The Firm Securities and the Option Securities (to the extent the aforementioned option is exercised) are herein collectively called the “Shares.”

     In consideration of the mutual agreements contained herein and of the interests of the parties in the transactions contemplated hereby, the parties hereto agree as follows:

1. Representations and Warranties of the Issuer.

     The Issuer represents and warrants to each of the Underwriters as follows:

     (a) The Registration Statement has been filed with the Commission under the Securities Act and has become effective under the Securities Act. The Issuer meets the requirements for use of Form S-3 under the Securities Act and has not been notified by the Commission of any objection to the use of the Registration Statement on Form S-3. No stop order suspending the effectiveness of the Registration Statement is in effect, and no proceedings for such purpose are pending before or, to the knowledge of the Issuer, threatened by the Commission. The Commission has not issued any order preventing or suspending the use of the Prospectus or any Issuer Free Writing Prospectus. Copies of the Registration Statement and each of the amendments thereto have been delivered by the Issuer to the Representative (provided that availability of the Registration Statement and each amendment on EDGAR shall constitute delivery so long as the EDGAR copy is substantially identical except as permitted by Regulation S-T). The Registration Statement conforms, and any further amendments or supplements to the Registration Statement will conform at the time they become effective or are filed with the Commission, in all material respects to the requirements of the Securities Act and the Rules and Regulations. The Prospectus, as of its date, will conform and, as it may be further supplemented by filings with the Commission, will conform, on the Closing Date (as defined below) and each Option Closing Date (as defined below), in all material respects to the requirements of the Securities Act and the Rules and Regulations. As of the Effective Date, the date hereof, the Closing Date (as defined below) and each Option Closing Date (as defined below), if any, the Registration Statement, and any post-effective amendments, do not and will not, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they are made, not misleading; the Prospectus, as of its date, will not, and, on the Closing Date and each Option Closing Date, as amended or supplemented by filings with the Commission, will not, contain an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; and the Disclosure Package, taken as a whole, as of the Applicable Time, did not contain an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they

were made, not misleading. Notwithstanding the foregoing, none of the representations and warranties set forth in this Section 1(a) shall apply to statements or omissions in the Registration Statement, or the Prospectus, or any amendment or supplement in reliance upon and in conformity with written information furnished to the Issuer by any Underwriter through RBC expressly for use therein, such information being listed in Section 13 below.

     (b) Other than the Registration Statement, the Prospectus and the Disclosure Package, the Issuer (including its agents and representatives, other than the Underwriters in their capacity as such) has not made, used, prepared, authorized, approved or referred to and will not prepare, make, use, authorize, approve or refer to any Issuer Free Writing Prospectus other than (i) any document not constituting a prospectus pursuant to Section 2(a)(10)(a) of the Securities Act or Rule 134 under the Securities Act or (ii) the documents listed on Schedule II hereto, any Issuer Free Writing Prospectus that constitutes a “road show” (within the meaning specified in Rule 433 of the Rules and Regulations) or any other written communications approved in writing in advance by the Representative. Each such Issuer Free Writing Prospectus complied in all material respects with the Securities Act, has been or will be (within the time period specified in Rule 433) filed in accordance with the Securities Act (to the extent required thereby) and, when taken together with the most recent Preliminary Prospectus, the other Issuer Free Writing Prospectuses identified on Schedule II and the information to be conveyed orally as set forth on Schedule III, such Issuer Free Writing Prospectus, did not, and, when taken together with the Prospectus, the other Issuer Free Writing Prospectuses identified on Schedule II and the information to be conveyed orally as set forth on Schedule III, at the Closing Date and as of the Option Closing Date, as the case may be, will not, contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, that the Issuer makes no representation and warranty with respect to any statements or omissions made in each such Issuer Free Writing Prospectus in reliance upon and in conformity with information relating to any Underwriter furnished to the Issuer in writing by such Underwriter through the Representative expressly for use in such Issuer Free Writing Prospectus, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in Section 13 hereof; provided, further, that the Issuer makes no representation and warranty with respect to any statements or omissions made in any Offering Participant Free Writing Prospectus, including any issuer information (as defined in Rule 433 under the Securities Act) therein. Each such Issuer Free Writing Prospectus, as of its issue date and at all subsequent times through the completion of the public offering and sale of the Shares did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained in the Registration Statement or the Prospectus, including any document incorporated by reference therein and any Preliminary Prospectus deemed to be a part thereof that has not been superseded or modified.

     (c) The documents incorporated by reference in the Registration Statement, the Preliminary Prospectus, the Prospectus and the Disclosure Package, at the time they became effective or were filed with the Commission, as the case may be, complied in all material respects with the requirements of the Securities Act or the Exchange Act, as applicable, and the

rules and regulations of the Commission thereunder, and none of such documents, when read together with the other information in the Disclosure Package, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, and any further documents so filed and incorporated by reference in the Registration Statement, the Prospectus and the Disclosure Package, when such documents become effective or are filed with the Commission, as the case may be, will conform in all material respects to the requirements of the Securities Act or the Exchange Act, as applicable, and the rules and regulations of the Commission thereunder and will not, when read together with the other information in the Disclosure Package, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they are made, not misleading.

     (d) (i) At the time of filing the Registration Statement and (ii) as of the Effective Date (with such date being used as the determination date for purposes of this clause (ii)), the Issuer was not and is not an “ineligible issuer” (as defined in Rule 405).

     (e) The financial statements of the Issuer (including all notes and schedules thereto) included or incorporated by reference in the Registration Statement, the Prospectus and the Disclosure Package present fairly in all material respects the financial position of the Issuer and its consolidated subsidiaries at the dates indicated and the statement of operations, shareholders’ equity and cash flows of the Issuer and its consolidated subsidiaries for the periods specified; and such financial statements and related schedules and notes thereto have been prepared in conformity with U.S. generally accepted accounting principles, consistently applied throughout the periods involved. The summary and selected financial data included in the Prospectus and the Disclosure Package present fairly in all material respects the information shown therein as at the respective dates and for the respective periods specified and have been presented on a basis consistent with the consolidated financial statements set forth in the Prospectus and the Disclosure Package and other financial information.

     (f) Murrell, Hall, McIntosh & Co., PLLP, which has certified certain financial statements of the Issuer and delivered its opinion with respect to the audited financial statements and schedules included or incorporated by reference in the Registration Statement and the Prospectus, is an independent registered public accounting firm with respect to the Issuer within the meaning of the Securities Act, the Exchange Act and the rules and regulations of the Commission thereunder.

