Items 1 and 2.  BUSINESS AND PROPERTIES.

        Terra Industries Inc., a Maryland corporation ("Terra Industries"),
conducts its ongoing operations in the United States through its wholly owned
subsidiary, Terra International, Inc., a Delaware corporation ("Terra
International"), and in Canada, through Terra International (Canada) Inc.
("Terra Canada"), an Ontario corporation and a wholly owned subsidiary of Terra
International.  The principal corporate office of both Terra Industries and
Terra International is located at Terra Centre, 600 Fourth Street, Sioux City,
Iowa 51102-6000 and their telephone number is 712-277-1340.  Unless otherwise
referred to herein or the context otherwise requires, Terra International and
Terra Canada are together referred to as "Terra International."

        Terra International is a leading producer of fertilizer, and a leading  
marketer of fertilizer and crop protection products.  Terra International also
markets seed and provides various agricultural and other related services both
in support of its product sales and on a stand-alone basis.

                                    

GENERAL

        Terra International, directly in the United States and in Canada, is
engaged in the retail and wholesale marketing and distribution of fertilizers,
crop protection, seed and other crop production products, some of which are
proprietary and marketed under Terra International's own brand names.  Terra
International is also engaged in the production of fertilizer and the
formulation of agricultural chemicals.  Terra International's distribution
network is comprised of approximately:

   o     350 farm service centers in North America; 

   o     58 fertilizer storage facilities; and

   o     770 affiliated dealers serving growers in the 48 contiguous states.

   Terra International's production facilities are comprised of:

   o     3 nitrogen fertilizer plants located in Oklahoma (the "Woodward
         Facility"), Iowa (the "Port Neal Facility") and Ontario (the
         "Courtright Facility"),

   o     1 crop protection chemical formulation plant located in Arkansas (the
         "Blytheville Facility"); and

   o     7 additional liquid chemical formulation facilities.


        Terra International's Canadian operations were acquired, effective
March 31, 1993, as a result of the acquisition by Terra International from ICI
Canada Inc. ("ICI") of ICI's interest in the Agromarts(R) and the Courtright
Facility.  Terra Canada's farm service centers operate under the trademark
"Agromart(R)," two of which are wholly owned by Terra Canada.  The others are
operated by corporations in which Terra Canada owns a 50% interest.


        On December 31, 1993, Terra International acquired from The Upjohn
Company the business and most of the assets of Asgrow Florida Company
("Asgrow"), a leading distributor of fertilizer, crop protection products and
seed to





                                       1
<PAGE>   6
the vegetable, citrus and ornamental markets in Florida.  These retail
locations are initially being operated under the name "Terra Asgrow Florida."

   Terra International is organized and conducts its operations through
two primary business units:  Distribution and Manufactured Fertilizer.

DISTRIBUTION

   Terra International's Distribution business, which employed approximately  
1,775 people as of December 31, 1993, manages a network of farm
service centers and a distribution system for crop protection products,
fertilizer and other  crop production products and services.  Through these
operations, Terra International markets a comprehensive line of crop protection
products  (herbicides, insecticides, fungicides, adjuvants, plant growth
regulators,  defoliants and desiccants), fertilizers (nitrogen, phosphates,
potash and  micronutrients), seed and crop production services to farmers and
dealers  primarily in the midwestern, southern, southwestern and southeastern
regions of the United States, and eastern regions of Canada.  Approximately 60%
of the Distribution business' revenues were attributable to retail sales to
growers in 1993 while approximately 40% were attributable to wholesale sales to
dealers.  Terra International operates the largest independently-owned farm
service center network in North America and is the second largest supplier 
(based on revenue) of crop production inputs.

   In addition to selling products required to grow crops, Terra
International's sales representatives provide services to grower customers 
through Terra International's approximately 350 farm service center locations. 
These services include soil and plant tissue analysis and crop production
program recommendations; custom blending of fertilizers; custom field
application services for fertilizer and crop protection products; and field
inspections for pest control and crop program performance follow-up.

   Terra International markets its products primarily to agricultural
customers, including both dealers and growers.  In connection with its product
sales, the Company provides warehousing and delivery services and makes
available to its dealer customers many of the services and training courses
utilized by company-operated locations in support of the sales programs.

   Terra International also markets its products through its Professional
Products group to non-farm customers, including turf growers, nurseries, golf
courses, parks and athletic facilities.  Terra International offers these
customers herbicides, insecticides, fungicides, fertilizer, adjuvants, plant
growth regulators, seed and agronomic services.  Terra International's
Professional Products personnel generally work through existing farm service
center locations using established delivery systems and product lines.

   Terra International's Distribution operations are organized into the
Northern and Southern Divisions and 13 regions.  Field personnel receive
regular training through Terra University(R), a series of courses designed to
develop skills in agronomy, management, sales, environmental and personal
safety, and field application.  The field salespeople are supported by a
full-service soil and plant tissue analysis laboratory, a staff of agronomists
and a research station where the efficacy of various crop protection products
and the performance of numerous seed varieties are tested.

   Terra International markets several major seed brands and, in its U.S.
marketing area, is the largest independent seed distributor.  Terra
International focuses particular marketing efforts on its proprietary brand of
corn hybrids, soybean and cotton seed varieties, which provide higher margins
and represented approximately 20% of total seed sales in 1993.  Terra
International also sells DEKALB brand seed under a unique marketing and
distribution agreement through Terra International's Corn Belt distribution
network.

   Although most agricultural chemicals marketed by Terra International
are manufactured by unaffiliated suppliers, Terra International also markets
its own Riverside(R) brand agricultural chemicals.  Terra International's
Riverside(R) line includes





                                       2
<PAGE>   7
over 100 products, nine of which were added in 1993.  The Riverside(R)
product line consists of herbicides, insecticides, fungicides, adjuvants, seed
treatments, plant growth regulators, defoliants and desiccants.  Terra
International possesses and processes the registrations required by the United
States Environmental Protection Agency (the "EPA") for its Riverside(R)
pesticide products.  Riverside(R) products represented approximately 16% of
total crop protection product sales in 1993.  The majority of Riverside(R)
products are formulated and packaged in facilities owned by the Company.  The
Riverside(R) line includes several formulations produced exclusively by Terra
International, but does not include proprietary agricultural chemicals. 
Riverside(R) products provide higher gross margins than most products
manufactured by unaffiliated suppliers, but the sale of such products also
involves additional indirect costs, including the cost of maintaining and
disposing of excess inventory and potentially greater liability for product
defects.

        Terra International offers its customers a complete production program,
consisting of fertilizer, seed and chemicals for major field crops.  Terra
International's farm service centers utilize its Ag Analytical Services lab in
Elida, Ohio to analyze nutrient levels of customer soil and plant tissue
samples.  The results of these tests are analyzed by Terra International's
proprietary CropMaster(R) program, which provides specific, localized soil
fertility recommendations for specific crops on a field-by-field basis.  Crop
input recommendations are provided via computer terminals at most Terra
International locations, which are linked to a mainframe computer located at
Terra International's headquarters in Sioux City, Iowa. Recommendations can be
made for substantially all crops grown in Terra International's marketing
geography.  The program also provides "least cost" nutrient blending formula
recommendations, makes seed variety recommendations based on hybrid
characteristics and other factors important to the individual grower, and
maintains crop input records for grower customers.

        For selected dealer customers, Terra International offers a services
package called MarketMasterTM to enhance Terra International's relationship
with these key dealers and increase sales.  The package includes environmental
and safety audits, special training courses, access to Terra International's Ag
Analytical Services lab, use of CropMaster(R) and other services.  There were
approximately 475 MarketMasterTM dealer sites at December 31, 1993, and
additional dealer sites are expected in 1994.

PRODUCT FORMULATIONS

        Terra International's Blytheville Facility formulates dry flowable
("DF") crop protection products and liquid crop protection chemicals in
separate production lines at the same location.  DF formulations are small,
dry, water-dispersible granules that are mixed with water before application. 
Because of their dry form, the granules have several benefits compared with
liquid formulations, including:  easier package disposal, easier cleanup of
accidental spills, absence of toxic solvents, no fumes, less weight, less space
required for storage, and no product loss from freezing temperatures or
settling.  Because of these benefits, Terra International expects more
agricultural chemicals will be offered to growers in DF form in the future. 
The Blytheville Facility is one of 13 known DF plants in the U.S. and
formulates eight DF products and six liquid products.  Approximately 40% of the
plant's volume in 1993 was attributable to Terra International's own
Riverside(R) brand product line.  Terra International has developed several DF
formulations not available from any other producer or formulator.  Terra
International has also developed DF formulations for a number of companies that
contract all or portions of their production at the Blytheville Facility.

        In 1988, Terra International formulated a fungicide for E. I. du Pont
de Nemours and Company ("DuPont") at the Blytheville Facility.  The fungicide
was recalled and claims in excess of $90 million, plus punitive damages, were
filed by third parties alleging damages from product use.  Terra International
originally assumed responsibility for the claims and, through its insurers,
paid nearly $60 million in settlements to growers.  Terra International later
discovered evidence that it was not responsible for the claims and filed a
lawsuit against DuPont in Iowa state court for reimbursement of prior claim
payments to growers.  During the fourth quarter of 1993, Terra International
and DuPont reached a comprehensive settlement pursuant to which DuPont assumed
responsibility for all pending product claims, and all litigation between the
parties was dismissed.  In addition, Terra International has resumed





                                       3
<PAGE>   8
its role as a wholesale and retail distributor of DuPont agricultural products,
a status that was interrupted during the product liability litigation.

MANUFACTURED FERTILIZER

        Terra International's Manufactured Fertilizer business, which employed
521 people as of December 31, 1993, produces, sells and delivers nitrogen
fertilizers and selected animal feed ingredients to wholesale agribusiness
customers and anhydrous ammonia products to industrial customers.  Its
principal customers are large independent dealers, national retail chains,
cooperatives and industrial consumers.  Its competitors are typically large
national fertilizer distributors or producers of nitrogen fertilizers.  Terra
International is North America's fifth largest producer of anhydrous ammonia
(the basic raw material for nitrogen fertilizers) and the fourth largest
nitrogen solutions manufacturer.  In 1993, fertilizer and feed ingredients
manufactured by Terra International accounted for approximately 18% of Terra
International's total sales.

        Terra International's nitrogen fertilizer manufacturing facilities,
consisting of the Woodward Facility, the Port Neal Facility and the Courtright
Facility (together, the "Manufacturing Facilities"), are integrated facilities
for the production of anhydrous ammonia, urea liquor and nitrogen fertilizer
solutions. In addition, the Port Neal and Courtright Facilities produce solid
urea for both the feed and fertilizer markets.

   Each Manufacturing Facility is designed to operate continuously except for
planned biennial shutdowns for maintenance or installation of efficiency
improvements.  The average utilization of the Port Neal, Woodward and
Courtright Facilities over the last three years was approximately 92%, 95%, and
91%, respectively.  Utilization for the Port Neal Facility during 1992 was
adversely affected by an extended shutdown for capital improvements and planned
maintenance, which took longer to complete than originally scheduled.  As a
result of the capital improvements, annual anhydrous ammonia production
capacity increased by approximately 70,000 tons in 1993.

        Approximately 90% of Terra International's fertilizer production is
sold to independent dealers, national retail chains, cooperatives and
industrial consumers.  The remaining ten percent is sold through Terra
International's farm service centers to retail customers.


        During 1993, Terra International began implementation of plans to
co-produce methanol and ammonia at its Woodward Facility.  The total project is
expected to be completed in the first half of 1994 and will enable the Company
to convert a portion of that plant's ammonia production to up to 400 tons per
day of methanol, depending on the relative demand of ammonia and methanol.  The
project cost is estimated to be $15 million.

        The acquisition of the Courtright Facility in the second quarter of
1993 added approximately 450,000 tons of capacity to the Company's production
of anhydrous ammonia, 130,000 tons of urea liquor capacity, 140,000 tons of UAN
capacity and 115,000 tons of ammonium nitrate capacity.  The Courtright
Facility's urea liquor and granulation capacity are expected to increase as a
result of a plant upgrade project, announced in February 1994.  The project is
expected to be completed in 1995 and will enable Terra Canada to replace 65,000
tons of annual industrial ammonia sales with higher value urea and nitrogen
solution sales.  The project cost is estimated to be approximately $20 million
and is expected to be funded through lease financing.

CREDIT

        A substantial portion of Terra International's sales to its grower and
dealer customers is made on credit terms customary in the industry.  During the
third quarter of 1992, Terra International established a grower financing
program to provide crop input financing to certain grower customers for all
operating requirements on extended payment terms.  In 1993 Terra International
provided approximately $25 million in financing to grower customers under this
program and expects to finance about $50 million in 1994.

SUPPLY

        Reliable sources for supply of crop inputs at competitive prices are
critical to Terra International's Distribution business.  Terra International
purchases products from various chemical and fertilizer suppliers at prevailing
market prices.  Terra International has entered into purchase agreements with
basic chemical and fertilizer manufacturers to help ensure an adequate supply
of products for its grower and dealer customers through 1994. Terra
International also purchases various chemicals and catalysts used in
manufacturing and formulation. Availability of these materials is currently
considered adequate to meet production needs.

        The principal raw material used by Terra International in its nitrogen
fertilizer manufacturing operations at its Manufacturing Facilities is natural
gas. Natural gas costs comprised approximately 50% of the total costs and
expenses associated with Terra International's Manufactured Fertilizer
operations during 1993.

        Terra International currently purchases natural gas from various
suppliers, principally under 12-month gas supply contracts with a combination
of fixed and market price terms, and engages in the use of other forward
pricing mechanisms to protect against significant unexpected increases in the
price of natural gas.  Terra International has minimized the risk of
interruption or curtailment of its natural gas supply during the heating season
of 1993-1994 by securing firm contracts for the majority of the natural gas 
requirements for its Manufacturing Facilities.  Approximately 40% of Terra 
International's 1994 natural gas requirements have been set by forward
pricing mechanisms.

TRANSPORTATION

        Terra International uses several modes of transportation to receive and
distribute products to customers and its own locations, including railroad and
tank cars, common carrier trucks, barges, common carrier pipelines and
company-owned or leased vehicles.  During 1993, Terra International operated 35
liquid, 21 dry and two anhydrous ammonia fertilizer terminal storage facilities
strategically located in 18 states and Ontario to help ensure efficient
movement and seasonal product availability.  Terra International also has
varying amounts of warehouse space at each of its farm service center
locations.

        Through Terra Express, Inc. and Terra Express of Oklahoma, Inc., wholly
owned truck transportation subsidiaries of Terra International (together,
"Terra Express"), Terra International provides transportation services to its
own facilities and customers as a contract carrier.  Terra Express utilizes
approximately 90 owner-operated units and twenty company-owned units to deliver
fertilizer, crop protection products, seed, feed ingredients and other products
for its customers and Terra International's own locations.  At its
Manufacturing Facilities, its Blytheville Facility and liquid fertilizer
storage locations, Terra International utilizes railcars as the major method of
transportation.  All of Terra International's approximately 1,100 railcars are
leased.

        Purchased gas is transported to the Port Neal Facility via an
interstate pipeline operating as an open access natural gas transporter.  Under
a Federal Energy Regulatory Commission order, Terra International maintains
facilities for direct access to its interstate pipeline shipper, avoiding
additional costs of local utility services.  Terra International transports
purchased natural gas for its Woodward Facility through an intrastate pipeline
that is not an open access carrier; however, Terra International is able to
transport gas supplies from any in-state source connected to the widespread
pipeline system.  The Courtright Facility utilizes local gas storage service
provided by a local utility, and purchased gas is transported from western
Canada through the TransCanada Pipeline under various delivery contracts.

RESEARCH AND DEVELOPMENT

        Terra International operates a 70-acre Agronomy Research Station near
its Port Neal Facility for product and program development and testing, and
routinely conducts product evaluation and testing with growers and
universities.  Terra International also develops DF and other chemical
formulations for its Riverside(R) product line and for basic chemical products
at its product development laboratory located in Blytheville, Arkansas.

CAPITAL EXPENDITURES

        Terra International made capital expenditures of approximately $21.6
million in 1993, of which approximately $6.9 million was used to modify the
Woodward Facility to permit the co-production of methanol (the "Methanol
Project"), and the balance for routine replacements of property, plant and
equipment, and farm service center expansion.  In 1994, Terra International
expects to make capital expenditures of approximately $27 million, consisting
of approximately $8 million to complete the Methanol Project, and the balance
for routine replacements of property, plant and equipment, energy efficiency
improvements to each of the Manufacturing Facilities, and for the expansion of
farm service centers.  Capital expenditures in 1993 exclude capital costs
associated with the acquisition by Terra International of its Canadian
operations from ICI and the acquisition of certain assets from Asgrow, and the
acquisition of additional farm service centers.  Expected 1994 capital
expenditures exclude capital costs associated with significant acquisitions
that may be made in 1994.

PROPERTIES

        Terra Industries and Terra International maintain their headquarters in
Sioux City, Iowa, in an office building owned by Terra Real Estate Corporation,
a wholly owned subsidiary of Terra International.  Terra International owns the
Port Neal and Woodward Facilities, and Terra Canada leases the Courtright
Facility.  The Courtright Facility lease is for a four-year term expiring in
April 1997, and provides Terra Canada with an option to purchase the facility
during the term of the lease and upon expiration thereof. If at the end of the
lease-term Terra Canada elects not to exercise its purchase option, Terra
International must pay to the lessor approximately $40 million (Canadian)
subject to reimbursement based on the proceeds realized on the sale of the
Courtright Facility by the lessor.

        The Blytheville Facility was purchased from the City of Blytheville,
Arkansas at the expiration of the lease term in December 1993, for a nominal
amount.

        Terra International's farm service centers are located on a combination
of owned and leased property.  The leases have varying expiration dates through
2007.  All but two of the Agromarts acquired by Terra Canada during the second
quarter of 1993 are owned by corporations in which Terra Canada owns a 50%
interest, and are owned in fee by such corporations.

        Terra International leases space at 40 liquid and dry fertilizer
storage locations with an average remaining lease life of 12 months from
December 31, 1993.  Each location may have several leases respecting different
products distributed by Terra International.  Terra International owns six
fertilizer solution storage facilities.  In addition, Terra International
maintains certain contractual relationships with terminal facilities respecting
the distribution of dry bulk product, anhydrous ammonia and other manufactured
and distributed products.

EMPLOYEES

        Terra International had approximately 2,390 full-time employees at
December 31, 1993, none of whom were covered by a collective bargaining
agreement.  In addition, Terra International, which annually hires temporary
employees on a seasonal basis, hired approximately 1,500 temporary employees
during its spring selling season in 1993.

SEASONALITY

   The agricultural products business is seasonal, based upon the planting,
growing and harvesting cycles.  As a result, inventories must be accumulated in
the first few months of the calendar year to be available for seasonal sales,
requiring significant storage capacity.  Inventory accumulations are financed
by suppliers or short-term borrowings, which are retired with the proceeds of
the sales of such inventory.  In times of lower demand, Terra International can
reduce purchases, thereby decreasing inventory carrying costs.

COMPETITIVE POSITION

   The market for fertilizer, crop protection products, seed and services
for agriculture is highly competitive.  Nationally, sales attributable to Terra
International's farm service centers accounted for less than 10% of total crop
production products.  However, within the specific market areas served by its
farm service centers, Terra International's share of the market was 
substantially higher.  Terra Internatonal's competitors include cooperatives, 
divisions of diversified agribusiness companies, regional distributors and
independent dealers.  Terra International competes primarily by providing a
comprehensive line of product offerings and by providing value-added services
to growers and dealers.

   Terra International competes with other manufacturers of nitrogen fertilizer
principally on the basis of price, delivery terms and availability of products.

             ENVIRONMENTAL PROTECTION AND OTHER REGULATORY MATTERS

   Terra International's operations are subject to various federal, state
and local environmental protection regulations, including EPA guidelines for
effluent limitations on the waste water discharged by processing units and the
emissions control requirements of the Clean Air Act.  Terra Canada's operations
are subject to various federal and provincial regulations, including the
Canadian Environmental Protection Act administered by Environment Canada, and
the Ontario Environmental Protection Act.  Terra International and Terra Canada
are also involved in the manufacture, handling, transportation and storage of 
materials that are classified as hazardous or toxic by federal, provincial or 
other regulatory agencies.  Precautions are taken to reduce the likelihood of 
accidents involving these materials.

   Terra International has been notified by the EPA that it is a
potentially responsible party ("PRP") under the Comprehensive Environmental
Response, Compensation and Liability Act of 1980 ("CERCLA") in the Matter of
Valley Chemical Site, Greenville, Mississippi.  Other companies have been named
PRPs. Under CERCLA, all PRPs may be held jointly and severally liable for the
costs of investigation and remediation of an environmentally damaged site.  The
EPA has requested that the PRPs remove and dispose of contaminated soils and
other materials at the site but has not at this time required the PRPs to
develop and implement a permanent remediation plan.  Terra International leased
a portion of this site for part of 1986 and 1987, and information obtained by
Terra International indicates the soil contamination occurred prior to the
commencement of such lease. Current estimates of the cost to remove and dispose
of the contaminated materials and the portion, if any, of which Terra
International may be liable are not deemed by management to be material.

   Terra International has also been designated as PRPs under CERCLA or
its analogues under similar state and other legislation and regulations in
connection with its respective ownership of other sites.  After consideration
of such factors as the number and levels of financial responsibility of other
PRPs, the existence of contractual indemnities, the availability of defenses
and the speculative nature of the costs involved, Terra International's
management believes that its liability with respect to these matters will not
be material.

   Certain state regulatory agencies have enacted requirements to provide
secondary containment for bulk agricultural chemical storage facilities present
at Terra International's farm service centers.  The remaining states are
expected to adopt similar requirements pursuant to federal mandate.  Terra
International has commenced





                                       7
<PAGE>   12
construction of these facilities at its farm service centers and estimates that
the future cost of complying with these regulations will be approximately $5
million.

        Terra International endeavors to comply in all material respects with
applicable environmental, safety and health regulations.  Terra International
does not expect its continued operation in compliance with such regulations to
have a material adverse effect on its earnings or competitive position. 

                            DISCONTINUED OPERATIONS

        During 1993 Terra Industries disposed of its leasing and substantially
all of its construction materials businesses for approximately $24.4 million,
and substantially completed the liquidation of its remaining non-agribusiness
properties.  A discussion of each of Terra Industries' remaining discontinued
businesses follows.

CONSTRUCTION MATERIALS

        In September 1993 Terra Industries sold its interest in LTM,
Incorporated, Rogue Aggregates, Inc. and W.B.R., Inc., which did business under
the name "Concrete, Inc.", for approximately $18.5 million.  Terra Industries'
remaining construction materials business, El Rancho Rock & Sand, Inc. ("El
Rancho") is currently being liquidated and reclaimed as required under its
reclamation plan with San Joaquin County, California.  Terra Industries'
management does not expect the net proceeds, if any, from the liquidation of El
Rancho to be material.

METALS MINING

        Beryllium.  During the third quarter of 1993, Terra Industries acquired
the remaining 50% interest in Alloy Research, Inc.  ("ARI") not already owned
by Terra Industries.  ARI, directly and indirectly, through its wholly owned
subsidiary Specialloy, Inc.  ("Specialloy"), produces metal alloys, including
beryllium copper alloys.  The original 50% interest in ARI was acquired
by Terra Industries in 1990.  Terra Industries is currently attempting to sell
its interest in ARI and Specialloy.

        Gold.  Subsidiaries of Terra Industries and Minorco (U.S.A.) Inc., a
majority shareholder of Terra Industries, are partners of Western Gold
Exploration and Mining Company, Limited Partnership ("WestGold"), a limited
partnership.  In 1990, WestGold commenced the liquidation of its operations,
which is now substantially complete.  Terra Industries' management does not
expect the net proceeds, if any, from the liquidation of WestGold to be
material.

ITEM 3.     LEGAL PROCEEDINGS.

   Various legal proceedings are pending against Terra Industries and its
subsidiaries.  Management of Terra Industries considers that the aggregate
liability, if any, resulting from these proceedings will not be material to
Terra Industries.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

   No items were submitted to a vote of security holders of Terra Industries
during the fourth quarter of the 1993 fiscal year.

       3.    Other Financial Statements

                 Individual financial statements of Terra Industries'
                 subsidiaries are omitted because all such subsidiaries are
                 included in the consolidated financial statements being filed.
                 Individual financial statements of 50% or less owned persons
                 accounted for on the equity method have been omitted because
                 such 50% or less owned persons considered in the aggregate, as
                 a single subsidiary, would not constitute a significant
                 subsidiary.

