WHEREAS, the Board of Directors of the General Partner (the “Board”) has determined that the increased difficulty in attracting and retaining such persons is detrimental to the best interests of the Partnership and its unitholders and that the Companies should act to assure such persons that there will be increased certainty of such protection in the future;

Section 4.                                           Indemnification for Expenses of a Party Who is Wholly or Partly Successful. Notwithstanding any other provisions of this Agreement, and without limiting the rights of Indemnitee under any other provision hereof, including any rights to indemnification pursuant to Sections 2 or 3 hereof, to the fullest extent permitted by applicable law, to the extent that Indemnitee is successful, on the merits or otherwise, in any Proceeding or in defense of any claim, issue, or matter therein, in whole or in part, the Companies, jointly and severally, shall indemnify Indemnitee against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection with each successfully resolved Proceeding, claim, issue, or matter.  For purposes of this Section 4 and without limitation, the termination of any Proceeding or claim, issue or matter in such a Proceeding by dismissal, with or without prejudice, shall be deemed to be a successful result as to such claim, issue or matter.

(a)                                 the fullest extent permitted by the provisions of the Delaware Acts that authorize or contemplate additional indemnification by agreement, or the corresponding provision of any amendment to or replacement of the Delaware Acts; and

(b)                                 the fullest extent authorized or permitted by any amendments to or replacements of the Delaware Acts adopted after the date of this Agreement that increase the extent to which a limited partnership or limited liability company, as applicable, may indemnify its officers and directors.

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

(a)                                 for which payment has actually been made to or on behalf of Indemnitee under any insurance policy obtained by a Company except with respect to any excess beyond the amount paid under such insurance policy;

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

(c)                                  except as provided in Section 12(d) of this Agreement, in connection with any Proceeding (or any part of any Proceeding) initiated by Indemnitee or any Sponsor Entity, including any Proceeding (or any part of any Proceeding) initiated by Indemnitee or any Sponsor Entity against a Company 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) a Company provides the indemnification, in its sole discretion, pursuant to the powers vested in such Company under applicable law; or

(d)                                 if a final decision by a court having jurisdiction in the matter shall determine that such indemnification is not lawful.

Section 8.                                           Advancement.  In accordance with the pre-existing requirements of the Company Organizational Documents, and notwithstanding any provision of this Agreement to the contrary, the Companies shall advance, to the extent not prohibited by law, the Expenses and Liabilities reasonably incurred by Indemnitee in connection with any Proceeding, and such advancement shall be made within thirty (30) days after the receipt by the General Partner of a

5

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 General Partner to support the advances claimed.  Indemnitee shall qualify for advances upon the execution and delivery to the Companies 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 that Indemnitee is not entitled to be indemnified by the Companies.  This Section 8 shall not apply to any claim made by Indemnitee for which indemnity is excluded pursuant to Section 7 hereof.

Section 9.                                           Procedure for Notification and Defense of Claim.

(a)                                 Indemnitee shall promptly notify the General Partner in writing of any Proceeding with respect to which Indemnitee intends to seek indemnification or advancement hereunder following the receipt by Indemnitee of written notice thereof.  The written notification to the General Partner 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 General Partner 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 action, suit or proceeding.  Any delay or failure by Indemnitee to notify the General Partner hereunder will not relieve the Companies from any liability which they may have to Indemnitee hereunder or otherwise than under this Agreement, and any delay or failure in so notifying a Company shall not constitute a waiver by Indemnitee of any rights under this Agreement.  The Secretary of the General Partner 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 Companies to defend Indemnitee in such Proceeding, at the sole expense of the Companies (which approval shall not be unreasonably withheld, conditioned or delayed), or (ii) have the Companies assume the defense of Indemnitee in such Proceeding, in which case the Companies shall assume the defense of such Proceeding with counsel selected by the Companies and approved by Indemnitee (which approval shall not be unreasonably withheld, conditioned or delayed) within ten (10) days of the General Partners’ receipt of written notice of Indemnitee’s election to cause the Companies to do so.  If the Companies are required to assume the defense of any such Proceeding, they shall engage legal counsel for such defense, and the Companies 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 Companies (and any other party or parties entitled to be indemnified by the Companies 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 Companies (or any other such party or parties) or there are legal defenses available to Indemnitee that are not available to

6

the Companies (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 Companies shall reasonably cooperate in the defense of any Proceeding with respect to which indemnification is sought hereunder, regardless of whether the Companies or Indemnitee assumes the defense thereof.  Indemnitee may not settle or compromise any Proceeding without the prior written consent of the General Partner, which consent shall not be unreasonably withheld, conditioned or delayed.  The Companies may not settle or compromise any proceeding without the prior written consent of Indemnitee.

