(c)        Subject to Section 6.6(b), each Party agrees that it shall bring any
action or proceeding in respect of any claim arising out of or related to this
Agreement, whether in tort or contract or at law or in equity, exclusively in
any federal or state courts located in Delaware and (i) irrevocably submits to
the exclusive jurisdiction of such courts, (ii) waives any objection to laying
venue in any such action or proceeding in such courts, (iii) waives any
objection that such courts are an inconvenient forum or do not have jurisdiction
over it and (iv) agrees that, to the fullest extent permitted by law, service of
process upon it may be effected by mailing a copy thereof by registered or
certified mail (or any substantially similar form of mail), postage prepaid, to
it at its address specified in Section 6.9. The foregoing consents to
jurisdiction and service of process shall not constitute general consents to
service of process in the State of Delaware for any purpose except as provided
herein and shall not be deemed to confer rights on any person other than the
Parties.

6.7        Severability. If any of the provisions of this Agreement are held by
any court of competent jurisdiction to contravene, or to be invalid under, the
laws of any political body having jurisdiction over the subject matter hereof,
such contravention or invalidity shall not invalidate the entire Agreement.
Instead, this Agreement shall be construed as if it did not contain the
particular provision or provisions held to be invalid and an equitable
adjustment shall be made and necessary provision added so as to give effect to
the intention of the Parties as expressed in this Agreement at the time of
execution of this Agreement.

6.8        Amendment or Modification. This Agreement may be amended or modified
from time to time only by the written agreement of all the Parties. Each such
instrument shall be reduced to writing and shall be designated on its face as an
amendment to this Agreement. Notwithstanding anything in the foregoing to the
contrary, any amendment executed by the Partnership or any of its subsidiaries
shall not be effective unless and until the execution of such amendment has been
approved by the conflicts committee of the General Partner’s board of directors.

6.9        Notices. All notices, requests and other communications required or
permitted hereunder shall be in writing and shall be deemed duly given or
delivered (i) when delivered personally, (ii) if transmitted by facsimile when
confirmation of transmission is received or by email when receipt of such email
is acknowledged by return email, (iii) if sent by registered or certified mail,
postage prepaid, return receipt requested, on the third business day after
mailing or (iv) if sent by private courier when received; and shall be addressed
as follows:
