Notes to Consolidated Financial Statements (Unaudited)

1.      Financial Statement Presentation

Basis of Presentation

The condensed consolidated financial statements contained herein should be read in conjunction with the consolidated financial statements and notes thereto contained in the Terra Nitrogen Company, L.P. (“TNCLP”) Annual Report on Form 10-K for the year ended December 31, 2006. TNCLP and its operating partnership subsidiary, Terra Nitrogen, Limited Partnership (the “Operating Partnership”), are referred to herein, collectively, as the “Partnership”.

The accompanying unaudited condensed consolidated financial statements reflect all adjustments, which are, in the opinion of management, necessary for the fair statement of the results for the periods presented. All of these adjustments are of a normal and recurring nature. Results for the quarter are not necessarily indicative of future financial results of the Partnership.

Derivatives and Financial Instruments

The Partnership accounts for derivatives in accordance with Statement of Financial Accounting Standards (“SFAS”) No. 133, Accounting for Derivative Instruments and Hedging Activities, which requires that derivatives be reported on the balance sheet at fair value and, if the derivative is not designated as a hedging instrument, changes in fair value must be recognized in earnings in the period of change. If the derivative is designated as a hedge and to the extent such hedge is determined effective, changes in fair value are either (a) offset by the change in fair value of the hedged asset or liability or (b) reported as a component of accumulated other comprehensive income (loss) in the period of change, and subsequently recognized in the determination of net income in the period that the offsetting hedged transaction occurs.

Terra Industries Inc. and its subsidiaries (“Terra”) enter into derivative instruments with counterparties for the Partnership’s operations. When Terra enters into a derivative instrument for the Partnership’s operations, the Partnership simultaneously enters into a derivative instrument with Terra as the counterparty. The terms of the derivative instruments between the Partnership and Terra are identical to the terms of the derivative instruments between Terra and Terra’s counterparty. The types of derivative instruments entered into include futures contracts, swap agreements, put and call options to cap or fix prices for a portion of the Partnership’s natural gas production requirements. Terra may also enter into similar derivative instruments to fix or set floor prices for a portion of the Partnership’s nitrogen sales volumes.

Revenue Recognition

Revenue is recognized when persuasive evidence of a transaction exists, delivery has occurred, the price is fixed or determinable, no obligations remain and collectibility is probable. The Partnership classifies any discounts and trade allowances as a reduction in revenue. Gains or losses associated with settled nitrogen derivative contracts are classified as revenue. The Partnership classifies amounts directly or indirectly billed to its customers for shipping and handling as revenue.

7

Cost of Sales

The cost of manufacturing fertilizer products is recorded when the fertilizer products are sold and revenue is recognized. The Partnership classifies amounts directly or indirectly billed for delivery of products to its customers or its terminals as cost of sales. Premiums paid for option contracts are deferred and recognized in cost of sales in the month to which the related derivative transactions are settled. Realized gains and losses on derivatives activities are recognized in cost of sales.

Inventories

Inventories are stated at the lower of average cost or estimated net realizable value. The Partnership performs a monthly analysis of its inventory balances to determine if the carrying amount of inventories exceeds its net realizable value. The analysis of estimated realizable value is based on customer orders, market trends and historical pricing. If the carrying amount exceeds the estimated net realizable value, the carrying amount is reduced to the estimated net realizable value.

Production costs include the cost of direct labor and materials, depreciation and amortization, and overhead costs related to manufacturing activities. The cost of inventories is determined using the first-in, first-out method.

The Partnership estimates a reserve for obsolescence and excess of its materials and supplies inventory. Inventory is stated net of the reserve.

Impairment of Long-Lived Assets

The Partnership reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If the sum of the undiscounted future cash flows expected to result from the use of the asset is less than the carrying amount of the asset, an impairment loss is recognized based on the difference between the carrying amount and the fair value of the asset.

Natural Gas Futures, Swaps, Options and Basis Swaps

The estimated fair value of each class of derivatives is based on published referenced prices and quoted market prices from brokers.

8

Cash and Cash Equivalents

The Partnership classifies cash and short-term investments with an original maturity of three months or less as cash and cash equivalents. Demand deposits with affiliate are not classified in cash and cash equivalents.

Demand Deposits with Affiliate

Partnership cash receipts are generally received by Terra Capital, Inc., (“Terra Capital”) the indirect parent of the General Partner. Cash receipts, net of cash payments made by Terra Capital, are transferred to the Partnership from Terra Capital on a weekly basis. As a result of this cash collection and distribution arrangement, Terra Capital is a creditor to the Partnership.

Use of Estimates in Preparation of the Financial Statements

The preparation of financial statements in conformity with accounting principles generally accepted in the United States 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 reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

2.      Agreement of Limited Partnership

The Partnership makes quarterly cash distributions to Unitholders and the General Partner in an amount equal to 100% of its “Available Cash” as defined in the Agreement of Limited Partnership. Available Cash is defined generally as all cash receipts less all cash disbursements, adjusted for changes in certain reserves that the General Partner reasonably determines necessary.

The Limited Partners receive 99% of the Available Cash and 1% is distributed to the General Partner, except when cumulative distributions of Available Cash exceed specified target levels above the Minimum Quarterly Distribution (“MQD”) of $0.605 per unit. Under such circumstances, the General Partner is entitled, as an incentive, to larger percentage interests. As of September 30, 2007, the cumulative shortfall on quarterly distributions to holders of Common Units that must be paid before the General Partner receives an incentive payment was $152.9 million, or $8.18 per unit.

