2.                                       Provisions Relating to Common Stock.

(a)                                  Each share of Common Stock of the Corporation shall have identical rights and privileges in every respect.  Common Stock shall be subject to the express terms of the Preferred Stock and any series thereof.  Except as may otherwise be provided in this Amended and Restated Certificate of Incorporation, in a Preferred Stock Designation or by applicable law, the holders of shares of Common Stock shall be entitled to one vote for each such share upon all questions presented to the stockholders, the holders of shares of Common Stock shall have the exclusive right to vote for the election of directors and for all other purposes, and the holders of Preferred Stock shall not be entitled to vote at or receive notice of any meeting of stockholders.  Each holder of Common Stock shall be entitled to notice of any stockholders’ meeting in accordance with the bylaws of the Corporation (as in effect at the time in question) and applicable law on all matters put to a vote of the stockholders of the Corporation.

(b)                                  Notwithstanding the foregoing, except as otherwise required by law, holders of Common Stock, as such, shall not be entitled to vote on any amendment to this Amended and Restated Certificate of Incorporation (including any certificate of designations relating to any series of Preferred Stock) that relates solely to the terms of one or more outstanding series of Preferred Stock if the holders of such affected series are entitled, either separately or together with the holders of one or more other such series, to vote thereon pursuant to this Amended and Restated Certificate of Incorporation (including any certificate of designations relating to any series of Preferred Stock) or pursuant to the DGCL.

3

(d)                                  In the event of any voluntary or involuntary liquidation, dissolution or winding-up of the Corporation, after distribution in full of the preferential amounts, if any, to be distributed to the holders of shares of the Preferred Stock or any series thereof, the holders of shares of Common Stock shall be entitled to receive all of the remaining assets of the Corporation available for distribution to its stockholders, ratably in proportion to the number of shares of Common Stock held by them.  A liquidation, dissolution or winding-up of the Corporation, as such terms are used in this paragraph (d), shall not be deemed to be occasioned by or to include any consolidation or merger of the Corporation with or into any other corporation or corporations or other entity or a sale, lease, exchange or conveyance of all or a part of the assets of the Corporation.

(e)                                   The number of authorized shares of Common Stock or Preferred Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority in voting power of the outstanding shares of stock of the Corporation entitled to vote thereon irrespective of the provisions of Section 242(b)(2) of the DGCL (or any successor provision thereto), and no vote of the holders of either the Common Stock or the Preferred Stock voting separately as a class shall be required therefor.

FIFTH:  The business and affairs of the Corporation shall be managed by or under the direction of the Board of Directors. The directors, other than those who may be elected by the holders of any series of Preferred Stock specified in the related Preferred Stock Designation, shall be divided, with respect to the time for which they severally hold office, into three classes, as nearly equal in number as is reasonably possible, with the initial term of office of the first class to expire at the 2014 annual meeting (the “ Class I Directors ”), the initial term of office of the second class to expire at the 2015 annual meeting (the “ Class II Directors ”), and the initial term of office of the third class to expire at the 2016 annual meeting (the “ Class III Directors ”), with each director to hold office until his or her successor shall have been duly elected and qualified. At each annual meeting of stockholders directors elected to succeed those directors whose terms then expire shall be elected for a term of office to expire at the third succeeding annual meeting of stockholders after their election, with each director to hold office until his or her successor shall have been duly elected and qualified.  The Board of Directors is authorized to assign members of the Board of Directors already in office to Class I, Class II or Class III at the time such classification becomes effective.

Subject to the rights of holders of any series of Preferred Stock, any newly created directorship that results from an increase in the number of directors or any vacancy on the Board of Directors that results from the death, disability, resignation, disqualification or removal of any director or from any other cause shall be filled solely by the affirmative vote of a majority of the total number of directors then in office, even if less than a quorum, or by a sole remaining director and shall not be filled by the stockholders.  Any director elected to fill a vacancy not resulting from an increase in the number of directors shall hold office for the remaining term of his or her predecessor.  No decrease in the number of authorized directors constituting the Board of Directors shall shorten the term of any incumbent director.

