GENERAL

  The Company is a leader in each of its three business segments: (i) the
distribution of crop production products and services, (ii) the manufacture of
nitrogen products and (iii) the manufacture of methanol. The Company owns and
operates the largest independent farm service center network in North America
and is the second largest supplier of crop production products in the United
States. The Company is also the third largest producer of anhydrous ammonia and
one of the two largest producers of 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's distribution network serves the United States and eastern region
of Canada and has grown over the last several years to include, as of December
31, 1995, approximately:

      . 380 farm service centers;

      . 90 fertilizer storage facilities; and

      . 890 affiliated dealer locations.

  The Company's production facilities are comprised of:

      . five nitrogen fertilizer plants, which are located in Oklahoma (the
         "Woodward Facility" and the "Verdigris Facility"), Iowa (the "Port
        Neal Facility"), Ontario, Canada (the "Courtright Facility") and
        Arkansas (the "Blytheville Facility");

      . a methanol production plant, which is located in Texas (the "Beaumont
        Facility") (the Woodward Facility also includes methanol production
        capacity);

      . a crop protection products formulation plant, which is located in
        Arkansas (the "Blytheville Formulation Facility"); and

      . seven additional liquid crop protection product formulation facilities.

  For certain financial information regarding the Company's industry segments

DISTRIBUTION

  The Company's farm service center network is a distribution and marketing
system for a comprehensive line of fertilizers, crop protection products, seeds
and services. The Company's customers are primarily farmers and dealers located
in the midwestern and southern regions of the United States, and the eastern
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
15% of the Company's total crop protection product sales in 1995. As of December
31, 1995, the Riverside/(R)/ line includes approximately 145 products, of which
seven were added in 1995, and 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 by the Company. The Riverside/(R)/ line includes several formulations
produced exclusively by the Company, but does not include proprietary
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 its proprietary brand of corn hybrids, soybean,
wheat and cotton seed varieties, which provide higher margins. These products
represented approximately 14% of the Company's total seed sales in 1995. The
Company also has maintained in the past few years an exclusive retail storefront
marketing and distribution agreement for DEKALB brand seed in the Midwest, which
accounted for approximately 9% of the Company's total 1995 seed sales.

  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 Ag Analytical Services laboratory in
Elida, Ohio to analyze nutrient levels in soil and plant tissue samples.
Analytical results are down-loaded to a mainframe computer located at the
company headquarters in Sioux City, Iowa. These results are readily accessible
to most farm center locations through computer terminal links to the mainframe.
The results of these tests are used by the Company's proprietary CropMaster/R/
program 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 program also provides
"least cost" nutrient blending formula recommendations, makes seed variety
recommendations based on hybrid characteristics and other factors important to
the individual grower, and maintains crop input records for grower customers.
Terra has made a strong commitment to their customers by taking an active role
in "precision agriculture". Precision agriculture utilizes technological
advances which allow growers to view and treat individual, site-specific areas
within their fields versus whole field applications, thus allowing for more
efficient utilization of their input dollars. The Company has invested in
hardware, software and people to meet the demand of Precision in Agriculture/TM/

  In connection with product sales to dealers, the Company provides warehousing
and delivery services. For selected dealer customers, the Company offers a
service package called MarketMaster/TM/. The package includes environmental and
safety audits, business management and agronomic training courses, access to the
Company's Ag Analytical Services

                                       2
<PAGE>
 
laboratory, use of the CropMaster/R/ program and other services. The Company has
504 MarketMaster/TM/ dealer sites as of December 31, 1995.

  Marketing and Distribution. The Company markets its products primarily to
agricultural customers, including both dealers and growers. For 1995,
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 and Southern
Divisions, which include thirteen separate geographical regions. Field personnel
receive regular training through Terra University/(R)/, a series of courses
designed to develop skills in agronomy, management, sales, environmental
responsibility, personal safety and field application. The field salespeople are
supported by the Ag 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.

  Product Formulations. The Company's Blytheville Formulation Facility
formulates dry flowable ("DF") crop protection products and liquid crop
protection products in separate production lines at the same location. DF
formulations are dry, water-dispersible granules that are mixed with water
before application. Because of their dry form, granules have several benefits
compared with liquid formulations including: easier package disposal, easier
cleanup of accidental spills, absence of toxic solvents, no fumes, less weight,
less space required for storage, and no product loss from freezing temperatures
or settling. The Blytheville Formulation Facility is one of thirteen plants in
the U.S. and formulates seven DF products and nine liquid products.
Approximately 65% of the plant's volume in 1995 was attributable to the
Company's own Riverside/(R)/ brand product line. The Company has developed
several DF formulations which are not available from any other producer or
formulator. The Company has also developed DF formulations for a number of
companies that contract all or portions of their production at the Blytheville
Formulation Facility. The Blytheville Formulation Facility is owned 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 are ammonia,
urea and urea ammonium nitrate solution ("UAN"). A significant portion of the
Company's ammonia production is upgraded into other nitrogen fertilizer products
such as urea and UAN.

  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.

                                       3
<PAGE>
 

    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 feed and fertilizer market by converting
ammonia 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 feed supplements.

    UAN Solution. The Company produces UAN at all five of its fertilizer
manufacturing facilities. The Verdigris Facility in Oklahoma is the largest UAN
production facility in the United States. UAN is produced by combining liquid
urea and 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.

    The Company's sales mix of its three principal nitrogen products (including
TNLP on a pro forma basis) for the years ended December 31, 1995, 1994 and 1993
was approximately (based on tons sold):

    Each of the Company's five fertilizer manufacturing facilities is designed
to operate continuously, except for planned biennial shutdowns for maintenance
and installation of 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 for the years
ended December 31, 1995, 1994 and 1993, in the aggregate, was approximately 97%,
95%, and 102%, respectively.

    The Port Neal Facility was the site of a major explosion on December 13,
1994. An investigative committee formed by the Company, which included
independent experts, determined that the explosion was primarily caused by a
defect in the design of the nitric acid sparger in the neutralizer vessel of the
ammonium nitrate plant at the Port Neal Facility. The Company undertook to
repair the facility and began producing ammonia again at the Port Neal Facility
in late December 1995. The Company expects the urea and nitrogen solution
upgrading facilities to be fully operational in the second quarter of 1996.
Property damage and business interruption insurance payments received thus far
have been used to finance, in part, the plant repair and to recover lost
profits. The Company is in discussions with its insurers as to additional
insurance proceeds to which the Company believes it should be entitled. In the
meantime, the Company expects to continue to receive interim progress payments
from its insurers. Terra has invested additional funds for other enhancements
and improvements at the Port Neal Facility.

    The Company owns in fee the real estate on which the Port Neal Facility is
located and has a 75% ownership interest in the related improvements after
transfering the improvements in September 1995 to a subsidiary that was
structured to finance and complete the reconstruction of such facility.

    The Courtright Facility's liquid urea and granulation capacities are
increasing as a result of a plant upgrade project expected to be completed in
1996. Part of the liquid urea upgrade has been operating since late 1995. The
upgrade project will enable the replacement of up to 65,000 tons of annual
ammonia sales with urea and UAN sales. The final project cost is expected to be
approximately $32 million, funded principally through lease financing.

                                       5

    The lease financing agreement for the Courtright Facility expires in April
1997 and requires annual lease payments. The Company has a purchase option
during the term of the lease and at expiration for approximately $72 million
(Cdn). If, at the end of the lease term, the purchase option is not exercised,
the Company must pay to the lessor approximately $61 million (Cdn), subject to
reimbursement based on the proceeds realized upon the sale of the facility by
the lessor.

    Located at the Verdigris Facility are two ammonia plants, two nitric acid
plants and two UAN solution plants and the Port Terminal. The plants are owned
in fee by TNLP, while the Port Terminal is leased from the Tulsa-Rogers County
Port Authority. The leasehold interest is scheduled to expire in April 1999, and
TNLP 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 solution 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 TNLP has the option to extend the lease for twelve successive
terms of five years each at the same rental rate. TNLP 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 TNLP has the
option to renew the lease for four successive periods of five years each at a
nominal annual rental. TNLP also has an option to purchase the property for a
nominal price.

    The Woodward Facility is owned in fee.

    Marketing and Distribution. The Company's principal customers for its
manufactured nitrogen products are large independent dealers, national retail
chains, cooperatives and industrial customers. Industrial customers accounted
for approximately 18% of the Company's total sales of its manufactured nitrogen
products. In 1995, approximately 8% of the Company's fertilizer production was
supplied to its farm service center locations for sale to growers, while the
rest was sold to outside customers. In 1995, no outside customer accounted for
greater than 10% of total manufactured nitrogen fertilizer sales.

    The Company has production facilities and significant storage capacity
throughout the Midwestern U.S. and in other major fertilizer consuming regions
which allow it to be a major supplier of nitrogen fertilizers.

METHANOL

    The Company substantially increased its participation in the methanol
industry in October 1994 with the acquisition of the Beaumont Facility as part
of the acquisition of AMCI. The Company has approximately 320 million gallons of
annual methanol production capacity, representing approximately 15% of the total
United States rated capacity in production at the end of 1995.

    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.

                                       6

    Plants. During the first half of 1994, the Company completed the capital
improvements necessary for optional production of methanol instead of ammonia
for about 30% of the Woodward Facility's ammonia capacity. The design of the
Woodward Facility enabled this conversion to be accomplished for approximately
$16 million of capital spending, which the Company believes is approximately
half the capital cost required to convert most other ammonia plants to methanol
production. The Company has approximately 40 million gallons of annual methanol
capacity at the Woodward Facility. This facility is owned by the Company in fee.

    The Beaumont Facility is the largest methanol production plant in the United
States, with approximately 280 million gallons of annual methanol capacity. The
plant and processing equipment at the Beaumont Facility are owned by BMLP, 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''), BMLP depends on DuPont for access to the
Beaumont Facility. BMLP 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, and the pipelines
used to transport methanol and to obtain natural gas, as well as for certain
utilities and waste water treatment facilities and other essential services.

    Marketing and Distribution. Effective February 2, 1995, BMLP terminated a
marketing services agreement pursuant to which the marketing of methanol from
the Beaumont Facility had been conducted for over a year on an exclusive basis
by Trammochem, a division of Transammonia, Inc. The services provided by
Trammochem included analysis of market conditions for methanol, marketing and
sales on a contract basis and sales on a spot basis, arrangement of
transportation of methanol to customers and customer relations activities. BMLP
retained responsibility for the invoicing and collection of payments from
customers and for loading transportation equipment in accordance with customer
requirements. BMLP paid Trammochem a fee based on the Beaumont Facility's
earnings and sales. Company employees have assumed all functions previously
provided by Trammochem.

    Methanol customers are primarily large chemical or MTBE producers located in
the United States; however, some sales have been made to customers in Central
and South America.

    Methanol Contracts. BMLP has a number of long-term methanol sales contracts,
the most significant of which is with DuPont. In 1995, BMLP sold approximately
60% of its production under such contracts. For 1996, BMLP has contracted to
sell approximately 75% of its production at prices indexed to published sources.
Most of the 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 108
million gallons of methanol through 1997 and 54 million gallons of methanol each
year thereafter until 2001 (representing 39% and 19%, respectively, 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 year's notice.

  Under a methanol hedging agreement, BMLP received a $4 million lump sum
payment in exchange for agreeing to make payments based on the market prices of
methanol and natural gas for the periods October 20, 1994 to December 31, 1995,
calendar year 1996 and calendar year 1997. Payments are generally due five
business days after the end of the applicable period. No payment was due for the
initial period. BMLP will be required to make additional payments under the
methanol hedging agreement if methanol prices are high relative to natural gas
prices as compared with historical price levels. Through the Beaumont Facility
and the Company's other methanol production capabilities, the Company will
benefit from such market price differences at any time it is required to make
payments under such agreement. As a result of making such payments, however,
BMLP will not benefit fully from increases in the price of methanol during the
term of the methanol hedging agreement.

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 $65
million in 1994 and $88 million in 1995 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 has not experienced and does not
expect to experience significant bad debts in its grower finance program.

SEASONALITY AND VOLATILITY

    The agricultural crop production products 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 agricultural crop production products 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, current and projected grain inventories and prices,
and the U.S. government's agricultural policy. Among the governmental policies
that influence the markets for fertilizer are those directly or indirectly
influencing the number of acres planted, the level of grain inventories, the mix
of crops planted and crop prices. Because of these factors which are outside of
the Company's control, there can be no assurance that the relatively high
nitrogen fertilizer price levels achieved in 1995 will continue.

    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.
Methanol prices by mid-1995 returned to historical levels after reaching
uncharacteristically high prices in late 1994 and early 1995. During 1994,
several factors combined to create a tight market and dramatically increased
prices: increased world demand for methanol, a large number of plant shutdowns
and turnarounds in the industry and the phase-in of federally mandated standards
for reformulated gasoline. In part, future demand for methanol will depend 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. The Company estimates that natural gas costs comprised nearly
50% of the total costs and expenses associated with the Company's manufactured
fertilizer operations in 1995. The Company estimates that the purchase and
transportation of natural gas represents over 50% of the costs and expenses
associated with its methanol operations. A significant increase in the price of
natural gas that could not be 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 approximately 40% to 80% of its
natural gas requirements for the upcoming 12 months using supply contracts,
financial derivatives and other forward pricing techniques. Depending on market
conditions, the Company may also effectively fix or cap the price for a portion
of its natural gas requirements for longer periods of time. In the first quarter
of 1995, the Company extended its forward pricing positions for natural gas due
to the decline in natural gas prices

                                       8
<PAGE>
 

and favorable outlook for its manufactured products. The settlement dates are
scheduled to coincide with gas purchases during such future periods. The Company
believes that there is sufficient supply to allow stable costs for the
foreseeable future and has entered into firm contracts to minimize the risk of
interruption or curtailment of natural gas supplies. As of December 31, 1995,
the Company had effectively fixed or capped prices for approximately 78% of its
natural gas requirements for 1996 and 46% for 1997. Liquidation of these open
financial derivatives based on December 31, 1995 market prices would have
resulted in an unrealized gain of $14.9 million. Realized gains on closed
contracts of $11.4 million relating to future periods have been deferred as of
December 31, 1995.

    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 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 90 liquid, dry and anhydrous
ammonia fertilizer terminal storage facilities in numerous states and in
Ontario, Canada. 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.

    Through Terra Express, Inc. ("Terra Express"), a wholly owned truck
transportation subsidiary of Terra International, the Company provides
transportation services to its own facilities and customers as a contract
carrier. Terra Express uses approximately 72 owner-operators and 15 Company
drivers to deliver fertilizer, crop protection products, seed, feed ingredients
and other products to its own facilities and customers. At its manufacturing
facilities, Blytheville Formulation Facility and liquid fertilizer storage
locations, the Company utilizes railcars as the major method of transportation.
The Company leases approximately 1,800 railcars and owns ten nitric acid
railcars.

    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 the widespread pipeline system, and has limited access
to supplies outside the state. 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. Access to
the wharf and the pipeline used at the Beaumont Facility is provided through
agreements with DuPont. 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 Company
maintains facilities for 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 a 70-acre agronomy research station near its
Port Neal Facility for program development and product testing, and routinely
conducts product evaluation and testing on property leased from others and with
growers and universities. The Company also develops DF and other chemical
formulations for its Riverside/(R)/ product line and for basic chemical products
at its Blytheville Formulation Facility.

COMPETITION

    The market for the fertilizer, crop protection products and seed distributed
by the Company is highly competitive. In 1995, 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 in most instances. 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. producers and producers in
other countries, 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. 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.
The relative cost and availability of natural gas and the efficiency of
production facilities are important competitive factors. Significant
determinants of a 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.
In addition, the production and trade of methanol has become increasingly
global, and a number of foreign competitors produce methanol primarily for the
export market.

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 Canada's
operations 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. 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 state laws for all or part of the costs of such investigation and
remediation.

    Terra International 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

                                      10
<PAGE>
 

its farm service centers and terminals, and estimates that the future cost of
complying with these regulations in 1996 and beyond will be approximately $6
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) retains 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 financial condition or results of
operations.

    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 typically applicable to competitors as well. The
Company estimates that the cost of complying with these requirements will total
approximately $11 million to $13 million through 1997.

    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. The Company does not expect its
continued compliance with such regulations to have a material adverse effect on
its earnings or competitive position.


EMPLOYEES

    The Company had approximately 3,500 full-time employees at December 31,
1995, none of whom were covered by a collective bargaining agreement. The
Company also hires temporary employees on a seasonal basis, and hired
approximately 1,600 temporary employees during its spring selling season in
1995.

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 1995.

                 CONDENSED FINANCIAL INFORMATION OF REGISTRANT
                 ---------------------------------------------


                  NOTES TO THE CONDENSED FINANCIAL STATEMENTS
- ------------------------------------------------------------------------------

1.  BASIS OF PRESENTATION

The Condensed Financial Statements include the Registrant only and reflect the
equity method of accounting for its beneficially owned subsidiaries, Terra
Capital, Inc., Terra International, Inc. (TII), Terra Nitrogen Corporation (TNC)
and Beaumont Methanol, Limited Partnership (BMLP). Net income in 1995 and 1994
was reduced by $4.3 million and $2.6 million, or $0.05 and $0.03 per share,
respectively, due to the write-off of deferred financing fees in connection with
the early retirement of debt.

2.  LONG-TERM DEBT

Long-term debt consisted of the following at December 31:

(in thousands)                                        1995        1994

Senior Notes, 10.5%, due 2005                       $200,000    $    ---

- ---------------------------------------------------------------------------
                                                     358,755     158,755
Less current maturities                                  ---         ---
- ---------------------------------------------------------------------------
Total                                               $358,755    $158,755
===========================================================================


In 1995, the Registrant 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
Registrant, 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. Net proceeds of $28.8 million were used
to acquire 974,900 of the outstanding Senior Preference Units (SPUs) of TNCLP.
The remaining net proceeds were used to repay bank term loans.

