Item 1. Business

Overview

We are an independent oil and gas exploration company with large prospects in offshore Republic of Guinea in Northwest Africa pursuant to rights granted to us by the government of Guinea (the "Concession") under a Hydrocarbon Production Sharing Contract, as amended ("PSC"). We sold a 40% gross interest in the Concession to Tullow Guinea Ltd. ("Tullow") in December 2012, and we now hold a 37% participating interest. Dana Petroleum, PLC ("Dana"), a subsidiary of the Korean National Oil Corporation, holds the remaining 23% interest in the Concession. Tullow became the Operator of the Concession on April 1, 2013. We refer to Tullow, Dana and us in the Concession as the "Consortium".

Since the grant of the Concession in 2006, one well has been drilled and it was non-commercial. The Consortium plans to commence drilling a deepwater exploration well in the first quarter of calendar 2014.

We have conducted 2-dimensional ("2D") and 3-dimensional ("3D") surveys of a portion of the Concession. The acquisition phase of the most recent 3D seismic survey covering approximately 4,000 square kilometers in the deeper water portion of the Concession was completed by the CGG Veritas Ocean Endeavor in January 2012 and processing is near completion. The initial products from the prestack time migration was received in January 2013. The cost for acquiring the survey, processing and other services is expected to total approximately $27.7 million gross. Of these estimated costs, the Consortium has incurred approximately $27.5 million on a gross basis as of June 30, 2013.

Our primary focus is the advancement of exploration work in Guinea. We also plan to continue to evaluate and consider other global oil and gas opportunities. We have no source of operating revenue, and there is no assurance when we will, if ever. We have no operating cash flows, and we will require substantial additional funds, through additional participants, securities offerings, or through other means, to fulfill our business plans.

Our executive offices are located at 12012 Wickchester Lane, Suite 475, Houston, Texas 77079, and our telephone number is (713) 353-9400.

OPERATIONS OFFSHORE GUINEA

The PSC

We have been conducting exploration work related to offshore Guinea since 2002. On September 22, 2006, we, acting through our wholly owned subsidiary, SCS Corporation Ltd ("SCS"), entered into the PSC with Guinea. Under that agreement, we were granted certain exclusive contractual rights by Guinea to explore and exploit offshore oil and gas reserves, if any, off the coast of Guinea. We refer to the rights to the offshore area subject to the Concession as the "Contract Area."

On March 25, 2010, we entered into Amendment No. 1 to the PSC with Guinea (the "PSC Amendment"). In May 2010, the government of Guinea issued a Presidential Decree approving the PSC, as amended by the PSC Amendment. The PSC Amendment clarified that we retained a Contract Area of approximately 25,000 square kilometers, which is approximately equivalent to 9,650 square miles or 30% of the original Contract Area under the PSC. The PSC Amendment requires that an additional 25% of the retained Contract Area be relinquished by September 21, 2013. Under the terms of the PSC Amendment, the first exploration period ended and the second exploration period began on September 21, 2010. The second exploration period runs until September 2013, may be renewed to September 2016 and may be extended for one additional year to allow the completion of a well in process and for two additional years to allow the completion of the appraisal of any discovery made. The Consortium sent a notice to the Government of Guinea to renew the second exploration period to September 2016. The notice included the coordinates of the area to be relinquished.

The PSC Amendment required the drilling of an exploration well, which had to be commenced by year-end 2011, and drilled to a minimum depth of 2,500 meters below seabed. This requirement was satisfied with the drilling of the Sabu-1 well which was commenced during October of 2011 and reached the minimum depth of 2,500 meters below the seabed in February of 2012. It also required the acquisition of at least 2,000 square kilometers of 3D seismic data which was satisfied by the 3,600 square kilometer seismic acquisition in 2010-2011. To satisfy the September 2013-2016 work requirement, the Consortium is required to commence drilling of an additional exploration well by the end of September 2016, to a minimum depth of 2,500 meters below seabed. The PSC Amendment requires the expenditure of $15 million on each of the exploration wells ($30 million in the aggregate). Greater than $15 million was spent on the first exploration well, and it is expected the cost of the next exploration well will be significantly greater than $15 million.

Fulfillment of work obligations exempts us from expenditure obligations, and exploration work in excess of minimum work obligations for each exploration period may be carried forward to the following exploration period.

Under the PSC Amendment, Guinea may participate in development of any discovery at a participating interest of up to 15% of costs being carried for its share. The cost of that carry is to be recovered out of 62.5% of Guinea's share of cost and profit oil. The PSC Amendment removed the right of first refusal covering the relinquished acreage under the original PSC. The PSC Amendment clarified that only those eligible expenditures, which were made following the date the PSC was signed, on September 22, 2006, are eligible for cost recovery. It requires the establishment of an annual training budget of $200,000 for the benefit of Guinea's oil industry personnel, and also obligates the Consortium to pay an annual surface tax of $2.00 per square kilometer on the retained Concession acreage. The PSC Amendment also provides that should the Guinea government note material differences between provisions of the PSC Amendment and international standards or the Petroleum Code, the parties will renegotiate the relevant articles.

In July of 2013, a proposal was submitted for a Second Amendment to the PSC (the "Second PSC Amendment") to the Government of Guinea formally adding Tullow as a Contractor to the PSC as well as addressing other administrative issues.

Sale of Interest to Dana

On December 4, 2009, SCS entered into a Sale and Purchase Agreement ("SPA") with Dana for Dana to acquire a 23% gross interest in the PSC. On January 28, 2010, we closed on the transaction with Dana, and we entered into an Assignment of Participating Interest (the "Assignment"), a Deed of Assignment and Joint Operating Agreement ("JOA"). Pursuant to the Assignment, we assigned to Dana an undivided 23% of our participating interest in the contractual interests, rights, obligations and duties under the PSC. As required by the PSC, the Deed of Assignment was delivered as the necessary notice of the Assignment to be given to the Guinean government. In May 2010, we received an administrative order from the Ministry of Mines and Geology of Guinea, referred to as an arrêté, confirming the Guinea government's approval of the assignment of a 23% participating interest in the PSC to Dana.

Sale of Interest to Tullow

On December 31, 2012, our wholly owned subsidiary, SCS, closed a sale to Tullow of a 40% gross interest in the Concession. As consideration, SCS received $27 million from Tullow as reimbursement of past costs of SCS in the Concession and, as additional consideration, Tullow agreed to: (i) pay SCS's participating interest share of future costs associated with the drilling of an exploration well in at least 2,000 meters of water in the deep water fan area of the Concession, up to a gross expenditure cap of $100 million; and (ii) pay SCS's share of costs associated with an appraisal well of the initial exploration well, if drilled, subject to a gross expenditure cap on the appraisal well of $100 million. Tullow is obligated to pay its 40% participating interest share of costs associated with the Concession as of November 20, 2012, the date of execution of the purchase and sale agreement. Tullow will begin to pay SCS's costs attributable to the Concession at the earlier of (i) the commencement of the next exploration period, September 21, 2013, or (ii) should a decision be made to begin spending on an exploration well prior to committing to the next exploration period, the date of such spending. Tullow will continue to pay SCS's costs, subject to the gross expenditure cap of $100 million, until 90 days following the date on which the rig contracted to drill the exploration well moves off the well location. Tullow agreed to use reasonable endeavors to provide for the commencement of drilling of the exploration well not later than April 1, 2014. The $27 million payment was received by us on December 31, 2012 and was recorded as a reduction in unproved oil and gas properties, net of transaction costs of approximately $3.3 million.

In connection with the transaction, SCS, Tullow and Dana entered into a Joint Operating Agreement Novation and Amendment Agreement reflecting that as a result of the sale to Tullow, the interests in the Concession are SCS 37%, Dana 23%, and Tullow 40%. The Amendment also provides for Tullow to be bound by the PSC and the Joint Operating Agreement previously entered into between SCS and Dana, and for Tullow to assume all the respective liabilities and obligations of SCS in respect of the assigned 40% interest. SCS and Tullow executed a Deed of Assignment. The Assignment was approved by Guinea's Ministry of Mines and Geology by issuing an Arrêté on December 27, 2012 which formally authorized our assignment of a participating interest to Tullow. SCS, Dana and Tullow elected Tullow as the Operator of the Concession beginning April 1, 2013.

Exploration Strategies and Work to Date

Our business plan incorporates a multi-channel approach to exploring and developing our Contract Area under the PSC. We plan to continue to develop and evaluate drilling targets and complete technical work and planning with Tullow and Dana. We have completed the acquisition phase of the most recent 3D seismic survey covering approximately 4,000 square kilometers on our Contract Area. Processing of the most recent 3D data set is near completion. This most recent 3D survey allows us to study Upper Cretaceous submarine fan structures along the Transform Margin trend of Guinea.

Table of Contents

From the inception of our involvement in Guinea beginning in 2002 through June 2009, we accomplished exploration work, including:

•: a 1,000 kilometer 2D seismic data shoot, the processing of the seismic data acquired, and the evaluation of that data and data that had been acquired in the past;
•: a 4,000 kilometer 2D seismic data shoot, the processing of the seismic data acquired, and the evaluation of that data and data that had been acquired in the past;
•: acquisition and geochemical analysis of core samples from the Contract Area and a satellite seeps study;
•: third party interpretation and analysis of our seismic data, performed by PGS;
•: reconnaissance within Guinea to evaluate drilling infrastructure, support services, and the operating environment;
•: a 2,800 kilometer 2D seismic data shoot, the processing of the seismic data acquired, and the evaluation of that data and data that had been acquired in the past;

Since July 2009, we have accomplished critical exploration work, including:

•: an oil seep study performed by TDI Brooks;
•: a 10,400 kilometer 2D seismic data shoot, the processing of the seismic data acquired, and the evaluation of that data;
•: a 3,635 square kilometer 3D seismic data shoot covering the shallower-water portion of the deep water area, and the processing of the seismic data acquired, and the evaluation of that data;
•: completion of the drilling of the Sabu-1, an exploratory well, and evaluation of associated core and fluid samples; and
•: a 4,000 square kilometer 3D seismic data shoot primarily covering the deeper water area, and the continuing processing and evaluation of the seismic data acquired.

CGG Veritas

The acquisition phase of the most recent 3D seismic survey covering approximately 4,000 square kilometers in the deeper water portion of the Concession (referred to as Survey C) was completed by the CGG Veritas Ocean Endeavor in January 2012. Processing of the most recent 3D data set is near completion. The cost for acquiring the survey, processing and other services is expected to total approximately $27.7 million gross. Of these estimated costs, the Consortium has incurred approximately $27.5 million on a gross basis as of June 30, 2013.

AGR Peak Well Management Limited

We contracted with AGR Peak Well Management Limited ("AGR") to manage our exploration drilling project in offshore Republic of Guinea and to handle well construction project management services, logistics, tendering and contracting for materials as well as overall management responsibilities for the drilling program. The Sabu-1 well was drilled under this contract. The cost incurred on the Sabu-1 well was significantly higher than expected. On June 21, 2012, our wholly-owned subsidiary, SCS, filed suit against AGR following unsuccessful negotiations to address project management that led to cost overruns associated with the Sabu-1 well.

