Item 2. Identity and Background

Item 2(a) is hereby amended and supplemented by adding the following at the end thereof:

This Amendment No. 7 is filed by JLL Building Holdings, LLC, a Delaware limited liability company (“JLL Holdings”); JLL Partners Fund V, L.P., a Delaware limited partnership (“JLL Fund V”) and the sole member of JLL Holdings; JLL Associates V, L.P., a Delaware limited partnership (“JLL Associates V”) and the general partner of JLL Fund V; JLL Associates G.P. V, L.L.C., a Delaware limited liability company (“JLL Associates G.P. ”) and the general partner of JLL Associates V; and Mr. Paul S. Levy, the sole member of JLL Associates G.P. (JLL Holdings, JLL Fund V, JLL Associates V, JLL Associates G.P., and Mr. Levy collectively being the “JLL Reporting Persons”). Except as specifically amended by this Amendment No. 7, items in the Schedule 13D are unchanged.

The agreement among the JLL Reporting Persons to file this Schedule 13D jointly in accordance with rule 13d-1(k)(1) of the Securities Exchange Act of 1934, as amended, is attached hereto as Exhibit A.

Information in this Amendment No. 7 with respect to each of the JLL Reporting Persons is given solely by that particular JLL Reporting Person, and none of the Warburg Pincus Reporting Persons has any responsibility for the accuracy or completeness of information with respect to the JLL Reporting Persons. Capitalized terms used herein that are not defined herein have the meanings ascribed to them in the Schedule 13D.

Item 3. Source and Amount of Funds or Other Consideration

Item 3 is hereby amended and supplemented by adding the following at the end thereof:

JLL Fund V will obtain the funds used to acquire any securities purchased by it or by one of its affiliates pursuant to the Equity Commitment Letter (as defined below), as described in Item 4, from capital contributions of its partners.

Item 4. Purpose of Transaction

Item 4 is hereby amended and supplemented by adding the following at the end thereof:

On April 13, 2015, the Company entered into a securities purchase agreement pursuant to which it will acquire all of the issued and outstanding equity interests of ProBuild Holdings LLC (“ProBuild”). As a condition to a debt commitment that the Company has received in connection with its proposed acquisition of ProBuild, the Company is obligated to raise at least $100 million of net proceeds from the sale of its equity securities. The JLL Reporting Persons understand that the Company intends to raise such proceeds from a public offering of shares of the Company’s Common Stock. Pursuant to an equity commitment letter (the “Equity Commitment Letter”) among JLL Fund V, Warburg Pincus Fund IX, and the Company, dated April 13, 2015, that was required by the sellers of ProBuild, in the event that the Company is unable to raise such proceeds in a public offering of its equity securities, JLL Fund V has agreed to purchase $40 million of the Company’s Common Stock and Warburg Pincus Fund IX has agreed to purchase $60 million of the Company’s Common Stock, in each case, at a purchase price per share of the Company’s Common Stock equal to the lower of (i) the ten-day weighted average volume closing price of the Company’s Common Stock for the period ended March 26, 2015, and (ii) a discount of twenty percent (20%) from the ten-day weighted average volume closing price of the Company’s Common Stock for the period ending on the trading day immediately prior to the closing of the Company’s acquisition of ProBuild. Pursuant to the requirements of the Nasdaq Stock Market, the Company has committed to seek approval from its stockholders for the possible issuance of Common Stock to JLL Fund V and Warburg Pincus Fund IX pursuant to the Equity Commitment Letter.

As of the date of this Amendment No. 7, except as set forth in this Schedule 13D, there are no current plans or proposals of the JLL Reporting Persons that relate to or would result in any of the actions identified in Item 4(a) through Item 4(j).

Item 5. Interest in Securities of the Issuer1

Item 5(a) is hereby amended by changing the reference to the percentage of the outstanding shares of the Company’s Common Stock from “25.2%” to “24.8%.”

Item 5(c) is hereby amended by replacing it in its entirety with the following:

No transactions in the Company’s Common Stock were effected by any of the JLL Reporting Persons during the sixty days preceding the date of this Amendment No. 7.
