Ladies and Gentlemen:

MGIC Investment Corporation, a Wisconsin corporation (the “Company”), proposes to issue and sell to the several underwriters named in Schedule A (the “Underwriters”) $450,000,000 in aggregate principal amount of its 2.00% Convertible Senior Notes due 2020 (the “Firm Securities”).  In addition, the Company has granted to the Underwriters an option to purchase up to an additional $50,000,000 in aggregate principal amount of its 2.00% Convertible Senior Notes due 2020 (the “Optional Securities” and, together with the Firm Securities, the “Securities”).  Goldman, Sachs & Co. has agreed to act as representative of the several Underwriters (in such capacity, the “Representative”) in connection with the offering and sale of the Securities.  The terms Representative and Underwriters shall mean either the singular or plural as the context requires.

The Securities will be convertible on the terms, and subject to the conditions, set forth in the indenture, dated as of October 15, 2000 (the “Base Indenture”), between the Company and U.S. Bank National Association, as successor trustee (the “Trustee”), and the second supplemental indenture, to be dated as of the Closing Date (as defined herein), under which the Securities will be issued (the “Supplemental Indenture” and, together with the Base Indenture, the “Indenture”).  As used herein, “Conversion Shares” means the shares of common stock, par value $1.00 per share, of the Company (the “Common Stock”) to be received by the holders of the Securities upon conversion of the Securities pursuant to the terms of the Securities and the Indenture.  This Agreement, the Indenture and the Securities are referred to herein collectively as the “Operative Documents.”

The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Securities Act”), a registration statement on Form S-3 (File No. 333-166175), including a prospectus, relating to, among other securities, the Securities.  Such registration statement, as amended, including the financial statements, exhibits and schedules thereto, at the time it became effective, including any required information deemed to be a part thereof at the time of effectiveness pursuant to Rule 430A under the Securities Act or the Securities Exchange Act of 1934 and the rules and regulations promulgated thereunder (collectively, the “Exchange Act”), is called the “Registration Statement.”  The base prospectus filed as part of the Registration Statement, in the form in which it has most recently been filed with the Commission on or prior to the date of this Agreement relating to the Securities, is hereinafter called the “Basic Prospectus”;  any preliminary prospectus (included any preliminary

prospectus supplement) relating to the Securities filed with the Commission pursuant to Rule 424(b) under the Securities Act is hereinafter called a “Preliminary Prospectus.”  The term “Prospectus” shall mean the final prospectus relating to the Securities that is first filed pursuant to Rule 424(b) after the date and time that this Agreement is executed and delivered by the parties hereto.  Any reference herein to the Registration Statement, the Basic Prospectus, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3, as of the effective date of the Registration Statement or as of the date of such prospectus, as the case may be. All references in this Agreement to the Registration Statement, a Preliminary Prospectus, the Prospectus, or any amendments or supplements to any of the foregoing, shall include any copy thereof filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system (“EDGAR”).

The Company hereby agrees with the Underwriters as follows:

Section 1.  Representations, Warranties and Covenants of the Company.

(b)  Each Preliminary Prospectus and the Prospectus when filed complied in all material respects with the Securities Act and the rules thereunder.  Each of the Registration Statement and any post-effective amendment thereto, at the time it became effective and at the date hereof, complied and will comply in all material respects with the Securities Act and the Trust Indenture Act of 1939, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Trust Indenture Act”) and did not and will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading.  The Prospectus (including any Prospectus wrapper), as amended or supplemented, as of its date, at the time of any filing pursuant to Rule 424(b), at the Closing Date and at any Subsequent Closing Date (as defined herein), will not contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the

denominations in which the Optional Securities are to be registered and (iii) the time, date and place at which such Securities will be delivered (which time and date may be simultaneous with, but not earlier than, the Closing Date; and in such case the term “Closing Date” shall refer to the time and date of delivery of the Firm Securities and the Optional Securities).  Such time and date of delivery, if subsequent to the Closing Date, is called a “Subsequent Closing Date” and shall be determined by the Representative.  Such date may be the same as the Closing Date but not earlier than the Closing Date nor later than 10 business days after the date of such notice.  If any Optional Securities are to be purchased, each Underwriter agrees, severally and not jointly, to purchase the principal amount of Optional Securities (subject to such adjustments to eliminate fractional amount as the Representative may determine) that bears the same proportion to the total principal amount of Optional Securities to be purchased as the principal amount of Firm Securities set forth on Schedule A opposite the name of such Underwriter bears to the total principal amount of Firm Securities.

