        The undersigned registrant hereby amends its current report on Form 8-K
originally filed with the Securities and Exchange Commission on June 24, 1999,
in order to correct a typographical error in the exchange ratio stated in the
Agreement and Plan of Merger (exhibit 2.1).

Item 5. Other Events

        Diamond Multimedia Systems, Inc., a Delaware corporation (the
"Registrant" or "Diamond") and S3 Incorporated, a Delaware corporation ("S3"),
have entered into an Agreement and Plan of Merger, dated as of June 21, 1999
(the "Merger Agreement"), whereby a wholly-owned subsidiary of S3 ("Merger Sub")
will be merged with and into Diamond, with Diamond as the surviving entity (the
"Merger").

               As a result of the Merger, the outstanding shares of common
stock, $0.001 par value per share, of Diamond (the "Diamond Common Stock") will
be converted into shares of Common Stock, $0.0001 par value per share, of S3
(the "S3 Common Stock") at an exchange ratio equal to 0.52 share of S3 Common
Stock for each share of Diamond Common Stock. As a result of the Merger, Diamond
will become a wholly-owned subsidiary of S3, and Diamond's board of directors
will consist of the directors of Merger Sub immediately prior to the effective
time of the Merger.

               The closing of the Merger is subject to certain conditions,
including the approval of the Common Stock holders of Diamond and S3 and the
receipt of customary antitrust clearance.

               S3 and Diamond entered into a Credit Agreement, dated as of June
10, 1999, and amended on June 14, 1999 (the "Credit Agreement"), pursuant to
which S3 agreed to make three (3) separate loans to Diamond in amounts not
exceeding $20.0 million in the aggregate. As of the date hereof, S3 has made two
of those three loans to Diamond in the aggregate amount of $10.0 million. In
connection with the aforesaid loans, Diamond issued to S3 three (3) warrants to
purchase an aggregate of 4,597,871 shares of Diamond Common Stock at exercise
prices ranging from $4.18 to $4.471875 per share.

               Copies of the Merger Agreement and the Credit Agreement are
attached as exhibits to this report and are incorporated herein by reference.

be fulfilled or waived in accordance with this Agreement or at such other time,
place and date as is mutually agreed to in writing by the parties hereto. The
date of the Closing is referred to in this Agreement as the "CLOSING DATE."

      Section 1.2 Conversion of Shares. (a) As of the Effective Time, by virtue
of the Merger and without any action on the part of the holders thereof:

      (i) Each share of common stock of Merger Subsidiary outstanding
immediately prior to the Effective Time shall be converted into and become one
validly issued, fully paid and nonassessable share of common stock, par value
$.001 per share, of the Surviving Corporation with the same rights, powers and
privileges as the shares so converted, and such shares shall constitute the only
outstanding shares of capital stock of the Surviving Corporation. From and after
the Effective Time, all certificates representing the common stock of Merger
Subsidiary shall be deemed for all purposes to represent the number of shares of
common stock of the Surviving Corporation into which they were converted in
accordance with this Section 1.2(a)(i).

      (ii) Each share of common stock, par value $.001 per share, of the Company
(a "COMPANY SHARE") held by the Company as treasury stock or owned by Acquirer
or any subsidiary of Acquirer, shall be cancelled, and no payment shall be made
with respect thereto.

      (iii) Each Company Share outstanding immediately prior to the Effective
Time shall, except as otherwise provided in Section 1.2(a)(ii), by virtue of the
Merger and without any action on the part of the holder thereof, be converted
into the right to receive 0.52 shares (the "EXCHANGE RATIO") of validly issued,
fully paid and nonassessable common stock, par value $.0001 per share, of
Acquirer ("ACQUIRER COMMON STOCK").

      (b) From and after the Effective Time, all Company Shares converted in
accordance with Section 1.2(a)(iii) shall no longer be outstanding and shall
automatically be canceled and retired and shall cease to exist, and each holder
of a certificate representing any such Company Shares shall cease to have any
rights with respect thereto, except the right to receive the Merger
Consideration (as defined below), as applicable, and any dividends payable
pursuant to Section 1.3(f).

      (c) The Acquirer Common Stock to be received as consideration pursuant to
the Merger by each holder of Company Shares (together with cash in lieu of
fractional shares of Acquirer Common Stock as specified below) is referred to
herein as the "MERGER CONSIDERATION."

      (d) For purposes of this Agreement, the word "SUBSIDIARY" when used with
respect to any Person means any other Person, whether incorporated or
unincorporated, of which (i) more than fifty percent (50%) of the securities or
other ownership interests or (ii) securities or other interests having by their
terms ordinary voting power to elect more than fifty percent (50%) of the board
of directors or others performing similar functions with respect to such
corporation or other organization, is directly owned



                                       2
<PAGE>   7
or controlled by such Person or by any one or more of its Subsidiaries. For
purposes of this Agreement, "PERSON" means an individual, a corporation, a
limited liability company, a partnership, an association, a trust or any other
entity or organization, including a government or political subdivision or any
agency or instrumentality thereof.

      Section 1.3 Surrender and Payment. (a) Prior to the Effective Time,
Acquirer shall appoint an agent reasonably acceptable to the Company (the
"EXCHANGE AGENT") for the purpose of exchanging certificates representing
Company Shares (the "CERTIFICATES") for the Merger Consideration. Acquirer will
make available to the Exchange Agent, as needed, the Merger Consideration to be
paid in respect of the Company Shares. Promptly after the Effective Time,
Acquirer will send, or will cause the Exchange Agent to send, to each holder of
record at the Effective Time of Company Shares a letter of transmittal for use
in such exchange (which shall specify that the delivery shall be effected, and
risk of loss and title shall pass, only upon proper delivery of the Certificates
to the Exchange Agent) in such form as the Company and Acquirer may reasonably
agree, for use in effecting delivery of Company Shares to the Exchange Agent.

      (b) Each holder of Company Shares that have been converted into a right to
receive the Merger Consideration, upon surrender to the Exchange Agent of a
Certificate, together with a properly completed letter of transmittal, will be
entitled to receive the Merger Consideration in respect of the Company Shares
represented by such Certificate. Until so surrendered, each such Certificate
shall, after the Effective Time, represent for all purposes only the right to
receive such Merger Consideration.

      (c) If any portion of the Merger Consideration is to be paid to a Person
other than the Person in whose name the Certificate is registered, it shall be a
condition to such payment that the Certificate so surrendered shall be properly
endorsed or otherwise be in proper form for transfer and that the Person
requesting such payment shall pay to the Exchange Agent any transfer or other
taxes required as a result of such payment to a Person other than the registered
holder of such Certificate or establish to the satisfaction of the Exchange
Agent that such tax has been paid or is not payable.

      (d) After the Effective Time, there shall be no further registration of
transfers of Company Shares. If, after the Effective Time, Certificates are
presented to the Surviving Corporation, they shall be canceled and exchanged for
the consideration provided for, and in accordance with the procedures set forth,
in this Article I.

      (e) Any portion of the Merger Consideration made available to the Exchange
Agent pursuant to Section 1.3(a) that remains unclaimed by the holders of
Company Shares one year after the Effective Time shall be returned to Acquirer,
upon demand, and any such holder who has not exchanged such holder's Company
Shares for the Merger Consideration in accordance with this Section 1.3 prior to
that time shall thereafter look only to Acquirer for payment of the Merger
Consideration in respect of such holder's Company Shares. Notwithstanding the
foregoing, Acquirer shall not be liable to any holder of Company Shares for any
amount paid to a public official pursuant to applicable abandoned property,
escheat or similar laws.

      (f) No dividends or other distributions with respect to Acquirer Common
Stock issued in the Merger shall be paid to the holder of any unsurrendered
Certificates until such Certificates are surrendered as provided in this Section
1.3. Subject to the effect of applicable laws, following such surrender, there
shall be paid, without interest, to the record holder of the Acquirer Common
Stock issued in exchange therefor (i) at the time of such surrender, all
dividends and other distributions payable in respect of such Acquirer Common
Stock with a record date after the Effective Time and a payment date on or prior
to the date of such surrender and not previously paid and (ii) at the
appropriate payment



                                       3
<PAGE>   8

date, the dividends or other distributions payable with respect to such Acquirer
Common Stock with a record date after the Effective Time but with a payment date
subsequent to such surrender. For purposes of dividends or other distributions
in respect of Acquirer Common Stock, all Acquirer Common Stock to be issued
pursuant to the Merger (but not options therefor issued pursuant to Section 1.4
unless actually exercised at the Effective Time) shall be entitled to dividends
pursuant to the immediately preceding sentence as if issued and outstanding as
of the Effective Time.