DESCRIPTION OF OIL AND GAS PROPERTIES

The Contract Area is located in the Transform Margin play, offshore Guinea. The Consortium has the exclusive exploration and production rights to explore and develop approximately 25,000 square kilometers in offshore Guinea (see map below) under the Concession. We have satisfied all requirements of the current exploration period, which runs until September 2013 under the Concession. The Consortium sent notice to the Government of Guinea of our intention to renew the second exploration period to September 2016 and the coordinates of the area to be relinquished as required under the PSC. The second exploration period may be extended for one additional year beyond 2016 to allow the completion of a well in process and for two additional years to allow the completion of the appraisal of any discovery made. Additionally, to satisfy the September 2013-2016 work requirement, an additional exploration well is required to be drilled, which is to be commenced by the end of September 2016, to a minimum depth of 2,500 meters below seabed. The Consortium plans to commence the drilling of a deepwater exploration well during the first quarter of calendar 2014, which would satisfy the requirement to drill in the second exploration period. Tullow has agreed to pay SCS's participating interest share of future costs associated with the drilling of this well, up to a gross expenditure cap of $100 million. Additionally, Tullow has agreed to pay SCS's participating interest share of future costs associated with the drilling of an appraisal of the initial exploration well, if drilled, up to a gross expenditure cap of $100 million. We are responsible for our share of any costs exceeding the gross expenditure cap of $100 million on either well.

Our prospects are in an underexplored basin among multiple highly prospective trends with multiple play types: Turbidite fans, 4-way closures and Neocomian-age Carbonates.

Two wells have been drilled in the Contract Area: the GU-2B-1 well (1977) and the Sabu-1 well (2012). The GU-2B-1 well was drilled by another company in 100 meters of water reaching a total depth of 3,353 meters below sea level. Drilling of the Sabu-1 well was finished in February 2012 in 710 meters of water with the Jasper Explorer Drillship reaching a total depth of 3,601 meters below sea level.

Table of Contents

The GU-2B-1 well drilled in 1977 demonstrated good Upper Cretaceous shelf reservoirs and source rock. The oil seep and oil slick evaluation done by us in 2009 indicated a working petroleum system with mature Upper Cretaceous marine source. Well data from the Sabu-1 well also confirmed to us the presence of a working petroleum system. Hydrocarbons in fluid inclusions in the rock drilled in the well demonstrate that the well was part of an oil-migration pathway, and oil and gas shows during drilling of the well indicate the presence of hydrocarbons in the upper Cretaceous section. Our well-log interpretations indicated residual oil (noncommercial oil saturations) in a 400-meter section of the Upper Cretaceous. The fluid sampling of Upper Cretaceous intervals did not find movable oil. We believe the Sabu-1 well was not a commercial success because of the lack of a reservoir seal such as marine shales or reservoir-seal pairs needed for a commercial accumulation.

The Concession is covered by approximately 18,200 kilometers of 2D seismic acquired by us and 7,635 square kilometers of 3D seismic (with 4,000 square kilometers acquired during fiscal 2012 in the deepwater portion of the block). The most recent 3D seismic (Survey C), currently being interpreted, shows thick wedges of sediment that may contain deep water sandstone reservoirs with marine shale seals which can trap significant oil accumulations, similar to recent discoveries by others on trend. We believe the Sabu-1 well results, demonstrating good reservoir and a working petroleum system, reduce the risks associated with the deeper water exploration program and support the possibility of a continuation into Guinea of the oil-prone play along the Equatorial Atlantic margin.

Multiple discoveries have been made by other companies along the Equatorial Atlantic margin (the Transform Margin play), extending from Ghana to Sierra Leone and now possibly into Guinea. In addition, the Central North Atlantic margin of northwest Africa, located to the north, appears to continue southward into offshore Guinea and the northern portion of the PSC. Current industry interest in the Central North Atlantic margin, indicated by active exploration programs along that margin from Mauritania through Senegal and Guinea Bissau, suggests to us additional exploration potential for the northern portion of the Concession.

We intend to work with other members of the Consortium to interpret the 3D seismic survey over the deep water fan trend and analyze the Sabu-1 well data to initiate a new drilling program.

Reserves Reported To Other Agencies

We have not reported any estimates of proved or probable net oil or gas reserves to any federal authority or agency since July 1, 2008, on producing properties owned in the United States at that time, but subsequently sold in 2009.

Production

As a result of the 2009 sale of our oil and gas operations located in the United States, we currently have no producing properties and have had no production during the years covered by these financial statements.

Delivery Commitments

We currently have no existing contracts or agreements obligating us to provide a fixed or determinable quantity of oil or gas in the future.

Employees and Independent Contractors

As of September 5, 2013, we have 20 full time employees, all of whom are based in the United States. We also use independent contractors from time to time for specific projects. No employees are represented by a union.

Table of Contents

Competition

Many companies and individuals engage in drilling for gas and oil, and there is competition for the most desirable prospects. We expect to encounter intense competition from other companies and other entities in the sale of our oil and gas. We could be competing with numerous oil and gas companies which may have financial resources significantly greater than ours.

Productive Wells and Acreage; Undeveloped Acreage

We currently do not have any productive oil or gas wells, and we do not have any developed acres (i.e. acres spaced or assignable to productive wells). The following table sets forth undeveloped acreage that we held as of June 30, 2013:

	Undeveloped Acreage(1)(2)

	Gross Acres		Net Acres
*Foreign*
Offshore Guinea		6,176,000		2,285,120

Total(3)		6,176,000		2,285,120

(1): A gross acre is an acre in which a working interest is owned. A net acre is deemed to exist when the sum of fractional ownership working or participation interests in gross acres equals one. The number of net acres is the sum of the fractional working interests owned in gross acres expressed as whole numbers and fractions thereof. Undeveloped acreage is considered to be those leased acres on which wells have not been drilled or completed to a point that would permit the production of commercial quantities of crude oil and natural gas regardless of whether or not such acreage contains proved reserves.
(2): One square mile equals 640 acres. The Contract Area in the Concession is approximately 25,000 square kilometers, or 9,650 square miles. We have a 37% working interest in the Concession.
(3): The PSC requires that 25% of the retained Contract Area be relinquished by September 2013. The Consortium sent a notice to the Government of Guinea to renew the second exploration period to September 2016. The notice included the coordinates of the area to be relinquished.

Drilling Activity

An exploratory well is a well drilled to find and produce crude oil or natural gas in an unproved area, to find a new reservoir in a field previously found to be productive of crude oil or natural gas in another reservoir, or to extend a known reservoir. A development well is a well drilled within the proved area of a crude oil or natural gas reservoir to the depth of a stratigraphic horizon known to be productive.

In October 2011, we commenced drilling operations on the Sabu-1 well. In February 2012, the Sabu-1 exploratory well reached the planned total depth of 3,600 meters.

Table of Contents

The following table sets forth the results of our drilling activities during the three years ended June 30, 2013:

Geographical Information

The following table sets out long-lived assets associated with Guinea, including our investment in the Concession offshore Guinea as well as fixed assets:

		June 30, 2013			June 30, 2012			June 30, 2011

Long-lived assets related to Guinea		$	21,174,000		$	39,617,000		$	36,716,000

The seismic data we collected prior to Tullow becoming Operator and our geological and geophysical work product are maintained in our offices in the United States. The June 30, 2013 amount of $20.2 million is net of $116.8 million of costs which were fully amortized though our Full-Cost Ceiling Test as a result of the Sabu-1 exploratory well being non-commercial. Additionally, the $27.0 million net of transaction costs of approximately $3.3 million received from Tullow in the sale of a 40% participating interest was also recorded as a reduction in our June 30, 2013 carrying value of the Concession.

Cost of Compliance with Environmental Laws

Environmental laws have not materially hindered nor adversely affected our business. Capital expenditures relating to environmental control facilities have not been prohibitive to our operations. We believe we are in compliance with all applicable environmental laws.

Item 1A. Risk Factors

An investment in our common stock involves significant risks. Prior to making a decision about investing in common stock, and in consultation with your own financial and legal advisors, you should carefully consider, among other matters, the following risk factors. The risks and uncertainties described below are not the only ones facing us. Additional risks and uncertainties not presently known to us or that we currently consider immaterial may also inadvertently affect us. If any of the following risks occur, our business, financial condition or results of operations could be materially harmed.

Risks Relating to Our Business and the Industry in Which We Operate.

Our business is dependent on a single exploration asset.

The Concession is currently our single exploration asset. We have been conducting exploration work related to offshore Guinea since 2002, including significant seismic data surveys, processing, evaluations and studies, but we have no proved reserves and there is no assurance that our exploration work will result in any discoveries or in any commercial success. The PSC requires the drilling of a minimum of one additional exploration well to a minimum depth of 2,500 meters below the seabed at a minimum cost of $15 million by September 21, 2016. The PSC has other work and additional obligations that need to be performed to maintain compliance with the PSC. Failure to comply could subject us to risk of loss of the Concession. In addition, oil and natural gas operations in Africa may be subject to higher political and security risks than operations in the United States. Any adverse development affecting our operations such as, but not limited to, the drilling and operational hazards described below, could result in damage to, or destruction of, any wells and producing facilities constructed on the Concession as well as damage to life. As the Concession is our only exploration asset, any adverse development affecting it could have a material adverse effect on our financial position and results of operations.

We have no proved reserves and our exploration program may not yield oil in commercial quantities or quality, or at all.

We have no proved reserves. We have drilled one exploratory well which had non-commercial results. We, and other members of the Consortium, have identified leads based on seismic and geological information that indicate the potential presence of oil. However, the areas to be drilled may not yield oil in commercial quantities or quality, or at all. Even when properly used and interpreted, 2D and 3D seismic data and visualization techniques are only tools used to assist geoscientists in identifying subsurface structures and hydrocarbon indicators and do not enable the interpreter to know whether hydrocarbons are, in fact, present in those structures. Accordingly, we do not know if any of our prospects will contain oil in sufficient quantities or quality to recover drilling and completion costs or to be economically viable. Even if oil is found in commercial quantities, construction costs of oil pipelines or floating production systems, as applicable, and transportation costs may prevent such leads from being economically viable. If these exploration efforts do not prove to be successful, our business, financial condition and results of operations will be materially adversely affected.

The recent sale of part of our interest in the Concession offshore Guinea improved our liquidity and financial condition, but our capital resources continue to be limited. Our liquidity will be strained if drilling cost estimates are exceeded, and we may need new funding for additional exploration in the Concession, the availability of which is unknown.

We received $27 million in December 2012 at closing of the sale to Tullow of a 40% gross interest in the Concession, which has improved our liquidity and financial condition. In addition, Tullow agreed to make payments for our participating share (37%) of the costs in connection with the drilling of a deep water exploration well and, if drilled, an appraisal well in respect of such deep water exploration well. However, for each well there is a gross expenditure cap of $100 million. Drilling in deep water is expensive, and cost overruns often occur. If costs for the initial deep water well, or the appraisal well (if drilled), are greater than the amount agreed to be paid by Tullow, we will be responsible for these costs. Our current capital resources are limited and may not be sufficient.

Additional exploration activity in the Concession, including additional seismic surveys or the drilling of additional wells, would likely require that we obtain additional funding to pay for our share of such costs. We may seek such funding through additional sales of interest in the Concession, from equity or debt financings, or through other means. We have no commitments for additional funding, and if obtained, the terms may not be advantageous to us.

We will need additional funding to drill additional wells. Efforts to attract commercial partners may not be successful and may not be on terms advantageous to us.

The December 2012 sale to Tullow improved our cash position and liquidity, and we have adequate funds to conduct our current operations. However, we have no source of operating revenue and our ability to drill additional wells will depend on obtaining additional resources through sales of additional interests in the Concession, equity or debt financings, or through other means. If we seek to sell additional interests in the Concession, we may not be successful in attracting a commercial partner, or the commercial partner may not have the capital resources or other attributes that are deemed desirable by us. If we enter into an arrangement, the terms may not be advantageous to us. Any such arrangement will likely involve the transfer of a negotiated interest in the Concession, which could reduce the potential profitability of our interest in the Concession.

