     This Form 8-A/A is filed by MGIC Investment Corporation (the "Company") to
amend and restate Item 1 of the Form 8-A filed by the Company on July 27, 1999
and to file the exhibits listed under Item 2 to reflect the adoption of certain
amendments to the Company's Rights Agreement, dated July 22, 1999, between the
Company and Wells Fargo Bank Minnesota, National Association (as successor
Rights Agent to U.S. Bank National Association).

Item 1.   Description of Registrant's Securities to be Registered.
          -------------------------------------------------------

     On July 22, 1999, the Board of Directors of MGIC Investment Corporation
(the "Company") declared a dividend of one common share purchase right (a
"Right") for each outstanding share of common stock, $1.00 par value, of the
Company (the "Common Shares"). The dividend was paid on August 9, 1999 to the
shareholders of record on that date (the "Record Date"). Each Right entitles the
registered holder to purchase from the Company one-half of one Common Share, at
a price of $225 per Common Share (equivalent to $112.50 for each one-half of a
Common Share), subject to adjustment (the "Purchase Price"). In connection
therewith, the Company entered into a Rights Agreement, dated July 22, 1999,
with U.S. Bank National Association (as successor to Firstar Bank Milwaukee,
N.A.), as Rights Agent ("U.S. Bank"). On October 24, 2002, the Board of
Directors of the Company authorized (i) the First Amendment to Rights Agreement
(the "First Amendment") and the Second Amendment to Rights Agreement (the
"Second Amendment"), with the modifications to the Rights Agreement made by such
Amendments to be effective at the time of the Board's authorization; and (ii)
Wells Fargo Bank Minnesota, National Association to become the successor Rights
Agent (the "Rights Agent"). The description and terms of the Rights are set
forth in the Rights Agreement, as amended by the First Amendment and the Second
Amendment (as so amended, the "Rights Agreement").

     Until the earlier to occur of (i) 10 days following a public announcement
that a person or group of affiliated or associated persons (other than the
Company, a subsidiary of the Company or an employee benefit plan of the Company
or a subsidiary) (an "Acquiring Person") has acquired beneficial ownership of
the Designated Percentage (as such term is defined below) or more of the
outstanding Common Shares (the "Shares Acquisition Date") or (ii) 10 business
days (or such later date as may be determined by action of the Company's Board
of Directors prior to such time as any person becomes an Acquiring Person)
following the commencement of, or announcement of an intention to make, a tender
offer or exchange offer the consummation of which would result in the beneficial
ownership by a person or group (other than the Company, a subsidiary of the
Company or an employee benefit plan of the Company or a subsidiary) of the
Designated Percentage or more of such outstanding Common Shares (the earlier of
such dates being called the "Distribution Date"), the Rights will be evidenced,
with respect to any of the Common Share certificates outstanding as of the
Record Date, by such Common Share certificate.

     The "Designated Percentage," as such term is used in the Rights Agreement,
generally means 15%; except that, in the case of an investment adviser and any
investment company advised by that investment adviser, the "Designated
Percentage" means 17.5%, for so long as certain conditions are satisfied. Those
conditions are that (i) the securities were not acquired and are not held with a
purpose or the effect of changing or influencing control of the Company, or in
connection with or as a participant in any transaction having that purpose or
effect; (ii) excluding shares beneficially owned by an investment adviser
through its affiliates (as determined pursuant to the Rights Agreement), except
that shares in the portfolio of an investment company managed by an investment
adviser are beneficially owned by the investment adviser and are not so excluded
even if the investment company is an affiliate, the aggregate amount of
securities beneficially owned by an investment adviser and by all investment
advisers the investment advisory activities of which are commonly managed are
less than 17.5% of the Common Shares of the Company then outstanding; and (iii)
including shares beneficially owned by an investment adviser and its affiliates
(as determined pursuant to the Rights Agreement), the aggregate amount of
securities beneficially owned by all affiliates of an investment adviser are
less than 20% of the Common Shares of the Company then outstanding.

                                       2



     The Rights Agreement provides that, until the Distribution Date, the Rights
will be transferred with and only with the Common Shares. Until the Distribution
Date (or earlier redemption or expiration of the Rights), new Common Share
certificates issued after the Record Date, upon transfer or new issuance of
Common Shares, will contain a notation incorporating the Rights Agreement by
reference. Until the Distribution Date (or earlier redemption or expiration of
the Rights), the surrender for transfer of any certificates for Common Shares,
outstanding as of the Record Date, even without such notation, will also
constitute the transfer of the Rights associated with the Common Shares
represented by such certificate. As soon as practicable following the
Distribution Date, separate certificates evidencing the Rights ("Right
Certificates") will be mailed to holders of record of the Common Shares as of
the close of business on the Distribution Date and such separate Right
Certificates alone will evidence the Rights.

     The Rights are not exercisable until the Distribution Date. The Rights will
expire on July 22, 2009 (the "Final Expiration Date"), unless the Rights are
earlier redeemed or exchanged by the Company, or the Rights Agreement is
amended, in each case as described below.

