an Ohio corporation ("Procter & Gamble") and Tenzing, Inc., a Minnesota
corporation and a direct wholly owned subsidiary of Procter & Gamble ("Merger

the Offer (as defined below) and the transactions contemplated thereby. The
principal business offices of each of Procter and Gamble and Merger Sub are

anticipated that, prior to the consummation of the Offer and the Merger (as
defined below), Merger Sub will have any significant assets or liabilities or
will engage in any activities other than those incident to the Offer and the
Merger.

              (d)-(e) During the five years prior to the date hereof, none of
the Procter & Gamble Companies nor, to the best of their knowledge, any
executive officer or director of any of the Procter & Gamble Companies (who are
listed on Schedule I to the Offer to Purchase filed as part of the Schedule
14D-1 (as defined below)), (i) has been convicted in criminal proceeding
(excluding traffic violations or similar misdemeanors) or (ii) has been a party
to a civil proceeding of a judicial or administrative body of competent
jurisdiction, as a result of which such person was or is subject to a judgment,
decree or final order enjoining future violations of, or prohibiting or
mandating activities subject to, federal or state securities laws or finding any

$283 million. Amounts necessary to pay for the shares of Issuer Common Stock
which are tendered in the Offer will be obtained by Merger Sub from Procter &
Gamble's existing working capital.

ITEM 4.  Purpose of Transaction
         ----------------------

                                      -6-
<PAGE>

              Procter & Gamble, Merger Sub, and the Issuer entered into an
Agreement and Plan of Merger (the "Merger Agreement") dated as of August 26,
1999 providing for, among other things, the commencement by Merger Sub of a
tender offer to purchase all of the outstanding shares of Issuer Common Stock
for $35.25 per share in cash without interest (the "Offer") and, following the
Offer, the merger of the Issuer and Merger Sub (the "Merger"). Simultaneously
with the execution and delivery of the Merger Agreement, the Procter & Gamble
Companies entered into a Tender and Option Agreement dated as of August 26, 1999
(the "Tender and Option Agreement") with certain shareholders of the Issuer (the
"Major Shareholders") as follows: (i) WEC, Inc. (formerly known as Wanner
Engineering, Inc.) - 596,100 shares; (ii) William F. Wanner, Jr. - 58,050 shares
and 8,000 options exercisable within 60 days; and (iii) Brian F. Sullivan -
408,500 shares and 121,500 options exercisable within 60 days. Under the Tender
and Option Agreement, the Major Shareholders have agreed, subject to the terms
thereof, to tender all of their shares of Issuer Common Stock to Merger Sub
pursuant to the Offer. The Major Shareholders have also granted the Procter &
Gamble Companies a proxy to vote their shares, representing approximately 19.3%
of the issued and outstanding shares of Issuer Common Stock as of August 25,
1999, in favor of the Merger. The Major Shareholders have also granted the
Procter & Gamble Companies an option to purchase their shares of Issuer Common
Stock under certain conditions.

              Simultaneously with the execution and delivery of the Merger
Agreement, Procter & Gamble also entered into a Stock Option Agreement (the
"Company Option") pursuant to which the Issuer granted to Procter & Gamble an
option to purchase 1,202,875 shares of Issuer Common Stock, subject to the terms
thereof. The Procter & Gamble Companies disclaim beneficial ownership of these
shares of Issuer Common Stock.

              The foregoing summary of the Tender and Option Agreement and
Company Option is qualified in its entirety by reference to such agreements,
which have been filed as exhibits to this Schedule 13D.

              Except as indicated in this Schedule 13D or as disclosed in the
Schedule 14D-1 of the Procter & Gamble Companies filed with the Securities and
Exchange Commission on September 1, 1999 (the "Schedule 14D-1"), the contents of
which are incorporated herein by reference, the Procter & Gamble Companies
currently have no specific plans or proposals that relate to or would result in
any of the matters described in subparagraphs (a) through (j) of Item 4 of
Schedule 13D.

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

Agreement, the Procter & Gamble Companies may be deemed to own beneficially

13D, are not the "beneficial owner" of any such shares, as such term is defined
in the Securities Exchange Act of 1934 or the rules and regulations thereunder.

                  (b) Pursuant to the Tender and Option Agreement, the Procter &
Gamble Companies possess shared power to vote, or direct the vote of, the shares
of the Issuer Common Stock held by the Major Shareholders.

                  (c) Except as set forth herein, none of the Procter & Gamble
Companies beneficially owns any shares of Issuer Common Stock and none of the
Procter & Gamble Companies, or any executive officer or director of any of the
Procter & Gamble Companies (who are listed on Schedule I to the Offer to
Purchase filed as part of the Schedule 14D-1), has engaged in any transaction in
any such shares during the sixty day period immediately preceding the date
hereof except as described herein.

none of the Procter & Gamble Companies or any executive officer or director of
any of the Procter & Gamble Companies (who are listed on Schedule I to the Offer
to Purchase filed as part of the Schedule 14D-1) has any other contracts,
arrangements, understandings or relationships with any persons with respect to
any securities of the Issuer. The transactions discussed in Item 4 are further
described in the Schedule 14D-1 and in the exhibits to the Schedule 14D-1,
including the Merger Agreement, the Tender and Option Agreement, the Company

<PAGE>

ARTICLE I
THE OFFER

     SECTION  1.1.  The Offer.

          (a)  The Offer.  Subject to the provisions of this Agreement and this
Agreement not having been terminated, as promptly as practicable but in no event
later than September 1, 1999, Merger Sub shall, and the Parent shall cause
Merger Sub to, commence, within the meaning of Rule 14d-2 under the Securities
Exchange Act of 1934, as amended, and the rules and regulations promulgated
thereunder (the "Exchange Act"), an offer to purchase all of the outstanding
shares of common stock, par value $.01 per share (the "Company Common Stock"),
of the Company, together with the associated Rights, at a price equal to $35.25
per share of Company Common Stock (the "Merger Consideration"), net to the
seller in cash (the "Offer"). Except where the context otherwise requires, all
references herein to the shares of Company Common Stock shall include the
associated Rights. The obligation of Merger Sub to, and of the Parent to cause
Merger Sub to, commence the Offer and to accept for payment, and pay for, any
shares of Company Common Stock tendered pursuant to the Offer shall be subject
to the conditions set forth in Exhibit A and to the other terms and conditions
of this Agreement. Subject to the provisions of this Agreement, the Offer shall
expire 20 business days after the date of its commencement, unless this
Agreement is terminated in accordance with Article IX, in which case the Offer
(whether or not previously extended in accordance with the terms hereof) shall
expire on such date of termination.

          (b)   Waiver.  Without the prior written consent of the Company,
Merger Sub shall not (i) waive the Minimum Condition (as defined in Exhibit A),
(ii) reduce the number of shares of Company Common Stock subject to the Offer,
(iii) reduce the Merger Consideration, (iv) extend the Offer if all of the Offer
conditions are satisfied or waived, (v) change the form of consideration payable
in the Offer, or (vi) amend or modify any term or condition of the Offer
(including the conditions set forth in Exhibit A) in any manner adverse to the
holders of Company Common Stock. Notwithstanding anything herein to the
contrary, Merger Sub may, in its reasonable discretion 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 Merger
Sub's obligation to accept for payment and pay for shares of Company Common
Stock shall not have been 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; (iii) for any
period required by applicable Laws in connection with an increase in the
consideration to be paid pursuant to the Offer; and (iv) if all Offer conditions
are satisfied or waived but the number of shares of Company Common Stock
tendered is 80% or more, but less than 90%, of the then outstanding number of
shares of Company Common Stock, for an aggregate period of not more than 10
business days (for all such extensions under this clause (iv)) beyond the latest
expiration date that would be permitted under clause (i), (ii) or (iii) of this
sentence. In addition, if any condition set forth in Exhibit A is not satisfied
at the scheduled expiration of the Offer but is reasonably capable of being
satisfied within three business days thereof, Merger Sub shall, and Parent shall
cause Merger Sub to, extend the Offer for three business days and the Parent and
the Company shall each use reasonable efforts to cause such condition to become
satisfied during such three business day period. Subject to the terms and
<PAGE>

conditions of the Offer and this Agreement (including the right of termination
in accordance with Article IX), Merger Sub shall, and the Parent shall cause
Merger Sub to, accept for payment and pay for, in accordance with the terms of
the Offer, all shares of Company Common Stock validly tendered and not withdrawn
pursuant to the Offer as soon as practicable after the expiration of the Offer
but in no event later than two business days after expiration of the Offer.
Notwithstanding the immediately preceding sentence and subject to the applicable
rules of the SEC and the terms and conditions of the Offer, Merger Sub expressly
reserves the right to delay payment for shares of Company Common Stock in order
to comply in whole or in part with applicable Laws. Any such delay shall be
effected in compliance with Rule 14e-1(c) under the Exchange Act.


  SECTION 1.2.  Actions by the Parent and Merger Sub.

          (a)  Offer Documents.  As soon as reasonably practicable following
execution of this Agreement, but in no event later than five business days from
the date hereof, the Parent and Merger Sub shall prepare and file with the SEC a
Tender Offer Statement on Schedule 14D-1 with respect to the Offer, which shall
contain an offer to purchase and a related letter of transmittal and any other
ancillary documents pursuant to which the Offer shall be made (such Schedule
14D-1 and the documents therein pursuant to which the Offer will be made,
together with any supplements or amendments thereto, the "Offer Documents").
The Company and its counsel shall be given an opportunity to review and
comment upon the Offer Documents (and shall provide any comments thereon as
soon as practicable) prior to the filing thereof with the SEC. The Offer
Documents shall comply as to form in all material respects with the requirements
of the Exchange Act, and on the date filed with the SEC and on the date first
published, sent or given to the Company's shareholders, the Offer Documents
shall not contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading, except that no representation is made by the Parent or Merger
Sub with respect to information supplied by the Company for inclusion in the
Offer Documents. Each of the Parent, Merger Sub and the Company agrees promptly
to correct any information provided by it for use in the Offer Documents if and
to the extent that such information shall have become false or misleading in any
material respect, and each of the Parent, Merger Sub and the Company further
agrees to take all steps necessary to cause the Offer Documents as so corrected
to be filed with the SEC and to be disseminated to holders of shares of Company
Common Stock, in each case as and to the extent required by applicable federal
securities laws. The Parent and Merger Sub agree to provide the Company and its
counsel in writing with any comments the Parent, Merger Sub or their counsel may
receive from the SEC or its staff with respect to the Offer Documents promptly
after receipt of such comments and with copies of any written responses and
telephonic notification of any verbal responses by the Parent, Merger Sub or
their counsel.

          (b)  Funds.  The Parent shall provide or cause to be provided to
Merger Sub all of the funds necessary to purchase any shares of Company Common
Stock that Merger Sub becomes obligated to purchase pursuant to the Offer.

     SECTION 1.3  Actions by the Company.

<PAGE>

          (a)  Company Approvals. The Company hereby approves of and consents to
the Offer and represents and warrants that the Board of Directors of the Company
(the "Board of Directors" or the "Board") at a meeting duly called and held has
duly adopted resolutions (i) approving this Agreement, the Option Agreement, the
Ancillary Documents, the Offer and the Merger, determining that the Merger is
advisable and that the terms of the Offer and the Merger are fair to, and in the
best interests of, the Company and the Company's shareholders and recommending
that the Company's shareholders accept the Offer and approve the Merger and this
Agreement, and (ii) taking all action necessary so that Sections 302A.671,
302A.673 and 302A.675 of the Minnesota Business Corporation Act (the "MBCA"),
and the Rights Agreement, dated as of January 30, 1996, between the Company and
Norwest Bank Minnesota, N.A., as Rights Agent, as amended (the "Rights
Agreement"), are and, through the Effective Time, will be inapplicable to the
Parent and Merger Sub, the Offer, the Merger, this Agreement, the Option
Agreement, the Tender and Option Agreement, any of the Ancillary Documents or
any of the transactions contemplated hereby or thereby. The Company further
represents and warrants that the Board of Directors has received the written
opinion of Goldman, Sachs & Co. (the "Financial Advisor") that the proposed
consideration to be received by the holders of shares of Company Common Stock
pursuant to the Offer and the Merger is fair to such holders from a financial
point of view (the "Fairness Opinion"). The Company hereby consents to the
inclusion in the Offer Documents of the recommendation of the Board of Directors
described in the first sentence of this Section 1.3(a). The Company hereby
represents and warrants that it has been authorized by the Financial Advisor to
permit the inclusion of the Fairness Opinion and references thereto, subject to
prior review and consent by the Financial Advisor (such consent not to be
unreasonably withheld), in the Offer Documents, the Schedule 14D-9 and the Proxy
Statement. The Company has been advised by its directors and executive officers
that they intend to tender into the Offer all shares of Company Common Stock
beneficially owned by them on the date hereof.

          (b)  Schedule 14D-9.  On the date the Offer Documents are filed with
the SEC, the Company shall file with the SEC a Solicitation/Recommendation
Statement on Schedule 14D-9 with respect to the Offer (such Schedule 14D-9, as
amended from time to time, the "Schedule 14D-9") containing the recommendations
described in Section 1.3(a) and shall disseminate the Schedule 14D-9 to the
shareholders of the Company as required by Rule 14d-9 promulgated under the
Exchange Act. To the extent practicable, the Company shall cooperate with Merger
Sub and/or the Parent in mailing or otherwise disseminating the Schedule 14D-9
with the appropriate Offer Documents to the Company's shareholders. The Parent
and its counsel shall be given an opportunity to review and comment upon the
Schedule 14D-9 (and shall provide any comments thereon as soon as practicable)
prior to the filing thereof with the SEC. The Schedule 14D-9 shall comply as to
form in all material respects with the requirements of the Exchange Act and, on
the date filed with the SEC and on the date first published, sent or given to
the Company's shareholders, shall not contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary in order to make the statements therein, in light of the circumstances
under which they were made, not misleading, except that no representation is
made by the Company with respect to information supplied by the Parent or Merger
Sub for inclusion in the Schedule 14D-9. Each of the Company, the Parent and
Merger Sub agrees promptly to correct any information provided by it for use in
the Schedule 14D-9 if and to the extent that such information shall have become
false or misleading in any
<PAGE>

material respect, and the Company further agrees to take all steps necessary to
cause the Schedule 14D-9 as so corrected to be filed with the SEC and to be
disseminated to the holders of shares of Company Common Stock, in each case as
and to the extent required by applicable federal securities laws. The Company
agrees to provide the Parent and Merger Sub and their counsel in writing with
any comments the Company or its counsel may receive from the SEC or its staff
with respect to the Schedule 14D-9 promptly after the receipt of such comments
and with copies of any written response and telephonic notification of any
verbal responses by the Company or its counsel.

          (c)  Mailing.  In connection with the Offer, the Company shall cause
its transfer agent to furnish Merger Sub with mailing labels containing the
names and addresses of the record holders of Company Common Stock as of a recent
date and thereafter, until expiration of the Offer, of those persons becoming
record holders subsequent to such recent date, together with copies of all lists
of shareholders, security position listings and computer files and all other
information in the Company's possession or control regarding the beneficial
owners of Company Common Stock, and shall furnish to Merger Sub such information
and assistance (including updated lists of shareholders, security position
listings and computer files) as Merger Sub may reasonably request in
communicating the Offer to the Company's shareholders. Subject to the
requirements of applicable Laws, and except for such steps as are necessary to
disseminate the Offer Documents and any other documents necessary to consummate
the Offer and the Merger, the Parent and Merger Sub and each of their affiliates
and associates shall hold in confidence the information contained in any of such
labels, lists and files, shall use such information only in connection with the
Offer and the Merger, and, if this Agreement is terminated, shall promptly
deliver to the Company all copies of such information then in their possession
or under their control.


          (d)  Change in Law. Subject to the terms and conditions of this
Agreement, if there shall occur a change in Law or in a binding judicial
interpretation of existing Law which would, in the absence of action by the
Company or the Board, prevent Merger Sub, were it to acquire a majority of the
shares of Company Common Stock then outstanding on a fully diluted basis, from
approving and adopting this Agreement by its affirmative vote as the holder of a
majority of the outstanding shares of Company Common Stock and without the
affirmative vote of any other shareholder, the Company will use its reasonable
efforts to promptly take or cause such action to be taken.

     SECTION 1.4.  Directors.

          (a)  Appointment of Directors.  Promptly upon the purchase of shares
of Company Common Stock pursuant to the Offer, and from lime to time thereafter,
the Parent shall be entitled to designate such number of directors, rounded up
to the next whole number, as will give the Parent representation on the Board of
Directors equal to the product of (i) the number of directors then on the Board
of Directors and (ii) the percentage that the number of shares of Company Common
Stock purchased by Merger Sub or the Parent or any affiliate pursuant to the
Offer bears to the number of shares of Company Common Stock then outstanding
(the "Percentage"), and the Company shall, upon request by the Parent, promptly
increase the size of the Board of Directors and/or exercise its reasonable
efforts to secure the resignations of such number of directors as is necessary
to enable the Parent's designees to be elected to the Board of
<PAGE>

Directors and shall cause the Parent's designees to be so elected. At the
request of the Parent, the Company will use its reasonable efforts to cause such
individuals designated by the Parent to constitute the same Percentage of (i)
each committee of the Board of Directors, (ii) the board of directors of REI
Barbados and (iii) the committees of the board of directors of REI Barbados. The
Company's obligations to appoint designees to the Board of Directors shall be
subject to Section 14(f) of the Exchange Act. The Company shall take, at its
expense, all action necessary to effect any such election, and shall include in
the Schedule 14D-9 the information required by Section 14(f) of the Exchange Act
and Rule 14f-l promulgated thereunder. The Parent will supply to the Company in
writing and be solely responsible for any information with respect to itself and
its nominees, directors and affiliates required by Section 14(f) and Rule 14f-l.
Notwithstanding anything stated herein, if shares of Company Common Stock are
purchased pursuant to the Offer, Parent and Merger Sub shall use reasonable
efforts to assure that until the Effective Time, the Company's Board of
Directors has at least one director who is a director on the date hereof and is
not an employee of the Company.

