     A. Parent and the Company each have determined that a business combination

Merger upon the terms and subject to the conditions set forth in this Agreement,
and (ii) determined to recommend that the stockholders of the Company adopt and
approve this Agreement and approve the Merger.

     D. It is intended that, for federal income tax purposes, the Merger shall

                     CONVERSION AND EXCHANGE OF SECURITIES

     2.1  Merger Sub Stock. At the Effective Time, each share of common stock of
Merger Sub outstanding immediately prior to the Effective Time shall be
converted into and exchanged for one validly issued, fully paid and
non-assessable share of common stock of the Surviving Corporation. Each
certificate evidencing ownership of shares of Merger Sub common stock shall
continue to evidence ownership of such shares of capital stock of the Surviving
Corporation.

     2.2  Company Stock.

          (a) Subject to Section 2.3(e), at the Effective Time, each outstanding
     share of common stock of the Company, par value $.001 per share (the
     "Company Common Stock"), other than any shares of Company common stock to
     be cancelled pursuant to Section 2.2(c) below shall, by virtue of the
     Merger and without any action on the part of the holder thereof, be
     cancelled and extinguished and automatically converted into the right to
     receive 0.4765 shares of common stock of the Parent, par value $.01 per
     share (the "Parent Common Stock") (such ratio, as adjusted pursuant to
     Section 2.4 below, being defined herein as the "Exchange Ratio").

          (b) As a result of the Merger and without any action on the part of
     the holder thereof, at the Effective Time, all shares of Company Common
     Stock outstanding immediately prior to the Effective Time shall cease to be
     outstanding and shall cease to exist, and each holder of shares of Company
     Common Stock shall thereafter cease to have any rights with respect to such
     shares of Company Common Stock, except the right to receive, without
     interest, the consideration contemplated by Section 2.2(a) and cash in lieu
     of fractional shares in accordance with Sections 2.3(c) and 2.3(e) upon the
     surrender of a certificate (a "Certificate") representing such shares of
     Company Common Stock.

          (c) Each share of Company Common Stock held in the Company's treasury
     at the Effective Time, and each share of Company Common Stock that is owned
     by Parent or any Parent Subsidiary (as defined in Section 4.1) at the
     Effective Time, shall, by virtue of the Merger, cease to be outstanding and
     shall be canceled and retired and shall cease to exist without payment of
     any consideration thereof.
                                       2


<PAGE>   3

          (d) As of the Effective Time, each outstanding option to purchase
     capital stock of the Company (the "Company Options"), whether or not
     exercisable and whether or not vested, under any plan or arrangement of the
     Company providing for the grant of options to purchase shares of Company
     Common Stock (collectively, the "Company Stock Option Plans"), shall be
     converted into an option to purchase Parent Common Stock. Each Company
     Option so converted shall be subject to the same terms and conditions as
     under the applicable Company Stock Option Plan immediately prior to the
     Effective Time and the applicable grant instrument issued thereunder
     (including, without limitation, any repurchase rights or vesting
     provisions), except that (A) each such Company Option shall be exercisable
     (or will become exercisable in accordance with its terms) for that number
     and whole shares of Parent Common Stock (rounded down to the nearest whole
     share) equal to the product of the number of shares of Company Common Stock
     that were issuable upon exercise of such Company Option immediately prior
     to the Effective Time multiplied by the Exchange Ratio, (B) the exercise
     price per share of Parent Common Stock shall be an amount equal to the
     quotient determined by dividing the exercise price per share of Company
     Common Stock subject to such Company Option in effect immediately prior to
     the Effective Time by the Exchange Ratio (the exercise price per share, as
     so determined, being rounded up to the nearest tenth of a cent), and (C)
     the vesting of certain Company Options as set forth on Section 3.25 of the
     Company Disclosure Schedule (as defined below) will be accelerated or
     become subject to subsequent acceleration pursuant to the terms of such
     Company Options as a result of the Merger, so long as such acceleration
     does not adversely affect Parent's ability to account for the Merger in
     accordance with the pooling of interests method of accounting under the
     requirements of APB No. 16.

          (e) It is the intention of the parties that the Company Options
     converted by Parent qualify following the Effective Time as incentive stock
     options as defined in Section 422 of the Code to the extent permitted under
     Section 422 of the Code and to the extent the Company Options qualified as
     incentive stock options prior to the Effective Time.

          (f) Parent shall, as soon as practicable after the Effective Time, but
     in no event later than 30 days after the Effective Time, file a
     registration statement on Form S-8 under the Securities Act of 1933 (the
     "Securities Act"), covering the shares of Parent Common Stock issuable upon
     the exercise of the Company Options converted under Section 2.2(d), and
     will maintain the effectiveness of such registration, and the current
     status of the prospectus contained therein, until the exercise or
     expiration of such converted Company Options.

     2.3  Exchange of Certificates Representing Company Common Stock.

          (a) As of the Effective Time, Parent shall deposit, or shall cause to
     be deposited, with a banking or other financial institution mutually
     acceptable to Parent and the Company (the "Exchange Agent"), for the
     benefit of the holders of shares of Company Common Stock, for exchange in
     accordance with this Article 2, certificates representing the shares of
     Parent Common Stock to be issued in connection with the Merger and cash in
     an amount equal to Parent's good faith estimate of the cash required to be
     paid to holders of shares of Company Common Stock in lieu of fractional
     shares expected to be payable in connection with the Merger (such cash and
     certificates for shares of Parent Common Stock, together with any dividends
     or distributions with respect thereto (relating to record dates for such
     dividends or distributions after the Effective Time), being hereinafter
     referred to as the "Exchange Fund") to be issued pursuant to Section 2.2
     and paid pursuant to this Section 2.3 in exchange for outstanding shares of
     Company Common Stock.

          (b) Promptly after the Effective Time, Parent shall cause the Exchange
     Agent to mail to each holder of record of shares of Company Common Stock
     (i) a letter of transmittal specifying that delivery shall be effected, and
     risk of loss and title to such shares of Company Common Stock shall pass,
     only upon delivery of the Certificates representing such shares to the
     Exchange Agent and which letter shall be in such form and have such other
     provisions as Parent may reasonably specify and (ii) instructions for use
     in effecting the surrender of Certificates in exchange for the
     consideration contemplated by Section 2.2 and this Section 2.3, including
     cash in lieu of fractional shares. Upon surrender of a Certificate for
     cancellation to the Exchange Agent together with such letter of
     transmittal, duly executed and completed

                                       3

<PAGE>   4

     in accordance with the instructions thereto, the holder of the shares
     represented by such Certificate shall be entitled to receive in exchange
     therefor (x) a certificate representing that number of whole shares of
     Parent Common Stock and (y) a check representing the amount of cash in lieu
     of fractional shares, if any, and unpaid dividends and distributions, if
     any, that such holder has the right to receive in respect of the
     Certificate surrendered pursuant to the provisions of this Article 2, after
     giving effect to any required withholding tax, and the shares represented
     by the Certificate so surrendered shall forthwith be canceled. No interest
     will be paid or accrued on the cash payable to holders of shares of Company
     Common Stock. In the event of a transfer of ownership of Company Common
     Stock that is not registered in the transfer records of the Company, a
     certificate representing the proper number of shares of Parent Common
     Stock, together with a check for the cash to be paid pursuant to Section
     2.3(b)(y) may be issued to such a transferee if the Certificate
     representing such Company Common Stock is presented to the Exchange Agent,
     accompanied by all documents required to evidence and effect such transfer
     and to evidence that any applicable stock transfer taxes have been paid.

          (c) Notwithstanding any other provisions of this Agreement, no
     dividends or other distributions declared after the Effective Time on
     Parent Common Stock shall be paid with respect to any shares of Company
     Common Stock represented by a Certificate until such Certificate is
     surrendered for exchange as provided herein. Following surrender of any
     such Certificate, there shall be paid to the holder of the certificates
     representing whole shares of Parent Common Stock issued in exchange
     therefor, without interest, (i) at the time of such surrender, the amount
     of dividends or other distributions with a record date after the Effective
     Time theretofore payable with respect to such whole shares of Parent Common
     Stock and not paid, less the amount of any withholding taxes which may be
     required thereon, and (ii) at the appropriate payment date, the amount of
     dividends or other distributions with a record date after the Effective
     Time but prior to surrender and a payment date subsequent to surrender
     payable with respect to such whole shares of Parent Common Stock, less the
     amount of any withholding taxes which may be required thereon.

          (d) At or after the Effective Time, there shall be no transfers on the
     stock transfer books of the Company of the shares of Company Common Stock
     which were outstanding immediately prior to the Effective Time. If, after
     the Effective Time, Certificates are presented to the Surviving
     Corporation, they shall be canceled and exchanged for certificates for
     shares of Parent Common Stock and cash deliverable in respect thereof
     pursuant to this Agreement in accordance with the procedures set forth in
     this Article 2. Certificates surrendered for exchange by any Affiliate (as
     defined in Section 5.9 hereof), shall not be exchanged until Parent has
     received a written agreement from such person as provided in Section 5.9.

          (e) No fractional shares of Parent Common Stock shall be issued
     pursuant hereto. In lieu of the issuance of any fractional share of Parent
     Common Stock, cash adjustments will be paid to holders in respect of any
     fractional share of Parent Common Stock that would otherwise be issuable,
     and the amount of such cash adjustment shall be equal to the product
     obtained by multiplying such stockholder's fractional share of Parent
     Common Stock that would otherwise be issuable by the average closing price
     per share of Parent Common Stock for the ten-day period ending two days
     before the Closing Date as reported by The Wall Street Journal (or, if not
     reported thereby, any other authoritative source).

