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.

You agree that your participation in the Plan is voluntary, and that you have
not been induced to accept this grant by expectation of employment or continued
employment with the Company, Convedia or any other subsidiary of the Company.
You further covenant that you are an employee in active employment with
Convedia.

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.



                                                                          Canada

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. Any reference in the Plan or in
this Option Notice to the time when you "terminate employment" or words of
similar import shall be a reference to the time when you cease to be in active
employment with the Company and all of its subsidiaries and, for such purpose,
if the Company or any of its subsidiaries has made payment in lieu of notice to
you or has dismissed you with or without notice, you shall cease to be in active
employment with the Company and all of its subsidiaries on the date when the
Company or any of its subsidiaries required you to stop reporting to work.

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.
Notwithstanding the foregoing, you acknowledge that the tax laws of Canada will
also apply to you in respect of the Plan and this Option Notice.

You agree that you will comply with all Applicable Laws in connection with this
Option grant and the acquisition and sale of any Shares of Common Stock of the
Company issued hereunder and will indemnify and hold the Company and all of its
subsidiaries harmless from and against any loss, cost or expense incurred by the
Company or any of its subsidiaries in connection with any breach or default
under such Applicable Laws.

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. By signing below, you acknowledge that you have received
independent legal counsel or have decided, voluntarily without influence from
the Company or any of its subsidiaries, that you do not need to seek such
independent legal advice in relation to this Option Notice, the Plan and all
related documents.

You will be liable for any and all U.S. and Canadian federal, state, provincial
or local taxes, pension plan contributions, employment insurance premiums and
other levies of any kind required by law to be



                                                                          Canada

deducted or withheld with respect to the grant and exercise of this Option
(collectively, the "Withholding Taxes"). You acknowledge that the Company and
Convedia shall have the right to deduct and withhold all required Withholding
Taxes from any Shares, payment or other consideration deliverable to you. The
Company may, prior to and as a condition of issuing any Shares pursuant to the
exercise of this Option, require you to pay any required Withholding Taxes or to
satisfy the Company in a manner acceptable to the Company that any required
Withholding Taxes will be paid.

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.
