                           ARTICLE II
                      RIGHTS IN COLLATERAL

     2.1   Priorities  Regarding  Collateral.  Until  the  Senior
Indebtedness has been finally and irrevocably paid  in  full  and
the commitments of Senior Creditor under the Loan Agreement shall
have  terminated  as  provided herein, any  and  every  lien  and
security interest in the Collateral in favor of or held  for  the
benefit  of the Senior Creditor has and shall have priority  over
any  lien  or security interest that Subordinated Creditor  might
have  or  acquire in the Collateral notwithstanding any statement
or provision contained in the Subordinated Documents or otherwise
to  the  contrary and irrespective of the time or order of filing
or  recording of financing statements, deeds of trust,  mortgages
or  other  notices  of security interests, liens  or  assignments
granted  pursuant thereto, and irrespective of anything contained
in  any  filing  or agreement to which any party  hereto  or  its
respective  successors  and assigns may now  or  hereafter  be  a
party,  and  irrespective of the ordinary rules  for  determining
priorities under the Uniform Commercial Code or under  any  other
law  governing the relative priorities of secured creditors.  Any
lien  or  security  interest  of  Subordinated  Creditor  in  the
Collateral and any and all rights of Subordinated Creditor to the
Collateral  are  and  shall be inferior and  subordinate  to  the
rights  of Senior Creditor thereto. Until the Senior Indebtedness
has been finally and irrevocably paid in full and the commitments
of Senior Creditor under the Loan Agreement shall have terminated
as  provided  herein, Subordinated Creditor  shall  not  make  or
permit any assignment, transfer, pledge or disposition of all  or
any  part of the Subordinated Indebtedness (or any collateral  or
other security for the Subordinated Indebtedness).

     2.2   Management of Collateral.  Senior Creditor shall  have
the  exclusive right to manage, perform and enforce the terms  of
the  Senior Documents with respect to the Collateral, to exercise
and enforce all privileges and rights thereunder according to its
discretion  and the exercise of its business judgment, including,
but  not  limited  to,  the exclusive right  to  take  or  retake
possession  of  the  Collateral and to hold,  prepare  for  sale,
process,  sell,  lease, dispose of, or liquidate the  Collateral,
pursuant to a foreclosure or otherwise.  Notwithstanding anything
to   the  contrary  contained  in  any  document,  instrument  or
agreement   evidencing,   securing  or  otherwise   executed   in
connection  with the incurrence of the Subordinated Indebtedness,
only  the  Senior Creditor shall have the right  to  restrict  or
permit,  or  approve or disapprove, the sale, transfer  or  other
disposition  of Collateral.  Accordingly, should Senior  Creditor
elect to exercise its rights and remedies with respect to any  of
the  Collateral,  Senior Creditor may proceed to  do  so  without
regard to any interest of Subordinated Creditor, and Subordinated
Creditor  waives  any  claims that it  may  have  against  Senior
Creditor  for  any  disposition of the Collateral.   Subordinated
Creditor  agrees, whether or not a default has  occurred  in  the
payment  of  any  indebtedness or the performance  of  any  other
obligations  to it, that any liens on and security  interests  in
the  Collateral  or any portion thereof that  it  might  have  or
acquire  shall automatically be fully released with respect  only
to  the  purchaser(s) of such Collateral, as to all  indebtedness
and  other  obligations  secured thereby  owing  to  Subordinated
Creditor  if  and when Senior Creditor releases its lien  in  and
security  interest  on  such Collateral or any  portion  thereof,
provided,  however,  that  after  satisfaction  in  full  of  all
Obligations, the remaining proceeds, if any, shall be payable  to
the  parties  legally  entitled thereto,  including  Subordinated
Creditor  (giving  effect  to  Subordinated  Creditor's  Security
Interest in the Collateral).

