                 AGREEMENT AND PLAN OF MERGER AND REORGANIZATION

        THIS AGREEMENT AND PLAN OF MERGER AND REORGANIZATION ("Agreement") is
made and entered into as of May 10, 1999, by and among: QUANTUM CORPORATION, a
Delaware corporation ("PARENT"); DEFIANT ACQUISITION SUB, INC., a Delaware
corporation and a wholly owned subsidiary of Parent ("MERGER SUB"); and MERIDIAN
DATA, INC., a Delaware corporation (the "DELAWARE COMPANY") and MERIDIAN DATA,
INC., a California corporation, to the extent such corporation is in existence,
(the "CALIFORNIA COMPANY"), (the Delaware Company and the California Company are
referred to collectively herein as the "COMPANY", and "PRINCIPAL COMPANY" shall
mean, as between the California Company and the Delaware Company, that
corporation the shares of which are registered under Section 12(g) of the
Securities Act immediately prior to the Closing). Certain capitalized terms used
in this Agreement are defined in Exhibit A.

                                    RECITALS

        A. Parent, Merger Sub and the Company intend to effect a merger of
Merger Sub into the Principal Company in accordance with this Agreement, the
Delaware General Corporation Law and such other state laws as may be applicable
(the "Merger"). Upon consummation of the Merger, Merger Sub will cease to exist,
and the Principal Company will become a wholly owned subsidiary of Parent.

        B. It is intended that the Merger qualify as a tax-free reorganization
within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as
amended (the "Code"). For financial reporting purposes, it is intended that the
Merger be accounted for as a purchase.

        C. The respective boards of directors of Parent, Merger Sub and the
Company have approved this Agreement and approved the Merger.

        D. In order to induce Parent to enter into this Agreement and to
consummate the Merger, certain stockholders of the Principal Company are
entering into Voting Agreements pursuant to which they are agreeing to vote in
favor of the adoption and approval of this Agreement and the approval of the
Merger.

                                    AGREEMENT

        The parties to this Agreement, intending to be legally bound, agree as
follows:

        SECTION 1. DESCRIPTION OF TRANSACTION

             1.1 MERGER OF MERGER SUB INTO THE PRINCIPAL COMPANY. Upon the terms
and subject to the conditions set forth in this Agreement, at the Effective Time
(as defined in Section 1.3), Merger Sub shall be merged with and into the
Principal Company, and the separate existence of Merger Sub shall cease. The
Principal Company will continue as the surviving corporation in the Merger (the
"SURVIVING CORPORATION") and be a wholly owned subsidiary of Parent.

             1.2 EFFECT OF THE MERGER. The Merger shall have the effects set
forth in this Agreement, in the applicable provisions of the Delaware General
Corporation Law (the "DGCL") and such other state laws as may be applicable.

             1.3 CLOSING; EFFECTIVE TIME. The consummation of the transactions
contemplated by this Agreement (the "CLOSING") shall take place at the offices
of Cooley Godward LLP, located at Five Palo Alto Square, 3000 El Camino Real,
Palo Alto, California, at 10:00 a.m. on a date to be mutually agreed to by
Parent and the Company (the "Closing Date"), which shall be no later than the
second business day after the satisfaction or waiver of the conditions set forth
in Sections 6 and 7. Contemporaneously with or as promptly as practicable after
the Closing, the parties hereto shall cause a properly executed certificate of
merger conforming to the requirements of the DGCL (the "CERTIFICATE OF MERGER")
to be filed with the Secretary of State of the State of Delaware and to file
such other certificates of merger or analogous documents to be filed with the
Secretary of State of such other states as may be required to effect the Merger.
The Merger shall take effect at the time the Certificate of Merger is filed with
the Secretary of State of the State of Delaware or at such later time as may be
specified in the Certificate of Merger (the "EFFECTIVE TIME").

             1.4 CERTIFICATE OF INCORPORATION AND BYLAWS; DIRECTORS AND
OFFICERS. Unless otherwise determined by Parent prior to the Effective Time:

                    (a) the Certificate of Incorporation of the Surviving
Corporation shall be the Certificate of Incorporation of Merger Sub except that
the name of the Surviving Corporation shall be Meridian Data, Inc.;

                    (b) the Bylaws of the Surviving Corporation shall be amended
and restated as of the Effective Time to conform to the Bylaws of Merger Sub as
in effect immediately prior to the Effective Time; and

                    (c) the directors and officers of the Surviving Corporation
immediately after the Effective Time shall be the respective individuals who are
directors and officers of Merger Sub immediately prior to the Effective Time.

             1.5 CONVERSION OF SHARES.

                    (a) Subject to Sections 1.5(b), 1.5(c) and 1.5(d), at the
Effective Time, by virtue of the Merger and without any further action on the

                         (i) any shares of Company Common Stock then held by the
Principal Company or any Subsidiary of the Principal Company (or held in the
Principal Company's treasury) shall be canceled and retired and shall cease to
exist at the Effective Time, and no consideration shall be delivered in exchange
therefor;

                         (ii) any shares of Company Common Stock then held by
Parent, Merger Sub or any other Subsidiary of Parent shall be canceled and
retired and shall cease to exist at the Effective Time, and no consideration

                         (iii) each share of the common stock, $0.001 par value

provided, however, that:

                              (A) if the Parent Average Stock Price is less than
$14.00, then each outstanding share of Company Common Stock shall be converted
into the number of shares of Parent Common Stock determined by dividing $7.00 by
the Parent Average Stock Price, and

                              (B) if the Parent Average Stock Price is greater
than $20.00, then each outstanding share of Company Common Stock shall be
converted into the number of shares of Parent Common Stock determined by
dividing $10.00 by the Parent Average Stock Price.

                    (b) The fraction of a share of Parent Common Stock into
which each outstanding share of Company Common Stock is to be converted pursuant
to Section 1.5(a)(iv) (as such fraction may be adjusted from time to time in
accordance with this Section 1.5(b)) is referred to as the "EXCHANGE RATIO."
If, between the date of this Agreement and the Effective Time, the outstanding
shares of Company Common Stock or Parent Common Stock are changed into a
different number or class of shares by reason of any stock split, division or
subdivision of shares, stock dividend, reverse stock split, consolidation of
shares, reclassification, recapitalization or other similar transaction, then
the Exchange Ratio shall be appropriately adjusted. For example, if one share of
Parent Common Stock, as constituted on the date hereof, is reconstituted into
one share of Class A Common Stock and one-half of a share of Class B Common
Stock and the Exchange Ratio is 0.5 such that 2 shares of Company Common Stock
would convert into 1 share of Parent Common Stock as constituted on the date
hereof, then with respect to the conversion into the reconstituted shares, 2
shares of Company Common Stock would be converted into 1 share of Class A Common
Stock and 1/2 share of Class B Common Stock.

                    (c) If any shares of Company Common Stock outstanding
immediately prior to the Effective Time are unvested or are subject to a
repurchase option, risk of forfeiture or other condition under any applicable
restricted stock purchase agreement or other agreement with the Company or under
which the Company has any rights, then (unless such condition terminates by
virtue of the Merger pursuant to the express term of such agreement) the shares
of Parent Common Stock issued in exchange for such shares of Company Common
Stock will also be unvested and subject to the same repurchase option, risk of
forfeiture or other condition, and the certificates representing such shares of
Parent Common Stock may accordingly be marked with appropriate legends. The
Company shall take all action that may be necessary to ensure that, from and
after the Effective Time, Parent is entitled to exercise any such repurchase
option or other right set forth in any such restricted stock purchase agreement
or other agreement.