          (f) Any portion of the Exchange Fund (including the proceeds of any
     investments thereof and any shares of Parent Common Stock) that remains
     unclaimed by the former stockholders of the Company one year after the
     Effective Time shall be delivered to Parent. Any former stockholders of the
     Company who have not theretofore complied with this Article 2 shall
     thereafter look only to Parent, and Parent shall comply with such requests,
     made in accordance with the terms of this Agreement, for payment of their
     shares of Parent Common Stock, cash and unpaid dividends and distributions
     on Parent Common Stock deliverable in respect of each share of Company
     Common Stock such stockholder holds as determined pursuant to this
     Agreement, in each case, without any interest thereon.

          (g) None of Parent, the Company, the Surviving Corporation, the
     Exchange Agent or any other person shall be liable (except to the extent
     provided by applicable law) to any former holder of shares of

                                       4


<PAGE>   5

     Company Common Stock for any amount properly delivered to a public official
     pursuant to applicable abandoned property, escheat or similar laws.

          (h) In the event any Certificate shall have been lost, stolen or
     destroyed, upon the making of an affidavit of that fact by the person
     claiming such Certificate to be lost, stolen or destroyed and the posting
     by such person of a bond in such amount as the Surviving Corporation may
     reasonably request as indemnity against any claim that may be made against
     it with respect to such Certificate, the Exchange Agent will issue in
     exchange for such lost, stolen or destroyed Certificate the shares of
     Parent Common Stock and cash deliverable in respect thereof pursuant to
     this Agreement.

     2.4  Adjustment of Exchange Ratio. In the event that, subsequent to the
date of this Agreement but prior to the Effective Time, the outstanding shares
of Parent Common Stock or Company Common Stock, respectively, shall have been
changed into a different number of shares or a different class as a result of a
stock split, reverse stock split, stock dividend, subdivision, reclassification,
combination, exchange, recapitalization or other similar transaction (or a
record date shall have been set for such purpose), the Exchange Ratio shall be
appropriately adjusted.

                                   ARTICLE 3

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

     Except as set forth in the disclosure schedule delivered prior to the
execution hereof to Parent (the "Company Disclosure Schedule"), the Company
represents and warrants to Parent as of the date of this Agreement as follows:

     3.1  Existence; Good Standing; Corporate Authority. The Company is a
corporation duly incorporated, validly existing and in good standing under the
laws of Delaware. The Company is duly licensed or qualified to do business as a
foreign corporation and is in good standing under the laws of any other
jurisdiction in which the character of the properties owned or leased by it or
in which the transaction of its business makes such qualification necessary,
except where the failure to be so qualified or to be in good standing would not
result in a Company Material Adverse Effect (as defined in Section 8.14 hereof).
The Company has all requisite corporate power and authority to own, operate and
lease its properties and carry on its business as now conducted, or as described
in the Company Reports, as reasonably contemplated in the future. The Company
has no Subsidiaries (as defined in Section 8.14) other than those Subsidiaries
set forth in Section 3.1 of the Company Disclosure Schedule (the "Company
Subsidiaries"). Each of the Company Subsidiaries is a corporation duly
organized, validly existing and in good standing, under the laws of the
jurisdictions in which such companies are incorporated. Neither the Company nor
any of the Company Subsidiaries is in violation of any order of any court,
governmental authority or arbitration board or tribunal, or any law, ordinance,
governmental rule or regulation to which the Company or any of the Company
Subsidiaries or any of their respective properties or assets is subject, other
than any violations that would not result in a Company Material Adverse Effect.

     3.2  Authorization, Validity and Effect of Agreements. The Company has the
requisite corporate power and authority to execute and deliver this Agreement
and all other agreements and documents to which it is a party contemplated
hereby and to perform its obligations hereunder. Subject only to the approval of
this Agreement and the Merger by the holders of a majority of the outstanding
shares of Company Common Stock, the consummation by the Company of the
transactions contemplated hereby have been unanimously approved by the Board of
Directors of the Company (the "Company Board") and duly authorized by all
requisite corporate action. This Agreement constitutes the valid and legally
binding obligation of the Company, enforceable in accordance with its terms,
subject to applicable bankruptcy, insolvency, moratorium or other similar laws
relating to creditors' rights and general principles of equity.

     3.3  Capitalization. The authorized capital stock of the Company consists
of 35,000,000 shares of Company Common Stock and 1,000,000 shares of preferred
stock of the Company (the "Company Preferred Stock"). As of July 12, 2000, there
were 13,417,034 shares of Company Common Stock and no shares of

                                       5


<PAGE>   6

Company Preferred Stock issued and outstanding. Since such date, no shares of
capital stock of Company have been issued, except shares of Company Common Stock
issued pursuant to the exercise of options outstanding under the Company Stock
Option Plans. As of July 12, 2000, options to acquire 1,905,833 shares of
Company Common Stock were outstanding pursuant to the terms of the Company Stock
Option Plans. The Company has no outstanding bonds, debentures, notes or other
obligations the holders of which have the right to vote (or which are
convertible into or exercisable for securities having the right to vote) on any
matter with respect to such securities. All issued and outstanding shares of
Company Common Stock are duly authorized, validly issued, fully paid,
nonassessable and free of preemptive rights, and were issued in compliance with
all applicable federal and state securities laws, rules and regulations. Other
than as set forth above, there were not, as of July 12, 2000, any existing
options, warrants, calls, subscriptions, convertible securities, or other
rights, agreements or commitments that obligate the Company or any of the
Company Subsidiaries to issue, transfer or sell any shares of capital stock of
the Company or any of the Company Subsidiaries or entitle any third party to
receive any capital stock of the Company or any of the Company Subsidiaries.
Section 3.3 of the Company's Disclosure Schedule lists all Company Options
outstanding as of July 12, 2000, and for each such Company Option the vesting
schedule through July 11, 2001. There are no voting trusts or other agreements
or understandings to which the Company is a party, nor, to the knowledge of the
Company, to which any stockholder of the Company is a party, with respect to the
voting of capital stock of the Company. The issuance of the Option Shares upon
exercise of the Company Option has been duly authorized by all requisite
corporate and stockholder action and, upon exercise of the Company Option, the
Option Shares will be validly issued, fully paid and non-assessable shares of
Company Common Stock.

     3.4  Subsidiaries. The Company owns directly or indirectly each of the
outstanding shares of capital stock of each of the Company Subsidiaries. Each of
the outstanding shares of capital stock of each of the Company Subsidiaries is
duly authorized, validly issued, fully paid and nonassessable, and is owned,
directly or indirectly, by the Company free and clear of all liens, pledges,
security interests, claims or other encumbrances. Other than the Company
Subsidiaries, neither the Company nor any Company Subsidiary owns any equity
interest in any person.

     3.5  No Violation. Neither the execution and delivery by the Company of
this Agreement, nor the consummation by the Company of the transactions
contemplated hereby and thereby in accordance with the terms of such agreements
will: (i) conflict with or result in a breach of any provisions of the
Certificate of Incorporation or the Bylaws of the Company; (ii) result in a
breach or violation of, or a default under, any existing Company Employee Plans,
or any grant or award made under any of the foregoing; or (iii) violate,
conflict with, result in a breach of any provision of, constitute a default (or
an event which, with notice or lapse of time or both, would constitute a
default) under, result in the termination or in a right of termination or
cancellation of, accelerate the performance required by, result in the
triggering of any payment or other material obligations pursuant to, result in
the creation of any lien, security interest, charge or encumbrance upon any of
the material properties of the Company or any of the Company Subsidiaries under,

Company or any of the Company Subsidiaries is a party, or by which the Company
or any of the Company Subsidiaries or any of their respective properties is
bound or to the knowledge of the Company affected, except for any of the
foregoing matters which would not (a) result in a Company Material Adverse
Effect, or (b) impair in any material respect the ability of the Company to
perform its obligations under this Agreement, or (c) prevent or materially delay
the consummation of any of the transactions contemplated by this Agreement; or
(iv) other than (a) filings by the Company required under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976 (the "HSR Act"), (b) the filing with the
Securities and Exchange Commission (the "SEC") of a proxy statement relating to
the approval by the Company's stockholders of this Agreement and such reports

this Agreement, (c) the filing of the Certificate of Merger with the Delaware
Secretary of State and (d) the filings and notifications required by the rules
of the Nasdaq National Market, required by or with respect to the Company or any

<PAGE>   7

Company of the Merger, any consent, approval or authorization of, or
declaration, filing or registration with, any domestic governmental or
regulatory authority, other than consents, approvals, authorizations,
declarations or filings or registration which, if not obtained or made, would
not (a) result in a Company Material Adverse Effect, (b) impair in any material
respect the ability of the Company to perform its obligations under this
Agreement, or (c) prevent or materially delay the consummation of any of the
transactions contemplated by this Agreement.

