RECITALS

    A.        Each Stockholder “beneficially owns” (as such term is defined in
Rule 13d-3 promulgated under the Securities Exchange Act of 1934, as amended)
and is entitled to dispose of (or to direct the disposition of) and to vote (or
to direct the voting of) the number of shares of common stock, par value $0.001

stockholder’s name on Schedule A hereto (such shares of Company Common Stock,
together with all other shares of capital stock of the Company acquired and
beneficially owned by any Stockholder after the date hereof and during the term
of this Agreement, being collectively referred to herein as the “Subject
Shares”).

    B.        Concurrently with the execution and delivery of this Agreement,
Parent, Merger Sub and the Company have entered into the Merger Agreement
providing for the merger of Merger Sub with and into the Company, with the
Company continuing as the surviving corporation in the Merger (the “Merger”),
all upon the terms and subject to the conditions set forth therein.

    C.        The Stockholders desire to enter into this Agreement to induce
Parent and Merger Sub to enter into the Merger Agreement.

    D.        The Board of Directors of the Company has taken all actions
necessary and within its authority such that no restrictive provision of any
“fair price,” “moratorium,” “control share acquisition,” “business combination,”
“Stockholder protection,” “interested stockholder” or other similar
anti-takeover statute or regulation, including, without limitation, Section 203
of the General Corporation Law of the State of Delaware, or any restrictive
provision of the Certificate of Incorporation or By-Laws of the Company is, or
at the Effective Time will be, applicable to the Company, Parent, Merger Sub,
the Company Common Stock, the Merger or any other transaction contemplated by
this Agreement or the Merger Agreement.

        NOW, THEREFORE, in consideration of the foregoing and the mutual
premises, representations, warranties, covenants and agreements contained herein
and in the Merger Agreement, the parties hereto, intending to be legally bound,
hereby agree as follows:

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

        1.    Representations and Warranties of Each Stockholder.

        Each Stockholder, severally (and not jointly), hereby represents and

Stockholder in connection with this Agreement.

creditors’ rights generally, and (ii) general principles of equity (regardless
of whether considered in a proceeding at law or in equity).

understanding, agreement or other instrument or obligation to which Parent or
Merger Sub is a party or by which Parent or Merger Sub or any of their
respective assets may be bound, or (C) violate any order, writ, injunction,
decree, judgment, statute, rule or regulation applicable to Parent or Merger
Sub, except for any of the foregoing as would not prevent Parent or Merger Sub
from performing their respective obligations under this Agreement.

        3.        Covenants of Each Stockholder.

        Until the termination of this Agreement in accordance with Section 5,
each Stockholder, in his capacity as such, agrees as follows:

3

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

        (a)         At the Company Stockholders’ Meeting or at any adjournment,
postponement or continuation thereof or in any other circumstance occurring
prior to the Company Stockholders’ Meeting upon which a stockholder vote or
other stockholder approval with respect to the Merger and the Merger Agreement
is sought, each Stockholder shall vote (or cause to be voted) the Subject Shares
beneficially owned (as defined in Recital A above) by such Stockholder (i) in
favor of the approval of the Merger and the approval and adoption of the Merger
Agreement and the terms thereof, in favor of each of the other actions
contemplated by the Merger Agreement and in favor of any action in furtherance
of any of the foregoing; (ii) against any action or agreement that would result
in a breach of any representation, warranty, covenant or obligation of the
Company in the Merger Agreement and (iii) except with the written consent of
Parent and Merger Sub, against (A) any Company Acquisition Proposal, (B) any
reorganization, recapitalization, dissolution or liquidation of the Company or
any subsidiary of the Company; (C) any change in the individuals who serve as
members of the board of directors of the Company; (D) any amendment to the
Company’s certificate of incorporation or bylaws; (E) any material change in the
capitalization of the Company or the Company’s corporate structure; and (F) any
other action which is intended, or could reasonably be expected, to impede,
interfere with, delay, postpone, discourage or adversely affect the Merger or
any of the other transactions contemplated by the Merger Agreement or this
Agreement. Any such vote shall be cast in accordance with such procedures
relating thereto so as to ensure that it is duly counted for purposes of
determining that a quorum is present and for purposes of recording the results
of such vote. Each Stockholder agrees not to enter into any agreement or
commitment with any Person the effect of which would be inconsistent with or
violative of the provisions and agreements contained in this Section 3(a).

