To The Holders of Common Stock of
PRAEGITZER INDUSTRIES, INC.

                                  INTRODUCTION

    T MERGER SUB (OR), Inc., an Oregon corporation ("Purchaser"), a wholly owned
subsidiary of Sigma Circuits, Inc. ("Parent"), a Delaware Corporation and an
indirect wholly owned subsidiary of Tyco International Ltd., a Bermuda company
("Tyco"), hereby offers to purchase all outstanding shares (the "Shares") of
common stock of Praegitzer Industries, Inc., an Oregon corporation (the
"Company"), at $5.50 per Share, net to the seller in cash, upon the terms and
subject to the conditions set forth in this Offer to Purchase and in the related
Letter of Transmittal (which together constitute the "Offer"). Tyco has fully
and unconditionally guaranteed the Offer.

    Tendering shareholders will not be obligated to pay brokerage fees or
commissions or, subject to Instruction 6 of the Letter of Transmittal, stock
transfer taxes on the purchase of Shares by Purchaser pursuant to the Offer.
However, any tendering shareholder or other payee who fails to complete and sign
the Substitute Form W-9 that is included in the Letter of Transmittal may be
subject to a required backup federal income tax withholding of 31% of the gross
proceeds payable to such shareholder or other payee pursuant to the Offer. See
Section 2. The Purchaser will pay all charges and expenses of Morrow &
Co., Inc., as Information Agent (the "Information Agent"), and ChaseMellon
Shareholder Services, L.L.C., as Depositary (the "Depositary"), incurred in
connection with the Offer. See Section 17.

    The Offer is conditioned upon, among other things, there being validly
tendered and not withdrawn prior to the expiration of the Offer at least that
number of shares which would constitute 51% of the outstanding shares on a
diluted basis ("the Minimum Condition"). The majority shareholder of the Company
who owns 8,119,375 shares (constituting approximately 53.0% of the outstanding
shares on a diluted basis) has agreed to tender these shares in the offer. If
the majority shareholder is unable to tender 2,656,500 of these shares (the
"Pledged Shares") in the offer (constituting approximately 17.4% of the
outstanding shares on a diluted basis) because the Pledged Shares are not
released from certain pledge arrangements before the consummation of the Offer,
the majority shareholder has agreed to sell to the purchaser the Pledged Shares
following consummation of the offer upon the release of the Pledged Shares from
the pledge arrangements to which they are subject. The Offer is also subject to
certain other terms and conditions set forth in Section 15.

    The Offer is being made pursuant to an Agreement and Plan of Merger, dated
as of October 26, 1999 (the "Merger Agreement"), among Parent, Purchaser and the
Company, and the related guarantee of Tyco. The Merger Agreement provides, among
other things, that upon the terms and subject to the conditions therein, as soon
as practicable after the consummation of the Offer, Purchaser will be merged
with and into the Company (the "Merger"), with the Company being the corporation
surviving the Merger (the "Surviving Corporation"). At the effective time of the
Merger (the "Effective Time"), each outstanding Share (other than Shares with
respect to which appraisal rights are properly exercised under the Oregon
Business Corporation Act (the "OBCA") ("Dissenting Shares") or owned by Tyco,
Parent, Purchaser or any other subsidiary of Tyco) will be converted into and
represent the right to receive $5.50 in cash or any higher price that may be
paid per Share in the Offer (the "Per Share Amount"), without interest. See
Section 13.

    THE BOARD OF DIRECTORS OF THE COMPANY HAS DETERMINED THAT THE OFFER AND THE
MERGER ARE FAIR TO, AND IN THE BEST INTERESTS OF, THE COMPANY AND ITS
SHAREHOLDERS, HAS APPROVED THE MERGER AGREEMENT, THE OFFER AND THE MERGER AND
RECOMMENDS THAT THE COMPANY'S SHAREHOLDERS ACCEPT THE OFFER AND TENDER THEIR
SHARES PURSUANT TO THE OFFER.

    Adams, Harkness & Hill, Inc., one of the Company's financial advisors
("AHH"), has delivered to the Company's Board of Directors its written opinion
that the aggregate consideration to be received by the

                                       4
<PAGE>
shareholders of the Company pursuant to the Merger Agreement is fair to such
shareholders from a financial point of view. A copy of such opinion is contained
in the Company's Solicitation/Recommendation Statement on Schedule 14D-9 which
is being distributed to the Company's shareholders herewith.

    The Merger Agreement provides that, promptly upon the purchase of Shares
pursuant to the Offer, Parent will be entitled to designate such number of
directors, rounded up to the next whole number, on the Board of Directors of the
Company as will give Parent, subject to compliance with Section 14(f) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), representation
on the Board of Directors equal to the product of (a) the total number of
directors on the Board of Directors and (b) the percentage that (i) the number
of Shares beneficially owned by Parent or any of its affiliates following
consummation of the Offer bears to (ii) the total number of Shares outstanding.
The Company shall, upon request by Parent, promptly increase the size of the
Board of Directors and/or exercise its reasonable best efforts to secure the
resignations of such number of directors as is necessary to enable Parent's
designees to be elected to the Board of Directors and shall cause Parent's
designees to be so elected. See Section 13.

    The Company has informed Purchaser that as of October 22, 1999,
(i) 13,129,751 Shares were issued and outstanding, (ii) no shares of Preferred
Stock were issued or outstanding, (iii) 1,809,550 shares of the Company's common
stock were reserved for future issuance pursuant to outstanding options (561,750
shares at exercise prices below $5.50 per share), (iv) no shares of common stock
were reserved for future issuance pursuant to the Company Stock Purchase Plan,
(v) 46,333 shares of common stock were reserved for future issuance upon
exercise of certain warrants at $12.00 per share, (vi) 1,743,559 shares of
common stock were reserved for future issuance upon exercise of the conversion
rights contained in that certain Deferral Loan and Lease Modification Agreement
dated as of October 12, 1999 among the Company and the lenders and lessors named
therein (the "Deferral Agreement") (these conversion rights cannot be exercised
if the Offer is completed before March 31, 2000) and (vii) 1,381,382 shares of
common stock were reserved for issuance upon the conversion of the Company's 9%
Convertible Subordinated Notes due December 29, 2008 (the "Notes") at a
conversion price of $8.325 per share. As used herein "outstanding shares on a
diluted basis" means the outstanding shares of the Company's common stock on a
fully diluted basis excluding shares issuable upon exercise of conversion rights
pursuant to the Deferral Agreement and options that are not exercisable prior to
March 1, 2000.

    If the Minimum Condition is satisfied, Purchaser will have sufficient voting
power to approve the Merger, even if no other shareholder votes in favor of the
Merger. Under the OBCA, if a parent corporation owns at least 90% of the shares
of each class of shares of a subsidiary corporation, the parent can merge with
the subsidiary in a "short form" merger without a vote of shareholders. Assuming
that Purchaser acquires 90% or more of the Shares, Purchaser would be able to
effect the Merger pursuant to the short form merger provisions of the OBCA,
without the action of any other shareholder of the Company.

    THIS OFFER TO PURCHASE AND THE RELATED LETTER OF TRANSMITTAL CONTAIN
IMPORTANT INFORMATION AND SHOULD BE READ IN THEIR ENTIRETY BEFORE ANY DECISION
IS MADE WITH RESPECT TO THE OFFER.

                                THE TENDER OFFER

    1. TERMS OF THE OFFER; EXTENSION OF TENDER PERIOD; TERMINATION;
AMENDMENTS.  Upon the terms and subject to the conditions of the Offer
(including, if the Offer is extended or amended, the terms and conditions of any
such extension or amendment), Purchaser will accept for payment and pay for all
Shares which are validly tendered on or prior to the Expiration Date (as
hereinafter defined) and not theretofore withdrawn as permitted by Section 3.
The term "Expiration Date" means 12:00 Midnight, New York City time, on Tuesday,
November 30, 1999, unless and until Purchaser (subject to the terms and
conditions of the Merger Agreement) shall have extended the period of time for
which the Offer is open, in which event the term "Expiration Date" shall mean
the latest time and date at which the Offer, as so extended by Purchaser, shall
expire.

    The Offer is conditioned upon, among other things, the satisfaction of the
Minimum Condition. Subject to the provisions of the Merger Agreement, Purchaser
reserves the unilateral right (but shall not be obligated) to waive or reduce
the Minimum Condition or to waive any or all of the conditions of the Offer
other than the Minimum Condition. If, by 12:00 Midnight, New York City time, on
Tuesday, November 30, 1999, or any subsequent Expiration Date, any or all of the
conditions to the Offer have not been satisfied or waived, subject to the
provisions of the Merger Agreement, Purchaser may elect to (i) terminate the
Offer and return all tendered Shares to tendering shareholders, (ii) waive all
of the unsatisfied conditions (including, with the consent of the Company, the
Minimum Condition) and, subject to any required extension, purchase all Shares
validly tendered by the Expiration Date and not withdrawn, (iii) extend the
Offer and, subject to the right of shareholders to withdraw Shares until the
adjusted Expiration Date, retain the Shares that have been tendered until the
expiration of the Offer as extended or (iv) delay acceptance for payment of, or
payment for, the Shares, subject to complying with applicable law, until the
satisfaction or waiver of the conditions of the Offer. Purchaser acknowledges
that its reservation of the right to delay payment for Shares that it has
accepted for payment is limited by Rule 14e-1(c) under the Exchange Act, which
requires Purchaser to pay the consideration offered or return the Shares
tendered promptly after the termination or withdrawal of the Offer. See
Section 15.

    Under the terms of the Merger Agreement, Purchaser may not, without the
prior written consent of the Company, (i) impose conditions to the Offer in
addition to the Offer Conditions (as defined below), (ii) modify or amend the
Offer Conditions or any other term of the Offer in a manner adverse to the
holders of Shares, (iii) waive or amend the Minimum Condition, (iv) reduce the
number of Shares subject to the Offer, (v) reduce the Per Share Amount,
(vi) except as provided in the following paragraph, extend the Offer, if all of
the Offer Conditions are satisfied or waived, or (vii) change the form of
consideration payable in the Offer.

    Notwithstanding the foregoing, Purchaser may, without the consent of the
Company, extend the Offer at any time, and from time to time, (i) if at the then
scheduled expiration date of the Offer any of the conditions to Purchaser's
obligation to accept for payment and pay for Shares (the "Offer Conditions")
shall not have been satisfied or waived, until such time as such conditions are
satisfied or waived; (ii) for any period required by any rule, regulation,
interpretation or position of the Securities and Exchange Commission (the
"Commission") or its staff applicable to the Offer; or (iii) if all Offer
Conditions are satisfied or waived but the number of Shares tendered is less
than 90% of the then outstanding number of Shares, for an aggregate period of
not more than 10 business days (for all such extensions) beyond the latest
expiration date that would be permitted under clause (i) or (ii) of this
sentence.

    Subject to the applicable regulations of the Commission and the provisions
of the Merger Agreement, Purchaser also expressly reserves the rights, in its
sole discretion, at any time or from time to time, (i) to extend the Offer and
adjust the Expiration Date, (ii) to terminate the Offer if any of the conditions
referred to in Section 15 have not been satisfied or upon the occurrence of any
of the events specified in Section 15 and (iii) to waive any condition or
otherwise amend the Offer in any respect, in each case by giving oral or written
notice of such extension, termination, waiver or amendment to the Depositary and
by

                                       6
<PAGE>
making a public announcement thereof. If Purchaser accepts for payment any
Shares pursuant to the terms of the Offer, it will accept for payment all Shares
validly tendered prior to the Expiration Date and not withdrawn, and will
promptly pay for all Shares so accepted for payment. Purchaser acknowledges that
notwithstanding anything to the contrary contained in the Offer, Purchaser shall
not be required to pay for the Shares and may terminate or amend the Offer only
if, prior to the Expiration Date, any of the conditions referred to in
Section 15 have not been satisfied or waived, or if any of the events specified
in Section 15 have occurred.

    The rights reserved by Purchaser in the preceding paragraph are in addition
to Purchaser's rights pursuant to Section 15. Any extension, delay, termination
or amendment of the Offer will be followed as promptly as practicable by public
announcement thereof, such announcement in the case of an extension to be issued
no later than 9:00 a.m., New York City time, on the next business day after the
previously scheduled Expiration Date, in accordance with the public announcement
requirements of Rule 14e-1(d) under the Exchange Act. Subject to applicable law
(including Rules 14d-4(c) and 14d-6(d) under the Exchange Act, which require
that any material change in the information published, sent or given to
shareholders in connection with the Offer be promptly disseminated to
shareholders in a manner reasonably designed to inform shareholders of such
change), and without limiting the manner in which Purchaser may choose to make
any public announcement, Purchaser shall have no obligation to publish,
advertise or otherwise communicate any such public announcement other than by
making a release to the Dow Jones News Service.

    If Purchaser makes a material change in the terms of the Offer or the
information concerning the Offer, or if it waives a material condition of the
Offer (including, subject to the Merger Agreement, the Minimum Condition),
Purchaser will disseminate additional tender offer materials (including by
public announcement as set forth above) and extend the Offer to the extent
required by Rules 14d-4(c), 14d-6(d) and 14e-1 under the Exchange Act. The
minimum period during which an offer must remain open following material changes
in the terms of the Offer, other than a change in price, percentage of
securities sought or inclusion of or change to a dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality, of the
changes. In the Commission's view, an offer should remain open for a minimum of
five business days from the date the material change is first published, sent or
given to shareholders, and, if material changes are made with respect to
information that approaches the significance of price and share levels, a
minimum of ten business days may be required to allow for adequate dissemination
and investor response. With respect to a change in price or, subject to certain
limitations, a change in the percentage of securities sought or inclusion of or
change to a dealer's soliciting fee, a minimum ten business day period from the
date of such change is generally required to allow for adequate dissemination to
shareholders. Accordingly, if, prior to the Expiration Date, Purchaser decreases
the number of Shares being sought or increases or decreases the consideration
offered pursuant to the Offer, and if the Offer is scheduled to expire at any
time earlier than the period ending on the tenth business day from the date that
notice of such increase or decrease is first published, sent or given to
shareholders, the Offer will be extended at least until the expiration of such
ten business day period. For purposes of the Offer, a "business day" means any
day other than a Saturday, Sunday or a federal holiday and consists of the time
period from 12:01 a.m. through 12:00 midnight, New York City time.

    In connection with the Offer, the Company has provided or will provide
Purchaser with the names and addresses of all record holders of Shares and
security position listings of Shares held in stock depositories. This Offer to
Purchase, the related Letter of Transmittal and other relevant materials will be
mailed to registered holders of Shares and will be furnished to brokers,
dealers, commercial banks, trust companies and similar persons whose names, or
the names of whose nominees, appear on the shareholder list or, if applicable,
who are listed as participants in a clearing agency's security position listing,
for subsequent transmittal to beneficial owners of Shares.

    2. PROCEDURE FOR TENDERING SHARES.  Except as set forth below, in order for
Shares to be validly tendered pursuant to the Offer, the Letter of Transmittal
(or a facsimile thereof), properly completed and

                                       7
<PAGE>
duly executed, together with any required signature guarantees, or an Agent's
Message (as hereinafter defined) in connection with a book-entry transfer of
Shares, and any other documents required by the Letter of Transmittal, must be
received by the Depositary at one of its addresses set forth on the back cover
of this Offer to Purchase on or prior to the Expiration Date, and either
(i) certificates representing tendered Shares must be received by the
Depositary, or such Shares must be tendered pursuant to the procedure for
book-entry transfer set forth below (and confirmation of receipt of such
delivery must be received by the Depositary), in each case on or prior to the
Expiration Date, or (ii) the guaranteed delivery procedures set forth below must
be complied with. No alternative, conditional or contingent tenders will be
accepted.

    SIGNATURE GUARANTEES.  No signature guarantee is required on the Letter of
Transmittal (i) if such Letter of Transmittal is signed by the registered holder
of the Shares tendered therewith, unless such holder has completed either the
box entitled "Special Delivery Instructions" or the box entitled "Special
Payment Instructions" in the Letter of Transmittal, or (ii) if Shares are
tendered for the account of a firm that is a member in good standing of the
Security Transfer Agent's Medallion Program, the New York Stock Exchange
Medallion Signature Program or the Stock Exchange Medallion Program (each being
hereinafter referred to as an "Eligible Institution"). See Instruction 1 of the
Letter of Transmittal.

    If a certificate representing Shares is registered in the name of a person
other than the signatory of the Letter of Transmittal (or a facsimile thereof),
or if payment is to be made, or Shares not accepted for payment or not tendered
are to be returned to a person other than the registered holder, the certificate
must be endorsed or accompanied by an appropriate stock power, in either case
signed exactly as the name(s) of the registered holder(s) appears on the
certificate, with the signature(s) on the certificate or stock power guaranteed
by an Eligible Institution. If the Letter of Transmittal or stock powers are
signed or any certificate is endorsed by trustees, executors, administrators,
guardians, attorneys-in-fact, officers of corporations or others acting in a
fiduciary or representative capacity, such persons should so indicate when
signing and, unless waived by Purchaser, proper evidence satisfactory to
Purchaser of their authority so to act must be submitted. See Instruction 5 of
the Letter of Transmittal.

    BOOK-ENTRY TRANSFER.  The Depositary will establish accounts with respect to
the Shares at The Depository Trust Company ("DTC") for purposes of the Offer
within two business days after the date of this Offer to Purchase, and any
financial institution that is a participant in DTC's system may make book-entry
delivery of the Shares by causing DTC to transfer such Shares into the
Depositary's account in accordance with DTC's procedure for such transfer.
However, although delivery of Shares may be effected through book-entry transfer
at DTC, a properly completed and duly executed Letter of Transmittal (or
facsimile thereof), with any required signature guarantees, or an Agent's
Message and any other required documents, must, in any case, be transmitted to
and received by the Depositary at one of its addresses set forth on the back
cover of this Offer to Purchase prior to the Expiration Date, or the guaranteed
delivery procedures described below must be complied with. The term "Agent's
Message" means a message transmitted through electronic means by DTC to, and
received by, the Depositary and forming a part of a book-entry confirmation,
which states that DTC has received an express acknowledgment from the
participant in DTC tendering the Shares that such participant has received, and
agrees to be bound by, the terms of the Letter of Transmittal. Delivery of
documents to DTC in accordance with DTC's procedures does not constitute
delivery to the Depositary.

    GUARANTEED DELIVERY.  If a shareholder desires to tender Shares pursuant to
the Offer and such shareholder's certificates representing Shares are not
immediately available (or the procedures for book-entry transfer cannot be
completed on a timely basis) or time will not permit all required documents to
reach the Depositary prior to the Expiration Date, such Shares may nevertheless
be tendered, provided that all of the following conditions are satisfied:

        (a) such tender is made by or through an Eligible Institution;

                                       8
<PAGE>
        (b) the Depositary receives, prior to the Expiration Date, a properly
    completed and duly executed Notice of Guaranteed Delivery, substantially in
    the form provided by Purchaser; and

        (c) the certificates representing all tendered Shares in proper form for
    transfer (or confirmation of a book-entry transfer of such Shares into the
    Depositary's account at DTC), together with a properly completed and duly
    executed Letter of Transmittal (or facsimile thereof) with any required
    signature guarantees (or, in connection with a book-entry transfer, an
    Agent's Message) and any other documents required by the Letter of
    Transmittal are received by the Depositary within three trading days after
    the date of such Notice of Guaranteed Delivery. A "trading day" is any day
    on which The Nasdaq Stock Market is open for business.

    The Notice of Guaranteed Delivery may be delivered by hand, or may be
transmitted by telegram, telex, facsimile transmission or mail, to the
Depositary and must include a guarantee by an Eligible Institution in the form
set forth in such Notice of Guaranteed Delivery.

    In all cases, payment for Shares tendered and accepted for payment pursuant
to the Offer will be made only after timely receipt by the Depositary of
(i) certificates representing such Shares (or timely confirmation of a
book-entry transfer of such Shares into the Depositary's account at DTC),
(ii) properly completed and duly executed Letter(s) of Transmittal (or
facsimile(s) thereof), together with any required signature guarantees (or, in
connection with a book-entry transfer, an Agent's Message) and (iii) any other
documents required by the Letter of Transmittal.

    The method of delivery of all documents, including certificates for Shares,
is at the option and risk of the tendering shareholder, and the delivery will be
deemed made only when actually received by the Depositary. If delivery is by
mail, registered mail with return receipt requested, properly insured, is
recommended. In all cases, sufficient time should be allowed to ensure timely
delivery.

    DETERMINATION OF VALIDITY.  All questions as to the form of documents and
the validity, eligibility (including time of receipt) and acceptance for payment
of any tendered Shares will be determined by Purchaser in its sole discretion,
and its determination shall be final and binding on all parties. Purchaser
reserves the absolute right to reject any or all tenders of any Shares that it
determines are not in appropriate form or the acceptance for payment of or
payment for which may, in the opinion of Purchaser's counsel, be unlawful.
Purchaser also reserves the absolute right to waive any defect or irregularity
in any tender with respect to any particular Shares or any particular
shareholder, and Purchaser's interpretation of the terms and conditions of the
Offer (including the Letter of Transmittal and the Instructions thereto) will be
final and binding on all parties. No tender of Shares will be deemed to have
been validly made until all defects or irregularities relating thereto have been
expressly waived or cured to the satisfaction of Purchaser. None of Purchaser,
Parent, Tyco, the Depositary, the Information Agent or any other person will be
under any duty to give notification of any defects or irregularities in tenders,
nor shall any of them incur any liability for failure to give any such
notification.

    OTHER REQUIREMENTS.  By executing the Letter of Transmittal, a tendering
shareholder irrevocably appoints designees of Purchaser as such shareholder's
proxies, in the manner set forth in the Letter of Transmittal, each with full
power of substitution, to the full extent of such shareholder's rights with
respect to the Shares tendered by such shareholder and accepted for payment by
Purchaser (and any and all other Shares or other securities or rights issued or
issuable in respect of such Shares on or after November 1, 1999), effective if,
when and to the extent that Purchaser accepts such Shares for payment pursuant
to the Offer. Upon such acceptance for payment, all prior proxies given by such
shareholder with respect to such Shares or other securities accepted for payment
will, without further action, be revoked, and no subsequent proxies may be given
by such shareholder nor any subsequent written consents executed (and, if given
or executed, will not be deemed effective). Such designees of Purchaser will,
with respect to such Shares and other securities or rights issuable in respect
thereof, be empowered to exercise all voting and other rights of such
shareholder as they, in their sole discretion, may deem proper in respect of any
annual, special or adjourned meeting of the Company's shareholders, action by
written consent in lieu of any such meeting or

                                       9
<PAGE>
otherwise. Purchaser reserves the right to require that, in order for Shares to
be deemed validly tendered, immediately upon Purchaser's acceptance for payment
of such Shares, Purchaser must be able to exercise full voting rights with
respect to such Shares.

    Purchaser's acceptance for payment of Shares tendered pursuant to any of the
procedures described above will constitute a binding agreement between the
tendering shareholder and Purchaser upon the terms and subject to the conditions
of the Offer.

    To prevent backup withholding of federal income tax on payments made to
shareholders with respect to Shares purchased pursuant to the Offer, each
shareholder must provide the Depositary with his correct taxpayer identification
number ("TIN") and certify that he is not subject to backup withholding of
federal income tax by completing the Substitute Form W-9 included in the Letter
of Transmittal. Non-United States holders must submit a completed Form W-8 to
avoid backup withholding. This form may be obtained from the Depositary. See
Instructions 10 and 11 of the Letter of Transmittal.

    3. WITHDRAWAL RIGHTS.  Tenders of Shares made pursuant to the Offer will be
irrevocable, except that Shares tendered may be withdrawn at any time prior to
the Expiration Date, and, unless theretofore accepted for payment by Purchaser
as provided herein, may also be withdrawn on or after January 1, 2000.

    For a withdrawal of Shares tendered to be effective, a written, telegraphic,
telex or facsimile transmission notice of withdrawal must be timely received by
the Depositary at one of its addresses set forth on the back cover of this Offer
to Purchase. Any notice of withdrawal must specify the name of the person who
tendered the Shares to be withdrawn, the number of Shares to be withdrawn and
the name(s) in which the certificate(s) representing such Shares are registered,
if different from that of the person who tendered such Shares. If certificates
for Shares to be withdrawn have been delivered or otherwise identified to the
Depositary, the name of the registered holder and the serial numbers shown on
the particular certificates evidencing such Shares to be withdrawn must also be
furnished to the Depositary prior to the physical release of the Shares to be
withdrawn. The signature(s) on the notice of withdrawal must be guaranteed by an
Eligible Institution (except in the case of Shares tendered by an Eligible
Institution). If Shares have been tendered pursuant to the procedures for
book-entry transfer set forth in Section 2, any notice of withdrawal must
specify the name and number of the account at DTC to be credited with such
withdrawn Shares and must otherwise comply with DTC's procedures.

    If Purchaser extends the Offer, is delayed in its acceptance for payment of
any Shares tendered, or is unable to accept for payment or pay for Shares
tendered pursuant to the Offer, for any reason whatsoever, then, without
prejudice to Purchaser's rights set forth herein, the Depositary may,
nevertheless, on behalf of Purchaser, retain tendered Shares, and such Shares
may not be withdrawn except to the extent that the tendering shareholder is
entitled to and duly exercises withdrawal rights as described in this Section
and as otherwise required by Rule 14e-1(c) under the Exchange Act. Any such
delay will be accompanied by an extension of the Offer to the extent required by
law.

    Withdrawals of tenders of Shares may not be rescinded and Shares properly
withdrawn will thereafter be deemed not validly tendered for purposes of the
Offer. However, withdrawn Shares may be retendered by again following the
procedures described in Section 2 at any time prior to the Expiration Date.

    All questions as to the form and validity (including time of receipt) of
notices of withdrawal will be determined by Purchaser, in its sole discretion,
and its determination will be final and binding on all parties. None of
Purchaser, Parent, Tyco, the Depositary, the Information Agent or any other
person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal, nor shall any of them incur any
liability for failure to give any such notification.

    4. ACCEPTANCE FOR PAYMENT AND PAYMENT OF OFFER PRICE.  Upon the terms and
subject to the conditions of the Offer (including, if the Offer is extended or
amended, the terms and conditions of any extension or amendment), Purchaser will
accept for payment and will pay for all Shares validly tendered prior to the
Expiration Date (and not properly withdrawn in accordance with Section 3 above)
as soon as practicable

                                       10
<PAGE>
after the latest to occur of (a) the expiration or termination of the waiting
period applicable to the acquisition of the Shares pursuant to the Offer under
the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR
Act"), (b) the Expiration Date, and (c) subject to compliance with
Rule 14e-1(c) under the Exchange Act, the satisfaction or waiver of the
conditions of the Offer set forth in Section 15. Any determination concerning
the satisfaction of such terms and conditions shall be within the sole
discretion of Purchaser, and such determination shall be final and binding on
all tendering shareholders. See Section 15.

    Purchaser expressly reserves the right to delay acceptance for payment of,
or payment for, Shares in order to comply in whole or in part with any
applicable law. If Purchaser desires to delay payment for Shares accepted for
payment pursuant to the Offer, and such delay would otherwise be in
contravention of Rule 14e-1(c) of the Exchange Act, Purchaser will formally
extend the Offer. See Section 15. In all cases, payment for Shares accepted for
payment pursuant to the Offer will be made only after timely receipt by the
Depositary of (i) certificates representing such Shares (or a timely
confirmation of a book-entry transfer of such Shares into the Depositary's
account at DTC, as described in Section 2), (ii) a properly completed and duly
executed Letter of Transmittal (or facsimile thereof) with any required
signature guarantees (or, in connection with a book-entry transfer, an Agent's
Message), and (iii) any other documents required by the Letter of Transmittal.

    For purposes of the Offer, Purchaser will be deemed to have accepted for
payment, and thereby purchased, tendered Shares when, as and if Purchaser gives
oral or written notice to the Depositary, as agent for the tendering
shareholders, of Purchaser's acceptance for payment of such Shares. Payment for
Shares so accepted for payment will be made by the deposit of the purchase price
therefor with the Depositary, which will act as agent for the tendering
shareholders for the purpose of receiving such payment from Purchaser and
transmitting such payment to tendering shareholders. If, for any reason
whatsoever, acceptance for payment of any Shares tendered pursuant to the Offer
is delayed, or Purchaser is unable to accept for payment Shares tendered
pursuant to the Offer, then, without prejudice to Purchaser's rights under
Section 1, the Depositary may, nevertheless, on behalf of Purchaser, retain
tendered Shares, and such Shares may not be withdrawn, except to the extent that
the tendering shareholders are entitled to withdrawal rights as described in
Section 3 and as otherwise required by Rule 14e-1(c) under the Exchange Act.
Under no circumstances will interest be paid on the purchase price by reason of
any delay in making such payments.

    If any tendered Shares are not accepted for payment and paid for,
certificates representing such Shares will be returned (or, in the case of
Shares delivered by book-entry transfer with DTC as permitted by Section 2, such
Shares will be credited to an account maintained with DTC) without expense to
the tendering shareholder as promptly as practicable following the expiration or
termination of the Offer.

