Items 1 and 2.  BUSINESS AND PROPERTIES.

     Terra Industries Inc., a Maryland corporation, conducts its ongoing
operations primarily through its various subsidiaries. Unless otherwise referred
to herein or the context otherwise requires, references to the "Company" or
"Terra" shall mean Terra Industries Inc., including, where the context so
requires, its direct and indirect subsidiaries. The subsidiaries that are not
wholly owned include two limited partnerships operating the businesses of the
Beaumont Facility in one case and both the Verdigris Facility and the
Blytheville Facility in the other case. Terra is the sole general partner and
majority partner in both partnerships. The principal corporate office of the
Company is located at Terra Centre, 600 Fourth Street, Sioux City, Iowa 51102-
6000 and its telephone number is 712-277-1340.

General

     The Company is a leader in each of its three business segments: (i) the
distribution of crop inputs and services, (ii) the manufacture and marketing of
nitrogen products and (iii) the manufacture and marketing of methanol. The
Company owns and operates the largest independent farm service center network in
North America and is the second largest distributor of crop inputs in the United
States. The Company is also one of the largest producers of anhydrous ammonia
and nitrogen solutions in the United States and Canada. In addition, the Company
is one of the largest U.S. manufacturers and marketers of methanol. The Company
acquired a United Kingdom nitrogen products business (the "U.K. Business") on
December 31, 1997 from Imperial Chemicals Industries Plc ("ICI").

     The Company's distribution network serves the United States and eastern
region of Canada and includes 423 Company operated farm service centers as of
December 31, 1997. In addition, another 100-plus locations are about 40% owned
by the Company through an investment in Royster-Clark, Inc.

     The Company's principal production facilities are comprised of:

        .  seven nitrogen fertilizer plants located in Oklahoma (the "Woodward
           Facility" and the "Verdigris Facility"), Iowa (the "Port Neal
           Facility"), Ontario, Canada (the "Courtright Facility") Arkansas (the
           "Blytheville Facility") and the United Kingdom (the "Billingham
           Facility" and the "Severnside Facility"); and

        .  a methanol production plant located in Texas (the "Beaumont
           Facility") (the Woodward Facility also includes methanol
           production).

     For certain financial information regarding the Company's industry segments
(Distribution, Nitrogen Products and Methanol), see Note 21 to the Company's
Consolidated Financial Statements incorporated herein.

     Terra's long-term strategy for growth is to: (i) acquire and upgrade
production and distribution facilities, (ii) increase distribution volumes by
expanding sales from existing farm service centers, (iii) shift its product mix
to include more profitable products and (iv) continue to build customer loyalty
by providing value-added services. As part of this strategy, in April 1993,
Terra acquired the Courtright Facility and an interest in 32 farm service
centers in Canada; in December 1993, Terra acquired 12 farm service centers in
Florida; in September 1994, Terra acquired a minority interest in a 100-plus
location distributor of crop input and protection products in the mid-Atlantic
region; in October 1994, Terra acquired Agricultural Minerals and Chemicals Inc,
which provided Terra two fertilizer plants having 1.4 million tons of annual
gross production capacity of ammonia, as well as the Beaumont Facility; in July
1996, Terra completed a construction project at its Courtright Facility enabling
the upgrade of an additional 65,000 tons of ammonia annually into urea and
nitrogen solutions (UAN); in May 1997, Terra acquired 18 farm service centers
which include grain operations and are located in or near southern Minnesota; in
November 1997, Terra completed construction of a nitric acid plant at its Port
Neal Facility which increases annual UAN capacity by 320,000

                                       1

tons and on December 31, 1997, Terra acquired the U.K. Business. In addition,
certain other distribution location acquisitions and manufacturing upgrade
projects have been completed during the past few years.

Distribution

     The Company's farm service center network is a distribution and marketing
system for a comprehensive line of fertilizers, crop protection products, seed
and services. The Company's customers are primarily farmers and dealers located
in the midwestern and southern regions of the United States, and the
southeastern region of Canada.

     Products. The Company markets a comprehensive line of crop protection
products (herbicides, insecticides, fungicides, adjuvants, plant growth
regulators, defoliants, desiccants and other products), fertilizer (nitrogen,
phosphates, potash and micronutrients) and seed.

     Although most crop protection products marketed by the Company are
manufactured by unaffiliated suppliers, the Company also markets its own
Riverside(R) brand products. Riverside(R) products represented approximately 13%
of the Company's total crop protection product sales in 1997. As of December 31,
1997, the Riverside(R) line included approximately 210 products, of which 11
were added in 1997. The Riverside(R) line of products consists of herbicides,
insecticides, fungicides, adjuvants, seed treatments, plant growth regulators,
defoliants and desiccants. The majority of Riverside(R) products are formulated
or packaged in facilities owned in whole or in part by the Company. The
Riverside(R) line includes several formulations produced exclusively by the
Company, but does not include patented agricultural chemicals. Riverside(R)
products generally provide higher margins for the Company than products
manufactured by unaffiliated suppliers. The sale of such products, however,
involves additional indirect costs, including the cost of maintaining inventory,
disposing of excess inventory and potentially greater liability for product
defects. The Company possesses and processes the registrations required by the
EPA for Riverside(R) pesticide products.

     The Company markets several major seed brands and, in its United States
marketing area, is one of the largest independent seed distributors. The Company
focuses marketing efforts on proprietary Terra(R) brand seeds for corn hybrids,
soybean, wheat and cotton varieties, which generally provide higher margins.
These products represented approximately 17% of the Company's total seed sales
in 1997. The Company plans to offer genetically enhanced seeds under the
Terra(R) brand for the 1998 growing season. Biotechnical advances make seeds
more sophisticated by incorporating resistance to specific herbicides or pests,
or enhancing the nutritional characteristics of the crop. The Company also
features DEKALB brand seed in the Midwest.

     Services. In addition to selling products used to grow crops, the Company's
farm service centers offer a wide variety of services to grower customers. These
services include soil and plant tissue analysis, crop production program
recommendations, custom blending of fertilizers, field application services,
field inspections for pest control and crop program performance follow-up.

     The farm service centers utilize the Company's analytical services
laboratory to analyze nutrient levels in soil and plant tissue samples. The
results of these tests are used to provide specific, localized soil fertility
recommendations for specific crops on a field-by-field basis. Recommendations
can be made for practically all crops grown in the Company's markets. The
Company 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.

     Terra has made a commitment to its customers by taking an active role in
precision agriculture. Precision agriculture relies on global positioning
satellites as a navigation aid to site-specific locations in a field for which
various crop response characteristics are identified through soil sampling and
yield monitoring. Variable rate applicators apply prescription rates of various
crop inputs using the information and technology available for precision
agriculture. Growers utilize the technology in their planting and harvesting
equipment and gain more control in crop production decisions. The Company has
invested in hardware, software and personnel to meet the demand of its Precision
in Agriculture(TM) program.

                                       2
<PAGE>
 
     The Company has also entered the grain and feed merchandising business in
connection with several recently acquired farm service centers. Grain marketing
may enhance Terra's effectiveness in helping a grower through the planning,
planting, growing and crop marketing cycle.

     In connection with product sales to dealers, the Company provides
warehousing and delivery services. For selected dealer customers, the Company
offers environmental and safety services, access to the Company's soil and plant
tissue testing laboratory, and other services.

     Marketing and Distribution. The Company markets its products primarily to
agricultural customers, including both dealers and growers. For 1997,
approximately 70% of the Company's distribution revenues were attributable to
grower sales through farm service center locations and approximately 30% were
attributable to sales to dealers.

     The Company also markets its products through its Professional Products(R)
group to non-farm customers, including turf growers, nurseries, golf courses,
parks, athletic facilities and utility companies. The Company offers these
customers herbicides, insecticides, fungicides, fertilizer, adjuvants, plant
growth regulators, seed and agronomic services. The Professional Products(R)
personnel generally utilize the Company's farm service centers for delivery,
billing and other systems and services.

     The Company's distribution operations are organized into Northern, Southern
and Western Divisions, which as of December 31, 1997 are divided into 11
separate geographical regions for management purposes. Field personnel receive
regular training through Terra University, a series of courses designed to
develop skills in agronomy, management, sales, environmental responsibility,
personal safety and crop inputs application. In 1997 Terra implemented a 
company-wide database marketing initiative named LOCALMOTION(TM). This effort
has created a platform for Terra sales representatives to improve communications
with customers by providing timely information specific to their individual
needs as well as aiding the development of tailored product and service
offerings. The field salespeople are supported by an analytical services
laboratory, a staff of technical service representatives and research stations
where the efficacy of various crop protection products and the performance of
numerous seed varieties are tested.

     Properties. The Company's farm service centers are located on a combination
of owned and leased properties and a majority of the buildings and other
improvements thereon are owned in fee. The leases have varying expiration dates
through the year 2007. The Company also leases or, in some cases, owns a number
of additional fertilizer storage facilities and various rolling stock equipment.

     Product Formulations. The Company formulates crop protection products
through its Omnium LLC joint venture, which is jointly owned and controlled with
Farmland Industries Inc. The St. Joseph Formulation Facility formulates liquid
crop protection products and the Blytheville Formulation Facility formulates dry
flowable ("DF") crop protection products. DF formulations are dry, water-
dispersible granules that are mixed with water before application. Liquid
formulations are water based or solvent based products that are also mixed with
water before application. In addition to formulating Riverside(R) products,
these facilities formulate products for Farmland Industries and others. The two
formulation facilities are owned by the Omnium joint venture in fee.

Nitrogen Products

     Nitrogen is one of three primary nutrients essential for plant growth.
Nitrogen fertilizer products must be reapplied each year in areas of extensive
agricultural usage because of absorption by crops and leaching from the soil.
There are currently no substitutes for nitrogen fertilizer in the cultivation of
high-yield crops.

     The Company is a major producer and distributor of nitrogen products,
principally fertilizers. The Company's principal nitrogen products in North
America are ammonia, urea and urea ammonium nitrate solution ("UAN"). The
Company's principal nitrogen products manufactured in the U.K. are ammonia and
ammonium nitrate ("AN"). A
                                       3
<PAGE>
 
significant portion of the Company's ammonia production is upgraded into other
nitrogen fertilizer products such as urea, UAN and AN.

     Products. Although, to some extent, the various nitrogen fertilizer
products are interchangeable, each has its own distinct characteristics which
produce agronomic preferences among end users. Farmers decide which type of
nitrogen fertilizer to apply based on the crop planted, soil and weather
conditions, regional farming practices, relative nitrogen fertilizer prices and
the cost and availability of appropriate storage, handling and application
equipment.

     Ammonia. Anhydrous ammonia is the simplest form of nitrogen fertilizer and
is the feedstock for the production of most other nitrogen fertilizers,
including urea and UAN. It is produced by natural gas reacting with steam and
air at high temperatures and pressures in the presence of catalysts. It has a
nitrogen content of 82% by weight and is generally the least expensive form of
fertilizer per pound of nitrogen. Ammonia has a distinctive odor and requires
refrigeration or pressurization for transportation and storage.

     Urea. Urea is produced for both the animal feed and fertilizer market by
converting ammonia and carbon dioxide into liquid urea, which can be turned into
a solid form. Urea has a nitrogen content of 46% by weight, the highest level
for any solid nitrogen product. The Company produces both solid urea in the
granulated form, generally for the fertilizer market, and urea liquor for animal
feed supplements.

     UAN. The Company produces UAN at all five of its North American fertilizer
manufacturing facilities. The Verdigris Facility in Oklahoma is the largest UAN
production facility in North America. UAN is produced by combining liquid urea
and liquid ammonium nitrate in water. The nitrogen content of UAN is typically
28% to 32% by weight. UAN is a liquid fertilizer and, unlike ammonia, is
generally odorless and does not need to be refrigerated or pressurized for
transportation or storage.

     UAN may be applied separately or may be mixed with various crop protection
products, permitting the application of several materials simultaneously, and
thus reducing energy and labor costs and accelerating field preparation for
planting. In addition, UAN may be applied from ordinary tanks and trucks and can
be sprayed or injected into the soil, or applied through irrigation systems,
throughout the growing season. UAN is relatively expensive to transport and
store because of its high water content. Due to its stable nature, UAN may be
used for no-till row crops where fertilizer is spread upon the surface but may
be subject to volatilization losses. The use of conservation tilling, which
reduces erosion, is increasing in the United States, and the Company believes
this trend, if continued, should increase UAN demand.

     AN. With the acquisition of the U.K. Business, the Company produces AN at
its two plants in England. AN is produced by combining nitric acid and ammonia
into a liquid form which is then turned into a solid. The nitrogen content of AN
is 34.5% by weight. Most of the AN sold by the U.K. Business is for the
fertilizer market.

     The Company's sales mix of its three principal nitrogen products for each
of the last three years (excluding the U.K. Business) was approximately (based
on tons sold):

     Plants. All the Company's plants in North America are integrated facilities
for the production of ammonia, liquid urea and UAN. In addition, the Blytheville
Facility and the Courtright Facility produce granular urea. The Company's two
plants in the U.K. are integrated facilities for the production of ammonia,
nitric acid, ammonium nitrate and liquid carbon dioxide. The following nitrogen
products facilities are operated by the Company:

to operate continuously, except for planned shutdowns (usually biennial) for
maintenance and efficiency improvements. Capacity utilization (gross tons
produced divided by capacity tons at expected operating rates and on stream
factors) of the Company's fertilizer manufacturing facilities (excluding the
U.K. facilities) for each of the years ended December 31, 1997, 1996 and 1995,
in the aggregate, was approximately 103%, 101% and 97%, respectively.

     The Port Neal Facility was the site of a major explosion on December 13,
1994. The Company repaired the facility, with ammonia production resuming in
December 1995 and the urea and UAN upgrading facilities production resuming in
May 1996. The Company settled in 1997 for $321 million its property damage and
business interruption insurance claims associated with this explosion. The
Company further completed in November 1997 a $23 million capital project at the
Port Neal Facility to increase annual nitric acid production which increases UAN
production capacity to 810,000 tons from 490,000 tons. The Company owns the Port
Neal Facility in fee.

     The Woodward Facility includes not only an ammonia plant and a UAN plant,
but also a methanol plant with annual capacity of up to about 40 million
gallons. The Woodward Facility is owned in fee.

     The Courtright Facility's liquid urea and granulation capacities increased
as a result of a $32 million plant upgrade project completed in July 1996. The
project enabled the upgrade of up to an additional 65,000 tons of ammonia
annually into urea and UAN. The Company owns the Courtright Facility in fee, but
this facility is subject to an encumbrance in favor of lenders.

     Located at the Verdigris Facility are two ammonia plants, two nitric acid
plants and two UAN plants and the Port Terminal. The plants are owned in fee by
the Company, while the Port Terminal is leased from the Tulsa-Rogers County Port
Authority. The leasehold interest on the Port Terminal is scheduled to expire in
April 1999, and the Company has the option to renew the lease for two
additional, consecutive terms of five years each.

     The Blytheville Facility consists of an anhydrous ammonia plant, a granular
urea plant and a UAN plant. The UAN plant began production in late 1994. The
ammonia plant at the Blytheville Facility is leased from the City of Blytheville
at a nominal annual rental. The lease term is scheduled to expire in November
1999, and the Company has the option to extend the lease for twelve successive
terms of five years each at the same rental rate. The Company has the
unconditional right to purchase the plant for a nominal price at the end of the
lease term (including any renewal term). The urea plant is also leased from the
City of Blytheville. The lease is scheduled to expire in November 1999, and the
Company has the option to renew the lease for four successive periods of five
years each at a nominal annual rental. The Company also has an option to
purchase the urea plant for a nominal price.

     The Billingham Facility consists of an ammonia plant, three nitric acid
plants, a sodium nitrite plant, an ammonium nitrate plant and a carbon dioxide
recovery unit. The Billingham Facility also provides to customers


                                       5
<PAGE>
 
certain site services and utilities including steam and electricity. The Company
owns the Billingham Facility in fee, but this facility is subject to an
encumbrance in connection with the financing for the purchase of the U.K.
Business.

     The Severnside Facility includes two ammonia plants, two nitric acid
plants, an ammonium nitrate plant and a carbon dioxide recovery unit. This
facility is owned in fee, but it is subject to an encumbrance in connection with
the financing for the purchase of the U.K. Business.

     Terra announced in October 1997 a $57 million capital project to add an
ammonia production loop to its Beaumont Facility. This project is expected to
add 255,000 tons of annual ammonia capacity without reducing methanol capacity.
It is expected to be operational in the fourth quarter of 1999.

     Marketing and Distribution. The Company's principal customers for its
manufactured nitrogen products are independent dealers, national retail chains,
cooperatives and industrial customers. Industrial customers accounted for
approximately 12% of the Company's 1997 total tons of its manufactured nitrogen
products. In 1997, approximately 11% of the Company's fertilizer production
tonnage was supplied to its farm service center locations for sale to growers,
while the rest was sold to outside customers. In 1997, no outside customer
accounted for greater than 5% of total manufactured nitrogen fertilizer
revenues.

     The Company's production facilities, combined with significant storage
capacity in about 60 locations, throughout the Midwestern U.S. and in other
major fertilizer consuming regions allow it to be a major supplier of nitrogen
fertilizers.

     Under an ammonium nitrate agreement with ICI, the Company has agreed to
make payments based on the market price of ammonium nitrate in connection with
the Company's U.K. Business. The Company will be required to make a payment for
each year through 2002 if average ammonium nitrate prices exceed certain
threshholds during any year, subject to maximum payments of (Pounds)58 million
(95.7 million USD) over the term of the agreement. As a result of making any
such payments, the Company will not benefit fully from the U.K. price of
ammonium nitrate over certain thresholds during the term of this agreement.

Methanol

     The Company substantially increased its participation in the methanol
industry in October 1994 with the acquisition of the Beaumont Facility. The
Company has approximately 320 million gallons of annual methanol production
capacity, representing approximately 13% of the total United States rated
capacity in production at the end of 1997.

     Product. Methanol is a liquid petrochemical made primarily from natural
gas. It is used as a feedstock in the production of other chemical products such
as formaldehyde, acetic acid and chemicals used in the building products
industry. Methanol is also used as a feedstock in the production of MTBE, an
oxygenate used as an additive in reformulated gasoline and an octane enhancer
used in non-reformulated gasoline. Reformulated gasoline has lower volatility
and is less aromatic than non-reformulated gasoline. The methanol manufacturing
process involves heating the natural gas feedstock, mixing it with steam and
passing it over a nickel-based catalyst, which breaks it down into carbon
monoxide, carbon dioxide and hydrogen. This reformed gas is then cooled,
compressed and passed over a copper-zinc based catalyst to produce crude
methanol. Crude methanol consists of approximately 80% methanol and 20% water.
In order to convert it to high-purity chemical grade methanol suitable for sale,
the crude methanol is distilled to remove the water and other impurities.

     Plants. In 1994, the Company completed a project for optional production of
methanol, offsetting up to about 25% of the Woodward Facility's ammonia
capacity. The Company has up to about 40 million gallons of annual methanol
capacity at the Woodward Facility, and this facility produced 36 million, 31
million and 34 million gallons in each of 1995, 1996 and 1997, respectively.
This facility is owned by the Company in fee.

                                       6
<PAGE>
 
     The Beaumont Facility is among the largest methanol production plants in
the United States, with approximately 280 million gallons of annual methanol
capacity. This facility produced 263 million, 280 million and 276 million
gallons in each of 1995, 1996 and 1997, respectively. The plant and processing
equipment at the Beaumont Facility are owned by the Company, and the land is
leased from E.I. du Pont de Nemours and Company ("DuPont"), for a nominal annual
rental under a lease agreement which expires in 2090. Because the Beaumont
Facility is entirely contained in a complex owned and operated by DuPont (the
"Beaumont Complex"), the Company depends on DuPont for access to the Beaumont
Facility. The Company also relies on DuPont for access and certain essential
services relating to the wharf located at the Beaumont Complex through which
most of the finished methanol product is shipped to customers. The Company also
depends on DuPont for access to the pipelines used to transport methanol and to
obtain natural gas, as well as for certain utilities, waste water treatment
facilities and other essential services.

     Marketing and Distribution; Contracts. Methanol customers are primarily
large chemical or MTBE producers located in the United States; however, some
product is exported to, for example, Central and South America. The Company has
a number of long-term methanol sales contracts, the most significant of which is
with DuPont. In 1997, the Company sold over 60% of its production under such
contracts. At December 31, 1997, the Company had contracted to sell over 60% of
its 1998 scheduled production at prices indexed to published sources. Most of
these sales contracts (other than the DuPont contract) cover fixed volumes and
have terms of up to three years.

     Under the DuPont contract, as amended, DuPont has agreed to purchase 54
million gallons of methanol each year until 2001 (representing 19% of the
Beaumont Facility capacity). The price for the methanol delivered under the
DuPont contract is generally indexed to a published source. The DuPont contract
will continue in effect after the initial term unless terminated by either party
on two years' notice.

