                         AGREEMENT AND PLAN OF MERGER

     This AGREEMENT AND PLAN OF MERGER is made and entered into as of November
24, 2000, by and among Agilent Technologies, Inc., a Delaware corporation
("Parent"), Tahoe Acquisition Corp., a Delaware corporation and a wholly-owned
subsidiary of Parent ("Merger Sub"), and Objective Systems Integrators, Inc., a
Delaware corporation (the "Company" or "Company").

                                   RECITALS
                                   --------

     A.   The Boards of Directors of the Company, Parent and Merger Sub have
each (i) determined that the Merger (as defined in Section 2.1) is advisable and
fair and in the best interests of their respective stockholders and (ii)
approved the Merger upon the terms and subject to the conditions set forth in
this Agreement;

     B.   In furtherance thereof, it is proposed that Merger Sub shall, as
promptly as practicable, commence a tender offer (the "Offer") to acquire all of
the outstanding shares (the "Shares") of Company Common Stock (as defined in
Section 2.6), at a price of Seventeen Dollars and Seventy Five Cents ($17.75)
per Share, net to the seller in cash (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

     C.   Concurrently with the execution of this Agreement, as a condition and
inducement to Parent's willingness to enter into this Agreement, certain
affiliates of Company are entering into Tender and Voting Agreements in
substantially the form attached hereto as Exhibit A (the "Company Tender and
                                          ---------
Voting Agreements").

     NOW, THEREFORE, in consideration of the foregoing premises and the
representations, warranties, covenants and agreements herein contained, and
intending to be legally bound hereby, the Company, Parent and Merger Sub hereby
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 ten business days after the date hereof, Merger Sub shall (and Parent shall
cause Merger Sub to) 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 Merger Sub to
accept for payment and to pay for any Shares tendered (and the obligation of
Parent to cause Merger Sub to accept for payment and to pay for any Shares
tendered) shall be subject only to (i) the condition that each of (A) a majority
of Shares on a fully-diluted basis (including for purposes of such calculation
<PAGE>

all Shares issuable upon exercise of all vested Company Stock Options (as
defined in Section 6.8(a)) and unvested Company Stock Options that vest prior to
the End Date (as defined in Section 8.1, but excluding any Shares held by the
Company or any of its subsidiaries) and (B) a majority of those Shares not held
by persons who have executed Company Tender and Voting Agreements be validly
tendered (but excluding any Shares held by Parent, Merger Sub or their
respective affiliates) (collectively, the "Minimum Condition"), and (ii) the
other conditions set forth in Annex A. Merger Sub expressly reserves the right
to increase the Offer Price or to make any other changes in the terms and
conditions of the Offer; provided, however, that unless previously approved by
                         --------  -------
the Company in writing, no change may be made that (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
any other conditions to the Offer or amends the conditions set forth in Annex A
to broaden the scope of such conditions, (v)  extends the Offer except as
provided in Section 1.1(b), (vi) amends or waives the Minimum Condition or (vii)
amends any other terms of the Offer in a manner adverse to the holders of the
Shares.  It is agreed that the conditions set forth in Annex A are for the sole
benefit of Parent and Merger Sub and may be waived by Parent and Merger Sub, in
whole or in part at any time and from time to time, in their sole discretion,
other than the Minimum Condition, as to which prior written Company approval is
required. The failure by Parent and Merger Sub 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 that 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 will be tendered in the Offer.

          (b)  Subject to the terms and conditions thereof, the Offer shall
expire at midnight, New York 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 (the "Company Board"), Merger Sub
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; (iii) if the number of Shares tendered pursuant
to the Offer is less than 90% of the outstanding Shares but at least 80% of the
outstanding Shares, extend the Offer for any reason on one or more occasions for
an aggregate period of not more than ten (10) 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 (and
not properly withdrawn) at least 90% of the outstanding Shares; or (iv) include
a subsequent offering period (as such term is defined in Rule 14d-1 under the
Exchange Act) to the Offer for a period up to twenty (20) business days. Parent
and Merger Sub agree that, if any one or more of the conditions to the Offer set
forth on Annex A are not satisfied and none of the events set forth in
paragraphs (b), (d), (e) or (h) of Annex A that would permit Merger Sub not to
accept tendered Shares for payment has occurred and is continuing at the time of
any scheduled expiration date of the Offer, then, provided that such conditions
                                                  --------
are reasonably capable of being satisfied in Parent and Merger Sub's reasonable
judgment, Merger Sub shall, at the request of the Company, extend the Offer from
time to time unless any such condition is no longer reasonably capable of being
satisfied or any such event has

                                       2
<PAGE>

occurred; provided, however, that in no event shall Merger Sub be required to
          --------  -------
extend the Offer beyond January 31, 2001. Subject to the terms and conditions of
the Offer and this Agreement, Merger Sub shall (and Parent shall cause Merger
Sub to) accept for payment, and pay for, all Shares validly tendered and not
withdrawn pursuant to the Offer that Merger Sub 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
and Merger Sub shall file with the SEC a Tender Offer Statement on Schedule TO
(together with all amendments and supplements thereto, and including all
exhibits thereto, the "Schedule TO") with respect to the Offer. The Schedule TO
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 they shall cause the Schedule
TO, the Offer to Purchase and all amendments or supplements thereto (which
together constitute the "Offer Documents") to comply in all material respects
with the Exchange Act and the rules and regulations thereunder and other Legal
Requirements (as defined in Section 3.3).  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 in writing specifically for inclusion or
incorporation by reference in the Offer Documents. The Company agrees that the
information provided by the Company in writing specifically 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 TO 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 and Merger Sub
agree to provide in writing to the Company and its counsel with any comments
Parent, Merger Sub or their counsel may receive from the SEC or its staff with
respect to the Offer Documents promptly after receipt of such comments.

