Introduction

This Schedule 13D is reporting matters with respect to Jack E. Golsen (Chief Executive Officer and Chairman of the Board of the issuer), Sylvia H. Golsen, Barry H. Golsen (President and member of the Board of Directors of the issuer), Steven J. Golsen, Linda Golsen Rappaport, SBL Corporation ("SBL"), and Golsen Petroleum Corpor-ation ("GPC"), which is a wholly owned subsidiary of SBL. See Note 2 below and Item 4 hereof as to Linda Golsen Rappaport.

This statement constitutes Amendment No. 33 to the Schedule 13D dated October 7, 1985, as amended (the "Schedule 13D"), relating to the common stock, par value $.10 a share ("Common Stock") of LSB Industries, Inc. (the "Company"). All terms not otherwise defined herein shall have the meanings ascribed in the Schedule 13D. This Amendment No. 33 is being filed as a result of a change in the facts contained in the Schedule 13D described below.

 
1.
On March 13, 2007, GPC exchanged 26,467 shares of the Company’s $3.25 Convertible Exchangeable Preferred Stock, Series 2 (the “Series 2 Preferred”) for 195,855 shares of the Company’s Common Stock pursuant to the terms of the offer to exchange conducted by the Company in accordance with the Schedule TO and exhibits thereto filed by the Company with the Securities and Exchange Commission (“SEC”) on February 9, 2007 (the “Offer to Exchange”).

 
2.
As described in Item 4 of this Amendment 33, Linda Golsen Rappaport is no longer a reporting person under this Schedule 13D and will no longer file as a reporting person with respect to this Schedule 13D unless Rappaport’s beneficial interest in the Common Stock or the Series 2 Preferred increases to 5% or more.

 
3.
As noted in Item 5(b), below, the outstanding common stock of SBL is owned by Sylvia H. Golsen (40%), Barry H. Golsen (20%), Steven J. Golsen (20%), and Linda Golsen Rappaport (20%). The reporting of such individuals’ beneficial ownership over the Company’s securities held by SBL and its wholly owned subsidiary, GPC, has been revised to reflect each person’s proportionate interest in SBL, based on their respective percentage ownership of SBL’s outstanding common stock. As of March 29, 2007, Jack E. Golsen and Barry H. Golsen were the sole directors and officers of SBL and GPC, and as such, possess voting and dispositive power over the Company’s securities held by SBL and GPC.

As disclosed in Item 5(c), GPC tendered to the Company 26,467 shares of Series 2 Preferred owned by GPC in consideration for the 195,855 shares of Common Stock acquired by GPC in the Offer to Exchange.

Item 4.
Purpose of Transaction.
 
The reporting persons do not presently have any plans or proposals required to be reported under Item 4 of this Schedule 13D, except as described below.
 
Offer to Exchange.
 
As described in Amendment No. 32 to the Schedule 13D, filed with the SEC on January 4, 2007, the Company entered into an Agreement (the “Agreement”) on November 10, 2006, with Kent C. McCarthy, Jayhawk Capital Management, L.L.C., Jayhawk Institutional Partners, L.P., and Jayhawk Investments, L.P. (collectively, the “Jayhawk Group”). The Agreement provides that if the Company undertakes, in its sole discretion, within one year from the date of the Agreement, a tender or exchange offer for the Series 2 Preferred, the Jayhawk Group will (a) tender or exchange an aggregate total of only 180,450 shares of the Series 2 Preferred owned by the Jayhawk Group and (b) waive their rights to all accrued and unpaid dividends on the Series 2 Preferred tendered or exchanged.
 
Page 10 of 24 Pages

 
 
CUSIP NO. 5021600-10-4

The obligations of the Jayhawk Group described in the foregoing clauses (a) and (b) were subject to certain conditions, including without limitation: (i) the approval by the holders of the Common Stock and Series 2 Preferred of certain amendments to the Certificate of Designations of the Series 2 Preferred as described below and (ii) SBL and GPC shall only exchange or tender 26,467 shares of the 49,550 shares of Series 2 Preferred beneficially owned by them.

