consent or other approval is sought, such Stockholder shall vote the Company
Shares owned beneficially or of record by such Stockholder as follows:

(i) in favor of adoption of the Merger Agreement, and approval of the terms

any other circumstances upon which such Stockholder’s vote, consent or other
approval is sought, such Stockholder shall vote the Parent Shares owned
beneficially or of record by such Stockholder as follows:

(i) to approve the issuance of the Merger Consideration; and

(ii) other than in the case of a Parent Acquisition Proposal, against any action
or agreement that has or would reasonably be likely to result in any conditions
to Parent’s and Merger Sub’s obligations under Article VII of the Merger
Agreement not being satisfied.

(c) Grant of Company Shares Proxy. Each Stockholder hereby irrevocably grants to
and appoints, Parent and each of its designees (the “Parent Authorized Parties”
and each a “Parent Authorized Party”), and each of them individually, as the
Stockholder’s proxy and attorney-in-fact (with full power of substitution) for
and in the name, place and stead of the Stockholder, to vote the Company Shares
or execute one or more written consents or approvals in respect of the Company
Shares:

(i) in favor of adoption of the Merger Agreement, and approval of the terms
thereof and of the Merger, and the other transactions contemplated thereby;

(ii) against any action or agreement that has or would reasonably be expected to
result in any conditions to the Company’s obligations under Article VII of the
Merger Agreement not being satisfied;

(iii) against any Company Acquisition Proposal;

(iv) against any amendments to the Company Charter and/or the Company Bylaws if
such amendment would reasonably be expected to prevent or materially delay the
consummation of the Closing; and

(v) against any other action or agreement that is intended, or would reasonably
be expected to, impede, interfere with, delay, or postpone the Merger or the
transactions contemplated by the Merger Agreement or change in any manner the
voting rights of any class of stock of the Company;

in each case, if and only if such Stockholder (1) fails to vote, or (2) attempts
to vote (whether by proxy, in person or by written consent), in a manner which
is inconsistent with the terms of this Agreement.

(d) Grant of Parent Shares Proxy. Each Stockholder hereby irrevocably grants to
and appoints, the Company and each of its designees (the “Company Authorized
Parties” and each a “Company Authorized Party”), and each of them individually,
as the Stockholder’s proxy and attorney-in-fact (with full power of
substitution) for and in the name, place and stead of such Stockholder, to vote
the Parent Shares or execute one or more written consents or approvals in
respect of the Parent Shares:

 

5

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

(i) to approve the issuance of the Merger Consideration; and

(ii) other than in the case of a Parent Acquisition Proposal, against any action
or agreement that has or would reasonably be likely to result in any conditions
to Parent’s and Merger Sub’s obligations under Article VII of the Merger
Agreement not being satisfied;

in each case, if and only if such Stockholder (1) fails to vote, or (2) attempts
to vote (whether by proxy, in person or by written consent), in a manner which
is inconsistent with the terms of this Agreement.

(e) Each Stockholder hereby ratifies and confirms that the irrevocable proxies
set forth in Sections 4(c) and (d) are given in connection with the execution of
the Merger Agreement and that such irrevocable proxy is given to secure the
performance of such Stockholder’s duties in accordance with this Agreement. Each
Stockholder hereby further ratifies and confirms that the irrevocable proxies
granted hereby are coupled with an interest and may under no circumstances be
revoked, except as otherwise provided in this Agreement. Such irrevocable
proxies shall be valid until termination of this Agreement. The powers of
attorney granted by such Stockholder herein are durable powers of attorney and
shall survive the dissolution, bankruptcy, death or incapacity of such
Stockholder. Upon the execution of this Agreement, such Stockholder hereby
revokes any and all prior proxies or powers of attorney given by the Stockholder
with respect to voting of the Company Shares or the Parent Shares on the matters
contemplated hereby and agrees not to grant any subsequent proxies or powers of
attorney with respect to the voting of the Company Shares or the Parent Shares
on the matters contemplated hereby until after the termination of this
Agreement. Each Stockholder understands and acknowledges that each of Parent and
the Company is entering into the Merger Agreement in reliance upon such
Stockholder’s execution and delivery of this Agreement and such Stockholder’s
granting of the proxies contained in Sections 4(c) and (d). Each Stockholder
hereby affirms that the proxies granted in Section 4(c) and (d) are given in
connection with the execution of the Merger Agreement, and that such proxies are
given to secure the performance of the duties of such Stockholder under this
Agreement. If for any reason a proxy granted herein is found by a court of
competent jurisdiction to not be valid, then the Stockholder agrees to vote the
Parent Shares or the Company Shares, as applicable, in accordance with
Section 4(a) or Section 4(a), as applicable. For Company Shares as to which such
Stockholder is the beneficial but not the record owner, such Stockholder shall
take all necessary actions to cause any record owner of such Company Shares to
irrevocably constitute and appoint Parent and its designees as such record
owner’s attorney and proxy and grant an irrevocable proxy to the same effect as
that contained herein. For Parent Shares as to which such Stockholder is the
beneficial but not the record owner, the Stockholder shall take all necessary
actions to cause any record owner of such Parent Shares to irrevocably
constitute and appoint the Company and its designees as such record owner’s
attorney and proxy and grant an irrevocable proxy to the same effect as that
contained herein. The parties acknowledge and agree that none of Parent or the
Company or their respective successors, assigns, subsidiaries, divisions,
employees, officers, directors, stockholders, agents and affiliates shall owe
any duty to, whether in law or otherwise, or incur any liability of any kind
whatsoever, including without limitation, with respect to any and all claims,
losses, demands, causes of action, costs, expenses (including attorney’s fees)
and compensation of any kind or nature whatsoever to such Stockholder in
connection with or as a

(f) Other Voting. Each Stockholder may vote on all issues other than those
specified in this Section 4 that may come before a meeting of the stockholders
of the Company or the shareholders of Parent, as the case may be, in its sole
discretion, provided that such vote does not contravene the provisions of this
Section 4.

contrary herein, each Stockholder shall be entitled to participate with the
Company and its directors, officers, representatives, advisors or other
intermediaries in any negotiations or discussions with any Person (including,

that would be entered into at any time after the termination of this Agreement),

Acquisition Proposal or a Superior Proposal.

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

(d) Assignment. Without the prior written consent of the other party to this
Agreement, no party may assign any rights or delegate any obligations under this
Agreement. Any such purported assignment or delegation made without prior
consent of the other party hereto shall be null and void.

(e) Parties in Interest. This Agreement shall be binding upon, inure solely to
the benefit of, and be enforceable by, the parties hereto and their successors

benefit or remedy of any nature whatsoever under or by reason of this Agreement.

(f) Amendment. This Agreement may not be amended except by an instrument in
writing signed by the parties hereto.

(g) Severability. If any term or other provision of this Agreement is invalid,
illegal or incapable of being enforced by any rule of law, or public policy, all

full force and effect so long as the economic or legal substance of this
Agreement is not affected in any manner materially adverse to any party. Upon
such determination that any term or other provision is invalid, illegal or
incapable of being enforced, the parties hereto shall negotiate in good faith to
modify this Agreement so as to effect the original intent of the parties as
closely as possible in a mutually acceptable manner in order that the terms of
this Agreement remain as originally contemplated to the fullest extent possible.