                       REPORT OF INDEPENDENT ACCOUNTANTS



To the Board of Directors
 and Stockholders of
 Terra Industries Inc.



In our opinion, the consolidated financial statements listed in the index under
Item 14(a)(1) and (2) on page 11 of the 1993 Annual Report on Form 10-K present
fairly, in all material respects, the results of operations, cash flows and
changes in stockholders' equity of Terra Industries Inc. and its subsidiaries
for the year ended December 31, 1991, in conformity with generally accepted
accounting principles.  These financial statements are the responsibility of
the Company's management; our responsibility is to express an opinion on these
financial statements based on our audit.  We conducted our audit of these
statements in accordance with generally accepted auditing standards which
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement.  An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation.  We believe that our audit provides a
reasonable basis for the opinion expressed above.  We have not audited the
consolidated financial statements of Terra Industries Inc. for any period
subsequent to December 31,1991.

          SCHEDULE III - CONDENSED FINANCIAL INFORMATION OF REGISTRANT


                  NOTES TO THE CONDENSED FINANCIAL STATEMENTS

1.  BASIS OF PRESENTATION

The Condensed Financial Statements include the Registrant only and reflect the
equity method of accounting for its wholly owned subsidiary, Terra
International, Inc. (International).  Equity in International's 1992 earnings
includes the deduction of $5.7 million for the cumulative effect of accounting
changes to recognize the prior service cost of providing post-retirement
medical benefits to International's employee's.

Equity in the financial results of the base metals, coal, leasing and other
discontinued businesses have been included in discontinued operations.

2.  LONG-TERM DEBT

Long-term debt at December 31, 1993 and 1992 consists of 8.5% Convertible
Subordinated Debentures (Debentures) of $72,057,000 that is due 2012.  Sinking
fund payments of $5,175,000 per year begin in 1998.  The fair value, based upon
redemption provisions, at December 31, 1993 is $74.4 million and at December
31, 1992 was $75.3 million.

The Debentures are convertible into Common Shares any time prior to maturity,
unless previously redeemed, at a conversion price of $8.083 per share.  The
Debentures are subject to redemption, upon not less than 20 days notice by
mail, at any time, as a whole or in part, at the election of the Registrant.
The redemption price, expressed as a percent of the principal amount of the
Debentures to be redeemed, is 103.40% until May 31, 1994, 102.55% until May 31,
1995 and decreasing yearly thereafter to 100% at June 1, 1997.

3.  COMMITMENTS AND CONTINGENCIES

The Registrant is committed to a non-cancelable office lease expiring in 1998.
Total minimum rental payments, are:  1994, $3.1 million; 1995, $3.1 million;
1996, $3.2 million; 1997, $3.3 million and 1998, $1.7 million.  These amounts
are not reduced by sublease rentals, which in 1993 were $2.0 million.

The Registrant is contingently liable for retiree medical benefits of employees
of coal mining operations sold on January 12, 1993.  Under the purchase
agreement, the purchaser agreed to indemnify the Registrant against its
obligations under certain employee benefit plans.  Due to the Coal Industry
Retiree Health Benefit Act of 1992, certain retiree medical benefits of union
coal miners have become statutorily mandated, and all companies owning 50
percent or more of any company liable for such benefits as of certain specified
dates becomes liable for such benefits if the company directly liable is unable
to pay them.  As a result, if the purchaser becomes unable to pay its retiree
medical obligations assumed pursuant to the sale, the Registrant may have to
pay such amount.  The Registrant has estimated that the present value of
liabilities for which it retains contingent responsibility approximates $12
million at December 31, 1993.  In the event the Registrant would be required to
assume this liability, mineral reserves associated with the sold coal
subsidiary would revert to the Registrant.

The Registrant had letters of credit outstanding totaling $13.0 million at
December 31, 1993 and $14.1 million at December 31, 1992, guaranteeing various
insurance and financing activities.  Short-term investments of $13.0 million at
December 31, 1993 and 1992 are restricted to collateralize certain of the
letters of credit.

4.  INCOME TAXES

The Registrant files a consolidated U.S. federal tax return.  The principal
operating subsidiaries provide for federal  income taxes according to tax
sharing agreements which allocate the benefits of operating losses and
differences between financial reporting and income tax basis results to the
Registrant.

"Execution Date") among TERRA INTERNATIONAL, INC., a Delaware corporation (the
"Borrower"), the Lenders listed on the signature page hereof, and CITICORP USA,
INC., as agent for the Lenders (the "Agent").

                 PRELIMINARY STATEMENTS:

                 (1)  The Borrower, the Lenders and the Agent are parties to a
U.S. $130,000,000 Revolving Credit Agreement dated as of November 24, 1992 (the

                 (2)  Terra International (Canada) Inc., a wholly-owned
Canadian subsidiary of the Borrower ("Terra Canada") has entered, or will
enter, into a lease agreement (as amended from time to time in accordance with
the terms thereof, the "Canada Lease") pursuant to which Terra Canada will
lease an ammonia plant located in the province of Ontario, Canada (the
"Plant").  The Canada Lease is structured to be, and it is the intention of the
Borrower that the Canada Lease will constitute, an operating lease and not a
financing lease under both U.S. and Canadian generally accepted accounting
principles.

                 (3)  The Borrower has guaranteed, or will guaranty, certain
payment obligations of Terra Canada under the terms of the Canada Lease (as the
same may be amended from time to time in accordance with the terms thereof, the
"Canada Lease Guarantee").

                 (4)  Terra Canada intends to enter into an unsecured revolving
credit agreement with one or more banks (together with their respective
successors and assigns, the "Revolver Banks") for a maximum aggregate principal
amount of up to a maximum of C$40,000,000 (as the same may be amended from time
to time in accordance with the terms thereof, the "Terra Canada Revolving
Credit Agreement").

                 (5)  The Borrower has guaranteed, or will guaranty, all of the
payment obligations of Terra Canada under the Terra Canada Revolving Credit
Agreement pursuant to a guarantee agreement (as amended from time to time in
accordance with the terms thereof, the "Canada Revolver Guarantee") between the
Borrower and the Revolver Banks.

                 (6)  After the completion of the transactions contemplated by
an asset and share purchase agreement between ICI Canada Inc. ("ICI"), the
Borrower and Terra Canada (the "Purchase Agreement"), Terra Canada will own two

         Canada Documents, for the authorizations, approvals, actions, notices
         and filings listed on Schedule VI hereto, all of which will have been
         duly obtained, taken, given or made and be in full force and effect
         prior to the execution, delivery or performance by the Borrower or
         Terra Canada, as the case may be, of the relevant Canada Document.

                 (e)  This Amendment is the legal, valid and binding obligation
         of the Borrower enforceable against the Borrower in accordance with
         its terms except to the extent that enforcement thereof may be limited
         by bankruptcy, insolvency, reorganization, moratorium or other similar
         laws affecting the enforcement of creditors' rights generally.

                 (f)  Each Canada Document to which Terra Canada is or will be
         a party is, or when delivered will be, legal, valid and binding
         obligations of Terra Canada enforceable against Terra Canada in
         accordance with their respective terms except to the extent that
         enforcement thereof may be limited by bankruptcy, insolvency,
         reorganization, moratorium or other similar laws affecting the
         enforcement of creditors' rights generally.

                 (g)  Subject to any adjustment, pursuant to Article II of the
         Purchase Agreement, to the working capital and the aggregate
         shareholders' equity of the Agromart Corporations on the Closing Date,
         which adjustment will, in accordance with Article II of the Purchase
         Agreement, be made within time frame outlined in the Purchase
         Agreement and be based upon an audit of such items as outlined in the
         Purchase Agreement, the consolidated pro forma balance sheet of the
         Borrower and its Subsidiaries as at February 28, 1993 taking into
         account the transactions contemplated by the Canada Documents,
         certified by a principal financial officer of the Borrower, copies of
         which have been furnished to each Lender, fairly present the
         consolidated pro forma financial condition of the Borrower and its
         Subsidiaries in all material respects as at such date, giving effect
         to the transactions contemplated by the Canada Documents and this
         Amendment, all in accordance with GAAP.

                 (h)  The pro forma balance sheet of the Borrower and its
         Subsidiaries referred to in subsection (g) above were prepared in good
         faith on the basis of certain representations and warranties of ICI in
         the Purchase Agreement as to the book value

         of the Agromart Inventory owned by the Agromart Corporations on the
         Closing Date; in the course of the Borrower's due diligence in
         connection with the negotiation of the Purchase Agreement, no facts
         came to the attention of the Borrower which would cause the Borrower
         to believe that such representations and warranties are materially
         incorrect.

                 (i)  There is no pending or, to the best of our knowledge,
         threatened action or proceeding affecting the Borrower or any of its
         Subsidiaries or Terra Canada before any court, governmental agency or
         arbitrator that purports to affect the legality, validity or
         enforceability of any Canada Document or this Amendment.

                 (j)  Except for the authorizations, approvals, actions,
         notices and filings listed on Schedule VI hereto (all of which will
         have been duly obtained, taken, given or made and will be in full
         force and effect prior to the execution, delivery or performance by
         the Borrower or Terra Canada, as the case may be, of the relevant
         Canada Document), the Borrower and each of its Subsidiaries have each
         obtained all permits, licenses and other authorizations which are
         required under all U.S. and Canadian laws in order to enter and
         perform their respective obligations under the Canada Documents.

                 (k)  No information, exhibit or report furnished to the Agent
         by or on behalf of the Borrower or the Parent in connection with this
         Amendment contained any material misstatement of fact or omitted to
         state a material fact or any fact necessary to make the statements
         contained therein not misleading.

                 (l)  The Seller is not an Affiliate of the Borrower or the
         Parent.

                 (m)  Terra Canada is a wholly-owned subsidiary of the Borrower
         and has been designated as a Restricted Subsidiary pursuant to Section
         5.02(j) of the Agreement.

                 (n)  Set forth on Schedule IV on or after the date hereto is a
         complete and accurate list of all of the Agromart Corporations,
         showing as of the Closing Date (as to each such Agromart Corporation)
         the percentage of the outstanding shares of each class of capital
         stock of such Agromart Corporation to be owned or prepared to be
         acquired (directly or indirectly) by the Borrower on the Closing Date.

                 (o)  Set forth on Schedule V hereto is a complete and accurate
         list of all of the Agromart Credit Agreements, showing as of the
         Closing Date (as to each such Agromart Corporation) the maximum
         principal amount (in Canadian dollars) that can be made available to
         such Agromart Corporation under such Agromart Credit Agreement.

                 SECTION 3.  Conditions Precedent.  The effectiveness of this
Amendment is subject to the conditions precedent that:

                 (a)  The Agent shall have received on or before the Amendment

attributed to them in the Agreement).

        (2)  The Borrower, the Lenders and the Agent have agreed to amend the
Agreement as set forth below.

        NOW, THEREFORE, the parties agree as follows:

        SECTION 1.  Amendments to Agreement.  The Agreement shall be amended as
follows, such amendments to be effective on the date on which the conditions
precedent set forth in Section 3.02 of the Agreement and Section 3 hereof have

        deleting the definitions "Debt", "Long-Term Leverage Ratio" and
        "Short-Term Debt" and adding the following definitions thereto in the
        proper alphabetical order:

        "'Debt' of any Person or entity means, without duplication,

maturing one year or less after the date of creation, Debt which is renewable
or extendible, at the option of the creditor, to a date more than one year from
such date or arises under a revolving credit or similar agreement which
obligates the lender or lenders to extend credit during a period of more than
one year from such date (but not including the current portion of Debt maturing
more than one year after the date of creation).  Without limiting the
generality of the foregoing, "Short-Term Debt" of a Person shall not include
Debt of such Person owing to suppliers of goods or services arising in the
ordinary course of business and not past due."

                 (b)  Section 1.01 of the Agreement is further amended by

        "Priority Debt" the figure $40,000,000" and inserting in lieu thereof
        the figure "$60,000,000".

                 (c)  Section 2.05(b) of the Agreement is amended by deleting
        the phrase (commencing on the sixth line of said Section) "other than
        Short-Term Debt of the Borrower arising under (A) an Agromart Comfort
        Letter, (B) the Canada Lease Guarantee or (C) the Canada Revolver
        Guarantee" and inserting in lieu thereof the following phrase:

                                "other than Short-Term Debt of the Borrower
                 arising under (A) the Canada Lease Guarantee or (B) the Canada
                 Revolver Guarantee".

                 (d)  Section 5.01(j) of the Agreement is amended by inserting

        "Borrower."

                 (e)  Section 5.01(l) of the Agreement is amended by deleting
        the figure $125,000,000" on the




                                      2

        third line of said Section and inserting in lieu thereof

                      (i)  at all times from the date of this Second 
                Amendment through June 29, 1995 of not greater than 0.60:1.0;

                outstanding."

                 (i)  Section 5.02(h) of the Agreement is amended by deleting

         inserting the following phrase on the twenty-eighth line of said
         Section after the words "this Agreement":

                        "; provided, however, that if Borrower makes any

                        amount of dividends Borrower may declare or pay
                        hereunder shall be reduced by 100% of the amount of

         creditors' rights generally.

                 (d)  There is no pending or, to the best of Borrower's
         knowledge, threatened action or proceeding affecting the Borrower or
         any of its Subsidiaries before any court, governmental agency or

                          would constitute an Event of Default but for the
                          requirement that notice be given or time elapse or
                          both;

                    (iv)  A favorable opinion of George H. Valentine, Esq.,

                 furnished pursuant to the preceding provision of this Section
                 3 to the extent necessary to enable them to express the

                            DEFERRAL OF COMPENSATION


                4.01    Salary Deferral.  Each Participant in the Plan may have
          a percentage of Salary (determined without regard to any
          contributions to the Qualified Plan or tax-deferred deposits under
          this Plan) deferred in accordance with the terms and conditions of
          this Plan.  The percentage of Salary deferred cannot exceed 10% of
          the Participant's Salary offset by amounts deferred into the
          Qualified Plan.

                4.02    Bonus Deferral.  Each Participant may defer up to 10%
          of any cash bonuses paid by the Company so long as such deferral is
          in accordance with the terms and conditions of this Plan.

                4.03    Deferral Agreement.  An eligible Executive desiring to
          participate in the Plan must submit a written Deferral Agreement to
          the Administrator on or before the applicable Election Date.  Valid
          Deferral Agreements filed by the applicable Election Date as provided
          in Section 2.10 (a) or (b) shall cause Compensation for services to
          be performed after such date to be deferred in the calendar year in
          which such Agreement is made.  Deferral Agreements entered into under
          the conditions of 2.10(c) shall cause Compensation to be deferred
          beginning January 1 of the next calendar year.

                4.04    No Deferral Without Agreement.  A Participant who has
          not submitted a valid Deferral Agreement to the Administrator before
          the relevant Election Date may not defer any Compensation under this
          Plan for the applicable Plan Year.

                4.05    Duration of Deferral Agreement.  Deferral Agreements
          remain in effect until the year following the year in which they are
          amended or rescinded, but shall be irrevocable as to the amounts
          deferred while they were in effect.

                4.06    Effect of Deferral.  Compensation of any Participant
          that is deferred under the Plan, and benefits payable under the Plan,
          shall be disregarded for purposes of determining the benefits under
          the Terra International, Inc. Employees Retirement Plan, the
          Qualified Plan, and any other employee benefit plan that is
          maintained for the benefit of the Participant.

                      DEFERRAL ACCOUNT AND CREDITING RATE


                5.01    Bookkeeping Account.  Compensation deferred by a
          Participant under a written Deferral Agreement shall be credited in a
          dollar amount to a separate Bookkeeping Account for each Participant.
          Compensation deferred under subsequent written election agreements by
          a Participant shall be added to the Participant's Bookkeeping
          Account.

                5.02    Interest.  Amounts deferred under a written Deferral
          Agreement of a Participant plus an amount equal to the Participant's
          deemed interest and earnings shall be credited to the Bookkeeping
          Account on the same schedule and with the same frequency as interest
          and earnings that are credited to Qualified Plan accounts.

                5.03    Crediting Rate.  The amount in the Participant's
          Bookkeeping Account shall be credited at a rate that reflects the
          gains, losses and income computed as if the Bookkeeping Account were
          invested in certain investment funds available under the Qualified
          Plan, as selected by the Participant in the Deferral Agreement.
          Compensation deferred shall be deemed to be so invested on the date
          the amounts deferred are credited to the Bookkeeping Account.  The
          Company reserves the right to change the basis for determining the
          crediting rate from time to time.

                         possible. The amount of each payment shall equal the
                         Participant's Bookkeeping Account divided by the
                         number of remaining payments (including the payment
                         being determined).

                6.02     Change in Tax Rates.  Notwithstanding the provisions of
          6.01, in the event a Participant's Bookkeeping Account is being paid
          in installment payments and during said pay-out period, Federal
          personal income tax rates for the highest marginal rate are scheduled
          to increase by five or more percentage points, any remaining
          installments to be paid after the effective date of such increase
          shall be paid in one lump sum prior to such effective date.

                6.03     Nonforfeitable Right to Employee Contributions.  The
          Participant shall have a nonforfeitable right to the value of the
          Bookkeeping Account attributable to the Participant's contributions
          plus interest under the terms of this Plan.  Notwithstanding the
          Participant's nonforfeitable right to the value of the Bookkeeping
          Account, the Company has no obligation to fund the account.
          Likewise, any assets which the Company may set aside to help cover
          its financial liabilities are general assets.  Refer to Sections
          11.01 and 11.02 for further explanation.

                6.04     Form of Distribution.  All distributions of a
          Participant's Bookkeeping Account shall be made in cash only.

                6.05     Distribution Before Termination of Service.  In the
          event the Company fails to pay a material amount of any of its
          indebtedness when due and such failure continues after any applicable
          grace period, or permits any material default under any agreement or
          instrument relating to its indebtedness, the Bookkeeping Account
          shall be payable in a lump sum within seven working days.

                             HARDSHIP DISTRIBUTIONS


                7.01    Hardship.  At the request of a Participant before or
          after the Participant's Retirement or Termination of Service, or at
          the request of any of the Participant's beneficiaries after the
          Participant's death, the Committee may, in its sole discretion,
          accelerate and pay all or part of the value of a Participant's
          Bookkeeping Account due under this Plan.  Accelerated distributions
          at the request of the Participant or a Participant's Beneficiaries
          may be allowed only in the event of an unanticipated emergency that
          is caused by an event beyond the Participant's or Beneficiary's
          control and only if disallowance of a distribution would result in a
          severe financial hardship for the Participant or Beneficiary.  An
          accelerated distribution must be limited to only that amount
          necessary to meet the emergency.

                                  BENEFICIARY


                8.01    Beneficiary Designation.  A Participant shall designate
          a Beneficiary to receive benefits under the Plan by completing the
          appropriate space on the Beneficiary Designation Form.  If more than
          one Beneficiary is named, the shares and/or precedence of each
          Beneficiary shall be indicated.  A Participant shall have the right
          to change the Beneficiary by submitting to the Committee a Change of
          Beneficiary form.  However, no Change of Beneficiary shall be
          effective until acknowledged in writing by the Committee.

                8.02    Proper Beneficiary.  If the Company has any doubt as to
          the Proper Beneficiary to receive payments hereunder, the Company
          shall have the right to withhold such payments until the matter is
          finally adjudicated.  However, any payment made by the Company, in
          good faith and in accordance with this Plan, shall fully discharge
          the Company from all further obligations with respect to that
          payment.

                8.03    Minor or Incompetent Beneficiary.  In making any
          payments to or for the benefit of any minor or an incompetent
          Beneficiary, the Committee, in its sole and absolute discretion may
          make a distribution to a legal or natural guardian or other relative
          of a minor or court appointed trustee of such incompetent.  Or, it
          may make a payment to any adult with whom the minor or incompetent
          temporarily or permanently resides.  The receipt by a guardian,
          trustee, relative or other person shall be a complete discharge to
          the Company.  Neither the Committee nor the Company shall have any
          responsibility to see to the proper application of any payments so
          made.

                9.01    Majority Vote.  All resolutions or other actions taken
          by the Committee shall be by vote of a majority of those present at a
          meeting at which a majority of the members are present, or in writing
          by all the members at the time in office if they act without a
          meeting.

                9.02    Finality of Determination.  Subject to the Plan, the
          Committee shall, from time to time, establish rules, forms and
          procedures for the administration of the Plan.  Except as herein
          otherwise expressly provided, the Committee shall have the exclusive
          right to interpret the Plan and to decide any and all matters arising
          thereunder or in connection with the administration of the Plan, and
          it shall endeavor to act, whether by general rules or by particular
          decisions, so as not to discriminate in favor of or against any
          person.  The decisions, actions and records of the Committee shall be
          conclusive and binding upon the Company and all persons having or
          claiming to have any right or interest in or under the Plan.

                9.03    Certificates and Reports.  The members of the Committee
          and the officers and directors of the Company shall be entitled to
          rely on all certificates and reports made by any duly appointed
          accountants, and on all opinions given by any duly appointed legal
          counsel, which legal counsel may be counsel for the Company.

                9.04    Indemnification and Exculpation.  The Company shall
          indemnify and hold harmless each member of the Committee against any
          and all expenses and liabilities arising out of membership on the
          Committee.  Expenses against which a member of the Committee shall be
          indemnified hereunder shall include, without limitation, the amount
          of any settlement or judgment, costs, counsel fees and related
          charges reasonably incurred in connection with a claim asserted, or a
          proceeding brought or settlement thereof.  The foregoing right of
          indemnification shall be in addition to any other rights to which any
          such member of the Committee may be entitled as a matter of law.

                9.05    Expenses.  The expenses of administering the Plan shall
          be borne by the Company.

          is desired, the Participant (or Beneficiary) shall notify the

                         NATURE OF COMPANY'S OBLIGATION


                11.01   Company's Obligation.  The Company's obligations under
          this Plan shall be an unfunded and unsecured promise to pay.  The

          fund its financial obligations under this Plan.

                11.02   Creditor Status.  Any assets which the Company may
          acquire or set aside to help cover its financial liabilities are and
          must remain general assets of the Company subject to the claims of
          its creditors.  Neither the Company nor this Plan gives the
          Participant any beneficial ownership interest in any asset of the
          Company.  All rights of ownership in any such assets are and remain
          in the Company.  Participants shall have the status of general
          unsecured creditors of the Company.

          the Beneficiary, assigns, heirs, executors and administrators.

                12.04   Amendment and Termination.  The Company retains the
          sole and unilateral right to terminate, amend, modify, or supplement
          this Plan, in whole or part, at any time.  This right includes the
          right to make retroactive amendments.  However, no Company action
          under this right shall reduce the Bookkeeping Account of any
          Participant or Beneficiary or reduce benefits that are in payment
          status or shall deprive the Participant without his consent of the
          right to receive the Bookkeeping Account at the time or times
          thereafter elected, with interest.

                12.05   Employment.  This Plan does not provide a contract of
          employment between the Company and the Participant, and the Company
          reserves the right to terminate the Participant's employment for any
          reason, at any time, notwithstanding the existence of this Plan.

          applicable law, no sale, transfer, alienation, assignment, pledge,
          collateralization or attachment of any benefits under this Plan shall

          spouse, or designated Beneficiary shall have any power to
          hypothecate, mortgage, commute, modify, anticipate, or otherwise
          encumber in advance any of the benefits payable hereunder, nor shall
          any of said benefits be subject to garnishment by creditors of any
          Participant or Beneficiary or seizure for the payment of any debts,
          judgments, alimony, maintenance, owed by the Participant or
          Beneficiary, or be transferable by operation of law in the event of
          bankruptcy, insolvency or otherwise.

          payment any federal, state or local taxes required by law to be
          withheld with respect to such payment and such sum as the Company may
          reasonably estimate as necessary to cover any taxes for which the
          Company may be liable and which may be assessed with regard to such
          payment.

                12.08   Applicable Law.  This Plan shall be governed by the
          laws of the state of Iowa except to the extent they are pre-empted by

         WHEREAS, the parties desire Foster to work as a consultant for Terra,
its subsidiaries and affiliates under specified terms and conditions after his

         WHEREAS, the parties now wish to enter into an agreement specifying
the terms of Foster's retirement and the terms under which Foster will act as a
consultant for Terra after his retirement;

         NOW, THEREFORE, the parties hereto mutually agree as follows:

                                   RETIREMENT

         1.   Retirement/Service to Terra in 1993.  Foster shall remain a

transfer date.  Terra shall reimburse Foster for his moving expenses from Sioux
City to Florida.  Foster shall participate in Terra's 1993 Executive Incentive

benefits as a full-time employee through December 31, 1993.

