Intent with Steiner Atlantic Corp.
- ----------------------------------

Milpitas, CA May 15, 1998 - Metro Tel Corp. (Nasdaq: MTRO), announced today that
it has entered  into a  Memorandum  of Intent with  Steiner  Atlantic  Corp.,  a
privately  held  corporation  located in Miami,  Fl,  calling  for the merger of
Steiner  Atlantic Corp. with Metro Tel Corp. The merger  contemplates a "pooling
of interest"  transaction  under which Metro Tel Corp.  will issue shares of its
common  stock to the  shareholders  of Steiner  Atlantic  Corp.,  as a result of
which,  Steiner Atlantic Corp.  stockholders  will own  approximately 70% of the
combined company.  At the conclusion of the transaction,  it is anticipated that
Metro Tel Corp. will change its name to Aero-Tech Corporation.

Steiner  Atlantic  Corp.,  which is a distributor of industrial  laundry and dry
cleaning  equipment and allied products  serving the southeast United States and
Latin  American  markets,  is  operating  profitably  and had 1997  revenues  of
approximately $14 million.

On a  pro-forma  basis  the  combined  company  would  have  shown  revenues  of
approximately  $18 million  for the year ended  December  31, 1997 and  adjusted
earnings of approximately $800,000.

Michael Steiner,  president of Steiner Atlantic Corp.,  will become president of
the combined company and Venerando J. Indelicato,  president of Metro Tel Corp.,
will become Chief  Financial  Officer.  Both  executives  view the merger as the
basis for building a much larger enterprise.

The investment  banking firm of Slusser  Associates acted as an advisor to Metro
Tel Corp.

The  transaction  is subject to, among other things,  entering into a definitive
agreement,  approval  of  both  boards  of  directors  and the  approval  of the
shareholders of both companies.

The merger is expected to be completed by October 31, 1998.