     1.2  Company Actions.
          ---------------

          (a)  The Company hereby approves of and consents to the Offer and
represents that the Company Board, at a meeting duly called and held, has,

designees to the Company Board pursuant to this Section 1.3 and prior to the
Effective Time (the "Appointment Date"), if there shall be any Continuing
Directors, any amendment of this Agreement, any termination of this Agreement by

of the obligations or other acts of Parent or Merger Sub or any waiver of any of
the Company's rights hereunder or any other determination with respect to any
action to be taken or not to be taken by the Company relating to this Agreement,

Corporation or the Payment Agent with respect to the Certificates alleged to
have been lost, stolen or destroyed.

and Parent shall have the right to direct in all negotiations and proceedings
with respect to any such demands. Neither Company nor the Surviving Corporation
shall, except with the prior written consent of Parent, voluntarily make any
payment with respect to, or settle or offer to settle, any such demand for
payment. If any Dissenting Shareholder shall fail to perfect or shall have

Dissenting Shareholder shall thereupon be treated as though such Shares had been
converted into the right to receive the merger consideration set forth in
Article II.

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

          (a)  Each of Company and its subsidiaries is a corporation duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its incorporation and has the requisite corporate power and
authority to own, lease and operate its assets and properties and to carry on
its business as it is now being conducted, except where the failure to do so
would not, individually, or in the aggregate, have a Material Adverse Effect (as
defined in Section 9.3 below) on Company. Each of Company and its subsidiaries
is in possession of all franchises, grants, authorizations, licenses, permits,
variances, easements, consents, certificates, approvals and orders ("Approvals")
necessary to own, lease and operate the properties it purports to own, operate
or lease and to carry on its business as it is now being conducted, except where
the failure to have such Approvals would not, individually or in the aggregate,
have a Material Adverse Effect on Company. Company and its subsidiaries have
been and are in compliance with the terms of the Approvals, except where the
failure to or have been in compliance would not result in a Material Adverse
Effect on Company.

          (b)  Section 3.1(b) of the Company Schedule lists each of Company's
subsidiaries, the jurisdiction of incorporation of each such subsidiary, and
Company's equity interest therein. Neither Company nor any of its subsidiaries

partnership, joint venture or other business, association or entity.

          (c)  Company and each of its subsidiaries is qualified to do business
as a foreign corporation, and is in good standing, under the laws of all

furnished to Parent a complete and correct copy of its Certificate of
Incorporation and Bylaws as amended to date (together, the "Company Charter

documents of each of its subsidiaries are in full force and effect. Company is
not in violation of any of the provisions of the Company Charter Documents, and

                                       10

               (i)  "Hazardous Material" is any material or substance that is
                     ------------------
prohibited or regulated by any Environmental Law or that has been designated by
any governmental authority to be radioactive, toxic, hazardous or otherwise a
danger to health, reproduction or the environment.

               (ii) "Environmental Laws" are all applicable Laws, rules,
                     ------------------
regulations, orders, treaties, statutes, and codes promulgated by any
governmental authority which prohibit, regulate or control any Hazardous
Material or any Hazardous Material activity, including, without limitation, the
Comprehensive Environmental Response, Compensation, and Liability Act of 1980,
the Resource Recovery and Conservation Act of 1976, the Federal Water Pollution
Control Act, the Clean Air Act, the Hazardous Materials Transportation Act, the
Clean Water Act, comparable laws, rules, regulations, ordinances, orders,
treaties, statutes, and codes of other governmental authorities, the regulations
promulgated pursuant to any of the foregoing, and all amendments and
modifications of any of the foregoing, all as amended to date.

          (b)  Neither Company nor any of its subsidiaries is in conflict with,
or in default or violation of, any law, rule (including Environmental Laws),
regulation, order, judgment or decree applicable to Company or any of its
subsidiaries or by which its or any of their respective properties is bound or
affected, except where such conflict, default or violation does not have or
could not reasonably be expected to have a Material Adverse Effect. No
investigation or review by any governmental or regulatory body or authority is
pending or, to the knowledge of Company, threatened against Company or its
subsidiaries, nor has any governmental or regulatory body or authority indicated
to Company an intention to conduct the same, other than, in each such case,
those the outcome of which could not, individually or in the aggregate,
reasonably be expected to have the effect of prohibiting or materially impairing
any business practice of Company or any of its subsidiaries, any acquisition of
material property by Company or any of its subsidiaries or the conduct of
business by Company or any of its subsidiaries.

          (c)  The Company has not disposed of, released, discharged or emitted
any Hazardous Materials into the soil or groundwater at any properties owned or
leased at any time by the Company, or at any other property, or exposed any
employee or other individual to any Hazardous Materials or any workplace or
environmental condition in such a manner as would result in any material
liability or clean-up obligation of any kind or nature to the Company. To the
knowledge of Company, no Hazardous Materials are present in, on, or under any
properties owned, leased or used at any time by the Company, and no reasonable
likelihood exists that any Hazardous Materials will come to be present in, on,
or under any properties owned, leased or used at any time by the Company, so as
to give rise to any material liability or clean-up obligation under any
Environmental Laws.

provision in the Company's accounts (or the accounts of any subsidiary or
Affiliate) in relation to that unfunded International Employee Plan is at least

party with respect to the Company Intellectual Property. Company and each of its
subsidiaries has taken reasonable actions to maintain and protect its Company

efforts to enforce a policy requiring each employee and contractor to execute a
proprietary information/confidentiality agreement substantially in the form
provided to Parent and all current and former employees and contractors of
Company and any of its subsidiaries have executed such an agreement, except

of Directors of Company shall submit this Agreement to Company's stockholders

          -------------------
Company Stockholders' Meeting after the Appointment Date for the purpose of
voting upon the adoption and approval of this Agreement and the approval of the
Merger pursuant to the Proxy Statement, and Company shall use all reasonable
efforts to hold the Company Stockholders' Meeting as soon as practicable.
Nothing herein shall prevent Company from adjourning or postponing the Company