We may not be able to obtain the additional capital necessary to achieve our business plan.

Our business is capital intensive, and we must invest a significant amount in our activities. We intend to make substantial capital expenditures to find, develop and produce natural gas and oil reserves.

Additional capital could be obtained from a combination of funding sources. The current potential funding sources and the potential adverse effects attributable thereto, include:

•: sales or assignments of interests in the Concession and exploration program, which would reduce any future revenues from that program while at the same time offsetting potential expenditures;
•: offerings of equity, equity-linked and convertible debt securities, which would dilute the equity interests of our stockholders;
•: debt and convertible debt offerings, which would increase our leverage and add to our need for cash to service such debt and which could result in assets being pledged as collateral; and
•: borrowings from financial institutions, which may subject us to certain restrictive covenants, including covenants restricting our ability to raise additional capital or pay dividends.

Table of Contents

It is difficult to quantify the amount of financing we may need to fund our business plan in the longer term. The amount of funding we may need in the future depends on various factors such as:

•: our financial position;
•: the cost of exploration and drilling;
•: the prevailing market price of natural gas and oil; and
•: the lead time required to bring any discoveries to production.

While we believe we have sufficient resources to fund the next exploratory well and working capital for at least the next 12 months, additional capital will likely be required beyond this period. If we do not obtain capital resources in the future it is unlikely that we would be able to continue to pursue exploration offshore Guinea and our financial condition and operations would be adversely affected.

As a result of our recent sale, we do not own a majority interest in the Concession, and we are not the Operator. We have significantly less influence regarding the timing of exploration and development activities, associated budgets and costs, and other operational decisions.

As a result of the sale to Tullow in December 2012, our interest in the Concession was reduced from 77% to 37%. The transfer of operatorship to Tullow was completed in April 2013. The Joint Operating Agreement (JOA) that governs the Concession provides significant authority to the Operator. The JOA also requires certain actions to be approved by at least 67% of the interests. In the future, we will have less ability to influence operations, including the timing of exploration and development activities, the amount of capital expenditures, and other material operating decisions. The reduced ability to influence operations may cause a material adverse effect on our financial condition and results of operations.

The PSC is subject to renegotiation under certain conditions, which may have an adverse impact upon our operations and profitability.

The PSC provides that should the Guinea government note material differences between provisions of the PSC and international standards or the Guinea Petroleum Code, the parties will renegotiate the relevant articles of the PSC. If the Guinea government identifies material differences between the PSC's provisions and international standards or the Guinea Petroleum Code, there is no assurance that we will be able to negotiate an acceptable modification to the PSC. If the parties are not successful in renegotiating the relevant articles of the PSC, the parties may be required to submit the matter to international arbitration. There is no assurance that any arbitration would be successful or otherwise lead to articles that are more favorable to us than the present articles. Therefore, the results of such negotiations or arbitration could be unfavorable to us and, as a result, could have a material adverse effect on our business, financial position, results of operation and future cash flows.

We are highly dependent on our management team and consultants, and any failure to retain the services of such parties could adversely affect our ability to effectively manage our operations or successfully execute our business plan.

Our business is dependent on retaining the services of a small number of key personnel of the appropriate caliber as the business develops. Our success is, and will continue to be to a significant extent, dependent upon the expertise and experience of the directors, senior management and certain key personnel. While we have entered into contractual arrangements with the aim of securing the services of the key management team, the retention of their services cannot be guaranteed. The loss of key members of our management team or other highly qualified technical professionals could adversely affect our ability to effectively manage our overall operations or successfully execute current or future

business strategies. If any member of management or director were to leave our company, it may have a material adverse effect on our business, financial condition, results of operations and/or growth prospects.

We have claims and lawsuits against us that may result in adverse outcomes.

We are subject to a variety of claims and lawsuits concerning shareholder claims and other matters. Adverse outcomes in some or all of these claims may result in significant monetary damages or limit our ability to engage in our business activities. While we have director and officer insurance, it may not apply to or fully cover any liabilities we incur as a result of these lawsuits. Although management currently believes resolving all of these matters, individually or in the aggregate, will not have a material adverse impact on our financial statements, the litigation and other claims are subject to inherent uncertainties and management's view of these matters may change in the future. A material adverse impact on our financial statements also could occur for any period it was determined that an unfavorable final outcome is probable and reasonably estimable.

An inability to resolve the legal dispute with AGR could adversely affect our consolidated results of operations and liquidity.

Our wholly-owned subsidiary, SCS, has a pending lawsuit against AGR following unsuccessful negotiations to address project management issues that we believe led to the cost overruns associated with the Sabu-1 well. Although management believes this matter will not have a material adverse impact on our consolidated results of operations, the litigation and other claims are subject to inherent uncertainties and management's view of these matters may change in the future. On October 1, 2012, AGR filed a defense denying SCS's allegations and asserting a net counterclaim for $22.2 million which AGR alleges to be the outstanding amount owed on the Sabu-1 drilling project, and seeking other unspecified damages and relief, including damages for loss of management time and associated expenses, a full indemnity for a claim brought by Jasper against AGR, and interest on any damages awarded. SCS filed a reply to AGR's defense on December 3, 2012 and responded by denying AGR's counterclaim. Resolution of this dispute may result in the recovery by us of a portion of the costs incurred to date but an adverse outcome in this dispute may result in significant additional liability and may negatively impact our consolidated results of operations and liquidity.

Drilling wells is speculative and potentially hazardous. Actual costs may be more than our estimates, and may not result in any discoveries. The cost of our recently drilled exploratory well was significantly higher than expected.

Exploring for and developing oil reserves involves a high degree of operational and financial risk, which precludes definitive statements as to the time required and costs involved in reaching certain objectives. The budgeted costs of drilling, completing and operating wells are often exceeded. The cost of our recently drilled exploratory well, the Sabu-1, was higher than we initially expected, primarily due to numerous delays and issues related to mechanical and operational matters on the rig, logistical delays resulting from limited port facilities in Guinea, and an expanded well logging program. In addition, oil was not discovered in commercial quantities. Unexpected delays and increases in costs associated with wells drilled in the future, could adversely affect our results of operation, financial position, liquidity and business plans.

Drilling may be unsuccessful for many reasons, including geological conditions, weather, cost overruns, equipment shortages and mechanical difficulties. Exploratory wells bear a much greater risk of loss than development wells. The successful drilling of an oil well may not be indicative of the potential for the development of a commercially viable field and will not necessarily result in a profit on investment. A variety of factors, both geological and market-related, can cause a well to become uneconomic or only marginally economic.

Table of Contents

There are a variety of operating risks, including:

•: blowouts, cratering and explosions;
•: mechanical and equipment problems;
•: uncontrolled flows of oil and gas or well fluids;
•: fires;
•: marine hazards with respect to offshore operations;
•: formations with abnormal pressures;
•: pollution and other environmental risks; and
•: weather conditions and natural disasters.

Offshore operations are subject to a variety of operating risks particular to the marine environment, such as capsizing and collisions. Also, offshore operations are subject to damage or loss from adverse weather conditions. Any of these events could result in loss of human life, significant damage to property, environmental pollution, impairment of our operations and substantial losses.

The site for the exploratory well the Consortium plans to drill in the first quarter of calendar 2014 has not been finalized; however, it has been agreed that the next well will be in deep water. Deepwater drilling generally requires more time and more advanced drilling technologies than exploration in shallower waters, involving a higher risk of equipment failure and usually higher drilling costs. In addition, there may be production risks of which we are currently unaware. If we participate in the development of new subsea infrastructure and use floating production systems to transport oil from producing wells, these operations may require substantial time for installation or encounter mechanical difficulties and equipment failures that could result in significant liabilities, cost overruns or delays. Furthermore, deepwater operations generally, and operations in West Africa in particular, lack the physical oilfield service infrastructure present in other regions. As a result, a significant amount of time may elapse between a deepwater discovery and the marketing of the associated oil and natural gas, increasing both the financial and operational risks involved with these operations. Because of the lack and high cost of this infrastructure, further discoveries the Consortium may make in Guinea may never be economically producible.

We have no ability to control the prices that we may receive for oil or gas. Oil and gas prices are volatile, and a substantial or extended decline in prices could adversely affect our financial condition, liquidity, ability to obtain financing and future operating results.

We currently have no source of operating revenue. Our financial condition is based solely on our ability to sell equity or debt securities to investors, enter into an additional joint operating or similar strategic relationship with an industry partner, sell interests related to the Concession or borrow funds. We expect that entering into these joint operating or similar relationships would entail transferring a portion of our interest in the Concession to such partner. Such investors would consider the price of oil and gas in making an investment decision. Declines in oil and gas prices may adversely affect our financial condition, liquidity, ability to obtain financing and operating results. Low oil and gas prices also may reduce the amount of oil and gas that we could produce economically. Low oil and gas prices in the future could have a negative effect on our future financial results. Historically, oil and gas prices and markets have been volatile, with prices fluctuating widely, and they are likely to continue to be volatile. Prices for oil and gas are subject to wide fluctuations in response to relatively minor changes in supply and demand, market uncertainty and a variety of additional factors that are beyond our control. These factors include:

•: the level of domestic and foreign supplies of oil;

Table of Contents

•: the level of consumer product demand;
•: weather conditions and natural disasters;
•: political conditions in oil producing regions throughout the world;
•: the ability of the members of the Organization of Petroleum Exporting Countries to agree to and maintain oil production;
•: speculation as to the future price of oil and natural gas and the speculative trading of oil and natural gas futures contracts;
•: price and production controls;
•: political and economic conditions, including embargoes in oil-producing countries or affecting other oil-producing activities, particularly in the Middle East, Africa, Russia and South America;
•: continued threat of terrorism and the impact of military and other action, including U.S. military operations in the Middle East;
•: the level of global oil and natural gas exploration and production activity;
•: the price of foreign oil imports;
•: actions of governments;
•: domestic and foreign governmental regulations;
•: the price, availability and acceptance of alternative fuels;
•: technological advances affecting energy consumption;
•: global economic conditions; and
•: the value of the U.S. dollar, the Euro and fluctuations in exchange rates generally.

These factors and the volatile nature of the energy markets make it impossible to predict oil and gas prices. Our inability to respond appropriately to changes in these factors could have a material adverse effect on our business plan, financial position, results of operations and future cash flows.

The unavailability or high cost of drilling rigs, equipment, supplies, personnel and oilfield services, as well as gathering systems and processing facilities, and our dependence on the operator and on industry contractors generally, could adversely impact us.

We are dependent on the operator and on industry contractors for the success of our oil and gas exploration projects. In particular, our drilling activity offshore of Guinea will require that we have access to offshore drilling rigs and contracts with experienced operators of such rigs. The availability and cost of drilling rigs and other equipment and services, and the skilled personnel required to operate those rigs and equipment is affected by the level and location of drilling activity around the world. An increase in drilling operations worldwide may reduce the availability and increase the cost to us of drilling rigs, other equipment and services, and appropriately experienced drilling contractors. The reduced availability of such equipment and services may delay our ability to discover reserves and higher costs for such equipment and services may increase our costs, both of which may have a material adverse effect on our business, results of operations and future cash flow. If we succeed in constructing oil wells, we may be required to shut them because access to pipelines, gathering systems or processing facilities may be limited or unavailable. If that were to occur, we would be unable to realize revenue from those wells until arrangements were made to deliver the production to market, which could cause a material adverse effect on our results of operations and financial condition.

Table of Contents

We are exposed to the failure or non-performance of commercial counterparties.

