REGISTRATION RIGHTS AGREEMENT

Section 6.                                           Registration Procedures.  If and whenever the Company is required to use its reasonable best efforts to effect the registration of any Registrable Securities under the Securities Act as provided in Section 3 and Section 4 hereof, the Company shall effect such registration to permit the sale of such Registrable Securities in accordance with the intended method or methods of disposition thereof, and pursuant thereto the Company shall cooperate in the sale of the securities and shall, as expeditiously as possible:

(a)                                 Prepare and file with the SEC a Registration Statement or Registration Statements on such form which shall be available for the sale of the Registrable Securities by the holders thereof in accordance with the intended method or methods of distribution thereof (including, without limitation, a Partner Distribution), and use its reasonable best efforts to cause such Registration Statement to become effective and to remain effective as provided herein; provided, however, that before filing a Registration Statement or Prospectus or any amendments or supplements thereto (including documents that would be incorporated or deemed to be incorporated therein by reference), the Company shall furnish or otherwise make available to the holders of the Registrable Securities covered by such Registration Statement, their counsel and the managing underwriters, if any, copies of all such documents proposed to be filed.  The Company shall not file any such Registration Statement or Prospectus or any amendments or supplements thereto (including such documents that, upon filing, would be incorporated or deemed to be incorporated by reference therein) with respect to a Demand Registration to which the holders of a majority of the Registrable Securities covered by such Registration Statement, their counsel, or the managing underwriters, if any, shall reasonably object, in writing, on a timely basis, unless, in the opinion of the Company, such filing is necessary to comply with applicable law.

(b)                                 Prepare and file with the SEC such amendments and post-effective amendments to each Registration Statement as may be necessary to keep such Registration Statement continuously effective during the period provided herein with respect to the disposition of all securities covered by such Registration Statement; and cause the related Prospectus to be supplemented by any Prospectus supplement as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of the securities covered by such Registration Statement, and as so supplemented to be filed pursuant to Rule 424 (or any similar provisions then in force) under the Securities Act.

(c)                                  Notify each selling holder of Registrable Securities, its counsel and the managing underwriters, if any, promptly, and (if requested by any such Person) confirm such notice in writing, (i) when a Prospectus or any Prospectus supplement or post-effective amendment has been filed, and, with respect to a Registration Statement or any post-effective amendment, when the same has become effective, (ii) of any request by the SEC or any other federal or state governmental authority for amendments or supplements to a Registration Statement or related Prospectus or for additional information, (iii) of the issuance by the SEC of any stop order suspending the effectiveness of a Registration Statement or the initiation of any proceedings for that purpose, (iv) of the receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Registrable Securities for sale in any jurisdiction, or the initiation or threatening of any proceeding for such purpose, and (v) of the happening of any event that makes any statement made in such Registration Statement or related Prospectus or any document incorporated or deemed to be

11

incorporated therein by reference untrue in any material respect or that requires the making of any changes in such Registration Statement, Prospectus or documents so that, in the case of the Registration Statement, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, not misleading, and that in the case of the Prospectus, it will not contain any 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.

(d)                                 Use its reasonable best efforts to obtain the withdrawal of any order suspending the effectiveness of a Registration Statement, or the lifting of any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction.

(e)                                  If requested by the managing underwriters, if any, or the holders of a majority of Registrable Securities being sold in connection with an underwritten offering, promptly include in a Prospectus supplement or post-effective amendment such information as the managing underwriters, if any, and such holders may reasonably request in order to permit the intended method of distribution of such securities and make all required filings of such Prospectus supplement or such post-effective amendment as soon as practicable after the Company has received such request; provided, however, that the Company shall not be required to take any actions under this Section 6(e) that are not, in the opinion of counsel for the Company, in compliance with applicable law.

(f)                                   Furnish or make available to each selling holder of Registrable Securities, its counsel and each managing underwriter, if any, without charge, at least one (1) copy of the Registration Statement, the Prospectus and Prospectus supplements, if applicable, and each post-effective amendment thereto, including financial statements (but excluding schedules, all documents incorporated or deemed to be incorporated therein by reference, and all exhibits, unless requested in writing by such holder, counsel or underwriter).

