The Company must promptly notify the Rights Agent of a Distribution Date and request its transfer agent to give the Rights Agent a shareholder list together with all other relevant information. As soon as practicable after the Rights Agent is notified of the Distribution Date and receives such information, the Rights Agent will send by first-class, insured, postage prepaid mail, to each record holder of the Common Shares as of the Close of Business on the Distribution Date, at the address of such holder shown on the records of the Company, one or more Rights certificates, in substantially the form of Exhibit B hereto (the “Rights Certificates”), evidencing one Right for each Common Share so held, subject to adjustment as provided herein. In the event that any adjustment in the number of Rights per Common Share has been made pursuant to Section 11, at the time of distribution of the Rights Certificates, the Company shall make the necessary and appropriate rounding adjustments (in accordance with Section 14(a)) so that Rights Certificates representing only whole numbers of Rights are distributed and cash is paid in lieu of any fractional Rights. As of and after the Distribution Date, the Rights will be evidenced solely by such Rights Certificates.

(b) The Company will make available, as promptly as practicable following the Record Date, a copy of a Summary of Rights, in substantially the form attached hereto as Exhibit C (the “Summary of Rights”), to any holder of Rights who may so request from time to time prior to the Expiration Date. With respect to certificates for the Common Shares outstanding as

7

of the Record Date, or issued subsequent to the Record Date, until the Distribution Date, the Rights will be evidenced by such certificates registered in the names of the holders thereof. Until the earlier of the Distribution Date or the Expiration Date, the surrender for transfer of any certificate representing Common Shares in respect of which Rights have been issued shall also constitute the transfer of the Rights associated with such Common Shares.

(c) Rights shall be issued in respect of all Common Shares which are issued (whether originally issued or from the Company’s treasury) after the Record Date but prior to the earlier of the Distribution Date or the Expiration Date or, in certain circumstances provided in Section 22, after the Distribution Date. Certificates representing such Common Shares shall also be deemed to be certificates for Rights, and shall bear a legend substantially in the following form:

This certificate also evidences and entitles the holder hereof to certain Rights as set forth in the Amended and Restated Section 382 Rights Agreement between PulteGroup, Inc. (the “Company”) and Computershare Trust Company, N.A. (the “Rights Agent”) dated as of March 5, 2009, as the same may be amended from time to time (the “Rights Agreement”), the terms of which are hereby incorporated herein by reference and a copy of which is on file at the principal offices of the Company. Under certain circumstances, as set forth in the Rights Agreement, such Rights will be evidenced by separate certificates and will no longer be evidenced by this certificate. The Company will mail to the holder of this certificate a copy of the Rights Agreement, as in effect on the date of mailing, without charge promptly after receipt of a written request therefor. Under certain circumstances set forth in the Rights Agreement, Rights issued to, or held by, any Person who is, was or becomes an Acquiring Person (as defined in the Rights Agreement), whether currently held by or on behalf of such Person or by any subsequent holder, may become null and void.

With respect to such certificates containing the foregoing legend, until the earlier of (i) the Distribution Date or (ii) the Expiration Date, the Rights associated with the Common Shares represented by such certificates shall be evidenced by such certificates alone and registered holders of Common Shares shall also be the registered holders of the associated Rights, and the transfer of any of such certificates shall also constitute the transfer of the Rights associated with the Common Shares represented by such certificates. In the event the Company purchases or acquires any of its Common Shares after the Record Date but prior to the Distribution Date, any Rights associated with such shares shall be deemed cancelled and retired so that the Company shall not be entitled to exercise any Rights associated with Common Shares that are not outstanding.

Section 4. Form of Rights Certificates .

(a) The Rights Certificates (and the forms of election to purchase and of assignment to be printed on the reverse thereof) shall each be substantially in the form set forth in Exhibit B hereto and may have such marks of identification or designation and such legends, summaries or endorsements printed thereon as the Company may deem appropriate and as are

8

not inconsistent with the provisions of this Agreement, or as may be required to comply with any applicable law or with any rule or regulation made pursuant thereto or with any rule or regulation of any stock exchange on which the Rights may from time to time be listed, or to conform to usage. Subject to the provisions of Section 11 and Section 22, the Rights Certificates, whenever distributed, shall be dated as of the Record Date or, in the case of Rights with respect to Common Shares issued or becoming outstanding after the Record Date, the same date as the date of the share certificate evidencing such shares, and on their face shall entitle the holders thereof to purchase such number of one one-thousandths of a Preferred Share as shall be set forth therein at the price set forth therein (such exercise price per one one-thousandth of a share, the “Purchase Price”), but the amount and type of securities purchasable upon the exercise of each Right and the Purchase Price thereof shall be subject to adjustment from time to time as provided in Section 11.

(b) Any Rights Certificate issued pursuant to Section 3(a), Section 11(a)(ii) or Section 22 that represents Rights beneficially owned by any Person known to be: (i) an Acquiring Person, (ii) a transferee of an Acquiring Person who becomes a transferee after the Acquiring Person becomes such, or (iii) a transferee of an Acquiring Person who becomes a transferee prior to or concurrently with the Acquiring Person becoming such and receives such Rights pursuant to either (A) a transfer (whether or not for consideration) from the Acquiring Person to holders of equity interests in such Acquiring Person or to any Person with whom such Acquiring Person has any continuing plan, agreement, arrangement or understanding regarding the transferred Rights, shares of Corporation Securities or the Company or (B) a transfer which the Board of Directors of the Company has determined is part of a plan, agreement, arrangement or understanding which has as a primary purpose or effect avoidance of Section 7(e), and any Rights Certificate issued pursuant to Section 6 or Section 11 upon transfer, exchange, replacement or adjustment of any other Rights Certificate referred to in this sentence, shall contain (to the extent feasible) the following legend:

The Rights represented by this Rights Certificate are or were beneficially owned by a Person who was or became an Acquiring Person (as defined in the Rights Agreement). Accordingly, this Rights Certificate and the Rights represented hereby may become null and void in the circumstances specified in Section 7(e) of such Agreement.

The absence of the foregoing legend on any Rights Certificate shall in no way affect any of the other provisions of this Agreement, including, without limitation, the provisions of Section 7(e).

Section 5. Countersignature and Registration .

(a) The Rights Certificates shall be executed on behalf of the Company by its Chairman of the Board, its President or any Vice President, either manually or by facsimile signature, and shall have affixed thereto the Company’s seal or a facsimile thereof which shall be attested by the Secretary or an Assistant Secretary of the Company, either manually or by facsimile signature. The Rights Certificates shall be countersigned manually or by facsimile signature by the Rights Agent and shall not be valid for any purpose unless so countersigned. In

9

case any officer of the Company who shall have signed any of the Rights Certificates shall cease to be such officer of the Company before countersignature by the Rights Agent and issuance and delivery by the Company, such Rights Certificates, nevertheless, may be countersigned by the Rights Agent and issued and delivered by the Company with the same force and effect as though the person who signed such Rights Certificates had not ceased to be such officer of the Company; and any Rights Certificates may be signed on behalf of the Company by any person who, at the actual date of the execution of such Rights Certificate, shall be a proper officer of the Company to sign such Rights Certificate, although at the date of the execution of this Rights Agreement any such person was not such an officer.

(b) Following the Distribution Date, the Rights Agent will keep or cause to be kept, at its principal office or offices designated as the appropriate place for surrender of Rights Certificates upon exercise or transfer, books for registration and transfer of the Rights Certificates issued hereunder. Such books shall show the names and addresses of the respective holders of the Rights Certificates, the number of Rights evidenced on its face by each of the Rights Certificates and the certificate number and the date of each of the Rights Certificates.

Any registered holder desiring to transfer, split up, combine or exchange any Rights Certificate or Certificates shall make such request in writing delivered to the Rights Agent, and shall surrender the Rights Certificate or Certificates to be transferred, split up, combined or exchanged at the principal office or offices of the Rights Agent designated for such purpose. Neither the Rights Agent nor the Company shall be obligated to take any action whatsoever with respect to the transfer of any such surrendered Rights Certificate until the registered holder shall have completed and signed the certificate contained in the form of assignment on the reverse side of such Rights Certificate and shall have provided such additional evidence of the identity of the Beneficial Owner (or former Beneficial Owner) or Affiliates or Associates thereof as the Company or the Rights Agent shall reasonably request. Thereupon the Rights Agent shall, subject to Section 4(b), Section 7(e), Section 11, Section 14 and Section 24, countersign and deliver to the Person entitled thereto a Rights Certificate or Rights Certificates, as the case may be, as so requested. The Company may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any transfer, split up, combination or exchange of Rights Certificates.

(b) Upon receipt by the Company and the Rights Agent of evidence reasonably satisfactory to them of the loss, theft, destruction or mutilation of a Rights Certificate, and, in

10

case of loss, theft or destruction, of indemnity or security satisfactory to them, and reimbursement to the Company and the Rights Agent of all reasonable expenses incidental thereto, and upon surrender to the Rights Agent and cancellation of the Rights Certificates if mutilated, the Company will execute and deliver a new Rights Certificate of like tenor to the Rights Agent for countersignature and delivery to the registered owner in lieu of the Rights Certificate so lost, stolen, destroyed or mutilated.

direct the depositary agent to comply with such request, (ii) requisition from the Company the amount of cash, if any, to be paid in lieu of fractional shares in accordance with Section 14, (iii) after receipt of such certificates or depositary receipts, cause the same to be delivered to or upon the order of the registered holder of such Rights Certificate, registered in such name or names as may be designated by such holder, and (iv) after receipt thereof, deliver such cash, if any, to or upon the order of the registered holder of such Rights Certificate. The payment of the Purchase Price (as such amount may be reduced pursuant to Section 11(a)(iii)) shall be made in cash or by certified bank check or bank draft payable to the order of the Company. In the event that the Company is obligated to issue other securities (including, without limitation, Common Shares) of the Company, pay cash and/or distribute other property pursuant to Section 11(a), the Company will make all arrangements necessary so that such other securities, cash and/or other property are available for distribution by the Rights Agent, if and when necessary to comply with the terms of this Agreement. The Company reserves the right to require prior to the occurrence of a Section 11(a)(ii) Event that, upon any exercise of Rights, a number of Rights be exercised so that only whole Preferred Shares would be issued.

(d) In case the registered holder of any Rights Certificate shall exercise less than all the Rights evidenced thereby, a new Rights Certificate evidencing Rights equivalent to the Rights remaining unexercised shall be issued by the Rights Agent and delivered to, or upon the order of, the registered holder of such Rights Certificate, registered in such name or names as may be designated by such holder, subject to the provisions of Section 14.

(e) Notwithstanding anything in this Agreement to the contrary, from and after the first occurrence of a Section 11(a)(ii) Event, any Rights beneficially owned by (i) an Acquiring Person, (ii) a transferee of an Acquiring Person who becomes a transferee after the Acquiring Person becomes such, (iii) a transferee of an Acquiring Person who becomes a transferee prior to or concurrently with the Acquiring Person becoming such and receives such Rights pursuant to either (A) a transfer (whether or not for consideration) from the Acquiring Person to holders of equity interests in such Acquiring Person or to any Person with whom the Acquiring Person has any continuing plan, agreement, arrangement or understanding regarding the transferred Rights, shares of Corporation Securities or the Company or (B) a transfer which the Board of Directors of the Company has determined is part of a plan, agreement, arrangement or understanding which has as a primary purpose or effect the avoidance of this Section 7(e) and (iv) subsequent transferees of such Persons described in clause (i), (ii) or (iii) of this sentence shall become null and void without any further action, and no holder of such Rights shall have any rights whatsoever with respect to such Rights, whether under any provision of this Agreement or otherwise. The Company shall notify the Rights Agent when this Section 7(e) applies and shall use all reasonable efforts to ensure that the provisions of this Section 7(e) and Section 4(b) are complied with, but neither the Company nor the Rights Agent shall have any liability to any holder of Rights Certificates or other Person as a result of the Company’s failure to make any determinations with respect to an Acquiring Person or any of its transferees hereunder.

(f) Notwithstanding anything in this Agreement to the contrary, neither the Rights Agent nor the Company shall be obligated to undertake any action with respect to a registered holder upon the occurrence of any purported exercise as set forth in this Section 7

12

unless such registered holder shall have (i) properly completed and signed the certificate contained in the form of election to purchase set forth on the reverse side of the Rights Certificate surrendered for such exercise and (ii) provided such additional evidence of the identity of the Beneficial Owner (or former Beneficial Owner) or Affiliates or Associates thereof as the Company or the Rights Agent shall reasonably request.

Section 8. Cancellation and Destruction of Rights Certificates . All Rights Certificates surrendered for the purpose of exercise, transfer, split up, combination or exchange shall, if surrendered to the Company or any of its agents, be delivered to the Rights Agent for cancellation or in cancelled form, or, if surrendered to the Rights Agent, shall be cancelled by it, and no Rights Certificates shall be issued in lieu thereof, except as expressly permitted by any of the provisions of this Agreement. The Company shall deliver to the Rights Agent for cancellation and retirement, and the Rights Agent shall so cancel and retire, any other Rights Certificates purchased or acquired by the Company otherwise than upon the exercise thereof. The Rights Agent shall deliver all cancelled Rights Certificates to the Company, or shall, at the written request of the Company, destroy such cancelled Rights Certificates, and in such case shall deliver a certificate of destruction thereof to the Company.

Section 9. Reservation and Availability of Capital Shares . (a) The Company covenants and agrees that it will cause to be reserved and kept available out of its authorized and unissued Preferred Shares (and, following the occurrence of a Section 11(a)(ii) Event, out of its authorized and unissued Common Shares and/or other securities or out of its authorized and issued shares held in its treasury), the number of Preferred Shares (and, following the occurrence of a Section 11(a)(ii) Event, Common Shares and/or other securities) that, as provided in this Agreement, including, without limitation, Section 11(a)(iii), will be sufficient to permit the exercise in full of all outstanding Rights.

(b) So long as the Preferred Shares (and, following the occurrence of a Section 11(a)(ii) Event, Common Shares and/or other securities) issuable and deliverable upon the exercise of the Rights may be listed on any national securities exchange, the Company shall use its best efforts to cause, from and after such time as the Rights become exercisable, all shares reserved for such issuance to be listed on such exchange, upon official notice of issuance upon such exercise.

(c) The Company shall use its best efforts to (i) prepare and file, as soon as practicable following the earliest date after the first occurrence of a Section 11(a)(ii) Event on which the consideration to be delivered by the Company upon exercise of the Rights has been determined in accordance with Section 11(a)(iii), a registration statement under the Act with respect to the securities purchasable upon exercise of the Rights on an appropriate form, (ii) cause such registration statement to become effective as soon as practicable after such filing, and (iii) cause such registration statement to remain effective (with a prospectus at all times meeting the requirements of the Act) until the earlier of (A) the date as of which the Rights are no longer exercisable for such securities, and (B) the Expiration Date. The Company will also take such action as may be appropriate under, or to ensure compliance with, the securities or “blue sky” laws of the various states in connection with the exercisability of the Rights. The Company may temporarily suspend, for a period of time not to exceed ninety (90) days after the date set forth in

13

clause (i) of the first sentence of this Section 9(c), the exercisability of the Rights in order to prepare and file such registration statement and permit it to become effective. Upon any such suspension, the Company shall issue a public announcement stating that the exercisability of the Rights has been temporarily suspended, as well as a public announcement at such time as the suspension is no longer in effect. In addition, if the Company shall determine that filing a registration statement is required under the Act or any securities laws following the Distribution Date, and a Section 11(a)(ii) Event has not occurred, the Company may temporarily suspend (and shall give the Rights Agent prompt notice thereof) the exercisability of Rights until such time as a registration statement has been declared effective, and, upon any such suspension, the Company shall issue a public announcement stating that the exercisability of the Rights has been temporarily suspended, as well as a public announcement at such time as the suspension is no longer in effect. Notwithstanding any provision of this Agreement to the contrary, the Rights shall not be exercisable in any jurisdiction if the requisite qualification or exemption in such jurisdiction shall not have been obtained, the exercise thereof shall not be permitted under applicable law or a registration statement shall not have been declared effective.

(d) The Company covenants and agrees that it will take all such actions as may be necessary to ensure that all one one-thousandths of a Preferred Share (and, following the occurrence of a Section 11(a)(ii) Event, Common Shares and/or other securities) delivered upon exercise of Rights shall, at the time of delivery of the certificates for such shares (subject to payment of the Purchase Price), be duly and validly authorized and issued and fully paid and nonassessable.

(e) The Company further covenants and agrees that it will pay, when due and payable, any and all transfer taxes and governmental charges which may be payable in respect of the issuance or delivery of the Rights Certificates and of any certificates for a number of one one-thousandths of a Preferred Share (or Common Shares and/or other securities, as the case may be) upon the exercise of Rights. The Company shall not, however, be required to pay any transfer tax which may be payable in respect of any transfer or delivery of Rights Certificates to a Person other than, or the issuance or delivery of a number of one one-thousandths of a Preferred Share (or Common Shares and/or other securities, as the case may be) in respect of a name other than that of, the registered holder of the Rights Certificates evidencing Rights surrendered for exercise or to issue or deliver any certificates for a number of one one-thousandths of a Preferred Share (or Common Shares and/or other securities, as the case may be) in a name other than that of the registered holder upon the exercise of any Rights until such tax shall have been paid (any such tax being payable by the holder of such Rights Certificate at the time of surrender) or until it has been established to the Company’s satisfaction that no such tax is due.

Section 10. Preferred Shares Record Date . Each Person in whose name any certificate for a number of one one-thousandths of a Preferred Share (or Common Shares and/or other securities, as the case may be) is issued upon the exercise of Rights shall for all purposes be deemed to have become the holder of record of such fractional Preferred Shares (or Common Shares and/or other securities, as the case may be) represented thereby on, and such certificate shall be dated, the date upon which the Rights Certificate evidencing such Rights was duly surrendered and payment of the Purchase Price (and all applicable transfer taxes) was made;

14

provided , however , that if the date of such surrender and payment is a date upon which the Preferred Shares (or Common Shares and/or other securities, as the case may be) transfer books of the Company are closed, such Person shall be deemed to have become the record holder of such shares (fractional or otherwise) on, and such certificate shall be dated, the next succeeding Business Day on which the Preferred Shares (or Common Shares and/or other securities, as the case may be) transfer books of the Company are open. Prior to the exercise of the Rights evidenced thereby, the holder of a Rights Certificate shall not be entitled to any rights of a shareholder of the Company with respect to shares or other securities for which the Rights shall be exercisable, including, without limitation, the right to vote, to receive dividends or other distributions or to exercise any preemptive rights, and shall not be entitled to receive any notice of any proceedings of the Company, except as provided herein.

Section 11. Adjustment of Purchase Price, Number and Kind of Shares or Number of Rights . The Purchase Price, the number and kind of shares covered by each Right and the number of Rights outstanding are subject to adjustment from time to time as provided in this Section 11.

(a) (i) In the event the Company shall at any time after the date of this Agreement (A) declare a dividend on the Preferred Shares payable in Preferred Shares, (B) subdivide the outstanding Preferred Shares, (C) combine the outstanding Preferred Shares into a smaller number of shares, or (D) issue any shares of its capital shares in a reclassification of the Preferred Shares (including, without limitation, any such reclassification in connection with a consolidation or merger in which the Company is the continuing or surviving corporation), except as otherwise provided in this Section 11(a) and Section 7(e), the Purchase Price in effect at the time of the record date for such dividend or of the effective date of such subdivision, combination or reclassification, and the number and kind of Preferred Shares or capital shares, as the case may be, issuable on such date, shall be proportionately adjusted so that the holder of any Right exercised after such time shall be entitled to receive, upon payment of the Purchase Price then in effect, the aggregate number and kind of Preferred Shares or capital shares, as the case may be, which, if such Right had been exercised immediately prior to such date and at a time when the Preferred Shares transfer books of the Company were open, such holder would have owned upon such exercise and been entitled to receive by virtue of such dividend, subdivision, combination or reclassification. If an event occurs which would require an adjustment under both this Section 11(a)(i) and Section 11(a)(ii), the adjustment provided for in this Section 11(a)(i) shall be in addition to, and shall be made prior to, any adjustment required pursuant to Section 11(a)(ii).

(ii) Subject to Section 24, in the event any Person becomes an Acquiring Person, then each holder of a Right (except as provided below and in Section 7(e)) shall thereafter have the right to receive, upon exercise thereof at a price equal to the then current Purchase Price in accordance with the terms of this Agreement, in lieu of a number of one one-thousandths of a Preferred Share, such number of Common Shares of the Company as shall equal the result obtained by (x) multiplying the then current Purchase Price by the then number of one one-thousandths of a Preferred Share for which a Right was exercisable immediately

15

prior to the first occurrence of a Section 11(a)(ii) Event and (y) dividing that product (which, following such first occurrence shall thereafter be referred to as the “Purchase Price” for each Right and for all purposes of this Agreement) by 50% of the current market price (determined pursuant to Section 11(d)) per Common Share on the date of such first occurrence (such number of shares, the “Adjustment Shares”).

(iii) In the event that the number of Common Shares which are authorized by the Company’s articles of incorporation, as amended, but not outstanding or reserved for issuance for purposes other than upon exercise of the Rights, is not sufficient to permit the exercise in full of the Rights in accordance with the foregoing subparagraph (ii) of this Section 11(a), the Company shall: (A) determine the value of the Adjustment Shares issuable upon the exercise of a Right (the “Current Value”), and (B) with respect to each Right, make adequate provision to substitute for the Adjustment Shares, upon the exercise of a Right and payment of the applicable Purchase Price, (1) cash, (2) a reduction in the Purchase Price, (3) Common Shares or other equity securities of the Company (including, without limitation, preferred shares or units of preferred shares, such as the Preferred Shares, which the Board of Directors of the Company has deemed to have substantially the same value or economic rights as Common Shares (such preferred shares or units of preferred shares, “common share equivalents”)), (4) debt securities of the Company, (5) other assets, or (6) any combination of the foregoing, having an aggregate value equal to the Current Value (less the amount of any reduction in the Purchase Price), where such aggregate value has been determined by the Board of Directors of the Company based upon the advice of a nationally recognized investment banking firm selected by the Board of Directors of the Company; provided , however , if the Company shall not have made adequate provision to deliver value pursuant to clause (B) above within thirty (30) days following the later of (x) the first occurrence of a Section 11(a)(ii) Event and (y) the date on which the Company’s right of redemption pursuant to Section 23(a) expires (the later of (x) and (y) being referred to herein as the “Section 11(a)(ii) Trigger Date”), then the Company shall be obligated to deliver, upon the surrender for exercise of a Right and without requiring payment of the Purchase Price, Common Shares (to the extent available) and then, if necessary, cash, which shares and/or cash have an aggregate value equal to the Spread. For purposes of the preceding sentence, the term “Spread” shall mean the excess of (i) the Current Value over (ii) the Purchase Price. If the Board of Directors of the Company shall determine in good faith that it is likely that sufficient additional Common Shares could be authorized for issuance upon exercise in full of the Rights, the thirty (30) day period set forth above may be extended to the extent necessary, but not more than ninety (90) days after the Section 11(a)(ii) Trigger Date, in order that the Company may seek shareholder approval for the authorization of such additional shares (such thirty (30) day period, as it may be extended, the “Substitution Period”). To the extent the Company determines that action should be taken pursuant to the first and/or third sentences of this Section 11(a)(iii), the Company (x) shall provide, subject to Section 7(e), that such action

16

shall apply uniformly to all outstanding Rights, and (y) may suspend the exercisability of the Rights until the expiration of the Substitution Period in order to seek such shareholder approval for such authorization of additional shares and/or to decide the appropriate form of distribution to be made pursuant to such first sentence and to determine the value thereof. In the event of any such suspension, the Company shall issue a public announcement stating that the exercisability of the Rights has been temporarily suspended, as well as a public announcement at such time as the suspension is no longer in effect (with prompt notice of such announcements to the Rights Agent). For purposes of this Section 11(a)(iii), the value of each Adjustment Share shall be the current market price (as determined pursuant to Section 11(d)) per Common Share on the Section 11(a)(ii) Trigger Date and the value of any “common share equivalent” shall be deemed to equal the current market price (as determined pursuant to Section 11(d)) per Common Share on such date.