When cumulative distributions of Available Cash exceed specified target levels above the MQD, the General Partner’s percentage interest in the Partnership’s distributions of Available Cash at various levels follows:

Incremental Distribution	Percentage of Incremental Distribution
per Common Unit	to General Partner
Less than $0.715	1%
$0.715-$0.825	15%
$0.825-$1.045	25%
Greater than $1.045	50%

9

On October 25, 2007, the Partnership announced a $2.10 per unit distribution to be paid during the 2007 fourth quarter. As a result of this distribution, the pro forma cumulative shortfall that must be paid before the General Partner affiliate receives an incentive payment as of December 31, 2007 is anticipated to be approximately $125.0 million, or $6.69 per unit.

The General Partner is required to remit the majority of cash distributions it receives from the Partnership in excess of its one percent Partnership equity interest to an affiliated company.

In the first nine months of 2007, the Partnership paid $104.6 million in cash distributions to its partners. In the first nine months of 2006 the Partnership paid $17.4 million in cash distributions to its partners.

At September 30, 2007, the General Partner and its affiliates owned 75.3% of the Partnership’s outstanding units. When less than 25% of the issued and outstanding units are held by non-affiliates of the General Partner, the Partnership, at the General Partner’s sole discretion, may call, or assign to the General Partner or its affiliates, its right to acquire all such outstanding units held by non-affiliated persons. If the General Partner elects to acquire all outstanding units, the Partnership is required to 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 20 trading days’ closing prices as of the date five days before the purchase is announced and 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. Additional purchases of common units by the General Partner may be restricted under the terms of Terra’s bank credit agreement as described therein.

3.      Net Income per Limited Partnership Unit

Basic income per unit data is based on the weighted-average number of Partnership Units outstanding during the period. Diluted income per unit data is based on the weighted-average number of Partnership Units outstanding and the effect of all dilutive potential common units.

The following table provides the components of basic income per unit for the three- and nine-month periods ended September 30, 2007 and 2006:

	Three Months Ended				Nine Months Ended
	September 30,				September 30,
(in thousands, except per-unit amounts)	2007		2006		2007		2006
Basic income (loss) per limited Partnership unit computation:
Net income allocable to limited Partners’ interest	$	45,155	$	13,584	$	136,618	$	28,363
Weighted average units outstanding		18,686		18,686		18,686		18,686
Net income per limited Partnership unit	$	2.42	$	0.73	$	7.31	$	1.52

There were no dilutive Partnership units outstanding for the three- and nine-month periods ended September 30, 2007 and 2006.

10

4.      Inventories

Inventories consisted of the following:

	September 30,		December 31,		September 30,
(in thousands)	2007		2006		2006
Materials and supplies	$	7,737	$	7,925	$	9,625
Finished goods		22,750		14,784		16,216
Total	$	30,487	$	22,709	$	25,841

Inventory is valued at actual first in, first out cost. Costs include raw material, labor and overhead.

5.      Derivative Financial Instruments

The Partnership manages risk using derivative financial instruments for changes in natural gas supply prices and changes in nitrogen prices. Derivative financial instruments have credit risk and market risk.

Terra enters into derivative instruments with counterparties for the Partnership’s operations. When Terra enters into a derivative instrument for the Partnership’s operations, the Partnership simultaneously enters into a derivative instrument with Terra as the counterparty. The terms of the derivative instruments between the Partnership and Terra are identical to the terms of the derivative instruments between Terra and Terra’s counterparty. Terra will not enter into transactions with a counterparty if the additional transaction will result in credit exposure exceeding $20 million. The credit rating of counterparties may be modified through guarantees, letters of credit or other credit enhancement vehicles.

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

Natural gas supplies to meet production requirements at the Partnership’s production facilities are purchased at market prices. Natural gas market prices are volatile and the Partnership effectively hedges a portion of its natural gas production requirements and inventory through the use of futures contracts, swaps and options. These contracts reference physical natural gas prices or approximate NYMEX futures contract prices. Contract physical prices are frequently based on prices at the Henry Hub in Louisiana, the most common and financially liquid location of reference for financial derivatives related to natural gas. However, natural gas supplies for the Partnership’s production facilities are purchased at locations other than Henry Hub, which often creates a location basis differential between the contract price and the physical price of natural gas. Accordingly, the use of financial derivatives may not exactly offset the changes in the price of physical gas. The contracts are traded in months forward and settlement dates are scheduled to coincide with gas purchases during that future period.

11

A swap is a contract between the Partnership and a third party to exchange cash based on a designated price. Option contracts give the holder the right to either own or sell a futures or swap contract. The futures contracts require maintenance of cash balances generally 10% to 20% of the contract value and option contracts require initial premium payments ranging from 2% to 5% of contract value. Basis swap contracts require payments to or from the Partnership for the amount, if any, that monthly published gas prices from the source specified in the contract differ from the prices of a NYMEX natural gas futures during a specified period. There are no initial cash requirements related to the swap and basis swap agreements.

