W I T N E S S E T H:

     WHEREAS, the Boards of Directors of Radian and MGIC have determined that it is in the best interests of their respective companies and their stockholders to consummate the strategic business combination transaction provided for herein, pursuant to which Radian will, subject to the terms and conditions set forth herein, merge with and into MGIC (the “Merger”), so that MGIC is the surviving corporation (hereinafter sometimes referred to in such capacity as the “Surviving Corporation”) in the Merger; and

     WHEREAS, for Federal income tax purposes, it is intended that the Merger shall qualify as a reorganization under Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”), and this Agreement is intended to be and is adopted as a plan of reorganization for purposes of Sections 354 and 361 of the Code; and

     WHEREAS, the parties desire to make certain representations, warranties and agreements in connection with the Merger and also to prescribe certain conditions to the Merger.

     NOW, THEREFORE, in consideration of the mutual covenants, representations, warranties and agreements contained herein, and intending to be legally bound hereby, the parties agree as follows:

MGIC shall be the Surviving Corporation in the Merger, and shall continue its corporate existence under the laws of the State of Wisconsin. Upon consummation of the Merger, the separate corporate existence of Radian shall terminate.

     (b) The parties may at any time change the method of effecting the combination of Radian and MGIC (including by providing for the merger of a wholly owned subsidiary of MGIC with and into Radian, the merger of a wholly owned subsidiary of Radian with and into MGIC or the merger of MGIC with and into Radian) if and to the extent that Radian and MGIC deem such change to be desirable; provided, however, that no such change shall (i) alter or change the amount or kind of consideration to be issued to holders of the capital stock of Radian as provided for in this Agreement (the “Merger Consideration”), except for appropriate adjustments in the event of a merger described in the preceding parenthetical (which shall in no event result in a change in the relative interests in the Surviving Corporation of the

-1-

Certificates previously representing shares of Radian Common Stock shall be exchanged for certificates representing whole shares of MGIC Common Stock and cash in lieu of fractional shares issued in consideration therefor upon the surrender of such Certificates in accordance with Section 2.2, without any interest thereon.

ARTICLE II

EXCHANGE OF SHARES

     2.1 MGIC to Make Shares Available. At or prior to the Effective Time, MGIC shall deposit, or shall cause to be deposited, with a bank or trust company reasonably acceptable to each of Radian and MGIC (the “Exchange Agent”), for the benefit of the holders of Certificates, for exchange in accordance with this Article II, certificates representing the shares of MGIC Common Stock, and cash in lieu of any fractional shares (such cash and certificates for shares of MGIC Common Stock, together with any dividends or distributions with respect thereto, being hereinafter referred to as the “Exchange Fund”), to be issued pursuant to Section 1.4 and paid pursuant to Section 2.2(a) in exchange for outstanding shares of Radian Common Stock.

     2.2 Exchange of Shares. (a) As soon as practicable after the Effective Time, and in no event later than five business days thereafter, the Exchange Agent shall mail to each holder of record of one or more Certificates a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent) and instructions for use in effecting the surrender of the Certificates in exchange for certificates representing the shares of MGIC Common Stock and any cash in lieu of fractional shares into which the shares of Radian Common Stock represented by such Certificate or Certificates shall have been converted pursuant to this Agreement. Upon proper surrender of a Certificate or Certificates for exchange and cancellation to the Exchange Agent, together with such properly completed letter of

-5-

---

transmittal, duly executed, the holder of such Certificate or Certificates shall be entitled to receive in exchange therefor, as applicable, (i) a certificate representing that number of whole shares of MGIC Common Stock to which such holder of Radian Common Stock shall have become entitled pursuant to the provisions of Article I and (ii) a check representing the amount of any cash in lieu of fractional shares which such holder has the right to receive in respect of the Certificate or Certificates surrendered pursuant to the provisions of this Article II, and the Certificate or Certificates so surrendered shall forthwith be cancelled. No interest will be paid or accrued on any cash in lieu of fractional shares payable to holders of Certificates.

     (b) No dividends or other distributions declared with respect to MGIC Common Stock shall be paid to the holder of any unsurrendered Certificate until the holder thereof shall surrender such Certificate in accordance with this Article II. After the surrender of a Certificate in accordance with this Article II, the record holder thereof shall be entitled to receive any such dividends or other distributions, without any interest thereon, which theretofore had become payable with respect to shares of MGIC Common Stock represented by such Certificate.

     (c) If any certificate representing shares of MGIC Common Stock is to be issued in a name other than that in which the Certificate or Certificates surrendered in exchange therefor is or are registered, it shall be a condition of the issuance thereof that the Certificate or Certificates so surrendered shall be properly endorsed (or accompanied by an appropriate instrument of transfer) and otherwise in proper form for transfer, and that the person requesting such exchange shall pay to the Exchange Agent in advance any transfer or other similar Taxes required by reason of the issuance of a certificate representing shares of MGIC Common Stock in any name other than that of the registered holder of the Certificate or Certificates surrendered, or required for any other reason, or shall establish to the reasonable satisfaction of the Exchange Agent that such Tax has been paid or is not payable.

     (d) After the Effective Time, there shall be no transfers on the stock transfer books of Radian of the shares of Radian Capital Stock that were issued and outstanding immediately prior to the Effective Time. If, after the Effective Time, certificates representing such shares are presented for transfer to the Exchange Agent, they shall be cancelled and exchanged for certificates representing shares of MGIC Common Stock as provided in this Article II.

