NORTHERN TECHNOLOGIES INTERNATIONAL CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1. INTERIM FINANCIAL INFORMATION

In the opinion of management, the accompanying unaudited consolidated financial statements contain all necessary adjustments, which are of a normal recurring nature, and present fairly the consolidated financial position of Northern Technologies International Corporation and its subsidiaries (the “Company”) as of February 28, 2011 and the results of their operations for the three and six months ended February 28, 2011 and February 28, 2010 and their cash flows for the six months ended February 28, 2011 and February 28, 2010, in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”).

Certain amounts reported in the consolidated financial statements for the previous reporting periods have been reclassified to conform to the current period presentation. These reclassifications did not have a material impact on the Company’s previously reported consolidated balance sheets or statements of cash flows. The Company has reclassified various line items in the consolidated statements of operations to better provide the results of its joint ventures, as well as its North American operations. These reclassifications changed the Company’s operating income, but did not impact its net income or net income per common share.

These consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes contained in the Company’s annual report on Form 10-K for the fiscal year ended August 31, 2010. These consolidated financial statements also should be read in conjunction with the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” section appearing in this report.

Operating results for the three and six months ended February 28, 2011 are not necessarily indicative of the results that may be expected for the full fiscal year ending August 31, 2011.

The Company evaluates events occurring after the date of the consolidated financial statements requiring recording or disclosure in the financial statements.

2. CONSOLIDATION OF ZERUST BRAZIL

Beginning in the fourth quarter of fiscal 2010, the Company consolidated the results of Zerust Prevenção de Corrosão S.A., the Company’s subsidiary in Brazil (“Zerust Brazil”). The Company holds 85% of the equity and 85% of the voting rights of Zerust Brazil. Prior to the fourth quarter of fiscal 2010 and as of February 28, 2010, the Company accounted for its Zerust Brazil investment under the equity method. The Company owned only 50%, which it considered to be less than a majority, of the equity and voting rights of Zerust Brazil prior to September 2006. The Company acquired an additional 35% ownership interest in Zerust Brazil in September 2006 and held 85% of the equity and voting rights thereafter. Prior to the fourth quarter of fiscal 2010, the Company held the additional 35% ownership interest in Zerust Brazil with the intent of finding an acquiring party, believing its majority control of Zerust Brazil would be temporary and determined not to consolidate Zerust Brazil because the impact on the Company’s consolidated financial statements was immaterial. During the fourth quarter of fiscal 2010, the Company stopped pursuing a buyer of the 35% ownership interest and decided to consolidate the financial results of Zerust Brazil as of and for the fiscal year ended August 31, 2010. The Company believes that the impact of not consolidating Zerust Brazil on the Company’s consolidated financial statements for periods prior to the fourth quarter of fiscal 2010 was immaterial to the Company’s consolidated financial statements.

The following is a summary of certain line items of the Company’s consolidated statements of operations for the three months ended February 28, 2010 as reported and on a pro forma basis, assuming the consolidation of Zerust Brazil on the Company’s consolidated financial statements as of the beginning of such period:

7. NOTE PAYABLE AND LINE OF CREDIT

In connection with the purchase of its corporate headquarters, in September 2006, Northern Technologies Holding Company, LLC (“NTI LLC”) obtained a term loan from PNC Bank, National Association (“PNC Bank”) with a principal amount of $1,275,000 that was to mature on May 1, 2011. On January 10, 2011, NTI LLC refinanced its term loan in the then principal amount of approximately $1,141,788. The term loan matures on January 10, 2016, bears interest at an annual rate based on the daily LIBOR rate plus 2.15% and is payable in 59 consecutive monthly installments equal to approximately $6,343 (inclusive of principal but exclusive of interest) commencing in February 2011. The term loan is secured by a first lien on the real estate and building owned by NTI LLC and all of the assets of the Company and is guaranteed by the Company.

As of February 28, 2011, the Company had a revolving line of credit with PNC Bank of $3,000,000 with no amounts outstanding as of such date. As of August 31, 2010, the Company had a demand line of credit of $2,300,000 with PNC Bank with no amounts outstanding as of such date. Any advances made under the revolving line of credit are due and payable on January 10, 2012. At the option of the Company, outstanding advances under the line of credit bear interest at either (a) an annual rate based on LIBOR plus 2.15% for the applicable LIBOR interest period selected by the Company or (b) at the rate publicly announced by PNC Bank from time to time as its

prime rate. Interest is payable in arrears (a) for the portion of advances bearing interest under the prime rate on the last day of each month during the term thereof and (b) for the portion of advances bearing interest under the LIBOR option on the last day of the respective LIBOR interest period selected for such advance. Any unpaid interest is payable on the maturity date. Outstanding amounts under the prior demand line of credit bore interest at an annual rate based on LIBOR plus 2.25%. As of February 28, 2011, the interest rate was 2.35% and the weighted average rate was 2.39% for the six months ended February 28, 2011. As of February 28, 2010, the interest rate was 3.08% and the weighted average rate was 3.36% for the six months ended February 28, 2010.

Both the term loan and the line of credit are governed under two separate loan agreements (collectively, the “Loan Agreements”). The Loan Agreements contain standard covenants, including affirmative financial covenants, such as the maintenance of a minimum fixed charge coverage ratio, and negative covenants, which, among other things, limit the incurrence of additional indebtedness, loans and equity investments, disposition of assets, mergers and consolidations and other matters customarily restricted in such agreements. Under the Loan Agreements, the Company is subject to a minimum fixed charge coverage ratio of 1.10:1.00.

10. NET INCOME PER COMMON SHARE

Basic net income per common share is computed by dividing net income by the weighted average number of common shares outstanding. Diluted net income per share assumes the exercise of stock options using the treasury stock method, if dilutive.

No options to purchase shares of common stock were excluded from the computation of common share equivalents for both the three and six months ended February 28, 2011. Options to purchase 64,140 shares of common stock were excluded from the computation of common share equivalents for both the three and six months ended February 28, 2010, as stock option exercise prices were greater than the market price of a share of common stock.

11. STOCK-BASED COMPENSATION

The Company has several stock-based compensation plans under which stock options and other stock-based awards have been granted, including the Northern Technologies International Corporation Amended and Restated 2007 Stock Incentive Plan (the “2007 Plan”), the Northern Technologies International Corporation 2000 Stock Incentive Plan (the “2000 Plan”) and the Northern Technologies International Corporation Employee Stock Purchase Plan (the “ESPP”). The Compensation Committee of the Board of Directors and the Board of Directors administers all of these plans.

