                          AGREEMENT AND PLAN OF MERGER

     AGREEMENT AND PLAN OF MERGER, dated as of July 9, 2002 (the "Agreement"),
among Kiewit Materials Company, a Delaware corporation (the "Company"), Rinker
Materials Corporation, a Georgia corporation ("Parent"), and Jem Lear
Acquisition Company, Inc., a Delaware corporation and a wholly owned subsidiary
of Parent ("Purchaser").

                              W I T N E S S E T H:
                              - - - - - - - - - -

     WHEREAS, the Board of Directors of the Company (the "Board of Directors")
and the Board of Directors of Purchaser have each determined that it is in the
best interests of their respective stockholders for Purchaser to acquire the
Company upon the terms and subject to the conditions set forth herein; and

     WHEREAS, in furtherance thereof, it is proposed that Purchaser will make a
cash tender offer (the "Offer") to acquire all shares (the "Shares") of the
issued and outstanding common stock, $.01 par value, of the Company (the
"Company Common Stock") for $17.00 per share of Company Common Stock or such
higher price as may be paid in the Offer (the "Per Share Amount"), net to the
seller in cash; and

     WHEREAS, also in furtherance of such acquisition, the Board of Directors
and the Board of Directors of Purchaser have each approved the merger of
Purchaser with and into the Company (the "Merger") following the Offer in
accordance with the General Corporation Law of the State of Delaware ("Delaware
Law") and upon the terms and subject to the conditions set forth herein;

     NOW, THEREFORE, in consideration of the foregoing premises and the mutual
covenants and agreements herein contained, and intending to be legally bound
hereby, the Company, Parent and Purchaser hereby agree as follows:

                                    ARTICLE I

                                THE TENDER OFFER

     Section 1.1 The Offer.

     (a) Provided that this Agreement shall not have been terminated in
accordance with Section 8.1 hereof and none of the events set forth in Annex I
hereto shall have occurred and be existing, Purchaser shall commence (within the
meaning of Rule 14d-2 under the Securities Exchange Act of 1934 (the "Exchange
Act")) the Offer as promptly as reasonably practicable following the public
announcement of the execution of this Agreement, but in no event later than ten
business days following the date of the execution of this Agreement. The
obligation of Purchaser to accept for payment any Shares tendered shall be
subject only to the satisfaction of those conditions set forth in Annex I.
Parent expressly reserves the right from time to time, subject to Sections
1.1(b) and 1.1(d) hereof, to waive any such condition, to increase the Per Share
Amount, or to make any other changes in the terms and conditions of the Offer.
The Per Share Amount shall be net to the seller in cash, subject to reduction
only for any applicable back-up withholding or stock transfer taxes required by
law to be withheld from






payments to the seller. The Company agrees that no Shares held by the Company or
any of its Subsidiaries (as hereinafter defined) will be tendered pursuant to
the Offer.

     (b) Without the prior written consent of the Company, Parent shall not (i)
decrease the Per Share Amount or change the form of consideration payable in the
Offer, (ii) decrease the number of Shares sought, (iii) amend or waive
satisfaction of the Minimum Condition (as defined in Annex I) other than to
reduce the percentage of Shares in such condition to any percentage that is not
less than a majority or (iv) impose additional conditions to the Offer or amend
any other condition or term of the Offer in any manner adverse to the holders of
Shares. Upon the terms and subject to the conditions of the Offer, Purchaser
will, and Parent will cause it to, accept for payment and purchase, as promptly
as practicable after expiration of the Offer, all Shares validly tendered and
not withdrawn prior to the expiration of the Offer that Purchaser becomes
obligated to accept for payment and pay pursuant to the Offer.

     (c) The Offer shall be made by means of an offer to purchase (the "Offer to
Purchase") having only the conditions set forth in Annex I hereto. As soon as
practicable on the date the Offer is commenced, Parent and Purchaser shall file
with the Securities and Exchange Commission (the "SEC") a Tender Offer Statement
on Schedule TO (together with all amendments and supplements thereto, the
"Schedule TO") with respect to the Offer that will comply in all material
respects with the provisions of such Schedule TO and all applicable federal
securities laws, and will contain (including as an exhibit) or incorporate by
reference the Offer to Purchase and forms of the related letter of transmittal
and other ancillary Offer documents pursuant to which the Offer will be made
(which documents, together with any supplements or amendments thereto, are
referred to collectively herein as the "Offer Documents"). Parent and Purchaser
agree promptly to correct the Schedule TO or the Offer Documents if and to the
extent that any of them shall have become false or misleading in any material
respect (and the Company, with respect to written information supplied by it
specifically for use in the Schedule TO or the Offer Documents, shall promptly
notify Parent of any required corrections of such information and shall
cooperate with Parent and Purchaser with respect to correcting such information)
and to supplement the information provided by it specifically for use in the
Schedule TO or the Offer Documents to include any information that shall become
necessary in order to make the statements therein, in light of the circumstances
under which they were made, not misleading, and Parent and Purchaser further
agree to take all steps necessary to cause the Schedule TO, as so corrected or
supplemented, to be filed with the SEC and the Offer Documents, as so corrected
or supplemented, to be disseminated to holders of Shares, in each case as and to
the extent required by applicable federal securities laws. The Company and its
counsel shall be given a reasonable opportunity to review and comment on any
Offer Documents before they are filed with the SEC. In addition, Parent and
Purchaser agree to use reasonable efforts to provide the Company and its counsel
with any comments, whether written or oral, that Parent or Purchaser or either
of their counsel may receive from time to time from the SEC or its staff with
respect to the Schedule TO promptly after receipt of such comments and to
consult with the Company and its counsel prior to responding to such comments.

     (d) The Offer to Purchase shall provide for an initial expiration date of
September 25, 2002. Purchaser agrees that it shall not terminate or withdraw the
Offer or extend the expiration date of the Offer pursuant to this Agreement
unless at the expiration date of the Offer the conditions to the Offer described
in Annex I hereto shall not have been satisfied or


                                       2




earlier waived in accordance with the terms of this Agreement; provided,
however, that if, at the expiration date of the Offer (as it may be extended):

          (i) the conditions to the Offer described in Annex I hereto (other
     than the Minimum Condition) shall not have been satisfied or earlier waived
     but are reasonably capable of being satisfied on or prior to November 8,
     2002, or

          (ii) the Minimum Condition shall not have been satisfied or, to the
     extent permitted in Section 1.1(b), earlier waived;

Purchaser shall, from time to time extend the expiration date of the Offer (each
such individual extension not to exceed 10 business days (as defined in Rule
14d-1 under the Exchange Act) until the date such conditions are satisfied or
earlier waived in accordance with the terms of this Agreement, and Purchaser
becomes obligated to accept for payment and pay for Shares tendered pursuant to
the Offer; provided, further, that in the case of either clause (i) or (ii)
above, and except as otherwise set forth in Section 8.1(e) hereof, the
expiration date of the Offer shall not be extended beyond November 8, 2002,
without the prior written consent of the Company and Purchaser. Notwithstanding
the foregoing, Purchaser may, without the consent of the Company, extend the
expiration date of the Offer (as it may be extended) for any period required by
applicable rules and regulations of the SEC in connection with an increase in
the consideration to be paid pursuant to the Offer. Purchaser may provide a
"subsequent offering period" (as contemplated by, and in accordance with, Rule
14d-11 under the Exchange Act) of not less than three business days nor more
than five business days following its acceptance of and payment for the Shares
in the Offer.