    If, prior to the Expiration Date, Purchaser increases the consideration to
be paid for Shares pursuant to the Offer, Purchaser will pay such increased
consideration for all Shares accepted for payment pursuant to the Offer, whether
or not such Shares have been tendered or accepted for payment prior to such
increase in the consideration.

    Purchaser reserves the right to transfer or assign in whole or in part to
one or more affiliates of Purchaser, Parent or Tyco the right to purchase all or
any portion of the Shares tendered pursuant to the Offer, but any such transfer
or assignment will not relieve Purchaser of its obligations under the Offer and
will in no way prejudice the rights of tendering shareholders to receive payment
for Shares validly tendered and accepted for payment pursuant to the Offer.

    5. CERTAIN FEDERAL INCOME TAX CONSEQUENCES.  The receipt of cash for Shares
pursuant to the Offer (or in the Merger) will be a taxable transaction for
United States federal income tax purposes (and may also be a taxable transaction
under applicable state, local or other tax laws). In general, a shareholder will
recognize gain or loss for such purposes equal to the difference between such
shareholder's adjusted tax basis for the Shares such shareholder sells in such
transaction and the amount of cash received therefor.

                                       11
<PAGE>
Gain or loss must be determined separately for each block of Shares (i.e.,
Shares acquired at the same cost in a single transaction) sold pursuant to the
Offer or converted to cash in the Merger. Such gain or loss will be capital gain
or loss if the Shares are a capital asset in the hands of the shareholder and
will be long term capital gain or loss if the Shares were held for more than one
year on the date of sale (in the case of the Offer) or the effective time of the
Merger (in the case of the Merger). The receipt of cash for Shares pursuant to
the exercise of dissenters' rights, if any, will generally be taxed in the same
manner as described above.

    Payments in connection with the Offer or the Merger may be subject to
"backup withholding" at a rate of 31%. Backup withholding generally applies if
the shareholder (a) fails to furnish such shareholder's social security number
or TIN, (b) furnishes an incorrect TIN, or (c) under certain circumstances,
fails to provide a certified statement, signed under penalties of perjury, that
the TIN provided is such shareholder's correct number and that such shareholder
is not subject to backup withholding. Backup withholding is not an additional
tax but merely an advance payment, which may be refunded to the extent it
results in an overpayment of tax. Certain persons generally are entitled to
exemption from backup withholding, including corporations, non-United States
persons and financial institutions. Certain penalties apply for failure to
furnish correct information and for failure to include reportable payments in
income. Each shareholder should consult with his own tax advisor as to such
shareholder's qualification for exemption from backup withholding and the
procedure for obtaining such exemption. Tendering shareholders may be able to
prevent backup withholding by completing the Substitute Form W-9 included in the
Letter of Transmittal.

    The foregoing discussion may not be applicable to a shareholder who acquired
Shares pursuant to the exercise of employee stock options or otherwise as
compensation, or to a shareholder who is not a United States person for United
States federal income tax purposes (including a shareholder who is not a citizen
or resident of the United States) or who is otherwise subject to special tax
treatment under the Internal Revenue Code. In addition, the foregoing discussion
does not address the tax treatment of holders of options or warrants to acquire
Shares or of securities convertible into Shares.

    The federal income tax discussion set forth above is included for general
information only and is based upon present law. Shareholders are urged to
consult their tax advisors with respect to the specific tax consequences of the
Offer and the Merger to them, including the application and effect of the
alternative minimum tax, and state, local or non-United States income and other
tax laws.

    On October 26, 1999, the last trading day prior to the public announcement
of the terms of the Offer and the Merger, the closing per Share sales price on
the Nasdaq National Market System was $4.34. On October 29, 1999, the last
trading day prior to commencement of the Offer, the closing per Share sales
price on the Nasdaq National Market System was $5.34. Shareholders are urged to
obtain a current market quotation for the Shares.

    7. EFFECTS OF THE OFFER ON THE MARKET FOR SHARES; STOCK QUOTATIONS;
REGISTRATION UNDER THE EXCHANGE ACT. The purchase of Shares pursuant to the
Offer will reduce the number of holders of Shares and the number of Shares that
might otherwise trade publicly. Consequently, depending upon the number of
Shares purchased and the number of remaining holders of Shares, the purchase of
Shares pursuant to the Offer may adversely affect the liquidity and market value
of the remaining Shares held by the public. Purchaser cannot predict whether the
reduction in the number of Shares that might otherwise trade publicly would have
an adverse or beneficial effect on the market price for, or marketability of,
the Shares or whether it would cause future market prices to be greater or less
than the Offer price.

    The Shares are currently listed and traded on the Nasdaq National Market
System, which constitutes the principal trading market for the Shares. Depending
upon the aggregate market value and the number of Shares not purchased pursuant
to the Offer, the Shares may no longer meet the quantitative maintenance
criteria for continued inclusion on the Nasdaq National Market System and may
cease to be authorized for quotation on such market. Pursuant to the maintenance
criteria, issuers on the Nasdaq National Market System are required to have
(i) (A) at least 750,000 publicly held shares, (B) at least 400 holders of round
lots, (C) a market value of publicly held shares of at least $5 million, (D) a
minimum bid price per share of $1, and (E) net tangible assets of at least
$4 million or (ii) (A) at least 1.1 million publicly held shares, (B) at least
400 holders of round lots, (C) a market value of publicly held shares of at
least $15 million, (D) a market capitalization of at least $50 million or total
assets and total revenue of at least $50 million (each for the most recently
completed fiscal year or two of the last three most recently completed fiscal
years), (E) a minimum bid price per share of $5, and (F) at least four
registered and active market makers for the Shares. Shares held directly or
indirectly by directors, officers or beneficial owners of more than 10% of the
Shares outstanding are not considered as being publicly held for this purpose.

    If, as a result of the purchase of Shares pursuant to the Offer or
otherwise, the Shares no longer meet the requirements for continued inclusion in
the Nasdaq National Market System or in any other tier of The

                                       13
<PAGE>
Nasdaq Stock Market, and the Shares are no longer included in The Nasdaq
National Market or in any other tier of The Nasdaq Stock Market, the market for
Shares could be adversely affected.

    In the event that the Shares no longer meet the requirements for continued
inclusion in any tier of The Nasdaq Stock Market, it is possible that Shares
would continue to trade in the over-the-counter market and that price quotations
would be reported on the Nasdaq bulletin board or by other sources. The extent
of the public market for the Shares and the availability of such quotations
would, however, depend upon the number of holders of Shares remaining at such
time, the interest in maintaining a market in Shares on the part of securities
firms, the possible termination of registration of the Shares under the Exchange
Act, as described below, and other factors.

    The Shares are currently registered under the Exchange Act. Such
registration may be terminated upon application of the Company to the Commission
if such Shares are not listed on a national securities exchange and there are
fewer than 300 holders of record of the Shares. The termination of the
registration of the Shares under the Exchange Act would substantially reduce the
information required to be furnished by the Company to its shareholders and to
the Commission, and would make certain of the provisions of the Exchange Act,
such as the short-swing profit recovery provisions of Section 16(b) and the
requirement of furnishing a proxy statement in connection with shareholders'
meetings and the related requirement of an annual report to shareholders, and
the requirements of Rule 13e-3 with respect to going private transactions, no
longer applicable with respect to the Shares or to the Company. Furthermore, if
registration of the Shares under the Exchange Act were terminated, the ability
of "affiliates" of the Company and persons holding "restricted securities" of
the Company to dispose of such securities pursuant to Rule 144 promulgated under
the Securities Act of 1933, as amended, may be impaired or, with respect to
certain persons, eliminated. If the Shares were no longer registered under the
Exchange Act, they would not be eligible for listing on any tier of The Nasdaq
Stock Market or for quotation on the Nasdaq bulletin board. According to the
Company, as of October 29, 1999, there were 1,422 holders of record of the
Shares.

    The Shares are currently "margin securities" under the regulations of the
Board of Governors of the Federal Reserve System (the "Federal Reserve Board"),
which has the effect, among other things, of allowing brokers to extend credit
on such Shares as collateral. Depending on factors similar to those described
above regarding listing and market quotations, it is possible the Shares would
no longer constitute "margin securities" for purposes of the Federal Reserve
Board's margin regulations and therefore could no longer be used as collateral
for loans made by brokers. If registration of the Shares under the Exchange Act
were terminated, the Shares would no longer be "margin securities."

forth herein, the information concerning the Company contained in this Offer to
Purchase, including financial information, has been furnished by the Company or

understanding or relationship with any other person with respect to any
securities of the Company, including, but not limited to, any contract,
arrangement, understanding or relationship concerning the transfer or the voting
of any securities of the Company, joint ventures, loan or option arrangements,

consolidation, acquisition, tender offer or other acquisition of securities,
election of directors or a sale or other transfer of a material amount of assets
or (c) has had any other transaction with the Company or any of its executive
officers, directors or affiliates that would require disclosure under the rules
and regulations of the Commission applicable to the Offer. Other than the rights

                                       18
<PAGE>
    10. SOURCE AND AMOUNT OF FUNDS.  The total amount of funds required by Tyco,
Parent and Purchaser to purchase all Shares pursuant to the Offer and the
Merger, (including amounts payable upon exercise to optionholders) and to pay
related fees and expenses, is estimated to be approximately $80 million. This
does not include approximately $93 million of indebtedness that the Surviving
Corporation will either repay or assume upon consummation of the Offer and the
Merger.

    Purchaser will obtain all such funds from Tyco, Parent or their affiliates.
Tyco has sufficient financial resources to satisfy its, Parent's, and
Purchaser's obligations under the Offer and the Merger Agreement, and Tyco has
fully and unconditionally guaranteed the Offer. This Offer is not conditioned
upon any financing arrangements.

    11. CONTACTS WITH THE COMPANY; BACKGROUND OF THE OFFER.  Certain information
in this section on the background of the Offer regarding the deliberations of
the Company's Board and the actions of the Company's management and financial
advisors is based upon information furnished by the Company to Purchaser. In
this section, references to Tyco are to Tyco's United States subsidiaries and
affiliates including Tyco (US) and Tyco Printed Circuit Group. Tyco, the Bermuda
company, is referred to in this section as Tyco International Ltd.

    In April 1999, the Company began to explore strategic alternatives,
including acquisition possibilities. At that time, the Company retained Adams,
Harkness & Hill, Inc. and McDonald Investments Inc. to assist it in this
broad-ranging exploration. McDonald and KeyBank, the Company's principal
creditor, are both wholly owned subsidiaries of KeyCorp. Beginning in late
April 1999, Adams Harkness and McDonald contacted not less than 24 companies to
gauge their interest in potential strategic business relationships and business
combinations with the Company. As a result of these contacts, the Company
entered into discussions with four companies concerning a possible transaction.

    On April 27, 1999, McDonald contacted a private equity investment firm
("Equity Investment Company A") to discuss a possible transaction. On April 28,
1999, Adams Harkness contacted another private equity investment firm ("Equity
Investment Company B") and Tyco for the same purpose.

    On April 29, 1999, Equity Investment Company A contacted McDonald indicating
interest in pursuing a possible transaction. On the same day, Steve Gardner,
President of Tyco Printed Circuit Group, contacted Adam Harkness, indicated that
Tyco was interested in pursuing a transaction and requested Adam Harkness to
contact Brian Roussell, Vice President of Finance and Administration of Tyco
Printed Circuit Group. Adam Harkness contacted Mr. Roussell on that same day
regarding a possible transaction.

    From May 3, 1999 through May 9, 1999, Tyco Printed Circuit Group and the
Company negotiated a confidentiality agreement, which was signed on May 10,
1999, at which time each party commenced due diligence on the other. During the
week of May 3, 1999, Equity Investment Company A and the Company signed
confidentiality agreements and commenced due diligence on each other.

    On May 5, 1999, the Company and Equity Investment Company B began
negotiating a confidentiality agreement, which was signed on May 13, 1999.

    On May 12, 1999, Equity Investment Company A, the Company and their
respective advisers met at the offices of the Company's legal advisers in
Portland, Oregon to discuss due diligence matters. Additional due diligence
discussions were held on May 14, 1999 and during the weeks of May 16, 1999 and
May 24, 1999.

    On May 17, 1999, Equity Investment Company B scheduled a meeting with
Mr. Bergeron to discuss a possible transaction.

    On May 19 and 20, 1999, Tyco, the Company and their respective advisers held
meetings at the Company's headquarters offices in Tualatin, Oregon and at the
offices of the Company's legal advisers in Portland, Oregon to continue
discussing a possible business combination. The Company's and Tyco's

                                       19
<PAGE>
respective management and advisers participated in these meetings. The parties
held preliminary discussions about the non-financial aspects of a potential
acquisition of the Company by Tyco, including organization, facilities, products
and customers.

    On May 20, 1999, representatives of Equity Investment Company B met with
Mr. Bergeron in Dallas, Oregon and conducted due diligence.

    On May 24, 1999, Equity Investment Company B contacted Adams Harkness and
asked for additional due diligence information. On June 1, 1999, Equity
Investment Company B informed Adams Harkness that, although Equity Investment
Company B was interested in pursuing a possible business combination, for
financing and timing reasons it wished to delay discussions for at least three
months.

    On June 3, 1999, Tyco presented the Company with a non-binding indication of
interest letter, suggesting a cash price of $7.25 to $8.00 per share for the
acquisition of all shares of the Company's common stock. From June 4, 1999
through June 21, 1999, the parties exchanged additional information and
internally reviewed the potential benefits of a transaction.

    Also on June 3, 1999, Equity Investment Company A indicated it was
considering a recapitalization transaction that would value the Company's common
stock at approximately $6.00 per share, but that Equity Investment Company A
required additional due diligence before it would be in the position to finalize
an offer. Equity Investment Company A conducted further due diligence on
June 4, 1999 and during the week of June 6, 1999.

    On June 14 and 15, and also from June 21 to June 24, 1999, representatives
of Tyco conducted due diligence at the offices of the Company's legal advisers
in Portland, Oregon.

    On June 16, 1999, Equity Investment Company A notified McDonald that Equity
Investment Company A was prepared to enter into a recapitalization transaction
with the Company that would value the Company's common stock at $4.00 per share.
On June 20, 1999, McDonald informed Equity Investment Company A that the Company
had decided to postpone any decision on the proposal for at least two months.

    On June 22, 1999, the president of a printed circuit board manufacturer (the
"PCB Company") contacted Mr. Bergeron about a possible business combination.

    On June 24, 1999, representatives of the PCB Company and the Company met to
discuss a possible business combination. The PCB Company and the Company entered
into confidentiality agreements and completed due diligence on June 28, 1999.

    On June 29, 1999, Richard D. Malloy, Director of Mergers and Acquisitions of
Tyco (US), orally informed the Company that the proposal in its June 3, 1999
letter was no longer feasible due to valuation issues and concern about the
status of the Company's credit arrangements. Mr. Malloy indicated Tyco was still
interested in pursuing a transaction, and suggested postponing further
discussion until the Company's circumstances were clarified.

    Also on June 29, 1999, the PCB Company indicated it would submit a business
combination proposal on July 2, 1999, but on July 1, 1999, the PCB Company
informed the Company that no proposal would be forthcoming on July 2, 1999. The
PCB Company requested more time to consider alternatives and to conduct
additional due diligence. On July 21, 1999, the PCB Company informed McDonald
that the PCB Company might be interested only in purchasing one or two of the
Company's manufacturing facilities, but the PCB Company never submitted any
transaction proposal for the Company's consideration.

    On August 5, 1999, the Company announced its financial results for the
fourth quarter and fiscal year ended June 30, 1999. For the fourth quarter, the
Company reported a modest increase in revenue from the prior year and a
restructuring that resulted in a pretax charge of $21.4 million. The Company
also reported that at June 30, 1999 it was not in compliance with all the
covenants of its major credit agreements, including its revolving credit
agreement with KeyBank. The Company reported that its business and

                                       20
<PAGE>
financial condition could be materially and adversely effected if it were unable
to reach agreements with its creditors.

    On August 31, 1999, Mr. Bergeron asked Adams Harkness to contact Tyco to
recommence transaction discussions. Adams Harkness left a message with Tyco on
September 1, 1999, and on September 2, 1999 Mr. Malloy informed Adams Harkness
that Tyco would consider recommencing discussions.

    On September 7, 1999, Mr. Malloy called Mr. T. L. Stebbins, a director of
the Company and a managing director at Adam Harkness, and indicated Tyco was
interested in recommencing discussions with the Company, with the understanding
that Tyco was prepared to offer no more than $5.50 per share for the acquisition
of all shares of the Company common stock until the Company's September 1999
financial statements were available. Upon receipt of this information,
Mr. Bergeron instructed Adams Harkness to cease communications with Tyco.

    On September 10, 1999, the Company's commercial lenders requested that the
Company renegotiate its credit arrangements. Following this request, Robert
Praegitzer, Chairman of the Board and Chief Executive Officer of the Company,
and Mr. Bergeron convened a conference call among themselves, Adams Harkness and
McDonald during which Mr. Praegitzer and Mr. Bergeron requested that Adams
Harkness and McDonald contact a number of the original companies who Adams
Harkness and McDonald thought might be interested in purchasing the Company at a
lower price. Mr. Praegitzer and Mr. Bergeron also asked Adams Harkness to
contact Tyco to inform Tyco that the Company was interested in recommencing
transaction discussions at a price per share to be determined after Tyco had
completed its due diligence.

    On September 13, 1999, Mr. Stebbins discussed the Company's position with
Mr. Malloy, who requested updated due diligence materials and financial
statements.

    On September 15, 1999, Adams Harkness contacted Investment Company Company B
to gauge its interest in recommencing discussions concerning a possible
transaction.

    On September 16, 1999, the Company's Board of Directors met to discuss the
status of negotiations with Tyco.

    On September 20, 1999, Mr. Malloy indicated Tyco's interest in proceeding
with a transaction to Adams Harkness. Mr. Malloy and Mr. Bergeron arranged
several due diligence meetings at the Company's headquarters offices in
Tualatin, Oregon over the next two weeks.

    On September 21, 1999, the management of the Company and its advisers met at
the Company's headquarters offices in Tualatin, Oregon with representatives of
Tyco to discuss a possible business combination. On the same day, Equity
Investment Company B indicated to Adams Harkness that Equity Investment Company
B was interested in pursuing discussions, but that Equity Investment Company B
was now interested only in purchasing certain Company manufacturing facilities
rather than the entire Company.

    On September 23, 1999, the Company Board met to approve the delayed filing
with the Commission of its Annual Report on Form 10-K for the year ended
June 30, 1999 and to explore strategic alternatives with McDonald and Adams
Harkness.

    On September 29, 1999, Adams Harkness contacted Tyco to discuss the status
of Tyco's expected offer.

    In late September 1999, McDonald contacted Equity Investment Company A to
determine Equity Investment Company A's interest in recommencing discussions
concerning a possible transaction with the Company. On October 7, 1999, Equity
Investment Company A, Praegitzer and their respective advisers met at the
Company's headquarters offices in Tualatin, Oregon to discuss a possible
transaction. At that meeting Equity Investment Company A presented the Company
with a letter of interest for the purchase solely of the Company's Dallas and
Fremont manufacturing facilities, conditioned on satisfactory financing
arrangements and additional due diligence.

                                       21
<PAGE>
    On October 12, 1999, the Company executed the Deferral Agreement with
substantially all of its lenders and lessors, thereby eliminating the existing
covenant defaults and the prospect of immediate acceleration of the amounts due
to those creditors.

    Also on October 12, 1999, Equity Investment Company B informed Adams
Harkness that Equity Investment Company B was no longer interested in pursuing
any acquisition discussions.

    On October 13, 1999, the Company filed with the Commission its Annual Report
on Form 10-K for the fiscal year ended June 30, 1999, which had been due to be
filed September 28, 1999.

    Also on October 13, 1999, Tyco delivered an acquisition proposal to the
Company. Under the terms of the proposal, Tyco would acquire the Company by
means of a cash tender offer, at a price of $5.50 per share of the Company
common stock. Representatives of Equity Investment Company A completed
additional due diligence on the same day.

    On October 15, 1999, the the Company Board met with Adams Harkness at the
Company's headquarters offices in Tualatin, Oregon to review Tyco's proposal and
discuss tender offer procedures.

    On October 15, 1999, Tyco International Ltd.'s Board of Directors approved
the acquisition of the Company at a price of $5.50 per share of the Company's
common stock.

    On October 16, McDonald contacted Equity Investment Company A to inform
Equity Investment Company A that the Company preferred a transaction pursuant to
which all of the common stock of the Company would be acquired, rather than an
asset purchase of only two of the Company's facilities. McDonald also informed
Equity Investment Company A that the Company was seeking a stock transaction
that valued its common stock at $6.00 per share or greater. On October 17, 1999,
Equity Investment Company A informed McDonald that Equity Investment Company A
was not interested in purchasing all of the stock of the Company, but was only
interested in purchasing the two manufacturing facilities.

    On October 18, 1999, Mr. Stebbins informed Tyco that the Company was
entertaining other potential proposals for certain Company assets. Adams
Harkness requested that Tyco propose a transaction either at a higher price per
share or with a different structure. On October 20, 1999, Irving Gutin,
Tyco (US)'s Senior Vice President, and Mr. Malloy declined to modify Tyco's
proposal.

    On October 19, 1999, Tyco, the Company and Adams Harkness convened several
conference calls to discuss Tyco's proposal and the transaction schedule.

    On October 20, 1999, Mr. Bergeron verbally accepted Tyco's non-binding
written offer on the Company's behalf and requested Mr. Malloy supply a draft
merger agreement, which the Company received from Tyco's legal advisers on
October 22, 1999.

    From October 22 through October 26, 1999, Tyco, the Company and their
respective advisers negotiated the terms and provisions of the Merger Agreement
and ancillary documents.

    The Company's Board of Directors met on October 25, 1999. At the meeting

    - the Company's legal advisers and management updated the Company's Board on
      the status of negotiations with Tyco and informed the Board that all
      substantive issues had been resolved,

    - the Company's legal advisers made a presentation to the Company's Board
      regarding the fiduciary duties of the Company's Board,

    - the Company's legal advisers reviewed with the Company's Board the terms
      of the proposed merger agreement with Tyco and the regulatory filings and
      approvals that would be required in connection with the proposed
      transaction,

    - Adams Harkness made a financial presentation to the Company's Board, and

    - Adams Harkness rendered its opinion to the effect that, as of that date,
      the Per Share Amount was fair to the Company's shareholders from a
      financial point of view.

                                       22
<PAGE>
    Afterwards, the Company's Board by a unanimous vote (with Mr. Stebbins
abstaining because he is a managing director of Adams Harkness, which is
entitled to a fee payable in part upon the completion of a transaction such as
that presented by Tyco) determined the Merger was fair to, and in the best
interests of, the Company and its shareholders and

    - unanimously approved (again with Mr. Stebbins abstaining) the terms of the
      Merger Agreement and the transactions contemplated by the agreement, and

    - authorized the execution of the Merger Agreement and recommended that the
      Company's shareholders tender all their shares in the Tyco Offer.

    On October 25, 1999 the closing price of the Company's common stock was
$4.75 per share.

    On October 26, 1999 all documentation, including the disclosure schedules of
the Company, were finalized to the satisfaction of the designated officers, and
all conditions with respect to the execution of the Merger Agreement were
satisfied. Late in the morning of that day, the Company Board met to receive an
update from Mr. Bergeron as to the status of the transaction. That afternoon

    - Tyco and the Company executed and delivered the Merger Agreement,

    - the majority shareholder of the Company executed and delivered a
      shareholder agreement agreeing to tender the shareholder's shares in the
      Tyco Offer, and

    - Tyco and the Company publicly announced the signing of the Merger
      Agreement.

    12. PURPOSE OF THE OFFER; SHORT FORM MERGER; PLANS FOR THE COMPANY;
        DISSENTERS' RIGHTS; GOING PRIVATE TRANSACTIONS.

    PURPOSE OF THE OFFER.  The purpose of the Offer is for Purchaser to acquire
control of, and a majority equity interest in, the Company. The purpose of the
Merger is to acquire the remaining equity interest. The acquisition of the
entire common equity interest in the Company has been structured as a cash
tender offer followed by a cash merger in order to provide a prompt and orderly
transfer of ownership of the common equity of the Company from the public
shareholders to Parent and to provide public shareholders with cash for all of
their Shares. Accordingly, upon consummation of the transactions contemplated by
the Merger Agreement, Parent will own the entire equity interest in the Company.

    Under the OBCA and the Company's Articles of Incorporation, the approval of
the Board of Directors of the Company and the affirmative vote of a majority of
the holders of outstanding Shares, voting as a single class, are required to
approve and adopt the Merger Agreement and the Merger. The Board of Directors of
the Company has approved the Offer, the Merger and the Merger Agreement and the
transactions contemplated thereby, and, unless the Merger is consummated
pursuant to the short-form merger provisions under the OBCA described below, the
only remaining required corporate action of the Company is the approval and
adoption of the Merger Agreement and the Merger by the affirmative vote of the
holders of a majority of the outstanding Shares. If the Minimum Condition is
satisfied, Purchaser will have sufficient voting power to cause the approval and
adoption of the Merger Agreement and the Merger without the affirmative vote of
any other shareholder.

    The Merger Agreement provides that, if approval of the Merger by the
shareholders of the Company is required by law, the Company will, as soon as
possible following payment for Shares in the Offer, duly call and hold a meeting
of shareholders for the purpose of obtaining shareholder approval of the Merger,
and the Company, through its Board of Directors, will recommend to shareholders
that such approval be given.

    SHORT FORM MERGER.  Under the OBCA, if Purchaser acquires at least 90% of
the outstanding Shares, Purchaser will be able to approve the Merger without a
vote of the Company's other shareholders. The Merger Agreement provides that if
Purchaser, or any other direct or indirect subsidiary of Tyco or Parent,
acquires at least 90% of the outstanding Shares, Parent, Purchaser and the
Company will take all necessary

                                       23
<PAGE>
and appropriate action to cause the Merger to become effective as soon as
practicable after the expiration of the Offer without a meeting of shareholders
of the Company, in accordance with Section 60.491 of the OBCA. If Purchaser
acquires at least 90% of the Shares in the Offer, it will be able to effect the
Merger under Section 60.491 of the OBCA. In the event that all of the conditions
to Purchaser's obligation to purchase Shares in the Offer are satisfied or
waived and the number of Shares tendered is less than 90% of the outstanding
Shares, Purchaser may, subject to the limitations set forth in the Merger
Agreement, extend the Offer for an aggregate period of not more than 10 business
days (for all such extensions) without the consent of the Company. See
Section 1. If Purchaser does not acquire at least 90% of the outstanding Shares,
a significantly longer period of time may be required to effect the Merger,
because a vote of the Company's shareholders would be required under the OBCA.

    PLANS FOR THE COMPANY.  Except as otherwise set forth in this Offer to
Purchase, it is expected that, initially following the Merger, the business and
operations of the Company will be continued by the Surviving Corporation
substantially as they are currently being conducted, but within Tyco's Printed
Circuit Board Group. The directors of Purchaser will be the initial directors of
the Surviving Corporation, and the officers of the Company will be the initial
officers of the Surviving Corporation. Upon completion of the Offer, Tyco
intends to conduct a detailed review of the Company and its assets, corporate
structure, capitalization, operations, policies, management and personnel. After
such review, Tyco will determine what actions or changes, if any, would be
desirable in light of the circumstances which then exist, and reserves the right
to effect such actions or changes.

    Except as described in this Offer to Purchase, none of Tyco, Parent or
Purchaser have any present plans or proposals that would relate to or result in
(i) any extraordinary corporate transaction, such as a merger, reorganization or
liquidation, involving the Company or any of its subsidiaries, (ii) a sale or
transfer of a material amount of assets of the Company or any of its
subsidiaries, (iii) any change in the Company's Board of Directors or
management, (iv) any material change in the Company's capitalization or dividend
policy, (v) any other material change in the Company's corporate structure or
business, (vi) a class of securities of the Company being delisted from a
national securities exchange or ceasing to be authorized to be quoted in an
inter-dealer quotation system of a registered national securities association,
or (vii) a class of equity securities of the Company becoming eligible for
termination of registration pursuant to Section 12(g) of the Exchange Act.

    DISSENTERS' RIGHTS.  No dissenters' rights are available in connection with
the Offer. Under Oregon law dissenters' rights are not available in a merger to
holders of any shares of stock which, like the Company's common stock, are
listed for quotation on the Nasdaq National Market System. Accordingly, if the
Company's common stock remains listed on the Nasdaq National Market System
following completion of the Offer, the Company's shareholders will have no
dissenters' rights in connection with the Merger. If, however, the Company's
common stock is not quoted on the Nasdaq National Market System on the record
date for determining shareholders eligible to vote on the Merger, shareholders
of the Company may have certain rights under the OBCA to dissent, and demand
appraisal of, and to obtain payment for the fair value of their Shares. Such
rights, if the statutory procedures were complied with, could lead to a judicial
determination of the fair value of the Shares (excluding any element of value
arising from the accomplishment or expectation of the Merger) to be required to
be paid in cash to such dissenting holders for their Shares. In addition, such
dissenting shareholders would be entitled to receive payment of a fair rate of
interest from the date of consummation of the Merger on the amount determined to
be the fair value of their Shares. In determining the fair value of the Shares,
an Oregon court would be required to take into account all relevant factors.
Accordingly, such determination could be based upon considerations other than,
or in addition to, the market value of the Shares. Therefore, the value so
determined in any appraisal proceeding could be different from the price being
paid in the Offer.

