Section 6.                                            Additional Indemnification .  Notwithstanding any limitation in Section 2 , Section 3 or Section 4 hereof (but subject to Section 7 ), the Company shall indemnify Indemnitee to the fullest extent permitted by applicable law if Indemnitee is a party to or threatened to be made a party to any Proceeding (including a Proceeding by or in the right of the Company to procure a judgment in its favor) against all Liabilities and Expenses suffered or reasonably incurred by Indemnitee in connection with such Proceeding. For purposes of this Section 6, the meaning of “to the fullest extent permitted by applicable law” shall include but not be limited to:

(a)                                  the fullest extent permitted by the provision of the DGCL that authorizes, permits or contemplates additional indemnification by agreement, or the corresponding provision of any amendment to or replacement of the DGCL; and

(b)                                  the fullest extent authorized or permitted by any amendments to or replacements of the DGCL adopted after the date of this Agreement that increase the extent to which a corporation may indemnify its officers and directors.

Section 7.                                            Exclusions .  Notwithstanding any provision in this Agreement, the Company shall not be obligated under this Agreement to indemnify or hold harmless Indemnitee:

(b)                                  for an accounting of profits made from the purchase and sale (or sale and purchase) by Indemnitee of securities of the Company within the meaning of Section 16(b) of the Exchange Act or similar provisions of state statutory law or common law;

(c)                                   except for any proceeding by Indemnitee to enforce its rights under this Agreement, as provided in Section 12(d)  of this Agreement, in connection with any Proceeding (or any part of any Proceeding) initiated by Indemnitee, including any Proceeding (or any part of any Proceeding) initiated by Indemnitee against the Company

5

or its directors, officers, employees or other indemnitees, unless (i) the Board authorized the Proceeding (or any part of any Proceeding) prior to its initiation or (ii) the Company provides the indemnification, in its sole discretion, pursuant to the powers vested in the Company under applicable law; or

(d)                                  if it is ultimately determined, by final judicial decision of a court of competent jurisdiction from which there is no further right to appeal, that such indemnification is not lawful.

Section 8.                                            Advancement .  Following notification to the Company under Section 9(a)  of a Proceeding with respect to which Indemnitee intends to seek payment under this Agreement, in accordance with the pre-existing requirements of the Certificate of Incorporation and the Bylaws, and notwithstanding any provision of this Agreement to the contrary (but subject to Section 7 ), the Company shall advance, to the extent not prohibited by applicable law, the Expenses reasonably incurred by Indemnitee in connection with any Proceeding, and such advancement shall be made within twenty (20) days after the receipt by the Company of a statement or statements requesting such advances from time to time, whether prior to or after final disposition of any Proceeding.  Advances shall be unsecured and interest free.  Advances shall be made without regard to Indemnitee’s ability to repay the Expenses and without regard to Indemnitee’s ultimate entitlement to indemnification under the other provisions of this Agreement.  Advances shall include any and all Expenses reasonably incurred pursuing an action to enforce this right of advancement, including Expenses incurred preparing and forwarding statements to the Company to support the advances claimed, in addition to those Expenses incurred in connection with any Proceeding by Indemnitee seeking an adjudication or award in arbitration pursuant to Section 12(d)  of this Agreement.  With respect to any Proceeding with respect to which Indemnitee is entitled to advancement of Expenses, Indemnitee shall also be entitled to exercise the rights set forth in Section 9(b) .  Indemnitee shall qualify for advances upon the execution and delivery to the Company of this Agreement, which shall constitute an undertaking providing that Indemnitee undertakes to repay the amounts advanced to the extent that it is ultimately determined, by final judicial decision of a court of competent jurisdiction from which there is no further right to appeal, that Indemnitee is not entitled to be indemnified for such Expenses by the Company as provided by this Agreement.  This Section 8 shall not apply to any claim made by Indemnitee for which indemnity is excluded pursuant to paragraph (c)  or (d)  of Section 7 hereof.