(g)                                  Deliver to each selling holder of Registrable Securities, its counsel, and the underwriters, if any, without charge, as many copies of the Prospectus or Prospectuses (including each form of Prospectus) and each amendment or supplement thereto as such Persons may reasonably request in connection with the distribution of the Registrable Securities; and the Company, subject to the last paragraph of this Section 6, hereby consents to the use of such Prospectus and each amendment or supplement thereto by each of the selling holders of Registrable Securities and the underwriters, if any, in connection with the offering and sale of the Registrable Securities covered by such Prospectus and any such amendment or supplement thereto.

(h)                                 Prior to any public offering of Registrable Securities, use its reasonable best efforts to register or qualify or cooperate with the selling holders of Registrable Securities, the underwriters, if any, and their respective counsel in connection with the registration or qualification (or exemption from such registration or qualification) of such Registrable Securities for offer and sale under the securities or “Blue Sky” laws of such jurisdictions within the United States as any seller or underwriter reasonably requests in writing and to keep each such registration or qualification (or exemption therefrom) effective during the

12

period such Registration Statement is required to be kept effective and to take any other action that may be necessary or advisable to enable such holders of Registrable Securities to consummate the disposition of such Registrable Securities in such jurisdiction; provided, however, that the Company will not be required to (i) qualify generally to do business in any jurisdiction where it is not then so qualified or (ii) take any action that would subject it to general service of process in any such jurisdiction where it is not then so subject.

(i)                                     Cooperate with the selling holders of Registrable Securities and the managing underwriters, if any, to facilitate the timely preparation and delivery of certificates (not bearing any legends) representing Registrable Securities to be sold after receiving written representations from each holder of such Registrable Securities that the Registrable Securities represented by the certificates so delivered by such holder will be transferred in accordance with the Registration Statement, and enable such Registrable Securities to be in such denominations and registered in such names as the managing underwriters, if any, or holders may request at least two (2) business days prior to any sale of Registrable Securities in a firm commitment public offering, but in any other such sale, within ten (10) business days prior to having to issue the securities.

(j)                                    Upon the occurrence of any event contemplated by Section 6(c)(v) above, prepare a supplement or post-effective amendment to the Registration Statement or a supplement to the related Prospectus or any document incorporated or deemed to be incorporated therein by reference, or file any other required document so that, as thereafter delivered to the purchasers of the Registrable Securities being sold thereunder, such Prospectus will not 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 were made, not misleading.

(k)                                 Prior to the effective date of the Registration Statement relating to the Registrable Securities, provide a CUSIP number for the Registrable Securities.

(l)                                     Provide and cause to be maintained a transfer agent and registrar for all Registrable Securities covered by such Registration Statement from and after a date not later than the effective date of such Registration Statement.

(m)                             Use its reasonable best efforts to cause all Registrable Securities covered by such Registration Statement to be authorized to be quoted on the Nasdaq Stock Market or listed on a national securities exchange if securities of the particular class of Registrable Securities are at that time quoted on the Nasdaq Stock Market or listed on such exchange, as the case may be.

(n)                                 Enter into such agreements (including an underwriting agreement in form, scope and substance as is customary in underwritten offerings) and take all such other actions reasonably requested by the holders of a majority of the Registrable Securities being sold in connection therewith (including those reasonably requested by the managing underwriters, if any) to expedite or facilitate the disposition of such Registrable Securities, and in such connection, whether or not an underwriting agreement is entered into and whether or not the registration is an underwritten registration, (i) make such representations and warranties to the

