The terms are not comprehensive and additional terms, including customary representations and warranties, will be incorporated into a formal agreement (the “Formal Agreement”) to be negotiated between the Purchaser and the Seller. The basic terms are as follows:

Purchaser: The Purchaser is a company incorporated under the laws of the State of  Nevada with its common shares registered under the Securities Exchange Act of 1934.

2)

Seller: The Seller is a company incorporated under the laws of Nevada. Prior to the completion of and depending on the structure for the purchase of the Assets, the Seller may be required to continue from the federal jurisdiction of the State of Nevada.

3)

Transaction: The Purchaser agrees to purchase that certain cultured diamond technology patent and related intellectual property (the “Assets”) from the Seller (the “Acquisition”). In consideration for the Acquisition, the Purchaser will issue to the Seller or Seller’s shareholders an aggregate of 43,850,000 shares of Purchaser’s restricted common stock (the “Consideration Shares”).  On or prior to the consummation of the Acquisition (the “Closing”), certain of the Purchaser’s shareholders will surrender for cancellation to the treasury of the Purchaser a sufficient number of shares of the Purchaser’s issued and outstanding common stock such that, upon the Closing (including those securities issuable under the Financing), the total number of issued and outstanding shares of common stock of the Purchaser will equal 73,000,000 shares on a fully-diluted basis. The Consideration Shares will constitute sixty percent (60%) of the total issued and outstanding common stock of the Purchaser at Closing.  No other class or series of capital stock of the Purchaser will exist at the Closing.  Also in consideration for the purchase of the Assets, Purchaser agrees to assume debts of the Seller in an amount not to exceed $100,000, excluding the Bridge Loan (as defined herein).  In the event an audit is required of the Assets and assumed debt, Seller will provide the same from a PCAOB qualified auditor no later than the Closing.