     3.6  SEC Documents; Undisclosed Matters.

          (a) The Company has filed all required forms, reports, schedules,
     statements and other documents (including exhibits and other information
     incorporated therein) with the SEC since January 1, 1997 (collectively, the
     "Company Reports"). As of the respective dates they were filed, or, if
     amended, as of the date of the filing of the last such amendment, each
     Company Report, (i) complied as to form in all material respects with the
     applicable requirements of the Securities Act, the Exchange Act, and the
     rules and regulations thereunder applicable to such Company Reports and
     (ii) at the time they were filed did not contain any untrue statement of a
     material fact or omit to state a material fact required to be stated
     therein or necessary to make the statements made therein, in the light of
     the circumstances under which they were made, not misleading. Each of the
     consolidated balance sheets included in or incorporated by reference into
     the Company Reports (including the related notes and schedules) fairly
     presents in all material respects the consolidated financial position of
     the Company and each of the Company Subsidiaries as of its date, and each
     of the consolidated statements of operations, stockholders' equity and cash
     flows included in or incorporated by reference into the Company Reports
     (including any related notes and schedules) fairly presents in all material
     respects the financial position, results of operations and cash flows, as
     the case may be, of the Company and each of the Company Subsidiaries for
     the periods set forth therein (subject, in the case of unaudited
     statements, to normal year-end audit adjustments which would not be
     material in amount or effect, and the absence of footnotes), in each case
     (x) in accordance with GAAP consistently applied during the periods
     involved, except as may be noted therein and (y) in compliance as to form
     in all material respects with the published rules and regulations of the
     SEC with respect thereto as of the date they were filed or, if amended, as
     of the date of the filing of the last such amendment.

          (b) Except (i) as set forth in the Company Reports (including the
     financial statements and notes thereto contained therein), (ii) for
     liabilities set forth in this Agreement, (iii) for liabilities described in
     Section 3.6 of the Company Disclosure Schedule or incurred in the ordinary
     course of business consistent with past practice, neither the Company nor
     any of the Company Subsidiaries has any liabilities or obligations of any
     nature (whether accrued, absolute or contingent or otherwise) which,
     individually or in the aggregate, would have a Company Material Adverse
     Effect.

     3.7  Litigation. Except as disclosed in the Company Reports, there are no
actions, suits or proceedings pending against the Company or any of the Company
Subsidiaries or, to the knowledge of the Company, threatened against the Company
or any of the Company Subsidiaries that, individually or in the aggregate, would
have a Company Material Adverse Effect, nor is there any judgment, decree,
injunction, rule, order, action, demand, or requirement of any governmental
entity or other regulatory body or arbitrator outstanding against, or, to the
knowledge of the Company, any investigation by any governmental entity or other
regulatory body involving the Company or any of the Company Subsidiaries that
individually or in the aggregate would have a Company Material Adverse Effect.

     3.8  Compliance with Laws.

          (a) Each of the Company and the Company Subsidiaries is in compliance
     with all statutes, laws, ordinances, rules, regulations, judgments, orders
     and decrees of any governmental entity or regulatory entity (other than

     business or operations, except for instances of noncompliance that
     individually or in the aggregate would not have a Company Material Adverse
     Effect. Each of the Company and the Company Subsidiaries has in effect all
     approvals, authorizations, certificates, filings, franchises, licenses,

     operate its properties and assets and to carry on its business and
     operations as now conducted, except for the failure to have such Permits
     that individually or in the aggregate would not have a Company Material
     Adverse Effect. There has occurred no default under, or violation of, any
     such Permit, except for defaults under, or violations of, Permits that
     individually or in the aggregate would not have a Company Material Adverse
     Effect. The Merger, in and of itself, would not cause the revocation or
     cancellation of any such Permit that individually or in the aggregate would
     have a Company Material Adverse Effect.

          (b) Except for those matters that individually or in the aggregate
     would not have a Company Material Adverse Effect: (A) each of the Company
     and the Company Subsidiaries is, and has been, in compliance with all
     applicable Environmental Laws; (B) during the period of ownership or
     operation by the Company or the Company Subsidiaries of any of its
     currently or previously owned, leased or operated properties, no Hazardous
     Material has been treated or disposed of, and there have been no Releases
     or threatened Releases of Hazardous Material at, in, on, under or affecting
     such properties or any contiguous site by the Company or the Company
     Subsidiaries, or, to the knowledge of the Company and the Company
     Subsidiaries, by any other person or entity; (C) prior to the period of
     ownership or operation by the Company or the Company Subsidiaries of any of
     its currently or previously owned, leased or operated properties, to the
     knowledge of the Company and the Company Subsidiaries, no Hazardous
     Material was treated, stored, or disposed of, and there were no Releases of
     Hazardous Material at, in, on, under or affecting any such property or any
     contiguous site; and (D) neither the Company nor the Company Subsidiaries
     have received any written notice of, or entered into or assumed by
     contract, judicial or administrative settlement, or operation of law any
     indemnification obligation, order, settlement or decree relating to: (1)
     any violation of any Environmental Laws or the institution or pendency of
     any suit, action, claim, proceeding or investigation by any governmental
     entity, regulatory entity or any third party in connection with any alleged
     violation of Environmental Laws or any Release of Hazardous Materials, (2)
     the response to or remediation of Hazardous Material at or arising from any
     of the Company's or its Subsidiaries' activities or properties or any other
     properties or (3) payment for any response action relating to or

     or the Company Subsidiaries' properties, activities, or any other
     properties.

     3.11  Employee Benefit Plans.

          (a) Schedule 3.11 of the Company Disclosure Schedule contains a list
     of each plan, program, arrangement and contract which is maintained or
     sponsored by the Company or any Company Subsidiaries or under which the
     Company or any of the Company Subsidiaries is obligated to make
     contributions or to which the Company or any Company Subsidiary otherwise
     have or may have any liability, contingent or otherwise, either directly or
     as a result of an ERISA Affiliate (as defined below), and which provides
     benefits or compensation to or on behalf of employees or former employees
     and their beneficiaries or directors, agents or independent contractors,
     including but not limited to executive arrangements, employment agreements,
     severance policies or agreements, sick leave, vacation pay, consulting or
     other compensation arrangements, bonus plan, stock option or stock purchase
     plans, and any other equity compensation plans or arrangements, any plans
     subject to section 125 of the Code, any plans providing benefits or
     payments in the event of a change of ownership or control, and "employee
     benefit plans" as defined in Section 3(3) of the Employee Retirement Income
     Security Act of 1974, as amended ("ERISA"). All such plans, programs,
     arrangements, practices or contracts are referred to herein as "Company
     Employee Plans." The Company has made available to Parent the plan
     documents or other writing constituting each Company Employee Plan that has
     been reduced to writing and, if applicable, the trust, insurance contract,
     service agreement, formal and informal amendments thereto, or other funding
     arrangement, the most recent ERISA summary plan description and any
     amendments or modifications thereof; all notices that were issued within
     the preceding three years by the IRS, Department of Labor, or any other
     governmental entity with respect to the Company Employee Plans; all minutes
     and resolutions describing the manner in which the Company Employee Plan is
     or has been administered or describing corrections to the administration of
     a Company Employee Plan; and the three (3) most recently filed Forms 5500
     and actuarial report for each such Company Employee Plan. The Company has
     made available to Parent accurate copies of the most recent favorable
     determination letters for all Company Employee Plans qualified under
     Section 401(a) of the Code. "ERISA Affiliate" means any person, together
     with the Company or any Company Subsidiary, is or was at any time treated
     as a

                                       10


<PAGE>   11

     single employer under Section 414 of the Code or Section 4001 of ERISA and
     any general partnership of which the Company or any Company Subsidiary is
     or has been a general partner.

          (b) The Company and any Company Subsidiary does not sponsor, maintain
     or contribute to, and has never sponsored, maintained or contributed to, or
     had any liability with respect to, any employee benefit plan subject to
     Section 302 of ERISA, Section 412 of the Code or Title IV of ERISA. No
     Company Employee Plan is a multiemployer plan (as defined in Section 3(37)
     of ERISA), and neither the Company nor any Company Subsidiary is, or has
     been, a participant in a multiemployer plan.

          (c) Neither the Company nor any of the Company Subsidiaries is
     obligated to provide post-employment or retirement medical benefits or any
     other unfunded welfare benefits to or on behalf of any Person who is no
     longer an employee of Company or any of the Company Subsidiaries, except
     for health continuation coverage as required by Section 4980B of the Code
     or Part 6 of Title I of ERISA.

          (d) The Company and any Company Subsidiary has no liability with
     respect to any benefit plan or arrangement other than the Company Employee
     Plans that would result in a Company Material Adverse Effect. Each Company
     Employee Plan has at all times been maintained, by its terms and in
     operation, in accordance with all applicable laws, and each of those
     Company Employee Plans which are intended to be qualified under Section
     401(a) of the Code has at all times been maintained, by its terms and in
     operation, in accordance with Section 401(a) of the Code, in each case
     except where a failure to be so maintained would not have a Company
     Material Adverse Effect; and all reporting, disclosure, and notice
     requirements of ERISA, the Code and other applicable laws have been
     satisfied in all material respects with respect to each Company Employee
     Plan.

          (e) No non-exempt prohibited transaction (within the meaning of
     Section 4975 of the Code or Section 406 of ERISA) has occurred with respect
     to any Company Employee Plan maintained by the Company or any of the
     Company Subsidiaries that would result, directly or indirectly, in the
     imposition of an excise tax or other liability under the Code or ERISA,
     except for such a tax or other liability that would not have a Company
     Material Adverse Effect.

     With respect to any Company Employee Plan, to the knowledge of the Company
there has occurred no breach of any fiduciary duty described in Section 404 of
ERISA that could, if successful, result in any fiduciary duty described in 404
of ERISA that could, if successful, result in any liability, direct or indirect,
for the Company or any Company Subsidiary or any stockholder, officer, director,
or employee of the Company or any Company Subsidiary. No Company Employee Plan
is presently under audit or examination (nor has noticed been received of a
potential audit or examination) by the IRS, the Department of Labor, or any
other governmental entity, and no matters are pending with respect to any
Company Employee Plan under any IRS program.

