the Battery Limits of the EDNC Baytown Plant the Ammonia for
EDNC's use in manufacturing Nitric Acid; provided, however, that
Bayer shall not be obligated to supply EDNC with more than One
Hundred Fifteen percent (115%) of the monthly nameplate
requirements of the EDNC Baytown Plant.  ****  Bayer warrants
that the Ammonia supplied hereunder shall meet the applicable
Ammonia Specifications set forth on the attached Schedule 9. 
Bayer covenants that such Ammonia shall be free of all liens and
encumbrances.  The Ammonia shall be delivered by or on behalf of
Bayer to EDNC at the Battery Limits of the EDNC Baytown Plant via
the Delivery System or other agreed-upon mechanism.  Bayer shall
invoice EDNC monthly for Ammonia provided by Bayer.

    9.2  Supply by EDNC - Subject to the terms of any
ammonia procurement contracts between Bayer and its ammonia
supplier(s) and subject to the satisfactory resolution of any
logistical issues between Bayer and EDNC regarding the
segregation and maintenance of ammonia inventory, the parties
hereby agree that upon EDNC's request the parties will negotiate
in good faith the possibility of the sourcing of ammonia for
third party sales by EDNC on its own behalf (provided, however,
that this clause shall not be interpreted to require Bayer to pay
any premium, increased cost or penalty for Ammonia under its
procurement contracts as a result of such direct sourcing by
EDNC). 

    9.3  Measurement of Ammonia Supplied

         (A)  Metering - EDNC shall install, operate and
maintain, at its expense, metering equipment to measure EDNC's
consumption of the Ammonia supplied by pipeline.  EDNC's readings
will be the basis upon which any charges will be assessed against
EDNC for the consumption of Ammonia.

         (B)  Calibration - EDNC shall calibrate all meters
in accordance with manufacturer's recommendations.  If dual in-
line meters are installed, EDNC shall also calibrate the meters
relative to each other.  EDNC shall designate one meter as the
primary meter from which all readings shall be taken.  The second
meter's readings shall be used during failure, testing or
recalibration of the first meter and to periodically verify the
reading of the first meter.  EDNC shall give Bayer three (3) days
notice of, and the right to observe, the calibration of any
meters installed by EDNC.  EDNC shall recalibrate each meter as
recommended by the manufacturer.  If during any such periodic
recalibration the meter is found to be inaccurate by more than
one-half of one percent (0.50%) of indicated value, or the second
of the dual meters differs by more than one half of one percent
with the first meter, then EDNC shall repair or recalibrate such
meter to the lesser of:  (i) manufacturer's tolerances; or
(ii) plus or minus one-half of one percent (0.50%) of indicated
value.  If a meter is inaccurate by more than one-half of one
percent (0.50%) of indicated value, the party that has benefitted
from the inaccuracy shall refund to the other party one hundred
percent (100%) of the discrepancy, back to the date of the last
calibration or, if identifiable, back to the date of the failure
that triggered the inaccuracy.  If feasible, EDNC shall affix its
seal to each meter after each calibration.  EDNC agrees to
exercise reasonable efforts to conduct all meter readings,
inspections, recalibrations and repairs in a manner that will not
unreasonably interfere with Bayer's operations at the Bayer
Baytown Plant.  EDNC shall also permit Bayer, at Bayer's expense,
to inspect the meters at any time, provided such inspection does
not unreasonably interfere with EDNC's operations at the EDNC
Baytown Plant.


SECTION 10:  UTILITIES

    In accordance with and subject to the terms, conditions
and limitations of the Services Agreement, Bayer shall supply to
EDNC at the Battery Limits of the EDNC Baytown Plant the

    In accordance with and subject to the terms, conditions
and limitations of the Services Agreement, Bayer shall accept at
the Battery Limits of the EDNC Baytown Plant and shall be
responsible for the proper treatment and disposal, in accordance
with all applicable Environmental, Health and Safety Laws, of
certain Waste produced in connection with the operation of the
EDNC Baytown Plant.