Credit

     A substantial portion of the Company's sales to its grower and dealer
customers is made on credit terms customary in the industry. The Company also
maintains a grower financing program to provide secured, interest-bearing
financing to qualified grower customers for their operating and crop input
requirements on extended payment terms. The Company provided approximately $88
million in 1995, $66 million in 1996 and $65 million in 1997 in credit lines to
grower customers under this program. Although there is additional credit risk
associated with the grower finance program, it is mitigated through a well
defined application, screening and approval process.

     The Company's bad debt experience is affected by the financial condition of
its customers which, in turn, is affected by weather conditions, insect pressure
and other factors. Bad debt write offs were $7.3 million in 1995, $17.9 million
in 1996 and $8.1 million in 1997. The 1996 increase is due principally to two
years of drought conditions in the South and mid-South regions of the U.S.

Seasonality and Volatility

     The crop inputs business is seasonal, based upon the planting, growing and
harvesting cycles. Inventories must be accumulated 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, the Company
can reduce purchases of crop inputs for the distribution portion of its
business, thereby decreasing inventory carrying costs. In the past, over half of
the Company's sales generally occurred during the second quarter of each year.
This seasonality also generally results in higher fertilizer prices during peak
periods, with prices typically reaching their highest point in the spring,
decreasing in the summer, increasing in the fall (as depleted inventories are
restored) through the spring.

     The crop inputs business can also be volatile as a result of a number of
other factors, the most important of which, for U.S. markets, are weather
patterns and field conditions (particularly during periods of high fertilizer
consumption), quantities of fertilizers imported to and exported from North
America and current and projected grain inventories and prices, which are
heavily influenced by U.S. exports and world-wide grain markets. U.S.
governmental policies may directly or indirectly influence the number of acres
planted, the level of grain inventories, the mix of crops planted and

                                       7
<PAGE>
 
crop prices. The U.S. farm bill passed in 1996 put an end to acreage reduction
and production control measures, allowing farmers more flexibility in planting.
Because of factors which are outside of the Company's control, including the
production capacity of competitors, nitrogen fertilizer price levels can be
volatile.

     As with any commodity chemical, the price of methanol can be volatile. The
industry has experienced cycles of oversupply, resulting in depressed prices and
idled capacity, followed by periods of shortage and rapidly rising prices.
During 1994, several factors combined to create a tight market that dramatically
increased prices. Methanol prices from mid-1995 through 1996 remained near
historically "normal" levels. In 1997, methanol prices increased moderately to
the higher end of normal levels due in part to a number of plant shutdowns and
turnarounds. Future demand for methanol will depend in part on the regulatory
environment with respect to reformulated gasoline. Most methanol sold in the
U.S. is sold pursuant to long-term contracts based on market index pricing and a
fixed volume.

Raw Materials

     The principal raw material used to produce nitrogen fertilizer and methanol
is natural gas. Natural gas costs, including transportation and forward pricing
activities, comprised about 50% of the total costs and expenses associated with
the Company's Nitrogen Products segment in 1997. Natural gas costs represented
about 65% of the total costs and expenses associated with its Methanol segment
in 1997. A significant increase in the price of natural gas that is not
recovered through an increase in nitrogen fertilizer or methanol prices could
have a material adverse effect on the Company's profitability and cash flow.

     The Company's natural gas procurement policy is to effectively fix or cap
the price of between 40% and 80% of its natural gas requirements for the
upcoming one-year period and up to 50% of its natural gas requirements for the
subsequent two-year period using supply contracts, financial derivatives and
other forward pricing techniques. Consequently, if natural gas prices were to
increase during this period, the Company may benefit from these forward pricing
techniques, but conversely, if natural gas prices were to fall, the Company may
incur costs above the spot market price as a result of such policies. The
settlement dates are scheduled to coincide with gas purchases during such future
periods. These contracts are based on a designated price, which price is
referenced to market natural gas prices or appropriate NYMEX futures contract
prices. The Company believes that there is sufficient supply to allow acceptable
costs for the foreseeable future and has entered into firm supply contracts to
minimize the risk of interruption or curtailment of natural gas supplies.

     Reliable sources for supply of crop inputs at competitive prices are
critical to the distribution portion of the Company's business. The Company's
sources for fertilizer, agricultural chemicals and seed are typically
manufacturers of the products without an internal capability to distribute
products to the North American grower.

Transportation

     The Company uses several modes of transportation to receive materials and
distribute products to customers and its own locations, including railroad cars,
common carrier trucks, barges, common carrier pipelines and Company-owned or
leased vehicles. The Company utilizes approximately 80 liquid, dry and anhydrous
ammonia fertilizer terminal storage facilities in numerous states and in
Ontario, Canada for both the Distribution and Nitrogen Products segments. The
Company also has varying amounts of warehouse space at each of its farm service
centers and has one methanol storage facility in Beaumont, Texas. For the
Beaumont Facility, the Company transports products primarily by marine transport
via the Neches River to the Intercoastal Canal and the Gulf of Mexico and via
pipeline to selected customers.

     At its North American manufacturing facilities, formulation facilities and
liquid fertilizer storage locations, the Company utilizes railcars as the major
method of transportation. The Company leases approximately 2,500 railcars and
owns ten nitric acid railcars. In England, AN is transported primarily by truck
and ammonia is primarily transported by pipeline. The Company provides some
transportation services to its own facilities and customers as a contract
carrier. The Company uses approximately 90 owner-operators and 14 employee
drivers to deliver fertilizer, crop protection products, seed, feed ingredients
and other products to its own facilities and customers.

                                       8
<PAGE>
 
     The Company transports purchased natural gas for the Woodward Facility and
the Verdigris Facility through an intrastate pipeline that is not an open access
carrier; however, the Company is able to transport gas supplies from any in-
state source connected to this widespread pipeline system, and has limited
access to supplies outside the state. The Beaumont Facility purchases natural
gas on a delivered basis via four intrastate pipelines. 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. The Company transports purchased natural gas for the
Blytheville Facility through a natural gas pipeline company under an agreement
that extends through September 1998. Purchased natural 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, the
Port Neal Facility maintains direct access to its interstate pipeline shipper;
however, the Company has retained its alternative connection to a local utility
service to preserve some flexibility.

Research and Development

     The Company owns and operates an 80-acre research station near its Port
Neal Facility that is utilized for program development, product testing and
demonstration. Product testing and protocols encompass a wide range of subjects,
including: fertilization, weed control, insect control, disease control, crop
varieties and precision agriculture. Corn, soybeans and wheat are the primary
crops grown, with an area set aside for various turf experiments. Trials are
viewed by farmers, dealers, university extension personnel, representatives from
other product manufacturers, investors and Terra employees. Recently, the
emphasis has been placed on examining and viewing the new gene altered or
specific trait corn hybrid and soybean variety production systems.

     Terra conducts an on-going cotton breeding project in the southern U.S. and
has developed several varieties of cotton for grower usage. Experimental corn
hybrids and soybean varieties are observed in numerous U.S. locations to
identify and select Terra(R) brand cotton, corn and soybean lines. Emphasis is
placed on high yielding cotton, corn and soybean lines which also exhibit
herbicide, insect and disease resistance. In addition, Terra technical services
representatives establish various evaluation projects with universities and
private research companies to examine the efficacy of specific Riverside(R)
brand crop protection products that are formulated and marketed by the Company.

Competition

     The market for the fertilizer, crop protection products and seed
distributed by the Company is highly competitive. In 1997, sales attributable to
the Company's farm service centers accounted for roughly 5% of total crop
production products sold in the U.S. Within the specific market areas served by
its farm service centers, however, the Company's share of the market was
substantially higher. The Company's competitors include cooperatives, divisions
of diversified agribusiness companies, regional distributors and independent
dealers, some of which have substantially greater financial and other resources
than the Company. The Company competes in its Distribution business primarily by
providing a comprehensive line of products and what the Company believes to be
superior services to growers and dealers, as well as on price.

     Nitrogen fertilizer is a global commodity and the Company's customers
include end-users, dealers and other fertilizer producers. Customers base their
purchasing decisions principally on the delivered price and availability of the
product. The Company competes with a number of U.S. and foreign producers,
including state-owned and government-subsidized entities. Some of the Company's
principal competitors may have greater total resources and may be less dependent
on earnings from nitrogen fertilizer sales than the Company. Some foreign
competitors may have access to lower cost or government-subsidized natural gas
supplies. Furthermore, as a consequence of favorable market conditions for
nitrogen producers in 1995 and 1996 that stimulated construction of new
projects, additional nitrogen fertilizer manufacturing capacity is being brought
into production. The Company believes that it competes with other manufacturers
of nitrogen fertilizer on delivery terms and availability of products, as well
as on price.

     The methanol industry, like the fertilizer industry, is highly competitive
and such competition is based largely on price, reliability and deliverability
of this global commodity. The relative cost and availability of natural gas and
the

                                       9
<PAGE>
 
efficiency of production facilities are important competitive factors.
Significant determinants of a methanol manufacturing plant's competitive
position are the natural gas acquisition and transportation contracts that a
plant negotiates with its major suppliers. Domestic competitors for methanol
include a number of large integrated petrochemical producers, many of which are
better capitalized than the Company.

Environmental and Other Regulatory Matters

     The Company's operations are subject to various federal, state and local
environmental, safety and health laws and regulations, including laws relating
to air quality, hazardous and solid wastes and water quality. Terra's operations
in Canada are subject to various federal and provincial regulations regarding
such matters, including the Canadian Environmental Protection Act administered
by Environment Canada, and the Ontario Environmental Protection Act administered
by the Ontario Ministry of the Environment. Terra's operations in the U.K. are
subject to similar regulations under a variety of acts governing hazardous
chemicals, transportation and worker health and safety. The Company is also
involved in the manufacture, handling, transportation, storage and disposal of
materials that are or may be classified as hazardous or toxic by federal, state,
provincial or other regulatory agencies. Precautions are taken to reduce the
likelihood of accidents involving these materials. If such materials have been
or are disposed of at sites that are targeted for investigation and remediation
by federal or state regulatory authorities, the Company may be responsible under
CERCLA or analogous laws for all or part of the costs of such investigation and
remediation.

     Terra has been designated as a potentially responsible party ("PRP") under
CERCLA and its state analogues with respect to various sites. Under such laws,
all PRPs may be held jointly and severally liable for the costs of investigation
and remediation of an environmentally damaged site regardless of fault or
legality of original disposal. 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, the Company'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 crop protection product storage facilities present at
the Company's farm service centers and terminals. It is expected that other
states will adopt similar requirements pursuant to federal mandate. The Company
has commenced construction of these facilities at its farm service centers and
terminals, and estimates that the future cost of complying with these
regulations at these locations in 1998 and beyond will be less than $10 million.

     With respect to the Verdigris Facility and Blytheville Facility, Freeport-
McMoRan Resource Partners, Limited Partnership ("FMRP") (a former owner and
operator of such facilities) retained liability for certain environmental
matters. With respect to the Beaumont Facility, DuPont retains responsibility
for certain environmental costs and liabilities stemming from conditions or
operations to the extent such conditions or operations existed or occurred prior
to the 1991 disposition by DuPont. The Company does not believe that such
environmental costs and liabilities, whether or not retained by FMRP or DuPont,
will have a material effect on the Company's results of operations, financial
position or net cash flows.

     Insulation and other construction or building materials at certain Company
plants contain asbestos. Over 400 suits have been filed by contractors'
employees against DuPont based on exposure to asbestos-containing material at
the complex in which the Beaumont Facility is located. At least nine of these
are directly related to the Beaumont Facility. An estimate of potential
liability associated with these suits is not available. DuPont retains
responsibility for all claims based on exposure to hazardous materials,
including asbestos, occurring prior to the 1991 disposition by DuPont. Although
no suit relating to asbestos exposure has been filed against the Company to
date, the possibility exists that liability could be incurred in the future for
claims based on exposure to asbestos-containing material after such acquisition.

     The Company may be required to install additional air and water quality
control equipment, such as low nitrous oxide burners, scrubbers, ammonia sensors
and continuous emission monitors, at certain of its facilities in order to
maintain compliance with Clean Air Act and Clean Water Act requirements. These
equipment requirements are also

                                      10
<PAGE>
 
typically applicable to competitors as well. The Company estimates that the cost
of complying with these requirements in 1998 and beyond will be less than $10
million.
 
     The Company endeavors to comply (and has incurred substantial costs in
connection with such compliance) in all material respects with applicable
environmental, safety and health regulations. Because environmental, safety and
health regulations are expected to continue to change and generally be more
restrictive than current requirements, the costs of complying with such
regulations will likely increase. The Company does not expect its compliance
with such regulations to have a material adverse effect on the Company's results
of operations, financial position or net cash flows.

Employees

     The Company had 4,435 full-time employees at December 31, 1997, with only
the UK employees being covered by anything equivalent to a collective bargaining
agreement. The Company also hires temporary employees on a seasonal basis, and
hired approximately 1,400 temporary employees during the peak of its spring
selling season in 1997.

Item 3.   LEGAL PROCEEDINGS.

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

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

     No items were submitted to a vote of security holders of the Company during
the fourth quarter of 1997.

                       EXECUTIVE OFFICERS OF THE COMPANY

stock, certain transactions with affiliates, incurrence of liens, sale of
assets, and sale-leaseback transactions.

The 10.75% unsecured Senior Notes are redeemable at the option of the
Registrant, in whole or part, at any time on or after September 30, 1998,
initially at 105.375% of their principal amount, plus accrued interest,
declining to 102.688% on or after September 30, 1999, and declining to 100% on
or after September 30, 2000. The 10.75% Senior Notes Indenture contains
restrictions similar to those in the 10.5% Senior Notes Indenture.

3.   Commitments and Contingencies

The Registrant is committed to a non-cancelable office lease expiring in June
1998. Total minimum rental payments are: 1998, $1.7 million. This amount is not
reduced by sublease rentals, which in 1997 was $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 provided reserves equal to the estimated present
value of these liabilities of $20 million at December 31, 1997.

The Registrant had letters of credit outstanding totaling $5.5 million at
December 31, 1997 and $5.4 million at December 31, 1996, guaranteeing various
insurance and financing activities. Short-term investments of $5.4 million at
December 31, 1997 are restricted to collateralize certain of the letters of
credit.

4.   Income Taxes

The Registrant files a consolidated U.S. federal tax return. Beginning in 1995,
the Registrant adopted tax sharing agreements, under which all domestic
operating subsidiaries provide for and remit income taxes to the Registrant
equal to their pretax accounting income, adjusted for permanent differences
between pretax accounting income and taxable income. The tax sharing agreements
allocate the benefits of operating losses and temporary differences between
financial reporting and tax basis income to the Registrant.

compensation of the General Partner).

          (b)  To the extent the General Partner determines such action to be
necessary or reasonable and appropriate, the General Partner shall cause a
certified copy of the Certificate and any amendments thereto to be recorded in
the office of the county recorder in each county in which the Partnership owns
real property.

          (c)  Upon the dissolution of the Partnership, the General Partner (or,
if there is no remaining General Partner, the Liquidator selected pursuant to
clause (b) of the definition thereof set forth in the Appendix attached hereto)
shall promptly execute and cause to be filed certificates of dissolution and/or
certificates of cancellation in accordance with the Act and the law of any other
jurisdictions in which the Partnership has filed a Certificate or has registered
and/or qualified to do business therein.

          SECTION 1.05. Term. The existence of the Partnership as a limited
partnership commenced on the date on which the Certificate was filed in the
office of the Secretary of State of Delaware in accordance with the Act, and
shall continue until the winding up and liquidation of the partnership and its
business and affairs following a Terminating Event, as provided in Article XIII.

          SECTION 1.06. Independent Activities. (a) The General Partner and each
Limited Partner may, except as otherwise expressly provided in this Section
1.06, engage in whatever activities they choose, without having or incurring any
obligation to offer any interest in such activities to the Partnership or any
Partner. Neither this Agreement nor any action undertaken pursuant hereto shall
prevent any Partner or any of its Affiliates from engaging in such activities
(including, without limitation, making and managing Investments and otherwise
engaging in the methanol and/or agricultural minerals industry), or require any
Partner to permit the Partnership or any Partner to participate in any such
activities, and as a material part of the consideration for the execution of
this Agreement by each Partner, each Partner hereby waives, relinquishes and
renounces any such right or claim of participation.

          (b) To the extent permitted under applicable law and except as
otherwise provided in this Agreement, the General Partner, when acting on behalf
of the Partnership, is hereby authorized to purchase property and assets from,
sell property and assets to or otherwise deal with any Partner, acting on its
own behalf, or any Affiliate of any Partner; provided that any such purchase,
sale or other
<PAGE>
 
                                       3

transaction shall be made on terms and conditions which are no less favorable to
the Partnership than if such sale, purchase or other transaction had been made
with an independent third party. The Partners agree that the Transaction
Documents shall satisfy this independent third-party standard and the Partners
hereby authorize the General Partner to cause the Partnership to enter into the
Transaction Documents to which it is or is to be a party.

          (c) Each Limited Partner and any Affiliate thereof may also lend money
to, borrow money from, act as a surety, guarantor or endorser for, guarantee or
assume one or more specific obligations of, provide collateral for, and transact
other business with the Partnership and, subject to other applicable law, has
the same rights and obligations with respect thereto as a Person who is not a
Partner. The existence of these relationships and acting in such capacities will
not result in the Limited Partners being deemed to be participating in the
control of the business of the Partnership or otherwise affect the limited
liability of the Limited Partners.

          SECTION 1.07. Computation of Time Periods. In this Agreement, in the
computation of periods of time from a specified date to a later specified date,
the word "from" means "from and including" and the words "to" and "until" each
mean "to but excluding."

          SECTION 2.03. Separate Business. The Partnership shall keep its
business and affairs and all of the Partnership Property and operations separate
and distinct from the business, affairs, property and assets and operations of
the Partners and of any other Person in which any of them may be or become
interested.

                                  ARTICLE III

                                  ALLOCATIONS


          SECTION 4.01. Profits. Profits for any Allocation Year shall be
allocated in the following manner and order of priority: [Confidential material
has been omitted pursuant to a request for confidential treatment filed with the
Commission under Rule 24b-2(b)and has been filed separately with the
Commission.]

          SECTION 4.02. Losses. Losses for any Allocation Year shall be
allocated in the following manner and order of priority: [Confidential material
has been omitted pursuant to a request for confidential treatment filed with the
Commission under Rule 24b-2(b)and has been filed separately with the
Commission.]

          SECTION 4.03. Special Allocations. (a) Minimum Gain Chargeback. Except
as otherwise provided in Section 1.704-2(f) of the Regulations, notwithstanding
any other provision of this Article IV, if there is a net decrease in
Partnership Minimum Gain during any Allocation Year, each Partner shall be
specially allocated items of Partnership income and gain for such Allocation
Year (and, if necessary, subsequent Allocation Years) in an amount equal to such
Partner's share of the net decrease in Partnership Minimum Gain, determined in
accordance with Section 1.704-2(g) of the Regulations. Allocations pursuant to
the immediately preceding sentence shall be made in proportion to the respective
amounts required to be allocated to each Partner pursuant thereto. The items to
be so allocated shall be determined in accordance with Sections 1.704-2(f)(6)
and 1.704-2(j)(2) of the Regulations. This Section 4.03(a) is intended to comply
with the minimum gain chargeback requirement in Section 1.704-2(f) of the
Regulations and shall be interpreted consistently therewith.
<PAGE>
 
                                       6

          (b) Partner Minimum Gain Chargeback. Except as otherwise provided in
Section 1.704-2(i)(4) of the Regulations, notwithstanding any other provision of
this Article IV, if there is a net decrease in Partner Nonrecourse Debt Minimum
Gain attributable to any Partner Nonrecourse Debt during any Allocation Year,
each Partner who has a share of the Partner Nonrecourse Debt Minimum Gain
attributable to such Partner Nonrecourse Debt, determined in accordance with
Section 1.704-2(i)(5) of the Regulations, shall be specially allocated items of
Partnership income and gain for such Allocation Year (and, if necessary,
subsequent Allocation Years) in an amount equal to such Partner's share of the
net decrease in Partner Nonrecourse Debt Minimum Gain attributable to such
Partner Nonrecourse Debt, determined in accordance with Section 1.704-2(i)(4) of
the Regulations. Allocations pursuant to the immediately preceding sentence
shall be made in proportion to the respective amounts required to be allocated
to each Partner pursuant thereto. The items to be so allocated shall be
determined in accordance with Sections 1.704-2(i)(4) and 1.704-2(j)(2) of the
Regulations. This Section 4.03(b) is intended to comply with the minimum gain
chargeback requirement in Section 1.704-2(i)(4) of the Regulations and shall be
interpreted consistently therewith.

          (c) Qualified Income Offset. If any Limited Partner unexpectedly
receives any adjustment, allocation or distribution described in Section 1.704-
1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5), or 1.704-1(b)(2)(ii)(d)(6) of the
Regulations, items of Partnership income and gain shall be specially allocated,
as promptly as practicable, to each such Limited Partner in an amount and a
manner sufficient to eliminate, to the extent required under the Regulations,
the Adjusted Capital Account Deficit of such Limited Partner; provided that an
allocation pursuant to this Section 4.03(c) shall be made only if and to the
extent that such Limited Partner would have an Adjusted Capital Account Deficit
after all other allocations provided for in this Article IV have been
tentatively made as if this Section 4.03(c) were not included in this Agreement.

          (d) Gross Income Allocation. If any Limited Partner has a deficit in
its Capital Account at the end of any Allocation Year which is in excess of the
sum of (i) the amount such Limited Partner is obligated to restore pursuant to
any provision of this Agreement and (ii) the amount such Limited Partner is
deemed to be obligated to restore pursuant to the penultimate sentences of
Sections 1.704-2(g)(1) and 1.704-2(i)(5) of the Regulations, each such Limited
Partner shall be specially allocated, as promptly as practicable, items of
Partnership income and gain in the amount of such excess; provided that an
allocation pursuant to this Section 4.03(d) shall be made only if and to the
extent that such Limited Partner would have a deficit in its Capital Account in
excess of such sum after all other allocations provided for in this Article IV
have been made as if Section 4.03(c) and this Section 4.03(d) were not included
in this Agreement.

          (e) Nonrecourse Deductions. Nonrecourse Deductions for any Allocation
Year shall be specially allocated Ratably among the Partners.

          (f) Partner Nonrecourse Deductions. Any Partner Nonrecourse Deductions
for any Allocation Year shall be specially allocated to the Partner who bears
the economic risk of loss with respect to the Partner Nonrecourse Debt to which
such Partner Nonrecourse Deductions are attributable in accordance with Section
1.704-2(i)(1) of the Regulations.

          (g) Section 754 Adjustments. To the extent an adjustment to the
adjusted tax basis of any Partnership Property pursuant to Section 734(b) or
743(b) of the Code is required pursuant to Section 1.704-1(b)(2)(iv)(m)(2) or
1.704-1(b)(2)(iv)(m)(4) of the Regulations to be taken into account in
<PAGE>
 
                                       7

determining Capital Accounts as the result of a distribution to a Partner in
complete liquidation of its Interest, the amount of such adjustment to Capital
Accounts shall be treated as an item of gain (if the adjustment increases the
basis of the such Partnership Property) or loss (if the adjustment decreases the
basis of the such Partnership Property), and such gain or loss shall be
specially allocated (i) if Section 1.704-1(b)(2)(iv)(m)(2) of the Regulations
applies, to the Partners in accordance with their Interests, or (ii) if Section
1.704-1(b)(2)(iv)(m)(4) of the Regulations applies, to the Partner to whom such
distribution was made.

          (h) Allocations Relating to Taxable Issuance of Interests. Any item of
income, gain, loss, or deduction realized as a direct or indirect result of the
issuance of an Interest by the Partnership to a Partner (the "Issuance Items")
shall be allocated among the Partners so that, to the extent possible, the net
amount of such Issuance Items, together with all other allocations made to each
Partner pursuant to this Agreement, shall be equal to the net amount that would
have been allocated to each such Partner if the Issuance Items had not been
realized.

          (i) Class A Limited Partner Guaranteed Payment. [Confidential material
has been omitted pursuant to a request for confidential treatment filed with the
Commission under Rule 24b-2(b)and has been filed separately with the
Commission.]

          (j) Depreciation. [Confidential material has been omitted pursuant to
a request for confidential treatment filed with the Commission under Rule 24b-
2(b)and has been filed separately with the Commission.]

          SECTION 4.04. Curative Allocations. (a) The allocations set forth in
Sections 4.03(a) through 4.03(g) and Section 4.05 (the "Regulatory Allocations")
are intended to comply with certain requirements of the Regulations. It is the
intent of the Partners that, to the extent possible, all Regulatory Allocations
shall be offset either with other Regulatory Allocations or with special
allocations of other items of Partnership income, gain, loss, or deduction
pursuant to this Section 4.04. Therefore, notwithstanding any other provision of
this Article IV (other than the Regulatory Allocations), the General Partner
shall make such offsetting special allocations of Partnership income, gain, loss
or deduction as are necessary so that, after such offsetting allocations are
made, the balance in each Partner's Capital Account is, to the extent possible,
equal to the balance such Partner's Capital Account would have had if the
Regulatory Allocations were not included in this Agreement. In making offsetting
allocations under this Section 4.04 at any time, the General Partner shall take
into account future Regulatory Allocations under Sections 4.03(a) and 4.03(b)
that, although not made at such time, are likely to offset other Regulatory
Allocations made under Sections 4.03(e) and 4.03(f) prior to such time.

          (b) The General Partner shall have reasonable discretion, with respect
to each Allocation Year, (i) to apply the provisions of Section 4.04(a) in
whatever order is likely to minimize the economic distortions that might
otherwise result from the Regulatory Allocations and (ii) to divide all
allocations pursuant to Section 4.04(a) among the Partners in a manner that is
likely to minimize such economic distortions.

          SECTION 4.05. Limitation on Losses. The Losses allocated pursuant to
Section 4.02 and the items of Partnership loss or deduction allocated pursuant
to Sections 4.03 and 4.04 shall not exceed the maximum amount of Losses that can
be so allocated without causing any Limited Partner to have an Adjusted Capital
Account Deficit at the last day of any Allocation Year. All Losses in excess of
the
<PAGE>
 
                                       8

limitations set forth in the immediately preceding sentence shall be allocated
to the General Partner.

          SECTION 4.06. Priority of Allocations. (a) The allocations set forth
in this Article IV shall be made in the following manner and order of priority:
[Confidential material has been omitted pursuant to a request for confidential
treatment filed with the Commission under Rule 24b-2(b)and has been filed
separately with the Commission.]

          (b) The Partners and the Partnership agree to treat the Partnership as
a partnership for federal, state and local income tax purposes and to report all
Partnership items and all transactions involving the Partnership or any of the
Interests or other ownership or profit interests therein, whether direct or
indirect (collectively, the "Partnership Matters"), in a manner consistent with
such treatment. Furthermore, the Partners and the Partnership agree to report
all Partnership Matters for federal, state and local income tax purposes
consistently with the treatment provided in this Agreement or, if no such
treatment is so provided, consistently with the manner in which the Class A
Limited Partner reasonably determines to treat such Partnership Matters. If the
Class A Limited Partner does not notify the Partnership of its treatment of any
Partnership Matter, the Partners and the Partnership shall report such
Partnership Matter consistently with the manner in which the General Partner
reasonably determines to treat such Partnership Matter.

          SECTION 4.07. Other Allocation Rules. (a) Profits, Losses and any
other items of Partnership income, gain, loss or deduction shall be allocated to
the Partners pursuant to this Article IV as of the last day of each Allocation
Year; provided that Profits, Losses and such other items shall also be allocated
at such times as are required under Section 11.08(b) and at such other times as
the Asset Values of the Partnership Property are adjusted in accordance with
Section 4.09 and the definition of "Asset Value" set forth in the Appendix
attached hereto.

          (b) In the case of a Partner whose entire Interest is retired or sold,
the Partnership taxable year shall close with respect to such Partner, and such
Partner's distributive share of all items of Profits, Losses and other items of
Partnership income, gain, loss or deduction shall be determined by using the
interim closing of the books method under Section 706 of the Code and Section
1.706-1(c)(2)(i) of the Regulations. In all other cases in which it is necessary
to determine the Profits, Losses or any other such items allocable to any
period, Profits, Losses or any such other item shall be determined on a daily,
monthly or other basis, as determined by the General Partner using any
permissible method under Section 706 of the Code and the Regulations promulgated
thereunder.

          (c) The Partners are aware of the income tax consequences of the
allocations made under this Article IV, and each Partner hereby agrees to be
bound by the provisions of this Article IV in reporting their shares of
Partnership income and loss for income tax purposes.

          SECTION 4.08. Tax Allocations: Section 704(c) of the Code. (a) In
accordance with Section 704(c) of the Code and the Regulations promulgated
thereunder, income, gain, loss and deduction with respect to any Permitted Asset
contributed to the capital of the Partnership shall, solely for income tax
purposes, be allocated among the Partners so as to take account of any variation
between the adjusted basis of such Permitted Asset to the Partnership for United
States federal income tax purposes and its Initial Asset Value.

          (b) If the Asset Value of any Partnership Property is adjusted
pursuant to clause (ii)
<PAGE>
 
                                       9

of the definition of "Asset Value" set forth in the Appendix attached hereto,
subsequent allocations of income, gain, loss and deduction with respect to such
Partnership Property shall take account of any variation between the adjusted
basis of such Partnership Property for United States federal income tax purposes
and its Asset Value in the same manner as is provided under Section 704(c) of
the Code and the Regulations promulgated thereunder.

          (c) Depreciation recapture arising under Sections 1245 and 1250 of the
Code shall be allocated in accordance with such Sections and the Regulations
promulgated thereunder.

          (d) Any elections or other decisions relating to such allocations
shall be made by the General Partner in any manner that reasonably reflects the
purpose and intention of this Agreement. Allocations pursuant to this Section
4.08 are solely for purposes of federal, state and local taxes and shall not
affect, or in any way be taken into account in computing, any Partner's Capital
Account or share of Profits, Losses, other items of Partnership income, gain,
loss or deduction, or distributions pursuant to any other provision of this
Agreement.

          (e) Except as otherwise provided in this Agreement, all items of
Partnership income, gain, loss and deduction, and any other allocations not
otherwise provided for herein, shall be divided among the Partners in the same
proportions as they share Profits or Losses and items thereof, as the case may
be, for the Allocation Year.

          (f) Subject to any limitations set forth in the Code and the
Regulations promulgated thereunder (including Section 263 of the Code with
respect to the capitalization of certain expenses), the Partners and the
Partnership hereby agree to treat, for federal, state and local income tax
purposes, all Extraordinary Expenses, all payments made to the Class A Limited
Partner for Qualified Investor Costs and all indemnification payments made to
the Class A Limited Partner pursuant to Section 6.05(b), as Code Section 162
ordinary and necessary expenses incurred in connection with the carrying on of a
trade or business.

          SECTION 4.09. Asset Values. For the purpose of determining the balance
in the Capital Account of each Partner on the Closing Date and for purposes of
determining the amount of gain or loss deemed to be realized on a Mark-to-Market
Valuation of any Permitted Asset, the Asset Values of the Permitted Assets of
the Partnership shall be as follows:

          (a) Initial Asset Values. (i) The initial Asset Value of the Terra
     Newco Stock shall be equal to the sum of (A) the aggregate outstanding
     principal amount of the Terra U.K. Loan plus all accrued and unpaid
     interest thereon, if any, (B) the book value of all Investments made by the
     Partnership, directly or indirectly, in the Ammonia Loop and (C) the face
     value of all Liquid Investments of Terra Newco, plus accrued and unpaid
     interest thereon, if any, adjusted for any unamortized premium or discount
     thereon; provided that each of the amounts or values referred to in
     subclause (i)(A), (i)(B) or (i)(C) of this Section 4.09(a) shall be
     adjusted, if necessary, on a pro forma basis for all reasonably anticipated
     income taxes that will be required to be paid by Terra Newco or any
     Subsidiary of Terra Newco on such amount or value at a rate of 35%.

          (ii) The initial Asset Value of the Terra Capital Note, any of the
     Demand Loans and any of the Permitted Securitization Assets shall be equal
     to the aggregate outstanding principal amount thereof plus all accrued and
     unpaid interest thereon, if any.
<PAGE>
 
                                      10

          (iii) The initial Asset Value of the Methanol Plant and all Methanol
     Related Assets shall be determined pursuant to an appraisal conducted by an
     independent valuation firm acceptable to each of the Partners (the "Initial
     Appraiser") pursuant to the Appraisal Guidelines.

          (iv) The initial Asset Value of any of the Liquid Investments shall be
     equal to the face value thereof, plus accrued and unpaid interest thereon,
     if any, adjusted for any unamortized premium or discount.

          (b) Mark-to-Market Valuation. A Mark-to-Market Valuation shall be made
     upon the occurrence of each Mark-to-Market Event, and the Mark-to-Market
     Value of each Permitted Asset comprising part of the Partnership Property
     shall be determined in accordance with the following provisions, except
     that, unless otherwise expressly provided in this Section 4.09(b), the 
     Mark-to-Market Value of any such Permitted Asset shall be made as of the
     applicable Measurement Date:

               (i) The Terra Newco Stock shall be valued at the sum of:
          [Confidential material has been omitted pursuant to a request for
          confidential treatment filed with the Commission under Rule 24b-
          2(b)and has been filed separately with the Commission.]

          provided that each of the amounts or values referred to in subclause
          (i)(A), (i)(B) or (i)(C) of this Section 4.09(b) shall be adjusted, if
          necessary, on a pro forma basis for all reasonably anticipated income
          taxes that will be required to be paid by Terra Newco or any
          Subsidiary of Terra Newco on such amount or value at a rate of 35%;
          and provided further, however, that, if any payment or other material
          default has occurred and is continuing with respect to the certificate
          of incorporation or bylaws of Terra Newco, the Terra U.K. Loan
          Documents or the Ammonia Loop Completion Guarantee, and such default
          shall continue after the applicable grace period, if any, specified
          therein, the value of the Partnership Property described above in this
          Section 4.09(b)(i) with respect to which such payment or other
          material default shall have occurred and be continuing shall be
          determined by an appraisal firm, investment bank or commercial bank of
          national reputation selected by the General Partner with the consent
          of the Class A Limited Partner (which consent shall not be
          unreasonably withheld).

               (ii) The Terra Capital Note, each of the Permitted Securitization
          Assets and each of the Demand Loans shall be valued at the aggregate
          outstanding principal amount thereof plus all accrued and unpaid
          interest thereon to the date of any such Mark-to-Market Valuation;
          provided that if any payment or other material default has occurred
          and is continuing with respect to the Terra Capital Note, any of the
          Permitted Securitization Assets or any of the Demand Loans, and such
          default shall continue after the applicable grace period, if any,
          specified in the Terra Capital Note or the agreements or instruments
          evidencing or setting forth the terms of any such Permitted
          Securitization Asset or Demand Loan, as the case may be, the value of
          the Partnership Property described above in this Section 4.09(b)(ii)
          with respect to which such payment or other material default shall
          have occurred and be continuing shall be determined by an investment
          bank or commercial bank of national reputation selected by the General
<PAGE>
 
                                       11

          Partner with the consent of the Class A Limited Partner (which consent
          shall not be unreasonably withheld).

               (iii) The Methanol Plant and all of the Methanol Related Assets
          will be valued pursuant to an appraisal conducted by the Initial
          Appraiser on or about the date of such Mark-to-Market Valuation, or,
          if the Initial Appraiser is unavailable or unwilling to do such
          appraisal on or about such date, by an Appraiser pursuant to the
          Appraisal Guidelines; provided, however, that any of the Partners may,
          at such Partner's sole expense, independently elect to determine the
          fair market value of the Methanol Plant and all of the Methanol
          Related Assets, in which case such fair market value shall be
          determined by an Alternate Appraiser pursuant to the Appraisal
          Guidelines (and if the fair market value of the Methanol Plant and all
          of the Methanol Related Assets determined by the Alternate Appraiser
          differs by at least 10% (whether higher or lower) from the fair market
          value thereof determined by the Initial Appraiser or the Appraiser, as
          applicable, then the Methanol Plant and all of the Methanol Related
          Assets will be valued at the average of the respective fair market
          values of the Methanol Plant and all of the Methanol Related Assets
          determined by Initial Appraiser or the Appraiser, as applicable, and
          the Alternate Appraiser).

               (iv) Each of the Liquid Investments of the Partnership shall be
          valued at their face value plus all accrued and unpaid interest
          thereon, if any, to the date of any such Mark-to-Market Valuation,
          adjusted for any unamortized premium or discount thereon at such date;
          provided that if any payment or other material default has occurred
          and is continuing with respect to any of the Liquid Investments, the
          value of the Liquid Investment with respect to which such payment or
          other material default shall have occurred and be continuing shall be
          determined by an investment bank or commercial bank of national
          reputation selected by the General Partner with the consent of the
          Class A Limited Partner (which consent shall not be unreasonably
          withheld).

Each of the Partners hereby agrees that any election by such Partner to have the
Ammonia Loop appraised by an Alternate Appraiser pursuant to Section
4.09(b)(i)(B)(2) or the Methanol Plant and the Methanol Related Assets appraised
by an Alternate Appraiser pursuant to Section 4.09(b)(iii) shall be made as
promptly as practicable and that it shall use its reasonable efforts to cause
each such Alternate Appraiser to diligently conduct its appraisal of the Ammonia
Loop or the Methanol Plant and the Methanol Related Assets, as the case may be,
and to complete such appraisal within a reasonable period of time.

          SECTION 5.02. Terra Partners' Second Priority Distribution. The
General Partner shall cause the Partnership to make cash distributions to the
Terra Partners, on each Distribution Date, Ratably until the Terra Partners have
been distributed an amount equal to the remainder, if any, of (a) the Cumulative
Second Priority Return from the Closing Date to such Distribution Date, minus
(b) all cash distributions in respect of the Second Priority Return previously
made to the Terra Partners pursuant to this Section 5.02; provided, however,
that no distribution shall be made under this Section 5.02 on any Distribution

Loans shall be at least equal to the sum of (i) $145,000,000 and (ii) the
aggregate book value of all fixed and capital assets comprising part of the
Partnership Property which have been sold, transferred or otherwise disposed of
at or prior to such Distribution Date (in each case which book value shall be

acquisition of the applicable fixed or capital asset).

[Confidential material has been omitted pursuant to a request for confidential
treatment filed with the Commission under Rule 24b-2(b)and has been filed

          SECTION 5.04. Amounts Withheld. All amounts withheld pursuant to the
Code or any provision of any other federal, state or local law with respect to
any payment, distribution or allocation to the Partnership or the Partners shall
be treated as amounts distributed to the Partners pursuant to this Article V for
all purposes under this Agreement. The General Partner is hereby authorized to
withhold from distributions, or with respect to allocations, to the Partners and
to pay over to any federal, state or local taxation authority or other
governmental authority any amounts required to be so withheld pursuant to the
Code or any provision of any other federal, state or local law, and shall
allocate any such amounts to the Partners with respect to which such amount was
withheld.

          SECTION 5.05. Tax Distributions. Within ten Business Days after the
end of each Fiscal Quarter, the General Partner shall make a good faith estimate
of the First Priority Return and the taxable income for United States federal
income tax purposes of the Partnership for such Fiscal Quarter. If and to the
extent that the General Partner estimates that the amount of taxable income
allocable to the Class A Limited Partner for such Fiscal Quarter exceeds the
First Priority Return allocated to the Class A Limited Partner for such Fiscal
Quarter, the General Partner shall, within two Business Days after making such
estimate, cause the Partnership to make cash distributions to the Class A
Limited Partner in an amount equal to 45% of such excess.

limitations and restrictions set forth in this Agreement (including, without
limitation, those limitations and restrictions set forth in this Article VI),

          SECTION 6.02. Right to Rely on the General Partner. (a) Any Person
dealing with the Partnership may rely (without duty of further inquiry) upon a
certificate signed by any General Partner as to:

          (i) The identity of the General Partner or any Limited Partner;

          (ii) The existence or nonexistence of any fact or facts which
     constitute a condition precedent to acts by the General Partner or which
     are in any other manner germane to the affairs of the Partnership;

          (iii) The Persons who are authorized to execute and deliver any
     agreement, instrument or other document of or on behalf of the Partnership;
     or

          (iv) Any act or failure to act by the Partnership or any other matter
     whatsoever involving the Partnership or any Partner.


          (b) The signature of the General Partner shall be sufficient to convey
title to any of the Partnership Property, and all of the Partners agree that (i)
a copy of this Agreement may be shown to the appropriate Persons in order to
confirm the authority or such signature and (ii) the signature of the General
Partner shall be sufficient to execute any "statement of partnership" or other
documents necessary or appropriate to effectuate any provision of this
Agreement.

