                  CANWEST GLOBAL COMMUNICATIONS CORP LETTERHEAD

December 2, 2002

                                                               WITHOUT PREJUDICE

PRIVATE & CONFIDENTIAL

Mr. Bob Calvert
Executive Vice President
Southam Publications Inc.
44 Fairford Street West
Moose Jaw, SK  S6H 6E4

Dear Bob:

I write this letter with mixed feelings. We all will be sorry to lose you, but
we must respect your wish to leave, since you are not interested in taking on
the position of regional head of the Company's Saskatchewan media properties.
This letter, therefore, concerns the terms of the termination of your employment
with Southam Publications Inc. (the "Company").

As you are aware, the Company has an agreement with G.T.C. Transcontinental
Group Limited ("GTC") that it is obligated to honour. This agreement requires us
to continue to employ you at least until the first anniversary of the closing
date of the transaction with GTC, being August 9, 2003. Any change to this
agreement will have to be made with the knowledge and consent of GTC. However,
it is likely that GTC will not object to your ceasing to be employed by the
Company prior to August 9, 2003, provided you do not take up employment with a
competitor during this period. Should the terms of this letter be acceptable to
you, we will endeavour to confirm their position.

The terms of separation the Company is offering you are as follows:

1.    In recognition of our expecting to complete further divestitures of
      community papers this calendar year, on January 1, 2003, your duties and
      responsibilities will diminish. Accordingly, as "working notice" in lieu
      of severance, unless your employment is terminated earlier in accordance
      with this letter, on December 31, 2004 (being twenty-four (24) months from
      January 1, 2003) (the "Separation Date"), you will cease working for the
      Company and your employment will come to an end.

2.    Between now and December 31, 2004 (the "Salary Continuance Period"), you
      will continue to be employed by the Company and will perform those duties
      for which you are currently responsible. However, as noted, we acknowledge
      that, as a consequence of the divestiture of the Atlantic

<PAGE>

                                       2

      community papers and possibly more divestitures, your responsibilities may
      be diminished and/or new projects or assignments may be undertaken by you.
      During the Salary Continuance Period and, subject to the terms of this
      letter, you will be entitled to seek new employment opportunities. If
      during the Salary Continuance Period you obtain full-time employment or
      independent contractor status (collectively, "Replacement Status"), or if
      the Company determines, either respective party may terminate your
      employment on seven (7) days' notice. The effective date of any such
      termination shall be deemed to be the Separation Date (and replaces the
      date referred to in paragraph 1) for the purposes of this letter.

3.    Provided you have not contravened the provisions of paragraph 4 of this
      letter and notwithstanding either party may terminate your employment as
      noted above during the Salary Continuance Period but subject to paragraph
      5, you will be paid your current monthly base salary in the form of salary
      continuance (the "Salary Continuance"), payable in accordance with the
      Company's payroll schedule, subject to applicable statutory remittances
      and deductions.

4.    While you are free to accept new employment outside the Company at any
      time, the Company reserves the right, in its sole discretion, to preclude
      you, during the Salary Continuance Period, from working or being engaged
      in, either as an employee or independent contractor, advisor, financial
      supporter or investor in Canada in the business of the publication,
      distribution or sale of any print newspaper (or any section thereof,
      including classified or job advertisements) or other print publications or
      the distribution of flyers, inserts or the printing of any product of any
      kind (each, a "Competitive Activity"), and you agree not to engage in any
      Competitive Activity without the express prior written consent of the
      Company, which consent may be withheld by it in its absolute discretion.
      This prohibition will not prevent or restrict you from acquiring and
      holding as a personal investment, in the aggregate, less than one (1%)
      percent of the shares of any publicly traded corporation.

5.    Subject to paragraph 4 hereof, in the event you attain Replacement Status
      during the Salary Continuance Period, the bi-monthly payments comprising
      the Salary Continuance will be reduced to an amount equal to the
      difference between your new bi-monthly salary or income and the bi-monthly
      amount of your Salary Continuance, for the then remaining balance of the
      Salary Continuance Period. In other words, the Company would "top up" your
      new salary or income to the level of the Salary Continuance amount
      referred to in paragraph 3 above, for the then remaining balance of the
      Salary Continuance Period. In the case of your new salary or income being
      greater than the level of your Salary Continuance, then the Salary
      Continuance would cease upon the effective date of your attaining
      Replacement Status.

                                       3

6.    You will be paid promptly, once it is determined, your bonus entitlement
      (if any) for the Company's fiscal year ending August 31, 2002. Your bonus
      entitlement will be determined in accordance with the current criteria and
      practice used for establishing same.

7.    At the end of the Salary Continuance Period, and provided you have not
      contravened the provisions of paragraph 4 of this letter, the Company will
      pay you a single lump sum retirement allowance of $100,000.00 (the
      "Retirement Allowance").

8.    To the extent permitted by the relevant legislation, the Salary
      Continuance payments and the Retirement Allowance will be paid, if
      directed in writing by you, to your RRSP as a "retirement allowance".
      Should you die prior to receiving the full Salary Continuance payments and
      Retirement Allowance, any unpaid portions thereof shall be paid to your
      estate, in accordance with the terms of this agreement.

