                          AGREEMENT AND PLAN OF MERGER
 
     AGREEMENT AND PLAN OF MERGER (hereinafter called this "Agreement"), dated
as of July 27, 1997, among CHIPS AND TECHNOLOGIES, INC., a Delaware corporation
(the "Company"), INTEL CORPORATION, a Delaware corporation ("Parent"), and INTEL
ENTERPRISE CORPORATION, a Delaware corporation and a direct, wholly-owned
subsidiary of Parent ("Merger Sub"; the Company and Merger Sub sometimes being
hereinafter together referred to as the "Constituent Corporations").
 
                                    RECITALS
 
     WHEREAS, the respective Boards of Directors of each of Parent, Merger Sub
and the Company have approved the merger of Merger Sub with and into the Company
(the "Merger") and approved the Merger upon the terms and subject to the
conditions set forth in this Agreement; and
 
     WHEREAS, in furtherance thereof, it is proposed that Parent shall, within
five (5) Business Days after the public announcement hereof, commence a tender
offer (the "Offer") to acquire all of the outstanding shares of common stock,
par value $.01 per share, of the Company (the "Shares"), together with the
associated Rights (as defined in Section 4.1(a)), at a price of $17.50 per
Share, net to the seller in cash, less any required withholding taxes (such
amount, or any greater amount per share paid pursuant to the Offer, being
hereinafter referred to as the "Offer Price"), in accordance with the terms and
subject to the conditions provided herein; and
 
     WHEREAS, Parent, Merger Sub and the Company desire to make certain
representations, warranties, covenants and agreements in connection with the
Merger and also to prescribe various conditions to the Merger;
 
     NOW, THEREFORE, in consideration of the premises, and of the
representations, warranties, covenants and agreements contained herein, the
parties hereto agree as follows:
 
                                   ARTICLE I
 
                                   THE OFFER
 
     1.1.  The Offer.
 
          (a) Provided that this Agreement shall not have been terminated and
     subject to the terms hereof, as promptly as practicable, but in no event
     later than five (5) Business Days after the public announcement of the
     execution hereof by the parties, Parent shall commence (within the meaning
     of Rule 14d-2 under the Securities Exchange Act of 1934, as amended (the
     "Exchange Act")), the Offer for any and all of the Shares, at the Offer
     Price. The obligation of Parent to accept for payment and to pay for any
     Shares tendered shall be subject only to (i) the condition that at least a
     majority of Shares on a fully-diluted basis (including for purposes of such
     calculation all Shares issuable upon exercise of all vested and unvested
     stock options) be validly tendered (the "Minimum Condition"), and (ii) the
     other conditions set forth in Annex A. Parent expressly reserves the right
     to increase the Offer Price or to make any other changes in the terms and
     conditions of the Offer (provided that, unless previously approved by the
     Company in writing, no change may be made which (i) decreases the Offer
     Price, (ii) changes the form of consideration to be paid in the Offer,
     (iii) reduces the maximum number of Shares to be purchased in the Offer,
     (iv) imposes conditions to the Offer in addition to those set forth in
     Annex A, (v) amends the conditions set forth in Annex A to broaden the
     scope of such conditions, (vi) amends any other term of the Offer in a
     manner adverse to the holders of the Shares, (vii) extends the Offer except
     as provided in Section 1.1(b)), or (viii) amends the Minimum Condition. It
     is agreed that the conditions set forth in Annex A are for the sole benefit
     of Parent and may be waived by Parent, in whole or in part at any time and
     from time to time, in its sole discretion other than the Minimum Condition,
     as to which prior written Company approval is required. The failure by
     Parent at any time to exercise any of the foregoing rights shall not be
     deemed a waiver of any such right and each such right shall be deemed an
     ongoing right
<PAGE>   7
 
     which may be asserted at any time and from time to time. The Company agrees
     that no Shares held by the Company or any of its Subsidiaries (as defined
     in Section 9.2) will be tendered in the Offer.
 
          (b) Subject to the terms and conditions thereof, the Offer shall
     expire at midnight, New York City time, on the date that is twenty (20)
     Business Days after the date the Offer is commenced; provided, however,
     that without the consent of the Company's Board of Directors, Parent may
     (i) from time to time extend the Offer, if at the scheduled expiration date
     of the Offer any of the conditions to the Offer shall not have been
     satisfied or waived, until such time as such conditions are satisfied or
     waived; (ii) extend the Offer for any period required by any rule,
     regulation, interpretation or position of the Securities and Exchange
     Commission (the "SEC") or the staff thereof applicable to the Offer; or
     (iii) extend the Offer for any reason on one or more occasions for an
     aggregate period of not more than twenty (20) Business Days beyond the
     latest expiration date that would otherwise be permitted under clause (i)
     or (ii) of this sentence if on such expiration date there shall not have
     been tendered at least 90% of the outstanding Shares. Parent agrees that if
     all of the conditions to the Offer set forth on Annex A are not satisfied
     on any scheduled expiration date of the Offer then, provided that all such
     conditions are reasonably capable of being satisfied prior to October 31,
     1997, Parent shall extend the Offer from time to time until such conditions
     are satisfied or waived, provided that Parent shall not be required to
     extend the Offer beyond October 31, 1997. Subject to the terms and
     conditions of the Offer and this Agreement, Parent shall accept for
     payment, and pay for, all Shares validly tendered and not withdrawn
     pursuant to the Offer that Parent becomes obligated to accept for payment
     and pay for pursuant to the Offer, as promptly as practicable after the
     expiration of the Offer.
 
          (c) As soon as practicable on the date the Offer is commenced, Parent
     shall file with the SEC a Tender Offer Statement on Schedule 14D-1
     (together with all amendments and supplements thereto, and including all
     exhibits thereto, the "Schedule 14D-1") with respect to the Offer. The
     Schedule 14D-1 shall contain as an exhibit or incorporate by reference the
     Offer to Purchase (or portions thereof) and forms of the related letter of
     transmittal and summary advertisement. Parent and Merger Sub agree that the
     Schedule 14D-1, the Offer to Purchase and all amendments or supplements
     thereto (which together constitute the "Offer Documents") shall comply in
     all material respects with the Exchange Act and the rules and regulations
     thereunder and other applicable Laws (as defined in Section 5.1(i)). Parent
     and Merger Sub further agree that the Offer Documents, on the date first
     published, sent or given to the Company's stockholders, shall not contain
     any untrue statement of a material fact or omit to state any material fact
     required to be stated therein or necessary in order to make the statements
     therein, in light of the circumstances under which they were made, not
     misleading, except that no representation or warranty is made by Parent or
     Merger Sub with respect to information supplied by the Company or any of
     its stockholders specifically for inclusion or incorporation by reference
     in the Offer Documents. The Company agrees that the information provided by
     the Company for inclusion or incorporation by reference in the Offer
     Documents shall not contain any untrue statement of a material fact or omit
     to state any material fact required to be stated therein or necessary in
     order to make the statements therein, in light of the circumstances under
     which they were made, not misleading. Each of Parent, Merger Sub and the
     Company agrees promptly to correct any information provided by it for use
     in the Offer Documents if and to the extent that such information shall
     have become false or misleading in any material respect, and Parent and
     Merger Sub further agree to take all steps necessary to cause the Schedule
     14D-1 as so corrected to be filed with the SEC and the other Offer
     Documents as so corrected to be disseminated to the Company's stockholders,
     in each case as and to the extent required by applicable federal securities
     laws. The Company and its counsel shall be given reasonable opportunity to
     review and comment on the Offer Documents prior to the filing thereof with
     the SEC. Parent agrees to provide the Company and its counsel in writing
     with any comments Parent or its counsel may receive from the SEC or its
     staff with respect to the Offer Documents promptly after receipt of such
     comments.
 
     1.2.  Company Actions.
 
          (a) The Company hereby approves of and consents to the Offer and
     represents that its Board of Directors, at a meeting duly called and held,
     has, subject to the terms and conditions set forth herein, (i) after
     evaluating the Merger in accordance with all of the provisions of Article
     Ninth of the Company's
 
                                        2
<PAGE>   8
 
     certificate of incorporation, determined that this Agreement and the
     transactions contemplated hereby, including the Offer and the Merger, taken
     together, are at a price and on terms which are adequate and are otherwise
     in the best interests of the Company and its stockholders (other than
     Parent and its Affiliates), (ii) approved this Agreement and the
     transactions contemplated hereby, including the Offer and the Merger, in
     all respects and such approval constitutes approval of the Offer, this
     Agreement and the Merger for purposes of (x) Section 203 of the Delaware
     General Corporation Law (the "DGCL"), (y) similar provisions of any other
     similar state statutes that might be deemed applicable to the transactions
     contemplated hereby and (z) the Rights Agreement (as defined in Section
     5.1(b)), (iii) resolved to recommend that the stockholders of the Company
     accept the Offer, tender their Shares thereunder to Parent and approve and
     adopt this Agreement and the Merger, and (iv) in accordance with the
     applicable provisions of the Assumed Stock Option Plan (as defined in
     Section 2.4), approved the assumption of the Assumed Stock Option Plan by
     Parent as contemplated by Section 6.8(c) and the conversion of the options
     under the Assumed Stock Option Plan outstanding at the Effective Time of
     the Merger. The Company consents to the inclusion of such recommendation
     and approval in the Offer Documents. The Company also represents that its
     Board of Directors has reviewed the opinion of Hambrecht & Quist LLC,
     financial advisor to the Board of Directors (the "Financial Advisor"),
     that, as of July 27, 1997, the consideration to be received pursuant to
     this Agreement is fair to the stockholders of the Company (other than
     Parent and its Affiliates) from a financial point of view (the "Fairness
     Opinion"). The Company has been authorized by the Financial Advisor to
     permit, subject to the prior review and consent by the Financial Advisor
     (such consent not to be unreasonably withheld), the inclusion of the
     fairness opinion (or a reference thereto) in the Offer Documents, the
     Schedule 14D-9 and the Proxy Statement.
 
