The Registration Statement filed with the Commission pursuant to this Section 2.01 shall be on Form S-1 or such other form of registration statement as is then available to effect a registration for resale of such Registrable Securities, covering such Registrable Securities, and shall contain a Prospectus in such form as to permit any Holder to sell such Registrable Securities pursuant to Rule 415 under the Securities Act (or any successor or similar provision adopted by the Commission then in effect) at any time beginning on the effective date for such Registration Statement. A Registration Statement filed pursuant to this Section 2.01 shall provide for the resale pursuant to any method or combination of methods legally available to, and requested by, the Holders. The Company shall use its reasonable best efforts to cause a Registration Statement filed pursuant to this Section 2.01 to remain effective, and to be supplemented and amended to the extent necessary to ensure that such Registration Statement is available or, if not available, that another registration statement is available, for the resale of all the Registrable Securities held by the Holders until all such

6

Registrable Securities have ceased to be Registrable Securities. As soon as practicable following the effective date of a Registration Statement filed pursuant to this Section 2.01, but in any event within three (3) Business Days of such date, the Company shall notify the Holders of the effectiveness of such Registration Statement. When effective, a Registration Statement filed pursuant to this Section 2.01 (including any documents incorporated therein by reference) will comply as to form in all material respects with all applicable requirements of the Securities Act and the Exchange Act 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 to make the statements therein not misleading (in the case of any Prospectus contained in such Registration Statement, in the light of the circumstances under which such statement is made).

Section 2.02 Underwritten Offering.

(a) In the event that (i) High Mesa Holdings, (ii) the Kingfisher Contributor or (iii) Riverstone elect to dispose of Registrable Securities under a Registration Statement pursuant to an Underwritten Offering of all or part of such Registrable Securities that are registered by such Registration Statement and reasonably expect aggregate gross proceeds in excess of $50,000,000 (the “Minimum Amount”) from such Underwritten Offering, then the Company shall, upon the written demand of High Mesa Holdings, the Kingfisher Contributor or Riverstone, as the case may be (any such Holder, a “Demanding Holder” and, collectively, the “Demanding Holders”), enter into an underwriting agreement in a form as is customary in Underwritten Offerings of equity securities with the managing Underwriter or Underwriters selected by the Company after consultation with the Demanding Holders and shall take all such other reasonable actions as are requested by the managing Underwriter or Underwriters in order to expedite or facilitate the disposition of such Registrable Securities; provided, however, that the Company shall have no obligation to facilitate or participate in (A) more than six (6) Underwritten Offerings pursuant to this Section 2.02 for High Mesa Holdings, (B) more than three (3) Underwritten Offerings pursuant to this Section 2.02 for the Riverstone Contributor or (C) more than two (2) Underwritten Offerings pursuant to this Section 2.02 for the Kingfisher Contributor (each such amount in (A), (B) or (C), respectively, the “Underwritten Offerings Cap”); provided further that if an Underwritten Offering is commenced but terminated prior to the pricing thereof for any reason, such Underwritten Offering will not be counted as an Underwritten Offering pursuant to this Section 2.02. In addition, the Company shall give prompt written notice to each other Holder regarding such proposed Underwritten Offering, and such notice shall offer such Holders the opportunity to include in the Underwritten Offering such number of Registrable Securities as each such Holder may request. Each such Holder shall make such request in writing to the Company within five (5) business days after the receipt of any such notice from the Company, which request shall specify the number of Registrable Securities intended to be disposed of by such Holder. In connection with any Underwritten Offering contemplated by this Section 2.02, the underwriting agreement into which each Demanding Holder and the Company shall enter shall contain such representations, covenants, indemnities (subject to Article IV) and other rights and obligations as are customary in underwritten offerings of equity securities. No Demanding Holder shall be required to make any representations or warranties to or agreements with the Company or the Underwriters other than representations, warranties or agreements regarding such Demanding Holder’s authority to enter into such underwriting agreement and to sell, and its ownership of, the securities being registered on its behalf, its intended method of distribution and any other representation required by law.