The 2007 Plan replaced the 2000 Plan, which was terminated with respect to future grants, but continues to govern grants outstanding under such plan. The 2007 Plan provides for the grant of incentive stock options, non-statutory stock options, stock appreciation rights, restricted stock, stock unit awards, performance awards and stock bonuses to eligible recipients to enable the Company and its subsidiaries to attract and retain qualified individuals through opportunities for equity participation in the Company, and to reward those individuals who contribute to the achievement of the Company’s economic objectives. Subject to adjustment as provided in the 2007 Plan, up to a maximum of 800,000 shares of the Company’s common stock plus the number of shares subject to awards outstanding under the prior 2000 Plan as of January 20, 2011 but only to the extent that such outstanding awards are forfeited, expire or otherwise terminate without the issuance of such shares, are available for issuance under the 2007 Plan. Options granted under the 2007 Plan generally have a term of five years and become exercisable over a three- or four-year period beginning on the one-year anniversary of the date of grant. Options are granted at per share exercise prices equal to the market value of the Company’s common stock on the date of grant. To date, only stock options and stock bonuses have been granted under the 2007 Plan.

The maximum number of shares of common stock of the Company available for issuance under the ESPP is 100,000 shares, subject to adjustment as provided in the ESPP. The ESPP provides for six-month offering periods beginning on September 1 and March 1 of each year. The purchase price of the shares is 90% of the lower of the fair market value of common stock at the beginning or end of the offering period. This discount may not exceed the maximum discount rate permitted for plans of this type under Section 423 of the Internal Revenue Code of 1986, as amended. The ESPP is compensatory for financial reporting purposes.

The Company granted options to purchase 30,000 and 128,333 shares of its common stock during the six months ended February 28, 2011 and 2010, respectively. The fair value of option grants is determined at date of grant, using the Black-Scholes option pricing model with the assumptions listed below. Based on these valuations, the Company recognized compensation expense of $109,880 and $94,210 during the six months ended February 28, 2011 and 2010, respectively, related to the options that vested during such time period. The stock-based expense recorded reduced after-tax net income per share by $0.02 for each of the six months ended February 28, 2011 and 2010. As of February 28, 2011, the total compensation cost for non-vested options not yet recognized in the Company’s consolidated statements of operations was $237,875 net of estimated forfeitures. Additional stock-based compensation expense of $80,457 is expected through the remainder of fiscal year 2011, and expense of $129,342 and $28,076 is expected to be recognized during fiscal 2012 and fiscal 2013, respectively. Future option grants will impact the compensation expense recognized.

The Company currently estimates a ten percent forfeiture rate for stock options and continually reviews this estimate for future periods.

The fair value of each option grant is estimated on the grant date using the Black-Scholes option-pricing model with the following assumptions and results for the grants:

	February 28,
	2011	2010
Dividend yield	0.00%	0.00%
Expected volatility	49.2%	48.3%
Expected life of option	5 years	5 years
Average risk-free interest rate	1.31%	2.34%

The weighted average per share fair value of options granted during the six months ended February 28, 2011 and 2010 was $3.60 and $2.99, respectively. The weighted average remaining contractual life of the options outstanding as of February 28, 2011 and 2010 was 3.20 years and 3.01 years, respectively.

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

This Management’s Discussion and Analysis provides material historical and prospective disclosures intended to enable investors and other users to assess NTIC’s financial condition and results of operations. Statements that are not historical are forward-looking and involve risks and uncertainties discussed under the heading “Part I. Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Forward-Looking Statements.” The following discussion of the results of the operations and financial condition of NTIC should be read in conjunction with NTIC’s consolidated financial statements and the related notes thereto included under the heading “Part I. Item 1. Financial Statements.”

Business Overview

NTIC develops and markets proprietary environmentally beneficial products and technical services in over 55 countries either directly or via a network of joint ventures and independent distributors. NTIC’s primary business is corrosion prevention. From this base, NTIC has expanded into three new business areas that have started recently to generate revenue (1) corrosion prevention technologies specifically designed for the oil and gas industry, which NTIC sells both directly as well as through joint ventures and independent agents; (2) a proprietary portfolio of bio-plastic compounds and finished products marketed under the Natur-Tec® brand, which NTIC sells directly as well as through distributors and independent agents; and (3) technology and equipment that converts waste plastic into diesel, gasoline and heavy fractions, which is exclusively licensed and sold in North America and Asia through NTIC’s joint venture Polymer Energy, LLC.

NTIC has been selling its proprietary ZERUST® brand rust and corrosion inhibiting products and services to the automotive, electronics, electrical, mechanical, military and retail consumer markets for over 35 years. NTIC also offers worldwide on-site technical consulting for rust and corrosion prevention issues. In North America, NTIC markets its technical services and products principally to industrial users by a direct sales force as well as a network of independent distributors and agents. NTIC’s technical service consultants work directly with the end users of NTIC’s products to analyze their specific needs and develop systems to meet their technical requirements.

NTIC has developed proprietary corrosion inhibiting technologies for use in the mitigation of corrosion on capital assets used in the petroleum and chemical process industries and is initially targeting the sale of these new ZERUST® products to the oil and gas industry sector. During fiscal 2009, NTIC announced the signing of a multi-year contract between NTIC’s Brazilian subsidiary (Zerust Prevenção de Corrosão S.A.) and Petroleo Brasileiro S.A. (Petrobras) to install and service proprietary corrosion protection technologies on the roofs of an initial set of aboveground oil storage tanks at the Petrobras REDUC refinery in Rio de Janeiro, Brazil. Also during fiscal 2009, NTIC signed multiple joint research and development contracts with Petrobras’s research and development group at the Leopoldo Américo Miguez de Mello Research & Development Center (CENPES) pursuant to which the parties will undertake a 20-month Petrobras funded effort to explore, understand and resolve bottom plate corrosion issues in aboveground storage tanks. A second 12-month Petrobras sponsored project has also started aimed at field trials of certain pipeline protection technologies. All of these projects continued during fiscal 2010 and the first six months of fiscal 2011. NTIC also is pursuing opportunities to market its ZERUST® corrosion prevention technology to other potential customers in the oil and gas industry across several countries through NTIC’s joint venture partners and other strategic partners. During fiscal 2010, NTIC entered into agreements with Iromad VZ, LLC and GF Consulting Services LLC to provide sales and marketing services for NTIC’s oil and gas industry specific corrosion prevention technologies with a particular focus on the markets in the United States, Venezuela, Mexico and Spain. NTIC believes the sale of its ZERUST® products to customers in the oil and gas industry will involve a long sales cycle, likely including a one- to two-year trial period with each customer and a slow integration process thereafter.