         Foster shall have until December 31, 1996 to exercise all stock

                                   CONSULTING

         2.   Appointment.  Terra hereby retains Foster, as of January 1, 1994,
to provide marketing and consulting services as specified from time to time by
Terra's President and Chief Executive Officer ("CEO").  Foster's appointment
shall terminate on December 31, 1994 unless extended by the parties.

         Unless specifically authorized in writing by Terra's CEO, Foster shall
have no authority to enter into any agreements of any kind on Terra's behalf
and shall not hold himself out as having such authority.  Foster shall
indemnify Terra for any claims, obligations or damages that Terra pays or
becomes obliged to pay arising from any agreements entered into by Foster,
whether written or oral, on behalf, or for the benefit of, Terra, other than
those specifically authorized as set forth in the preceding sentence.  Foster
shall have no authority to spend, or commit to spend, funds on behalf of Terra.
Terra's CEO or CEO's designee will determine and communicate to Foster all work
priorities.  Foster shall report to Terra's CEO or his designee.

         3.   Relationship to Terra.  In undertaking work described in Section
2 hereof, Foster shall not, as of January 1, 1994, be considered for any
purposes an employee of Terra, its subsidiaries, or affiliated corporations.
Foster agrees that he shall not hold himself out as an employee or officer of
Terra, its subsidiaries, or affiliated corporations, to any person or entity.
Foster agrees to accept exclusive liability for payment of any and all payroll
taxes or contributions for unemployment insurance measured by the remuneration
paid by Terra after January 1, 1994 under this Agreement.  The parties agree
that it is their intent, through this Agreement, to establish a relationship of
client-independent contractor, and not that of employer-employee.  The parties
agree to and do hereby waive for themselves, which waiver shall be binding on
their successors, heirs and assigns, the right to make any claim in any form,
that this Agreement establishes an employer-employee relationship.  The parties
agree that by Terra's execution of this Agreement, Terra in no way adopts
liability or responsibility for any action taken by Foster outside the term or
scope of this Agreement.

         4.   Consulting Fee.  Beginning January 1, 1994, Foster agrees to work
on projects as assigned by Terra's CEO or his designee.  In return, Terra
hereby agrees to compensate Foster at a rate of $375 per each half day of work.

         Total hours worked shall be subject to approval in advance by Terra's
CEO or his designee.  Foster shall submit a bill to Terra's CEO by the last day
of each calendar month setting forth all hours worked.  Foster's total
compensation shall be tendered by Terra to Foster on the 15th day of the
following month, by negotiable instrument.

         5.   Travel Approval and Expenses.  All travel or other expenses
undertaken by Foster pursuant to this Agreement must be authorized in advance
by Terra.  Terra agrees to reimburse Foster for all reasonable expenses
incurred by Foster.  Terra's Administration Policy Manual shall govern all
aspects of Foster's undertaking and reimbursement of travel expenses.

         6.   Performance of Services for Other Persons.  During the term of
this agreement, Foster shall not consult or work for other persons, companies
or organizations whose businesses significantly compete with Terra.  For
purposes of this section, companies or organizations that are small relative to
Terra or who do not derive a major portion of their income from the sale


                                      2

or development of agricultural chemicals shall be deemed not to significantly
compete with Terra.  Foster shall advise Terra in writing of the name of each
person or organization for whom he proposes to perform services during the term
of this Agreement.

                              CONSULTING AGREEMENT


         This Consulting Agreement ("Agreement") made and entered into this
30th day of December, 1993, by and between PAUL D.  FOSTER (hereinafter
"Foster"), and TERRA INTERNATIONAL, INC. (hereinafter "Terra"), a Delaware
corporation, having offices at 600 Fourth Street, Sioux City, IA  51101.

         1.      Appointment.  Terra hereby retains Foster, as of January 1,
1994, to provide marketing and consulting services as specified from time to
time by Terra's President and Chief Executive Officer ("CEO").  Foster's
appointment shall terminate on December 31, 1994.

         Unless specifically authorized in writing by Terra's CEO, Foster shall
have no authority to enter into any agreements of any kind on Terra's behalf
and shall not hold himself out as having such authority.  Foster shall
indemnify Terra for any claims, obligations or damages that Terra pays or
becomes obliged to pay arising from any agreements entered into by Foster,
whether written or oral, on behalf, or for the benefit of, Terra, other than
those specifically authorized as set forth in the preceding sentence.  Foster
shall have no authority to spend, or commit to spend, funds on behalf of Terra.
Terra's CEO or CEO's designee will determine and communicate to Foster all work
priorities.  Foster shall report to Terra's CEO or his designee.

         2.      Relationship to Terra.  Foster shall not be considered for any
purposes an employee of Terra, its subsidiaries, or affiliated corporations.
Foster agrees that he shall not hold himself out as an employee or officer of
Terra, its subsidiaries, or affiliated corporations, to any person or entity.
Foster agrees to accept exclusive liability for payment of any and all payroll
taxes or contributions for unemployment insurance measured by the remuneration
paid by Terra after January 1, 1994 under this Agreement.  The parties agree
that it is their intent, through this Agreement, to establish a relationship of
client-independent contractor, and not that of employer-employee.

         3. Consulting Fee.  Beginning January 1, 1994, Foster agrees to
provide up to 50 days of consulting services as assigned by Terra's CEO or his
designee.  In return, shall compensate Foster $50,000 (Fifty Thousand Dollars),
as follows:

                          Terra shall pay Foster $4,166.67 monthly for each
                 1994 calendar month.

                          All days in excess of 50 worked by Foster under this
                 Agreement shall be compensated at the rate of $1,000 (One
                 Thousand Dollars) per day, and shall be reimbursed during
                 December, 1994.

                          Total days worked shall be subject to approval in
                 advance by Terra's CEO or his designee.  Foster shall submit a
                 recap to Terra's CEO by the last day of each quarter setting
                 forth all days worked.

         4.      Travel Approval and Expenses.  All travel or other expenses
undertaken by Foster pursuant to this Agreement must be authorized in advance
by Terra.  Terra agrees to reimburse Foster for all reasonable expenses
incurred by Foster.  Terra's Administrative Policy Manual shall govern all
aspects of Foster's undertaking and reimbursement of travel expenses.

         5.      Performance of Services for Other Persons.  During the term of
this agreement, Foster shall not consult or work for other persons, companies
or organizations whose businesses significantly compete with Terra.  For
purposes of this section, companies or organizations that are small relative to
Terra or who do not derive a major portion of their income from the sale or
development of agricultural chemicals shall be deemed not to significantly
compete with Terra.  Foster shall advise Terra in writing of the name of each
person or organization for whom he proposes to perform services during the term
of this Agreement.

         6.      Term.     This Agreement shall commence on the 1st day of
January, 1994, and shall continue until December 31, 1994.  Foster's
confidentiality agreement set forth in Section 7 is a significant consideration
for Terra entering into this Agreement and shall survive termination of this
Agreement.

         7.      Confidentiality.

                 a.       Foster acknowledges that he has seen, worked with,
and had access to information relating to products owned or developed by Terra
and its subsidiaries, label information, and other information relating to
Terra's business not available to the general public ("Confidential
Information").  The term "Confidential Information" shall include only
information relating specifically to Terra's products or business not available
to the general public and shall not include general, publicly-available
information it being the intent  of the parties that Foster may provide
consulting services to third parties, so long as Foster does not disclose
Confidential Information.

                 b.       Foster agrees he shall not use the Confidential
Information or his knowledge of Confidential Information for any purpose other
than his employment with Terra or services provided to Terra under this
Agreement, nor shall he disclose any Confidential Information to any third
party or use or disclose the Confidential Information or his knowledge thereof
in working for future clients or employers.

                 c.       Foster agrees that at the conclusion of this
Agreement, he shall promptly return all of the Confidential Information which
may be in writing or other concrete form, including any drafts, working
documents or reports containing Confidential Information.

         8.      Other.  This Agreement supersedes the agreement between Foster
and Terra dated May 13, 1993 to the extent, and only to the extent, that the
May 13, 1993 agreement relates to consulting services to be provided by Foster.
However, all provisions of the May 13, 1994 agreement not related to consulting
by Foster shall continue and shall not be affected by this Agreement.

                 In recognition whereof, the parties hereto do affix their
signatures, on this 30th day of December, 1993.

                             TERRA INDUSTRIES, INC.
                           TERRA INTERNATIONAL, INC.

                            INCENTIVE AWARD PROGRAM
                            OFFICER & KEY EXECUTIVE

                                      1994


I.               Purpose of the Plan

                 The purpose of this Incentive Award Program is to motivate
                 officers and key executives of the company toward achievement
                 of planned annual goals and improved results.

II.              Eligibility in the Plan

                 Participation in this Incentive Award Program is limited to
                 officers and key executives of Terra Industries Inc.  and
                 Terra International, Inc., where participation is expected to
                 contribute directly to the company's performance and success
                 in accomplishment of its planned goals.

III.             Special Provisions and Considerations

                 All incentive plan years coincide with the company's fiscal
                 year.  The incentive award for officers and key executives
                 will be based on goals set at the discretion of the President.
                 The importance of the officer and key executive level
                 financial and business planning goals will be reflected in the
                 weighting of each identified individual goal by a percentage
                 relative to one hundred percent (100%).

                 The President will be responsible for the development of the
                 officer and key executive goals and will reach mutual
                 agreement with each officer and key executive on the full set
                 of incentive goals as soon as possible in the fiscal year.
                 Each officer and key executive must execute a goals document
                 that is approved and signed by the President.

IV.              Funding the Officer and Key Executive Incentive Award Program

                 The funding for the officer and key executive incentive award
                 pool is based on the accomplishment of Terra Industries Inc.
                 approved income and return-on-equity objectives which will
                 fund the incentive pool.  The income goal will receive sixty
                 percent (60%) weight and the return-on-equity goal will
                 receive forty percent (40%) weight.


V.               Basis of the Incentive Award

                 The basis of each officer's and key executive's individual
                 incentive award will be base salary as of December 31, 1994.
                 The President has established a set percent of base salary for
                 each officer's and key executive's target incentive award.

                 The maximum incentive award to any officer or key executive
                 will be set at two (2) times that officer's or key executive's
                 targeted award.  There is no incentive payout for goal yield
                 of less than seventy-five percent (75%).  The President, at
                 his discretion, may increase the incentive pool by an
                 additional twenty percent (20%) to award
                 outstanding/exceptional individual contributions to company
                 performance.  The President may also choose to award less than
                 the full amount of the pool.

VI.              Review, Revision and Modification of the Goals

                 Under normal business conditions, the goals will not be
                 altered or revised once established for the year.  Unexpected
                 and unforeseen developments during the course of the incentive
                 award year may prompt re-examination of an officer's or key
                 executive's established goals.  It is the responsibility of
                 each officer and key executive to note the conditions of
                 change which would prompt such a review and take timely
                 action.  Such action would include review with the President
                 for need of revision of an established goal as soon as
                 possible after the detected change.  The change(s) is subject
                 to final approval of the President.

VII.             Payment of Award

                 The incentive award will be paid each officer and key
                 executive in cash as soon as possible after the close of the
                 fiscal year and after approval of the President's
                 recommendations by the Personnel Committee of the Board of
                 Directors.

                 To be eligible for full payment, the officer or key executive
                 must have been in the employ of Terra Industries Inc.  or one
                 (1) of its subsidiaries January 1 of the incentive plan year
                 and must be actively employed by the corporation on the date
                 the incentive award is paid.

VIII.            Special Provision

                 A newly elected officer or key executive will participate in
                 the officer's and key executive's incentive program in
                 proportion to the number of full months worked as an officer
                 or key executive during the incentive program year.

                 An officer or key executive who retires, becomes permanently
                 disabled or dies shall cease to participate in the officer's
                 and key executive's incentive program as of the end of the
                 month coincident with retirement, disability or death.  The
                 proportionate incentive award will be paid as soon as possible
                 after the close of the fiscal year.  While it is the intent of
                 the company to make awards under this plan and to continue the
                 plan from year to year, it reserves the right to amend or
                 terminate the plan entirely at its discretion.

        LEASE dated as of April 8, 1993 (this "Lease"), between W. PATRICK
MORONEY (the "Lessor") not in his individual capacity but solely as Trustee
having an address at 40 West Glen Crescent, Etobicoke, Ontario, M9B 4R1 and
TERRA INTERNATIONAL (CANADA) INC., a corporation governed by the laws of Ontario
(the "Lessee"), having an address at 252 Pall Mall Street, London, Ontario, N6A
5P6.


                             Preliminary Statement

        The Lessor has acquired title to the Property (as defined below) and
wishes to lease the Property to the Lessee and the Lessee wishes to lease the
same from the Lessor.  Capitalized terms used herein and not otherwise defined
herein shall have the respective meanings ascribed thereto in the InterParty
Agreement dated as of the date hereof by and among the Lessor, the Lessee, Terra
International, Inc., a corporation organized under the laws of Delaware,
Montreal Trust Company of Canada, a trust company organized under the laws of
Canada, as Paying Agent and the financial institutions named therein, as the
same may be amended, modified or supplemented from time to time (the "InterParty
Agreement").

        NOW, THEREFORE, the parties do hereby covenant and agree as follows:

        1.  Lease of Property; Title and Condition.  (a)  In consideration of
the rents and covenants herein stipulated to be paid and performed by the Lessee
and upon the terms and conditions herein specified, the Lessor hereby leases to
Lessee the parcel of land, more particularly described on Schedule A hereto,
together with all easements, rights and appurtenances relating thereto (herein
called the "Parcel") and all structures, buildings and other improvements now or
hereafter located thereon and affixed thereto, including, without limitation,
the Facility (collectively, the "Improvements"), and the Lessee hereby leases
from the Lessor the Improvements and the Parcel.  The Improvements and the
Parcel are sometimes herein collectively called the "Property".

        (b)   THE LESSEE SHALL TAKE POSSESSION OF THE PROPERTY ON AN "AS IS"
BASIS. THE LESSOR MAKES NO WARRANTY OR REPRESENTATION, EXPRESS OR IMPLIED, WITH
RESPECT TO THE PROPERTY OR ANY FIXTURE OR OTHER ITEM CONSTITUTING A PORTION
THEREOF, OR THE LOCATION, USE, DESCRIPTION, DESIGN, MERCHANTABILITY, FITNESS FOR
USE FOR ANY PARTICULAR PURPOSE, CONDITION, OR DURABILITY THEREOF OR AS TO THE
QUALITY OF THE MATERIAL OR WORKMANSHIP THEREIN, OR AS TO THE LESSOR'S TITLE
THERETO OR OWNERSHIP THEREOF OR OTHERWISE IT BEING AGREED THAT ALL RISKS
INCIDENT THERETO ARE TO BE BORNE BY THE LESSEE.  IN THE EVENT OF ANY DEFECT OR
DEFICIENCY OF ANY NATURE IN THE
<PAGE>   5
PROPERTY, OR ANY FIXTURE OR OTHER ITEM CONSTITUTING A PORTION THEREOF,
WHETHER PATENT OR LATENT, THE LESSOR SHALL HAVE NO RESPONSIBILITY OR LIABILITY
WITH RESPECT THERETO.  THE PROVISIONS OF THIS SUBPARAGRAPH 1(b) HAVE BEEN
NEGOTIATED BY THE PARTIES HERETO AND ARE INTENDED TO BE A COMPLETE EXCLUSION AND
NEGATION OF ANY AND ALL WARRANTIES, EXPRESS OR IMPLIED, BY THE LESSOR WITH
RESPECT TO THE PROPERTY OR ANY FIXTURE OR OTHER ITEM CONSTITUTING A PORTION
THEREOF, WHETHER ARISING PURSUANT TO ANY LAW NOW OR HEREAFTER IN EFFECT.  LESSEE
ACKNOWLEDGES THE PERMITTED ENCUMBRANCES (AS DEFINED IN THE INTERPARTY AGREEMENT)
AND AGREES TO BE BOUND BY THE SAME.  THE PROPERTY IS LEASED TO THE LESSEE
SUBJECT TO (A) ALL APPLICABLE LEGAL REQUIREMENTS AND ALL INSURANCE REQUIREMENTS
NOW OR HEREAFTER IN EFFECT; AND (B) ALL PERMITTED ENCUMBRANCES.  THE LESSEE HAS
EXAMINED THE PROPERTY AND TITLE THERETO AND HAS FOUND THE SAME SATISFACTORY FOR
ALL PURPOSES OF THIS LEASE.

        2.  Use; Quiet Enjoyment; Hazardous Materials.  (a)  The Lessee shall
use the Property solely as an anhydrous ammonia production and upgrading
facility (and for the production of by-products and co-products related
thereto), storage facilities and related business offices (or any other use
lawfully permitted and to which the Lessor has consented) in a first class and
reputable manner.  The Lessee shall not in any event use or allow the use of the
Property, or any part thereof, for any other purpose without the prior written
consent of the Lessor.  The Lessee covenants that it will cause the Improvements
at all times to be located on the Parcel.

        (b)   Subject to the terms of this Lease (and unless a Default, an Event
of Default or an Unwind Event has occurred and is continuing), the Lessee is
entitled to peaceably and quietly hold and enjoy the Property for the Lessee
without interruption by the Lessor, or any other person lawfully claiming by,
through or under the Lessor; provided, however, that the Lessor and the
Purchasers and their respective successors, assigns, representatives, agents,
employees, consultants and contractors (including, without limitation, the
Environmental Consultant) (the "Lessor Group"), may, at all reasonable times
upon reasonable notice to the Lessee enter upon and examine the Property or any
portion thereof and the Lessee's books and records relating to the Property or
such portion thereof and its operation therefrom and perform such tests and
procedures to conduct an environmental audit on the Property as the Lessor Group
may require except that if the Lessor acting reasonably has reason to believe
that a Default, an Event of Default or an Unwind Event has occurred, any
reasonable entrance, examination and testing may be conducted at any time
without notice.  Any such entrance and examination pursuant to this paragraph
2(b) shall not constitute a breach of the Lessor's covenant for quiet enjoyment.
The Lessor shall use reasonable efforts to cause


                                      2
<PAGE>   6
any member of the Lessor Group to use reasonable efforts when exercising
rights under this subparagraph (b) to avoid, or where unavoidable, to minimize
any interference or disruption of business operations being carried out on the
Property.

        (c)  Lessor, at Lessee's sole cost and expense, shall cooperate or
assist with Lessee's efforts to obtain all services, Permits and contracts
necessary and useful for the lawful operation and maintenance of the Property
for the intended purposes thereof and the Lessor shall execute such documents or
instruments as may be reasonably necessary for such purposes.  Lessee covenants
that it shall at its own cost and expense, obtain and maintain during the Term,
all Permits required in order to permit the lawful occupation and operation of
the Property for the intended purposes hereof.  Lessee further covenants that it
shall at its own cost and expense on behalf of and in the name of the Lessor,
apply for, obtain and maintain all Permits required in order to permit the
lawful ownership of the Property by the Lessor.

        (d)  Any failure by the Lessor or such other Person referred to in
paragraph 2(b) to comply with the foregoing provisions of this paragraph 2 or
any other provision of this Lease shall not give the Lessee any right to cancel
or terminate this Lease, or to abate, reduce or make deduction from or offset
against any Fixed Rent, Additional Rent or other sum payable under this Lease,
and shall not relieve Lessee from its obligation to perform or observe any other
covenant, agreement or obligation hereunder.

        (e)  The Lessee shall, and it shall require and ensure that any and all
employees, contractors, subcontractors, agents, representatives, affiliates,
consultants, permitted assignees and sublessees, occupants and any and all other
Persons, (i) comply with all Environmental Laws applicable to operations on the
Property, and (ii) manufacture, distribute, treat, use, employ, process, emit,
generate, store, handle, transport, dispose of and/or arrange for the disposal
of any and all Hazardous Materials in, on, under or about or, directly or
indirectly, related to or in connection with the Property or any part thereof in
compliance with all applicable Environmental Laws and in a manner consistent
with prudent industry practice and which does not pose a significant risk to
human health and safety (including occupational health and safety) or the
environment.

        3.  Term.  The Property is leased for a term (the "Term") of four (4)
years commencing on April 8, 1993 and ending on April 8, 1997 (the "Expiration
Date"), or such earlier date as this Lease shall be terminated pursuant to any
provision hereof; provided however, this Lease may be extended for the Extended
Term pursuant and subject to paragraph 27(c) hereof or may be extended pursuant
to paragraph 15(b) hereof,

                                       3
<PAGE>   7
in which event the definition of "Term" shall include the Extended Term and 
such extension pursuant to paragraph 15(b).

        4.  Rent.  (a)  During the Term, Lessee shall pay to the Paying Agent on
behalf of the Lessor on each Payment Date Fixed Rent in the amounts determined
in accordance with Schedule B hereto.  All payments of Fixed Rent hereunder
shall be allocated as to .326% to the Parcel and as to 99.674% to the
Improvements, respectively.

        (b)  All amounts that the Lessee is required to pay to the Lessor or the
Paying Agent pursuant to this Lease (other than Fixed Rent), including, but not
limited to, any and all amounts payable upon transfer or purchase of the
Property and every fine, penalty, interest and cost that may be added for
non-payment or late payment thereof, shall constitute "Additional Rent."  Each
of Lessor and the Paying Agent shall give Lessee notice of any Additional Rent
due hereunder promptly after it has knowledge of such Additional Rent, and shall
use reasonable efforts to notify Lessee in advance of the due date and amount of
such Additional Rent; provided that failure to give such prompt notice shall not
relieve the Lessee of its obligation to pay such Additional Rent.  In the event
that the Lessee shall pay Additional Rent in excess of amounts actually due and
payable to the Lessor, the excess shall, at the option of the Lessor, be
forthwith paid to the Lessee or be applied in payment of other amounts owing by
the Lessee or in reduction of future payments due under this Lease.  In the
event that the Lessee shall pay Additional Rent in an amount less than the
actual amount due and payable to the Lessor, the Lessee shall forthwith upon
demand from the Lessor or the Paying Agent pay such deficiency.  The Lessor and
the Lessee agree that all payments of Additional Rent in respect of a period
which extends beyond the Expiration Date or earlier termination of this Lease
shall be prorated.

        (c)  All amounts payable by the Lessee to the Lessor hereunder shall
bear interest at the Default Rate from the due date thereof until paid in full,
both before and after demand, default and judgment, with interest on overdue
interest at the same rate, and such interest shall be payable on demand.

        (d)  All amounts payable by the Lessee hereunder shall be paid in lawful
money of Canada and in immediately available funds by 10:00 A.M.  (Toronto time)
on the date when due, unless any such due date is not a Business Day in which
case payment shall be due and payable on the next succeeding Business Day at the
Paying Agent's Office.

        (e)  The Lessee shall perform all of its obligations under this Lease at
its sole cost and expense and shall pay, when due and without notice or demand
(except as otherwise

                                       4
<PAGE>   8
provided in this Lease), all amounts due hereunder.  The Lessee agrees
to pay, or cause to be paid, on demand (i) all Impositions (subject to Lessee's
rights pursuant to paragraphs 11 and 18) and (ii) all charges, fees, costs and
expenses of the Lessor, the Purchasers, Lessor's counsel, the Paying Agent, the
Paying Agent's counsel, the Appraiser, the Environmental Consultant and Special
Counsel, in connection with the preparation, execution, delivery,
administration, performance, modification and amendment of this Lease and the
other Operative Documents and any other documents to be delivered in connection
herewith or therewith or in connection with or arising out of any refinancing or
refunding thereof, including, without limitation, the fees and expenses of
Trustee's Counsel and Special Counsel for the holders from time to time of the
Instruments with respect hereto or thereto, with respect to advising any of them
as to their respective rights and responsibilities hereunder or thereunder, and
all costs and expenses, if any (including, without limitation, legal fees and
expenses), in connection with the enforcement (whether through negotiations,
legal proceedings or otherwise) of any of the Operative Documents and such other
documents.

