</div>
<div align="left" style="font-size: 10pt; margin-top: 6pt">     On April 26, 2011, we signed an agreement to sell our 20% interest in West Texas LPG Pipeline
Limited Partnership (“WT LPG”) to affiliates of Atlas Pipeline Partners L.P. for $85.0 million. WT
LPG owns a 2,295-mile common-carrier pipeline system that transports natural gas liquids from
points in New Mexico and Texas to Mont
Belvieu, Texas for fractionation. Chevron Pipeline Company,
which owns the remaining 80% interest, is the
operator of WT LPG. The transaction is expected to close in the second quarter of 2011,
subject to customary closing conditions. The proceeds from the sale will be used to fund a portion
of our internal growth capital projects planned for 2011.
