CUSIP NO. 961748 20 9

ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

          Pursuant to the Stockholders Agreement dated as of August 8, 2002 (the
"Stockholders Agreement"), among Parent, Sub, the Issuer, Ernest H. McKee
("McKee") and William J. Preston (McKee, William J. Preston and each stockholder
of the Issuer that may from time to time become a party to the Stockholders
Agreement are referred to herein, collectively, as the "Stockholders"),
Holdings, Parent and Sub may be deemed to be the beneficial owners of 3,245,648
shares of Issuer Common Stock (of which 1,098,050 shares of Issuer Common Stock
are issuable pursuant to the exercise, exchange or conversion of options,
warrants and convertible notes of the Issuer which are currently exercisable,
exchangeable or convertible, as applicable, or will become exercisable,
exchangeable or convertible, as applicable, at any time within 60 days from the
date of this Statement) (collectively, the "Initial Subject Shares"). In
addition, 90,000 shares of Issuer Common Stock (all of which are issuable
pursuant to the exercise of options of the Issuer that are not currently
exercisable and that will not become exercisable at any time within 60 days from
the date of this Statement) (collectively, the "Additional Subject Shares" and,
together with the Initial Subject Shares, the "Subject Shares") are subject to
the terms and conditions of the Stockholders Agreement. Parent, Sub, the Issuer
and the Stockholders entered into the Stockholders Agreement to induce Parent
and Sub to enter into the Agreement and Plan of Merger dated as of August 8,
2002 (the "Merger Agreement"), among Parent, Sub and the Issuer. Pursuant to the
Merger Agreement, on the terms and subject to the conditions set forth therein,
Sub would merge with and into the Issuer (the "Merger"), with the Issuer
continuing as the surviving corporation in the Merger (the "Surviving
Corporation"), and becoming a wholly owned subsidiary of Parent. In connection
with the Merger, each outstanding share of Issuer Common Stock would be
converted into the right to receive $2.30 in cash, without interest (as such
$2.30 amount may be appropriately adjusted to take into account any stock
dividend, split, reverse split, combination, reclassification, merger,
recapitalization, share exchange or other similar transaction occurring prior to
the consummation of the Merger, the "Deal Price") and each outstanding share of
common stock, par value $0.003 per share, of Sub would be converted into one
share of common stock, par value $0.003 per share, of the Surviving Corporation.
The consummation of the Merger is subject to certain conditions. The
descriptions of the Merger Agreement and the Stockholders Agreement contained
herein are qualified in their entirety by reference to such agreements, which
are attached hereto as Exhibits 1 and 2, respectively.

ITEM 4. PURPOSE OF TRANSACTION.

          (a)-(b) The Stockholders Agreement was entered into as a condition to
the willingness of Parent and Sub to enter into the Merger Agreement and to
increase the likelihood that the approval of the Issuer's stockholders required
in connection with the Merger will be obtained. See the response to Item 3 for a
more complete description of the Merger. Pursuant to the terms of the
Stockholders Agreement, any shares of capital stock of the Issuer or any other
securities convertible, exercisable or exchangeable into shares of capital stock
of the Issuer (in addition to the Additional Subject Shares) acquired by any
Stockholder after the date of the Stockholders Agreement and during the term of
the Stockholders Agreement (including through the exercise of any stock options,
warrants or similar instruments) will become subject to the Stockholders
Agreement. Accordingly, any such acquisition of shares of capital stock or of
such other securities of the Issuer by any Stockholder may result in Holdings,
Parent and Sub being deemed to acquire beneficial ownership of additional
securities of the Issuer.

          (c) Not applicable.

          (d) Upon consummation of the Merger, the sole director of Sub would

CUSIP NO. 961748 20 9

          (g) Prior to, and in contemplation of, the execution and delivery of
the Merger Agreement and the Stockholders Agreement, the Board of Directors of
the Issuer adopted an amendment to the By-Laws of the Issuer providing that the
provisions of Nevada Revised Statutes 'SS'SS' 78.378 et seq., relating to the
acquisition of a controlling interest in an issuing corporation shall not apply
to an acquisition of a controlling interest in the Issuer by Holdings, Parent,
Sub or any of their respective affiliates. Upon consummation of the Merger, the
Articles of Incorporation of Sub, as in effect immediately prior to the Merger,
would become the Articles of Incorporation of the Surviving Corporation until
thereafter changed or amended. Upon consummation of the Merger, the By-laws of
Sub, as in effect immediately prior to the Merger, would become the By-Laws of
the Surviving Corporation until thereafter changed or amended.

          (h) - (i) Upon consummation of the Merger, the Issuer Common Stock
would be delisted from The Nasdaq Bulletin Board Market and would become
eligible for termination of registration pursuant to Section 12(g)(4) of the
Exchange Act.

          (j) Other than as described above, none of Holdings, Parent and Sub
currently has any plan or proposals that relate to, or may result in, any of the
matters listed in Items 4(a) - (i) of Schedule 13D (although each of Holdings,
Parent and Sub reserves the right to develop such plans).

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER.

          (a)-(b) As a result of the Stockholders Agreement, Holdings, Parent
and Sub may be deemed to be the beneficial owners of the 3,245,648 Initial
Subject Shares. The 3,245,648 Initial Subject Shares consist of the following:
(1) 2,147,598 issued and outstanding shares of Issuer Common Stock, (2) 184,924
shares of Issuer Common Stock issuable upon exercise of options ("Options")
granted under the 1992 Directors' Stock Option Plan, as amended, and the 2000
Directors' Stock Option Plan of the Issuer, (3) 380,000 shares of Issuer Common
Stock issuable upon conversion of certain 10% Convertible Notes of the Issuer
("10% Convertible Notes") issued on December 23, 1999, (4) 247,500 shares of
Issuer Common Stock issuable upon conversion of certain 12% Convertible Notes of
the Issuer ("12% Convertible Notes") issued on February 13, 2001, and (5)
285,626 shares of Issuer Common Stock issuable upon exercise of certain warrants
of the Issuer ("Warrants") issued on various dates during the years 1999 and
2001. Based on (A) the Issuer's representation in the Merger Agreement that
there were 6,764,647 shares of Issuer Common Stock issued and outstanding at the
close of business on August 8, 2002, and (B) the representations of McKee and
William J. Preston in the Stockholders Agreement as to their beneficial
ownership of Issuer Common Stock, each Reporting Person may be deemed to
beneficially own 3,245,648 shares of Issuer Common Stock (1,098,050 shares of
which are issuable upon the exercise, conversion or exchange, as applicable, of
options, warrants and convertible notes of the Issuer which are currently
exercisable, exchangeable or convertible, as applicable, or will become
exercisable, exchangeable or convertible, as applicable, at any time within 60
days from the date of this Statement), and the Initial Subject Shares represent
approximately 41.28% of the Issuer Common Stock (assuming the exercise,
conversion or exchange of all options, warrants and convertible notes of the
Issuer described above). In addition, 90,000 Additional Subject Shares (all of
which are issuable pursuant to the exercise of Options of the Issuer that are
not currently exercisable and that will not become exercisable at any time
within 60 days from the date of this Statement) are also subject to the terms
and conditions of the Stockholders Agreement.

          Pursuant to the Stockholders Agreement, the Stockholders have agreed,
among other things: (1) to vote the Subject Shares in favor of (i) the adoption
of the Merger Agreement, (ii) the approval of the terms of the Merger Agreement,
and (iii) the approval of the Merger and each of the other transactions
contemplated by the Merger Agreement; (2) to vote the Subject Shares against (i)
any Takeover Proposal (as such term is defined in Section 5.02 of the Merger
Agreement), and (ii) any amendment of the Issuer's Articles of Incorporation or
Bylaws or other proposal, action or transaction involving the Issuer or any of
its subsidiaries or any of its stockholders, in each case that could reasonably
be expected to prevent or materially impede or delay the consummation of the
Merger or the other transactions contemplated by the Merger Agreement or the
consummation of the transactions contemplated by the Stockholders Agreement or
to dilute in any material respect the benefits to Parent of the Merger and the
other transactions contemplated by the Merger Agreement or the transactions
contemplated by the Stockholders

CUSIP NO. 961748 20 9

Agreement, or change in any manner the voting rights of the Issuer Common Stock;
(3) during the term of the Stockholders Agreement, not to sell, transfer,
pledge, assign, tender or otherwise dispose of any Subject Shares (or, except as
may be required under the Pledge Agreements (as defined in Item 4(d) of this
Statement)) consent to or permit any such action) or enter into any contract,
option or other arrangement with respect to the sale, transfer, pledge,
assignment or other disposition of such Subject Shares; (4) not to enter into
any voting agreement or arrangement in connection with any Takeover Proposal or
Frustrating Transaction (as such term is defined in Section 2(b) of the
Stockholders Agreement) with respect to any Subject Shares, other than pursuant
to the Stockholders Agreement; and (5) if, during the term of the Stockholders
Agreement (taking into account the penultimate sentence of Section 8 of the
Stockholders Agreement), Parent, Sub or one of their respective affiliates
offers (a "Parent Tender Offer") to purchase or otherwise acquire shares of
Issuer Common Stock in connection with a Parent Takeover Proposal (as defined in
Section 2(h) of the Stockholders Agreement), to tender the Subject Shares
pursuant to the terms of such Parent Tender Offer set forth in the acquisition
agreement in respect of the Parent Tender Offer, but in no event later than 10
business days after the date on which Parent, Sub (or such affiliate) commences
the Parent Tender Offer and to not withdraw any of the Subject Shares unless the
Parent Tender Offer is terminated or has expired, provided that Parent will
purchase the Subject Shares so tendered at a price per share equal to the Deal
Price or any higher price that may be paid in such offer.

          By their execution of the Stockholders Agreement, each Stockholder has
irrevocably appointed Parent and Christopher C. Cambria, Senior Vice President,
Secretary and General Counsel of Parent, and Michael T. Strianese, Senior Vice
President of Finance of Parent, in their respective capacities as designees of
Parent, and any individual who shall thereafter succeed to any such office of
Parent, and each of them individually, as his or her proxy and attorney-in-fact
(the "Attorney"). The name of each Stockholder and the number of Subject Shares
owned of record or beneficially by each Stockholder are set forth in Schedule A
to the Stockholders Agreement, which Stockholders Agreement is attached as
Exhibit 2 hereto. In exercising its right to vote the Subject Shares as proxy
and attorney-in-fact of the Stockholders, the Attorney's rights are limited to
voting the Subject Shares, or granting a consent or approval with respect to the
Subject Shares, (1) in favor of the adoption of the Merger Agreement and
approval of the terms thereof and of the Merger and each of the other
transactions contemplated by the Merger Agreement, (2) against any Takeover
Proposal or any Frustrating Transaction, and (3) otherwise in accordance with
the covenants of each Stockholder in Section 3 of the Stockholders Agreement.
The proxy granted in the Stockholders Agreement terminates upon the earlier of
the termination of the Stockholders Agreement or the date that is 24 months and
three days following the date of the granting of such proxy pursuant to the
Stockholders Agreement.

          In addition to the voting agreements and arrangements described above,
each Stockholder: (1) during the term of the Stockholders Agreement, has agreed,
at the request of Parent or Sub, to exercise, exchange or convert, as the case
may be, such number and type of convertible securities beneficially owned by
such Stockholder and then exercisable, exchangeable or convertible, as the case
may be, as Parent may request, in each case within two business days following
the later of (i) such request by Parent or Sub, and (ii) the last to occur of
(A) expiration or termination of any waiting period (and any extension thereof)
applicable to such sale and purchase under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended, or any other applicable competition,
merger control, antitrust or similar law or regulation and (B) the receipt of
any other regulatory approvals applicable to such sale and purchase, provided
that (x) Parent or Sub, as the case may be, shall purchase pursuant to the terms
and conditions set forth in clause (2) below all the shares of Issuer Common
Stock issued upon such exercise, exchange or conversion, as the case may be of
convertible securities, and (y) such Stockholder shall not be obligated so to
exercise, exchange or convert, as the case may be, any convertible security if
the exercise price, exchange price or conversion price, as the case may be, per
share of Issuer Common Stock in respect of such convertible security is above
the Deal Price; and (2) has granted Parent and Sub an option to purchase any and
all of the Subject Shares of such Stockholder, within four business days
following the later of (i) a request by Parent or Sub, as the case may be, to
purchase such Subject Shares (an "Option Exercise"), and (ii) the last to occur
of (A) expiration or termination of any waiting period (and any extension
thereof) applicable to such sale and purchase under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended, or any other applicable
competition, merger control, antitrust or similar law or regulation, and (B) the
receipt of any other regulatory approvals applicable to such sale and purchase,
for a purchase price per share equal to the Deal Price.

CUSIP NO. 961748 20 9

          Further, the Stockholders Agreement contains provisions (the "profit
provisions") pursuant to which if (a) (i) the Merger Agreement is terminated (A)
by either Parent or the Issuer due to the failure to obtain the approval of the
Issuer's stockholders to the Merger, (B) by Parent if (1) the Board of Directors
of the Issuer or any committee thereof shall withdraw or adversely modify, or
propose publicly or agree to withdraw or adversely modify, the recommendation or
declaration of advisability by such Board of Directors or any such committee of
the Merger Agreement or the Merger, or shall resolve or agree to take any such
action, or (2) the Board of Directors of the Issuer or any committee thereof
shall have failed to confirm its recommendation and declaration of advisability
of the Merger Agreement and the Merger within ten business days after a written
request by Parent that it do so, or (C) by the Issuer if the Board of Directors
of the Issuer shall have approved, and the Issuer shall concurrently with such
termination enter into, a definitive agreement providing for the implementation
of the transactions contemplated by a Takeover Proposal (as defined in Section
8.03(b)(i)(B) of the Merger Agreement) that such Board of Directors reasonably
determines in good faith by resolution duly adopted constitutes a Superior
Proposal (as defined in Section 5.02(a) of the Merger Agreement), (ii) an
Acquisition Agreement (as defined in Section 5.02(b) of the Merger Agreement)
with respect to any Takeover Proposal (as defined in Section 8.03(b)(i)(B) of
the Merger Agreement) is entered into by the Issuer or any of its subsidiaries
within 12 months after such termination of the Merger Agreement, and (iii) such
Takeover Proposal (as defined in Section 8.03(b)(i)(B) of the Merger Agreement)
is consummated within 24 months of such termination, or (b) a Parent Takeover
Proposal (as defined in Section 2(h)(vi) of the Stockholders Agreement) made by
Parent (including any amendment of the Merger Agreement) which provides for
Transaction Consideration (as defined in Section 2(h)(iii) of the Stockholders
Agreement) in excess of the Deal Price, is consummated, then each Stockholder is
required to pay to Parent the amount in cash equal to such Stockholder's Profit
(as such term is defined in Section 2(h)(iii) of the Stockholders Agreement).

          The Stockholders Agreement terminates upon the earlier of (a) such
date and time as the Merger shall become effective in accordance with the terms
of the Merger Agreement and (b) the date of termination of the Merger Agreement
if the Merger Agreement is terminated according to its terms; provided, however,
that if the Merger Agreement is terminated as provided in clauses (a)(i)(A),
(a)(i)(B) or (a)(i)(C) of the immediately preceding paragraph, then (i) Section
2(h) of the Stockholders Agreement (relating to the profit provisions), as well
as other Sections of the Stockholders Agreement, shall continue in full force
and effect for the duration of the Residual Period, (ii) the option granted
under the Stockholders Agreement that had been exercised prior to termination of
the Merger Agreement shall continue in full force and effect until the sale,
transfer and delivery of the Subject Shares with respect to such option have
been effected, and (iii) the provisions of Section 2(j) of the Stockholders
Agreement (relating to an offer by Parent or any of its affiliates to purchase
or otherwise acquire shares of Issuer Common Stock in connection with a Parent
Takeover Proposal) shall continue in full force and effect until such offer is
terminated or has expired. The "Residual Period" means the period beginning on
the date of termination of the Merger Agreement and ending 12 months thereafter;
provided, however, that if within such 12 month-period the Issuer or any of its
subsidiaries enters into an Acquisition Agreement, then the Residual Period
shall not end until the date that is 24 months and three days after the
termination of the Merger Agreement.