Our operations will be dependent on certain third parties with whom we have commercial agreements (such as drilling contractors and the parties responsible for transporting and/or storing our production) for our future exploration, development, production, sales or other activities. The efficiency, timeliness and quality of contract performance by third party providers are largely beyond our direct control. If one or more of these third parties fails to meet its contractual obligations to us, or if such services are temporarily or permanently unavailable (for example, as a result of technical problems or industrial action), or not available on commercially acceptable terms, we may experience a material adverse effect on our business, results of operations, financial condition and future cash flow. In addition, as a named party under the PSC, we could be held liable for the environmental, health and safety impacts arising out of the activities of our drilling project management contractor or any other third party service provider contracted by us or on our behalf, which could have a material adverse effect on our business, results of operations and future cash flow.

Participants in the oil and gas industry are subject to numerous laws that can affect the cost, manner or feasibility of doing business.

Exploration and production activities in the oil and gas industry are subject to local laws and regulations. We may be required to make large expenditures to comply with governmental laws and regulations, particularly in respect of the following matters:

•: licenses for drilling operations;
•: tax increases, including retroactive claims;
•: unitization of oil accumulations;
•: local content requirements (including the mandatory use of local partners and vendors); and
•: environmental requirements and obligations, including investigation and/or remediation activities.

Under these and other laws and regulations, we could be liable for personal injuries, property damage and other types of damages. Failure to comply with these laws and regulations also may result in the suspension or termination of our operations and subject us to administrative, civil and criminal penalties. Moreover, new laws and regulations may be enacted and current laws and regulations could change or their interpretations could change, in ways that could substantially increase our costs. These risks may be higher in the developing countries in which we conduct our operations, where there could be a lack of clarity or lack of consistency in the application of these laws and regulations. Any resulting liabilities, penalties, suspensions or terminations could have a material adverse effect on our financial condition and results of operations.

Furthermore, the explosion and sinking in April 2010 of the Deepwater Horizon oil rig during operations on the Macondo exploration well in the Gulf of Mexico, and the resulting oil spill, may have increased certain of the risks faced by those drilling for oil in deepwater regions, including increased industry standards, governmental regulation and enforcement, and less favorable investor perception of the risk-adjusted benefits of deepwater offshore drilling.

The occurrence of any of these factors, or the continuation thereof, could have a material adverse effect on our business, financial position or future results of operations.

We may not be able to commercialize our interests in any natural gas produced from our Guinea Concession.

The development of the market for natural gas in West Africa is in its early stages. Currently there is no infrastructure to transport and process natural gas on commercial terms in Guinea, and the expenses associated with constructing such infrastructure ourselves may not be commercially viable given local prices currently paid for natural gas. Accordingly, there may be limited or no value derived from any natural gas produced from our Guinea Concession.

Table of Contents

Our insurance coverage may be insufficient to cover losses, or we could be subject to uninsured liabilities which could materially affect our business, results of operations or financial condition.

There are circumstances where insurance will not cover the consequences of an event, or where we may become liable for costs incurred in events or incidents against which we either cannot insure or may elect not to have insured (whether on account of prohibitive premium costs or for other commercial reasons). Further, insurance covering certain matters (such as sovereign risk, terrorism and many environmental risks) may not be available to us. Moreover, we may be subject to large excess payments in the event a third party has a valid claim against us, and therefore may not be entitled to recover the full extent of our loss, or may decide that it is not economical to seek to do so. The realization of any significant liabilities in connection with our future activities could have a material adverse effect on our business, results of operations, financial condition and future cash flow.

There are risks associated with the drilling of oil and natural gas wells which could significantly reduce our revenues or cause substantial losses, impairing our future operating results. We may become subject to liability for pollution, blow-outs or other hazards, including those arising out of the activities of our third-party contractors. We intend to obtain insurance with respect to certain of these hazards, but such insurance likely will have limitations that may prevent us from recovering the full extent of such liabilities. The payment by us of such liabilities could reduce the funds available to us or could, in an extreme case, result in a total loss of our properties and assets. Moreover, oil and natural gas production operations are also subject to all the risks typically associated with such operations, including premature decline of reservoirs and the invasion of water into producing formations.

We have competition from other companies that have larger financial and other resources than we do, which puts us at a competitive disadvantage.

A large number of companies and individuals engage in drilling for gas and oil, and there is competition for the most desirable prospects. We are likely to face competition from international oil and gas companies, which already may have significant operations in a region, together with potential new entrants into such markets, any of which may have greater financial, technological and other resources than us. There is a high degree of competition for the discovery and acquisition of properties considered to have a commercial potential. We compete with other companies for the acquisition of oil and gas interests, as well as for the recruitment and retention of qualified employees and other personnel.

There can be no assurance that we will be able to continue to compete effectively with other existing oil and gas companies, or any new entrants to the industry. Any failure by us to compete effectively could have a material adverse effect on our business, results of operations, financial condition and future cash flow.

We may incur a variety of costs to engage in future acquisitions, and the anticipated benefits of those acquisitions may never be realized.

As a part of our business strategy, we may make acquisitions of, or significant investments in, other assets, particularly those that would allow us to produce oil and natural gas and generate revenue to fund our exploration activities. Any future acquisitions would be accompanied by risks such as:

•: diversion of our management's attention from ongoing business concerns;
•: our potential inability to maximize our financial and strategic position through the successful development of the asset or assets acquired;
•: impairment of our relationship with our existing employees if we cannot hire employees to staff any new operations and our existing employees are required to staff both old and new operations; and

Table of Contents

•: maintenance of uniform standards, controls, procedures and policies.

We cannot guarantee that we will be able to successfully integrate any business, products, technologies or personnel that we might acquire in the future, and our failure to do so could harm our business.

We do not have reserve reports for the Concession and our expectations as to oil and gas reserves are uncertain and may vary substantially from any actual production.

We do not have reserves nor do we have any reserve reports for the Concession. A reserve report is the estimated quantities of oil and gas based on reports prepared by third party reserve engineers. Reserve reporting is a subjective process of estimating underground accumulations of oil and natural gas that cannot be measured in an exact manner. Expectations as to oil and gas reserves are uncertain and may vary substantially from any actual production.

Risks Relating to Operating in Guinea

Geopolitical instability where we operate subjects us to political, economic and other uncertainties.

We conduct business in Guinea, which is in a region of the world where there have been recent civil wars, revolutions, coup d'états and internecine conflicts. There is the risk of political violence and increased social tension in Guinea as a result of the past political upheaval, and there is a risk of civil unrest, crime and labor unrest at times. In 2010, democratic elections were held, and a president was elected and inaugurated. While these developments indicate that the political situation in Guinea is improving, external or internal political forces potentially could create a political or military climate that might cause a change in political leadership, the outbreak of hostilities, or civil unrest. Such uncertainties could result in our having to cease our Guinea operations and result in the loss or delay of our rights under the PSC.

Further, we face political and economic risks and other uncertainties with respect to our operations, which may include, among other things:

•: loss of future revenue, property and equipment, as a result of hazards such as expropriation, war, acts of terrorism, insurrection and other political risks;
•: increases in taxes and governmental royalties;
•: unilateral renegotiation or cancellation of contracts by governmental entities;
•: difficulties enforcing our rights against a governmental agency because of the doctrine of sovereign immunity and foreign sovereignty over international operations;
•: changes in laws and policies governing operations of foreign-based companies; and
•: currency restrictions and exchange rate fluctuations.

Realization of any of these factors could have a material adverse effect on our business, financial condition, results of operations and/or growth prospects. The Consortium's operations in Guinea also may be adversely affected by laws and policies of multiple jurisdictions.

We operate in Guinea, a country where corrupt behavior exists that could impair our ability to do business in the future or result in significant fines or penalties.

We operate in Guinea, a country where governmental corruption has been known to exist. There is a risk of violating either the US Foreign Corrupt Practices Act, laws or legislation promulgated pursuant to the 1997 OECD Convention on Combating Bribery of Foreign Public Officials in International Business Transactions or other applicable anti-corruption regulations that generally

Table of Contents

prohibit the making of improper payments to foreign officials for the purpose of obtaining or keeping business. In addition, the future success of our Guinea operations may be adversely affected by risks associated with international activities, including economic and labor conditions, political instability, risk of war, expropriation, terrorism, renegotiation or modification of existing contracts, tax laws and changes in exchange rates.

We are subject to governmental regulations, the cost of compliance with which may have an adverse effect on our financial condition, results of operations and future cash flow.

Oil and gas operations in Guinea will be subject to government regulation and to interruption or termination by governmental authorities on account of ecological and other considerations. It is impossible to predict future government proposals that might be enacted into law, future interpretation of existing laws or future amendments to the Guinea Petroleum Code or any other laws, or the effect those new or amended laws or changes in interpretation of existing laws might have on us. Restrictions on oil and gas activities, such as production restrictions, price controls, tax increases and pollution and environmental controls may have a material adverse effect on our financial condition, results of operations and future cash flows.

Social and economic conditions in Guinea may adversely affect our business, results of operation, financial condition and future cash flow.

As all of our potential revenue generating assets are currently located in Guinea, our operations are dependent on the economic and political conditions prevailing in Guinea. Accordingly, we are subject to the risks associated with conducting business in and with a foreign country, including the risks of changes in the country's laws and policies (including those relating to taxation, royalties, acquisitions, disposals, imports and exports, currency, environmental protection, management of natural resources, exploration and development of mines, labor and safety standards, and historical and cultural preservation). The costs associated with compliance with these laws and regulations are substantial, and possible future laws and regulations as well as changes to existing laws and regulations could impose additional costs on us, require us to incur additional capital expenditures and/or impose restrictions on or suspensions of our operations and delays in the development of our assets.

Further, these laws and regulations may allow government authorities and private parties to bring legal claims based on damages to property and injury to persons resulting from the environmental, health and safety impacts of our past and current operations and could lead to the imposition of substantial fines, penalties or other civil or criminal sanctions. If material, these compliance costs, claims or fines could have a material adverse effect on our business, results of operations, financial condition and/or growth prospects.

In addition, Guinea has high levels of unemployment, poverty and crime. These problems have, in part, hindered investments in Guinea, prompted emigration of skilled workers and affected economic growth negatively. While it is difficult to predict the effect of these problems on businesses operating in Guinea or the Guinea government's efforts to solve them, these problems, or the solutions proposed, could have a material adverse effect on our business, results of operations, financial condition and/or growth prospects.

The legal and judicial system in Guinea is relatively undeveloped and subject to frequent changes, and we may be exposed to similar risks if we operate in certain other jurisdictions.

Guinea has a less developed legal and judicial system than more established economies which could result in risks such as: (i) effective legal redress in the courts of such jurisdictions, whether in respect of a breach of contract, law or regulation, or in an ownership dispute, being more difficult to obtain; (ii) a higher degree of discretion on the part of Governmental authorities who may be

Table of Contents

susceptible to corruption; (iii) the lack of judicial or administrative guidance on interpreting applicable rules and regulations; (iv) inconsistencies or conflicts between and within various laws, regulations, decrees, orders and resolutions; or (v) relative inexperience of the judiciary and courts in such matters. In Guinea and certain other jurisdictions, the commitment of local business people, government officials and agencies and the judicial system to abide by legal requirements and negotiated agreements may be more uncertain, creating particular concerns with respect to the Concession or other licenses, permits or approvals required by us for the operation of our business, which may be susceptible to revision or cancellation, and legal redress may be uncertain or delayed. There can be no assurance that joint ventures, licenses, license applications or other legal arrangements will not be adversely affected by the actions of government authorities or others, and the effectiveness of and enforcement of such arrangements in these jurisdictions cannot be assured.