          (b) The Company shall file with the SEC, concurrently with the filing
     of the Schedule 14D-1, a Solicitation/Recommendation Statement on Schedule
     14D-9 (together with all amendments and supplements thereto, and including
     all exhibits thereto, the "Schedule 14D-9") containing the recommendations
     described in Section 1.2(a) and shall mail the Schedule 14D-9 to the
     stockholders of the Company promptly after the commencement of the Offer.
     The Company agrees that the Schedule 14D-9 shall comply in all material
     respects with the Exchange Act and the rules and regulations thereunder and
     other applicable Laws. The Company further agrees that Schedule 14D-9, on
     the date first published, sent or given to the Company's stockholders,
     shall not contain any untrue statement of a material fact or omit to state
     any material fact required to be stated therein or necessary in order to
     make the statements therein, in light of the circumstances under which they
     were made, not misleading, except that no representation or warranty is
     made by the Company with respect to information supplied by the Parent or
     Merger Sub specifically for inclusion or incorporation by reference in
     Schedule 14D-9. Each of the Company, Parent and Merger Sub agrees promptly
     to correct any information provided by it for use in the Schedule 14D-9 or
     the Offer Documents if and to the extent that such information shall have
     become false or misleading in any material respect, and the Company further
     agrees to take all steps necessary to cause the Schedule 14D-9 as so
     corrected to be filed with the SEC and be disseminated to the Company's
     stockholders, in each case as and to the extent required by applicable
     federal securities laws. Parent and its counsel shall be given reasonable
     opportunity to review and comment on the Schedule 14D-9 prior to the filing
     thereof with the SEC.
 
          (c) In connection with the Offer, the Company shall, or shall cause
     its transfer agent to, promptly furnish Parent with such information,
     including updated lists of the stockholders of the Company, mailing labels
     and updated lists of security positions, and such assistance as Parent or
     its agents may reasonably request in communicating the Offer to the record
     and beneficial holders of Shares. Subject to the requirements of applicable
     law, and except for such steps as are necessary to disseminate the Offer
     Documents and any other documents necessary to consummate the Merger,
     Parent and Sub and their agents shall hold in confidence the information
     contained in any such labels, listings and files, will use such information
     only in connection with the Offer and the Merger and, if this Agreement
     shall be terminated, will deliver, and will use their reasonable efforts to
     cause their agents to deliver, to the Company all copies and any extracts
     or summaries from such information then in their possession or control.

          (d) Solely in connection with the tender and purchase of Shares
     pursuant to the Offer and the consummation of the Merger, the Company
     hereby waives any and all rights of first refusal it may have with respect
     to Shares owned by, or issuable to, any Person, other than rights to
     repurchase unvested shares, if any, that may be held by Persons following
     exercise of employee stock options.
 
     1.3.  Boards of Directors and Committees; Section 14(f).
 
          (a) Promptly upon the purchase by Parent of Shares pursuant to the
     Offer and from time to time thereafter, if the Minimum Condition has been
     met, and subject to the second to last sentence of this Section 1.3(a),
     Parent shall be entitled to designate up to such number of directors,
     rounded up to the next whole number, on the Board of Directors of the
     Company as will give Parent representation on such Board equal to the
     product of the number of directors on such Board (giving effect to any
     increase in the number of directors pursuant to this Section 1.3) and the
     percentage that such number of Shares so purchased bears to the total
     number of outstanding Shares on a fully-diluted basis, and the Company
     shall use its best efforts to, upon request by Parent, promptly, at the
     Company's election, either increase the size of its Board of Directors
     (subject to the provisions of Article Sixth of the Company's certificate of
     incorporation) or secure the resignation of such number of directors as is
     necessary to enable Parent's designees to be elected to such Board and to
     cause Parent's designees to be so elected. At such times, and subject to
     the second to last sentence of this Section 1.3(a), the Company will use
     its best efforts to cause persons designated by Parent to constitute the
     same percentage as is on the Company's Board of Directors of (i) each
     committee of such Board (other than any committee of such Board established
     to take action under this Agreement), (ii) each Board of Directors of each
     Subsidiary of the Company and (iii) each committee of each such Board.
     Notwithstanding the foregoing, the Company shall use its best efforts to
     ensure that three of the members of its Board of Directors as of the date
     hereof ("Continuing Directors") shall remain members of such Board until
     the Effective Time (as defined in Section 2.3). In the event a Continuing
     Director resigns from the Company's Board of Directors, Parent, Merger Sub
     and the Company shall permit the remaining Continuing Director or Directors
     to appoint the resigning director's successor who shall be deemed to be a
     Continuing Director.
 
          (b) The Company's obligation to appoint designees to its Board of
     Directors shall be subject to Section 14(f) of the Exchange Act and Rule
     14f-1 promulgated thereunder. The Company shall promptly take all action
     required pursuant to such Section and Rule in order to fulfill its
     obligations under this Section 1.3 and shall include in the Schedule 14D-9
     such information with respect to the Company and its officers and directors
     as is required under such Section and Rule in order to fulfill its
     obligations under this Section 1.3. Parent will supply to the Company in
     writing and be solely responsible for any information with respect to
     itself and its nominees, officers, directors and Affiliates required by
     such Section and Rule.
 
          (c) Following the election or appointment of Parent's designees
     pursuant to this Section 1.3 and prior to the Effective Time, if there
     shall be any Continuing Directors, any amendment of this Agreement, any
     termination of this Agreement by the Company, any extension by the Company
     of the time for the performance of any of the obligations or other acts of
     Parent or any waiver of any of the Company's rights hereunder, will require
     the concurrence of a majority of such Continuing Directors.
 
                                   ARTICLE II
 
                      THE MERGER; CLOSING; EFFECTIVE TIME
 
     2.1.  The Merger.  Upon the terms and subject to the conditions set forth
in this Agreement, at the Effective Time (as defined in Section 2.3) Merger Sub
shall be merged with and into the Company and the separate corporate existence
of Merger Sub shall thereupon cease. The Company shall be the surviving
corporation in the Merger (sometimes hereinafter referred to as the "Surviving
Corporation") and shall continue to be governed by the laws of the State of
Delaware, and the separate corporate existence of the Company with all its
rights, privileges, immunities, powers and franchises shall continue unaffected
by the Merger, except as set forth in Article III. At the election of Parent, to
the extent that such action would not
 
                                        4
<PAGE>   10
 
cause a failure of a condition to the Offer of the Merger, the Merger may be
structured so that the Company shall be merged with and into Merger Sub with the
result that Merger Sub shall become the "Surviving Corporation." The Merger
shall have the effects specified in the DGCL. Parent, as the sole stockholder of
Merger Sub, hereby approves the Merger and this Agreement.
 
     2.2.  Closing.  The closing of the Merger (the "Closing") shall take place
(i) at the offices of Gibson, Dunn & Crutcher LLP, One Montgomery Street, San
Francisco, California at 9:00 am., Pacific time, on the first Business Day after
the day on which the last to be fulfilled or waived of the conditions set forth
in Article VII (other than those conditions that by their nature are to be
satisfied at the Closing, but subject to the fulfillment or waiver of those
conditions) shall be satisfied or waived in accordance with this Agreement or
(ii) at such other place and time and/or on such other date as the Company and
Parent may agree in writing (the "Closing Date").
 
     2.3.  Effective Time.  As soon as practicable following the Closing, the
Company and Parent will cause a Certificate of Merger (the "Delaware Certificate
of Merger") to be executed, acknowledged and filed with the Secretary of State
of Delaware as provided in Section 251 of the DGCL. The Merger shall become
effective at the time when the Delaware Certificate of Merger has been duly
filed with the Secretary of State of Delaware (the "Effective Time").
 
     2.4.  Options.  At the Effective Time, options under the Company's Amended
and Restated 1994 Stock Option Plan (the "Assumed Stock Option Plan") to
purchase Shares (each, a "Company Option"), which are then outstanding and
unexercised, shall cease to represent a right to acquire Shares and shall be
converted automatically into options to purchase shares of common stock, par
value $.001 per share, of Parent ("Parent Common Stock"), and Parent shall
assume each such Company Option subject to the terms of the Assumed Stock Option
Plan, in each case as heretofore amended or restated, as the case may be, and
the agreements evidencing grants thereunder; provided, however, that from and
after the Effective Time, (i) the number of shares of Parent Common Stock
purchasable upon exercise of such Company Option shall be equal to the number of
Shares that were purchasable under such Company Option immediately prior to the
Effective Time multiplied by the Exchange Ratio (as hereinafter defined), and
rounding to the nearest whole share, and (ii) the per share exercise price under
each such Company Option shall be adjusted by dividing the per share exercise
price of each such Company Option by the Exchange Ratio, and rounding down to
the nearest cent. The terms of each Company Option shall, in accordance with its
terms, be subject to further adjustment as appropriate to reflect any stock
split, stock dividend, recapitalization or other similar transaction with
respect to Parent Common Stock on or subsequent to the Effective Date.
Notwithstanding the foregoing, each Company Option which is intended to be an
"incentive stock option": (as defined in Section 422 of the Internal Revenue
Code of 1986, as amended, (the "Code")) shall be adjusted in accordance with the
requirements of Section 424 of the Code. Accordingly, with respect to any
incentive stock options, fractional shares shall be rounded down to the nearest
whole number of shares and the per share exercise price shall be rounded down to
the nearest cent. The Exchange Ratio is 0.197656.

                        CERTIFICATE OF INCORPORATION AND
               BY-LAWS OF THE SURVIVING CORPORATION; OFFICERS AND
                     DIRECTORS OF THE SURVIVING CORPORATION
 
     3.1.  Certificate of Incorporation.  The certificate of incorporation of
the Company as in effect immediately prior to the Effective Time shall be the
certificate of incorporation of the Surviving Corporation (the "Charter"), until
duly amended as provided therein or by applicable Law, except that Article
Fourth of the Charter shall be amended to read in its entirety as follows: "The
aggregate number of shares that the Corporation shall have the authority to
issue is 1,000 shares of Common Stock, par value $.01 per share."
 
     3.2.  By-Laws.  The by-laws of Merger Sub in effect at the Effective Time
shall be the by-laws of the Surviving Corporation (the "By-Laws"), until
thereafter amended as provided therein or by applicable Law.

     3.3.  Directors.  The directors of Merger Sub at the Effective Time shall,
from and after the Effective Time, be the directors of the Surviving Corporation
until their successors have been duly elected or appointed and qualified or
until their earlier death, resignation or removal in accordance with the Charter
and By-Laws.
 