SECTION 12:  INTERRUPTION OF AMMONIA, UTILITIES OR NITRIC ACID

    12.1 Interruption of EDNC Feedstock - If Bayer is 
unable to or fails to deliver Ammonia or Utilities to the EDNC
Baytown Plant as required by the Project Agreements, then EDNC
may procure such Ammonia or Utilities elsewhere through any
commercially reasonable source.  Notwithstanding the foregoing,
EDNC may supply such Ammonia and Utilities through the
infrastructure of the Bayer Baytown Plant only with the prior
approval of Bayer, which may not be unreasonably withheld.  Any
procurement by EDNC of Ammonia or Utilities from parties other
than Bayer shall be at EDNC's risk, and shall have no effect on
the warranty made to Bayer by EDNC pursuant to Section 6 hereof. 
If Bayer is unable to or fails to deliver Ammonia or Utilities as
required by the Project Agreements, EDNC's remedy for such
failure is set forth in Section 16 hereof.

    12.2 Interruption of Nitric Acid - If EDNC is unable to
or fails to provide Bayer's monthly Nitric Acid requirements for
the Bayer Baytown Plant and EDNC is unable to provide back-up
supply to Bayer, then Bayer may procure such Nitric Acid
elsewhere through any commercially reasonable source.  EDNC shall
permit Bayer to use EDNC's four (4) spot truck loading and
un-loading rack if Bayer requires use of the same for the receipt
of nitric acid from third party suppliers.  


SECTION 13:  PIPELINE AND DELIVERY SYSTEM CONSTRUCTION AND

    If any EDNC Event of Default is remedied within the
aforementioned cure periods, such EDNC Event of Default shall not
constitute a continuing EDNC Event of Default and this Agreement
shall continue in full force and effect as if said EDNC Event of
Default had not occurred.  The waiver of any EDNC Event of
Default under this Agreement shall not constitute a waiver of any
subsequent EDNC Event of Default.

    16.3 Bayer Events of Default - A "Bayer Event of
Default" shall occur upon the occurrence of any one or more of
the following events, unless the event is caused by EDNC or any

Bayer has undertaken reasonably effective curative measures, in
which case the cure period for such Bayer Event of Default shall
be the number of days reasonably required to effectuate such
cure.

    If any Bayer Event of Default is remedied within the
aforementioned cure periods, such Bayer Event of Default shall
not constitute a continuing Bayer Event of Default and this
Agreement shall continue in full force and effect as if said
Bayer Event of Default had not occurred.  The waiver of any Bayer
Event of Default under this Agreement shall not constitute a
waiver of any subsequent Bayer Event of Default.

    16.5 Bayer Remedies for EDNC Events of Default - The

Bayer upon an occurrence of any one of the following events:

         (A)  Failure by Bayer to complete construction of

that if such failure is by reason of a Force Majeure Event, then
EDNC shall not have the option to terminate this Agreement if
Bayer provides, within sixty (60) days of the occurrence of such

Majeure Event and such plan is reasonably acceptable to EDNC; or

         (B)  A Bayer Event of Default that is not cured

any current Renewal Term;

         (B)  in the event that either Bayer, on the one
hand, or EDNC or El Dorado on the other hand (collectively, "EDNC
Parties") (i) makes an assignment for the benefit of creditors,
becomes insolvent or admits in writing its inability to pay its
debts as they become due, files a voluntary petition in
bankruptcy or a petition seeking reorganization, liquidation,
dissolution or similar relief under any law or regulation; (ii)
either Bayer or one of the EDNC Parties applies for, consents to
or acquiesces in the appointment of a trustee, receiver or
liquidator for itself or any of its property; or (iii) an
involuntary bankruptcy or involuntary insolvency proceeding is
commenced by either Bayer or either of the EDNC Parties and such
involuntary bankruptcy or involuntary insolvency proceeding is
not dismissed within ninety (90) days of its commencement.

    17.4 Effects of Termination

         (A)  In the event that (i) the Term of this
Agreement is not extended beyond either the Initial Term or any
current Renewal Term, (ii) is terminated as a result of an EDNC
Event of Default, (iii) is terminated as a result of a Bayer
Event of Default or (iv) is automatically terminated pursuant to
Section 17.3 hereof, Bayer shall pay to EDNC the appropriate
termination fee (as hereinafter provided); the Project Agreements
shall terminate (except as otherwise provided in Section 17.4(B)
hereof); and all right and interest of EDNC to and under the
Ground Lease and the Leasehold Improvements shall automatically
terminate without further action by Bayer, EDNC or any other
party.  In the case of a termination due to (a) the expiration of
the Initial Term or any Renewal Term, any automatic termination