      Section 1.4 Stock Options. (a) At the Effective Time, each outstanding
option to purchase Company Shares (a "COMPANY STOCK OPTION") granted under the
Company's plans identified in the Schedule 1.4 as being the only compensation or
benefit plans or agreements pursuant to which Company Shares may be issued
(collectively, the "COMPANY STOCK OPTION PLANS"), whether vested or not vested,
shall be deemed assumed by Acquirer and shall thereafter be deemed to constitute
an option to acquire, on the same terms and conditions (including any provisions
for acceleration) as were applicable under such Company Stock Option prior to
the Effective Time (in accordance with the past practice of the Company with
respect to interpretation and application of such terms and conditions), the
number (rounded down to the nearest whole number) of shares of Acquirer Common
Stock determined by multiplying (x) the number of Company Shares subject to such
Company Stock Option immediately prior to the Effective Time by (y) the Exchange
Ratio, at a price per share of Acquirer Common Stock (rounded up to the nearest
whole cent) equal to (A) the exercise price per Company Share otherwise
purchasable pursuant to such Company Stock Option divided by (B) the Exchange
Ratio. The parties intend that the conversion of the Company Stock Options
hereunder will meet the requirements of Section 424(a) of the Code and this
Section 1.4(a) shall be interpreted consistent with such intention. Subject to
the terms of the Company Stock Options and the documents governing such Company
Stock Options, the Merger will not terminate or accelerate any Company Stock
Option or any right of exercise, vesting or repurchase relating thereto with
respect to Acquirer Common Stock acquired upon exercise of such assumed Company
Stock Option. Holders of Company Stock Options will not be entitled to acquire
Company Shares after the Merger. In addition, prior to the Effective Time, the
Company will make any amendments to the terms of such stock option or
compensation plans or arrangements that are necessary to give effect to the
transactions contemplated by this Section 1.4. Promptly following the Effective
Time, Acquirer will issue to each holder of an outstanding Company Stock Option
a document evidencing the foregoing assumption of such Company Stock Option by
Acquirer.

      (b) Acquirer shall take all corporate action necessary to reserve for
issuance a sufficient number of shares of Acquirer Common Stock for delivery
pursuant to the terms set forth in this Section 1.4.

      (c) At the Effective Time, each outstanding purchase right with respect to
all open offering periods under the Company's Employee Stock Purchase Plan (each
an "ASSUMED PURCHASE RIGHT") shall be assumed by Parent. Each Assumed Purchase
Right shall continue to have, and be subject to, the terms and conditions set
forth in the Company's Employee Stock Purchase Plan and the documents governing
the Assumed Purchase Right, except that the purchase price of such shares of
Acquirer Common Stock for each respective purchase date under each Assumed
Purchase Right shall be the lower of (i) the quotient determined by dividing
eighty-five percent (85%) of the fair market value of the Company Common Stock
on the offering date of each assumed offering period by the Exchange Ratio or
(ii) eighty-five percent (85%) of the fair market value of the Acquirer Common
Stock on each purchase date of each assumed offering period occurring after the
Effective Time (with the number of shares rounded down to the nearest whole
share and the purchase price rounded up to the nearest whole cent). The Assumed
Purchase Rights shall be exercised at such times following the Effective Time as
set forth in the Company's Employee Stock Purchase Plan, and each participant
shall, accordingly, be issued shares of Acquirer Common Stock at such times. The
Company's Employee Stock Purchase Plan shall terminate with the exercise of the
last Assumed Purchase Right, and no additional purchase rights shall



                                       4
<PAGE>   9
be granted under the Company's Employee Stock Purchase Plan following the
Effective Time. Acquirer agrees that from and after the Effective Time,
employees of the Company may participate in Acquirer's employee stock purchase
plan, subject to the terms and conditions of such plan.

      (d) At the Effective Time, each award or account (including restricted
stock, stock equivalents and stock units, but excluding Company Stock Options
and Assumed Purchase Rights) outstanding as of the date hereof ("COMPANY AWARD")
that has been established, made or granted under any employee incentive or
benefit plans, programs or arrangements and non-employee director plans
maintained by the Company on or prior to the date hereof which provide for
grants of equity-based awards or equity-based accounts shall be amended or
converted into a similar instrument of Acquirer, in each case with such
adjustments to the terms and conditions of such Company Awards as are
appropriate to preserve the value inherent in such Company Awards with no
detrimental effects on the holders thereof. The other terms and conditions of
each Company Award, and the plans or agreements under which they were issued,
shall continue to apply in accordance with their terms and conditions, including
any provisions for acceleration (as such terms and conditions have been
interpreted and applied by the Company in accordance with its past practice).

      (e) At the Effective Time, Acquirer shall file with the Securities and
Exchange Commission (the "SEC") a registration statement on an appropriate form
or a post-effective amendment to a previously filed registration statement under
the Securities Act of 1933, as amended (the "1933 ACT"), with respect to the
Acquirer Common Stock subject to options and other equity-based awards issued
pursuant to this Section 1.4, and shall use all commercially reasonable efforts
to maintain the current status of the prospectus contained therein, as well as
comply with any applicable state securities or "blue sky" laws, for so long as
such options or other equity-based awards remain outstanding.

      Section 1.5 Adjustments. If at any time during the period between the date
of this Agreement and the Effective Time, any change in the outstanding shares
of capital stock of Acquirer or the Company (other than as contemplated in
Section 3.2 or Section 4.2 or permitted under this Agreement) shall occur,
including, without limitation, by reason of any reclassification,
recapitalization, stock split or combination, exchange or readjustment of
shares, or any stock dividend thereon with a record date during such period, the
Merger Consideration shall be appropriately adjusted.

      Section 1.6 Fractional Shares. (a) No fractional shares of Acquirer Common
Stock shall be issued in the Merger. All fractional shares of Acquirer Common
Stock that a holder of Company Shares would otherwise be entitled to receive as
a result of the Merger shall be aggregated and if a fractional share results
from such aggregation, such holder shall be entitled to receive from the
Exchange Agent, in lieu thereof, an amount in cash determined by multiplying the
closing price of one share of Acquirer Common Stock on the Nasdaq National
Market ("NNM") on the Closing Date by the fraction of a share of Acquirer Common
Stock to which such holder would otherwise have been entitled. The parties
acknowledge that payment of the cash consideration in lieu of issuing fractional
shares was not separately bargained for consideration but merely represents a
mechanical rounding off for purposes of simplifying the corporate and accounting
problems that would otherwise be caused by the issuance of fractional shares. As
promptly as practicable after the determination of the amount of cash, if any,
to be paid to holders of fractional interests, the Exchange Agent shall so
notify Acquirer, and Acquirer shall deposit or cause to be deposited with the
Exchange Agent such amount and shall cause the Exchange Agent to make available
such amounts to such holders of fractional interests without interest.

      Section 1.7 Withholding Rights. Each of the Surviving Corporation and
Acquirer shall be entitled to deduct and withhold from the consideration
otherwise payable to any person pursuant to this Article I such amounts as it is
required to deduct and withhold with respect to the making of such



                                       5
<PAGE>   10
payment under any provision of federal, state, local or foreign tax law. To the
extent that amounts are so withheld by the Surviving Corporation or Acquirer, as
the case may be, such withheld amounts shall be treated for all purposes of this
Agreement as having been paid to the holder of the Company Shares in respect of
which such deduction and withholding was made by the Surviving Corporation or
Acquirer, as the case may be.

      Section 1.8 Lost Certificates. If any Certificate shall have been lost,
stolen or destroyed, upon the making of an affidavit of that fact by the person
claiming such Certificate to be lost, stolen or destroyed and, if required by
the Exchange Agent, the posting by such person of a bond, in such reasonable
amount as the Exchange Agent may direct, as indemnity against any claim that may
be made against it, the Surviving Corporation or the Exchange Agent with respect
to such Certificate, the Exchange Agent will issue in exchange for such lost,
stolen or destroyed Certificate the Merger Consideration to be paid in respect
of the Company Shares represented by such Certificate as contemplated by this
Article I.