Risks Relating to Our Common Stock

The price of our common stock historically has been volatile. This volatility may affect the price at which you could sell your common stock, and the sale of substantial amounts of our common stock could adversely affect the price of our common stock.

The closing price for our common stock, adjusted for the 1-for-8 reverse stock split effected on July 1, 2013, has varied between a high of $9.44 on November 7, 2012 and a low of $3.44 on June 21, 2013 for the fiscal year ended June 30, 2013. On September 5, 2013, the closing price of our common stock was $4.65. This volatility may affect the price at which an investor could sell the common stock, and the sale of substantial amounts of our common stock could adversely affect the price of our common stock. Our stock price is likely to continue to be volatile and subject to significant price and volume fluctuations in response to market and other factors, including the other factors discussed in "—Risks Relating to Our Business and the Industry in Which We Operate"; variations in our quarterly operating results from our expectations or those of securities analysts or investors; downward revisions in securities analysts' estimates; and announcement by us or our competitors of significant acquisitions, strategic partnerships, joint ventures or capital commitments.

Our common stock is listed on the New York Stock Exchange and is subject to delisting if we do not meet continued listing standards.

Our common stock is listed in the New York Stock Exchange ("NYSE"). The NYSE has continued listing standards relating to minimum price levels, other financial criteria and compliance with corporate governance standards. In May 2012 we received a notice of non-compliance from the NYSE for failure to maintain the minimum share price requirement of $1.00 per share. In August 2013 the NYSE notified us that we have regained compliance. Failure to comply with the NYSE continued listing standards in the future would subject us to risk of delisting which could adversely affect trading in our common stock and our prospects for obtaining additional capital.

We may issue additional shares of common stock in the future, which could adversely affect the market price of our shares and cause dilution to existing stockholders.

We may issue additional shares of our common stock in the future which could adversely affect the market price of our shares. Significant sales of shares of our common stock by major stockholders, or the public perception that an offering or sale may occur also could have an adverse effect on the market price of shares of our common stock. Issuance of additional shares of common stock will dilute the percentage ownership interest of the existing stockholders, and may dilute the book value per share of our shares of common stock held by existing stockholders.

Table of Contents

Sales of substantial amounts of shares of our common stock in the public market could harm the market price of the shares of common stock.

The sale of substantial amounts of shares of our common stock (including shares issuable upon exercise of outstanding options and warrants to purchase shares) may cause substantial fluctuations in the price of shares of our common stock. Because investors may be more reluctant to purchase shares of our common stock following substantial sales or issuances, the sale of shares in an offering could impair our ability to raise capital in the near term.

Delaware law and our charter documents may impede or discourage a takeover, which could adversely impact the market price of our shares.

We are a Delaware corporation, and the anti-takeover provisions of Delaware law impose various impediments to the ability of a third party to acquire control of us, even if a change in control would be beneficial to our existing stockholders. Certain provisions of Delaware law and our certificate of incorporation and bylaws could impede a merger, takeover or other business combination involving us or discourage a potential acquirer from making a tender offer for our common stock, which, under certain circumstances, could reduce the market price of our common stock.

Item 2. Properties

Information on Oil and Gas Properties is included inItem 1. Business above in this Annual Report on Form 10-K.

Our executive and administrative offices are located at 12012 Wickchester Lane, Suite 475, Houston, Texas 77079 where we lease 18,944 square feet of space pursuant to a lease agreement with a 60 month term.

The lease agreement is for 60 months beginning on March 1, 2010, the date we took possession of the property. We are obligated to make the following base rental payments: (i) $0.00 per month during months 1 - 9; (ii) $17,472 per month during months 10 - 12; (iii) $17,957 per month during months 13 - 24; (iv) $19,413 per month during months 25 - 36; (v) $21,354 per month during months 37 - 48; and (vi) $24,266 per month during months 49 - 60.

During the fourth quarter of fiscal 2011, the lease was amended to include additional square footage.

We completed the expansion and began making lease payments during the first quarter of fiscal 2012.

During the first quarter of fiscal 2013, the lease was again amended to include additional square footage beginning in October 2012. Under the amended lease agreement, we are obligated to make the following additional rental payments: (i) $3,717.00 per month during months 1-5; (ii) $3,894.00 per month during months 6-17; and (iii) $4,071.00 per month during months 18-29.

In addition to the base rent, we are also responsible for the pro-rata share (10.664%) of excess operating expenses in connection with the property. We also paid a security deposit of $50,000 at the time of execution of the lease agreement of which $35,000 was refunded based on the lease agreement during the fourth quarter of 2012.

Item 3. Legal Proceedings

From time to time, we and our subsidiaries are involved in business disputes. We are unable to predict the outcome of such matters when they arise. Currently pending proceedings, in our opinion, will not have a material adverse effect upon our consolidated financial statements. The following is a description of certain disputes involving us.

Shareholder Lawsuits

On April 2, 2012, a lawsuit styled as a class action was filed in the U.S. District Court for the Southern District of Texas against us and our chief executive officer alleging that we made false and misleading statements that artificially inflated our stock prices. The lawsuit alleges, among other things, that we misrepresented the prospects and progress of our drilling operations, including our drilling of the Sabu-1 well and plans to drill the Baraka-1 well off the coast of the Republic of Guinea. The lawsuit seeks damages based on Sections 10(b) and 20 of the Securities Exchange Act of 1934, although the specific amount of damages is not specified. On June 1 and June 4, 2012, a number of parties made application to the Court to be appointed as lead plaintiff, and a lead plaintiff was appointed by the Court. On April 22, 2013, the lead plaintiff appointed by the Court filed a motion to withdraw as lead plaintiff. On June 12, 2013 the Court accepted the withdrawal of the lead plaintiff and appointed a new lead plaintiff to represent the class. On August 13, 2013, the newly appointed lead plaintiff also filed a motion to withdraw as lead plaintiff. The Court has not yet acted on that motion.

On April 5, 2012, a purported derivative action was filed in the District Court of Harris County, Texas, against all of our directors. The petition alleges that the directors breached their fiduciary duties in connection with positive statements about our drilling operations and the Guinea Concession and disclosures related to material weaknesses that we identified in our financial controls. The plaintiff sought unspecified damages against our directors including restitution and disgorgement of profits and advances based on asserted causes of action for breach of fiduciary duties, unjust enrichment, abuse of control, gross mismanagement, and waste of corporate assets. The derivative plaintiff sought to proceed on behalf of Hyperdynamics and did not request any damages from us in his action. On July 12, 2012, we and our directors filed special exceptions to the derivative lawsuit arguing that the plaintiff failed to plead sufficient facts to show that demand should not be made on the board prior to the filing of such a lawsuit. In response, the plaintiff amended his petition on August 13, 2012. On September 21, 2012, we and our directors renewed our special exceptions to the plaintiff's amended petition, and our motion was granted at a hearing before the court. The court allowed plaintiff another opportunity to plead his case, and plaintiff was due to file an amended petition on April 26, 2013. However, on April 25, 2013, plaintiff filed a motion to voluntarily dismiss his lawsuit without prejudice.

Iroquois Lawsuit

On May 9, 2012, a lawsuit was filed in the Supreme Court of the State of New York against us and all of our directors. The plaintiffs, five hedge funds that invested in us in early 2012, allege that we breached an agreement with the plaintiffs, and that we and the directors made certain negligent misrepresentations relating to our drilling operations. Among other claims, the plaintiffs allege that we misrepresented the status of our drilling operations and the speed with which the drilling would be completed. The plaintiffs advance claims for breach of contract and negligent misrepresentation and seek damages in the amount of $18.5 million plus pre-judgment interest. On July 12, 2012, we and the directors moved to dismiss the suit for failure to state a claim as to all defendants and for lack of personal jurisdiction over the director defendants. On June 19, 2013, the judge dismissed the negligent misrepresentation claim but declined to dismiss the breach of contract claim. The negligent misrepresentation claim was dismissed without prejudice, meaning plaintiffs could attempt to refile it. On August 12, 2013, the plaintiffs filed an amended complaint. That complaint names only us and

seeks recovery for alleged breaches of contract. We filed an answer to the plaintiffs amended complaint on September 9, 2013.

AGR Lawsuit

On June 21, 2012, our wholly-owned subsidiary, SCS, filed suit against AGR following unsuccessful negotiations to address the cost overruns associated with the Sabu-1 well drilled off the coast of the Republic of Guinea. The suit was filed in London, England in the High Court of Justice, Queen's Bench Division, Technology and Construction Court. SCS is seeking to recover damages and other relief from AGR for claims of mismanagement of the drilling of the Sabu-1 well and various breaches of contract that resulted in the cost overruns. Among other things, the lawsuit alleges that AGR mismanaged the selection, reconditioning and crew staffing for the Jasper Explorer drilling rig used to drill the Sabu-1 well, mismanaged other subcontractor relationships, failed to seek cost relief from its subcontractors, and failed to return to SCS inventory purchased by SCS but not used in the drilling of Sabu-1 well. On October 1, 2012, AGR filed a defense denying SCS's allegations and asserting a counterclaim for $22.2 million which AGR alleges to be the outstanding amount owed on the Sabu-1 drilling project, and seeking other unspecified damages and relief, including damages for loss of management time and associated expenses, a full indemnity for a claim brought by Jasper against AGR, and interest on any damages awarded. SCS filed a reply to AGR's defense on December 3, 2012 and responded by denying AGR's counterclaim. At a hearing on May 24, 2013, the Court consolidated this matter with a pending matter between Jasper Drilling Private Limited, the owner of the Jasper Explorer drilling rig, and AGR, and established a pretrial schedule contemplating one trial for both matters in June 2014.

(1): On July 1, 2013, the Company effected a 1-for-8 reverse stock split of the Company's common stock. All numbers in the table above reflect the impact of this reverse stock split.

Table of Contents

The Stock and Stock Option Plan (the "1997 Plan") of Hyperdynamics was adopted May 7, 1997 and amended on December 3, 2001, on January 21, 2005, and on February 20, 2008. The total number of shares authorized under the Plan, as amended, was 1,750,000, after giving effect to the 1-for-8 reverse stock split effected on July 1, 2013. The Board terminated the 1997 Plan effective upon stockholder approval of the 2010 Equity Incentive Plan (the "2010 Plan").

Our 2008 Restricted Stock Award Plan (the "2008 Plan") was adopted on February 20, 2008. The total number of shares authorized under the 2008 Plan was 375,000, after giving effect to the 1-for-8 reverse stock split effected on July 1, 2013. The Board terminated the 2008 Plan effective upon stockholder approval of the 2010 Plan.

On February 18, 2010, at our annual meeting of stockholders, the stockholders approved the 2010 Plan. On February 17, 2012 the 2010 Plan was amended to increase issuable shares from 625,000 to 1,250,000, in each case after giving effect to the 1-for-8 reverse stock split effected on July 1, 2013.

The 2010 Plan provides for the grants of shares of common stock, restricted stock units or incentive stock options and/or nonqualified stock options to purchase our common stock to selected employees, directors, officers, agents, consultants, attorneys, vendors and advisors. Shares of common stock, options, or restricted stock can only be granted under the Plan within 10 years from the effective date of February 18, 2010. A maximum of 1,250,000 shares, after giving effect to the 1-for-8 reverse stock split effected on July 1, 2013, are issuable under the 2010 Plan.