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 Companies 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 by the Board, by the unitholders of the Partnership; and, if it is so determined that Indemnitee is entitled to indemnification, payment to Indemnitee shall be made within ten (10) days after such determination.  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 Companies (irrespective of the determination as to Indemnitee’s entitlement to indemnification) and the Companies hereby indemnify and agree to hold Indemnitee harmless therefrom.  The Companies 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 Companies agree 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, (i) the Independent Counsel shall be selected by the Companies within ten (10) days of the Submission Date (the cost of such Independent Counsel to be paid by the Companies), (ii) the General Partner shall give written notice to Indemnitee advising it of the identity of the Independent Counsel so selected and (iii) Indemnitee may, within ten (10) days after such written notice of selection shall have been given, deliver to the Companies Indemnitee’s written objection to such selection.  Such objection

7

by Indemnitee 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 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 submission by Indemnitee of a written request for indemnification pursuant to Section 10(a) hereof (the “Submission Date”) and (ii) ten (10) days after the final disposition of the Proceeding, each of the Companies 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 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 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 Companies shall, to the fullest extent not prohibited by 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 a 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 a 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 sixty (60) days after receipt by such Company of the request therefore, the requisite determination of entitlement to indemnification shall, to the fullest extent not prohibited by law, be deemed to have been made and Indemnitee shall be entitled to such indemnification, absent a prohibition of such indemnification under applicable law; provided, however, that such 60-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 Indemnitee objects to the Companies’ 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, however, that such 60 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 unitholders of the Partnership.

8

(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 Companies 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 is based on the records or books of account of the Enterprise, including financial 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 ninety (90) days after receipt by a Company of the request for indemnification, (iv) payment of indemnification is not made pursuant to Sections 4 or 5 or the last sentence of Section 10(a) of this Agreement within ten (10) days after receipt by a Company of a written request therefor, (v) payment of indemnification pursuant to Sections 2, 3 or 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 a 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 a court 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.  No Company shall 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

9

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 Companies 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(a) of this Agreement that Indemnitee is entitled to indemnification, the Companies shall be bound by 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 Companies shall, to the fullest extent not prohibited by 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 Companies are bound by all the provisions of this Agreement.  It is the intent of the Companies 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 Companies, jointly and severally, shall indemnify Indemnitee against any and all Expenses and, if requested by Indemnitee, shall (within ten (10) days after receipt by the Companies of a written request therefore) advance, to the extent not prohibited by law, such Expenses to Indemnitee, which are incurred by Indemnitee in connection with any action brought by Indemnitee for indemnification or advancement from the Companies under this Agreement or under any directors’ and officers’ liability insurance policies maintained by the Companies, 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, 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 that, in absence of any such determination with respect to such Proceeding, the Companies 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 Company Organizational Documents, any agreement, 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 Corporate 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 Company Organizational Documents 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 Companies hereby acknowledge 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, without limitation, any Sponsor Entity).  The Companies hereby acknowledge and agree that (i) the Companies  shall be the indemnitors of first resort with respect to any Proceeding, Expense, Liability or matter that is the subject of the Indemnity Obligations, (ii) the Companies shall be primarily liable for all Indemnification 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 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, without limitation, 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 Companies hereunder, (iv) the Companies 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 Companies irrevocably waive, relinquish and release any other Person with whom or which Indemnitee may be associated (including, without limitation, any Sponsor Entity) from any claim of contribution, subrogation or any other recovery of any kind in respect of amounts paid by the Companies hereunder.  In the event any other Person with whom or which Indemnitee may be associated (including, without limitations, any Sponsor Entity) or their insurers advances or extinguishes any liability or loss which is the subject of any Indemnity Obligation owed by the Companies or payable under any Company’s insurance policy, the payor shall have a right of subrogation against such Company or its insurer or insurers for all amounts so paid which would otherwise be payable by such 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, without limitation, any Sponsor Entity) or their insurers affect the obligations of any Company hereunder or shift primary liability for any Indemnity Obligation to any other Person with whom or which Indemnitee may be associated (including, without limitation, any Sponsor Entity).  Any indemnification, insurance or advancement provided by any other Person with whom or which Indemnitee may be associated (including, without limitation, any Sponsor Entity) with respect to any liability arising as a result of Indemnitee’s Corporate Status or capacity as an officer or director of any Person is specifically in excess over any Indemnity Obligation of a Company or valid and any collectible insurance (including but not limited to any malpractice insurance or professional errors and omissions insurance) provided by a Company under this Agreement.