In addition to ZERUST® products and services, NTIC develops and markets a portfolio of bio-based and/or biodegradable (compostable) polymer resin compounds and finished products under the Natur-Tec® brand. The

Natur-Tec® bioplastics portfolio includes flexible film, foam, rigid injection molded materials and engineered plastics. Natur-Tec® biodegradable and compostable finished products include shopping and grocery bags, lawn and leaf bags, can liners, pet waste collection bags, cutlery, packaging foam and coated paper products and are engineered to be fully biodegradable in a composting environment. During fiscal 2010 and the first six months of fiscal 2011, NTIC focused on adding additional distributors and generating initial sales with these distributors.

NTIC’s Polymer Energy LLC joint venture develops and promotes a system that uses catalytic pyrolysis to convert waste plastic (primarily polyolefins) into hydrocarbons (primarily a mix of diesels, gasoline and heavy fractions) resulting in an economically viable and environmentally responsible alternative to current methods of recycling and disposal of waste plastic. Each unit can process up to ten tons of waste plastic per day, and the modular design allows for easily scalable capacity. The crude output is high-grade and can be further processed in a refinery or used as an input for co-generation of electricity. During fiscal 2010 and the first six months of fiscal 2011, NTIC’s Polymer Energy LLC joint venture focused on making design improvements to the Polymer Energy™ equipment and generating initial interest from potential customers in India, Thailand and Indonesia.

NTIC’s Joint Venture Network

NTIC participates in 26 active joint venture arrangements in North America, South America, Europe, Asia and the Middle East. Each of these joint ventures generally manufactures and markets finished products in the geographic territory to which it is assigned. While currently most of NTIC’s joint ventures exclusively sell rust and corrosion inhibiting packaging and products to industrial customers, NTIC also has joint ventures that manufacture, market and sell corrosion prevention solutions for the oil and gas industry and Polymer Energy™ equipment that converts waste plastic into diesel, gasoline and heavy fractions. NTIC historically has funded its joint venture investments with cash generated from operations.

NTIC’s receipt of funds from its joint ventures is dependent upon fees for services that NTIC provides to its joint ventures based primarily on the revenues of the joint ventures and NTIC’s receipt of dividend distributions from the joint ventures. NTIC receives fees for services provided to its joint ventures based primarily on the net sales of the individual joint ventures. The fees for services provided to joint ventures are determined based on either a flat fee or a percentage of sales depending on local laws and tax regulations. With respect to its German joint venture, NTIC recognizes an agreed upon quarterly fee for such services. With respect to its ASEAN joint venture holding company, NTIC does not receive a fee for such services, but rather receives a bi-annual dividend based on available cash. NTIC recognizes equity income from its joint ventures based on the overall profitability of the entity. The profits of NTIC’s joint ventures are shared by the respective joint venture owners in accordance with their respective ownership percentages. NTIC typically owns only 50% or less of its joint venture entities and thus does not control the decisions of these entities regarding whether to pay dividends and, if paid, how much they should be in a given year. The payment of a dividend by an entity is determined by a joint vote of the owners and is not at the sole discretion of NTIC.

NTIC does not consolidate the results of its joint ventures, other than commencing in the fourth quarter of 2010, Zerust Prevenção de Corrosão S.A., NTIC’s subsidiary in Brazil (“Zerust Brazil”). NTIC holds 85% of the equity and 85% of the voting rights of Zerust Brazil. Prior to fiscal 2010 NTIC accounted for its Zerust Brazil investment under the equity method. NTIC owned only 50%, which it considered to be less than a majority, of the equity and voting rights of Zerust Brazil prior to September 2006. NTIC acquired an additional 35% ownership interest in Zerust Brazil in September 2006 and held 85% of the equity and voting rights thereafter. Prior to the fourth quarter of fiscal 2010, NTIC held the additional 35% ownership interest in Zerust Brazil with the intent of finding an acquiring party, believing its majority control of Zerust Brazil would be temporary and determined not to consolidate Zerust Brazil because the impact on NTIC’s consolidated financial statements was immaterial. During the fourth quarter of fiscal 2010, NTIC stopped pursuing a buyer of the 35% ownership interest and decided to consolidate the financial results of Zerust Brazil as of and for the fiscal year ended August 31, 2010. NTIC believes that the impact of not consolidating Zerust Brazil on NTIC’s consolidated financial statements for periods prior to the fourth quarter of fiscal 2010 was immaterial to NTIC’s consolidated financial statements.

NTIC has not consolidated the Polymer Energy LLC joint venture in NTIC’s consolidated financial statements for the six months ended February 28, 2011 or 2010 or any prior period since Polymer Energy LLC has had limited activity since its inception in 2003 and NTIC believes that the impact of not consolidating this entity on NTIC’s consolidated financial statement has been immaterial. Prior to fiscal 2010, Polymer Energy LLC did not have any financial activity including assets, liabilities, capital contributions, revenues or expenses. During fiscal 2010, the only financial activity of Polymer Energy LLC was the receipt of license fees which were distributed to its owners in proportion to their respective ownership percentages. Since NTIC owns a 62.5% ownership interest in Polymer Energy LLC, NTIC received and recorded a portion of these fees for services provided to joint ventures in its fiscal 2010 consolidated financial statements. No license fees were received by Polymer Energy LLC and no other financial activity took place during the six months ended February 28, 2011. Accordingly, during the six months ended February 28, 2011, NTIC received and recorded no fees for services provided to joint ventures in its consolidated financial statements attributable to its ownership interest in Polymer Energy LLC.

NTIC considers its German joint venture and ASEAN joint venture holding company to be individually significant to NTIC’s consolidated assets and income; and therefore, provides certain additional information regarding these joint ventures in the notes to NTIC’s consolidated financial statements and in this section of this report.

Financial Overview

NTIC’s management, including its chief executive officer who is NTIC’s chief operating decision maker, reports and manages NTIC’s operations in two reportable business segments based on products sold, customer base and distribution center: ZERUST® products and services and Natur-Tec® products.

NTIC’s consolidated net sales increased 66.1% and 58.9% during the three and six months ended February 28, 2011, respectively, compared to the three and six months ended February 28, 2010. These increases were primarily a result of increased sales of ZERUST® rust and corrosion inhibiting packaging products and services and sales to NTIC’s joint ventures and the consolidation of Zerust Brazil on NTIC’s consolidated financial statements. During the three and six months ended February 28, 2011, 95.8% and 95.2% of NTIC’s consolidated net sales, respectively, were derived from sales of ZERUST® products and services, which increased 64.3% and 56.1% to $4,576,313 and 8,451,741 during the three and six months ended February 28, 2011, respectively, compared to $2,785,454 and $5,413,009 during the three and six months ended February 28, 2010, respectively, due to increased demand primarily as a result of the economic recovery of the domestic manufacturing sector, the addition of new customers and the consolidation of Zerust Brazil, partially offset by decreased pricing due to increased competition. During the three and six months ended February 28, 2011, 4.2% and 4.8%, respectively, of NTIC’s consolidated net sales were derived from sales of Natur-Tec® products compared to 3.2% and 3.1% during the three and six months ended February 28, 2010, respectively. Net sales of Natur-Tec® products increased 166.0% and 142.9% during the three and six months ended February 28, 2011, respectively, compared to the three and six months ended February 28, 2010. These increases were primarily due to the addition of new Natur-Tec® distributors on the west coast of the United States.

