FORWARD-LOOKING STATEMENTS

Except for any historical information contained herein, the matters discussed in this Annual Report on Form 20‑F contain certain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995 with respect to our financial condition, results of operations and business. These statements relate to analyses and other information which are based on forecasts of future results and estimates of amounts not yet determinable. These statements also relate to our future prospects, developments and business strategies. These forward-looking statements are identified by their use of terms and phrases such as “anticipate”, “believe”, “could”, “estimate”, “expect”, “intend”, “may”, “plan”, “predict”, “will” and similar terms and phrases, including references to assumptions. These forward-looking statements involve risks and uncertainties, including current trend information, projections for deliveries and other trend projections, that may cause our actual future activities and results of operations to be materially different from those suggested or described in this Annual Report on Form 20-F.

These risks include:

· our ability to generate sufficient cash flow from operations or to raise adequate capital to allow us to continue as a going concern;

· conducting operations in international markets;

· the availability, on a charter-hire basis, of suitable aircraft used in conducting our operations;

· the emergence of alternative competitive technologies;

· protection of our intellectual property and rights to our SFD® technology;

· the loss of key personnel;

· our dependence on a limited number of clients;

· foreign currency and interest rate fluctuations may affect our financial position;

· volatility in oil and natural gas commodity prices may reduce demand for our services; and

· other factors described herein under “Risk Factors” (see Item 3 D).

If one or more of these risks or uncertainties materialize, or if underlying assumptions prove incorrect, our actual results may vary materially from those expected, estimated or projected. Given these uncertainties, users of the information included in this Annual Report on Form 20-F, including investors and prospective investors, are cautioned not to place undue reliance on such forward-looking statements. We do not intend to update the forward-looking statements included in this Annual Report on Form 20-F.

In this Annual Report on Form 20-F, except as specified otherwise or unless the context requires otherwise, “we”, “our”, “us”, the “company”, and “NXT” refer to NXT Energy Solutions Inc. and its subsidiaries. All references to “fiscal” in connection with a year shall mean the year ended December 31.

All financial information contained herein is expressed in Canadian dollars (“Cdn$”) unless otherwise stated.

D. Risk factors

Investing in our common shares involves a high degree of risk. In addition to the other information included in this document, you should carefully consider the risks described below before purchasing our common shares. If any of the following risks actually occur, our business, financial condition and results of operations could materially suffer. As a result, the trading price of our common shares could decline and you might lose all or part of your investment.

Our ability to continue operating is not certain.

The company is in the early stage of commercializing its SFD® technology. Its ability to generate cash flow from operations will depend on its ability to service its existing clients and develop new clients to purchase its SFD® services. Management recognizes that this early commercialization phase can last for several years. Consistent with this early stage of commercialization the company has a significant economic dependency on a limited number of clients. While the company is in this early stage of commercialization, the company’s financial position is materially impacted by the loss or gain of any one client. The company's ability to continue operations is dependent on attracting future customers through demonstrating the value that the company can bring to the customer’s exploration activities, and on obtaining financing (if and when needed).

Until we can demonstrate our ability to continue to service existing clients and develop new clients for our SFD® services over a longer period of time, we cannot be certain that we are in a position to continue operating indefinitely. The company’s ability to continue as a going concern is discussed within Note 1 of the consolidated financial statements that are incorporated by reference within this Form 20-F.

As the company is in the early commercialization phase, SFD® surveys have not been tested over all potential geological conditions. Some geological conditions may subsequently be proven to be unsuited for SFD® surveys thereby creating unforeseen limitations to the application of SFD® surveys.

Any limitation to the application of SFD® surveys has the potential of restricting future revenue opportunities and if not properly disclosed to industry clients, such limitations may impact the reputation of the company with these clients.

The financial statements rely upon estimates and assumptions that could be incorrect.

The preparation of financial statements requires our management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities including the disclosure of contingent assets and liabilities as well as revenues and expenses recorded in our financial statements. Estimates made relate to allowances for doubtful accounts, estimated useful lives of assets, provisions for contingent liabilities, measurement of stock-based compensation expense, valuation of derivative instruments and equity and future income tax assets, estimates for asset retirement obligations, and the valuation of preferred shares (which may include estimates of the likelihood that the conversion feature of the preferred shares will be achieved in future).

The estimates and assumptions are reviewed periodically and are based upon the best information available to management, however, we cannot provide assurance that future events will not prove that these estimates and assumptions are inaccurate. Any revisions to our estimates and assumptions may have a material impact on our future reported net income or loss, and assets or liabilities.

7 20-F for the year ended December 31, 2012

We may engage in transactions with related parties.

NXT may periodically enter into related party transactions with its officers and directors. The most significant transaction was a “Technical Transfer Agreement” (the “TTA”) that was executed on December 31, 2006 between NXT and Mr. George Liszicasz, our Chief Executive Officer (“CEO”), president and director, wherein NXT issued 10,000,000 convertible preferred shares in exchange for the acquisition of the SFD® technology for use in hydrocarbon exploration. See also item 7B.

Although NXT manages this conflict of interest risk through maintenance of a strong independent board of directors (the “board”), all related party transactions have the potential for conflicts of interest that may compromise the ability of board members to exercise their fiduciary responsibility to NXT shareholders.

Volatility in oil and natural gas price commodity prices may affect demand for our services.

We incur a risk of market changes in oil and natural gas prices. Prospective revenues from the sale of our services can be impacted by oil and natural gas prices changes. The impact of price changes on our ability to enter into SFD® survey contracts cannot be readily determined; however, in general if commodity prices decline significantly, our opportunity to obtain and execute SFD® survey contract will also likely decline.

Our financial position is affected by foreign currency fluctuations.

We currently conduct cash transactions, and have holdings in Canadian dollars, U.S. dollars and Colombian pesos. We currently earn revenues in U.S. dollars, and potentially may earn revenues in Canadian dollars and other foreign currencies. Our reporting currency is in Canadian dollars. We currently do not engage in currency hedging activities. Our cash positions and potential foreign currency revenue streams in currencies other than Canadian dollars exposes us to exchange rate fluctuations between the Canadian dollar and foreign currencies. See Item 11.

Our financial position will be affected by exchange rate fluctuations. We may earn revenue and incur expenses denominated in foreign currencies, yet report our financial results in Canadian dollars. Furthermore we intend to enter into contracts to provide services in foreign countries and may conduct business in other currencies such as the Euro. Changes in currency exchange rates could have an adverse effect on the company's business, financial condition and results of operations.

Our net income or loss is impacted by interest rate fluctuations.

We periodically invest available cash in short term investments that generate interest income that will be affected by any change in interest rates. See Item 11.

We rely upon the availability of charter aircraft to conduct our survey operations.

NXT currently does not currently own any aircraft, and relies upon the availability of aircraft which is operated under charter hire arrangements. Charter operators provide the aircraft used in SFD® survey operations on an as required basis in exchange for an hourly charter fee (plus fuel and other direct operating costs). NXT is not required to make a capital investment in chartered aircraft, but in order to guarantee aircraft availability and rate certainty, it currently commits to a one year contract, with a minimum number of charter hours. NXT is thus exposed to potential financial penalty in the event that it fails to fulfill the minimum annual charter hours commitment.

In 2009 we entered into a charter agreement with Air Partners Corp., a Calgary, Alberta based international aircraft charter operator, to supply aircraft services for our survey requirements. This agreement is being renewed on an annual basis and now covers a period expiring January 11, 2014. This original agreement has been included in this Form 20-F as Exhibit No. 4.43.

8 20-F for the year ended December 31, 2012

Although various charter operators have provided aircraft charter services since the disposal in 2003 of a previously owned aircraft, there is a risk that suitable aircraft may not be available from charter operators when needed.

If a chartered aircraft is not available then NXT may have no option but to purchase a company owned aircraft and then engage a third party to operate the aircraft. A future requirement to acquire an aircraft would place significant strain on the financial and operational resources of the company. There is a risk that the company would not have the financial resources or operational capacity to acquire an aircraft within an acceptable time frame to meet operational requirements.

In the future, should we be unable to receive aircraft services from a suitable charter operator and should we be unable to acquire an alternative suitable aircraft in a timely fashion, we would be unable to conduct SFD® surveys for clients and this inability would have a material adverse effect on the company's business, financial condition and results of operations.

We are a small business with limited personnel and our inability to segregate duties between administrative staff is an internal control weakness.

Certain duties that are most appropriately segregated between different employees are, due to our current limited staff, assigned to one individual.

Standard internal control methodology involves the separation of incompatible functions by assigning these functions to separate individuals, and in larger organizations, to separate departments. We often cannot allocate these functions to separate individuals because our administrative staff is too small.

Although the company has adopted alternative control methods designed to compensate for the reduced ability to separate incompatible functions these alternative controls are not effective and there is more than a remote likelihood that our internal control over financial reporting will not prevent or detect material misstatements if they should exist in our financial statements. This lack of separation of duties exposes the company to potential misappropriation of funds, embezzlement and other forms of fraud and could have a material adverse effect on the company's business, financial condition and results of operations. See also Item 15 included herein.

Our rights to SFD® technology may be challenged and we may need to defend our rights to the technology in the courts.

Our rights to ownership and use of SFD® technology depends on Mr. Liszicasz ,our President & CEO and a director,  having the lawful right to sell to NXT the exclusive rights to exploit the SFD® technology for the exploration of hydrocarbons as agreed to in the Technical Transfer Agreement (“TTA”). (For a full history of the TTA see Item 4.A Information on the Company - History and development of the companyincluded herein).

On December 31, 2006 we executed the TTA with Mr. Liszicasz whereby Mr. Liszicasz transferred to NXT all his rights to the SFD® technology for the purpose of hydrocarbon exploration.

A risk does exist that an unknown party may claim some legal entitlement to Mr. Liszicasz’ intellectual property, NXT’s rights to commercialize this intellectual property or NXT’s right to create SFD® devices and processes. However, we believe that such a claim would be without merit.

The SFD® technology is an essential component of our business plan. If a third party challenged our lawful entitlement to this technology, the legal defense of our right to the technology may be expensive and could cause a loss of our right to the SFD® technology, or a protracted legal process to assert our right to the technology would have a material adverse effect on the company's business, financial condition and results of operations.

9 20-F for the year ended December 31, 2012

We rely on specialized equipment, including a limited number of SFD® sensors, and this limitation may affect our ability to conduct business.

We rely on specialized data acquisition equipment, including a limited number of SFD® sensor devices, to conduct our aerial SFD® survey operations. The company would be at risk if these survey sensors were to become damaged, destroyed, worn out, stolen or in any way became unavailable for use in operations prior to us creating and testing additional sensors. Should the sensors become unavailable for any reason, our ability to conduct surveys could be delayed for several months as we built new sensors. During this period we may become unable to satisfy contractual obligations, which may jeopardize future revenue opportunities and may potentially result in a client drawing on a performance bond posted or otherwise making claims against the company for breach of contract. In addition, an inability to satisfy contractual obligations may have an adverse effect on our developing reputation within the oil and gas community.

Unless we pursue ongoing technological improvement and development we may be unable to respond to changes in customer requirements or new competitive technologies.

We must continue to refine and develop our SFD® survey system to make it scalable for growth and to respond to potential future competitive pressures. These improvements require substantial time and resources. Furthermore, even if resources are available, there can be no assurance that the company will be commercially or technically successful in enhancing the technology. The company’s inability to keep pace with new technologies and evolving industry standards and demands could have a material adverse effect on the company's business, financial condition and results of operations.

We are dependent on key personnel and the loss of any of these key persons will impact our ability to conduct business.

The company's future success depends to a significant extent on the continued service of its key technical and management personnel and on its ability to continue to attract and retain qualified employees. The loss of the services of the company's employees or the company's failure to attract, retain and motivate qualified personnel could have a material adverse effect on the company's business, financial condition and results of operations. We do not have “key man” insurance on any of our personnel.

The company puts in place employment agreements with all of its executive officers, including George Liszicasz, its president and CEO.

We have a dependence on Mr. Liszicasz to interpret the SFD® data and to enhance our technology. The company is working to minimize this dependency on one individual. Mr. Liszicasz has trained and continues to train a team of signal interpreters to minimize the company’s reliance on him to perform these functions. Currently a total of six persons, two of which are highly experienced, are trained to interpret SFD® signals.

Although the company has engaged employees with suitable credentials to work with Mr. Liszicasz to enhance our interpretation process and further develop the SFD® technology, if the company is unable to reduce dependence on Mr. Liszicasz and he becomes incapable of performing or unwilling to perform these functions, then there may be an adverse affect on our ability to interpret the data from SFD® surveys or to enhance our technology.

We rely on a limited number of employees and contractors who collectively possess the knowledge and skills to conducted SFD® surveys, interpret SFD® data and provide other services required to meet contract obligations. Additional or replacement personnel cannot be found and trained quickly. The loss of any of these key persons or increased demand for our services from clients could impair our ability to meet contract obligations, thereby adversely impacting our reputation and our ability to earn future revenue from clients.

Within the province of Alberta the skilled personnel that we require are in short supply and in addition there is specialized training required that can take several months in order for a new employee to become effective. If we cannot hire these key personnel, we have inadequate time to train them or should we lose current personnel, then our ability to accept contracts or meet contract commitments may be adversely affected thereby restricting our ability to earn revenue.

10 20-F for the year ended December 31, 2012

A single major shareholder who is also a board member and an officer of the company retains the ability to influence or control the company and this influence or control may result in a conflict of interest.

Mr. George Liszicasz, our principal executive officer and largest shareholder, as of April 16, 2013, owns, approximately 13% of the common shares outstanding and therefore has a substantial influence in all shareholder matters. Additionally, he holds 10,000,000 convertible preferred shares, which are convertible on a one-to-one basis into NXT common shares. Of this total, 2,000,000 are currently convertible at the discretion of Mr. Liszicasz, and formal conversion has been requested to occur effective April 30, 2013. The remaining 8,000,000 preferred shares are convertible into common shares on or before December 31, 2015 subject to conditions including NXT meeting cumulative revenue milestones. If all 10,000,000 of the preferred shares were to be converted and there was no other change in our share structure he would own 31% of the then outstanding common shares. See Notes to the Consolidated Financial Statements or Item 4.B Information on the Company – Technical Transfer Agreement, for additional information relating to the preferred shares.

Controls do exist to mitigate any potential risks associated with this conflict of interest. Mr. Liszicasz adheres to a code of conduct which includes a fiduciary responsibility to the company and its shareholders and this conduct is governed by the independent board of directors who collectively represent a majority of the board. Furthermore all material related party transactions are disclosed publicly.

However, should these conflict of interest controls not be effective, decisions could be made by the company that may advantage Mr. Liszicasz and negatively impact other shareholders.

There is no certainty that an investor can trade our common shares on public markets at a stable market price.

There is a limited public market for our common shares on the TSX Venture Exchange (the “TSX-V”), and the United States ("U.S.") Over the Counter Exchange Bulletin Board (the “OTCBB”) and there is a risk that a broader or more active public trading market for our common shares will not develop or be sustained, or that current trading levels will not be sustained.

The market price for the common shares on the exchanges where our stock is listed has been, and we anticipate will continue to be, extremely volatile and subject to significant price and volume fluctuations in response to a variety of external and internal factors. This is especially true with respect to emerging companies such as ours. Examples of external factors, which can generally be described as factors that are unrelated to the operating performance or financial condition of any particular company, include changes in interest rates and worldwide economic and market conditions, as well as changes in industry conditions, such as changes in oil and natural gas prices, oil and natural gas inventory levels, regulatory and environment rules, and announcements of technology innovations or new products by other companies. Examples of internal factors, which can generally be described as factors that are directly related to our consolidated financial condition or results of operations, would include release of reports by securities analysts and announcements we may make from time to time relative to our operating performance, clients exploration results, financing, advances in technology or other business developments.

Because we have a limited operating history and a limited history of profitability to date, the market price for the common shares is more volatile than that of a seasoned issuer. Changes in the market price of the common shares, for example, may have no connection with our operating results or the quality of services provided to clients. No predictions or projections can be made as to what the prevailing market price for the common shares will be at any time, or as to what effect, if any, that the sale of shares or the availability of common shares for sale at any time will have on the prevailing market price. Given the relatively low historic trading volumes, small trades of the company’s common shares can adversely and potentially dramatically affect the market prices for those shares.

11 20-F for the year ended December 31, 2012

Accordingly investors in the company’s common stock should anticipate both volatile stock price and poor liquidity unless these conditions change.

You will be subject to the penny stock rules to the extent our stock price on the OTCBB is less than $5.00.

Since the common shares are not listed on a national stock exchange within the United States, trading in the common shares on the OTCBB is subject, to the extent the market price for the common shares is less than $5.00 per share, to a number of regulations known as the "penny stock rules". The penny stock rules, subject to certain exemptions, require a broker‑dealer to deliver a standardized risk disclosure document prepared by the Securities and Exchange Commission (the “SEC”), to provide the customer with additional information including current bid and offer quotations for the penny stock, the compensation of the broker‑dealer and its salesperson in the transaction, monthly account statements showing the market value of each penny stock held in the customer's account, and to make a special written determination that the penny stock is a suitable investment for the purchaser and to receive the purchaser's written agreement to the transaction. To the extent these requirements may be applicable they will reduce the level of trading activity in the secondary market for the common shares and may severely and adversely affect the ability of broker‑dealers to sell the common shares.

You should not expect to receive dividends in the foreseeable future.

We have never paid any cash dividends on our common shares and we do not anticipate that we will pay any dividends in the foreseeable future. Our current business plan is to retain any future earnings to finance the expansion of our business. Any future determination to pay cash dividends will be at the discretion of our board of directors, and will be dependent upon our consolidated financial condition, results of operations, capital requirements and other factors as our board of directors may deem relevant at that time.

Our right to issue additional capital stock at any time could have an adverse effect on your proportionate ownership and voting rights.

We are authorized under our Articles of Incorporation to issue an unlimited number of common shares and an unlimited number of preferred shares. We may issue these shares under such circumstances and in such manner and at such times, prices, amounts and purposes as our board of directors may, in their discretion, determine to be necessary and appropriate, subject to compliance with all applicable exchange regulations and corporate and securities laws. Proportionate ownership and voting rights of common shareholders could be adversely affected by the issuance of additional common shares which may result in common share value dilution.

We may not be able to protect our trade secrets and intellectual property from competitors who would use this knowledge to eliminate or reduce our technological advantage.

The company's success and future revenue growth will depend, in part, on its ability to protect its intellectual property (“IP”). We have commenced an IP strategy process, and intend to obtain patents related to the SFD® technology. The patent protection process would require disclosure of at least some aspects of our SFD® technology to third parties and ultimately public disclosure. This disclosure could significantly increase the risk of unlawful use of our technology by third parties. Furthermore we have no assurance that, even if we seek patent protection, a patent could be registered to protect our IP in all or any jurisdictions within North America or other countries throughout the world. If registered, there can be no assurance that it would be sufficiently broad to protect the company's technology or that any potential patent would not be challenged, invalidated or circumvented or that any right granted thereunder would provide meaningful protection or a competitive advantage to the company. Finally, protection afforded by patents is limited by the financial resources available to legally defend intellectual property rights. NXT currently does not possess the required financial resources to fund a lengthy defense of our rights if challenged by a much larger competitor or an oil and gas company.

12 20-F for the year ended December 31, 2012

We do enjoy common and contract law protection of our technology and trade secrets. Employees and contractors are governed by confidentiality agreements as well as a fiduciary responsibility to protect our technology, supporting documentation and other proprietary information.

Our strongest protection of the SFD® technology comes from restricting access to knowledge concerning the technology. Only a very limited number of NXT personnel have access to or knowledge of the underlying SFD® technology and no one employee and only one officer has access or knowledge of all aspects of the SFD® system. Currently no third party has any significant knowledge of the technology. As further protection, SFD® equipment does not leave the direct control of NXT employees, thereby preventing unauthorized replication of the equipment.

The company reassesses the appropriateness of its IP protection strategy on an ongoing basis and seeks advice from IP advisors as necessary.

It is possible that a third party will copy or otherwise obtain and use the company's technology without authorization, develop a similar technology independently or design around the company's secrets. Accordingly there can be no assurance that the steps taken by the company to prevent misappropriation or infringement of our IP will be successful.

An inability to protect our IP would make it possible for competitors to offer similar products and services that could have a material adverse effect on its business, financial condition and results of operations.

