Letterhead CRAIG Griff Resor MRS Technology, Inc. 10 Elizabeth Drive Chelmsford, MA 01824 Dear Griff, As I mentioned to Jack Steele, I have become an Equity Partner at Andersen Consulting. Unfortunately, partnership rules preclude a partner from being a Director of a "for Profit" entity, apart from a closely held family enterprise. Consequently, I hereby resign as chairman of the Compensation Committee and a Director of MRS. As Jack knows, I will be in Asia through 1 October, but I will be in touch upon my return. Most Sincerely, /s/ S. Russel Craig
