Dear Tom:

Reference is made to our recent conversations concerning your departure as
President and Chief Executive Officer and as a director of Magna Entertainment
Corp. ("MEC") and our agreements, which are as follows:

1.Effective March 31, 2006 (the "Officer Resignation Date"), you will resign as
President and Chief Executive Officer and as a director of MEC and as an officer
and/or director of all subsidiaries of MEC or its affiliates for which you serve
in such capacities.

2.Following the Officer Resignation Date, you will remain as an employee of MEC
for a two-month transition period. Effective May 31, 2006 (the "Employee
Resignation Date"), you will resign as an employee of MEC. You agree that on the
Employee Resignation Date you shall execute and deliver the release in the form
of Schedule A attached hereto.

3.You shall be entitled to receive your Base Salary of US$300,000 and Guaranteed
Bonus of US$200,000 annually up to and including the Employee Resignation Date.
You acknowledge that you have received such Guaranteed Bonus up to and including
December 31, 2005 so that you are only entitled to such Guaranteed Bonus for the
period from January 1, 2006 to March 31, 2006 (the "2006 First Quarter Bonus")
and for the period from April 1, 2006 to May 31, 2006 (the "2006 Second Quarter
Partial Bonus"). Notwithstanding the terms of your employment agreement dated
March 22, 2005 (your "Employment Agreement"), you shall receive prompt payment
of the full amount of the 2006 First Quarter Bonus and the 2006 Second Quarter
Partial Bonus, respectively, in cash from MEC at the same time that senior
executives of MEC are paid their bonuses for the first quarter of 2006 and
second quarter of 2006, respectively.

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

4.The amount of 13,086 shares (your "Incentive Stock") of MEC Class A
Subordinate Voting Stock ("Class A Stock"), being the amount of your Guaranteed
Bonus that is payable to you in Class A Stock during 2005, shall vest and be
released to you on December 1, 2006.

5.Notwithstanding the terms of your incentive stock option agreements with MEC
dated March 7, 2005 and March 21, 2005, your options to purchase 300,000 shares
of Class A Stock (your "Options") shall remain in full force and effect, shall
vest on their current schedule, and shall be exercisable at any time up to and
including the Expiration Date (as defined in your stock option agreements) and
without application of the terms of sections 2.2(b) through (f) of those
agreements. However, in the event that you become employed by, a director of, or
a consultant to, any entity that competes, directly or indirectly, with MEC or
any of its subsidiaries prior to the vesting of any Options, such non-vested
Options will be cancelled (all vested Options will be unaffected and remain
in-force as set-out above).

6.You agree that you shall not sell, transfer or otherwise dispose of or trade
any securities of MEC (including, without limitation, your Incentive Stock and
your Options) before December 1, 2006. Without limiting the foregoing, you
acknowledge that it is your responsibility to be familiar with and comply with
your obligations under insider trading laws and similar securities laws.

7.Upon you having delivered on the Employee Resignation Date the executed
release as provided in paragraph 2 above, MEC shall promptly pay to you a
retiring allowance of US$500,000 as full and final settlement of all amounts
owing to you by MEC or its affiliates as a result of your employment with MEC
and its subsidiaries, including all amounts owing to you under your employment
agreement with MEC (subject only to paragraph 8 below), which amount shall be
paid to you in a lump sum (net of all usual deductions).

8.As soon as reasonably practicable following the Employee Resignation Date, you
shall submit a final expense report or reports for all outstanding expenses
which you have incurred on behalf of MEC or any of its subsidiaries in
accordance with typical practice and which have not previously been reimbursed.
All such expenses shall be reimbursed to you by MEC promptly following receipt
of such expense report(s). In addition, promptly following execution of this
agreement and submission of supporting invoices, MEC shall pay to you the amount
of up to CDN$10,000 as partial reimbursement for your legal expenses in
connection with your departure from MEC.

9.MEC shall continue to maintain on your behalf your current benefits (excluding
life and disability coverage) for a period of twelve (12) months commencing on
the Employee Resignation Date. Your current life and disability coverage shall
be maintained for a period of not less than the period required by applicable
statute.