     Section 1.2 Company Action.

     (a) The Company hereby approves of and consents to the Offer and represents
and warrants that the Board of Directors, at a meeting duly called and held on
July 8, 2002: (i) approved and adopted this Agreement and the transactions
contemplated hereby, including the Offer and the Merger; (ii) recommended that
the stockholders of the Company accept the Offer, tender their Shares pursuant
to the Offer and approve this Agreement and the transactions contemplated
hereby, including the Merger; (iii) determined that this Agreement and the
transactions contemplated hereby, including the Offer and the Merger, are fair
to and in the best interests of the stockholders of the Company; (iv) took all
action necessary to render the limitations on business combinations contained in
Section 203 of the Delaware Law inapplicable to this Agreement, and the
transactions contemplated hereby and thereby; and (v) waived the restrictions on
transferring Shares contained in the Company's Amended and Restated Certificate
of Incorporation (the "Restated Certificate") only to the extent necessary to
permit (x) holders of Shares to tender their Shares in the Offer and (y)
Purchaser to purchase validly tendered Shares in the Offer.

     (b) The Company hereby agrees to file with the SEC, concurrently with the
filing by Parent and Purchaser of the Schedule TO with respect to the Offer, a
Tender Offer Solicitation/Recommendation Statement on Schedule 14D-9 (together
with any amendments or supplements thereto, the "Schedule 14D-9") that will
comply in all material respects with the provisions of all applicable federal
securities laws. The Company agrees to mail such Schedule


                                       3




14D-9 to the stockholders of the Company along with the Offer Documents. The
Schedule 14D-9 and the Offer Documents shall contain the recommendation of the
Board of Directors described in Section 1.2(a) hereof. The Company agrees
promptly to correct the Schedule 14D-9 if and to the extent that it shall become
false or misleading in any material respect (and each of Parent and Purchaser,
with respect to written information supplied by it specifically for use in the
Schedule 14D-9, shall promptly notify the Company of any required corrections of
such information and cooperate with the Company with respect to correcting such
information) and to supplement the information contained in the Schedule 14D-9
to include any information that shall become necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading, and the Company shall take all steps necessary to cause the
Schedule 14D-9, as so corrected or supplemented, to be filed with the SEC and
disseminated to the Company's stockholders to the extent required by applicable
federal securities laws. Parent and its counsel shall be given a reasonable
opportunity to review and comment on the Schedule 14D-9 and any supplements
thereto before they are filed with the SEC. The Company shall provide Parent and
its counsel 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 receipt of
such comments and shall consult with Parent, Purchaser and their counsel prior
to responding to any comments.

     (c) In connection with the Offer, the Company shall promptly upon execution
of this Agreement furnish Parent with mailing labels containing the names and
addresses of all record holders of Shares, and (to the extent available)
non-objecting beneficial owners lists and security position listings of Shares
held in stock depositories, each as of the most recent practicable date, and
shall promptly furnish Parent with such additional information, including
updated lists of stockholders, mailing labels and security position listings,
and such other information and assistance as Parent or its agents may reasonably
request for the purpose of communicating the Offer to the record and beneficial
holders of Shares. Subject to the requirements of applicable law, and except for
such steps as are necessary to disseminate the Offer Documents and any other
documents reasonably necessary to consummate the Offer or the Merger, Parent and
Purchaser shall hold in confidence the information held in such labels and
listings, shall use such information solely in connection with the Offer and the
Merger, and if this Agreement is terminated or if the Offer is otherwise
terminated, shall promptly destroy or cause to be destroyed or deliver or cause
to be delivered to the Company all copies of such information then in their
possession or in the possession of their agents or representatives.

     Section 1.3 Directors. Promptly upon the purchase by Purchaser of any
Shares pursuant to the Offer, and from time to time thereafter as Shares are
acquired by Purchaser, Parent shall be entitled to designate such number of
directors, rounded up to the next whole number, on the Board of Directors as
will give Parent, subject to compliance with Section 14(f) of the Exchange Act,
representation on the Board of Directors equal to at least that number of
directors which equals the product of the total number of directors on the Board
of Directors (giving effect to the directors appointed or elected pursuant to
this sentence and including current directors serving as officers of the
Company) multiplied by the percentage that the aggregate number of Shares
beneficially owned by Parent or any affiliate of Parent (including for purposes
of this Section 1.3 such Shares as are accepted for payment pursuant to the
Offer, but excluding Shares held by the Company or any of its Subsidiaries)
bears to the number of Shares outstanding. At each such time, the Company will
also cause (i) each committee of the Board of


                                       4




Directors, (ii) if requested by Parent, the board of directors of each of the
Subsidiaries and (iii) if requested by Parent, each committee of such board to
include Persons designated by Parent constituting the same percentage of each
such committee or board as Parent's designees constitute on the Board of
Directors. The Company shall, upon request by Parent, promptly increase the size
of the Board of Directors or exercise its reasonable efforts to secure the
resignations of such number of directors as is necessary to enable Parent's
designees to be elected to the Board of Directors in accordance with the terms
of this Section 1.3 and shall cause Parent's designees to be so elected;
provided, however, that, in the event that Parent's designees are appointed or
elected to the Board of Directors, until the Effective Time (as defined in
Section 2.2 hereof) the Board of Directors shall have at least one director who
is a director on the date hereof and who is not an officer of the Company and is
not a designee, stockholder, affiliate or associate (within the meaning of the
federal securities laws) of Parent (one or more of such directors, the
"Independent Directors"); provided, further, that if no Independent Directors
remain, the other directors shall designate one Person to fill one of the
vacancies who shall be neither an officer of the Company nor a designee,
stockholder, affiliate or associate of Parent, and such Person shall be deemed
to be an Independent Director for purposes of this Agreement. Subject to
applicable law, the Company shall promptly take all action necessary pursuant to
Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder in order
to fulfill its obligations under this Section 1.3 and shall include in the
Schedule 14D-9 mailed to stockholders promptly after the commencement of the
Offer (or an amendment thereof or an information statement pursuant to Rule
14f-1 if Parent has not theretofore designated directors) such information with
respect to the Company and its officers and directors as is required under
Section 14(f) and Rule 14f-1 in order to fulfill its obligations under this
Section 1.3. Parent will supply the Company in writing and be solely responsible
for any written information with respect to itself and its nominees, officers,
directors and affiliates required by Section 14(f) and Rule 14f-1.
Notwithstanding anything in this Agreement to the contrary, following the time
directors designated by Parent constitute a majority of the Board of Directors
and prior to the Effective Time, the affirmative vote of a majority of the
Independent Directors shall be required to (i) amend, modify or terminate this
Agreement on behalf of the Company, (ii) exercise or waive any of the Company's
rights or remedies hereunder, (iii) extend the time for performance of Parent's
obligations hereunder or (iv) take any other action by the Company in connection
with this Agreement required to be taken by the Board of Directors.