     The Purchase Price payable, and the number of Common Shares or other
securities or property issuable, upon exercise of the Rights are subject to
adjustment from time to time to prevent dilution (i) in the event of a stock
dividend on, or a subdivision, combination or reclassification of, the Common
Shares; (ii) upon the grant to holders of the Common Shares of certain rights or
warrants to subscribe for or purchase Common Shares at a price, or securities
convertible into Common Shares with a conversion price, less than the then
current market price of the Common Shares; or (iii) upon the distribution to
holders of the Common Shares of evidences of indebtedness or assets (excluding
regular quarterly cash dividends or dividends payable in Common Shares) or of
subscription rights or warrants (other than those referred to above).

     In the event that any person becomes an Acquiring Person (a "Flip-In
Event"), holders of Rights will thereafter generally have the right to receive
upon exercise that number of Common Shares (or, in certain circumstances cash,
property or other securities of the Company or a reduction in the Purchase
Price) having a market value of two times the then current Purchase Price.
Notwithstanding any of the foregoing, following the occurrence of a Flip-In
Event all Rights that are, or (under certain circumstances specified in the
Rights Agreement) were, or subsequently become beneficially owned by an
Acquiring Person, related persons and transferees will be null and void.

     In the event that, at any time following the Shares Acquisition Date, (i)
the Company is acquired in a merger or other business combination transaction or
(ii) 50% or more of its consolidated assets or earning power are sold (the
events described in clauses (i) and (ii) are herein referred to as "Flip-Over
Events"), proper provision will be made so that holders of Rights will (subject
to the limitations set forth in the Rights Agreement) thereafter have the right
to receive, upon the exercise thereof at the then current Purchase Price, that
number of shares of common stock of the acquiring company which at the time of
such transaction will have a market value of two times the then current Purchase
Price.

     With certain exceptions, no adjustment in the Purchase Price will be
required until cumulative adjustments require an adjustment of at least 1% in
such Purchase Price. No fractional Common Shares will be issued. In lieu of
fractional Common Shares equal to one-half of a Common


                                       3


Share or less, an adjustment in cash will be made based on the market price of
the Common Shares on the last trading day prior to the date of exercise. No
Rights may be exercised that would entitle the holder thereof to any fractional
Common Share greater than one-half of a Common Share unless concurrently
therewith such holder purchases an additional fraction of a Common Share, which
when added to the number of Common Shares to be received upon such exercise,
equals an integral number of Common Shares.

     The Purchase Price is payable by certified check, cashier's check, bank
draft or money order or, if so provided by the Company, the Purchase Price
following the occurrence of a Flip-In Event and until the first occurrence of a
Flip-Over Event may be paid in Common Shares having an equivalent value.

     At any time after a person becomes an Acquiring Person and prior to the
acquisition by any Acquiring Person of 50% or more of the outstanding Common
Shares, the Board of Directors of the Company may exchange the Rights (other
than Rights owned by any Acquiring Person which have become void), in whole or
in part, at an exchange ratio of one Common Share per Right (subject to
adjustment).

     At any time prior to a person becoming an Acquiring Person, the Board of
Directors of the Company may redeem the Rights in whole, but not in part, at a
price of $.001 per Right (the "Redemption Price"). The redemption of the Rights
may be made effective at such time, on such basis and with such conditions as
the Board of Directors in its sole discretion may establish. Immediately upon
any redemption of the Rights, the right to exercise the Rights will terminate
and the only right of the holders of Rights will be to receive the Redemption
Price.

     Other than amendments that would change the Redemption Price or move to an
earlier date the expiration of the Rights, the terms of the Rights may be
amended by the Board of Directors of the Company without the consent of the
holders of the Rights, including an amendment to lower the threshold for
exercisability of the Rights from the Designated Percentage to not less than
10%, with appropriate exceptions for any person then beneficially owning a
percentage of the number of Common Shares then outstanding equal to or in excess
of the new threshold, except that from and after the Distribution Date no such
amendment may adversely affect the interests of the holders of the Rights.

     Until a Right is exercised, the holder thereof, as such, will have no
rights as a shareholder of the Company, including, without limitation, the right
to vote or to receive dividends.

     As long as the Rights are attached to the Common Shares, the Company will
issue one Right for each Common Share which becomes outstanding between the
Record Date and the Distribution Date so that all such shares will have attached
Rights.

     The Rights have certain anti-takeover effects. The Rights will cause
substantial dilution to a person or group that attempts to acquire the Company
without conditioning the offer on redemption of the Rights or on a substantial
number of Rights being acquired. The Rights should not interfere with any merger
or other business combination approved by the Board of Directors of the Company
prior to the time that the Rights may not be redeemed (as described above) since
the Board of Directors may, at its option, at any time until the Shares
Acquisition Date redeem all but not less than all the then outstanding Rights at
$.001 per Right. The Rights are designed to provide additional protection
against abusive takeover tactics such as offers for all shares at less than full
value or at an inappropriate time (in terms of maximizing long-term shareholder
value), partial tender offers and


                                       4


selective open-market purchases. The Rights are intended to assure that the
Company's Board of Directors has the ability to protect shareholders and the
Company if efforts are made to gain control of the Company in a manner that is
not in the best interests of the Company and its shareholders.

     The Rights Agreement, the form of the First Amendment and the form of the
Second Amendment are attached hereto as exhibits. The foregoing description of
the Rights does not purport to be complete and is qualified in its entirety by
reference to such exhibits.
