TERRA NITROGEN COMPANY, L.P.

Notes to Consolidated Financial Statements (Unaudited)

1.	Background and Basis of Presentation
	Terra Nitrogen Company, L.P. (TNCLP, our, we, or us) is a leading producer and marketer of wholesale nitrogen products made from natural gas. TNCLP and its operating partnership subsidiary, Terra Nitrogen, Limited Partnership (Operating Partnership), are referred to herein, collectively, as the “Partnership”. Our principal products are anhydrous ammonia (ammonia) and urea ammonium nitrate solutions (UAN), which we manufacture at our facility in Verdigris, Oklahoma. We operate in one principal industry segment — Nitrogen Products, which is based upon the guidance provided in Statement of Financial Accounting Standards (SFAS) 131, Disclosures about Segments of an Enterprise and Related Information (SFAS 131). As a wholesale nitrogen producer, we do not report industry segments in a separate disclosure because our only reportable industry segment is nitrogen.
	The accompanying unaudited condensed consolidated financial statements and notes thereto have been prepared in accordance with the requirements of the U.S. Securities and Exchange Commission for interim reporting. Our significant accounting policies are described in the notes to the consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2008. Management is responsible for the unaudited condensed consolidated financial statements included in this document. The condensed consolidated financial statements included in this document are unaudited, but in the opinion of management, include all adjustments necessary for fair presentation of the Partnership’s financial position, results of operations and cash flows for the periods presented.
2.	New Accounting Pronouncements
	In December 2007, the Financial Accounting Standards Board (FASB) issued SFAS 141R, Business Combinations (SFAS 141R), which changes the way we account for business acquisitions. SFAS 141R requires the acquiring entity in a business combination to recognize all (and only) the assets acquired and liabilities assumed in the transaction and establishes the acquisition-date fair value as the measurement objective for all assets acquired and liabilities assumed in a business combination. Certain provisions of SFAS 141R will, among other things, impact the determination of acquisition-date fair value of consideration paid in a business combination (including contingent consideration); exclude transaction costs from acquisition accounting; and change accounting practices for acquired contingencies, acquisition-related restructuring costs, in-process research and development, indemnification assets, and tax benefits. SFAS 141R became effective for the Partnership on January 1, 2009 and the adoption did not have an impact on our financial statements.
	In March 2008, the FASB issued SFAS 161, Disclosures about Derivative Instruments and Hedging Activities (SFAS 161). SFAS 161 is an amendment of SFAS 133, Accounting for Derivative Instruments and Hedging Activities (SFAS 133). To address concerns that the existing disclosure requirements of SFAS 133 do not provide adequate information, SFAS 161 requires enhanced disclosures about an entity’s derivative and hedging activities and thereby improves the transparency of financial reporting. SFAS 161 became effective for the Partnership on January 1, 2009 and we have included the additional disclosure information required by SFAS 161 within Note 6, Derivative Financial Instruments, of the Notes to the Consolidated Financial Statements.

7

	The FASB has issued Draft Abstract Emerging Issues Task Force (EITF) Issue 07-4, Application of the Two-Class Method under FASB Statement No. 128 to Master Limited Partnerships (EITF 07-4). EITF 07-4 specifies the treatment of earnings per unit calculations when incentive distribution rights exist. EITF 07-4 became effective for the Partnership on January 1, 2009 and did not have an impact on our financial statements.
	In April 2009, the FASB issued FASB Staff Position No. 107-1 (FSP FAS 107-1) and APB 28-1 (APB 28-1), which amends FASB Statement No. 107, Disclosures about Fair Value of Financial Instruments and APB Opinion No. 28, Interim Financial Reporting, to require disclosures about the fair value of financial instruments for interim reporting periods. FSP FAS 107-1 and APB 28-1 will be effective for interim reporting periods ending after June 15, 2009. We are currently evaluating the future impacts and disclosures of this staff positions.
	In April 2009, the FASB issued FASB Staff Position No. 157-4, Determining Whether a Market is not Active and a Transaction is not Distressed (FSP FAS 157-4), which provides additional guidance in accordance with FASB No. 157, Fair Value Measurements, when the volume and level of activity for the asset or liability has significantly decreased. FSP FAS 157-4 shall be effective for interim and annual reporting periods ending after June 15, 2009. We are currently evaluating the future impacts and disclosures of this staff position.
3.	Agreement of Limited Partnership
	We make quarterly distributions to our partners based on Available Cash (as defined in our Agreement of Limited Partnership) for the quarter. Available Cash is defined generally as all cash receipts less all cash disbursements, adjusted for changes in certain reserves established as Terra Nitrogen GP Inc. (the General Partner) determines in its reasonable discretion to be necessary. We paid distributions of $93.5 million to our partners in the first three months of 2009 and $84.0 million for the same period in 2008.
	We receive 99% of the Available Cash from the Operating Partnership and 1% is distributed to its general partner (who is also our General Partner). Cash distributions from the Operating Partnership generally represent the Operating Partnership’s Available Cash from operations. Our cash distributions are made 99.975% to Common Unitholders and Class B Common Unitholders and 0.025% to our General Partner except when cumulative distributions of Available Cash exceed specified target levels above the Minimum Quarterly Distributions (“MQD”) of $0.605 per unit. Under such circumstances, our General Partner is entitled, as an incentive, to larger percentage interests.

