ITEM 3. IDENTITY AND BACKGROUND
 
  (a) The name and address of the Company, which is the person filing this
Statement, is as set forth in Item 1 above.
 
  (b)(1) Arrangements between Management and the Company. Certain contracts,
agreements, arrangements and understandings between the Company and certain of
its directors and executive officers are described in Annex A hereto, and
incorporated herein by reference.
 
  (2) Merger Agreement. The Company, the Purchaser and Parent have entered
into an Agreement and Plan of Merger dated as of August 14, 1995 (the "Merger
Agreement"), a copy of which is filed with this Statement as Exhibit (c)(1)
and incorporated herein by reference. The following is a summary of certain
provisions of the Merger Agreement. Such summary is qualified in its entirety
by reference to the Merger Agreement.
 
  The Offer. The Merger Agreement provides for the making of the Offer by the
Purchaser as described in Item 2 above. The obligation of the Purchaser to
accept for payment, purchase and pay for Shares tendered pursuant to the Offer
is subject to, among other things, there being validly tendered and not
withdrawn prior to the expiration date of the Offer a number of Shares
representing in the aggregate at least fifty-one (51%) percent of the total
outstanding Shares on a fully diluted basis, and certain conditions set forth
in the Offer to Purchase. The Purchaser has agreed that, without the written
consent of the Company, no change in the Offer may be made which reduces the
number of Shares subject to the Offer, decreases the price per Share payable
in the Offer, or modifies or adds to conditions to the Offer. If such
conditions are not satisfied, Purchaser has various options including the
right to terminate the Offer and return all tendered Shares.
 
  The Merger. The Merger Agreement also provides that, at the effective time
of the Merger, the Purchaser will be merged with and into the Company, and
each then outstanding Share (other than Shares owned by the Company, any
subsidiary of the Company, Parent, the Purchaser or any other subsidiary of
Parent or that are subject to dissenters' rights) will be converted into the
right to receive $22.50 per Share in cash, without interest.
 
  Pursuant to the Merger Agreement, the Company has agreed that, among other
things, during the period from the date of the Merger Agreement until the
effective time of the Merger, except as expressly contemplated by the Merger
Agreement or to the extent that the Purchaser shall otherwise agree in
writing, it will and will cause each of its subsidiaries to: (i) conduct its
operations only in the ordinary and usual course of business consistent with
past practice; (ii) not amend its Articles of Incorporation or By-laws; (iii)
not issue, reissue, sell
 
                                       2

or pledge, or authorize or propose the issuance, reissuance, sale or pledge of
any of its capital stock of any class, or securities convertible or
exchangeable into capital stock of any class or any rights, warrants or
options to acquire any convertible or exchangeable securities or capital stock
(other than the issuance of Shares upon the exercise of warrants and employee
stock options outstanding on the date of the Merger Agreement); (iv) not
declare, set aside or pay any dividend or other distribution (whether in cash,
securities or property or any combination thereof) in respect of any class or
series of its capital stock or otherwise make any payments to its shareholders
in their capacity as such (except for dividends from wholly owned subsidiaries
of the Company to the Company or to other wholly owned subsidiaries of the
Company); (v) not adjust, split, combine, subdivide, reclassify or redeem,
purchase or otherwise acquire, or propose to redeem or purchase or otherwise
acquire, any shares of its capital stock; (vi) not incur or assume any long-
term debt or any short-term debt or assume, guarantee, endorse or otherwise
become liable or responsible (whether directly, contingently or otherwise) for
the obligation of any person, except in the ordinary course of business
consistent with past practice and in an aggregate amount not to exceed
$500,000; (vii) not make any loans, advances (excluding the sale of products
to customers in the ordinary course) or capital contributions to, or
investments in, any person except in the ordinary course of business
consistent with past practice and in an aggregate amount not to exceed
$500,000 for any single borrower; (viii) not settle or compromise any suit,
proceeding or claim or threatened suit, proceeding or claim; (ix) except for
increases in salary, wages and benefits of employees of the Company or its
subsidiaries (other than executive officers of the Company) in accordance with
past practice, not increase the compensation or fringe benefits payable or to
become payable to its directors, officers or employees or pay any benefit not
required by any existing plan or arrangement or grant any severance or
termination pay to (except pursuant to existing agreements or policies), or
enter into any employment or severance agreement with, any director, officer
or employee of the Company or any of its subsidiaries or establish, adopt,
enter into, terminate or amend any collective bargaining or employee benefit
plan, agreement, trust, fund, policy or arrangement for the benefit or welfare
of any directors, officers or current or former employees, except to the
extent such termination or amendment is required by applicable law; (x) not
acquire or agree to acquire by merging or consolidating with, or by purchasing
a substantial portion of the assets of, or by any other manner, any business
or any corporation, partnership, association or other business organization or
division thereof or otherwise acquire or agree to acquire any assets, other
than transactions that are in the ordinary course of business and not material
to the Company or any of its subsidiaries; (xi) not sell, lease, mortgage or
otherwise encumber or dispose of or agree to sell, lease, mortgage or
otherwise encumber or dispose of, any of its assets, other than transactions
that are in the ordinary course of business and not material to the Company or
any of its subsidiaries; (xii) not modify, amend or terminate any contract or
prepay any indebtedness of the Company or forgive any indebtedness owed to the
Company, other than in the ordinary course of business consistent with past
practice and which is not material to the business of the Company and its
subsidiaries; and (xiii) not take any action that would or might result in any
of the representations of the Company set forth in the Merger Agreement
becoming untrue.
 
  The Company also agreed not to solicit, initiate, or encourage the
submission of any takeover proposal (as defined below), enter into any
agreement with respect to any takeover proposal or participate in any
discussions or negotiations regarding, or furnish to any person any
information with respect to, or take any other action to facilitate any
inquiries or the making of any proposal that constitutes, or may reasonably be
expected to lead to, any takeover proposal; provided, however, that prior to
the acceptance for payment of Shares pursuant to the Offer, to the extent
required by the fiduciary obligations of the Board of Directors of the
Company, as determined in good faith by a majority of the disinterested
members thereof based on the written advice of outside counsel (a copy of
which written advice shall be promptly furnished to Parent), the Company may,
in response to unsolicited requests therefor, participate in discussions or
negotiations with, or furnish information pursuant to an appropriate
confidentiality agreement to, any person. "Takeover proposal" means any
proposal, other than a proposal by Parent or any of its affiliates, for a
merger, consolidation, share exchange, business combination or other similar
transaction involving the Company or any of its subsidiaries or any proposal
or offer (including, without limitation any proposal or offer to shareholders
of the Company), other than a proposal or offer by Parent or any of its
affiliates, to acquire in any manner, directly or indirectly, an equity
interest in the Company or any of its subsidiaries, any voting securities of
the Company or any of its subsidiaries or a substantial portion of the assets
of the Company or any of its subsidiaries. The Board of Directors of the
Company, to the extent required
 
                                       3
<PAGE>
 
by the fiduciary obligations thereof, as determined in good faith by a
majority of the disinterested members thereof based on the written advice of
outside counsel (a copy of which written advice shall be promptly furnished to
Parent), may approve or recommend (and, in connection therewith, withdraw or
modify its approval or recommendation of the Offer, the Merger Agreement or
the Merger) a superior proposal (as defined below). "Superior proposal" means
a bona fide proposal made by a third party to acquire the Company pursuant to
a tender or exchange offer, a merger, a statutory share exchange, a sale of
all or substantially all its assets or otherwise on terms which a majority of
the disinterested members of the Board of Directors of the Company determines
in its good faith reasonable judgment (based on the advice of independent
financial advisors) to be more favorable to the Company and its shareholders
than the Offer and Merger and for which financing, to the extent required, is
then fully committed or (based on the advice of independent financial
advisors) is likely to be obtained in a timely manner.
 
  The Merger Agreement further provides that the Company will use its best
efforts to cause the holders of all outstanding warrants and employee stock
options to purchase Shares to agree, in writing, that such warrants and
options shall be surrendered and cancelled on the date of closing of the Offer
in exchange for cash payments by the Company to the holders of such warrants
or options in an amount not in excess of the difference between the price paid
for each Share pursuant to the Merger and the per Share exercise price of such
warrants or options, multiplied by the number of Shares subject to such
warrants or options.
 
  Parent presently intends to provide, for a period of one year following the
effective time of the Merger, employees of the Company with employee benefits
that are in the aggregate not materially less favorable to such employees than
those presently provided under the Company's current benefit plans. Parent has
agreed to cause to be maintained for a period of not less than three years
from the effective time of the Merger the policies of the directors and
officers' liability and fiduciary insurance most recently maintained by the
Company; provided that there may be substituted therefor policies of at least
the same coverage containing terms and conditions no less advantageous to the
beneficiaries thereof so long as such substitution does not result in gaps or
lapses in coverage with respect to matters occurring prior to the effective
time to the extent available; and provided further that Parent has no
obligation to provide such policies to the extent that the cost of maintaining
such policies would be substantially higher than the current cost to the
Company. In addition, Parent has agreed, for six years after the Merger, to
cause the surviving corporation in the Merger to indemnify and hold harmless
all officers and directors of the Company to the same extent such persons are
currently indemnified by the Company pursuant to the Company's Articles of
Incorporation and By-laws for acts or omissions occurring at or prior to the
effective time of the Merger.
 
  The Merger is subject to approval by the holders of a majority of the
outstanding Shares. The Purchaser intends to vote or to give written consent
with respect to all Shares acquired by it in the Offer or otherwise in favor
of the Merger. Accordingly, if the Purchaser purchases a majority of the
outstanding Shares pursuant to the Offer, the Purchaser will be able to effect
the Merger without the affirmative vote of any other holder of Shares.
Furthermore, if the Purchaser acquires at least 90% of the outstanding Shares
pursuant to the Offer, the Purchaser would, under Minnesota law, be able to
effect the Merger without any prior notice to, or vote by, the Company's
shareholders.
 
  The Merger is also subject to the satisfaction of certain conditions,
including: (a) the acceptance for purchase and payment for Shares by the
Purchaser pursuant to the Offer; (b) the receipt of all authorizations,
consents, orders or approvals of, the filing of all declarations with, and the
expiration of all waiting periods imposed by, all courts, arbitral tribunals,
administrative agencies or commissions or other governmental or regulatory
authorities or agencies, domestic or foreign ("Governmental Entities"),
necessary for the consummation of the transactions contemplated by the Merger
Agreement; (c) the absence of any temporary restraining order, preliminary or
permanent injunction or other order of any court of competent jurisdiction or
other legal restraint or prohibition preventing the consummation of the
Merger; and (d) the absence of any pending or threatened action, suit or
proceeding (other than the DCIS Investigation) by any Governmental Entity
before any court or governmental or regulatory authority against the Company,
Parent or the Purchaser or any of their subsidiaries challenging the validity
or legality of the transactions contemplated by the Merger Agreement.
 