7

(b) If the managing Underwriter or Underwriters in an Underwritten Offering, in good faith, advises the Company and the Demanding Holders that the dollar amount or number of Registrable Securities that the Demanding Holders desire to sell, taken together with all other shares of Class A Common Stock or other equity securities that the Company or any other Holder desires to sell and the shares of Class A Common Stock, if any, as to which a Registration has been requested pursuant to separate written contractual piggy-back registration rights held by any other stockholders who desire to sell, exceeds the maximum dollar amount or maximum number of equity securities that can be sold in the Underwritten Offering without adversely affecting the proposed offering price, the timing, the distribution method, or the probability of success of such offering (such maximum dollar amount or maximum number of such securities, as applicable, the “Maximum Number of Securities”), then the Company shall include in such Underwritten Offering, as follows:

(i) first, the Registrable Securities of the Demanding Holders pro rata based on the respective number of Registrable Securities that each Demanding Holder has requested be included in such Underwritten Offering and the aggregate number of Registrable Securities that the Demanding Holders have requested be included in such Underwritten Offering that can be sold without exceeding the Maximum Number of Securities;

(ii) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (i), shares of Class A Common Stock or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; and

(iii) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (i) and clause (ii), shares of Class A Common Stock or other equity securities of (x) other Holders who have elected to participate in the Underwritten Offering pursuant to Section 2.02(a) or (y) persons or entities that the Company is obligated to register in a Registration pursuant to separate written contractual arrangements with such persons, pro rata, which can be sold without exceeding the Maximum Number of Securities.

(c) A Demanding Holder shall have the right to withdraw all or any portion of its Registrable Securities included in an Underwritten Offering pursuant to this Section 2.02 for any or no reason whatsoever upon written notification to the Company and the Underwriter or Underwriters of its intention to withdraw from such Underwritten Offering prior to the pricing of such Underwritten Offering and such withdrawn amount shall no longer be considered an Underwritten Offering (including, without limitation, for purposes of the Underwritten Offerings Cap); provided, however, that upon the withdrawal of an amount of Registrable Securities that results in the remaining amount of Registrable Securities included by High Mesa Holdings, the Kingfisher Contributor or Riverstone, as the case may be, in such Underwritten Offering being less than the Minimum Amount, the Company shall cease all efforts to complete the

8

Underwritten Offering and, for the avoidance of doubt, such Underwritten Offering shall not count against the Underwritten Offerings Cap. Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the Registration Expenses incurred in connection with an Underwritten Offering prior to its withdrawal under this Section 2.02(c).

Section 2.03 Piggyback Registration.

(a) If at any time the Company proposes to file a Registration Statement under the Securities Act with respect to an Underwritten Offering of equity securities, or securities or other obligations exercisable or exchangeable for, or convertible into equity securities, for its own account or for the account of stockholders of the Company (or by the Company and by the stockholders of the Company including, without limitation, pursuant to Section 2.02 hereof) on a form that would permit registration of Registrable Securities, other than a Registration Statement (i) filed in connection with any employee stock option or other benefit plan, (ii) for an exchange offer or offering of securities solely to the Company’s existing stockholders, (iii) for an offering of debt that is convertible into equity securities of the Company, (iv) for a dividend reinvestment plan or (v) on Form S-4, then the Company shall give written notice of such proposed filing to all of the Holders of Registrable Securities as soon as practicable but not less than ten (10) days before the anticipated filing date of such Registration Statement , which notice shall (A) describe the amount and type of securities to be included in such offering, the intended method(s) of distribution, and the name of the proposed managing Underwriter or Underwriters, if any, in such offering, and (B) offer to all of the Holders of Registrable Securities the opportunity to register the sale of such number of Registrable Securities as such Holders may request in writing within five (5) days after receipt of such written notice (in the case of an “overnight” or “bought” offering, such requests must be made by the Holders within one (1) Business Day after the delivery of any such notice by the Company) (such Registration a “Piggyback Registration”); provided, however, that if the Company has been advised by the managing Underwriter(s) that the inclusion of Registrable Securities for sale for the benefit of the Holders will have an adverse effect on the price, timing or distribution of the Class A Common Stock in the Underwritten Offering, then (A) if no Registrable Securities can be included in the Underwritten Offering in the opinion of the managing Underwriter(s), the Company shall not be required to offer such opportunity to the Holders or (B) if any Registrable Securities can be included in the Underwritten Offering in the opinion of the managing Underwriter(s), then the amount of Registrable Securities to be offered for the accounts of Holders shall be determined based on the provisions of Section 2.03(b). Subject to Section 2.03(b), the Company shall, in good faith, cause such Registrable Securities to be included in such Piggyback Registration and shall use its commercially reasonable efforts to cause the managing Underwriter or Underwriters of a proposed Underwritten Offering to permit the Registrable Securities requested by the Holders pursuant to this Section 2.03 to be included in a Piggyback Registration on the same terms and conditions as any similar securities of the Company included in such Registration and to permit the sale or other disposition of such Registrable Securities in accordance with the intended method(s) of distribution thereof. If no written request for inclusion from a Holder is received within the specified time, each such Holder shall have no further right to participate in such Underwritten Offering. All such Holders proposing to distribute their Registrable Securities through an Underwritten Offering under this Section 2.03 shall enter into an underwriting agreement in customary form with the Underwriter(s) selected for such Underwritten Offering by the Company.