          (a) From and after the date of this Agreement until the Effective Time

however, that nothing contained in this Section 6.4 shall prohibit the Company,
-------
the Company Board (or any duly appointed and empowered committee thereof (a
"Special Committee")) or any director of the Company from (i) complying with
Rule 14d-9 or 14e-2(a) promulgated under the Exchange Act with regard to a
tender or exchange offer not made after a violation of this Section 6.4, (ii)
making such disclosures to Company's stockholders as in the good faith judgment
of the Company Board (or a Special Committee), after consultation with its
outside legal counsel, is required under applicable Law or (iii) in response to
an unsolicited, bona fide written Acquisition Proposal that the Company Board
(or a Special Committee) concludes in good faith constitutes a Superior Proposal
(as defined below), engaging in discussions or participating in negotiations
with and furnishing information to the party making such Acquisition Proposal to
the extent (A) the Company Board determines in good faith after consultation
with its outside legal counsel that its fiduciary obligations under applicable
Law require it to do so, (B)  (x) at least two business days prior to furnishing
any such nonpublic information to, or entering into discussions or negotiations
with, such party, Company gives Parent written notice of Company's intention to
furnish nonpublic information to, or

enter into discussions or negotiations with, such party and (y) Company receives
from such party an executed confidentiality agreement containing customary
limitations on the use and disclosure of all nonpublic written and oral
information furnished to such party by or on behalf of Company, and (C)
contemporaneously with furnishing any such nonpublic information to such party,
Company furnishes such nonpublic information to Parent (to the extent such
nonpublic information has not been previously furnished by Company to Parent).
Company and its subsidiaries will immediately cease any and all existing
activities, discussions or negotiations with any parties conducted heretofore
with respect to any Acquisition Proposal. Without limiting the foregoing, it is
understood that any violation of the restrictions set forth in this Section 6.4
by any officer, director, affiliate or employee of Company or any of its
subsidiaries or any investment banker, attorney or other advisor or
representative of Company or any of its subsidiaries shall be deemed to be a
breach of this Section 6.4 by Company.

     For purposes of this Agreement: (i) "Acquisition Proposal" shall mean any
expression of interest, offer or proposal (other than an offer or proposal by
Parent) relating to any Acquisition Transaction; (ii) "Acquisition Transaction"
shall mean any transaction or series of related transactions other than the
transactions contemplated by this Agreement involving: (A) any acquisition or
purchase from Company by any person or "group" (as defined under Section 13(d)
of the Exchange Act and the rules and regulations thereunder) of more than a 15%
interest in the total outstanding voting securities of Company or any of its
subsidiaries or any tender offer or exchange offer that if consummated would
result in any person or "group" (as defined under Section 13(d) of the Exchange
Act and the rules and regulations thereunder) beneficially owning 15% or more of
the total outstanding voting securities of Company or any of its subsidiaries or
any merger, consolidation, business combination or similar transaction involving
Company pursuant to which the shareholders of Company immediately preceding such
transaction hold less than 85% of the equity interests in the surviving or
resulting entity of such transaction; (B) any sale, lease (other than in the
ordinary course of business), exchange, transfer, license (other than in the
ordinary course of business), acquisition or disposition of more than 15% of the
assets of Company; or (C) any liquidation, dissolution, recapitalization or
other significant corporate reorganization of Company; and (iii) "Superior

means of any of the structural means described in clauses (A) or (B) of the
definition of Acquisition Transaction) of a majority of the outstanding voting
securities, or all or substantially all of the assets, of the Company with
respect to which (A) if any cash consideration is involved, no financing
contingency exists or the Company Board shall have concluded in good faith
(after consultation with Company's financial advisors) that the acquiring party
is reasonably likely to obtain any necessary financing, and (B) the Company
Board shall have concluded in good faith that the proposed Acquisition
Transaction provides greater value to the stockholders of Company than the Offer
and the Merger (based upon the advice of Company's financial advisors).

          (b) In addition to the obligations of Company set forth in paragraph
(a) of this Section 6.4, Company as promptly as practicable, and in any event
within one business day, shall advise Parent orally and in writing of any
request for information which Company reasonably believes would lead to an
Acquisition Proposal or of any Acquisition Proposal, or any inquiry with

                                       36
<PAGE>

Proposal; the material terms and conditions of such request, Acquisition
Proposal or inquiry; and the identity of the person or group making any such
request, Acquisition Proposal or inquiry. Company will keep Parent informed in
all material respects of the status and details (including material amendments
or proposed amendments) of any such request, Acquisition Proposal or inquiry. In
addition to the foregoing, Company shall (i) provide Parent with at least 48
hours prior written notice (or such lesser prior notice as provided to the
members of the Company Board but in no event less than eight hours) of any
meeting of the Company Board at which Company's Board is reasonably expected to
consider an Acquisition Proposal and (ii) provide Parent with at least two (2)
business days prior written notice (or such lesser prior notice as provided to

          -----------------
and to the extent practicable, agree, before issuing any press release or
otherwise making any public statement with respect to the Offer, this Agreement
or an Acquisition Proposal and will not issue any such press release or make any
such public statement prior to such consultation, except as may be required by
law or any listing agreement with a national securities exchange, in which case
reasonable efforts to consult with the other party will be made prior to any
such release or public statement.