          By virtue of the Stockholders Agreement, Holdings, Parent and Sub may
be deemed to have shared power to vote and dispose of all the Subject Shares.
Beneficial ownership of such Subject Shares is expressly disclaimed.

          The descriptions of the Merger Agreement and the Stockholders
Agreement contained herein are qualified in their entirety by reference to such
agreements, which agreements are attached hereto as Exhibits 1 and 2,
respectively.

          (c) None of Holdings, Parent and Sub or, to the knowledge of Holdings,
Parent or Sub, any person named in Appendix A-1 or Appendix A-2, has effected
any transaction in the Issuer Common Stock during the past 60 days.

          (d) McKee has pledged 750,000 Initial Subject Shares (the "Pledged
Shares") held by him to Stillwater National Bank and Trust Company, Stillwater,

          Further, immediately prior to, and in contemplation of, the execution

has consented to the execution, delivery and performance of the Stockholders
Agreement by all the parties thereto and waived any provision of any instrument
or agreement to which the Bank is a party (including the Credit Facility Pledge
Agreement and the Personal Loan Pledge Agreement) that conflicts with, or
restricts the ability of the parties to the Stockholders Agreement to execute,
deliver or perform, the Stockholders Agreement or any of the transactions
contemplated thereby. In addition, the Letter Agreement provides that in

(in the case of an Option Exercise), the consummation of the Parent Tender Offer
(in the case of the consummation of the Parent Tender Offer) or the effective

Pledged Shares (in the case of the consummation of the Parent Tender Offer or
the Merger, as the case may be) shall be released from the pledge pursuant to
the Pledge Agreements and from any other share encumbrance in favor of the Bank
without any further action by the Bank or McKee, (2) prior to the consummation
of the purchase and sale of the Pledged Option Shares (in the case of an Option
Exercise), or prior to the date that is 10 business days after the date on which
Parent or one of its affiliates commences the Parent Tender Offer (in the case
of the consummation of the Parent Tender Offer), or prior to the effective time
of the Merger (in the case of the consummation of the Merger), as the case may
be, the Bank will deliver to Parent or Sub (or their respective designees or
assignees), as the case may be, all certificates in its possession representing
the Pledged Option Shares (in the case of an Option Exercise) or the Pledged
Shares (in the case of the consummation of the Parent Tender Offer or the
Merger, as the case may be), as the case may be, duly endorsed in blank for
transfer to Parent or Sub (or their respective designee(s) or assignee(s)), as
the case may be, or accompanied by stock powers for the Pledged Option Shares
(in the case of an Option Exercise) or the Pledged Shares (in the case of the
consummation of the Parent Tender Offer or the Merger, as the case may be), as
the case may be, duly executed in blank, in proper form for transfer; (3)
effective immediately prior to the consummation of the purchase and sale of the
Option Shares (in the case of an Option Exercise), the consummation of the

respect of the Option Shares (in the case of an Option Exercise) or the Pledged
Shares (in the case of the consummation of the Parent Tender Offer or the
Merger, as the case may be), as the case may be; and (4) the Bank shall apply
such purchase price as follows: first, to the payment of all amounts owed by
McKee to the Bank under the Personal Loan Pledge Agreement; and second, any
remaining portion of such purchase price shall be paid over to McKee.

          The Letter Agreement expressly provides that Parent and Sub are
third-party beneficiaries of the Letter Agreement and the Letter Agreement may
not be amended without the prior written consent of L-3 and Sub.

     AGREEMENT AND PLAN OF MERGER dated as of August 8, 2002 (this "Agreement"),
among L-3 COMMUNICATIONS CORPORATION, a Delaware corporation having its
principal office at 600 Third Avenue, New York, NY 10016 ("Parent"), BLUE
ACQUISITION CORP., a Nevada corporation and a wholly owned Subsidiary of Parent
having its principal office at 600 Third Avenue, New York, NY 10016 ("Sub"), and
WESTWOOD CORPORATION, a Nevada corporation having its principal office at 12402
E. 60th Street, Tulsa, OK 74146 (the "Company"). Capitalized and other defined
terms shall have the respective meanings set forth or referred to in Section
9.03.

     WHEREAS, the Board of Directors of each of the Company and Sub deems it in
the best interests of their respective stockholders to consummate the merger of
Sub with and into the Company in which the Company would become a wholly owned
Subsidiary of Parent (the "Merger"), on the terms and subject to the conditions
set forth in this Agreement, and such Boards of Directors have approved this
Agreement and declared its advisability (and, in the case of the Board of
Directors of the Company, recommended that this Agreement be adopted by the
Company's stockholders);

     WHEREAS, simultaneously with the execution and delivery of this Agreement
and as a condition and inducement to Parent and Sub to enter into this
Agreement, Parent, Sub, the Company and certain stockholders of the Company are
entering into a stockholders agreement (the "Stockholders Agreement"), pursuant
to which, among other things, such stockholders are agreeing to vote to approve
this Agreement and to take certain other actions in furtherance of the Merger,
in each case upon the terms and subject to the conditions set forth therein;

     WHEREAS, Parent, Sub and the Company desire to make certain
representations, warranties, covenants and agreements in connection with the
Merger and to prescribe various conditions to the Merger;

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

                                    ARTICLE I
                                   THE MERGER

     SECTION 1.01 Effective Time of the Merger. As soon as practicable on or
after the Closing Date, the parties shall (a) file articles of merger (the
"Articles of Merger") in such form as is required by, and executed and
acknowledged in accordance with, the relevant provisions of the Nevada Revised
Statutes (the "NRS"), and (b) make all other filings or recordings required
under the NRS to effect the Merger. The Merger shall become effective at such
time as the Articles of Merger are duly filed with the Secretary of State of the
State of Nevada or at such subsequent time as Parent and the Company shall agree
and specify in the Articles of Merger (the date and time the Merger becomes
effective being the "Effective Time").

     SECTION 1.02 Closing. The closing of the Merger (the "Closing") will take
place at 11:00 a.m., New York time, on a date to be specified by the parties,
which shall be not later than the second business day after satisfaction or
waiver of the conditions set forth in Article VII


                                        5







(the "Closing Date"), at the offices of Proskauer Rose LLP, 1585 Broadway, New
York, New York 10036-8299, unless another time, date or place is agreed to in
writing by Parent and the Company.

     SECTION 1.03 Effect of the Merger. At the Effective Time, Sub shall be
merged with and into the Company, the separate corporate existence of Sub shall
cease and the Company shall continue as the surviving corporation (the
"Surviving Corporation"). The Merger shall have the effects set forth in Section
92A.250 of the NRS.

     SECTION 1.04 Articles of Incorporation and Bylaws.

          (a) The Articles of Incorporation of Sub, as in effect immediately
prior to the Effective Time, shall be the Articles of Incorporation of the
Surviving Corporation until thereafter changed or amended as provided therein or
by Applicable Law.

          (b) The Bylaws of Sub, as in effect immediately prior to the Effective
Time, shall be the Bylaws of the Surviving Corporation until thereafter changed
or amended as provided therein or by Applicable Law.

     SECTION 1.05 Directors. The directors of Sub immediately prior to the
Effective Time shall be the directors of the Surviving Corporation until their
respective successors are duly elected and qualified, unless they earlier die,
resign or are removed, as the case may be.

     SECTION 1.06 Officers. The officers of Sub immediately prior to the
Effective Time shall be the officers of the Surviving Corporation until their
respective successors are duly elected and qualified, unless they earlier die,
resign or are removed, as the case may be.

                                   ARTICLE II
                            CONVERSION OF SECURITIES

     SECTION 2.01 Conversion of Capital Stock. At the Effective Time, by virtue
of the Merger and without any action on the part of the holders of any shares of
Common Stock of the Company, par value $0.003 per share (the "Company Common
Stock"), or any shares of capital stock of Sub:

          (a) Capital Stock of Sub. Each issued and outstanding share of common
stock, par value $0.003 per share, of Sub shall be converted into and become one
fully paid and nonassessable share of common stock, par value $0.003 per share,
of the Surviving Corporation.

          (b) Cancellation of Treasury Stock and Parent-Owned Stock. All shares
of Company Common Stock that are owned by the Company as treasury stock, by any
Subsidiary of the Company, by Parent or by Sub immediately prior to the
Effective Time, shall automatically be cancelled and retired and shall cease to
exist and no consideration shall be delivered 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


                                        6







shares to be cancelled and retired in accordance with Section 2.01(b) and the
Appraisal Shares) shall be converted into the right to receive $2.30 in cash,
without interest (such $2.30 amount to be appropriately adjusted to take into
account any stock dividend, split, reverse split, combination, reclassification,
merger, recapitalization, share exchange or other similar transaction occurring
after the date hereof and prior to the Effective Time and involving the
Company's capital stock) (the "Merger Consideration"). At the Effective Time,
all such shares of Company Common Stock shall no longer be outstanding and shall
automatically be cancelled and shall cease to exist, and each holder of a
certificate that immediately prior to the Effective Time represented any such
shares (a "Certificate") shall cease to have any rights with respect thereto,
except the right to receive the Merger Consideration. The right of any holder of
any share of Company Common Stock to receive the Merger Consideration shall be
subject to and reduced by the amount of any withholding that is required under
applicable tax law.

          (d) Appraisal Rights. Notwithstanding anything in this Agreement to
the contrary, shares (the "Appraisal Shares") of Company Common Stock issued and
outstanding immediately prior to the Effective Time that are held by any holder
who is entitled to demand and properly demands appraisal of such shares pursuant
to, and who complies in all respects with, the provisions of Sections 92A.300
through 92A.500, inclusive, of the NRS (the "Appraisal Rights Sections") shall
not be converted into the right to receive the Merger Consideration as provided
in Section 2.01(c), but instead such holder shall be entitled to payment of the
fair value of such shares in accordance with the provisions of the Appraisal
Rights Sections. At the Effective Time, the Appraisal Shares shall no longer be
outstanding and shall automatically be cancelled and shall cease to exist, and
each holder of Appraisal Shares shall cease to have any rights with respect
thereto, except the right to receive the fair value of such shares in accordance
with the provisions of the Appraisal Rights Sections. Notwithstanding the
foregoing, if any such holder fails to perfect or otherwise waives, withdraws or
loses the right to appraisal under the Appraisal Rights Sections, or a court of
competent jurisdiction determines that such holder is not entitled to the relief
provided by the Appraisal Rights Sections, then the right of such holder to be
paid the fair value of such holder's Appraisal Shares under the Appraisal Rights
Sections shall cease and such Appraisal Shares shall be deemed to have been
converted at the Effective Time into, and shall have become, the right to
receive the Merger Consideration as provided in Section 2.01(c). The Company
shall serve prompt notice to Parent of any demands for appraisal of any shares
of Company Common Stock, withdrawals of such demands and any other instruments
served pursuant to the NRS received by the Company, and Parent shall have the
right to participate in and direct all negotiations and proceedings with respect
to such demands. The Company shall not, without the prior written consent of
Parent, make any payment with respect to, or settle or offer to settle, any such
demands, or agree to do or commit to do any of the foregoing.

     SECTION 2.02 Exchange of Certificates.

          (a) Paying Agent. Prior to the Effective Time, Parent shall designate
a bank or trust company to act as agent for the payment of the Merger
Consideration upon surrender of Certificates (the "Paying Agent"). From time to
time after the Effective Time, Parent shall make available, or cause the
Surviving Corporation to make available, to the Paying Agent funds in such
amounts and at such times necessary for the payment of the Merger Consideration
pursuant to Section 2.01(c) upon surrender of Certificates, it being understood
and agreed that any and all


                                        7







interest earned on funds made available to the Paying Agent pursuant to this
Agreement shall be turned over to Parent.

          (b) Exchange Procedure. As soon as reasonably practicable after the
Effective Time, the Paying Agent shall mail to each holder of record of a
Certificate (i) a form of letter of transmittal (which shall specify that
delivery shall be effected, and risk of loss and title to the Certificates held
by such person shall pass, only upon proper delivery of the Certificates to the
Paying Agent and shall be in a form and have such other provisions as Parent may
reasonably specify (including a Form W-9)), and (ii) instructions for use in
effecting the surrender of the Certificates in exchange for the Merger
Consideration. Upon surrender of a Certificate for cancellation to the Paying
Agent or to such other agent or agents as may be appointed by Parent, together
with such letter of transmittal, duly completed and validly executed, and such
other documents as may reasonably be required by the Paying Agent, the holder of
such Certificate shall be entitled to receive in exchange therefor the amount of
cash into which the shares formerly represented by such Certificate shall have
been converted pursuant to Section 2.01(c), and the Certificate so surrendered
shall forthwith be cancelled. In the event of a transfer of ownership of shares
that is not registered in the stock transfer books of the Company, payment may
be made to a person other than the person in whose name the Certificate so
surrendered is registered if such Certificate shall be properly endorsed or
otherwise be in proper form for transfer and the person requesting such payment
shall pay any transfer or other taxes required by reason of the payment to a
person other than the registered holder of such Certificate or establish to the
satisfaction of the Surviving Corporation that such tax has been paid or is not
applicable. No interest shall be paid or shall accrue on the cash payable upon
surrender of any Certificate.

          (c) No Further Ownership Rights in Company Common Stock. All cash paid
upon the surrender of a Certificate 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 of Company Common Stock formerly represented by such
Certificate. At the close of business on the day on which the Effective Time
occurs the stock transfer books of the Company shall be closed, and there shall
be no further registration of transfers on the stock transfer books of the
Surviving Corporation of the shares that were outstanding immediately prior to
the Effective Time. If, after the Effective Time, Certificates are presented to
the Surviving Corporation or the Paying Agent for transfer or any other reason,
they shall be cancelled and exchanged as provided in this Article II.

          (d) No Liability. None of Parent, Sub, the Company and the Paying
Agent shall be liable to any person in respect of any cash delivered to a public
official pursuant to any applicable abandoned property, escheat or similar law.
If any Certificates shall not have been surrendered prior to two years after the
Effective Time (or immediately prior to such earlier date on which any Merger
Consideration would otherwise escheat to or became the property of any Federal,
state or local, domestic or foreign, government or any court, administrative
agency or commission or other governmental or regulatory authority or agency,
domestic or foreign (each, a "Governmental Entity")), any such Merger
Consideration in respect thereof shall, to the extent permitted by Applicable
Law, become the property of the Surviving Corporation, free and clear of all
claims or interest of any person previously entitled thereto.

          (e) 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


                                        8







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 shall pay the Merger
Consideration in respect of such lost, stolen or destroyed Certificate.

          (f) Withholding Rights. Parent, the Surviving Corporation or the
Paying Agent shall be entitled to deduct and withhold from the Merger
Consideration otherwise payable to any holder of shares of Company Common Stock
pursuant to this Agreement such amounts as Parent, the Surviving Corporation or
the Paying Agent 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 withheld and paid over to the appropriate taxing authority by
Parent, the Surviving Corporation or the Paying Agent, such withheld amounts
shall be treated for all purposes of this Agreement as having been paid to the
holder of the shares of Company Common Stock in respect of which such deduction
and withholding was made by Parent, the Surviving Corporation or the Paying
Agent.

