Dear Sir:

Re: Farmout Agreement – Acadia Prospect, Province of
Alberta

     We refer to the agreement dated
June 30, 2005 (the “June 30th Agreement”) between 1048136 Alberta
Ltd. (“1048136”) and Cascade Energy, Inc. (“Cascade”). It is agreed that the
June 30th Agreement did not adequately set forth the contractual
intentions of the parties since the June 30th Agreement contemplated
that Cascade would be entitled to a 21% working interest in only Section
16 of the Farmout Lands by paying 1048136’s future share of costs attributable
to Section 16. The parties acknowledge and agree that the mutual intention was
that Cascade would earn a 21% working interest Section 16 of the Farmout Lands,
as well as a 49% working interest in the three other pre-selected sections of
the Farmout Lands earned by 1048136 as a result of 1048136 completing one
well on Section 16. It should be noted that the defined terms used in the June
30th Agreement have the same meanings when used herein.

     It is agreed that, for good and
valuable consideration, the receipt and sufficiency whereof are hereby
acknowledged, the June 30th Agreement is hereby amended by striking
the following paragraph:

     “Cascade shall assume all payment
obligations of 1048136 or reverting to 1048136 with respect to the ongoing
development of 1048136’s interest in Section 16 of the Farmin Lands and shall be
entitled to 21% of all benefits thereby accruing from Section 16, subject to
royalties reserved by the Acadia Farmout and Option Agreement and the Vega
Participation Agreement. In the event of a failure by Cascade to fund the
required portion of a given development program, Casacade shall suffer dilution
in proportion to the amount that went unfunded by Cascade. In this regard,
1048136’s determination shall be final and binding on Cascade.”

and substituting the following paragraph therefor:

     “Cascade shall assume all payment
obligations of 1048136 or reverting to 1048136 with respect to the ongoing
development of 1048136’s interest in Section 16 of the Farmin Lands and shall be
entitled to 21% of all benefits thereby accruing from Section 16, subject to
royalties reserved by the Acadia Farmout and Option Agreement, and the Vega
Participation Agreement. In addition, Cascade shall earn 49% of 1048136’s
interest in the three other sections of the Farmout Lands which have been earned
by 1048136 in accordance with the provisions of the Acadia Farmout and Option
Agreement (as assumed by 1048136 through the Vega Participation Agreement),
subject to royalties reserved by the Acadia Farmout and Option Agreement, and
the Vega Participation Agreement. In the event of a failure by Cascade to fund
the required portion of a given development program, Casacade shall suffer
dilution in proportion to the amount that went unfunded by Cascade. In this
regard, 1048136’s determination shall be final and binding on Cascade.”

     In all other respects the June
30th Agreement remains unaltered and in full force and effect.

This Agreement may be executed in counterparts and by
facsimile.

IN WITNESS WHEREOF the parties hereto have caused this
Agreement to be executed as of the day and year first written above.
