            ------------------------------------------

       On February 24, 2005, the Board of Directors of II-VI Incorporated
(the "Company"), upon recommendation by the Compensation Committee,
approved an increase to the annual retainers and per diem Board Committee
stipends payable to the Company's non-employee directors.  Under the new
arrangement, which is effective as of January 1, 2005, non-employee
directors receive $15,000 annually in cash compensation for their service
on the Board. In addition, non-employee directors will receive $850 per
day for Board Committee meetings they attend.  A written description of
the arrangement is filed as Exhibit 10.1 hereto and is incorporated
herein by reference.

       The increase in director compensation described above and in
Exhibit 10.1 was part of an overall direct compensation plan approved by
the Board of Directors which also included a one-time grant to each non-
employee director of an option to purchase 5,400 shares of Company common
stock at an exercise price of $38.19 per share which was the fair market
value of the Company's common stock at the date of grant, February 24,
2005.