                                   ARTICLE II

                                   THE MERGER

     Section 2.1 The Merger. At the Effective Time (as defined in Section 2.2)
and subject to and upon the terms and conditions of this Agreement and Delaware
Law, Purchaser shall be merged with and into the Company, the separate corporate
existence of Purchaser shall cease, and the Company shall continue as the
surviving corporation. The Company as the surviving corporation after the Merger
is hereinafter sometimes referred to as the "Surviving Corporation."

     Section 2.2 Effective Time. As promptly as practicable, and in any event
within five business days after the satisfaction or waiver of the conditions set
forth in Article VII, the parties hereto shall cause the Merger to be
consummated by filing a Certificate of Merger


                                       5




with the Secretary of State of the State of Delaware, in such form as required
by, and executed in accordance with the relevant provisions of, Delaware Law
(the time of such filing being the "Effective Time").

     Section 2.3 Effect of the Merger. At the Effective Time, the effect of the
Merger shall be as provided in the applicable provisions of Delaware Law.
Without limiting the generality of the foregoing, and subject thereto, at the
Effective Time all the property, rights, privileges, powers and franchises of
the Company and Purchaser shall vest in the Surviving Corporation, and all
debts, liabilities and duties of the Company and Purchaser shall become the
debts, liabilities and duties of the Surviving Corporation.

     Section 2.4 Subsequent Actions. If, at any time after the Effective Time,
the Surviving Corporation shall consider or be advised that any deeds, bills of
sale, assignments, assurances or any other actions or things are necessary or
desirable to vest, perfect or confirm of record or otherwise in the Surviving
Corporation its right, title or interest in, to or under any of the rights,
properties or assets of either of the Company or Purchaser acquired or to be
acquired by the Surviving Corporation as a result of, or in connection with, the
Merger or otherwise to carry out this Agreement, the officers and directors of
the Surviving Corporation shall be authorized to execute and deliver, in the
name and on behalf of either the Company or Purchaser, all such deeds, bills of
sale, assignments and assurances and to take and do, in the name and on behalf
of each of such corporations or otherwise, all such other actions and things as
may be necessary or desirable to vest, perfect or confirm any and all right,
title and interest in, to and under such rights, properties or assets in the
Surviving Corporation or otherwise to carry out this Agreement.

     Section 2.5 Certificate of Incorporation; By-Laws; Directors and Officers.

     (a) The Certificate of Incorporation of Purchaser, as in effect immediately
before the Effective Time, shall be the Certificate of Incorporation of the
Surviving Corporation until thereafter amended as provided by law and such
Certificate of Incorporation.

     (b) The By-Laws of Purchaser, as in effect immediately before the Effective
Time, shall be the By-Laws of the Surviving Corporation until thereafter amended
as provided by law, the Certificate of Incorporation of the Surviving
Corporation and such By-Laws.

     (c) The directors of Purchaser immediately before the Effective Time will
be the initial directors of the Surviving Corporation, and the officers of the
Company immediately before the Effective Time will be the initial officers of
the Surviving Corporation, in each case until their successors are elected or
appointed and qualified. If, at the Effective Time, a vacancy shall exist on the
Board of Directors or in any office of the Surviving Corporation, such vacancy
may thereafter be filled in the manner provided by law.

     Section 2.6 Conversion of Securities. At the Effective Time, by virtue of
the Merger and without any action on the part of Purchaser, the Company or the
holder of any of the following securities:

     (a) Common Stock of Purchaser. Each share of common stock, par value $.01
per share, of Purchaser (the "Purchaser Common Stock") issued and outstanding


                                       6




immediately prior to the Effective Time shall be converted into one fully paid
and nonassessable share of common stock, par value $.01 per share, of the
Surviving Corporation.

     (b) Cancellation of Treasury Stock and Parent-and Purchaser-Owned Company
Common Stock. Each share of Company Common Stock that is owned by Parent,
Purchaser or any Subsidiary of Parent or Purchaser or held in the treasury of
the Company (collectively, the "Excluded Shares") shall automatically be
canceled and retired and shall cease to exist, and no consideration shall be
delivered or deliverable in exchange therefor.

     (c) Conversion of Company Common Stock. Each share of Company Common Stock
issued and outstanding immediately prior to the Effective Time other than
Excluded Shares or Dissenting Shares (as defined in Section 2.6(d)) shall be
converted into the right to receive the Per Share Amount in cash payable to the
holder thereof upon surrender of the certificate formerly representing such
Share.

     (d) Dissenting Shares. Notwithstanding anything in this Agreement to the
contrary, shares of Company Common Stock that are issued and outstanding
immediately prior to the Effective Time and that are held by a holder who has
properly exercised and perfected appraisal rights for payment of the fair value
for such holder's shares as determined in accordance with Section 262 of
Delaware Law ("Dissenting Shares") shall not be converted into the right to
receive the Per Share Amount (but instead shall be converted into the right to
receive payment from the Surviving Corporation with respect to such Dissenting
Shares in accordance with Delaware Law), unless and until such holder shall have
failed to perfect or shall have effectively withdrawn or lost such holder's
right under Delaware Law. If any such holder of Company Common Stock shall have
failed to perfect or shall have effectively withdrawn or lost such right, each
Share of such holder shall be treated as a share of Company Common Stock that
had been converted as of the Effective Time into the right to receive the Per
Share Amount in accordance with Section 2.6(c). The Company shall give prompt
notice to Parent and Purchaser of any demands received by the Company for
appraisal of any Shares, and Parent and Purchaser shall have the right to
participate in all negotiations and proceedings with respect to such demands.
The Company shall not, except with the prior written consent of Parent and
Purchaser, make any payment with respect to, or settle or offer to settle, any
such demands.

