Pacific Rubiales Announces Credit Approvals for Additional US$50 Million Commitments Towards Senior Secured Revolving Credit Facility
Jun 3, 2009

    TORONTO, June 3 /CNW/ - Pacific Rubiales Energy Corp. (TSX: PRE)
announced today that it has received credit approvals for additional
commitments totaling US$50 million from Banco de Bogota and Banco de
Occidente, with a participation of US$25 million each, towards a previously
announced senior secured revolving credit facility of up to US$250 million.
This brings total commitments offered by the various lenders in respect of the
facility to US$280 million. As the facility is currently subject to a
borrowing base limit of US$250 million, the company and the lenders involved
in the facility are discussing the manner in which to best accommodate
commitments from these additional lenders. Subject to the completion of such
discussions and the required documentation, the company expects to close on
these additional commitments on or about June 12, 2009. The company will only
utilize that portion of the facility which it needs to meet its 2009 capital
expenditure budget.
    The facility is a senior secured revolving credit facility maturing on
June 30, 2013, and bears interest at LIBOR plus 5.50%. The company will pay
commitment fees of 1.50% on the unutilized portion of any outstanding
commitments under the facility. Subject to customary acceleration events set
out in the credit agreement executed among the parties, or unless terminated
earlier by the company without penalty, repayment of outstanding principal on
the facility will be made in equal quarterly installments following the second
anniversary of the closing date.
    The company is being advised on the financing by Endeavour Financial
International Corporation.

    Pacific Rubiales, a Canadian-based company and producer of natural gas

operator which operates the Rubiales and Piriri oil fields in the Llanos Basin
in association with Ecopetrol S.A., the Colombian national oil company. The
company is focused on identifying opportunities primarily within the eastern
Llanos Basin of Colombia as well as in other areas in Colombia and northern
Peru. Pacific Rubiales has a current net production of approximately 34,000
barrels of oil equivalent per day, with working interests in 34 blocks in
Colombia and Peru.