We experience operational hazards in our flight operations that may subject us to potential claims in the event that an incident or accident occurs.

The flight operations of SFD® surveys are subject to the hazards associated with general flight operations. An aircraft accident may cause personal injury and loss of life, as well as severe damage to and destruction of property, or the SFD® sensors and related equipment.

Independent third parties provide all the services required to maintain and operate the aircraft; they bear the primary risks of flight operations. These services are provided by an organization accredited by Transport Canada to operate aircraft in accordance with Transport Canada approved and audited operating procedures. The aircraft operator employs the required pilots, aircraft maintenance engineers and support personnel and ensures that they operate within their Transport Canada operating certificate. Our employees do not perform any airworthiness or flight safety operations.

We require the flight contractor to maintain appropriate insurance coverage for the risks associated with aircraft operations, and we obtain insurance coverage to provide us with additional risk protection. In addition, we maintain general business insurance coverage, and believe that this insurance and the policy limits are appropriate for the operational risks that we incur.

Despite our policy to not operate the aircraft directly and our insurance coverage, we cannot avoid or alternatively be insured for all risks of flight operations. In the event of an incident or accident we may be sued by injured parties in excess of our policy limits or for damages that are not covered by our insurance policy. The magnitude of a law suit of this nature is not determinable. Furthermore to the extent that our SFD® equipment is damaged we may be unable to conduct SFD® surveys for several months following an accident.

We are a Canadian company and our nationality may impair the enforceability of a judgment for any person resident outside Canada.

Since we are a Canadian company and most of our assets and key personnel are located in Canada, you may not be able to enforce a U.S. judgment for claims you may bring against us, our assets, our key personnel or many of the experts named in this document. This may prevent you from receiving compensation to which you may otherwise have a claim.

13 20-F for the year ended December 31, 2012

We are organized under the laws of Alberta, Canada and substantially all of our assets are normally located in Canada. In addition, virtually all of our board of directors and our officers are residents of Canada. As a result, it may be impossible for you to affect service of process upon us or these individuals within the U.S. or to enforce any judgments in civil and commercial matters, including judgments under U.S. federal securities laws. In addition, a Canadian court may not permit you to bring an original action in Canada or to enforce in Canada a judgment of a U.S. court based upon civil liability provisions of the U.S. federal securities laws.

We currently operate in countries such as Colombia and expect to perform services in other foreign countries in the future. Foreign operations expose us to several risks that may have a material adverse effect on the company.

Criminal Activity and Social Instability - Colombia over the past two decades has experienced significant social upheaval and criminal activity relating to drug trafficking, kidnapping and terrorist acts. While the situation has improved dramatically in recent years, there can be no guarantee that the situation will not deteriorate again nor are these risks eliminated as yet. Furthermore other potential international survey locations may have similar or other indeterminate criminal or social instability risks.

Systemic criminal activity in a country or isolated criminal acts may disrupt operations, impact the company's ability to earn revenue, dramatically add to our cost of operations or potentially prevent us from earning any survey revenue in a country.

In addition, foreign markets may be susceptible to a higher risk of corruption and bribery. All of NXT’s employees, contractors, and independent sales agents are required to adhere to the company’s code of conduct and business ethics, which prohibits illegal activities, including any acts of bribery or corruption.

Political Instability - Any changes in regulations or shifts in political attitudes are beyond the control of the company and may adversely affect its business. Exploration may be affected in varying degrees by government regulations which have the effect of restricting exploration and production activities. These changes may adversely impact the laws and policies governing price controls, export controls, foreign exchange controls, income taxes, expropriation of property, environmental legislation, site safety or other areas.

Currently there are no restrictions on the repatriation of our earnings in Colombia back to Canada; however, there can be no assurance that restrictions on repatriation of earnings from Colombia to Canada will not be imposed in the future.

Our operations may also be adversely affected by changes in laws and policies in Canada impacting foreign travel and immigration, foreign trade, taxation and investment.

Commercial Disputes – While operating in a foreign country we are subjected to local commercial laws which often involve executing contracts in a foreign language. Although every effort is made to ensure we have access to an accurate English translation, misunderstanding and potential disputes between parties may arise.

In the event of a dispute arising in connection with our foreign operations for any reason, we may be subject to the exclusive jurisdiction of foreign courts or may not be successful in subjecting foreign persons to the jurisdictions of the courts of Canada or enforcing Canadian judgments in such other jurisdictions. We may also be hindered or prevented from enforcing our rights with respect to a government instrumentality because of the doctrine of sovereign immunity.

14 20-F for the year ended December 31, 2012

Accordingly, these risk factors have the potential of adversely reducing the level of survey revenue from our clients, our ability to operate effectively or our ability to be paid for our services and may have a material adverse effect on the company’s financial position.

We rely upon the right to conduct airborne surveys in foreign countries. These foreign operations expose us to the risks that we will be prevented from conducting surveys when requested by clients.

The operation of our business, namely conducting aerial SFD® surveys and interpreting SFD® data, is not subject to material governmental or environmental regulation in Canada and the United States with the exception of flight rules issued by Transport Canada and the FAA governing the use of commercial aircraft, including rules relating to low altitude flights. The requirements in other countries vary greatly and may require permits and/or provide other restrictions to conducting flight operations in the country that may restrict our ability to perform SFD® surveys.

For example, in Colombia SFD® surveys must comply with additional requirements not encountered in Canada and the United States, including customs obligations and bonds related to the importation and exportation of the aircraft into Colombia, obtaining permits from the local aviation authority, and obtaining permits from the Colombian Air Force. NXT has successfully operated in Colombia in accordance with these requirements.

With our North America and International experience to date, we do not anticipate any government controls or regulations that will prevent timely completion of SFD® surveys. However, we may encounter government restriction in other countries that may impact or restrict our ability conduct surveys.

If we encounter government regulation and restrictions that impact or prevent us from conducting surveys in any country then we will not be able to earn revenue in the country and we may be exposed to forfeiting any performance bonds.

We caution that the factors referred to above and those referred to as part of particular forward-looking statements may not be exhaustive and that new risk factors emerge from time to time in our rapidly changing business environment.

ITEM 4. INFORMATION ON THE COMPANY

A. History and development of the company

We are a technology company focused on providing a service to oil and natural gas exploration clients using our proprietary SFD® survey system. The SFD® system is a remote sensing airborne survey system for the oil and gas exploration industry. SFD® and NXT® are both registered trademarks of NXT Energy Solutions Inc.

NXT was incorporated under the laws of the State of Nevada on September 27, 1994 and continued from the State of Nevada to the Province of Alberta, Canada on October 24, 2003.

Our registered office is located at Suite 1400, 505 - 3rd Street SW, Calgary, Alberta, Canada and our telephone number is (403) 264‑7020. In the United States our authorized agent is Parasec at: 318 North Carson Street, Suite 208, Carson City, NV and their telephone number is (888) 972-7273.

We are a reporting issuer in Alberta and British Columbia and are principally governed by the Alberta Securities Commission in accordance with the Securities Act (Alberta) and the Business Corporations Act (Alberta) (the “ABCA”). We are a foreign private issuer under United States securities laws and are subject to the regulation of the Securities and Exchange Commission of the United States ("SEC") in accordance with the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

The underlying technology employed by our SFD® survey system was invented by George Liszicasz, our President and CEO, chairman and largest shareholder. The technology was initially licensed to the company by Mr. Liszicasz until December 31, 2006 through a series of consecutive license agreements. On December 31, 2006 the company acquired the technology from Mr. Liszicasz pursuant to the TTA.

15 20-F for the year ended December 31, 2012

Upon execution of the TTA, Mr. Liszicasz transferred to the company all his rights and entitlements to the SFD® technology for use in the field of hydrocarbon exploration. Mr. Liszicasz has retained the rights to the technology for use in all other applications.

SFD® technology for the purposes of the TTA is defined as the theories of quantum physics and engineering which are utilized in the operation of stress field detectors used by NXT for the reception, collection and recording of subsurface geological stresses for hydrocarbon exploration. See also Item 4.B “Summary information on dependence on patents, licenses and contracts" for more information on this TTA agreement.

On February 9, 2010 the company registered a branch with both the Chamber of Commerce in Bogota, Colombia and with the office of Direction of Taxes and National Customs, the Colombian tax administration. The formation of this branch became a Colombian legal requirement following the company commencing permanent activity in Colombia in 2010 while conducting commercial survey operations.

The company’s business does not rely on significant capital expenditures. The company has made capital expenditures for property and equipment of $48,553, $38,975, and $55,516, respectively for the last three fiscal years 2012, 2011, and 2010. These expenditures relate largely to upgrades to office computer equipment and SFD® survey equipment.

The company does not currently have any significant capital expenditures in progress, or planned for the short term, for Canada or other international operations.

B. Business overview

Description of the nature of the company’s operations and principle activities

NXT utilizes its proprietary Stress Field Detection ("SFD®") survey system to provide a service for the oil and gas industry. SFD® is an airborne tool used for oil and gas exploration. We provide a fast and cost-effective method for our clients in the oil and natural gas industry to evaluate large land areas for their exploration potential.

SFD® sensors remotely respond to changes in subsurface stress regimes that are meaningful for oil and gas exploration. These responses are captured as raw data that, when interpreted, can provide an indirect method to detect the presence of geological features such as structure, faults, fractures and reefs that are often associated with traps and reservoir accumulations. SFD® is effective over wide areas where surveys often exceed 5,000 square kilometers. The SFD® survey system has been shown effective by clients to quickly focus exploration resources, offering the benefit of reducing the risk, time and expense associated with frontier exploration.

Following completion of the aerial surveys, NXT delivers to its clients a detailed report and maps of the surveyed area that identifies, ranks and recommends areas with SFD® indications of reservoir potential.

In 2006 the company commenced its current business model and began providing SFD® survey services to clients on a fee-for-service basis. In accordance with this model NXT will not invest either directly or indirectly in exploration or development wells or engage in other exploration or production activities. Our current business model minimizes our capital requirements thereby conserving cash, minimizes perceived or real conflicts between the interests of NXT and its survey clients and we believe will generate a higher return on capital for shareholders than if we adopted an oil and gas exploration and production business model.

Within our chosen business model our primary business is to earn revenues by conducting SFD® surveys for clients on a fee-for-service basis. Secondly, the company may negotiate to earn revenue from gross overriding royalty income and/or other incentive fees from clients should they generate production on areas recommended by SFD® surveys. Finally, in the future, the company may earn a fee by providing other related geological and geophysical integration services to clients.

16 20-F for the year ended December 31, 2012

Our objective with this business model is to obtain broad industry acceptance and appreciation of the value of our SFD® survey system. The main obstacle in achieving this objective is the oil and gas industry’s skepticism related to any early-stage technology. The industry has long memories of promising, but ultimately disappointing, technologies. Accordingly industry professionals are seldom prepared to devote resources or stake their professional reputation on an early stage technology. This reluctance is particularly acute when the fundamental science related to the technology is complex and not easily understood, as is the case with SFD®.

NXT’s strategy to overcome skepticism in order to gain industry acceptance of SFD® and maximize survey revenue fall into four general categories; maximizing client endorsement opportunities, providing industry education and support, targeting the most appropriate markets (i.e. where SFD® provides the maximum benefits) plus adopting an attractive and fair pricing structure. Our specific tactics are:

1. Focus the majority of sales resources on high profile primary markets which offer NXT the maximum opportunity for success (ex. Colombia);

2. Build upon success in this initial market, and step out to other markets (ex. Argentina, Peru, Brazil, Mexico) in Latin America;

3. Be opportunistic by responding selectively to requests of interest from qualified potential client "bluebirds" from all other locations in the world. The bluebird model is defined as an opportunity that arises, not from deliberate targeted sales initiatives, but in response to unsolicited client enquiries;

4. Capitalize on any bluebird sales by further soliciting sales opportunities within the bluebird market;

5. Continue to conduct small pilot surveys to expand our knowledge base and provide documentation to support the use of SFD® in new applications. Each new application opens more market opportunities and provides valuable case studies to support our sales initiatives; and

6. Respond to opportunities to present at technical conferences, publish papers in periodicals and generally maximize our opportunities to educate the industry on SFD® capabilities and document case study successes.

Description of the principle markets in which the company competes

Overview of markets

The company has an opportunity to provide its services to any region in the world that conducts oil and gas exploration activities. However, the company chooses to be strategic and focus its limited sales resources in its early stages of commercialization into just a few carefully selected markets.

North America Market

NXT began marketing of its SFD® survey system in 2006 largely in Canada and continued with this market focus until the end of 2008. Solely in Canada the company earned survey revenue of $1.2 million, $5.6 million, and $2.9 million respectively in the fiscal years 2006, 2007 and 2008.

There were no revenues generated in North America for 2009, 2010 or 2012.

In the second quarter of 2011 we completed a U.S. $150,000 contract to conduct a pilot SFD® survey in Montana for a Calgary based client. The purpose of the pilot survey is to utilize SFD® to provide indicators of trap and reservoir potential in a complex geological environment. The survey area contained both large blanket gas and small oil fields.

17 20-F for the year ended December 31, 2012

Colombian Market

In 2008 exploration activity seriously diminished in Canada as a result of the world-wide credit crisis and falling natural gas commodity prices. In response, the company looked to international markets for new revenue opportunities, which resulted in the company entering into the Colombian market in 2009. The company has now earned survey revenue in Colombia of $2.9 million in 2012, $0.4 million in 2010, and $3.7 million in 2009.

Colombia has many characteristics desirable for achieving market success for our SFD® survey system. With a business friendly approach and practical resource policies, Colombia attracts a large number of exploration and production companies from around the world. In Colombia there are obstacles to acquire geological and geophysical data as required to properly evaluate unexplored land. Obstacles include rain forests, environmental and community restrictions, security concerns and the high cost and time required to shoot seismic programs, particularly on-shore. SFD® can be a very effective tool to help overcome these obstacles.

Colombia has been primary international market focus in recent years. NXT is becoming well known in Colombia and we believe that it can continue to offer strong revenue opportunities.

South America and Central American Markets

NXT has been pursuing many countries within South America as attractive potential markets. Many of the companies active in Colombia are also active in other areas of South America, such as Peru, Bolivia, Argentina and Brazil. Many of these countries share a number of the same community, remote access and environmental issues that make SFD® an attractive solution.

In 2012, SFD® surveys were conducted in several new markets, including Argentina, Guatemala, Belize and most importantly Mexico. Our first contract with the National Oil Company of Mexico (PEMEX) was for U.S. $4.7 million, which was subsequently expanded before its completion to a total of U.S. $5.8 million. This was a significant milestone for the company, as it was our single largest contract to date, and it was able to be delivered in roughly 4 months.

South Asia Market

In late 2010 we started to negotiate a U.S. $2.66 million contract to conduct a survey in Pakistan. This opportunity arose through established prior relationships between our geophysical staff and key decision makers in the client’s exploration management. However, the contract was closed largely based upon case studies and client endorsements received from Colombian clients. Due to lengthy delays in securing approvals from all the relevant government bodies, the survey was not able to be commenced until late 2012, and was completed in the first quarter of 2013.

Description of seasonality of the company’s main business

There is no seasonality to the company’s business. It is however, a very cyclical business, as revenue activity is dependent upon the size and timing of a limited number of survey contracts each year.

Description of the source of raw material

We do not foresee any constraints upon materials or equipment that will impede our ability to execute our business plan or affect the company’s ability to conduct and/or expand its business. In order to conduct our survey operations we require the following:

• Survey aircraft - Historically NXT has both owned its own aircraft and chartered aircraft from independent charter aircraft companies.

In early 2009, in preparation for serving an international client base, we entered into a charter agreement with Air Partners Corp. (“Air Partners”), a Calgary based air-charter operator, to provide aircraft, crew and maintenance services for our survey operations worldwide. The current charter agreement with Air Partners has been extended for one year to January 11, 2014 whereupon the company anticipates that the agreement will likely be renewed on similar terms. Air Partners is a subsidiary of Morgan Air Services which has been providing aviation services worldwide since 1983. This agreement gives us priority access, on an as-needed basis, to at least two Citation 560 series jet aircraft that have been modified to meet our survey requirements. These jets are well suited for international operations.

18 20-F for the year ended December 31, 2012

• SFD® sensors - All of the survey sensors are manufactured in-house. Certain machining is required by third party machine shops, with final assembly performed by our technical staff. The sensors, once assembled, require flight testing prior to being considered acceptable for operational use. Not all sensors meet the performance criteria for operational use; however, NXT has demonstrated its ability to manufacture new functional SFD® sensors.
• SFD® assembly - The units in which the sensors are incorporated are custom designed, fabricated and assembled in-house or through subcontracted vendors. We utilize the services of Transport Canada approved Design Approval Representatives to prepare subsequent type certificates (“STC”) for the installation of our SFD® units in each aircraft that we utilize for surveys. The time to obtain an STC approval for the installation of our SFD® units into any proposed aircraft type may require several months.
• Computer hardware and software - (Data Acquisition System, SFD® Signal Conditioning Unit, and Interpretation Theatre) The customized software used in our data acquisition system is written and modified by outside consulting programmers with whom we have long‑standing relationships. The hardware we use in our SFD® survey systems (other than the SFD® unit), and the balance of the computer software we use, are all readily available from retail or wholesale sources.

We are not dependent upon any other third party contract manufacturers or suppliers to satisfy our technology requirements. We currently rely on Air Partners as a key supplier of the aircraft which we use in SFD® survey operations (see discussion below).

Description of marketing channels

The company largely uses direct sales methods with some use of commissioned sales representatives.

Summary information on dependence on patents, licenses and contracts

Patents

We have not yet patented our SFD® technology, however, we understand that we may be able to obtain worldwide patents in the future. In May 2012 the company commenced a “provisional” patent application process in the U.S, and intends to continue expanding this process into formal patent filings in the near term. We understand that our right to patent the SFD® technology in the future is not compromised by our ongoing commercial use of the technology, as the SFD® technology has never been disclosed to third parties (except under very limited confidential terms) or released in any manner into the public domain. See also Item 3.D Key Information – Risk factors.

Technical Transfer Agreement

Upon execution of the TTA on December 31, 2006 Mr. Liszicasz sold all his rights and entitlements to SFD® technology for use in the field of hydrocarbon exploration to the company in exchange for receiving 10,000,000 preferred shares. The preferred shares carry no voting rights.

2,000,000 of these preferred shares became immediately convertible on a one-to-one basis into common shares of the company at the discretion of the holder. In April, 2013, Mr. Liszicasz gave notice to NXT to formally convert (effective April 30, 2013) these 2,000,000 preferred shares into 2,000,000 common shares.

19 20-F for the year ended December 31, 2012

The remaining 8,000,000 preferred shares are convertible on a one-to-one basis into common shares should the company achieve the following cumulative revenue thresholds prior to the expiration of the TTA on December 31, 2015:

· 2,000,000 should cumulative gross revenue reach US $50 million,

· an additional 2,000,000 should cumulative gross revenue reach US $100 million,

· an additional 2,000,000 should cumulative gross revenue reach US $250 million, and

· an additional 2,000,000 should cumulative gross revenue reach US $500 million.

At December 31, 2015 the SFD® technology can be retained by the company by either:

· if the company earned cumulative aggregate gross revenue of US $500 million or more in the 9-year period ended December 31, 2015 then the company can choose to retain the SFD® technology by issuing Mr. Liszicasz an additional 1,000,000 common shares and converting all of the then outstanding preferred shares; or

· if the company did not earn cumulative aggregate gross revenue of US $500 million or more in the 9-year period ended December 31, 2015 then the company can choose to retain the SFD® technology by immediately converting all of the then outstanding preferred shares.

The Company has the option at December 31, 2015 to redeem any remaining unconverted preferred shares for a price of $0.001 per share and forfeit its rights to the SFD® technology, at which point it can be reacquired by Mr. Liszicasz for $10.00.

As at the current date April 16, 2013 the company has earned approximately US $26 million of cumulative gross revenue as defined in the TTA.

The following schedule provides a summary of the ownership of the preferred shares as of April 16, 2013:

Owner of Preferred Share	Preferred Shares Owned	Percent of Class of Share
George Liszicasz, President & CEO, and a Director	10,000,000	100.0%

See “Item 10.B – Memorandum and articles of association – Rights Attached to Preferred Shares – Conversion” below.