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. In addition, at any time prior to September 30,
1996, the Registrant may, at its option, redeem up to $61.25 million aggregate
principal amount out of the proceeds of one or more public offerings of equity
securities at a redemption price of 110% of their principal amount, plus accrued
interest. 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 1998.
Total minimum rental payments are: 1996, $3.2 million; 1997, $3.3 million and
1998, $1.7 million. These amounts are not reduced by sublease rentals, which in
1995 were $2.1 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 

                                      S-6
<PAGE>

benefits if the company directly liable is unable to pay them. As a result, if
the purchaser becomes unable to pay its retiree medical obligations assumed
pursuant to the sale, the Registrant may have to pay such amount. The Registrant
has estimated that the present value of liabilities for which it retains
contingent responsibility approximates $9 million at December 31, 1995. In the
event the Registrant would be required to assume this liability, mineral
reserves associated with the sold coal subsidiary would revert to the
Registrant.

The Registrant had letters of credit outstanding totaling $8.9 million at
December 31, 1995 and $9.7 million at December 31, 1994, guaranteeing various
insurance and financing activities. Short-term investments of $8.9 million at
December 31, 1995 and $9.6 million at December 31, 1994 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.

     general corporate purposes of the Company and its Subsidiaries (other than,

          (i) Each Lender severally agrees, on the terms and conditions
     hereinafter set forth, to make advances ("TNLP Advances") to TNLP from time
     to time on any Business Day during the period from the Restatement Date
     until the TNLP Commitment Termination Date in an aggregate amount at any
     one time outstanding not to exceed the amount set forth opposite such
     Lender's name on Schedule 2.01 under the caption "TNLP Commitment" or, if
     such Lender has entered into one or more Assignments and Acceptances, set
     forth for such Lender in the Register as such Lender's "TNLP Commitment"
     (such amount being such Lender's "TNLP Commitment"), and, as to all
     Lenders, in an aggregate amount at any one time outstanding not to exceed
     $25,000,000. On the Restatement Date, all outstanding "TNLP Working Capital
     Advances" of each Lender under the Existing Credit Agreement shall
     automatically, without any action on the part of any Person, be deemed to
     be TNLP Advances hereunder. The aggregate principal amount of the TNLP
     Advances of each Lender as of the Restatement Date shall be the amount set
     forth opposite such Lender's name on Schedule 2.01 under the caption "TNLP
     Advances".

          (ii) The TNLP Advances shall be made by the Lenders ratably according
     to their respective TNLP Commitments.

          (iii) Within the limits of each Lender's TNLP Commitment in effect
     from time to time, TNLP may borrow under this Section 2.01(b) and/or obtain
     the issuance of Letters of Credit under Section 2.13, prepay pursuant to
     Section 2.05(a) and reborrow under this Section 2.01(b); provided, that the
     aggregate outstanding principal amount of TNLP Advances when added to the
     aggregate TNLP Letter of Credit Liability may not at any time exceed the
     aggregate amount of the TNLP Commitments at such time.

          (iv) The proceeds of the TNLP Advances shall be used solely for
     general corporate purposes of TNLP, including, without limitation, to
     finance its ongoing working capital needs and to refinance outstanding
     Debt.

          (c)  Minimum Amounts.  Each Borrowing shall be in an aggregate amount
at least equal to $3,000,000 or an integral multiple of $1,000,000 in excess
thereof.

Lender nor any Issuing Bank shall have any responsibility as to the application
or use of any of the proceeds of any Advance.

          Section 2.02.  Making the Advances.

          (a)  (i) Except as otherwise provided in Section 2.13, each Borrowing
     shall be made on notice, given not later than 11:00 A.M. (New York City
     time) on the Business Day of (or, with respect to a Borrowing of Eurodollar
     Rate Advances, 10:00 A.M. (New York City time) on the second Business Day
     prior to the date of) the proposed Borrowing, by the relevant Borrower to
     the Agent, which shall give to each Lender prompt notice thereof by telex,
     telecopier or cable. Each such notice of a Borrowing (a "Notice of
     Borrowing") shall be by telex, telecopier or cable, confirmed immediately
     in writing, in substantially the form of Exhibit C, specifying therein (1)
     the requested date of such Borrowing, (2) the Facility under which such
     Borrowing is to be made, (3) the requested Type of Advances comprising such
     Borrowing, (4) the requested aggregate amount of such Borrowing and (5) in
     the case of a Borrowing consisting of Eurodollar Rate Advances, the
     requested initial Interest Period for each such Advance.

          (ii)  In the case of a proposed Borrowing comprised of Eurodollar Rate
     Advances, the Agent shall promptly notify each relevant Lender of the
     applicable interest rate under Section 2.06(a)(ii).

          (iii)  Each Lender shall, before 1:00 P.M. (New York City time) on the
     date of each Borrowing after the Restatement Date, make available for the
     account of its Applicable Lending Office to the Agent at the Agent's
     Account, in same day funds, such Lender's ratable portion of such
     Borrowing. After the Agent's receipt of such funds and upon fulfillment of
     the applicable conditions set forth in Article III, the Agent will transfer
     same day funds to the relevant Borrower's Account; provided, that (i) in
     the case of any Terra Borrowing, the Agent shall first make a portion of
     such funds equal to any unreimbursed drawing under any Terra Letter of
     Credit available to each Issuing Bank having issued any such Letter of
     Credit for reimbursement of such drawing, and (ii) in the case of any TNLP
     Borrowing, the Agent shall first make a portion of such funds equal to any
     unreimbursed drawing under any TNLP Letter of Credit available to each
     Issuing Bank having issued any such Letter of Credit for reimbursement of
     such drawing.

          (b) Anything in subsection (a) above to the contrary notwithstanding,
     (i) neither Borrower may select Eurodollar Rate Advances (y) for any
     Borrowing if the aggregate amount of such Borrowing is less than $3,000,000
     or (z) if the obligation of the relevant Lenders to make Eurodollar Rate
     Advances shall then be suspended pursuant to Section 2.08 or


                               Credit Agreement

     2.09, and (ii) Eurodollar Rate Advances may not be outstanding under more
     than 15 separate Interest Periods under either Facility at any one time.

          (c) Each Notice of Borrowing shall be irrevocable and binding on the
     relevant Borrower. In the case of any Borrowing that the related Notice of
     Borrowing specifies is to be comprised of Eurodollar Rate Advances, the
     relevant Borrower shall indemnify each relevant Lender against any loss,
     cost or expense incurred by such Lender as a result of any failure to
     fulfill on or before the date specified in such Notice of Borrowing for
     such Borrowing the applicable conditions set forth in Article III,
     including, without limitation, any loss (including loss of anticipated
     profits), cost or expense incurred by reason of the liquidation or
     reemployment of deposits or other funds acquired by such Lender to fund the
     Advance to be made by such Lender as part of such Borrowing when such
     Advance, as a result of such failure, is not made on such date.

          (d) Unless the Agent shall have received notice from a relevant Lender
     prior to 12:00 Noon (New York City time) on the date of any Borrowing that
     such Lender will not make available to the Agent such Lender's ratable
     portion of such Borrowing, the Agent may assume that such Lender has made
     such portion available to the Agent on the date of such Borrowing in
     accordance with Section 2.02(a) and the Agent may, in reliance upon such
     assumption, make available to the relevant Borrower on such date a
     corresponding amount. If and to the extent that such Lender shall not have
     so made such ratable portion available to the Agent and the Agent shall
     have made available such corresponding amount to the relevant Borrower,
     such Lender and the relevant Borrower severally agree to repay to the Agent
     forthwith on demand such corresponding amount together with interest
     thereon, for each day from the date such amount is made available to the
     relevant Borrower until the date such amount is repaid to the Agent, at (i)
     in the case of the relevant Borrower, the interest rate applicable at such
     time under Section 2.06 to Advances comprising such Borrowing and (ii) in
     the case of such Lender, the Federal Funds Rate. If such Lender shall repay
     to the Agent such corresponding amount, such amount so repaid shall
     constitute such Lender's Advance as part of such Borrowing for purposes of
     this Agreement.

          (e) The failure of any Lender to make the Advance to be made by it as
     part of any Borrowing shall not relieve any other Lender of its obligation,
     if any, hereunder to make its Advance on the date of such Borrowing, but no
     Lender shall be responsible for the failure of any other Lender to

     Borrowing.

          (a)  Terra Advances.  The Company hereby promises to pay to the Agent
for the account of each Lender the full outstanding principal amount of the
Terra Advances of such Lender on the Terra Commitment Termination Date.  In
addition, if following any Terra Commitment Reduction Date the aggregate
principal amount of the Terra Advances, together with the aggregate amount of
all Terra Letter of Credit Liabilities, shall exceed the Terra Commitments, the
Company shall, first, pay Advances and, second, provide cover for Terra Letter
of Credit Liabilities in the manner specified in Section 2.05(d)) in an
aggregate amount equal to such excess.

          (b)  TNLP Advances.  TNLP hereby promises to pay to the Agent for the
account of each Lender the full outstanding principal amount of the TNLP
Advances of such Lender on the TNLP Commitment Termination Date.

2.03 shall be made together with interest accrued to the date of such repayment
on the principal amount repaid.

aggregate amount of $5,000,000 or an integral multiple of $1,000,000 in excess
thereof, and (ii) the aggregate amount of the Commitments under either Facility
shall not be reduced below the Letter of Credit Commitment for such Facility.

(ii) the Agent or the Required Lenders, through the Agent, shall have notified
the Company thereof, each Borrower shall, notwithstanding anything else in this
Agreement to the contrary, pay to the Agent for account of each Lender interest,
during such period, at the applicable Post-Default Rate on any principal of any
Advance made by such Lender to such Borrower, and on any other amount whatsoever
then due and payable by such Borrower hereunder or under the Notes held by such
Lender to or for account of such Lender, such interest to be payable from time
to time on demand.

          Section 2.07.  Fees.

          (a)  Commitment Fee.  Each Borrower hereby promises to pay to the
Agent for the account of each Lender a commitment fee (i) in the case of the
Company, on the average daily Unused Terra Commitment of such Lender and (ii) in
the case of TNLP, on the average daily Unused TNLP Commitment of such Lender, in
each case for the period from the Restatement Date (or from the effective date
specified in the Assignment and Acceptance pursuant to which it became a Lender
in the case of each other Lender other than the Initial Lenders) until the
Commitment Termination Date for the relevant Facility at the Applicable
Commitment Fee Rate, payable in arrears (x) quarterly after the Restatement Date
on each Quarterly Date and (y) on the Commitment Termination Date for the
relevant Facility.  Notwithstanding anything to the contrary contained herein or
in the Existing Credit Agreement, commitment fee accrued under Section 2.07(a)

shall be payable on the first Quarterly Date hereunder following the Restatement
Date.

          (b)  Letter of Credit Commission, Etc.

     account of each Issuing Bank a non-refundable fronting fee of 1/4% per
     annum of the face amount of each Terra Letter of Credit issued by it for
     the period from the date of issuance thereof until such Letter of Credit
     has been drawn in full, expires or is terminated and (B) for the


                               Credit Agreement

     account of each Lender a non-refundable commission on such Lender's Pro
     Rata Share of the average daily aggregate Available Amount of all Terra
     Letters of Credit then outstanding at the Applicable Letter of Credit Fee
     Rate, such fees to be payable in arrears on each Quarterly Date and on the
     Terra Commitment Termination Date and calculated, for any day, after giving
     effect to any payments made under such Letter of Credit on such day.

          (ii)  TNLP hereby promises to pay to the Agent (A) for the account of
     each Issuing Bank a non-refundable fronting fee of 1/4% per annum of the
     face amount of each TNLP Letter of Credit issued by it for the period from
     the date of issuance thereof until such Letter of Credit has been drawn in
     full, expires or is terminated and (B) for the account of each Lender a 
     non-refundable commission on such Lender's Pro Rata Share of the average
     daily aggregate Available Amount of all TNLP Letters of Credit then

     payable quarterly in arrears on each Quarterly Date and on the TNLP

     effect to any payments made under such Letter of Credit on such day.

          (c)  Letter of Credit Expenses.  Each Borrower shall pay to each
Issuing Bank, for its own account, such commission, issuance fees, transfer fees
and other fees and charges in connection with the issuance or administration of
the Letters of Credit issued by it as such Borrower and such Issuing Bank shall
agree; provided, that all fees and other charges payable pursuant to this
Section 2.07(c) shall be the customary amounts charged by such Issuing Bank in
connection with the issuance or administration of similar letters of credit and
the amounts so determined shall be adjusted as necessary to avoid a duplicative
payment hereunder.

          Section 2.08.  Conversion and Continuation of Advances.

          (a)  Optional Conversion.  Each Borrower may on any Business Day, upon
notice given to the Agent not later than 10:00 A.M. (New York City time) on the
second Business Day prior to the date of the proposed Conversion and subject to
the provisions of Sections 2.09 and 2.10, Convert all or any portion of the
Advances of one Type outstanding under any Facility (and, in the case of
Eurodollar Rate Advances, having the same Interest Period); provided, that any
Conversion of Eurodollar Rate Advances into Base Rate Advances shall be made
only on the last day of an Interest Period for such Eurodollar Rate Advances,
any Conversion of Base Rate Advances into Eurodollar Rate Advances shall be in
an amount not less than the minimum amount specified in Section 2.02(b)(i) and
no Conversion of any Advances shall

result in a greater number of separate Interest Periods in respect of Eurodollar
Rate Advances under any Facility than permitted under Section 2.02(b)(ii).  Each
such notice of Conversion shall, within the restrictions specified above,
specify (i) the date of such Conversion, (ii) the aggregate amount, Type and
Facility of the Advances (and, in the case of Eurodollar Rate Advances, the
Interest Period therefor) to be Converted and (iii) if such Conversion is into
Eurodollar Rate Advances, the duration of the initial Interest Period for such
Advances.  Each notice of Conversion shall be irrevocable and binding on the
relevant Borrower.

          (b) Certain Mandatory Conversions.

          (i)  On the date on which the aggregate unpaid principal amount of
     Eurodollar Rate Advances comprising any Borrowing shall be reduced, by
     payment or prepayment or otherwise, to less than $3,000,000 such Advances
     shall automatically Convert into Base Rate Advances.

          (ii)  If a Borrower shall fail to select the duration of any Interest
     Period for any outstanding Eurodollar Rate Advances in accordance with the
     provisions contained in the definition of "Interest Period" in Section 1.01
     and in clause (a) or (c) of this Section 2.08, the Agent will forthwith so
     notify such Borrower and the relevant Lenders, whereupon each such
     Eurodollar Rate Advance will automatically, on the last day of the then
     existing Interest Period therefor, Convert into a Base Rate Advance.

          (iii)  Upon the occurrence and during the continuance of any Event of
     Default and upon notice from the Agent to the Borrowers at the request of
     the Required Lenders, (x) each Eurodollar Rate Advance will automatically,
     on the last day of the then existing Interest Period therefor, Convert into
     a Base Rate Advance and (y) the obligation of the Lenders to make, or to
     Convert Advances into, or to Continue, Eurodollar Rate Advances shall be
     suspended.

          (c)  Continuations.  Each Borrower may, on any Business Day, upon
notice given to the Agent not later than 10:00 A.M. (New York City time) on the
second Business Day prior to the date of the proposed Continuation and subject
to the provisions of Sections 2.09, Continue all or any portion of the
Eurodollar Rate Advances outstanding under a relevant Facility having the same
Interest Period as such Eurodollar Rate Advances; provided, that any such
Continuation shall be made only on the last day of an Interest Period for such
Eurodollar Rate Advances, any Continuation of Eurodollar Rate Advances shall be
in an amount not less than the minimum Borrowing amount specified in Section
2.02(b)(i) and no Continuation of any Eurodollar Rate


                               Credit Agreement

Advances shall result in a greater number of separate Interest Periods in
respect of Eurodollar Rate Advances under any Facility than permitted under
Section 2.02(b)(ii).  Each such notice of Continuation shall, within the
restrictions specified above, specify (i) the date of such Continuation, (ii)
the aggregate amount and Facility of, and the Interest Period for, the Advances
being Continued and (iii) the duration of the initial Interest Period for the
Eurodollar Rate Advances subject to such Continuation.  Each notice of
Continuation shall be irrevocable and binding on the relevant Borrower.

          Section 2.09.  Increased Costs, Illegality, Etc.

          (a)  If, due to either (i) the introduction of or any change in or in
the interpretation of (to the extent any such introduction or change occurs
after the date hereof) any law or regulation or (ii) the compliance with any
guideline or request from any central bank or other governmental authority
adopted or made after the date hereof (whether or not having the force of law),
there shall be any increase in the cost to any Lender of agreeing to make or
making, funding or maintaining Eurodollar Rate Advances under any Facility, then
the relevant Borrower shall from time to time, upon demand by such Lender (with
a copy of such demand to the Agent), pay to the Agent for the account of such
Lender additional amounts sufficient to compensate such Lender for such
increased cost; provided, that, before making any such demand, each Lender
agrees to use reasonable efforts (consistent with its internal policy and legal
and regulatory restrictions) to designate a different Applicable Lending Office
if the making of such a designation would avoid the need for, or reduce the
amount of, such increased cost and would not, in the reasonable judgment of such
Lender, be otherwise disadvantageous to such Lender.  A certificate as to the
amount of such increased cost, submitted to the relevant Borrower by such
Lender, shall be conclusive and binding for all purposes, absent manifest error.

          (b)  If any Lender determines in good faith that compliance with any
law or regulation enacted or introduced after the date hereof or any guideline
or request from any central bank or other governmental authority adopted or made
after the date hereof (whether or not having the force of law) affects or would
affect the amount of capital required or expected to be maintained by such
Lender or any corporation controlling such Lender and that the amount of such
capital is increased by or based upon the existence of such Lender's commitment
to lend hereunder and other commitments of this type or the issuance of the
Letters of Credit (or similar contingent obligations), then, upon demand by such
Lender (with a copy of such demand to the Agent), each Borrower shall pay to the
Agent for the account of such Lender, from time to time as specified by such
Lender, additional amounts sufficient to compensate such Lender in the


                               Credit Agreement
                               ----------------
<PAGE>
 
                                     - 49 -

light of such circumstances, to the extent that such Lender reasonably
determines such increase in capital to be allocable to the existence of such
Lender's commitment to lend hereunder or to the issuance or maintenance of any
Letters of Credit.  A certificate as to such amounts submitted to the relevant
Borrower by such Lender, shall be conclusive and binding for all purposes,
absent manifest error.

