TITLE MATTERS

5.1 Title Examination Period. Provided that Seller timely provides access to the Records and other materials as contemplated in Section 7.1, the “Title Examination Period” will commence on the date of this Agreement and end at 5:00 P.M. CDT on August 22, 2011.

5.2 Title Defects. A Property shall be deemed to have a “Title Defect” if Seller is found to have less than Defensible Title and it is reasonably estimated to (a) require an expenditure in excess of $10,000.00 to remedy or (b) reduce the value of such Property by an amount in excess of $10,000.00. For purposes of this Agreement, the term “Defensible Title” shall mean such title of Seller that, subject to and except for the Permitted Encumbrances:

(a) with respect to any Property:

(1) entitles Seller to receive not less than the percentage set forth in Exhibit E as the net revenue interest for such Property of all Hydrocarbons produced, saved and marketed from such Property, all without reduction of such interest throughout the duration of the life of such Property, as to all of the depths listed on Exhibit A for such Property, and if no depths are listed, then as to all depths;

(2) obligates Seller to bear the percentage of the costs and expenses relating to the maintenance, development and operation of such Property not greater than the working interest for such Property shown in Exhibit E as to all of the depths listed on Exhibit A for such Property, and if no depths are listed, then as to all depths, without increase throughout the duration of the life of such Property, except (1) as set forth therein, (2) increases, after the date of this Agreement, resulting from contribution requirements with respect to defaulting co-owners under applicable operating agreements, and (3) increases to the extent that they are accompanied by a proportionate increase in Seller’s corresponding net revenue interest set forth in Exhibit E;

(b) is free and clear of all liens, encumbrances, encroachments, charges, claims, burdens and defects;

(d) is filed of record so as to be sufficient against competing claims of bona fide purchasers for value without notice or other Persons entitled to protection of applicable recording laws; and

(e) permits Seller and its assigns and designees rights of ingress and egress over the Properties for purposes of oil and gas exploration, development, gathering, and production.

5.3 Notice of Title Defects. If Buyer discovers any Title Defect during the Title Examination Period, Buyer shall promptly notify Seller prior to the expiration of the Title Examination Period. To be effective, such notice shall be in writing and shall include (a) a description of the alleged Title Defect, (b) each of the Properties affected (each, a “Title Defect Property”), (c) the value of each Title Defect Property (which shall be the Allocated Value), (d) documentation sufficient to reasonably support and explain the asserted Title Defect, and (e) the amount which Buyer reasonably believes to be the Title Defect Amount resulting from the alleged Title Defect and the computations and information upon which Buyer’s belief is based.

5.4 Remedies for Title Defects. Seller shall have the option, but not the obligation, to attempt to cure any Title Defect prior to Closing. In the event that any Title Defect is not cured to Buyer’s reasonable satisfaction on or before Closing, (i) the Purchase Price shall be reduced by an amount (the “Title Defect Amount”) determined pursuant to Section 5.6 and limited pursuant to Section 5.5, (ii) the Parties shall proceed to Closing, (iii) each Title Defect Property

shall be conveyed by Seller to Buyer subject to such Title Defect and (iv) Buyer shall pay to Seller the Purchase Price as so adjusted; provided, however, if the sum of all Title Defect Amounts and all Environmental Defect Amounts determined prior to Closing is equal to or exceeds $1,000,000.00, then either Party shall have the right to terminate this Agreement prior to Closing.

5.5 Limitations. Notwithstanding anything herein to the contrary, (i) in no event shall there be any adjustments to the Purchase Price or other remedies under this Agreement for any Title Defect if the sum of all Title Defect Amounts and all Environmental Defect Amounts does not exceed $100,000.00 (the “Defect Deductible”), and (ii) in the event that the sum of all Title Defect Amounts and all Environmental Defect Amounts exceeds the Defect Deductible, then any adjustments to the Purchase Price for Title Defects shall be applicable only to the portion that exceeds the Defect Deductible.