(d)  Public Offering of the Securities.  The Representative hereby advises the Company that the Underwriters intend to offer for sale to the public, as described in the Prospectus, their respective portions of the Securities as soon after this Agreement has been executed and delivered as the Representative, in its sole judgment, has determined is advisable and practicable.

(e)  Payment for the Securities.  Payment for the Securities shall be made at the Closing Date (and, if applicable, at any Subsequent Closing Date) by wire transfer of immediately available funds to the order of the Company.

It is understood that the Representative has been authorized, for its own account and the accounts of the several Underwriters, to accept delivery of and receipt for, and make payment of the purchase price for, the Firm Securities and any Optional Securities the Underwriters have agreed to purchase.  Goldman, Sachs & Co., individually and not as the Representative of the Underwriters, may (but shall not be obligated to) make payment for any Securities to be purchased by any Underwriter whose funds shall not have been received by the Representative by the Closing Date or any Subsequent Closing Date, as the case may be, for the account of such Underwriter, but any such payment shall not relieve such Underwriter from any of its obligations under this Agreement.

(f)  Delivery of the Securities.  The Company shall deliver, or cause to be delivered, to the Representative for the accounts of the several Underwriters the Firm Securities at the Closing Date, against the irrevocable release of a wire transfer of immediately available funds for the amount of the purchase price therefor.  The Company shall also deliver, or cause to be delivered, to the Representative for the accounts of the several Underwriters, the Optional Securities the Underwriters have agreed to purchase at the Closing Date or any Subsequent Closing Date, as the case may be, against the irrevocable release of a wire transfer of immediately available funds for the amount of the purchase price therefor.  Delivery of the Securities shall be made through the facilities of The Depository Trust Company unless the Representative shall otherwise instruct.  Time shall be of the essence, and delivery at the time and place specified in this Agreement is a further condition to the obligations of the Underwriters.

(g)  Delivery of Prospectus to the Underwriters.  Not later than 10:00 a.m. on the second business day following the date the Securities are first released by the Underwriters for sale to the public, the Company shall deliver or cause to be delivered, copies of the Prospectus in such quantities and at such places as the Representative shall request.

Section 3.  Covenants of the Company

The Company covenants and agrees with each Underwriter as follows:

(a)  Representative’s Review of Proposed Amendments and Supplements.  During the period beginning on the Applicable Time and ending on the later of the Closing Date or such date, as in the opinion of counsel for the Underwriters, the Prospectus is no longer required by law to be delivered in connection with sales by an Underwriter or dealer, including in circumstances where such requirement may be satisfied pursuant to Rule 172 (the “Prospectus Delivery Period”), prior to amending or supplementing the Registration Statement, the Disclosure Package or the Prospectus, subject to Section 3(e), the Company shall furnish to the Representative for review a copy of each such proposed amendment or supplement, and the Company shall not file, use or distribute any such proposed amendment or supplement to which the Representative reasonably objects; provided, however, that the provisions of this subsection (a) shall not apply to any of the Company’s periodic filings under the Exchange Act described in Section 3(c), copies of which filings in substantially final form the Company has delivered to you in advance of their transmission to the Commission for filing and provided you a reasonable opportunity to comment thereon.