respect of the Owner Trustee in the case of such a termination. 
Any election by Bayer pursuant to the Bayer Agreement shall not
release EDNC or El Dorado from liability for any deficiencies
EDNC owes pursuant to any of the Project Agreements.  EDNC's
interest in and title to the Leasehold Improvements shall be
transferred to Bayer upon payment to EDNC (or to the Owner
Trustee on behalf of EDNC) of the Expiration Termination Fee, the
EDNC Default Termination Fee or the Bayer Termination Fee,
whichever is applicable.  If the Bayer Default Termination Fee,
the EDNC Default Termination Fee or the Expiration Termination
Fee is a negative number, then EDNC shall pay to Bayer the
deficiency.

         (B)  The termination contemplated by this
Section 17 shall be conditioned upon and subject to the receipt
of any necessary regulatory approvals, including without
limitation the expiration of the waiting period under the Hart-
Scott-Rodino Antitrust Improvements Act of 1976, as amended (if
applicable), and any necessary approvals under the Exon-Florio
Act, as amended (if applicable).  The termination shall be
effective (A) within thirty (30) days following the expiration of
the Term of this Agreement, (B) within ninety (90) days following
the date of termination in the event the Project Agreements are
terminated pursuant to Section 17.1, 17.2 or 17.3 hereof or
(C) within ninety (90) days following the exercise of the Right
of First Refusal described in Section 21 hereof; provided,
however, that in no event shall the transaction be consummated
until the expiration of the waiting period, if any, imposed by
the Hart-Scott-Rodino Antitrust Improvements Act, as amended (if
applicable), and the receipt by the parties of all other
necessary regulatory approvals.  At the termination, EDNC shall
take all action necessary (in the sole discretion of Bayer and
its counsel) to transfer its interest in the Leasehold
Improvements and other assets comprising the EDNC Baytown Plant
and to surrender the Leased Premises free and clear of any and
all liens, encumbrances and liabilities (direct, contingent and
otherwise) other than the Permitted Exceptions (as such term is
defined in the Ground Lease), the Leveraged Lease liabilities
assumed by Bayer (if any) and such other liens, encumbrances and
liabilities imposed by or through Bayer.  The rights set forth in
Section 16, the obligations set forth in this Section 17, and the
indemnification obligations contained in Section 18 and elsewhere
in the Project Agreements shall survive any termination or
expiration of the Project Agreements, and the payment of the
Expiration Termination Fee, the Bayer Default Termination Fee or
the EDNC Default Termination Fee shall be subject to offset by
Bayer for damages otherwise recoverable by Bayer hereunder.

         (C)  In the event that the termination of the
Project Agreements and the payment of the Expiration Termination
Fee, the Bayer Default Termination Fee or the EDNC Default
Termination Fee (as applicable) shall be prohibited or materially
delayed by the operation of the Hart-Scott-Rodino Antitrust
Improvements Act, as amended, the Exon-Florio Act, as amended, or
any other applicable federal, state or local law, EDNC and Bayer
agree to negotiate in good faith appropriate agreements that will
permit EDNC to continue to operate the EDNC Baytown Plant for the
continued production of Nitric Acid for Bayer.  Such agreements
shall include a continuation of term of the Ground Lease and
mutually acceptable terms pertaining to the provision of the
Ammonia, Utilities and Services necessary for the continuing
operation by EDNC of the EDNC Baytown Plant.

         (D)  Upon termination of this Agreement pursuant
to this Section 17 or exercise of the Right of First Refusal
pursuant to Section 21 hereof, the nondefaulting party or parties
shall be entitled to recover from the defaulting party or
parties, in addition to all other sums due and payable by the
defaulting party or parties hereunder, all expenses incurred in
enforcing this Agreement, including without limitation, all
reasonable attorneys' fees and out-of-pocket litigation expenses. 
Termination of this Agreement for any cause whatsoever shall not
interfere with, affect or prevent the collection by the
nondefaulting party or parties of any and all sums of money
accrued hereunder or otherwise due to the nondefaulting party or
parties prior to the date such termination becomes effective. 
Termination of this Agreement for any reason shall not relieve
the defaulting party or parties of any of its or their
unfulfilled obligations under this Agreement, including, without
limitation, its or their indemnification obligations hereunder.