The purpose of the Plan is to further our interest, and the interest of our subsidiaries and our stockholders by providing incentives in the form of stock or stock options to key employees, consultants, directors, and vendors who contribute materially to our success and profitability. We believe that our future success will depend in part on our continued ability to attract and retain highly qualified personnel as employees, independent consultants, and directors. The issuance of stock and grants of options will recognize and reward outstanding individual performances and contributions and will give such persons a proprietary interest in us, thus enhancing their personal interest in our continued success and progress. We pay wages, salaries, and consulting rates that we believe are competitive. We use the 2010 Plan to augment our compensation packages.

The following table provides a reconciliation of the securities remaining available for issuance as of June 30, 2013 under the 2010 Plan:

(1): During the year ended June 30, 2012 we completed the drilling of the Sabu-1 well, our first exploratory well in our Guinea Concession, which was non-commercial. As a result, we evaluated certain geological and geophysical related costs in unproved properties along with the drilling costs of the Sabu-1 well and moved $116.3 million to proved properties. Since we have no proved reserves to include in the Full-Cost Ceiling Test, the entire $116.3 million resulted in the full amortization of our proved oil and gas properties. We amortized an additional $0.4 million of proved oil and gas properties during the year ended June 30, 2013.
(2): Adjusted to reflect the 1-for-8 Reverse Stock Split effected on July 1, 2013.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

Overview

Our corporate mission is to provide energy for the future by exploring for, developing new, and re-establishing pre-existing sources of energy. Our primary focus is the advancement of exploration work in Guinea. We also plan to continue to evaluate and consider other global oil and gas opportunities. We have no source of operating revenue, and there is no assurance when we will, if ever. We have no operating cash flows, and we will require substantial additional funds, through additional participants, securities offerings, or through other means, to fulfill our business plans.

Our operating plan within the next 12 months includes the following:

•: Initiate with Tullow and Dana a new drilling program in the deep water and commence drilling of an exploration well in the first calendar quarter of 2014.
•: Continue to evaluate and consider other global oil and gas opportunities.

Analysis of changes in financial position

Our current assets increased by $556,000 from $42,723,000 on June 30, 2012 to $43,279,000 on June 30, 2013. The increase in current assets is due to the $23.7 million in net cash proceeds received on the sale of a 40% interest in the Concession to Tullow. This was offset by cash used for general and administrative expenditures as well as capital expenditures.

Table of Contents

Our long-term assets decreased $18,984,000, from $60,073,000 on June 30, 2012, to $41,089,000 on June 30, 2013. This decrease was primarily due the reduction to our full cost pool upon the receipt of $23.7 million in net proceeds received on the sale of a 40% interest in the Concession to Tullow. This was offset by $5.4 million in capital expenditures associated with the processing of our most recent 4,000 square kilometer 3D seismic survey.

Our current liabilities decreased $4,002,000, from $26,604,000 on June 30, 2012 to $22,602,000 on June 30, 2013. The decrease in current liabilities can be attributed in part to a decrease in accrued employee bonus expense resulting from the timing of bonus payments.

Our long-term liabilities decreased from $125,000 at June 30, 2012, to $92,000 at June 30, 2013, due to the amortization of deferred rent during the year.

Results of Operations

Based on the factors discussed below, the net loss attributable to common shareholders for the year ended June 30, 2013, decreased $130,852,000, to a net loss of $18,461,000, or $0.88 per share in the 2013 period from a net loss of $149,313,000, or $7.44 per share in the 2012 period (in each case, after giving effect to the 1-for-8 Reverse Stock Split effected July 1, 2013). The net loss attributable to common shareholders for the year ended June 30, 2012, increased $138,075,000, to a net loss of $149,313,000, or $7.44 per share in the 2012 period from a net loss of $11,238,000, or $0.72 per share in the 2011 period (in each case, after giving effect to the 1-for-8 Reverse Stock Split effected July 1, 2013).

Reportable segments

We have one reportable segment: our international operations in Guinea conducted through our subsidiary SCS. SCS is engaged in oil and gas exploration activities pertaining to offshore Republic of Guinea.

Comparison for Fiscal Year 2013 and 2012

Revenues. There were no revenues for the years ended June 30, 2013 and 2012.

Depreciation. Depreciation decreased 24%, or $197,000, from the fiscal 2012 period to the fiscal 2013 period. Depreciation expense was $630,000 and $827,000 in the years ended June 30, 2013 and 2012, respectively. The decrease is primarily attributed to assets used in the prior period relating to drilling operations being fully depreciated or sold in the current period.

General, Administrative and Other Operating Expenses. Our general, administrative and other operating expenses were $17,474,000 and $22,062,000 for the years ended June 30, 2013 and 2012, respectively. This represents a decrease of 20.8%, or $4,588,000 from the fiscal 2012 period to the fiscal 2013 period. Of this decrease, $2,045,000 is attributable to a decrease in non-cash stock compensation from $5,025,000 in the 2012 to $2,980,000 in the 2013 (including $365,000 in non-cash expense associated with an award of common shares associated with a severance agreement in the current year).

The remaining $2,543,000 decrease in expense was primarily attributable to a decrease in costs associated with prospective oil and gas investment opportunities of approximately $3,747,000. Additionally, there was a decrease in travel expenses of approximately $407,000 primarily as a result of the closure of our offices in Guinea and London. This was offset by an increase in employee related costs of $577,000, which is the result of a $1,660,000 increase in severance costs associated with staff reductions offset by a $1,083,000 decrease in recurring payroll expense as a result of the staff reductions. Additionally, there were increases in legal and accounting fees of approximately $569,000, and a decrease in foreign currency transaction gains from current operations in the current period of approximately $568,000. Our foreign currency transaction gains are the result of a large balance in

Table of Contents

accounts payable denominated in foreign currency, primarily associated with our drilling contract with AGR, for which payment has been frozen pending the resolution of our legal dispute with AGR.

Amortization and Write off of Costs. We fully amortized our proved oil and gas properties of $116,312,000 and wrote off a prospective investment deposit of $10,000,000 during the year ended June 30, 2012. We amortized an additional $441,000 of proved oil and gas properties during the year ended June 30, 2013. These are additional costs recognized during the year ended June 30, 2013 associated with the non-commercial Sabu-1 well. As required by the Full-Cost Accounting rules, we evaluated and moved these costs to proved properties and then fully amortized them through our Full-Cost Ceiling Test.

Other income (expense). Other income (expense) totaled $84,000 and $(112,000) for the years ended June 30, 2013 and 2012, respectively. The increase in other income is primarily the result of the reversal to net income of other than temporary impairment of available-for-sale securities of $472,000 during fiscal 2012 while there was no such reversal in the current period. This was offset by a decrease in interest income from 2012 to 2013.

Loss from Continuing Operations. Primarily as a result of the full amortization of proved oil and gas properties and the write off of the prospective investment deposit discussed above, which together total $126,312,000 in fiscal 2012, and the decrease in selling, general and administrative expenses of $4,588,000 our loss from continuing operations decreased by $130,852,000, from $149,313,000 in the year ended June 30, 2012 to $18,461,000 for the year ended June 30, 2013.

Comparison for Fiscal Year 2012 and 2011

Revenues. There were no revenues for the years ended June 30, 2012 and 2011.

Depreciation. Depreciation increased 134%, or $474,000 due to additional depreciation associated with assets placed in service in 2012 which relate primarily to assets put in place to drill our first exploratory well. Depreciation expense was $827,000 and $353,000 in the years ended June 30, 2012 and 2011, respectively.

Selling, General and Administrative Expenses. Our selling, general and administrative expenses were $22,062,000 and $10,516,000 for the years ended June 30, 2012 and 2011, respectively. This represents an increase of 110%, or $11,546,000 from the fiscal 2011 period to the fiscal 2012 period. The increase in expense was primarily attributable to a $6,716,000 increase in employee-related costs, of which approximately $2,849,000 was non-cash stock-based compensation related to options granted to employees and others. This was driven by an increase in our full time staff from 28 employees as of July 1, 2010 to 53 employees as of June 30, 2012. The staffing increase primarily related to personnel required for our activities in Guinea and our support staff. Additionally, we incurred approximately $3,747,000 in costs with respect to several prospective oil and gas investment opportunities in the current fiscal period.

Amortization and Write off of Costs. We fully amortized our proved oil and gas properties of $116,312,000. As a result of the non-commercial Sabu-1 well drilling outcome, as required by Full-Cost Accounting rules, we evaluated and moved to proved properties $116,312,000 of costs which were then fully amortized though our Full-Cost Ceiling Test. Additionally we have written off a prospective investment deposit of $10,000,000.

Other income (expense). Other income (expense) totaled $(112,000) and $(369,000) for the years ended June 30, 2012 and 2011, respectively. The decrease is primarily the result of a loss on the warrant derivative liability in the prior fiscal period. In the fiscal 2011 period, we recognized a non-cash loss on the warrant derivative liability of $771,000. No such gain or loss was incurred on the warrant derivative liability in fiscal 2012 as the remaining warrants underlying the derivative were exercised

Table of Contents

during the second quarter of fiscal 2011. However, we recognized an other than temporary impairment of available-for-sale securities of $472,000 during fiscal 2012.

Loss from Continuing Operations. Primarily as a result of the full amortization of proved oil and gas properties and the write off of the prospective investment deposit discussed above, which together total $126,312,000, and the increase in selling, general and administrative expenses of $11,546,000 our loss from continuing operations increased by $138,075,000, from $11,238,000 in the year ended June 30, 2011 to $149,313,000 for the year ended June 30, 2012.

Liquidity and Capital Resources

Capital Resource Considerations

On December 31, 2012, our wholly owned subsidiary, SCS, closed a sale to Tullow Guinea Ltd ("Tullow"), a subsidiary of Tullow Oil plc, of a 40% gross interest in the Concession. As consideration, SCS received $27 million from Tullow as reimbursement of past costs of SCS in the Concession, and as additional consideration, Tullow agreed to: (i) pay SCS's participating interest share of future costs associated with the drilling of an exploration well in at least 2,000 meters of water in the deep water fan area of the Concession, up to a gross expenditure cap of $100 million, and (ii) pay SCS's share of costs associated with an appraisal well of the initial exploration well, if drilled, subject to a gross expenditure cap on the appraisal well of $100 million. Tullow is obligated to pay its 40% participating interest share of costs associated with the Concession as of November 20, 2012, the date of execution of the purchase and sale agreement. Tullow will begin to pay SCS's costs attributable to the Concession at the earlier of (i) the commencement of the next exploration period, September 21, 2013, or (ii) should a decision be made to begin spending on an exploration well prior to committing to the next exploration period, the date of such spending. Tullow will continue to pay SCS's costs, subject to the gross expenditure cap of $100 million, until 90 days following the date on which the rig contracted to drill the exploration well moves off the well location. As part of our agreement, Tullow will use reasonable endeavors to provide for the commencement of drilling of the exploration well not later than April 1, 2014.

The December 2012 sale to Tullow improved our cash position and liquidity, and we have adequate funds to conduct our current operations. However, our ability to drill additional wells may depend on obtaining additional resources through sales of additional interests in the Concession, equity or debt financings, or through other means. If we farm-out additional interests in the Concession, our percentage will decrease. Although we have been successful in raising capital and in entering into key participation arrangements with Dana and Tullow, we have no firm commitments for additional capital resources. The terms of any such arrangements, if made, are unknown, and may not be advantageous.

Liquidity

On June 30, 2013, we had $26.5 million in cash, $15.4 million in available-for-sale securities and $19.2 million in restricted cash, which is held in escrow in connection with our drilling contract with AGR. We had $22.7 million in liabilities, which are comprised of current liabilities of $22.6 million, which includes $20.2 million of liabilities currently pending resolution of our dispute with AGR, and noncurrent liabilities of $0.1 million. We plan to use our existing cash to fund our general corporate needs and our expenditures associated with the Concession, including our share of future capital expenditures that are not paid by Tullow on our behalf. We have no other material commitments.