Section 9.                                            Procedure for Notification and Defense of Claim .

(a)                                  Indemnitee shall promptly notify the Company in writing of any Proceeding with respect to which Indemnitee intends to seek payment hereunder following the receipt by Indemnitee of written notice thereof.  The written notification to the Company shall include a description of the nature of the Proceeding and the facts underlying the Proceeding.  To obtain indemnification under this Agreement, Indemnitee shall submit to the Company a written request, including therein or therewith such documentation and information as is reasonably available to Indemnitee and is reasonably necessary to determine whether and to what extent Indemnitee is entitled to indemnification following the final disposition of such Proceeding (the date of such request, the “ Submission Date ”).  Any delay or failure by Indemnitee to notify the Company hereunder will not relieve the Company from any liability which it may have to Indemnitee hereunder or otherwise than

6

under this Agreement, and any delay or failure in so notifying the Company shall not constitute a waiver by Indemnitee of any rights under this Agreement.  The Secretary of the Company shall, promptly upon receipt of such a request for indemnification, advise the Board in writing that Indemnitee has requested indemnification.

(b)                                  In the event Indemnitee is entitled to indemnification and/or advancement with respect to any Proceeding, Indemnitee may, at Indemnitee’s option, (i) retain counsel selected by Indemnitee and approved by the Company to defend Indemnitee in such Proceeding, at the sole expense of the Company (which approval shall not be unreasonably withheld, conditioned or delayed), or (ii) have the Company assume the defense of Indemnitee in such Proceeding, in which case the Company shall assume the defense of such Proceeding with counsel selected by the Company and approved by Indemnitee (which approval shall not be unreasonably withheld, conditioned or delayed) within ten (10) days of the Company’s receipt of written notice of Indemnitee’s election to cause the Company to do so.  If the Company is required to assume the defense of any such Proceeding, it shall engage legal counsel for such defense, and the Company shall be solely responsible for all fees and expenses of such legal counsel and otherwise of such defense.  Such legal counsel may represent both Indemnitee and the Company (and any other party or parties entitled to be indemnified by the Company with respect to such matter) unless, in the reasonable opinion of legal counsel to Indemnitee, there is a conflict of interest between Indemnitee and the Company (or any other such party or parties) or there are legal defenses available to Indemnitee that are not available to the Company (or any such other party or parties).  Notwithstanding either party’s assumption of responsibility for defense of a Proceeding, each party shall have the right to engage separate counsel at its own expense.  The party having responsibility for defense of a Proceeding shall provide the other party and its counsel with all copies of pleadings and material correspondence relating to the Proceeding.  Indemnitee and the Company shall reasonably cooperate in the defense of any Proceeding with respect to which indemnification and/or advancement is sought hereunder, regardless of whether the Company or Indemnitee assumes the defense thereof.  Indemnitee may not settle or compromise any Proceeding without the prior written consent of the Company, which consent shall not be unreasonably withheld, conditioned or delayed.  The Company may not settle or compromise any Proceeding without the prior written consent of Indemnitee, which consent shall not be unreasonably withheld, conditioned or delayed.

Section 10.                                     Procedure Upon Application for Indemnification .

(a)                                  Upon written request by Indemnitee for indemnification pursuant to Section 9(a)  hereof, if any determination by the Company is required by applicable law with respect to Indemnitee’s entitlement thereto, such determination shall be made (i) if Indemnitee shall request such determination be made by Independent Counsel, by Independent Counsel, and (ii) in all other circumstances, (A) by a majority vote of the Disinterested Directors, even though less than a quorum of the Board, (B) by a committee of Disinterested Directors designated by a majority vote of the Disinterested Directors, even though less than a quorum of the Board, (C) if there are no such Disinterested Directors or, if such Disinterested Directors so direct, by Independent Counsel in a written opinion to the Board, a copy of which shall be delivered to Indemnitee, or (D) if so directed