5.6 Title Defect Amount. The Title Defect Amount resulting from a Title Defect shall be the amount by which the Allocated Value of each Title Defect Property is reduced as a result of the existence of such Title Defect and shall be determined in accordance with the following terms and conditions:

(a) if Buyer and Seller agree on the Title Defect Amount, then that amount shall be the Title Defect Amount;

(b) if the Title Defect is an encumbrance that is undisputed and liquidated in amount, then the Title Defect Amount shall be the amount necessary to be paid to remove the Title Defect from the Title Defect Property;

(c) if the Title Defect represents a discrepancy between (i) the net revenue interest for any Property and (ii) the net revenue interest stated in Exhibit E for such Property and the corresponding working interest stated in Exhibit E for such Property is decreased in the same or greater ratio than the decrease in such net revenue interest, then the Title Defect Amount shall be the product of the Allocated Value of such affected Property multiplied by a fraction, the numerator of which is the net revenue interest decrease and the denominator of which is the net revenue interest stated in Exhibit E;

(d) if the Title Defect represents an obligation upon, encumbrance upon or other defect in title to the Title Defect Property of a type not described above, the Title Defect Amount shall be determined by taking into account the Allocated Value of the Title Defect Property, the portion of the Title Defect Property affected by the Title Defect, the legal effect of the Title Defect, the potential economic effect of the Title Defect over the life of the Title Defect Property, the values placed upon the Title Defect by Buyer and Seller and such other reasonable factors as are necessary to make a proper evaluation; provided, however, that if such Title Defect is reasonably capable of being cured, the Title Defect Amount shall not be greater than the reasonable cost and expense of curing such Title Defect;

(e) the Title Defect Amount with respect to each Title Defect Property shall be determined without duplication of any costs or losses included in another Title Defect Amount;

(f) if Seller and Buyer are unable to agree upon any Title Defect, Title Defect Amount or adjustment under this Section 5.6, Seller and Buyer shall, in good faith, mutually agree upon an attorney experienced in oil and gas law licensed to practice law in the State of Texas as the arbiter of the alleged Title Defect or Title Defect Amount, whose decision on all such matters must be rendered within ten (10) Business Days of the date of his or her designation, and will be final and binding on the Parties. The costs and expenses of the arbitrator shall be shared one-half by Seller and one-half by Buyer; and

(g) notwithstanding anything to the contrary in this Section 5.6, the aggregate Title Defect Amounts attributable to the effects of all Title Defects upon a Title Defect Property shall not exceed the Allocated Value of such Title Defect Property.

ARTICLE VI

6.2 Environmental Defect.

6.3 Notice of Environmental Defects. If Buyer discovers any Environmental Defect during the Environmental Examination Period, Buyer shall promptly notify Seller prior to the expiration of the Environmental Examination Period. To be effective, such notice shall be in writing and shall include (a) a description of the alleged Environmental Defect, (b) the Properties affected (each, an “Environmental Defect Property”), (c) the value of each Environmental Defect Property (which shall be the Allocated Value of such Property), (d) documentation sufficient to reasonably support the asserted Environmental Defect(s), and (e) the amount which Buyer reasonably believes to be the Lowest Cost Response to cure the alleged Environmental Defect and the computations and information upon which Buyer’s belief is based.

6.4 Remedies for Environmental Defects. Seller shall have the option, but not the obligation, to attempt to cure any Environmental Defect, to Buyer’s reasonable satisfaction, prior to Closing, and to the extent necessary, the Closing Date shall be extended by a period necessary to allow for the cure of such Environmental Defects to Buyer’s reasonable satisfaction. Notwithstanding anything herein to the contrary, the Closing Date shall be extended only as to

that Property or Properties that are subject to such Environmental Defect curative. In the event that any Environmental Defect is not cured on or before Closing, then, at the option of Buyer, for each such uncured Environmental Defect:

(a) the Purchase Price shall be reduced by an amount mutually agreed upon by Seller and Buyer, in which event (subject to the other terms of this Agreement) the Parties shall proceed to Closing, each Environmental Defect Property shall be conveyed by Seller to Buyer subject to such Environmental Defect and Buyer shall pay to Seller the Purchase Price as so adjusted (such adjustment being herein referred to as the “Environmental Defect Amount”); or