(b) In case the Company shall fix a record date for the issuance of rights (other than the Rights), options or warrants to all holders of Preferred Shares entitling them to subscribe for or purchase (for a period expiring within forty-five (45) calendar days after such record date) Preferred Shares (or shares having the same rights, privileges and preferences as the Preferred Shares (“equivalent preferred shares”)) or securities convertible into Preferred Shares or equivalent preferred shares at a price per Preferred Share or per share of equivalent preferred shares (or having a conversion price per share, if a security convertible into Preferred Shares or equivalent preferred shares) less than the current market price (as determined pursuant to Section 11(d)) per Preferred Share on such record date, the Purchase Price to be in effect after such record date shall be determined by multiplying the Purchase Price in effect immediately prior to such record date by a fraction, the numerator of which shall be the number of Preferred Shares outstanding on such record date, plus the number of Preferred Shares which the aggregate offering price of the total number of Preferred Shares and/or equivalent preferred shares so to be offered (and/or the aggregate initial conversion price of the convertible securities so to be offered) would purchase at such current market price, and the denominator of which shall be the number of Preferred Shares outstanding on such record date, plus the number of additional Preferred Shares and/or equivalent preferred shares to be offered for subscription or purchase (or into which the convertible securities so to be offered are initially convertible). In case such subscription price may be paid by delivery of consideration part or all of which may be in a form other than cash, the value of such consideration shall be as determined in good faith by the Board of Directors of the Company, whose determination shall be described in a statement filed with the Rights Agent and shall be binding on the Rights Agent and the holders of the Rights. Preferred Shares owned by or held for the account of the Company shall not be deemed outstanding for the purpose of any such computation. Such adjustment shall be made successively whenever such a record date is fixed, and in the event that such rights, options or warrants are not so issued, the Purchase Price shall be adjusted to be the Purchase Price which would then be in effect if such record date had not been fixed.

(c) In case the Company shall fix a record date for a distribution to all holders of Preferred Shares (including, without limitation, any such distribution made in connection with a consolidation or merger in which the Company is the continuing corporation) of evidences of

17

indebtedness, cash (other than a regular periodic cash dividend out of the earnings or retained earnings of the Company), assets (other than a dividend payable in Preferred Shares, but including, without limitation, any dividend payable in shares other than Preferred Shares) or subscription rights or warrants (excluding those referred to in Section 11(b)), the Purchase Price to be in effect after such record date shall be determined by multiplying the Purchase Price in effect immediately prior to such record date by a fraction, the numerator of which shall be the current market price (as determined pursuant to Section 11(d)) per Preferred Share on such record date, less the fair market value (as determined in good faith by the Board of Directors of the Company, whose determination shall be described in a statement filed with the Rights Agent and shall be binding on the Rights Agent and the holders of the Rights) of the portion of the cash, assets or evidences of indebtedness so to be distributed or of such subscription rights or warrants applicable to a Preferred Share and the denominator of which shall be such current market price (as determined pursuant to Section 11(d)) per Preferred Share. Such adjustments shall be made successively whenever such a record date is fixed, and in the event that such distribution is not so made, the Purchase Price shall be adjusted to be the Purchase Price which would have been in effect if such record date had not been fixed.

(d) (i) For the purpose of any computation hereunder, other than computations made pursuant to Section 11(a)(iii), the “current market price” per Common Share on any date shall be deemed to be the average of the daily closing prices per such Common Share for the thirty (30) consecutive Trading Days immediately prior to but not including such date, and for purposes of computations made pursuant to Section 11(a)(iii), the “current market price” per Common Share on any date shall be deemed to be the average of the daily closing prices per such Common Share for the ten (10) consecutive Trading Days immediately following but not including such date; provided , however , that in the event that the current market price per Common Share is determined during a period following the announcement by the issuer of such Common Shares of (A) a dividend or distribution on such Common Shares payable in such Common Shares or securities convertible into such Common Shares (other than the Rights), or (B) any subdivision, combination or reclassification of such Common Shares, and the ex-dividend date for such dividend or distribution, or the record date for such subdivision, combination or reclassification shall not have occurred prior to the commencement of the requisite thirty (30) Trading Day or ten (10) Trading Day period, as set forth above, then, and in each such case, the “current market price” shall be properly adjusted to take into account any trading during the period prior to such ex-dividend date or record date. The closing price for each day shall be the last sale price, regular way, or, in case no such sale takes place on such day, the average of the closing bid and asked prices, regular way, in either case as reported in the principal consolidated transaction reporting system with respect to securities listed or admitted to trading on the New York Stock Exchange or, if the Common Shares are not listed or admitted to trading on the New York Stock Exchange, as reported in the principal consolidated transaction reporting system with respect to securities listed on the principal national securities exchange on which the Common Shares are listed or admitted to trading or, if the Common Shares are not listed or admitted to trading on any national securities exchange, the last quoted price or, if not so quoted, the average of the high bid and low asked prices in the over-the-counter market, as reported by the OTC Bulletin Board service (the “OTCBB”) or such other quotation

18

system then in use, or, if on any such date the Common Shares are not quoted by any such organization, the average of the closing bid and asked prices as furnished by a professional market maker making a market in the Common Shares selected by the Board of Directors of the Company. If on any such date no market maker is making a market in the Common Shares, the fair value of such shares on such date as determined in good faith by the Board of Directors of the Company shall be used. The term “Trading Day” shall mean a day on which the principal national securities exchange on which the Common Shares are listed or admitted to trading is open for the transaction of business or, if the Common Shares are not listed or admitted to trading on any national securities exchange, a Business Day. If the Common Shares are not publicly held or not so listed or traded, “current market price” per share shall mean the fair value per share as determined in good faith by the Board of Directors of the Company, whose determination shall be described in a statement filed with the Rights Agent and shall be conclusive for all purposes.

(ii) For the purpose of any computation hereunder, the “current market price” per Preferred Share shall be determined in the same manner as set forth above for the Common Shares in clause (i) of this Section 11(d) (other than the last sentence thereof). If the current market price per Preferred Share cannot be determined in the manner provided above, or if the Preferred Shares are not publicly held or listed or traded in a manner described in clause (i) of this Section 11(d), the “current market price” per Preferred Share shall be conclusively deemed to be an amount equal to 1,000 (as such number may be appropriately adjusted for such events as share splits, share dividends and recapitalizations with respect to the Common Shares occurring after the date of this Agreement) multiplied by the current market price per Common Share. If neither the Common Shares nor the Preferred Shares are publicly held or so listed or traded, “current market price” per Preferred Share shall mean the fair value per share as determined in good faith by the Board of Directors of the Company, whose determination shall be described in a statement filed with the Rights Agent and shall be binding on the Rights Agent and the holders of the Rights. For all purposes of this Agreement, the “current market price” of one one-thousandth of a Preferred Share shall be equal to the “current market price” of one Preferred Share divided by 1,000.

(e) Anything herein to the contrary notwithstanding, no adjustment in the Purchase Price shall be required unless such adjustment would require an increase or decrease of at least one percent (1%) in the Purchase Price; provided , however , that any adjustments which by reason of this Section 11(e) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Section 11 shall be made to the nearest cent or to the nearest one ten-thousandth of a Common Share or one one-millionth of a Preferred Share or one ten-thousandth of any other share or security, as the case may be. Notwithstanding the first sentence of this Section 11(e), any adjustment required by this Section 11 shall be made no later than the earlier of (i) three (3) years from the date of the transaction which mandates such adjustment, or (ii) the Expiration Date.

19

(f) If as a result of an adjustment made pursuant to Section 11(a)(ii), the holder of any Right thereafter exercised shall become entitled to receive any shares of capital shares other than Preferred Shares, thereafter the number of such other shares so receivable upon exercise of any Right and the Purchase Price thereof shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to the Preferred Shares contained in Sections 11(a), (b), (c), (e), (g), (h), (i), (j), (k) and (m), and the provisions of Sections 7, 9, 10 and 14 with respect to the Preferred Shares shall apply on like terms to any such other shares.

(g) All Rights originally issued by the Company subsequent to any adjustment made to the Purchase Price hereunder shall evidence the right to purchase, at the adjusted Purchase Price, the number of one one-thousandths of a Preferred Share purchasable from time to time hereunder upon exercise of the Rights, all subject to further adjustment as provided herein.

(h) Unless the Company shall have exercised its election as provided in Section 11(i), upon each adjustment of the Purchase Price as a result of the calculations made in Sections 11(b) and (c), each Right outstanding immediately prior to the making of such adjustment shall thereafter evidence the right to purchase, at the adjusted Purchase Price, that number of one-thousandths of a Preferred Share (calculated to the nearest one-millionth) obtained by (i) multiplying (x) the number of one one-thousandths of a share covered by a Right immediately prior to this adjustment, by (y) the Purchase Price in effect immediately prior to such adjustment of the Purchase Price, and (ii) dividing the product so obtained by the Purchase Price in effect immediately after such adjustment of the Purchase Price.

(i) The Company may elect on or after the date of any adjustment of the Purchase Price to adjust the number of Rights, in lieu of any adjustment in the number of one one-thousandths of a Preferred Share purchasable upon the exercise of a Right. Each of the Rights outstanding after the adjustment in the number of Rights shall be exercisable for the number of one one-thousandths of a Preferred Share for which a Right was exercisable immediately prior to such adjustment. Each Right held of record prior to such adjustment of the number of Rights shall become that number of Rights (calculated to the nearest one-ten-thousandth) obtained by dividing the Purchase Price in effect immediately prior to adjustment of the Purchase Price by the Purchase Price in effect immediately after adjustment of the Purchase Price. The Company shall make a public announcement (with prompt notice thereof to the Rights Agent) of its election to adjust the number of Rights, indicating the record date for the adjustment, and, if known at the time, the amount of the adjustment to be made. This record date may be the date on which the Purchase Price is adjusted or any day thereafter, but, if the Rights Certificates have been issued, shall be at least ten (10) days later than the date of the public announcement. If Rights Certificates have been issued, upon each adjustment of the number of Rights pursuant to this Section 11(i), the Company shall, as promptly as practicable, cause to be distributed to holders of record of Rights Certificates on such record date Rights Certificates evidencing, subject to Section 14, the additional Rights to which such holders shall be entitled as a result of such adjustment, or, at the option of the Company, shall cause to be distributed to such holders of record in substitution and replacement for the Rights Certificates held by such holders prior to the date of adjustment, and upon surrender thereof, if required by the Company, new Rights

20

Certificates evidencing all the Rights to which such holders shall be entitled after such adjustment. Rights Certificates so to be distributed shall be issued, executed and countersigned in the manner provided for herein (and may bear, at the option of the Company, the adjusted Purchase Price) and shall be registered in the names of the holders of record of Rights Certificates on the record date specified in the public announcement.

(j) Irrespective of any adjustment or change in the Purchase Price or the number of one one-thousandths of a Preferred Share issuable upon the exercise of the Rights, the Rights Certificates theretofore and thereafter issued may continue to express the Purchase Price per one one-thousandth of a share and the number of one one-thousandths of a share which were expressed in the initial Rights Certificates issued hereunder.

(k) Before taking any action that would cause an adjustment reducing the Purchase Price below the then stated value, if any, of the number of one one-thousandths of a Preferred Share issuable upon exercise of the Rights, the Company shall take any corporate action which may, in the opinion of its counsel, be necessary in order that the Company may validly and legally issue fully paid and nonassessable Preferred Shares at such adjusted Purchase Price.

(l) In any case in which this Section 11 shall require that an adjustment in the Purchase Price be made effective as of a record date for a specified event, the Company may elect to defer until the occurrence of such event the issuance to the holder of any Right exercised after such record date the number of one one-thousandths of a Preferred Share and other capital shares or securities of the Company, if any, issuable upon such exercise over and above the number of one one-thousandths of a Preferred Share and other capital shares or securities of the Company, if any, issuable upon such exercise on the basis of the Purchase Price in effect prior to such adjustment (and shall provide the Rights Agent prompt notice of such election); provided , however , that the Company shall deliver to such holder a due bill or other appropriate instrument evidencing such holder’s right to receive such additional shares (fractional or otherwise) or securities upon the occurrence of the event requiring such adjustment.