          (b)  Continuing Directors. Following the election or appointment of
the Parent's designees pursuant to this Section 1.4 and prior to the Effective
Time, the approval of a majority of the directors of the Company then in office
who are not designated by the Parent (the "Continuing Directors") shall be
required to authorize (and such authorization shall constitute the authorization
of the Board of Directors and no other action on the part of the Company,
including any action by any other director of the Company, shall be required to

Common Stock issued and outstanding immediately prior to the Effective Time

converted into the right to receive cash in the amount of the Merger
Consideration. As a result of the Merger and without any action on the part of

shall cease to be outstanding and shall be canceled and retired and shall cease
to exist, and each holder of shares of Company Common Stock (other than the

accordance with Section 3.2 upon the surrender of a certificate or certificates
(a "Certificate") representing such shares of Company Common Stock or, with
respect to Dissenting Shares, payment of the appraised value of Dissenting
Shares in accordance with Section 3.6.

prior to the Effective Time under the Company Option Plans, whether or not then
exercisable, shall (by all appropriate and necessary action taken prior to the
date of this Agreement of the Board of Directors or such committee or committees
of the Board of Directors as are vested with authority to administer the Company
Option Plans) be canceled. In cancellation thereof, each holder of an Option
(other than Excluded Options) shall be entitled to receive, for each share of
Company Common Stock subject to an Option (other than Excluded Options), an
amount in cash equal to the excess, if any, of the Merger Consideration over the
per share exercise price of such Option, without interest. The amounts payable
pursuant to this Section 3.1(d) shall be subject to all applicable withholding
of taxes. The Company shall use its reasonable efforts to obtain all necessary
consents, if any, of the holders of Options to the cancellation of the Options
in accordance with this Section 3.1(d). "Excluded Options" shall mean the
options of the holders set forth in Section 3.1(d) of the Company Disclosure
Letter which such holders have agreed will be cancelled without payment at the
Effective Time.

          (e)  Warrants.  All warrants (individually, a "Warrant" and

immediately prior to the Effective Time, whether or not then exercisable, shall
(by all appropriate and necessary action taken prior to the date of the Board of
Directors) be canceled and each holder of a Warrant shall be entitled to
receive, for each share of Company Common Stock subject to a Warrant, an amount
in cash equal to the excess, if any, of the Merger Consideration over the per
share exercise price of such Warrant, without interest. The amounts payable
pursuant to this Section 3.1(e) shall be subject to all applicable withholding
<PAGE>

of taxes. The Company shall use its reasonable efforts to obtain all necessary
consents, if any, of the holders of Warrants to the cancellation of the Warrants
in accordance with this Section 3.1(e).

          (f)  Convertible Notes.  The Convertible Notes outstanding immediately
prior to the Effective Time shall be canceled and the holders of the Convertible
Notes shall be entitled to receive an amount in cash equal to (i) the Merger
Consideration, times (ii) the number of shares of Company Common Stock that
would be issuable to such holders upon conversion of the Convertible Notes,
based on the Merger Consideration (i.e., one share of Company Common Stock for
each $14.85 principal amount of the Convertible Notes). No consideration or
other value shall be paid to the holders of the Convertible Notes under this
Section 3.1(f) in respect of the reset rights granted to the holders of the
Convertible Notes pursuant to Section 9.6(j) of the Securities Purchase
Agreement dated as of July 19, 1996, as amended by Amendment No. 1, dated as of
March 31, 1997,and as further amended by the letter agreement dated April 24,

pursuant to this Section 3.1(f) shall be subject to all applicable withholding
of taxes. The Company shall use its reasonable efforts to obtain all necessary
consents, if any, of the holders of the Convertible Notes to the cancellation of
the Convertible Notes in accordance with this Section 3.1(f).

     SECTION 3.2.  Exchange of Certificates.

          (a)  Paying Agent. Prior to the Effective Time, the Parent shall
appoint a commercial bank or trust company having net capital of not less than
$20 million, or such other party reasonably satisfactory to the Company, to act
as paying agent hereunder for payment of the Merger Consideration upon surrender
of Certificates (the "Paying Agent"). The Parent shall take all steps necessary
to cause the Surviving Corporation, the Company or Merger Sub to provide the
Paying Agent with cash in amounts necessary to pay for all the shares of Company
Common Stock pursuant to Section 3.1(c) and, in connection with the Options,
pursuant to Section 3.1(d), in connection with the Warrants, pursuant to Section
3.1(e), and in connection with the Convertible Notes, pursuant to Section
3.1(f), as and when such amounts are needed by the Paying Agent to fund the
payment of checks presented to the Paying Agent. Such amounts shall hereinafter
be referred to as the "Exchange Fund."

          (b)  Mailing.  As soon as practicable after the Effective Time, the
Parent shall cause the Paying Agent to mail to each holder of record of shares
of Company Common Stock immediately prior to the Effective Time (i) a letter of
transmittal which shall specify that delivery shall be effected, and risk of
loss and title to such Certificates shall pass, only upon delivery of the
Certificates to the Paying Agent and which letter shall be in such form and have
such other provisions as the Parent may reasonably specify and (ii) instructions
for effecting the surrender of such Certificates in exchange for the Merger
Consideration. Upon surrender of a Certificate to the Paying Agent together with
such letter of transmittal, duly executed and completed in accordance with the
instructions thereto, and such other documents as may reasonably be required by
the Paying Agent, the holder of such Certificate shall be entitled to receive in
exchange therefor the amount of cash into which shares of Company Common Stock
theretofore represented by such Certificate shall have
<PAGE>

been converted pursuant to Section 3.1, and the shares represented by the
Certificate so surrendered shall forthwith be canceled. No interest will be paid
or will accrue on the cash payable upon surrender of any Certificate. In the
event of a transfer of ownership of Company Common Stock which is not registered
in the transfer records of the Company, payment may be made with respect to such
Company Common Stock to such a transferee if the Certificate representing such
shares of Company Common Stock is presented to the Paying Agent, accompanied by
all documents required to evidence and effect such transfer and to evidence that
any applicable stock transfer taxes have been paid. Until surrendered as
contemplated by this Section 3.2, each Certificate shall be deemed, at any time
after the Effective Time, to represent only the right to receive upon such
surrender the amount of cash into which shares of Company Common Stock
theretofore represented by such Certificate shall have been converted pursuant
to Section 3.1.

          (c)  No Transfers.  At and after the Effective Time, there shall be no
transfers on the stock transfer books of the Company of the shares of Company
Common Stock which were outstanding immediately prior to the Effective Time. If,
after the Effective Time, Certificates are presented to the Surviving
Corporation, they shall be canceled and exchanged as provided in this Article
III.

          (d)  Unclaimed Portion of Exchange Fund. Any portion of the Exchange
Fund (including the proceeds of any interest and other income received by the
Paying Agent in respect of all such funds) that remains unclaimed by the former
shareholders of the Company six months after the Effective Time shall be
delivered to the Surviving Corporation. Any former shareholders of the Company
who have not theretofore complied with this Article III shall thereafter look
only to the Surviving Corporation for payment of any Merger Consideration that
may be payable upon surrender of any Certificates such shareholder holds, as
determined pursuant to this Agreement, without any interest thereon.

          (e)  No Liability.  None of the Parent, the Company, the Surviving
Corporation, the Paying Agent or any other person shall be liable to any former
holder of shares of Company Common Stock for any amount properly delivered to a
public official pursuant to applicable abandoned property, escheat or similar
Laws.

          (f)  Lost Certificates.  If any Certificate shall have been lost,
stolen or destroyed, upon the making of an affidavit of that fact by the person
claiming such Certificate to be lost, stolen or destroyed and, if required by
the Surviving Corporation, the posting by such person of a bond in such
reasonable amount as the Surviving Corporation may direct as indemnity against
any claim that may be made against it with respect to such Certificate, the
Paying Agent will issue in exchange for such lost, stolen or destroyed
Certificate the Merger Consideration payable in respect thereof pursuant to this
Agreement.

          (g)  Company ESPP.  Prior to any public announcement that it has
entered into this Agreement, the Company shall have taken all corporate action
necessary to amend its 1994 Stock Purchase Plan (the "Company ESPP") such that,
following the amendment of the Company ESPP, (i) no person shall commence to
participate therein, (ii) no participant shall be permitted to increase the
amount of payroll deductions in respect thereof, (iii) the "Stock Purchase
Date"
<PAGE>

(as defined in the Company ESPP) to occur on or first following amendment of the
ESPP (whichever is earlier) shall be the final date on which Company Common
Stock is purchased thereunder, and (iv) the Company ESPP shall be terminated
effective on the Effective Date. Promptly following such Stock Purchase Date,
any payroll deductions not applied to the purchase of shares of Company Common
Stock shall be remitted to participants.

          SECTION 3.3. Adjustments to Prevent Dilution. In the event that prior
to the Effective Time there is a change in the number of shares of Company
Common Stock or securities convertible or exchangeable into or exercisable for
shares of Company Common Stock issued and outstanding as a result of a
reclassification, stock split (including a reverse stock split), stock dividend
or distribution or similar transaction, the Merger Consideration shall be
equitably adjusted to eliminate the effects of that event.

          SECTION 3.4. Dissenting Shares. Notwithstanding anything in this
Agreement to the contrary, if required by the MBCA, but only to the extent
required thereby, shares of Company Common Stock outstanding immediately prior
to the Effective Time and held by a holder who has not voted in favor of the
Merger and who has demanded appraisal for such shares in accordance with Section
302A.473 of the MBCA ("Dissenting Shares") shall not be converted into the right
to receive the Merger Consideration as provided in Sections 3.1 and 3.2, unless
and until such holder fails to perfect or withdraws or otherwise loses his right
to appraisal and payment under the MBCA. If, after the Effective Time, any such
holder fails to perfect or withdraws or loses his right to appraisal, such
Dissenting Shares shall thereupon be treated as if they had been converted as of
the Effective Time into the right to receive the Merger Consideration, if any,
to which such holder is entitled, without interest or dividends thereon. The
Company shall give the Parent prompt notice of any demands received by the
Company for appraisal of shares and, prior to the Effective Time, the Parent
shall have the right to participate in all negotiations and proceedings with
respect to such demands. Prior to the Effective Time, the Company shall not,
except with the prior written consent of the Parent, make any payment with
respect to, or settle or offer to settle, any such demands.

          SECTION 3.5.  Merger Without Meeting of Shareholders.
Notwithstanding the foregoing, if Merger Sub, or any other direct or indirect
Subsidiary of the Parent, shall acquire at least 90 percent of the outstanding
shares of Company Common Stock pursuant to the Offer, the parties hereto shall
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 302A.621 of
the MBCA.

ARTICLE IV
REPRESENTATIONS AND WARRANTEES OF THE COMPANY

          Subject to the letter of the Company, dated the date hereof and
addressed to the Parent and Merger Sub (the "Company Disclosure Letter"), the
Company hereby represents and warrants to the Parent and Merger Sub that:

          SECTION 4.1. Organization and Qualifications; Subsidiaries.
<PAGE>

               (a)  Each of the Company and Recovery Engineering International,
Ltd., a Barbados corporation ("REI Barbados") (i) is a corporation, partnership
or other legal entity duly incorporated or organized, validly existing and in
good standing under the laws of the jurisdiction of its incorporation or
organization and (ii) has the requisite power and authority and all necessary
governmental approvals to own, lease and operate its properties and to carry on
its business as it is now being conducted, except, in the case of this clause
(ii), where the failure to have such power, authority and governmental approvals
would not, individually or in the aggregate, have a Company Material Adverse
Effect (as defined below). Each of the Company and REI Barbados is duly
qualified or licensed as a foreign corporation to transact business, and is in
good standing, in each jurisdiction where the character of the properties owned,
leased or operated by it or the nature of its business makes such qualification
or licensing necessary, except for such failures to be so qualified or licensed
and in good standing that would not, individually or in the aggregate, have a
Company Material Adverse Effect. For purposes of this Agreement, a "Company
Material Adverse Effect" shall mean any change or effect (i) that is materially
adverse to the business, assets, financial condition or results of operations of
the Company and REI Barbados, taken as a whole, (ii) that materially adversely
affects the ability of the Company to consummate the transactions contemplated
by this Agreement or that would prevent or materially delay consummation of the
Merger, or (iii) that materially adversely affects the ability of the Company to
conduct its business after the Closing consistent with the manner conducted in
the past.

               (b)  For purposes of this Agreement, a "Subsidiary" means, with
respect to the Parent, the Company or any other person, any entity of which the
Parent, the Company or such other person, as the case may be (either alone or
through or together with any other Subsidiary), owns, directly or indirectly,
stock or other equity interests the holders of which are generally entitled to
more than 50% of the vote for the election of the board of directors or other
governing body of such corporation or other legal entity.

          SECTION 4.2. Articles of Incorporation and Bylaws. The Company has
heretofore made available to the Parent a complete and correct copy of the
articles of incorporation and the bylaws or equivalent organizational documents,
each as amended to the date hereof, of the Company and REI Barbados. Such
articles of incorporation, bylaws and equivalent organizational documents are in
full force and effect. The Company is not in violation of any provision of its
articles of incorporation or bylaws. REI Barbados is not in violation of any
provision of its articles of incorporation, bylaws or equivalent organizational
documents, except for such violations that would not, individually or in the
aggregate, have a Company Material Adverse Effect.

          SECTION 4.3. Capitalization.

               (a) The authorized capital stock of the Company consists of
100,000,000 shares of capital stock, all of which is Company Common Stock. As of

Common Stock were reserved for issuance pursuant to the Company ESPP (with

Stock and the current contribution rates of participants in the Company ESPP at
the date of this Agreement), (E) up to 1,377,410 shares of Company Common Stock
were reserved for issuance upon conversion of the Convertible Notes at a

obligating the Company or REI Barbados to issue, transfer, grant or sell any
shares of capital stock of, or other equity interests in, or securities
convertible into or exchangeable for any capital stock or other equity interests

sets forth, for each Company Stock Option, the holder and the exercise price
thereof. After the Effective Time, the Surviving Corporation will have no
obligation to issue, transfer or sell any shares of capital stock of the Company
or the Surviving Corporation pursuant to any Company Option Plan. Except as set
forth in Section 4.3 of the Company Disclosure Letter, there are no voting
trusts or other agreements or understandings to which the Company or REI
Barbados is a party with respect to the voting of capital stock of the Company
or REI Barbados. All shares of outstanding Company Common Stock have been duly
authorized, validly issued and are nonassessable and all shares of Company
Common Stock subject to issuance as aforesaid, upon issuance on the terms and
conditions specified in the instruments pursuant to which they are issuable,
will be duly authorized, validly issued, fully paid and nonassessable. Except as
set forth in Section 4.3 of the Company Disclosure Letter, there are no
outstanding contractual obligations of the Company or REI Barbados to
repurchase, redeem or otherwise acquire any shares of Company Common Stock or
any other shares of capital stock of the Company or REI Barbados, or make any
material investment (in the form of a loan, capital contribution or otherwise)
in REI Barbados or any other person.
<PAGE>

               (b) Each outstanding share of capital stock of REI Barbados is
duly authorized, validly issued, fully paid and nonassessable and each such
share is owned by the Company free and clear of all security interests, liens,
claims, pledges, options, rights of first refusal, agreements, limitations on
voting rights, charges and other encumbrances of any nature whatsoever
(collectively, "Liens"). Section 4.3 of the Company Disclosure Letter sets forth
the authorized capital stock and the number of issued and outstanding shares of
capital stock of REI Barbados. Except for REI Barbados, neither the Company nor
REI Barbados owns directly or indirectly any interest or investment (whether
equity or debt) in any corporation, partnership, joint venture, business, trust
or other entity. REI Barbados (i) has not engaged in any business activity, (ii)
does not have any liabilities of any kind, (iii) has assets with a value of less
than $5,000, (iv) has not entered into any Contracts, and (v) is not the subject
of any Litigation.

          SECTION 4.4. Authority Relative to This Agreement. The Company has all
necessary corporate power and authority to execute and deliver this Agreement,
the Option Agreement and the documents contemplated hereby or thereby or
executed in connection herewith or therewith to which the Company is a party
(the Option Agreement and such other agreements and documents, collectively, the
"Ancillary Documents"), to perform its obligations hereunder and thereunder and,
subject to adoption of this Agreement by the Required Company Vote (as defined
in Section 4.13), if required by applicable Laws, to consummate the transactions
contemplated hereby and thereby (the "Transactions"). The execution and delivery

by the Company of the Transactions have been duly and validly authorized by all
necessary corporate action and no other corporate proceedings on the part of the
Company are necessary to authorize this Agreement or any Ancillary Document or

required by applicable Laws, and (ii) the Merger Filing). This Agreement and any
Ancillary Document have each been or will be duly and validly executed and
delivered by the Company and, assuming the due authorization, execution and
delivery thereof by the Parent and Merger Sub, constitute or will constitute the
legal, valid and binding obligation of the Company, enforceable against the
Company in accordance with their respective terms, except as enforcement may be
limited by bankruptcy, insolvency, moratorium or other similar laws relating to
creditors rights generally and by general equitable principles (regardless of
whether such enforceability is considered in a proceeding in equity or at law).

          SECTION 4.5. No Conflict; Required Filings and Consents; Certain
Contracts.

               (a) Except as set forth in Section 4.5(a) of the Company

asset of the Company or REI Barbados is bound or affected or, directly or
<PAGE>

indirectly, result in any of the consequences referred to in subsection (a) of
Exhibit A hereto, or (iii) conflict with or result in any breach of or
constitute a default (or an event which with notice or lapse of time or both
would become a default) under, result in the loss (by the Company, REI Barbados
or the Surviving Corporation) or modification in a manner materially adverse to
the Company and REI Barbados of any material right or benefit under, or give to
others any right of termination, amendment, acceleration, repurchase or
repayment, increased payments or cancellation of, or result in the creation of a
Lien or other encumbrance on any property or asset of the Company or REI
Barbados pursuant to, any note, bond, mortgage, indenture, contract, agreement,
lease, license, permit, franchise, or other instrument or obligation, whether
written or oral (collectively, "Contracts"), to which the Company or REI
Barbados is a party or by which the Company or REI Barbados or any property or
asset of the Company or REI Barbados is bound or affected, except, in the case
of clauses (ii) and (iii), for any such conflicts, violations, breaches,
defaults or other occurrences which would not, individually or in the aggregate,
have a Company Material Adverse Effect.

