1. Cree will supply SiC production crystals to Charles & Colvard, and Charles & Colvard will purchase SiC production crystals from Cree, according to the terms stated in this agreement.

2. Charles & Colvard will purchase “usable material” (determined in the manner described in Paragraph 3) at a price of $[***] and according to the following quantities and schedule for the period of six months beginning July 1, 2002. Prices for purchases after calendar 2002 will be mutually agreed in writing from time to time.

7/1/02 – 9/29/02	[***]
9/30/02 – 12/29/02	[***]

Provided that Cree uses its best commercially reasonable efforts to deliver the quantities of usable material required by this agreement, Cree will not be held in breach for delays in delivery.

3. The quantity of “usable material” of crystals delivered to Charles & Colvard pursuant to this agreement will be determined according to the following:

A. Material will be graded according to specifications in Attachment A.

B. Grams of usable material will be calculated on a crystal by crystal basis according to the following equation: (usable mm) as a percent of total length of the crystal in mm multiplied by the actual weight of the crystal in grams. “Usable mm” means millimeters of usable material as defined in Attachment A.

C. Crystals shipped to Charles & Colvard must contain at least [***] grams of usable material for the 2” crystals or [***] grams for 3” crystals. This usable area must be contiguous. Crystal diameter to be shipped will be 2” or 3” as determined by Cree.

4. Charles & Colvard agrees to purchase a minimum of [***] of “usable material” (calculated in the manner described in Paragraph 3) each quarter during calendar 2003. For each quarter in calendar 2003 and thereafter, Charles & Colvard will provide Cree its minimum volume requirements in the form of firm purchase orders at least 30 days in advance of the quarter.

has not utilized on a daily basis as described below, for production for Charles & Colvard or for other Cree production, at least [***] crystal growers designated by Cree for the production of materials for Charles & Colvard, then Charles & Colvard agrees to pay Cree an unused capacity charge for the under utilized portion such crystal growers, up to a maximum charge of $111,222 per quarter. The charge per grower will be calculated as the product of $[***] per day times the number of days during the quarter on which no production runs were started in the grower for production for Charles & Colvard or for other Cree production. Cree will invoice the unused capacity charge on a quarterly basis on or after the last business day of each quarter; payment is due 30 days after the invoice date. As used in this agreement, “quarter” refers to fiscal quarters of Cree ending during the indicated period.

ATTACHMENT A

Specification of usable material as referenced in paragraph 2 above.

COLOR: Usable material is calculated as “light gray” or “very light gray”. Specifically tone/color number 20 and 10 ¹ as used in the Charles & Colvard boule-grading screen will be considered acceptable tone and color material (note: grade 10 is preferred. Grade 20 material will be valued at $[***] per-gram).

DEFECTS:

Material volume of acceptable color will be reduced by the percentage of the defects listed in the table below. Charles & Colvard shall set the acceptable standards for the quality of both the color and defects of all material purchased pursuant to this letter agreement. For pricing purposes the grading of the material by both Cree and Charles & Colvard will adhere to those standards from which a baseline has been established during the grading of 206 crystals during the first quarter of 2002. Should Charles & Colvard deem current standards or new defects unacceptable, then it can request changes to the standards or to the list of price reducing defects. At such time Cree has the option to make changes to its materials pricing and/or volume commitments.