We have filed suit against AGR following unsuccessful negotiations to address the cost overruns associated with the Sabu-1 well. Payment of the remaining drilling costs is pending resolution of this dispute. AGR filed a countersuit on October 1, 2012 in which AGR has made claims for additional cost of $9.5 million on a gross basis or $7.3 million based on the 77% interest we then held, which we dispute and have excluded from cost incurred to date. Additionally, AGR holds $8.8 million on a gross

basis of excess materials acquired during the drilling of the Sabu-1 well. We dispute AGR's entitlement to these assets. Resolution of this dispute may result in the recovery of a portion of the costs incurred to date; however, it is possible that the resolution of this dispute may result in additional liability associated with disputed costs.

We have satisfied all requirements of the current exploration period, which runs until September 2013 under the Concession. The Consortium sent notice to the Government of Guinea of our intention to renew the second exploration period to September 2016 and the coordinates of the area to be relinquished as required under the PSC. The second exploration period may be extended for one additional year beyond 2016 to allow the completion of a well in process and for two additional years to allow the completion of the appraisal of any discovery made. Additionally, to satisfy the September 2013-2016 work requirement, an additional exploration well is required to be drilled, which is to be commenced by the end of September 2016, to a minimum depth of 2,500 meters below seabed. We plan to commence the drilling of a deepwater exploration well during the first quarter of calendar 2014, which would satisfy the requirement to drill in the second exploration period. Tullow has agreed to pay SCS's participating interest share of future costs associated with the drilling of this well, up to a gross expenditure cap of $100 million. Additionally, Tullow has agreed to pay SCS's participating interest share of future costs associated with the drilling of an appraisal of the initial exploration well, if drilled, up to a gross expenditure cap of $100 million. We are responsible for our share of any costs exceeding the gross expenditure cap of $100 million on either well.

We have made adjustments to our overhead costs in connection with the transfer of operatorship to Tullow on April 1, 2013. Overhead adjustments during the year ended June 30, 2013 included Houston office staff reductions and the closure of our offices in London and Guinea.

We are currently involved in various legal proceedings. We are unable to predict the outcome of such matters; however, an adverse development could have an impact on liquidity.

Net cash used in operating activities for the year ended June 30, 2013 was $15,617,000 compared to $12,438,000 for the year ended June 30, 2012. The increase in cash used in operating activities is primarily attributable to changes in working capital during the period. Cash provided by investing activities for the year ended June 30, 2013 was $4,565,000 compared to cash used in investing activities of $59,135,000 in the year ended June 30, 2012. This decrease in cash used was primarily attributable to a decrease in capital expenditures from 2012, during which we drilled a well, to 2013. Additionally, in the current period we received $23.7 million in net proceeds from the sale of an interest in our oil and gas properties. This was offset by the purchase of $15.5 million in available-for-sale securities in the current year compared to the prior period in which proceeds from the sale of available-for-sale securities were approximately $53.8 million. There was net cash provided by financing activities for the year ended June 30, 2013 of $372,000 compared to $28,832,000 during the year ended June 30, 2012. We received approximately $28,162,000 in proceeds from the issuance of stock during fiscal 2012, whereas no cash was received for the issuance of stock in the current year.

Contractual Commitments and Obligations

Our subsidiary, SCS, has $350,000 remaining of a contingent note payable due to the former owners of SCS Corporation's assets. It is payable in our common stock and it is payable only if SCS has net income in any given quarter. If SCS experiences net income in a quarter, 25% of the income will be paid against the note, until the contingency is satisfied.

CRITICAL ACCOUNTING POLICIES

Our Consolidated Financial Statements are prepared in accordance with accounting principles generally accepted in the United States, which require us to make estimates and assumptions that affect the reported amounts of assets and liabilities and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates, including those estimates that may have a significant effect on our financial condition and results of operations. Our significant accounting policies are disclosed in Note 1 to our Consolidated Financial Statements. The following discussion of critical accounting policies addresses those policies that are both important to the portrayal of our financial condition and results of operations and require significant judgment and estimates. We base our estimates and judgment on historical experience and on various other factors that are believed to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions.

Oil and Gas Properties

We account for oil and natural gas producing activities using the full-cost method of accounting as prescribed by the United States Securities and Exchange Commission (SEC). Accordingly, all costs incurred in the acquisition, exploration, and development of proved oil and natural gas properties, including the costs of abandoned properties, dry holes, geophysical costs, and annual lease rentals are capitalized. All selling, general and administrative corporate costs unrelated to drilling activities are expensed as incurred. Sales or other dispositions of oil and natural gas properties are accounted for as adjustments to capitalized costs, with no gain or loss recorded unless the ratio of cost to proved reserves would significantly change, or to the extent that the sale proceeds exceed our capitalized costs. Depletion of evaluated oil and natural gas properties is computed on the units of production method based on proved reserves. The net capitalized costs of proved oil and natural gas properties are subject to a full cost ceiling limitation in which the costs are not allowed to exceed their related estimated future net revenues discounted at 10%, net of tax considerations. In accordance with SEC release 33-8995, prices based on the preceding 12-months' average price based on closing prices on the first day of each month, or prices defined by existing contractual arrangements, are used in deriving future net revenues discounted at 10%, net of tax. The application of the full-cost method of accounting for oil and gas properties generally results in higher capitalized costs and higher depreciation, depletion and amortization rates compared to the successful efforts method of accounting for oil and gas properties.

Costs Excluded

Costs associated with unevaluated properties are excluded from the full-cost pool until we have made a determination as to the existence of proved reserves. We review our unevaluated properties at the end of each quarter to determine whether the costs incurred should be transferred to the full-cost pool and thereby subject to amortization.

Table of Contents

We assess all items classified as unevaluated property on a quarterly basis for possible impairment or reduction in value. We assess properties on an individual basis or as a group if properties are individually insignificant. The assessment includes consideration of the following factors, among others: intent to drill; remaining lease term; geological and geophysical evaluations; drilling results and activity; the assignment of proved reserves; and the economic viability of development if proved reserves are assigned. We assess our unevaluated properties on a country-by-country basis. During any period in which these factors indicate an impairment, the cumulative drilling costs incurred to date for such property and all or a portion of the associated leasehold costs are transferred to the full-cost pool and are then subject to amortization. However, if proved reserves have not yet been established in a full-cost pool, these costs are charged against earnings. For international operations where a reserve base has not yet been established, an impairment requiring a charge to earnings may be indicated through evaluation of drilling results, relinquishing drilling rights or other information. At June, 30, 2013, we had $20.2 million of capitalized costs associated with our Guinea operations, which is net of $116.8 million in amortization as a result of reclassifying costs incurred on previously unevaluated properties to proved properties.

Environmental Obligations and Other Contingencies

Management makes judgments and estimates in accordance with applicable accounting rules when it establishes reserves for environmental remediation, litigation and other contingent matters. Provisions for such matters are charged to expense when it is probable that a liability has been incurred and reasonable estimates of the liability can be made. Estimates of environmental liabilities are based on a variety of matters, including, but not limited to, the stage of investigation, the stage of the remedial design, evaluation of existing remediation technologies, and presently enacted laws and regulations. In future periods, a number of factors could significantly change our estimate of environmental remediation costs, such as changes in laws and regulations, or changes in their interpretation or administration, revisions to the remedial design, unanticipated construction problems, identification of additional areas or volumes of contaminated soil and groundwater, and changes in costs of labor, equipment and technology. Consequently, it is not possible for management to reliably estimate the amount and timing of all future expenditures related to environmental or other contingent matters and actual costs may vary significantly from our estimates.

Fair Value of our debt and equity transactions

Many of our various debt and equity transactions require us to determine the fair value of a debt or equity instrument in order to properly record the transaction in our financial statements. Fair value is generally determined by applying widely acceptable valuation models, (e.g., the Black Scholes and binomial lattice valuation models) using the trading price of the underlying instrument or by comparison to instruments with comparable maturities and terms.

Share-Based Compensation

We follow ASC 718 which requires recognition in the financial statements of the cost of employee services received in exchange for an award of equity instruments over the period the employee is required to perform the services in exchange for the award (presumptively the vesting period). ASC 718 also requires measurement of the cost of employee services received in exchange for an award based on the grant-date fair value of the award. We account for non-employee share-based awards based upon the provisions of ASC 505-50, "Equity-Based Payments to Non-Employees."

Table of Contents

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

Our functional currency is the US dollar. We had, prior to their closures, some foreign currency exchange rate risk resulting from our in-country offices in Guinea and the United Kingdom and from certain costs in our drilling program. US dollars are accepted in Guinea and many of our purchases and purchase obligations, such as our office lease in Guinea, were denominated in US dollars. However, our costs for labor, supplies, and fuel could have increased if the Guinea Franc, the Euro, or the Pound Sterling significantly appreciated against the US dollar. We did not hedge the exposure to currency rate changes. We do not believe our exposure to market risk to be material.

REPORT OF MANAGEMENT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Management of Hyperdynamics Corporation (the "Company" or "our"), including the Company's Chief Executive Officer and Chief Financial Officer, is responsible for establishing and maintaining adequate internal control over financial reporting for the Company as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934. The Company's internal control system was designed to provide reasonable assurance to the Company's management and board of directors regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States.

Internal control over financial reporting includes the controls themselves, monitoring (including internal auditing practices), and actions taken to correct deficiencies as identified.

Internal control over financial reporting has inherent limitations and may not prevent or detect misstatements. The design of an internal control system is also based in part upon assumptions and judgments made by management about the likelihood of future events, and there can be no assurance that an internal control will be effective under all potential future conditions. Therefore, even those systems determined to be effective can provide only reasonable, not absolute, assurance with respect to the financial statement preparation and presentation. Further, because of changes in conditions, the effectiveness of internal control over financial reporting may vary over time.

Management assessed the effectiveness of the Company's internal control over financial reporting as of June 30, 2013. In making this assessment, management used the criteria for internal control over financial reporting described in Internal Control—Integrated Framework (1992) by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO"). Management's assessment included an evaluation of the design of the Company's internal control over financial reporting and testing of the operating effectiveness of its internal control over financial reporting. Management reviewed the results of its assessment with the Audit Committee of the Company's Board of Directors. Based on this assessment, management has concluded that, as of June 30, 2013, the Company's internal control over financial reporting was effective.

Deloitte & Touche LLP, the Company's independent registered public accounting firm, has issued an attestation report on the effectiveness on the Company's internal control over financial reporting as of June 30, 2013 which is included in Item 8.Consolidated Financial Statements and Supplementary Data.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM ON INTERNAL CONTROL OVER FINANCIAL REPORTING

To the Board of Directors and Shareholders of
Hyperdynamics Corporation
Houston, Texas

We have audited the internal control over financial reporting of Hyperdynamics Corporation and subsidiaries (the "Company") as of June 30, 2013, based on criteria established inInternal Control—Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Report of Management on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company's internal control over financial reporting is a process designed by, or under the supervision of, the company's principal executive and principal financial officers, or persons performing similar functions, and effected by the company's board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of June 30, 2013, based on the criteria established inInternal Control—Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements as of and for the year ended June 30, 2013 of the Company and our report dated September 11, 2013 expressed an unqualified opinion on those financial statements.