                                       4
<PAGE>
 
In addition, the obligations of Parent and the Purchaser to effect the Merger
are subject to certain additional conditions, including: (a) the performance
in all material respects by the Company of its agreement under the Merger
Agreement and the accuracy in all material respects of the representations and
warranties of the Company set forth in the Merger Agreement; (b) the receipt
of all required authorizations, consents or approvals, the failure to obtain
which would have a material adverse effect on Parent and its subsidiaries or
the Company; and (c) the absence of, after August 14, 1995, in the reasonable
judgment of Parent, any change or development or prospective change or
development in the DCIS Investigation or the circumstances surrounding the
DCIS Investigation that could reasonably be expected to have a material
adverse effect on the Company. The Merger Agreement states that, for greater
certainty, such a change or development is deemed to include, without
limitation, the following: (i) any proceeding commenced by any Governmental
Entity for the suspension or debarment of the Company or any of its
subsidiaries from doing business with the United States (or any agency or
instrumentality thereof); (ii) any withdrawal of any governmental approval of
the quality control or quality assurance systems of the Company or any of its
subsidiaries or any removal of the Company or any of its subsidiaries from any
governmental "qualified products list"; (iii) any notification of the Company
or any of its subsidiaries that any of them is a target or a subject of a
criminal investigation; (iv) any indictment of the Company or of any of its
subsidiaries or of any of their respective directors or officers; (v) the
discovery of substantial evidence that any member of the senior management of
the Company was involved personally in material misconduct or that there exist
defects in the products of the Company or of any of its subsidiaries, which
defects are in excess of historical levels and, in the aggregate (and after
consideration of remedies reasonably available to the United States in
connection therewith), are reasonably likely to have a material adverse effect
on the Company; or (vi) any civil action, suit or proceeding commenced by any
Governmental Entity seeking legal or equitable relief. The obligations of the
Company to effect the Merger are subject to the accuracy in all material
respects of the representations and warranties made by Parent and the
Purchaser in the Merger Agreement and the performance in all material respects
of the agreements made by Parent and the Purchaser in the Merger Agreement. As
used in the Merger Agreement, any reference to any event, change or effect
being "material" or having a "material adverse effect" on or with respect to
an entity means such event, change or effect which is or is reasonably likely
to be materially adverse to the business, properties, results of operations or
financial condition of such entity and its subsidiaries taken as a whole.
 
  The Merger Agreement may be terminated at any time prior to the effective
time of the Merger, whether before or after approval by the shareholders of
the Company, as follows (a) by mutual consent of Parent, the Purchaser and the
Company; (b) by either Parent or the Company if: (i) any required approval of
the shareholders of the Company shall not have been obtained at any duly held
meeting of such shareholders; (ii) (x) as the result of the failure of any of
the conditions set forth in Section 14 of the Offer to Purchase, the Offer
shall have terminated or expired in accordance with its terms without the
Purchaser having purchased any Shares pursuant to the Offer or (y) subject to
certain exceptions, the Purchaser shall not have purchased any Shares pursuant
to the Offer within 90 days following the date of the Merger Agreement; (iii)
subject to certain exceptions, the Merger shall not have been consummated
before May 14, 1996; or (iv) any court of competent jurisdiction or any
governmental, administrative or regulatory authority, agency or body shall
have issued an order, decree or ruling or taken any other action permanently
enjoining, restraining or otherwise prohibiting the purchase of Shares
pursuant to the Offer or the Merger and such order, decree, ruling or other
action shall have become final and nonappealable; (c) by the Company if (i) to
the extent permitted, as described above, the Board of Directors of the
Company approves or recommends a superior proposal and (ii) the Company has
paid to Parent an amount in cash equal to the sum of the "Termination Fee"
plus all "Expenses", each as defined below; or (d) by Parent if Parent or the
Purchaser shall have received notice under (x) the Exon-Florio Amendment that
the Committee on Foreign Investment in the United States has determined to
investigate the Merger, any related transaction or Parent or the Purchaser or
(y) the HSR Act that the Federal Trade Commission or the Antitrust Division of
the Department of Justice has requested additional information concerning the
Offer, the Merger, any related transaction of Parent or the Purchaser,
extending the applicable waiting period under the HSR Act.
 
  A "Termination Fee" will be payable by the Company to Parent upon
termination of the Merger Agreement in the following circumstances: (i) The
Board of Directors of the Company withdraws its recommendation of the
 
                                       5
<PAGE>
 
Offer or recommends another offer, in which case the Company will be obligated
to pay a fee of $2 million and reimburse Parent for its expenses (including
underwriting fees in connection with the Rights Offering) up to $3 million
("Expenses"), for a total of up to $5 million; (ii) the Company materially
breaches its covenants in the Merger Agreement, in which case the fee will be
$2 million plus Expenses for a total of up to $5 million; (iii) the Company
materially breaches its representations in the Merger Agreement, both at
signing and upon termination of the Merger Agreement, in which case the fee
will be $2 million plus Expenses for a total of up to $5 million; (iv) there
has been a material adverse change or development in the DCIS Investigation
and senior management of the Company was personally involved in material
misconduct, in which case the fee will be $2 million plus Expenses, for a
total of $5 million; (v) the Company's representations in the Merger Agreement
were true at signing of the Merger Agreement, but become untrue in any
material respect thereafter, in which case the Company will be obligated to
reimburse Parent's Expenses up to $3 million; or (vi) there has been a
material adverse change or development in the DCIS Investigation and there are
discovered defects in the Company's products that are in excess of historical
levels and, in the aggregate (and after consideration of remedies reasonably
available to the United States in connection therewith) are reasonably likely
to have a material adverse effect on the Company, in which case Parent's
Expenses will be reimbursed up to $3 million.
 
  In connection with the Merger Agreement, each of the following directors of
the Company has submitted his written resignation, conditioned on and
effective as of the payment for Shares purchased in the Offer: Thomas F.
Leahy; David C. Malmberg; Stephen G. Shank; and William J. Cadogan. The Board
of Directors of the Company has appointed as directors of the Company,
conditioned on and effective as of such payment, the following representatives
of Parent: Geoffrey Wild; Donald J. Miller; and Daniel McL. Miller.
Accordingly, upon such payment, a majority of the Board of Directors of the
Company will be comprised of representatives of Parent.
 
  The Company's President and Chief Executive Officer, Robert W. Heller, has
indicated that he intends to remain employed by the Company for a period of at
least two years after the closing of the Offer. The Bidder, however, has not
offered or requested an employment agreement with Mr. Heller and has not
specified what his responsibilities will be.
 
  No dissenters' right are available to holders of Shares in connection with
the Offer. However, if the Merger is consummated, holders of Shares which have
not been tendered in the Offer will have certain rights under Sections
302A.471 and 302A.473 of the Minnesota Business Corporation Act ("MBCA") to
dissent and demand payment in cash of the fair value of their Shares. Such
rights, if the statutory procedures are complied with, could lead to a
judicial determination of the fair value required to be paid in cash to such
dissenting holders for their Shares. In making any such judicial determination
of the fair value, the court may take into account all factors the court finds
relevant, computed by any method or combination of methods that the court, in
its discretion, sees fit to use. The value so determined could be less than,
equal to or greater than the Offer price or the Merger consideration.
 
  The Merger will have to comply with any applicable federal law. In
particular, unless registration of the Shares under the Exchange Act is
terminated prior to such transaction, if the Purchaser acquires Shares
pursuant to the Offer and a business combination with the Company is
consummated more than one year after termination of the Offer or does not
provide for shareholders to receive cash for their Shares in an amount at
least equal to the price per Share paid pursuant to the Offer, the Purchaser
may be required to comply with Rule 13e-3 promulgated by the Commission under
the Exchange Act. If applicable, Rule 13e-3 would require, among other things,
that certain financial information concerning the Company and certain
information relating to the fairness of such business combination and the
consideration offered to minority shareholders be filed with the Commission
and distributed to minority shareholders prior to the consummation of any such
transaction.
 
  If for any reason the Merger is not consummated, Parent and the Purchaser
will evaluate their other alternatives. Such alternatives could include
purchasing additional Shares in the open market, in privately negotiated
transactions, in another tender or exchange offer or otherwise, or taking no
further action to acquire additional Shares. Any additional purchases of
Shares could be at a price greater or less than the price to be paid for
Shares in the Offer and could be for cash or other consideration.
Alternatively, the Purchaser may sell or otherwise dispose of any or all
Shares acquired pursuant to the Offer or otherwise. Such transactions may be
effected on terms and at prices then determined by Parent or the Purchaser,
which may vary from the price paid for Shares in the Offer.
 
                                       6

  Except as described above, the Purchaser and Parent have no present plans or
proposals that would relate to or result in any extraordinary corporate
transaction prior to the effectiveness of the Merger such as a merger,
reorganization or liquidation involving the Company or any of its
subsidiaries, a sale or transfer of a material amount of assets of the Company
or any of its subsidiaries, any change in the Company's Board of Directors or
management, any material change in the Company's capitalization or dividend
policy or any other material change in the Company's corporate structure or
business.
 
  Except as set forth in the preceding paragraphs of this Item 3 and as
described in Item 4 below, to the best knowledge of the Company, there are no
material contracts, agreements, arrangements or understanding, or any actual
or potential conflicts of interest, between the Company or its affiliates and
(i) the Company, its executive officers, directors or affiliates, or (ii) the
Bidder or its respective executive officers, directors, controlling person or
affiliates.
 
ITEM 4. THE SOLICITATION OR RECOMMENDATION
 
  (a) On December 2, 1994, the Company acquired Acsist Associates, Inc.
("Acsist"), a custom manufacturer of multilayer printed circuit boards and
plastic packages for semi-conductors. Following the acquisition, the Company
considered various means of expanding the business in order to realize the
potential of Acsist and of its other divisions and subsidiary. The directors
of the Company, at their meeting on December 6, 1994, discussed alternative
strategies for obtaining the technological and other resources required for
such an expansion, including seeking a partner who would provide technological
expertise, marketing capability or capital. At their meeting on February 7,
1995, the directors continued their considerations and Parent was identified
as a possible partner. Officers of the Company contacted Parent and on
February 24, 1995 visited its subsidiary's facilities in Spokane, Washington.
During this period, discussions with Parent focused on the possibility of a
partnership between Parent and Acsist and on the exchange of information about
technological and marketing matters and the respective operating philosophies
of Parent and the Company.
 