9

(b) If the managing Underwriter or Underwriters in an Underwritten Offering that is to be a Piggyback Registration, in good faith, advises the Company and the Holders of Registrable Securities participating in the Piggyback Registration that the dollar amount or number of shares of Class A Common Stock that the Company desires to sell, taken together with (i) the shares of Class A Common Stock, if any, as to which Registration has been demanded pursuant to separate written contractual arrangements with persons or entities other than the Holders of Registrable Securities hereunder, (ii) the Registrable Securities as to which registration has been requested pursuant to Sections 2.02 and 2.03, and (iii) the shares of Class A Common Stock, if any, as to which Registration has been requested pursuant to separate written contractual piggy-back registration rights of other stockholders of the Company, exceeds the Maximum Number of Securities, then:

(i) If the Registration is undertaken for the Company’s account, the Company shall include in any such Registration (A) first, shares of Class A Common Stock or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; (B) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (A), pro rata to (1) the Registrable Securities of Holders exercising their rights to register their Registrable Securities pursuant to Sections 2.02 and 2.03 hereof, and (2) the Founder Registrable Securities of Founder Holders exercising their rights to register their Founder Registrable Securities pursuant to the Founder Registration Rights Agreement, which can be sold without exceeding the Maximum Number of Securities; and (C) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), shares of Class A Common Stock, if any, as to which Registration has been requested pursuant to written contractual piggy-back registration rights of other stockholders of the Company, which can be sold without exceeding the Maximum Number of Securities;

(ii) If the Registration is pursuant to a request by persons or entities other than the Holders of Registrable Securities, then the Company shall include in any such Registration (A) first, shares of Class A Common Stock or other equity securities, if any, of such requesting persons or entities, other than the Holders of Registrable Securities, which can be sold without exceeding the Maximum Number of Securities; (B) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (A), pro rata to (1) the Registrable Securities of Holders exercising their rights to register their Registrable Securities pursuant to Sections 2.02 and 2.03 hereof, and (2) the Founder Registrable Securities of Founder Holders exercising their rights to register their Founder Registrable Securities pursuant to the Founder Registration Rights Agreement, which can be sold without exceeding the Maximum Number of Securities; (C) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), shares of Class A Common Stock or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; and (D) fourth, to the

10

extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A), (B) and (C), shares of Class A Common Stock or other equity securities for the account of other persons or entities that the Company is obligated to register pursuant to separate written contractual arrangements with such persons or entities, which can be sold without exceeding the Maximum Number of Securities.

(c) Any Holder of Registrable Securities shall have the right to withdraw from a Piggyback Registration for any or no reason whatsoever upon written notification to the Company and the Underwriter or Underwriters (if any) of its intention to withdraw from such Piggyback Registration prior to the pricing of such Underwritten Offering. The Company (whether on its own good faith determination or as the result of a request for withdrawal by persons pursuant to separate written contractual obligations) may withdraw a Registration Statement filed with the Commission in connection with a Piggyback Registration at any time prior to the effectiveness of such Registration Statement. Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the Registration Expenses incurred in connection with the Piggyback Registration prior to its withdrawal under this Section 2.03.