    GOING PRIVATE TRANSACTIONS.  The Merger would have to comply with any
applicable Federal law operative at the time. The Commission has adopted
Rule 13e-3 under the Exchange Act which is applicable to certain "going private"
transactions and which may under certain circumstances be applicable

                                       24
<PAGE>
to the Merger or another business combination following the purchase of Shares
pursuant to the Offer in which Purchaser, Parent or Tyco seeks to acquire the
remaining Shares not held by it. Purchaser believes, however, that Rule 13e-3
will not be applicable to the Merger. If applicable, Rule 13e-3 requires, among
other things, that certain financial information concerning the Company and
certain information relating to the fairness of such transaction and the
consideration offered to minority shareholders in such transaction be filed with
the Commission and disclosed to shareholders prior to the consummation of such
transaction.

    13. THE MERGER AGREEMENT; SHAREHOLDER'S AGREEMENT.

THE MERGER AGREEMENT

    The following summary of certain provisions of the Merger Agreement, a copy
of which is filed as an exhibit to the Schedule 14D-1 referred to in
Section 18, is qualified in its entirety by reference to the text of the Merger
Agreement. Capitalized terms used in the following summary and not otherwise
defined in this Offer to Purchase shall have the meanings set forth in the
Merger Agreement.

    THE MERGER.  The Merger Agreement provides that, following the consummation
of the Offer and subject to the terms and conditions thereof, at the effective
time of the Merger (the "Effective Time") Purchaser shall be merged with and
into the Company and, as a result of the Merger, the separate corporate
existence of Purchaser shall cease, and the Company shall continue as the
Surviving Corporation and a direct subsidiary of Parent.

    The respective obligations of Parent and Purchaser, on the one hand, and the
Company, on the other hand, to effect the Merger are subject to the satisfaction
or waiver at or prior to the Effective Time of each of the following conditions:
(i) Parent or Purchaser or their affiliates shall have consummated the Offer,
unless such failure to purchase is a result of a breach of Purchaser's
obligations to accept for payment or pay for Shares pursuant to the Offer in
violation of the terms of the Offer or of the Merger Agreement, (ii) the Merger
shall have been approved by the requisite vote of the shareholders, if required
by applicable law, in order to consummate the Merger, (iii) no order, statute,
rule, regulation, executive order, stay, decree, judgment or injunction shall
have been enacted, entered, promulgated or enforced by any court or other
Governmental Authority which prohibits or prevents the consummation of the
Merger which has not been vacated, dismissed or withdrawn prior to the Effective
Time, and (iv) all consents of any Governmental Authority required for the
consummation of the Merger and the transactions contemplated by the Agreement
shall have been obtained, other than where the failure to obtain such consents
is not reasonably likely to have a material adverse effect on the business,
assets, condition (financial or other), liabilities or results of operations of
the Surviving Corporation and its subsidiaries taken as a whole.

    At the Effective Time of the Merger, (i) each issued and outstanding Share
(other than Shares that are held by shareholders properly exercising dissenters'
rights under the OBCA and Shares to be cancelled pursuant to clause (ii) below)
will be canceled and extinguished and be converted into the right to receive the
Per Share Amount in cash payable to the holder thereof, without interest, upon
surrender of the certificate representing such Share. From and after the
Effective Time, the holders of certificates evidencing ownership of Shares
outstanding immediately prior to the Effective Time shall cease to have any
rights with respect to such Shares except as otherwise provided for in the
Merger Agreement or by applicable Law, (ii) each Share owned by Tyco, Parent,
Purchaser or any direct or indirect wholly owned subsidiary of Tyco immediately
before the Effective Time shall be cancelled and extinguished, and no payment or
other consideration shall be made with respect thereto and (iii) the shares of
Purchaser common stock outstanding immediately prior to the Merger will be
converted into 1,000 shares of the common stock of the Surviving Corporation,
which shares will constitute all of the issued and outstanding capital stock of
the Surviving Corporation and shall be owned by Parent.

    THE COMPANY'S BOARD OF DIRECTORS.  The Merger Agreement provides that
promptly upon the purchase by Purchaser of Shares pursuant to the Offer (and
provided that the Minimum Condition has

                                       25
<PAGE>
been satisfied), Parent shall be entitled to designate such number of directors,
rounded up to the next whole number, on the Board of Directors of the Company as
will give Parent, subject to compliance with Section 14(f) of the Exchange Act,
representation on the Board of Directors of the Company equal to at least that
number of directors which equals the product of the total number of directors on
the Board of Directors of the Company (giving effect to the directors appointed
or elected pursuant to this sentence and including current directors serving as
officers of the Company) multiplied by the percentage that the aggregate number
of Shares beneficially owned by Parent or any affiliate of Parent (including
such Shares as are accepted for payment pursuant to the Offer, but excluding
Shares held by the Company) bears to the number of Shares outstanding. At such
time, if requested by Parent, the Company will also cause each committee of the
Board of Directors of the Company to include persons designated by Parent
constituting the same percentage of each such committee as Parent's designees
are of the Board of Directors of the Company. The Company shall, upon request by
Parent, promptly increase the size of the Board of Directors of the Company or
exercise reasonable best efforts to secure the resignations of such number of
directors as is necessary to enable Parent's designees to be elected to the
Board of Directors of the Company in accordance with terms of this section and
to cause Parent's designees so to be elected; provided, however, that, in the
event that Parent's designees are appointed to the Board of Directors of the
Company, until the Effective Time the Board of Directors of the Company shall
have at least two directors who are directors on the date of the Agreement, one
of whom will be Robert Praegitzer and one of whom will be a director who is
neither an officer of the Company nor a designee, shareholder, affiliate or
associate (within the meaning of the federal securities laws) of Tyco (such
directors, the "Independent Directors"). Notwithstanding anything in the Merger
Agreement to the contrary, subsequent to the designation of the directors by
Parent and prior to the Effective Time, the unanimous vote of the Independent
Directors shall be required to (i) amend or terminate the Merger Agreement on
behalf of the Company, (ii) exercise or waive any of the Company's rights or
remedies thereunder, (iii) extend the time for performance of Parent's
obligations thereunder, (iv) take any other action by the Company in connection
with the Merger Agreement required to be taken by the Board of Directors of the
Company or (v) amend the Company's Articles of Incorporation or the Company's
Bylaws, each as in effect on the date of the Merger Agreement.

    SHAREHOLDERS' MEETING.  Pursuant to the Merger Agreement, the Company will,
if required by applicable law in order to consummate the Merger, duly call, give
notice of, convene and hold a special meeting of its shareholders as promptly as
practicable following the consummation of the Offer for the purpose of voting
upon the Merger. The Merger Agreement provides that the Company will, if
required by applicable law in order to consummate the Merger, prepare and file
with the Commission and, when cleared by the Commission, will mail to
shareholders a proxy statement in connection with a meeting of the Company's
shareholders to vote upon the Company Proposals, or an information statement, as
appropriate, satisfying all requirements of the Securities Exchange Act.

    If Purchaser acquires at least a majority of the Shares, it will have
sufficient voting power to approve the Merger, even if no other shareholder
votes in favor of the Merger.

    The Merger Agreement provides that in the event that Parent or Purchaser
acquires at least 90% of each class of Shares, Parent, Purchaser and the Company
will take all necessary and appropriate action to cause the Merger to become
effective as soon as practicable after the expiration of the Offer, without a
meeting of shareholders of the Company, in accordance with Section 60.491 of the
OBCA.

    OPTIONS, WARRANTS, CONVERTIBLE SECURITIES AND OTHER RIGHTS.  The Merger
Agreement provides that each of the Company and Parent shall take all reasonable
actions necessary to provide that all then outstanding options to purchase
Shares, whether or not then exercisable or vested (each, a "Company Option"),
shall constitute the right to receive an amount in cash equal to the positive
difference, if any, between the Per Share Amount and the exercise price of the
Company Option multiplied by the number of Shares for which the Company Option
was exercisable immediately prior to the Effective Time, subject to reduction
only for any applicable withholding taxes. The Company shall provide a period of
at least 30 days prior to

                                       26
<PAGE>
the Effective Time during which Company Options may be exercised to the extent
exercisable at the Effective Time and, upon the expiration of such period, all
unexercised Company Options shall immediately terminate. The Company may, in its
sole discretion, permit holders of Company Options that are not exercisable
before the Effective Time to exchange such options for cash as described above.
In lieu of exercising Company Options as described above, the holders shall be
given the right, and the Company shall encourage the holders of Company Options
to exercise such right, to exchange such options for cash as described above. In
no event will any Company Options be exercisable after the Effective Time,
except to receive cash.

    Each of the warrants of the Company, dated November 17, 1995, to purchase
Shares at a price of $12.00 per share, subject to adjustment (the "Company
Warrants"), shall be exercisable, from and after the Effective Time, for an
amount of cash equal to the Per Share Amount multiplied by the number of Shares
for which such warrant was exercisable immediately prior to the Effective Time.
Except as aforesaid, the exercise of any Company Warrant shall remain subject to
all terms and conditions provided in the applicable Company Warrant and/or
Warrant Agreement. Each of the Company and Parent shall take all action
necessary to provide that, upon consummation of the Merger, all Company Warrants
outstanding immediately prior to the Effective Time shall be exercisable for a
cash amount as aforesaid.

    Under the Deferral Agreement, the Company's lenders and equipment lessors
have the right to convert a certain portion of the amounts owed to them under
the Deferral Agreement into shares of the Company's common stock at $5.77 per
share. The maximum number of Shares issuable pursuant to the exercise of the
rights contained in the Deferral Agreement is 1,743,559. This conversion right
cannot be exercised if the Offer is consummated before March 31, 2000. In
addition, the Company's Notes are convertible into shares of the Company's
common stock at $8.325 per share. The maximum number of Shares issuable upon
conversion of the Notes is 1,381,382.

    The Company shall take such action as is necessary to cause the ending date
of the then current offering period under the Company's employee stock purchase
plan to be prior to the Effective Time and to terminate such plan as of the
Effective Time.

    INTERIM OPERATIONS; COVENANTS.  Pursuant to the Merger Agreement, the
Company has agreed that, except as expressly contemplated or provided by the
Merger Agreement or in the Company Disclosure Letter delivered by the Company to
Parent and Purchaser in connection with the Merger Agreement or consented to in
writing by Parent (which consent in the case of certain provisions shall not be
unreasonably denied), prior to the Effective Time, (i) the Company shall
conduct, and it shall cause the Company Subsidiaries to conduct, its or their
businesses in the ordinary course and consistent with past practice, and the
Company shall, and it shall cause the Company Subsidiaries to, use its or their
reasonable best efforts to preserve substantially intact its business
organization, to keep available the services of its present officers and
employees and to preserve the present commercial relationships of the Company
and the Company Subsidiaries with persons with whom the Company or the Company
Subsidiaries do significant business and (ii) without limiting the generality of
the foregoing, neither the Company nor any of the Company Subsidiaries will:

    Company or any of the Company Subsidiaries, including, but not limited to,
    any securities convertible into or exchangeable for shares of stock of any
    class of the Company or any of the Company Subsidiaries, except for (a) the
    issuance of shares pursuant to the exercise of Company Options outstanding
    on the date of the Merger Agreement in accordance with their present terms,
    (b) the issuance of shares pursuant to the Company Stock Purchase Plan as in
    effect on the date of the Merger Agreement, (c) the issuance of shares

    declare, pay or set aside any dividend or other distribution (whether in

    (except that in no case may the Company or a Company Subsidiary declare or
    pay any cross-border dividends), make or allow any Company subsidiary to
    make any cross-border capital contributions, or directly or indirectly

                                       28
<PAGE>
    the Company SEC Filings filed prior to the date of the Merger Agreement or
    incurred in the ordinary course of business consistent with past practice;

        (K) except to the extent necessary for the exercise of its fiduciary
    duties by the Board of Directors of the Company as set forth in, and
    consistent with the provisions described under "No Solicitation" below,
    waive, amend or allow to lapse any term or condition of any confidentiality
    or "standstill" agreement to which the Company or any Company Subsidiary is
    a party; or

        (L) take, or agree in writing or otherwise to take, any of the foregoing
    actions or any action which would make any of the representations or
    warranties of the Company contained in the Merger Agreement untrue or
    incorrect in any material respect at or prior to the Effective Time.

The Merger Agreement further provides that the Company shall, and the Company
shall cause each of the Company Subsidiaries to, comply with all Laws applicable
to it or any of its properties, assets or business and to maintain in full force
and effect all the Company Permits necessary for such business, except in any
such case for any failure so to comply or maintain that would not reasonably be
expected to result in a Material Adverse Effect.

    NO SOLICITATION.  Pursuant to the Merger Agreement, the Company shall not,
directly or indirectly, through any officer, director, employee, representative
or agent of the Company or any of the Company Subsidiaries, solicit or encourage
the initiation of (including by way of furnishing information) any inquiries or
proposals regarding any Company Takeover Proposal that if consummated would
constitute an Alternative Transaction (as defined below). The Board of Directors
of the Company is not prevented from (i) furnishing information to a third party
which has made a BONA FIDE Company Takeover Proposal that is a Superior Proposal
(as defined below) not solicited in violation of the Merger Agreement, provided
that such third party has executed an agreement with confidentiality provisions
substantially similar to those then in effect between the Company and an
affiliate of Parent (the "Confidentiality Agreement") or (ii) subject to
compliance with the other terms of the Merger Agreement's "No Solicitation"
provision, considering and negotiating a BONA FIDE Company Takeover Proposal
that is a Superior Proposal not solicited in violation of the Merger Agreement;
PROVIDED THAT, as to each of clauses (i) and (ii), the Board of Directors of the
Company reasonably determines in good faith (after due consultation with
independent counsel, which may be Stoel Rives LLP) that it is or is reasonably
likely to be required to do so in order to discharge properly its fiduciary
duties. For purposes of the Merger Agreement, a "Superior Proposal" means any
proposal made by a party to acquire, directly or indirectly, for consideration
consisting of cash and/or securities, all of the equity securities of the
Company entitled to vote generally in the election of directors or all the
assets of the Company (other than a DE MINIMUS amount of assets not material to
the conduct of the Company's business), on terms which the Board of Directors of
the Company reasonably believes (after consultation with Financial Advisor,
McDonald Investments or another financial advisor of nationally recognized
reputation) to be more favorable from a financial point of view to its
shareholders than the Offer and the Merger taking into account at the time of
determination all factors relating to such proposed transaction deemed relevant
by the Board of Directors of the Company, including, without limitation, the
financing thereof, the proposed timing thereof and all other conditions thereto
and any changes to the financial terms of the Merger Agreement proposed by
Parent and Purchaser. "Alternative Transaction" means any of (i) a transaction
pursuant to which any person (or group of persons) other than Parent or its
affiliates (a "Third Party") acquires or would acquire more than 20% of the
outstanding shares of any class of equity securities of the Company, whether
from the Company or pursuant to a tender offer or exchange offer or otherwise,
(ii) a merger or other business combination involving the Company pursuant to
which any Third Party acquires more than 20% of the outstanding equity
securities of the Company or the entity surviving such merger or business
combination, (iii) any transaction pursuant to which any Third Party acquires or
would acquire control of assets (including for this purpose the outstanding
equity securities of Company Subsidiaries and securities of the entity surviving
any merger or business combination including any of the Company Subsidiaries) of
the Company or any Company Subsidiaries having a fair market value (as
determined by the Board of Directors of the Company in good

                                       29
<PAGE>
faith) equal to more than 20% of the fair market value of all the assets of the
Company and the Company Subsidiaries, taken as a whole, immediately prior to
such transaction, or (iv) any other consolidation, business combination,
recapitalization or similar transaction involving the Company or any of the
Company Subsidiaries, other than the transactions contemplated by this
Agreement; PROVIDED, HOWEVER, that the term Alternative Transaction shall not
include any acquisition of securities by a broker dealer in connection with a
BONA FIDE public offering of such securities. Notwithstanding anything to the
contrary contained in the Merger Agreement, prior to the Effective Time, the
Company may, in connection with a possible Company Takeover Proposal, refer any
third party to the "No Solicitation" and "Fees and Expenses" sections of the
Merger Agreement and make a copy of these sections available to a third party.

    The Merger Agreement requires the Company to immediately notify Parent and
Purchaser after receipt of any Company Takeover Proposal, or any modification of
or amendment to any Company Takeover Proposal, or any request for nonpublic
information relating to the Company or any of the Company Subsidiaries in
connection with a Company Takeover Proposal or for access to the properties,
books or records of the Company or any subsidiary by any person or entity that
informs the Board of Directors of the Company or such subsidiary that it is
considering making, or has made, a Company Takeover Proposal. Such notice to
Parent and Purchaser shall be made orally and in writing, and shall indicate the
identity of the person making the Company Takeover Proposal or intending to make
the Company Takeover Proposal or requesting non-public information or access to
the books and records of the Company, the terms of any such Company Takeover
Proposal or modification or amendment to a Company Takeover Proposal, and
whether the Company is providing or intends to provide the person making the
Company Takeover Proposal with access to information concerning the Company as
provided above. The Company shall also immediately notify Parent and Purchaser,
orally and in writing, if it enters into negotiations concerning any Company
Takeover Proposal.

    Except as set forth in the Merger Agreement, neither the Board of Directors
of the Company nor any committee thereof shall (i) withdraw or modify, or
indicate publicly its intention to withdraw or modify, in a manner adverse to
Parent, the approval or recommendation by such Board of Directors or such
committee of the Offer or the Merger, (ii) approve or recommend, or indicate
publicly its intention to approve or recommend, any Company Takeover Proposal or
(iii) cause the Company to enter into any letter of intent, agreement in
principle, acquisition agreement or other similar agreement (each, a "Company
Acquisition Agreement") related to any Company Takeover Proposal.
Notwithstanding the foregoing, in the event that prior to the Effective Time the
Board of Directors of the Company determines in good faith, after due
consultation with outside counsel, that the failure to do so constitutes or is
reasonably likely to constitute a breach of its fiduciary duties to the
Company's shareholders under applicable law, the Board of Directors of the
Company may approve or recommend a Superior Proposal and, in connection
therewith, withdraw or modify its approval or recommendation of the Offer or the
Company Proposals, but only at a time that is after the third business day
following Parent's receipt of written notice advising Parent that the Board of
Directors of the Company has received a Superior Proposal and, in the case of
any previously received Superior Proposal that has been materially modified or
amended, such modification or amendment and specifying the material terms and
conditions of such Superior Proposal, modification or amendment.

    The Merger Agreement does not restrict the Company from taking and
disclosing to its shareholders a position contemplated by Rule 14e-2(a)
promulgated under the Securities Exchange Act or from making any disclosure to
the Company's shareholders if, in the good faith judgment of the Board of
Directors of the Company, with the advice of outside counsel, failure so to
disclose could be determined to be a breach of its fiduciary duties to the
Company's shareholders under applicable law; PROVIDED, HOWEVER, that neither the
Company nor its Board of Directors nor any committee thereof shall, except as
permitted by the above, withdraw or modify, or indicate publicly its intention
to withdraw or modify, its position with respect to the Offer or the Merger or
approve or recommend, or indicate publicly its intention to approve or
recommend, a Company Takeover Proposal.

                                       30

    The Company shall advise its officers and directors and any investment
banker or attorney retained by the Company in connection with the transactions
contemplated by the Merger Agreement of the restrictions set forth above.

    INDEMNIFICATION AND INSURANCE.  From and after the Effective Time, the
Surviving Corporation shall indemnify and hold harmless all past and present
officers and directors (the "Indemnified Parties") of the Company and of the
Company Subsidiaries to the full extent such persons may be indemnified by the
Company pursuant to Oregon law, the Company's Articles of Incorporation and
Bylaws, as each is in effect on October 26, 1999, for acts and omissions
(x) arising out of or pertaining to the transactions contemplated by the Merger
Agreement or arising out of the Offer Documents or (y) otherwise with respect to
any acts or omissions occurring or arising at or prior to the Effective Time and
shall advance reasonable litigation expenses incurred by such persons in
connection with defending any action arising out of such acts or omissions,
PROVIDED that such persons provide the requisite affirmations and undertaking,
as set forth in applicable provisions of the OBCA.

    In addition, Parent will provide, or cause the Surviving Corporation to
provide, for a period of not less than six years after the Effective Time, the
Company's current directors and officers an insurance and indemnification policy
that provides coverage for events occurring or arising at or prior to the
Effective Time (the "D&O Insurance") that is no less favorable than the existing
policy or, if substantially equivalent insurance coverage is unavailable, the
best available coverage; PROVIDED, HOWEVER, that Parent and the Surviving
Corporation shall not be required to pay an annual premium for the D&O Insurance
in excess of 200% of the annual premium currently paid by the Company for such
insurance, but in such case shall purchase as much such coverage as possible for
such amount.

    The Merger Agreement provides that the foregoing provisions are intended to
benefit the Indemnified Parties and shall be binding on all successors and
assigns of Parent, Purchaser, the Company and the Surviving Corporation. Parent
has agreed to guarantee the performance by the Surviving Corporation of the
indemnified obligations set forth above, which guaranty is absolute and
unconditional and shall not be affected by any circumstance whatsoever,
including the bankruptcy or insolvency of the Surviving Corporation or any
person. The Indemnified Parties shall be intended third-party beneficiaries of
the foregoing provisions on indemnification and insurance.

    REPRESENTATIONS AND WARRANTIES.  Pursuant to the Merger Agreement, the
Company has made customary representations and warranties to Parent and
Purchaser with respect to, among other things, its organization, capitalization,
subsidiaries, authority relative to the Merger Agreement, governmental approvals
with respect to the Merger Agreement, the absence of contractual or legal
violations resulting from the Agreement, securities filings, financial
statements, the absence of material adverse effects on the Company and certain
other events since June 30, 1999, the absence of undisclosed liabilities,

and recalls, customers, interested party transactions, finders and investment
bankers, fairness opinion, takeover statutes, full disclosure, year 2000
readiness, absence of rights agreements and absence of certain unlawful
payments.

    REASONABLE BEST EFFORTS.  Under the Merger Agreement, each of the Company,
Parent and Purchaser has agreed to use reasonable best efforts to take all
actions and to do all things necessary, proper or advisable to consummate and
make effective as promptly as practicable the transactions contemplated by the
Merger Agreement, including, but not limited to, (i) obtaining all consents from
governmental authorities and other third parties required for the consummation
of the Offer and the Merger and the transactions contemplated thereby and
(ii) timely making all necessary filings under the HSR Act. The Company, Parent
and Purchaser have also agreed to use reasonable best efforts to take all
actions and to do all things necessary to satisfy the other conditions of the
closing of the Merger.

                                       31

    PUBLIC ANNOUNCEMENTS.  So long as the Merger Agreement is in effect, the
Company, on the one hand, and Parent and Purchaser, on the other, have agreed
not to issue or cause the publication of any press release or any other
announcement with respect to the Offer or the Merger or the transactions
contemplated thereby without the consent of the other party (such consent not to
be unreasonably withheld or delayed), except where such release or announcement
is required by applicable law or pursuant to any applicable listing agreement
with, or rules or regulations of, any stock exchange on which shares of the
capital stock of the Company or Tyco, as the case may be, are listed or the
NASD, or other applicable securities exchange, in which case the parties will
consult prior to making the announcement.

    TERMINATION; FEES.  The Merger Agreement may be terminated at any time prior
to the Effective Time, whether before or after approval by the shareholders of
the Company of the Merger herein:

        (a) by mutual written consent of Parent and the Company;

        (b) by either Parent or the Company if any Governmental Authority shall
    have issued an order, decree or ruling or taken any other action permanently
    enjoining, restraining or otherwise prohibiting the consummation of the
    transactions contemplated by the Merger Agreement and such order, decree or
    ruling or other action shall have become final and nonappealable;

        (c) by Parent if:

           (i) the Company shall have breached or failed to perform in any
       material respect any of its covenants or other agreements contained in
       the Merger Agreement, which breach or failure to perform is incapable of
       being cured or has not been cured within five days after the giving of
       written notice thereof to the Company (but not later than the expiration
       of the 20 business day period provided for the Offer above);

           (ii) any representation or warranty of the Company shall not have
       been true and correct when made (without for this purpose giving effect
       to qualifications of materiality contained in such representation and
       warranty), if such failure to be true and correct, individually or in the
       aggregate, would reasonably be expected to have a Material Adverse
       Effect;

           (iii) any representation or warranty of the Company shall cease to be
       true and correct at any later date (without for this purpose giving
       effect to qualifications of materiality contained in such representation
       and warranty) as if made on such date (other than representations and
       warranties made as of a specified date) other than as a result of a
       breach or failure to perform by the Company of any of its covenants or
       agreements under the Merger Agreement if such failure to be true and
       correct, individually or in the aggregate, would reasonably be expected
       to have a Material Adverse Effect; PROVIDED, HOWEVER, that such
       representation or warranty is incapable of being cured or has not been
       cured within five days after the giving of written notice thereof to the
       Company (but not later than the expiration of the 20 business day period
       provided for the Offer above);

    PROVIDED, HOWEVER, that the right to terminate the Merger Agreement pursuant
    to this clause (c) shall not be available to Parent if Purchaser or any
    other affiliate of Parent shall acquire Shares pursuant to the Offer;

        (d) by Parent if, whether or not permitted to do so by the Merger

    thereof shall have withdrawn or modified in a manner adverse to Parent or
    Purchaser its approval or recommendation of the Offer or any of the Company
    Proposals; (ii) the Board of Directors of the Company or any committee
    thereof shall have approved or recommended to the shareholders of the
    Company any Company Takeover Proposal or Alternative Transaction; (iii) the

    the Company's shareholders permitted pursuant to the "No Solicitation"
    provisions of the Merger Agreement described above which has the effect of
    any of the foregoing; or (v) the Board of Directors of the Company or any
    committee thereof shall have resolved to take any of the foregoing actions;

        (e) by either Parent or the Company if, as the result of the failure of
    the Minimum Condition or any of the other conditions set forth in
    Section 15, the Offer shall have terminated or expired in accordance with
    its terms without Purchaser having purchased any Shares pursuant to the
    Offer, PROVIDED that if the failure to satisfy any conditions set forth in
    Section 15 shall be a basis for termination of the Merger Agreement under
    any other clause of this section, a termination pursuant to this clause
    shall be deemed a termination under such other clause;

        (f) by either Parent or the Company if the Offer shall not have been
    consummated on or before February 29, 2000, PROVIDED that the right to
    terminate the Merger Agreement pursuant to this clause shall not be
    available to any party whose failure to perform any of its obligations under
    the Merger Agreement results in the failure of the Offer to be consummated
    by such time;

        (g) by the Company, if Parent or Purchaser shall have breached or failed
    to perform in any material respect any of its representations, warranties,
    covenants or other agreements contained in the Merger Agreement, which
    breach or failure to perform is incapable of being cured or has not been
    cured within five days after the giving of written notice thereof to Parent;
    or

        (h) by the Company, in order to accept a Superior Proposal, PROVIDED
    that the Board of Directors of the Company reasonably determines in good
    faith (after due consultation with independent counsel, which may be Stoel
    Rives LLP), that it is or is reasonably likely to be required to accept such
    proposal in order to discharge properly its fiduciary duties; the Company
    has given Parent three business days' advance notice of the Company's
    intention to accept such Superior Proposal; the Company shall in fact accept
    such proposal; the Company shall have paid the fee and expenses contemplated
    by the Merger Agreement; and the Company shall have complied in all respects
    with the provisions of the section regarding "No Solicitation."

    In the event of termination of the Merger Agreement and the abandonment of
the Offer or the Merger, the Merger Agreement (other than certain sections)
shall become void and of no effect with no liability on the part of any party
hereto (or of any of its directors, officers, employees, agents, legal or
financial advisors or other representatives); PROVIDED, HOWEVER, that no such
termination shall relieve any party thereto from any liability for any willful
breach of the Merger Agreement prior to termination. If the Merger Agreement is
terminated as provided herein, each party shall use all reasonable best efforts
to redeliver all documents, work papers and other material (including any copies
thereof) of any other party relating to the transactions contemplated thereby,
whether obtained before or after the execution hereof, to the party furnishing
the same.