    17.5 Fixed Price Purchase Option

         (A)  Not less than twelve (12) months nor more
than eighteen (18) months prior to the scheduled end of the Lease
Term (as such term is defined in the Operative Agreements), Bayer
may, in its sole and absolute discretion: (i) direct EDNC to
exercise the Fixed Price Purchase Option (provided, however, that
if Bayer elects such option, Bayer shall pay Boatmen's Trust
Company of Texas (or any successor Lessor appointed pursuant to
the Operative Agreements) the Fixed Price Purchase Option Amount,
thereby terminating the Leveraged Lease); (ii) direct EDNC to
exercise the Fixed Price Purchase Option, thereby terminating the
Leveraged Lease, and terminate the Project Agreements (provided,
however, that if Bayer elects such option, Bayer shall pay
Boatmen's Trust Company of Texas (or any successor Lessor
appointed pursuant to the Operative Agreements) the Fixed Price
Purchase Option Amount, thereby terminating the Leveraged Lease,
and shall pay EDNC the Expiration Termination Fee, thereby
terminating the Project Agreements); or (iii) refuse its consent
to the exercise by EDNC of the Fixed Price Purchase Option, in
which case the Fixed Price Purchase Option shall not be payable,
and Bayer may permit the Project Agreements to expire pursuant to
Section 17.3 (provided, however, that if Bayer elects such
option, Bayer shall pay to EDNC the EDNC Expiration Termination
Fee and shall enter into new Project Agreements with Boatmen's
Trust Company of Texas (or any successor Lessor appointed
pursuant to the Operative Agreements) or its designee pursuant to
Section 8 of the Lessor's Consent to Ground Sublease and Non-
Disturbance Agreement.)  In the event that Bayer directs EDNC to
exercise the Fixed Price Purchase Option, then EDNC shall have
the option, and is hereby granted the option, to (i) exercise the
Fixed Price Purchase Option in its own name (or any assignee
approved by Bayer), or (ii) assign the Fixed Price Purchase
Option to Bayer (or its designee) prior to any exercise of the
Fixed Price Purchase Option and Bayer hereby consents to such
assignment.  If the Fixed Price Purchase Option is assigned to
Bayer hereunder, the parties hereto agree that title to the EDNC
Baytown Plant will automatically revert to Bayer.


SECTION 18:  INDEMNIFICATION


    18.1 EDNC Indemnification

         (A)  EDNC shall indemnify and save Bayer and its
Affiliates harmless from and against any and all claims, actions,

without limitation, reasonable attorneys' fees, out-of-pocket
litigation expenses and other costs incurred in connection with
(i) any negligence or misconduct on the part of EDNC or its

bodily injury, loss of life, personal injury or death to persons
or damage to property occurring in or on the EDNC Baytown Plant

negligence or intentional misconduct of the party seeking to be
indemnified, (iii) any breach by EDNC of any Environmental,
Health and Safety Law, any Spill or the remediation, abatement,

or under any of the Project Agreements, provided, however, that
until the occurrence of an EDNC Event of Default:  (a) Bayer's
remedy for EDNC's failure to supply Nitric Acid is expressly
limited to the difference between all costs associated with the
procurement of substitute Nitric Acid and the Variable Costs
Component and (b) Bayer's remedy for off-specification nitric
acid is expressly limited to actual damages.

         (B)  If EDNC's indemnification obligations under
Section 18.1(A) hereof arise or result from EDNC's sole
negligence, EDNC shall (subject to any limitations set forth in
Section 18.1(A) hereof) remain entirely responsible for the
results and consequences of its sole negligence, and if EDNC's
indemnification obligations under Section 18.1(A) hereof arise or
result from joint or concurrent negligence of more than one
party, EDNC shall be responsible (subject to any limitations set
forth in Section 18.1(A) hereof) for only that portion of the
claim, loss, damage, cost or expense caused by the negligence of
EDNC, EDNC's agents or employees, subcontractors retained by EDNC
or agents or employees of such subcontractors.  In all other
cases, all remedies under Section 16 hereof and at law and equity
are available to Bayer.