Cost of goods sold as a percentage of net sales decreased slightly to 62.9% and 64.2% for the three and six months ended February 28, 2011, respectively, compared to 64.0% and 64.4% for the three and six months ended February 28, 2010, respectively, primarily as a result of increased net sales, partially offset by slightly reduced margins resulting from a slight increase in raw material prices.

NTIC’s equity in income of joint ventures increased 63.3% and 102.1% during the three and six months ended February 28, 2011, respectively. Equity in income of joint ventures was $1,129,659 and $2,824,790 during the three and six months ended February 28, 2011, respectively, compared to $691,687 and $1,397,586 during the three and six months ended February 28, 2010, respectively. NTIC recognized a 22.0% and 24.0% increase in fees for services provided to joint ventures during the three and six months ended February 28, 2011, respectively, compared to the three and six months ended February 28, 2010. Both of these increases were primarily a result of a 34.0% increase in total net sales of NTIC’s joint ventures during the six months ended February 28, 2011 compared to the six months ended February 28, 2010. This increase in total net sales of NTIC’s joint ventures was primarily a result of the economic recovery, to some extent, of the international manufacturing sector that the NTIC joint venture network serves.

NTIC’s total operating expenses increased 33.9% during the six months ended February 28, 2011 compared to the six months ended February 28, 2010 primarily as a result of the consolidation of the selling and general and administrative expenses of Zerust Brazil on NTIC’s consolidated financial statements of $450,828, the return of wages for all employees to pre-recession levels and fiscal 2011 raises, the hiring of 15 employees since November 30, 2009 and the increase in accrual of the management bonus of $499,000.

NTIC expenses all costs related to product research and development as incurred. NTIC incurred $2,100,626 and $1,565,698 of expense during the six months ended February 28, 2011 and 2010, respectively, in connection with its research and development activities. These costs related to product research and development are the net of reimbursement of multiple research and development contracts of $212,992 and $286,479 for the six months ended February 28, 2011 and 2010, respectively. NTIC anticipates that it will spend between $3,500,000 and $4,000,000 in total during fiscal 2011 on research and development activities related to its core and new technologies. These

amounts represent net amounts after being reduced by reimbursements related to the awarding of multiple research and development contracts.

Net income attributable to NTIC increased 173.8%, to $949,039, or $0.22 per diluted common share, for the three months ended February 28, 2011 compared to $346,641, or $0.08 per diluted common share, for the three months ended February 28, 2010. Net income attributable to NTIC increased 136.3%, to $1,848,820, or $0.42 per diluted common share, for the six months ended February 28, 2011 compared to $782,346, or $0.19 per diluted common share, for the six months ended February 28, 2010. These increases were primarily the result of increased income from NTIC’s corporate joint ventures and holding companies and gross profit, partially offset by an increase in operating expenses. We anticipate that our quarterly net income will remain subject to significant volatility primarily due to the financial performance of our joint ventures and sales of our ZERUST® products and services into the oil and gas industry and Natur-Tec® bioplastics products, which sales fluctuate more on a quarterly basis than our traditional ZERUST® business.

NTIC’s working capital was $9,267,637 at February 28, 2011, including $1,864,215 in cash and cash equivalents compared to $5,918,923 at August 31, 2010, including $1,776,162 in cash and cash equivalents. On January 10, 2011, NTIC refinanced its $1,275,000 original principal amount term loan and increased its line of credit with PNC Bank, National Association (“PNC Bank”) to $3,000,000.

Results of Operations

NTIC does not consolidate the results of its joint ventures. NTIC considers its German joint venture and ASEAN joint venture holding company to be individually significant to NTIC’s consolidated assets and income; and therefore, provides certain additional information regarding these joint ventures in the notes to NTIC’s consolidated financial statements and in this section of this report.

The following table sets forth NTIC’s results of operations for the three months ended February 28, 2011 and February 28, 2010.

Net Sales. NTIC’s consolidated net sales increased 66.1% and 58.9% to $4,778,118 and $8,876,559, respectively during the three and six months ended February 28, 2011 compared to the three and six months ended February 28, 2010. NTIC’s consolidated net sales to unaffiliated customers excluding NTIC’s joint ventures increased 60.6% and 59.4% to $4,093,107 and $7,539,410, respectively, during the three and six months ended February 28, 2011 compared to the same respective prior year periods. These increases were primarily a result of increased sales of ZERUST® rust and corrosion inhibiting packaging products and services and sales to NTIC’s joint ventures and the consolidation of Zerust Brazil on NTIC’s consolidated financial statements as discussed in more detail below. Net sales to joint ventures increased 108.5% and 55.9% to $685,011 and $1,337,149 during the three and six months ended February 28, 2011, respectively, compared to the same respective prior year periods. These increases were due to increases in demand primarily as a result of the economic recovery of the international manufacturing sector, partially offset by decreased pricing due to increased competition.

The following table sets forth NTIC’s net sales by product category for the three and six months ended February 28, 2011 and 2010 by segment:

	Three Months Ended				Six Months Ended
	February 28, 2011		February 28, 2010		February 28, 2011		February 28, 2010
ZERUST® sales	$	4,576,313	$	2,785,452	$	8,451,741	$	5,413,009
Natur-Tec™ sales		201,805		91,026		424,818		174,871
Total North American net sales	$	4,778,118	$	2,876,478	$	8,876,559	$	5,587,880

