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 participation in the Plan is voluntary. The value of the Company Option is
an extraordinary item of compensation outside the scope of your employment
contract, if any. As such, the Option is not part of normal or expected
compensation for purposes of calculating any severance, resignation, redundancy,
end of service payments, bonuses, long-service awards, pension, or retirement
benefits or similar payments.

The future value of the underlying Shares of the Company's Common Stock is
unknown and cannot be predicted with certainty. If the Company Common Stock
underlying your Options does not increase in value, or if such Common Stock
decreases in value, the Options will have no value.

You are responsible for obtaining all necessary exchange control approvals or
making filings, where required, in order to remit payment for the purchase price
of Shares subject to the Option to the Company.

You acknowledge and consent to the collection, use, processing and transfer of
personal data as described in this paragraph. You understand that the Company
and its subsidiaries hold certain

personal information about you, including your name, home address and telephone
number, date of birth, social security number, social insurance number or other
employee identification number, salary, nationality, job title, any Shares of
Common Stock or directorships held in the Company, details of all Options or any
other entitlement to Shares of Common Stock awarded, canceled, purchased,
vested, unvested or outstanding in your favor, for the purpose of managing and
administering the Plan ("Data"). You further understand that the Company and/or
its subsidiaries will transfer Data amongst themselves as necessary for the
purpose of implementation, administration and management of your participation
in the Plan, and that the Company and/or any of its subsidiaries may each
further transfer Data to any third parties assisting the Company in the
implementation, administration and management of the Plan. You understand that
these recipients may be located in the United States and elsewhere. You
authorize them to receive, possess, use, retain and transfer the Data, in
electronic or other form, for the purposes of implementing, administering and
managing your participation in the Plan, including any requisite transfer of
such Data as may be required for the administration of the Plan and/or the
subsequent holding of Shares of Common Stock on your behalf to a broker or other
third party with whom you may elect to deposit any Shares of Common Stock
acquired pursuant to the Plan. You understand and further authorize the Company
and/or any of its subsidiaries to keep Data in your personnel file. You also
understand that you may, at any time, review Data, require any necessary
amendments to Data or withdraw the consents herein in writing by contacting the
Company. You further understand that withdrawing your consent may affect your
ability to participate in the Plan.

You will have no entitlement to compensation or damages in consequence of the
termination of your employment by the Company or any of its subsidiaries for any
reason whatsoever and whether or not in breach of contract, insofar as such
entitlement arises or may arise from your ceasing to have rights under or to be
entitled to vest in any Options as a result of such termination or from the loss
or diminution in value of the same and, upon grant, you will be deemed
irrevocably to have waived such entitlement.

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

The Plan is governed by and subject to U.S. law. Interpretation of the Plan and
your rights under the Plan will be governed by provisions of U.S. law.

Options covered by this Option 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 any of its subsidiaries. Vesting will stop and
your Options will automatically expire three months after termination of your
employment with the Company or any of its subsidiaries. Your Option is not
transferable, does not imply any right to continued employment and may be
exercised only by you.

By signing below, you acknowledge all of the above as well as that you have
received the Plan document, this Option Notice and prospectus and agree that
your participation in the Plan is governed by the terms and conditions set forth
in the Plan document and this Option Notice, and to the extent not inconsistent,
the prospectus.