          (c)  If, with respect to any Eurodollar Rate Advances, (i) the
Required Lenders reasonably determine and notify the Agent that the Eurodollar
Rate for any Interest Period for such Advances will not adequately reflect the
cost to such Required Lenders of making, funding or maintaining their respective
Eurodollar Rate Advances for such Interest Period, or (ii) if fewer than two
Reference Banks furnish timely information to the Agent for determining the
Eurodollar Rate for any Eurodollar Rate Advances, the Agent shall forthwith so
notify the Borrowers and the Lenders, whereupon (x) each Eurodollar Rate Advance
will automatically, on the last day of any then existing Interest Period
therefor, Convert to a Base Rate Advance, and (y) the obligation of the Lenders
to make, or to Convert Advances into, or to Continue, Eurodollar Rate Advances
shall be suspended until the Agent shall notify the Borrowers and such Lenders
that the circumstances causing such suspension no longer exist.

          (d)  Notwithstanding any other provision of this Agreement, if the
introduction of or any change in or in the interpretation of (to the extent any
such introduction or change occurs after the date hereof) any law or regulation
shall make it unlawful, or any central bank or other governmental authority
having appropriate jurisdiction shall assert in writing that it is unlawful, for
any Lender or its Eurodollar Lending Office to perform its obligations hereunder
to make Eurodollar Rate Advances or to continue to fund or maintain Eurodollar
Rate Advances hereunder, then, on notice thereof and demand therefor by such
Lender to the Borrowers through the Agent, (i) each Eurodollar Rate Advance of
such Lender will automatically, upon such demand, Convert to a Base Rate Advance
and (ii) the obligation of such Lender to make, or to Convert Advances into, or
to Continue, Eurodollar Rate Advances shall be suspended until the Agent shall
notify the Borrowers that such Lender has determined that the circumstances
causing such suspension no longer exist; provided, that, before making any such
demand, such Lender agrees to use reasonable efforts (consistent with its
internal policy and legal and regulatory restrictions) to designate a different
Eurodollar Lending Office if the making of such a designation would allow such
Lender or its Eurodollar Lending Office to continue to perform its obligations
to make Eurodollar Rate Advances or to continue to fund or maintain Eurodollar
Rate Advances and would not, in the judgment of such Lender, be otherwise
disadvantageous to such Lender.

          (e)  Neither Borrower shall be obligated to pay any additional amounts
arising pursuant to clauses (a) and (b) of this Section 2.09 that are
attributable to the Excluded Period with respect to such additional amount;
provided, that if an applicable law, rule, regulation, guideline or request
shall be adopted or made on any date and shall be applicable to the period (a
"Retroactive Period") prior to the date on which such law, rule, regulation,
guideline or request is adopted or made, the limitation on the Borrowers'
obligations to pay such additional amounts hereunder shall not apply to the
additional amounts payable in respect of such Retroactive Period.

          Section 2.10.  Payments and Computations.

          (a)  Each Borrower shall make each payment hereunder and under the
Notes not later than 12:00 Noon (New York City time) on the day when due in U.S.
Dollars to the Agent at the Agent's Account in same day funds and, except as
expressly set forth herein, without deduction, set-off or counterclaim.  The
Agent will promptly thereafter cause to be distributed like funds relating to
the payment of principal or interest or commitment fees under or in respect of a
particular Facility ratably (other than amounts payable pursuant to Section
2.09(a), 2.09(b), 2.11, 2.13(d) or 9.04(c), or amounts payable to an Issuing
Bank in respect of Letters of Credit) to the relevant Lenders for the account of
their Applicable Lending Offices, and like funds relating to the payment of any
other amount payable to any Lender to such Lender for the account of its
Applicable Lending Office, in each case to be applied in accordance with the
terms of this Agreement.  Upon its acceptance of an Assignment and Acceptance
and recording of the information contained therein in the Register pursuant to
Section 9.07(d), from and after the effective date of such Assignment and
Acceptance, the Agent shall make all payments hereunder and under the Notes in
respect of the interest assigned thereby to the Lender assignee thereunder, and
the parties to such Assignment and Acceptance shall make all appropriate
adjustments in such payments for periods prior to such effective date directly
between themselves.

          (b)  If the Agent receives funds for application to the Obligations
under the Loan Documents under circumstances for which the Loan Documents do not
specify the Advances or the Facility to which, or the manner in which, such
funds are to be applied, and neither Borrower has otherwise directed how such
funds are to be applied (which direction is consistent with the terms of the
Loan Documents), the Agent may, but shall not be obligated to, elect to
distribute such funds to each Lender ratably in accordance with such Lender's
proportionate share of the principal amount of all outstanding Advances and the
Available Amount of all Letters of Credit then outstanding, in repayment or
prepayment of such of the outstanding Advances or


                               Credit Agreement

other Obligations owed to such Lender, and for application to such principal
installments, as the Agent shall direct.

          (c)  Each Borrower hereby authorizes each Lender, if and to the extent
payment owed to such Lender is not made when due hereunder or under any Note
held by such Lender, to charge from time to time against any or all of such
Borrower's accounts with such Lender any amount so due (with notice to the Agent
and the relevant Borrower promptly following such charge).

          (d)  Each Reference Bank agrees to furnish to the Agent timely
information for the purpose of determining each Eurodollar Rate.  If any one or
more of the Reference Banks shall not furnish such timely information to the
Agent for the purpose of determining any such interest rate, the Agent shall
determine such interest rate on the basis of timely information furnished by the
remaining Reference Banks.

          (e)  All computations of interest, fees and Letter of Credit
commissions shall be made by the Agent on the basis of a year of 360 days, in
each case for the actual number of days (including the first day but excluding
the last day) occurring in the period for which such interest, fees or
commissions are payable.  Each determination by the Agent of an interest rate,
fee or commission hereunder made in accordance with the provisions of this
Agreement shall be conclusive and binding for all purposes, absent manifest
error.

          (f)  Whenever any payment hereunder or under the Notes shall be stated
to be due on a day other than a Business Day, such payment shall be made on the
next succeeding Business Day, and such extension of time shall in such case be
included in the computation of payment of interest or commitment fee, as the
case may be; provided, that, if such extension would cause payment of interest
on or principal of Eurodollar Rate Advances to be made in the next following
calendar month, such payment shall be made on the immediately preceding Business
Day.

          (g)  Unless the Agent shall have received notice from a Borrower prior
to the date on which any payment is due to any Lender hereunder that such
Borrower will not make such payment in full, the Agent may assume that such
Borrower has made such payment in full to the Agent on such date and the Agent
may, in reliance upon such assumption, cause to be distributed to each such
Lender on such due date an amount equal to the amount then due such Lender.  If
and to the extent such Borrower shall not have so made such payment in full to
the Agent, each such Lender shall repay to the Agent forthwith on demand such
amount distributed to such Lender together with interest thereon, for each day
from the date such amount is distributed to such Lender


                               Credit Agreement

until the date such Lender repays such amount to the Agent, at the Federal Funds
Rate.

          Section 2.11.  Taxes.

          (a)  Any and all payments by each Obligor hereunder or under the
relevant Notes shall be made, in accordance with Section 2.10, free and clear of
and without deduction for any and all present or future taxes, levies, imposts,
deductions, charges or withholdings, and all liabilities with respect thereto,
excluding, in the case of each Issuing Bank, each Lender and the Agent, net
income taxes that are imposed by the United States and franchise taxes and net
income taxes that are imposed on such Issuing Bank, such Lender or the Agent by
the state or foreign jurisdiction under the laws of which such Issuing Bank,
such Lender or the Agent (as the case may be) is organized or any political
subdivision thereof and, in the case of such Issuing Bank and each Lender,
franchise taxes and net income taxes that are imposed on it by the state or
foreign jurisdiction of such Issuing Bank's or such Lender's Applicable Lending
Office or any political subdivision thereof (all such non-excluded taxes,
levies, imposts, deductions, charges, withholdings and liabilities being
hereinafter referred to as "Taxes").  If an Obligor shall be required by law to
deduct any Taxes from or in respect of any sum payable hereunder or under any
Note to any Issuing Bank, any Lender or the Agent, (i) the sum payable shall be
increased as may be necessary so that after making all required deductions
(including deductions applicable to additional sums payable under this Section
2.11) such Issuing Bank, such Lender or the Agent (as the case may be) receives
an amount equal to the sum it would have received had no such deductions been
made, (ii) such Obligor shall make such deductions and (iii) such Obligor shall
pay the full amount deducted to the relevant taxation authority or other
authority in accordance with applicable law.

          (b)  In addition, each Obligor agrees to pay any present or future
stamp or documentary taxes or any other excise or property taxes, charges or
similar levies that arise from any payment made by it hereunder or under the
Notes or from the execution, delivery or registration of this Agreement or the
Notes (hereinafter referred to as "Other Taxes").

          (c)  Each Obligor will indemnify each Issuing Bank, each Lender and
the Agent for the full amount of Taxes or Other Taxes (including, without
limitation, any Taxes or Other Taxes imposed by any jurisdiction on amounts
payable under this Section 2.11) paid by such Issuing Bank, such Lender or the
Agent (as the case may be) and any liability (including penalties, additions to
tax, interest and expenses) arising therefrom or with respect thereto.  This
indemnification shall be made within


                               Credit Agreement

                                     - 53 -

30 days from such date such Issuing Bank, such Lender or the Agent (as the case
may be) makes written demand therefor.

          (d)  Within 30 days after the date of any payment of Taxes, each
Obligor will furnish to the Agent, at its address referred to in Section 9.02,
appropriate evidence of payment thereof.  If such Obligor shall make a payment
hereunder or under the Notes through an account or branch outside the United
States, or a payment is made on behalf of such Obligor by a payor that is not a
United States Person, such Obligor will, if no taxes are payable in respect of
such payment, furnish, or will cause such payor to furnish, to the Agent, at
such address, a certificate from the appropriate taxing authority or
authorities, or an opinion of counsel acceptable to the Agent, in either case
stating that such payment is exempt from or not subject to Taxes. For purposes
of this subsection (d) and subsection (e), the terms "United States" and "United
States Person" shall have the meanings specified in Section 7701 of the Internal
Revenue Code.

          (e)  Each Lender organized under the laws of a jurisdiction outside
the United States shall, on or prior to the date of its execution and delivery
of this Agreement (in the case of each Initial Lender) and on the date of the
Assignment and Acceptance pursuant to which it became a Lender (in the case of
each other Lender), and from time to time thereafter if requested in writing by
either Borrower or the Agent (but only so long as such Lender remains lawfully
able to do so after the date such Lender becomes a Lender hereunder), provide
the Agent and the Borrowers with either (i) Internal Revenue Service form 1001
or 4224, as appropriate, or any successor form prescribed by the Internal
Revenue Service, certifying that such Lender is entitled to benefits under an
income tax treaty to which the United States is a party that reduces the rate of
withholding tax on payments under this Agreement and the Notes or certifying
that the income receivable pursuant to this Agreement and the Notes is
effectively connected with the conduct of a trade or business in the United
States or (ii) Internal Revenue Service form W-8, upon which each Borrower is
entitled to rely, from a Lender that has not at the time such Lender becomes a
Lender hereunder been named in any notice issued by the Secretary of the
Treasury (or such Secretary's authorized delegate) pursuant to Sections
881(c)(2)(B) or 871(h)(5) of the Internal Revenue Code, or any successor form or
statement prescribed by the Internal Revenue Service in order to establish that
such Lender is entitled to treat the interest payments under this Agreement and
the Notes as portfolio interest that is exempt from withholding tax under the
Internal Revenue Code, together with a certificate stating that such Lender is
not described in Section 881(c)(3) of the Internal Revenue Code.  If the form
provided by a Lender at the time such Lender first becomes a party to this
Agreement indicates a United States interest withholding tax rate in excess of
zero (or if the


                               Credit Agreement

                                     - 54 -

Lender cannot provide at such time such form because it is not entitled to
reduced withholding under a treaty, the payments are not effectively connected
income and the payments do not qualify as portfolio interest), withholding tax
at such rate (or at the then existing U.S. statutory rate if the Lender cannot
provide the form) shall be excluded from Taxes unless and until such Lender
provides the appropriate form certifying that a lesser rate applies, whereupon
withholding tax at such lesser rate only shall be excluded from Taxes for
periods governed by such form; provided, that, if at the date of the Assignment
and Acceptance pursuant to which a Lender assignee becomes a party to this
Agreement, the Lender assignor was entitled to payments under subsection (a) in
respect of United States withholding tax with respect to interest paid at such
date, then, to the extent such tax results in liability for such payments, the
term Taxes shall include (in addition to withholding taxes that may be imposed
in the future or other amounts otherwise includable in Taxes) United States
interest withholding tax, if any, applicable with respect to the Lender assignee
on such date.

          (f)  For any period with respect to which a Lender has failed to
provide the Borrowers and the Agent with the appropriate form described in
Section 2.11(e) (other than if such failure is due to a change in law occurring
after the date on which a form originally was required to be provided or if such
form otherwise is not required under subsection (e)), such Lender shall not be
entitled to indemnification under subsection (a) or (c) with respect to Taxes
imposed by the United States.

          (g)  Any Lender or any Issuing Bank claiming any additional amounts
payable pursuant to this Section 2.11 shall use reasonable efforts (consistent
with its internal policy and legal and regulatory restrictions) to change the
jurisdiction of its Applicable Lending Office(s) if the making of such a change
would avoid the need for, or reduce the amount of, any such additional amounts
that may thereafter accrue and would not, in the reasonable judgment of such
Lender or Issuing Bank, be otherwise disadvantageous to such Lender or Issuing
Bank.

          (h)  Without prejudice to the survival of any other agreement of the
Borrowers hereunder, the agreements and obligations of the Borrowers contained
in this Section 2.11 shall survive the payment in full of principal and interest
hereunder and under the Notes.

          Section 2.12.  Sharing of Payments, Etc.  If any Lender shall obtain
any payment (whether voluntary, involuntary, through the exercise of any right
of set-off, or otherwise) on account of the Advances owing to it under any
Facility (other than pursuant to Section 2.09(a), 2.09(b), 2.11, 2.13(d) or
9.04(c), or payments to an Issuing Bank in respect of Letters of Credit) in

excess of its ratable share of payments on account of the Advances under such
Facility obtained by all the relevant Lenders, such Lender shall forthwith
purchase from the other relevant Lenders such participations in the Advances
under such Facility owing to them as shall be necessary to cause such purchasing
Lender to share the excess payment ratably with each of them; provided, that if
all or any portion of such excess payment is thereafter recovered from such
purchasing Lender, such purchase from each relevant Lender shall be rescinded
and such Lender shall repay to the purchasing Lender the purchase price to the
extent of such recovery together with an amount equal to such Lender's ratable
share (according to the proportion of (i) the amount of such Lender's required
repayment to (ii) the total amount so recovered from the purchasing Lender) of
any interest or other amount paid or payable by the purchasing Lender in respect
of the total amount so recovered.  Each Borrower agrees that any Lender so
purchasing a participation from another Lender pursuant to this Section 2.12
may, to the fullest extent permitted by law, exercise all its rights of payment
(including the right of set-off) with respect to such participation as fully as
if such Lender were the direct creditor of such Borrower in the amount of such
participation.

          Section 2.13.  Letters of Credit.

          (a)  Issuance of Letters of Credit, Etc.  Each Borrower may request
one or more Issuing Banks to issue, on the terms and conditions hereinafter set
forth, letters of credit for the account of such Borrower under its respective
Facility (letters of credit so issued under the Terra Facility being herein
called "Terra Letters of Credit" and letters of credit so issued under the TNLP
Facility being herein called "TNLP Letters of Credit"; the Terra Letters of
Credit and the TNLP Letters of Credit being collectively called the "Letters of
Credit") from time to time on any Business Day during the period from the
Restatement Date until the date 90 days prior to the Commitment Termination Date
under the relevant Facility; provided, that:

          (i)  the Terra Commitments shall be utilized under this Section 2.13
     solely for the issuance of Terra Letters of Credit for the account of the
     Company and, to the extent specified by the Company, any of its
     Subsidiaries (other than, prior to the SPU Redemption Time, TNLP or any of
     its Subsidiaries);

          (ii)  the TNLP Commitments shall be utilized under this Section 2.13
     solely for the issuance of TNLP Letters of Credit for the account of TNLP

          (iii)  the aggregate Available Amount of all Letters of Credit issued
     by all Issuing Banks under either Facility shall not exceed at any time the
     Letter of Credit Sublimit for such Facility, and the aggregate outstanding
     principal amount of all Advances under such Facility when added to the
     aggregate amount of Letter of Credit Liabilities under such Facility shall
     not exceed the aggregate Commitments of the relevant Lenders under such
     Facility on such Business Day;

          (iv)  the aggregate amount of all Letter of Credit Liabilities under
     Letters of Credit issued by any Issuing Bank under either Facility shall
     not exceed at any time the Letter of Credit Commitment of such Issuing Bank
     for such Facility; and

          (v)  no Letter of Credit shall have an expiration date later than, or
     shall permit the account party or the beneficiary to require the renewal
     thereof to a date beyond, the date 30 days prior to the Commitment
     Termination Date for the relevant Facility.

On the Restatement Date, all outstanding "Terra Letters of Credit" outstanding
under the Existing Credit Agreement (the "Existing Terra Letters of Credit")
shall automatically, without any action on the part of any Person, be deemed to
be Terra Letters of Credit hereunder for all purposes of this Agreement. On the
Restatement Date, all outstanding "TNLP Letters of Credit" outstanding under the
Existing Credit Agreement (the "Existing TNLP Letters of Credit") shall
automatically, without any action on the part of any Person, be deemed to be
TNLP Letters of Credit hereunder for all purposes of this Agreement.  At the SPU
Redemption Time, all outstanding TNLP Letters of Credit shall automatically,
without any action on the part of any Person, be deemed to be Terra Letters of
Credit hereunder for all purposes of this Agreement.  On each day during the
period commencing with the issuance by an Issuing Bank of any Terra Letter of
Credit (or, in the case of any Existing Terra Letter of Credit, during the
period commencing with the Restatement Date) and until such Letter of Credit
shall have been drawn in full or expired or been terminated, the Terra
Commitment of each Lender shall be deemed to be utilized for all purposes of
this Agreement in an amount equal to such Lender's Pro Rata Share of the then
undrawn amount of such Letter of Credit.  On each day during the period
commencing with the issuance by an Issuing Bank of any TNLP Letter of Credit
(or, in the case of any Existing TNLP Letter of Credit, during the period
commencing with the Restatement Date) and until such Letter of Credit shall have
been drawn in full or expired or been terminated, the TNLP Commitment of each
Lender shall be deemed to be utilized for all purposes of this Agreement

in an amount equal to such Lender's Pro Rata Share of the then undrawn amount of
such Letter of Credit.