Until the first date on which Antero Resources Investment LLC, Warburg Pincus LLC, Yorktown Partners LLC and Trilantic Capital Partners and their Affiliates (as such term is defined in Rule 12b-2 promulgated under the Securities Exchange Act of 1934, as amended)

From and after the Trigger Date and subject to the rights of the holders of shares of any series of Preferred Stock, if any, to elect additional directors pursuant to this Amended and Restated Certificate of Incorporation (including any Preferred Stock Designation thereunder), any director may be removed only for cause, upon the affirmative vote of the holders of at least a majority of the outstanding shares of stock of the Corporation entitled to vote generally for the election of directors, acting at a meeting of the stockholders or by written consent (if permitted) in accordance with the DGCL, this Amended and Restated Certificate of Incorporation and the bylaws of the Corporation.

Subject to the rights of the holders of any series of Preferred Stock to elect directors under specified circumstances, if any, the number of directors shall be fixed from time to time exclusively pursuant to a resolution adopted by a majority of the Board of Directors.  Unless and except to the extent that the bylaws of the Corporation so provide, the election of directors need not be by written ballot.

SIXTH:  Prior to the Trigger Date, any action required or permitted to be taken at any annual meeting or special meeting of the stockholders of the Corporation may be taken without a meeting, without prior notice and without a vote of stockholders, if a consent or consents in writing, setting forth the action so taken, is or are signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted. On and after the Trigger Date, subject to the rights of holders of any series of Preferred Stock with respect to such series of Preferred Stock, any action required or permitted to be taken by the stockholders of the Corporation must be taken at a duly held annual or special meeting of stockholders and may not be taken by any consent in writing of such stockholders.

SEVENTH:  Special meetings of stockholders of the Corporation may be called only by the Chief Executive Officer, the Chairman of the Board or the Board of Directors pursuant to a resolution adopted by a majority of the total number of directors which the Corporation would have if there were no vacancies; provided , however , that prior to the Trigger Date, special meetings of the stockholders of the Corporation may also be called by the Secretary of the Corporation at the request of the holders of record of a majority of the outstanding shares of Common Stock.  From and after the Trigger Date, and subject to the rights of holders of any series of Preferred Stock, the stockholders of the Corporation do not have the power to call a special meeting of stockholders of the Corporation.

EIGHTH:  In furtherance of, and not in limitation of, the powers conferred by the laws of the State of Delaware, the Board of Directors is expressly authorized to adopt, amend or repeal

5

the bylaws of the Corporation; provided , however , that, the provisions of this Article Eighth notwithstanding, the bylaws of the Corporation shall not be adopted, altered, amended or repealed by the stockholders of the Corporation (i) prior to the Trigger Date, except by the vote of holders of not less than 50% in voting power of the then-outstanding shares of stock entitled to vote thereon, voting together as a single class, or (ii) after the Trigger Date, except by the vote of holders of not less than 66 2 / 3 % in voting power of the then-outstanding shares of stock entitled to vote thereon, voting together as a single class.

NINTH:  No director of the Corporation shall be liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except to the extent such exemption from liability or limitation thereof is not permitted under the DGCL as it now exists.  In addition to the circumstances in which a director of the Corporation is not personally liable as set forth in the preceding sentence, a director of the Corporation shall not be liable to the fullest extent permitted by any amendment to the DGCL hereafter enacted that further limits the liability of a director.

Any amendment, repeal or modification of this Article Ninth shall be prospective only and shall not affect any limitation on liability of a director for acts or omissions occurring prior to the date of such amendment, repeal or modification.

TENTH:  The Sponsor Group and their Affiliates (other than the Corporation and its subsidiaries), agents, shareholders, members, partners, officers, directors and employees, including any director or officer of the Corporation who is also a shareholder, member, partner, officer, director, or employee of any member of the Sponsor Group (each, a “ Specified Party ”), have participated (directly or indirectly) in and may, and shall have no duty not to, continue to (x) participate (directly or indirectly) in venture capital and other direct investments in corporations, joint ventures, limited liability companies and other entities conducting business of any kind, nature or description (“ Other Investments ”) and (y) have interests in, participate with, aid and maintain seats on the boards of directors or similar governing bodies of Other Investments, in each case that may, are or will be competitive with the business of the Corporation and its subsidiaries or in the same or similar lines of business as the Corporation and its subsidiaries, or that could be suitable for the Corporation or its subsidiaries. To the fullest extent permitted by applicable law, the Corporation, on behalf of itself and its subsidiaries, renounces any interest or expectancy of the Corporation and its subsidiaries in, or in being offered an opportunity to participate in, any such Other Investment or any business opportunities for such Other Investments that are from time to time presented to any Specified Party or are business opportunities in which a Specified Party participates or desires to participate, even if the Other Investment or business opportunity is one that the Corporation or its subsidiaries might reasonably be deemed to have pursued or had the ability or desire to pursue if granted the opportunity to do so, and each such Specified Party shall have no duty to communicate or offer any such Other Investment or business opportunity to the Corporation and, to the fullest extent permitted by applicable law, shall not be liable to the Corporation or any of its subsidiaries or any stockholder, including for breach of any fiduciary or other duty, as a director or officer or controlling stockholder or otherwise, and the Corporation shall indemnify each Specified Person against any claim that such Specified Person is liable to the Corporation or its stockholders for breach of any fiduciary duty, by reason of the fact that such Specified Party (i) participates in any such Other Investment or pursues or acquires any such business opportunity, (ii) directs any such