Second Amended and Restated Technical Services Agreement

This agreement was executed on December 31, 2006 outlining the terms of Mr. Liszicasz employment agreement with the company and establishes Mr. Liszicasz’ entitlement to normal employee remuneration such as salary, benefits, bonus and stock options and identifies grounds for termination of this agreement. This agreement has a term ending December 31, 2015 unless terminated by the company or Mr. Liszicasz. The Second Amended Services Agreement is included as Exhibit 4.36 to this Form 20-F.

Air Partners Aircraft Charter Agreement

On May 8, 2009, the company executed an aircraft charter agreement with Air Partners Corp. to provide aircraft, services for SFD® survey operations utilizing Air Partners’ fleet of Cessna Citation 560 series jet aircraft. The original term of this agreement was for a term of one year which has been extended through successive contract renewals. The current extension expires on January 11, 2014.

20 20-F for the year ended December 31, 2012

Under the terms of this agreement Air Partners shall provide aircraft charter services to meet NXT’s aircraft survey requirements both domestic and internationally. Specifically, Air Partners shall provide on a non-exclusive but preferential basis three Cessna Citation 560 aircraft, specifically modified to meet SFD® survey mission requirements. The Air Partners’ service shall include providing all aircraft personnel (including pilots, aircraft maintenance engineers and administration), insurance, aircraft maintenance, servicing and grooming all in accordance with Transport Canada and other regulatory standards.

NXT’s minimum aircraft charter commitment during the annual contract extension to January 11, 2014 has a value of approximately $317,000. The company’s commitment is based upon chartering in aggregate a minimum of 100 aircraft hours. Any flight hours that may become required in excess of this 100 hour minimum shall be made available to NXT for survey operations subject to aircraft and crew availability. As at April 16, 2013 the company has not yet met its annual 2013 charter hire commitment under this agreement.

The Air Partners Aircraft Charter Agreement dated January 11, 2011 is included as Exhibit 4.43 to this Form 20-F.

Basis for statements made regarding competitive position

Our SFD® airborne survey service is based upon a proprietary technology, which is capable of remotely identifying, from a survey aircraft, subsurface anomalies associated with potential hydrocarbon traps with a resolution that we believe is technically superior to other airborne survey systems. To our knowledge there is no other company employing technology similar or comparable to our SFD® survey system for oil and natural gas exploration.

Seismic is the standard technology used by the industry to image subsurface structures. It is our view that the SFD® survey system is a complementary technique to seismic. Our system may reduce the need for seismic in wide‑area reconnaissance but will not replace the role of seismic in verifying structure, closure and selecting drilling locations. The seismic industry is very competitive with many international and regional service providers.

The SFD® system can be used as a focusing tool for seismic. With an SFD® survey a large tract (i.e. over 5,000 square kilometers) of land can be evaluated quickly to identify locations with indications of reservoir potential. Seismic surveys, although effective in identifying these locations, are much more expensive, require significantly more time and impose a much greater negative impact on local communities and the environment. An SFD® survey deployed first can provide necessary information to target a seismic program over a limited area of locations selected by SFD®. This approach can result in a more effective seismic program and reduce the overall cost, time, community resistance and environmental impact required to locate and qualify a prospect.

The industry uses other technologies for wide area oil and natural gas reconnaissance exploration such as aeromagnetic and gravity surveys. These systems can provide regional geological information such as basement depth, sedimentary thickness and major faulting and structural development; however, these other airborne techniques are not as suitable for identifying areas with reservoir potential as the SFD® system.

Description of material effects of governmental & environmental regulation

SFD® Survey Flight Operations

The operation of our business, namely conducting aerial SFD® surveys and interpreting SFD® data, is not subject to material governmental or environmental regulation in Canada and the United States with the exception of flight rules issued by Transport Canada and the Federal Aviation Administration (“FAA”) governing the use of commercial aircraft, including rules relating to low altitude flights. The requirements in other countries vary greatly and may require permits and/or provide other restrictions to conducting flight operations in the country that may restrict our ability to perform SFD® surveys as freely as in Canada and the United States.

21 20-F for the year ended December 31, 2012

In Colombia SFD® surveys must comply with three requirements not encountered in Canada and the United States. These requirements are: customs obligations and bonds related to the importation and exportation of the aircraft into Colombia; obtaining permits from the local aviation authority; and obtaining permits from the Colombian Air Force. NXT has successfully operated in Colombia in accordance with these requirements.

With our experience in Canada, the United States, Colombia and other countries, we do not anticipate any unanticipated government controls or regulations that will prevent timely completion of SFD® surveys. However, we may encounter government restrictions in other countries that may impair or restrict our ability conduct surveys.

If we encounter government regulation and restrictions that impact or prevent us from conducting surveys in any country then we will not be able to earn revenue and this may potentially expose the company to forfeiture of performance bonds.

D. Property, plant and equipment

Oil and Gas Properties

The company has minor interests in a limited number of acreage holdings of undeveloped lands in the western Canadian sedimentary basin. These assets are not a material asset of the company and have been written down a nominal value in our financial statements. Additionally the company is entitled to receive royalty interests on production from certain lands which were previously surveyed by clients. Royalty revenue is not significant at this time but may increase in the future if these lands, on which NXT holds royalty interests, become developed and commence to produce significant volumes of hydrocarbons prior to the expiry of the landowners related mineral leases.

Facilities

The company’s head office is a 7,087 square foot leased office space located at Suite 1400, 505-3rd Street SW, in Calgary, Alberta, Canada. The original six year lease was entered into on November 1, 2006 and was to expire on October 31, 2012. In March, 2012 the lease was extended for an additional 2.5 year term expiring April 30, 2015. The monthly minimum lease payment (including the company's share of estimated building operating costs) is currently $26,138 to April 30, 2015.

22 20-F for the year ended December 31, 2012

Equipment

Our SFD® technology is comprised of three main components, detailed below, which we collectively refer to as our SFD® survey system. This system is generally stored at our Calgary office facility unless deployed during survey operations when this equipment would travel with the aircraft or be stored in a locked facility at the survey location when not in use. In addition, there is extensive Interpretation equipment located in Calgary. The main categories of equipment used by the company are:

· Stress Field Detector - the stress field detector, or SFD® including a unit which houses the SFD® sensors, is the principal component of our technology. SFD® sensors respond to changes in subsurface stress. These responses are transformed through a passive transducer into electronic digital signals. Airborne surveys are conducted with an array of 22 SFD® sensors, consisting of 6 primary, 8 secondary and 8 development sensors, allowing multiple SFD® signals responses at all points of a survey.  

· Data Acquisition System—used in conjunction with the SFD® sensor array on surveys, our data acquisition system is a compact, portable computer system which concurrently acquires the electronic digital signals from the SFD® sensor array and other pertinent client data, including the GPS location information of the data.  

· SFD® Signal Conditioning Unit - this self-contained unit contains electronic circuits for stabilizing and conditioning electronic signals. All sensor output is directly connected to this unit and after signal conditioning is completed, all output is forwarded to the computer system.  

· Interpretation Theatre - once returned to our home base, the SFD® data collected is processed and converted into a format that can be used by our interpretation staff using systems consisting of generally off-the-shelf computer equipment, high definition monitors, projectors and screens. This equipment is generally permanently set up at our Calgary office facility. A remote interpretation theater is available and may be deployed during survey operations and would be set up in a facility at the survey clients city.  

The company is not affected by any significant environmental concerns nor is there any planned significant capital additions contemplated.

	8,532,166	3,770,134	4,887,114

Expenses for the years ended December 31, 2012, 2011 and 2010

SFD® survey costs – the increase in direct survey costs in 2012 is due the significant expansion in survey activity in 2012. As noted previously, surveys were completed in a total of four countries in 2012, whereas both 2011 and 2010 reflected a single, small scale survey. Survey costs include aircraft charter, fuel, and related permits and logistics, plus local travel and accommodations incurred. Survey costs as a percentage of revenue is not directly comparable each year, as costs can be a function of non-controllable factors such as weather and permitting delays, and if the project was subject to sales commissions or local sales taxes. For example, survey costs includes sales commissions of US$ 696,977 for projects completed in 2012 (and $nil in 2011, and $13,662 in 2010).

Also, there will be inherent cost differences between operating in Colombia or elsewhere in Latin America as compared with Canada and the United States. Costs incurred to mobilize and demobilize the survey aircraft and crews will vary, depending on the distance travelled to the survey location. In addition, in some foreign countries NXT may incur many delays related to obtaining permits and approvals not required in Canada that can result in surveys taking several additional weeks to fly them. These delays result in additional aircraft, crew and accommodation costs.

General and administrative (“G&A”) – G&A can vary year to year due to changes in administrative and interpretation and operations staffing headcounts required to service the expected levels of contract activity. Survey costs do not reflect a charge (other than out of country per diem allowances) for interpretation or operations staff payroll and benefits, which is included in G&A.

G&A increased significantly in 2012, rising by $1,290,363 or 40%, due largely to the increase in survey activity, and the requirement to increase the company’s headcount of operations and administration staff. In addition, with an increase in financial resources, the company expanded its efforts in the areas of investor relations and market awareness as well as client prospecting.

25 20-F for the year ended December 31, 2012

For 2011, the $460,663 net decrease in G&A costs from 2010 to 2011 was primarily due to a reduced number of staff in 2011, and a high level of start-up costs which were incurred in 2010 in establishing a branch office presence in Bogota, to service the Colombia and Latin America markets.

For 2010, G&A increased marginally, rising by 3% or $109,727 to $3,678,806 compared to $3,569,079 for 2009. The increase was partly due to a higher level of sales and marketing activities.

G&A is a major component of NXT's total expenses, and includes the following categories of costs:

For the year ended December 31	2012	2011	2010
Salaries, benefits and consulting charges	$ 2,397,859	$ 1,725,237	$ 1,840,743
Board, professional fees, and public company costs	779,346	560,416	496,299
Premises and administrative overhead	632,058	520,689	589,609
Business development	464,262	274,454	240,759
Colombia office	234,981	195,679	511,396
Other	-	(58,332)	-
Total G&A	4,508,506	3,218,143	3,678,806

Stock Based Compensation Expense (“SBCE”) – this expense can vary widely each year, as it is a function of many factors, such as the number of stock options granted in a year, the length of the related vesting period of the options, and inputs used in the Black-Scholes option valuation model, such as the trailing volatility in the company’s share price.

The high SBCE in 2010 compared to 2011, for example, was primarily due to recognizing a significant expense total in Q4-2010 upon a re-pricing of all outstanding stock options to a revised price of Cdn $0.63 per share.

Amortization expense – most of our capital investment in property and equipment is in computer hardware, which is amortized on a 30% declining balance basis, such that amortization is high in the initial year of capital investment. In the last 3 years, capital spending has been minimal, resulting in a lower cost base subject to amortization in 2012, and thus a reduced level of amortization expense.

Other Expense (Income)

For the year ended December 31	2012	2011	2010
Interest income, net	$ 2,744	$ (16,353)	$ (9,923)
Loss (gain) on foreign exchange	14,686	(28,209)	16,509
Oil and natural gas operations, net	15,273	3,679	665
Other expense	51,700	-	1,074
Change in fair value of derivative instruments	(168,143)	-	-
	(83,740)	(40,883)	8,325

Interest income - Interest income, generated by short term investments, is offset by interest expense incurred on such items as capital lease obligations for office equipment.

Loss (gain) on foreign exchange – gains and losses on foreign exchange are caused by changes in the relative exchange values of the US dollar, Canadian dollar and Colombian peso ("COP"). For example, when the Canadian dollar trades higher relative to the US$ or COP, cash held in US$ or COP will decline in value and this decline will be reflected as a foreign exchange loss in the period. NXT normally holds its cash and short-term investments in Canadian dollars to reduce the effect of market volatility; however, we currently are contractually obligated to hold certain restricted cash funds in US$ instruments to support performance bond commitments in certain foreign countries.

26 20-F for the year ended December 31, 2012

Oil and natural gas operations, net – since prior to 2009, the company has had minor interests in some oil and gas properties in Canada. This category includes minor amounts of revenues from gross over-riding royalties (“GORR”) on two producing properties, net of costs related to these and other properties.

NXT holds GORR entitlements on potential future production on much of the land where we have conducted past surveys for clients in Canada, such as in the Horn River shale gas basin in British Columbia. There is no certainty, however, that wells on these lands will become placed on production, or that future royalty revenues will be earned from these entitlements. No asset value has been recorded in the financial statements for these GORRs.

In addition, the company has continuing asset abandonment and reclamation obligations (“ARO”) related to its minority working interests in various oil and gas wells in which it had a historical participation prior to 2005. At December 31, 2012, the ARO is estimated to be $61,813 (December 31, 2011 – $57,953), based on obligations which are estimated to be settled in the next three years. The net present value of the ARO is estimated based on inflation of 3.4% and discounted using a credit-adjusted risk-free interest rate of 10%.

Other expense – other expense of $51,700 in 2012 includes primarily costs related to intellectual property filings and new R&D activity related to the SFD® technology.

Change in fair value of derivative instruments - the derivative instruments relate to the estimated fair value of the common share purchase warrants (which have a US$ exercise price) which were issued in the company’s private placement equity financing in early 2012. As these warrants are denominated in a currency other than the Company's Canadian $ functional currency, they are classified as "derivative instruments" under US GAAP, and are recorded on a fair value basis (a total of $241,000 as at December 31, 2012). This balance is adjusted to its estimated fair value at each period end (until expiry of the warrants in March and May, 2014), based on the number of warrants outstanding. These derivative instruments are classified as a liability balance, but do not require any ongoing outlay of cash.

NXT currently has no other outstanding financial instruments, such as foreign currency hedges.

Summary of Quarterly Results (Unaudited)

A summary of operating results for each of the trailing 8 quarters (including a comparison to each respective prior quarter) follows. The extent of the profit or loss each quarter is mainly due to the timing and the number of survey contracts that are underway, and variances in such non-cash items as SBCE, which can occasionally be a significant expense in any given quarter. In addition, in Q3-12, NXT commenced to recognize significant adjustments to the fair value of "derivative instruments", which include US$ denominated warrants to purchase NXT common shares.

Q4-12 to Q3-12 comparison - NXT had survey revenue of $5,727,392 ($nil in Q3-12), SBCE of $59,000 ($78,000 in Q3-12) and survey costs of $1,277,768 ($24,170 net recovery in Q3-12). In addition, a non-cash income amount of $336,000 ($158,000 expense in Q3-12) was recognized in relation to adjusting the fair value of derivative instruments and income taxes of $216,807 ($nil in Q3-12) were recognized. Due primarily to the completion of the large Mexico contract in Q4-12, a net profit of $3,087,323 arose, as compared to a net loss of $1,393,183 for Q3-12.

Q3-12 to Q2-12 comparison - NXT had survey revenue of $nil ($2,394,863 in Q2-12), SBCE of $78,000 ($61,000 in Q2-12) and a survey cost recovery of $24,170 (expense of $1,205,654 in Q2-12). In addition, a non-cash expense of $158,000 was recognized in relation to adjusting the fair value of derivative instruments. As no contract revenue was recognized in the Q3-12 period, a net loss of $1,393,183 arose, as compared to a profit of $30,660 for Q2-12.

Q2-12 to Q1-12 comparison - NXT had survey revenue of $2,394,863 ($2,815,320 in Q1-12), SBCE of $61,000 ($67,000 in Q1-12) and survey costs of $1,205,654 ($1,174,393 in Q1-12). With the completion of the Argentina and Guatemala surveys in Q2-12, NXT recognized a profit of $30,660 as compared to a net profit of $337,928 for Q1-12, which reflected the completion of the Colombia survey.

Q1-12 to Q4-11 comparison - NXT had survey revenue of $2,815,320 ($nil in Q4-11), SBCE of $67,000 ($50,015 in Q4-11) and survey costs of $1,174,393 ($nil in Q4-11). Due to the completion of the large Colombia survey in Q1-12, NXT recognized a net profit of $337,928 for Q1-12 as compared to a loss of $1,072,560 for Q4-11.

Q4-11 to Q3-11 comparison - NXT had survey revenue of $nil ($nil in Q3-11), SBCE of $50,015 ($246,000 in Q3-11) and $nil survey costs ($nil in Q3-11).

Q3-11 to Q2-11 comparison - NXT had survey revenue of $nil ($144,650 in Q2-11), SBCE of $246,000 ($18,843 in Q2-11) and $nil survey costs ($43,990 in Q2-11). The high total SBCE recorded in Q3-11 was due to the large number of stock options granted in Q3-11, and the fact that 42% of such had immediate vesting.

Q2-11 to Q1-11 comparison - NXT had survey revenue of $144,650 ($nil in Q1-11), SBCE of $18,843 ($29,942 in Q1-11) and survey costs of $43,990 ($nil in Q1-11).

Q1-11 to Q4-10 comparison - NXT recognized $nil survey revenue ($nil in Q4-10) and SBCE of $29,942 ($404,053 in Q4-10). The $374,111 decrease in SBCE from Q4-10 is attributed to nearly all stock options held by contractors becoming fully vested in Q1-11 and the large expense that was recognized in Q4-10 upon re-pricing of stock options to $0.63 per share.

Q4-10 to Q3-10 comparison - NXT recognized $nil in survey revenue ($nil in Q3-10) and SBCE of $404,053 ($72,899 in Q3-10). The increase in SBCE was due to a one-time valuation adjustment that occurred when 2,113,204 stock options were re-priced in December 2010 to a new exercise price of $0.63 per share.

Q3-10 to Q2-10 comparison - in Q3-10 NXT had $nil survey revenue ($443,011 in Q2-10) and SBCE of $72,899 ($31,507 in Q2-10).

Q2-10 to Q1-10 comparison - in Q2-10 NXT recognized survey revenue of $443,011 ($nil for Q1-10), SBCE of $31,507 ($69,356 for Q1-10) and survey costs of $342,959 ($118,056 for Q1-10).

28 20-F for the year ended December 31, 2012

Q1-10 to Q4-09 comparison - in Q1-10 NXT had $nil survey revenue ($1,044,766 in Q4-09), SBCE of $69,356 ($187,343 for Q4-09) and $118,056 survey costs ($508,308 for Q4-09). The survey costs in Q1-10 were for non-revenue projects.

B. Liquidity and capital resources

The company’s sources of liquidity include cash flow from operations, and the use of equity financings as needed. At present, there are no bank debt facilities available to the company. The company expects that its current working capital is sufficient to meet its present requirements.

The company does not presently have any legal or economic restrictions that would affect the ability of any subsidiaries to transfer funds to the company. As of the last fiscal year end, and the present date, the company does not have any material outstanding commitments for capital expenditures that require funding.

NXT's cash and cash equivalents plus short-term investments at the end of Q4-12 was $5,107,594. This excludes a total of $433,369 which is classified on the Balance Sheet as restricted cash, which is required primarily as security for contract performance bonds. The net increase in restricted cash in 2012 is related to security which was required to be posted for letters of credit (often for a term of 12 to 15 months) that were issued to undertake the Guatemala survey in Q2-12, and to undertake the survey in Pakistan, which commenced in Q4-12. All of these funds are scheduled to be released back to NXT when the related letters of credit expire in 2013.

Significant progress was made by NXT in 2011 and 2012 in securing new revenue contracts and expanding our working capital. NXT's ability to continue as a going concern, however, remains dependent upon our success in being able to continue to attract new client projects and expand the revenue base to a level sufficient to far exceed G&A expenses, and generate excess net cash flow from operations. Equity financings have been used on a limited basis in recent years to supplement working capital as the Company has changed its strategy to focus its efforts on the international oil and gas exploration markets. Private placement financings totaling US $3.2 million (US $3.0 million net of finder’s fees incurred) were conducted in early 2012 (as further detailed below) to enhance NXT's financial strength and fund its expansion plans. Risks related to having sufficient ongoing working capital to execute survey project contracts are mitigated through our normal practice of obtaining progress payments from clients throughout the course of the projects.

We are encouraged that acceptance of NXT's technology in the oil & gas exploration industry is expanding - customer success in using SFD® to reduce their exploration time, cost, and risk is growing, and starting to yield repeat business. In 2011 NXT secured two significant new contracts to conduct SFD® survey projects in Colombia and Guatemala (total of US $4.6 million, of which US $2.9 million was completed in Q1-12 and US $0.7 million was completed in Q2-12) and in Argentina (US $1.65 million, completed in Q2-12). In Q3-12, NXT commenced its largest project ever, a US $5.8 million survey project in Mexico, which was completed and delivered to PEMEX in only 4 months.