               (b) The execution and delivery of this Agreement and the
Ancillary Documents by the Company do not, and the performance of its
obligations under this Agreement and the Ancillary Documents and the
consummation of the Transactions by the Company will not, require any consent,
approval, authorization or permit of, or filing with or notification to, any
federal, state or local governmental or regulatory agency, authority, commission
or instrumentality, whether domestic or foreign (each a "Governmental Entity"),
except (i) for (A) applicable requirements of the Exchange Act and state
securities or "blue sky" laws ("Blue Sky Laws"), (B) the pre-merger notification
requirements of the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended, and the rules and regulations thereunder (the "HSR Act"), and (C) the
Merger Filing, and (ii) where the failure to obtain such consents, approvals,
authorizations or permits, or to make such filings or notifications, would not,
individually or in the aggregate, have a Company Material Adverse Effect.

               (c) Except as set forth in Section 4.5(c) of the Company
Disclosure Letter or in the Contracts filed (or incorporated) as exhibits to the
Company's Annual Report on Form 10-K for the year ended January 3, 1999 or the
other Company SEC Reports (as defined in Section 4.7) filed thereafter, there
are no Contracts to which the Company is a party or by which the Company or any
asset of the Company is bound, which by its terms limits in any material respect
the ability of the Company or, after consummation of the Transactions, would by
its terms limit in any material respect the ability of the Parent or any of its
affiliates, to engage in any business in any area or for any period.

          SECTION 4.6. Compliance. Except as set forth in Section 4.6 of the
Company Disclosure Letter, neither the Company nor REI Barbados is in conflict

          SECTION 4.7. SEC Reports and Financial Statements. Each form, report,
schedule, registration statement and definitive proxy statement filed by the
Company with the SEC since January 1, 1996 and prior to the date hereof
(including exhibits and any amendments thereto) (as such documents have been
amended prior to the date hereof, the "Company SEC Reports"), as of their
respective dates, complied in all material respects with the applicable
requirements of the Securities Act of 1933, as amended (the "Securities Act")
and the Exchange Act and the rules and regulations thereunder. None of the
Company SEC Reports, as of their respective dates, contains any untrue statement
of a material fact or omits to state a material fact required to be stated
therein or necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading. The Company has made
available to the Parent true, accurate and complete copies of all of the Company
SEC Reports. The consolidated financial statements (including any notes and
related schedules) of the Company and REI Barbados included in such reports
comply as to form in all material respects with applicable accounting
requirements and with the published rules and regulations of the SEC with
respect thereto, have been prepared in accordance with generally accepted
accounting principles applied on a consistent basis throughout the periods
involved (except as may be indicated in the notes thereto or, in the case of the
unaudited interim financial statements, as permitted by Form 10-Q of the SEC)
and fairly present in all material respects (subject, in the case of the
unaudited interim financial statements, to normal, year-end audit adjustments)
the consolidated financial position of the Company and REI Barbados as at the
dates thereof and the consolidated results of their operations and cash flows
for the periods then ended. Neither the Company nor REI Barbados has any
liabilities or obligations (whether absolute, accrued, fixed, contingent,
liquidated, unliquidated or otherwise) of any nature, except liabilities,
obligations or contingencies (a) which are reflected on the audited balance
sheet of the Company and REI Barbados as at January 3, 1999 (including the notes
thereto), or (b) which (i) were incurred in the ordinary course of business
after January 3, 1999 and consistent with past practices and which would not,
individually or in the aggregate, have a Company Material Adverse Effect, (ii)
are disclosed or reflected in the Company SEC Reports filed after January 3,
1999 and prior to the date of this Agreement or (iii) would not, individually or
in the aggregate, have a Company Material Adverse Effect. Since January 1, 1996,
the Company has timely filed with the SEC all forms, reports and other documents
required to be filed prior to the date hereof, and REI Barbados has not filed,
or been required to file, any form, report or other document with the SEC, in
each case, pursuant to the Securities Act, the Exchange Act or the rules and
regulations thereunder.

          SECTION 4.8. Absence of Certain Changes or Events. Except as set forth
in Section 4.8 of the Company Disclosure Letter, as contemplated by this
Agreement or as disclosed in any Company SEC Report filed prior to the date of
this Agreement, since January 3, 1999, (i) the Company and REI Barbados have
conducted their respective businesses only in the ordinary course, consistent
with past practice, (ii) there has not occurred or arisen any event that,
individually or in the aggregate, has had or would be reasonably expected to
have a Company Material Adverse Effect excluding any circumstance, fact, change,
development, effect or impairment resulting from (A) the entering into of this
Agreement and the announcement thereof and the transactions contemplated hereby
and (B) changes in general economic, financial, regulatory, political or market
conditions, and (iii) neither the Company nor REI Barbados has taken any action
<PAGE>

which, if taken after the date hereof, would constitute a violation of or
require the Parent's consent under Section 6.1.

          SECTION 4.9. Litigation. Except as disclosed in Section 4.9 of the
Company Disclosure Letter or in the Company SEC Reports, there are (i) no
claims, suits, actions, proceedings, arbitrations, investigations or audits
(collectively, "Litigation") pending or, to the knowledge of the Company's
executive officers, threatened, or (ii) no investigations or reviews by any
Governmental Entity pending or, to the knowledge of the Company's executive
officers, threatened, against, relating to or affecting the Company or REI
Barbados, which in either case would have, individually or in the aggregate, a
Company Material Adverse Effect, nor is there any judgment, decree, order,
injunction, writ or rule of any court, governmental department, commission,
agency, instrumentality or authority or any arbitrator outstanding against the
Company or REI Barbados.

          SECTION 4.10. Information Statement. None of the information contained
in the Schedule 14D-9, the information statement, if any, filed by the Company
in connection with the Offer pursuant to Rule 14f-1 under the Exchange Act (the
"Information Statement"), or incorporated by reference therein or any amendment
or supplement thereto, at the respective times such documents are filed with the
SEC or first published, sent or given to the Company's shareholders, contain or
will contain any untrue statement of a material fact or omit or will omit to
state any material fact required to be stated therein or necessary in order to
make the statements therein, in the light of the circumstances under which they
are made, not misleading, except that no representation is made by the Company
with respect to information supplied by the Parent or Merger Sub specifically
for inclusion in the Schedule 14D-9 or Information Statement or any amendment or
supplement. None of the information supplied or to be supplied by the Company
for inclusion or incorporation by reference in the Offer Documents will, at the
date of filing with the SEC, contain any untrue statement of a material fact or
omit to state any material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they were made, not misleading. If at any time prior to the Effective Time the
Company's executive officers shall obtain knowledge of any facts with respect to
itself, any of its officers and directors or REI Barbados that would require the
supplement or amendment to any of the foregoing documents in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, or to comply with applicable Laws, such amendment or
supplement shall be promptly filed with the SEC and, as required by Law,
disseminated to the shareholders of the Company, and in the event the Parent
shall advise the Company as to its obtaining knowledge of any facts that would
make it necessary to supplement or amend any of the foregoing documents, the
Company shall promptly amend or supplement such document as required and
distribute the same to its shareholders.

          SECTION 4.11.  Employee Benefit Plans.

               (a) Section 4.11 of the Company Disclosure Letter sets forth a
list of each material pension, retirement, savings, disability, dental, health,
life, death benefit, group insurance, profit-sharing, deferred compensation,
stock purchase, stock option (or other equity award), bonus, incentive,
termination, severance pay or other employee benefit plan, trust,
<PAGE>

arrangement, contract, commitment, agreement or policy (collectively, "Benefit
Plans") sponsored or maintained by the Company or REI Barbados, in which present
or former employees or directors of the Company or REI Barbados (or any
beneficiary or dependent of the foregoing) participate, or pursuant to which the
Company or REI Barbados may have any liability (contingent or otherwise)
(collectively, the "Company Benefit Plans"). True and complete copies of the
Company Benefit Plans (together with such other information related thereto as
the Parent may reasonably have requested) have been delivered to the Parent.

               (b) Except as set forth in Section 4.11 of the Company Disclosure
Letter and except as would not, individually or in the aggregate, have a Company
Material Adverse Effect: (A) the Company Benefit Plans have been administered
and are in compliance with the terms of such plan and all applicable Laws, (B)
no "reportable event" (as such term is used in Section 4043 of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA") (other than those
events for which the 30 day notice has been waived pursuant to the regulations),
"prohibited transaction" (as such term is used in Section 406 of ERISA or
Section 4975 of the Internal Revenue Code of 1986, as amended (the "Code") or
"accumulated funding deficiency" (as such term is used in Section 412 or 4971 of
the Code) has heretofore occurred with respect to any Company Benefit Plan and
(C) each Company Benefit Plan intended to qualify under Section 401(a) of the
Code has received a favorable determination from the IRS regarding its qualified
status and no event has occurred that could reasonably be expected to result in
the loss of such qualified status.

               (c) There is no litigation or administrative or other proceeding,
or any claim, suit, audit or investigation, involving any Company Benefit Plan
(other than routine claims for benefits), nor, to the knowledge of the Company's
executive officers, is any such proceeding threatened, in each case that,
individually or in the aggregate, would have a Company Material Adverse Effect.
Neither the Company nor REI Barbados has incurred, nor, to the knowledge of the
Company's executive officers, is reasonably likely to incur any withdrawal
liability with respect to any "multiemployer plan" (within the meaning of
Section 3(37) of ERISA) which remains unsatisfied in an amount which would have
a Company Material Adverse Effect. The termination of, or withdrawal from, any
Company Benefit Plan or multiemployer plan to which the Company or REI Barbados
contributes, will not subject the Company or REI Barbados to any liability under
Title IV of ERISA that individually or in the aggregate would have a Company
Material Adverse Effect.

               (d) At no time has the Company or REI Barbados (i) contributed to
or been required to contribute to, or incurred any withdrawal liability (within
the meaning of Section 4201 of ERISA) under, any "multiemployer plan" (within
the meaning of Sections 3(37) or 4001(a)(3) of ERISA), or (ii) contributed to or
been required to contribute to any "defined benefit plan" (within the meaning of
Section 3(35) of ERISA).

               (e) Other than as set forth on Section 4.11 of the Company
Disclosure Letter, the execution of, and performance of the transactions
contemplated in, this Agreement will not (either alone or upon the occurrence of
any additional or subsequent events) (i) constitute an event under any Company
Benefit Plan that will or may result in any payment (whether of severance pay or
otherwise), acceleration, forgiveness of indebtedness, vesting, distribution,
increase in benefits or obligation to fund benefits with respect to any current
<PAGE>

or former employee or director of the Company or REI Barbados, or (ii) result in
the triggering or imposition of any restrictions or limitations on the right of
the Company, the Parent or any of their Subsidiaries to amend or terminate any
Company Benefit Plan. No payment or benefit which will or may be made by the
Company, the Parent or any of their Subsidiaries will be characterized as an
"excess parachute payment," within the meaning of Section 280G(b)(1) of the
Code.

          SECTION 4.12. Labor and Employment Matters. Except as set forth in
Section 4.12 of the Company Disclosure Letter, (a) neither the Company nor REI
Barbados is a party to, or bound by, any collective bargaining agreement or
other Contract or understanding with a labor union or labor organization; and
(b) there is no (i) unfair labor practice, labor dispute (other than routine
individual grievances) or labor arbitration proceeding pending or, to the
knowledge of the Company's executive officers, threatened against the Company or
REI Barbados, (ii) activity or proceeding by a labor union or representative
thereof to organize any employees of the Company or REI Barbados, or (iii)
lockouts, strikes, slowdowns, work stoppages or threats thereof by or with
respect to such employees.

          SECTION 4.13. Vote Required. Unless the Merger may be consummated in
accordance with Section 302A.621 of the MBCA, in which case no vote of the
holders of the shares of Company Common Stock is required to approve this
Agreement and the Transactions, the affirmative vote of the holders of a
majority of the outstanding shares of Company Common Stock entitled to vote (the
"Required Company Vote") is the only vote or approval of the holders of any
class or series of the Company's capital stock necessary to adopt this Agreement
and approve the transactions contemplated hereby, except those approvals which
have heretofore been obtained (assuming that neither the Parent nor its
affiliates or associates (as defined in Section 302A.011 of the MBCA) are
"interested shareholders" of the Company under Section 302A.673 of the MBCA
immediately before the execution and delivery of this Agreement).

          SECTION 4.14. Opinion of Financial Advisor. The Company's Board of
Directors has received the opinion of Goldman, Sachs & Co., dated August 25,
1999, to the effect that, as of such date, the Merger Consideration to be
received by the shareholders of the Company is fair, from a financial point of
view, to such shareholders.

          SECTION 4.15. Brokers. Except as set forth in Section 4.15 of the
Company Disclosure Letter, no broker, finder or investment banker (other than
Goldman, Sachs & Co.) is entitled to any brokerage, finder's or other fee or
commission in connection with the Transactions based upon arrangements made by
or on behalf of the Company. The Company has previously delivered to Parent a
full and accurate copy of the Company's engagement letter with Goldman, Sachs &
Co. Section 4.15 of the Company Disclosure Letter sets forth the Company's
obligations to Goldman, Sachs & Co. in connection with its role as financial
advisor to the Company.

          SECTION 4.16. Taxes.

               (a) Except as set forth in Section 4.16(a) of the Company
Disclosure Letter:
<PAGE>

                    (i)    The Company and REI Barbados have timely filed (or
have had timely filed on their behalf) all Tax Returns required to be filed by
any of them. All such Tax Returns are true, correct and complete in all respects

have a Company Material Adverse Effect.

paid on their behalf) all Taxes due, except for Taxes the non-payment of which,
individually or in the aggregate, would not have a Company Material Adverse
Effect.

                    (iii)  The most recent financial statements contained in the
Company SEC Reports reflect full reserves for all Taxes payable by the Company
and REI Barbados for all Tax periods and portions thereof through the date of
such financial statements, except to the extent that any failure to so reserve,
individually or in the aggregate, would not have a Company Material Adverse
Effect.

                    (iv)   The Federal income Tax Returns of the Company have
not been audited. There are no taxable years currently under Audit, and the
Company has not been notified that any Audit by a Taxing Authority will commence
with respect to the Company or REI Barbados. There are no outstanding waivers or
pending requests for waivers to extend the statutory period of limitations to
assess any Taxes on the Company or REI Barbados, except to the extent any such
waiver or request for waiver, individually or in the aggregate, would not have a
Company Material Adverse Effect.

                    (v)    No deficiency or adjustment for any Taxes has been
proposed, asserted or assessed against the Company or REI Barbados that has not
been paid or fully reserved for on the financial statements of the Company,
except for deficiencies or adjustments that, individually or in the aggregate,
would not have a Company Material Adverse Effect, and, to the knowledge of the
Company's executive officers, no such deficiency or adjustment has been
threatened. There are no Liens for material Taxes upon the assets or property of
the Company or REI Barbados, except Liens for current Taxes not yet due.

                    (vi)   The Company and REI Barbados have withheld and paid
over to the relevant Tax Authority all Taxes required to have been withheld and
paid in connection with payments to employees, independent contractors,
creditors, shareholders or other third parties, except for such Taxes which,

Effect.

                    (vii)  Neither the Company nor REI Barbados is a party to
any Tax sharing, Tax allocation, Tax indemnity or similar agreement.

                    (viii) No "consent" within the meaning of Section 341(f) of
the Code has been filed with respect to the Company or REI Barbados.

               (b)  For purposes of this Agreement, the following terms shall
have the following meanings:

Contract or otherwise.

          SECTION 4.17.  Licenses and Permits.  Except as set forth in Section
4.17 of the Company Disclosure Letter, the Company and REI Barbados have all
necessary licenses, permits, certificates of need, approvals and authorizations
(collectively, "Permits") from all Governmental Entities required to lawfully
conduct their respective businesses as presently conducted, except for those
Permits the lack of which, individually or in the aggregate, would not have a
Company Material Adverse Effect, and (a) no Permit is subject to revocation or
forfeiture by virtue of any existing circumstances, (b) there is no Litigation
pending or, to the knowledge of the Company's executive officers, threatened to
modify or revoke any Permit, and (c) no Permit is subject to any outstanding
order, decree, judgment, stipulation, or investigation that would be likely to
affect such Permit, except for instances of any of the foregoing items (a)
through (c) which, individually or in the aggregate, would not have a Company
Material Adverse Effect.

          SECTION 4.18.  Title to Assets.

               (a)  Section 4.18(a) of the Company Disclosure Letter sets
forth a complete and accurate list of all leased and owned real properties of
the Company. The Company has good and marketable title to all of its real and
personal properties and assets reflected on the Balance Sheet of the Company at
July 4, 1999 included in the Company's Quarterly Report on Form 10-Q for the
period ended July 4, 1999 (the "1999 Balance Sheet"), free and clear of all
Liens except for (i) Liens which secure indebtedness which is properly reflected
in the 1999 Balance Sheet; (ii) Liens for Taxes accrued but not yet payable;
(iii) Liens arising as a matter of law in the ordinary course of business with
respect to obligations incurred after the date of the 1999 Balance Sheet,
provided that the obligations secured by such Liens are not delinquent; and (iv)
such imperfections of title and Liens, if any, as individually or in the
aggregate would not have a Company Material Adverse Effect. Except as set forth
in Section 4.18(a) of the Company Disclosure Letter, the Company owns, or has
<PAGE>

valid leasehold interests in, all properties and assets used by it in the
conduct of its business, except where the absence of such ownership or leasehold
interests would not individually or in the aggregate have a Company Material
Adverse Effect.


               (b)  Except as set forth in Section 4.18(b) of the Company
Disclosure Letter, the Company does not have any legal obligation, absolute or
contingent, to any other person to sell or dispose of any of its assets, other

aggregate value in excess of $250,000.

          SECTION 4.19.  Material Contracts.  Section 4.19 of the Company

Contracts containing covenants by the Company restricting its ability or the
ability of any affiliates of the Company to engage in any line of business, (iv)
Contracts to purchase materials, supplies or other assets, other than purchase

Company acts as distributor or sales agent for others, (vii) Contracts in which

of the Company (including intellectual property), other than the sale of

is a party or by which any of its assets are bound are valid and binding, in
full force and effect and enforceable against the parties thereto in accordance
with their respective terms, except where the failure to be so valid and
binding, in full force and effect or enforceable would not individually or in
the aggregate have a Company Material Adverse Effect. There is not under any
such Contract, any existing default, or event, which after notice or lapse of
time, or both, would constitute a default, by the Company, or to the knowledge
of the Company's executive officers, any other party, other than any such
<PAGE>

defaults or events which, individually or in the aggregate, would not have a
Company Material Adverse Effect.

