Ladies and Gentlemen:

     Parallel Petroleum Corporation, a Delaware corporation (the “Company”), (as hereinafter defined) hereby agrees with you as follows:

          1. Issuance of Notes. Subject to the terms and conditions herein contained, the Company proposes to issue and sell to the initial purchasers listed on Schedule I hereto (the “Initial Purchasers”) for whom you are acting as representatives, $150,000,000 aggregate principal amount of 10 1/4% Senior Notes due 2014 (each a “Note” and, collectively, the “Notes”). The Notes will be issued pursuant to an indenture (the “Indenture”), to be dated as of July 31, 2007, by and between the Company and Wells Fargo Bank, National Association, as trustee (the “Trustee”). Capitalized terms used, but not defined herein, shall have the meanings set forth in the “Description of the Notes” section of the Final Offering Circular (as hereinafter defined).

     The Notes will be offered and sold to the Initial Purchasers pursuant to an exemption from the registration requirements under the Securities Act of 1933, as amended (the “Securities Act”). Upon original issuance thereof, and until such time as the same is no longer required under the applicable requirements of the Securities Act, the Notes shall bear the legends set forth in the final offering circular, dated the date hereof (the “Final Offering Circular”). The Company has prepared (i) a preliminary offering circular, dated July 17, 2007 (the “Preliminary Offering Circular”), (ii) a pricing term sheet attached hereto as Schedule II, which includes pricing terms and other information with respect to the Notes (the “Pricing Supplement”) and (iii) the Final Offering Circular relating to the offer and sale of the Notes (the “Offering”). “Offering Circular” means, as of any date or time referred to in this Agreement, the most recent offering circular

(whether the Time of Sale Document (as hereinafter defined) or the Final Offering Circular, and any amendment or supplement to either such document), including exhibits and schedules thereto. The time when sales of Securities are first made or confirmed by the Initial Purchasers to buyers is 1:16 p.m., Eastern time, on the date hereof, which is referred to hereinafter as the “Time of Sale,” and the Preliminary Offering Circular and the Pricing Supplement are collectively referred to herein as the “Time of Sale Document.”

          2. Terms of Offering. Each Initial Purchaser has advised the Company, and the Company understands, that such Initial Purchaser will make offers to sell (the “Exempt Resales”) some or all of the Notes purchased by such Initial Purchaser hereunder on the terms that will be set forth in the Final Offering Circular, as amended or supplemented, to persons (the “Subsequent Purchasers”) whom such Initial Purchaser (i) reasonably believes to be “qualified institutional buyers” as defined in Rule 144A under the Securities Act, as such may be amended from time to time (“QIBs”), (ii) reasonably believes (based upon written representations made by such persons to such Initial Purchaser) to be institutional “accredited investors” as defined in Rule 501(a)(1), (2), (3) or (7) under the Securities Act (“Accredited Investors”) or (iii) reasonably believes to be non-U.S. persons in reliance upon Regulation S under the Securities Act.

          Holders of the Notes (including Subsequent Purchasers) will have the registration rights set forth in the registration rights agreement applicable to the Notes (the “Registration Rights Agreement”), to be executed on and dated as of the Closing Date. Pursuant to the Registration Rights Agreement, the Company will agree, among other things, to file with the Securities and Exchange Commission (the “SEC”) (a) a registration statement under the Securities Act relating to the Notes (the “Exchange Notes”), which shall be identical in all material respects to the Notes (except that the Exchange Notes shall have been registered pursuant to such registration statement and will not be subject to restrictions on transfer or contain additional interest provisions) to be offered in exchange for the Notes (such offer to exchange being referred to as the “Exchange Offer”), and/or (b) under certain circumstances, a shelf registration statement pursuant to Rule 415 under the Securities Act (the “Shelf Registration Statement”) relating to the resale by certain holders of the Notes. If required under the Registration Rights Agreement, the Company will issue Exchange Notes to the Initial Purchasers (the “Private Exchange Notes”). If the Company fails to satisfy its obligations under the Registration Rights Agreement, it will be required to pay additional interest to the holders of the Notes under certain circumstances.

          This Agreement, the Indenture, the Registration Rights Agreement, the Notes, the Exchange Notes and the Private Exchange Notes are collectively referred to herein as the “Documents.”