8

On April 21, 2009, we announced a $2.10 cash distribution per common limited partnership unit payable on May 27, 2009, to holders of record as of May 5, 2009. We have exceeded the cumulative MQD amounts and will distribute Available Cash as summarized in the following table:

	Income and Distribution Allocation
								Class B
	Target		Target		Common			Common			General
	Limit		Increment		Units			Units			Partner			Total
Minimum Quarterly Distribution	$	0.605	$	0.605		98.990	%		0.985	%		0.025	%		100.000	%
First Target		0.715		0.110		98.990	%		0.985	%		0.025	%		100.000	%
Second Target		0.825		0.110		85.859	%		0.985	%		13.156	%		100.000	%
Third Target		1.045		0.220		75.758	%		0.985	%		23.257	%		100.000	%
Final Target and Beyond		1.045		¾		50.505	%		0.985	%		48.510	%		100.000	%

	The General Partner is required to remit the majority of cash distributions it receives from the Partnership, in excess of its 1% Partnership equity interest, to an affiliated company.
	At March 31, 2009, the General Partner and its affiliates owned 75.3% of our outstanding units. When not more than 25% of our issued and outstanding units are held by non-affiliates of the General Partner, we, at the General Partner’s sole discretion, may call, or assign to the General Partner or its affiliates, our right to acquire all such outstanding units held by non-affiliated persons. If the General Partner elects to acquire all outstanding units, we are required to give at least 30 but not more than 60 days’ notice of our 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 Industries Inc.’s bank credit agreement as described therein.
4.	Net Income per Common Unit
	Basic and diluted income per Common Unit is based on the weighted-average number of Common Units outstanding during the period. The following table provides a reconciliation for basic and diluted income per Common Unit for the three-month periods ended March 31, 2009 and 2008:

	Three Months Ended
	March 31,
(in thousands, except per-unit amounts)	2009			2008
Basic income per Common Unit:
Net income	$	43,342		$	81,596
Less: Net income allocable to Class B Common Units		(423	)		(796	)
Less: Net income allocable to General Partner		(15,423	)		(8,096	)
Net income allocable to Common Units		27,496			72,704
Weighted average units outstanding		18,502			18,502
Net income per Common Unit	$	1.49		$	3.93

There were no dilutive Common Units outstanding for the three-month periods ended March 31, 2009 and 2008.

5.	Inventories
	Inventories consisted of the following:

	March 31,		December 31,		March 31,
(in thousands)	2009		2008		2008
Materials and supplies	$	9,665	$	10,708	$	8,405
Finished goods		28,204		46,499		30,428
Total	$	37,869	$	57,207	$	38,833

