Stockholder of all documents or instruments required to be delivered pursuant to

consummation of the Merger, (B) disclosed such determination in the
Schedule 14D-9 or other written materials distributed to all Company

under the Merger Agreement, unless this Agreement shall have terminated pursuant
to Section 5.2, Stockholder shall not, directly or indirectly, (a) create or

would restrict, limit or interfere in any material respect with the performance
of any of Stockholder’s obligations under this Agreement.  Notwithstanding the
foregoing, Stockholder may make Transfers of Subject Shares (i) by will, (ii) by
operation of Law, (iii) for estate planning purposes, (iv) for charitable
purposes or as charitable gifts or donations or (v) to any of its Affiliates, in
