(a)If taxes and related interest, penalties or additions to tax are paid by the Partnership on behalf of all or less than all the Partners or former Partners (including, without limitation, any payment by the Partnership of an Imputed Underpayment), the General Partner may treat such payment as a distribution of cash to such Partners, treat such payment as a general expense of the Partnership, or, in the case of an Imputed Underpayment, require that persons who were Partners of the Partnership in the taxable year to which the payment relates (including former Partners) indemnify the Partnership upon request for their allocable share of that payment, in each case as determined appropriate under the circumstances by the General Partner.  The amount of any such indemnification obligation of, or deemed distribution of cash to, a Partner or former Partner in respect of an Imputed Underpayment shall be reduced to the extent

that the Partnership receives a reduction in the amount of the Imputed Underpayment which, in the determination of the General Partner, is attributable to actions taken by, the tax status or attributes of, or tax information provided by or attributable to, such Partner or former Partner pursuant to or described in Section 6225(c) of the Code (as amended by the BBA).

(b)Notwithstanding any other provision of this Agreement, the General Partner is authorized to take any action that may be required to cause the Partnership and other Group Members to comply with any withholding requirements established under the Code or any other federal, state or local law including pursuant to Sections 1441, 1442, 1445 and 1446 of the Code.

B. Agreement in Effect.  Except as hereby amended, the Partnership Agreement shall remain in full force and effect.

C. Applicable Law.  This Amendment shall be construed in accordance with and governed by the laws of the State of Delaware, without regard to the principles of conflicts of laws.

D. Severability.  Each provision of this Amendment 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 Amendment that are valid, enforceable and legal.