7

by the Board, by the stockholders of the Company; and, if it is so determined that Indemnitee is entitled to indemnification, payment to Indemnitee shall be made promptly, and in any event within thirty (30) days after the Submission Date (subject to any permitted extension with respect to such determination pursuant to Section 11(b)  hereof).  Indemnitee shall cooperate with the person, persons or entity making such determination with respect to Indemnitee’s entitlement to indemnification, including providing to such person, persons or entity upon reasonable advance request any documentation or information which is not privileged or otherwise protected from disclosure and which is reasonably available to Indemnitee and reasonably necessary to such determination.  Any Expenses incurred by Indemnitee in so cooperating with the person, persons or entity making such determination shall be borne by the Company (irrespective of the determination as to Indemnitee’s entitlement to indemnification) and the Company hereby indemnifies and agrees to hold Indemnitee harmless therefrom.  The Company will not deny any written request for indemnification hereunder made in good faith by Indemnitee unless a determination as to Indemnitee’s entitlement to such indemnification described in this Section 10(a)  has been made.  The Company agrees to pay the reasonable fees and expenses of the Independent Counsel referred to above and to fully indemnify such counsel against any and all Liabilities and Expenses arising out of or relating to this Agreement or its engagement pursuant hereto.

(b)                                  In the event the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to Section 10(a)  hereof, the Independent Counsel shall be selected by the Company within ten (10) days of the Submission Date (the cost of such Independent Counsel to be paid by the Company) and the Company shall give written notice to Indemnitee advising it of the identity of the Independent Counsel so selected; provided , however , that if a change in control has occurred and results in individuals who were directors prior to the circumstances giving rise to the change in control ceasing for any reason to constitute a majority of the Board, such Independent Counsel shall be selected by the Indemnitee within ten (10) days of the Submission Date (the cost of such Independent Counsel to be paid by the Company) and Indemnitee shall give written notice to the Company advising it of the identity of the Independent Counsel so selected.  In either case, Indemnitee or the Company, as applicable, may, within ten (10) days after such written notice of selection shall have been given, deliver to the other a written objection to such selection.  Such objection may be asserted only on the ground that the Independent Counsel selected does not meet the requirements of “Independent Counsel” as defined in this Agreement.  If such written objection is made and substantiated, the Independent Counsel selected shall not serve as Independent Counsel unless and until Indemnitee or the Company, as applicable, withdraws the objection or a court has determined that such objection is without merit.  Absent a timely objection, the person so selected shall act as Independent Counsel.  If no Independent Counsel shall have been selected and not objected to before the later of (i) thirty (30) days after the later of the Submission Date and (ii) ten (10) days after the final disposition of the Proceeding, each of the Company and Indemnitee shall select a law firm or member of a law firm meeting the qualifications to serve as Independent Counsel, and such law firms or members of law firms shall select the Independent Counsel.  Upon the due commencement of any judicial proceeding or arbitration pursuant to Section 12(a)  of this Agreement, Independent Counsel shall be

8

discharged and relieved of any further responsibility in such capacity (subject to the applicable standards of professional conduct then prevailing).

Section 11.                                     Presumptions and Effect of Certain Proceedings .

(a)                                  In making a determination with respect to entitlement to indemnification hereunder, the person, persons or entity making such determination shall, to the fullest extent not prohibited by applicable law, presume that Indemnitee is entitled to indemnification under this Agreement if Indemnitee has submitted a request for indemnification in accordance with Section 9(a)  of this Agreement, and the Company shall, to the fullest extent not prohibited by applicable law, have the burden of proof to overcome that presumption in connection with the making by any person, persons or entity of any determination contrary to that presumption.  Neither the failure of the Company (including by its directors or independent legal counsel) to have made a determination prior to the commencement of any action pursuant to this Agreement that indemnification is proper in the circumstances because Indemnitee has met the applicable standard of conduct, nor an actual determination by the Company (including by its directors or independent legal counsel) that Indemnitee has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that Indemnitee has not met the applicable standard of conduct.