6

business opportunity to another person or (iii) fails to present any such Other Investment or business opportunity, or information regarding such Other Investment or business opportunity, to the Corporation or its subsidiaries, unless, in the case of a Specified Party who is a director of the Corporation, any such business opportunity is expressly offered to such Specified Party in writing solely in his or her capacity as a director of the Corporation.

Neither the amendment nor repeal of this Article Tenth, nor the adoption of any provision of this Amended and Restated Certificate of Incorporation or the bylaws of the Corporation, nor, to the fullest extent permitted by Delaware law, any modification of law, shall eliminate, reduce or otherwise adversely affect any right or protection of any person granted pursuant hereto existing at, or arising out of or related to any event, act or omission that occurred prior to, the time of such amendment, repeal, adoption or modification (regardless of when any proceeding (or part thereof) relating to such event, act or omission arises or is first threatened, commenced or completed).

If any provision or provisions of this Article Tenth shall be held to be invalid, illegal or unenforceable as applied to any circumstance for any reason whatsoever: (a) the validity, legality and enforceability of such provisions in any other circumstance and of the remaining provisions of this Article Tenth (including, without limitation, each portion of any paragraph of this Article Tenth containing any such provision held to be invalid, illegal or unenforceable that is not itself  held to be invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby and (b) to the fullest extent possible, the provisions of this Article Tenth (including, without limitation, each such portion of any paragraph of this Article Tenth containing any such provision held to be invalid, illegal or unenforceable) shall be construed so as to permit the Corporation to protect its directors, officers, employees and agents from personal liability in respect of their good faith service to or for the benefit of the Corporation to the fullest extent permitted by law.

This Article Tenth shall not limit any protections or defenses available to, or indemnification or advancement rights of, any director or officer of the Corporation under this Amended and Restated Certificate of Incorporation, the bylaws of the Corporation or applicable law. Any person or entity purchasing or otherwise acquiring any interest in any securities of the Corporation shall be deemed to have notice of and to have consented to the provisions of this Article Tenth.

SECTION 2.3.                                           Record Date .

(A)                                                        In order that the Corporation may determine the stockholders entitled to notice of any meeting of stockholders or any adjournment thereof, the Board may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board, and which record date shall, unless otherwise required by law, not be more than sixty (60) nor less than ten (10) days before the date of such meeting.  If the Board so fixes a date, such date shall also be the record date for determining the stockholders entitled to vote at such meeting unless the Board determines, at the time it fixes such record date, that a later date on or before the date of the meeting shall be the date for making such determination.  If no record date is fixed by the Board, the record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be at the close of business on the day next preceding the day on which notice is given, or, if notice is waived, at the close of business on the day next preceding the day on which the meeting is held.  A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting; provided, however , that the Board may fix a new record date for determination of stockholders entitled to vote at the adjourned meeting, and in such case shall also fix as the record date for stockholders entitled to notice of such adjourned meeting the same date as that fixed for determination of stockholders entitled to vote in accordance herewith at the adjourned meeting.

(B)                                                        In order that the Corporation may determine the stockholders entitled to receive payment of any dividend or other distribution or allotment of any rights, or entitled to exercise any rights in respect of any change, conversion or exchange of stock or for the purpose of any other lawful action, the Board may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted, and which record date shall not be more than sixty (60) days prior to such action.  If no such record date is fixed, the record date for determining stockholders for any such purpose shall be at the close of business on the day on which the Board adopts the resolution relating thereto.

