WITNESSETH:

WHEREAS, the Board of Directors of the Company has (a) authorized and declared a dividend of one right (“Right”) in respect of each share of Common Stock (as hereinafter defined) held of record as of the Close of Business on September 25, 2007 (the “Record Time”) and (b) as provided in Section 2.3, authorized the issuance of one Right in respect of each share of Common Stock issued on or after the date hereof and prior to the Separation Time (as hereinafter defined) and, to the extent provided in Section 5.3, each share of Common Stock issued after the Separation Time;

WHEREAS, subject to the terms and conditions hereof, each Right entitles the holder thereof, after the Separation Time, to purchase securities or assets of the Company (or, in certain cases, securities of certain other entities) pursuant to the terms and subject to the conditions set forth herein; and

WHEREAS, the Company desires to appoint the Rights Agent to act on behalf of the Company, and the Rights Agent is willing so to act, in connection with the issuance, transfer, exchange and replacement of Rights Certificates (as hereinafter defined), the exercise of Rights and other matters referred to herein;

NOW THEREFORE, in consideration of the premises and the respective agreements set forth herein, the parties hereby agree as follows:

ARTICLE I

CERTAIN DEFINITIONS

1.1 Certain Definitions. For purposes of this Agreement, the following terms have the meanings indicated:

“Acquiring Person” shall mean any Person, together with all Affiliates and Associates of such Person, who is or becomes the Beneficial Owner of 15% or more of the outstanding shares of Common Stock; provided, however, that the term “Acquiring Person” shall not include (i) Acuity Brands, Inc., a Delaware corporation (“Old Parent”), until the effective date of the merger (the “Holding Company Merger”) of a wholly owned Subsidiary of the Company (“Merger Sub”) with and into Old Parent as contemplated by the Agreement and Plan of Merger among Old Parent, Merger Sub and the Company; (ii) any Person who is the Beneficial Owner of 15% or more of the outstanding shares of Common Stock on the date of this Agreement or who shall become the Beneficial Owner of 15% or more of the outstanding shares of Common Stock solely as a result of an acquisition by the Company of shares of Common Stock, until such time hereafter or thereafter as any of such Persons shall become the Beneficial Owner (other than by means of a stock dividend or stock split) of any additional shares of Common Stock, or (iii) any Person who becomes the Beneficial Owner of 15% or more of the outstanding shares of Common Stock but who acquired Beneficial Ownership of shares of Common Stock without any plan or intention to seek or affect control of the Company, if such Person promptly divests, or enters into an agreement with the Company satisfactory to the Company, in its sole discretion, to divest, and thereafter promptly divests (without exercising or retaining any power, including voting power, with respect to such shares), sufficient shares of Common Stock (or securities convertible into, exchangeable into or exercisable for Common

-2-

Stock) so that such Person ceases to be the Beneficial Owner of 15% or more of the outstanding shares of Common Stock. In addition, the Company, any Subsidiary of the Company and any employee stock ownership or other employee benefit plan of the Company or a Subsidiary of the Company (or any entity or trustee holding shares of Common Stock for or pursuant to the terms of any such plan or for the purpose of funding any such plan or funding other employee benefits for employees of the Company or of any Subsidiary of the Company) or any Person organized, appointed or established by the Company for or pursuant to the terms of any such plan shall not be an Acquiring Person.

“Affiliate” and “Associate” shall have the respective meanings ascribed to such terms in Rule 12b-2 under the Exchange Act, as such Rule is amended and in effect on the date of this Agreement.

A Person shall be deemed the “Beneficial Owner”, and to have “Beneficial Ownership” of, and to “Beneficially Own”, any securities as to which such Person or any of such Person’s Affiliates or Associates is or may be deemed to be the beneficial owner of pursuant to Rule 13d-3 and Rule 13d-5 under the Exchange Act, as such Rules are amended and in effect on the date of this Agreement, as well as any securities as to which such Person or any of such Person’s Affiliates or Associates, directly or indirectly, has the right to become Beneficial Owner (whether such right is exercisable immediately or only after the passage of time or the occurrence of conditions) pursuant to any agreement, arrangement or understanding (other than customary agreements with and between underwriters and selling group members with respect to a bona fide public offering of securities), or upon the exercise of conversion rights, exchange rights, rights (other than the Rights), warrants or options, or otherwise; provided, however, that a Person shall not be deemed the “Beneficial Owner”, or to have “Beneficial Ownership” of, or to

-3-

“Beneficially Own”, any security (i) solely because such security has been tendered pursuant to a tender or exchange offer made by such Person or any of such Person’s Affiliates or Associates until such tendered security is accepted for payment or exchange or (ii) solely because such Person or any of such Person’s Affiliates or Associates has or shares the power to vote or direct the voting of such security pursuant to a revocable proxy given in response to a public proxy or consent solicitation made to more than ten holders of shares of a class of stock of the Company registered under Section 12 of the Exchange Act and pursuant to, and in accordance with, the applicable rules and regulations under the Exchange Act, except if such power (or the agreements, arrangements or understandings relating thereto) is then reportable under Item 6 of Schedule 13D under the Exchange Act (or any similar provision of a comparable or successor report). For purposes of this Agreement, in determining the percentage of the outstanding shares of Common Stock with respect to which a Person is the Beneficial Owner, all shares as to which such Person is deemed the Beneficial Owner shall be deemed outstanding.

“Flip-in Date” shall mean any Stock Acquisition Date or such later date and time as the Board of Directors of the Company may from time to time fix by resolution adopted prior to the Flip-in Date that would otherwise have occurred.

“Flip-over Entity,” for purposes of Section 3.2, shall mean (i) in the case of a Flip-over Transaction or Event described in clause (i) of the definition thereof, the Person issuing any securities into which shares of Common Stock are being converted or exchanged and, if no such securities are being issued, the other party to such Flip-over Transaction or Event and (ii) in the case of a Flip-over Transaction or Event referred to in clause (ii) of the definition thereof, the Person receiving the greatest portion of the assets, operating income or cash flow being transferred in such Flip-over Transaction or Event, provided in all cases if such Person is a Subsidiary of a Person, the parent Person shall be the Flip-Over Entity.

“Holding Company Merger” shall have the meaning ascribed to such term in the definition hereunder of “Acquiring Person.”

“Market Price” per share of any securities on any date shall mean the average of the daily closing prices per share of such securities (determined as described below) on each of the 20 consecutive Trading Days through and including the Trading Day immediately preceding such date; provided, however, that if any event described in Section 2.3 hereof, or any analogous event, shall have caused the closing prices used to determine the Market Price on any Trading Days during such period of 20 Trading Days not to be fully comparable with the closing price on such date, each such closing price so used shall be appropriately adjusted in order to make it fully comparable with the closing price on such date. The closing price per share of any

-6-

securities on any date shall be the last reported sale price, regular way, or, in case no such sale takes place or is quoted on such date, the average of the closing bid and asked prices, regular way, for each share of such securities, 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, Inc. or, if the securities are not listed or admitted to trading on the New York Stock Exchange, Inc., as reported in the principal consolidated transaction reporting system with respect to securities listed on the principal national securities exchange on which the securities are listed or admitted to trading or, if the securities are not listed or admitted to trading on any national securities exchange, as reported by the National Association of Securities Dealers, Inc.

