Acquisition from Dover Corp.

SENIOR PLC
2 August 1999


              Senior Acquires World Leading US Flexonics Business
                                       
                                       
SENIOR PLC is pleased to announce that it has acquired the entire issued share
capital of Pathway Bellows, Inc. ('Pathway') from Dover Corporation ('Dover'),
for a total cash consideration of approximately  £22.3 million (US$35 million)
on  a  debt  free basis.  Pathway, based in Tennessee, is the world's  largest
manufacturer of expansion joints.

In  the  year  ended 31 December 1998, Pathway's unaudited sales  and  profits
before  taxation  and  exceptional  items  were  approximately  £26.6  million
(US$41.8 million) and £2.2 million (US$3.5 million) respectively.

The  consideration is being financed from the Group's existing facilities.   A
further payment of not more than £0.9 million (US$1.4 million) will be made on
1  November  1999 to Dover, in return for which Senior is expected to  receive
future  tax  benefits, the projected net present value of which  substantially
exceeds  the  additional  payment.  The anticipated value  of  net  assets  at
closing is approximately £4.5 million (US$7.0 million).

Pathway  is  the  recognised  world  leader  in  expansion  joint  technology.
Flexible  metallic expansion joints of up to 10 metres diameter  are  used  in
petrochemical  and  power generation plants in high temperature  and  pressure
applications.  Over  the  next 12 months, Pathway  and  Senior's  existing  US
expansion  joint  operation  in Texas will be  merged.   One-off  capital  and
revenue  costs  totalling  approximately £4.8  million  (US$7.6  million)  are
anticipated  to  generate  annual savings of at  least  £1.9  million  (US$3.0
million).   Senior has additional expansion joint manufacturing operations  in
the UK, Denmark and Brazil and further sales operations in Asia, where Pathway
is particularly well-represented.

Commenting on the acquisition, Andrew Parrish, Senior's Group Chief  Executive
said;  'The  acquisition of the world's largest expansion  joint  manufacturer
presents an exciting opportunity for Senior to become the clear market  leader
in  this  $300  million global market, the size of which is expected  to  grow
significantly  over  the next three years, particularly in  the  petrochemical
sector.    Pathway  is  a  substantial  addition  to  Flexonics'   Specialised
Industrial   Division,  representing  a  further  significant   step   towards
reinforcing and building upon Senior's established position as world leader in
the  manufacture  and  marketing of thin walled flexible metallic  tubing  and
bellows.  The acquisition marks the first stage of Senior's programme  rapidly
to  reinvest,  in  our  core Flexonics business, the proceeds  of  the  recent
disposal of the bulk of our Engineered Products & Services activity.'

SENIOR PLC simultaneously announces that on 2 July 1999 it acquired the entire
issued  share capital of Hydro-Flex Inc. ('Hydro-Flex'), Canada,  for  a  cash
consideration of approximately £2.0 million (C$4.7 million), together with the
assumption of debt of approximately  £0.2 million (C$0.5 million). The company
manufactures  and  distributes flexible metal hose, PTFE  (Teflon)  hose,  and
manifold  assemblies for the specialised industrial market, in particular  for
steel plant and cryogenic applications.

In  the  year  ended 28 February 1999, the unaudited sales of Hydro-Flex  were
approximately  £1.9  million (C$4.5 million).  The  consideration,  which  was
financed from the Group's existing borrowing facilities, is dependent  on  the
net asset value at closing, which at the time of closing was anticipated to be
approximately £0.9 million (C$2.0 million), excluding debt assumed.

Hydro-Flex, founded in 1965, is located in Ontario and has 18 employees.   The
acquisition,  which will be fully integrated with Senior's  existing  Canadian
operation  (also  in  Toronto),  will  extend  Senior's  customer   base   and
distribution channels and will reinforce Senior Flexonics' leadership in  this
small but valuable market.