(C)                                                        Unless otherwise restricted by the Amended and Restated Certificate of Incorporation of the Corporation, as it may be amended from time to time (the “ Certificate of Incorporation ”), in order that the Corporation may determine the stockholders entitled to express consent to corporate action in writing without a meeting, the Board may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board, and which record date shall not be more than ten (10) days after the date upon which the resolution fixing the record date is adopted by the Board.  If no record date for determining stockholders entitled to express consent to corporate action in writing without a meeting is fixed by the Board, (i) when no prior action of the Board is required by law, the record date for such purpose shall be the first date on which a signed written consent setting forth the action taken or proposed to be taken is delivered to the Corporation in accordance with

applicable law, and (ii) if prior action by the Board is required by law, the record date for such purpose shall be at the close of business on the day on which the Board adopts the resolution taking such prior action.

SECTION 2.5.                                           Place of Meeting .  The Board, the Chairman of the Board or the Chief Executive Officer, as the case may be, may designate the place of meeting for any annual meeting or for any special meeting of the stockholders called by the stockholders (prior to the Trigger Date) or by the Board, the Chairman of the Board or the Chief Executive Officer.  If no designation is so made, the place of meeting shall be the principal executive offices of the Corporation.  The Board, acting in its sole discretion, may establish guidelines and procedures in accordance with applicable provisions of the Delaware General Corporation Law and any other applicable law for the participation by stockholders and proxyholders in a meeting of stockholders by means of remote communications, and may determine that any meeting of stockholders will not be held at any place but will be held solely by means of remote communication.  Stockholders and proxyholders complying with such procedures and guidelines and otherwise entitled to vote at a meeting of stockholders shall be deemed present in person and entitled to vote at a meeting of stockholders, whether such meeting is to be held at a designated place or solely by means of remote communication.

SECTION 2.6.                                           Notice of Meeting .  Written or printed notice, stating the place, if any, day and hour of the meeting and the purpose or purposes for which the meeting is called, shall be given not less than 10 days nor more than 60 days before the date of the meeting, in a manner pursuant to Section 7.8 hereof, to each stockholder of record entitled to vote at such meeting.  The notice shall specify (i) the record date for determining the stockholders entitled to vote at the meeting (if such date is different from the record date for stockholders entitled to notice of the meeting), (ii) the place, if any, date and time of such meeting, (iii) the means of remote

3

communications, if any, by which stockholders and proxyholders may be deemed to be present in person and vote at such meeting, (iv) in the case of a special meeting, the purpose or purposes for which such meeting is called and (v) such other information as may be required by law or as may be deemed appropriate by the Board, the Chairman of the Board, the Chief Executive Officer or the Secretary of the Corporation.  If the stockholder list referred to in Section 2.4 of these Bylaws is made accessible on an electronic network, the notice of meeting must indicate how the stockholder list can be accessed.  If the meeting of stockholders is to be held solely by means of electronic communications, the notice of meeting must provide the information required to access such stockholder list during the meeting.  If mailed, such notice shall be deemed to be delivered when deposited in the United States mail with postage thereon prepaid, addressed to the stockholder at his address as it appears on the stock transfer books of the Corporation.  The Corporation may provide stockholders with notice of a meeting by electronic transmission provided such stockholders have consented to receiving electronic notice in accordance with the Delaware General Corporation Law.  Such further notice shall be given as may be required by law.  Only such business shall be conducted at a special meeting of stockholders as shall have been brought before the meeting pursuant to the notice of meeting.  Meetings may be held without notice if all stockholders entitled to vote are present, or if notice is waived by those not present in accordance with Section 7.4 of these Bylaws.

SECTION 2.7.                                           Quorum and Adjournment of Meetings .

(A)                                                        Except as otherwise provided by law or by the Certificate of Incorporation, the holders of a majority of the outstanding shares of stock of the Corporation entitled to vote at the meeting (the “ Voting Stock ”), represented in person or by proxy, shall constitute a quorum at a meeting of stockholders, except that when specified business is to be voted on by a class or series of stock voting as a class, the holders of a majority of the shares of such class or series shall constitute a quorum of such class or series for the transaction of such business.  The chairman of the meeting or a majority of the shares so represented may adjourn the meeting from time to time, whether or not there is such a quorum.

(B)                                                        Any meeting of stockholders, annual or special, may adjourn from time to time to reconvene at the same or some other place, and notice need not be given of any such adjourned meeting if the time and place thereof are announced at the meeting at which the adjournment is taken.  At the adjourned meeting, the Corporation may transact any business which might have been transacted at the original meeting.  If the adjournment is for more than thirty (30) days, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting.  The stockholders present at a duly called meeting at which a quorum is present may continue to transact business until adjournment, notwithstanding the withdrawal of enough stockholders to leave less than a quorum.

