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

       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.