     (e) Cancellation and Retirement of Company Common Stock. As of the
Effective Time, all Shares issued and outstanding immediately prior to the
Effective Time, shall no longer be outstanding and shall automatically be
canceled and retired and shall cease to exist, and each holder of a certificate
representing any such Shares shall, to the extent such certificate represents
such Shares, cease to have any rights with respect thereto, except, in all cases
other than Excluded Shares and Dissenting Shares, the right to receive the Per
Share Amount therefor upon surrender of such certificate in accordance with
Section 2.7.

     Section 2.7 Exchange of Certificates.

     (a) Exchange Agent. Prior to the Effective Time, Parent shall appoint a
bank or trust company reasonably acceptable to the Company to act as exchange
agent (the "Exchange Agent") to receive the funds necessary to make the payments
contemplated by Section 2.6. At the Effective Time, Parent shall deposit with
the Exchange Agent, for the benefit of the holders


                                       7




of Shares, for exchange in accordance with this Article II, cash in an amount
sufficient to make payments as provided in Section 2.6 (such cash consideration
being hereinafter referred to as the "Exchange Fund"). The Exchange Agent shall,
pursuant to irrevocable instructions of the Surviving Corporation, make payments
out of the Exchange Fund. The Exchange Fund shall not be used for any other
purpose.

     (b) Exchange Procedures. As soon as reasonably practicable after the
Effective Time, Parent shall cause the Exchange Agent to mail to each holder of
record of a certificate or certificates, which immediately prior to the
Effective Time represented outstanding Shares (the "Certificates"), whose Shares
were converted pursuant to Section 2.6(c) into the right to receive the Per
Share Amount (i) a letter of transmittal (which shall specify that delivery
shall be effected, and risk of loss and title to the Certificates shall pass,
only upon delivery of the Certificates to the Exchange Agent and shall be in
such form and have such other provisions as Parent may reasonably specify) and
(ii) instructions for effecting the surrender of the Certificates in exchange
for payment of the Per Share Amount. Upon surrender of a Certificate for
cancellation to the Exchange Agent or to such other agent or agents as may be
appointed by Parent, together with such letter of transmittal, duly executed,
Parent shall cause the Exchange Agent to pay to the holder of such Certificate
in exchange therefor the Per Share Amount for each share formerly represented by
such Certificate and the Certificate so surrendered shall forthwith be
cancelled. If payment is to be made to a Person other than the Person in whose
name the surrendered Certificate is registered, it shall be a condition of
payment that the Certificate so surrendered shall be properly endorsed or shall
be otherwise in proper form for transfer and that the Person requesting such
payment shall have paid any transfer and any other taxes required by reason of
the payment to a Person other than the registered holder of the Certificate
surrendered or shall have established to the satisfaction of the Surviving
Corporation that such tax either has been paid or is not applicable. Until
surrendered as contemplated by this Section 2.7(b), each Certificate shall be
deemed at any time after the Effective Time to represent only the right to
receive the Per Share Amount in cash as contemplated by Section 2.6(c). The
right of any stockholder to receive the Per Share Amount shall be subject to and
reduced by any applicable withholding obligation. After the Effective Time,
there shall be no further transfer on the records of the Company or its transfer
agent of Certificates which have been converted pursuant to this Agreement into
the right to receive the Per Share Amount, and if such Certificates are
presented to the Company for transfer, they shall be canceled against delivery
of the Per Share Amount. No interest will be paid or will accrue on any cash
payable upon the surrender of a Certificate which immediately before the
Effective Time represented outstanding Shares.

     (c) No Further Ownership Rights in Company Common Stock Exchanged For Cash.
All cash paid upon the surrender for exchange of Certificates representing
Shares in accordance with the terms of this Article II shall be deemed to have
been paid in full satisfaction of all rights pertaining to the Shares exchanged
for cash theretofore represented by such Certificates.

     (d) Termination of Exchange Fund. Any portion of the Exchange Fund which
remains undistributed to the holders of the Certificates for six months after
the Effective Time shall be delivered to the Surviving Corporation and any
holders of Shares prior to the Merger


                                       8




who have not theretofore complied with this Article II shall thereafter look
only to the Surviving Corporation and only as general creditors thereof for
payment of the Per Share Amount.

     (e) No Liability. None of Purchaser, Parent, the Surviving Corporation or
the Exchange Agent, or any employee, officer, director, agent or affiliate
thereof, shall be liable to any Person in respect of any cash from the Exchange
Fund delivered to a public official pursuant to any applicable abandoned
property, escheat or similar law. If any Certificates representing Shares shall
not have been surrendered prior to five years after the Effective Time (or
immediately prior to such earlier date on which any consideration to be paid
hereunder in respect of such Certificate would otherwise escheat to or become
the property of any Governmental Entity), any cash, shares, dividends or
distributions payable in respect of such Certificate shall, to the extent
permitted by applicable law, become the property of the Surviving Corporation
free and clear of all claims or interests of any Person previously entitled
thereto.

     (f) Investment of Exchange Fund. The Exchange Agent shall invest any cash
included in the Exchange Fund, as directed by the Surviving Corporation. Any
interest and other income resulting from such investments shall be paid to the
Surviving Corporation. To the extent that there are losses with respect to such
investments, or the Exchange Fund diminishes for other reasons below the level
required to make prompt payments of the Per Share Amount as contemplated hereby,
the Surviving Corporation shall promptly replace or restore the portion of the
Exchange Fund lost through investments or other events so as to ensure that the
Exchange Fund is, at all times, maintained at a level sufficient to make such
payments.

     (g) Withholding Rights. The Surviving Corporation shall be entitled to
deduct and withhold from the consideration otherwise payable pursuant to this
Agreement to any holder of Shares such amounts as the Surviving Corporation is
required to deduct and withhold with respect to the making of such payment under
the Internal Revenue Code of 1986, as amended (the "Code"), or any provision of
state, local or foreign tax law. To the extent that amounts are so deducted and
withheld by the Surviving Corporation, such withheld amounts shall be treated
for all purposes of this Agreement as having been paid to the holder of the
Shares in respect of which such deduction and withholding was made by the
Surviving Corporation.