THE RIGHTS

2.1 Legend on Common Stock Certificates. Certificates for the Common Stock issued on or after the date of this Agreement but prior to the Separation Time shall evidence one Right for each share of Common Stock represented thereby and, except for certificates for the Common Stock issued in connection with the Holding Company Merger (which certificates previously represented common stock of Old Parent), shall have impressed on, printed on, written on or otherwise affixed to them a legend in substantially the following form:

Until the Separation Time (as defined in the Rights Agreement referred to below), this certificate also evidences and entitles the holder hereof to certain Rights as set forth in a Stockholder Protection Rights Agreement, dated as of September 25, 2007 (as such may be amended from time to time, the “Rights Agreement”), between Acuity Brands

-9-

Holdings, Inc. (the “Company”) and The Bank of New York, as Rights Agent, the terms of which are hereby incorporated herein by reference and a copy of which is on file at the principal executive offices of the Company. Under certain circumstances, as set forth in the Rights Agreement, such Rights may be redeemed, may become exercisable for securities or assets of the Company or securities of another entity, may be exchanged for shares of Common Stock or other securities or assets of the Company, may expire, may become null and void (if they are “Beneficially Owned” by an “Acquiring Person” or an “Affiliate” or “Associate” thereof, as such terms are defined in the Rights Agreement, or by any transferee of any of the foregoing) or may be evidenced by separate certificates and may no longer be evidenced by this certificate. The Company will mail or arrange for the mailing of a copy of the Rights Agreement to the holder of this certificate without charge after the receipt of a written request therefor.

Certificates representing shares of Common Stock that are issued and outstanding at the Record Time shall evidence one Right for each share of Common Stock evidenced thereby notwithstanding the absence of the foregoing legend.

If the Common Stock issued after the Record Time but prior to the Separation Time shall be uncertificated, the registration of such Common Stock on the stock transfer books of the Company shall evidence one Right for each share of Common Stock represented thereby and the Company will mail to every Person that holds such Common Stock a confirmation of the registration of such Common Stock on the stock transfer books of the Company, which confirmation will have impressed, printed, written or stamped thereon or otherwise affixed thereto the above legend or such other notification as to which the Company and the Rights Agent shall mutually agree. The Company will mail or arrange for the mailing of a copy of this Agreement to any Person that holds Common Stock, as evidenced by the registration of the Common Stock in the name of such Person on the stock transfer books of the Company, without charge after the receipt of a written request therefor from such Person.

2.2 Exercise of Rights; Separation of Rights. (a) Subject to Sections 3.1, 3.2, 5.1 and 5.10 and subject to adjustment as herein set forth, each Right will entitle the holder thereof, on or after the Separation Time and prior to the Expiration Time, to purchase, for the Exercise Price, one one-hundredth of a share of Preferred Stock.

-10-

(b) Until the Separation Time, (i) no Right may be exercised and (ii) each Right will be evidenced by the certificate for the associated share of Common Stock (or, if the Common Stock shall be uncertificated, by the registration of the associated Common Stock on the stock transfer books of the Company) and will be transferable only together with, and will be transferred by a transfer of, such associated share.

(c) Subject to the terms and conditions hereof, on or after the Separation Time and prior to the Expiration Time, the Rights (i) may be exercised and (ii) may be transferred independent of shares of Common Stock. Promptly following the Separation Time and receipt by the Rights Agent of notice thereof as well as other relevant information, the Rights Agent will mail to each holder of record of Common Stock as of the Separation Time (other than any Person whose Rights have become null and void pursuant to Section 3.1(b)), at such holder’s address as shown by the records of the Company (the Company hereby agreeing to furnish, or causing to be furnished, copies of such records to the Rights Agent for this purpose), (x) a certificate (a “Rights Certificate”) in substantially the form of Exhibit A hereto appropriately completed, representing the number of Rights held by such holder at the Separation Time and having such marks of identification or designation and such legends, summaries or endorsements printed thereon as the Company may deem appropriate (but which do not affect the rights, duties, liabilities or responsibilities of the Rights Agent) and as are not inconsistent with the provisions of this Agreement, or as may be required to comply with any law or with any rule or regulation made pursuant thereto or with any rule or regulation of any national securities exchange or quotation system on which the Rights may from time to time be listed or traded, or to conform to usage, and (y) a disclosure statement describing the Rights.

-11-

(d) Subject to the terms and conditions hereof, Rights may be exercised on any Business Day on or after the Separation Time and prior to the Expiration Time by submitting to the Rights Agent the Rights Certificate evidencing such Rights with an Election to Exercise (an “Election to Exercise”) substantially in the form attached to the Rights Certificate duly and properly completed, accompanied by payment in cash, or by certified or official bank check or money order payable to the order of the Company, of a sum equal to the Exercise Price multiplied by the number of Rights being exercised and a sum sufficient to cover any tax or charge which may be payable in respect of any transfer involved in the transfer or delivery of Rights Certificates or the issuance or delivery of certificates (or, if uncertificated, the registration on the stock transfer books of the Company) for shares or depositary receipts (or both) in a name other than that of the holder of the Rights being exercised.

(e) Upon receipt of a Rights Certificate, with an Election to Exercise duly and properly completed accompanied by payment as set forth in Section 2.2(d), and subject to the terms and conditions hereof, the Rights Agent will thereupon promptly (i)(A) requisition from the transfer agent of the Company stock certificates evidencing such number of shares or other securities to be purchased or, in the case of uncertificated shares or other securities, requisition from the transfer agent of the Company a notice setting forth such number of shares or other securities to be purchased for which registration will be made on the stock transfer books of the Company (the Company hereby irrevocably authorizing its transfer agents to comply with all such requisitions) and (B) if the Company elects pursuant to Section 5.5 not to issue certificates (or effect registration on the stock transfer books of the Company) representing fractional shares,

-12-

requisition from the depositary selected by the Company depositary receipts representing the fractional shares to be purchased or requisition from the Company the amount of cash to be paid in lieu of fractional shares in accordance with Section 5.5 and (ii) after receipt of such certificates, depositary receipts, notices and/or cash, deliver the same to or upon the order of the registered holder of such Rights Certificate, registered (in the case of certificates, depositary receipts or notices) in such name or names as may be designated by such holder.

(f) In case the holder of any Rights shall exercise less than all the Rights evidenced by such holder’s Rights Certificate, a new Rights Certificate evidencing the Rights remaining unexercised will be issued by the Rights Agent to such holder or to such holder’s duly authorized assigns.