     SECTION 2.03 Stock Options; Warrants; Convertible Notes. As soon as
practicable following the date of this Agreement and prior to the Closing, the
Company shall take such actions (including obtaining any required Consents),
which actions shall be satisfactory to Parent, as may be required to effect the
following:

          (a) Stock Options. At the Effective Time, all outstanding and
unexpired Stock Options (regardless of whether or not such options have vested
and regardless of whether the exercise prices per share of Company Common Stock
are below, at or above the Merger Consideration) shall be cancelled on terms and
conditions satisfactory to Parent. Each holder of a cancelled Stock Option shall
be entitled to receive, in consideration for the cancellation of such Stock
Option, an amount in cash equal to the product of (i) the number of shares of
Company Common Stock previously subject to such Stock Option and (ii) the
excess, if any, of the Merger Consideration over the exercise price per share of
Company Common Stock previously subject to such Stock Option in effect
immediately prior to such cancellation (such payment to be net of taxes and
other amounts required by Applicable Law to be withheld with respect thereto).
Payment to such holder under this Section 2.03(a) shall be made without interest
thereon, upon surrender of the certificate or other document evidencing such
Stock Option to the Surviving Corporation. Delivery of any cash payment under
this Section 2.03(a) to a holder of cancelled Stock Options shall be conditioned
upon receipt by Parent of a waiver of all of such holder's right, title and
interest in and to his or her Stock Options.

          (b) Warrants. At the Effective Time, all outstanding and unexpired
Warrants (regardless of whether or not such Warrants are then exercisable and
regardless of whether the exercise prices per share of Company Common Stock are
below, at or above the Merger Consideration) shall be cancelled on terms and
conditions satisfactory to Parent. Each holder of a cancelled Warrant shall be
entitled to receive, in consideration for the cancellation of such Warrant, an
amount in cash equal to the product of (i) the number of shares of Company
Common Stock previously subject to such Warrant and (ii) the excess, if any, of
the Merger Consideration over the exercise price per share of Company Common
Stock previously subject


                                        9







to such Warrant in effect immediately prior to such cancellation (such payment
to be net of taxes and other amounts required by Applicable Law to be withheld
with respect thereto). Payment to such holder under this Section 2.03(b) shall
be made without interest thereon, upon surrender of such Warrant to the
Surviving Corporation. Delivery of any cash payment under this Section 2.03(b)
to a holder of a Warrant shall be conditioned upon receipt by Parent of a waiver
of all of such holder's right, title and interest in and to his or her Warrant.

          (c) Convertible Notes. The Company shall use its best efforts to cause
all outstanding Convertible Notes to be converted in full into shares of Company
Common Stock in accordance with their respective terms and to cease to be issued
and outstanding, in each case prior to the Effective Time.

          (d) Termination of Plans. As of the Effective Time, all Company Stock
Plans, and the relevant provisions of all Benefit Agreements and other Contracts
shall terminate on terms and conditions satisfactory to Parent so that on and
after the Effective Time no current or former employee, director, consultant or
other Person shall have any right or option to acquire, hold or transfer shares
of Company Common Stock or any other equity interests in the Company or any of
its Subsidiaries under any Company Stock Plan, Benefit Agreement or other
Contract.

                                   ARTICLE III
                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

     The Company represents and warrants to Parent and Sub as follows:

     SECTION 3.01 Organization, Qualification and Corporate Power.

          (a) The Company and each of its Subsidiaries is a corporation duly
organized, validly existing and in good standing under the laws of its
jurisdiction of incorporation and is duly qualified or licensed to conduct
business and is in good standing under the laws of each jurisdiction set forth
in Section 3.01(a) of the Company Disclosure Schedule, which are all the
jurisdictions where the character of the properties owned, leased or operated by
it or the nature of its activities makes such qualification or licensing and
requirement to be in good standing necessary, except for any such failures to be
qualified and in good standing that could not reasonably be expected to have,
individually or in the aggregate, a Company Material Adverse Effect. The Company
and each of its Subsidiaries has all requisite corporate power and authority to
carry on the business in which it is now engaged and to own, lease and use the
properties now owned, leased or used by it.

     For purposes of this Agreement: (i) "Company Disclosure Schedule" means the
disclosure schedule delivered by the Company to Parent prior to or
simultaneously with the execution of this Agreement; and (ii) "Company Material
Adverse Effect" means any event, occurrence, fact, condition, change, effect or
circumstance that (A) is, or that could reasonably be expected to be, materially
adverse to the assets, business, prospects, financial condition, operations,
properties, liabilities or results of operations of the Company and its
Subsidiaries, taken as a whole (other than changes that are the result of
economic factors affecting the economy as a whole or changes that are the result
of factors generally affecting the industry or specific markets in which the
Company competes), or (B) materially impairs or delays the ability


                                       10







of the Company to consummate the transactions contemplated by, or to perform its
other obligations under, this Agreement or the Stockholders Agreement. Without
limiting the foregoing and for the avoidance of doubt, a "Company Material
Adverse Effect" would be deemed to exist in the event of (1) a ruling, decision
or order (whether or not final or nonappealable) that is adverse to the Company
or any of its Subsidiaries by a Governmental Entity affecting Contract No.
DAAB07-01-D-F201 between the U.S. Army and a Subsidiary of the Company issued
pursuant to Army Solicitation No. DAAB07-01-R-C402 (as may be amended from time
to time, the "TQG Contract") in connection with the facts alleged by the
plaintiff in matter of Engineered Electric Company d/b/a Fermont v. The United
States of America, No. 02-757C, pending in the United States Court of Federal
Claims, or (2) a decision by the Contracting Officer in respect of the TQG
Contract materially impairing the value of the TQG Contract to the Company or
any of its Subsidiaries.

          (b) The Company has delivered to Parent complete and correct copies of
its Articles of Incorporation and its Bylaws and the articles of incorporation
and bylaws (or similar organizational documents) of each of its Subsidiaries, in
each case as amended to the date of this Agreement. The Company has made
available to Parent and its representatives true and complete copies of the
minutes (or in the case of draft minutes, the most recent drafts thereof) of all
meetings of the stockholders, the Board of Directors and each committee of the
Board of Directors of the Company and each of its Subsidiaries held since May 1,
1996. Neither the Company nor any of its Subsidiaries is in default under or in
violation of any provision of its articles of incorporation or bylaws (or
similar organizational documents). The provisions of Sections 78.378 to 78.3793,
inclusive, of the NRS relating to "Acquisition of Controlling Interest" and
Sections 78.411 to 78.444, inclusive, of the NRS relating to "Combinations with
Interested Stockholders" are inapplicable to this Agreement, the Stockholders
Agreement and the transactions contemplated hereby and thereby (including the
Merger) as a result of the Company's actions or otherwise.

     SECTION 3.02 Capital Structure.

          (a) The authorized capital stock of the Company consists of 20,000,000
shares of Company Common Stock and 5,000,000 of the Company's Preferred Stock,
par value $0.001 per share (the "Company Preferred Stock"). At the close of
business on August 8, 2002: (i) 6,764,647 shares of Company Common Stock
(excluding treasury shares) were issued and outstanding, none of which were held
by any Subsidiary of the Company; (ii) 127,000 shares of Company Common Stock
were held by the Company in its treasury; (iii) no shares of Company Preferred
Stock were issued and outstanding; (iv) options to acquire 1,044,772 shares of
Company Common Stock from the Company were issued and outstanding (the "Stock
Options") pursuant to (A) the 1992 Incentive and Nonqualified Stock Option Plan
of the Company (as amended), the 1992 Directors' Stock Option Plan (as amended)
and the 2000 Directors' Stock Option Plan (collectively, the "Company Stock
Plans") as listed on Section 3.02(a)(iv)(A1-A3) of the Company Disclosure
Schedule, and (B) written employment agreements listed on Section 3.02(a)(iv)(B)
of the Company Disclosure Schedule and previously provided in true and complete
form to Parent or its counsel, (v) warrants to acquire up to 840,002 shares of
Company Common Stock from the Company pursuant to the stock purchase warrants
listed on Section 3.02(a)(v) of the Company Disclosure Schedule and previously
provided in true and complete form to Parent or its counsel (the "Warrants")
were issued and outstanding; (vi) 1,000,000 shares


                                       11







of Company Common Stock were issuable upon conversion of the 10% Convertible
Subordinated Notes listed on Section 3.02(a)(vi) of the Company Disclosure
Schedule and previously provided in true and complete form to Parent or its
counsel (the "1999 Notes"); (vii) 880,000 shares were issuable upon conversion
of the 12% Convertible Subordinated Notes listed in Section 3.02(a)(vii) of the
Company Disclosure Schedule and previously provided in true and complete form to
Parent or to counsel (together with the 1999 Notes, the "Convertible Notes");
and (viii) (A) 288,153 shares of Company Common Stock were reserved and
available for issuance pursuant to the 1992 Incentive and Nonqualified Stock
Option Plan of the Company (as amended), (B) 189,330 shares of Company Common
Stock were reserved and available for issuance pursuant to the 1992 Directors'
Stock Option Plan (as amended), and (C) 250,000 shares of Company Common Stock
were reserved and available for issuance pursuant to the 2000 Directors' Stock
Option Plan. Schedule 3.02(a) of the Company Disclosure Schedule sets forth a
complete and correct list, as of the close of business on August 8, 2002, of all
outstanding stock options or other rights to purchase or acquire Company Common
Stock granted under the Company Stock Plans, the Warrants, the Convertible
Notes, written employment agreements or otherwise, including: (1) all
outstanding Stock Options, the number of shares of Company Common Stock subject
to each Stock Option, the grant dates and exercise and vesting schedule of each
such Stock Option and the names of the holders of each Stock Option; (2) all
outstanding Warrants, the number of shares of Company Common Stock issuable
under each Warrant, the issue dates and exercise prices and exercise schedule of
each such Warrant and the names of the holders of each Warrant; and (3) all
outstanding Convertible Notes, the number of shares of Company Common Stock
issuable under each Convertible Note, the issue dates and conversion prices and
conversion schedule of each such Convertible Note and the names of the holders
of each Convertible Note. Other than the Stock Options, the Warrants and the
Convertible Notes, there are no outstanding rights of any person to receive
Company Common Stock under the Company Stock Plans, under any Contract or
otherwise, or on a deferred basis or otherwise.

          (b) As of the close of business on August 8, 2002, there were
outstanding Stock Options, Warrants and Convertible Notes to purchase 3,716,456
shares of Company Common Stock with exercise or conversion prices, as the case
may be, on a per share basis lower than the Merger Consideration, and the
weighted average exercise or conversion price, as the case may be, of such Stock
Options, Warrants and Convertible Notes was equal to $1.07. As of the close of
business on August 8, 2002, there were outstanding Stock Options, Warrants and
Convertible Notes to purchase 48,318 shares of Company Common Stock with
exercise or conversion prices, as the case may be, on a per share basis equal to
or higher than the Merger Consideration, and the weighted average exercise or
conversion price, as the case may be, of such Stock Options, Warrants and
Convertible Notes was equal to $2.39.

          (c) Except as set forth in Section 3.02(a) of the Company Disclosure
Schedule, as of the close of business on August 8, 2002, no shares of capital
stock of or other equity or voting interests in the Company, or options,
warrants, convertible notes or other rights to acquire or receive any such stock
or interests were issued, reserved for issuance or outstanding, and neither the
Company nor any of its Subsidiaries is a party to any agreement relating to any
such issuance. Since August 8, 2002, (i) there have been no issuances by the
Company of shares of capital stock of or other equity or voting interests in the
Company other than issuances of shares of Company Common Stock pursuant to the
exercise or conversion, as the case may be, of Stock Options, Warrants or
Convertible Notes, in each case outstanding on


                                       12







such date as required by their terms as in effect on the date of this Agreement,
and (ii) there have been no issuances by the Company of options, warrants,
convertible notes or other rights to acquire shares of capital stock or other
equity or voting interests from the Company. There are no outstanding stock
appreciation rights or other rights that are linked in any way to the price of
the Company Common Stock or the value of the Company, any Subsidiary of the
Company or any part of the Company or any such Subsidiary.

          (d) All outstanding shares of capital stock of the Company are, and
all shares that may be issued pursuant to the Stock Options, the Warrants and
the Convertible Notes will be, when issued in accordance with the terms thereof,
duly authorized, validly issued, fully paid and nonassessable and not subject to
preemptive rights or, to the Company's or any of its Subsidiaries knowledge, any
other Share Encumbrance, except as set forth in Section 3.02(d) of the Company
Disclosure Schedule. Except for the Convertible Notes, there are no bonds,
debentures, notes or other indebtedness of the Company or any of its
Subsidiaries, and no securities or other instruments or obligations of the
Company or any of its Subsidiaries the value of which is in any way based upon
or derived from any capital or voting stock of the Company, having the right to
vote (or convertible or exercisable into, or exchangeable for, securities having
the right to vote) on any matters on which stockholders of the Company may vote.
Except as set forth above, there are no securities, options, warrants,
convertible notes, calls, rights, obligations, arrangements, understandings or
Contracts of any kind to which the Company or any of its Subsidiaries is a
party, or by which the Company or any of its Subsidiaries is bound, obligating
the Company or any of its Subsidiaries to issue, deliver or sell, or cause to be
issued, delivered or sold, additional shares of capital stock of, or other
equity or voting interests in, or securities convertible or exercisable into, or
exchangeable or exercisable for, shares of capital stock of or other equity or
voting interests in the Company or any of its Subsidiaries or obligating the
Company or any of its Subsidiaries to issue, grant, extend or enter into any
such security, option, warrant, convertible note, call, right, obligation,
arrangement, understanding or Contract. Each Stock Option intended to qualify as
an "incentive stock option" under Section 422 of the Code so qualifies and the
exercise price of each other Stock Option is not less than the fair market value
of a share of Company Common Stock as determined on the date of grant of such
Stock Option. As of the date of this Agreement, (i) the Subject Shares (as such
term is defined in the Stockholders Agreement) represent approximately 41% of
the shares of Company Common Stock outstanding (assuming the exercise, exchange
or conversion, as applicable, of all outstanding convertible securities of the
Company (including the Stock Options, the Warrants and the Convertible Notes)
which are currently exercisable, exchangeable or convertible, as applicable, or
will become exercisable, exchangeable or convertible, as applicable, at any time
within 60 days from the date of this Agreement), and (ii) the Subject Shares
that constitute shares of Company Common Stock represent approximately 31% of
the shares of Company Common Stock outstanding . There are not any outstanding
contractual obligations of the Company or any of its Subsidiaries to (A)
repurchase, redeem or otherwise acquire any shares of capital stock of the
Company or any of its Subsidiaries, or (B) vote or dispose of any shares of the
capital stock of any of its Subsidiaries. The Company is not a party to any
voting or other stockholders agreements with respect to any shares of the
capital stock of or other equity or voting securities in the Company or any of
its Subsidiaries and, to the knowledge of the Company or any of its
Subsidiaries, as of the date of this Agreement, there are no irrevocable proxies
and no voting or other stockholders agreements with respect to any shares of the
capital stock of or other equity or voting interests in the Company or any of
its Subsidiaries.


                                       13







          (e) As of the date hereof, the outstanding Indebtedness of the Company
and its Subsidiaries is as set forth on Section 3.02(e) of the Company
Disclosure Schedule.

     SECTION 3.03 Subsidiaries.

          (a) Section 3.03 of the Company Disclosure Schedule lists each
Subsidiary of the Company. All the outstanding shares of capital stock of or
other equity or voting interests in each such Subsidiary are owned by the
Company, by another wholly owned Subsidiary of the Company or by the Company and
another wholly owned Subsidiary of the Company, free and clear of any liens,
encumbrances, hypothecations, rights of others, charges, adverse claims or
interests, title defects, pledges, voting trusts or similar arrangements,
limitations on voting rights, options, restrictions on transfer, proxies, title
retention agreements, securityholder agreements or other similar restrictions or
limitations, (collectively, "Share Encumbrances"), excepting only restrictions
on the subsequent transfer of such shares imposed under applicable securities
laws. Except for the capital stock of or other equity or voting interests in its
Subsidiaries, the Company does not own, directly or indirectly, any capital
stock of or other equity or voting interests in any corporation, partnership,
joint venture, association or other entity.

