By accepting this Option grant and exercising any portion of your Option, you
agree to comply with all the terms of the Plan and this notification.

The Plan is discretionary in nature and may be amended, cancelled, or terminated
at any time. The grant of Options is a one-time benefit offered solely to
employees of Convedia Corporation ("Convedia"), a wholly-owned subsidiary of the
Company, and does not create any contractual or other right to receive a grant
of Options or benefits in lieu of Options in the future.

Your Option may not be assigned, sold, encumbered, or in any way transferred or
alienated.

Options covered by this Grant Notice may have certain tax consequences at the
time of exercise. You are encouraged to obtain independent tax advice before
exercising any Options.

Vesting and the duration of your Option are both subject to your continual
employment with the Company or one of its subsidiaries. Vesting will stop and
your Options will automatically expire three months after termination of your
employment with the Company or one of its subsidiaries.



                                                                            U.S.

Your Option is not transferable, does not imply any right to continued
employment and may be exercised only by you.