(b)  Securities Act Compliance.  After the date of this Agreement, the Company shall promptly advise the Representative in writing (i) of the receipt of any comments of, or requests for additional or supplemental information from, the Commission relating to the Registration Statement, (ii) of the time and date of any filing of any post-effective amendment to the Registration Statement or any amendment or supplement to any Preliminary Prospectus, the Prospectus or any Issuer Free Writing Prospectus, (iii) of the time and date that any post-effective amendment to the Registration Statement becomes effective, (iv) of the receipt by the Company of any notice of objection of the Commission to the use of the Registration Statement or any post-effective amendment thereto pursuant to Rule 401(g)(2) under the Securities Act and (v) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any order or notice preventing or suspending the use of the Registration Statement, any Preliminary Prospectus, the Prospectus or any Issuer Free Writing prospectus, or of any proceedings to remove, suspend or terminate from listing or quotation the Common Stock or the Securities from any securities exchange upon which they are listed for trading or included or designated for quotation, or of the threatening or initiation of any proceedings for any of such purposes.  The Company shall use its reasonable best efforts to prevent the issuance of any such stop order or notice of prevention or suspension of such use.  If the Commission shall enter any such stop order or issue any such notice at any time, the Company will use its reasonable best efforts to obtain the lifting or reversal of such order or notice at the earliest possible moment, or, subject to Section 3(a), will file an amendment to the Registration Statement or will file a new registration statement and use its reasonable best efforts to have such amendment or new registration statement declared effective as soon as practicable.  Additionally, the Company agrees that it shall comply with the provisions of Rules 424(b), 430A, 433, as applicable, under the Securities Act, including with respect to the timely filing of documents thereunder, and the Company shall pay the registration fee for this offering within the time period required by Rule 456(b)(1) under the Securities Act (without giving effect to the proviso therein) and in any event prior to the Closing Date.

(c)  Exchange Act Compliance.  During the Prospectus Delivery Period, the Company will file all documents required to be filed with the Commission pursuant to Section 13(a), 13(c),

12

14 or 15(d) of the Exchange Act in the manner and within the time periods required by the Exchange Act.

(d)  Amendments and Supplements to the Registration Statement, Disclosure Package and Prospectus and Other Securities Act Matters.  If, during the Prospectus Delivery Period, any event or development shall occur or condition exist as a result of which the Disclosure Package, the Prospectus or any Issuer Free Writing Prospectus, as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein in the light of the circumstances under which they were made or then prevailing, as the case may be, not misleading, or if it shall be necessary to amend or supplement the Disclosure Package, the Prospectus or any Issuer Free Writing Prospectus in order to make the statements therein, in the light of the circumstances under which they were made or then prevailing, as the case may be, not misleading, or if in the opinion of the Representative it is otherwise necessary to amend or supplement the Registration Statement, the Disclosure Package, the Prospectus or any Issuer Free Writing Prospectus, or to file a new registration statement, in order to comply with law, including in connection with the delivery of the Prospectus, the Company agrees to (i) notify the Representative of any such event or condition and (ii) promptly prepare (subject to Sections 3(a) and 3(e) hereof), file with the Commission (and use its reasonable best efforts to have any amendment to the Registration Statement or any new registration statement to be declared effective) and furnish at its own expense to the Underwriters and to dealers, amendments or supplements to the Registration Statement, the Disclosure Package, the Prospectus or any Issuer Free Writing Prospectus, or any new registration statement, necessary in order to make the statements in the Disclosure Package, the Prospectus or any Issuer Free Writing Prospectus as so amended or supplemented, in the light of the circumstances under which they were made or then prevailing, as the case may be, not misleading or so that the Registration Statement, the Disclosure Package, the Prospectus or any Issuer Free Writing Prospectus, as amended or supplemented, will comply with law.

(e)  Free Writing Prospectuses.  Before using, authorizing, approving, referring to or filing any Issuer Free Writing Prospectus, the Company will furnish to the Representative and counsel for the Underwriters a copy of the proposed Issuer Free Writing Prospectus for review and will not use, authorize, approve, refer to or file any such Issuer Free Writing Prospectus to which the Representative reasonably objects.