The following summarizes the position of open natural gas derivative contracts at September 30, 2007, December 31, 2006 and September 30, 2006:

	Other		Accrued
	Current		Current			Net
(in thousands)	Assets		Liabilities			Asset (Liability)
September 30, 2007	$	2,867	$	(14,041	)	$	(11,174	)
December 31, 2006		1,529		(8,052	)		(6,523	)
September 30, 2006		1,868		(8,938	)		(7,070	)

Certain derivatives outstanding at September 30, 2007 and 2006, which settled during October 2007 and 2006, respectively, are included in the position of open natural gas derivatives in the table above. The October 2007 derivatives settled for an approximate $4.0 million loss. All open derivatives will settle during the next 12 months.

At September 30, 2007, the Partnership determined that certain derivative contracts were ineffective hedges for accounting purposes and recorded a credit of $0.2 million and $1.2 million to cost of sales for the three- and nine-month periods ending September 30, 2007, respectively. Derivatives outstanding at September 30, 2006 included a charge of $0.7 million and a credit of $0.2 million to cost of sales for the three- and nine-month periods ending September 30, 2006.

The effective portion of gains and losses on settlement of these contracts that qualify for hedge treatment are carried as accumulated other comprehensive income (loss) and are credited or charged to cost of sales in the month in which the hedged transaction settles. Gains and losses on the contracts that do not qualify for hedge treatment are credited or charged to cost of sales based on the positions’ fair value. 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.

12

The activity related to accumulated other comprehensive income (loss) for the nine month periods ended September 30, 2007 and 2006 is:

(in thousands)	2007			2006
Beginning accumulated (loss)	$	(6,179	)	$	(5,949	)
Reclassification into earnings		13,160			22,235
Net change associated with current period hedging transactions		(19,049	)		(22,283	)
Ending accumulated loss	$	(12,068	)	$	(5,997	)

All of the accumulated loss recorded above will be reclassified into earnings during the next twelve-month period ending September 30, 2008.

At times, the Partnership also uses forward derivative instruments to fix or set floor prices for a portion of its nitrogen sales volumes. At September 30, 2007, the Partnership had open contracts covering nitrogen solutions. When outstanding, the nitrogen solution contracts do not qualify for hedge treatment due to inadequate trading history to demonstrate effectiveness. Consequently, these contracts are marked-to-market and unrealized gains or losses are reflected in revenue in the statement of operations. For the three- and nine-month periods ending September 30, 2007, the Partnership recognized a loss of $0.7 million and $2.6 million, respectively, on nitrogen forward derivative instruments. For the three-and nine-month periods ending September 30, 2006, there were no gains or losses on nitrogen forward derivative instruments.

6.      Revolving Credit Facility

In the first quarter of 2007, the Partnership amended the $50.0 million revolving credit facility to extend the expiration date to January 31, 2012. The revolving credit facility bears interest at a variable rate plus a margin (London Interbank Offer Rate (LIBOR) plus 175 basis points, or 6.88% at September 30, 2007). Under the credit facility, the Partnership may borrow an amount generally based on eligible cash balances, 85% of eligible accounts receivable and 60% of eligible finished goods inventory, less outstanding letters of credit. The Partnership’s borrowings under the credit facility are secured by substantially all of its working capital. The agreement also requires the Partnership to adhere to certain limitations on additional debt, capital expenditures, acquisitions, liens, asset sales, investments, prepayments of subordinated indebtedness, changes in lines of business and transactions with affiliates. At September 30, 2007, the Partnership had $50.0 million of borrowing availability, and, there were no outstanding borrowings or letters of credit under the facility.

7.      New Accounting Pronouncements

In September 2006, the FASB issued SFAS 157, Fair Value Measurements, (SFAS 157). SFAS 157 is definitional and disclosure oriented and addresses how companies should approach measuring fair value when required by generally accepted accounting principles (GAAP); it does not create or modify any current GAAP requirements to apply fair value accounting. SFAS 157 provides a single definition for fair value that is to be applied consistently for all accounting applications, and also generally describes and prioritizes according to reliability the methods and input used in valuations. SFAS 157 prescribes various disclosures about financial statement categories and amounts which are measured at fair value, if such disclosures are not already specified elsewhere in GAAP. The new measurement and disclosure requirements of SFAS 157 are effective for the Partnership in 2008 first quarter and the Partnership expects no significant impact from adopting the Standard.

In February 2007 the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards (SFAS) 159, The Fair Value Option for Financial Assets and Financial Liabilities (SFAS 159). SFAS 159 permits entities to choose to measure many financial instruments and certain other items at fair value at specified election dates. SFAS 159 is effective for the Partnership beginning in the first quarter of 2008. The Partnership is currently assessing the impact SFAS 159 may have on its financial statements.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Introduction

The Partnership produces and markets nitrogen products for use in agricultural and industrial markets. Nitrogen is a commodity chemical and prices are established based on global supply and demand conditions. The nitrogen products industry has cycles of oversupply, resulting in lower prices and idled capacity, followed by supply shortages, resulting in high selling prices and higher industry-wide production rates. Natural gas is the most significant raw material in the production of nitrogen products. To be viable under these market conditions, a producer must be among the low-cost producers to markets it serves and have a financial position that can sustain it during periods of oversupply.

Imports, most of which are produced at facilities with access to fixed-price natural gas supplies, account for a significant portion of U.S. nitrogen product supply. Imported products’ natural gas costs have been and could continue to be substantially lower than the delivered cost of natural gas to the Partnership’s facilities. Offshore producers are most competitive in regions close to the point of entry for imports, including the Gulf Coast and East Coast.