     (g) The Issuer and each of the subsidiaries of the Issuer listed in Exhibit A hereto (other than Quest Pipelines (KPC), which is a general partnership), which list includes all “significant subsidiaries” as defined in Rule 405 of the Rules and Regulations (collectively, the “Subsidiaries”), is duly organized, validly existing and in good standing under the laws of their respective jurisdictions of incorporation, organization or formation, as the case may be. The Issuer and each of its Subsidiaries is duly qualified to do business and is in good standing as a foreign corporation, limited partnership or limited liability company in each jurisdiction in which the nature of the business conducted by it or location of the assets or properties owned, leased or licensed by it requires such qualification, except for such jurisdictions where the failure to so qualify individually or in the aggregate would not have a material adverse effect on the assets, properties, financial condition, results of operations, business affairs or business prospects of the Issuer and its Subsidiaries considered as a whole or materially impair the ability or likelihood of the transactions provided for in the Membership Interest Purchase Agreement by and between the Company and PetroEdge Resources Partners, LLC, a Delaware limited liability company, dated June 5, 2008 (the “PetroEdge Agreement”), to be consummated on or before July 11, 2008 in accordance with the terms thereof (each, a “Material Adverse Effect”); and to the Issuer’s knowledge, no proceeding has been instituted in any such jurisdiction revoking, limiting or curtailing, or seeking to revoke, limit or curtail, such power and authority or qualification. Other than the Subsidiaries and as disclosed in the Registration Statement, the Issuer does not own, directly or indirectly, any shares of capital stock and does not have any other equity or ownership or proprietary interest in any corporation, partnership, association, trust, limited liability company, joint venture or other entity.

     (h) The Issuer and each of its Subsidiaries has all requisite corporate, limited partnership, general partnership or limited liability company, as the case may be, power and authority, and all necessary authorizations, approvals, consents, orders, licenses, certificates and permits of and from all governmental or regulatory bodies or any other person or entity (collectively, the “Permits”), to own, lease and license its assets and properties and conduct its business, all of which are valid and in full force and effect, except where the lack of such Permits, individually or in the aggregate, would not have a Material Adverse Effect. The Issuer and each of its Subsidiaries has fulfilled and performed in all material respects all of its material obligations with respect to such Permits and no event has occurred that allows, or after notice or lapse of time would allow, revocation or termination thereof or results in any other material impairment of the rights of the Issuer or any of its Subsidiaries thereunder. Neither the Issuer nor any of its Subsidiaries has received notice of any reservation or modification of any such Permits, except as would not, individually or in the aggregate, have a Material Adverse Effect.

     (i) Except as disclosed in the Registration Statement, the Prospectus and the Disclosure Package, the Issuer and each of its Subsidiaries has, and following the consummation of the transactions contemplated by the PetroEdge Agreement will have, (i) defensible title to all its interests in the oil and gas properties described in the Registration Statement, the Prospectus and the Disclosure Package as being or to be owned or leased by them, title investigations having been carried out by the Issuer in accordance with customary practice in the oil and gas industry, and (ii) good and indefeasible title to all other real property and all personal property

described in the Registration Statement, the Prospectus and the Disclosure Package as being or to be owned by them, in each case free and clear of all Liens, except (A) such as would not have a Material Adverse Effect, (B) security interests securing loans under the Issuer’s or any of its Subsidiary’s credit facilities disclosed in the Registration Statement, Prospectus or Disclosure Package, (C) royalties, overriding royalties and other similar burdens under oil and gas leases, and (D) Liens under gas sales contracts, geophysical exploration agreements, operating agreements, farmout agreements, participation agreements, unitization, pooling and commutation agreements, declarations and orders and gas sales contracts, securing payment of amounts not yet due and payable and of a scope and nature customary in the oil and gas industry. All property held under lease by the Issuer and its Subsidiaries is held by them under valid, existing and enforceable leases, free and clear of all Liens, except such as would not have a Material Adverse Effect.

     (j) The Issuer and each of its Subsidiaries has, and following the consummation of the transactions contemplated by the PetroEdge Agreement will have, such easements or rights-of-way from each person (collectively, “rights-of-way”) as are necessary to conduct its business in the manner described, and subject to the limitations contained, in the Registration Statement, the Prospectus and the Disclosure Package, except for (i) qualifications, reservations and encumbrances as may be set forth in the Registration Statement, the Prospectus and the Disclosure Package and (ii) such rights-of-way that, if not obtained, would not have, individually or in the aggregate, a Material Adverse Effect; other than as set forth, and subject to the limitations contained, in the Registration Statement, the Prospectus and the Disclosure Package, the Issuer and each of its Subsidiaries has, and upon consummation of the transactions contemplated by the PetroEdge Agreement will have, fulfilled and performed all its material obligations with respect to such rights-of-way and no event has occurred that allows, or after notice or lapse of time would allow, revocation or termination thereof or would result in any impairment of the rights of the holder of any such rights-of-way, except for such revocations, terminations and impairments that would not have a Material Adverse Effect; and, except as described in the Registration Statement, the Prospectus and the Disclosure Package, none of such rights-of-way contains any restriction that is materially burdensome to the Issuer and its Subsidiaries, taken as a whole.

     (k) Except as described in the Registration Statement, the Prospectus and the Disclosure Package, there is (i) no action, suit or proceeding before or by any court, arbitrator or governmental agency, body or official, domestic or foreign, now pending or, to the knowledge of the Issuer, threatened, to which the Issuer or any of its Subsidiaries is or may be a party or to which the business or property of any of the Issuer or any of its Subsidiaries is or may be subject, (ii) no injunction, restraining order or order of any nature issued by a federal or state court or foreign court of competent jurisdiction to which the Issuer or any of its Subsidiaries is or may be subject, that, in the case of clauses (i) and (ii) above, is reasonably expected to (A) individually or in the aggregate have a Material Adverse Effect, (B) prevent or result in the suspension of the offer, issuance or sale of the Shares, or (C) call into question the validity of this Agreement or the PetroEdge Agreement.