          3. Purchase, Sale and Delivery. On the basis of the representations, warranties, agreements and covenants herein contained and subject to the terms and conditions herein set forth, the Company agrees to issue and sell to the Initial Purchasers, and each Initial Purchaser agrees to purchase severally and not jointly from the Company, the Notes at a purchase price of 97.0% of the aggregate principal amount thereof, in the respective principal

have been offered or sold or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of the Company (not to be unreasonably withheld, delayed or conditioned), insofar as any such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon:

	(i)		any untrue statement or alleged untrue statement of a material fact contained in the Time of Sale Document or the Final Offering Circular, or any amendment or supplement thereto;
	(ii)		the omission or alleged omission to state, in the Time of Sale Document or the Final Offering Circular or any amendment or supplement thereto, a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; or
	(iii)		any breach by the Company of its representations, warranties and agreements set forth herein or breach of applicable law;

and, subject to the provisions hereof, will reimburse, as incurred, such Initial Purchaser, director, officer, employee and each such controlling person for any legal or other expenses incurred by such Initial Purchaser or such controlling person in connection with investigating, defending against or appearing as a third-party witness in connection with any such loss, claim, damage, liability or action in respect thereof; provided, however, the Company will not be liable in any such case to the extent (but only to the extent) that such loss, claim, damage or liability resulted from any untrue statement or alleged untrue statement or omission or alleged omission made in the Time of Sale Document or the Final Offering Circular or any amendment or supplement thereto in reliance upon and in conformity with written information concerning any Initial Purchaser furnished to the Company by such Initial Purchaser specifically for use therein. The indemnity agreement set forth in this Section 8 shall be in addition to any liability that the Company may otherwise have to the indemnified parties.

(b)

Each Initial Purchaser agrees to indemnify and hold harmless each of the Company, its directors, officers and employees and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act against any losses, claims, damages or liabilities of any kind to which the Company or any such director, officer, employee or controlling person may become subject under the Securities Act, the Exchange Act or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of the Initial Purchasers (not to be unreasonably withheld, delayed or conditioned), insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in the Time of Sale Document or the Final Offering Circular or any amendment or supplement thereto, (ii) the omission or the alleged omission to state a material fact in the Time of Sale Document or the Final Offering Circular or any amendment or supplement thereto necessary to make the

statements therein not misleading, in each case to the extent (but only to the extent) that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information concerning such Initial Purchaser, furnished to the Company or its agents by the Initial Purchaser specifically for use therein and (iii) any breach by the Initial Purchasers of their respective representations, warranties and agreements set forth herein or breach of applicable law; and, subject to the limitation set forth immediately preceding this clause, will reimburse, as incurred, any legal or other expenses incurred by the Company or any such director, officer, employee or controlling person in connection with any such loss, claim, damage, liability or action in respect thereof. This indemnity agreement will be in addition to any liability that the Initial Purchaser may otherwise have to the indemnified parties.

(c)

As promptly as reasonably practicable after receipt by an indemnified party under this Section 8 of notice of the commencement of any action for which such indemnified party is entitled to indemnification under this Section 8, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party of the commencement thereof in writing; but the omission to so notify the indemnifying party (i) will not relieve such indemnifying party from any liability under paragraph (a) or (b) above unless and only to the extent it is materially prejudiced as a result thereof and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraphs (a) and (b) above. In case any such action is brought against any indemnified party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may elect, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party; provided, however, that if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the defendants in any such action include both the indemnified party and the indemnifying party, and the indemnified party shall have concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be one or more legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party, or (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after receipt by the indemnifying party of notice of the institution of such action, then, in each such case, the indemnifying party shall not have the right to direct the defense of such action on behalf of such indemnified party or parties and such indemnified party or parties shall have the right to select separate counsel to defend such action on behalf of such indemnified party or parties at the expense of the indemnifying party. After notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof and approval by such indemnified party of counsel appointed to defend such action, the indemnifying party will not be liable to such indemnified party under this Section 8 for any legal or other expenses, other than reasonable costs of investigation, subsequently