                    (d) No fractional shares of Parent Common Stock shall be
issued in connection with the Merger, and no certificates or scrip for any such
fractional shares shall be issued. Any holder of Company Common Stock who would
otherwise be entitled to receive a fraction of a share of Parent Common Stock
(after aggregating all fractional shares of Parent Common Stock issuable to such
holder) shall, in lieu of such fraction of a share and upon surrender of such
holder's Company Stock Certificate(s) (as defined in Section 1.6), be paid in
cash the dollar amount (rounded to the nearest whole cent), without interest,
determined by multiplying such fraction by the closing price of a share of
Parent Common Stock on Nasdaq on the Effective Date (or, if such date is not a
trading day, then the trading day immediately preceding the Effective Date).

             1.6 STOCK OPTIONS. At the Effective Time, all Company Options (as
defined in Section 2.3(b)) shall be assumed by Parent in accordance with Section
5.4.

             1.7 CLOSING OF THE COMPANY'S TRANSFER BOOKS. At the Effective Time:
(a) all shares of Company Common Stock outstanding immediately prior to the
Effective Time shall automatically be canceled and retired and shall cease to
exist, and all holders of certificates representing shares of Company Common
Stock that were outstanding immediately prior to the Effective Time shall cease
to have any rights as stockholders of the Company; and (b) the stock transfer
books of the Company shall be closed with respect to all shares of Company
Common Stock outstanding immediately prior to the Effective Time. No further
transfer of any such shares of Company Common Stock shall be made on such stock
transfer books after the Effective Time. If, after the Effective Time, a valid
certificate previously representing any shares of Company Common Stock (a
"COMPANY STOCK CERTIFICATE") IS presented to the Exchange Agent (as defined in
Section 1.8) or to the Surviving Corporation or Parent, such Company Stock
Certificate shall be canceled and shall be exchanged as provided in Section 1.8.

             1.8 EXCHANGE OF CERTIFICATES.

                    (a) Harris Trust and Savings Bank or such other reputable
bank or trust company selected by Parent prior to the Closing Date shall act as
exchange agent in the Merger (the "EXCHANGE AGENT"). Promptly after the
Effective Time, Parent shall deposit with the Exchange Agent (i) certificates
representing the shares of Parent Common Stock issuable pursuant to this Section
1, and (ii) cash sufficient to make payments in lieu of fractional shares in
accordance with Section 1.5(d). The shares of Parent Common Stock and cash
amounts so deposited with the Exchange Agent, together with any dividends or
distributions received by the Exchange Agent with respect to such shares, are
referred to collectively as the "EXCHANGE FUND."

                    (b) As soon as practicable after the Effective Time, the
Exchange Agent will mail to the record holders of Company Stock Certificates (i)
a letter of transmittal in customary form and containing such provisions as
Parent may reasonably specify (including a provision confirming that delivery of
Company Stock Certificates shall be effected, and risk of loss and title to
Company Stock Certificates shall pass, only upon delivery of such Company Stock
Certificates to the Exchange Agent), and (ii) instructions for use in effecting
the surrender of Company Stock Certificates in exchange for certificates
representing Parent Common Stock. Upon surrender of a Company Stock Certificate
to the Exchange Agent for exchange, together



                                       4.
<PAGE>   10

with a duly executed letter of transmittal and such other documents as may be
reasonably required by the Exchange Agent or Parent, (1) the holder of such
Company Stock Certificate shall be entitled to receive in exchange therefor a
certificate representing the number of whole shares of Parent Common Stock that
such holder has the right to receive pursuant to the provisions of Section 1.5
(and cash in lieu of any fractional share of Parent Common Stock), and (2) the
Company Stock Certificate so surrendered shall be canceled. Until surrendered as
contemplated by this Section 1.8(b), each Company Stock Certificate shall be
deemed, from and after the Effective Time, to represent only the right to
receive shares of Parent Common Stock (and cash in lieu of any fractional share
of Parent Common Stock) as contemplated by Section 1.5. If any Company Stock
Certificate shall have been lost, stolen or destroyed, Parent may, in its
discretion and as a condition precedent to the issuance of any certificate
representing Parent Common Stock, require the owner of such lost, stolen or
destroyed Company Stock Certificate to provide an appropriate affidavit and to
deliver a bond (in such sum as Parent may reasonably direct) as indemnity
against any claim that may be made against the Exchange Agent, Parent or the
Surviving Corporation with respect to such Company Stock Certificate.

                    (c) No dividends or other distributions declared or made
with respect to Parent Common Stock with a record date after the Effective Time
shall be paid to the holder of any unsurrendered Company Stock Certificate with
respect to the shares of Parent Common Stock which such holder has the right to
receive upon surrender thereof until such holder surrenders such Company Stock
Certificate in accordance with this Section 1.8 (at which time such holder shall
be entitled, subject to the effect of applicable escheat or similar laws, to
receive all such dividends and distributions, without interest).

                    (d) Any portion of the Exchange Fund that remains
undistributed to holders of Company Stock Certificates as of the date 180 days
after the date on which the Merger becomes effective shall be delivered to
Parent upon demand, and any holders of Company Stock Certificates who have not
theretofore surrendered their Company Stock Certificates in accordance with this
Section 1.8 shall thereafter look only to Parent for satisfaction of their
claims for Parent Common Stock, cash in lieu of fractional shares of Parent
Common Stock and any dividends or distributions with respect to Parent Common
Stock.

                    (e) Neither Parent nor the Surviving Corporation shall be
liable to any holder or former holder of Company Common Stock or to any other
Person with respect to any shares of Parent Common Stock (or dividends or
distributions with respect thereto), or for any cash amounts, delivered to any
public official pursuant to any applicable abandoned property law, escheat law
or similar Legal Requirement.

             1.9 DISSENTING SHARES. Notwithstanding anything to the contrary
contained in this Agreement, any shares of Company Common Stock outstanding
immediately prior to the Effective Time that are or may become "dissenting
shares" within the meaning of Section 1300(b) of the California Corporations
Code (the "CCC") if such section is applicable to this Merger, ("DISSENTING
SHARES") shall not be converted into or represent the right to receive Parent
Common Stock in accordance with Section 1.5(a)(iii) (or cash in lieu of
fractional shares in accordance with Section 1.5(d)), and each holder of
Dissenting Shares shall be entitled only to such rights as may be granted to
such holder under Chapter 13 of the CCC. From and after the Effective Time, a
holder of Dissenting Shares shall not be entitled to exercise any of the voting



                                       5.
<PAGE>   11

rights or other rights of a shareholder of the Surviving Corporation. If any
holder of Dissenting Shares shall fail to assert or perfect, or shall waive,
rescind, withdraw or otherwise lose, such holder's right to dissent and obtain
payment under Chapter 13 of the CCC, then such shares shall automatically be
converted into and shall represent only the right to receive (upon the surrender
of Company Stock Certificate(s) previously representing such shares) Parent
Common Stock in accordance with Section 1.5(a)(iii) (and cash in lieu of any
fractional share in accordance with Section 1.5(d)) and any dividends or other
distributions to which such holder is entitled in accordance with Section 1.8.

             1.10 TAX CONSEQUENCES. For federal income tax purposes, the Merger
is intended to constitute a reorganization within the meaning of Section 368 of
the Code. The parties to this Agreement hereby adopt this Agreement as a "plan
of reorganization" within the meaning of Sections 1.368-2(g) and 1.368-3(a) of
the United States Treasury Regulations.

