Agreement or (y) related to the transactions contemplated by the Merger
Agreement or this Agreement, the Shareholder shall not, directly or indirectly,
grant any Person any proxy (revocable or irrevocable), power of attorney or
other authorization with respect to the voting of any of the Subject Shares.

SECTION 3.    Agreement to Vote Shares.
(a)
Voting Agreement. Until the Expiration Date, at every meeting of shareholders of
the Company called with respect to any of the following, and at every
adjournment or postponement thereof, and on every action or approval by written
consent of shareholders of the Company with respect to any of the following, the
Shareholder agrees (solely in its capacity as a shareholder of the Company) that
it shall, or shall cause its nominee holder of record on any applicable record
date to, (x) appear at such meeting or otherwise cause the Subject Shares that
are eligible to be voted at such shareholder meeting to be counted as present
thereat for purposes of establishing a quorum and (y) vote the Subject Shares
that the Shareholder is eligible to vote at any applicable general or special
meeting of the shareholders of the Company, or deliver a written consent in
respect of the Subject Shares if action is being taken by written consent of the
shareholders of the Company:

(i)
in favor of (x) adoption of the Merger Agreement and approval of the Merger and
the other transactions and any other actions necessary, desirable, or reasonably
requested by Parent in furtherance thereof, (y) in favor of any proposal to
adjourn a meeting of the stockholders of the Company to solicit additional
proxies in favor of the adoption of the Merger Agreement and approval of the
Merger and the other transactions, and (z) any proposal or action in respect of
which approval of the Company’s shareholders is requested that could reasonably
be expected to facilitate the Merger and the other transactions contemplated by
the Merger Agreement; and

(ii)
against (x) any proposal or action that would constitute, or could reasonably be
expected to result in, a breach of any covenant, representation or warranty or
any other obligation or agreement of the Company under the Merger Agreement or
of the Shareholder under this Agreement or otherwise reasonably would 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, (y) any Acquisition Proposal or any proposal relating to an
Acquisition Proposal and (z) any stock purchase agreement, merger,
consolidation, combination, sale of substantial assets, reorganization,
recapitalization, dissolution, liquidation or winding up of or by the Company
(other than the Merger Agreement);

provided, that the foregoing voting covenants shall apply solely to actions
taken by the Shareholder in its capacity as a shareholder of the Company, and
solely with respect to such matters to the extent the approval of the Company’s
shareholders is required or requested of the Company’s shareholders by the
Company, and the Shareholder shall not have any obligations or restrictions with
respect to such matters in any other capacity or in any other context.
Notwithstanding anything herein to the contrary, this Section 3 shall not
require the Shareholder to be present (in person or by proxy) or vote (or cause
to be voted) any of its Subject Shares to amend the Merger Agreement or take any
action that could result in the amendment or modification, or a waiver of a
provision therein, in any such case, in a manner that (x) decreases the amount
or changes the form of the consideration or imposes any restrictions or
additional conditions on the receipt of the consideration to the stockholders of
the Company or (y) is otherwise materially adverse to the Shareholder. The
Shareholder shall retain at all times the right to vote its Subject Shares in
its sole discretion and without any other limitation on those matters other than
those set forth in clauses (i) and (ii) above that are at any time or from time
to time presented for consideration to the Company’s stockholders generally. For
the avoidance of doubt, clauses (i) and (ii) above shall not apply to votes, if
any, solely on the election or removal of directors as recommended by the
Company Board (provided such recommendation is not in violation of the terms of
the Merger Agreement).
SECTION 4.    No Ownership Interest. Nothing contained in this Agreement shall
be deemed to vest in Parent any direct or indirect ownership or incidence of
ownership of, or with respect to, any Subject Shares. All rights, ownership and
economic benefits of and relating to the Subject Shares shall remain vested in
and belong to the Shareholder, and this Agreement shall not confer any right,
power or authority upon Parent or any other Person (a) to direct the Shareholder
in the voting of any of the Subject Shares, except as otherwise specifically
provided herein, or (b) in the performance of any of the Shareholder’s duties or
responsibilities as shareholders or officers or directors, as the case may be,
of the Company. Notwithstanding anything in this Agreement to the contrary,
nothing herein shall require the Shareholder to exercise any option and/or other
rights to purchase Company Capital Stock (including Company Options).
SECTION 5.    Solicitation. The Shareholder hereby represents and warrants that
the Shareholder has read Section 5.2 of the Merger Agreement. In addition, the
Shareholder, solely in the Shareholder’s capacity as a shareholder of the
Company, agrees not to, directly or indirectly, take any action that would
violate Section 5.2 of the Merger Agreement if the Shareholder were deemed a
“Representative” of the Company for purposes of such Section 5.2 of the Merger
Agreement; provided, the foregoing shall not serve to limit or restrict any
actions taken by the Shareholder in any capacity other than as a shareholder of
the Company, to the extent such actions are permitted or required under such
Section 5.2 of the Merger Agreement.
SECTION 6.    Representations, Warranties and Other Agreements of the
Shareholder. The Shareholder hereby represents and warrants to Parent as of the
date hereof:
(a)
(i) the Shareholder is the beneficial owner of, and has good, valid and
marketable title to, the Subject Shares and Subject Options set forth opposite