The Agreement also provided that the Jayhawk Group would vote its shares of Common Stock and Series 2 Preferred to amend the Certificate of Designations of the Series 2 Preferred to (a) allow the Company to acquire shares of its Common Stock for a period of five years from the date of completion of the tender or exchange offer, without the approval of the holders of the Series 2 Preferred, notwithstanding that accrued and unpaid dividends may exist with respect to the Series 2 Preferred, and (b) provide that the existing right of the holders of Series 2 Preferred to elect two directors to the Company’s Board of Directors when dividends on the Series 2 Preferred are unpaid may be exercised only if and so long as at least 140,000 shares of Series 2 Preferred remain issued and outstanding.

The foregoing is a summary of the material terms of the Agreement. The above discussion is qualified in its entirety by reference to the Agreement, a copy of which is filed as Exhibit 99.19 to Amendment No. 32 to this Schedule 13D. The Jayhawk Agreement was previously disclosed by the Company in its Form 8-K, filed with the Securities and Exchange Commission (“SEC”)on November 14, 2006, as amended by the Form 8-K/A, filed with the SEC on November 21, 2006.

On February 9, 2007, the Company commenced the Offer to Exchange, which provided that the Company would issue 7.4 shares of Common Stock for each validly tendered and accepted share of Series 2 Preferred. Of the 499,102 shares of Series 2 Preferred outstanding on that date, 309,807 shares were eligible to participate in the Offer to Exchange. 193,295 shares of outstanding Series 2 Preferred were held by GPC (14,033 shares), the Jayhawk Group and others.

The Exchange Offer expired on Monday, March 12, 2007 (the “Expiration Date”). On March 13, 2007, the Company
 
Page 11 of 24 Pages

 
 
CUSIP NO. 5021600-10-4
 
announced the acceptance for exchange of 305,807 shares of Series 2 Preferred that were validly tendered and not withdrawn as of the Expiration Date, and issued a total of 2,262,971 shares of its common stock in exchange for such shares of Series 2 Preferred. Following the closing of the Offer to Exchange, a total of 193,295 shares of Series 2 Preferred remained outstanding at the Expiration Date, of which 9,050 shares are held by SBL Corporation and 14,033 are held by Golsen Petroleum Corporation.

Rappaport.
Linda Golsen Rappaport (“Rappaport”) is the owner of 20% of the issued and outstanding stock of SBL Corporation (“SBL), which is the beneficial owner of (a) 2,679,313 shares of Common Stock, representing 13.16% of the LSB’s outstanding Common Stock as of March 19, 2007, and (b) 23,083 shares of Series 2 Preferred, representing 11.94% of the outstanding Series 2 Preferred as of such date. Rappaport’s proportionate ownership of the Common Stock and Series 2 Preferred beneficially owned by SBL is 535,836 shares of Common Stock, representing 2.73% of the Company’s Common Stock, and 4,617 shares of Series 2 Preferred representing 2.39% of the Company’s outstanding Series 2 Preferred. Prior to March 29, 2007, Rappaport was one of five directors of SBL and one of five officers of SBL. On March 29, 2007, Rappaport ceased being an officer or director of SBL. Rappaport currently has no voting or dispositive power over the Common Stock and Series 2 Preferred beneficially owned by SBL, which includes the shares beneficially owned by SBL’s wholly owned subsidiary and Series 2 Preferred, Golsen Petroleum Corporation (“GPC”), and such Common Stock is not beneficially owned by Rappaport within the meaning of Rule 13d-3 of the Securities and Exchange Act of 1934 (the “Exchange Act”). As a result, Rappaport owns less than 5% of both the Common Stock and the Series 2 Preferred and is not subject to the requirement to file a Schedule 13D.

Rappaport will no longer file as a reporting person with respect to this Schedule 13D, unless Rappaport’s beneficial interest in the Common Stock or Series 2 Preferred increases to 5% or more. In addition, because Rappaport does not beneficially own more than 10% of the outstanding shares of any class of equity security of LSB that is registered pursuant to Section 12 of the Exchange Act, Rappaport will no longer file reports on Forms 3, 4, or 5 pursuant to Section 16(a) of the Exchange Act,

 unless Rappaport’s beneficial ownership increases to 10% or more.