	Production costs include the cost of direct labor and materials, depreciation and amortization, and overhead costs related to manufacturing activities. We allocate fixed production overhead costs based on the normal capacity of our production facilities and unallocated overhead costs are recognized as expense in the period incurred. We determine the cost of inventories using the first-in, first-out method.
	Inventories are stated at the lower of cost or market. Market is defined as current replacement cost, except that market should not exceed the net realizable value and should not be less than net realizable value reduced by an allowance for an approximately normal profit margin. The cost of inventories is determined by using the first-in, first-out method. We perform a monthly analysis of our inventory balances to determine if the carrying amount of inventories exceeds our net realizable value. Our determination of estimated net 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.
	We estimate a reserve for obsolescence and excess of materials and supplies inventory. Inventory is stated net of the reserve.
6.	Derivative Financial Instruments
	In March 2008, the FASB issued SFAS 161, Disclosures about Derivative Instruments and Hedging Activities (SFAS 161). SFAS 161 is an amendment of SFAS 133, Accounting for Derivative Instruments and Hedging Activities (SFAS 133). SFAS 161 requires enhanced disclosures of an entity’s derivative and hedging activities and thereby improves the transparency of financial reporting. SFAS 161 became effective for the Partnership on January 1, 2009 and we have incorporated the additional disclosure information for SFAS 161 below.

10

We enter into derivative financial instruments, including swaps, basis swaps, purchased put and call options and sold call options, to manage the effect of changes in natural gas costs and the price of our nitrogen products. We report the fair value of the derivatives on our balance sheet. If the derivative is not designated as a hedging instrument, changes in fair value are recognized in earnings in the period of change. If the derivative is designated as a cash flow hedge, and to the extent such hedge is determined to be effective, changes in fair value are reported as a component of accumulated other comprehensive income (loss) in the period of change, and subsequently recognized in our statement of operations in the period the offsetting hedged transaction occurs. If an instrument or the hedged item is settled early, we evaluate whether the hedged forecasted transaction is still probable of occurring when determining whether to reclassify any gains or losses immediately in cost of sales or wait until the forecasted transaction occurs.

Until our derivatives settle, we test derivatives ineffectiveness. This includes assessing the correlation of New York Mercantile Exchange (NYMEX) pricing, which is commonly used as an index in natural gas derivatives, to the natural gas pipelines’ pricing at our manufacturing facilities. This assessment requires management judgment to determine the statistically- and industry-appropriate analysis of prior operating relationships between the NYMEX prices and the natural gas pipelines’ prices at our facilities.

To the extent possible, we base our market value calculations on third party data. Due to multiple types of settlement methods available, not all settlement methods for future period trades are available from third party sources. In the event that a derivative is measured for fair value based on a settlement method that is not readily available, we estimate the fair value based on forward pricing information for similar types of settlement methods.

We manage 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.

To manage credit risk, we enter into derivative transactions only with counter-parties who are currently rated as BBB or better or equivalent as recognized by a national rating agency. We will not enter into transactions with a counter-party 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. As of March 31, 2009, we did not have any credit risk related contingent features that would require us to settle the derivative instruments or to post collateral upon the occurrence of a credit event.

We classify a derivative financial instrument as a hedge if all of the following conditions are met:

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

11

We purchase natural gas at market prices to meet production requirements at our manufacturing facility. Natural gas market prices are volatile and we effectively hedge a portion of our natural gas production requirements and inventory through the use of 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, we purchase natural gas for our manufacturing facility 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. Natural gas derivatives are designated as cash flow hedges, provided that the derivatives meet the conditions discussed above. 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 us 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 option contracts require initial premium payments ranging from 2% to 5% of contract value. Basis swap contracts require payments to or from us 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; however, the counterparties require maintenance of cash margin balances generally 10% to 20% of the contract value.

The following summarizes open derivative contracts at March 31, 2009 and 2008:

		March 31,		March 31,
		2009		2008
(in thousands)		Contract		Contract
Transaction Type	Commodity Type	MMBtu		MMBtu

(a) Amounts are disclosed at gross fair value in accordance with SFAS 161 requirements. All of our commodity derivatives are designated as cash flow hedging instruments under SFAS 133. See footnote 1 and 6 of our 2008 Annual Report Form 10-K for additional information on our overall risk management strategies.

Certain derivatives outstanding at March 31, 2009 and 2008, which settled during April 2009 and April 2008, respectively, are included in the position of open natural gas derivatives in the table above. The April 2009 derivatives settled for an approximate $6.0 million loss compared to the April 2008 derivatives which settled for an approximate $4.8 million gain. All open derivatives at March 31, 2009 will settle during the next 12 months.

