    (b)           Each
Stockholder retains at all times the right to vote such Stockholder’s Covered

attorney-in-fact and proxy, with full power of substitution, for and in such
Stockholder’s name, to vote, express consent or dissent, or otherwise to utilize
such voting power in the manner contemplated by Section 3.01(a) as such
attorney-in-fact and proxy, in his or her sole discretion, deems proper with
respect to such Stockholder’s Covered Shares.  Except as otherwise
expressly set forth in this Section 3.02, this Proxy is irrevocable

Stockholder.  The proxy granted by such Stockholder pursuant to this

terms.  Such Stockholder hereby revokes any and all previous proxies
granted with respect to its Covered Shares.

     

    Section 3.03No

contract or agreement with respect to any transfer of such Covered Shares or any
interest therein, (iii) grant or permit the grant of any proxy, power of
attorney or other authorization in or with respect to such Covered Shares, (iv)

limit or interfere with the performance of such Stockholder’s obligations
hereunder or the transactions contemplated hereby or otherwise make any
representation or warranty of such Stockholder herein untrue or
incorrect.

     

    (b)           Any
attempted transfer of Covered Shares, or any interest therein, in violation of
this Section 3.03 shall be null and void.  In furtherance of this
Agreement, such Stockholder shall and hereby does authorize the Company, and the
Company hereby agrees, to notify the Company’s transfer agent that there is a
stop transfer restriction with respect to all of its Covered Shares and that
this Agreement places limits on the voting and transfer of such Stockholder’s
Covered Shares; provided that any such stop transfer restriction shall terminate
automatically, without any notice or other action by any Person, upon the
termination of this Agreement in accordance with Section 4.03 and, upon

Agreement may be signed in any number of counterparts, each of which shall be an
original, with the same effect as if the signatures thereto and hereto were upon

any other Stockholder has or does execute this Agreement.

     

    Section 4.12Entire
Agreement.  This

with respect to the subject matter of this Agreement and supersedes all prior
agreements and understandings, both oral and written, between the parties with
respect to its subject matter.

     

    Section

any term, provision, covenant or restriction of this Agreement is held by a
court of competent jurisdiction or other Governmental Authority to be invalid,
void or unenforceable, the remainder of the terms, provisions, covenants and
restrictions of this Agreement shall remain in full force and effect and shall
in no way be affected, impaired or invalidated so long as the economic or legal
substance of the transactions contemplated hereby is not affected in any manner
materially adverse to any party.  Upon such a determination, this
Agreement shall be modified so as to affect the original intent of the parties
as closely as possible in an acceptable manner in order that the transactions
contemplated hereby be consummated as originally contemplated to the fullest
extent possible.

not have an adequate remedy at law for money damages in such
event.  Accordingly, each of Parent and Merger Sub shall be entitled
to specific performance and injunctive and other equitable relief to prevent

performance of the terms and provisions hereof by each Stockholder, in addition
to any other remedy to which they are entitled at law or in equity.

from acting in such capacity.  This Agreement shall apply to each
Stockholder solely in each Stockholder’s capacity as a holder of the Covered
Shares.

     

    Section
4.16Stockholder Obligations Several and not Joint.  The
obligations of each Stockholder hereunder shall be several and not joint and no
Stockholder shall be liable for any breach of the terms of this Agreement by any
other Stockholder.