In addition, in December 2012 NXT commenced a US $2.7 million (contract value prior to 15% in-country with-holding taxes) survey project in Pakistan for a major National Oil Company. This contract was originally awarded in late 2010, and took an extensive period of time to obtain all necessary government approvals and flight permits. Data acquisition for the project was efficiently completed by mid January 2013, and the SFD® survey recommendations report was then delivered to our client in March 2013.

In order to enhance financial resources, and give flexibility to expand and conduct new contracts, in Q1-12 NXT commenced a non-brokered private placement financing (the "Financing") of “Units” (at $0.75 per Unit), with each Unit consisting of one common share plus one common share purchase warrant.

A total of US $3.2 million (US $3.0 million net of finder’s fees) was raised through four separate closings which occurred from March 7 through May 4, 2012. This resulted in the issue of 4,258,005 common shares and a total of 4,502,821 warrants (which have an exercise price of US $1.20 and a two year term to expiry in 2014) to purchase NXT common shares.

29 20-F for the year ended December 31, 2012

NXT has no secured debt, and following the private placement financing and completion of several survey revenue contracts in 2012, net working capital increased significantly in 2012 as follows:

	December 31,	December 31,	net change
	2012	2011	in 2012
Current assets (current liabilities):
Cash and short term investments	$ 5,107,594	$ 1,518,946	$ 3,588,648
Restricted cash	433,369	-	433,369
Accounts receivable	472,308	122,231	350,077
Prepaid expenses and other	140,649	43,105	97,544
Accounts payable and accrued liabilities	(1,623,724)	(1,347,925)	(275,799)
Current portion of capital lease obligation	-	(8,591)	8,591
Net working capital before the undernoted items	4,530,196	327,766	4,202,430
Additional asset (liability) amounts:
Work-in-progress	976,463	1,112,210	(135,747)
Deferred revenue	(317,103)	(1,776,496)	1,459,393
Fair value of derivative instruments	(241,000)	-	(241,000)
	418,360	(664,286)	1,082,646
Net total	4,948,556	(336,520)	5,285,076

The derivative instruments relate to the estimated fair value of the common share purchase warrants (which have a US$ exercise price) which were issued in the private placement financings in March and May 2012. This balance is adjusted to its estimated fair value at each period end (until expiry of the warrants in March and May, 2014), based on the number of warrants outstanding. These derivative instruments are classified as a liability, but do not require any ongoing outlay of cash.

NXT applies the "completed contract" method of revenue recognition - revenues and related project costs are deferred until the period in which the survey contract is completed. Deferred revenue (a current liability) represents progress billing amounts that are to be recognized in revenue in future periods. Similarly, work-in-progress ("WIP", a current asset) relates to deferred survey costs which will be expensed in future periods upon completion of the related contracts. The WIP balance at December 31, 2012 relates to the Pakistan survey which commenced in December, and was completed in March, 2013.

Also, deferred revenue represents only the portion of progress billings that were issued to the quarter end for the uncompleted contracts. At December 31, 2012, the deferred revenue balance relates almost entirely to the Pakistan project.

The comparative totals for WIP and deferred revenue balances as at December 31, 2011 were related primarily to the four block Colombia survey project, which commenced in late 2011, and was completed in January 2012.

The increased total of accounts payable and accrued liabilities at Q4-12 as compared to Q4-11 is largely due to the timing of survey projects, and the related timing of payment of the related costs incurred. Most of the costs related to the Mexico survey were paid by December 31, 2012, whereas most costs related to the Pakistan survey were paid in Q1-13. The total at Q4-12 also includes a slightly higher total for accrued bonuses, wages and director fees payable as compared to Q4-11.

30 20-F for the year ended December 31, 2012

The following table, and the narrative below, summarizes the company’s net cash flows for the last three fiscal years:

For the year ended December 31	2012	2011	2010
Cash provided by (used in):
Operating activities	792,992	(1,756,515)	(2,692,776)
Financing activities	3,203,443	1,916,481	45,837
Investing activities	(452,787)	884,397	(1,062,623)

Cash, end of the year	5,052,594	1,508,946	464,583

Operating Activities

Net cash flow from operating activities listed above is a function of net income (loss) for the year, an add back of the net non-cash revenue and expense items (such as SBCE), and the net change in year-end working capital items (ex. a net decrease in working capital in the year gives rise to a source of cash), with these components each year as follows:

For the year ended December 31	2012	2011	2010
Net income (loss) for the year	2,062,728	(3,584,601)	(4,452,428)
Add back net non-cash items	225,732	508,787	746,144
	2,288,460	(3,075,814)	(3,706,284)
Change in non-cash working capital balances	(1,495,468)	1,319,299	1,013,508
Total cash provided by (used in) in operations	792,992	(1,756,515)	(2,692,776)

Financing Activities

2012 – the net cash source of $3,203,443 reflects $2,886,024 net proceeds from a private placement equity financing which closed in early 2012, plus $326,010 from the exercise of warrants which were issued in the February 2011 financing, $47,250 proceeds from the exercise of stock options, less a $8,591 reduction in a capital lease obligation.

In order to enhance our financial position, in 2012 the company completed a large non-brokered private placement of units (the “Units”) for aggregate proceeds of US $3,193,505 (US $3,009,893 net of related finder’s fees paid) including $40,000 received from two officers of the company.

Each Unit was issued at a price of US $0.75 and consisted of one common share of the company and one warrant (the “Warrants”). Each Warrant entitles the holder to acquire an additional NXT common share at a price of US $1.20 for a two year period to expiry (which ranges from March 8 to May 4, 2014). The expiry date may become accelerated at the discretion of the company if the shares trade on the US OTCBB at a price greater than US $1.50 for 20 consecutive trading days. The company also issued a total of 244,816 finder's warrants (as part of finder’s fees paid) with the same terms as the Warrants noted above.

2011 – the net cash source of $1,916,481 reflects $1,487,827 net proceeds from a private placement equity financing which closed in February 2011, plus $420,000 from the exercise of warrants which were issued on that financing, $18,900 proceeds from the exercise of stock options, less a $10,246 reduction in the capital lease obligation.

2010 – the net cash source of $45,837 reflects $54,518 proceeds from the exercise of stock options, less capital lease repayments of $8,681.

31 20-F for the year ended December 31, 2012

Investing Activities

2012 - the overall net cash use of $452,787 reflects a $45,000 funds outflow arising from an increase in short-term investments, $359,234 cash used to increase restricted cash balances, and $48,553 invested in purchases of property and equipment. Restricted cash balances relate primarily to balances used as security for bank letters of credit, which are often required to be issued to foreign survey clients as performance guarantees.

2011 - the overall net cash source of $884,397 reflects a $895,651 funds inflow arising from the net redemption of short-term investments (which was primarily used to fund ongoing operating expenses, and a temporary increase in restricted cash balances in the first half of 2011) plus a $27,721 net decrease in restricted cash balances, less $38,975 invested in purchases of property and equipment.

2010 - $905,651 was invested in short-term investments and $55,516 was invested in capital assets.

C. Research and development, patents and licenses, etc.

There was no separate research and development (“R&D”) expense reported in 2012, 2011 and 2010. In these three years any expenditures related to R&D were not significant and were included within general and administrative expense.

D. Trend information

The company has historically conducted a limited number of service contracts each year, the dollar value and timing of securing and ultimate delivery of which are subject to numerous external factors. As at April 16, 2013 the company currently does not have any committed “backlog” or order book of contracts to be performed.

Summary of Stock Options and Stock Appreciation Rights Granted To Executive Officers and Directors

All stock options have been granted pursuant to the Option Plan (the “Plan”) of the company or predecessor plans with substantially the same terms. The Plan is approved and ratified by shareholders annually at the company’s annual general meeting (“AGM”). The Plan, as was re-approved and ratified at the company’s last AGM held on November 27, 2012 is incorporated by reference into this Form 20-F as Exhibit No. 2.18. Pursuant to this Plan, all option grants must be approved by the board of directors of the company. Stock options may be granted to the directors, officers and employees of NXT and to consultants retained by the company. The aggregate number of common shares reserved for issuance under this Plan, and any other plan of the Corporation, shall not, at the time of the stock option grant, exceed ten percent of the total number of issued and outstanding shares (calculated on a non-diluted basis) unless the company receives the permission of the stock exchange or exchanges on which the shares are then listed to exceed such threshold. No option shall be exercisable for a period exceeding five (5) years from the date the option is granted unless the company receives the permission of the stock exchange or exchanges on which the shares are then listed and as specifically provided by the board and as permitted under the rules of any stock exchange or exchanges on which the shares are then listed, and in any event, no option shall be exercisable for a period exceeding ten (10) years from the date the option is granted. Options are generally issued with a three year vesting period wherein entitlement to exercise one third of the options granted shall vest at the end of each of the first three years following the grant date. The exercise price for an option grant is set at the last trade price on the date of grant or some higher price at the discretion of the board.

The following stock options were granted to our executive officers and directors in the three prior fiscal years ended December 31, 2012, 2011, and 2010 and to date to April 16, 2013:

This re-pricing was approved by disinterested shareholders at the company’s AGM held on December 8, 2010 and subsequently approved by the TSX Venture Exchange. All other existing terms of these options remained unchanged.

The following table sets forth information regarding outstanding stock options which have been granted to our directors and officers as of April 16, 2013.

ITEM 7. MAJOR SHAREHOLDERS AND RELATED PARTY TRANSACTIONS

A. Major shareholders

The following table sets forth information concerning the beneficial ownership of our common shares as of April 16, 2013 by persons who beneficially own 5% or more of the outstanding common shares of the company, each person who is a director of our company, each executive officer named in this Form 20-F, each individual referenced in Item 6.D above and all directors and executive officers as a group. For the purposes of this Form 20-F, a person is considered to be a “beneficial owner” of common shares in the company if that person has, or shares with another person, the power to direct the vote or disposition of the common shares or to receive the economic benefit of ownership of the common shares. A person is also deemed to be a beneficial owner of a common share if that person has the right to acquire the share within 60 days by option or other agreement (whether or not, in the case of a stock option, the current market price of the underlying common share is below the stock option exercise price). Therefore, the table below also reflects, for each such beneficial owner, the number of options, warrants and preferred shares either exercisable or convertible into common shares within 60 days of April 16, 2013 that are owned by each beneficial owner, but, in determining the percentage ownership and general voting power of such person, does not assume the exercise of options or the conversion of securities owned by any other person. We believe the beneficial owners of common shares listed below, based on information they furnished, have sole voting and investment power over the number of shares listed opposite their names. The percentage of beneficial ownership is based on 39,554,959 common shares issued and outstanding as of April 16, 2013. This total of 39,554,959 excludes all outstanding options and warrants that are exercisable within 60 days of April 16, 2013 (see also footnote 5 below).

A person is qualified to be or stand for election as a director provided such person is at least 18 years of age, is not bankrupt and is not mentally incapacitated pursuant to applicable mental health legislation of the Province of Alberta or pursuant to an order of the courts of the Province of Alberta. There is no provision in NXT’s Articles or By-Laws relating to the retirement or non-retirement of directors under an age limit requirement. There is also no requirement in NXT’s Articles or By-Laws for a director to hold securities of NXT.

47 20-F for the year ended December 31, 2012

Pursuant to the ABCA, a director or officer shall not be disqualified by his office, or be required to vacate his office, by reason only that he is a party to, or is a director or officer or has a material interest in any person who is a party to, a material contract or proposed material contract with NXT or subsidiary thereof. Such a director or officer shall, however, disclose the nature and extent of his interest in the contract at the time and in the manner provided by the ABCA. Any such contract or proposed contract shall be referred to the board of directors of NXT or shareholders for approval even if such contract is one that in the ordinary course of NXT's business would not require approval by the board or shareholders. Subject to the provisions of the ABCA, a director shall not by reason only of his office be accountable to NXT or to its shareholders for any profit or gain realized from such a contract or transaction, and such contract or transaction shall not be void or voidable by reason only of the director's interest therein, provided that the required declaration and disclosure of interest is properly made, the contract or transaction is approved by the directors or shareholders, and it is fair and reasonable to NXT at the time it was approved and, if required by the ABCA, the director refrains from voting as a director on the contract or transaction and absents himself from the director's meeting at which the contract is authorized or approved by the directors, except attendance for the purpose of being counted in the quorum.

Rights Attached to Common Shares

The holders of the common shares are entitled to dividends as and when declared by the directors of NXT, to one vote per share at meetings of shareholders of NXT, and upon liquidation, subject to the rights of the holders of preferred shares, are entitled to share rateably with the holders of the common shares in all distributions of assets of NXT.

Rights Attached to Preferred Shares

Preferred shares may be issued from time to time in one or more series. The board of directors of NXT is expressly authorized to provide by resolution duly adopted prior to issuance, for the creation of each such series and to fix the designation, rights, privileges, restrictions and conditions attached to the shares of each such series, including the rate or amount of dividends or the method of calculating dividends, the dates of payment of dividends, the redemption, purchase and/or conversion prices and terms and conditions of redemption, purchase and/or conversion, and any sinking fund or other provisions.

The preferred shares of each series shall, with respect to the payment of dividends and the distribution of assets or return of capital in the event of liquidation, dissolution or winding-up of NXT, whether voluntary or involuntary, or any other return of capital or distribution of the assets of NXT among its shareholders for the purpose of winding up its affairs, rank on a parity with the preferred shares of every other series and be entitled to preference over the common shares and over any other shares of NXT, if any, ranking junior to the preferred shares. The preferred shares of any series may also be given other preferences, not inconsistent with the articles of continuance of NXT (the "Articles"), over the common shares and any other shares of NXT ranking junior to the preferred shares of a series as may be fixed by the board of directors of NXT.

If any cumulative dividends or amounts payable on the return of capital in respect of a series of preferred shares are not paid in full, all series of preferred shares shall participate rateably in respect of accumulated dividends and return of capital.

Unless the board of directors of NXT otherwise determine in the articles of amendment designating a series of preferred shares, the holder of each share of a series of preferred shares shall not, as such, be entitled to receive notice of or vote at any meeting of shareholders, except as otherwise specifically provided in the ABCA.

48 20-F for the year ended December 31, 2012

Rights Attached to Preferred Shares - Series 1

NXT is authorized to issue up to 10,000,000 preferred shares - Series 1. In 2006 10,000,000 preferred shares - Series 1 (the “Series 1 Shares”) were issued and are outstanding as at December 31, 2012, with the following material attributes:

Voting Rights

Subject to applicable law, the holders of the Series 1 Shares shall not be entitled to any voting rights or to receive notice of or to attend any meeting of the shareholders of NXT.

Dividends

The holders of the Series 1 Shares shall not be entitled to receive any dividends on the Series 1 Shares.

Conversion

The Series 1 Shares are convertible as follows:

(a) as to 20% of the total issued Series 1 Shares on December 31, 2006;

(b) as to an additional 20% of the total issued Series 1 Shares on the date that gross cumulative
aggregate revenues of NXT reach $50 million;

(c) as to an additional 20% of the total issued Series 1 Shares on the date that gross cumulative
aggregate revenues of NXT reach $100 million;

(d) as to an additional 20% of the total issued Series 1 Shares on the date that gross cumulative
aggregate revenues of NXT reach $250 million; and

(e) as to an additional 20% of the total issued Series 1 Shares on the date that gross cumulative
aggregate revenues of NXT reach $500 million.

Upon a change of control of NXT, as to the amount of Series 1 Shares not yet expired, converted or redeemed, as the case may be, in accordance with the terms thereof, the Series 1 Shares shall become convertible as follows:

(a) as to all of the total issued Series 1 Shares if the sale price per common share paid by an acquirer on transaction constituting a change of control of NXT or the per share amount received by the holders of common shares on a liquidation of the assets of NXT or the winding-up or re-arrangement of NXT's business is equal to or exceeds $10;

(b) as to 60% of the total issued Series 1 Shares if the sale price per common share paid by an acquirer on a transaction constituting a change of control of NXT or the per share amount received by the holders of common shares on a liquidation of the assets of NXT or the winding-up or re-arrangement of NXT's business is equal to or exceeds $5; and

(c) as to 20% of the total issued Series 1 Shares regardless of the sale price per common share paid by an acquirer on transaction constituting a change of control of NXT or the per share amount received by the holders of common shares on a liquidation of the assets of NXT or the winding-up or re-arrangement of NXT's business.

The Series 1 Shares specified above held by the holder shall be convertible at the option of the holder, subject to the terms and provisions hereof, into common shares at the rate of one common share per each Series 1 Share, without payment of any additional consideration.

Upon a change of control, a holder shall be entitled to convert, in full or in part, the Series 1 Shares specified above, until the expiration of ninety (90) days after the date on which the holder of the Series 1 Shares gives or receives notice that such holder will no longer be providing services to NXT, or the date on which such holder is terminated by NXT.

The conversion of Series 1 Shares into common shares shall be evidenced by the holder delivering at any time during usual business hours at the head office of NXT:

49 20-F for the year ended December 31, 2012

(a) written notice, signed by the holder, specifying the number of Series 1 Shares to be converted; and

(b) the certificate or certificates representing the Series 1 Shares to be converted.

The rights of the holder of such Series 1 Shares, as the holder thereof, shall cease at the date of conversion into common shares and the person or persons entitled to receive common shares upon such conversion shall be treated for all purposes as having become the holder or holders of record of such common shares at such time.

The registered holder of any common shares resulting from any such conversion shall be entitled to rank equally with the registered holders of all other common shares in respect of all dividends declared payable to holders of common shares of record on any date after the date of conversion into common shares.

The board of directors shall have the right at any time to cause the conversion of all or a portion of the Series 1 Shares in the discretion of the board.

NXT shall be entitled to make all tax withholdings, if any, as required by law, with respect to a conversion of Series 1 Shares for common shares.

Redemption

Subject to applicable law and subject to NXT's right to force the conversion of the Series 1 Shares, NXT shall be required to redeem and shall be deemed to have redeemed all of the Series 1 Shares held by the holder on December 31, 2015 at a price of $0.001 per Series 1 Share (the “Redemption Price”).

On any redemption of Series 1 Shares, NXT shall give a notice in writing of its redemption of the Series 1 Shares (the "Redemption Notice") to each person who at the date of giving of such notice is a registered holder of Series 1 Shares to be redeemed, setting out the date the Series 1 Shares are to be redeemed or are deemed to have been redeemed (the "Redemption Date") and the number of Series 1 Shares which are to be redeemed or are deemed to have been redeemed.

Liquidation

The holders of Series 1 Shares shall not be entitled in the event of any liquidation, dissolution or winding up of NXT, whether voluntary or involuntary, or any other distribution of the assets of NXT among its shareholders for the purpose of winding up its affairs to any return of capital other than payment of the Redemption Price for each Series 1 Share in preference to the holders of common shares.

After payment to the holders of the Series 1 Shares of the amounts so payable to them, the holders of Series 1 Shares shall not be entitled to share in any further distribution of the property or assets of NXT.

Alteration of the Rights of Shareholders

Under the ABCA, any substantive change to the Articles (including, but not limited to, change of any maximum number of shares that NXT is authorized to issue, creation of new classes of shares, add, change or remove any rights, privileges, restrictions and conditions in respect of all or any of its shares, whether issued or unissued, change the shares of any class or series, whether issued or unissued, into a different number of shares of the same class or series or into the same or a different number of shares of other classes or series) or other fundamental changes to the capital structure of NXT, including a proposed amalgamation or continuance of NXT out of the jurisdiction, requires shareholder approval by not less than 2/3 of the votes cast by shareholders voting in person or by proxy at a shareholders’ meeting called for that purpose. In certain prescribed circumstances, holders of shares of a class or of a series are entitled to vote separately as a class or series on a proposal to amend the Articles whether or not shares of a class or series otherwise carry the right to vote. The holders of a series of shares of a class are entitled to vote separately as a series only if the series is affected by an amendment in a manner different from other shares of the same class.

