                                                         Agreement dated 11/7/96

                                                         Weld County, Colorado

Gentlemen:

     Due to the drop in oil and gas prices, Prima Oil & Gas Company decided to

suspend drilling operations until 2002.   We did not feel it was prudent to

develop the reserves at the low prices. Therefore, we respectfully request that

we extend the termination date of our Farmout/Farmout Option Contract until the

end of 2002.