     3.4.  Officers.  The officers of the Company at the Effective Time shall,
from and after the Effective Time, be the officers of the Surviving Corporation
until their successors have been duly elected or appointed and qualified or
until their earlier death, resignation or removal in accordance with the Charter
and By-Laws.
 
                                   ARTICLE IV
 
               EFFECT OF THE MERGER ON CAPITAL STOCK; EXCHANGE OF
                     CERTIFICATES FOR MERGER CONSIDERATION
 
     4.1.  Effect on Capital Stock.  At the Effective Time, as a result of the
Merger and without any action on the part of the holder of any Capital Stock (as
defined in Section 9.2) of the Company:
 
          (a) Merger Consideration.  Each Share issued and outstanding
     immediately prior to the Effective Time (other than Shares owned by Parent,
     Merger Sub or any other direct or indirect Subsidiary of Parent or Shares
     that are owned by the Company or any direct or indirect Subsidiary of the
     Company (collectively, the "Excluded Shares")) shall be converted into, and
     become exchangeable for the Offer Price, without interest (the "Merger
     Consideration"). Unless the context otherwise clearly requires, each
     reference in this Agreement to the Shares shall include the associated
     "Rights" as defined in and issued pursuant to the Rights Agreement (the
     "Rights"). At the Effective Time, all Shares shall no longer be outstanding
     and shall be canceled and retired and shall cease to exist, and each
     certificate (a "Certificate") formerly representing any of such Shares
     (other than Excluded Shares) shall thereinafter represent only the right to
     receive the Merger Consideration.
 
          (b) Cancellation of Excluded Shares.  Each Excluded Share issued and
     outstanding immediately prior to the Effective Time shall, by virtue of the
     Merger and without any action on the part of the holder thereof, cease to
     be outstanding, shall be canceled and retired without payment of any
     consideration therefor and shall cease to exist.
 
          (c) Merger Sub.  At the Effective Time, each share of Common Stock,
     par value $.01 per share, of Merger Sub issued and outstanding immediately
     prior to the Effective Time shall be converted into one share of Common
     Stock of the Surviving Corporation.
 
     4.2.  Exchange of Certificates for Payment.
 
          (a) Exchange Agent.  As of the Effective Time, Parent shall deposit,
     or shall cause to be deposited, with an exchange agent selected by Parent
     (the "Exchange Agent"), for the benefit of the holders of Shares, cash in
     U.S. dollars in an amount equal to the Merger Consideration multiplied by
     the aggregate outstanding Shares (other than Excluded Shares) to be paid
     pursuant to Section 4.1(a) in exchange for outstanding Shares upon due
     surrender of the Certificates (or affidavits of loss in lieu thereof)
     pursuant to the provisions of this Article IV (such aggregate cash amount
     when paid to the Exchange Agent being hereinafter referred to as the
     "Merger Fund").
 
          (b) Exchange Procedures.  Promptly after the Effective Time, the
     Surviving Corporation shall cause the Exchange Agent to mail to each holder
     of record of Shares (other than holders of Excluded Shares) (i) a letter of
     transmittal (which shall, among other matters, specify that delivery of the
     Certificates shall be effected, and risk of loss and title to the
     Certificates shall pass, only upon actual receipt of the Certificates (or
     affidavits of loss in lieu thereof) by the Exchange Agent) and (ii)
     instructions for use in effecting the surrender of the Certificates in
     exchange for the Merger Consideration due and payable to such holder. Upon
     surrender of a Certificate for cancellation to the Exchange Agent together
     with such letter of transmittal, duly executed, the holder of such
     Certificate shall be entitled to receive in exchange therefor a check in
     the amount (after giving effect to any required tax withholdings) of the
     Merger Consideration due and payable in respect of such holder's Shares and
     the Certificate so surrendered shall forthwith be canceled. No interest
     will be paid or accrued on any amount payable upon
 
                                        6
<PAGE>   12
 
     due surrender of the Certificates. All Merger Consideration paid upon
     surrender for exchange of Shares in accordance with the terms of this
     Agreement shall be deemed to have been paid in full satisfaction of all
     rights pertaining to such Shares. In the event of a transfer of ownership
     of Shares that is not registered in the transfer records of the Company, a
     check for the amount of cash to be paid upon due surrender of the
     Certificate may be delivered to such a transferee if the Certificate
     formerly representing such Shares is presented to the Exchange Agent,
     accompanied by all documents required by the Exchange Agent to evidence and
     effect such transfer and to evidence that any applicable stock transfer
     taxes have been paid.
 
          (c) Transfers.  After the Effective Time, there shall be no transfers
     on the stock transfer books of the Company of the Shares that were
     outstanding immediately prior to the Effective Time.
 
          (d) Termination of Merger Fund.  Any portion of the Merger Fund
     (including the proceeds of any investments thereof) that remains unclaimed
     by the stockholders of the Company for 180 days after the Effective Time
     shall be paid to Parent. Any stockholders of the Company who have not
     theretofore complied with this Article IV shall thereafter look only to
     Parent for payment of their Merger Consideration payable pursuant to
     Section 4.1 upon due surrender of their Certificates (or affidavits of loss
     in lieu thereof), in each case, without any interest thereon.
     Notwithstanding the foregoing, neither Parent, the Surviving Corporation,
     the Exchange Agent nor any other Person shall be liable to any former
     holder of Shares for any amount properly delivered to a public official
     pursuant to applicable abandoned property, escheat or similar laws. Any
     amounts remaining unclaimed by holders of Shares on the two (2) year
     anniversary of the Effective Time (or such earlier date immediately prior
     to such time as such amounts would otherwise escheat to or become property
     of any Governmental Entity (as defined in Section 5.1(d)) shall, to the
     extent permitted by applicable Law, become the property of Parent, free and
     clear of any claims or interest of any Person previously entitled thereto.
 
          (e) Return of Consideration.  Any portion of the Merger Fund
     representing Merger Consideration payable in respect of Dissenters' Shares
     (as defined in Section 4.3) for which appraisal rights have been perfected
     shall be returned to Parent, upon demand.
 
          (f) Lost, Stolen or Destroyed Certificates.  In the event 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 Parent, the posting by such
     Person of a bond in an amount determined by Parent as indemnity against any
     claim that may be made against it with respect to such Certificate, the
     Exchange Agent will issue in exchange for such lost, stolen or destroyed
     Certificate the Merger Consideration payable pursuant to Section 4.1 upon
     due surrender of the Certificate representing such Shares pursuant to this
     Agreement.
 
     4.3.  Dissenters' Shares.  Notwithstanding Section 4.1, Shares outstanding
immediately prior to the Effective Time and held by a holder who has not voted
in favor of the Merger or consented thereto in writing and who has demanded
appraisal for such Shares in accordance with the DGCL ("Dissenters' Shares")
shall not be converted into a right to receive the Merger Consideration, unless
such holder fails to perfect or withdraws or otherwise loses such holder's right
to appraisal. If after the Effective Time such holder fails to perfect or
withdraws or loses such holder's right to appraisal, such Dissenters' Shares
shall be treated as if they had been converted as of the Effective Time into a
right to receive the Merger Consideration. The Company shall give Parent prompt
notice of any demands received by the Company for appraisal of Dissenters'
Shares, and Parent shall have the right to participate in all negotiations and
proceedings with respect to such demands. The Company shall not, except with the
prior written consent of Parent, make any payment with respect to, or settle or
offer to settle, any such demands.

                         REPRESENTATIONS AND WARRANTIES
 
     5.1.  Representations and Warranties of the Company.  The Company hereby
represents and warrants to Parent and Merger Sub as follows:
 
          (a) Organization, Good Standing, Corporate Power and Qualification;
     Subsidiaries and Other Interests.
 
             (i) Each of the Company and its Subsidiaries (x) is a corporation
        duly organized, validly existing and in good standing under the laws of
        its respective jurisdiction of organization, (y) has all requisite
        corporate or similar power and authority to own and operate its
        properties and assets and to carry on its business as presently
        conducted and (z) is qualified to do business and is in good standing as
        a foreign corporation in each jurisdiction where the ownership or
        operation of its properties or conduct of its business requires such
        qualification, except where the failure to be so qualified or in good
        standing, individually or in the aggregate, has not had and is not
        reasonably likely to have a Company Material Adverse Effect (as defined
        in Section 9.2). The Company has made available to Parent a complete and
        correct copy of the Company's and its Subsidiaries' certificates of
        incorporation and by-laws (or comparable governing documents), each as
        amended to the date hereof. The Company's and its Subsidiaries'
        certificates of incorporation and by-laws (or comparable governing
        documents) made available are in full force and effect.
 
             (ii) Schedule 5.1(a) contains a correct and complete list of each
        of the Company's Subsidiaries, the jurisdiction where each of such
        Subsidiaries is organized and the percentage of outstanding Capital
        Stock of such Subsidiaries that is directly or indirectly owned by the
        Company. The Company or another Subsidiary of the Company owns its
        shares of the Capital Stock of each Subsidiary of the Company free and
        clear of all Liens except Permitted Liens (as defined in Section 9.2).
        Schedule 5.1(a) sets forth a true and complete list of each equity
        investment in an amount of $2,000,000 or more or which represents a 5%
        or greater ownership interest in the subject of such investment made by
        the Company or any of its Subsidiaries in any other Person other than
        the Company's Subsidiaries ("Other Interests"). The Other Interests are
        owned by the Company, by one or more of the Company's Subsidiaries or by
        the Company and one or more of its Subsidiaries, in each case free and
        clear of all Liens, except for Permitted Liens and Liens that may be
        created by any partnership or joint venture agreements for Other
        Interests.
 