(f)  Copies of the Registration Statement, the Prospectus and any Issuer Free Writing Prospectus.  The Company will furnish to the Representative and counsel for the Underwriters signed copies of the Registration Statement and any amendments thereto (including, in each case, exhibits thereto) and, so long as delivery of a prospectus by an Underwriter or dealer may be required by the Securities Act, as many copies of each Preliminary Prospectus, the Prospectus and any supplement thereto and the Disclosure Package and any Issuer Free Writing Prospectus as the Representative may reasonably request.

(g)  Blue Sky Compliance.  The Company shall cooperate with the Representative and counsel for the Underwriters to qualify or register the Securities for sale under (or obtain exemptions from the application of) the state securities or blue sky laws or Canadian provincial securities laws or other foreign laws of those jurisdictions designated by the Representative, shall comply with such laws and shall continue such qualifications, registrations and exemptions in effect so long as required for the distribution of the Securities.  The Company shall not be required to qualify as a foreign corporation or to take any action that would subject it to general service of process in any such jurisdiction where it is not presently qualified or where it would be

13

subject to taxation as a foreign corporation, other than those arising out of the offering or sale of the Securities in any jurisdiction where it is not now so subject.  The Company will advise the Representative promptly of the suspension of the qualification or registration of (or any such exemption relating to) the Securities for offering, sale or trading in any jurisdiction or any initiation or threat of any proceeding for any such purpose, and in the event of the issuance of any order suspending such qualification, registration or exemption, the Company shall use its reasonable best efforts to obtain the withdrawal thereof at the earliest possible moment.

(h)  DTC.  The Company will cooperate with the Representative and use its reasonable best efforts to permit the Securities to be eligible for clearance and settlement through The Depository Trust Company.

(i)  Use of Proceeds.  The Company shall apply the net proceeds from the sale of the Securities sold by it in the manner described under the caption “Use of Proceeds” in the Disclosure Package and the Prospectus.

(j)  Earnings Statement.  As soon as practicable, the Company will make generally available to its security holders and to the Representative an earnings statement (which need not be audited) covering the twelve-month period ending March 31, 2014 that satisfies the provisions of Section 11(a) of the Securities Act and Rule 158 under the Securities Act.

(k)  Transfer Agent.  The Company shall engage and maintain, at its expense, a registrar and transfer agent for the Common Stock.

(l)  Available Conversion Shares.  The Company will reserve and keep available at all times, free of pre-emptive rights, the full number of Conversion Shares.

(m)  Conversion Price.  Between the date hereof and the Closing Date, the Company will not do or authorize any act or thing that would result in an adjustment of the conversion price.

(n)  Periodic Reporting Obligations.  During the Prospectus Delivery Period, the Company shall file, on a timely basis, with the Commission and the New York Stock Exchange all reports and documents required to be filed under the Exchange Act.

(o)  Listing.  The Company will use its reasonable best efforts to reserve for listing, subject to notice of issuance, the Conversion Shares on the New York Stock Exchange.

(p)  Agreement Not to Offer or Sell Additional Securities.  During the period commencing on the date hereof and ending on the 90th day following the date of the Prospectus, the Company will not, without the prior written consent of the Representative (which consent may be withheld at the sole discretion of the Representative), directly or indirectly, sell, offer, contract or grant any option to sell, pledge, transfer or establish an open “put equivalent position” or liquidate or decrease a “call equivalent position” within the meaning of Rule 16a-1(h) under the Exchange Act, or otherwise dispose of or transfer (or enter into any transaction that is designed to, or might reasonably be expected to, result in the disposition of), or announce the offering of, or file any registration statement under the Securities Act in respect of, any shares of Common Stock, options or warrants to acquire shares of the Common Stock or securities exchangeable or exercisable for or convertible into shares of Common Stock (other than as contemplated by this Agreement with respect to the Securities); provided, however, that the Company may issue shares of its Common Stock or options to purchase its Common Stock, or Common Stock upon exercise

14

of options, pursuant to any stock option, stock bonus or other stock plan or arrangement described in the Prospectus.  Notwithstanding the foregoing, if (x) during the last 17 days of the 90-day restricted period the Company issues an earnings release or material news or a material event relating to the Company occurs, or (y) prior to the expiration of the 90-day restricted period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the 90-day period, the restrictions imposed in this clause shall continue to apply until the expiration of the 18-day period beginning on the date of the issuance of the earnings release or the occurrence of the material news or material event in writing, such extension.  The Company will provide the Representative and any co-managers and each individual subject to the restricted period pursuant to the lockup letters described in Section 5(g) with prior notice of any such announcement that gives rise to an extension of the restricted period.