          SECTION 6.03. Restrictions on Authority of the General Partner. Except
as otherwise provided in this Agreement, the General Partner shall not have the
authority to, and the General Partner covenants and agrees that it shall not,
without the consent of all the other Partners (which consent shall not be
unreasonably withheld (it being understood and agreed that the failure of the
Class A Limited Partner to obtain the consent of the requisite lenders and, if
applicable, the agent under the Credit Facility to any of the actions set forth
below in this Section 6.03 shall be deemed to be a reasonable basis for the
Class A Limited Partner to withhold any such consent)):

          (a) Take any action that (i) is in contravention of this Agreement or
     (ii) would subject any Limited Partner to liability as a general partner in
     any jurisdiction;

          (b) Engage in any business or activity on behalf of the Partnership
     that is inconsistent with the purposes of the Partnership described in
     Section 2.01;

          (c) Cause or permit the Partnership to voluntarily take any action
     with respect to the Partnership described in clause (a)(iii), (b) or (c) of
     the definition of "Voluntary Bankruptcy" set forth in the Appendix attached
     hereto;

          (d) Cause or permit the Partnership to acquire, by purchase or
     contribution, any property or assets that, at the time of the acquisition
     thereof, (i) does not constitute a Permitted Asset or (ii) is a Permitted
     Asset comprised of a financial asset that is in default;

          (e) Cause or consent to any amendment, modification or waiver of any
     rights or obligations of the Partnership, or cause or give any consent to
     or approval or make any election on behalf of the Partnership, under any of
     the Transaction Documents if any such amendment,
<PAGE>
 
                                      14

     waiver, consent approval or election, either individually or in the
     aggregate, could reasonably be expected to have a material adverse effect
     on the Partnership's rights or materially increase its obligations
     thereunder, including, without limitation, unless such action is immaterial
     and insubstantial in nature and does not adversely affect the Class A
     Limited Partner:

               (i) Cause or consent to any amendment, modification or waiver of
          any provision of the Terra Capital Note or any of the agreements,
          instruments or other documents evidencing or otherwise setting forth
          the terms of any Demand Loan;

               (ii) Cause or permit Terra Newco to consent to any amendment,
          modification or waiver of any provision of any of the Terra U.K. Loan
          Documents or the Ammonia Loop Completion Guarantee; or

               (iii) Cause or consent to any amendment, modification or waiver
          of any provision of the certificate of incorporation or bylaws of
          Terra Newco or BAI;

          (f) Cause or permit the Partnership to change its Fiscal Year, except
     as required under Section 706 of the Code;

          (g) Cause or permit the admission of any Limited Partner to the
     Partnership other than pursuant to Article XI;

          (h) Cause or permit the Partnership to merge or consolidate with or
     into, or sell all or substantially all of the Partnership Property (whether
     in one transaction or a series of transactions) to, any Person;

          (i) Cause or permit the Partnership to issue any additional Interests
     or any other ownership or profit interests therein to any Person other than
     the Interests issued or held by the Partners referred to in the first
     paragraph of this Agreement on the Closing Date (it being understood and
     agreed that the making of any Additional Capital Contribution pursuant to
     Section 3.03 shall not, in and of itself, constitute the issuance of any
     additional Interests or other ownership or profit interests in the
     Partnership); or

          (j) Cause or permit the Partnership to enter into, or to purchase or
     otherwise acquire, any supply or sales contracts in which the Partnership
     has basis for federal income tax purposes.

Notwithstanding the foregoing provisions of this Section 6.03, the General
Partner shall not have the authority to, and the General Partner covenants and
agrees that it shall not, with or without the consent of any or all of the other
Partners, possess Partnership Property, or assign rights in specific Partnership
Property, other than for a purpose of the Partnership described in Section 2.01.

          SECTION 6.04. Duties and Obligations of the General Partner. (a) The
General Partner shall cause the Partnership to conduct its business, operations
and activities in all material respects separate and apart from the business,
operations and activities of any Terra Partner or any of its Affiliates,
including, without limitation, in all material respects (i) segregating all
Partnership Property and not allowing funds or other Partnership Property to be
commingled with the funds or other property or assets
<PAGE>
 
                                      15

of, held by, or registered in the name of, any Terra Partner or any of its
Affiliates, except as and to the extent contemplated in the Services Agreement,
(ii) maintaining books and financial records of the Partnership separate from
the books and financial records of any Terra Partner and its Affiliates, (iii)
observing all procedures and formalities of the Partnership (including, without
limitation, maintaining minutes of Partnership meetings and acting on behalf of
the Partnership only pursuant to the due authorization of the Partners or as
otherwise required under applicable law), (iv) causing the Partnership to pay
its liabilities solely from the Partnership Property and (v) causing the
Partnership to conduct its dealings with third parties in its own name and as a
separate and independent entity, including dealings conducted pursuant to the
Services Agreement.

          (b) The General Partner shall take in its sole discretion all actions
which are necessary or reasonable and appropriate (i) for the continuation of
the Partnership's valid existence as a limited partnership and its qualification
to do business under the laws of the State of Delaware, the State of Texas and
each other jurisdiction in which such existence or qualification is necessary or
appropriate in order to protect the limited liability of the Limited Partners or
to enable the Partnership to conduct the business in which it is engaged or to
perform its obligations under any agreement, instrument or other document to
which it is a party, except where the failure to so exist or qualify, either
individually or in the aggregate, could not reasonably be expected to have a
Material Adverse Effect, and (ii) for the accomplishment of the purposes of the
Partnership described in Section 2.01, including the acquisition, management,
maintenance, preservation and operation of Permitted Assets in accordance with
the provisions of this Agreement and applicable laws. Without limiting any of
the foregoing provisions of this Section 6.04(b), the General Partner shall
cause the Partnership and its Subsidiaries:

          (A) to maintain all licenses and permits necessary to own or lease and
     operate their respective property and assets and to conduct their
     respective businesses and activities in accordance in all material respects
     with all applicable laws, rules, regulations and orders;

          (B) to pay and discharge (1) all taxes, assessments, reassessments,
     levies and other governmental charges imposed upon it or upon its property
     and assets and (2) all lawful claims, that, if unpaid, might by applicable
     law become a Lien upon its property and assets or any part thereof;
     provided, however, that neither the Partnership nor any of its Subsidiaries
     shall be required to pay or discharge any such tax, assessment,
     reassessment, levy, charge or claim the amount, applicability or validity
     of which is being contested in good faith and by proper proceedings and as
     to which appropriate and adequate reserves are being maintained in
     accordance with GAAP, unless and until any Lien resulting therefrom
     attaches to its property or assets and becomes enforceable against its
     other creditors; and

          (C) to maintain insurance (including, without limitation,
     environmental insurance) for the benefit of the Partnership or its
     Subsidiaries for their respective properties, assets and businesses with
     sound and responsible insurance companies and of such types, in such
     amounts and covering such casualties and contingencies as are at least as
     favorable as those usually carried by companies of established reputations
     engaged in similar businesses and owning similar property and assets in the
     same general areas in which the Partnership or the applicable Subsidiary
     thereof operates and, in any case, as may otherwise be required by
     applicable law.

          (c) The General Partner shall devote to the Partnership such time as
in its sole discretion it determines is necessary for the proper performance of
all duties under this Agreement.
<PAGE>
 
                                       16

Certain officers, directors and employees of the General Partner may from time
to time also be officers, directors or employees of one or more of its
Affiliates. The General Partner shall cause its employees to devote as much time
to the management of the Partnership as is necessary in its sole discretion for
the proper conduct of its business and affairs. The General Partner and its
Affiliates shall not be liable to any Limited Partner or any of its Affiliates
for any action taken or omitted to be taken by it in the good faith exercise of
its reasonable business judgment in the management and operation of the
Partnership.

          (d) The General Partner shall cause all distributions or payments to
the Partners (in their capacities as such) pursuant to any provision of this
Agreement to be made no later than 12:00 Noon (New York City time) on the date
of distribution or payment, and, at the time of any such distribution or
payment, the General Partner shall provide to the other Partners a notice
setting forth the nature of the distribution or payment, each of the Sections of
this Agreement pursuant to which such distribution or payment is being made and
the amount being distributed or paid pursuant to each such Section.
[Confidential material has been omitted pursuant to a request for confidential
treatment filed with the Commission under Rule 24b-2(b)and has been filed
separately with the Commission.]

          (j) The General Partner shall cause the Partnership to comply with all
of the terms  of, and perform all of its obligations under, this Agreement.

          SECTION 6.05.  Indemnification of Class A Limited Partner (a) The
Partnership or, solely to the extent of the Partnership Property, its receiver
or its trustee shall indemnify and hold harmless the Class A Limited Partner for
any and all claims, damages, losses, liabilities and expenses of the Partnership
arising out of or relating to events, developments or circumstances occurring
prior to the Closing Date, other than the liabilities and expenses of the
Partnership comprising part of the Original Capital Contributions of the Terra
Partners and set forth on Schedule I hereto. In the case of any investigation,
litigation or proceeding for which the indemnity under this Section 6.05(a)
applies, such indemnity shall be effective whether or not such investigation,
litigation or proceeding is brought by the Class A Limited Partner, any of its
respective directors, stockholders, partners, members or creditors, the
Partnership or any other Partner and whether or not the Partnership or any other
Partner is otherwise a party thereto. The indemnification provided pursuant to
this Section 6.05(a) shall not guarantee the payment of the First Priority
Return, any Class A Limited Partner Guaranteed Payment in lieu thereof, the
return of any of the Capital Contributions of the Class A Limited Partner or the
retirement or purchase of the Interest of the Class A Limited Partner (whether
through the exercise of the Purchase Option or otherwise).

          (b) The Partnership or, solely to the extent of the Partnership
Property, its receiver or its trustee shall, to the extent any state or local
taxes based on or measured by the income of the Partnership or the Partnership
Property are imposed on the Class A Limited Partner or any Class A Beneficial
Owner by any External Taxing Jurisdiction, indemnify and hold harmless the Class
A Limited Partner or such Class A Beneficial Owner for an amount equal to, on an
After-Tax Basis, the excess of such state and local taxes (determined after
taking into account associated deductions) over the amount of any state or local
tax refund, deduction or credit which the Class A Limited Partner or such Class
A Beneficial Owner (or any of its Affiliates) realizes as a result of the
imposition of such state or local taxes by such External Taxing Jurisdiction,
conclusively presuming for purposes of this Section 6.05(b) that any such
beneficial owner is subject to the tax laws of the State of New York.  The Class
A Limited Partner or the Class A Beneficial Owner seeking indemnification under
this Section 6.05(b) shall provide the Partnership with notice of such claim,
which notice shall set forth in reasonable detail the Class A Limited 

<PAGE>
 
                                       17

Partner's or such Class A Beneficial Owner's calculation of the amount of such
claim. In connection with the foregoing provisions of this Section 6.05(b), the
Class A Limited Partner agrees to use its reasonable efforts, and to cause its
affiliates to use their reasonable efforts, to claim and pursue any state or
local tax refund, deduction or credit that would reduce the indemnification
obligations of the Partnership (or its receiver or trustee) hereunder.

          (c) All indemnities provided for in this Section 6.05 shall survive
any transfer of the Interest of the Class A Limited Partner, in whole or in
part, and the indemnities provided for in Section 6.05(b) shall also survive the
liquidation or winding up of the Partnership.

          (d) (i)  If any claim is made by a third party against the Class A
Limited Partner, any Class A Beneficial Owner, the Liquidator or any Affiliate
of any of the foregoing, or any officer, director, agent, employee,
representative, advisor, successor or assign thereof (each, an "Indemnitee"),
with respect to an actual or potential claim, damage, loss, liability or expense
for which any such Person is otherwise entitled to be indemnified under any
provisions of Section 6.05(a), 6.05(b) or 13.07(b), and any such Person wishes
to be indemnified with respect thereto, such Indemnitee shall promptly notify
the appropriate indemnitor as provided in the applicable Section (the
"Indemnitor"), which notice shall set forth in reasonable detail the nature of
the related claim, damage, loss, liability or expense; provided that the failure
of any such Indemnitee to notify the applicable Indemnitor shall not relieve
such Indemnitor from any liability or other obligation which it otherwise may
have to such Person under Section 6.05(a), 6.05(b) or 13.07(c), as applicable,
or otherwise, unless, and then only to the extent that, such failure results in
the forfeiture of rights or defenses and the Indemnitor incurs an increased
indemnification obligation to such Indemnitee under the terms of such applicable
Section on account of such failure.

          (ii) Any Indemnitor may, by notice to the Indemnitee, take control of
all aspects of the investigation and assume the defense of all claims asserted
against such Indemnitee, and may employ counsel of its choice and at its
expense; provided that (A) no Indemnitor may, without the consent of any
Indemnitee, agree to any settlement that requires such Indemnitee to make any
payment that is not indemnified hereunder, or does not grant a full and
unconditional release to such Indemnitee, and, in any event, such Indemnitor may
not in connection with any such investigation, defense or settlement, without
the consent of any Indemnitee, take or refrain from taking any action which
would reasonably be expected to materially impair the indemnification of such
Indemnitee hereunder or would require such Indemnitee to take or refrain from
taking any action or to make any public statement which such Indemnitee
reasonably considers to materially and adversely affect its rights or interests,
and (B) no Indemnitor may take control of any investigation, defense or
settlement which could reasonably be expected to entail a risk of criminal
liability to any Indemnitee.  Upon the request of any Indemnitee, the Indemnitor
shall use its best efforts to keep such Indemnitee reasonably apprised of the
status of those aspects of such investigation and defense controlled by such
Indemnitor and shall provide such information with respect thereto as such
Indemnitee may reasonably request.  The Indemnitee shall cooperate with the
Indemnitor in all reasonable respects with respect thereto.

          (e) No Indemnitor shall be liable to any Indemnitee for the settlement
by such Indemnitee of any pending or threatened investigation, litigation or
proceeding for which such Indemnitee may seek indemnity under Section 6.05(a)
without the prior written consent of such Indemnitor (which consent shall not be
unreasonably withheld or delayed).  In turn, none of the Indemnitors or any of
their respective Affiliates or their respective officers, directors,
stockholders, partners, members, employees, agents, representatives or advisors
shall effect the settlement of any such pending or threatened 
<PAGE>
 
                                      18

investigation, litigation or proceeding unless either (i) such settlement
includes a full and unconditional release and discharge of each Indemnitee
subject to such investigation, litigation or proceeding from all liability and
potential liability on claims that are the subject matter thereof or (ii) each
Indemnitee subject to such investigation, litigation or proceeding shall give
its prior written consent to the settlement thereof (which consent shall not be
unreasonably withheld or delayed).

          SECTION 6.06.  Compensation and Expenses

          (a)  Compensation and Reimbursement.  Except as otherwise provided in
this Section 6.06, neither any Partner nor any Affiliate of any Partner shall
receive any salary, fee or draw from the Partnership for services rendered to or
on behalf of the Partnership or otherwise in its capacity as a Partner, and
neither any Partner nor any Affiliate of any Partner shall be reimbursed by the
Partnership for any expenses incurred by such Partner or Affiliate on behalf of
the Partnership or otherwise in its capacity as a Partner.

          (b) Management Fee; Expenses.  [Confidential material has been omitted
pursuant to a request for confidential treatment filed with the Commission under
Rule 24b-2(b)and has been filed separately with the Commission.]

                           ROLE OF LIMITED PARTNERS

          SECTION 7.01.  Rights or Powers. The Limited Partners shall not have

          (i) Terra U.K. and Ammonia Loop Information.  As promptly as
     practicable and in any event within two Business Days after receipt
     thereof, all financial and other information received by the Partnership
     regarding the Terra U.K. and its property, assets and businesses and BAI
     and the Ammonia Loop pursuant to Section 6.04(i)(ii).

     other information relating to the Partnership or any of its Subsidiaries,
     or the properties, assets, business, operations or activities thereof, as
     any of the Partners may from time to time reasonably request.

          SECTION 9.03.  Tax Matters.  (a)  The General Partner is authorized to
make any and all elections for federal, state and local tax purposes (including,
without limitation, any election, if permitted by applicable law):

          (i) to adjust the basis of Partnership Property pursuant to Sections
     754, 734(b) and 743(b) of the Code, or comparable provisions of state or
     local law, in connection with Transfers of Interests and Partnership
     distributions;

          (ii) with the consent of the Class A Limited Partner, to extend the
     statute of limitations for assessment of tax deficiencies against the
     Partners with respect to adjustments to the Partnership's federal, state or
     local tax returns; and

          (iii)  to the extent provided in Sections 6221 through 6231 of the
     Code, to represent the Partnership and the Partners before taxation
     authorities and other governmental authorities or courts of competent
     jurisdiction in tax matters affecting the Partnership or the Partners in
     their capacities as Partners, and to file any tax returns and execute any
     agreements or other documents relating to or affecting such tax matters,
     including, without limitation, agreements or other documents that bind the
     Partners with respect to such tax matters or otherwise affect the rights of
     the Partnership and the Partners.

The General Partner is specifically authorized to act as the "Tax Matters
Partner" under the Code and in any similar capacity under state or local law (in
such capacity, the "Tax Matters Partner").  Notwithstanding the generality of
the foregoing, the Tax Matters Partner shall make regular and current reports to
the Class A Limited Partner on the status of all representations of the
Partnership and the Partners before taxation authorities and other governmental
authorities and courts of competent jurisdiction.  Furthermore, without the
prior consent of the Class A Limited Partner (which consent shall not be
unreasonably withheld), the Tax Matters Partner may not enter into any agreement
or document which would affect the amount, timing or character of any item of
Profits or Losses allocated to, or otherwise realized by, the Class A Limited
Partner.

          (b) The General Partner shall cause all necessary tax information to
be delivered to each Partner as soon as practicable and in any event not later
than 90 days after the end of each Fiscal Year.  The General Partner shall file
tax returns for the Partnership prepared in accordance with the Code and the
Regulations.  Promptly and in any event no later than 30 days after the filing
or receipt thereof, the General Partner shall furnish to each other Partner all
federal, state and local tax returns filed on behalf of the Partnership and all
written notices received by the Partnership from any taxation authority or other
governmental authority.

          SECTION 9.04.  Confidential Information.  The Class A Limited Partner
shall keep all information furnished to it pursuant to this Article IX

steps to ensure that any other Person to whom the Class A Limited Partner
provides any such information shall keep such information confidential on a
similar basis as is provided in the Confidentiality Agreement executed and
delivered by the Class A Limited Partner.

meeting shall be given to all Partners not less than seven Business Days nor
more than 30 days prior to the date of such meeting. Partners may vote in
person, by proxy or by telephone at such meeting. Whenever the vote or consent
of Partners is permitted or required under this Agreement, such vote or consent
may be given at a meeting of Partners or may be given in accordance with the
procedure prescribed in Section 10.03. Except as otherwise expressly provided in
this Agreement, the unanimous vote of all of the Partners shall be required to
constitute the act of the Partners.

          (b) For the purpose of determining the Partners entitled to vote on,
or to vote at, any meeting of the Partners or any adjournment thereof, the
General Partner or the Limited Partner requesting such meeting may fix, in
advance, a date as the record date for any such determination.  Such date shall
not be less than ten days nor more than 30 days before any such meeting.

          (c) Each Limited Partner may authorize any Person or Persons to act
for it by proxy on all matters in which a Limited Partner is entitled to
participate, including waiving notice of any meeting, or voting or participating
at a meeting.  Every proxy must be signed by the Limited Partner granting such
proxy or its attorney-in-fact.  No proxy shall be valid for more than 11 months
from the date thereof unless otherwise provided in the proxy.  Every proxy shall
be revocable at the pleasure of the Limited Partner executing it.

          (d) Each meeting of the Partners shall be conducted by the General
Partner or such other Person as the General Partner may appoint pursuant to such
rules for the conduct of the meeting as the General Partner or such other Person
deems appropriate.

                            TRANSFERS OF INTERESTS

          SECTION 11.01.  Restriction on Transfers.  Except as otherwise
permitted under this Agreement, no Partner shall pledge or otherwise Transfer
all or any portion of its Interest.

          SECTION 11.02.  Permitted Transfers.  (a)  Terra Partners. Subject to
the conditions set forth in Section 11.03, a Terra Partner may at any time (i)
pledge all or any portion of its Interest to the agent, the lenders and the
other secured parties under the Terra Capital Loan Documents in accordance with
the terms thereof and (ii) otherwise Transfer all or any portion of its Interest
to (A) Terra or a Wholly Owned Subsidiary of Terra or (B) any other Person
approved by all of the other Partners (such consent not to be unreasonably
withheld).

          (b) Class A Limited Partner.  Subject to the conditions set forth in
Section 11.03, the Class A Limited Partner may pledge or otherwise Transfer all
or any portion of its Interest to any Person other than any of the Persons
specified on Schedule 11.02(b) attached hereto with the consent of the General
Partner, which consent shall not be unreasonably withheld or delayed; provided
that the General Partner shall be deemed to be reasonably withholding such
consent to any pledge or other Transfer (other than pursuant to the Credit
Facility) which imposes additional costs on the Partnership or on any of the
Terra Partners or any of their Affiliates.  The General Partner shall have the
right from time to time to supplement Schedule 11.02(b) attached hereto to
include any other Person that it determines in good faith is a competitor of
Terra.

