faults.

19.04 Material Factor. Buyer acknowledges that its representations under this Article, the rest of this Agreement, and the Additional Instruments are a material inducement to XTO Energy to enter into this Agreement with, and close the sale to, Buyer.

ARTICLE XX
GAS IMBALANCES

20.01 XTO Energy’s and Buyer’s Respective Obligations. For those Interests with cumulative gas-production-imbalance accounts among working interest owners, Buyer acknowledges that the amounts are derived from either Operator’s statements or XTO Energy’s estimates based upon current production, prior sales history, and contract information; were provided to Buyer before the Execution Date; and were taken into consideration in Buyer’s calculation of the Base Purchase Price and the Allocations. After the Effective Time, all benefits, obligations, and liabilities associated with these gas-production-imbalance accounts and related agreements will accrue to and become Buyer’s responsibility. Buyer will assume XTO Energy’s overproduced or underproduced position as of the Effective Time and subject to the other provisions of this Agreement, unless the operating agreement, plan of unitization, or gas balancing agreement for an Interest provides for the cash settlement of gas-production-imbalance accounts when the Interest is assigned, in which event XTO Energy reserves the gas-production-imbalance account and the right to the cash settlement. XTO Energy specifically reserves certain of the gas imbalance accounts as same are identified on Exhibit E for which Buyer shall have no responsibility or liability.

Buyer represents that in calculating the Base Purchase Price and its Allocations, it has considered XTO Energy’s procedures for paying royalties and severance taxes with regard to each gas-production-imbalance account.

20.02 Settlement.

(a) If either (1) before Closing, or (2) on the later of XTO Energy’s preparation of the Final Settlement Statement or one hundred and fifty (150) days after Closing, either Party determines that a Material Difference (as defined below) exists between the total of the gas-production-imbalance accounts represented in Exhibit E and the total of the gas-production-imbalance accounts as of the Effective Time, then the Base Purchase Price will be adjusted if there is a Material Difference. The value of the difference will be calculated by multiplying the volume difference by $4.38 per Mcf (thousand cubic feet). A “Material Difference” exists if the absolute value of the difference exceeds $100,000.00.

(b) Regardless of whether a Material Difference exists, if the difference between the represented and actual gas-production imbalance account for an Interest exceeds $100,000.00, then XTO Energy, at its sole option, may withdraw that Interest from this Agreement and adjust the Base Purchase Price by the Allocation for the Interest. The difference in the gas-production-imbalance account for the withdrawn Interest will not be used to determine whether a Material Difference exists.

(c) If a Material Difference identified before Closing exceeds one percent (1%) of the Base Purchase Price, then either Party may, upon written notice to the other, terminate this Agreement. Before terminating this Agreement, however, XTO Energy and Buyer will each make a good-faith effort to negotiate a settlement. If this Agreement is terminated under this Section 20.02, XTO Energy will refund the Performance Deposit to Buyer.

ARTICLE XXI
FINAL SETTLEMENT STATEMENT

XTO Energy will prepare a final settlement statement and submit it to Buyer within one hundred and fifty (150) days after the Closing Date (the “Final Settlement Statement”). The Final Settlement Statement will deduct royalties, operating expenses, taxes, overhead, and other amounts due to XTO Energy from amounts due to Buyer as provided in this Agreement, with adjustments as necessary for items identified after Closing. XTO Energy may set off any resulting amount due to Buyer against amounts that Buyer may otherwise owe to XTO Energy or its Affiliates when the Final Settlement Statement is prepared.

Buyer must respond in writing with objections and proposed corrections within thirty (30) days of receiving the Final Settlement Statement. If the Parties cannot resolve their differences within ninety (90) days of XTO Energy’s receipt of Buyer’s objections, then the alternate-dispute-resolution and arbitration procedures of Article 17 will be triggered. If Buyer does not respond to the Final Settlement Statement by signing or objecting in writing within the 30-day period, the statement will be deemed approved by Buyer. After approval of the Final

Settlement Statement, XTO Energy will send a check or invoice to Buyer for the net amount. If payment is not made within thirty (30) days of Buyer’s receiving the invoice, the amount due may, at XTO Energy’s option, bear interest at a rate of twelve percent (12%) percent per annum or the maximum lawful rate, whichever is less, compounded daily from the date of Buyer’s receipt of the invoice until paid. Inquiries regarding the Final Settlement Statement must be in writing, addressed to:

Such option to terminate shall not be exercised by XTO Energy unless and until XTO Energy has provided Buyer with written notice of its default or failure and Buyer has failed to remedy such fault or render such performance within thirty (30) days of its receipt of such written notice.

