     8. Limited Liability. Except as otherwise provided by the Act, the debts, obligations and liabilities of the Company, whether arising in contract, tort or otherwise, shall be solely the debts, obligations and liabilities of the Company, and the Member shall not be obligated personally for any such debt, obligation or liability of the Company solely by reason of being a member of the Company.

     9. Capital Contributions. The Member may make capital contributions to the Company, in cash, property or other assets as the Member in its sole discretion shall determine from time to time, but shall have no obligation to do so.

     10. Allocation of Profits and Losses. The Company’s profits and losses shall be allocated solely to the Member.

     11. Distributions. Distributions shall be made to the Member at the times and in the aggregate amounts determined by the Member. Notwithstanding any provision to the contrary contained in this Agreement, the Company shall not make a distribution to the Member on account of its interest in the Company if such distribution would violate Section 18-607 of the Act or other applicable Law. “Law” means any applicable constitutional provision, statute, act, code, law, regulation, rule, ordinance, order, decree, ruling, proclamation, resolution, judgment, decision, declaration or interpretative or advisory opinion or letter of a governmental authority.

     12. Management. The management of the Company shall be exclusively vested in a Board of Directors (the “Board” or “Board of Directors”) and, subject to the direction of the Board, the officers (the “Officers”), who shall collectively (Board and Officers) constitute “managers” of the Company within the meaning of the Act. The authority and functions of the Board on the one hand and of the Officers on the other shall be identical to the activity and functions of the board of directors and officers, respectively, of a corporation organized under the Delaware General Corporation Law. Thus, the business and affairs of the Company shall be managed by the Board, and the day-to-day activities of

the Company shall be conducted on the Company’s behalf by the Officers, who shall be agents of the Company.

     13. Board of Directors. The Board shall consist of one or more individuals (the “Directors”) appointed by the Member, such number of Directors to be determined from time to time by the Member. Vacancies on the Board for whatever cause shall be filled by the Member. The Directors shall hold office until their respective successors are chosen and qualify or until their earlier death, resignation or until removed by the Member, in the Member’s discretion. The Board may act (a) by majority vote of Directors present at a meeting at which a quorum (consisting of a majority of Directors) is present or (b) by written consent of a majority of the Directors.

     14. Officers. The Board may, from time to time as it deems advisable, select natural persons, who shall be agents of the Company, and designate them as Officers of the Company and assign titles (including, without limitation, Chairman, President, Vice President, Secretary, Treasurer, Assistant Secretary and Assistant Treasurer) to any such person. Unless the Board decides otherwise, if the title is one commonly used for officers of a business corporation formed under the Delaware General Corporation Law, the assignment of such title shall constitute the delegation to such person of the authorities and duties that are normally associated with that office. Any delegation pursuant to this Section 14 may be revoked at any time by the Board. An Officer may be removed with or without cause by the Board.

     15. Other Business. The Member may engage in or possess an interest in other business ventures of every kind and description, independently or with others. The Company shall not have any rights in or to such independent ventures or the income or profits therefrom by virtue of this Agreement.

     16. Indemnification.

     (a) To the fullest extent permitted by Law but subject to the limitations expressly provided in this Agreement, each Indemnitee (as defined below) shall be indemnified and held harmless by the Company from and against any and all losses, claims, damages, liabilities (joint or several), expenses (including reasonable legal fees and expenses), judgments, fines, penalties, interest, settlements and other amounts arising from any and all claims, demands, actions, suits or proceedings, whether civil, criminal, administrative or investigative, in which any such person may be involved, or is threatened to be involved, as a party or otherwise, by reason of such person’s status as (i) a present or former member of the Board of Directors or any committee thereof, (ii) a present or former Member, (iii) a present or former Officer, or (iv) a Person serving at the request of the Company in another entity in a similar capacity as that referred to in the immediately preceding clauses (i) or (iii), provided, that the Person described in the immediately preceding clauses (i), (ii), (iii) or (iv) (“Indemnitee”) shall not be indemnified and held harmless if there has been a final and non-appealable judgment entered by a court of competent jurisdiction determining that, in respect

of the matter for which the Indemnitee is seeking indemnification pursuant to this Section 16, the Indemnitee acted in bad faith or engaged in fraud, willful misconduct or, in the case of a criminal matter, acted with knowledge that the Indemnitee’s conduct was unlawful. Any indemnification pursuant to this Section 16 shall be made only out of the assets of the Company.

     (b) To the fullest extent permitted by Law, expenses (including reasonable legal fees and expenses) incurred by an Indemnitee who is indemnified pursuant to Section 16(a) in defending any claim, demand, action, suit or proceeding shall, from time to time, be advanced by the Company prior to the final disposition of such claim, demand, action, suit or proceeding upon receipt by the Company of an undertaking by or on behalf of the Indemnitee to repay such amount if it shall be determined that the Indemnitee is not entitled to be indemnified as authorized in this Section 16.

     (c) The indemnification provided by this Section 16 shall be in addition to any other rights to which an Indemnitee may be entitled under any agreement, as a matter of Law or otherwise, both as to actions in the Indemnitee’s capacity as an Indemnitee and as to actions in any other capacity, and shall continue as to an Indemnitee who has ceased to serve in such capacity.