50 20-F for the year ended December 31, 2012

Meetings of Shareholders

NXT’s By-Laws provide that the board of directors shall call an annual meeting of shareholders to be held not later than eighteen months after the date of incorporation and subsequently, not later than fifteen months after holding the last preceding annual meeting. NXT’s By-Laws provide that the board of directors may at any time call a special meeting of shareholders. Only the registered holders of shares are entitled to receive notice of and vote at annual and special meetings of shareholders, except to the extent that:

(a) if a record date is fixed, the person transfers ownership of any of the person’s shares after the record date; or

(b) if no record date is fixed, the person transfers ownership of any of the person’s shares after the date on which the list of shareholders is prepared; and

(c) the transferee of those shares;

§ produces properly endorsed share certificates; or

§ otherwise establishes ownership of the shares; and

§ demands, not later than ten (10) days before the meeting, that the transferee’s name be included in the list before the meeting;

in which case the transferee is entitled to vote the shares.

The ABCA also permits the holders of not less than 5% of the issued voting securities of NXT to give notice to the board of directors requiring them to call and hold a meeting of NXT.

The only persons entitled to be present at a meeting of shareholders are:

(a) the shareholders entitled to vote at the meeting;

(b) the board of directors of NXT;

(c) the external auditor of NXT; and

(d) any others who, although not entitled or required under the provisions of the ABCA, any unanimous shareholder agreement, or the Articles or the By-Laws, are allowed to be present at the meeting.

Any other person may be admitted only on the invitation of the Chairperson of the meeting or with the consent of the meeting.

There are no restrictions in NXT’s Articles or By-Laws as to the number of shares that may be held by non-residents other than restrictions set out in the Investment Canada Act (the “ICA”) (Canada), as further described under Item 10.D – “Exchange Controls” below.

Change of Control

There are no specific provisions in the Articles or By-Laws of NXT that have the effect of delaying, deferring or preventing a change of control of NXT and that would operate only with respect to a merger, acquisition or corporate restructuring involving NXT (or any of its subsidiaries). Notwithstanding this, the board of directors, under the general powers conferred to it under NXT’s By-Laws, have the authority to approve and invoke a shareholders rights plan that will protect shareholders from unfair, abusive or coercive take-over strategies, including the acquisition or control of NXT by a bidder in a transaction or series of transactions that does not treat all shareholders equally or fairly or that does not afford all shareholders an equal opportunity to share in any premium paid upon an acquisition of control. NXT has not adopted such a plan.

Shareholder Ownership Disclosure

There are no provisions in NXT’s By-Laws regarding public disclosure of individual shareholdings.

51 20-F for the year ended December 31, 2012

C. Material contracts

Each material contract, other than contracts entered into in the ordinary course of business, to which the company has been a party, for the two years immediately preceding publication of this annual report, is listed as an exhibit to this annual report and is summarized elsewhere herein.

D. Exchange controls

There are no governmental laws, decrees or regulations in Canada relating to restrictions on the export or import of capital, or affecting the remittance of interest, dividends or other payments to non-residents. Dividends paid to U.S. residents, however, are subject to a 15% withholding tax or a 5% withholding tax for dividends if the shareholder is a corporation owning at least 10% of the outstanding voting shares of NXT pursuant to Article X of the reciprocal tax treaty between Canada and the U.S.

Except as provided in the ICA, which has provisions that restrict the holding of voting shares by non-Canadians, there are no limitations specific to the rights of non-Canadians to hold or vote the common shares under the laws of Canada or the Province of Alberta, or in the charter documents of NXT or its subsidiaries.

Management of NXT believes that the following summary fairly describes those provisions of the ICA pertinent to an investment in NXT by a person who is not a Canadian resident (a “non-Canadian”).

The ICA requires a non-Canadian making an investment which would result in the acquisition of control of a Canadian business (i.e. the gross value of the assets of which exceed a certain monetary threshold) to identify, notify, or file an application for review with the Investment Review Division of Industry Canada (“IRD”).

The notification procedure involves a brief statement of information about the investment on a prescribed form which is required to be filed with the IRD by the investor at any time up to 30 days following implementation of the investment. It is intended that investments requiring only notification will proceed without government intervention unless the investment is in a specific type of business activity related to Canada’s cultural heritage and national identity.

If an investment is reviewable under the ICA, an application for review in the form prescribed is normally required to be filed with the IRD prior to the investment taking place and the investment may not be implemented until the review has been completed and the Minister of Industry Canada (the “Minister”) (the Minister responsible for Investment Canada) is satisfied that the investment is likely to be of net benefit to Canada. The Minister has up to 75 days to make this determination. If the Minister is not satisfied that the investment is likely to be of net benefit to Canada, the non-Canadian must not implement the investment or, if the investment has been implemented, may be required to divest himself of control of the business that is the subject of the investment.

The following investments by non-Canadians are subject to notification under the ICA:

1. An investment to establish a new Canadian business; and

2. An investment to acquire control of a Canadian business that is not reviewable pursuant to the Act.

The following investments by a non-Canadian are subject to review under the ICA:

1. An investment is reviewable if there is an acquisition of a Canadian business and the asset value of the Canadian business being acquired equals or exceeds the following thresholds:

(a) For non-World Trade Organization (“WTO”) investors, the threshold is $5 million for a direct acquisition and $50 million for an indirect acquisition; the $5 million threshold will apply however for an indirect acquisition if the asset value of the Canadian business being acquired exceeds 50% of the asset value of the global transaction;

52 20-F for the year ended December 31, 2012

(b) Except as specified in paragraph (c) below, a threshold is calculated annually for reviewable direct acquisitions by or from WTO investors. The threshold for 2012 was $330 million. Pursuant to Canada’s international commitments, indirect acquisitions by or from WTO investors are not reviewable;

(c) The limits set out in paragraph (a) apply to all investors for acquisitions of a Canadian business that:

(i)engages in the production of uranium and owns an interest in a producing uranium property in Canada;

(ii)provides any financial service;

(iii)provides any transportation services; or

(iv)is a cultural business.

Notwithstanding the above, any investment which is usually only notifiable, including the establishment of a new Canadian business, and which falls within a specific business activity, including the publication and distribution of books, magazines, newspapers, film or video recordings, audio or video music recordings, or music in print or machine-readable form may be reviewed if an Order-in-Council directing a review is made and a notice is sent to the investor within 21 days following the receipt of a certified complete notification.

Generally speaking, an acquisition is direct if it involves the acquisition of control of the Canadian business or of its direct or indirect Canadian parent and an acquisition is indirect if it involves the acquisition of control of a non-Canadian direct or indirect parent of an entity carrying on the Canadian business. No change of voting control will be deemed to have occurred if less than one-third of the voting control of a Canadian corporation is acquired by an investor.

A WTO investor, as defined in the ICA, includes an individual who is a national of a member country of the WTO or who has the right of permanent residence in relation to that WTO member, a government or government agency of a WTO investor-controlled corporation, a limited partnership, trust or joint venture that is neither WTO-investor controlled or Canadian controlled of which two-thirds of its board of directors, general partners or trustees, as the case may be, are any combination of Canadians and WTO investors.

The ICA exempts certain transactions from the notification and review provisions of ICA, including, among others, (a) an acquisition of voting shares if the acquisition were made in the ordinary course of that person’s business as a trader or dealer in securities; (b) an acquisition of control of the company in connection with the realization of a security interest granted for a loan or other financial assistance and not for any purpose related to the provisions of the ICA; (c) the acquisition of voting interests by any person in the ordinary course of a business carried on by that person that consists of providing, in Canada, venture capital on terms and conditions not inconsistent with such terms and conditions as may be fixed by the Minister; and (d) acquisition of control of the company by reason of an amalgamation, merger, consolidation or corporate reorganization, following which the ultimate direct or indirect control in fact of the company, through the ownership of voting interests, remains unchanged.

E. Taxation

Certain United States Federal Income Tax Considerations

The following is a general summary of certain material U.S. federal income tax considerations applicable to a U.S. Holder (as defined below) arising from and relating to the acquisition, ownership, and disposition of common shares of the company.

This summary is for general information purposes only and does not purport to be a complete analysis or listing of all potential U.S. federal income tax considerations that may apply to a U.S. Holder arising from and relating to the acquisition, ownership, and disposition of common shares. In addition, this summary does not take into account the individual facts and circumstances of any particular U.S. Holder that may affect the U.S. federal income tax consequences to such U.S. Holder, including specific tax consequences to a U.S. Holder under an applicable tax treaty. Except as specifically set forth below, this summary does not discuss applicable tax reporting requirements. Accordingly, this summary is not intended to be, and should not be construed as, legal or U.S. federal income tax advice with respect to any U.S. Holder. Each U.S. Holder should consult its own tax advisor regarding the U.S. federal, U.S. federal alternative minimum, U.S. federal estate and gift, U.S. state and local, and foreign tax consequences relating to the acquisition, ownership and disposition of common shares.

53 20-F for the year ended December 31, 2012

No legal opinion from U.S. legal counsel or ruling from the Internal Revenue Service (the “IRS”) has been requested, or will be obtained, regarding the U.S. federal income tax consequences of the acquisition, ownership, and disposition of common shares. This summary is not binding on the IRS, and the IRS is not precluded from taking a position that is different from, and contrary to, the positions taken in this summary. In addition, because the authorities on which this summary is based are subject to various interpretations, the IRS and the U.S. courts could disagree with one or more of the positions taken in this summary.

Scope of this Summary

Authorities

This summary is based on the Internal Revenue Code of 1986, as amended (the “Code”), Treasury Regulations (whether final, temporary, or proposed), published rulings of the IRS, published administrative positions of the IRS, U.S. court decisions, the Convention Between Canada and the United States of America with Respect to Taxes on Income and on Capital, signed September 26, 1980, as amended (the “Canada-U.S. Tax Convention”), and U.S. court decisions that are applicable and, in each case, as in effect and available, as of the date of this document. Any of the authorities on which this summary is based could be changed in a material and adverse manner at any time, and any such change could be applied on a retroactive or prospective basis which could affect the U.S. federal income tax considerations described in this summary. This summary does not discuss the potential effects, whether adverse or beneficial, of any proposed legislation that, if enacted, could be applied on a retroactive or prospective basis.

U.S. Holders

For purposes of this summary, the term "U.S. Holder" means a beneficial owner of common shares that is for U.S. federal income tax purposes:

· an individual who is a citizen or resident of the U.S.;

· a corporation (or other entity taxable as a corporation for U.S. federal income tax purposes) organized under the laws of the U.S., any state thereof or the District of Columbia;

· an estate whose income is subject to U.S. federal income taxation regardless of its source; or

a trust that (a) is subject to the primary supervision of a court within the U.S. and the control of one or more U.S. persons for all substantial decisions or (b) has a valid election in effect under applicable Treasury regulations to be treated as a U.S. person.

Non-U.S. Holders

For purposes of this summary, a “non-U.S. Holder” is a beneficial owner of common shares that is not a U.S. Holder. This summary does not address the U.S. federal income tax consequences to non-U.S. Holders arising from and relating to the acquisition, ownership, and disposition of common shares. Accordingly, a non-U.S. Holder should consult its own tax advisor regarding the U.S. federal, U.S. federal alternative minimum, U.S. federal estate and gift, U.S. state and local, and foreign tax consequences (including the potential application of and operation of any income tax treaties) relating to the acquisition, ownership, and disposition of common shares.

U.S. Holders Subject to Special U.S. Federal Income Tax Rules Not Addressed

This summary does not address the U.S. federal income tax considerations applicable to U.S. Holders that are subject to special provisions under the Code, including the following U.S. Holders: (a) U.S. Holders that are tax-exempt organizations, qualified retirement plans, individual retirement accounts, or other tax-deferred accounts; (b) U.S. Holders that are financial institutions, underwriters, insurance companies, real estate investment trusts, or regulated investment companies; (c) U.S. Holders that are dealers in securities or currencies or U.S. Holders that are traders in securities that elect to apply a mark-to-market accounting method; (d) U.S. Holders that have a “functional currency” other than the U.S. dollar; (e) U.S. Holders that own common shares as part of a straddle, hedging transaction, conversion transaction, constructive sale, or other arrangement involving more than one position; (f) U.S. Holders that acquired common shares in connection with the exercise of employee stock options or otherwise as compensation for services; (g) U.S. Holders that hold common shares other than as a capital asset within the meaning of Section 1221 of the Code (generally, property held for investment purposes); (h) partnerships and other pass-through entities (and investors in such partnerships and entities); or (i) U.S. Holders that own or have owned (directly, indirectly, or by attribution) 10% or more of the total combined voting power of the outstanding shares of the company. This summary also does not address the U.S. federal income tax considerations applicable to U.S. Holders who are: (a) U.S. expatriates or former long-term residents of the U.S.; (b) persons that have been, are, or will be a resident or deemed to be a resident in Canada for purposes of the Income Tax Act (Canada) (the “Tax Act”); (c) persons that use or hold, will use or hold, or that are or will be deemed to use or hold common shares in connection with carrying on a business in Canada; (d) persons whose common shares constitute “taxable Canadian property” under the Income Tax Act (Canada) (the “Tax Act”); or (e) persons that have a permanent establishment in Canada for the purposes of the Canada-U.S. Tax Convention. U.S. Holders that are subject to special provisions under the Code, including U.S. Holders described immediately above, should consult their own tax advisor regarding the U.S. federal, U.S. federal alternative minimum, U.S. federal estate and gift, U.S. state and local, and foreign tax consequences relating to the acquisition, ownership and disposition of common shares.

54 20-F for the year ended December 31, 2012

If an entity that is classified as a partnership (or pass-through entity) for U.S. federal income tax purposes holds common shares, the U.S. federal income tax consequences to such partnership and the partners of such partnership generally will depend on the activities of the partnership and the status of such partners. This summary does not discuss the U.S. federal tax consequences to partners of entities that are classified as partnerships. Partners of entities that are classified as partnerships for U.S. federal income tax purposes should consult their own tax advisor regarding the U.S. federal income tax consequences arising from and relating to the acquisition, ownership, and disposition of common shares.

Tax Consequences Not Addressed

This summary does not fully address all of the U.S. federal, U.S. federal alternative minimum, U.S. federal estate and gift, U.S. state and local, and foreign tax consequences to U.S. Holders related to the acquisition, ownership, and disposition of the company's common shares. Each U.S. Holder should consult its own tax advisor regarding the U.S. federal, U.S. federal alternative minimum, U.S. federal estate and gift, U.S. state and local, and foreign tax consequences of the acquisition, ownership, and disposition of common shares.

U.S. Federal Income Tax Consequences of the Acquisition, Ownership, and Disposition of Our Common Shares

The following discussion is subject to the rules described below under the heading “Passive Foreign Investment Company Rules.”

Distributions on Common Shares

A U.S. Holder that receives a distribution, including a constructive distribution, with respect to a common share will be required to include the amount of such distribution in gross income as a dividend (without reduction for any Canadian income tax withheld from such distribution) to the extent of the current or accumulated “earnings and profits” of the company, as computed for U.S. federal income tax purposes. A dividend generally will be taxed to a U.S. Holder at ordinary income tax rates. To the extent that a distribution exceeds the current and accumulated “earnings and profits” of the company, such distribution will be treated first as a tax-free return of capital to the extent of a U.S. Holder’s tax basis in the common shares and thereafter as gain from the sale or exchange of such common shares (see “Sale or Other Taxable Disposition of Common Shares” below). However, the company does not intend to maintain the calculations of earnings and profits in accordance with U.S. federal income tax principles, and each U.S. Holder should therefore assume that any distribution by the company with respect to the common shares will constitute ordinary dividend income. Dividends received on common shares generally will not be eligible for the “dividends received deduction.”

55 20-F for the year ended December 31, 2012

Subject to applicable limitations and provided that the company is eligible for the benefits of the Canada-U.S. Tax Convention, dividends paid by the company to non-corporate U.S. Holders, including individuals, generally will be eligible for the preferential tax rates applicable to long-term capital gains for dividends, provided certain holding period and other conditions are satisfied, including that the company not be classified as a PFIC (as defined below) in the tax year of distribution or in the preceding tax year. The dividend rules are complex, and each U.S. Holder should consult its own tax advisor regarding the application of such rules.

Sale or Other Taxable Disposition of Common Shares

A U.S. Holder will recognize gain or loss on the sale or other taxable disposition of common shares in an amount equal to the difference, if any, between (a) the amount of cash plus the fair market value of any property received and (b) such U.S. Holder’s tax basis in such common shares sold or otherwise disposed of. Any such gain or loss generally will be capital gain or loss, which will be long-term capital gain or loss if, at the time of the sale or other disposition, such common shares are held for more than one year.

Gain or loss recognized by a U.S. Holder on the sale or other taxable disposition of common shares generally will be treated as “U.S. source” for purposes of applying the U.S. foreign tax credit rules unless the gain is subject to tax in Canada and is sourced as “foreign source” under the Canada-U.S. Tax Convention and such U.S. Holder elects to treat such gain or loss as “foreign source.”

Preferential tax rates apply to long-term capital gains of a U.S. Holder that is an individual, estate, or trust. There are currently no preferential tax rates for long-term capital gains of a U.S. Holder that is a corporation. Deductions for capital losses are subject to significant limitations under the Code.

Additional Tax on Passive Income

Individuals, estates and certain trusts whose income exceeds certain thresholds will be required to pay a 3.8% Medicare surtax on "net investment income" including, among other things, dividends and net gain from disposition of property (other than property held in certain trades or businesses). U.S. Holders should consult with their own tax advisors regarding the effect, if any, of this tax on their ownership and disposition of common shares.

Receipt of Foreign Currency

The amount of any distribution paid in foreign currency to a U.S. Holder in connection with the ownership of common shares, or on the sale, exchange or other taxable disposition of common shares, generally will be equal to the U.S. dollar value of such foreign currency based on the exchange rate applicable on the date of receipt (regardless of whether such foreign currency is converted into U.S. dollars at that time). A U.S. Holder that receives foreign currency and converts such foreign currency into U.S. dollars at a conversion rate other than the rate in effect on the date of receipt may have a foreign currency exchange gain or loss, which generally would be treated as U.S. source ordinary income or loss. If the foreign currency received is not converted into U.S. dollars on the date of receipt, a U.S. Holder will have a basis in the foreign currency equal to its U.S. dollar value on the date of receipt. Any U.S. Holder who receives payment in foreign currency and engages in a subsequent conversion or other disposition of the foreign currency may have a foreign currency exchange gain or loss that would be treated as ordinary income or loss, and generally will be U.S. source income or loss for foreign tax credit purposes. Each U.S. Holder should consult its own U.S. tax advisor regarding the U.S. federal income tax consequences of receiving, owning, and disposing of foreign currency.

Foreign Tax Credit

A U.S. Holder who pays (whether directly or through withholding) Canadian income tax with respect to dividends paid on common shares generally will be entitled, at the election of such U.S. Holder, to receive either a deduction or a credit for such Canadian income tax paid. Generally, a credit will reduce a U.S. Holder’s U.S. federal income tax liability on a dollar-for-dollar basis, whereas a deduction will reduce a U.S. Holder’s income subject to U.S. federal income tax. This election is made on a year-by-year basis and applies to all foreign taxes paid (whether directly or through withholding) by a U.S. Holder during a year.

Complex limitations apply to the foreign tax credit, including the general limitation that the credit cannot exceed the proportionate share of a U.S. Holder’s U.S. federal income tax liability that such U.S. Holder’s “foreign source” taxable income bears to such U.S. Holder’s worldwide taxable income. In applying this limitation, a U.S. Holder’s various items of income and deduction must be classified, under complex rules, as either “foreign source” or “U.S. source”. Generally, dividends paid by a foreign corporation should be treated as foreign source for this purpose, and gains recognized on the sale of stock of a foreign corporation by a U.S. Holder should be treated as U.S. source for this purpose, except as otherwise provided in an applicable income tax treaty, and if an election is properly made under the Code. However, the amount of a distribution with respect to the common shares that is treated as a “dividend” may be lower for U.S. federal income tax purposes than it is for Canadian federal income tax purposes, resulting in a reduced foreign tax credit allowance to a U.S. Holder. In addition, this limitation is calculated separately with respect to specific categories of income. Dividends paid by the company generally will constitute “foreign source” income and generally will be categorized as “passive income.”

The foreign tax credit rules are complex, and each U.S. Holder should consult its own tax advisor regarding the foreign tax credit rules.

