PLASMA-THERM*, INC. ANNOUNCES FIRST QUARTER 1999 RESULTS

March 15, 1999, St. Petersburg, Florida, Plasma-Therm, Inc. (NASDAQ NMS: "PTIS")
announced today its first quarter 1999 results. For the three months ended
February 28, 1999, the Company reported a net loss of $1,410,102, or $.13 per
diluted share, compared to net income of $1,473,680, or $.13 per diluted share,
for the same period last year. Included in the net loss for the three months
ended February 28, 1999 was an additional restructuring charge of $805,036
(pre-tax) related to services provided by TRW/BDM International pertaining to
the Company's implementation of the Supply Chain Management (SCM) program.
Excluding this restructuring charge, the Company's net loss for the three months
ended February 28, 1999 would have been $884,102, or $.08 per diluted share.
Plasma-Therm also reported net sales for the quarter of $9,296,375, compared to
$12,311,720 for the same period in 1998. Backlog for the first quarter of 1999
was approximately $5,000,000, compared to $16,000,000 for the first quarter of
1998.

Management believes the results for the period ended February 28, 1999 are due
to the continued slowdown in the Company's four market segments, specifically
data storage's slower than anticipated recovery (historically, a substantial
marketplace for Plasma-Therm). These markets have experienced a late slowdown,
as compared to the semiconductor marketplace, which appears to be consistent
with its late recovery.

As a result of the continued slowdown in the marketplace, management has made
the decision to implement further reductions. With restructuring of overheads
and reduction in personnel, the Company's overall overhead should be reduced by
approximately 15 - 20%. The effect will not be fully realized until the third
quarter of 1999.

Through its reorganization efforts, the Company has put into place individual
business units for its four key markets, optoelectronics/telecommunications,
data storage, microelectromechanical and photomask. Management believes this
effort will allow Plasma-Therm to make a greater penetration into these existing
marketplaces, with the potential for increased market share into the year 2000
and beyond. This business structure is one of the results of the SCM program. In
addition, throughout the reorganization, the Company is continuing to implement
the SCM process developed with TRW/BDM International. The majority of the costs
associated with the program have already been realized.

The impact of the restructuring and reorganization efforts should allow the
Company to reduce losses in its second quarter and return to approximately break
even for the remainder of 1999. At the present time, looking forward, management
does not have visibility into the year 2000. However, with the new
organizational structure in place, resulting in reduced operating costs and the
anticipated demand for the Company's products, a return to profitability is
expected.

In addition, management has made the decision to take a more conservative
approach with its Physical Vapor Deposition (PVD) system development program, to
ensure that the beta systems have the greatest degree of success in the
production tool marketplace. This will result in a revised shipment date of late
1999, previously targeted for February, 1999. Although the Company is in the
midst of a restructuring, the decision has been made to continue the support of
this unique process and product development program. Dependent on the
marketplace and general product demand in the year 2000, this product line could
add considerable revenue for the Company in the data storage market.

To preserve cash-flow, the construction of the R&D, Customer Applications and
Training Center is being delayed for approximately six months. At the end of
this period, management will re-evaluate the construction project based on the
current market conditions.

Effective March 15, 1999, Scott Deferrari, President and CEO, will be on a
30-day medical leave of absence. During that time, Ronald H. Deferrari, the
Company's founder, Chairman of the Board and former CEO, will resume the duties
of CEO.

Even though the Company is going through a reorganization, we feel that the
strength of our current market position, product lines and technology, and new
organizational structure positions the Company for a bright future.