(g) The Company covenants and agrees that it will (i) take all such action as may be necessary to ensure that all shares delivered (or evidenced by registration on the stock transfer books of the Company) upon exercise of Rights shall, at the time of delivery of the certificates (or registration) for such shares (subject to payment of the Exercise Price), be duly and validly authorized, executed, issued and delivered (or registered) and fully paid and nonassessable; (ii) take all such action as may be necessary to comply with any applicable requirements of the Securities Act of 1933, as amended, or the Exchange Act, and the rules and regulations thereunder, and any other applicable law, rule or regulation, in connection with the issuance of any securities upon exercise of Rights; and (iii) pay when due and payable any and all federal and state taxes and governmental charges which may be payable in respect of the original issuance or delivery of the Rights Certificates or of any shares issued upon the exercise of Rights, provided, that the Company shall not be required to pay any tax or charge which may be payable in respect of any transfer involved in the transfer or delivery of Rights Certificates or the issuance or delivery of certificates (or the registration) for shares in a name other than that of the holder of the Rights being transferred or exercised.

-13-

2.3 Adjustments to Exercise Price; Number of Rights. (a) In the event the Company shall at any time after the Record Time and prior to the Separation Time (i) declare or pay a dividend on Common Stock payable in Common Stock, (ii) subdivide the outstanding Common Stock or (iii) combine the outstanding Common Stock into a smaller number of shares of Common Stock, (x) the Exercise Price in effect after such adjustment will be equal to the Exercise Price in effect immediately prior to such adjustment divided by the number of shares of Common Stock (the “Expansion Factor”) that a holder of one share of Common Stock immediately prior to such dividend, subdivision or combination would hold thereafter as a result thereof and (y) each Right held prior to such adjustment will become that number of Rights equal to the Expansion Factor, and the adjusted number of Rights will be deemed to be distributed among the shares of Common Stock with respect to which the original Rights were associated (if they remain outstanding) and the shares issued in respect of such dividend, subdivision or combination, so that each such share of Common Stock will have exactly one Right associated with it. Each adjustment made pursuant to this paragraph shall be made as of the payment or effective date for the applicable dividend, subdivision or combination.

In the event the Company shall at any time after the Record Time and prior to the Separation Time issue any shares of Common Stock otherwise than in a transaction referred to in the preceding paragraph, each such share of Common Stock so issued shall automatically have one new Right associated with it, which Right shall be evidenced by the certificate representing such share (or, if the Common Stock shall be uncertificated, such Right shall be evidenced by the registration of such Common Stock on the stock transfer books of the Company). Rights shall be issued by the Company in respect of shares of Common Stock that are issued or sold by the Company after the Separation Time only to the extent provided in Section 5.3.

-14-

(b) In the event the Company shall at any time after the Record Time and prior to the Separation Time issue or distribute any securities or assets in respect of, in lieu of or in exchange for Common Stock (other than pursuant to any non-extraordinary periodic cash dividend or a dividend paid solely in Common Stock) whether by dividend, in a reclassification or recapitalization (including any such transaction involving a merger, consolidation or share exchange), or otherwise, the Company shall make such adjustments, if any, in the Exercise Price, number of Rights and/or securities or other property purchasable upon exercise of Rights as the Board of Directors of the Company, in its sole discretion, may deem to be appropriate under the circumstances in order to adequately protect the interests of the holders of Rights generally, and the Company and the Rights Agent, subject to Section 5.4, shall amend this Agreement as necessary to provide for such adjustments.

(c) Each adjustment to the Exercise Price made pursuant to this Section 2.3 shall be calculated to the nearest cent. Whenever an adjustment to the Exercise Price is made pursuant to this Section 2.3 or any event affecting the Rights or their exercisability (including, without limitation, an event which causes the Rights to become null and void), the Company shall (i) promptly prepare a certificate setting forth such adjustment or describing such event and a brief, reasonably detailed statement of the facts, computations and methodology accounting for such adjustment and (ii) promptly file with the Rights Agent and with each transfer agent for the Common Stock a copy of such certificate. The Rights Agent shall be fully protected in relying on such certificate and on any adjustment therein contained and shall have no duty with respect to and shall not be deemed to have knowledge of any adjustment unless and until it shall have received such a certificate.

-15-

(d) Rights certificates shall represent the securities purchasable under the terms of this Agreement, including any adjustment or change in the securities purchasable upon exercise of the Rights, even though such certificates may continue to express the securities purchasable at the time of issuance of the initial Rights Certificates.

2.4 Date on Which Exercise is Effective. Each Person in whose name any certificate for shares is issued (or registration on the stock transfer books of the Company is effected) upon the exercise of Rights shall for all purposes be deemed to have become the holder of record of the shares represented thereby on the date upon which the Rights Certificate evidencing such Rights was duly surrendered and payment of the Exercise Price for such Rights (and any applicable taxes and other governmental charges payable by the exercising holder hereunder) was made; provided, however, that if the date of such surrender and payment is a date upon which the stock transfer books of the Company are closed, such Person shall be deemed to have become the record holder of such shares on, and such certificate (or registration) shall be dated, the next succeeding Business Day on which the stock transfer books of the Company are open.

2.5 Execution, Authentication, Delivery and Dating of Rights Certificates. (a) The Rights Certificates shall be executed on behalf of the Company by its Chairman of the Board, Chief Executive Officer, President, Treasurer, Chief Operating Officer or one of its Vice Presidents, under its corporate seal reproduced thereon attested by its Secretary or one of its Assistant Secretaries. The signature of any of these officers on the Rights Certificates may be manual or facsimile.

-16-

Rights Certificates bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the countersignature and delivery of such Rights Certificates.

Promptly after the Separation Time, the Company will give written notice to the Rights Agent of such Separation Time and will deliver Rights Certificates executed by the Company to the Rights Agent for counter-signature, and, subject to Section 3.1(b), the Rights Agent shall countersign and deliver such Rights Certificates to the holders of the Rights pursuant to Section 2.2(c) hereof. Until such notice is received by the Rights Agent, the Rights Agent may presume conclusively that the Separation Time has not occurred. No Rights Certificate shall be valid for any purpose unless countersigned by the Rights Agent. The countersignature of the Rights Agent on the Rights Certificates must be manual.

(b) Each Rights Certificate shall be dated the date of countersignature thereof.

2.6 Registration, Registration of Transfer and Exchange. (a) After the Separation Time, the Company will cause to be kept a register (the “Rights Register”) in which, subject to such reasonable regulations as it may prescribe, the Company will provide for the registration and transfer of Rights. The Rights Agent is hereby appointed “Rights Registrar” for the purpose of maintaining the Rights Register for the Company and registering Rights and transfers of Rights after the Separation Time as herein provided. In the event that the Rights Agent shall cease to be the Rights Registrar, the Rights Agent will have the right to examine the Rights Register at all reasonable times after the Separation Time.

After the Separation Time and prior to the Expiration Time, upon surrender for registration of transfer or exchange of any Rights Certificate, and subject to the provisions of

-17-

Section 2.6(c) and (d), the Company will execute, and the Rights Agent will countersign and deliver, in the name of the holder or the designated transferee or transferees, as required pursuant to the holder’s instructions, one or more new Rights Certificates evidencing the same aggregate number of Rights as did the Rights Certificate so surrendered.

