Pacific Rubiales Announces Closing of US$180 Million in Initial Commitments as Part of up to US$250 Million Senior Secured Revolving Credit Facility
May 5, 2009

    TORONTO, May 5 /CNW/ - Pacific Rubiales Energy Corp. (TSX: PRE) is
pleased to announce that it has closed on initial commitments totaling US$180
million under a previously announced senior secured revolving credit facility
of up to US$250 million. The facility consists of US$50 million commitments
from each of BNP Paribas, Calyon and Banco Davivienda S.A. and US$30 million
from West LB A.G., each a lead arranger for the facility. The company will
proceed with initial drawdown under the facility in the coming days.
    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 facility is subject to a borrowing base and secured by certain assets
of the company's subsidiaries operating in Colombia. The initial borrowing
base was determined by the lenders at US$250 million but will be subject to
re-determination semi-annually on April 1 and October 1 of each year; both the
company and the lenders have discretion to request limited additional
re-determinations. The company and BNP Paribas, the global coordinator for the
facility, are currently involved in advanced discussions with additional local
Colombian and international lenders to obtain further commitments up to the
amount of the current borrowing base.
    The company expects to use the proceeds from the facility for the
development of its oil infrastructure (including costs of drilling, oil
dehydration and water treatment) to increase the production capacity of the
Rubiales and Piriri fields up to 100,000 gross barrels of oil per day by the
end of 2009, as well as for general working capital purposes and the repayment
of short-term debt, subject to certain restrictions set out in the credit
    The availability of the facility allows the company to maintain its
originally budgeted capital expenditure plan for 2009, thus paving the way for
further growth in production and in the previously announced exploration
    The company is being advised on the financing by Endeavour Financial
International Corporation.

    Pacific Rubiales is a Canadian-listed producer of oil and natural gas.
The company is the largest independent oil and gas exploration and production
company in Colombia. Pacific Rubiales owns 100 percent of Meta Petroleum
Limited, which operates the Rubiales and Piriri oil fields in Colombia's
Llanos Basin in association with Ecopetrol S.A., the Colombian national oil
company, as well as Pacific Stratus Energy and Kappa Energy Holdings.
    The company is focused on identifying growth opportunities particularly
within the Eastern Llanos Basin as well as in other areas in Colombia and
northern Peru. The company has a robust and growing reserve base, and is
maximizing future production prospects through its exploration activities.
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
    Boe may be misleading, particularly if used in isolation. A boe
conversion ratio of 6 mcf:1 bbl is based on an energy equivalency conversion
method primarily applicable at the burner tip and does not represent a value
equivalency at the wellhead.