        5.  Net Lease; Non-Terminability.  (a)  The Lessee acknowledges and
agrees that it is intended that this Lease shall be a completely carefree and
triple net lease for the Lessor and that the Lessor shall not be responsible
during the Term for any costs, charges, expenses, payments and outlays of any
nature whatsoever arising from or relating to the Property, whether foreseen or
unforeseen and whether or not within the contemplation of the parties at the
commencement of the Term, so as to provide the Lessor an absolutely net rent,
free and clear of all deductions, compensation, abatement or set-off throughout
the Term.  It is intended that the Lessee shall pay all costs, charges,
expenses, payments and outlays of any nature whatsoever arising from or relating
to the Property, whether foreseen or unforeseen, and whether or not within the
contemplation of the parties at the commencement of the Term. Except as
otherwise expressly provided in this Lease, and notwithstanding any present or
future Law to the contrary the Lease shall not terminate, nor shall the Lessee
be entitled to any abatement, reduction, set-off, counterclaim, defense or
deduction with respect to any Fixed Rent, Additional Rent or other sum payable
hereunder.  Except as otherwise expressly provided in this Lease, the
obligations of the Lessee hereunder shall be absolute and unconditional and
shall not be affected by reason of: (i) any damage to or destruction of the
Property or any part thereof by any cause whatsoever (including, without
limitation, by fire, Casualty or act of God or enemy or any other force majeure
event); (ii) any Expropriation, including, without limitation, a temporary
Expropriation of the Property or any part thereof; (iii) any prohibition,
limitation, restriction 


                                       5
<PAGE>   9
or prevention of the Lessee's use, occupancy or enjoyment of the
Property or any part thereof by any Person; (iv) any matter affecting title to
the Property or any part thereof; (v) any eviction of the Lessee from, or loss
of possession by the Lessee of, the Property or any part thereof, by reason of
title paramount or otherwise; (vi) any default by the Lessor hereunder or under
any other Operative Document or agreement; (vii) the invalidity or
unenforceability of any provision hereof or the impossibility or illegality of
performance by the Lessor or the Lessee or both; (viii) any action of any
federal, provincial or local governmental authority; or (ix) any other cause or
occurrence whatsoever, whether similar or dissimilar to the foregoing.  The
parties intend that the obligations of the Lessee hereunder shall continue
unaffected unless such obligations shall have been modified or terminated
pursuant to an express provision of this Lease.

        (b)  The Lessee shall remain obliged under this Lease in accordance with
its terms and shall not take any action to terminate, rescind or avoid this
Lease, notwithstanding any bankruptcy, insolvency, reorganization, liquidation,
dissolution or other proceeding affecting the Lessor or any action with respect
to this Lease which may be taken by any trustee, receiver or liquidator or by
any court. Except as expressly permitted in this Lease, the Lessee waives all
rights to terminate or surrender this Lease, or to any abatement or deferment of
Fixed Rent, Additional Rent or other sums payable hereunder.  The Lessee shall
remain obliged under this Lease in accordance with its terms and the Lessee
hereby waives any and all rights now or hereafter conferred by Law or otherwise
to modify or to avoid strict compliance with its obligations under this Lease. 
All payments made by the Lessee to the Lessor or the Paying Agent hereunder as
required hereby shall be final and the Lessee shall not seek to recover any such
payment or any part thereof for any reason whatsoever, absent manifest error,
subject to any adjustment of Additional Rent permitted by this Lease.

        (c)  Lessee hereby acknowledges that parts of the Property are comprised
of the Easement Lands and are subject to the Easement Agreements.  Lessee
covenants that it shall observe and perform all covenants and obligations on the
part of the Lessor to be observed and performed pursuant to the Easement
Agreements and Lessee shall indemnify and save harmless the Lessor, his
representatives and agents, from and against all claims, demands, actions,
suits, proceedings, fines, liabilities, costs and expenses of any nature or kind
whatsoever caused or arising, directly or indirectly, or related to the
performance or non-performance of the Lessor's obligations under the Easement
Agreements.

        6.  Taxes and Assessments; Compliance with Law; Certain Agreements.  (a)
The Lessee shall pay or cause to be


                                       6
<PAGE>   10
paid, subject to paragraph 18, all Impositions when due and before any
fine, penalty, interest or cost may be added or any default may be claimed or
any termination or foreclosure or forfeiture procedures for nonpayment may be
commenced.  If any Imposition may legally be paid in installments, such
Imposition may be so paid in installments; provided, however, that all such
installments which may be due from time to time shall be paid by the Lessee by,
on or before the Expiration Date or earlier termination of this Lease.

        (b)  The Lessee shall comply with, and cause the Property (and all
assignees and sublessees of any part of the Property) to comply with, all Legal
Requirements.  "Legal Requirements" means (i) all Laws, including, without
limitation, all Environmental Laws, foreseen or unforeseen, ordinary or
extraordinary, or arising from any restriction registered on title to the
property record or otherwise, which now or at any time hereafter may be
applicable to the Lessor, as owner of the Property, the Lessee, as lessee
hereunder, the Property or any part thereof, or any of the adjoining sidewalks
or other property, or the ownership, construction, operation, mortgaging,
occupancy, possession, use, non-use or condition of the Property or any part
thereof; (ii) any other governmental rules, regulations, orders, directives and
determinations now or hereafter enacted, made, issued or promulgated, and
applicable to the Lessor, as owner of the Property, the Lessee, as lessee
hereunder, the Property or any part thereof, or any of the adjoining sidewalks
or other property, or the ownership, construction, operation, mortgaging,
occupancy, possession, use, non-use or condition of the Property or any part
thereof whether or not presently contemplated; and (iii) all agreements,
Permits, covenants, and restrictions applicable to the Property or any part
thereof or the ownership, construction, operation, mortgaging, occupancy,
possession, use, non-use or condition thereof.

        (c)  Lessee shall promptly, but in any case within five (5) Business
Days of the receipt thereof, forward to Lessor and the Paying Agent copies of
any written notices, orders, directives, complaints, claims, demands, or any
other communications received by Lessee relating to violations or alleged
violations of any Environmental Law or potential adverse actions in any way
involving environmental, health, or safety matters affecting the Property or any
part thereof in which the clean-up obligations or corrective action or the
liability under any Environmental Law could exceed $100,000.  Lessee shall
promptly notify Lessor and the Paying Agent when it becomes aware of any spill,
discharge, deposit, emission, leak or any other release of any Hazardous
Material, whether or not such spill, discharge, deposit, emission, leak or other
release occurred prior to, on or after the date hereof, at, in, on, under or
from the Property or any part thereof or at, in, on, under or from any adjacent
property that is required


                                       7
<PAGE>   11
to be reported to any governmental authority or in respect of which the
clean-up obligations or corrective action or the liability under any
Environmental Law could exceed $100,000.  Lessee shall promptly notify Lessor
and the Paying Agent when it becomes aware of any spill, discharge, deposit,
emission, leak or other release of any Hazardous Material, whether or not such
spill, discharge, deposit, emission, leak or other release occurred prior to, on
or after the date hereof at, in, on, under or from any real property adjoining
or in the vicinity of the Property that could impair the value of the Property. 
Irrespective of whether Lessee is to give notice of any of the matters set forth
in this paragraph 6(c), Lessee shall immediately initiate, at its sole cost and
expense, such actions as may be necessary to comply in all respects with all
applicable Environmental Laws and to alleviate any significant risk to human
health or the environment.  Once Lessee commences such actions, Lessee shall
thereafter diligently and expeditiously proceed to comply in a timely manner
with all Environmental Laws and to eliminate any significant risk to human
health or the environment and shall, at the request of the Lessor, the Paying
Agent or any Purchaser, give periodic progress reports on its compliance efforts
and actions.

        (d)   Tax Matters.  (i)  The Lessor and the Lessee hereby agree to
jointly elect under subsection 16.1(1) of the Income Tax Act (Canada), in the
prescribed form and within the prescribed time for the purposes of the Income
Tax Act (Canada) in respect of such part of the Property in respect of which
such an election may be made. For the purpose of such election, the Lessor and
the Lessee hereby agree that the fair market value to be assigned to the items
contained in the various classes of depreciable property subject to the election
is as outlined in the attached Schedule D.  The Lessee and the Lessor covenant
and agree to join in or make such other joint elections under the Income Tax Act
(Canada) as the other may from time to time reasonably require in order to
protect its economic interests under this Lease; provided, however, that the
Lessor or the Lessee may refuse to join in or make any other joint election if
such other election would be to the detriment of its economic interests under
this Lease.

                (ii)  The Lessor is not a non-resident of Canada for the 
        purposes of the Income Tax Act (Canada) and during the Term will be a 
        resident of Canada for purposes of the Income Tax Act (Canada).

                (iii) The Trust is and will remain throughout the Term a
        registrant under Subdivision d of Division V of Part IX of the Excise
        Tax Act (Canada).

        7.  Matters of Title.  (a)  The Lessee shall not create or permit to be
created or exist, and shall promptly


                                       8
<PAGE>   12
remove and discharge, any Lien upon this Lease or the Property or any part
thereof or interest therein, or upon any Fixed Rent, Additional Rent or other
sum payable hereunder, which Lien arises for any reason, including, without
limitation, any and all Liens which arise out of the ownership, use, condition,
occupancy, construction, possession, repair or rebuilding of the Property or
any part thereof or by reason of labor or materials furnished or claimed to
have been furnished to the Lessee or for the Property or any part thereof, but
excluding Permitted Encumbrances.

        (b)   Nothing contained in this Lease shall be considered as
constituting the consent or request of the Lessor, express or implied, to or for
the performance by any contractor, laborer, materialman, or vendor of any labor
or services or for the furnishing of any materials for any construction,
alteration, addition, repair or demolition of or to the Property or any part
thereof.  NOTICE IS HEREBY GIVEN THAT THE LESSOR IS NOT AND SHALL NOT BE LIABLE
FOR ANY LABOR, SERVICES OR MATERIALS FURNISHED OR TO BE FURNISHED TO THE LESSEE,
OR TO ANYONE HOLDING OR POSSESSING THE PROPERTY OR ANY PART THEREOF THROUGH OR
UNDER THE LESSEE, AND THAT NO MECHANIC'S OR OTHER SIMILAR STATUTORY LIENS FOR
ANY LABOR, SERVICES OR MATERIALS SHALL ATTACH TO OR AFFECT THE PROPERTY OR ANY
PART THEREOF.

        (c)  The Lessor shall not create any Lien upon this Lease or the
Property or any part thereof except (i) Permitted Encumbrances, (ii) those Liens
created by this Lease and the Declaration, and (iii) in respect of any action
taken by the Lessor or the holders from time to time of the Instruments in
connection with the enforcement of any rights under any Operative Document.

        (d)  The Lessor may at any time, without the consent of the Lessee,
transfer, sell, assign or otherwise dispose of its interest in the Property or
any part thereof (subject always to this Lease and all rights of the Lessee
hereunder) or its right, title and interest in this Lease provided that, unless
such transfer is made in order to enforce any rights of the Lessor or the
Holders from time to time of the Instruments under any Operative Document or
such transfer is the result of the Lessee's purchase of the Property pursuant to
paragraphs 14 or 27 hereof (or pursuant to the Lessor's rights to sell or
dispose of the Property if the Lessee does not purchase the Property pursuant to
paragraph 27 hereof), such transfer shall be made as part of a transfer of the
Lessor's interest in all of the Operative Documents in accordance with the terms
of the InterParty Agreement and prior to completion of the transfer, the
transferee shall covenant with the Lessee to assume all of the Lessor's
obligations hereunder and under the other Operative Documents, including, but
not limited to, a covenant that (i) the


                                       9
<PAGE>   13
transferee is not a non-resident of Canada for the purposes of the Income Tax
Act (Canada) and during the Term will be a resident of Canada for
the purposes of the Income Tax Act (Canada) and (ii) the Trust is and will
remain throughout the Term a registrant under Subdivision d of
Division V of Part IX of the Excise Tax Act (Canada).

        8.  Certain Zoning Matters.  Lessor agrees that Lessee during the Term
shall have the exclusive right (so long as no Default, Event of Default or
Unwind Event has occurred and is continuing) to secure subdivision approvals,
site plan approvals, annexation or de-annexation approvals, zoning amendments or
minor variances, and Permits necessary or desirable for the development, use,
operation, maintenance or condition of the Property or any part thereof;
provided that the fair market value or use of the Property is not lessened
thereby.  Lessor agrees to execute such documents and take all other actions as
shall be reasonably necessary, and otherwise cooperate with Lessee, in
connection with the matters described above, including without limitation, such
conveyances, consents, releases and other assurances as may be reasonably
required by the Lessee to transfer to any governmental agency or authority, or
any utility, such part or parts of the Property, or any easements in respect
thereof as may be required for municipal, governmental or public utility
purposes, such as roads, road widenings, walkways, one-foot reserves, utility
easements and other like purposes; provided that the fair market value or use of
the Property is not lessened thereby; provided, however, that all costs and
expenses incurred by the Lessor in connection therewith shall be borne by Lessee
and that Lessor shall not be required to execute any documents which would, in
the opinion of the Lessor, adversely affect the value or use of the Property or
otherwise adversely affect the transactions contemplated by the Operative
Documents or the interests of the Lessor or the holders from time to time of the
Instruments.

        9.  Maintenance and Repair.  (a)  The Lessee, at its own expense, will
manage and maintain the Property in good working order and in good mechanical
condition and repair, in accordance with prudent industry practice and in a
manner consistent with that of other similar properties owned or operated by it
or its Affiliates, and will take all action, and will make all changes and
repairs, structural and nonstructural, foreseen and unforeseen, ordinary and
extraordinary, capital and non-capital, which may be required to maintain the
Property as aforesaid, or which may be required pursuant to any Legal
Requirement or Insurance Requirement at any time in effect.  Lessee shall, in
accordance with prudent industry practice, repair or replace each item
comprising part of the Improvements that shall have become worn out, obsolete,
damaged or inoperative in whole or in part; provided, however, that the fair
market value of the


                                      10
<PAGE>   14
Property shall not be lessened thereby and that such replacements shall be of a
type currently used in the industry for the same purpose and
having a useful life at least as long as that of the Improvements repaired or
replaced (prior to obsolescence, loss or damage and the like).
All repairs, replacements and rebuilding by the Lessee hereunder shall
immediately become and shall remain part of the Property of the Lessor,
subject to this Lease.  The Lessor shall not be required to, and Lessee hereby
waives any right to require the Lessor to, manage, maintain,
replace, repair or rebuild the Property or any part thereof and Lessor shall
not be responsible for paying the cost of such management,
maintenance, replacements, repairs or rebuilding and the Lessee waives any and
all rights it may now or hereafter have to make any repairs or
replacements at the expense of the Lessor pursuant to any Legal Requirement or
Insurance Requirement, at any time in effect or otherwise.

        (b)  In the event that all or any part of the Improvements shall
encroach upon any property or right-of-way adjoining or adjacent to the Parcel
or any part thereof, or shall violate any agreements or conditions affecting the
Property or any part thereof, or shall obstruct any easement or right-of-way to
which the Property or any part thereof may be subject, then the Lessee shall, at
its sole cost and expense, either (i) contest such matter pursuant to paragraph
18 hereof, (ii) obtain valid and effective Permits for or consents to such
encroachments and/or violations (without any liability to Lessor or the holders
of the Instruments for which such parties are not indemnified by the Lessee) or
waivers or settlements of all claims, liabilities and damages resulting
therefrom, or (iii) make such changes, including alteration or removal, to the
Improvements and take such other action as shall be reasonably necessary to
rectify such encroachments, violations, hindrances, obstructions or impairments,
subject to the Lessor's consent if and to the extent required by paragraph 10(a)
hereof.

        (c)   The Lessee shall give the Lessor and the Paying Agent at least ten
(10) Business Days' notice prior to any scheduled maintenance or reconditioning
which requires shutdown of operations of the anhydrous ammonia production
facility described on Schedule 3 to the InterParty Agreement for a period of
time in excess of five (5) Business Days.

        10.  Additional Improvements; Removal.  (a)  At any time, so long as no
Default, Event of Default or Unwind Event shall have occurred, the Lessee may,
at its own expense, make Additional Improvements to the Property or any part
thereof; provided, however, that (i) the fair market value of the Property prior
to the construction of the Additional Improvements shall not be lessened
thereby; (ii) such Additional Improvements shall not diminish the capacity,


                                      11
<PAGE>   15
efficiency or useful life of the Improvements which exist prior to the
construction of the Additional Improvements; and (iii) such work shall
be completed in a good and workmanlike manner free and clear of any Liens for
labor, services or materials and in compliance with all
applicable Legal Requirements and Insurance Requirements.  Nothing in this
paragraph 10(a) shall prevent the Lessee from making whatever
changes may be required by Legal Requirements or Insurance Requirements or from
proceeding with the Water Separation Project.

        (b)  The Lessee shall be permitted at any time during, or upon the
expiration or termination of, the Term, and at its sole cost and expense, to
remove or demolish any Additional Improvements to the Property in accordance
with prudent industry practices; provided, however, that, any such removal shall
not (i) impair the intended use or reduce the fair market value of the Property
or any part thereof below its fair market value immediately prior to the
construction of the Additional Improvements (ii) diminish the capacity,
efficiency or useful life of the Improvements or any part thereof below the
capacity, efficiency or useful life as of the commencement of the Term; or (iii)
cause a violation of any Legal Requirement or Insurance Requirement or
significantly increase any risk of liability under any Environmental Law or any
risk to human health or the environment.  Any damage to the Property or any part
thereof caused by such removal or demolition shall promptly be repaired by the
Lessee and the Property or any part thereof shall be restored to its condition
(or the reasonable equivalent thereof) as it existed immediately prior to the
construction of such removed Additional Improvements, at the Lessee's sole cost
and expense.  The Lessee may place upon the Parcel or any part thereof any
inventory, fixtures, machinery, equipment or other property belonging to the
Lessee or third parties and remove the same at any time during the Term and at
the request of the Lessor shall remove the same at the expiration or termination
hereof unless the Lessee shall have purchased the Property pursuant to the terms
hereof; provided that any damage to the Property or any part thereof caused by
such removal shall promptly be repaired by the Lessee, and the Property or such
part thereof restored to its condition (or the equivalent thereof) as it existed
immediately prior to the placement of any such property upon the Parcel, all at
the Lessee's sole cost and expense.

        (c)  The Lessee shall notify the Lessor and the Paying Agent of any
Additional Improvements, the cost of which is anticipated to exceed in the
aggregate $1,000,000 in any calendar year with respect to the Property, which
notice shall include a reasonably detailed description of the work that will be
done.  All Additional Improvements shall become and remain part of the Property
of the Lessor and shall be subject


                                      12
<PAGE>   16
to this Lease, unless and until removed by the Lessee in accordance with
paragraph 10(b).

        11.  Lessee's Right to Contest Real Property Taxes.  The Lessee, at its
own cost and expense and in compliance with paragraph 18, shall have the sole
right, at any time, to seek a reduction in the assessed valuation of the
Property or any part thereof or to contest any real property taxes for the
Property or any part thereof.  Lessor shall not be required to join in any
proceeding or contest brought by Lessee unless the provisions of any Legal
Requirement require that the proceeding or contest be brought by or in the name
of the owner of the Property.  In that case Lessor shall join in the proceeding
or contest or permit it to be brought in Lessor's name as long as Lessee
indemnifies the Lessor for any and all costs and expenses incurred by Lessor in
connection therewith.  Lessee, on a final non-appealable determination of the
proceeding or contest, shall immediately pay, discharge and satisfy any decision
or judgment rendered, together with all costs, interest, additions to tax and
penalties incidental to the decision or judgment.

        12.  Expropriation and Casualty.  (a)  General.  The Lessee hereby
irrevocably assigns to the Lessor any award or compensation or insurance
proceeds (other than general public liability insurance proceeds and business
interruption insurance proceeds) or other payment (including, without
limitation, any indemnity payments payable by the Seller pursuant to the Asset
and Share Purchase Agreement and the Assignment Agreement as the result of any
damage to or destruction of, or any other diminution of the value of, the
Property or any part thereof) to which the Lessee may become entitled by reason
of its interest in the Property or any part thereof if (i) the Property or any
part thereof is damaged or destroyed by fire or other casualty (each, a
"Casualty") or (ii) the use, occupancy or title of the Property or any part
thereof is taken or requisitioned or sold in, or on account of any actual or
threatened condemnation, expropriation or eminent domain proceedings, or other
action by any Person having the power of expropriation (each, an
"Expropriation").  Such awards, compensation, insurance proceeds or other
amounts paid in connection with any such Expropriation or Casualty, as the case
may be, are hereinafter collectively called the "Proceeds".  The Lessor and the
Lessee covenant that if any Expropriation Proceeding shall be commenced, they
shall cooperate in order to obtain the maximum expropriation award to which each
is entitled at law, and subject to the terms of this Lease, the respective
rights of the Lessor and the Lessee shall be governed by the provisions of the
Expropriation Act (Ontario); provided, however, that nothing in this sentence
shall be interpreted as affecting the Lessee's obligation to pay the full Offer
Purchase Price for the Property when required pursuant to paragraph 12(b)
hereof.


                                      13
<PAGE>   17
        The Lessee shall promptly notify the Lessor and the Paying Agent in
writing of any such Casualty or Expropriation and shall appear in any proceeding
or action to defend, negotiate, prosecute or adjust any claim for any award or
compensation or insurance proceeds or other payment on account of any Casualty
or Expropriation and shall take all appropriate action in connection with any
Casualty or Expropriation, including the employment of counsel reasonably
satisfactory to the Lessor.  The Lessor shall have the right to appear and
participate and to employ counsel in any such proceeding or action, and the fees
and expenses of such counsel shall be paid by the Lessee.  If the Lessee shall
elect not to appear in or shall fail to prosecute diligently such proceeding or
action, the Lessor may assume the prosecution thereof and the Lessee shall pay
all of the costs and expenses of the Lessor (including, but not limited to, fees
and expenses of Lessor's counsel) and the fees and expenses of the Special
Counsel.  No settlement of any such proceeding or action shall be made by the
Lessee or the Lessor without the written consent of the other party hereto,
which consent shall not unreasonably be withheld or delayed.

        The Proceeds shall be paid over to the Proceeds Trustee (as defined
below) to be held in trust by such Proceeds Trustee and distributed pursuant to
paragraph 12 or pursuant to the InterParty Agreement and paragraph 15 hereof, as
appropriate, (all such Proceeds, less the costs and expenses incurred by the
Lessor and the Lessee in collecting such amounts, but including any
reimbursement by the Lessee for costs and expenses in connection therewith to
which the Lessor and the holders from time to time of the Instruments are
entitled pursuant to this Lease or the other Operative Documents, are the "Net
Proceeds").  Any and all Proceeds received by the Lessee in connection with any
such proceeding or action shall be received and held in trust for the benefit of
the Lessor, shall be segregated from other funds of the Lessee and shall be
forthwith paid over to the Proceeds Trustee.  The Lessee and the Lessor agree
that this Lease shall control the rights of the Lessor and the Lessee in any
such Proceeds, and any present or future Law to the contrary is hereby waived.
Any and all reasonable charges, fees and expenses of the Proceeds Trustee shall
be paid from the Net Proceeds.  "Proceeds Trustee" shall mean the Paying Agent
or such Canadian chartered bank or trust company as may be designated by the
Lessor, with the consent of the Purchasers.

        (b)  Expropriation or Casualty with Termination.

                (i)  If a Casualty or an Expropriation shall in the good faith
        opinion of the Lessee affect the Property in such a manner as to render
        it unsuitable for restoration or for continued use, in whole or in part,


                                      14
<PAGE>   18
        and occupancy by the Lessee for the intended purposes hereof, then 
        the Lessee  may deliver to the Lessor and the Paying Agent, not later 
        than  thirty (30) days after such occurrence a written notice (herein 
        called a "Termination Notice") describing the event giving rise to such
        termination and describing the status of any proceeding or action and 
        the amount of any Proceeds received or expected to be received in
        connection therewith, together with the date, or anticipated date, of 
        such receipt; or

                (ii)  If an Expropriation or Casualty shall result in damage to
        or the destruction or taking of all or part of the Property representing
        twenty-five percent (25%) or more of the fair market value prior to such
        Casualty or Expropriation, as determined pursuant to the Appraisal
        Procedure, of the Property, then the Lessee shall be deemed to have
        delivered a Termination Notice to the Lessor and the Paying Agent as of
        the date of such occurrence. Either the Lessor, the Paying Agent or the
        Lessee may initiate the Appraisal Procedure by submitting a written
        request that an appraiser be appointed.

                (iii)  Simultaneously with the delivery of a Termination Notice
        pursuant to clause (i) above, the Lessee shall deliver, or in the case
        of clause (ii) above shall be deemed to have delivered, to the Lessor
        and the Paying Agent written notice of its offer to purchase the
        Property (each, an "Offer to Purchase"), and the provisions of
        paragraphs 14 and 15 shall apply.