(q)   Compliance with Sarbanes-Oxley Act.  The Company will comply with all applicable securities and other laws, rules and regulations, including, without limitation, the Sarbanes-Oxley Act, and use its best efforts to cause the Company’s directors and officers, in their capacities as such, to comply with such laws, rules and regulations, including, without limitation, the provisions of the Sarbanes-Oxley Act.

(r)  Future Reports to Shareholders.  The Company will make available to its shareholders as soon as practicable after the end of each fiscal year an annual report (including a balance sheet and statements of income, shareholders’ equity and cash flows of the Company and its consolidated subsidiaries certified by independent public accountants) and, as soon as practicable after the end of each of the first three quarters of each fiscal year (beginning with the fiscal quarter ending after the effective date of the Registration Statement), to make available to its shareholders consolidated summary financial information of the Company and its subsidiaries for such quarter in reasonable detail.

(s)  Investment Limitation.  The Company shall not invest or otherwise use the proceeds received by the Company from its sale of the Securities in such a manner as would require the Company or any of its subsidiaries to register as an investment company under the Investment Company Act.

(t)  No Manipulation of Price.  The Company will not take, directly or indirectly, any action designed to cause or result in, or that has constituted or might reasonably be expected to constitute, under the Exchange Act or otherwise, the stabilization or manipulation of the price of any securities of the Company to facilitate the sale or resale of the Securities.

(u)  New Lock-Up Agreements.  The Company will enforce all agreements between the Company and any of its security holders to be entered into pursuant to this Agreement that prohibit the sale, transfer, assignment, pledge or hypothecation of any of the Company’s securities.  In addition, the Company will direct the transfer agent to place stop transfer restrictions upon any such securities of the Company that are bound by such “lock-up” agreements for the duration of the periods contemplated in such agreements.

(v)  Final Term Sheet.  The Company will prepare a final term sheet, containing solely a description of the Securities and the offering thereof, in the form approved by you and attached as Schedule C hereto (the “Final Term Sheet”).

15

(w)  Record Retention.  The Company will, pursuant to reasonable procedures developed in good faith, retain copies of each Issuer Free Writing Prospectus that is not filed with the Commission in accordance with Rule 433 under the Securities Act.

(x)  New Shelf Registration Statement.  If by the third anniversary (the “Renewal Deadline”) of the initial effective date of the Registration Statement, any of the Securities remain unsold by the Underwriters, the Company will use reasonable best efforts to file, if it has not already done so and is eligible to do so, a new automatic shelf registration statement relating to the Securities, in a form reasonably satisfactory to you.  If, at the Renewal Deadline, the Company is no longer eligible to file an automatic shelf registration statement, the Company will use reasonable best efforts to file, if it has not already done so, a new shelf registration statement relating to the Securities, in a form reasonably satisfactory to you and will use its reasonable best efforts to cause such registration statement to be declared effective within 180 days after the Renewal Deadline.  The Company will use reasonable best efforts to take all other action reasonably necessary to permit the public offering and sale of the Securities to continue, in all material respects, as contemplated in the expired registration statement relating to the Securities.  References in Section 1 hereof to the Registration Statement shall include, as applicable, such new automatic shelf registration statement or such new shelf registration statement, as the case may be.

The Representative, on behalf of the several Underwriters, may, in its sole discretion, waive in writing the performance by the Company of any one or more of the foregoing covenants or extend the time for their performance.