                                   ARTICLE II
                           CERTAIN GOVERNANCE MATTERS

      Section 2.1 Acquirer Board of Directors. At the Effective Time, Acquirer
shall cause the Board of Directors of Acquirer to consist of either five or
seven directors (with the total number of directors to be established by
Acquirer), a majority of one of whom shall be directors of Acquirer prior to the
Effective Time and the remainder of whom shall be directors designated by the
Company after consultation with the Acquirer (the "COMPANY BOARD DESIGNEES").

      Section 2.2 Acquirer Officers. The officers of the Acquirer after the
Effective Time shall be determined by the Board of Directors of the Acquirer

respective Chief Executive Officers of Acquirer and the Company, except that Mr.
Kenneth F. Potashner shall be the Chairman and Chief Executive Officer of
Acquirer and Mr. William J. Schroeder shall be offered the position of President
and Chief Operating Officer of Acquirer, to hold office from and after the
Effective Time (assuming such individuals desire to continue in such positions
as of such date) until their respective successors are duly appointed and
qualify in the manner provided in the By-Laws of the Acquirer or as otherwise
provided by law or their earlier resignation or removal.

      Section 2.3 Certificate of Incorporation of the Surviving Corporation. The
certificate of incorporation of Merger Subsidiary in effect at the Effective
Time shall be the certificate of incorporation of the Surviving Corporation
until amended in accordance with applicable law.

      Section 2.4 By-Laws of the Surviving Corporation. Subject to Section 6.3,
the by-laws of Merger Subsidiary in effect at the Effective Time shall be the
by-laws of the Surviving Corporation until amended in accordance with applicable
law.

      Section 2.5 Directors and Officers of the Surviving Corporation. Subject
to Section 6.3, from and after the Effective Time, until successors are duly

directors of Merger Subsidiary at the Effective Time shall be the directors of
the Surviving Corporation, and (b) the officers of the Company at the Effective
Time shall be the officers of the Surviving Corporation.

                                   ARTICLE III
                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

      Except as disclosed in a letter delivered by the Company to Acquirer
immediately prior to the execution of this Agreement and signed by a duly
authorized officer of the Company (the "COMPANY DISCLOSURE LETTER"), the Company
represents and warrants to Acquirer as follows:

      Section 3.1 Organization and Qualification. The Company is a corporation
duly organized, validly existing and in good standing under the laws of the
State of Delaware and has all requisite corporate power and authority to own,
lease and operate its respective properties and to carry on its business as now
being conducted.

      The Company is qualified to do business as a foreign corporation and is in
good standing under the laws of each state or other jurisdiction in which the
nature of its business requires such qualification, except where the failure to
be so qualified or in good standing which, taken together with all other such
failures, would not have a Material Adverse Effect on the Company. For purposes
of this Agreement, the term "MATERIAL ADVERSE EFFECT" means, when used in
connection with the Company or Acquirer, as the case may be, any change,
violation, inaccuracy, circumstance or effect that is materially adverse to the
business, properties, assets (including intangible assets), liabilities,
capitalization or financial condition of either party and its Subsidiaries,
taken as a whole, as the case may be; provided, however, that the following
shall not be taken into account in determining whether there has been or could
or would be a "Material Adverse Effect" on or with respect to a party: (i) any
occurrences relating to the economy of the United States in general or the
economies in which such entity operates or the multimedia and connectivity
products for personal computer industry in general and not specifically relating
to such party, (ii) the delay or cancellation of orders for such party's
products from customers or distributors (or other resellers) directly
attributable to the announcement of this Agreement or the pendency of the
Merger, (iii) the lack of or delay in availability of components or raw
materials from such party's suppliers directly attributable to the announcement
of this Agreement or the pendency of the Merger, (iv) any litigation brought or
threatened against a party or any officer or member of the Board of Directors of
such party in respect of this Agreement or the Merger (including any stockholder
class action litigation arising from allegations or a breach of fiduciary duty
relating to this Agreement), (v) the loss of employees as a result of reductions
in force that are mutually agreed upon by the Company and Acquirer, (vi) the
loss of employees with titles of director or officer in an amount not in excess
of fifteen percent (15%) of the number of such employees as of the date of this
Agreement or the loss of employees with titles other than director or officer in
an amount not in excess of fifteen percent (15%) of the number of such employees
as of the date of this Agreement (excluding in each case employees lost pursuant
to reductions in force described in clause (v) and in the case of employees with
titles of director or officer losses resulting solely from a failure by Acquirer
to offer commercially reasonable retention incentives to such employees prior to
the Closing), and (vii) changes in trading prices for such party's securities.

      The Company has made available to Acquirer true and complete copies of the
Company's certificate of incorporation and by-laws, as amended to the date
hereof.

      Section 3.2 Capitalization. The authorized capital stock of the Company
consists of 75,000,000 Company Shares and 8,000,000 shares of Preferred Stock,
par value $.001 per share, all of which shares of Preferred Stock have not been
designated. As of May 31, 1999, (i) 35,573,024 Company Shares were issued and
outstanding, (ii) no shares of Preferred Stock were issued and outstanding,
(iii) no Company Shares were held in the treasury of the Company or any of its
Subsidiaries, and (iv) 9,891,497 Company Shares are reserved for issuance
pursuant to the Company Option Plans, of which stock options to



                                       7
<PAGE>   12
purchase 8,650,905 Company Shares have been granted (of which options to
purchase an aggregate of 1,954,324 shares were exercisable). As of May 31, 1999,
1,050,000 Company Shares were reserved under the Company's Employee Stock
Purchase Plan, of which 649,422 have been granted. All the outstanding shares of
the Company's capital stock are, and all Company Shares that may be issued
pursuant to the exercise of outstanding employee stock options will be, when
issued in accordance with the terms thereof, duly authorized, validly issued,
fully paid and non-assessable. Except as disclosed in the Company Disclosure
Letter and except for changes since the close of business on May 31, 1999
resulting from the exercise of employee stock options outstanding on such date
or options granted as permitted by Section 5.1, there are outstanding (x) no
shares of capital stock or other voting securities of the Company, (y) no
securities of the Company convertible into or exchangeable for shares of capital
stock or voting securities of the Company, and (z) no options, warrants or other
rights to acquire from the Company, and no preemptive or similar rights,
subscription or other rights, convertible securities, agreements, arrangements
or commitments of any character, relating to the capital stock of the Company,
obligating the Company to issue, transfer or sell, any capital stock, voting
securities or securities convertible into or exchangeable for capital stock or
voting securities of the Company or obligating the Company to grant, extend or
enter into any such option, warrant, subscription or other right, convertible
security, agreement, arrangement or commitment (the items in clauses (x), (y)
and (z) being referred to collectively as the "COMPANY SECURITIES"). There are
no outstanding obligations of the Company or any of its Subsidiaries to
repurchase, redeem or otherwise acquire any Company Securities. There are not as
of the date hereof and there will not be at the Effective Time any stockholder
agreements, voting trusts or other agreements or understandings to which the
Company or any of its Subsidiaries is a party or by which it is bound relating
to the voting of any shares of the capital stock of the Company or any
agreements, arrangements, or other understandings to which the Company or any of
its Subsidiaries is a party or by which it is bound that will limit in any way
the solicitation of proxies by or on behalf of the Company from, or the casting
of votes by, the stockholders of the Company with respect to the Merger.

      Section 3.3 Authority. The Company has full corporate power and authority
to execute and deliver this Agreement and, subject to the requisite approval of
its stockholders, to consummate the transactions contemplated hereby. The
execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby have been duly and validly authorized and
approved by the Company's Board of Directors, and other than the requisite
approval by its stockholders, no other corporate proceedings are necessary to
authorize this Agreement or the consummation of the transactions contemplated
hereby. This Agreement has been duly and validly executed and delivered by the
Company and, assuming this Agreement constitutes a legal, valid and binding
agreement of the other parties hereto, it constitutes a legal, valid and binding
agreement of the Company, enforceable against it in accordance with its terms,
except (i) as limited by applicable bankruptcy, insolvency, reorganization,
moratorium and other laws of general application affecting enforcement of
creditors' rights generally and (ii) as limited by laws relating to the
availability of specific performance, injunctive relief or other equitable
remedies.