     (l) Neither the Issuer nor any of its Subsidiaries has sustained, since the date of the latest audited financial statements included in the Registration Statement, the Prospectus and the Disclosure Package, any material loss or interference with its business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, investigation, order or decree, otherwise than as set forth or contemplated in the Registration Statement, the Prospectus and the Disclosure Package. Subsequent to the respective dates as of which information is given in the Registration Statement, the Prospectus and the Disclosure Package, in each case excluding any amendments or supplements to the foregoing made after the execution of this Agreement, there has not been (i) any Material Adverse Effect or any material adverse change, or any development involving, individually or in the aggregate, a prospective material adverse change, in the business, properties, management, financial condition, prospects, net worth or results of operations of the Issuer and its Subsidiaries taken as a whole, (ii) any transaction which is material to the Issuer and its Subsidiaries taken as a whole, (iii) any obligation or liability, direct or contingent (including any off-balance sheet obligations), incurred by the Issuer or any of its Subsidiaries, which is material to the Issuer and its Subsidiaries taken as a whole, (iv) any material change in the capitalization, ownership or outstanding indebtedness of the Issuer or any of its Subsidiaries, (v) any dividend or distribution of any kind declared, paid or made on the securities of the Issuer or any of its Subsidiaries, in each case whether or not arising from transactions in the ordinary course of business or (vi) any material adverse change, or any development involving, individually or in the aggregate, a prospective material adverse change, in the business, properties, management, financial condition, prospects, net worth or results of operations of the Issuer and its Subsidiaries taken as a whole that (A) would cause any statement included in the Registration Statement, the Disclosure Package or the Prospectus regarding the Issuer to be untrue in any material respect or (B) would be material to a stockholder of the Issuer that has not been disclosed in the Registration Statement, the Prospectus and the Disclosure Package.

     (m) There is no document, contract or other agreement required to be described in the Registration Statement, Prospectus or the Disclosure Package or to be filed as an exhibit to the Registration Statement which is not described or filed as required by the Securities Act or the Rules and Regulations.

     (n) Neither the Issuer nor any of its Subsidiaries is (i) in violation of its partnership agreement, limited liability company agreement, certificate of formation or conversion, certificate or articles of incorporation, bylaws or other constituent document, (ii) in violation of any law, statute, ordinance, administrative or governmental rule or regulation applicable to it or of any order, judgment, decree or injunction of any court or governmental agency or body having jurisdiction over the Issuer or any of its Subsidiaries or any of their properties or assets or (iii) in breach, default (or an event which, with notice or lapse of time or both, would constitute such a default) or violation in the performance of any obligation, agreement or condition contained in any bond, debenture, note or any other evidence of indebtedness or in any agreement, indenture, lease or other agreement or instrument to which it is a party or by which it or any of its properties may be bound, which breach, default or violation in the case of clause (ii) or (iii) would, if continued, have a Material Adverse Effect or materially impair the ability of the

Issuer to perform its obligations under this Agreement. To the knowledge of the Issuer, no third party to any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which the Issuer or any of its Subsidiaries is a party or by which any of them is bound or to which any of their properties is subject, is in breach, default or violation of any such agreement, which breach, default or violation would, if continued, have a Material Adverse Effect or materially impair the ability of the Issuer to perform its obligations under this Agreement.

     (o) Neither the execution, delivery and performance of this Agreement or the PetroEdge Agreement by the Issuer nor the consummation of any of the transactions contemplated hereby (including, without limitation, the issuance and sale by the Issuer of the Shares) and thereby will give rise to a right to terminate or accelerate the due date of any payment due under, or conflict with or result in the breach of any term or provision of, or constitute a default (or an event which with notice or lapse of time or both would constitute a default) under, or require any consent or waiver under, or result in the execution or imposition of any Lien upon any properties or assets of the Issuer or its Subsidiaries pursuant to the terms of, any indenture, mortgage, deed of trust or other agreement or instrument to which the Issuer or any of its Subsidiaries is a party or by which either the Issuer or its Subsidiaries or any of their properties or businesses is bound, or any franchise, license, permit, judgment, decree, order, law, statute, rule or regulation applicable to the Issuer or any of its Subsidiaries or violate any provision of the charter or bylaws of the Issuer or the charter or bylaws or similar organizational documents of any of its Subsidiaries, (i) except for such consents or waivers which have already been obtained and are in full force and effect, (ii) except for Liens being granted under the credit facilities disclosed in the Registration Statement, Prospectus or Disclosure Package, (iii) except for waivers and amendments to existing credit facilities to permit the consummation of the transactions contemplated by the PetroEdge Agreement and the related financings, (iv) except for such additional steps as may be necessary to qualify the Shares for public offering by the Underwriters under the state securities or blue sky laws, and (v) except as would not have a Material Adverse Effect.

     (pp) Neither the Issuer nor any of its Subsidiaries is a party to any contract, agreement or understanding with any person (other than this Agreement) that would give rise to a valid claim against the Issuer or any of its Subsidiaries or any Underwriter for a brokerage commission, finder’s fee or like payment in connection with the offering and sale of the Shares.

     (qq) Except as described in the Prospectus and the Disclosure Package or in the documents incorporated by reference into the Prospectus and the Disclosure Package, the Issuer has not sold or issued any shares of Common Stock during the six-month period preceding the date of the Prospectus, including any sales pursuant to Rule 144A under, or Regulations D or S of, the Securities Act, other than shares issued pursuant to employee benefit plans, qualified stock options plans or other employee compensation plans or pursuant to outstanding options, rights or warrants.

2. Purchase, Sale and Delivery of the Firm Securities.

     (a) On the basis of the representations, warranties and covenants herein contained, and subject to the conditions herein set forth, the Issuer agrees to sell to the Underwriters and each Underwriter agrees, severally and not jointly, to purchase, at a price of $9.69 per share, the number of Firm Securities set forth opposite the name of each Underwriter in Schedule I hereof, subject to adjustments in accordance with Section 9 hereof.

     (b) Payment for the Firm Securities to be sold hereunder is to be made by wire transfer of immediately available funds to the order of the Issuer against delivery of the Firm Securities in book-entry form to the Representative through the facilities of The Depository Trust Company, New York, New York for the several accounts of the Underwriters. Such payment and delivery are to be made at or prior to 9:00 a.m., Central Standard Time, on the third business day after the date of this Agreement or at such other time and date not later than five business days thereafter as the Representative and the Issuer shall agree upon, such time and date being herein referred to as the “Closing Date.” As used herein, “business day” means a day on which the New York Stock Exchange is open for trading and on which banks in New York are open for business and are not permitted by law or executive order to be closed. Electronic transfer of the Firm Securities shall be made to the Representative at the time of delivery in such names and in such denominations as the Representative shall specify to the Issuer. Deliveries of the documents described in Section 6 hereof with respect to the purchase of the Firm Securities shall be made at the offices of RBC, at or prior to 9:00 a.m., Central Standard Time, on the Closing Date.