    The Company agrees that if the Merger Agreement is terminated pursuant to

        (i) the provisions described in clause (d) above;

        (ii) the provision described in clause (h) above; or

        (iii) the provision described in clause (e) or (f) above and, with
    respect to this clause (iii), (A) at the time of such termination, there
    shall be outstanding a BONA FIDE Company Takeover Proposal which has been
    made directly to the shareholders of the Company or has otherwise become
    publicly known or there shall be outstanding an announcement by any credible
    third party of a BONA FIDE intention to make an Acquisition Proposal (in
    each case whether or not conditional and whether or not such proposal shall
    have been rejected by the Board of Directors of the Company) or (B) an
    Alternative Transaction shall be publicly announced by the Company or any
    third party within 12 months following the date of such termination and such
    transaction shall at any time thereafter be

                                       33
<PAGE>
    consummated on substantially the terms theretofore announced, then the
    Company shall pay to Parent the sum of $5 million. Any payment required by
    this section shall be made as promptly as practicable but in no event later
    than two business days following termination of the Merger Agreement in the
    case of clause (i) above, upon termination of the Merger Agreement in the
    case of clause (ii) above and, in the case of clause (iii) above, upon
    consummation of such Company Takeover Proposal, and shall be made by wire
    transfer of immediately available funds to an account designated by Parent.

    The Company further agrees that if the Merger Agreement is terminated
pursuant to clause (c)(i) above,

        (i)  the Company will pay to Parent, as promptly as practicable but in
    no event later than two business days following termination of the Merger
    Agreement, the amount of all documented and reasonable costs and expenses
    incurred by Parent, Purchaser and their affiliates (including but not
    limited to fees and expenses of counsel and accountants and out-of-pocket
    expenses (but not fees) of financial advisors) in an aggregate amount not to
    exceed $500,000 in connection with the Merger Agreement or the transactions
    contemplated hereby ("Parent Expenses"); and

        (ii)  in the event that the Company consummates a Company Takeover
    Proposal (whether or not solicited in violation of the Merger Agreement)
    which is publicly announced within one year from the date of termination of
    the Merger Agreement, the Company will pay to Parent the sum of $5 million,
    which payment shall be made not later than two business days following
    consummation of such Company Takeover Proposal.

    If the Merger Agreement is terminated pursuant to clause (c)(ii), the
Company will pay to Parent, as promptly as practicable but in no event later
than two business days following termination of the Merger Agreement, the Parent
Expenses.

    GUARANTEE.  Tyco has guaranteed the payment by Purchaser of the Per Share
Amount and any other amounts payable by Purchaser pursuant to the Merger
Agreement and has agreed to cause Purchaser to perform all of its other
obligations under the Merger Agreement in accordance with its terms.

    SHAREHOLDER'S AGREEMENT

    As an inducement to Parent and the Purchaser entering into the Agreement
with the Company, Robert L. Praegitzer (the "Shareholder"), who owns
approximately 53.0% of the Shares on a diluted basis, has entered into a
Shareholder's Agreement (the "Shareholder's Agreement") with Parent and the
Purchaser.

                                       34
<PAGE>
    The following summary of certain provisions of the Shareholder's Agreement,
a copy of which is filed as an exhibit to the Schedule 14D-1, is qualified in
its entirety by reference to the text of the Shareholder's Agreement.

    AGREEMENT TO TENDER.  The Shareholder has agreed that he shall tender his
Shares in the Offer and that he shall not withdraw any Shares so tendered;
PROVIDED, HOWEVER, that if the Shareholder is unable to tender any Shares that
are pledged to KeyBank National Association ("KeyBank") the Shareholder shall
not be obligated to tender such Shares; PROVIDED FURTHER that the Shareholder
shall sell such Shares to Purchaser, and Purchaser shall purchase such Shares
from the Shareholder, at the Per Share Amount prior to the Effective Time
promptly upon termination of the pledge agreements between the Shareholder and
KeyBank relating to such Shares. Purchaser hereby agrees that, if the Offer is
consummated, it will satisfy the liabilities secured by the pledge of Shares to
KeyBank prior to the Effective Time.

    The Shareholder shall tender his Shares (other than the Shares pledged to
KeyBank) not later than fourteen business days following commencement of the
Offer, other than with respect to the Shares subject to the CBL Insured Credit
Facility Agreement (the "CBL Agreement") which shall be tendered not later than
one business day prior to the initially scheduled expiration of the Offer;
PROVIDED, HOWEVER, that if the Shares subject to the CBL Agreement are not
tendered as aforesaid, any damages of Purchaser shall be limited to $5,000,000.

    In connection therewith, the Company has agreed with, and covenanted to,
Parent that the Company shall not register the transfer of any certificate
representing any of the Shareholder's Shares, unless such transfer is made to
Parent or the Purchaser or otherwise in compliance with the Shareholder's
Agreement.

    GRANT OF IRREVOCABLE PROXY.  Subject to the provisions of the pledge
agreements with KeyBank, the Shareholder has irrevocably granted to, and
appointed, Parent and any individual designated by Parent as the Shareholder's
proxy and attorney-in-fact, to vote the Shareholder's Shares, or grant a consent
or approval in respect of the Shares, at any meeting of shareholders of the
Company or in any other circumstances upon which the Shareholder's vote, consent
or other approval is sought, against (i) any merger agreement or merger (other
than the Merger Agreement and the Merger), consolidation, combination, sale of
substantial assets, reorganization, joint venture, recapitalization,
dissolution, liquidation or winding up of or by the Company and (ii) any
amendment of the Company's Articles of Incorporation or Bylaws or other proposal
or transaction (including any consent solicitation to remove or elect any
directors of the Company) involving the Company or any of its subsidiaries,
which amendment or other proposal or transaction would in any manner impede,
frustrate, prevent or nullify, or result in a breach of any covenant,
representation or warranty or any other obligation or agreement of the Company
under or with respect to, the Offer, the Merger, the Merger Agreement or any of
the other transactions contemplated by the Merger Agreement.

    REPRESENTATIONS, WARRANTIES, COVENANTS AND OTHER AGREEMENTS.  The
Shareholder has made certain representations and warranties in the Shareholder's
Agreement, including with respect to (i) ownership of his Shares, (ii) the
authority to enter into and perform his obligations under the Shareholder's
Agreement and the absence of required consents and statutory or contractual
conflicts or violations, (iii) the absence of liens, claims, security interests,
proxies, voting trusts or other arrangements or any other encumbrances on or in
respect of the Shares, except for those disclosed to Purchaser (iv) finder's
fees, and (v) an acknowledgment of Parent's reliance upon the Shareholder's
execution of the Shareholder's Agreement in entering into, and causing Purchaser
to enter into, the Merger Agreement. In addition, the Shareholder has agreed not
to transfer, or consent to any transfer of any or all of the Shareholder's
Shares or any interest therein (except as contemplated by the Shareholder's
Agreement), enter into any contract, option or other agreement or understanding
with respect to any transfer of any or all of his Shares or any interest
therein, grant any proxy, power-of-attorney or other authorization or consent in
or with respect to the Shares or any interest therein except with respect to
election of directors at the Company's annual meeting, deposit the Shares into a
voting trust or enter into a voting arrangement or agreement with

                                       35
<PAGE>
respect to the Shares or take any other action that would in any way restrict,
limit or interfere with its obligations under the Shareholder's Agreement. The
Shareholder has also agreed, directly or indirectly, not to solicit, initiate or
encourage the submission of any Acquisition 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 Acquisition Proposal.

    TERMINATION.  The Shareholder's Agreement, and all rights and obligations
thereunder, shall terminate upon the earlier of (a) the date upon which the
Merger Agreement is terminated in accordance with its terms or (b) the date that
Parent or Purchaser shall have purchased and paid for the Shares of the
Shareholder pursuant to the terms of the Shareholder's Agreement; PROVIDED,
HOWEVER, that the termination of the Shareholder's Agreement shall not relieve
any party of liability for breach of such agreement prior to its termination.

    14. DIVIDENDS AND DISTRIBUTIONS.  As discussed in Section 13, the Merger
Agreement provides that the Company will not take certain actions such as paying
dividends on, or making any other distributions in respect of, any of its
capital stock, splitting, combining, or reclassifying any of its capital stock
or purchasing, redeeming, or otherwise acquiring any shares of capital stock of
the Company.

    If on or after the date of the Merger Agreement and notwithstanding the
provisions thereof, the Company should (i) split, combine or otherwise change
the Shares or its capitalization, (ii) acquire presently outstanding Shares or
otherwise cause a reduction in the number of outstanding Shares or (iii) issue
or sell any shares of any class or any securities convertible into any such
shares, or any rights, warrants or options to acquire any such shares or
convertible securities (other than Shares issued pursuant to, and in accordance
with the terms in effect on the date of the Merger Agreement of, stock options,
warrants or convertible securities issued prior to such date), then, without
prejudice to Purchaser's rights under the Merger Agreement, Purchaser (subject
to the Merger Agreement), in its sole discretion, may make such adjustments in
the Offer price and other terms of the Offer as it deems appropriate to reflect
such action.

    If, on or after the date of the Merger Agreement and notwithstanding the
provisions thereof, the Company should declare or pay any cash, non-cash or
stock dividend or other distribution on, or issue any rights with respect to,
the Shares, payable or distributable to shareholders of record on a date prior
to the transfer to the name of Purchaser or its nominees or transferees on the
Company's stock transfer records of the Shares purchased pursuant to the Offer,
then, without prejudice to Purchaser's rights under the Merger Agreement,
(i) the price per Share payable by Purchaser pursuant to the Offer may, subject
to the provisions of the Merger Agreement, in the sole discretion of Purchaser,
be reduced by the amount of any such cash dividend or distribution and (ii) any
non-cash dividend, distribution or right to be received by the tendering
shareholders will (a) be received and held by the tendering shareholders for the
account of Purchaser and will be required to be promptly remitted and
transferred by each tendering shareholder to the Depositary for the account of
Purchaser, accompanied by appropriate documentation of transfer or (b) at the
direction of Purchaser, be exercised for the benefit of Purchaser, in which case
the proceeds of such exercise will promptly be remitted to Purchaser. Pending
such remittance, Purchaser will be entitled, subject to applicable law, to all
rights and privileges as owner of any such non-cash dividend, distribution or
right or such proceeds and may withhold the entire purchase price or deduct from
the purchase price the amount or value thereof, as determined by Purchaser in
its sole discretion.

    15. CERTAIN CONDITIONS OF THE OFFER.  Notwithstanding any other term of the
Offer or the Merger Agreement, provided that no Shares have theretofore been
accepted for payment or paid for, Purchaser shall not be required to accept for
payment or pay for, subject to any applicable rules and regulations of the
Commission, including Rule 14e-1(c) of the Exchange Act, any Shares and may

exercisable prior to March 1, 2000), shall not have been satisfied (the "Minimum
Condition") or (ii) any applicable waiting period under the HSR Act shall not
have expired or been terminated prior to the expiration of the Offer or
(iii) at any time after the date of the Merger Agreement and before the time of

    contained in such representation and warranty), or the Company shall not in

    complied with each covenant to be performed and complied with by it under
    the Merger Agreement, if such failure to be true and correct or such failure
    to perform, individually or in the aggregate, would reasonably be expected
    to have a Material Adverse Effect, PROVIDED, HOWEVER, that such breach or
    failure to perform is incapable of being cured or has not been cured within
    five days after the giving of written notice thereof to the Company,
    PROVIDED, HOWEVER, that no such 5-day cure period shall require extension of

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

    Should the Offer be terminated pursuant to the foregoing provisions, all
tendered Shares not theretofore accepted for payment shall forthwith be returned
to the tendering shareholders.

    16. CERTAIN LEGAL MATTERS.

    GENERAL.  Except as described in this Section 16, based on a review of
publicly available filings by the Company with the Commision and other publicly
available information concerning the Company, neither Parent nor Purchaser is
aware of any license or regulatory permit that appears to be material to the
business of the Company and that might be adversely affected by Purchaser's
acquisition of Shares pursuant to the Offer, or of any approval or other action
by any governmental, administrative or regulatory agency or authority, domestic
or foreign, that would be required for the acquisition or ownership of Shares by
Purchaser pursuant to the Offer. Should any such approval or other action be
required, it is presently contemplated that such approval or action would be
sought, except as described below under "State Takeover Laws." While Purchaser
does not currently intend to delay acceptance for payment of Shares tendered
pursuant to the Offer pending the outcome of any such matter, there can be no
assurance that any such approval or other action, if required, would be obtained
without substantial conditions or that adverse consequences would not result to
the Company's business or that certain parts of the Company's business would not
have to be disposed of in the event that such approvals were not obtained or
such other actions were not taken or in order to obtain any such approval or
other action. If certain types of adverse

                                       38
<PAGE>
action are taken with respect to the matters discussed below, Purchaser may
decline to accept for payment or pay for any Shares tendered. See Section 15.

    STATE TAKEOVER LAWS.  The Company and certain of its subsidiaries conduct
business in a number of states throughout the United States, some of which have
adopted laws and regulations applicable to offers to acquire shares of
corporations that are incorporated or have substantial assets, shareholders
and/or a principal place of business in such states. In EDGAR V. MITE CORP., the
Supreme Court of the United States held that the Illinois Business Takeover
Statute, which involved state securities laws that made the takeover of certain
corporations more difficult, imposed a substantial burden on interstate commerce
and was therefore unconstitutional. In CTS CORP. V. DYNAMICS CORP. OF AMERICA,
however, the Supreme Court of the United States held that a state may, as a
matter of corporate law and, in particular, those laws concerning corporate
governance, constitutionally disqualify a potential acquiror from voting on the
affairs of a target corporation without prior approval of the remaining
shareholders, PROVIDED that such laws were applicable only under certain
conditions, in particular, that the corporation has a substantial number of
shareholders in and is incorporated under the laws of such state.

    The Company is incorporated under the laws of the State of Oregon. In
general, Sections 60.825-60.845 of the OBCA ("Section 60.825") prevent an
"interested shareholder" (including a person who owns or has the right to
acquire 15% or more of the corporation's outstanding voting stock) from engaging
in a "business combination" (defined to include mergers and certain other
actions) with an Oregon corporation for a period of three years following the
date such person became an interested shareholder. The Board of Directors of the
Company has taken all appropriate action so that neither Parent nor Purchaser is
an "interested shareholder" pursuant to Section 60.825.

    The Company was subject to the Oregon Control Share Act (the "Control Share
Act"). The Control Share Act generally provides that a person (the "Acquiror")
who acquires voting stock of an Oregon corporation in a transaction (other than
a transaction in which voting shares are acquired from the issuing public
corporation) that results in the Acquiror holding more than 20%, 33 1/3% or 50%
of the total voting power of the corporation (a "Control Share Acquisition")
cannot vote the shares it acquires in the Control Share Acquisition except in
certain circumstances. The Company's Board of Directors, at its meeting on
October 25, 1999, amended the Company's Bylaws to provide that the Control Share
Act shall not apply to the Company.

    Neither Parent nor Purchaser has determined whether any other state takeover
laws and regulations will by their terms apply to the Offer, and, except as set
forth above, neither Parent nor Purchaser has presently sought to comply with
any state takeover statute or regulation. Parent and Purchaser reserve the right
to challenge the applicability or validity of any state law or regulation
purporting to apply to the Offer or the Merger, and neither anything in this
Offer nor any action taken in connection herewith is intended as a waiver of
such right. In the event it is asserted that one or more state takeover statutes
is applicable to the Offer or the Merger and an appropriate court does not
determine that such statute is inapplicable or invalid as applied to the Offer
or the Merger, Parent or Purchaser might be required to file certain information
with, or to receive approval from, the relevant state authorities, and Purchaser
might be unable to accept for payment or pay for Shares tendered pursuant to the
Offer, or be delayed in consummating the Offer.

    ANTITRUST.  Under the HSR Act and the rules that have been promulgated
thereunder by the Federal Trade Commission (the "FTC"), certain acquisition
transactions may not be consummated unless certain information has been
furnished to the Antitrust Division of the Department of Justice (the "Antitrust
Division") and the FTC and certain waiting period requirements have been
satisfied. The acquisition of Shares by Purchaser pursuant to the Offer is
subject to such requirements. See Section 15.

    Under the provisions of the HSR Act applicable to the purchase of Shares
pursuant to the Offer, purchases may not be consummated until the expiration of
a 15-calendar day waiting period after the filing of certain required
information and documentary material with the Antitrust Division and the FTC
with

                                       39
<PAGE>
respect to the Offer (unless earlier terminated pursuant to a request therefor,
which Parent will make). If, within such 15-day waiting period, either the
Antitrust Division or the FTC requests additional information or documentary
material relevant to the Offer from Parent, the waiting period will be extended
for an additional period of 10 calendar days following the date of substantial
compliance with such request. Only one extension of the waiting period pursuant
to a request for additional information is authorized by the rules promulgated
under the HSR Act. Thereafter, such waiting period may be extended only by court
order or by agreement of Parent. A request for additional information issued to
the Company cannot extend the waiting period. Tyco, as the ultimate parent of
Purchaser, expects to file a Notification and Report Form with respect to the
Offer under the HSR Act on November 2, 1999, and, in such event, the required
waiting period with respect to the Offer will expire at 11:59 p.m., New York
City time, on November 17, 1999, unless Tyco receives a request for additional
information or documentary material or the Antitrust Division or the FTC
terminates the waiting period prior thereto.

    The Antitrust Division and the FTC frequently scrutinize the legality under
the antitrust laws of transactions such as the proposed purchase of Shares by
Purchaser pursuant to the Offer. At any time before or after such purchase, the
Antitrust Division or the FTC could take such action under the antitrust laws as
it deems necessary or desirable in the public interest, including seeking to
enjoin the transaction or seeking divestiture of the Shares so acquired or
divestiture of substantial assets of Parent or its subsidiaries. Litigation
seeking similar relief could also be brought by private persons and the state
attorneys general.

    Based upon an examination of publicly available information relating to the
businesses in which Tyco and the Company are engaged, Parent and Purchaser do
not believe that consummation of the Offer will result in violation of any
applicable antitrust laws. However, there can be no assurance that a challenge
to the Offer on antitrust grounds will not be made, or, if such a challenge is
made, what the result would be. See Section 15 for certain conditions to the
Offer, including conditions with respect to certain judicial or governmental
actions.

    17. FEES AND EXPENSES.  Purchaser has retained Morrow & Co., Inc. to act as
the Information Agent and ChaseMellon Shareholder Services, L.L.C. to act as the
Depositary in connection with the Offer. The Information Agent may contact
holders of Shares by mail, telephone, telex, telecopy and personal interview and
may request brokers, dealers and other nominee shareholders to forward the Offer
materials to beneficial owners. The Information Agent and the Depositary will
receive reasonable and customary compensation for services relating to the Offer
and will be reimbursed for certain out-of-pocket expenses. Purchaser and Parent
have also agreed to indemnify the Information Agent and the Depositary against
certain liabilities and expenses in connection with the Offer, including certain
liabilities under the federal securities laws.

    Neither Parent nor Purchaser will pay any fees or commissions to any broker
or dealer or any other person (other than to the Information Agent) for
soliciting tenders of Shares pursuant to the Offer. Brokers, dealers, commercial
banks and trust companies will, upon request, be reimbursed by Purchaser for
customary mailing and handling expenses incurred by them in forwarding offering
materials to their customers.

    18. MISCELLANEOUS.  The Offer is being made to all holders of Shares.
Purchaser is not aware of any jurisdiction where the making of the Offer is
prohibited by administrative or judicial action pursuant to any valid state
statute. If Purchaser becomes aware of any valid state statute prohibiting the
making of the Offer or the acceptance of Shares pursuant thereto, Purchaser will
make a good faith effort to comply with any such state statute or seek to have
such statute declared inapplicable to the Offer. If, after such good faith
effort, Purchaser cannot comply with any such state statute, the Offer will not
be made to (nor will tenders be accepted from or on behalf of) the holders of
Shares in such state. In any jurisdiction where the securities, blue sky or
other laws require the Offer to be made by a licensed broker or dealer, the
Offer will be deemed to be made on behalf of Purchaser by one or more registered
brokers or dealers licensed under the laws of such jurisdiction.

    No person has been authorized to give any information or make any
representation on behalf of Parent, Purchaser or the Company not contained in
this Offer to Purchase or in the related Letter of Transmittal and, if given or
made, such information or representation must not be relied upon as having been
authorized.

    Parent and Purchaser have filed with the Commission a Tender Offer Statement
on Schedule 14D-1, together with all exhibits thereto, pursuant to Rule 14d-3 of
the General Rules and Regulations under the Exchange Act, furnishing certain
additional information with respect to the Offer. Such Tender Offer Statement
and any amendments thereto, including exhibits, may be inspected and copies may
be obtained from the offices of the Commission in the manner set forth in
Section 8 (except that they will not be available at the regional offices of the
Commission).

Ladies and Gentlemen:

    The undersigned hereby tenders to T Merger Sub (OR), Inc., an Oregon
corporation ("Purchaser") and a wholly owned subsidiary of Sigma
Circuits, Inc., a Delaware corporation ("Sigma") and an indirect wholly-owned
subsidiary of Tyco International Ltd., a Bermuda company ("Tyco"), the
above-described shares of common stock (the "Shares"), of Praegitzer
Industries, Inc., an Oregon corporation (the "Company"), pursuant to Purchaser's
offer to purchase all of the outstanding Shares at a price of $5.50 per Share,
net to the tendering shareholder in cash, upon the terms and subject to the
conditions set forth in the Offer to Purchase, dated November 1, 1999 (the
"Offer to Purchase"), receipt of which is hereby acknowledged, and in this
Letter of Transmittal (which together constitute the "Offer"). Tyco fully and
unconditionally guarantees the Offer. Purchaser reserves the right to transfer
or assign, in whole or from time to time in part, to Tyco or to one or more
affiliates of Tyco, the right to purchase Shares tendered pursuant to the Offer.

    Subject to, and effective upon, acceptance for payment of and payment for
the Shares tendered herewith in accordance with the terms and subject to the
conditions of the Offer, the undersigned hereby sells, assigns, and transfers
to, or upon the order of, Purchaser all right, title and interest in and to all
of the Shares that are being tendered hereby (and any and all other Shares or
other securities or rights issued or issuable in respect thereof on or after
November 1, 1999) and irrevocably appoints the Depositary the true and lawful
agent and attorney-in-fact of the undersigned with respect to such Shares (and
any such other Shares or securities or rights), with full power of substitution
(such power of attorney being deemed to be an irrevocable power coupled with an
interest), to (a) deliver certificates representing such Shares (and any such
other Shares or securities or rights), or transfer ownership of such Shares (and
any such other Shares or securities or rights) on the account books maintained
by DTC, together in either such case with all accompanying evidences of transfer
and authenticity, to or upon the order of Purchaser upon receipt by the
Depositary, as the undersigned's agent, of the purchase price (adjusted, if
appropriate, as provided in the Offer to Purchase), (b) present such Shares (and
any such other Shares or securities or rights) for registration and transfer on
the books of the Company, and (c) receive all benefits and otherwise exercise
all rights of beneficial ownership of such Shares (and any such other Shares or
securities or rights), all in accordance with the terms of the Offer.

                                       3

    The undersigned hereby irrevocably appoints Mark H. Swartz, Mark A. Belnick
and any other designee of Purchaser, the attorneys and proxies of the
undersigned, each with full power of substitution, to vote in such manner as
each such attorney and proxy or his substitute shall, in his sole discretion,
deem proper, and otherwise act (including pursuant to written consent) with
respect to all the Shares tendered hereby which have been accepted for payment
by Purchaser prior to the time of such vote or action (and any and all other
Shares or securities or rights issued or issuable in respect thereof on or after
November 1, 1999), which the undersigned is entitled to vote at any meeting of
shareholders (whether annual or special and whether or not an adjourned meeting)
of the Company, or consent in lieu of any such meeting, or otherwise. This proxy
and power of attorney is coupled with an interest in the Shares tendered hereby
and is irrevocable and is granted in consideration of, and is effective upon,
the acceptance for payment of such Shares (and any such other Shares or
securities or rights) by Purchaser in accordance with the terms of the Offer.
Such acceptance for payment shall revoke all prior proxies granted by the
undersigned at any time with respect to such Shares (and any such other Shares
or securities or rights) and no subsequent proxies will be given (and if given
will be deemed not to be effective) with respect thereto by the undersigned. The
undersigned acknowledges that in order for Shares to be deemed validly tendered,
immediately upon the acceptance for payment of such Shares, Purchaser or
Purchaser's designee must be able to exercise full voting and other rights of a
record and beneficial holder with respect to such Shares.

    The undersigned hereby represents and warrants that the undersigned has full
power and authority to tender, sell, assign and transfer the Shares tendered
hereby (and any and all other Shares or securities or rights issued or issuable
in respect thereof on or after November 1, 1999), and that, when the same are
accepted for payment by Purchaser, Purchaser will acquire good and unencumbered
title thereto, free and clear of all liens, restrictions, charges and
encumbrances and the same will not be subject to any adverse claim. The
undersigned, upon request, will execute and deliver any additional documents
deemed by the Depositary or Purchaser to be necessary or desirable to complete
the sale, assignment and transfer of the Shares tendered hereby (and any such
other Shares or securities or rights).

    No authority herein conferred or agreed to be conferred in this Letter of
Transmittal shall be affected by, and all such authority shall survive, the
death or incapacity of the undersigned, and any obligation of the undersigned
hereunder shall be binding upon the successors, assigns, heirs, executors,
administrators and legal representatives of the undersigned. Except as stated in
the Offer to Purchase, this tender is irrevocable.

    The undersigned understands that tenders of Shares pursuant to any one of
the procedures described in Section 2 of the Offer to Purchase and in the
instructions hereto will constitute a binding agreement between the undersigned
and Purchaser upon the terms and subject to the conditions of the Offer.

    The undersigned recognizes that, under certain circumstances set forth in
the Offer to Purchase, Purchaser may not be required to accept for payment any
of the Shares tendered hereby.

    Unless otherwise indicated herein under "Special Payment Instructions,"
please issue the check for the purchase price and/or return any certificates
representing Shares not tendered or accepted for payment in the name(s) of the
registered holder(s) appearing under "Description of Shares Tendered."
Similarly, unless otherwise indicated under "Special Delivery Instructions,"
please mail the check for the purchase price and/or return any certificates
representing Shares not tendered or accepted for payment (and accompanying
documents, as appropriate) to the registered holder(s) appearing under
"Description of Shares Tendered" at the address shown below such registered
holder(s) name(s). In the event that either or both the Special Delivery
Instructions and the Special Payment Instructions are completed, please issue
the check for the purchase price and/or return any certificates representing
Shares not tendered or accepted for payment in the name(s) of, and deliver such
check and/or return such certificates to, the person or persons so indicated.
Shareholders tendering Shares by book entry transfer may request that any Shares
not accepted for payment be returned by crediting such account maintained at DTC
such shareholder may designate by making an appropriate entry under "Special
Payment Instructions." The undersigned recognizes that Purchaser has no
obligation pursuant to the Special Payment Instructions to transfer any Shares
from the name of the registered holder(s) thereof if Purchaser does not accept
for payment any of the Shares so tendered hereby.

                                  INSTRUCTIONS
             FORMING PART OF THE TERMS AND CONDITIONS OF THE OFFER

    1.  GUARANTEE OF SIGNATURES.  No signature guarantee on this Letter of
Transmittal is required (i) if this Letter of Transmittal is signed by the
registered holder(s) of the Shares (which term, for purposes of this document,
shall include any participant in DTC whose name appears on a security position
listing as the owner of Shares) tendered herewith, unless such holder has
completed either the box entitled "Special Delivery Instructions" or the box
entitled "Special Payment Instructions" on this Letter of Transmittal, or
(ii) if such Shares are tendered for the account of a firm that is a member in
good standing of the Security Transfer Agent's Medallion Program, the New York
Stock Exchange Medallion Signature Program or the Stock Exchange Medallion
Program (each being hereinafter referred to as an "Eligible Institution"). In
all other cases, all signatures on this Letter of Transmittal must be guaranteed
by an Eligible Institution. See Instruction 5.

    2.  DELIVERY OF LETTER OF TRANSMITTAL AND CERTIFICATES.  This Letter of
Transmittal is to be completed by shareholders either if certificates
representing Shares are to be forwarded herewith to the Depositary or, unless an
Agent's Message (as defined below) is utilized, if tenders of Shares are to be
made pursuant to the procedures for delivery by book-entry transfer set forth in
Section 2 of the Offer to Purchase. Certificates representing all physically
tendered Shares, or any book-entry confirmation of Shares, as the case may be,
together with a properly completed and duly executed Letter of Transmittal (or
facsimile thereof), with any required signature guarantees, or, in connection
with a book-entry transfer, an Agent's Message, and any other documents required
by this Letter of Transmittal, must be received by the Depositary at one of its
addresses set forth herein on or prior to the Expiration Date (as defined in
Section 1 of the Offer to Purchase). If a shareholder's certificate(s)
representing Shares are not immediately available (or the procedure for the
book-entry transfer cannot be completed on a timely basis) or time will not
permit all required documents to reach the Depositary on or prior to the
Expiration Date, such shareholder's Shares may nevertheless be tendered if the
procedures for guaranteed delivery set forth in Section 2 of the Offer to
Purchase are followed. Pursuant to such procedure, (i) such tender must be made
by or through an Eligible Institution, (ii) a properly completed and duly
executed Notice of Guaranteed Delivery, substantially in the form provided by
Purchaser, must be received by the Depositary on or prior to the Expiration
Date, and (iii) the certificates representing all tendered Shares, in proper
form for transfer, or Book-Entry Confirmation of Shares, as the case may be, in
each case together with a properly completed and duly executed Letter of
Transmittal (or facsimile thereof), with any required signature guarantees (or,
in connection with a book-entry transfer, an Agent's Message) and any other
documents required by this Letter of Transmittal, must be received by the
Depositary within three Nasdaq Stock Market trading days after the date of
execution of such Notice of Guaranteed Delivery, all as provided in Section 2 of
the Offer to Purchase. The term "Agent's Message" means a message transmitted
through electronic means by DTC to, and received by, the Depositary and forming
a part of a Book-Entry Confirmation, which states that DTC has received an

    6.  STOCK TRANSFER TAXES.  Except as set forth in this Instruction 6,
Purchaser will pay or cause to be paid any stock transfer taxes with respect to

certificates representing Shares not tendered or accepted for payment are to be
registered in the name of, any person other than the registered holder, or if
tendered certificates are registered in the name of any person other than the
person(s) signing this Letter of Transmittal, the amount of any stock transfer
taxes (whether imposed on the registered holder or such other person) payable on

address other than that shown above, the appropriate boxes on this Letter of
Transmittal should be completed. Shareholders tendering Shares by book-entry

    8.  LOST, DESTROYED OR STOLEN CERTIFICATES.  If any certificate(s)
representing Shares has been lost, destroyed or stolen, the shareholder should
promptly notify the Depositary. The shareholder will then be instructed as to
the steps that must be taken in order to replace the certificate(s). This Letter
of Transmittal and related documents cannot be processed until the procedures
for replacing lost or destroyed certificates have been followed.