    18.2 Bayer Indemnification

         (A)  Bayer shall indemnify and save EDNC and its
Affiliates harmless from and against any and all claims, actions,
obligations, suits, damages (whether direct, actual, special,
consequential or otherwise, but excluding lost profits), fines,
penalties, losses, costs, liabilities and expenses, including,
without limitation, reasonable attorneys' fees, out-of-pocket
litigation expenses and other costs incurred in connection with
(i) any negligence or misconduct on the part of Bayer or its
officers, employees, agents, invitees or contractors, (ii) any
bodily injury, loss of life, personal injury or death to persons
or damage to property occurring in or on the Bayer Baytown Plant
(other than the EDNC Baytown Plant or the Construction Laydown

attributable, in whole or in part, to the negligence or
intentional misconduct of the party seeking to be indemnified,

Law or any Spill or the remediation, abatement, containment,
clean-up, disposal or response costs associated with
environmental conditions at the Bayer Baytown Plant or the EDNC
Baytown Plant caused by Bayer, (iv) any failure by Bayer to
observe or comply with any applicable laws or government rules or
regulations or (v) a breach of any other Bayer covenant or
agreement hereunder or any of the Project Agreements, provided,
however, that until the occurrence of a Bayer Event of Default,
EDNC's remedy for Bayer's failure to provide Ammonia, Utilities
or Services is expressly limited to the difference between all
costs associated with the purchase of substitute ammonia,
utilities or services, as the case may be, and the price of
Ammonia, Utilities or Services, as the case may be, under the
Project Agreements.

         (B)  If Bayer's indemnification obligations under
Section 18.2(A) hereof arise or result from Bayer's sole
negligence, Bayer shall (subject to any limitations set forth in
Section 18.2(A) hereof) remain entirely responsible for the
results and consequences of its sole negligence, and if Bayer's
indemnification obligations under Section 18.2(A) hereof arise or
result from joint or concurrent negligence of more than one
party, Bayer shall be responsible (subject to any limitations set
forth in Section 18.2(A) hereof) for that portion of the claim,
loss, damage, cost or expense caused by the negligence of Bayer,
Bayer's agents or employees, subcontractors retained by Bayer or
agents or employees of such subcontractors.  In all other cases,
all remedies under Section 16 hereof and at law and equity are
available to EDNC.

    18.3 Notice of Proceedings - The indemnitee shall give
the indemnitor notice of any suit, proceeding or action (whether
pending or threatened) commenced by any party which could give
rise to damages under this Section 18.  Such notice shall be
given within thirty (30) days of indemnitee's discovery or
receipt of such matter (but the failure to notify within such
time period shall not rescind the indemnitor's duty to indemnify
but shall only reduce the amount of the indemnification amount to
the extent that the indemnifying party is damaged by such delay). 
The indemnitor shall then have the option, at its own cost and
expense, to participate in or assume control of such proceedings
by retaining counsel reasonably acceptable to the indemnitee.  If
the indemnitor does not make its election within thirty (30) days
of its receipt of the indemnitee's notice, the indemnitee may
proceed with the defense of the matter and indemnitor shall be
bound by the result.

    18.4 Insurance - Notwithstanding anything contained in
this Section 18 to the contrary, it is the intention of the
parties to avail themselves, to the maximum extent possible, of
the proceeds of the insurance policies required to be maintained
pursuant to this Agreement and to the extent the damages or
expenses referenced by this Section 18 are paid by such insurance
policies (including deductibles), this indemnity shall be
inapplicable.


SECTION 19:  INJUNCTIVE RELIEF

occur in the event that any of the material provisions of this
Agreement are not performed in accordance with their specific
terms or are otherwise breached and such performance does not
occur or such breach is not cured within the period set forth
above.  Each of the parties therefore agrees that the other
parties shall be entitled to an injunction or injunctions to

hereof, this being in addition to any other remedy to which they
are entitled at law or in equity.

other party written notice of its intention not to renew the Term
of this Agreement not less than twelve (12) nor more than
eighteen (18) months before the expiration of the Initial Term or
the current Renewal Term, as the case may be.  If Bayer gives

EDNC the Expiration Termination Fee and shall terminate the
Project Agreements pursuant to Section 17 hereof.