          (c) Consent to Pledge of Interest of Class A Limited Partner.  Each of
the Partners (other than the Class A Limited Partner) hereby acknowledges
notice, and consents to the terms and conditions, of the pledge and security
agreement related to the Credit Facility and the pledge of the Interest of the
Class A Limited Partner and the rights of the Class A Limited Partner under this
Agreement to the security agent and the lenders under the Credit Facility
pursuant to such pledge and security agreement, and hereby further consents and
agrees to any Transfer of such Interest or such rights made as a result of the
exercise by security agent for the Credit Facility of the rights and remedies
afforded to the security agent, the agent and the lenders under, and in
accordance with the terms of, such pledge and security agreement and the other
loan documentation for the Credit Facility (whether as a result of foreclosure
thereon or any other disposition thereof).

          (d) General.  Any Transfer permitted under this Section 11.02 shall be
a "Permitted Transfer" for all purposes of this Agreement.

          SECTION 11.03.  Conditions to Permitted Transfers.  A Transfer shall
only be treated as a Permitted Transfer under Section 11.02 upon the
satisfaction of the following conditions:

          (a) (i) The transferor and transferee shall execute and deliver to the
     Partnership such documents and instruments of conveyance as may be
     necessary or appropriate in the opinion of counsel to the Partnership to
     effect such Transfer and to confirm the agreement of the transferee 
<PAGE>
 
                                      29

     to be bound by the provisions of this Agreement and (ii) unless the
     requirement of this clause (ii) has been waived by the General Partner, the
     transferee shall execute and deliver to the Partnership a confidentiality
     agreement, in substantially the form of Exhibit B attached hereto (a
     "Confidentiality Agreement"). In addition, unless the requirements of this
     sentence have been waived by the General Partner, the Partnership shall be
     reimbursed by the transferor and/or transferee for all costs and expenses
     (including, without limitation, reasonable fees and expenses of counsel)
     that it reasonably incurs in connection with such Transfer.

          (b) The Transfer shall not cause the Partnership to terminate, within
     the meaning of Section 708(b)(1)(B) of the Code, for United States federal
     income tax purposes, and, unless the General Partner has waived the
     requirements of this Section 11.03(b) with respect to a Transfer by any
     Limited Partner, the transferor shall provide the Partnership a favorable
     opinion of counsel or a qualified tax advisor to such effect.  Such counsel
     or qualified tax advisor, as the case may be, and opinion shall be
     reasonably satisfactory to the General Partner, and the General Partner and
     the other Partners shall provide to such counsel or qualified tax advisor
     any information available to the General Partner or such other Partners, as
     the case may be, as is relevant to such opinion.

          (c) The transferor and transferee shall furnish the Partnership with
     the transferee's federal taxpayer identification number, sufficient
     information to determine the transferee's initial tax basis in the
     Interests Transferred and any other information reasonably necessary to
     permit the Partnership to file all required federal and state tax returns
     and other required information statements or returns.  Without limiting the
     generality of the foregoing, the Partnership shall not be required to make
     any distribution otherwise provided for in this Agreement with respect to
     any Transferred Interests until it has received such information.

          (d) Such Transfer shall be exempt from all applicable registration
     requirements and shall not violate any applicable laws regulating the
     Transfer of securities, and, except in the case of a Transfer of Interests
     to another Partner or to a Wholly Owned Subsidiary of the transferor or of
     any other Partner, unless waived by the General Partner, the transferor
     shall provide an opinion of counsel to such effect.  Such counsel and
     opinion shall be reasonably satisfactory to the General Partner.

          (e) Such Transfer shall not cause the Partnership to be deemed to be
     an "investment company" under the Investment Company Act of 1940, as
     amended, and, unless waived by the General Partner, the transferor shall
     provide an opinion of counsel to such effect.  Such counsel and opinion
     shall be reasonably satisfactory to the General Partner, and the General
     Partner and the other Partners shall provide to such counsel any
     information available to the General Partner or to such other Partners, as
     the case may be, as is relevant to such opinion.

          (f) If the transferor is the General Partner, the transferor and
     transferee shall provide the Partnership with an opinion of counsel to the
     effect that such Transfer will not cause the Partnership to become taxable
     as a corporation for federal income tax purposes.  Such counsel and opinion
     shall be reasonably satisfactory to the other Partners.

          (g) If the transferor is the Class A Limited Partner, unless waived by
     the General Partner, the Class A Limited Partner and the transferee of the
     Class A Limited Partner shall 
<PAGE>
 
                                      30

     execute certificates, in substantially the forms of Exhibits C and D
     attached hereto, respectively (the "Transferor Certificate" and the
     "Transferee Certificate", respectively).

          SECTION 11.04.  Prohibited Transfers.  (a)  Any purported Transfer of
Interests that is not a Permitted Transfer shall be null and void and of no
effect whatever; provided that, if the Partnership is required to recognize a
Transfer that is not a Permitted Transfer (or if the General Partner, in its
sole discretion, elects to recognize a Transfer that is not a Permitted
Transfer), the Interest Transferred shall be strictly limited to the
transferor's rights to allocations and distributions as provided under this
Agreement with respect to such Transferred Interests, which allocations and
distributions may be applied (without limiting any other legal or equitable
rights of the Partnership) to satisfy any debts, obligations or liabilities for
damages that the transferor or transferee of such Interests may have to the
Partnership.

          (b) In the case of a Transfer or attempted Transfer that is not a
Permitted Transfer, the parties engaging or attempting to engage in such
Transfer shall indemnify and hold harmless the Partnership and each of the other
Partners from any and all claims, damages, losses, liabilities and expenses that
the Partnership or any such other Partner may incur (including, without
limitation, incremental tax liability and fees and expenses of counsel) as a
result of such Transfer or attempted Transfer and any efforts to enforce the
indemnity granted under this Section 11.04(b).

          SECTION 11.05.  Admission as Substitute Partners.  Subject to the
other provisions of this Article XI, a transferee of Interests may be admitted
to the Partnership as a substitute Partner only upon satisfaction of the
following conditions:

          (a) If such transferee acquired its interest from a Class A Limited
     Partner, the General Partner shall consent to such admission, which consent
     shall not be unreasonably withheld or delayed;

          (b) The Interests with respect to which the transferee is being
     admitted shall be acquired by means of a Permitted Transfer;

          (c) The transferee shall become a party to this Agreement as a Partner
     and shall execute such documents and instruments as the General Partner may
     reasonably request (including, without limitation, amendments to the
     Certificate) as may be necessary or appropriate to confirm such transferee
     as a Partner in the Partnership and the agreement of such transferee to be
     bound by the terms and conditions of this Agreement;

          (d) Unless waived by the General Partner, the transferee shall pay or
     reimburse the Partnership for all reasonable legal, filing and publication
     costs that the Partnership incurs in connection with the admission of the
     transferee as a Partner with respect to the Transferred Interests;

          (e) Unless waived by the General Partner, if the transferee is a
     Person other than an individual, the transferee shall provide the
     Partnership with evidence satisfactory to counsel for the Partnership that
     such transferee has made each of the representations and warranties
     contained in Section 8.02 or 8.03, as applicable, as of the date of the
     Transfer; and

          (f) If the transferee of an Interest is admitted under this Agreement,
     such transferee 
<PAGE>
 
                                      31

     shall be deemed admitted to the Partnership as a substitute Partner
     immediately prior to the Transfer, and with respect to the transferee of a
     General Partner, such transferee shall continue the business of the
     Partnership without dissolution.

          SECTION 11.06.  Rights of Unadmitted Assignees.  (a)  General.  A
Person who acquires one or more Interests but who is not admitted as a
substitute Partner pursuant to Section 11.05 shall be entitled only to
allocations and distributions with respect to such Interests in accordance with
this Agreement, but shall have no right to any information or accounting of the
affairs of the Partnership, shall not be entitled to inspect the books or
records of the Partnership and shall not have any of the rights of a Partner
under the Act or this Agreement.

          (b) General Partners.  A transferee who acquires an Interest from a
General Partner under this Agreement by means of a Transfer that is permitted
under this Article XI, but who is not admitted as a General Partner, shall have
no authority to act for or bind the Partnership or otherwise to be treated as a
General Partner.  Following such a Transfer, the transferor shall not cease to
be a General Partner of the Partnership and shall continue to be a General
Partner until such time as the transferee is admitted as a General Partner.

          (c) Limited Partners.  Following a transfer to a transferee who
acquires an Interest from a Limited Partner under this Agreement by means of a
Transfer that is permitted under this Article XI, but who is not admitted as a
Limited Partner, the transferor shall not cease to be a Limited Partner of the
Partnership and shall continue to be a Limited Partner until such time as the
transferee is admitted as a Limited Partner under this Agreement.

          SECTION 11.07.  Distributions with Respect to Transferred Interests.  
If any Interest is sold, assigned or otherwise Transferred in compliance with
the provisions of this Article XI, all distributions made on or before the date
of such Transfer shall be made to the transferor, and all distributions made
after such date shall be made to the transferee.  Solely for purposes of making
such distributions, the Partnership shall recognize such Transfer not later than
the end of the calendar month during which it is given notice of such Transfer;
provided, however, that if the Partnership is given notice of a Transfer at
least 14 days prior to the Transfer, the Partnership shall recognize such
Transfer as of the date of such Transfer; and provided further, however, that if
the Partnership does not receive a notice stating the date such Interest was
Transferred and such other information as the General Partner may reasonably
require within 30 days after the end of the accounting period during which the
Transfer occurs, all distributions shall be made to the Person who, according to
the books and records of the Partnership, was the owner of the Interest on the
last day of the accounting period during which the Transfer occurs.  Neither the
Partnership nor the General Partner shall incur any liability for making
distributions in accordance with the provisions of this Section 11.07, whether
or not the General Partner or the Partnership has knowledge of any Transfer of
any Interest.

          SECTION 11.08.  Retirement of Partners' Interest in the Partnership.  
[Confidential material has been omitted pursuant to a request for confidential
treatment filed with the Commission under Rule 24b-2(b)and has been filed

                                       32

                                 GENERAL PARTNER

          SECTION 12.01.  Covenant Not to Withdraw, Transfer or Dissolve. 
Except as otherwise permitted by this Agreement, the General Partner hereby
covenants and agrees not to (a) take any action to file a certificate of
dissolution or its equivalent with respect to itself, (b) withdraw or attempt to
withdraw from the Partnership other than as a result of distributions made under
Section 11.08 in retirement of its entire Interest, (c) exercise any power under
the Act to dissolve the Partnership, (d) Transfer all or any portion of its
Interest in the Partnership as a General Partner, except pursuant to the
applicable provisions of Article XI (and only so long as a substitute General
Partner is admitted pursuant to Section 11.05 at or prior to such time) or (e)
petition for judicial dissolution of the Partnership. Furthermore, the General
Partner hereby covenants and agrees to continue to carry out its duties as
General Partner under this Agreement until a substitute General Partner is
admitted pursuant to Section 11.05 or the Partnership is dissolved and
liquidated pursuant to Article XIII.

          SECTION 12.02.  Termination of Status as General Partner.  (a)  A
General Partner shall cease to be a General Partner upon the earliest to occur
of: (i) the retirement of its entire Interest in accordance with Section 11.08;
(ii) the Bankruptcy of the General Partner; (iii) the Transfer of the General
Partner's entire Interest as a General Partner pursuant to Section 11.02 (so
long as a substitute General Partner is admitted pursuant to Section 11.06 at or
prior to such time); (iv) the involuntary Transfer by operation of law of such
General Partner's Interest; (v) the vote of all of the other Partners to approve
a request by such General Partner to withdraw; or (vi) the vote of the Class A
Limited Partner to remove such General Partner after such General Partner has
attempted to make a Transfer of its Interest that is not permitted under Section
11.02. If, at any time, a Person ceases to be a General Partner without having
Transferred its entire Interest as a General Partner, such Person shall be
treated as an unadmitted transferee of an Interest as a result of a Transfer
(other than a Permitted Transfer) pursuant to Section 11.04. If a Person who is
General Partner ceases to be a General Partner for any reason under this
Agreement, such Person shall continue to be liable as a Partner for all debts,
obligations and liabilities of the Partnership existing at the time such Person
ceases to be a General Partner, regardless of whether, at such time, such debts,
obligations or liabilities were known or unknown, actual or contingent, unless
the substitute General Partner therefor has unconditionally agreed to be liable
for all such debts, obligations and liabilities to the same extent as if such
substitute General Partner had itself incurred such debts, obligations and
liabilities. A Person shall not be liable as a General Partner for debts,
obligations or liabilities of the Partnership arising after such Person ceases
to be a General Partner. Any debts, obligations or liabilities to the
Partnership of any Person who ceases to be a General Partner shall be
collectible by any legal means, and the Partnership is authorized, in addition
to any other remedies it may have at law or in equity, to apply any amounts
otherwise distributable or payable by the Partnership to such Person to satisfy
such debts, obligations or liabilities.

          (b) It is the intention of the Partners that the Partnership not
dissolve as a result of the cessation of any General Partner's status as a
General Partner; provided, however, that if it is determined by a court of
competent jurisdiction that the Partnership has dissolved, the provisions of
Section 13.01 shall govern.

          (c) If at the time a Person ceases to be a General Partner, such
Person is also a Limited Partner with respect to Interests other than its
Interest as a General Partner, such cessation shall not affect such Person's
rights and obligations with respect to its Interests as a Limited Partner.

                          DISSOLUTION AND WINDING UP


          SECTION 13.01.  Liquidation.  (a)  Terminating Events.  The 
Partnership shall dissolve and commence winding up and liquidating upon, and
only upon, the occurrence of a Terminating Event.

          (b) Notice Events.  [Confidential material has been omitted pursuant
to a request for confidential treatment filed with the Commission under Rule
24b-2(b)and has been filed separately with the Commission.]

          SECTION 13.02.  Winding Up.  (a)  Upon the occurrence of a Terminating
Event, the Partnership shall continue solely for the purposes of winding up its
affairs in an orderly manner, liquidating its assets and satisfying the claims
of its creditors and Partners, and no Partner shall take any action with respect
to the Partnership that is inconsistent with the winding up of the Partnership's
business and affairs; provided that all covenants of the Partners contained in
this Agreement and all obligations of the Partners provided for in this
Agreement shall continue to be fully binding upon the Partners until such time
as the Partnership Property has been distributed pursuant to this Section 13.02
and the Certificate has been canceled pursuant to the Act. The Liquidator shall
be responsible for overseeing the winding up and dissolution of the Partnership.
The Liquidator shall take full account of the Partnership's liabilities and all
of the Partnership Property and, except as otherwise provided in Section 13.03,
shall, within 90 days of the occurrence of a Terminating Event, cause the
Partnership Property or the proceeds from the sale, lease, transfer or other
disposition thereof (as determined pursuant to Section 13.08), to the extent
sufficient therefor, to be applied and distributed, to the maximum extent
permitted by applicable law and notwithstanding anything in this Agreement to
the contrary, in the following order of priority:

          (i) First, to creditors other than the Terra Partners (including, to
     the extent otherwise permitted by applicable law, the Class A Limited
     Partner to the extent such Partner is a creditor), in satisfaction of all
     of the Partnership's debts and liabilities other than debts and liabilities
     for which reasonable provision for payment has been made and liabilities
     for distributions to Partners under Section 17-601 or 17-604 of the Act;

          (ii) Second, to the Class A Limited Partner [Confidential material has
     been omitted pursuant to a request for confidential treatment filed with
     the Commission under Rule 24b-2(b)and has been filed separately with the
     Commission.];

          (iii)  Third, to the payment and discharge of all of the Partnership's
     debts and liabilities to the Terra Partners, Ratably, to the extent
     adequate provision therefor has not been made; and

          (iv) Fourth, to the Partners in accordance with their positive Capital
     Accounts on the applicable Measurement Date, after giving effect to all
     contributions, distributions and allocations for all periods.

If any payment or distribution made under this Section 13.02 is made in-kind,
the amount of the payment or distribution shall be equal to the Mark-to-Market
Value of the Partnership Property paid or distributed at the time of such
payment or distribution.
<PAGE>
 
                                      34

          (b) No General Partner shall receive any additional compensation for
any services performed pursuant to this Article XIII.

          (c) Each of the Terra Partners understands and hereby agrees that, by
accepting the provisions of this Section 13.02 setting forth the priority of the
distribution of the Partnership Property to be made upon its liquidation, it
expressly waives any right or claim which it might otherwise have as a creditor
of the Partnership under the Act to receive distributions of the Partnership
Property pari passu with the other creditors of the Partnership in connection
with a distribution of the Partnership Property in satisfaction of any liability
of the Partnership, and each of the Terra Partners hereby subordinates any such
right or claim to all such creditors of the Partnership.

          SECTION 13.03.  Restoration of Deficit Capital Accounts; Compliance
with Timing Requirements of Regulations.  (a)  If the Partnership is
"liquidated" within the meaning of Section 1.704-1(b)(2)(ii)(g) of the
Regulations, (i) distributions shall be made pursuant to this Article XIII to
the Partners who have positive balances in their Capital Accounts in compliance
with Section 1.704-1(b)(2)(ii)(b)(2) of the Regulations and (ii) if the General
Partner Capital Account has a deficit balance in its Capital Account (after
giving effect to all contributions, distributions and allocations for all
taxable years, including the taxable year during which such liquidation occurs),
such General Partner shall contribute to the capital of the Partnership the
amount necessary to restore such deficit balance to zero in compliance with
Section 1.704-1(b)(2)(ii)(b)(3) of the Regulations. If any Limited Partner has a
deficit balance in its Capital Account (after giving effect to all
contributions, distributions and allocations for all taxable years, including
the taxable year during which such liquidation occurs), such Limited Partner
shall have no obligation to make any contribution to the capital of the
Partnership with respect to such deficit, and such deficit shall not be
considered a debt owed to the Partnership or to any other Person for any purpose
whatsoever.

          (b) In the discretion of the Liquidator, with the consent of the Class
A Limited Partner, a portion (determined in the manner provided below) of the
distributions that would otherwise be made to the Partners pursuant to this
Article XIII may be:

          (i) Distributed to a trust established for the benefit of the Partners
     solely for the purposes of liquidating Partnership Property, collecting
     amounts owed to the Partnership and paying any contingent or unforeseen
     liabilities or obligations of the Partnership or of the General Partner
     arising out of or in connection with the Partnership.  The property and
     assets of any such trust shall be distributed to the Partners from time to
     time, in the reasonable discretion of the Liquidator, in the same
     proportions (as determined in the manner provided below) as the amount
     distributed to such trust by the Partnership would otherwise have been
     distributed to the Partners pursuant to Section 13.02; or

          (ii) Withheld to provide a reasonable reserve for Partnership debts
     and liabilities (contingent or otherwise) and to allow for the collection
     of the unrealized portion of any installment obligations owed to the
     Partnership; provided that such withheld amounts shall be distributed to
     the Partners as soon as practicable.

The portion of the distributions that would otherwise have been made to each of
the Partners that is instead distributed to a trust pursuant to 
<PAGE>
 
                                      35

Section 13.03(i) or withheld to provide a reserve pursuant to Section 13.03(ii)
shall be determined in the same manner as the expense or deduction would have
been allocated if the Partnership had realized an expense equal to the amount of
such distributions immediately prior to any distributions being made pursuant to
Section 13.02.

          SECTION 13.04. Deemed Contribution and Liquidation. If the Partnership
is liquidated within the meaning of Section 1.704-1(b)(2)(ii)(g) of the
Regulations and no Terminating Event has occurred and is continuing, the
Partnership Property shall not be liquidated, the Partnership's debts and
liabilities shall not be paid or discharged (except to the extent due and
payable in the ordinary course) and the Partnership's affairs shall not be wound
up. Instead, solely for federal income tax purposes, the Partnership shall be
deemed to have contributed the Partnership Property in-kind to a "new
partnership", which shall be deemed to have taken the Partnership Property
subject to all debts and liabilities of the Partnership. Immediately thereafter,
the Partnership shall be deemed to have been liquidated, distributing new
partnership interests to the Partners, all in accordance with their respective
Capital Accounts. The new partnership shall operate in accordance with this
Agreement.

          SECTION 13.05. Rights of Partners. Each Partner shall look solely to
the Partnership Property for the return of its Capital Contribution and, except
as otherwise provided in this Article XIII, shall have no right or power to
demand or receive Partnership Property other than cash from the Partnership.

          SECTION 13.06. Notice of Dissolution. If a Terminating Event has
occurred and is continuing, the General Partner shall, within 30 days
thereafter, provide notice thereof to each of the other Partners and to all
other parties with whom the Partnership regularly conducts business (as
determined in the discretion of the General Partner) and shall publish notice
thereof in a newspaper of general circulation in each place in which the
Partnership regularly conducts business (as determined in the discretion of the
General Partner).

          SECTION 13.07. The Liquidator. (a) Fees. If the Liquidator is a Person
other than a General Partner, the Partnership is authorized to pay a reasonable
fee to the Liquidator for services performed thereby pursuant to this Article
XIII and to reimburse the Liquidator for its reasonable out-of-pocket costs and
expenses incurred in performing those services.