(b) Seller shall retain the Environmental Defect Property and reduce the Purchase Price by an amount equal to the Allocated Value (or portion thereof allocable thereto) of each Environmental Defect Property, in which event (subject to the other terms of this Agreement) the Parties shall proceed to Closing, the Environmental Defect Property shall be retained by Seller and Buyer shall pay to Seller the Purchase Price as so adjusted;

provided, however, if (i) Seller has chosen to cure an Environmental Defect and extend the Closing Date as provided above and (ii) Seller shall not have cured such Environmental Defect to Buyer’s reasonable satisfaction by September 15, 2011, then (1) if the Parties can agree on an Environmental Defect Amount, the procedures in Section 6.4(a) shall be followed, or (2) if the Parties cannot agree on an Environmental Defect Amount, then the procedures in Section 6.4(b) shall be followed. In addition to the foregoing remedies, if the sum of all Environmental Defect Amounts and Title Defect Amounts hereunder is equal to or exceeds $1,000,000.00, then either Party shall have the right to terminate this Agreement.

6.5 Limitations. Notwithstanding anything to the contrary, (a) in no event shall there be any adjustments to the Purchase Price or other remedies under this Agreement for any Environmental Defect if the sum of all Environmental Defect Amounts and Title Defect Amounts does not exceed the Defect Deductible, (b) in the event that the sum of all Environmental Defect Amounts and Title Defect Amounts exceeds the Defect Deductible, then any adjustments to the Purchase Price for Environmental Defects shall be applicable only to the portion that exceeds the Defect Deductible.

(a) Access. Seller (i) shall give to Buyer and to its representatives (such representatives to include employees, consultants, independent contractors, attorneys and other advisors of Buyer) full access to all of the Properties and the Records, as well as all of the offices, personnel, books, files, records, contracts, correspondence, computer output and data files (to the extent Seller has the right to make same available), maps, data,

With respect to computerized materials which are owned by Seller, over which Seller has control or to which Seller has access, Seller shall make available such materials to Buyer to the extent it is not prohibited from so doing by existing contractual commitments and will use its reasonable best efforts to make available to Buyer after the Closing the use of any computer services which Buyer reasonably desires to utilize in the ownership or operation of the Properties.

(b) Cost and Expense Data. Seller shall provide Buyer, as soon as practicable after the date hereof and on a continuing basis, all pertinent cost, expense and revenue data with respect to the Properties attributable to all periods through the Effective Time as the same becomes available.

Prior to Closing, Seller shall (i) cause the Leases and the Properties to be developed, maintained and operated in a manner substantially consistent with prior operations and applicable Law, (ii) not abandon any part of the Properties, (iii) not consent to or commence any operations on any one or more of the Leases or the Properties, except emergency operations, already-approved operations required under presently existing contractual obligations and on-going commitments, (iv) not convey, transfer, farmout, sell, encumber, remove, or otherwise dispose of any part of the Properties (other than Hydrocarbons produced from the Properties in the regular course of

business), (v) not reduce or terminate (or caused to be reduced or terminated) any insurance coverage now held in connection with the Properties, (vi) not enter into new contracts or oil and gas leases or otherwise obtain a leasehold interest covering the Lands without the prior written consent of Buyer, such consent not to be unreasonably withheld; provided, however, Seller may extend or renew existing Leases upon providing Buyer written notice of the same, (vii) waive any right of material value relating to the Properties, (viii) modify or terminate any of the Contracts, (ix) incur any other costs or expenses in connection with the Properties for which Buyer will be responsible if Closing occurs which individually exceeds $25,000.00 or in the aggregate exceeds $100,000.00, (x) materially alter any of the Properties, or (xi) take any other actions with respect to the Properties outside of the ordinary course of business, consistent with Seller’s past practices.

(d) Notification of Certain Events.

(e) Other Documents. At the Closing, Seller will execute and deliver to Buyer all other documents in addition to the Assignment as may be reasonably requested by Buyer to effectuate the transactions contemplated by this Agreement.