     (e) Notwithstanding anything to the contrary contained herein, no certificates or scrip representing fractional shares of MGIC Common Stock shall be issued upon the surrender for exchange of Certificates, no dividend or distribution with respect to MGIC Common Stock shall be payable on or with respect to any fractional share, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a stockholder of MGIC. In lieu of the issuance of any such fractional share, MGIC shall pay to each former stockholder of Radian who otherwise would be entitled to receive such fractional share an amount in cash determined by multiplying (i) the average of the closing-sale prices of MGIC Common Stock on the New York Stock Exchange, Inc. (the “NYSE”) as reported by The Wall Street Journal for the five full trading days ending on the day preceding the Closing Date by (ii) the fraction of a share (rounded to the nearest thousandth when expressed in decimal form) of

-6-

---

MGIC Common Stock to which such holder would otherwise be entitled to receive pursuant to Section 1.4.

     (f) Any portion of the Exchange Fund that remains unclaimed by the stockholders of Radian for 12 months after the Effective Time shall be paid to MGIC. Any former stockholders of Radian who have not theretofore complied with this Article II shall thereafter look only to MGIC for payment of the shares of MGIC Common Stock, cash in lieu of any fractional shares and any unpaid dividends and distributions on the MGIC Common Stock deliverable in respect of each former share of Radian Common Stock such stockholder holds as determined pursuant to this Agreement, in each case, without any interest thereon. Notwithstanding the foregoing, none of MGIC, Radian, the Exchange Agent or any other person shall be liable to any former holder of shares of Radian Common Stock for any amount delivered in good faith to a public official pursuant to applicable abandoned property, escheat or similar laws.

     (g) MGIC shall be entitled to deduct and withhold, or cause the Exchange Agent to deduct and withhold, from the consideration otherwise payable pursuant to this Agreement to any holder of Radian Common Stock such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code or any provision of state, local or foreign Tax law. To the extent that amounts are so withheld by MGIC or the Exchange Agent, as the case may be, and paid over to the appropriate governmental authority, the withheld amounts shall be treated for all purposes of this Agreement as having been paid to holder of Radian Common Stock in respect of which the deduction and withholding was made by the MGIC or the Exchange Agent, as the case may be.

     (h) In the event any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if reasonably required by MGIC, the posting by such person of a bond in such amount as MGIC may determine is reasonably necessary as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the shares of MGIC Common Stock and any cash in lieu of fractional shares deliverable in respect thereof pursuant to this Agreement.

ARTICLE III

REPRESENTATIONS AND WARRANTIES OF RADIAN

Radian has the corporate power and authority to own or lease all of its properties and assets and to carry on its business as it is now being conducted, and is duly licensed or qualified to do business in each jurisdiction in which the nature of the business conducted by it or the character or location of the properties and assets owned or leased by it makes such licensing or qualification necessary,

-7-

except where the failure to be so licensed or qualified would not, either individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on Radian. As used in this Agreement, the term “Material Adverse Effect” means, with respect to MGIC, Radian or the Surviving Corporation, as the case may be, a material adverse effect on (i) the business, results of operations or financial condition of such party and its Subsidiaries taken as a whole (provided, however, that, with respect to this clause (i), Material Adverse Effect shall not be deemed to include effects resulting from (A) changes, after the date hereof, in U.S. generally accepted accounting principles (“GAAP”), (B) changes, after the date hereof, in laws, rules or regulations of general applicability or interpretations thereof by courts or Governmental Entities, (C) changes, after the date hereof, in global, national or regional political conditions (including the outbreak of war or acts of terrorism) or in economic or market conditions affecting mortgage insurance companies generally, except to the extent that any such changes have a materially disproportionate adverse effect on such party, or (D) public disclosure of the transactions contemplated hereby or actions expressly permitted or required by this Agreement or that are taken with the prior written consent of the other party in contemplation of the transactions contemplated hereby) or (ii) the ability of such party to timely consummate the transactions contemplated hereby. As used in this Agreement, the word “Subsidiary” when used with respect to any party, means any corporation, partnership, limited liability company, or other organization, whether incorporated or unincorporated, which is consolidated with such party for financial reporting purposes. True and complete copies of the Amended and Restated Certificate of Incorporation of Radian (the “Radian Certificate”) and the Bylaws of Radian, as in effect as of the date of this Agreement, have previously been made available by Radian to MGIC.

     (b) Each Radian Subsidiary (i) is duly organized and validly existing under the laws of its jurisdiction of organization, (ii) is duly qualified to do business and, where such concept is recognized under applicable law, in good standing in all jurisdictions (whether federal, state, local or foreign) where its ownership or leasing of property or the conduct of its business requires it to be so qualified and in which the failure to be so qualified would reasonably be expected to have a Material Adverse Effect on Radian and (iii) has all requisite corporate power and authority to own or lease its properties and assets and to carry on its business as now conducted.

     3.2 Capitalization. (a) The authorized capital stock of Radian consists of (i) 200,000,000 shares of Radian Common Stock, of which, as of February 5, 2007, 79,507,270 shares were issued and outstanding and 18,123,474 shares were held in treasury, and (ii) 20,000,000 shares of preferred stock, par value $0.001 per share (the “Radian Preferred Stock” and together with the Radian Common Stock, the “Radian Capital Stock”), of which no shares are issued or outstanding. All of the issued and outstanding shares of Radian Common Stock have been duly authorized and validly issued and are fully paid, nonassessable and free of preemptive rights, with no personal liability attaching to the ownership thereof. Except pursuant to the terms of options, Phantom Shares and Performance Shares issued (or to be issued in accordance with Section 5.2(b)) pursuant to the Radian Stock Plans, Radian does not have and is not bound by any outstanding subscriptions, options, warrants, calls, commitments or agreements of any character calling for the purchase or issuance of any shares of Radian Capital Stock or any other equity securities of Radian or any securities representing the right to purchase or otherwise receive any shares of Radian Capital Stock (collectively, the “Radian Rights”). As of February 5, 2007, no shares of Radian Capital Stock were reserved for issuance, except for 278,944 shares