ARTICLE XXV

Buyer will promptly pay to the appropriate government agency all filing fees required of “acquiring persons” under the Act. Notwithstanding anything to the contrary in this Agreement, the Execution Date of this Agreement will be the date of XTO Energy’s notice to Buyer that, in the opinion of XTO Energy’s counsel, this transaction complies with the Act and the rules and regulations of the Federal Trade Commission and the Department of Justice.

WHEREAS, Principal and Obligee have entered into that certain Purchase and Sale Agreement dated effective as of August 1, 2011 (hereinafter called the “Agreement”), which Agreement is by reference made a part hereof and which provides for the sale and assignment from Obligee to Principal of the interests of Obligee in certain oil and gas leases and properties, including the oil and gas leases described on Annex 1 to this Performance Bond (“Bond”), all as more particularly described in the Agreement (collectively, the “Leases” and each individually, the “Lease”), together with all rights and obligations in connection therewith, and also provides for the sale and assignment to Principal of all xxxxx, platforms, facilities, equipment and pipelines existing on the Leases as of the date of the Agreement, including the xxxxx described on Annex 2 (collectively, the “Xxxxx” and individually, the “Well”) (the Leases, Xxxxx and such platforms, facilities, equipment and pipelines, being collectively referred to as the “Properties” and each as “Property”); and

WHEREAS, Principal and Surety agree that notwithstanding the subsequent termination of any of the Leases, whether by operation of law or otherwise, this Bond shall remain in full force and effect until Principal has presented satisfactory evidence to Obligee, as set forth below, that all P&A Obligations (as such term is defined below) have been performed and discharged; and

WHEREAS, as used in this Bond, the term “P&A Obligations” means all obligations and liabilities of Principal to abandon, restore and remediate the Properties, whether arising before or after August 1, 2011 (the “Effective Time”), including obligations, as applicable to the Properties, to: (a) obtain plugging exceptions in the operator’s name for each Well with a current plugging exception, or permanently plugging and abandoning a Well; (b) plug, abandon, and if necessary, re-abandon each Well; (c) remove all equipment and facilities, including flowlines, pipelines and platforms; (d) close all pits; and (e) restore and remediate the surface, subsurface and offshore sites associated with the Properties; and

WHEREAS, Principal has agreed to deliver to Obligee this Bond, executed by Principal and Surety, at the Closing as defined and contemplated by the Agreement; and

WHEREAS, Surety represents that it is duly authorized by the proper public authorities to transact the business of indemnity and suretyship in the state where it executed this Bond, and represents that it is qualified to be surety and guarantor on bonds and undertakings, which certificate has not been revoked; and

WHEREAS, Surety represents that it has duly executed a power of attorney, appointing the hereafter named representative as its duly authorized deputy, as the true and lawful attorney-in-fact of such Surety, upon whom may be served all lawful process in any action or proceeding against such Surety in any court or before any officer, arising, out of or founded upon this Bond or any liability hereunder, and does hereby agree and consent that such service, when so made, shall be valid service upon it, and that such appointment shall continue in force and effect and be irrevocable so long as any liability against it remains outstanding hereunder;

PROVIDED, HOWEVER, whenever the Principal shall present to Obligee satisfactory evidence that all of the P&A Obligations have been performed (and as set forth in the Agreement, such satisfactory evidence shall comprise executed forms or other written documentation as may be required by any governmental authority under applicable law to reflect completion of the P&A Obligations, including, without limitation, forms and documentation relating to plugging and abandonment activities,

decommissioning activities, site clearance activities and pipeline abandonment or removal activities and completion of remedial activities), then this Bond shall be null and void; otherwise, it shall remain in full force and effect in the amount as provided.

In the event Principal fails to carry out its obligations to bear the cost and expense to perform the P&A Obligations for a Property or certain identified Properties, and Obligee has presented to Surety a written notice that Principal is in default of its obligation under the terms of the Agreement, and such condition has persisted for thirty (30) days after written notice of such default has been given by certified mail to Principal and Surety, Surety shall, within fifteen (15) days of such presentations: 1) Pay to Obligee an amount equal to the actual costs for performing the P&A Obligations with respect to the Property or identified Properties in an amount up to, but not exceeding, the maximum penal amount of this obligation and the penal amount of this obligation shall be further reduced by the amount of this obligation; or 2) Commence the necessary operations to perform the P&A Obligations with respect to the Property or identified Properties as set forth in the Agreement.