(b)                                  Subject to Section 12(e)  hereof, if the person, persons or entity empowered or selected under Section 10 of this Agreement to determine whether Indemnitee is entitled to indemnification shall not have made a determination within thirty (30) days after the Submission Date, the requisite determination of entitlement to indemnification shall, to the fullest extent not prohibited by applicable law, be deemed to have been made and Indemnitee shall be entitled to such indemnification, absent actual fraud in the request for indemnification; provided , however , that such 30-day period may be extended for a reasonable time, not to exceed an additional thirty (30) days, if (i) the determination is to be made by Independent Counsel and either the Company or Indemnitee, as applicable, objects to the selection of Independent Counsel and (ii) the Independent Counsel ultimately selected requires such additional time for the obtaining or evaluating of documentation or information relating thereto; provided further that such 30-day period may also be extended for a reasonable time, not to exceed an additional sixty (60) days, if the determination of entitlement to indemnification is to be made by the stockholders of the Company.

(c)                                   The termination of any Proceeding or of any claim, issue or matter therein, by judgment, order, settlement or conviction, or upon a plea of nolo contendere or its equivalent, shall not (except as otherwise expressly provided in this Agreement) adversely affect the right of Indemnitee to indemnification or create a presumption that Indemnitee did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the Company or, with respect to any criminal Proceeding, that Indemnitee had reasonable cause to believe that Indemnitee’s conduct was unlawful.

(d)                                  Reliance as Safe Harbor .  For purposes of any determination of good faith, Indemnitee shall be deemed to have acted in good faith if Indemnitee’s action or inaction is based on the records or books of account of the Enterprise, including financial

9

statements, or on information supplied to Indemnitee by the officers of the Enterprise in the course of their duties, or on the advice of legal counsel for the Enterprise or on information or records given or reports made to the Enterprise by an independent certified public accountant or by an appraiser or other expert selected with the reasonable care by the Enterprise.  The provisions of this Section 11(d)  shall not be deemed to be exclusive or to limit in any way the other circumstances in which Indemnitee may be deemed to have met the applicable standard of conduct set forth in this Agreement.

(e)                                   Actions of Others .  The knowledge or actions, or failure to act, of any director, officer, agent or employee of the Enterprise shall not be imputed to Indemnitee for purposes of determining the right to indemnification under this Agreement.

Section 12.                                     Remedies of Indemnitee .

(a)                                  Subject to Section 12(e)  hereof, in the event that (i) a determination is made pursuant to Section 10 of this Agreement that Indemnitee is not entitled to indemnification under this Agreement, (ii) advancement is not timely made pursuant to Section 8 of this Agreement, (iii) no determination of entitlement to indemnification shall have been made pursuant to Section 10(a)  of this Agreement within thirty (30) days after the Submission Date (subject to any permitted extension with respect to such determination pursuant to Section 11(a)  hereof), (iv) payment of indemnification is not made pursuant to Section 4 or Section 5 or the last sentence of Section 10(a)  of this Agreement within ten (10) days after receipt by the Company of a written request therefor, (v) payment of indemnification pursuant to Section 2 , Section 3 or Section 6 of this Agreement is not made within ten (10) days after a determination has been made that Indemnitee is entitled to indemnification, or (vi) in the event that the Company or any other Person takes or threatens to take any action to declare this Agreement void or unenforceable, or institutes any litigation or other action or proceeding designed to deny, or to recover from, Indemnitee the benefits provided or intended to be provided to Indemnitee hereunder, Indemnitee shall be entitled to an adjudication, by the Delaware Court of Chancery, of Indemnitee’s entitlement to such indemnification or advancement.  Alternatively, Indemnitee, at Indemnitee’s option, may seek an award in arbitration to be conducted by a single arbitrator pursuant to the Commercial Arbitration Rules of the American Arbitration Association.  The Company shall not oppose Indemnitee’s right to seek any such adjudication or award in arbitration.