(m) Anything in this Section 11 to the contrary notwithstanding, the Company shall be entitled to make such reductions in the Purchase Price, in addition to those adjustments expressly required by this Section 11, as and to the extent that the Board of Directors of the Company, in its good faith judgment, shall determine to be advisable in order that any (i) consolidation or subdivision of the Preferred Shares, (ii) issuance wholly for cash of any Preferred Shares at less than the current market price, (iii) issuance wholly for cash of Preferred Shares or securities which by their terms are convertible into or exchangeable for Preferred Shares, (iv) share dividends or (v) issuance of rights, options or warrants referred to in this Section 11, hereafter made by the Company to holders of its Preferred Shares shall not be taxable to such shareholders.

(n) The Company covenants and agrees that it shall not, at any time after the Distribution Date, (i) consolidate with any other Person (other than a Subsidiary of the Company in a transaction which complies with Section 11(o)), (ii) merge with or into any other Person (other than a Subsidiary of the Company in a transaction which complies with Section 11(o)), or

(iii) sell or transfer (or permit any Subsidiary to sell or transfer), in one transaction, or a series of related transactions, assets, cash flow or earning power aggregating more than 50% of the assets, cash flow or earning power of the Company and its Subsidiaries (taken as a whole) to any other Person or Persons (other than the Company and/or any of its Subsidiaries in one or more transactions each of which complies with Section 11(o)), if at the time of or immediately after such consolidation, merger, sale or transfer there are any rights, warrants or other instruments or securities outstanding or agreements in effect which would substantially diminish or otherwise eliminate the benefits intended to be afforded by the Rights.

(o) The Company covenants and agrees that, after the Distribution Date, it will not, except as permitted by Section 23, Section 24 or Section 27, take (or permit any Subsidiary to take) any action if at the time such action is taken it is reasonably foreseeable that such action will diminish substantially or otherwise eliminate the benefits intended to be afforded by the Rights.

(p) In the event that the Company shall at any time after the Rights Dividend Declaration Date and prior to the Distribution Date (i) declare a dividend on the outstanding Common Shares payable in Common Shares, (ii) subdivide the outstanding Common Shares, or (iii) combine the outstanding Common Shares into a smaller number of shares, the number of Rights associated with each Common Share then outstanding, or issued or delivered thereafter but prior to the Distribution Date, shall be proportionately adjusted so that the number of Rights thereafter associated with each Common Share following any such event shall equal the result obtained by multiplying the number of Rights associated with each Common Share immediately prior to such event by a fraction the numerator of which shall be the total number of Common Shares outstanding immediately prior to the occurrence of the event and the denominator of which shall be the total number of Common Shares outstanding immediately following the occurrence of such event.

Section 12. Certificate of Adjusted Purchase Price or Number of Shares . Whenever an adjustment is made as provided in Section 11, the Company shall (a) promptly prepare a certificate setting forth such adjustment and a brief statement of the facts and computations accounting for such adjustment, (b) promptly file with the Rights Agent, and with each transfer agent for the Preferred Shares and the Common Shares, a copy of such certificate, and (c) if a Distribution Date has occurred, mail a brief summary thereof to each holder of a Rights Certificate in accordance with Section 26. The Rights Agent shall be fully protected in relying on any such certificate and on any adjustment therein contained and shall not be deemed to have knowledge of such adjustment unless and until it shall have received such certificate.

Section 13. [Reserved] .

Section 14. Fractional Rights and Fractional Shares .

(a) The Company shall not be required to issue fractions of Rights, except prior to the Distribution Date as provided in Section 11, or to distribute Rights Certificates which evidence fractional Rights. In lieu of such fractional Rights, the Company shall pay or cause to be paid to the registered holders of the Rights Certificates with regard to which such fractional

22

Rights would otherwise be issuable, an amount in cash equal to the same fraction of the current market value of a whole Right. For purposes of this Section 14(a), the current market value of a whole Right shall be the closing price of a Right for the Trading Day immediately prior to the date on which such fractional Rights would have been otherwise issuable. The closing price of a Right for any Trading Day shall be the last sale price, regular way, or, in case no such sale takes place on such day, the average of the closing bid and asked prices, regular way, in either case as reported in the principal consolidated transaction reporting system with respect to securities listed or admitted to trading on the New York Stock Exchange or, if the Rights are not listed or admitted to trading on the New York Stock Exchange, as reported to the principal consolidated transaction reporting system with respect to securities listed or admitted to trading on the principal national securities exchange on which the Rights are listed or admitted to trading, or if the Rights are not listed or admitted to trading on any national securities exchange, the last quoted price or, if not so quoted, the average of the high bid and low asked prices in the over-the-counter market, as reported by the OTCBB or such other system then in use or, if on any such date the Rights are not quoted by any such organization, the average of the closing bid and asked prices as furnished by a professional market maker making a market in the Rights selected by the Board of Directors of the Company. If on any such date no such market maker is making a market in the Rights, the fair value of the Rights on such date as determined in good faith by the Board of Directors of the Company shall be used.

(b) The Company shall not be required to issue fractions of Preferred Shares (other than fractions which are integral multiples of one one-thousandth of a Preferred Share) upon exercise of the Rights or to distribute certificates which evidence fractional Preferred Shares (other than fractions which are integral multiples of one one-thousandth of a Preferred Share). Fractions of Preferred Shares in integral multiples of one one-thousandth of a share may, at the election of the Company, be evidenced by depositary receipts pursuant to an appropriate agreement between the Company and a depositary selected by it; provided , however , that such agreement shall provide that the holders of such depositary receipts shall have all the rights, privileges and preferences to which they are entitled as beneficial owners of the shares represented by such depositary receipts. In lieu of fractional Preferred Shares that are not integral multiples of one one-thousandth of a Preferred Share, the Company shall pay to the registered holders of Rights Certificates at the time such Rights are exercised as herein provided an amount in cash equal to the same fraction of the current market value of one one-thousandth of a Preferred Share. For purposes of this Section 14(b), the current market value of one one-thousandth of a Preferred Share shall be one one-thousandth of the closing price of a Preferred Share (as determined pursuant to Section 11(d)(ii)) for the Trading Day immediately prior to the date of such exercise; provided , however , that if the closing price of the Preferred Shares cannot be so determined, the closing price of one Preferred Share for such Trading Day shall be conclusively deemed to be an amount equal to the closing price of one Common Share for such Trading Day multiplied by one hundred (as such number may be appropriately adjusted by the Company’s Board of Directors, in its judgment, to reflect events such as share splits, share dividends, recapitalizations or similar transactions relating to the Common Shares occurring after the date of this Agreement).

(c) Following the occurrence of a Section 11(a)(ii) Event, the Company shall not be required to issue fractions of Common Shares upon exercise of the Rights or to distribute

23

certificates which evidence fractional Common Shares. In lieu of fractional Common Shares, the Company shall pay to the registered holders of Rights Certificates at the time such Rights are exercised as herein provided an amount in cash equal to the same fraction of the current market value of one Common Share. For purposes of this Section 14(c), the current market value of one Common Share shall be the closing price of one Common Share (as determined pursuant to Section 11(d)(i)) for the Trading Day immediately prior to the date of such exercise.

(d) The holder of a Right by the acceptance of the Rights expressly waives such holder’s right to receive any fractional Rights or any fractional shares upon exercise of a Right, except as permitted by this Section 14.

(e) Whenever a payment for fractional Rights or fractional shares is to be made by the Rights Agent, the Company shall (i) promptly prepare and deliver to the Rights Agent a certificate setting forth in reasonable detail the facts related to such payment and the prices and/or formulas utilized in calculating such payments, and (ii) provide sufficient monies to the Rights Agent in the form of fully collected funds to make such payments.

Section 15. Rights of Action . All rights of action in respect of this Agreement, other than rights of action vested in the Rights Agent pursuant to the terms of this Agreement, are vested in the respective registered holders of the Rights Certificates (and, prior to the Distribution Date, the registered holders of the Common Shares); and any registered holder of any Rights Certificate (or, prior to the Distribution Date, of the Common Shares), without the consent of the Rights Agent or of the holder of any other Rights Certificate (or, prior to the Distribution Date, of the Common Shares), may, in such holder’s own behalf and for such holder’s own benefit, enforce, and may institute and maintain any suit, action or proceeding against the Company to enforce, or otherwise act in respect of, such holder’s right to exercise the Rights evidenced by such Rights Certificate in the manner provided in such Rights Certificate and in this Agreement. Without limiting the foregoing or any remedies available to the holders of Rights, it is specifically acknowledged that the holders of Rights would not have an adequate remedy at law for any breach of this Agreement and shall be entitled to specific performance of the obligations hereunder and injunctive relief against actual or threatened violations of the obligations hereunder of any Person subject to this Agreement.

Section 16. Agreement of Rights Holders . Every holder of a Right by accepting the same consents and agrees with the Company and the Rights Agent and with every holder of a Right that:

(a) prior to the Distribution Date, the Rights will be transferable only in connection with the transfer of Common Shares;

(b) after the Distribution Date, the Rights Certificates are transferable only on the registry books of the Rights Agent if surrendered at the principal office or offices of the Rights Agent designated for such purposes, duly endorsed or accompanied by a proper instrument of transfer and with the appropriate forms and certificates fully executed;

24

(c) subject to Section 6(a) and Section 7(f), the Company and the Rights Agent may deem and treat the person in whose name a Rights Certificate (or, prior to the Distribution Date, the associated Common Shares certificate) is registered as the absolute owner thereof and of the Rights evidenced thereby (notwithstanding any notations of ownership or writing on any Rights Certificate or associated Common Shares certificate made by anyone other than the Company or the Rights Agent) for all purposes whatsoever, and neither the Company nor the Rights Agent, subject to the last sentence of Section 7(e), shall be required to be affected by any notice to the contrary; and

(d) notwithstanding anything in this Agreement to the contrary, neither the Company nor the Rights Agent shall have any liability to any holder of a Right or other Person as a result of its inability to perform any of its obligations under this Agreement by reason of any preliminary or permanent injunction or other order, decree, judgment or ruling issued by any court of competent jurisdiction or by any governmental, regulatory or administrative agency or commission, or any statute, rule, regulation or executive order promulgated or enacted by any governmental authority, prohibiting or otherwise restraining performance of such obligation; provided , however , that the Company shall use commercially reasonable efforts to have any such order, decree, judgment or ruling lifted or otherwise overturned as soon as possible.

Section 17. Rights Certificate Holder Not Deemed a Shareholder . No holder, as such, of any Rights Certificate shall be entitled to vote, receive dividends or be deemed for any purpose to be the holder of the number of one one-thousandths of a Preferred Share or any other securities of the Company which may at any time be issuable upon the exercise of the Rights represented thereby, nor shall anything contained herein or in any Rights Certificate be construed to confer upon the holder of any Rights Certificate, as such, any of the rights of a shareholder of the Company or any right to vote for the election of directors or upon any matter submitted to shareholders at any meeting thereof, or to give or withhold consent to any corporate action, or to receive notice of meetings or other actions affecting shareholders (except as provided in Section 25), or to receive dividends or subscription rights, or otherwise, until the Right or Rights evidenced by such Rights Certificate shall have been exercised in accordance with the provisions hereof.

Section 18. Concerning the Rights Agent .

(a) The Company agrees to pay to the Rights Agent reasonable compensation for all services rendered by it hereunder and, from time to time, on demand of the Rights Agent, its reasonable expenses and counsel fees and disbursements and other disbursements incurred in the preparation, execution, delivery and amendment of this Agreement and the exercise and performance of its duties hereunder. The Company also agrees to indemnify the Rights Agent for, and to hold it harmless against, any loss, liability, damage, judgment, fine, penalty, claim, demand, settlement, cost or expense incurred without gross negligence, bad faith or willful misconduct on the part of the Rights Agent for any action taken, suffered or omitted by the Rights Agent in connection with the acceptance and administration of this Agreement, including, without limitation, the reasonable costs and expenses of defending against any claim of liability in the premises.

