(TSX:  PRE; BVC:  PREC) announced today that it has successfully closed an offering of U.S.$1 billion in senior unsecured notes at a rate of 5.125% due 2023 (the "Notes").  The net proceeds from the sale of the Notes will be used by the Company to repay outstanding short-term indebtedness and for general corporate purposes.  The Notes have been assigned ratings of BB+ by Fitch Ratings and Standard & Poor's Corporation, and Ba2 by Moody's Investors Services.  The Notes were placed through a syndicate of underwriters, including Merrill Lynch, Pierce, Fenner & Smith Incorporated, Citigroup Global Markets Inc., Credit Suisse Securities (USA) LLC and Itau BBA USA Securities, Inc., as Joint Lead Managers and Bookrunners. The Notes were placed with Qualified Institutional Buyers in the United States pursuant to the registration exemptions provided by Rule 144A of the Securities Act of 1933, and on a private placement basis in certain provinces of Canada, as well as internationally as permitted by applicable securities laws in such jurisdictions.

Ronald Pantin, the Company's Chief Executive Officer, commented:  "We are extremely pleased with the success of this offering.  The order book for the offering was over seven times oversubscribed and there was broad participation from over 330 investors in the United States, Canada, Latin America (including Colombia), Europe and Asia, thereby demonstrating the confidence of international investors in Pacific Rubiales and its business strategy."

The Company has applied to the Luxembourg Stock Exchange to admit the Notes for listing on the Official List of the Luxembourg Stock Exchange and to trade the Notes on its Euro MTF market.  The securities have not been and will not be registered under the United States Securities Act of 1933, as amended, or any state securities laws, and may not be offered or sold in the United States or to, or for the account or benefit of, U.S. persons absent registration or an applicable exemption from registration requirements.  This news release does not constitute an offer to sell or a solicitation of an offer to sell any of the securities.  In Canada, the Notes were only offered to accredited investors (as defined under applicable securities laws).  None of the Notes were offered to undetermined Colombian residents or to more than 100 determined Colombian residents.

In connection with the offering of the Notes, the Company obtained approval from Peru's Banking, Insurance and Pension Funds Superintendent for registration of the Notes in Peru.  With this registration, the Notes are eligible to be purchased by Peru's pension funds.