          (b)  Request for Issuance.
               -------------------- 

          (i)  Each Letter of Credit shall be issued upon notice, given not
     later than 1:00 P.M. (New York City time) two Business Days prior to the
     date of the proposed issuance of such Letter of Credit, by the relevant
     Borrower to the relevant Issuing Bank, which shall give to the Agent and
     each Lender prompt notice thereof by telex or telecopier. Each such notice
     of issuance of a Letter of Credit (a "Notice of Issuance") shall be by
     telex or telecopier, confirmed promptly in writing, specifying therein (A)
     the requested date of such issuance (which shall be a Business Day), (B)
     the Available Amount requested for such Letter of Credit, (C) the
     expiration date of such Letter of Credit, (D) the account party or parties
     for such Letter of Credit, (E) the name and address of the issuer and the
     beneficiary of such Letter of Credit, and (F) the form of such Letter of
     Credit, together with a description of the nature of the transactions or
     obligations proposed to be supported thereby. If the requested form of such
     Letter of Credit is acceptable to such Issuing Bank in its discretion, such
     Issuing Bank will, upon fulfillment of the applicable conditions set forth
     in Article III, make such Letter of Credit available to the relevant
     Borrower at its office referred to in Section 9.02 or as otherwise agreed
     with such Borrower in connection with such issuance.

          (ii)  Each Issuing Bank shall furnish (A) to the Agent on the first
     Business Day of each week a written report summarizing the issuance and
     expiration dates of Letters of Credit issued by such Issuing Bank during
     the previous week and drawings during such week under all Letters of Credit
     issued by such Issuing Bank, (B) to each Lender and to the relevant
     Borrower on the first Business Day of each month, a written report
     summarizing the issuance and expiration dates of the Letters of Credit
     issued by such Issuing Bank under the relevant Facility during the
     preceding month and drawings during such month under all Letters of Credit
     under such Facility issued by the Issuing Bank and (C) to the Agent and
     each Lender on the first Business Day of each calendar quarter, a written
     report setting forth the average daily aggregate Available Amount during
     the preceding calendar quarter of all Letters of Credit issued by such
     Issuing Bank under the relevant Facility.

          (c)  Drawing and Reimbursement.

          (i)  The payment by an Issuing Bank of a draft drawn under any Letter
     of Credit shall constitute for all purposes of this Agreement the making by
     such Issuing Bank of an advance to the relevant Borrower in the amount of
     such payment, which the relevant Borrower agrees to repay on demand and, if
     not paid on demand, shall bear interest, from the date demanded to the date
     paid in full (and which interest shall be payable on demand), (x) from and
     including the date of demand to but not including the second Business Day
     thereafter at the Base Rate in effect for each such day plus the Applicable
     Margin in effect for each such day, and (y) from and including said second
     Business Day thereafter at the Post-Default Rate. Without limiting the
     obligations of such Borrower hereunder, upon demand by such Issuing Bank
     through the Agent, each Lender having a Commitment under the relevant
     Facility shall make Advances under such Facility in an aggregate amount
     equal to the amount of such Lender's Pro Rata Share of such advance by
     making available for the account of its Applicable Lending Office to the
     Agent for the account of such Issuing Bank, by deposit to the Agent's
     Account, in same day funds, an amount equal to the sum of (A) its Pro Rata
     Share of the outstanding principal amount of such advance plus (B) interest
     accrued and unpaid to and as of such date on the outstanding principal
     amount of such advance.

          (ii)  Each Lender agrees to make such Advances on the Business Day on
     which demand therefor is made by the relevant Issuing Bank through the
     Agent (provided, that notice of such demand is given not later than 12:00
     Noon (New York City time) on such Business Day) or (if notice of such
     demand is given after such time) the first Business Day next succeeding
     such demand.

          (iii)  If and to the extent that any relevant Lender shall not have so
     made the amount of such Advance available to the Agent for account of such
     Issuing Bank, such Lender agrees to pay to the Agent forthwith on demand
     such amount together with interest thereon, for each day from the date of
     demand by the relevant Issuing Bank until the date such amount is paid to
     the Agent, at the Federal Funds Rate.

          (iv)  The Advances provided for in this Section 2.13 shall be made by
     the Lenders irrespective of whether there has occurred and is continuing
     any Default or Event of Default or of whether any other condition precedent
     specified in Article III has not been satisfied, and the obligation of each
     Lender under each relevant Facility to make such Advances is absolute and
     unconditional.

          (d)  Increased Costs.

          (i) If any change in any law or regulation or in the interpretation
     thereof (to the extent any such change occurs after the date hereof) by any
     court or administrative or governmental authority charged with the
     administration thereof shall either (x) impose, modify or deem applicable
     any reserve, special deposit or similar requirement against letters of
     credit or guarantees issued by, or assets held by, or deposits in or for
     the account of, any Issuing Bank or any Lender or (y) impose on any Issuing
     Bank or any Lender any other condition regarding this Agreement or such
     Issuing Bank or such Lender or any Letter of Credit, and the result of any
     event referred to in the preceding clause (x) or (y) shall be to increase
     the cost to such Issuing Bank or Lender of issuing or maintaining any
     Letter of Credit or any commitment hereunder in respect of Letters of
     Credit, then, upon demand by such Issuing Bank or such Lender, the
     Borrowers shall immediately pay to such Issuing Bank or such Lender, from
     time to time as specified by such Issuing Bank or such Lender, additional
     amounts that shall be sufficient to compensate such Issuing Bank or such
     Lender for such increased cost. A certificate as to the amount of such
     increased cost, submitted to the Borrowers by such Issuing Bank or such
     Lender shall be conclusive and binding for all purposes, absent manifest
     error.

          (ii)  Neither Borrower shall be obligated to pay any additional
     amounts arising pursuant to this Section 2.13(d) that are attributable to
     the Excluded Period with respect to such additional amounts; provided, that
     if an applicable law, rule, regulation, guideline or request shall be
     adopted or made on any date and shall be applicable to the period (a
     "Retroactive Period") prior to the date on which such law, rule,
     regulation, guideline or request is adopted or made, the limitation on
     either Borrower's obligation to pay such additional amounts hereunder shall
     not apply to the additional amounts payable in respect of such Retroactive
     Period.

          (e)  Obligations Absolute.  The Obligations of each Borrower under
this Agreement and any other agreement or instrument relating to any Letter of
Credit (as hereafter amended, supplemented or otherwise modified from time to
time, collectively, the "L/C Related Documents") shall, to the extent permitted
by law, be unconditional and irrevocable, and shall be paid strictly in
accordance with the terms of such L/C Related Document under all circumstances,
including, without limitation, the following circumstances:

          (i)  any lack of validity or enforceability of any one or more of such
     other documents and agreements, including, but not limited to, the L/C
     Related Documents;

          (ii)  any change in the time, manner or place of payment of, or in any
     other term of, all or any of the Obligations of such Borrower in respect of
     any L/C Related Document or any other amendment or waiver of or any consent
     to departure from all or any of the L/C Related Documents;

          (iii)  the existence of any claim, set-off, defense or other right
     that such Borrower may have at any time against any beneficiary or any
     transferee of a Letter of Credit (or any Persons for whom any such
     beneficiary or any such transferee may be acting), any Issuing Bank or any
     other Person, whether in connection with the transactions contemplated by
     the L/C Related Documents or any unrelated transaction;

          (iv)  any statement or any other document presented under a Letter of
     Credit proving to be forged, fraudulent, invalid or insufficient in any
     respect or any statement therein being untrue or inaccurate in any respect;

          (v)  payment by an Issuing Bank under a Letter of Credit against
     presentation of a draft or certificate that does not comply with the terms
     of such Letter of Credit, except to the extent that such payment resulted
     from such Issuing Bank's willful misconduct or gross negligence in
     determining whether such draft or certificate complies on its face with the
     terms of such Letter of Credit;

          (vi)  any exchange, release or nonperfection of any Collateral or
     other collateral, or any release or amendment or waiver of or consent to
     departure from any guarantee, for all or any of the Obligations of such
     Borrower in respect of the L/C Related Documents; or

          (vii)  any other circumstance or happening whatsoever, whether or not
     similar to any of the foregoing, including, without limitation, any other
     circumstance that might otherwise constitute a defense available to, or a
     discharge of, such Borrower or a guarantor.

          Section 2.14.  Replacement of Lender.

          (a)  Subject to clause (c) below, in the event that any Lender
requests compensation pursuant to Section 2.09(a), 2.09(b) or 2.13(d), or the
obligation of any Lender to make, or to Convert Base Rate Advances into, or to
Continue, Eurodollar Rate Advances shall be suspended pursuant to Section
2.09(c) or

2.09(d) (such Lender being herein called an "Affected Lender"), then, so long as
such condition exists, the Borrowers may, after the date 30 days after the date
of such request or suspension, either:

          (i)  (x) designate an Eligible Assignee acceptable to the Agent and
     each Issuing Bank (which acceptance will not be unreasonably withheld) that
     is not an Affiliate of the Borrowers (such Eligible Assignee being herein
     called a "Replacement Lender") to assume the Affected Lender's Commitments
     and other obligations hereunder and to purchase the Affected Lender's
     Advances and other rights under the Loan Documents (all without recourse to
     or representation or warranty by, or expense to, the Affected Lender) for a
     purchase price equal to the aggregate principal amount of the outstanding
     Advances held by the Affected Lender plus all accrued but unpaid interest
     on such Advances and accrued but unpaid fees owing to the Affected Lender
     (and upon such assumption, purchase and substitution, and subject to the
     execution and delivery to the Agent by the Replacement Lender of
     documentation satisfactory to the Agent and compliance with the
     requirements of Section 9.07(c), the Replacement Lender shall succeed to
     the rights and obligations of the Affected Lender hereunder and the other
     Loan Documents), and (y) pay to the Affected Lender all amounts payable to
     such Affected Lender under Section 9.04(c), calculated as if the purchase
     by the Replacement Lender constituted a mandatory prepayment of Advances by
     the Borrowers, and (z) pay to the Agent the processing and recordation fee
     specified in Section 9.07(a)(vi) with respect to such assignment; or

          (ii)  (x) terminate the Commitments of the Affected Lender and (y) pay
     to the Affected Lender the aggregate principal amount of the outstanding
     Advances held by the Affected Lender plus all accrued but unpaid interest
     on such Advances and accrued but unpaid fees owing to the Affected Lender
     plus all amounts payable to the Affected Lender under Section 9.04(c) as a
     result of such prepayment.

In the event that the Borrowers exercise their rights under the preceding
sentence, the Affected Lender shall no longer be a party hereto or have any
rights or obligations hereunder or under the other Loan Documents; provided,
that the obligations of the Borrowers to the Affected Lender under Sections
2.09, 2.11 and 9.04 with respect to events occurring or obligations arising
before or as a result of such replacement shall survive such exercise.

          (b)  If the Borrowers exercise their rights under clause (a)(ii)
above, the Borrowers may, not later than the date


                               Credit Agreement

60 days after such exercise, designate an Eligible Assignee acceptable to the
Agent and each Issuing Bank (which acceptance will not be unreasonably withheld)
that is not an Affiliate of the Borrowers (such Eligible Assignee being herein
called a "Substitute Lender") to assume Commitments hereunder and to make
Advances hereunder in an amount equal to the respective Commitments and Advances
of the Affected Lender under each of the Facilities and, subject to (x) the
execution and delivery to the Agent by the Substitute Lender of documentation
satisfactory to the Agent, (y) the payment by the Borrowers to the Agent of the
processing and recordation fee specified in Section 9.07(a)(vi) with respect to
such assignment, and (z) compliance with Section 9.07(c), the Substitute Lender
shall succeed to the rights and obligations of the Affected Lender hereunder and
under the other Loan Documents.  Upon the Substitute Lender so becoming a party
hereto, the Borrowers shall borrow Advances from the Substitute Lender and/or
prepay the principal of the Advances of the other Lenders in such manner as will
result in the outstanding principal amount of the Advances under each Facility
being held by the Lenders according to their respective Pro Rata Shares of the
relevant Facilities.

          (c)  The Borrowers may not exercise their rights under this 
Section 2.14:

          (i)  with respect to any Affected Lender unless the Borrowers
     simultaneously exercise such rights with respect to all Affected Lenders,

          (ii)  if a Default or an Event of Default has occurred and is then
     continuing, or

          (iii)  with respect to any exercise of rights under clause (b) above,
     if, at the time of such exercise, the aggregate amount of the Commitments
     that shall have been terminated pursuant to said clause (b) (including the
     Commitments then proposed to be terminated) shall exceed 30% of the
     aggregate amount of the Commitments in effect on the Restatement Date.

     Subsidiary, as the case may be, and that the loss thereof will not have a
     Material Adverse Effect.

          (f)  Visitation Rights.  At any reasonable time and as may be
     reasonably requested from time to time, permit the Agent, any Issuing Bank

     Obligor shall provide to the Agent within a reasonable time after such
     acquisition or request, as the case may be, at the expense of such Obligor,
     an environmental site assessment report for the acquired property (in the
     case of an acquisition as described in clause (i)) or for any properties of
     such Obligor which are the subject of any such Default or Event of Default
     (in the case of an event as described in clause (ii)) prepared by an
     environmental consulting firm reasonably acceptable to the Agent,
     indicating the presence or absence of Hazardous Materials and the estimated
     cost of any compliance, removal or remedial action in connection with any
     Hazardous Materials on such properties (provided, that if such Obligor, in
     the exercise of its reasonable judgment, determines not to have such an
     environmental site assessment report prepared, such Obligor shall instead
     deliver to the Agent a copy of such Obligor's internal site assessment
     report relating to relevant property). Without limiting the generality of
     the foregoing, if the Agent determines at any time that a material risk
     exists that any such report will not be provided within a reasonable time
     following such request, the Agent may retain an environmental consulting
     firm to prepare such report at the expense of such Obligor, such Obligor
     and each of its Subsidiaries hereby granting to the Agent, such firm and
     any agents or representatives thereof an irrevocable non-exclusive license,

     GAAP.

          (i)  Maintenance of Properties, Etc.  Maintain and preserve, and cause
     each of its Material Subsidiaries to maintain and preserve, except to the
     extent the failure to do so could not reasonably be expected to have a
     Material Adverse Effect, all of its properties that are used or useful in
     the conduct of its business in good working order and condition, ordinary
     wear and tear excepted.

          (j)  Compliance with Terms of Leaseholds.  Make all payments and
     otherwise perform all obligations in respect of all leases of real
     property, keep such leases in full force and effect and not allow such
     leases to lapse or be terminated or any rights to renew such leases to be

     Subsidiaries to do so.

          (k)  Performance of Related Documents.  Perform and observe all of the
     terms and provisions of each Related Document to be performed or observed
     by it, maintain each such Related Document in full force and effect and
     enforce such Related Document in accordance with its terms, except to the
     extent the failure to do any of the foregoing could not reasonably be
     expected to have a Material Adverse Effect.

     observe, and cause each of its Subsidiaries to perform and observe, all the
     terms and provisions of each Material Contract to be performed or observed
     by it, maintain each such Material Contract in full force and effect and
     enforce each such Material Contract in accordance with its terms, except to
     the extent the failure to do any of the foregoing could not reasonably be
     expected to have a Material Adverse Effect.

          (m)  Transactions with Affiliates.  Conduct, and cause each of its
     Subsidiaries to conduct, all transactions otherwise permitted under the
     Loan Documents with any of its Affiliates on terms that are fair and
     reasonable and no less favorable to such Obligor or such Subsidiary than
     would obtain in a comparable arm's-length transaction with a Person that is
     not an Affiliate; provided, that this Section 5.01(m) shall not be
     applicable to

               (i)  the transactions expressly contemplated by the Related
          Documents;

          officer of such Obligor or any director or officer of a Subsidiary of
          such Obligor serving at the direction or request of such Obligor to
          the extent such compensation is determined in the good faith exercise
          of business judgment by the Board of Directors of such Obligor to be
          reasonable and appropriate to the functions of such office;

     Agent or any Lender or Issuing Bank through the Agent correct, and cause
     each Subsidiary promptly to correct, any material defect or error that may
     be discovered in any Loan Document, which material defect or error is the
     result of any untrue statement of material fact under any Loan Document or
     the omission to state a material fact necessary to make the statements made
     therein not misleading, or in the execution, acknowledgment or recordation
     of any Loan Document, and (ii) promptly upon reasonable request by the

     Obligor's and its Subsidiaries' properties, rights or interests covered or
     now or hereafter intended to be covered by any of the Security Documents,
     (B) perfect and maintain the validity, effectiveness and priority of any of
     the Security Documents and the Liens intended to be created thereby and (C)
     assure, convey, grant, assign, transfer, preserve, protect and confirm more

Bank agrees that, upon such execution and delivery, it will be bound by the Loan
Purchase Agreement as if such Lender or Issuing Bank, as the case may be, were a

misconduct.  Without limitation of the generality of the foregoing, the Agent

Eligible Assignee, as assignee, as provided in Section 9.07; (ii) may consult

Commitments, the Advances made by it and the Notes issued to it, Citibank shall
have the same rights and powers under the Loan Documents as any other Lender and

into this Agreement.  Each Lender and each Issuing Bank also acknowledges that

any other Lender and

based on such documents and information as it shall deem appropriate at the
time, continue to make its own credit decisions in taking or not taking action
under this Agreement.