          (b)  Indemnification. Subject to Section 6.05(d), if the Liquidator is
a Person other than a General Partner, the Partnership, or in the event that the
Partnership has terminated, the General Partner, shall indemnify and hold
harmless the Liquidator and each of its officers, directors, agents, employees
representatives and advisors from any and all claims, damages, losses,
liabilities and expenses arising out of or relating to any action taken or
omitted to be taken by the Liquidator or any such officer, director, agent,
employee, representative or advisor in connection with the liquidation of the
Partnership (including reasonable fees and expenses of counsel incurred by the
Liquidator or any such officer, director, agent, employee, representative or
advisor in connection with the defense of any action or proceeding based on any
such action or omission, which fees and expenses of counsel may be paid as
incurred), except to the extent that any such claim, damage, loss, liability or
expense has resulted from the fraud, willful misconduct or gross negligence of
the Liquidator or any such officer, director, agent, employee, representative or
advisor.

          SECTION 13.08. Form of Liquidating Distributions. (a) General. Except
as provided in this Section 13.08, for purposes of making distributions required
by Section 13.02, the Liquidator may
<PAGE>
 
                                      36


determine whether to distribute all or any portion of the Partnership Property
in-kind or to sell, assign, transfer or otherwise dispose of all or any portion
of the Partnership Property and distribute the proceeds therefrom; provided,
however, that the Liquidator (i) shall not distribute Partnership Property other
than cash to the Class A Limited Partner without the consent of the Class A
Limited Partner and (ii) shall be required to reduce the Partnership Property to
cash to the extent necessary to make distributions in cash to the Class A
Limited Partner pursuant to Section 13.02 unless the Class A Limited Partner
otherwise agrees. [Confidential material has been omitted pursuant to a request
for confidential treatment filed with the Commission under Rule 24b-2(b)and has

     General Partner or the Liquidator deem necessary or appropriate to effect
     the liquidation, winding up, dissolution or termination of the Partnership

     under applicable law to be filed on behalf of the Partnership or is deemed
     necessary by the General Partner or the Liquidator to carry out fully the

hereof.

          SECTION 14.02. Nature of Special Power. The power of attorney granted

     existence of a Partner, and shall survive the delivery of an assignment by
     a Partner of all or a portion of its Interest (except that where the

     power of attorney shall survive the delivery of such assignment for the
     sole purpose of enabling any such attorney-in-fact to effect such
     substitution) and shall extend to such Partner's or assignee's successors
     and assigns.

Any Person may from time to time specify a different address by notice to the
Partnership and the other Partners.

          SECTION 15.02.  Binding Effect. Except as otherwise provided in this
Agreement, every covenant, term and provision of this Agreement shall be binding
upon and inure to the benefit of the Partners and their respective successors,
transferees and assigns.

          SECTION 15.03.  Construction. Every covenant, term and provision of
this Agreement shall be construed simply according to its fair meaning and not
strictly for or against any Partner.

          SECTION 15.04.  Headings. Section and other headings contained in this
Agreement are for reference purposes only and are not intended to describe,
interpret, define or limit the scope, extent or intent of this Agreement or any
provision of this Agreement.

          SECTION 15.05.  Severability. Every term and provision of this
Agreement is intended to be severable, and, if any term or provision of this
Agreement is illegal or invalid for any reason whatsoever, such illegality or
invalidity shall not affect the legality or validity of the remainder of this
Agreement. The immediately preceding sentence of this Section 15.05 shall be of
no force or effect if the
<PAGE>
 
                                      39

consequence of enforcing the remainder of this Agreement without such illegal or
invalid term or provision would be to cause any Partner to lose the benefit of
its economic bargain.

          SECTION 15.06.  Governing Law. The laws of the State of Delaware shall
govern the validity of this Agreement, the construction of its terms and the
interpretation of the rights and duties of the Partners.

irrevocably submits to the jurisdiction of any New York state or Delaware state
court or federal court sitting in New York County, New York, or Wilmington,
Delaware in any action or proceeding arising out of this Agreement, (b) agrees
that all claims in such action may be decided in such court, (c) waives, to the
fullest extent it may effectively do so, the defense of an inconvenient forum
and (d) consents to the service of process by mail. A final judgment in any such
action or proceeding shall be conclusive and may be enforced in other
jurisdictions. Nothing herein shall affect the right of any Partner to serve
legal process in any manner permitted by applicable law or affect its right to
bring any action or proceeding in the courts of any jurisdiction.

          SECTION 15.09.  Execution in Counterparts. This Agreement may be
executed in any number of counterparts and by different Partners in separate
counterparts, each of which when so executed shall be deemed to be an original
and all of which taken together shall constitute one and the same agreement.

          SECTION 15.10.  Treatment as Security. The Partnership and the
Partners intend that the Class A Limited Partnership Interest and each of the
other Interests is a "security" governed by Article 8 of the Delaware Uniform
Commercial Code, 6 Del. C. (S)1-101 et seq., within the meaning of (S)8-
102(a)(15) thereof, the transfer of which may be registered upon the books
maintained for such purpose by the Partnership.

          SECTION 15.11.  Waiver of Jury Trial. Each of the Partners hereby
irrevocably waives all right to trial by jury in any action, proceeding or
counterclaim (whether based on contract, tort or otherwise) arising out of or
relating to this Agreement, any other Transaction Document, any documents
delivered pursuant to the terms of this Agreement or any of the other
Transaction Documents, or any of the transactions contemplated hereby or
thereby.

Dear SALUTATION:

     We are pleased to inform you that, as a key employee of Terra Industries
Inc. (the "Corporation") or a Subsidiary thereof, you have been granted, under
the Terra Industries Inc. 1997 Stock Incentive Plan, an Incentive Stock Option
(the "Option"), evidenced by this letter, to purchase up to a total of the
number of Common Shares set forth above at the price per share set forth above
and on the terms and conditions set forth below.  The Option is intended (but
not warranted) to be an incentive stock option within the meaning of section 422
of the Internal Revenue Code.

1.   The Option cannot be exercised unless you sign your name in the space
provided on the copy of this letter enclosed with this letter and deliver it to
the Corporate Secretary of the Corporation, Terra Centre, 600 Fourth Street,
Sioux City, Iowa 51101, before 4:30 p.m. central time on _______________.  If
the Corporate Secretary does not have your properly executed copy of this letter
before such time, then, anything in this letter to the contrary notwithstanding,
this award shall terminate and be of no effect.  Your signing and delivering a
copy of this letter will not commit you to purchase any of the shares that are
subject to the Option, but will evidence your acceptance of the Option upon the
terms and conditions herein stated.

2.   Subject to the provisions of this letter, the Option shall be exercisable,
in whole at any time or in part from time to time, in integral multiples of 100
shares each (to the maximum extent possible), during the period set forth in
this Section 2.

     a.   The Option shall be exercisable with respect to one-third of the
Number of Shares set forth above beginning on the first business day following
the first anniversary of the Date of Grant.

     b.   The Option shall be exercisable with respect to the next one-third of
the Number of Shares set forth above beginning on the first business day
following the second anniversary of the Date of Grant.

     c.   The Option shall be exercisable with respect to the final one-third of
the Number of Shares set forth above beginning on the first business day
following the third anniversary of the Date of Grant.
<PAGE>
 
     d.   The Option shall be exercisable with respect to all of the Number of
Shares set forth above beginning on the day any one of the following occurs: (i)
any person or group of persons acting in concert (other than Minorco, a company
incorporated under the laws of Luxembourg as a societe anonyme, and its
affiliates or a group consisting solely of such persons (the "Minorco
Affiliates")) acquires beneficial ownership (within the meaning of Rule 13d-3 of
the Securities and Exchange Commission promulgated under the Securities Exchange
Act of 1934) of the outstanding securities (the "Voting Shares") of the
Corporation in an amount having, or convertible into securities having, 25% or
more of the ordinary voting power for the election of directors of the
Corporation, provided that this 25% beneficial ownership trigger shall apply
only when the Minorco Affiliates no longer own 50% or more of the Voting Shares;
(ii) during a period of not more than 24 months, a majority of the Board of
Directors of the Corporation ceases to consist of the existing membership or
successors nominated by the existing membership or their similar successors;
(iii) all or substantially all of the individuals and entities who were the
beneficial owners of the Corporation's outstanding securities entitled to vote
do not own more than 60% of such securities in substantially the same
proportions following a shareholder approved reorganization, merger, or
consolidation; or (iv) shareholder approval of either (A) a complete liquidation
or dissolution of the Corporation or (B) a sale or other disposition of all or
substantially all of the assets of the Corporation, or a transaction having a
similar effect.

     e.   The Option shall in all events terminate at the close of business on
the last business day preceding the tenth anniversary of the Date of Grant, but
shall be subject to earlier termination as provided in Section 4 hereof.

3.   The Option shall not be transferable by you otherwise than by will or by
the laws of descent and distribution. During your lifetime, the Option shall be
exercisable only by you.

4.   If your employment with the Corporation and all Subsidiaries terminates
during the term of this agreement, the Option shall automatically terminate and
cease to be exercisable, except the term shall be extended (subject to Section
2e) as follows:

     a.   If your employment terminates by reason of your death, the Option
shall terminate and cease to be exercisable one year from the date of death.

     b.   If your employment terminates by reason of Total Disability or
Retirement, the Option shall terminate and cease to be exercisable three years
from the date of Total Disability or Retirement.

     c.   If your employment terminates on or within two years subsequent to the
circumstances contemplated in Section 2d, the Option shall terminate and cease
to be exercisable three months from the date of such termination.

     d.   Notwithstanding the foregoing, in cases of special circumstances the
Committee may, in its sole discretion when it finds that a waiver would be in
the best interests of the Corporation, extend the term of this Option with
respect to all or a portion of the Number of Shares set forth above for such
period of time as the Committee deems appropriate.
<PAGE>
 
5.   The Corporation shall not be obligated to deliver any shares until they
have been listed (or authorized for listing upon official notice of issuance) on
each stock exchange upon which are listed outstanding shares of the same class
as that of the shares at the time subject to the Option and until there has been
compliance with such laws or regulations as the Corporation may deem applicable.
The Corporation agrees to use its best efforts to effect such listing and
compliance. No fractional shares will be delivered.

6.   For the purposes of this Agreement:  (a) a transfer of your employment from
the Corporation to a Subsidiary or vice versa, or from one Subsidiary to
another, without an intervening period, shall not be deemed a termination of
employment, and (b) if you are granted in writing a leave of absence, you shall
be deemed to have remained in the employment of the Corporation or a Subsidiary
during such leave of absence.

7.   In the event of any merger, consolidation, stock dividend, split-up,
combination or exchange of shares or recapitalization or change in
capitalization, the number or kind of shares that are subject to the Option
immediately prior to such event shall be proportionately and appropriately
adjusted without increase or decrease in the aggregate option price to be paid
therefor upon exercise of the Option.  The determination of the Committee as to
the terms of any such adjustment shall be binding and conclusive upon you and
any other person or persons who are at any time entitled to exercise the Option.

8.   Neither you nor any other person shall have any rights of a stockholder as
to shares under the Option until, after proper exercise of the Option, such
shares shall have been recorded on the Corporation's official stockholder
records as having been issued or transferred.

9.   Subject to the terms and conditions of this Agreement, the Option may be
exercised in whole at any time or in part from time to time in integral
multiples of 100 shares each (to the maximum extent possible) by a written
notice on a form approved by the Committee that (i) is signed by the person or
persons exercising the Option, (ii) is delivered to the Corporate Secretary of
the Corporation, Terra Centre, 600 Fourth Street, Sioux City, Iowa 51101 (or at
such other place that the Corporate Secretary may specify by written notice to
you), (iii) signifies election to exercise the Option, (iv) states the number of
shares as to which it is being exercised, and (v) is accompanied by payment in
full of the option price of such shares.  If a properly executed notice of
exercise of the Option is not delivered to and in the hands of the Corporate
Secretary of the Corporation by the applicable expiration date or dates of this
Option, such notice will be deemed null and void and of no effect.  If notice of
exercise of the Option is given by a person or persons other than you, the
Corporation may require as a condition to exercise of the Option the submission
to the Corporation of appropriate proof of the right of such person or persons
to exercise the Option.  Certificates for shares so purchased will be issued and
delivered as soon as practicable.

10.  Payment of the exercise price for shares may be made in cash, by the
delivery of or certification of ownership of Common Shares that have been held
by you for a period of at least six months with a Fair Market Value equal to the
exercise price, or by a combination of cash and such shares that have been held
by you for a period of at least six months.
<PAGE>
 
11.  You agree to notify the Corporate Secretary of the Corporation in the event
the shares acquired by you on exercise of the Option are sold or otherwise
disposed of within one year from the date of exercise or two years from the date
the Option was granted.

     The Option is issued pursuant to the Plan and is subject to its terms.
Capitalized terms used in this letter have the same meanings as defined in the
Plan.  A copy of the Plan is being furnished to you with this letter and also is
available on request from the Corporate Secretary of the Corporation.

                                          Very truly yours,

                                          TERRA INDUSTRIES INC.

Financial Review

Consolidated Results

Net income for 1997 amounted to $206.9 million compared with $134.0 million in
1996 and $159.5 million in 1995 with diluted earnings per share of $2.76, $1.72
and $1.96, respectively, and basic earnings per share of $2.80, $1.74 and $1.98,
respectively. Revenues increased to $2.5 billion in 1997 from $2.3 billion in
1996 and 1995.

The Corporation recorded a pretax gain of $163 million ($1.31 per diluted share,
after-tax) in 1997 to reflect settlement of insurance claims related to the Port
Neal plant rebuild. In 1996, income taxes were reduced $18 million ($0.23 per
share) as a result of a transaction with a Canadian subsidiary of Minorco, the
Corporation's majority shareholder. Net income in 1997 and 1995 was reduced by
$3.0 million ($0.04 per share) and $4.3 million ($0.05 per share), respectively,
due to the write-off of deferred financing fees in connection with the early
retirement of debt.

Financial Comparability and Overview

On December 31, 1997, the Corporation acquired the fertilizer business assets of
Imperial Chemical Industries PLC ("ICI") for approximately $338 million. In
connection with the acquisition, the Corporation issued $125 million of long
term debt and received $225 million to fund a portion of the acquisition through
a partnership that operates the Corporation's methanol plant located at
Beaumont, Texas. The acquisition had no effect on 1997 operations except to
reduce income tax expense by $8 million. See Note 2 to the Consolidated
Financial Statements for pro forma results of operations related to the United
Kingdom acquisition. The Corporation continues to add distribution locations
each year through acquisitions of distributors in its marketing area.

Factors That Affect Operating Results

Factors that may affect the Corporation's future operating results include: the
relative balance of supply and demand for nitrogen fertilizers and methanol, the
number of planted acres - which is impacted by both worldwide demand and
governmental policies - 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 availability and cost of natural gas,
the effect of environmental legislation on demand for the Corporation's
products, the availability of financing sources to fund seasonal working capital
needs, and the potential for interruption to operations due to accident or
natural disaster.
<PAGE>
                                                                               3
Prices for nitrogen products are influenced by the world supply and demand
balance for ammonia and nitrogen-based products. Long-term demand is affected by
population growth and rising living standards that determine food consumption.
Supply is affected by worldwide capacity and the availability of nitrogen
product exports from major producing regions such as the former Soviet Union,
the Middle East and South America. Due to several years of favorable economics
in the industry, capacity additions in the form of new and expanded production
facilities have been undertaken. Consequently, new nitrogen fertilizer supplies
will be coming on-stream and profit margins will be under pressure until
increasing demand is sufficient to absorb new supplies or other marginal
production capacity is shut down.

Methanol is used as a raw material in the production of formaldehyde, methyl
tertiary butyl ether (MTBE), acetic acid and numerous other chemical
derivatives. The price of methanol is highly influenced by the supply and demand
in each of these secondary markets, in particular MTBE, an oxygenate used in
reformulated gasoline and an octane enhancer used in non-reformulated gasoline.
Future demand for MTBE and methanol will depend on the degree to which Clean Air
Act Amendments are implemented and enforced and potential legislation.

Due to the concentration of the Corporation's distribution locations and the
higher quantities 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. Industry analysts expect planted acreage for corn to increase
nearly 2% to 81.5 million acres in 1998. They also expect planted cotton acreage
in the U.S. to decline to 12.1 million acres in 1998 from 13.8 million acres in
1997. Passage of the 1996 Farm Bill (the Federal Agriculture Improvement and
Reform Act of 1996) eliminated annual acreage set-asides and base acreage
restrictions for most crops. This Farm Bill provides farmers more freedom in
making decisions regarding what crops are planted.

Weather can have a significant effect on the Corporation's operations. Weather
conditions that delay or intermittently disrupt field work during the planting
and growing season may result in fewer-than-normal crop inputs being applied
and/or shift plantings to crops with shorter growing seasons. Similar conditions
following harvest may delay or eliminate opportunities to apply fertilizer in
the fall. Weather can also have an adverse effect on crop yields, which lowers
the income of growers and could impair their ability to pay for crop inputs
purchased from the Corporation and its dealer customers.
<PAGE>
                                                                               4
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, crop protection products and seed are typically
manufacturers without the 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 1998, with some major supplier agreements extending into 1999 or longer.

The principal raw material used to produce manufactured nitrogen products and
methanol is natural gas. Natural gas costs in 1997 comprised about 50% of the
total costs and expenses associated with the Nitrogen Products segment and 65%
of the total costs and expenses associated with the Methanol segment. The
Corporation's natural gas procurement policy is to effectively fix or cap the
price of approximately 40% to 80% of its natural gas requirements for a one-year
period and up to 50% of its natural gas requirements for the subsequent two-year
period through various supply contracts, financial derivatives and other forward
pricing techniques. The Corporation believes that there is a sufficient supply
to allow acceptable costs for the foreseeable future and has entered into firm
contracts to minimize the risk of interruption or curtailment of natural gas
supplies during the heating season.

The Corporation's Distribution business segment 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 during which products can be used by customers, the Corporation
builds inventories during the first quarter of the year 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 higher margins. For its current
level of sales, the Corporation requires lines of credit to fund inventory
increases and to support customer credit terms. The Corporation believes that
its credit facilities are adequate for expected sales levels in 1998 and for the
next several years.

The Corporation's manufacturing operations may be subject to significant
interruption if one or more of its facilities were to experience a major
accident or were damaged by severe weather or other natural disaster. The
Corporation currently maintains insurance (including business interruption
insurance) and expects that it will continue to do so in an amount which it
believes is sufficient to allow the Corporation to withstand major damage to any
of its facilities. The Corporation's Port Neal facility experienced such a
casualty on December 13, 1994.

Many of the same factors which affect the Corporation's North American nitrogen
products business also impact the nitrogen products business in the United
Kingdom. Additional factors which affect the United Kingdom operations include
European Community protections against the dumping of cheap fertilizer on the
market, continued deregulation of natural gas and collective bargaining issues.

Derivative Financial Instruments

The Corporation uses derivative financial instruments to manage risk in the
areas of (a) foreign currency fluctuations, (b) changes in natural gas supply
prices and (c) interest rates. See Note 13 to the Consolidated Financial
Statements for information on the use of derivative financial instruments.

RESULTS OF OPERATIONS

1997 COMPARED WITH 1996



Consolidated Results

The Corporation reported net income of $206.9 million, or $2.76 per diluted
share and $2.80 per basic share, on revenues of $2.5 billion for 1997 compared
with net income of $134.0 million, or $1.72 per diluted share and $1.74 per
basic share, on revenues of $2.3 billion in 1996. The Corporation recorded a
gain, net of income taxes, of $1.31 per diluted share in 1997 to reflect
settlement of insurance claims related to the Port Neal plant rebuild (see Note
8 to the Consolidated Financial Statements).

The Corporation classifies its operations into three business segments:
Distribution, Nitrogen Products and Methanol. The Distribution segment includes
sales of products purchased from manufacturers, including the Corporation, and
resold by the Corporation. Distribution revenues are derived primarily from
grower and dealer customers through sales of crop protection products,
fertilizers, seed and services. The Nitrogen Products segment represents only
those operations directly related to the wholesale sales of nitrogen products
produced by the Corporation's ammonia manufacturing and upgrading facilities.
The Methanol segment represents wholesale sales of methanol produced by the
Corporation's two methanol manufacturing facilities.

==============================================================================
</TABLE>

Distribution revenues for 1997 amounted to $1.8 billion compared with $1.6
billion for 1996. New distribution locations generated $101 million of revenues
in 1997 and existing locations generated $106 million of additional revenues
compared with 1996 results. Higher volumes contributed to the increase in
revenue for all product lines due to new locations and increased market share.

Operating income for 1997 for the Distribution segment was $41 million compared
with $24 million for 1996. Expansion of the distribution network contributed $4
million to the operating income increase while existing locations generated an
increase of $13 million. Gross profits increased $49 million due primarily to
the increased sales volume. Selling, general and administrative expenses
increased $33 million in 1997 compared with the 1996 expenses. Additional
equipment, employees and new locations to meet the demands of the 1997 season
contributed to increases in depreciation, operating, maintenance and
compensation expenses. Offsetting these expense increases was a decrease to bad
debt expense of $8 million and a decrease to employee benefits expense of $5
million related to a reduction in retiree medical benefits.

