     Re:  LSB Industries, Inc.; Form S-8 Registration
          Statement; Non-Qualified Stock Option Agreement
          (Daniel L. Ellis); Our File No. 7033.11
          __________________________________________________

Ladies and Gentlemen:

     We are delivering this opinion to you in connection with the
preparation and filing with the Securities and Exchange Commission
(the "Commission") under the Securities Act of 1933, as amended
(the "Act"), of the Registration Statement on Form S-8 (the
"Registration Statement") of LSB Industries, Inc., a Delaware
corporation (the "Company"), for the registration of 25,000 shares
of the Company's common stock, $0.10 par value (the "Common
Stock"), to be issued by the Company pursuant to the Non-Qualified
Stock Option Agreement, dated December 18, 1997, granted to Daniel
L. Ellis, an employee of the Company or the Company's wholly owned
subsidiaries (the "Non-Qualified Agreement").  

     In connection with this opinion, the undersigned has examined
and relied upon such corporate records, certificates, other
documents and questions of law, as we have considered necessary or
appropriate for the purposes of this opinion, including, but not
limited to, the following: 

     (a)  Company's Certificate of Incorporation, as amended;

     (b)  Company's Bylaws, as amended;

     (c)  the Non-Qualified Agreement;

     (d)  Resolutions of the Board of Directors of the Company,
          dated December 18, 1997;

     (e)  Certificate of Good Standing of the Company issued
          by the Secretary of State of Delaware, on July 23,
          1998;

     (f)  Registration Statement; and

     (g)  Summary Information regarding the Non-Qualified Agreement.

     In our examination, we have assumed the genuineness of all
signatures, the legal capacity of all persons, the authenticity of
all documents submitted as originals, the conformity with the
original documents of all documents submitted as certified or
photostatic copies, and the authenticity of the originals of such
copies.  We have further assumed that any shares of the Company's
Common Stock to be issued under the Non-Qualified Agreement will have 
been issued pursuant to the terms of the Non-Qualified Agreement and 
will have been registered in accordance with the Act, absent the 
application of an exemption from registration, prior to the issuance 
of such shares.

     In reliance upon and based on such examination and review, we
are of the opinion that, when the Registration Statement becomes
effective pursuant to the rules and regulations of the Commission,
the 25,000 shares of Common Stock which may be issued pursuant to
the Non-Qualified Agreement will constitute, when purchased and issued 
pursuant to the terms of the Non-Qualified Agreement, duly authorized, 
validly issued, fully paid and nonassessable shares of Common Stock of
the Company.

     We hereby consent to the filing of this opinion as Exhibit 5.1
to the Registration Statement and to the reference to Conner &
Winters, a Professional Corporation, in Item 5 "Interests of Named
Experts and Counsel" of the Registration Statement.  However,
in rendering this opinion, we do not admit that we are acting
within the category of persons whose consent is required under
Section 7 of the Act or the rules and regulations of the Act.

                                   Very truly yours,

                                   CONNER & WINTERS,
                                   a Professional Corporation

                                   /s/ Conner & Winters, P. C.