-8-

of Radian Common Stock reserved for issuance in connection with the Radian ESPP and 6,330,807 shares of Radian Common Stock reserved for issuance upon the exercise of stock options pursuant to the Radian Stock Plans and the settlement of Performance Shares and Phantom Shares. Since February 5, 2007, Radian has not issued any shares of Radian Capital Stock or any Radian Rights, other than as permitted by Section 5.2(b) in the case of grants made following the date of this Agreement and pursuant to the exercise of employee stock options granted prior to such date. Radian has previously provided MGIC with a list of the aggregate number of options outstanding under the Radian Stock Plans as of February 5, 2007 and the weighted average exercise price for such options.

     (b) Radian owns, directly or indirectly, all of the issued and outstanding shares of capital stock or other equity ownership interests of each of the Radian Subsidiaries, free and clear of any liens, pledges, charges, encumbrances and security interests whatsoever (“Liens”), and all of such shares or equity ownership interests are duly authorized and validly issued and are fully paid, nonassessable and free of preemptive rights, with no personal liability attaching to the ownership thereof. No Radian Subsidiary has or is bound by any outstanding subscriptions, options, warrants, calls, commitments or agreements of any character calling for the purchase or issuance of any shares of capital stock or any other equity security of such Subsidiary or any securities representing the right to purchase or otherwise receive any shares of capital stock or any other equity security of such Subsidiary. Section 3.2(b) of the Radian Disclosure Schedule sets forth a list of the material investments of Radian in corporations, joint ventures, partnerships, limited liability companies and other entities other than its Subsidiaries (each a “Non-Subsidiary Affiliate”).

This Agreement has been duly and validly executed and delivered by Radian and (assuming due authorization, execution and delivery by MGIC) constitutes a valid and binding obligation of Radian, enforceable against Radian in accordance with its terms.

MGIC has the corporate power and authority to own or lease all of its properties and assets and to carry on its business as it is now being conducted, and is duly licensed or qualified to do business in each jurisdiction in which the nature of the business conducted by it or the character or location of the properties and assets owned or leased by it makes such licensing or qualification necessary, except where the failure to be so licensed or qualified would not, either individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on MGIC. True and complete copies of the MGIC Articles and Bylaws of MGIC, as in effect as of the date of this Agreement, have previously been made available by MGIC to Radian.

     (b) Each MGIC Subsidiary (i) is duly organized and validly existing under the laws of its jurisdiction of organization, (ii) is duly qualified to do business and, where such concept is recognized under applicable law, in good standing in all jurisdictions (whether Federal, state, local or foreign) where its ownership or leasing of property or the conduct of its business requires it to be so qualified and in which the failure to be so qualified would reasonably be expected to have a Material Adverse Effect on MGIC, and (iii) has all requisite corporate power and authority to own or lease its properties and assets and to carry on its business as now conducted.

The books and records of MGIC and its Subsidiaries have been, and are being, maintained in all material respects in accordance with GAAP and any other applicable legal and accounting requirements and reflect only actual transactions. PricewaterhouseCoopers LLP has not resigned or been dismissed as independent public accountants of MGIC as a result of or in connection with any disagreements with MGIC on a matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure.

     (b) Except as would not reasonably be expected to have, either individually or in the aggregate, a Material Adverse Effect on MGIC, neither MGIC nor any of its Subsidiaries has any liability of any nature whatsoever (whether absolute, accrued, contingent or otherwise and whether due or to become due), except for those liabilities that are reflected or reserved against on the consolidated balance sheet of MGIC included in its Quarterly Report on Form 10-Q for the fiscal quarter ended September 30, 2006 (including any notes thereto) and for liabilities incurred in the ordinary course of business consistent with past practice since September 30, 2006 that are reflected in the financial statements included in MGIC’s Current Report on Form 8-K filed on January 18, 2007, or incurred in the ordinary course of business consistent with past practice since December 31, 2006 or in connection with this Agreement and the transactions contemplated hereby.

MGIC (x) has implemented and maintains disclosure controls and procedures (as defined in Rule 13a-15(e) of the Exchange Act) to ensure that material information relating to MGIC, including its consolidated Subsidiaries, is made known to the chief executive officer and the chief financial officer of MGIC by others within those entities, and (y) has disclosed, based on its most recent evaluation prior to the date hereof, to MGIC’s outside auditors and the audit committee of MGIC’s Board of Directors (i) any significant deficiencies and material weaknesses in the design or operation of internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) which are reasonably likely to adversely affect MGIC’s ability to record, process, summarize and report financial information, and (ii) any fraud, whether or not material, that involves management or other employees who have a significant role in MGIC’s internal controls over financial reporting.

     (d) MGIC and Radian shall promptly advise each other upon receiving any communication from any Governmental Entity whose consent or approval is required for consummation of the transactions contemplated by this Agreement that causes such party to believe that there is a reasonable likelihood that any Requisite Regulatory Approval will not be obtained or that the receipt of any such approval will be materially delayed.

     6.2 Access to Information.

     (c) The Surviving Corporation agrees to honor in accordance with their terms all benefits vested as of the date hereof under the MGIC Benefit Plans or the Radian Benefit Plans or under other contracts, arrangements, commitments, or understandings described in the MGIC Disclosure Schedule and the Radian Disclosure Schedule.

