</div>
<div align="left" style="font-size: 10pt; margin-top: 6pt">     During April 2011, we agreed to acquire from Williams an additional 24.5 percent interest in
Gulfstream in exchange for aggregate consideration of $297 million of cash, 632,584 of our limited
partner units, and an increase in the capital account of our general partner to allow it to
maintain its 2 percent general partner interest. We expect to fund the cash consideration for this
transaction through our credit facility.
Since the additional 24.5 percent interest was acquired from an entity under the common control of Williams,
it will be recorded at Williams’ historical book value which was approximately $185 million at March 31, 2011.
The transaction is expected to close during the second
quarter 2011.
