TERRA NITROGEN COMPANY, L.P.

FORM 10-K

PART I

ITEMS 1 AND 2. Business and Properties

GENERAL

Terra Nitrogen Company, L.P. ("TNCLP") is a Delaware limited partnership that
conducts its operations through an operating partnership subsidiary, Terra
Nitrogen, Limited Partnership (the "Operating Partnership"). Terra Nitrogen
Corporation ("TNC"), a Delaware corporation, owns a combined 2.0% general
partner interest in, and serves as the general partner (the "General Partner")
of, both TNCLP and the Operating Partnership (collectively the "Partnership",
unless the context otherwise requires). TNC is an indirect, wholly owned
subsidiary of Terra Industries Inc. ("Terra"), a Maryland corporation. Terra,
through its various subsidiaries, is a leading marketer and producer of nitrogen
fertilizer, crop protection products, seed and services for agricultural, turf,
ornamental and other growers. Terra also produces nitrogen products and methanol
for industrial customers.

Ownership of TNCLP is comprised of the general partner interest and the
limited partner interests. The limited partner interests consist of 18,501,576
Common Units. Terra and its subsidiaries owned 12,779,814 Common Units as of
December 31, 1998 and the balance are traded on the New York Stock Exchange
under the symbol "TNH". The Common Units are referred to herein individually as
a "Unit" and collectively as "Units".

PARTNERSHIP PRODUCTS

The Partnership is one of the largest U.S. producers and distributors of
nitrogen fertilizer products, which are used primarily by farmers to improve the
yield and quality of their crops. The Partnership's principal products include
ammonia, urea and urea ammonium nitrate solution ("UAN"). The Partnership's
product sales are heavily weighted toward UAN, and all of its products are sold
on a wholesale basis. Although, to some extent, the various nitrogen fertilizer
products are interchangeable, each has its own distinct characteristics which
result in agronomic preferences among end users. Farmers determine which type of
nitrogen fertilizer to apply depending on the crop, soil and weather conditions,
regional farming practices and relative nitrogen fertilizer prices.

The Partnership's sales mix for each of the years 1998, 1997 and 1996 was
(based on tons sold):



1998 1997 1996
---- ---- ----

Ammonia 15% 15% 13%
Urea 15% 15% 13%
UAN 0% 70% 74%
---- ---- ----
100% 100% 100%


Ammonia. The Partnership produces ammonia, the simplest form of nitrogen
fertilizer and the feedstock for the production of most other nitrogen
fertilizers, at its two plants (the "Plants") located in Verdigris, Oklahoma
(the "Verdigris Plant") and Blytheville, Arkansas (the "Blytheville Plant").
Ammonia is produced by reacting natural gas with steam and air at high
temperatures and pressures in the presence of catalysts.

Ammonia has a nitrogen content of 82% by weight and is generally the least
expensive form of fertilizer per unit of nitrogen. However, because it is a gas
that must be kept under pressure and refrigerated, ammonia is more costly to
store, ship and apply than other nitrogen fertilizer products and must be
applied during a shorter period of the growing season. Ammonia must be injected
into the soil by specialized equipment, and soil conditions limit its
application.

In addition, in certain areas, especially in lesser developed countries,
dealers and farmers lack the equipment necessary to store, ship and apply
ammonia and are required to use other forms of nitrogen fertilizer. Ammonia can
be upgraded into solid or liquid fertilizers, like urea and UAN, which are
easier to transport, store and apply than ammonia.

1


Urea. The Partnership produces urea at the Blytheville Plant, by upgrading a
portion of its ammonia production. Solid urea is produced by converting ammonia
into liquid urea which is then dehydrated, turned into a solid and either
prilled or granulated. Prilled materials are the most common form of solid urea.
The granular form made by the Partnership may command a modest price premium in
certain markets because the consistency in size of the granules (relative to
prills) results in a more controllable spreading pattern and better blending
characteristics.

Urea has a nitrogen content of 46% by weight, the highest level for any solid
nitrogen product. Dry urea is used both as a direct application fertilizer and
as an ingredient in the dry bulk blending of mixed fertilizer grades. Urea is
transported and stored in bulk or in bags and is often blended by distributors
into customized fertilizers containing other nutrients.

UAN. The Partnership produces UAN at the Verdigris Plant and at the
Blytheville Plant by upgrading a portion of its ammonia production. UAN is
produced by combining liquid urea and ammonium nitrate in water. UAN is a liquid
fertilizer and, unlike ammonia, is odorless and does not need to be refrigerated
or pressurized for transportation or storage.

The nitrogen content of UAN is typically 28% to 32%. As a liquid, UAN has many
advantages over solid fertilizers and gaseous ammonia. UAN may be applied more
uniformly than non-liquid products and may be mixed with various crop protection
products or other nutrients, permitting the farmer to apply several materials
simultaneously rather than in separate applications, thus reducing energy and
labor costs. In addition, UAN, unlike ammonia, may be applied from ordinary
tanks and trucks and can be sprayed on, injected into the soil, or applied
through irrigation systems, throughout the growing season. Due to its stable
nature, UAN may be used for no-till row crops where fertilizer is spread on the
surface of the soil but may be subject to volatilization losses. The use of
conservation tilling, which reduces erosion, has increased in the United States
over the past decade, and the Partnership believes this trend, if continued,
should increase UAN demand.

MARKETING AND DISTRIBUTION

The Partnership sells its products primarily in the Central and Southern
Plains and Cornbelt regions of the United States. The Partnership's two Plants
are located on waterways near the major crop producing and consuming areas of
the United States, where the Partnership has ready access to barge, truck and
rail transportation at both Plants and an ammonia pipeline at the Verdigris
Plant to transport product to its primary markets. The Partnership's products
are marketed and distributed through an organization that is based out of Sioux
City, Iowa and provides combined services to the Partnership and Terra. For
further information on the combined organizations of the General Partner and its
affiliates, see "Certain Relationships and Related Transactions".

All of the Partnership's sales are at the wholesale level. The Partnership's
customers for fertilizer products are dealers, national farm retail chains,
distributors and other fertilizer producers and traders. National farm retail
chains have both distribution and application capabilities. Distributors operate
as wholesalers and sell directly to dealers and national farm retail chains,
who, in turn, sell directly to farmers. Many dealers maintain storage capacity
for year-round inventory as well as application equipment. The majority of the
Partnership's sales of nitrogen fertilizer is made to dealers. For the year
ended December 31, 1998, sales to Terra totaled $26.3 million, or 10.5% of the
Partnership's sales. For a description of the Partnership's sales to affiliates
of the General Partner, see "Certain Relationships and Related Transactions". No
other customer accounted for greater than 10% of the Partnership's 1998 sales.

The Partnership occasionally exports UAN through an export marketing
association comprised of four domestic UAN producers.

Transportation. The Partnership transports product primarily via barge and
railcar. Additionally, the Partnership uses trucks to transport smaller
quantities of product, and the Verdigris Plant distributes ammonia through a
common carrier pipeline. In addition, various supply terminals and
transportation equipment are generally available for the use and benefit of the
Partnership and affiliates of the General Partner. The Partnership has access to
significant storage capacity throughout the Midwestern U.S. through these supply
terminals and by its storing product in various retail service centers of Terra.
See "Certain Relationships and Related Transactions."

Capacity Utilization* 104% 105% 105%


* Capacity utilization is determined by dividing the gross tons of
product produced by the tons of capacity at expected operating
rates and onstream factors.

Verdigris Plant. The Verdigris facility is located at the Port of Catoosa, in
Rogers County, Oklahoma. On the Verdigris site are the Verdigris Plant and the
Port Terminal. The Verdigris Plant is owned in fee by the Partnership, while the
Port Terminal is leased from the Tulsa-Rogers County Port Authority. The
leasehold interest is scheduled to expire on April 30, 2004, and the Partnership
has the option to renew the lease for an additional term of five years. The
Verdigris Plant consists of two ammonia plants, two nitric acid plants and two
UAN solution plants. The Verdigris Plant produces primarily ammonia and UAN
solution. In 1998, approximately 71% of its ammonia production was converted
into UAN. In addition, the Verdigris Plant also contains carbon dioxide and
argon recovery facilities. The Verdigris Plant's sale of by-product carbon
dioxide and argon reduces the cost of production of nitrogen products. The
Verdigris Plant transports its products by barge, truck, rail and pipeline. The
Partnership's assets at the Verdigris Plant are subject to an encumbrance in
favor of lenders.