          (f) The Company and the Company Subsidiaries have paid all amounts
     that the Company and the Company Subsidiaries are required to pay as
     contributions to the Company Employee Plans as of the last day of the most
     recent fiscal year of each of the Company Employee Plans; all benefits
     accrued under any funded or unfunded Company Employee Plan will have been
     paid, accrued or otherwise adequately reserved with GAAP; and all monies
     withheld from employee paychecks with respect to the Company Employee Plans
     have been transferred to the appropriate Company Employee Plan in a timely
     manner as required by applicable law.

          (g) To the knowledge of the Company, all persons classified by the
     Company and the Company Subsidiaries as independent contractors satisfy and
     have at all times satisfied the requirements of applicable law to be so
     classified; to the knowledge of the Company, the Company and the Company
     Subsidiaries have fully and accurately reported their compensation on IRS
     Forms 1099 when required to do so; and to the knowledge of the Company, the
     Company and the Company Subsidiaries have no obligations to provide
     benefits with respect to such persons under the Company Employee Plans or
     otherwise. No individuals are currently providing, or have ever provided,
     services to the Company or the Company Subsidiaries pursuant to a leasing
     agreement or similar type of arrangement, nor has the

                                       11


<PAGE>   12

     Company or the Company Subsidiaries entered into any arrangement whereby
     services will be provide by such individuals.

          (h) All Company Employee Plans may be amended or terminated without
     penalty by the Company at any time on or after the Closing Date.

          (i) All Company Employee Plans outside of the United States, if any,
     (the "Foreign Plans") are in material compliance with all applicable laws
     and have been operated in all material respects in accordance with the
     Foreign Plans' respective terms. There are no unfunded liabilities under,
     or in respect of, the Foreign Plans, and all contributions or other
     payments required to be made to, or in respect of, the Foreign Plans prior
     to the Effective Time have been made, or will be made, prior to the
     Effective Time.

     3.12  Intellectual Property. Each of the Company and the Company
Subsidiaries owns, or is validly licensed or otherwise has the right to use all
patents, patent applications, trademarks, trademark rights, trade names, trade
name rights, service marks, service mark rights, copyrights and other
proprietary intellectual property rights and computer programs (collectively,
"Intellectual Property Rights") which if the Company or the Company Subsidiaries
did not own or validly license or otherwise have the right to use would have a
Company Material Adverse Effect. Section 3.12 of the Company Disclosure Schedule
sets forth, as of the date hereof, a list of all material granted patents,
pending patent applications, registered trademarks and applications therefor
owned by or licensed to the Company or any of the Company Subsidiaries. No
claims are pending or, to the knowledge of the Company, threatened that the
Company or any of the Company Subsidiaries is infringing the rights of any
person with regard to any Intellectual Property Right which have or would have a
Company Material Adverse Effect. To the knowledge of the Company, no person is
infringing the rights of the Company or any of the Company Subsidiaries with
respect to any Intellectual Property Right which would have a Company Material
Adverse Effect. As of the date hereof, the Company has no knowledge that the
business of the Company and the Company Subsidiaries as presently conducted or
as presently contemplated does or will infringe (i) any granted patent or
existing trademark or (ii) any patent to be granted from a pending patent
application. No claims are pending or, to the knowledge of the Company, are
threatened challenging the validity of, ownership of or license to the
Intellectual Property Rights owned by or licensed to the Company and the Company
Subsidiaries which would have a Company Material Adverse Effect.

     3.13  Parent Stock Ownership. Neither the Company nor any of the Company
Subsidiaries beneficially owns any shares of Parent Common Stock or other
securities convertible into or exercisable for Parent Common Stock.

     3.14  Pooling of Interests; Tax Reorganization. To the knowledge of the
Company, there has been no action or omission by the Company or any of the
Company Subsidiaries which would prevent the accounting for the Merger as a
pooling of interests in accordance with Accounting Principles Board Opinion No.
16 ("APB No. 16"), the interpretative releases issued pursuant thereto, and the
pronouncements of the SEC. Neither the Company nor any of the Company
Subsidiaries has taken or agreed to take any action or knows of any fact or
circumstance that is reasonably likely to prevent the Merger from qualifying as
a reorganization within the meaning of Section 368(a) of the Code.

     3.15  State Takeover Statutes. The Company Board has approved this
Agreement and the Merger, and such approval is sufficient to render
inapplicable, to this Agreement and the Merger, the provisions of Section 203 of
the DGCL to the extent, if any, such Section is applicable to this Agreement and
the Merger. To the Company's knowledge, no other state antitakeover statute or
similar statute or regulation is applicable to the Merger or the other
transactions contemplated hereby.

     3.16  No Brokers. The Company has not entered into any contract,
arrangement or understanding with any person or firm which may result in the
obligation of the Company or Parent to pay any finder's fees, brokerage or
agent's commissions or other like payments in connection with the negotiations
leading to this Agreement or the consummation of the transactions contemplated
hereby, except that the Company has retained U.S. Bancorp-Piper Jaffray ("Piper
Jaffray") as its financial advisors.

has received the opinion of Piper Jaffray to the effect that, as of the date
hereof, the Exchange Ratio is fair to the holders of Company Common Stock from a
financial point of view.

     3.18  Insurance. Schedule 3.18 accurately sets forth as of the day
preceding the date hereof all policies of insurance, other than title insurance
policies, held by or on behalf of the Company and all outstanding claims
thereunder in excess, individually or in the aggregate, of $25,000. All such
policies of insurance are in full force and effect, and no notice of
cancellation has been received. In the reasonable judgment of the Company, such
policies are in amounts which are adequate in relation to the business and
properties of the Company, and all premiums to date have been paid in full.

     3.19  Contracts. As of the date of this Agreement, neither the Company nor
any Company Subsidiary is a party to, and none of their respective properties or
assets are bound by, any material contracts, including contracts relating to
distribution, sale, licensing, co-promotion marketing, manufacturing, third
party suppliers of active ingredients, bulk product and finished product to the
Company, other than contracts filed as exhibits to the Company Reports or listed
on Schedule 3.19. The Company has not received any notice from any other party
to any such material contract, and otherwise has no knowledge that such third
party intends to terminate, or not renew, any such material contract and no
right to terminate such material contract arises in connection with the
transactions contemplated hereby. As of the date hereof, the Company has made
available to Parent true and correct copies of all such material contracts.
Neither the Company nor any of the Company Subsidiaries, and, to the knowledge
of the Company, no other party thereto, is in violation of or in default under
(nor does there exist any condition which upon the passage of time or the giving
of notice or both would cause such a violation of or default under) any loan or
credit agreement, bond, note, mortgage, indenture, lease or other contract,
agreement, obligation, commitment, arrangement, understanding, instrument,
permit or license which is listed in Section 3.19 of the Company Disclosure
Schedule, except for violations or defaults that individually or in the
aggregate would not have a Company Material Adverse Effect. Neither the Company
nor any of the Company Subsidiaries is a party to or otherwise bound by any
agreement or covenant not to compete or by any agreement or covenant (other than
licenses or similar agreements permitting the Company to use the intellectual
property of a third party) restricting in any material respect the development,
marketing or distribution of the Company's or any of the Company Subsidiaries'
products or services or the conduct of their businesses.

     3.20  No Excess Parachute Payments; No Section 162(m) Payments. There will
be no payments or benefits to any "disqualified individual" (within the meaning
of Section 280G of the Code) that would constitute or result in an "excess
parachute payment" under Section 280G of the Code as a direct or indirect
consequence of the transactions contemplated by this Agreement, including,
without limitation, as a result of the acceleration of vesting or exercisability
of any options to purchase Company Common Stock held by "disqualified
individuals" as a direct or indirect consequence of the transactions
contemplated by this Agreement. No such Person is entitled to receive any
additional payment from the Company, the Surviving Corporation or any other
Person (a "Parachute Gross Up Payment") to reimburse such Person for the excise
tax imposed on such Person pursuant to Section 4999(a) of the Code. The Company
Employee Plans and other Company employee compensation arrangements in effect as
of the date of this Agreement have been designed so that the disallowance of a
deduction under Section 162(m) of the Code for employee remuneration will not
apply to any material amounts paid or payable by the Company or any of the
Company Subsidiaries under any such plan or arrangement and, to the knowledge of
the Company, no fact or circumstance exists that is reasonably likely to cause
such disallowance to apply to any such amounts.

     3.21  Title to Properties.

          (a) Each of the Company and the Company Subsidiaries has good and
     marketable title to, or valid leasehold interests in, all its material
     properties and assets used in the conduct of its business except for such
     as are no longer used or useful in the conduct of its businesses or as have
     been disposed of in the ordinary course of business and except for defects
     in title, easements, restrictive covenants and similar encumbrances that
     individually or in the aggregate would not materially interfere with its
     ability to conduct its business as currently conducted. All such material
     assets and properties, other than assets and

                                       13


<PAGE>   14

     properties in which the Company or any of the Company Subsidiaries has a
     leasehold interest, are free and clear of all liens, claims and
     encumbrances, except for liens, claims and encumbrances that individually
     or in the aggregate would not materially interfere with the ability of the
     Company and the Company Subsidiaries to conduct their respective businesses
     as currently conducted.

          (b) Each of the Company and the Company Subsidiaries has complied in
     all material respects with the terms of all material leases to which it is
     a party and under which it is in occupancy, and all such leases are in full
     force and effect, except for such noncompliance or failure to be in full
     force and effect that individually or in the aggregate would not have a
     Company Material Adverse Effect. Each of the Company and the Company
     Subsidiaries enjoys peaceful and undisturbed possession under all such
     material leases, except for failures to do so that individually or in the
     aggregate would not have a Company Material Adverse Effect.

