ODYSSEY RE HOLDINGS CORP.
                                 (NON-QUALIFIED)
                          EMPLOYEE SHARE PURCHASE PLAN


              1. Purpose. The purpose of the Odyssey Re Holdings Corp.
(Non-Qualified) Employee Share Purchase Plan, as amended from time to time (the
"Plan"), is to provide eligible employees with an opportunity to purchase Shares
(as such term is defined below) through payroll deductions and employer
contributions. It is the intention of Odyssey Re Holdings Corp., a Delaware
corporation, and any successor thereto (the "Company") that the Plan shall not
qualify as an "Employee Stock Purchase Plan" under Section 423 of the U.S.
Internal Revenue Code of 1986, as amended (the "Code"). Participation in the
Plan will provide eligible employees who wish to acquire an interest in the
Company with a method of doing so which is both convenient and, by virtue of
employer contributions, favorable to the employees. It is believed that employee
participation in ownership of the Shares on this basis will be to the mutual
benefit of the employees and the Participating Companies (as such term is
defined below).

              2. Definitions and Rules of Construction.

behalf of each Employee who is then a Participant in an amount equal to twenty
percent (20%) of the amount of Participant Contributions made by that
Participant during the immediately preceding Plan Year.

              7. Accounts and Allocations to Participants.

              (a) The Administrator shall establish and maintain a separate
Account in respect of each Participant showing all Participant Contributions and
Company Contributions, the total number of whole Shares and fractional Shares,
and the amount of dividends (and interest thereon, if any), allocated to his

purchase on the open market in a timely manner as many Shares as may be acquired
with such contributions.

              (b) Upon any such purchase of Shares, the Custodian shall allocate
to each Participant's Account the number of whole and fractional Shares to which
such Participant is entitled. All Shares purchased pursuant to the provisions of
this Section 9 shall be subject to a Restricted Period and such Shares shall be
held by the Custodian in escrow on behalf of the applicable Participants until
the expiration of the Restricted Period.

herein.

              10. Restricted Period.

              (a) A Participant may not Transfer any Share allocated to his
Account in any Plan Year during the period commencing on the date such Share is
so allocated and expiring at the end of the Withdrawal Notice Period falling in
the immediately following Plan Year (the "Restricted Period").

              (b) Until the expiration of the Restricted Period, a Participant
shall not be entitled to delivery of a certificate evidencing a Share which is
subject to the restrictions on transferability set forth in Section 10(a).

              (c) Any cash dividends and stock dividends with respect to Shares
subject to a Restricted Period shall be subject to the same restrictions as the
underlying Shares.

              11. Distributions from the Plan.

              (a) Upon the expiration of the Restricted Period with respect to
any Share, the restrictions set forth in Section 10 shall be of no further force
or effect with respect to such Share. During the Withdrawal Notice Period in
each Year, a Participant may submit written notification to the Company that he
wishes to withdraw some or all of the whole Shares allocated to his Account, in
which event the Custodian shall, within a reasonable time after the last day of
February in such Year, deliver to the Participant, without charge, one or more
certificates evidencing the Shares requested. Any such distribution shall reduce
the number of Shares allocated to such Participant's Account.

              (b) Within a reasonable time after the last day of February in
each Plan Year, the Custodian and/or the Administrator shall distribute to each
Participant all cash dividends (and, if applicable, any interest earned thereon)
forming part of such Participant's Account at the end of the immediately
preceding Plan Year.

              (c) Within a reasonable time after the termination of a
Participant's employment with the Participating Companies for any reason, the
Custodian and/or the Administrator shall deliver to the Participant, without
charge, one or more certificates evidencing the whole Shares, and any cash
dividends or stock dividends, credited to the Participant's Account, together
with a cash payment in lieu of any fractional Shares credited to his Account, in
the amount determined by the Administrator and funded by the Company, and
together with any other assets then credited to his Account.

              (d) A Participant may apply to the Company at any time and from
time to time to receive an immediate distribution of part or all of the Shares
or other assets credited to his Account, or to otherwise reduce any Restricted
Period. The decision upon any such application shall be at the absolute
discretion of the Company, and no such decision, or any other determination
permitted on a discretionary basis hereunder to the Administrator or the
Company, shall have any precedent value. Any such distribution shall serve to
reduce that Participant's Account.

provided herein, and except for transfers by will or under the laws of descent
and distribution, no Employee shall have the right to Transfer either his right
to participate in the Plan or his interest in the Shares or other assets
credited to his Account, and no such attempted Transfer shall be effective.

              14. Amendment; Termination. Notwithstanding anything herein to the
contrary, the Board may, at any time, amend, modify, terminate or suspend the
Plan; provided, however, that no amendment or modification that otherwise must
be approved by stockholders, pursuant to applicable rules of a stock exchange or
any requirements under Section 162(m) of the Code and the regulations
promulgated thereunder, shall be effective without stockholder approval.
However, except as otherwise expressly provided herein, no such action will,
without the express written consent of a Participant, alter or impair his rights
existing at such time with respect to any Shares or other assets credited to his
Account.

              15. Termination of Plan. Upon termination of the Plan, all assets
credited to all Accounts shall, within a reasonable time after such termination,

accordance with the laws of the State of Delaware (without giving effect to
principles of conflicts of laws).

              19. Effective Date. The Plan shall become effective on the
Effective Date, and shall remain in effect until it has been terminated pursuant
to Section 15.

              20. Wage and Tax Withholding. The Participating Companies are
authorized to withhold from any Shares or any compensation or other payment to a
Participant amounts of withholding and other taxes due in connection with any
Shares or with any Company Contributions, and to take such other action as the
Administrator may deem necessary or advisable to enable the Company and the
Participants to satisfy obligations for the payment of withholding taxes and
other tax obligations relating thereto. This authority shall include authority
for the Company to withhold or receive Shares or other property and to make cash