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

10.MEC's obligations to indemnify you pursuant to its by-laws shall continue in
effect in respect of all your activities as a director, officer and employee of
MEC and its subsidiaries, and MEC shall continue to cover you under its
directors' and officers' insurance policies in respect of your service as an
officer or director of MEC and its subsidiaries (including, without limitation,
with respect to any claims made against you or losses or expenses incurred by
you in connection with the litigation brought by Greenlight Capital, Inc.
against MI Developments Inc. ("MID")). For greater certainty, MEC acknowledges
that you shall be entitled to reimbursement for all reasonable counsel fees and
disbursements in connection with your representation by counsel of your choice
(subject to approval by MEC, acting reasonably) as a witness, party or potential
witness or party in any shareholder litigation involving MEC or MID.

11.You acknowledge and agree that you are still subject to, and shall abide by,
your obligations as set forth in paragraph 8 of your Employment Agreement.

12.You agree to promptly execute and provide to MEC all documents reasonably
requested by MEC and its affiliates to evidence your resignation as a director
and/or officer of MEC and its affiliates.

13.Except as already agreed, and except as required by any applicable law,
regulation or stock exchange rule, neither you nor MEC shall make any public
announcement or issue any press release with respect to your resignation as a
director and officer of, and your departure from, MEC without the prior written
consent of the other. Prior to either party making any public announcement or
press release, such party shall provide the other party with a reasonable
opportunity to comment on said public announcement or press release.

14.Upon you having delivered on the Employee Resignation Date the executed
release as provided in paragraph 2 above, MEC shall enter into a consulting
agreement with you substantially in the form attached hereto as Schedule B. You
shall be entitled to retain the laptop computer and blackberry communications
device that you are presently using for so long as you are acting as a
consultant to MEC, although you shall arrange and pay for your own service
provider contract for your blackberry communications device.

15.You hereby acknowledge and agree that this letter agreement, including
without limitation Schedule A, supersedes all previous agreements between you
and MEC and its affiliates, whether oral or written, including without
limitation your employment agreement.

Dear Tom:

Consulting Agreement with Magna Entertainment Corp. ("MEC")

Further to our discussions, MEC wishes to retain you (the "Consultant") to
provide consulting services to assist MEC and certain of its affiliates with
various projects from time to time as determined by MEC, including without
limitation projects relating to MEC's recapitalization plan (collectively, the
"Projects"). The general terms and conditions of the consulting arrangement
would be as follows:

1.Consultant.    The Consultant shall make himself reasonably available to MEC
to carry out his obligations under this agreement. The Consultant acknowledges
that due to the nature of the Projects, the Consultant may be expected to engage
in extensive business travel.

2.Fees.    MEC shall pay the Consultant at the rate of US$2,500 per day or part
thereof (it being understood that the number of hours per month and per week may
vary from month-to-month and from week-to-week as determined by MEC). Invoices
should be rendered on a monthly basis in arrears and include GST and provincial
taxes where applicable.

3.Expenses.    MEC shall reimburse the Consultant for all reasonable business
expenses actually and properly incurred in carrying out the Projects to the
extent specifically required by MEC under this agreement and in accordance with

Canada on MEC business, it shall be the Consultant's responsibility to maintain
adequate medical coverage. The Consultant shall supply original vouchers and
receipts to support all expenses, shall itemize such expenses on a standard MEC
expense report, and shall obtain advance approval from MEC's Project Coordinator
for any individual expense in excess of CDN$5,000. The Consultant shall be based
in his own off-site office and shall be responsible for the expense of all
office costs, support services and materials in carrying out his obligations
under this agreement.

needed to complete the Project with the assistance and under the direction of
the Project Coordinator or his designees. The Consultant shall provide those

In addition, this agreement may be immediately terminated by MEC in the event
Consultant is in material breach of the provisions of this agreement.

6.Independent Contractor.    The Consultant is an independent contractor and in
no way shall the Consultant be considered an employee, agent or joint venturer
of MEC. Subject to coordination with the persons designated in paragraph 4, the
Consultant shall determine how, where and when he shall carry out his consulting
services and other obligations under this agreement. The Consultant shall have
no authority to represent or bind MEC in any way and agrees that he shall not
hold himself out as having authority to act for MEC or its affiliates.

the foregoing.

Agreement if requested by MEC.

damages arising from the Consultant's failure to comply in all material respects
with the provisions of paragraphs 6, 7, 8, 9 and 10 of this agreement.