     (c) In addition, on the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Issuer hereby grants an option to the several Underwriters to purchase the Option Securities at the price per share as set forth in the first paragraph of this Section. The option granted hereby may be exercised in whole or in part by giving written notice (i) at any time before the Closing Date and (ii) only once thereafter within 30 days after the date of this Agreement, by the Representative to the Issuer setting forth

the number of Option Securities as to which the several Underwriters are exercising the option, the names and denominations in which the Option Securities are to be registered and the time and date at which such certificates are to be delivered. The time and date at which certificates for Option Securities are to be delivered shall be determined by the Representative but shall not be earlier than three nor later than 10 full business days after the exercise of such option, nor in any event prior to the Closing Date (such time and date being herein referred to as the “Option Closing Date”). If the date of exercise of the option is three or more days before the Closing Date, the notice of exercise shall set the Closing Date as the Option Closing Date. The number of Option Securities to be purchased by each Underwriter shall be in the same proportion to the total number of Option Securities being purchased as the number of Firm Securities being purchased by such Underwriter bears to the total number of Firm Securities, adjusted by the Representative in such manner as to avoid fractional shares. The option with respect to the Option Securities granted hereunder may be exercised only to cover over-allotments in the sale of the Firm Securities by the Underwriters. The Representative may cancel such option at any time prior to its expiration by giving written notice of such cancellation to the Issuer. To the extent, if any, that the option is exercised, payment for and delivery of the Option Securities and delivery of the documents described in Section 6 hereof shall be made in the same manner as in the case of the Firm Securities.

3. Offering by the Underwriters.

     It is understood that the several Underwriters are to make a public offering of the Firm Securities as soon as the Representative deems it advisable to do so. The Firm Securities are to be offered to the public at the public offering price set forth in the Disclosure Package and the Prospectus Supplement. To the extent, if at all, that any Option Securities are purchased pursuant to Section 2 hereof, the Underwriters will offer them to the public on the foregoing terms.

     It is further understood that RBC will act as the Representative for the Underwriters in the offering and sale of the Shares in accordance with a Master Agreement Among Underwriters entered into by RBC and the several other Underwriters.

4. Covenants.

     (a) The Issuer covenants and agrees with the several Underwriters that it will (i) prepare and file the Prospectus Supplement with the Commission pursuant to Rule 424(b), (ii) not file any amendment to the Registration Statement or supplement to the Prospectus or any Issuer Free Writing Prospectus of which the Representative shall not previously have been advised and furnished with a copy or to which the Representative shall have reasonably objected in writing or which is not in compliance, in all material respects, with the Rules and Regulations; and (iii) file on a timely basis all reports and any definitive proxy or information statements required to be filed by the Issuer with the Commission subsequent to the date of the Prospectus and prior to the termination of the offering of the Shares by the Underwriters.

     (b) The Issuer has not distributed, and without the prior consent of the Representative it will not distribute, any prospectus or other offering material (including, without limitation, any offer relating to the Shares that would constitute a Free Writing Prospectus and content on the Issuer’s website that may be deemed to be a prospectus or other offering material) in connection with the offering and sale of the Shares, other than the materials referred to in Section 1(a). Each Underwriter represents and agrees that it has not made and, without the prior consent of the Issuer and the Representative, it will not make, any offer relating to the Securities that would constitute an Issuer Free Writing Prospectus, an Offering Participant Free Writing Prospectus or otherwise constitute a free writing prospectus as defined in Rule 405 under the Securities Act. Any such Issuer Free Writing Prospectus the use of which has been consented to by the Issuer and the Representative is listed on Schedule II hereto. The Issuer has complied and will comply with the requirements of Rule 433 under the Securities Act applicable to any Issuer Free Writing Prospectus, including timely filing with the Commission or retention where required and legending, and each Underwriter has complied and will comply with the requirements of Rule 433 under the Securities Act applicable to any Offering Participant Free Writing Prospectus, including timely filing with the Commission or retention where required and legending.

The Issuer agrees that if at any time following issuance of an Issuer Free Writing Prospectus any event occurred or occurs as a result of which such Issuer Free Writing Prospectus would conflict with the information in the Registration Statement or the Prospectus or would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, the Issuer will give prompt notice thereof to the Representative and, if requested by the Representative, will prepare and furnish without charge to each Underwriter an Issuer Free Writing Prospectus or other document which will correct such conflict, statement or omission; provided, however, that this covenant shall not apply to any statements or omissions in an Issuer Free Writing Prospectus made in reliance upon and in conformity with information furnished in writing to the Issuer by an Underwriter through the Representative expressly for use therein.

     (c) The Issuer will advise the Representative promptly (i) when any post-effective amendment to the Registration Statement shall have become effective; (ii) of receipt of any comments from the Commission; (iii) of any request of the Commission for amendment of the Registration Statement or for supplement to the Prospectus or for any additional information; and (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the use of the Prospectus or of the institution of any proceedings for that purpose. The Issuer will use its commercially reasonable efforts to prevent the issuance of any such stop order preventing or suspending the use of the Prospectus and to obtain as soon as possible the lifting thereof, if issued.

     (d) The Issuer will cooperate with the Representative in endeavoring to qualify the Shares for sale under the securities laws of such jurisdictions as the Representative may reasonably have designated in writing and will make such applications, file such documents, and

furnish such information as may be reasonably required for that purpose, provided the Issuer shall not be required to qualify as a foreign corporation or to file a general consent to service of process in any jurisdiction where it is not now so qualified or required to file such a consent or subject itself to taxation as doing business in any jurisdiction or qualify as a dealer of securities in any jurisdiction. The Issuer will, from time to time, prepare and file such statements, reports, and other documents, as are or may be required to continue such qualifications in effect for so long a period as the Representative may reasonably request for distribution of the Shares.

     (e) The Issuer will deliver to, or upon the order of, the Representative during the period when delivery of a Prospectus is required under the Securities Act, as many copies of the Prospectus in final form, or as thereafter amended or supplemented, as the Representative may reasonably request. The Issuer will deliver to the Representative at or before the Closing Date, signed copies of the Registration Statement and all amendments thereto including all exhibits filed therewith (provided that availability of the Registration Statement and each amendment on EDGAR shall constitute delivery so long as the EDGAR copy is substantially identical except as permitted by Regulation S-T).

