5.2. Allocations of Net Profit and Net Loss.

(a) Subject to Section 5.2(b), Net Profit and Net Loss shall be allocated among the Members so as to reduce, proportionately, the difference between their respective Target Capital Accounts and Partially Adjusted Capital Accounts as of the end of such period, provided that no portion of Net Profit or Net Loss for any period shall be allocated to a Member, in the case of a Net Profit, whose Partially Adjusted Capital Account is greater than or equal to its Target Capital Account or, in the case of a Net Loss, whose Target Capital Account is greater than or equal to its Partially Adjusted Capital Account for such period.

(b) If (i) the Company has a Net Profit for any period and, notwithstanding the application of Section 5.2(a), the balance of any Member's Partially Adjusted Capital Account is greater than the balance of its Target Capital Account, then the Member with such excess balance shall be specially allocated items of Company expense or loss for such period (to the extent available) equal to the difference between its Partially Adjusted Capital Account and its Target Capital Account; (ii) the Company has a Net Loss for any Period and, notwithstanding the application of

Section 5.2(a), the balance of any Member's Partially Adjusted Capital Account is less than the balance of its Target Capital Account, then the Member with such deficient balance shall be specially allocated items of Company income or gain for such period (to the extent available) equal to the difference between its Partially Adjusted Capital Account and its Target Capital Account; and (iii) the Company has neither a Net Profit nor a Net Loss for any period and, notwithstanding the application of Section 5.2(a), the balance of any Member's Partially Adjusted Capital Account differs from the balance of its Target Capital Account, then the Member with an excess or deficient balance, as the case may be, shall be specially allocated items of Company expense or loss or income or gain, as the case may be, for such period (to the extent available) equal to the difference between its Partially Adjusted Capital Account and its Target Capital Account. Solely for purposes of this Section 5.2(b), Net Profit and Net Loss shall be determined by giving effect to any items of gain, income, deduction or loss specially allocated pursuant to this Section 5.2(b).

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 that the person did not act in good faith and in a manner which the person 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 reasonable cause to believe that the person's conduct was unlawful.

(b) Additional Indemnification. The Company shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the Company to procure a judgment in its favor by reason of the fact that the person is or was a member of the Board, Officer, employee or agent of the Company, or is or was serving at the request of the Company as a member of the Board, officer, employee or agent of another corporation, or of a partnership, joint venture, trust or other enterprise against expenses (including attorneys' fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the Company and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the Company unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

(c) Advance of Expenses. Expenses incurred in defending a civil or criminal action, suit or proceeding shall (in the case of any action, suit or proceeding against a member of the Board) or may (in the case of any action, suit or proceeding against an Officer, trustee, employee or agent) be paid by the Company in advance of the final disposition of such action, suit or proceeding as

authorized by the Board upon receipt of an undertaking by or on behalf of the indemnified person to repay such amount if it shall ultimately be determined that he is not entitled to be indemnified under this Article.

(d) Rights Not-Exclusive. The indemnification and other rights set forth in this Section 7.7 shall not be exclusive of any provisions with respect thereto in any other contract or agreement between the Company and any Officer, member of the Board, employee or agent of the Company.

The Board may consult with counsel, accountants, appraisers, management consultants, investment bankers and other consultants. An opinion by any such Person on a matter that the Board believes to be within such Person's professional or expert competence will be full and complete protection for any action taken or omitted by the Board in good faith based on the opinion. The Board will not be responsible for the misconduct, negligence, acts, or omissions of any such Person or of any agent or employee of the Company, the Board, or any of their Affiliates.

7.8. Special Tax Covenants.

(a) UBTI. The Company shall conduct the affairs of the Company in a manner that does not cause any of the Warburg Investors or any direct or indirect partner or member thereof, that is exempt from income taxation pursuant to Section 501 of the Code, to have any "unrelated business taxable income" ("UBTI"), including, without limitation, any "unrelated debt-financed income" (as those terms are defined in Sections 512 and 514 of the Code), or gross income attributable to a "trade or business" (within the meaning of Sections 512 and 513 of the Code) and the Company shall not take any action that will cause any such Person to have any UBTI or gross income attributable to a "trade or business." If at any time the Company becomes aware that it is reasonably likely that any such Person has incurred or will incur UBTI or gross income attributable to a "trade or business" as a result of such Person's direct or indirect interest in the Company, the Company shall promptly notify such Person of such fact in writing. If as a result of the incurrence of UBTI or gross income attributable to a "trade or business" relating to an investment or activity of the Company, the Company becomes obligated to provide notice to a Person pursuant to the preceding sentence, the Company shall promptly thereafter take whatever action may be reasonably necessary to preclude any further realization of UBTI or gross income attributable to a "trade or business" from such investment or activity. Without limiting the generality of the foregoing, the Company shall not invest in any entity that is (or would be after such investment) classified as a partnership or other pass through vehicle for federal income tax purposes, or incur indebtedness in connection with the acquisition of any Investment.