  Sporadic contacts with Parent continued through June 1995. Toward the end of
this period, Parent indicated its interest in discussing a possible
acquisition of the Company. In a telephone call at that time with a
representative of Parent, Robert W. Heller, the President and Chief Executive
Officer of the Company, acknowledged Parent's interest in acquiring the
Company but stated that he thought the Company's value might be greater than
any bid Parent might make. He suggested, as an alternative to an acquisition
of the entire Company, that Parent consider a substantial equity investment in
Acsist. In a telephone call several days later, Parent indicated that it
remained interested in all acquisition options. On June 29, 1995
representatives of Parent visited the Minnesota production facilities of the
Company and indicated that rather than any form of partnership or joint
development effort, Parent wished to discuss a possible acquisition of the
Company. As of June 28, 1995 the Company and Parent entered into an amendment
to the Confidentiality Agreement which had originally been executed between
Parent and Acsist on August 1, 1994 (i.e., prior to the acquisition of Acsist
by the Company) extending the confidentiality provisions and protections of
the Agreement to the Company. The directors of the Company had numerous
informal discussions during July 1995 concerning a possible transaction and
Parent proceeded to gather additional information about the Company. On July
28, 1995 the Company and Parent entered into a Common Interest/Joint Defense
Agreement which allowed Parent to conduct certain additional due diligence
inquiries into an investigation of the Company being conducted by the Defense
Criminal Investigation Service of the United States Department of Defense. See
Item 8 below.
 
  On July 31, 1995 the Board of Directors of the Company met and directed the
officers of the Company to proceed with their evaluation of possible financial
advisers to the Company and retention of an investment banker to render an
opinion as to the fairness, from a financial point of view, to the
shareholders of the Company of any proposal for acquisition of the Company
which might be received. Parent continued its due diligence investigation and
the Board met on August 8 to review the status of discussions. The Board also
appointed a Special Committee of Disinterested Directors, consisting of David
C. Malmburg, Stephen G. Shank and William J. Cadogan (comprising all of the
Company's "disinterested" directors as defined by the MBCA) (the "Special
Committee") to be prepared to consider as required under the MBCA any offer
which might be received from

the Bidder. After several days of discussion with Alex Brown & Sons
Incorporated ("Alex Brown"), on August 11 the Company retained Alex Brown to
be prepared to give a fairness opinion if requested.
 
  On August 12, 1995, representatives of the Bidder met in Minneapolis with
representatives of the Company to negotiate a merger agreement. On that day,
representatives of the Bidder indicated to Mr. Heller that the Bidder would be
prepared to acquire all Shares at a price of $21.50 per Share, subject, among
other things, to the Company's agreement to reimburse up to $4 million of the
Bidder's expenses in the event of termination of the Merger Agreement in
certain circumstances and to pay an additional $3.5 million fee to the Bidder
under certain of those circumstances (the "August 12 Proposal").
 
  On August 13, the Board and the Special Committee met separately to review
in detail the August 12 Proposal, the reasons for considering the possible
sale of the Company, the process engaged, the status of negotiations and a
preliminary report of Alex Brown that included information regarding the
reported price and trading activity for the Common Stock of the Company,
certain financial and stock market information for the Company compared to
similar information for certain other companies whose securities are publicly
traded and the financial terms of certain recent business combinations which
were deemed comparable in whole or in part. The Special Committee and the
Board of Directors of the Company directed Mr. Heller to negotiate further to
increase the price per Share and to lower the amount of fees and expenses to
be paid to the Bidder under certain circumstances.
 
   On August 14, the president of the Company received from the Bidder an
offer of $22.50 per Share (the "August 14 Offer"), subject, among other
things, to the Company's agreement to reimburse up to $3 million of the
Bidder's expenses in the event of termination of the Merger Agreement in
certain circumstances and to pay an additional $2 million fee to the Bidder
under certain of those circumstances.
 
  Later that afternoon, the Special Committee held a meeting to consider the
August 14 Offer at which all members of such committee were in attendance as
well as the Company's legal counsel and Alex Brown. At the meeting, the
Special Committee reviewed the terms of the August 14 Offer. A representative
of Alex Brown then outlined for the Company's Board of Directors Alex Brown's
valuation analysis and the methodology employed by Alex Brown in its analysis.
Alex Brown also gave the Special Committee its written opinion that the Offer
price of $22.50 per Share was fair to the shareholders of the Company from a
financial point of view. Based on the factors discussed below, the Special
Committee then unanimously approved the August 14 Offer as fair to the
shareholders of the Company and recommended that the Board approve the August
14 Offer.
 
  Immediately after the meeting of the Special Committee, the Board held a
meeting at which all the directors were present, as well as the Company's
legal counsel and Alex Brown. At such Meeting, the entire Board reviewed the
terms of the August 14 Offer and Alex Brown's analysis of the fairness
thereof. The Board acknowledged receipt of Alex Brown's fairness opinion. The
Board was advised that the Special Committee had unanimously approved the
August 14 Offer. Acting upon the unanimous recommendation of the Special
Committee, the Board then unanimously adopted resolutions approving the Offer,
the Merger and the Merger Agreement, determining that the terms of the Offer
and Merger are fair to, and in the best interests of, the Company and its
shareholders and recommending, subject to the terms and conditions set forth
in the Merger Agreement, that the Company's shareholders accept the Offer.
 
  During the evening of August 14, 1995, the Bidder and the Company entered
into the Merger Agreement. See Item 3 above for a description of the Merger
Agreement. Prior to the opening of business on August 15, 1995, the Bidder and
the Company issued a joint press release announcing the Merger and that the
Bidder would commence the Offer shortly.
 
  (b) A letter to shareholders communicating the Special Committee's and the
Board's recommendation and a press release announcing the signing of the
Merger Agreement are filed as Exhibits (a)(1) and (a)(2), respectively, and
are incorporated herein by reference. In considering the Offer and determining
to recommend its acceptance, the Special Committee and the Board in several
meetings analyzed the present and potential value of the Company's Common
Stock, the terms of the Offer and its fairness from a financial point of view.
The
 
                                       8
<PAGE>
 
Special Committee and the Board decided to recommend acceptance of the Offer
based on a number of factors, including:
 
    (1) The Board's familiarity with and review of the business, financial
  condition, results of operations and prospects of the Company, including
  the need for additional capital and management resources to complete the
  integration and maximize the potential of the Company's recently acquired
  Targ-It-Tronics and Acsist subsidiaries and the risks of attempting to
  expand the business of such subsidiaries.
 
    (2) The difficulty of obtaining additional capital or a strategic partner
  to expand the Acsist business in light of the pending DCIS Investigation of
  the Company (see Item 8 below).
 
    (3) The probable impact of the announcement of anticipated decreased
  earnings in the Company's fiscal quarter ending August 26, 1995 on the
  price of the Company's stock and on the valuation of the Company in a sale
  transaction (see Item 8 below).
 
    (4) A presentation by Alex Brown that included information regarding the
  reported price and trading activity for the Common Stock of the Company,
  certain financial and stock market information for the Company compared to
  similar information for certain other companies whose securities are
  publicly traded and the financial terms of certain recent business
  combinations which were deemed comparable in whole or in part. Alex Brown
  also delivered its written opinion that as of the date of such letter, the
  consideration to be received by the Company's shareholders was fair, from a
  financial point of view, to such shareholders. A copy of the written
  opinion of Alex Brown, setting forth the assumptions made, factors
  considered and limitations on the reviews, is attached as Exhibit (c)(2)
  hereto and is incorporated herein by reference;
 
    (5) The terms and conditions of the Merger Agreement, including the fact
  that Bidder's obligation to complete the Offer and the Merger are subject
  only to limited conditions and are not subject to a financing condition,
  and the fact that the Merger Agreement, although it contains certain
  expense reimbursement, termination payment and "no solicitation"
  provisions, does not prevent the Board of Directors, to the extent required
  by its fiduciary obligations as determined by a majority of its
  disinterested directors based on the written advice of counsel, from (i)
  providing information to and participating in discussions with a third
  party, and (ii) receiving and accepting a higher offer if one is
  forthcoming from any other party, and terminating the Merger Agreement.
 
    (6) The interests of the Company's employees, customers, suppliers and
  other constituencies.
 
ITEM 5. PERSONS RETAINED, EMPLOYED OR TO BE COMPENSATED
 
  On August 11, 1995, the Company entered into an engagement letter (the
"Letter Agreement") to engage Alex Brown to render, if requested, an opinion
as to the fairness, from a financial point of view, of the consideration
payable to the shareholders of the Company in connection with the proposed
transaction with the Bidder. The Company agreed to pay Alex Brown a fee of
$300,000 upon delivery of such opinion. The Company also agreed to pay Alex
Brown's reasonable out-of-pocket expenses, including fees and disbursements of
counsel, incurred in carrying out its duties under the Letter Agreement and to
indemnify Alex Brown against certain liabilities arising out of or in
connection with its engagement.
 
  Neither the Company nor any person acting on its behalf has retained any
other person to make solicitations or recommendations to shareholders with
respect to the Offer.
 
ITEM 6. RECENT TRANSACTIONS AND INTENT WITH RESPECT TO SECURITIES
 
  (a) To the best of the Company's knowledge, the only transaction by any
executive officer, director, affiliate or subsidiary of the Company in Company
Shares during the past sixty (60) days occurred on August 13, 1995 when Thomas
F. Leahy, a member of the Company's Board of Directors, gave an aggregate of
3,125 shares of Company Common Stock to his three children. Other directors
and/or executive officers may also give a portion of their Shares.
 
 
                                       9
<PAGE>
 
  (b) To the best of the Company's knowledge, its executive officers,
directors, their affiliates, and any recipients of a gift of Shares from the
foregoing presently intend to tender to Purchaser any Shares which are held of
record or which are beneficially owned by such persons.
 
ITEM 7. CERTAIN NEGOTIATIONS AND TRANSACTIONS BY THE SUBJECT COMPANY
 
  (a) On August 14, 1995, the Company and Bidder executed an Agreement and
Plan of Merger, a copy of which is filed with this Statement as Exhibit
(c)(1). See the response to Item 3(b) above for a description of the proposed
transaction.
 