(d) For purposes of clarity, any Registration effected pursuant to Section 2.03 hereof shall not be counted as a Registration effected under Section 2.02 hereof.

It is acknowledged by the Holders and the Company that the Holders shall bear all incremental selling expenses relating to the sale of Registrable Securities, such as Underwriters’ commissions and discounts, brokerage fees and, other than as set forth in the definition of “Registration Expenses,” all reasonable fees and expenses of any legal counsel representing the Holders.

13

Section 3.03 Requirements for Participation in Underwritten Offerings. No person may participate in any Underwritten Offering for equity securities of the Company hereunder unless such person (i) agrees to sell such person’s securities on the basis provided in the underwriting agreement for such Underwritten Offering and (ii) completes and executes all customary questionnaires, powers of attorney, indemnities, lock-up agreements, underwriting agreements and other customary documents as may be reasonably required under the terms of such underwriting agreement.

Section 3.04 Suspension of Sales; Adverse Disclosure.

(a) Upon receipt of written notice from the Company that a Registration Statement or Prospectus contains a Misstatement, each of the Holders shall forthwith discontinue disposition of Registrable Securities until it has received copies of a supplemented or amended Prospectus correcting the Misstatement (it being understood that the Company hereby covenants to prepare and file such supplement or amendment as soon as practicable after the time of such notice), or until it is advised in writing by the Company that the use of the Prospectus may be resumed (any such period, a “Suspension Period”).

(b) If the filing, initial effectiveness or continued use of a Registration Statement in respect of any Registration (including in connection with an Underwritten Offering) at any time would require the Company to make an Adverse Disclosure or would require the inclusion in such Registration Statement of financial statements that are unavailable to the Company for reasons beyond the Company’s control, then the Company may, upon giving prompt written notice to the Holders, delay the filing or initial effectiveness of, or suspend use of, such Registration Statement (including in connection with an Underwritten Offering) for the shortest period of time, but in no event more than thirty (30) days, determined in good faith by the Company to be necessary for such purpose (any such period, a “Blackout Period”). In the event the Company exercises its rights under the preceding sentence, the Holders agree to suspend, immediately upon their receipt of the notice referred to above, their use of the Prospectus relating to any Registration in connection with any sale or offer to sell Registrable Securities.

(c) The Company shall immediately notify the Holders of the expiration of any period during which it exercised its rights under this Section 3.04. Notwithstanding anything to the contrary in this Section 3.04, in no event shall any Suspension Period or any Blackout Period continue for more than ninety (90) days in the aggregate during any 365-day period.

Section 3.05 Reporting Obligations. As long as any Holder shall own Registrable Securities, the Company, at all times while it shall be a reporting company under the Exchange Act, covenants to file timely (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to Sections 13(a) or 15(d) of the Exchange Act and to promptly furnish the Holders with true and complete copies of all such filings (the delivery of which will be satisfied by the Company’s filing of such reports on the Commission’s EDGAR system). The Company further covenants that it shall take such further action as any Holder may reasonably request, all to the extent required from time to time to enable such Holder to sell shares of Class A Common Stock held by such Holder without registration under the Securities Act within the limitation of the

14

exemptions provided by Rule 144 promulgated under the Securities Act (or any successor rule promulgated thereafter by the Commission), including providing any legal opinions. Upon the request of any Holder, the Company shall deliver to such Holder a written certification of a duly authorized officer as to whether it has complied with such requirements.

ARTICLE IV.

INDEMNIFICATION AND CONTRIBUTION

Section 4.01 Indemnification.

(a) The Company agrees to indemnify, to the extent permitted by law, each Holder of Registrable Securities, its officers and directors and each person who controls such Holder (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and expenses (including attorneys’ fees) caused by any untrue or alleged untrue statement of material fact contained in any Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as the same are caused by or contained in any information furnished in writing to the Company by such Holder expressly for use therein. The Company shall indemnify the Underwriters, their officers and directors and each person who controls such Underwriters (within the meaning of the Securities Act) to the same extent as provided in the foregoing with respect to the indemnification of the Holder.

