* The Investor (as defined in the Introduction) beneficially owns, and is the record holder of, 267,829 shares of Junior Preferred and 126,400,000 shares of Common Stock. The Junior Preferred Stock, together with the Common Stock held by the Investor, currently represent 49% of the total voting power of the voting stock of the Issuer (as defined in the Introduction). The Junior Preferred Stock will vote with the Common Stock on an as-converted basis provided that the votes attributable to shares of Junior Preferred Stock held by the Investor, together with votes attributable to shares of Common Stock held by the Investor, cannot exceed 49% of the total voting power of the voting stock of the Issuer. The Junior Preferred Stock is initially convertible into up to 87,812,786.89 shares of Common Stock; however, the Investor is not entitled to convert the Junior Preferred Stock into Common Stock unless after such conversion it would hold no more than 49% of the voting power of the voting stock of the Issuer. Upon a voluntary or involuntary liquidation, dissolution or winding up of the Issuer, the holders of Junior Preferred Stock will receive the amount payable if the Junior Preferred Stock had been converted into Common Stock immediately prior to the liquidating distribution. For such purposes, the as-converted number for the Junior Preferred Stock would be 87,812,786.89 shares of Common Stock, which, together with the 126,400,000 shares of Common Stock held by the Investor, equals approximately 58.8% of the outstanding Common Stock. The Reporting Persons (as defined in the Introduction) share voting power and the power to dispose or direct the disposition of the Common Stock and Junior Preferred Stock held directly by the Investor.

Additionally, on May 20, 2013, the Investor converted 183,000 shares of Junior Preferred Stock into 60,000,000 shares of Common Stock. Following the sale and the conversion both as described above, the Investor beneficially owns, and is the record holder of, 267,829 shares of Junior Preferred Stock and 126,400,000 shares of Common Stock. The Junior Preferred Stock, together with the Common Stock held by the Investor, currently represent 49% of the total voting power of the voting stock of the Issuer. The Junior Preferred Stock will vote with the Common Stock on an as-converted basis provided that the votes attributable to such shares of Junior Preferred Stock held directly by the Investor, together with votes attributable to shares of Common Stock held directly by the Investor, cannot exceed 49% of the total voting power of the voting stock of the Issuer. The Junior Preferred Stock is convertible into up to 87,812,786.89 shares of Common Stock; however, the Investor is not entitled to convert the Junior Preferred Stock into Common Stock unless after such conversion it would hold no more than 49% of the voting power of the voting stock of the Issuer. Upon a voluntary or involuntary liquidation, dissolution or winding up of the Issuer, the holders of Junior Preferred Stock will receive the amount payable if the Junior Preferred Stock had been converted into Common Stock immediately prior to the liquidating distribution. For such purposes, the as-converted number for the Junior Preferred Stock would be 87,812,786.89 shares of Common Stock, which, together with the 126,400,000 shares of Common Stock held by the Investor, equals approximately 58.8% of the outstanding Common Stock based on the outstanding Common Stock reported in the prospectus supplement filed on May 16, 2013. The Reporting Persons share voting power and the power to dispose or direct the disposition of the Common Stock and Junior Preferred Stock held directly by the Investor.

Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.

Item 6 is amended and supplemented by adding the following:

In connection with the underwritten offering described in Item 4 above, the Investor has entered into the Underwriting Agreement, in which it has agreed to, among other things, not effect a Transfer of any shares of Common Stock or other securities convertible into Common Stock (subject to certain exceptions) for up to 90 days from the date of the Underwriting Agreement. The terms of the Underwriting Agreement are hereby incorporated by reference in this Item 6. Additionally, as disclosed in Item 4, David Matlin entered into the Lock-Up Agreement with Credit Suisse, the form of which is attached hereto as Exhibit 12 and incorporated herein by reference.

Re: Standard Pacific Corp.

Ladies and Gentlemen:

The undersigned understands that you, as Underwriter (the “Underwriter”), propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with Standard Pacific Corp., a Delaware corporation (the “Company”), and the Selling Stockholders listed on Schedule I to the Underwriting Agreement, providing for the public offering (the “Public Offering”) of shares of common stock, par value $0.01 per share (“Common Stock”), of the Company (the “Securities”), by you. Capitalized terms used herein and not otherwise defined shall have the meanings set forth in the Underwriting Agreement.

In consideration of your agreement to purchase and make the Public Offering of the Securities, and for other good and valuable consideration receipt of which is hereby acknowledged, the undersigned hereby agrees that, without the prior written consent of the Underwriter, the undersigned will not, during the period ending 90 days after the date of the prospectuses relating to the Public Offering (the “Prospectus”), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock (including without limitation, Common Stock or such other securities which may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission and securities which may be issued upon exercise of a stock option or warrant), or publicly disclose the intention to make any such offer, sale, pledge or disposition, (2) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Common Stock or such other securities convertible into or exercisable or exchangeable for Common Stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise or (3) make any demand for or exercise any right with respect to the registration of any Common Stock or any security convertible into or exercisable or exchangeable for Common Stock, in each case other than (A) the Securities to be sold by the undersigned pursuant to the Underwriting Agreement, (B) transfers of shares of Common Stock as a bona fide gift or gifts, (C) distributions of Common Stock to members or stockholders of the undersigned, (D) in the case of an expiring stock option (including if the undersigned’s services with the Company are terminated during such 90-day period), the sale of Common Stock issuable upon the exercise thereof in an amount limited to the amount necessary to pay any

tax liabilities associated therewith, (E) if the undersigned is an individual, upon the death of the undersigned, transfers of Common Stock by the estate of the undersigned, (F) repurchases of Common Stock by the Company from the undersigned to satisfy tax withholding obligations arising upon the vesting of performance share awards and restricted stock granted to the undersigned prior to the date of this Letter Agreement and (G) any transfer pursuant to a bona fide third party tender offer, merger, consolidation or other similar transaction made to all holders of Common Stock involving a change of control of the Company; provided that in the case of any transfer or distribution pursuant to clause (B) or (C), each donee or distributee shall execute and deliver to the Underwriter a lock-up letter in the form of this paragraph; and provided further that in the case of any transfer or distribution pursuant to clause (B) or (C), no filing by any party (donor, donee, transferor or transferee) under the Securities Exchange Act of 1934, as amended, or other public announcement shall be required or shall be made voluntarily in connection with such transfer or distribution (other than a filing on a Form 5 made after the expiration of the 90-day period referred to above).

In furtherance of the foregoing, the Company, and any duly appointed transfer agent for the registration or transfer of the securities described herein, are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Letter Agreement.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Letter Agreement. All authority herein conferred or agreed to be conferred and any obligations of the undersigned shall be binding upon the successors, assigns, heirs or personal representatives of the undersigned.

Very truly yours,