7.2 Preferential Rights. Prior to the Closing, Seller shall use commercially reasonable efforts to comply with all preferential rights to purchase or similar rights relative to the sale of any of the Properties as set forth in Schedule 4.1(x) (the “Preferential Rights”). Seller shall not be required to provide consideration or undertake obligations to or for the benefit of the holders of the Preferential Rights (other than as set forth in the instrument creating the Preferential Right) in order to satisfy its obligations under this Section 7.2. In accordance with this Agreement and the applicable Contracts, promptly after the execution of this Agreement, Seller shall deliver by mail written notices of the proposed transfer of any Property subject to the Preferential Rights to the holders of such Preferential Rights. Seller shall promptly notify Buyer if any Preferential Right is exercised or if the requisite period has elapsed without said right having been exercised. If a third party who has been offered an interest in any Property pursuant to a Preferential Right elects, prior to the Closing, to purchase such Property pursuant to the aforesaid offer, then the Property or part thereof so affected will be eliminated from the Properties, the Purchase Price will be reduced by the portion of the Allocated Value attributable to such Property that is affected by such Preferential Right, and subject to the other terms of this Agreement, the Parties shall proceed to Closing; provided, however, if any such Purchase Price reduction equals or exceeds $1,000,000.00, then Buyer shall have the right to terminate this Agreement. Otherwise, the Properties shall be conveyed to Buyer at Closing subject to any Preferential Right that has not been waived; provided, however, if (i) the holders of one or more of the Preferential Rights have not either waived or exercised such Preferential Rights because the time periods to exercise such Preferential Rights have not expired as of the time scheduled

for Closing hereunder and (ii) the total of the Allocated Values of the Properties subject to such Preferential Rights exceeds $1,000,000.00, then Buyer shall have the right to delay the Closing until such time periods have expired. If a third party elects to purchase any Property pursuant to a Preferential Right after the Closing Date, Buyer shall be obligated to convey such Property to such third party and shall be entitled to the consideration for the sale of such Property.

7.3 Consents to Assignment. Prior to Closing, Seller shall use commercially reasonable efforts to obtain all consents set forth in Schedule 4.1(x). Seller shall not be required to provide consideration or undertake obligations to or for the benefit of the holders of such consents other than as set forth in the instrument creating such consent right. Promptly after execution of this Agreement, Seller shall deliver by mail written requests for such consents to the holders thereof. If Seller fails to obtain a consent prior to the Closing, and either (a) the failure to obtain such consent would cause the assignment of such Property to Buyer to be void, and the value of the affected Property is in excess of $10,000.00 or it would require an expenditure in excess of $10,000.00 to remedy the failure to obtain such consent, or (b) the failure to obtain such consent could reasonably be expected to cause Buyer to incur damages and/or costs and expenses in connection therewith in excess of $10,000.00, then, at the option of Buyer, (i) the portion of the Property subject to such failed consent shall constitute a Title Defect and Seller and Buyer shall have the rights and remedies set forth herein with respect thereto; provided, however, the Defect Deductible shall not apply to such remedies for such failed consent, or (ii) such portion of the Properties subject to such failed consent shall be retained by Seller for the benefit of Buyer; provided that when such third party consent has been received, Seller acknowledges and agrees to transfer such portion of the Properties to Buyer; provided further that in the event Seller shall be unable to obtain such third party consent, Seller shall nevertheless retain the affected interest in trust for the Buyer and transfer to Buyer all economic benefits attributable to the interest as of and after the Effective Time.

Seller shall prepare an initial draft of the Post-Closing Settlement Statement and

submit same to Buyer no later than ninety (90) days after the Closing Date for Buyer’s comments and preliminary approval, which comments and/or approval shall be provided to Seller no later than fifteen (15) days after the receipt from Seller of the initial draft of the Post-Closing Settlement Statement. The Parties shall undertake to attempt to agree with respect to the amounts due pursuant to such Post-Closing Settlement Statement by no later than fifteen (15) days after the date of Seller’s receipt of Buyer’s comments, and Buyer or Seller, as the case may be, shall promptly pay to the other such sums as may be found to be due in said Post-Closing Settlement Statement as agreed upon by the Parties. During the foregoing periods of time, either Party may at its own expense audit the other Party’s books, accounts and records relating to Net Operating Income and any other item in the Post-Closing Settlement Statement. Such audit shall be conducted so as to cause a minimum of inconvenience to the audited Party. The occurrence of the Closing shall not relieve either Party of its obligation to account to the other Party after the Closing with respect to amounts that are received or become due after the Closing and that are properly payable or chargeable to either Party pursuant to any provision of this Agreement.

