ITEM 5.  OTHER EVENTS.

          XL Capital Ltd, a limited liability company organized and
incorporated under the laws of the Cayman Islands ("XL"), Dasher Acquisition
Corp., a Delaware corporation and a newly-formed, direct, wholly-owned
subsidiary of XL ("Sub"), and NAC Re Corp., a Delaware corporation ("NAC
Re"), entered into an Agreement and Plan of Merger, dated as of February 15,
1999 (the "Merger Agreement"), pursuant to which Sub will merge with and into
NAC Re with NAC Re being the surviving corporation and becoming a wholly-
owned subsidiary of XL (the "Merger").  

          In accordance with the terms of the Merger Agreement, at the
effective time of the Merger (the "Effective Time") and without any action on
the part of the holders thereof, (i) each share of common stock of NAC Re,
par value $0.10 per share ("NAC Re Common Stock") issued and outstanding
immediately prior to the Effective Time will be converted into the right to
receive 0.915 of a Class A Ordinary Share, par value $0.01 per share, of XL
("XL Ordinary Shares"), together with the associated purchase rights under
the Rights Agreement, dated as of September 11, 1998, between XL and 
ChaseMellon Shareholder Services, L.L.C., with any cash to be paid in lieu of 
fractional XL Ordinary Shares.

          Consummation of the Merger is subject to a number of customary
closing conditions, including: (i) adoption of the Merger Agreement by an
affirmative vote of the holders of a majority of the outstanding shares of
NAC Re Common Stock; (ii) expiration or termination of the waiting period
under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended;
and (iii) receipt of requisite insurance and other regulatory approvals.

          In connection with the Merger Agreement, XL and NAC Re entered into
a Stock Option Agreement, dated as of February 15, 1999 (the "Stock Option
Agreement") pursuant to which XL would have the right, upon the occurrence of
certain events and subject to other specified conditions, to buy from NAC Re a
number of shares of NAC Re Common Stock equal to approximately 10% of the 
outstanding shares of NAC Re Common Stock as of February 15, 1999.

          The preceding description is qualified in its entirety by reference
to the Merger Agreement and the Stock Option Agreement, copies of which are 
included as Exhibits 99.1 and 99.2 hereto, respectively.  A copy of the joint 
press release of XL and NAC RE announcing the execution of the Merger Agreement
is filed as Exhibit 99.3 hereto and incorporated by referenced herein.
