to read as follows:

                  Except as described in this Schedule 13D, none of the persons

                  In connection with the Transaction, each of Fairfax and
Odyssey Re has entered into a lock-up agreement dated March 20, 2003 and March
18, 2003, respectively (together, the "Lock-up Agreements"). The Lock-up
Agreements restrict the ability of Fairfax, OdysseyRe, and entities under the
control of either of them to directly or indirectly (without the prior written
consent of Banc of America Securities LLC, Merrill Lynch & Co. and Merrill
Lynch, Pierce, Fenner & Smith Incorporated) transfer shares of, or securities
convertible into shares of, Common Stock of Zenith for the period commencing on
the date of the agreement and ending 90 days following March 18, 2003; provided,
however, that transfers of shares of Common Stock of Zenith may be made to
entities wholly-owned by Fairfax or OdysseyRe.

                  Further, Fairfax has entered into a Proxy Agreement dated
March 28, 2002 (the "Proxy Agreement") appointing John Clark (the "Trustee") as
its proxy with respect to all matters for which Fairfax and all of its
subsidiary corporations have the right to vote shares of Common Stock of Zenith.
Under the Proxy Agreement, the Trustee shall vote such shares in the same
proportion as the vote ultimately cast by all other voting shareholders. In the
event that a proxy contest not supported by management occurs while the
Standstill Agreement remains in effect, the Trustee shall vote as recommended by
management of Zenith.

                  Fairfax has also agreed to the Standstill Amendment which
extends Fairfax's covenants and agreements contained in the Original Standstill
Agreement until the earlier of (i) December 31, 2006 or (ii) the date on which
Stanley R. Zax is no longer the full-time President and Chairman of the Board of
Directors of Zenith.

                  The descriptions in this Item 6 of the Lock-up Agreements, the
Proxy Agreement, the Standstill Amendment and the Original Standstill Agreement
are qualified in their entirety by reference to the Lock-up Agreements, the
Proxy Agreement, the Standstill Amendment and the Original Standstill Agreement,
