Cautionary Note Concerning Forward-Looking Statements

This press release contains forward-looking statements. All statements,
other than statements of historical fact, that address activities,
events or developments that the Company believes, expects or
anticipates will or may occur in the future (including, without
limitation, statements regarding estimates and/or assumptions in
respect of production, revenue, cash flow and costs, reserve and
resource estimates, potential resources and reserves and the Company’s
exploration and development plans and objectives) are forward-looking
statements. These forward-looking statements reflect the current
expectations or beliefs of the Company based on information currently
available to the Company. Forward-looking statements are subject to a
number of risks and uncertainties that may cause the actual results of
the Company to differ materially from those discussed in the
forward-looking statements, and even if such actual results are
realized or substantially realized, there can be no assurance that they
will have the expected consequences to, or effects on, the Company.
Factors that could cause actual results or events to differ materially
from current expectations include, among other things: uncertainty of
estimates of capital and operating costs, production estimates and
estimated economic return; the possibility that actual circumstances
will differ from the estimates and assumptions; failure to establish
estimated resources or reserves; fluctuations in petroleum prices and
currency exchange rates; inflation; changes in equity markets;
political developments in Colombia, Peru, Guatemala, Brazil, Papua New
Guinea or Guyana; changes to regulations affecting the Company’s
activities; uncertainties relating to the availability and costs of
financing needed in the future; the uncertainties involved in
interpreting drilling results and other geological data; the impact of
environmental, aboriginal or other claims and the delays such claims
may cause in the expected development plans of the Company and the
other risks disclosed under the heading “Risk Factors” and elsewhere in
the Company’s annual information form dated March 13, 2013 filed on
SEDAR at www.sedar.com. Any forward-looking statement speaks only as of the date on which it
is made and, except as may be required by applicable securities laws,
the Company disclaims any intent or obligation to update any
forward-looking statement, whether as a result of new information,
future events or results or otherwise. Although the Company believes
that the assumptions inherent in the forward-looking statements are
reasonable, forward-looking statements are not guarantees of future
performance and accordingly undue reliance should not be put on such
statements due to the inherent uncertainty therein.

In addition, reported production levels may not be reflective of
sustainable production rates and future production rates may differ
materially from the production rates reflected in this press release
due to, among other factors, difficulties or interruptions encountered