          (b) Those Subsidiaries that are Roflan Associates, Inc., a
Massachusetts corporation, and Peter Gray Corporation, a Massachusetts
corporation, are not engaged in any business and do not conduct any activity.

     SECTION 3.04 Authority; Noncontravention.

          (a) The Company has the requisite corporate power and authority to
execute and deliver this Agreement and the Stockholders Agreement, to consummate
the transactions contemplated by this Agreement and the Stockholders Agreement,
subject, in the case of the Merger, to obtaining the Stockholder Approval, and
to comply with the provisions of this Agreement and the Stockholders Agreement.
The execution and delivery of this Agreement and the Stockholders Agreement by
the Company, the consummation by the Company of the transactions contemplated by
this Agreement and the Stockholders Agreement and the compliance by the Company
with the provisions of this Agreement and the Stockholders Agreement have been
duly authorized by all necessary corporate action on the part of the Company and
no other corporate proceedings on the part of the Company are necessary to
authorize this Agreement or the Stockholders Agreement or to consummate the
transactions contemplated by this Agreement or the Stockholders Agreement,
subject, in the case of the Merger, to obtaining the Stockholder Approval. Each
of this Agreement and the Stockholders Agreement has been duly executed and
delivered by the Company and, assuming the due authorization, execution and
delivery by Parent and Sub, constitutes a valid and binding obligation of the
Company, enforceable against the Company in accordance with its terms (except as
enforceability may be limited by bankruptcy, insolvency, reorganization,
moratorium or other similar laws).

          (b) The Board of Directors of the Company, at a meeting duly called
and held at which all of the directors of the Company were present either in
person or by telephone, duly and with the unanimous approval of those directors
in attendance adopted resolutions (i) approving and declaring advisable the
Merger, this Agreement and the transactions contemplated


                                       14







by this Agreement, (ii) declaring that it is in the best interests of the
Company's stockholders that the Company enter into this Agreement and consummate
the Merger on the terms and subject to the conditions set forth in this
Agreement, (iii) declaring that the consideration to be paid to the Company's
stockholders in the Merger is fair to such stockholders, (iv) directing that
this Agreement be submitted to a vote at a meeting of the Company's stockholders
to be held as promptly as reasonably practicable following the date of this
Agreement, (v) recommending that such stockholders adopt this Agreement, and
(vi) approving the Stockholders Agreement and the transactions contemplated
thereby, which resolutions have not been subsequently rescinded, modified or
withdrawn in any way except as is expressly and specifically permitted under
Section 5.02(b).

          (c) The execution and delivery of this Agreement and the Stockholders
Agreement and the consummation of the transactions contemplated hereby and
thereby and compliance by the Company with the provisions of this Agreement do
not and will not conflict with, or result in any violation or breach of, or
default (with or without notice or lapse of time, or both) under, or give rise
to a right of, or result in, termination, cancellation or acceleration of any
obligation or to a loss of a material benefit under, or result in the creation
of any mortgage, pledge, security interest, encumbrance, charge, lien,
hypothecation, adverse claim or interest, easement, encroachment, title defect,
title retention agreement or other similar restriction or limitation (whether
arising by contract, by operation of law or otherwise) (collectively, "Liens")
in or upon any of the properties or assets of the Company or any of its
Subsidiaries under, or give rise to any increased, additional, accelerated or
guaranteed rights or entitlements under, any provision of: (i) the Articles of
Incorporation or Bylaws of the Company or the articles of incorporation or
bylaws (or similar organizational documents) of any of its Subsidiaries; (ii)
any loan or credit agreement (including the Credit Facility), bond, debenture,
note (including the Convertible Notes), mortgage, indenture, guarantee, lease or
other contract, commitment, agreement, instrument, arrangement, understanding,
obligation, undertaking, permit, permission, concession, franchise, license or
sublicense, whether oral or written (each, including all amendments thereof and

Subsidiaries is a party or any of their respective properties or assets is
subject; or (iii) subject to the governmental filings and other matters referred
to in Section 3.04(d), any Applicable Law; other than, in the case of clauses
(ii) and (iii), any such conflicts, violations, breaches, defaults, rights,
losses, Liens or entitlements that individually or in the aggregate could not
reasonably be expected to (A) have a Company Material Adverse Effect, or (B)
prevent or materially impede, interfere with, hinder or delay the consummation
of any of the transactions contemplated by this Agreement or the Stockholders
Agreement. A true, complete and correct list of all the Contracts (including all
amendments thereof) comprising the Credit Facility are listed in Section 3.04(c)
of the Company Disclosure Schedule.

          For purposes of this Agreement, "Credit Facility" means those
Contracts listed in Section 3.04(c) of the Company Disclosure Schedule,
collectively.

          (d) No consent, approval, authorization, waiver, permit, grant,
franchise, concession, agreement, license, exemption or order of, registration,
certificate, declaration or filing with, or report or notice to, any Person,
including any Governmental Entity (each, a "Consent"), is required by or with
respect to the Company or any of its Subsidiaries in connection with the
execution and delivery of this Agreement or the Stockholders Agreement by


                                       15







the Company, the consummation by the Company of the transactions contemplated by

(i) any filings required under any applicable competition, merger control,
antitrust or similar law; (ii) the filing with the Securities and Exchange
Commission (the "SEC") of a proxy statement relating to the approval of this
Agreement by the Company's stockholders (as amended or supplemented from time to
time, the "Proxy Statement") and such reports under the Securities Exchange Act
of 1934, as amended (the "Exchange Act"), as may be required in connection with
this Agreement, the Stockholders Agreement and the transactions contemplated
hereby and thereby; (iii) the filing of the Articles of Merger with the
Secretary of State of the State of Nevada and appropriate documents with the
relevant authorities of other states in which the Company or any of its
Subsidiaries is qualified to do business; (iv) any filings required under the

listed in Section 3.04(d) of the Company Disclosure Schedule; and (vi) such
other Consents, the failure of which other Consents to be obtained or made
individually or in the aggregate could not reasonably be expected to (A) have a
Company Material Adverse Effect, or (B) prevent or materially impede, interfere
with, hinder or delay the consummation of any of the transactions contemplated
by this Agreement or the Stockholders Agreement.

     SECTION 3.05 SEC Documents. The Company has filed with the SEC, and has
heretofore made available to Parent true and complete copies of, all reports,
schedules, forms, statements and other documents required to be filed with the
SEC by the Company since May 1, 1996 (together with all information incorporated
therein by reference, the "SEC Documents"). No Subsidiary of the Company is
required to file any report, schedule, form, statement or other document with
the SEC.

     As of their respective dates, each of the SEC Documents filed prior to June
15, 2002 (each a "Filed SEC Document") complied in all material respects with
the requirements of the Securities Act of 1933, as amended (the "Securities
Act") or the Exchange Act, as the case may be, and the rules and regulations
promulgated thereunder, and none of the Filed SEC Documents at the time they
were filed contained any untrue statement of a material fact or omitted to state
a 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 to the extent that information contained in any Filed SEC
Document has been revised or superseded by a later Filed SEC Document, none of
the SEC Documents contains any untrue statement of a material fact or omits to
state a 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.

     Each SEC Document that the Company files with the SEC on or after June 15,
2002, as of the date thereof, will comply in all material respects with the
requirements of the Securities Act or the Exchange Act, as the case may be, and
the rules and regulations promulgated thereunder, and none of such SEC Documents
will contain any untrue statement of a material fact or omit to state a 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, in the case of the Proxy Statement, no representation
is made by the Company with


                                       16







respect to statements made therein based on information supplied by Parent or
Sub in writing specifically for inclusion in the Proxy Statement.

     The financial statements (including the related notes) of the Company
included in the SEC Documents (including the Proxy Statement) and the Other
Filings complied, as of the date filed, or will comply when filed, as to form in
all material respects with applicable accounting requirements and the published
rules and regulations of the SEC with respect thereto, have been or will be
prepared in accordance with generally U.S. accepted accounting principles
("GAAP") (except, in the case of unaudited statements, as permitted by Form 10-Q
of the SEC) applied on a consistent basis during the periods involved (except as
may be indicated in the notes thereto) and fairly presented or will present in
all material respects the consolidated financial position of the Company and its
consolidated Subsidiaries as of the dates thereof and their consolidated results
of operations and cash flows for the periods then ended (subject, in the case of
unaudited statements, to normal and recurring year-end audit adjustments and the
absence of footnotes).

     SECTION 3.06 Information Supplied. None of the information supplied by the
Company for inclusion or incorporation by reference in (a) the Proxy Statement,
or (b) any other document filed or to be filed with the SEC or any other
Governmental Entity in connection with the transactions contemplated by this
Agreement (collectively, the "Other Filings") will, at the respective times
filed with the SEC or other Governmental Entity and, in addition, in the case of
the Proxy Statement, at the date it or any amendment thereof or supplement
thereto is mailed to stockholders, at the time of the Stockholders Meeting and
at the Effective Time, 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, except that, in the case of the Proxy Statement,
no representation is made by the Company with respect to statements made therein
based on information supplied by Parent or Sub in writing specifically for
inclusion in the Proxy Statement. The Proxy Statement and the Other Filings made
by the Company will comply as to form with the provisions of the Exchange Act or
other Applicable Law, as the case may be, and the rules and regulations
thereunder.

     SECTION 3.07 Absence of Certain Changes or Events. Except as set forth on
Section 3.07 of the Company Disclosure Schedule, since the date of the most
recent audited financial statements included in the Filed SEC Documents, the
Company and its Subsidiaries have conducted their respective businesses only in
the ordinary course consistent with past practice, and there has not been:

          (a) any Company Material Adverse Effect or any state of facts, change,
development, effect or occurrence that could reasonably be expected to result in
a Company Material Adverse Effect;

          (b) any declaration, setting aside or payment of any dividend on, or
other distribution (whether in cash, stock or property) in respect of, any of

capital stock or other securities;


                                       17







          (c) any split, reverse split, combination or reclassification of any
of the Company's or any of its Subsidiaries' capital stock or any issuance or
the authorization of any issuance of any other securities in respect of, in lieu

Company or any of its Subsidiaries;

          (d) (i) any granting by the Company or any of its Subsidiaries of any
increase in compensation or benefits, except for normal increases of cash
compensation prior to the date of this Agreement in the ordinary course of
business consistent (in amount and kind) with past practice, (ii) any payment by
the Company or any of its Subsidiaries of any bonus, except for bonuses made

Company or any of its Subsidiaries to any current or former director, officer,
employee or consultant of any increase in severance or termination pay, or (iv)

Intellectual Property. To the Company's or any of its Subsidiaries' knowledge,
no threats or allegations have been made, nor notice of any kind given, by the

Benefit Plan that is a Pension Plan, or any material change in the manner in
which contributions to any such Pension Plan are made or the basis on which such
contributions are determined.

SECTION 3.14 Employee Benefits Matters.

          (a) Section 3.14(a) of the Company Disclosure Schedule contains a list
of all Benefit Plans and all material Benefit Agreements, including each
"employee welfare benefit plan" (as defined in Section 3(1) of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA")) and "employee
pension benefit plan" (as defined in Section 3(2) of ERISA) (a "Pension Plan").
The Company has provided to Parent true, complete and correct copies of (i) each
Benefit Plan and each material Benefit Agreement (or, in the case of any
unwritten Benefit Plans or Benefit Agreements, descriptions thereof), (ii) the
two most recent annual reports required to be filed with respect to each Benefit
Plan (including reports filed on Form 5500), (iii) the most recent summary plan
description prepared for each Benefit Plan, (iv) each trust agreement and group
annuity contract relating to any Benefit Plan and (v) the most recent
determination or qualification letter issued by any Governmental Entity for each
Benefit Plan intended to qualify for favorable tax treatment. Each Benefit Plan
has been administered in accordance with its terms. The Company and its
Subsidiaries have caused the Benefit Plans and the administration thereof to be
in compliance in all material respects with all applicable provisions of ERISA,
the Code and all other Applicable Laws. Except as set forth in Section 3.14(a)
of the Company Disclosure Schedule, all Pension Plans intended to be
tax-qualified have been the subject of determination letters from the Internal
Revenue Service ("IRS") to the effect that such Pension Plans are qualified and
exempt from United States Federal income taxes under Sections 401(a) and 501(a),
respectively, of the Code or have remaining a period of time under applicable
Treasury regulations or IRS pronouncements in which to apply for such a letter
and make any amendments necessary to obtain such a favorable determination as to
the qualified status of each such Pension Plan; no such determination letter has
been revoked (or, to the knowledge of the Company or any of its Subsidiaries,
has revocation been threatened or otherwise communicated or considered by the
IRS); no event occurred relating to any such Pension Plan that would adversely
affect the qualification of such Pension

maintained, contributed to or been obligated to maintain or contribute to, or
has any actual or contingent liability under, any Benefit Plan that is subject
to Title IV of ERISA, including a multiemployer plan under Section 3(37) of
ERISA.

          (c) With respect to any Benefit Plan that is an employee welfare
benefit plan (each, a "Welfare Plan"), there are no understandings, agreements
or undertakings, written or oral, or summary plan description that would prevent
any such plan (including any such plan covering retirees or other former
employees) from being amended or terminated without material liability to the
Company or any of its Subsidiaries on or at any time after the Effective Time.
No Welfare Plan provides benefits after termination of employment except where
the cost thereof is borne entirely by the former employee (or his eligible
dependents or beneficiaries) or as required by Section 4980B(f) of the Code.

          (d) Except as set forth in Section 3.14(d) of the Company Disclosure
Schedule, no current or former director, officer, employee or independent
contractor of the Company or any of its Subsidiaries will be entitled to any
additional compensation or benefits or any acceleration of the time of payment
or vesting of any compensation or benefits under any Benefit Plan or Benefit
Agreement as a result of the transactions contemplated by this Agreement or the
Stockholders Agreement or any benefits under any Benefit Plan or Benefit
Agreement the value of which will be calculated on the basis of any of the
transactions contemplated by this Agreement or the Stockholders Agreement.

          (e) The deduction of any amount payable pursuant to the terms of the
Benefit Plans, Benefit Agreements or any other employment contracts or
arrangements will not be subject to disallowance under Section 162(m) of the
Code.

          (f) The Company has received no notice of and, to the knowledge of the
Company or any of its Subsidiaries there are no, pending investigations by any
Governmental Entity with respect to, or pending termination proceedings or other
claims (except claims for benefits payable in the normal operation of the
Benefit Plans), suits or proceedings against or involving any Benefit Plan or
asserting any rights or claims to benefits under, any Benefit Plan that could
give rise to any material liability, and, to the knowledge of the Company or any
of its Subsidiaries, there are not any facts that individually or in the
aggregate have had or could reasonably be expected to have a Company Material
Adverse Effect.

          (g) All contributions, premiums and benefit payments under or in
connection with the Benefit Plans that are required to have been made by the
Company or any of its Subsidiaries as of the date of this Agreement in
accordance with the terms of the Benefit Plans have been timely made or have
been reflected on the most recent consolidated balance sheet filed in or
incorporated by reference into the Filed SEC Documents.

          (h) The Company and its Subsidiaries do not have any material
liability or obligations, including under or on account of a Benefit Plan or
Benefit Agreement, arising out of


                                       29

Subsidiaries and treating such persons as consultants or independent contractors

conducted and ownership of the assets of each of the Company and its
Subsidiaries. Except as set forth in Section 3.15 of the Company Disclosure
Schedule, all such Permits and other Consents have been duly obtained and are in
full force and effect, and neither the Company nor any of its Subsidiaries is in
violation of or default under any such Permits and other Consents held by it. No
such Permit or other Consent will be revoked, terminated prior to its normal
expiration date or not renewed solely as a result of the consummation of the
transactions contemplated by this Agreement or the Stockholders Agreement.