25

(b) The Rights Agent shall be authorized and protected and shall incur no liability for or in respect of any action taken, suffered or omitted by it in connection with its acceptance and administration of this Agreement in reliance upon any Rights Certificate or certificate for Common Shares or for other securities of the Company, instrument of assignment or transfer, power of attorney, endorsement, affidavit, letter, notice, direction, consent, certificate, statement, or other paper or document believed by it to be genuine and to be signed, executed and, where necessary, verified or acknowledged, by the proper Person or Persons, or otherwise upon the advice of counsel as set forth in Section 20.

Section 19. Merger or Consolidation or Change of Name of Rights Agent .

(a) Any Person into which the Rights Agent or any successor Rights Agent may be merged or with which it may be consolidated, or any Person resulting from any merger or consolidation to which the Rights Agent or any successor Rights Agent shall be a party, or any Person succeeding to the stock transfer business of the Rights Agent or any successor Rights Agent, shall be the successor to the Rights Agent under this Agreement without the execution or filing of any paper or any further act on the part of any of the parties hereto; provided , however , that such Person would be eligible for appointment as a successor Rights Agent under the provisions of Section 21. In case at the time such successor Rights Agent shall succeed to the agency created by this Agreement, any of the Rights Certificates shall have been countersigned but not delivered, any such successor Rights Agent may adopt the countersignature of a predecessor Rights Agent and deliver such Rights Certificates so countersigned; and in case at the time any of the Rights Certificates shall not have been countersigned, any successor Rights Agent may countersign such Rights Certificates either in the name of the predecessor or in the name of the successor Rights Agent; and in all such cases such Rights Certificates shall have the full force provided in the Rights Certificates and in this Agreement.

(b) In case at any time the name of the Rights Agent shall be changed, and at such time any of the Rights Certificates shall have been countersigned but not delivered, the Rights Agent may adopt the countersignature under its prior name and deliver Rights Certificates so countersigned; and in case, at that time, any of the Rights Certificates shall not have been countersigned, the Rights Agent may countersign such Rights Certificates either in its prior name or in its changed name; and in all such cases such Rights Certificates shall have the full force provided in the Rights Certificates and in this Agreement.

Section 20. Duties of Rights Agent . The Rights Agent undertakes only the duties and obligations expressly imposed by this Agreement upon the following terms and conditions, by all of which the Company and the holders of Rights Certificates, by their acceptance thereof, shall be bound:

(a) Before the Rights Agent acts or refrains from acting, the Rights Agent may consult with legal counsel (who may be legal counsel for the Company), and the opinion of such counsel shall be full and complete authorization and protection to the Rights Agent as to any action taken or omitted by it in good faith and in accordance with such opinion.

26

(b) Whenever in the performance of its duties under this Agreement the Rights Agent shall deem it necessary or desirable that any fact or matter (including, without limitation, the identity of any Acquiring Person and the determination of “current market price”) be proved or established by the Company prior to taking, suffering or omitting to take any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and established by a certificate signed by the Chairman of the Board, the President, any Vice President, the Treasurer, any Assistant Treasurer, the Secretary or any Assistant Secretary of the Company and delivered to the Rights Agent; and such certificate shall be full authorization and protection to the Rights Agent, and the Rights Agent shall incur no liability for or in respect of any action taken, suffered or omitted to be taken by it in good faith by it under the provisions of this Agreement in reliance upon such certificate.

(c) The Rights Agent shall be liable hereunder only for its own gross negligence, bad faith or willful misconduct.

(d) The Rights Agent shall not be liable for or by reason of any of the statements of fact or recitals contained in this Agreement or in the Rights Certificates or be required to verify the same (except as to its countersignature on such Rights Certificates), but all such statements and recitals are and shall be deemed to have been made by the Company only.

(e) The Rights Agent shall not be under any responsibility in respect of the validity of this Agreement or the execution and delivery hereof (except the due execution hereof by the Rights Agent) or in respect of the validity or execution of any Rights Certificate (except its countersignature thereof); nor shall it be responsible for any breach by the Company of any covenant or condition contained in this Agreement or in any Rights Certificate; nor shall it be responsible for any adjustment required under the provisions of Section 11 or Section 24 or responsible for the manner, method or amount of any such adjustment or the ascertaining of the existence of facts that would require any such adjustment (except with respect to the exercise of Rights evidenced by Rights Certificates after actual notice of any such adjustment); nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any Common Shares or Preferred Shares to be issued pursuant to this Agreement or any Rights Certificate or as to whether any Common Shares or Preferred Shares will, when so issued, be validly authorized and issued, fully paid and nonassessable.

(f) The Company agrees that it will perform, execute, acknowledge and deliver or cause to be performed, executed, acknowledged and delivered all such further and other acts, instruments and assurances as may reasonably be required by the Rights Agent for the carrying out or performing by the Rights Agent of the provisions of this Agreement.

(g) The Rights Agent is hereby authorized and directed to accept instructions with respect to the performance of its duties hereunder from the Chairman of the Board, the President, any Vice President, the Secretary, any Assistant Secretary, the Treasurer or any Assistant Treasurer of the Company, and to apply to such officers for advice or

27

instructions in connection with its duties, and it shall incur no liability for or in respect of any action taken, suffered or omitted by it in good faith in accordance with instructions of any such officer.

(h) The Rights Agent and any shareholder, director, Affiliate, officer or employee of the Rights Agent may buy, sell or deal in any of the Rights or other securities of the Company or become pecuniarily interested in any transaction in which the Company may be interested, or contract with or lend money to the Company or otherwise act as fully and freely as though it were not Rights Agent under this Agreement. Nothing herein shall preclude the Rights Agent from acting in any other capacity for the Company or for any other Person.

(i) The Rights Agent may execute and exercise any of the rights or powers hereby vested in it or perform any duty hereunder either itself or by or through its attorneys or agents, and the Rights Agent shall not be answerable or accountable for any act, default, neglect or misconduct of any such attorneys or agents or for any loss to the Company resulting from any such act, default, neglect or misconduct; provided , however , that reasonable care was exercised in the selection and continued employment thereof.

(j) No provision of this Agreement shall require the Rights Agent to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or in the exercise of its rights if there shall be reasonable grounds for believing that repayment of such funds or adequate indemnification against such risk or liability is not reasonably assured to it.

(k) If, with respect to any Rights Certificate surrendered to the Rights Agent for exercise or transfer, the certificate attached to the form of assignment or form of election to purchase, as the case may be, has either not been completed or indicates an affirmative response to clause 1 and/or 2 thereof, the Rights Agent shall not take any further action with respect to such requested exercise or transfer without first consulting with the Company.

(l) At any time and from time to time after the Distribution Date, upon the request of the Company, the Rights Agent shall deliver to the Company a list, as of the most recent practicable date (or as of such earlier date as may be specified by the Company), of the holders of record of the Rights.

Section 21. Change of Rights Agent . The Rights Agent or any successor Rights Agent may resign and be discharged from its duties under this Agreement upon thirty (30) days’ notice in writing mailed to the Company, and in the event that the Rights Agent or one of its Affiliates is not also the transfer agent for the Company, to each transfer agent of the Common Shares and Preferred Shares, by registered or certified mail. In the event the transfer agency relationship in effect between the Company and the Rights Agent with respect to the Common Shares terminates, the Rights Agent will be deemed to have resigned automatically and be discharged from its duties under this Agreement as of the effective date of such termination, and the Company shall be responsible for sending any notice required pursuant to the preceding

28

sentence. The Company may remove the Rights Agent or any successor Rights Agent upon thirty (30) days’ notice in writing, mailed to the Rights Agent or successor Rights Agent, as the case may be, and to each transfer agent of the Common Shares and Preferred Shares, by registered or certified mail, and to the holders of the Rights Certificates by first-class mail. If the Rights Agent shall resign or be removed or shall otherwise become incapable of acting, the Company shall appoint a successor to the Rights Agent. If the Company shall fail to make such appointment within a period of thirty (30) days after giving notice of such removal or after it has been notified in writing of such resignation or incapacity by the resigning or incapacitated Rights Agent or by any registered holder of a Rights Certificate (who shall, with such notice, submit such holder’s Rights Certificate for inspection by the Company), then any registered holder of any Rights Certificate may apply to any court of competent jurisdiction for the appointment of a new Rights Agent. Any successor Rights Agent, whether appointed by the Company or by such a court, shall be (a) a Person organized and doing business under the laws of the United States or of the State of Michigan or the State of New York (or of any other state of the United States so long as such Person is authorized to do business in the State of Michigan or the State of New York), in good standing, which is authorized under such laws to exercise stock transfer powers and is subject to supervision or examination by federal or state authority and which has at the time of its appointment as Rights Agent a combined capital and surplus of at least $50,000,000 or (b) an Affiliate of such Person. After appointment, the successor Rights Agent shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named as Rights Agent without further act or deed; but the predecessor Rights Agent shall deliver and transfer to the successor Rights Agent any property at the time held by it hereunder, and execute and deliver any further reasonable assurance, conveyance, act or deed necessary for the purpose. Not later than the effective date of any such appointment, the Company shall file notice thereof in writing with the predecessor Rights Agent and each transfer agent of the Common Shares and the Preferred Shares, and mail a notice thereof in writing to the registered holders of the Rights Certificates. Failure to give any notice provided for in this Section 21 or any defect therein shall not affect the legality or validity of the resignation or removal of the Rights Agent or the appointment of the successor Rights Agent, as the case may be.

Section 22. Issuance of New Rights Certificates . Notwithstanding any of the provisions of this Agreement or of the Rights to the contrary, the Company may, at its option, issue new Rights Certificates evidencing Rights in such form as may be approved by its Board of Directors to reflect any adjustment or change in the Purchase Price and the number or kind or class of shares or other securities or property purchasable under the Rights Certificates made in accordance with the provisions of this Agreement. In addition, in connection with the issuance or sale of Common Shares following the Distribution Date and prior to the redemption or expiration of the Rights, the Company (a) shall, with respect to Common Shares so issued or sold pursuant to the exercise of share options or under any employee plan or arrangement, granted or awarded prior to the Distribution Date, or upon the exercise, conversion or exchange of securities hereinafter issued by the Company, and (b) may, in any other case, if deemed necessary or appropriate by the Board of Directors of the Company, issue Rights Certificates representing an appropriate number of Rights in connection with such issuance or sale; provided , however , that (i) no such Rights Certificate shall be issued if, and to the extent that, the Company shall be advised by counsel that such issuance would create a significant risk of material adverse tax consequences to the Company or the Person to whom such Rights Certificate would be issued,

29

and (ii) no such Rights Certificate shall be issued if, and to the extent that, appropriate adjustment shall otherwise have been made in lieu of the issuance thereof.

Section 23. Redemption and Termination .

(a) The Board of Directors of the Company may, at its option, at any time prior to the earlier of (i) the Close of Business on the tenth day following the Share Acquisition Date (or, if the Share Acquisition Date shall have occurred prior to the Record Date, the Close of Business on the tenth day following the Record Date), or (ii) the Final Expiration Date, redeem all but not less than all of the then outstanding Rights at a redemption price of $0.001 per Right, as such amount may be appropriately adjusted to reflect any share split, share dividend or similar transaction occurring after the date hereof (such redemption price being hereinafter referred to as the “Redemption Price”). Notwithstanding anything contained in this Agreement to the contrary, the Rights shall not be exercisable after the first occurrence of a Section 11(a)(ii) Event until such time as the Company’s right of redemption hereunder has expired. The Company may, at its option, pay the Redemption Price in cash, Common Shares (based on the “current market price”, as defined in Section 11(d)(i), of the Common Shares at the time of redemption) or any other form of consideration deemed appropriate by the Board of Directors of the Company. The redemption of the Rights by the Board of Directors may be made effective at such time, on such basis and with such conditions as the Company’s Board of Directors in its sole discretion may establish.