Company hereby acknowledges that the only information that the Underwriters have furnished to the Company expressly for use in the Registration Statement, any Preliminary Prospectus or the Prospectus (or any amendment or supplement thereto) or any Free Writing Prospectus, the Final Term Sheet or any Non-FWP Road Show are the information appearing in the table in the first paragraph under the caption “Underwriting” in the Prospectus relating to the principal amount of Securities to be purchased by each Underwriter, the percentage appearing in the fourth paragraph under the caption “Underwriting” in the Prospectus relating to securities dealer discounts and the information contained in the eighth paragraph under the caption “Underwriting” in the Prospectus relating to stabilization activities.  The indemnity agreement set forth in this Section 8(b) shall be in addition to any liabilities that each Underwriter may otherwise have.

(c)  Notifications and Other Indemnification Procedures.  Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof (in such detail as may be available to such indemnified person), but the failure to so notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above.  In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in, and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties.  Upon receipt of notice from the indemnifying party to such indemnified party of such indemnifying party’s election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 8 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (other than local counsel), reasonably approved by the indemnifying party (or by the Representative in the case of Section 8(b)), representing the indemnified parties who are parties to such action) or (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action, in each of which cases the fees and expenses of counsel shall be at the expense of the indemnifying party.

(d)  Settlements.  The indemnifying party under this Section 8 shall not be liable for any settlement of any proceeding effected without its written consent, which shall not be withheld unreasonably, but if settled with such consent or if there is a final judgment for the plaintiff, the

21

indemnifying party agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or judgment.  Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by Section 8(c) hereof, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement.  No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent (x) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding and (y) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

Section 9.  Contribution

If the indemnification provided for in Section 8 is for any reason unavailable to or otherwise insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount paid or payable by such indemnified party, as incurred, as a result of any losses, claims, damages, liabilities or expenses referred to therein (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company, on the one hand, and the Underwriters, on the other hand, in connection with the statements or omissions that resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations.  The relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company, and the total underwriting discount received by the Underwriters, in each case as set forth on the front cover page of the Prospectus, bear to the aggregate initial public offering price of the Securities as set forth on such cover.  The relative fault of the Company, on the one hand, and the Underwriters, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company, on the one hand, or the Underwriters, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in Section 8(c), any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim.

22

The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 9 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 9.

Notwithstanding the provisions of this Section 9, no Underwriter shall be required to contribute any amount in excess of the underwriting commissions received by such Underwriter in connection with the Securities underwritten by it and distributed to the public.  No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.  The Underwriters’ obligations to contribute pursuant to this Section 9 are several, and not joint, in proportion to their respective underwriting commitments as set forth opposite their names in Schedule A.  For purposes of this Section 9, each director, officer, employee and agent of an Underwriter and each person, if any, who controls an Underwriter within the meaning of the Securities Act or the Exchange Act shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act shall have the same rights to contribution as the Company.

Section 10.  Default of One or More of the Several Underwriters

If, on the Closing Date or any Subsequent Closing Date, as the case may be, any one or more of the several Underwriters shall fail or refuse to purchase Securities that it or they have agreed to purchase hereunder on such date, and the aggregate principal amount number of Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase does not exceed 10% of the aggregate principal amount of the Securities to be purchased on such date, the other Underwriters shall be obligated, severally, in the proportions that the principal amount of Firm Securities set forth opposite their respective names on Schedule A bears to the aggregate principal amount of Firm Securities set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as may be specified by the Representative with the consent of the non-defaulting Underwriters, to purchase the Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date. If, on the Closing Date or any Subsequent Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Securities and the aggregate principal amount of Securities with respect to which such default occurs exceeds 10% of the aggregate principal amount of Securities to be purchased on such date, and arrangements satisfactory to the Representative and the Company for the purchase of such Securities are not made within 48 hours after such default, this Agreement shall terminate without liability of any non-defaulting party to any other party except that the provisions of Section 4, Section 6, Section 8, Section 9 and Section 14 shall at all times be effective and shall survive such termination.  In any such case either the Representative or the Company shall have the right to postpone the Closing Date or any Subsequent Closing Date, as the case may be, but in no event for longer than seven days in order that the required changes, if any, to the Registration Statement and the Prospectus or any other documents or arrangements may be effected.