     SECTION 3.16 Leased Real Property.

          (a) Neither the Company nor any of its Subsidiaries owns any real
property. Section 3.16(a) of the Company Disclosure Schedule lists all real
property leased or subleased to the Company or any of its Subsidiaries as of the

Company has made available to Parent true, correct and complete copies of the
leases and subleases (as amended to date) and other agreements for occupancy,
including all amendments, extensions and other modifications thereto as of the
date of this Agreement with respect to each Leased Real Property (each, a "Real
Property Lease" and, collectively, the "Real Property Leases").

          (b) With respect to each Real Property Lease, in all material
respects:

               (i) such Real Property Lease is a legal, valid and binding
obligation of the Company or its applicable Subsidiary, and is in full force and
effect;

               (ii) neither the Company or its applicable Subsidiary, nor, to
the Company's or any of its Subsidiaries' knowledge, any other party to such
Real Property Lease is in breach or default, and, to the Company's or any of its
Subsidiaries' knowledge, no event has occurred which, with notice or lapse of
time, would constitute a breach or default or permit termination, modification
or acceleration thereunder; and

               (iii) to the Company's or any of its Subsidiaries' knowledge,
there are no disputes, oral agreements or forbearance programs in effect as to
the Real Property Leases.

          (c) The Leased Real Property is sufficient for the continued conduct
of the respective businesses of the Company and its Subsidiaries in
substantially the same manner as such businesses are currently conducted.


                                       30







          (d) The Real Property Leases cover all of the Leased Real Property
currently utilized by the Company or any of its Subsidiaries; the property
covered by such Real Property Leases may legally be used for such operations
conducted thereon and all necessary access from public roads and all required
utilities are legally and validly available to the property; the improvements on
the properties or their use do not violate any existing covenants, restrictions
or easements nor encroach any adjacent property not owned by the landlords under
such Real Property Leases; the improvements on the properties are in

the future have) commercially reasonable non-disturbance assurances upon all of
the terms and conditions of the Real Property Leases from all holders of
mortgages, deeds of trust and other superior Liens and from all lessors of
underlying or ground leases. No repairs or replacements of any portion of the
property covered by the Real Property Leases are required on the part of the
Company or any of its Subsidiaries to comply with Applicable Law or to maintain
good order and repair, which are beyond normal routine maintenance.

any of its Subsidiaries' knowledge, there has not been threatened, any material
strikes, labor grievances, claims of unfair labor practices or other collective
bargaining disputes or other similar labor activity with respect to any
employees of the Company or any of its Subsidiaries. Neither the Company nor any

Takeover Proposal, or (ii) enter into, continue or otherwise participate in any
discussions or negotiations regarding, or furnish to any person any information
with respect to, or otherwise cooperate in any way with,


                                       43







any Takeover Proposal; provided, however, that at any time prior to obtaining
the Stockholder Approval, the Board of Directors of the Company may, in response
to a bona fide written Takeover Proposal that such Board of Directors reasonably
determines in good faith by resolution duly adopted constitutes a Superior
Proposal, and which Takeover Proposal was unsolicited and did not otherwise
result from a breach of this Agreement (including this Section 5.02), and
subject to compliance with Sections 5.02(b) and 5.02(c), (A) furnish information
with respect to the Company and its Subsidiaries to the person making such
Takeover Proposal (and its representatives) pursuant to a confidentiality
agreement having terms that are at least as favorable to the Company as the
terms contained in the Confidentiality Agreement, provided that all such
information is provided on a prior basis to Parent, and (B) participate in
discussions or negotiations with the person making such Takeover Proposal (and
its representatives) regarding such Takeover Proposal, but in each case only to
the extent the Board of Directors of the Company determines in good faith, after
consultation with outside counsel, by resolution duly adopted, that the failure
to take such action would constitute a breach of the fiduciary duties of the
Board of Directors of the Company under Applicable Law. Without limiting the
foregoing, it is understood that any violation of the restrictions set forth in
this Section 5.02(a) by any director, officer or employee of the Company or any
of its Subsidiaries or any investment banker, attorney, accountant or other
advisor or representative of the Company or any of its Subsidiaries shall be
deemed to be a breach of this Section 5.02(a) by the Company.

          The term "Takeover Proposal" means any inquiry, proposal or offer from
any person (other than by Parent or Sub) relating to any direct or indirect
acquisition, in one transaction or a series of transactions, including any
merger, consolidation, tender offer, exchange offer, stock acquisition, asset
acquisition, binding share exchange, business combination, recapitalization,
liquidation, dissolution, joint venture or similar transaction, of (1) assets or
businesses that constitute or represent 15% or more of the total revenue,
operating income, EBITDA or assets of the Company and its Subsidiaries, taken as
a whole, or (2) 15% or more of the outstanding shares of Company Common Stock,
or 15% or more of the outstanding shares of capital stock of, or other equity or
voting interests in, any of the Company's Subsidiaries directly or indirectly
holding, individually or taken together, the assets or businesses referred to in
clause (1) above, in each case other than the transactions contemplated by this
Agreement and the Stockholders Agreement.

          The term "Superior Proposal" means any bona fide binding written offer
not solicited, initiated, facilitated or encouraged by or on behalf of the
Company or any of its Subsidiaries made by a third party that if consummated
would result in such third party (or in the case of a direct merger between such
third party and the Company, the stockholders of such third party) acquiring,
directly or indirectly, more than 50% of the voting power of the Company Common
Stock or all or substantially all the assets of the Company and its
Subsidiaries, taken as a whole, for consideration consisting of cash and/or
securities that the Board of Directors of the Company determines in its good
faith judgment by resolution duly adopted (after consultation with a financial
advisor of nationally recognized reputation) (x) to have a higher value than the
consideration to be received by the Company's stockholders in connection with
the Merger, taking into account, among other things, any changes to the terms of
this Agreement proposed by Parent in response to such Superior Proposal or
otherwise, and (y) is reasonably capable of being consummated.


                                       44







          (b) Neither the Board of Directors of the Company nor any committee
thereof shall: (i) withdraw (or modify in a manner adverse to Parent or Sub) or
propose publicly to withdraw (or modify in a manner adverse to Parent or Sub)
the recommendation or declaration of advisability by such Board of Directors or
any such committee of this Agreement or the Merger, or resolve or agree to take
any such action (any such action or any such resolution or agreement to take
such action being referred to herein as an "Adverse Recommendation Change"),
unless the Board of Directors of the Company (A) receives a Takeover Proposal
that such Board of Directors reasonably determines in good faith by resolution
duly adopted constitutes a Superior Proposal, and which Takeover Proposal was
unsolicited and did not otherwise result from a breach of this Agreement
(including this Section 5.02), (B) reasonably determines in good faith, after
consultation with outside counsel, by resolution duly adopted, that the failure
to make an Adverse Recommendation Change in connection with such Superior
Proposal would constitute a breach of its fiduciary duties under Applicable Law,
and (C) gives Parent five business days' prior written notice of its intention
to take any such action (it being understood and agreed that no such permitted
Adverse Recommendation Change shall change the approval of the Board of
Directors of the Company for purposes of causing any state takeover statute or
other state law to be inapplicable to the transactions contemplated by this
Agreement and the Stockholder Agreement (including the Merger), or change the
obligation of the Company to present the Merger for approval at a duly called
Stockholders Meeting on the earliest practicable date determined in consultation
with Parent); (ii) recommend, adopt or approve, or propose publicly to
recommend, adopt or approve, any Takeover Proposal, or resolve or agree to take
any such action; or (iii) cause or permit the Company or any of its Subsidiaries
to enter into any letter of intent, memorandum of understanding, agreement in
principle, acquisition agreement, merger agreement, option agreement, joint
venture agreement, partnership agreement or other agreement (each, an
"Acquisition Agreement") constituting or related to, or which is intended to or
is reasonably likely to lead to, any Takeover Proposal (other than a
confidentiality agreement referred to in Section 5.02(a)) or resolve or agree to
take any such action.

          (c) In addition to the obligations of the Company set forth in
Sections 5.02(a) and 5.02(b), the Company promptly shall (but in any event
within one calendar day) advise Parent in writing (i) of any direct or indirect
request for information that the Company reasonably believes could lead to or
contemplates a Takeover Proposal or of any Takeover Proposal, or any inquiry the
Company reasonably believes could lead to any Takeover Proposal, the specific
terms and conditions of such request, Takeover Proposal or inquiry (including
any subsequent material amendment or modification to such terms and conditions)
and the identity of the person making any such request, Takeover Proposal or
inquiry, and (ii) if the Board of Directors of the Company shall make any
determination as to any Takeover Proposal as contemplated by the proviso to the
first sentence of Section 5.02(a). The Company shall keep Parent informed on a
current basis of the status and specific details (including material amendments
or proposed amendments) of any such request, Takeover Proposal or inquiry.

          (d) Nothing contained in this Section 5.02 or elsewhere in this
Agreement shall prohibit the Company from (i) taking and disclosing to its
stockholders a position contemplated by Rule 14e-2(a) promulgated under the
Exchange Act, or (ii) making any disclosure to the Company's stockholders if the
Board of Directors of the Company determines in good faith, after consultation
with outside counsel, by resolution duly adopted, that the failure so to
disclose would be inconsistent with Applicable Law; provided, however, that in
no event


                                       45







shall the Company or its Board of Directors or any committee thereof take, agree
or resolve to take any action prohibited by Section 5.02(b).

          (e) If prior to the Stockholder Approval, the Board of Directors of
the Company receives a Takeover Proposal that such Board of Directors reasonably
determines in good faith by resolution duly adopted constitutes a Superior
Proposal and that was not solicited, initiated, facilitated or encouraged after
the date of this Agreement in violation of this Agreement, then the Board of
Directors of the Company may (subject to this and the following sentences of
this Section 5.02(e)) terminate this Agreement pursuant to Section 8.01(f) and
enter into a definitive acquisition agreement with respect to such Takeover
Proposal; provided, however, that, prior to any such termination, (i) the
Company has provided Parent written notice that it intends to terminate this
Agreement pursuant to Section 8.01(f), identifying the Takeover Proposal then so
determined to be a Superior Proposal and the parties thereto and all of the
material terms thereof, (ii) the Company has delivered a copy of the definitive
acquisition agreement for such Takeover Proposal in the form to be entered into,
and (iii) at least five days after the Company has provided the notice referred
to in clause (i) above and at least 48 hours after the Company has made the
delivery required in clause (ii) above (provided such Board of Directors
reasonably determines in good faith by resolution duly adopted that such
Takeover Proposal continues to be a Superior Proposal), the Company delivers to
Parent (A) a written notice of termination of this Agreement pursuant to Section
8.01(f), and (B) the Termination Fee (as provided in Section 8.03(b)). For
purposes of this Section 5.02(e), the term "Takeover Proposal" shall have the
meaning set forth in Section 8.03(b)(i)(B).

     SECTION 5.03 Indebtedness. The Company will take all actions necessary to
ensure that the condition precedent set forth in Section 7.02 (f) will be
satisfied. In addition, during the period commencing on the Balance Sheet Date
and ending on the Closing Date, the Company shall not (and the Company shall
cause all of its Subsidiaries to not) incur any Indebtedness (other than for
interest accruing during such period under and pursuant to the terms of those
instruments governing the Indebtedness of the Company or any of its Subsidiaries
existing on the Balance Sheet Date).

                                   ARTICLE VI
                              ADDITIONAL AGREEMENTS

     SECTION 6.01 Preparation of the Proxy Statement; Stockholders Meeting.

          (a) As promptly as reasonably practicable following the date of this
Agreement, the Company shall prepare and file with the SEC the Proxy Statement
and the Company shall use its reasonable best efforts to respond as promptly as
practicable to any comments of the SEC with respect thereto and to cause the
Proxy Statement to be mailed to the Company's stockholders as promptly as
reasonably practicable following the date of this Agreement. The Company shall
promptly notify Parent upon the receipt of any comments from the SEC or its
staff or any request from the SEC or its staff for amendments or supplements to
the Proxy Statement and shall provide Parent with copies of all correspondence
between the Company and its representatives, on the one hand, and the SEC and
its staff, on the other hand. Notwithstanding anything to the contrary stated
above, prior to filing or mailing the Proxy Statement (or any amendment thereof
or supplement thereto) or responding to any comments of


                                       46







the SEC with respect thereto, the Company shall (i) provide Parent an
opportunity to review, comment on and approve such document or response, (ii)
include in such document or response all comments reasonably proposed by Parent
and (iii) not file or mail such document or respond to the SEC prior to
receiving Parent's approval.

          (b) The Company shall, as promptly as reasonably practicable following
the date of this Agreement, establish a record date (which will be as promptly
as reasonably practicable following the date of this Agreement) for, duly call,
give notice of, convene and hold a meeting of its stockholders (the
"Stockholders Meeting") for the purpose of obtaining the Stockholder Approval,
regardless of whether the Board of Directors of the Company determines at any
time that this Agreement is no longer advisable and recommends that the
stockholders of the Company reject it or any other Adverse Recommendation Change
has occurred. The Company shall cause the Stockholders Meeting to be held as
promptly as reasonably practicable after the date of this Agreement, but in any
event shall be on the 9th business day of a month. Subject to Section
5.02(b)(i), the Company shall, through its Board of Directors, recommend to its
stockholders that they adopt this Agreement, and shall include such
recommendation in the Proxy Statement. Without limiting the generality of the
foregoing, the Company agrees that its obligations pursuant to this Section
6.01(b) shall not be affected by the commencement, public proposal, public
disclosure or communication to the Company or any other person of any Takeover
Proposal.

     SECTION 6.02 Access to Information; Confidentiality. The Company shall, and
shall cause each of its Subsidiaries to, afford to Parent, and to Parent's
officers, employees, investment bankers, attorneys, accountants and other
advisors and representatives, full access during normal business hours during
the period prior to the Effective Time or the termination of this Agreement
pursuant to Article VIII to all their respective properties, books, contracts,
commitments, directors, officers, employees, attorneys, accountants, auditors
(and, to the extent within the Company's control, former auditors), other
advisors and representatives and records and, during such period, the Company
shall, and shall cause each of its Subsidiaries to, make available to Parent (a)
a copy of each report, schedule, form, statement and other document filed or
received by it during such period pursuant to the requirements of Applicable
Law, and (b) all other information concerning its business, properties and
personnel as Parent may reasonably request (including the work papers of
independent public accountants). Except as required by Applicable Law, Parent
will hold, and will direct its officers, employees, investment bankers,
attorneys, accountants and other advisors and representatives to hold, any and
all information received from the Company, directly or indirectly, in confidence
in accordance with the Confidentiality Agreement, dated October 6, 2000, between
Parent and Quarterdeck Investment Partners, Inc. (as it may be amended from time
to time, the "Confidentiality Agreement").

     SECTION 6.03 Reasonable Best Efforts; Notification.

