filed on October 12, 2005, by Amendment No. 4 thereto filed on December 27,

Fairfax, through a subsidiary, pursuant to a master note purchase agreement,
dated as of March 3, 2003, of 4,300,000 outstanding Shares (the "2003 Purchased

with the Securities and Exchange Commission on October 7, 2005.

          Amendment No. 4 to the Schedule 13D related to the transfer (the "2005
Transfer") by TIG Insurance Company, a wholly-owned subsidiary of Fairfax, of

as follows:

          "The 2003 Purchased Shares were acquired and the 2004 Purchase, the
2005 Purchase, the 2005 Transfer and the Purchase were made by Fairfax for
investment purposes and in order for Odyssey Re Holdings Corp. ("OdysseyRe") to
be included in Fairfax's U.S. consolidated tax group so as to more quickly use
Fairfax's future income tax asset and to allow for the cash flow benefit of
receiving tax sharing payments from OdysseyRe.

          The Reporting Persons have the following plans and proposals:

          (a) The Reporting Persons currently do not intend to acquire or
dispose of Shares, but may formulate plans to do so in the future. The Reporting
Persons intend to review, on a continuous basis, various factors related to
their direct or indirect investment, as the case may be, in OdysseyRe, including
the price and availability of the Shares, subsequent developments affecting
OdysseyRe's business, other investment and business opportunities available to
the Reporting Persons and general stock market and economic conditions. Based
upon these and other factors, the Reporting Persons may decide to purchase
additional Shares or may decide in the future to sell all or part of their
investment in OdysseyRe. In addition, see the description of the Note
Cancellation Agreement (defined below) in Item 6 below, pursuant to which
Intrepid (defined below) has agreed to use commercially reasonable efforts to
purchase Shares;

          (b) The Reporting Persons have no plans or proposals to cause
OdysseyRe to enter into any extraordinary corporate transaction, such as a
merger, reorganization or liquidation of OdysseyRe or any of its subsidiaries;

          (c) The Reporting Persons have no plans or proposals to cause
OdysseyRe or any of its subsidiaries to sell or transfer a material amount of
assets;

          (d) The Reporting Persons have no plans or proposals which would
result in a change in the present board of directors or management of OdysseyRe,
whether through a change in the number or term of directors or otherwise;

          (e) The Reporting Persons have no plans to make any material change in
the present capitalization or dividend policy of OdysseyRe;

          (f) The Reporting Persons have no plans or proposals to cause
OdysseyRe to make any other material change in its business or corporate
structure;

          (g) The Reporting Persons have no plans or proposals to cause
OdysseyRe to change its certificate of incorporation or bylaws or to take other
actions which may impede the acquisition of control of OdysseyRe by any person;

          (h) The Reporting Persons have no plans or proposals to cause the
Shares to be delisted from any securities exchange or cease to be authorized to
be quoted in an inter-dealer quotation system;


                                       16



          (i) The Reporting Persons have no plans or proposals to cause the
Shares to become eligible for termination of registration pursuant to Section
12(g) of the Exchange Act; and

          (j) The Reporting Persons have no plans or proposals to take any
actions similar to those enumerated above."

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER

          Item 5 of the Schedule 13D is hereby amended in its entirety to read
as follows:

          "(a) Based on the most recent information available, the aggregate
number and percentage of the Shares (the securities identified pursuant to Item
1 of this Schedule 13D) that are beneficially owned by each of the Reporting
Persons is set forth in boxes 11 and 13 of the second part of the cover page to
this Schedule 13D for each of the Reporting Persons, and such information is
incorporated herein by reference.

          (b) The number of Shares as to which each of the Reporting Persons has
sole voting power, shared voting power, sole dispositive power and shared
dispositive power is set forth in boxes 7, 8, 9 and 10, respectively, on the
second part of the cover page to this Schedule 13D for each of the Reporting
Persons, and such information is incorporated herein by reference.

          (c) Except as described herein, none of the Reporting Persons, nor, to
the best knowledge of the Reporting Persons, any person listed in Annex A, B, C,
D, E, F, G, H, I, J, K or L beneficially owns, or during the last 60 days has
acquired or disposed of, any Shares.

          To the best knowledge of the Reporting Persons, the following persons
beneficially own approximately the following amounts of Shares and have sole
voting power and sole dispositive power with respect to such Shares, except that
Mr. Griffiths shares voting and dispositive power over 5,000 of such Shares with
Fourfourtwo Investments Limited, a company controlled by Mr. Griffiths (in each
case the amount of Shares accounts for less than 1% of the total outstanding
amount of Shares):


                   
James F. Dowd          22,881
Andrew A. Barnard     517,709
Anthony Griffiths      10,000
Brandon W. Sweitzer     4,750
Frank B. Bennett        4,050


          The Shares shown above for James F. Dowd and Andrew A. Barnard include
Shares acquired pursuant to OdysseyRe's Employee Share Purchase Plan within the
last 60 days. Mr. Barnard has reported on Form 4 the disposition on July 3, 2006
of 17,981 Shares at a price of $25.25 per share, reflecting the disposition of
restricted shares to satisfy Mr. Barnard's tax liability.

          (d) No person is known to have the right to receive or the power to
direct the receipt of dividends from, or the proceeds from the sale of, Shares
held by the Reporting Persons other than each of the Reporting Persons.


                                       17



          (e) Not applicable."

ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO
     SECURITIES OF THE ISSUER

          Item 6 of the Schedule 13D is hereby amended in its entirety to read
as follows:

          "Except as described herein, none of the Reporting Persons, nor to the
best knowledge of each of the Reporting Persons, any person listed in Annex A,
B, C, D, E, F, G, H, I, J, K or L has any contract, arrangement, understanding
or relationship (legal or otherwise) with any person with respect to any
securities of OdysseyRe, including, but not limited to, transfer or voting of
any of the securities, finder's fees, joint ventures, loan or option
arrangements, puts or calls, guarantees of profits, division of profits or loss,
or the giving or withholding of proxies other than as described below.

          Pursuant to a master note purchase agreement among Fairfax LLC, the
Purchaser, Fairfax, as guarantor, and Banc of America Securities LLC, as agent,
dated as of November 19, 2004 (the "Master Note Purchase Agreement"), in
consideration for the Old Exchangeable Notes, Fairfax LLC issued (1) $68,092,000
aggregate principal amount of New Exchangeable Notes that are exchangeable into
2,900,000 Shares at the option of the Purchaser during the period beginning on
and including November 3, 2006 through and including November 17, 2006, such
date the "Exchange Period End Date" for such Exchangeable Notes and (2)
$32,872,000 aggregate principal amount of New Exchangeable Notes exchangeable
into 1,400,000 Shares at the option of the Purchaser during the period beginning
on and including August 4, 2006 through and including August 18, 2006, such date
the "Exchange Period End Date" for such Exchangeable Notes. The Old Exchangeable
Notes have been cancelled. In addition, under the Master Note Purchase
Agreement, the New Exchangeable Notes are exchangeable at the option of the
Purchaser if at any time prior to the applicable Exchange Period End Date (a)
OdysseyRe shall declare either (i) a dividend on the Shares to be paid in
property other than cash or Shares or (ii) a quarterly cash dividend in excess
of $0.03125 per Share, or (b) Fairfax LLC fails to reimburse the Purchaser for
certain costs. The performance of Fairfax LLC's obligations under the New
Exchangeable Notes has been guaranteed by Fairfax and, pursuant to a pledge
agreement among Fairfax LLC, the Purchaser, and Banc of America Securities LLC,
as agent, dated as of November 19, 2004 (the "Pledge Agreement"), secured by a
pledge of the 2003 Purchased Shares in favor of the Purchaser. Immediately
following the 2004 Purchase, the Purchaser transferred the New Exchangeable
Notes to Intrepid Portfolios LLC ("Intrepid"), an affiliate of Bank of America,
N.A. In addition, the Purchaser transferred its rights and obligations, and
Intrepid assumed the Purchaser's rights and obligations, under the Master Note
Purchase Agreement and the Pledge Agreement.

          Pursuant to a note cancellation and purchase price adjustment
agreement, dated as of August 18, 2006, among Fairfax LLC, Fairfax, Intrepid and
Banc of America Securities LLC (the "Note Cancellation Agreement"), Fairfax LLC
purchased for cancellation from Intrepid $23,480,000 aggregate principal amount
of New Exchangeable Notes (the "Purchased Notes"). Fairfax LLC agreed to pay a
purchase price of $23,546,000 for the Purchased Notes, which purchase price is
subject to adjustment, as set forth in the Note Cancellation Agreement, to
reflect costs incurred by Intrepid and its affiliates in relation to the Note
Cancellation Agreement, including costs related


                                       18



to the purchase by Intrepid of Shares that will be used to cover all or a
portion of any hedge maintained. Pursuant to the Note Cancellation Agreement,
Intrepid has agreed to use commercially reasonable efforts to purchase 1,000,000
Shares, on any securities exchange or privately. Intrepid has agreed to use good
faith efforts to effect such purchases of Shares in a manner that would, if
Intrepid were Fairfax LLC or an affiliated purchaser of Fairfax LLC, be subject
to the safe harbor provided by Rule 10b-18(b) under the Securities Exchange Act
of 1934, as amended, or otherwise in a manner that Intrepid, in its discretion,
believes is in compliance with applicable requirements. $9,392,000 aggregate
principal amount of New Exchangeable Notes was cancelled on May 26, 2006 and, as
a result, following the purchase and cancellation of the Purchased Notes by
Fairfax LLC pursuant to the Note Cancellation Agreement, $68,092,000 aggregate
principal amount of New Exchangeable Notes remains outstanding.

          OdysseyRe has entered into a registration rights agreement with TIC
and ORH Holdings. The registration rights agreement includes rights to require
OdysseyRe to register the offer and sale of Shares held by TIC and ORH Holdings
on up to three different occasions. Each of TIC and ORH Holdings may also
require OdysseyRe to file registration statements on Form S-3. The registration
rights agreement also includes the right to require OdysseyRe to include
OdysseyRe common stock held by TIC and ORH Holdings in up to three future
registration statements that OdysseyRe files with the Securities and Exchange
Commission. Under the agreement, OdysseyRe also provides TIC and ORH Holdings
with the right to participate in any securities offerings by OdysseyRe in order
to maintain their percentage ownership. These rights are subject to various
conditions and limitations. Under the registration rights agreement, OdysseyRe
will bear all expenses incurred in connection with the registrations, other than
any underwriting discounts and commissions. Registration of Shares upon the
exercise of these registration rights would result in such Shares becoming
freely tradable without restriction under the Securities Act of 1933, as
amended.

          Messrs. Andrew A. Barnard, James F. Dowd, Frank B. Bennett, Anthony
Griffiths and Brandon W. Sweitzer have been granted stock options to purchase
Shares in the amount of 62,500, 15,000, 3,750, 5,000, 3,750, respectively, under
the OdysseyRe 2002 Stock Incentive Plan that have vested but which have not been
exercised."