     3.22  Supply and Distribution Relationships. Except as would not result in
a Company Material Adverse Effect, (i) the Company and the Company Subsidiaries
have in place supply and distribution agreements or arrangements sufficient to
meet the needs of the business of the Company as it is currently being conducted
and (ii) to the knowledge of the Company, no adverse change in those agreements
or arrangements is reasonably anticipated.

     3.23  Regulatory Compliance.

          (a) As to each product subject to the jurisdiction of the U.S. Food
     and Drug Administration ("FDA") under the Federal Food, Drug and Cosmetic
     Act and the regulations thereunder ("FDCA") (each such product, a
     "Pharmaceutical Product") that is manufactured, tested, distributed and/or
     marketed by the Company or any of its subsidiaries, such Pharmaceutical
     Product is being manufactured, tested, distributed and/or marketed in
     substantial compliance with all applicable requirements under FDCA and
     similar Legal Provisions, including those relating to investigational use,
     premarket approval, good manufacturing practices, labeling, advertising,
     record keeping, filing of reports and security, except where the failure to
     be in compliance would not have a Company Material Adverse Effect. Neither
     the Company nor the Company Subsidiaries has received any notice or other
     communication from the FDA or any other governmental entity, domestic or
     foreign (A) contesting the premarket approval of, the uses of or the
     labeling and promotion of any of the Company's or the Company Subsidiaries'
     products or (B) otherwise alleging any violation of any Legal Provision by
     the Company or the Company Subsidiaries which, in either case, would have a
     Company Material Adverse Effect.

          (b) No Pharmaceutical Products have been recalled, withdrawn,
     suspended or discontinued by the Company or any of its Subsidiaries in the
     United States or outside the United States (whether voluntarily or
     otherwise) since January 1, 1998. No proceedings in the United States and
     outside of the United States (whether completed or pending) seeking the
     recall, withdrawal, suspension or seizure of any Pharmaceutical Product are
     pending, or to the knowledge of the Company, threatened, against the
     Company or any of the Company Subsidiaries, nor have any such proceedings
     been pending at any time since January 1, 1998 which would have a Company
     Material Adverse Effect.

          (c) As to each biological or drug of the Company or its Subsidiaries
     for which a biological license application, new drug application,
     investigational new drug application or similar state or foreign regulatory
     application has been approved, the Company and the Company Subsidiaries are
     in substantial compliance with 21 U.S.C. sec. 355 or 21 C.F.R. Parts 312 or
     314 et seq., respectively, and similar Legal Provisions and all terms and
     conditions of such applications, except where the failure to be in
     compliance would not have a Company Material Adverse Effect. As to each
     such drug, the Company and any relevant Company Subsidiary, and the
     officers, employees or agents of the Company or such Company Subsidiary
     have included in the application for such drug, where required, the
     certification described in 21 U.S.C. sec. 335a(k)(1) or any similar Legal
     Provision and the list described in 21 U.S.C. sec. 335a(k)(2) or any
     similar Legal Provision, and such certification and such list was in each
     case true and accurate when made and remained true and accurate thereafter,
     except in the case where the failure of such application to be true and
     accurate would not have a Company Material Adverse Effect. In

                                       14


<PAGE>   15

     addition, the Company and the Company Subsidiaries are in substantial
     compliance with all applicable registration and listing requirements set
     forth in 21 U.S.C. sec. 360 and 21 C.F.R. Part 207 and all similar Legal
     Provisions.

          (d) Each article of any drug manufactured and/or distributed by the
     Company or any of the Company Subsidiaries is not adulterated within the
     meaning of 21 U.S.C. sec. 351 (or similar Legal Provisions) or misbranded
     within the meaning of 21 U.S.C. sec. 352 (or similar Legal Provisions), and
     is not a product that is in violation of 21 U.S.C. sec. 355 (or similar
     Legal Provisions), except where such failure in compliance with the
     foregoing would not have a Company Material Adverse Effect.

          (e) Neither the Company, nor any Company Subsidiary, nor any officer,
     employee or agent of either the Company or any Company Subsidiary has made
     an untrue statement of a material fact or fraudulent statement to the FDA
     or other governmental entity or regulatory entity, failed to disclose a
     material fact required to be disclosed to the FDA or any other governmental
     entity or regulatory entity, or committed an act, made a statement, or
     failed to make a statement that, at the time such disclosure was made,
     could reasonably be expected to provide a basis for the FDA or any other
     governmental entity or regulatory entity to invoke its policy respecting
     "Fraud, Untrue Statements of Material Facts, Bribery, and Illegal
     Gratuities", set forth in 56 Fed. Reg. 46191 (September 10, 1991) or any
     similar policy. Neither the Company nor any Company Subsidiary, nor any
     officer, employee or agent of either the Company or any Company Subsidiary,
     has been convicted of any crime or engaged in any conduct for which
     debarment is mandated by 21 U.S.C. sec. 335a(a) or any similar Legal
     Provision or authorized by 21 U.S.C. sec. 335a(b) or any similar Legal
     Provision.

          (f) Except as disclosed in the Company Reports, neither the Company
     nor any Company Subsidiary has received any written notice that the FDA or
     any other governmental entity or regulatory entity has commenced, or
     threatened to initiate, any action to withdraw its approval or request the
     recall of any product of the Company or any Company Subsidiary, or
     commenced, or overtly threatened to initiate, any action to enjoin
     production at any facility of the Company or any Company Subsidiary which
     would reasonably be expected to have a Company Material Adverse Effect.

     3.24  Commercial, Clinical and Investigational Drugs. As of the date of
this Agreement, to the knowledge of the Company, there are no facts or
circumstances that would materially and adversely affect the continued
marketing, manufacture, and sale of Actiq as currently conducted. As of the date
of this Agreement, to the knowledge of the Company, all material information
regarding the development and commercialization of products and services of the
Company have previously been disclosed to Parent.

     3.25  Agreement with Officers and Directors. Schedule 3.25 sets forth each
plan or agreement pursuant to which amounts may become payable (whether
currently or in the future) to current or former officers and directors of the
Company or any of the Company Subsidiaries as a result of or in connection with
the Merger.

                                   ARTICLE 4

            REPRESENTATIONS AND WARRANTIES OF PARENT AND MERGER SUB

     Except as set forth in the disclosure schedule delivered prior to the
execution hereof to the Company (the "Parent Disclosure Schedule"), Parent and
Merger Sub represent and warrant to the Company as of the date of this Agreement
as follows:

     4.1  Existence; Good Standing; Corporate Authority; Compliance with
Law. Each of Parent and Merger Sub is a corporation duly incorporated, validly
existing and in good standing under the laws of its jurisdiction of
incorporation. Parent is duly licensed or qualified to do business as a foreign
corporation and is in good standing under the laws of any other jurisdiction in
which the character of the properties owned or leased by it or in which the
transaction of its business makes such qualification necessary, except where the
failure to be so qualified or to be in good standing would not result in a
Parent Material Adverse Effect (as defined in Section 8.14 hereof). Parent has
all requisite corporate power and authority to own, operate and

                                       15


<PAGE>   16

lease its properties and carry on its business as now conducted or as described
in the Parent Reports as reasonably contemplated in the future. Parent has no
Subsidiaries other than those Subsidiaries set forth in Section 4.1 of the
Parent Disclosure Schedule (the "Parent Subsidiaries"). Each of the Parent
Subsidiaries is a corporation duly organized, validly existing and in good
standing, under the laws of the respective jurisdictions in which they are
incorporated.

     4.2  Authorization, Validity and Effect of Agreements. Each of Parent and
Merger Sub, respectively, has the requisite corporate power and authority to
execute and deliver this Agreement and all other agreements and documents
contemplated hereby and thereby, and perform its obligations hereunder and
thereunder. The consummation by Parent and Merger Sub, as applicable, of the
transactions contemplated hereby have been (i) unanimously approved by the Board
of Directors of Parent and Merger Sub, as applicable, (ii) approved by the
Parent as the sole stockholder of Merger Sub, and duly authorized by all
requisite corporate action. This Agreement constitutes the valid and legally
binding obligation of Parent and Merger Sub, enforceable in accordance with its
terms, subject to applicable bankruptcy, insolvency, moratorium or other similar
laws relating to creditors' rights and general principles of equity.

     4.3  Capitalization. The authorized capital stock of Parent consists of
100,000,000 shares of Parent Common Stock and 5,000,000 shares of Preferred
Stock ("Parent Preferred Stock"). As of July 12, 2000, there were 34,820,937
shares of Parent Common Stock and 2,500,000 shares of the $3.625 Convertible
Exchangeable Preferred Stock (the "Convertible Exchangeable Preferred Stock")
series of Parent Preferred Stock issued and outstanding. Since such date, no
additional shares of capital stock of Parent have been issued, except shares
issued pursuant to the exercise of options outstanding under Parent's stock
option plans (the "Parent Stock Option Plans"). Parent is a party to an Amended
and Restated Rights Agreement, dated as of January 1, 1999 (the "Parent Rights
Agreement"), with StockTrans, Inc. as Rights Agent. As of July 1, 2000, options
to acquire 3,768,298 shares of Parent Common Stock were outstanding pursuant to
the terms of the Parent Stock Option Plans and 1,000,000 shares of Series A
Junior Participating Preferred Stock were reserved for issuance in connection
with the rights issued pursuant to the Parent Rights Agreement. Since such date,
no additional options have been granted. Other than the Convertible Exchangeable
Preferred Stock, Parent has no outstanding bonds, debentures, notes or other
obligations the holders of which have the right to vote (or which are
convertible into or exercisable for securities having the right to vote) with
the stockholders of Parent on any matter. All such issued and outstanding shares
of Parent Common Stock are, and all shares of Parent Common Stock to be issued
pursuant to Section 2.2(a) hereof, when issued in accordance with the terms
hereof will be, duly authorized, validly issued, fully paid, nonassessable and
free of preemptive rights. Other than as set forth above, there are not, as of
July 12, 2000, any existing options, warrants, calls, subscriptions, convertible
securities, or other rights, agreements or commitments which obligate Parent or
any of the Parent Subsidiaries to issue, transfer or sell any shares of capital
stock of Parent or any of the Parent Subsidiaries.