Blytheville Plant. The Blytheville Plant is located in Mississippi County,
Arkansas, adjacent to the Mississippi River. The Blytheville Plant consists of
an ammonia plant, a granular urea plant and a UAN solution plant. In 1998,
approximately 65% of its ammonia was converted into granular urea and UAN. The
ammonia facility at the Blytheville Plant is leased from the City of Blytheville
at a nominal annual rental. The lease term is scheduled to expire on November
30, 2004, and the Partnership has the option to extend the lease for eleven
successive terms of five years each at the same rental rate. The Partnership 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 facility is also leased
from the City of Blytheville. The lease is scheduled to expire on November 1,
2005, and the Partnership has the option to renew the lease for three successive
periods of five years each at a nominal annual rental. The Partnership also has
an option to purchase the property for a nominal price. The Blytheville Plant
has access to a distribution system which includes rail, truck and barge
transportation. This distribution network gives the Blytheville Plant the
flexibility to serve the Eastern U.S. fertilizer markets. The Partnership's
assets at the Blytheville Plant are subject to an encumbrance in favor of
lenders.

Terminal Facilities. The Partnership owns and operates four terminals used in
the storage and distribution of product to customers. The Dublin Terminal, a UAN
terminal owned by the Partnership in fee, is located in Henry and Wayne
Counties, Indiana. The Blair Terminal, an ammonia and UAN terminal facility in
which the Partnership holds a fee interest and a leasehold interest, is located
in Washington County, Nebraska. The Pekin Terminal, a UAN terminal in which the
Partnership holds a leasehold interest, is located in Tazewell County, Illinois.
The Shattuc Terminal, a UAN terminal owned by the Partnership in fee, is located
in Clinton County, Illinois. The leasehold portions of both the Blair Terminal
and the Pekin Terminal properties are leased from Conoco Inc. under a capital
lease. The lease is scheduled to terminate on November 30, 2000. The Partnership
has an option to purchase these properties for a nominal price at the end of the
lease term. In addition, as of December 31, 1998, the Partnership had access to
leased space in 78 terminals located in numerous states.

RAW MATERIALS

Natural gas is the primary raw material used in the production of ammonia and
is also the primary fuel used in the Partnership's ammonia production processes.
The Partnership purchases natural gas from unaffiliated sources. The purchase,
transportation and forward pricing activities of natural gas account for a large
majority of the Partnership's

3


production costs, and represented 54% of total costs and expenses during 1998. A
significant increase in the price of natural gas that is not recovered through
an increase in nitrogen fertilizer prices would have a material adverse effect
on the Partnership's profitability and cash flow. Annual gas usage in the
Partnership's Plants is approximately 56 million MMbtus (million British Thermal
Units). The Partnership has entered into firm transportation contracts to
minimize the risk of interruption or curtailment of natural gas supplies.

The Partnership's natural gas procurement policy is to effectively fix or cap
the unit cost of 40% to 80% of its natural gas requirements for the upcoming 12
months and up to 50% of its natural gas requirements for the subsequent two-year
period using supply contracts, financial derivatives and other forward pricing
techniques in an attempt to gain some protection against natural gas price
increases on the spot market. Consequently, if natural gas prices were to
increase in a future period the Partnership may benefit from these forward
pricing techniques; however, if natural gas prices were to fall, the Partnership
may incur costs above the spot market price as a result of such policies.

The settlement dates for such financial instruments are scheduled to coincide
with gas purchases during such future periods. These instruments reference
physical natural gas prices or appropriate NYMEX futures contract prices. The
contracts' physical prices are frequently based on the Henry Hub Louisiana
price, which is the most common and financially liquid location of reference for
financial derivatives related to natural gas; however, natural gas supplies for
the Partnership's two production facilities are purchased from various suppliers
at locations that are different from Henry Hub. This creates a location basis
differential between the contract price and the physical price of natural gas.
Accordingly, the use of financial derivatives may not exactly offset the change
in price of physical gas. Therefore, the Partnership has entered into basis
swaps to maintain fixed prices for the location basis differential. As of
December 31, 1998, the Partnership had effectively fixed or capped the price of
a portion of its natural gas requirements for 1999 and 2000 in line with its gas
procurement policy mentioned above. Liquidation of these financial derivatives
based on December 31, 1998 market prices would have resulted in a loss of $4.9
million.

Verdigris Plant Supply. The Verdigris Plant obtains natural gas under a
transportation agreement with Oklahoma Natural Gas Company ("ONG") that will
expire in 2004. Under the provisions of the agreements, the Partnership has the
option to: (a) purchase all or part of its natural gas requirements from ONG at
prices periodically offered by ONG, (b) purchase natural gas from third parties
or (c) use any combination of (a) or (b). Except under certain limited
circumstances, all natural gas purchased by the Verdigris Plant must be
transported to the Plant on ONG's pipeline system under interruptible
transportation agreements.

Blytheville Plant Supply. The Partnership has agreements for the
transportation of natural gas to the Blytheville Plant. The primary term of the
agreements expires on May 1, 2001.

SEASONALITY AND VOLATILITY

Nitrogen fertilizer is a global commodity and generally has no proprietary
distinction. The U.S. nitrogen fertilizer business is both seasonal and volatile
due to a number of factors that affect U.S. and world supply and demand.
Approximately 60% of all nitrogen fertilizer consumed in the United States is
applied on acreage used for growing corn and wheat. Because of its dependence on
U.S. agricultural markets, the Partnership's business is seasonal to the extent
that the Partnership typically realizes higher prices and accordingly more
revenues on its products in the second quarter. The seasonality of the
Partnership's business is the result of the U.S. agricultural growing season,
which imposes the need to build inventories for the annual peak periods of
fertilizer application and generally results in higher fertilizer prices during
such peak periods. Prices for fertilizer typically peak in the spring, drop in
the summer, increase in the fall (as depleted inventories are restored) through
the spring. However in 1997 and 1998, as discussed below, nitrogen fertilizer
prices declined during the summer and continued to decline during the fall and
winter as a result of increased production capacity in the industry.

In recent years, additional UAN storage capacity has been built which allows
the Partnership's customers to purchase more product during the fall and winter
months. As a result, there may be a shift in Partnership UAN sales from the
first and second quarters of the year to the third and fourth quarters. While
the third and fourth quarter sales volume may now generally be expected to
represent a higher percentage of the annual sales volume, the second quarter
continues to be the Partnership's strongest quarter producing the highest sales
volume and earnings.

The Partnership's revenues are dependent on U.S. agricultural conditions,
which can be volatile as a result of a number of factors, the most important of
which are weather patterns and conditions (particularly during periods of high

4


fertilizer application), current and projected grain stocks and prices, grain
export prices and supports, and the U.S. government's agricultural policy. U.S.
governmental policies were designed to regulate or influence the number of acres
planted, the level of grain inventories, the mix of crops planted and crop
prices in order to mitigate price and grain inventory volatility. The enactment
of the Federal Agriculture Improvement and Reform ("FAIR") Act during 1996 ended
government acreage reduction and production control measures and allowed farmers
more flexibility in planting. As a result, additional acres were brought into
production during 1996 and this increase in acreage production, if sustained,
could have a positive impact on the fertilizer industry over the next few years.
However, during 1997 and 1998, the impact of the increase in acreage production
was more than offset by increased nitrogen fertilizer production capacity from
new plants and expansion of existing plants by competitors (see "Competition").

Nitrogen fertilizer producers experienced favorable market conditions in 1995
and 1996 which led to increased supply since 1997 through the construction of
new plants and expansion of existing facilities. Future nitrogen fertilizer
prices will depend on, among other things, to what extent increased worldwide
supply will be absorbed by increased demand or to what extent marginal
production capacity is shut down.

COMPETITION

The nitrogen fertilizer industry is highly competitive. Competition takes
place largely on the basis of price, reliability and deliverability. The
relative cost and availability of natural gas, the efficiency of production
facilities and the ability to transport finished goods to end users are
important competitive factors. The Partnership's domestic competitors include
large farm cooperatives, other independent fertilizer companies and subsidiaries
or divisions of larger energy companies. In addition, nitrogen fertilizers
imported into the United States compete with domestically produced nitrogen
fertilizers, including those of the Partnership. Some of the Partnership's
principal competitors may have greater total resources and may be less dependent
on earnings from nitrogen fertilizer sales than is the Partnership. Countries
with inexpensive sources of natural gas, particularly those in the former Soviet
Union and the Middle East, can produce nitrogen fertilizers at a low cost.
However, political instability and transportation costs can serve as deterrents
to exporting nitrogen fertilizers to the U.S. Favorable market conditions in the
mid-1990s have resulted in nitrogen fertilizer production capacity increases,
and additional capacity started up in 1998 with more expected in the next few
years. If increasing demand is insufficient to absorb new supplies generated by
these facilities, profit margins could decline further in future periods.