             1.11 ACCOUNTING CONSEQUENCES. For financial reporting purposes, the
Merger is intended to be accounted for as a purchase.

             1.12 FURTHER ACTION. If, at any time after the Effective Time, any
further action is determined by Parent to be necessary or desirable to carry out
the purposes of this Agreement or to vest the Surviving Corporation with full
right, title and possession of and to all rights and property of Merger Sub and
the Company, the officers and directors of the Surviving Corporation and Parent
shall be fully authorized (in the name of Merger Sub, in the name of the Company
and otherwise) to take such action.

        SECTION 2. REPRESENTATIONS AND WARRANTIES OF THE COMPANY

        The Company represents and warrants to Parent and Merger Sub that,
except as set forth in the disclosure schedule and that has been delivered by
the Company to Parent on the date of this Agreement (the "COMPANY DISCLOSURE
SCHEDULE"):

             2.1 DUE ORGANIZATION; SUBSIDIARIES; ETC.

                    (a) The Company has no Subsidiaries and the Company does not
own any capital stock of, or any equity interest of any nature in, any other
Entity, other than the Entities identified in Part 2.1(a)(ii) of the Company
Disclosure Schedule. The Company has not agreed and is not obligated to make,
nor bound by any Contract under which it may become obligated to make, any
future investment in or capital contribution to any other Entity. The Company
has not, at any time, been a general partner of, or has otherwise been liable
for any of the debts or other obligations of, any general partnership, limited
partnership or other Entity.

                    (b) The Company is a corporation duly organized, validly
existing and in good standing under the laws of the State of Delaware and has
all necessary power and authority: (i) to conduct its business in the manner in
which its business is currently being conducted; (ii) to own and use its assets
in the manner in which its assets are currently owned and used; and (iii) to
perform its obligations under all Contracts by which it is bound.

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



                                       6.
<PAGE>   12

requires such qualification and where the failure to be so qualified would
reasonably be expected to have a Material Adverse Effect on the Company.

delivered to Parent accurate and complete copies of its certificate of
incorporation, bylaws and other charter and organizational documents, including

as of the date of this Agreement); and (ii) 5,000,000 shares of Preferred Stock,
$0.01 par value per share, of which no shares have been issued or are
outstanding. The Company does not hold any shares of its capital stock in its

issued in compliance with all applicable Federal and state securities laws and
other applicable Legal Requirements and all requirements set forth in applicable

any similar right; and (ii) there is no Company Contract relating to the voting
or registration of, or restricting any Person from purchasing, selling, pledging
or otherwise disposing of (or granting any option or similar right with respect
to), any shares of Company Common Stock. Upon consummation of the Merger, (A)
the shares of Parent Common Stock issued in exchange for any shares of Company
Common Stock that are subject to a Contract pursuant to which the Company has
the right to repurchase, redeem or otherwise reacquire any shares of Company
Common Stock will, without any further act of Parent, the Company or any other
Person, become subject to the restrictions, conditions and other provisions
contained in such Contract, and (B) Parent will automatically succeed to and
become entitled to exercise the Company's rights and remedies under such
Contract. The Company is not under any obligation, or is bound by any Contract
pursuant to which it may become obligated, to repurchase, redeem or otherwise
acquire any outstanding shares of Company Common Stock.

"OPTION PLANS"); and (ii) 45,567 shares of Company Common Stock are reserved for
future issuance pursuant to the Company's 1992 Employee Stock Purchase Plan (the
"ESPP"). (Stock options granted by the Company pursuant to the Company's stock
option plans that are currently in effect or that have been in effect and
otherwise are referred to in this Agreement as "COMPANY OPTIONS.") There are no
Company Options other than Company Options outstanding under the Option Plans.

2.3(b)(i) of the Company Disclosure Schedule. The Company has delivered to
Parent accurate and complete copies of all Option Plans pursuant to which the
Company has ever granted stock options, and the forms of all stock option
agreements evidencing such options. Except as set forth in Part 2.3(b)(ii) of
the Company Disclosure Schedule, there are no commitments or agreements of any
character to which the Company is bound obligating the Company to accelerate the
vesting of any Company Option.

                    (c) Except for the Rights and as set forth in Part 2.3(b) of
the Company Disclosure Schedule, there is no: (i) outstanding subscription,
option, call, warrant or right (whether or not currently exercisable) to acquire
any shares of the capital stock or other securities of the Company; (ii)
outstanding security, instrument or obligation that is or may become convertible
into or exchangeable for any shares of the capital stock or other securities of
the Company; (iii) stockholder rights plan (or similar plan commonly referred to
as a "poison pill") or Contract under which the Company is or may become
obligated to sell or otherwise issue any shares of its capital stock or any
other securities; or (iv) condition or circumstance that may give rise to or

notice or lapse of time, or both, would constitute a default) that would result
in a Material Adverse Effect on the Company. The Company has valid leasehold
interests in the items listed in Parts 2.8(a) and 2.8(b) of the Company

the Company Disclosure Schedule identifies and provides a brief description of,

                         (ii) To the best of the knowledge of the Company, all

is substantially identical to the form of Confidential Non-Disclosure Agreement
previously delivered to Parent.

                    (c) To the best of the knowledge of the Company: (i) all
patents, trademarks, service marks and copyrights held by the Company are valid,
enforceable and subsisting; (ii) none of the Company Proprietary Assets and no

any Company Source Code. No event has occurred, and no circumstance or condition
exists, that (with or without notice or lapse of time) will, or could reasonably
be expected to, result in the disclosure or delivery to any Person of any
Company Source Code. Part 2.10(a)(xii) of the Company Disclosure Schedule
identifies each Contract pursuant to which the Company has deposited or is
required to deposit with an escrowholder or any other Person any Company Source
Code, and further describes whether the execution of this Agreement or the
consummation of any of the transactions contemplated hereby could reasonably be
expected to result in the release or disclosure of any Company Source Code. Part
2.9(e)(ii) of the Company Disclosure Schedule lists the Company Source Code or
portions thereof which the Company plans to annotate with comments in a manner

material respects to design specifications and documented performance criteria;
and (iii) there has not been any claim by any customer or other Person alleging

been licensed or otherwise made available by the Company to any Person) does not
conform in all material respects with any specification, documentation,
performance standard, or documented performance criteria made or provided by or
on behalf of the Company, and, to the best of the knowledge of the Company,
there is no basis for any such claim. To the best of the knowledge of the
Company, the Company has established adequate reserves on the Company Balance
Sheet to cover all costs associated with any obligations that the Company may
have with respect to the correction or repair of programming errors or other
defects in the Company Proprietary Assets.

Except as set forth in Part 2.9(g)(ii) of the Company Disclosure Schedule, each

respect to a computer, computer program or other item of software, that such
computer, computer program or other items of software will properly perform date
sensitive functions before, during and after the Year 2000. Part 2.9(g)(iv) of
the Company Disclosure Schedule sets forth a brief description of the Year 2000
Compliant and non-Year 2000 Compliant systems, and a brief description of the
actions taken to date, and proposed to be taken, with respect to all Company
utilized systems.

                    (h) Except with respect to demonstration or trial copies, no
product, system, program or software module designed, developed, sold, licensed
or otherwise made available by the Company to any Person contains any "back
door," "time bomb," "Trojan horse," "worm," "drop dead device," "virus" or other
software routines or hardware components designed to permit unauthorized access
or to disable or erase software, hardware or data without the consent of the
user.