      Section 3.4 Governmental Authorization. The execution, delivery and
performance by the Company of this Agreement and the consummation of the Merger
by the Company require no consent of, or filing with, any governmental body,
agency, official or authority other than (a) the filing of a certificate of
merger in accordance with Delaware Law, (b) compliance with any applicable
requirements of the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the
"HSR ACT"), (c) compliance with any applicable requirements of the Securities
Exchange Act of 1934, as amended, and the rules and regulations promulgated
thereunder (the "EXCHANGE ACT"), (d) compliance with any applicable requirements
of the 1933 Act and state securities laws, and (e) other actions or filings
which if not taken or made would not, individually or in the aggregate, have a
Material Adverse Effect on the Company.

      Section 3.5 Non-Contravention. The execution, delivery and performance by
the Company of this Agreement and the consummation by the Company of the
transactions contemplated hereby do not and will not (a) assuming compliance
with the matters referred to in Section 3.3, contravene or conflict with the
certificate of incorporation or by-laws of the Company, (b) assuming compliance
with the matters referred to in Section 3.4, contravene or conflict with or
constitute a violation of any provision of any law, regulation, judgment,
injunction, order or decree binding upon or applicable to the Company or any of
its Subsidiaries, (c) constitute a default under or give rise to a right of
termination, cancellation or acceleration of any right or obligation of the
Company or any of its Subsidiaries or to a loss of any benefit to which the
Company or any of its Subsidiaries is entitled under any provision of any
agreement, contract or other instrument binding upon the Company or any of its
Subsidiaries or any license, franchise, permit or other similar authorization
held by the Company or any of its Subsidiaries, or (d) result in the creation or
imposition of any Lien on any asset of the Company or any of its Subsidiaries,
except for such contraventions, conflicts or violations referred to in clause
(b) or defaults, rights of termination, cancellation or acceleration, or losses
or Liens referred to in clause (c) or (d) that would not, individually or in the
aggregate, have a Material Adverse Effect on the Company. For purposes of this
Agreement, "LIEN" means, with respect to any asset of the Company or Acquirer,
as the case may be, any mortgage, lien, pledge, charge, security interest or
encumbrance of any kind in respect of such asset other than any such mortgage,
lien, pledge, charge, security interest or encumbrance (i) for Taxes (as defined
in Section 3.13) not yet due or being contested in good faith (and for which
adequate accruals or reserves have been established on the Company Balance Sheet
or the Acquirer Balance Sheet (as such terms are defined in Sections 3.8 and
4.8, respectively), as the case may be) or (ii) which is a carriers',
warehousemen's, mechanics', materialmen's, repairmen's or other like lien
arising in the ordinary course of business. Except as disclosed in the Company
Disclosure Letter, neither the Company nor any Subsidiary of the Company is a
party to any agreement that expressly limits the ability of the Company or any
Subsidiary of the Company, or would limit Acquirer or any Subsidiary of Acquirer
after the Effective Time, to compete in or conduct any line of business or
compete with any Person or in any geographic area or during any period of time
except to the extent that any such limitation, individually or in the aggregate,
would not be reasonably likely to have a Material Adverse Effect on Acquirer
after the Effective Time.

      Section 3.6 Subsidiaries. Each of the Company's Subsidiaries is a
corporation duly organized, validly existing and in good standing under the laws
of its jurisdiction of incorporation and has all requisite corporate power and
authority to own, lease and operate its properties and to carry on its business
as it is now being conducted. Each of the Subsidiaries is duly qualified as a
foreign corporation to do business, and is in good standing, in each
jurisdiction where the character of its properties owned or leased or the nature
of its activities makes such qualification necessary, except where the failure
to be so qualified or in good standing would not have a Material Adverse Effect
on the Company. Exhibit 21 to the Company's Annual Report on Form 10-K for the
fiscal year ended December 31, 1998 (the "1998 10-K"), as filed with SEC, lists
the only Subsidiaries of the Company at December 31, 1998, and all Subsidiaries
of the Company thereafter formed or acquired are listed in the Company
Disclosure Letter. All of the outstanding shares of capital stock of the
Subsidiaries are validly issued, fully paid and nonassessable and, other than
directors' qualifying shares in the case of foreign Subsidiaries, are owned by
the Company or by a wholly owned Subsidiary of the Company free and clear of all
material liens, claims, charges or encumbrances, and there are no irrevocable
proxies with respect to such shares. Except as set forth in the Company
Disclosure Letter and except for the capital stock of its Subsidiaries, the
Company does not own, directly or indirectly, any capital stock or other
ownership interest in any corporation, partnership, joint venture, limited
liability company or other entity which is material to the business of the

amendment to any such Company Employee Plan that was made on or after the date

Employee Plan provides post-retirement health and medical, life or other

Subsidiaries (other than benefit coverage mandated by applicable statute,
including benefits provided pursuant to the Consolidated Omnibus Budget
Reconciliation Act of 1985, as codified in Code section 4980B and ERISA sections
601 et seq., as amended from time to time ("COBRA")).

Subsidiaries, in each case, with respect to any matters relating to or arising
out of any Environmental Law; (ii) the Company and its Subsidiaries are and have
been in compliance with all Environmental Laws; and (iii) there are no
liabilities of or relating to the Company or any of its Subsidiaries relating to

Acquirer or any agreements, arrangements, or other understandings to which
Acquirer or any of its Subsidiaries is a party or by which it is bound that will
limit in any way the solicitation of proxies by or on behalf of Acquirer from,
or the casting of votes by, the stockholders of Acquirer with respect to the
Merger.

corporate power and authority to execute and deliver this Agreement and, subject
to the requisite approval of its stockholders, to consummate the transactions

Acquirer's Board of Directors (clauses (i), (ii), (iii) and (iv) being the
"ACQUIRER STOCKHOLDER APPROVAL"), no other corporate proceedings are necessary
to authorize this Agreement or the consummation of the transactions contemplated
hereby. This Agreement has been duly and validly executed and delivered by
Acquirer and Merger Subsidiary and, assuming this Agreement constitutes a legal,
valid and binding agreement of the other parties hereto, it constitutes a legal,
valid and binding agreement of Acquirer, enforceable against it in accordance
with its terms, except (i) as limited by applicable bankruptcy, insolvency,
reorganization, moratorium and other laws of general application affecting
enforcement of creditors' rights generally and (ii) as limited by laws relating
to the availability of specific performance, injunctive relief or other
equitable remedies.

      Section 4.4 Governmental Authorization. The execution, delivery and
performance by Acquirer and Merger Subsidiary of this Agreement and the
consummation of the Merger by Acquirer and Merger Subsidiary require no consent
of, or filing with, any governmental body, agency, official or authority other
than (a) the filing of a certificate of merger in accordance with Delaware Law,
(b) compliance with any applicable requirements of the HSR Act, (c) compliance
with any applicable requirements of the Exchange Act, (d) compliance with any
applicable requirements of the 1933 Act and state securities laws, and (e) other
actions or filings which if not taken or made would not, individually or in the
aggregate, have a Material Adverse Effect on Acquirer.

      Section 4.5 Non-Contravention. The execution, delivery and performance by
Acquirer and Merger Subsidiary of this Agreement and the consummation by
Acquirer and Merger Subsidiary of the transactions contemplated hereby do not
and will not (a) assuming compliance with the matters referred to in Section
4.3, contravene or conflict with the certificate of incorporation or by-laws of
Acquirer or Merger Subsidiary, (b) assuming compliance with the matters referred
to in Section 4.4, contravene or conflict with or constitute a violation of any
provision of any law, regulation, judgment, injunction, order or decree binding
upon or applicable to Acquirer or any of its Subsidiaries, (c) constitute a
default under or give rise to a right of termination, cancellation or
acceleration of any right or obligation of Acquirer or any of its Subsidiaries
or to a loss of any benefit to which Acquirer or any of its Subsidiaries is
entitled under any provision of any agreement, contract or other instrument
binding upon Acquirer or any of its Subsidiaries or any license, franchise,
permit or other similar authorization held by Acquirer or any of its
Subsidiaries, or (d) result in the creation or imposition of any Lien on any
asset of Acquirer or any of its Subsidiaries, except for such contraventions,
conflicts or violations referred to in clause (b) or defaults, rights of
termination, cancellation or acceleration, or losses or Liens referred to in
clause (c) or (d) that would not, individually or in the aggregate, have a
Material Adverse Effect on Acquirer. Except as disclosed in the Acquirer
Disclosure Letter, neither Acquirer nor any Subsidiary of Acquirer is a party to
any agreement that expressly limits the ability of Acquirer or any Subsidiary of
Acquirer to compete in or conduct any line of business or compete with any
Person or in any geographic area or during any period of time except to the
extent that any such limitation, individually or in the aggregate, would not be
reasonably likely to have a Material Adverse Effect on Acquirer after the
Effective Time.