ENVIRONMENTAL MATTERS

The Partnership is subject to federal, state and local environmental, health
and safety laws and regulations, particularly relating to air and water quality.
In the course of its ordinary operations, the Partnership has and will generate
wastes, which may fall within the definition of "hazardous substances" under
federal or state laws. If such wastes have been disposed of at sites which are
targeted for cleanup by federal or state regulatory authorities, the Partnership
may be among those responsible under the Comprehensive Environmental Response,
Compensation and Liability Act ("CERCLA") or analogous state laws for all or
part of the costs of such cleanup.

The Partnership believes that the procedures currently in effect at all of its
facilities for the production, handling and transportation of all materials are
consistent with industry standards and in compliance with applicable
environmental, health and safety laws in all material respects. In addition, in
connection with the Asset Purchase Agreement dated February 7, 1990, between TNC
and Freeport-McMoRan Resource Partners, Limited Partnership ("FMRP"), as
amended, by which TNC purchased certain nitrogen fertilizer operations from FMRP
(the "1990 TNC Acquisition"), FMRP agreed to provide TNC a limited indemnity
(the "Freeport Indemnity") for certain environmental liabilities that are the
subject of official notice from a court or governmental agency. The Freeport
Indemnity encompasses all costs incurred in respect of all such liabilities
associated with the off-site disposal of hazardous substances or other solid
wastes generated by FMRP prior to the 1990 TNC Acquisition closing date,
February 28, 1990.

Based on its current knowledge, the Partnership does not expect any capital
expenditures relating to environmental matters to have a material adverse effect
on its results of operations, financial condition, capital resources, liquidity
or cash flow. There can be no assurance, however, that additional environmental
matters resulting in material liabilities or expenditures will not be discovered
or that, in the future, material expenditures for such matters will not be
required by changes in law.

5


EMPLOYEES

The Partnership does not have any employees, officers or directors.

The General Partner is responsible for the management of the Partnership. As
of December 31, 1998, the General Partner had 350 employees. None of the General
Partner's employees are subject to collective bargaining agreements. The General
Partner considers its labor relations to be good.

LIMITED CALL RIGHT

If at any time less than 25% of the issued and outstanding units are held by
non-affiliates of the General Partner, the Partnership may call, or assign to
the General Partner or its affiliates its right to acquire, all such outstanding
units held by non-affiliated persons. The General Partner and its affiliates
owned 69% of the Common Units at December 31, 1998. If and when the 75%
ownership threshold is met, TNCLP shall give at least 30 but not more than 60
days notice of its decision to purchase the outstanding units. The purchase
price per unit will be the greater of (1) the average of the previous twenty
trading days closing prices as of the date five days before the purchase is
announced or (2) the highest price paid by the General Partner or any of its
affiliates for any unit within the 90 days preceding the date the purchase is
announced.

ITEM 3. Legal Proceedings

There is no pending or threatened litigation to the knowledge of the
Partnership that would have a material adverse effect on the business or
financial condition of the Partnership.

ITEM 4. Submission of Matters to a Vote of Unitholders

Not Applicable.

PART II

ITEM 5. Market for Registrant's Units and Related Unitholder Matters

Prior to April 1, 1997, the SPUs of TNCLP were listed and traded on the New
York Stock Exchange under the symbol, TNH. After March 31, 1997, the Common
Units traded under the symbol TNH on the New York Stock Exchange. The high and
low sales prices of the Common Units (previously SPUs) for each quarterly period
for 1998 and 1997, as reported on the New York Stock Exchange Composite Tape,
were as follows:



1998 1997
Quarter High Low High Low
------- ---- --- ---- ---

1st $30.6250 $26.8125 $45.3750 $35.5000
2nd 31.0000 22.3125 43.8750 37.8750
3rd 21.0625 18.1250 42.3750 32.2500
4th 18.6875 9.3750 38.1875 23.2500


Based on information received from TNCLP's transfer and servicing agent, the
number of registered unitholders as of February 26, 1999 is 693. TNC owned
11,779,814 Common Units as of December 31, 1998.

The quarterly cash distributions paid to the Units and the General Partner in
1998 and 1997 were as follows:



Amount Per Amount Per Amount Distributed
Senior Preference Common to General Partner
Unit Unit

1998:
First Quarter - $1.17 $ 3,431,000
Second Quarter - - 0
Third Quarter - 1.72 9,895,000
Fourth Quarter - - 0

1997:
First Quarter $.605* $1.50 $10,476,778
Second Quarter .605* 1.02 1,835,535
Third Quarter - 2.38 26,686,249
Fourth Quarter - .29 109,543


* The distributions paid in the first and second quarters of 1997
to the holders of the SPUs represented an amount equal to the MQD for
each quarter. Nonconverting SPU holders were not entitled to
participate in cash distributions in excess of the MQD after December
31, 1996.

Cash distributions are based on Available Cash for the quarter as defined in
TNCLP's limited partnership agreement. Available Cash is defined generally as
all cash receipts less all cash disbursements, adjusted for changes in certain
reserves established as the General Partner determines in its reasonable
discretion to be necessary. There are a number of factors which affect the
amount of taxable income reported to unitholders including Partnership earnings,
capital spending and cash distributions.

ITEM 7. Management's Discussion and Analysis of Financial Condition and Results
of Operations

FACTORS THAT AFFECT OPERATING PERFORMANCE

Factors that may affect the Partnership's future operating results include:
the relative balance of supply and demand for nitrogen fertilizers, the number
of planted acres, the effects general weather patterns have on timing and
duration of field work for crop planting and harvesting, the availability and
cost of natural gas, the effect of environmental legislation on demand for the
Partnership's products, the availability of financing sources to fund seasonal
working capital needs, and the potential for interruption due to accident or
natural disaster.

Although the Partnership's revenues are principally domestic, nitrogen
fertilizer is a global commodity thus the worldwide relative balance of supply
and demand for nitrogen fertilizer can impact Partnership sales. Worldwide
demand is affected by the growing population and improving economies in
developing countries. Worldwide capacity and the availability of nitrogen
product exports from major producing areas affect supply. Due to several years
of favorable economics in the industry, capacity additions in the form of new
and expanded production facilities have been undertaken. The new nitrogen
fertilizer supplies that have come on-stream have adversely impacted profit
margins until increased demand is sufficient to absorb new supplies or marginal
production capacity is shut down.

Demand for nitrogen fertilizer in the United States comes primarily from the
agricultural market. Approximately 60% of all nitrogen fertilizer is applied to
acreage for corn and wheat. The enactment of the FAIR Act in 1996 ended
government acreage reduction and production control measures and allowed farmers
more flexibility in planting. Changes in corn and wheat acreages can have a
significant effect on the demand for the Partnership's products.

Weather can have a significant effect on demand for the Partnership's
products. Weather conditions that delay or intermittently disrupt field work
during the planting season may result in fewer nitrogen applications. 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 reduce the amount of fertilizer
purchased in the future.

The Partnership's margins are also influenced by the cost of natural gas, the
primary raw material in the production of nitrogen fertilizers. In 1998,
natural gas costs accounted for approximately 54% of the Partnership's total
costs and expenses. It is the policy of the Partnership to hedge 40-80% of its
natural gas requirements for a one-year period, and up to 50% of its
requirements for the subsequent two-year period. The Partnership manages the
market price volatility of natural gas prices through the use of derivative
commodity instruments. Changes in the market value of these instruments have a
high correlation to changes in the spot price of natural gas. The fair value of
these instruments is estimated based on quoted market prices from brokers and
computations prepared by the Partnership. Annual procurement requirements for
natural gas are approximately 56 million MMbtu. The Partnership has hedged 59%
of its 1999 requirements and 15% of its 2000 requirements. Market risk is
estimated as the potential loss in fair value resulting from a hypothetical 10%
adverse change in price. As of December 31, 1998, the Partnership's market risk
exposure related to future natural gas requirements being hedged was $7.4
million based on the sensitivity analysis. This hypothetical adverse impact on
natural gas derivative instruments would be more than offset by lower costs for
natural gas purchases.

The Partnership's business is highly seasonal with the majority of sales
occurring during the second quarter in conjunction with spring planting
activity. Due to the seasonality of the business and the relatively brief
periods during which products can be used by customers, the Partnership builds
inventories during the first quarter of the year to ensure timely product
availability during the peak sales season. For its current level of sales, the
Partnership requires lines of credit to fund inventory increases and to support
customer credit terms. The Partnership believes that its credit facilities are
adequate for expected sales levels in 1999.