shall notify Bayer of Bayer's option and right to pay either the
Expiration Termination Fee or the amount of the third party
offer, whichever is lower, and to terminate the Project
Agreements pursuant to Section 17 hereof (the "Right of First
Refusal").  Bayer shall have a reasonable amount of time, not to
exceed sixty (60) days, from its receipt of the notice of a bona-

event that any of the material provisions of this Section 21 are
not performed in accordance with their specific terms or are
otherwise breached and such performance does not occur or such
breach is not cured within the period set forth above.  Each of
the parties therefore agrees that the other party will be
entitled to an injunction or injunctions to prevent
nonperformance or breach of material provisions of this

parties shall then meet and attempt in good faith to resolve the
subject dispute.  If such attempt is unsuccessful, either party
may proceed to litigate the matter at issue.  Any such
negotiation or series of negotiations shall be maintained as
confidential by the parties and the parties covenant that they
shall not disclose (other than to their respective Affiliates)
either the existence of such proceedings or the content thereof
to any other party without the express written consent of the
opposite party.  Any participation in or initiation of such
discussions shall not be deemed to be an admission of liability
and no statement made or provided in or related to such
negotiations shall be construed as a statement against interest
or otherwise disclosed or used in any proceeding involving the
parties.

to participate in the meeting contemplated by Section 22.2
hereof, the other party shall be entitled to request any court of

reduced to nameplate capacity after Day 6.

** One truck will supply Nitric Acid at 98% assay, and the
balance of the trucks will supply Nitric Acid of 65% assay.

Note 1:   The supply plan for planned outage is subject to
          availability of drivers and transportation equipment
          suitable for Nitric Acid services, which EDNC currently
          believes will be available.  Nitric Acid that cannot be
          delivered due to unavailability of transportation
          equipment shall not be included as Production
          Shortfall.

Note 2:   EDNC will use reasonable efforts to supply Nitric Acid
          hereunder at the lowest cost to Bayer, subject to the
          availability of Nitric Acid at the El Dorado, Arkansas
          plant at the time of the planned outage.

Note 3:   EDNC shall invoice Bayer for all costs incurred in the
          delivery of Nitric Acid hereunder.  The price for
          Nitric Acid shipped from the El Dorado, Arkansas plant
          shall be the then-current price for Nitric Acid to
          Bayer under the Project and Supply Agreement, plus the
          applicable transportation charges.  The price for
          Nitric Acid shipped from third parties shall be the
          price billed to EDNC or El Dorado, whichever is
          applicable, plus the applicable transportation charges. 
          When possible, Nitric Acid shall be supplied on a swap
          basis, whether from El Dorado or a third party.

Note 4:   EDNC will return storage to the fifty percent (50%)
          minimum level by running the Nitric Acid Plant at one
          hundred five percent (105%) of nameplate capacity. 
          Nitric Acid would be supplied from El Dorado or third
          party sources as needed to supplement the incremental
          production above Bayer's usage rate; provided, however,
          that EDNC must be able to return the storage to the
          fifty percent (50%) level within a reasonable period
          after the re-start of the EDNC Baytown Plant.

Note 5:   EDNC will use reasonable efforts to supply ninety-eight
          percent (98%) concentrated nitric acid to blend with
          third party acid to bring the average assay to sixty-
          four percent (64%).  EDNC will invoice Bayer at
          El Dorado's then-current average price for ninety-eight
          percent (98%) concentrated nitric acid sales from
          Arkansas plus transportation charges.

Note 6:   Bayer reserves the right to supply the ninety-eight
          percent (98%) concentrated nitric acid from its own
          facilities rather than from El Dorado's Arkansas plant.

Note 7:   The data in Example 1 above are illustrative only and
          in no way bind EDNC or El Dorado to the schedule of
          shipments shown.

* Back in full production at 105% of nameplate capacity.  Rates
reduced to nameplate capacity after Day 10.

** One truck will supply Nitric Acid at 98% assay.


Note 1:   The parties will meet to determine ways to mitigate the
          effects of any unplanned outage on Bayer or EDNC,
          whether or not such unplanned outage is due to EDNC's
          negligence.  If an unplanned outage is due to the
          negligence of EDNC, Bayer shall have the
          indemnification rights set forth in Section 18.1
          hereof.

Note 2:   The supply plan for unplanned outage is subject to
          availability of drivers and transportation equipment
          suitable for Nitric Acid services, which EDNC currently
          believes will be available.  Nitric Acid that cannot be
          delivered due to unavailability of transportation
          equipment shall not be included as Production
          Shortfall.