beneficially, by the Shareholder as of the date hereof (other than equity
securities of the Company held in family trusts), (iv) the Subject Shares and
Subject Options owned by the Shareholder are free and clear of all Liens, other
than Permitted Liens, any Liens created by this Agreement, the underlying

securities Laws and (iv) the Shareholder has not appointed or granted any proxy
inconsistent with this Agreement, which appointment or grant is still effective,
with respect to the Subject Shares;

(c)
the Shareholder agrees not to bring, commence, institute, maintain, prosecute,
participate in or voluntarily aid any action, claim, suit or cause of action, in
law or in equity, in any court or before any Governmental Authority, which
alleges that (i) the execution and delivery of this Agreement by the Shareholder
and the granting of any proxies to be delivered in connection with the execution
of the Merger Agreement, or (ii) the approval of the Merger Agreement by the
Company Board, breaches any fiduciary duty of the Company Board or any member
thereof;

(d)
the execution and delivery of this Agreement by the Shareholder does not, and
the performance of this Agreement by the Shareholder will not, result in a
violation or breach of, or constitute (with or without due notice or lapse of
time or both) a default (or give rise to any right of termination, cancellation,
modification or acceleration) (whether after the giving of notice of or the
passage of time or both) under any applicable Law or any contract to which the
Shareholder is a party or which is binding on the Shareholder or the Subject
Shares or Subject Options, and will not result in the creation of any Lien on
any of the Subject Shares or Subject Options;

(e)
this Agreement has been duly executed by the Shareholder and constitutes the
valid and legally binding obligation of the Shareholder, enforceable against the
Shareholder in accordance with its terms, except that such enforceability

affecting or relating to the enforcement of creditors’ rights generally and
(ii) is subject to general principles of equity, whether considered in a
proceeding at law or in equity;

(f)
the execution and delivery of this Agreement by the Shareholder does not, and
the performance of this Agreement by the Shareholder will not, require any
consent, approval, authorization or permit of, or filing with or notification
to, any Governmental Authority by the Shareholder, (i) except for any applicable
requirements, if any, of the Exchange Act and the HSR Act, any applicable
foreign antitrust, competition or merger control applicable Laws, and any CFIUS
filings and (ii) except where the failure to obtain such consents, approvals,
authorizations or permits, or to make such filings or notifications, would not
prevent or delay the performance by the Shareholder of the Shareholder’s
obligations under this Agreement in any material respect;

(g)
as of the date of this Agreement, there are no Legal Proceedings pending, or to
the knowledge of the Shareholder, threatened against the Shareholder or any of
the Shareholder’s assets or properties that would reasonably be expected to
impair the Shareholder’s ability to perform the Shareholder’s obligations under
this Agreement on a timely basis; and

(h)
the Shareholder understands and acknowledges that Parent is entering into the
Merger Agreement in reliance upon the Shareholder’s execution and delivery of
this Agreement and the representations and warranties of the Shareholder
contained herein.