          Section 7.05.  Indemnification.  The Lenders agree to indemnify the
Agent (to the extent not promptly reimbursed by the Borrowers), ratably
according to the principal amounts of the Notes then held by each of them (or if
no Advances are at the time outstanding, ratably according to the amounts of
their Commitments), from and against any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind or nature whatsoever that may be imposed on, incurred
by, or asserted against any of them in any way relating to or arising out of the
Loan Documents or any action taken or omitted by any of them under the Loan
Documents; provided, that no Lender shall be liable for any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements resulting from the gross negligence or willful
misconduct of the Agent.  Without limitation of the foregoing, each Lender
agrees to reimburse the Agent promptly upon demand for its ratable share of any
costs and expenses payable by the Borrowers under Section 9.04 of this

reimbursed for such costs and expenses by the Borrowers.

          Section 7.06.  Collateral Duties.

          (a)  Except for action expressly required of the Agent hereunder and
under the Security Documents, the Agent shall in all cases be fully justified in
refusing to act hereunder and thereunder unless it shall be further indemnified
to its satisfaction by the Lenders and the Issuing Banks proportionately in
accordance with the Obligations then due and payable to each of them against any
and all liability and expense that may be incurred by it by reason of taking or
continuing to take any such action.

          (b)  Except as expressly provided herein, the Agent shall have no duty
to take any affirmative steps with respect to the collection of amounts payable
in respect of the Collateral. The Agent shall incur no liability as a result of
any private sale of the Collateral.

          (c)  The Lenders and the Issuing Banks hereby consent, and agree upon
written request by the Agent to execute and deliver such instruments and other
documents as the Agent may deem desirable to confirm such consent, to the
release of the


                               Credit Agreement

Liens on any of the Collateral, including any release in connection with any
sale, transfer or other disposition of the Collateral or any part thereof in
accordance with the Loan Documents.

          (d)  The Agent shall be deemed to have exercised reasonable care in
the custody and preservation of the Collateral in its possession if the
Collateral is accorded treatment substantially equal to that which the Agent
accords its own property, it being understood that none of the Agent, any Lender
or any Issuing Bank shall have responsibility for (a) ascertaining or taking
action with respect to calls, conversions, exchanges, maturities, tenders or
other matters relative to any Collateral, whether or not the Agent, any Lender
or any Issuing Bank has or is deemed to have knowledge of such matters, or (b)
taking any necessary steps to preserve rights against any parties with respect
to any Collateral.

          Section 7.07.  Successor Agent.  The Agent may resign at any time by
giving written notice thereof to the Issuing Banks, the Lenders and the
Borrowers and may be removed at any time with or without cause by the Required
Lenders.  Upon any such resignation or removal, the Required Lenders shall have
the right to appoint (subject, so long as no Default or Event of Default has
occurred and is continuing, to the consent of the Borrowers, which consent shall
not be unreasonably withheld) a successor Agent.  If no successor Agent shall
have been so appointed by the Required Lenders, and shall have accepted such
appointment, within 30 days after the retiring Agent's giving of notice of
resignation or the Required Lenders' removal of the Agent, as the case may be,
then the retiring Agent may, on behalf of the Issuing Banks and the Lenders,
appoint (subject, so long as no Default or Event of Default has occurred and is
continuing, to the consent of the Borrowers, which consent shall not be
unreasonably withheld) a successor Agent, which shall be an Initial Lender or a
commercial bank organized under the laws of the United States or of any State
thereof and having a combined capital and surplus of at least $500,000,000.
Upon the acceptance of any appointment as Agent hereunder by a successor Agent
such successor Agent shall succeed to and become vested with all the rights,
powers, discretion, privileges and duties of the retiring Agent, as the case may
be, and such retiring Agent shall be discharged from its duties and obligations
under the Loan Documents.  After any retiring Agent's resignation or removal
hereunder as Agent, the provisions of this Article VII shall inure to the
benefit of the Agent as to any actions taken or omitted to be taken by it while
it was Agent under this Agreement and under the Security Documents.

          Section 8.02.  Obligations Unconditional.

          (a)  The obligations of the Terra Guarantors under Section 8.01 are
absolute and unconditional, joint and several, irrespective of the value,
genuineness, validity, regularity or enforceability of the obligations of the
Company under this Agreement, the Notes or any other agreement or instrument
referred to herein or therein, or any substitution, release or exchange of any
other guarantee of or security for any of the Terra Guaranteed Obligations, and,
to the fullest extent permitted by applicable law, irrespective of any other
circumstance whatsoever that might otherwise constitute a legal or equitable
discharge or defense of a surety or guarantor, it being the intent of this
Section 8.02 that the obligations of the Terra Guarantors hereunder shall be
absolute and unconditional, joint and several, under any and all circumstances.

          (b)  The obligations of the TNLP Guarantors under Section 8.01 are

          (c)  Without limiting the generality of the foregoing clauses (a) and

not alter or impair the liability of the Guarantors hereunder which shall remain
absolute and unconditional as described above:

          (i)  at any time or from time to time, without notice to the

     or any right under this Agreement or the Notes or any other agreement or
     instrument referred to herein or therein shall be waived or any other
     guarantee of any of the Guaranteed Obligations or any security therefor
     shall be released or exchanged in whole or in part or otherwise dealt with;
     or

          (iv)  any lien or security interest granted to, or in favor of, the
     Agent, any Issuing Bank or any Lender as security for any of the Guaranteed
     Obligations shall fail to be perfected.

The Guarantors hereby expressly waive diligence, presentment, demand of payment,
protest and all notices whatsoever, and any requirement that the Agent, any
Issuing Bank or any Lender exhaust any right, power or remedy or proceed against
either Borrower under this Agreement or the Notes or any other agreement or
instrument referred to herein or therein, or against any other Person under any
other guarantee of, or security for, any of the Guaranteed Obligations.

          Section 8.03.  Reinstatement.  The obligations of the Guarantors under
this Section 8 shall be automatically reinstated if and to the extent that for
any reason any payment by or on behalf of the relevant Borrower in respect of

of any proceedings in bankruptcy or reorganization or otherwise, and the
relevant Guarantors jointly and severally agree that they will indemnify the
Agent, each Issuing Bank and each Lender on demand for all reasonable costs and
expenses (including, without limitation, fees of counsel) incurred by the Agent,
such Issuing Bank or such Lender in connection with such rescission or
restoration, including any such costs and expenses incurred in defending against
any claim alleging that such payment constituted a preference, fraudulent
transfer or similar payment under any bankruptcy, insolvency or similar law.

          Section 8.04.  Subrogation.  To the extent that, as a result of this
Article VIII, any Lender or Issuing Bank would be subject to an extended
preference period under Section 547 of the Bankruptcy Code, each Guarantor
hereby waives all rights of subrogation, whether arising by contract or
operation of law (including, without limitation, any such right arising under
the Bankruptcy Code) or otherwise, by reason of any payment by it pursuant to
the provisions of this Section 8 and agrees with the relevant Borrower for the
benefit of each of its creditors (including, without limitation, each Lender,
each Issuing Bank and the Agent) that any such payment by it shall constitute a
contribution of capital by such Guarantor to the relevant

Borrower (or an investment in the equity capital of the relevant Borrower by
such Guarantor).

          Section 8.05.  Remedies.  The Guarantors jointly and severally agree
that, as between the Guarantors and the Lenders and the Issuing Banks, the
obligations of the Borrowers under this Agreement and the Notes may be declared
to be forthwith due and payable as provided in Section 6 (and shall be deemed to
have become automatically due and payable in the circumstances provided in said
Section 6) for purposes of Section 8.01 notwithstanding any stay, injunction or
other prohibition preventing such declaration (or such obligations from becoming
automatically due and payable) as against the relevant Borrower and that, in the
event of such declaration (or such obligations being deemed to have become
automatically due and payable), such obligations (whether or not due and payable
by the relevant Borrower) shall forthwith become due and payable by the
Guarantors for purposes of said Section 8.01.

          Section 8.06.  Instrument for the Payment of Money. Each Guarantor
hereby acknowledges that the guarantee in this Section 8 constitutes an
instrument for the payment of money, and consents and agrees that any Lender,
any Issuing Bank or the Agent, at its sole option, in the event of a dispute by
such Guarantor in the payment of any moneys due hereunder, shall have the right
to bring motion-action under New York CPLR Section 3213.

          Section 8.07.  Continuing Guarantee.  The guarantee in this Section 8
is a continuing guarantee, and shall apply to all Guaranteed Obligations
whenever arising.

          Section 8.08.  Rights of Contribution.  The Subsidiary Guarantors
hereby agree, as between themselves, that if any Subsidiary Guarantor shall
become an Excess Funding Guarantor (as defined below) by reason of the payment
by such Subsidiary Guarantor of any Guaranteed Obligations, each other
Subsidiary Guarantor shall, on demand of such Excess Funding Guarantor (but
subject to the next sentence), pay to such Excess Funding Guarantor an amount
equal to such Subsidiary Guarantor's Pro Rata Portion (as defined below and
determined, for this purpose, without reference to the properties, debts and
liabilities of such Excess Funding Guarantor) of the Excess Payment (as defined
below) in respect of such Guaranteed Obligations.  The payment obligation of a
Subsidiary Guarantor to any Excess Funding Guarantor under this Section 8.08
shall be subordinate and subject in right of payment to the prior payment in
full of the obligations of such Subsidiary Guarantor under the other provisions
of this Section 8 and such Excess Funding Guarantor shall not exercise any right
or remedy with respect to such

excess until payment and satisfaction in full of all of such obligations.

          For purposes of this Section 8.08, (i) "Excess Funding Guarantor"
shall mean, in respect of any Guaranteed Obligations, a Subsidiary Guarantor
that has paid an amount in excess of its Pro Rata Portion of such Guaranteed
Obligations, (ii) "Excess Payment" shall mean, in respect of any Guaranteed
Obligations, the amount paid by an Excess Funding Guarantor in excess of its Pro
Rata Portion of such Guaranteed Obligations and (iii) "Pro Rata Portion" shall
mean, for any Subsidiary Guarantor, the ratio (expressed as a percentage) of (x)
the amount by which the aggregate present fair saleable value of all properties
of such Subsidiary Guarantor (excluding any shares of stock of any other
Subsidiary Guarantor) exceeds the amount of all the debts and liabilities of
such Subsidiary Guarantor (including contingent, subordinated, unmatured and
unliquidated liabilities, but excluding the obligations of such Subsidiary
Guarantor hereunder and any obligations of any other Subsidiary Guarantor that
have been Guaranteed by such Subsidiary Guarantor) to (y) the amount by which
the aggregate fair saleable value of all properties of the Company and all of
the Subsidiary Guarantors exceeds the amount of all the debts and liabilities
(including contingent, subordinated, unmatured and unliquidated liabilities, but
excluding the obligations of the Company and the Subsidiary Guarantors
hereunder) of the Company and all of the Subsidiary Guarantors, all as of the
Closing Date.  If any Subsidiary becomes a Subsidiary Guarantor hereunder
subsequent to the Closing Date, then for purposes of this Section 8.08 such
subsequent Subsidiary Guarantor shall be deemed to have been a Subsidiary
Guarantor as of the Closing Date and the aggregate present fair saleable value
of the properties, and the amount of the debts and liabilities, of such
Subsidiary Guarantor as of the Closing Date shall be deemed to be equal to such
value and amount on the date such Subsidiary Guarantor becomes a Subsidiary
Guarantor hereunder.

          Section 8.09.  General Limitation on Guarantee Obligations.  In any
action or proceeding involving any state corporate law, or any state or Federal
bankruptcy, insolvency, reorganization or other law affecting the rights of
creditors generally, if the obligations of any Guarantor under Section 8.01
would otherwise, taking into account the provisions of Section 8.08, be held or
determined to be void, invalid or unenforceable, or subordinated to the claims
of any other creditors, on account of the amount of its liability under said
Section 8.01, then, notwithstanding any other provision hereof to the contrary,
the amount of such liability shall, without any further action by such
Guarantor, any Lender, any Issuing Bank, the Agent or any other Person, be
automatically limited and reduced to the highest amount that is valid and
enforceable and

          Section 9.03.  No Waiver; Remedies.  No failure on the part of any
Lender, any Issuing Bank or the Agent to exercise, and no delay in exercising,
any right hereunder or under any Note shall operate as a waiver thereof; nor

Merger and the Second Merger referred to therein and any of the other
transactions contemplated thereby (collectively, the "Merger Transactions") or
(iv) the actual or alleged presence of Hazardous Materials on any property owned

indirect, consequential or punitive damages arising out of or otherwise relating
to the Reorganization Transaction or any part thereof, the SPU Redemption or any
part thereof, the Merger Transactions or any part thereof or the other
transactions contemplated herein or in any other Loan Document or the actual or
proposed use of the proceeds of the Advances.  For purposes of this Section
9.04(b), the term "non-appealable" includes any judgment as to which all appeals
have been taken or as to which the time for taking an appeal shall have expired.

          (c)  If any payment of principal of, or Conversion of, any Eurodollar
Rate Advance is made by a Borrower to or for the account of a relevant Lender
other than on the last day of the Interest Period for such Advance, as a result
of a payment or Conversion pursuant to Section 2.03, 2.05, 2.08(b)(i) or 2.09(d)
or as the result of acceleration of the maturity of the Notes pursuant to
Section 6.01 or for any other reason, such Borrower shall, upon demand by such
Lender (with a copy of such demand to the Agent), pay to the Agent for the
account of such Lender any amounts required to compensate such Lender for any
additional losses, costs or expenses that it may reasonably incur as a result of
such payment, including, without limitation, any loss (including loss of
anticipated profits), cost or expense incurred by reason of the liquidation or
reemployment of deposits or other funds acquired by any Lender to fund or

amounts payable by it under any Loan Document, including, without limitation,

          Section 9.05.  Right of Setoff.  Upon (a) the occurrence and during
the continuance of any Event of Default and (b) the making of the request or the
granting of the consent specified by Section 6.01 to authorize the Agent to
declare the Notes due and payable pursuant to the provisions of Section 6.01,
each Lender is hereby authorized at any time and from time to time, to the
fullest extent permitted by law, to set off and otherwise apply any and all
deposits (general or special, time or demand, provisional or final) at any time
held and other indebtedness at any time owing by such Lender to or for the
credit or the account of each Borrower against any and all of the Obligations of
such Borrower now or hereafter existing under this Agreement and the Note held
by such Lender, irrespective of whether such Lender shall have made any demand
under this Agreement or such Note and although such obligations may be
unmatured.  Each Lender agrees promptly to notify the relevant Borrower after
any such setoff and application; provided, that


                               Credit Agreement

application.  The rights of each Lender under this Section are in addition to
other rights and remedies (including, without limitation, other rights of
setoff) that such Lender may have.

nonexclusive jurisdiction of the United States District Court for the Southern
District of New York and of any New York state court sitting in New York City
for the purposes of all legal proceedings arising out of or relating to this
Agreement or the transactions contemplated hereby.  Each Obligor irrevocably
waives, to the fullest extent permitted by applicable law, any objection that it
may now or hereafter have to the laying of the venue of any such proceeding
brought in such a court and any claim that any such proceeding brought in such a
court has been brought in an inconvenient forum.

          Section 9.07.  Assignments and Participations.

          (a)  Each Lender may assign to one or more banks or other entities all

     assignment of all of a Lender's rights and obligations under this
     Agreement, the amount of the Commitments of the assigning Lender being
     assigned pursuant to each such assignment (determined as of the date of the
     Assignment and Acceptance with respect to such assignment) shall in no
     event be less than the lesser of (x) such Lender's Commitments hereunder
     and (y) $5,000,000 or an integral multiple of $1,000,000 in excess thereof
     (except as otherwise agreed by the relevant Borrower and the Agent),

          (ii) except in the case of an assignment to a Person that, immediately

     relevant Borrower, the Agent and each Issuing Bank, such approval not to be
     unreasonably withheld,

          (iii)  each such assignment shall be to an Eligible Assignee,

          (iv) each such assignment by a Lender of its Advances, Commitment or
     Note under any Facility shall be made in such manner so that the same
     portion of its Advances, Commitment and Note under such Facility is
     assigned to the respective assignee,

          (v) each such assignment by a Lender of its Advances, Commitments and
     Notes shall be made in such a manner so that the same portion of its Terra
     Advances, TNLP Advances, Terra Commitment, TNLP Commitment, Terra Note and
     TNLP Note is assigned to the respective assignee, and

          (vi) the parties to each such assignment shall execute and deliver to
     the Agent, for its acceptance and recording in the Register, an Assignment
     and Acceptance, together with any Note or Notes subject to such assignment
     and a processing and recordation fee of $3,000.

Upon such execution, delivery, acceptance and recording, from and after the
effective date specified in such Assignment and Acceptance, (x) the assignee
thereunder shall be a party hereto and, to the extent that rights and
obligations hereunder have been assigned to it pursuant to such Assignment and
Acceptance, have the rights and obligations of a Lender hereunder and (y) the
Lender assignor thereunder shall, to the extent that rights and obligations
hereunder have been assigned by it pursuant to such Assignment and Acceptance,
relinquish its rights and be released from its obligations under this Agreement
(and, in the case of an Assignment and Acceptance covering all or the remaining
portion of an assigning Lender's rights and obligations under this Agreement,
such Lender shall cease to be a party hereto).

          (b)  By executing and delivering an Assignment and Acceptance, the
Lender assignor thereunder and the assignee thereunder confirm to and agree with
each other and the other parties hereto as follows:  (i) other than as provided
in such Assignment and Acceptance, such assigning Lender makes no representation

deemed appropriate to make its own credit analysis and decision to enter into
such Assignment and Acceptance; (iv) such assignee will, independently and

assignee agrees that it will perform in accordance with their terms all of the
obligations that by the terms of this Agreement are required to be performed by
it as a Lender.

          (c)  The Agent, acting for this purpose as an agent of the Borrowers,
shall maintain at its address referred to in Section 9.02 a copy of each
Assignment and Acceptance delivered to and accepted by it and a register for the
recordation of the names and addresses of the Lenders and the Commitments of,
and principal amount of the Advances owing under each Facility to, each Lender
from time to time (the "Register").  The entries in the Register shall be
conclusive and binding for all purposes, absent manifest error, and the
Borrowers, the Agent and the Lenders shall treat each Person whose name is
recorded in the Register as a Lender hereunder for all purposes of this
Agreement.  No assignment shall be effective until it is recorded in the
Register pursuant to this Section 9.07(c).  The Register shall be available for
inspection by the Borrowers or any Lender at any reasonable time and from time
to time upon reasonable prior notice.