The Partnership’s sales volumes are primarily dependent upon the operating rates for its Verdigris plant. The Partnership may purchase product from other manufacturers or importers for resale, however, historic gross margins on those volumes are rarely significant. Profitability and cash flows from the operations are affected by the ability to manage costs and expenses (other than natural gas), most of which do not materially change for different levels of production or sales. Other factors affecting operating results include the level of planted acres, transportation costs, weather conditions (particularly during the planting season), grain prices and other variables described in Item 1 “Business” and Item 2 “Properties” sections of the Partnership’s most recent Form 10-K filing with the Securities and Exchange Commission.

Dependence on Terra Industries

The Partnership is dependent on Terra Industries Inc. (“Terra”) in a number of respects. Terra provides all of the Partnership’s management, natural gas purchasing and hedging, selling and administrative services and operates its facilities through its wholly-owned subsidiary Terra Nitrogen GP Inc., the Partnership’s General Partner. Terra and its wholly-owned subsidiaries have more debt and debt service requirements than the Partnership. Although Terra is affected by most of the factors that affect the Partnership, its higher level of debt could put a greater risk on Terra in the event of adverse business conditions. The Partnership’s results of operations and financial condition might be materially adversely affected by financial difficulties at Terra, default by it or its subsidiaries on their debt or their bankruptcy. For additional information concerning Terra, refer to Terra’s filings with the Securities and Exchange Commission on Form 10-K, Forms 10-Q and current reports on Form 8-K.

Three months ended September 30, 2007 compared with
three months ended September 30, 2006

Volumes and prices for the three-month periods ended September 30, 2007 and 2006 are:

	2007				2006
	Volumes		Unit Price		Volumes		Unit Price
	(000 tons)		($/ton)*		(000 tons)		($/ton)*
Ammonia		57	$	367		49	$	301
UAN		493	$	204		522	$	125

*After deducting outbound freight costs

Revenues for the 2007 third quarter were $133.0 million, compared to $91.8 million for the 2006 third quarter. The $41.2 million, or 45%, increase in revenues was primarily due to an increase in ammonia sales volumes and price of 16% and 22%, respectively, and a 63% increase in UAN prices. The higher prices and ammonia volumes result from increased and earlier demand for nitrogen products for corn and wheat plantings.

The 2007 third quarter gross profit was $46.7 million, which was $31.2 million more than the 2006 third quarter. As compared to the 2006 third quarter, 2007 gross profits increased approximately $42.3 million due to higher prices, offset by higher natural gas costs of $9.1 million. Natural gas costs purchased by the Partnership, including the effects of forward price contracts, during the 2007 and 2006 third quarters were $7.02 per MMBtu and $5.96 per MMBtu, respectively.

Nine months ended September 30, 2007 compared with
nine months ended September 30, 2006

Volumes and prices for the nine-month periods ended September 30, 2007 and 2006 are:

	2007				2006
	Volumes		Unit Price		Volumes		Unit Price
	(000 tons)		($/ton)*		(000 tons)		($/ton)*
Ammonia		221	$	370		168	$	367
UAN		1,698	$	188		1,521	$	139

*After deducting outbound freight costs

Revenues for the nine months ended September 30, 2007 increased $131.6 million, or 43%, compared with the same 2006 period primarily due to increased sales volumes and higher prices. The higher volumes and prices were due to stronger demand for nitrogen products primarily as a result of increased planted corn acreage as compared to 2006.

The 2007 first nine months gross profit was $147.4 million, which was $113.6 million more than the 2006 first nine months. Increased sales volumes and sales prices raised 2007 first nine months gross profit by approximately $18.5 million and $74.8 million, respectively, as compared to the 2006 first nine months. The 2007 first nine months natural gas costs decreased $23.5 million from the 2006 first nine months. Natural gas costs purchased by the Partnership, including the effects of forward price contracts, during the 2007 and 2006 first nine months, were $6.70 per MMBtu and $7.32 per MMBtu, respectively.

16

Operating expenses for the first nine months of 2007 increased $6.8 million primarily due to annual and long-term incentive plans as compared to the first nine months of 2006.

Capital resources and liquidity

Operating activities for the first nine months of 2007 generated $151.9 million of cash, comprised of $150.3 million of cash from operating activities, $1.6 million used to fund working capital increases. The primary working capital needs were to fund $7.8 million related to increased inventory levels, offset by $4.4 million of customer prepayment reductions for seasonal customer shipments.

Capital expenditures of $5.4 million during the first nine months of 2007 were primarily to fund replacement and stay-in-business additions to plant and equipment. Plant turnaround costs represent cash used for the periodic scheduled maintenance of the Partnership’s continuous process production facilities. The Partnership funded $13.1 million of plant turnaround during the first nine months of 2007.

The Partnership’s principal funding needs are to support its working capital and capital expenditures. The Partnership intends to fund its needs primarily from cash provided by operating activities and, to the extent required, from funds borrowed under the Partnership’s $50.0 million revolving bank credit facility.