     (d) Nothing in this Section 6.6 shall be interpreted as preventing the Surviving Corporation from amending, modifying or terminating any MGIC Benefit Plans, Radian Benefit Plans, or other contracts, arrangements, commitments or understandings, in accordance with their terms and applicable law. Without limiting the generality of the final sentence of Section 9.10, nothing in this Section 6.6, express or implied, is intended to or shall confer upon any other person including without limitation any employee of MGIC or Radian, any right, benefit or

-39-

remedy of any nature whatsoever under or by reason of this Agreement and no provision of this Section 6.6 shall constitute an amendment of any benefit plan of MGIC or Radian.

     6.7 Indemnification; Directors’ and Officers’ Insurance. (a) In the event of any threatened or actual claim, action, suit, proceeding or investigation, whether civil, criminal or administrative, including, without limitation, any such claim, action, suit, proceeding or investigation in which any individual who is now, or has been at any time prior to the date of this Agreement, or who becomes prior to the Effective Time, a director or officer or employee of Radian or any of its Subsidiaries, including any entity specified in the Radian Disclosure Schedule (the “Radian Indemnified Parties”), is, or is threatened to be, made a party based in whole or in part on, or arising in whole or in part out of, or pertaining to (i) the fact that he is or was a director, officer or employee of Radian or any of its Subsidiaries or (ii) this Agreement or any of the transactions contemplated hereby, whether in any case asserted or arising before or after the Effective Time, the parties hereto agree to cooperate, and the parties shall use their reasonable best efforts to defend against and respond thereto, except that prior to the Effective Time, the foregoing obligation of MGIC with respect to the directors, officers or employees of Radian shall be only to cooperate. In the event of any threatened or actual claim, action, suit, proceeding or investigation, whether civil, criminal or administrative, including, without limitation, any such claim, action, suit, proceeding or investigation in which any individual who is now, or has been at any time prior to the date of this Agreement, or who becomes prior to the Effective Time, a director or officer or employee of MGIC or any of its Subsidiaries, including any entity specified in the MGIC Disclosure Schedule (the “MGIC Indemnified Parties”), is, or is threatened to be, made a party based in whole or in part on, or arising in whole or in part out of, or pertaining to (i) the fact that he is or was a director, officer or employee of MGIC or any of its Subsidiaries or (ii) this Agreement or any of the transactions contemplated hereby, whether in any case asserted or arising before or after the Effective Time, the parties hereto agree to cooperate, and the parties shall use their reasonable best efforts to defend against and respond thereto, except that prior to the Effective Time, the foregoing obligation of Radian with respect to the directors, officers or employees of MGIC shall be only to cooperate. It is understood and agreed that after the Effective Time, the Surviving Corporation shall indemnify and hold harmless, as and to the fullest extent permitted by law, each such Radian Indemnified Party and MGIC Indemnified Party against any losses, claims, damages, liabilities, costs, expenses (including reasonable attorney’s fees and expenses in advance of the final disposition of any claim, suit, proceeding or investigation to each Indemnified Party to the fullest extent permitted by law upon receipt of any undertaking required by applicable law), judgments, fines and amounts paid in settlement (to the extent, in the case of settlements, that the settlement was approved in writing by MGIC, such approval not to be unreasonably withheld) in connection with any such threatened or actual claim, action, suit, proceeding or investigation. It is understood that after the Effective Time the Surviving Corporation may assume and control the defense of any claim for which the Surviving Corporation is obligated to provide indemnification under this Section 6.7(a), provided that the foregoing shall not apply with respect to any claim for which counsel has been retained with the approval of the applicable liability insurer (if such approval is required under the applicable insurance policy, if any, to obtain coverage) and commenced the defense prior to the Effective Time unless the Surviving Corporation’s Audit Committee otherwise determines following the Effective Time.

     (b) Prior to the Effective Time, Radian shall use commercially reasonable efforts to convert its directors’ and officers’ liability insurance policy in effect immediately prior to the Effective Time (the “Existing Policy”) to a policy that covers the insureds thereunder only for acts or omissions occurring prior to the Effective Time (the “Runoff Policy”). The Surviving Corporation shall use its reasonable best efforts to maintain the Runoff Policy, if any, or, if no such policy has been obtained, to maintain the Existing Policy, for the benefit of such insureds, for a period of six (6) years from the Effective Time (or the period of the applicable statute of limitations, if longer) (provided that if despite such efforts neither of such policies can be maintained, the Surviving Corporation may substitute therefor policies (i) having at least the same aggregate limits and with terms of coverage that in the Surviving Corporation’s best judgment are as favorable to the insureds as may be obtained from the market for directors’ and officers’ liability insurance at the time taking into account the necessity to maintain coverage on an uninterrupted basis, or (ii) if such limits cannot be maintained, having the highest limits that may be obtained from such market taking into account such necessity). Effective at the Effective Time, coverage under the policies of directors’ and officers’ liability insurance that are maintained by the Surviving Corporation from time to time in its discretion shall not discriminate between MGIC Directors and Radian Directors (as such terms are hereinafter defined) or between persons who formerly were MGIC Directors or were Radian Directors.

     (c) The provisions of this Section 6.7 shall survive the Effective Time and are intended to be for the benefit of, and shall be enforceable by, each Indemnified Party and his or her heirs and representatives.

     6.8 Additional Agreements. In case at any time after the Effective Time any further action is necessary or desirable to carry out the purposes of this Agreement (including, without limitation, any merger between a Subsidiary of MGIC, on the one hand, and a Subsidiary of Radian, on the other) or to vest the Surviving Corporation with full title to all properties, assets, rights, approvals, immunities and franchises of any of the parties to the Merger, the proper officers and directors of each party to this Agreement and their respective Subsidiaries shall take all such necessary action as may be reasonably requested by, and at the sole expense of, MGIC.

