        HADCO CORPORATION ADOPTS STOCKHOLDER RIGHTS PLAN


August 22, 1995 -- Hadco Corporation announced today that its
Board of Directors has adopted a Stockholder Rights Plan in which
Common Stock Purchase Rights will be distributed as a Rights
dividend at the rate of one Right for each share of Common Stock
held as of the close of business on September 11, 1995.

The Rights Plan is designed to deter coercive or unfair takeover
tactics and to prevent an acquiror from gaining control of the
Company without offering a fair price to all of the Company's
stockholders.  The Rights will expire on September 11, 2005.
Patrick Sweeney, the Company's President and Chief Executive
Officer, said that the Stockholder Rights Plan was not adopted by
the Board in response to any specific offer or threat, but rather
is intended to protect the interests of stockholders in the event
the Company is confronted in the future with coercive or unfair
takeover tactics.  He also indicated that similar plans have been
adopted by over 1500 public companies.

Each Right will entitle holders of Company Common Stock to buy
one share of Common Stock of the Company at an exercise price of
$130.  The Rights will be exercisable only if a person or group
acquires more than 20% (exempting the stock ownership of
Horace H. Irvine II, the founder and Chairman of the Board of the
Company, and certain related persons and entities) of the Common
Stock, or announces a tender or exchange offer which would result
in its ownership of 25% or more of the Common Stock, or a person
owning 10% or more of the Common Stock is determined by the Board
to be an Adverse Person, as defined in the Rights Plan.

If any person or group becomes the beneficial owner of 25% or
more of the Common Stock except pursuant to a tender offer for
all shares at a price that a majority of the independent
directors determines to be fair; a more-than-20% stockholder
engages in a merger with the Company in which the Company
survives and its Common Stock remains outstanding and unchanged;
certain other self-dealing events involving the Company and a
more-than-20% stockholder occur; or, under certain circumstances,
the Board determines a 10% or more stockholder to be an Adverse
Person, each Right not owned by such person or related parties
will entitle its holder to purchase, at the then current exercise
price of the Right, Common Stock 

of the Company (or, in certain circumstances as determined by the 
Board, a combination of cash, property, Common Stock or other 
securities or a reduction in the exercise price) having a value of 
twice the Right's exercise price.  In such circumstances, the Company 
may also exchange one share of Common Stock for each Right outstanding.  
In addition, if the Company is involved in a merger or other business
combination transaction with another person in which its Common
Stock is changed or converted, or sells or transfers more than
50% of its assets or earning power to another person, each Right
that has not previously been exercised will entitle its holder to
purchase, at the then current exercise price of the Right, shares
of Common Stock of such other person having a value of twice the
Right's exercise price.

The Company can in certain circumstances redeem the Rights at
$0.01 per Right.  The Rights will expire on September 11, 2005
unless earlier redeemed or exchanged.

Details of the Stockholder Rights Plan are outlined in a letter
which will be mailed to all stockholders.
