ACE Aviation Holdings Inc. Employee Share Purchase Plan
Notes to Financial Statements
December 31, 2005
- -------------------------------------------------------------------------------

(in Canadian dollars)

1.       Description of the Plan

         The following description of the ACE Aviation Holdings Inc. Employee
         Share Purchase Plan (the "Plan") is provided for general information
         purposes only. The plan document should be referred to for more
         complete information.

               a)   General

                    The Plan was created on February 8, 2005 and is a defined
                    contribution savings plan for substantially all employees
                    of ACE Aviation Holdings Inc. and its participating
                    subsidiaries and affiliates (collectively, the "Company" or
                    the "Employer").

                    The Plan is administered by Computershare Trust Company of
                    Canada ("Computershare"), appointed as the Administrative
                    Agent by the Company. The Plan's assets are held, invested,
                    managed, administered and dealt with by Computershare
                    pursuant to the terms of the Plan. A trust fund was
                    established for all contributions made by the Company under
                    the Plan. The Company appointed Computershare as the
                    Trustee of the trust to hold, invest and administer the
                    trust fund. Computershare, as Administrative Agent and
                    Trustee shall maintain a member account to record
                    contributions received and shares held in respect of each
                    member.

                    Certain administrative functions are performed by employees
                    of ACE Aviation Holdings Inc. and its subsidiaries. No
                    employee receives compensation from the Plan.

               b)   Participation

                    All employees of the Company in North America are eligible
                    to participate, provided that the employee has completed a
                    six-month period or more of continuous service.

               c)   Contributions

                    Under the provisions of the Plan, employees may contribute
                    2%-6% of their gross annual salary. In the case of
                    employees whose salary is paid in a currency other than
                    Canadian dollars, the Canadian dollar equivalent of their
                    selected yearly member contributions shall be determined on
                    the basis of the exchange rate on the first of each month.

                    For any employee contributions made during the months of
                    March, April, and May 2005 (the "Special Member
                    Contributions"), the Company remitted a special
                    contribution (the "Special Company Contributions") equal to
                    50% of such Special Member Contributions to the Trustee to
                    be held in trust on behalf of each employee ("Member"). The
                    Special Company Contributions made to the Trust Fund shall
                    be held, invested, managed, administered and dealt with by
                    the Trustee in the same manner as the assets of the Plan
                    are to be held, invested, managed, administered and dealt
                    with by the Administrative Agent pursuant to the terms of
                    the Plan.

                    On the first business day of April following the end of the
                    Plan year, the Company will make a contribution of 33 1/3%
                    of the amount contributed by the Member during the Plan
                    year reduced by: (i) the Special Member Contributions, if
                    any, and (ii) any withdrawal amounts as of the first day of
                    April following the end of the Plan year allocated to such
                    year of contribution.

               d)   Investments

                    All Member contributions and Company Contributions to the
                    Plan as well as all dividends or other income therefrom
                    shall be invested solely in the acquisition of shares. For
                    Members who are Canadians, shares purchased shall be voting
                    shares (ACE.B) of the company and for members who are not
                    Canadians, shares purchased shall be variable voting shares
                    (ACE.RV) of the Company.

               e)   Vesting

                    Voluntary Member contributions, along with earnings
                    thereon, vest immediately. Special Company Contributions
                    vest on March 31st of the first calendar year after the
                    initial year of contribution. Company contributions
                    representing the 33 1/3% match of Member Contributions vest
                    upon payment on April 1st following the end of any plan
                    year.

               f)   Forfeitures

                    Upon a Member withdrawal from the Plan prior to the Special
                    Company Contribution's vesting date of March 31st following
                    the end of the plan year, such member will automatically be
                    deemed to have forfeited his/her entitlement to any and all
                    unvested shares purchased by the Trustee with such member's
                    Special Company Contributions (the "Forfeited Shares"). The
                    Forfeited Shares shall be sold by the Trustee and the
                    proceeds shall revert to the Company.

               g)   Benefits

                    The vested portion of a Member's account can be withdrawn
                    from the Plan at any time. Benefits are paid in the form of
                    shares, cash equal to the net proceeds of disposition of
                    the shares credited to the Member pursuant to the Plan, or
                    a combination of both, as directed by the Member.