(b) If Seller and Buyer are unable to agree with respect to the amounts due pursuant to such Post-Closing Settlement Statement within thirty (30) days after the receipt from Seller of the initial draft of the Post-Closing Settlement Statement, then, each of Buyer and Seller shall, within five (5) Business Days after such time period, summarize its position with regard to such dispute in a written document of twenty pages or less and submit such summaries to a mutually agreeable accounting firm selected by the Parties (the “Accounting Arbitrator”), together with the Post-Closing Settlement Statement and any other documentation such Party may desire to submit. Within ten (10) Business Days after receiving the Parties’ respective submissions, the Accounting Arbitrator shall render a decision with respect to each matter addressed in such summaries, based on the materials described above. Any decision rendered by the Accounting Arbitrator pursuant hereto shall be final, conclusive and binding on Seller and Buyer and will be enforceable against the Parties in any court of competent jurisdiction. The costs of such Accounting Arbitrator shall be borne one-half by Buyer and one-half by Seller.

10.2 Ad Valorem Taxes. Ad valorem taxes attributable to the Properties shall be allocated between Seller and Buyer as of the Effective Time.

10.3 Suspense Accounts. At Closing, by adjustment to the Purchase Price, Seller shall transfer to Buyer all funds held by Seller in suspense related to proceeds of production and attributable to third parties’ interests in the Properties or Hydrocarbon production from the Properties, funds suspended awaiting minimum disbursement requirements, funds suspended under division orders and funds suspended for title and other defects, including those funds listed

in Schedule 10.3. Buyer agrees to administer all such accounts and assume all payment obligations relating to such funds in accordance with all applicable Laws.

10.4 Imbalances. Effective as of the Closing, Buyer shall succeed to and assume the position of Seller with respect to all Imbalances relating to the Properties as set forth on Schedule 4.1(v), and as a result, (a) Buyer shall be entitled to receive any and all benefits and shall bear any and all burdens of such Imbalances and (b) Seller shall have no further rights or obligations with respect to such Imbalances. As part of the Closing Settlement Statement, an adjustment shall be made to take into account any Imbalances as of the Effective Time. In the event Seller is in a net overproduced position as of the Effective Time, the Purchase Price will be adjusted downward by an amount equal to the net overproduced quantity multiplied by the average gas price received by Seller for gas sold from the portion of the Properties in the county where the imbalance Property is located during the month immediately preceding the Effective Time (net of all allowable taxes and deductions) on an MMBtu basis. In the event Seller is in a net underproduced position as of the Effective Time, the Purchase Price shall be increased by an amount equal to the net underproduced quantity multiplied by the average price received by Seller for gas sold from the portion of the Properties in the county where the imbalance Property is located during the month immediately preceding the Effective Time (net of all allowable taxes and deductions) on an MMBtu basis.

10.5 Further Assurances. After the Closing Date, each Party at the request of the other and without additional consideration, shall execute and deliver, or shall cause to be executed and delivered, from time to time, such additional and further instruments of conveyance and transfer, and shall take such other actions as the other Party may require to convey and deliver the Properties to Buyer, to perfect Buyer’s title thereto, and to accomplish orderly transfer of the Properties to Buyer in a manner contemplated by this Agreement. After the Closing, the Parties further agree to cooperate to have all proceeds received attributable to the Properties to be paid to the proper Party hereunder and to have all expenditures to be made with respect to the Properties to be made by the proper Party hereunder, all giving effect to the intents and purposes of this Agreement.