     6.6  Commercially Reasonable Efforts; Notification.
          ---------------------------------------------

          (a) Upon the terms and subject to the conditions set forth in this
Agreement, each of the parties agrees to use all commercially reasonable efforts
to take, or cause to be taken, all actions, and to do, or cause to be done, and
to assist and cooperate with the other parties in doing, all things necessary,
proper or advisable to consummate and make effective, in the most expeditious
manner practicable, the transactions contemplated by this Agreement, including
using commercially reasonable efforts to accomplish the following: (i) the
taking of all commercially reasonable acts necessary to cause the conditions
precedent set forth in Article VII to be satisfied, (ii) the obtaining of all
necessary actions or nonactions, waivers, consents, approvals, orders and
authorizations from Governmental Entities and the making of all necessary
registrations, declarations and filings (including registrations, declarations
and filings with Governmental Entities, if any) and the taking of all
commercially reasonable steps as may be necessary to avoid any suit, claim,
action, investigation or proceeding by any Governmental Entity, (iii) the
defending of any suits, claims, actions, investigations or proceedings, whether
judicial or administrative, challenging this Agreement or the consummation of
the transactions contemplated hereby, including seeking to have any stay or
temporary restraining order entered by any court or other Governmental Entity
vacated or reversed and (iv) the execution or delivery of any additional
instruments reasonably necessary to consummate the transactions contemplated by,
and to fully carry out the purposes of, this Agreement. In connection with and
without limiting the foregoing, Company and its Board of Directors shall, if any

to this Agreement or any of the transactions contemplated by this Agreement, use
all commercially reasonable efforts to

                                       37
<PAGE>

ensure that the transactions contemplated by this Agreement may be consummated
as promptly as practicable on the terms contemplated by this Agreement and
otherwise to minimize the effect of such statute or regulation on this Agreement
and the transactions contemplated hereby. Notwithstanding anything herein to the
contrary, nothing in this Agreement shall be deemed to require Parent or Company
or any subsidiary or affiliate thereof to agree to any divestiture by itself or
any of its affiliates of shares of capital stock or of any business, assets or
property, or the imposition of any material limitation on the ability of any of
them to conduct their business or to own or exercise control of such assets,
properties and stock.

          (b) Company shall give prompt notice to Parent upon becoming aware
that any representation or warranty made by it contained in this Agreement has
become untrue or inaccurate, or of any failure of Company to comply with or
satisfy in any material respect any covenant, condition or agreement to be
complied with or satisfied by it under this Agreement; provided, however, that
                                                       --------  -------
no such notification shall affect the representations, warranties, covenants or
agreements of the parties or the conditions to the obligations of the parties
under this Agreement.

          (c) Parent shall give prompt notice to Company upon becoming aware
that any representation or warranty made by it or Merger Sub contained in this
Agreement has become untrue or inaccurate, or of any failure of Parent or Merger
Sub to comply with or satisfy in any material respect any covenant, condition or
agreement to be complied with or satisfied by it under this Agreement; provided,
                                                                       --------
however, that no such notification shall affect the representations, warranties,

     6.8  Stock Options and Employee Benefits.
          -----------------------------------

          (a) Stock Options.  At the Effective Time, each outstanding option to
              -------------
purchase shares of Company Common Stock (each, a "Company Stock Option") under
the Company Option Plans, whether or not vested, shall by virtue of the Merger
be substituted with an equivalent option under Parent's option plan.  Each
Company Stock Option so substituted by Parent under this Agreement and will be
exercisable (or will become exercisable in accordance with its terms) for that
number of whole shares of Parent Common Stock equal to the product of the number
of shares of Company Common Stock that were issuable upon exercise of such
Company Stock Option immediately prior to the Effective Time multiplied by the
product of that fraction of a share of Common Stock, $0.01 par value per share,
of Parent (the "Parent Common Stock") obtained by dividing $17.75 by the average
of the closing prices of Parent's Common Stock as quoted on the New York Stock
Exchange ("NYSE") for the five (5) trading days immediately preceding the
closing date (the "Exchange Ratio"), rounded down to the nearest whole number of
shares of Parent

                                       38
<PAGE>

Common Stock and (ii) the per share exercise price for the shares of Parent
Common Stock issuable upon exercise of such substituted Company Stock Option
will be equal to the quotient determined by dividing the exercise price per
share of Company Common Stock at which such Company Stock Option was exercisable
immediately prior to the Effective Time by the product of the Exchange Ratio,
rounded up to the nearest whole cent. Parent shall comply with the terms of all
such substituted Company Stock Options and use its best efforts to ensure, to
the extent required by, and subject to the provisions of, the Company Option
Plans and permitted under the Code that any Company Stock Options that qualified
for tax treatment under Section 424(b) of the Code prior to the Effective Time
continue to so qualify after the Effective Time. Parent shall take all corporate
actions necessary to reserve for issuance a sufficient number of shares of
Parent Common Stock for delivery pursuant to the terms set forth in this Section
6.8 (a).

          (b) Employee Stock Purchase Plan.  Company agrees that it shall take
              ----------------------------
such actions as is necessary(i) to provide that the shares of the Company Common
Stock to be purchased under the Company Employee Stock Purchase Plan shall be
purchased under the Company Employee Stock Purchase Plan on a "New Exercise
Date" (as such term is defined in the Company Employee Stock Purchase Plan) set
by the Board of Directors, which Exercise Date shall be on the last trading day
immediately prior to the Effective Time, and (ii) to provide that immediately
following such purchase of shares of Company Common Stock the Company Employee
Stock Purchase Plan shall terminate.

          (c) 401(k) Plan. Company shall terminate, effective as of the day
              -----------
immediately preceding the Effective Time, any and all 401(k) plans unless Parent
provides notice to Company that such 401(k) plan(s) shall not be terminated.
Parent shall receive from Company evidence that Company's plan(s) and /or
program(s) have been terminated pursuant to resolutions of each such entity's
Board of Directors (the form and substance of such resolutions shall be subject
to review and approval of Parent), effective as of the day immediately preceding
the Effective Time.

