(Big Cat or the Company) executed a definitive agreement with High Plains Gas, Inc. (High Plains) for the sale of 20,000,000 shares of its restricted common stock, or approximately 31.3% of the projected issued and outstanding shares, at $0.03 per share for $600,000. The purchase price of $600,000 consists of a combination of $200,000 cash and 739,180 restricted shares of High Plains valued at $400,000.