          (a) Upon the terms and subject to the conditions set forth in this
Agreement, each of the parties agrees to use its reasonable best efforts to
take, or cause to be taken, all actions that are necessary, proper or advisable
to consummate and make effective the Merger and the other transactions
contemplated by this Agreement and the Stockholders Agreement, including using
its reasonable best efforts to accomplish the following: (i) the taking of all
acts necessary to cause the conditions precedent set forth in Article VII to be
satisfied; (ii) the


                                       47







obtaining of all necessary actions, nonactions and Consents from Governmental
Entities and the making of all necessary registrations, declarations and filings
(including registrations, declarations and filings with Governmental Entities,
if any); (iii) the taking of all steps as may be necessary to avoid any suit,
claim, action, investigation or proceeding by any Governmental Entity; (iv) the
obtaining of all Consents from third parties; and (v) the defending of any suit,
claim, action, investigation or proceeding, whether judicial or administrative,
challenging or seeking to restrain or prohibit the consummation of the
transactions contemplated by this Agreement, including the Merger. In connection
with and without limiting the foregoing, the Company and its Board of Directors
shall, if any state takeover statute or similar statute or regulation is or
becomes applicable to this Agreement, the Stockholders Agreement, the Merger or
any of the other transactions contemplated hereby or thereby, use their
reasonable best efforts to ensure that the Merger and the other transactions
contemplated hereby or thereby may be consummated as promptly as practicable on
the terms contemplated by this Agreement and otherwise to minimize the effect of
such statute or regulation on this Agreement, the Stockholders Agreement, the
Merger and the other transactions contemplated hereby or thereby. The Company
and Parent will provide such assistance, information and cooperation to each
other as is reasonably required to obtain any actions, nonactions and Consents
referred to above and, in connection therewith, will notify the other party
promptly following the receipt of any comments from any Governmental Entity and
of any request by any Governmental Entity for amendments, supplements or
additional information in respect of any registration, declaration or filing
with such Governmental Entity and will supply the other party with copies of all
correspondence between such person or any of its representatives, on the one
hand, and any Governmental Entity, on the other hand.

          (b) Notwithstanding Section 6.03(a) or any other provision of this
Agreement to the contrary, in no event shall any party hereto be obligated to:
(i) agree to, or proffer to, divest or hold separate, or enter into any
licensing or similar arrangement with respect to, any assets (whether tangible
or intangible) or any portion of any business of Parent, the Company or any of
their respective Subsidiaries; or (ii) litigate any suit, claim, action,
investigation or proceeding, whether judicial or administrative, (A) seeking to
prohibit or limit the ownership or operation by the Company, Parent or any of
their respective Affiliates of a material portion of the business or assets of
the Company and its Subsidiaries, taken as a whole, or Parent and its
Subsidiaries, taken as a whole, or to require any such person to dispose of or
hold separate any material portion of the business or assets of the Company and
its Subsidiaries, taken as a whole, or Parent and its Subsidiaries, taken as a
whole, as a result of the Merger, or (B) seeking to prohibit Parent or any of
its Affiliates from effectively controlling a material portion of the business
or operations of the Company or its Subsidiaries.

          (c) Without limiting the generality of the foregoing, the Company
shall give Parent the opportunity to participate in the defense of any
litigation against the Company and/or its directors relating to the transactions
contemplated by this Agreement.

     SECTION 6.04 Indemnification.

          (a) Parent agrees that all rights to indemnification now existing for
actions occurring prior to the Effective Time in favor of any individual who at
or prior to the Effective Time was a director, officer, employee or agent of the
Company or any of its Subsidiaries (the


                                       48







"Indemnified Parties") as provided in their respective articles of incorporation
or bylaws (or similar organizational documents), shall survive the Merger and
shall continue in full force and effect for a period of not less than six years
from the Effective Time unless otherwise required by law; provided, however,
that if any claim or claims are asserted or made within such six-year period,
all rights to indemnification in respect of any such claim or claims shall
continue until final disposition of any and all such claims.

          (b) Parent agrees that the Company and, from and after the Effective
Time, the Surviving Corporation shall cause to be maintained in effect for not
less than three years (except as provided in the last proviso of this Section
6.04(b)) from the Effective Time the current policies of the directors' and
officers' liability insurance maintained by the Company; provided, however that
the Surviving Corporation may substitute therefor policies of at least the same
coverage containing terms and conditions which are not significantly less
advantageous to the beneficiaries of the current policies and provided that such
substitution shall not result in any gaps or lapses in coverage with respect to
matters occurring prior to the Effective Time; provided further, however that
the Surviving Corporation shall not be required to pay an annual premium in
excess of 150% of the last annual premium paid by the Company prior to the date
hereof (which the Company represents to be $42,000 for the 12-month period
ending March 31, 2003) and if the Surviving Corporation is unable to obtain the
insurance required by this Section 6.04(b) it shall obtain as much comparable
insurance as possible for an annual premium equal to such maximum amount.

     SECTION 6.05 Employee Matters.

          (a) For a period of at least 12 months following the Effective Date,
Parent shall provide (or shall cause the Surviving Corporation or its
Subsidiaries to provide) each employee who is employed by the Company or any of
its Subsidiaries as of the Closing Date (a "Continuing Employee") with
compensation and employee benefits (other than stock or other equity or
equity-linked based plans) which are substantially comparable in the aggregate
to those provided by the Company or such Subsidiary as of the date hereof. The
Company acknowledges that following the Effective Date all employee benefits
will be provided to employees of the Surviving Corporation under plans sponsored
by Parent or an Affiliate of Parent. Parent will use its reasonable best efforts
(i) to waive or have the Surviving Corporation waive any waiting period or
limitations regarding pre-existing conditions with respect to Continuing
Employees and their beneficiaries under any group health or other benefit plan
maintained by Parent for the benefit of any Continuing Employees after the
Effective Date, (ii) to credit any covered expenses incurred by any employee
under the Company's group health plan prior to the Effective Date towards any
deductibles, limits or out-of-pocket maximums under any group health plan
maintained by Parent for the benefit of any Continuing Employees after the
Effective Date, (iii) to credit the service of each Continuing Employee with the
Company or any of its Subsidiaries prior to the Effective Date for the purposes
of determining such Continuing Employee's years of service under plans
maintained by Parent for the benefit of any Continuing Employee after the
Effective Date, (iv) provide severance benefits to Continuing Employees
terminated without cause within 12 months of the Effective Date that are
substantially comparable to the severance that would have been provided by the
Company under the Company's severance plans in effect on the date hereof, and
(v) provide continuation health care coverage to all Continuing Employees and
their qualified beneficiaries who incur a qualifying event on and after the


                                       49







Effective Date in accordance with the continuation health care coverage
requirements of the Consolidated Omnibus Budget Reconciliation Act of 1985, as
amended. In addition, Parent shall assume responsibility for the cafeteria plan
which is maintained under Section 125 of the Code for the benefit of the
Continuing Employees of the Company, and the Company shall provide to Parent
prior to the Effective Date a list of those Continuing Employees participating
in the cafeteria plan, together with a list of their elections made prior to the
Effective Date, and any balances in their respective accounts as of the
Effective Date.

          (b) The Company will cause the Company's Retirement Savings 401(K)
Plan (the "Existing 401(K) Plan") to be amended to provide that the transactions
contemplated by this Agreement shall be a distributable event under the Existing
401(K) Plan. Parent will amend its 401(K) Plan to accept rollover contributions
and direct rollovers from the Continuing Employees, including any outstanding
loans held under the Existing 401(K) Plan.

     SECTION 6.06 Public Announcements. Parent and Sub, on the one hand, and the
Company, on the other hand, will, to the extent reasonably practicable, consult
with each other before issuing, and give each other a reasonable opportunity to
review and comment upon, any press release or other public statements with
respect to this Agreement, the Stockholders Agreement, the Merger and the other
transactions contemplated hereby and thereby, and shall not issue any such press
release or make any such public statement prior to such consultation, except as
may be required by Applicable Law, court process or by obligations pursuant to
any listing agreement with any national securities exchange or national
securities quotation system. The parties agree that the initial press release to
be issued with respect to the transactions contemplated by this Agreement and
the Stockholders Agreement shall be in the form heretofore agreed to by the
parties.

     SECTION 6.07 Additional Reports. The Company timely shall file all SEC
Documents and Other Filings required to be filed by it with the SEC or other
Governmental Entities on or after the date of this Agreement, and promptly shall
furnish to Parent copies of such SEC Documents and Other Filings which it so
files.

     SECTION 6.08 Pre-Closing Date Balance Sheet. The Company shall prepare and
deliver to Parent on or prior to the sixth business day of the month during
which the Closing will occur an unaudited consolidated balance sheet of the
Company and its Subsidiaries (the "Pre-Closing Date Balance Sheet") at and as of
the last day of the most recently completed calendar month ending immediately
preceding the Closing Date (the "Balance Sheet Date"), to be prepared as set
forth in this Section 6.08 using actual data through the Balance Sheet Date. The
Company shall provide to Parent any information and back-up materials reasonably
requested by Parent with respect thereto. The Pre-Closing Date Balance Sheet
shall be prepared applying GAAP on a basis consistent with the audited
consolidated balance sheet of the Company and its Subsidiaries at and as of
March 31, 2002 included in the SEC Documents (the "March 31, 2002 Balance
Sheet") through full application of the accounting methods, treatments, policies
and procedures used by the Company in preparing the March 31, 2002 Balance
Sheet, shall fairly present in all material respects the consolidated financial
position of the Company and its Subsidiaries as of the date thereof, and shall
contain changes in contract estimates at completion ("EACs") and estimates to
complete ("ETCs") determined on a basis consistent with the method


                                       50







used for the determination of such amounts in the March 31, 2002 Balance Sheet,
except as modified or set forth in subparagraphs (i) through (vii) below in this
Section 6.08:

               (i) Adjustment of Reserves and Valuation Accounts. The amount of
any reserve or valuation accounts shall be determined by applying methods,
practices, assumptions, policies, factors and underlying data consistent with
those used in determining the reserves or valuation accounts included in the
March 31, 2002 Balance Sheet, and there shall be no increases or decreases made
to any reserves or valuation accounts in the Pre-Closing Date Balance Sheet
(including contract reserves, purchase accounting reserves, deferred tax asset
valuation accounts, allowances for bad debts, inventory reserves of any kind,
warranty reserves, income tax reserves and other reserves), except to the extent
that such changes are required by documented and substantiated changes in facts
and events occurring after March 31, 2002 and on or before the Balance Sheet
Date and are not solely the result of changes in management estimates. It is
further understood that there shall be no increase in the Balance Sheet Date Net
Worth as a result of any reversal, reduction or other usage of reserves included
in the March 31, 2002 Balance Sheet unless such reversal, reduction or usage was
caused by facts or events that occurred after March 31, 2002, and on or before
the Balance Sheet Date; provided, however, that if such facts causing such
reversal or reduction existed and applied to, and were known or should have been
known as of March 31, 2002, the reversals or reductions also shall be made to
the March 31, 2002 Balance Sheet for purposes of increasing the Target Net
Worth.

               (ii) Contract Estimates at Completion. There shall be no changes
to the contract EACs from those contract EACs used in the preparation of the
March 31, 2002 Balance Sheet, except to the extent that such changes are
required by documented and substantiated changes in facts and events occurring
after March 31, 2002 and on or before the Balance Sheet Date and are not solely
the result of changes in management estimates. Notwithstanding subparagraph (vi)
below in this Section 6.08, it is further understood that if the contract EACs
used in preparation of the March 31, 2002 Balance Sheet are discovered to have
been incorrect because of estimating errors, of any kind, including because
certain costs were omitted from or included in those contract EACs, for whatever
reason(s), including misallocation of direct or indirect costs to such contract
EACs, such errors (including costs that were omitted from or included in the
contract EACs) in the preparation of the March 31, 2002 Balance Sheet shall be
corrected in the contract EACs used in the preparation of the Pre-Closing Date
Balance Sheet.

               (iii) Loss Contracts. There shall be no changes made to the
provisions for loss contracts from those used in the preparation of the March
31, 2002 Balance Sheet, except to the extent that such changes are required by
documented and substantiated changes in facts and events occurring after March
31, 2002 and on or before the Balance Sheet Date and are not solely the result
of changes in management estimates. It is further understood that loss contract
reserves for contract bids and proposals and unexercised contract options of the
Company that were in a loss position and outstanding at March 31, 2002 and which
are awarded or exercised during the period between March 31, 2002 through and
including the Balance Sheet Date shall be accrued and included in the
Pre-Closing Date Balance Sheet.

               (iv) Adjustment of Liability and Accrual Accounts. The amount of
all liability and accrual accounts, shall be determined by applying methods,
practices, assumptions,


                                       51







policies, factors and underlying data consistent with those used in determining
such accounts included in the March 31, 2002 Balance Sheet, and there shall be
no changes made to any accounts, except to the extent that such changes are
required by documented and substantiated changes in facts and events occurring
after March 31, 2002 and on or before the Balance Sheet Date and are not solely
the result of changes in management estimates. It is further understood that
there shall be no increase in the Balance Sheet Date Net Worth as a result of
reversals or reductions of liability and accrual accounts, unless such reversal
or reduction was caused by facts or events that occur after March 31, 2002 and
on or before the Balance Sheet Date; provided, however, that if such facts
causing such reversal or reduction existed and applied to, and were known or
should have been known as of March 31, 2002, the reversals or reductions also
shall be made to the March 31, 2002 Balance Sheet for purposes of increasing the
Target Net Worth.

               (v) Consistent Application of Accounting Policies, Methods and
Practices. The accounting policies, methods and practices and their related
applications used by the Company to prepare the Pre-Closing Date Balance Sheet
shall be consistent with those underlying the March 31, 2002 Balance Sheet. Use
of different or alternative accounting policies and methods that are otherwise
in accordance with GAAP is not permitted because such use violates this
consistency requirement. Specifically, the Company shall be precluded from
waiving or allowing "inconsistency" adjustments recorded by the Company during
the preparation of the Pre-Closing Date Balance Sheet on the basis of
"materiality" as the term is used and understood by the Company and Ernst &
Young LLP.

               (vi) Accounting for Certain Assumed Liabilities. The Pre-Closing
Date Balance Sheet shall include liabilities required by GAAP for all assumed
obligations of the Company that accrue from March 31, 2002 to the Balance Sheet
Date including those that accrue because of the passage of time or the
achievement or reasonably expected achievement of a performance measurement,
even if such liabilities were not included in the March 31, 2002 Balance Sheet.
Examples of these types of liabilities include, but are not limited to
warranties, customer and vendor claims against the Company, litigation, taxes,
management incentive bonuses, profit sharing plans, employer matching
contributions for sponsored savings plans, and compensated absences (vacation
time, sick pay, etc.). Such liabilities shall be accrued on a pro rata basis as
of the Balance Sheet Date even if the Company's accounting policies, including
those accounting policies underlying the March 31, 2002 Balance Sheet, only
required that such liabilities be accrued at the end of the Company's fiscal
year.

               (vii) Goodwill and Other Intangible Assets. Notwithstanding GAAP
or the Company's accounting policies, there shall be no increases or decreases
to goodwill and other intangible assets from those used in preparation of the
March 31, 2002 Balance Sheet and included in the Target Net Worth.

          The Company shall provide Parent such access to the books and records
of the Company and its Subsidiaries and appropriate employees of the Company as
may reasonably be required for the review of the Pre-Closing Date Balance Sheet.

any time after March 31, 2002, if any.

similar agreements (including interest-rate, exchange-rate, commodity and
equity-linked agreements), (E) any obligations of such Person in respect of
off-balance-sheet agreements or transactions that are in the nature of, or in
substitution of, financings, and (F) any indebtedness or other obligations of

such Person is liable, contingently or otherwise, including liable by way of
agreement to purchase products or securities, to provide funds for payment, to
maintain working capital or other balance sheet conditions or otherwise to
assure a creditor against loss; provided, however, that, with respect to the
Company and its Subsidiaries, the term "Indebtedness" shall not include the
aggregate outstanding principal amount in respect of the Convertible Notes (it
being understood and agreed, however, that the term "Indebtedness" shall include
any accrued and unpaid interest on the Convertible Notes).

               (iv) "Target Net Worth" shall mean $12,007,593 (i.e., the excess
of the consolidated assets set forth on the March 31, 2002 Balance Sheet over
the consolidated liabilities (excluding for purposes of this calculation the
Indebtedness of the Company and its Subsidiaries) set forth on the March 31,
2002 Balance Sheet), as such $12,007,593 amount may be increased from time to
time pursuant to, and in accordance with, the procedures set forth in Section
6.08.