        (c)  Expropriation or Casualty Without Termination.  If, after a
Casualty or Expropriation, the Lessee has not given or been deemed to have given
a Termination Notice in accordance with subparagraph 12(b), then this Lease
shall continue in full force and effect, and the Lessee shall, at its sole cost
and expense, promptly commence and diligently pursue to completion the
rebuilding, replacement and repair of any damage to the Property caused by such
event in conformity with the requirements of paragraphs 9 and 10, as applicable,
in order to restore the Property (in the case of an Expropriation, as nearly as
practicable) to the value and operating condition (assuming Lessee's compliance
with the terms of this Lease prior to the occurrence of the Expropriation or
Casualty) thereof immediately prior to such event.  In connection with such
restoration the Lessee shall, before beginning such restoration, submit plans
and specifications for such restoration, together with an estimate of the cost
thereof, and all necessary construction contracts therefor for the Lessor's and
the Independent Engineer's approval, which will not be unreasonably withheld;
provided that (i) the capacity, efficiency and useful life of the Improvements,
shall not, after such restoration, be less than the capacity, efficiency and
useful life prior to such


                                      15
<PAGE>   19
Casualty or Expropriation; (ii) the fair market value of the Property shall
not, after such restoration, be less than its fair market value
prior to such Casualty or Expropriation and (iii) if the estimated cost to
complete such restoration exceeds the amount of Net Proceeds, the
Lessor is, in its sole judgment, satisfied that the Lessee shall have
sufficient funds (the "Excess Funds") available to pay such excess, which
Excess Funds shall be deposited by the Lessee with the Proceeds Trustee and
distributed to the Lessee as hereinafter provided.  Such work shall
be completed in a good and workmanlike manner free and clear of all Liens for
labor, services or materials and in compliance with all
applicable Legal Requirements and Insurance Requirements.  All fees and
expenses of the Independent Engineer in connection with any rebuilding
and restoration shall be at the Lessee's sole cost and expense.

        The Lessee shall be entitled to receive payment from the Net Proceeds or
the Excess Funds, as the case may be, from time to time as such work of
rebuilding, replacement or repair progresses, but only after presentation of
certificates of the Independent Engineer, delivered by the Lessee to the
Proceeds Trustee (with a copy to the Lessor and the Paying Agent) from time to
time as such work of rebuilding, replacement or repair progresses.  Each such
certificate of the Independent Engineer shall describe the work for which the
Lessee is requesting payment and the cost incurred by the Lessee in connection
therewith and shall state that such work has been properly completed and that
the Lessee has not theretofore received payment for such work, and shall be
accompanied by an Officer's Certificate of the Lessee certifying that no
Default, Event of Default or Unwind Event has occurred and is continuing and
that the undisbursed Net Proceeds and Excess Funds held by the Proceeds Trustee
are adequate to complete such rebuilding, replacement or repair in accordance
with the requirements of this paragraph 12(c).  The Proceeds Trustee shall
deliver, or cause to be delivered, payment within ten (10) days after its
receipt of the certificates required above.  In connection with such payments,
the Proceeds Trustee shall first disburse all Excess Funds for the cost of such
restoration prior to disbursing any Net Proceeds.  Upon receipt by the Proceeds
Trustee (with a copy to the Lessor and the Paying Agent) of an Officer's
Certificate from the Lessee, to the effect that final payment has been made for
any such work and stating that the rebuilding, replacement or repair has been
completed in compliance with the terms and conditions of this Lease, the
Proceeds Trustee shall deliver payment of any remaining costs incurred by the
Lessee in connection therewith and the remaining amount of such Net Proceeds, if
any, shall be paid to the Lessee.  The Lessee shall be responsible for the cost
of any repair, rebuilding or restoration of the Property in excess of Net
Proceeds and


                                      16
<PAGE>   20
Excess Funds, for which cost the Lessee shall make adequate provision
acceptable to the Lessor.

        (d)  Temporary Expropriation or Lease Termination.  Notwithstanding any
provision to the contrary contained in this paragraph 12, in the event of any
temporary Expropriation this Lease shall remain in full force and effect, and
provided no Default, Event of Default or Unwind Event has occurred and is
continuing, the Lessee shall be entitled to receive the Net Proceeds allocable
to such temporary Expropriation, except that if this Lease shall expire or
terminate during such temporary Expropriation, then Lessee shall be entitled to
the Net Proceeds allocable to the period after the termination or expiration of
this Lease only if it has paid the Offer Purchase Price for the Property.

        13.  [Intentionally Omitted.]

        14.  Lessee Options.  (a)  At any time during the Term but prior to
exercising its options pursuant to paragraph 27(a) hereof, Lessee may (unless
otherwise required to do so, in which case it shall) deliver to Lessor and the
Paying Agent an Offer to Purchase the Property upon and subject to the
applicable terms of this Lease.

        (b)  Any Offer to Purchase delivered or deemed to be delivered by the
Lessee shall, notwithstanding anything to the contrary set forth therein, be
irrevocable and unconditional and shall set forth the Termination Value (as
defined in Schedule C hereto) for the Property to be paid by Lessee.

        (c)  The Lessor shall promptly accept any Offer to Purchase the
Property. The procedure for the purchase of the Property and the purchase price
therefor shall be governed by paragraph 15 hereof.

        15.  Procedure Upon Purchase.  (a)  If the Lessee shall deliver an Offer
to Purchase pursuant to paragraph 27(a)(i), the date of the closing of the
Lessee's purchase of the Property (the "Closing Date") shall be the Expiration
Date.  Otherwise, the Closing Date shall be on the first Payment Date occurring
at least fifteen (15) Business Days following (i) the date of Lessor's
acceptance of such Offer to Purchase; or (ii) if the Lessee has paid over to the
Paying Agent the Offer Purchase Price pursuant to paragraph 19(h) hereof, the
date on which Lessee delivers a request for a Closing Date.  On the Closing
Date, upon receipt of the Offer Purchase Price, the Lessor shall convey, or
cause to be conveyed, the Property (or, in the case of Casualty or
Expropriation, the remaining portion thereof) to the Lessee or its nominee by an
appropriate transfer/deed of land in form suitable for registration containing
no representation or


                                      17
<PAGE>   21
warranty (expressed or implied) except that the Property or such
remaining portion, is free and clear of any encumbrance, mortgage, lease, or
Lien or other adverse interest of any kind created or caused by the Lessor or
any Person claiming by, through or under the Lessor (except Permitted
Encumbrances and except in connection with the arrangements contemplated by the
Operative Documents or as otherwise consented to or created or caused by the
Lessee and except as to any interest created by the Lessor upon the exercise of
any right hereunder upon any Event of Default or Unwind Event).

        (b)  Notwithstanding any provisions of this Lease or the InterParty
Agreement to the contrary, Lessee shall not be required to acquire title to the
Property until such time that all necessary filings and notifications under the
HSR Act shall have been made (including any filing or provision of required
additional information or documents) and the waiting period referred to in the
HSR Act applicable to such purchase shall have expired or been terminated
(without any objection or prohibition of such purchase).  Lessee hereby
covenants to use its best efforts to secure the prompt termination of such
waiting period without objection or prohibition.  Notwithstanding the foregoing,
if the Lessee is precluded from acquiring the Property pursuant to the HSR Act,
Lessee shall pay the Offer Purchase Price within the time and in the manner
described in this paragraph 15 as a consequence of an obligation of Lessee's
exercise or deemed exercise of its purchase option pursuant hereto and the
Lessor shall have no obligation to convey the Property unless the Lessee is no
longer precluded from purchasing the Property.  However, if the Lessee pays the
Offer Purchase Price for the Property in compliance with the preceding sentence,
then the Lessee shall be entitled to continue to lease the Property for an
additional rental payment of $1 per annum and otherwise under the terms and
provisions of this Lease including Lessee's obligation to pay Additional Rent
and other amounts payable hereunder, for an extended term expiring on the
earlier to occur of (i) three (3) years from the date the Lessee delivers (or is
deemed to have delivered) the Offer to Purchase or (ii) the date that the Lessee
is no longer precluded from purchasing the Property pursuant to the HSR Act.  If
the Lessee does not purchase the Property prior to the expiration of such
extended term, the Lessor shall, at the direction of the Lessee, thereafter sell
the Property and distribute the proceeds from such sale in accordance with the
InterParty Agreement.

        (c)  On the Closing Date, the Lessee shall pay, or cause to be paid, to
the Paying Agent the Termination Value for the Property, as specified in the
Offer to Purchase related thereto, plus (without duplication) all Fixed Rent
then due and payable and other sums then due and payable hereunder relating to
the Property or pursuant to the


                                      18
<PAGE>   22
Operative Documents up to and including such Closing Date plus (without
duplication) all Closing Costs (as hereinafter defined) (such amounts, are
herein collectively referred to as the "Offer Purchase Price"), and the Lessor
shall simultaneously (i) deliver to the Lessee or its nominee (A) a
transfer/deed of land in form suitable for registration with respect to the
Property and any other instruments reasonably necessary to convey to the Lessee
or its nominee the Property and assign any other related property then required
to be assigned pursuant hereto, and included in such transfer/deed of land
shall, if requested by Lessee, be the statements contemplated by clauses
50(22)(a) and (b) of the Planning Act (Ontario), contemplated by the Lessor and
the Lessor's Counsel, (B) a statutory declaration of the Lessor that the Lessor
is a resident of Canada within the meaning of the Income Tax Act (Canada), or a
Certificate of the Minister under that section, failing which the Lessee shall
be credited towards the Offer Purchase Price with the amount, if any, which it
shall be necessary for the Lessee to pay to the Receiver General Of Canada in
order to satisfy the Lessee's liability in respect of tax payable by the Lessor
under the non-residency provisions of the Income Tax Act (Canada) by reason of
the sale, and (C) an agreement executed by the Lessor (and to be executed by the
Lessee) in registrable form terminating the Lease, and (ii) convey, or cause to
be conveyed, to the Lessee or its nominee any Net Proceeds related to the
Property and/or the right to receive the same.  "Closing Costs" means all
charges incident to such conveyance, including fees and disbursements of Special
Counsel, Lessor's counsel and Paying Agent's counsel and escrow fees,
registration fees, broker's fees, any fees, costs or expenses incurred by the
Lessor and the Paying Agent in connection with the same and with the release of
the Declaration, and all applicable land transfer taxes and registration fees
which may be imposed by reason of such conveyance and the delivery of said
instruments.

        (d)   Upon the completion of any purchase of the Property pursuant to
this paragraph 15, but not prior thereto, this Lease shall terminate except with
respect to obligations and liabilities of the Lessee actual or contingent which
have arisen with respect to the Property on or prior to the Closing Date and
except as otherwise expressly provided herein.

        15A.  Lessee's Option to Purchase Urea Plant.  (a)  At any time during
the Term but prior to exercising its options pursuant to paragraph 27(a) hereof,
Lessee may deliver to Lessor an offer to purchase the urea processing plant and
related improvements (the "Urea Plant") described on Schedule 3-A to the
InterParty Agreement (the "Urea Plant Offer") and the Lessor shall accept such
offer and convey the Urea Plant to the Lessee upon and subject to the following
terms and conditions:


                                      19
<PAGE>   23
        (i)   The Lessee shall deliver the Urea Plant Offer to the Lessor six
months prior to the proposed date of purchase which shall be a Payment Date (the
"Urea Plant Closing Date");

       (ii)  The Urea Plant Offer shall be accompanied by an Officer's
Certificate of the Lessee stating that the Lessee intends to spend at least
$5,000,000 for Additional Improvements to the Urea Plant;

      (iii)  The purchase price for the Urea Plant will be $6,100,000  plus
the Urea Plant Closing Costs (the "Urea Plant Purchase Price") payable to the
Paying Agent on behalf of the Lessor on the Urea Plant Closing Date;

       (iv)  No Default or Event of Default or Unwind Event shall have occurred
and be continuing on the date that the Urea Plant Offer is made or on the Urea
Plant Closing Date;

        (v)   Any Urea Plant Offer delivered by the Lessee   shall,
notwithstanding anything to the contrary set forth therein, be irrevocable 
and unconditional; and

       (vi)  The Lessee shall have made arrangements satisfactory to the Lessor
for the provision of such utility services, rights of way, easements and related
rights to the Lessor, at no cost to the Lessor, as may be necessary for the full
and efficient operation of the Facility as an anhydrous ammonia production
facility.

        (b)  On the Urea Plant Closing Date, upon receipt by the Paying Agent of
the Urea Plant Purchase Price and, subject to the following paragraph 15A(c), an
amount equal to the fair market value of the parcel of land related to the Urea
Plant (the "Urea Plant Land"), the Lessor shall convey, or cause to be conveyed,
the Urea Plant and, subject to the following paragraph 15A(c), the Urea Plant
Land to the Lessee by an appropriate transfer/deed of land in form suitable for
registration containing no representation or warranty (expressed or implied)
except that each of the Urea Plant and the Urea Plant Land is free and clear of
any encumbrance, mortgage, lease, or Lien or other adverse interest of any kind
created or caused by the Lessor or any Person claiming by, through or under the
Lessor (except Permitted Encumbrances and except in connection with the
arrangements contemplated by this Lease or by the Operative Documents or as
otherwise consented to or created or caused by the Lessee and except as to any
interest created by the Lessor upon the exercise of any right hereunder upon any
Event of Default or Unwind Event) and shall deliver any other instruments
(including, without limitation, those referred to in paragraph 15(c) to the

applicable) reasonably necessary to convey to the Lessee the Urea Plant Land.

        (c)  After the delivery of a Urea Plant Offer, the Lessee will use
commercially reasonable efforts to obtain prior to the Urea Plant Closing Date
all governmental authorizations necessary to convey to the Lessee the Urea Plant
Land, including, without limitation, the consent and approval required to
subdivide the Parcel under the Planning Act (Ontario), and the Lessor agrees to
take such actions as shall be reasonably requested by the Lessee, and otherwise
cooperate with the Lessee, at the Lessee's sole cost and expense, in connection
with such authorizations. If such authorizations are received prior to the Urea
Plant Closing Date, the Urea Plant Land will be conveyed on the Urea Plant
Closing Date as provided in paragraph 15A(b); otherwise, the conveyance of the
Urea Plant Land will be effected as soon as practicable after such
authorizations are received pursuant to documentation mutually acceptable to the
Lessor and the Lessee for a price equal to the fair market value thereof. From
and after the Expiration Date or the date of any earlier termination of the
Lease if the Lessee has not purchased the Property, the Lessor will lease the
Urea Plant Land to the Lessee for an amount equal to the fair market value of
such rental and on such other terms and conditions as are mutually acceptable to
the Lessor and the Lessee.  The fair market value of the Urea Plant Land will,
for rental and conveyance purposes, be determined by an independent appraiser
selected by the Lessee and acceptable to the Lessor.

        (d)  On the Urea Plant Closing Date (and, without duplication, on any
other date on which the Urea Plant Land is conveyed to the Lessee), the Lessee
shall pay, or cause to be paid, to the Paying Agent on behalf of the Lessor the
Urea Plant Purchase Price and the fair market value of the Urea Plant Land plus
(without duplication) all Fixed Rent and other sums then due and payable
hereunder relating to the Property or pursuant to the Operative Documents up to
and including such Urea Plant Closing Date.  "Urea Plant Closing Costs" means
all charges incident to such conveyance, including fees and disbursements of
Special Counsel, Lessor's counsel and Paying Agent's counsel and escrow fees,
registration fees, broker's fees, any fees, costs or expenses incurred by the
Lessor or the Paying Agent in connection with the same, and all applicable land
transfer taxes and registration fees which may be imposed by reason of such
conveyance and the delivery of all instruments related thereto.

        (e)  The Lessor and the Lessee shall enter into such amendments to this
Lease as may be reasonably necessary or proper in connection with the purchase
of the Urea Plant pursuant to this paragraph 15A.

        16.  Insurance.  (a)  The Lessee will purchase and maintain, or cause to
be purchased and maintained, insurance of the following types and in the
following amounts or in such greater amounts as may become necessary from time
to time to prevent the Lessor, the Lessee, and the holders from time to time of
the Instruments from becoming co-insurers of any loss but in no event in amounts
less than those maintained by the Lessee or its Affiliates for other similar
plants owned and/or operated by them:

          (i)     Property Insurance:  Insurance against physical damage to the
Property and Lessee's leasehold improvements caused by perils now or hereafter
embraced by or defined in a standard "all risks" insurance policy, including,
without limitation, flood and earthquake and business interruption coverage;

          (ii)     General Public Liability Insurance:  Comprehensive general
liability insurance against claims for bodily injury (including death), personal

occurrence for bodily injury (or death) and/or property damage;

          (iii)   Builder's Insurance:  During the period of construction of any
Additional Improvements, builders "all risks" and "general risks" insurance
including, without limitation, flood and earthquake with respect to the Property

Lessee and Lessor and all contractors and sub-contractors, in an amount not less
than the full replacement cost of the Property and such on-site and off-site
work, materials and equipment related thereto in the case of on-site, and with
customary limits in the case of off-site, which policy shall make provision for
vacancy;

          (iv)   Boiler and Machinery Insurance:  Broad form boiler and
machinery insurance on objects defined in a standard broad form boiler and
machinery policy including, without limitation, the Lessee's leasehold
improvements, against accidents (as defined therein), with limits of not less
than an amount equal to the Property Cost, which coverage shall include, without
limitation, loss or damage of whatsoever kind or nature by reason of explosion
or collapse by vacuum or cracking, burning, or bulging of any steam or hot water
boilers, pipes or accessories;

          (v)  Other Insurance:  Such other insurance, including automobile
liability, in such amounts and against such risks, as is either (x) customarily
carried by companies owning, operating or leasing property or conducting
businesses


                                      22
<PAGE>   26
similar and/or similarly situated to the Property and/or the Lessee, or (y)
reasonably requested from time to time by the Lessor or the Paying
Agent.

        Such insurance shall be written by companies selected by the Lessee and
qualified to issue such insurance that are acceptable to the Lessor. Such
insurance shall be in a form acceptable to Lessor and shall name the Lessor and
the holders from time to time of the Instruments and their successors and
assignees, as additional insureds, as their interests may appear.  At the
request of the Lessee, the Lessor may consent, in its sole discretion, to the
modification of the insurance coverages required hereby to reflect coverages
customarily carried and the general availability of insurance at commercially
reasonable premiums.

        (b)(i)  The insurance referred to in clauses 16(a)(i), (iii) and (iv)
for the Property may be a blanket policy and shall (1) at all times be in an
amount at least equal to one hundred percent (100%) of the full replacement cost
value (without depreciation) of the Property and the Lessee's leasehold
improvements, and (2) include a loss payable endorsement in favor of the Lessor
to the effect that any loss or damage under such insurance policies shall be
payable solely to the Paying Agent on behalf of Lessor to be held and applied
pursuant to the terms of this Lease and the InterParty Agreement.

        (ii)  Every policy required under paragraph 16(a) shall:  (1) expressly
(A) provide that it will not be cancelled or terminated or changed except upon
sixty (60) days' prior written notice to the Lessor and the Paying Agent and the
Lessee, except in the case of cancellation or termination due to a lapse for
non-payment, in which case only ten (10) days' prior written notice shall be
required; (B) provide that the interests of the Lessor and the holders from time
to time of the Instruments shall be insured regardless of any breach or
violation by the Lessee of any warranties, declarations or conditions contained
in such insurance or any application therefor; (C) provide that such insurance
shall not be invalidated by any act, omission or negligence of the Lessee or the
Lessor or the holders from time to time of the Instruments, nor by any
foreclosure or other proceedings or notices thereof relating to the Property or
any part thereof, nor by legal title to, or ownership of the Property or any
part thereof becoming vested in or by Lessor or its agents, nor by occupancy or
use of the Property or any part thereof for purposes more hazardous than
permitted by such policy; (D) provide that all insurance claims pertaining to
the Property or any part thereof shall be adjusted by the insurers thereunder
with the Lessee but that the Lessor must consent to any such adjusted claim; (E)
include a waiver of all rights of subrogation against the Lessor and the holders
from time 


                                      23
<PAGE>   27
to time of the Instruments and any recourse against the Lessor or the
holders from time to time of the Instruments for payment of any premiums or
assessments under any policy; and (2) not contain a provision relieving the
insurer thereunder of liability for any loss by reason of the existence of other
policies of insurance covering the Property or any part thereof against the
peril involved, whether collectible or not, if such other policies do not name
the Lessor and the holders from time to time of the Instruments as additional
insureds.  The Lessee shall advise the Lessor and the Paying Agent promptly of
any policy cancellation or any change adversely affecting the coverage provided
thereby. All property damage and liability insurance shall contain provisions
for cross liability and severability of interests as between the Lessor and the
Lessee.

        (c)  The Lessee shall deliver to the Paying Agent (with photocopies
thereof to the Lessor) certificates of insurance and any other documentation
necessary to evidence the existence of all insurance which is required to be
maintained by the Lessee hereunder including descriptions of the previously
mentioned Insurance Requirements not customarily found in a standard insurance
policy as well as descriptions of the exceptions to coverage under such
policies, such delivery to be made (i) on or before the commencement of the Term
hereof, (ii) within thirty (30) days of the issuance of any additional policies
or amendments or supplements to any of such insurance, and (iii) at least thirty
(30) days prior to the expiration date of any such insurance.  The Lessee shall
notify Lessor, the Paying Agent and the holders from time to time of the
Instruments of any nonrenewal of any policy required hereunder and shall cause
each insurer under each policy required hereunder to give the Lessor and the
Paying Agent notice of any lapse under any such policy.  The Lessee shall not
obtain or carry separate insurance concurrent in form, or contributing in the
event of loss, with that required by this paragraph 16 unless the Lessor and the
holders from time to time of the Instruments are named as additional insureds
therein, with loss payable as provided in this Lease.  The Lessee shall
immediately notify the Lessor, the Paying Agent and the holders from time to
time of the Instruments whenever any such separate insurance is obtained and
shall deliver to the Paying Agent (with photocopies thereof to the Lessor) the
certificates of insurance evidencing the same as is required hereunder.

        (d)  The requirements of this paragraph 16 shall not be construed to
negate or modify the Lessee's obligations under Section 10.15 of the InterParty
Agreement.

        17.  Subletting.  (a)  The Lessee shall not sublet the Property or any
part thereof, unless (i) at the time of any such sublease, no Default, Event of
Default or Unwind


                                      24
<PAGE>   28
Event shall have occurred and be continuing; (ii) any such sublease
shall by its terms be expressly made subject and subordinate to the terms of
this Lease; (iii) the Lessee shall provide the Lessor and the Paying Agent 15
days prior to the effective date of such sublease with a conformed copy of the
instrument creating such sublease and (iv) in the case of a sublease to a party
other than an Affiliate of the Lessee, the Lessor has consented to such
sublease.  Notwithstanding the foregoing, Lessor acknowledges that Lessee, as
sublessor, has entered into a sublease (the "Sublease") of even date herewith
with Art Hen, as sublessee, pursuant to which Lessee has sublet to Art Hen those
parts of the Property comprised of the Farm Lands.  Lessor hereby consents to
the Sublease and acknowledges receipt of a copy of same.  Lessee hereby
covenants that it will not amend, modify or replace the Sublease without the
prior written consent of the Lessor.

        (b)  No sublease pursuant to this paragraph 17 shall modify or limit any
right or power of the Lessor hereunder or affect or reduce any obligation of the
Lessee hereunder, and all such obligations shall continue in full force and
effect as obligations of a principal and not of a guarantor or surety, as though
no subletting had been made or occupancy permitted.

        (c)  If the Lessee shall request, in connection with any sublease, that
the Lessor execute an attornment and non-disturbance agreement with respect to
such sublease, the Lessor shall consider each such sublease on a case-by-case
basis and may give its consent to its execution and delivery of an attornment
and non-disturbance agreement.  The Lessee shall not mortgage, pledge or
otherwise encumber its interest in and to this Lease or in and to any sublease
or the rentals payable thereunder without the prior written consent of the
Lessor.  Any sublease made otherwise than as expressly permitted by this
paragraph 17 and any mortgage, pledge or assignment of the Lessee's interest
hereunder or under any such sublease shall be null and void.