        (b)         Each Stockholder agrees not to, directly or indirectly, (i)
sell, transfer, tender, pledge, encumber, assign or otherwise dispose of
(collectively, a “Transfer”) or enter into any Contract, agreement, option or
other arrangement with respect to a Transfer, or consent to a Transfer of, or
enter into a Constructive Sale (as defined below) with respect to, any or all of
the Subject Shares, other than in accordance with the Merger Agreement, or (ii)
grant any powers of attorney or consents, grant any proxies (other than the
Company proxy card in connection with the Company Stockholders’ Meeting if and
to the extent such proxy is consistent with such Stockholder’s obligations under
Section 3(a) hereof), deposit any Subject Shares into any voting trust or enter
into any voting arrangement, whether by proxy, voting agreement or otherwise,
with respect to any of the Subject Shares, other than pursuant to this Agreement
or in a manner consistent with such Stockholder’s obligations under Section 3(a)
hereof. Such Stockholder further agrees not to commit or agree to take any of
the foregoing actions or take any action that would in any way prevent, impede,
interfere with or adversely affect his ability to perform his obligations under
this Agreement. Notwithstanding the foregoing or anything to the contrary set
forth in this Agreement, each Stockholder may Transfer any or all of the Subject
Shares (1) by will, or by operation of law, in which case this Agreement shall
bind the transferee, or (2) to A) Stockholders’ spouse, children, parents or
siblings (collectively, “Family Members”), (B) any trust solely for the benefit
of Stockholder and/or any Family Member(s) and of which Stockholder and/or any
such Family Member(s) is the trustee or are the trustees, and (C) any
partnership, corporation or limited liability company which is wholly owned and
controlled by Stockholder and/or any such Family Member(s), so long as the
transferee, prior to such Transfer, executes a counterpart of this Agreement
(with such modifications as Parent may reasonably request solely to reflect such
transfer) and the Proxy, substantially in the form of Annex A hereto. As used
herein, the term “Constructive Sale” shall mean a short sale with respect to any
Subject Shares, entering into or acquiring an offsetting derivative contract
with respect to any Subject Shares, entering into or acquiring a futures or
forward contract to deliver any Subject Shares or entering into any other
derivative transaction that has the effect of materially changing the economic
benefits and risks of ownership.

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

        (c)         Such Stockholder shall not, nor shall such Stockholder act
in concert with any Person to make, or in any manner participate in, directly or
indirectly, a “solicitation” (as such term is used in the rules of the
Securities and Exchange Commission) of proxies or powers of attorney or similar
rights to vote.

        (d)         In the event (i) of any stock dividend, stock split, merger,
recapitalization, reclassification, combination, exchange of shares or the like
of the capital stock of the Company on, of or affecting the Subject Shares or
(ii) that Stockholder shall become the beneficial owner of any additional shares
of capital stock of the Company or other securities entitling the holder thereof
to vote or give consent with respect to the matters set forth in Section 3(a),
then the terms of this Agreement shall apply to the shares of capital stock of
the Company or other securities held by Stockholder immediately following the
effectiveness of the events described in clause (i) or Stockholder becoming the
beneficial owner thereof as described in clause (ii), as though, in either case,
they were Subject Shares hereunder.

        (e)        Proxy.

                     (i)         In furtherance of the transactions contemplated
hereby and by the Merger Agreement, and in order to secure the performance by
Stockholder of Stockholder’s duties under this Agreement, Stockholder,
concurrently with the execution of this Agreement, shall execute, in accordance
with the provisions of applicable law, and deliver to Parent an irrevocable
proxy, substantially in the form of Annex A hereto, and irrevocably appoint
Parent or its designees, with full power of substitution, Stockholder’s attorney
and proxy to vote, or, if applicable, to give consent with respect to, all of
the Subject Shares beneficially owned by Stockholder as of the record date of
such vote or consent in respect of any of the matters set forth in, and in
accordance with the provisions of, Section 3(a) (the “Proxy”).

                     (ii)         Stockholder understands and acknowledges that
Parent is entering into the Merger Agreement in reliance upon such Proxy.
Stockholder hereby affirms that the Proxy set forth in this Section 3(d) is
given to secure the performance of the duties of Stockholder under this
Agreement. Stockholder hereby affirms that the Proxy is coupled with an interest
and may under no circumstances be revoked. Stockholder hereby ratifies and
confirms all that the Proxy may lawfully do or cause to be done by virtue
hereof.

                     (iii)         Stockholder hereby revokes any and all prior
proxies or powers of attorney given by Stockholder with respect to the voting of
the Subject Shares and agrees not to grant any subsequent proxies or powers of
attorney with respect to the voting of the Subject Shares until the termination
of this Agreement in accordance with Section 5.

                     (iv)         Stockholder shall, at Stockholder’s own
expense, perform such further acts and execute such further proxies and other
documents and instruments as may reasonably be required to vest in Parent the
power to carry out and give effect to the provisions of this Agreement.

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

                     (v)         The Proxy shall terminate upon the termination
of this Agreement.

        4.        Stockholder Capacity.

        No Person executing this Agreement who is or becomes during the term of
this Agreement a director or officer of the Company shall be deemed to make any
agreement or understanding in this Agreement in such Person’s capacity as a
director or officer. Each Stockholder is entering into this Agreement solely in
his capacity as the beneficial owner of such Stockholder’s Subject Shares and
nothing herein shall limit or affect in any way any actions taken by a
Stockholder in his capacity as a director or officer of the Company.

        5.        Termination.

        This Agreement shall terminate upon the earliest to occur of: (i) the
approval and adoption of the Merger Agreement at the Company Stockholders’
Meeting; (ii) the termination of the Merger Agreement in accordance with its
terms; or (iii) the Parent providing a notice of termination to the
Stockholders. No party hereto shall be relieved from any liability for
intentional breach of this Agreement by reason of any such termination.
Notwithstanding the foregoing, this Section 5 and Sections 7 and 8 of this
Agreement shall survive the termination of this Agreement.