The Partnership is subject to federal, state, and local environmental, health,
and safety laws and regulations, particularly relating to air and water quality.
In the course of its ordinary operations, the Partnership generates wastes that
may fall within the definition of "hazardous substances" under federal or state
laws. The Partnership's production facilities and storage locations require
ongoing operating expenditures to remain in compliance with environmental
regulations. These operating costs consist largely of items related to
electrical and chemical usage, waste disposal, laboratory analysis and fees for
outside consultants and contractors.

9


The Partnership's operations may be subject to significant interruption if one
or more of its facilities were to experience a major accident or other natural
disaster. The Partnership currently maintains insurance (including business
interruption insurance) and expects that it will continue to do so in an amount
that it believes is sufficient to allow the Partnership to withstand major
damage to any of its facilities.

RISK MANAGEMENT AND FINANCIAL INSTRUMENTS

Market risk represents the risk of loss that may impact the financial
position, results of operations or cash flows of the Partnership due to adverse
changes in financial and commodity market prices and rates. The Partnership uses
derivative financial instruments to manage risk in the area of changes in
natural gas prices.

It is the general policy of the Partnership to avoid unnecessary risk and to
limit, to the extent practical, risks associated with operating activities.
Management of the Partnership may not engage in activities that expose the
Partnership to speculative or non-operating risks. Management is expected to
limit risks to acceptable levels. The use of derivative financial instruments is
consistent with the overall business objectives of the Partnership. Derivatives
are used to manage operating risk within the limits established by the
Partnership's Board of Directors, and in response to identified exposures,
provided they qualify as hedge activities. As such, derivative financial
instruments are used to hedge firm commitments and forecasted commodity purchase
transactions.

RESULTS OF OPERATIONS: 1998 COMPARED WITH 1997

The Partnership's sales volumes and prices for the twelve months ended
December 31, 1998 and 1997 were as follows:



1998 1997
------------------------------------ -------------------------------------
Sales Volume Avg. Unit Price Sales Volume Avg. Unit Price
(000 tons) ($ / ton) (000 tons) ($ / ton)
---------- --------- --------- ---------

Ammonia 456 129 475 183
UAN 2,151 64 2,249 79
Urea 453 115 496 139


Revenues for the year ended December 31, 1998 declined $84.5 million, or 25%,
primarily due to lower sales prices for all products and to a lesser degree,
lower sales volumes. Nitrogen prices fell during 1998 due to lower worldwide
demand for urea, increased nitrogen production capacity and erratic weather
patterns in the Partnership's markets.

Wet weather in some Midwestern areas during the spring and drought conditions
in the Southwest led to lower demand for UAN. As a result of increased UAN
availability and lower alternate nitrogen prices, the Partnership's UAN average
unit sale price declined 19% compared with 1997. In addition, lower grain prices
caused some growers to delay post-harvest fertilizer applications, and
anticipated continued price weakness caused some fertilizer dealers to delay
filling inventories with urea and solutions.

Urea average unit sales price declined 17% in 1998 compared with 1997 due to
the continuation of a significant reduction in China's purchases in the world
markets. China had been a major purchaser of urea for import prior to 1997, but
increased production in that country led to elevated inventories and a ban on
all urea imports until the inventories are reduced. This created excess supply
in the world markets and led to significantly lower prices during 1998.

Cost of goods sold as a percentage of revenues increased to 81% for 1998 from
65% in 1997 due to lower sales prices somewhat offset by lower natural gas
costs. The Partnership's natural gas costs decreased 5% in 1998 compared with
1997. The Partnership's forward pricing activities produced $5.9 million in cost
savings compared with spot market natural gas prices during 1998 compared with
$25.6 million in cost savings in 1997.

Operating expenses decreased $3.0 million, or 25%, due to lower pension,
administrative and overhead expense allocations from TNC and Terra.

Interest expense was essentially unchanged in 1998 compared to 1997.

10


Interest income declined $2.2 million during 1998 due to lower levels of cash
and short-term investments, the result of decreased profitability.

Net income per limited partner unit is computed by dividing net income, less
an approximate 24% and 26% share allocable to the General Partner for the years
ended December 31, 1998 and 1997, respectively, by 18,501,576 limited partner
units. According to the Agreement of Limited Partnership of TNCLP, net income is
allocated to the General Partner and the Limited Partners in each taxable year
in the same proportion that Available Cash for such taxable year was distributed
to the General Partner and the Limited Partners. Distributions of Available Cash
are made 98% to the Limited Partners and 2% to the General Partner, except that
the General Partner is entitled, as an incentive, to larger percentage interests
to the extent that distributions of Available Cash exceed specified target
levels, which were not met. Available Cash for 1998 decreased $103.6 million
from 1997 due primarily to lower net income in 1998.

1997 COMPARED WITH 1996

The Partnership's sales volumes and prices for the twelve months ended
December 31, 1997 and 1996 were as follows:



1997 1996
------------------------------------ -------------------------------------
Sales Volume Avg. Unit Price Sales Volume Avg. Unit Price
(000 tons) ($ / ton) (000 tons) ($ / ton)
---------- --------- ---------- ---------

Ammonia 475 183 394 186
UAN 2,249 79 2,324 92
Urea 496 139 419 179


Revenues for the year ended December 31, 1997 declined $27.8 million, or 8%,
due to lower sales prices for all products and primarily for urea and UAN. Also
contributing to the lower revenues were lower sales volumes for UAN partially
offset by higher ammonia and urea sales volumes. Nitrogen prices fell during
1997 due to lower worldwide demand for urea, increased nitrogen production
capacity and erratic weather patterns in the Partnership's markets.

Urea sales prices declined 22% in 1997 compared with 1996 due to a significant
reduction in China's purchases in the world markets. China has been a major
purchaser of urea, but increased production in that country led to elevated
inventories and a ban on all urea imports until the inventories are reduced.
This created excess supply in the world markets and led to significantly lower
prices during 1997.

Wet weather in the South and Southwest led to lower demand for UAN. As a
result of increased UAN availability and lower alternate nitrogen prices, the
Partnership's UAN prices declined 14% compared with 1996. In addition, spring
weather conditions in the Midwest favored ammonia application over UAN
application. Contributing to favorable ammonia market conditions during 1997
were increased corn acres and greater demand for ammonia in the manufacture of
upgraded nitrogen fertilizer and industrial products.

Cost of goods sold as a percentage of revenues increased to 65% for 1997 from
49% in 1996 due to lower sales prices and higher natural gas costs. The
Partnership's natural gas costs increased 29% in 1997 compared with 1996. The
Partnership's forward pricing activities produced $25.6 million in cost savings
compared with spot market natural gas prices during 1997 compared with $37.1
million in 1996.

Operating expenses in 1997 decreased $.9 million, or 7%, due primarily to $3.4
million lower administrative and overhead expense allocations offset by $2.8
million higher freight and transportation allocations from TNC and Terra.

Interest expense increased $1 million in 1997 due to the discount on accounts
receivable sold under the accounts receivable securitization facility and to the
borrowing under the revolving credit agreement used to fund the redemption of
the Senior Preference Units.

Interest income declined $2.6 million during 1997 due to lower levels of cash
and short-term investments and the elimination of the Reserve Amount.

11


Net income per limited partner unit is computed by dividing net income, less
an approximate 26% and 33% share allocable to the General Partner for the years
ended December 31, 1997and 1996 respectively, by 18,501,576 limited partner
units for the year ended December 31, 1997 and by 18,808,778 limited partner
units for the year ended December 31, 1996.

The net income allocated to the General Partner decreased to 26% for the year
ended December 31, 1997 due to the decrease in Available Cash distributed to the
General Partner. According to the Agreement of Limited Partnership of TNCLP, net
income is allocated to the General Partner and the Limited Partners in each
taxable year in the same proportion that Available Cash for such taxable year
was distributed to the General Partner and the Limited Partners. Distributions
of Available Cash are made 98% to the Limited Partners and 2% to the General
Partner, except that the General Partner is entitled, as an incentive, to larger
percentage interests to the extent that distributions of Available Cash exceed
specified target levels, which were not met. Available Cash for 1997 decreased
$82.3 million from 1996 due primarily to lower net income in 1997 partially
offset by the elimination of the $18.5 million Reserve Amount and to an increase
in 1996 Available Cash as a result of the impact of TNCLP's participation in an
accounts receivable securitization facility.