          (b) Capital Structure.  The authorized Capital Stock of the Company
     consists of (i) one hundred million (100,000,000) Shares, of which
     22,003,195 were outstanding as of the close of business on July 27, 1997,
     and (ii) five million (5,000,000) shares of Preferred Stock, par value $.01
     per share (the "Preferred Shares"), none of which is outstanding. All of
     the outstanding Shares have been duly authorized and are validly issued,
     fully paid and nonassessable. The Company has no Preferred Shares reserved
     for issuance. Schedule 5.1(h) contains a correct and complete list as of
     July 27, 1997 of each outstanding purchase right or option (each a "Company
     Option") to purchase Shares, including all Company Options issued under the
     Company's Amended and Restated Employee Stock Purchase Plan, the Company's
     Amended and Restated 1994 Stock Option Plan and the Company's First Amended
     1988 Nonqualified Stock Option Plan for Outside Directors, in each case as
     amended to the date hereof (collectively, the "Stock Option Plans"),
     including the holder, date of grant, exercise price and number of Shares
     subject thereto. The Stock Option Plans are the only plans under which any
     Company Options are outstanding. As of July 27, 1997, other than (1) the
     3,983,598 Shares reserved for issuance upon exercise of outstanding Company
     Options and (2) Shares reserved for issuance pursuant to the Rights
     Agreement, dated as of August 23, 1989, between the Company and Bank of
     America, NT & SA, as Rights Agent (the "Rights Agreement"), there are no
     Shares reserved for issuance or any commitments for the Company to issue
     Shares. Each of the outstanding shares of Capital Stock or other securities
     of each of the Company's Subsidiaries directly or indirectly owned by the
     Company is duly authorized, validly issued, fully paid and nonassessable
     and owned by the Company or by a direct or indirect Subsidiary of the
     Company, free and clear of any limitation or restriction (including any
     restriction on the
 
                                        8
<PAGE>   14
 
     right to vote or sell the same except as may be provided as a matter of
     Law). Except for Company Options, there are no preemptive or other
     outstanding rights, options, warrants, conversion rights, stock
     appreciation rights, redemption rights, repurchase rights, agreements or
     commitments to issue or sell any shares of Capital Stock or other
     securities of the Company or any of its Subsidiaries or any securities or
     obligations convertible or exchangeable into or exercisable for, or giving
     any Person a right to subscribe for or acquire, any shares of Capital Stock
     or other securities of the Company or any of its Subsidiaries, and no
     securities or obligations evidencing such rights are authorized, issued or
     outstanding. The Company does not have outstanding any bonds, debentures,
     notes or other obligations the holders of which have the right to vote (or
     convertible into or exercisable for securities having the right to vote)
     with the stockholders of the Company on any matter ("Voting Debt"). If
     Parent takes the actions provided for in Section 6.8(c) hereof, after the
     Effective Time, the Surviving Corporation will have no obligation to issue,
     transfer or sell any shares of Capital Stock or other securities of the
     Surviving Corporation pursuant to the Stock Option Plans. The Shares
     constitute the only class of securities of the Company or any of its
     Subsidiaries registered or required to be registered under the Exchange
     Act.
 
        (c) Corporate Authority; Approval and Fairness.
 
             (i) The Company has all requisite corporate power and authority and
        has taken all corporate action necessary in order to execute, deliver
        and perform its obligations under this Agreement and to consummate,
        subject (if required by law) only to approval of this Agreement by the
        holders of a majority of the outstanding Shares (the "Company Requisite
        Vote"), the Merger. Assuming due execution and delivery by Parent and
        Merger Sub, this Agreement is a valid and binding agreement of the
        Company enforceable against the Company in accordance with its terms,
        except as such enforceability may be limited by applicable bankruptcy
        laws or creditors' rights generally or by general principles of equity.
 
             (ii) The Board of Directors of the Company has unanimously approved
        this Agreement and the Merger and the other transactions contemplated
        hereby including, without limitation, the Offer and the assumption
        referred to in Section 6.8(c), has received and reviewed the Fairness
        Opinion and duly taken all other actions described in Sections 1.2(a),
        5.1(j) and 5.1(p).
 
          (d) Governmental Filings; No Violations.
 
             (i) Other than the filings and/or notices (A) pursuant to Section
        1.2, (B) with the Delaware Secretary of State, (C) under the
        Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the
        "HSR Act") and the Exchange Act, (D) to comply with state securities or
        "blue sky" laws and (E) with the National Association of Securities
        Dealers (the "NASD"), no notices, reports or other filings are required
        to be made nor are any consents, registrations, approvals, permits or
        authorizations (collectively, "Government Consents") required to be
        obtained by the Company from any court or other governmental or
        regulatory authority, agency, commission, body or other governmental
        entity (a "Governmental Entity"), in connection with the execution and
        delivery of this Agreement by the Company and the consummation by the
        Company of the Merger and the other transactions contemplated hereby,
        except those that the failure to make or obtain are not, individually or
        in the aggregate, reasonably likely to have a Company Material Adverse
        Effect or prevent, materially delay or materially impair the ability of
        the Company to consummate the transactions contemplated by this
        Agreement.
 
             (ii) The execution, delivery and performance of this Agreement by
        the Company does not, and the consummation by the Company of the Merger
        and the other transactions contemplated hereby will not, constitute or
        result in (A) a breach or violation of or a default under, the
        certificate of incorporation or by-laws of the Company or the comparable
        governing instruments of any of its Subsidiaries, (B) a breach or
        violation of, or a default under, the acceleration of any obligations or
        the creation of any Lien on the assets of the Company or any of its
        Subsidiaries (with or without notice, lapse of time or both) pursuant
        to, any agreement, lease, contract, note, mortgage, indenture or other
        obligation (a "Contract") binding upon the Company or any of its
        Subsidiaries or any order, writ, injunction, decree of any court or any
        Law or governmental or non-governmental permit or
 
                                        9
<PAGE>   15
 
        license to which the Company or any of its Subsidiaries is subject or
        (C) any change in the rights or obligations of any party under any
        Contract, except, in the case of clause (B) or (C) above, for any
        breach, violation, default, acceleration, creation or change that,
        individually or in the aggregate, is not reasonably likely to have a
        Company Material Adverse Effect or prevent, materially delay or
        materially impair the ability of the Company to consummate the
        transactions contemplated by this Agreement. Except as set forth on
        Schedule 5.1(d), there are no Contracts of the Company or its
        Subsidiaries which are material to the Company and its Subsidiaries,
        taken as a whole, pursuant to which consents or waivers are or may be
        required prior to consummation of the Offer or the Merger and the other
        transactions contemplated by this Agreement.
 
          (e) Company Reports; Financial Statements.  The Company has made
     available to Parent each registration statement, report, proxy statement or
     information statement filed with the SEC by it since June 30, 1996 (the
     "Audit Date"), including the Company's Annual Report on Form 10-K for the
     year ended June 30, 1996 (the "Company 10-K") in the form (including
     exhibits, annexes and any amendments thereto) filed with the SEC
     (collectively, including any such reports filed subsequent to the date
     hereof, the "Company Reports"). As of their respective dates, the Company
     Reports complied, and any Company Reports filed with the SEC after the date
     hereof will comply, as to form in all material respects with the applicable
     requirements of the Exchange Act and the Securities Act of 1933, as amended
     (the "Securities Act"), and the Company Reports did not, and any Company
     Reports filed with the SEC after the date hereof will not, at the time of
     their filing, 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 made therein, in light of the circumstances in which they
     were made, not misleading. Each of the consolidated balance sheets included
     in or incorporated by reference into the Company Reports (including the
     related notes and schedules) fairly presents, or will fairly present, the
     consolidated financial position of the Company and its Subsidiaries as of
     its date and each of the consolidated statements of income and of changes
     in financial position included in or incorporated by reference into the
     Company Reports (including any related notes and schedules) fairly
     presents, or will fairly present, the results of operations, retained
     earnings and changes in financial position, as the case may be, of the
     Company and its Subsidiaries for the periods set forth therein (subject, in
     the case of unaudited statements, to notes and normal year-end audit
     adjustments that will not be material in amount or effect), in each case in
     accordance with United States generally accepted accounting principles
     ("GAAP") consistently applied during the periods involved, except as may be
     noted therein. The Company has heretofore made available or promptly will
     make available to Parent a complete and correct copy of all amendments or
     modifications which are required to be filed with the SEC but have not yet
     been filed with the SEC to the Company Reports, agreements, documents or
     other instruments which previously had been filed by the Company with the
     SEC pursuant to the Exchange Act. For purposes of this Agreement, "Balance
     Sheet" means the consolidated balance sheet of the Company as of June 30,
     1996 set forth in the Company 10-K. Except as set forth in Company Reports
     filed with the SEC prior to the date hereof or as incurred in the ordinary
     course of business since the date of the most recent financial statements
     included in the Company Reports, neither the Company nor any of its
     subsidiaries has any liabilities or obligations of any nature (whether
     accrued, absolute, contingent or otherwise) which would be required under
     GAAP to be set forth on a consolidated balance sheet of the Company and its
     subsidiaries taken as a whole and which individually or in the aggregate
     would have a Company Material Adverse Effect.
 
          (f) Absence of Certain Changes. Except as disclosed in Schedule 5.1(f)
     or in the Company Reports filed prior to the date hereof, since the Audit
     Date, the Company and its Subsidiaries have conducted their respective
     businesses in all material respects only in, and have not engaged in any
     material transaction other than according to, the ordinary and usual course
     of such businesses consistent with past practices, and there has not been
     any (i) change in the financial condition, properties, business or results
     of operations of the Company and its Subsidiaries, except for those changes
     that, individually or in the aggregate, have not had and are not reasonably
     likely to have a Company Material Adverse Effect; (ii) material damage,
     destruction or other casualty loss with respect to any material asset or
     property owned, leased or otherwise used by the Company or any of its
     Subsidiaries, not covered by insurance;
 