     6.9 Advice of Changes. MGIC and Radian shall each promptly advise the other party of any change or event (i) having a Material Adverse Effect on it or (ii) which it believes would or would be reasonably likely to cause or constitute a material breach of any of its representations, warranties or covenants contained herein; provided that any failure to give notice in accordance with the foregoing with respect to any breach shall not be deemed to constitute a violation of this Section 6.9 or the failure of any condition set forth in Section 7.2 or 7.3 to be satisfied, or otherwise constitute a breach of this Agreement by the party failing to give such notice, in each case unless the underlying breach would independently result in a failure of the conditions set forth in Section 7.2 or 7.3 to be satisfied or give rise to such termination right.

     6.10 Dividends. After the date of this Agreement, each of MGIC and Radian shall coordinate with the other the declaration of any dividends in respect of MGIC Common Stock and Radian Common Stock and the record dates and payment dates relating thereto, it being the intention of the parties hereto that holders of Radian Common Stock shall not receive two dividends, or fail to receive one dividend, in any quarter with respect to their shares of

-41-

Radian Common Stock and any shares of MGIC Common Stock any such holder receives in exchange therefor in the Merger.

     6.11 Executive Officers; Succession. (a) In accordance with, and as provided in, the Bylaws of the Surviving Corporation (as amended by the Bylaw Amendment), (i) effective as of the Effective Time, ▇▇▇▇ ▇▇▇▇▇▇ shall continue to serve as Chairman of the Board of Directors and Chief Executive Officer of the Surviving Corporation and ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇ shall become President and Chief Operating Officer of the Surviving Corporation and (ii) (x) ▇▇. ▇▇▇▇▇▇▇ shall be the successor to ▇▇. ▇▇▇▇▇▇ as Chief Executive Officer of the Surviving Corporation, with such succession to become effective on (x) the date of the Surviving Corporation’s 2009 annual stockholders meeting (to be held on May 7, 2009) (provided that if the Effective Time occurs after July 1, 2007, the applicable date pursuant to this clause (x) shall be September 1, 2009) or (y) any such earlier date as of which ▇▇. ▇▇▇▇▇▇ ceases for any reason to serve in the position of Chief Executive Officer of the Surviving Corporation, and (y) ▇▇. ▇▇▇▇▇▇▇ shall be the successor to ▇▇. ▇▇▇▇▇▇ as Chairman of the Board of Directors of the Surviving Corporation, with such succession to become effective on the date of the Surviving Corporation’s 2010 annual stockholders meeting (to be held in May 2010) (the “2010 Annual Meeting”) or any such earlier date as of which ▇▇. ▇▇▇▇▇▇ ceases for any reason to serve in the position of Chairman of the Board of Directors of the Surviving Corporation (the “Chairman Succession Date”). Until the Chairman Succession Date, the office of Chairman of the Board shall be deemed to be a relationship of employee and employer as between the Chairman, on the one hand, and the Surviving Corporation, on the other. For the avoidance of doubt, occupany of the offices set forth in the preceding provisions of this Section 6.11(a) shall not occur unless immediately prior thereto the occupant contemplated above is an employee of the Surviving Corporation or one of its Affiliates, it being understood and agreed that neither ▇▇. ▇▇▇▇▇▇ nor ▇▇. ▇▇▇▇▇▇▇ may be terminated except as provided in Section 3.01(d) of the amended Bylaws as specified in Exhibit A.

     (b) On or prior to the Effective Time, the MGIC Board of Directors shall take such actions as are necessary to cause the persons listed on Schedule 6.11(b) to be elected or appointed as officers of the Surviving Corporation or one of its Affiliates in the capacities listed opposite their respective names on such Schedule as of the Effective Time, assuming that such persons are willing to serve in such capacities.

6.12(b), four (4) non-employee members of the current Radian Board. Two MGIC Directors and two Radian Directors shall be assigned to each of the three classes of the Board of Directors of the Surviving Corporation from and after the Effective Time as specified in Exhibit A. ▇▇. ▇▇▇▇▇▇ shall be designated and shall serve as the lead director of the Surviving Corporation Board of Directors (with the scope of the responsibilities of such lead director being as defined by such Board) until the date of the Surviving Corporation’s 2009 annual stockholders meeting, and shall be nominated by the Surviving Corporation Board of Directors to stand for election at such meeting to serve as a director of the Surviving Corporation Board of Directors for the class of directors whose terms expire at the annual meeting in 2012 (for the avoidance of doubt, no MGIC or Board age- or tenure-related retirement policies or provisions shall be deemed to prevent such continued Board service by ▇▇. ▇▇▇▇▇▇ through the fifth anniversary of the Effective Time). In the event that, prior to the Effective Time, any person so selected to serve on the Board of Directors of the Surviving Corporation after the Effective Time is unable or unwilling to serve in such position, the Board of Directors that selected such person shall designate another of its members to serve in such person’s stead in accordance with the provisions of the immediately preceding sentence. Prior to the Effective Time, MGIC shall cause its Board of Directors to approve and adopt resolutions effecting the Board composition contemplated by this Section 6.12.

