Recitals

WHEREAS, Jesperator is engaged in the business of developing, manufacturing and selling silicon carbide material (SiC) for various applications and desires to supply C&C with SiC; and

WHEREAS, C&C manufactures and markets gemstones fabricated from SiC and desires to purchase SiC from Jesperator; and

WHEREAS, Jesperator and C&C desire to enter into an Exclusive Supply and Loan Agreement for Jesperator to supply C&C with SiC and C&C agrees to purchase SiC from Jesperator as provided herein;

NOW, THEREFORE, the parties hereto, in consideration of the foregoing premises and the covenants and undertakings herein contained, mutually agree as follows:

1. Exclusivity. During the Initial Term and any Additional Term (as defined below) of this Agreement, Jesperator (including any affiliates of Jesperator) shall not sell SiC in any form to any customer other than C&C if Jesperator has knowledge or has reason to believe that such customer, or its customers, intend to use such material for the purpose of fabricating, distributing or selling faceted jewels or gemstones. Upon termination of this Agreement pursuant to Section 4.3 hereof due to a material breach by Jesperator, Jesperator (including any affiliates of Jesperator) agrees that for the period equal to the Initial Term and the Additional Term, Jesperator shall not sell SiC to any customer if Jesperator has knowledge or has reason to believe that such customer, or its customers, intend to use such material for the purpose of fabricating, distributing or selling faceted jewels or gemstones. This condition, however, is only valid in case C&C continues to stay in the business of fabricating, distribution and selling faceted jewels or gemstones made from SiC and is only valid to the extent it is not in violation of any applicable law in Sweden or in any other relevant jurisdiction.

2. Purchase and Sale of SiC

2.1 Minimum Purchase and Sale Quantities. (a) Minimum Quantities. C&C shall purchase from Jesperator and Jesperator shall sell to C&C SiC meeting the specifications for useable material set out on Exhibit A, in the minimum quantities (“Minimum Quantities”) and at the prices set out on Exhibit B during the periods set forth therein. (b) Minimum Quantities Subject to Capacity. If and to the extent that Jesperator has the production capacity to deliver up to the minimum quantities subject to capacity set out on Exhibit B (the “Minimum Quantities Subject to Capacity”), C&C shall purchase from Jesperator and Jesperator shall sell to C&C such Minimum Quantities Subject to Capacity of SiC meeting the specifications for useable material set out on Exhibit A during the periods set forth in Exhibit B. (c) Minimum Quantities Subject to Capacity Commencing September 1, 2006. Commencing September 1, 2006, such Minimum Quantities Subject to Capacity shall, subject to Jesperator’s production capacity, be amount set forth in Exhibit B. No later than 90 days prior to the

March 7, 2007

end of each calendar quarter, Jesperator shall inform C&C of its expected production capacity of SiC meeting the specifications set forth on Exhibit A for the upcoming quarter.

2.2 Useable Material Assessment. Within 10 days of receipt of SiC from Jesperator, C&C shall grade all SiC received from Jesperator according to the specifications set out on Exhibit A. C&C shall provide regular feedback to Jesperator concerning the grading of all SiC. Upon Jesperator’s request and at Jesperator’s expense, SiC not meeting the minimum specifications for useable material shall be returned to Jesperator for analysis. All SiC delivered to C&C and not returned to Jesperator at its expense shall be the property of C&C.

3. Loan to Purchase HTCVD Reactor and Equipment.

3.1 Loan. Concurrent with the execution of this Agreement and as a condition precedent to its effectiveness, C&C shall loan to Jesperator the sum of 400,000 USD (the “Loan”), to be used and repaid by Jesperator in accordance with the terms of this Agreement. The Loan shall not bear interest.

3.2 Use of Proceeds of the Loan. Jesperator shall use the proceeds of the Loan to acquire an HTCVD Reactor (“Reactor”) and equipment to install and operate Reactor (“Equipment”). If the cost of Reactor and Equipment exceed 400,000 USD, Jesperator shall be responsible for such additional purchase price from its own funds.

