               SAVILLE ANNOUNCES PRELIMINARY FIRST QUARTER RESULTS


Burlington,  Mass.,  April 7, 1999 -- Saville Systems PLC (NASDAQ:  SAVLY) today
announced that,  based on a preliminary  review,  the Company's  results for the
first  quarter  ended March 31,  1999 will be below  Company  expectations.  The
Company expects to report revenue for the quarter of between approximately $30.0
million and $32.0 million and a loss per share of between approximately $.05 and
$.09. Saville expects to report actual results for the first quarter on or about
April 27, 1999.

The Company's new license sales were adversely  affected by a lengthening of the
sales cycle due, in part, to uncertainty  caused by recent  consolidation  among
the  Company's  competition,  as well as the  marketing  issues  related to UNIX
customers  going into  production  later in the quarter than expected.  Services
revenue was lower than  anticipated  due to the shortfall in new license  sales,
several existing  customers'  changing  implementation  schedules and additional
work  required  during the  quarter  to bring  several  initial  UNIX sites into
production.

John J. Boyle III,  Saville's  Chairman and CEO,  commented,  "We are  obviously
disappointed  that we closed  significantly  less business than anticipated this
quarter.  Although our visibility  remains  limited by continuing  uncertainties
associated  with current  market  conditions,  we do expect revenue and earnings
growth for the year.  We were also  disappointed  to receive a letter  late this
quarter from Cellular South, a customer of our initial UNIX release,  purporting
to  terminate  our  agreements.  We are  confident  that  the  system  developed
specifically for Cellular South meets our commitment  under our agreements,  and
we believe that there is no basis for their actions. Importantly, we are pleased
that we were able to bring several of our UNIX customer sites into production in
the past  month,  which we expect to assist us in our  marketing  efforts  going
forward."

statement  relating to revenue and  earnings  growth,  that  involve a number of
risks and  uncertainties.  Important  factors that could cause actual results to

set forth under the heading  "Certain Factors That May Affect future Results" in
Appendix  B of the  company's  Annual  Report  on From  10-K for the year  ended
December 31, 1998,  including  risks  associated  with  customer  concentration,
intense competition, product development and acceptance, the management of rapid
operations expansion and the availability of favorable tax treatment.
