as of the effective time of the Merger:
WAIVER AND AMENDMENTS
1.
Waiver of Partnership Change of Control; Section 9.4. For purposes of the
Omnibus Agreement, the Original Parties agree that a Partnership Change of
Control shall not be deemed to occur unless and until MPC no longer directly or
indirectly controls the general partner of Partnership, and the Original Parties
hereby waive their rights, if any, to terminate the Omnibus Agreement under
Section 9.4 as a result of the completion of the transactions contemplated by
the Merger Agreement. This waiver given by the Original Parties herein shall be
effective only in connection with the consummation of the transactions
contemplated by the Merger Agreement and shall not be construed as a bar or
waiver of any other right or remedy or of any subsequent right or remedy of the
same kind on any other occasion under the Omnibus Agreement.

2.
New Parties. The preamble to the Omnibus Agreement is hereby amended to add MPC
and New General Partner as parties to the Omnibus Agreement, and MPC and New
General Partner, by their signatures below, agree to be bound by, and subject
to, all of the covenants, terms and conditions of the Omnibus Agreement as
though an original party thereto.

3.
Replacement of General Partner. In accordance with the Merger Agreement and in
satisfaction of Section 8 of the Support Agreement, the General Partner is
hereby replaced by the New General Partner in the Omnibus Agreement, and any and
all references in the Omnibus Agreement to the General Partner shall be deemed
references to the New General Partner as though New General Partner were an
original party thereto.

4.
Definition of Partnership Change of Control. The definition of “Partnership
Change of Control” is hereby amended and restated as follows:

“Partnership Change of Control” means MPC ceases to Control the general partner
of the Partnership.”

pertaining to the subject matter hereof, and supersedes all prior agreements,
understandings, negotiations and discussions, whether oral or written, of the
Parties pertaining to the subject matter hereof.
c.    This Second Amendment may be executed in counterparts, each of which shall
be deemed an original instrument, but all such counterparts together shall
constitute but one agreement. Either Party's delivery of an executed counterpart

Amendment in any situation or jurisdiction shall not affect the validity or
enforceability of the other terms or provisions hereof or the validity or
enforceability of the offending term or provision in any other situation or in
any other jurisdiction and the remaining terms and provisions shall remain in
full force and effect, unless doing so would result in an interpretation of this
Second Amendment that is manifestly unjust.