     (h) 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 require as indemnity against any claim
that may be made against it with respect to such Certificate, the Exchange Agent

any Employee Plan, engaged in or been a party to any "prohibited transaction",
as such term is defined in Section 4975 of the Code or Section 406 of ERISA,
which could result in the imposition of a material penalty assessed pursuant to
Section 502(i) of ERISA, a material tax imposed by Section 4975 of the Code or
other material liability, in each case applicable to the Company, any Subsidiary
or any Employee Plan. The


                                       18




Company, its Subsidiaries and all Employee Plans are and have at all times been
in compliance in all material respects with their obligations under the Employee
Plans and the applicable requirements prescribed by all statutes, orders, or
governmental rules or regulations in effect with respect to such Employee Plans,
including, but not limited to, ERISA and the Code and, to the knowledge of the
Company and its Subsidiaries, there are no pending or threatened claims,
lawsuits or arbitrations (other than routine claims for benefits), relating to
any of the Employee Plans, which have been asserted or instituted against the
Company and its Subsidiaries, any Employee Plan or the assets of any trust or
arrangement created under or as part of any Employee Plan. Each Employee Plan
intended to qualify under Section 401(a) of the Code, and the trusts created
thereunder intended to be exempt from tax under the provisions of Section 501(a)
of the Code, either (i) has received a favorable determination letter from the
Internal Revenue Service to such effect or (ii) is still within the "remedial
amendment period," as described in Section 401(b) of the Code and the
regulations thereunder. All contributions or payments required to be made or
accrued before the Effective Time under the terms of any Employee Plan will have
been made or accrued by the Effective Time. All contributions to the Employee
Plans have been made in accordance with actuarial recommendations, as
applicable, and are currently deductible under the Code, and no excise or
penalty taxes are assessable as a result of nondeductible or other contributions
made or not made to any Employee Plan. No Employee Plan subject to Section 412
of the Code has incurred any "accumulated funding deficiency" (as defined in
ERISA), whether or not waived. Schedule 4.12 sets forth the extent, if any, to
which any of such Employee Plans has: (A) incurred employer liability with
respect to any of such plans as determined in accordance with Sections 4062 or
4063 of ERISA; (B) become entitled to a Lien under Section 412(n) of the Code;
or (C) been the subject of a minimum funding waiver. Neither the Company nor any
Subsidiary has incurred nor reasonably expects to incur any liability to the
Pension Benefit Guaranty Corporation with respect to any Employee Plan other
than liability to pay premiums. Neither the Company nor any Subsidiary has
incurred any withdrawal liability to any "multiemployer plan" (as defined in
Section 3(37) of ERISA). To the extent the Company currently has such
information, Schedule 4.12 sets forth the withdrawal liability that exists under
each multiemployer plan as of the most recent date for which such information is
available (and the Company will use its reasonable best efforts to obtain and
provide to Parent the most recent withdrawal liability available in all other
cases as soon as practicable after the date of this Agreement). Except as set
forth in Schedule 4.12, neither the execution, delivery or performance of this
Agreement will accelerate the time of payment or vesting, or increase the
amount, of compensation or benefits due under any Employee Plan. Except as set
forth in Schedule 4.12, each Employee Plan is terminable in accordance with the
terms expressly set forth therein, except as may be limited by applicable law.
No Employee Plan provides death, medical or other welfare benefits with respect
to current or former employees, officers, directors, agents or independent
contractors or their beneficiaries after retirement or other termination of
service, other than coverage mandated by applicable law.

     Section 4.13 Offer Documents; Proxy Statement. The Schedule 14D-9 will
comply as to form in all material respects with the Exchange Act and the rules
and regulations thereunder. Neither the Schedule 14D-9 (including any
information included therein pursuant to Rule 14f-1) nor any of the information
relating to the Company or its affiliates provided by or on behalf of the
Company specifically for inclusion in the Schedule TO or the Offer Documents
will, at the respective times the Schedule 14D-9, the Schedule TO and the Offer

given to stockholders 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 made therein, in light of the
circumstances under which they were made, not misleading. The Proxy Statement
will comply as to form in all material respects with the applicable requirements
of the Exchange Act and the rules and regulations thereunder. The Proxy
Statement will not, at the time the Proxy Statement (or any amendment or
supplement thereto) is first sent to stockholders or at the time of the Company
Stockholders' Meeting, 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. Notwithstanding the foregoing, the Company does not
make any representation or warranty with respect to written information supplied
by Parent, Purchaser or their officers, directors, representatives, agents,
employees or designees to the Board of Directors specifically for inclusion in
the Schedule 14D-9 (including any information that is supplied by Parent,
Purchaser or their officers, directors, representatives, agents, employees or
Parent's or Purchaser's designees to the Board of Directors, for inclusion
therein pursuant to Rule 14f-1) or the Proxy Statement.

Company or any of the Subsidiaries (collectively, the "Company Representatives")
not to, (i) solicit or initiate any inquiries regarding or the submission of,
any Takeover Proposal (as defined below), (ii) participate in any discussions or
negotiations regarding, or furnish to any Person any information with respect
to,


                                       29




any Takeover Proposal or (iii) enter into any agreement with respect to any
Takeover Proposal or approve any Takeover Proposal; provided, however, that
nothing contained in this Section 5.2 or any other provision of this Agreement
shall prohibit the Company or the Board of Directors, from (A) taking and
disclosing to the Company's stockholders a position with respect to a tender or
exchange offer by a Third Party pursuant to Rules 14d-9 and 14e-2 promulgated
under the Exchange Act or (B) making any disclosure to the Company's
stockholders, if, based on advice from outside counsel, the Board of Directors
determines in good faith, that failing to do so would be reasonably likely to
violate its fiduciary duty under Delaware Law. Upon execution of this Agreement,
the Company shall, and it shall cause the Company Representatives to,
immediately cease any existing activities, discussions or negotiations with any
parties conducted heretofore with respect to any of the foregoing.
Notwithstanding the foregoing, prior to the time of acceptance of Shares for
payment pursuant to the Offer, the Company may furnish information concerning
its business, properties or assets to any Person or group, and may negotiate and
participate in discussions and negotiations with such Person or group concerning
a Takeover Proposal if: (x) such Person or group has submitted an unsolicited
written Takeover Proposal which the Board of Directors believes in good faith is
reasonably likely to lead to a Superior Proposal; and (y) the Board of Directors
determines in good faith, based upon advice of outside counsel that failing to
do so would be reasonably likely to violate the Board of Director's fiduciary
duties to the Company's stockholders under Delaware law. The Company will
promptly notify Parent of the existence and material terms of any proposal or
inquiry received by the Company from a Third Party after the date hereof with
respect to any Takeover Proposal prior to furnishing any non-public information
to, entering into negotiations with, or accepting a Superior Proposal from, such
Third Party. The Company shall use all reasonable efforts to keep Parent
informed of the status and details of any such Superior Proposal.

     As used in this Agreement, the following terms have the meanings set forth
below:

     "Superior Proposal" means an unsolicited bona fide written Takeover
Proposal by a Third Party, and (i) on terms which the Board of Directors
determines in good faith to be more favorable to the Company's stockholders than
the Offer and the Merger (based on advice of the Company's independent financial
advisor), (ii) for which financing, to the extent required, is then committed or
which in the good faith judgment of the Board of Directors is reasonably likely
to be obtained by such Third Party and (iii) which, in the good faith reasonable
judgment of the Board of Directors of the Company, is reasonably likely to be
consummated.