  (b) Other than as described above in response to Item 3(b), there are no
transactions, board resolutions, agreements in principle or signed contracts
in response to the Offer, which relate to or would result in one or more of
the matters referred to in this Item 7, including (i) an extraordinary
transaction such as a merger or reorganization, involving the Company or its
subsidiaries; (ii) a purchase, sale or transfer of a material amount of assets
by the Company or its subsidiaries; (iii) a tender offer for or other
acquisition of securities by or of the Company; or (iv) any material change in
the present capitalization or dividend policy of the Company.
 
ITEM 8. ADDITIONAL INFORMATION TO BE FURNISHED
 
 DCIS Investigation
 
  The Defense Criminal Investigation Service ("DCIS") has commenced an
investigation into the Company. The DCIS is a part of the United States
Department of Defense and is responsible for investigating defense contract
misconduct committed by prime contractors or sub-contractors. The Company's
Specialty Products division produces printed circuit boards for the Company's
military and aerospace customers, including companies that are prime
contractors for the Department of Defense. The Company has never been a prime
contractor for the Department of Defense.
 
  The Company became aware of the investigation upon the execution of a search
warrant on June 28, 1995, which was followed by a subpoena for documents. The
DCIS Investigation is in its preliminary stages and no charges have been
filed. The Company does not know the likely duration of the investigation or
whether the Company or any of its officers or employees are likely to be
charged with any offense.
 
 Plans for the Company
 
  The Company's President and Chief Executive Officer, Robert W. Heller, has
indicated that he intends to remain employed by the Company for a period of at
least two years after the closing of the Offer. The Bidder, however, has not
offered or requested an employment agreement with Mr. Heller and has not
specified what his responsibilities will be.
 
  William J. Cadogan, Thomas F. Leahy, David C. Malmberg and Stephen G. Shank,
current Company directors, have submitted written resignations to the Company,
conditioned on and effective as of the closing of the Offer. The Board of
Directors of the Company has appointed three Purchaser designees as directors
of the Company, conditioned on and effective as of the closing of the Offer.
Such resignations and appointments are pursuant to the Merger Agreement. See
Annex A hereto.
 
  Following completion of the Offer, Parent intends to merge Purchaser with
and into the Company pursuant to and subject to certain conditions set forth
in the Merger Agreement.
 
  Parent has indicated that it presently intends that, for a period of one
year following the effective time of the proposed Merger, the employees of the
Company will continue to be provided with employee benefits that are in the
aggregate not materially less favorable to such employees than those presently
provided under the Company's current benefit plans; provided that the right is
reserved to review all employee benefit plans after the Merger and to make
such changes as are deemed appropriate in the judgment of Parent.

Purchase.

(1) The Merger Agreement provides that, effective upon closing of the Offer,
    all issued and outstanding stock options and warrants to purchase Company
    Common Stock will become immediately exercisable and the holders thereof
    will receive in cash from the Company an amount per share equal to $22.50
    minus the per share exercise price of such option. The options reflected
    in the above table each have a per share exercise price of $8.38 per
    share.
(2) The value of unexercised options represents the difference between the
    exercise price thereof and the closing price of the Common Stock on August
    27, 1994. The values were calculated only for "In-the-Money" options,
    which consist of those options whose exercise price is less than the
    market price per share on the last day of the fiscal year. Using the Offer
    price of $22.50 per share, the value of all options held by Messrs.
    Heller, Mueller, Kerrick and Kimball would be $155,320, $141,200, $141,200
    and $141,200, respectively.

COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION
 
  Compensation Committee Interlocks and Insider Participation. The Company is
engaged in a highly competitive industry. In order to succeed, the Company
believes that it must be able to attract and retain qualified executives. To
achieve this objective, the Company has structured an executive compensation
system tied to operating performance that the Company believes has enabled it
to attract and retain key executives. The Compensation Committee of the Board
of Directors was comprised during fiscal 1994 of Thomas F. Leahy, a former
officer and employee of the Company, David C. Malmberg and Stephen G. Shank,
both outside directors. All decisions by the Compensation Committee relating
to the compensation of the Company's executive officers are reviewed by the
full Board. Messrs. Leahy and Mueller are directors of Help Systems, Inc. and
in such capacity Mr. Mueller participates in the decision regarding
compensation of Mr. Leahy who receives remuneration as chairman of that
corporation.
 
  Compensation Policy. The goal of the Company's executive compensation policy
is to ensure that an appropriate relationship exists between executive pay and
the creation of shareholder value, while at the same time motivating and
retaining key employees. The compensation program is viewed in total
considering all of the component parts: base salary, annual performance
incentives, benefits, and long-term incentive opportunity in the form of stock
options. The annual compensation components consist generally of lower base
salaries than of comparative companies combined with higher incentive plans
based on the Company's financial performance. Long-term incentive is based on
the Company's financial performance. Long-term incentive is based on stock
performance through stock options. The Compensation Committee's position is
that stock ownership by management is beneficial in maintaining a proper
balance between management's and shareholders' interests in the enhancement of
shareholder value. Overall, the intent is to have more significant emphasis on
variable compensation components and less on fixed cost components. The
Committee believes this philosophy and structure are in the best interests of
the shareholders.
 
  Performance Measures. In evaluating annual executive compensation, the
Committee examines earnings per share, return on equity, sales growth and
total return to shareholders. These factors are compared with prior years'
performance, performance of other companies in the industry, and designated
Company goals.
 
  Fiscal 1994 Compensation. For fiscal 1994, the Company's executive
compensation program consisted of (i) base salary and (ii) an incentive bonus
based on achieving net income over a predetermined return to shareholders. In
1994, base salaries of Mr. Heller and the other executive offers were
increased as a result of comparing the Company's net profit and return on
investment to other companies in the printed circuit board industry. The
Committee believes that options and other stock based performance compensation
arrangements
 
                                      A-5
<PAGE>
 
are an effective incentive for managers to create value for shareholders since
the value of an option bears a direct relationship to the Company's stock
price.
 
  The Company's objective is to obtain a financial performance that achieves
financial goals over a period of time, including a return on equity of over
15%, and sales volume and earnings per share growth of 10% or more. The
Company's performance in fiscal 1994 included all time record sales levels and
slightly higher after tax income. In fiscal 1994, sales increased 14% and
earnings per share remained the same as the prior year. The Company's return
on equity decreased as a result of a higher equity and only slightly higher
net income. Mr. Heller's and the other executive officers' bonuses for fiscal
1994 reflect this decrease in return.
 
  The Committee believes that linking executive compensation to corporate
performance results in a better alignment of compensation with corporate goals
and shareholder interest. As performance goals are met or exceeded, resulting
in increased value to shareholders, executives are rewarded commensurately.
The Committee believes that compensation levels during fiscal 1994 adequately
reflect the Company's compensation goals and policies.

COMPARATIVE STOCK PERFORMANCE
 
  The following chart compares the yearly percentage change in the cumulative
total shareholder return on the Company's Common Stock during the five fiscal
years ended August 27, 1994 with the cumulative total return for the NASDAQ
Market Index and a peer group selected by the Company (the "SIC Peer Group
Index"). The SIC Peer Group Index includes the following NASDAQ companies:
Advance Circuits, Inc., Altron, Inc., Benchmark Electronics, Circuit Systems,
Inc., DDL Electronics, Electronic Associates Inc., Electronic Fab Technology,
Hadco CP, IEC Electronics CP, Jabil Circuit, Inc., Level One Comm, Inc., M-
Wave, Inc., Media Vision Technology, Merix CP, Micronics Computers, Inc., Park
Electrochemical CP, Parlex CP, Plexus CP, QLogic CP, Sanmina CP, SCI Systems
Inc., Sheldahl, Inc., Sigma Circuits, Inc., Solectron CP, U.S. Technologies,
Inc., and Video Display CP. All of the members of the peer group have the same
four-digit SIC (Standard Industrial Classification) code labeled 3672--Printed
Circuit Boards. The comparison assumes $100 was invested on August 27, 1989 in
the Company's Common Stock and in each of the foregoing indices and assumes
reinvestment of dividends.

COMPLIANCE WITH SECTION 16(A) OF THE EXCHANGE ACT
 
  Section 16(a) of the Securities Exchange Act of 1934 requires the Company's
executive officers and directors, and persons who own more than ten percent of
the Company's Common Stock, to file with the Securities and Exchange

Common Stock and other equity securities of the Company. Officers, directors
and greater than ten percent shareholders ("Insiders") are required by SEC

1994, all Section 16(a) filing requirements applicable to Insiders were
complied with except that one report covering one transaction was filed late
by David C. Malmberg, and Robert W. Heller was late filing a Form 5 reporting

Dear Fellow Advance Circuits, Inc. Shareholders:
 
  Johnson Matthey Public Limited Company ("Johnson Matthey") today initiated a
tender offer, subject to certain conditions described later in this letter, to
purchase your Advance Circuits, Inc. ("ACI") common stock at a price of $22.50
per share, net cash to tendering shareholders. The aggregate value of this
transaction, including amounts to "cash out" outstanding warrants and options,
is approximately $172 million. On August 14, 1995, the Board of Directors of
ACI and a Special Committee of Disinterested Directors each unanimously voted
to approve Johnson Matthey's tender offer and recommend that you tender your
ACI stock to Johnson Matthey pursuant to the tender offer.
 
  Since ACI's acquisition of Acsist Associates, Inc. in December 1994, the
Company has considered various means of expanding and leveraging the Acsist
business to its full potential, including raising additional capital or
seeking a corporate partner. When ACI discussed with Johnson Matthey a
partnering arrangement, they responded by indicating an interest in acquiring
all of ACI. This interest has continued despite the pending Department of
Defense investigation and projections of a disappointing fiscal 1995 fourth
quarter. Due to the significant risks inherent in ACI's pursuing its growth
strategy in light of these recent developments, the Board determined to accept
Johnson Matthey's offer.
 
  Our Board and its Special Committee of Disinterested Directors believe
Johnson Matthey's offer is fair, and they recommend that you accept the offer.
Alex. Brown & Sons Incorporated has rendered an opinion to the Board and the
Special Committee that the Johnson Matthey offer is fair to ACI's shareholders
from a financial point of view.
 
  Enclosed are the following materials relating to the Johnson Matthey tender
offer: (i) the Offer to Purchase dated August 21, 1995 prepared by Johnson
Matthey which states the basic terms of the Offer; (ii) the letter of
transmittal which must be filled out by you in order to tender your shares to
Johnson Matthey, with related documents; and (iii) a
Solicitation/Recommendation Statement on Schedule 14D-9 which has been
prepared by ACI in order, among other things, to explain more fully to you the
reasons ACI's Board recommends that you tender your ACI stock to Johnson
Matthey. These documents contain material information relevant to your
decision whether to tender your ACI stock to Johnson Matthey which it is not
feasible to provide in a letter of this length. We strongly encourage you to
read these materials before you decide whether to tender your shares.
 
