Re: Agreement dated December 14, 1999 (“Agreement”) by and between CTV
Television Inc. (“CTV”) and
Blue Zone Productions Ltd. (“Blue Zone”)

Further to several conversations between our respective organizations with
respect to the above referenced Agreement, I wish to confirm our agreement:

LICENSE TO BLUE ZONE INTELLECTUAL PROPERTY

1.     Blue Zone hereby grants, effective as of September 21, 2001, to CTV a
non-exclusive, worldwide license (the “License”) to use the Blue Zone
Intellectual Property for the purposes described in Section 5(d)(1) of the
Agreement for the period commencing on September 21, 2001 and continuing until
September 20, 2002 (the “License Period”). For certainty, all representations,
warranties and indemnities of Blue Zone set out in the Agreement and which are
applicable to the license of the Blue Zone Intellectual Property shall continue
to apply to the License granted herein, notwithstanding the termination or
expiration of such Agreement.

For purposes of this letter agreement, it is acknowledged and agreed that the
permitted uses of the License granted as described above shall include all
current uses by CTV of the Blue Zone Intellectual Property.

2.     Section 13 of the Agreement is deleted in its entirety.

Unless earlier terminated in accordance with this Item 2 or unless renewed by
mutual written agreement of the parties, the Agreement will terminate on
December 31, 2001 without obligation for either party to give notice. Either
party may terminate the Agreement, the License and this letter agreement
immediately by written notice to the other party if:

--------------------------------------------------------------------------------

 

(a)   the other party becomes insolvent or makes an assignment for the benefit
of creditors generally, or a petition in bankruptcy is filed against the other
party, or proceedings are taken to wind up the other party or if a receiver or
receiver-manager is appointed for the other party or any of its assets; or

(b)   the other party defaults in the performance of any of its material
obligations under this letter agreement or the Agreement, and fails to remedy
that default within 30 days after receipt from the non-defaulting party of
written notice specifying the default.

(c)   the parties have not agreed upon a form of Escrow Agreement, made CTV a
beneficiary under the Escrow Agreement and deposited the Deposited Material with
the Agent as provided in Item 7 below before October 28, 2001, except where the
reason for the failure was outside of the control of CTV.

Notwithstanding the foregoing, the fact that CTV terminates the Agreement or the
Letter Agreement as a result of Blue Zone becoming insolvent, making an
assignment for the benefit of creditors generally, having a petition in
bankruptcy filed against it, taking proceedings to wind up, or having a receiver
or receiver-manager appointed for it, will not terminate the License or relieve
Blue Zone or its successors from its obligations pursuant to Sections 7, 8 and
9.

The License and this letter agreement will automatically terminate without
obligation of either party to give notice on September 20, 2002 unless
terminated earlier according to the provisions herein or extended by mutual
agreement of the parties. Sections 5 (a), (c)(1) and c(2), (e), (g), (h), 6, 10,
15 of the Agreement shall survive termination of the Agreement. Items 2, 3, 4
(other than Section 4(b), 8, 9 and 10 of this letter agreement will survive
termination of the letter agreement.

3.     The License shall not be subject to CTV acquiring or retaining any Web
management or hosting services from Blue Zone. In this regard the provisions
related to the management and hosting of the CTV Web Site set out in the
Agreement (including for certainty Section 4 of the Agreement) shall,
notwithstanding anything to the contrary in the Agreement, be terminated
effective as of October 1, 2001 and, as of such date, neither party shall have
any further obligations or rights under the Agreement with respect to same.

4.     In consideration for the License for the License Period as described in
Item 1, CTV shall pay to Blue Zone an amount equal to one hundred and twenty
thousand dollars ($120,000) Cdn. funds, (the “License Fee”) payable as follows:

  (a)   $60,000 Cdn funds payable immediately upon execution of this letter
agreement, by wire transfer to a Blue Zone bank account, the details of which
will be provided to CTV by Blue Zone in writing; and

  (b)   the remaining $60,000 Cdn. funds payable immediately upon execution of
the Escrow Agreement (as described below) and written confirmation of deposit of
the Deposited Materials with the Agent.

The License fees payable under this Item 4 are non-refundable, notwithstanding
termination of this letter agreement.

SUPPORT SERVICES

5.     For the month of October, Blue Zone will continue to provide to CTV the
support as contemplated in the Maintenance and Service Level Agreement by and
between the parties dated June 1, 2001 (the “SLA”). CTV will pay to Blue Zone on
October 1, 2001: (a) 50% of the Monthly Fee owing under the SLA less the
accumulated credits calculated pursuant to Section 3 of the SLA for
unavailability in the month of September; and (b) by no later than November 5,
2001, the balance of the amount owing for the support provided by Blue Zone
during the month of October, less any additional credits to which CTV may be
entitled pursuant to Section 3 of the SLA for unavailability in the month of
October.

CTV hereby notifies Blue Zone, and Blue Zone hereby acknowledges and agrees,
that CTV does not wish to renew the SLA for the period after October 31, 2001
and that accordingly the SLA will be terminated effective October 31, 2001.

