Incorporated (NASDAQ Global Select: IIVI) announced today that its Board of Directors has authorized the Company to purchase up to 500,000 shares of its Common Stock, representing approximately 1.7% of the Company&#146;s total outstanding shares.
The purchases, which will be made in the open market or in privately negotiated transactions as permitted by Securities Exchange Act Rule 10b-18, could begin immediately and may occur from time to time in the future, and the Company may suspend or
discontinue this purchase program at any time. Shares purchased by the Company will be retained as treasury stock and will be available for general corporate purposes. The Company expects the repurchase of shares to at least partially offset the
dilutive effect of the issuance of shares from the Company&#146;s stock option plan. The Company will finance the repurchases from cash-on-hand and amounts available under the Company&#146;s existing credit facility. </FONT></P> <P
