hereof and continuing until the earlier of (x) the consummation of the Offer or
(y) the termination of this Agreement in accordance with Section 10 hereof, each
of the Principal Stockholders hereby agree as follows:

                (a)     ATTENDANCE AT MEETINGS. At any annual or special meeting
        of the stockholders of the Company (including any adjournment thereof),
        however called, or in connection with any written consent of the
        stockholders of the Company, at which or in which matters relating to
        the Merger, the Merger Agreement or any transaction contemplated thereby
        are considered, the Principal Stockholder shall appear, or cause the
        holder of record on any applicable record date with respect to any Owned

                (b)     VOTING. At any meeting of the stockholders of the
        Company, however called, and in any action by consent of the
        stockholders of the Company, the Principal Stockholder shall vote, or

        Person also has the right to vote such Owned Shares) of the Principal
        Stockholder: (i) in favor of the Merger, the Merger Agreement (as
        amended from time to time) and the transactions contemplated by the
        Merger Agreement and (ii) against any Acquisition Proposal (as defined
        in the Merger Agreement) or any other action or agreement that is
        intended or which reasonably could be expected to (x) result in a breach
        of any covenant, representation or warranty or any other obligation or
        agreement of the Company under the Merger Agreement, (y) result in any
        of the conditions to the Company's obligations under the Merger
        Agreement not being fulfilled or (z) impede, interfere with, delay,
        postpone or materially adversely affect the Merger and the transactions
        contemplated by the Merger Agreement; provided, however that nothing in
        this Section 3(b) shall prevent such Principal Stockholder from voting
        in favor of any Acquisition Proposal if this Agreement has been
        terminated in accordance with Section 10 hereof.

        4.      ACKNOWLEDGMENT. The Principal Stockholders hereby acknowledge
the receipt and review of a copy of the Merger Agreement.

        5.      TERMINATION OF AGREEMENTS. Each of the Principal Stockholders
hereby agree that, prior to or at the Effective Time, it shall use its
commercially reasonable efforts to terminate or cause to be terminated all
agreements between the Company or any Subsidiary of the Company, on the one
hand, and the Principal Stockholder or any of its controlled Affiliates, on the
other hand, on terms and conditions mutually agreeable to Parent, the Company
and such Principal Stockholder. Notwithstanding the foregoing, nothing in this
Section 5 shall be construed to obligate the Principal Stockholder to cause to
be terminated any



                                       3
<PAGE>   4


agreement between such Principal Stockholder or one of its controlled
Affiliates, on the one hand, and the Company, on the other hand, (i) to the
extent that such agreement was entered into in the ordinary course of business
and (ii) to the extent that such agreement provides indemnification for the
benefit of such Principal Stockholder or its Affiliates.

        6.      REPRESENTATIONS AND WARRANTIES OF THE PRINCIPAL STOCKHOLDERS.
Each Principal Stockholder hereby represents and warrants to Parent and
Purchaser, as follows:

                (a)     EXISTENCE. If the Principal Stockholder is other than a
        natural Person, such Principal Stockholder has been duly organized and
        is validly existing and in good standing under the laws of the
        jurisdiction of its organization.

                (b)     POWER AND AUTHORITY. The Principal Stockholder has all
        necessary power and authority to enter into this Agreement, to perform
        its obligations hereunder and to consummate the transactions
        contemplated hereby, and the execution, delivery and performance of this
        Agreement by the Principal Stockholder and the consummation by the
        Principal Stockholder of the transactions contemplated hereby have been
        duly authorized by all necessary action on the part of the Principal
        Stockholder, and no other proceedings on the part of the Principal
        Stockholder are necessary to authorize the execution, delivery or
        performance of this Agreement or the consummation of the transactions
        contemplated hereby.

                (c)     EXECUTION. This Agreement has been duly and validly
        executed and delivered by the Principal Stockholder and, assuming the
        valid authorization, execution and delivery of this Agreement by the
        other parties hereto, constitutes a legal, valid and binding obligation
        of the Principal Stockholder, enforceable against the Principal
        Stockholder in accordance with its terms, except to the extent
        enforceability may be limited by bankruptcy, insolvency, moratorium or
        other similar laws affecting creditors' rights generally or by general
        principles governing the availability of equitable remedies.