incurred by such indemnified party in connection with the defense thereof, unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the immediately preceding sentence (it being understood, however, that in connection with such action the indemnifying party shall not be liable for the expenses of more than one separate counsel (in addition to local counsel) in any one action or separate but substantially similar actions in the same jurisdiction arising out of the same general allegations or circumstances, designated by the Initial Purchaser in the case of paragraph (a) of this Section 8 or the Company in the case of paragraph (b) of this Section 8, representing the indemnified parties under such paragraph (a) or paragraph (b), as the case may be, who are parties to such action or actions), (ii) the indemnifying party has authorized in writing the employment of counsel for the indemnified party at the expense of the indemnifying party or (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action, in each of which cases the fees and expenses of counsel shall be at the expense of the indemnifying party and shall be paid as they are incurred. After such notice from the indemnifying party to such indemnified party, the indemnifying party will not be liable for the costs and expenses of any settlement of such action effected by such indemnified party without the prior written consent of the indemnifying party (which consent shall not be unreasonably withheld), unless such indemnified party waived in writing its rights under this Section 8, in which case the indemnified party may effect such a settlement without such consent.

(d)

No indemnifying party shall be liable under this Section 8 for any settlement of any claim or action (or threatened claim or action) effected without its written consent, which shall not be unreasonably withheld, but if a claim or action settled with its written consent, or if there be a final judgment for the plaintiff with respect to any such claim or action, each indemnifying party jointly and severally agrees, subject to the exceptions and limitations set forth above, to indemnify and hold harmless each indemnified party from and against any and all losses, claims, damages or liabilities (and legal and other expenses as set forth above) incurred by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party (which consent shall not be unreasonably withheld), effect any settlement or compromise of any pending or threatened proceeding in respect of which the indemnified party is or could have been a party, or indemnity could have been sought hereunder by the indemnified party, unless such settlement (A) includes an unconditional written release of the indemnified party, in form and substance satisfactory to the indemnified party, from all liability on claims that are the subject matter of such proceeding and (B) does not include any statement as to an admission of fault, culpability or failure to act by or on behalf of the indemnified party.

(e)

In circumstances in which the indemnity agreement provided for in the preceding paragraphs of this Section 8 is unavailable to, or insufficient to hold harmless, an indemnified party in respect of any losses, claims, damages or liabilities (or actions in respect thereof), each indemnifying party, in order to provide for just and equitable contributions, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in

such proportion as is appropriate to reflect (i) the relative benefits received by the indemnifying party or parties, on the one hand, and the indemnified party, on the other, from the Offering or (ii) if the allocation provided by the foregoing clause (i) is not permitted by applicable law, not only such relative benefits but also the relative fault of the indemnifying party or parties, on the one hand, and the indemnified party, on the other, in connection with the statements or omissions or alleged statements or omissions that resulted in such losses, claims, damages or liabilities (or actions in respect thereof). The relative benefits received by the Company, on the one hand, and the Initial Purchasers, on the other, shall be deemed to be in the same proportion as the total proceeds from the Offering (before deducting expenses) received by the Company bear to the total discounts and commissions received by the Initial Purchasers. The relative fault of the parties shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company, on the one hand, or the Initial Purchasers, on the other, the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission or alleged statement or omissions, and any other equitable considerations appropriate in the circumstances.

(f)

The Company and the Initial Purchasers agree that it would not be equitable if the amount of such contribution determined pursuant to the immediately preceding paragraph (e) were determined by pro rata or per capita allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the first sentence of the immediately preceding paragraph (e). Notwithstanding any other provision of this Section 8, each Initial Purchaser shall not be obligated to make contributions hereunder that in the aggregate exceed the total discounts, commissions and other compensation received by such Initial Purchaser under this Agreement, less the aggregate amount of any damages that such Initial Purchaser has otherwise been required to pay by reason of the untrue or alleged untrue statements or the omissions or alleged omissions to state a material fact. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of the immediately preceding paragraph (e), each person, if any, who controls an Initial Purchaser within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as such Initial Purchaser, and each director of the Company, each officer of the Company and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, shall have the same rights to contribution as the Company.

