    3M to Acquire Electronic Interconnect Manufacturer Robinson Nugent, Inc.

AUSTIN, TEXAS & NEW ALBANY, IND. - October 3, 2000 - 3M (NYSE: MMM) and Robinson
Nugent,  Inc.  (NASDAQ:  RNIC)  announced  today that they have  entered  into a
definitive merger agreement under which 3M will acquire Robinson Nugent, Inc., a
New Albany,  Indiana-based  manufacturer of electronic interconnect products for
approximately  $115  million,  including the  assumption of debt.  The merger is
structured as a tax-free, stock-for-stock transaction, in which each outstanding
Robinson  Nugent,  Inc.  common share will be exchanged  for $19.00 of 3M common
stock, subject to certain collar provisions.

The  transaction  has been approved by the boards of directors of both companies
and is subject  to  approval  by the  shareholders  of  Robinson  Nugent,  Inc.,
customary  closing  conditions,  and  regulatory  reviews.  The  transaction  is
expected to close in late 2000 or in early 2001.  Upon completion of the merger,
Robinson Nugent, Inc., will become a wholly owned subsidiary of 3M.

3M also  entered  into a voting and stock option  agreement  with four  Robinson
Nugent, Inc. stockholders,  owning approximately 31% of the outstanding Robinson
Nugent,   Inc.  common  shares  on  a  fully  diluted  basis,  under  which  the
shareholders  have agreed to vote their shares in favor of the merger and 3M has
the option in certain  circumstances  to acquire  the shares for cash at $19 per
share.



John K. Woodworth,  general manager, 3M Interconnect  Solutions Division,  said,
"Robinson Nugent is an innovative company with talented people and fast growing,
quality products. This acquisition broadens our product base by giving us higher
speed copper  interconnects,  complements our customer  relationships,  and fits
into our strategy to expand further in the telecommunications  sector.  Further,
we believe we will  realize  additional  synergies  between our  technology  and
product  platforms,   as  well  as  our  customer  bases  and  cultures.   We're
enthusiastic  about the  prospects of joining  forces with  Robinson  Nugent and
successfully growing this business."

"We're delighted to be linking up with 3M, "said Patrick Duffy,  chairman of the
board, Robinson Nugent, Inc.. "We believe this transaction will create value for
shareholders  and customers of both  companies.  Our products and  technological
expertise,  and our track record at innovation,  when combined with those of 3M,
will open a whole new realm of  possibilities.  I wish to assure  our  customers
that there will be no disruption in service during this  transition and that the
combined resources of 3M and Robinson Nugent should strengthen  opportunities to
work together in the future."
