Item 1.01 Entry into a Material Definitive Agreement.

      On December 17, 2004, Teton Petroleum Company ("we" or the "company")
purchased an option through a binding letter of intent with [*] ("[*]")
entitling the Company, if exercised, to acquire certain oil and gas leases
covering [*] acres in North America. Execution of the option is subject to the
satisfactory results of a due diligence investigation and the approval of our
board of directors.

      If the option is exercised, the purchase price for the acreage will be
approximately $[*], of which $[*] will be payable in unregistered shares of our
common stock, valued at $1.75 per share. In addition, we will issue a warrant to
[*] entitling it to purchase one share of our common stock for each two shares
of common stock issued to [*] as part of the purchase price, exercisable period
of three years at an exercise price of $1.75 per share. The cost of the option
paid to [*] was $25,000, and is nonrefundable. The purchase price for the
acreage is subject to adjustment if there are title defects or environmental
problems with any of the leases.

      In the event the option is exercised, but it is later determined that the
total acres with acceptable title and environmental conditions is less than
138,063 acres, we have the right to terminate the agreement.

      [*] will also retain an overriding royalty interest in the acreage. The
letter of intent also provides for the establishment of an Area of Mutual
Interest with [*] that will give us the right to purchase additional leases
acquired by [*] in the Area of Mutual Interest through December 31, 2007.

      We expect to close the transaction on April 15, 2005, provided that the
option is exercised and the contingencies set forth in the letter of intent are
met.

                                    SIGNATURE

      Pursuant to the requirements of the Securities Exchange Act of 1934, the
registrant has duly caused this report to be signed on its behalf by the
undersigned.