- ------------------------------------------------------------------------------------------------
</TABLE>

Nitrogen Products revenues totaled $621 million for 1997 compared with $654
million for 1996. The $33 million decline in revenues was caused by lower sales
prices for nitrogen solutions and urea offset somewhat by higher
<PAGE>

                                                                               8
 
sales volumes. Lower worldwide demand for urea during 1997, particularly in
China, caused urea prices to fall from prior-year levels. Weather conditions
during the 1997 planting season were more favorable for ammonia application
which kept ammonia prices relatively strong while nitrogen solutions prices
declined. In contrast, 1996 weather conditions forced a late planting season and
favored nitrogen solutions applications resulting in higher prices than in 1997.
Higher 1997 sales volumes were due in part to increased corn acres, which
require more nitrogen than most other crops. Urea sales volumes in 1997
benefitted from expansion and efficiency improvement projects at the Courtright
and Blytheville plants. Additionally, nitrogen solutions sales volumes were
higher in 1997 reflecting the impact of production from the Port Neal plant
which began production of nitrogen solutions in May 1996.

Operating income for the Nitrogen Products segment was $150 million and $255
million for 1997 and 1996, respectively. Lower sales prices, as discussed above,
and 27% higher natural gas costs combined to reduce margins by $103 million in
1997 in comparison with 1996 results. In addition, depreciation expense
increased $7 million during 1997 compared with 1996 due to the rebuilt Port Neal
plant's higher depreciation base. The Corporation's use of financial derivatives
to forward price a portion of its natural gas needs resulted in costs that were
$42 million lower than if bought at 1997 spot prices. The increased sales volume
contributed $16 million to 1997 operating income.

Methanol

Revenues for the Methanol segment amounted to $181 million and $133 million for
1997 and 1996, respectively. Average methanol sales prices were $0.58 per gallon
for 1997 and $0.42 per gallon for 1996 which substantially accounted for the
increase in revenues. The higher methanol prices reflect the tighter methanol
market conditions caused by industry-wide planned and unplanned production
outages and increased worldwide demand. Sales volumes declined 1% in 1997 to 311
million gallons compared with 1996.

Methanol operating income increased $45 million in 1997 compared with 1996
results. The increase is due to higher methanol sales prices which more than
offset a 9% increase in natural gas costs. The Corporation's use of financial
derivatives to forward price a portion of its natural gas needs resulted in cost
savings of $15 million compared with buying at 1997 spot prices.

Other operating expense was $1.3 million in 1997 compared with $2.5 million in
1996. Other expense includes expenses not directly related to individual
business segments, including certain insurance coverages, corporate finance fees
and other costs.

Interest Expense - Net

Net interest expense was $57 million in 1997 compared with $53 million in 1996.
Interest expense increased as a result of additional borrowings used to fund
operations.

Minority Interest

Minority interest, representing primarily third-party unitholder interest in the
earnings of Terra Nitrogen Company, L.P. (TNCLP), was $28 million for 1997
compared with $45 million in 1996. Minority interest declined primarily due to
lower earnings from TNCLP operations.

Income Taxes

Income tax expense was recorded at an effective rate of 37% for 1997 compared
with 32% in 1996. The 1997 tax provision includes an $8 million (2%) benefit
from the recovery of amounts provided in prior years. During 1996, the
Corporation purchased tax benefits from a Canadian subsidiary of Minorco,
resulting in a deferred tax asset for the Corporation which reduced the
effective tax rate by 9%.

Distribution revenues for the year ended December 31, 1996 increased 5.3% to
$1.58 billion from the comparable 1995 period. New locations in 1996 contributed
$69.0 million to the increase in revenues. Same store revenues did not
significantly change in 1996 due to adverse weather conditions, change in mix of
crops, lower insect pressure and the economic condition of some growers.

Operating income for the Distribution segment amounted to $23.9 million for 1996
in comparison with $40.7 million for 1995. Provisions for doubtful accounts
increased $8.1 million in 1996 as a result of two consecutive years of drought
conditions across Southern markets. Growth of the Distribution network to 393
locations from 382 in 1995 increased gross profits by $12.7 million but also
increased selling expenses by $11.7 million. Expense increases resulting from an
expanded sales force and additional equipment at existing locations to meet
demands for services and products in the 1996 season exceeded increases to gross
profits by approximately $8 million.

</TABLE>

Nitrogen Products revenues increased $19.4 million to $654.5 million for 1996 in
comparison with 1995 due to greater sales volumes for ammonia and nitrogen
solutions partly offset by lower sales volumes for urea and lower prices. Sales
volumes increased as a result of the start-up of the Port Neal manufacturing
plant which began producing ammonia in December 1995 and nitrogen solutions in
May 1996.

Nitrogen Products 1996 operating income of $255.3 million was $8.5 million less
than 1995. Earnings attributable to the 1996 start-up of the Port Neal plant
approximated 1995 business interruption proceeds. Price declines of $20.7
million were partially offset by natural gas cost savings of $18.3 million for
1996 compared with 1995. The use of financial derivatives to forward price
natural gas costs more than offset an

approximate 27% increase in the 1996 spot market price of natural gas compared
with 1995. Non-recurring costs of $4.2 million were incurred in 1996 as a result
of staff reductions at the Courtright manufacturing plant.

Methanol

Methanol revenues in 1996 and 1995 totaled $132.5 million and $194.6 million,
respectively. Revenues declined in 1996 as the result of significantly lower
selling prices. Prices fell almost one-third from $0.62 per gallon in 1995 to
$0.42 per gallon in 1996. Sales volumes of 314.7 million gallons for 1996
remained steady in comparison with 1995.

Methanol operating income for 1996 was $18.5 million while 1995 operating income
was $77.1 million. Lower selling prices reduced 1996 Methanol operating income
but were partially offset by lower natural gas costs. Natural gas costs were
lower as the use of financial derivatives to forward price a majority of the
natural gas requirements more than offset an approximate 27% increase in the
spot market price of natural gas for 1996 in comparison with 1995.

Other Operating Expense - Net

Other operating expense was $2.5 million in 1996 compared with $3.9 million in
1995. Other expense includes expenses not directly related to individual
business segments, including certain insurance coverages, corporate finance fees
and other costs.

Interest Expense - Net

Net interest expense of $52.8 million in 1996 approximated 1995 amounts for the
year ended December 31, 1996.

Minority Interest

Minority interest, representing primarily third-party unitholder interest in the
earnings of Terra Nitrogen Company, L.P. (TNCLP), totaled $44.5 million in 1996
compared with $47.2 million in 1995. Minority interest declined due primarily to
the purchase of Senior Preference Units (SPUs) by the Corporation in the second
and third quarters of 1995.

Income Taxes

Income tax expense was recorded at an effective rate of 32.3% for the year ended
December 31, 1996 compared with 41.3% in 1995. During 1996 the Corporation
purchased tax benefits from a Canadian subsidiary of Minorco, resulting in a
deferred tax asset for the Corporation which reduced the effective rate by 9.1%.

Liquidity and Capital Resources


The Corporation's primary uses of funds will be to fund its working capital
requirements, make payments on its indebtedness and other obligations, make
quarterly distributions to minority interests, disburse quarterly dividends on
Common Shares, and make capital expenditures and acquisitions. Its principal
sources of funds will be cash flow from operations and borrowings under
available credit facilities. The Corporation believes that cash from operations
and available financing sources will be sufficient to meet anticipated cash
requirements.

Cash provided by operations in 1997 was $341 million. Working capital balances
decreased $106 million in 1997 due to reductions to inventories and receipt of
refundable income taxes. The ratio of current assets to current liabilities
increased to 1.7 at December 31, 1997 from 1.4 at December 31, 1996. The
Corporation has available a $350 million revolving credit facility for working
capital needs. As of December 31, 1997, $7 million was outstanding under this
facility.

Cash used for investing activities was $371 million in 1997. The purchase of
plant and equipment amounted to $85 million. Cash used for acquisitions ($384
million) is comprised of $338 million to purchase the UK fertilizer business of
ICI (now operated as Terra Nitrogen U.K.) and amounts paid to acquire new
locations for the Corporation's distribution network. In October 1997, the
Corporation announced plans to begin construction of a $57 million capital
project to add an ammonia production loop to the methanol plant in Beaumont,
Texas. The new facility is expected to add 255,000 tons per year of ammonia
capacity without reducing methanol capacity. The project is expected to be
operational in the fourth quarter of 1999. The Corporation expects 1998 capital
expenditures, exclusive of expenditures related to the Beaumont ammonia
production loop and the acquisition of retail distribution locations, to
approximate $70 million consisting of the expansion of existing service centers,
routine replacement of equipment, and efficiency improvements at manufacturing
facilities.

During 1997, the Corporation reached a settlement of $321 million with its
insurance carriers related to the Port Neal casualty property damage and
business interruption claims. As of December 31, 1997, the Corporation had
received $306 million of insurance receipts. The final cash settlement was
received in January 1998.

The Corporation funded the acquisition of Terra Nitrogen U.K. with the issuance
of $125 million of long-term debt, proceeds of $175 million from the
contribution of a $225 million minority preferred limited partnership interest
in the Corporation's Beaumont Methanol, Limited Partnership (BMLP) subsidiary
and available cash. The additional $50 million proceeds contributed through the
BMLP preferred partnership interest will be used to fund the ammonia production
loop at the Beaumont plant. The Corporation prepaid $31 million of long-term
debt in advance of the acquisition financing of Terra Nitrogen U.K.

On April 30, 1996, the Board of Directors of the Corporation authorized the
repurchase of up to 8.5 million Common Shares on the open market and through
privately negotiated transactions over the ensuing fifteen months. The share
repurchase was completed in May 1997 for a total cost of $114.2 million.

On December 17, 1997, the Corporation announced that it is resuming purchases of
common units of Terra Nitrogen Company, L.P. (TNCLP) on the open market and
through privately negotiated transactions. Under an existing authorization of
the Board of Directors dating back to May 1995, the Corporation may acquire up
to 4 million common units of the 6.4 million common units currently held by the
public. There were no purchases under this program in 1997.

During 1997, the Corporation distributed $5.19 per unit, or $33.3 million, to
minority Unitholders, paid a dividend rate of 8.42%, or $1.1 million, to
minority preferred stock shareholders, and paid a dividend of $0.18 per Common
Share which totaled $13.5 million. The cash distribution to minority Unitholders
for the first quarter included $18.5 million from the elimination of the reserve
amount required to support four quarters of minimum quarterly distributions on
the SPUs. Due to the redemption of the SPUs on May 27, 1997, this reserve amount
was no longer required to be maintained.

Pursuant to the provisions of the TNCLP Agreement of Limited Partnership, the
holders of all Senior Preference Units (SPUs) had the right, through March 31,
1997, to convert their SPUs into Common Units on a one-for-one basis. As of
March 31, 1997, approximately 13.3 million of the 13.6 million previously issued
and outstanding SPUs converted to Common Units. The 307,202 SPUs which did not
convert to Common Units were redeemed by TNCLP on May 27, 1997 for $22.105 per
unit, which included a $0.605 distribution per unit for the first quarter of
1997.

Port Neal Holdings Corp. redeemed its $25.0 million non-convertible, preferred
stock on June 30, 1997.

Cash balances at December 31, 1997 were $180.1 million of which $5.4 million is
used to collateralize letters of credit supporting recorded liabilities.

                     RECENTLY ISSUED ACCOUNTING STANDARDS
                     ------------------------------------

In June 1997, the FASB issued SFAS 130, "Reporting Comprehensive Income". SFAS
130 establishes standards for reporting and display of comprehensive income and
its components in a full set of general-purpose financial statements. SFAS 130
is effective for fiscal years beginning after December 15, 1997 and will be
adopted by the Corporation in its 1998 annual financial statements.

In June 1997, the FASB issued SFAS 131, "Disclosures about Segments of an
Enterprise and Related Information". SFAS 131 establishes standards for the way
public enterprises report information about operating segments in annual
financial statements and requires that those enterprises report selected
information about operating segments in interim financial reports issued to
shareholders. It also establishes standards for related disclosures about
products and services, geographic areas and major customers. SFAS 131 is
effective for financial statements for periods beginning after December 15,
1997, and the Corporation will adopt SFAS 131 in its 1998 financial statements.
The Corporation currently complies with most of the provisions of this
Statement, and any additional disclosure required is expected to be minimal.

                               YEAR 2000 ISSUES
                               ----------------

The Year 2000 issue concerns computer programs that use only the last two digits
to identify the year in date fields. If not corrected, many of these computer
applications could fail or create erroneous results on or before January 1,
2000. This issue affects virtually every company.

The Corporation has assigned dedicated resources to address its Year 2000
issues. A significant part, but not all, of the Corporation's computer
environment has been assessed for Year 2000 issues and some remedial actions
have been identified in these assessed areas. The impact of these remedial
actions for areas where an assessment has already been completed is not expected
to be material to the Corporation. Some of these actions have already been
completed at minimal cost.
<PAGE>
 
                                                                              17

The Corporation has initiated an additional organization-wide review of all
possible computing functions, including the process control systems and
instrumentation in the manufacturing facilities. The Corporation is also
assessing Year 2000 issues in relation to its customers, suppliers and other
constituents because the actions of many such third parties may materially
affect the Corporation.

The Corporation anticipates that it will complete all assessment, remediation
and testing efforts for Year 2000 issues in advance of January 1, 2000 with no
material adverse consequences. The costs or consequences of incomplete or
untimely resolution of Year 2000 issues by the Corporation or third parties
could have a material adverse affect on the Corporation.

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. and all majority owned subsidiaries (the Corporation).  All significant
intercompany accounts and transactions have been eliminated.

Foreign exchange:
Results of operations for the foreign subsidiaries 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 ranging from 15 to 20 years for
buildings and 3 to 18 years for plant and equipment.  Maintenance and repair
costs are expensed as incurred.

Excess of costs over net assets of acquired businesses:
The Corporation amortizes costs in excess of fair value of net assets of
businesses acquired using the straight-line method over periods ranging from 15
to 18 years.  Management periodically determines the recoverability of this
asset through an assessment of future operations.

Plant turnaround costs:
Costs related to the periodic scheduled major maintenance of continuous process
production facilities (plant turnarounds) are deferred and charged to product
costs on a straight-line basis during the period to the next scheduled
turnaround, generally two years.

Hedging transactions:
Realized gains and losses from hedging activities and premiums paid for option
contracts are deferred and recognized in the month to which the hedged
transactions relate (see Note 13 - Derivative Financial Instruments).

Stock-based compensation:
The Corporation recognizes compensation costs for stock-based employee
compensation plans based on the difference, if any, between the quoted market
price of the stock and the amount an employee pays to acquire the stock.

Estimates:
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

                                                                              23

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

Per-share results:
Earnings per share are calculated in accordance with SFAS 128, "Earnings Per
Share".  Basic earnings per share data are based on the weighted-average number
of Common Shares outstanding during the period.  Diluted earnings per share data
are based on the weighted-average number of Common Shares outstanding and the
effect of all dilutive potential common shares including stock options,
restricted shares and contingent shares.  All prior periods have been restated
in accordance with SFAS 128.

Recently issued accounting standards:
In June 1997, the FASB issued SFAS 130, "Reporting Comprehensive Income" which
will be effective in 1998.  The Corporation anticipates minimal impact from this
statement.  Also in June 1997, the FASB issued SFAS 131, "Disclosures about
Segments of an Enterprise and Related Information" which will be effective in
1998.  The Corporation currently complies with most provisions of this
Statement, and any additional disclosure required by this Statement is expected
to be minimal.

2.  Acquisitions
On December 31, 1997, a wholly owned subsidiary of the Corporation, Terra
International (Canada) Inc. (Terra Canada) acquired two nitrogen fertilizer
manufacturing plants in the United Kingdom from Imperial Chemical Industries PLC
(ICI) for approximately $338 million.  The plants, located in Billingham and
Severnside, England, produce nitrogen products for sale in the agricultural and
industrial markets in the U.K. and western Europe.  The acquisition has been
accounted for using the purchase method of accounting.  The Corporation funded
the acquisition with $125 million from a five year term loan provided by a bank
group and secured by the assets of Terra Canada, $175 million as part of a
contribution to the Corporation for a $225 million minority preferred limited
interest in its Beaumont Methanol, Limited Partnership subsidiary, and the
balance with available cash.  The purchase price was allocated to the assets
based on estimated fair values at the date of acquisition.  The allocation of
the purchase price to assets acquired is based on preliminary estimates and may
change upon completion of the audit of the opening balance sheet.  The excess of
the purchase price over the fair value of the assets acquired of $24 million
will be amortized on a straight line basis over 18 years which is estimated to
be the average remaining useful life of the manufacturing plants acquired.

Under an ammonium nitrate agreement with ICI, related to the acquisition, which
covers 500,000 metric tons per year, the Corporation has agreed to make payments
based on the market price of ammonium nitrate in connection with the
Corporation's U.K. Business.  The Corporation will be required to make a payment
for each year through 2002 if average ammonium nitrate prices exceed certain
thresholds during any year, subject to maximum payments of (Pounds)58 million
($95.7 million USD) over the term of the agreement.  As a result of making any
such payments, the Corporation will not benefit fully from the U.K. price of
ammonium nitrate over certain thresholds during the term of this agreement.

Operating results subsequent to the date of acquisition will be reflected in the
1998 Consolidated Statements of Income.  The following represents unaudited pro
forma results of operations of the Corporation and the acquired manufacturing
plants as if the acquisition had occurred at the beginning of 1996:

The pro forma operating results were adjusted to include depreciation of the
fair value of capital assets acquired based on estimated useful lives,
amortization of intangibles, interest expense of 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, and is not intended to be a
projection of future operating results or trends.

Identifiable assets in the United Kingdom totaled $358 million as of December
31, 1997.

3. Earnings Per Share

The FASB issued SFAS 128, "Earnings Per Share" (EPS), which is effective for
1997 financial statements.  SFAS 128 requires dual presentation of Basic and
Diluted EPS, as well as restatement of EPS for all periods for which an income
statement or summary of earnings is presented.  The following table provides a
reconciliation between Basic and Diluted EPS.

4.  Accounts Receivable

On August 20, 1996, the Corporation, through Terra Funding Corporation (TFC), a
beneficially owned subsidiary of the Corporation and a limited purpose
corporation, entered into an agreement with a financial institution to sell an
undivided interest in its accounts receivable.  Under the agreement, which
expires August 20, 1999, the Corporation may sell without recourse an undivided
interest in a designated pool of its accounts receivable and receive up to $150
million in proceeds.  Undivided interests in new receivables may be sold as
amounts are collected on previously sold interests.  As of December 31, 1997,
the proceeds of the uncollected balance of accounts receivable

sold totaled $150 million. The Corporation pays a monthly discount fee on the
outstanding amount of the accounts receivable sold which is included in interest
expense in the Consolidated Statements of Income. TFC is a separate legal entity
whose creditors have received security interests in its assets.

8.   Port Neal Casualty

On December 13, 1994, the Corporation's Port Neal facility in Iowa was
extensively damaged as a result of an explosion. Insurance was in force to cover
the Corporation's property damage, business interruption and third-party
liability claims. During 1997, the Corporation reached a settlement with all its
insurance carriers, who agreed to pay the Corporation a total claim fixed at
$321 million. Estimated lost profits under the business interruption policy were
included in income in 1996 and 1995. The rebuild of the Port Neal plant required
the recognition of a new cost basis for the facility, which resulted in
recording a substantial gain in 1997 representing the difference between the
property insurance settlement received on the Port Neal plant and the carrying
value of the facility at the time of the explosion less uninsured expenses. The
Corporation capitalized $249 million related to the rebuild of the Port Neal
manufacturing facility.

The Corporation has a credit agreement to provide revolving credit facilities of
up to $350 million for seasonal working capital needs and other corporate
purposes. There was $7.0 million outstanding at December 31, 1997 which was
classified as long-term debt under the facility. Interest on borrowings under
this line is charged at current market rates.

Under the credit agreement, the Corporation has agreed, among other things, to
maintain certain financial covenants including minimum net worth and interest
coverage ratios and maximum debt to cash flow ratios, and to adhere to certain
limitations on additional debt, capital expenditures, acquisitions, liens, asset
sales, investments, prepayment of subordinated indebtedness, changes in lines of
business and transactions with affiliates. The Corporation's revolving credit
facilities expire December 31, 2000. A commitment fee is charged on the unused
portion of the facilities under the credit agreement, currently 3/8 percent
adjustable based on the Corporation's most recent quarter debt to cash flow
ratio. The credit agreement is secured by the stock of certain principal
subsidiaries of the Corporation as well as substantially all the property of
certain subsidiaries.

Scheduled principal payments for each of the five years 1998 through 2002 are
$9.5 million, $16.5 million, $11.2 million, $8.4 million and $0.6 million,
respectively.