During the three and six months ended February 28, 2011, 95.8% and 95.2% of NTIC’s consolidated net sales, respectively, were derived from sales of ZERUST® products and services, which increased 64.3% and 56.1% to $4,576,313 and $8,451,741 during the three and six months ended February 28, 2011, respectively, compared to $2,785,452 and $5,413,009 during the three and six months ended February 28, 2010, respectively, due to increased demand primarily as a result of the economic recovery of the domestic manufacturing sector, the addition of new customers and the consolidation of Zerust Brazil, partially offset by decreased pricing due to increased competition. Overall demand for ZERUST® products and services depends heavily on the overall health of the markets in which NTIC sells its products, including in particular the automotive market. NTIC has focused its sales efforts of ZERUST® products and services by strategically targeting customers with specific corrosion issues in new market areas, including the oil and gas industry and other industrial sectors that offer sizable growth opportunities. NTIC’s consolidated net sales during the three and six months ended February 28, 2011 included $1,034,483 and $1,551,623, respectively, of sales made by Zerust Brazil, and of those sales, $600,200 and $627,022, respectively, in sales were made to the oil and gas industry sector in Brazil. As previously disclosed, during the fourth quarter of fiscal 2010, Zerust Brazil received purchase orders for Flange Savers representing an aggregate of $1.4 million. Of those orders, Zerust Brazil recognized sales of $518,000 during the fourth quarter of fiscal 2010, $26,822 during the first quarter of fiscal 2011 and $600,200 during the second quarter of fiscal 2011. NTIC anticipates sales to Petrobras for the remaining $254,978 of these orders during fiscal 2011 as Petrobras rolls this product out to more of its platforms. NTIC also anticipates that its sales of ZERUST® products and services into the oil and gas industry will remain subject to significant volatility from quarter to quarter as sales are converted and purchase orders are filled.

Net sales of Natur-Tec® products increased 121.7% and 142.9% to $201,805 and $424,818 during the three and six months ended February 28, 2011, respectively, compared to the three and six months ended February 28, 2010. These increases were primarily due to the addition of new Natur-Tec® distributors on the West Coast of the United States. NTIC anticipates additional revenue in future periods from anticipated sales of film-grade resin to customers in both the North American and European markets, primarily to meet anticipated demand for biodegradable plastic bags that comply with various regulations. Additionally, NTIC is continuing to strengthen and expand its west coast distribution network in California, while expanding its industrial distribution reach to geographical “green” hotspots such as Oregon, Washington, Minnesota and New England. Additionally, NTIC is targeting key national and regional retailers utilizing independent sales agents. Demand for the Natur-Tec® products depends primarily on market acceptance of the products and the extent of NTIC’s distribution network, which as of February 28, 2011 consisted of approximately 15 distributors and independent manufacturer’s sales representatives.

Cost of Goods Sold. Cost of goods sold increased 63.3% and 59.8% for the three and six months ended February 28, 2011, respectively, compared to the three and six months ended February 28, 2010 primarily as a result of increased net sales as described above. Cost of goods sold as a percentage of net sales decreased slightly to 62.9% and 64.2% for the three and six months ended February 28, 2011, respectively, compared to 64.0% and 64.4% for the three and six months ended February 28, 2010, respectively, primarily as a result of increased net sales, partially offset by slightly reduced margins resulting from a slight increase in raw material prices.

Equity in Income of Joint Ventures. NTIC had equity in income of joint ventures of $1,129,659 and $2,824,790 during the three and six months ended February 28, 2011, respectively, compared to equity in income of joint ventures of $691,687 and $1,397,586 during the three and six months ended February 28, 2010, respectively. The increase in equity in income was due to increased profitability of NTIC’s joint ventures primarily resulting from increased sales. Of the total equity in income of joint ventures, NTIC had equity in income of joint ventures of $1,547,773 attributable to its joint venture in Germany during the six months ended February 28, 2011 compared to $731,452 attributable to its joint venture in Germany during the six months ended February 28, 2010. Of the total equity in income of joint ventures, NTIC had equity in income of joint ventures of $558,260 attributable to its ASEAN joint venture holding company during the six months ended February 28, 2011 compared to $419,324 attributable to its ASEAN joint venture holding company during the six months ended February 28, 2010. NTIC had equity in income of all other joint ventures of $718,757 during the six months ended February 28, 2011 compared to $246,810 during the six months ended February 28, 2011.

Fees for Services Provided to Joint Ventures. NTIC recognized fee income for services provided to joint ventures of $1,402,149 and $2,853,929 during the three and six months ended February 28, 2011, respectively, compared to $1,149,338 and $2,301,268 during the three and six months ended February 28, 2010, respectively, representing an increase of 22.0% and 24.0%, respectively. These increases in fees for services provided to joint ventures were due primarily to increases in net sales of NTIC’s joint ventures, which increased to $53,405,322 in the six months ended February 28, 2011 compared to $39,854,071 in the six months ended February 28, 2010, representing an increase of 34.0%. Sales of NTIC’s joint ventures, other than Zerust Brazil, are not included in NTIC’s product sales and are not combined with NTIC’s sales in NTIC’s consolidated financial statements or in any description of NTIC’s sales.

Of the total fee income for services provided to its joint ventures, fees of $521,753 were attributable to NTIC’s joint venture in Germany during the six months ended February 28, 2011 compared to $521,098 attributable to its joint venture in Germany during the six months ended February 28, 2010. This slight increase was the result of foreign currency exchange rate fluctuations. NTIC does not receive fees attributable to its ASEAN joint venture holding company. NTIC receives dividend payments based on fees paid from the joint ventures that comprise the ASEAN investments.

NTIC sponsors a worldwide joint venture conference approximately every three to four years in which all of NTIC’s joint ventures and subsidiaries are invited to participate. NTIC defers a portion of its fees for services provided to joint ventures in each accounting period leading up to the next conference, reflecting that NTIC has not

fully earned the payments received during that period. The next joint venture conference is scheduled to be held in the summer of 2012. There was no additional deferred income recorded within other accrued liabilities during the six months ended February 28, 2011 related to this future conference since $288,000 had been accrued over the past three fiscal years, which represents the amount that NTIC expects to spend every three years to hold the conference. This amount is based on the historical experience of NTIC, current conditions and the intentions of NTIC’s management. NTIC does not anticipate deferring any additional fees for services provided to joint ventures until after the next conference. The costs associated with these joint venture conferences are offset against the deferral as incurred, generally in the period in which the conference is held and immediately before.

Selling Expenses. NTIC’s selling expenses increased 56.8% for the three months ended February 28, 2011 compared to the same period in fiscal 2010 due to increases in (i) compensation and employee benefits of $150,000; (ii) lab testing related expenses of $10,000; (iii) commission expenses of $31,000; (iv) travel and related expenses of $43,000; (v) consulting expenses of $28,000 and (vi) selling expenses incurred at Zerust Brazil of $123,000. NTIC’s selling expenses increased 62.1% for the six months ended February 28, 2011 compared to the same period in fiscal 2010 due to increases in (i) compensation and employee benefits of $190,000; (ii) lab testing related expenses of $15,000; (iii) commission expenses of $51,000; (iv) travel and related expenses of $42,000; (v) consulting expenses of $28,000 and (vi) selling expenses incurred at Zerust Brazil of $233,000. Selling expenses as a percentage of net sales decreased to 19.3% during the three months ended February 28, 2011, from 20.4% during the three months ended February 28, 2010, due to smaller proportional increases in selling expenses, compared to the increases in net sales. Selling expenses as a percentage of net sales increased slightly to 21.6% during the six months ended February 28, 2011, from 21.2% during the six months ended February 28, 2010, due to slightly larger proportional increases in selling expenses, compared to the increases in net sales.