(b)                                  In the event that a determination shall have been made pursuant to Section 10(a)  of this Agreement that Indemnitee is not entitled to indemnification, any judicial proceeding or arbitration commenced pursuant to this Section 12 shall be conducted in all respects as a de novo trial, or arbitration, on the merits and Indemnitee shall not be prejudiced by reason of that adverse determination.  In any judicial proceeding or arbitration commenced pursuant to this Section 12 the Company shall have the burden of proving Indemnitee is not entitled to indemnification or advancement, as the case may be.

(c)                                   If a determination shall have been made pursuant to Section 10 of this Agreement that Indemnitee is entitled to indemnification, the Company shall be bound by

10

such determination in any judicial proceeding or arbitration commenced pursuant to this Section 12 , absent a prohibition of such indemnification under applicable law.

(d)                                  The Company shall, to the fullest extent not prohibited by applicable law, be precluded from asserting in any judicial proceeding or arbitration commenced pursuant to this Section 12 that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court or before any such arbitrator that the Company is bound by all the provisions of this Agreement.  It is the intent of the Company that Indemnitee not be required to incur Expenses associated with the interpretation, enforcement or defense of Indemnitee’s rights under this Agreement by litigation or otherwise because the cost and expense thereof would substantially detract from the benefits intended to be extended to Indemnitee hereunder.  The Company shall indemnify Indemnitee against any and all such Expenses and, if requested by Indemnitee, shall (within ten (10) days after receipt by the Company of a written request therefor) advance, to the extent not prohibited by applicable law, such Expenses to Indemnitee, which are incurred by Indemnitee in connection with any action brought by Indemnitee for indemnification or advancement from the Company under this Agreement or under any directors’ and officers’ liability insurance policies maintained by the Company, regardless of whether Indemnitee ultimately is determined to be entitled to such indemnification, advancement or insurance recovery, as the case may be.

(e)                                   Notwithstanding anything in this Agreement to the contrary (but subject to Section 7 ), no determination as to entitlement to indemnification under this Agreement shall be required to be made prior to the final disposition of the Proceeding; provided , however , that, in absence of any such determination with respect to such Proceeding, the Company shall advance Expenses with respect to such Proceeding.

Section 13.                                     Non-Exclusivity; Survival of Rights; Insurance; Subrogation .

(a)                                  The rights of indemnification and to receive advancement as provided by this Agreement shall not be deemed exclusive of any other rights to which Indemnitee may at any time be entitled under applicable law, the Certificate of Incorporation, the Bylaws, any agreement, a vote of stockholders or a resolution of directors, or otherwise.  No amendment, alteration or repeal of this Agreement or of any provision hereof shall limit or restrict any right of Indemnitee under this Agreement in respect of any action taken or omitted by such Indemnitee in Indemnitee’s Enterprise Status prior to such amendment, alteration or repeal.  To the extent that a change in Delaware law, whether by statute or judicial decision, permits greater indemnification or advancement than would be afforded currently under the Certificate of Incorporation, the Bylaws or this Agreement, it is the intent of the parties hereto that Indemnitee shall enjoy by this Agreement the greater benefits so afforded by such change.  No right or remedy herein conferred is intended to be exclusive of any other right or remedy, and every other right and remedy shall be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise.  The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other right or remedy.