(b) Except as otherwise provided in Section 3.1(b), all Rights issued upon any registration of transfer or exchange of Rights Certificates shall be the valid obligations of the Company, and such Rights shall be entitled to the same benefits under this Agreement as the Rights surrendered upon such registration of transfer or exchange.

(c) Every Rights Certificate surrendered for registration of transfer or exchange shall be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company or the Rights Agent, as the case may be, duly executed by the holder thereof or such holder’s attorney duly authorized in writing. As a condition to the issuance of any new Rights Certificate under this Section 2.6, the Company or the Rights Agent may require the payment of a sum sufficient to cover any tax or other charge that may be imposed in relation thereto. The Rights Agent shall have no duty or obligation to take any action under any Section of this Agreement which requires the payment of a Rights holder of applicable taxes and changes unless and until the Rights Agent is satisfied that all such taxes and/or charges have been paid.

(d) The Company shall not register the transfer or exchange of any Rights after such Rights have become null and void under Section 3.1(b), been exchanged under Section 3.1(c) or been redeemed under Section 5.1.

2.7 Mutilated, Destroyed, Lost and Stolen Rights Certificates. (a) If any mutilated Rights Certificate is surrendered to the Rights Agent prior to the Expiration Time, then, subject to Sections 3.1(b), 3.1(c) and 5.1, the Company shall execute and the Rights Agent shall countersign and deliver in exchange therefor a new Rights Certificate evidencing the same number of Rights as did the Rights Certificate so surrendered.

(b) If there shall be delivered to the Company and the Rights Agent prior to the Expiration Time (i) evidence to their satisfaction of the destruction, loss or theft of any Rights Certificate and (ii) such security or indemnity as may be required by them to save each of them and any of their agents harmless, then, subject to Sections 3.1(b), 3.1(c) and 5.1 and in the absence of notice to the Company or the Rights Agent that such Rights Certificate has been acquired by a bona fide purchaser, the Company shall execute and upon its request the Rights Agent shall countersign and deliver, in lieu of any such destroyed, lost or stolen Rights Certificate, a new Rights Certificate evidencing the same number of Rights as did the Rights Certificate so destroyed, lost or stolen.

(c) As a condition to the issuance of any new Rights Certificate under this Section 2.7, the Company may require the payment of a sum sufficient to cover any tax or other charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Rights Agent) connected therewith.

(d) Every new Rights Certificate issued pursuant to this Section 2.7 in lieu of any destroyed, lost or stolen Rights Certificate shall evidence an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Rights Certificate shall be at any time enforceable by anyone, and, subject to Section 3.1(b) shall be entitled to all the benefits of this Agreement equally and proportionately with any and all other Rights duly issued hereunder.

2.8 Persons Deemed Owners. Prior to due presentment of a Rights Certificate (or, prior to the Separation Time, the associated Common Stock certificate or notice of transfer,

-19-

if uncertificated) for registration of transfer, the Company, the Rights Agent and any agent of the Company or the Rights Agent may deem and treat the Person in whose name such Rights Certificate (or, prior to the Separation Time, such Common Stock certificate or Common Stock registration, if uncertificated) is registered as the absolute owner thereof and of the Rights evidenced thereby for all purposes whatsoever, including the payment of the Redemption Price and neither the Company nor the Rights Agent shall be affected by any notice to the contrary. As used in this Agreement, unless the context otherwise requires, the term “holder” of any Rights shall mean the registered holder of such Rights (or, prior to the Separation Time, the associated shares of Common Stock).

2.9 Delivery, Cancellation and Destruction of Certificates. All Rights Certificates surrendered upon exercise or for registration of transfer or exchange shall, if surrendered to any Person other than the Rights Agent, be delivered to the Rights Agent and, in any case, shall be promptly canceled by the Rights Agent. The Company may at any time deliver to the Rights Agent for cancellation any Rights Certificates previously countersigned and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Rights Certificates so delivered shall be promptly canceled by the Rights Agent. No Rights Certificates shall be countersigned in lieu of or in exchange for any Rights Certificates canceled as provided in this Section 2.9, except as expressly permitted by this Agreement. The Rights Agent shall return to the Company all canceled Rights Certificates approximately one and one-half (1 1/2) years after the cancellation date. The Company shall destroy the certificates after any applicable retention period required by the United States Securities and Exchange Commission.

-20-

2.10 Agreement of Rights Holders. Every holder of Rights by accepting the same consents and agrees with the Company and the Rights Agent and with every other holder of Rights that:

(a) prior to the Separation Time, each Right will be transferable only together with, and will be transferred by a transfer of, the associated share of Common Stock;

(b) after the Separation Time, the Rights Certificates will be transferable only on the Rights Register as provided herein;

(c) prior to due presentment of a Rights Certificate (or, prior to the Separation Time, the associated Common Stock certificate or Common Stock registration, if uncertificated) for registration of transfer, the Company, the Rights Agent and any agent of the Company or the Rights Agent may deem and treat the Person in whose name the Rights Certificate (or, prior to the Separation Time, the associated Common Stock certificate or Common Stock registration, if uncertificated) is registered as the absolute owner thereof and of the Rights evidenced thereby for all purposes whatsoever, and neither the Company nor the Rights Agent shall be affected by any notice to the contrary;

(d) Rights beneficially owned by certain Persons will, under the circumstances set forth in Section 3.1(b), become null and void; and

(e) this Agreement may be supplemented or amended from time to time pursuant to Section 2.3(b) or 5.4 hereof.

ARTICLE III

ADJUSTMENTS TO THE RIGHTS IN

THE EVENT OF CERTAIN TRANSACTIONS

3.1 Flip-in. (a) In the event that prior to the Expiration Time a Flip-in Date shall occur, except as provided in this Section 3.1, each Right shall constitute the right to purchase from the Company, upon exercise thereof in accordance with the terms hereof (but subject to Section 5.10), that number of shares of Common Stock having an aggregate Market Price on the Stock Acquisition Date that gave rise to the Flip-in Date equal to twice the Exercise Price for an amount in cash equal to the Exercise Price (such right to be appropriately adjusted in order to protect the interests of the holders of Rights generally in the event that on or after such Stock Acquisition Date any of the events described in Section 2.3(a) or (b), or any analogous event, shall have occurred with respect to the Common Stock).

