AUSTIN, TEXAS & NEW ALBANY, IND. - October 3, 2000 - 3M (NYSE: MMM) and

into a definitive merger agreement under which 3M will acquire Robinson

interconnect products for approximately $115 million, including the
assumption of debt. The merger is structured as a tax-free, stock-for-stock

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.

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.

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."