          9. Termination. The Initial Purchasers may terminate this Agreement at any time prior to the Closing Date by written notice to the Company if any of the following has occurred:

(a)

since the date hereof, any Material Adverse Effect or development involving or expected to result in a prospective Material Adverse Effect that could, in the Initial Purchasers’ judgment, be expected to (i) make it impracticable or inadvisable to proceed with the offering or delivery of the Notes on the terms and in the manner contemplated in the Time of Sale Document and the Final Offering Circular, or (ii) materially impair the investment quality of any of the Notes;

(b)

the failure of the Company to satisfy the conditions contained in Section 7(a) hereof on or prior to the Closing Date;

(c)

any outbreak or escalation of hostilities or other national or international calamity or crisis, including acts of terrorism, or material adverse change or disruption in economic conditions in, or in the financial markets of, the United States (it being understood that any such change or disruption shall be relative to such conditions and markets as in effect on the date hereof), if the effect of such outbreak, escalation, calamity, crisis, act or material adverse change in the economic conditions in, or in the financial markets of, the United States could be reasonably expected to make it, in the Initial Purchaser’s judgment, impracticable or inadvisable to market or proceed with the offering or delivery of the Notes on the terms and in the manner contemplated in the Time of Sale Document and the Final Offering Circular or to enforce contracts for the sale of any of the Notes;

(d)

trading in the Company’s common stock shall have been suspended by the SEC or the NASDAQ Global Market or the suspension or limitation of trading generally in securities on the New York Stock Exchange, the American Stock Exchange or the NASDAQ Global Market or any setting of limitations on prices for securities on any such exchange or NASDAQ Global Market;

(e)

the enactment, publication, decree or other promulgation after the date hereof of any Applicable Law that in the Initial Purchaser’s counsel’s reasonable opinion materially and adversely affects, or could be reasonably expected to materially and adversely affect, the properties, business, prospects, operations, earnings, assets, liabilities or condition (financial or otherwise) of the Company;

(f)

any securities of the Company shall have been downgraded or placed on any “watch list” for possible downgrading by any “nationally recognized statistical rating organization,” as such term is defined for purposes of Rule 436(g)(2) under the Securities Act; or

(g)

the declaration of a banking moratorium by any Governmental Authority; or the taking of any action by any Governmental Authority after the date hereof in respect of its monetary or fiscal affairs that in the Initial Purchaser’s opinion could reasonably be expected to have a material adverse effect on the financial markets in the United States or elsewhere.

          10. Survival of Representations and Indemnities. The representations and warranties, covenants, indemnities and contribution and expense reimbursement provisions and other agreements, representations and warranties of the Company set forth in or made pursuant

- 25 -

to this Agreement shall remain operative and in full force and effect, and will survive, regardless of (i) any investigation, or statement as to the results thereof, made by or on behalf of the Initial Purchasers, (ii) acceptance of the Notes, and payment for them hereunder, and (iii) any termination of this Agreement.

          11. Default by the Initial Purchaser. If, on the Closing Date any one or more of the Initial Purchasers shall fail or refuse to purchase Notes which it or they have agreed to purchase hereunder on such date, and the aggregate principal amount of the Notes which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase is not more than one tenth of the aggregate principal amount of the Notes to be purchased on such date, the other Initial Purchasers shall be obligated severally in the proportions that the principal amount of Notes set forth opposite their respective names in Schedule I (in the column titled “Total”) bears to the aggregate principal amount of Notes set forth opposite the names of all such non defaulting Initial Purchasers (in the column titled “Total”), or in such other proportions as the Initial Purchasers may specify, to purchase the Notes which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase on such date; provided that in no event shall the principal amount of Notes that any Initial Purchaser has agreed to purchase pursuant to Section 3 be increased pursuant to this Section 11 by an amount in excess of one tenth of such principal amount of Notes without the written consent of such Initial Purchaser. If, on the Closing Date any Initial Purchaser or Initial Purchasers shall fail or refuse to purchase Notes which it or they have agreed to purchase hereunder on such date, and the aggregate principal amount of Notes with respect to which such default occurs is more than one tenth of the aggregate principal amount of Notes to be purchased on such date, and arrangements satisfactory to the Initial Purchasers and the Company for the purchase of such Notes are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non defaulting Initial Purchaser or the Company. In any such case either the Initial Purchasers or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Final Offering Circular or in any other documents or arrangements may be effected. Any action taken under this paragraph shall not relieve any defaulting Initial Purchaser from liability in respect of any default of such Initial Purchaser under this Agreement.