(b) Notwithstanding the foregoing, any Rights that are or were Beneficially Owned on or after the Stock Acquisition Date by an Acquiring Person or an Affiliate or Associate thereof or by any transferee, direct or indirect, of any of the foregoing shall become null and void and any holder of such Rights (including transferees) shall thereafter have no right to exercise or transfer such Rights under any provision of this Agreement. If any Rights Certificate is presented for assignment or exercise and the Person presenting the same will not complete the certification set forth at the end of the form of assignment or notice of election to exercise and provide such additional evidence of the identity of the Beneficial Owner and its Affiliates and Associates (or former Beneficial Owners and their Affiliates and Associates) as the Company or the Rights Agent shall reasonably request, then the Company shall be entitled conclusively to deem the Beneficial Owner thereof to be an Acquiring Person or an Affiliate or Associate thereof or a transferee of any of the foregoing and accordingly will deem the Rights

-22-

evidenced thereby to be null and void and not transferable or exercisable. The Company shall give the Rights Agent written notice of the identity of any such Acquiring Person, Associate or Affiliate, or the nominee of any of the foregoing, and the Rights Agent may rely on such notice in carrying out its duties under this Agreement and shall be deemed not to have any knowledge of the identity of any such Acquiring Person, Associate or Affiliate, or the nominee of any of the foregoing unless and until it shall have received such notice.

(c) The Board of Directors of the Company may, at its option, at any time after a Flip-in Date and prior to the time that an Acquiring Person becomes the Beneficial Owner of more than 50% of the outstanding shares of Common Stock elect to exchange all (but not less than all) the then outstanding Rights (which shall not include Rights that have become null and void pursuant to the provisions of Section 3.1(b)) for shares of Common Stock at an exchange ratio of one share of Common Stock per Right, appropriately adjusted in order to protect the interests of holders of Rights generally in the event that after the Separation Time any of the events described in Section 2.3(a) or (b), or any analogous event, shall have occurred with respect to the Common Stock (such exchange ratio, as adjusted from time to time, being hereinafter referred to as the “Exchange Ratio”).

Immediately upon the action of the Board of Directors of the Company electing to exchange the Rights, without any further action and without any notice, the right to exercise the Rights will terminate and each Right (other than Rights that have become null and void pursuant to Section 3.1(b)), whether or not previously exercised, will thereafter represent only the right to receive a number of shares of Common Stock equal to the Exchange Ratio. Promptly after the action of the Board of Directors electing to exchange the Rights, the Company shall give written notice thereof (specifying the steps to be taken to receive shares of Common Stock in exchange

-23-

for Rights) to the Rights Agent and the holders of the Rights (other than Rights that have become null and void pursuant to Section 3.1(b)) outstanding immediately prior thereto by mailing such notice in accordance with Section 5.9.

Each Person in whose name any certificate for shares is issued (or for whom any registration on the stock transfer books of the Company is made) upon the exchange of Rights pursuant to this Section 3.1(c) or Section 3.1(d) shall for all purposes be deemed to have become the holder of record of the shares represented thereby on, and such certificate (or registration on the stock transfer books of the Company) shall be dated (or registered as of), the date upon which the Rights Certificate evidencing such Rights was duly surrendered and payment of any applicable taxes and other governmental charges payable by the holder was made; provided, however, that if the date of such surrender and payment is a date upon which the stock transfer books of the Company are closed, such Person shall be deemed to have become the record holder of such shares on, and such certificate (or registration on the stock transfer books of the Company) shall be dated (or registered as of), the next succeeding Business Day on which the stock transfer books of the Company are open.

(d) Whenever the Company shall become obligated under Section 3.1(a) or (c) to issue shares of Common Stock upon exercise of or in exchange for Rights, the Company, at its option, may substitute therefor shares of Preferred Stock, at an initial rate of one one-hundredth of a share of Preferred Stock for each share of Common Stock so issuable, as appropriately adjusted to reflect adjustments in the voting rights of the Preferred Stock pursuant to the terms thereof, so that the fraction of a share of Preferred Stock delivered in lieu of each share of Common Stock shall have the same voting rights as one share of Common Stock.

-24-

(e) In the event that there shall not be sufficient treasury shares or authorized but unissued shares of Common Stock or Preferred Stock of the Company to permit the exercise or exchange in full of the Rights in accordance with Section 3.1(a) or if the Company so elects to make the exchange referred to in Section 3.1(c), the Company shall either (i) call a meeting of stockholders seeking approval to cause sufficient additional shares to be authorized (provided that if such approval is not obtained the Company will take the action specified in clause (ii) of this sentence) or (ii) take such action as shall be necessary to ensure and provide, to the extent permitted by applicable law and any agreements or instruments in effect on the Stock Acquisition Date to which it is a party, that each Right shall thereafter constitute the right to receive, (x) at the Company’s option, either (A) in return for the Exercise Price, debt or equity securities or other assets (or a combination thereof) having a fair value equal to twice the Exercise Price, or (B) without payment of consideration (except as otherwise required by applicable law), debt or equity securities or other assets (or a combination thereof) having a fair value equal to the Exercise Price, or (y) if the Board of Directors of the Company elects to exchange the Rights in accordance with Section 3.1(c), debt or equity securities or other assets (or a combination thereof) having a fair value equal to the product of the Market Price of a share of Common Stock on the Flip-in Date times the Exchange Ratio in effect on the Flip-in Date, where in any case set forth in (x) or (y) above the fair value of such debt or equity securities or other assets shall be as determined in good faith by the Board of Directors of the Company, after consultation with a nationally recognized investment banking firm.

3.2 Flip-over. (a) Prior to the Expiration Time, the Company shall not enter into any agreement with respect to, consummate or permit to occur any Flip-over Transaction or Event unless and until it shall have entered into a supplemental agreement with the Flip-over

-25-

Entity, for the benefit of the holders of the Rights, providing that, upon consummation or occurrence of the Flip-over Transaction or Event (i) each Right shall thereafter constitute the right to purchase from the Flip-over Entity, upon exercise thereof in accordance with the terms hereof, that number of shares of Flip-over Stock of the Flip-over Entity having an aggregate Market Price on the date of consummation or occurrence of such Flip-over Transaction or Event equal to twice the Exercise Price for an amount in cash equal to the Exercise Price (such right to be appropriately adjusted in order to protect the interests of the holders of Rights generally in the event that after such date of consummation or occurrence any of the events described in Section 2.3(a) or (b), or any analogous event, shall have occurred with respect to the Flip-over Stock) and (ii) the Flip-over Entity shall thereafter be liable for, and shall assume, by virtue of such Flip-over Transaction or Event and such supplemental agreement, all the obligations and duties of the Company pursuant to this Agreement. The provisions of this Section 3.2 shall apply to successive Flip-over Transactions or Events.

(b) Prior to the Expiration Time, the Company shall not enter into any agreement with respect to, consummate or permit to occur any Flip-over Transaction or Event if at the time thereof there are any rights, warrants or securities outstanding or any other arrangements, agreements or instruments that would eliminate or otherwise diminish in any material respect the benefits intended to be afforded by this Rights Agreement to the holders of Rights upon consummation of such transaction.