  The Board recommends that you tender all of your ACI stock to Johnson
Matthey as promptly as possible, as I and my fellow directors and executive
officers intend to do. In order to do so, you should take the following steps:
 
    1. Complete, date and sign the enclosed letter of transmittal, and
 
    2. Arrange to send your completed letter of transmittal and the
  certificates representing your ACI stock (or, tender common shares pursuant
  to the procedures for book-entry transfer outlined in the letter of
  transmittal) and all other required documents to Chemical Mellon
  Shareholder Services at the appropriate address given in the letter of
  transmittal.
 
  In the alternative, you may ask your broker, dealer, commercial bank, trust
company or nominee to effect the transfer for you.

FOR IMMEDIATE RELEASE
 
                  JOHNSON MATTHEY TO ACQUIRE ADVANCE CIRCUITS
 
  MINNEAPOLIS, August 15, 1995.--Johnson Matthey plc and Advance Circuits,
Inc. announced today that they have signed a definitive merger agreement
providing for Johnson Matthey to acquire Advance Circuits. Under this
agreement, which has been approved by the boards of each company, an indirect
wholly owned US subsidiary of Johnson Matthey will be merged into Advance
Circuits. In connection with the merger, Johnson Matthey intends shortly to
commence a cash tender offer for all the outstanding shares of common stock of
Advance Circuits at $22.50 per share. Based upon 7.6 million Advance Circuits
common shares currently outstanding, the aggregate consideration to be paid in
the tender offer and the merger, including payment in respect of outstanding
stock options, will amount to approximately $171 million.
 
  The acquisition is not subject to a financing condition but is subject to
clearance under the Hart-Scott-Rodino Antitrust Improvements Act and to
certain other conditions.
 
  Advance Circuits, Inc. is a leading interconnect solution provider whose
products include complex multilayer printed circuit boards, flexible circuit
assemblies, semiconductor packages and other manufacturing services.
 
  In the nine months ended May 27, 1995, Advance Circuits had net sales of
$127.8 million and net income of $7.2 million ($0.98 per share). Advance
Circuits anticipates that its earnings for the fourth quarter ended August 26,
1995 will be substantially less than its earnings for the third quarter.
 
  Johnson Matthey, a United Kingdom public company, is a world leader in
advanced materials technology. Its principal businesses are the production of
electronic materials, specialty chemical and pharmaceutical compounds; the
manufacture of catalysts and pollution control systems; the refining,
fabrication and marketing of precious metals and the manufacturing of
decorative and specialized materials for the ceramics, plastics, paint, ink,
and construction industries. Johnson Matthey has operations in 29 countries
and employs 6,000 people. Its products are sold across the world to a wide
range of advanced technology industries. In the fiscal year ended March 31,
1995, Johnson Matthey's sales totaled approximately $3.5 billion.
 
  Commenting on this news, David Davies, Chairman and Chief Executive of
Johnson Matthey, said:
 
    "The acquisition of Advance Circuits will greatly expand the product
  range of Johnson Matthey's Electronic Materials business, in particular in
  the key emerging market of plastic laminate packaging. Johnson Matthey is
  committed to investing in superior technology and to serving our customers
  in markets worldwide. The acquisition of Advance Circuits further
  underlines this commitment."

  Robert Heller, Chairman and Chief Executive Officer of Advance Circuits,
said:
 
    "I am especially pleased with the merger because of Advance Circuits'
  enhanced ability to execute its global and semiconductor packaging
  strategies."
 
  Dillon, Read & Co. Inc. and Baring Brothers Limited are acting as financial
advisors for Johnson Matthey, with Dillon Read acting as dealer manager for
the offer. Alex. Brown & Sons Incorporated has rendered a fairness opinion for
Advance Circuits.
 
  The common stock of Advance Circuits is traded in the over-the-counter
market and prices are quoted on the Nasdaq National Market under the symbol
"ADVC."

    Section 1.1  The Offer.
                 ---------

          (a)  Provided that this Agreement has not been terminated in 
accordance with Section 8.1, Sub will, and Parent will cause Sub to, commence 
                -----------

of Company Common Stock tendered pursuant to the Offer will be subject only to 
the satisfaction of the conditions set forth in Annex I hereto (any of which may
be waived by Sub in its sole discretion) and to the terms and conditions of this
Agreement. Sub expressly reserves the right to modify the terms of the Offer, 
except that, without the consent of the Company (unless the Company takes any 
action permitted to be taken pursuant to the second sentence of Section 6.7(b)),
                                                                --------------

any of the conditions to Sub's obligation to purchase shares of Company Common 
Stock shall not be satisfied until such time as such conditions are satisfied or
waived, (ii) extend the Offer for any period required by any order, decree or 
ruling of, or any rule, regulation, interpretation or position of, any 
Governmental Entity (as defined in Section 4.4(a)) applicable to the Offer and

(iii) extend the Offer for any reason for a period of not more than five 
business days beyond the latest expiration date that would otherwise be 
permitted under clause (i) or (ii) of this sentence. The Offer will be made by 
means of an offer to purchase (the "Offer to Purchase") and related letter of 
                                    -----------------
transmittal containing the terms set forth in this Agreement and the conditions 
set forth in Annex I hereto. Subject to the terms of the Offer and this 
Agreement and the satisfaction or waiver of all the conditions of the Offer set 
forth in Annex I hereto as of the final expiration date of the Offer, Sub will, 
and Parent will cause Sub to, accept for payment and pay for all shares of 
Company Common Stock validly tendered and not withdrawn pursuant to the Offer as
soon as practicable after such expiration date.

          (b)  On the date of commencement of the Offer, Parent and Sub will 
file with the Securities and Exchange Commission (the "SEC") a Tender Offer

Statement on Schedule 14D-1 (together with all amendments and supplements 
thereto, the "Schedule 14D-1") with respect to the Offer. The Schedule 14D-1 
              --------------
will contain (including as an exhibit) or will incorporate by reference the 
Offer to Purchase (or portions thereof) and 

                                      -2-
<PAGE>
 
forms of the related letter of transmittal and summary advertisement (which 
Schedule 14D-1, Offer to Purchase, and other documents pursuant to which the 
Offer will be made, together with any supplements or amendments thereto, are 
referred to herein collectively as the "Offer Documents"). Parent and Sub will 
                                        ---------------
disseminate the Offer to Purchase, the related letter of transmittal and other 
Offer Documents to holders of shares of the Company Common Stock. Each of 
Parent, Sub and the Company will promptly correct any information provided by it
for use in the Offer Documents that becomes false or misleading in any material 
respect, and each of Parent and Sub will take all steps necessary to cause the 
Schedule 14D-1 as so corrected to be filed with the SEC and the other Offer 
Documents as so corrected to be disseminated to holders of shares of Company 
Common Stock, in each case as and to the extent required by applicable law. Sub 
will provide the Company and its counsel in writing with any comments Sub or its
counsel may receive from the SEC or its staff with respect to the Offer 
Documents promptly after the receipt of such comments. Parent, Sub and their 
counsel will provide the Company and its counsel with a reasonable opportunity 
to participate in all communications with the SEC and its staff, including any 
meetings and telephone conferences relating to the Offer Documents, the Offer, 
the Merger or this Agreement. 

          (c)  Sub will, and Parent will cause Sub to, designate a bank or trust
company reasonably acceptable to the Company as the paying agent for the Offer 
(the "Offer Paying Agent"). Sub agrees to deposit, and Parent agrees to cause 
      ------------------
Sub to deposit, with the Offer Paying Agent simultaneously with the consummation
of the Offer such funds as are necessary to make the cash payments required by 
the Offer. In no event shall any shareholder of the Company who has surrendered 
certificates representing Company Common Stock be entitled to receive interest 
on any of the funds to be received pursuant to the Offer. If a check is to be 
sent to a person other than the person in whose name a certificate for Company 
Common Stock surrendered in connection with the Offer is registered, it shall be
a condition of the transfer that the person requesting such transfer shall pay 
to the Offer Paying Agent any transfer or other taxes required by reason of the 
delivery of such check to a person other than the registered holder of the 
certificate surrendered, or shall establish to the satisfaction of the Offer 
Paying Agent that such tax has been paid or is not applicable. Notwithstanding 
the foregoing, neither the Offer Paying Agent nor any party hereto shall be 
liable to a holder of Company Common Stock for any amount paid to a public 
official pursuant to any applicable abandoned property, escheat or similar law.

          (d)  Sub and Parent will file with the Commissioner of Commerce of the
State of Minnesota any registration statement relating to the Offer required to 
be filed pursuant to Chapter 80B of the Minnesota Statutes.

counsel may receive from the SEC or its staff with respect to the Schedule 14D-9
promptly after the receipt of such comments.  The Company and its counsel will

the Paying Agent shall mail to each holder of record of a Certificate, other
than Parent, the Company, any Subsidiary of Parent or the Company and any holder
of Dissenting Company Common Stock (as defined below), (i) a letter of
transmittal (which shall specify that delivery shall be effected, and risk of
loss and title to the Certificates shall pass, only upon actual delivery of the
Certificates to the Paying Agent, and shall be in a form and have such other
provisions as Parent may reasonably specify) and (ii) instructions for use in
effecting the surrender of the Certificates in exchange for the Merger
Consideration.  Upon surrender of a Certificate for cancellation to the Paying
Agent or to such other agent or agents as may be appointed by the Surviving
Corporation, together with such letter of transmittal, duly executed, and such
other documents as may reasonably be required by the Paying Agent, the holder of
such Certificate shall be entitled to receive in exchange therefor the amount of
cash into which the shares of Company Common Stock theretofore represented by
such Certificate shall have been converted pursuant to Section 3.1, and the
                                                       -----------         
Certificates so surrendered shall forthwith be cancelled.  No interest will be
paid or will accrue on the cash payable upon the surrender of any Certificate.