          SECTION 4.20.  Intellectual Property Rights.

               (a)  The Company and REI Barbados have and will, after giving
effect to the consummation of the Transactions, have to the same extent and on
the same terms as prior to the Closing, (i) valid rights to use, whether through
ownership, licensing or otherwise, all patents, trademarks, service marks, trade
dress, trade names, domain names, copyrights, trade secrets (where recognized by
applicable law), licenses, information, proprietary rights and processes that
are used in its business as now conducted (collectively the "Intellectual
Property Rights"), and (ii) except as disclosed in Section 4.20 of the Company
Disclosure Letter, the right to require the applicant of any Intellectual
Property Right which is an application to transfer ownership thereof and of the
related registration to the Company or REI Barbados once it issues.

               (b)  Except as disclosed in Section 4.20 of the Company
Disclosure Letter, no Intellectual Property Right is subject to any outstanding
judgment, injunction, order, decree or agreement restricting the use thereof by
the Company or REI Barbados, except for any judgment, injunction, order, decree
or agreement which would not reasonably be expected to have a Company Material
Adverse Effect.

               (c)  Each Intellectual Property Right which is a patent, patent
application, trademark registration, trademark application, service mark
registration, service mark application, domain name (with respect to domain
names, to the knowledge of the Company's executive officers), copyright
registration or copyright application, is set forth on Section 4.20 of the
Company Disclosure Letter. All registered patents, trademarks, domain names,
service marks and copyrights listed on Section 4.20 of the Company Disclosure
Letter are valid (when in use) and existing and in full force and effect, and
owned by the Company or REI Barbados free and clear of any Liens. Section 4.20
of the Company Disclosure Letter sets forth a complete and accurate list of all
Contracts in which the Company is a licensor or licensee of Intellectual
Property Rights.

               (d)  To the knowledge of the Company's executive officers, other
than as set forth on Section 4.20 of the Company Disclosure Letter: (i) no third
party has interfered with, infringed upon, misappropriated or otherwise come
into conflict with any of the Intellectual Property Rights except in such a way
as would not jeopardize the validity of such Intellectual Property Rights or the
ability of the Company or REI Barbados to use the registered patents or the
Intellectual Property Rights in substantially the manner they are used on the
date hereof, and (ii) neither the Company nor REI Barbados, by using the
Intellectual Property Rights, has materially interfered with, infringed upon,
misappropriated or otherwise come into conflict with any material registered
trademark of any third party nor, by using such registered patents, any material
registered patent of any third party.

          SECTION 4.21.  State Takeover Statutes Inapplicable.  From and after
the date hereof and at all times at or prior to the Effective Time, (i) Sections
302A.67l, 302A.673 and 302A.675 of the MBCA will be inapplicable to the Offer,
the Merger, this Agreement, the Ancillary Documents, the Tender and Option
<PAGE>

Agreement and the transactions contemplated hereby and thereby, and the Company
has received an opinion to that effect from Robins, Kaplan, Miller & Ciresi
L.L.P., and (ii) no other takeover Law in effect on the date hereof could affect
the ability of the Parent or Merger Sub to consummate the transactions
contemplated hereby or thereby or have, either individually or in the aggregate,
a Company Material Adverse Effect or a Parent Material Adverse Effect.

          SECTION 4.22.  Rights Agreement.  Pursuant to action of the Board of
Directors on August 25, 1999, the Company amended (the "Rights Amendment") the
Rights Agreement so that the Rights Agreement will not affect or be affected by
this Agreement, the Option Agreement, the Tender and Option Agreement, the
Offer, the announcement of the Offer, the purchase of shares of Company Common
Stock by the Parent or Merger Sub pursuant to the Offer, the Merger, or any
transaction contemplated hereby or thereby, and the Company has received an
opinion to that effect from Robins, Kaplan, Miller & Ciresi L.L.P. The
Distribution Date (as defined in the Rights Agreement) has not occurred. The
Rights Amendment has been duly authorized, executed and delivered by the Company
and is valid and enforceable in accordance with its terms.

          SECTION 4.23.  Year 2000.

               (a)  The Company is in the process of conducting an inventory and
assessment of all software, computers, network equipment, technical
infrastructure, production equipment and other equipment and systems that are
material to the operation of its business and that rely on, utilize or perform
date or time processing ("Systems") to ensure that the Systems are Year 2000
Compliant.

               (b)  The Company reasonably expects that implementation and
testing of the Systems to ensure that they are Year 2000 Compliant will be
completed by September 30, 1999. Any failure of any of the Company's Systems to
be Year 2000 Compliant has not had and is not reasonably expected to have a
Company Material Adverse Effect.

               (c)  In addition to upgrading its own Systems, the Company has
contacted certain significant suppliers to determine whether their Systems are
Year 2000 Compliant. The Company has not received any information which would
indicate that the Systems of its suppliers will not be Year 2000 Compliant to
the extent the same could reasonably be expected to result in any significant
disruption to the Company's sources of supplies.

               (d)  "Year 2000 Compliant" means a System will at all times: (i)
consistently and accurately handle and process date and time information and
data values before, during and after January 1, 2000, including but not limited
to accepting date input, providing date output, and performing calculations on
or utilizing dates or portions of dates; (ii) function accurately and in
accordance with its specifications without interruption, abnormal endings,
degradation, change in operation or other impact, or disruption of other
systems, resulting from processing date or time data with values, before, during
and after January 1, 2000; (iii) respond to and process two-digit date input in
a way that resolves any ambiguity as to century; and (iv) store and provide
output of date information in ways that are unambiguous as to century.
<PAGE>

          SECTION 4.24.  Insurance.  The Company and REI Barbados maintain in
force insurance policies and bonds in such amounts and against such liabilities
and hazards as are consistent with industry practice. A complete list of all
material insurance policies is set forth in Section 4.24 of the Company
Disclosure Letter. Except as set forth in Section 4.24 of the Company Disclosure
Letter, neither the Company nor REI Barbados is now liable, nor will any of them
become liable, for any retroactive premium adjustment not reflected in the 1999
Balance Sheet or otherwise provided for as set forth in Section 4.24 of the

requisite power and authority and all necessary governmental approvals to own,
lease and operate its properties and to carry on its business as it is now being
conducted, except where the failure to be so organized, existing or in good

individually or in the aggregate, have a Parent Material Adverse Effect (as
defined below). For purposes of this Agreement, a "Parent Material Adverse
Effect" shall mean any change or effect that adversely affects the ability of
the Parent to consummate the transactions contemplated by this Agreement in any
material respect, or that would prevent or delay in any material respect
consummation of the Merger.

of the
<PAGE>

Such certificates of incorporation, bylaws and equivalent organizational
documents are in full force and effect. The Parent is not in violation of any
provision of its certificate of incorporation or bylaws. Merger Sub is not in

this Agreement, the Ancillary Documents and the Tender and Option Agreement by
the Parent and Merger Sub and the consummation by the Parent and Merger Sub of
the transactions contemplated hereby and thereby have been duly and validly
authorized by all necessary corporate action and no other corporate proceedings
on the part of the Parent or Merger Sub are necessary to authorize this
Agreement, the Ancillary Documents and the Tender and Option Agreement or to
consummate the transactions contemplated hereby or thereby (other than the
Merger Filing). This Agreement, the Ancillary Documents and the Tender and
Option Agreement have each been duly and validly executed and delivered by the
Parent and Merger Sub and, assuming the due authorization, execution and
delivery thereof by the Company, constitute the legal, valid and binding
obligation of the Parent and Merger Sub, enforceable against the Parent and
Merger Sub in accordance with their respective terms, except as enforcement may
be limited by bankruptcy, insolvency, moratorium or other similar laws relating
to creditors rights generally and by general equitable principles (regardless of
whether such enforceability is considered in a proceeding in equity or at law).

the articles of incorporation or bylaws or equivalent organizational documents
of the Parent or Merger Sub, (ii) subject to making the filings and obtaining

for any such conflicts, violations, breaches, defaults or other occurrences
which would not, individually or in the aggregate, have a Parent Material
Adverse Effect.

                    (b)   The execution and delivery of this Agreement, the
Ancillary Documents and the Tender and Option Agreement by the Parent and Merger
Sub do not, and the performance of their respective obligations under this
Agreement, the Ancillary Documents and the Tender and Option Agreement and the
consummation of the transactions contemplated hereby and thereby by the Parent
and Merger Sub will not, require any consent, approval, authorization or permit
of, or filing with or notification to, any Governmental Entity, except (i) for
(A) applicable requirements, if any, of the Exchange Act or the Blue Sky laws,
(B) the premerger notification requirements of the HSR Act, and (C) the Merger

consummation of the Merger, or otherwise prevent the Parent or Merger Sub from
performing its respective obligations under this Agreement in any material
respect, and would not, individually or in the aggregate, have a Parent Material
Adverse Effect.

approve the transactions contemplated hereby.

          SECTION 5.8.  No Arrangements Triggering Section 302A.673 of the MBCA.
Neither the Parent nor, to the best of the knowledge of Parent's executive
officers, any of its affiliates or associates (each as defined in Section

contemplated hereby. Merger Sub has no Subsidiaries.

          SECTION 5.10. Financing.  At the consummation of the Offer and at the

ARTICLE VII
ADDITIONAL COVENANTS

          SECTION 7.1.  Access to Information.

               (a)  From the date hereof to the Effective Time, the Company
shall (and shall cause REI Barbados and their respective officers, directors,
employees, auditors and agents to) afford the officers, employees, auditors,
agents and advisors (the "Representatives") of the Parent access at all
reasonable times to its officers, employees, agents, properties, offices, plants
and other facilities, books, records (including auditors work papers) and Tax
Returns, and shall furnish such Representatives with all financial, operating
and other data and information as may be reasonably requested, and permit the
Parent to make such copies of documents and such inspections and investigations,
including, without limitation, such environmental assessments and testing as the
Parent may request. All information so obtained will be subject to the
Confidentiality Agreement, dated June 24, 1999, between and the Financial
Advisor on behalf of the Company and the Parent, as amended on July 27, 1999
(the "Confidentiality Agreement").

               (b)  No investigation pursuant to this Section 7.1 shall affect
any representation or warranty in this Agreement of any party hereto or any
condition to the obligations of the parties hereto.

          SECTION 7.2.  No Solicitation.

               (a)  The Company shall not, nor shall it permit REI Barbados, or
any officer or director to, and shall use its best efforts to cause the
employees, agents or Representatives of the Company and REI Barbados (including,
without limitation, any investment banker, attorney or accountant retained by
the Company or REI Barbados), not to, directly or indirectly, (i) initiate,
solicit or knowingly encourage, facilitate or assist (including by furnishing
any information or providing any access to the properties, books or records of
the Company) any inquiries or proposals that constitute, or could reasonably be
expected to lead to, a proposal or offer for a merger, consolidation, business
<PAGE>

combination, sale of assets representing a material portion of the assets of the
Company and REI Barbados, taken as a whole, sale of shares of capital stock
representing, individually or in the aggregate, 10% or more of the voting power
of the Company, including, without limitation, by way of a tender offer or
exchange offer by any person for shares of capital stock representing 10% or
more of the voting power of the Company, other than the Transactions (any of the
foregoing inquiries or proposals being referred to in this Agreement as an
"Acquisition Proposal"), (ii) engage in negotiations or discussions concerning,
or provide to any person or entity any information or data relating to the
Company or REI Barbados for the purposes of making, any Acquisition Proposal,
(iii) agree to, approve or recommend any Acquisition Proposal or (iv) take any
other action inconsistent with the obligations and commitments assumed by the
Company pursuant to this Section 7.2; provided, however, that nothing contained
in this Agreement shall prevent the Company or its Board of Directors from (A)
furnishing nonpublic information to, entering into customary confidentiality
agreements with, or entering into discussions or negotiations with, any person
or entity in connection with an unsolicited bona fide written Acquisition
Proposal to the Company or its shareholders, if the Company provides the Parent
with at least 2 business days' notice of its intent to do so and the Acquisition
Proposal is made in writing prior to Merger Sub and/or the Parent having
purchased any shares of Company Common Stock under the Offer and the Board of
Directors of the Company, by action of a majority of the entire Board of
Directors of the Company, determines in good faith that such Acquisition
Proposal constitutes, or is reasonably likely to lead to, a Superior Proposal or
(B) taking and disclosing to its shareholders a position with respect to such
Acquisition Proposal or making any other public disclosure that, in the opinion
of the Company's counsel, is required by applicable Laws; provided, however,
that the Board of Directors will not recommend that the shareholders of the
Company tender their shares of Company Common Stock into any tender offer unless
(i) the Board of Directors determines that such tender offer constitutes a
Superior Proposal and (ii) the Company has provided the Parent and Merger Sub
with not less than two business days' prior notice of its intent to do so. For
purposes of this Agreement, "Superior Proposal" means a bona fide written
Acquisition Proposal which was not solicited, encouraged or knowingly
facilitated in violation of this Section 7.2, and which was received in writing
by the Company prior to Merger Sub and/or the Parent having purchased any shares
of Company Common Stock under the Offer and which a majority of the members of
the Board of Directors of the Company determines in their good faith judgment
(after consultation with independent financial advisors) to be more favorable
from a financial point of view to the Company and its shareholders than the
Merger, after giving effect to any increase in the Merger Consideration offered
by the Parent and Merger Sub, and is reasonably capable of being completed,
taking into account all legal, financial, regulatory and other aspects of such
proposal; provided, however, that an Acquisition Proposal shall not constitute a
Superior Proposal if the Acquisition Proposal is subject to a financing
condition unless the Board of Directors, by action of a majority of the entire
Board of Directors in good faith, based on the advice of the Financial Advisor
or other nationally recognized investment banking firm, determines that the
Acquisition Proposal is readily financeable. The Company will immediately cease
and cause to be terminated any existing activities, discussions or negotiations
by the Company or its Representatives with any parties conducted heretofore with
respect to any of the foregoing, take the necessary steps to inform such parties
of the obligations undertaken in this Section 7.2., and request that such
parties promptly return all documents (and all copies thereof) furnished to them
<PAGE>

by the Company or its Representatives in connection with such activities,
discussions and negotiations. Nothing in this Section 7.2 shall (i) permit the
Company to terminate this Agreement (except as specifically provided in Article
IX hereof), or (ii) affect any other obligation of the Company under this
Agreement. For purposes of this Agreement, an Acquisition Proposal shall not be
deemed to exist solely as a result of a person filing a report on Schedule 13G
to report ownership of the Company Common Stock.

               (b)  The Company shall (i) promptly notify the Parent in writing
after receipt by the Company (or its Representatives) of any Acquisition
Proposal or any inquiries indicating that any person is considering making or
wishes to make an Acquisition Proposal and provide a copy of such Acquisition
Proposal or, in connection with any non-written inquiries or Acquisition
Proposal, provide a written statement setting forth in detail a description of
the inquiry or the terms and conditions of the Acquisition Proposal, (ii)
promptly notify the Parent in writing after receipt of any request for nonpublic
information relating to it or REI Barbados or for access to its or REI Barbados'
properties, books or records by any person that, to the knowledge of the
Company's executive officers, may be considering making, or has made, an
Acquisition Proposal and (iii) promptly keep the Parent advised of the status of
any such Acquisition Proposal, indication or request including, without
limitation, the identity of the party making such Acquisition Proposal,
indication or request, and all terms relating to such Acquisition Proposal.

               (c)  In no event will the Company provide any non-public
information regarding the Company to any party making an Acquisition Proposal
unless such party enters into a written confidentiality agreement containing
provisions substantially similar to those contained in the Confidentiality
Agreement.

          SECTION 7.3.  Directors and Officers Indemnification and Insurance

               (a)  From and after the Effective Time, the Parent shall cause
the Surviving Corporation to and the Surviving Corporation shall indemnify,
defend and hold harmless the present and former officers, directors, employees
and agents of the Company (each a "Covered Person") against all losses,
expenses, claims, damages, liabilities or amounts ("Losses") that are paid in
settlement (provided that such settlement has been approved by the Parent, such
approval not to be unreasonably withheld) of, or otherwise in connection with,
any claim, action, suit, proceeding or investigation (a "Claim"), based in whole
or in part on the fact that such person is or was a director, officer, employee
or agent of the Company and arising out of actions or omissions occurring at or
prior to the Effective Time (including, without limitation, the Transactions),
in each case to the full extent permitted under the MBCA and the Company's
articles of incorporation and bylaws as in effect on the date of this Agreement.
The Surviving Corporation shall pay any expenses in advance of the final
disposition of any such Claim to each Covered Person to the fullest extent
permitted under the MBCA upon receipt from the Covered Person to whom expenses
are advanced of an undertaking to repay such advances required under the MBCA.
The Surviving Corporation shall cooperate in the defense of any such matter.

               (b)  For a period of six years after the Closing Date (or in the
event any Claim is asserted within such six year period, until final
<PAGE>

disposition of that Claim), the Parent shall cause the Surviving Corporation to
keep in effect provisions in its articles of incorporation and bylaws providing
for exculpation of director liability, advancing expenses prior to disposition
of any Claim and its indemnification of the Covered Persons to the fullest
extent permitted under the MBCA, which provisions shall not be amended except as
required by applicable Law or except to make changes permitted by law that would
enlarge the right of indemnification of the Covered Persons.

               (c)  For a period of six (6) years after the Effective Time, the
Parent shall cause the Surviving Corporation to maintain in effect the current
policies of directors and officers liability insurance maintained by the Company
covering persons who are currently covered by the Company's officers and
directors liability insurance policies with respect to actions or omissions
occurring at or prior to the Effective Time to the extent that such policies are
available; provided, that policies of at least the same coverage containing
terms and conditions which are no less advantageous to the insureds may be
substituted therefor, provided, further, that in no event shall the Surviving
Corporation be required to expend amounts for premiums per annum in excess of
150% of the current annual premiums for the twelve-month period ending November
15, 1999 (which premium the Company represents and warrants to be $107,500 in
the aggregate for the policy year which began in November 1998) (the "Maximum
Premium") to maintain or procure insurance coverage pursuant to this Section
6.3, or, if the cost of such coverage exceeds the Maximum Premium, the maximum
amount of coverage that can be purchased for the Maximum Premium.