        6.        Appraisal Rights.

        To the extent permitted by applicable law, each Stockholder hereby
waives and agrees not exercise any rights of appraisal or rights to dissent from
the Merger that he may have with respect to the Subject Shares under applicable
law.

        7.        Publication.

        Each Stockholder hereby authorizes Parent and the Company to publish and
disclose in the Proxy Statement (including any and all documents and schedules
filed with the Securities and Exchange Commission relating thereto) his identity
and ownership of Subject Shares and the nature of his commitments, arrangements
and understandings pursuant to this Agreement.

        8.        Waiver of Jury Trial.

        EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY THAT MAY ARISE
UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES AND
THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY
RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION
DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE
TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. EACH PARTY CERTIFIES AND
ACKNOWLEDGES THAT (A) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY
HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE
EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (B) EACH SUCH PARTY
UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (C) EACH SUCH
PARTY MAKES THIS WAIVER VOLUNTARILY, AND (D) EACH SUCH PARTY HAS BEEN INDUCED TO
ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND
CERTIFICATIONS IN THIS SECTION 8.

6

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

        9.        Governing Law; Jurisdiction.

        This Agreement shall be governed by, and construed in accordance with,
the laws of the State of Delaware applicable to contracts executed in and to be
performed entirely within that State. Each party hereby agrees and consents to
be subject to the exclusive jurisdiction of the Court of Chancery of the State
of Delaware in and for New Castle County or, if the Court of Chancery lacks
subject matter jurisdiction, any court of the State of Delaware situated in New
Castle County or the United States District Court for the District of Delaware
in any suit, action or proceeding seeking to enforce any provision of, or based
on any matter arising out of or in connection with, this Agreement or the
transactions contemplated hereby. Each party hereby irrevocably consents to the
service of any and all process in any such suit, action or proceeding by the
delivery of such process to such party at the address and in the manner provided
in Section 13 hereof. Each of the parties hereto irrevocably and unconditionally
waives any objection to the laying of venue of any action, suit or proceeding
arising out of this Agreement or the transactions contemplated hereby in the
Court of Chancery of the State of Delaware in and for New Castle County or, if
the Court of Chancery lacks subject matter jurisdiction, any court of the State
of Delaware situated in New Castle County or the United States District Court
for the District of Delaware, and hereby further irrevocably and unconditionally
waives and agrees not to plead or claim in any such court that any such action,
suit or proceeding brought in any such court has been brought in an inconvenient
forum.

        10.        Specific Performance.

        Stockholder acknowledges that the agreements contained in this Agreement
are an integral part of the transactions contemplated by the Merger Agreement,
and that, without these agreements, Parent would not enter into the Merger
Agreement, and acknowledges that money damages would be both incalculable and an
insufficient remedy for any breach of this Agreement by such party and that any
such breach would cause the other party hereto irreparable harm. Accordingly,
each party hereto also agrees that, in the event of any breach or threatened
breach of the provisions of this Agreement by such party, the other party hereto
shall be entitled to equitable relief without the requirement of posting a bond
or other security, including in the form of injunctions and orders for specific
performance.

        11.        Amendment, Waivers, Etc.

        This Agreement may be amended by Parent, Merger Sub and the Stockholders
at any time before adoption of the Merger Agreement by the stockholders of the
Company; provided, however, that after such adoption, no amendment shall be made
that by law or in accordance with the rules of any relevant stock exchange or
automated inter-dealer quotation system requires further approval by such
Stockholders without such further approval. This Agreement may not be amended
except by an instrument in writing signed by Parent, Merger Sub and the
Stockholders. At any time prior to the Effective Time, Parent, Merger Sub and
the Stockholders may, to the extent legally allowed, (i) extend the time for the
performance of any of the obligations or acts of the other party; (ii) waive any
inaccuracies in the representations and warranties of the other party contained
herein or in any document delivered pursuant to this Agreement; and (iii) waive
compliance with any of the agreements or conditions of the other party contained
herein; provided, however, that no failure or delay by Parent, Merger Sub and
the Stockholders in exercising any right hereunder shall operate as a waiver
thereof nor shall any single or partial exercise thereof preclude any other or
further exercise thereof or the exercise of any other right hereunder. Any
agreement on the part of Parent or the Stockholders to any such extension or
waiver shall be valid only if set forth in an instrument in writing signed on
behalf of such party.

        12.        Assignment; No Third Party Beneficiaries.

hereunder may be assigned by any of the parties hereto (whether by operation of
law or otherwise) without the prior written consent of all of the other parties.
Subject to the preceding sentence, this Agreement will be binding upon, inure to
the benefit of and be enforceable by the parties hereto and their respective
successors and permitted assigns. Nothing in this Agreement, express or implied,
is intended to or shall confer upon any Person (other than Parent, Merger Sub
and the Stockholders and their respective successors and permitted assigns) any
legal or equitable right, benefit or remedy of any nature whatsoever under or by
reason of this Agreement, and no Person (other than as so specified) shall be
deemed a third party beneficiary under or by reason of this Agreement.
