          II-VI MAILS REVISED EXCHANGE OFFER MATERIALS;
          EXTENDS LASER POWER OFFER TO AUGUST 11, 2000


PITTSBURGH, PA - Aug. 7, 2000 / PRNewswire/ - II-VI Incorporated
(Nasdaq:  IIVI) is mailing revised exchange offer materials today to
stockholders of Laser Power Corporation (Nasdaq:  LPWR).  II-VI is
offering to exchange .052 share of II-VI common stock and $2.89 in cash
for each outstanding share of Laser Power common stock (including the
associated rights to purchase preferred stock).

The merger agreement between II-VI and Laser Power provides that Laser
Power stockholders will receive a guaranteed "floor price" of $5.15 per
share payable in II-VI common stock and cash.  Under the merger
agreement, the guaranteed aggregate "floor price" of $5.15 per share
will be calculated by reference to the twelve trading days ending three
trading days prior to the expiration date of the offer.  If the
weighted average market price of II-VI common stock for the twelve days

less than $43.46, then II-VI will pay .052 share of II-VI common stock
plus an additional amount of cash so that the aggregate amount of the
consideration is $5.15 per share.