     (b) As of the Effective Time, there shall be only five (5) Radian Directors on the Board of Directors of MGIC until an additional director selected by the Radian Directors is elected by MGIC’s stockholders. As promptly as practicable following the Closing Date (and in any event within ten business days of the Closing Date), the Corporation shall file with the SEC and furnish to its stockholders a proxy statement, and call and hold a special meeting of its stockholders with a record date that is the first business day following the Effective Time, for the sole purpose of voting upon and electing a sixth (6^th) Radian Director as contemplated by Section 6.12(b), and shall use its reasonable efforts in connection therewith. In the event that the sixth Radian Director is not elected at that meeting or any postponement of such meeting, the right to select such director shall continue and the Board of Directors shall take such action as it may reasonably determine acting in good faith to effect the Board of Directors’ composition contemplated by clause 6.12(a) above, and among other things the Radian Directors shall have the right to nominate an additional Radian director at MGIC’s 2008 annual meeting. The date when the sixth Radian Director is elected, whether occuring at the special meeting or at a later time, shall be the “Equalization Date.”

     (c) From and after the Effective Time until the 2010 Annual Meeting, each of the committees of the Board of Directors of MGIC shall be comprised of an equal number of MGIC Directors and Radian Directors and the chairpersons of such committees shall be drawn as nearly equally as possible from the MGIC Directors and the Radian Directors. From and after the Effective Time until the Equalization Date, the Board shall have an Executive Committee consisting of Messrs. ▇▇▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇ and ▇▇▇▇▇▇ (with any vacancy created by the loss of Messrs. ▇▇▇▇▇▇ or Jastrow filled by the affirmative majority vote of the MGIC Directors and any vacancy created by the loss of Messrs. Ibrahim or ▇▇▇▇▇▇ filled by the affirmative vote of a majority of the Radian Directors), which Executive Committee shall be formed and shall have a charter providing, together with such other matters as the parties may mutually agree, that such Committee shall approve (by majority vote of the entire such Committee) all non-ordinary course business to be brought before the full Board of Directors (other than such business as may

-43-

---

be proposed by the Corporation’s committees responsible for discharging the duties imposed by the rules of the NYSE on audit, compensation and corporate governance/nominating committees). Except as provided herein, the identity of the members of such committees and the chairmen of such committees shall otherwise be as mutually determined by the parties.

     (d) The term “MGIC Director” means (i) any person serving as a Director of MGIC on the date of this Agreement who continues as a Director of MGIC at the Effective Time and (ii) any person who becomes a Director of MGIC and who is designated as such by the MGIC Directors as defined in clause (i) (or their successors pursuant to this clause (ii)) prior to his or her election or appointment to the Board of Directors by a majority of such directors; and the term “Radian Director” means (A) any person serving as a Director of Radian on the date of this Agreement who becomes a Director of MGIC at the Effective Time and (B) any person who becomes a Director of MGIC and who is designated as such by the Radian Directors as defined in clause (A) (or their successors pursuant to this clause (B)) prior to his or her election or appointment to the Board of Directors by a majority of such directors. For the avoidance of doubt, the Board of the Surviving Corporation shall take such action as is necessary to elect or appoint to the Board of the Surviving Corporation any person who, in accordance with the immediately preceding sentence, is designated a MGIC Director or a Radian Director.

     6.13 Acquisition Proposals. (a) Until this Agreement has been terminated in accordance with Section 8.1, each Party agrees that it will not, and will cause its controlled Affiliates and its and their officers, directors, agents and representatives not to, directly or indirectly, (i) (A) initiate, solicit, encourage or knowingly facilitate inquiries or proposals with respect to, (B) engage or participate in any negotiations concerning, (C) provide any confidential or nonpublic information or data to or (D) have, or engage or participate in, any discussions with any Person relating to, any Acquisition Proposal, (ii) release or permit the release of any Person from, or waive or permit the waiver of any provisions of, or otherwise fail to exercise its rights under, any confidentiality, standstill or similar agreement to which such Party is a party or under which such Party has any rights with respect to the sale or transfer of the voting securities or any material portion of the assets of such Party, (iii) withdraw, modify or qualify (or propose to withdraw, modify or qualify) in any manner adverse to the other Party the recommendation by such Party’s Board of Directors of this Agreement to its stockholders or take any action or make any statement in connection with such Party’s meeting of stockholders inconsistent with such recommendation, including any action to approve, recommend or endorse, or to propose to approve, recommend or endorse, any Acquisition Proposal (collectively, a “Change in Recommendation”), or (iv) enter into any agreement, letter of intent, agreement-in-principle, acquisition agreement or other instrument contemplating or otherwise relating to any Acquisition Proposal or requiring such Party to abandon, terminate or fail to consummate any of the transactions contemplated hereby, including the Merger.

     (b) Notwithstanding Section 6.13(a), prior to approval of the transactions contemplated by this Agreement at its meeting of stockholders to be held pursuant to Section 6.3, a Party (the “Acting Party”) may, and may permit its Affiliates and its and their appropriate officers, directors agents and representatives to furnish or cause to be furnished nonpublic information or data and participate in such negotiations or discussions with, any Person in response to an unsolicited, bona fide and written Acquisition Proposal that is submitted to the Acting Party after the date of this Agreement and prior to the approval of the transactions