               (d)  From and after the Effective Time, the Parent agrees to
indemnify, defend and hold harmless the Covered Persons against all Losses that
are paid in settlement (provided that such settlement has been approved by the
Parent, such approval not to be unreasonably withheld) of, or otherwise in
connection with, a Claim based in whole or in part on the fact that such Covered
Person is or was a director or officer of the Company and arising out of actions
or omissions occurring at or prior to the Effective Time (including, without
limitation, the Transactions), in each case to the fullest extent permitted by
applicable Law and whether or not the Surviving Corporation is permitted by
applicable Law to provide any indemnity with respect to such Losses. The Parent
shall pay any expenses in advance of the final disposition of any such Claim to
each Covered Person to the fullest extent permitted by applicable Law upon
receipt from the Covered Person to whom such expenses are advanced of an
undertaking to repay such advances required under applicable Law. The Parent
shall cooperate in the defense of any such matter.

               (e)  If any Litigation described in this Section 7.3 (each, an
"Action") arises or occurs, the Surviving Corporation shall control the defense
of such Action with counsel selected by the Surviving Corporation, which counsel
shall be reasonably acceptable to the party seeking indemnification pursuant to
this Section 7.3 (each, an "Indemnified Party"); provided that the Indemnified
Party shall be permitted to participate in the defense of such Action through
counsel selected by the Indemnified Party, which counsel shall be reasonably
acceptable to the Surviving Corporation, at the Indemnified Party's expense.
Notwithstanding the foregoing, if there is any conflict between the Surviving
Corporation and any Indemnified Parties or there are additional defenses
available to any Indemnified Parties, the Indemnified Parties shall be permitted
to participate in the defense of such Action with counsel selected by the
Indemnified Parties, which counsel shall be reasonably acceptable to the
<PAGE>

Surviving Corporation, and the Indemnified Parties shall be indemnified
therefor; provided that the Surviving Corporation shall not be obligated to pay
the reasonable fees and expenses of more than one counsel for all Indemnified
Parties in any single Action except to the extent that, in the opinion of
counsel for the Indemnified Parties, two or more of such Indemnified Parties
have conflicting interests in the outcome of such Action. The Surviving
Corporation shall not be liable for any settlement effected without its written
consent, which consent shall not be unreasonably withheld.

               (f)  The provisions of this Section 7.3 shall survive the
consummation of the Merger and expressly are intended to benefit each of the
Covered Persons.

          SECTION 7.4.  Notification of Certain Matters.  The Parent shall give
prompt notice to the Company, and the Company shall give prompt notice to the
Parent, of (a) the occurrence or nonoccurrence of any event the occurrence or
nonoccurrence of which would be likely to cause any covenant, condition or
agreement contained in this Agreement or any Ancillary Document not to be
complied with or satisfied and (b) any failure of the Parent or the Company, as
the case may be, to comply with or satisfy any covenant, condition or agreement
to be complied with or satisfied by it hereunder; provided, however, that the
delivery of any notice pursuant to this Section 7.4 shall not limit or otherwise
affect the remedies available hereunder to the party receiving such notice.

          SECTION 7.5.  Restructuring of Merger.  Upon the mutual agreement of
the Parent and the Company, the Merger shall be restructured in the form of a
forward subsidiary merger of the Company into Merger Sub or any other affiliate
of the Parent, with Merger Sub or such affiliate being the surviving
corporation, or as a merger of the Company into the Parent, with the Parent
being the surviving corporation. In such event, this Agreement shall be deemed
appropriately modified to reflect such form of merger.

          SECTION 7.6.  Company Shareholder Meeting.  Subject to Section 3.5,
the Company shall (i) call a meeting of its shareholders (the "Shareholders
Meeting") for the purpose of voting upon the Merger, (ii) hold the Shareholders
Meeting as soon as practicable following the termination or expiration of the
Offer or the purchase of shares of Company Common Stock pursuant to the Offer,
(iii) submit this Agreement and the transactions contemplated hereby for
approval of the Company's shareholders at the Shareholders Meeting, and (iv)
include in the Proxy Statement the recommendation of its Board of Directors that
its shareholders approve this Agreement and the transactions contemplated
hereby; provided, however, it need not include such recommendation if it has
received a written opinion from outside counsel that such recommendation would
violate the Board of Directors' fiduciary duties under applicable Law. If the
Parent or Merger Sub purchases any Company Common Stock pursuant to the Offer,
the record date for the Shareholders Meeting shall be a date subsequent to the
date the Parent or Merger Sub becomes a record holder of Company Common Stock
purchased pursuant to the Offer.

          SECTION 7.7.  Proxy Statements.

               (a)  If required by applicable Law, the Company will, as soon as
practicable following the termination or expiration of the Offer, prepare and
file a preliminary Proxy Statement (such proxy statement, and any amendments or
<PAGE>

supplements thereto, the "Proxy Statement") or, if applicable, an information
statement with the SEC with respect to the Shareholders Meeting and will use its
reasonable efforts to respond to any comments of the SEC or its staff and to
cause the Proxy Statement to be cleared by the SEC as soon as practicable. The
Company will notify the Parent of the receipt of any comments from the SEC or
its staff and of any request by the SEC or its staff for amendments or
supplements to the Proxy Statement or for additional information and will supply
the Parent with copies of all correspondence between the Company or any of its
representatives, on the one hand, and the SEC or its staff, on the other hand,
with respect to the Proxy Statement or the Merger. The Company shall give the
Parent and its counsel (who shall provide any comments thereon as soon as
practicable) the opportunity to review the Proxy Statement prior to its being
filed with the SEC and shall give the Parent and its counsel (who shall provide
any comments thereon as soon as practicable) the opportunity to review all
amendments and supplements to the Proxy Statement and all responses to requests
for additional information and replies to comments prior to their being filed
with, or sent to, the SEC. Each of the Company and the Parent agrees to use its
reasonable efforts, after consultation with the other parties hereto, to respond
promptly to all such comments of and requests by the SEC. As promptly as
practicable after the Proxy Statement has been cleared by the SEC, the Company
shall mail the Proxy Statement to the shareholders of the Company. If at any
time prior to the approval of this Agreement by the Company's shareholders there
shall occur any event that should be set forth in an amendment or supplement to
the Proxy Statement, the Company will prepare and mail to its shareholders such
an amendment or supplement.

               (b)  The Company represents and warrants that the Proxy Statement
will comply as to form in all material respects with the Exchange Act and, at
the respective times filed with the SEC and distributed to shareholders of the
Company, will not contain any untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary in order to
make the statements therein, in the light of the circumstances under which they
were made, not misleading; provided, that the Company makes no representation or
warranty as to any information included in the Proxy Statement which was
provided by the Parent or Merger Sub. The Parent represents and warrants that
none of the information supplied by the Parent or Merger Sub for inclusion in
the Proxy Statement will, at the respective times filed with the SEC and
distributed to shareholders of the Company, contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading.

               (c)  The Company shall use its reasonable efforts to obtain the
necessary approvals by its shareholders of this Agreement and the transactions
contemplated hereby.

               (d)  The Parent agrees, subject to applicable Law, to cause all
shares of Company Common Stock purchased by Merger Sub and/or the Parent
pursuant to the Offer and all other shares of Company Common Stock owned by the
Parent, Merger Sub or any other Subsidiary or affiliate of the Parent to be
voted in favor of the approval of this Agreement and the transactions
contemplated hereby.

          SECTION 7.8.   Further Action, Reasonable Efforts.
<PAGE>

               (a)  Upon the terms and subject to the conditions hereof, each of
the parties hereto shall (i) make promptly its respective filings, and
thereafter make any other required submissions, under the HSR Act with respect
to the Transactions, and (ii) use reasonable efforts to take, or cause to be
taken, all appropriate action, and to do, or cause to be done, all things
necessary, proper or advisable under applicable Laws and regulations to
consummate and make effective the transactions contemplated hereby, including,
without limitation, using reasonable efforts to obtain all licenses, permits,
consents, approvals, authorizations, qualifications and orders of Governmental
Entities, make all filings and required submissions with Governmental Entities,
including foreign filings and submissions, and obtain all consents and approvals
from parties to Contracts with the Company and the Parent and their respective
Subsidiaries as are necessary for the consummation of the transactions
contemplated hereby; provided, however, that the Parent shall not be required by
any provision of this Agreement to take any action, including entering into any
consent decree that requires the divestiture of a material amount of assets of
the Parent or any of its Subsidiaries. Each of the Parent and the Company shall,
subject to the Parent's direction, use all its reasonable efforts to contest any
proceeding seeking a preliminary injunction or other legal impediment to, and to
resolve any objections as may be asserted by any Governmental Entity with
respect to, the Offer and/or the Merger under the HSR Act or any other antitrust
Laws; provided that the foregoing shall not require the Parent to take any
action that is reasonably likely to result in any of the consequences specified
in subsection (a) of Exhibit A. In case at any time after the Effective Time any
other action is necessary or desirable to carry out the purposes of this
Agreement, the proper officers and directors of each party to this Agreement
shall use their reasonable efforts to take all such action.

               (b)  Each party shall use its reasonable efforts not to take any
action, or enter into any transaction, which would result in a breach of any
covenant made by it in this Agreement.


               (c)  Each party hereto shall, subject to the fulfillment at or
before the Effective Time of each of the conditions of performance set forth
herein or the waiver thereof, perform such further acts and execute such
documents as may be reasonably required to effect the transactions contemplated
hereby.

          SECTION 7.9.  Public Announcements. The initial press release relating
to this Agreement shall be a joint press release. Thereafter, the Company and
the Parent shall consult with each other before issuing any press release or
otherwise making any public statements with respect to this Agreement or any of
the transactions contemplated hereby and shall not issue any such press release
or make any such public statement without the prior consent of the other party,
which consent shall not be unreasonably withheld or delayed; provided, however,
that a party may, without the prior consent of the other party, issue such press
release or make such public statement as may be required by Law or any listing
agreement or arrangement to which the Company or the Parent is a party with a
national securities exchange or The Nasdaq Stock Market if it has used all
reasonable efforts to consult with the other party and to obtain such party's
consent but has been unable to do so in a timely manner.

          SECTION 7.10.   Employee Benefits.
<PAGE>

               (a)  For a period of at least two years after the Effective Time,
the Parent will cause the Surviving Corporation to provide for the benefit of
the employees of the Company and REI Barbados benefits in the aggregate that are
(A) substantially equivalent to the benefits provided under Company Benefit
Plans in effect on the date of this Agreement, or (B) if equal to or greater
than the benefits described in clause (A) above, the benefits provided under
benefit plans maintained by the Parent for employees of the Parent and the
Parent Subsidiaries (other than the Surviving Corporation and its Subsidiaries).
Without limiting the generality of the foregoing, all vacation, holiday,
sickness and personal days accrued by the employees of the Company and REI
Barbados shall be honored. For a period of at least two years after the
Effective Time (or for such longer or shorter period as is permitted or required
by applicable statute), the Parent will cause the Surviving Corporation to
provide for the benefit of individuals who, immediately prior to the Effective
Time, are former employees of the Company and REI Barbados with benefits that
are substantially equivalent, in the aggregate, to the benefits that are
provided to them immediately prior to the Effective Time under Company Benefit
Plans. In the event that any employee of the Surviving Corporation or one of its
Subsidiaries is at any time after the Effective Time transferred to the Parent
or any affiliate of the Parent (other than the Surviving Corporation and its
Subsidiaries) or becomes a participant in an employee benefit plan, program or
arrangement maintained by or contributed by the Parent or any affiliate of the
Parent (other than the Surviving Corporation and its Subsidiaries), the Parent
shall cause such plan, program or arrangement to treat the prior service of such
employee with the Company and REI Barbados prior to the Effective Time, to the
extent prior service is generally recognized under such plan, program or
arrangement of the Company, as service rendered to the Parent or such affiliates
for purposes of eligibility, vesting or entitlement to benefits under such
plans, program or arrangement (reduced, however, to avoid duplication of
benefits for the same period of service). The Parent shall cause to be waived
any pre-existing condition limitation under its benefit plans that might
otherwise apply to such employee or, to the extent applicable, a former
employee. The Parent agrees to recognize (or cause to be recognized) the dollar
amount of all expenses incurred by such employees or, to the extent applicable,
former employees, during the calendar year in which the Effective Time occurs
for purposes of satisfying the calendar year deductibles and co-payment
limitations for such year under the relevant benefit plans of the Parent and
their respective Subsidiaries.

               (b)  The Parent represents that its current intent is to cause
the Surviving Corporation to maintain its principal production facility in the
Minneapolis, Minnesota metropolitan area for a period of at least two years
after the Effective Time.

               (c)  With respect to the employees of the Company and REI
Barbados set forth on Section 7.10(c) of the Company Disclosure Letter, the
Parent will cause the Surviving Corporation to maintain and fund the Company's
incentive bonus plan as in effect on the date hereof (the "Current Plan")
through the performance period ending December 31, 1999. For the performance
period ending December 31, 1999, the portion of such bonuses that are based on
the Company's operating income (the "Company Performance Component") shall not
be less than 80% of the maximum amount of the Company Performance Component as
described in such plan. If an employee is terminated without cause prior to
<PAGE>

December 31, 1999, such employee shall be paid such bonus in an amount pro rated
according to the period of the employee's service to the Company during 1999.
Effective January 1, 2000, the Current Plan shall terminate, and the employees
of the Company and REI Barbados set forth on Schedule 7.10(c) shall commence to
participate in the Parent's incentive bonus plan (the "Parent Plan") and shall
be entitled to an award from the Parent Plan which reflects (i) the actual
period of participation of such employees in the Parent Plan and (ii) the actual
performance of the applicable business unit during such period.

          SECTION 7.11.  Confidentiality Agreement.  The Company hereby waives
the provisions of the Confidentiality Agreement as and to the extent necessary
to permit the consummation of the transactions contemplated hereby. Upon
acceptance of the shares of Company Common Stock pursuant to the Offer, the
Confidentiality Agreement shall be deemed to have terminated without further
action by the parties hereto.

          SECTION 10.6.  Miscellaneous.

               (a)  This Agreement, together with the exhibit hereto, the
Company Disclosure Letter, the Confidentiality Agreement, the Ancillary
Documents and the Tender and Option Agreement, constitutes the entire agreement,
and supersedes all other prior agreements and understandings, both written and
oral, between the parties with respect to the subject matter hereof and thereof.

               (b)  This Agreement, except for the provisions of Article II and
Section 7.3, is not intended to and shall not confer upon any person other than
the parties hereto any rights or remedies hereunder or by reason hereof.

               (c)  This Agreement shall not, nor shall any of the rights or
interests hereunder, be assigned by any party hereto or be assignable by
operation of law or otherwise without the prior written consent of the other
parties; provided, however, that either the Parent or Merger Sub (or both) may
assign its rights hereunder (including, without limitation, the right to make
the Offer and/or purchase shares of Company Common Stock in the Offer) to an
affiliate, but nothing shall relieve the assignor from its obligations
hereunder. Subject to the preceding sentence, this Agreement shall be binding
upon and shall inure to the benefit to the parties hereto and their respective
successors and assigns.

               (d)  The headings contained in this Agreement are for reference

          SECTION 10.7  Severability.  Any term or provision of this Agreement
which is invalid or unenforceable in any jurisdiction shall, as to that
jurisdiction, be ineffective to the extent of such invalidity or
unenforceability without rendering invalid or unenforceable the remaining terms
and provisions of this Agreement or affecting the validity or enforceability of
any of the terms or provisions of this Agreement in any other jurisdiction. If
any provision of this Agreement is so broad as to be unenforceable, the
provision shall be interpreted to be only so broad as is enforceable.

          SECTION 10.8.  Enforcement of Agreement.  The parties hereto agree
that irreparable damage would occur in the event that any of the provisions of
this Agreement were not performed in accordance with its specific terms or were
otherwise breached. It is accordingly agreed that the parties shall be entitled
to an injunction or injunctions to prevent breaches of this Agreement and to
enforce specifically the terms and provisions hereof in any court, this being in
addition to any other remedy to which they are entitled at law or in equity.

          IN WITNESS WHEREOF, the parties hereto have caused this Agreement to
be duly executed and delivered as of the date first above written.