          12. Information Supplied by the Initial Purchasers. The statements set forth on the cover page with respect to price and in the [first sentence of the third paragraph, the first and second sentences of the sixth paragraph and the seventh paragraph under the heading “Plan of Distribution”] in the Time of Sale Document and the Final Offering Circular (to the extent such statements relate to the Initial Purchasers) constitute the only information furnished by the Initial Purchasers to the Company for the purposes of Sections 4(a) and 8 hereof.

          13. No Fiduciary Relationship. The Company hereby acknowledges that the Initial Purchasers are acting solely as initial purchasers in connection with the purchase and sale of the Notes. The Company further acknowledges that the Initial Purchasers are acting pursuant to a contractual relationship created solely by this Agreement entered into on an arm’s length basis, and in no event do the parties intend that the Initial Purchasers act or be responsible as a fiduciary to the Company or its management, stockholders or creditors or any other person in

- 26 -

connection with any activity that the Initial Purchasers may undertake or have undertaken in furtherance of the purchase and sale of the Notes, either before or after the date hereof. The Initial Purchasers hereby expressly disclaim any fiduciary or similar obligations to the Company, either in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions, and the Company hereby confirms its understanding and agreement to that effect. The Company and the Initial Purchasers agree that they are each responsible for making their own independent judgments with respect to any such transactions and that any opinions or views expressed by the Initial Purchasers to the Company regarding such transactions, including, but not limited to, any opinions or views with respect to the price or market for the Notes, do not constitute advice or recommendations to the Company. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that either of the Company may have against the Initial Purchasers with respect to any breach or alleged breach of any fiduciary or similar duty to the Company in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions.

It is hereby stipulated and declared to be the intention of the parties that they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable.

EXHIBIT A

FORM OF OPINIONS OF
COMPANY COUNSEL

[Opinions to be delivered by Haynes and Boone, LLP]

     1. The Company is validly existing as a corporation in good standing under the laws of the State of Delaware.

     2. The Company is qualified as a foreign corporation for the transaction of business and is in good standing in the States of Texas and New Mexico, and we have no knowledge that the character of the business conducted by the Company or the location of the properties owned, leased or operated by it makes such qualification necessary in any other jurisdiction (except where the failure to so qualify would not, individually or in the aggregate, have a material adverse effect on the condition (financial or other), results of operations, business or prospects of the Company).

     3. The Company has all corporate power and authority to own and lease its properties and to conduct its business, as described in the Time of Sale Document and Final Offering Circular and to execute, deliver and perform its obligations under the Purchase Agreement, the Registration Rights Agreement and the Indenture.

     4. The Indenture has been duly authorized, executed and delivered by the Company and, assuming due execution and delivery thereof by the Trustee, constitutes a valid and legally binding agreement of the Company enforceable against the Company in accordance with its terms; and the Indenture conforms in all material respects with the requirements of the Trust Indenture Act and the rules and regulations of the Commission applicable to an indenture that is qualified thereunder.

     5. The Notes have been duly authorized, executed and delivered by the Company and, when duly authenticated as provided in the Indenture and paid for as provided in the Purchase Agreement, will be duly and validly issued and outstanding, will constitute valid and legally binding obligations of the Company enforceable against the Company in accordance with their terms and will be entitled to the benefits of the Indenture.

     6. The Exchange Notes and the Private Exchange Notes have been duly authorized by the Company and, when duly executed, authenticated, issued and delivered as contemplated by the Registration Rights Agreement, will be duly and validly issued and outstanding, will constitute valid and legally binding obligations of the Company enforceable against the Company in accordance with their terms and will be entitled to the benefits of the Indenture.

     7. The Purchase Agreement has been duly and validly executed and delivered by the Company.

     8. The Registration Rights Agreement has been duly authorized, executed and delivered by the Company and, when duly executed by the other parties thereto, will constitute a

valid and legally binding agreement of the Company enforceable against the Company in accordance with its terms.

     9. The Notes and the Indenture conform in all material respects to the description thereof contained under the heading “Description of the Notes” in the Time of Sale Document and in the Final Offering Circular. The statements set forth in the Time of Sale Document and the Final Offering Circular under the caption “Certain Federal Income Tax Considerations,” insofar as such statements purport to address the federal income tax laws of the United States, are accurate in all material respects.