                                       10
<PAGE>   16
 
     (iii) declaration, setting aside or payment of any dividend or other
     distribution in respect of the Capital Stock of the Company or any of its
     Subsidiaries (other than wholly-owned Subsidiaries) or any repurchase,
     redemption or other acquisition by the Company or any of its Subsidiaries
     of any outstanding shares of Capital Stock or other securities of, or other
     ownership interests in, the Company or any of its Subsidiaries; (iv)
     amendment of any material term of any outstanding security of the Company
     or any of its Subsidiaries; (v) incurrence, assumption or guarantee by the
     Company or any of its Subsidiaries of any indebtedness for borrowed money
     other than in the ordinary course of business and in amounts and on terms
     consistent with past practices; (vi) creation or assumption by the Company
     or any of its Subsidiaries of any Lien (other than Permitted Liens) on any
     material asset other than in the ordinary course of business consistent
     with past practices; (vii) making of any loan, advance or capital
     contributions by the Company or any of its Subsidiaries to, or investment
     in, any Person other than (x) loans or advances to employees in connection
     with business-related travel (y) loans made to employees consistent with
     past practices which are not in the aggregate in excess of $250,000, and
     (z) loans, advances or capital contributions to or investments in
     wholly-owned Subsidiaries, and in each case made in the ordinary course of
     business consistent with past practices; (viii) transaction or commitment
     made, or any contract or agreement entered into, by the Company or any of
     its Subsidiaries relating to its assets or business (including the
     acquisition or disposition of any assets) or any relinquishment by the
     Company or any of its Subsidiaries of any Contract or other right, in
     either case, material to the Company and its Subsidiaries, taken as a
     whole, other than transactions and commitments in the ordinary course of
     business consistent with past practices and those contemplated by this
     Agreement; (ix) labor dispute, other than routine individual grievances, or
     any activity or proceeding by a labor union or representative thereof to
     organize any employees of the Company or any of its Subsidiaries, or any
     lockouts, strikes, slowdowns, work stoppages or threats thereof by or with
     respect to such employees; or (x) change by the Company or any of its
     Subsidiaries in accounting principles, practices or methods. Since the
     Audit Date, except as disclosed in the Company Reports filed prior to the
     date hereof or increases in the ordinary course of business consistent with
     past practices, there has not been any increase in the compensation payable
     or that could become payable by the Company or any of its Subsidiaries to
     (a) officers of the Company or any of its Subsidiaries or (b) any employee
     of the Company or any of its Subsidiaries whose annual cash compensation is
     $150,000 or more, or any amendment of any of the Compensation and Benefit
     Plans (as defined in Section 5.1(h)).
 
          (g) Litigation and Liabilities.  Except as disclosed in Schedule
     5.1(g) or in the Company Reports filed prior to the date hereof, and except
     for matters which, individually or in the aggregate, have not had and are
     not reasonably likely to have a Company Material Adverse Effect or prevent,
     delay or impair the ability of the Company to consummate the transactions
     contemplated by this Agreement, there are no (i) civil, criminal or
     administrative actions, suits, claims, hearings, investigations or
     proceedings pending or, to the knowledge of the Company, threatened against
     the Company or any of its Subsidiaries or (ii) obligations or liabilities,
     whether or not accrued, contingent or otherwise and whether or not required
     to be disclosed, including those relating to matters involving any
     Environmental Law (as defined in Section 5.1(k)) or any other facts or
     circumstances of which the Company has knowledge that are reasonably likely
     to result in any claims against, or material obligations or liabilities of,
     the Company or any of its Subsidiaries.
 
          (h) Employee Benefits.
 
             (i) For purposes of this Agreement, "Compensation and Benefit
        Plans" means, collectively, each bonus, deferred compensation, pension,
        retirement, profit-sharing, thrift, savings, employee stock ownership,
        stock bonus, stock purchase, restricted stock, stock option, employment,
        termination, severance, compensation, medical, health, or other plan,
        agreement, policy or arrangement, whether written or oral, that covers
        employees or directors of the Company or any of its Subsidiaries, or
        pursuant to which former employees or directors of the Company or any of
        its Subsidiaries are entitled to current or future benefits. The Company
        has made available to Parent copies of all "employee pension benefit
        plans" (as defined in Section 3(2) of the Employee Retirement Income
        Security Act of 1974, as amended ("ERISA")) (sometimes referred to
        herein as "Pension Plans"),
 
                                       11
<PAGE>   17
 
        "employee welfare benefit plans" (as defined in Section 3(1) of ERISA)
        and all other Compensation and Benefit Plans maintained, or contributed
        to, by the Company or of its subsidiaries or any person or entity that,
        together with the Company and its subsidiaries, is treated as a single
        employer under Section 414(b), (c), (m) or (o) of the Internal Revenue
        Code of 1986, as amended (the "Code") (the Company and each such other
        person or entity, a "Commonly Controlled Entity") for the benefit of any
        current employees, officers or directors of the Company or any of its
        subsidiaries. The Company has also made available to Parent true,
        complete and correct copies of (1) the most recent annual report on Form
        5500 filed with the Internal Revenue Service with respect to each
        Compensation and Benefit Plan (if any such report was required), (2) the
        most recent summary plan description for each Compensation and Benefit
        Plan for which such summary plan description is required and (3) each
        trust agreement and group annuity contract related to any Compensation
        and Benefit Plan. Except as would not have a material adverse effect on
        the Company, each Compensation and Benefit Plan has been administered in
        accordance with its terms. Except as would not have a Company Material
        Adverse Effect, each of its subsidiaries and all the Compensation and
        Benefit Plans are all in compliance with applicable provisions of ERISA
        and the Code.
 
             (ii) Except as would not have a Company Material Adverse Effect,
        all Pension Plans have been the subject of determination letters from
        the Internal Revenue Service to the effect that such Pension Plans are
        qualified and exempt from Federal income taxes under Sections 401(a) and
        501(a), respectively, of the Code, and no such determination letter has
        been revoked nor has any event occurred since the date of its most
        recent determination letter or application therefor that would adversely
        affect its qualification or materially increase its costs.
 
             (iii) Neither the Company, nor any of its Subsidiaries, nor any
        Commonly Controlled Entity has maintained, contributed or been obligated
        to contribute to any Benefit Plan that is subject to Title IV of ERISA.
 
             (iv) Schedule 5.1(h) lists all outstanding Stock Options as of July
        27, 1997, showing for each such option: (1) the number of shares
        issuable, (2) the number of vested shares, (3) the date of expiration
        and (4) the exercise price.
 
             (v) All contributions required to be made under the terms of any
        Compensation and Benefit Plan as of the date hereof have been timely
        made.
 
             (vi) Except as provided by this Agreement or in Schedule 5.1(h), no
        employee 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 as a result of the transactions contemplated by this Agreement.
 
             (vii) All Compensation and Benefit Plans covering current or former
        non-U.S. employees of the Company or any of its Subsidiaries comply in
        all material respects with applicable local Laws. The Company and its
        Subsidiaries have no unfunded liabilities with respect to any Pension
        Plan that covers such non-U.S. employees.
 
             (viii) Each Compensation and Benefit Plan complies in all material
        respects with all applicable requirements of (i) the Age Discrimination
        in Employment Act of 1967, as amended, and the regulations thereunder
        and (ii) Title VII of the Civil Rights Act of 1964, as amended, and the
        regulations thereunder and all other applicable laws. All amendments and
        actions required to bring each of the Employee Benefit Plans into
        conformity with all of the applicable provisions of ERISA and other
        applicable laws have been made or taken except to the extent that such
        amendments or actions are not required by law to be made or taken until
        a date after the Closing Date and are disclosed on Schedule 5.1(h).
 
             (ix) Each group medical plan sponsored by the Company materially
        complies with the health care continuation provisions of COBRA and (ii)
        the Medicare Secondary Payor Provisions of Section 1826 (b) of the
        Social Security Act, and the regulations promulgated thereunder.

          (i) Compliance with Laws. Except as set forth in the Company Reports
     filed prior to the date hereof, the businesses of each of the Company and
     its Subsidiaries have not been, and are not being, conducted in violation
     of any law, ordinance, regulation, judgment, order, injunction, decree,
     arbitration award, license or permit of any Governmental Entity
     (collectively, "Laws"), except for violations or possible violations that,
     individually or in the aggregate, have not had and are not reasonably
     likely to have a Company Material Adverse Effect or prevent, materially
     delay or materially impair the ability of the Company to consummate the
     transactions contemplated by this Agreement. Except as set forth in the
     Company Reports filed prior to the date hereof, no investigation or review
     by any Governmental Entity with respect to the Company or any of its
     Subsidiaries is pending or, to the knowledge of the Company, threatened,
     nor has any Governmental Entity indicated an intention to conduct the same,
     except for those the outcome of which are not, individually or in the
     aggregate, reasonably likely to have a Company Material Adverse Effect or
     prevent, materially delay or materially impair the ability of the Company
     to consummate the transactions contemplated by this Agreement.
 
          (j) Takeover Statutes. No "fair price," "moratorium," "control share
     acquisition" or other similar anti-takeover statute or regulation (each a
     "Takeover Statute") is applicable to the Company, the Shares, the Offer,
     the Merger or any of the other transactions contemplated by this Agreement.
     The Board of Directors of the Company has approved the Offer, the Merger
     and this Agreement, and such approval is sufficient to render inapplicable
     to the Offer, the Merger, this Agreement, and the transactions contemplated
     by this Agreement the provisions of Section 203 of DGCL to the extent, if
     any, such Section is applicable to the Offer, the Merger, this Agreement
     and the transactions contemplated by this Agreement.
 
        (k) Environmental Matters.
 
             (i) The term "Environmental Laws" means any Federal, state, local
        or foreign statute, treaty, ordinance, rule, regulation, policy, permit,
        consent, approval, license, judgment, order, decree or injunction
        relating to: (A) Releases (as defined in 42 U.S.C. sec. 9601(22) and
        California Health and Safety Code sec. 25501(r)) or threatened Releases
        of Hazardous Material (as hereinafter defined) into the environment, (B)
        the generation, treatment, storage, presence disposal, use, handling,
        manufacturing, transportation or shipment of Hazardous Material, (C) the
        health or safety of employees in the workplace environment, (D) natural
        resources, or (E) the environment, and includes all "Environmental Laws"
        as they are defined in any indemnification provision in any contract,
        lease, or agreement to which Company is a party. The term "Hazardous
        Material" means (1) hazardous substances (as defined in 42 U.S.C. sec.
        9601(14)) and California Health and Safety Code sec. 25501(o), including
        "hazardous waste" as defined in California Health and Safety Code sec.
        25501(p), (2) petroleum, including crude oil and any fractions thereof,
        (3) natural gas, synthetic gas and any mixtures thereof, (4) asbestos
        and/or asbestos containing materials, (5) PCBs or materials containing
        PCBs and (6) any material regulated as a medical waste or infectious
        waste but excludes commonly available office and janitorial supplies,
        (7) lead containing paint, (8) radioactive materials, and (9) "Hazardous
        Substance" or "Hazardous Material" as those terms are defined in any
        indemnification provision in any contract, lease, or agreement to which
        the Company is a party.
 
