(a) Limitation. No Person will be liable to the Company or its Member for any loss, damage, liability or expense suffered by the Company or its Member on account of any action taken or omitted to be taken on or after October 14, 2010 by such Person as a Member, Representative or Officer of the Company or by such Person while serving at the request of the Company as a director, officer or in any other comparable position of any Other Enterprise, if such Person discharges such Person’s duties in good faith, exercising the same degree of care and skill that a prudent person would have exercised under the circumstances in the conduct of such prudent person’s own affairs, and in a manner such Person reasonably believes to be in the best interest of the Company. The Member’s, Representative’s or Officer’s liability hereunder is limited only for those actions taken or omitted to be taken by such Member, Representative or Officer in connection with the management of the business and affairs of the Company.

(b) Right to Indemnification. The Company will indemnify each Person who has been or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative, investigative or appellate (regardless of whether such action, suit or proceeding is by or in the right of the Company or by third parties) by reason of the fact that such Person is or was a Member, Representative or Officer after October 14, 2010, or is or was serving at the request of the Company after October 14, 2010 as a director, officer or in any other comparable position of any Other Enterprise against all liabilities and expenses, including judgments, amounts paid in settlement, attorneys’ fees, excise taxes or penalties, fines and other expenses, actually and reasonably incurred by such Person after October 14, 2010 in connection with such action, suit or proceeding (including the investigation, defense,

settlement or appeal of such action, suit or proceeding); provided, however, that the Company is not required to indemnify or advance expenses to any Person from or on account of such Person’s conduct that was finally adjudged to have been knowingly fraudulent, deliberately dishonest or willful misconduct; provided, further, that the Company is not required to indemnify or advance expenses to any Person in connection with an action, suit or proceeding initiated by such Person unless the initiation of such action, suit or proceeding was authorized in advance by the Member; provided, further, that a Member, Representative or Officer will be indemnified hereunder only for those actions taken or omitted to be taken by such Member, Representative or Officer in connection with the management of the business and affairs of the Company or any Other Enterprise and that the provisions of this Section 5.5 are not intended to extend indemnification to the Member, the Representative or any Officer for any actions taken or omitted to be taken by the Member in any other connection, including any other express obligation of the Member, the Representative or any Officer undertaken in this Agreement; provided, further, that the Company will not indemnify Laura L. Luce or Geof Storey. The termination of any action, suit or proceeding by judgment, order, settlement, conviction or under a plea of nolo contendere or its equivalent, will not, of itself, create a presumption that such Person’s conduct was finally adjudged to have been knowingly fraudulent, deliberately dishonest or willful misconduct.

(c) Enforcement of Indemnification. If the Company refuses to indemnify any Person who may be entitled to be indemnified or to have expenses advanced under this Section 5.5, such Person may maintain an action in any court of competent jurisdiction against the Company to determine whether or not such Person is entitled to such indemnification or advancement of expenses hereunder. If such court action is successful and the Person is determined to be entitled to such indemnification or advancement of expenses, such Person will be reimbursed by the Company for all fees and expenses (including attorneys’ fees) actually and reasonably incurred in connection with any such action (including the investigation, defense, settlement or appeal of such action).

(d) Advancement of Expenses. Expenses (including attorneys’ fees) reasonably incurred in defending an action, suit or proceeding, whether civil, criminal, administrative, investigative or appellate, must be paid by the Company in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such Person to repay such amount if it is ultimately determined that such Person is not entitled to indemnification by the Company. In no event will any advance be made in instances where the Member or independent legal counsel reasonably determines that such Person would not be entitled to indemnification hereunder.

(e) Non-Exclusivity. The indemnification and the advancement of expenses provided by this Section 5.5 are not exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any statute, or any agreement, policy of insurance or otherwise, both as to action in their official capacity and as to action in another capacity while holding their respective offices, and do not limit in any way any right that the Company may have to make additional indemnifications with respect to the same or different Persons or classes of Persons. The

indemnification and advancement of expenses provided by, or granted pursuant to, this Section 5.5 will continue as to a Person who has ceased to be a Member, Representative or Officer of the Company, and as to a Person who has ceased serving at the request of the Company as a director, officer or in any other comparable position of any Other Enterprise and will inure to the benefit of the heirs, executors and administrators of such Person.

(f) Insurance. Upon the approval of the Member, the Representative or any Officer, the Company may purchase and maintain insurance on behalf of any Person who is or was a Member, Representative, Officer agent or employee of the Company, or is or was serving at the request of the Company as a director, officer or in any other comparable position of any Other Enterprise, against any liability asserted against such Person and incurred by such Person in any such capacity, or arising out of such Person’s status as such, whether or not the Company would have the power, or the obligation, to indemnify such Person against such liability under the provisions of this Section 5.5.

