Such stockholder’s notice to the secretary shall set forth (a) as to each person whom the stockholder proposes to nominate for election or re-election as a director, (i) the name, age, business address and residence address of the person, (ii) the principal occupation or employment of the person, (iii) the class and number of shares of capital stock of the corporation which are directly or indirectly owned beneficially and/or of record by the person, (iv) a description of all direct and indirect compensation and other material monetary agreements, arrangements and understandings during the past three years, and any other material relationships (including any familial relationships), between or among the stockholder giving the notice and the beneficial owner, if any, on whose behalf the nomination is made, if any, and their respective affiliates and associates, or others acting in concert therewith, on the one hand, and each proposed nominee, and his or her respective affiliates and associates, or others acting in concert therewith, on the other hand, including, without limitation all information that would be required to be disclosed pursuant to Rule 404 promulgated under Regulation S-K if the stockholder making the nomination and any beneficial owner on whose behalf the nomination is made, if any, or any affiliate or associate thereof or person acting in concert therewith, were the “registrant” for purposes of such rule and the nominee were a director or executive officer of such registrant, and (v) any other information relating to the person that is required to be disclosed in a proxy statement or other filing required to be made in connection with solicitations of proxies for election of directors in a contested election pursuant to the rules and regulations promulgated under the Securities Exchange Act of 1934, as amended (including such person’s written consent to being named in the proxy statement as a nominee and to serving as a director if elected); (b) as to the stockholder giving the notice and the beneficial owner, if any, on whose behalf the nomination is made (i) their names and record addresses, (ii) the class and number of shares of capital stock of the corporation which are, directly or indirectly, owned beneficially and/or of record by each of them, (iii) any proxy, contract, arrangement, understanding, or relationship pursuant to which such stockholder or beneficial owner, if any, has a right to vote any security of the corporation; (c) a representation that the stockholder will appear in person or by proxy at the meeting to nominate the individual or individuals proposed in the notice; (d) with respect to each nominee for election or reelection to the board of directors, include a completed and signed representation and agreement required by Section 4.13(e) of these By-Laws; and (e) the information required in Section 3.06. The corporation may require any proposed nominee to furnish such other information as may reasonably be required by the corporation to determine the eligibility of such proposed nominee to serve as a director of the corporation or that could be material to a reasonable stockholder’s understanding of the independence, or lack thereof, of such nominee.

(d) The chairman of the meeting may, if the facts warrant, determine and declare to the meeting that any nomination made at the meeting was not made in accordance with the foregoing procedures and, in such event, the nomination shall be disregarded. Any decision by the chairman of the meeting shall be conclusive and binding upon all stockholders of the corporation for any purpose.

(e) To be eligible to be a nominee for election or reelection as a director of the corporation, a person must deliver (in accordance with the time periods prescribed for delivery of notice under this Section 4.13) to the secretary at the principal executive offices of the corporation a written questionnaire with respect to the background and qualification of such person and the background of any other person or entity on whose behalf the nomination is being made (which questionnaire shall be provided by the secretary upon written request) and a written representation and agreement (in the form provided by the secretary upon written request) that such person (A) is not and will not become a party to (1) any agreement, arrangement or understanding with, and has not given any commitment or assurance to, any person or entity as to how such person, if elected as a director of the corporation, will act or vote on any issue or question (a “Voting Commitment”) that has not been disclosed to the corporation or (2) any Voting Commitment that could limit or interfere with such person’s ability to comply, if elected as a director of the corporation, with such person’s fiduciary duties under applicable law, (B) is not and will not become a party to any agreement, arrangement or understanding with any person or entity other than the corporation with respect to any direct or indirect compensation, reimbursement or indemnification in connection with service or action as a director that has not been disclosed to the company and (C) in such person’s individual capacity and on behalf of any person or entity on whose behalf the nomination is being made, would be in compliance, if elected as a director of the corporation, and will comply with all applicable publicly disclosed corporate governance, conflict of interest, confidentiality and stock ownership and trading policies and guidelines of the corporation.

