ATTACHMENT A

Specification of usable material as referenced in paragraph 2 above.

COLOR: Usable material is calculated as “light xxxx” or “very light xxxx”. Specifically tone/color number 20 and 10 ¹ as used in the Xxxxxxx & Xxxxxxx xxxxx-grading screen will be considered acceptable tone and color material. (Note: Grade 10 is preferred. Grade 20 material will be valued at *****.

DEFECTS:

Material volume of acceptable color will be reduced by the percentage of the defects listed in the table below. Xxxxxxx & Xxxxxxx shall set the acceptable standards for the quality of both the color and defects of all material purchased pursuant to this letter agreement. Unless otherwise mutually agreed by the parties in writing, however, the grading of the material by both Cree and Xxxxxxx & Xxxxxxx will adhere to those standards and methods identified in Notes 1-3 below, applied on a consistent basis in the same manner as applied during September, October and November of calendar 2003. Should Xxxxxxx & Xxxxxxx xxxx such standards and methods or new defects unacceptable, it can request changes to its volume commitment or the methods, standards or list of price reducing defects, with such changes to be effective 60 days after giving Cree notice of the changes. Cree may request changes to its pricing and/or volume commitment. If the parties do not agree in writing on the changes to be made, before the effective date of the requested changes, either party can terminate this agreement upon notice and, in that event, the Supply Agreement will govern the parties’ obligations thereafter.

Notes

1 CH0257R 17.4mm tone/color 20 (lightest 20), new gray boules that are lighter than this will grade as 10, CE0269R 9.5mm tone/color 30 (lightest 30), new gray boules that are lighter than this will grade as 20

2 Micropipe grading will be performed according to the Cree document identified as the CCG – 948 Dense Fine Pipe Grading procedure (Revision 12/3/03). The area determined according to this procedure multiplied by 1.2, (“20% adder”), defines the area of non-usable material for micropipes.

3 Crystals CC0213R, CH0165R and CH0215R represent ***** grading.
