This is one of the Securities of a series designated under the Indenture described herein.

[Reverse of Security]

     This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Indenture, dated as of September 10, 2007 (herein called the “Indenture”), between the Company and The Bank of New York, as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof.

     The Securities of this series are subject to redemption upon not less than 30 nor more than 60 days’ notice by mail, at any time, as a whole or in part, at the election of the Company, at a redemption price equal to the greater of:

	(i)		100% of the principal amount of the Securities to be redeemed; and
	(ii)		the sum of the present values of the remaining scheduled payments of principal and interest thereon (not including any portion of such payments of interest accrued as of the date of redemption), discounted to the date of redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below), plus 20 basis points,

     plus, in each case, accrued and unpaid interest thereon to the date of redemption. Notwithstanding the foregoing, installments of interest on the Securities that are due and payable on interest payment dates falling on or prior to a redemption date will be payable on the interest payment date to the registered holders as of the close of business on the relevant record date for such interest payment date. “Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having a maturity comparable to the remaining term of the Securities to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Securities. “Comparable Treasury Price” means, with respect to any redemption date, (i) the average of four Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, (ii) if the Trustee can only obtain less than four such Reference Treasury Dealer Quotations, the average of all such quotations, or (iii) if the Trustee can only obtain one Reference Treasury Dealer Quotation, such quotation. “Quotation Agent” means the Reference Treasury Dealer appointed by us. “Reference Treasury Dealer” means (i) each of Citigroup Global Markets Inc. and J.P. Morgan Securities Inc. (or their respective affiliates that are Primary Treasury Dealers) and their respective successors; provided, however, that if any of the foregoing shall cease to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), we will substitute therefor another Primary Treasury Dealer, and (ii) any other Primary Treasury Dealer

selected by us. “Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third business day preceding such redemption date. “Treasury Rate” means, with respect to any redemption date, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date.

     If less than all of the Securities are to be redeemed, the Securities to be redeemed shall be selected by lot by The Depository Trust Company. In the event of redemption of this Security in part only, a new Security or Securities of this series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.

     If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

     If a Change of Control Repurchase Event (as defined below) occurs, unless we have exercised our right to redeem the Securities as described above, we will make an offer to each holder of Securities to repurchase all or any part (in integral multiples of $1,000) of that holder’s Securities at a repurchase price in cash equal to 101% of the aggregate principal amount of Securities repurchased plus any accrued and unpaid interest on the Securities repurchased to the date of purchase. Within 30 days following any Change of Control Repurchase Event or, at our option, prior to any Change of Control (as defined below), but after the public announcement of an impending Change of Control, we will mail a notice to each holder, with a copy to the Trustee, describing the transaction or transactions that constitute or may constitute the Change of Control Repurchase Event and offering to repurchase Securities on the payment date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed. The notice shall, if mailed prior to the date of consummation of the Change of Control, state that the offer to purchase is conditioned on the Change of Control Repurchase Event occurring on or prior to the payment date specified in the notice.

     On the Change of Control Repurchase Event payment date, we will, to the extent lawful: (1) accept for payment all Securities or portions of Securities (in integral multiples of $1,000) properly tendered pursuant to our offer; (2) deposit with the paying agent an amount equal to the aggregate purchase price in respect of all Securities or portions of Securities properly tendered; and (3) deliver or cause to be delivered to the Trustee the Securities properly accepted, together with an officers’ certificate stating the aggregate principal amount of Securities being purchased by us. The paying agent will promptly mail to each holder of Securities properly tendered the purchase price for the Securities, and the Trustee will promptly authenticate and mail (or cause to be transferred

by book-entry) to each holder a new note equal in principal amount to any unpurchased portion of any Securities surrendered; provided, that each new note will be in a principal amount of $2,000 or an integral multiple of $1,000 above that amount. We will not be required to make an offer to repurchase the Securities upon a Change of Control Repurchase Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by us and such third party purchases all Securities properly tendered and not withdrawn under its offer.