General and Administrative Expenses. NTIC’s general and administrative expenses increased 27.5% for the three months ended February 28, 2011 compared to the same period in fiscal 2010 due to increases in (i) compensation and related benefits of $150,000 and (ii) general and administrative expenses incurred at Zerust Brazil of $110,000, partially offset by decreases in consulting expenses of $12,000 and auditing and tax expense of $41,000. NTIC’s general and administrative expenses increased 23.6% for the six months ended February 28, 2011compared to the same period in fiscal 2010 due to increases in (i) compensation and related benefits of $160,000 and (ii) general and administrative expenses incurred at Zerust Brazil of $216,000, partially offset by decreases in consulting expenses of $12,000. As a percentage of net sales, general and administrative expenses decreased to 22.4% and 24.5% for the three and six months ended February 28, 2011,respectively, from 29.2% and 31.5% for the three and six months ended February 28, 2010,respectively, primarily as a result of fixed general and administrative expenses spread over increased net sales.

Expenses Incurred in Support of Joint Ventures. Expenses incurred in support of NTIC’s joint ventures were $249,275 and $477,996 during the three and six months ended February 28, 2011, respectively, compared to $229,474 and $474,384 during the three and six months ended February 28, 2010, representing a increase of 8.6% and 0.8%, respectively.

Research and Development Expense. NTIC’s research and development expenses decreased 4.9% for the three months ended February 28, 2011 compared to the same period in fiscal 2010 due to a decrease in consulting expenses of $131,000; partially offset by increases in (i) salary and benefits of $65,000; and (ii) lab testing related expenses of $112,000. NTIC’s research and development expenses increased 34.2% for the six months ended February 28, 2011 compared to the same period in fiscal 2010 due to increases in (i) salary and benefits of $177,000; and (ii) lab testing related expenses of $194,000; partially offset by a decrease in consulting expenses of of $95,000.

Interest Income. NTIC’s interest income decreased to $676 and $4,609 during the three and six months ended February 28, 2011, respectively, compared to $3,247 and $4,743 during the three and six months ended February 28, 2010, respectively, primarily due to decreased cash balances earning interest and decreased interest rates during the most recent periods.

Interest Expense. NTIC’s interest expense decreased to $22,241 and $45,475 during the three and six months ended February 28, 2011, respectively, compared to $23,783 and $49,770 during the three and six months ended February 28, 2010, respectively, primarily due to the refinancing of NTIC’s term loan and its decreased term loan balance during the most recent periods.

Income Before Income Tax Expense. Income before income tax expense increased to $1,141,219 and $2,158,093 for the three and six months ended February 28, 2011, respectively, compared to $252,641 and $673,346 for the three and six months ended February 28, 2010, respectively.

Income Tax Expense (Benefit). Income tax expense was $140,000 and $262,000 during the three and six months ended February 28, 2011, respectively, compared to income tax benefit of $(94,000) and $(109,000) during the three and six months ended February 28, 2010, respectively. Income tax expense was calculated based on management’s estimate of NTIC’s annual effective income tax rate. NTIC’s annual effective income tax rate during the six months ended February 28, 2011 and 2010 was lower than the statutory rate primarily due to NTIC’s equity in income of joint ventures being recognized based on after-tax earnings of these entities. To the extent undistributed earnings of NTIC’s joint ventures are distributed to NTIC, it is not expected to result in any material additional income tax liability after the application of foreign tax credits. NTIC determined based on all available evidence, including historical data and projections of future results, that it is more likely than not that all of its deferred tax assets, except for its foreign tax credit carryforward and Minnesota state research and development credit carryforwards, will be fully realized and that NTIC’s deferred tax asset related to foreign tax credit carryforwards will not be realized due to insufficient federal taxable income within the carryforward period and the fact that for ordering purposes the foreign tax credit carryforwards are not allowed to be used until after any current year foreign tax credits are utilized.

Liquidity and Capital Resources

Sources of Cash and Working Capital. As of February 28, 2011, NTIC’s working capital was $9,267,637, including $1,864,215 in cash and cash equivalents, compared to working capital of $5,918,923, including $1,776,162 in cash and cash equivalents, as of August 31, 2010.

In connection with the purchase of its corporate headquarters, in September 2006, Northern Technologies Holding Company, LLC (“NTI LLC”) obtained a term loan from PNC Bank with a principal amount of $1,275,000 that was to mature on May 1, 2011. On January 10, 2011, NTI LLC refinanced its term loan in the then principal amount of approximately $1,141,788. The term loan matures on January 10, 2016, bears interest at an annual rate based on the daily LIBOR rate plus 2.15% and is payable in 59 consecutive monthly installments equal to approximately $6,343 (inclusive of principal but exclusive of interest) commencing in February 2011. The term loan is secured by a first lien on the real estate and building owned by NTI LLC and all of the assets of NTIC and is guaranteed by NTIC.

As of February 28, 2011, NTIC had a revolving line of credit with PNC Bank of $3,000,000 with no amounts outstanding as of such date. As of August 31, 2010, NTIC had a demand line of credit of $2,300,000 with PNC Bank with no amounts outstanding as of such date. The increased line of credit is evidenced by an amended and restated committed line of credit note in the principal amount of up to $3,000,000. The line of credit has a $1,200,000 standby letter of credit subfacility, with any standby letters of credit issued thereunder being at the sole discretion of PNC Bank. Any standby letters of credit issued under the subfacility are subject to customary fees and charges payable by NTIC. Advances made under the line of credit are due and payable on January 10, 2012. At the option of NTIC, outstanding advances under the line of credit bear interest at either (a) an annual rate based on LIBOR plus 2.15% for the applicable LIBOR interest period selected by NTIC or (b) at the rate publicly announced by PNC Bank from time to time as its prime rate. Interest is payable in arrears (a) for the portion of advances bearing interest under the prime rate on the last day of each month during the term thereof and (b) for the portion of advances bearing interest under the LIBOR option on the last day of the respective LIBOR interest period selected for such advance. Any unpaid interest is payable on the maturity date.