                           ARTICLE III
                            PROCEEDS

     3.1   Distribution of Proceeds of Collateral.  At  any  time
during  which  (i)  all  or any part of the  Senior  Indebtedness
remains outstanding, and whether or not the same is then due  and
payable, or (ii) the commitments of the Senior Creditor under the
Loan  Agreement  remain  in effect, the  Proceeds  of  any  sale,
disposition  or  other realization by Senior  Creditor  or  other
party hereto (or any agent therefor) upon all or any part of  the
Collateral  shall be applied in the following order of priorities
irrespective of the application of any rule of law or the  defect
or  impairment of any Senior Document, Subordinated  Document  or
security interest, lien or assignment thereunder:

     first, to  the  payment of all costs and expenses of  Senior
            Creditor  and/or  its  agent  or  agents  (including,
            without  limitation, the reasonable fees and expenses
            of   counsel   to   Senior  Creditor)   incurred   in
            connection  with the collection of such  Proceeds  or
            the  protection of the rights and interests of Senior
            Creditor therein;

     second,to  the payment in full of all Senior Indebtedness in
            such order as Senior Creditor shall determine in  its
            sole discretion; and

     finally,     to  pay  any  surplus  then  remaining  to  the
            parties  legally  entitled  thereto,  including   the
            Subordinated  Creditor, the owner of  the  Collateral
            or  its  successors  or assigns  or  as  a  court  of
            competent jurisdiction may direct.

     3.2   Contingent Obligations.  For purposes of  distributing
the  Proceeds  of  Collateral pursuant to this Article  III,  the
portion  of  Senior Indebtedness consisting of loans or  advances
not  yet  made  by Senior Creditor to Borrower under  the  Senior
Documents   shall   be   considered  Senior   Indebtedness   then
outstanding,  and  the Senior Creditor shall have  the  right  to
retain,  in a cash collateral account, cash collateral  equal  to
the  amount thereof which Senior Creditor determines, in its sole
discretion, may arise or exist from time to time.

     3.3   Holding  of  Proceeds  in Trust.   In  the  event  the
Subordinated Creditor (or an affiliate thereof) or any  party  to
this  Agreement other than Senior Creditor receives the  Proceeds
of the Collateral, such party shall be deemed to hold all of such
Proceeds  in trust for the benefit of Senior Creditor  until  the
application  thereof in accordance with Section 3.1  hereof.   No
party  to  this  Agreement shall seek to challenge the  validity,
enforceability,  priority or perfection  of  any  of  the  Senior
Documents  if the purpose or effect thereof would in  any  manner
defeat  or  delay  the  distribution  of  the  Proceeds  of   any
Collateral in the manner set forth in Section 3.1 hereof.

                           ARTICLE IV
                          SUBORDINATION

     Subordinated   Creditor  covenants  and  agrees   that   the
Subordinated  Indebtedness, howsoever evidenced and  whether  now

     expenses   and/or   obligations  now  or   hereafter   owing
     thereunder, and the Senior Creditor's commitments under  the
     Loan  Agreement  shall have terminated  as  provided  herein
     before  any  payment or Distribution (other  than  Permitted
     Payments  (as defined below)) of any character,  whether  in
     cash, securities or other property, shall be made on account
     of  the Subordinated Indebtedness or otherwise to or for the
     benefit  of  the  Subordinated Creditor in  respect  of  the
     Subordinated  Indebtedness; and any payment or  Distribution
     of  any  character,  whether in cash,  securities  or  other
     property,  which would otherwise, but for the provisions  of

     Subordinated  Indebtedness or otherwise  shall  be  paid  or
     delivered  directly to the holder of the Senior Indebtedness
     (or  its  duly  authorized representatives), until  all  the
     Senior Indebtedness shall have been irrevocably paid in full
     and   the  Senior  Creditor's  commitments  under  the  Loan
     Agreement shall have terminated as provided herein.

     scheduled  (i.e.  uncollected  and  not  prepaid)   interest

     promissory  notes of Borrower to LSB Industries,  Inc.,  one

          default  or  event of default that is continuing  under
          any  of  the  Senior Indebtedness or any of the  Senior
          Documents, or an event or condition which with  notice,
          lapse  of  time  or  the making of such  payment  would
          constitute a default or event of default under  any  of
          the foregoing;

               (ii) Borrower's Excess Availability (as defined in
          the  Loan Agreement) shall be greater than or equal  to

          each Permitted Payment;