CAPITAL RESOURCES AND LIQUIDITY

Net cash provided by operating activities for 1998 was $45.2 million, a
decrease of $65.8 million from 1997, principally due to lower net income.
Working capital decreased $19.4 million primarily due to an increase of $19.8
million in inventories, the result of substantially lower than anticipated
sales, and an increase of $2.7 million in accounts receivable offset by an
increase of $15.0 million in the amounts due to affiliates and a decrease of
$30.2 million in cash.

The Partnership's principal needs for funds are to support its working capital
requirements, distributions to partners, if any, and capital expenditures. The
Partnership intends to fund such needs from net cash provided by operating
activities, and, to the extent permitted thereunder, from funds available under
the Operating Partnership's revolving credit facility. At December 31,1998, the
Operating Partnership had $18 million of unused borrowing capacity under its
revolving credit facility. The Partnership believes that such sources of funds
will be adequate to meet the Partnership's working capital needs, make quarterly
distributions to partners, if any, and fund the Partnership's capital
expenditures during 1999.

Quarterly distributions to the partners of TNCLP are based on Available Cash
for the quarter as defined in the TNCLP Agreement of Limited Partnership.
Available Cash is defined generally as all cash receipts less all cash
disbursements, adjusted for changes in certain reserves established as the
General Partner determines in its reasonable discretion to be necessary.
Distributions paid to all partners were $66.8 million in 1998 and $135.5 million
in 1997.

Distributions on the Common Units are cumulative to the extent that, for any
calendar quarter, if a distribution of at least $0.605 is not paid to the
holders of the Common Units, the amount of the shortfall (plus any arrearages
from prior quarters) will be paid out of Available Cash in subsequent quarters
before any incentive distributions are paid to the General Partner. As of
December 31, 1998, the accumulated distribution arrearage for the Common Units
was $11.2 million ($.605 per unit). The Partnership's accumulated arrearage will
likely increase by $11.2 million ($.605 per unit) as no distributions were
declared in early 1999.

RECENTLY ISSUED ACCOUNTING STANDARDS

In June 1998, the Financial Accounting Standards Board (FASB) issued Statement
of Financial Accounting Standards (SFAS) 133, "Accounting for Derivative
Instruments and Hedging Activities" which will be effective for fiscal years
beginning after June 15, 1999. The Partnership will adopt SFAS 133 effective
January 1, 2000. At this time, the Partnership has not determined the impact of
SFAS 133 on its results of operations, financial position, or cash flows.

YEAR 2000 ISSUE

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

The Partnership relies upon Terra to provide Management Information Systems
services.

12


Terra has assigned dedicated resources to address its year 2000 issues with a
Year 2000 Steering Committee providing management oversight and coordination.
The Partnership has also published Year 2000 Information and Disclosures on
Terra's website (http://www.terraindustries.com). In general, management
-------------------------------
believes the "State of Readiness" for the Partnership is such that it will be
ready for Year 2000 issues on time.

Terra's management information systems (MIS) environment has been assessed for
Year 2000 issues and some remedial actions have been identified. The cost of
remedial actions for the MIS area is not material to the Partnership. Nearly all
of these remedial actions are complete with minimal cost. Testing is
substantially complete with minimal cost. Testing is substantially complete with
the mainframe hardware systems and the associated software, with the exception
of a few software packages originally purchased from third parties that are
scheduled to be updated in 1999.

Terra recently completed an organization-wide review of all possible computing
functions, including the process control systems and instrumentation in the
manufacturing facilities. Some remedial actions have been identified in a few
areas and the cost of these remedial actions is not expected to be material to
the Partnership.

Terra is also assessing Year 2000 issues in relation to its customers,
suppliers and other constituents because the action or inaction of third parties
may materially affect the Partnership. An initial assessment of key third
parties, including utility suppliers, has been completed and some follow up is
ongoing.

Although Terra expects that there will be no significant adverse consequences
relating to its Year 2000 issues, the Partnership believes its most reasonably
likely worst case Year 2000 scenario involves the interruption of its
manufacturing facilities due to failed utility supplies or some other cause. The
Partnership has in place contingency plans to deal with such interruptions,
although restarting these facilities may be dependent on the resumption of
utilities from sole source suppliers. Other general contingency planning efforts
continue to be evaluated and refined for precautionary purposes.

Terra anticipates that it will complete all assessment, remediation, testing,
and contingency planning efforts for Year 2000 issues in the third quarter of
1999. Based on substantial completion of activities to date, the Partnership
anticipates that Year 2000 issues, including the historical and estimated costs
of remediation, will not have a material effect on its business, results of
operations or financial condition. However, the costs or consequences of
incomplete or untimely resolution of Year 2000 issues by the Partnership or
third parties could have a material adverse affect on the Partnership.

FORWARD LOOKING PRECAUTIONS

Information contained in this report, other than historical information, may
be considered forward looking. Forward looking information reflects Management's
current views of future events and financial performance that involve a number
of risks and uncertainties. The factors that could cause actual results to
differ materially include, but are not limited to, the following: general
economic conditions within the agricultural industry, competitive factors and
pricing pressures (principally, sales prices of nitrogen products and natural
gas costs), changes in product mix, changes in the seasonality of demand
patterns, changes in weather conditions, changes in agricultural regulations,
and other risks detailed in the "Factors that Affect Operating Results" section
of this discussion.

"Compensation" under the Retirement Plan includes all salaries and wages paid
to a participant, including bonuses, overtime, commissions and amounts the
participant elects to defer under Terra's Employees' Savings and Investment
Plan. Covered earnings are limited by Section 401(a)(17) of the Internal Revenue
Code ("Code") to $160,000 in 1998. The above benefits are subject to the
limitations of Section 415 of the Code, which provided for a maximum annual
payment of approximately $130,000 in 1998. Under the Excess Benefit Plan,
however, Terra will supplement those benefits so that the amount the participant
will receive will be equal to the amount that would have been received under the
Retirement Plan but for such limitations. "Compensation" under the Excess
Benefit Plan also includes amounts deferred under the Supplemental Deferred
Compensation Plan. Eligible compensation for Burton M. Joyce as of the end of
the last calendar year is $1,061,347 and the estimated years of service for Mr.
Joyce is 12.

Certain executive officers of TNC and certain other employees are entitled to
the estimated annual retirement benefit under the Retirement Plan and Excess
Benefit Plan as set forth in the following table:

EMPLOYEE CONTRACTS AND TERMINATION OF EMPLOYMENT AND CHANGE IN CONTROL
ARRANGEMENTS

The named executive officers (other than Mr. Hlobik) are parties to Executive
Retention Agreements with Terra. These agreements provide for benefits in the
event such officer's employment is terminated at any time within two years
(three years in the case of Mr. Joyce) following a change of control of Terra
(as defined in the agreements) without cause, or by such officer for good
reason. The change of control benefits include: (a) continuation of base salary
and bonus for two years (three years in the case of Mr. Joyce); (b) continuation
of medical and dental benefits for two years (three years in the case of Mr.
Joyce); (c) payment of accrued but unpaid compensation; (d) automatic vesting in
Terra's Excess Benefit Plan with an addition of two years (a maximum of eight
years in the case of Mr. Joyce), to the credited service level and the age of
the participant for purposes of computing the accrued benefits under the Excess
Benefit Plan; (e) certain outplacement services; and (f) office space and
secretarial support for one year for Mr. Joyce. Such benefits are in lieu of any
other severance benefits that may otherwise be payable. Compensation earned from
other employment shall not reduce the amounts otherwise payable by Terra. Terra
also agreed to reimburse each such officer on an after-tax basis for any excise
tax incurred as a result of the "excess parachute payment" provisions of the
Internal Revenue Code.

ITEM 13. Certain Relationships and Related Transactions

The General Partner does not receive a management fee or similar
compensation in connection with its management of the Partnership. Pursuant to
TNCLP's limited partnership agreement and the Operating Partnership's limited
partnership agreement, the General Partner receives:

(i) distributions in respect of its 2% General Partner interest on a
combined basis in TNCLP and the Operating Partnership (See "Market
for Registrant's Units and Related Unitholders Matters");

(ii) distributions in respect of its ownership of limited partner
interests of TNCLP;

(iii) incentive distributions payable to the General Partner out of TNCLP's
Available Cash (as defined) in the event quarterly distributions
exceed specified target levels; and

21


(iv) reimbursement for all direct and indirect costs and expenses incurred
on behalf of the Partnership, all general and administrative expenses
incurred by the General Partner or its affiliates for or on behalf of
the Partnership and all other expenses necessary or appropriate to
the conduct of the business of, and reasonably allocable to, the
Partnership.