In 1995, the Corporation issued $200 million unsecured 10.5% Senior Notes due in
full June 15, 2005.  The 10.5% Senior Notes are redeemable at the option of the
Corporation, in whole or part, at any time on or after June 15, 2000, initially
at 105.250% of their principal amount, plus accrued interest, declining to
102.625% on or after June 15, 2001, and declining to 100% on or after June 15,
2002.  The 10.5% Senior Notes Indenture contains certain restrictions, including
the issuance of additional debt, payment of dividends, issuance of capital
stock, certain transactions with affiliates, incurrence of liens, sale of
assets, and sale-leaseback transactions.

The 10.75% unsecured Senior Notes are redeemable at the option of the
Corporation, in whole or part, at any time on or after September 30, 1998,
initially at 105.375% of their principal amount, plus accrued interest,
declining to 102.688% on or after September 30, 1999, and declining to 100% on
or after September 30, 2000.   The 10.75% Senior Notes Indenture contains
restrictions similar to those in the 10.5% Senior Notes Indenture.

The Bank Term Notes are secured by substantially all assets of Terra
International (Canada) Inc., a beneficially owned subsidiary of the Corporation.
The Notes require specified annual payments with the balance due January 2,
2003.  The Notes bear interest at a rate based on current market rates,
currently 7.19%.  The Notes include covenants similar to the credit agreement
described in Note 9 - Debt Due Within One Year.

The $30 million unsecured 8.48% Senior Notes and the 8.75% Notes were retired in
December 1997.

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.

================================================================================
</TABLE>

Total rental expense under all leases, including short-term cancelable operating
leases, was approximately $54.3 million, $54.1 million and $46.8 million for the
years ended December 31, 1997, 1996 and 1995, respectively.

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% 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 provided reserves equal to the estimated present
value of these liabilities of $20 million at December 31, 1997.

The Corporation is involved in various legal actions and claims, including
environmental matters, arising from the normal course of business.  It is the
opinion of management that the ultimate resolution of these matters will not
have a material adverse effect on the results of operations, financial position
or net cash flows of the Corporation.

13.  Derivative Financial Instruments

The Corporation manages three categories of risk using derivative financial
instruments:  (a) foreign currency fluctuations, (b) changes in natural gas
supply prices and (c) interest rate fluctuations.  Derivative financial
instruments have credit risk and market risk.

To manage credit risk, the Corporation enters only into derivative transactions
with counter-parties who are currently rated BBB or better or equivalent as
recognized by a national rating agency.  The Corporation will not enter into
transactions with counter-parties if the additional transaction will result in
credit exposure exceeding $20 million. The credit rating of counter-parties may
be modified through guarantees, letters of credit or other credit enhancement
vehicles.

Market risk related to derivative financial instruments should be substantially
offset by changes in the valuation of the underlying items being hedged.

The Corporation classifies a derivative financial instrument as a hedge if all
of the following conditions are met:

1. The item to be hedged must expose the enterprise to currency, interest or
   price risk.
<PAGE>
                                                                              29

2. It must be probable that the results of the hedge position substantially
   offset the effects of currency, interest or price changes on the hedged item
   (e.g., there is a high correlation between the hedge position and changes in
   market value of the hedge item).

3. The derivative financial instrument must be designated as a hedge of the item
   at the inception of the hedge.

A change in the market value of a derivative financial instrument is recognized
as a gain or loss in the period of the change unless the instrument meets the
criteria to qualify as a hedge. If the hedge criteria are met, the accounting
for the derivative financial instrument is related to the accounting for the
hedged item so that changes in the market value of the derivative financial
instrument are recognized in income when the effects of related changes in the
currency rate, interest rate or price of the hedged item are recognized.

A change in the market value of a derivative financial instrument that is a
hedge of a firm commitment is included in the measurement of the transaction
that satisfies the commitment. The Corporation accounts for a change in the
market value of a derivative financial instrument that hedges an anticipated
transaction in the measurement of the subsequent transaction. If a derivative
financial instrument that has been accounted for as a hedge is closed before the
date of the anticipated transaction, the Corporation carries forward the
accumulated change in value of the contract and includes it in the measurement
of the related transaction.

Foreign Currency Fluctuations - The Corporation enters into foreign exchange
forward and option contracts to manage risk associated with foreign currency
exchange rate fluctuations. The contracts are designated as hedges of fixed
obligations and hedges of net foreign currency positions. Contract maturities
are consistent with the settlement dates of items being hedged. Foreign currency
hedges require cash settlement at termination. Gains and losses on these
contracts are deferred and included as a component of the related transaction.
The cash flows related to these transaction gains and losses are reported as
cash flows from operating activities.

A significant portion of the Corporation's Canadian production is sold in the
U.S., or is based on U.S. prices, but many of the production costs are in
Canadian dollars. As a result, the Corporation's earnings will decline when the
Canadian dollar increases in value compared with the U.S. dollar. Consequently,
the Corporation buys Canadian dollars forward or uses derivatives to fix future
exchange rates over a twelve-month period to cover a portion of its estimated
net Canadian dollar requirements which include firm commitments to purchase
natural gas. As of December 31, 1997, the existing forward contracts represented
approximately 15% of anticipated net 1998 Canadian dollar requirements of
approximately $20 million (Cdn).

Natural Gas Prices - United Kingdom Operations - To meet natural gas production
requirements at the Corporation's United Kingdom production facilities, the
Corporation enters into fixed price supply contracts. Accordingly, the
Corporation does not have a hedging program related to its United Kingdom
natural gas needs.

Natural Gas Prices - North American Operations - Natural gas supplies to meet
production requirements at the Corporation's production facilities are purchased
at market prices. Natural gas market prices, as with other commodities, are
volatile and the Corporation effectively fixes prices for a portion of its
natural gas production requirements and inventory through the use of futures
contracts, swaps and options. These contracts reference physical natural gas
prices or appropriate NYMEX futures contract prices. Contract physical prices
are frequently based on the Henry Hub Louisiana price, but natural gas supplies
for the Corporation's six production facilities are physically purchased for
each plant location which often creates a location basis differential between
the contract price and the physical price of natural gas. Accordingly, the use
of financial derivatives may not exactly offset the change in the price of
physical gas. The contracts are traded in months forward and settlement dates
are scheduled to coincide with gas purchases during that future period.

                                                                              30

A swap is a contract between the Corporation and a third party to exchange cash
based on a designated price. Option contracts give the holder the right to
either own or sell a futures or swap contract.  The futures contracts require
maintenance of cash balances generally 10% to 20% of the contract value and
option contracts require initial premium payments ranging from 2% to 5% of
contract value.

The following summarizes open natural gas contracts at December 31, 1997 and
1996:

Annual production requirements are approximately 134 million MMBtu.  Contracts
were in place at December 31, 1997 to cover 68% of 1998 natural gas
requirements, 34% for 1999 and 5% for 2000.

Gains and losses on settlement of these contracts and premium payments on option
contracts are credited or charged to cost of sales in the month in which the
hedged transaction occurs. The risk and reward of outstanding natural gas
positions are directly related to increases or decreases in natural gas prices
in relation to the underlying NYMEX natural gas contract prices.  Realized gains
on closed contracts of $1.6 million relating to future periods have been
deferred and are included in other current assets as of December 31, 1997. Cash
flows related to natural gas hedging are reported as cash flows from operating
activities.

During 1997 and 1996, natural gas hedging activities reduced the Corporation's
natural gas costs by approximately $57.6 million and $74.3 million,
respectively, compared with spot prices.  During 1995, natural gas hedging
activities produced cost increases of approximately $34.5 million compared with
spot prices.

The Corporation has also entered into basis swaps.  Such contracts require
payments to or from the Corporation for the amount, if any, that monthly
published gas prices from the source specified in the contract differ from
prices of NYMEX natural gas futures during a specified period.  There are no
initial cash requirements related to the basis swap agreements.  Gains and
losses on settlement of these contracts are credited or charged to cost of sales
in the month in which the hedged transaction occurs.  Cash flows related to
natural gas basis swaps are reported as cash flows from operating activities.
As of December 31, 1997 and 1996, MMBtu's under such contracts totaled 104.6
million and 16.0 million, respectively.  The unrealized loss on basis swaps at
December 31, 1997 was $2.0 million.

Interest Rate Fluctuations -The Corporation has entered into interest rate swap
agreements to fix the interest rate on a portion of its floating rate debt at an
average rate of approximately 6.09% per annum.  The interest rate swap
agreements are designated as hedges.   At December 31, 1997, the notional amount
of the swap agreement was approximately $300 million.  The differential paid or
received on interest rate swap agreements is recognized as an adjustment to
interest expense.  Cash flows for the interest rate swap agreements are
classified as cash flows from operations.

The following table presents the carrying amounts and estimated fair values of
the Corporation's derivative financial instruments at December 31, 1997 and
1996.  SFAS 107, "Disclosures about Fair Value of Financial Instruments",

The following methods and assumptions were used to estimate the fair value of
each class of financial instrument:

Cash and receivables:  The carrying amounts approximate fair value because of
the short maturity of those instruments.

Equity and other investments:  Investments in untraded companies are valued on
the basis of management's estimates and, when available, comparisons with
similar companies whose shares are publicly traded.

Other assets:  The amounts reported relate to notes receivable obtained from
sale of previous operating assets.  The fair value is estimated based on current
interest rates and repayment terms of the individual notes.

Short-term borrowings:  The carrying amounts approximate fair value because of
the short maturity of these issues.

                                                                              32

Long-term debt:  The fair value of the Corporation's long-term debt is estimated
based on the quoted market price of these or similar issues or by discounting
expected cash flows at the rates currently offered to the Corporation for debt
of the same remaining maturities.

Concentration 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 generally is minimized due to a
large customer base and its geographic dispersion.  Short-term cash investments
are placed in short duration corporate and government debt securities funds with
well capitalized, high quality financial institutions.  By policy, the
Corporation limits the amount of credit exposure in any one type of investment
instrument.

Financial Instruments - At December 31, 1997, the Corporation had letters of
credit outstanding totaling $21.2 million, guaranteeing various insurance and
financing activities.  Short-term investments of $5.4 million at December 31,
1997 and 1996 are restricted to collateralize certain letters of credit.

15.  Stockholders' Equity

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

At December 31, 1997, 1.7 million Common Shares were reserved for issuance upon
award of restricted shares and exercise of employee stock options.

The Corporation has authorized 16,500,000 Trust Shares for issuance.  There was
no activity related to the Trust Shares from December 31, 1994 to December 31,
1997 and no Trust Shares were outstanding at December 31, 1997.
 
Port Neal Holdings Corp. (PNH) was structured to finance and complete the
construction of the Port Neal manufacturing facility and was partially financed
by the issuance of $25 million of non-convertible preferred stock to unrelated
third parties in September 1995.  PNH redeemed the preferred stock on June 30,
1997.

16.  Stock-Based Compensation

The Corporation accounts for its stock-based compensation under the provisions
of Accounting Principles Board Opinion 25, "Accounting for Stock Issued to
Employees", which utilizes the intrinsic value method.  Compensation cost
related to stock-based compensation was $1.2 million, $2.8 million and $1.0
million for the years ended December 31, 1997, 1996 and 1995, respectively.

The Corporation's 1997 Stock Incentive Plan authorized granting key employees
awards in the form of options, rights, performance units or restricted stock.
The aggregate number of Common Shares that may be subject to awards under the
plan may not exceed 3.8 million shares.  There were no outstanding rights or
performance units at December 31, 1997.  The Corporation's 1992 Stock Incentive
Plan authorized granting key employees options, performance units and restricted
shares. No further awards 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.  Stock options and restricted shares vest over specified periods, or in
some cases upon the attainment, prior to a termination date, of pre-established
market price objectives for the Corporation's Common Shares.  The restricted
shares are entitled to normal voting rights and earn dividends as declared
during the performance periods.  At December 31, 1997, 2,960,000 Common Shares
were available for grant under the 1997 Plan.

There were 1,035,000 and 1,052,000 options exercisable at December 31, 1996 and
1995, respectively.

The weighted average fair value of options granted was $3.58 per option for
1997, $4.34 per option for 1996 and $5.08 per option for 1995. The fair value of
options granted was estimated at the date of grant using a Black-Scholes option
pricing model with the following assumptions:

There were 20,000 restricted shares granted during 1997 with a weighted average
fair value of $14.63 per share. There were 376,000 restricted shares granted
during 1996 with a weighted average fair value of $14.40 per share. There were
54,000 restricted shares granted during 1995 with a weighted average fair value
of $12.80 per share.

The pro forma impact on net income and diluted earnings per share of accounting
for stock-based compensation using the fair value method required by SFAS 123,
"Accounting for Stock-Based Compensation" is as follows:

================================================================================
</TABLE>

The pro forma impact only takes into account stock-based compensation grants
since January 1, 1995 and is likely to increase in future years as additional
awards are granted and amortized ratably over the vesting period.

17.  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 were as
follows:

As of December 31, 1997, the Corporation acquired two fertilizer manufacturing
plants in the United Kingdom from Imperial Chemical Industries PLC (ICI).
Employees of these plants became employees of the Corporation. These employees
may elect to transfer their ICI pension to the Corporation's pension plans in
1998. Any transfer will be fully funded by ICI.

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 up to 6% of the employees' pay
base. The cost of the Corporation's matching contribution to the savings plan
totaled $4.6 million in 1997, $4.0 million in 1996 and $3.7 million in 1995.

18.  Post-Retirement Benefits

The Corporation also provides health care benefits for eligible retired
employees of one of its wholly owned subsidiaries. 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 following table indicates the components of the post-retirement medical
benefits obligation included in the Corporation's Consolidated Statements of
Financial Position at December 31:

During 1997, the Corporation amended its retiree medical plan to eliminate
retiree medical benefits for eligible employees who do not retire and elect
participation on or before January 1, 2002. The impact of the amendment was a
$7.0 million decrease to post-retirement medical benefit expense.

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 7.25% in 1997,
7.5% in 1996, and 7.25% in 1995.

There were no NOL carryforwards or alternative minimum tax (AMT) credits at
December 31, 1997.  Remaining unutilized NOL carryforwards were $0.7 million at
December 31, 1996.  AMT credits were $3.0 million at December 31, 1996.  The
Corporation's capital loss carryforwards totaled $5.8 million and $8.6 million
at December 31, 1997 and 1996, respectively.  Capital loss carryforwards that
are not utilized will expire in 2002.  A valuation allowance is provided since
the realization of tax benefits of capital loss carryforwards is not assured.

During 1996, the Corporation, after receiving a favorable ruling from Revenue
Canada, refreshed its tax basis in plant and equipment at its Canadian
subsidiary by entering into a transaction with a Canadian subsidiary of Minorco,
resulting in a deferred tax asset for the Corporation. Minorco, through its
beneficial ownership of Common Shares, owned approximately 57% of the equity of
the Corporation at December 31, 1997. The ultimate realization of the deferred
tax asset will require future taxable income in Canada. The Corporation assessed
its past earnings history and trends and established a valuation allowance of
$5.1 million and $6.1 million, respectively, related to the transaction as of
December 31, 1997 and 1996. The Corporation will continue to review this
valuation allowance and make adjustments as appropriate.

Components of income tax provision (benefit) included in net income other than
from continuing operations are as follows:

21.  Industry Segment Data

The Corporation operates in three principal industry segments - Distribution,
Nitrogen Products and Methanol.  The Distribution segment sells crop inputs -
fertilizer, crop protection products, seed and services - through its farm
service center network.  These inputs include both Terra's own brands and vendor
products from virtually all other agricultural chemical and seed suppliers.
Terra has the largest company-operated farm service center network in North
America.  The Nitrogen Products business produces and distributes ammonia, urea,
nitrogen solutions, and urea feed which are used by farmers to provide crops
with nitrogen, an essential nutrient for plant growth and as a

feed additive for livestock. The Methanol business manufactures and distributes
methanol, which is principally used as a raw material in the production of a
variety of chemical derivatives and in the production of methyl tertiary butyl
ether (MTBE), an oxygenate and an octane enhancer for gasoline. Inter-segment
sales have been recorded at amounts approximating market. Segment revenues and
costs for Distribution, Nitrogen Products and Methanol include inter-segment
transactions. Included in Other are eliminations of inter-segment sales and
unallocated portions of the business. The following summarizes additional

22.  Agreements of Limited Partnerships

Terra Nitrogen Company, L.P. (TNCLP)
In accordance with the Agreement of Limited Partnership of TNCLP, quarterly
distributions to Unitholders and TNC (the General Partner) are made in an amount
equal to 100% of its Available Cash, as defined in the partnership agreement.
During the period which commenced December 4, 1991, and ended on December 31,
1996 (the Preference Period), Senior Preference Units (SPUs) and Common Units
participated equally in distributions after each class of units received its
Minimum Quarterly Distribution, subject to the General Partner's right to
receive cash distributions.  The General Partner receives a combined minimum 2%
of total cash distributions, and as an incentive, the General Partner's
participation increases if cash distributions exceed specified target levels.

Pursuant to the provisions of the TNCLP Agreement of Limited Partnership, the
Preference Period for TNCLP ended on December 31, 1996. Until March 31, 1997,
the holders of all SPUs had the right to elect to convert their SPUs into Common
Units on a one-for-one basis, effective as of December 31, 1996. Any SPUs which
did not convert continued (until redeemed) to be entitled to the Minimum
Quarterly Distribution (MQD) but did not participate with the Common Units in
any additional distributions.

As of March 31, 1997 (the end of the Conversion Period) holders of 13,329,162
SPUs converted their units to Common Units and 307,202 units remained SPUs. The
Common Units began trading on the New York Stock Exchange on April 1, 1997 under
the symbol TNH. Pursuant to the provisions of the Agreement of Limited
Partnership, on May 27, 1997, the Partnership redeemed all SPUs that did not
convert to Common Units. The redemption price was $21.50 per unit. The SPUs
received the MQD of $0.605 per unit for the quarter ended March 31, 1997 in
addition to the redemption price. As a result of the redemption of the SPUs on
May 27, 1997, the

Reserve Amount was no longer required to be maintained. The Reserve Amount of
$18.5 million was distributed out of Available Cash on May 27, 1997 to holders
of the Common Units and to the General Partner.

If at any time less than 25% of the issued and outstanding units are held by
non-affiliates of the General Partner, the Partnership may call, or assign to
the General Partner or its affiliates its right to acquire all such outstanding
units held by non-affiliated person.  The Corporation owned 66% of the Common
Units at December 31, 1997.  TNCLP shall give at least 30 but not more than 60
days notice of its decision to purchase the outstanding units.  The purchase
price per unit will be the greater of (1) the average of any previous twenty
trading days closing prices as of the date five days before the purchase is
announced or (2) the highest price paid by the General Partner or any of its
affiliates for any unit within the 90 days preceding the date the purchase is
announced.

Beaumont Methanol, Limited Partnership (BMLP)
BMLP sold a 42% limited interest for $225 million to Nova Investors LLC (Nova)
an entity not otherwise affiliated with the Corporation, in December 1997.  BMLP
used $175 million of proceeds to partially fund the Terra Nitrogen U.K.
acquisition.  The remaining $50 million will be used to fund construction of the
$57 million ammonia loop at the Beaumont plant.  Terra Methanol Corporation (the
General Partner) and BMC Holdings, Inc. (a limited partner), beneficially owned
subsidiaries of the Corporation, own the 58% majority interest in BMLP.

Nova will receive a first priority return from BMLP approximating LIBOR plus
1.95% on its $225 million investment.  The Corporation will receive a second
priority return that is expected to be 1.5% above the first priority return.
Any earnings in excess of the first and second priority returns, will be
allocable 1% or less to Nova and the remainder to the Corporation.  The first
priority return is cumulative and must be paid in full before any cumulative
second priority returns can be paid.

The partnership will terminate in 2014.  The first priority rate of return is
fixed for three years, whereupon it will be renegotiated among the Corporation
and Nova.  If the partners cannot agree on new rates, the partnership will
terminate or the Corporation may purchase Nova's interest.  At the termination
of the partnership, the assets will be liquidated and the partners will receive
proceeds in accordance with their capital accounts.

The publicly held TNCLP Common Units and the BMLP limited interest are reflected
in the financial statements as minority interest.

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, an
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 financial statements and reporting practices used, as well as
the internal audit function.  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
audited by our independent accountants.  Their audits 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 audits
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 statements of financial position
of Terra Industries Inc. and subsidiaries as of December 31, 1997 and 1996, and
the related consolidated statements of income, cash flows and changes in
stockholders' equity for each of the three years in the period ended December
31, 1997.  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.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards 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. 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 consolidated financial statements present fairly, in all
material respects, the financial position of Terra Industries Inc. and
subsidiaries at December 31, 1997 and 1996, and the results of their operations
and their cash flows for each of the three years in the period ended December
31, 1997 in conformity with generally accepted accounting principles.
