SCHEDULE 13D/A This Amendment No. 2 to Schedule 13D (the "Amendment") is being filed on behalf of Jayhawk Institutional Partners, L.P., a Delaware limited partnership ("Jayhawk Institutional"), Jayhawk Investments, L.P., a Delaware limited partnership ("Jayhawk Investments"), their general partner, Jayhawk Capital Management, L.L.C., a Delaware limited liability company ("Jayhawk"), and its manager, Kent C. McCarthy. This Schedule 13D amends the initial statement on Schedule 13D (the "Original 13D") relating to shares of common stock of LSB Industries, Inc., a Delaware corporation (the "Issuer") as filed with the Securities and Exchange Commission (the "Commission") on January 18, 2001, as amended by Amendment No. 1 filed with the Commission on March 22, 2002 (the "Original 13D"). The Original 13D is hereby amended as follows: Item 3. Source and Amount of Funds Item 3 of the Original 13D is hereby amended and restated in its entirety to read as follows: As of February 18, 2002, Jayhawk Investments had invested $768,760 in shares of Common Stock and shares of $3.25 Convertible Exchangeable Class C Preferred Stock ("Class C Preferred Stock"); Jayhawk Institutional had invested $1,388,502 in shares of Common Stock and Class C Preferred Stock; and Mr. McCarthy had invested $435,935 in shares of Common Stock and Class C Preferred Stock. The above amounts include any brokerage commissions incurred in the investments. The source of these funds was the working capital of each entity and the personal funds of Mr. McCarthy, and reported as such in Amendment No. 1 to the Original 13D filed March 22, 2002 (Amendment No. 1). On March 27, 2003, Jayhawk Institutional purchased 450,000 shares of Common Stock and warrants to purchase 112,500 shares of Common Stock for an aggregate purchase price of $1,570,500. The source of funds for this transaction was the working capital of Jayhawk Institutional. *Kent McCarthy is the manager and sole member of Jayhawk, the General Partner and Manager for joint filers Jayhawk Institutional and Jayhawk Investments, and non-filer Lucky Henry, L.P., a Delaware Limited Partnership ("Lucky Henry"), an entity formed in 2002. Since February 18, 2002, except for the March 27, 2003 acquisition, Kent McCarthy's over-all beneficial ownership interest in the Issuer did not change from the 16.5% noted in Amendment No. 1, although a small number of shares were sold (2,500 Shares of Common Stock) and a small number of shares were gifted to charity (1,200 Shares of Class C Preferred Stock, Series 2 (the "Class C Preferred Stock")). However, shares of Common Stock and Class C Preferred Stock were transferred between Kent McCarthy, Jayhawk Institutional, Jayhawk Investments and Lucky Henry, with appropriate adjustments noted to capital accounts related to Kent McCarthy and Jayhawk without the direct transfer of any funds. These transfers occurred on May 1, 2002, June 1, 2002 and October 31, 2002, and were not believed to be of such a nature to require the filing of an amendment to the 13D since, as of the date of the transfers, Kent McCarthy and Jayhawk combined were the exclusive partners in Jayhawk Institutional and Lucky Henry, and combined held approximately 99% of the partnerships interests in Jayhawk Investments.

A statement showing all the sales, gifts and transfers by the reporting parties of the Issuers Common Stock and Class C Preferred Stock since February 18, 2002, is attached hereto as Annex A. Item 5.

(b) Mr. McCarthy, as manager of Jayhawk, has the sole power to vote and dispose of the Shares beneficially owned by Jayhawk, Jayhawk Investments, Jayhawk Institutional and Lucky Henry. (c) The transactions made, including sales, gifts and transfers, by Kent McCarthy, Jayhawk, Jayhawk Institutional and Jayhawk Investments in the Issuer's securities since the filing of Amendment No. 1, are listed on Annex A attached hereto and made a part hereof. No other transactions in the Issuer's securities were made by Jayhawk Institutional, Jayhawk Investments, Jayhawk or Mr. McCarthy during the referred to period. (d) Not Applicable. (e) Jayhawk Investments' beneficial ownership in the Issuer dropped below 5% on May 1, 2002, when it transferred Class C Preferred Stock to Jayhawk Institutional and Lucky Henry.