(b)                                  The Company hereby acknowledges that Indemnitee may have certain rights to indemnification, advancement and insurance provided by one or more Persons with whom or which Indemnitee may be associated (including any Sponsor Entity).  The Company hereby acknowledges and agrees that (i) the Company shall be the indemnitor of first resort with respect to any Proceeding, Expense, Liability or matter that is the subject of the Indemnity Obligations, (ii) the Company shall be primarily liable for all Indemnity Obligations and any indemnification afforded to Indemnitee in respect of any Proceeding, Expense, Liability or matter that is the subject of Indemnity Obligations, whether created by applicable law, organizational or constituent documents, contract (including this Agreement) or otherwise, (iii) any obligation of any other Persons with whom or which Indemnitee may be associated (including any Sponsor Entity) to indemnify Indemnitee or advance Expenses or Liabilities to Indemnitee in respect of any Proceeding shall be secondary to the obligations of the Company hereunder, (iv) the Company shall be required to indemnify Indemnitee and advance Expenses or Liabilities to Indemnitee hereunder to the fullest extent provided herein without regard to any rights Indemnitee may have against any other Person with whom or which Indemnitee may be associated (including, any Sponsor Entity) or insurer of any such Person and (v) the Company irrevocably waives, relinquishes and releases any other Person with whom or which Indemnitee may be associated (including any Sponsor Entity) from any claim of contribution, subrogation or any other recovery of any kind in respect of amounts paid by the Company hereunder.  In the event any other Person with whom or which Indemnitee may be associated (including any Sponsor Entity) or their insurers advances or extinguishes any liability or loss which is the subject of any Indemnity Obligation owed by the Company or payable under any Company insurance policy, the payor shall have a right of subrogation against the Company or its insurer or insurers for all amounts so paid which would otherwise be payable by the Company or its insurer or insurers under this Agreement.  In no event will payment of an Indemnity Obligation by any other Person with whom or which Indemnitee may be associated (including any Sponsor Entity) or their insurers affect the obligations of the Company hereunder or shift primary liability for any Indemnity Obligation to any other Person with whom or which Indemnitee may be associated (including any Sponsor Entity).  Any indemnification, insurance or advancement provided by any other Person with whom or which Indemnitee may be associated (including any Sponsor Entity) with respect to any Liability arising as a result of Indemnitee’s Enterprise Status or capacity as an officer or director of any Person is specifically in excess over any Indemnity Obligation of the Company or valid and any collectible insurance (including to any malpractice insurance or professional errors and omissions insurance) provided by the Company under this Agreement.

(c)                                   To the extent that the Company maintains an insurance policy or policies providing liability insurance for directors, officers, employees, or agents of the Company or of any other Enterprise, Indemnitee shall be covered by such policy or policies in accordance with its or their terms to the maximum extent of the coverage available for any such director, officer, employee, agent or fiduciary under such policy or policies and such policies shall provide for and recognize that the insurance policies are primary to any rights to indemnification, advancement or insurance proceeds to which Indemnitee may be entitled from one or more Persons with whom or which Indemnitee may be associated (including any Sponsor Entity) to the same extent as the Company’s indemnification and

12

advancement obligations set forth in this Agreement.  If, at the time of the receipt of a notice of a claim pursuant to the terms hereof, the Company has director and officer liability insurance in effect, the Company shall give prompt notice of the commencement of such Proceeding to the insurers in accordance with the procedures set forth in the respective policies.  The Company shall thereafter take all necessary or desirable action to cause such insurers to pay, on behalf of Indemnitee, all amounts payable as a result of such Proceeding in accordance with the terms of such policies.

(d)                                  In the event of any payment under this Agreement, the Company shall not be subrogated to the rights of recovery of Indemnitee, including rights of indemnification provided to Indemnitee from any other person or entity with whom Indemnitee may be associated (including any Sponsor Entity); provided , however , that the Company shall be subrogated to the extent of any such payment of all rights of recovery of Indemnitee under insurance policies of the Company or any of its subsidiaries.

(e)                                   The indemnification and contribution provided for in this Agreement will remain in full force and effect regardless of any investigation made by or on behalf of Indemnitee.

Section 14.                                     Duration of Agreement .  This Agreement shall continue during the period the Indemnitee is a director, officer, employee, agent or fiduciary of the Company or any other Enterprise, and shall continue thereafter with respect to any possible claims based on the fact that the Indemnitee was a director, officer, employee, agent or fiduciary of the Company or any other Enterprise.  This Agreement shall be binding upon the Company and its successors and assigns and shall inure to the benefit of Indemnitee and Indemnitee’s heirs, executors and administrators.