(f) Directors of the corporation shall be elected by the stockholders at an annual or special meeting of the stockholders, unless such election of directors is required by the terms of any series of preferred stock. If the number of nominees exceeds the number of directorships to be filled, the directors shall be elected by a plurality of the votes cast. If the number of nominees does not exceed the number of directors to be elected, a nominee shall be elected only if he or she receives a majority of the votes cast. If a nominee is an incumbent director who is standing for re-election and such nominee does not receive a majority of the votes cast in an election in which the number of nominees does not exceed the number of directors to be elected, the governance committee, or any other or successor committee responsible for the nomination of directors, must make a recommendation to the board on whether to accept the director’s resignation or whether other action should be taken, unless the director retires from the board before committee action or board action if there is no committee action. The board expects the director whose resignation is under consideration to abstain from participating in any decision regarding that resignation. The board will consider the committee’s recommendation and publicly disclose the board’s decision and the basis for that decision within 90 days from the date of certification of the final election results. However, if less than two members of the governance or successor committee are elected as directors at a meeting for the election of directors in an election in which the number of nominees does not exceed the number of directors to be elected, then the board shall consider and act upon the tendered resignation without a recommendation from the committee. The governance committee and the board may consider any factors that they deem relevant in deciding whether to accept a director’s resignation. Each share of the corporation entitled to be voted on the election of directors may only be voted noncumulatively. For purposes of this paragraph, a majority of the votes cast means that the number of shares voted “for” must exceed the number of shares voted “against” with respect to that director’s election (with “abstentions” and “broker non-votes” not counted as “for” or “against” that director’s election). If the number of nominees does not exceed the directors to be elected, each share of the corporation entitled to be voted on the election of directors may be voted for or against, or the person voting such share may abstain with respect to, each candidate for election. If directors are to be elected by a plurality of the votes cast, stockholders shall not be permitted to vote against a nominee.

(g) Each director who is nominated to stand for election shall, as a condition to such nomination, tender an irrevocable resignation in advance of the election of directors. Such resignation will be effective if, pursuant to Section 4.13(f) of these By-laws (a) the director does not receive a majority vote in the next election of directors in which the number of nominees does not exceed the number of directors to be elected, and (b) the board accepts the resignation, unless the director retires from the board before committee action or board action if there is no committee action. In addition, the board shall fill new director vacancies and new directorships only with candidates who agree to tender, promptly following their appointment by the board, the same form of irrevocable resignation.

SECTION 4.14. Voting of Stock . Unless otherwise ordered by the board of directors, each of the chairman of the board, the principal executive officer (as defined by the rules and regulations of the United States Securities and Exchange Commission) and the principal accounting officer (as defined by the rules and regulations of the United States Securities and Exchange Commission) shall have full power and authority, on behalf of the corporation, to attend and to act and vote, in person or by proxy, at any meeting of the stockholders of any company in which the corporation may hold stock, and at any such meeting shall possess and may exercise any and all of the rights and powers incident to the ownership of such stock which, as the owner thereof, the corporation might have possessed and exercised if present. The board of directors, by resolution adopted from time to time, may confer like powers upon any other person or persons.

SECTION 4.15. Endorsement of Securities for Transfer . Each of the chairman of the board, the principal executive officer and the principal accounting officer shall have the power to endorse and deliver for sale, assignment or transfer certificates for stock, bonds or other securities, registered in the name of or belonging to the corporation, whether issued by the corporation or by any other corporation, government, state or municipality or agency thereof; and the board of directors from time to time may confer like power upon any other officer, agent or person by resolution adopted from time to time. Every such endorsement shall be countersigned by the treasurer or an assistant treasurer.

SECTION 4.16. Lead Director . Unless the corporation shall have a non-executive Chairman of the Board, the directors will elect one of their numbers to serve as Lead Director. The Lead Director will assume such duties as the directors may designate from time to time.

Section 6.06.2 Transfer Restrictions.