(b) In connection with any Registration Statement in which a Holder of Registrable Securities is participating, such Holder shall furnish to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such Registration Statement or Prospectus and, to the extent permitted by law, shall indemnify the Company, its directors and officers and agents and each person who controls the Company (within the meaning of the Securities Act) against any losses, claims, damages, liabilities and expenses (including without limitation reasonable attorneys’ fees) resulting from any untrue statement of material fact contained in the Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing by such Holder expressly for use therein; provided, however, that the obligation to indemnify shall be several, not joint and several, among such Holders of Registrable Securities, and the liability of each such Holder of Registrable Securities shall be in proportion to and limited to the net proceeds received by such Holder from the sale of Registrable Securities pursuant to such Registration Statement. The Holders of Registrable Securities shall indemnify the Underwriters, their officers, directors and each person who controls such Underwriters (within the meaning of the Securities Act) to the same extent as provided in the foregoing with respect to indemnification of the Company.

15

(c) Any person entitled to indemnification herein shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s right to indemnification hereunder to the extent such failure has not materially prejudiced the indemnifying party) and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent shall not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

(d) The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling person of such indemnified party and shall survive the transfer of securities. The Company and each Holder of Registrable Securities participating in an offering also agrees to make such provisions as are reasonably requested by any indemnified party for contribution to such party in the event the Company’s or such Holder’s indemnification is unavailable for any reason.

(e) If the indemnification provided under this Section 4.01 from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and expenses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities and expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and indemnified party 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, was made by, or relates to information supplied by, such indemnifying party or indemnified party, and the indemnifying party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action; provided, however, that the liability of any Holder under this Section 4.01(e) shall be limited to the amount of the net proceeds received by such Holder in such offering giving rise to such liability. The amount paid or payable by a party as a result of the losses or other liabilities referred to above shall be deemed to include, subject to the limitations set forth in Section 4.01(a), Section 4.01(b) and Section 4.01(c) above, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 4.01(e) were determined by pro rata allocation or by any

16

other method of allocation, which does not take account of the equitable considerations referred to in this Section 4.01(e). No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this Section 4.01(e) from any person who was not guilty of such fraudulent misrepresentation.

Section 5.04 Governing Law. NOTWITHSTANDING THE PLACE WHERE THIS AGREEMENT MAY BE EXECUTED BY ANY OF THE PARTIES HERETO, THE PARTIES EXPRESSLY AGREE THAT THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED UNDER THE LAWS OF THE STATE OF DELAWARE AS APPLIED TO AGREEMENTS AMONG DELAWARE RESIDENTS ENTERED INTO AND TO BE PERFORMED ENTIRELY WITHIN DELAWARE, WITHOUT REGARD TO THE CONFLICT OF LAW PROVISIONS OF SUCH JURISDICTION.

Section 5.05 Amendments and Modifications. Upon the written consent of the Company and the Holders of at least a majority in interest of the Registrable Securities at the time in question, compliance with any of the provisions, covenants and conditions set forth in this Agreement may be waived, or any of such provisions, covenants or conditions may be amended or modified; provided, however, that notwithstanding the foregoing, any amendment hereto or waiver hereof that adversely affects one Holder, solely in its capacity as a holder of the shares of capital stock of the Company, in a manner that is materially different from the other Holders (in such capacity) shall require the consent of the Holder so affected. No course of dealing between any Holder or the Company and any other party hereto or any failure or delay on the part of a Holder or the Company in exercising any rights or remedies under this Agreement shall operate as a waiver of any rights or remedies of any Holder or the Company. No single or partial exercise of any rights or remedies under this Agreement by a party shall operate as a waiver or preclude the exercise of any other rights or remedies hereunder or thereunder by such party.

Section 5.06 Other Registration Rights.

Further, the Company represents and warrants that this Agreement supersedes any other registration rights agreement or agreement with similar terms and conditions among the parties and in the event of a conflict between any such agreement or agreements and this Agreement, the terms of this Agreement shall prevail.