               (iii)       Subordinated   Creditor   shall   have

               (v)    the  Senior  Creditor,  on  or  before  the
          fifteenth  (15th) day preceding the date  of  any  such
          payment, shall have received a certificate, executed by
          the Chief Executive Officer and Chief Financial Officer
          of the of Borrower, which certifies, in form, substance
          and  detail satisfactory to the Senior Creditor in  its
          sole   discretion,   that  the   foregoing   conditions
          precedent  to any payment to the Subordinated  Creditor
          as  set  forth  in  subparagraph (b)(i),  (b)(ii),  and
          (b)(iii) of this Article IV have been satisfied.

     Documents  and further agrees not to exercise any  right  or
     remedy  or take any enforcement action with respect  to  any
     default  or  event  of  default on any of  the  Subordinated
     Indebtedness  or otherwise or under any of the  Subordinated

     commitments  under the Loan Agreement shall have  terminated
     as  provided herein.  Without limiting any of the foregoing,

     the  Subordinated  Creditor  as  a  result  of  any  of  the
     prohibitions, restrictions or limitations set forth in  this
     Agreement  shall not constitute the basis for a  default  or
     event  of default on any Subordinated Indebtedness or  under
     any Subordinated Documents.  An Event of Default (as defined
     in the Loan Agreement) under the Loan Agreement shall not be

     Notes.

     Subordinated  Indebtedness  (except  for  the  account   and
     benefit of Senior Creditor, which shall be held in trust for
     Senior  Creditor,  or  except as specifically  permitted  in
     Subparagraph (b) of this Article IV) until such time as  the
     Senior Indebtedness has been finally and irrevocably paid in
     full  and the commitments of Senior Creditor under the  Loan
     Agreement shall have terminated as provided herein.

          (e)   Without  affecting  the  Subordinated  Creditor's
     obligations set forth in this Agreement not to exercise  any
     remedy   as   set  forth  in  this  Article  IV  under   the
     circumstances  described  herein,  in  the  event  that  the
     Subordinated  Creditor exercises any remedy permitted  under
     applicable  law  with  respect  to  any  of  the  assets  or
     properties of Borrower or receives any other payment of  any
     character, whether in cash, securities, or other properties,
     that  would, but for the provisions of this Article  IV,  be
     payable  or  deliverable  in  respect  of  the  Subordinated
     Indebtedness,  such  cash, securities  or  other  properties
     shall be held in trust for the benefit of the holder of  the
     Senior  Indebtedness and shall be paid or delivered  to  the
     holder   of  the  Senior  Indebtedness  (or  its  authorized
     representatives), in the proportions in which it holds same,
     until  all the Senior Indebtedness shall have been  paid  in
     full  and  the Senior Creditor's commitments under the  Loan
     Agreement shall have terminated as provided herein.

          (f)   The  provisions  of this Agreement  are  and  are
     intended  solely  for the purpose of defining  the  relative
     rights  of  the holder of the Subordinated Indebtedness,  on
     the  one hand, and the holder of the Senior Indebtedness  on
     the  other  hand.   Nothing contained in this  Agreement  is
     intended  to  or shall impair, as between Borrower  and  the
     holder  of the Subordinated Indebtedness, the obligation  of
     Borrower which is absolute and unconditional, to pay to  the
     holder   of  the  Subordinated  Indebtedness  the  principal
     thereof  and  interest thereon as and when  the  same  shall
     become due and payable in accordance with its terms,  or  is
     intended  to  or  shall affect the relative  rights  against
     Borrower of the holder of the Senior Indebtedness.

          (g)  No right of any present or future holder of any of
     the  Senior  Indebtedness to enforce  the  subordination  as
     herein  provided shall at any time in any way be  prejudiced
     or  impaired  by any act or failure to act on  the  part  of
     Borrower  or by any act in good faith or failure to  act  in
     good  faith  by any such holder, or by any noncompliance  by
     Borrower  with  the covenants, agreements and conditions  of
     the  Subordinated Indebtedness, regardless of any  knowledge
     thereof  any  such  holder may have or be otherwise  charged
     with.