SECTION 2.8.                                           Proxies .  At all meetings of stockholders, a stockholder may vote by proxy executed in writing (or in such other manner prescribed by the Delaware General Corporation Law) by the stockholder, or by his duly authorized attorney-in-fact.  Any copy, facsimile transmission or other reliable reproduction of the writing or transmission created pursuant to this section may be substituted or used in lieu of the original writing or transmission for any and all purposes for which the original writing or transmission could be used, provided that such copy, facsimile transmission or other reproduction shall be a complete reproduction of

4

the entire original writing or transmission.  No proxy may be voted or acted upon after the expiration of three (3) years from the date of such proxy, unless such proxy provides for a longer period.  Every proxy is revocable at the pleasure of the stockholder executing it unless the proxy states that it is irrevocable and applicable law makes it irrevocable.  A stockholder may revoke any proxy that is not irrevocable by attending the meeting and voting in person or by filing an instrument in writing revoking the proxy or by filing another duly executed proxy bearing a later date with the Secretary of the Corporation.

SECTION 2.9.                                           Notice of Stockholder Business and Nominations .

STOCK CERTIFICATES AND TRANSFERS

SECTION 6.1.                                           Stock Certificates and Transfers .  The interest of each stockholder of the Corporation shall be evidenced by certificates for shares of stock in such form as the appropriate officers of the Corporation may from time to time prescribe, provided that the Board may provide by resolution or resolutions that some or all of any or all classes or series of its stock may be uncertificated or electronic shares.  The shares of the stock of the Corporation shall

16

be entered in the books of the Corporation as they are issued and shall exhibit the holder’s name and number of shares.  Subject to the provisions of the Certificate of Incorporation, the shares of the stock of the Corporation shall be transferred on the books of the Corporation, which may be maintained by a third-party registrar or transfer agent, by the holder thereof in person or by his attorney, upon surrender for cancellation of certificates for at least the same number of shares, with an assignment and power of transfer endorsed thereon or attached thereto, duly executed, with such proof of the authenticity of the signature as the Corporation or its agents may reasonably require or upon receipt of proper transfer instructions from the registered holder of uncertificated shares and upon compliance with appropriate procedures for transferring shares in uncertificated form, at which time the Corporation shall issue a new certificate to the person entitled thereto (if the stock is then represented by certificates), cancel the old certificate and record the transaction upon its books.

Each certificated share of stock shall be signed, countersigned and registered in such manner as the Board may by resolution prescribe, which resolution may permit all or any of the signatures on such certificates to be in facsimile.  In case any officer, transfer agent or registrar who has signed or whose facsimile signature has been placed upon a certificate has ceased to be such officer, transfer agent or registrar before such certificate is issued, it may be issued by the Corporation with the same effect as if he were such officer, transfer agent or registrar at the date of issue.

SECTION 6.2.                                           Lost, Stolen or Destroyed Certificates .  No certificate for shares or uncertificated shares of stock in the Corporation shall be issued in place of any certificate alleged to have been lost, destroyed or stolen, except on production of such evidence of such loss, destruction or theft and on delivery to the Corporation of a bond of indemnity in such amount, upon such terms and secured by such surety, as the Board or any financial officer may in its or his discretion require.

SECTION 6.3.                                           Ownership of Shares .  The Corporation shall be entitled to treat the holder of record of any share or shares of stock of the Corporation as the holder in fact thereof and, accordingly, shall not be bound to recognize any equitable or other claim to or interest in such share or shares on the part of any other person, whether or not it shall have express or other notice thereof, except as otherwise provided by the laws of the State of Delaware.

SECTION 6.4.                                           Regulations Regarding Certificates .  The Board shall have the power and authority to make all such rules and regulations as they may deem expedient concerning the issue, transfer and registration or the replacement of certificates for shares of stock of the Corporation.  The Corporation may enter into additional agreements with stockholders to restrict the transfer of stock of the Corporation in any manner not prohibited by the Delaware General Corporation Law.

(D)                                The rights conferred on any Covered Person by this Section 7.6 shall not be exclusive of any other rights which such Covered Person may have or hereafter acquire under any statute, provision of the Certificate of Incorporation, these Bylaws, agreement, vote of stockholders or disinterested directors or otherwise.

(E)                                 This Section 7.6 shall not limit the right of the Corporation, to the extent and in the manner permitted by law, to indemnify and to advance expenses to persons other than Covered Persons when and as authorized by appropriate corporate action.