Both the term loan and the line of credit are governed under two separate loan agreements. The loan agreements contain standard covenants, including affirmative financial covenants, such as the maintenance of a minimum fixed charge coverage ratio, and negative covenants, which, among other things, limit the incurrence of additional indebtedness, loans and equity investments, disposition of assets, mergers and consolidations and other matters customarily restricted in such agreements. Under the loan agreements, NTIC is subject to a minimum fixed charge coverage ratio of 1.10:1.00.

NTIC believes that a combination of its existing cash and cash equivalents, forecasted cash flows from future operations, anticipated distributions of earnings, anticipated fees to NTIC for services provided to its joint ventures, and funds available through existing or anticipated financing arrangements, will be adequate to fund its existing operations, investments in new or existing joint ventures, capital expenditures, debt repayments and any stock repurchases for at least the next 12 months. During the remainder of fiscal 2011, NTIC expects to continue to invest in research and development and in marketing efforts and resources into its new businesses, product lines and markets, including in particular the application of its corrosion prevention technology into the oil and gas industry. In order to take advantage of such new product and market opportunities to expand its business and increase its revenues, NTIC may decide to finance such opportunities by borrowing under its revolving line of credit or raising additional financing through the issuance of debt or equity securities. There is no assurance that any financing transaction will be available on terms acceptable to NTIC or at all, or that any financing transaction will not be dilutive to NTIC’s current stockholders.

NTIC traditionally has used the cash generated from its North American operations, distributions of earnings and fees for services provided to its joint ventures to fund NTIC’s new technology investments and capital contributions to new and existing joint ventures. NTIC’s joint ventures traditionally have operated with little or no debt and have been self-financed with minimal initial capital investment and minimal additional capital investment from their respective owners. Therefore, NTIC believes it is not likely that there exists any exposure to debt by NTIC’s joint ventures that could materially impact their respective operations and/or liquidity.

Uses of Cash and Cash Flows. Net cash used in operating activities during the six months ended February 28, 2011 was $2,416,393 which resulted principally from NTIC’s equity in income from joint ventures and increases in receivables, inventories and prepaid expenses and a decrease in accounts payables, partially offset by NTIC’s net income and increases in income taxes payable and accrued liabilities. Cash flows used in operations for the six months ended February 28, 2010 was $1,286,287, which resulted principally from equity income of corporate joint ventures, an increase in inventory and trade receivables including corporate joint ventures, offset by net income, depreciation and amortization expense, stock option expense, decrease in technical and other services receivables from corporate joint ventures, and an increase in accounts payable and accrued liabilities.

NTIC’s cash flows from operations are impacted by significant changes in certain components of NTIC’s working capital, including inventory turnover and changes in receivables. NTIC considers internal and external factors when assessing the use of its available working capital, specifically when determining inventory levels and credit terms of customers. Key internal factors include existing inventory levels, stock reorder points, customer forecasts and customer requested payment terms, and key external factors include the availability of primary raw materials and sub-contractor production lead times. NTIC’s typical contractual terms for trade receivables excluding joint ventures are traditionally 30 days and for trade receivables from its joint ventures is 90 days. Before extending unsecured credit to customers, excluding NTIC’s joint ventures, NTIC reviews customers’ credit histories and will establish an allowance for uncollectible accounts based upon factors surrounding the credit risk of specific customers and other information. Accounts receivable over 30 days are considered past due for most customers. NTIC does not accrue interest on past due accounts receivable. If accounts receivables in excess of the provided allowance are determined uncollectible, they are charged to selling expense in the period that determination is made. Accounts receivable are deemed uncollectible based on NTIC exhausting reasonable efforts to collect. NTIC’s typical contractual terms for receivables for services provided to its joint ventures are 90 days. NTIC records receivables for services provided to its joint ventures on an accrual basis, unless circumstances exist that

make the collection of the balance uncertain in which case the fee income will be recorded on a cash basis until there is consistency in payments. This determination is handled on a case by case basis.

NTIC experienced an increase in inventory as of February 28, 2011 compared to August 31, 2010 due to the increase in net sales during the most recent period and requests from customers to stock more products to shorten lead times and meet customer demand. Trade receivables excluding joint ventures as of February 28, 2011 increased $901,627 compared to August 31, 2010, primarily related to the increase in sales and the consolidation of Zerust Brazil.

Outstanding trade receivables excluding joint ventures balances as of February 28, 2011 increased 29 days to an average of 69 days from balances outstanding from these customers as of August 31, 2010.

Outstanding trade receivables from joint ventures as of February 28, 2011 increased $95,677 compared to August 31, 2010, primarily due to the corresponding increase in net sales to joint ventures, which also resulted in an decrease of outstanding balances from trade receivables from joint ventures as of February 28, 2011 of 66 days to an average of 172 days from balances outstanding from these customers as of August 31, 2010. The significant average days outstanding of trade receivables from joint ventures as of February 28, 2011 were primarily due to the current receivable balance at NTIC’s joint venture in India. NTIC has made separate arrangements for payments on product that NTIC’s joint venture in India has purchased from NTIC until the product is sold.

Outstanding fees for services provided to joint ventures as of February 28, 2011 increased $380,292 as compared to August 31, 2010, primarily resulting from increased joint venture sales. These higher fees for the six months ended February 28, 2011 resulted in an increase of 12 days of fees receivable outstanding as of February 28, 2011 to an average of 108 days as compared to August 31, 2010.

Net cash provided by investing activities for the six months ended February 28, 2011 was $2,092,028 which was comprised of dividends received from joint ventures and proceeds from sale of property and equipment partially offset by additions to property and equipment, additions to patents and investments in joint ventures. Net cash used in investing activities for the six months ended February 28, 2010 was $1,978 which due primarily to additions to patents, additions to property and equipment, partially offset by dividends received from joint ventures.

Net cash provided by financing activities for the six months ended February 28, 2011 was $403,009, which resulted from proceeds from option exercises and NTIC’s employee stock purchase plan, partially offset by principal payments on the bank loan for NTIC’s corporate headquarters buildings. Net cash provided by financing activities for the six months ended February 28, 2010 was $2,483,769, which resulted primarily from the issuance of common stock and, to a lesser extent, proceeds from NTIC’s employee stock purchase plan and option exercises, partially offset by repayments to NTIC’s prior demand line of credit and principal payments on the bank loan for its corporate headquarters buildings.

Capital Expenditures and Commitments. NTIC had no material lease or other material capital commitments as of February 28, 2011, except a lease agreement for approximately 16,994 square feet of office, manufacturing, laboratory and warehouse space in Beachwood, Ohio, requiring monthly payments of $17,500, which are adjusted annually according to the annual consumer price index, through November 2014. In January 2011, NTI Facilities, Inc. sold its membership interest in Omni-Northern Ltd., which owned the building, for $100,000. This resulted in a net gain of $47,575 after the write-off of various leasehold improvements.