          (g) No Material Adverse Effect. Since the date of the latest audited

     SECTION 8.01 Termination. This Agreement may be terminated, and the Merger
contemplated hereby may be abandoned, at any time prior to the Effective Time,
whether before or after the Stockholder Approval has been obtained:

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

          (b) by either Parent or the Company:

               (i) if the Merger shall not have been consummated within 180 days
after the date of this Agreement for any reason; provided, however, that the
right to terminate this Agreement under this Section 8.01(b)(i) shall not be
available to any party whose action or failure to act has been a principal cause
of or resulted in the failure of the Merger to occur on or before such date and
such action or failure to act constitutes a breach of this Agreement;


                                       56







               (ii) if any Legal Restraint having the effect set forth in
Section 7.01(c) shall be in effect and shall have become final and
nonappealable; or

               (iii) if the Stockholder Approval shall not have been obtained at
the Stockholders Meeting duly convened therefor or at any adjournment or
postponement thereof.

          (c) by Parent if: (i) an Adverse Recommendation Change has occurred;
or (ii) the Board of Directors of the Company or any committee thereof shall
have failed to confirm its recommendation and declaration of advisability of
this Agreement and the Merger within ten business days after a written request
by Parent that it do so;

          (d) by Parent: (i) if the Company shall have breached in any material
respect any of its representations, warranties, covenants or other agreements
contained in this Agreement, which breach or failure to perform (A) would give
rise to the failure of a condition set forth in Section 7.02(a) or 7.02(b), and
(B) has not been or is incapable of being cured by the Company within 15
calendar days after its receipt of written notice thereof from Parent; or (ii)
if any Legal Restraint having any of the effects referred to in clauses (i)
through (iv) of Section 7.02(c) shall be in effect and shall have become final
and nonappealable;

          (e) by the Company, if Parent shall have breached in any material
respect any of its representations, warranties, covenants or other agreements
contained in this Agreement, which breach or failure to perform (i) would give
rise to the failure of a condition set forth in Section 7.03(a) or 7.03(b), and
(ii) has not been or is incapable of being cured by Parent within 15 calendar
days after its receipt of written notice thereof from the Company;

          (f) by the Company, if the Board of Directors of the Company shall
have approved, and the Company shall concurrently with such termination enter
into, a definitive agreement providing for the implementation of the
transactions contemplated by a Takeover Proposal that such Board of Directors
reasonably determines in good faith by resolution duly adopted constitutes a
Superior Proposal; provided, however, that (i) such Takeover Proposal was not
solicited, initiated, facilitated or encouraged by the Company and did not
otherwise result from a breach of Section 5.02, (ii) the Board of Directors of
the Company shall have complied with all the requirements of Section 5.02
(including Section 5.02(e)) in connection with such Takeover Proposal, and (iii)
no termination pursuant to this Section 8.01(f) shall be effective unless the
Company shall simultaneously pay to Parent the Termination Fee (as provided in
Section 8.03(b)). For purposes of this Section 8.01(f), the term "Takeover
Proposal" shall have the meaning set forth in Section 8.03(b)(i)(B).

     SECTION 8.02 Effect of Termination. In the event of termination of this
Agreement by either the Company or Parent as provided in Section 8.01, this
Agreement shall forthwith become void and have no effect, without any liability
or obligation on the part of Parent, Sub or the Company, other than the
provisions of Section 3.34, Section 5.01(e), the last sentence of Section 6.02,
this Section 8.02, Section 8.03 and Article IX, which shall survive any such
termination. In addition and without limiting the foregoing, if such termination
results from a material breach by a party of any of its representations,
warranties, covenants or agreements set forth in this Agreement, then such
termination shall not affect such party's liabilities or obligations in respect
of such material breach.


                                       57







     SECTION 8.03 Fees and Expenses.

          (a) Whether or not the Merger is consummated, except as otherwise
provided herein, all costs and expenses incurred in connection with this
Agreement, the Merger and the other transactions contemplated by this Agreement
shall be paid by the party incurring such expenses.

          (b) If: (i) (A) this Agreement is terminated by either Parent or the
Company pursuant to Section 8.01(b)(iii), and (B) within 12 months of the date
of such termination, the Company or any of its Subsidiaries enters into any
Acquisition Agreement with respect to, or consummates, any Takeover Proposal
(solely for purposes of this Section 8.03(b)(i)(B), the term "Takeover Proposal"
shall have the meaning set forth in the definition of Takeover Proposal
contained in Section 5.02(a) except that all references to 15% shall be deemed
references to 40%); (ii) this Agreement is terminated by Parent pursuant to
Section 8.01(c), or (iii) this Agreement is terminated by the Company pursuant
to Section 8.01(f), then the Company shall pay Parent a fee equal to $1,100,000
(the "Termination Fee") by wire transfer of same day funds to an account
designated by Parent (x) in the case of a termination by Parent pursuant to
Section 8.01(c), within two business days after such termination, (y) in the
case of a payment as a result of any event referred to in Section 8.03(b)(i)(B),
upon the first to occur of any such events, and (z) in the case of a termination
by the Company pursuant to Section 8.01(f), simultaneously with such
termination.

          (c) If (i) this Agreement is terminated by either Parent or the
Company pursuant to Section 8.01(b)(iii), (ii) this Agreement is terminated by
the Company pursuant to Section 8.01(b)(i), (iii) this Agreement is terminated
by Parent pursuant to Section 8.01(c) or Section 8.01(d)(i), or (iv) this
Agreement is terminated by the Company pursuant to Section 8.01(f), then (in
addition to any Termination Fee to which Parent may be entitled to pursuant to
Section 8.03(b)) the Company shall reimburse Parent for all its reasonable
out-of-pocket expenses actually incurred in connection with this Agreement
(including legal fees), the Stockholders Agreement and the transactions
contemplated hereby and thereby, which amount shall be payable by wire transfer
of same day funds within three business days of written demand therefor.

          (d) The Company acknowledges that the agreements contained in Sections
8.03(b) and 8.03(c) are an integral part of the transactions contemplated by
this Agreement, and that, without these agreements, Parent would not enter into
this Agreement. Accordingly, if the Company fails promptly to pay the amounts
due pursuant to Sections 8.03(b) and 8.03(c), and, in order to obtain such
payment, Parent commences a suit that results in a judgment against the Company
for the amounts set forth in Sections 8.03(b) and 8.03(c), the Company shall pay
to Parent its reasonable costs and expenses (including attorneys' fees and
expenses) in connection with such suit and any appeal relating thereto, together
with interest on the amounts set forth in Sections 8.03(b) and 8.03(c) at the
prime rate of Citibank, N.A. in effect on the date such payment was required to
be made.

     SECTION 8.04 Amendment. This Agreement may be amended by the parties hereto
at any time, whether before or after the Stockholder Approval has been obtained;
provided, however, that, after the Stockholder Approval has been obtained, there
shall be made


                                       58







no amendment that by law requires further approval by stockholders of the
parties without the further approval of such stockholders. This Agreement may
not be amended except by an instrument in writing signed on behalf of each of
the parties hereto.

     SECTION 8.05 Extension; Waiver. At any time prior to the Effective Time,
the parties may (a) extend the time for the performance of any of the
obligations or other acts of the other parties, (b) waive any inaccuracies in
the representations and warranties contained herein or in any document delivered
pursuant hereto, or (c) waive compliance with any of the agreements or
conditions contained herein; provided, however, that, after the Stockholder
Approval has been obtained, there shall be made no waiver that by law requires
further approval by stockholders of the parties without the further approval of
such stockholders. Any agreement on the part of a party to any such extension or
waiver shall be valid only if set forth in an instrument in writing signed on
behalf of such party. The failure or delay by any party to this Agreement to
assert any of its rights under this Agreement or otherwise shall not constitute
a waiver of such rights nor shall any single or partial exercise by any party to
this Agreement of any of its rights under this Agreement preclude any other or
further exercise of such rights or any other rights under this Agreement.

                                   ARTICLE IX
                               GENERAL PROVISIONS

     SECTION 9.01 Nonsurvival of Representations and Warranties. None of the
representations and warranties in this Agreement or in any instrument delivered

hereto irrevocably and unconditionally waives (and agrees not to plead or claim)

                                        2

or any applicable state securities laws. The sale and delivery, if any, of the

     SECTION 2. Covenants of Each Stockholder. Each Stockholder, severally and
not jointly, only as to itself, covenants and agrees as follows:

     (a) At any meeting of the stockholders of the Company called to vote upon
the Merger Agreement, the Merger or any of the other transactions contemplated
by the Merger Agreement, or at any adjournment thereof, or in any other
circumstances upon which a vote, consent, adoption or other approval (including
by written consent solicitation) of such stockholders with respect to the Merger
Agreement, the Merger or any of the other transactions contemplated by the

cause to be consented to), the adoption of the Merger Agreement and the approval
of the terms thereof and of the Merger and each of the other transactions
contemplated by the Merger Agreement.

this Agreement.

     (d) During the term of this Agreement, such Stockholder shall not request
that the Company register the Transfer (book-entry or otherwise) of any

required under the Pledge Agreements, unless such Transfer is made in compliance
with this Agreement (including the provisions of Sections 2(h) and 2(i)).

          The Company shall ensure that no Transfer in violation of this
Agreement shall be made or recorded on the books of the Company and any such

such Stockholder or any of its Affiliates, or any investment banker, attorney or
other advisor or representative of such Stockholder or any of its Affiliates to,
directly or indirectly, (i) solicit, initiate or encourage, or take any other

in any way with, or assist or participate in any effort or attempt by any Person
with respect to, any Takeover Proposal (as defined in Section 5.02(a) of the
Merger Agreement) or Frustrating Transaction.

          Notwithstanding the preceding paragraph of this Section 2(e) and
notwithstanding Section 2(f), nothing in this Agreement shall limit or restrict
a Stockholder that is a director of the Company or limit or restrict a partner
or an employee or agent of a Stockholder that is a director of the Company from

the Company to the extent that such Board of Directors is engaging in activities
expressly and specifically permitted under Section 5.02 of the Merger Agreement.

     (f) (i) During the term of this Agreement, such Stockholder shall take, or
cause to be taken, all actions, and do, or cause to be done, and assist and

                                        4







parties in doing, all things necessary, proper or advisable to consummate and

not commit or agree to take any action inconsistent with the transactions
contemplated by this Agreement or the transactions contemplated by the Merger
Agreement.

          (ii) During the term of this Agreement, such Stockholder shall not,
and such Stockholder shall not permit any of its Affiliates to, or authorize or
permit any director, officer, employee, partner or agent of such Stockholder or
any of Affiliates or any investment banker, attorney or other advisor or
representative of such Stockholder or any of its Affiliates to, directly or
indirectly, issue any press release or make any other public statement with
respect to the Merger Agreement, this Agreement, the Merger or any other
transactions contemplated by the Merger Agreement or any of the transactions
contemplated by this Agreement without the prior written consent of Parent,
except as may be required by Applicable Law or as expressly contemplated by
Section 6.06 of the Merger Agreement.

     (g) Such Stockholder hereby waives any rights of appraisal in connection
with, or rights to dissent from, the Merger that such Stockholder may have.

     (h) (i) If (A) (1) the Merger Agreement is terminated (x) by either Parent
or the Company pursuant to Section 8.01(b)(iii) of the Merger Agreement, (y) by
Parent pursuant to Section 8.01(c) of the Merger Agreement, or (z) by the
Company pursuant to Section 8.01(f) of the Merger Agreement, (2) an Acquisition
Agreement with respect to any Takeover Proposal (as defined in Section
8.03(b)(i)(B) of the Merger Agreement) is entered into by the Company or any of
its Subsidiaries within 12 months after such termination of the Merger
Agreement, and (3) such Takeover Proposal (as defined in Section 8.03(b)(i)(B)
of the Merger Agreement) is consummated within 24 months of such termination, or
(B) a Parent Takeover Proposal (as defined in Section 2(h)(vi)) made by Parent
(including any amendment of the Merger Agreement) which provides for Transaction
Consideration (as defined in Section 2(h)(iii)) in excess of $2.30 (as such
amount may be adjusted from time to time for any of the events referred to in
the last sentence of Section 6, the "Deal Price") per share is consummated (any
Takeover Proposal or Parent Takeover Proposal referred to in clause (A) or (B)
above is referred to herein as a "Transaction"), then such Stockholder shall pay
to Parent an amount in cash equal to such Stockholder's Profit (as defined in
Section 2(h)(ii)); provided, however, that if all or any part of the Transaction
Consideration which such Stockholder is entitled to receive is not cash, then
such Stockholder's Profit shall be paid to Parent in each type of consideration
paid to such Stockholder and in the same proportions as the types of
consideration comprising the Transaction Consideration which such Stockholder is
entitled to receive, in each case determined at the close of business on the
date of the consummation of the Transaction, such that (1) in respect of
Transaction Consideration to be paid to such Stockholder in cash, Parent shall
be paid Profits by such Stockholder in cash in an amount equal to the aggregate
Transaction Consideration to be paid to such Stockholder in cash multiplied by a
fraction (x) the numerator of which is equal to such Stockholder's Profit and
(y) the denominator of which is equal to the aggregate Transaction Consideration
to be received by such Stockholder (such fraction, the "Profit Percentage"), (2)
in respect of Transaction Consideration to be paid to such Stockholder in the
form of securities, Parent shall be paid Profits by such Stockholder, for each
type of securities to be so paid, in the form of that number of such securities
that is equal to the total


                                        5







number of such securities to be paid to such Stockholder multiplied by the
Profit Percentage, and (3) in respect of Transaction Consideration to be paid to
such Stockholder in consideration of a type other than cash or securities,
Parent shall be paid Profits by such Stockholder in the form of such type of
consideration and in an amount equal to the aggregate fair market value of such
consideration to be paid to Stockholder, with such fair market value determined
as of the date of the consummation of the relevant transaction, multiplied by
the Profit Percentage; provided further, however, that all such determinations
shall be made as of the close of business on the date of the consummation of the
relevant Transaction without any regard to any events or circumstances occurring
thereafter (such as changes in the trading price of any securities). Such
Profits shall be paid to Parent, for each type of consideration, within three
business days after the receipt by such Stockholder of such consideration. Any
payment of Profit under this Section 2(h) shall (AA) if paid in cash, be paid by
wire transfer of same day funds to an account designated by Parent, and (BB) if
paid through the transfer of securities or other non-cash consideration, be paid
through the delivery of such securities or other non-cash consideration,
suitably endorsed or otherwise documented for transfer (if applicable), to
Parent at its address set forth in Section 9.02 of the Merger Agreement.

          (ii) The "Profit" of such Stockholder shall mean, as of the close of
business on the date of consummation of a Transaction, the amount (if a positive
number) equal to (A) the product of (1) the Transaction Consideration (as
determined at such time) minus the Deal Price multiplied by (2) the number of
Subject Shares held by such Stockholder on the date of termination of this
Agreement in accordance with Section 8 (other than any Subject Shares sold,
transferred and delivered to Parent or its designee pursuant to Section 2(i)),
minus (B) any Profit Taxes (as defined in Section 2(h)(v)).