At March 31, 2009 and 2008, we determined that a portion of certain derivative contracts were ineffective for accounting purposes and, as a result, recorded a $0.6 million charge and a credit of $0.1 million to cost of sales for the three-month periods ending March 31, 2009 and 2008, respectively. At March 31, 2009, we excluded a portion of the loss on certain derivative contracts from the effectiveness assessment and, as a result, reported a $0.6 million charge to cost of sales.

The effective portion of gains and losses on derivative contracts that qualify for hedge treatment are carried as accumulated other comprehensive income (loss) and 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 of 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.

All of our commodity derivatives are designated as cash flow hedging instruments under SFAS 133. See footnote 1 and 6 of our 2008 Annual Report Form 10-K for additional information on our overall risk management strategies. The following table presents the effect of our commodity derivative instruments on the Consolidated Statement of Operations for the three months ended March 31, 2009 and 2008.

Approximately $10.4 million of the net accumulated loss at March 31, 2009 will be reclassified into earnings during the next twelve months as compared to $14.5 million of the net accumulated income at March 31, 2008.

7. Fair Value Measurements

On January 1, 2008, we adopted SFAS No. 157, Fair Value Measurements (SFAS 157), which, among other things, requires enhanced disclosure of assets and liabilities measured and reported at fair value. In February 2008, the FASB issued FASB Staff Position No. 157-2, Effective Date of FASB Statement No. 157, which delayed for one year the applicability of SFAS 157’s fair-value measurements to certain nonfinancial assets and liabilities. We adopted SFAS 157 in 2008, except as it applies to those nonfinancial assets and liabilities affected by the one-year delay. The adoption of SFAS 157 did not have a material impact on our financial statements.

SFAS 157 establishes a hierarchal disclosure framework that prioritizes and ranks the level of market price observability used in measuring assets and liabilities at fair value. Market price observability is impacted by a number of factors, including the type of asset or liability and their characteristics. Assets and liabilities with readily available active quoted prices or for which fair value can be measured from actively quoted prices generally will have a higher degree of market price observability and a lesser degree of judgment used in measuring fair value.

14

The three levels are defined as follows:

• Level 1 — inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets.

• Level 2 — inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.

• Level 3 — inputs to the valuation methodology are observable and significant to the fair value measurement.

We evaluated our assets and liabilities to determine which items should be disclosed according to SFAS 157. We currently measure our derivative contracts on a recurring basis at fair value. The inputs included in the fair value measurement of our derivative contracts use adjusted quoted prices from an active market, which are classified at level 2, as a significant other observable input in the disclosure hierarchy framework as defined by SFAS 157. The Partnership’s gas derivative contracts, which are classified as a level 2 input, are comprised of swaps, basis swaps and options. The valuation techniques for these contracts are observable market data for inputs, including prices quoted on the NYMEX, prices quoted in spot markets and commonly referenced industry publications and prices quoted by market makers. There have been no changes in valuation techniques during the quarter ending March 31, 2009.

The following table summarizes the valuation of our assets and liabilities in accordance with SFAS 157 fair value hierarchy levels as of March 31, 2009:

	Quoted Market		Significant Other			Significant

9.	Revolving Credit Facility
	We have a $50 million revolving credit facility available that expires 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 2.25% at March 31, 2009). Under the credit facility, we 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. Our borrowings under the credit facility are secured by substantially all of our working capital. The agreement also requires us 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, 2009, we had $50 million of borrowing availability and there were no outstanding borrowings or letters of credit under the facility.
10.	Unsolicited Exchange Offer
	On January 15, 2009, CF Industries Holdings, Inc. (CF) presented a letter to Terra’s Board of Directors proposing CF’s acquisition of Terra in an all-stock transaction. Terra’s Board rejected the proposal on the grounds that it was not in the best interest of Terra or its stockholders and substantially undervalued the Company. CF Industries subsequently announced that they remained committed to the proposal, and on February 3, 2009, announced that they would nominate three director candidates to Terra’s Board of Directors and commence an exchange offer for all of Terra’s outstanding common shares.
	On February 23, 2009, CF announced that it had commenced an unsolicited exchange offer to acquire all of the outstanding common shares of Terra at a fixed exchange ratio of 0.4235 CF shares for each Terra common share. In response, Terra’s Board of Directors announced on February 23, 2009 that it would review and consider CF’s exchange offer and make a formal recommendation to shareholders within ten business days, and further advised Terra’s shareholders to take no action pending the review of the proposed exchange offer by Terra’s Board of Directors. On March 3, 2009, Terra’s Board of Directors unanimously concluded that CF’s offer did not present a compelling case to create additional value for the stockholders of either Terra or CF, substantially undervalues Terra on an absolute basis and relative to CF and is not in the best interests of Terra and its stockholders.
	On March 9, 2009, CF sent a letter to Terra’s Board of Directors stating CF would be prepared to enter into a negotiated merger agreement with Terra on the basis of an exchange ratio based on $27.50 for each Terra common share, with an exchange ratio of not less than 0.4129 of a CF common share and not more than 0.4539 of a CF common share. On March 11, 2009, Terra’s Board of Directors unanimously concluded that CF’s proposal continues to run counter to Terra’s strategic objectives, substantially undervalues Terra both absolutely and relative to CF, and would deliver less value to our shareholders than would owning Terra on a stand-alone basis.
	On March 23, 2009, CF sent a letter to Terra’s Board of Directors stating CF would be prepared to enter into a negotiated merger agreement with Terra on the basis of an exchange ratio based on $30.50 for each Terra share, with an exchange ratio of not less than 0.4129 of a CF common share and not more than 0.4539 of a CF common share, the same collar as CF’s proposal of March 9, 2009. On March 24, 2009, Terra’s Board of Directors unanimously concluded that CF’s proposal continues to run counter to Terra’s strategic objectives, substantially undervalues Terra both absolutely and relative to CF, and would deliver less value to our shareholders than it would owning Terra on a stand-alone basis.

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

Overview

You should read the following discussion and analysis in conjunction with our Unaudited Condensed Consolidated Financial Statements and the related Notes thereto contained in Part I, Item 1 of this report. The information contained in this Quarterly Report on Form 10-Q is not a complete description of our business or the risks associated with an investment in our common shares. We urge you to carefully review and consider the various disclosures made by us in this report and in our other reports filed with the SEC, including our Annual Report on Form 10-K for the year ended December 31, 2008 and subsequent reports on Form 8-K, which discuss our business in greater detail.

The section entitled “Risk Factors” contained in Part II, Item 1A of this report, and similar discussions in our other SEC filings, describe some of the important risk factors that may affect our business, financial condition, results of operations and/or liquidity. You should carefully consider those risks, in addition to the other information in this report and in our other filings with the SEC.

Dependence on Terra Industries

We are dependent on Terra Industries Inc. (Terra) in a number of respects. Terra provides all of our management, natural gas purchasing and hedging, selling and administrative services and operates our 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 us. Although Terra is affected by most of the factors that affect us, its higher level of debt could put a greater risk on Terra in the event of adverse business conditions. Our 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 Forms 8-K.

Introduction

In this discussion and analysis, we explain our business in the following areas:

• Business Strategy;

• Recent Business Environment;

• Results of Operations;

• Liquidity and Capital Resources; and

• Various Quantitative and Qualitative Disclosures.

18

Business Strategy

We are a leading producer and marketer of wholesale nitrogen products, serving agricultural and industrial markets. The nitrogen products industry has periods of oversupply during industry downturns that lead to capacity shutdowns at the least cost-effective plants. These shutdowns are followed by supply shortages, which result in higher selling prices and higher industry-wide production rates during industry upturns. The higher selling prices encourage capacity additions until we again start to see an oversupply, and the cycle repeats itself.

To succeed in this business, a producer must have the financial strength to weather industry downturns and the ability to serve its markets cost-effectively during every phase of the cycle. A nitrogen producer will also benefit from having one or more nitrogen products that operate in non-agricultural markets to balance the cyclicality of those markets.

We base our business strategies on these concepts. In practice, this means we:

• Manage our assets to reap the highest returns through the cycle by maintaining our facilities to be safe and reliable, cultivating relationships with natural customers who due to their physical location can receive our product most economically, and closely managing the supply chain to keep storage, transportation and other costs down.

• Develop higher-return product markets, such as that for UAN, our primary nitrogen fertilizer product.

In every case, we invest our capital judiciously to realize a return above the cost of capital over the industry cycle.

Recent Business Environment

The following factors are the key drivers of our profitability: nitrogen products selling prices, as determined primarily by the global nitrogen demand/supply balance, and natural gas costs, particularly in North American markets.