Section 15.                                     Severability .  If any provision or provisions of this Agreement shall be held to be invalid, illegal or unenforceable for any reason whatsoever: (a) the validity, legality and enforceability of the remaining provisions of this Agreement (including each portion of any Section of this Agreement containing any such provision held to be invalid, illegal or unenforceable that is not itself invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby and shall remain enforceable to the fullest extent permitted by applicable law; (b) such provision or provisions shall be deemed reformed to the extent necessary to conform to applicable law and to give the maximum effect to the intent of the parties hereto; and (c) to the fullest extent possible, the provisions of this Agreement (including each portion of any Section of this Agreement containing any such provision held to be invalid, illegal or unenforceable that is not itself invalid, illegal or unenforceable) shall be construed so as to give effect to the intent manifested thereby.

Section 16.                                     Enforcement .

(a)                                  The Company expressly confirms and agrees that it has entered into this Agreement and assumed the obligations imposed on it hereby in order to induce Indemnitee to serve as a director, officer, employee, agent or fiduciary of the Company, and the Company acknowledges that Indemnitee is relying upon this Agreement in serving as a director, officer, employee, agent or fiduciary of the Company.

13

(b)                                  This Agreement hereby amends and restates the Original Agreement in all respects.  This Agreement constitutes the entire agreement between the parties hereto with respect to the subject matter hereof and supersedes all prior agreements and understandings, oral, written and implied, between the parties hereto with respect to the subject matter hereof, including, without limitation, the Original Agreement; provided , however , that this Agreement is a supplement to and in furtherance of the Certificate of Incorporation, the Bylaws and applicable law, and shall not be deemed a substitute therefor, nor diminish or abrogate any rights of Indemnitee thereunder.

(c)                                   The Company shall not seek from a court, or agree to, a “bar order” that would have the effect of prohibiting or limiting the Indemnitee’s rights to receive advancement of expenses under this Agreement.

Section 17.                                     Modification and Waiver .  No supplement, modification or amendment of this Agreement shall be binding unless executed in writing by the parties thereto.  No waiver of any of the provisions of this Agreement shall be deemed to be or shall constitute a waiver of any other provision of this Agreement nor shall any waiver constitute a continuing waiver.

Section 18.                                     Notices .  All notices, requests, demands and other communications under this Agreement shall be in writing and shall be deemed to have been duly given if (a) delivered by hand and receipted for by the party to whom said notice or other communication shall have been directed, (b) mailed by certified or registered mail with postage prepaid, on the third business day after the date on which it is so mailed, (c) mailed by reputable overnight courier and receipted for by the party to whom said notice or other communication shall have been directed or (d) sent by facsimile transmission, with receipt of oral confirmation that such transmission has been received:

(a)                                  If to Indemnitee, at the address indicated on the signature page of this Agreement, or such other address as Indemnitee shall provide to the Company.

(b)                                  If to the Company to:

Antero Resources Corporation
1615 Wynkoop Street
Denver, Colorado 80202

or to any other address as may have been furnished to Indemnitee by the Company.

Section 19.                                     Contribution .

(a)                                  Regardless of whether the indemnification provided in this Agreement is available, in respect of any Proceeding in which the Company is jointly liable with Indemnitee (or would be jointly liable, if joined in such Proceeding), the Company shall, unless indemnification would not be available as a result of Section 7(a) , Section 7(b)  or Section 7(c) , pay, in the first instance, the entire amount of any Liability from such Proceeding without requiring Indemnitee to contribute to such payment and, to the fullest extent permitted by applicable law, the Company hereby waives and relinquishes any right

14

of contribution it may have against Indemnitee.  The Company shall not enter into any settlement of any Proceeding in which the Company is jointly liable with Indemnitee (or would be jointly liable, if joined in such Proceeding) unless such settlement provides for a full and final release of all claims asserted against Indemnitee.