             (ii) During the period of ownership or operation by the Company and
        its Subsidiaries of any of their current or previously owned or leased
        properties, there have been no Releases of Hazardous Material by the
        Company or any of its Subsidiaries in, on, under or affecting such
        properties or any surrounding site, and neither the Company nor any of
        its Subsidiaries has disposed of any Hazardous Material in a manner that
        has led, or could reasonably be anticipated to lead to a Release, except
        in each case for those which individually or in the aggregate would not
        have a Company Material Adverse Effect, and except as disclosed in the
        Company Reports. Except as set forth on Schedule 5.1(k), to the
        Company's knowledge there have been no Releases of Hazardous Material by
        the Company or any of its Subsidiaries in, on, under or affecting such
        properties or any surrounding site at times outside of such periods of
        ownership, operation, or lease or by any other party except in each case
        for those which individually on in the aggregate would not have a
        Company Material Adverse Effect. The Company and its Subsidiaries have
        not received any written notice of, or entered into
 
                                       13
<PAGE>   19
 
        any order, settlement or decree relating to: (A) any violation of any
        Environmental Laws or the institution or pendency of any suit, action,
        claim, proceeding or investigation by any Governmental Entity or any
        third party in connection with any alleged violation of Environmental
        Laws, (B) the response to or remediation of Hazardous Material at or
        arising from any of the Company's properties or any Subsidiary's
        properties. To the Company's knowledge there have been no violations of
        any Environmental Laws which violations individually or in the aggregate
        would have a Company Material Adverse Effect.
 
        (l) Intellectual Property.
 
             (i) The Company and its subsidiaries own, or are validly licensed
        or otherwise have the right to use all (i) foreign and United States
        federal and state patents, trademarks, trade names, service marks and
        copyright registrations, (ii) foreign and United States federal and

        Entity and (vi) inventions, concepts, designs, improvements, original
        works of authorship, computer programs, know-how, research and
        development, techniques, modifications to existing copyrightable works
        of authorship, data and other proprietary and intellectual property
        rights (whether or not patentable or subject to copyright, mask work or
        trade secret protection), in each case which are material to the conduct
        of the business of the Company and its Subsidiaries (collectively, the
        "Intellectual Property Rights"). There are no Liens other than Permitted
        Liens on the Intellectual Property Rights. There are no outstanding and,
        to the Company's knowledge, no threatened disputes or disagreements with
        respect to any Contract in respect of the Intellectual Property Rights.
 
             (ii) Neither the Company nor any of its Subsidiaries is, nor has it
        during the three (3) years preceding the date of this Agreement been, a
        party to any litigation or arbitral or other proceeding, nor, to the
        knowledge of the Company, is any such proceeding threatened as to which
        there is a reasonable possibility of a determination adverse to the
        Company or one of its Subsidiaries, that involved a claim of
        infringement by the Company or one of its Subsidiaries or any other
        Person (including any Governmental Entity) of any Intellectual Property
        Right. No Intellectual Property Right is subject to any outstanding
        order, judgment, decree, stipulation or agreement restricting the use
        thereof by the Company or any of its Subsidiaries or, in the case of any
        Intellectual Property Right owned by the Company or its Subsidiaries
        licensed to others, restricting the sale, transfer, assignment or
        licensing thereof by the Company or any of its Subsidiaries to any other
        Person. Except as set forth on Schedule 5.1(ii), the Company has no
        knowledge that would cause it to believe that its or any Subsidiary's
        use of any Intellectual Property Right conflicts with, infringes upon or
        violates any patent, patent license, trademark, tradename, copyright,
        service mark, brand mark or brand name, or any trade secret of any
        Person.
 
             (iii) Schedule 5.1(l) (iii) sets forth a complete list of (a) any
        material contracts related to the Intellectual Property Rights and (b)
        all documents which license or otherwise convey any of the Intellectual
        Property Rights owned by the Company or any of its Subsidiaries to a
        third party.
 
             (iv) All employees and independent contractors of the Company or
        any of its Subsidiaries involved with the development of graphics and
        video controllers for portable computers, desktop PC motherboard
        products and other products and computer software in connection
        therewith (collectively, "Products") for the Company or any of its
        Subsidiaries have executed written agreements with the Company or
        applicable Subsidiary that assign to the Company or such Subsidiary all
        rights to any Intellectual Property Rights and that otherwise
        appropriately protect the Intellectual Property Assets.
 
          (m) Taxes. Except as set forth on Schedule 5.1(m), (i) the Company and
     its Subsidiaries have timely filed or will timely file all returns and
     reports required to be filed by them with any taxing authority with respect
     to Taxes for any period ending on or before the date hereof, taking into
     account any
 
                                       14
<PAGE>   20
 
     extension of time to file granted to or obtained on behalf of the Company
     or any of its Subsidiaries; (ii) all Taxes shown to be payable on such
     returns or reports that are due prior to the date hereof have been timely
     paid; (iii) as of the date hereof, no deficiency for any amount of Tax has
     been asserted or assessed or, to the Company's knowledge, has been
     threatened or is likely to be assessed by a taxing authority against the
     Company or any of its Subsidiaries other than deficiencies as to which
     adequate reserves have been provided for in the Company's consolidated
     financial statements; and (iv) the Company has provided in accordance with
     GAAP adequate reserves in its consolidated financial statements for any
     Taxes that have not been paid, whether or not shown as being due on any
     returns. For purposes of this Agreement, "Taxes" means any and all taxes,
     fees, levies, duties, tariffs, imposts and other charges of any kind
     (together with any and all interest, penalties, additions to tax and
     additional amounts imposed with respect thereto) imposed by any
     Governmental Entity or other taxing authority, including taxes or other
     charges on or with respect to income, franchises, windfall or other
     profits, gross receipts, property, sales, use, Capital Stock, payroll,
     employment, social security, workers' compensation, unemployment
     compensation, or net worth; taxes or other charges in the nature of excise,
     withholding, ad valorem, stamp, transfer, value added or gains taxes;
     license, registration and documentation fees; and customers' duties,
     tariffs and similar charges. Neither the Company nor any of its
     Subsidiaries is subject to any Tax sharing agreement. No payments to be
     made to any of the employees of the Company or any of its Subsidiaries
     will, as a direct or indirect result of the Offer or the consummation of
     the Merger, be subject to the deduction limitations of Section 280G of the
     Code.
 
          (n) Labor Matters.  Neither the Company nor any of its Subsidiaries is
     a party to or otherwise bound by any collective bargaining agreement,
     contract or other agreement or understanding with a labor union or labor
     organization, nor is the Company or any of its Subsidiaries the subject of
     any proceeding asserting that the Company or any of its Subsidiaries has
     committed an unfair labor practice or is seeking to compel it to bargain
     with any labor union or labor organization, nor is there pending or, to the
     knowledge of the Company, threatened, any labor strike, dispute, walkout,
     work stoppage, slow-down or lockout involving the Company or any of its
     Subsidiaries.
 
          (o) Insurance.  The Company maintains insurance policies (the
     "Insurance Policies") against all risks of a character and in such amounts
     as are usually insured against by similarly situated companies in the same
     or similar businesses. Each Insurance Policy is in full force and effect
     and is valid, outstanding and enforceable, and all premiums due thereon
     have been paid in full. None of the Insurance Policies will terminate or
     lapse (or be affected in any other materially adverse manner) by reason of
     the transactions contemplated by this Agreement. The Company and its
     Subsidiaries have complied in all material respects with the provisions of
     each Insurance Policy under which it is the insured party. No insurer under
     any Insurance Policy has canceled or generally disclaimed liability under
     any such policy or, to the Company's knowledge, indicated any intent to do
     so or not to renew any such policy. All material claims under the Insurance
     Policies have been filed in a timely fashion.
 
          (p) Rights Agreement.  The Company has taken all necessary action to
     ensure that neither the entering into of this Agreement, the making of the
     Offer nor the consummation of the Offer or the Merger will cause the Rights
     to become exercisable, cause Parent or Merger Sub to become an "Acquiring
     Person" (as defined in the Rights Agreement), or cause there to occur a
     "Distribution Date" or a "Section 11(a)(ii) Event" (each as defined in the
     Rights Agreement).
 
          (q) Brokers and Finders.  Neither the Company nor any of its
     Subsidiaries, officers, directors, or employees or other Affiliates has
     employed any broker or finder or incurred any liability for any brokerage
     fees, commissions or finders' fees in connection with the Offer, the Merger
     or the other transactions contemplated by this Agreement, except that the
     Company has employed the Financial Advisor, the arrangements with which
     have been disclosed to Parent prior to the date hereof.
 
          (r) Certain Business Practices.  Neither the Company, any of its
     Subsidiaries nor any directors, officers, agents or employees of the
     Company or any of its Subsidiaries has (i) used any funds for unlawful
     contributions, gifts, entertainment or other unlawful expenses related to
     political activity; (ii) made any unlawful payment to foreign or domestic
     government officials or employees or to foreign or
 
                                       15
<PAGE>   21
 
     domestic political parties or campaigns or violated any provision of the
     Foreign Corrupt Practices Act of 1977, as amended; or (iii) made any other
     payment prohibited by applicable Law.
 
          (s) Product Warranties.  Schedule 5.1(s) sets forth complete and
     accurate copies of the written, and descriptions of all oral, warranties
     and guaranties by the Company or any of its Subsidiaries currently in
     effect with respect to the Products. There have not been any material
     deviations from such warranties and guaranties, and none of the Company's
     or any of its Subsidiaries' salesmen, employees, distributors and agents is
     authorized to undertake obligations to any customer or to other third
     parties in excess of such warranties or guaranties.
 
          (t) Suppliers and Customers.  The documents and information supplied
     by the Company to Parent, Merger Sub or any of their representatives in
     connection with this Agreement with respect to relationships and volumes of
     business done with significant suppliers and customers was accurate in all
     material respects.
 
          (u) Backlog Information.  None of the documents or information
     delivered to Parent, Merger Sub or any of their respective counsel,
     accountants and other agents and representatives in connection with backlog
     and billing contains any untrue statement of a material fact or omits to
     state a material fact necessary in order to make the statements contained
     therein not misleading.
 