    9.  WAIVER OF CONDITIONS.  The conditions of the Offer may be waived by
Purchaser, in whole or in part, at any time and from time to time in Purchaser's
sole discretion (subject to the provisions of the Merger Agreement referred to
in the Offer to Purchase), in the case of any Shares tendered hereby.

    10.  SUBSTITUTE FORM W-9.  The tendering shareholder is required to provide
the Depositary with a correct Taxpayer Identification Number ("TIN"), generally
the shareholder's social security or federal employer identification number, on
Substitute Form W-9, which is provided below, and to certify whether the
shareholder is subject to backup withholding of United States federal income
tax. If a tendering shareholder is subject to backup withholding, the
shareholder must cross out item (2) of the Certification box of the Substitute
Form W-9. Failure to provide the information on the Substitute Form W-9 may
subject the tendering shareholder to 31% Federal income tax withholding on the
payment of the purchase price. If the tendering shareholder has not been issued
a TIN and has applied for a number or intends to apply for a number in the near
future, the shareholder should write "Applied For" in the space provided for the
TIN in Part I, and sign and date the Substitute Form W-9. If "Applied For" is
written in Part I and the Depositary is not provided with a TIN within 60 days,
the Depositary will withhold 31% on all payments of the purchase price until a
TIN is provided to the Depositary.

    11.  NON-UNITED STATES HOLDERS.  Non-United States holders must submit a
completed IRS Form W-8 or Form W-8BEN to avoid backup withholding. IRS Form W-8
or Form W-8BEN may be obtained by contacting the Depositary at one of the
addresses on the face of this Letter of Transmittal.

    12.  REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.  Requests for assistance
may be directed to the Information Agent at the address set forth below.
Additional copies of the Offer to Purchase, this Letter of Transmittal, the
Notice of Guaranteed Delivery and the Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9 may be obtained from the
Information Agent at the address set forth below or from your broker, dealer,
commercial bank or trust company.

    IMPORTANT:  This Letter of Transmittal (or a facsimile thereof), together
with certificates representing Shares or confirmation of book-entry transfer and
all other required documents, or the Notice of Guaranteed Delivery, must be
received by the Depositary on or prior to the Expiration Date.

                           IMPORTANT TAX INFORMATION

    Under United States federal income tax law, a shareholder whose tendered
Shares are accepted for payment is required to provide the Depositary (as payer)
with such shareholder's correct Taxpayer Identification Number ("TIN") on
Substitute Form W-9 below. If such shareholder is an individual, the TIN is such
person's social security number. The TIN of a resident alien who does not have
and is not eligible to obtain a social security number is such person's IRS
individual taxpayer identification number. If a tendering shareholder is subject
to backup withholding, the shareholder must cross out item (2) of the
Certification box on the Substitute Form W-9. If the Depositary is not provided
with the correct TIN, the shareholder may be subject to a $50 penalty imposed by
the Internal Revenue Service ("IRS"). In addition, payments that are made to
such shareholder with respect to Shares purchased pursuant to the Offer may be
subject to backup withholding.

                                       9
<PAGE>
    CERTAIN SHAREHOLDERS (INCLUDING, AMONG OTHERS, ALL CORPORATIONS AND CERTAIN
NON-UNITED STATES INDIVIDUALS) ARE NOT SUBJECT TO BACKUP WITHHOLDING. IN ORDER
FOR A NON-UNITED STATES INDIVIDUAL TO QUALIFY AS AN EXEMPT RECIPIENT, THAT
SHAREHOLDER MUST SUBMIT TO THE DEPOSITARY A PROPERLY COMPLETED IRS FORM W-8 OR
FORM W-8BEN, SIGNED UNDER PENALTIES OF PERJURY, ATTESTING TO THAT INDIVIDUAL'S
EXEMPT STATUS. SUCH FORMS MAY BE OBTAINED FROM THE DEPOSITARY. EXEMPT
SHAREHOLDERS, OTHER THAN NON-UNITED STATES INDIVIDUALS, SHOULD FURNISH THEIR
TIN, WRITE "EXEMPT" ON THE FACE OF THE SUBSTITUTE FORM W-9 BELOW, AND SIGN, DATE
AND RETURN THE SUBSTITUTE FORM W-9 TO THE DEPOSITARY. SEE THE ENCLOSED
GUIDELINES FOR CERTIFICATION OF TAXPAYER IDENTIFICATION NUMBER ON SUBSTITUTE
FORM W-9 FOR ADDITIONAL INSTRUCTIONS.

    IF BACKUP WITHHOLDING APPLIES, THE DEPOSITARY IS REQUIRED TO WITHHOLD 31% OF
ANY PAYMENTS MADE TO THE SHAREHOLDER. BACKUP WITHHOLDING IS NOT AN ADDITIONAL
TAX. RATHER, THE TAX LIABILITY OF PERSONS SUBJECT TO BACKUP WITHHOLDING WILL BE
REDUCED BY THE AMOUNT OF TAX WITHHELD. IF WITHHOLDING RESULTS IN AN OVERPAYMENT
OF TAXES, A REFUND MAY BE OBTAINED FROM THE IRS.

PURPOSE OF SUBSTITUTE FORM W-9

    To prevent backup withholding on payments that are made to a shareholder
with respect to Shares purchased pursuant to the Offer, the shareholder is
required to notify the Depositary of such shareholder's correct TIN by
completing the Substitute Form W-9 below certifying that the TIN provided on
such form is correct (or that such shareholder is awaiting a TIN) and that
(i) such holder is exempt from backup withholding, (ii) such holder has not been
notified by the IRS that such holder is subject to backup withholding as a
result of a failure to report all interest or dividends, or (iii) the IRS has
notified such holder that such holder is no longer subject to backup withholding
(see Part 2 of Substitute Form W-9).

WHAT NUMBER TO GIVE THE DEPOSITARY

    The shareholder is required to give the Depositary the social security
number, individual taxpayer identification number, or employer identification
number of the record owner of the Shares. If the Shares are in more than one
name or are not in the name of the actual owner, consult the enclosed Guidelines
for Certification of Taxpayer Identification Number on Substitute Form W-9 for
additional guidelines on which number to report. If the tendering shareholder
has not been issued a TIN and has applied for a number or intends to apply for a
number in the near future, such shareholder should write "Applied For" in the
space provided for in the TIN in Part 1, and sign and date the Substitute
Form W-9. If "Applied For" is written in Part 1 and the Depositary is not
provided with a TIN within 60 days, the Depositary may withhold 31% on all
payments of the purchase price until a TIN is provided to the Depositary.

BECAUSE THE PLEDGED SHARES ARE NOT RELEASED FROM CERTAIN PLEDGE ARRANGEMENTS
BEFORE THE CONSUMMATION OF THE OFFER, THE MAJORITY SHAREHOLDER HAS AGREED TO

    procedures for book-entry transfer cannot be completed on a timely basis.

        6. Guidelines of the Internal Revenue Service for Certification of

    is conditioned upon, among other things, there being validly tendered and
    not withdrawn prior to the expiration of the offer at least that number of
    Shares which would constitute 51% of the outstanding Shares on a diluted
    basis. The majority shareholder of the Company who owns 8,119,375 Shares

    shareholder is unable to tender 2,656,500 of these Shares (the "Pledged
    Shares") in the Offer (constituting approximately 17.4% of the outstanding

accepted for

                                       2

Section 2 of the Offer to Purchase), (ii) a properly completed and duly executed
Letter of Transmittal (or facsimile thereof) with any required signature
guarantees (or, in connection with a book-entry transfer, an Agent's Message (as
defined in Section 2 of the Offer to Purchase)), and (iii) all other documents
required by the Letter of Transmittal.

of the Offer, a tender may be effected by following the guaranteed delivery
procedures specified under Section 2, "Procedure for Tendering Shares," in the

To Our Clients:

    Enclosed for your consideration is an Offer to Purchase, dated November 1,
1999 (the "Offer to Purchase"), and the related Letter of Transmittal (which
together constitute the "Offer") relating to the offer by T Merger Sub
(OR), Inc., an Oregon corporation ("Purchaser") and a wholly owned subsidiary of
Sigma Circuits, Inc., a Delaware corporation ("Sigma") and an indirect
wholly-owned subsidiary of Tyco International Ltd., a Bermuda company ("Tyco"),
to purchase all of the outstanding shares of common stock (the "Shares"), of
Praegitzer Industries, Inc., an Oregon corporation (the "Company"), at a price
of $5.50 per Share, net to the seller in cash, upon the terms and subject to the
conditions set forth in the Offer. Tyco fully and unconditionally guarantees the
Offer. The Offer is being made in connection with the Agreement and Plan of
Merger, dated as of October 26, 1999, among Sigma, Purchaser and the Company and
the related guarantee of Tyco.

    WE ARE THE HOLDER OF RECORD (DIRECTLY OR INDIRECTLY) OF SHARES FOR YOUR
ACCOUNT. A TENDER OF SUCH SHARES CAN BE MADE ONLY BY US OR OUR NOMINEES AS THE
HOLDER OF RECORD AND PURSUANT TO YOUR INSTRUCTIONS. THE LETTER OF TRANSMITTAL IS
FURNISHED TO YOU FOR YOUR INFORMATION ONLY AND CANNOT BE USED BY YOU TO TENDER
SHARES HELD BY US FOR YOUR ACCOUNT.

    We request instructions as to whether you wish to have us tender on your
behalf any or all of the Shares held by us for your account, pursuant to the
terms and conditions set forth in the Offer.

    Your attention is directed to the following:

    1. The tender price is $5.50 per Share, net to you in cash.

    2. THE BOARD OF DIRECTORS OF THE COMPANY HAS DETERMINED THAT THE OFFER AND
THE MERGER (AS DEFINED IN THE OFFER TO PURCHASE) ARE FAIR TO, AND IN THE BEST
INTERESTS OF, THE COMPANY AND ITS SHAREHOLDERS, HAS APPROVED THE MERGER
AGREEMENT, THE OFFER AND THE MERGER, AND RECOMMENDS THAT THE HOLDERS OF SHARES
ACCEPT THE OFFER AND TENDER THEIR SHARES PURSUANT TO THE OFFER.

    3. The Offer and withdrawal rights will expire at 12:00 Midnight, New York
City time, on Tuesday, November 30, 1999, unless the Offer is extended.

    4. The Offer is being made for all of the outstanding Shares. The offer is
conditioned upon, among other things, there being validly tendered and not
withdrawn prior to the expiration of the offer at least that number of Shares
which would constitute 51% of the outstanding Shares on a diluted basis. The
majority shareholder of the company who owns 8,119,375 Shares (constituting
approximately 53.0% of the
<PAGE>
outstanding Shares on a diluted basis) has agreed to tender these Shares in the
Offer. If the majority shareholder is unable to tender 2,656,500 of these Shares
(the "Pledged Shares") in the Offer (constituting approximately 17.4% of the
outstanding Shares on a diluted basis) because the Pledged Shares are not
released from certain pledge arrangements before the consummation of the Offer,
the majority shareholder has agreed to sell to Purchaser the Pledged Shares
following consummation of the Offer upon the release of the Pledged Shares from
the pledge arrangements to which they are subject.

    5. Shareholders who tender Shares will not be obligated to pay brokerage
fees, commissions or, except as set forth in Instruction 6 of the Letter of
Transmittal, transfer taxes on the purchase of Shares by Purchaser pursuant to
the Offer.

sign and return the instruction form set forth below. An envelope to return your
instructions to us is enclosed. If you authorize the tender of your Shares, all
such Shares will be tendered unless otherwise specified on the instruction form
set forth below. PLEASE FORWARD YOUR INSTRUCTIONS TO US AS SOON AS POSSIBLE TO
ALLOW US AMPLE TIME TO TENDER YOUR SHARES ON YOUR BEHALF PRIOR TO THE EXPIRATION
OF THE OFFER.

    The Offer is made solely by the Offer to Purchase and the related Letter of
Transmittal and any supplements and amendments thereto. Purchaser is not aware
of any state where the making of the Offer is prohibited by administrative or
judicial action pursuant to any valid state statute. If Purchaser becomes aware
of any valid state statute prohibiting the making of the Offer or the acceptance
of Shares pursuant thereto, Purchaser will make a good faith effort to comply
with any such state statute or seek to have such statute declared inapplicable
to the Offer. If, after such good faith effort, Purchaser cannot comply with any
such state statute, the Offer will not be made to (nor will tenders be accepted
from or on behalf of) the holders of Shares in such state. In any jurisdiction
where the securities, blue sky or other laws require the Offer to be made by a
licensed broker or dealer, the Offer will be deemed to be made on behalf of
Purchaser by one or more registered brokers or dealers licensed under the laws
of such jurisdiction.

             PRAEGITZER INDUSTRIES, INC. ANNOUNCES CASH ACQUISITION
                           BY TYCO INTERNATIONAL LTD.

         Tualatin, OR and Hamilton, Bermuda, October 26, 1999 - Praegitzer
Industries, Inc. (NASDAQ-PGTZ), a leading designer and manufacturer of complex

they have entered into a definitive Merger Agreement pursuant to which Tyco will
acquire, for cash, all of the outstanding common shares of Praegitzer at a price
of $5.50 per share.

         "After a review of possibilities, the Praegitzer Board of Directors
determined that being acquired by Tyco was the best course of action for our
shareholders, employees and customers," stated Matt Bergeron, president and
chief operating officer of Praegitzer Industries, Inc. Bergeron continued, "Our
operations, enhanced by Tyco's financial strength and breadth of product
offerings, will provide a stable environment and exciting opportunity for
Praegitzer employees, suppliers and customers. In addition, the combination of
Praegitzer Industries and Tyco International will create one of the world's
foremost global printed circuit board design and manufacturing companies.
Together we can provide our customers with a more comprehensive range of
integrated solutions to accommodate the rapid growth of the technological adept
interconnect market on a global basis."

         "Praegitzer is an excellent fit with the Tyco Printed Circuit Group
(TPCG). First, the combination of Praegitzer's volume commercial production
facilities with ours creates solid opportunities in the data networking and
telecommunications markets. Second, the addition of Praegitzer's quick-turn
capability clearly positions TPCG as the leader in this attractive market.
Finally, Praegitzer's design centers will enhance our ability to provide
advanced circuit board design support for the newest generation of electronics
from our Tyco Submarine Systems undersea telecommunications business," said
L. Dennis Kozlowski, Tyco's Chairman and Chief Executive Officer. Mr. Kozlowski
also noted that the acquisition will provide an immediate positive contribution
to Tyco's earnings.

         Under the Agreement, a subsidiary of Tyco will shortly commence a
tender offer to purchase all of Praegitzer's 13,129,751 shares of common stock
for $5.50 per share in cash, for a total of approximately $72 million. The
tender offer will be followed by a merger in which each of the remaining shares
of Praegitzer will be exchanged for $5.50 in cash.

         The offer will be made pursuant to definitive offering documents to be
filed with the Securities and Exchange Commission. The offer is conditioned on
the tender of the majority of the outstanding shares of common stock on a fully
diluted basis, as well as certain other conditions.

FORWARD LOOKING INFORMATION

         Comments in this release concerning Tyco's expected fiscal 2000

growth of the interconnect market and the stability of the environment created
by the acquisition are forward-looking statements, which are based on
management's good faith expectations and belief concerning future developments.
Actual results may materially differ from these expectations as a result of many
factors, relevant examples of which are set forth in Praegitzer's 1999 Annual
Report on Form 10-K and in the "Management Discussion and Analysis" section of
Tyco's 1998 Annual Report to Shareholders and the Tyco's 1998 Annual Report on

                            TYCO INTERNATIONAL LTD.


          T Merger Sub (OR), Inc. an Oregon corporation (the "Purchaser") and a
wholly owned subsidiary of Sigma Circuits, Inc. ("Sigma"), a Delaware
corporation and an indirect subsidiary of Tyco International Ltd., a Bermuda
company ("Tyco"), is offering to purchase all outstanding shares of common stock
(the "Shares") of Praegitzer Industries Inc., an Oregon corporation (the
"Company"), at $5.50 per Share, net to the seller in cash (the "Offer Price"),
upon the terms and subject to the conditions set forth in the Offer to Purchase,
dated November 1, 1999, and in the related Letter of Transmittal (which together
constitute the "Offer"). Tyco fully and unconditionally guarantees the Offer.

- --------------------------------------------------------------------------------
         THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00 MIDNIGHT,
       NEW YORK CITY TIME, ON TUESDAY, NOVEMBER 30, 1999, UNLESS EXTENDED.
- --------------------------------------------------------------------------------

          The Offer is conditioned upon, among other things, there being validly
tendered and not withdrawn prior to the expiration of the Offer at least that
number of Shares which would constitute 51% of the outstanding Shares on a
diluted basis (the "Minimum Condition"). The majority shareholder of the Company
who owns 8,119,375 Shares (constituting approximately 53.0% of the outstanding
Shares on a diluted basis) has agreed to tender these Shares in the Offer. If
the majority shareholder is unable to tender 2,656,500 of these Shares (the
"Pledged Shares") in the Offer (constituting approximately 17.4% of the
outstanding Shares on a diluted basis) because the Pledged Shares are not
released from certain pledge arrangements before the consummation of the Offer,
the majority shareholder has agreed to sell to the Purchaser the Pledged Shares
following consummation of the Offer upon the release of the Pledged Shares from
the pledge arrangements to which they are subject.

          The Offer is being made pursuant to an Agreement and Plan of Merger,
dated as of October 26, 1999 (the "Merger Agreement"), among Sigma, the
Purchaser and the Company and the related guarantee of Tyco, pursuant to which,
following the consummation of the Offer and the satisfaction or waiver of
certain conditions, the Purchaser will be merged with and into the Company (the
"Merger"). At the effective time of the Merger, each outstanding Share (other
than Shares owned by Tyco, Sigma, the Purchaser or any other wholly owned
subsidiary of Tyco or held by shareholders, if any, who are entitled to and who
properly exercise dissenters' rights under Oregon law) will be converted into
the right to receive the Offer Price without interest.

          The Board of Directors of the Company has determined that the Offer
and the Merger are fair to, and in the best interests of, the Company and its
shareholders, has approved the Merger Agreement, the Offer and the Merger, and
recommends that the holders of the Shares accept the Offer and tender their
Shares pursuant to the Offer.

          For purposes of the Offer, the Purchaser will be deemed to have
accepted for payment, and thereby purchased, Shares properly tendered to the
Purchaser and not withdrawn as, if and when the Purchaser gives oral or written
notice to ChaseMellon Shareholder Services, L.L.C. (the "Depositary") of the
Purchaser's acceptance for payment of such Shares. Upon the terms and subject to
the conditions of the Offer, payment for Shares purchased pursuant to the Offer
will be made by deposit of the purchase price therefor with the Depositary,
which will act as agent for tendering shareholders for the purpose of receiving
payment from the Purchaser and transmitting payment to tendering shareholders.
In all cases, payment for Shares purchased pursuant to the Offer will be made
only after timely receipt by the Depositary of (a) certificates for such Shares
or timely confirmation of book-entry transfer of such Shares into the
Depositary's account at The Depository Trust Company ("DTC") pursuant to the
procedures set forth in Section 2 of the Offer to Purchase, (b) a properly
completed and duly executed Letter of Transmittal (or facsimile thereof) with
any required signature guarantees and (c) any other documents required by the
Letter of Transmittal. Under no circumstances will interest be paid by the
Purchaser on the purchase price of the Shares, regardless of any extension of
the Offer or any delay in making such payment.

          The term "Expiration Date" means 12:00 Midnight, New York City time,
on Tuesday, November 30, 1999, unless and until the Purchaser, in its sole
discretion (but subject to the terms of the Merger Agreement), shall have
extended the period of time during which the Offer is open, in which event the
term "Expiration Date" shall mean the latest time and date at which the Offer,
as so extended by the Purchaser, shall expire. The Purchaser expressly reserves
the right, in its sole discretion (but subject to the terms of the Merger
Agreement), at any time or from time to time, and regardless of whether or not
any of the events set forth in Section 15 of the Offer to Purchase shall have
occurred or shall have been determined by the Purchaser to have occurred, to
extend the period of time during which the Offer is open and thereby delay
acceptance for payment of, and the payment for, any Shares, by giving oral or
written notice of such extension to the Depositary. The Purchaser shall not have
any obligation to pay interest on the purchase price for tendered Shares in the
event the Purchaser exercises its right to extend the period of time during
which the Offer is open. There can be no assurance that the Purchaser will
exercise its right to extend the Offer. Any such extension will be followed by a
public announcement thereof no later than 9:00 A.M., New York City time, on the
next business day after the previously scheduled Expiration Date. During any
such extension, all Shares previously tendered and not withdrawn will remain
subject to the Offer, subject to the right of a tendering shareholder to
withdraw such shareholder's Shares.

          Except as otherwise provided below, tenders of Shares are irrevocable.
Shares tendered pursuant to the Offer may be withdrawn at any time prior to
12:00 Midnight, New York City time, on Tuesday, November 30, 1999 (or, if the
Purchaser shall have extended the period of time during which the Offer is open,
the latest time and date at which the Offer, as so extended by the Purchaser,
shall expire) and, unless theretofore accepted for payment and paid for by the
Purchaser pursuant to the Offer, may also be withdrawn at any time on or after
January 1, 2000. For a withdrawal to be effective, a written, telegraphic or
facsimile transmission notice of withdrawal must be timely received by the
Depositary at one of its addresses set forth on the back cover of the Offer to
Purchase and must specify the name of the person having tendered the Shares to
be withdrawn, the number of Shares to be withdrawn and the name of the
registered holder of the Shares to be withdrawn, if different from the name of
the person who tendered the Shares. If certificates for Shares have been
delivered or otherwise identified to the Depositary, then, prior to the physical
release of such certificates, the serial numbers shown on such certificates must
be submitted to the Depositary and, unless such Shares have been tendered by an
Eligible Institution (as defined in Section 2 of the Offer to Purchase), the
signatures on the notice of withdrawal must be guaranteed by an Eligible
Institution. If Shares have been delivered pursuant to the procedures for
book-entry transfer as set forth in Section 2 of the Offer to Purchase, any
notice of withdrawal must also specify the name and number of the account at DTC
to be credited with the withdrawn Shares and otherwise comply with DTC's
procedures. Withdrawals of tenders of Shares may not be rescinded, and any
Shares properly withdrawn will thereafter be deemed not validly tendered for
purposes of the Offer. However, withdrawn Shares may be retendered by again
following one of the procedures described in Section 2 of the Offer to Purchase
at any time prior to the Expiration Date.

          The Offer to Purchase and the related Letter of Transmittal and other
relevant materials will be mailed to record holders of Shares and furnished to
brokers, dealers, banks, trust companies and similar persons whose names, or the
names of whose nominees, appear on the shareholder lists or, if applicable, who
are listed as participants in a clearing agency's security position listing, for
subsequent transmittal to beneficial owners of Shares.

          The information required to be disclosed by Rule 14d-6(e)(1)(vii)
under the Securities Exchange Act of 1934, as amended, is contained in the Offer
to Purchase and is incorporated herein by reference.

          THE OFFER TO PURCHASE AND THE RELATED LETTER OF TRANSMITTAL CONTAIN
IMPORTANT INFORMATION AND SHOULD BE READ IN THEIR ENTIRETY BEFORE ANY DECISION
IS MADE WITH RESPECT TO THE OFFER.

          Requests for copies of the Offer to Purchase and the Letter of
Transmittal may be directed to the Information Agent as set forth below, and
copies will be furnished promptly at the Purchaser's expense.

                     THE INFORMATION AGENT FOR THE OFFER IS:

May 3, 1999

PERSONAL & CONFIDENTIAL

Mr. Brian Roussell
Chief Financial Officer
Tyco Printed Circuit Group Inc.
11 Tyco Drive
Stafford Springs, CT 06076[cad 220]0100

Re: Confidentiality Agreement (the "Agreement")

Dear Brian:

     1. You have requested information about Praegitzer Industries, Inc., (the
"Company") in connection with your consideration of a possible transaction
with the Company (a "Transaction"). As a condition to our furnishing such
information to you, we are requiring that you agree, as set forth below, to
treat confidentially such information and any other information that the
Company, its agents or its representatives (including attorneys and financial
advisors) furnishes to you or your directors, officers, employees, agents,
advisors, prospective bank or institutional lenders, affiliates or
representatives of your agents, advisors or prospective lenders (all of the
foregoing collectively referred to as "your Representatives"), whether
furnished before or after the date of this letter, whether communicated in
writing or orally or gathered by inspection, and all notes, analyses,
compilations, studies or other documents, whether prepared by you or others,
which contain or otherwise reflect such information and such information
shall include but not be limited to information developed by you or your
Representatives from plant visits or interviews with customers, suppliers or
employees (collectively, the "Evaluation Material").

     2. The term "Evaluation Material" does not include information which
(i) becomes generally available to the public other than as a result of a
disclosure by you or your Representatives, (ii) was available to you on a
non-confidential basis prior to its disclosure to you by the Company, its
representatives or its agents, (iii) becomes available to you on a
non[cad 220]confidential basis from a source other than the Company, its
representatives or its agents, provided that such source is not bound by a
confidentiality agreement with the Company, its representatives or its agents
or otherwise prohibited from transmitting the information to you or your
Representatives by a contractual, legal or fiduciary obligation, or (iv) was
independently developed by you without access to or the benefit of the
Evaluation Material.

     3. It is understood that you may disclose any of the Evaluation Material
to those of your Representatives who require such material for the purpose of
evaluating a possible Transaction (provided that such Representatives shall
be informed by you of the confidential nature of the Evaluation Material).
You agree that you and your Representatives will keep the Evaluation Material
confidential from any employee of the Company, except with the specific prior
consent of the Company, Adams, Harkness & Hill, Inc. or McDonald Investments,
Inc. or as otherwise permitted by the terms hereof. You further agree that
you and your Representatives will not use any of the Evaluation Material for
any reason or purpose other than to evaluate a possible Transaction.

     4. Without the prior written consent of the Company, you and your
Representatives will not disclose to any person (i) the fact that the
Evaluation Material has been made available to you or that you have

<PAGE>

inspected any portion of the Evaluation Material, (ii) the fact that any
discussions or negotiations are taking place concerning a possible
Transaction, or (iii) any of the terms, conditions or other facts with
respect to any possible Transaction, including the status thereof, unless and
only to the extent that such disclosure (after making reasonable efforts to
avoid such disclosure and after advising and consulting with the Company
about your intention to make, and the proposed contents of, such disclosure)
is, in the opinion of your counsel, which shall promptly be provided to the
Company in writing, required by applicable United States securities laws. The
term "person" as used in this letter shall be broadly interpreted to include
without limitation any corporation, company, partnership and individual.

     5. In the event that you or any of your Representatives are requested or
required (by oral questions, interrogatories, requests for information or
documents, subpoena, Civil Investigative Demand or similar process) to
disclose any of the Evaluation Material, it is agreed that you or such
Representative, as the case may be, will provide the Company with prompt
notice in writing of such request(s) so that it may seek an appropriate
protective order or other appropriate remedy and/or waive your or such
Representative's compliance with the provisions of this Agreement. In the
event that such protective order or other remedy is not obtained, or that the
Company grants a waiver hereunder, you or such Representative may furnish
that portion (and only that portion) of the Evaluation Material which, in the
written opinion of your counsel, you are legally compelled to disclose and
will exercise your best efforts to obtain reliable assurance that
confidential treatment will be accorded any Evaluation Material so furnished.