NTIC has no postretirement benefit plan and does not anticipate establishing any postretirement benefit program in the near future.

Off-Balance Sheet Arrangements

NTIC does not have any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet financial arrangements. As such, NTIC is not materially exposed to any financing, liquidity, market or credit risk that could arise if NTIC had engaged in such arrangements.

Inflation and Seasonality

Inflation in the U.S. and abroad historically has had little effect on NTIC. NTIC’s business has not historically been seasonal.

Market Risk

NTIC is exposed to some market risk stemming from changes in foreign currency exchange rates, commodity prices and interest rates.

Because the functional currency of NTIC’s foreign operations and investments in its foreign joint ventures is the applicable local currency, NTIC is exposed to foreign currency exchange rate risk arising from transactions in the normal course of business. NTIC’s principal exchange rate exposure is with the Euro, the Japanese yen, Indian Rupee, Chinese yuan, Korean won and the English pound against the U.S. dollar. NTIC’s fees for services provided to joint ventures and dividend distributions from these foreign entities are paid in foreign currencies and thus fluctuations in foreign currency exchange rates could result in declines in NTIC’s reported net income. Since NTIC’s investments in its joint ventures are accounted for using the equity method, any changes in foreign currency exchange rates would be reflected as a foreign currency translation adjustment and would not change NTIC’s equity in income of joint ventures reflected in its consolidated statements of income. NTIC does not hedge against its foreign currency exchange rate risk.

Some raw materials used in NTIC’s products are exposed to commodity price changes. The primary commodity price exposures are with a variety of plastic resins.

At the option of NTIC, outstanding advances under NTIC’s $3,000,000 revolving line of credit with PNC Bank bear interest at either (a) an annual rate based on LIBOR plus 2.15% for the applicable LIBOR interest period selected by NTIC or (b) at the rate publicly announced by PNC Bank from time to time as its prime rate, and thus may subject NTIC to some market risk on interest rates. As of February 28, 2011, NTIC had no borrowings under the line of credit.

Critical Accounting Policies and Estimates

There have been no material changes to NTIC’s critical accounting policies and estimates from the information provided in “Part II. Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies”, included in NTIC’s annual report on Form 10-K for the fiscal year ended August 31, 2010.

In addition, NTIC or others on NTIC’s behalf may make forward-looking statements from time to time in oral presentations, including telephone conferences and/or web casts open to the public, in press releases or reports, on NTIC’s Internet web site or otherwise. All statements other than statements of historical facts included in this report or expressed by NTIC orally from time to time that

address activities, events or developments that NTIC expects, believes or anticipates will or may occur in the future are forward-looking statements including, in particular, the statements about NTIC’s plans, objectives, strategies, the outcome of contingencies such as legal proceedings, and prospects regarding, among other things, NTIC’s financial condition, results of operations and business.

The use of future dates is also an indication of a forward-looking statement. Forward-looking statements may be contained in the notes to NTIC’s consolidated financial statements and elsewhere in this report, including under the heading “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Forward-looking statements are based on current expectations about future events affecting NTIC and are subject to uncertainties and factors that affect all businesses operating in a global market as well as matters specific to NTIC. These uncertainties and factors are difficult to predict and many of them are beyond NTIC’s control. The following are some of the uncertainties and factors known to us that could cause NTIC’s actual results to differ materially from what NTIC has anticipated in its forward-looking statements:

·	The effect of current worldwide economic conditions on NTIC’s business;

·	The health of the U.S. automotive industry on NTIC’s business;

·	NTIC’s investments in its new business and research and development efforts and its need for additional capital to support such new business and research and development efforts;

The success of and risks associated with NTIC’s emerging new businesses and products and services, including in particular NTIC’s ability and the ability of NTIC’s joint ventures to sell ZERUST® products and services into oil and gas industry and Natur-Tec® products and the often lengthy and extensive sales process involved in selling such products and services;

·	NTIC’s ability to introduce new products and services that respond to changing market conditions and customer demand;

·	Market acceptance of NTIC’s existing and new products, especially in light of existing and new competitive products;

·	Maturation of certain existing markets for NTIC’s ZERUST® products and services and NTIC’s ability to grow market share and succeed in penetrating other existing and new markets;

·	Increased competition, especially with respect to NTIC’s ZERUST® products and services, and the effect of such competition on NTIC’s and its joint ventures’ pricing, net sales and margins;

·	NTIC’s reliance upon and its relationships with its distributors, independent sales representatives and joint ventures;

·	NTIC’s reliance upon suppliers, including in particular its single supply source for its base bioplastics resins;

·	The costs and effects of complying with laws and regulations and changes in tax, fiscal, government and other regulatory policies, including rules relating to environmental, health and safety matters;

·	The costs and effects of currently outstanding or threatened litigation;

·	Unforeseen product quality or other problems in the development, production and usage of new and existing products;

·	Loss of or changes in executive management or key employees;

·	Ability of management to manage around unplanned events;

·	NTIC’s reliance on its intellectual property rights and the absence of infringement of the intellectual property rights of others;

·	Fluctuations in NTIC’s effective tax rate; and

·	NTIC’s reliance upon its management information systems.

For more information regarding these and other uncertainties and factors that could cause NTIC’s actual results to differ materially from what NTIC has anticipated in its forward-looking statements or otherwise could materially adversely affect its business, financial condition or operating results, see NTIC’s annual report on Form 10-K for the fiscal year ended August 31, 2010 under the heading “Part I. Item 1A. Risk Factors.”

All forward-looking statements included in this report are expressly qualified in their entirety by the foregoing cautionary statements. NTIC wishes to caution readers not to place undue reliance on any forward-looking statement that speaks only as of the date made and to recognize that forward-looking statements are predictions of future results, which may not occur as anticipated. Actual results could differ materially from those anticipated in the forward-looking statements and from historical results, due to the uncertainties and factors described above, as well as others that NTIC may consider immaterial or does not anticipate at this time. Although NTIC believes that the expectations reflected in its forward-looking statements are reasonable, NTIC does not know whether its expectations will prove correct. NTIC’s expectations reflected in its forward-looking statements can be affected by inaccurate assumptions NTIC might make or by known or unknown uncertainties and factors, including those described above. The risks and uncertainties described above are not exclusive and further information concerning NTIC and its business, including factors that potentially could materially affect its financial results or condition, may emerge from time to time. NTIC assumes no obligation to update, amend or clarify forward-looking statements to reflect actual results or changes in factors or assumptions affecting such forward-looking statements. NTIC advises you, however, to consult any further disclosures NTIC makes on related subjects in its annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K NTIC files with or furnishes to the Securities and Exchange Commission.