          (d) Benefit Plans; Credit for Past Service. Parent shall cause Merger
              --------------------------------------
Sub and the Surviving Corporation to provide employees of the Company and its
Subsidiaries with benefits (including welfare benefits) that are substantially
similar as it provides to its similarly-situated employees.  To the extent that
service is relevant for eligibility, vesting or allowances (including flexible
time off) under any plan, program or arrangement of the  Merger Sub and/or
Surviving Corporation, then Parent shall ensure that such plan, program or
arrangement shall credit employees for service prior to the Effective Time with
the Company and its Subsidiaries; provided, however, no such service shall be
credited for any purpose under Parent's pension plan and Parent's retiree health
plan.  Notwithstanding anything in this Section 6.8(d) to the contrary, nothing
in this Section 6.8(d) shall be deemed to limit or otherwise affect the right of
the Parent, Merger Sub or the Surviving Corporation to terminate employment or
change the place of work, responsibilities, status or description of any
employee or group of employees as the Parent, Merger Sub or Surviving
Corporation may determine in its discretion.

                                       39
<PAGE>

     6.9  Adjustments to Exchange Ratio.  The Exchange Ratio shall be adjusted
          -----------------------------
to reflect appropriately the effect of any stock split, reverse stock split,
stock dividend (including any dividend or distribution of securities convertible
into Parent Common Stock or Company Common Stock), extraordinary cash dividends,
reorganization, recapitalization, reclassification, combination, exchange of
shares or other like change with respect to Parent Common Stock or Company
Common Stock occurring on or after the date hereof and prior to the Effective
Time.

     6.10 [Intentionally omitted.]
          ----------------------

     6.11 Indemnification.
          ---------------

          (a) From and after the Effective Time, Parent will cause the Surviving
Corporation to fulfill and honor in all respects the obligations of Company
pursuant to any indemnification agreements between Company and its directors and
officers in effect immediately prior to the Effective Time (the "Indemnified
Parties") and any indemnification provisions under the Company Charter Documents
as in effect on the date hereof.  The Certificate of Incorporation and Bylaws of
the Surviving Corporation will contain provisions with respect to exculpation
and indemnification that are at least as favorable to the Indemnified Parties as
those contained in the Company Charter Documents as in effect on the date
hereof, which provisions will not be amended, repealed or otherwise modified for
a period of six (6) years from the Effective Time in any manner that would
adversely affect the rights thereunder of individuals who, immediately prior to
the Effective Time, were directors, officers, employees or agents of Company,
unless such modification is required by law.

          (b) For a period of six (6) years after the Effective Time, Parent
will cause to be maintained in effect, if available, directors' and officers'
liability insurance covering those persons who are currently covered by
Company's directors' and officers' liability insurance policy with respect to
claims arising from or related to facts or events which occurred at or before
the Effective Time in an amount and on terms comparable to those applicable to
the current directors and officers of Company; provided, however, that in no
                                               --------  -------
event will Parent or the Surviving Corporation be required to expend an annual
premium for such coverage in excess of 150% of the annual premium currently paid
by Company; provided, further, that if the premium for such coverage exceeds
            --------  -------
such amount, Parent and/or the Surviving Corporation shall purchase a policy
with the greatest coverage available for 150% of the annual premium currently
paid by Company.

          (c) In the event Company or the Surviving Corporation or any of their
respective successors or assigns (i) consolidates with or merges into any other
person and shall not be the continuing or surviving corporation or entity of
such consolidation or merger or (ii) transfers a material amount of its
properties and assets to any person in a single transaction or a series of
transactions, then, and in each such case, Parent will either guaranty the
indemnification obligations referred to in this Section 6.11 or will make or
cause to be made proper provision so that the successors and assigns of Company
or the Surviving Corporation, as the case may be, assume the indemnification
obligations described herein for the benefit of the Indemnified Parties.

                                       40
<PAGE>

          (d)  The provisions of this Section 6.11 are (i) intended to be for
the benefit of, and will be enforceable by, each of the Indemnified Parties and
(ii) in addition to, and not in substitution for, any other rights to
indemnification or contribution that any such person may have by contract or
otherwise.

     6.12 Regulatory Filings; Reasonable Efforts.  As soon as may be reasonably
          --------------------------------------
practicable, Company and Parent each shall file with the United States Federal
Trade Commission (the "FTC") and the Antitrust Division of the United States
Department of Justice ("DOJ") Notification and Report Forms relating to the
transactions contemplated herein as required by the HSR Act, as well as
comparable pre-merger notification forms required by the merger notification or
control laws and regulations of any applicable jurisdiction, as agreed to by the
parties. Except where prohibited by applicable Law, and subject to the
Confidentiality Agreement, Company and Parent each shall promptly (a) supply the
other with any information which may be required in order to effectuate such
filings and (b) supply any additional information which reasonably may be
required by the FTC, the DOJ or the competition or merger control authorities of
any other jurisdiction and which the parties may reasonably deem appropriate.

                           CONDITIONS TO THE MERGER

     7.1  Conditions.  The respective obligations of each party to consummate
          ----------
the Merger shall be subject to the satisfaction or waiver, where permissible,
prior to the Effective Time, of the following conditions:

          (a)  Stockholder Approval.  If approval of the Merger by the holders
               --------------------

approved by the holders of a majority of the outstanding shares of each class of
the Company entitled to vote on the Merger, in accordance with applicable Law
and the Certificate of Incorporation and Bylaws of the Company;

          (b)  Purchase of Shares.  Merger Sub (or Parent) shall have purchased
               ------------------
Shares pursuant to the Offer; and

          (c)  No Order.  No court or other Governmental Entity of competent
               --------
jurisdiction shall have enacted, issued, promulgated, enforced or entered any
statute, rule, regulation, judgment, decree, injunction or other order (whether
temporary, preliminary or permanent) which is in effect and prohibits
consummation of the Merger (collectively, an "Order").

