RE: PMLP Contract: 2585-1013

Effective on and after September 1, 2009, please amend the subject contract by
deleting the "Price" clause and inserting the "Price" clause as follows:

PRICE:
For the crude oil sold and delivered hereunder, PMLP agrees to pay a price per
barrel which shall be calculated as follows:

 
a.
Determine arithmetic average of the daily settlement price for the "Light Sweet
crude Oil" prompt month contract reported by the New York Mercantile Exchange
(NYMEC) from the first day of the delivery month through the last day of the
delivery month, including weekends and U.S. holidays with the previous day's
settlement price applying to weekends and U.S. holidays.

 
b.
To the number determined in the foregoing subparagraph (a.), add the arithmetic
average of the daily settlement price for the crude contract reported by the
NYMEX from the day the delivery month becomes the prompt trading month through
the last day of the trading for the delivery month, market open quotes only,
less the average of the daily settlement price for the second month NYMEX crude
contract trading over the same period, times a percentage calculated from the
number of days starting with the first day of the delivery month and ending with
the day preceding the first trade day after the NYMEX crude contract expiration
date during the delivery month, divided by the number of days in the delivery
month.

 
c.
To the number determined in the subparagraph (a. and b.) above, add the
arithmetic average of the daily settlement price for the crude contract reported
by the NYMEX from the day the delivery month becomes the prompt trading month
through the last day of trading for the delivery month, market open quotes only,
less the average of the daily settlement price for the third month NYMEX crude
contract trading over the same period, times a percentage calculated from the
number of days starting with first trade day after the NYMEX crude contract
expiration date during the delivery month and ending with the last day of the
delivery month, divided by the number of days in the delivery month.

 
d.
To the number determined in the foregoing subparagraph (c.) add the average of
the daily high and low quotes for WTI (Midland) and subtract the average of the
daily high and low quotes for WTI, (Cushing) for the month of delivery in
Platt's Crude Oil Market Wire "America's Crude Oil Assessments" based on pricing
assessed for the days the U.S. crude oil market is open (weekends and U.S.
holidays excluded) during the period beginning with the 26th day of the month
that is two (2) months prior to delivery through and including the 25th day of
the month that is immediately prior to the month of delivery, provided, however,
that if the first day of the period falls on a day which the U.S. crude oil
market is closed, the period shall begin on the first trading day thereafter,
and if the last day of the period falls on a day on which the U. S. crude oil
market is closed, the period shall end on the last trading day prior thereto.

 
e.
To the number determined in the forgoing subparagraph (d.), subtract the net of
the following: (Sum of the Midland WTS differential minus Midland WTI
Differential divided by 14). The number determined pursuant to this subparagraph
(e.) and subparagraphs (a.), (b.), (c.) and (d.) shall be the base price per
barrel of crude oil. (X1585)

 
f.
To the number determined pursuant to subparagraphs (a.) through (e.), subtract
the amount indicated on Exhibit "A", attached hereto.
