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) The reporting person participates in the MGIC Investment Corporation Deferred Compensation Plan for Non-Employee Directors under which units corresponding to shares of Common Stock of the Issuer ("Share Units") are awarded to the reporting person. The Share Units are settled in cash, generally at the time the reporting person ceases to be a Director of the Issuer, unless a qualified election for earlier distribution is made by the reporting person.
(2) These Share Units do not have a specified dollar-denominated exercise or conversion price. (Their value is based, on a one-for-one basis, on the price of the Issuer's common stock on the New York Stock Exchange.)
(3) These Share Units are subject to certain restrictions, and vest when such restrictions lapse. The restrictions generally lapse one year after the Share Units were awarded.
(4) These Share Units do not expire on a fixed date. Under certain circumstances, the Share Units are subject to forfeiture if the reporting person ceases to be a Director of the issuer before the lapse of restrictions on the Share Units.
(5) The number of Share Units beneficially owned by the reporting person includes Share Units owned prior to August 15, 1996, which were and continue to be exempt from Section 16 of the Securities and Exchange Act of 1934. The reporting person disclaims any waiver of such exemption.