     (f) The Issuer will comply with the Securities Act and the Rules and Regulations, and the Exchange Act, and the rules and regulations of the Commission thereunder, so as to permit the completion of the distribution of the Shares as contemplated in this Agreement and the Prospectus. If during the period in which a prospectus is required by law to be delivered by an Underwriter or dealer, any event shall occur as a result of which, in the judgment of the Issuer or in the reasonable opinion of the Underwriters, the Prospectus, as then amended or supplemented, would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or, if it is necessary at any time to amend or supplement the Prospectus to comply with the Securities Act or the Rules and Regulations, the Issuer promptly will prepare and file with the Commission an appropriate amendment to the Registration Statement or supplement to the Prospectus.

     (g) The Issuer will make generally available to its security holders and the Representative, as soon as it is practicable to do so, but in any event not later than the end of the fiscal quarter first occurring after the first anniversary of the date that the Prospectus Supplement is filed pursuant to Rule 424(b) under the Securities Act, an earning statement (which need not be audited) in reasonable detail, covering a period of at least 12 consecutive months beginning after the effective date of the Registration Statement, which earning statement shall satisfy the requirements of Section 11(a) of the Securities Act and Rule 158 of the Rules and Regulations.

     (h) The Issuer covenants and agrees that it will not offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, or file with the Commission a registration statement or amendment to a registration statement under the Securities Act relating to, any shares of its common stock or securities convertible into or exchangeable or exercisable for any shares of its common stock, or publicly disclose the intention to make any such offer, sale, pledge, disposition or filing for a period of 90 days after the date of this Agreement, directly or

indirectly, otherwise than hereunder or with the prior written consent of the Representative, provided, that this provision will not restrict the Issuer from (i) issuances pursuant to the exercise of options outstanding on the date hereof, (ii) grants of employee stock options and restricted stock and other securities issuances pursuant to the terms of a plan in effect on the date hereof, (iii) issuances pursuant to the exercise of such options, (iv) issuances to our employees under the terms of the employee stock purchase plan in effect on the date hereof, (v) issuances pursuant to our 401(k) plan, (vi) issuances to directors pursuant to the incentive plan in effect on the date hereof, (vii) the filing of registration statements on Form S-8 and amendments thereto in connection with those securities and plans, and (viii) the taking any of the foregoing actions in connection with the issuance of shares or other securities in connection with acquisitions and private placements by us.

     (i) The Issuer will use its reasonable best efforts to list, subject to notice of issuance, the Shares on The Nasdaq Global Market.

     (j) The Issuer shall apply the net proceeds of its sale of the Shares as described under the heading “Use of Proceeds” in the Prospectus and the Disclosure Package.

     (k) The Issuer shall not invest, or otherwise use the proceeds received by the Issuer from its sale of the Shares in such a manner as would require the Issuer or any of the Subsidiaries to register as an investment company under the 1940 Act.

     (l) The Issuer will maintain a transfer agent and, if necessary under the jurisdiction of incorporation of the Issuer, a registrar for the Common Stock.

     (m) The Issuer will not take, directly or indirectly, any action designed to or that could reasonably be expected to cause or result in stabilization or manipulation of the price of the Shares.

     (n) The Issuer will promptly (but in no event later than 24 hours) notify the Representative if it becomes aware of any fact or circumstance that might materially impair the ability or likelihood of the transactions provided for in the PetroEdge Agreement to be consummated on or before July 11, 2008 in accordance with the terms thereof. The Issuer shall not materially amend, modify, supplement or waive any provision of the PetroEdge Agreement without the prior written consent of the Representative, such consent not to be unreasonably withheld.

     If this Agreement is terminated by the Representative in accordance with the provisions of Section 11(a) (other than pursuant to Sections 6(h)(i), (iii), (iv) or (v)), the Issuer shall reimburse the Underwriters for all of their reasonable out-of-pocket expenses, including the reasonable fees and disbursements of counsel to the Underwriters.

6. Conditions of Obligations of the Underwriters.

     The obligations of the several Underwriters to purchase and pay for the Shares, as provided herein, shall be subject to the accuracy, as of the date hereof and as of the Closing Date (and, if applicable, each Option Closing Date), of the representations and warranties of the Issuer contained herein, to the performance by the Issuer of its covenants and obligations hereunder, and to the following additional conditions:

     (a) The Registration Statement and all post-effective amendments thereto shall have become effective not later than the Applicable Time. All filings required by Rule 424 and Rule 430B shall have been made. No stop order suspending the effectiveness of the Registration Statement shall have been issued and no proceeding for that purpose shall have been initiated or, to the knowledge of the Issuer or any Underwriter, threatened or contemplated by the Commission, and any request of the Commission for additional information (to be included in the Registration Statement, the Prospectus or the Disclosure Package or otherwise) shall have been complied with to the reasonable satisfaction of the Representative.

     (b) No Underwriter shall have advised the Issuer on or prior to the Closing Date (and, if applicable, each Option Closing Date), that the Registration Statement, the Prospectus or the

Disclosure Package or any amendment or supplement thereto contains an untrue statement of fact which, in the opinion of the Underwriters (upon the advice of counsel) is material, or omits to state a fact which, in the opinion of the Underwriters (upon the advice of counsel) is material and is required to be stated therein or is necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

     (c) On the Closing Date (and, if applicable, each Option Closing Date), the Representative shall have received the opinion of Stinson Morrison Hecker LLP, counsel for the Issuer, addressed to it and dated the Closing Date (and, if applicable, each Option Closing Date), in form and substance reasonably satisfactory to the Representative, to the effect set forth on Exhibit C hereto.

     (d) On the Closing Date (and, if applicable, each Option Closing Date), the Representative shall have received the opinion of Brownstein Hyatt Farber Schreck, LLP, special Nevada counsel for the Issuer, addressed to it and dated the Closing Date (and, if applicable, each Option Closing Date), in form and substance reasonably satisfactory to the Representative, to the effect set forth on Exhibit D hereto.

     (e) The Representative shall have received on the Closing Date (and, if applicable, each Option Closing Date), from Fulbright & Jaworski L.L.P., counsel to the Underwriters, such opinion or opinions, dated the Closing Date (and, if applicable, each Option Closing Date) with respect to such matters as the Representative may reasonably require; and the Issuer shall have furnished to such counsel such documents as they reasonably request for the purposes of enabling them to review or pass on the matters referred to in this Section 6 and in order to evidence the accuracy, completeness and satisfaction of the representations, warranties and conditions herein contained.

