Allstar Systems Announces Sale Of It's Telecom Systems Division

HOUSTON,  March 17, 2000  /PRNewswire/ -- Allstar Systems,  Inc.  (Nasdaq:ALLS),
today announced that it has consummated a transaction with Communications  World
International,  Inc. ("CommWorld") (OTC Bulletin Board: CWII) in which CommWorld
has purchased certain assets and the ongoing business  operations of its Telecom
Systems division.

In the transaction,  Allstar Systems will sell its inventory and work-in-process
projects  to  CommWorld.  CommWorld  will  offer  employment  to all of  Allstar
Systems'  Telecom Systems  division  employees and will support the customers to
whom Allstar Systems has provided  telephone systems and/or support in the past.
Price and Terms were not disclosed. Related to this transaction, Allstar Systems
that it expects to  recognize a loss on disposal of  approximately  $1.1 million
net of tax in its fourth quarter  ending  December 31, 1999. For the nine months
ended  September 30, 1999,  the Telecom  Systems  division  produced a loss from
operations of $979,000 before interest and taxes.

James H. Long,  President and Chief Executive Officer of Allstar Systems stated,
"From a  financial  results  perspective,  we have  not been  successful  in our
attempts to operate this business  unit.  Our board of directors  decided in the
fourth quarter of 1999 to seek a divestiture of the Telecom  Division  through a
sale of the  division to a third party or  otherwise.  We sought out and found a
solution  that we  believe is the best  possible  alternative.  We believe  that
CommWorld,  which  has a  long  track  record  of  success  and  growth  in  the
telecommunications  systems  industry,  will  take  excellent  care of the loyal
customers and employees of our Telecom Systems division."

Jim  Ciccarelli,  CEO of CommWorld,  stated,  "We are excited about our entrance
into the Houston  market and this  transaction  with  Allstar  Systems.  We look
forward  to the  opportunity  to build  upon the  base of loyal  customers  that
Allstar Systems has built. With CommWorld's industry and operational  expertise,
we believe that we will be able to quickly build a dominant  organization in the
Houston market. Allstar Systems' Telecom Systems division presence in the Dallas
market  will  complement  our  already  strong  presence  in that  market.  This
transaction will continue our rapid expansion in the Texas market and complement
our existing operations in the Dallas/Ft. Worth metroplex area.