-44-

---

contemplated by this Agreement at its meeting of stockholders to be held pursuant to Section 6.3, and may withdraw, modify or qualify the recommendation by such Party’s Board of Directors of this Agreement to its stockholders in connection therewith, if and so long as (A) none of the Acting Party, any of its controlled Affiliates or any of its or their officers, directors, agents or representatives has violated any of the provisions of this Section 6.13, (B) the Board of Directors of the Acting Party concludes in good faith (after receiving the advice of its outside counsel and its financial advisors) that failure to take such actions would result in a violation of its fiduciary duties under applicable law, (C) at least twenty-four (24) hours prior to furnishing or causing to be furnished nonpublic information or data to, and participating in such negotiations or discussions with, such Person, the Acting Party provides the other Party with written notice of the identity of such Person and of the Acting Party’s intention to participate in discussions or negotiations with, or to furnish or disclose nonpublic information to, such Person, (D) prior to providing any nonpublic information to such Person, the Acting Party shall have entered into a confidentiality and standstill agreement with such Person (a copy of which it shall have provided to the other Party) on terms no less restrictive upon such Person, in any respect, than the terms applicable to the other Party under the Confidentiality Agreement, which confidentiality and standstill agreement shall not provide such Person with any exclusive right to negotiate with the Acting Party or have the effect of preventing the Acting Party from satisfying its obligations under this Agreement, (E) at least twenty-four (24) hours prior to furnishing or causing to be furnished nonpublic information or data to such Person, the Acting Party furnishes such information to the other Party (to the extent such information has not been previously delivered or made available by the Acting Party to the other Party), and (F) prior to so withdrawing, modifying or qualifying the recommendation by its Board of Directors of this Agreement, the Acting Party gives the other Party five business days' prior written notice of its intention to do so (unless at the time such notice is otherwise required to be given there are less than five business days prior to the Acting Party’s stockholders meeting, in which case the Acting Party shall provide as much notice as is reasonably practicable), and during such time, the Acting Party, if requested by the other Party, shall have engaged in good faith negotiations to amend this Agreement (including by making its officers and its financial and legal advisors reasonably available to negotiate) such that the Board of Directors of the Acting Party may continue to recommend the approval of this Agreement.

     (c) Each Party shall, and shall cause its controlled Affiliates and its and their appropriate officers, directors, agents and representatives to, immediately cease and cause to be terminated any activities, discussions or negotiations conducted before the date of this Agreement with any Persons other than Radian or MGIC, as the case dictates, with respect to any Acquisition Proposal. Each Party will promptly (within one day) request each Person who has heretofore executed a confidentiality agreement in connection with its consideration of acquiring such Party or any portion thereof (including any of its Subsidiaries) to return all nonpublic information heretofore furnished to such Person by or on behalf of such Party and shall advise the other Party of the particulars of such request. Each Party will (i) promptly (within 24 hours) advise the other Party following receipt of any request for information, any Acquisition Proposal or any inquiry which could reasonably be expected to lead to an Acquisition Proposal, and the substance thereof (including the terms and conditions of, and the identity of the Person making, such request, Acquisition Proposal or inquiry), (ii) promptly (within 24 hours) provide the other Party with all written materials received by such Party in connection with the foregoing, and (iii) keep the other Party apprised of any related developments, discussions and negotiations on a

     (e) Nothing contained in this Agreement shall prevent a Party or its Board of Directors from complying with Rule 14d-9 and Rule 14e-2 under the 1934 Act with respect to an Acquisition Proposal; provided, that such Rules will in no way eliminate or modify the effect that any action pursuant to such Rules would otherwise have under this Agreement.

     (f) Any violation of this Section 6.13 by a Party’s Affiliates or a Party’s or any of its controlled Affiliates’ appropriate officers, directors, agents and representatives shall be deemed to be a breach of this Agreement by such Party.

     6.14 Exemption from Liability Under Section 16(b). Assuming that Radian delivers to MGIC the Section 16 Information in a timely fashion, the Board of Directors of MGIC, or a committee of Non-Employee Directors thereof (as such term is defined for purposes of Rule 16b-3(d) under the Exchange Act), shall adopt a resolution providing that the receipt by the Radian Insiders of MGIC Common Stock in exchange for shares of Radian Common Stock and the settlement or conversion of Radian Equity Awards (including the receipt of options on MGIC Common Stock upon conversion of options on Radian Common Stock), in each case pursuant to the transactions contemplated hereby and to the extent such securities are listed in the Section 16 Information, are intended to be exempt from liability pursuant to Section 16(b) under the Exchange Act. “Section 16 Information” shall mean information accurate in all respects

     (d) For purposes of this Section 8.2, a “Pre-Termination Takeover Proposal Event” shall be deemed to occur if, prior to the event giving rise to the right to terminate this Agreement, a bona fide Acquisition Proposal shall have been made known to Radian (in the case of an Acquisition Proposal relating to Radian) or shall have been made known to MGIC (in the case of any Acquisition Proposal relating to MGIC) or has been made directly to its stockholders generally or any person shall have publicly announced an Acquisition Proposal or an intention (whether or not conditional) to make an Acquisition Proposal (the term Acquisition Proposal, as used in the definition of Acquisition Proposal for purposes of this Section 8.2, and as used in this Section 8.2, shall have the same meaning set forth in Section 6.13 except that the references to “more than 15%” contained in the definition of Alternative Transaction shall be deemed to be references to “50% or more” and such definition shall not include any merger, share exchange, consolidation, business combination or similar transaction where (i) the holders of shares of such party immediately prior to such transaction (or series of related transactions) would continue, in the aggregate, to own at least a majority of the outstanding shares of common stock and the outstanding voting power of the surviving or resulting entity (or its ultimate parent) in the transaction (or series of related transactions) immediately after the consummation thereof in substantially the same proportion as such holders held the shares of such party’s common stock immediately prior to the consummation thereof and (ii) such party would retain at least a majority of the surviving or resulting entity’s (or its ultimate parent’s) board of directors).

     (f) Each of MGIC and Radian acknowledges that the agreements contained in this Section 8.2 are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, the other party would not enter into this Agreement; accordingly, if MGIC or Radian, as the case may be, fails promptly to pay the amount due pursuant to this Section 8.2, and, in order to obtain such payment, the other party commences a suit which results in a judgment against the non-paying party for the fee set forth in this Section 8.2, such non-paying party shall pay the costs and expenses of the other party (including attorneys’ fees and expenses) in connection with such suit.