(b) Immediately upon the action of the Board of Directors of the Company ordering the redemption of the Rights, evidence of which shall have been filed with the Rights Agent and without any further action and without any notice, the right to exercise the Rights will terminate and the only right thereafter of the holders of Rights shall be to receive the Redemption Price for each Right so held. Promptly after the action of the Board of Directors of the Company ordering the redemption of the Rights, the Company shall give notice of such redemption to the Rights Agent and the holders of the then outstanding Rights by mailing such notice to the Rights Agent and to all such holders at each holder’s last address as it appears upon the registry books of the Rights Agent or, prior to the Distribution Date, on the registry books of the transfer agent for the Common Shares. Any notice which is mailed in the manner herein provided shall be deemed given, whether or not the holder receives the notice. Each such notice of redemption will state the method by which the payment of the Redemption Price will be made.

30

Section 24. Exchange .

(a) The Board of Directors of the Company may, at its option, at any time after any Person becomes an Acquiring Person, exchange all or part of the then outstanding and exercisable Rights (which shall not include Rights that have become null and void pursuant to the provisions of Section 7(e)) for Common Shares at an exchange ratio of one Common Share per Right, appropriately adjusted to reflect any share split, share dividend or similar transaction occurring after the date hereof (such exchange ratio being hereinafter referred to as the “Exchange Ratio”). Notwithstanding the foregoing, the Board of Directors of the Company shall not be empowered to effect such exchange at any time after any Person (other than the Company, any Subsidiary of the Company, any employee benefit plan or other compensation arrangement of the Company or of any Subsidiary of the Company, any Person organized, appointed or established by the Company for or pursuant to the terms of any such plan or compensation arrangement, any member of the Pulte Family or any Pulte Group), together with all Affiliates and Associates of such Person, becomes the Beneficial Owner of fifty percent (50%) or more of the Common Shares then outstanding.

(b) Immediately upon the action of the Board of Directors of the Company ordering the exchange of any Rights pursuant to subsection (a) of this Section 24 and without any further action and without any notice, the right to exercise such Rights shall terminate and the only right thereafter of a holder of any such Rights shall be to receive that number of Common Shares equal to the number of such Rights held by such holder multiplied by the Exchange Ratio. The Company shall promptly give public notice (with prompt notice thereof to the Rights Agent) of any exchange; provided , however , that the failure to give, or any defect in, such notice shall not affect the validity of such exchange. The Company promptly shall mail a notice of any such exchange to all of the holders of such Rights at their last addresses as they appear upon the registry books of the Rights Agent. Any notice which is mailed in the manner herein provided shall be deemed given, whether or not the holder receives the notice. Each such notice of exchange will state the method by which the exchange of the Common Shares for Rights will be effected and, in the event of any partial exchange, the number of Rights which will be exchanged. Any partial exchange will be effected pro rata based on the number of Rights (other than Rights which have become null and void pursuant to the provisions of Section 7(e)) held by each holder of Rights.

(c) In any exchange pursuant to this Section 24, the Company, at its option, may substitute Preferred Shares (or equivalent preferred shares, as such term is defined in paragraph (b) of Section 11) for Common Shares exchangeable for Rights, at the initial rate of one one-thousandth of a Preferred Share (or equivalent preferred shares) for each Common Share, as appropriately adjusted to reflect adjustments in the voting rights of the Preferred Shares pursuant to the terms thereof, so that the fraction of a Preferred Share delivered in lieu of each Common Share shall have the same voting rights as one Common Share.

(d) In the event that there shall not be sufficient Common Shares issued but not outstanding or authorized but unissued to permit any exchange of Rights as contemplated in accordance with this Section 24, the Company shall take all such actions as may be necessary to authorize additional Common Shares for issuance upon exchange of the Rights.

31

(e) The Company shall not be required to issue fractions of Common Shares or to distribute certificates which evidence fractional Common Shares. In lieu of such fractional Common Shares, there shall be paid to the registered holders of the Rights Certificates with regard to which such fractional Common Shares would otherwise be issuable, an amount in cash equal to the same fraction of the current market value of a whole Common Share. For the purposes of this subsection (e), the current market value of a whole Common Share shall be the closing price of a Common Share (as determined pursuant to the second sentence of Section 11(d)(i)) for the Trading Day immediately prior to the date of exchange pursuant to this Section 24.

Section 25. Notice of Certain Events .

(a) In case the Company shall propose, at any time after the Distribution Date, (i) to pay any dividend payable in shares of any class to the holders of Preferred Shares or to make any other distribution to the holders of Preferred Shares (other than a regular periodic cash dividend out of earnings or retained earnings of the Company), (ii) to offer to the holders of Preferred Shares rights or warrants to subscribe for or to purchase any additional Preferred Shares or shares of any class or any other securities, rights or options, (iii) to effect any reclassification of its Preferred Shares (other than a reclassification involving only the subdivision of outstanding Preferred Shares), (iv) to effect any consolidation or merger into or with any other Person (other than a Subsidiary of the Company in a transaction which complies with Section 11(o)), or to effect any sale or other transfer (or to permit one or more of its Subsidiaries to effect any sale or other transfer), in one transaction or a series of related transactions, of more than 50% of the assets, cash flow or earning power of the Company and its Subsidiaries (taken as a whole) to any other Person or Persons (other than the Company and/or any of its Subsidiaries in one or more transactions each of which complies with Section 11(o)), or (v) to effect the liquidation, dissolution or winding up of the Company, then, in each such case, the Company shall give to the Rights Agent and to each holder of a Rights Certificate, to the extent feasible and in accordance with Section 26, a notice of such proposed action, which shall specify the record date for the purposes of such share dividend, distribution of rights or warrants, or the date on which such reclassification, consolidation, merger, sale, transfer, liquidation, dissolution, or winding up is to take place and the date of participation therein by the holders of the Preferred Shares, if any such date is to be fixed, and such notice shall be so given in the case of any action covered by clause (i) or (ii) above at least twenty (20) days prior to the record date for determining holders of the Preferred Shares for purposes of such action, and in the case of any such other action, at least twenty (20) days prior to the date of the taking of such proposed action or the date of participation therein by the holders of the Preferred Shares, whichever shall be the earlier.

(b) In case a Section 11(a)(ii) Event shall occur, then, in any such case, (i) the Company shall as soon as practicable thereafter give to each holder of a Rights Certificate, to the extent feasible and in accordance with Section 26, a notice of the occurrence of such event, which shall specify the event and the consequences of the event to holders of Rights under Section 11(a)(ii), and (ii) all references in the preceding paragraph to Preferred Shares shall be deemed thereafter to refer to Common Shares and/or, if appropriate, other securities.

32

(c) Failure to give notice required by this Section 25 or any defect therein shall not affect the legality or validity of the action taken by the Company or the vote on any such action.

CERTIFICATE OF DESIGNATION

OF

SERIES A JUNIOR PARTICIPATING PREFERRED SHARES

OF

PULTE HOMES, INC.

Pursuant to MCLA 450.1302; MSA 21.200 (302) of the

Michigan Business Corporation Act

The undersigned do hereby certify that the following resolution was duly adopted by the Board of Directors of Pulte Homes, Inc., a Michigan corporation (the “Corporation”), corporate id# 271982 on August 6, 2009:

WHEREAS, the Board of Directors of the Corporation duly adopted and filed a Certificate of Designation of Series A Junior Participating Preferred Shares with the Michigan Department of Energy, Labor and Economic Growth on March 5, 2009 (“Certificate of Designation”), designating an initial 400,000 shares of Series A Preferred Shares, and the Restated Articles of Incorporation of the Corporation, as amended (the “Charter”), allow the Board of Directors to increase the number of shares of such series; and

WHEREAS, the Board of directors wish to replace the Certificate of Designation in its entirety and adopt a new certificate of designation.

NOW, THEREFORE, BE IT RESOLVED, that pursuant to the authority vested in the Board of Directors of the Corporation by the Charter, the Board of Directors does hereby create, authorize and provide for the issue of a series of Preferred Shares, par value $.01 per share, of the Corporation, to be designated “Series A Junior Participating Preferred Shares” (hereinafter referred to as the “Series A Preferred Shares”), initially consisting of 500,000 shares, and to the extent that the designations, powers, preferences and relative and other special rights

A-1

and the qualifications, limitations or restrictions of the Series A Preferred Shares are not stated and expressed in the Charter, does hereby fix and herein state and express such designations, powers, preferences and relative and other special rights and the qualifications, limitations and restrictions thereof, as follows (all terms used herein which are defined in the Charter shall be deemed to have the meanings provided therein):

Section 1. Designation and Amount . The shares of such series shall be designated as “Series A Junior Participating Preferred Shares” and the number of shares constituting such series shall be 500,000.

Section 2. Dividends and Distributions .

(A) Subject to the prior and superior rights of the holders of any shares of any series of Preferred Shares ranking prior and superior to the shares of Series A Preferred Shares with respect to dividends, the holders of Series A Preferred Shares shall be entitled to receive, when, as and if declared by the Board of Directors out of funds legally available for the purpose, quarterly dividends payable in cash on the first business day of January, April, July and October in each year (each such date being referred to herein as a “Quarterly Dividend Payment Date”), commencing on the first Quarterly Dividend Payment Date after the first issuance of a share or fraction of a share of Series A Preferred Shares, in an amount per share (rounded to the nearest cent) equal to the greater of (a) $1.00 or (b) subject to the provision for adjustment hereinafter set forth, 1,000 times the aggregate per share amount of all cash dividends, plus 1,000 times the aggregate per share amount (payable in kind) of all non-cash dividends or other distributions other than a dividend payable in Common Shares or a subdivision of the outstanding Common Shares (by reclassification or otherwise), declared on the Common Shares, par value $.01 per share, of the Corporation (the “Common Shares”) since the immediately preceding Quarterly Dividend Payment Date, or, with respect to the first Quarterly Dividend Payment Date, since the first issuance of any share or fraction of a share of Series A Preferred Shares. In the event the Corporation shall at any time after March 16, 2009 (the “Rights Declaration Date”) (i) declare any dividend on Common Shares payable in Common Shares, (ii) subdivide the outstanding Common Shares, or (iii) combine the outstanding Common Shares into a smaller number of shares, then in each case the amount to which holders of Series A Preferred Shares were entitled immediately prior to such event under clause (b) of the preceding sentence shall be adjusted by multiplying such amount by a fraction the numerator of which is the number of Common Shares outstanding immediately after such event and the denominator of which is the number of Common Shares that were outstanding immediately prior to such event.

(B) The Corporation shall declare a dividend or distribution on the Series A Preferred Shares as provided in paragraph (A) above immediately after it declares a dividend or distribution on the Common Shares (other than a dividend payable in Common Shares); provided , however , that, in the event no dividend or distribution shall have been declared on the Common Shares during the period between any Quarterly Dividend Payment Date and the next subsequent Quarterly Dividend Payment Date, subject to the prior and superior rights of the holders of any shares of any series of Preferred Shares ranking prior to and superior to the Series A Preferred Shares with respect to dividends, a dividend of $1.00 per share on the Series A

A-2

Preferred Shares shall nevertheless be payable on such subsequent Quarterly Dividend Payment Date.

(C) Dividends shall begin to accrue and be cumulative on outstanding Series A Preferred Shares from the Quarterly Dividend Payment Date next preceding the date of issue of such Series A Preferred Shares, unless the date of issue of such shares is prior to the record date for the first Quarterly Dividend Payment Date, in which case dividends on such shares shall begin to accrue from the date of issue of such shares, or unless the date of issue is a Quarterly Dividend Payment Date or is a date after the record date for the determination of holders of Series A Preferred Shares entitled to receive a quarterly dividend and before such Quarterly Dividend Payment Date, in either of which events such dividends shall begin to accrue and be cumulative from such Quarterly Dividend Payment Date. Accrued but unpaid dividends shall not bear interest. Dividends paid on the Series A Preferred Shares in an amount less than the total amount of such dividends at the time accrued and payable on such shares shall be allocated pro rata on a share-by-share basis among all such shares at the time outstanding. The Board of Directors may fix a record date for the determination of holders of Series A Preferred Shares entitled to receive payment of a dividend or distribution declared thereon, which record date shall be no more than 60 days prior to the date fixed for the payment thereof.

Section 3. Voting Rights .