        (d)  The Lessor and Lessee acknowledge that part of the Property is
subject to existing leases as follows: (i) a lease dated as of February 1, 1988
between C-I-L Inc. ("CIL"), a predecessor in interest of the Lessor, and Liquid
Carbonic Inc.; (ii) a lease dated March 10, 1986 between CIL and Canadian Liquid
Air Ltd.; and (iii) a lease dated March 5, 1987 between CIL and Canadian Oxygen
Limited (collectively, the "Existing Leases"; Liquid Carbonic Inc., Canadian
Liquid Air Ltd. and Canadian Oxygen Limited are hereinafter collectively
referred to as the "Sub-Tenants").  The Lessor hereby assigns the Existing
Leases and all of the Lessor's rights, benefits and entitlements thereunder to
the Lessee and the Lessee hereby accepts such assignment and covenants and
agrees that during the Term and any extension thereof, it


                                      25
<PAGE>   29
shall perform and fulfill all of the covenants and shall assume all of the
liabilities and obligations of the Lessor contained therein.  It is
the intention of the parties hereto that as a result of such assignment and
assumption the Lessor and the Lessee shall be in the same position
as if the Existing Leases were subleases made between the Lessee and each of
the Sub-Tenants and that all of the Lessee's rights, benefits and
entitlements thereunder shall be automatically re-assigned to the Lessor
without further action on the part of the Lessee, such re-assignment
to be effective immediately upon the termination of this Lease, either upon the
Expiration Date or earlier termination of the Lease.  The
Lessee shall, upon the request of the Lessor, execute and deliver all such
instruments, notices, agreements and documents to the Lessor and
each of the Sub-Tenants as may reasonably be required to effect the foregoing
assignment and assumption and re-assignment upon the termination
of this Lease and generally to carry out the purposes of this paragraph.
During the Term, if no Default, Event of Default or Unwind Event
shall have occurred and be continuing, the Trustee shall not take any steps
without the concurrence of the Lessee to terminate the Existing
Leases, interfere with the Sub-Tenants' quiet possession or otherwise exercise
any rights or remedies of the Lessor under the Existing Leases.

        18.  Permitted Contests.  (a)  So long as no Default, Event of Default
or Unwind Event has occurred, the Lessee shall not be required, nor shall the
Lessor have the right, to pay, discharge or remove any Imposition, or to comply
or cause the Property or any part thereof to comply with any applicable Legal
Requirement or to pay any undischarged or unremoved Lien, as long as the Lessee
shall at its sole cost and expense contest, or cause to be contested, diligently
and in good faith, the existence, amount or validity thereof by appropriate
proceedings; provided, however, that such proceedings shall not (i) in the case
of an unpaid Imposition or undischarged or unremoved Lien, result in the
collection thereof from the Lessor and the holders from time to time of the
Instruments or against the Property or any part thereof, (ii) result in the
sale, forfeiture or loss of the Property or any part thereof, and (iii) in the
case of a Legal Requirement, subject the Lessor or the holders from time to time
of the Instruments to the risk of any criminal liability or civil liability for
failure to comply therewith.  The Lessee shall give such security as may be
reasonably demanded by the Lessor and the Paying Agent to insure ultimate
payment of such Imposition or the discharge or removal of any Lien or to insure
compliance with such Legal Requirement and to prevent any sale or forfeiture of
the Property or any part thereof, or any interference with or deductions from
any Fixed Rent, Additional Rent or any other sum required to be paid by the
Lessee hereunder by reason of such non-payment, non-discharge, non-removal or
non-compliance.


                                      26
<PAGE>   30
        (b)  The Lessor shall cooperate with the Lessee in any contest and shall
allow the Lessee to conduct such contest in the name of the Lessor, if necessary
at the Lessee's sole cost and expense.  The Lessee shall notify the Lessor and
the Paying Agent of each such proceeding at least ten (10) Business Days prior
to the commencement thereof, which notice shall describe such proceeding in
reasonable detail.

        (c)  The Lessee shall, promptly after the final determination (including
appeals) of any contest brought by it pursuant to this paragraph 18, pay and
discharge all amounts which shall be determined to be payable therein and shall
be entitled to receive and retain for its own account all amounts refunded
and/or rebated as a result of any such contest and if the Lessor or the Paying
Agent receives any amount as a result of such contest to which it is not
otherwise entitled pursuant to this Lease, it shall promptly return such amount
to the Lessee.

        18A.  Unwind Event.  Upon payment by the Lessee of the Unwind Fee and
the surrender of the Property pursuant to procedures similar to those specified
in paragraph 15 to the extent applicable, this Lease shall terminate.

        19.  Default and Remedies Provisions.  (a)  Any of the following
occurrences or acts shall constitute an event of default (each, an "Event of
Default") under this Lease:

           (i)   if the Lessee shall fail to pay (a) any Fixed Rent within five
(5) Business Days after the date on which payment is due or (b) any Additional
Rent within five (5) Business Days after the earlier to occur of (x) written
notice that such Additional Rent is due has been given to the Company by the
Lessor, the Paying Agent or any Purchaser and (y) the date on which the Lessee
becomes aware, or reasonably should have become aware, that such Additional Rent
is due or (c) any other sum required to be paid hereunder on the date on which
such payment is due;

           (ii)   subject to paragraph 18, if the Lessee shall fail to pay any
Imposition when such payment shall become due or within any grace period
provided for payment of such Imposition;

           (iii)  if the Lessee shall fail to comply with any Insurance
Requirement or if any insurance policy covering any part of the Property is, or
is threatened to be cancelled or adversely changed as a result of any act or
omission of the Lessee or any Person for whom it is legally responsible;

           (iv)  if the Lessee shall grant, suffer to exist or create any Lien 
(other than Permitted Encumbrances) upon


                                      27
<PAGE>   31
this Lease or the Property or any part thereof or interest therein or upon any
Fixed Rent, Additional Rent or other sum payable hereunder;

        (v)  if the Lessee shall fail to comply with the requirements of
paragraph 27 (b) (i) within the time periods provided therein;

        (vi) if the Lessee has elected to terminate this Lease pursuant to and
in compliance with paragraph 27 (a) (ii) and if, five (5) Business Days before
the Expiration Date either (a) the Company is then rebuilding or restoring 
the Property pursuant to paragraph 12 (c) hereof or (b) a temporary 
Expropriation has occurred and is scheduled to continue after the Expiration 
Date (provided, however, that it shall not be an Event of Default hereunder 
if (A) amount necessary to complete the rebuilding or restoration of the 
Property shall not exceed $1,000,000, or, in the case of a temporary 
Expropriation, the economic loss to the Lessor due to such Expropriation
whether by the diminishment of the fair market value of the Property, as
determined by the Appraisal Procedure, or otherwise, will not exceed
$1,000,000, (B) the Lessor has received such evidence as it reasonably requests
to such effect, (C) such amount has been paid over to the Proceeds Trustee and
(D) the Lessee has provided an indemnity to the Lessor, in form and substance
satisfactory to the Lessor, with respect to any additional amounts necessary to
restore or rebuild the Property or to make up for the economic loss to the
Lessor due to such temporary Expropriation);

        (vii)    if the Lessee shall fail to observe or perform any provision
hereof which is not otherwise listed in this subparagraph 19(a) and such failure
shall continue for thirty (30) days after the earlier of (a) the date on which
the Lessee becomes aware of such failure or (b) notice by the Lessor or the
Paying Agent to the Lessee of such failure;

        (viii)   if an Event of Default shall have occurred under any Operative
Document; or

        (ix)     if the Lessee shall have abandoned the Property or if the
Property becomes vacant for a period of thirty (30) consecutive days.

        (b)  The Lessor may take all steps to protect and enforce the rights of
the Lessor or obligations of the Lessee hereunder, whether by action, suit or
proceeding at law or in equity (for the specific performance of any covenant,
condition or agreement contained in this Lease, or in aid of the execution of
any power herein granted or for any foreclosure, or for the enforcement of any
other appropriate legal or equitable remedy) or otherwise as the Lessor shall
deem necessary or advisable.


                                      28
<PAGE>   32

        (c)     (i)  If an Event of Default shall have occurred and be
continuing, then upon five (5) days' written notice by the Lessor to the Lessee,
in addition to all other rights, remedies or recourses available, the Lessor may
terminate this Lease and the Lessee's right to possession of the Property or any
part thereof.  This Lease and the estate hereby granted shall expire and
terminate at midnight on the fifth (5th) day (or such later date as may be
specified therein) after the date of such notice, as fully and completely and
with the same effect as if such date were the date herein fixed for the
expiration of the Term and all rights of the Lessee shall terminate but the
Lessee shall remain liable as hereinafter provided.

        (ii)  Should the Lessor elect not to terminate this Lease, this Lease
shall continue in full force and effect and Lessor may enforce all Lessor's
rights and remedies under this Lease including the right to recover the Fixed
Rent and Additional Rent as it becomes due under this Lease.  For the purposes
hereof, the following do not constitute a termination of this Lease:

                (A)      Acts of maintenance or preservation of the Property or
        any part thereof or efforts to relet the Property or any part thereof,
        including, without limitation, termination of any sublease of the
        Property and removal of such subtenant from the Property; and/or

                (B)      The appointment of a receiver for the Property upon the
        initiative of the Lessor to protect the Lessor's interest under this
        Lease.

        (d)  If an Event of Default shall have occurred and be continuing, and
in addition to the Lessor's right to terminate this Lease, upon five (5) days'
notice, Lessor shall have (i) the right, whether or not this Lease shall have
been terminated pursuant to paragraph 19(c) hereof, to re-enter and repossess
the Property or any part thereof, as the Lessor may elect, by summary
proceedings, ejectment, any other legal action or in any other lawful manner the
Lessor determines to be necessary or desirable and (ii) the right to remove all
Persons and property therefrom.  The Lessor shall be under no liability by
reason of any such re-entry, repossession or removal.  No such re-entry or
repossession of the Property or any part thereof shall be construed as an
election by the Lessor to terminate this Lease unless a notice of such
termination is given to the Lessee pursuant to paragraph 19(c) hereof, or unless
such termination is decreed by a court or other governmental tribunal of
competent jurisdiction.  Should the Lessor elect to re-enter the Property as
herein provided or should the Lessor take possession pursuant to legal
proceedings or pursuant to any notice provided for by Law or


                                      29
<PAGE>   33
upon termination of this Lease pursuant to paragraph 19(c) hereof or otherwise
as permitted by Law, the Lessee shall peaceably quit and
surrender the Property or any part thereof to the Lessor.  In any such event,
neither the Lessee nor any Person claiming through or under the
Lessee, by virtue of any Law, shall be entitled to possession or to remain in
possession of the Property or any part thereof, but shall
forthwith quit and surrender the Property to the Lessor.

        (e)  At any time or from time to time after the Lessor's re-entry or
repossession of the Property or any part thereof pursuant to paragraph 19(d)
hereof, whether or not this Lease shall have been terminated pursuant to
paragraph 19(c) hereof, the Lessor may (but shall be under no obligation to)
relet the Property or any part thereof, for the account of the Lessee, without
notice to the Lessee, for such term or terms and on such conditions and for such
uses as the Lessor, in its sole and absolute discretion, may determine and to
make alterations to the Property to facilitate such reletting.  The Lessor may
collect and receive any rents payable by reason of such reletting.  The Lessor
shall not be liable for any failure to relet the Property or any part thereof or
for any failure to collect any rent due upon any such reletting.

        (f)  No termination of this Lease pursuant to paragraph 19(c) hereof, or
by operation of Law, and no re-entry or repossession of the Property or any part
thereof, pursuant to paragraph 19(d) hereof, and no reletting of the Property or
any part thereof pursuant to paragraph 19(e) hereof, shall relieve the Lessee of
its liabilities and obligations hereunder, all of which shall survive such
termination, re- entry, repossession or reletting.

        (g)  In the event of any termination of this Lease or of the Lessee's
right to possession of the Property or any part thereof by reason of the
occurrence of any Event of Default, the Lessee shall pay to the Paying Agent all
Fixed Rent and Additional Rent and other sums required to be paid to and
including the date of such termination of this Lease or of the Lessee's right to
possession; and thereafter, until the end of the Term, whether or not the
Property or any part thereof shall have been relet, the Lessee to the extent
permitted by applicable Law shall be liable to the Lessor for, and shall pay to
the Paying Agent on behalf of the Lessor, on the days on which such amounts
would be payable under this Lease in the absence of such termination, re-entry
or repossession as agreed current damages and not as a penalty:  all Fixed Rent,
all Additional Rent and other sums which would be payable under this Lease by
the Lessee, in the absence of such termination, re- entry or repossession, and
all costs (including legal fees and expenses) incurred by the Lessor or the
Paying Agent hereunder (payable on demand) and all costs of any environmental
remediation required by Environmental


                                      30
<PAGE>   34
Law.  To the extent permitted by Law, at such time after the termination or
expiration of this Lease as the Lessee shall have paid all amounts
required to be paid by it under this Lease and the Lessor shall have discharged
any and all obligations to the holders from time to time of the
Instruments, then the Paying Agent on behalf of the Lessor shall pay to the
Lessee, when received, the net proceeds, if any, of any reletting
effected for the account of the Lessee pursuant to paragraph 19(e), after
deducting from such proceeds all the Lessor's and Paying Agent's
expenses in connection with such reletting (including, but not limited to, all
repossession costs, brokerage commissions, legal fees and
expenses, employees' expenses, alteration costs and expenses of preparation for
such reletting and all costs of environmental remediation
required by Environmental Law).

        (h)  Notwithstanding the foregoing, if an Event of Default shall have
occurred, the Lessee may within five (5) Business Days of the earlier of the
Lessor's or the Paying Agent's notice of such occurrence thereafter pay to the
Paying Agent an amount equal to the Offer Purchase Price in which event the
Lessor shall be obliged to convey the Property to Lessee in compliance with
paragraph 15.

        (i)     At any time after any termination of this Lease or re-entry or
repossession of the Property by reason of the occurrence of an Event of Default,
the Lessor shall be entitled to recover from the Lessee, and the Lessee will pay
to the Paying Agent on demand by the Lessor, in lieu of all liquidated damages
in respect of Fixed Rent beyond the date of such demand (but in addition to any
claim for current damages in respect of Fixed Rent prior to the date of such
demand), an amount equal to the Termination Value on the date of such demand
(and upon such payment, the Lessor agrees to transfer the Property to the Lessee
or its nominee).

        20.  Additional Rights.  (a)  No right or remedy hereunder shall be
exclusive of any other right or remedy, but shall be cumulative and in addition
to any other right or remedy hereunder or now or hereafter existing by Law or in
equity and the exercise by the parties hereto of any one or more of such rights,
powers or remedies shall not preclude the simultaneous exercise of any or all of
such other rights, powers or remedies.  Failure to insist upon the strict
performance of any provision hereof or to exercise any option, right, power or
remedy contained herein shall not constitute a waiver or relinquishment thereof
for the future or with respect to a future Default, Event of Default or Unwind
Event.  Receipt by the Lessor or the Paying Agent of any Fixed Rent, Additional
Rent or other sum payable hereunder with knowledge of the breach by Lessee of
any provision hereof shall not constitute waiver of such breach, and no waiver
by the Lessor of any provision hereof shall be deemed to have been made



                                      31
<PAGE>   35
unless made in writing.  The parties shall be entitled to injunctive relief in
case of the violation or attempted or threatened violation of
any of the provisions hereof, a decree compelling performance of any of the
provisions hereof or any other remedy allowed to the parties by Law
or in equity.

              (b)  The Lessee hereby waives and surrenders for itself and all
those claiming under it, including creditors of all kinds, (i) any right and
privilege which they may have to redeem the Property or any part thereof or to
have a continuance of this Lease after termination of the Lessee's right of
occupancy by Law or by any legal process or writ, or under the terms of this
Lease, or after the termination of the Term of this Lease as herein provided
and (ii) the benefits of any Law which exempts property from liability for debt
or for distress for rent.  If the Lessor makes any claim against the property
of the Lessee by way of distress this provision may be pleaded as an estoppel
against the Lessee in any action brought to test the right of the Lessor to
levy such distress.

              (c)  If an Event of Default exists hereunder, the Lessee shall
pay to the Paying Agent on demand of the Lessor, all damages, costs, fees and
expenses including legal fees and expenses on a solicitor and his own client
basis incurred by the Lessor in enforcing its rights under this Lease, or with
respect to any other matter or thing which is the obligation of the Lessee
hereunder or in respect of which the Lessee has agreed to indemnify the Lessor.

              (d)  The parties hereto intend that this agreement shall
constitute a lease of real and personal property and nothing herein contained
nor any acts of the Lessor or the Lessee shall be deemed or construed as
creating any relationship other than the relationship of landlord and tenant or
lessor and lessee arising out of and pursuant to the provisions of this Lease.

              (e)     TIME IS OF THE ESSENCE IN THIS LEASE AND THE TERMS HEREIN
SHALL BE SO CONSTRUED.

              (f)     [Intentionally Omitted.]

              21.  Notices, Demands, and Other Instruments.  All notices,
offers, consents and other instruments given pursuant to this Lease shall be
sent to the parties hereto at the addresses set forth on Schedule 1 to the
InterParty Agreement and shall be given in the manner and shall be effective at
the times and under the terms set forth in Section 10.02 of the InterParty
Agreement; provided that, each of the Lessor and the Lessee may from time to
time specify, by giving not less than fifteen (15) days' prior notice thereof
to the other party (i) any other address in Canada as its address for purposes
of this Lease and (ii) any other Person that is to



                                   32
<PAGE>   36
receive copies of notices, offers, consents and other instruments hereunder;
provided that neither party shall be entitled to designate more
than two other Persons to receive copies of notices hereunder.

              22.  Status Certificate.  Each party hereto shall, at the
reasonable request of the other party hereto, deliver to such other party or as
the other party may direct within five (5) days after it is requested a
certificate stating whether such other party has knowledge of, or has received
notice from any person of, any Casualty, Expropriation, Default, Event of
Default or Unwind Event.

              23.  Surrender, Redelivery.  If, upon the expiration or
termination of the Term of this Lease or the termination of Lessee's possession
of the Property, Lessee or its nominee has not purchased the Property as
provided hereunder, the Lessee shall surrender (i) the Parcel to the Lessor in
the condition in which the Parcel was upon the commencement of the Term hereof
(with the exception that the Property shall have been remediated in accordance
with Section 9.18 of the Asset and Share Purchase Agreement and Section 6.01(j)
of the InterParty Agreement) and (ii) the Improvements in the operating
condition, efficiency and with the useful life, they were or had been upon the
commencement of the Term, except as repaired, rebuilt, altered, added to or
built as permitted or required hereby and except for ordinary wear and tear.
To the extent that the Property is not in compliance with the above upon such
expiration or termination, the Lessee shall pay to the Paying Agent on behalf
of the Lessor such additional amounts as are required to place it in compliance
therewith, including the cost of any necessary environmental remediation.  The
Lessee shall also surrender the Property to the Lessor free and clear of all
Liens, easements, consents and restrictive covenants and agreements affecting
the Property which the Lessee is obliged hereunder to remove.  The Lessee shall
also surrender the Property in a condition such that the Property is in
compliance with all applicable Environmental Laws at surrender (irrespective of
whether the deadline for such compliance would otherwise expire before the end
of the Term).  Nothing contained in this paragraph 23 shall relieve or
discharge or in any way affect the obligation of the Lessee to cure promptly
pursuant to this Lease any violations of Legal Requirements referred to in this
Lease, or to pay and discharge as required by this Lease any Liens and
Impositions against the Property.  Lessee shall cooperate, to the fullest
extent, with the Lessor, its subsequent lessees, operators or purchasers to
effect the transfer of all of Lessee's intellectual property, know-how, manuals
and Applicable Permits required for the operation of the Property to such
Persons.  The Lessee, at its sole cost and expense, shall remove from the
Property on or prior to the thirtieth (30th) day following such expiration or
termination all property


                                      33
<PAGE>   37
situated thereon which is not owned by the Lessor and shall repair any damage
caused by such removal and shall restore the Property to the condition and
working order (or reasonable equivalent thereof) in which they existed
immediately prior to the installation of such property, except for ordinary
wear and tear.  Lessee shall indemnify and hold harmless the Lessor, its
successors and assigns against any loss, liability or claim arising out of the
Lessee's removal of such property from the Property.  Any such property of the
Lessee not so removed shall become the property of the Lessor, and the Lessor
may cause such property to be removed from the Property and disposed of, and
the cost of any such removal and disposition of the Lessee's property and of
repairing any damage caused by such removal and of the restoration of the
Property to the condition and working order (or reasonable equivalent thereof)
in which it existed immediately prior to the installation of such property,
ordinary wear and tear excepted, shall be borne by the Lessee.  The obligations
of the Lessee under this paragraph 23 shall survive the expiration or any
termination of this Lease (whether by operation of Law or otherwise) for all
matters described herein which occur or arise prior to such expiration or
termination or arise out of or result from facts, events, claims, liabilities,
actions or conditions occurring, arising or existing on or before such
expiration or termination.

              24.  Separability; Binding Effect; Governing Law.  (a)  Each
provision hereof shall be separate and independent and the breach of any such
provision by the Lessor shall not discharge or relieve the Lessee from its
obligations to perform each and every covenant to be performed by the Lessee
hereunder.  If any provision hereof or the application thereof to any Person or
circumstance shall be invalid or unenforceable, the remaining provisions
hereof, or the application of such provision to persons or circumstances other
than those as to which it is invalid or unenforceable, shall not be affected
thereby, and each provision hereof shall be valid and shall be enforceable to
the extent permitted by Law.  All provisions contained in this Lease shall be
binding upon, inure to the benefit of, and be enforceable by, the respective
permitted successors and assigns of the Lessor and the Lessee to the same
extent as if each successor and assignee were named as a party hereto.  The
Lessee may not assign its rights hereunder or any interest herein except in
accordance with paragraph 17 hereof.  The Lessor may assign all or any part of
the Property and/or its rights under this Lease.  This Lease may not be
changed, modified or discharged except by a writing signed by the Lessor and
the Lessee in compliance with the requirements for the same under the
InterParty Agreement.  Any change, modification or discharge made otherwise
than as expressly permitted by this paragraph 24 shall be null and void.  THIS
LEASE SHALL BE GOVERNED BY AND INTERPRETED IN ACCORDANCE WITH THE LAWS OF THE
PROVINCE


                                      34
<PAGE>   38
OF ONTARIO AND THE LAWS OF CANADA APPLICABLE THEREIN.  Jurisdiction hereunder
shall be governed by the provisions governing jurisdiction set forth in Section
10.23 of the InterParty Agreement, which provisions are hereby incorporated
herein, mutatis mutandis, by reference as if fully set forth herein.  This
Lease may be executed in any number of counterparts, each of which shall be an
original, and all of which together shall constitute but one and the same
instrument; provided, however, that this Lease, when delivered, shall
constitute an original, fully enforceable counterpart for all purposes.

              25.  No Recourse.  No recourse shall be had against the Lessor or
any holder of any Instrument or their employees, agents, beneficiaries or
shareholders, for any claim based on any failure by the Lessor in the
performance or observance of any of the agreements, covenants or provisions
contained in this Lease and in the event of any such failure, recourse shall be
had solely against the Property or the proceeds therefrom; provided, however,
that nothing contained in this paragraph 25 shall be taken to prevent
enforcement of (i) any right of the Lessee to injunctive relief under paragraph
20(a) hereof or (ii) any claim against the Lessor or any other Person arising
out of or in connection with this Lease based on fraud, gross negligence or
willful misconduct of the Lessor and nothing shall prevent enforcement against
any other Person to which any part of the Property shall have been transferred,
or by whom any obligations in respect of the Property shall have been
undertaken or assumed in writing; provided, further, that no recourse shall be
made against the Property or the Trust Estate or the proceeds therefrom or any
Holder of an Instrument for any claim against the Lessor or any Person arising
out of or in connection with this Lease based on fraud, gross negligence or
willful misconduct of the Lessor, or arising out of or in connection with a
breach of the Lessor's obligations under the Operative Documents, unless such
claim arises from any action or failure to act by the Lessor which was directed
or consented to by the Majority Holders of the Instruments.

              26.  Lessor's Right to Cure Lessee's Default.  If the Lessee
shall fail to make any payment or perform any act required to be made or
performed under this Lease, the Lessor, without waiving any default or
releasing Lessee from any obligation, may (but shall be under no obligation to)
make such payment or perform such act for the account and at the expense of the
Lessee, and may enter upon the Property for such purpose and take all such
action thereon as, at the Lessor's sole discretion, may be necessary or
appropriate therefor.  No such entry shall be deemed an eviction of the Lessee
or a breach of the Lessor's covenant for quiet possession pursuant to paragraph
2(b) hereof.  All sums so paid by the Lessor or the Paying Agent and all costs
and


                                      35
<PAGE>   39
expenses (including, without limitation, legal fees and expenses so incurred,
together with interest thereon to the extent permitted by Law)
shall be paid by the Lessee to the Paying Agent on demand by the Lessor as
Additional Rent.