3.3 Repayment of the Loan. Jesperator shall, for deliveries of SiC to C&C made after December 31, 2005, repay such portion of the Loan as a 35% deduction of the cash payments invoiced to C&C and actually paid by C&C, in the aggregate amount up to the 400,000 USD total of the Loan. Upon the termination of this Agreement (including additional terms) due to Jesperator’s breach, any portion of the Loan remaining unpaid shall be immediately due and payable to C&C. The Loan repayments described above shall be the only repayments required to be made by Jesperator.

3.4 Default in Repayment. Upon default by Jesperator in repayment of the Loan, which default exists on or following June 1, 2006 and is not cured within ninety (90) days of written notice thereof by C&C to Jesperator, C&C may declare the total unpaid balance due and payable, or may, in lieu of further repayment of the loan convert any unpaid portion of the Loan into equity in Jesperator pursuant to Section 3.5 below.

3.5 Conversion to Equity. In the event C&C elects to convert the unpaid portion of the Loan to equity pursuant to Section 3.4 above, a new selected issue of shares shall be directed to C & C by Jesperator whereby C & C shall subscribe for such shares and pay the subscription price by way of setting off in full the unpaid portion of the Loan against the issue price. The number of shares of Common Stock of Jesperator (“Common Stock”) to be issued shall be calculated according to the following formula:

X = DO 

SO CV

Where:

3.6 Restrictions on C&C’s Ownership of Equity Following Conversion of Debt. C&C shall not sell, mortgage, transfer, assign or otherwise encumber the shares issued as a result of the conversion of the Loan to Common Stock for a period of two (2) years following issuance; provided, however, that in the event Jesperator or its shareholders enters into any merger, stock or asset sale resulting in the transfer of control in Jesperator or its principal business during such period, the shares of Common Stock owned by C&C shall be entitled to participate in any such transaction equally with other shares of Common Stock. Jesperator or its designated party may, at Jesperator’s option, repurchase its Common Stock issued pursuant to Section 3.5 at any time within six months of such purchase by C&C at a price equal to the full amount of the unpaid Loan. In addition, C&C agrees that until July 1, 2008, in the event that any shareholder of Jesperator owning more than 10% of its Common Stock enters into any agreement restricting the sale or transfer of its shares in connection with a private placement or public offering of the Common Stock of Jesperator, shares of the Common Stock owned by C&C shall be subject to the same restrictions and conditions.

IN WITNESS WHEREOF, the parties have executed this Agreement by and through their duly authorized representatives.

March 7, 2007

Exhibit A

SPECIFICATIONS:

A deliverable unit is defined as a slab of 6H SiC material that is 2 or more inches in diameter cut to a thickness of 4.3mm, or as specified in a separate letter from C&C to Jesperator 30 days prior to the start of each month. The thickness of said slabs will be 3.6mm or 4.3mm or 5.2mm or 6.3mm, or different as may be agreed by both parties. The material will be graded by C&C raw material graders upon receipt by C&C and classified according to color, tone and defects. Each piece delivered by Jesperator to C&C will have an individualized serial number affixed to it. During phases 1, 2 and 3 (Exhibit B) Jesperator has an option to deliver 2” diameter products in boules, without slicing into slabs with specified thickness as stated above.

Color and Tone of acceptable material:

The acceptable color is *****, the acceptable tone is very light (“10” according to C&C current grading standards). During the phase 1 (Exhibit B), the acceptable tone is also ***** (“20” according to C&C current grading standards) or ***** (“11” according to C&C current grading standards). It is the goal that at least one (1) boule of material produced during the R&D period will be a color and tone that is lighter than the color/tone of the current master boule used by C&C. This boule will then become the color/tone master boule that future acceptable production is evaluated against.

Defects:

SiC that is deemed acceptable according to color and tone will be graded for defects. A defect is any internal inclusion that prevents the material from being used as a moissanite jewel. The defects will be measured as a percentage of the total piece of material. Reference boule ***** (C&C assigned serial number) delivered to C&C ***** contained ***** defect free material (picture attached).