ARTICLE IV

THE RIGHTS AGENT

4.1 General. (a) The Company hereby appoints the Rights Agent to act as agent for the Company in accordance with the terms and conditions hereof, and the Rights Agent

-26-

hereby accepts such appointment. 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 other disbursements incurred in the preparation, delivery, amendment, administration and execution 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 (including, without limitation, the reasonable fees and expenses of counsel) incurred without gross negligence, bad faith or willful misconduct on the part of the Rights Agent (which gross negligence, bad faith or willful misconduct must be determined by a final, non-appealable order, judgment, decree or ruling of a court of competent jurisdiction), for any action taken, suffered or omitted to be done by the Rights Agent in connection with the acceptance, administration, exercise and performance of its duties under this Agreement, including, without limitation, the costs and expenses of defending against and appealing any claim of liability arising therefrom, directly or indirectly. The indemnity provided herein shall survive termination of this Agreement and the termination, exercise or expiration of the Rights and the resignation, replacement or removal of the Rights Agent. The costs and expenses incurred in enforcing this right of indemnification shall be paid by the Company. Anything to the contrary contained herein notwithstanding, in no event shall the Rights Agent be liable for special, punitive, indirect, incidental or consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Rights Agent has been advised of the likelihood of such loss or damage. Any liability of the Rights Agent under this Rights Agreement will be limited to the amount of fees paid by the Company to the Rights Agent.

-27-

(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 the acceptance and administration of this Agreement and the exercise and performance of its duties hereunder in reliance upon any certificate for securities (or registration on the stock transfer books of the Company) purchasable upon exercise of Rights, Rights Certificate, certificate 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 or opinion of counsel as set forth in Section 4.3. The Rights Agent shall not be deemed to have knowledge of any event of which it was supposed to receive notice thereof hereunder, and the Rights Agent shall be fully protected and shall incur no liability for failing to take action in connection therewith unless and until it has received such notice in writing.

4.2 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 is a party, or any Person succeeding to the shareholder services business of the Rights Agent or any successor Rights Agent, will 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 that such Person would be eligible for appointment as a successor Rights Agent under the provisions of Section 4.4 hereof. In case at the time such successor Rights Agent succeeds to the agency created by this Agreement any of the Rights Certificates have been countersigned but not delivered, any such

-28-

successor Rights Agent may adopt the countersignature of the predecessor Rights Agent and deliver such Rights Certificates so countersigned; and in case at that time any of the Rights Certificates have not been countersigned, any successor Rights Agent may countersign such Rights Certificates either in the name of the predecessor Rights Agent or in the name of the successor Rights Agent; and in all such cases such Rights Certificates will 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 is 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.

4.3 Duties of Rights Agent. The Rights Agent undertakes to perform only the duties and obligations expressly imposed by this Agreement (and no implied duties) 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) The Rights Agent may consult with legal counsel (who may be legal counsel for the Company or an employee of the Rights Agent), and the advice or opinion of such counsel will be full and complete 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 by it in accordance with such advice or opinion.

-29-

(b) Whenever in the performance of its duties under this Agreement the Rights Agent deems it necessary or desirable that any fact or matter (including, without limitation, the identity of any Acquiring Person and the determination of 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 a Person believed by the Rights Agent to be the Chairman of the Board, the President or any Vice President and by the Treasurer or any Assistant Treasurer or the Secretary or any Assistant Secretary of the Company and delivered to the Rights Agent; and such certificate will be full and complete 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 by it under the provisions of this Agreement in reliance upon such certificate.

(c) The Rights Agent will be liable hereunder only for its own gross negligence, bad faith or willful misconduct (as determined by a final, non-appealable order, judgment, decree or ruling of a court of competent jurisdiction).

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

(e) The Rights Agent shall not have any liability or 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

-30-

of any certificate, if any, for securities purchasable upon exercise of Rights or Rights Certificate (except its countersignature thereof); nor will it be responsible for any breach by the Company of any covenant or condition contained in this Agreement or in any Rights Certificate; nor will it be responsible for any change in the exercisability of the Rights (including the Rights becoming null and void pursuant to this Agreement) or any change or adjustment in the terms of the Rights including the manner, method or amount thereof provided for in Sections 2.3, 3.1 or 3.2 hereof or the ascertaining of the existence of facts that would require any such change or adjustment (except with respect to the exercise of Rights after receipt of the certificate contemplated by Section 2.3 describing any such change or adjustment upon which the Rights Agent may rely); nor will it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any securities purchasable upon exercise of Rights or any Rights or as to whether any securities purchasable upon exercise of Rights will, when issued, be duly and validly authorized, executed, issued and delivered and 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 any Person believed by the Rights Agent to be the Chairman of the Board, the President or any Vice President or the Secretary or any Assistant Secretary or the Treasurer or any Assistant Treasurer of the Company, and to apply to such Persons for advice or instructions in connection with its duties, and such instructions shall be full authorization and protection to the Rights Agent and the Rights Agent shall incur no

-31-

liability for or in respect of any action taken, suffered or omitted by it in accordance with instructions of any such Person or for any delay in acting while waiting for those instructions. The Rights Agent shall be fully authorized and protected in relying upon the most recent instructions received by any such officer.

(h) The Rights Agent and any member, affiliate, stockholder, director, officer or employee of the Rights Agent may buy, sell or deal in Common Stock, 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 or any such member, affiliate, stockholder, director, officer or employee 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 (through its directors, officers and employees) or by or through its attorneys or agents, and the Rights Agent will 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 or any other Person resulting from any such act, default, neglect or misconduct, absent gross negligence, bad faith or willful misconduct in the continued employment thereof (each as determined by a final, non-appealable order, judgment, decree or ruling of a court of competent jurisdiction).

(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 it believes that repayment of such funds or adequate indemnification against such risk or liability is not reasonably assured to it.

-32-

4.4 Change of Rights Agent. The Rights Agent may resign and be discharged from its duties under this Agreement upon 30 days’ notice (or such lesser notice as is acceptable to the Company) in writing mailed to the Company and to each transfer agent of Common Stock known to the Rights Agent by registered or certified mail, and to the holders of the Rights in accordance with Section 5.9. The Company may remove the Rights Agent upon 30 days’ notice in writing, mailed to the Rights Agent and to each transfer agent of the Common Stock known to the Rights Agent by registered or certified mail, and to the holders of the Rights in accordance with Section 5.9. If the Rights Agent should resign or be removed or otherwise become incapable of acting, the Company will appoint a successor to the Rights Agent. If the Company fails to make such appointment within a period of 30 days after such removal or after it has been notified in writing of such resignation or incapacity by the resigning or incapacitated Rights Agent or by the holder of any Rights (which holder shall, with such notice, submit such holder’s Rights Certificate for inspection by the Company), then the holder of any Rights or the Rights Agent 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 Person (or an affiliate of such a Person) organized and doing business under the laws of the United States or any state of the United States, in good standing, which is authorized under such laws to exercise the powers of the Rights Agent contemplated by this Agreement 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. After appointment, the successor Rights Agent will 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

-33-

property at the time held by it hereunder, and execute and deliver any further assurance, conveyance, act or deed necessary for the purpose. Not later than the effective date of any such appointment, the Company will file notice thereof in writing with the predecessor Rights Agent and each transfer agent of the Common Stock, and mail a notice thereof in writing to the holders of the Rights. Failure to give any notice provided for in this Section 4.4, however, 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.