13

holders of such Registrable Securities and the underwriters, if any, with respect to the business of the Company and its subsidiaries, and the Registration Statement, Prospectus and documents, if any, incorporated or deemed to be incorporated by reference therein, in each case, in form, substance and scope as are customarily made by issuers to underwriters in underwritten offerings, and, if true, confirm the same if and when requested, (ii) use its reasonable best efforts to furnish to the selling holders of such Registrable Securities opinions of counsel to the Company and updates thereof (which counsel and opinions (in form, scope and substance) shall be reasonably satisfactory to the managing underwriters, if any, and counsels to the selling holders of the Registrable Securities), addressed to each selling holder of Registrable Securities and each of the underwriters, if any, covering the matters customarily covered in opinions requested in underwritten offerings and such other matters as may be reasonably requested by such counsel and underwriters, (iii) use its reasonable best efforts to obtain “cold comfort” letters and updates thereof from the independent certified public accountants of the Company (and, if necessary, any other independent certified public accountants of any subsidiary of the Company or of any business acquired by the Company for which financial statements and financial data are, or are required to be, included in the Registration Statement) who have certified the financial statements included in such Registration Statement, addressed to each selling holder of Registrable Securities (unless such accountants shall be prohibited from so addressing such letters by applicable standards of the accounting profession) and each of the underwriters, if any, such letters to be in customary form and covering matters of the type customarily covered in “cold comfort” letters in connection with underwritten offerings, (iv) use its reasonable best efforts to obtain a report of the independent petroleum engineers of the Company relating to the oil and gas reserves of the Company included in such Registration Statement if the Company has had its reserves prepared, audited or reviewed by an independent petroleum engineer, such report to be in customary form and covering matters of the type customarily covered in such reports, (v)if an underwriting agreement is entered into, the same shall contain indemnification provisions and procedures substantially to the effect set forth in Section 8 hereof with respect to all parties to be indemnified pursuant to said Section and (vi) deliver such documents and certificates as may be reasonably requested by the holders of a majority of the Registrable Securities being sold, their counsel and the managing underwriters, if any, to evidence the continued validity of the representations and warranties made pursuant to Section 6(n)(i) above and to evidence compliance with any customary conditions contained in the underwriting agreement or other agreement entered into by the Company.  The above shall be done at each closing under such underwriting or similar agreement, or as and to the extent required thereunder.

(o)                                 Make available for inspection by a representative of the selling holders of Registrable Securities, any underwriter participating in any such disposition of Registrable Securities, if any, and any attorneys or accountants retained by such selling holders or underwriter, at the offices where normally kept, during reasonable business hours, all financial and other records, pertinent corporate documents and properties of the Company and its subsidiaries, and cause the officers, directors and employees of the Company and its subsidiaries to supply all information in each case reasonably requested by any such representative, underwriter, attorney or accountant in connection with such Registration Statement; provided, however, that any information that is not generally publicly available at the time of delivery of such information shall be kept confidential by such Persons unless (i) disclosure of such information is required by court or administrative order, (ii) disclosure of such information, in the opinion of counsel to such Person, is required by law, or (iii) such information becomes

14

generally available to the public other than as a result of a disclosure or failure to safeguard by such Person.  In the case of a proposed disclosure pursuant to (i) or (ii) above, such Person shall be required to give the Company written notice of the proposed disclosure prior to such disclosure and, if requested by the Company, assist the Company in seeking to prevent or limit the proposed disclosure.  Without limiting the foregoing, no such information shall be used by such Person as the basis for any market transactions in securities of the Company or its subsidiaries in violation of law.

(p)                                 Comply with all applicable rules and regulations of the SEC and make available to its security holders earning statements satisfying the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder, or any similar rule promulgated under the Securities Act, no later than ninety (90) days after the end of any twelve (12) month period (or such shorter period of time as may be required under the Securities Act) (i) commencing at the end of any fiscal quarter in which Registrable Securities are sold to underwriters in a firm commitment or best efforts underwritten offering and (ii) if not sold to underwriters in such an offering, commencing on the first day of the first fiscal quarter of the Company after the effective date of a Registration Statement, which statements shall cover one of said twelve (12) month periods.

(q)                                 Cause its officers to use their reasonable best efforts to support the marketing of the Registrable Securities covered by the Registration Statement (including, without limitation, participation in “road shows”) taking into account the Company’s business needs.

The Company may require each seller of Registrable Securities as to which any registration is being effected to furnish to the Company in writing such information required in connection with such registration regarding such seller and the distribution of such Registrable Securities as the Company may, from time to time, reasonably request in writing and the Company may exclude from such registration the Registrable Securities of any seller who unreasonably fails to furnish such information within a reasonable time after receiving such request.

Each holder of Registrable Securities agrees if such holder has Registrable Securities covered by such Registration Statement that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 6(c)(ii), 6(c)(iii), 6(c)(iv) or 6(c)(v) hereof, such holder will forthwith discontinue disposition of such Registrable Securities covered by such Registration Statement or Prospectus until such holder’s receipt of the copies of the supplemented or amended Prospectus contemplated by Section 6(j) hereof, or until it is advised in writing by the Company that the use of the applicable Prospectus may be resumed, and has received copies of any additional or supplemental filings that are incorporated or deemed to be incorporated by reference in such Prospectus; provided, however, that the Company shall extend the time periods under Section 3 with respect to the length of time that the effectiveness of a Registration Statement must be maintained by the amount of time the holder is required to discontinue disposition of such securities.