Disclosure Schedule, each SNAP product, SNAP system, SNAP program, SNAP
Proprietary Asset or other

similar defect that would not adversely affect in any material respect such SNAP
product, SNAP system, SNAP program, SNAP Company Proprietary Asset or other SNAP
asset (or the operation or performance thereof). Part 2.9(i) of the Company
Disclosure Schedule contains an accurate and complete copy of the most recent
"bug list" with respect to each SNAP product and SNAP product under development
or pre-release testing.

                    (j) Except as set forth in Part 2.90(j) of the Company

asset (other than SNAP products, SNAP systems, SNAP programs, SNAP Proprietary
Assets and other SNAP assets) designed, developed, manufactured, assembled,
sold, installed, repaired, licensed or otherwise made available by the Company
to any Person was free of any bug, virus, design defect or other defect or
deficiency at the time it was sold or otherwise made available, other than any

respect such product, system, program, Company Proprietary Asset or other asset

                      (e) There is no agreement, plan, arrangement or other
Contract covering any employee or independent contractor or former employee or
independent contractor of the Company that, considered individually or
considered collectively with any other such Contracts, will, or could reasonably
be expected to, give rise directly or indirectly to the payment of any amount
that would not be deductible pursuant to Section 280G of the Code (or any
comparable provision under state or foreign Tax laws). The Company is not, and
has never been, a party to or bound by any tax indemnity agreement, tax sharing
agreement, tax allocation agreement or similar Contract.

               2.17   EMPLOYEE AND LABOR MATTERS; BENEFIT PLANS.

                      (a) Part 2.17(a) of the Company Disclosure Schedule

benefits, supplemental unemployment benefits, profit-sharing, pension,
retirement or other employee benefit plan, program or agreement maintained,
sponsored, contributed to or required to be contributed to by the Company for
the benefit of any current or former employee of the Company. (All plans,
programs and agreements of the type referred to in the prior sentence are
referred to in this Agreement as the "PLANS.") None of the Plans required to be
identified in the Company Disclosure Schedule is a multiemployer plan (within
the meaning of Section 3(37) of ERISA).

                      (b) Except as set forth in Part 2.17(a) of the Company

Income Security Act of 1974, as amended ("ERISA") or any similar pension benefit
plan under the laws of any foreign jurisdiction, whether or not excluded from
coverage under specific Titles or Subtitles of ERISA, for the benefit of any
current or former employee or director of the Company (a "PENSION PLAN"). None
of the Pension Plans required to be identified in Part 2.17(a) of the Company
Disclosure Schedule is subject to Title IV of ERISA or Section 412 of the Code.



                                      20.
<PAGE>   26

                      (c) Except as set forth in Part 2.17(a) of the Company
Disclosure Schedule, the Company does not maintain, sponsor or contribute to
any: (i) employee welfare benefit plan (as defined in Section 3(1) of ERISA) or
any similar welfare benefit plan under the laws of any foreign jurisdiction,
whether or not excluded from coverage under specific Titles or Subtitles of
ERISA, for the benefit of any current or former employee or director of the
Company (a "WELFARE PLAN"), or (ii) self-funded medical, dental or other similar
Plan.

                      (d) With respect to each Plan, the Company has delivered
to Parent: (i) an accurate and complete copy of such Plan (including all
amendments thereto); (ii) an accurate and complete copy of the annual report, if
required under ERISA, with respect to such Plan for each of the last two years;
(iii) an accurate and complete copy of the most recent summary plan description,
together with each summary of material modifications, if required under ERISA,
with respect to such Plan, (iv) if such Plan is funded through a trust or any
third party funding vehicle, an accurate and complete copy of the trust or other
funding agreement (including all amendments thereto) and accurate and complete
copies of the most recent financial statements thereof; (v) accurate and
complete copies of all Contracts relating to such Plan, including service
provider agreements, insurance contracts, minimum premium contracts, stop-loss
agreements, investment management agreements, subscription and participation
agreements and recordkeeping agreements; and (vi) an accurate and complete copy
of the most recent determination letter received from the Internal Revenue
Service with respect to such Plan (if such Plan is intended to be qualified
under Section 401(a) of the Code).

                      (e) Except as set forth in Part 2.16(e) of the Company
Disclosure Schedule, the Company is not and has never been required to be
treated as a single employer with any other Person under Section 4001(b)(1) of
ERISA or Section 414(b), (c), (m) or (o) of the Code. The Company has never been
a member of an "affiliated service group" within the meaning of Section 414(m)
of the Code. The Company has never made a complete or partial withdrawal from a
multiemployer plan, as such term is defined in Section 3(37) of ERISA, resulting
in "withdrawal liability," as such term is defined in Section 4201 of ERISA
(without regard to any subsequent reduction or waiver of such liability under
either Section 4207 or 4208 of ERISA).

                      (f) The Company has no plan or commitment to create any
additional Pension Plan or Welfare Plan, or to modify or change any existing
Welfare Plan or Pension Plan (other than to comply with applicable law) in a
manner that would affect any current or former employee or director of the
Company.

                      (g) No Plan provides death, medical or health benefits
(whether or not insured) with respect to any current or former employee or
director of the Company after any termination of service of such employee or
director (other than benefit coverage mandated by applicable law, including
coverage provided pursuant to Section 4980B of the Code).

                      (h) With respect to any Plan constituting a group health
plan within the meaning of Section 4980B(g)(2) of the Code, the provisions of
Section 4980B of the Code ("COBRA") have been complied with in all material
respects. Part 2.17(h) of the Company Disclosure Schedule describes all
obligations of the Company under any of the provisions of COBRA.



                                      21.
<PAGE>   27

                      (i) Each of the Plans has been operated and administered
in all material respects in accordance with applicable Legal Requirements,
including ERISA, the Code and applicable foreign Legal Requirements.

                      (j) Each of the Plans intended to be qualified under
Section 401(a) of the Code has received a favorable determination letter as to
its qualification from the Internal Revenue Service, and nothing has occurred
that would adversely affect the ability of the Company to rely on each such
determination letter.

                      (k) Except as set forth in Part 2.17(k) of the Company
Disclosure Schedule, neither the execution, delivery or performance of this
Agreement, nor the consummation of the Merger or any of the other transactions
contemplated by this Agreement, will result in any bonus, golden parachute,
severance or other payment or obligation to any current or former employee or
director of the Company (whether or not under any Plan), or materially increase
the benefits payable or provided under any Plan, or result in any acceleration
of the time of payment, provision or vesting of any such benefits. Without
limiting the generality of the foregoing (and except as set forth in Part
2.17(k) of the Company Disclosure Schedule), the consummation of the Merger will
not result in the acceleration of vesting of any unvested Company Options.

                      (1) Part 2.17(1) of the Company Disclosure Schedule
identifies each employee of the Company as of the date of this Agreement, and
correctly reflects, in all material respects, the current salary and any other
compensation payable to such employee (including compensation payable pursuant
to bonus, deferred compensation or commission arrangements), such employee's
employer, date of hire and position and the principal office of such employee.
The Company is not a party to any collective bargaining contract or other
Contract with a labor union involving any of its employees. All of the employees
of the Company are "at will" employees.

                      (m) Part 2.17(m) of the Company Disclosure Schedule
identifies each employee of the Company who is not fully available to perform
work because of disability or other leave and sets forth the basis of such
disability or leave and the anticipated date of such employee's return to full
service.