          EXHIBIT A

          CONDITIONS OF THE OFFER

               Notwithstanding any other term of the Offer or this Agreement,
Merger Sub shall not be required to accept for payment or pay for, subject to
any applicable rules and regulations of the SEC, including Rule 14e-l(c) of the
Exchange Act, any shares of Company Common Stock not theretofore accepted for
payment or paid for and may terminate or amend the Offer as to such shares of
Company Common Stock unless (i) there shall have been validly tendered and not
withdrawn prior to the expiration of the Offer that number of shares of Company
Common Stock which would represent at least a majority of the outstanding shares
of Company Common Stock on a fully diluted basis (the "Minimum Condition") and
(ii) any waiting period under the HSR Act applicable to the purchase of shares
of Company Common Stock pursuant to the Offer shall have expired or been
terminated. Furthermore, notwithstanding any other term of the Offer or this
Agreement, Merger Sub shall not be required to accept for payment or, subject as
aforesaid, to pay for any shares of Company Common Stock not theretofore
accepted for payment or paid for, and may terminate or amend the Offer if at any
time on or after the date of this Agreement and before the acceptance of such
shares of Company Common Stock for payment or the payment therefor, any of the
following conditions exist or shall occur and remain in effect at the scheduled
expiration of the Offer:

                    (a) there shall have been instituted or pending any
litigation before any court or other Governmental Entity which seeks to or, if
successful, would (i) challenge or restrict the acquisition by the Parent or
Merger Sub (or any of its affiliates) of shares of Company Common Stock pursuant
to the Offer or the Merger, restrain, prohibit or delay the making or
consummation of the Offer or the Merger, or obtain any damages in connection
therewith, (ii) make the purchase of or payment for some or all of the shares of
Company Common Stock pursuant to the Offer or the Merger illegal or otherwise
restrict or prohibit consummation of the Offer or the Merger, (iii) impose
limitations on the ability of the Parent or Merger Sub (or any of their
affiliates) effectively to acquire, operate or hold, or require the Parent,
Merger Sub or Company or any of their respective affiliates or Subsidiaries to
dispose of or hold separate, any portion of the assets or the business of any
one of them or their Subsidiaries or affiliates, (iv) impose limitations on the
ability of the Parent, Merger Sub or their affiliates to exercise full rights of
ownership of the shares of Company Common Stock acquired by it pursuant to the
Offer or the Merger, including, without limitation, the right to vote the shares
acquired by it on all matters properly presented to the shareholders of the
Company, (v) restrict any future business activity by the Parent, Merger Sub,
the Company or any of their affiliates, including, without limitation, requiring
the prior consent of any person or entity (including any Governmental Entity) to
future transactions by the Parent, Merger Sub, the Company or any of their
affiliates, or (vi) otherwise affect the Parent, Merger Sub, the Company or any
of their respective affiliates, which, in each such case described in (i)
through (vi), is reasonably likely to have a Company Material Adverse Effect or
a Parent Material Adverse Effect or otherwise make consummation of the Offer or
the Merger unduly burdensome; or

                    (b) there shall have been promulgated, enacted, entered,
enforced or deemed applicable to the Offer or the Merger, by any Governmental
<PAGE>

Entity, any Law (other than the HSR Act) that is reasonably likely to result in
any of the consequences referred to in subsection (a) above; or

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

                    (d) (i) any of the representations and warranties made by
the Company in this Agreement or in any Ancillary Document (which for purposes
of this clause (d) shall be read as though none of them contained any Material
Adverse Effect or materiality qualifications) shall not have been true and
correct in all respects when made, or shall thereafter have ceased to be true
and correct in all respects as if made as of such later date (other than
representations and warranties made as of a specified date), except where the
failure of the representations and warranties to be true and correct in all
respects would not in the aggregate have a Company Material Adverse Effect, or
(ii) the Company shall have breached or failed to comply in any material respect
with any of its obligations under this Agreement; or

                    (e) the Board of Directors shall have modified or amended
its recommendation of the Offer or the Merger in any manner adverse to the
Parent or Merger Sub or shall have withdrawn or failed to confirm within five
business days of the Parent's request therefor its recommendation of the Offer
or the Merger or shall have recommended acceptance of any Acquisition Proposal
or shall have resolved to do any of the foregoing; or

                    (f) any change, new event or development shall have occurred
or be threatened which, either individually or in the aggregate, would or is
likely in the future to have a Company Material Adverse Effect, other than
changes in general economic, financial, regulatory, political or market
conditions.

          The foregoing conditions are for the sole benefit of the Parent and
Merger Sub and may be asserted by the Parent or Merger Sub with respect to the
consummation of the Offer regardless of the circumstances giving rise to any
such condition (other than any action or inaction by the Parent or Merger Sub)
and may be waived by the Parent or Merger Sub, in whole or in part, at any time
and from time to time, in the reasonable discretion of the Parent subject to the
terms of the Agreement.  The failure by the Parent or Merger Sub at any time to
exercise any of the foregoing rights will 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 will 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 of Company Common Stock not theretofore accepted for payment
shall forthwith be returned by the Paying Agent to the tendering shareholders.

          WHEREAS, each Stockholder is the beneficial owner of the shares of
Company Common Stock, Options, Warrants, and Rights set forth opposite such
Stockholder's name on Schedule A hereto (collectively referred to herein as the
"Securities" of such Stockholder; such Securities, as such Securities may be
 ----------
adjusted by stock dividend, stock split, recapitalization, combination or
exchange of shares, merger, consolidation, reorganization or other change or
transaction of or by the Company, together with shares of Company Common Stock
issuable upon the exercise of Options, Warrants, and shares of Company Common
Stock issuable upon the exercise of Rights being referred to herein as the

 ------

          WHEREAS, as a condition to each of Purchaser and Merger Sub's
willingness to enter into the Merger Agreement, Purchaser and Merger Sub have
requested that the Stockholders enter into, and the Stockholders have agreed to
enter into, this Agreement;

          NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth herein, the
parties agree as follows:

     Section 1.  Certain Definitions.  Capitalized terms used but not otherwise
                 -------------------
defined herein have the meanings ascribed to such terms in the Merger Agreement.

     Section 2.  Representations and Warranties of the Stockholders.  Each
                 --------------------------------------------------
Stockholder, severally and not jointly, represents and warrants to Purchaser and
Merger Sub, as of the date hereof and as of the Closing (as defined below), as
follows:
<PAGE>

          (a)  The Stockholder is the beneficial owner (as defined in Rule 13d-3
under the Exchange Act) of, and has good title to, all of the Securities set
forth opposite such Stockholder's name on Schedule A, free and clear of any
                                          ----------
pledge, hypothecation, claim, security interest, charge, encumbrance, voting
trust agreement, interest, option, lien, charge or similar restriction or
limitation, including any restriction on the right to vote, sell or otherwise
dispose of the Securities, other than those arising under the federal and state
securities laws (each, a "Lien"), except as set forth in this Agreement.
                          ----

          (b)  The Securities constitute all of the securities (as defined in
Section 3(a)(10) of the Exchange Act) of the Company beneficially owned,
directly or indirectly, by the Stockholder.

          (c)  Except for the Securities, the Stockholder does not, directly or
indirectly, beneficially own or have any option, warrant or other right to
acquire any securities of the Company that are or may by their terms become
entitled to vote or any securities that are convertible or exchangeable into or
exercisable for any securities of the Company that are or may by their terms
become entitled to vote, nor is the Stockholder subject to any contract,
commitment, arrangement, understanding, restriction or relationship (whether or
not legally enforceable), other than this Agreement, that provides for such
Stockholder to vote or acquire any securities of the Company.  The Stockholder
holds exclusive power to vote the Company Common Stock set forth opposite its
name on Schedule A, if any, and has not granted a proxy to any other person to
vote any Company Common Stock (including those issuable upon exercise of the
Options, Warrants or Rights), subject to the limitations set forth in this
Agreement.

          (d)  This Agreement has been duly executed and delivered by the
Stockholder, and assuming the due authorization, execution and delivery thereof
by the other parties hereto, constitutes the legal, valid and binding obligation
of the Stockholder, enforceable against the Stockholder in accordance with its
terms, except as enforcement against the Stockholder may be limited by
bankruptcy, insolvency, moratorium or other similar laws relating to creditors
rights generally and by general equitable principles (regardless of whether such
enforceability is considered in a proceeding in equity or at law).

          (e)  Neither the execution and delivery of this Agreement nor the
performance by the Stockholder of the Stockholder's obligations hereunder will
conflict with, result in a violation or breach of, or constitute a default (or
an event that, with notice or lapse of time or both, would result in a default)
or give rise to any right of termination, amendment, cancellation, or
acceleration or result in the creation of any Lien on any Shares under, (i) any
contract, commitment, agreement, understanding, arrangement or restriction of
any kind to which the Stockholder is a party or by which the Stockholder is
bound or (ii) any injunction, judgment, writ, decree, order or ruling applicable
to the Stockholder, except for conflicts, violations, breaches, defaults,
terminations, amendments, cancellations, accelerations or Liens that would not
individually or in the aggregate be expected
<PAGE>

to prevent or materially impair or delay the consummation by such Stockholder of
the transactions contemplated hereby.

          (f)  Neither the execution and delivery of this Agreement nor the
performance by the Stockholder of the Stockholder's obligations hereunder will
(i) violate any Law applicable to the Stockholder or require any order, consent,
authorization or approval of, filing or registration with, or declaration or
notice to, any court, administrative agency or other governmental body or
authority, other than any required notices or filings pursuant to the HSR Act,
foreign antitrust or competition laws or the federal securities laws, or (ii) if
the Stockholder is not a natural person, conflict with or violate the articles
of incorporation or bylaws or equivalent organizational documents of such
Stockholder.

          (g)  No investment banker, broker, finder or other intermediary is, or
will be, entitled to a fee or commission from Merger Sub, Purchaser or the
Company in respect of this Agreement based on any arrangement or agreement made
by or on behalf of such Stockholder in this Agreement or otherwise in his or her
capacity as a stockholder of the Company.

          (h)  The Stockholder understands and acknowledges that Purchaser is
entering into, and causing Merger Sub to enter into, the Merger Agreement in
reliance upon the Stockholder's execution and delivery of this Agreement.

          (i)  If the Stockholder is not a natural person, such Stockholder is a
corporation, partnership or other legal entity duly incorporated or organized,
validly existing and in good standing under the laws of the jurisdiction of its
incorporation or organization.

          (j)  If the Stockholder is not a natural person, (i) such Stockholder
has all necessary corporate or partnership power and authority to execute and
deliver this Agreement, to perform its obligations hereunder and to consummate
the transactions contemplated hereunder, and (ii) the execution and delivery of
this Agreement by such Stockholder and the consummation by such Stockholder of
the transactions contemplated hereunder have been duly and validly authorized by
all necessary corporate or other action and no other corporate or other
proceedings on the part of such Stockholder are necessary to authorize this
Agreement or to consummate the transactions contemplated hereunder.

     Section 3.  Representations and Warranties of Purchaser and Merger Sub.
                 ----------------------------------------------------------
Purchaser and Merger Sub hereby make each of the representations and warranties
contained in Sections 5.1, 5.3 and 5.4 of the Merger Agreement, as if such
representations and warranties were set forth herein.

     Section 4.  Transfer of the Shares.  During the term of this Agreement,
                 ----------------------
except as otherwise expressly provided herein, each Stockholder agrees that such
Stockholder will not (a) tender into any tender or exchange offer or otherwise
sell,

                                      -3-
<PAGE>

transfer, pledge, assign, hypothecate or otherwise dispose of (including by
operation of Law), or create any Lien on, any of the Shares, (b) deposit the
Shares into a voting trust, enter into a voting agreement or arrangement with
respect to the Shares or grant any proxy or power of attorney with respect to
the Shares, (c) enter into any contract, option or other arrangement (including
any profit sharing arrangement) or undertaking with respect to the direct or
indirect acquisition or sale, transfer, pledge, assignment, hypothecation or
other disposition of any interest in or the voting of any Shares or any other
securities of the Company, (d) exercise any rights (including, without
limitation, under Section 302A.473 of the Minnesota Business Corporation Act) to
demand appraisal of any Shares which may arise with respect to the Merger, or
(e) take any other action that would in any way restrict, limit or interfere
with the performance of such Stockholder's obligations hereunder or the
transactions contemplated hereby or which would otherwise diminish the benefits
of this Agreement to Purchaser or Merger Sub.

     Section 5.  Adjustments.  (a)  In the event (i) of any stock dividend,
                 -----------
stock split, recapitalization, reclassification, combination or exchange of
shares of capital stock or other securities of the Company on, of or affecting
the Shares or the like or any other action that would have the effect of
changing a Stockholder's ownership of the Company's capital stock or other
securities or (ii) a Stockholder becomes the beneficial owner of any additional
Shares of or other securities of the Company, then the terms of this Agreement
will apply to the shares of capital stock and other securities of the Company
held by such Stockholder immediately following the effectiveness of the events
described in clause (i) or such Stockholder becoming the beneficial owner
thereof, as described in clause (ii), as though they were Shares hereunder.

          (b)  Each Stockholder hereby agrees, while this Agreement is in
effect, to promptly notify Purchaser and Merger Sub of the number of any new
Shares acquired by such Stockholder, if any, after the date hereof.

     Section 6.  Tender of Shares of Company Common Stock.  Each Stockholder
                 ----------------------------------------
hereby agrees that such Stockholder will validly tender (or cause the record
owner of such shares to validly tender) and sell (and not withdraw, except in
the event the Purchase Option is exercised, in which case such withdrawal shall
be for the limited purpose of consummating the Purchase Option) pursuant to and
in accordance with the terms of the Offer not later than the fifth business day
after commencement of the Offer (or the earlier of the expiration date of the
Offer and the fifth business day after such shares of Company Common Stock are
acquired by such Stockholder if the Stockholder acquires shares of Company
Common Stock after the date hereof), or, if the Stockholder has not received the
Offer Documents by such time, within two business days following receipt of such
documents, all of the then outstanding shares of Company Common Stock
beneficially owned by such Stockholder (including the shares of Company Common
Stock outstanding as of the date hereof and shares of Company Common Stock
issued following the exercise (if any) of the Options, Warrants, and Rights, in
each case as set forth on Schedule A hereto opposite such Stockholder's name).
Upon the purchase by Purchaser or Merger Sub of all of such then outstanding
<PAGE>

shares of Company Common Stock beneficially owned by such Stockholder pursuant
to the Offer in accordance with this Section 6, this Agreement will terminate as
it relates to such Stockholder. In the event, notwithstanding the provisions of
the first sentence of this Section 6, any shares of Company Common Stock
beneficially owned by a Stockholder are for any reason withdrawn from the Offer
or are not purchased pursuant to the Offer, such shares of Company Common Stock
will remain subject to the terms of this Agreement.  Each Stockholder
acknowledges that Purchaser's obligation to accept for payment and pay for the
shares of Company Common Stock tendered in the Offer is subject to all the terms
and conditions of the Offer.

     Section 7.  Voting Agreement.  Each Stockholder, by this Agreement, does
                 ----------------
hereby (a) agree to appear (or not appear, if requested by Purchaser or Merger
Sub) at any annual, special, postponed or adjourned meeting of the stockholders
of the Company or otherwise cause the shares of Company Common Stock such
Stockholder beneficially owns to be counted as present (or absent, if requested
by Purchaser or Merger Sub) thereat for purposes of establishing a quorum and to
vote or consent, and (b) constitute and appoint Purchaser and Merger Sub, or any
nominee thereof, with full power of substitution, during and for the term of
this Agreement, as his true and lawful attorney and proxy for and in his name,
place and stead, to vote all the shares of Company Common Stock such Stockholder
beneficially owns at the time of such vote, at any annual, special, postponed or
adjourned meeting of the stockholders of the Company (and this appointment will
include the right to sign his or its name (as stockholder) to any consent,
certificate or other document relating to the Company that the laws of the State
of Minnesota may require or permit), in the case of both (a) and (b) above, (x)
in favor of approval and adoption of the Merger Agreement and approval and
adoption of the Merger and the other transactions contemplated thereby and (y)
against (1) any Acquisition Proposal (other than the Merger and the other
transactions contemplated thereby), (2) any action or agreement that would
result in a breach in any respect of any covenant, agreement, representation or
warranty of the Company under the Merger Agreement and (3) any other action that
is intended, or could be expected, to impede, interfere with, delay, postpone,
or adversely affect the Offer, the Merger and the other transactions
contemplated by this Agreement, the Merger Agreement and the Ancillary
Documents. This proxy and power of attorney is a proxy and power coupled with an
interest, and each Stockholder declares that it is irrevocable until this
Agreement shall terminate in accordance with its terms. Each Stockholder hereby
revokes all and any other proxies with respect to the Shares that such
Stockholder may have heretofore made or granted. For shares of Company Common
Stock as to which a Stockholder is the beneficial but not the record owner, such
Stockholder shall use his or its best efforts to cause any record owner of such
Shares to grant to Purchaser a proxy to the same effect as that contained
herein. Each Stockholder hereby agrees to permit Purchaser and Merger Sub to
publish and disclose in the Offer Documents and the Proxy Statement and related
filings under the securities laws such Stockholder's identity

                                      -5-
<PAGE>

and ownership of Shares and the nature of his or its commitments, arrangements
and understandings under this Agreement.

     Section 8.  No Solicitation.  Each Stockholder agrees that neither such
                 ---------------
Stockholder nor any of such Stockholder's officers, directors, employees,
trustees, representatives, agents or affiliates (including, without limitation,
any investment banker, attorney or accountant retained by any of them) will
directly or indirectly initiate, solicit or encourage (including by way of
furnishing non-public information or assistance), or take any other action to
facilitate, any inquiries or the making or submission of any Acquisition
Proposal, or enter into or maintain or continue discussions or negotiate with
any person or entity in furtherance of such inquiries or to obtain or induce any
person to make or submit an Acquisition Proposal or agree to or endorse any
Acquisition Proposal or assist or participate in, facilitate or encourage, any
effort or attempt by any other person or entity to do or seek any of the
foregoing or authorize or permit any of its officers, directors, employees,
trustees or any of its affiliates or any investment banker, financial advisor,
attorney, accountant or other representative or agent retained by any of them to
take any such action. Each Stockholder shall promptly advise Purchaser in
writing of the receipt of request for information or any inquiries or proposals
relating to an Acquisition Proposal.

     Section 9.  Grant of Purchase Option.  The Stockholder hereby grants to
                 ------------------------
Purchaser and Merger Sub an irrevocable option (the "Purchase Option") to
                                                     ---------------
purchase for cash at a price (the "Exercise Price") set forth below, in a manner
                                   --------------
set forth below, any or all of the Shares (and including Shares acquired after
the date hereof by such Stockholder) beneficially owned by the Stockholder.  The
Exercise Price for shares of Company Common Stock shall be equal to the Merger
Consideration. The Exercise Price as it relates to the Options and Warrants
shall be an amount in cash equal to the excess, if any, of the Merger
Consideration over the per share exercise price of such Option or Warrant,
without interest.  To the extent that the per share exercise or conversion price
of any Option or Warrant exceeds the Merger Consideration, such Option or
Warrant shall be canceled and the Stockholder shall not receive or be entitled
to receive any consideration from Purchaser, Merger Sub or the Company relating
thereto.  The Rights associated with any shares of Company Common Stock
transferred pursuant to this Agreement will be transferred with such shares of
Company Common Stock without payment of any additional consideration therefor.
In the event of any stock dividends, stock splits, recapitalizations,
combinations, exchanges of shares or the like, the Exercise Price will be
appropriately adjusted for the purpose of this Section 9.  The amount payable
pursuant to this Section 9 shall be subject to all applicable withholding taxes.