     5.2.  Representations and Warranties of Parent and Merger Sub.  Parent and
Merger Sub each hereby represents and warrants to the Company as follows:
 
          (a) Organization, Good Standing and Qualification.  Each of Parent and
     Merger Sub (i) is a corporation duly organized, validly existing and in
     good standing under the laws of the State of Delaware, (ii) has all
     requisite corporate or similar power and authority to own and operate its
     properties and assets and to carry on its business as presently conducted
     and (iii) is qualified to do business and is in good standing as a foreign
     corporation in each jurisdiction where the ownership or operation of its
     properties or conduct of its business requires such qualification, except
     where the failure to be so qualified or in such good standing, when taken
     together with all other such failures, has not had and is not reasonably
     likely to have a Parent Material Adverse Effect (as defined in Section
     9.2). Parent has made available to the Company a complete and correct copy
     of Parent's certificate or incorporation and by-laws, as amended to the
     date hereof. Parent's certificate of incorporation and by-laws so delivered
     are in full force and effect.
 
          (b) Ownership of Merger Sub.  All of the issued and outstanding
     Capital Stock of Merger Sub is, and at the Effective Time will be, owned by
     Parent, and there are no (i) other outstanding shares of Capital Stock or
     other voting securities of Merger Sub, (ii) securities of Merger Sub
     convertible into or exchangeable for shares of Capital Stock or other
     voting securities of Merger Sub or (iii) options or other rights to acquire
     from Merger Sub, and no obligations of Merger Sub to issue, any Capital
     Stock, other voting securities or securities convertible into or
     exchangeable for Capital Stock or other voting securities of Merger Sub.
     Merger Sub was formed solely for the purpose of engaging in the
     transactions contemplated hereby, has engaged in no other business
     activities and has conducted its operations only as contemplated hereby.
 
          (c) Corporate Authority.  Each of Parent and Merger Sub has all
     requisite corporate power and authority and has taken all corporate action
     necessary in order to execute, deliver and perform its obligations under
     this Agreement and to consummate the Offer and the Merger. Assuming due
     execution and delivery by the Company, this Agreement is a valid and
     binding agreement of Parent and Merger Sub, enforceable against each of
     them in accordance with its terms, except as such enforceability may be
     limited by applicable bankruptcy laws or creditors' rights generally or by
     general principles of equity.
 
          (d) Governmental Filings; No Violations.
 
             (i) Other than the filings and/or notices (A) pursuant to Section
        1.2, (B) under the HSR Act and the Exchange Act, (C) to comply with
        state securities or "blue sky" laws, and (D) required to be made with
        the NASD, no notices, reports or other filings are required to be made
        by Parent or Merger Sub with, nor are any Government Consents required
        to be obtained by Parent or Merger
 
                                       16

        Sub from, any Governmental Entity, in connection with the execution and
        delivery of this Agreement by Parent and Merger Sub, the Offer and the
        consummation by Parent and Merger Sub of the Merger and the other
        transactions contemplated hereby, except those that the failure to make
        or obtain are not, individually or in the aggregate, reasonably likely
        to have a Parent Material Adverse Effect or prevent, materially delay or
        materially impair the ability of the Parent or Merger Sub to consummate
        the transactions contemplated by this Agreement.
 
             (ii) The execution, delivery and performance of this Agreement by
        Parent and Merger Sub do not, and the consummation by Parent and Merger
        Sub of the Merger and the other transactions contemplated hereby will
        not, constitute or result in (A) a breach or violation of, or a default
        under, the certificate or by-laws of Parent or Merger Sub, (B) a breach
        or violation of, or a default under, the acceleration of or the creation
        of a Lien, on the assets of Parent or any of its Subsidiaries (with or
        without notice, lapse of time or both) pursuant to, any Contract binding
        upon Parent or any of its Subsidiaries or any Law to which Parent or any
        of its Subsidiaries is subject or (C) any change in the rights or
        obligations of any party under any such Contract, except, in the case of
        clause (B) or (C) above, for any breach, violation, default,
        acceleration, creation or change that, individually or in the aggregate,
        is not reasonably likely to have a Parent Material Adverse Effect or
        prevent, materially delay or materially impair the ability of the Parent
        or Merger Sub to consummate the transactions contemplated by this
        Agreement.
 
          (e) Brokers and Finders.  Neither Parent nor Merger Sub, nor any of
     their respective officers, directors, employees or other Affiliates, has
     employed any broker or finder or incurred any liability for any brokerage
     fees, commissions or finders' fees in connection with the Offer, the Merger
     or the other transactions contemplated by this Agreement.
 
          (f) Financing.  At the expiration of the Offer and at the Effective
     Time, Parent and Merger Sub will have available all the funds necessary for
     the acquisition of all Shares pursuant to the Offer and to perform their
     respective obligations under this Agreement, including without limitation
     payment in full for all Shares validly tendered or outstanding as of the
     Effective Time.

                                   COVENANTS
 
     6.1.  Interim Operations.  The Company covenants and agrees as to itself

     6.2.  Third Party Acquisitions.
 
          (a) The Company agrees that neither it nor any of its Subsidiaries nor
     any of its or its Subsidiaries' employees or directors shall, and it shall
     direct and use its best efforts to cause its and its Subsidiaries' agents
     and representatives (including the Financial Advisor or any other
     investment banker and any attorney or accountant retained by it or any of
     its Subsidiaries (collectively, "Company Advisors")) not to, directly or
     indirectly, initiate, solicit, encourage or otherwise facilitate any
     inquiries in respect of, or the making of any proposal for, a Third Party
     Acquisition (as defined in Section 6.2(b)). The Company further agrees that
     neither it nor any of its Subsidiaries nor any of its or its Subsidiaries'
     employees or directors shall, and it shall direct and use its best efforts
     to cause all Company Advisors not to, directly or indirectly, engage in any
     negotiations concerning, or provide any confidential information or data
     to, or have any discussions with, any Third Party (as defined in Section
     6.2(b)) relating to the proposal of a Third Party Acquisition, or otherwise
     facilitate any effort or attempt to make or implement a Third Party
     Acquisition; provided, however, that if at any time prior to the acceptance
     for payment of Shares pursuant to the Offer, the Board of Directors of the
     Company determines in good faith, after consultation with outside counsel,
     that it is necessary to do so in order to comply with its fiduciary duties
     to the Company's stockholders under applicable law, the Company may, in
     response to an inquiry, proposal or offer for a Third Party Acquisition
     which was not solicited subsequent to the date hereof, (x) furnish only
     such information with respect to the Company to any such person pursuant to
     a customary confidentiality agreement as was delivered to Parent prior to
     the execution of this Agreement and (y) participate in the discussions and
     negotiations regarding such inquiry, proposal or offer; and further
     provided, that nothing contained in this Agreement shall prevent the
     Company or its Board of Directors from complying with Rules 14d-9 and 14e-2
     promulgated under the Exchange Act with regard to any proposed Third Party
     Acquisition. The Company shall immediately cease and cause to be terminated
     any existing activities, discussions or negotiations with any Third Parties
     conducted heretofore with respect to any of the foregoing. The Company
     shall take the necessary steps to promptly inform all Company Advisors of
     the obligations undertaken in this Section 6.2(a). The Company agrees to
     notify Parent promptly if (i) any inquiries relating to or proposals for a
     Third Party Acquisition are received by the Company, any of its
     Subsidiaries or any of the Company Advisors, (ii) any confidential or other
     non-public information about the Company or any of its Subsidiaries is
     requested from the Company, any of its Subsidiaries or any of the Company
     Advisors, or (iii) any negotiations or discussions in connection with a
     possible Third Party Acquisition are sought to be initiated or continued
     with the Company, any of its Subsidiaries or any of the Company Advisors
     indicating, in connection with such notice, the principal terms and
     conditions of any proposals or offers, and thereafter shall keep Parent
     informed in writing, on a reasonably current basis, on the status and terms
     of any such proposals or offers and the status of any such negotiations or
     discussions. The Company also agrees promptly to request each Person that
     has heretofore executed a confidentiality agreement in connection with its
     consideration of acquiring the Company or any of its Subsidiaries, if any,
     to return all confidential information heretofore furnished to such Person
     by or on half of the Company or any of its Subsidiaries.
 
          (b) Except as permitted by this Section 6.2(b), the Board of Directors
     of the Company shall not withdraw its recommendation of the Offer or the
     Merger and other transactions contemplated hereby or approve or recommend,
     or cause the Company to enter into any agreement with respect to, any Third
     Party Acquisition. Notwithstanding the preceding sentence, if the Board of
     Directors of the Company determines in its good faith judgment, after
     consultation with legal counsel, that it is necessary to do so in order to
     comply with its fiduciary duties, the Board of Directors may withdraw its
     recommendation of the Offer or the Merger and the other transactions
     contemplated hereby, or approve or recommend or cause the Company to enter
     into an agreement with respect to a Superior Proposal (as defined below),
     but in each case only (i) after providing written notice to Parent (a
     "Notice of Superior Proposal") advising Parent that the Board of Directors
     has received a Superior Proposal, specifying the material terms and
     conditions of such Superior Proposal and identifying the Person making such
     Superior Proposal and (ii) if Parent does not, within five (5) Business
     Days (or within two (2) Business Days with respect to any amendment to any
     Superior Proposal which was noticed at least five (5) Business Days prior
     to such amendment) after Parent's receipt of the Notice of Superior
     Proposal, make an offer which the Board of
 
                                       19

     Directors of the Company determines in its good faith judgment (based on
     the advice of the Financial Advisor or another financial adviser of
     nationally recognized reputation) to be as favorable to the Company's
     stockholders as such Superior Proposal; provided, however, that the Company
     shall not be entitled to enter into any agreement with respect to a
     Superior Proposal unless this Agreement is concurrently terminated by its
     terms pursuant to Section 8.3(b). For purposes of this Agreement, "Third
     Party Acquisition" means the occurrence of any of the following events: (i)
     the acquisition of the Company by merger or otherwise by any Person (which
     includes a "person" as such term is defined in Section 13(d)(3) of the
     Exchange Act) other than Parent, Merger Sub or any Affiliate thereof (a
     "Third Party"); (ii) the acquisition by a Third Party of 20% or more of the
     total assets of the Company and its Subsidiaries, taken as a whole (other
     than the purchase of the Company's products in the ordinary course of
     business); (iii) the acquisition by a Third Party of 20% or more of the
     outstanding Shares; (iv) the adoption by the Company of a plan of partial
     or complete liquidation or the declaration or payment of an extraordinary
     dividend; (v) the repurchase by the Company or any of its Subsidiaries of
     20% or more of the outstanding Shares; or (vi) the acquisition by the
     Company or any of its Subsidiaries by merger, purchase of stock or assets,
     joint venture or otherwise of a direct or indirect ownership interest or
     investment in any business whose annual revenues, net income or assets is
     equal to or greater than 20% of the annual revenues, net income or assets
     of the Company and its Subsidiaries, taken as a whole. For purposes of this
     Agreement, a "Superior Proposal" means any bona fide proposal to acquire
     directly or indirectly for consideration consisting of cash and/or
     securities more than 50% of the Shares then outstanding or all or
     substantially all the assets of the Company and its Subsidiaries, taken as
     a whole, and otherwise on terms which the Board of Directors of the Company
     by a majority vote determines in its good faith judgment (based on
     consultation with the Financial Advisor or another financial adviser of
     nationally recognized reputation) to be reasonably capable of being
     completed (taking into account all legal, financial, regulatory and other
     aspects of the proposal and the Person making the proposal, including the
     availability of financing therefor) and more favorable to the Company's
     stockholders than the Merger.
 