              27.     Lessee's Options Upon Expiration.          (a)  In
addition to its rights under paragraph 14 hereof, Lessee shall, by notice given
not less than twelve (12) months prior to the Expiration Date, elect to (i)
deliver an Offer to Purchase the Property and purchase the Property as of the
Expiration Date against payment of an amount equal to the Offer Purchase Price,
in which case the transfer of the Property shall be governed by the terms of

Expiration Date upon payment to the Lessor on the Expiration Date of Fixed
Rent, Additional Rent and any other amounts then due and payable to the Lessor

              (b)     (i)      Upon the election of the Lessee to terminate

Lessee, to or for the benefit of the Lessor and the holders of the Instruments,

     of the Environmental Consultant's report on its audit, the scope of which

     irrespective of the Property's compliance with any and all Legal
     Requirements); the status of the remedial action undertaken by the Seller
     pursuant to the Asset and Share Purchase Agreement as established by such
     audit shall be satisfactory to the Lessor and the Purchasers in their sole
     discretion.

        (F)  If the Lessee has purchased the Urea Plant pursuant to paragraph
15A hereof, the Trustee and the Lessee shall have entered into such  reciprocal
services agreements or arrangements between the Urea Plant  and the Facility as
shall be satisfactory to the Trustee and the  Purchasers, in their sole
discretion.  Such services agreements and  arrangements shall provide for such
matters as, without limitation,  (i) the granting of necessary utility
services, rights of way,  easements and related rights by the Urea Plant to the
Facility and  by the Facility to the Urea Plant, in each case at no cost to the 
recipient, as may be necessary for the full and efficient operation  of the

                                      38
<PAGE>   42
              (b)     (ii)     Upon the Lessee's election to terminate this
Lease pursuant to and in compliance with paragraph 27(a)(ii) hereof, the Lessor
shall have the sole and exclusive right to sell or dispose of the Property and,
as of the Expiration Date, the Lessee shall have no further claim thereto.  The
proceeds of any sale or disposition of the Property pursuant to this paragraph
27(b)(ii) (herein called a "Qualified Sale") shall be applied by the Lessor as
follows:  first, to pay all Closing Costs in connection with the Qualified
Sale; and second, as provided in Section 3.04 of the InterParty Agreement.

              (c)     The Lessee may request that the Lessor extend this Lease
for an additional term of five (5) years (the "Extended Term") and the Lessor
and the Purchasers may agree to extend this Lease in their sole discretion and
upon the mutual agreement of the Lessor and the Lessee as to the amounts and
dates of payment of Fixed Rent for the Extended Term, and upon the Lessee
undertaking to enter into all amendments and supplements to the Operative
Documents and such other agreements as the Lessor in its sole discretion
determines to be necessary and appropriate in connection therewith.  Within
sixty days of receipt of Lessee's request to extend this Lease pursuant to this
paragraph 27, the Lessor and Purchasers shall give notice to the Lessee as to
whether or not such an extension has been granted.  In the event that the
Lessor and the Purchasers do not agree to extend this Lease, the Lessee shall,
within thirty (30) days of such notification, give notice of its alternative
election pursuant to paragraph 27(a)(i) or (ii) hereof.

              (d)     If, after the delivery of notice under paragraph
27(a)(ii), Lessee fails or is unable to satisfy the conditions set forth in
paragraph 27(b)(i) within the time period set forth therein, then Lessee shall
be deemed to have delivered an Offer to Purchase and shall purchase the
Lessor's interest in the Property as of the Expiration Date as provided in
paragraph 15.

              28.  Limitations on Amounts Payable.  Notwithstanding anything to
the contrary contained in this Lease or any of the other Operative Documents,
the amounts which the Lessee is obliged to pay pursuant to this Lease and the
other Operative Documents, and the amounts which Lessor, the Paying Agent and
the Purchasers are entitled to receive pursuant to this Lease and other
Operative Documents, are subject to limitations pursuant to Section 10.18 of
the InterParty Agreement.

              29.  Headings and Table of Contents.  The table of contents and
the headings of the various paragraphs and Schedules of this Lease are for
convenience only and shall not affect the meaning of the terms and conditions
of this Lease.

<PAGE>   43
              30.  Schedules.  Schedules A, B, C and D referred to in this
Lease are hereby incorporated by reference herein.

              31.  [Intentionally Omitted.]

              32.  Registration of Lease.  The Lessor may, in its discretion,
register a notice or copy of this Lease against the Parcel and the Lessee, upon
request of the Lessor, shall join in the execution of a notice of this Lease
solely for the purpose of supporting an application for registration of a
notice of this Lease or any subsequent dealing therewith.  Neither the Lessee
nor anyone on the Lessee's behalf or claiming under the Lessee shall register
this Lease or any other instrument pertaining to this Lease against the Parcel.
Notwithstanding the foregoing but subject to the Lessor's prior written
consent, Lessee shall be entitled to register a document against the Parcel
solely for the purpose of giving notice of this Lease.  The form of notice of
lease shall be prepared by the Lessee's solicitors at the Lessee's cost and
expense, approved by the Lessor and the holders from time to time of the
Instruments and shall describe only:

     (a)      the parties;
     (b)      the Parcel;
     (c)      the date of the Lease;
     (d)      the Term and expiry date of the Lease;
     (e)      any right or option to purchase the Parcel;
     (f)      any option to renew the Lease; and
     (g)      the addresses of the Lessor and the Lessee.

              33.  Partial Payment of Rent.  Acceptance by the Lessor or the
Paying Agent of a lesser amount than the monthly payment of Fixed Rent and
Additional Rent herein stipulated and any endorsement or statement on any
cheque or documentation accompanying any payment of Fixed Rent and Additional
Rent shall not be deemed an acknowledgement of full payment or an accord and
satisfaction, and the Lessor or the Paying Agent on behalf of the Lessor may
accept such payment without prejudice to the Lessor's right to recover the
balance of such Fixed Rent and Additional Rent or to pursue any other remedy
provided in this Lease.

              34.  No Limitation.  Whenever a statement or provision in this
Lease is followed by words denoting inclusion or example (such as "including"
or "such as") and then a list of, or reference to, specific matters or items,
such list or reference shall not be read so as to limit or restrict the
generality of such statement or provision, even though words such as "without
limitation" or "without limiting the generality of the foregoing" do not
precede such list or reference.


                                      40
<PAGE>   44
              35.  Obligations as Covenants.  Each obligation of the Lessor or
the Lessee expressed in this Lease shall be a covenant for all purposes.

              36.  Currency.  All Fixed Rent and Additional Rent and other
amounts of money in this Lease are expressed in and refer to Canadian dollars
and shall be paid in the lawful currency of Canada.

              37.  Survival of Indemnities.  The indemnity provisions of this
Lease and Lessor's rights in respect of any failure of the Lessee to perform
any of its obligations under this Lease shall remain in full force and effect
notwithstanding the expiration or earlier termination of the Term.

              38.  Unavoidable Delay.  Subject to paragraph 5, if and to the
extent that either the Lessor or the Lessee shall be prevented, delayed or
restricted by reason of Unavoidable Delay (as defined below) in the fulfillment
of any obligation hereunder, then either the Lessor or the Lessee, as the case
may be, shall be deemed not to be in default in the performance of such
covenant or obligation and any period for the performance of such obligation
shall be extended accordingly and the other party to this Lease shall not be
entitled to compensation for any loss, inconvenience, nuisance or discomfort
thereby occasioned, provided that in no event will the Lessee be relieved of
its obligation to pay Fixed Rent, Additional Rent or any other sum payable
hereunder or under the other Operative Documents as it becomes due.  For the
purposes of this paragraph, "Unavoidable Delay" means any cause beyond the
control of the party affected thereby which prevents the performance by such
party of any obligations hereunder and not caused by its default or act of
commission or omission and not avoidable by the exercise of reasonable care,
including without limitation strikes, lockouts or other labour disputes, the
enactment, amendment or repeal of any Laws, and shortages or unavailability of
labour materials, but excluding lack of funds or financial inability.

FINANCIAL REVIEW

CONSOLIDATED RESULTS

The Corporation's 1993 income from continuing operations was $22.8 million, or
$0.33 per share, compared with 1992 income from continuing operations of $10.4
million, or $0.15 per share, and 1991 income from continuing operations of
$12.0 million, or $0.18 per share.  The Corporation's 1993 net income was $22.8
million, or $0.33 per share, compared with 1992 net income of $31.0 million, or
$0.45 per share, and a 1991 net loss of $151.7 million, or $2.26 per share.
Net income for 1992 included a credit of $22.3 million, or $0.32 per share, to
recognize the combined effect of changes in accounting for income taxes and
retiree medical benefits.  Losses from discontinued businesses were $1.7
million and $168.8 million in 1992 and 1991, respectively.  The 1991 results
included an extraordinary gain of $5.1 million related to the retirement of
Convertible Subordinated Debentures.

FINANCIAL COMPARABILITY AND OVERVIEW

During 1993, the Corporation expanded its operations through the acquisition of
manufacturing and distribution businesses in Canada.  Properties acquired in
Canada were comprised of the lease of an anhydrous ammonia production and
upgrading facility located near Sarnia, Ontario and ownership interests in 32
farm service centers in Ontario, New Brunswick and Nova Scotia.  Two of the
farm service centers are owned by the Corporation and 30 are operated by
companies in which the Corporation has a 50% ownership interest.  The Canadian
properties, acquired as of March 31, 1993, contributed $98.3 million in
revenues and $8.9 million in net income to the Corporation's 1993 results.

The Corporation also purchased assets associated with 12 farm service centers
in Florida (Terra Asgrow) on December 31, 1993.  This acquisition had no effect
on 1993 results of operations.

During 1992, the Corporation adopted Statement of Financial Accounting
Standards (SFAS) 106, "Employers' Accounting for Post-Retirement Benefits Other
than Pensions" and SFAS 109, "Accounting for Income Taxes."  The cumulative
prior years' effect of these accounting changes as of January 1, 1992 was a
credit of $22.3 million, or $0.32 per share.  The credit resulted principally
from the recognition of income tax benefits expected to be realized by the
Corporation from its net operating loss (NOL) and tax credit carryforwards.
The effect on 1992 income from continuing operations for these changes versus
the methods used in 1991 was a reduction of $7.2 million, or $0.10 per share.

As a result of the decision to focus on agribusiness as its sole operating
segment and a gain on the sale of remaining coal properties discontinued in
1990, the Corporation realized a $2.4 million gain on disposition of
discontinued

operations in 1992.  During 1991, the Corporation realized a loss of $170
million on the sale of its base metals segment for $87 million.

Operating results for 1992 and 1991 (there was no effect on operating results
for 1993) for the base metals, leasing, construction materials, beryllium and
gold businesses have been included in discontinued operations for all periods
presented and were as follows:

</TABLE>

FACTORS THAT AFFECT OPERATING RESULTS

Factors that may affect the Corporation's future operating results include:
the number of planted acres; the types of crops planted; the effects general
weather patterns have on the timing and duration of field work for crop
planting and harvesting; the supply of crop inputs; the relative balance of
supply and demand for nitrogen fertilizers; the availability and cost of
natural gas; management's ability to control selling, general and
administrative expenses; and the availability and cost of financing sources to
fund seasonal working capital needs.

The number of planted acres and the types of crops planted are influenced by
government programs designed to manage carryover stocks and commodity prices of
certain crops.  Due to the higher cost of crop inputs per acre for corn and
cotton, compared with other major crops, changes in corn and cotton acreages
have a more significant effect on the demand for the Corporation's products and
services than changes in other crops.  Significant declines in corn carryover
stocks have lowered 1994 government corn acreage set-asides.  As a result, and
assuming more favorable weather conditions than experienced during 1993, the
U.S.D.A. forecasts and the Corporation expects planted corn acreage to increase
from 74 million acres to 80 million acres in 1994.

Weather can have a significant effect on operations.  Weather conditions that
delay or intermittently disrupt field work during the planting season may
result in fewer crop inputs being applied than normal and/or shift plantings to
crops with shorter growing seasons.  Similar conditions following harvest may
delay or eliminate opportunities
<PAGE>   4
                                                                               
                                                                               4

to apply fertilizers in the fall of the year.  Weather can also have an adverse
effect on crop yields, which lowers the income of the Corporation's customers
and could impair their ability to pay for inputs purchased from the
Corporation.  During 1993, excessive moisture through much of the Midwest
resulted in higher-than-normal unplanted acreage and fewer applications of crop
inputs.  Soil moisture levels remain high in some Midwest areas and early
spring precipitation could disrupt field work during the 1994 planting season.

Reliable sources for supply of crop inputs at competitive prices are critical
to the distribution portion of the Corporation's business.  The Corporation's
sources for fertilizer, agricultural chemicals and seed are typically basic
manufacturers of the products without an internal capability to distribute
products to the North American grower.  The Corporation has entered into
purchase agreements which should ensure an adequate supply of products for its
grower and dealer customers through 1994.

Prices for manufactured fertilizers and feed products are influenced by the
world supply and demand balance for ammonia and nitrogen derivatives and may be
temporarily influenced by regional changes in supply and demand levels.

The principal raw material used to produce nitrogen fertilizer is natural gas.
Natural gas costs comprise almost 50 percent of the total costs and expenses
associated with Manufactured Fertilizer operations.  The Corporation believes
there is sufficient supply of natural gas to allow stable costs over the
long-term and has entered into firm contracts to minimize the risk of
interruption or curtailment of natural gas supplies during the heating season.
At December 31, 1993, the Corporation had fixed prices for approximately 40% of
its 1994 natural gas requirements for its nitrogen fertilizer plants using
supply contracts or financial derivatives.  During 1993, most of the natural
gas used at the Corporation's Courtright plant was obtained pursuant to fixed
price contracts that were considerably favorable compared with U.S. contracts.
The favorable gas supply contracts expired during the 1993 fourth quarter.
Compared with spot prices for natural gas, the Corporation estimates the
Courtright fixed price contracts reduced 1993 costs by $7.0 million.

The Corporation's business is highly seasonal with the majority of sales
occurring during the second quarter in conjunction with spring planting
activity.  Due to the seasonality of the business and the relatively brief
periods products can be used by customers, the Corporation builds inventories
during the first quarter in order to ensure timely product availability during
the peak sales season.  The Corporation's ability to purchase product at
off-season prices and carry inventory until periods of peak demand generally
contributes to gross profits.  For its current level of sales, the Corporation
requires lines of credit to fund inventory increases as well as to support
customer credit terms.  The Corporation believes that its revolving credit
facilities, approximating $156 million, which expire during 1995 are adequate
for expected 1994 sales levels.

RESULTS OF CONTINUING OPERATIONS
1993 COMPARED WITH 1992

CONSOLIDATED RESULTS

The Corporation reported income from continuing operations of $22.8 million, or
$0.33 per share, on revenues of $1,238.0 million in 1993, compared with income
from continuing operations of $10.4 million, or $0.15 per share, on revenues of
$1,082.2 million in 1992.  The 1993 results include nine months of operation of
the Canadian acquisition which added $98.3 million to revenues and $8.9 million
to income from continuing operations.

The Corporation's operations are classified into two major
categories--Distribution and Manufactured Fertilizer.  The Distribution
category includes sales of products purchased from manufacturers and resold by
the Corporation.  Distribution revenues are derived primarily from grower and
dealer customers through sales of chemicals, fertilizer, seed and related
services.  The Manufactured Fertilizer category represents only those
operations directly related to wholesale sales of nitrogen fertilizer and feed
ingredients manufactured at the Corporation's Woodward, Port Neal and
Courtright (Canadian) facilities.

Total revenues and pretax income from continuing operations for the years ended
December 31, 1993 and 1992 by major operating category were as follows:

</TABLE>


DISTRIBUTION

Distribution revenues of $1.02 billion in 1993 increased $60.7 million from
1992 sales or 6.3%.  Approximately $17.7 million of the sales increase
reflected a 3% increase in chemical sales, while the acquisition of the
Canadian business added $20.1 million of the sales increase, or 2.1%.
Distributed fertilizer sales increased $18.3 million and seed revenues
approximated 1992 levels.  Revenue increases in 1993 were less than expected
due to weather conditions, especially the flooding and wet conditions in the
central United States, which reduced planted acres and input application rates.

Operating income for the Distribution business was $16.9 million in 1993,
compared with $16.6 million in 1992.  The acquisition of the Canadian business
added $4.0 million to Distribution operating income.  Domestic operating

                                                                             6


income included a $12.1 million increase in gross profits which was more than
offset by $15.8 million of higher direct selling expenses.  The increase in
gross profits includes $5.4 million from higher sales volumes of chemicals as
well as margin improvements resulting primarily from the Corporation's
increased distribution of its Riverside proprietary brand products.  Gross
profits increased $4.3 million due to higher sales volumes for distributed
fertilizer; gross profits related to sales of other products and services
increased $2.4 million. Increases in 1993 direct selling expenses from 1992
were primarily due to a $8.1 million increase in compensation costs, which
related principally to normal wage increases and additional personnel, and
increased equipment leasing, operating and maintenance expenses of $3.7 million
related to the increased number of locations and excessively wet field
conditions.  Advertising and promotional expenditures increased $1.3 million
from 1992.


MANUFACTURED FERTILIZER
Domestic Manufactured Fertilizer revenues increased 20% to $150.7 million in
1993 from $125.7 million in 1992.  In addition, the acquisition of the Canadian
plant added $78.2 million of manufactured fertilizer sales.  Increased domestic
fertilizer sales volumes added 15% to revenues and higher selling prices for
nitrogen fertilizer and feed products increased revenues by 5%.  The additional
sales volume and higher selling prices were principally the result of increased
demand for nitrogen solution fertilizers which were heavily used in the
shortened planting season.

Operating income for the Manufactured Fertilizer business in 1993 was $28.7
million, compared with $14.8 million in 1992.  The Canadian plant contributed
$9.5 million to the increase in 1993 operating income.  Higher domestic sales
volumes contributed $4.0 million to earnings for 1993.  Expanded domestic
ammonia production and 1992 maintenance turnarounds on both domestic plants
improved 1993 gas conversion efficiency which added $2.0 million to operating
income while excess 1992 turnaround costs of $3.0 million were not repeated.
Higher selling prices for domestic production increased earnings by $6.6
million but were more than offset in 1993 by $11.3 million of cost increases
caused mainly by natural gas price increases.

OTHER OPERATING INCOME
Other operating income was $3.5 million in 1993, compared with a 1992 loss of
$.9 million, as the result of reversing $4.2 million of product liability
reserves expensed in 1989, reflecting the settlement of litigation with DuPont
over the fungicide, Benlate.

NON-OPERATING EXPENSES AND NET INTEREST EXPENSE
Non-operating expenses, which include corporate and unallocated expenses and
interest expense, net of interest income, totaled $16.9 million in 1993,
compared with $12.3 million in 1992.  Corporate and unallocated expenses
increased $4.6 million in 1993 from 1992 as a result of additional interest
expense due to the November 1992 issuance of $30.0 million of unsecured notes
and short-term bond trading losses.

INCOME TAXES
For 1993, the income tax provision rate was lower than statutory rates due to
the utilization of previously unrecognized capital loss carryforwards.  For
federal income tax reporting purposes, the Corporation has remaining NOLs of
$55 million and tax credits of $1.7 million to offset taxable income and
regular tax liabilities, respectively.

LIQUIDITY AND CAPITAL RESOURCES
During 1993, cash was provided primarily through operating activities and the
sale of assets discontinued in prior years and was utilized for two major
acquisitions, the continued upgrading of production facilities, funding of
sales growth and repayment of debt.

Cash was used to fund increases in accounts receivable of $50.8 million and
inventory of $46.4 million, including $26.8 million in accounts receivable and
$30.1 million in inventory related to acquisitions.  Higher fourth quarter 1993
sales than in 1992 caused the majority of the remaining increase in the
accounts receivable balance.  The remaining increases in inventory resulted
from off-season purchases to obtain discounts, increased crop protection
chemicals stocked under the Corporation's Riverside label and higher fertilizer
inventory in anticipation of seasonal price increases.

Asset sales during 1993 generated $24.4 million, including $18.5 million from
the sale of the construction materials business and $5.9 million from the sale
of the remaining leasing business.  Asset sales generated $23.1 million of cash
during 1992, which included $12.0 million from the sale of coal properties and
$10.0 million from the sale of a leasing subsidiary.

The 1993 Canadian acquisition was funded through an operating lease for the
production facilities and $19.9 million in cash.  A $35 million Canadian dollar
revolving credit facility is available to provide for their working capital
needs.  The Terra Asgrow (Florida) purchase was closed December 31, 1993 with
$31.0 million paid from available cash.  Payments for the Canadian and Florida
acquisitions included $20.5 million for non-current assets.

Purchases of property, plant and equipment totaled $21.6 million in 1993
compared with $17.6 million in 1992.  Except for $6.9 million spent for a
methanol manufacturing plant at the Woodward, Oklahoma facility, the 1993
capital expenditures were for routine replacements of property, plant and
equipment and service center expansions.  The Corporation expects 1994 capital
expenditures to approximate $27 million, of which $8 million relates to
completing the methanol manufacturing plant.  The remaining $19 million of
capital expenditures will be used for routine replacements of property, plant
and equipment, expansion of service centers, and efficiency improvements at the
fertilizer production plants.

Repayment of long-term debt during 1993 and 1992 was limited to scheduled
repayments.  Consolidated debt, including the portion due within one year, as a
percentage of total capital was 35% at December 31, 1993 and 38% as of December
31, 1992.  During 1992, the Corporation issued $30 million of long-term debt
through a private placement to be used for general operating purposes.

In July 1993, the Board of Directors authorized a share repurchase program for
up to 2.0 million shares.  During 1993, 106,900 shares were repurchased for
$0.5 million.  In November 1993, the Board of Directors declared a $0.02 per
share regular quarterly dividend.  This will represent a 1994 cash outlay of
$5.6 million, which will be funded from current operations.

The ratio of current assets to current liabilities at December 31, 1993 was
2.1, unchanged from December 31, 1992.  The Corporation's current ratio will
generally decline through June as seasonal increases in inventories and
receivables are funded by increases in current liabilities.


Current financial resources are expected to be adequate to meet normal
requirements during 1994.  Cash balances at December 31, 1993 were $65.1
million, of which $13.0 million is used to collateralize letters of credit
supporting recorded liabilities.  The Corporation has a $130 million revolving
credit facility to fund seasonal increases in inventories and receivables.  The
facility expires December 31, 1995.  Credit agreements outstanding at December
31, 1993 contain certain restrictions, which are described in Notes 8 and 10 to
the Consolidated Financial Statements.  In addition, these agreements restrict
the transfer of cash and other assets from certain operating subsidiaries to
the Corporation.

The Corporation plans to grow internally and through acquisitions.  Management
believes the present working capital position combined with projected cash
flows and available borrowing capacity will be sufficient to meet anticipated
cash requirements for operating needs, capital expenditures and expansion
strategies.


RESULTS OF CONTINUING OPERATIONS
 1992 COMPARED WITH 1991

CONSOLIDATED RESULTS

Income from continuing operations was $10.4 million, or $0.15 per share, for
1992 compared with $12.0 million, or $0.18 per share, for 1991.  The 1992
income tax provision was $6.7 million higher than in 1991 primarily as the
result of the Corporation's change in accounting for income taxes.  The
Corporation recorded 1992 income from continuing operations before income taxes
of $18.2 million compared with $13.1 million in 1991.  Total revenues were
$1,082.2 million in 1992 compared with $1,022.6 million in 1991.

DISTRIBUTION

Distribution revenues of $958.7 million in 1992 increased $59.4 million from
1991 sales of $899.3 million.  Chemical sales increased $64.7 million, or 11%,
during 1992 principally as the result of increased sales volumes in the market
area that covers Mississippi, Arkansas, Tennessee, Louisiana and portions of
Missouri.  Within this market area, demand for cotton insecticide showed the
largest increase.  Retail fertilizer volumes increased $14.1 million, or 7%, in
1992 due to increased application rates and market share growth.  Total
distributed fertilizer sales declined, however, due to the expiration of a
dealer supply agreement for phosphate fertilizers and a 4% reduction in selling
prices.  Seed sales increased $4.6 million, or 10%, over 1991 levels.