          (iii) "Transaction Consideration" shall mean, with respect to any
Transaction, the fair market value of the consideration which such Stockholder
(or its transferees) is entitled to receive (including any residual interest in
the Company retained immediately following consummation of a Transaction) in
respect of each share of Company Common Stock of such Stockholder (or its
transferees) in such Transaction, determined as of the close of business on the
date of the consummation of such Transaction; provided, however, that if
different types or amounts of consideration are to be paid (or retained) in a
Transaction, the "Transaction Consideration" shall be determined by dividing (1)
the aggregate fair market value of all the consideration (determined as of the
close of business on the date of the consummation of such Transaction received
or receivable by (including any residual interest in the Company retained by)
such Stockholder (or its transferees) (assuming for purposes of this calculation
that such Stockholder (or his transferees) has converted, exercised or exchanged
all convertible securities owned by any of them prior to the consummation of
such Transaction) by (2) the number of Subject Shares held by such Stockholder
(or its transferees) on the date of termination of this Agreement in accordance
with Section 8 (other than any Subject Shares sold, transferred and delivered to
Parent or its designee pursuant to Section 2(i)).

          (iv) For purposes of this Section 2(h), the "fair market value" of any
non-cash consideration consisting of:

               (A) securities listed on a national securities exchange or traded
     on the NASDAQ shall be equal to the average closing price per share of such
     security as


                                        6







     reported on such exchange or NASDAQ for the 10 trading days prior to the
     date of determination; and

               (B) consideration which is other than securities of the form
     specified in Section 2(h)(iv)(A) shall be determined by a nationally
     recognized independent investment banking firm mutually selected, within
     three business days after the event requiring selection of such investment
     banking firm, by Parent and the Stockholders, which determination shall be
     made by such investment banking firm within 15 business days after the date
     of such event; provided, however, that if Parent and the Stockholders do
     not agree within three business days after the date of such event as to the
     selection of an investment banking firm, then, by the end of the fifth
     business day after the date of such event, each of Parent, on the one hand,
     and the Stockholders, on the other hand, shall select a nationally
     recognized investment banking firm, which two investment banking firms
     shall jointly make such determination within 20 business days after the
     date of such event, or, if such two investment banking firms are unable to
     agree on such determination, the two investment banking firms shall, by the
     end of the 20th business day after the date of such event, select a third
     nationally recognized investment banking firm and notify such third
     investment banking firm in writing (with a copy to Parent and each
     Stockholder) of their respective determinations of the fair market value of
     such non-cash consideration, following which such third investment banking
     firm shall, within 15 business days after the date of its selection, notify
     Parent and each Stockholder in writing of its selection of one or the other
     of the two original determinations of the fair market value of such
     non-cash consideration; provided further, however, that the reasonable and
     customary fees and expenses of all such investment banking firms shall be
     borne equally by Parent, on the one hand, and the Stockholders, on the
     other hand. The determination of the investment banking firm shall be
     binding upon the parties.

          (v) The "Profit Taxes" of such Stockholder shall mean the net amount
of income taxes (U.S. federal, state and local) actually incurred by such
Stockholder solely as a result of the receipt of Profits by such Stockholder
determined taking into account any deduction, loss or offset against income
taxes attributable to the payment of Profits by such Stockholder to Parent in
accordance with the terms of this Agreement; provided, however, that solely for
the purposes of calculating Profit Taxes, clause (B) of the definition of
Profits contained in Section 2(h)(ii) shall be disregarded. Solely for purposes
of calculating Profit Taxes, in the case of a Stockholder that is treated as a
pass-through entity for U.S. federal, state or local income tax purposes, as the
case may be, the term "Stockholder" shall mean any direct member of such
pass-through entity and any indirect member of such pass-through entity that
owns its interest in such pass-through entity to the extent it owns such
interest through one or more other pass-through entities. For the purposes of
this clause, a "pass-through entity" includes without limitation, a partnership,
disregarded entity, trust, subchapter S corporation, controlled foreign
corporation, foreign person holding company or a passive foreign investment
company to the extent a qualifying electing fund election has been made with
respect to it.

          (vi) A "Parent Takeover Proposal" means any inquiry, proposal or offer
from Parent or any of its Subsidiaries relating to any direct or indirect
acquisition, in one transaction or a series of transactions, including any
merger, consolidation, tender offer, exchange offer, stock acquisition, asset
acquisition, binding share exchange, business combination,


                                        7







recapitalization, liquidation, dissolution, joint venture or similar
transaction, of (A) assets or businesses that constitute or represent 40% or
more of the total revenue, operating income, EBITDA or assets of the Company and
its Subsidiaries, taken as a whole, or (B) 40% or more of the outstanding shares
of Company Common Stock, or 40% or more of the outstanding shares of capital
stock of, or other equity or voting interests in, any of the Company's
Subsidiaries directly or indirectly holding, individually or taken together, the
assets or businesses referred to in clause (A) above.

          (vii) If any payment of any Stockholder's Profits described in this
Section 2(h) shall consist in whole or in part of a fractional share of
securities or other property, then the applicable Stockholder, in lieu of such
fractional share of securities or other property, shall pay to Parent a cash
adjustment in an amount equal to the fair market value of such fractional share
of securities or other property determined as of the close of business on the
date of the consummation of the Transaction to which such payment relates and
calculated pursuant to Section 2(h)(iv).

          (viii) Payment of any Stockholder's Profits described in this Section
2(h) shall not be in lieu of (but shall be in addition to) the fees and expenses
(including any Termination Fee) that may become payable to Parent pursuant to
Section 8.03 of the Merger Agreement and/or damages incurred in the event of a
breach of this Agreement or the Merger Agreement.

     (i) During the term of this Agreement (taking into account the penultimate
sentence of Section 8), at the request of Parent or Sub, such Stockholder shall
exercise, exchange or convert, as the case may be, or cause to be exercised,
exchanged or converted, as the case may be, such number and type of convertible
securities (including Stock Options, Warrants and Convertible Notes)
beneficially owned by such Stockholder and then exercisable, exchangeable or
convertible, as the case may be, as Parent or Sub, as the case may be, may
request, in each case within two business days following the later of (i) such
request and (ii) the last to occur of (A) the expiration or termination of any
waiting period (and any extension thereof) applicable to the relating Option
Exercise referred to below under any applicable competition, merger control,
antitrust or similar law or regulation and (B) the receipt of any other
regulatory approvals applicable to such Option Exercise; provided, however, that
Parent or Sub, as the case may be, shall purchase, upon the terms and subject to
the conditions set forth in the next following sentence of this Section 2(i),
all the shares of Company Common Stock issued upon such exercise, exchange or
conversion, as the case may be, of convertible securities; provided further,
however, that such Stockholder shall not be obligated so to exercise, exchange
or convert, as the case may be, any convertible security (including any Stock
Option, Warrant or Convertible Note) if the exercise price, exchange price or
conversion price, as the case may be, per share of Company Common Stock in
respect of such convertible security is above the Deal Price. At the request of
Parent or Sub (an "Option Exercise"), such Stockholder shall sell, transfer and
deliver or cause to be sold, transferred and delivered to Parent or Sub (or
their respective designees or assignees), as the case may be, and Parent or Sub
(or their respective designees or assignees), as the case may be, shall purchase
from, such Stockholder, all or any portion (as specified by Parent or Sub, as
the case may be) of the Subject Shares that consist of Company Common Stock of
such Stockholder within four business days following the later of (1) such
request and (2) the last to occur of (x) the expiration or termination of any
waiting period (and any extension thereof) applicable to such sale and purchase
under any applicable competition, merger control, antitrust


                                        8







or similar law or regulation and (y) the receipt of any other regulatory
approvals applicable to such sale and purchase, for a purchase price per share
equal to the Deal Price.

     (j) If, during the term of this Agreement (taking into account the
penultimate sentence of Section 8), Parent or one of its Affiliates offers to
purchase or otherwise acquire shares of Company Common Stock (the "Offer") in
connection with a Parent Takeover Proposal (including any amendment of the
Merger Agreement), then, at the request of Parent, each Stockholder hereby
agrees validly to tender (or cause the record owner of such shares, as
applicable, validly to tender), pursuant to and in accordance with the terms of
the Offer set forth in the acquisition agreement in respect of such Offer
(including any amendment of the Merger Agreement), but in no event later than
ten business days after the date on which Parent or such Affiliate commences the
Offer, all the Subject Shares and to not withdraw any of the Subject Shares so
tendered unless the Offer is terminated or has expired; provided, however, that
Parent (or such Affiliate) shall purchase all the Subject Shares so tendered at
a price per share of Company Common Stock equal to the Deal Price or any higher
price that may be paid in the Offer; provided further, however, that Parent's
(or such Affiliates') obligation to accept for payment and pay for the Subject
Shares in the Offer shall be subject to all the terms and conditions of the
Offer set forth in the acquisition agreement in respect of such Offer (including
any amendment of the Merger Agreement).

     SECTION 3. Grant of Irrevocable Proxy; Appointment of Proxy.

     (a) Each Stockholder hereby irrevocably grants to, and appoints, each of
Parent, Christopher C. Cambria, its Senior Vice President, Secretary and General
Counsel, and Michael T. Strianese, its Senior Vice President of Finance, in
their respective capacities as designees of Parent, and any individual who shall
hereafter succeed to any such office of Parent, and each of them individually,
such Stockholder's proxy and attorney-in-fact (with full power of substitution),
for and in the name, place and stead of such Stockholder, to vote all of such
Stockholder's Subject Shares, or grant a consent or approval in respect of such
Subject Shares, (i) in favor of the adoption of the Merger Agreement and the
approval of the terms thereof and of the Merger and each of the other
transactions contemplated by the Merger Agreement, (ii) against any Takeover
Proposal or any Frustrating Transaction, and (iii) otherwise in accordance with
Section 2. The proxy granted in this Section 3 shall expire upon the earlier of
the termination of this Agreement pursuant to Section 8 or the date that is 24
months and three days following the date of the granting of such proxy pursuant
hereto.

     (b) Each Stockholder represents and warrants that any proxies heretofore
given in respect of such Stockholder's Subject Shares were not irrevocable, and
that all such proxies hereby are revoked.

     (c) Each Stockholder hereby affirms that the irrevocable proxy set forth in
this Section 3 is given in connection with the execution of the Merger
Agreement, and that such irrevocable proxy is given to secure the performance of
the duties of such Stockholder under this Agreement. Each Stockholder hereby
further affirms that the irrevocable proxy is coupled with an interest and may
under no circumstances be revoked.


                                        9







     SECTION 4. Further Assurances. Each Stockholder shall, from time to time,
execute and deliver, or cause to be executed and delivered, such additional or
further consents, documents and other instruments as Parent may request for the
purpose of effectuating the matters covered by this Agreement, including the
grant of the proxies set forty in Section 3.

     SECTION 5. Additional Purchases. Each Stockholder agrees that any shares of
capital stock of the Company ("New Subject Shares") that such Stockholder
acquires beneficial ownership thereof after the date of this Agreement and prior
to the date of termination of this Agreement in accordance with Section 8, shall
be subject to the terms and conditions of this Agreement to the same extent as
if they constituted Subject Shares. If, at any time or from time to time after
the date of this Agreement and prior to the date of termination of this
Agreement in accordance with Section 8, any Stockholder acquires beneficial
ownership of New Subject Shares, but is not the record owner of such New Subject
Shares, then, contemporaneously with such acquisition, such Stockholder shall
cause the holder of record of such New Subject Shares (if such holder of record
is not then a party to this Agreement) to execute and deliver to Parent a
joinder agreement to be bound by the provisions of, and to become a party to,
this Agreement as a "Stockholder", in form and substance satisfactory to Parent.
Upon the occurrence of any of the events referred to in this Section 5, Schedule
A hereto shall be adjusted appropriately.

     SECTION 6. Certain Events. Each Stockholder agrees that this Agreement and
the obligations hereunder (including the obligations under Section 2(h)) shall
attach to such Stockholder's Subject Shares and shall be binding upon any Person
to which legal or beneficial ownership of such Subject Shares shall pass,
whether by operation of law or otherwise, including such Stockholder's heirs,
guardians, administrators or successors, and each Stockholder further agrees to
take all actions necessary to effectuate the foregoing. In the event of any
stock split, stock dividend, reclassification, merger, reorganization,
recapitalization or other change in the capital structure of the Company
affecting the capital stock of the Company, the number of Subject Shares listed
on Schedule A hereto opposite the name of each Stockholder shall be adjusted
appropriately and the Deal Price will be adjusted appropriately.

     SECTION 7. Assignment. Neither this Agreement nor any of the rights,
interests or obligations under this Agreement shall be assigned, in whole or in
part, by operation of law or otherwise, by any of the parties hereto without the
prior written consent of the other parties hereto, except that Parent may in its
sole discretion assign, in whole or in one or more parts, (a) any or all of its
rights, interests or obligations under this Agreement to any direct or indirect
wholly owned subsidiary of Parent, and (b) any of or all its rights, interests
and obligations under Section 2(h) or Section 2(i) to one or more third parties,
but no such assignment shall relieve Parent of any of its obligations under this
Agreement. Any purported assignment in violation of this Section 7 shall be
void. Subject to the preceding sentences of this Section 7, this Agreement shall
be binding upon, inure to the benefit of, and be enforceable by, the parties
hereto and their respective successors and assigns.

     SECTION 8. Termination. This Agreement shall terminate upon the earlier of
(a) the Effective Time and (b) the termination of the Merger Agreement in
accordance with its terms; provided, however, that the proxy granted in Section
3 shall terminate as provided in Section 3(a); provided further, however, that
if the Merger Agreement is terminated pursuant to Section 8.01(b)(iii), Section
8.01(c) or Section 8.01(f) of the Merger Agreement, then Sections 1, 2(h), 4,


                                       10







6, 7, 9, 10 and 11, as well as this Section 8, shall continue in full force and
effect for the duration of the Residual Period. The "Residual Period" means the
period beginning on the date of termination of the Merger Agreement and ending
12 months thereafter; provided, however, that if within such 12 month-period the
Company or any of its Subsidiaries enters into an Acquisition Agreement
contemplated under clause (i)(A)(2) of Section 2(h), then the Residual Period
shall not end until the date that is 24 months and three days after the
termination of the Merger Agreement. Notwithstanding the foregoing, this
Agreement shall not terminate (i) with respect to any Option Exercise made prior
to the date of termination of the Merger Agreement until the sale, transfer and
delivery of the Subject Shares with respect to such Option Exercise have been
effected, and (ii) with respect to Section 2(j) until the Offer is terminated or
has expired. No termination of this Agreement shall relieve any party hereto
from any liability for any breach of any provision of this Agreement prior to
termination.

     SECTION 9. General Provisions.

     (a) Amendments. This Agreement may not be amended, supplemented, waived or
otherwise modified or terminated, except upon the execution and delivery of a

provisions of this Agreement.

     (d) Counterparts; Effectiveness. This Agreement may be executed (including

invalid, illegal or incapable of being enforced by any rule of law or public
policy, all other conditions and provisions of this Agreement shall nevertheless
remain in full force and effect. Upon such determination that any term or other
provision is invalid, illegal or incapable of being enforced, the parties hereto
shall negotiate in good faith to modify this Agreement so as to effect the
original intent of the parties as closely as possible to the fullest extent
permitted by applicable law in an acceptable manner and to the end that the

with respect to the conversion, exercise or exchange of a security that is
convertible, exercisable or exchangeable shall be deemed to be fully satisfied.

     SECTION 10. Enforcement. The parties agree that irreparable damage would
occur if any of the provisions of this Agreement were not performed in

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 of this Agreement in any court of the United States
located in the State of New York or in any New York state court, this being in

request for leave from any such court, and (c) agrees that it will not bring any
action relating to this Agreement or the transactions contemplated by this

fullest extent permitted by Applicable Law, any right it may have to a trial by
jury in respect of any suit, action or other proceeding directly or indirectly
arising out of, under or in connection with this Agreement. Each party hereto
(a) certifies that no representative, agent or attorney of any other party has
represented, expressly or otherwise, that such party would not, in the event of
any action, suit or proceeding, seek to enforce the foregoing waiver, and (b)
acknowledges that it and the other parties hereto have been induced to enter
into this Agreement, by, among other things, the mutual waiver and
certifications in this Section 11.
