MPW Industrial Services Group, Inc. (ticker: MPWG, exchange: NASDAQ) News
Release - 22-Aug-2000
-------------------------------------------------------------
MPW Special Committee and Management Revise Agreement in Principle to Acquire
The Company

HEBRON, Ohio, Aug. 22 /PRNewswire/ -- MPW Industrial Services Group, Inc.
(Nasdaq: MPWG) today announced that Chairman and Chief Executive Officer Monte
R. Black has withdrawn his previously announced proposal to acquire the Company
in a cash merger at $9.00 per share, which had been agreed to in principle by
the Special Committee of its Board of Directors and that, after further
negotiations, the Special Committee and Mr. Black have agreed in principle to a
revised proposal at $8.25 plus an additional amount if the sale of certain
Company assets generates proceeds in excess of targeted amounts. Mr. Black
withdrew the prior proposal after being unable to obtain a commitment to finance
the acquisition and assumption of MPW debt on terms acceptable to him.

The revised proposal is conditioned, among other things, on the sale of the
Company's Facilities Services Group (the "Division"). The Division is one of the
leading providers of filtration management and cleaning and maintenance
solutions to automotive assembly and component plants in North America. Under
the revised proposal, a corporation to be formed by Mr. Black would acquire the
Company in a cash merger at $8.25 per share, plus an adjustment amount from the
proceeds, if any, from the sale of the Division above certain levels. The
unaffiliated shareholders would receive 100% of any net after tax proceeds above
a threshold amount until they have received total consideration of $9.00 per
share, and thereafter 20% of any remaining net after tax proceeds. The merger
would not be completed unless and until the Division is sold, and any sale is
not expected to occur until early 2001.

The transaction is subject to final negotiation and execution of a definitive
merger agreement, including receipt by the Special Committee of a written
fairness opinion from its financial adviser, Deutsche Banc Alex. Brown. The
transaction will be further subject to approval by the holders of a majority of
the unaffiliated shares of the Company at a special meeting of shareholders to
be called to vote on the transaction. Mr. Black expects to have in place a
commitment to finance the share acquisition and the assumption of the remaining
debt of MPW upon execution of the merger agreement, which will follow the sale
of the Division and use of the sale proceeds to pay down debt. MPW shares closed
at $8.00 in trading yesterday.

The Company also announced that in connection with the anticipated privatization
of the Company, Daniel P. Buettin, Vice President and Chief Financial Officer,
and Robert J. Gilker, Vice President, Law and Administration, and Secretary,
have resigned as officers of the Company. Ira O. Kane, President and Chief
Operating Officer, will assume the duties of Chief Financial Officer until a
successor can be found.
