State below in reasonable detail the reasons why Forms 10-K, 20-F, 11-K, 10-Q, N-SAR, or the transition report portion thereof, could not be filed within the prescribed time period.

**
As part of the Securities & Exchange Commission's ("SEC") requirement to periodically review Exchange Act reports of reporting issuers, LSB has received a comment letter from the SEC regarding its annual report on Form 10-K for the year ended December 31, 2004, and Forms 10-Q for the quarters ended March 31, 2005 and June 30, 2005.  LSB responded to the comment letter, which resulted in further comments and clarifications being issued by the SEC to LSB regarding such reports.  LSB has responded to the SEC's additional comments and request for clarifications.  LSB and its independent registered accountants, Ernst & Young LLP, are in the process of discussing with the accounting staff of the SEC certain of their comments regarding LSB's Forms 10-K and 10-Q, which could, if not resolved satisfactorily, result in certain changes to LSB's audited 2004 financial statements and accordingly, the 2004 financial data included in LSB's Form 10-Q for the quarter ended September 30, 2005.  As a result, LSB needs additional time to conclude its discussions with the accounting staff of the SEC regarding their comments in order to file its Form 10-Q for the quarter ended September 30, 2005.

(2) Have all other periodic reports required under Section 13 or 15(d) of the Securities Exchange Act of 1934 or Section 30 of the Investment Company Act of 1940 during the preceding 12 months or for such shorter period that the registrant was required to file such report(s) been filed? If answer is no, identify report(s). [ X ] Yes [ ] No ________________________________________________________________________________

(3) Is it anticipated that any significant change in results of operations from the corresponding period for the last fiscal year will be reflected by the earnings statements to be included in the subject report or portion thereof?   [ X ] Yes [ ] No

If so, attach an explanation of the anticipated change, both narratively and quantitatively, and, if appropriate, state the reasons why a reasonable estimate of the results cannot be made.

It is anticipated that net income for the three months ended September 30, 2005 will be approximately $1.7 million as compared to $3.5 million for the same period in 2004. The reduction in 2005 net income as compared to 2004 is primarily due to $4.4 million Gain on extinguishment of debt in 2004 partially offset by a $1.5 million provision for loss on notes receivable.  Due to debt refinancing in 2004, interest expense for the 2005 quarter is approximately $1.1 million greater than interest expense for the 2004 quarter.