In the first quarter of 2007, the Partnership amended the $50.0 million revolving credit facility to extend the expiration date to January 31, 2012. Under the credit facility, the Partnership may borrow an amount generally based on eligible cash balances, 85% of eligible accounts receivable and 60% of eligible finished goods inventory, less outstanding letters of credit. The Partnership’s borrowings under the credit facility are secured by substantially all of its working capital. At September 30, 2007, the Partnership had borrowing availability of $50.0 million and had no outstanding borrowings or letters of credit under the facility. Management expects the facility to be adequate to meet the Partnership’s operating cash needs.

Under the credit facility, the Partnership is subject to the covenants which impose certain limitations on additional debt, capital expenditures, acquisitions, liens, asset sales, investments, prepayments of subordinated indebtedness, changes in lines of business and transactions with affiliates. In addition, if the Partnership’s aggregate borrowing availability falls below $10.0 million, it is required to have generated $25.0 million of operating cash flows or earnings before interest, income taxes, depreciation, amortization and other non-cash items as defined in the credit facility for the preceding four quarters. The Partnership is also required to maintain a minimum aggregate unused borrowing availability of $5.0 million at all times.

The Partnership’s ability to continue to meet the covenants under the credit facility in the future will depend on market conditions, operating cash flows, working capital needs, receipt of customer prepayments and trade credit terms. Failure to meet these covenants, or to obtain a waiver from the lenders, would result in a default by the Partnership such that all outstanding amounts could become immediately due and payable and the Partnership would be unable to borrow additional amounts under the credit facility. Because access to adequate bank facilities may be critical to funding the Partnership’s operating cash needs and purchase of financial derivatives to manage the Partnership’s exposure to natural gas commodity price risk, any default or termination of the revolving bank credit facility could have a material adverse effect on the Partnership.

17

Quarterly distributions to the partners are based on Available Cash for the quarter as defined in the 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 reasonably determines necessary.

The Limited Partner receives 99% of the Available Cash and 1% is distributed to the General Partner, except when cumulative distributions of Available Cash exceed specified target levels above the Minimum Quarterly Distribution (“MQD”) of $0.605 per unit. Under such circumstances, the General Partner is entitled, as an incentive, to larger percentage interests. As of September 30, 2007, the cumulative shortfall on quarterly distributions to holders of Common Units that must be paid before the General Partner receives an incentive payment was $152.9 million, or $8.18 per unit.

The General Partner’s percentage interest in the Partnership’s distributions of Available Cash at various levels follows:

Incremental Distribution	Percentage of Incremental Distribution
per Common Unit	to General Partner
Less than $0.715	1%
$0.715-$0.825	15%
$0.825-$1.045	25%
Greater than $1.045	50%

On October 25, 2007, the Partnership announced a $2.10 per unit distribution to be paid during the 2007 fourth quarter. As a result of this distribution, the pro forma cumulative shortfall that must be paid before the General Partner affiliate receives an incentive payment as of December 31, 2007 is anticipated to be approximately $125.0 million, or $6.69 per unit.

The General Partner is required to remit the majority of cash distributions it receives from the Partnership in excess of its one percent Partnership equity interest to an affiliated company.

Distributions paid to the partners for the nine-month period ended September 30, 2007 were $104.6 million. Distributions paid to the partners for the period ended September 30, 2006 were $17.4 million.

At September 30, 2007, the General Partner and its affiliates owned 75.3% of the Partnership’s outstanding units. When less than 25% of the issued and outstanding units are held by non-affiliates of the General Partner, the Partnership, at the General Partner’s sole discretion, may call, or assign to the General Partner or its affiliates, its right to acquire all such outstanding units held by non-affiliated persons. If the General Partner elects to acquire all outstanding units, the Partnership is required to 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 20 trading days’ closing prices as of the date five days before the purchase is announced and 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. Additional purchases of common units by the General Partner may be restricted under the terms of Terra’s bank credit agreement as described therein.

18

Partnership cash receipts are generally received by Terra Capital, Inc., (“Terra Capital”) the indirect parent of the General Partner. Cash receipts, net of cash payments made by Terra Capital, are transferred to the Partnership from Terra Capital on a weekly basis. As a result of this cash collection and distribution arrangement, Terra Capital is a creditor to the Partnership.

There were no material changes outside the ordinary course of business to the Company’s contractual obligations or off-balance sheet arrangements presented in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of the Annual Report on Form 10-K for the period ended December 31, 2006.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Partnership’s operations are significantly affected by the price of natural gas. It employs derivative commodity instruments related to a portion of its natural gas requirements (primarily futures, swaps and options) for the purpose of managing exposure to commodity price risk in the purchase of natural gas. Changes in the market value of these derivative instruments are expected to have a high correlation to changes in the spot price of natural gas. For more information about how the Partnership manages specific risk exposures, refer to its most recent Annual Report on Form 10-K (which is on file with the Securities and Exchange Commission), Item 7A “Quantitative and Qualitative Disclosures about Market Risk” and Note 6 – Derivative Financial Instruments contained in Item 8 of the Partnership’s 2006 form 10-K. There were no material changes in the Company’s use of financial instruments during the quarter ended September 30, 2007.

The volume of natural gas hedged varies from time to time based on management’s judgment of market conditions, particularly natural gas prices and prices for nitrogen products. Management also considers the Partnership’s position related to forward fixed price sales contracts in determining the level of derivatives necessary. Contracts were in place at September 30, 2007 to cover approximately 38% of its natural gas requirements for the succeeding twelve months. The General Partner’s ability to manage the Partnership’s exposure to commodity price risk in the purchase of natural gas through the use of financial derivatives may be affected by limitations imposed by its bank agreement covenants.