(a) In order to preserve the Tax Benefits, from and after the Effective Date and before the Restriction Release Date, no Transfer other than to the corporation shall be permitted, and any such purported Transfer shall be null and void ab initio, as to the amount of any such purported Transfer of Corporation Securities that causes, after giving effect to such purported Transfer (or any series of Transfers of which such Transfer is a part), (i) any Person to become a Five Percent Shareholder or (ii) the Percentage Stock Ownership interest in the corporation of any Five Percent Shareholder to increase (a “Prohibited Transfer”). The prior sentence is not intended to prevent the Corporation Securities from being DTC–eligible and shall not preclude the settlement of any transactions in the Corporation Securities entered into through the facilities of a national securities exchange or any national securities quotation system, provided, that if the settlement of the transaction would result in a Prohibited Transfer, such Transfer shall nonetheless be a Prohibited Transfer.

(b) The restrictions contained in this Section 6.06 are for the purposes of reducing the risk that any “ownership change” (as defined in the Code) of the Corporation Securities may limit the corporation’s ability to utilize its Tax Benefits. In connection therewith, and to provide for effective policing of these provisions, a Restricted Holder who proposes to Acquire Corporation Securities shall, before the date of such proposed Acquisition, request in writing (a “Request”) that the board of directors of the corporation review such proposed Acquisition and authorize or not authorize such proposed Acquisition in accordance with this Section 6.06.2(b). A Request shall be made in accordance with this Section 6.06.2(b) and shall be delivered by fax and by registered mail, return receipt requested, to the secretary of the corporation at the principal executive offices of the corporation. Such Request shall be deemed to have been received by the corporation only when actually received by the corporation. To be made in accordance with this Section 6.06.2(b), a Request shall include (i) the name, address and telephone number of the Restricted Holder, (ii) a description of the Restricted Holder’s existing direct and indirect ownership of Corporation Securities, together with such ownership of all affiliates and associates of the Restricted Holder, (iii) a description of the Corporation Securities that the Restricted Holder proposes to Acquire, (iv) the date on which such proposed Acquisition is expected to take place (or, if such Acquisition is proposed to be made in a transaction on a national securities exchange or any national securities quotation system, a statement to that effect), (v) the name, address and telephone number of the proposed transferor of the Corporation Securities that the Restricted Holder proposes to Acquire (or, if such Acquisition is proposed to be made in a transaction on a national securities exchange or any national securities quotation system, a statement to that effect), (vi) a reasonably detailed description of the Acquisition, and (vii) a request that the board of directors authorize, if appropriate, such Acquisition pursuant to this Section 6.06.2(b). The board of directors may authorize an Acquisition by a Restricted Holder, if it determines in its sole discretion, that, such Acquisition will not be likely to directly or indirectly limit the availability to the corporation of the Tax Benefits or is otherwise in the best interests of the corporation and, in such case, the restrictions set forth in Section 6.06.2(a) shall not apply to such Acquisition. If the board of directors authorizes an Acquisition by a Restricted Holder, it may, in its sole discretion, deem such Restricted Holder to be an Existing Holder (and to determine the deemed Existing Holder Initial Ownership) under this Section 6.06. Any determination by the board of directors not to authorize a proposed Acquisition by a Restricted Holder shall cause such proposed Acquisition to be deemed a Prohibited Transfer. Any determination to authorize a proposed Acquisition by a Restricted Holder granted hereunder may be granted in whole or in part, and may be subject to any limitations or conditions (including restrictions on the ability of the Restricted Holder to subsequently transfer Corporation Securities acquired through such authorized Acquisition), in each case as and to the extent the board shall determine in its sole discretion. In addition, the board of directors may, in its sole discretion, require representations from the Restricted Holder or an opinion of counsel to be rendered by counsel selected by the board of directors, that the Transfer will not result in the application of any Section 382 limitation on the use of the Tax Benefits or other matters that the board of directors may determine. Any Restricted Holder who makes a Request to the board of directors shall reimburse the corporation, on demand, for all costs and expenses incurred by the corporation with respect to any proposed Acquisition of Corporation Securities, including the corporation’s costs and expenses incurred in determining whether to authorize the proposed Acquisition, which costs may include any expenses of counsel and/or tax advisors engaged by the board of directors to advise the board of directors or deliver an opinion thereto.