     6. Without the prior written consent of the Company and except for
communications with Adams, Harkness and Hill, Inc. or McDonald Investments,
Inc., (i) neither you nor those of your Representatives who are aware of the
Evaluation Material and/or the possibility of a Transaction will initiate or
cause to be initiated any communications with any customer, supplier or
employee of the Company concerning the Evaluation Material or any possible
Transaction or any other matter concerning the Company and (ii) none of your
directors, officers or employees who are aware of the Evaluation Material
and/or the possibility of a Transaction will, for the one (1) year period
from the date of this letter agreement, either directly or indirectly solicit
or cause to be solicited the employment of or hire any employee of the
Company, unless such employee is responding to a bona fide advertisement for
employment placed by you in a newspaper or trade publication of general
circulation; provided, however, that the foregoing provision will not prevent
you from employing any person who ceases to be employed by the Company for
the previous three (3) months and that nothing herein shall preclude you from
hiring any such employee who initiates contact with you or responds to any
advertisements or general solicitation that is not specifically targeted at
such person. In addition, the provisions in this Section 6 shall not apply
to the hiring of any Company employee earning less than $20.00 per hour.

     7. You will not copy or remove from the Company's premises any data,
documents, reports or other materials without the Company's express approval.
If you determine that you will not proceed with the Transaction or a
Transaction is not consummated by you, or upon the written request of the
Company, you will promptly deliver to the Company all documents or other
materials furnished by the Company to you or your Representatives
constituting Evaluation Material, together with all copies thereof in the
possession of you or your Representatives. In the event of such request, all
other documents, studies, analyses, compilations or other matter reflecting
or constituting Evaluation Material in the possession of you or your
Representatives will be destroyed, with any such destruction confirmed by you
in writing to the Company.

     8. You hereby acknowledge that you are aware that the securities of the
Company are traded publicly. You hereby acknowledge that you are aware, and
that you will advise each of your Representatives and such other persons who
are informed by you as to the matters which are the subject of this letter,
that the United States securities laws prohibit any person who has received
material, non-public information from an issuer concerning the matters which
are the subject of this letter from purchasing or selling securities of such
issuer or from communicating such information to any other person under
circumstances in which it is reasonably foreseeable that such person is
likely to purchase or sell such securities.

     9. In further consideration of our furnishing you with Evaluation
Material, you also agree that, for a period of two (2) years from the date of
this letter agreement, neither you nor any of your Representatives, without
the prior written consent of the Company, will:

        (a) acquire, offer to acquire, or agree to acquire, directly or
     indirectly, by purchase or otherwise, any voting securities or direct or
     indirect rights to acquire any voting securities of the Company, or of
     any successor to or otherwise, any voting securities or direct or
     indirect rights to acquire any voting securities of the Company, or of
     any successor to or person(s) in control of the Company, other than
     voting securities acquired solely for investment purposes totaling less
     than one percent (1%) of any such entity's outstanding voting
     securities, or any assets of the Company or any subsidiary or division
     thereof or of any such successor or controlling person;

        (b) make, or in any way participate, directly or indirectly, in any
     "solicitation" or "proxies" to vote (as such terms are used in the rules
     of the Securities and Exchange Commission), or seek to advise or
     influence any person or entity in respect of the voting of any voting
     securities of the Company;

        (c) make any public announcement in respect of or submit a proposal
     for, or offer of (with or without conditions) any extraordinary
     transaction involving the Company or its securities or assets;

        (d) seek or propose to influence or control the Company's management
     or policies; or

        (e) form, join or in any way participate in a "group" as defined in
     Section 13 (d) (3) of the Securities Exchange Act of 1934, as
     amended (the "Exchange Act"), in connection with any of the foregoing.

     You promptly will advise the Company of any inquiry or proposal made to
you in respect of any of the foregoing paragraph 9. You also agree that the
Company will be entitled to equitable relief, including but not limited to
injunctive relief, in the event of any breach of the provisions of these
paragraphs.

     If a third party not affiliated with Tyco Printed Circuit Group Inc.
("Tyco") or any of its affiliates shall have (i) acquired or agreed to
acquire beneficial ownership of at least 10% of the outstanding shares of
capital stock of the Company, which acquisition was not induced directly or
indirectly by Tyco or any of its affiliates, and shall have filed a
Schedule 13D under the Exchange Act with the Securities and Exchange
Commission that sets forth a present intent that is other than passive in all
material respects, provided that an acquisition for investment purposes only
shall be deemed passive, or (ii) commenced or publicly announced its
intention to commence a tender or exchange offer for more than 20% of the
outstanding shares of capital stock of the Company, Tyco shall not be bound
by clauses (a) through (e) of this Section 9 unless the foregoing
third party shall have, in the case of clause (i) above, reduced its
beneficial ownership of the outstanding shares of the capital stock to below
10% or, in the case of clause (ii) above, terminated or publicly announced
its intention to terminate the tender offer, or the tender offer has
otherwise expired, without the purchase by such third party of at least 20%
of the outstanding shares of capital stock of the Company.

     10. You understand that the Company has endeavored to include in the
Evaluation Material information known to it which it believes to be relevant
for the purpose of your investigation, and you further understand that
neither the Company nor its agents or its representatives makes any
representation or warranty as to the accuracy or completeness of the
Evaluation Material. You agree that neither the Company nor its agents or its
representatives makes any representation or warranty as to the accuracy or
completeness of the Evaluation Material. You agree that neither the Company
nor its agents or its representatives shall have any liability to you or any
of your Representatives resulting from the use of the Evaluation Material by
you or such Representatives. Only those representations and warranties that
may be made to you or your affiliates in a definitive written agreement for a
Transaction, when, as and if executed and subject to such limitations and
restrictions as may be specified therein, shall have any legal effect, and
you agree that if you determine to engage in a Transaction such determination
will be based solely on the terms of such written agreement and on your own
investigation, analysis and assessment of


                                       3

the business to be acquired. Moreover, unless and until such a definitive
written agreement is entered into, none of the Company, its affiliates or you
will be under any legal obligation of any kind whatsoever with respect to
such a Transaction except for the matters specifically agreed to in this
Agreement. The agreements set forth in this Agreement may be modified or
waived only by a separate writing signed by the Company and you expressly so
modifying or waiving such agreements.

     11. You hereby agree to indemnify and hold harmless the Company from any
damage, loss, cost or liability (including legal fees and the cost of
enforcing this indemnity) arising out of or resulting from any unauthorized
use or disclosure by you or your Representatives of the Evaluation Material.
You also acknowledge that money damages would be both incalculable and an
insufficient remedy for any breach of this Agreement by you or your
Representatives and that any such breach would cause the Company irreparable
harm. Accordingly, you also agree that in the event of any breach or
threatened breach of this Agreement, the Company, in addition to any other
remedies at law or in equity it may have, shall be entitled, without the
requirement of posting a bond or other security, to equitable relief,
including injunctive relief and specific performance.

     12. It is understood and agreed that no failure or delay by the Company
in exercising any right, power or privilege hereunder shall operate as a
waiver thereof, nor shall any single or partial exercise thereof preclude any
other or further exercise thereof or the exercise of any right, power or
privilege hereunder.

     13. The invalidity or unenforceability of any provision of this
Agreement shall not affect the validity or enforceability of any other
provisions of this letter agreement, which shall remain in full force and
effect.

     14. The rights and obligations provided by this Agreement shall expire
on the second anniversary of the date first above written.

     15. You agree and consent to personal jurisdiction and service and venue
in any federal or state court within the State of Oregon having subject
matter jurisdiction, for the purposes of any action, suit or proceeding
arising out of or relating to this Agreement. This Agreement shall be
governed by and construed in accordance with the laws of the State of Oregon,
without giving effect to the conflict of laws provisions thereof.

     16. If you are in agreement with the foregoing, please sign and return
one copy of this letter, which thereupon will constitute our Agreement with
respect to the subject matter hereof.


Very truly yours,

                          AGREEMENT AND PLAN OF MERGER

         This Agreement and Plan of Merger (this "AGREEMENT") is made and
entered into as of October 26, 1999, by and among Sigma Circuits, Inc.,
("PARENT"), a Delaware company and an indirect subsidiary of Tyco International
Ltd., a Bermuda company ("GUARANTOR"), T Merger Sub (OR), Inc., an Oregon
corporation and a direct wholly owned subsidiary of Parent ("PURCHASER"), and
Praegitzer Industries, Inc., an Oregon corporation (the "COMPANY").

                              W I T N E S S E T H:

                  WHEREAS, the respective Boards of Directors of the Company,
Purchaser and Parent have approved the acquisition by Purchaser of the Company;
and

                  WHEREAS, in furtherance thereof, it is proposed that Purchaser
will make a cash tender offer (the "OFFER") to acquire all of the issued and
outstanding shares of common stock of the Company ("COMMON SHARES"), for $5.50
per share, or such higher price as may be paid in the Offer (the "PER SHARE
AMOUNT"), subject to any applicable withholding, net to the seller in cash
without interest; and

                  WHEREAS, also in furtherance of such acquisition, the
respective Boards of Directors of the Company, Purchaser and Parent have each
approved the merger (the "MERGER") of Purchaser with and into the Company
following the Offer in accordance with the laws of the State of Oregon; and

                  WHEREAS, concurrently with the execution of this Agreement and
as an inducement to Parent to enter into this Agreement, Parent, Purchaser and
the majority shareholder of the Company are entering into a Shareholder's
Agreement pursuant to which such holder has, among other things, agreed to
tender all of his Common Shares in the Offer, upon the terms and subject to the
conditions set forth in the Shareholder's Agreement; and

                  WHEREAS, concurrently with the execution and delivery of this
Agreement, and as a condition to the Company's willingness to enter into this
Agreement, Guarantor has agreed fully and unconditionally to guarantee the
representations, warranties, covenants, agreements and other obligations of
Parent and Purchaser in this Agreement (the "GUARANTEE"); and

                  WHEREAS, the Board of Directors of the Company has approved
and resolved to recommend acceptance of the Offer and the Merger to the holders
of Common Shares and has determined that the consideration to be paid for each
Share in the Offer and the Merger is fair to and in the best interest of the
holders of Common Shares and to recommend that the holders of such Common Shares
accept the Offer and that the holders of Common Shares approve this Agreement
and the transactions contemplated hereby; and

                                       -6-


<PAGE>



                  WHEREAS, the Company, Purchaser and Parent desire to make
certain representations, warranties and agreements in connection with, and
establish various conditions precedent to, the transactions contemplated hereby;

                  NOW, THEREFORE, in consideration of the premises and the
representations, warranties, covenants and agreements hereinafter set forth, the
parties hereto agree as follows:

                                    ARTICLE I
                             TENDER OFFER AND MERGER

                  1.1 THE OFFER. (a) Provided that this Agreement shall not have
been terminated in accordance with SECTION 7.1 hereof and that none of the
events set forth in ANNEX I hereto shall have occurred and be existing,
Purchaser shall commence (within the meaning of Rule 14d-2 under the Securities
Exchange Act of 1934, as amended, and the rules and regulations thereunder (the
"SECURITIES EXCHANGE ACT")) the Offer as promptly as practicable, but in no
event later than five business days following the first public announcement of
the Offer, and shall use reasonable best efforts to consummate the Offer. The
obligation of Purchaser to accept for payment any Common Shares tendered shall
be subject to the satisfaction of only those conditions set forth in ANNEX I
hereto. The Per Share Amount payable in the Offer shall be net to each seller in
cash, subject to reduction only for any applicable withholding or stock transfer
taxes payable by such seller. The Company agrees that no Common Shares held by
the Company or any Company Subsidiaries (as defined below) will be tendered
pursuant to the Offer.

                  (b) Without the prior written consent of the Company,
Purchaser shall not (i) decrease the Per Share Amount or change the form of
consideration payable in the Offer, (ii) decrease the number of Common Shares
sought in the Offer, (iii) amend or waive satisfaction of the Minimum Condition
(as defined in ANNEX I hereto) or (iv) impose additional conditions to the Offer
or amend any other term of the Offer in any manner adverse to the holders of the
Common Shares. The Offer shall initially expire twenty (20) business days after
the date of its commencement, unless this Agreement is terminated in accordance
with SECTION 7.1 hereof, in which case the Offer (whether or not previously
extended in accordance with the terms hereof) shall expire on such date of
termination. Purchaser agrees that it shall not terminate or withdraw the Offer
or extend the expiration date of the Offer unless at the expiration date of the
Offer the conditions to the Offer described in ANNEX I hereto shall not have
been satisfied or earlier waived. Notwithstanding the foregoing, Purchaser may,
without the consent of the Company, extend the Offer at any time, and from time
to time, (i) if at the then scheduled expiration date of the Offer any of the
conditions to Purchaser's obligation to accept for payment and pay for Common
Shares shall not have been satisfied or waived, until such time as such
conditions are satisfied or waived; (ii) for any period required by any rule,
regulation, interpretation or position of the Securities and Exchange Commission
(the "SEC") or its staff applicable to the Offer; or (iii) if all conditions to
Purchaser's

                                       -7-


<PAGE>



obligation to accept for payment and pay for Common Shares are satisfied or
waived but the number of Common Shares tendered is less than 90% of the then
outstanding number of Common Shares, for an aggregate period of not more than
ten (10) business days (for all such extensions) beyond the latest expiration
date that would be permitted under clause (i) or (ii) of this sentence.

                  (c) The Offer shall be made by means of an offer to purchase
(the "OFFER TO PURCHASE") having only the conditions set forth in ANNEX I
hereto. As soon as practicable on the date the Offer is commenced, Purchaser
shall file with 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 that will comply in all material respects with the provisions of,
and satisfy in all material respects the requirements of, such Schedule 14D-1
and all applicable federal securities laws and will contain (including as an
exhibit) or incorporate by reference the Offer to Purchase and forms of the
related letter of transmittal and summary advertisement (which documents,
together with any supplements or amendments thereto, and any other SEC schedule
or form which is filed in connection with the Offer and related transactions,
are referred to collectively herein as the "OFFER DOCUMENTS"). Each of Parent,
Purchaser and the Company agrees promptly to correct any information provided by
it for use in the Schedule 14D-1 or the Offer Documents if and to the extent
that such information shall have become false or misleading in any material
respect and to supplement the information provided by it specifically for use in
the Schedule 14D-1 or the Offer Documents to include any information that shall
become necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading, and Purchaser further
agrees to take all steps necessary to cause the Schedule 14D-1, as so corrected
or supplemented, to be filed with the SEC and the Offer Documents, as so
corrected or supplemented, to be disseminated to holders of Common Shares, in
each case as and to the extent required by applicable federal securities laws.
The Company and its counsel shall be given a reasonable opportunity to review
and comment on any Offer Documents before they are filed with the SEC, and
Parent and Purchaser shall consider any such comments in good faith.

                  (d) Upon the terms and subject to the conditions of the Offer,
Purchaser shall accept for payment and pay for Common Shares as soon as
permitted under the terms of the Offer and applicable law.

                  1.2 COMPANY ACTION. (a) The Company hereby approves and
consents to the Offer and represents and warrants that the Board of Directors of
the Company, at a meeting duly called and held on October 25, 1999, at which all
of the Directors was present, duly approved and adopted this Agreement and the
transactions contemplated hereby, including the Offer and the Merger,
recommended that shareholders of the Company accept the Offer, tender their
Common Shares pursuant to the Offer and approve this Agreement and the
transactions contemplated hereby, including the Merger, and determined that this
Agreement and the transactions contemplated hereby, including the Offer and the
Merger, are fair

                                       -8-


<PAGE>



to and in the best interests of the shareholders of the Company. The Company
hereby consents to the inclusion in the Offer Documents of such recommendation
of the Board of Directors of the Company. The Company represents that its Board
of Directors has received the written opinion (the "FAIRNESS OPINION") of Adams,
Harkness & Hill, Inc. (the "FINANCIAL ADVISOR") that the proposed consideration
to be received by the holders of Common Shares pursuant to the Offer and the
Merger is fair to such holders from a financial point of view. The Company has
been authorized by the Financial Advisor to permit, subject to the prior review
and consent by the Financial Advisor (such consent not to be unreasonably
withheld), the inclusion of the Fairness Opinion (or a reference thereto) in the
Offer Documents, the Schedule 14D-9 (as hereinafter defined) and the Proxy
Statement (as hereinafter defined).

                  (b) The Company shall file with the SEC, as promptly as
practicable after the filing by Parent of the Schedule 14D-1 with respect to the
Offer, a Tender Offer Solicitation/ Recommendation Statement on Schedule 14D-9
(together with any amendments or supplements thereto, the "SCHEDULE 14D-9") that
will comply in all material respects with the provisions of all applicable
federal securities laws. The Company shall mail such Schedule 14D-9 to the
shareholders of the Company as promptly as practicable after the commencement of
the Offer. The Schedule 14D-9 and the Offer Documents shall contain the
recommendations of the Board of Directors of the Company described in SECTION
1.2(a) hereof. The Company agrees promptly to correct the Schedule 14D-9 if and
to the extent that it shall become false or misleading in any material respect
(and each of Parent and Purchaser, with respect to written information supplied
by it specifically for use in the Schedule 14D-9, shall promptly notify the
Company of any required corrections of such information and cooperate with the
Company with respect to correcting such information) and to supplement the
information contained in the Schedule 14D-9 to include any information that
shall become necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading, and the Company shall
take all steps necessary to cause the Schedule 14D-9 as so corrected or
supplemented to be filed with the SEC and disseminated to holders of Common
Shares to the extent required by applicable federal securities laws. Purchaser
and its counsel shall be given a reasonable opportunity to review and comment on
the Schedule 14D-9 before it is filed with the SEC, and the Company shall
consider any such comments in good faith.

                  (c) In connection with the Offer, the Company shall promptly
upon execution of this Agreement furnish Purchaser with mailing labels
containing the names and addresses of all record holders of Common Shares and
security position listings of Common Shares held in stock depositories, each as
of a recent date, and shall promptly furnish Purchaser with such additional
information reasonably available to the Company, including updated lists of
shareholders, mailing labels and security position listings, and such other
information and assistance as Purchaser or its agents may reasonably request for
the purpose of communicating the Offer to the record and beneficial holders of
Common Shares. Subject to the requirements of applicable law and except as
necessary to disseminate the Offer Documents and otherwise for the purpose of
effecting the transactions contemplated hereby,


                                      -9-


<PAGE>



Parent and Purchaser shall hold in confidence the materials furnished pursuant
to this SECTION 1.2(c), use such information only in connection with the Offer,
the Merger and the other transactions contemplated by this Agreement and, if
this Agreement is terminated, as promptly as practicable return to the Company
such materials and all copies thereof in the possession of Parent and Purchaser.

                  1.3 DIRECTORS. Promptly upon the purchase by Parent of Common
Shares pursuant to the Offer (and provided that the Minimum Condition has been
satisfied), Parent shall be entitled to designate such number of directors,
rounded up to the next whole number, on the Board of Directors of the Company as
will give Parent, subject to compliance with Section 14(f) of the Securities
Exchange Act, representation on the Board of Directors of the Company equal to
at least that number of directors which equals the product of the total number
of directors on the Board of Directors of the Company (giving effect to the
directors appointed or elected pursuant to this sentence and including current
directors serving as officers of the Company) multiplied by the percentage that
the aggregate number of Common Shares beneficially owned by Parent or any
affiliate of Parent (including for purposes of this SECTION 1.3 such Common
Shares as are accepted for payment pursuant to the Offer, but excluding Common
Shares held by the Company) bears to the number of Common Shares outstanding. At
such time, if requested by Parent, the Company will also cause each committee of
the Board of Directors of the Company to include persons designated by Parent
constituting the same percentage of each such committee as Parent's designees
are of the Board of Directors of the Company. The Company shall, upon request by
Parent, promptly increase the size of the Board of Directors of the Company or
exercise reasonable best efforts to secure the resignations of such number of
directors as is necessary to enable Parent's designees to be elected to the
Board of Directors of the Company in accordance with the terms of this SECTION
1.3 and to cause Parent's designees so to be elected; PROVIDED, HOWEVER, that,
in the event that Parent's designees are appointed or elected to the Board of
Directors of the Company, until the Effective Time (as hereinafter defined) the
Board of Directors of the Company shall have at least two directors who are
directors on the date hereof, one of whom will be Robert Praegitzer and one of
whom will be a director who is neither an officer of the Company nor a designee,
shareholder, affiliate or associate (within the meaning of the federal
securities laws) of Guarantor (such directors, the "INDEPENDENT DIRECTORS").
Subject to applicable law, the Company shall promptly take all action necessary
pursuant to Section 14(f) of the Securities Exchange Act and Rule 14f-1
promulgated thereunder in order to fulfill its obligations under this SECTION
1.3 and shall include in the Schedule 14D-9 mailed to shareholders promptly
after the commencement of the Offer (or in an amendment thereof or an
information statement pursuant to Rule 14f-1 if Parent has not theretofore
designated directors) such information with respect to the Company and its
officers and directors as is required under Section 14(f) and Rule 14f-1 in
order to fulfill its obligations under this SECTION 1.3. Parent will supply the
Company, and be solely responsible for, any information with respect to itself
and its nominees, officers, directors and affiliates required by such Section
14(f) and Rule 14f-1. Notwithstanding anything in this Agreement to the
contrary, subsequent to the designation of the directors by Parent referred to
in the first sentence of this

                                      -10-


<PAGE>


Section 1.3 and prior to the Effective Time, the unanimous vote of the
Independent Directors shall be required to (i) amend or terminate this Agreement
on behalf of the Company, (ii) exercise or waive any of the Company's rights or
remedies hereunder, (iii) extend the time for performance of Parent's
obligations hereunder, (iv) take any other action by the Company in connection
with this Agreement required to be taken by the Board of Directors of the
Company or (v) amend the Company's Second Amended and Restated Articles of
Incorporation or the Company's Bylaws, each as in effect on the date of this
Agreement.

                  1.4 THE MERGER. Upon the terms and subject to the conditions
of this Agreement, the Merger shall be consummated in accordance with the Oregon
Business Corporation Act (the "OREGON CODE"). At the Effective Time (as defined
in SECTION 1.5 hereof), upon the terms and subject to the conditions of this
Agreement, Purchaser shall be merged with and into the Company in accordance
with the Oregon Code and the separate existence of Purchaser shall thereupon
cease, and the Company, as the surviving corporation in the Merger (the
"SURVIVING CORPORATION"), shall continue its corporate existence under the laws
of the State of Oregon as an indirect subsidiary of Parent. The parties shall
prepare and execute articles of merger (the "ARTICLES OF MERGER") that comply in
all respects with the requirements of the Oregon Code and with the provisions of
this Agreement.

                  1.5 EFFECTIVE TIME. The Merger shall become effective at the
time of the filing of the Articles of Merger with the Secretary of State of
Oregon in accordance with the applicable provisions of the Oregon Code or at
such later time as may be specified in the Articles of Merger. As soon as
practicable after all of the conditions set forth in ARTICLE VI of this
Agreement have been satisfied or waived by the party or parties entitled to the
benefit of the same, the parties hereto shall cause the Merger to become
effective. Parent and the Company shall mutually determine the time of such
filing and the place where the closing of the Merger (the "CLOSING") shall
occur. The time when the Merger shall become effective is herein referred to as
the "EFFECTIVE TIME," and the date on which the Effective Time occurs is herein
referred to as the "CLOSING DATE."

                  1.6 CONVERSION OF COMMON SHARES. At the Effective Time, by
virtue of the Merger and without any action on the part of Purchaser, the
Company or the holder of any of the securities specified below:

                  (a) Each Common Share issued and outstanding immediately
before the Effective Time (other than any Dissenting Shares (as hereinafter
defined) and Common Shares to be canceled pursuant to SECTION 1.6(b)) shall be
canceled and extinguished and be converted into the right to receive the Per
Share Amount in cash payable to the holder thereof, without interest, upon
surrender of the certificate representing such Common Share in accordance with
SECTION 1.8 hereof. From and after the Effective Time, the holders of
certificates evidencing ownership of Common Shares outstanding immediately prior
to the Effective Time shall cease to have any rights with respect to such Common
Shares except as otherwise provided for herein or by applicable Law (as defined
below).

                                      -11-


<PAGE>


                  (b) Each Common Share owned by Guarantor, Parent, Purchaser or
any direct or indirect wholly owned subsidiary of Guarantor immediately before
the Effective Time shall be canceled and extinguished, and no payment or other
consideration shall be made with respect thereto.

                  (c) The shares of Purchaser common stock outstanding
immediately prior to the Merger shall be converted into 1,000 shares of the
common stock of the Surviving Corporation (the "SURVIVING CORPORATION COMMON
STOCK"), which shares of the Surviving Corporation Common Stock shall constitute
all of the issued and outstanding capital stock of the Surviving Corporation and
shall be owned by Parent.

                  1.7 DISSENTING SHARES. (a) Notwithstanding any provision of
this Agreement to the contrary, any Common Shares issued and outstanding
immediately prior to the Effective Time and held by a holder who has demanded
and perfected his demand for appraisal of his Common Shares in accordance with
the Oregon Code (including but not limited to Sections 60.561 - 60.581 thereof),
and as of the Effective Time has neither effectively withdrawn nor lost his
right to such appraisal ("DISSENTING SHARES"), shall not be converted into or
represent a right to receive cash pursuant to SECTION 1.6 hereof, but the holder
thereof shall be entitled to only such rights as are granted by the Oregon Code.

                  (b) Notwithstanding the provisions of SECTION 1.7(a) hereof,
if any holder of Common Shares who demands appraisal of his Common Shares under
the Oregon Code shall effectively withdraw or lose (through failure to perfect
or otherwise) his right to appraisal, then as of the Effective Time or the
occurrence of such event, whichever occurs later, such holder's Common Shares
shall automatically be converted into and represent only the right to receive
cash as provided in SECTION 1.6 hereof, without interest thereon, upon surrender
of the certificate or certificates representing such Common Shares.

                  (c) The Company shall give Purchaser (i) prompt notice of any
written demands for appraisal or payment of the fair value of any Common Shares,
withdrawals of such demands and any other instruments served pursuant to the
Oregon Code received by the Company after the date hereof and (ii) the
opportunity to direct all negotiations and proceedings with respect to demands
for appraisal under the Oregon Code. The Company shall not voluntarily make any
payment with respect to any demands for appraisal and shall not, except with the
prior written consent of Purchaser, settle or offer to settle any such demands.

                  1.8 SURRENDER OF COMMON SHARES. (a) Prior to the Effective
Time, Purchaser shall appoint ChaseMellon Shareholder Services, L.L.C. or such
other commercial bank or trust company designated by Purchaser and reasonably
acceptable to the Company to act as exchange agent hereunder (the "EXCHANGE
AGENT") for the payment of the Per Share Amount upon surrender of certificates
representing the Common Shares. All of the fees and


                                      -12-


<PAGE>


expenses of the Exchange Agent shall be borne by Purchaser.

                  (b) Parent shall cause the Surviving Corporation to provide
the Exchange Agent with cash in amounts necessary to pay for all of the Common
Shares pursuant to SECTION 1.8(c) hereof when and as such amounts are needed by
the Exchange Agent.

                  (c) On the Closing Date, Purchaser shall instruct the Exchange
Agent to mail to each holder of record of a certificate representing any Common
Shares canceled upon the Merger pursuant to SECTIONS 1.6(a) hereof, within five
business days of receiving from the Company a list of such holders of record,
(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
delivery of the certificates to the Exchange Agent and shall be in such form and
have such other provisions as Parent may reasonably specify) and (ii)
instructions for use in effecting the surrender of the certificates. Each holder
of a certificate or certificates representing any Common Shares canceled upon
the Merger pursuant to SECTIONS 1.6(a) hereof may thereafter surrender such
certificate or certificates to the Exchange Agent, as agent for such holder, to
effect the surrender of such certificate or certificates on such holder's behalf
for a period ending one year after the Effective Time. Upon the surrender of
certificates representing the Common Shares, Parent shall cause the Exchange
Agent to pay the holder of such certificates in exchange therefor cash in an
amount equal to the Per Share Amount multiplied by the number of Common Shares
represented by such certificate. Until so surrendered, each such certificate
(other than certificates representing Dissenting Shares) shall represent solely
the right to receive the aggregate Per Share Amount relating thereto.

                  (d) If payment of cash in respect of canceled Common Shares is
to be made to a person other than the person in whose name a surrendered
certificate or instrument is registered, it shall be a condition to such payment
that the certificate or instrument so surrendered shall be properly endorsed or
shall be otherwise in proper form for transfer and that the person requesting
such payment shall have paid any transfer and other taxes required by reason of
such payment in a name other than that of the registered holder of the
certificate or instrument surrendered or shall have established to the
satisfaction of Parent or the Exchange Agent that such tax either has been paid
or is not payable.

                  (e) At the Effective Time, the stock transfer books of the
Company shall be closed, and no transfer of Common Shares shall be made
thereafter, other than transfers of Common Shares that have occurred prior to
the Effective Time. In the event that, after the Effective Time, certificates
are presented to the Surviving Corporation, they shall be canceled and exchanged
for cash as provided in SECTIONS 1.6(a).

                  (f) The Per Share Amount paid in the Merger shall be net to
the holder of Common Shares in cash, and without interest thereon subject to
reduction only for any applicable withholding or stock transfer taxes payable by
such holder.