CTV shall pay to Blue Zone an amount equal to twenty four thousand, four hundred
and eighty-nine dollars and twenty cents ($24,489.20) Cdn. funds, as net payment
for the fees owing under the SLA for the period between September 1, 2001 and
September 30, 2001 after deducting all credits which CTV may be entitled to
pursuant to Section 3 of the SLA for any unavailability which may have arisen
prior to September 1, 2001. Such funds will be payable immediately upon
execution of this letter agreement, by wire transfer to a Blue Zone bank
account, the details of which will be provided to CTV by Blue Zone in writing.

6.     Commencing on November 1, 2001, Blue Zone agrees to provide to CTV
technical and operational support (the “Support”) related to the Blue Zone
Intellectual Property to CTV on a monthly basis. The Support shall consist of:
(i) the provision of upgrades, bug fixes and patches for the Blue Zone
Intellectual Property (excluding labour); (ii) on-call support availability with
maximum 1 hour call-back response time each day during the hours of 07:00
(EST) to 24:00 (EST); (iii) on-call support availability with maximum 2 hour
call-back response time each day during the hours of 24:00 (EST) to 07:00 (EST);
and (iv) such other details and support levels as mutually agreed to by the
parties, acting reasonably and negotiating in good faith. Blue Zone will make
reasonable commercial efforts to promptly resolve material problems and errors
with the Blue Zone Intellectual Property which are within its control provided
that it receives all necessary assistance from CTV. For clarity, the response
times referred to above are not guarantees of resolution times of any problem or
error with the Blue Zone Intellectual Property. In consideration for such
Support, CTV agrees to pay to Blue Zone a fee (the “Support Fee”) of four
thousand dollars ($4,000) Cdn. funds per month plus all applicable taxes.

Blue Zone acknowledges and agrees that CTV may terminate such Support
arrangements upon thirty (30) days written notice to Blue Zone.

ESCROW ARRANGEMENT

7.     The parties agree to use best efforts and to negotiate in good faith to
conclude a source code escrow agreement (the “Escrow Agreement”) for the Blue
Zone Intellectual Property by September 28, 2001 or as soon as possible
thereafter.

The Escrow Agreement will include terms which: (a) require Blue Zone to deposit
with an industry recognized escrow agent (the “Agent”), to be held in escrow,
the source code (in human readable form) for all of the Blue Zone Intellectual
Property (the “Deposited Material”); (b) require Blue Zone to update the
Deposited Material each and every instance where there is a material change to
the Deposited Material made by Blue Zone or its designate (including all
material bug fixes, any updates, any upgrade or any other enhancements); and
(c) authorize and require the Agent to transfer and make available the Deposited
Material to CTV for use by CTV only for the purpose of continuing the benefits
afforded to CTV pursuant to the License and support related to the Blue Zone
Intellectual Property as contemplated by this letter agreement in the event of,
and only for such period of time as, any of the following conditions exist,
including: (i) Blue Zone filing for bankruptcy or seeking similar relief under
any applicable law; (ii) a receiver, trustee or similar officer being appointed
for the business or property of Blue Zone; or (iii) any involuntary petition or
proceeding under bankruptcy or insolvency laws being instituted against Blue
Zone and not stayed, enjoined, contested or discharged within thirty (30) days;
or (iv) Blue Zone failing to carry on business in the ordinary course
(collectively, the “Release Conditions”), provided that CTV provide the Agent
and Blue Zone with an acknowledgement that it will only use the Deposited
Material in accordance with this Item 7 and the License.

Upon the discontinuance or removal of any of the Release Conditions, CTV will
destroy or return to the Agent all of the Deposited Materials and any copies
thereof and provide Blue Zone with an officer’s certificate to that effect and
CTV will thereafter have no right to use any of the Deposited Materials.

The fees and expenses for the foregoing escrow arrangement described in this
Item 7 shall be borne by Blue Zone. The Escrow Agreement will provide that in
the event that the Agent will not act where Blue Zone does not pay any fees and
expenses due to the Agent under the Escrow Agreement, CTV may pay such fees and
expenses and Blue Zone will immediately reimburse CTV.

8.     The parties agree that the arrangement contemplated herein is binding on
the parties, shall be governed by the laws of the Province of Ontario and shall
enure to the benefit of their respective successors and permitted assigns.

9.     In connection with the planned migration of hardware associated with the
CTV Web Site, Blue Zone hereby agrees to provide to CTV all necessary passwords
and other reasonable assistance to effect an orderly and seamless migration at
Blue Zone standard hourly rates.

10.     For clarity, unless the context otherwise requires, all capitalized
terms used herein shall have the meaning set out in the Agreement. Further, in
the event of a conflict between the terms and conditions of this letter
agreement and the terms and conditions set out in the Agreement, the terms and
conditions of this letter agreement shall prevail and apply.

This letter agreement is a written, binding amendment to the Agreement as
contemplated by Section 15(g) of the Agreement.