Demand

Despite the global recession the agricultural nitrogen market continues its anticipated growth due to the growing global population. The USDA reported on March 31, 2009 that growers plan to plant 85 million acres of corn in 2009. While this number is down 1% from last year and down 9% from 2007, it would be the third largest acreage since 1949. Factors contributing to the decrease include the decline in agricultural prices, farmers returning to a traditional soybean/corn rotation plan, and the difference in the up-front variable costs to plant soybeans rather than corn, with soybean variable costs of $170/acre as compared to corn variable costs of $390/acre.

The industrial nitrogen market has been affected by the economic downturn and 2009 demand is projected to be down 10-15%. However, this decline will be partially offset by an anticipated increase in demand for ammonia in the environmental market as the effective date of the 2010 emission standards of the 1990 Amendments to the Clean Air Act draw near.

19

Supply

Fall ammonia application was down due to a shortened application window, therefore it is expected that there will be a robust application in the spring. As a result of this decline in fall application, there was build up of inventory and price softening in the fourth quarter of 2008 which led to production curtailments within the industry and a decrease of imports. Overall our plant has run at 86% of capacity in the first quarter of 2009, as compared to 112% in 2008. We expect to operate at full capacity in the second quarter to meet the spring application demand. The supply chain will need to operate efficiently for product to reach the grower during the spring UAN application window. Due to the continued channel struggle between the retailer and grower over pricing, UAN sales volumes have not shipped to the retailer in advance of application as they have in previous years. This could lead to product shortages in areas during the season.

Natural Gas Costs

As a result of the depressed economy, natural gas consumption has declined in the utility and industrial sectors, driving prices below $4 per MMBtu as of March 31, 2009. Natural gas storage is up approximately 20% higher than the five-year average. The following is an average NYMEX forward natural gas price for the succeeding twelve month period noted for the respective dates:

	March 31,		June 30,		September 30,		December 31,		March 31,
(in $ per MMBtu)	2008		2008		2008		2008		2009
	$	10.50	$	13.22	$	7.90	$	6.09	$	4.69

During the first quarter of 2009, natural gas prices decreased 23% from December 31, 2008. Generally, as customers place advance orders we secure the prices for the natural gas required to produce the inventory to satisfy these orders.

RESULTS OF OPERATIONS

Consolidated Results

We reported for the first quarter of 2009 net income of $43.3 million on revenues of $165.3 million, compared with 2008 first quarter net income of $81.6 million on revenues of $174.5 million. The decrease in net income and revenue for the first quarter of 2009 is due to lower UAN sales volumes and lower ammonia sales prices. Net income per common unit for the first quarter of 2009 was $1.49, compared with $3.93 for the first quarter of 2008.

20

The following table shows the results of operations for the three month periods ended March 31, 2009 and 2008:

RESULTS OF OPERATIONS — QUARTER ENDED MARCH 31, 2009 COMPARED WITH QUARTER ENDED MARCH 31, 2008

Our net sales for the first quarter of 2008 were $165.3 million, a decline of $9.2 million or 5% from the first quarter of 2008 net sales of $174.5 million. The decline was primarily due to a 27% decline in UAN sales volumes and a 16% decline in ammonia sales prices, offset by a 176% increase in ammonia sales volumes as compared to the first quarter of 2008. Favorable weather conditions in the Southern plains and the South resulted in an increase in ammonia application in these regions as compared to the first quarter of 2008. This increase can be partially attributed to the catch up of missed fall application in 2008 and the presence of optimal conditions for the application of ammonia in spring 2009. UAN shipments have declined in the first quarter of 2009 as compared to the first quarter of 2008 due to the dynamic between growers and retailers in determining price and high channel inventory levels. First quarter 2008 was highlighted by advanced UAN shipments related to the spring application season.

21

Our gross margin was $48.3 million in the first quarter of 2009 compared to $82.5 million in 2008, and deceased as a percentage of sales to 29.2% from 47.3%. The gross margin percentage reduction reflects the decrease in ammonia sales prices and the decrease in UAN sales volumes and the increase in natural gas costs as a result of losses on derivative instruments. The first quarter natural gas unit costs, net of forward pricing gains and losses, decreased 1.3% from $7.16 per MMBtu in 2008 to $7.07 per MMBtu in 2009. We enter into forward sales commitments by utilizing forward pricing and prepayment programs with customers. We use derivative instruments to hedge a portion of our natural gas requirements. The use of these derivative instruments is designed to hedge exposure to natural gas price fluctuations for production required for forward sales estimates. As a result of forward price contracts, 2009 first quarter natural gas costs were $37.1 million higher than the applicable spot prices, as compared to 2008 first quarter natural gas costs which were $2.2 million lower than the applicable spot prices.