Information Reporting; Backup Withholding Tax for Certain Payments

Under U.S. federal income tax law and regulations, certain categories of U.S. Holders must file information returns with respect to their investment in, or involvement in, a foreign corporation. For example, recently enacted legislation generally imposes new U.S. return disclosure obligations (and related penalties) on U.S. Holders that hold certain specified foreign financial assets in excess of certain threshold amounts. The definition of specified foreign financial assets includes not only financial accounts maintained in foreign financial institutions, but also, unless held in accounts maintained by a financial institution, any stock or security issued by a non-U.S. person, any financial instrument or contract held for investment that has an issuer or counterparty other than a U.S. person and any interest in a foreign entity. U. S. Holders may be subject to these reporting requirements unless their common shares are held in an account at certain financial institutions. Penalties for failure to file certain of these information returns are substantial. U.S. Holders of common shares should consult with their own tax advisors regarding the requirements of filing information returns, including the requirements to file IRS Form 8938.

Payments made within the U.S., or by a U.S. payor or U.S. middleman, of dividends on, and proceeds arising from the sale or other taxable disposition of, common shares generally will be subject to information reporting and backup withholding tax, at the current rate of 28%, if a U.S. Holder (a) fails to furnish such U.S. Holder’s correct U.S. taxpayer identification number (generally on Form W-9), (b) furnishes an incorrect U.S. taxpayer identification number, (c) is notified by the IRS that such U.S. Holder has previously failed to properly report items subject to backup withholding tax, or (d) fails to certify, under penalty of perjury, that such U.S. Holder has furnished its correct U.S. taxpayer identification number and that the IRS has not notified such U.S. Holder that it is subject to backup withholding tax. However, certain exempt persons, such as corporations, generally are excluded from these information reporting and backup withholding tax rules. Any amounts withheld under the U.S. backup withholding tax rules will be allowed as a credit against a U.S. Holder’s U.S. federal income tax liability, if any, or will be refunded, if such U.S. Holder furnishes required information to the IRS in a timely manner. Each U.S. Holder should consult its own tax advisor regarding the information reporting and backup withholding rules.

Passive Foreign Investment Company Rules

If the company were to constitute a PFIC (as defined below) for any year during a U.S. Holder’s holding period, then certain different and potentially adverse rules will effect the U.S. federal income tax consequences to a U.S. Holder resulting from the acquisition, ownership and disposition of common shares. In addition, in any year in which the company is classified as a PFIC, such holder would be required to file an annual report with the IRS containing such information as Treasury Regulations and/or other IRS guidelines may require.

57 20-F for the year ended December 31, 2012

The company generally will be a “passive foreign investment company” (“PFIC”) under Section 1297 of the Code if, for a tax year, (a) 75% or more of the gross income of the company for such tax year is passive income (the “income test”) or (b) 50% or more of the value of the assets held by the company either produce passive income or are held for the production of passive income, based on quarterly average of the fair market value of such assets (the “asset test”). “Gross income” generally includes sales revenues less the cost of goods sold, plus income from investments and from incidental or outside operations or sources, and “passive income” includes, for example, dividends, interest, certain rents and royalties, certain gains from the sale of stock and securities, and certain gains from commodities transactions. Active business gains arising from the sale of commodities generally are excluded from passive income if substantially all (85% or more) of a foreign corporation’s commodities are stock in trade or inventory, depreciable property used in a trade or business or supplies regularly used or consumed in the ordinary course of its trade or business, and certain other requirements are satisfied.

In addition, for purposes of the PFIC income test and asset test described above, if the company owns, directly or indirectly, 25% or more of the total value of the outstanding shares of another corporation, the company will be treated as if it (a) held a proportionate share of the assets of such other corporation and (b) received directly a proportionate share of the income of such other corporation. In addition, for purposes of the PFIC income test and asset test described above, “passive income” does not include any interest, dividends, rents, or royalties that are received or accrued by the company from a “related person” (as defined in Section 954(d)(3) of the Code), to the extent such items are properly allocable to the income of such related person that is not passive income.

Under certain attribution rules, if the company is a PFIC, U.S. Holders will be deemed to own their proportionate share of any subsidiary of the company which is also a PFIC (a ‘‘Subsidiary PFIC’’), and will be subject to U.S. federal income tax on (i) a distribution on the shares of a Subsidiary PFIC or (ii) a disposition of shares of a Subsidiary PFIC, both as if the holder directly held the shares of such Subsidiary PFIC.

The company does not believe that it was a PFIC during the tax year ending December 31, 2012. The determination of whether any corporation was, or will be, a PFIC for a tax year depends, in part, on the application of complex U.S. federal income tax rules, which are subject to differing interpretations. In addition, whether any corporation will be a PFIC for any tax year depends on the assets and income of such corporation over the course of each such tax year and, as a result, cannot be predicted with certainty as of the date of this document. Accordingly, there can be no assurance that the IRS will not challenge any determination made by the company (or a Subsidiary PFIC) concerning its PFIC status or that the company (and each Subsidiary PFIC) was not, or will not be, a PFIC for any tax year. Each U.S. Holder should consult its own tax advisor regarding the PFIC status of the company and each Subsidiary PFIC.

If the company were a PFIC in any tax year and a U.S. Holder held common shares, such holder generally would be subject to special rules with respect to “excess distributions” made by the company on the common shares and with respect to gain from the disposition of common shares. An “excess distribution” generally is defined as the excess of distributions with respect to the common shares received by a U.S Holder in any tax year over 125% of the average annual distributions such U.S. Holder has received from the company during the shorter of the three preceding tax years, or such U.S. Holder’s holding period for the common shares. Generally, a U.S. Holder would be required to allocate any excess distribution or gain from the disposition of the common shares ratably over its holding period for the common shares. Such amounts allocated to the year of the disposition or excess distribution would be taxed as ordinary income, and amounts allocated to prior tax years would be taxed as ordinary income at the highest tax rate in effect for each such year and an interest charge at a rate applicable to underpayments of tax would apply.

While there are U.S. federal income tax elections that sometimes can be made to mitigate these adverse tax consequences (including, without limitation, the “QEF Election” and the “Mark-to-Market Election”), such elections are available in limited circumstances and must be made in a timely manner. U.S. Holders should be aware that, for each tax year, if any, that the company is a PFIC, the company can provide no assurances that it will satisfy the record keeping requirements of a PFIC, or that it will make available to U.S. Holders the information such U.S. Holders require to make a QEF Election under Section 1295 of the Code with respect of the company or any Subsidiary PFIC. U.S. Holders are urged to consult their own tax advisers regarding the potential application of the PFIC rules to the ownership and disposition of common shares, and the availability of certain U.S. tax elections under the PFIC rules.

H. Documents on display

We will furnish our shareholders with annual reports, which will include a review of operations and annual audited consolidated financial statements prepared in conformity with U.S. GAAP. We intend, although we are not obligated to do so, to furnish when requested by our shareholders quarterly reports by mail with the assistance of a corporate services provider, which will include unaudited interim financial information prepared in conformity with U.S. GAAP for each of the three quarters of each fiscal year following the end of each such quarter. We may discontinue providing quarterly reports at any time without prior notice to our shareholders. For additional information on the company, please consult our web page www.nxtenergy.com, or the SEDAR webpage http://sedar.com.

Our reports and other information, including this annual report and the exhibits hereto, as filed with the SEC in accordance with the Exchange Act, may be inspected and copied at the public reference facilities maintained by the SEC at 100 F Street, Washington, D.C. 20549. In addition, copies of such reports and other information filed with the SEC can be obtained from www.sec.gov.

ITEM 11. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Currency Fluctuations

We currently hold our cash in both Canadian and U.S. currency, yet we may earn revenue in U.S. currency and hold certain monetary assets and liabilities in other foreign currencies. Any transaction in a currency other than the Canadian dollar exposes us to the impact of exchange rate fluctuations between the Canadian and the foreign currencies. We do not currently engage in hedging activities to mitigate the effects of foreign currency fluctuation.

At December 31, 2012 we held U.S dollar cash, short term investments and restricted cash balances totaling US $5,276,619. Accordingly, a hypothetical 10% change in the value of one U.S. dollar expressed in Canadian dollars during the year ended December 31, 2012 would have had a $527,662 effect on the unrealized foreign exchange gain or loss.

Interest Fluctuations

At December 31, 2012 we held $5,540,963 in cash, cash equivalents, short term investments and restricted cash. If all this cash was held in an interest bearing account for a full year, an actual 1% change in interest rates during the year ended December 31, 2012 would have resulted in approximately a $55,410 change in interest income for the year.

ITEM 13. DEFAULTS, DIVIDEND ARREARAGES AND DELINQUENCIES

There have not been any defaults, dividend arrears or delinquencies.

ITEM 14. MATERIAL MODIFICATIONS TO THE RIGHTS OF SECURITY HOLDERS AND USE OF PROCEEDS

There have been no material modifications to the rights of security holders except as outlined in Item 4.B “Summary information on dependence on patents, licenses and contracts” within this Form 20-F.

ITEM 15. CONTROLS AND PROCEDURES

We maintain a set of disclosure controls and procedures designed to ensure that information required to be disclosed by the company in reports that it files or submits under the Exchange Act, is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms. Disclosure controls and procedures include controls and procedures designed to ensure that information required to be disclosed in our reports is accumulated and communicated to management, to allow timely decisions regarding required disclosure.

The company's Chief Executive Officer and Chief Financial Officer (the "Responsible Officers") are responsible for establishing and maintaining disclosure controls and procedures, or causing them to be designed under their supervision, for the company to provide reasonable assurance that material information relating to the company is made known to the Responsible Officers by others within the organization, particularly during the period in which the company's quarterly and year-end financial statements, Form 20-F and Canadian MD&A are being prepared.

As of December 31, 2012 we carried out an evaluation, under the supervision and with the participation of our management, including our Responsible Officers, of the effectiveness of the design and operation of our disclosure controls and procedures as defined in the Exchange Act Rule 13a-15(e).

Our management, under the supervision of the Responsible Officers, is also responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a-15(f) of the Exchange Act. Our internal control system was designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation and fair presentation of our consolidated financial statements for external purposes in accordance with generally accepted accounting principles. Our Responsible Officers assessed the effectiveness of our internal control over financial reporting as of December 31, 2012. In making this assessment, they used the criteria established in Internal Control–Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”).

Our internal controls over financial reporting were not required to be independently audited. Accordingly, no independent audit was performed over the effectiveness of internal controls as at December 31, 2012 and this annual report does not include an attestation report of the company’s registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to attestation by the company’s registered public accounting firm pursuant to rules of the SEC that permit the company to provide only management’s report in this annual report.

During this process, we identified the following material weaknesses in the company’s internal controls:

• Due to NXT’s limited number of staff, it is currently not feasible to achieve adequate segregation of incompatible duties. The company mitigates this deficiency by adding management and Audit Committee review procedures over the areas where inadequate segregation of duties are of the greatest concern; and

60 20-F for the year ended December 31, 2012

· The company does not retain staff with the specialized expertise required to prepare, nor does the company employ sufficient staff, to adequately review some complex or highly judgmental accounting issues. These complex areas include accounting for income taxes, stock based compensation expense, and other complex matters. The company mitigates this deficiency by preparing financial statements with their best judgments and estimates of the complex accounting matters and relies on reviews by management, external consultants and the Audit Committee for quality assurance.

Based upon this review the Chief Executive Officer and the Chief Financial Officer have concluded that due to the foregoing material weakness, the company’s internal control over financial reporting are not effective as at December 31, 2012 and as a result its disclosure controls and procedures are not effective as at December 31, 2012. The company reached this conclusion based upon their assessment that there is more than a remote likelihood that its internal control over financial reporting will not prevent or detect material misstatements if they should exist in our financial statements.

Changes in Internal Controls

During the period ended December 31, 2012, there were no changes in our internal control over financial reporting that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

ITEM 16A. AUDIT COMMITTEE FINANCIAL EXPERT

Our board of directors has determined that we have at least one audit committee financial expert (as defined under Item 16.A of Form 20-F) serving on our Audit Committee. Our Audit Committee financial expert is John Agee, a retired Certified Public Accountant (“CPA”). Mr. Agee is an “independent” director, as that term is defined under the listing standards of NASDAQ.

ITEM 16B. CODE OF ETHICS

We have adopted a Code of Ethics that applies to all of our directors, officers and employees. This Code of Ethics is incorporated in our Employee Handbook which forms an integral part of the employee contract. The Handbook contains sections on Business Ethics, Employee Practices and Conflicts of Interest.

During 2012 the company did not amend its Code of Ethics or grant any waiver, including any implicit waiver, from any provision of the Code of Ethics to any of its directors, officers or employees. Copies of NXT’s Code of Ethics are available without charge to any person upon request from NXT’s Chief Financial Officer at nxt_info@nxtenergy.com or at NXT’s headquarters at Suite 1400, 505 – 3^rd Street SW, Calgary Alberta, Canada, T2P 3E6.

The Board of Directors

NXT Energy Solutions Inc.

We consent to the incorporation by reference in the registration statements (No. 333-89251, 333-108465, 333-129803 and 333-146890) on Form S-8 of NXT Energy Solutions Inc. of our report dated April 16, 2013, with respect to the consolidated balance sheets of NXT Energy Solutions Inc. as of December 31, 2012 and 2011  and the related consolidated statements of income (loss) and comprehensive income (loss), shareholders’ equity and cash flows  for each of the years in the three-year period ended December 31, 2012, which report is incorporated by reference in the December 31, 2012 annual report on Form 20-F of NXT Energy Solutions Inc.

Our report dated April 16, 2013, contains an explanatory paragraph that states that NXT Energy Solutions Inc. has uncertainty about the timing and magnitude of future revenues, which raises substantial doubt about its ability to continue as a going concern. The consolidated financial statements do not include any adjustments that might result from the outcome of that uncertainty.

Consolidated Financial Statements

As at and for the year ended December 31, 2012

INDEPENDENT AUDITOR’S REPORT OF REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders of NXT Energy Solutions Inc.

We have audited the accompanying consolidated financial statements of NXT Energy Solutions Inc. (“the Company”), which comprise the consolidated balance sheets as at December 31, 2012 and 2011 and the consolidated statements of income (loss) and comprehensive income (loss), shareholders’ equity and cash flows for each of the years in the three-year period ended December 31, 2012, and notes, comprising a summary of significant accounting policies and other explanatory information.

Management's Responsibility for the Consolidated Financial Statements

Management is responsible for the preparation and fair presentation of these consolidated financial statements in accordance with US generally accepted accounting principles, and for such internal control as management determines is necessary to enable the preparation of consolidated financial statements that are free from material misstatement, whether due to fraud or error.

Auditors’ Responsibility

Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We conducted our audits in accordance with Canadian generally accepted auditing standards and the standards of the Public Accounting Oversight Board (United States). Those standards require that we comply with ethical requirements and plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the consolidated financial statements. The procedures selected depend on our judgment, including the assessment of the risks of material misstatement of the consolidated financial statements, whether due to fraud or error. In making those risk assessments, we consider internal control relevant to the entity's preparation and fair presentation of the consolidated financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entity's internal control. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of accounting estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements.

We believe that the audit evidence we have obtained in our audits is sufficient and appropriate to provide a basis for our audit opinion.

Opinion

In our opinion, the consolidated financial statements present fairly, in all material respects, the consolidated financial position of NXT Energy Solutions Inc. as at December 31, 2012 and 2011, and its consolidated results of operations and its consolidated cash flows for each of the years in the three-year period ended December 31, 2012 in accordance with US generally accepted accounting principles.

Emphasis of Matter

Without qualifying our opinion, we draw attention to Note 1 in the consolidated financial statements, which indicates that NXT Energy Solutions Inc. has uncertainty about the timing and magnitude of future revenues. These conditions, along with other matters as set forth in Note 1, indicate the existence of a material uncertainty that casts substantial doubt about the Company’s ability to continue as a going concern.

NXT ENERGY SOLUTIONS INC.

Notes to the Consolidated Financial Statements

As at and for the year ended December 31, 2012

(Expressed in Canadian dollars unless otherwise stated)

1. History and Future Operations

NXT Energy Solutions Inc. (the "Company" or "NXT") is a publicly traded company based in Calgary, Canada.

NXT owns a proprietary technology called Stress Field Detection ("SFD®"), an airborne survey system that is used in the oil and natural gas industry to help aid in identifying areas with hydrocarbon reservoir potential.  This technology was acquired from NXT's current Chief Executive Officer and President (the "CEO") under a technology transfer agreement (the "TTA") which has a term to December 31, 2015.  The TTA also involved the issuance by NXT of convertible Preferred Shares (see note 8).

Prior to 2006 the Company had engaged in extensive activities to develop, validate and obtain industry acceptance of SFD®, including conducting SFD® surveys for oil and gas industry partners on a cost recovery basis and participating as a joint venture partner in SFD® identified exploration wells.  By December 31, 2005 the Company had accumulated a deficit of approximately $47.6 million in conducting these activities.

This early period was effective in developing the SFD® technology to the point that the Company could commence the "commercialization" phase in 2006.  SFD® survey services began to be offered to potential clients engaged in oil and gas exploration activities with an initial focus on companies operating in the western Canadian sedimentary basin.  Subsequently, in 2008, NXT commenced to focus its sales activities towards international and frontier exploration markets.

NXT is still in the early stages of commercializing its SFD® technology, and the continued generation of positive cash flow from operations will depend largely on its ability to demonstrate the value of the SFD® survey system to a much wider client base.  NXT recognizes that this early commercialization phase can last for several years and that its' financial position is currently dependent upon a limited number of client projects, on obtaining additional financing when needed, and attracting future clients.

These consolidated financial statements have been prepared on a "going concern" basis in accordance with generally accepted accounting principles of the United States of America ("US GAAP").  The going concern basis of presentation assumes that NXT will continue in operation for the foreseeable future and will be able to realize its assets and discharge its liabilities and commitments in the normal course of business.  There is substantial doubt about the appropriateness of the use of the going concern assumption, primarily due to current uncertainty about the timing and magnitude of future SFD® survey revenues.  NXT recognizes that it has limited ability to support operations significantly beyond 2013 without generating sufficient new revenue sources or securing additional financing if required.

NXT realized significant growth and improvement in its financial position in 2012, and is working to expand operations in order to generate ongoing positive net income and cash flow from operations in future years with its existing business model.  However, the occurrence and timing of this outcome cannot be predicted with certainty.  NXT's ability to continue as a going concern will also depend on its ability to further develop, and ultimately retain the SFD® technology that was acquired under the TTA.

These consolidated financial statements do not include any adjustments to amounts and classifications of assets and liabilities or reported expenses that would be necessary should NXT be unable to raise additional capital or generate sufficient net income and cash flow from operations as required in future years in order to continue as a going concern.

2. Significant Accounting Policies

Basis of presentation

These consolidated financial statements as at and for the year ended December 31, 2012 have been prepared by management in accordance with US GAAP and by applying the same accounting policies and methods as used in preparing the consolidated financial statements for the years ended December 31, 2011 and 2010.

Consolidation

These consolidated financial statements reflect the accounts of the Company and its wholly owned subsidiaries.  All significant inter-company balances and transactions among NXT and its subsidiaries have been eliminated and are therefore not reflected in these consolidated financial statements.

Estimates and Assumptions

The preparation of these consolidated financial statements requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities, including the disclosure of contingent assets and liabilities, at the date of these consolidated financial statements as well as revenues and expenses recorded during the reporting periods.

Estimates made relate to allowances for doubtful accounts, estimated useful lives of assets, provisions for contingent liabilities, measurement of stock-based compensation expense, valuation of deferred tax assets, estimates for asset retirement obligations, the valuation of derivative and equity instruments and the preferred shares (which may include estimates of the likelihood that the conversion feature of the preferred shares will be achieved in future). The estimates and assumptions used are based upon management's best estimate. Estimates and assumptions are reviewed periodically and the effects of revisions are reflected in the period when determined. Actual results may differ from those estimates.

Cash and Cash Equivalents

Cash and cash equivalents consist of cash on hand and short term securities with an original maturity less than 90 days from the date of acquisition.

F-6

Short Term Investments

Short term investments are recorded at fair value, and include short term securities, held by a major Canadian chartered bank, with original maturity dates greater than 90 days but less than one year.

Revenue Recognition

Revenue from SFD®survey contracts (net of any related foreign sales tax) is recognized on a completed contract basis.  Amounts received or invoiced in advance of completion of the contract is reflected as deferred revenue and classified as a current liability.  All related survey expenditures and obligations related to uncompleted contracts are  reflected as work-in-progress and classified as current assets.  Upon completion of the related contract, unearned revenue and the related work-in-progress are reflected in the statement of income (loss) as either revenue or survey cost.  Sales commissions incurred on the contracts are included in survey costs.  Survey cost does not include any amortization or depreciation of property and equipment.

