II-VI Incorporated Makes Offer to Laser Power Corporation's
Board;

Offers .052 Shares of II-VI Stock Plus $2.32 Cash for each Share
of Laser Power Stock;

Transaction Valued at $4.25 per Share, with Minimum Price of
$4.05 per Share


Pittsburgh--June 5, 2000--II-VI Incorporated (NASDAQ NMS:  IIVI)
announced today that it has made an offer 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 2, 2000, the value of this offer to Laser Power's
stockholders is $4.25 per share.  This represents a premium over
the offer made by Union Miniere.

Laser Power's stockholders will be guaranteed a "floor" of $4.05
per share.  II-VI will 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.

Fran Kramer, President and Chief Operating Officer of II-VI, said
"Our offer represents substantially greater value for Laser
Power's stockholders than Union Miniere's current proposal with
appropriate downside protection.  Our transaction is in the best
interests of both Laser Power's and II-VI's stockholders.  We
think the potential synergies of the transaction are significant.
We believe that the transaction will result in increased
operating efficiencies and productivity.  There also will be
significant cost savings resulting from the supply of raw
materials internally produced by II-VI which Laser Power
currently purchases from third parties.  With these cost savings
and the resulting improved margins, and by leveraging our sales
efforts, we believe that the transaction will be accretive in our
fiscal year beginning July 1, 2000.  Our proposal would allow
Laser Power's stockholders to participate in this upside
potential."

The offer contemplates that the transaction will be structured as
an exchange offer for Laser Power shares.  Following the exchange
offer, II-VI and Laser Power would consummate a merger in which
each share of Laser Power common stock not tendered into the
exchange offer would be exchanged for the same consideration paid
in the exchange offer.

                                     structured as an exchange

* Other Terms                        We are prepared to enter into
                                     an agreement providing for
                                     the transaction on the same
                                     terms as set forth in your
                                     agreement with Union Miniere
                                     USA Inc., with appropriate
                                     changes to reflect the terms
                                     of our offer and to reflect
                                     the conditions below.

Based on the closing market price of II-VI stock on June 2, 2000,
our offer has an implied value of $4.25 per share of Laser Power
stock.  This makes our offer clearly superior to the terms of the
Union Miniere transaction.  Not only does our offer have a higher
indicated value than the Union Miniere transaction, it gives Laser
Power stockholders the opportunity to participate in the upside
opportunity created by the combination of II-VI and Laser Power.
This makes our offer compelling from the point of view of Laser
Power's stockholders.

As you well know, II-VI has been enthusiastic about acquiring
Laser Power for several years now.  II-VI is a growing company and
we think that Laser Power can be an important component of our
future.  Our plans are to combine our businesses in a way that
maintains the Laser Power brand name and its role in the market
place.  We intend to maintain and even grow Laser Power's Temecula,
Mexican and Belgium manufacturing facilities.  These facilities
fit well into our worldwide manufacturing strategy.  We intend to
make your San Diego office our West Coast sales and marketing
headquarters and your office in Belgium will nicely complement
our global sales and marketing efforts.  For these reasons, it
is important to us to retain all of Laser Power's key employees
and we intend to offer them an extremely competitive compensation
package, including II-VI stock options, to accomplish that.

Your Board's fiduciary duties under Delaware law require you to
consider this offer.  We believe that if you evaluate this offer
in accordance with those duties you will conclude that it is
superior to the terms of your agreement with Union Miniere.

Our proposed transaction will be conditioned upon, among other
things, (i) the tender into our exchange offer of not less than a
majority of the shares of Laser Power corporation common stock
outstanding (including the shares of Laser Power stock owned by
II-VI), (ii) the valid termination of the merger agreement
between Laser Power and Union Miniere, with the payment by Laser
Power to Union Miniere of any fees or expenses in connection with
such termination not to exceed $2 million, (iii) the approval of
II-VI's exchange offer and its proposed merger by Laser Power's
Board of Directors, (iv) receipt of all required regulatory
approvals, (v) the redemption of the outstanding preferred stock
purchase rights under Laser Power's preferred stock purchase
rights plan or the amendment of the plan to make it inapplicable
to II-VI's offer, and (vi) Laser Power not taking any action that
would impair II-VI's ability to acquire Laser Power or otherwise
diminish the value of Laser Power to II-VI.

This offer has been approved by II-VI's Board of Directors.  As
you can appreciate, time is of the essence.  Accordingly, if you
do not respond favorably to our proposal by Noon, Eastern Time,
on June 11, 2000, it will automatically terminate and we will be
forced to consider our other alternatives.

I look forward to hearing from you shortly and to working with
you so that we may bring our clearly premium proposal to a vote
of your stockholders.

                                                Sincerely,
                                                /s/ Carl J. Johnson

                            ****