      Section 4.6 Subsidiaries. Each of Acquirer's Subsidiaries is a corporation
duly organized, validly existing and in good standing under the laws of its
jurisdiction of incorporation and has all requisite



                                       18
<PAGE>   23
corporate power and authority to own, lease and operate its properties and to
carry on its business as it is now being conducted. Each of the Subsidiaries is
duly qualified as a foreign corporation to do business, and is in good standing,
in each jurisdiction where the character of its properties owned or leased or
the nature of its activities makes such qualification necessary, except where
the failure to be so qualified or in good standing would not have a Material
Adverse Effect on Acquirer. Exhibit 21 to Acquirer's Annual Report on Form 10-K
for the fiscal year ended December 31, 1998 (the "ACQUIRER 10-K"), as filed with
the SEC, lists the only Subsidiaries of Acquirer at December 31, 1998, and,
except for Merger Subsidiary, all Subsidiaries of Acquirer thereafter formed or
acquired are listed in the Acquirer Disclosure Letter. All of the outstanding
shares of capital stock of the Subsidiaries are validly issued, fully paid and
nonassessable and, other than directors' qualifying shares in the case of
foreign Subsidiaries, are owned by Acquirer or by a wholly owned Subsidiary of
Acquirer free and clear of all material liens, claims, charges or encumbrances,
and there are no irrevocable proxies with respect to such shares. Except as set
forth in the Acquirer Disclosure Letter and except for the capital stock of its
Subsidiaries, Acquirer does not own, directly or indirectly, any capital stock
or other ownership interest in any corporation, partnership, joint venture,
limited liability company or other entity which is material to the business of
Acquirer and its Subsidiaries, taken as a whole. There are no material
restrictions on Acquirer to vote the stock of any of its Subsidiaries.

      Section 4.7 SEC Filings. (a) Acquirer has made available to the Company
(i) its annual reports on Form 10-K for its fiscal years ended December 31,
1996, 1997 and 1998, (ii) its quarterly reports on Form 10-Q for its quarter
ended March 31, 1999, (iii) its proxy or information statements relating to
meetings of, or actions taken without a meeting by, the stockholders of Acquirer
held since December 31, 1998, and (iv) all of its other reports, statements,
schedules and registration statements filed with the SEC since December 31, 1998
(the documents referred to in this Section 4.7(a) being referred to collectively
as the "ACQUIRER SEC DOCUMENTS"). Acquirer's quarterly report on Form 10-Q for
its fiscal quarter ended March 31, 1998 is referred to herein as the "ACQUIRER
10-Q."

      (b) As of its filing date, each Acquirer SEC Document complied as to form
in all material respects with the applicable requirements of the Exchange Act
and the 1933 Act.

      (c) As of its filing date, each Acquirer SEC Document filed pursuant to
the Exchange Act did not contain any untrue statement of a material fact or omit
to state any material fact necessary in order to make the statements made
therein, in the light of the circumstances under which they were made, not
misleading.

      (d) Each such registration statement, as amended or supplemented, if
applicable, filed pursuant to the 1933 Act as of the date such statement or
amendment became effective did not contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein not misleading.

      Section 4.8 Financial Statements. The audited consolidated financial
statements and unaudited consolidated interim financial statements of Acquirer
(including any related notes and schedules) included in its annual reports on
Form 10-K and the quarterly report on Form 10-Q referred to in Section 4.7
fairly present in all material respects, in conformity with GAAP applied on a
consistent basis (except as may be indicated in the notes thereto), the
consolidated financial position of Acquirer and its consolidated Subsidiaries as
of the dates thereof and their consolidated results of operations and changes in
financial position for the periods then ended (subject to normal year-end
adjustments and the absence of notes in the case of any unaudited interim
financial statements). For purposes of this Agreement, "ACQUIRER BALANCE SHEET"
means the consolidated balance sheet of Acquirer as of March 31, 1999 set forth
in Acquirer 10-Q and "ACQUIRER BALANCE SHEET DATE" means March 31, 1999.

      Section 4.9 Disclosure Documents. (a) The Joint Proxy Statement/Prospectus
to be filed with the SEC in connection with the Merger and the Form S-4 to be
filed under the 1933 Act relating to the issuance of Acquirer Common Stock in
the Merger, and any amendments or supplements thereto, will, when filed, subject
to the last sentence of Section 4.9(b), comply as to form in all material
respects with the requirements of the Exchange Act and the 1933 Act.

      (b) Neither the Joint Proxy Statement/Prospectus to be filed with the SEC,
nor any amendment or supplement thereto, will, at the date the Joint Proxy
Statement/Prospectus or any such amendment or supplement is first mailed to
stockholders of Acquirer or at the time such stockholders vote on the adoption
and approval of this Agreement and the transactions contemplated hereby, contain
any untrue statement of a material fact or omit to state any material fact
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading. Neither the Form S-4
nor any amendment or supplement thereto will at the time it becomes effective
under the 1933 Act or at the Effective Time contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein not misleading. No representation or
warranty is made by Acquirer in this Section 4.9 with respect to statements made
or incorporated by reference therein based on information supplied by the
Company for inclusion or incorporation by reference in the Joint Proxy
Statement/Prospectus or the Form S-4.

      Section 4.10 Absence of Certain Changes. Except as set forth in the
Acquirer Disclosure Letter, since Acquirer Balance Sheet Date, Acquirer and its
Subsidiaries have conducted their business in the ordinary course consistent
with past practice and there has not been:

      (a) any event, occurrence or development of a state of circumstances or
facts which has had or reasonably would be expected to have, individually or in
the aggregate, a Material Adverse Effect on Acquirer;

      (b) any declaration, setting aside or payment of any dividend or other

or other ownership interests in, Acquirer or any of its Subsidiaries;

      (c) any amendment of any material term of any outstanding security of
Acquirer or any of its Subsidiaries;

any of its Subsidiaries of any contract or other right, in either case, material
to Acquirer and its Subsidiaries taken as a whole, other than transactions,
commitments, contracts, agreements or settlements (including without limitation
settlements of litigation and tax proceedings) in the ordinary course of
business consistent with past practice, those contemplated by this Agreement, or
as agreed to in writing by the Company;

      (e) any change in any method of accounting or accounting practice (other
than any change for tax purposes) by Acquirer or any of its Subsidiaries, except
for any such change which is not significant or which is required by reason of a
concurrent change in GAAP; or

      (f) any (i) grant of any severance or termination pay to (or amendment to
any such existing arrangement with) any director, officer or employee of
Acquirer or any of its Subsidiaries, (ii) entering



                                       20
<PAGE>   25
into of any employment, deferred compensation or other similar agreement (or any
amendment to any such existing agreement) with any director, officer or employee
of Acquirer or any of its Subsidiaries, (iii) increase in benefits payable under
any existing severance or termination pay policies or employment agreements or
(iv) increase in (or amendments to the terms of) compensation, bonus or other
benefits payable to directors, officers or employees of Acquirer or any of its

practice, as permitted by this Agreement, or as agreed to in writing by the
Company.

      Section 4.11 No Undisclosed Material Liabilities. There are no liabilities
of Acquirer or any Subsidiary of Acquirer of any kind whatsoever, whether

      (a) liabilities disclosed or provided for in Acquirer Balance Sheet or in
the notes thereto;

      (b) liabilities which in the aggregate would not reasonably be expected to

filed prior to the date hereof, there is no action, suit, investigation or
proceeding pending against, or to the knowledge of Acquirer threatened against
or affecting, Acquirer or any of its Subsidiaries or any of their respective
properties before any court or arbitrator or any governmental body, agency or
official which would reasonably be expected to have a Material Adverse Effect on
Acquirer.

