Explanation of Responses:

(1) These shares were acquired by the reporting person under the Issuer's 2002 Stock Incentive Plan.
(2) Pursuant to the Issuer's 2002 Stock Incentive Plan, the reporting person is awarded one and one-half (1 1/2) shares of restricted Common Stock for each share of Common Stock acquired by the reporting person under the Plan.
(3) These shares are owned by a trust of which the reporting person is a trustee and a beneficiary. Except to the extent of his interest in the trust, the reporting person disclaims beneficial ownership of shares held by the trust.
(4) 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 acquired through compensati on deferral. Dividends which would have been received on shares represented by Share Units are also invested in Share Units. The Share Units are settled in cash, generally at the time the reporting person ceases to be a Director of the Issuer.
(5) These Share Units were acquired through phantom dividend reinvestment.
(6) 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.