Section 7.                                           Registration Expenses.  All reasonable fees and expenses incident to the performance of or compliance with this Agreement by the Company (including, without

15

limitation, (a) all registration and filing fees (including, without limitation, fees and expenses (i)with respect to filings required to be made with the National Association of Securities Dealers, Inc. and (ii) of compliance with securities or Blue Sky laws, including, without limitation, any fees and disbursements of counsel for the underwriters in connection with Blue Sky qualifications of the Registrable Securities pursuant to Section 6(h)), (b) printing expenses (including, without limitation, expenses of printing certificates for Registrable Securities in a form eligible for deposit with The Depository Trust Company and of printing Prospectuses if the printing of Prospectuses is requested by the managing underwriters, if any, or by the holders of a majority of the Registrable Securities included in any Registration Statement), (c) messenger, telephone and delivery expenses of the Company, (d) fees and disbursements of counsel for the Company, (e) expenses of the Company incurred in connection with any road show, (f) fees and disbursements of all independent certified public accountants referred to in Section 6(n)(iii) hereof (including, without limitation, the expenses of any “cold comfort” letters or oil and gas reserve reports required by this Agreement) and any other persons, including special experts retained by the Company, and (g) fees and disbursements of one counsel for the holders of Registrable Securities whose securities are included in a Registration Statement, which counsel shall be selected by the holders of a majority of the Registrable Securities included in such Registration Statement shall be borne by the Company or any of its Subsidiaries whether or not any Registration Statement is filed or becomes effective.  In addition, the Company or any of its Subsidiaries shall pay its internal expenses (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), the expense of any annual audit, the fees and expenses incurred in connection with the listing of the securities to be registered on any securities exchange on which similar securities issued by the Company are then listed and rating agency fees and the fees and expenses of any Person, including special experts, retained by the Company.

Section 8.                                           Indemnification.

(a)                                 Indemnification by the Company.  The Company shall, without limitation as to time, indemnify and hold harmless, to the fullest extent permitted by law, each holder of Registrable Securities whose Registrable Securities are covered by a Registration Statement or Prospectus, the officers, directors, partners, members, managers, stockholders, accountants, attorneys, agents and employees of each of them, each Person who controls each such holder (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and the officers, directors, partners, members, managers, stockholders, accountants, attorneys, agents and employees of each such controlling person, each underwriter, if any, and each Person who controls (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) such underwriter, from and against any and all losses, claims,

16

damages, liabilities, costs (including, without limitation, costs of preparation and reasonable attorneys’ fees and any legal or other fees or expenses incurred by such party in connection with any investigation or Proceeding), expenses, judgments, fines, penalties, charges and amounts paid in settlement (collectively, “Losses”), as incurred, arising out of or based upon (i) any untrue statement (or alleged untrue statement) of a material fact contained in a Registration Statement, any preliminary Prospectus or final Prospectus contained therein or otherwise filed with the SEC, any amendment or supplement thereto, any document incorporated by reference therein, any “issuer free writing prospectus” (as defined in Rule 433 promulgated under the Securities Act) or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act (in each case relating to the Registrable Securities) or any other document incident to registration or qualification of such Registrable Securities, (ii) any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or (iii) any violation by the Company of the Securities Act or any rule or regulation thereunder applicable to the Company and relating to action or inaction required of the Company in connection with any such registration, qualification, or compliance, and will reimburse each such holder, each of its officers, directors, partners, members, managers, stockholders, accountants, attorneys, agents and employees and each person controlling such holder, each such underwriter, and each person who controls any such underwriter, for any legal and any other expenses reasonably incurred in connection with investigating and defending or settling any such claim, loss, damage, liability, or action, provided, that the Company will not be liable in any such case to the extent that any such claim, loss, damage, liability, or expense arises out of or is based on any untrue statement or omission by such holder or underwriter, but only to the extent, that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in such Registration Statement, preliminary Prospectus, final Prospectus, amendment, supplement, issuer free writing prospectus or document incident to registration or qualification of any Registrable Securities in reliance upon and in conformity with written information furnished to the Company by such holder.  It is agreed that the indemnity agreement contained in this Section 8(a) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability, or action if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld).