      Section 4.13 Taxes. Except as set forth in the Acquirer Balance Sheet
(including the notes thereto) or as otherwise set forth in the Acquirer
Disclosure Letter and except as would not, individually or in the aggregate,
have a Material Adverse Effect on Acquirer, (i) all Acquirer Tax Returns
required to be filed with any taxing authority by, or with respect to, Acquirer
and its Subsidiaries have been filed in accordance with all applicable laws;
(ii) Acquirer and its Subsidiaries have timely paid all Taxes shown as due and
payable on Acquirer Tax Returns that have been so filed, and, as of the time of
filing, Acquirer Tax Returns correctly reflected the facts regarding the income,
business, assets, operations, activities and the status of Acquirer and its
Subsidiaries (other than Taxes which are being contested in good faith and for
which adequate reserves are reflected on the Acquirer Balance Sheet); (iii)
Acquirer and its Subsidiaries have made provision for all Taxes payable by
Acquirer and its Subsidiaries for which no Acquirer Tax Return has yet been
filed; (iv) the charges, accruals and reserves for Taxes with respect to
Acquirer and its Subsidiaries reflected on the Acquirer Balance Sheet are
adequate under GAAP to cover the Tax liabilities accruing through the date
thereof; (v) there is no action, suit, proceeding, audit or claim now proposed
or pending against or with respect to Acquirer or any of its Subsidiaries in
respect of any Tax where there is a reasonable possibility of an adverse
determination; and (vi) to the best of Acquirer's knowledge and belief, neither
Acquirer nor any of its Subsidiaries is liable for any Tax imposed on any entity
other than such Person, except as the result of the application of Treas. Reg.
Section 1.1502-6 (and any comparable provision of the tax laws of any state,
local or foreign jurisdiction) to the affiliated group of which Acquirer is the
common parent.

      Section 4.14 Employee Benefit Plans. (a) Prior to the date hereof,
Acquirer has provided the Company with a list (set forth in the Acquirer
Disclosure Letter) identifying each material "employee



                                       21
<PAGE>   26
benefit plan," as defined in Section 3(3) of ERISA, each material employment,
severance or similar contract, plan, arrangement or policy applicable to any
director, former director, employee or former employee of Acquirer and each
material plan or arrangement (written or oral), providing for compensation,
bonuses, profit-sharing, stock option or other stock related rights or other
forms of incentive or deferred compensation, vacation benefits, insurance
coverage (including any self-insured arrangements), health or medical benefits,
disability benefits, workers' compensation, supplemental unemployment benefits,
severance benefits and post-employment or retirement benefits (including
compensation, pension, health, medical or life insurance benefits) which is
maintained, administered or contributed to by Acquirer and covers any employee
or director or former employee or director of Acquirer, or under which Acquirer
has any liability. Such material plans (excluding any such plan that is a
"multiemployer plan," as defined in Section 3(37) of ERISA) are referred to
collectively herein as the "ACQUIRER EMPLOYEE PLANS."

      (b) Except as set forth in the Acquirer Disclosure Letter, each Acquirer
Employee Plan has been maintained in compliance with its terms and with the
requirements prescribed by any and all statutes, orders, rules and regulations
(including but not limited to ERISA and the Code) which are applicable to such
Plan, except where failure to so comply would not, individually or in the
aggregate, have a Material Adverse Effect on Acquirer.

      (c) Neither Acquirer nor any affiliate of Acquirer has incurred a
liability under Title IV of ERISA that has not been satisfied in full, and no
condition exists that presents a material risk to Acquirer or any affiliate of
Acquirer of incurring any such liability other than liability for premiums due
the Pension Benefit Guaranty Corporation (which premiums have been paid when
due).

      (d) All Acquirer Employee Plans that are intended to be qualified under
Section 401(a) of the Code have been the subject of determination, opinion,
notification or advisory letters from the IRS which Acquirer has made available
to the Company. Each such letter has the effect of stating that each such
Acquirer Employee Plan is qualified and is exempt from Federal income taxes
under Section 501(a) of the Code. The remedial amendment period with respect to
each such Acquirer Employee Plan has not expired for any amendment to any such
Acquirer Employee Plan that was made on or after the date of the application for
the determination, opinion, notification or advisory letter. No such
determination, opinion, notification or advisory letter has been revoked, nor
has any event occurred since the date of the most recent such letter that would
adversely affect its qualification, other than as set forth in the Acquirer
Disclosure Letter.

      (e) Except as set forth in the Acquirer Disclosure Letter, no director or
officer or other employee of Acquirer or any of its Subsidiaries will become
entitled to any retirement, severance or similar benefit or enhanced or
accelerated benefit (including any acceleration of vesting or lapse of
repurchase rights or obligations with respect to any employee stock option or
other benefit under any stock option plan or compensation plan or arrangement of
Acquirer) solely as a result of the transactions contemplated hereby.

      (f) Except as reflected in Acquirer SEC Documents filed prior to the date
hereof, no Acquirer Employee Plan provides post-retirement health and medical,
life or other insurance benefits for retired employees of Acquirer or any of its
Subsidiaries (other than benefit coverage mandated by applicable statute,
including benefits provided pursuant to COBRA).

      (g) Except as set forth in the Acquirer Disclosure Letter, there has been
no amendment to, written interpretation or announcement (whether or not written)
by Acquirer or any of its affiliates relating to, or change in employee
participation or coverage under, any Acquirer Employee Plan which would



                                       22
<PAGE>   27
increase materially the expense of maintaining such Acquirer Employee Plan above
the level of the expense incurred in respect thereof for the 12 months ended on
the Acquirer Balance Sheet Date.

      Section 4.15 Compliance with Laws. Neither Acquirer nor any of its
Subsidiaries is in violation of, or has since January 1, 1999 violated, any
applicable provisions of any laws, statutes, ordinances or regulations except
for any violations that, individually or in the aggregate, would not reasonably
be expected to have a Material Adverse Effect on Acquirer.

      Section 4.16 Finders' or Advisors' Fees. Except for Lehman Brothers Inc.,
there is no investment banker, broker, finder or other intermediary which has
been retained by or is authorized to act on behalf of Acquirer or any of its
Subsidiaries who might be entitled to any fee or commission in connection with
the transactions contemplated by this Agreement.

      Section 4.17 Environmental Matters. Except for such exceptions as,
individually or in the aggregate, have not had, and would not reasonably be
expected to have, a Material Adverse Effect on Acquirer, (i) no notice,
notification, demand, request for information, citation, summons, complaint or
order has been received by, and no investigation, action, claim, suit,
proceeding or review is pending or, to the knowledge of Acquirer or any of its
Subsidiaries, threatened by any Person against, Acquirer or any of its
Subsidiaries, and no penalty has been assessed against Acquirer or any of its
Subsidiaries, in each case, with respect to any matters relating to or arising
out of any Environmental Law; (ii) Acquirer and its Subsidiaries are and have
been in compliance with all Environmental Laws; and (iii) there are no
liabilities of or relating to Acquirer or any of its Subsidiaries relating to or
arising out of any Environmental Law of any kind whatsoever, whether accrued,
contingent, absolute, determined, determinable or otherwise, and there is no
existing condition, situation or set of circumstances which could reasonably be
expected to result in such a liability.

      Section 4.18 Labor Matters. There are no controversies pending or, to the
best knowledge of each of Acquirer and its respective Subsidiaries, threatened,
between Acquirer or any of its Subsidiaries and any of their respective
employees, which controversies have or could reasonably be expected to have a
Material Adverse Effect of the Acquirer. As of the date of this Agreement,
neither Acquirer nor any of its Subsidiaries is a party to any collective
bargaining agreement or other labor union contract applicable to persons
employed by Acquirer or its Subsidiaries nor does Acquirer or its Subsidiaries
know of any activities or proceedings of any labor union to organize any such
employees (i) as of the date of this Agreement and (ii) which, as of the Closing
Date, have or could reasonably be expected to have a Material Adverse Effect on
Acquirer and its Subsidiaries. As of the date of this Agreement, neither
Acquirer nor any of its Subsidiaries has any knowledge of any strikes,
slowdowns, work stoppages or lockouts, or threats thereof, by or with respect to
any employees of Acquirer or any of its Subsidiaries (x) as of the date of this
Agreement and (y) which, as of the Closing Date, have or could reasonably be
expected to have a Material Adverse Effect on Acquirer and its Subsidiaries.

