ITEM 1.01        ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

Convertible Notes Underwriting Agreement

On July 31, 2012, Standard Pacific Corp. (the “Company”) entered into an underwriting agreement (the “Notes Underwriting Agreement”), by and among the Company, the subsidiary guarantors party thereto (the “Guarantors”) and J.P. Morgan Securities LLC, Citigroup Global Markets Inc., Credit Suisse Securities (USA) LLC and Merrill Lynch, Pierce, Fenner & Smith Incorporated, as representatives of the several underwriters listed therein (collectively, the “Underwriters”), relating to the sale by the Company of $220,000,000 aggregate principal amount of its 1.25% Senior Convertible Notes due 2032 (the “Firm Notes”), and an additional $33,000,000 aggregate principal amount of 1.25% Senior Convertible Notes due 2032 pursuant to the over-allotment option exercised by the Underwriters (collectively with the Firm Notes, the “Notes”).

Convertible Notes

The Notes will be issued under the indenture, dated as of April 1, 1999 (the “Indenture”), between the Company and The Bank of New York Mellon Trust Company, N.A. (as successor in interest to J.P. Morgan Trust Company, National Association, Bank One Trust Company, N.A. and The First National Bank of Chicago), as trustee (the “Trustee”), as supplemented by an Eighteenth Supplemental Indenture, dated as of August 6, 2012, among the Company, the Guarantors, and the Trustee (the “Eighteenth Supplemental Indenture”). The Notes will be senior unsecured obligations of the Company and will be guaranteed by the Guarantors on a senior unsecured basis.

The Notes will bear interest at a rate of 1.25% per year, payable semiannually in arrears on February 1 and August 1 of each year, beginning on February 1, 2013. The Notes will mature on August 1, 2032, unless earlier converted, redeemed or repurchased. At any time until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert their Notes into shares of the Company’s common stock at an initial conversion rate of 123.7662 shares of common stock per $1,000 principal amount of Notes (which is equal to an initial conversion price of approximately $8.08 per share), subject to adjustment.

The Company may not redeem the Notes prior to August 5, 2017. On or after August 5, 2017 and prior to the maturity date, the Company may redeem for cash all or part of the Notes at a redemption price equal to 100% of the principal amount of the Notes being redeemed, plus accrued but unpaid interest (including additional interest, if any) to, but excluding, the redemption date. On each of August 1, 2017, August 1, 2022 and August 1, 2027, holders of the Notes may require the Company to purchase all or any portion of their Notes for cash at a price equal to 100% of the principal amount of the Notes to be repurchased, plus accrued but unpaid interest (including additional interest, if any) to, but excluding, the repurchase date.

If the Company undergoes a fundamental change (as defined in the Eighteenth Supplemental Indenture), holders of the Notes may, with certain exceptions, require the Company to repurchase any or all of their Notes for cash at a price equal to 100% of the principal amount of the Notes to be repurchased, plus accrued but unpaid interest (including additional interest, if any) to, but excluding, the repurchase date.

Common Stock Underwriting Agreement

In addition, the Company entered into an underwriting agreement with the Underwriters in connection with the concurrent offer and sale by the Company of 12,500,000 shares (the “Shares”) of the Company’s common stock at a price to the public of $5.67 per Share (the “Common Stock Underwriting Agreement”). The Company granted the Underwriters a 30-day option to purchase up to 1,875,000 additional Shares solely to cover over-allotments.

Certain of the Underwriters and their affiliates have provided in the past to the Company and its affiliates certain commercial banking, financial advisory, investment banking and other services in the ordinary course of their business, for which they have received and may continue to receive customary fees and commissions. In particular, affiliates of each of the Underwriters are lenders under the Company’s revolving credit facility. In addition, Merrill Lynch, Pierce, Fenner & Smith Incorporated, an Underwriter, and its affiliates in the aggregate own approximately 5.13% of the Company’s common stock and options convertible into the Company’s common stock.