ARTICLE V

MISCELLANEOUS

5.1 Redemption. (a) The Board of Directors of the Company may, at its option, at any time prior to the Flip-in Date, elect to redeem all (but not less than all) the then outstanding Rights at the Redemption Price and the Company, at its option, may pay the Redemption Price either in cash or shares of Common Stock or other securities of the Company deemed by the Board of Directors, in the exercise of its sole discretion, to be at least equivalent in value to the Redemption Price.

(b) Immediately upon the action of the Board of Directors of the Company electing to redeem the Rights (or, if the resolution of the Board of Directors electing to redeem the Rights states that the redemption will not be effective until the occurrence of a specified future time or event, upon the occurrence of such future time or event), without any further action and without any notice, the right to exercise the Rights will terminate and each Right, whether or not previously exercised, will thereafter represent only the right to receive the Redemption Price in cash or securities, as determined by the Board of Directors. Promptly after the Rights are redeemed, the Company shall give notice of such redemption to the Rights Agent and the holders of the then outstanding Rights by mailing such notice in accordance with Section 5.9.

-34-

5.2 Expiration. The Rights and this Agreement shall expire at the Expiration Time and no Person shall have any rights pursuant to this Agreement or any Right after the Expiration Time, except, if the Rights are exchanged or redeemed, as provided in Sections 3.1 or 5.1 hereof, respectively.

5.3 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 number or kind or class of shares of stock purchasable upon exercise of Rights made in accordance with the provisions of this Agreement. In addition, in connection with the issuance or sale of shares of Common Stock by the Company following the Separation Time and prior to the Expiration Time pursuant to the terms of securities convertible or redeemable into shares of Common Stock or to options, in each case issued or granted prior to, and outstanding at, the Separation Time, the Company shall issue to the holders of such shares of Common Stock, Rights Certificates representing the appropriate number of Rights in connection with the issuance or sale of such shares of Common Stock; provided, however, in each case, (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 to the Person to whom such Rights Certificates would be issued, (ii) no such Rights Certificates shall be issued if, and to the extent that, appropriate adjustment shall have otherwise been made in lieu of the issuance thereof, and (iii) the Company shall have no obligation to distribute Rights Certificates to any Acquiring Person or Affiliate or Associate of an Acquiring Person or any transferee of any of the foregoing.

-35-

5.4 Supplements and Amendments. Subject to the last sentence of this Section 5.4, the Company may, and the Rights Agent, if so directed by the Company, shall from time to time supplement or amend this Agreement without the approval of any holders of Rights (i) prior to the Flip-in Date, in any respect and (ii) on or after the Flip-in Date, to make any changes that the Company may deem necessary or desirable and which shall not materially adversely affect the interests of the holders of Rights generally or in order to cure any ambiguity or to correct or supplement any provision contained herein which may be inconsistent with any other provisions herein or otherwise defective. The Rights Agent will, upon the delivery of a certificate from an appropriate officer of the Company that states that the proposed supplement or amendment complies with this Section 5.4, duly execute and deliver any supplement or amendment hereto requested by the Company which satisfies the terms of the preceding sentence. Notwithstanding anything contained in this Agreement to the contrary, the Rights Agent may, but shall not be obligated to, enter into any supplement or amendment that affects the Rights Agent’s own rights, duties or immunities under this Agreement and it shall not be bound by any such supplement or amendment not executed by it.

5.5 Fractional Shares. If the Company elects not to issue certificates representing (or register on the stock transfer books of the Company) fractional shares upon exercise or redemption of Rights, the Company shall, in lieu thereof, in the sole discretion of the Board of Directors, either (a) evidence such fractional shares by depositary receipts issued pursuant to an appropriate agreement between the Company and a depositary selected by it, providing that each holder of a depositary receipt shall have all of the rights, privileges and

-36-

preferences to which such holder would be entitled as a beneficial owner of such fractional share, or (b) pay to the registered holder of such Rights the appropriate fraction of the Market Price per share in cash. 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. The Rights Agent shall be fully protected in relying upon such a certificate and shall have no duty with respect to, and shall not be deemed to have knowledge of any payment for fractional Rights or fractional shares under any Section of this Agreement relating to the payment of fractional Rights or fractional shares unless and until the Rights Agent shall have received such a certificate and sufficient monies.

5.6 Rights of Action. Subject to the terms of this Agreement (including Sections 3.1(b) and 5.14), rights of action in respect of this Agreement, other than rights of action vested solely in the Rights Agent, are vested in the respective holders of the Rights; and any holder of any Rights, without the consent of the Rights Agent or of the holder of any other Rights, may, on such holder’s own behalf and for such holder’s own benefit and the benefit of other holders of Rights, 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 such holder’s Rights in the manner provided in such holder’s 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 by the Company of this Agreement and will be entitled to specific performance of the obligations under, and injunctive relief against actual or threatened violations by the Company of, the obligations of any Person subject to this Agreement.

-37-

5.7 Holder of Rights Not Deemed a Stockholder. No holder, as such, of any Rights shall be entitled to vote, receive dividends or be deemed for any purpose the holder of shares or any other securities which may at any time be issuable on the exercise of such Rights, nor shall anything contained herein or in any Rights Certificate be construed to confer upon the holder of any Rights, as such, any of the rights of a stockholder of the Company or any right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, or to give or withhold consent to any corporate action, or to receive notice of meetings or other actions affecting stockholders (except as provided in Section 5.8 hereof), or to receive dividends or subscription rights, or otherwise, until such Rights shall have been exercised or exchanged in accordance with the provisions hereof.

5.8 Notice of Proposed Actions. In case the Company shall propose on or after the Separation Time and prior to the Expiration Time (i) to effect or permit a Flip-over Transaction or Event or (ii) to effect the liquidation, dissolution or winding up of the Company, then, in each such case, the Company shall give to each holder of a Right, in accordance with Section 5.9 hereof, a notice of such proposed action, which shall specify the date on which such Flip-over Transaction or Event, liquidation, dissolution, or winding up is to take place, and such notice shall be so given at least 20 Business Days prior to the date of the taking of such proposed action.

5.9 Notices. Notices or demands authorized or required by this Agreement to be given or made by the Rights Agent or by the holder of any Rights to or on the Company shall

No holder of this Rights Certificate, as such, shall be entitled to vote or receive dividends or be deemed for any purpose the holder of Common Stock or of any other securities 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 stockholder of the Company or any right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, or to give or withhold consent to any corporate action, or to receive notice of meetings or other actions affecting stockholders (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 or exchanged as provided in the Rights Agreement.

FORM OF ARTICLE IV. C TO RESTATED CERTIFICATE OF INCORPORATION

OF ACUITY BRANDS HOLDINGS, INC. (SETTING FORTH TERMS OF

PARTICIPATING PREFERRED STOCK OF ACUITY BRANDS HOLDINGS, INC.)