                (d)     NO CONFLICT. None of the execution and delivery of this
        Agreement by the Principal Stockholder, the consummation by the
        Principal Stockholder of the transactions contemplated hereby or
        compliance by the Principal Stockholder with any of the provisions
        hereof shall (i) conflict with or violate the certificate of
        incorporation, or other organizational documents, of the Principal
        Stockholder, (ii) result in a violation or breach of, or constitute
        (with or without notice or lapse of time or both) a default (or give
        rise to any third party right of termination, cancellation, material
        modification or acceleration) under any of the terms, conditions or
        provisions of any note, loan agreement, bond, mortgage, indenture,
        license, contract, commitment, lease, permit, franchise, arrangement,
        understanding, agreement or other instrument or obligation of any kind
        to which the Principal Stockholder is a party or by which the Principal
        Stockholder or any of its properties or assets (including the Owned
        Shares) may be bound, or (iii) violate any order, writ, injunction,
        decree, judgment, law, statute, rule, regulation or administrative or
        arbitral order applicable to the Principal Stockholder or any of its
        properties or assets, excluding from the foregoing such violations,
        breaches or



                                       4
<PAGE>   5


        defaults which could not reasonably be expected to, individually or in
        the aggregate, have a material adverse effect on the Company or
        Principal Stockholder or which would not materially impair the ability
        of the Company or Principal Stockholder to consummate the transactions
        contemplated hereby.

                (e)     NO CONSENTS OR APPROVALS. The execution and delivery of
        this Agreement by the Principal Stockholder does not, and the
        performance of this Agreement by the Principal Stockholder shall not,
        require any consent, approval, authorization or permit of, or filing
        with or notification to, any court or arbitrator or any Governmental
        Entity, except for applicable requirements, if any, of the Exchange Act,
        and except where the failure to obtain such consents, approvals,
        authorizations or permits, or to make such filings or notifications,
        could not reasonably be expected to prevent or delay the performance by
        the Principal Stockholder of its obligations under this Agreement.

                (f)     TITLE TO THE OWNED SHARES. The Principal Stockholder is
        the Beneficial Owner or holder of record of the Owned Shares listed
        opposite its name on Schedule 1 hereto. Such Owned Shares are all the
        securities of the Company either Beneficially Owned or owned of record
        by the Principal Stockholder as of the date hereof and the Principal
        Stockholder owns no other rights or interests exercisable for or
        convertible into any securities of the Company. Such Owned Shares are
        owned free and clear of all security interests, liens, claims, pledges,
        options, rights of first refusal, agreements, limitations on the
        Principal Stockholder's voting rights, charges and other encumbrances of
        any nature whatsoever except, with respect to the Options, the option
        plans and agreements pursuant to which such options were issued. The
        Principal Stockholder has not appointed or granted any proxy, which
        appointment or grant is still effective, with respect to the Owned
        Shares.

                (g)     CONTINUOUS OWNERSHIP. Schedule 2 sets forth the
        respective dates of acquisition of the Owned Shares by the Principal
        Stockholder. The Principal Stockholder has Beneficially Owned the Owned
        Shares since the respective dates of acquisition of such Owned Shares as
        set forth on Schedule 2 and has not disposed of any Owned Shares since
        such respective acquisition dates.

        7.      COVENANTS.

                (a)     NO INCONSISTENT AGREEMENTS. The Principal Stockholders
        hereby covenant and agree that, except as contemplated by this
        Agreement, they shall not enter into any agreement, arrangement or
        understanding with, or grant a proxy or power of attorney to, any Person
        (other than Parent or Purchaser) with respect to the Owned Shares which
        would prevent the Company or the Principal Stockholders from complying
        with their obligations under this Agreement.

                (b)     RESTRICTION ON TRANSFER; PROXIES. The Principal
        Stockholders hereby covenant and agree that, until this Agreement is
        terminated in accordance with Section 10 hereof, the Company and
        Principal Stockholders shall not, directly or indirectly: (i) except for
        tendering such Owned Shares in the Offer as provided in



                                       5
<PAGE>   6


        Sections 2 hereof, Transfer (whether by operation of law, by agreement
        or otherwise) to any Person all or any portion of the Owned Shares and
        shall not cause any security interests, liens, claims, pledges, charges,
        encumbrances, options, rights of first refusals, agreements or other
        limitations on such Principal Stockholder's voting rights, to attach to
        the Owned Shares to be tendered to Purchaser pursuant to Section 2
        hereof or to the Options or any Owned Shares issuable thereunder; or
        (ii) grant any proxies or powers of attorney (other than to Parent or
        Purchaser), deposit any Owned Shares into a voting trust or enter into a
        voting agreement, understanding or arrangement with respect to such
        Owned Shares. Notwithstanding the foregoing, the Principal Stockholders
        may transfer any or all of their Owned Shares to one or more of their
        Affiliates; provided that, prior to effecting such Transfer, each such
        Affiliate shall agree in writing to be bound by the terms and conditions
        of this Agreement pursuant to an instrument, in form and substance
        reasonably satisfactory to Parent and Purchaser.

