BreitBurn Energy Partners L.P. Announces Reaffirmation of Borrowing Base at $732 Million, Unchanged From Previous Level

LOS ANGELES--(Business Wire)--
BreitBurn Energy Partners L.P. (NASDAQ:BBEP) today announced the completion of
its semi-annual borrowing base redetermination with its syndicate of lenders in
its credit facility. As a result of this process, the Partnership`s borrowing
base remains unchanged at $732 million.

Jim Jackson, BreitBurn`s Chief Financial Officer, said, "We are pleased with the
reaffirmation of our borrowing base, which was completed without modification to
any of the terms of our Credit Agreement, and acknowledge the continued support
of our bank group in this process. We have further reduced our outstanding
borrowings since July 31st and were approximately $585 million drawn on our
credit facility as of September 30th. Our ongoing commitment to debt reduction
has resulted in the pay down of more than $150 million in borrowings since year
end 2008. As we begin the 2010 planning process, our improved liquidity position
will allow us the flexibility to further accelerate capital spending to levels
that should enable us to hold production flat and subsequently re-establish
distributions when leverage has been reduced to acceptable levels."

The Partnership`s next semi-annual borrowing base redetermination is scheduled
for April 2010.