     "Takeover Proposal" means any proposal or offer from a Third Party to
acquire beneficial ownership (as defined under Rule 13d-3 under the Exchange
Act) of all or a material portion of the assets of the Company or any of its
material Subsidiaries or 30% or more of any class of equity securities of the
Company or any of such Subsidiaries pursuant to a merger, consolidation or other
business combination, sale of shares of capital stock, sale of assets, tender
offer, exchange offer or similar transaction with respect to either the Company
or any of such Subsidiaries. A "material portion" of the assets of the Company
or a material Subsidiary shall be at least 30% of the book value of such
entity's assets.

     "Third Party" means any Person or group other than Parent, Purchaser or any
affiliate thereof.


                                       30




     (b) Except as set forth in this Section 5.2(b), neither the Board of
Directors nor any committee thereof shall (i) withdraw or modify, or propose to
withdraw or modify, in a manner adverse to Parent or Purchaser, the approval or
recommendation by the Board of Directors or any such committee of this Agreement
or the transactions contemplated hereby, including the Offer or the Merger, (ii)
approve or recommend, or propose to approve or recommend, any Takeover Proposal
or (iii) enter into any agreement with respect to any Takeover Proposal.
Notwithstanding anything in this Agreement to the contrary, prior to the time of
acceptance for payment of Shares pursuant to the Offer, the Board of Directors
may withdraw or modify its approval or recommendation of this Agreement or the
transactions contemplated hereby, including the Offer or the Merger, approve or
recommend a Superior Proposal, or enter into an agreement with respect to a
Superior Proposal, in each case if (A) the Company shall have received a
Superior Proposal and (B) the Board of Directors shall have determined in good
faith, based upon advice of outside counsel that failing to take such action
would be reasonably likely to violate the Board of Director's fiduciary duties
to the Company's stockholders under Delaware law.

                              ADDITIONAL AGREEMENTS

     Section 6.1 Proxy Statement. If stockholder approval of the Agreement is
required under Delaware Law and the Restated Certificate, and if a Proxy
Statement is required under the Exchange Act, the Company shall, as promptly as
practicable after the consummation of the Offer, prepare and file with the SEC,
and shall use all reasonable efforts to have cleared by the SEC, and promptly
thereafter shall mail to the Company's stockholders, the Proxy Statement. Parent
and Purchaser will cooperate with the Company in connection with the preparation
of the Proxy Statement including, but not limited to, furnishing to the Company
any and all information regarding Parent and its affiliates as may be required
to be disclosed therein. The Company shall notify Parent promptly of the receipt
of any oral or written 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 shall supply Parent with copies of all written
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. The Company shall provide Parent with a reasonable opportunity to
review and comment on the Proxy Statement and any amendment or supplement
thereto or any other materials comprising a communication to or solicitation of
stockholders prior to the filing thereof with the SEC and will provide Parent
with a copy of all such filings with the SEC. If at any time prior to the
Company Stockholders' Meeting, any event with respect to Parent or Purchaser, or
with respect to information supplied by Parent or Purchaser specifically for
inclusion in the Proxy Statement shall occur which is required to be described
in an amendment of, or supplement to, the Proxy Statement, such event shall be
so described by Parent and Purchaser and provided to the Company. The Company
shall promptly file an amendment or supplement to the Proxy Statement with
respect to such information or any information about the Company or its
Subsidiaries which requires the filing of an amendment or supplement. Subject to
the terms of this Agreement, the Proxy Statement shall contain the
recommendation of the Board of Directors that the Company's stockholders approve
this Agreement and the Merger.


                                       31




     Section 6.2 Meeting of Stockholders of the Company. If stockholder approval
of the Agreement is required under Delaware Law and the Restated Certificate,
the Company shall following the consummation of the Offer, promptly take all
action necessary in accordance with Delaware Law, the Restated Certificate and
the Company's By-Laws to convene the Company Stockholders' Meeting. Parent shall
vote, or cause to be voted, in favor of this Agreement and the Merger all Shares
directly or indirectly beneficially owned by it. The stockholder vote or consent
required for approval of the Merger will be no greater than that set forth in
Delaware Law. Subject to the fiduciary duty of the Board of Directors, the
Company shall use all reasonable efforts to solicit from stockholders of the
Company proxies in favor of the Merger and shall take all other action necessary
or, in the reasonable opinion of Parent, advisable to secure any vote or consent
of stockholders required by Delaware Law to effect the Merger. Notwithstanding
the foregoing, if Purchaser or any other subsidiary of Parent shall acquire at
least ninety percent (90%) of the outstanding Shares on a fully diluted basis,
and provided that the conditions set forth in Article VII shall have been
satisfied or waived, the Company shall, at the request of Parent, take all
necessary and appropriate action to cause the Merger to become effective as soon
as practicable after such acquisition, without the approval of the stockholders
of the Company, in accordance with Section 253 of the Delaware Law.

     Section 6.3 Additional Agreements. The Company, Parent and Purchaser will
each comply in all material respects with all applicable laws and with all
applicable rules and regulations of any Governmental Entity in connection with

contemplated hereby.

may be, or any officer, director, employee or agent thereof, to comply with or

or make any such public statement before such consultation, except as may be
required by law, judicial process or applicable stock exchange rules.

     Section 6.7 Reasonable Efforts; Cooperation; Deliveries.

     (a) Reasonable Efforts; Cooperation. Upon the terms and subject to the
conditions hereof, each of the parties hereto shall use all reasonable efforts

obligation to pay any fee or offer or grant other financial or other
accommodation to any third party for the purpose of obtaining any estoppel
certificate or any costs and expenses of any third party resulting from the
process of obtaining such estoppel certificate. In the event the Company is
unable to obtain estoppel certificates from any of the lessors of the Properties
set forth on Schedule 6.7(b) on or prior to the Tender Offer Effective Time,
then the Company will provide Purchaser with a written explanation as to why, to
the knowledge of Company personnel involved in the process of obtaining such
estoppel certificates, such estoppel certificates were not provided.

     Section 6.8 Agreement to Defend and Indemnify.