     All of the issued and outstanding shares of capital stock of Merger Sub are
owned by Parent. Merger Sub has not engaged in any activities other than in
connection with its formation and the transactions contemplated by this
Agreement.

     4.4  Subsidiaries. Parent owns directly or indirectly each of the
outstanding shares of each of the Parent Subsidiaries. Each of the outstanding
shares of capital stock of each of the Parent Subsidiaries is duly authorized,
validly issued, fully paid and nonassessable, and is owned, directly or
indirectly, by Parent free and clear of all liens, pledges, security interests,
claims or other encumbrances.

     4.5  No Violation. Neither the execution and delivery by Parent and Merger
Sub of this Agreement nor the consummation by Parent and Merger Sub of the
transactions contemplated hereby in accordance with the terms hereof, will: (i)
conflict with or result in a breach of any provisions of the respective
Certificate of Incorporation or Bylaws of Parent or Merger Sub; (ii) result in a
breach or violation of, a default under, or the triggering of any payment or
other material obligations pursuant to, or accelerate vesting under, any of the
Parent Stock Option Plans, or any grant or award under any of the foregoing, or
violate, conflict with, result in a breach of any provision of, constitute a
default (or an event which, with notice or lapse of time or both, would
constitute a default) under, result in the termination or in a right of
termination or cancellation of,

                                       16


<PAGE>   17

accelerate the performance required by, result in the triggering of any payment
or other material obligations pursuant to, result in the creation of any lien,
security interest, charge or encumbrance upon any of the material properties of
Parent, any of the Parent Subsidiaries or Merger Sub under, or result in being
declared void, voidable, or without further binding effect, any of the terms,
conditions or provisions of any note, bond, mortgage, indenture, deed of trust
or any material license, franchise, permit, lease, contract, agreement or other
instrument, binding commitment or obligation to which Parent, any of the Parent
Subsidiaries or Merger Sub is a party, or by which Parent, any of the Parent
Subsidiaries or Merger Sub or any of their respective properties is bound or to
the knowledge of the Parent affected, except for any of the foregoing matters
which would not (a) result in a Parent Material Adverse Effect, (b) impair in
any material respects the ability of Parent to perform its obligations under
this Agreement, or (c) prevent or materially delay the consummation of any of
the transactions contemplated by this Agreement; or (iii) other than (a) filings
by Parent required under the HSR Act, (b) the filing with the SEC of a
Registration Statement on Form S-4, (c) the filing of the Certificate of Merger
with the Delaware Secretary of State, and (d) the submission to the Nasdaq
National Market of a listing application, require, by or with respect to Parent,
any of the Parent Subsidiaries or Merger Sub in connection with the execution
and delivery of this Agreement by Parent and Merger Sub or the consummation by
Merger Sub of the Merger, any consent, approval or authorization of, or
declaration, filing or registration with, any domestic governmental or
regulatory authority, other than consents, approvals, authorizations,
declarations or filings or registrations which, if not obtained or made, are not
reasonably likely to result in a Parent Material Adverse Effect.

     4.6  SEC Documents; Undisclosed Matters.

          (a) Parent has filed all required forms, reports, schedules,
     statements and other documents (including exhibits and other information
     incorporated therein) with the SEC since January 1, 1997 (collectively, the
     "Parent Reports"). As of the respective dates they were filed, or, if
     amended, as of the date of the filing of the last such amendment, each
     Parent Report, (i) complied as to form in all material respects with the
     applicable requirements of the Securities Act, the Exchange Act, and the
     rules and regulations thereunder applicable to such Parent Reports and (ii)
     at the time they were filed did not contain any untrue statement of a
     material fact or omit to state a material fact required to be stated
     therein or necessary to make the statements made therein, in the light of
     the circumstances under which they were made, not misleading. Each of the
     consolidated balance sheets included in or incorporated by reference into
     the Parent Reports (including the related notes and schedules) fairly
     presents in all material respects the consolidated financial position of
     Parent and each of the Parent Subsidiaries as of its date, and each of the
     consolidated statements of operations, stockholders' equity and cash flows
     included in or incorporated by reference into the Parent Reports (including
     any related notes and schedules) fairly presents in all material respects
     the financial position, results of operations and cash flows, as the case
     may be, of Parent and each of the Parent Subsidiaries for the periods set
     forth therein (subject, in the case of unaudited statements, to normal
     year-end audit adjustments which would not be material in amount or effect,
     and the absence of footnotes), in each case (x) in accordance with GAAP
     consistently applied during the periods involved, except as may be noted
     therein and (y) in compliance as to form in all material respects with the
     published rules and regulations of the SEC with respect thereto as of the
     date they were filed or, if amended, as of the filing of the last such
     amendment.

          (b) Except (i) as set forth in the Parent Reports (including the
     financial statements and notes thereto contained herein), (ii) for
     liabilities set forth in this Agreement, (iii) for liabilities described in
     Section 4.6 of the Parent Disclosure or incurred in the ordinary course of
     business consistent with past practice, the Parent has no liabilities or
     obligations of any nature (whether accrued, absolute or contingent or
     otherwise) which, individually or in the aggregate, would have a Parent
     Material Adverse Effect.

     4.7  Litigation. Except as disclosed in the Parent Reports, there are no
actions, suits or proceedings pending against Parent, any of the Parent
Subsidiaries or Merger Sub or, to the knowledge of Parent, threatened against
Parent, any of the Parent Subsidiaries or Merger Sub, that, individually or in
the aggregate would have a Parent Material Adverse Effect, nor is there any
judgment, decree, injunction, rule, order,

                                       17


<PAGE>   18

action, demand or requirement of any governmental entity or other regulatory
body or arbitrator outstanding against, or, to the knowledge of Parent, any
investigation by any governmental entity or other regulatory body involving the
Parent that individually or in the aggregate would have a Parent Material
Adverse Effect.

     4.8  No Violation of Law. The business and operations of Parent and the
Parent Subsidiaries have been conducted in compliance with all applicable laws,
ordinances, regulations and orders of all governmental entities and other
regulatory bodies, except where such noncompliance, individually or in the
aggregate, would not have a Parent Material Adverse Effect.

     4.9  Absence of Certain Changes. Other than as set forth in the Parent
Reports (i) since December 31, 1999 Parent has conducted its business only in
the ordinary course of such business, (ii) from December 31, 1999 to the date of
this Agreement there has not been any Parent Material Adverse Effect; and (iii)
since December 31, 1999, there has not been any material change in its
accounting principles, practices or methods, except as required under GAAP or
applicable law.

     4.10  Company Stock Ownership. Neither Parent nor any of the Parent
Subsidiaries beneficially owns any shares of Company Common Stock or other
securities convertible into or exercisable for Company Common Stock.

     4.11  Pooling of Interests; Tax Reorganization. To the knowledge of Parent,
there has been no action or omission by Parent or any of the Parent Subsidiaries
which would prevent the accounting for the Merger as a pooling of interests in
accordance with APB No. 16, the interpretive releases issued pursuant thereto,
and the pronouncements of the SEC. Neither Parent nor any of the Parent
Subsidiaries has taken or agreed to take any action or knows of any fact or
circumstance that is reasonably likely to prevent the Merger from qualifying as
a reorganization within the meaning of Section 368(a) of the Code.

     4.12  No Brokers. Parent has not entered into any contract, arrangement or
understanding with any person or firm which may result in the obligation of the
Company or Parent to pay any finder's fee, brokerage or agent's commissions or
other like payments in connection with the negotiations leading to this
Agreement or the consummation of the transactions contemplated hereby, except
that Parent has retained Robertson Stephens as its financial advisor.

     4.13  Opinion of Financial Advisor. The Board of Directors of Parent has
received the opinion of Robertson Stephens to the effect that, as of the date
hereof, the Exchange Ratio in the Merger is fair from a financial point of view
to the Parent.