     10. The Company is not, and after giving effect to the offering and sale of the Notes and the application of the proceeds thereof as described in the Time of Sale Document and in the Final Offering Circular will not be, an “investment company” within the meaning of the Investment Company Act.

     11. It is not necessary, in connection with the issuance and sale of the Notes to the Initial Purchasers and the initial resale of the Notes by the Initial Purchasers in the manner contemplated by the Purchase Agreement and the Final Offering Circular, to register the Notes under the Securities Act or prior to the commencement of the Exchange Offer or the effectiveness of the Shelf Registration Statement, to qualify the Indenture under the Trust Indenture Act.

     12. No consent, approval, authorization or order of any governmental or regulatory authority is required for the issuance and sale of the Notes to the Initial Purchasers or the consummation by the Company of the transactions contemplated by the Purchase Agreement, the Registration Rights Agreement or the Indenture, except for such consents, approvals, authorizations, registrations or qualifications as may be required under state securities or Blue Sky laws, and with respect to the transactions contemplated by the Registration Rights Agreement, as may be required under the Securities Act or the Trust Indenture Act.

Other Matters

     We have participated in conferences with officers of the Company, representatives of the independent certified public accountants of the Company, and representatives of the Initial Purchasers and their counsel, at which conferences the contents of the Time of Sale Document and the Final Offering Circular and related matters were discussed and, although we have not independently verified and are not passing upon and assume no responsibility for the accuracy, completeness or fairness of the statements contained in the Time of Sale Document and the Final Offering Circular, on the basis of the foregoing, no facts have come to our attention that have led us to believe that the Time of Sale Document, as of the Time of Sale or the Closing Date, or the Final Offering Circular, as of its date or the Closing Date, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary to make the statements contained therein, in the light of the circumstances under which they were made, not misleading (it being understood that we express no view with respect to the financial statements and related schedules included therein, including the notes and the auditor’s report thereon and the other information and data of a financial or accounting nature and oil and gas reserve evaluation data and related data included in the Time of Sale Document and the Final Offering Circular).

[Opinions to be delivered by Lynch, Chappell & Alsup, P.C.]

[Reserved]

     1. The Company is not in violation of its articles of incorporation, bylaws, partnership or limited liability company agreement or other organizational document.

     2. The execution, delivery or performance by the Company of the Purchase Agreement, the Registration Rights Agreement or the Indenture nor the consummation of any of the transactions contemplated therein constitutes or will constitute, whether with or without the giving of notice or lapse of time or both, a breach of, or default under or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company pursuant to any contract, indenture, mortgage, deed of trust, loan or credit agreement, note, lease or any other agreement or instrument to which the Company is a party or by which it may be bound, or to which any of the property or assets of the Company is subject (except for such breaches or defaults or liens, charges or encumbrances that would not result in a Material Adverse Effect), nor will any such action result in any violation of (a) the provisions of the charter or bylaws or similar documents of the Company, (b) any applicable laws (assuming compliance with all applicable securities laws) or (c) any judgment, order, writ or decree of any court, governmental agency or arbitrator that is known to us to be applicable to the Company or any of its properties, which in the case of clause (b) and (c) would not cause a Material Adverse Effect.

Other Matters

     We have participated in conferences with officers of the Company, representatives of the independent certified public accountants of the Company, and representatives of the Initial Purchasers and their counsel, at which conferences the contents of the Time of Sale Document and the Final Offering Circular and related matters were discussed and, although we have not independently verified and are not passing upon and assume no responsibility for the accuracy, completeness or fairness of the statements contained in the Time of Sale Document and the Final Offering Circular, on the basis of the foregoing, no facts have come to our attention that have led us to believe that the Time of Sale Document, as of the Time of Sale or the Closing Date, or the Final Offering Circular, as of its date or the Closing Date, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary to make the statements contained therein, in the light of the circumstances under which they were made, not misleading (it being understood that we express no view with respect to the financial statements and related schedules included therein, including the notes and the auditor’s report thereon and the other information and data of a financial or accounting nature and oil and gas reserve evaluation data and related data included in the Time of Sale Document and the Final Offering Circular).
