member of the Board of Directors of Parent or from taking any action with
respect to any Acquisition Proposal as an officer or member of such Board of
Directors.
8.    Miscellaneous.
(a)    Entire Agreement. This Agreement (together with any and all schedules and
exhibits hereto) constitutes the entire agreement among the parties hereto with
respect to the subject matter hereof and supersedes all other prior agreements
and understandings, both written and oral, among the parties hereto with respect

action as may be necessary or desirable to consummate and make effective, in the
most expeditious manner practicable, the transactions contemplated hereby.

the Stockholder and any of its designees any proxies, including with respect to

Agreement.
(d)    No Assignment. This Agreement shall not be assigned by operation of law
or otherwise without the prior written consent of the Parent Holders (in the
case of any assignment by the Stockholder) or the Stockholder (in the case of an
assignment by any Parent Holder); provided that the Stockholder may assign its
rights and obligations hereunder to the Company or any other Subsidiary of the
Stockholder, but no such assignment shall relieve the Stockholder of its
obligations hereunder.

have hereunder in respect of any Transfer of the Covered Shares, the Parent
Holders agree that this Agreement and the obligations hereunder shall attach to
the Covered Shares beneficially owned by the Parent Holders and their respective
affiliates and shall be binding upon any person to which legal or beneficial
ownership of such Covered Shares shall pass, whether by operation of law or
otherwise, including, without limitation, the Parent Holder’s heirs, guardians,
administrators, representatives or successors.