                      (n) The Company is in compliance in all material respects
with all applicable Legal Requirements and Contracts relating to employment,
employment practices, wages, bonuses and terms and conditions of employment,
including employee compensation matters.

                      (o) The Company has good labor relations, and the Company
has no knowledge of any facts indicating that (i) the consummation of the Merger
or any of the other transactions contemplated by this Agreement will have a
material adverse effect on the labor relations of the Company, or (ii) as of the
date of this Agreement, any of the employees of the Company intend to terminate
his or her employment with the Company.

               2.18 ENVIRONMENTAL MATTERS. The Company is in compliance in all
material respects with all applicable Environmental Laws, which compliance
includes the possession by



                                      22.
<PAGE>   28

the Company of all permits and other Governmental Authorizations required under
applicable Environmental Laws, and compliance with the terms and conditions
thereof. The Company has not received any notice or other communication (in
writing or otherwise), whether from a Governmental Body, citizens group,
employee or otherwise, that alleges that the Company is not in compliance with
any Environmental Law, and, to the best of the knowledge of the Company, there
are no circumstances that may prevent or interfere with the compliance by the
Company with any Environmental Law in the future. To the best of the knowledge
of the Company, no current or prior owner of any property leased or controlled
by the Company has received any notice or other communication (in writing or
otherwise), whether from a Government Body, citizens group, employee or
otherwise, that alleges that such current or prior owner or the Company is not
in compliance with any Environmental Law. To the best of the Company's
knowledge, (a) all property that is leased to, controlled by or used by the
Company, and all surface water, groundwater and soil associated with or adjacent
to such property is free of any material environmental contamination of any
nature, (b) none of the property leased to, controlled by or used by the Company
contains any underground storage tanks, asbestos, equipment using PCBs,
underground injection wells, and (c) none of the property leased to, controlled
by or used by the Company contains any septic tanks in which process wastewater
or any Materials of Environmental Concern have been disposed. The Company has
never sent or transported, or arranged to send or transport, any Materials of
Environmental Concern to a site that, pursuant to any applicable Environmental
Law (i) has been placed on the "National Priorities List" of hazardous waste
sites or any similar state list, (ii) is otherwise designated or identified as a
potential site for remediation, cleanup, closure or other environmental remedial
activity, or (iii) is subject to a Legal Requirement to take "removal" or
"remedial" action as detailed in any applicable Environmental Law or to make
payment for the cost of cleaning up the site.

               2.19 INSURANCE. The Company has delivered to Parent a copy of
each material insurance policy and each self insurance program or arrangement
relating to the business, assets and operations of the Company. Each such
insurance policy is in full force and effect. Since January 1, 1996, the Company
has not received any notice or other communication regarding any actual or
possible (a) cancellation or invalidation of any such insurance policy, (b)
refusal of any coverage or rejection of any material claim under any insurance
policy, or (c) material adjustment in the amount of the premiums payable with
respect to any insurance policy. Except as set forth in Part 2.19 of the Company
Disclosure Schedule, there is no pending workers' compensation or other claim
under or based upon any insurance policy of the Company; and, to the best of the
knowledge of the Company, no event has occurred, and no condition or
circumstance exists, that might (with or without notice or lapse of time)
directly or indirectly give rise to or serve as a basis for any such claim.

               2.20 TRANSACTIONS WITH AFFILIATES. Except as set forth in the
Company SEC Reports, since the date of the Company's last proxy statement filed
with the SEC, no event has occurred that would be required to be reported by the
Company pursuant to Item 404 of Regulation S-K promulgated by the SEC. Part 2.20
of the Company Disclosure Schedule identifies each person who is (or who may be
deemed to be) an "affiliate" (as that term is used in Rule 145 under the
Securities Act) of the Company as of the date of this Agreement.

               2.21   LEGAL PROCEEDINGS; ORDERS.

                      (a) As of the date hereof, there is no pending Legal
Proceeding, and to the best of the knowledge of the Company, no Person has
threatened to commence any Legal Proceeding: (i) that involves the Company or
any of the assets owned or used by the Company; or (ii) that challenges, or that
may have the effect of preventing, delaying, making illegal or otherwise
interfering with, the Merger or any of the other transactions contemplated by
this Agreement. To the best of the knowledge of the Company, no event has
occurred, and no claim, dispute or other condition or circumstance exists, that
could reasonably be expected to, give rise to or serve as a basis for the
commencement of any such Legal Proceeding. To the best of the knowledge of the
Company, no event has occurred, and no claim, dispute or other circumstance or
condition exists, that will, or that could reasonably be expected to, cause or
provide a basis for a director, officer or other representative of the Company
to seek indemnification from, or commence a Legal Proceeding against or
involving, the Company.

                      (b) There is no material order, writ, injunction, judgment
or decree to which the Company, or any of the assets owned or used by the
Company, is subject. To the best of the knowledge of the Company, no officer or
key employee of the Company is subject to any order, writ, injunction, judgment
or decree that prohibits such officer or other employee from engaging in or
continuing any conduct, activity or practice relating to the business of the
Company.

               2.22 AUTHORITY; INAPPLICABILITY OF ANTI-TAKEOVER STATUTES;
BINDING NATURE OF AGREEMENT. The Company has the absolute and unrestricted
right, power and authority to enter into and to perform its obligations under
this Agreement. The board of directors of the Company (at a meeting duly called
and held) has (a) determined (pursuant to a unanimous vote of all members of the
board of directors of the Company) that the Merger is advisable and fair and in
the best interests of the Company and its stockholders, (b) authorized and
approved (pursuant to a unanimous vote of all members of the board of directors
of the Company) the execution, delivery and performance of this Agreement by the
Company and approved (pursuant to a unanimous vote of all members of the board
of directors of the Company) the Merger, (c) recommended (pursuant to a
unanimous vote of all members of the board of directors of the Company) the
approval of this Agreement and the Merger by the holders of Company Common Stock
and directed that this Agreement and the Merger be submitted for consideration
by the Company's stockholders at the Company Stockholders' Meeting (as defined
in Section 5.2), and (d) adopted (pursuant to a unanimous vote of all members of
the board of directors of the Company) a resolution having the effect of causing
the Company not to be subject to any state takeover law or similar Legal
Requirement that might otherwise apply to the Merger or any of the other
transactions contemplated by this Agreement. The Company is not subject to
Section 2115 of the California Corporations Code. This Agreement constitutes the
legal, valid and binding obligation of the Company, enforceable against the
Company in accordance with its terms, subject to (i) laws of general application
relating to bankruptcy, insolvency and the relief of debtors, and (ii) rules of
law governing specific performance, injunctive relief and other equitable
remedies.

               2.23 SECTION 203 OF THE DGCL NOT APPLICABLE; COMPANY RIGHTS PLAN.
As of the date hereof and at all times on or prior to the Effective Time, the

<PAGE>   30

business combinations contained in Section 203 of the DGCL are, and will be,
inapplicable to the execution, delivery and performance of this Agreement and to
the consummation of the Merger and the other transactions contemplated by this
Agreement. Prior to the execution of those certain Voting Agreements of even
date herewith between Parent and each of the Persons identified on Exhibit G
hereto, the board of directors of the Company approved said Voting Agreements
and the transactions contemplated thereby. The board of directors of Company has
taken all actions so that the Company Rights Plan has been amended to (i) render
the Rights Plan inapplicable to the Merger and the other transactions
contemplated by this Agreement, (ii) ensure that (x) none of Parent or its
subsidiaries is an Acquiring Person (as defined in the Company Rights Plan)
pursuant to the Company Rights Plan by virtue of the execution of this Agreement
or the consummation of the Merger or the other transactions contemplated hereby
and (y) a Distribution Date (as such term is defined in the Company Rights Plan)
does not occur by reason of the execution of this Agreement, the consummation of
the Merger, or the consummation of the transactions contemplated hereby, and
such amendment may not be further amended by Company without the prior consent
of Parent in its sole discretion.