          (d)  Upon its receipt of an Assignment and Acceptance executed by an
assigning Lender and an assignee, together with any Note or Notes subject to
such assignment, the Agent shall, if such Assignment and Acceptance has been
completed and is in substantially the form of Exhibit F hereto, (i) accept such
Assignment and Acceptance, (ii) record the information contained therein in the
Register and (iii) give prompt notice thereof to the Borrowers.  Within five
Business Days after its receipt of such notice, the relevant Borrower, at its
own expense, shall execute and deliver to the Agent in exchange for the
surrendered Note or Notes a new Note or Notes to the order of such assignee in
an amount equal to the portion of the Facilities assumed by it pursuant to such
Assignment and Acceptance and, if the assigning Lender has retained a portion of
such Facilities, a new Note or Notes to the order of the assigning Lender in an
amount equal to the portion so retained by it hereunder.  Such new Note or Notes
shall be in an aggregate principal amount equal to the aggregate principal
amount of such surrendered Note or Notes, shall be

Notes held by it); provided, that (i) such Lender's obligations under this
Agreement (including, without limitation, its Commitments) shall remain
unchanged, (ii) such Lender shall remain solely responsible to the other parties
hereto for the performance of such obligations, (iii) such Lender shall remain
the holder of any such Note for all purposes of this Agreement, (iv) the

rights and obligations under this Agreement and (v) no participant under any
such participation shall have any right to approve any amendment or waiver of
any provision of any Loan Document, or any consent to any departure by any
Obligor therefrom, except to the extent that such amendment, waiver or consent
would reduce the principal of, or interest on, the Notes or any fees or other
amounts payable hereunder, in each case to the extent subject to such
participation, postpone any date fixed for any payment of principal of, or
interest on, the Notes or any fees or other amounts payable hereunder, in each
case to the extent subject to such participation, or release all or
substantially all of the Collateral.

          (f)  Any Issuing Bank may (subject to the prior written consent of
Terra, such consent not to be unreasonably withheld) assign all or any portion
of its rights and obligations under this Agreement to one or more successor
Issuing Banks that is a commercial bank organized under the laws of the United
States, or any state thereof, and having total assets in excess of
$1,000,000,000 and, upon the acceptance of such assignment, the respective
successor Issuing Banks shall succeed to such portion of such rights and
obligations and such assigning Issuing Bank shall be discharged from its duties
and obligations under this Agreement to such extent, including, without
limitation, such portion of its Letter of Credit Commitment.

          (g)  Any Issuing Bank and any Lender may, in connection with any
assignment or participation or proposed assignment or participation pursuant to
this Section 9.07, disclose to the assignee or participant or proposed assignee
or participant, any information relating to the Borrower furnished to such
Lender by or on behalf of the Borrower; provided, that, prior to any such
disclosure, the assignee or participant or proposed assignee or participant
shall agree in writing to preserve the

Bank or Lender.

          (h)  Notwithstanding any other provision set forth in this Agreement,
any Lender may at any time create a security interest in all or any portion of
its rights under this Agreement (including, without limitation, the Advances
owing to it and the Note or Notes held by it) in favor of any Federal Reserve
Bank in accordance with Regulation A of the Board of Governors of the Federal
Reserve System.

          (i)  Anything in this Section 9.07 to the contrary notwithstanding,
each Lender shall be permitted to pledge all or any part of its right, title and
interest in, to and under the Advances and Notes held by it to any trustee for
the benefit of the holders of such Lender's securities.

          (j)  Anything in this Section 9.07 to the contrary notwithstanding,
neither Terra nor any of its Subsidiaries or Affiliates may acquire (whether by
assignment, participation or otherwise), and no Lender or Issuing Bank shall
assign or participate to Terra or any of its Subsidiaries or Affiliates, any
interest in any Commitment, Advance or other amount owing hereunder without the
prior consent of each Lender; provided, that the Lenders and the Issuing Banks
may assign all of their interests in the Commitments, Advances and such other
amounts pursuant to the Loan Purchase Agreement.

          Section 9.08.  Execution in Counterparts.  This Agreement may be
executed in any number of counterparts and by different parties hereto 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. Delivery of an executed counterpart of a signature page to this
Agreement by telecopier shall be effective as delivery of a manually executed
counterpart of this Agreement.

          Section 9.09.  No Liability of the Issuing Banks.  Each Borrower

any Letter of Credit with respect to its use of such Letter of Credit.  Neither
the relevant Issuing Bank nor any of its officers or directors shall be liable
or responsible for:  (a) the use that may be made of any Letter of Credit or any
acts or omissions of any beneficiary or transferee in connection therewith; (b)
the validity, sufficiency or genuineness of documents, or of any endorsement
thereon, even if such documents should prove to be in any or all respects
invalid, insufficient, fraudulent or forged; (c) payment by such Issuing Bank
against presentation of documents that do not comply with the terms of a Letter
of Credit, including failure of any documents to bear any reference or adequate
reference to the


                               Credit Agreement

Letter of Credit; or (d) any other circumstances whatsoever in making or failing
to make payment under any Letter of Credit, except that the relevant Borrower
shall have a claim against such Issuing Bank, and such Issuing Bank shall be
liable to such Borrower, to the extent of any direct, but not consequential,
damages suffered by such Borrower that such Borrower proves were caused by (i)
such Issuing Bank's willful misconduct or gross negligence in determining
whether documents presented under any Letter of Credit comply with the terms of
the Letter of Credit or (ii) such Issuing Bank's willful failure to make lawful
payment under a Letter of Credit after the presentation to it of a draft and
certificates strictly complying with the terms and conditions of the Letter of
Credit.  In furtherance and not in limitation of the foregoing, such Issuing
Bank may accept documents that appear on their face to be in order, without
responsibility for further investigation, regardless of any notice or
information to the contrary.

inquire as to the creditworthiness of the Borrowers.

          Section 9.11.  WAIVER OF JURY TRIAL.  EACH OF THE OBLIGORS, THE AGENT,
THE LENDERS AND THE ISSUING BANKS HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL
BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT,

extension of credit (whether by means of an Advance or a Letter of Credit),
herein or pursuant hereto shall survive

shall be deemed to have waived, by reason of making any extension of credit
hereunder (whether by means of an Advance or a Letter of Credit), any Default or
Event of Default that may arise by reason of such representation or warranty
proving to have been false or misleading, notwithstanding that such Lender, such
Issuing Bank or the Agent may have had notice or knowledge or reason to believe
that such representation or warranty was false or misleading at the time such
extension of credit was made.

                            OFFICER & KEY EXECUTIVE

                                     1996
                                     ----



I.        Purpose of the Plan
          -------------------

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

II.       Eligibility in the Plan
          -----------------------

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

III.      Special Provisions and Considerations
          -------------------------------------

          Terra's incentive plan year coincides with the company's fiscal year.
          The Chief Executive Officer will establish the corporate financial
          goals, which are approved by the Board of Directors, which will be
          used to establish the 1996 incentive pool. Each officer and key
          executive participating in this plan will be assigned an index which
          establishes their target incentive as a percentage of year-end base
          salary. Each officer and key executive participating in this plan will
          also establish a set of individual goals or objectives, the importance
          of each is reflected in their weight which sums to one-hundred percent
          (100%).

          The Chief Executive Officer is responsible for approving each plan
          participant's individual goals or objectives and will reach mutual
          agreement with each participant on the full set of incentive goals as
          soon as possible in the 1996 fiscal year. Each plan participant must
          execute and periodically report on a goal document approved and signed
          by the Chief Executive Officer.

IV.       Funding the Officer and Key Executive Incentive Award Program
          -------------------------------------------------------------

          The funding for the officer and key executive incentive award pool is
          based on the accomplishment of Terra Industries Inc. approved income
          and return-on-equity objectives, which will fund the incentive pool.
          The income goal will receive fifty percent (50%) weight and the
          return-on-equity goal will receive fifty percent (50%) weight.

          The pool starts to fund at seventy-five percent (75%) when the
          company's composite performance reaches seventy-five percent (75%) and
          increases on a percentage basis where one-hundred percent (100%) of
          composite performance equals a one-hundred percent (100%) funding of
          the pool. Over-achievement is calculated in the same manner with the
          pool capped at two-hundred percent (200%) of plan attainment. The pool
          may be increased by up to twenty percent (20%) at the Chief Executive
          Officer's discretion. Overall, the pool cannot exceed 200% of target
          including the discretionary portion of the pool.

 V.       Basis of the Incentive Award
          ----------------------------

          The starting point in determining each participant's individual
          incentive award is the evaluation of the individual objectives. The
          participant's individual raw award is calculated by taking each
          participant's year-end salary, times their individual index and then
          adjusted by their individual performance. The sum of adjusted raw
          awards creates an adjusted raw pool which is then compared with the
          sum of the plan participant's year-end salary, times their index which
          is then adjusted by the corporation's composite performance. This
          adjusted raw pool is adjusted up or down to match the incentive pool.
          All participant incentives are paid from the incentive pool.

          The Chief Executive Officer has the discretion to adjust any
          individual's participation up or down to reflect unusual or unplanned
          events or to reflect the degree of difficulty of the goals. He may
          adjust amounts between plan participants and may add amounts from the
          discretionary part of the pool. The Chief Executive Officer may also
          choose to award less than the full amount of the pool.

VI.       Review, Revision and Modification of the Goals
          ----------------------------------------------

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

VII.      Payment of Award
          ----------------

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

          To be eligible for full payment, the officer or key executive must
          have been in the employ of Terra Industries Inc. or one of its
          subsidiaries January 1 of the incentive plan year and must be actively

FINANCIAL REVIEW

CONSOLIDATED RESULTS

Favorable market conditions and the October 1994 acquisition of Agricultural
Minerals and Chemicals Inc. (AMCI) contributed to record earnings in 1995. Net
income for 1995 increased to $159.5 million from $56.6 million in 1994 and $22.8
million in 1993 with per share earnings of $1.96, $0.78 and $0.33, respectively.
Revenues increased to $2.29 billion in 1995 from $1.67 billion in 1994 and $1.24
billion in 1993.

Net income in 1995 and 1994 was reduced by $4.3 million and $3.1 million, or
$0.05 and $0.04 per share, respectively, due to the write-off of deferred
financing fees in connection with the early retirement of debt. Additionally,
1994 results included a net gain of $3.4 million, or $0.05 per share, to
recognize the cumulative effect of a change in the method of accounting for
major maintenance costs and adoption of Statement of Financial Accounting
Standards (SFAS) 112, "Employers Accounting for Post-Employment Benefits."

FINANCIAL COMPARABILITY AND OVERVIEW

The Corporation's improved earnings reflect internal growth and acquisitions
which have increased its manufacturing and distribution capabilities. The
following acquisitions are included in operating results.

On October 20, 1994, the Corporation acquired the stock of AMCI, for $506
million in cash. Through the AMCI acquisition and subsequent open market
purchases, the Corporation (as the general partner) has an approximate 65%
ownership interest in ammonia production and upgrading facilities located in
Verdigris, Oklahoma and Blytheville, Arkansas. The acquisition also included a
methanol production facility located in Beaumont, Texas.

On September 15, 1994, the Corporation acquired a 34% interest in Royster-Clark,
Inc. for $12 million in cash. Royster-Clark is a 110-location distributor of
crop production products in the mid-Atlantic region with annual sales of
approximately $200 million.

On December 31, 1993, the Corporation purchased net assets of certain operations
of Asgrow Florida, Inc. (Terra Asgrow Florida), a distributor of crop production
products, for $39 million in cash. Terra Asgrow

                                                                  CONFIDENTIAL  
                                                                             3

Florida currently operates 15 distribution centers and is a supplier to the
vegetable, citrus and ornamental plant markets, primarily in Florida.

Effective March 31, 1993, for $19.9 million in cash plus an operating lease, the
Corporation acquired the rights to an ammonia production and upgrading facility
near Sarnia, Ontario and ownership interests in 32 farm service centers in
Ontario, New Brunswick and Nova Scotia. Thirty of the farm service centers are
50% owned and two are 100% owned.

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 production products, 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.

Prices for nitrogen products are influenced by the world supply and demand
balance for ammonia and nitrogen-based products. 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.

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
for 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, potential legislation, the
willingness of regulatory agencies to grant waivers, and the availability and
use of alternative oxygenates, principally ethyl tertiary butyl ether (ETBE),
which is manufactured from ethanol.

With the acquisition of AMCI, the Corporation increased its annual production
capacity for methanol from 40 million to 320 million gallons. Approximately 45%
of the Corporation's production capacity is subject to a
<PAGE>
 
                                                                   CONFIDENTIAL
                                                                              4

methanol hedging agreement (the Methanol Hedging Agreement) (see Note 12 to the
Consolidated Financial Statements) which will affect margins on this portion of
the Corporation's methanol production through December 31, 1997 should average
methanol prices exceed average natural gas prices by certain amounts.

The number of acres planted and types of crops planted are influenced by
government programs designed to manage carryover stocks and commodity prices of
certain crops. Due to the higher quantities of crop production products 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. With worldwide grain stocks
at a record low and the government conservation reserve program beginning to
expire, planted acreage is expected to increase in 1996. Corn acreage in the
U.S. is estimated to increase to 80.6 million acres from 71.4 million in 1995.
Planted cotton acreage is estimated to decrease to 15.5 million from 16.8
million acres.

Weather can have a significant effect on operations. Weather conditions that
delay or intermittently disrupt field work during the planting and growing
season may result in fewer than normal crop production products 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 production
products purchased from the Corporation. During 1995 planting conditions were
unfavorable due to wet weather in many areas of the U.S. causing a reduction in
planted acres and use of certain crop production products.

Reliable sources for supply of crop production products 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 1996.

The principal raw material used to produce manufactured nitrogen products and
methanol is natural gas. Natural gas costs comprise almost 50% of the total
costs and expenses associated with nitrogen production and in excess of 50% of
the total costs and expenses associated with methanol. The Corporation's natural
gas procurement policy is to effectively fix or cap the price of approximately
40% to 80% of its natural gas
<PAGE>
 
                                                                   CONFIDENTIAL 
                                                                              5

requirements for a 12-month period through various supply contracts, financial
derivatives and other forward pricing techniques. Depending on market
conditions, the Corporation may also effectively fix or cap the price of natural
gas for longer periods of time. The Corporation believes that there is
sufficient supply to allow stable 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. At December 31, 1995, the
Corporation had natural gas contracts covering 78%, 46% and 31% of its natural
gas requirements for 1996, 1997 and 1998, respectively.

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 1996 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.

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, (c) changes in interest rates and (d) the effect of methanol prices
relative to natural gas prices. See Note 12 to the Consolidated Financial
Statements for information on the use of derivative financial instruments.

RESULTS OF OPERATIONS
 1995 COMPARED WITH 1994

CONSOLIDATED RESULTS

The Corporation reported net income of $159.5 million, or $1.96 per share, on
revenues of $2.29 billion in 1995 compared with net income of $56.6 million, or
$0.78 per share, on revenues of $1.67 billion in 1994. Results for 1995 include
a full year's effect of the AMCI acquisition which took place on October 20,
1994. The effect of including a full year of operations of the acquired business
increased 1995 revenues by $433 million and net income by $60 million. Other
significant factors that contributed to a successful 1995 were continued growth
in the Distribution segment despite a reduction in planted acres, a 24% increase
in nitrogen prices and natural gas costs which averaged 15% less than the prior
year. 1995's results were also achieved despite the effect of methanol prices
which declined significantly in 1995.

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 those
operations directly related to wholesale sales of nitrogen products from the
Corporation's ammonia manufacturing and upgrading facilities. The Methanol
segment represents wholesale sales of methanol from the Corporation's two
methanol manufacturing facilities.

The unaudited, pro forma results of operations have been prepared to give
effect to the Corporation's (i) acquisition of AMCI, (ii) issuance of 9.7
million Common Shares, and (iii) borrowing under a credit agreement entered
into in connection with the acquisition, assuming that all such transactions
had occurred on January 1, 1994. The pro forma financial data is presented for
informational purposes only and is not necessarily indicative of the results
that actually would have been obtained if the transactions had occurred on
January 1, 1994. In addition, the pro forma results are not intended to be a
projection of future operating results or trends.

DISTRIBUTION

Distribution revenues were $1.50 billion in 1995 compared with $1.32 billion in
1994, an increase of 13%. Higher volumes and the expansion of the retail
distribution network contributed to increased sales despite wet weather during
the spring planting season and a reduction in planted acres. Same store sales
increased by approximately 7%. About $100 million of the 1995 sales growth
consisted of increased retail chemical sales including sales of Terra's own
brand of Riverside products. Riverside product sales increased by $19 million.
Distributed fertilizer sales increased $62 million. Seed and other sales and
services increased by $17 million.

Operating income for the Distribution business was $41.2 million in 1995
compared with $33.8 million in 1994. Overall gross profit increased by
approximately $50 million. Increased sales volumes added
<PAGE>
 
                                                                   CONFIDENTIAL
                                                                              8

approximately $30 million in gross profits while higher margin grower and
Riverside brand sales accounted for the remainder. Selling, general and
administrative expenses increased $42.6 million. An estimated 60%, or $25
million, of the expense increase relates to expansion of the Distribution
business. The remaining increase of $17 million includes increased marketing
and promotional spending, an increase in bad debt experience from 1994 and
inflationary cost increases.

NITROGEN PRODUCTS

Nitrogen Products revenues were $635 million in 1995 compared with $297 million
in 1994. The increase reflects the inclusion in the Corporation's Consolidated
Financial Statements of a full year of results from the Verdigris, Oklahoma and
Blytheville, Arkansas ammonia plants acquired in October 1994. The acquired
plants raised the Corporation's total production capacity from 1.3 million to
2.7 million gross tons of ammonia. Revenues also increased as a result of an
approximate 24% increase in prices.

Operating income for the Nitrogen Products business was $264 million in 1995
compared with $48 million in 1994. The increase reflects a full year of results
from the Verdigris, Oklahoma and Blytheville, Arkansas plants as well as the
effect of the approximate 24% increase in prices. Additionally, natural gas
costs decreased by approximately 15% compared with 1994 costs. The increase in
operating margin to 42% in 1995 from 16% in 1994 primarily reflects the change
in nitrogen prices and natural gas costs.