(g) Amendment and Vesting of Rights. Notwithstanding any other provision of this Agreement, the terms and provisions of this Section 5.5 may not be amended or repealed and the rights to indemnification and advancement of expenses created hereunder may not be changed, altered or terminated except by the Member. The rights granted or created hereby are vested in each Person entitled to indemnification hereunder as a bargained-for, contractual condition of such Person’s serving or having served as a Member, Representative or Officer of the Company or serving at the request of the Company as a director, officer or in any other comparable position of any Other Enterprise and, while this Section 5.5 may be amended or repealed, no such amendment or repeal will release, terminate or adversely affect the rights of such Person under this Section 5.5 with respect to any act taken or the failure to take any act by such Person prior to such amendment or repeal or with respect to any action, suit or proceeding with respect to such act or failure to act filed after such amendment or repeal.

(i) The “Company” includes, in addition to the resulting or surviving limited liability company (or other entity), any constituent limited liability company (or other entity) (including any constituent of a constituent) absorbed in a consolidation or merger so that any Person who is or was a member or manager of such constituent limited liability company (or other entity), or is or was serving at the request of such constituent limited liability company (or other entity) as a director, officer or in any other comparable position of any Other Enterprise will stand in the same position under the provisions of this Section 5.5 with respect to the resulting or surviving limited liability company as such Person would if such Person had served the resulting or surviving limited liability company (or other entity) in the same capacity;

(ii) “Other Enterprises” or “Other Enterprise” include, without limitation, any other limited liability company, corporation, partnership, joint venture, trust or employee benefit plan;

(iii) “fines” includes any excise taxes assessed against a person with respect to an employee benefit plan;

(iv) “defense” includes investigations of any threatened, pending or completed action, suit or proceeding as well as appeals thereof and also includes any defensive assertion of a cross-claim or counterclaim; and

(v) “serving at the request of the Company” includes any service as a director, officer or in any other comparable position that imposes duties on, or involves services by, a Person with respect to an employee benefit plan, its participants, or beneficiaries; and a Person who acted in good faith and in a manner such Person reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan is deemed to have acted “in the best interest of the Company” as referred to in this Section 5.5.

(i) Severability. If any provision of this Section 5.5 or the application of any such provision to any Person or circumstance is held invalid, illegal or unenforceable for any reason whatsoever, the remaining provisions of this Section 5.5 and the application of such provision to other Persons or circumstances will not be affected thereby and, to the fullest extent possible, the court finding such provision invalid, illegal or unenforceable must modify and construe the provision so as to render it valid and enforceable as against all Persons and to give the maximum possible protection to Persons subject to indemnification hereby within the bounds of validity, legality and enforceability. Without limiting the generality of the foregoing, if the Member, the Representative or any Officer or any Person who is or was serving at the request of the Company as a director, officer or in any other comparable position of any Other Enterprise, is entitled under any provision of this Section 5.5 to indemnification by the Company for some or a portion of the judgments, amounts paid in settlement, attorneys’ fees, ERISA excise taxes or penalties, fines or other expenses actually and reasonably incurred by any such Person in connection with any threatened, pending or completed action, suit or proceeding (including the investigation, defense, settlement or appeal of such action, suit or proceeding), whether civil, criminal, administrative, investigative or appellate, but not, however, for all of the total amount thereof, the Company must nevertheless indemnify such Person for the portion thereof to which such Person is entitled.

5.6 Contracts with the Member, the Representative, Officers or Affiliates. No contract or transaction between the Company and the Member, the Representative or any Officer or between the Company and any Person in which the Member, the Representative or any Officer is a director or officer, or has a financial interest, will be void or voidable solely for this reason, and the Member, the Representative or applicable Officer will not be obligated to account to the Company for any profit or benefit derived by the Member, the Representative or applicable Officer if the Member consents to such contract or transaction.

Company, and neither the Company nor the Member have any right by virtue of this Agreement in or to such other business ventures or to the income or profits derived therefrom.

Except to the extent that a Transferee becomes a Substitute Member, such Transferee will not be entitled to exercise any rights as a Member in the Company, including the right to vote, grant approvals, or give consents with respect to the applicable Interest, the right to require any information or accounting of the Company’s business or the right to inspect the Company’s books and records, but such Transferee will only be entitled to receive, to the extent of the Interest transferred to such Transferee, the Distributions attributable thereto.

7.2 Redemption of Interests. Any Interest may be redeemed by the Company, by purchase or otherwise, as determined by the Member.

8.1 Events Causing Dissolution. The Company will be dissolved only upon the first to occur of the following events:

In connection with such winding up, the Member may liquidate and reduce to cash (to the extent necessary or appropriate) the assets of the Company as promptly as is consistent with obtaining Fair Value therefor, to apply and distribute the proceeds of such liquidation and any remaining assets in accordance with the provisions of Section 8.3, and to do any and all acts and things authorized by, and in accordance with, the Act and other applicable laws for the purpose of winding up and liquidation.