(b)                                 Indemnification by Holder of Registrable Securities.  In connection with any Registration Statement in which a holder of Registrable Securities is participating, such holder of Registrable Securities shall furnish to the Company in writing such information as the Company reasonably requests for use in connection with any Registration Statement, preliminary Prospectus, final Prospectus, amendment, supplement, issuer free writing prospectus or document incident to registration or qualification of any Registrable Securities and agrees to indemnify, to the fullest extent permitted by law, severally and not jointly, the Company, its directors, officers, accountants, attorneys, agents and employees, each Person who controls the Company (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, partners, members, managers, stockholders, accountants, attorneys, agents or employees of such controlling persons, and each underwriter, if any, and each person who controls such underwriter (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), from and against all Losses arising out of or based on any untrue statement of a material fact contained in any such Registration Statement, preliminary Prospectus, final Prospectus, amendment, supplement, issuer free writing prospectus

17

or document incident to registration or qualification of any Registrable Securities or any omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse the Company and such directors, officers, partners, members, managers, stockholders, accountants, attorneys, employees, agents, persons, underwriters, or control persons for any legal or any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability, or action, in each case to the extent, but only to the extent, that such untrue statement or omission is made in such Registration Statement, preliminary Prospectus, final Prospectus, amendment, supplement, issuer free writing prospectus or document incident to registration or qualification of any Registrable Securities in reliance upon and in conformity with written information furnished to the Company by such holder specifically for use in connection with the preparation of such Registration Statement, preliminary Prospectus, final Prospectus, amendment, supplement, issuer free writing prospectus or document incident to registration or qualification of any Registrable Securities; provided, however, that the obligations of such holder hereunder shall not apply to amounts paid in settlement of any such claims, losses, damages, or liabilities (or actions in respect thereof) if such settlement is effected without the consent of such holder (which consent shall not be unreasonably withheld); and provided, further, that the liability of each selling holder of Registrable Securities hereunder shall be limited to the net proceeds received by such selling holder from the sale of Registrable Securities covered by such Registration Statement.

(c)                                  Conduct of Indemnification Proceedings.  If any Person shall be entitled to indemnity hereunder (an “indemnified party”), such indemnified party shall give prompt notice to the party from which such indemnity is sought (the “indemnifying party”) of any claim or of the commencement of any Proceeding with respect to which such indemnified party seeks indemnification or contribution pursuant hereto; provided, however, that the delay or failure to so notify the indemnifying party shall not relieve the indemnifying party from any obligation or liability except to the extent that the indemnifying party has been prejudiced by such delay or failure.  The indemnifying party shall have the right, exercisable by giving written notice to an indemnified party promptly after the receipt of written notice from such indemnified party of such claim or Proceeding, to, unless in the indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist in respect of such claim, assume, at the indemnifying party’s expense, the defense of any such claim or Proceeding, with counsel reasonably satisfactory to such indemnified party; provided, however, that an indemnified party shall have the right to employ separate counsel in any such claim or Proceeding and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless:  (i) the indemnifying party agrees to pay such fees and expenses; or (ii) the indemnifying party fails promptly to assume or in the event of a conflict of interest cannot assume the defense of such claim or Proceeding or fails to employ counsel reasonably satisfactory to such indemnified party; in which case the indemnified party shall have the right to employ counsel and to assume the defense of such claim or proceeding; provided, however, that the indemnifying party shall not, in connection with any one such claim or Proceeding or separate but substantially similar or related claims or Proceedings in the same jurisdiction, arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one firm of attorneys (together with appropriate local counsel) at any time for all of the indemnified parties, or for fees and expenses that are not reasonable.  Whether or not such defense is assumed by the indemnifying party, such indemnified party will not be subject to any liability for any settlement made without its consent (but such consent will not be

18

unreasonably withheld).  The indemnifying party shall not consent to entry of any judgment or enter into any settlement that does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release, in form and substance reasonably satisfactory to the indemnified party, from all liability in respect of such claim or litigation for which such indemnified party would be entitled to indemnification hereunder.