     6.3.  Filings; Other Actions; Notification.
 
          (a) If a vote of the Company's stockholders is required by law, the
     Company shall promptly, following the acceptance for payment of Shares by
     Parent, pursuant to the Offer, prepare and file with the SEC the Proxy
     Statement, which shall include the recommendation of the Board of Directors
     of the Company that stockholders of the Company vote in favor of the
     approval and adoption of this Agreement and the written opinion of the
     Financial Advisor that the cash consideration to be received by the
     stockholders of the Company pursuant to the Merger is fair to such
     stockholders from a financial point of view. The Company shall use all
     reasonable efforts to have the Proxy Statement cleared by the SEC as
     promptly as practicable after such filing, and promptly thereafter mail the
     Proxy Statement to the stockholders of the Company. The Company shall also
     use its best efforts to obtain all necessary state securities law or "blue
     sky" permits and approvals required in connection with the Merger and to
     consummate the other transactions contemplated by this Agreement and will
     pay all expenses incident thereto.
 
          (b) Upon and subject to the terms and conditions set forth in this
     Agreement, the Company and Parent shall cooperate with each other and use
     (and shall cause their respective Subsidiaries to use) all reasonable
     efforts to take or cause to be taken all actions, and do or cause to be
     done all things, necessary, proper or advisable under this Agreement and
     applicable Laws to consummate and make effective the Offer, the Merger and
     the other transactions contemplated by this Agreement as soon as
     practicable, including preparing and filing as promptly as practicable all
     documentation to effect all necessary applications, notices, petitions,
     filings and other documents and to obtain as promptly as practicable all
     permits, consents, approvals and authorizations necessary or advisable to
     be obtained from any third party and/or any Governmental Entity in order to
     consummate the Offer, the Merger or any of the other transactions
     contemplated by this Agreement; provided, however, that nothing in this
     Section 6.3 shall require, or be construed to require, Parent to proffer
     to, or agree to, sell or hold separate and agree to sell, before or after
     the Effective Time, any material assets, businesses or any interest in any
     material assets or
 
                                       20
<PAGE>   26
 
     businesses of Parent, the Company or any of their respective Affiliates (or
     to consent to any sale, or agreement to sell, by the Company of any of its
     material assets or businesses) or to agree to any material change in or
     restriction on the operations of any such assets or businesses; provided
     further, that nothing in this Section 6.3 shall require, or be construed to
     require, a proffer or agreement that would, in the good faith judgment of
     Parent, be likely to have a significant adverse effect on the benefits to
     Parent of the transactions contemplated by this Agreement. Subject to
     applicable Laws relating to the exchange of information, Parent and the
     Company shall have the right to review in advance, and to the extent
     practicable each will consult the other on, all the information relating to
     Parent or the Company, as the case may be, and any of their respective
     Subsidiaries, that appears in any filing made with, or written materials
     submitted to, any third party and/or any Governmental Entity in connection
     with the Offer, the Merger and the other transactions contemplated by this
     Agreement, including the Proxy Statement. In exercising the foregoing
     right, the Company and Parent shall act reasonably and as promptly as
     practicable.
 
          (c) Each of the Company and Parent shall, upon request by the other,
     furnish the other with all information concerning itself, its Subsidiaries,
     directors, officers and stockholders and such other matters as may be
     reasonably necessary or advisable in connection with the Proxy Statement or
     any other statement, filing, notice or application made by or on behalf of
     Parent, the Company or any of their respective Subsidiaries to any
     Governmental Entity or other Person (including the NASD) in connection with
     the Offer, the Merger and the other transactions contemplated by this
     Agreement.
 
          (d) Each of the Company and Parent shall keep the other apprised of
     the status of matters relating to completion of the transactions
     contemplated hereby, including promptly furnishing the other with copies of
     notices or other communications received by Parent or the Company, as the
     case may be, or any of their respective Subsidiaries, from any third party
     and/or any Governmental Entity with respect to the Offer, the Merger and
     the other transactions contemplated by this Agreement. Each of the Company
     and Parent shall give prompt notice to the other of any change that is
     reasonably likely to have a Company Material Adverse Effect or a Parent
     Material Adverse Effect, respectively.
 
     6.4.  Information Supplied. Each of Parent and the Company agrees, as to
information provided by itself and its Subsidiaries, that none of the
information included or incorporated by reference in the proxy statement
delivered by the Company to its stockholders in connection with the Merger and
any amendment or supplement thereto (the "Proxy Statement") will, at the time
the Proxy Statement is cleared by the SEC, at the date of mailing to
stockholders of the Company, and at the time of the Stockholders Meeting (as
defined in Section 6.5),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, in light of the circumstances under which they were
made, not misleading.
 
     6.5.  Stockholders Meeting.
 
          (a) If a vote of the Company's stockholders is required by law, the
     Company will, following the acceptance for payment of Shares by Parent
     pursuant to the Offer, take, in accordance with applicable Law and its
     certificate of incorporation and by-laws, all action necessary to convene a
     meeting of holders of Shares (the "Stockholders Meeting") as promptly as
     practicable after the Proxy Statement is cleared by the SEC to consider and
     vote upon the approval of this Agreement. The Proxy Statement shall,
     include a statement that the Board approved this Agreement and recommended
     that Stockholders vote in favor of this Merger, and the Company shall use
     all reasonable and customary efforts to solicit such approval.
     Notwithstanding the foregoing, if Parent, Merger Sub and/or any other
     Subsidiary of Parent shall acquire at least 90% of the outstanding Shares,
     the parties shall take all necessary and appropriate action to cause the
     Merger to become effective as soon as practicable after the expiration of
     the Offer without a Stockholders Meeting in accordance with Section 253 of
     the DGCL.
 
          (b) Parent agrees to cause all Shares purchased pursuant to the Offer
     and all other Shares owned by Parent or any Subsidiary of Parent to be
     voted in favor of the Merger.

     6.6.  Access.  Upon reasonable notice, and except as may otherwise be
required by applicable law or relevant contractual provisions contained in such
agreements, the Company shall (and shall cause its Subsidiaries to) (i) afford
Parent's officers, employees, counsel, accountants and other authorized
representatives (collectively, "Representatives") access, during normal business
hours throughout the period prior to the Effective Time, to its properties,
books, contracts and records and, during such period, (ii) furnish promptly to
Parent all information concerning its business, properties and personnel as may
reasonably be requested; provided, however, that no investigation pursuant to
this Section 6.6 shall affect or be deemed to modify any representation or
warranty made by the Company. All requests for information made pursuant to this
Section 6.6 shall be directed to an executive officer of the Company or such
Person as may be designated by its officers. Notwithstanding the foregoing, the
parties shall comply with, and shall cause their respective Representatives to
comply with, all their respective obligations under the Confidentiality
Agreement, dated July 22, 1997, between the Company and Parent.
 
     6.7.  Publicity.  The initial press release concerning the Merger has been
approved by Parent and the Company and thereafter the Company and its
Subsidiaries, on the one hand, and Parent and Merger Sub, on the other hand,
shall consult with each other prior to issuing any press releases or otherwise
making public announcements with respect to the Merger and the other
transactions contemplated by this Agreement and prior to making any filings with
any Governmental Entity or other Person (including the NASD) with respect
hereto, except as may be required by law or by obligations pursuant to any
listing agreement with the National Market.
 
     6.8.  Status of Company Employees; Company Stock Options; Employee
Benefits.
 
          (a) Except as contemplated by this Agreement, Parent agrees that, for
     a period of twelve (12) months following the Effective Time, the Surviving
     Corporation shall maintain employee benefits plans and arrangements
     (directly or in conjunction with Parent) which, in the aggregate, will
     provide a level of benefits to Continuing Employees of the Surviving
     Corporation and its Subsidiaries similar to those provided under the
     Compensation and Benefit Plans as in effect immediately prior to the
     Effective Time (other than discretionary benefits); provided, however, that
     Parent may cause modifications to be made to such employee benefit plans
     and arrangements to the extent necessary to comply with applicable Law or
     to reflect widespread adjustments in benefits (or costs thereof) provided
     to employees under compensation and benefit plans of Parent and its
     Subsidiaries, and no specific Compensation and Benefit Plans need be
     provided. Parent shall use Continuing Employee's hire date with Company as
     the basis for determining eligibility and vesting of Parent's defined
     benefit and Supplemental Employee Retirement Medical Account (SERMA) plans.
     Parent shall use Effective Time as the basis for determining eligibility
     under the Parent's sabbatical plan and for determining benefit accruals
     under Parent's defined benefit and SERMA plans. For purposes of determining
     eligibility and vesting with respect to all other benefits maintained by
     Parent, Parent shall use Continuing Employee's hire date with the Company.
     Nothing in this Section 6.8(a) shall be construed or applied to restrict
     the ability of the Surviving Corporation and its Subsidiaries to establish
     such types and levels of compensation and benefits as they determine to be
     appropriate.
 
          (b) From and after the date hereof, the Company agrees that, except
     with respect to grants in connecti