(c)                                  To the extent that a Company maintains an insurance policy or policies providing liability insurance for directors, officers, employees, or agents of such Company or of any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise which such person serves at the request of a Company, Indemnitee shall be covered by such

11

policy or policies in accordance with its or their terms to the maximum extent of the coverage available for any such director, officer, employee or agent 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, without limitation, any Sponsor Entity) to the same extent as a Company’s indemnification and 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, a Company has director and officer liability insurance in effect, such 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.  Such 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 Companies 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, without limitation, any Sponsor Entity); provided, however, that the Companies shall be subrogated to the extent of any such payment of all rights of recovery of Indemnitee under insurance policies of a Company or any of its subsidiaries.

(e)                                  If the General Partner, on behalf of itself, pays or causes to be paid (including advancement of Expenses), for any reason any amounts otherwise indemnifiable or payable hereunder or under any other indemnification agreement or arrangement (whether pursuant to contact, Company Organizational Documents or otherwise) with Indemnitee, then the Partnership shall fully indemnify, reimburse and hold harmless the General Partner for all such payments actually made by the General Partner.

(f)                                   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; Not Employment Contract.  This Agreement shall continue until and terminate upon the latest of: (i) ten (10) years after the date that Indemnitee shall have ceased to serve as a director, officer, employee or agent of a Company or any other Enterprise and (ii) the date of final termination of any Proceeding then pending in respect of which Indemnitee is granted rights of indemnification or advancement hereunder and of any proceeding commenced by Indemnitee pursuant to Section 12 of this Agreement relating thereto.  This Agreement shall be binding upon the Companies and their successors and assigns and shall inure to the benefit of Indemnitee and Indemnitee’s heirs, executors and administrators.  This Agreement shall not be deemed an employment contract between any Company (or any of its subsidiaries or any Enterprise) and Indemnitee.  Indemnitee specifically acknowledges that Indemnitee’s employment with a Company (or any of its subsidiaries or any Enterprise), if any, is at will, and Indemnitee may be discharged at any time for any reason, with or without cause, except as may be otherwise provided in any written employment contract between Indemnitee and any Company (or any of its subsidiaries or any Enterprise), other applicable formal

12

severance policies duly adopted by the Board, or, with respect to service as a director of the General Partner, by the Company Organizational Documents and the Delaware Acts.

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 without limitation, 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 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, without limitation, 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 Companies expressly confirm and agree that they have entered into this Agreement and assumed the obligations imposed on them hereby in order to induce Indemnitee to serve as a director, officer, employee or agent of a Company, and such Company acknowledges that Indemnitee is relying upon this Agreement in serving as a director, officer, employee or agent of such Company.

(b)                                 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; provided, however, that this Agreement is a supplement to and in furtherance of the Company Organizational Documents and applicable law, and shall not be deemed a substitute therefore, nor diminish or abrogate any rights of Indemnitee thereunder.

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:

Section 19.                                    Contribution.  To the fullest extent permissible under applicable law, if the indemnification provided for in this Agreement is unavailable to Indemnitee for any reason whatsoever, the Companies, 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 Companies and Indemnitee as a result of the event(s) and transaction(s) giving cause to such Proceeding; and (ii) the relative fault of the Companies (and their directors, 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 Companies 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.

Section 23.                                    Miscellaneous.  Use of the masculine pronoun shall be deemed to include usage of the feminine pronoun where appropriate.  The headings of the paragraphs of this

Agreement are inserted for convenience only and shall not be deemed to constitute part of this Agreement or to affect the construction thereof.