The Corporation's Port Neal facility was extensively damaged as a result of an
explosion on December 13, 1994. The facility was insured for property damage,
business interruption and third party liability claims. Revenues and operating
income in 1995 include the estimated lost profits which are recoverable under
the Corporation's insurance policy. The Corporation received interim payments to
cover its property damage, business interruption and third party claims and
expects to receive additional payments. In December 1995, ammonia production
resumed at the Port Neal facility. Upon final settlement of the property claim,
the Corporation expects to record a substantial nonrecurring gain, representing
the difference between the final property settlement and the carrying value of
the facility at the time of the explosion.

METHANOL

Methanol revenues were $195 million in 1995 compared with $70 million in 1994.
The increase reflects the inclusion in the Corporation's Consolidated Financial
Statements of a full year of results from the Beaumont, Texas methanol facility,
which was acquired in October 1994, and a full year of operation of the
Corporation's Woodward, Oklahoma plant, whose capacity was partially converted
from ammonia to methanol production in April 1994. The production capacities of
the two plants are 280 million gallons per year and 40 million gallons per year,
respectively.

Operating income totaled $77 million in 1995 compared with $43 million in 1994.
Prices for methanol rose rapidly in the fourth quarter of 1994 and then fell
sharply in February, March and April of 1995. The reduction in operating margin
from 61% in 1994 to 40% in 1995 primarily reflects the decline in selling
prices. The Corporation expects methanol prices to continue within their
"normal" historical range of $0.30 to $0.60 per gallon. Gross profits were $82.6
million in 1995 compared with $44.8 million in 1994. Selling, general and
administrative expenses were $5.5 million in 1995 compared with $2.1 million in
1994.

In October 1994, the Corporation entered into the Methanol Hedging Agreement.
Under the Methanol Hedging Agreement the Corporation is required to make
payments should the market price of methanol increase in relation to the cost of
natural gas for defined quantities of production. As a result of the unusually
high methanol prices at the end of 1994, $15.9 million was accrued as payable
under the Methanol Hedging Agreement. This accrual was reversed in 1995 as
prices declined to lower levels. The effect of the accrual and its subsequent
reversal was to decrease 1994 revenues and operating income by $15.9 million and
increase 1995 revenues and operating income by a like amount. No amounts have
been paid or are presently accrued as of December 31, 1995 pursuant to the
Methanol Hedging Agreement.

OTHER OPERATING EXPENSE - NET

Other operating expense was $4.4 million in 1995 compared with $9.5 million in
1994. Other operating expense consists of corporate level expenses, including
certain insurance coverages, corporate finance fees and other costs.

INTEREST EXPENSE - NET

Interest expense, net of interest income, totaled $51.1 million in 1995 compared
with $16.5 million in 1994. The increase was principally the result of higher
interest expense due to additional debt in connection with the acquisition of
AMCI.

MINORITY INTEREST

Minority interest, representing third party unitholder interest in the earnings
of Terra Nitrogen Company, L.P. (TNCLP), increased to $47.2 million in 1995
compared with $8.8 million in 1994. The increase was due to the inclusion of a
full year of operations of TNCLP in the Corporation's Consolidated Financial
Statements and the effect of higher nitrogen prices on TNCLP's results.

INCOME TAXES

Income tax provision was recorded at an effective rate of 41.3% for 1995
compared with 37.5% for 1994. The increased rate results primarily from the
amortization of goodwill from the AMCI acquisition which is not deductible for
tax purposes.

RESULTS OF OPERATIONS

for Terra Asgrow Florida and AMCI subsequent to its acquisition on October 20,
1994. These acquisitions added approximately $190 million to revenue and $21
million to operating income. Excluding the impact of these acquisitions,
revenues increased $240 million, or 19%, over 1993 and operating income
increased $12 million, or 46%.

DISTRIBUTION

Distribution revenues of $1.32 billion in 1994, increased $299 million, or 29%,
over 1993 results. Approximately $198 million of the growth relates to a 30%
increase in crop protection products sales resulting principally from the
acquisition of Terra Asgrow Florida (which added approximately $80 million),
acquisition of new locations and higher planted acreage. Growth in the
Corporation's own brand of Riverside products accounted for $22 million of the
increase. Distributed fertilizer sales increased $55 million, and seed and other
sales and services increased $45 million as a result of higher planted acreage
in 1994 and favorable weather conditions. 1993 revenues were negatively impacted
by the flooding and wet weather conditions in the central U.S. which reduced
planted acres and crop production product application rates.

Operating income for the Distribution business was $33.8 million in 1994
compared with $16.9 million in 1993. Gross margin percentages remained
relatively constant and overall gross profit increased approximately $46.5
million. Selling, general and administrative expenses increased $24.4 million.
This includes an increase in compensation costs of $17.4 million due to normal
wage increases and additional personnel resulting from expansion activities. In
addition, equipment leasing and facilities costs increased $4.2 million.

NITROGEN PRODUCTS

Nitrogen Products revenues increased 30% to $296.6 million in 1994 from $228.9
million in 1993. The acquisition of AMCI on October 20, 1994, accounted for
$60.4 million of revenue growth. Excluding the impact of the acquisition,
revenues increased $7.3 million, or 3.2%. 1994 revenues were reduced by
approximately $10 million due to the April 1994 conversion of 30% of the
capacity of the Corporation's Woodward, Oklahoma plant from ammonia to methanol
production.

Operating income for the Nitrogen Products business was $48.4 million in 1994
compared with $28.7 million in 1993. The acquisition of AMCI contributed $18.9
million to the increase in operating income. Excluding the AMCI acquisition and
a $7 million non-recurring charge described below, operating earnings increased
$7.8 million due to price increases of $15.3 million, partially offset by higher
natural gas costs and the conversion of ammonia capacity to methanol.

On December 13, 1994, the Corporation's Port Neal facility in Iowa was
extensively damaged as a result of an explosion. The Corporation recognized a $7
million charge against 1994 earnings to cover its aggregate expected
unrecoverable costs associated with the incident, including deductibles and
other uninsured costs.

METHANOL

In April 1994, about 30% of the production capacity of the Woodward, Oklahoma
plant was converted from the production of ammonia to methanol. Additionally, on
October 20, 1994, through the acquisition of AMCI, the Corporation acquired a
methanol production facility in Beaumont, Texas. The Corporation had no methanol
operations in 1993.

Methanol revenues were $70.3 million and operating income for the Methanol
business was $42.7 million in 1994. Gross profit on methanol was $44.8 million
and selling, general and administrative expenses were $2.1 million.

Under the Methanol Hedging Agreement, $15.9 million was expensed in 1994 and
reflected as a payable at December 31, 1994.

OTHER OPERATING EXPENSE - NET

Other operating expense was $9.5 million in 1994 compared with $3.7 million in
1993. The increase over 1993 was primarily the result of a non-recurring 1993
gain of $4.2 million on the settlement of a dispute with a vendor.

INTEREST EXPENSE - NET

Interest expense, net of interest income, totaled $16.5 million in 1994 compared
with $9.7 million in 1993. The increase was principally the result of higher
interest expense due to the assumption of $175 million of long-term debt and the
issuance of $270 million of additional debt, both in connection with the
acquisition of AMCI.

INCOME TAXES

The income tax provision increased in 1994 due to higher pretax book income and
the utilization during 1993 of previously unrecognized capital loss
carryforwards.

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 on TNCLP's Senior Preference Units (SPUs), and make
capital expenditures and acquisitions. Its principal sources of funds will be
cash flow from operations and borrowings under its current bank facility.
Additionally, the Corporation expects to receive insurance reimbursements
related to its Port Neal casualty loss. The Corporation believes that cash from
operations and available financing sources will be sufficient to meet
anticipated cash requirements.

During 1995, the Corporation utilized cash from operations to retire long-term
debt, invest in additional farm service centers and make manufacturing
improvements. Additionally, the Corporation used the proceeds of a $200 million
note issue to purchase TNCLP units on the open market and pay down bank term
debt. Proceeds from the issuance of preferred stock in a subsidiary and the
interim payments from the Corporation's insurance carriers have been utilized to
fund certain expenditures related to the Corporation's Port Neal casualty loss.

Net cash provided by operating activities was $243 million in 1995 compared with
$168 million in 1994. The increase was principally due to the higher cash
earnings attributable to a full year of operations of the

                                                                   CONFIDENTIAL 
                                                                             14

Corporation's acquired businesses and the impact of higher nitrogen prices
offset by spending related to the Port Neal casualty loss in excess of interim
payments from insurers.

In 1995 investing activities totaled $95 million. Spending on the construction
of the Corporation's Port Neal facility totaled $133 million of which $128
million was offset by insurance proceeds. Acquisitions, consisting principally
of retail distribution locations, totaled $22 million. In addition, purchases of
property, plant and equipment of $44 million in 1995 consisted of expansion of
existing service centers, additions and routine replacements of distribution
equipment, and improvements and replacements at manufacturing facilities. The
Corporation expects 1996 capital spending, exclusive of expenditures related to
the Port Neal casualty and the acquisition of retail distribution locations, to
be approximately $50 million. During 1996, the Corporation expects to make
additional expenditures related to the Port Neal casualty loss. The Corporation
is in discussions with its insurers and expects that additional proceeds will be
received in connection with the insurance claim.

On March 27, 1995, the Corporation announced its offer to purchase all 7.6
million of the publicly held SPUs representing a 39.8% partnership interest in
the Corporations's acquired nitrogen business. On May 11, 1995, the Board of
Directors of the Corporation withdrew its offer and approved an open market
purchase program pursuant to which the Corporation may purchase up to five
million SPUs from time to time at prices and in quantities determined by the
Corporation's management. As of December 31, 1995, 974,900 SPUs had been
acquired by the Corporation for $28.8 million. The Corporation will finance any
further purchases of SPUs with available cash or debt.

The Corporation issued $200 million of 10.5% Senior Notes during 1995 used
principally to prepay outstanding long-term bank debt. The Corporation made
additional prepayments on the bank term loans in the fourth quarter made
possible due to strong cash flows provided by operating activities. The
Corporation's debt, including current maturities, as a percentage of total
capital (excluding minority interest) was reduced to 42% at December 31, 1995
compared with 57% at December 31, 1994.

During 1995, the Corporation transferred the Port Neal facility to Port Neal
Holdings Corp. (PNH). PNH was structured to finance and complete construction of
the Port Neal facility through its wholly owned subsidiary, Port Neal
Corporation (PNC). PNH issued, to unrelated third parties, $25.0 million of non-
convertible

                                                                             15

preferred stock. The preferred stock represents 25% of the voting rights of PNH
and accrues dividends commensurate with market interest rates.

During 1995, the Corporation distributed $36.8 million to minority unitholders
and paid quarterly dividends aggregating $8.7 million on the Corporation's
Common Shares.

Year-end accounts receivable and inventory balances increased by $22 million and
$34 million, respectively. The increases were partially offset by a $22 million
increase in accounts payable. The increases were attributable to higher fourth
quarter sales and off-season purchasing to obtain discounts and to meet
anticipated demand. The ratio of current assets to current liabilities increased
to 1.7 to 1 at December 31, 1995 from 1.6 to 1 at December 31, 1994.

Cash generated from operations during 1996 is expected to be adequate to meet
normal business requirements and service debt. Cash balances at December 31,
1995 were $138.7 million of which $8.9 million was used to collateralize letters
of credit supporting recorded liabilities. The Corporation's bank facility
contains certain restrictions, which are described in Notes 8 and 10.
Additionally, the public holders of TNCLP's SPUs representing a 35% interest in
the Corporation's Blytheville, Arkansas and Verdigris, Oklahoma ammonia plants
are entitled to receive a minimum quarterly distribution of $0.605 per unit, or
$4.0 million, plus arrearages before any distribution to the Corporation's
Common Units. At December 31, 1995 there were no distributions in arrears.

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 Canadian subsidiary are translated using average
currency exchange rates during the period while assets and liabilities are
translated using current rates.  Resulting translation adjustments are recorded
as currency translation adjustments in stockholders' equity.

Cash and short-term investments:

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

Inventories:

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

Property, plant and equipment:

Expenditures for plant and equipment additions, replacements and major
improvements are capitalized.  Related depreciation is charged to expense on a
straight-line basis over estimated useful lives ranging from 15 to 20 years for
buildings and 3 to 15 years for plant and equipment.  Maintenance and repair
costs are expensed as incurred.

Excess of costs over net assets of acquired business:

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.

Accounting standards not adopted:

In March 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards (SFAS) 121, "Accounting for the Impairment of
Long-Lived Assets."  SFAS 121 required that long-lived assets and certain
identifiable intangibles to be held and used by an entity be reviewed for
impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable.  The Corporation will adopt
SFAS 121 as required in 1996 but does not expect that any adjustments will be
required to the holding value of long-lived assets.

In October 1995, the  Financial Accounting Standards Board issued SFAS 123,
"Accounting for Stock Based Compensation."  Beginning in 1996, SFAS 123 requires
expanded disclosures of stock-based compensation arrangements with employees and
encourages, but does not require, the recognition of employee compensation
expense related to stock compensation based on the fair value of the equity
instrument granted.  Companies that do not adopt the fair value recognition
provisions of SFAS 123 and continue to follow the existing APB
<PAGE>
 
                                                                    CONFIDENTIAL
                                                                              21

Opinion 25 rules to recognize and measure compensation, will be required to
disclose the pro forma amounts of net income and earnings per share that would
have been reported had the company elected to follow the fair value recognition
of SFAS 123. Management will determine in 1996 the Corporation's approach to
SFAS 123. The impact on the Corporation's financial position and results of
operations is not expected to be material.

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.

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.

Reclassifications:

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

Per-share results:

Earnings-per-share data are based on the weighted average number of Common
Shares outstanding.  The dilutive effect of the Corporation's outstanding
restricted shares, stock options and convertible debentures was not significant.

2.  ACQUISITIONS

On October 20, 1994, the Corporation acquired AMCI for $506 million in cash.
AMCI, through its subsidiaries manufactures nitrogen-based fertilizers and
industrial use products and methanol.  The subsidiaries controlled by the
Corporation as a result of the AMCI acquisition include Terra Nitrogen
Corporation (TNC), Beaumont Methanol, Limited Partnership (BMLP) and Terra
Nitrogen Company, L.P. (TNCLP).  As a result of the acquisition and subsequent
open market purchases (see Note 10 - Long-Term Debt) the Corporation and its
subsidiaries have approximately a 65 percent ownership interest in TNCLP,
formerly Agricultural Minerals Company, L.P., which operates nitrogen products
manufacturing facilities in Verdigris, Oklahoma and Blytheville, Arkansas
through an operating partnership, Terra Nitrogen, Limited Partnership (TNLP),
formerly Agricultural Minerals, Limited Partnership.  Terra Methanol Corporation
(TMC) is the general partner of BMLP which operates a methanol production
facility in Beaumont, Texas. The acquisition has been accounted for using the
purchase method of accounting.

To finance the acquisition of AMCI, the Corporation issued 9.7 million Common
Shares for aggregate net proceeds of approximately $113 million, entered into
credit arrangements to issue $310 million of long-term debt, and refinanced
certain bank debt and credit lines of the Corporation, AMCI and AMCI's
subsidiaries aggregating $260 million of which $152 million in borrowings were
outstanding.  As a result of the acquisition of AMCI, the Corporation also
assumed AMCI's obligations including its 10.75% Senior Notes due 2003 (see Note
10 - Long-Term Debt).

On September 15, 1994, the Corporation acquired a 34% interest in Royster-Clark,
Inc. for $12 million in cash.  Royster-Clark is a 110-location distributor of
crop input and protection products in the mid-Atlantic region.

On December 31, 1993, Terra International, Inc. purchased net assets of certain
operations of Asgrow Florida Company, Inc. (Terra Asgrow Florida), a distributor
of fertilizer, chemicals and seed, for $39 million.  Terra Asgrow Florida
currently operates 15 distribution centers and is a supplier to the vegetable,
citrus and ornamental plant markets, mostly in Florida.

On April 8, 1993, a wholly owned subsidiary of the Corporation, Terra
International (Canada) Inc. (Terra Canada) acquired rights to an anhydrous
ammonia manufacturing plant and related upgrading facilities (the nitrogen
plant) located at Courtright, Ontario effective as of March 31, 1993.  In
addition, Terra Canada purchased working capital associated with the nitrogen
plant and interest in 32 farm service centers operating under the trademark,
Agromart(TM).  All but two of the Agromarts(TM) are owned by corporations in
which Terra Canada has a 50% interest, and the remaining 50% interests are owned
by local management and other investors.  The remaining two Agromarts(TM) are
wholly owned by Terra Canada.  The amount paid in connection with the
transaction was approximately $73 million (Cdn) of which approximately $47
million (Cdn) was provided through lease financing and the remainder was funded
by a working capital line of credit and cash.

Operating results of the acquired businesses subsequent to the respective dates
of each acquisition are included in the Consolidated Statements of Income.  The

3.  ACCOUNTING CHANGES

Coincident with the 1994 acquisition of AMCI (see Note 2 - Acquisitions), the
Corporation changed its method of accounting for major maintenance turnarounds
at manufacturing facilities and recorded a $4.2 million credit, net of income
taxes of $2.7 million, as the cumulative effect at January 1, 1994 of the change
in accounting principle.  Excluding the cumulative effect, this change increased
net income for 1994 by approximately $1.0 million, or $0.01 per share.  Under
the new accounting principle the Corporation defers the cost of turnarounds when
incurred and charges the costs to production ratably over the period until the
next scheduled turnaround.  Previously, estimated costs of turnarounds were
charged to product costs over the period preceding each scheduled major
maintenance, generally two years.  The change was made to charge turnaround
costs to production over the period most clearly benefited by the turnaround.

In 1994, the Corporation adopted SFAS 112, "Employers Accounting for Post-
Employment Benefits."  This change required the Corporation to recognize future
liabilities of $0.8 million, net of income taxes of $0.5 million, for benefits
to disabled employees.  Prior to the adoption of SFAS 112, the Corporation
recognized such expenses in the period the benefits were paid.