The holders of Series A Preferred Shares shall have the following voting rights:

(A) Subject to the provision for adjustment hereinafter set forth, each share of Series A Preferred Shares shall entitle the holder thereof to 1,000 votes on all matters submitted to a vote of the shareholders of the Corporation. In the event the Corporation shall at any time after the Rights Declaration Date (i) declare any dividend on Common Shares payable in Common Shares, (ii) subdivide the outstanding Common Shares, or (iii) combine the outstanding Common Shares into a smaller number of shares, then in each such case the number of votes per share to which holders of Series A Preferred Shares were entitled immediately prior to such event shall be adjusted by multiplying such number by a fraction the numerator of which is the number of Common Shares outstanding immediately after such event and the denominator of which is the number of Common Shares that were outstanding immediately prior to such event.

(B) Except as otherwise provided herein or by law, the holders of Series A Preferred Shares and the holders of Common Shares shall vote collectively as one class on all matters submitted to a vote of shareholders of the Corporation.

(C) (i) If at any time dividends on any Series A Preferred Shares shall be in arrears in an amount equal to six (6) quarterly dividends thereon, the occurrence of such contingency shall mark the beginning of a period (herein called a “default period”) which shall extend until such time when all accrued and unpaid dividends for all previous quarterly dividend periods and for the current quarterly dividend period on all Series A Preferred Shares then outstanding shall have been declared and paid or set apart for payment. During each default period, all holders of Preferred Shares (including, without limitation, holders of the Series A

A-3

Preferred Shares) with dividends in arrears in an amount equal to six (6) quarterly dividends thereon, voting as a class, irrespective of series, shall have the right to elect two (2) Directors.

(ii) During any default period, such voting right of the holders of Series A Preferred Shares may be exercised initially at a special meeting called pursuant to subparagraph (iii) of this Section 3(C) or at any annual meeting of shareholders, and thereafter at annual meetings of shareholders, provided that such voting right shall not be exercised unless the holders of ten percent (10%) in number of Preferred Shares outstanding shall be present in person or by proxy. The absence of a quorum of the holders of Common Shares shall not affect the exercise by the holders of Preferred Shares of such voting rights. At any meeting at which the holders of Preferred Shares shall exercise such voting right initially during an existing default period, they shall have the right, voting as a class, to elect Directors to fill such vacancies, if any, in the Board of Directors as may then exist up to two (2) Directors or, if such right is exercised at an annual meeting, to elect two (2) Directors. If the number which may be so elected at any special meeting does not amount to the required number, the holders of the Preferred Shares shall have the right to make such increase in the number of Directors as shall be necessary to permit the election by them of the required number. After the holders of the Preferred Shares shall have exercised their right to elect Directors in any default period and during the continuance of such period, the number of Directors shall not be increased or decreased except by vote of the holders of Preferred Shares as herein provided or pursuant to the rights of any equity securities ranking senior to or pari passu with the Series A Preferred Shares.

(iii) Unless the holders of Preferred Shares shall, during an existing default period, have previously exercised their right to elect Directors, the Board of Directors may order, or any shareholder or shareholders owning in the aggregate not less than ten percent (10%) of the total number of Preferred Shares outstanding, irrespective of series, may request, the calling of special meeting of the holders of Preferred Shares, which meeting shall thereupon be called by the Chairman of the Board, the President, a Vice President or the Secretary of the Corporation. Notice of such meeting and of any annual meeting at which holders of Preferred Shares are entitled to vote pursuant to this paragraph (C)(iii) shall be given to each holder of record of Preferred Shares by mailing a copy of such notice to him or her at his or her last address as the same appears on the books of the Corporation. Such meeting shall be called for a time not earlier than 10 days and not later than 50 days after such order or request, or in default of the calling of such meeting within 50 days after such order or request, such meeting may be called on similar notice by any shareholder or shareholders owning in the aggregate not less than ten percent (10%) of the total number of Preferred Shares outstanding. Notwithstanding the provisions of this paragraph (C)(iii), no such special meeting shall be called during the period within 50 days immediately preceding the date fixed for the next annual meeting of the shareholders.

(iv) In any default period, the holders of Common Shares, and, if applicable, other classes of capital shares of the Corporation, shall continue to be entitled to elect the whole number of Directors until the holders of Preferred Shares shall have exercised their

A-4

right to elect two (2) Directors voting as a class, after the exercise of which right (x) the Directors so elected by the holders of Preferred Shares shall continue in office until their successors shall have been elected by such holders or until the expiration of the default period, and (y) any vacancy in the Board of Directors may (except as provided in paragraph (C)(ii) of this Section 3) be filled by vote of a majority of the remaining Directors theretofore elected by the holders of the class of capital shares which elected the Director whose office shall have become vacant. References in this paragraph (C) to Directors elected by the holders of a particular class of shares shall include Directors appointed by such Directors to fill vacancies as provided in clause (y) of the foregoing sentence.

(v) Immediately upon the expiration of a default period, (x) the right of the holders of Preferred Shares as a class to elect Directors shall cease, (y) the term of any Directors elected by the holders of Preferred Shares as a class shall terminate, and (z) the number of Directors shall be such number as may be provided for in the articles of incorporation, as amended, or by-laws irrespective of any increase made pursuant to the provisions of paragraph (C)(ii) of this Section 3 (such number being subject, however, to change thereafter in any manner provided by law or in the articles of incorporation, as amended, or by-laws). Any vacancies in the Board of Directors effected by the provisions of clauses (y) and (z) in the preceding sentence may be filled by a majority of the remaining Directors.

(D) Except as set forth herein, holders of Series A Preferred Shares shall have no special voting rights and their consent shall not be required (except to the extent they are entitled to vote with holders of Common Shares as set forth herein) for taking any corporate action.

Section 4. Certain Restrictions .

(A) Whenever quarterly dividends or other dividends or distributions payable on the Series A Preferred Shares as provided in Section 2 are in arrears, thereafter and until all accrued and unpaid dividends and distributions, whether or not declared, on Series A Preferred Shares outstanding shall have been paid in full, the Corporation shall not:

(i) declare or pay dividends on, make any other distributions on, or redeem or purchase or otherwise acquire for consideration any shares of capital shares ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series A Preferred Shares;

(ii) declare or pay dividends on or make any other distributions on any shares ranking on a parity (either as to dividends or upon liquidation, dissolution or winding up) with the Series A Preferred Shares, except dividends paid ratably on the Series A Preferred Shares and all such parity shares on which dividends are payable or in arrears in proportion to the total amounts to which the holders of all such shares are then entitled;

A-5

(iii) redeem or purchase or otherwise acquire for consideration shares of any capital shares ranking on a parity (either as to dividends or upon liquidation, dissolution or winding up) with the Series A Preferred Shares, provided that the Corporation may at any time redeem, purchase or otherwise acquire shares of any such parity shares in exchange for shares of any capital shares of the Corporation ranking junior (either as to dividends or upon dissolution, liquidation or winding up) to the Series A Preferred Shares; or

(iv) purchase or otherwise acquire for consideration any Series A Preferred Shares, or any shares of capital shares ranking on a parity with the Series A Preferred Shares, except in accordance with a purchase offer made in writing or by publication (as determined by the Board of Directors) to all holders of such shares upon such terms as the Board of Directors, after consideration of the respective annual dividend rates and other relative rights and preferences of the respective series and classes, shall determine in good faith will result in fair and equitable treatment among the respective series or classes.

(B) The Corporation shall not permit any subsidiary of the Corporation to purchase or otherwise acquire for consideration any shares of the Corporation unless the Corporation could, under paragraph (A) of this Section 4, purchase or otherwise acquire such shares at such time and in such manner.

Section 5. Reacquired Shares .

Any Series A Preferred Shares purchased or otherwise acquired by the Corporation in any manner whatsoever shall be retired and cancelled promptly after the acquisition thereof. All such shares shall upon their cancellation become authorized but unissued Preferred Shares and may be reissued as part of a new series of Preferred Shares to be created by resolution or resolutions of the Board of Directors, subject to the conditions and restrictions on issuance set forth herein.

Section 6. Liquidation, Dissolution or Winding Up .

(A) Upon any liquidation (voluntary or otherwise), dissolution or winding up of the Corporation, no distribution shall be made to the holders of capital shares ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series A Preferred Shares unless, prior thereto, the holders of Series A Preferred Shares shall have received 1,000 per share, plus an amount equal to accrued and unpaid dividends and distributions thereon, whether or not declared, to the date of such payment (the “Series A Liquidation Preference”). Following the payment of the full amount of the Series A Liquidation Preference, no additional distributions shall be made to the holders of Series A Preferred Shares unless, prior thereto, the holders of Common Shares shall have received an amount per share (the “Common Adjustment”) equal to the quotient obtained by dividing (i) the Series A Liquidation Preference by (ii) 1,000 (as appropriately adjusted as set forth in subparagraph (C) below to reflect such events as share splits, share dividends and recapitalizations with respect to the Common Shares) (such number in clause (ii), the “Adjustment Number”). Following the payment of the full

A-6

amount of the Series A Liquidation Preference and the Common Adjustment in respect of all outstanding Series A Preferred Shares and Common Shares, respectively, and the payment of liquidation preferences of all other shares of capital shares which rank prior to or on a parity with Series A Preferred Shares, holders of Series A Preferred Shares and holders of Common Shares shall receive their ratable and proportionate share of the remaining assets to be distributed in the ratio of the Adjustment Number to 1 with respect to such Preferred Shares and Common Shares, on a per share basis, respectively.

(B) In the event, however, that there are not sufficient assets available to permit payment in full of the Series A Liquidation Preference and the liquidation preferences of all other series of Preferred Shares, if any, which rank on a parity with the Series A Preferred Shares, then such remaining assets shall be distributed ratably to the holders of such parity shares in proportion to their respective liquidation preferences. In the event, however, that there are not sufficient assets available to permit payment in full of the Common Adjustment, then such remaining assets shall be distributed ratably to the holders of Common Shares.

(C) In the event the Corporation shall at any time after the Rights Declaration Date (i) declare any dividend on Common Shares payable in Common Shares, (ii) subdivide the outstanding Common Shares, or (iii) combine the outstanding Common Shares into a smaller number of shares, then in each such case the Adjustment Number in effect immediately prior to such event shall be adjusted by multiplying such Adjustment Number by a fraction the numerator of which is the number of Common Shares outstanding immediately after such event and the denominator of which is the number of Common Shares that were outstanding immediately prior to such event.

Section 7. Consolidation, Merger, etc .

In case the Corporation shall enter into any consolidation, merger, combination or other transaction in which the Common Shares are exchanged for or changed into other shares or securities, cash and/or any other property, then in any such case the Series A Preferred Shares shall at the same time be similarly exchanged or changed into an amount per share (subject to the provision for adjustment hereinafter set forth) equal to 1,000 times the aggregate amount of capital shares, securities, cash and/or any other property (payable in kind), as the case may be, for which or into which each Common Share is exchanged or changed. In the event the Corporation shall at any time after the Rights Declaration Date (i) declare any dividend on Common Shares payable in Common Shares, (ii) subdivide the outstanding Common Shares, or (iii) combine the outstanding Common Shares into a smaller number of shares, then in each such case the amount set forth in the preceding sentence with respect to the exchange or change of Series A Preferred Shares shall be adjusted by multiplying such amount by a fraction the numerator of which is the number of Common Shares outstanding immediately after such event and the denominator of which is the number of Common Shares that were outstanding immediately prior to such event.

Section 8. No Redemption .

The Series A Preferred Shares shall not be redeemable.

A-7

Section 9. Ranking .

The Series A Preferred Shares shall rank junior to all other series of the Corporation’s Preferred Shares as to the payment of dividends and the distribution of assets, whether or not upon the dissolution, liquidation or winding up of the Corporation, unless the terms of any such series shall provide otherwise.

Section 10. Amendment .

The Charter shall not be amended in any manner which would materially alter or change the powers, preferences or special rights of the Series A Preferred Shares so as to affect them adversely without the affirmative vote of the holders of a majority of the outstanding Series A Preferred Shares, voting separately as a class.

Section 11. Fractional Shares .

Series A Preferred Shares may be issued in fractions of a share which shall entitle the holder, in proportion to such holder’s fractional shares, to exercise voting rights, receive dividends, participate in distributions and to have the benefit of all other rights of holders of Series A Preferred Shares.

Rights Certificate

PULTEGROUP, INC.