     (f) The Representative shall have received letters addressed to the Underwriters and dated the date hereof and the Closing Date or each Option Closing Date, as the case may be, from the firm of Murrell, Hall, McIntosh & Co., independent certified public accountants, (i) confirming that they are an independent registered public accounting firm within the meaning of the Securities Act and the Exchange Act, adopted by the Commission and the Public Company Accounting Oversight Board (United States), and that they have performed a review of the unaudited interim financial information made available by the Issuer for the three-month period ended March 31, 2008 and as of March 31, 2008, in accordance with Statement on Auditing Standards No. 100 and (ii) stating, as of the date thereof (or, with respect to matters involving changes or developments since the respective dates as of which specified financial information is given in the Registration Statement, the Disclosure Package and the Prospectus, as of a date not more than five days prior to the date thereof), the conclusions and findings of such firm with respect to the financial information and other matters ordinarily covered by accountants’ “comfort letters” to underwriters in connection with registered public offerings.

     (g) Subsequent to the Applicable Time or, if earlier, the dates as of which information is given in the Registration Statement (exclusive of any amendment thereof) and the Prospectus

(exclusive of any amendment or supplement thereto), there shall not have been (i) any change or decrease specified in the letter or letters referred to in paragraph (f) of this Section 6 or (ii) any change, or any development involving a prospective change, in or affecting the condition (financial or otherwise), earnings, business or properties of the Issuer taken as a whole or of PetroEdge, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Registration Statement, the Prospectus and the Disclosure Package the effect of which, in any case referred to in clause (i) or (ii) above, is, in the sole judgment of the Representative, so material and adverse as to make it impractical or inadvisable to proceed with the offering or delivery of the Shares as contemplated by the Registration Statement (exclusive of any amendment thereof), the Prospectus and the Disclosure Package (exclusive of any amendment or supplement thereto).

     (h) There shall not have occurred any of the following: (i) a suspension or material limitation in trading in securities generally on the Nasdaq Global Market, or the establishing on such market by the Commission or by such market of minimum or maximum prices which are not in force and effect on the date hereof; (ii) a suspension or material limitation in trading in the Issuer’s securities on the Nasdaq Global Market or the establishing on such market by the Commission or by such market of minimum or maximum prices which are not in force and effect on the date hereof; (iii) a general moratorium on commercial banking activities declared by either federal or applicable state authorities; (iv) the outbreak or escalation of hostilities involving the United States or the declaration by the United States of a national emergency or war, which in the judgment of the Underwriters makes it impracticable or inadvisable to proceed with the public offering or the delivery of the Shares in the manner contemplated in the Registration Statement, the Prospectus and the Disclosure Package; or (v) any calamity or crisis, change in national, international or world affairs, act of God, change in the international or domestic markets, or change in the existing financial, political or economic conditions in the United States or elsewhere, the effect of which on the financial markets of the United States is such as to make it in the judgment of the Underwriters impracticable or inadvisable to proceed with the public offering or the delivery of the Shares in the manner contemplated in the Registration Statement, the Prospectus and the Disclosure Package.

     (i) On the Closing Date (and, if applicable, each Option Closing Date) there shall not have been, since the date hereof or since the respective dates as of which information is given in the Registration Statement, the Disclosure Package and the Prospectus (in each case exclusive of any amendments or supplements thereto subsequent to the date of this Agreement), any Material Adverse Effect, and on the Closing Date (and if applicable, each Option Closing Date) the Representative shall have received certificates, dated the Closing Date (and, if applicable, each Option Closing Date) and signed by chief executive officer and the chief financial officer, in their capacities as such, of the Issuer, to the effect that:

          (i) they have examined the Registration Statement, the Prospectus and the Disclosure Package, and any amendment or supplement thereto, as well as each electronic roadshow used in connection with the offering of the Shares and (A) nothing has come to their attention that would lead them to believe that, as of the Effective Date, the Registration

Statement included any untrue statement of a material fact or omitted to state material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, and as of its issue date and as of the Closing Date (and, if applicable, each Option Closing Date), the Registration Statement, the Prospectus, the Disclosure Package and any amendment or supplement thereto, as well as each electronic roadshow used in connection with the offering of Shares included any untrue statement of a material fact or omitted to state material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, and (B) since the Effective Date, there has occurred no event required to be set forth in an amendment or supplement to the Registration Statement, the Prospectus or the Disclosure Package which has not been so set forth;

          (ii) since the date of the most recent financial statements included in the Registration Statement, the Prospectus and the Disclosure Package, there has been no Material Adverse Effect, except as set forth in or contemplated in the Registration Statement, the Prospectus and the Disclosure Package;

          (iii) all representations and warranties made herein by the Issuer are true and correct as of the Closing Date (or, if applicable, each Option Closing Date), with the same effect as if made on the Closing Date (or, if applicable, each Option Closing Date); and all agreements and conditions herein to be performed or complied with by the Issuer on or prior to the Closing Date (or, if applicable, each Option Closing Date) have been duly performed and complied with by the Issuer;

          (iv) no stop order suspending the effectiveness of the Registration Statement has been issued and no proceeding for that purpose shall have been instituted or, to the knowledge of such officers, threatened by the Commission; and

          (v) the PetroEdge Agreement is in full force and effect, as described in the Registration Statement, the Disclosure Package and the Prospectus, without modification, change or waiver, except for such modifications, changes or waivers as have been specifically identified to the Representative and which, in the judgment of the Representative, do not make it impracticable or inadvisable to proceed with the offering and delivery of the Shares on the Closing Date on the terms and in the manner contemplated in the Registration Statement, the Prospectus and the Disclosure Package.

     (j) The Issuer shall not have failed, refused, or been unable, at or prior to the Closing Date (and, if applicable, each Option Closing Date) to have performed any agreement on its part required to be performed hereby, or any of the conditions herein contained and required to be performed or satisfied by it at or prior to such Closing Date (or, if applicable, each Option Closing Date).

     (k) The Issuer shall have furnished to the Underwriters at the Closing Date (and, if applicable, each Option Closing Date) such further information, opinions, certificates and documents as the Representative may have reasonably requested.

     (l) The Firm Securities and the Option Securities, if any, shall have been approved for designation upon notice of issuance on the Nasdaq Global Market, and satisfactory evidence of such approval shall have been provided to the Representative.

     (m) The Representative shall have received duly and validly executed Lockup Agreements described in Exhibit B and such agreements shall be in full force and effect.