19

ITEM 4. CONTROLS AND PROCEDURES

The Partnership’s Chief Executive Officer and Chief Financial Officer have concluded, based on their evaluation as of the end of the period covered by this report, that the Partnership’s disclosure controls and procedures are effective to ensure that information required to be disclosed in the reports that the Partnership files or submits under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported, within the time periods specified in the Securities and Exchange Commission’s rules and forms.

There were no significant changes in the Partnerships’ internal control over financial reporting that occurred during the most recent quarter that have materially affected, or are reasonably likely to materially affect, the Partnerships’ internal control over financial reporting.

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: changes in the financial markets, general economic conditions within the agricultural industry, competitive factors and price changes (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 Partnership’s Securities and Exchange Commission filings, in particular Item 1A “Risk Factors” and the “Factors that Affect Operating Results” section of its most recent Form 10-K.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

The Partnership is involved in various claims and legal actions arising in the ordinary course of business. In the opinion of management, the ultimate disposition of these matters will not have a material adverse effect on the Partnership’s consolidated financial position, results of operations or liquidity and the likelihood that a loss contingency will occur in connection with these claims is remote.

ITEM 1A. RISK FACTORS

There were no significant changes in the Partnership’s risk factors during the third quarter of 2007 as compared to the risk factors identified in the Partnership’s 2006 Form 10-K.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

Exhibit 10.1

AMENDED AND RESTATED GENERAL AND ADMINISTRATIVE
SERVICES AGREEMENT REGARDING
SERVICES BY TERRA INDUSTRIES INC.

THIS AMENDED AND RESTATED GENERAL AND ADMINISTRATIVE SERVICES AGREEMENT (the “Agreement”) is entered into on October 23, 2007 (the “Effective Date”) by and between TERRA INDUSTRIES INC., a Maryland corporation (“Terra”), TERRA NITROGEN CORPORATION, a Delaware corporation (the “Prior General Partner”) and TERRA NITROGEN GP INC., a Delaware corporation (the “General Partner”).

R E C I T A L S

WHEREAS, Terra and the Prior General Partner were parties to that certain General and Administrative Services Agreement Regarding Services By Terra Industries Inc., dated as of January 1, 1995 (the “Terra Services Agreement”).

WHEREAS, Terra and the Prior General Partner were parties to that certain General and Administrative Services Agreement Regarding Services By the Prior General Partner, dated as of January 1, 1995 (the “TNC Services Agreement”).

WHEREAS, in connection with a restructuring (the “Restructuring”) to create a bankrupt-remote entity to serve as general partner of Terra Nitrogen Company, L.P. (the “Partnership”) and Terra Nitrogen, Limited Partnership (the “Operating Partnership”, and with the Partnership, the “Partnerships”), the Prior General Partner transferred its general partner interest in the Partnerships to the New General Partner on September 1, 2005.

WHEREAS, immediately prior to the Restructuring, the Prior General Partner approved the restructuring of its outstanding general partner interest (the “GP Interest”) in the Partnership, constituting a 1/99ths GP Interest (the “MLP GP Interest”) and its outstanding GP Interest in the Operating Partnership, constituting a 1% GP Interest in the Operating Partnership (the “OLP GP Interest”) so that (i) the MLP GP Interest was changed into a 0.025/99ths GP Interest in the Partnership represented by 4,720 General Partner Units (the “Revised MLP GP Interest”) and a 0.975/99ths limited partner interest in the Partnership represented by 184,072 non-voting Class B Common Units and (ii) the OLP GP Interest was changed into a 0.025% GP Interest in the Operating Partnership (the “Revised OLP GP Interest”) and a 0.975% limited partner interest in the Operating Partnership.

WHEREAS, in connection with the Restructuring, Terra, the General Partner and the Prior General Partner entered into, as of September 1, 2005, the First Amendment to the General and Administrative Services Agreement Regarding Services By Terra Industries Inc., such that the General Partner would become a party to the Terra Services Agreement.

WHEREAS, in connection with the Restructuring, Terra, the General Partner and the Prior General Partner entered into, as of September 1, 2005, the First Amendment to the General and Administrative Services Agreement Regarding Services By Terra Nitrogen Corporation, such that the General Partner would become a party to the TNC Services Agreement.

WHEREAS, Terra and/or one of its Affiliates is able to provide certain of such services to the General Partner and the Partnership.

WHEREAS, Terra and the General Partner desire by their execution of this Agreement to evidence their understanding concerning the provision of certain such services by Terra to the General Partner and the Partnerships.

WHEREAS, this Agreement will amend and restate the Terra Services Agreement, as amended.

WHEREAS, this Agreement supersedes the TNC Services Agreement, as amended, and therefore the parties hereto desire to terminate the TNC Services Agreement, as amended.

WHEREAS, capitalized terms used herein but not defined shall have the meaning given them in the First Amended and Restated Agreement of Limited Partnership of the Partnership dated as of September 1, 2005 (the “Partnership Agreement”), as such agreement is in effect on the Effective Date to which reference is hereby made for all purposes of this Agreement.

THEREFORE, in consideration of the premises and covenants, conditions, and agreement contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

1. Term. Subject to the terms hereof, the term of this Agreement shall be from the Effective Date and extending for a period of one (1) year. Thereafter, the term shall be automatically extended for successive periods of one (1) year each, unless terminated by any party hereto at the end of such one year period upon at least ninety (90) days’ prior written notice to the other.