SECTION 7.    Consent. The Shareholder on behalf of itself only consents to and
authorizes the Company, Parent and their respective Affiliates (and Parent
authorizes the Company and its Affiliates) to (a) publish and disclose in the
Proxy Statement, any current report of the Company on Form 8-K and any other
documents required to be filed with the SEC or any regulatory authority in
connection with the Merger Agreement, the Shareholder’s identity and ownership
of Subject Shares and Subject Options and the nature of the Shareholder’s
commitments, arrangements and understandings under this Agreement (“Shareholder
Information”) and (b) file this Agreement as an exhibit to the extent required
to be filed with the SEC or any regulatory authority relating to the Merger. The
Shareholder hereby agrees to cooperate with Parent and the Company in connection
with such filings, including providing such Shareholder Information reasonably
requested by Parent or the Company. As promptly as reasonably practicable, the
Shareholder shall notify Parent of any required corrections with respect to any
Shareholder Information supplied by the Shareholder, if and to the extent the
Shareholder becomes aware that any such Shareholder Information shall have
become false or misleading in any material respect.
SECTION 8.    Shareholder Capacity. To the extent that the Shareholder is an
officer or director of the Company or any Subsidiaries of the Company, nothing
in this Agreement shall be construed as preventing or otherwise affecting any
deliberations or actions taken or not taken by the Shareholder in its capacity
as an officer or director of the Company or any Subsidiaries of the Company or
from fulfilling the duties and obligations of such office (including the
performance of obligations required by the fiduciary duties of the Shareholder
acting in its capacity as an officer or director), and none of such
deliberations or actions (or determinations not to take any action) in such
other capacities shall be deemed to constitute a breach of this Agreement. For
the avoidance of doubt, nothing in this Agreement shall limit in any way the
Company or its officers or directors from taking actions permitted or required
by the Merger Agreement and Parent shall not assert any claim that any action
taken by the Shareholder in its capacity as a director or officer of the Company

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON
VOTING, TRANSFER AND CERTAIN OTHER LIMITATIONS SET FORTH IN THAT CERTAIN

hereunder automatically shall terminate and be of no further force or effect as
of the Expiration Date; provided, that upon termination of this Agreement,
Parent shall take such actions as are reasonably requested by the Shareholder to
remove any legend placed upon any Subject Shares pursuant to Section 9 (and to
cause the return of any certificates evidencing Subject Shares to the extent
provided by the beneficial owner thereof to Parent or any of its Affiliates);
provided, further, however, (a) Section 11 and Section 13 shall survive any
termination or expiration of this Agreement, (b) any such termination shall not
relieve any party from liability for any willful breach of its obligations
hereunder prior to such termination, and (c) each party will be entitled to any
remedies at law or in equity to recover its losses arising from any such
pre-termination willful breach of its obligations hereunder.
SECTION 11.    Appraisal Rights. The Shareholder (i) irrevocably waives and
agrees not to exercise, assert or perfect any rights to appraisal with respect
to any of the Subject Shares or rights to dissent from the Merger that the
Shareholder may have and (ii) agrees not to commence or participate in, and will
take all actions necessary to opt out of, any class in any class action with
respect to, any claim, derivative or otherwise, against Parent, Guarantor,
Merger Sub, the Company or any of their respective successors relating to the
negotiation, execution or delivery of this Agreement or the Merger Agreement or
the consummation of the Merger, including any claim (x) challenging the validity
of, seeking to enjoin the operation of, any provision of this Agreement or (y)
alleging a breach of any fiduciary duty of the Company Board in connection with
the Merger Agreement or the transactions contemplated thereby; provided, that
the foregoing covenants shall not be deemed a consent to or waiver of any rights
of the Shareholder for any breach of this Agreement by Parent or its Affiliates.
SECTION 12.    Further Assurances.
(a)
Each of the parties hereto shall execute and deliver any additional certificate,
instruments and other documents, and take any additional actions, as any other
party reasonably may deem necessary or appropriate to carry out and effectuate

The Shareholder agrees, while this Agreement is in effect, to notify Parent
promptly in writing of the number and description of any Subject Shares or
Subject Options acquired by the Shareholder after the date hereof which are not
set forth on Schedule I hereto.

SECTION 13.    Miscellaneous.
(a)
Expenses. All costs and expenses incurred in connection with this Agreement
shall be paid by the party incurring such cost or expense.

(b)
Waiver. No failure or delay by the Parent in exercising any right, power or
privilege under this Agreement or applicable Law shall operate as a waiver of
such rights nor shall any single or partial exercise thereof preclude any other
or further exercise of any other right, power or privilege hereunder (except as
otherwise specifically set forth herein).

