     Dear Mr. Jones:

     Reference  is  made  to  that certain Loan  Agreement  dated
     October  31, 1994, as amended (the "Agreement") between  DSN
     Corporation,   ("Debtor"),  and  the   CIT   Group/Equipment
     Financing,  Inc. ("CIT").  Debtor has advised CIT  that  LSB
     Industries Inc., a guarantor of Debtor's obligations to  CIT
     were not in compliance with certain covenants as of December
     31, 1999.

     Debtor  has requested, that notwithstanding anything to  the
     contrary  of the Agreement, that CIT waive the instances  of
     non-compliance through April 1, 2001.

     CIT  hereby waives, as of this date, the above instances  of
     non-compliance  under  the  Agreement  by  acceptance  of  a
     $7,500.00  processing fee.

     All  other terms, conditions and agreements under  the  Loan
     Agreement,  together  with  all schedules,  attachments  and
     amendments  thereto shall remain in full force  and  effect.
     Please  note that Cites willingness to waive this particular
     covenant  violation  should  not  be  interpreted  as  Cites
     agreement  or  willingness to waive any  further  breach  or
     violation of the Agreement.

                               Sincerely,
                                The CIT Group Equipment Financing
     Inc.