               2.24 NO DISCUSSIONS. Neither the Company, nor any Representative
of the Company, (i) is, or has at any time since January 1, 1998 been, engaged,
directly or indirectly, in any discussions or negotiations with any Person
relating to any Acquisition Proposal, (ii) has solicited, initiated, encouraged
or induced, or provided any nonpublic information to any Person relating to any
Acquisition Proposal, or (iii) has received any Acquisition Proposal.

               2.25 VOTE REQUIRED. The affirmative vote of the holders of a
majority of the shares of Company Common Stock outstanding on the record date
for the Company Stockholders' Meeting (the "REQUIRED COMPANY STOCKHOLDER VOTE")
is the only vote of the holders of any class or series of the Company's capital
stock necessary to approve this Agreement, the Merger and the other transactions
contemplated by this Agreement.

               2.26 NON-CONTRAVENTION; CONSENTS. Neither (1) the execution,
delivery or performance of this Agreement or any of the other agreements
referred to in this Agreement, nor (2) the consummation of the Merger or any of
the other transactions contemplated by this Agreement, will (with or without
notice or lapse of time):

                      (a) contravene, conflict with or result in a violation of
(i) any of the provisions of the certificate of incorporation, bylaws or other
charter or organizational documents of the Company, or (ii) any resolution
adopted by the stockholders, the board of directors or any committee of the
board of directors of the Company;

                      (b) contravene, conflict with or result in a violation of,
or give any Governmental Body or other Person the right to challenge the Merger
or any of the other transactions contemplated by this Agreement or to exercise
any remedy or obtain any relief under, any Legal Requirement or any order, writ,
injunction, judgment or decree to which the Company, or any of the assets owned
or used by the Company, is subject;

                      (c) contravene, conflict with or result in a violation of
any of the terms or requirements of, or give any Governmental Body the right to
revoke, withdraw, suspend, cancel, terminate or modify, any Governmental
Authorization that is held by the Company or



                                      25.
<PAGE>   31

that otherwise relates to the business of the Company or to any of the assets
owned or used by the Company;

                      (d) contravene, conflict with or result in a violation or
breach of, or result in a default under, any provision of any Company Contract
that is or would constitute a Material Contract, or give any Person the right to
(i) declare a default or exercise any remedy under any such Company Contract,
(ii) a rebate, chargeback, penalty or change in delivery schedule under any such
Company Contract, (iii) accelerate the maturity or performance of any such
Company Contract, or (iv) cancel, terminate or modify any term of such Company
Contract;

                      (e) result in the imposition or creation of any
Encumbrance upon or with respect to any asset owned or used by the Company
(except for minor liens that will not, in any case or in the aggregate,
materially detract from the value of the assets subject thereto or materially
impair the operations of the Company); or

                      (f) result in, or increase the likelihood of, the
disclosure or delivery to any escrowholder or other Person of the Company Source
Code, or the transfer of any material asset of the Company to any Person.

Except as set forth on Section 2.26(f) of the Company Disclosure Schedule, or as
may be required by the Exchange Act, the DGCL, the HSR Act and the NASD Bylaws
(as they relate to the Form S-4 Registration Statement and the Prospectus/Proxy
Statement), the Company was not, is not and will not be required to make any
filing with or give any notice to, or to obtain any Consent from, any Person in
connection with (x) the execution, delivery or performance of this Agreement or
any of the other agreements referred to in this Agreement, or (y) the
consummation of the Merger or any of the other transactions contemplated by this
Agreement.

               2.27 FAIRNESS OPINION. The Company's board of directors has
received the opinion of Donaldson, Lufkin & Jenrette Securities Corporation
("DLJ"), financial advisor to the Company, to the effect that the consideration
to be received by the stockholders of the Company in the Merger is fair to the
stockholders of the Company from a financial point of view. The Company will
promptly furnish to Parent an accurate and complete copy of said written opinion
dated the date of this Agreement.

               2.28 FINANCIAL ADVISOR. Except for DLJ, no broker, finder or
investment banker is entitled to any brokerage, finder's or other fee or
commission in connection with the Merger or any of the other transactions
contemplated by this Agreement based upon arrangements made by or on behalf of
the Company. The total of all fees, commissions and other amounts that may
become payable to DLJ by the Company if the Merger is consummated have been
communicated to Parent and the amounts to be paid shall not exceed the amounts
so communicated. The Company has furnished to Parent accurate and complete
copies of all agreements under which any such fees, commissions or other amounts
have been paid to may become payable and all indemnification and other
agreements related to the engagement of DLJ.

and the Company's stockholders that may be required or reasonably requested in
connection with any action contemplated by this Section 5.1. If any event
relating to the Company occurs, or if the Company becomes aware of any

        5.2 COMPANY STOCKHOLDERS' MEETING.

                        (a) The Company shall take all action necessary under
all applicable Legal Requirements to call, give notice of, convene and hold a
meeting of the holders of Company Common Stock to consider, act upon and vote
upon the adoption and approval of this Agreement and the approval of the Merger
(the "COMPANY STOCKHOLDERS' MEETING"). The Company Stockholders' Meeting shall
not be held fewer than twelve trading days following the Parent stockholders'
meeting related to the tracking stock proposal (the "PARENT MEETING") and shall
not be held fewer than thirty (30) days after following the Reincorporation
Meeting, (unless Parent shall have provided its prior written consent to hold

Meeting) but will be held as promptly as practicable after the later to occur of
the (1) twelfth day following the Parent Meeting or (2) the thirtieth day
following the Reincorporation Meeting, and in any event within forty-five (45)
days after the latest of (A) the date the Form S-4 Registration Statement is
declared effective under the Securities Act, (B) the Parent Meeting or (C) the
Reincorporation Meeting; provided, however, that if the proxy materials for the

the date for the Company Stockholders' Meeting shall be set for as soon as
practicable thereafter and in any event no later than the latest of (1) October
31, 1999, (2) forty-


                                      37.
<PAGE>   43

five (45) days after the effective date of the Form S-4 Registration Statement,
or (3) forty-five (45) days after the Reincorporation Meeting; provided,
however, that notwithstanding anything to the contrary contained in this
Agreement, the Company may adjourn or postpone the Company Shareholders' Meeting
to the extent necessary to ensure that any necessary supplement or amendment to
the Joint Proxy Statement/Prospectus is provided to the Company's shareholders
in advance of a vote on the Merger and this Agreement or, if as of the time for
which Company Shareholders' Meeting is originally scheduled (as set forth in the
Joint Proxy Statement/Prospectus) there are insufficient shares of Company
Common Stock represented (either in person or by proxy) to constitute a quorum
necessary to conduct the business of the Company's Shareholders' Meeting. The
Company shall ensure that the Company Stockholders' Meeting is called, noticed,
convened, held and conducted, and that all proxies solicited in connection with
the Company Stockholders' Meeting are solicited, in compliance with all
applicable Legal Requirements. The Company's obligation to call, give notice of,
convene and hold the Company Stockholders' Meeting in accordance with this
Section 5.2(a) shall not be limited or otherwise affected by the commencement,
disclosure, announcement or submission of any Superior Offer or other
Acquisition Proposal, or by any withdrawal, amendment or modification of the
recommendation of the board of directors of the Company with respect to the
Merger.