As used in this Agreement, the term “Underwriter” shall be deemed to include any person substituted for a defaulting Underwriter under this Section 10.  Any action taken under this Section 10 shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

23

Section 11.  Termination of this Agreement

On or prior to the Closing Date this Agreement may be terminated by the Representative by notice given to the Company if at any time (i) trading or quotation in any of the Company’s securities shall have been suspended or limited by the Commission or by the New York Stock Exchange, or trading in securities generally on the New York Stock Exchange shall have been suspended or limited, or minimum or maximum prices shall have been generally established by the Commission or on such stock exchange; (ii) a general banking moratorium shall have been declared by any federal or New York authority or a material disruption in commercial banking or securities settlement or clearance services in the United States has occurred; or (iii) there shall have occurred any outbreak or escalation of national or international hostilities or declaration of a national emergency or war by the United States or any crisis or calamity, or any change in the United States or international financial markets, or any substantial change or development involving a prospective substantial change in United States’ or international political, financial or economic conditions, as in the judgment of the Representative is material and adverse and makes it impracticable or inadvisable to market the Securities in the manner and on the terms described in the Disclosure Package and the Prospectus or to enforce contracts for the sale of securities.  Any termination pursuant to this Section 11 shall be without liability on the part of (a) the Company to any Underwriter, except that the Company shall be obligated to reimburse the expenses of the Representative and the Underwriters pursuant to Sections 4 and Section 6 hereof or (b) any Underwriter to the Company.

Section 12.  No Advisory or Fiduciary Responsibility

The Company acknowledges and agrees that: (i) the purchase and sale of the Securities pursuant to this Agreement, including the determination of the public offering price of the Securities and any related discounts and commissions, is an arm’s-length commercial transaction between the Company, on the one hand, and the several Underwriters, on the other hand, and the Company is capable of evaluating and understanding and understands and accepts the terms, risks and conditions of the transactions contemplated by this Agreement; (ii) in respect of each transaction contemplated hereby and the process leading to such transaction each Underwriter is and has been acting solely as a principal and is not the financial advisor, agent or fiduciary of the Company or its affiliates, shareholders, creditors or employees or any other party in respect of such transaction; (iii) no Underwriter has assumed or will assume an advisory, agency or fiduciary responsibility in favor of the Company with respect to any of the transactions contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company on other matters) and no Underwriter has any obligation to the Company with respect to the offering contemplated hereby except the obligations expressly set forth in this Agreement; (iv) the several Underwriters and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company and that the several Underwriters have no obligation to disclose any of such interests by virtue of any advisory, agency or fiduciary relationship in respect of any transaction contemplated hereby; and (v) the Underwriters have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby and the Company has consulted its own legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.

This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the several Underwriters, or any of them, with respect to the subject matter hereof.  The Company hereby waives and releases, to the fullest extent permitted

24

by law, any claims that the Company may have against the several Underwriters with respect to any breach or alleged breach of agency or fiduciary duty.

Section 13.  Research Analyst Independence

The Company acknowledges that the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Underwriters’ research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Company and/or the offering that differ from the views of their respective investment banking divisions.  The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advise communicated to the Company by such Underwriters’ investment banking divisions.  The Company acknowledges that each of the Underwriters is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the companies that may be the subject of the transactions contemplated by this Agreement.

Section 14.  Representations and Indemnities to Survive Delivery

The respective indemnities, contribution, agreements, representations, warranties and other statements of the Company, of its officers, and of the several Underwriters set forth in or made pursuant to this Agreement (i) will remain operative and in full force and effect, regardless of any (A) investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the officers or employees of any Underwriter, or any person controlling the Underwriter, the Company, the officers or employees of the Company, or any person controlling the Company, as the case may be, or (B) acceptance of the Securities and payment for them hereunder and (ii) will survive delivery of and payment for the Securities sold hereunder and any termination of this Agreement.