Section 6.06.3 Treatment of Excess Securities.

(a) No employee or agent of the corporation shall record any Prohibited Transfer, and the purported transferee of a Prohibited Transfer (the “Purported Transferee”) shall not be recognized as a stockholder of the corporation for any

- 16 -

purpose whatsoever in respect of the Corporation Securities that are the subject of the Prohibited Transfer (the “Excess Securities”). The Purported Transferee shall not be entitled with respect to such Excess Securities to any rights of a stockholder of the corporation, including the right to vote such Excess Securities and to receive dividends or distributions, whether liquidating or otherwise, in respect thereof. Once the Excess Securities have been acquired in a Transfer that is not a Prohibited Transfer, such Corporation Securities shall cease to be Excess Securities.

(b) If the board of directors determines that a Prohibited Transfer has been recorded by an agent or employee of the corporation notwithstanding the prohibition in Section 6.06.3(a), such recording and the Prohibited Transfer shall be null and void ab initio and have no legal effect and, upon written demand by the corporation, the Purported Transferee shall transfer or cause to be transferred any certificate or other evidence of ownership of the Excess Securities within the Purported Transferee’s possession or control, together with any dividends or other distributions that were received by the Purported Transferee from the corporation with respect to the Excess Securities (the “Prohibited Distributions”), to an agent designated by the board of directors (the “Agent”). In the event of an attempted Prohibited Transfer involving the purchase or Acquisition of Corporation Securities in violation of this Section 6.06 by a Restricted Holder, the Agent shall thereupon sell to a buyer or buyers, which may include the corporation or the purported transferor, the Excess Securities transferred to it in one or more arm’s–length transactions (including over a national securities exchange or national securities quotation system on which the Corporation Securities may be traded); provided, however, that the Agent, in its sole discretion, shall effect such sale or sales in an orderly fashion and shall not be required to effect any such sale within any specific time frame if the Agent determines such sale or sales could disrupt the market for the Corporation Securities, could adversely affect the value of the Corporation Securities or may be in violation of applicable securities laws. If the Purported Transferee has resold the Excess Securities before receiving the corporation’s demand to surrender the Excess Securities to the Agent, the Purported Transferee shall be deemed to have sold the Excess Securities for the Agent, and shall be required to transfer to the Agent any Prohibited Distributions and proceeds of such sale, unless the corporation grants written permission to the Purported Transferee to retain a portion of such sales proceeds not exceeding the amount that the Purported Transferee would have received from the Agent pursuant to Section 6.06.3(c) if the Agent, rather than the Purported Transferee, had resold the Excess Securities.

(c) The Agent shall apply any proceeds of a sale by it of Excess Securities and, if the Purported Transferee had previously resold the Excess Securities, any amounts received by it from a Purported Transferee, as follows: (i) first, to reimburse itself to the extent necessary to cover its costs and expenses incurred in accordance with its duties hereunder; (ii) second, to reimburse the Purported Transferee for the amounts paid by the Purported Transferee for the Excess Securities (or in the case of any Prohibited Transfer by gift, devise or inheritance or any other Prohibited Transfer without consideration, the fair market value, calculated on the basis of the closing market price for the Corporation Securities on the day before the Prohibited Transfer), and (iii) third, the remainder, if any, to the original transferor, or, if the original transferor cannot be readily identified, to an entity designated by the corporation’s board of directors that is described in Section 501(c) of the Code, contributions to which must be eligible for deduction under each of Sections 170(b)(1)(A), 2055 and 2522 of the Code. The recourse of any Purported Transferee with respect to any Prohibited Transfer shall be limited to the amount payable to the Purported Transferee pursuant to clause (ii) of this Section 6.06.3(c). Except as may be required by law, in no event shall the proceeds of any sale of Excess Securities pursuant to this Section 6.06 inure to the benefit of the corporation or the Agent, except to the extent used to cover expenses incurred by the Agent in performing its duties hereunder.

