LAW AND DISPUTE RESOLUTION

11.1 Governing Law

Page 19 of 32

--------------------------------------------------------------------------------

The substantive law of Colombia, exclusive of any conflicts of laws principles
that could require the application of any other law, shall govern this Agreement
for all purposes, including the resolution of disputes between or among Parties.

11.2 Dispute Resolution

The Parties shall first attempt to resolve any dispute, controversy, or claim
arising out of or relating to this Agreement, or the breach, termination, or
invalidity thereof through friendly consultations. If the dispute is not
resolved in this manner within thirty (30) days after commencement of
discussions, then either Party may submit the dispute to final and binding
arbitration. The tribunal shall be formed by three (3) arbitrators, all chosen
by the mutual agreement of the Parties. The arbitrators should be duly licensed
to practice law in Colombia with more than five (5) years experience in the oil
& gas industry, and fully bilingual in the English and Spanish languages. If no
agreement is reached within one (1) month counted as from the date on which any
of the Parties expresses its intention to submit the dispute to arbitration,
then arbitrators shall be appointed by drawing lots from the list of arbitrators
of the Arbitration Centre of Bogotá Chamber of Commerce Bogotá. The venue shall
be the city of Bogotá. The language of the arbitration procedure shall be the
Spanish language. The arbitral award shall be final and binding upon de Parties
and the parties agree to be bound thereby and to act accordingly. The costs of
arbitration and the costs of enforcing the arbitral award (including witness
expenses and attorneys' fees) shall be borne by the losing Party, unless
otherwise determined by the arbitral award. When any dispute occurs and when any
dispute is under arbitration, except for the matters under dispute, the parties
shall continue to exercise their remaining respective rights and fulfill their
remaining obligations under this Agreement to the extent possible under the
circumstances.

ARTICLE 12

FORCE MAJEURE

If as a result of Force Majeure, any Party is rendered unable, wholly or in
part, to carry out its obligations under this Agreement, other than the
obligation to pay any amounts due, then the obligations of the Party giving such
notice, so far as and to the extent that the obligations are affected by such
Force Majeure, shall be suspended during the continuance of any inability so
caused and for such reasonable period thereafter as may be necessary for the
Party to put itself in the same position that it occupied prior to the Force
Majeure, but for no longer period. The Party claiming Force Majeure shall notify
the other Parties of the Force

Page 20 of 32

--------------------------------------------------------------------------------

shall keep all Parties informed of all significant developments. Such notice

the period of time, which the Party will probably require to remedy the Force
Majeure. The affected Party shall use all reasonable diligence to remove or
overcome the Force Majeure situation as quickly as possible in a commercially
reasonable manner but shall not be obligated to settle any labor dispute except
on terms acceptable to it. All such disputes shall be handled within the sole
discretion of the affected Party. For the purposes of this Agreement, “Force