9.    The Company will continue to provide you with health, group life and AD&D
      benefits for a period ending on the earlier of the expiration of the
      Salary Continuance Period and your attaining Replacement Status. You will
      continue to be a participant in the Company's long-term disability plan
      for a period expiring on the earlier of eight (8) weeks following the
      Separation Date and your attaining Replacement Status; such that any
      qualifying disability experienced by you during this period will be
      covered. The current premium cost sharing between the Company and yourself
      in respect of the foregoing benefits and plan will remain the same as if
      you continued to be employed by the Company. Short-term disability and
      out-of-Canada emergency health coverage will not be provided following the
      Separation Date.

10.   The Company will pay all outstanding vacation entitlement within thirty
      (30) days of the Separation Date.

11.   Your current car allowance of $1,127.00 per month and reimbursement or
      payment in full of fuel for your leased vehicle will continue to be paid
      by the Company for a period ending on the earlier of the expiration of the
      Salary Continuance Period and your attaining Replacement Status. As well,
      the Company will reimburse you for the cost of two (2) golf memberships
      for the period ending on the earlier of the expiration of the Salary
      Continuance Period and your attaining Replacement Status.

12.   You are entitled to retirement benefits under your pension plan with the
      Company. You will be credited with active years of service until the
      earlier of the Separation Date and your attaining Replacement Status. Kim
      Miller (Vice President, Human Resources of CanWest Global Communications
      Corp. ("CanWest")) will be available to discuss the options available to
      you in receiving these retirement benefits.

<PAGE>

                                       4

13.   Except as noted above, no other benefits, bonuses or allowances will be
      paid to you by the Company.

14.   We will require the prompt return of all Company property in your
      possession and any outstanding employee or executive loans payable by you
      to be repaid in full on the earlier of the Separation Date and your
      attaining Replacement Status.

15.   During the Salary Continuance Period and for a period of twelve (12)
      months thereafter, you shall not directly or indirectly contact, approach
      or solicit for the purposes of offering employment to any person (whether
      as an employee, consultant, agent, independent contractor or otherwise)
      who is employed by or providing services to the Company or any of its
      affiliates, without the prior written consent of the Company, unless the
      employee has been dismissed by the Company.

16.   You agree, for an indefinite period, not to, in any manner, provide,
      engage in, or participate privately or publicly and either directly or
      indirectly in, any analysis, assessment, criticism or commentary, of
      CanWest's or the Company's policies and practices, including, without
      limitation, its editorial practices and policies.

17.   In the course of providing your duties, you may have had access to and may
      have been entrusted with trade secrets, trademarks or other proprietary
      and confidential information and knowledge, including, but not limited to,
      business plans, data, documents, budgets, correspondence, strategic plans,
      private or internal business discussions involving one or more executives
      and papers and records, concerning the present and contemplated activities
      of, or to be evolved and used by the Company and its affiliated
      corporations ("Confidential Information"), the disclosure of any such
      Confidential Information in any manner would be highly detrimental to the
      interests of the Company and/or its affiliates. You agree that the right
      to maintain such Confidential Information constitutes a proprietary right,
      which the Company and its affiliates have the right to protect.
      Accordingly, you agree with the Company that you will not disclose, or
      permit (either during the continuance of your employment or at any time
      thereafter) the disclosure of any such Confidential Information to any
      person, or permit the use of the same for any purposes other than those of
      the Company. All files, records, recordings, documents, equipment or other
      items relating to the business of the Company and its affiliates, whether
      prepared by you or otherwise coming into your possession, shall remain the
      exclusive property of the Company and shall not be removed from the
      Company's premises without the Company's written consent, and shall be
      returned by you to the Company upon request. The foregoing restriction
      shall not restrict you from applying your general skill and aptitude in
      any endeavour or employment.

18.   In accepting this letter, you acknowledge either having received
      independent legal advise in respect of the terms and content of this
      letter or having waived seeking and obtaining such independent legal
      advise.

19.   Subject to the foregoing, upon your acceptance of this letter, you hereby
      release the Company and its affiliates, successors, assigns, directors and
      employees from and forever compromise any and all claims and demands
      whatsoever, whether monetary or otherwise, including claims for damages,
      wages, salary, commissions, bonuses, and other remuneration, as well as
      any benefits or sums due under the Company or its affiliates' plans or
      policies, and also from all manner of action or actions, suit or suits,
      complaint or complaints, cause or causes of action, whether before any
      judicial or quasi-judicial or administrative tribunal or otherwise, which
      you now have, ever had or can or may have, against the Company in respect
      of your employment with the Company and any predecessor employer for which
      the Company may be responsible or a successor employer, and separation
      thereof, or any cause, matter or thing arising out of or connected
      therewith, save and except the terms of this letter and any right or
      entitlement you have under any applicable pension or retirement plan.

The foregoing is an offer to accommodate your desire to voluntarily separate
from the Company, as outlined above, and shall remain open for acceptance by you
for three (3) weeks following the date of this letter. The terms of this letter
shall supersede and replace all other provisions in any prior or existing
employment agreement or arrangement with the Company or any predecessor
employer, save and except the terms of any applicable pension or retirement plan
currently existing in your favour.

Yours sincerely,

CANWEST GLOBAL COMMUNICATIONS CORP.