                                      -13-


<PAGE>


                  (g) Promptly following the date which is one year after the
Effective Time, the Exchange Agent shall deliver to Parent all cash,
certificates and other documents in its possession relating to the transactions
contemplated hereby, and the Exchange Agent's duties shall terminate.
Thereafter, each holder of a certificate representing Common Shares (other than
certificates representing Dissenting Shares and certificates representing Common
Shares held directly or indirectly by Purchaser, Parent or Guarantor) may
surrender such certificate to the Surviving Corporation and (subject to any
applicable abandoned property, escheat or similar law) receive in consideration
therefor the aggregate Per Share Amount relating thereto, without any interest
thereon.

                  (h) None of the Company, Parent, Purchaser, Guarantor, the
Surviving Corporation or the Exchange Agent shall be liable to any holder of
Common Shares for any cash delivered to a public official pursuant to any
abandoned property, escheat or similar law, rule, regulation, statute, order,
judgment or decree.

                  1.9 OPTIONS, WARRANTS AND EMPLOYEE STOCK PURCHASE PLAN. (a)
Each option outstanding immediately prior to the Effective Time to purchase
Common Shares (a "COMPANY OPTION") under the Company's 1995 Stock Incentive Plan
or any other stock option plan or agreement of the Company, whether or not then
vested or exercisable, shall constitute the right to receive an amount in cash
equal to the positive difference, if any, between the Per Share Amount and the
exercise price of the Company Option multiplied by the number of Common Shares
for which the Company Option was exercisable immediately prior to the Effective
Time, subject to reduction only for any applicable withholding taxes. The
Company shall provide a period of at least 30 days prior to the Effective Time
during which Company Options may be exercised to the extent exercisable at the
Effective Time and, upon the expiration of such period, all unexercised Company
Options shall immediately terminate. The Company may, in its sole discretion,
permit holders of Company Options that are not exercisable before the Effective
Time to exchange such options for cash as described in the first sentence of
this Section 1.9(a). In lieu of exercising Company Options as described in this
Section 1.9(a), the holders shall be given the right, and the Company shall
encourage the holders of Company Options to exercise such right, to exchange
such options for cash as described in the first sentence of this Section 1.9(a).
In no event will any Company Options be exercisable after the Effective Time,
except to receive cash as provided in the first sentence of this Section 1.9(a).

                  (b) Each of the warrants of the Company, dated November 17,
1995, to purchase Common Shares at a price of $12.00 per share, subject to
adjustment (the "COMPANY WARRANTS"), shall be exercisable, from and after the
Effective Time, for an amount of cash equal to the Per Share Amount multiplied
by the number of Common Shares for which such warrant was exercisable
immediately prior to the Effective Time. Except as aforesaid, the exercise of
any Company Warrant shall remain subject to all terms and conditions provided in
the applicable Company Warrant and/or Warrant Agreement. Each of the Company and
Parent shall take all action necessary to provide that, upon consummation

                                      -14-


<PAGE>


of the Merger, all Company Warrants outstanding immediately prior to the
Effective Time shall be exercisable for a cash amount as aforesaid.

                  (c) The Company shall take such action as is necessary to
cause the ending date of the then current offering period under the Company's
employee stock purchase plan (the "COMPANY STOCK PURCHASE PLAN") to be prior to
the Effective Time and to terminate such plan as of the Effective Time.

                  1.10 ARTICLES OF INCORPORATION AND BYLAWS. Subject to SECTION
5.5 hereof, unless otherwise determined by Parent prior to the Effective Time,
at and after the Effective Time (a) the Second Amended and Restated Articles of
Incorporation of the Company, as in effect immediately prior to the Effective
Time, shall be the Articles of Incorporation of the Surviving Corporation until
thereafter amended as provided by the Oregon Code and such Articles of
Incorporation; PROVIDED, HOWEVER, that (i) Article II shall be amended and
restated in its entirety to provide that the capital stock of the Surviving
Corporation shall consist solely of 1,000 shares of common stock; and (b) the
Bylaws of the Surviving Corporation shall be the Bylaws of Purchaser in effect
at the Effective Time (subject to any subsequent amendments).

                  1.11 DIRECTORS AND OFFICERS. At and after the Effective Time,
the directors of Purchaser immediately prior to the Effective Time shall be the
initial directors of the Surviving Corporation, and the officers of the Company
immediately prior to the Effective Time shall be the initial officers of the
Surviving Corporation, in each case until their successors are duly elected or
appointed and qualified.

                  1.12 OTHER EFFECTS OF MERGER. The Merger shall have all
further effects as specified in the applicable provisions of the Oregon Code.

                  1.13 PROXY STATEMENT. (a) Following the consummation of the
Offer and if required by the Securities Exchange Act because of action by the
Company's shareholders necessary in order to consummate the Merger, the Company
shall prepare and file with the SEC and, when cleared by the SEC, shall mail to
shareholders, a proxy statement in connection with a meeting of the Company's
shareholders to vote upon the adoption of this Agreement and the Merger and the
transactions contemplated hereby and thereby (the "COMPANY PROPOSALS"), or an
information statement, as appropriate, satisfying all requirements of the
Securities Exchange Act (such proxy or information statement in the form mailed
by the Company to its shareholders, together with any and all amendments or
supplements thereto, is herein referred to as the "PROXY STATEMENT").

                  (b) Parent will furnish the Company with such information
concerning Parent and its subsidiaries as is necessary in order to cause the
Proxy Statement, insofar as it relates to Parent and its subsidiaries, to comply
with applicable Law. Parent agrees promptly to advise the Company if, at any
time prior to the meeting of shareholders of the Company

                                      -15-


<PAGE>


referenced herein, any Parent Information (as defined below) in the Proxy
Statement is or becomes incorrect or incomplete in any material respect and to
provide the Company with the information needed to correct such inaccuracy or
omission. Parent will furnish the Company with such supplemental information as
may be necessary in order to cause the Proxy Statement, insofar as it relates to
Guarantor and its subsidiaries, to comply with applicable Law after the mailing
thereof to the shareholders of the Company.

                  (c) The Company and Parent agree to cooperate in making any
preliminary filings of the Proxy Statement with the SEC, as promptly as
practicable, pursuant to Rule 14a-6 or Rule 14c-5, as applicable, under the
Securities Exchange Act.

                  (d) The Company shall provide Parent for its review a copy of
the Proxy Statement prior to each filing thereof, with reasonable time and
opportunity for such review. Parent authorizes the Company to utilize in the
Proxy Statement the information concerning Parent and its subsidiaries provided
to the Company in connection with, or contained in, the Proxy Statement.

                  1.14 ADDITIONAL ACTIONS. If, at any time after the Effective
Time, the Surviving Corporation shall consider or be advised that any deeds,
bills of sale, assignments, assurances or any other actions or things are
necessary or desirable to vest, perfect or confirm of record or otherwise in the
Surviving Corporation its right, title or interest in, to or under any of the
rights, properties or assets of Purchaser or the Company or otherwise to carry

shall be authorized to execute and deliver, in the name and on behalf of
Purchaser or the Company, all such deeds, bills of sale, assignments and

Company, all such other actions and things as may be necessary or desirable to
vest, perfect or confirm any and all right, title and interest in, to and under
such rights, properties or assets in the Surviving Corporation or otherwise to
carry out this Agreement.

                  1.15 MERGER WITHOUT MEETING OF SHAREHOLDERS. Notwithstanding
the foregoing provisions of this ARTICLE I, in the event that Purchaser, or any
other direct or indirect subsidiary of Parent, shall acquire at least 90 percent
of the outstanding Common Shares, the parties hereto agree to take all necessary
and appropriate action to cause the Merger to become effective as soon as
practicable after the expiration of the Offer without a meeting of shareholders
of the Company, in accordance with Section 60.491 of the Oregon Code.

                  1.16 LOST, STOLEN OR DESTROYED CERTIFICATES. In the event any
certificates representing shares of Common Shares shall have been lost, stolen
or destroyed, the Exchange Agent shall make such payment in exchange for such
lost, stolen or destroyed certificates upon the making of an affidavit of that
fact by the holder thereof; PROVIDED, HOWEVER, that Parent may, in its
discretion and as a condition precedent to the issuance

                                      -16-


<PAGE>


thereof, require the owner of such lost, stolen or destroyed certificates to
deliver a bond in such sum as it may reasonably direct as indemnity against any
claim that may be made against Parent or the Exchange Agent with respect to the
certificates alleged to have been lost, stolen or destroyed.

                  1.17 MATERIAL ADVERSE EFFECT. (a) When used in connection with
the Company or any Company Subsidiaries (as defined below) or Parent, Guarantor
or any of their respective subsidiaries, as the case may be, the term "MATERIAL
ADVERSE EFFECT" means any change, effect or circumstance that, individually or
when taken together with all other similar changes, effects or circumstances
that have occurred during the period relevant to the determination of such
Material Adverse Effect, is or is reasonably likely to be materially adverse to

results of operations of the Company and any Company Subsidiaries or Parent,
Guarantor and their respective subsidiaries, as the case may be, in each case
taken as a whole; PROVIDED, HOWEVER, that effects of changes that are applicable

conditions generally, (B) the United States securities markets, (C) this
Agreement or the transactions contemplated by this Agreement and (D) the effect
of the public announcement of the transactions contemplated hereby, including

materially and adversely affects the ability of the Company or Parent, as the

validly executed and delivered by Guarantor, and constitutes the legal, valid
and binding agreement of Guarantor enforceable against Guarantor in accordance

                  3.4 NO VIOLATIONS. The execution and delivery of this
Agreement, the consummation of the transactions contemplated hereby and
compliance by Parent or Purchaser with any of the provisions hereof will not (i)
conflict with or result in any breach of any provision of the Memorandum of
Association and Bye-Laws or other governing instruments of Guarantor or similar
documents of any subsidiary of Guarantor, including Parent and Purchaser, (ii)
require any Consent under or result in a violation or breach of, or constitute
(with or without notice or lapse of time or both) a default (or give rise to any
right of termination, cancellation or acceleration) under any of the terms,
conditions or provisions of, any material note, bond, mortgage, indenture,
contract, lease, license, agreement or instrument to which Guarantor or any
subsidiary of Guarantor, including Parent, is a party or by which any of them or
any of their respective assets or property is subject, (iii) result in the
creation or imposition of any material lien or encumbrance of any kind upon any

Guarantor, including Parent, or its assets or properties are subject, except in
any such case for any such conflicts, violations, breaches, defaults or other
occurrences that would not prevent or delay consummation of the Offer or the
Merger, or otherwise materially and adversely affect the ability of Parent or
Purchaser to perform their respective obligations under this Agreement.

                  3.5 DISCLOSURE DOCUMENTS. None of the information supplied by
Parent, or Purchaser or their respective officers, directors, representatives,
agents or employees (the "PARENT INFORMATION") for inclusion in the Proxy
Statement will, at the time the Proxy Statement is filed with the SEC or first
mailed to the Company's shareholders, at the time of the Company's shareholders'
meeting, contain any untrue statement of a material fact, or will omit to state
any material fact necessary in order to make the statements therein, in light of
the circumstances in which they were made not misleading or necessary to correct
any statement in any earlier communication with respect to the solicitation of
proxies for such shareholders' meeting which has become false or misleading.
Neither the Schedule 14D-1 or the Offer Documents or any amendments thereof or
supplements thereto nor any of the Parent Information provided specifically for
inclusion in the Schedule 14D-9 will, at the respective times the Schedule
14D-1, the Offer Documents or the Schedule 14D-9 are filed with the SEC or first
published, sent or given to the Company's shareholders, contain any untrue
statement of a material fact or omit to state any material fact necessary in
order to make the statements therein, in light of the circumstances under which
they were made, not misleading. Notwithstanding the foregoing, neither Parent
nor Purchaser makes any representation or warranty with respect to any
information that has been supplied by the Company or its accountants, counsel or
other authorized representatives for use in any of the foregoing documents. The
Schedule 14D-1 and the Offer Documents will comply as to form in all material
respects with the provisions of the Securities Exchange Act.

                  3.6 FINDERS AND INVESTMENT BANKERS. Neither Parent, Guarantor,
Purchaser nor any of their respective officers or directors has employed any
broker, finder or financial



                                      -36-

advisor or otherwise incurred any liability for any brokerage fees, commissions
or financial advisors' or finders' fees in connection with the transactions
contemplated hereby.

                  3.7 FINANCING ARRANGEMENTS. Parent (including for this purpose
one or more other subsidiaries of Guarantor ), has funds available to it
sufficient to enable the Purchaser to purchase the Common Shares in accordance
with the terms of this Agreement and to pay all amounts due (or which will, as a
result of the transactions contemplated hereby, become due) in respect of any
indebtedness of the Company for money borrowed.

                  3.8 NO PRIOR ACTIVITIES. Except for obligations or liabilities
incurred in connection with its incorporation or organization or the negotiation
and consummation of this Agreement and the transactions contemplated hereby
(including any financing in connection therewith), Purchaser has not incurred
any obligations or liabilities and has not engaged in any business or activities
of any type or kind whatsoever or entered into any agreements or arrangements

<PAGE>

reasonably be expected to result in a Material Adverse Effect.

                  4.3 ACCESS AND INFORMATION. Between the date of this Agreement
and the Effective Time, and without intending by this SECTION 4.3 to limit any
of the other obligations of the parties under this Agreement, the Company will
give, and shall direct its accountants and legal counsel to give, Parent and its
authorized representatives (including, without limitation, its financial
advisors, accountants and legal counsel), at reasonable times and without undue
disruption to or interference with the normal conduct of the business and
affairs of the Company, access as reasonably required in connection with the
transactions provided for in this Agreement to all offices and other facilities

                  4.5 REASONABLE BEST EFFORTS. Subject to the terms and
conditions herein provided, the Company agrees to use reasonable best efforts to
take, or cause to be taken, all actions and to do, or cause to be done, all
things necessary, proper or advisable to consummate and make effective as
promptly as practicable the transactions contemplated by this Agreement,
including, but not limited to, (i) obtaining all Consents from Governmental
Authorities and other third parties required for the consummation of the Offer
and the Merger and the transactions contemplated thereby and (ii) timely making
all necessary filings under the HSR Act. Upon the terms and subject to the
conditions hereof, the Company agrees to use reasonable best efforts to take, or
cause to be taken, all actions and to do, or cause to be done, all things
necessary to satisfy the other conditions of the Closing set forth herein.

                  4.6 PUBLIC ANNOUNCEMENTS. So long as this Agreement is in
effect, the Company shall not, and shall use reasonable best efforts to cause
its affiliates not to, issue or cause the publication of any press release or
any other announcement with respect to the Offer or the Merger or the
transactions contemplated hereby without the consent of Parent (such consent not
to be unreasonably withheld or delayed), except where such release or
announcement is required by applicable Law or pursuant to any applicable listing
agreement with, or rules or regulations of, the NASD or NASDAQ, in which case
the Company, prior to making such announcement, will consult with Parent
regarding the same.

                  4.7 COMPLIANCE. In consummating the transactions contemplated
hereby, the Company shall comply in all material respects with the provisions of
the Securities Exchange Act and the Securities Act and shall comply, and cause
the Company Subsidiaries to comply or to be in compliance, in all material
respects, with, all other applicable Laws.

                  4.8 NO SOLICITATION. (a) The Company shall not, directly or
indirectly, through any officer, director, employee, representative or agent of
the Company or any of the Company Subsidiaries, solicit or encourage the
initiation of (including by way of furnishing information) any inquiries or
proposals regarding any merger, sale of assets, sale of shares of capital stock
(including without limitation by way of a tender offer) or similar transactions
involving the Company or any Company Subsidiaries that if consummated would
constitute an Alternative Transaction (as defined below) (any of the foregoing
inquiries or proposals being referred to herein as a "COMPANY TAKEOVER
PROPOSAL"). Nothing contained in this Agreement shall prevent the Board of
Directors of the Company from (i) furnishing information to a third party which
has made a BONA FIDE Company Takeover Proposal that is a Superior Proposal (as
defined below) not solicited in violation of this Agreement, provided that such
third party has executed an agreement with confidentiality provisions
substantially similar to those then in effect between the Company and an
affiliate of Parent (the "CONFIDENTIALITY AGREEMENT") or (ii) subject to
compliance with the other terms of this SECTION 4.8, considering and negotiating
a bona fide Company Takeover Proposal that is a Superior Proposal not solicited
in violation of this Agreement; provided that, as to each of clauses (i) and
(ii), the Board of Directors of the Company reasonably determines in good faith
(after



                                      -41-
<PAGE>

due consultation with independent counsel, which may be Stoel Rives LLP) that it
is or is reasonably likely to be required to do so in order to discharge
properly its fiduciary duties. For purposes of this Agreement, a "SUPERIOR
PROPOSAL" means any proposal made by a party to acquire, directly or indirectly,
for consideration consisting of cash and/or securities, all of the equity
securities of the Company entitled to vote generally in the election of
directors or all the assets of the Company (other than a de minimus amount of
assets not material to the conduct of the Company's business), on terms which
the Board of Directors of the Company reasonably believes (after due
consultation with a financial advisor of nationally recognized reputation, which
may be the Financial Advisor or McDonald Investments) to be more favorable from
a financial point of view to its shareholders than the Offer and the Merger
taking into account at the time of determination all factors relating to such
proposed transaction deemed relevant by the Board of Directors of the Company,
including, without limitation, the financing thereof, the proposed timing
thereof and all other conditions thereto and any changes to the financial terms
of this Agreement proposed by Parent and Purchaser. "ALTERNATIVE TRANSACTION"
means any of (i) a transaction pursuant to which any person (or group of
persons) other than Parent or its affiliates (a "THIRD PARTY") acquires or would
acquire more than 20% of the outstanding shares of any class of equity
securities of the Company, whether from the Company or pursuant to a tender
offer or exchange offer or otherwise, (ii) a merger or other business
combination involving the Company pursuant to which any Third Party acquires
more than 20% of the outstanding equity securities of the Company or the entity
surviving such merger or business combination, (iii) any transaction pursuant to
which any Third Party acquires or would acquire control of assets (including for
this purpose the outstanding equity securities of Company Subsidiaries and
securities of the entity surviving any merger or business combination including
any of the Company Subsidiaries) of the Company or any Company Subsidiaries
having a fair market value (as determined by the Board of Directors of the
Company in good faith) equal to more than 20% of the fair market value of all
the assets of the Company and the Company Subsidiaries, taken as a whole,
immediately prior to such transaction, or (iv) any other consolidation, business
combination, recapitalization or similar transaction involving the Company or
any of the Company Subsidiaries, other than the transactions contemplated by
this Agreement; PROVIDED, HOWEVER, that the term Alternative Transaction shall
not include any acquisition of securities by a broker dealer in connection with
a BONA FIDE public offering of such securities. Notwithstanding anything to the
contrary contained in this SECTION 4.8 or elsewhere in this Agreement, prior to
the Effective Time, the Company may, in connection with a possible Company
Takeover Proposal, refer any third party to this SECTION 4.8 and SECTION 8.7 and
make a copy of this SECTION 4.8 and SECTION 8.7 available to a third party.

                  (b) The Company shall immediately notify Parent and Purchaser
after receipt of any Company Takeover Proposal, or any modification of or
amendment to any Company Takeover Proposal, or any request for nonpublic
information relating to the Company or any of the Company Subsidiaries in
connection with a Company Takeover Proposal or for access to the properties,
books or records of the Company or any subsidiary by any person or entity that
informs the Board of Directors of the Company or such subsidiary that it is
considering



                                      -42-
<PAGE>

making, or has made, a Company Takeover Proposal. Such notice to Parent and
Purchaser shall be made orally and in writing, and shall indicate the identity
of the person making the Company Takeover Proposal or intending to make the
Company Takeover Proposal or requesting non-public information or access to the
books and records of the Company, the terms of any such Company Takeover
Proposal or modification or amendment to a Company Takeover Proposal, and
whether the Company is providing or intends to provide the person making the
Company Takeover Proposal with access to information concerning the Company as
provided in SECTION 4.8(a). The Company shall also immediately notify Parent and
Purchaser, orally and in writing, if it enters into negotiations concerning any
Company Takeover Proposal.

                  (c) Except as set forth in this SECTION 4.8, neither the Board
of Directors of the Company nor any committee thereof shall (i) withdraw or
modify, or indicate publicly its intention to withdraw or modify, in a manner
adverse to Parent, the approval or recommendation by such Board of Directors or
such committee of the Offer or the Company Proposals, (ii) approve or recommend,
or indicate publicly its intention to approve or recommend, any Company Takeover
Proposal or (iii) cause the Company to enter into any letter of intent,
agreement in principle, acquisition agreement or other similar agreement (each,
a "COMPANY ACQUISITION AGREEMENT") related to any Company Takeover Proposal.
Notwithstanding the foregoing, in the event that prior to the Effective Time the
Board of Directors of the Company determines in good faith, after due
consultation with outside counsel, that the failure to do so constitutes or is
reasonably likely to constitute a breach of its fiduciary duties to the
Company's shareholders under applicable law, the Board of Directors of the
Company may (subject to this and the following sentences) approve or recommend a
Superior Proposal and, in connection therewith, withdraw or modify its approval
or recommendation of the Offer or the Company Proposals, but only at a time that
is after the third business day following Parent's receipt of written notice
advising Parent that the Board of Directors of the Company has received a
Superior Proposal and, in the case of any previously received Superior Proposal
that has been materially modified or amended, such modification or amendment and
specifying the material terms and conditions of such Superior Proposal,
modification or amendment.

                  (d) Nothing contained in this SECTION 4.8 shall prohibit the
Company from taking and disclosing to its shareholders a position contemplated
by Rule 14e-2(a) promulgated under the Securities Exchange Act or from making
any disclosure to the Company's shareholders if, in the good faith judgment of
the Board of Directors of the Company, with the advice of outside counsel,
failure so to disclose could be determined to be a breach of its fiduciary
duties to the Company's shareholders under applicable law; PROVIDED, HOWEVER,
that neither the Company nor its Board of Directors nor any committee thereof
shall, except as permitted by SECTION 4.8(c), withdraw or modify, or indicate
publicly its intention to withdraw or modify, its position with respect to the
Offer or the Company Proposals or approve or recommend, or indicate publicly its
intention to approve or recommend, a Company Takeover Proposal.

                  (e) The Company shall advise its officers and directors and
any investment banker or attorney retained by the Company in connection with the
transactions contemplated by this Agreement of the restrictions set forth in
this SECTION 4.8.

                  4.9 SEC AND SHAREHOLDER FILINGS. The Company shall send to
Parent a copy of all material public reports and materials as and when it sends
the same to its shareholders, the SEC or any state or foreign securities
commission.

                  4.10 TAKEOVER STATUTES. If any "fair price," "moratorium,"
"control share acquisition" or other similar anti-takeover statute or regulation
enacted under state or federal laws in the United States (each a "TAKEOVER
STATUTE"), including, without limitation, Sections 60.825 - 60.845 of the Oregon
Code, is or may become applicable to the Offer or the Merger, the Company will
use reasonable best efforts to grant such approvals and take such actions as are
necessary so that the transactions contemplated by this Agreement and the
Company Proposals may be consummated as promptly as practicable on the terms
contemplated hereby and otherwise act so as to eliminate or minimize the effects
of any Takeover Statute on any of the transactions contemplated hereby.

                  4.11 COMPANY OPTIONS AND STOCK PURCHASE PLAN. (a) Prior to the
consummation of the Offer, the Company shall take all action necessary in order
to effectuate the provisions of Section 1.9(a) relating to Company Options.

                  (b) The Company will not accelerate the exercisability of any
Company Option that by its terms is not exercisable prior to March 1, 2000.

                  5.2 PUBLIC ANNOUNCEMENTS. So long as this Agreement is in
effect, Parent and Purchaser shall not, and shall use reasonable best efforts to
cause their affiliates not to, issue or cause the publication of any press
release or any other announcement with respect to the Offer or the Merger or the
transactions contemplated hereby without the consent of the Company (such
consent not to be unreasonably withheld or delayed), except where such release
or announcement is required by applicable Law or pursuant to any applicable
listing agreement with, or rules or regulations of, any stock exchange on which
shares of Guarantor's capital stock are listed or the NASD, or other applicable
securities exchange, in which case Parent, prior to making such announcement,
will consult with the Company regarding the same.

                  5.3 COMPLIANCE. In consummating the transactions contemplated
hereby, Parent and Purchaser shall comply in all material respects with the
provisions of the Securities Exchange Act and the Securities Act and shall
comply, and cause their subsidiaries to comply or to be in compliance, in all
material respects, with all other applicable Laws.

                  5.4 EMPLOYEE BENEFIT PLANS. (a) As of the Effective Time,
Parent shall cause the Surviving Corporation to honor and satisfy all
obligations and liabilities with respect to the Employee Plans. Notwithstanding
the foregoing, the Surviving Corporation shall not be required to continue any
particular Employee Plan after the Effective Time, and any Employee Plan may be
amended or terminated in accordance with its terms and applicable Law. To the
extent that any Employee Plan is terminated or amended after the Effective Date
so as to eliminate the future benefits that are being provided with respect to
participants thereunder, Parent shall arrange for each individual who is then a
participant in such terminated or amended plan to participate in a Parent
Benefit Plan ("PARENT BENEFIT PLAN"), to the extent similarly situated employees
of the Parent participate in such Parent Benefit Plan, in accordance with the
eligibility criteria thereof, provided that (i) such participant shall receive
full credit for years of service with the Company or any of the Company
Subsidiaries prior to the Effective Time for all purposes for which such service
was recognized under the applicable Employee Plan, including, but not limited
to, recognition of service for eligibility, vesting (including acceleration
thereof pursuant to the terms of the applicable Employee Plan), entitlement to
commence benefits and, to the extent not duplicative of benefits received under
such Employee Plan, the amount of benefits, (ii) Parent shall cause any and all
pre-existing condition limitations (to the extent such limitations did not apply
to a pre-existing condition under the Employee Plans) and eligibility waiting
periods under any group health plans to be waived with respect to such
participant and his or her eligible dependents and (iii) Parent shall cause the
Parent Benefit Plans that are group welfare plans to provide such participant
with credit towards any applicable deductibles, co-payments and similar
exclusions for expenses incurred prior to the Effective Time.

                  (b) The provisions of this SECTION 5.4 are not intended to and
do not create rights of third party beneficiaries.

                  5.5 INDEMNIFICATION. (a) From and after the Effective Time,
the Surviving Corporation shall indemnify and hold harmless all past and present
officers and directors (the "INDEMNIFIED PARTIES") of the Company and of the
Company Subsidiaries to the full extent such persons may be indemnified by the
Company pursuant to Oregon law, the Company's Second Amended and Restated
Articles of Incorporation and Bylaws, as each is in effect on the date of this
Agreement, for acts and omissions (x) arising out of or pertaining to the
transactions contemplated by this Agreement or arising out of the Offer
Documents or (y) otherwise with respect to any acts or omissions occurring or
arising at or prior to the Effective Time and shall advance reasonable
litigation expenses incurred by such persons in connection with defending any
action arising out of such acts or omissions, PROVIDED that such persons provide
the requisite affirmations and undertaking, as set forth in Section 60.397 of
the Oregon Code.

                  (b) In addition, Parent will provide, or cause the Surviving
Corporation to provide, for a period of not less than six years after the
Effective Time, the Company's current directors and officers an insurance and
indemnification policy that provides coverage for events occurring or arising at
or prior to the Effective Time (the "D&O INSURANCE") that is no less favorable
than the existing policy or, if substantially equivalent insurance coverage is
unavailable, the best available coverage; PROVIDED, HOWEVER, that Parent and the
Surviving Corporation shall not be required to pay an annual premium for the D&O
Insurance in excess of 200% of the annual premium currently paid by the Company
for such insurance, but in such case shall purchase as much such coverage as
possible for such amount.

                  (c) This SECTION 5.5 is intended to benefit the Indemnified
Parties and shall be binding on all successors and assigns of Parent, Purchaser,
the Company and the Surviving Corporation. Parent hereby guarantees the
performance by the Surviving Corporation of the indemnified obligations pursuant
to this SECTION 5.5, which guaranty is absolute and unconditional and shall not
be affected by any circumstance whatsoever, including the bankruptcy or
insolvency of the Surviving Corporation or any other person. The Indemnified
Parties shall be intended third-party beneficiaries of this SECTION 5.5.

                  5.6 VOTING OF COMMON SHARES. At any meeting of the Company's
shareholders held for the purpose of voting upon the Company Proposals, all of
the Common Shares then owned by Parent, Purchaser or any other subsidiaries of
Parent shall be voted in favor of the Company Proposals.

                  5.7 GUARANTEE OF PARENT. Parent hereby guarantees the payment
by Purchaser of the Per Share Amount and any other amounts payable by Purchaser
pursuant to this Agreement and will cause Purchaser to perform all of its other
obligations under this Agreement in accordance with their terms.

shall be subject to the fulfillment or waiver at or prior to the Effective Time
of the following conditions:

                  6.1 OFFER. The Offer shall have been consummated; PROVIDED

accept for payment or pay for Common Shares pursuant to the Offer in violation
of the terms of the Offer or of this Agreement.