(c)
Severability. The provisions of this Agreement shall be deemed severable and the
illegality, invalidity or unenforceability of any provisions shall not affect
the legality, validity or enforceability of the other provisions of this
Agreement. In the event that any provision of this Agreement, or the application
thereof, becomes or is declared by a court of competent jurisdiction to be
illegal, invalid or unenforceable, (i) the remainder of this Agreement will
continue in full force and effect, (ii) the application of such provision to
other persons or circumstances shall not be affected by such illegality,
invalidity or unenforceability and (iii) the Parties will negotiate reasonably
and in good faith agree to replace such illegal, invalid or unenforceable
provision of this Agreement with a suitable and equitable provision that will
achieve, to the extent possible, the economic, business and other intent and
purposes of such illegal, invalid or unenforceable provision.

(d)
Assignment. No party may assign either this Agreement or any of its rights or
interests or obligations hereunder, in whole or part, by operation of Law or
otherwise, without the prior written approval of the other parties and any
attempted or purported assignment or delegation in violation of this Section
13(d) shall be null and void. Subject to the preceding sentence, this Agreement
shall be binding upon and shall inure to the benefit of the parties and their
respective successors and permitted assigns.

(e)
Amendments. This Agreement may not be modified, amended, altered or
supplemented, except upon the execution and delivery of a written agreement
executed by each of the parties hereto.

(f)
Specific Performance; Injunctive Relief. The parties agree that irreparable
damage would occur to Parent in the event that any provision of this Agreement
were not performed by the Shareholder in accordance with the specific terms
hereof, and that Parent shall be entitled to an injunction, specific performance
and other equitable relief to prevent breaches or threatened breaches of this
Agreement and to enforce specifically the terms and provisions hereof, this
being in addition to any other remedy to which Parent is entitled at law or in
equity. The Shareholder agrees that it will not oppose the granting of an
injunction, specific performance and other equitable relief to enforce the
covenants and obligations contained herein on the basis that Parent has an
adequate remedy at law or an award of specific performance is not an appropriate
remedy for any reason at law or equity and Parent shall not be required to post
a bond or other security in connection with any such order or injunction.

(g)
Governing Law. This Agreement, and all Legal Proceedings arising out of or
relating to this Agreement, or the negotiation, validity or performance of this
Agreement or the Transactions, shall be deemed to be made in and in all respects
shall be governed by and interpreted and construed in accordance with the Laws
of the State of Delaware, regardless of the Laws that might otherwise govern
under applicable principles of conflicts of law thereof (or any other
jurisdiction) to the extent that such Laws would direct a matter to another
jurisdiction.

(h)
Jurisdiction and Venue. Each of the Shareholder and Parent hereby irrevocably
and unconditionally (i) consents to submit to the sole and exclusive
jurisdiction of the Selected Courts for any litigation arising out of or
relating to this Agreement, or the negotiation, validity or performance of this
Agreement, or the transactions contemplated hereby, (ii) agrees not to commence
any litigation relating thereto except in such courts, (iii) waives any
objection to the laying of venue of any such litigation in such courts and (iv)
agrees not to plead or claim in such courts that such litigation brought therein
has been brought in any inconvenient forum. Without limiting the foregoing, each
party agrees that service of process on it by notice as provided in Section
13(l) shall be deemed effective service of process.

(i)
Waiver of Trial by Jury. EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY ACTION OR
PROCEEDING ARISING OUT OF OR RELATING TO 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 SUCH ACTION OR PROCEEDING. 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 SUCH ACTION OR PROCEEDING, SEEK TO ENFORCE THE FOREGOING WAIVER; (B) IT
UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER; (C) IT MAKES
THIS WAIVER VOLUNTARILY; AND (D) IT HAS BEEN INDUCED TO ENTER INTO THIS
AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS
SECTION 13(i).

(j)
No Agreement Until Transaction Documents Executed. Irrespective of negotiations
among the parties or the exchanging of drafts of this Agreement, this Agreement
shall not constitute, or be deemed to evidence, a contract, agreement,
arrangement or understanding between the parties hereto unless (i) the Merger
Agreement is executed and delivered by all parties thereto and (ii) this
Agreement is executed and delivered by all parties hereto.

(k)
No Third Party Beneficiaries. This Agreement is not intended, and shall not be
deemed, to confer any rights or remedies upon any person other than the parties

agreement of employment with any person or to otherwise create any third-party
beneficiary hereto.