Selling, General and Administrative Costs

Selling, general and administrative costs were $5.3 million in the first quarter of 2009, an increase of $1.8 million from the first quarter of 2008. The increase is primarily due to higher share-based compensation expense resulting from the strengthening of our stock price.

Interest Income

Interest income has decreased in the first quarter of 2009 due to declining interest rates and a reduction of the average investment balance as compared to the first quarter of 2008.

CAPITAL RESOURCES AND LIQUIDITY

Our principal funding needs are to support working capital requirements, make payments for plant turnaround and capital expenditures, and quarterly distributions. Cash and cash equivalent balances at March 31, 2009 were $138.6 million, a decrease of $16.1 million from December 31, 2008.

Our cash receipts are generally received by Terra. Cash receipts, net of cash payments made by Terra, are transferred to us from Terra weekly. Because of this cash collection and distribution arrangement, Terra is a creditor to us.

22

Cash Flows

The following table summarizes our cash flows from operating, investing and financing activities for the three months ended March 31 ($ in thousands):

Total cash provided by (used in)	2009			2008
Operating activities	$	87,367		$	88,610
Investing activities		(10,009	)		(1,958	)
Financing activities		(93,451	)		(84,012	)
Increase (decrease) in cash and cash equivalents	$	(16,093	)	$	2,640

Operating Activities

Net cash provided by operating activities for the first quarter of 2009 represented $47.6 million from operations and $39.8 million from working capital changes. The $47.6 million includes $43.3 million of net income, adjusted for non-cash expenses of $4.3 million of depreciation of plant, property and equipment and amortization of deferred plant turnaround costs.

Investing Activities

Our investing activities used cash of $10.0 million for the first quarter of 2009. This includes $3.6 million of capital and plant turnaround expenditures and a $6.4 million change in our demand deposits with affiliate.

Financing Activities

Our financing activities used cash of $93.5 million related to the distributions paid to our unitholders. The distributions paid are based on the available cash, as defined in our Agreement of Limited Partnership. See Note 3, Agreement of Limited Partnership, of the Notes to the Consolidated Financial Statements, included herein.

Revolving Credit Facility

We have a $50 million revolving credit facility (facility) through January 31, 2012. A portion of this facility is available for swing loans and for the issuance of letters of credit. At March 31, 2009, there were no revolving credit borrowings and there were no outstanding letters of credit. The facility requires us to maintain certain financial ratio covenants relating to minimum earnings, maximum capital expenditures and minimum liquidity. We must also adhere to certain limitations on additional indebtedness, capital expenditures, acquisitions, liens, investments, asset sales, prepayments or subordinated indebtedness, changes in lines of business, restricted payments and transactions with affiliates, among others. Terra and its other domestic subsidiaries have guaranteed our obligations on an unsecured basis. For additional information regarding our facility, see Note 9, Revolving Bank Credit Facility, of the Notes to the Consolidated Financial Statements included in Item 8, Financial Statements and Supplementary Data, of our 2008 Annual Report on Form 10-K.

23

Under the facility, we 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. Our borrowings under the facility are secured by substantially all of our working capital.

In addition, if our aggregate borrowing availability falls below $10 million, we are 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 facility for the preceding four quarter. We are also required to maintain a minimum aggregate unused borrowing availability of $5 million at all times.

Our ability to continue to meet the covenants under the 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 our default such that all outstanding amounts could become immediately due and payable and we would be unable to borrow additional amounts under the facility. Access to adequate bank facilities may be required to fund operating cash needs. Therefore, any default or termination of the facility could have a material adverse effect on our business.