                                   ARTICLE 5

                                   COVENANTS

     5.1  No Solicitation.

          (a) Without the prior written consent of Parent, from and after the
     date hereof, the Company will not, and will not authorize or permit any of
     its Subsidiaries or any officers, directors, employees, financial advisors,
     agents and other representatives of any of the foregoing
     ("Representatives") to, directly or indirectly: (i) solicit, initiate or
     encourage (including by way of furnishing information, other than public
     information in the ordinary course of business in response to an
     unsolicited request) or take any other action to facilitate knowingly any
     inquiries or the making of any proposal which constitutes or may reasonably
     be expected to lead to an Acquisition Proposal (as hereinafter defined)
     from any person; (ii) engage in any discussion with any third party other
     than its Representatives or negotiations relating to any Acquisition
     Proposal; or (iii) enter into any agreement with respect to, agree to,
     approve or recommend any Acquisition Proposal; provided, however, that
     notwithstanding any other provision hereof, the Company may, (A) at any
     time prior to the time the Company's stockholders shall have voted to
     approve this Agreement engage in discussions or negotiations with a third
     party (and may furnish such third party information concerning the Company
     and its business, properties and assets to such party) who (without any
     solicitation, initiation, encouragement, discussion or negotiation,
     directly or indirectly, by or with the Company or the Representatives after
     the date hereof) makes an unsolicited

                                       18


<PAGE>   19

     bona fide written Acquisition Proposal if, and only to the extent that, (1)
     the third party has first made an Acquisition Proposal that is financially
     superior to the transactions contemplated by this Agreement and, in the
     case of a cash offer, has demonstrated that the funds necessary for the
     Acquisition Proposal are reasonably likely to be available (as determined
     in good faith in each case by the Company's Board of Directors after
     consultation with its financial advisors) (such an Acquisition Proposal, a
     "Superior Proposal"), and the Company's Board of Directors shall conclude
     in good faith, after considering applicable provisions of state law, and
     after consulting with independent legal counsel that such action is
     necessary for the Board of Directors to act in a manner consistent with its
     fiduciary duties under applicable law, and (2) prior to furnishing such
     information to or entering into discussions or negotiations with such
     person or entity, the Company receives from such person or entity an
     executed confidentiality agreement substantially in the same form as the
     Confidentiality Agreement, and (3) the Company shall have fully complied
     with this Section 5.1; (B) comply with Rule 14e-2 promulgated under the
     Exchange Act with regard to a tender or exchange offer; and/or (C) accept a
     Superior Proposal from a third party, provided the Company terminates this
     Agreement pursuant to Section 7.3(a) hereof. As used herein, "Acquisition
     Proposal" means a proposal or offer for a tender or exchange offer, merger,
     consolidation or other business combination involving the Company or any
     Subsidiary of the Company or any proposal to acquire in any manner a
     substantial equity interest in, or a substantial portion of the assets of,
     the Company or any Subsidiary thereof.

          (b) The Company shall immediately cease and terminate any existing
     solicitation, initiation, encouragement, activity, discussion or
     negotiation with any parties conducted heretofore by the Company or its
     Representatives with respect to a potential Acquisition Proposal and shall
     promptly request the return of all confidential or proprietary information
     of the Company furnished to any of such parties. The Company shall notify
     Parent orally and in writing of any such inquiries, offers or proposals
     (including, without limitation, the terms and conditions of any such
     proposal and the identity of the person making it), within 24 hours of the
     receipt thereof, shall keep Parent informed of the status and details of
     any such inquiry, offer or proposal, and shall give Parent prompt prior
     written notice of (i) any meeting of the Board of Directors of the Company
     to take any action with respect to an Acquisition Proposal or to
     withdrawing or modifying, in a manner adverse to Parent, its recommendation
     to the Company's stockholders in favor of approval of the Merger, and (ii)
     any agreement to be entered into with any person making such inquiry, offer
     or proposal.

          (c) Prior to accepting a Superior Proposal, the Company shall, and
     shall cause its financial and legal advisors to, negotiate in good faith
     with Parent, for a period of not less than five business days, to make such
     changes to the terms and conditions of this Agreement as would enable the

5.1(c) above. The Company Board shall recommend such approval and shall use its
reasonable best efforts to solicit such approval, including, without limitation,
timely mailing the Proxy Statement/Prospectus (as defined in Section 5.7).
Notwithstanding the foregoing or anything else contained in this Agreement,
prior to the adoption and approval of this Agreement and the approval of the
Merger by the holders of a majority of the shares of Company Stock, the Company
Board, to the extent it determines in good faith, after considering applicable
provisions of state law, and after consulting with independent legal counsel
that such action is necessary for the Board of Directors to act in a manner
consistent with its fiduciary duties under applicable law, may withdraw or
modify its approval or recommendation of this Agreement or the Merger; it being
agreed and understood that any such withdrawal or modification in a manner
materially adverse to the Parent shall give rise to the right of Parent to
terminate under Section 7.4(a) below.

     5.4  Reasonable Efforts; Further Assurances. Subject to the terms and
conditions herein provided, each of the parties hereto will promptly file and
prosecute diligently the applications and related documents required to be filed

contemplated hereby, including filings under the HSR Act requesting early
termination of the applicable waiting period. Each party hereto agrees to use
all commercially reasonable efforts to, and shall take, or cause to be taken,
all action and to do, or cause to be done, all things necessary, proper or
advisable under applicable laws and regulations, to consummate and make
effective the transactions contemplated by this Agreement as promptly as
practicable. In case at any time after the Effective Time any further action is
necessary or desirable to carry out the purposes of this Agreement, the proper
officers and directors of each corporation which is a party to this Agreement
shall take all such necessary action. Each of the parties hereto agrees to
defend vigorously against any actions, suits or proceedings in which such party
is named as defendant which seeks to enjoin, restrain or prohibit the
transactions contemplated hereby or seeks damages with respect to such
transactions.

     5.5  Inspection of Records. From the date hereof to the Effective Time, the
Company and Parent shall (i) allow all designated officers, attorneys,
accountants and other representatives of their respective companies reasonable
access at all reasonable times to the offices, records and files,
correspondence, audits and properties, as well as to all information relating to
commitments, contracts, titles and financial position, or otherwise pertaining
to the business and affairs, of the other party and their Subsidiaries, (ii)
furnish to such other party and such other party's counsel, financial advisors,
auditors and other authorized representatives such financial and operating data
and other information as such persons may reasonably request and (iii) instruct
employees, counsel and financial advisors to cooperate with such party in such
party's investigation of the business of the other party and its Subsidiaries.
Except as required by law, Parent and the Company will hold, and will cause
their respective officers, employees, accountants, counsel, financial advisors
and other representatives and affiliates to hold, any and all information
received from the Company or from Parent, as the case may be, directly or
indirectly, in confidence, in accordance with the Confidentiality Agreement
dated as of June 5, 2000 between Parent and the Company (as it may be amended
from time to time, the "Confidentiality Agreement").

     5.6  Publicity. The initial press release relating to this Agreement shall
be a joint press release in the form heretofore agreed to by the parties and
thereafter the Company and Parent shall, subject to their respective legal
obligations (including requirements of stock exchanges and other similar
regulatory bodies), consult with each other, and use reasonable efforts to agree
upon the text of any press release, before issuing any such press release or
otherwise making public statements with respect to the transactions contemplated
hereby and in making any filing with any federal or state governmental or
regulatory agency or with any national securities exchange with respect thereto.
The parties hereto agree and acknowledge that the Company may, after the signing
of this Agreement, file a copy of this Agreement with the SEC on Form 8-K.

     5.7  Registration Statement. Parent and the Company shall cooperate and
promptly prepare and Parent shall file with the SEC as soon as practicable a
Registration Statement on Form S-4 (the "Form S-4") under the Securities Act,
with respect to the Parent Common Stock issuable in the Merger, which
Registration Statement shall contain the proxy statement with respect to the
meeting of the stockholders of the Company in connection with the Merger (the
"Proxy Statement/Prospectus"). The respective parties will cause the Proxy
Statement/Prospectus and the Form S-4 to comply as to form in all material
respects with the applicable provisions of the Securities Act, the Exchange Act
and the rules and regulations thereunder. Parent shall use reasonable efforts,
and the Company will cooperate with Parent, to have the Form S-4 declared
effective by the SEC as promptly as practicable. Parent shall take all action
required to obtain, prior to the effective date of the Form S-4, all necessary
state securities law or "Blue Sky" permits or approvals required to carry out
the transactions contemplated by this Agreement. The information supplied by the
Company for inclusion or incorporation by reference in the Proxy
Statement/Prospectus and the Form S-4, shall not (i) at the time the Form S-4 is
declared effective, (ii) at the time the Proxy Statement/Prospectus (or any
amendment thereof or supplement thereto) is first mailed to holders of Company
Common Stock, and (iii) at the time of the Company Stockholders Meetings,
contain any untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein, in
the light of the circumstances under which they are made, not misleading. The
information supplied by Parent for inclusion or incorporation by reference in
the Proxy Statement/Prospectus and the Form S-4, shall not (i) at the time the
Form S-4 is declared effective, (ii) at the time the Proxy Statement/Prospectus
(or any

                                       22


<PAGE>   23

amendment thereof or supplement thereto) is first mailed to holders of Company
Common Stock, and (iii) at the time of the Company Stockholders Meetings,
contain any untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein, in
the light of the circumstances under which they are made, not misleading. No
amendment or supplement to the Proxy Statement/Prospectus will be made by the
Company without the approval of Parent and no amendment of the Form S-4 will be
made by Parent without the approval of the Company (such consent not to be
unreasonable withheld or delayed). Parent will advise the Company, promptly
after it receives notice thereof, of the time when the Form S-4 has become
effective or any supplement or amendment has been filed, the issuance of any
stop order, the suspension of the qualification of the Parent Common Stock
issuable in connection with the Merger for offering or sale in any jurisdiction,
or any request by the SEC for amendment of the Proxy Statement/Prospectus or the
Form S-4 or comments thereon and responses thereto or requests by the SEC for
additional information.

     5.8  Listing Application/De-Listings.

          (a) Parent shall promptly prepare and submit to the Nasdaq National
     Market a listing application covering the shares of Parent Common Stock
     issuable in the Merger and upon exercise of the Parent Options, and shall
     use all reasonable efforts to obtain, prior to the Effective Time, approval
     for the listing of such Parent Common Stock, subject to official notice of
     issuance.

          (b) The parties shall use their reasonable best efforts to cause the
     Surviving Corporation to cause the Company Common Stock to be de-listed
     from NASDAQ and de-registered under the Exchange Act as soon as practicable
     following the Effective Time.

