4.1   The Executive shall receive an annual base salary in an amount not less

      shall include the portions thereof paid in periodic installments and the
      so-called forced savings amount payable in one annual installment),

      salary that have been in effect since October 3, 2003 (herein, the "Base

      statements of the Corporation for the immediately preceding year, and may,
      at any time, review and at its discretion adjust, the amount of the Base
      Salary; provided, however, that the amount of Base Salary in any year
      shall in no event be less than the Base Salary paid or payable to the
      Executive during any previous year of his employment with the Corporation.

                                    ARTICLE V

      during the term of this agreement, in such amount, if any, and at such
      time(s) as shall be determined pursuant to the Corporation's bonus plan
      for senior executives of the Corporation; and (b) until such time as the

                                   ARTICLE vi
                           TREATMENT OF STOCK OPTIONS

6.1   Should the Executive's employment be terminated by the Corporation without
      Cause or by the Executive with Good

<PAGE>

      Reason, before the announcement of a transaction or event constituting a
      Change of Control, or should the Executive's employment be terminated by
      the Executive for any reason (whether with or without Good Reason)
      following the completion of a transaction or event constituting a Change
      of Control, or should the Executive's employment be terminated by the
      Corporation for any reason (whether with or without Cause) following the
      announcement of a transaction or event constituting a Change of Control,
      all options to purchase shares of the Corporation then held by the
      Executive (collectively, "Options") shall vest immediately upon the
      termination of the Executive's employment and, subject to obtaining any
      required regulatory approvals and further subject to Section 6.2, shall
      remain exercisable for the remainder of the original term thereof.

6.2   The Corporation shall be required to use its reasonable efforts to obtain
      within 75 days following the date of any termination of the Executive's
      employment referred to in Section 6.1 (the "Termination Date"), any
      regulatory approvals that are required to permit all Options to remain
      exercisable for the remainder of the original term thereof notwithstanding
      such termination of employment; provided, however, that the Corporation
      shall have no obligation to seek any shareholder approval that might be
      established by the applicable regulatory authority as a condition
      precedent to the grant of any such regulatory approval. If for any reason
      such regulatory approvals are not obtained by such date, the Executive
      shall (to the extent that he has not already done so), exercise all
      in-the-money Options on or prior to the 90th day (the "Calculation Date")
      after the Termination Date and the Corporation shall pay to the Executive
      on the day following the Calculation Date, in a lump sum (less any
      statutory deductions at source), an amount equal to the fair market value
      of the Options determined as of the Termination Date and as if the Options
      remained exercisable in full for the remainder of the original term
      thereof, less the amount of the Gain (as hereinafter defined) realized by
      the Executive upon his exercise of such in-

<PAGE>

      the-money Options. For the purposes of this Section 6.2, the Gain realized
      by the Executive upon his exercise of such in-the-money Options shall
      equal the difference between a) the aggregate exercise price of such
      in-the-money Options and b) to the extent any of the shares underlying the
      Options are sold on or prior to the Calculation Date, the proceeds from
      such sale net of any brokerage commission, and to the extent such shares
      are not sold by the Calculation Date, the average closing price for the
      Class "A" shares of Optimal on the principal market or exchange on which
      such shares are traded, over the five trading days ending on the
      Calculation Date (and including the Calculation Date, if such market or
      exchange is open for trading on such date).

      The fair market value of the Options shall be determined by the auditors
      of the Corporation, at the expense of the Corporation, on or prior to the
      Calculation Date, by using the Black-Scholes valuation model and such
      assumptions for use in such model as are reasonable and appropriate in
      their professional judgment (such fair market value determination
      hereinafter called the "Determination"). Before making the Determination,
      the auditors shall give the Executive the opportunity to be heard and to
      present the opinion of his professional advisors at his expense. A copy of
      the Determination and the related calculations shall be provided promptly
      to the Executive and such Determination shall be final and binding upon
      the parties and not subject to appeal.

                                   ARTICLE VII
                              BENEFITS AND VACATION

7.1   The Executive shall participate in all benefit programs and/or plans of
      general application which are presently granted or which, at any time
      during his employment, may be granted to senior executives of the
      Corporation, the whole in accordance with the actual programs or plans
      that the Corporation may institute from time to time or as otherwise
      required under any applicable law.

<PAGE>

7.2   All business expenses incurred by the Executive during his employment in
      connection with the performance of his duties shall be reimbursed by the
      Corporation upon submission of invoices or other supporting documentation
      in accordance with company policy.

7.3   The Executive shall be entitled to such number of paid vacation days per
      fiscal year of the Corporation as shall be in keeping with the vacation
      policy of the Corporation as it applies to its senior executive officers,
      to be taken at such times and intervals as shall be determined by the
      Executive, subject to the reasonable business needs of the Corporation.

7.4   During the term of this Agreement, the Corporation shall, in addition to
      any other insurance coverage provided to the Executive in his capacity as
      an officer of the Corporation, pay or reimburse to the Executive or his
      designee the cost of the reasonable premiums associated with a personal
      life and disability insurance policy with a minimum coverage of
      US$5,000,000 (or the Canadian dollar equivalent thereof) in term or whole
      life insurance, which policy shall be owned by the Executive or his
      designee.

7.5   All legal, accounting and other expenses incurred by the Executive to
      successfully recover any amount or enforce performance of any other
      obligation due to him by the Corporation shall be reimbursed by the
      Corporation within ten (10) days of the presentation of appropriate
      supporting documents.

                                  ARTICLE VIII

      limitation, all notes, extracts, text or references from which any
      Confidential Information can be implicitly or otherwise revealed or
      understood) shall be deemed to be Confidential Information within the
      meaning of this Agreement and shall be treated as such.

8.3   Confidential Information and all embodiments thereof (including any
      reproduction) shall remain the sole property of the Corporation and shall
      be returned to the Corporation immediately upon request to this effect or
      immediately after the termination of the Executive's employment.

8.4   Anything to the contrary herein notwithstanding, disclosure of
      Confidential Information shall not be precluded if such disclosure is in
      response to a valid order of a governmental body or is otherwise required
      by law; provided however that the Executive shall, if reasonably possible,
      first have given notice thereof to the Corporation and shall have, as
      reasonably possible:

      (a)   fully cooperated in the Corporation's attempt, if any, to obtain a
            "protective order" from the appropriate governmental body; or

      (b)   attempted to classify such documents to prevent access by the
            public, in accordance with the provisions of any law pertaining to
            freedom of information.