                                 ARTICLE VIII
                       TERMINATION, AMENDMENT AND WAIVER

     8.1  Termination.  This Agreement may be terminated and the Merger may be
          -----------
abandoned at any time prior to the Effective Date (notwithstanding any approval
of this Agreement by the stockholders of Company):

                                       41
<PAGE>

          (a)  by mutual written agreement of Company and Parent; or

          (b)  by either Company or Parent, if:

               (i)   the Offer shall have expired or been terminated in
accordance with the terms of this Agreement without Parent or Merger Sub having
accepted for exchange any Shares pursuant to the Offer, provided that Parent and
                                                        --------
Merger Sub shall not be permitted to terminate this Agreement pursuant to this
Section 8.1(b)(i) if the Offer is terminated or expires without Shares having
been accepted for exchange as a result of a breach by Parent or Merger Sub of
this Agreement; or

               (ii)  the Offer has not been consummated on or before January 31,
2001 (the "End Date"); provided, however, that the right to terminate this
                       --------  -------
Agreement under this Section 8.1(b)(ii) shall not be available to any party
whose failure to fulfill any obligation under this Agreement has been the
principal cause of or resulted in the failure of the Offer to have been
consummated on or before such date and such action or failure to act constitutes
a material breach of this Agreement; or

               (iii) there shall be any applicable Law or regulation that makes
consummation of the Merger illegal or otherwise prohibited or any judgment,
injunction, order or decree of any court or governmental body having competent
jurisdiction enjoining Company or Parent from consummating the Merger is entered
and such judgment, injunction, judgment or order shall have become final and
nonappealable; or

               (iv)  Prior to the Appointment Date (A) any of the
representations and warranties of the other party set forth in this Agreement
shall not be true and correct in all respects (unless such failures to be true
and correct, without giving effect to any materiality or Material Adverse Effect
qualifications or exceptions contained therein, do not, or could not reasonably
be expected to, constitute a Material Adverse Effect with respect to Company),
in each case (i) as of the date referred to in any representation or warranty
which addresses matters as of a particular date, or (ii) as to all other
representations and warranties of the other party, as of the date of this
Agreement and as of the scheduled expiration of the Offer, or (B) the other
party shall have failed to perform in any material respect any material
obligation or to comply in any material respect with any material agreement or
covenant of such party to be performed or complied with by it under this
Agreement; provided, however, that such inaccuracy or failure to perform has not
           --------  -------
been or is incapable of being cured by such other party within 30 days following
receipt by the terminating party of notice of such inaccuracy or failure to
perform;

          (c)  by Parent if a Triggering Event shall have occurred; or

          (d)  by Company, if the Offer has not been commenced by the Parent or
Merger Sub on or prior to ten (10) business days following the date of the
initial public announcement of the Offer, provided, that Company may not
                                          --------
terminate this agreement pursuant to this Section 8.1(d) if Company is in
material breach of this Agreement.

                                       42
<PAGE>

     For purposes of this Agreement, a "Triggering Event" shall be deemed to
have occurred if, prior to the Effective Time:  (i) the Board of Directors of
Company or any committee thereof shall have approved or recommended to Company
stockholders any Acquisition Proposal, (ii) the Board of Directors of Company or
any committee thereof shall for any reason have withdrawn or shall have amended
or modified in a manner adverse to Parent its recommendation in favor of the
Offer, the adoption and approval of the Agreement or the approval of the Merger
(the "Recommendations"); (iii) Company shall have failed to include the
Recommendations in the Offer Documents or the Schedule 14D-9; (iv) Company shall
have breached the provisions of Section 6.4; or (v) an Acquisition Proposal
shall have been commenced or otherwise publicly announced by a person
unaffiliated with Parent, and Company shall not, within 10 business days after
such commencement or public announcement, publicly recommended to the Company's
stockholders rejection of such Acquisition Proposal.

     The party desiring to terminate this Agreement pursuant to this Section 8.1
(other than pursuant to Section 8.1(a)) shall give notice of such termination to
the other party.

     8.2  Notice of Termination; Effect of Termination.  Any proper termination
          --------------------------------------------
of this Agreement under Section 8.1 above will be effective immediately upon the
delivery of written notice of the terminating party to the other parties hereto.
In the event of the termination of this Agreement under Section 8.1, this
Agreement shall be of no further force or effect without liability of any party
(or any stockholder, director, officer, employee, agent, consultant or
representative of such party) to the other parties hereto, except (i) as set
forth in this Section 8.2, Section 8.3 and Article IX, each of which shall
survive the termination of this Agreement, and (ii) that nothing herein shall
relieve any party from liability for any willful breach of or fraud in
connection with this Agreement. No termination of this Agreement shall affect
the obligations of the parties contained in the Confidentiality Agreement, all
of which obligations shall survive termination of this Agreement in accordance
with their terms. In the event that Company gives Parent notice of an inaccuracy
or failure to perform such that this Agreement would be subject to termination
pursuant to Section 8.1(b)(iv), Parent shall cause Merger Sub to not consummate
the Offer until such inaccuracy or failure to perform is cured.

     8.3  Fees and Expenses.
          -----------------

          (a)  General.  Except as set forth in this Section 8.3, all fees and
               -------
expenses incurred in connection with this Agreement and the transactions
contemplated hereby shall be paid by the party incurring such expenses whether
or not the Merger is consummated; provided, however, that Parent and Company
                                  --------  -------
shall share equally all fees and expenses, other than attorneys' and accountants
fees and expenses, in relation to the printing, filing and mailing of the
Schedule TO and the Schedule 14D-9 and any amendments or supplements thereto.

