Exhibit A

USE OF PROCEEDS

We estimate that our net proceeds from this offering will be approximately $151.4 million, after deducting underwriting discounts and commissions and estimated offering expenses payable by us, based on the initial public offering price of $14.00 per share. We intend to use the net proceeds from this offering as follows:

• $2 million to make a one-time payment to Lone Star in consideration for the termination of our Asset Advisory Agreement with certain affiliates of Lone Star upon consummation of this offering as described under “Certain Relationships and Related Party Transactions—Relationships with Lone Star and Affiliates—Asset Advisory Fees”;

• to repay $149.4 million under the Second Lien Credit Agreement; and

• the remainder for general corporate purposes.

The terms of our First and Second Lien Credit Agreements, including the interest rates and maturities thereof, are described in detail under “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Credit Facilities.” The proceeds received under the First and Second Lien Credit Agreements were used to fund a portion of the acquisition of the gypsum division of Lafarge and to make a $130 million distribution to Lone Star.

Credit Suisse Securities (USA) LLC and RBC Capital Markets, LLC, each of whom are underwriters in this offering, or their affiliates, will receive more than 5% of the net proceeds of this offering in connection with the prepayment of a portion of our first and second lien credit facilities. Accordingly, this offering is being made in compliance with the requirements of FINRA Rule 5121. See “Underwriting—Conflicts of Interest.”

The selling stockholder will receive approximately $24.7 million in gross proceeds from this offering if the underwriters exercise in full their option to purchase up to 1,764,750 additional shares of our common stock. We will not receive any proceeds from the sale of shares by the selling stockholder.

Pending use of the net proceeds from this offering described above, we may invest the net proceeds in short- and intermediate-term interest-bearing obligations, investment-grade instruments, certificates of deposit or direct or guaranteed obligations of the United States government.