Useable material will be the total gram weight of the acceptable material reduced by the percentage of defects.

Price calculation:

Grams of acceptable material X (1-defect %) = Grams of Useable Material X Price per Gram = Price

During the period February 28, 2005 to February 28, 2006, boules that are at least *****useable will be deemed for price purposes as ***** useable. Commencing March 1, 2006, the actual percentage of useable material shall be used for price purposes and any boules that are nonconforming product will not be priced. Boules that are not ***** useable but that are not made available for return to Jesperator as nonconforming product will be evaluated for price using the formula above.

Nonconforming product: Material shipped to C&C, where the defect-free material fraction is less than ***** of a boule.

March 7, 2007

Exhibit B

PRICING AND MINIMUM PURCHASE QUANTITIES

General Provisions:

Prior to March 1, 2006, any boule containing less than 100% but at least ***** useable material shall be treated as 100% useable material for quantity purchase and pricing purposes. Commencing March 1, 2006, the price of any boule containing less than 100% useable material, as set forth in Exhibit A shall be adjusted as set forth in Exhibit A.

Phase 1: C&C will pay ***** within 10 days of signing this Agreement as a first payment for a five month ***** Research and Development (R&D) effort by Jesperator that starts March 1, 2005. This effort is to improve color, tone and defect rate of the material. The color of the recently supplied material was acceptable, while the tone was at the lower end of acceptability. The defect rate was *****. This minimum quality is described in detail under Exhibit A “Specifications”. During this period Jesperator will supply C&C with five samples 2 to 2 ¹/4 inches in diameter and 5.2mm thick (Phase 1). The second and final ***** R&D payment will be made by C&C within 10 days of receipt of the fifth material sample.

Upon mutual agreement that the sample material generated during the R&D period is of acceptable quality the companies will designate from the sample material a color/tone master boule for which the useable material of that boule will be the minimum acceptable color/tone of future purchases. Defects will be evaluated on each individual piece of material.

Phase 2: Starting August 1, 2005 C&C will purchase minimum ***** grams and minimum subject to capacity ***** grams of material per week from Jesperator at ***** per gram with graded boules containing a minimum of ***** of useable material per the specifications in Exhibit A. If the useable portion of the boule is less than ***** of the total weight of the boule and C&C does not reject the boule as nonconforming product set forth in Exhibit A, then C&C will only pay for the grams of useable material contained within the boule.

Phase 3: Starting December 1, 2005, C&C will purchase a minimum ***** grams and minimum subject to capacity ***** grams per week from Jesperator at ***** per gram with each boule containing a minimum of ***** of useable material. If the useable portion of the boule is less than ***** of the total weight of the boule and C&C does not reject the boule nonconforming product set forth in Exhibit A, then C&C will only pay for the grams of useable material contained within the boule.

Phase 4: Starting April 1, 2006 C&C’s purchases will increase to a minimum ***** grams and minimum subject to capacity ***** grams per week at ***** per gram of useable material.

Phase 5: Starting July 1, 2006 C&C’s purchases will increase to a minimum ***** grams and minimum subject to capacity ***** grams of per week at ***** per gram of useable material.

Phase 6: Starting July 1, 2007, subject to Jesperator having made an industrialization decision and having moved its SiC activities from the current locations to a planned industrial facility C&C will purchase a minimum ***** grams and minimum subject to capacity of ***** grams per week at a price of ***** per gram of useable material. Should this condition not become valid, delivery conditions as defined in Phase 5 above shall remain in force, until the said condition will be met. In such case, however, the price of the products will be set at ***** per gram.

Additional Term: Should there be an Additional Term, C&C will purchase a minimum ***** grams and a minimum subject to capacity (subject to possible increase to ***** of C&C’s SiC requirements in any quarter pursuant to Section 2.1 of this Agreement) of ***** grams per week at ***** per gram of useable material.