Note 3:   EDNC shall invoice Bayer for all costs incurred in the
          delivery of Nitric Acid hereunder.  The price for
          Nitric Acid shipped from El Dorado, Arkansas shall be
          the then-current price for Nitric Acid to Bayer under
          the Project and Supply Agreement, plus the applicable
          transportation charges.  The price for Nitric Acid
          shipped from third parties shall be the price billed to
          EDNC or El Dorado, whichever is applicable, plus the
          applicable transportation charges.  When possible,
          Nitric Acid shall be supplied a swap basis, whether
          from El Dorado or third parties.

Note 4:   EDNC will return storage to the fifty percent (50%)
          minimum level by running the Nitric Acid Plant at one
          hundred five percent (105%) of the nameplate capacity. 
          Nitric Acid would be supplied from El Dorado or from
          other sources as needed to supplement the incremental
          production above Bayer's usage rate beyond day five,
          provided, however, that EDNC must be able to return the
          storage to the fifty percent (50%) level within a
          reasonable period after the re-start of the Plant.

Note 5:   EDNC will use reasonable efforts to supply ninety-eight
          percent (98%) concentrated nitric acid to blend with
          third party acid to bring the average assay to sixty-
          four percent (64%).  EDNC will invoice Bayer at
          El Dorado's then-current average price for ninety-eight
          percent (98%) concentrated nitric acid sales from
          El Dorado, Arkansas plus transportation charges.

Note 6:   Bayer reserves the right to supply the ninety-eight
          percent (98%) concentrated nitric acid from its own
          facilities rather than from El Dorado, Arkansas.

Note 7:   The data in Example 2 herein are illustrative only and
          in no way bind EDNC or El Dorado to the schedule of
          shipments shown.
START-UP SUPPLY PLAN

CONDITIONS:    (a)  Supply plan for 65% Nitric Acid requirements
                    up to 260 tons per day (100% acid basis).

                    assay.  El Dorado Nitric Acid at 65% assay. 
                    One full truck of 98% concentrated Nitric
                    Acid per ten trucks of 61% Nitric Acid.

               (e)  Purchases will be steady and continuous to
                    allow trucks and drive teams to be dedicated
                    to the shipments.

NOTES:

     Note 1:   Subject to condition (e) above, the supply plan
               ensures the availability of drivers and
               transportation equipment suitable for Nitric Acid
               service.

     Note 2:   EDNC will use reasonable efforts to supply Nitric
               Acid hereunder at the lowest cost to Bayer.

     Note 3:   EDNC shall invoice Bayer for all costs incurred in
               the delivery of Nitric Acid hereunder.  The price
               for Nitric Acid shipped from El Dorado's plant in
               El Dorado, Arkansas shall be:  ****

               The price for Nitric Acid shipped from third
               parties shall be the price billed to EDNC plus the
               applicable transportation charges.  To the extent
               possible, Nitric Acid will be supplied to the
               Bayer Baytown Plant on a swap basis from El Dorado
               or third parties. 

     Note 4:   When a load is not shipped, Bayer may be charged a
               "non-user" charge, estimated to be **** per unit,
               to cover out-of-pocket expenses for the
               tractor/trailer/driver unit standing-by idle. 
               These charges would apply seven (7) days per week
               for the sixteen (16) units in service.

     Note 5:   EDNC will supply 98% concentrated nitric acid to
               blend with third party acid to bring the average
               assay to 65%.  EDNC will invoice Bayer for the
               nitric acid against the existing swap agreement
               between Bayer and EDNC, plus transportation
               charges.

               If the exchange balance exceeds 1,500 tons in
               favor of EDNC, EDNC has the option to supply
               additional tons of 98% concentrated nitric acid at
               EDNC's then-current average price for sales from
               Arkansas.

     Note 6:   Bayer reserves the right to supply the 98%
               concentrated nitric acid from its own facilities
               rather than from El Dorado's Arkansas plant.

     Note 7:   This start-up supply plan is intended to be a five
               month supply plan.

     Note 8:   Within fifteen (15) days of the end of each
               calendar month under this start-up supply plan,
               EDNC will invoice Bayer for its actual handling
               and unloading costs for Nitric Acid.