     (n) At the Applicable Time, the Representative shall have received from each of Cawley, Gillespie & Associates, Inc. and DeGolyer and MacNaughton a letter, in form and substance reasonably satisfactory to the Representative, addressed to the Representative and dated the date hereof, stating the conclusions and findings of such firm with respect to the Issuer’s oil and gas reserves in the case of Cawley, Gillespie & Associates, Inc. and PetroEdge’s oil and gas reserves in the case of DeGolyer and MacNaughton as is customary to underwriters in connection with registered public offerings.

     (o) With respect to the letters of Cawley, Gillespie & Associates, Inc. and DeGolyer and MacNaughton referred to in the preceding paragraph and delivered to the Representative concurrently with the execution of this Agreement, the Issuer shall have furnished to the Representative a letter of each such reserve engineers, addressed to the Representative and dated the Closing Date (and, if applicable, each Option Closing Date) confirming in all material respects covering the matters in the letters referred to in the preceding paragraph.

     All such opinions, certificates, letters and documents will be in compliance with the provisions hereof only if they are reasonably satisfactory in form and substance to the Representative and to Fulbright & Jaworski L.L.P., counsel for the several Underwriters. The Issuer will furnish the Representative with such signed and conformed copies of such opinions, certificates, letters and documents as they may request.

     If any of the conditions hereinabove provided for in this Section shall not have been fulfilled when and as required by this Agreement to be fulfilled, the obligations of the Underwriters hereunder may be terminated by the Representative.

     In such event, the Issuer and the Underwriters shall not be under any obligation to each other (except to the extent provided in Sections 5 and 8 hereof).

7. Conditions of the Obligations of the Issuer.

     The obligations of the Issuer to sell and deliver the portion of the Shares required to be delivered as and when specified in this Agreement are subject to the conditions that at the Closing Date or the Option Closing Date, if any, no stop order suspending the effectiveness of the

Registration Statement shall have been issued and in effect or proceedings therefor initiated or threatened.

8. Indemnification.

     (a) The Issuer agrees:

          (i) to indemnify and hold harmless each Underwriter and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, against any losses, claims, damages or liabilities to which such Underwriter or any such controlling person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in (A) the Registration Statement, any Preliminary Prospectus, the Prospectus or any amendment or supplement thereto, (B) any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) (other than any “issuer information” contained in any Offering Participant Free Writing Prospectus) or (C) any “issuer information” contained in any “road show” (each as defined in Rule 433 of the Rules and Regulations) not constituting an Issuer Free Writing Prospectus (such information, a “Non-Prospectus Road Show”) or (ii) the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; provided, however, that the Issuer will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement, or omission or alleged omission made in the Registration Statement, any Preliminary Prospectus, the Prospectus, or such amendment or supplement, any Issuer Free Writing Prospectus or issuer information filed or required to be filed pursuant to Rule 433(d) under the Securities Act or any Non-Prospectus Road Show in reliance upon and in conformity with written information furnished to the Issuer by or through the Representative specifically for use in the preparation thereof, such information being listed in Section 13 below.

          (ii) to reimburse each Underwriter and each such controlling person upon demand for any legal or other out-of-pocket expenses reasonably incurred by such Underwriter or such controlling person in connection with investigating or defending any such loss, claim, damage or liability, action or proceeding or in responding to a subpoena or governmental inquiry related to the offering of the Shares, whether or not such Underwriter or controlling person is a party to any action or proceeding. In the event that it is finally judicially determined that the Underwriters were not entitled to receive payments for legal and other expenses pursuant to this subparagraph, the Underwriters will promptly return all sums that had been advanced pursuant hereto.

     (b) Each Underwriter severally and not jointly will indemnify and hold harmless the Issuer, each of its directors, each of its officers who have signed the Registration Statement and each person, if any, who controls the Issuer within the meaning of Section 15 of the Securities

Act or Section 20 of the Exchange Act, against any losses, claims, damages or liabilities to which the Issuer or any such director, officer or controlling person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings 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 Registration Statement, any Preliminary Prospectus, the Prospectus or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any Offering Participant Free Writing Prospectus, or (ii) the omission or the alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; and upon demand will reimburse any legal or other expenses reasonably incurred by the Issuer or any such director, officer or controlling person in connection with investigating or defending any such loss, claim, damage, liability, action or proceeding; provided, however, that each Underwriter will be liable in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission has been made in the Registration Statement, any Preliminary Prospectus, the Prospectus or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any Offering Participant Free Writing Prospectus in reliance upon and in conformity with written information furnished to the Issuer by or through the Representative specifically for use in the preparation thereof, such information being listed in Section 13 below.

     (c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to this Section, such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing. No indemnification provided for in Section 8(a) or (b) shall be available to any party who shall fail to give notice as provided in this Subsection if the party to whom notice was not given was unaware of the proceeding to which such notice would have related and was materially prejudiced by the failure to give such notice, but the failure to give such notice shall not relieve the indemnifying party or parties from any liability which it or they may have to the indemnified party for contribution or otherwise than on account of the provisions of Section 8(a) or (b). In case any such proceeding shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party and shall pay as incurred the fees and disbursements of such counsel related to such proceeding, and shall not be liable to such indemnified party for any legal or other expenses, except as provided below and except for the reasonable costs of investigation subsequently incurred by such indemnified party in connection with the defense thereof. In any such proceeding, any indemnified party shall have the right to retain its own counsel at its own expense. Notwithstanding the foregoing, the indemnifying party shall pay as incurred (or within 30 days of presentation) the fees and expenses of the counsel retained by the indemnified party in the event (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and the indemnified party shall have reasonably

concluded that representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them or (iii) the indemnifying party shall have failed to assume the defense and employ counsel reasonably acceptable to the indemnified party within a reasonable period of time after notice of commencement of the action.

     It is understood that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate firm for all such indemnified parties. Such firm shall be designated in writing by the Representative in the case of parties indemnified pursuant to Section 8(a) and by the Issuer in the case of parties indemnified pursuant to Section 8(b). The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent but if settled with such consent or if there be a final judgment for the plaintiff (other than a final judgment entered into pursuant to a settlement as to which the indemnifying party did not consent), the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. In addition, the indemnifying party will not, without the prior written consent of the indemnified party, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding of which indemnification may be sought hereunder (whether or not any indemnified party is an actual or potential party to such claim, action or proceeding) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action or proceeding.

