SECTION 17. Limitation of Liability, Indemnification and Exculpation.

(a) Limitation of Liability. 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

no Member or Manager shall be obligated personally for any such debt, obligation or liability of the Company solely by reason of being a Member or Manager.

(b) Indemnification. The Company shall indemnify, in accordance with and to the full extent now or hereafter permitted by law, any Person who was 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 or investigative (including, without limitation, an action by or in the right of the Company) by reason of the fact that such Person is or was a Member, Manager or officer of the Company (and the Company may so indemnify a Person by reason of the fact that such Person is or was an employee or agent of the Company, or is or was serving at the request of the Company as a director, trustee, member, manager, officer, employee or agent of another limited liability company, corporation, partnership, joint venture, trust or other enterprise), against any liabilities, expenses (including, without limitation, attorneys' fees and expenses and any other costs and expenses incurred in connection with defending such action, suit or proceeding), judgments, fines and amounts paid in settlement actually and reasonably incurred by such Person in connection with such action, suit or proceeding if such Person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the Company, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption (a) that the Person did not act in good faith and in a manner which he or she reasonably believed to be in or not opposed to the best interests of the Company, or (b) with respect to any criminal action or proceeding, that the Person had reasonable cause to believe that his or her conduct was unlawful.

(c) Advancement of Expenses. Expenses (including, without limitation, attorneys' fees and expenses) incurred by a Member, Manager or officer of the Company in defending a civil, criminal, administrative or investigative action, suit or proceeding may 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 the Member, Manager or officer to repay such amount if it shall ultimately be determined that such Member, Manager or officer is not entitled to be indemnified by the Company under this Section 17 or under any other contract or agreement between such Member, Manager or officer and the Company. Such expenses (including attorneys' fees) incurred by employees or agents of the Company may be so paid upon the receipt of the aforesaid undertaking and such terms and conditions, if any, as the Board of Managers deems appropriate.

(d) Rights Not Exclusive. The indemnification and advancement of expenses provided by this Section 17 shall not be deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any agreement, vote of Members or otherwise, both as to action in such Person's official capacity and as to action in another capacity while holding such office.

(e) Insurance. The Company may purchase and maintain insurance on behalf of any Person who is or was a Member, Manager, officer, employee or agent of the Company, or is or was serving at the request of the Company as a director, trustee, member, manager, officer, employee or agent of another limited liability company, corporation, partnership, joint venture, trust or 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 such Person would be entitled to indemnity against such liability under the provisions of this Section 17.

(f) Exculpation. Notwithstanding anything to the contrary set forth in this Agreement, no Manager shall be liable to the Company or to any Member for monetary damages for any losses, claims, damages or liabilities arising from any act or omission of such Manager arising out of or in connection with this Agreement or the Company's business or affairs, unless, and then only to the

extent that, such act or omission (1) is attributable to such Manager's fraud, bad faith, wilful misconduct or gross negligence or (2) was clearly outside the scope of authority granted to such Manager under this Agreement.

(g) Successors. The indemnification and advancement of expenses provided by, or granted pursuant to, this Section 17 shall continue as to a Person who has ceased to be a director, trustee, member, manager, officer, employee or agent and shall inure to the benefit of the successors, heirs, executors and administrators of such a Person.

(h) Certain References. For purposes of this Section 17, references to "the Company" shall include, in addition to the resulting business entity, any constituent business entity (including any constituent of a constituent) absorbed in a consolidation or merger, which, if its separate existence had continued, would have had power and authority to indemnify its directors, trustees, members, managers, officers, employees or agents, so that any person who is or was a director, trustee, member, manager, officer, employee or agent of such constituent business entity, or is or was serving at the request of such constituent business entity as a director, trustee, member, manager, officer, employee or agent of another limited liability company, corporation, partnership, joint venture, trust or other enterprise, shall stand in the same position under the provisions of this Section 17 with respect to the resulting or surviving business entity as he would have with respect to such constituent business entity if its separate existence had continued. In addition, for purposes of this Section 17, references to "other enterprises" shall include employee benefit plans; references to "fines" shall include any excise taxes assessed on a Person with respect to an employee benefit plan; and references to serving at the request of any business entity shall include any service as a director, trustee, member, manager, officer, employee or agent of such business entity which imposes duties on, or involves services by, such director, trustee, member, manager, officer, employee or agent with respect to an employee benefit plan, its participants, or beneficiaries.

Neither the Company nor any other Member shall have any right by virtue of this Agreement in or to any such other interests or activities or to the income or proceeds derived therefrom. A Member may transact business with the Company and, subject to applicable laws, has the same rights and obligations with respect thereto as any other Person.

SECTION 22. Taxation.

(a) Tax Elections. The Board of Managers shall not, without the unanimous consent of the Members, cause the Company to make an election to be classified as a corporation for federal or state income tax purposes. The Board of Managers shall, upon the written request of any Member benefitted thereby, cause the Company to file an election under Section 754 of the Code and the Treasury Regulations thereunder to adjust the basis of the Company assets under Section 734(b) or 743(b) of the Code and a corresponding election under the applicable sections of state and local law.

(ii) If at any time the Tax Matters Member cannot or elects not to serve as the Tax Matters Member, is removed by the Members as the Tax Matters Member or ceases to be a Member, the Majority Interest shall select another Member to be the Tax Matters Member. The Tax Matters Member, as an authorized representative of the Company, shall direct the defense of any claims made by the IRS to the extent that such claims relate to the adjustment of Company items at the Company level. The Tax Matters Member shall promptly deliver to each Member a copy of any notice of beginning of administrative proceedings or any report explaining the reasons for a proposed adjustment received from the IRS relating to or potentially resulting in an adjustment of Company items. The Tax Matters Member shall, unless the Majority Interest consents to the contrary, diligently and in good faith contest any proposed adjustment of a Company item that principally affects the Members at the administrative and judicial levels, including, if appropriate or if requested by the Majority Interest, appealing any adverse judicial decision, and shall consider in good faith any suggestions made by any Member or its counsel regarding the conduct of such administrative or judicial proceedings.

(iii) The Company shall promptly deliver to each Member a copy of all notices, communications, reports or writings of any kind with respect to income or similar taxes received from any state or local taxing authority relating to the Company that might materially and adversely affect each Member, and shall keep such Members advised of all material developments with respect to any proposed adjustment of Company items that come to its attention.