Derivative Instruments

Derivative instruments are recognized on the balance sheet at fair value with realized and unrealized gains (losses) recognized in the Consolidated Statement of income (loss).  Any outstanding derivatives are required to be included into one of three categories based on a fair value hierarchy (which in 2012 was Level III  - based on valuation techniques that refer to both observable and unobservable market data).  NXT does not apply hedge accounting to any of its derivatives.

Property and Equipment

Property and equipment is recorded at cost, less accumulated depreciation and amortization, which is recorded over the estimated service lives of the assets using the following annual rates and methods:

Computer hardware	30% declining balance
Computer software	100% declining balance
Furniture and other equipment	20% declining balance
Leasehold improvements	over the remaining term of the lease

Management periodically reviews the carrying values of  property and equipment to ensure that any impairment in value is recognized and reflected in results of operations.

Research and Development Expenditures

Research and development ("R&D") expenditures incurred to develop, improve and test the SFD® survey system and related components are expensed as incurred.  Any intellectual property that is acquired for the purpose of enhancing research and development projects, if there is no alternative use for the intellectual property, is expensed in the period acquired.  No significant R&D was incurred in the years ended 2010, 2011 and 2012.

Foreign Currency Translation

The Company's functional currency is the Canadian dollar. Revenues and expenses denominated in foreign currencies are translated into Canadian dollars at the average exchange rate for the applicable period. Shareholders' equity accounts are translated into Canadian dollars using the exchange rates in effect at the time of the transaction. Monetary assets and liabilities are translated into Canadian dollars at the exchange rate in affect at the end of the applicable period. Non monetary assets and liabilities (including work-in-progress and deferred revenue balances) are recorded at the relevant exchange rates for the period in which the balances arose. Any related foreign exchange gains and losses resulting from these translations are included in the determination of net income (loss) for the year.

Prior to 2010, NXT had active subsidiaries which had the US dollar as their functional currency.  Foreign currency translation adjustments related to the consolidation of these subsidiaries is the only component of accumulated other comprehensive income, which is included in shareholders' equity.

Income Taxes

NXT follows the asset and liability method of accounting for income taxes. This method recognizes deferred income tax assets and liabilities based on temporary differences in reported amounts for financial statement and income tax purposes, at the income tax rates expected to apply in the future periods when the temporary differences are expected to be reversed or realized.  The effect of a change in income tax rates on deferred income tax assets and deferred income tax liabilities is recognized in income in the period when the tax rate change is enacted.  Valuation allowances are provided when necessary to reduce deferred tax assets to the amount that is more likely than not to be realized.

Stock based compensation expense

NXT follows the fair value method of accounting for stock options that are granted to acquire common shares under NXT's stock option plan.  Under this method, an estimate of the fair value of the cost of stock options that are granted to employees, directors and consultants is calculated using the Black-Scholes option pricing model and charged to income over the future vesting period of the options, with a corresponding increase recorded in contributed capital.  Upon exercise of the stock options, the consideration received by NXT, and the related amount which was previously recorded in contributed capital, is recognized as an increase in the recorded value of common shares of the Company.

Stock-based compensation related to options granted to non-employees is periodically re-measured until the earlier of the completion of their service period or when the vesting period is completed.  Changes to the re-measured compensation are recognized in the period of change and amortized over the remaining life of the vesting period in the same manner as the original option.

Income (loss) per share

Basic income (loss) per share amounts are calculated by dividing net income (loss) by the weighted average number of common shares that are outstanding for the fiscal period.  Shares issued during the period are weighted for the portion of the period that the shares were outstanding.  Diluted income (loss) per share is computed using the treasury stock method, whereby the weighted average number of shares outstanding is increased to include any additional shares that would be issued from the assumed exercise of stock options and common share purchase warrants.  The incremental number of shares added under the treasury stock method assumes that outstanding stock options and warrants that are exercisable at exercise prices below the Company's average market price (or “in-the-money”) for the applicable fiscal period are exercised and then that number of incremental shares is reduced by the number of shares that could have been repurchased by the Company from the issuance proceeds, using the average market price of the Company’s shares for the applicable fiscal period.

No addition to the basic number of shares is made when calculating the diluted number of shares if the diluted per share amounts become anti-dilutive (such as occurs in the case of a net loss for the period).

F-7

3. Restricted cash

Restricted cash consists of US dollar money market securities (plus accrued interest) which have been deposited by NXT with financial institutions as security in order for these institutions to issue bank letters of credit for the benefit of third party clients.   These letters of credit include contractual performance bonds related to conducting certain SFD® surveys.

6. Asset retirement obligation

Asset retirement obligations ("ARO") relate to oil and natural gas wells in which NXT has outstanding abandonment and reclamation obligations in accordance with government regulations. The Company's obligation relates to its interests in 8 gross (1.1 net) wells that were drilled in the years 2000 through 2004. ARO have an estimated future liability of approximately $62,000 and is based on estimates of the future timing and costs to remediate, reclaim and abandon the wells within the next three years.  The net present value of the ARO is as noted below, and has been calculated using an inflation rate of 3.4% and discounted using a credit-adjusted risk-free interest rate of 10%.

(i) On February 16, 2011 NXT closed a non-brokered private placement (the "2011 Placement") for aggregate proceeds of $1,600,300 ($1,487,827 net of costs incurred of $112,473) including $40,000 subscribed for by two Officers of the Company.  NXT issued a total of 3,200,600 units at a price of $0.50 per unit, with each unit consisting of one NXT common share and one warrant, with each warrant entitling the holder to acquire an additional common share at a price of $0.60 per share on or before the expiry date of February 16, 2012 (see also note 11).  In connection with closing of the 2011 Placement, NXT paid finder's fees which included $72,600 cash and 145,320 warrants, which had the same terms as the other warrants that were issued.

The common shares were recorded at a value equal to the net proceeds received of $1,488,267 and reduced by $329,386 which was the estimated fair value attributed to the 3,345,920 warrants that were issued in the 2011 Placement.

(ii) In March and May 2012, NXT conducted private placement financings (the "2012 Financings") which consisted of units issued at a price of US $0.75 (the "Units"). Each Unit consisted of one NXT common share and one warrant (the "Warrants") to purchase an additional NXT common share at a price of US $1.20. The Warrants have a term of two years from the date of issue, and the expiry can be accelerated at the option of NXT in the event that it issues a press release advising that its common shares have traded on the US OTCBB Exchange at a price exceeding US $1.50 for 20 consecutive trading days. Any Warrants subject to acceleration shall expire 30 days after such notice.

In connection with the 2012 Financings, NXT paid finder's fees totalling US $183,612 and issued a total of 244,816 finder's warrants (which have the same terms as the Warrants noted above).  The 2012 Financings had three separate closings in March, 2012 and one on May 4, 2012, which are summarized as follows:

	March,		May 4,
	2012		2012		total
Proceeds (in US dollars)	$	2,216,005	$	977,500	$	3,193,505
Number of common shares issued		2,954,672		1,303,333		4,258,005
Number of Warrants issued		2,954,672		1,303,333		4,258,005
Number of finder's warrants issued		162,416		82,400		244,816
		3,117,088		1,385,733		4,502,821

Two Officers of the Company subscribed for a total of US $40,000 of the 2012 Financings.

The common shares that were issued under the 2012 Financings were recorded at a value equal to the proceeds received of $3,183,132 ($2,886,024, net of related issue costs totalling $297,108), and reduced by $409,143 which was the estimated fair value attributed to the 4,502,821 Warrants that were issued (see also note 11).

8. Preferred shares

The Company is authorized to issue an unlimited number of preferred shares, issuable in series.

In 2005, the Company issued 10,000,000 series 1 preferred shares (the "Preferred Shares") to its CEO pursuant to the execution of the Technical Transfer Agreement (see note 1) in exchange for the rights to utilize the SFD® technology for hydrocarbon exploration.

These Preferred Shares are non-voting, and are conditionally convertible into NXT common shares under the following terms:

● 2,000,000 of the Preferred Shares became convertible into common shares upon issue. In April 2013, the holder gave notice to NXT to formally convert (effective April 30, 2013) these 2,000,000 Preferred Shares into 2,000,000 common shares.

● The remaining 8,000,000 Preferred Shares are subject to conditions related to potential future conversion. They may become convertible into common shares in four separate increments of 2,000,000 Preferred Shares each, should NXT achieve specified cumulative revenue thresholds of US $50 million, US $100 million, US $250 million and US $500 million prior to December 31, 2015.

● An additional bonus of 1,000,000 Preferred Shares are issuable in the event that cumulative revenues exceed US $500 million.

● Cumulative revenue is defined as the sum of total revenue earned plus proceeds from the sale of assets accumulated since January 1, 2007, all denominated in United States dollars, and calculated in accordance with generally accepted accounting principles.

● In the event that the final cumulative revenue threshold of US $500 million is not achieved by December 31, 2015, NXT has the option to either redeem any remaining unconverted Preferred Shares for a price of $0.001 per share and forfeit its rights to the SFD® technology, or elect to retain the ownership of the SFD® technology by converting all of the remaining Preferred Shares into common shares.

The Preferred Shares do not participate in any dividends, and are not transferable except with the consent of the Board of Directors of NXT.

As at December 31, 2012, the Company had generated cumulative revenue of approximately US $23.1 million (December 31, 2011 - US $12.2 million) that is eligible to be applied to the above noted conversion thresholds.

The Preferred Shares were originally recorded at their estimated fair value as at December 31, 2005, with the total substantially assigned to the portion which was immediately convertible.  The remaining Preferred Shares were assigned a nominal value, reflecting the uncertainty that the required revenue objectives would be achieved to allow conversion into common shares, as follows:

	# of Preferred		recorded
	Shares		value
convertible upon issue effective December 31, 2005		2,000,000	$	3,256,400
conditionally convertible on or before December 31, 2015		8,000,000		232,600
		10,000,000		3,489,000

A total of 2,000,000 of the Preferred Shares (see note 8) are included in the above noted basic income (loss) per share calculations, as the criteria for them to convert to common shares have been met for each period.  The remaining 8,000,000 Preferred Shares are contingently issuable, and are included in the diluted number of shares outstanding .

In periods in which a loss results, all outstanding stock options, common share purchase warrants and certain of the Preferred Shares are excluded from the diluted loss per share calculations as they are anti-dilutive.

● A total of 300,000 stock options were granted in August, 2012, with an average exercise price of $1.20, expiring August 2017, and with 20% of the options vesting after each 3 month period.

● In July 2012 a total of 830,000 stock options with an exercise price of $0.86 were granted to Directors and Officers of NXT. In addition, two Directors of NXT surrendered for cancellation a total of 140,000 vested stock options, which had an exercise price of $0.63 per share, and an expiry date of December 12, 2012.

● A total of 400,000 stock options were granted in December, 2011, at an average exercise price of $2.50, expiring June 1, 2013, and with 25% of the options vesting after each 3 month period. In 2012, a total of 200,000 of these options were forfeited and the remaining 200,000 expired.

● A total of 214,800 of the 504,800 stock options which were granted in July, 2011 at an exercise price of $1.16 per share had immediate vesting.

● In January, 2011 an Officer of the Company was granted 150,000 options at an excise price of $0.53 per share, and with one third of the options vesting at the date of grant and one-third vesting at the end of each of the following two years.

As of December 31, 2012 there was $967,000 (December 31, 2011 - $338,000) of unamortized stock based compensation expense related to non-vested stock options.  This amount will be recognized in future expense over the remaining vesting periods of the underlying stock options.

11. Warrants to purchase common shares

The following is a summary of outstanding warrants to purchase common shares:

(i)  In February, 2011 NXT closed a private placement financing of Units (see note 7(i)) which included a total of 3,345,920 warrants which had an exercise price of $0.60 and an expiry date of February 16, 2012.  The estimated fair value attributed to the warrants that were issued in 2011 was $329,386 (see note 12(2)).

(ii) The estimated fair value attributed to the 4,502,821 total US$ Warrants that were issued in the 2012 Financing (see note 7(ii)) was $409,143, determined using the weighted average assumptions listed in note 12(2).

12.  Financial instruments

1) Non-derivative financial instruments

The Company's non-derivative financial instruments consist of cash and cash equivalents, short term investments, restricted cash, accounts receivable, and accounts payables and accrued liabilities. The carrying value of these financial instruments approximates their fair values due to their short terms to maturity. NXT is not exposed to significant interest or credit risks arising from these financial instruments. NXT is exposed to foreign exchange risk as a result of holding U.S. and Colombian denominated financial instruments.

2) Derivative financial instruments

As the exercise price of the Warrants issued in 2012 (see note 7) is in US dollars, which is a currency other than the functional currency of NXT, the fair value of this derivative financial instrument, is required to be reflected as a derivative on the balance sheet. The amount recorded for this instrument, which is included with current liabilities, will be adjusted to fair value at each period end over the life of the Warrants, with the changes in fair value reflected in earnings.

Under US GAAP fair value measurement standards, financial instruments that are recorded at fair value on a recurring basis are required to be classified into one of three categories based upon a fair value hierarchy. The Company's only financial instruments recorded at fair value on a recurring basis are the US dollar denominated warrants. NXT has classified these derivative financial instruments as level III where the fair value is determined by using valuation techniques that refer to both observable and unobservable market data. The valuation model was based on the Black-Scholes inputs noted below, as well as a discount to reflect the potential dilution impact upon exercise of the warrants and NXT's low stock market liquidity.

A continuity of the fair value of derivative instruments balance is as follows:

	2012			2011
Balance, start of the year	$	-		$	-
Value attributed to US$ common share purchase warrants issued
in 2012 Financings (see note 7(ii))		409,143			-

F-12

The value attributed to warrants that have been issued by NXT was calculated at issuance using the Black-Scholes valuation model utilizing the following weighted average assumptions:

	2012			2011
Expected dividends paid per common share	Nil			Nil
Expected life in years		1			0.8
Expected volatility in the price of common shares		66	%		94	%
Risk free interest rate		1.0	%		1.5	%
Weighted average fair market value per warrant issued	$	US 0.05		$	0.14

13. Income tax expense

NXT periodically earns revenues while operating outside of Canada as a non-resident within certain foreign jurisdictions.  Payments made to NXT for services rendered to clients in such countries may be subject to withholding taxes, which are only recoverable in certain circumstances.  During 2012, NXT incurred foreign withholding taxes on a portion of its revenues that were generated in Latin and South America.  Although such foreign taxes paid can potentially be utilized in Canada as a foreign tax credit against future taxable earnings from the foreign jurisdictions, a full valuation allowance has been provided against this benefit.

Income tax expense is different from the expected amount that would be computed by applying the statutory Canadian federal and provincial income tax rates to NXT's income (loss) before income taxes as follows:

	2012			2011			2010
Net income (loss) before income taxes	$	2,489,149		$	(3,584,601	)	$	(4,452,428	)

Income taxes paid in foreign jurisdictions		426,421			-			-
Current income tax expense	$	426,421		$	-		$	-

The Company has significant unrecorded deferred income tax assets for which a full valuation allowance has been provided due to uncertainty regarding their potential utilization, as follows:

	2012			2011			2010
Net operating losses carried forward:
USA (expiration dates 2020 to 2026)	$	1,908,285		$	2,014,577		$	1,970,205

Less valuation allowance		(7,310,372	)		(7,997,004	)		(7,431,457	)
		-			-			-

Certain income taxation years remain subject to review and assessment by the relevant tax authorities in Canada and the United States.  NXT has no unrecorded tax benefits and no amounts are included in these consolidated financial statements for amounts related to interest and penalties on income tax balances.

14. Changes in non-cash working capital

The change in non-cash working capital is comprised of:

	2012			2011			2010
Accounts receivable		(350,077	)		(119,160	)		1,139,309

15. Commitments and contingencies

NXT has an operating lease commitment on its Calgary office space for a term through April 30, 2015 at a minimum monthly lease payment of $26,138 (including estimated operating costs).  As at December 31, 2012, the estimated remaining minimum annual lease commitment is as follows:

for the	total minimum
year ending	lease
December 31	payments
2013	$	304,382
2014		304,382
2015		101,461
		710,225

Payments for this premises lease were $353,379 for the year ended December 31, 2012 (2011 - $347,130, 2010 - $358,642).

NXT currently does not own any of the aircraft which are used in its' survey operations, but has an annual agreement (which expires in January, 2014) to utilize a minimum annual volume of aircraft charter hours.  The contract has a minimum commitment of $317,000 for 2013.

In 2003 NXT was named as one of several defendants in a statement of claim related to an aircraft crash.  The plaintiffs alleged that all defendants were in breach of an aircraft ferry flight contract and were seeking damages of $450,000, but did not pursue their claim against NXT for over six years.  NXT was not a party to the contract and its position was that the claim was without merit.  The claim against NXT was discontinued in October 2012.

Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2012

Significant Accounting Policies Policies

Basis of presentation

These consolidated financial statements as at and for the year ended December 31, 2012 have been prepared by management in accordance with US GAAP and by applying the same accounting policies and methods as used in preparing the consolidated financial statements for the years ended December 31, 2011 and 2010.

Consolidation

These consolidated financial statements reflect the accounts of the Company and its wholly owned subsidiaries.  All significant inter-company balances and transactions among NXT and its subsidiaries have been eliminated and are therefore not reflected in these consolidated financial statements.

Estimates and Assumptions

The preparation of these consolidated financial statements requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities, including the disclosure of contingent assets and liabilities, at the date of these consolidated financial statements as well as revenues and expenses recorded during the reporting periods.

Estimates made relate to allowances for doubtful accounts, estimated useful lives of assets, provisions for contingent liabilities, measurement of stock-based compensation expense, valuation of deferred tax assets, estimates for asset retirement obligations, the valuation of derivative and equity instruments and the preferred shares (which may include estimates of the likelihood that the conversion feature of the preferred shares will be achieved in future). The estimates and assumptions used are based upon management's best estimate. Estimates and assumptions are reviewed periodically and the effects of revisions are reflected in the period when determined. Actual results may differ from those estimates.

Cash and Cash Equivalents

Cash and cash equivalents consist of cash on hand and short term securities with an original maturity less than 90 days from the date of acquisition.

Short Term Investments

Short term investments are recorded at fair value, and include short term securities, held by a major Canadian chartered bank, with original maturity dates greater than 90 days but less than one year.

Revenue Recognition

Revenue from SFD®survey contracts (net of any related foreign sales tax) is recognized on a completed contract basis.  Amounts received or invoiced in advance of completion of the contract is reflected as deferred revenue and classified as a current liability.  All related survey expenditures and obligations related to uncompleted contracts are  reflected as work-in-progress and classified as current assets.  Upon completion of the related contract, unearned revenue and the related work-in-progress are reflected in the statement of income (loss) as either revenue or survey cost.  Sales commissions incurred on the contracts are included in survey costs.  Survey cost does not include any amortization or depreciation of property and equipment.

Derivative Instruments

Derivative instruments are recognized on the balance sheet at fair value with realized and unrealized gains (losses) recognized in the Consolidated Statement of income (loss).  Any outstanding derivatives are required to be included into one of three categories based on a fair value hierarchy (which in 2012 was Level III  - based on valuation techniques that refer to both observable and unobservable market data).  NXT does not apply hedge accounting to any of its derivatives.

Property and Equipment

Property and equipment is recorded at cost, less accumulated depreciation and amortization, which is recorded over the estimated service lives of the assets using the following annual rates and methods:

Computer hardware	30% declining balance
Computer software	100% declining balance
Furniture and other equipment	20% declining balance
Leasehold improvements	over the remaining term of the lease

Management periodically reviews the carrying values of  property and equipment to ensure that any impairment in value is recognized and reflected in results of operations.

Research and Development Expenditures

Research and development ("R&D") expenditures incurred to develop, improve and test the SFD® survey system and related components are expensed as incurred.  Any intellectual property that is acquired for the purpose of enhancing research and development projects, if there is no alternative use for the intellectual property, is expensed in the period acquired.  No significant R&D was incurred in the years ended 2010, 2011 and 2012.

Foreign Currency Translation

The Company's functional currency is the Canadian dollar. Revenues and expenses denominated in foreign currencies are translated into Canadian dollars at the average exchange rate for the applicable period. Shareholders' equity accounts are translated into Canadian dollars using the exchange rates in effect at the time of the transaction. Monetary assets and liabilities are translated into Canadian dollars at the exchange rate in affect at the end of the applicable period. Non monetary assets and liabilities (including work-in-progress and deferred revenue balances) are recorded at the relevant exchange rates for the period in which the balances arose. Any related foreign exchange gains and losses resulting from these translations are included in the determination of net income (loss) for the year.