          (h)   Senior  Creditor  shall  have  no  obligation  to
     preserve  the  rights of the Collateral  against  any  prior
     parties  or to marshal any of the Collateral for the benefit
     of any Person.

                            ARTICLE V
                  PROHIBITION OF DISTRIBUTIONS

     Except  as may be expressly permitted pursuant to  the  Loan
Agreement,  Borrower hereby agrees that it will not declare,  pay
or  make any Distribution with respect to the Borrower Stock  or,
otherwise  to any holder of the Borrower Stock.  Until such  time
as  the  Senior Indebtedness has been paid in full and the Senior

     other similar laws affecting creditors rights generally  and
     except   as   enforceability  may  be  limited  by   general

     in equity); and

          (c)   Subordinated Creditor is the only holder  of  the
     indebtedness evidenced by the Subordinated Notes.

     7.2   Additional Representations and Warranty.  Subordinated

definitive  version of such documents, instruments or  agreements
will be in substantial conformity therewith.

                          ARTICLE VIII
                CONSENT OF SUBORDINATED CREDITOR

     Subordinated  Creditor hereby consents to the execution  and
delivery  of  the Senior Documents and any borrowings  thereunder
and  agrees  that the performance (including, without limitation,
the  making  of future borrowings) by Borrower of its obligations
under  the Senior Documents will not constitute a default  or  an
event  of default under the Subordinated Documents.  Subordinated
Creditor  further  consents to and covenants  that,  without  the
necessity  of  any  reservation of  rights  against  Subordinated
Creditor, and without notice to or further assent by Subordinated
Creditor,  (a) any demand for payment of any Senior  Indebtedness
may  be rescinded in whole or in part and any Senior Indebtedness
may  be  continued, and the Senior Indebtedness, or the liability
of  Borrower or any other Person upon or for any part thereof, or
any  collateral security or guaranty therefor or right of  offset
with  respect thereto, or any obligation or liability of Borrower
or  any other Person under the Senior Documents may, from time to
time,  in  whole  or  in  part, be renewed,  extended,  modified,
accelerated,  compromised, waived and surrendered,  or  released,
and   (b)  the  Senior  Documents,  any  document  or  instrument
evidencing  or governing the terms of the Senior Indebtedness  or
any  collateral security documents or guaranties or documents  in
connection  therewith may be amended, modified,  supplemented  or
terminated,  in whole or in part, as the Senior Creditor  or  its
agent  may  deem advisable from time to time, and any  collateral
security  at any time held for the benefit of the Senior Creditor
for  the  payment of any of the Senior Indebtedness may be  sold,
exchanged,  waived, surrendered or released,  in  each  case  all
without  notice to or further assent by the Subordinated Creditor
which  will  remain bound under this Agreement, and  all  without
impairing,  abridging, releasing or affecting  the  subordination
provided for herein, notwithstanding any such renewal, extension,
modification,  acceleration, compromise,  amendment,  supplement,
termination,  sale, exchange, waiver, surrender or release.   The
Subordinated Creditor waives any and all notice of the  creation,
renewal, extension, subsequent advance or accrual of any  of  the
Senior  Indebtedness and notice of or proof of  reliance  by  the
Senior  Creditor upon this Agreement, and the Senior Indebtedness
shall conclusively be deemed to have been created, contracted  or
incurred  in  reliance  upon  this Agreement,  and  all  dealings
between Borrower and the Senior Creditor have been deemed to have
been   consummated   in  reliance  upon  this   Agreement.    The
Subordinated  Creditor acknowledges and agrees  that  the  Senior
Creditor  has relied upon the subordination and consent  provided
for  herein  in  entering into the Senior Loan Documents  and  in
providing  for  the  credit facilities  described  therein.   The
Subordinated  Creditor waives notice of or proof of  reliance  on
this  Agreement  and protest, demand for payment  and  notice  of
default.  Any agreements, documents or instruments which  at  any
time  evidence the Subordinated Indebtedness or any part  thereof
shall be marked with a legend stating that payment thereunder  is
subject  to  the  terms and provisions of  this  Agreement.   The
Subordinated  Creditor  agrees  that  it  shall  not,  under  any
circumstances,  take or initiate any action or  proceeding  under
any  federal or state bankruptcy or insolvency law, or any  other
reorganization,  liquidation, receivership or similar  action  or
proceeding  involving Borrower without the prior written  consent
of  every  Senior  Creditor,  which consent  may  be  granted  or
withheld  by each Senior Creditor in such Senior Creditor's  sole
and absolute discretion.

