Corporation (the &ldquo;Company&rdquo;) entered into an exploration and development agreement with Oppenheimer Drilling Partners,
L.P. (&ldquo;ODP&rdquo;), a New York based investment fund affiliated with Oppenheimer&nbsp;&amp; Co, Inc. ODP has made a capital
commitment of at least $10 million with the potential for a greater investment up to $30 million, if certain conditions occur,
to co-invest with the Company in its future acquisition and development of assets in the Bakken Shale formation in the Williston
Basin of North Dakota and Montana. Up to 50% of ODP&rsquo;s capital commitment may be allocated for leasehold acquisition with
the remainder available for well development. In addition, ODP paid Triangle approximately $2.7 million in exchange for 7% of the
Company&rsquo;s interest in certain oil and gas leases in an area of mutual interest (&ldquo;Station AMI&rdquo;) located in Sheridan
and Roosevelt Counties in Montana. Under the agreement, ODP has the right to participate in up to 7% of future Company leasing
activity in the Station AMI and up to 25% of future Company leasing activity in the rest of the Williston Basin.</P>

The acreage premium varies depending upon the level of lease acquisition costs. ODP will also bear 10% of all of the Company&rsquo;s
brokerage costs in the region. The agreement may be terminated by either party after three years.</P>
