On November 23, 2011, Mainland Resources, Inc. (the "Company") entered into an Amendment and Restatement of Lease Acquisition Agreement (the "Agreement"), dated effective as of October 1, 2011, with Sklar Exploration Company, LLC ("Sklar").

Sklar paid the remaining $530,000 (representing approximately $200 per net acre) to the Company.

The Company used the proceeds of the sale to re-pay, in part, a secured creditor of the Company.

A copy of the Agreement is included as Exhibit 10.1 hereto.