Certificate so surrendered is registered, it shall be a condition of payment
that such Certificate shall be properly endorsed or otherwise in proper form for
transfer and that the person requesting such payment shall pay any transfer or
other taxes required by reason of the payment to a person other than the
registered holder of such Certificate or establish to the satisfaction of the
Surviving Corporation that such tax has been paid or is not applicable.  Until
surrendered as contemplated by this Section 3.2, each Certificate shall be
                                    -----------                           
deemed at any time after the Effective Time to represent only the right to
receive upon such surrender the amount of cash, without interest, into which the
shares of Company Common Stock theretofore represented by such Certificate shall
have been converted pursuant to Section 3.1.  Notwithstanding the foregoing,
                                -----------                                 
neither the Paying Agent nor any party shall be liable to a former shareholder

the shares of Company Common Stock in respect of which such deduction and
withholding was made by the Surviving Corporation or the Paying Agent.

issued and outstanding immediately prior to the Effective Time and that are held
by holders of such shares who have properly exercised dissenters' rights with
respect thereto in accordance with Sections 302A.471 and 302A.473 of the MBCA
(the "Dissenting Company Common Stock") will not be converted into or
      -------------------------------

such shares of Dissenting Company Common Stock will be entitled to receive
payment of the appraised value of such shares of Dissenting Company Common Stock
in accordance with the provisions of such Section 302A.473 unless and until such
holders fail to perfect or effectively withdraw or lose their rights to payment
under Section 302A.473 of the MBCA.  If, after the Effective Time, any such
holder fails to perfect or effectively withdraws or loses such right, such
shares of Dissenting Company Common Stock will thereupon be treated as if they
had been converted into and become exchangeable for, at the Effective Time, the
right to receive the Merger Consideration, without interest.  The Company will
give Parent prompt written notice of any notice of intent to demand payment of
the fair value of Company Common Stock under Section 302A.473 of the MCBA
received by the Company and, prior to the Effective Time, Parent and Sub will
have the right to direct all negotiations and proceedings with respect to such
demands.  Prior to the Effective Time, the Company will not, except with the

Corporation a bond in such sum as it may reasonably direct as indemnity against
any claim that may be made against the Surviving Corporation with respect to the
Certificate alleged to have been lost, stolen or destroyed.

     Section 3.8  Further Assurances.  If at any time after the Effective Time

were it to occur after the date of this Agreement or any material adverse change
with respect to the Company and its Subsidiaries and (ii) as of the date of this
Agreement, neither the Company nor any of its Subsidiaries has become a party to

be filed by the Company as an exhibit to its next Annual Report on Form 10-K.

     Section 4.9  Taxes.
                  ----- 

     (a) Except as disclosed in Section 4.9 of the Company Disclosure Letter,
                                -----------                                  
each of the Company and its Subsidiaries has duly filed all material Tax Returns
(as defined in Section 4.9(b)) required to be filed by it, all such Tax Returns
               --------------                                                  
are complete and accurate in all material respects and disclose all material
Taxes (as defined in Section 4.9(b)) required to be paid by the Company and its
                     --------------                                            
Subsidiaries, and the Company or its Subsidiaries has duly paid or caused to be
paid all Taxes shown to be due on such Tax Returns in respect of the periods
covered by such returns and has made provision adequate in all material respects
in the Company's financial statements for payment of all

                                     -17-
<PAGE>
 
Taxes anticipated to be payable in respect of all taxable periods or portions
thereof ending on or before the date hereof.  No Tax Returns filed by the
Company or its Subsidiaries have been "examined" by the Internal Revenue Service
(the "IRS") or other appropriate taxing authority.  Except as described in
      ---                                                                 
Section 4.9 of the Company Disclosure Letter, no issue or claim has been
-----------                                                             
asserted in writing for Taxes by any taxing authority for any prior period (and
to the best of the Company's knowledge no basis exists therefor), the adverse
determination of which would result in a deficiency which would have a material
adverse effect on the Company, other than those heretofore paid or provided for
in the Company's financial statements.  There are no outstanding agreements or
waivers extending the statutory period of limitation applicable to any Tax
Return of the Company or its Subsidiaries.  There are no material liens for
Taxes upon the assets of the Company or any of its Subsidiaries except liens
relating to current Taxes not yet due.  No transaction contemplated by this
Agreement is subject to withholding under Section 1445 of the Code and no stock
transfer Taxes, sales Taxes, use Taxes, real estate transfer Taxes, or other
similar Taxes will be imposed on Parent, Sub or the Company as a result of the
transactions contemplated by this Agreement under the laws of any jurisdiction
where the Company or any of its Subsidiaries does business.  All Taxes which the
Company or any of its Subsidiaries have been required by law to withhold or to
collect for payment have been duly withheld or collected and paid to the
appropriate taxing authority, except where the failure to so withhold or collect
such Taxes would not have a material adverse effect on the Company.  Neither the
Company nor any of its Subsidiaries is a party to any agreement, contract or
arrangement that could result, separately or in the aggregate, in the payment of
any "excess parachute payments" within the meaning of Section 280G of the Code.
Except as set forth in Section 4.9 of the Company Disclosure Letter, neither the
Company nor any of its Subsidiaries (i) has been a member of a group filing
consolidated returns for federal income tax purposes, or (ii) is a party to a
tax sharing or tax indemnity agreement or any other agreement of a similar
nature that remains in effect.

     (b) For purposes of this Agreement, the term "Taxes" means all taxes,
                                                   -----                  
charges, fees, levies or other assessments, including, without limitation,
income, gross receipts, excise, property, sales, use, transfer, license,
payroll, employment, withholding, environmental, capital stock, ad valorem,
alternate or add-on minimum and franchise taxes, imposed by the United States or
any state, local or foreign government or subdivision or agency thereof,
including any interest, penalties or additions thereto.  For purposes of this
Agreement, the term "Tax Return" means any report, return or other information
                     ----------                                               
or document required to be supplied to a taxing authority in connection with
Taxes.

     Section 4.10  Benefit Plans.  (a)  With respect to any "employee benefit
                   -------------                             ----------------
plan" (as defined in Section 3(3) of the Employee Retirement Income Security Act
----                                                                            
of 1974, as amended ("ERISA")), maintained or contributed to by the Company or
any

                                     -18-
<PAGE>
 
entity treated as a single employer under Section 414 of the Code ("ERISA
Affiliates") with the Company or with respect to which the Company or any of its
ERISA Affiliates is required to make any payment and any deferred compensation,
stock option, bonus, vacation or other such compensation arrangement to which
the Company is required to make any payment (collectively referred to as the
"Company Benefit Plans"), the Company has made available to Sub a true and
correct copy of (i) the most recent annual report (Form 5500) filed with the
IRS, (ii) such Company Benefit Plan, (iii) each trust agreement and group
annuity contract, if any, relating to such Company Benefit Plan and (iv) the
most recent actuarial report or valuation relating to a Company Benefit Plan
subject to Title IV of ERISA.  Each Company Benefit Plan (i) has been
administered in accordance with its terms in all material respects and (ii)
complies in form and has been administered in accordance with any and all
applicable state and federal laws, including ERISA and the Code, so as not to
give rise to any liability that would have a material adverse effect on the
Company and its Subsidiaries.  Each Company Benefit Plan and each trust that is
intended to qualify under Section 401(a) and 501(a) of the Code is so qualified
or, if not so qualified, the failure to be so qualified would not have a
material adverse effect on the Company.  Section 4.10 of the Company Disclosure
Letter sets forth a true and complete list of each material Company Benefit
Plan.

     (b) All contributions and premiums required by law or by the terms of such
employee benefit plan or any agreement relating thereto have been timely made
(without regard to any waiver granted with respect thereto), except where the
failure to make such contributions and premiums would not have a material
adverse effect on the Company.

     (c) With respect to the Company Benefit Plans, individually and in the
aggregate, no event has occurred, and neither the Company nor any of its ERISA
Affiliates has knowledge of any condition or set of circumstances in connection
with which the Company or any of its ERISA Affiliates is reasonably likely to be
subject to any liability that would have a material adverse effect on the
Company under ERISA, the Code or any other applicable law, including of any
"reportable event" (as defined in Section 4043(b) of ERISA) or any "prohibited
transaction" (as defined in Section 406 of ERISA and Section 4975(c) of the
Code).

     (d) With respect to the Company Benefit Plans, individually and in the
aggregate, there has not occurred any "accumulated funding deficiency" (within
the meaning of Section 412 of the Code), neither the Company nor any of its
ERISA Affiliates has failed to make a payment required under Section 412 of the
Code before the applicable due date, and there are no unfunded benefit
obligations which have not been accounted for by reserves, or otherwise properly
footnoted in accordance with generally accepted accounting principles, on the
financial statements of the Company or any of its ERISA Affiliates, which would
have a material adverse effect on the Company.

                                     -19-
<PAGE>
 
     (e) There have been no violations of ERISA with respect to the filing of
applicable returns, reports, documents or notices regarding any of the Company
Benefit Plans with the Secretary of Labor or the Secretary of Treasury or the
furnishing of such notices or documents to the participants or beneficiaries of
the Company Benefit Plans which have not subsequently been resolved or corrected
which would have a material adverse effect on the Company and its Subsidiaries.

     (f) To the Company's knowledge, there are no pending legal proceedings
which have been asserted or instituted against any Company Benefit Plan, the
assets of any such plan or the Company, or the plan administrator or fiduciary
of any Company Benefit Plan with respect to the operation of any such plan
(other than routine, uncontested benefit claims), and there are no facts or
circumstances which could form the basis for any such legal proceedings.  To the
Company's knowledge, neither the Company nor any fiduciary of any plan which is
not a multiemployer plan has engaged in a nonexempt prohibited transaction
described in Section 406 of ERISA or 4975 of the Code.

     (g) Each Company Benefit Plan complies in all material respects with all
applicable requirements of (i) the Age Discrimination in Employment Act of 1967,
as amended, and the regulations thereunder and (ii) Title VII of the Civil
Rights Act of 1964, as amended, and the regulations thereunder.  Each group
medical plan sponsored by the Company materially complies with the health care
continuation provisions of COBRA and (ii) the Medicare Secondary Payor
Provisions of Section 1826(b) of the Social Security Act, and the regulations
promulgated thereunder.

     (h) With respect to each Company Benefit Plan which is a multi-employer
plan (as described in Section 3(37) of ERISA), to the Company's knowledge, no
proceeding has been initiated to terminate any such plan with respect to which
the Company or any of its ERISA Affiliates has or has had an obligation to
contribute which would have a material adverse effect on the Company.  Neither
the Company or any of its ERISA Affiliates has any material liability
outstanding on account of a "partial withdrawal" (within the meaning of Sections
4205 and 4203, respectively, of ERISA) from any Company Benefit Plan which is a
multi-employer plan and, to the Company's knowledge, no such liability has been
asserted and there are no events or circumstances which would have a material
adverse effect on the Company and its Subsidiaries.  In the event that the
Company incurred a complete withdrawal under Section 4203 of ERISA, the
withdrawal liability arising under Section 4201 of ERISA with respect to each
Company Benefit Plan which is a multi-employer plan as a result thereof would
not have a material adverse effect on the Company.