PARTICIPATING PREFERRED STOCK

There is hereby established a series of Preferred Stock, $.01 par value, of the Corporation, and the designation and certain terms, powers, preferences and other rights of the shares of such series, and certain qualifications, limitations and restrictions thereon, are hereby fixed as follows:

(i) The distinctive serial designation of this series shall be “Participating Preferred Stock” (hereinafter called “this Series”). Each share of this Series shall be identical in all respects with the other shares of this Series except as to the dates from and after which dividends thereon shall be cumulative.

(ii) The number of shares in this Series shall initially be 5,000,000, which number may from time to time be increased or decreased (but not below the number then outstanding) by the Board of Directors. Shares of this Series purchased by the Corporation shall be canceled and shall revert to authorized but unissued shares of Preferred Stock undesignated as to series. Shares of this Series may be issued in fractional shares, which fractional shares shall entitle the holder, in proportion to such holder’s fractional share, to all rights of a holder of a whole share of this Series.

(iii) The holders of full or fractional shares of this Series shall be entitled to receive, when and as declared by the Board of Directors, but only out of funds legally available therefor, dividends, (A) on each date that dividends or other distributions (other than dividends or distributions payable in Common Stock of the Corporation) are payable on or in respect of Common Stock comprising part of the Reference Package (as defined below), in an amount per whole share of this Series equal to the aggregate amount of dividends or other distributions (other than dividends or distributions payable in Common Stock of the Corporation) that would be payable on such date to a holder of the Reference Package and (B) on the last day of March, June, September and December in each year, in an amount per whole share of this Series equal to the excess (if any) of $25.00 over the aggregate dividends paid per whole share of this Series during the three month period ending on such last day. Each such dividend shall be paid to the holders of record of shares of this Series on the date, not exceeding sixty days preceding such dividend or distribution payment date, fixed for the purpose by the Board of Directors in advance of payment of each particular dividend or distribution. Dividends on each full and each fractional share of this Series shall be cumulative from the date such full or fractional share is originally issued; provided that any such full or fractional share originally issued after a dividend record date and on or prior to the dividend payment date to which such record date relates shall not be entitled to receive the dividend payable on such dividend payment date or any amount in respect of the period from such original issuance to such dividend payment date.

The term “Reference Package” shall initially mean 100 shares of Common Stock, par value $.01 per share (“Common Stock”), of the Corporation. In the event the Corporation shall at any time after the Close of Business on September 27, 2007 (A) declare or pay a dividend on any Common Stock payable in Common Stock, (B) subdivide any Common Stock or (C) combine any Common Stock into a smaller number of shares, then and in each such case the Reference Package after such event shall be the Common Stock that a holder of the Reference Package immediately prior to such event would hold thereafter as a result thereof.

Holders of shares of this Series shall not be entitled to any dividends, whether payable in cash, property or stock, in excess of full cumulative dividends, as herein provided on this Series.

So long as any shares of this Series are outstanding, no dividend (other than a dividend in Common Stock or in any other stock ranking junior to this Series as to dividends and upon liquidation) shall be declared or paid or set aside for payment or other distribution declared or made upon the Common Stock or upon any other stock ranking junior to this Series as to dividends or upon liquidation, unless the full cumulative dividends (including the dividend to be paid upon payment of such dividend or other distribution) on all outstanding shares of this Series shall have been, or shall contemporaneously be, paid. When dividends are not paid in full upon this Series and other stock ranking on a parity as to dividends with this Series, all dividends declared upon shares of this Series and any other stock ranking on a parity as to dividends shall be declared pro rata so that in all cases the amount of dividends declared per share on this Series and such other stock shall bear to each other the same ratio that accumulated dividends per share on the shares of the Series and such other stock bear to each other. Neither the Common Stock nor any other stock of the Corporation ranking junior to or on a parity with this Series as to dividends or upon liquidation shall be redeemed, purchased or otherwise acquired for any consideration (or any moneys be paid to or made available for a sinking fund for the redemption of any shares of any such stock) by the Corporation (except by conversion into or exchange for stock of the Corporation ranking junior to this Series as to dividends and upon liquidation), unless the full cumulative dividends (including the dividend to be paid upon payment of such dividend, distribution, redemption, purchase or other acquisition) on all outstanding shares of this Series shall have been, or shall contemporaneously be, paid.

(iv) In the event of any merger, consolidation, reclassification or other transaction in which the shares of Common Stock are exchanged for or changed into other stock or securities, cash and/or any other property, then in any such case the shares of this Series shall at the same time be similarly exchanged or changed in an amount per whole share equal to the aggregate amount of stock, securities, cash and/or any other property (payable in kind), as the case may be, that a holder of the Reference Package would be entitled to receive as a result of such transaction.

(v) In the event of any liquidation, dissolution or winding up of the affairs of the Corporation, whether voluntary or involuntary, the holders of full and fractional shares of this Series shall be entitled, before any distribution or payment is made on any date to the holders of the Common Stock or any other stock of the Corporation ranking junior to this Series upon liquidation, to be paid in full an amount per whole share of this Series equal to the greater of

-2-

(A) $10,000.00 or (B) the aggregate amount distributed or to be distributed prior to such date in connection with such liquidation, dissolution or winding up to a holder of the Reference Package (such greater amount being hereinafter referred to as the “Liquidation Preference”), together with accrued dividends to such distribution or payment date, whether or not earned or declared. If such payment shall have been made in full to all holders of shares of this Series, the holders of shares of this Series as such shall have no right or claim to any of the remaining assets of the Corporation.

In the event the assets of the Corporation available for distribution to the holders of shares of this Series upon any liquidation, dissolution or winding up of the Corporation, whether voluntary or involuntary, shall be insufficient to pay in full all amounts to which such holders are entitled pursuant to the first paragraph of this Section (v), no such distribution shall be made on account of any shares of any other class or series of Preferred Stock ranking on a parity with the shares of this Series upon such liquidation, dissolution or winding up unless proportionate distributive amounts shall be paid on account of the shares of this Series, ratably in proportion to the full distributable amounts for which holders of all such parity shares are respectively entitled upon such liquidation, dissolution or winding up.

Upon the liquidation, dissolution or winding up of the Corporation, the holders of shares of this Series then outstanding shall be entitled to be paid out of assets of the Corporation available for distribution to its stockholders all amounts to which such holders are entitled pursuant to the first paragraph of this Section (v) before any payment shall be made to the holders of Common Stock or any other stock of the Corporation ranking junior upon liquidation to this Series.

For the purposes of this Section (v), the consolidation or merger of, or binding share exchange by, the Corporation with any other corporation shall not be deemed to constitute a liquidation, dissolution or winding up of the Corporation.

(vi) The shares of this Series shall not be redeemable.

(vii) In addition to any other vote or consent of stockholders required by law or by the Certificate of Incorporation, as amended, of the Corporation, each whole share of this Series shall, on any matter, vote as a class with any other capital stock comprising part of the Reference Package and voting on such matter and shall have the number of votes thereon that a holder of the Reference Package would have.