Operating income for the Distribution business was $16.6 million in 1992,
compared with $10.0 million in 1991.  The increase in 1992 operating income
reflected a $12.4 million increase in gross profits offset by a 5%, or $5.8
million, increase in direct selling expenses.  The higher gross profits
resulted primarily from increased sales volumes as overall gross margins
approximated 1991 levels.  Increases in 1992 direct selling expenses from 1991
were primarily due to a $4.7 million increase to compensation costs that
reflected normal wage increases, higher medical benefit costs and added
headcount.  Expenses compared with 1991 also increased by $1.0 million as the
result of the accounting change to recognize retiree medical costs over the
employee's service period.

MANUFACTURED FERTILIZER

Manufactured Fertilizer revenues totaled $125.7 million in 1992 compared with
$126.7 million in 1991.  Selling prices for fertilizer and feed ingredients
manufactured by the Corporation declined by $2.3 million, or 2%, in 1992 due
primarily to a higher proportion of off-season sales of ammonia, when prices
are generally lower.  The pricing reductions were partially offset by increased
ammonia volumes.

Operating income for Manufactured Fertilizer operations declined $11.9 million
to $14.8 million in 1992 from $26.7 million in 1991.  Lower selling prices
combined with a 10% increase in natural gas costs reduced 1992 operating income
by $7.5 million.  Natural gas costs increased significantly over 1991 levels
during the last six months of
<PAGE>   10
                                                                           10

1992 as the result of lower industry-wide inventories and increased regulatory
tariffs.  Manufacturing costs for 1992 were also increased by $3.0 million for
higher-than-anticipated costs of maintenance turnarounds at both nitrogen
production facilities.  Manufacturing costs for 1991 were reduced $1.3 million
by insurance proceeds.

NON-OPERATING EXPENSES AND NET INTEREST EXPENSE

Non-operating expenses, which include corporate and unallocated expenses and
interest expense, net of interest income, totaled $12.3 million in 1992
compared with $21.5 million in 1991.  Corporate and unallocated expenses
declined to $4.8 million in 1992 from $8.9 million in 1991 primarily as the
result of the August 1991 closing of the New York corporate office.  Interest
expense was reduced from $14.4 million in 1991 to $10.6 million in 1992 due to
lower seasonal borrowings, the retirement of $31.4 million of Convertible
Subordinated Debentures during the last half of 1991, scheduled debt repayments
and lower interest rates.  Interest income increased to $3.1 million in 1992
from $1.8 million in 1991 due to higher average cash balances as the result of
1991 asset sales.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS



1.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of presentation:
The Consolidated Financial Statements include the accounts of Terra Industries
Inc., formerly Inspiration Resources Corporation, and all majority-owned
subsidiaries (the Corporation).

Operating results and, where appropriate, other data presented for prior years
have been reclassified to reflect discontinued operations described in Note 4.

Business segment:
The Corporation operates in the agribusiness industry through its wholly owned
subsidiary, Terra International, Inc., a marketer and producer of fertilizer,
crop protection products, seed and services for agriculture.

Foreign Exchange:
Results of operations for the Canadian subsidiary are translated using average
currency exchange rates during the period, while assets and liabilities are
translated using current rates.  Resulting translation adjustments are recorded
as currency translation adjustments in stockholders' equity.

Cash and short-term investments:
The Corporation considers short-term investments with an original maturity of
three months or less to be cash equivalents which are reflected at their
approximate fair value.

Inventories:
Inventories are stated at the lower of cost or estimated net realizable value.
The cost of inventories is determined using the first-in, first-out method.

Property, plant and equipment:
Expenditures for plant and equipment additions, replacements and major
improvements are capitalized.  Related depreciation is charged to expense on a
straight-line basis over estimated useful lives.  Maintenance and repair costs
are expensed as incurred.

Reclassifications:
Certain reclassifications have been made to prior years' financial statements
to conform with current year presentation.

Per-share results:
Earnings-per-share data are based on the weighted average number of Common
Shares that would become outstanding after allowing for the full exchange of
Hudson Bay Mining and Smelting Co., Limited Special Shares held by the public
and exercise of outstanding stock options.  All previously unexchanged Special
Shares were automatically exchanged for Common Shares of the Corporation on
July 6, 1993.  The dilutive effect of the Corporation's outstanding restricted
shares, stock options and convertible debentures was not significant.


2.       ACQUISITIONS

On April 8, 1993, a wholly owned subsidiary of the Corporation, Terra
International (Canada) Inc. (Terra Canada) acquired rights to an anhydrous
ammonia manufacturing plant and related upgrading facilities (the nitrogen
plant) located at Courtright, Ontario effective as of March 31, 1993.  In
addition, Terra Canada purchased working capital associated with the nitrogen
plant and interests in 32 farm service centers operating under the trademark,
Agromart(TM).  All but two

                                                                          16

of the Agromarts(TM) are owned by corporations in which Terra Canada has a 50%
interest, and the remaining 50% interests are owned by local management and
other investors.  The remaining two Agromarts(TM) are wholly owned by Terra
Canada.  The amount paid in connection with the transaction was approximately
$73 million (Cdn) of which approximately $47 million (Cdn) was provided through
lease financing and the remainder was funded by a working capital line of
credit and cash.

On December 31, 1993, Terra International, Inc. purchased net assets of certain
operations of Asgrow Florida Company, Inc. (Terra Asgrow Florida), a
distributor of fertilizer, chemicals and seed, for $39 million.  Terra Asgrow
Florida operates 12 distribution centers and is a supplier to the vegetable and
ornamental markets, mostly in Florida.  The amount paid at closing was
approximately $31 million which was provided from available cash.

Terra Canada's operating results from the date of acquisition are included in
the Consolidated Statements of Income.  The following represents unaudited pro
forma summary results of operations as if both acquisitions had occurred at the

The pro forma operating results were adjusted to include lease expense rather
than depreciation for the nitrogen plant, increased costs of seed sales,
amortization of intangibles, interest expense on the acquisition borrowings and
the effect of income taxes.

The pro forma information listed above does not purport to be indicative of the
results that would have been obtained if the operations were combined during
the above period.  In addition, they are not intended to be a projection of
future operating results or trends.


3.       ACCOUNTING CHANGES

In 1992, the Corporation adopted Statement of Financial Accounting Standard
(SFAS) 106, "Employers Accounting for Post-Retirement Benefits Other than
Pensions" and SFAS 109, "Accounting for Income Taxes."  In connection with the
adoption of SFAS 106, the Corporation elected to recognize immediately the
prior service cost of providing post-retirement medical benefits during the
active service of the employee.  This resulted in a one-time charge of $5.7
million, net of income taxes of $3.5 million.  Net income from continuing
operations for 1992 was reduced $0.7 million from that which would have been
reported under the Corporation's previous accounting method.  The pro forma
effect of the change on prior years is not determinable.  Prior to 1992, the
Corporation recognized expense in the period the benefits were paid.  These
benefit costs were not significant in 1991.

Accounting for income taxes under SFAS 109 requires recognition of deferred tax
assets and liabilities for the effect of future tax consequences of events
recognized in the Corporation's financial statements or tax returns.  SFAS 109
requires the Corporation to recognize the income tax benefit of operating loss
and tax credit carryforwards expected to be realized; such recognition was
prohibited under SFAS 96, the Corporation's previous method of accounting for
income taxes.  A $28.0 million credit was recorded as the effect at January 1,
1992 of a change in accounting principle.  Income tax expense from continuing
operations was increased $6.5 million for 1992 pursuant to SFAS 109.

4.       DISCONTINUED OPERATIONS

During 1993, the Corporation sold the leasing business and the construction
materials businesses, discontinued in 1992.

As of December 31, 1992, the Corporation's Board of Directors approved plans to
sell the leasing and construction materials businesses as well as equity
interests in a copper alloy producer, an undeveloped beryllium mine property
and its gold mining affiliate.  As a result of this decision and a gain on the
sale of remaining coal properties, discontinued in 1990, the Corporation
realized a $2.4 million gain on disposition of discontinued operations during
1992.

During the 1991 third quarter, the Corporation sold its interests in its base
metals segment consisting of Hudson Bay Mining and Smelting Co., Limited (HBMS)
and related metals marketing and trading operations.  The base metals segment
was sold to Minorco, the Corporation's majority stockholder, for $87 million.
The Corporation recognized a $170 million loss on the disposal of the base
metals segment.

Financial results of the base metals, coal, leasing and other discontinued
businesses for 1993 have been applied against their respective reserves and
1992 and 1991 amounts have been included in discontinued operations and are as
follows:

5.       RELATIONSHIP WITH MAJORITY STOCKHOLDER

Minorco, through its beneficial ownership of Common Shares, owns approximately
53 percent of the equity of the Corporation.  In 1992, the Corporation
discontinued its remaining operations in the gold mining business conducted
through its 50 percent interest in Western Gold Exploration and Mining Company,
Limited Partnership (WestGold).  The remaining 50 percent interest is owned by
Minorco.  During 1991, the Corporation sold its base metals segment to Minorco
as described in Note 4.  The Corporation subleases office space to Minorco,
procures certain insurance coverages for Minorco and related companies and
shares the cost of an executive of both organizations.  Payments in settlement
of these services are made on an ongoing basis.

worth, adhere to maximum debt leverage limitations and restrict payments to the
Corporation from operating subsidiaries.  The Corporation's $130 million
revolving credit agreement expires December 31, 1995.  A commitment fee of 1/4
percent is paid on the unused portion of the facility, and no borrowings were

$2.3 million, $2.3 million, $2.8 million, $1.3 million and $6.5 million,
respectively.

The Corporation's 8.5 percent Convertible Subordinated Debentures (Debentures)
are convertible into Common Shares any time prior to maturity, unless
previously redeemed, at a conversion price of $8.083 per share.  The Debentures
are subject to redemption, upon not less than 20 days notice by mail, at any
time, as a whole or in part, at the election of the Corporation.  The
redemption price, expressed as a percent of the principal amount of the
Debentures to be redeemed, is 103.40% until May 31, 1994, 102.55% until May 31,
1995 and decreasing yearly thereafter to 100% at June 1, 1997.

During 1992, the Corporation entered into a long-term note purchase agreement
of $30 million in 8.48 percent Senior Notes requiring semi-annual payments
through May 1, 2005.  The Corporation has executed interest rate swap
agreements to convert one-half of these notes to LIBOR-based floating rate
instruments.  The interest rate agreements became effective on April 15, 1993
and terminates on April 15, 2003.  The debt agreement includes covenants
similar to the Revolving Credit Agreement described in Note 8 and a requirement
for rental and interest obligations coverage.

The Industrial Development Revenue Bonds due in 2011 are secured by a letter of
credit guaranteed by the Corporation and, along with other long-term debt due
in 2003, by the Corporation's headquarters building located in Sioux City,
Iowa.  

The fair value of long-term debt was established by reference to the
public exchange market for the publicly traded long-term securities of the
Corporation and consideration of redemption provisions.  Estimates of fair
value developed by the Corporation were utilized for other long-term debt.

The Corporation entered a lease financing agreement in connection with the
purchase of an ammonia manufacturing plant and related upgrading facilities
located near Sarnia, Ontario.  The agreement is for a four-year term requiring
annual lease payments of approximately $4.0 million (Cdn).  Terra Canada has an
option to purchase the nitrogen plant during the term of the lease and at
expiration for approximately $47 million (Cdn).  If, at the end of the lease
term, Terra Canada elects not to exercise its purchase option, the Corporation
must pay to the lessor approximately $40 million (Cdn), subject to
reimbursement based on the proceeds realized upon the sale of the nitrogen
plant by the lessor.  Terra Canada has entered into certain agreements in order
to convert its obligations with respect to the nitrogen plant set forth above
from Canadian dollar and fixed rental obligations to U.S. dollar and variable
rental obligations based on interest rate changes tied to LIBOR.

Total rental expense under all leases, including short-term cancelable
operating leases, was approximately $24.7 million, $19.4 million and $18.9
million for the years ended December 31, 1993, 1992 and 1991, respectively.

In 1988, the Corporation formulated a fungicide for E. I. DuPont de Nemours and
Company ("DuPont") at the Blytheville facility.  The fungicide was recalled and
claims in excess of $90 million, plus punitive damages, have been filed by
third parties alleging damages from product use.  During 1993, the Corporation
reached a settlement with DuPont whereby DuPont will assume responsibility for
all related pending product claims and will reimburse the Corporation for
claims previously settled and not reimbursed by insurers.  As a result of this
settlement, reserves established in 1989 to cover expected recall and claims
costs will not be required.  Accordingly, the Corporation reduced 1993 costs in
the fourth quarter by $4.2 million, the remaining amount of such reserves.

A subsidiary of the Corporation has been notified by the United States
Environmental Protection Agency (EPA) that it is a potentially responsible
party (PRP) in the Matter of Valley Chemical Site, Greenville, Mississippi.
Ten other companies have also been named as PRPs.  Based on discussions with
the EPA and review of information from other PRPs, the Corporation believes its
responsibility is limited to a portion of material removal costs which should
not be significant to its operating results.

The Corporation is contingently liable for retiree medical benefits of
employees of coal mining operations sold on January 12, 1993.  Under the
purchase agreement, the purchaser agreed to indemnify the Corporation against
its obligations under certain employee benefit plans.  Due to the Coal Industry
Retiree Health Benefit Act of 1992, certain retiree medical benefits of union
coal miners have become statutorily mandated, and all companies owning 50
percent or more of any company liable for such benefits as of certain specified
dates becomes liable for such benefits if the company directly liable is unable
to pay them.  As a result, if the purchaser becomes unable to pay its retiree
medical obligations assumed pursuant to the sale, the Corporation may have to
pay such amount.  The Corporation has estimated that the present value of
liabilities for which it retains contingent responsibility approximates $12
million at December 31, 1993.  In the event the Corporation would be required
to assume this liability, mineral reserves associated with the sold coal
subsidiary would revert to the Corporation.

                                                                           21

The Corporation and certain of its subsidiaries are involved in the above
mentioned and various other legal actions and claims, including environmental
matters, arising from the normal course of business.  Although it is not
possible to predict with any certainty the outcome of such matters, it is the
opinion of management that these matters will not have a material adverse
effect on the Corporation.


12.      FINANCIAL INSTRUMENTS AND CONCENTRATIONS OF CREDIT RISK

FINANCIAL INSTRUMENTS - The Corporation enters into foreign exchange forward
and option contracts to manage exposure to currency fluctuations.  These
agreements are entered as designated hedges of fixed obligations and hedges of
net foreign currency transaction exposures.  At December 31, 1993, the notional
amounts for all foreign exchange forward and foreign currency option contracts
totaled $98.2 million.  These amounts are a reflection of the extent of such
activity and are disclosed for informational purposes only.  They do not
indicate the significantly smaller credit or economic risks involved in these
agreements.

These contracts had a carrying amount of $0.1 million and a fair value of $0.9
million.  Fair value of foreign exchange forward contracts is based on
quotations received from a quotation service and on computations prepared by
the Corporation which are based on current rates of exchange.  Maturities,
which are consistent with the settlement dates of items being hedged, extend
through April 1997.  The gains and losses on these contracts are deferred and
included as a component of the related transaction.

The Corporation fixes some natural gas supply prices through the use of swap
agreements and financial derivatives.  The Corporation had gas contracts with a
computed value of $24.7 million and a fair value of $24.2 million based on
contract prices and rates in effect at December 31, 1993.  Gains and losses on
futures contracts and swap agreements are credited or charged to manufacturing
cost in the month to which the hedged transaction relates.

At December 31, 1993, the Corporation had letters of credit outstanding
totaling $19.5 million, guaranteeing various insurance and financing
activities.  Short-term investments of $13.0 million at December 31, 1993 and
1992 are restricted to collateralize certain of the letters of credit.

The Corporation enters into the above agreements with a limited number of major
international financial institutions.  The Corporation does not expect any
losses from credit exposure due to review and control procedures established by
corporate policy.

CONCENTRATIONS OF CREDIT RISK - The Corporation is subject to credit risk
through trade receivables and short-term investments.  Although a substantial
portion of its debtors' ability to pay is dependent upon the agribusiness
economic sector, credit risk with respect to trade receivables is minimized due
to a large customer base and its geographic dispersion.  Short-term cash
investments are placed with well capitalized, high quality financial
institutions and in short duration corporate and government debt securities
funds.  By policy, the Corporation limits the amount of credit exposure in any
one type of investment instrument.


13.      STOCKHOLDERS' EQUITY

The Corporation allocates $1.00 per share upon the issuance of Common Shares to
the Common Share capital account.

On July 6, 1993, the outstanding HBMS Special Exchangeable Non-Voting Shares
(HBMS Special Shares) were each automatically exchanged for one Common Share of
the Corporation.  Through the Corporation's Trust Shares, each HBMS Special
Share had a vote equivalent to one Common Share of the Corporation.  For Common
Shares issued upon the exchange of HBMS Special Shares subsequent to August 31,
1986, the Corporation allocated $9.53 per share to the Common Share capital
account, representing the average historical capitalization of the HBMS Special
Shares.

                                                                           22

In 1992, the Corporation issued 375,500 restricted Common Shares under its 1992
Stock Incentive Plan to certain key employees of the Corporation.  During 1993
an additional 38,500 shares were issued and 45,500 shares were forfeited.  At
December 31, 1993, 368,500 of the unvested shares remain outstanding.  Under
terms of the issuance, vesting of stock granted is contingent upon the
attainment, prior to March 1999, of pre-established market price objectives for
the Corporation's shares and/or, for approximately 31 percent of participants,
specified regional or divisional three-year operating profit objectives.  In
1991, the Corporation issued 33,300 restricted Common Shares under its 1987
Stock Incentive Plan.  The agreement restricts the shares to vesting in equal
annual installments over five years.  The shares issued are entitled to normal
voting rights and earn dividends as declared during the performance periods.
Compensation expenses are accrued on ratable bases through the performance
periods.

The Corporation has authorized 16,500,000 Trust Shares for issuance.  All Trust
Shares previously outstanding were cancelled in July 1993.

In addition to the Common and Trust Shares, the Corporation has authorized
19,125,000 Class A Shares for issuance.  All Class A Shares previously
outstanding were converted to Common Shares in 1991.

A summary of changes in the Corporation's outstanding capital stock follows:

At December 31, 1993, 12.5 million Common Shares were reserved for issuance
upon award of restricted shares, exercise of employee stock options and
conversion of convertible debentures.


14.      STOCK OPTIONS

The Corporation's 1992 Stock Incentive Plan authorized granting key employees
options to purchase Common Shares at not less than fair market value on the
date of grant and also authorizes the award of performance units and restricted
shares.  The Corporation's 1983 Stock Option Plan and 1987 Stock Incentive Plan
authorized granting key employees similar options to purchase Common Shares.
No further options may be granted under the 1983 and 1987 Plan.  Awards to a
maximum of 2.5 million Common Shares may be granted under the 1992 Plan.
Options generally may not be exercised prior to one year or more than ten years
from the date of grant.  At December 31, 1993, 1,763,500 Common

15.      RETIREMENT PLANS

The Corporation and its subsidiaries maintain non-contributory pension plans
that cover substantially all salaried and hourly employees.  Benefits are based
on a final pay formula for the salaried plans and a flat benefit formula for
the hourly plans.  The plans' assets consist principally of equity securities
and corporate and government debt securities.  The Corporation and its
subsidiaries also have certain non-qualified pension plans covering
executives, which are unfunded.  The Corporation accrues pension costs based
upon annual independent actuarial valuations for each plan and funds these
costs in accordance with statutory requirements.  The components of net
periodic pension expense (credit) were as follows:

Under the terms of the Canadian purchase agreement, the Corporation established
a pension plan for transferring employees, whereby the seller will transfer
assets, which approximate the projected benefit obligation of $9.8 million.

The assumptions used to determine the actuarial present value of benefit
obligations and pension expense during each of the years in the three- year
period ended December 31, 1993 were as follows:

The Corporation also sponsors a qualifying savings plan covering most full-time
employees.  Contributions made by participating employees are matched based on
a specified percentage of employee contributions to 6% of the employees' pay
base.  The cost of the Corporation's matching contribution to the savings plan
totaled $1.4 million in 1993, and $1.1 million in 1992 and 1991.


16.      POST-RETIREMENT BENEFITS

The Corporation also provides health care benefits for eligible retired
employees of its agribusiness subsidiary.  Participants generally become
eligible after reaching retirement age with ten years of service.  The plan
pays a stated percentage of most medical expenses reduced for any deductible
and payments made by government programs.  The plan is unfunded.

Employees hired prior to January 1, 1990 are eligible for participation in the
plan.  Participant contributions and co-payments are subject to escalation.

The Corporation limits its future obligation for post-retirement medical
benefits by capping at 5% the annual rate of increase in the cost of claims it
assumes under the Plan.  The weighted average discount rate used in determining
the accumulated post-retirement medical benefit obligation is 7.5% and was 8.0%
in 1992.  The determination of the Corporation's accumulated post-retirement
benefit obligation as of December 31, 1993 utilizes the annual limit of 5% for
increases in claims costs.

Effective January 1, 1992, the Corporation adopted SFAS 109 to account for
income taxes as described in Note 3 above.  The Corporation has accumulated net
operating loss (NOL) carryforwards and, in prior years under provisions of its
previous accounting method, the benefits from loss carryforwards had been
included as a reduction of income tax expense in the year utilized.

The income tax provision differs from the federal statutory provision for the
following reasons:

Remaining unutilized NOL carryforwards were approximately $55 million
and $51 million at December 31, 1993 and 1992, respectively.  NOL carryforwards
that have not been utilized expire in 2005.  Investment tax credits of
approximately $1.7 million expire in varying amounts from 1998 through 2000. 
Alternative minimum taxes paid of $5.2 million are available to offset future
tax liabilities and have an indefinite life.  The Corporation's capital loss
carryforwards totalled $7.9 million and $28.1 million at December 31, 1993 and
1992, respectively.  Capital loss carryforwards that are not utilized will
expire in 1997.  The change in  the valuation allowance reflects current
utilization of capital losses against capital gains and changes in tax rates.  A
valuation allowance is provided since the realization of tax benefits of capital
loss carryforwards is not assured.

from continuing operations are as follows:

RESPONSIBILITY FOR FINANCIAL STATEMENTS


The accompanying Consolidated Financial Statements of Terra Industries Inc. and
its subsidiaries have been prepared in conformity with generally accepted
accounting principles appropriate in the circumstances.  The integrity and
objectivity of data in these financial statements and supplemental data,
including estimates and judgments related to matters not concluded by year end,
are the responsibility of management.

The Corporation has a system of internal accounting controls that provides
management with reasonable assurance that transactions are recorded and
executed in accordance with its authorizations, that assets are properly
safeguarded and accounted for, and that financial records are maintained to
permit preparation of financial statements in accordance with generally
accepted accounting principles.  This system includes written policies and
procedures, and organizational structure that segregates duties, and a
comprehensive program of periodic audits by the internal auditors.  The
Corporation also has instituted policies and guidelines that require employees
to maintain the highest level of ethical standards.

The Audit Committee of the Board of Directors is responsible for the review and
oversight of the internal audit function, the financial statements and
reporting practices of the Corporation.  The Audit Committee meets periodically
with management, internal auditors and the independent accountants.  The
independent accountants and internal auditors have access to the Audit
Committee and, without management present, have the opportunity to discuss the
adequacy of internal accounting controls and to review the quality of financial
reporting.

The Consolidated Financial Statements contained in this Annual Report have been
examined by our independent accountants.  Their examinations included a review
of internal accounting controls to establish a basis for reliance thereon in
determining the nature, extent and timing of audit tests applied in their
examinations of the Consolidated Financial Statements.

INDEPENDENT AUDITORS' REPORT


To the Board of Directors and Stockholders of
Terra Industries Inc.



We have audited the accompanying consolidated statement of financial position
of Terra Industries Inc. and its subsidiaries as of December 31, 1993 and 1992,
and the related consolidated statements of income, cash flows and changes in
stockholders' equity for the years then ended.  These financial statements are
the responsibility of the Corporation's management.  Our responsibility is to
express an opinion on these financial statements based on our audits.  The
financial statements of the Corporation for the year ended December 31, 1991
were audited by other auditors whose report, dated February 13, 1992, expressed
an unqualified opinion on those statements.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audits to
obtain reasonable assurance about whether the financial statements are free of
material misstatement.  An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements.  An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation.  We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, such 1993 and 1992 consolidated financial statements present
fairly, in all material respects, the financial position of the Corporation at
December 31, 1993 and 1992, and the results of its operations and its cash
flows for the years then ended in conformity with generally accepted accounting
principles.

As discussed in Note 3 to the financial statements, the Corporation changed its
method of accounting for post-retirement medical benefits and income taxes
effective January 1, 1992 to conform with Statements of Financial Accounting
Standards No. 106 and 109.