     Section 10. Exercise of Purchase Option.
                 ---------------------------

          (a)  Subject to the conditions set forth in Section 12 hereof, the
Purchase Option may be exercised by Purchaser or Merger Sub, in whole or in
part, at any time or from time to time after the occurrence of any Trigger Event
(as defined below).  Each Stockholder shall notify Purchaser promptly in writing
of
<PAGE>

the occurrence of any Trigger Event, it being understood that the giving of
such notice by the Stockholder is not a condition to the right of Purchaser or
Merger Sub to exercise the Purchase Option. In the event Purchaser or Merger Sub
wishes to exercise the Purchase Option, Purchaser shall deliver to each
Stockholder a written notice (an "Exercise Notice") specifying the total number
                                  ---------------
of Shares it wishes to purchase from such Stockholder. Each closing of a
purchase of Shares (a "Closing") will occur at a place, on a date and at a time
                       -------
designated by Purchaser or Merger Sub in an Exercise Notice delivered at least
two business days prior to the date of the Closing.

          (b)  A "Trigger Event" means any one of the following: (i) the Merger
                  -------------
Agreement becomes terminable under circumstances that entitle Purchaser or
Merger Sub to receive the Termination Fee under Section 9.3 of the Merger
Agreement (regardless of whether the Merger Agreement is actually terminated and
whether such Termination Fee is then actually paid) or (ii) the Offer is
consummated but, due to the failure of the Stockholder to validly tender and not
withdraw all of the then outstanding shares of Company Common Stock beneficially
owned by such Stockholder, the Purchaser has not accepted for payment or paid
for all of such shares of Company Common Stock.

          (c)  If requested by Purchaser and Merger Sub in the Exercise Notice,
such Stockholder shall exercise and/or convert all Options and Warrants (to the
extent exercisable and convertible) and other rights (including conversion or
exchange rights), other than Options and Warrants with exercise or conversion
prices above the Merger Consideration, beneficially owned by such Stockholder,
and shall, if directed by Purchaser and Merger Sub, tender the shares of Company
Common Stock acquired pursuant to such exercise or conversion into the Offer or
sell such shares of Company Common Stock to Purchaser or Merger Sub as provided
in this Agreement.

          (d) In the event that, within 12 months of the exercise of the
Purchase Option, Purchaser sells, to a third party which is not an affiliate of
Purchaser, Shares acquired by means of exercise of the Purchase Option
("Exercise Shares") for an aggregate consideration (the "Aggregate
  ---------------                                        ---------
Consideration") greater than the aggregate Exercise Price (the "Aggregate
- -------------                                                   ---------
Exercise Price") paid for such Shares, Purchaser agrees to pay to the
- --------------
Stockholders an amount equal to the excess of the Aggregate Consideration over
the Aggregate Exercise Price.  Each Stockholder shall be entitled to the
proportion of such excess equal to proportion of the total number of Exercise
Shares which were acquired from such Stockholder.  In addition, in the event
that, within 12 months of the exercise of the Purchase Option, Purchaser shall
consummate a merger agreement with the Company, or shall purchase Shares
pursuant to a tender offer for all Shares, at a price per share (taking into
account any stock dividends, stock splits, recapitalizations, combinations,
exchanges of shares or the like or any other action that would have the effect
of changing Purchaser's ownership of the Company's

                                      -7-
<PAGE>

capital stock or other securities) in excess of the Exercise Price, Purchaser
agrees to pay each Stockholder such excess for each Exercise Share purchased
from such Stockholder.

     Section 11.  Termination. This Agreement will terminate (a) pursuant to
                  -----------
Section 6 or (b) upon the earliest of: (i) the Effective Time; (ii) termination
of the Merger Agreement in accordance with its terms other than upon, during the
continuance of, or after, a Trigger Event or an event which could lead to a
Trigger Event; or (iii) 120 days following any termination of the Merger
Agreement upon, during the continuance of or after a Trigger Event (or if, at
the expiration of such 120 day period the Purchase Option cannot be exercised by
reason of any applicable judgment, decree, order, injunction, law or regulation,
10 business days after such impediment to exercise has been removed or has
become final and not subject to appeal). Upon the giving by Purchaser or Merger
Sub to the Stockholder of the Exercise Notice and the tender of the aggregate
Exercise Price, Purchaser or Merger Sub, as the case may be, will be deemed to
be the holder of record of the Shares transferable upon such exercise,
notwithstanding that the stock transfer books of the Company are then closed or
that certificates representing such Shares have not been actually delivered to
Purchaser. Notwithstanding the termination of this Agreement, Purchaser will be
entitled to purchase the Shares subject to the Purchase Option if it has
exercised the Purchase Option in accordance with the terms hereof prior to the
termination of this Agreement and the termination of this Agreement will not
affect any rights hereunder which by their terms do not terminate or expire
prior to or as of such termination.

     Section 12.  Conditions To Closing.  The obligation of each Stockholder to
                  ---------------------
sell such Stockholder's Shares to Purchaser or Merger Sub hereunder is subject
to the conditions that (i) all waiting periods, if any, under the HSR Act,
applicable to the sale of the Shares or the acquisition of the Shares by
Purchaser or Merger Sub, as the case may be, hereunder have expired or have been
terminated; (ii) all consents, approvals, orders or authorizations of, or
registrations, declarations or filings with, any court, administrative agency or
other Governmental Entity, if any, required in connection with the sale of the
Shares or the acquisition of the Shares by Purchaser or Merger Sub hereunder
have been obtained or made; and (iii) no preliminary or permanent injunction or
other order by any court of competent jurisdiction prohibiting or otherwise
restraining such sale or acquisition is in effect.

     Section 13.  Closing.  At any Closing with respect to Shares beneficially
                  -------
owned by a Stockholder, (a) such Stockholder will deliver to Purchaser, Merger
Sub or their respective designee a certificate or certificates in definitive
form representing the number of the Shares designated by Purchaser or Merger
Sub, as the case may be, in its Exercise Notice, such certificate to be
registered in the name of Purchaser, Merger Sub or their respective designee and
(b) Purchaser or Merger Sub, as the case may be, will deliver to the Stockholder
the aggregate Exercise Price for the Shares so designated and being purchased by
wire transfer of immediately available funds.

hereof. The covenants and agreements made herein will survive in accordance with
their respective terms.

     Section 15.  Expenses.  Except as otherwise provided in the Merger
                  --------
Agreement, all costs and expenses incurred in connection with this Agreement
shall be paid by the party incurring such expenses.

                  ------------
counterparts, all of which shall be considered the same agreement.

     Section 17.  Governing Law.  This Agreement shall be governed by and
                  -------------
construed in accordance with the laws of the State of Minnesota, without regard
to principles of conflicts of laws thereof.

                                      -9-
<PAGE>

          (a) This Agreement shall not, nor shall any of the rights or interests
hereunder, be assigned by any party hereto or assignable by operation of law or
otherwise without the prior written consent of the other parties hereto;
provided, however, that Purchaser may assign its rights hereunder to an
affiliate, but nothing shall relieve the assignor from its obligations
hereunder. Subject to the preceding sentence, this Agreement shall be binding
upon and shall inure to the benefit to the parties hereto and their respective
successors and assigns.

          (b) The headings contained in this Agreement are for reference
purposes and shall not affect in any way the meaning or interpretation of this
Agreement. In this Agreement, unless the context otherwise requires, words
describing the singular number shall include the plural and vice versa, and
words denoting any gender shall include all genders and words denoting natural
persons shall include corporations and partnerships and vice versa. Whenever the
words "include," "includes" or "including" are used in this Agreement, they
shall be understood to be followed by the words "without limitation."

          (c) All rights, powers and remedies provided under this Agreement or
otherwise available in respect hereof at law or in equity will be cumulative and
not alternative, and the exercise of any thereof by either party will not
preclude the simultaneous or later exercise of any other such right, power or
remedy by such party.

     Section 20.  Severability.  Any term or provision of this Agreement which
                  ------------
is invalid or unenforceable in any jurisdiction shall, as to that jurisdiction,
be ineffective to the extent of such invalidity or unenforceability without
rendering invalid or unenforceable the remaining terms and provisions of this
Agreement or affecting the validity or unenforceability of any of the terms or
provisions of this Agreement in any other jurisdiction.  If any provision of
this Agreement is so broad as to be unenforceable, the provision shall be
interpreted to be only so broad as is enforceable.

     Section 21.  Enforcement of Agreement; Waiver of Jury Trial.  (a)  The
                  ----------------------------------------------
parties hereto agree that irreparable damage would occur in the event that any
of the provisions of this Agreement were not performed in accordance with its
specific terms or was otherwise breached.  It is accordingly agreed that the
parties shall be entitled to an injunction or injunctions to prevent breaches of
this Agreement and to enforce specifically the terms and provisions hereof in
any court, this being in addition to any other remedy to which they are entitled
at law or in equity.

                  (b)  Each of the parties irrevocably and unconditionally
waives, to the fullest extent permitted by applicable law, any and all rights to
trial by jury in connection with any litigation arising out of or relating to
this Agreement.

     Section 22.  Waiver, Etc.  Any provision of this Agreement may be waived at
                  -----------
any time by the party that is entitled to the benefits thereof. No such
<PAGE>

waiver, amendment or supplement will be effective unless in writing and signed
by the party or parties sought to be bound thereby. Any waiver by any party of a
breach of any provision of this Agreement will not operate as or be construed to
be a waiver of any other breach of such provision or of any breach of any other
provision of this Agreement. The failure of a party to insist upon strict
adherence to any term of this Agreement or one or more sections hereof will not
be considered a waiver or deprive that party of the right thereafter to insist
upon strict adherence to that term or any other term of this Agreement.

     Section 23.  Amendment.  This Agreement may not be amended, except by an
                  ----------
instrument in writing signed on behalf of each of the parties.

     Section 24.  Further Assurances.  (a)  Each party hereto will execute and
                  ------------------
deliver all other documents and instruments and take all other actions that may
be reasonably necessary in order to consummate the transactions provided for by
such exercise.

              (b)  Each of the Stockholders will execute and deliver all
documents and instruments and take all other actions that may be reasonably
necessary to permit the Purchaser to exercise all rights granted to the
Purchaser by such Stockholder and obtain all benefits contemplated under this
Agreement with respect to the rights granted by such Stockholder.

     Section 25.  Publicity.  A Stockholder shall not issue any press release or
                  ---------
otherwise make any public statements with respect to this Agreement or the
Merger Agreement or the other transactions contemplated hereby or thereby
without the consent of Purchaser and Merger Sub; provided, however, that a
Stockholder may, without the prior consent of Purchaser and Merger Sub, issue a
press release or otherwise make such public statement as may be required by Law
if it has used all reasonable efforts to consult with Purchaser and Merger Sub
and to obtain Purchaser and Merger Sub's consent but has been unable to do so in
a timely manner.

     Section 26.  Stockholder Capacity.  No person executing this Agreement
                  --------------------
makes any agreement or understanding herein in such Stockholder's capacity as a
director or officer of the Company. Each Stockholder signs solely in such
Stockholder's capacity as the beneficial owner of such Stockholder's Shares and
nothing herein shall limit or affect any actions taken by a Stockholder in such
Stockholder's capacity as an officer or director of the Company to the extent
specifically permitted by the Merger Agreement.

     Section 27.  Lien. (a) Brian F. Sullivan ("Sullivan") represents that the
                  ----
shares of Company Common Stock set forth opposite his name on Schedule A are
subject to Liens as described in Schedule B. Sullivan agrees that (i) by 5:00

Lien. Sullivan agrees that he will not permit the holder of such Lien to obtain
any rights in the shares of Company Common Stock, including by foreclosure, and
will take all actions necessary or advisable to prevent such holder from
obtaining such rights.

          (b) William F. Wanner, Jr. and WEC, Inc., jointly and severally
represent that the shares of Company Common Stock set forth opposite their
respective names on Schedule A are subject to Liens as described in Schedule B.
Wanner and WEC, Inc. agree that (i) by 5:00 p.m. on August 27, 1999, 80% of such
shares (in the aggregate) will no longer be subject to such Lien or any other
Lien and (ii) by 5:00 p.m. on September 1, 1999, no such shares will be subject
to such Lien or any other Lien. Wanner and WEC, Inc. agree that he will not
permit the holder of such Lien to obtain any rights in the shares of Company
Common Stock, including by foreclosure, and will take all actions necessary or
advisable to prevent such holder from obtaining such rights.

     Section 27.  Enforcement of Agreement.  The parties hereto agree that
                  ------------------------
irreparable damage would occur in the event that any of the provisions of this
Agreement were not performed in accordance with its specific terms or were
otherwise breached. It is accordingly agreed that the parties shall be entitled
to an injunction or injunctions to prevent breaches of this Agreement and to
enforce specifically the terms and provisions hereof in any court, this being in
addition to any other remedy to which they are entitled at law or in equity.

set forth in the Offer Documents and all the other conditions to the Merger are
satisfied or waived, the Merger of Merger Sub with and into the Company with the
Company as the surviving corporation in the Merger, pursuant to which the
Company will become a wholly owned subsidiary of Grantee; and

     WHEREAS, as a condition and inducement to each of Grantee's and Merger
Sub's willingness to enter into the Merger Agreement, Grantee has requested that
the Company agree, and the Company has agreed, to grant Grantee the Option (as
defined below).

     NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth herein, the
Company and Grantee agree as follows:

     Section 1.  Grant of Option.  Subject to the terms and conditions set forth
                 ---------------
herein, the Company hereby grants to Grantee an irrevocable option (the

"Option") to purchase up to 1,202,875 (as adjusted as set forth herein) shares
 ------
(the "Option Shares") of Company Common Stock, at a purchase price of $35.25 (as
      -------------
adjusted as set forth herein) per Option Share (the "Purchase Price"); provided,
                                                     --------------    --------
however, that in no event shall the number of Option Shares exceed 19.9% of the
- -------
capital stock entitled to vote generally for the election of directors of the
Company that is issued and outstanding at the time of exercise (without giving
effect to the Option Shares issued or issuable under the Option) (the "Maximum
                                                                       -------
Applicable Percentage").  The number of Option Shares purchasable upon exercise
- ---------------------
of the Option and the Option Price is subject to adjustment as set forth herein
and subject to Section 9(b).

     Section 2.  Exercise of Option.  (a)  Grantee may exercise the Option, with
                 ------------------
respect to any or all of the Option Shares at any time, subject to the
provisions of Section 2(c), after the occurrence of any event as a result of
which the Grantee is entitled to receive a Termination Fee pursuant to Section
9.3 of the Merger Agreement (a "Purchase
                                --------
<PAGE>

Event") (regardless of whether the Merger Agreement is actually terminated and
- -----
whether such Termination Fee is then actually paid); provided, however, that (i)
                                                     --------  -------
except as provided in the last sentence of this Section 2(a), the Option will
terminate and be of no further force and effect upon the earliest to occur of
(A) the Effective Time, (B) termination of the Merger Agreement in accordance
with its terms other than upon, during the continuance of, or after, a Purchase
Event or an event which could lead to a Purchase Event, and (C) 120 days after
the first occurrence of a Purchase Event, and (ii) any purchase of Option Shares
upon exercise of the Option will be subject to compliance with the HSR Act and
the obtaining or making of any consents, approvals, orders, notifications,
filings, expiration of applicable waiting periods or authorizations, the failure
of which to have obtained or made would have the effect of making the purchase
of Option Shares by Grantee illegal (the "Regulatory Approvals").
                                          --------------------
Notwithstanding the termination of the Option, Grantee will be entitled to
purchase the Option Shares if it has exercised the Option in accordance with the
terms hereof prior to the termination of the Option and the termination of the
Option will not affect any rights hereunder (including, without limitation,
Section 7 hereof) which by their terms do not terminate or expire prior to or as
of such termination.

          (b) In the event that Grantee is required to, or is entitled to and
wishes to exercise the Option, it will send to the Company a written notice (an
"Exercise Notice"; the date of which being herein referred to as the "Notice
 ---------------                                                      ------
Date") to that effect which Exercise Notice also specifies the number of Option
- ----
Shares, if any, Grantee wishes to purchase, the number of Option Shares, if any,
with respect to which Grantee wishes to exercise its Cash-Out Right (as defined
herein) pursuant to Section 7(c), the denominations of the certificate or
certificates evidencing the Option Shares which Grantee wishes to purchase and a
date (an "Option Closing Date"), subject to the following sentence, not later
          -------------------
than 20 business days from the Notice Date for the closing of such purchase (an
"Option Closing").  Any Option Closing will be at an agreed location and time in
 --------------
New York, New York on the applicable Option Closing Date or at such later date
as may be necessary so as to comply with the provisions of Section 2(c).

          (c) Notwithstanding anything to the contrary contained herein, any
exercise of the Option and purchase of Option Shares shall be subject to
compliance with applicable Laws, which may prohibit the purchase of any or all
of the Option Shares specified in the Exercise Notice without first obtaining or
making certain Regulatory Approvals.  In such event, if the Option is otherwise
exercisable and Grantee wishes to exercise the Option, the Option may be
exercised in accordance with Section 2(b) and Grantee shall acquire the maximum
number of Option Shares specified in the Exercise Notice that Grantee is then
permitted to acquire under the applicable Laws, and if Grantee thereafter
obtains the Regulatory Approvals to acquire the remaining balance of the Option
Shares specified in the Exercise Notice, then Grantee shall be entitled to
acquire such remaining balance.  The Company agrees to use its reasonable best
efforts to assist Grantee in seeking the Regulatory Approvals and Grantee agrees
to use its reasonable best efforts to obtain such Regulatory Approvals as
promptly as practicable.

                                      -2-
<PAGE>

          In the event that Grantee exercised the Option and either (i) Grantee
receives official notice that a Regulatory Approval required for the purchase of
any Option Shares will not be issued or granted or (ii) such Regulatory Approval
has not been issued or granted within six months of the date of the Exercise
Notice, then Grantee shall have the right, but not the obligation, to exercise
its Cash-Out Right pursuant to Section 7(c) with respect to the Option Shares
for which such Regulatory Approval will not be issued or granted or has not been
issued or granted.

     Section 3.  Payment and Delivery of Certificates.  (a)  At any Option
                 ------------------------------------
Closing, Grantee will pay to the Company in immediately available funds by wire
transfer to a bank account designated in writing by the Company an amount equal
to the Purchase Price multiplied by the number of Option Shares to be purchased
at such Option Closing.