     (a) Parent hereby agrees, and shall cause the Surviving Corporation to
agree from and after the Effective Time, that all rights to indemnification
existing in favor of the present or former directors, officers, employees or
agents of the Company and its Subsidiaries and persons serving in like
capacities for another corporation or entity at the request of the Company
(collectively, the "Indemnified Parties") for costs or expenses (including
reasonable attorneys' fees), judgments, fines, losses, claims, damages,
liabilities and amounts paid in settlement in connection with any claim, action,
suit, proceeding or investigation arising out of or pertaining to any act or
omission of any such Person occurring at or prior to the Effective Time,
including, without limitation, the transactions contemplated hereby, as provided
in the Restated Certificate or By-Laws and the certificate or articles of
incorporation, by-laws or similar organizational documents of any of the
Subsidiaries, in each case as in effect as of the date of this Agreement, shall
survive the Merger and shall continue in full force and effect for six years
after the Effective Time (without modification or amendment, except as required
by applicable law) in accordance with their terms, to the fullest extent
permitted by law, and shall be enforceable by the Indemnified Parties against
the Surviving Corporation. In the event of any such claim, action, suit,
proceeding or investigation (whether arising before or after the Effective
Time), (i) the Surviving Corporation shall pay the reasonable fees and expenses
of counsel selected by the Indemnified Parties, which counsel shall be
reasonably satisfactory to the Surviving Corporation and to the insurer under
the Run-Off Coverage (as defined below), and (ii) the Surviving Corporation will
cooperate in the defense of any such matter; provided, however, that the
Surviving Corporation shall not be liable for any settlement effected without
its written consent (which consent shall not be unreasonably withheld); and
further, provided, that the Surviving Corporation shall not be obligated
pursuant to this Section 6.8 to pay the fees and disbursements of more than one
counsel for all Indemnified Parties in any single action except to the extent
that, in the written opinion of counsel for the Indemnified Parties provided to
the Surviving Corporation, two or more of such Indemnified Parties have
conflicting interests in the outcome of such action which cannot be or has not
been, in the opinion of such counsel, waived. Notwithstanding the foregoing, the
Surviving Corporation shall not have any obligation to make any payment under
this Section 6.8(a) unless (i) the carrier of the Run-Off Coverage has denied
coverage of the claim or any portion of the claim for which indemnification is
being sought and the claimant has cooperated with the reasonable requests of the
Surviving Corporation regarding the Run-Off Coverage or (ii) the Run-Off
Coverage has been exhausted.

     (b) The Company has, obtained (or will obtain prior to the Effective Time)
"run-off" coverage (the "Run-Off Coverage") for its existing directors' and
officers' liability insurance policy, and such other insurance policies listed
on such Schedule 6.8, in an amount not less than the respective coverage in
place as of the date hereof as set forth on such schedule. Parent shall not, and
shall cause the Surviving Corporation not to, terminate or modify the Run-Off
Coverage. Neither Parent nor the Surviving Company shall have any obligation to
purchase any additional insurance with respect to the Indemnified Parties or
make any payments with respect to the Run-Off Coverage.

     (c) This Section 6.8 shall survive the consummation of the Merger.
Notwithstanding Section 9.7 hereof, this Section 6.8 is intended to be for the
benefit of and to


                                       35




grant third-party rights to Indemnified Parties whether or not parties to this
Agreement, and each of the Indemnified Parties shall be entitled to enforce the
covenants contained herein.

     (d) If the Surviving Corporation or any of its successors or assigns (i)
consolidates with or merges into any other Person and shall not be the
continuing or surviving corporation or entity of such consolidation or merger or
(ii) transfers all or substantially all of its properties and assets to any
Person, then and in each such case, proper provision shall be made so that the
successors and assigns of the Surviving Corporation assume the obligations set
forth in this Section 6.8.

     Section 6.9 Continuation of Employee Benefits.

     (a) From and after the Effective Time, Parent will cause the Surviving
Corporation and its Subsidiaries to comply with the terms of all written
existing employment, severance, consulting and salary continuation agreements
between the Company or any Subsidiary and any current or former officer,
director, employee or consultant of the Company or any Subsidiary or group of
such officers, directors, employees or consultants, in each case only to the
extent disclosed in Schedule 6.9; provided, however, that nothing in the
foregoing restricts in any way whatsoever the right to terminate any Person
subject only by the terms of disclosed employment contracts and any applicable
law.

     (b) To the extent permitted under any applicable law, each employee of the
Company or any Subsidiary shall be given credit under the following employee
benefit plans maintained by Parent in which they become participants as
employees of the Surviving Corporation or any Subsidiary for all service
currently credited by the Company or such Subsidiary under comparable plans of
the Company or any Subsidiary, only as follows:

          (i) Under Parent's 401(k) plans, for purposes of eligibility to
     participate and vesting;

          (ii) Under Parent's severance policy, for purposes of eligibility to
     participate and the calculation of the amount of the severance payment; and
     under the Company's severance policy, such calculation is currently made on
     the basis of one week of severance pay for each full year of service (but
     limited in all events to 26 weeks of severance pay); and

          (iii) Under Parent's paid time off policy, for purposes of eligibility
     to participate and of the calculation of the amount to be accrued.

If any such employee participates in any of Parent's defined benefit pension
plans (which is not expected to occur), no service credit will be granted.

     (c) This Section 6.9, which shall survive the consummation of the Merger at
the Effective Time and shall continue without limit, is intended to benefit and
bind the Company, its Subsidiaries, the Surviving Corporation and any Person
referenced in this Section 6.9, each of whom may enforce the provisions of this
Section 6.9 whether or not parties to this Agreement. Except as provided in
clause (a) above, nothing contained in this Section 6.9 shall create any

     of the outstanding Shares; or

          (ii) if the Offer expires without Parent or Purchaser purchasing any
     Shares thereunder, provided that Parent or Purchaser may not terminate this
     Agreement pursuant to this Section 8.1(d)(ii) if Parent or Purchaser is in
     material breach of this Agreement; or

          (iii) (A) if the Company shall have breached in any material respect

     shall have breached any of its representations or warranties contained in
     this Agreement, which breach (x) (without regard to any materiality
     qualifier in such representation or warranty) has or is reasonably likely
     to have a Material Adverse Effect and (y) has not been cured within thirty
     days following written notice thereof to the Company from Parent; or

     (e) Notwithstanding any provision in this Agreement to the contrary, if
there shall have occurred any event, or the disclosure of any act, omission,
fact or circumstance, that individually or when considered together with any
other matter, may have a Material Adverse Effect, and the Company has a claim
for an insurance recovery for any such occurrence, which, if paid (or if the
carrier accepts coverage for such claim), would result in there being no
Material Adverse Effect,

          (i) Parent or Purchaser shall not have the right to terminate this
     Agreement pursuant to Section 8.1(d)(ii)-(iv) based in whole or in part
     upon any such occurrence; and such occurrence shall not be deemed for the
     purposes of this Agreement (including without limitation Annex I hereto) to
     constitute a Material Adverse Effect, until the carrier of any applicable
     insurance has provided a final written notice to the Company of whether
     coverage of any such claim or any portion of such claim for which a
     recovery is being sought will be unconditionally accepted or denied (a
     "Insurance Recovery Notice"); and

          (ii) all references in this Agreement to November 8, 2002 shall be
     deemed to be extended to ten (10) business days after the date on which
     such Insurance Recovery Notice is obtained, but in no event shall such date
     be extended beyond December 8, 2002; and

          (iii) pending the receipt of any Insurance Recovery Notice, the
     parties shall comply with the terms of this Agreement, including without
     limitation Article 1.