                  6.2 SHAREHOLDER APPROVAL. If required, the Company Proposals

of the foregoing vacated, dismissed or withdrawn by the Effective Time.

                  6.4 GOVERNMENTAL APPROVALS. All Consents of any Governmental
Authority required for the consummation of the Merger and the transactions
contemplated by this Agreement shall have been obtained, except for those
Consents the failure to obtain which will not have a material adverse effect on
the business, assets, condition (financial or other), liabilities or results of
operations of the Surviving Corporation and its subsidiaries taken as a whole.

                                   ARTICLE VII

                  (a) by mutual written consent of Parent and the Company;

                  (b) by either Parent or the Company if any Governmental
         Authority shall have issued an order, decree or ruling or taken any
         other action permanently enjoining, restraining or otherwise
         prohibiting the consummation of the transactions contemplated by this
         Agreement and such order, decree or ruling or other action shall have
         become final and nonappealable;

                  (c) by Parent if:

<PAGE>

                  (i) the Company shall have breached or failed to perform in
         any material respect any of its covenants or other agreements contained
         in this Agreement, which breach or failure to perform is incapable of
         being cured or has not been cured within five (5) days after the giving
         of written notice thereof to the Company (but not later than the
         expiration of the twenty (20) business day period provided for the
         Offer under SECTION 1.1(b) hereof);

                  (ii) any representation or warranty of the Company shall not
         have been true and correct when made (without for this purpose giving
         effect to qualifications of materiality contained in such
         representation and warranty), if such failure to be true and correct,
         individually or in the aggregate, would reasonably be expected to have
         a Material Adverse Effect;

                  (iii) any representation or warranty of the Company shall
         cease to be true and correct at any later date (without for this
         purpose giving effect to qualifications of materiality contained in
         such representation and warranty) as if made on such date (other than
         representations and warranties made as of a specified date) other than
         as a result of a breach or failure to perform by the Company of any of
         its covenants or agreements under this Agreement if such failure to be
         true and correct, individually or in the aggregate, would reasonably be
         expected to have a Material Adverse Effect; PROVIDED, HOWEVER, that
         such representation or warranty is incapable of being cured or has not
         been cured within five (5) days after the giving of written notice
         thereof to the Company (but not later than the expiration of the twenty
         (20) business day period provided for the Offer under SECTION 1.1(b)
         hereof); PROVIDED, HOWEVER, that the right to terminate this Agreement
         pursuant to this SECTION 7.1(c) shall not be available to Parent if
         Purchaser or any other affiliate of Parent shall acquire shares of
         Common Shares pursuant to the Offer;

                  (d) by Parent if, whether or not permitted to do so by this
         Agreement, (i) the Board of Directors of the Company or any committee
         thereof shall have withdrawn or modified in a manner adverse to Parent
         or Purchaser its approval or recommendation of the Offer or any of the
         Company Proposals; (ii) the Board of Directors of the Company or any
         committee thereof shall have approved or recommended to the

         Directors of the Company or any committee thereof shall have taken any

         foregoing; (v) the Board of Directors of the Company or any committee
         thereof shall have resolved to take any of the foregoing actions;

<PAGE>

                  (e) by either Parent or the Company if, as the result of the
         failure of the Minimum Condition or any of the other conditions set
         forth in Annex I hereto, the Offer shall have terminated or expired in
         accordance with its terms without Purchaser having purchased any Common
         Shares pursuant to the Offer, PROVIDED that if the failure to satisfy
         any conditions set forth in Annex I shall be a basis for termination of
         this Agreement under any other clause of this Section 7.1, a
         termination pursuant to this clause (e) shall be deemed a termination
         under such other clause;

                  (f) by either Parent or the Company if the Offer shall not
         have been consummated on or before February 29, 2000, PROVIDED that the
         right to terminate this Agreement pursuant to this SECTION 7.1(f) shall
         not be available to any party whose failure to perform any of its
         obligations under this Agreement results in the failure of the Offer to
         be consummated by such time;

                  (g) by the Company, if Parent or Purchaser shall have breached
         or failed to perform in any material respect any of its
         representations, warranties, covenants or other agreements contained in
         this Agreement, which breach or failure to perform is incapable of
         being cured or has not been cured within five (5) days after the giving
         of written notice thereof to Parent; or

                  (h) by the Company, in order to accept a Superior Proposal,
         PROVIDED that the Board of Directors of the Company reasonably
         determines in good faith (after due consultation with independent
         counsel, which may be Stoel Rives LLP), that it is or is reasonably
         likely to be required to accept such proposal in order to discharge
         properly its fiduciary duties; the Company has given parent three
         business days' advance notice of the Company's intention to accept such
         Superior Proposal; the Company shall in fact accept such proposal; the
         Company shall have paid the fee and expenses contemplated by SECTION
         8.7 hereof; and the Company shall have complied in all respects with
         the provisions of Section 4.8.

The party desiring to terminate this Agreement pursuant to the preceding
paragraphs shall give written notice of such termination to the other party in
accordance with SECTION 8.5 hereof.

                  7.2 EFFECT OF TERMINATION AND ABANDONMENT. In the event of
termination of this Agreement and the abandonment of the Offer or the Merger
pursuant to this ARTICLE VII, this Agreement (other than SECTIONS 7.2, 8.1, 8.3,
8.5, 8.6, 8.7, 8.8, 8.10, 8.11, 8.12, 8.14 and 8.15 hereof) shall become void
and of no effect with no liability on the part of any party hereto (or of any of
its directors, officers, employees, agents, legal or financial advisors or other
representatives); PROVIDED, HOWEVER, that no such termination shall relieve any
party hereto from any liability for any willful breach of this Agreement prior
to termination. If this Agreement is terminated as provided herein, each party
shall use all reasonable best efforts to



                                      -49-

redeliver all documents, work papers and other material (including any copies
thereof) of any other party relating to the transactions contemplated hereby,
whether obtained before or after the execution hereof, to the party furnishing
the same.


                                  ARTICLE VIII
MISCELLANEOUS

                  8.1 CONFIDENTIALITY. (a) Unless (i) otherwise expressly
provided in this Agreement, (ii) required by applicable Law or any listing
agreement with, or the rules and regulations of, the NASDAQ or any other
applicable securities exchange or the NASD, (iii) necessary to secure any
required Consents as to which the other party has been advised or (iv) consented
to in writing by Parent and the Company, all information (whether oral or
written) and documents furnished in connection herewith together with analyses,
compilations, studies or other documents prepared by such party which contain or
otherwise reflect such information shall be kept strictly confidential by the
Company, Parent, Purchaser and their respective officers, directors, employees
and agents. Prior to any disclosure permitted pursuant to the preceding
sentence, the party intending to make such disclosure shall consult with the
other party regarding the nature and extent of the disclosure. Nothing contained
herein shall preclude disclosures to the extent necessary to comply with
accounting, SEC and other disclosure obligations imposed by applicable Law. In
the event the transactions contemplated by this Agreement are not consummated,
each party shall return to the other any documents furnished by the other and
all copies thereof that any of them may have made and will hold in confidence
any information obtained from the other party except to the extent (a) such
party is required to disclose such information by Law or such disclosure is
necessary or desirable in connection with the pursuit or defense of a claim, (b)
such information was known by such party prior to such disclosure (and PROVIDED
that, except with respect to information referred to in the following clause
(c), such party shall have advised the other party of such knowledge upon or
promptly after its receipt of such information) or was thereafter developed or
obtained by such party independent of such disclosure or (c) such information is
or becomes generally available to the public other than by breach of this
SECTION 8.1 (or, to such party's knowledge, breach of a confidentiality
agreement with the other party). Prior to any disclosure of information pursuant
to the exception in clause (a) of the preceding sentence, the party intending to
disclose the same shall so notify the party which provided the same in order
that such party may seek a protective order or other appropriate remedy should
it choose to do so.

                  (b) The Parent and the Company further acknowledge that
certain of the business and activities of each of them is competitive with
business and activities of the other party, and each of them therefore agrees
that it will not use, or seek to obtain any competitive or other business
advantage as a result of, the information or documents so received by it in
connection herewith, such party acknowledging that such use would be unfair and
materially detrimental to the other party, PROVIDED that the provisions of this
SECTION 8.1(b) shall not apply to information referred to in clause (c) of
SECTION 8.1(a) hereof.

modified or supplemented only by a written agreement among the Company, Parent
and Purchaser.

                  8.3 WAIVER OF COMPLIANCE; CONSENTS. Any failure of the Company
on the one hand, or Parent and Purchaser on the other hand, to comply with any
obligation, covenant, agreement or condition herein may be waived by Parent on
the one hand, or the Company on the other hand, only by a written instrument
signed by the party granting such waiver, but such waiver or failure to insist
upon strict compliance with such obligation, covenant, agreement or condition
shall not operate as a waiver of, or estoppel with respect to, any subsequent or
other failure. Whenever this Agreement requires or permits consent by or on
behalf of any party hereto, such consent shall be given in writing in a manner
consistent with the requirements for a waiver of compliance as set forth in this
SECTION 8.3.

                  8.4 SURVIVAL. The respective representations, warranties,
covenants and agreements of the Company and Parent contained herein or in any

investigation made or information obtained by the other party, but shall
terminate at the Effective Time, except for those contained in SECTIONS 1.7,
1.8, 1.9, 1.14, 5.4, 5.5, 5.7 and 8.8 hereof and this SECTION 8.4, which shall

attached hereto and the Company Disclosure Letter referred to herein, which
Annex(es) and Company Disclosure Letter are incorporated herein by reference,

or regulations) may delay the acceptance for payment of any tendered Common
Shares and (except as provided in this Agreement) amend or terminate the Offer

the following conditions exists:

                  (a) there shall be in effect an injunction or other order,

prohibits or restricts the ownership or operation by Parent (or any of its
affiliates or subsidiaries) of any portion of the Company's business or assets,

taken as a whole or which would substantially deprive Parent and/or its
affiliates or subsidiaries of the benefit of ownership of the Company's business
or assets, or compels Parent (or any of its affiliates or subsidiaries) to
dispose of or hold separate any portion of the Company's business or assets, or
Guarantor's business or assets relating to the printed circuit board business,
which is material to the printed circuit board business of all such entities
taken as a whole or which would substantially deprive Parent and/or its

                                      A-1
<PAGE>

without limitation, by requiring the prior consent of any person or entity
(including any Governmental Authority) to future transactions by Guarantor (or
any of its affiliates); or

                  (b) there shall have been instituted, pending or threatened an
action by a Governmental Authority seeking to restrain or prohibit the making or
consummation of the Offer, the consummation of the Merger or to impose any other
restriction, prohibition or limitation referred to in the foregoing paragraph
(a); or

                  (c) this Agreement shall have been terminated by the Company
or Parent in accordance with its terms; or

                  (d) there shall have occurred (i) any general suspension of,
or limitation on prices for, trading in the Common Shares on NASDAQ, (ii) a
declaration of a banking moratorium or any general suspension of payments in
respect of banks in the United States or (iii) in the case of any of the
foregoing existing at the time of the execution of this Agreement, a material
acceleration or worsening thereof; or

                  (e) Parent and the Company shall have agreed that Purchaser
shall amend the Offer to terminate the Offer or postpone the payment for Common

or shall thereafter have ceased to be true and correct as if made as of such
later date (other than representations and warranties made as of a specified
date) (in each case without for this purpose giving effect to qualifications of
materiality contained in such representation and warranty), or the Company shall
not have performed each obligation and agreement and complied with each covenant
to be performed and complied with by it under this Agreement, if such failure to
be true and correct or such failure to perform, individually or in the
aggregate, would reasonably be expected to have a Material Adverse Effect,
PROVIDED, however, that such breach or failure to perform is incapable of being
cured or has not been cured within 5 days after the giving of written notice
thereof to the Company, PROVIDED, however, that no such 5-day cure period shall
require extension of the Offer beyond the twenty (20) business days provided
under SECTION 1.1(b) of the Agreement; or

                  (g) the Company's Board of Directors shall have modified or
amended its recommendation of the Offer in any manner adverse to Parent or shall
have withdrawn its recommendation of the Offer, or shall have recommended
acceptance of any Company Takeover Proposal or shall have resolved to do any of
the foregoing; or

                  (h) (i) any corporation, entity or "group" (as defined in
Section 13(d)(3) of the Securities Exchange Act) ("PERSON/GROUP"), other than
Parent and Purchaser and any person/group identified in the Company's Proxy
Statement dated October 25, 1999), shall



                                     A-2
<PAGE>

have acquired beneficial ownership of more than 15% of the outstanding Common
Shares, or shall have been granted any options or rights, conditional or
otherwise, to acquire a total of more than 15% of the outstanding Common Shares
and which, in each case, does not tender the Common Shares beneficially owned by
it in the Offer; (ii) any new group shall have been formed which beneficially
owns more than 15% of the outstanding Common Shares and which does not tender
the Common Shares beneficially owned by it in the Offer; or (iii) any
person/group (other than Parent or one or more of its affiliates) shall have
entered into an agreement in principle or definitive agreement with the Company
with respect to a tender or exchange offer for any Common Shares or a merger,
consolidation or other business combination with or involving the Company; or

                  (i) any change, development, effect or circumstance shall have
occurred or be threatened that would reasonably be expected to have a Material
Adverse Effect with respect to the Company; or

                  (j) the Company shall commence a case under any chapter of
Title XI of the United States Code or any similar law or regulation; or a
petition under any chapter of Title XI of the United States Code or any similar
law or regulation is filed against the Company which is not dismissed within 2
business days.

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

                  Should the Offer be terminated pursuant to the foregoing
provisions, all tendered Common Shares not theretofore accepted for payment
shall forthwith be returned to the tendering shareholders.

                                                                Exhibit 99(c)(3)


                             SHAREHOLDER'S AGREEMENT


         THIS SHAREHOLDER'S AGREEMENT is made and entered into as of this 26th
day of October 1999, among SIGMA CIRCUITS, INC., Inc., a Delaware corporation
("PARENT"), T MERGER SUB (OR), INC., an Oregon corporation and a wholly owned
subsidiary of Parent ("PURCHASER"), and ROBERT L. PRAEGITZER (the
"SHAREHOLDER").

         WHEREAS the Shareholder desires that PRAEGITZER INDUSTRIES INC., Inc.,
an Oregon corporation (the "COMPANY"), Parent and Purchaser enter into an
Agreement and Plan of Merger dated as of the date hereof (as the same may be
amended or supplemented, the "MERGER AGREEMENT") with respect to the merger of
Purchaser with and into the Company (the "MERGER"); and

         WHEREAS the Shareholder is executing this Agreement as an inducement to
Parent to enter into and execute, and to cause Purchaser to enter into and
execute, the Merger Agreement.

         NOW, THEREFORE, in consideration of the execution and delivery by
Parent and Purchaser of the Merger Agreement and the mutual covenants,
conditions and agreements contained herein and therein, the parties agree as
follows:

         SECTION 1. REPRESENTATIONS AND WARRANTIES. The Shareholder represents
and warrants to Parent and Purchaser as follows:

                  (a) The Shareholder is the record and beneficial owner of the
number of shares of Common Stock of the Company (the "COMPANY COMMON STOCK"),
separately identified as such, set forth opposite the Shareholder's name in
SCHEDULE A hereto (as may be adjusted from time to time pursuant to Section 5,
the Shareholder's "SHARES"). Except for the Shareholder's Shares and any other
shares of Company Common Stock subject hereto, the Shareholder is not the record
or beneficial owner of any shares of Company Common Stock.

                  (b) This Agreement has been duly authorized, executed and
delivered by the Shareholder and constitutes the legal, valid and binding
obligation of the Shareholder, enforceable against the Shareholder in accordance
with its terms, except as limited by applicable bankruptcy, insolvency,
reorganization, moratorium and other laws of general application affecting
enforcement of creditors' rights generally. Neither the execution and delivery
of this Agreement nor the consummation by the Shareholder of the transactions
contemplated hereby will result in a violation of, or a default under, or
conflict with, any contract, trust, commitment, agreement, understanding,
arrangement or restriction of any kind to which the Shareholder is a party or
bound or to which the Shareholder's Shares are subject. To the best of the
Shareholder's knowledge, consummation by the Shareholder of the


                                       1
<PAGE>

transactions contemplated hereby will not violate, or require any consent,
approval, or notice under, any provision of any judgment, order, decree,
statute, law, rule or regulation applicable to the Shareholder or the
Shareholder's Shares.

                  (c) The Shareholder's Shares and the certificates representing
such Shares are now and at all times during the term hereof will be held by the
Shareholder, or by a nominee or custodian for the benefit of the Shareholder,
free and clear of all liens, claims, security interests, proxies, voting trusts
or agreements, understandings or arrangements or any other encumbrances
whatsoever, except for any such encumbrances or proxies arising hereunder or as
listed on Annex I annexed hereto.

                  (d) Except for fees payable to Adams, Harkness & Hill, Inc.
and McDonald Investments, Inc., no broker, investment banker, financial adviser
or other person is entitled to any broker's, finder's, financial adviser's or
other similar fee or commission from Parent, Purchaser or the Company in
connection with the transactions contemplated hereby based upon arrangements
made by or on behalf of the Shareholder.

                  (e) The Shareholder understands and acknowledges that Parent
is entering into, and causing Purchaser to enter into, the Merger Agreement in
reliance upon the Shareholder's execution and delivery of this Agreement. The
Shareholder acknowledges that the irrevocable proxy set forth in Section 4 is
granted in consideration for the execution and delivery of the Merger Agreement
by Parent and Purchaser.

         SECTION 2. AGREEMENT TO TENDER OR SELL. (a) The Shareholder hereby
agrees that it shall tender his Shares into the Offer (as defined in the Merger
Agreement) and that it shall not withdraw any Shares so tendered (it being
understood that the obligation contained in this sentence is unconditional);
PROVIDED, HOWEVER, that if the Shareholder is unable to tender any Shares that
are pledged to KeyBank National Association ("KEYBANK"), as set forth on
Annex I, the Shareholder shall not be obligated to tender such Shares; PROVIDED
FURTHER that the Shareholder shall sell such Shares to Purchaser, and Purchaser
shall purchase such Shares from Shareholder at the Per Share Amount prior to the
Effective Time promptly upon termination of the pledge agreements between the
Shareholder and KeyBank relating to such Shares. Purchaser hereby agrees that,
if the Offer is consummated, it will satisfy the liabilities secured by the
pledge of Shares to KeyBank prior to the Effective Time.

         (b) The Shareholder shall tender his Shares (other than the Shares
pledged to KeyBank) not later than fourteen business days following commencement
of the Offer, other than with respect to the Shares subject to the CBL Insured
Credit Facility Agreement (the "CBL AGREEMENT") referred to on Annex I which
shall be tendered not later than one business day prior to the initially
scheduled expiration of the Offer; PROVIDED, HOWEVER, that if the Shares subject
to the CBL Agreement are not tendered as aforesaid, any damages of Purchaser
shall be limited to $5,000,000.

                                       2
<PAGE>


          SECTION 3. COVENANTS. The Shareholder agrees with, and covenants to,
Parent and Purchaser as follows:

                  (a) The Shareholder shall not, except as contemplated by the
terms of this Agreement, (i) transfer (the term "TRANSFER" shall include,
without limitation, for the purposes of this Agreement, any sale, gift, pledge
or other disposition), or consent to any transfer of, any or all of the
Shareholder's Shares or any interest therein, (ii) enter into any contract,
option or other agreement or understanding with respect to any transfer of any
or all of such Shares or any interest therein, (iii) grant any proxy,
power-of-attorney or other authorization or consent in or with respect to such
Shares except with respect to election of directors at the Company's annual
meeting, (iv) deposit such Shares into a voting trust or enter into a voting
agreement or arrangement with respect to such Shares or (v) take any other
action that would in any way restrict, limit or interfere with the performance
of its obligations hereunder or the transactions contemplated hereby.

                  (b) Subject to Section 8, the Shareholder shall not, nor shall
it permit any investment banker, attorney or other adviser or representative of
the Shareholder to, directly or indirectly, (i) solicit, initiate or encourage
the submission of, any Acquisition Proposal (as defined in the Merger Agreement)
or (ii) 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 Acquisition Proposal. Without limiting
the foregoing, it is understood that any violation of the restrictions set forth
in the preceding sentence by an investment banker, attorney or other adviser or
representative of the Shareholder, whether or not such person is purporting to
act on behalf of the Shareholder or otherwise, shall be deemed to be a violation
of this Section 3(b) by the Shareholder.

         SECTION 4.  GRANT OF IRREVOCABLE PROXY; APPOINTMENT OF PROXY.

                  (a) Subject to the provisions of the pledge agreements with
Keybank, the Shareholder hereby irrevocably grants to, and appoints, Parent and
Mark A. Belnick, and any other individual who shall hereafter be designated by
Parent, the Shareholder's proxy and attorney-in-fact (with full power of
substitution), for and in the name, place and stead of the Shareholder, to vote
the Shareholder's Shares, or grant a consent or approval in respect of such
Shares, at any meeting of shareholders of the Company or at any adjournment
thereof or in any other circumstances upon which their vote, consent or other
approval is sought, against (i) any merger agreement or merger (other than the
Merger Agreement and the Merger), consolidation, combination, sale of
substantial assets, reorganization, joint venture, recapitalization,
dissolution, liquidation or winding up of or by the Company and (ii) any
amendment of the Company's Articles of Incorporation or By-laws or other
proposal or transaction (including any consent solicitation to remove or elect
any directors of the Company) involving the Company or any of its subsidiaries
which amendment or other proposal or transaction would in any manner impede,
frustrate, prevent or nullify, or result in


                                       3
<PAGE>

a breach of any covenant, representation or warranty or any other obligation or
agreement of the Company under or with respect to, the Offer, the Merger, the
Merger Agreement or any of the other transactions contemplated by the Merger
Agreement (each of the foregoing in clause (i) or (ii) above, a "COMPETING
TRANSACTION").

                  (b) Subject to the provisions of the pledge agreements with
KeyBank, the Shareholder represents that any proxies heretofore given in respect
of the Shareholder's Shares are not irrevocable, and that any such proxies are
hereby revoked.

                  (c) The Shareholder hereby affirms that the irrevocable proxy
set forth in this Section 4 is given in connection with the execution of the
Merger Agreement, and that such irrevocable proxy is given to secure the
performance of the duties of the Shareholder under this Agreement. The
Shareholder hereby further affirms that the irrevocable proxy is coupled with an
interest and may under no circumstances be revoked. The Shareholder hereby
ratifies and confirms all that such irrevocable proxy may lawfully do or cause
to be done by virtue hereof. Such irrevocable proxy is executed and intended to
be irrevocable in accordance with the provisions of Section 60.231 of the Oregon
Business Corporation Act (the "CORPORATION LAW").

         SECTION 5. CERTAIN EVENTS. The Shareholder agrees that this Agreement
and the obligations hereunder shall attach to the Shareholder's Shares and shall
be binding upon any person or entity to which legal or beneficial ownership of
such Shares shall pass, whether by operation of law or otherwise, including
without limitation the Shareholder's heirs, guardians, administrators or
successors. In the event of any stock split, stock dividend, merger,
reorganization, recapitalization or other change in the capital structure of the
Company affecting the Company Common Stock, or the acquisition of additional
shares of Company Common Stock or other securities or rights of the Company by
any Shareholder, the number of Shares listed on Schedule A beside the name of
the Shareholder shall be adjusted appropriately and this Agreement and the
obligations hereunder shall attach to any additional shares of Company Common
Stock or other securities or rights of the Company issued to or acquired by the
Shareholder.

         SECTION 6. STOP TRANSFER. The Company agrees with, and covenants to,
Parent that the Company shall not register the transfer of any certificate
representing any Shareholder's Shares, unless such transfer is made to Parent or
Purchaser or otherwise in compliance with this Agreement.

         SECTION 7. VOIDABILITY. If prior to the execution hereof, the Board of
Directors of the Company shall not have duly and validly authorized and approved
by all necessary corporate action the acquisition of Company Common Stock by
Parent and Purchaser and the other transactions contemplated by this Agreement
and the Merger Agreement, so that by the execution and delivery hereof Parent or
Purchaser would become, or could reasonably be expected to become, an
"Interested shareholder" with whom the Company would be


                                       4
<PAGE>

prevented for any period pursuant to Section 60.825 - 60.845 of the Corporation
Law from engaging in any "Affiliated transaction" (as such terms are defined in
Section 60.825 of the Corporation Law) then this Agreement shall be void and
unenforceable until such time as such authorization and approval shall have been
duly and validly obtained.

         SECTION 8. SHAREHOLDER CAPACITY. The Shareholder does not make any
agreement or understanding in his capacity as director or officer of the
Company. The Shareholder signs solely in his capacity as the record holder and
beneficial owner of Shareholder's Shares and nothing herein shall limit or
affect any actions taken by the Shareholder in his capacity as an officer or
director of the Company to the extent specifically permitted by the Merger
Agreement.

         SECTION 9. FURTHER ASSURANCES. The Shareholder shall, upon request of
Parent or Purchaser execute and deliver any additional documents and take such
further actions as may reasonably be deemed by Parent or Purchaser to be
necessary or desirable to carry out the provisions hereof and to vest the power
to vote the Shareholder's Shares as contemplated by Section 4 in Parent and the
other irrevocable proxies described therein.

         SECTION 10. TERMINATION. This Agreement, and all rights and obligations
of the parties hereunder, shall terminate upon the earlier of (a) the date upon
which the Merger Agreement is terminated in accordance with its terms or (b) the
date that Parent or Purchaser shall have purchased and paid for the Shares of
the Shareholder pursuant to Section 2; PROVIDED, HOWEVER, that the termination
of this Agreement shall not relieve any party of liability for breach of this
Agreement prior to termination.

         SECTION 11. PUBLIC ANNOUNCEMENTS. The Shareholder will consult with
Parent before issuing, and provide Parent with the opportunity to review and
comment upon, any press release or other public statements with respect to the
transactions contemplated by this Agreement and the Merger Agreement, and shall
not issue any such press release or make any such public statement prior to such
consultation, except as may be required by applicable law, court process or by
obligations pursuant to any listing agreement with any national securities
exchange.

         SECTION 12. MISCELLANEOUS.

                  (a) Capitalized terms used and not otherwise defined in this
Agreement shall have the respective meanings assigned to such terms in the
Merger Agreement.

                  (b) All notices, requests, claims, demands and other
communications under this Agreement shall be in writing and shall be deemed
given if delivered personally or sent by overnight courier (providing proof of
delivery) to the parties at the following addresses (or at such other address
for a party as shall be specified by like notice): (i) if to Parent or
Purchaser, to the address set forth in Section 8.5 of the Merger Agreement; and
(ii) if to a


                                       5
<PAGE>

Shareholder, to the address set forth on Schedule A hereto, or such other
address as may be specified in writing by the Shareholder.

                  (c) The headings contained in this Agreement are for reference
purposes only and shall not affect in any way the meaning or interpretation of
this Agreement.

                  (d) This Agreement may be executed in two or more
counterparts, all of which shall be considered one and the same agreement, and
shall become effective when one or more counterparts have been signed by each of
Parent, Purchaser and the Shareholder and delivered to Parent, Purchaser and the
Shareholder.

                  (e) This Agreement (including the documents and instruments
referred to herein) constitutes the entire agreement, and supersedes all prior
agreements and understandings, both written and oral, among the parties with
respect to the subject matter hereof.

                  (f) This Agreement shall be governed by, and construed in
accordance with, the laws of the New York and, to the extent expressly provided
herein, the Corporation Law, regardless of the laws that might otherwise govern
under applicable principles of conflicts of laws thereof.

                  (g) Neither this Agreement nor any of the rights, interests or
obligations under this Agreement shall be assigned, in whole or in part, by
operation of law or otherwise, by any of the parties without the prior written
consent of the other parties, except by laws of descent. Any assignment in
violation of the foregoing shall be void.

                  (h) If any term, provision, covenant or restriction herein, or
the application thereof to any circumstance, shall, to any event, be held by a
court of competent jurisdiction to be invalid, void or unenforceable, the
remainder of the terms, provisions, covenants and restrictions herein and the
application thereof to any other circumstances, shall remain in full force and
effect, shall not in any way be affected, impaired or invalidated, and shall be
enforced to the fullest extent permitted by law.

                  (i) The Shareholder agrees that irreparable damage would occur
and that Parent and Purchaser would not have any adequate remedy at law in the
event that any of the provisions of this Agreement were not performed in
accordance with their specific terms or were otherwise breached. It is
accordingly agreed that Parent and Purchaser shall be entitled to an injunction
or injunctions to prevent breaches by any Shareholder of this Agreement and to
enforce specifically the terms and provisions of this Agreement. Each of the
parties hereto (i) consents to submit such party to the personal jurisdiction of
any Federal court located in the State of New York in the event any dispute
arises out of this Agreement or any of the transactions contemplated hereby, and
(ii) agrees that such party will not attempt to deny or defeat such personal
jurisdiction by motion or other request for leave from any such court.

                  (j) No amendment, modification or waiver in respect of this
Agreement shall be effective against any party unless it shall be in writing and
signed by such party.