     (i) The Company has no liability under Sections 4063, 4064, 4069 or 4212(c)
of ERISA.

                                     -20-

           (j) The Company has no obligations under any of the Company Benefit
Plans to provide health or life insurance benefits to its prior employees (or
their beneficiaries or dependents) for periods after termination of employment,
except as specifically required by Part 6 of Title I of ERISA.

           (k) Except as described in Section 4.10 of the Company Disclosure
Letter, neither the Company nor any of its Subsidiaries is a party to or bound
by any written, or to the Company's knowledge, oral:

           (i) employee collective bargaining agreement, employment
     agreement (other than employment agreements terminable by the Company or
     any of its Subsidiaries without premium or penalty on notice of 30 days or
     less under which the only monetary obligation of the Company or any of its
     Subsidiaries is to make current wage or salary payments and provide current
     fringe benefits), consulting, advisory or service agreement, deferred
     compensation agreement, confidentiality agreement or covenant not to
     compete;

          (ii) contract or agreement with any officer, director or
     employee (other than employment agreements disclosed in response to clause
     (i) or excluded from the scope of clause (i)), agent, or attorney-in-fact
     of the Company or any of its Subsidiaries; or

         (iii) stock option, stock purchase, bonus or similar incentive
     plan or agreement.

           (l) Except as set forth in Section 4.10 of the Company Disclosure
Letter, the Company and each of its Subsidiaries have complied in all material
respects with all applicable laws, rules and regulations which relate to prices,
wages, hours, discrimination in employment and collective bargaining and to its
operations and each is liable for any arrears of wages or any taxes or penalties
for failure to comply with any of the foregoing. The Company believes that its
and its Subsidiaries' relations with their employees are satisfactory. Neither
the Company nor any of its Subsidiaries are a party to, and none of such parties
are materially affected by or threatened with, any dispute or controversy with a
union or with respect to unionization or collective bargaining involving its
employees. Neither the Company nor any of its Subsidiaries are materially
affected by any dispute or controversy with a union or with respect to
unionization or collective bargaining involving any supplier or customer.
Section 4.10 of the Company Disclosure Letter sets forth a description of any
union organizing or election activities involving any non-union employees of the
Company and its Subsidiaries which have occurred since August 27, 1994 or, to
the knowledge of the Company, are threatened as of the date hereof.

                                     -21-

          (m) None of the Offer, the Merger or any other transaction
contemplated by this Agreement will, whether by itself or as a result of any
subsequent termination of employment, result in the acceleration of entitlement
to, or the payment of, any benefit or compensation.

    Section 4.11   Opinion of Financial Advisor.  The Company has received
                   ----------------------------                           
the opinion of Alex Brown, its financial advisor, to the effect that, as of
August 14, 1995, the consideration to be received in the Offer and the Merger,
taken as a whole, by the Company's shareholders is fair to the Company's
shareholders from a financial point of view, a copy of which opinion has been
delivered to Parent.

                   ----------------------------------------------      
Board of Directors of the Company and the Special Committee have each approved
the Offer, the Merger and this Agreement, such Special Committee has been duly
constituted pursuant to Section 302A.673 of the MBCA and consists only of
disinterested directors as defined therein and such approval by the Special
Committee is sufficient to render inapplicable to this Agreement, the Merger and
to the other transactions contemplated by this Agreement the restrictions on
business combinations (as defined in Section 302A.011 of the MBCA) contained in
Section 302A.673 of the MBCA.  Pursuant to Article 13 of the Company's Articles
of  Incorporation, Section 302A.671 of the MBCA is not applicable to the Offer,
the Merger or the other transactions contemplated by this Agreement.  Other than
Chapter 80B of the Minnesota Statutes, no other state takeover statute or
similar statute or regulation in any jurisdiction in which the Company or any of
its Subsidiaries does business, applies or purports to apply to the Offer, the
Merger or to this Agreement, or any of the transactions contemplated hereby or
thereby.

    Section 4.13   Intellectual Property. Section 4.13 of the Company
                   ---------------------  ------------

trademarks, trade names, copyright registrations, mask work registrations and

proprietary information ("Rights") necessary to the conduct of their business as
presently being conducted, except where the failure to have such licenses or
rights would not have a material adverse effect on the Company; (ii) neither the
Company nor any of its Subsidiaries has licensed any Rights to any third party;
(iii) the validity of such items and the title thereto of the Company and its
Subsidiaries has not been questioned in any litigation to which the Company or

                                     -22-
<PAGE>
 
have any claims to such effect been made to the Company or any of its
Subsidiaries; (iv) the conduct of the business of the Company and its
Subsidiaries as now conducted does not and will not conflict with Rights of
others in any way which has a material adverse effect on the Company and (v) no
proceedings are pending against the Company or any of its Subsidiaries nor, to
the Company's knowledge, are any proceedings threatened against the Company or
any of its Subsidiaries alleging any violation of Rights of any third party.
The Company does not know of (x) any use that has heretofore been or is now
being made of any Rights owned by the Company or any of its Subsidiaries, except
by the Company or any of its Subsidiaries or by an entity duly licensed by it to
use the same under an agreement described in Section 4.13 of the Company
                                             ------------               
Disclosure Letter or (y) any material infringement of any Right owned by or
licensed by or to the Company.  All Rights heretofore owned or held by any
employee or officer of the Company or any of its Subsidiaries and used in the
business of the Company or any of its Subsidiaries in any manner have been duly
and effectively transferred to the Company or such Subsidiary.  The consummation
of the Merger and the transactions contemplated hereby will not alter or impair
the rights and interests of the Company in any of the items listed in 
Section 4.13 of the Company Disclosure Letter, and the Surviving Corporation 
------------
will have the same rights and interests in such items as the Company will have
immediately prior to the Effective Time.

Closing Date), in lieu of such Employee Option, a payment equal to the aggregate
amount of cash, if any, determined under the preceding sentence; provided that
                                                                 --------     
such person shall not be entitled to receive any such amount if prior to the
Option Payment Date such person (x) terminates his employment by the Surviving
Corporation or any of its Subsidiaries, otherwise than as a result of death or

          (b) The Company shall use its best efforts to ensure that from and
after the Effective Time neither the Surviving Corporation nor any of its
Subsidiaries is or will be bound by any options, warrants, rights or agreements
which would entitle any person, other than Parent, Sub or their wholly owned
Subsidiaries, to beneficially own, or receive any payments (other than as
otherwise contemplated by Sections 3.1 and 3.6 and this Section 6.5) in respect
                          ------------     ---          -----------

for a period of one year following the Effective Time, the employees of the
Company will continue to be provided with employee benefits that are in the
aggregate not materially less favorable to such employees than those presently
provided under the Company's current benefit plans; provided that the right is
                                                    --------                  
reserved to review all employee benefit plans after the Effective Time and to

advisor or representative of the Company or any of its Subsidiaries to, (i)
solicit, initiate, or encourage the submission of, any takeover proposal, (ii)
enter into any agreement with respect to any takeover proposal

                                     -35-

or (iii) participate in any discussions or negotiations regarding, or furnish to
any person any information with respect to, or take any other action to
facilitate any inquiries or the making of any proposal that constitutes, or may
reasonably be expected to lead to, any takeover proposal; provided, however,
                                                          --------  ------- 
that prior to the acceptance for payment of shares of Company Common Stock
pursuant to the Offer, to the extent required by the fiduciary obligations of
the Board of Directors of the Company, as determined in good faith by a majority
of the disinterested members thereof based on the written advice of outside
counsel (a copy of which written advice shall be promptly furnished to Parent),
the Company may, in response to unsolicited requests therefor, participate in
discussions or negotiations with, or furnish information pursuant to an
appropriate confidentiality agreement to, any person.  Without limiting the
foregoing, it is understood that any violation of the restrictions set forth in
the preceding sentence by any officer, director or other management employee of
the Company or any of its Subsidiaries or any investment banker, attorney or
other advisor or representative of the Company or any of its Subsidiaries,
whether or not such person is purporting to act on behalf of the Company or
otherwise, shall be deemed to be a breach of this paragraph by the Company.  For
purposes of this Agreement, "takeover proposal" means any proposal, other than a
                             -----------------                                  
proposal by Parent or any of its affiliates, for a merger, consolidation, share
exchange, business combination or other similar transaction involving the
Company or any of its Subsidiaries or any proposal or offer (including, without
limitation, any proposal or offer to shareholders of the Company), other than a
proposal or offer by Parent or any of its affiliates, to acquire in any manner,
directly or indirectly, an equity interest in the Company or any of its
Subsidiaries, any voting securities of the Company or any of its Subsidiaries or
a substantial portion of the assets of the Company or any of its Subsidiaries.

          (b) Neither the Board of Directors of the Company nor any committee
thereof shall (i) withdraw or modify, or propose to withdraw or modify, in a
manner adverse to Parent or Sub, the approval or recommendation by the Board of
Directors of the Company or any such committee of the Offer, this Agreement or
the Merger or (ii) approve or recommend, or propose to approve or recommend, any
takeover proposal.  Notwithstanding the foregoing, the Board of Directors of the
Company, to the extent required by the fiduciary obligations thereof, as
determined in good faith by a majority of the disinterested members thereof
based on the written advice of outside counsel (a copy of which written advice
shall be promptly furnished to Parent), may approve or recommend (and, in
connection therewith, withdraw or modify its approval or recommendation of the
Offer, this Agreement or the Merger) a superior proposal and the Company may
take such actions as are contemplated by Rule 14e-2(a) and Rule 14d-9
promulgated under the Exchange Act.  For purposes of this Agreement, "superior
proposal" means a bona fide proposal made by a third party to acquire the
Company pursuant to a tender or exchange offer, a merger, a statutory share
exchange, a sale of all or substantially all its assets or otherwise on terms
which a majority of the disinterested

                                     -36-

members of the Board of Directors of the Company determines in its good faith
reasonable judgment (based on the advice of independent financial advisors) to
be more favorable to the Company and its shareholders than the Offer and the
Merger and for which financing, to the extent required, is then fully committed
or (based on the advice of independent financial advisors) is likely to be
obtained in a timely manner.