2. Services. During the term hereof, in exchange for the payment described herein, Terra agrees to provide, or cause one of its Affiliates to provide, to the General Partner and, as directed by the General Partner to the Partnership, certain selling, general and administrative services (the “Services”) in accordance with the terms of this Agreement. At Terra’s election, Terra may cause one or more of its Affiliates or third-party contractors (foreign or domestic) to provide the Services called for by this Agreement; provided, however, that Terra shall remain responsible for the provision of the Services in accordance with this Agreement. The Services provided hereunder shall be those described on Exhibit A attached hereto.

3. Quality of Service. The parties agree that the Services to be provided hereunder shall be of the same general quality as services provided by Terra under the Terra Services Agreement and as previously provided under the TNC Service Agreement. If the General Partner decides to use a Service described on Exhibit A that has been caused by Terra to be provided by a third party provider (“Outsourced”) which is not an Affiliate of Terra, the parties hereto agree that such Service will be of a quality provided for in the agreement between Terra and the third-party provider. Terra alone may determine whether or not to Outsource a Service. In general, Terra will use the same standards it would use for itself or its other Affiliates in determining whether or not to Outsource a Service.

4. Payment. In consideration for the performance of the Services by Terra, the General Partner or the Partnership, in accordance with the following provisions, shall reimburse Terra, for (i) all reasonable and documented direct expenses actually incurred by Terra or its Affiliates relating to the Services provided hereunder to the General Partner or the Partnerships (“Direct Charges”), and (ii) a proportionate amount of all necessary and appropriate selling, general and administrative, overhead and other indirect costs and expenses relating to the Services provided by Terra and/or its Affiliates hereunder to the General Partner or the Partnerships, in each case pursuant to the expense allocation guidelines set out in Exhibit A attached hereto (“Indirect Charges,” and together with Direct Charges, “Charges”). The monthly charges shall be based upon estimated allocation rates that may be adjusted as warranted during the course of the year. Allocation true up calculations shall be performed as part of the Terra year end financial closing procedures using preliminary full year financial data.

5. Invoicing. The General Partner, on behalf of the Partnership, shall be charged on a monthly basis its share of selling expenses incurred by Terra. Supporting documentation of the monthly charges, prepared by Terra, is available for review by the General Partner upon request. The method of calculation of the General Partner’s share is reflected in Exhibit A attached hereto. The monthly charges shall be based upon estimated allocation rates that may be adjusted as warranted during the course of the year. Allocation true-up calculations shall be performed as part of the Terra year-end financial closing procedures using preliminary full year financial data.

6. Role of General Partner. The General Partner shall not request performance of any Services for the benefit of any entity other than for itself or for the Partnership. The General Partner represents and agrees that it will use the Services only in accordance with all applicable federal, state and local laws and regulations, and in accordance with the reasonable conditions, rules, regulations and specifications which may be set forth in any manuals, materials, documents or instructions furnished from time to time by Terra. Terra and its Affiliates reserve the right to take all actions, including termination of any particular Services, that they may reasonably believe to be necessary to assure compliance with applicable laws and regulations. Terra will notify the General Partner of the reasons for any such termination of Services.

7. Termination of TNC Services Agreement. The parties hereby agree that the TNC Services Agreement, as amended, is terminated.

8. Limited Warranty; Limitation of Liability. TERRA REPRESENTS THAT THE SERVICES PROVIDED HEREUNDER SHALL BE PROVIDED WITH REASONABLE DILIGENCE. EXCEPT AS SET FORTH IN THE IMMEDIATELY PRECEDING SENTENCE, TERRA MAKES NO (AND HEREBY DISCLAIMS AND NEGATES ANY AND ALL) REPRESENTIONS AND WARRANTIES, EXPRESS OR IMPLIED, INCLUDING THE WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE WITH RESPECT TO THE SERVICES RENDERED TO OR PRODUCTS OBTAINED HEREUNDER. FURTHERMORE, NO PARTY HERETO MAY RELY UPON ANY REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED, INCLUDING THE WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE MADE TO TERRA BY ANY PARTY PERFORMING SERVICES ON BEHALF OF TERRA OR ITS AFFILIATES HEREUNDER, UNLESS SUCH PARTY MAKES AN EXPRESS WRITTEN WARRANTY TO THE GENERAL PARTNER. THE GENERAL PARTNER AGREES THAT THE REMUNERATION TO BE PAID TO TERRA AND ITS AFFILIATES HEREUNDER FOR THE SERVICES TO BE PERFORMED REFLECT THIS LIMITATION OF LIABILITY AND DISCLAIMER OF WARRANTIES. IN NO EVENT SHALL TERRA, ITS AFFILAITES, OR ANY OTHER PERSON OR ENTITY BE LIABLE FOR ANY INDIRECT, SPECIAL OR CONSEQUENTIAL DAMAGES RESULTING FROM ANY ERROR IN THE PERFORMANCE OF SERVICES OR FROM THE BREACH OF THIS AGREEMENT, REGARDLESS OF THE FAULT OF TERRA OR ITS AFFILIATES, OR WHETHER WHOLLY, CONCURRENTLY, PARTIALLY, OR SOLELY NEGLIGENT.