ARTICLE XI

TERMINATION

11.1 Right of Termination. This Agreement and the transactions contemplated by this Agreement may be completely terminated at any time at or prior to the Closing:

(a) by mutual consent of the Parties;

(b) by either Party if the Closing shall not have occurred on or before September 30, 2011; provided, however, that neither Party can terminate this Agreement if such Party is in material breach of this Agreement;

(c) by Seller, at Seller’s option, in the event the conditions set forth in Section 8.1 are not satisfied to the satisfaction of Seller at Closing;

(d) by Buyer, at Buyer’s option, if the conditions set forth in Section 8.2 are not satisfied to the satisfaction of Buyer at Closing;

(e) by either Party (i) pursuant to the last sentence of Section 5.4 (relating to Title Defects), Section 6.4 (relating to Environmental Defects) or Section 12.11 (relating to Casualty Loss), or (ii) if any court or Governmental Authority shall have issued an order, judgment or decree or taken any other action challenging, delaying, restraining, enjoining, prohibiting or invalidating the consummation of any of the transactions contemplated;

(f) by Buyer pursuant to Section 7.2 (relating to Preferential Rights); or

(g) by either Party if the sum of all Title Defect Amounts, Environmental Defect Amounts and the reduction of the Purchase Price pursuant to Section 7.2 and Section 12.11 exceeds 10% of the Purchase Price.

11.2 Effect of Termination. In the event that the Closing does not occur as a result of either Party exercising its right not to close pursuant to Section 11.1, then, except as provided in Section 3.2 and except for the provisions of Article I, this Section 11.2, and Article XII, this Agreement shall be null and void and neither Party shall have any rights or obligations under this Agreement, except that nothing shall relieve any Party from Liability for any willful breach of its covenants or agreements; provided that retention of the Deposit, together with any interest earned thereon, by Seller pursuant to Section 3.2(b) shall be Seller’s sole and exclusive remedy, shall serve as liquidated damages, and such retention of the Deposit shall constitute full and complete satisfaction of any and all damages Seller may have against Buyer, and all other rights, remedies and damages are hereby waived by Seller. NOTWITHSTANDING ANYTHING TO THE CONTRARY IN THIS AGREEMENT, IN NO EVENT SHALL EITHER PARTY BE ENTITLED TO RECEIVE ANY INDIRECT, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES, OR DAMAGES FOR LOST PROFITS OF ANY KIND OR LOSS OF BUSINESS OPPORTUNITY IN CONNECTION WITH THE TERMINATION OR BREACH OF THIS AGREEMENT.

FORM OF NON-FOREIGN STATUS AFFIDAVIT

[NOTE: TO BE REPLICATED FOR OTHER SELLER ENTITIES]

NON-FOREIGN STATUS AFFIDAVIT

Section 1445 of the Internal Revenue Code of 1986, as amended (the “Code”) provides that a transferee of a U.S. real property interest must withhold tax if the transferor is a foreign person. For U.S. tax purposes (including Section 1445 of the Code), the owner of a disregarded entity (which has legal title to a U.S. real property interest under local law) will be the transferor of the property and not the disregarded entity. To inform ENERGEN RESOURCES CORPORATION, an Alabama corporation (“Transferee”), whose mailing address is 605 Xxxxxxx Xxxxxxxxx Xx. Blvd. North, Birmingham, Alabama 35203-2707, that withholding of tax is not required upon the disposition of a U.S. real property interest by REEF GLOBAL ENERGY VII, L.P., a Nevada limited partnership (“Transferor”), the undersigned hereby certifies as follows:

1. Transferor is not a foreign corporation, foreign partnership, foreign trust or foreign estate (as those terms are defined in the Code and the regulations promulgated thereunder);

2. Transferor is not a disregarded entity as defined in Treasury Regulations section 1.1445-2(b)(2)(iii);

3 Transferor’s U.S. employer identification number is [ - ]; and

4. Transferor’s office address is 0000 Xxxxx Xxxxxxx Xxxxxxxxxx, Xxxxx 000, Xxxxxxxxxx, Xxxxx 00000.

Transferor understands that this certification may be disclosed to the Internal Revenue Service by Transferee and that any false statement contained herein could be punished by fine, imprisonment, or both.

Under penalties of perjury, I declare that I have examined this certificate and, to the best of my knowledge and belief, it is true, correct, and complete, and I further declare that I have authority to sign this document on behalf of Transferor.