                           ARTICLE IX
                      BORROWER'S AGREEMENT

     The  Borrower  hereby  acknowledges  that  the  Subordinated
Indebtedness is payable as stated herein, and agrees to  make  no
payment   of   principal  of  or  interest  on  the  Subordinated
Indebtedness so long as the Borrower shall be indebted to  Senior
Creditor,  except  (i) such payments as may  be  made  to  Senior
Creditor,  (ii)  such  payments as may be  made  with  the  prior
written  consent of Senior Creditor, and (iii) such  payments  as
are  permitted  by Article IV herein.  If (a) the Borrower  makes
any  other payment of the Subordinated Indebtedness, except  such
payments as are permitted by Article IV herein, (b) any  term  of
this  Agreement is breached by the Borrower, or (c) the  Borrower
fails  to make any payment of the Subordinated Indebtedness  when
due  after Senior Creditor has given its written consent  to  the
making  of  such  payment,  then,  notwithstanding  any  contrary
provisions  of the Loan Agreement, Senior Creditor  may,  at  its
sole   election,  declare  all  or  any  portion  of  the  Senior
Indebtedness to be immediately due and payable without demand  or
notice of any kind.

                            ARTICLE X
              PROVISIONS TO APPLY AFTER BANKRUPTCY

     The  provisions  of this Agreement shall  continue  in  full
force  and  effect, notwithstanding the commencement  of  a  case
under  Title  11  of  the United States Code, as  amended  and/or
superseded (the "Federal Bankruptcy Code") by or against Borrower
or  any  of  its  property.  In furtherance of the foregoing,  if
Subordinated Creditor receives any property of, or payments  from
Borrower  after the commencement of such a case on account  of  a
secured  claim  which  is  subordinated  by  the  terms  of  this
Agreement   (whether   as  "adequate  protection"   payments   or
otherwise),  Subordinated Creditor shall  immediately  turn  such
property or payments over to the Senior Creditor for distribution
by   it   in   accordance  with  the  applicable  provisions   of
Article  III.   To the extent that Subordinated Creditor  has  or
acquires  any  rights under Section 363 or  Section  364  of  the
Federal  Bankruptcy Code with respect to collateral, Subordinated
Creditor  hereby  agrees not to assert such  rights  without  the
prior  written consent of the Senior Creditor.  The  Subordinated
Creditor  hereby  grants to the Senior Creditor  the  right,  but
Senior  Creditor shall not be obligated, to file, prove and  vote
claims  on  account  of  the  Subordinated  Indebtedness  in  any
receivership, bankruptcy, or other proceeding under  the  Federal
Bankruptcy   Code   commenced  by  or  against   Borrower.    The
Subordinated  Creditor  shall not prove  or  vote  any  claim  on
account  of  the  Subordinated Indebtedness in any  receivership,
bankruptcy, or other proceeding under the Federal Bankruptcy Code
commenced  by  or  against Borrower in a manner  which  adversely
effects  the rights, claims and interests of the Senior  Creditor
now  existing  or hereafter arising concerning the Collateral  or
against the Borrower.

                           ARTICLE XI
                 NO WAIVER, CUMULATIVE REMEDIES

     No  failure to exercise, and no delay in exercising  on  the
part of Senior Creditor, any right, power or privilege under this
Agreement shall operate as a waiver thereof, nor shall any single
or  partial  exercise by Senior Creditor of any right,  power  or
privilege  under  this Agreement preclude any  other  or  further
exercise  thereof or the exercise of any other  right,  power  or
privilege by Senior Creditor.  The rights and remedies by  Senior
Creditor provided in this Agreement are cumulative and shall  not
be exclusive of any rights or remedies provided by law.