Re:          MGIC Investment Corporation (the “Company”)

Ladies and Gentlemen:

The undersigned is an owner of record or beneficially of certain shares of Common Stock of the Company (“Common Stock”).  The Company proposes to carry out a public offering of Common Stock (the “Offering”) for which you will act as the representatives of the underwriters.  The undersigned recognizes that the Offering will be of benefit to the undersigned and will benefit the Company.  The undersigned acknowledges that you and the other underwriters are relying on the representations and agreements of the undersigned contained in this letter in carrying out the Offering and in entering into underwriting arrangements with the Company with respect to the Offering.

In consideration of the foregoing, the undersigned hereby agrees that the undersigned will not, (and will cause any spouse or immediate family member of the spouse or the undersigned living in the undersigned’s household not to), without the prior written consent of Goldman, Sachs & Co. (“Goldman, Sachs”) (which consent may be withheld in its sole discretion), directly or indirectly, sell, offer, contract or grant any option to sell (including without limitation any short sale), pledge, transfer, establish an open “put equivalent position” or liquidate or decrease a “call equivalent position” within the meaning of Rule 16a-1(h) under the Securities Exchange Act of 1934, as amended, or otherwise dispose of or transfer (or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition of) including the filing (or participation in the filing of) of a registration statement with the Securities and Exchange Commission in respect of, any shares of Common Stock, options or warrants to acquire shares of Common Stock, or securities exchangeable or exercisable for or convertible into shares of Common Stock currently or hereafter owned either of record or beneficially (as defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended) by the undersigned (or such spouse or family member), or publicly announce an intention to do any of the foregoing, for a period commencing on the date hereof and continuing through the close of trading on the date 90 days after the date of the Prospectus (the “Lock-Up Period”).  The foregoing sentence shall not apply to the transfer of any or all of the shares of Common Stock owned by the undersigned, either during his lifetime or on death, by gift, will or intestate succession; provided, however, that in any such case it shall be a condition to such transfer that the transferee executes and delivers to Goldman, Sachs an agreement stating that the transferee is receiving and holding the Common Stock subject to the provisions of this letter agreement, and there shall be no further transfer of such Common Stock except in accordance with this letter.

In addition, the undersigned agrees that, without the prior written consent of Goldman, Sachs, it will not, during the Lock-Up Period, make any demand for or exercise any right with respect to, the registration of any shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock.

If (i) the Company issues an earnings release or material news, or a material event relating to the Company occurs, during the last 17 days of the lock-up period, or (ii) prior to the expiration of the lock-up period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the lock-up period, the restrictions imposed by this agreement shall continue to apply until the expiration of the 18-day period beginning on the date of the issuance of the earnings release or the occurrence of the material news or material event, unless Goldman, Sachs waives, in writing, such extension.  The undersigned hereby acknowledges that the Company has agreed in the Underwriting Agreement to provide written notice of any event that would result in an extension of the Lock-Up Period pursuant to the previous paragraph to the undersigned (in accordance with Section 15 of the Underwriting Agreement) and agrees that any such notice properly delivered will be deemed to have given to, and received by, the undersigned.  The undersigned hereby further agrees that, prior to engaging in any transaction or taking any other action that is subject to the terms of this Lock-Up Agreement during the period from the date of this Lock-Up Agreement to and including the 34th day following the expiration of the initial Lock-Up Period, it will give notice thereof to the Company and will not consummate such transaction or take any such action unless it has received written confirmation from the Company that the Lock-Up Period (as such may have been extended pursuant to the previous paragraph) has expired.  The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of shares of Common Stock or securities convertible into or exchangeable or exercisable for Common Stock held by the undersigned except in compliance with the foregoing restrictions.

This agreement is irrevocable and will be binding on the undersigned and the respective successors, heirs, personal representatives, and assigns of the undersigned.