This certifies that                      , or registered assigns, is the registered owner of the number of Rights set forth above, each of which entitles the owner thereof, subject to the terms, provisions and conditions of the Amended and Restated Section 382 Rights Agreement, dated as of March 5, 2009 (the “Rights Agreement”), between PulteGroup, Inc., a Michigan corporation (the “Company”), and Computershare Trust Company, N.A., a federally chartered trust company (the “Rights Agent”), to purchase from the Company at any time prior to the Expiration Date (as defined in the Rights Agreement) at the office or offices of the Rights Agent designated for such purpose, or its successors as Rights Agent, one one-thousandth of a fully paid, nonassessable Series A Junior Participating Preferred Share, par value $0.01 per share (the “Preferred Shares”), of the Company, at a purchase price of $          per one one-thousandth of a share (the “Purchase Price”), upon presentation and surrender of this Rights Certificate with the Form of Election to Purchase and related Certificate duly executed. The number of Rights evidenced by this Rights Certificate (and the number of shares which may be purchased upon exercise thereof) set forth above, and the Purchase Price per share set forth above, are the number and Purchase Price as of               , 20      , based on the Preferred Shares as constituted at such date. The Company reserves the right to require prior to the occurrence of a Section 11(a)(ii) Event (as defined in the Rights Agreement) that, upon any exercise of Rights, a number of Rights be exercised so that only whole Preferred Shares will be issued.

Upon the occurrence of a Section 11(a)(ii) Event (as defined in the Rights Agreement), if the Rights evidenced by this Rights Certificate are beneficially owned by (i) an Acquiring Person (as defined in the Rights Agreement), (ii) a transferee of any such Acquiring Person who becomes a transferee after the Acquiring Person becomes such, or (iii) under certain circumstances specified in the Rights Agreement, a transferee of an Acquiring Person who becomes a transferee prior to or concurrently with the Acquiring Person becoming such, such Rights shall become null and void and no holder hereof shall have any right with respect to such Rights from and after the occurrence of such Section 11(a)(ii) Event.

As provided in the Rights Agreement, the Purchase Price and the number and kind of Preferred Shares or other securities which may be purchased upon the exercise of the Rights evidenced by this Rights Certificate are subject to modification and adjustment upon the happening of certain events, including, without limitation, a Section 11(a)(ii) Event.

This Rights Certificate is subject to all of the terms, provisions and conditions of the Rights Agreement, which terms, provisions and conditions are hereby incorporated herein by reference and made a part hereof and to which Rights Agreement reference is hereby made for a full description of the rights, limitations of rights, obligations, duties and immunities hereunder of the Rights Agent, the Company and the holders of the Rights Certificates, which limitations of rights include, without limitation, the temporary suspension of the exercisability of such Rights under the specific circumstances set forth in the Rights Agreement. Copies of the Rights Agreement are on file at the office of the Company and are also available upon written request to the Company.

This Rights Certificate, with or without other Rights Certificates, upon surrender at the principal office or offices of the Rights Agent designated for such purpose, may be exchanged for another Rights Certificate or Rights Certificates of like tenor and date evidencing Rights entitling the holder to purchase a like aggregate number of one one-thousandths of a Preferred Share as the Rights evidenced by the Rights Certificates surrendered shall have entitled such holder to purchase. If this Rights Certificate shall be exercised in part, the holder shall be entitled to receive upon surrender hereof another Rights Certificate or Rights Certificates for the number of whole Rights not exercised.

Subject to the provisions of the Rights Agreement, the Rights evidenced by this Certificate may, in each case at the option of the Company, be (i) redeemed by the Company at its option at a redemption price of $0.001 per Right or (ii) exchanged in whole or in part for Common Shares or other securities of the Company. Immediately upon the action of the Board of Directors of the Company authorizing redemption, the Rights will terminate and the only right of the holders of Rights will be to receive the redemption price.

No fractional Preferred Shares will be issued upon the exercise of any Right or Rights evidenced hereby (other than fractions which are integral multiples of one one-thousandth of a Preferred Share, which may, at the election of the Company, be evidenced by depositary receipts), but in lieu thereof a cash payment will be made, as provided in the Rights Agreement.

No holder of this Rights Certificate shall be entitled to vote or receive dividends or be deemed for any purpose the holder of Preferred Shares or of any other securities of the Company which may at any time be issuable on the exercise hereof, nor shall anything contained in the Rights Agreement or herein be construed to confer upon the holder hereof, as such, any of the rights of a shareholder of the Company or any right to vote for the election of directors or upon any matter submitted to shareholders at any meeting thereof, or to give or withhold consent to any corporate action, or, to receive notice of meetings or other actions affecting shareholders (except as provided in the Rights Agreement), or to receive dividends or subscription rights, or otherwise, until the Right or Rights evidenced by this Rights Certificate shall have been exercised as provided in the Rights Agreement.

This Rights Certificate shall not be valid or obligatory for any purpose until it shall have been countersigned manually or by facsimile signature by the Rights Agent.

Exhibit C

SUMMARY OF RIGHTS TO PURCHASE PREFERRED SHARES

On March 18, 2010, the board of directors of PulteGroup, Inc. (“PHM”) entered into an Amended and Restated Section 382 Rights Agreement (the “Amended and Restated Section 382 Rights Agreement”) with Computershare Trust Company, N.A., as rights agent. The board of directors of PHM had previously declared a dividend distribution of one right for each outstanding common share to shareholders of record at the close of business on March 16, 2009, pursuant to that certain Section 382 Rights Agreement, dated as of March 5, 2009, as amended as of April 7, 2009 and as of September 24, 2009 (collectively, the “Original Section 382 Rights Agreement”), between the Company and the Rights Agent. The Amended and Restated Section 382 Rights Agreement (the “rights plan”) restated the Original Section 382 Rights Agreement and revised the definitions of “Affiliate” and “Associate” to delete references to the Exchange Act.

The PHM board of directors adopted the rights plan in an effort to protect shareholder value by attempting to protect against a possible limitation on PHM’s ability to use its net operating loss carryforwards (the “NOLs”) and certain other tax benefits to reduce potential future U.S. federal income tax obligations. If PHM experiences an “ownership change,” as defined in Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”), and the regulations promulgated by the United States Department of the Treasury thereunder (the “related Treasury regulations”), its ability to fully utilize the NOLs and certain other tax benefits on an annual basis will be substantially limited, and the timing of the usage of the NOLs and such other benefits could be substantially delayed, which could therefore significantly impair the value of those assets.

The rights plan is intended to act as a deterrent to any person or group, together with its affiliates and associates, being or becoming the beneficial owner of 4.9% or more of PHM securities (such person or group is referred to as an “acquiring person”). A person shall be deemed to be a “beneficial owner” of, or shall be deemed to have “beneficial ownership” and shall be deemed to “beneficially own” any securities which such person directly owns, or would be deemed to constructively own, pursuant to Section 382 and the related Treasury regulations. The term “acquiring person” does not include:

C-1

A shareholder who together with its affiliates and associates beneficially owned 4.9% or more of PHM securities as of March 5, 2009 is deemed not to be an “acquiring person,” so long as such shareholder does not acquire any additional shares of PHM securities without the prior written approval of PHM, other than pursuant to or as a result of (a) a reduction in the amount of PHM securities outstanding; (b) the exercise of any options, warrants, rights or similar interests to purchase PHM securities granted by PHM to its directors, officers and employees; (c) any unilateral grant of any PHM securities by PHM or (d) any issuance of PHM securities by PHM or any share dividend, share split or similar transaction effected by PHM in which all holders of PHM securities are treated equally. Such a shareholder is a “grandfathered person” for purposes of the rights plan.

The board of directors of PHM may, in its sole discretion, exempt any person or group who would otherwise be an acquiring person from being deemed an acquiring person for purposes of the rights plan if it determines at any time prior to the time at which the rights are no longer redeemable that the beneficial ownership of such Person would not jeopardize, endanger or limit (in timing or amount) the availability of PHM’s NOLs and other tax benefits. Any such person or group is an “exempted person” under the rights plan. The board of directors, in its sole discretion, may subsequently make a contrary determination and such person would then become an acquiring person.

C-2

An “exempted transaction” is a transaction that the board of directors determines is an exempted transaction and, unlike the determination of an exempted person, such determination is irrevocable.

The Rights . Each right entitles its holder, under the circumstances described below, to purchase from PHM one one-thousandth of a PHM Series A Junior Participating Preferred Share at a purchase price of $50 per right, subject to adjustment. PHM common shares issued while the Section 382 rights plan is in effect will be issued with rights attached.

Initially, the rights will be associated with PHM common shares and evidenced by common share certificates, which will contain a notation incorporating the rights plan by reference, and will be transferable with and only with the underlying PHM common shares. Subject to certain exceptions, the rights become exercisable and trade separately from the PHM common shares only upon the “distribution date,” which occurs upon the earlier of:

Until the distribution date, the surrender for transfer of any PHM common shares outstanding will also constitute the transfer of the rights associated with those shares.

As soon as practicable after the distribution date, separate certificates or book-entry statements will be mailed to holders of record of PHM common shares as of the close of business on the distribution date. From and after the distribution date, the separate rights certificates or book-entry statements alone will represent the rights. Except as otherwise provided in the rights plan, only PHM common shares issued prior to the distribution date will be issued with rights.

Expiration . The rights are not exercisable until the distribution date and, unless earlier redeemed or exchanged by PHM as described below, will expire upon the earliest of:

C-3

Effects of Triggering Event . If a person or group becomes an acquiring person (a “flip-in event”), each holder of a right (other than any acquiring person and certain transferees of an acquiring person, whose rights automatically become null and void) will have the right to receive, upon exercise, PHM common shares having a value equal to two times the exercise price of the right. If an insufficient number of PHM common shares are available for issuance, then the PHM board of directors is required to substitute cash, property or other securities of PHM for the PHM common shares. The rights may not be exercised following a flip-in event while PHM has the ability to cause the rights to be redeemed, as described below.

For example, at an exercise price of $50 per right, each right not owned by an acquiring person (or by certain transferees thereof) following a flip-in event would entitle its holder to purchase $100 worth of PHM common shares (or other consideration, as noted above) for $50. Assuming that the PHM common shares had a per share value of $10 at that time, the holder of each valid right would be entitled to purchase ten PHM common shares for $50.

Exchange . At any time after there is an acquiring person and prior to the acquisition by the acquiring person of 50% or more of the outstanding PHM common shares, PHM may exchange the rights (other than rights owned by the acquiring person and certain transferees thereof which will have become void), in whole or in part, at an exchange ratio of one PHM common share, or one one-thousandth of a PHM preferred share (or of a share of a class or series of PHM preferred shares having equivalent rights, preferences and privileges), per right (subject to adjustment).

Adjustments . The exercise price payable, and the number of preferred shares or other securities or property issuable, upon exercise of the rights are subject to adjustment from time to time to prevent dilution:

C-4

With certain exceptions, no adjustment in the exercise price will be required until cumulative adjustments amount to at least 1% of the exercise price. No fractional preferred shares will be issued, and, in lieu thereof, an adjustment in cash will be made based on the market price of the preferred shares on the last trading day prior to the date of exercise.

Redemption . In general, PHM may redeem the rights in whole, but not in part, at a price of $0.001 per right (subject to adjustment and payable in cash, PHM common shares or other consideration deemed appropriate by the PHM board of directors) at any time until ten days following the share acquisition date. Immediately upon the action of the PHM board of directors authorizing any redemption, the rights will terminate, and the only right of the holders of rights will be to receive the redemption price.

Shareholder Rights; Tax Effects . Until a right is exercised, its holder will have no rights as a shareholder of PHM, including, without limitation, the right to vote or to receive dividends. While the distribution of the rights will not result in the recognition of taxable income by PHM or its shareholders, shareholders may, depending upon the circumstances, recognize taxable income after a flip-in event.

Amendment . The terms of the rights may be amended by the PHM board of directors without the consent of the holders of the rights, including, without limitation, to extend the expiration date of the rights plan and to increase or decrease the purchase price. Once there is an acquiring person, however, no amendment can adversely affect the interests of the holders of the rights.

A copy of the rights plan is available free of charge from PHM. This description of the rights does not purport to be complete and is qualified in its entirety by reference to the rights plan, which is incorporated herein by reference.
