Attention:  Mr. Wayne Deleo

Gentlemen:

     Reference  is  made  to  that  certain  Feedstock  Agreement (the
"Agreement")  dated  April 30, 1987, between Melamine Chemicals,  Inc.
("MCI")  and Triad Nitrogen,  Inc.  ("TNI"),  as  successor  to  First
Mississippi Corporation ("FMC").

     The Agreement provides inter alia that the price for Urea will be
market price as reflected by the weighted average price (excluding all
taxes reflected  therein)  TNI  receives  on  all bulk, prilled and/or
granulated Urea sales, FOB Donaldsonville, Louisiana,  excluding sales
to  MCI,  sales to TNI subsidiaries and intra-company transfers,  less
Five and 00/100 Dollars ($5.00) per ton and that the price and credits
for quantities  of  Anhydrous Ammonia and Anhydrous Ammonia Equivalent
obtained from recycled carbamate delivered under the Agreement will be
the market price as reflected by the weighted average price (excluding
all taxes reflected therein)  TNI  receives  on  all Anhydrous Ammonia
sales FOB Donaldsonville, Louisiana, excluding sales  to MCI and sales
to TNI subsidiaries or intra-company transfers, less Five  and  00/100
Dollars ($5.00) per ton.

     TNI  intends  to sell substantially all of the Urea and Anhydrous
Ammonia produced by  it at Donaldsonville, Louisiana, to an affiliated
entity, Mississippi Chemical  Company,  L.P. ("MCCLP").  The prices to
be paid by MCCLP are established based on  a  contract  formula agreed
upon  by  MCCLP  and  TNI and may vary from prevailing market  prices.
MCCLP will resell Urea and Anhydrous Ammonia purchased from TNI to its
customers in industrial and agricultural markets at  prevailing market
prices.

     This Letter Agreement  confirms  our  understanding and agreement
that the price for quantities of urea sold under the Agreement will be
the market price as reflected by the weighted average price (excluding
all taxes reflected therein) that MCCLP receives  on all bulk, prilled
and/or granulated  Urea sales FOB Donaldsonville, Louisiana, excluding
sales  to  MCI,  TNI or MCCLP affiliates, subsidiaries,  partners  and
intra-company transfers, less Five and 00/100 Dollars ($5.00) per ton.
The average price shall be determined quarterly by utilizing the sales
from the immediately  preceding  calendar  quarter  in which MCCLP has
sales.   In  the event that either party feels the volume  of  MCCLP's
sales is not sufficient  to  accurately  reflect  market price for the
given  period, then either party may request a meeting  to  discuss  a
pricing  change  using  appropriate industry indices.  However, in the
absence of mutual written  agreement by the parties otherwise, MCCLP's
weighted average price as outlined  above  shall  prevail.  The prices
and credits for quantities of Anhydrous Ammonia and  Anhydrous Ammonia
Equivalent  obtained  from  recycled  carbamate  delivered  under  the
Agreement  will  be  the  market  price as reflected by  the  weighted
average  price  (excluding all taxes  reflected  therein)  that  MCCLP
receives on all Anhydrous Ammonia sales FOB Donaldsonville, Louisiana,
excluding  sales  to  MCI,  TNI  or  MCCLP  affiliates,  subsidiaries,
partners and intra-company  transfers,  less  Five  and 00/100 Dollars
($5.00) per ton.  The average price shall be determined  quarterly  by
utilizing the sales from the immediately preceding calendar quarter in
which  MCCLP  has  sales.   In  the  event that either party feels the
volume of MCCLP's sales is not sufficient to accurately reflect market
price for the given period, then either party may request a meeting to
discuss a pricing change using appropriate industry indices.  However,
in the absence of mutual written agreement  by  the parties otherwise,
MCCLP's weighted average price as outlined above shall prevail.

     TNI  shall  cause MCCLP to keep complete and accurate  books  and
records on all sales  on  which  the  price  under  the  Agreement  is
determined  and  to  permit, on request by MCI, an independent auditor
selected by MCI and to  whom  MCCLP shall have no reasonable objection
to examine such books and records  for any period ending not more than
two (2) years prior to such request  to  determine  the correctness of
any  price under the Agreement.  Said auditor shall not  disclose  any
information  relating  to said books or records except his opinions as
to the correctness of such price.

     This Letter Agreement  shall  take  effect on March 31, 1997, for
determination  of  the price of urea and the  price  and  credits  for
anhydrous ammonia for the second quarter of 1997 and for every quarter
thereafter.

     This Letter Agreement  confirms  our  understanding and agreement
that TNI has succeeded to all rights and obligations of Triad, FMC and
MCC  under the Agreement such that the defined  term  "Triad"  in  the
Agreement  now  refers  to  TNI,  and  the  defined  term "FMC" in the
Agreement now means TNI.

     All  capitalized  terms  used  in this Letter Agreement  and  not
otherwise defined, shall have the meanings set forth in the Agreement.

     Except  as  expressly  amended  herein,   all   other  terms  and
conditions shall remain in full force and effect.

     If you are in agreement with the foregoing, please  so  indicated
by  signing  in  the  space  provided  below  and  returning one fully
executed original of this Letter Agreement to us for our files.

                              Very truly yours,

                              TRIAD NITROGEN, INC.