                (c)     NO SOLICITATION. From the date hereof until the
        consummation of the Offer or the termination of this Agreement in
        accordance with its terms, each Principal Stockholder (i) shall
        immediately terminate any discussions with any third party concerning an
        Acquisition Proposal and (ii) shall not, and shall not permit any of its
        Representatives to, directly or indirectly, (A) encourage, solicit,
        initiate or knowingly facilitate any inquiries or the making of any
        proposal or offer with respect to an Acquisition Proposal, (B)
        participate in any discussions or negotiations with, or provide any
        information to, or otherwise take any other action to assist or
        facilitate any Person or group (other than Parent or Purchaser or any
        Affiliate or associate of Parent or Purchaser) concerning any
        Acquisition Proposal, (C) enter into an agreement with any Person, other
        than Parent or Purchaser, providing for a possible Acquisition Proposal
        or (D) make or authorize any statement, recommendation or solicitation
        in support of any possible Acquisition Proposal by any Person, other
        than by Parent or Purchaser. Notwithstanding the foregoing, the
        Principal Stockholders or any of their Representatives may take any such
        actions in the Principal Stockholders' or any of their Representatives'
        capacity as a director or officer of the Company to the extent permitted
        pursuant to and in strict accordance with the terms of the Merger
        Agreement.

                (d)     NOTIFICATION. The Company and the Principal Stockholders
        hereby agree to notify Parent promptly of the number of any additional
        Shares and the number and type of any other shares of capital stock
        acquired by it, if any, after the date hereof.

        8.      STOP TRANSFER. The Principal Stockholders shall not request that
the Company or the Company's transfer agent register the transfer (book-entry or
otherwise) of any certificate or uncertificated interest representing any of the
Owned Shares, unless such transfer is made in compliance with this Agreement.
The Company agrees to take all action reasonably necessary, including the
delivery of stop-transfer or other similar instructions to its transfer agent,
to ensure compliance by the Principal Stockholders with the foregoing.

        9.      [INTENTIONALLY OMITTED].

        10.     TERMINATION. This Agreement, and all rights and obligations of
the parties hereunder, shall terminate upon the earlier of (a) the date upon
which the Parent shall have purchased and paid for all of the Owned Shares of
the Principal Stockholders in accordance with the Offer and (b) the date upon
which the Merger Agreement is terminated in accordance with its terms; provided,
however, that if the Merger Agreement is terminated by Parent pursuant to
Section 9.1(b)(i) (due to a failure of the condition set forth in paragraph e of
Annex A to the Merger Agreement) or Section 9.1(b)(v) of the Merger Agreement,
or by the Company under Section 9.1(b)(vi) of the Merger Agreement, the
Agreement shall not terminate unless and until the Termination Fee is paid by
the Company.

        11.     MISCELLANEOUS.

                (a)     [INTENTIONALLY OMITTED].

                (b)     ENTIRE AGREEMENT. This Agreement constitutes the entire
        agreement between the parties with respect to the subject matter hereof
        and supersedes all other prior agreements and understandings, both
        written and oral, between the parties with respect to the subject matter
        hereof.

                (c)     COSTS AND EXPENSES. All costs and expenses incurred in
        connection with this Agreement and the transactions contemplated hereby
        shall be paid by the party incurring such expenses.

                (d)     ASSIGNMENT. This Agreement and all of the provisions
        hereof shall be binding upon and inure to the benefit of the parties and
        their respective successors, personal or legal representatives,
        executors, administrators, heirs, distributees, devisees, legatees and
        permitted assigns, but neither this Agreement nor any of the rights,
        interests or obligations hereunder shall be assigned by either party
        (whether by operation of law or otherwise) without the prior written
        consent of the other party; PROVIDED, that Parent and Purchaser may
        assign their respective rights and obligations hereunder to any direct
        or indirect Subsidiary of Parent which is an assignee of such parties'
        rights and obligations under the Merger Agreement, but no such
        assignment shall relieve Parent or Purchaser, as the case may be, of its
        obligations hereunder. Nothing in this Agreement, express or implied, is
        intended to or shall confer upon any other Person any rights, benefits
        or remedies of any nature whatsoever under or by reason of this
        Agreement.