4.  RELATIONSHIP WITH MAJORITY STOCKHOLDER

Minorco, through its beneficial ownership of Common Shares, owns approximately
53 percent of the equity of the Corporation.  The Corporation procures certain
insurance coverages for Minorco and related companies, subleases office space to
Minorco, and shares the cost of certain employees of both organizations.
Payments to the Corporation in settlement of these services are made on an
ongoing basis and totaled $1.0 million, $0.9 million and $1.0 million in 1995,
1994 and 1993, respectively.

7.  PORT NEAL CASUALTY

On December 13, 1994, the Corporation's Port Neal facility in Iowa was
extensively damaged as a result of an explosion.  There were four employee
fatalities plus injuries or damages to other people and property.  Insurance was
in force to cover damage to the Corporation's property, business interruption
and third party liability claims.  A $7 million pretax charge was recorded in
1994 for expected uninsured costs associated with the incident, including
deductibles.  As of December 31, 1995, the Corporation had received interim
payments of $175.3 million on its claim.  The Corporation is in discussions with
its insurers as to additional insurance proceeds which the Corporation believes
it should be entitled.  Estimated lost profits recoverable under the business
interruption policy are being included in income.  Insurance proceeds received
under the Corporation's property damage claim are being deferred pending final
settlement of the claim.  The Corporation has invested additional funds for
other enhancements and improvements at the Port Neal facility.

The Corporation expects to record a substantial non-recurring gain, representing
the difference between the property insurance settlement on the Port Neal
facility with the Corporation's insurers and the carrying value of the facility
at the time of the explosion.  The amount of the gain will be dependent on final
construction, clean-up expenditures and the settlement reached with the
Corporation's insurance carriers.  As of December 31, 1995, $80.3 million has
been recorded as a deferred gain and is included in other liabilities.

During 1995, the Corporation amended its credit agreement to provide revolving
credit facilities of up to $375 million for domestic seasonal working capital
needs and other corporate purposes.  The Corporation also has a $25.7 million
($35 million Cdn) revolving credit facility used to provide for working capital
needs for its Canadian operations.  There was $26.0 million outstanding at
December 31, 1995 under the domestic facility and no outstanding borrowing under
the Canadian facility.  Interest on borrowings under these lines is charged at
current market rates.

Under the amended credit agreement, the Corporation has agreed, among other
things, to maintain certain financial covenants including minimum net worth and
interest coverage ratios, 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 domestic revolving credit facilities expire December 31, 2000.  A
commitment fee is charged on the unused portion of the facilities under the
credit agreement, currently 1/4 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 the
personal property of the former AMCI subsidiaries.

Under the Canadian facility, the Corporation has agreed, among other things, to
maintain certain levels of working capital and net worth, adhere to maximum debt
leverage limitations and restrict payments to the Corporation from operating
subsidiaries.  The Canadian facility expires October 17, 1996 and is renewable
every 120 days for a 360-day term.  A commitment fee of 1/8 percent is paid on
the facility.

principal amount out of the proceeds of one or more public offerings of equity
securities at a redemption price of 110% of their principal amount, plus accrued
interest.  The 10.75% Senior Notes Indenture contains restrictions similar to
those in the 10.5% Senior Notes Indenture.

The Corporation entered into a secured credit agreement with financial
institutions to provide Bank Term Loans (Loans) to finance a portion of the 1994
acquisition of AMCI and to refinance existing debt of $40 million at the
Corporation and $35 million at TNLP.  The $35 million TNLP debt was repaid in
May 1995.  In December 1995, the remaining Loans outstanding were converted into
advances under an amended credit agreement providing up to $375 million in
revolving credit described more fully in Note 8 - Debt Due Within One Year.

The $30 million unsecured 8.48% Senior Notes require annual principal payments
commencing November 1, 1999 through May 1, 2005.  The notes include covenants

located near Sarnia, Ontario.  The agreement is for a four-year term requiring
annual lease payments of approximately $4.0 million (Cdn).  Terra Canada has an
option to purchase the nitrogen plant during the term of the lease and at
expiration for approximately $72 million (Cdn).  If, at the end of the lease
term, Terra Canada elects not to exercise its purchase option, the Corporation
must pay to the lessor approximately $61 million (Cdn) subject to reimbursement
based on the proceeds realized upon the sale of the nitrogen plant by the
lessor.  Terra Canada has entered into certain agreements in order to convert
its obligations with respect to the nitrogen plant set forth above from Canadian
dollar and fixed rental obligations to U.S. dollar and variable rental
obligations based on interest rate changes tied to LIBOR.

Total rental expense under all leases, including short-term cancelable operating
leases, was approximately $46.8 million, $37.3 million and $24.7 million for the
years ended December 31, 1995, 1994 and 1993, 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
percent or more of any company liable for such benefits as of certain specified
dates becomes liable for such benefits if the company directly liable is unable
to pay them.  As a result, if the purchaser becomes unable to pay its retiree
medical obligations assumed pursuant to the sale, the Corporation may have to
pay such amount.  The Corporation has estimated that the present value of
liabilities for which it retains contingent responsibility approximates $9
million at December 31, 1995.  In the event the Corporation would be required to
assume this liability, mineral reserves associated with the sold coal subsidiary
would revert to the Corporation.

During March 1994, the Corporation entered into an agreement to sell its
receivables.  Under this agreement, which expires March 31, 1996, the
Corporation may sell with limited recourse an undivided interest in a designated
pool of its accounts receivable and receive up to $50 million in proceeds.
Undivided interests in new receivables may be sold as collections reduce
previously sold interests.  The undivided interests are sold at a discount that
is included in selling, general and administrative expense in the Consolidated
Statements of Income.  At December 31, 1995, the proceeds of the uncollected
balance of receivables sold totaled $50 million.  The Corporation retains
collection and administrative responsibility on the participating interests
sold.

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 either the results of operations,
financial position or net cash flows of the Corporation.

12. DERIVATIVE FINANCIAL INSTRUMENTS

The Corporation manages four categories of risk using derivative financial
instruments:  (a) foreign currency fluctuations (b) changes in natural gas
supply prices (c) interest rate fluctuations and (d) the effect of fluctuations
in methanol prices relative to natural gas prices.

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.  Gains and
losses on these contracts are deferred and included as a component of the
related transaction.  The contracts had no recorded value and a fair value of
$0.7 million at December 31, 1995.  The contracts had no recorded value and
would have cost $0.8 million to liquidate at December 31, 1994.  Fair value of
foreign exchange contracts is based on quotations received from a quotation
service and computations prepared by the Corporation.  The following describes
the specific areas of risk being managed:

     (a)  Canadian dollar lease commitments under the Corporation's Canadian
          nitrogen plant lease, aggregating $78.0 million (Cdn), which extend
          through April 1997, have been hedged (converted into U.S. dollar
          obligations) with forward exchange and basis swap contracts.

     (b)  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 to cover a
          portion of its estimated net Canadian dollar requirements over a
          twelve-month period. As of December 31, 1995, the existing forward
          contracts represented approximately 30% of anticipated net 1996
          Canadian dollar requirements of approximately $46 million (Cdn).

NATURAL GAS PRICES - Natural gas supplies to fill 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 fixes
prices for a portion of its natural gas requirements through the use of futures
contracts, swaps and options. These contracts are traded up to thirty-one months
forward and settlement dates are scheduled to coincide with gas purchases during
that future period.  A swap is a contract between the Corporation and a third
party to exchange cash based on a designated price, which price is referenced to
market natural gas prices or appropriate NYMEX futures contract prices.  Option
contracts give the holder the right to either own or sell a futures or swap
contract at a designated price.  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, 1995 and
1994:

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

Annual production requirements are 133,000 MMBtu.  Contracts were in place at
December 31, 1995 to cover 78% of 1996 natural gas requirements, 46% for 1997
and 31% for 1998.
<PAGE>
 
                                                                    CONFIDENTIAL

Gains and losses on settlement of these contracts and premium payments on option
contracts are credited or charged to manufacturing cost 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 and premium payments on option contracts of $11.4 million
and $7.7 million, respectively, relating to future periods have been deferred.

During 1995, natural gas hedging activities produced cost increases of
approximately $34.5 million, or 16%, of total natural gas purchases compared
with spot prices.  During 1994, natural gas hedging increased cost by
approximately $15.5 million, or 13%, of total natural gas purchases.

The Corporation has also limited the effect of natural gas price fluctuations
through the use of basis swaps. Such contracts require payments to the
Corporation for the amount, if any, that monthly published gas prices from the
source specified in the contract exceed the average of the daily settlement
prices for the last three scheduled trading days of NYMEX natural gas futures on
an adjusted basis as specified in the contract for the applicable determination
period, and vice versa.  As of December 31, 1995 and 1994, MMBtu's under such
contracts totaled 14.7 million and 0.5 million, respectively.

INTEREST RATE FLUCTUATIONS - The Corporation has limited the effect of interest
rate fluctuations for a portion of its floating rate obligations through the use
of interest rate collar agreements.  The agreements require payments to the
Corporation for the amount, if any, that interest costs, on a cumulative basis,
exceed 8.5% to 9.0% (LIBOR) and requires payments by the Corporation for the
amount that interest costs fall below 5.65% (LIBOR).  At December 31, 1995, the
Corporation had $161 million of obligations subject to variable interest rates.
The interest rate collar agreements, with a  notional amount of $160 million
(which declines over the remaining 2-year period), cover 99.4% of the variable
interest rate obligations at December 31, 1995.

The unamortized cost of the collar agreements is $0.7 million at December 31,
1995 and is carried in other assets in the Consolidated Statement of Financial
Position.  No payments are receivable or due under the agreements at December
31, 1995.  The cost to liquidate the collar agreement at December 31, 1995 would
be $1.7 million.

The Corporation has also entered into interest rate swap agreements to convert
$15 million of its fixed-rate, long-term borrowings to variable rates through
April 15, 2003.  For 1995, the net interest rate effect of the swap arrangements
totaled 1.8% effectively reducing the interest rate on its $30 million of 8.48%
Senior Notes to 7.58%.  For 1994, the net interest rate effect of the swap
arrangements totaled 2.2% effectively reducing the interest rate to 7.39%.
Additionally, the Corporation has entered into an interest rate swap agreement
to convert fixed U.S. dollar lease payments to variable rates based on LIBOR
through April 8, 1997.  At December 31, 1995, the notional amount of the swap
agreement was approximately $35.8 million and would cost $0.2 million to
liquidate.


METHANOL PRICES - The Corporation entered into a methanol hedging agreement (the
Methanol Hedging Agreement) effective October 1994.  Pursuant to the agreement,
the Corporation received $4 million in cash and agreed to make payments to the
extent that average methanol prices exceed the sum of $0.65 per gallon plus
0.113 times the average spot price index in cents per MMBtu for natural gas
during the periods October 20, 1994 to December 31, 1995, calendar year 1996,
and calendar year 1997.  The amount due, if any, is dependent upon average
methanol and natural gas prices during each of the periods.  Payments are due
five days after the end of each period.  The quantities subject to the agreement
for each of these periods are 155.5 million, 140 million and 130 million
gallons, respectively.  The Corporation's methanol production facilities have a
production capacity of 320 million gallons of methanol per year.

                                                                    CONFIDENTIAL

The $4 million received pursuant to the Methanol Hedging Agreement is being
recognized as income over the term of the agreement.  No amounts have been paid
or are presently accrued under the terms of the agreement. The estimated fair
value of the agreement, representing the amount that the Corporation would
expect to pay at December 31, 1995 to liquidate the agreement for its remaining
term, is less than $1 million.

13. FINANCIAL INSTRUMENTS AND CONCENTRATIONS OF CREDIT RISK

The following table presents the carrying amounts and estimated fair values of
the Corporation's financial instruments at December 31, 1995 and 1994.  SFAS
107, "Disclosures about Fair Value of Financial Instruments," defines the fair
value of a financial instrument as the amount at which the instrument could be
exchanged in a current transaction between willing parties.

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

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

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 comparisons with similar companies whose
shares are publicly traded when available.

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.

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

FINANCIAL INSTRUMENTS - At December 31, 1995, the Corporation had letters of
credit outstanding totaling $29.5 million, guaranteeing various insurance and
financing activities.  Short-term investments of $8.9 million and $9.6 million
at December 31, 1995 and 1994, respectively, are restricted to collateralize
certain of the letters of credit.

14. STOCKHOLDERS' EQUITY

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

In 1995, the Corporation issued 54,400 restricted shares and 38,400 shares were
canceled under the 1992 Stock Incentive Plan (the 1992 Plan).  No restricted
shares vested during 1995.  At December 31, 1995, 388,000 of the issued unvested
shares remain outstanding.  Under terms of the issuance, vesting of stock
granted is contingent upon the attainment, prior to February 2001, of pre-
established market price objectives for the Corporation's shares.  During 1994,
229,218 shares issued under the 1992 Plan were vested with plan participants and
139,282 shares were canceled.  In 1994, the Corporation issued an additional
372,000 restricted Common Shares under the 1992 Plan to certain key employees of
the Corporation.  In 1991, the Corporation issued 33,300 restricted Common
Shares under its 1987 Stock Incentive Plan.  The agreement restricts the shares
to vesting in equal annual installments over five years.  The shares issued are
entitled to normal voting rights and earn dividends as declared during the
performance periods.  Compensation expenses are accrued on ratable bases through
the performance periods.

On July 6, 1993, the outstanding HBMS Special Exchangeable Non-Voting Shares
(HBMS Special Shares) were each automatically exchanged for one Common Share of
the Corporation.  The Corporation has authorized 16,500,000 Trust Shares for
issuance and none are outstanding at December 31, 1995.

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

At December 31, 1995, 2.6 million Common Shares were reserved for issuance upon
award of restricted shares and exercise of employee stock options.

In September 1995, the Corporation transferred its Port Neal facility (including
improvements then in progress) and $1.3 million in cash to Port Neal Holdings
Corp. (PNH) and issued, to unrelated third parties, $25 million of non-
convertible preferred stock.  As a result, the Corporation indirectly owns 100%
of the common stock of PNH (representing 75% of the voting rights of PNH).  PNH
was structured to finance and complete the construction of the Port Neal
facility through its wholly owned subsidiary, Port Neal Corporation (PNC). The
preferred stock represents 25% of the voting rights of PNH and accrues dividends
at a floating rate commensurate with market interest rates.  The Corporation
accounts for the preferred stock as a minority

were entered into with PNH and/or PNC including intercompany debt obligations
and lease arrangements.

15. STOCK OPTIONS

The Corporation's 1992 Stock Incentive Plan authorized granting key employees
options to purchase Common Shares at not less than fair market value on the date
of grant and also authorizes the award of performance units and restricted
shares.  The Corporation's 1983 Stock Option Plan and 1987 Stock Incentive Plan
authorized granting key employees similar options to purchase Common Shares.  No
further options may be granted under the 1983 and 1987 Plans.  Awards to a
maximum of 2.5 million Common Shares may be granted under the 1992 Plan.
Options generally may not be exercised prior to one year or more than ten years
from the date of grant.  At December 31, 1995, 1,226,982 Common Shares were
available for grant under the 1992 Plan.  A summary of activity under the 1992,
1987 and 1983 Plans follows:

16. 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:

The Corporation also sponsors a qualifying savings plan covering most full-time
employees.  Contributions made by participating employees are matched based on a
specified percentage of employee contributions to 6% of the employees' pay base.
The cost of the Corporation's matching contribution to the savings plan totaled
$3.7 million in 1995, $1.9 million in 1994 and $1.4 million in 1993.

17. 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.

benefits obligation included in the Corporation's Consolidated Statements of
Financial Position at December 31:

Remaining unutilized NOL carryforwards were approximately $12.5 million and $4.8
million at December 31, 1995 and 1994, respectively.  NOL carryforwards that
have not been utilized expire in 2005.  Alternative minimum tax (AMT) credits
were $13.4 million and $36.7 million at December 31, 1995 and 1994,
respectively.  AMT credits have an indefinite life.  The Corporation's capital
loss carryforwards totaled $11.5 million and $6.2 million at December 31, 1995

20. 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,
urea ammonium nitrate solution, 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.  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 information about the Corporation's industry segments:

21. AGREEMENTS OF LIMITED PARTNERSHIP

In accordance with the Agreement of Limited Partnership of TNCLP, quarterly
distributions to Unitholders and the General Partner are made in an amount equal
to 100% of its Available Cash, as defined, unless Available Cash is required to
fund a reserve amount.  TNCLP must fund and maintain a reserve of $18.5 million
to support Minimum Quarterly Distributions on the Senior Preference Units (the
Reserve Amount). Such Reserve Amount was fully funded at December 31, 1995.

During the period which commenced December 4, 1991, and not ending prior to
December 31, 1996 (the Preference Period), Senior Preference Units (SPUs) and
Common Units participate equally in distributions after each class of units has
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.  During the Preference Period,
distributions are subject to the rights of SPUs to receive the Minimum Quarterly
Distribution of $0.605 per unit plus any arrearages, before any other
distributions.  After such amounts have been paid, the Reserve Amount must be
funded before distributions to Common Unitholders.

On December 31, 1995 all Junior Preference Units were converted to SPUs.  After
the Preference Period the Senior Units will still be entitled to the Minimum
Quarterly Distribution, but will not participate with the Common Units in any
distributions above the Minimum Quarterly Distribution.

For a 90-day period after the end of the Preference Period, the holders of SPUs
will have the right, subject to fulfillment of certain stock exchange listing
requirements, to convert their SPUs into fully participating Common Units.

RESPONSIBILITY FOR FINANCIAL STATEMENTS


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

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

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

The Consolidated Financial Statements contained in this Annual Report have been
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
examinations of the Consolidated Financial Statements.

INDEPENDENT AUDITORS' REPORT


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



We have audited the accompanying consolidated statements of financial position
of Terra Industries Inc. and subsidiaries as of December 31, 1995 and 1994, 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, 1995.  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, 1995 and 1994, and the results of their operations
and their cash flows for each of the three years in the period ended December
31, 1995 in conformity with generally accepted accounting principles.

As discussed in Note 3 to the financial statements, the Corporation changed its
method of accounting for major maintenance turnarounds and post-employment
benefits effective January 1, 1994.