                    Upon involuntary termination of employment without cause,
                    death or retirement, all shares acquired with the Special
                    Company Contributions in the Member's account vest
                    automatically. The Administrative Agent shall transfer and
                    deliver the Investments held on the Member's behalf in the
                    Plan to the Member or the legal representatives of the
                    deceased Member's estate or his/her beneficiaries, as the
                    case may be.

2.       Summary of Significant Accounting Policies

               a)   Basis of accounting

                    The accompanying financial statements have been prepared on
                    the accrual basis of accounting using generally accepted
                    accounting principles in the United States.

               b)   Investment valuation

                    The ACE Aviation Holdings Inc. shares are recorded at
                    market value, which is determined by the closing price on
                    the Toronto Stock Exchange whereon the stock is principally
                    traded. For shares remaining in the Plan at year-end, the
                    difference between this amount and the average cost is
                    shown as net change in unrealized appreciation
                    (depreciation) in market value of ACE Aviation Holdings
                    Inc. shares. For shares withdrawn from the Plan during the
                    year, the difference between the market value at the date
                    the shares are withdrawn and the average cost is shown as
                    gains (losses) on ACE Aviation Holdings Inc. shares.

               c)   Investment transactions and income recognition

                    Investment transactions are accounted for on a trade date
                    basis. Dividend income is recorded on the ex-dividend date.
                    Realized gains and losses from investment transactions are
                    calculated on an average cost basis.

               d)   Administrative expenses

                    Administrative expenses of the Plan are paid directly by
                    the Company and are therefore not reflected in the
                    accompanying financial statements.

               e)   Benefit payments

                    Benefits are recorded when paid to Members.

               f)   Use of estimates

                    The preparation of financial statements in conformity with
                    accounting principles generally accepted in the United
                    States of America requires management to make certain
                    estimates and assumptions that affect the reported amounts
                    of assets at the date of the financial statements and the
                    reported amounts of income and expenses during the
                    reporting period. Actual results could differ from those
                    estimates.

3.       Investments

         As of December 31, 2005, the plan held 186,316 voting common shares
         (ACE.B) and 3,370 variable voting common shares (ACE.RV) of ACE
         Aviation Holdings Inc. The aggregate proceeds on the disposal of
         shares was $91,273 and the aggregate cost was $91,214.

4.       Plan Termination

         The Company has the right under the Plan to terminate the Plan at any
         time. In the event of termination of the Plan, the Unvested Shares
         held in the Trust Fund in trust on behalf of the Member, if any, shall
         automatically become Vested Shares and the Fair Market Value of such
         Vested Shares as of the date of the occurrence shall be credited to
         the account of the Member and the Administrative Agent shall transfer
         and deliver the Investments held on the Member's behalf in the Plan to
         the Member.

5.       Income taxes

         The Plan is an after tax defined contributions savings plan and does
         not constitute a taxpayer under the Income Tax Act (Canada). No
         provision for income taxes has therefore been included in the
         financial statements.


6.       Subsequent Event

         Special Distribution of Aeroplan Units

         On February 16, 2006, ACE Aviation Holdings Inc. announced a special
         distribution to its shareholders of units of Aeroplan Income Fund. The
         distribution of 0.18 Aeroplan unit per Class A variable voting share,
         Class B voting share, and preferred shares (on an as converted basis)
         of ACE was made as a return of capital. The record date for the
         purpose of the special distribution was March 3, 2006. The special
         distribution will be paid on or about March 31, 2006. The
         Administrative Agent will receive the special distribution in the form
         of units of Aeroplan Income Fund on behalf of Members that are not
         residents of the United States and in the form of cash on behalf of
         Members that are residents of the United States. In accordance with
         the terms of the Plan, the units of Aeroplan Income Fund received on
         behalf of Members that are not residents of the United States will be
         sold on the open market and the proceeds of such sale and the cash
         received on behalf of Members that are residents of the United States,
         will be used to acquire shares of ACE Aviation Holdings Inc. which
         will be credited to the accounts of the individual Members.
