MARKED AT THE APPROPRIATE PLACE WITH TWO ASTERISKS (**).

 

AMENDMENT TO GAS PROCESSING AGREEMENT

 

                This Amendment to Gas Processing Agreement (“Amendment”) is made
and entered into this 11th day of December, 2007, by and between Markwest
Javelina Company (“Processor”) and CITGO Refining and Chemicals Company, L.P.
(“Supplier”).

 

RECITALS

 

                A.            Processor and Supplier are parties to that certain
Gas Processing Agreement made and entered into effective November 1, 2007 (the
“Gas Processing Agreement”).

 

                B.            Processor and Supplier desire to enter into this
Amendment to correct and clarify certain inadvertent mutual mistakes and
omissions as contained in the Gas Processing Agreement executed by the parties.

 

                NOW, THEREFORE, in consideration of the mutual covenants and
agreements contained herein, the parties agree as follows:

 

                1.             Section 10.1 of the Gas Processing Agreement is
hereby amended to delete the date “July 1, 2007” and replace it with the date
“November 1, 2007.”

 

                2.             The Gas Processing Agreement is hereby amended by
deleting Exhibit B attached thereto and replacing it with the complete Exhibit B
attached to this Amendment.

 

                3.             Except for the foregoing, all other terms and
provisions of the Gas Processing Agreement shall remain in full force and
effect.

 

                4.             This Amendment may be executed in counterparts,
each of which shall be deemed an original but which together shall constitute
one and the same instrument.

 

                IN WITNESS WHEREOF, this Amendment is executed effective by the
parties as of the date hereof.
