TORONTO, Nov. 19, 2012 /PRNewswire/ – Pacific Rubiales Energy Corp. (TSX: PRE;
BVC: PREC; BOVESPA: PREB) is pleased to announce it has entered into an
arrangement agreement with C&C Energia Ltd. (TSX: CZE) whereby Pacific
Rubiales will acquire all of the common shares of C&C Energia (the “Arrangement Agreement“).

Pursuant to the Arrangement Agreement, on closing of the acquisition
each common share of C&C Energia will be exchanged for 0.3528 common
shares of Pacific Rubiales and one common share of a new exploration
company (“Newco“). The offer values C&C Energia at approximately Cdn.$7.81 per share,
representing a premium of approximately 21% to the 20-day
volume-weighted price on the Toronto Stock Exchange of C&C Energia as
at November 16, 2012. In addition, C&C Energia’s management estimates
Newco’s value to be approximately Cdn.$2.00 per share, representing a
combined value of approximately Cdn.$9.81 and a premium of
approximately 52% over the same period.

Pacific Rubiales is expected to retain a 5% equity interest in Newco.
It is anticipated that the transaction will be effected by way of a
court approved plan of arrangement (“Arrangement“).

Ronald Pantin, Chief Executive Officer of Pacific Rubiales, commented:
“We consider this to be a win-win for the shareholders of both
companies. For Pacific Rubiales shareholders, it adds production and
reserves at attractive and accretive metrics and assets whose value can
be increased through accelerated activity and transportation and
marketing synergies. For C&C Energia shareholders, it provides an
immediate premium valuation, enhanced liquidity and participation in
the growth of Colombia’s largest independent oil company with a history
of generating consistent shareholder returns. C&C Energia shareholders
will also have continued exposure to the producing assets through the
new ownership in Pacific Rubiales common shares as well as the
exploration upside provided by a well-funded Newco.”

Strategic Rationale

Pacific Rubiales believes that this is a highly strategic acquisition
and provides additional visibility to its ability and leverage to
increase production and reserves both organically and acquisitively at
attractive and competitive metrics.

The key attributes of the acquired C&C Energia assets are as follows:

• consist of four development blocks (Cravoviejo, Cachicamo, Pájaro Pinto,
  Llanos 19 blocks), which are all in the prolific Colombian Llanos
  basin;

• in close proximity to Pacific Rubiales’ existing heavy oil production
  and pipeline infrastructure, allowing for additional value captured
  through transportation and marketing efficiencies;

• 100% working interest and operatorship on all the blocks is expected to
  provide an advantageous position to drive activity and the pace of
  development;

• provide material production, additional reserves and additional free
  cash flow to Pacific Rubiales’ existing portfolio in Colombia;

• current production of approximately 11,500 bbl/d net before royalties,
  all of which is high quality and high netback light oil;

• the light oil production can be used to meet Pacific Rubiales’ growing
  requirement for diluent to mix with its heavy oil production at a lower
  cost; and

• Pacific Rubiales believes it will be able to quickly ramp up production
  on the Llanos development blocks within a 12 month period, capturing
  and accelerating value.

In addition, Pacific Rubiales and the shareholders of C&C Energia will
retain upside potential on the exploration assets through their equity
ownership of Newco. It is anticipated that Newco will acquire C&C
Energia’s interests in the Coati, Andaquies, Morpho and Putumayo-8
blocks in Colombia and receive cash from C&C Energia in the amount of
approximately U.S.$80 million, subject to working capital adjustments.

Terms of the Arrangement

The Arrangement is subject to approval by the shareholders of C&C
Energia, court approval, regulatory, stock exchange and other
approvals, and satisfaction of all other customary closing conditions.
To proceed, the Arrangement must be approved by at least 66 2/3 of C&C
Energia’s shareholders. The Arrangement is expected to close in the
first quarter of 2013.

The Arrangement Agreement also provides that C&C Energia will pay
Pacific Rubiales a non-completion fee of Cdn.$15 million in certain
circumstances and a reciprocal non-completion fee is payable by Pacific
Rubiales to C&C Energia in certain circumstances. The Arrangement
Agreement includes customary provisions, including no solicitation of
alternative transactions, right to match superior proposals and
fiduciary-out provisions.

Board of Director Recommendation and Financial Advisors

The board of directors of C&C Energia has approved the Arrangement
Agreement and has resolved to recommend that the shareholders of C&C
Energia vote in favour of the Arrangement.

Pacific Rubiales’ financial advisor is GMP Securities L.P.; its legal
advisor is Norton Rose Canada LLP in Canada and Colombia. C&C
Energia’s financial advisor is FirstEnergy Capital Corp. (“FirstEnergy“); its legal advisor is Blakes, Cassels & Graydon LLP in Canada and
Posse Herrera Ruiz in Colombia.

FirstEnergy has provided the board of directors of C&C Energia with an
opinion that, subject to its review of the final form of documentation
effecting the Arrangement, the consideration to be offered by Pacific
Rubiales to the shareholders of C&C Energia under the Arrangement is
fair, from a financial point of view, to the shareholders of C&C
Energia.

Support Agreements

The Arrangement has the support of executive officers of C&C Energia as
well as certain directors and shareholders who collectively hold
approximately 41% of the fully diluted common shares of C&C Energia.
Each of the aforementioned executive officers, directors and
shareholders has entered into support agreements in favour of the
Arrangement.