Such reimbursement includes the costs of compensation and employee benefit
plans properly allocable to the Partnership. Because certain of the plans are
incentive based, the maximum amount to be reimbursed by the Partnership under
such plans cannot be determined in advance. For the years ended December 31,
1998, 1997 and 1996, the General Partner was entitled to reimbursement in the
amount of $40.0 million, $24.7 million and $25.9 million, respectively, for the
direct and indirect costs and expenses related to the business activities of the
Partnership.

TNC and Terra are parties to an agreement whereby TNC provides certain
general and administrative services for certain Terra affiliates. Certain costs
and expenses incurred by TNC for providing such services are charged (based on
cost) to such affiliates, including the Partnership. Such expenses charged to
the Partnership were $5.4 million, $7.2 million and $7.9 million for 1998, 1997
and 1996, respectively.

Under another agreement between TNC and Terra, certain management and other
services, including, advertising, accounting, legal, human resources, insurance
and risk management, safety and environmental, and corporate relations are
provided by Terra or certain of its affiliates (other than TNC) and charged to
Terra affiliates, including the Partnership, as appropriate. Expenses under this
agreement charged to the Partnership were $3.7 million, $5.0 million and $5.1
million for 1998, 1997 and 1996, respectively.

Certain supply terminals and transportation equipment are generally
available for use by the Partnership and other Terra affiliates. The costs
associated with the operation of such terminals and transportation equipment and
related freight costs incurred to ship product to the various sales points in
the distribution system are centralized. The Partnership and other Terra
affiliates are charged based on usage of such assets and freight costs incurred.
Amounts charged to the Partnership for 1998, 1997 and 1996 were $26.1 million,
$23.3 million, and $20.5 million, respectively.

The Partnership sells product to affiliates of the General Partner at
market prices and terms. During 1998, 1997 and 1996 the Partnership sold $26.3
million, $41.0 million and $41.4 million, respectively, of nitrogen fertilizer
products to affiliates of the General Partner at market prices and terms.
Accounts receivable from Terra were $9.0 million and $314,000 at December 31,
1998 and 1997, respectively.

The Partnership has demand deposit and demand note arrangements with a
Terra subsidiary to allow for excess Partnership cash to be deposited with or
funds to be borrowed from such affiliate. The balance is due on demand and bears
interest based on the Cost Rate under the Accounts Receivable Sale Agreement or
the Eurodollar rate under the Credit Agreement, whichever is higher (7.3% and
6.5% at December 31, 1998 and 1997, respectively). Interest income recorded by
the Partnership on the demand deposit was $1.6 million and $3.5 million for 1998
and 1997, respectively.

INDEPENDENT AUDITORS' REPORT


TO THE PARTNERS
TERRA NITROGEN COMPANY, L.P.

We have audited the accompanying consolidated balance sheets of Terra Nitrogen
Company, L.P. (a limited partnership) as of December 31, 1998 and 1997 and the
related consolidated statements of income, partners' capital, and cash flows for
each of the three years in the period ended December 31, 1998. These financial
statements are the responsibility of the Partnership'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 financial statements present fairly, in all material
respects, the financial position of Terra Nitrogen Company, L.P. at December 31,
1998 and 1997 and the results of their operations and their cash flows for each
of the three years in the period ended December 31, 1998, in conformity with
generally accepted accounting principles.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. ORGANIZATION

Terra Nitrogen Company, L.P. ("TNCLP" or the "Partnership") is a Delaware
limited partnership that owns a 99% limited partner interest as the sole limited
partner in Terra Nitrogen, Limited Partnership (the "Operating Partnership").
Terra Nitrogen Corporation ("TNC"), the General Partner, exercises full control
over all business affairs of the Partnership. TNC owns a 2% combined general
partner interest in both the Partnership and Operating Partnership. TNC has
agreed not to voluntarily withdraw as the General Partner of the Partnership,
subject to certain limited exceptions, prior to January 1, 2002.

TNC is an indirect wholly owned subsidiary of Terra Industries Inc. ("Terra"), a
Maryland corporation, a leading producer and marketer of nitrogen fertilizer,
crop protection products, seed and services for growers and dealers. Terra also
produces nitrogen products and methanol for industrial customers.

Ownership of TNCLP is comprised of the general partner interest and the limited
partner interests. The limited partner interests consist of 18,501,576 Common
Units. Terra and its subsidiaries owned 12,779,814 Common Units as of December
31, 1998 and the balance are traded on the New York Stock Exchange under the
symbol "TNH".

The Partnership primarily evaluates performance and determines the allocation of
resources on an entity-wide basis.

2. SIGNIFICANT ACCOUNTING POLICIES

GENERAL - The Partnership manufactures and sells fertilizer products, including
ammonia, urea and urea ammonium nitrate solution ("UAN"), which are principally
used by farmers to improve the yield and quality of their crops. The
Partnership sells products primarily throughout the United States on a wholesale
basis. The Partnership's customers vary in size and are primarily related to
the agriculture industry and to a lesser extent to the chemical industry.
Credit is extended based on an evaluation of the customer's financial condition,
and generally collateral is not required.

BASIS OF PRESENTATION - The consolidated financial statements reflect the
combined assets, liabilities and operations of the Partnership and the Operating
Partnership. All significant intercompany accounts and transactions have been
eliminated. Income is allocated to the General Partner and the Limited Partners
in accordance with the provisions of the TNCLP Agreement of Limited Partnership
that provides for allocations of income between the Limited Partners and the
General Partner in the same proportion as cash distributions declared during the
year.

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

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 revenue and expenses during the reporting
period. Actual results could differ from these estimates.

CASH AND CASH EQUIVALENTS - TNCLP considers liquid debt instruments with an
original maturity of three months or less to be cash equivalents. The
Partnership has a demand deposit with an affiliate that represents excess
Partnership cash deposited with Terra Capital, Inc. The deposit is due on
demand and bears interest based on the Cost Rate under the Accounts Receivable
Sale Agreement or the Eurodollar rate under the credit agreement, whichever is
higher (7.3%, 6.5% and 6.3% at December 31, 1998, 1997 and 1996, respectively).
Interest income recorded by TNCLP on this deposit was $1.5 million, $3.5 million
and $5.1 million for 1998, 1997 and 1996, respectively.

INVENTORY - Inventories are stated at the lower of average 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 3 to 20 years. Maintenance, other than plant turnaround and catalyst
replacement, and repair costs are expensed as incurred.

F-7


HEDGING TRANSACTIONS - Realized gains and losses from hedging activities and
premiums paid for option contracts are deferred and recognized in the month to
which the hedged transactions relate (see Note 9 Derivative Financial
Instruments)

PLANT TURNAROUND AND CATALYST REPLACEMENT 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,
generally over one or two years, until the next scheduled turnaround. Included
in other non-current assets at December 31, 1998 and 1997 is $8.8 million and
$11.8 million, respectively, of unamortized plant turnaround and catalyst
replacement costs.

INCOME TAXES - The Partnership is not subject to income taxes and the income tax
liability of the individual partners is not reflected in the consolidated
financial statements of the Partnership. The reported amount of assets and
liabilities of the Partnership exceeded the tax basis of the assets and
liabilities by approximately $143 million and $150 million at December 31, 1998
and 1997, respectively.

PER-UNIT RESULTS AND ALLOCATIONS - Net income per limited partner unit is
computed by dividing net income, less an approximate 24%, 26% and 33% share
allocable to the General Partner for the years ended December 31, 1998, 1997and
1996 respectively, by 18,501,576 limited partner units for the year ended
December 31, 1998 and 1997 and by 18,808,778 limited partner units for the year
ended December 31, 1996.

According to the Agreement of Limited Partnership of TNCLP, net income is
allocated to the General Partner and the Limited Partners in each taxable year
in the same proportion that Available Cash for such taxable year was distributed
to the General Partner and the Limited Partners.

NEW ACCOUNTING STANDARDS - In June 1998, the Financial Accounting Standards
Board (FASB) issued Statement of Financial Accounting Standards (SFAS) 133,
"Accounting for Derivative Instruments and Hedging Activities" which will be
effective for fiscal years beginning after June 15, 1999. The Partnership will
adopt SFAS 133 effective January 1, 2000. At this time, the Partnership has not
determined the impact of SFAS 133 on its results of operations, financial
position, or cash flows.

