and “controlled by” have correlative meaning.

“Change in Control” means the occurrence of any one or more of the following
events or conditions:

(i) any “person” or any “group” (as such terms are used in Sections 13(d) and

the total combined voting power of the Company’s Voting Securities;

(ii) the consummation of a merger, consolidation, share exchange or similar form
of corporate reorganization of the Company, or any such type of transaction
involving the Company or any of its Subsidiaries that requires the approval of
the Company’s shareholders (whether for such transaction or the issuance of
securities in the transaction or otherwise), or the sale or other disposition in
one transaction or a series of transactions of all or substantially all of the
assets of the Company (any of the foregoing events being referred to herein as a
“Business Combination”), unless such Business Combination also constitutes a
Non-Control Transaction (as defined below);

(iii) individuals constituting the Board as of August 1, 2006 (the “Incumbent
Board”) cease for any reason to constitute at least a majority of the Board (or
the board of directors or similar governing body of the surviving entity or its
ultimate parent company in the case of a merger, consolidation or reorganization
of the Company whose principal purpose is to change the Company’s state of
incorporation, form a holding company or effect a similar reorganization as to
form); provided, however, that any individual whose election to the Board, or
whose nomination for election to the Board by the Company’s stockholders, was

the corporation or other entity resulting from such Business Combination
(including a corporation or other entity that acquires all or substantially all
of the assets of the Company or that beneficially owns, directly or indirectly,
100% of the Company’s Voting Securities) or the ultimate parent company thereof
is represented by shares that comprised Voting Securities of the Company
immediately prior to such Business Combination (either by remaining outstanding
or by being converted), and such voting power is in substantially the same
proportion as the voting power of such Voting Securities of the Company
immediately prior to such Business Combination; and

(ii) at least a majority of the members of the board of directors or equivalent
governing body of the corporation or other entity resulting from such Business
Combination or the ultimate parent company thereof were Incumbent Directors at
the time of the Board’s approval of the initial agreement providing for such
Business Combination.

“Plan” means this Plan as defined in Section 1 hereof, as the same may be
modified, amended or supplemented from time to time in accordance with the terms
hereof.

“Subsidiary” means any entity, domestic or foreign, of which not less than 50
percent of the outstanding Voting Securities are owned or controlled, directly
or indirectly, by the Company, whether or not such entity now exists or is
hereafter organized or acquired.
