intent, on the part of the Corporation or a Subsidiary, to extend the
employment of any Employee beyond the time at which such Employee would
normally be required to retire in accordance with any applicable
employment agreement, or retirement plan or policy of the Corporation or
a Subsidiary, then in effect.

|     |  | If any Option has terminated or expired without being fully exercised,
any unissued Shares which have been reserved to be issued upon the
exercise of the Option shall become available to be issued upon the
exercise of Options subsequently granted under the Plan.

|     |  | No fractional shares shall be issued upon the exercise of an Option nor
shall any scrip certificates in lieu therefore be issuable at any time.
Accordingly, if as a result of any adjustment under Section 3.7, a
Participant would otherwise have become entitled to a fractional share
upon the exercise of an Option, the Participant shall have the right to
purchase only the next lower whole number of Shares and no payment or
other adjustment will be made with respect to the fractional interest so
disregarded.

|    
|     |  | The Board may revoke the designation of a corporation as a Subsidiary, so
long as such revocation does not have retroactive effect. For the
purposes of section 4.4, the Service Termination Date of a Participant
who is an Employee of such corporation shall be deemed to be the date of
such revocation.

administrators or personal or legal representatives may exercise an
Option by delivering: (i) a written notice of exercise in the form

|     |  | Subject to Section 4.8, an Option granted under this Plan shall be
transferable only by will or by the laws of intestacy and shall be
exercisable, during the lifetime of the Participant to whom the Option is
granted, only by the Participant (or, during any period in which the
Participant lacks capacity, by the Participants personal or legal
representatives) and, upon the death of the Participant, by the
Participants heirs, executors, administrators or personal or legal
representatives. No Option and none of the rights and privileges thereby
conferred shall be transferred, assigned, pledged, hypothecated in any
way or made the subject of any security of any kind whatever (whether by
operation of law or otherwise), and no Option and none of the rights and
privileges thereby conferred shall be subject to execution, attachment or
similar process. Upon any attempt by a Participant to so transfer,
assign, pledge, hypothecate, make subject to a security or otherwise
dispose of an Option or any of the rights and privileges thereby
conferred contrary to the provisions hereof, or upon the levy of any
execution, attachment or similar process upon an Option or any of the
rights and privileges thereby conferred, the Option and such rights and
privileges shall immediately terminate and cease to be exercisable.