3. AGREEMENT OF LIMITED PARTNERSHIP

The Partnership makes quarterly cash distributions to Unitholders and the
General Partner in an amount equal to 100% of Available Cash, as defined. 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 period December 4, 1991 through December 31, 1996 (the "Preference
Period"), distributions of Available Cash were subject to the rights of Senior
Preference Units (SPUs) to receive $.605 per unit per quarter, plus any
arrearages for minimum payments for prior quarters before any distributions to
Common Unitholders. During the Preference Period, SPUs and Common Units
participated equally in distributions after each class of Units received the
Minimum Quarterly Distribution ("MQD"), subject to the General Partner's right
to receive cash distributions.

F-8


The quarterly cash distributions paid to the Units and the General Partner in
1998, 1997, and 1996 were as follows:

Fourth Quarter 24,136 1.77 9,155 1.77 15,658 -


* The distributions paid in 1997 to the holders of the SPUs represented an
amount equal to the MQD for each quarter. Non-converting SPU holders were not
entitled to participate in cash distributions in excess of the MQD after
December 31, 1996.

Pursuant to the provisions of the TNCLP Agreement of Limited Partnership, the
Preference Period for TNCLP ended on December 31, 1996. For a 90-day period that
commenced on December 31, 1996, the holders of all SPUs had the right to elect
to convert their SPUs into Common Units on a one-for-one basis, effective
December 31, 1996, by delivering to the General Partner a conversion notice. Any
SPUs for which a conversion notice was not received during the 90-day period
remained SPUs. Those units that remained SPUs were entitled to the MQD until
redeemed but did not participate with the Common Units in additional
distributions after December 31, 1996.

Holders of 13,329,162 SPUs converted their units to Common Units and 307,202
units remained SPUs. The Common Units began trading on the New York Stock
Exchange on April 1, 1997 under the symbol TNH.

Pursuant to the provisions of the Agreement of Limited Partnership, on May 27,
1997, the Partnership redeemed all SPUs that did not convert to Common Units at
a redemption price of $21.50 per unit. The SPUs received the MQD of $.605 per
unit for the quarter ended March 31, 1997 in addition to the redemption price.
As a result of the redemption the Reserve Amount totaling $18.5 million was no
longer required and was distributed from Available Cash to holders of the Common
Units and to the General Partner.

If at any time less than 25% of the issued and outstanding units are held by
non-affiliates of the General Partner, the Partnership may call, or assign to
the General Partner or its affiliates its right to acquire, all such outstanding
units held by non-affiliated persons. The General Partner and its affiliates
owned 69% of the Common Units at December 31, 1998. If and when the 75%
ownership threshold is met, TNCLP shall give at least 30 but not more than 60
days notice of its decision to purchase the outstanding units. The purchase
price per unit will be the greater of (1) the average of the previous twenty
trading days' closing prices as of the date five days before the purchase is
announced or (2) the highest price paid by the General Partner or any of its
affiliates for any Unit within the 90 days preceding the date the purchase is
announced.

Distributions on the Common Units are cumulative to the extent that, for any
calendar quarter, if a distribution of at least $0.605 is not paid to the
holders of the Common Units, the amount of the shortfall (plus any arrearages
from prior quarters) will be paid out of Available Cash in subsequent quarters
before any incentive distributions are paid to the General Partner. As of
December 31, 1998, the accumulated distribution arrearage for the Common Units
was $11.2

F-9


million ($.605 per unit). The Partnership's accumulated arrearage will
likely increase by $11.2 million ($.605 per unit) as no distributions were
declared in early 1999.

4. RELATED PARTY TRANSACTIONS

The Partnership has no employees. Pursuant to the provisions of the TNCLP
Agreement of Limited Partnership, TNC, as General Partner, is reimbursed for all
direct and indirect expenses or payments it makes on behalf of the Partnership
and for that portion of TNC's or its affiliates' administrative and overhead
expenses and all other expenses necessary or appropriate to the conduct of the
Partnership's business and reasonably allocable to the Partnership. Costs and
expenses incurred by TNC for providing such services are charged to the
Partnership. For the years ended December 31, 1998, 1997 and 1996, expenses
charged to the Partnership by TNC amounted to $40.0 million, $24.7 million and
$25.9 million, respectively, including $17.9 million, $21.5 million and $21.1
million, respectively, for payroll and payroll-related expenses including
pension costs.

Effective January 1, 1995, under a general and administrative service agreement
between TNC and Terra, certain services including accounting, legal, risk
management, investor relations and certain employee benefit and other employee-
related expenses are provided by Terra to TNC. The portion of these expenses
allocated to TNC that relate to TNC's activities as General Partner are charged
to the Partnership. Expenses under this agreement charged to the Partnership
were $3.7 million, $5.0 million and $5.1 million for the years ended December
31, 1998, 1997 and 1996, respectively.

Certain supply terminals and transportation equipment are generally available
for use by the Partnership and other Terra affiliates. The costs associated with
the operation of such terminals and transportation equipment and related freight
costs incurred to ship product to the various sales points in the distribution
system are centralized. The Partnership or Terra is charged based on usage of
such assets and freight costs incurred. Amounts charged to the Partnership for
the years ended December 31, 1998, 1997 and 1996 were $26.1 million, $23.3
million and $20.5 million, respectively.

TNC's employees are members of the Terra Industries Inc. Employees' Retirement
Plan (the Terra Retirement Plan), a noncontributory defined benefit pension
plan. The accumulated benefits and plan assets of the Terra Retirement Plan are
not determined separately for TNC employees. TNC recorded pension costs of $.8
million, $1.2 million and $1.2 million ($.6 million, $1.0 million and $1.1
million of which was charged to the Partnership) in 1998, 1997 and 1996,
respectively, as its allocated share of the total periodic pension cost for the
Terra Retirement Plan. Benefits are based on years of service and average final
compensation. Pension costs are funded to satisfy minimum requirements
prescribed by the Employee Retirement Income Security Act of 1974.

Terra maintains a qualified savings plan that allows employees who meet
specified service requirements to contribute a percentage of their total
compensation, up to a maximum defined by the plan. Each employee's
contribution, up to a specified maximum, may be matched by TNC based on a
specified percentage of employee contributions. Employee contributions vest
immediately, while Terra's contributions vest over five years. Expenses
associated with TNC's contribution to the Terra qualified savings plan charged
to the Partnership for the years ended December 31, 1998, 1997 and 1996 were
$627,000, $706,000 and $759,000, respectively.

TNC has an incentive compensation plan covering certain key employees which is
based on Terra Nitrogen Division (which consists of the Partnership and the
Nitrogen Manufacturing business represented by Terra's plants located in
Woodward, Oklahoma; Port Neal, Iowa; and Courtright, Ontario) annual earnings
before interest, taxes and minority interest. Expenses for the incentive
compensation plan charged to the Partnership for the years ended December 31,
1998, 1997 and 1996 were $0, $1.5 million and $1.3 million, respectively.

The Partnership sold $26.3 million, $41.0 million and $41.4 million of nitrogen
fertilizer products to Terra at market prices and terms during the years ended
December 31, 1998, 1997 and 1996, respectively. Accounts receivable from Terra
were $9.0 million and $314,000 at December 31, 1998 and 1997, respectively.

Under certain circumstances an affiliate of the Partnership may advance funds to
the Partnership under a demand note.

5. ACCOUNTS RECEIVABLE SECURITIZATION

On August 20, 1996, TNCLP and certain affiliates of the General Partner, through
Terra Funding Corporation ("TFC"), an affiliate of the General Partner and a
limited purpose corporation, entered into an agreement with a financial
institution to sell an undivided interest in their accounts receivable. Under
the agreement, which expires on August 20, 1999, undivided interests in new
receivables may be sold as amounts are collected on previously sold amounts. The
discount on TNCLP's portion of accounts receivable sold in 1998, 1997 and 1996
was $1.5 million, $1.6 million and $.7 million, respectively, and is included in
interest expense in the Consolidated Statements of Income. TNCLP's receivables
sold to TFC under this agreement are sold without recourse, however, the amount
of discount charged on accounts receivable sold is subject to adjustment, on a
prospective basis, based on collection experience.

Terra and its subsidiaries maintain a credit agreement (the "Credit Agreement")
with certain lenders and with Citibank, N.A., as agent. The Operating
Partnership has a $25 million revolving credit facility under the Credit
Agreement. The revolving credit facility expires December 31, 2000. At December
31, 1998, the Operating Partnership had $18.0 million of unused borrowing
capacity under its revolving credit facility. The Partnership has classified
the revolver borrowing as long-term debt since the Partnership has the ability
under its Credit Agreement, and the intent, to maintain this obligation for
longer than one year. Interest on the revolving credit facility is based on the
prime commercial lending rate plus 1.0% or the Eurodollar rate plus 2.0% at the
General Partner's option. At December 31, 1998, the interest rate on the
revolving credit facility was 7.3125%. The Operating Partnership incurs certain
fees in connection with the borrowings discussed above, including a commitment
fee equal to .50% of the unused amount of the revolving credit facility.