                (e)     AMENDMENTS; WAIVER. This Agreement may not be amended,
        changed, supplemented or otherwise modified or terminated, except upon
        the execution and delivery of a written agreement executed by each of
        the parties hereto. The parties may waive compliance by the other
        parties hereto with any representation, agreement or condition otherwise
        required to be complied with by such other party hereunder, but any such
        waiver shall be effective only if in writing executed by the waiving
        party.

                (f)     NOTICE. All notices and other communications hereunder
        shall be in writing and shall be deemed given upon (i) transmitter's
        confirmation of a receipt of a

If to a Principal Stockholder, to such address set forth on their respective
signature page to this Agreement:

or, in each case, to such other address or facsimile number as the Person to
whom notice is given shall have previously furnished to the others in writing in
the manner set forth above.

                (g)     SEVERABILITY. Any provision of this Agreement which is
        prohibited or unenforceable in any jurisdiction shall, as to such
        jurisdiction, be ineffective to the extent of such prohibition or
        unenforceability without affecting the validity or enforceability of the
        remaining provisions hereof. Any such prohibition or unenforceability in
        any jurisdiction shall not invalidate or render unenforceable such
        provision in any other jurisdiction. If any provision of this Agreement
        is so broad as to be unenforceable, the provision shall be interpreted
        to be only so broad as is enforceable.

                (h)     SPECIFIC PERFORMANCE. Each of the parties hereto
        acknowledges and agrees that in the event of any breach of this
        Agreement, each non-breaching party would be irreparably and immediately
        harmed and could not be made whole by monetary damages. It is
        accordingly agreed that the parties hereto (a) will waive, in any action
        for specific performance, the defense of adequacy of a remedy at law and
        (b) shall be entitled, in addition to any other remedy to which they may
        be entitled at law or in equity, to compel specific performance of this
        Agreement.

                (i)     REMEDIES. All rights, powers and remedies provided under
        this Agreement or otherwise available in respect hereof at law or in
        equity shall be cumulative and not alternative, and the exercise of any
        thereof by any party shall not preclude the simultaneous or later
        exercise of any other such right, power or remedy by such party. The
        failure of any party hereto to exercise any right, power or remedy
        provided under this Agreement or otherwise available in respect hereof
        at law or in equity, or to insist upon compliance by any other party
        hereto with its obligations hereunder, and any custom or practice of the
        parties at variance with the terms hereof, shall not constitute a waiver
        by such party of its right to exercise any such or other right, power or
        remedy or to demand such compliance.

                (j)     DIRECTORS' FIDUCIARY DUTIES. Notwithstanding anything
        herein to the contrary, nothing set forth herein shall in any way
        restrict any director, officer or employee in the exercise of his
        fiduciary or other duties as a director, officer or employee of the
        Company.

                (k)     GOVERNING LAW. This Agreement shall be governed and
        construed in accordance with the laws of the State of Delaware without
        giving effect to the principles of conflicts of law thereof.

                (l)     JURISDICTION. Each party to this agreement hereby
        irrevocably agrees that any legal action or proceeding arising out of or
        relating to this agreement or any agreements or transactions
        contemplated hereby shall be brought in the courts of the state of
        Delaware or the United states of America for the District of Delaware
        and hereby expressly submits to the personal jurisdiction and venue of
        such courts for the purposes



                                       9
<PAGE>   10


        thereof and expressly waives any claim of improper venue and any claim
        that such courts are an inconvenient forum.

                (m)     WAIVER OF JURY TRIAL. Parent, Purchaser, Company, and
        the Principal Stockholders hereby irrevocably waive, to the fullest
        extent permitted by law, all rights to trial by jury in any action,
        proceeding or counterclaim (whether based on contract, tort or
        otherwise) arising out of or relating to this agreement or any of the
        transactions contemplated hereby.

                (n)     HEADINGS; INTERPRETATION. The descriptive headings used
        herein are inserted for convenience of reference only and are not
        intended to be part of or to affect the meaning or interpretation of
        this Agreement. Whenever the context may require, any pronoun shall
        include the corresponding masculine, feminine and neuter forms.
        "Include," "includes," and "including" shall be deemed to be followed by
        "without limitation" whether or not they are in fact followed by such
        words or words of like import.

                (o)     COUNTERPARTS. This Agreement may be executed in
        counterparts, each of which shall be deemed to be an original, but all
        of which, taken together, shall constitute one and the same instrument.