          (b)  Company Payments.  If this Agreement is terminated by Parent or
               ----------------
Company, as applicable, prior to the Effective Time pursuant to Sections
8.1(b)(i) or (ii) or Section 8.1(c), Company shall promptly, but in any event no
later than two days after the date of such termination,

                                       43
<PAGE>

pay Parent a fee equal to $22,600,000 in immediately available funds (the
"Termination Fee"); provided, that in the case of a termination under Section
                    --------
8.1(b)(i) or (ii) prior to which no Triggering Event has occurred, (i) such
payment shall be made only if (A) following the date of this Agreement and prior
to the termination of this Agreement, any Acquisition Proposal shall have been
publicly announced or shall have become publicly known, and (B) within 12 months
following the termination of this Agreement, either a Company Acquisition (as
defined below) is consummated, or Company enters into an agreement providing for
a Company Acquisition and such Company Acquisition is later consummated, and
(ii) such payment shall be made promptly, but in any event no later than two
days after the consummation of such Company Acquisition. Company acknowledges
that the agreements contained in this Section 8.3(b) are an integral part of the
transactions contemplated by this Agreement, and that, without these agreements,
Parent would not enter into this Agreement. Accordingly, if Company fails to pay
in a timely manner the amounts due pursuant to this Section 8.3(b), and, in
order to obtain such payment, Parent makes a claim that results in a judgment
against Company, Company shall pay to Parent its reasonable costs and expenses
(including reasonable attorneys' fees and expenses) in connection with such
suit, together with interest on the amounts set forth in this Section 8.3(b) at
the prime rate Bank of America N.T. and S.A. in effect on the date such payment
was required to be made. Parent agrees that the payment provided for in this
Section 8.3(b) shall be the sole and exclusive remedy of Parent and Merger Sub
upon termination of this Agreement where such fee has been paid, and such
remedies shall be limited to the sum stipulated in this Section 8.3(b),
regardless of the circumstances giving rise to such termination; provided,
                                                                 ---------
however, that nothing herein shall relieve the Company from liability for the
-------
willful breach of, or fraud in connection with, any of its representations,
warranties, covenants or agreements set forth in this Agreement.

     For the purposes of this Agreement, "Company Acquisition" shall mean any of
the following transactions (other than the transactions contemplated by this
Agreement): (i) a sale or other disposition by Company of a business or assets
representing 40% or more of the consolidated net revenues, net income or assets
of Company immediately prior to such sale; (ii) the acquisition by any person or
group (including by way of a tender offer or an exchange offer or issuance by
Company), directly or indirectly, of beneficial ownership or a right to acquire
beneficial ownership of shares representing 40% or more of any class of equity
securities of Company; or (iii) a merger, consolidation, business combination,
recapitalization, liquidation, dissolution or similar transaction involving
Company (other than a transaction in which Company is the Parent and in which
the current Company stockholders retain more than 60%, directly or indirectly,
of the surviving or successor corporation); it being understood that a widely
distributed offering of Company Common Stock shall not constitute a Company
Acquisition.

     8.4  Amendment.  Subject to applicable Law and to Section 1.3(c), this
          ---------
Agreement may be amended by the parties hereto at any time by execution of an
instrument in writing signed on behalf of each of Parent and Company.

     8.5  Extension; Waiver.  At any time prior to the Effective Time any party
          -----------------
hereto may, to the extent legally allowed and except as otherwise set forth
herein, (i) extend the time for the

                                       44
<PAGE>

performance of any of the obligations or other acts of the other parties hereto,
(ii) waive any inaccuracies in the representations and warranties made to such
party contained herein or in any document delivered pursuant hereto and (iii)
waive compliance with any of the agreements or conditions for the benefit of
such party contained herein. Any agreement on the part of a party hereto to any
such extension or waiver shall be valid only if set forth in an instrument in
writing signed on behalf of such party. Delay in exercising any right under this
Agreement shall not constitute a waiver of such right.

                                  ARTICLE IX
                              GENERAL PROVISIONS

     9.1  Non-Survival of Representations and Warranties.  The representations,
          ----------------------------------------------
warranties and covenants of Company, Parent and Merger Sub contained in this
Agreement shall terminate at the Effective Time, and only the covenants that by
their terms survive the Effective Time shall survive the Effective Time.

reference shall be to an Exhibit to this Agreement unless otherwise indicated.
When a reference is made in this Agreement to Sections, such reference shall be

"includes" and "including" when used herein shall be deemed in each case to be

liability partnership, joint venture, estate, trust, company (including any
limited liability company or joint stock company), firm or other enterprise,
association, organization, entity or Governmental Entity.

          (e)  When used in connection with Parent or Company, as the case may
be, the term "Material Adverse Effect" means any change or effect that,
individually or when taken together with all other such changes or effects that
have occurred prior to the date of determination of the occurrence of the
Material Adverse Effect, is or is reasonably likely to be materially adverse to

results of operations of such entity and its subsidiaries, taken as a whole, or
on the ability of such entity to consummate the Offer or the Merger, but other
than those adverse effects occurring directly and primarily as a result of (i)
the execution and public announcement of this Agreement, the pendency of this
Agreement or the consummation of the transactions contemplated hereby
(including, without limitation, loss of customers, vendors, suppliers or
employees directly and primarily resulting therefrom) or (ii) general market or

documents and instruments and other agreements among the parties hereto as
contemplated by or referred to herein, including the Company Disclosure Schedule

Confidentiality Agreement shall continue in full force and effect until the
Closing and shall survive any termination of this Agreement; and (b) are not
intended to confer upon any other person any rights or remedies hereunder.