The facility also requires that there be no change of control related to Terra, such that no individual or group (within the meaning of the Securities Exchange Act of 1934, as amended) beneficially owns more than 35% of the outstanding voting shares of Terra. Such a change of control would constitute an event of default under the facility. On February 23, 2009, CF Industries Holdings, Inc. (CF) commenced an exchange offer to acquire all of the outstanding Terra common stock. Such a business combination, if consummated, would constitute a change of control under the facility. See Note 10, Unsolicited Exchange Offer by CF Industries Holdings, Inc., to the Notes for the Consolidated Financial Statements on this Form 10-Q for additional information with respect to CF’s unsolicited proposal.

We expect the facility to be adequate to meet our operating needs.

Debt

The General Partner is an indirect, wholly-owned subsidiary of Terra. Under the General Partner’s governing documents, neither we nor the General Partner may make any bankruptcy filing (or take similar action) without the approval of the General Partners’ independent directors.

Partnership Distributions

We make quarterly distributions to our partners based on “Available Cash” for the quarter, as defined in our 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. We paid distributions of $93.5 million and $84.0 million for the quarters ended March 31, 2009 and 2008, respectively.

24

We receive 99% of the Available Cash from Terra Nitrogen, Limited Partnership (“the Operating Partnership”) and 1% is distributed to its general partner, (who is also our General Partner). Cash distributions from the Operating Partnership generally represent our Available Cash from operations. Our cash distributions are made 99.975% to Common Unitholders and 0.025% to our General Partner, except when cumulative distributions of Available Cash exceed specified target levels above the Minimum Quarterly Distributions (“MQD”) of $0.605 per unit. Under such circumstances, our General Partner is entitled, as an incentive, to larger percentage interests. Pursuant to our Agreement of Limited Partnership, income allocable to the Limited Partner and General Partner is based upon the distributions of Available Cash for the year. Therefore, earnings per unit reflect an annualized allocation rate.

On April 21, 2009, we announced a $2.10 cash distribution per common limited partnership unit payable on May 27, 2009, to holders of record as of May 5, 2009. We have exceeded the cumulative MQD amounts and will distribute Available Cash as summarized in the following table:

	Income and Distribution Allocation

The General Partner is required to remit the majority of cash distributions it receives from the Partnership, in excess of its 1% Partnership equity interest, to an affiliated company.

General Partner Option to Effect Mandatory Redemption of Partnership Units

At March 31, 2009, the General Partner and its affiliates owned 75.3% of our outstanding units. When not more than 25% of the issued and outstanding units are held by non-affiliates of the General Partner, as was the case at March 31, 2009, we, at the General Partner’s sole discretion, may call, or assign to the General Partner or its affiliates, our right to acquire all such outstanding units held by non-affiliated persons. If the General Partner elects to acquire all outstanding units, we are required to give at least 30 but not more than 60 days’ notice of our 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.

Our cash receipts are generally received by Terra on our behalf. Cash receipts, net of cash payments made by Terra, are transferred to us from Terra on a weekly basis. As a result of this cash collection and distribution arrangement, Terra is a creditor to us.

There were no material changes outside the ordinary course of business to the Partnerhip’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, 2008.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our operations are significantly affected by the price of natural gas. We employ derivative commodity instruments related to a portion of our natural gas requirements (primarily 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 we manage specific risk exposures, refer to our 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 our 2008 Form 10-K. There were no material changes in our use of financial instruments during the quarter ended March 31, 2009.

Natural gas is the principal raw material used to manufacture nitrogen. Natural gas prices are volatile and we mitigate some of this volatility through the use of derivative commodity instruments. Our current policy is to hedge natural gas provided that such arrangements would not result in costs greater than expected selling prices for our finished products. Estimated North American natural gas requirements for 2009 are approximately 38 billion cubic feet (BCF). We have hedged 29% of our expected North American requirements for the next twelve months. The fair value of these instruments is estimated based, in part, on quoted market prices from brokers, realized gains or losses and or computations. These instruments and other natural gas positions fixed natural gas prices at $11.7 million (includes $10.4 million related to accumulated other comprehensive loss) more than published prices for March 31, 2009 forward markets.

The General Partner’s ability to manage our exposure to commodity price risk in the purchase of natural gas through the use of financial derivatives may be affected by limitations imposed by our bank agreement covenants.

ITEM 4. CONTROLS AND PROCEDURES

Our 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 our disclosure controls and procedures are effective to ensure that information required to be disclosed in the reports that we file or submit under the Securities Exchange Act of 1934 are 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 our internal control over financial reporting that occurred during the most recent quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
