Item 5.   Other Information.
          ------------------

          On August 15, 1999, Markel Corporation (the "Company") and Terra Nova
(Bermuda) Holdings Ltd., a Bermuda corporation ("Terra Nova"), entered into an
Agreement and Plan of Merger and Scheme of Arrangement (the "Merger Agreement"),
providing, subject to the terms and conditions set forth therein, for (i) the
merger ("Merger") of MINT Sub Ltd., a corporation to be organized under the laws
of Virginia as a wholly-owned subsidiary of Virginia Holdings Inc. ("MINT"), a
corporation to be organized under the laws of Virginia, with and into the
Company and (ii) a Scheme of Arrangement between Terra Nova and certain of its
shareholders (the "Scheme"). Upon completion of the Merger and the Scheme, each
of the Company and Terra Nova will be a wholly-owned subsidiary of MINT, which
will be renamed Markel Corporation.

          Pursuant to the Scheme and the Merger, existing holders of Terra
Nova's common shares will receive at their election 0.184 of a share of common
stock of MINT ("MINT Shares") or $34.00 in cash for each of their shares,
subject to pro-ration to the extent the cash or stock elections exceed certain
maximum amounts specified in the Merger Agreement, and existing holders of the
common stock of the Company will receive one (1) MINT Share for each of their
shares.

          In connection with the Merger, certain shareholders of the Company and
certain shareholders of Terra Nova have entered into stockholders agreements,
dated August 15, 1999 (the "Stockholders Agreements"), with the Company and
Terra Nova, pursuant to which such shareholders have agreed to vote their stock
in favor of the Merger Agreement and the transactions contemplated thereby.

          Also on August 15, 1999, certain shareholders of Terra Nova have
entered into a registration rights agreement (the "Registration Rights
Agreement") with the Company, pursuant to which the Company has agreed to cause
MINT to grant such shareholders registration rights with respect to the MINT
Shares they will receive in the transaction.

          The consummation of the transactions contemplated by the Merger
Agreement is subject to regulatory approvals and the satisfaction or waiver of a
number of other conditions as more fully described in the Merger Agreement.


          Copies of the Merger Agreement, the Stockholders Agreements, the
Registration Rights Agreement and the related press release are attached as
exhibits hereto and are incorporated herein by reference