In the event Obligee commences or completes the P&A Obligations with respect to a Property or identified Properties upon Principal’s default under the terms of the Agreement, Surety’s obligations shall remain the same as set forth in this Bond regarding payment to Obligee as set forth above.

If Surety shall decide, upon default by Principal, to commence, or cause to be commenced, the performance of the aforementioned P&A Obligations, said performance shall continue until such time as the P&A Obligations have been met, thereby reducing the penal amount as set forth herein. Surety agrees to indemnify, defend, and hold harmless Obligee, its directors, and agents from all claims, demands, and causes of action for personal injury, death, property and/or environmental damage resulting in whole or in part from Surety’s or Surety’s contractors’ negligence, whether joint (including with Obligee or Principal) active, passive, concurrent or sole, or willful misconduct with respect to the performance of the P&A Obligations, if and only if Surety elects, as stated herein, to commence the aforementioned P&A Obligations in lieu of payment to Obligee.

Surety consents to be sued in any court in the State of Texas, hereby irrevocably submitting itself to the jurisdiction of said court. No amendment of or supplement to the terms or provisions of the Agreement or of the Exhibits attached thereto shall release Principal and Surety or either of them from their liability under this Bond. Notice to Surety of any such amendment or supplement is hereby waived, except to the extent that is herein provided.

No forbearance of Obligee, to Principal, shall release Principal and Surety from their liability under this Bond except where Obligee agrees to reduce the penal amount as provided above. No assignment of the Agreement or of the Property by the Principal, its successors and assigns, and no assignment of the Agreement by operation of law or consent of Obligee or otherwise shall in any degree relieve Principal and Surety of their obligations under this Bond except as provided herein. No delay, neglect or failure of

Obligee to proceed promptly to enforce the Agreement or to proceed promptly in case of default on the part of Principal or Surety shall in any degree relieve Principal and Surety of their obligations under this Bond except as herein stated.

No assignment, in whole or in part, of the Agreement or of the Properties by Principal, its successors and assigns, and no delay, neglect or failure of the Obligee to proceed promptly to enforce the Agreement or to proceed promptly in the premises in case of any default on the part of Principal shall in any degree relieve Principal and Surety or either of their obligations under this Bond.

HOWEVER, if upon assignment, in whole or in part, of the Agreement or the Property or any Well and facilities thereon by Principal, its successors or assigns, Principal may cause its assignee to post security, in the form of a bond or other acceptable security from Surety, or a surety acceptable to Obligee, covering the same obligations as stated herein as to the assigned interest (“Transferee Bond”). The penal sum provided for in the Transferee Bond with respect to such assigned Properties shall be in an amount equal to the estimated cost to perform the P&A Obligations with respect to the assigned Property, which cost estimate shall be subject to Obligee’s approval.

No right or action shall accrue on this Bond to or for the use of any person or corporation other than Principal, Obligee, their respective successors and assigns.

NOW THEREFORE, Principal and Obligee agree that any dispute, claim, or controversy concerning the interpretation of this Bond or the Agreement or any party’s compliance with the terms of this Bond shall be resolved in accordance with the terms, conditions, and procedures in Article 17 of the Agreement and each agrees not to prosecute or commence any suit or action against the other(s) relating to any such matters.

This Bond is subject to the provisions of Section 8.04(f) of the Agreement including, without limitation, the redetermination provisions that may serve to adjust the penal sum provided for herein and the ability of Obligee to draw on the Bond, in whole or in part, as expressly provided for therein. Any such redetermination shall not include estimated costs with respect to P&A Obligations for which a Transferee Bond has been obtained and approved by Obligee. Obligee will accept such Transferee Bond as financial security for the assigned Property. Further, as provided in Section 8.04(f)(1) of the Agreement, when it is determined that the estimated costs of the total remaining liabilities of Principal with respect to the P&A Obligations is less than $3,000,000.00, then this Bond shall be null and void and Obligee and Principal shall execute such documentation as is reasonably necessary in order to release and relinquish the Bond, which documentation will b executed promptly but in any event not less than sixty (60) days of being presented for execution.

In the event of a conflict or inconsistency between the terms and provisions of this Bond and those set forth in the Agreement, as between Principal and Obligee, the terms and provisions of the Agreement shall control.
