II-VI Incorporated Extends Deadline for Offer to Laser Power
Corporation's Board; Offer of .052 Shares of II-VI Stock Plus $2.32 Cash
for each Share of Laser Power Stock with Minimum Price of $4.05 per Share
to Expire at 11:59 p.m. EDT on Wednesday, June 14, 2000

Pittsburgh--June 12, 2000--II-VI Incorporated (NASDAQ NMS:  IIVI)
announced today that it has extended, until 11:59 p.m. on Wednesday,
June 14, 2000, the expiration of its offer made to the Board of Directors
of Laser Power Corporation (NASDAQ NMS: LPWR) to acquire, in a consensual
transaction, all of Laser Power's outstanding stock.  Under II-VI's
proposal, each share of Laser Power stock will receive .052 shares of
II-VI common stock and $2.32 in cash.  Based on the closing market price
of II-VI common stock on June 9, 2000, the value of this offer to Laser
Power's stockholders is $4.45 per share.  This represents a greater than
10% premium over the offer made by Union Miniere.

Under II-VI's proposal, Laser Power's stockholders would be guaranteed a
"floor" of $4.05 per share.  II-VI would pay this guaranteed price with a
combination of cash and/or II-VI stock, at its election, if the volume
weighted average trading price of II-VI common stock is less than $33.27
per share for the 20 trading days prior to the closing of the exchange
offer.  The offer also contains a ceiling of $5.00 per share.

II-VI also stated that it advised the Laser Power Board that its
agreement with Laser Power would contain a provision to reimburse Laser
Power $2.5 million in the event that a transaction with  II-VI is not
consummated under certain circumstances.

Fran Kramer, President and Chief Operating Officer of II-VI, said "This
is a strong offer.  It represents substantially greater value for Laser
Power's stockholders than Union Miniere's current proposal with more than
appropriate downside protection.  Our transaction clearly is in the best
interests of both Laser Power's and II-VI's stockholders."

If II-VI's offer is accepted by the Board of Directors of Laser Power, it
would prepare and file a registration statement with the Securities and
Exchange Commission.  Laser Power stockholders would then be able to
obtain such materials for free at the Commission's Web site at
www.sec.gov.  Laser Power stockholders are urged to carefully read the
complete terms and conditions of those materials prior to making any
decisions with respect to an actual offer.

This document contains forward-looking statements concerning the
financial condition, results of operations and business of II-VI and its
proposed acquisition of Laser Power, the anticipated financial and other
benefits of such proposed acquisition and the plans and objectives of
II-VI's  management following such proposed acquisition, including,

(A) the likelihood of consummating the proposed acquisition, (B) the cost
savings expected to result from the proposed acquisition, (C) anticipated
results of operations of the combined company following the proposed