(d) In the event of any Transfer to the corporation, or any Transfer that does not involve a transfer of securities of the corporation within the meaning of Delaware law (“Securities,” and individually, a “Security”), that would in either case cause (i) any Person to become a Five Percent Shareholder or (ii) the Percentage Stock Ownership interest of any Five Percent Shareholder to increase, the application of Section 6.06.3(b) and Section 6.06.3(c) shall be modified as described in this Section 6.06.3(d). In such case, no such Five Percent Shareholder shall be required to dispose of any interest that is not a Security, but such Five Percent Shareholder and/or any Person whose ownership of Securities is attributed to such Five Percent Shareholder shall be deemed to have disposed of and shall be required to dispose of sufficient Securities (which Securities shall be disposed of in the inverse order in which they were acquired) to cause such Five Percent Shareholder, after such disposition, not to be in violation of this Section 6.06. Such disposition shall be deemed to occur simultaneously with the Transfer giving rise to the application of this provision, and such number of Securities that are deemed to be disposed of shall be considered Excess Securities and shall be disposed of through the Agent as provided in Section 6.06.3(b) and Section 6.06.3(c), except that the maximum aggregate amount payable either to such Five Percent Shareholder, or to such other Person that was the direct holder of such Excess Securities, in connection with such sale shall be the fair market value of

- 17 -

such Excess Securities at the time of the purported Transfer. All expenses incurred by the Agent in disposing of such Excess Securities shall be paid out of any amounts due such Five Percent Shareholder or such other Person. The purpose of this Section 6.06.3(d) is to extend the restrictions in Section 6.06.2(a) and Section 6.06.3(a) to situations in which there is a Five Percent Shareholder without a direct Transfer of Securities, and this Section 6.06.3(d), along with the other provisions, shall be interpreted to produce the same results, with differences as the context requires, as a direct Transfer of Corporation Securities.

(e) If the Purported Transferee fails to surrender the Excess Securities or the proceeds of a sale thereof to the Agent within thirty (30) days from the date on which the corporation makes a demand pursuant to Section 6.06.3(b) or any written demand with respect to a deemed disposition pursuant to Section 6.06.3(d), then the corporation may take any actions it deems necessary to enforce the provisions hereof, including the institution of legal proceedings to compel such surrender.

(f) If any Person shall knowingly violate, or knowingly cause any other Person under control of such Person (a “Controlled Person”) to violate this Section 6.06 (including failure to surrender the Excess Securities or the proceeds of a sale thereof as demanded by the corporation pursuant to Section 6.06.3(e)), then that Person and any Controlled Person shall be jointly and severally liable to the corporation for, and shall indemnify and hold the corporation harmless against, any and all losses and damages suffered as a result of such violation, including any attorneys’ and auditors’ fees incurred in connection with such violation.

Section 6.06.4 Legends; Compliance.

(a) All certificates reflecting Corporation Securities issued on or after the Effective Date shall, until the Restriction Release Date, bear a conspicuous legend in substantially the following form:

THE TRANSFER OF SECURITIES REPRESENTED HEREBY IS SUBJECT TO RESTRICTION PURSUANT TO SECTION 6.06 OF THE AMENDED AND RESTATED BYLAWS OF RADIAN GROUP INC. A COPY OF WHICH MAY BE OBTAINED UPON WRITTEN REQUEST TO THE CORPORATION AT ITS PRINCIPAL PLACE OF BUSINESS. IF THE TRANSFER RESTRICTIONS ARE VIOLATED, THEN THE TRANSFER WILL BE VOID AND THE PURPORTED TRANSFEREE OF THE STOCK WILL BE REQUIRED TO TRANSFER THE EXCESS SECURITIES (AS DEFINED IN THE AMENDED AND RESTATED CERTIFICATE OF INCORPORATION AND THE AMENDED AND RESTATED BYLAWS) TO THE CORPORATION’S AGENT.