     9.6  Severability.  In the event that any provision of this Agreement, or
          ------------
the application thereof, becomes or is declared by a court of competent
jurisdiction to be illegal, void or unenforceable, the remainder of this
Agreement will continue in full force and effect and the application of such
provision to other persons or circumstances will be interpreted so as reasonably
to effect the intent of the parties hereto. The parties further agree to replace
such void or unenforceable provision of this Agreement with a valid and
enforceable provision that will achieve, to the extent possible, the economic,
business and other purposes of such void or unenforceable provision.

          ------------------------------------
herein, any and all remedies herein expressly conferred upon a party will be
deemed cumulative with and not exclusive of any other remedy conferred hereby,
or by law or equity upon such party, and the exercise by a party of any one
remedy will not preclude the exercise of any other remedy. The parties hereto

be construed against the party drafting such agreement or document.

          ----------
rights, interests, or obligations hereunder without the prior written approval
of the other parties. Subject to the preceding sentence, this Agreement shall be
binding upon and shall inure to the benefit of the parties hereto and their
respective successors and permitted assigns.

     Certain Conditions of the Offer.  Notwithstanding any other provisions of
     -------------------------------
the Offer, and in addition to (and not in limitation of) the Parent's rights to
extend and amend the Offer at any time in its sole discretion (subject to the
provisions of the Agreement), the Parent shall not be required to accept for
payment or, subject to any applicable rules and regulations of the SEC,
including Rule 14e-1(c) under the Exchange Act (relating to the Parent's
obligation to pay for or return tendered Shares promptly after termination or
withdrawal of the Offer), pay for, and may delay the acceptance for payment of
or, subject to the restriction referred to above, the payment for, any tendered
Shares, and may terminate or amend the Offer as to any Shares not then paid for,
if (i) any applicable waiting period under the HSR Act or any Foreign Filing has
not expired or terminated, (ii) the Minimum Condition has not been satisfied, or
(iii) at any time on or after the date of the Agreement and before the time of
acceptance for payment for any such Shares, any of the following events shall
occur or shall be determined by the Parent to have occurred:

          (a)  there shall be threatened or pending any suit, action or
proceeding by any Governmental Entity against the Parent, Merger Sub, the
Company or any subsidiary of the Company (i) seeking to prohibit or impose any
material limitations on Parent's or Merger Sub ownership or operation (or that
of any of their respective subsidiaries or affiliates) of all or a material
portion of their or the Company's businesses or assets, or to compel Parent,
Merger Sub or their respective subsidiaries and affiliates to dispose of or hold
separate any material portion of the business or assets of the Company or Parent
and their respective subsidiaries, in each case taken as a whole, (ii)
challenging the acquisition by Parent or Merger Sub of any Shares under the
Offer or pursuant to the Stockholder Agreements, seeking to restrain or prohibit
the making or consummation of the Offer or the Merger or the performance of any
of the other transactions contemplated by this Agreement or the Company Tender
and Voting Agreements (including the voting provisions thereunder), or seeking
to obtain from the Company, Merger Sub or the Parent any damages that are
material in relation to the Company and its subsidiaries taken as a whole, (iii)
seeking to impose material limitations on the ability of Merger Sub, or render
Merger Sub unable, to accept for payment, pay for or purchase some or all of the
Shares pursuant to the Offer and the Merger or (iv) seeking to impose material
limitations on the ability of the Parent or Merger Sub effectively to exercise
full rights of ownership of the Shares, including, without limitation, the
right, to vote the Shares purchased by it on all matters properly presented to
the Company's stockholders;

          (b)  there shall be any statute, rule, regulation, judgment, order or
injunction enacted, entered, enforced, promulgated, or deemed applicable,
pursuant to an authoritative interpretation by or on behalf of a Government
Entity, to the Offer or the Merger, or any other action shall be taken by any
Governmental Entity, other than the application to the Offer or the Merger of
applicable waiting periods under the HSR Act, that is reasonably likely to
result, directly or indirectly, in any of the consequences referred to in
clauses (i) through (iv) of paragraph (a) above;

                                      A-1
<PAGE>

          (c)  there shall have occurred (i) any general suspension of trading
in, or limitation on prices for, securities on the NYSE or in the Nasdaq, for a
period in excess of 24 hours (excluding suspensions or limitations resulting
solely from physical damage or interference with such exchanges not related to
market conditions), (ii) a declaration of a banking moratorium or any suspension
of payments in respect of banks in the United States (whether or not mandatory),
(iii) a declaration of war by the United States or (iv) in the case of any of
the foregoing existing at the time of the commencement of the Offer, a material
acceleration or worsening thereof;

          (d)  there shall have occurred and be continuing any Material Adverse
Effect with respect to the Company;

          (e)  a Triggering Event;

          (f)  any of the representations and warranties of the Company set
forth in this Agreement shall fail to be true and correct or as of the date of
this Agreement or as of the scheduled expiration of the Offer, to an extent that
would entitle Parent to terminate this Agreement pursuant to Section
8.1(b)(iv)(A) (disregarding for this purpose the notice and cure provisions
thereof);

          (g)  the Company shall have failed to perform in any material respect
any material obligation or to comply in any material respect with any material
agreement or covenant of the Company to be performed or complied with by it
under this Agreement; or

          (h)  the Agreement shall have been terminated in accordance with its
terms which in the reasonable good faith judgment of Parent or Merger Sub, in
any such case, and regardless of the circumstances (including any action or
inaction by Parent or Merger Sub) giving rise to such condition makes it
inadvisable to proceed with the Offer and/or with such acceptance for payment of
or payment for Shares.

     The foregoing conditions are for the sole benefit of Parent and Merger Sub
and may be waived by Parent or Merger Sub, in whole or in part at any time and
from time to time in the sole discretion of Parent or Merger Sub.  The failure
by Parent or Merger Sub at any time to exercise any of the foregoing rights
shall not be deemed a waiver of any such right and each such right shall be
deemed an ongoing right which may be asserted at any time and from time to time.