Any agreement on the part of a party hereto to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of such party, but such extension or waiver or failure to insist on strict compliance with an obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure.

Exhibit B

Form of Affiliate Letter

MGIC Investment Corporation MGIC Plaza ▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇ Ladies and Gentlemen:

     I have been advised that as of the date hereof I may be deemed to be an “affiliate” of Radian Group Inc., a Delaware corporation (“Radian”), as the term “affiliate” is defined for purposes of paragraphs (c) and (d) of Rule 145 of the rules and regulations (the “Rules and Regulations”) of the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Act”). I have been further advised that pursuant to the terms of the Agreement and Plan of Merger dated as of February 6, 2007 (the “Merger Agreement”), by and between Radian, and MGIC Investment Corporation, a Wisconsin corporation (“MGIC”), Radian shall be merged with and into MGIC (the “Merger”). All terms used in this letter but not defined herein shall have the meanings ascribed thereto in the Merger Agreement.

         I represent, warrant and covenant to MGIC that in the event I receive any MGIC Common Stock as a result of the Merger:

     (a)    The MGIC Common Stock to be received by me as a result of the Merger will be taken for my own account, and not for others, directly or indirectly, in whole or part, and I shall not make any sale, transfer or other disposition of MGIC Common Stock in violation of the Act or the Rules and Regulations.

     (b)     I have carefully read this letter and the Merger Agreement and discussed its requirements and other applicable limitations upon my ability to sell, transfer or otherwise dispose of MGIC Common Stock to the extent I believed necessary with my counsel or counsel for Radian.

     (c)    I have been advised that the issuance of MGIC Common Stock to me pursuant to the Merger will be registered with the Commission under the Act on a Registration Statement on Form S-4. However, I have also been advised that, since at the time the Merger will be submitted for a vote of the stockholders of Radian I may be deemed to have been an affiliate of Radian and the distribution by me of MGIC Common Stock has not been registered under the Act, I may not sell, transfer or otherwise dispose of MGIC Common Stock issued to me in the Merger unless (i) such sale, transfer or other disposition has been registered under the Act, (ii) such sale, transfer or other disposition is made in conformity with the volume and other limitations of Rule 145 promulgated by the Commission under the Act, or (iii) in the opinion of counsel reasonably acceptable to MGIC, such sale, transfer or other disposition is otherwise exempt from registration under the Act.

     (d)    I understand that MGIC is under no obligation to register the sale, transfer or other disposition of MGIC Common Stock by me or on my behalf under the Act or to take any

---

other action necessary in order to make compliance with an exemption from such registration available.

     (e)      I also understand that stop transfer instructions will be given to MGIC’s transfer agents with respect to MGIC Common Stock and that there will be placed on the certificates for MGIC Common Stock issued to me, or any substitutions therefor, a legend stating in substance:

     (f)      I also understand that unless the transfer by me of my MGIC Common Stock has been registered under the Act or is a sale made in conformity with the provisions of Rule 145, MGIC reserves the right to put the following legend on the certificates issued to my transferee:

     It is understood and agreed that the legends set forth above shall be removed by delivery of substitute certificates without such legend, and/or the issuance of a letter to MGIC’s transfer agent removing such stop transfer instructions, and the above restrictions on sale will cease to apply, if (A) one year (or such other period as may be required by Rule 145(d)(2) under the Securities Act or any successor thereto) shall have elapsed from the Closing Date and the provisions of such Rule are then available to me; or (B) if two years (or such other period as may be required by Rule 145(d)(3) under the Securities Act or any successor thereto) shall have elapsed from the Effective Date and the provisions of such Rule are then available to me; or (C) I shall have delivered to MGIC (i) a copy of a letter from the staff of the Commission, or an opinion of counsel in form and substance reasonably satisfactory to MGIC, or other evidence reasonably satisfactory to MGIC, to the effect that such legend and/or stop transfer instructions are not required for purposes of the Securities Act or (ii) evidence or representations reasonably satisfactory to MGIC that the securities represented by such certificates are being or have been transferred in a transaction made in conformity with the provisions of Rule 145 under the Securities Act or pursuant to an effective registration under the Securities Act.

     I recognize and agree that the foregoing provisions also apply to (i) my spouse, (ii) any relative of mine or my spouse occupying my home, (iii) any trust or estate in which I, my

spouse or any such relative owns at least 10% beneficial interest or of which any of us serves as trustee, executor or in any similar capacity and (iv) any corporate or other organization in which I, my spouse or any such relative owns at least 10% of any class of equity securities or of the equity interest.

     By its acceptance hereof, MGIC agrees, for a period of two years after the Effective Time that it, as the Surviving Corporation, will use commercially reasonable efforts to file on a timely basis all reports required to be filed by it pursuant to Section 13 of the Exchange Act, so that the public information provisions of Rule 144(c) under the Securities Act are satisfied and the resale provisions of Rules 145(d)(1) and (2) under the Securities Act are therefore available to the undersigned in the event the undersigned desires to transfer any MGIC Common Stock issued to the undersigned in the Merger.

     It is understood and agreed that this Letter Agreement shall terminate and be of no further force and effect if the Merger Agreement is terminated in accordance with its terms.

     Execution of this letter should not be construed as an admission on my part that I am an “affiliate” of Radian as described in the first paragraph of this letter or as a waiver of any rights I may have to object to any claim that I am such an affiliate on or after the date of this letter.