Prior to 2010, NXT had active subsidiaries which had the US dollar as their functional currency.  Foreign currency translation adjustments related to the consolidation of these subsidiaries is the only component of accumulated other comprehensive income, which is included in shareholders' equity.

Income Taxes

NXT follows the asset and liability method of accounting for income taxes. This method recognizes deferred income tax assets and liabilities based on temporary differences in reported amounts for financial statement and income tax purposes, at the income tax rates expected to apply in the future periods when the temporary differences are expected to be reversed or realized.  The effect of a change in income tax rates on deferred income tax assets and deferred income tax liabilities is recognized in income in the period when the tax rate change is enacted.  Valuation allowances are provided when necessary to reduce deferred tax assets to the amount that is more likely than not to be realized.

Stock based compensation expense

NXT follows the fair value method of accounting for stock options that are granted to acquire common shares under NXT's stock option plan.  Under this method, an estimate of the fair value of the cost of stock options that are granted to employees, directors and consultants is calculated using the Black-Scholes option pricing model and charged to income over the future vesting period of the options, with a corresponding increase recorded in contributed capital.  Upon exercise of the stock options, the consideration received by NXT, and the related amount which was previously recorded in contributed capital, is recognized as an increase in the recorded value of common shares of the Company.

Stock-based compensation related to options granted to non-employees is periodically re-measured until the earlier of the completion of their service period or when the vesting period is completed.  Changes to the re-measured compensation are recognized in the period of change and amortized over the remaining life of the vesting period in the same manner as the original option.

Income (loss) per share

Basic income (loss) per share amounts are calculated by dividing net income (loss) by the weighted average number of common shares that are outstanding for the fiscal period.  Shares issued during the period are weighted for the portion of the period that the shares were outstanding.  Diluted income (loss) per share is computed using the treasury stock method, whereby the weighted average number of shares outstanding is increased to include any additional shares that would be issued from the assumed exercise of stock options and common share purchase warrants.  The incremental number of shares added under the treasury stock method assumes that outstanding stock options and warrants that are exercisable at exercise prices below the Company's average market price (or “in-the-money”) for the applicable fiscal period are exercised and then that number of incremental shares is reduced by the number of shares that could have been repurchased by the Company from the issuance proceeds, using the average market price of the Company’s shares for the applicable fiscal period.

No addition to the basic number of shares is made when calculating the diluted number of shares if the diluted per share amounts become anti-dilutive (such as occurs in the case of a net loss for the period).

Significant Accounting Policies

Significant Accounting Policies

Basis of presentation

These consolidated financial statements as at and for the year ended December 31, 2012 have been prepared by management in accordance with US GAAP and by applying the same accounting policies and methods as used in preparing the consolidated financial statements for the years ended December 31, 2011 and 2010.

Consolidation

These consolidated financial statements reflect the accounts of the Company and its wholly owned subsidiaries.  All significant inter-company balances and transactions among NXT and its subsidiaries have been eliminated and are therefore not reflected in these consolidated financial statements.

Estimates and Assumptions

The preparation of these consolidated financial statements requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities, including the disclosure of contingent assets and liabilities, at the date of these consolidated financial statements as well as revenues and expenses recorded during the reporting periods.

Estimates made relate to allowances for doubtful accounts, estimated useful lives of assets, provisions for contingent liabilities, measurement of stock-based compensation expense, valuation of deferred tax assets, estimates for asset retirement obligations, the valuation of derivative and equity instruments and the preferred shares (which may include estimates of the likelihood that the conversion feature of the preferred shares will be achieved in future). The estimates and assumptions used are based upon management's best estimate. Estimates and assumptions are reviewed periodically and the effects of revisions are reflected in the period when determined. Actual results may differ from those estimates.

Cash and Cash Equivalents

Cash and cash equivalents consist of cash on hand and short term securities with an original maturity less than 90 days from the date of acquisition.

Short Term Investments

Short term investments are recorded at fair value, and include short term securities, held by a major Canadian chartered bank, with original maturity dates greater than 90 days but less than one year.

Revenue Recognition

Revenue from SFD®survey contracts (net of any related foreign sales tax) is recognized on a completed contract basis.  Amounts received or invoiced in advance of completion of the contract is reflected as deferred revenue and classified as a current liability.  All related survey expenditures and obligations related to uncompleted contracts are  reflected as work-in-progress and classified as current assets.  Upon completion of the related contract, unearned revenue and the related work-in-progress are reflected in the statement of income (loss) as either revenue or survey cost.  Sales commissions incurred on the contracts are included in survey costs.  Survey cost does not include any amortization or depreciation of property and equipment.

Derivative Instruments

Derivative instruments are recognized on the balance sheet at fair value with realized and unrealized gains (losses) recognized in the Consolidated Statement of income (loss).  Any outstanding derivatives are required to be included into one of three categories based on a fair value hierarchy (which in 2012 was Level III  - based on valuation techniques that refer to both observable and unobservable market data).  NXT does not apply hedge accounting to any of its derivatives.

Property and Equipment

Property and equipment is recorded at cost, less accumulated depreciation and amortization, which is recorded over the estimated service lives of the assets using the following annual rates and methods:

Computer hardware	30% declining balance
Computer software	100% declining balance
Furniture and other equipment	20% declining balance
Leasehold improvements	over the remaining term of the lease

Management periodically reviews the carrying values of  property and equipment to ensure that any impairment in value is recognized and reflected in results of operations.

Research and Development Expenditures

Research and development ("R&D") expenditures incurred to develop, improve and test the SFD® survey system and related components are expensed as incurred.  Any intellectual property that is acquired for the purpose of enhancing research and development projects, if there is no alternative use for the intellectual property, is expensed in the period acquired.  No significant R&D was incurred in the years ended 2010, 2011 and 2012.

Foreign Currency Translation

The Company's functional currency is the Canadian dollar. Revenues and expenses denominated in foreign currencies are translated into Canadian dollars at the average exchange rate for the applicable period. Shareholders' equity accounts are translated into Canadian dollars using the exchange rates in effect at the time of the transaction. Monetary assets and liabilities are translated into Canadian dollars at the exchange rate in affect at the end of the applicable period. Non monetary assets and liabilities (including work-in-progress and deferred revenue balances) are recorded at the relevant exchange rates for the period in which the balances arose. Any related foreign exchange gains and losses resulting from these translations are included in the determination of net income (loss) for the year.

Prior to 2010, NXT had active subsidiaries which had the US dollar as their functional currency.  Foreign currency translation adjustments related to the consolidation of these subsidiaries is the only component of accumulated other comprehensive income, which is included in shareholders' equity.

Income Taxes

NXT follows the asset and liability method of accounting for income taxes. This method recognizes deferred income tax assets and liabilities based on temporary differences in reported amounts for financial statement and income tax purposes, at the income tax rates expected to apply in the future periods when the temporary differences are expected to be reversed or realized.  The effect of a change in income tax rates on deferred income tax assets and deferred income tax liabilities is recognized in income in the period when the tax rate change is enacted.  Valuation allowances are provided when necessary to reduce deferred tax assets to the amount that is more likely than not to be realized.

Stock based compensation expense

NXT follows the fair value method of accounting for stock options that are granted to acquire common shares under NXT's stock option plan.  Under this method, an estimate of the fair value of the cost of stock options that are granted to employees, directors and consultants is calculated using the Black-Scholes option pricing model and charged to income over the future vesting period of the options, with a corresponding increase recorded in contributed capital.  Upon exercise of the stock options, the consideration received by NXT, and the related amount which was previously recorded in contributed capital, is recognized as an increase in the recorded value of common shares of the Company.

Stock-based compensation related to options granted to non-employees is periodically re-measured until the earlier of the completion of their service period or when the vesting period is completed.  Changes to the re-measured compensation are recognized in the period of change and amortized over the remaining life of the vesting period in the same manner as the original option.

Income (loss) per share

Basic income (loss) per share amounts are calculated by dividing net income (loss) by the weighted average number of common shares that are outstanding for the fiscal period.  Shares issued during the period are weighted for the portion of the period that the shares were outstanding.  Diluted income (loss) per share is computed using the treasury stock method, whereby the weighted average number of shares outstanding is increased to include any additional shares that would be issued from the assumed exercise of stock options and common share purchase warrants.  The incremental number of shares added under the treasury stock method assumes that outstanding stock options and warrants that are exercisable at exercise prices below the Company's average market price (or “in-the-money”) for the applicable fiscal period are exercised and then that number of incremental shares is reduced by the number of shares that could have been repurchased by the Company from the issuance proceeds, using the average market price of the Company’s shares for the applicable fiscal period.

No addition to the basic number of shares is made when calculating the diluted number of shares if the diluted per share amounts become anti-dilutive (such as occurs in the case of a net loss for the period).

History And Future Operations

History and Future Operations

NXT Energy Solutions Inc. (the "Company" or "NXT") is a publicly traded company based in Calgary, Canada.

NXT owns a proprietary technology called Stress Field Detection ("SFD®"), an airborne survey system that is used in the oil and natural gas industry to help aid in identifying areas with hydrocarbon reservoir potential.  This technology was acquired from NXT's current Chief Executive Officer and President (the "CEO") under a technology transfer agreement (the "TTA") which has a term to December 31, 2015.  The TTA also involved the issuance by NXT of convertible Preferred Shares (see note 8).

Prior to 2006 the Company had engaged in extensive activities to develop, validate and obtain industry acceptance of SFD®, including conducting SFD® surveys for oil and gas industry partners on a cost recovery basis and participating as a joint venture partner in SFD® identified exploration wells.  By December 31, 2005 the Company had accumulated a deficit of approximately $47.6 million in conducting these activities.

This early period was effective in developing the SFD® technology to the point that the Company could commence the "commercialization" phase in 2006.  SFD® survey services began to be offered to potential clients engaged in oil and gas exploration activities with an initial focus on companies operating in the western Canadian sedimentary basin.  Subsequently, in 2008, NXT commenced to focus its sales activities towards international and frontier exploration markets.

NXT is still in the early stages of commercializing its SFD® technology, and the continued generation of positive cash flow from operations will depend largely on its ability to demonstrate the value of the SFD® survey system to a much wider client base.  NXT recognizes that this early commercialization phase can last for several years and that its' financial position is currently dependent upon a limited number of client projects, on obtaining additional financing when needed, and attracting future clients.

These consolidated financial statements have been prepared on a "going concern" basis in accordance with generally accepted accounting principles of the United States of America ("US GAAP").  The going concern basis of presentation assumes that NXT will continue in operation for the foreseeable future and will be able to realize its assets and discharge its liabilities and commitments in the normal course of business.  There is substantial doubt about the appropriateness of the use of the going concern assumption, primarily due to current uncertainty about the timing and magnitude of future SFD® survey revenues.  NXT recognizes that it has limited ability to support operations significantly beyond 2013 without generating sufficient new revenue sources or securing additional financing if required.

NXT realized significant growth and improvement in its financial position in 2012, and is working to expand operations in order to generate ongoing positive net income and cash flow from operations in future years with its existing business model.  However, the occurrence and timing of this outcome cannot be predicted with certainty.  NXT's ability to continue as a going concern will also depend on its ability to further develop, and ultimately retain the SFD® technology that was acquired under the TTA.

These consolidated financial statements do not include any adjustments to amounts and classifications of assets and liabilities or reported expenses that would be necessary should NXT be unable to raise additional capital or generate sufficient net income and cash flow from operations as required in future years in order to continue as a going concern.

Financial Instruments

Financial instruments

1) Non-derivative financial instruments

The Company's non-derivative financial instruments consist of cash and cash equivalents, short term investments, restricted cash, accounts receivable, and accounts payables and accrued liabilities. The carrying value of these financial instruments approximates their fair values due to their short terms to maturity. NXT is not exposed to significant interest or credit risks arising from these financial instruments. NXT is exposed to foreign exchange risk as a result of holding U.S. and Colombian denominated financial instruments.

2) Derivative financial instruments

As the exercise price of the Warrants issued in 2012 (see note 7) is in US dollars, which is a currency other than the functional currency of NXT, the fair value of this derivative financial instrument, is required to be reflected as a derivative on the balance sheet. The amount recorded for this instrument, which is included with current liabilities, will be adjusted to fair value at each period end over the life of the Warrants, with the changes in fair value reflected in earnings.

Under US GAAP fair value measurement standards, financial instruments that are recorded at fair value on a recurring basis are required to be classified into one of three categories based upon a fair value hierarchy. The Company's only financial instruments recorded at fair value on a recurring basis are the US dollar denominated warrants. NXT has classified these derivative financial instruments as level III where the fair value is determined by using valuation techniques that refer to both observable and unobservable market data. The valuation model was based on the Black-Scholes inputs noted below, as well as a discount to reflect the potential dilution impact upon exercise of the warrants and NXT's low stock market liquidity.

A continuity of the fair value of derivative instruments balance is as follows:

	2012			2011
Balance, start of the year	$	-		$	-
Value attributed to US$ common share purchase warrants issued
in 2012 Financings (see note 7(ii))		409,143			-
Change in fair value during the year		(168,143	)		-
	$	241,000		$	-

The value attributed to warrants that have been issued by NXT was calculated at issuance using the Black-Scholes valuation model utilizing the following weighted average assumptions:

	2012			2011
Expected dividends paid per common share	Nil			Nil
Expected life in years		1			0.8
Expected volatility in the price of common shares		66	%		94	%

Asset Retirement Obligation

Asset retirement obligation

Asset retirement obligations ("ARO") relate to oil and natural gas wells in which NXT has outstanding abandonment and reclamation obligations in accordance with government regulations. The Company's obligation relates to its interests in 8 gross (1.1 net) wells that were drilled in the years 2000 through 2004. ARO have an estimated future liability of approximately $62,000 and is based on estimates of the future timing and costs to remediate, reclaim and abandon the wells within the next three years.  The net present value of the ARO is as noted below, and has been calculated using an inflation rate of 3.4% and discounted using a credit-adjusted risk-free interest rate of 10%.

Income Tax Expense

Income tax expense

NXT periodically earns revenues while operating outside of Canada as a non-resident within certain foreign jurisdictions.  Payments made to NXT for services rendered to clients in such countries may be subject to withholding taxes, which are only recoverable in certain circumstances.  During 2012, NXT incurred foreign withholding taxes on a portion of its revenues that were generated in Latin and South America.  Although such foreign taxes paid can potentially be utilized in Canada as a foreign tax credit against future taxable earnings from the foreign jurisdictions, a full valuation allowance has been provided against this benefit.

Income tax expense is different from the expected amount that would be computed by applying the statutory Canadian federal and provincial income tax rates to NXT's income (loss) before income taxes as follows:

	2012			2011			2010
Net income (loss) before income taxes	$	2,489,149		$	(3,584,601	)	$	(4,452,428	)

The Company has significant unrecorded deferred income tax assets for which a full valuation allowance has been provided due to uncertainty regarding their potential utilization, as follows:

Net operating losses carried forward:
USA (expiration dates 2020 to 2026)	$	1,908,285		$	2,014,577		$	1,970,205

(i) On February 16, 2011 NXT closed a non-brokered private placement (the "2011 Placement") for aggregate proceeds of $1,600,300 ($1,487,827 net of costs incurred of $112,473) including $40,000 subscribed for by two Officers of the Company.  NXT issued a total of 3,200,600 units at a price of $0.50 per unit, with each unit consisting of one NXT common share and one warrant, with each warrant entitling the holder to acquire an additional common share at a price of $0.60 per share on or before the expiry date of February 16, 2012 (see also note 11).  In connection with closing of the 2011 Placement, NXT paid finder's fees which included $72,600 cash and 145,320 warrants, which had the same terms as the other warrants that were issued.

The common shares were recorded at a value equal to the net proceeds received of $1,488,267 and reduced by $329,386 which was the estimated fair value attributed to the 3,345,920 warrants that were issued in the 2011 Placement.

(ii) In March and May 2012, NXT conducted private placement financings (the "2012 Financings") which consisted of units issued at a price of US $0.75 (the "Units"). Each Unit consisted of one NXT common share and one warrant (the "Warrants") to purchase an additional NXT common share at a price of US $1.20. The Warrants have a term of two years from the date of issue, and the expiry can be accelerated at the option of NXT in the event that it issues a press release advising that its common shares have traded on the US OTCBB Exchange at a price exceeding US $1.50 for 20 consecutive trading days. Any Warrants subject to acceleration shall expire 30 days after such notice.

In connection with the 2012 Financings, NXT paid finder's fees totalling US $183,612 and issued a total of 244,816 finder's warrants (which have the same terms as the Warrants noted above).  The 2012 Financings had three separate closings in March, 2012 and one on May 4, 2012, which are summarized as follows:

	March,		May 4,
	2012		2012		total

		3,117,088		1,385,733		4,502,821

Two Officers of the Company subscribed for a total of US $40,000 of the 2012 Financings.

The common shares that were issued under the 2012 Financings were recorded at a value equal to the proceeds received of $3,183,132 ($2,886,024, net of related issue costs totalling $297,108), and reduced by $409,143 which was the estimated fair value attributed to the 4,502,821 Warrants that were issued (see also note 11).

PreferredShares

Preferred shares

The Company is authorized to issue an unlimited number of preferred shares, issuable in series.

In 2005, the Company issued 10,000,000 series 1 preferred shares (the "Preferred Shares") to its CEO pursuant to the execution of the Technical Transfer Agreement (see note 1) in exchange for the rights to utilize the SFD® technology for hydrocarbon exploration.

These Preferred Shares are non-voting, and are conditionally convertible into NXT common shares under the following terms:

● 2,000,000 of the Preferred Shares became convertible into common shares upon issue. In April 2013, the holder gave notice to NXT to formally convert (effective April 30, 2013) these 2,000,000 Preferred Shares into 2,000,000 common shares.

● The remaining 8,000,000 Preferred Shares are subject to conditions related to potential future conversion. They may become convertible into common shares in four separate increments of 2,000,000 Preferred Shares each, should NXT achieve specified cumulative revenue thresholds of US $50 million, US $100 million, US $250 million and US $500 million prior to December 31, 2015.

● An additional bonus of 1,000,000 Preferred Shares are issuable in the event that cumulative revenues exceed US $500 million.

● Cumulative revenue is defined as the sum of total revenue earned plus proceeds from the sale of assets accumulated since January 1, 2007, all denominated in United States dollars, and calculated in accordance with generally accepted accounting principles.

● In the event that the final cumulative revenue threshold of US $500 million is not achieved by December 31, 2015, NXT has the option to either redeem any remaining unconverted Preferred Shares for a price of $0.001 per share and forfeit its rights to the SFD® technology, or elect to retain the ownership of the SFD® technology by converting all of the remaining Preferred Shares into common shares.

The Preferred Shares do not participate in any dividends, and are not transferable except with the consent of the Board of Directors of NXT.

As at December 31, 2012, the Company had generated cumulative revenue of approximately US $23.1 million (December 31, 2011 - US $12.2 million) that is eligible to be applied to the above noted conversion thresholds.

The Preferred Shares were originally recorded at their estimated fair value as at December 31, 2005, with the total substantially assigned to the portion which was immediately convertible.  The remaining Preferred Shares were assigned a nominal value, reflecting the uncertainty that the required revenue objectives would be achieved to allow conversion into common shares, as follows:

	# of Preferred		recorded
	Shares		value
convertible upon issue effective December 31, 2005		2,000,000	$	3,256,400
conditionally convertible on or before December 31, 2015		8,000,000		232,600

Payments for this premises lease were $353,379 for the year ended December 31, 2012 (2011 - $347,130, 2010 - $358,642).

NXT currently does not own any of the aircraft which are used in its' survey operations, but has an annual agreement (which expires in January, 2014) to utilize a minimum annual volume of aircraft charter hours.  The contract has a minimum commitment of $317,000 for 2013.

In 2003 NXT was named as one of several defendants in a statement of claim related to an aircraft crash.  The plaintiffs alleged that all defendants were in breach of an aircraft ferry flight contract and were seeking damages of $450,000, but did not pursue their claim against NXT for over six years.  NXT was not a party to the contract and its position was that the claim was without merit.  The claim against NXT was discontinued in October 2012.
