Plains All American Pipeline to Acquire Remaining 50% Interest in Natural Gas Storage JV

Comments on Intent to Recommend Distribution Increase
HOUSTON--(Business Wire)--
Plains All American Pipeline, L.P. (NYSE:PAA) and Vulcan Capital today announced
that they have executed definitive agreements under which a subsidiary of PAA
will acquire Vulcan Capital`s 50% indirect interest in PAA Natural Gas Storage,
LLC (PNGS). The aggregate purchase price of $220 million consists of $90 million
cash, 1.9 million PAA common units valued at $90 million, and deferred
contingent cash consideration of up to $40 million. The contingent consideration
is subject to achievement of certain events and performance milestones expected
to occur over the next several years. The transaction is expected to close on
September 3, 2009.

As a result of the transaction, PAA will own 100% of the natural gas storage
business and related operating entities, which will be accounted for on a
consolidated basis. The Partnership has historically accounted for its 50%
indirect interest in PNGS under the equity method. At closing, PAA will repay
the joint venture`s outstanding project finance debt using joint venture cash
and borrowings under its revolving credit facility. As of June 30, 2009, the
joint venture had approximately $450 million of debt and approximately $52
million of cash.

"We are extremely pleased to announce this transaction and are excited about the
near-term and long-term potential of the natural gas storage business," said
Greg L. Armstrong, CEO of PAA. "This transaction provides economic returns
solidly in excess of our weighted average cost of capital and will result in
immediate accretion to the Partnership."

"Increasing our interest to 100% will enhance our strategic flexibility with
respect to future organic growth and acquisitions, and also increase the
visibility of the value that has already been created," said Armstrong.
"Notably, the cash-flow stream of our natural gas storage business is
essentially 100% fee-based, with currently available storage capacity
substantially committed under contracts ranging up to ten years in duration.
Moreover, the cash-flow profile is expected to increase steadily over the next
several years as we continue to expand the storage capacity through our
development activities at our Pine Prairie facility."

Geoff McKay, a Managing Director at Vulcan Capital, said, "We have enjoyed
working with the entire PAA team over the last four years to build value
together at PNGS. Through our significant equity position in PAA, we will
continue to be a meaningful participant in the growth of this and PAA`s other
businesses, and we look forward to continuing to support PAA`s future success."

The transaction was approved by the board of directors of the general partner of
PAA and by its conflicts committee. The conflicts committee, which is comprised
entirely of independent directors, received a fairness opinion from Simmons &
Company International with respect to the consideration paid by PAA in this
transaction.

PAA management intends to recommend to its board of directors an increase in the
Partnership`s quarterly distribution level to $0.92 per unit, or $3.68 per unit
on an annualized basis, effective with the November 2009 distribution, subject
to adverse developments in the economic and financial markets, or other events
that would make such recommendation inappropriate. To enhance PAA`s distribution
coverage ratio over the next 24 months as cash flows ramp-up from expansion
activities, PAA`s general partner has agreed to reduce its incentive
distributions by an aggregate of $8 million over the next two years - $1.25
million per quarter for the first four quarters and $0.75 million per quarter
for the next four quarters. The IDR reduction will become effective with the
planned November 2009 distribution increase.
