Explanation of Responses:

*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	Holdings under the Markel Corporation 401(K) Plan are reported in units. The information reported herein is based on a plan statement dated as of December 29, 2006 and utilizes the closing stock price on that date of $480.10 per share. As of 12/29/2006, a unit under the Plan represented one share of Common Stock.
(2)	Beneficial ownership of securities is expressly disclaimed.
(3)	On February 5, 2007, Mr. Kirshner entered into a Prepaid Forward Agreement ("3-Year Forward Agreement") relating to the forward sale of 7500 shares of common stock of Markel Corporation ("Common Stock"). On February 5, 2007, the counterparty to the 3-Year Forward Agreement sold 7500 shares of Common Stock into the public market in accordance with paragraphs (f) and (g) of Rule 144 under the Securities Act of 1933, as amended, at a weighted average per-share price equal to $493.1288 (the "3-Year Floor Price"). The 3-year Forward Agreement provides that three business days after February 5, 2010 (the "3-Year Maturity Date"), Mr. Kirshner will deliver to the counterparty to the 3-Year Forward Agreement a number of shares of Common Stock (or, at the election of Mr. Kirshner, the cash equivalent of such shares) based on an agreed formula.
(4)	The agreed formula provides that (a) if the closing price per share of Common Stock on the 3-Year Maturity Date ("3-Year Final Price") is less than the 3-Year Floor Price, Mr. Kirshner will deliver 7500 shares; (b) if the 3-Year Final Price is equal to or greater than the 3-Year Floor Price but less than or equal to $641.0674 (the "3-Year Cap Price"), Mr. Kirshner will deliver a number of shares equal to the 3-Year Floor Price/3-Year Final Price x 7500; and (c) if the 3-Year Final Price is greater than the 3-Year Cap Price, Mr. Kirshner will deliver a number of shares equal to the product of the sum of [(3-Year Floor Price/3-Year Final Price) + ((3-Year Final Price - 3-Year Cap Price)/3-Year Final Price)] x 7500. In consideration of the 3-Year Forward Agreement, Mr. Kirshner received a price of $3,030,892.89.