Agreement by either the Company or Parent or Purchaser as provided in Section
8.1, this


                                       39




Agreement shall forthwith become void and have no effect, without any liability
or obligation on the part of Parent, Purchaser or the Company, other than the
provisions of this Article VIII and as provided in Section 9.1 and except that
nothing herein (other than as provided in Section 8.2(b)) shall relieve any
party for willful breach of any of its representations, warranties, covenants or
agreements set forth in this Agreement.

     (b) If (x) Parent or Purchaser terminates this Agreement pursuant to
Section 8.1(d)(i) or (y) the Company terminates this Agreement pursuant to
Section 8.1(c)(i), then in either such case, the Company shall pay, or cause to
be paid to Parent not later than the second business day following the date of
such termination, an amount equal to $22,700,000 (the "Termination Fee") plus an
amount equal to Parent's and Purchaser's actual and reasonably documented
out-of-pocket expenses (but in no event exceeding in the aggregate $2,000,000)
incurred by Parent or Purchaser directly in connection with the Offer, the
Merger, this Agreement and the consummation of the transactions contemplated
hereby, including, without limitation, the fees and expenses of Parent's counsel

investment banking firms and their respective counsel incurred in connection

transactions contemplated hereby (the "Reimbursable Expenses"). Notwithstanding
anything in this Agreement to the contrary, the prompt payment of the
Termination Fee and the Reimbursable Expenses shall be the exclusive remedy of
Parent and Purchaser with respect to a termination of this Agreement pursuant to
Section 8.1(c)(i) or Section 8.1(d)(i).

tendered Shares promptly after termination or withdrawal of the Offer), pay for,
and (subject to any such rules or regulations) may delay the acceptance for
payment of any tendered Shares and (except as provided in this Agreement) amend
or terminate the Offer as to any Shares not then paid for if (i) there shall not
have been validly tendered and not withdrawn prior to the expiration of the
Offer a number of shares of Company Common Stock which, when taken together with

          (a) there shall be an injunction or other order, decree, judgment or
     ruling issued, initiated or threatened and not withdrawn by a Governmental
     Entity of competent jurisdiction or a statute, rule, regulation, executive
     order or other action shall have been enacted, promulgated or taken or
     initiated or threatened and not withdrawn by a Governmental Entity of
     competent jurisdiction which in any such case (i) restrains or prohibits or
     seeks to restrain or prohibit the making or consummation of the Offer or
     the consummation of the Merger, (ii) prohibits or restricts or seeks to
     prohibit or restrict the ownership or operation by Parent (or any of its
     affiliates or subsidiaries) of any material portion of its or the Company's
     business or assets, or compels Parent (or any of its affiliates or
     subsidiaries) to dispose of or hold separate any portion of its or the
     Company's or any of its Subsidiary's business or assets which is material

     or (iv) imposes or seeks to impose any material limitations on the ability
     of Parent or any of its respective affiliates or subsidiaries effectively
     to control in any material respect the business and operations of the
     Company and its Subsidiaries; provided, however, that in the case of any

     shall be reasonably likely to have one of the foregoing effects; or

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

          (c) from and after the date of this Agreement, there shall have

     circumstance not disclosed pursuant to this Agreement or any SEC Report,
     that, individually or when considered together with any other matter, has a
     Material Adverse Effect (with any liability or obligation associated with
     any such previously undisclosed act, omission, fact or circumstance being






     deemed, for purposes of determining whether a Material Adverse Effect has
     occurred, to have been incurred or increased, as the case may be, upon such
     disclosure); or

          (d) there shall have occurred and be continuing (i) any general
     suspension of trading in, or limitation on prices for, securities on the
     New York Stock Exchange or the Nasdaq National Market (excluding any
     coordinated trading halt triggered as a result of a specified decrease in a
     market index) related to market conditions, (ii) a declaration of a banking

     in Section 4.2 of this Agreement shall not be accurate in all respects, in
     each case as if such representations and warranties were remade at and as
     of the time of such determination; or

          (f) any of the representations and warranties of the Company set forth
     in this Agreement (other than those in Section 4.2) (without regard to any
     materiality qualifications therein) shall not be accurate, except where
     such inaccuracies (considered collectively) do not have a Material Adverse
     Effect (determined in the manner provided in clause (c) above), in each
     case as if such representations and warranties were remade at and as of the
     time of such determination; or

          (g) the Company shall have failed to perform in any respect any
     obligation, agreement or covenant of the Company to be performed or
     complied with by it under Section 5.1(a) through (l), of this Agreement; or

          (h) the Company shall have failed to perform in any material respect
     any material obligation (including, without limitation, the Company's
     obligation pursuant to the first sentence of Section 5.1, but excluding
     those set forth in Section 5.1(a) through (l)) or to comply in any material
     respect with any material agreement or covenant of the Company to be
     performed or complied with by it under this Agreement; or

          (i) the Board of Directors (i) shall have withdrawn, or modified or
     changed in a manner adverse to Parent or Purchaser its approval or
     recommendation of this Agreement or the transactions contemplated hereby,
     including the Offer and the Merger, (ii) recommended a Takeover Proposal,
     (iii) shall have adopted any resolution to effect any of the foregoing,
     (iv) waived the transfer restrictions in the Restated Certificate to enable
     a Third Party to acquire more than 15% of the outstanding Shares; or

          (j) all authorizations, consents and approvals, if any, of any
     Governmental Entity necessary for the execution, delivery and performance
     of this Agreement, the failure to obtain which would prevent or materially
     impair or delay consummation of the


                                      I-2




     transactions contemplated hereby or have a Material Adverse Effect, shall
     not have been obtained or be in full force and effect; or

          (k) Parent shall not have received any of the documents to be
     delivered to Parent pursuant to Section 6.7(e) of the Agreement, or

          (l) the transactions and all deliveries contemplated by the Columbia
     River Property Agreement shall not have been consummated or delivered, as
     the case may be;

which, in the reasonable judgment of Parent with respect to each and every
matter referred to above and regardless of the circumstances giving rise to any
such condition, makes it inadvisable to proceed with the Offer or with such
acceptance for payment of or payment for Shares.

     The foregoing conditions are for the sole benefit of Parent and may be
asserted by Purchaser regardless of the circumstances giving rise to any such
conditions and may be waived by Purchaser in whole or in part at any time and
from time to time, in each case, in the exercise of the good faith judgment of
Purchaser and subject to the terms of this Agreement. The failure by Purchaser
at any time to exercise any of the foregoing rights shall not be deemed a waiver
of any such right and each such right shall be deemed an ongoing right which may
be asserted at any time and from time to time.