                        (b) Subject to Section 5.2(c): (i) the board of
directors of the Company shall unanimously recommend that the Company's
stockholders vote in favor of and adopt and approve this Agreement and approve
the Merger at the Company Stockholders' Meeting; (ii) the Prospectus/Proxy
Statement shall include a statement to the effect that the board of directors of
the Company has unanimously recommended that the Company's stockholders vote in
favor of and adopt and approve this Agreement and approve the Merger at the

Company nor any committee thereof shall withdraw, amend or modify, or propose or
resolve to withdraw, amend or modify, in a manner adverse to Parent, the
unanimous recommendation of the board of directors of the Company that the
Company's stockholders vote in favor of and adopt and approve this Agreement and
approve the Merger. For purposes of this Agreement, said recommendation of the
board of directors of the Company shall be deemed to have been modified in a
manner adverse to Parent if said recommendation shall no longer be unanimous.

                        (c) Nothing in Section 5.2(b) shall prevent the board of
directors of the Company from withdrawing, amending or modifying its unanimous
recommendation in favor of the Merger at any time prior to the adoption and
approval of this Agreement by the Required Company Stockholder Vote if (i) a
Superior Offer is made to the Company and is not withdrawn, (ii) neither the
Company nor any of its Representatives shall have violated any of the
restrictions set forth in Section 4.3, (iii) the board of directors of the
Company concludes in good faith, based upon the advice of its outside counsel,
that, in light of such Superior Offer, the withdrawal, amendment or
modification of such recommendation is required in order for the board of
directors of the Company to comply with its fiduciary obligations to the
Company's stockholders under applicable law, (iv) the Company provides Parent
with at least 48 hours prior notice of any meeting of the Company's board of
directors at which such board of directors is expected to consider such Superior
Offer, and (v) the Company's board of directors does not withdraw, amend or
modify its unanimous recommendation in favor of the Merger for at least 72 hours
after the Company provides Parent with the name of the Person making such
Superior Offer and


                                      38.
<PAGE>   44

a copy of such Superior Offer. Nothing contained in this Section 5.2 shall limit
the Company's obligation to call, give notice of, convene and hold the Company
Stockholders' Meeting (regardless of whether the unanimous recommendation of the
board of directors of the Company shall have been withdrawn, amended or
modified).

                5.3 REGULATORY APPROVALS. Each party shall use all reasonable
efforts to file, as promptly as practicable after the date of this Agreement,
all notices, reports and other documents required to be filed by such party with
any Governmental Body with respect to the Merger and the other transactions
contemplated by this Agreement, and to submit promptly any additional
information requested by any such Governmental Body. Without limiting the
generality of the foregoing, the Company and Parent shall, promptly after the
date of this Agreement, prepare and file the notifications required under the
HSR Act in connection with the Merger. The Company and Parent shall respond as
promptly as practicable to (i) any inquiries or requests received from the
Federal Trade Commission or the Department of Justice for additional information
or documentation and (ii) any inquiries or requests received from any state
attorney general or other Governmental Body in connection with antitrust or
related matters. Each of the Company and Parent shall (1) give the other party
prompt notice of the commencement of any Legal Proceeding by or before any
Governmental Body with respect to the Merger or any of the other transactions
contemplated by this Agreement, (2) keep the other party informed as to the
status of any such Legal Proceeding, and (3) promptly inform the other party of
any communication to or from the Federal Trade Commission, the Department of
Justice or any other Governmental Body regarding the Merger. The Company and
Parent will consult and cooperate with one another, and will consider in good
faith the views of one another, in connection with any analysis, appearance,
presentation, memorandum, brief, argument, opinion or proposal made or submitted
in connection with any Legal Proceeding under or relating to the HSR Act or any
other federal or state antitrust or fair trade law. In addition, except as may
be prohibited by any Governmental Body or by any Legal Requirement, in
connection with any Legal Proceeding under or relating to the HSR Act or any
other federal or state antitrust or fair trade law or any other similar Legal
Proceeding, each of the Company and Parent will permit authorized
Representatives of the other party to be present at each meeting or conference
relating to any such Legal Proceeding and to have access to and be consulted in
connection with any document, opinion or proposal made or submitted to any
Governmental Body in connection with any such Legal Proceeding.

                5.4 STOCK OPTIONS.

                        (a) At the Effective Time, all rights with respect to
Company Common Stock under each Company Option then outstanding shall be
converted into and become rights with respect to Parent Common Stock, and Parent
shall assume each such Company Option in accordance with the terms (as in effect
as of the date of this Agreement) of the stock option plan under which it was
issued and the stock option agreement by which it is evidenced. From and after
the Effective Time, (i) each Company Option assumed by Parent may be exercised
solely for shares of Parent Common Stock, (ii) the number of shares of Parent
Common Stock subject to each such Company Option shall be equal to the number of
shares of Company Common Stock subject to such Company Option immediately prior
to the Effective Time multiplied by the Exchange Ratio, rounded down to the
nearest whole share, (iii) the per share exercise price under each such Company
Option shall be adjusted by dividing the per share


                                      39.
<PAGE>   45

exercise price under such Company Option by the Exchange Ratio and rounded up to
the nearest cent and (iv) any restriction on the exercise of any such Company
Option shall continue in full force and effect and the term, exercisability,
vesting schedule and other provisions of such Company Option shall otherwise
remain unchanged; provided, however, that each Company Option assumed by Parent
in accordance with this Section 5.4(a) shall, in accordance with its terms, be
subject to further adjustment as appropriate to reflect any stock split,
division or subdivision of shares, stock dividend, reverse stock split,
consolidation of shares, reclassification, recapitalization or other similar
transaction subsequent to the Effective Time. Parent shall file with the SEC,
promptly after the date on which the Merger becomes effective, a registration
statement on Form S-8 relating to the shares of Parent Common Stock issuable
with respect to the Company Options assumed by Parent in accordance with this
Section 5.4(a).

                        (b) The Company shall take all action that may be
necessary (under the plans pursuant to which Company Options are outstanding and
otherwise) to effectuate the provisions of this Section 5.4 and to ensure that,
from and after the Effective Time, holders of Company Options have no rights
with respect thereto other than those specifically provided in this Section 5.4.

                        (c) As of the Effective Time, the ESPP shall be
terminated. The rights of participants in the ESPP with respect to any offering
period then underway under the ESPP shall be determined by treating the last
business day prior to the Effective Time as the last day of such offering period
and by making such other pro-rata adjustments as may be necessary to reflect the
reduced offering period but otherwise treating such offering period as a fully
effective and completed offering period for all purposes of such Plan. Prior to
the Effective Time, the Company shall take all actions (including, if
appropriate, amending the terms of the ESPP) that are necessary to give effect
to the transactions contemplated by this Section 5.4(d).

