NEMATRON ANNOUNCES 5-FOR-1 REVERSE STOCK SPLIT, NAME CHANGE AND SALE OF ASSETS
AND LIABILITIES

ANN ARBOR MI -- MARCH 19, 2004 -- Nematron Corporation (OTCBB:NMNN) announces
that the Board of Directors of Nematron has approved a five-for-one reverse
stock split of its outstanding common shares, the sale of the Assets and
Liabilities of the Company to NC Acquisition Corporation, and the renaming of
the Company to Sandston Corporation. The Shareholders had authorized these
transactions at Nematron's recent Annual Shareholder Meeting held on January 13,
2004.

The reverse split will be effective at the opening of business on March 31,
2004. As a result of the split, Shareholders of record at the close of the
business day on March 30, 2004 will receive one common share for every five
shares currently held. Nematron's transfer agent, Registrar & Transfer, will
notify the Company's Shareholders and request that they surrender their
certificates representing shares of pre-split common stock to the transfer agent
so that certificates representing the appropriate number of shares of post-split
common stock, together with a cash payment in lieu of any fractional share, may
be issued in exchange. The price for fractional shares will be based on the
closing market price of Nematron's common stock on March 30, 2004. The company's
stock was trading at 11 cents a share at the close of Thursday's trading.

Effective at the end of the business day on March 31, 2004, the Company name
will be changed from Nematron Corporation to Sandston Corporation. Trading of
Sandston Corporation stock will continue under the current ticker (OTCBB:NMNN),
although it is anticipated that the ticker symbol will be changed in the near
future. Post-split common stock certificates will be issued from Sandston
Corporation.

The Board of Directors has also approved the sale of substantially all of the
Company's assets and liabilities to NC Acquisition Corporation, an Ann Arbor,
Michigan-based company. Following this sale, also effective at the end of the
business day on March 31, 2004, the operations of the current Company will
continue under the name of Nematron Corporation. Nematron will continue to
operate from its Ann Arbor-based headquarters, with no anticipated disruption in
the day-to-day business with our many customers and distributors worldwide.
