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 future 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

7

losses associated with settled nitrogen derivative contracts are classified as revenue. The Partnership classifies amounts paid by customers for shipping and handling as revenue.

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 paid by customers for shipping and handling 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.

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.

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.

8

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 Partnership Agreement.

In the first three months of 2007, the Partnership paid $18.3 million in cash distributions to its partners. In the first three months of 2006 the Partnership did not pay any cash distributions.

At March 31, 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-month periods ended March 31, 2007 and 2006:

9

	Three Months Ended
	March 31,
(in thousands, except per-share amounts)	2007		2006
Basic income (loss) per limited Partnership unit computation:
Net income (loss) allocable to limited Partners’ interest	$	34,977	$	(2,413	)
Weighted average units outstanding		18,686		18,686
Net income (loss) per limited Partnership unit	$	1.87	$	(0.13	)

There were no dilutive Partnership units outstanding for the three-month periods ended March 31, 2007 and 2006.

4. Inventories

Inventories consisted of the following:

	March 31,		December 31,		March 31,
(in thousands)	2007		2006		2006
Materials and supplies	$	8,820	$	7,925	$	7,905
Finished goods		24,845		14,784		37,947
Total	$	33,665	$	22,709	$	45,852

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:

10

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.

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 March 31, 2007, December 31, 2006 and March 31, 2006:

	Other		Accrued
	Current		Current			Net
(in thousands)	Assets		Liabilities			Asset (Liability)
March 31, 2007	$	4,052	$	(2,434	)	$	1,618
December 31, 2006		1,529		(8,052	)		(6,523	)
March 31, 2006		2,601		(5,997	)		(3,396	)

Certain derivatives outstanding at March 31, 2007 and 2006, which settled during April 2007 and 2006, respectively, are included in the position of open natural gas derivatives in the table above. The April 2007 derivatives settled for an approximate $0.4 million loss. All open derivatives will settle during the next 12 months.

At March 31, 2007, the Partnership determined that certain derivative contracts were ineffective hedges for accounting purposes and recorded a credit of $1.6 million to cost of sales for the

11

three-month period ending March 31, 2007. Derivatives outstanding at March 31, 2006 included a loss of $3.4 million that was recorded as an ineffective position and charged to cost of sales for the three-month period ending March 31, 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.

The activity related to accumulated other comprehensive income (loss) for the three month periods ended March 31, 2007 and 2006 is:

(in thousands)	2007			2006
Beginning accumulated (loss)	$	(6,179	)	$	(5,949	)
Reclassification into earnings		36			20,268
Net change associated with current period hedging transactions		6,156			(14,319	)
Ending accumulated gain (loss)	$	13		$	¾

All of the accumulated gain recorded above will be reclassified into earnings during the next twelve-month period ending March 31, 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 March 31, 2007, the Partnership had no 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-month period ending March 31, 2007, the Partnership recognized a loss of $0.9 million on nitrogen forward derivative instruments. For the three-month period ending March 31, 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 5.61% at March 31, 2007). Under the credit facility, the Partnership may borrow an amount

12

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 March 31, 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 prioritized 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 and requirements of SFAS 157 are effective for the Company in 2008 first quarter and the Company 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

13

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 plants. 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.

The $32.7 million, or 34%, increase in revenues was primarily due to approximately 35% increase in both ammonia and UAN sales volumes, a 4% increase in UAN prices offset by a 13% decrease in ammonia prices.

The increase in volumes and UAN prices is due to increased demand for nitrogen products primarily as a result of increased corn prices as compared to 2006. Ammonia prices decreased due to the lower cost of natural gas, however, UAN pricing increased due to increased demand for the UAN product.

The 2007 first quarter gross profit was $37.4 million, which was $38.0 million more than the 2006 first quarter. Increased sales volumes raised 2007 first quarter gross profit by approximately $9.5 million as compared to the 2006 first quarter. The 2007 first quarter natural gas costs decreased $29.0 million from the 2006 first quarter. Natural gas costs purchased by the Partnership, including the effects of forward price contracts, during the 2007 and 2006 first quarters were $6.39 per MMBtu and $9.75 per MMBtu, respectively.

Capital resources and liquidity

Operating activities for the first three months of 2007 generated $54.8 million of cash, comprised of $37.5 million of cash from operations and $17.2 million from changes in current assets and liabilities. Cash from changes in current assets and liabilities represent seasonal fluctuations to working capital balances and included $21.3 million increase to customer deposits balance during the period, which are expected to be fulfilled primarily during second quarter 2007.

Capital expenditures of $1.3 million during the first three months of 2007 were primarily to fund replacement and stay-in-business additions to plant and equipment.

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 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 March 31, 2007, the Partnership had borrowing availability of $50 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 million, it is required to have generated $25 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 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.

Quarterly distributions to the partners are based on Available Cash for the quarter as defined in the 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. Distributions paid to the partners for the three-month period ended March 31, 2007 were $18.3 million. There were no distributions for the period ended March 31, 2006.

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 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

16

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.

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 March 31, 2007 to cover approximately 16% 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.

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, including employee injury claims. 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 2007 as compared to the risk factors identified in the Partnership’s 2006 Form 10-K.