     5.9  Affiliate Letters. No later than thirty (30) days prior to the date of
the Company Stockholders' Meeting, the Company shall deliver to Parent a letter
identifying all Persons who are, at the time this Agreement is submitted for
adoption by the stockholders of the Company, "affiliates" of the Company (other
than persons who have, on or prior to the date hereof, executed and delivered
affiliate letters to the Parent) for purposes of Rule 145 under the Securities
Act or for purposes of qualifying the Merger for pooling of interests accounting
treatment under Opinion 16 of the Accounting Principles Board and its related
interpretations. The Company shall take all actions reasonably necessary to
deliver or cause to be delivered to Parent, prior to the Closing Date, from each
such person an affiliate letter in the form of the affiliate letters delivered
to the Parent prior to the date hereof (an "Affiliate Letter").

     5.10  Expenses. Except as otherwise provided in Section 7.5 hereof, whether
or not the Merger is consummated, all costs and expenses incurred in connection
with this Agreement and the transactions contemplated hereby shall be paid by
the party incurring such expenses.

     5.11  Directors' and Officers' Indemnification and Insurance.

          (a) Parent agrees that all rights to indemnification and exculpation
     from liabilities for acts or omissions occurring at or prior to the
     Effective Time now existing in favor of the current or former directors or
     employees or officers of the Company as provided in the Certificate of
     Incorporation or Bylaws of the Company or any indemnification agreement
     between such directors or officers and the Company (in each case, as in
     effect on the date hereof) shall be assumed by the Surviving Corporation in
     the Merger, without further action, as of the Effective Time and shall
     survive the Merger and shall continue in full force and effect in
     accordance with their terms.

          (b) Parent shall cause to be maintained, for a period of not less than
     six years from the Effective Time, the Company's current directors' and
     officers' liability insurance policy to the extent that it provides
     coverage for events occurring prior to the Effective Time (the "D&O
     Insurance") for all present and former directors and officers of the
     Company or any Company Subsidiary, so long as the annual premium therefor
     would not be in excess 150% of the last annual premium paid for the D&O
     Insurance prior to the date of this Agreement, (such premium being the
     "Maximum Premium"); provided that Parent may, in lieu of maintaining such
     existing D&O Insurance as provided above, cause no less favorable coverage
     to be provided under any policy maintained for the benefit of the directors
     and

                                       23


<PAGE>   24

     officers of Parent or a separate policy provided by the same insurer. If
     the existing D&O Insurance expires, is terminated or canceled by the
     insurer or if the annual premium would exceed the Maximum Premium during
     such period, Parent shall obtain, in lieu of such D&O Insurance, such
     comparable directors' and officers' liability insurance as can be obtained
     for the remainder of such period for an annualized premium not in excess of
     the Maximum Premium and on terms and conditions no less advantageous than
     the existing D&O Insurance.

          (c) The provisions of this Section shall survive the Merger and are
     intended to be for the benefit of, and shall be enforceable by, each of the
     Indemnified Parties, their heirs and their representatives.

     5.12  Benefit Arrangements.

          (a) From and after the Effective Time, Parent shall (i) permit each
     Company employee and officer who renders services for Parent or any Parent
     Subsidiary (including the Company or any Company Subsidiary) after the
     Effective Time ("Company Employees") to participate in the employee benefit
     plans and arrangements covering Parent's employees and officers (including
     employee benefit plans as defined in Section 3(3) of ERISA, arrangements
     providing for insurance coverage or workers' compensation benefits,
     incentive or deferred bonus arrangements, severance arrangements, equity
     compensation and deferred compensation plans, and vacation programs,
     whether or not sponsored by Parent) ("Parent Benefit Plans") to the same
     extent as similarly situated employees of Parent, (ii) give each Company
     Employee credit for all service with the Company prior to the Effective
     Time, (including service with any Subsidiary or affiliate of the Company)
     for purposes of eligibility and vesting, but not benefit accrual, under all
     Parent Benefit Plans, (iii) not subject any Company employee to any waiting
     periods or limitations on benefits for pre-existing conditions under Parent
     Benefit Plans, except to the extent such Company Employee was subject to
     such limitation under Company's Employee Benefit Plans, and (iv) credit all
     Company Employees with one full year's deductible under the Company's
     healthcare plans for the plan year that includes the Effective Time.
     Notwithstanding the foregoing, Parent may continue, for the benefit of
     Company Employees, any of the Company Employee Plans as in effect prior to
     the Closing Date, in lieu of permitting such Company Employees to
     participate in any of the Parent Benefit Plans as provided in (i) above.

          (b) Prior to the Closing Date, the Company and the Company
     Subsidiaries shall take whatever action is necessary to cause the adoption
     of resolutions terminating the Company 401(k) Retirement Savings Plan as
     of, or prior to, the Closing Date, subject to subsequent governmental
     approval as the Company deems appropriate. Prior to the Closing Date, the
     Company and the Company Subsidiaries shall also take whatever action is
     necessary to terminate the Company Employee Stock Purchase Plan as of, or
     prior to, the Closing Date.

     5.13  Section 16 Matters. Parent and the Company shall take all actions
reasonably necessary to cause the transactions contemplated hereby and any other
dispositions of equity securities of the Company (including derivative
securities) or acquisitions of Parent equity securities (including derivative
securities) in connection with this Agreement by each individual who (a) is a
director or officer of the Company or (b) at the Effective Time, will become a
director or officer of Parent, to be exempt under Rule 16b-3 promulgated under
the Exchange Act.

     5.14  Tax-Free Reorganization. Each of Company, Parent and Merger Sub shall
take all necessary actions to obtain tax-free reorganization treatment under
Section 368(a) of the Code and shall not take any position or action that is
inconsistent with such treatment.

     competent jurisdiction which restrains, enjoins or otherwise prohibits the
     Merger shall be in effect. In the event any such order, decree, ruling or
     other action shall have been issued, each party agrees to use commercially
     reasonable efforts to have any such order, decree, ruling or other action
     reversed and any such restraint or injunction lifted.

     curable or, if curable, is not cured within thirty (30) days after written
     notice of such breach is given by Parent to the Company, or

          (c) there has been a material breach of any of the covenants or
     agreements set forth in this Agreement on the part of the Company, which
     breach would cause the condition set forth in Section 6.3(a)(i) to not be
     satisfied, which breach is not curable or, if curable, is not cured within
     thirty (30) days after written notice of such breach is given by Parent to
     the Company.

     7.5  Effect of Termination and Abandonment.

          (a) The Company shall pay Parent a fee of $15 million (the
     "Termination Fee"), which amount shall be payable prior to any termination
     by the Company in the case of clause (i) below (with any such payment being
     a condition precedent to any such termination), and Parent's reasonable
     documented out-of-pocket expenses, not to exceed $1,000,000 in the
     aggregate, in connection with this Agreement and the transactions
     contemplated hereby (the "Parent Expenses"), which amount shall be payable
     within two business days of receipt of an invoice therefor, if this
     Agreement (A) is terminated by Parent pursuant to Section 7.4(a) hereof, or
     by the Company pursuant to Section 7.3(a) hereof, or (B) is terminated as a
     result of the Company's breach of Section 5.1 hereof which is not cured
     within ten (10) days after notice thereof.

          (b) In the event of termination of this Agreement by Parent pursuant
     to Section 7.4(b) or (c), the Company shall pay to Parent the Parent
     Expenses, which amount shall be payable within two business days of receipt
     of an invoice therefor; provided however, that in the event that within
     twelve (12) months after termination of this Agreement the Company shall
     have entered into an agreement with respect to, or consummated, an
     Acquisition Proposal which shall have existed at any time during the period
     between the date hereof and the date of such termination, then, the Company
     shall pay Parent the Termination Fee in addition to the Parent Expenses.

          (c) The Company acknowledges that the agreements contained in Section
     7.5(a) and (b) are an integral part of the transactions contemplated in
     this Agreement, and that, without these agreements, Parent and Merger Sub
     would not enter into this Agreement; accordingly, if the Company fails to
     promptly pay the amount due pursuant to Section 7.5(a) or (b), and, in
     order to obtain such payment, Parent or Merger Sub commences a suit which
     results in a judgment against the Company, the Company shall pay to Parent
     its reasonable costs and expenses (including reasonable attorneys' fees) in
     connection with such suit, together with interest on the amount of the
     Termination Fee and the Parent Expenses at the prime rate of Chase
     Manhattan Bank N.A. in effect on the date such amounts were required to be
     paid. The payment of the Termination Fee and the Parent Expenses
     contemplated by Section 7.5(a), or the Parent Expenses and if applicable
     the Termination Fee contemplated by Section 7.5(b), as the case may be,
     shall terminate all obligations or liabilities of the Company under this
     Agreement, except as otherwise provided in Section 7.5(e) below.

          (d) In the event of termination of this Agreement by the Company
     pursuant to Section 7.3(b) or (c), the Parent shall pay to the Company the
     Company's reasonable documented out-of-pocket expenses, not to exceed
     $1,000,000 in the aggregate, in connection with this Agreement and the
     transactions contemplated hereby, which amount shall be payable within two
     (2) business days of receipt of an invoice therefor.

          (e) In the event of termination of this Agreement and the abandonment
     of the Merger pursuant to this Article 7, all obligations of the parties
     hereto shall terminate, except the obligations of the parties set forth in
     this Section 7.5 and Section 5.10 and except for the Confidentiality
     Agreement, provided that nothing in this Section 7.5(e) shall relieve any
     party from liability for willful breach, including, without limitation,
     attorneys' fees and the right to pursue any remedy at law or in equity.

     7.6  Extension; Waiver. At any time prior to the Effective Time, any party
hereto, by action taken by its Board of Directors, may, to the extent legally
allowed, (a) extend the time for the performance of any of the obligations or
other acts of the other parties hereto, (b) waive any inaccuracies in the
representations and warranties made to such party contained herein or in any
document delivered pursuant hereto and (c) 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.