9. Force Majeure. This Agreement shall not be terminated as a result of any failure of a party to perform any of its obligations hereunder if such failure is due to circumstances beyond its control (an “Event of Force Majeure”), including, but not limited to, any requisition by any government authority, act of war, terrorism, strike, boycott, lockout, picketing, riot, sabotage, civil commotion, insurrection, epidemic, pandemic, disease, act of God, fire, flood, accident, explosion, earthquake, storm, failure of public utilities or common carriers, mechanical failure, embargo, or prohibition imposed by any governmental body or agency having authority over the party, provided that such time as an Event of Force Majeure no longer exists, the respective obligations of the parties hereto shall be reinstated and this Agreement shall continue in full force and effect. The party affected by an Event of Force Majeure shall give prompt notice thereof to the other party hereto and each party shall use good faith efforts to minimize the duration and consequences of, and to eliminate, any such Event of Force Majeure.

10. Severability. In the event any portion of this Agreement shall be found by a court of competent jurisdiction to be unenforceable, that portion of the Agreement will be null and void and the remainder of the Agreement will be binding on the parties as if the unenforceable provisions had never been contained herein.

11. Relationship of the Parties. In all matters relating to this Agreement, each party hereto shall be solely responsible for the acts of its employees, and employees of one party shall not be considered employees of the other party. Except as otherwise provided herein, no party shall have any right, power or authority to create any obligation, express or implied, on behalf of any other party. Nothing in this Agreement is intended to create or constitute a joint venture or partnership between the parties hereto or persons referred to herein.

12. Assignment. No party shall have the right to assign its rights or obligations under this Agreement without the consent of the other parties.

13. Confidentiality. The General Partner shall keep and hold, and shall cause its officers, employees and other agents (including those of the Partnerships) to keep and hold, in strictest confidence, all confidential and/or proprietary information respecting, or in any way related to Terra and its Affiliates, and/or the business, operations, financial results and affairs of Terra and its Affiliates, whenever and however learned unless such confidential and/or proprietary information (i) becomes generally available to the public, provided this occurs by means other than the breach of this Section 13, (ii) was available on a non-confidential basis to the General Partner prior to its disclosure by Terra, (iii) becomes available to the General Partner on a non-confidential basis from a source other than Terra, provided that such source is not a party to a confidentiality agreement concerning such information, or (iv) is required to be disclosed pursuant to law or regulation. The provisions of this Section 13 shall survive for one (1) year any expiration or earlier termination of this Agreement.

14. Entire Agreement. This Agreement constitutes the entire agreement of the parties relating to the performance of the Services. All prior or contemporaneous written or oral agreements are merged herein.

15. Choice of Law. This Agreement shall be subject to and governed by the laws of the State of Delaware, excluding any conflicts-of-law rule or principle that might refer the construction or interpretation of this Agreement to the laws of another state.

16. Amendment or Modification. This Agreement may be amended or modified from time to time only by a written amendment signed by the parties hereto.

TERRA INDUSTRIES INC.
EXPENSE ALLOCATION

General

Terra Industries Inc. (“Terra”) shall incur or pay the selling, general and administrative expenses relating to Terra’s nitrogen and methanol operations, as well as the operations of the Partnerships, and allocate such expenses as described below.

Allocation Overview

1. Selling, general and administrative expenses incurred or paid by Terra that are specifically identifiable to the Partnership shall be charged directly to the Partnership. These direct expenses include, but are not limited to, board of director fees, filing fees, costs associated with K-1 administration and other similar direct expense items. Selling, general and administrative expenses that are specifically identifiable as non-Partnership related expenses shall not be included in the selling expense allocation.

2. Selling expenses incurred or paid by Terra (other than the direct charges described in paragraph 1 above) shall be allocated between the Partnership and Terra based on the one-factor formula described below. Selling expenses are generally categorized as relating to the following departments — Operating Administration, Ag Sales, Industrial Sales, Customer Service, Distribution and Supply. These department names may change from time to time.

3. General and administrative expenses incurred or paid by Terra (other than the direct charges described in paragraph 1 above) pertaining to Terra’s nitrogen operations shall be allocated between the Partnership and Terra based upon a three-factor formula described below. General and administrative expenses are generally categorized as relating to the following departments — Executive, Legal, Human Resources, Financial Services, Information Systems and Office Services. These department names may change from time to time.

One-Factor Allocation Formula

The one-factor formula referenced in the allocation process described above uses total revenues as the sole factor. A sample allocation formula is presented here for illustration purposes:

	Partnership			Terra			Total
Total revenue dollars (millions)	$	500		$	1250		$	1750
% to total		29	%		71	%		100	%

Three-Factor Allocation Formula

The three-factor formula referenced in the allocation process described above uses (1) headcount, (2) total revenues, and (3) net book value of property, plant and equipment as the allocation factors. Each allocation factor receives an equal weighting in calculating the allocation percentage for the various entities. A sample allocation formula is presented here for illustration purposes:

	Partnership			Terra			Total
Headcount		100			400			500
% to total		20	%		80	%		100	%
Total revenue dollars (millions)	$	500		$	1250		$	1750
% to total		29	%		71	%		100	%
Net book value — PPE (millions)	$	75		$	450		$	525
% to total		14	%		86	%		100	%
Allocation factor		21	%		79	%		100	%
(sum of %’s divided by 3)
