Notwithstanding anything to the contrary herein, the aggregate amount of Securities which the TCW/Crescent Purchasers are collectively purchasing hereunder shall be allocated among the TCW/Crescent Purchasers in accordance with the allocation percentage opposite each TCW/Crescent Purchaser's name under the heading "TCW/Crescent Purchaser Allocations" on the "Schedule of TCW/Crescent Allocations" attached hereto. (c) The initial closing of the purchase and sale of the Common Units and Class B Preferred Units (the "INITIAL CLOSING") shall take place at the offices of Kirkland & Ellis LLP, 200 E. Randolph Drive, Chicago, Illinois at 10:00 a.m. on the date hereof. (d) The Company has been organized for the purpose of owning a company or companies in the consumer products industry. In addition to the $102,220,951 invested by the GTCR Purchasers on the Initial Closing Date pursuant to SECTION 1.B(a) above, the GTCR Purchasers intend to provide up to $144,779,049 in equity financing to the Company as the equity portion of the debt and equity financing necessary to fund such business(es), in each case as approved by the Board of Managers of the Company (the "BOARD") and the GTCR Purchasers (an "APPROVED USE"). The GTCR Purchasers' obligation to purchase any Securities pursuant to this SECTION 1.B will be conditioned on the Company's not being in default under any of its material agreements, adequate debt financing being available to fund any proposed acquisition or other Approved Use on terms satisfactory to the GTCR Purchasers, and the Company's operations and the acquisition or other Approved Use being satisfactory to the GTCR Purchasers. In order to implement the foregoing, the GTCR Purchasers may purchase from time to time after the Initial Closing, upon the written request of the Board in connection with an Approved Use, up to an aggregate of 144,779.049 Class B Preferred Units at a price of $1,000 per unit (as adjusted from time to time as a result of unit dividends, unit splits, recapitalizations and similar events) (each such purchase, a "SUBSEQUENT CLOSING"). For any Subsequent Closing, each GTCR Purchaser shall purchase the percentage of such Securities set forth next to such GTCR Purchaser's name on the signature page attached hereto by payment of the aggregate purchase price thereof by wire transfer of immediately available funds to such account as is designated by the Company.

At the time of any Subsequent Closing, the GTCR Purchasers shall be entitled to receive, and the Company shall be obligated to deliver, satisfactory representations and warranties and all other information and documentation as the GTCR Purchasers may reasonably request. (e) TCW/CRESCENT SUBSEQUENT CLOSINGS. (i) In connection with each Subsequent Closing, the TCW/Crescent Purchasers may, but shall not be obligated to, purchase a number of Class B Preferred Units equal to the total number of Class B Preferred Units being purchased at such Subsequent Closing multiplied by .02851 and on the same terms and conditions as the GTCR Purchasers; provided that if the TCW/Crescent Purchasers choose not to purchase all of the Class B Preferred Units 2 <Page> they are entitled to purchase at any Subsequent Closing, they may not purchase Class B Preferred Units at such Subsequent Closing or at any Subsequent Closing thereafter. (ii) In connection with any Subsequent Closing in which the TCW/Crescent Purchasers do not purchase shares of Class B Preferred Units, the GTCR Purchasers shall have the right to purchase from the TCW/Crescent Purchasers and transferees a number of Common Units. The number of Common Units to be purchased hereunder will be determined by calculating the amount that the TCW/Crescent Purchasers would have been entitled to invest had the TCW/Crescent Purchasers participated in such Subsequent Closing and dividing that amount by $7,127,858 (i.e., the TCW/Crescent Purchasers' total committed equity) (the "Ratio"). The Ratio will then be multiplied by the number of Common Units held by the TCW/Crescent Purchasers and its transferees immediately prior to such Subsequent Closing. Such product will then be adjusted to give effect to any change in the Fair Market Value of the Company and its Subsidiaries between the date hereof and the date immediately preceding such Subsequent Closing before giving effect to such Subsequent Closing by dividing such product by the multiple of such increase in Fair Market Value of the Company and its Subsidiaries or by 1 minus the percentage decrease in such Fair Market Value of the Company and its Subsidiaries, as the case may be. Such right to purchase in favor of the GTCR Purchasers (i) must be exercised on the date of the Subsequent Closing if the TCW/Crescent Purchasers (or their transferees, as the case may be) have notified the GTCR Purchasers at least three (3) Business Days prior to such Subsequent Closing that they do not intend to participate in such Subsequent Closing or otherwise within five (5) Business Days after such Closing and (ii) shall not, under any circumstances, permit the GTCR Purchasers to purchase any Common Units held by TCW/Crescent Purchasers or their transferees as a result of the exercise of the TCW Warrants (as defined in that certain Warrant Agreement dated as of the date hereof by and among the Company, GTCR Capital Partners, L.P. and the TCW/Crescent Lenders (as defined therein)). "Fair Market Value" for purposes of this Section 1.B(e) shall be the fair market value of all equity of the Company using the methodology procedures set forth in the definition of Fair Market Value in Section 6 hereof. (iii) The purchase price for each Common Unit repurchased pursuant to this Section 1.B(e) will be $0.10 per unit (each as proportionately adjusted for all subsequent unit splits, unit dividends and other recapitalizations). (iv) The closing of the purchase of the Common Units pursuant to the this Section 1.B(e) shall take place on the date designated in a notice given to the TCW/Crescent Purchasers in accordance herewith, which date shall not be more than 30 days nor less than five days after the delivery of such notice. Each GTCR Purchaser will pay for the Common Units to be purchased by it by a check or wire transfer of immediately available funds. The GTCR Purchasers will be entitled to receive customary representations and warranties from the sellers regarding such sale and to require that all sellers' signatures be guaranteed. Section 2.