          (b) At any Option Closing, simultaneously with the delivery of
immediately available funds as provided in Section 3(a), the Company will
deliver to Grantee a certificate or certificates representing the Option Shares
to be purchased at such Option Closing, which Option Shares will be free and
clear of all Liens.  If at the time of issuance of the Option Shares hereunder,
the Company shall have issued any rights or other securities which are attached
to or otherwise associated with the Company Common Stock, then each Option Share
shall also represent such rights or other securities with terms substantially
the same as, and at least as favorable to the Grantee as are provided under any
shareholder rights agreement or similar agreement of the Company then in effect.

          (c) Certificates for the Option Shares delivered at an Option Closing
will have typed or printed thereon a restrictive legend which will read
substantially as follows:

          "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
          REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY
          BE REOFFERED OR SOLD ONLY IF SO REGISTERED OR IF AN EXEMPTION
          FROM SUCH REGISTRATION IS AVAILABLE."

It is understood and agreed that the legend will be removed by delivery of
substitute certificate(s) without such reference if such Option Shares have been
registered pursuant to the Securities Act, such Option Shares have been sold in
reliance on and in accordance with Rule 144 under the Securities Act or Grantee
has delivered to the Company a copy of a letter from the staff of the SEC, or an
opinion of counsel in form and substance reasonably satisfactory to the Company
and its counsel, to the effect that such legend is not required for purposes of
the Securities Act.

     Section 4.  Covenants of the Company.  In addition to its other agreements
                 ------------------------
and covenants herein, the Company agrees:

                                      -3-
<PAGE>

          (a) Shares Reserved for Issuance.  To maintain, free from preemptive
              ----------------------------
rights, sufficient authorized but unissued or treasury shares of Company Common
Stock so that the Option may be fully exercised without additional authorization
of Company Common Stock after giving effect to all other options, warrants,
convertible securities and other rights of third parties to purchase shares of
Company Common Stock from the Company, and to issue the appropriate number of
shares of Company Common Stock pursuant to the terms of this Agreement.

          (b) No Avoidance.  Not to avoid or seek to avoid (whether by charter
              ------------
amendment or through reorganization, consolidation, merger, issuance of rights,
dissolution or sale of assets, or by any other voluntary act) the observance or
performance of any of the covenants, agreements or conditions to be observed or
performed hereunder by the Company.

     Section 5.  Representations and Warranties of the Company.  The Company
                 ---------------------------------------------
hereby represents and warrants to Grantee as follows:

          (a) Merger Agreement.  The Company hereby makes each of the
              ----------------
representations and warranties contained in Sections 4.3, 4.5, 4.6, 4.21 and
4.22 of the Merger Agreement as they relate to the Company and this Agreement,
as if such representations and warranties were set forth herein.

          (b) Authorized Stock.  The Company has taken all necessary corporate
              ----------------
and other action to authorize and reserve and, subject to the expiration or
termination of any required waiting period under the HSR Act, to permit it to
issue, and, at all times from the date hereof until the obligation to deliver
Option Shares upon the exercise of the Option terminates, shall have reserved
for issuance, upon exercise of the Option, shares of Company Common Stock
necessary for Grantee to exercise the Option, and the Company will take all
necessary corporate action to authorize and reserve for issuance all additional
shares of Company Common Stock or other securities which may be issued pursuant
to Section 7 upon exercise of the Option.  The shares of Company Common Stock to
be issued upon due exercise of the Option, including all additional shares of
Company Common Stock or other securities which may be issuable upon exercise of
the Option or any other securities which may be issued pursuant to Section 7,
upon issuance pursuant hereto, will be duly and validly issued, fully paid and
nonassessable, and will be delivered free and clear of all Liens, including
without limitation, any preemptive rights of any shareholder of the Company.

          (c) Takeover Statutes.  The Company's Board of Directors has taken all
              -----------------
appropriate and necessary actions such that Sections 302A.671, 302A.673 and
302A675 of the MBCA are inapplicable to the execution and delivery of this
Agreement and to the consummation of the transactions contemplated hereby.  No
other takeover Law as in effect on the date hereof is applicable to the
execution and delivery of this Agreement, the Company Common Stock issuable
hereunder or to the other transactions contemplated by this Agreement.  No anti-
takeover provision contained in the Company's articles of incorporation, by-laws
or agreements is applicable to the execution and

                                      -4-
<PAGE>

delivery of this Agreement, the Company Common Stock issuable hereunder or to
the other transactions contemplated by this Agreement.

               Section 6.  Representations and Warranties of Grantee.  Grantee
                           -----------------------------------------
hereby represents and warrants to the Company that any Option Shares or other
securities acquired by Grantee upon exercise of the Option will not be
transferred or otherwise disposed of except in a transaction registered, or
exempt from registration, under the Securities Act.

               Section 7.  Adjustment Upon Changes in Capitalization, etc.  (a)
                           ----------------------------------------------
In the event of any change in the Company Common Stock by reason of a stock
dividend, split-up, reverse stock split, merger, recapitalization, combination,
exchange of shares, or similar transaction, the type and number of shares or
securities subject to the Option, and the Purchase Price thereof, will be
adjusted appropriately, and proper provision will be made in the agreements
governing such transaction, so that Grantee will receive upon exercise of the
Option the number and class of shares or other securities or property that
Grantee would have received in respect of Company Common Stock if the Option had
been exercised immediately prior to such event or the record date therefor, as
applicable. Subject to Section 1, and without limiting the parties' relative
rights and obligations under the Merger Agreement, if any additional shares of
Company Common Stock are issued after the date of this Agreement (other than
pursuant to an event described in the first sentence of this Section 7(a)), the
number of shares of Company Common Stock subject to the Option will be adjusted
so that, after such issuance, it equates the Maximum Applicable Percentage.

          (b)  Without limiting the parties' relative rights and obligations
under the Merger Agreement, in the event that the Company enters into an
agreement (i) to consolidate with or merge into any person, other than Grantee
or one of its subsidiaries, and the Company will not be the continuing or
surviving corporation in such consolidation or merger, (ii) to permit any
person, other than Grantee or one of its subsidiaries, to merge into the Company
and the Company will be the continuing or surviving corporation, but in
connection with such merger, the shares of Company Common Stock outstanding
immediately prior to the consummation of such merger will be changed into or
exchanged for stock or other securities of the Company or any other person or
cash or any other property, or the shares of Company Common Stock outstanding
immediately prior to the consummation of such merger will, after such merger,
represent less than 50% of the outstanding voting securities of the merged
company, or (iii) to sell or otherwise transfer all or substantially all of its
assets to any person, other than Grantee or one of its subsidiaries, then, and
in each such case, the agreement governing such transaction will make proper
provision so that the Option will, upon the consummation of any such transaction
and upon the terms and conditions set forth herein, be converted into, or
exchanged for, an option with identical terms appropriately adjusted to acquire
the number and class of shares or other securities or property that Grantee
would have received in respect of Company Common Stock if the Option had been
exercised immediately prior to such consolidation, merger, sale, or

                                      -5-
<PAGE>

transfer, or the record date therefor, as applicable, and make any other
necessary adjustments.

          (c)   If, at any time during the period commencing on a Purchase Event
and ending on the termination of the Option in accordance with Section 2,
Grantee sends to the Company an Exercise Notice indicating Grantee's election to
exercise its right (the "Cash-Out Right") pursuant to this Section 7(c), then
                         --------------
the Company shall pay to Grantee, on the Option Closing Date, in exchange for
the cancellation of the Option with respect to such number of Option Shares as
Grantee specifies in the Exercise Notice, an amount in cash equal to such number
of Option Shares multiplied by the difference between (i) the average closing
price, for the 10 NASDAQ/National Market System ("NASDAQ/NMS") trading days
                                                  ----------
commencing on the 12th NASDAQ/NMS trading day immediately preceding the Notice
Date, per share of Company Common Stock as reported on the NASDAQ/NMS (or, if
not listed on the NASDAQ/NMS, as reported on any other national securities
exchange or national securities quotation system on which the Company Common
Stock is listed or quoted, as reported in The Wall Street Journal (Northeast
                                          -----------------------
edition), or, if not reported therein, any other authoritative source) (the
"Closing Price") and (ii) the Purchase Price.  Notwithstanding the termination
 -------------
of the Option, Grantee will be entitled to exercise its rights under this
Section 7(c) if it has exercised such rights in accordance with the terms hereof
prior to the termination of the Option.

     Section 8. Registration Rights.  The Company will, if requested by Grantee
                -------------------
at any time and from time to time within two years of the exercise of the Option
(a "Demand Registration"), as expeditiously as possible prepare and file up to
    -------------------
two registration statements under the Securities Act if such registration is
necessary in order to permit the sale or other disposition of any or all Option
Shares or securities that have been acquired by or are issuable to Grantee upon
exercise of the Option in accordance with the intended method of sale or other
disposition stated by Grantee, including a "shelf" registration statement under
Rule 415 under the Securities Act or any successor provision, and the Company
will use its best efforts to qualify such Option Shares or other securities
under any applicable state securities laws.  The Company will use best efforts
to cause each such registration statement to become effective when requested by
Grantee, to obtain all consents or waivers of other parties which are required
therefor, and to keep such registration statement effective for such period not
in excess of 180 calendar days from the day such registration statement first
becomes effective as may be reasonably necessary to effect such sale or other
disposition.  The obligations of the Company hereunder to file a registration
statement and to maintain its effectiveness may be suspended for up to 60
consecutive calendar days if the Board of Directors of the Company shall have
determined in good faith that the filing of such registration statement or the
maintenance of its effectiveness would be seriously detrimental to the Company;
provided, however, that the suspension of the Company's obligations may occur
- --------  -------
only one time in any six-month period; provided, further, that any requested
                                       --------  -------
registration suspended hereunder will not count for purposes of requests for
Demand Registrations to which Grantee is entitled hereunder.  All expenses
related to a registration statement prepared and filed under this Section 8, and
any sale covered thereby, will be at the Company's

                                      -6-
<PAGE>

expense, except for underwriting discounts or commissions. Grantee will provide
all information reasonably requested by the Company for inclusion in any
registration statement to be filed hereunder. If, during the time periods
referred to in the first sentence of this Section 8, the Company effects a
registration under the Securities Act of Company Common Stock for its own
account or for any other shareholders of the Company (other than on Form S-4 or
Form S-8, or any successor form), it will allow Grantee the right to participate
in such registration, and such participation will not affect the obligation of
the Company to effect Demand Registrations for Grantee under this Section 8;
provided, that, if the managing underwriters of such offering advise the Company
- --------  ----
in writing that in their opinion the number of shares of Company Common Stock
requested to be included in such registration exceeds the number which can be
sold in such offering or could materially impact the marketing or prices of such
offering, the Company will include the shares requested to be included therein
by Grantee pro rata with the shares intended to be included therein by the
Company and any other seller of securities under such registration statement.
In connection with any registration pursuant to this Section 8, the Company and
Grantee will provide each other and any underwriter of the offering with
customary representations, warranties, covenants, indemnification, and
contribution in connection with such registration.

     Section 9.  Limitation on Profit.  (a)  Notwithstanding any other provision
                 --------------------
of this Agreement, in no event shall Grantee's Total Profit (as defined below)
plus any Termination Fee paid to Grantee pursuant to Section 9.3 of the Merger
Agreement exceed in the aggregate $11,865,000 and, if the total amount that
otherwise would be received by Grantee would exceed such amount, Grantee, at its
sole election, shall either (i) reduce the number of shares of Company Common
Stock subject to the Option, (ii) deliver to the Company for cancellation Option
Shares previously purchased by Grantee against the refund of the purchase price
therefor, (iii) pay cash to the Company or (iv) any combination thereof, so that
Grantee's actually realized Total Profit, when aggregated with such Termination
Fee so paid to Grantee, shall not exceed $11,865,000, based on the transaction
value after taking into account the foregoing actions.

                 (b)  Notwithstanding any other provision of this Agreement, the
Option may not be exercised for a number of Option Shares as would, as of the
date of exercise, result in a Notional Total Profit (as defined below) which,
together with any Termination Fee theretofore paid to Grantee, and after giving
effect to any election made by Grantee under Section 9(a), would exceed
$11,865,000; provided, that nothing in this sentence shall restrict any exercise
             --------
of the Option permitted hereby on any subsequent date.

                 (c)  As used herein, the term "Total Profit" shall mean the
                                                ------------
aggregate amount (before taxes) of the following: (i) the amount received by
Grantee pursuant to the Grantee's exercise of the Cash-Out Right, (ii)(x) the
net cash amounts or the fair market value of any property received by Grantee
pursuant to the sale of Option Shares (or (A) any other securities into which
such Option Shares are converted or exchanged or (B) any property, cash or other
securities received pursuant to adjustments

                                      -7-
<PAGE>

under Section 7 or delivered pursuant to Section 3(b) ("Additional Property"))
                                                        -------------------
to any unaffiliated party, but in no case less than the fair market value of
such Option Shares at the time of such sale, less (y) the Grantee's purchase
price of such Option Shares, and (iii) the net cash amounts received by Grantee
on the transfer (in accordance with Section 16(a) hereof) of the Option (or any
portion thereof) to any unaffiliated party.

                 (d)  As used herein, the term "Notional Total Profit" with
                                                ---------------------
respect to any number of Option Shares as to which Grantee may propose to
exercise the Option shall be the Total Profit determined as of the date of such
proposal assuming for such purpose that the Option were exercised on such date
for such number of Option Shares and assuming that (i) such Option Shares (or
any other securities into which such Option Shares are converted or exchanged),
together with all other Option Shares held by Grantee and its affiliates as of
such date, were sold for cash at the closing market price on the NASDAQ/NMS for
the Company Common Stock as of the close of business on the preceding trading
day (less customary brokerage commissions) and (ii) the Additional Property is
disposed of for fair market value.

     Section 10. Listing.  If Company Common Stock or any other securities to
                 -------
be acquired upon exercise of the Option are then listed on the NASDAQ/NMS (or
any other national securities exchange or national securities quotation system),
the Company, upon the request of Grantee, will promptly file an application to
list the shares of Company Common Stock or other securities to be acquired upon
exercise of the Option on the NASDAQ/NMS (and any other such national securities
exchange or national securities quotation system) and will use its best efforts
to obtain approval of such listing as promptly as practicable.

     Section 11. Survival of Representations and Warranties.  All
                 ------------------------------------------
representations and warranties in this Agreement or in any instrument delivered
pursuant to this Agreement shall survive for twelve months after the termination
of the Option.  The covenants and agreements made herein will survive in
accordance with their respective terms.

     Section 12. Expenses.  Except as otherwise provided in the Merger
                 --------
Agreement, all costs and expenses incurred in connection with this Agreement
shall be paid by the party incurring such expenses.

     Section 13. Counterparts.  This Agreement may be executed in two or more
                 ------------
counterparts, all of which shall be considered the same agreement.

     Section 14. Governing Law.  This Agreement shall be governed by and
                 -------------
construed in accordance with the laws of the State of Minnesota, without regard
to principles of conflicts of laws thereof.

     Section 15. Notices.  All notices and other communications hereunder shall
                 -------

     Section 16.  Miscellaneous. (a) This Agreement shall not, nor shall any of
                  -------------
the rights or interests hereunder, be assigned by any party hereto or assignable
by operation of law or otherwise without the prior written consent of the other
parties hereto; provided, however, that Purchaser may assign its rights
hereunder to an affiliate, but nothing shall relieve the assignor from its
obligations hereunder.  Subject to the preceding sentence, this Agreement shall
be binding upon and shall inure to the benefit to the parties hereto and their
respective successors and assigns.

     (b)  The headings contained in this Agreement are for reference purposes
and shall not affect in any way the meaning or interpretation of this Agreement.
In this Agreement, unless the context otherwise requires, words describing the
singular number shall include the plural and vice versa, and words denoting any
gender shall include all genders and words denoting natural persons shall
include corporations and partnerships and vice versa. Whenever the words
"include," "includes" or "including" are used in this Agreement, they shall be
understood to be followed by the words "without limitation."

     (c)  All rights, powers and remedies provided under this Agreement or
otherwise available in respect hereof at law or in equity will be cumulative and
not alternative, and the exercise of any thereof by either party will not
preclude the simultaneous or later exercise of any other such right, power or
remedy by such party.

     Section 17.  Severability.  Any term or provision of this Agreement which
                  ------------
is invalid or unenforceable in any jurisdiction shall, as to that jurisdiction,
be ineffective to the extent of such invalidity or unenforceability without
rendering invalid or unenforceable the remaining terms and provisions of this
Agreement or affecting the validity or unenforceability of any of the terms or
provisions of this Agreement in any other jurisdiction.  If any provision of
this Agreement is so broad as to be unenforceable, the provision shall be
interpreted to be only so broad as is enforceable.

     Section 18.  Enforcement of Agreement; Waiver of Jury Trial.  (a)  The
                  ----------------------------------------------
parties hereto agree that irreparable damage would occur in the event that any
of the provisions of this Agreement were not performed in accordance with its
specific terms or was otherwise breached.  It is accordingly agreed that the
parties shall be entitled to an injunction or injunctions to prevent breaches of
this Agreement and to enforce

                                      -10-

specifically the terms and provisions hereof in any court, this being in
addition to any other remedy to which they are entitled at law or in equity.

               (b)  Each of the parties irrevocably and unconditionally waives,
to the fullest extent permitted by applicable law, any and all rights to trial
by jury in connection with any litigation arising out of or relating to this
Agreement.

                    Section 19.  Extension of Time, Waiver, Etc.  The Company
                                 ------------------------------

obligations or acts of the other party;

               (b)  waive any inaccuracies in the representations and warranties
of the other party contained herein or in any document delivered pursuant
hereto; or

               (c)  waive compliance with any of the agreements or conditions of
the other party contained herein; provided, however, that no failure or delay by
the Company or Grantee in exercising any right 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 other right hereunder.
Any agreement on the part of a party hereto to any extension or waiver
contemplated by this Section 19 shall be valid only if set forth in an instrment
in writing signed on behalf of such party.

                    Section 20.  Amendment.  This Agreement may not be amended,
                                 ----------
except by an instrument in writing signed on behalf of each of the parties.

                                 ------------------
exercise of the Option by Grantee, the Company and Grantee will execute and
deliver all other documents and instruments and take all other actions that may
be reasonably necessary in order to consummate the transactions provided for by
such exercise.
