Item 1.01 Entry into a Material Definitive Agreement.

      On February 15, 2005, Teton Petroleum Company ("we" or the "company")
signed a membership interest purchase agreement with PGR Partners, LLC ("PGR")
whereby we acquired 25% of the membership interest in Piceance Gas Resources,
LLC, a Colorado limited liability company ("Piceance LLC"). Piceance LLC owns
certain oil and gas rights and leasehold assets covering approximately 6,300
acres in the Piceance Basin in Western Colorado. The properties owned by
Piceance LLC carry a net revenue interest of 78.75%.

      The purchase price for the membership interest in Piceance LLC was $5.25
million in cash, the issuance of 450,000 unregistered shares of our common
stock, and the issuance of warrants to purchase 200,000 shares of our common
stock, exercisable for a period of five years at an exercise price of $2.00 per
share. We also entered into a registration rights agreement with PGR Partners
whereby we granted PGR Partners certain registration rights in connection with
the shares of our common stock and shares underlying the warrants issued as part
of the purchase price.

Item 3.02 Unregistered Sales of Equity Securities.

      As part of the consideration for the purchase of 25% of the membership
interests of Piceance LLC, on February 15, 2005, we issued to PGR Partners
450,000 unregistered shares of our common stock and warrants to purchase an
additional 200,000 shares of common stock at an exercise price of $2.00 per
share, exercisable for a period of five years. This transaction was not
registered under the Securities Act of 1933, as amended (the "Act") in reliance
on an exemption from registration under Section 4(2) of the Act based on the
limited number of purchasers, their sophistication in financial matters, and
their access to information concerning the company.