(b)                                  Without diminishing or impairing the obligations of the Company set forth in Section 19(a) , if, for any reason, Indemnitee shall elect or be required to pay all or any portion of any Liability in any Proceeding in which the Company is jointly liable with Indemnitee (or would be jointly liable, if joined in such Proceeding), to the fullest extent permitted by applicable law, the Company shall contribute to the amount of Expenses and Liabilities actually and reasonably incurred and paid or payable by Indemnitee in proportion to the relative benefits received by the Company and all officers, directors or employees of the Company, other than Indemnitee, who are jointly liable with Indemnitee (or would be jointly liable, if joined in such Proceeding), on the one hand, and Indemnitee, on the other hand, from the transaction or events from which such Proceeding arose; provided , however , that the proportion determined on the basis of relative benefit may, to the extent necessary to conform to law, be further adjusted by reference to the relative fault of the Company and all officers, directors or employees of the Company other than Indemnitee who are jointly liable with Indemnitee (or would be jointly liable, if joined in such Proceeding), on the one hand, and Indemnitee, on the other hand, in connection with the transaction or events that resulted in such Expenses and Liabilities, as well as any other equitable considerations that applicable law may require to be considered.  The relative fault of the Company and all officers, directors or employees of the Company, other than Indemnitee, who are jointly liable with Indemnitee (or would be jointly liable, if joined in such Proceeding), on the one hand, and Indemnitee, on the other hand, shall be determined by reference to, among other things, the degree to which their actions were motivated by intent to gain personal profit or advantage, the degree to which their liability is primary or secondary and the degree to which their conduct is active or passive.

(c)                                   The Company hereby agrees to fully indemnify and hold Indemnitee harmless from any claims of contribution that may be brought by officers, directors, or employees of the Company, other than Indemnitee, who may be jointly liable with Indemnitee.

(d)                                  To the fullest extent permissible under applicable law, if the indemnification provided for in this Agreement is unavailable to Indemnitee for any reason whatsoever, other than the reasons set forth in Section 7(a) , Section 7(b)  or Section 7(c) , the Company, in lieu of indemnifying Indemnitee, shall contribute to the amount incurred by Indemnitee, whether for Liabilities or for Expenses, in connection with any claim relating to an indemnifiable event under this Agreement, in such proportion as is deemed fair and reasonable in light of all of the circumstances of such Proceeding in order to reflect (i) the relative benefits received by the Company and Indemnitee as a result of the event(s) and transaction(s) giving cause to such Proceeding; and (ii) the relative fault of the Company (and its directors (other than Indemnitee), officers, employees and agents) and Indemnitee in connection with such event(s) and transaction(s).

Section 20.                                     Applicable Law and Consent to Jurisdiction .  This Agreement and the legal relations among the parties shall be governed by, and construed and enforced in accordance with, the laws of the State of Delaware, without regard to its conflict of laws rules.  Except with respect to any arbitration commenced by Indemnitee pursuant to Section 12(a)  of this Agreement, the Company and Indemnitee hereby irrevocably and unconditionally (i) agree that any action or proceeding arising out of or in connection with this Agreement shall be brought only in the Chancery Court of the State of Delaware (the “ Delaware Court ”), and not in any other state or federal court in the United States of America or any court in any other country, (ii) consent to submit to the exclusive jurisdiction of the Delaware Court for purposes of any action or proceeding arising out of or in connection with this Agreement, (iii) waive any objection to the laying of venue of any such action or proceeding in the Delaware Court, and (iv) waive, and agree not to plead or to make, any claim that any such action or proceeding brought in the Delaware Court has been brought in an improper or inconvenient forum.

Section 21.                                     Counterparts .  This Agreement may be executed in one or more counterparts, each of which shall for all purposes be deemed to be an original but all of which together shall constitute one and the same Agreement.  Only one such counterpart signed by the party against whom enforceability is sought needs to be produced to evidence the existence of this Agreement.

Section 22.                                     Third-Party Beneficiaries .  The Sponsor Entities are intended third-party beneficiaries of this Agreement and shall have all of the rights afforded to Indemnitee under this Agreement.