Loans under the Credit Agreement are guaranteed by Terra and certain
subsidiaries, including the General Partner, and are secured by pledges of the
stock of significant Terra subsidiaries, including the General Partner, and by
substantially all of the Operating Partnership's assets. The security interest
granted in the Operating Partnership's assets secures only its $25 million
revolving credit facility.

The Credit Agreement contains customary events of default, including those
relating to failure to pay amounts due, misrepresentation, failure to perform
covenants, bankruptcy or insolvency, litigation and unsatisfied judgments,

F-11


violations of the Employee Retirement Income Security Act of 1974, as amended,
and environmental laws and changes in control or ownership.

The Credit Agreement contains covenants customary for financing of this type
including limitations on capital expenditures, additional debt, liens,
receivables sales, investments, changes in lines of business, transactions with
affiliates and limitations on acquisitions. The Credit Agreement also includes
covenants requiring Terra to meet certain financial tests. The Partnership is
not required to meet such financial tests under the Credit Agreement.

Interest paid on long-term debt by the Partnership was $578,000, $605,000 and
$471,000 for the years ended December 31, 1998, 1997 and 1996, respectively.

8. COMMITMENTS AND CONTINGENCIES

The Operating Partnership is committed to various non-cancelable capital and
operating leases for land, buildings and equipment. Total minimum rental
payments are as follows:

Included above is the lease of the Port Terminal at the Verdigris facility. The
leasehold interest is scheduled to expire on April 30, 2004, and the Partnership
has the option to renew the lease for an additional term of five years.

The above amounts include the leases for the ammonia and urea facilities at the
Blytheville Plant. The lease term for the ammonia facility is scheduled to
expire on November 30, 2004 and the Partnership has the option to extend the
lease for eleven successive terms of five years each at the same rental rate.
The urea facility lease is scheduled to expire November 1, 2005, and the
Partnership has the option to renew the lease for three successive periods of
five years each at a nominal annual rental.

Rent expense under non-cancelable operating leases amounted to approximately
$9.0 million, $9.1 million and $6.5 million, including contingent rentals of
$1.6 million, $1.9 million and $1.8 million, based primarily on terminal
throughput, for the years ended December 31, 1998, 1997 and 1996, respectively.

The Partnership has certain commitments with respect to the transportation of
minimum quantities of ammonia, urea and UAN. The transportation of such minimum
quantities is expected to be attained in the normal course of the Partnership's
business. The aggregate amount of required payments under these commitments are:
1999 - $8.2 million; 2000 - $8.4 million; 2001 - $2.5 million; 2002 - $2.5
million; 2003 - $2.5 million: 2004 and after - $3.7 million.

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

F-12


9. DERIVATIVE FINANCIAL INSTRUMENTS

Since 1997, the Partnership has recorded hedging gains and losses related to
natural gas supply requirements based on a pooled resources concept with Terra.
Under the pooled resources concept, hedging gains and losses are allocated to
each manufacturing plant based on gas usage for such plant. Prior to 1997,
hedging gains and losses were specifically identified with a particular plant
based on contractual arrangements for that plant. The change in the allocation
of hedging gains and losses did not have a material impact on the Partnership's
consolidated financial position or results of operations for the years ended
December 31, 1998 and 1997.

The Partnership is subject to risks undertaken by Terra in its policy of using
derivative financial instruments to manage the risk associated with changes in
natural gas supply prices. Derivative financial instruments have credit risk and
market risk. To manage credit risk, Terra enters into derivative transactions
only with counter-parties who are currently rated BBB or better as recognized by
a national rating agency. Terra will not enter into transactions with counter-
parties if the additional transaction will result in credit exposure exceeding
$20 million. The credit rating of counter-parties may be modified through
guarantees, letters of credit or other credit enhancement vehicles.

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

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

1. The item to be hedged must expose the enterprise to price risk.
2. It must be probable that the results of the hedge position substantially
offset the effects of price changes on the hedged item (e.g., there is a
high correlation between the hedge position and changes in market value of
the hedged item).
3. The derivative financial instrument must be designated as a hedge of the
item at the inception of the hedge.

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

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

Natural gas supplies to meet production requirements at the Operating
Partnership's production facilities are purchased at market prices. Natural gas
market prices, as with other commodities, are volatile and futures contracts,
swap agreements and purchased options are used to effectively maintain fixed
prices for a portion of the Operating Partnership's natural gas production
requirements and inventory. The settlement dates for such financial instruments
are scheduled to coincide with gas purchases during such future periods. These
contracts reference physical natural gas prices or appropriate NYMEX futures
contract prices. The contracts physical prices are frequently based on the Henry
Hub, Louisiana price. Natural gas supplies for the Partnership's two production
facilities are purchased from various suppliers at locations that are different
from the Henry Hub. This creates a location basis differential between the
contract price and the physical price of natural gas. Accordingly, the use of
financial derivatives may not exactly offset the change in the price of physical
gas. Therefore, Terra has also entered into basis swaps to maintain fixed prices
for the location basis differential. There are no initial cash requirements
related to the basis swap agreements. Gains and losses on settlement of these
contracts are credited or charged to cost of sales in the month in which the
hedged transaction occurs. Cash flows related to natural gas basis swaps are
reported as cash flows from operating activities. As of December 31, 1998 and
1997, MMbtu's under such contracts totaled 9.0 million and 39.8 million,
respectively. The unrealized gain on basis swaps at December 31, 1998 and 1997
was $700,000 and $30,000 respectively.

Swap agreements are used to hedge natural gas prices, which are agreements with
third parties to exchange cash based on a designated price, which price is
referenced to natural gas market prices or appropriate NYMEX futures contract

F-13


prices. Option contracts are also used and represent agreements giving the
holder of the contract the right to either own or sell a futures or swap
contract at a designated price. Option contracts require initial premium
payments ranging from 2% to 5% of contract value and the futures contracts
require maintenance of cash balances generally 10% to 20% of the contract value.

The following summarizes open natural gas contracts allocated to the Partnership
at December 31, 1998 and 1997:

43,575 $(4,932) 54,908 $12,060
====== ======= ====== =======


The Partnership's annual production requirements are approximately 56 million
MMbtu's of natural gas. Contracts were in place at December 31, 1998 to cover
59% of 1999 natural gas requirements and 15% for 2000. Gains and losses on
settlement of these contracts and premium payments on option contracts are
credited or charged to cost of sales in the month in which the hedged
transaction occurs. The risk and reward of outstanding natural gas positions are
directly related to increases or decreases in natural gas prices in relation to
the underlying NYMEX natural gas contract prices. Realized losses of $1.6
million on closed contracts relating to January 1999 were deferred by the
Partnership at December 31, 1998. Realized gains of $600,000 on closed
contracts relating to January 1998 were deferred by the Partnership at December
31, 1997. Cash flows related to natural gas hedging are reported as cash flows
from operating activities.

During 1998, 1997 and 1996, natural gas forward pricing activities reduced the
Partnership's natural gas costs by $5.9 million, $25.6 million and $37.1
million, respectively, compared with spot market natural gas prices.

10. OTHER FINANCIAL INFORMATION

Fair values of financial instruments - The following methods and assumptions
were used by the Partnership in estimating its fair value disclosures for
financial instruments:

Cash and cash equivalents - The carrying amounts reported in the balance
sheet for cash and cash equivalents approximate their fair values.

Long-term debt and capital lease obligations - The carrying amounts of the
Partnership's borrowings under long-term debt agreements and capital lease
obligations approximate fair value.

Off-balance-sheet instruments - Fair values for the Partnership's natural
gas swaps and options are based on contract prices in effect at December 31,
1998 and December 31, 1997. The unrealized gain (loss) on these contracts is
disclosed in Note 9.

CONCENTRATION OF CREDIT RISK - The Partnership 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. Credit risk related to trade
receivables has also been minimized as a result of the accounts receivable
securitization agreement entered into during 1996.

Short-term cash investments, held as a demand deposit with an affiliate, may be
placed with well-capitalized, high quality financial institutions and in short
duration corporate and government debt securities funds or utilized for other
corporate purposes.

MAJOR CUSTOMERS - For the years ended December 31, 1998, 1997 and 1996, sales to
Terra totaled $26.3 million, $41.0 million and $41.4 million, or 10.5%, 12.3%
and 11.4%, respectively, of the Partnership's sales.