     “Below Investment Grade Rating Event” means the Securities are rated below Investment Grade by each of the Rating Agencies on any date from the date of the public notice of an arrangement that could result in a Change of Control until the end of the 60-day period following public notice of the occurrence of a Change of Control (which period shall be extended so long as the rating of the Securities is under publicly announced consideration for possible downgrade by any of the Rating Agencies); provided that a Below Investment Grade Rating Event otherwise arising by virtue of a particular reduction in rating shall not be deemed to have occurred in respect of a particular Change of Control (and thus shall not be deemed a Below Investment Grade Rating Event for purposes of the definition of Change of Control Repurchase Event hereunder) if the Rating Agencies making the reduction in rating to which this definition would otherwise apply do not announce or publicly confirm or inform the Trustee in writing at its request that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the applicable Change of Control (whether or not the applicable Change of Control shall have occurred at the time of the Below Investment Grade Rating Event). “Change of Control” means the occurrence of any of the following: (1) the direct or indirect sale, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of our properties or assets and those of our subsidiaries taken as a whole to any “person” or “group” (as that term is used in Section 13(d)(3) of the Exchange Act), other than us or one of our subsidiaries; (2) the adoption of a plan relating to our liquidation or dissolution; (3) the first day on which a majority of the members of our Board of Directors are not Continuing Directors; (4) the consummation of any transaction or series of related transactions (including, without limitation, any merger or consolidation) the result of which is that any “person” or “group” (as that term is used in Section 13(d)(3) of the Exchange Act), other than us, one or more of our wholly-owned subsidiaries, or one or more Haas Family Members, becomes the beneficial owner, directly or indirectly, of more than 50% of the then outstanding number of shares of our Voting Stock; or (5) the consummation of a so-called “going private/Rule 13e-3 Transaction” that results in any of the effects described in paragraph (a)(3)(ii) of Rule 13e-3 under the Exchange Act (or any successor provision), following which Haas Family Members beneficially own, directly or indirectly, more than 50% of our Voting Stock, measured by voting power rather than number of shares. “Change of Control Repurchase Event” means the occurrence of both a Change of Control and a Below Investment Grade Rating Event. “Continuing Directors” means, as of any date of determination, any member of our Board of Directors who (1) was a member of such Board of Directors on the date of the issuance of the Securities; or (2) was nominated for election or elected to such Board of Directors with

the approval of a majority of the Continuing Directors who were members of such Board of Directors at the time of such nomination or election (either by a specific vote or by approval of our proxy statement in which such member was named as a nominee for election as a director). “Haas Family Members” includes only the following persons:  (i) each descendant of Otto Haas (a “Haas Descendant”) and their respective estates, guardians, conservators or committees; (ii) each “Family Controlled Trust” (as defined below); and (iii) the trustees, in their respective capacities as such, of each Family Controlled Trust.  The term “Family Controlled Trust” means any trust the primary beneficiaries of which are Haas Descendants, spouses of Haas Descendants and/or charitable organizations, provided that if the trust is a wholly charitable trust, at least a majority of the trustees of such trust consist of Haas Descendants or their spouses. “Investment Grade” means a rating of Baa3 or better by Moody’s (or its equivalent under any successor rating categories of Moody’s) and a rating of BBB- or better by S&P (or its equivalent under any successor rating categories of S&P) or the equivalent investment grade credit rating from any additional Rating Agency or Rating Agencies selected by us. “Moody’s” means Moody’s Investors Service Inc. “Rating Agency” means (1) each of Moody’s and S&P; and (2) if any of Moody’s or S&P ceases to rate the Securities or fails to make a rating of the Securities publicly available for reasons outside of our control, a “nationally recognized statistical rating organization” within the meaning of Rule 15c3-1(c)(2)(vi)(F) under the Exchange Act, selected by us as a replacement agency for Moody’s or S&P, as the case may be. “S&P” means Standard & Poor’s Ratings Services, a division of McGraw-Hill, Inc. “Voting Stock” means, with respect to any person, capital stock of any class or kind the holders of which are ordinarily, in the absence of contingencies, entitled to vote for the election of directors (or persons performing similar functions) of such Person, even if the right so to vote has been suspended by the happening of such a contingency.

     The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

     No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of (and premium, if any) and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.

     As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

     The Securities of this series are issuable only in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 above that amount. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

     No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

     Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

     All terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture.