      Section 4.19 Title to Property. Acquirer and each of its Subsidiaries has
good and marketable title to all of its material properties and assets, free and
clear of all Liens, except for liens for taxes not yet due and payable and such
liens or other imperfections of title and use restrictions, if any, as do not
materially detract from the value of or interfere with the present use of the
property affected thereby or which, individually or in the aggregate, would not
have a Material Adverse Effect on Acquirer.

      Section 4.20 Leaseholds. Neither Acquirer nor any of its Subsidiaries has
given or received notice of any material default under any material lease under
which Acquirer or any of its Subsidiaries is the lessee of real property (each
an "ACQUIRER LEASE" and collectively the "ACQUIRER LEASES") and, to the
knowledge of Acquirer, neither Acquirer nor any of its Subsidiaries nor any
other party thereto



                                       23
<PAGE>   28
is in default in any material respect under any of the Acquirer Leases. All of
the Acquirer Leases are in full force and effect, and are valid, binding and
enforceable in accordance with their terms, except (i) as limited by applicable
bankruptcy, insolvency, reorganization, moratorium and other laws of general
application affecting enforcement of creditors' or lessors' rights generally and
(ii) as limited by laws relating to the availability of specific performance,
injunctive relief or other equitable remedies. Except as set forth in the
Acquirer Disclosure Letter, neither Acquirer nor any of its Subsidiaries has
leased, subleased, licensed or assigned, as the case may be, all or any portion
of its leasehold interest under any Acquirer Lease to any person.

      Section 4.21 Management Payments. Other than as set forth in the Acquirer
Disclosure Letter, no employee or former employee of Acquirer will be entitled

any compensation that arises out of or are related to the consummation of the
Merger and the transactions contemplated thereby.

      Section 4.22 Intellectual Property. Acquirer or its Subsidiaries owns each
of the patents and patent applications referred to in the Acquirer SEC Documents
and, except as set forth in the Acquirer SEC Documents, (i) to the knowledge of
Acquirer, each of Acquirer and its Subsidiaries owns or possesses, or could
obtain ownership or possession of (on terms not materially adverse to the
consolidated financial position, stockholders' equity, or results of operations
of Acquirer and its Subsidiaries taken as a whole) adequate and enforceable
rights to use all other Intellectual Property necessary for the conduct of their
businesses, (ii) no claims are pending or, to the knowledge of Acquirer,
threatened that Acquirer or any Subsidiary is infringing on or otherwise
violating the rights of any Person with regard to any Intellectual Property
that, if the subject of an unfavorable decision, ruling or finding, could
reasonably be expected to (or, with respect to any pending patent litigation,
Acquirer does not believe will) have a Material Adverse Effect and Acquirer
knows of no basis therefor, and (iii) to the knowledge of Acquirer, no person is
infringing on or otherwise violating any right of Acquirer or any Subsidiary
with respect to any Intellectual Property owned by or licensed to Acquirer or
any Subsidiary. Except as set forth in the Acquirer SEC Documents, Acquirer has
received no notice of potential indemnity claims from customers based upon a
notice of infringement any such customer has received from a patent owner
relating to an assertion of infringement of a patent other than potential
indemnity claims that individually or in the aggregate would not reasonably be
expected to have a Material Adverse Effect. Acquirer's policy is to require that
its employees execute agreements assigning to Acquirer all rights such employees
otherwise would have in Intellectual Property developed by such employees while
in the employ of Acquirer.

      Section 4.23 Insurance. The insurance carried by Acquirer and its
Subsidiaries is in such types and amounts and covering such risks as are
consistent with customary practices and standards of companies engaged in
businesses and operations similar to those of Acquirer and its Subsidiaries.
Except as would not have a Material Adverse Effect on Acquirer, all such
insurance is in full force and effect and none of Acquirer nor any of its
Subsidiaries is in default thereunder. Except as would not have a Material
Adverse Effect on Acquirer, all claims thereunder have been filed in a due and
timely fashion. Except as would not have a Material Adverse Effect on Acquirer,
neither Acquirer nor any of its Subsidiaries has been notified in writing of a
refusal of any material insurance coverage relating to products liability
(including renewals of any such products liability coverage) by any insurance
carrier to which it has applied for insurance during the past three years.

      Section 4.24 Year 2000 Compliance. Except as would not reasonably be
expected to have a Material Adverse Effect on Acquirer, all of Acquirer's
Information Technology effectively addresses the Year 2000 Issues, and will not
cause an interruption in the ongoing operations of Acquirer's business on or
after January 1, 2000.

      Section 4.25 Opinion of Financial Advisor. Acquirer has received the
opinion of Lehman Brothers Inc. to the effect that, as of the date of such
opinion, the Exchange Ratio is fair from a financial point of view to Acquirer,

      Section 4.26 Tax Treatment. Neither Acquirer nor, to Acquirer's knowledge,
any of its affiliates has taken or agreed to take any action or is aware of any
fact or circumstance that would prevent the Merger from qualifying as a 368
Reorganization.

this Agreement or as expressly agreed to in writing by Acquirer, during the
period from the date of this Agreement to the earlier of the termination of this
Agreement in accordance with Article IX (the "TERMINATION DATE") and the
Effective Time, each of the Company and its Subsidiaries will conduct its
operations according to its ordinary course of business consistent with past
practice, and will use all commercially reasonable efforts to preserve intact
its business organization, to keep available the services of its officers and
employees and to maintain satisfactory relationships with suppliers,

bankers, attorneys, accountants, financial advisors, agents or other
representatives (collectively, "REPRESENTATIVES"), shall directly or indirectly,
initiate, solicit or otherwise induce any inquiries or the making of a Company
Acquisition Proposal (as defined below). The Company further agrees that neither
it nor any of its Subsidiaries nor any of its or its Subsidiaries' officers or

cause its Representatives not to, directly or indirectly, have any discussions
with or provide any confidential information or data to any Person relating to a

Acquisition Proposal, or otherwise facilitate any effort or attempt to make or
implement a Company Acquisition Proposal; provided, however, that nothing

judgment of its Board of Directors, failure so to disclose would be inconsistent
with its obligations under applicable law; (ii) negotiating with or furnishing

recommending such Company Acquisition Proposal to its stockholders, if and only
to the extent that, in the case of actions referred to in clause (ii) or clause
(iii), such Company Acquisition Proposal is a Superior Proposal (as defined
below) and Acquirer is given at least two business days' notice of the identity
of the third party and all material terms and conditions of the Superior
Proposal to respond to such Superior Proposal. The Company agrees that it will,
on the date hereof, immediately cease and cause to be terminated any existing
activities, discussions or negotiations with any Person conducted heretofore

a Company Acquisition Proposal; provided that the Board of Directors of the
Company shall not recommend that the stockholders of the Company tender their
shares in connection with a tender offer except to the extent the Board of
Directors of the Company determines in its good faith judgment that such a
recommendation is required to comply with the fiduciary duties of the Board of
Directors of the Company to stockholders under applicable law, after receiving
the advice of outside legal counsel.

      For purposes of this Agreement, "COMPANY ACQUISITION PROPOSAL" shall mean
any offer or proposal (other than an offer or proposal by Acquirer) relating to
any transaction or series of related transactions involving: (A) any purchase
from the Company or acquisition by any Person or "group" (as defined under
Section 13(d) of the Exchange Act and the rules and regulations thereunder) of
more than a five percent (5%) interest in the total outstanding voting
securities of the Company or any tender offer or exchange offer that if
consummated would result in any person or "group" (as defined under Section
13(d) of the Exchange Act and the rules and regulations thereunder) beneficially
owning five percent (5%) or more of the total outstanding voting securities of
the Company or any merger, consolidation, business combination or similar
transaction involving the Company; (B) any sale, lease (other than in the
ordinary course of business), exchange, transfer, license (other than in the

respect of the Company, an unsolicited, bona fide Company Acquisition Proposal
for or in respect of at least a majority of the outstanding Company Shares on
terms that the Board of Directors of the Company determines, in its good faith
judgment (based on consultation with its financial advisors) to be more
favorable to the Company's stockholders than the terms of the Merger, that is
not subject to a financing condition, and is from a Person that in the
reasonable judgment of the Company's Board of Directors (based on advice from a
nationally recognized investment bank) is financially capable of consummating
such proposal.