(d)                                 Contribution.  If the indemnification provided for in this Section 8 is unavailable to an indemnified party in respect of any Losses (other than in accordance with its terms), then each applicable indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such Losses, in such proportion as is appropriate to reflect the relative fault of the indemnifying party, on the one hand, and such indemnified party, on the other hand, in connection with the actions, statements or omissions that resulted in such Losses as well as any other relevant equitable considerations.  The relative fault of such indemnifying party, on the one hand, and indemnified party, on the other hand, shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, has been taken by, or relates to information supplied by, such indemnifying party or indemnified party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent any such action, statement or omission.

The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 8(d) were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in the immediately preceding paragraph.  Notwithstanding the provisions of this Section 8(d), an indemnifying party that is a selling holder of Registrable Securities shall not be required to contribute any amount in excess of the amount by which the net proceeds from the sale of the Registrable Securities sold by such indemnifying party exceeds the amount of any damages that such indemnifying party has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.  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.

(e)                                  Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained in the underwriting agreement entered into in connection with the underwritten public offering are in conflict with the foregoing provisions, the provisions in the underwriting agreement shall control.

Section 9.                                           Rule 144.  After the Initial Public Offering, the Company shall file the reports required to be filed by it under the Securities Act and the Exchange Act, and will take such further action as any holder of Registrable Securities may reasonably request, all to the extent required from time to time to enable such holder to sell Registrable Securities without registration under the Securities Act within the limitations of the exemption provided by Rule 144.  Upon the request of any holder of Registrable Securities, the Company shall deliver to such holder a written statement as to whether it has complied with such requirements.

19

Section 10.                                    Underwritten Registrations.  Following the Initial Public Offering, if a Demand Registration is an underwritten offering, the Initiating Holders shall have the right to select the investment banker or investment bankers and managers to administer the offering, subject to approval by the Company, not to be unreasonably withheld.  The Company shall have the right to select the investment banker or investment bankers and managers to administer any Piggyback Registration.

No Person may participate in any underwritten registration hereunder unless such Person (a) agrees to sell the Registrable Securities it desires to have covered by the Demand Registration on the basis provided in any underwriting arrangements in customary form and (b) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents required under the terms of such underwriting arrangements, provided, that such Person shall not be required to make any representations or warranties other than those related to title and ownership of Units (or Antero Resources Common Stock, as the case may be) and as to the accuracy and completeness of statements made in a Registration Statement, Prospectus, offering circular, or other document in reliance upon and in conformity with written information furnished to the Company or the managing underwriter by such Person.

Section 11.                                    Limitation on Subsequent Registration Rights.  From and after the date of this Agreement, the Company shall not, without Required Member Approval, enter into any agreement with any holder or prospective holder of any securities of the Company giving such holder or prospective holder any registration rights the terms of which are equivalent to or more favorable than the registration rights granted to holders of Registrable Securities hereunder, or which would reduce the amount of Registrable Securities the holders can include in any registration filed pursuant to Section 3 hereof, unless such rights are subordinate to those of the holders of Registrable Securities.

Section 12.                                    Miscellaneous.

(a)                                 Amendments and Waivers.  The provisions of this Agreement, including the provisions of this sentence, may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, unless the Company has obtained Required Member Approval; provided, however, that in no event shall the obligations of any holder of Registrable Securities be materially increased or the rights of any Member be adversely affected (without similarly adversely affecting the rights of all Members), except upon the written consent of such holder.  Notwithstanding the foregoing, a waiver or consent to depart from the provisions hereof with respect to a matter that relates exclusively to the rights of holders of Registrable Securities whose securities are being sold pursuant to a Registration Statement and that does not directly or indirectly affect the rights of other holders of Registrable Securities may be given by holders of at least sixty-seven percent (67%) of the Registrable Securities being sold by such holders pursuant to such Registration Statement.

(b)                                 Notices.  All notices required to be given hereunder shall be in writing and shall be deemed to be duly given if personally delivered, telecopied and confirmed, or mailed by certified mail, return receipt requested, or overnight delivery service with proof of receipt maintained, at the following address (or any other address that any such party may designate by written notice to the other parties):

Each of the parties hereto hereby consents to process being served by any party to this Agreement in any suit, action, or proceeding of the nature specified in the paragraph above by the mailing of a copy thereof in the manner specified by the provisions of subsection (b) of this Section 12.
