TORONTO, Dec. 14 /CNW/ - Pacific Rubiales Energy Corp. (TSX: PRE) is pleased to announce that its early exercise warrant transaction was approved by an overwhelming majority of the votes cast at meetings of its shareholders and warrantholders held today. The supplemental warrant indenture relating to the same, as approved by warrantholders, has been entered into between the company and Equity Transfer & Trust Company (the "Warrant Agent").

Mr. Ronald Pantin, Chief Executive Officer, commented: "We are extremely pleased with the outcome of today's security holder meetings. As previously announced, the proceeds from the early exercise will go towards our planned capital needs and meet our growth strategy."

The 30-day period for the early exercise of the company's publicly-traded warrants will commence at 9:00 a.m. (Eastern time) on Tuesday, December 15, 2009 and will expire at 5:00 p.m. (Eastern time) on Wednesday, January 13, 2010 (the "Early Exercise Period").

Registered holders of warrants are encouraged to exercise their warrants in accordance with the procedures set forth in the notice to warrantholders (the "Warrantholder Notice") to be sent to registered warrantholders and in the form attached as Exhibit I to Schedule "A" of the management information circular for the Extraordinary Meeting of warrantholders dated November 16, 2009 (the "Circular") as soon as possible and, in any event, prior to 5:00 p.m. (Eastern time) on Wednesday, January 13, 2010 in order to acquire one common share of the company per warrant at the exercise price of $6.30 rather than $7.80 (except in limited circumstances applicable to U.S. warrantholders as set out in the Warrantholder Notice and the Circular).

Non-registered holders of warrants, whose warrants are registered in the name of a brokerage firm, bank or trust company or other intermediary, should contact their intermediaries for instructions on how to exercise their warrants.

More information regarding the procedure for exercise of the warrants during the Early Exercise Period and the automatic exchange of warrants upon expiry of the Early Exercise Period, if applicable, is contained in the Warrantholder Notice and the Circular.

U.S. Warrantholders

The common shares to be issued pursuant to the exercise or exchange of the Warrants, as the case may be, have not been and will not be registered under the U.S. Securities Act or any state securities laws and may not be offered or sold within the United States or to, or for the account or benefit of, U.S. Persons unless registered under the U.S. Securities Act and any applicable state securities laws or an exemption therefrom is available. A U.S. Warrantholder may not exercise Warrants during the Early Exercise Period or otherwise, or exchange warrants pursuant to the Warrant Exchange, unless such Person provides to the Company either (i) a written certification that the holder is an "Institutional Accredited Investor" (an "Accredited Investor", as defined in Rule 501(a) of Regulation D under the U.S. Securities Act, that satisfies the requirements of Rule 501(a)(1), (2), (3) or (7)) and delivers the subscription form and representation letter as required under section 3.7 of the Warrant Indenture (the "U.S. Certification") to the Company by January 13, 2010 in order for such U.S. Warrantholder to exercise its Warrants and receive common shares or must deliver the representation letter required by the Warrant Indenture by January 13, 2010 to have its warrants exchanged for the Exchange Payment and Exchange Shares, or (ii) a written opinion of counsel of recognized standing in form and substance satisfactory to the Company to the effect that an exception from the registration requirements of the U.S. Securities Act and applicable state securities laws is available for the issuance of the common shares issuable on exercise or exchange of the warrants. Any U.S. Warrantholder who does not comply with such requirements will not be permitted to exercise or exchange their warrants and receive common shares or receive the Exchange Payments and Exchange Shares, respectively, and their warrants will remain outstanding following the completion of the transactions.

No warrants owned by a warrantholder (A) who is in the United States, or (B) who is a U.S. Person (as defined in Regulation S promulgated under the United States Securities Act or 1933, as amended) or who holds a warrant for the account or benefit of a U.S. Person or a person in the United States may be exercised through the Clearing and Depository Services Inc. ("CDS") and no common shares will be exchanged for warrants beneficially owned by such persons in CDS. All warrants owned by such warrantholders must be immediately withdrawn from CDS.

GMP Securities L.P. and RBC Dominion Securities Inc. are acting as financial advisors to the Company with respect to the transaction.

Pacific Rubiales, a Canadian-based company and producer of natural gas and heavy crude oil, owns 100 percent of Meta Petroleum Corp., a Colombian oil operator which operates the Quifa block 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 49,500 barrels of oil equivalent per day (after royalties), with working interests in 32 blocks in Colombia and Peru.

Information in this press release expressed in barrels of oil equivalent (boes) is derived by converting natural gas to oil in the ratio of six thousand cubic feet (mcf) of natural gas to one barrel (bbl) of oil. 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.