Directors of Acquirer to stockholders under applicable law, after receiving the
advice of outside legal counsel.

      For purposes of this Agreement, "ACQUIRER ACQUISITION PROPOSAL" shall mean

Directors (based on advice from a nationally recognized investment bank) is
financially capable of consummating such proposal.

      Section 6.3 Indemnification. (a) Acquirer shall indemnify, defend and hold
harmless the present and former officers, directors, employees and agents of the
Company and its Subsidiaries against all losses, claims, damages, expenses or
liabilities arising out of actions or omissions or alleged actions or omissions
occurring at or prior to the Effective Time to the same extent and on the same
terms and conditions (including with respect to advancement of expenses)
provided for in the Company's certificate of incorporation and by-laws and
agreements in effect at the date hereof (to the extent consistent with
applicable law). The certificate of incorporation and by-laws of the Surviving
Corporation shall contain the provisions with respect to indemnification and
exculpation from liability set forth in the Company's certificate of
incorporation and by-laws on the date of this Agreement, which provisions shall
not be amended, repealed or otherwise modified for a period of six years after
the Effective Time in any manner that would adversely affect the rights
thereunder of any person who, immediately prior to the Effective Time, was an
indemnified party under such provisions.

      (b) For a period of six years after the Effective Time, Acquirer shall
cause to be maintained in effect the current policies of directors' and
officers' liability insurance maintained by the Company (provided that Acquirer
may substitute therefor policies of at least the same coverage and amounts

claims arising from facts or events which occurred on or before the Effective
Time; provided, however, that Acquirer shall not be obligated to make annual
premium payments for such insurance to the extent such premiums exceed two
hundred percent (200%) of the premiums paid as of the date hereof by the Company
for such insurance.

      (c) The provisions of this Section 6.3 are intended to be for the benefit
of, and shall be enforceable by each indemnified party hereunder, his or her
heirs and his or her representatives.

the Company shall file with the SEC as soon as is reasonably practicable after

extent applicable, each of Acquirer and the Company will advise the other,
promptly after it receives notice thereof, of the time when the Form S-4 has

any stop order, the suspension of the qualification of the shares of Acquirer

for the purpose of voting upon (i) in the case of the Company, the adoption and

such effect) and in accordance with Sections 5.2 and 6.2, as the case may be, of
this Agreement, (i)(A) the Company will, through its Board of Directors,

not issue any such press release or make any such public statement prior to such
consultation, except as may be required by law.

      Section 7.6 Notification of Certain Matters. Each of the Company and
Acquirer shall give prompt notice to the other party of (i) any notice of, or
other communication relating to, a breach of this Agreement or event which, with
notice or lapse of time or both, would become a breach, received by it or any of
its Subsidiaries subsequent to the date of this Agreement and prior to the
Effective Time, under any contract to which it or any of its Subsidiaries is a
party or it, any of its Subsidiaries or any of its or their respective
properties is subject, which breach would be reasonably likely to have a
Material Adverse Effect on it, or (ii) any notice or other communication from
any third party alleging



                                       31
<PAGE>   36
that the consent of such third party is or may be required in connection with
the transactions contemplated by this Agreement.

      Section 7.7 Expenses. Except as set forth in Section 9.5, Acquirer, and
the Company, shall bear their respective expenses incurred in connection with
the Merger, including, without limitation, the preparation, execution and
performance of this Agreement and the transactions contemplated hereby, and all
fees and expenses of investment bankers, finders, brokers, agents,
representatives, counsel and accountants, except that expenses incurred in
printing, mailing and filing (including without limitation, SEC filing fees and
stock exchange listing application fees) Form S-4 and the Joint Proxy
Statement/Prospectus shall be shared equally by the Company and Acquirer.

become an Affiliate prior to the Effective Time. The Company shall cause each
person who is so identified as an Affiliate to deliver to Acquirer, no later

commercially reasonable efforts to confer and work together in good faith to
agree upon mutually acceptable employee benefit arrangements (and terminate
Company Employee Plans immediately prior to the Effective Time if appropriate)
so as to provide benefits to employees of the Company generally equivalent in
the aggregate to those provided to similarly situated employees of Acquirer. In
addition, the Company agrees that it and its Subsidiaries shall terminate any
and all group severance, separation, retention and salary continuation plans,
programs or arrangements (other than contractual agreements disclosed on the
Company Disclosure Letter) prior to the Effective Time. Years of service with
the Company or any of its Subsidiaries or predecessor organizations thereof (and
service otherwise credited by the Company or any of its Subsidiaries or
predecessor organizations thereof) prior to the Effective Time shall be credited
under the Acquirer Employee Plans listed under Items 3, 11 and 12 of Schedule
4.14(a) to the Acquirer Disclosure Letter to the same extent as service with
Acquirer is credited under such Acquirer Employee Plans (including for purposes
of eligibility, vesting and benefit accrual). Employees of the Company who
participate in an Acquirer Employee Plan listed under Items 3, 11 and 12 of
Schedule 4.14(a) to the Acquirer Disclosure Letter shall participate in such
Acquirer Employee Plan on terms no less favorable than those offered by Acquirer
to employees of Acquirer (including those provisions relating to the coverage of
dependents). Acquirer shall use its commercially reasonable efforts to cause any
and all pre-existing condition limitations, eligibility waiting periods and
evidence of insurability requirements under any group plans to be waived with
respect to Employees of the Company who participate in any Acquirer Employee
Plan listed under Items 3, 11 and 12 of Schedule 4.14(a) to the Acquirer
Disclosure Letter, and their eligible dependents, and shall provide each such
participant and dependent with credit for any co-payments and deductibles paid
prior to the Effective Time for purposes of satisfying any applicable
deductible, out-of-pocket, or similar requirements under all such Acquirer
Employee Plans in which such participants are eligible to participate after the
Effective Time. Notwithstanding any of the foregoing to the contrary, none of
the provisions contained herein shall operate to duplicate any benefit provided
to any employee of the Company or the funding of any such benefit.

      Section 7.10 Formation of Merger Subsidiary. As soon as practicable
following the execution of this Agreement, but no later than one week following
such date, Acquirer shall cause Merger Subsidiary to be formed in the State of
Delaware and to take all corporate action necessary to approve



                                       32
<PAGE>   37
and to become a party to this Agreement. Each of the parties hereto agrees that
upon formation of Merger Subsidiary it shall execute an amendment to this
Agreement and such other documents as may be necessary to cause Merger
Subsidiary to become a party to this Agreement.

      Section 9.5 Effect of Termination. (a) In the event of termination of this
Agreement pursuant to this Article IX, no party hereto (or any of its directors
or officers) shall have any liability or further obligation to any other party

hereof.

      (b) If

      9.3(d);

            (ii) Acquirer shall terminate this Agreement pursuant to Section

      conditions set forth in Section 8.2(a) would not have been satisfied as of
      such date and would not be reasonably capable of being satisfied;

      Agreement Acquirer consummates the transaction contemplated by such
      Acquirer Acquisition Proposal or enters into a definitive agreement with

then in any case as described in clause (i), (ii) or (iii) Acquirer shall pay to
the Company (by wire transfer of immediately available funds not later than the
date of termination of this Agreement or, in the case of clause (iii), the date
of such definitive agreement) an amount equal to $5,000,000. Except as provided
in Section 9.5(d), the fees provided for in this Section 9.5(c) are intended to
be liquidated damages and, as such, the sole and exclusive remedy for any and
all claims on any theory that might be asserted with respect to any of the
matters discussed in this Article IX, and no party hereto shall seek any
additional damages or remedies at law or in equity as a result or consequence of
any such matter. Acceptance by the Company of the payment referred to in the
foregoing sentence shall constitute conclusive evidence that this Agreement has
been validly terminated and upon acceptance of payment of such amount Acquirer