     (d) The Company may purchase and maintain insurance, on behalf of the members of the Board of Directors, the Officers and such other persons as the Board of Directors shall determine, against any liability that may be asserted against or expense that may be incurred by such person in connection with the Company’s activities or such person’s activities on behalf of the Company, regardless of whether the Company would have the power to indemnify such person against such liability under the provisions of this Agreement.

     (e) For purposes of this Section 16, the Company shall be deemed to have requested an Indemnitee to serve as fiduciary of an employee benefit plan whenever the performance by the Indemnitee of such Indemnitee’s duties to the Company also imposes duties on, or otherwise involves services by, the Indemnitee to the plan or participants or beneficiaries of the plan; excise taxes assessed on an Indemnitee with respect to an employee benefit plan pursuant to applicable Law shall constitute “fines” within the meaning of Section 16; and action taken or omitted by the Indemnitee with respect to an employee benefit plan in the performance of such Indemnitee’s duties for a purpose reasonably believed by such Indemnitee to be in the interest of the participants and beneficiaries of the plan shall be deemed to be for a purpose which is in, or not opposed to, the best interests of the Company.

     (f) In no event may an Indemnitee subject any Members of the Company to personal liability by reason of the indemnification provisions of this Agreement.

     (g) An Indemnitee shall not be denied indemnification in whole or in part under this Section 16 because the Indemnitee had an interest in the transaction with respect to which the indemnification applies if the transaction was otherwise permitted by the terms of this Agreement.

     (h) The provisions of this Section 16 are for the benefit of the Indemnitees, their heirs, successors, assigns and administrators and shall not be deemed to create any rights for the benefit of any other Persons.

     (i) No amendment, modification or repeal of this Section 16 or any provision hereof shall in any manner terminate, reduce or impair either the right of any past, present or future Indemnitee to be indemnified by the Company or the obligation of the Company to indemnify any such Indemnitee under and in accordance with the provisions of this Section 16 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted, and provided such Person became an Indemnitee hereunder prior to such amendment, modification or repeal.

     (j) THE PROVISIONS OF THE INDEMNIFICATION PROVIDED IN THIS SECTION 16 ARE INTENDED BY THE PARTIES TO APPLY EVEN IF SUCH PROVISIONS HAVE THE EFFECT OF EXCULPATING THE INDEMNITEE FROM LEGAL RESPONSIBILITY FOR THE CONSEQUENCES OF SUCH PERSON’S NEGLIGENCE, FAULT OR OTHER CONDUCT.

     17. Liability of Indemnitees.

     (a) Notwithstanding anything to the contrary set forth in this Agreement, no Indemnitee shall be liable for monetary damages to the Company, the Members or any other Person for losses sustained or liabilities incurred as a result of any act or omission of an Indemnitee unless there has been a final and non-appealable judgment entered in a court of competent jurisdiction determining that, in respect of the matter in question, the Indemnitee acted in bad faith or engaged in fraud, willful misconduct or, in the case of a criminal matter, acted with knowledge that the Indemnitee’s conduct was criminal.

     (b) Subject to its obligations and duties as set forth in Sections 12 and 13, the Board of Directors and any committee thereof may exercise any of the powers granted to it by this Agreement and perform any of the duties imposed upon it hereunder either directly or by or through the Company’s Officers or agents, and neither the Board of Directors nor any committee thereof shall be responsible for any misconduct or negligence on the part of any such Officer or agent appointed by the Board of Directors or any committee thereof in good faith.

     (c) Any amendment, modification or repeal of this Section 17 or any

provision hereof shall be prospective only and shall not in any way affect the limitations on liability under this Section 17 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may be asserted.

     18. Assignments. The Member may at any time assign in whole or in part its limited liability company interest in the Company. If the Member transfers all of its interest in the Company pursuant to this Section 18, the transferee shall be admitted to the Company upon its execution of an instrument signifying its agreement to be bound by the terms and conditions of this Agreement. Such admission shall be deemed effective immediately prior to the transfer, and, immediately following such admission, the transferor Member shall cease to be a member of the Company.

     19. Resignation. The Member may at any time resign from the Company. If the Member resigns pursuant to this Section 19, an additional member shall be admitted to the Company, subject to Section 20 hereof, upon its execution of an instrument signifying its agreement to be bound by the terms and conditions of this Agreement. Such admission shall be deemed effective immediately prior to the resignation, and, immediately following such admission, the resigning Member shall cease to be a member of the Company.

     (b) The bankruptcy of the Member shall not cause the Member to cease to be a member of the Company and upon the occurrence of such an event, the business of the Company shall continue without dissolution.

     22. Severability of Provisions. Each provision of this Agreement shall be considered severable, and if for any reason any provision or provisions herein are determined to be invalid, unenforceable or illegal under any existing or future Law, such invalidity, unenforceability or illegality shall not impair the operation of or affect those portions of this Agreement that are valid, enforceable and legal.

     23. Entire Agreement; Interpretation Under the Act. This Agreement constitutes the entire agreement of the Member with respect to the subject matter hereof. In the event of a direct conflict between the provisions of this Agreement and (a) any provision of the Certificate of Formation, or (b) any mandatory, non-waivable provision of the Act, such provision of the Certificate of Formation or the Act shall control. If any provision of the Act provides that it may be varied or superseded in the limited liability company agreement (or otherwise by agreement of the members or managers of a limited liability company), such provision shall be deemed superseded and waived in its entirety if this Agreement contains a provision addressing the same issue or subject matter.