     (d) If the indemnification provided for in this Section is unavailable to or insufficient to hold harmless an indemnified party under Section 8(a) or (b) above in respect of any losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Issuer on the one hand and the Underwriters on the other from the offering of the Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Issuer on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions or proceedings in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Issuer on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Issuer bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative fault 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 Issuer on the one hand or the Underwriters on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

     (e) The Issuer and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Subsection were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Subsection. The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to above in this Subsection shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8, (i) no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the shares underwritten by it and distributed to the public were offered to the public exceeds the amount of damages which such Underwriter has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission and (ii) 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 this Section 8(e), each person, if any, who controls an Underwriter 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 Underwriter, and each director of the Issuer, each officer of the Issuer who signed the Registration Statement, and each person, if any, who controls the Issuer within the meaning of the Section 15 of the Securities Act or Section 20 of the Exchange Act, shall have the same rights to contribution as the Issuer. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim for contribution may be made against another party or parties under this Section 8(e), notify in writing such party or parties from whom contribution may be sought, but the omission so to notify such party or parties from whom contribution may be sought shall not relieve the party or parties from whom contribution may be sought from any other obligation it or they may have under this Section 8(e) or otherwise. No party shall be liable for contribution with respect to any action, suit, proceeding or claim settled without its written consent. The Underwriters’ obligations in this Subsection to contribute are several in proportion to their respective underwriting obligations and not joint.

     (f) The indemnity and contribution agreements contained in this Section and the representations and warranties of the Issuer set forth in this Agreement shall remain operative and in full force and effect, regardless of (i) any investigation made by or on behalf of any Underwriter or any person controlling any Underwriter, the Issuer, its directors or officers or any persons controlling the Issuer, (ii) acceptance of any Shares and payment therefor hereunder, and (iii) any termination of this Agreement. A successor to any Underwriter, or to the Issuer, its directors or officers, or any person controlling the Issuer, shall be entitled to the benefits of the indemnity, contribution and reimbursement agreements contained in this Section.

9. Default by Underwriters.

     If on the Closing Date or the Option Closing Date, if any, any Underwriter shall fail to purchase and pay for the portion of the Shares which such Underwriter has agreed to purchase and

pay for on such date (otherwise than by reason of any default on the part of the Issuer), RBC, as the Representative of the Underwriters, shall use its reasonable efforts to procure within 36 hours thereafter one or more of the other Underwriters, or any others, to purchase from the Issuer such amounts as may be agreed upon and upon the terms set forth herein, the Firm Securities or Option Securities, as the case may be, which the defaulting Underwriter or Underwriters failed to purchase. If, however, the Representative shall not have completed such arrangements within such 36-hour period, then the Issuer shall be entitled to a further period of 36 hours within which to procure another party or other parties reasonably satisfactory to the non-defaulting Underwriters to purchase such Shares on such terms. After giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the Representative and the Issuer as provided above, if during such period the Representative or the Issuer shall not have procured such other Underwriters, or any others, to purchase the Firm Securities or Option Securities, as the case may be, agreed to be purchased by the defaulting Underwriter or Underwriters, then (a) if the aggregate number of shares with respect to which such default shall occur does not exceed 10% of the Firm Securities or Option Securities, as the case may be, covered hereby, the other Underwriters shall be obligated, severally, in proportion to the respective numbers of Firm Securities or Option Securities, as the case may be, which they are obligated to purchase hereunder, to purchase the Firm Securities or Option Securities, as the case may be, which such defaulting Underwriter or Underwriters failed to purchase, or (b) if the aggregate number of shares of Firm Securities or Option Securities, as the case may be, with respect to which such default shall occur exceeds 10% of the Firm Securities or Option Securities, as the case may be, covered hereby, the Issuer or RBC will have the right to terminate this Agreement without liability on the part of the non-defaulting Underwriters or of the Issuer except to the extent provided in Section 5 and 8 hereof. In the event of a default by any Underwriter or Underwriters, as set forth in this Section, the Closing Date or Option Closing Date, if any, may be postponed for such period, not exceeding seven days, as RBC, as the Representative, or the Issuer may determine in order that the required changes in the Registration Statement or in the Prospectus or in any other documents or arrangements may be effected; provided, that RBC, as the Representative, and the Issuer shall endeavor to keep such postponement period as short as reasonably practicable. The term “Underwriter” includes any person substituted for a defaulting Underwriter. Any action taken under this Section shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

11. Termination.

     (a) This Agreement may be terminated by the Representative at any time (i) at or prior to the Closing Date by notice to the Issuer if any condition specified in Section 6 hereof shall not have been satisfied on or prior to the Closing Date or (ii) as provided in Section 9 of this Agreement. Any such termination shall be without liability of any party to any other party except as provided in Sections 5 and 8 hereof.

     If the Representative terminates this Agreement as provided in Sections 11(a) or 11(b), it shall notify the Issuer by telephone or facsimile transmission, confirmed by letter.

12. Successors.

     This Agreement has been and is made solely for the benefit of the Issuer and Underwriters and their respective successors and assigns, and the officers, directors and controlling persons referred to herein, and no other person will have any right or obligation hereunder. No purchaser of

any of the Shares from any Underwriter shall be deemed a successor or assign merely because of such purchase.

13. Information Provided by Underwriters.

     The Issuer and the Underwriters acknowledge and agree that the only information furnished or to be furnished by any Underwriter to the Issuer for inclusion in the Prospectus, any Issuer Free Writing Prospectus or the Registration Statement consists of the information contained in (a) the last sentence of the cover page of the Preliminary Prospectus and the Prospectus (regarding the date of delivery of shares of common stock in book-entry form), (b) the fourth, sixteenth, seventeenth, eighteenth and nineteenth paragraphs under the caption “Underwriting” of the Preliminary Prospectus, the Prospectus and, (c) with respect to each Underwriter, severally but not jointly, any information contained in any Offering Participant Free Writing Prospectus distributed or otherwise used in connection with the offering of the Shares by that Underwriter.

Business and Properties — Recent Developments; — Our Relationship with Quest Energy; — Our Relationship with Quest Midstream; — Environmental Matters and Regulation; — Other Regulation of the Gas and Oil Industry,” and “Item 3. Legal Proceedings,” insofar as they purport to constitute summaries of provisions of federal or Kansas statutes, rules or regulations, the DGCL, the Delaware LP Act or the Delaware LLC Act or of any specific agreement or instrument, constitute accurate summaries thereof in all material respects.

     27. The Registration Statement has been declared effective under the Securities Act; to the knowledge of such counsel, no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or threatened by the Commission; and any required filing of the Prospectus pursuant to Rule 424(b) has been made in the manner and within the time period required by such Rule.