        5.5 INDEMNIFICATION OF OFFICERS AND DIRECTORS.

                (a) All rights to indemnification existing in favor of those
Persons who are directors and officers of the Company as of the date of this
Agreement (the "Indemnified Persons") for acts and omissions occurring prior to
the Effective Time, as provided in the Company's Bylaws (as in effect as of the
date of this Agreement) and as provided in the indemnification agreements
between the Company and said Indemnified Persons (as in effect as of the date of
this Agreement), shall survive the Merger and shall be observed by the Surviving
Corporation and Parent to the fullest extent available under Delaware law for a
period of six years from the Effective Time.

                (b) From the Effective Time until the third anniversary of the
Effective Time, the Surviving Corporation or Parent shall maintain in effect,
for the benefit of the Indemnified Persons with respect to acts or omissions
occurring prior to the Effective Time, the existing policy of directors' and
officers' liability insurance maintained by the Company as of the date of this
Agreement (the "Existing Policy"); provided, however, that (i) the Surviving
Corporation or Parent may substitute for the Existing Policy a policy or
policies of comparable coverage, and (ii) the Surviving Corporation shall not be
required to pay an annual premium for the Existing Policy (or for any substitute
policies) in excess of 150% of the amount of the last annual premium paid by the
Company prior to the date of this Agreement for the Existing Policy


                                      40.
<PAGE>   46

(the "Premium Amount"). In the event any future annual premium for the Existing
Policy (or any substitute policies) exceeds the Premium Amount, the Surviving
Corporation or Parent shall be entitled to reduce the amount of coverage of the
Existing Policy (or any substitute policies) to the maximum amount of coverage
that can be obtained for a premium equal to the Premium Amount.

        5.6 ADDITIONAL AGREEMENTS.

                (a) Subject to Section 5.6(b), Parent and the Company shall use

this Agreement. Without limiting the generality of the foregoing, but subject to

connection with the Merger and the other transactions contemplated by this
Agreement, (ii) shall use its best efforts to obtain each Consent (if any)
required to be obtained (pursuant to any applicable Legal Requirement or
Contract, or otherwise) by such party in connection with the Merger or any of
the other transactions contemplated by this Agreement, and (iii) shall use its
best efforts to lift any restraint, injunction or other legal bar to the Merger.
The Company shall promptly deliver to Parent a copy of each such filing made,

Pre-Closing Period.

Effective Time (whether before or after approval of the Merger by the Required

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

                        (b) by either Parent or the Company if the Merger shall
not have been consummated by December 31, 1999 (unless the failure to consummate
the Merger is attributable to a failure on the part of the party seeking to
terminate this Agreement to perform any material obligation required to be
performed by such party at or prior to the Effective Time);

                        (c) by either Parent or the Company if a court of

the Merger;

                        (d) by either Parent or the Company if (i) the Company
Stockholders' Meeting shall have been held and (ii) this Agreement and the
Merger shall not have been approved at such meeting by the Required Company
Stockholder Vote; provided, however, that the Company shall not be permitted to
terminate this Agreement pursuant to this Section 8.1(d) if the failure to
obtain the Required Company Stockholder Vote shall have been caused by the
action or failure to act of the Company and such action or failure to act
constitutes a material breach by the Company of this Agreement and unless the
Company shall have made all payments required to be made to Parent pursuant to
Section 8.3(b);

                        (e) by Parent (at any time prior to the adoption and
approval of this Agreement and the Merger by the Required Company Stockholder
Vote) if a Triggering Event shall have occurred;

                        (f) by Parent if any of the Company's representations
and warranties contained in this Agreement shall have been inaccurate as of the
date of this Agreement or shall have become inaccurate as of any subsequent date
(as if made on such subsequent date), or if any of the Company's covenants
contained in this Agreement shall have been breached in any respect, in either
case such that any of the conditions set forth in sections 6.1 or 6.2 would not
be satisfied as of the time such representation or warranty was or shall have
become inaccurate or as of the time of such breach; provided, however, that
Parent may not terminate this Agreement under this Section 8.1(f) on account of
an inaccuracy in the Company's representations and warranties that is curable by
the Company or on account of a breach of a covenant by the Company that is
curable by the Company unless the Company fails to cure such inaccuracy or
breach within 30 days after receiving written notice from Parent of such
inaccuracy or breach; or


                                      47.
<PAGE>   53

                        (g) by the Company if any of Parent's representations
and warranties contained in this Agreement shall have been inaccurate as of the
date of this Agreement or shall have become inaccurate as of any subsequent date
(as if made on such subsequent date), or if any of Parent's covenants contained
in this Agreement shall have been breached in any respect, in either case such
that any of the conditions set forth in Sections 7.1 or 7.2 would not be
satisfied as of the time such representation or warranty was or shall have
become inaccurate or as of the time of such breach; provided, however, that the
Company may not terminate this Agreement under this Section 8.1(g) on account
of an inaccuracy in Parent's representations and warranties that is curable by
Parent or on account of a breach of a covenant by Parent that is curable by
Parent unless Parent fails to cure such inaccuracy or breach within 30 days
after receiving written notice from the Company of such inaccuracy or breach.

                8.2 EFFECT OF TERMINATION. In the event of the termination of
this Agreement as provided in Section 8.1, this Agreement shall be of no further
force or effect; provided, however, that (i) this Section 8.2, Section 8.3 and
Section 9 shall survive the termination of this Agreement and shall remain in
full force and effect, and (ii) the termination of this Agreement shall not
relieve any party from any liability for any intentional or willful inaccuracy
in or intentional or willful breach of any representation, warranty or covenant
contained in this Agreement.

                8.3 EXPENSES; TERMINATION FEES.

                        (a) Except as set forth in this Section 8.3, all fees
and expenses incurred in connection with this Agreement and the transactions
contemplated by this Agreement shall be paid by the party incurring such
expenses, whether or not the Merger is consummated; provided, however, that
Parent and the Company shall share equally all fees and expenses, other than
attorneys' fees, incurred in connection with the filing, printing and mailing of
the Form S-4 Registration Statement and the Prospectus/Proxy Statement and any
amendments or supplements thereto and (B) the filing of the premerger
notification and report forms relating to the Merger under the HSR Act.

                        (b) If (i) this Agreement is terminated by Parent or the
Company pursuant to Section 8.1(d) and (A) a Company Acquisition is consummated
or (B) a proposed Company Acquisition is publicly announced, in either case at
any time prior to the first anniversary of the date of this Agreement, or (ii)
this Agreement is terminated by Parent pursuant to Section 8.1(e), then, in
either such case, the Company shall pay to Parent, in cash at the time specified
in the next sentence, a nonrefundable fee in the amount of $4,550,000. In the
case of termination of this Agreement by the Company pursuant to Section 8.1(d),
the fee referred to in the preceding sentence shall be paid by the Company
contemporaneously with the earlier of the consummation of such Company
Acquisition or such announcement regarding a proposed Company Acquisition, and

this Agreement, shall operate as a waiver of such power, right, privilege or
remedy; and no single or partial exercise of any such power, right, privilege or
remedy shall preclude any other or further exercise thereof or of any other
power, right, privilege or remedy.

                        (b) Neither party shall be deemed to have waived any
claim arising out of this Agreement, or any power, right, privilege or remedy
under this Agreement, unless the waiver of such claim, power, right, privilege
or remedy is expressly set forth in a written instrument duly executed and
delivered on behalf of such party; and any such waiver shall not be applicable

shall be enforceable by and inure solely to the benefit of, the parties hereto
and their respective successors and assigns; provided, however, that neither
this Agreement nor any of the Company's rights hereunder may be assigned by the
Company without the prior written consent of Parent, and any attempted