          (c) The Company promptly shall advise Parent orally and in writing of
any takeover proposal or any inquiry with respect to or which could lead to any
takeover proposal and the identity of the person making any such takeover
proposal or inquiry.  The Company will keep Parent fully informed of the status
and details of any such takeover proposal or inquiry.

     connection with the DCIS Investigation), (h) (but only if the condition set
     forth in such paragraph (h) was not satisfied on the date of this
     Agreement) or (i) of Annex I; or

          (ii) this Agreement is terminated pursuant to Section 8.1(c).

if, as a result of or in connection with the DCIS Investigation, there are
discovered any defects in the Company's products that are in excess of
historical levels and, in the aggregate (and after consideration of remedies
reasonably available to the United States in connection therewith), are
reasonably likely to have a material adverse effect on the Company) or (h) (but
only if the condition set forth in such paragraph (h) was satisfied on the date
of this Agreement) of Annex I (it being understood that in the event payment is
required under both paragraph (b)(i) and paragraph (c) of this Section 6.8,

upon demand for all out-of-pocket fees and expenses incurred or paid by or on
behalf of Parent or any of its affiliates in connection with the Offer, the
Merger or the consummation of any of the transactions contemplated by this
Agreement, including all fees and expenses of counsel, investment banking firms,
accountants, experts and consultants to Parent or any of its affiliates and all
fees and expenses payable of banks, investment banking firms and other financial
institutions and their respective counsel, accountants or agents in connection
with arranging or providing financing (including underwriting fees in connection
with Parent's contemplated rights offering); provided that all such out-of-
pocket fees and expenses shall not exceed $3 million (collectively, the
"Expenses").

          (d) The Company acknowledges that the agreements contained in
paragraphs (b) and (c) of this Section 6.8 are an integral part of the

transactions contemplated by this Agreement, and that, without these agreements,
Parent and Sub would not enter into this Agreement; accordingly, if the Company
fails to pay promptly any amount due pursuant to this Section 6.8 and, in order
                                                      -----------              
to obtain such payment, Parent or Sub commences a suit that results in a
judgment against the Company for any such amount, the Company shall pay to
Parent or Sub its costs and expenses (including attorneys' fees) in connection
with such suit, together with interest on the amount of the fee at the prime or
base rate of Bank of America NT&SA from the date such payment was due under this
Agreement.

and Sub, and Parent (or Sub, as the case may be) will give prompt notice to the
Company, of (a) the occurrence, or non-occurrence, of any event the occurrence,

representation or warranty contained in this Agreement that is qualified as to
materiality to be untrue or incorrect or any representation or warranty that is
not so qualified to be untrue or incorrect in any material respect or (ii) any
covenant, condition or agreement contained in this Agreement not to be complied

amend such agreements and instruments to permit the execution by the Company of
this Agreement, and the purchase of shares of Company Common Stock pursuant to
the Offer, and the consummation of the Merger, and to provide that such actions
do not constitute an event permitting the banks or lenders which are parties

instruments, and (b) in the event that such acceleration occurs prior to the
Merger, cooperate with Parent and Sub in arranging financing on terms reasonably
acceptable to Parent and Sub to finance any required repurchase or prepayment of

take such actions as are necessary so that the transactions contemplated hereby

to a Section, such reference will be to a Section of this Agreement unless
otherwise indicated. The headings contained in this Agreement are for reference
purposes only and will not affect in any way the meaning or interpretation of
this Agreement. Whenever the words "include," "includes" or "including" are used

the parties and delivered to the other parties, it being understood that all
parties need not sign the same counterpart.

any of the provisions of this Agreement were not performed in accordance with
their specific terms or were otherwise breached, irreparable damage would occur,
no adequate remedy at law would exist and damages would be difficult to
determine, and that the parties will be entitled to specific performance of the
terms hereof, in addition to any other remedy at law or equity.

    Section 9.10   Assignment.  Neither this Agreement nor any of the
                   ----------                                        
rights, interests or obligations hereunder will be assigned by any of the

written consent of the other parties.  Subject to the preceding sentence, this
Agreement will be binding upon, inure to the benefit of and be enforceable by
the parties and their respective successors and assigns.

                   ---------------------------------------------- 

          (a) Parent hereby irrevocably and unconditionally guarantees to the
Company the prompt and complete performance by Sub of each and every obligation
Sub may have under this Agreement.  At the Company's discretion, Parent may be
joined in any action, suit or proceeding brought by the Company against Sub in
connection with this Agreement and Parent shall conclusively be bound by the
judgment in any action, suit or proceeding brought by the Company against Sub as
if Parent were a party thereto.

          (b) For a period of one year from the date hereof, neither Parent nor
any of its affiliates shall, without the Company's consent, solicit the
employment of any person who, as of the date hereof, is a director, officer,
employee, independent sales agent or independent representative of the Company
or of any of its Subsidiaries;

                                     -47-

provided that the provisions of this Section 9.12(b) shall terminate upon the
Closing of the Offer.

          IN WITNESS WHEREOF, Parent, Sub and the Company have caused this
Agreement to be signed by their respective officers thereunto duly authorized as
of the date first written above.

                            Conditions to the Offer
                            -----------------------

          Notwithstanding any other term or provision of the Offer or this
Agreement, Sub will not be required to accept for payment or, subject to any

     success), (i)(A) challenging or seeking to, or which is reasonably likely
     to, make illegal, delay or otherwise directly or indirectly restrain or

     reasonably likely to materially adversely affect the Company or any of its
     Subsidiaries or Parent, Sub or any other affiliate of Parent or the value
     of the Company Common Stock;

          (b) there shall be any action taken, or any statute, rule, regulation,
     legislation, interpretation, judgment, order or injunction proposed,
     enacted, entered, enforced, promulgated, amended or issued with respect to,
     or deemed applicable to, (i) Parent, Sub or any other affiliate of Parent
     or the Company or any of its Subsidiaries or (ii) the Offer or the Merger
     by any government, legislative body or court, domestic, foreign or

     proceeding commenced by any Governmental Entity for the suspension or
     debarment of the Company or any of its Subsidiaries from doing business

     that any member of the senior management of the Company was involved
     personally in material misconduct or that there exist defects in the
     products of the Company or of any of its Subsidiaries, which defects are in
     excess of historical levels and, in the aggregate (and after consideration
     of remedies reasonably available to the United States in connection
     therewith), are reasonably likely to have a material adverse effect on the
     Company; or (vi) any civil action, suit or proceeding commenced by any
     Governmental Entity seeking legal or equitable relief;

     qualified shall not be true and correct in any material respect, in each
     case as if such representations and warranties were made as of such time;

          (i) the Company shall have failed to perform in any material respect
     any obligation or to comply in any material respect with any agreement or
     covenant of the Company to be performed or complied with by it under this
     Agreement; or

          (j) this Agreement shall have been terminated in accordance with its
     terms or the Offer shall have been amended or terminated with the consent
     of the Company;

which, in the good faith judgment of Sub, in any such case, and regardless of
the circumstances (including any action or inaction by Parent or any of its
affiliates) giving rise to any such condition, makes it inadvisable to proceed
with such acceptance for payment or payment.

          The foregoing conditions are for the sole benefit of Sub and Parent
and may be asserted by Sub regardless of the circumstances giving rise to any
such condition or may be waived by Sub in whole or in part at any time and from
time to time in its sole discretion.  The failure by Sub at any time to exercise
any of the foregoing rights will not be deemed a waiver of any such right, the
waiver of any such right with respect to particular facts and circumstances will
not be deemed a waiver with respect to any other facts and circumstances and
each such right will be deemed an ongoing right that may be

                                      -4-

asserted at any time and from time to time.  Any good faith determination by Sub
concerning the events described in this Annex I will be final and binding upon
all parties.

            [LOGO OF ALEX. BROWN & SONS INCORPORATED APPEARS HERE]

Advance Circuits, Inc.

Dear Sirs:
 
  Advance Circuits, Inc. ("Target" or the "Company"), Johnson Matthey Public
Limited Corporation ("Buyer") and ACI Acquisition Corporation, a Minnesota
corporation and an indirect, wholly-owned subsidiary of Buyer (the "Merger
Sub"), have entered into an Agreement and Plan of Merger dated August 14, 1995
(the "Agreement"). Pursuant to the Agreement, the Merger Sub will commence a
tender offer to purchase all outstanding shares of the common stock, $.10 par
value per share (the "Common Stock"), of Target at a price of $22.50 per
share, net to the seller in cash. The Agreement also provides that following
such tender offer, Merger Sub will be merged with and into Target (the
"Merger"), and that each then outstanding share of Common Stock, other than
shares held by Buyer or the Company, will be converted into the right to
receive $22.50 in cash. You have requested our opinion as to whether the
consideration to be received by the holders of the Common Stock pursuant to
the Agreement is fair, from a financial point of view, to such holders.
 
  Alex. Brown & Sons Incorporated, as a customary part of its investment
banking business, is engaged in the valuation of businesses and their
securities in connection with mergers and acquisitions, negotiated
underwritings, private placements and valuations for estate, corporate and
other purposes. We will receive a fee for rendering our opinion to the Board
of Directors.
 
  In connection with our opinion, we have reviewed the Agreement and certain
publicly available financial information concerning Target and certain
internal financial analyses and other information furnished to us by Target.
We have also held discussions with members of the senior management of Target
regarding the business and prospects of the Company. In addition, we have (i)
reviewed the reported price and trading activity for the Common Stock of
Target, (ii) compared certain financial and stock market information for
Target with similar information for certain other companies whose securities
are publicly traded, (iii) reviewed the financial terms of certain recent
business combinations which we deemed comparable in whole or in part and (iv)
performed such other studies and analyses and considered such other factors as
we deemed appropriate.
 
  We have assumed and relied upon, without independent verification, the
accuracy and completeness of the information furnished to us or otherwise
reviewed by or discussed with us for purposes of this opinion. With respect to
the financial projections used in our analyses and the information relating to
the prospects of Target, we have assumed that such information reflects the
best currently available estimates and judgments of management of Target as to
the likely future financial performance of Target. In addition, we have not
made an independent evaluation or appraisal of the assets of Target, nor have
we been furnished with any such evaluation or appraisal. Our opinion is based
on market, economic and other conditions as they exist and can be evaluated as
of the date of this letter.
 
  The opinion expressed herein is for the information of the Board of
Directors of the Company. This letter does not constitute a recommendation by
us to any stockholder of Target as to how such stockholder should vote with
respect to the Merger. We hereby consent, however, to the inclusion of this
opinion as an exhibit to any proxy or tender offer document distributed in
connection with this Merger. This letter should not be used for any other
purpose without our prior written consent.

  Based upon and subject to the foregoing, it is our opinion that, as of the
date of this letter, the consideration to be received by the holders of the
Common Stock pursuant to the Agreement is fair, from a financial point of
view, to such holders.
 
                                          Very truly yours,