Our responsibility is to express an opinion on the financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of Hyperdynamics Corporation and subsidiaries as of June 30, 2013 and 2012, and the results of their operations and their cash flows for each of the three years in the period ended June 30, 2013, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company's internal control over financial reporting as of June 30, 2013, based on the criteria established in Internal Control—Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated September 11, 2013 expressed an unqualified opinion on the Company's internal control over financial reporting.

HYPERDYNAMICS CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

Nature of business

Hyperdynamics Corporation ("Hyperdynamics," the "Company," "we," "us," and "our") is a Delaware corporation formed in March 1996. Hyperdynamics has three wholly-owned subsidiaries, SCS Corporation Ltd (SCS), a Cayman corporation, HYD Resources Corporation (HYD), a Texas corporation, and Hyperdynamics Oil & Gas Limited, incorporated in the United Kingdom. Through SCS and its wholly-owned subsidiary, SCS Guinea SARL (SCSG), which is a Guinea limited liability company formed under the laws of the Republic of Guinea ("Guinea") located in Conakry, Guinea, Hyperdynamics focuses on oil and gas exploration offshore the coast of West Africa. Our exploration efforts are pursuant to a Hydrocarbon Production Sharing Contract, as amended (the "PSC"). We refer to the rights granted under the PSC as the "Concession." SCS began operations in oil and gas exploration, seismic data acquisition, processing, and interpretation in late fiscal 2002.

Status of our Business

On December 31, 2012, our wholly owned subsidiary, SCS, closed a sale to Tullow Guinea Ltd ("Tullow"), a subsidiary of Tullow Oil plc, of a 40% gross interest in the Concession. As consideration, SCS received $27 million from Tullow as reimbursement of past costs of SCS in the Concession, and as additional consideration, Tullow agreed to: (i) pay SCS's participating interest share of future costs associated with the drilling of an exploration well in at least 2,000 meters of water in the deep water fan area of the Concession, up to a gross expenditure cap of $100 million, and (ii) pay SCS's share of costs associated with an appraisal well of the initial exploration well, if drilled, subject to a gross expenditure cap on the appraisal well of $100 million. Tullow is obligated to pay its 40% participating interest share of costs associated with the Concession as of November 20, 2012, the date of execution of the purchase and sale agreement. Tullow will begin to pay SCS's costs attributable to the Concession at the earlier of (i) the commencement of the next exploration period, September 21, 2013, or (ii) should a decision be made to begin spending on an exploration well prior to committing to the next exploration period, the date of such spending. Tullow will continue to pay SCS's costs, subject to the gross expenditure cap of $100 million, until 90 days following the date on which the rig contracted to drill the exploration well moves off the well location. Tullow agreed to use reasonable endeavors to provide for the commencement of drilling of the exploration well not later than April 1, 2014. The $27 million payment was received by us on December 31, 2012 and was recorded as a reduction in the carrying value of our Concession, net of transaction costs of approximately $3.3 million. The transaction costs primarily consisted of our fees to Bank of America for financial advisory services in connection with the sale to Tullow.

We have conducted 2-dimensional ("2D") and 3-dimensional ("3D") surveys of portions of the Concession. The acquisition phase of the most recent 3D seismic survey covering approximately 4,000 square kilometers in the deeper water portion of the Concession was completed in 2012 by the CGG Veritas Ocean Endeavor. Processing of the most recent 3D data set is near completion. The cost for acquiring the survey, processing and other services is expected to total approximately $27.7 million gross. Remaining costs to be paid total approximately $0.5 million gross, or $0.2 million net based upon the 37% interest we hold.

We have drilled one exploratory well, the Sabu-1 well, which reached the planned total depth of 3,600 meters in February 2012. We determined the well to be non-commercial. As a result, we evaluated the costs associated with the well, moved these costs to proved properties, and fully

amortized the costs. See additional discussion in Note 3. As described in Note 11, we have filed suit against the manager of the Sabu-1 well, AGR Peak Well Management Ltd. ("AGR") following unsuccessful negotiations to address mismanagement that led to significant well cost overruns. Payment of the remaining drilling costs is pending resolution of this dispute. AGR filed a countersuit on October 1, 2012 in which AGR made claims for additional cost of $9.5 million on a gross basis or $7.3 million based on the 77% interest we then held, which we dispute and have excluded from our cost incurred to date. Resolution of this dispute may result in the recovery of a portion of the costs incurred to date; however, it is possible that the resolution of this dispute may result in additional liability associated with disputed costs.

We have no source of operating revenue and there is no assurance when we will, if ever. On June 30, 2013, we had $26.5 million in cash, $15.4 million in available-for-sale securities and $19.2 million in restricted cash, which is held in escrow in connection with our drilling contract with AGR. We had $22.7 million in liabilities, which are comprised of current liabilities of $22.6 million, which includes $20.2 million of liabilities currently pending resolution of our dispute with AGR, and noncurrent liabilities of $0.1 million. We plan to use our existing cash to fund our general corporate needs and our expenditures associated with the Concession, including our share of future capital expenditures that are not paid by Tullow on our behalf. We have no other material commitments.

We are currently involved in various legal proceedings that we believe will not have a material adverse effect upon our consolidated financial statements. However, we are unable to predict the outcome of such matters, and these proceedings may have a negative impact on our liquidity, financial condition and results of operations; See additional discussion in Note 11.

On July 1, 2013, the Company effected a reverse stock split in which each eight shares of the Company's common stock, par value $0.001 (the "Common Stock" and shares thereof, the "Common Shares"), was reclassified and combined into one share of Common Stock (the "Reverse Stock Split"). As such, we have retrospectively adjusted basic and diluted earnings per share, Common Stock, stock options and prices per share information for the Reverse Stock Split in all periods presented.

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of Hyperdynamics and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The financial statements have been prepared in accordance with accounting principles generally accepted in the United States and the rules of the Securities and Exchange Commission (SEC).

Use of Estimates

The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and expenses at the balance sheet date and for the period then ended. Actual results could differ from these estimates.

Cash and cash equivalents

Cash equivalents are highly liquid investments with an original maturity of three months or less. We maintain our cash in bank deposit accounts which, at times, exceed the federally insured limits.

Restricted cash

Included in restricted cash as of June 30, 2013 and 2012 is $19.2 million held in escrow which relates to our drilling contract with AGR. Under the terms of the drilling contract, we funded the escrow account for the sole purpose of funding our drilling project as overseen by AGR.

Joint interest receivable and allowance for doubtful accounts

We establish provisions for losses on accounts receivable if we determine that we will not collect all or part of the outstanding balance. Accounts receivable are written down to reflect management's best estimate of realizability based upon known specific analysis, historical experience, and other currently available evidence of the net collectible amount. There is no allowance for doubtful accounts as of June 30, 2013 or 2012. At June 30, 2013, all of our accounts receivable balance was related to joint interest billings to Tullow and Dana Petroleum (E&P) Limited ("Dana"), who own 40% and 23% participating interests, respectively in the Concession.

Securities classified as available-for-sale and held to maturity

Management determines the appropriate classification of debt securities at the time of purchase and reevaluates such designation as of each balance sheet date. Marketable equity securities and debt securities not classified as held-to maturity are classified as available-for-sale. Available-for-sale securities are carried at fair value, with unrealized gains and losses, net of tax, reported in other comprehensive income. Realized gains and losses, and declines in value deemed to be other-than-temporary, are included in earnings.

The cost of securities sold is based on the specific identification method. Interest and dividends on securities classified as available-for-sale are included in earnings.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES (Continued)

Costs Excluded

Full-Cost Ceiling Test

At the end of each quarterly reporting period, the unamortized cost of oil and natural gas properties is limited to the sum of the estimated future net revenues from proved properties (including future development and abandonment costs of wells to be drilled, using prices based on the preceding 12-months' average price based on closing prices on the first day of each month, or prices defined by existing contractual arrangements, are used in deriving future net revenues discounted at 10%) adjusted for related income tax effects ("Full-Cost Ceiling Test").

The calculation of the Full-Cost Ceiling Test is based on estimates of proved reserves. There are numerous uncertainties inherent in estimating quantities of proved reserves and in projecting the future rates of production, timing, and plan of development. The accuracy of any reserves estimate is a function of the quality of available data and of engineering and geological interpretation and judgment. Results of drilling, testing, and production subsequent to the date of the estimate may justify revision of such estimates. Accordingly, reserves estimates are often different from the quantities of oil and natural gas that are ultimately recovered.

During the years ended June 30, 2013 and 2012 we fully amortized $0.4 million and $116.3 million, respectively, in proved properties subject to the Full-Cost Ceiling Test. We recognized no impairment charges in the year ended June 30, 2011.

Property and Equipment, other than Oil and Gas

Property and equipment are stated on the basis of historical cost less accumulated depreciation. Depreciation is provided using the straight-line method over the estimated useful lives of the assets, generally three to five years.

Provision for Impairments of Long-lived Assets

Long-lived assets are reviewed for impairment annually or whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Impairment loss recognized is the excess of the carrying amount over the fair value of the asset. Any impairment charge

F-13

Table of Contents

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES (Continued)

is recorded through current period earnings. We recognized no impairment charges in the years ended June 30, 2013, 2012 or 2011, respectively.

Deferred Rent

Accounting principles generally accepted in the United States require rent expense to be recognized on a straight-line basis over the lease term. Rent holidays, rent concessions, rent escalation clauses and certain other lease provisions are recorded on a straight-line basis over the lease term (including one renewal option period if renewal is reasonably assured based on the imposition of an economic penalty for failure to exercise the renewal option). The difference between the rent due under the stated lease agreement compared to that of the straight-line basis is recorded as deferred rent. The short-term portion is the portion which is scheduled to reverse within twelve months of the balance sheet date and it is included in accounts payable and accrued expenses. At the beginning of our office lease, we received a free rent period, which began in March 2010 and ended in November 2010. During the free rent period from March 2010 to November 30, 2010, we recorded $140,000 of deferred rent, which is being amortized over the term of the lease.

Income Taxes

We account for income taxes in accordance with FASB Accounting Standards Codification ("ASC") 740, "Income Taxes," which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the tax and financial reporting basis of assets and liabilities and for loss and credit carryforwards. Valuation allowances are provided when recovery of deferred tax assets is not considered likely.

Tax benefits are recognized only for tax positions that are more likely than not to be sustained upon examination by tax authorities. The amount recognized is measured as the largest amount of benefit that is greater than 50 percent likely to be realized upon ultimate settlement. Unrecognized tax benefits are tax benefits claimed in our tax returns that do not meet these recognition and measurement standards. For the year ended June, 30, 2013 the Company has unrecognized tax benefits totaling $5.5 million.

Our policy is to recognize potential interest and penalties accrued related to unrecognized tax benefits within income tax expense. For the years ended June 30, 2013, 2012 and 2011, we did not recognize any interest or penalties in our consolidated statement of operations, nor did we have any interest or penalties accrued on our consolidated balance sheet at June 30, 2013 and 2012 relating to unrecognized benefits.

The tax years 2008-2012 remain open to examination for federal income tax purposes and by the other major taxing jurisdictions to which we are subject.

Stock-Based Compensation

ASC 718, "Compensation-Stock Compensation" requires recognition in the financial statements of the cost of employee services received in exchange for an award of equity instruments over the period the employee is required to perform the services in exchange for the award (presumptively the vesting period). We measure the cost of employee services received in exchange for an award based on the

F-14

Table of Contents

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES (Continued)

grant-date fair value of the award. We account for non-employee share-based awards based upon ASC 505-50, "Equity-Based Payments to Non-Employees."

Earnings Per Share (All share and per share amounts in this section have been adjusted to reflect the 1-for-8 reverse stock split effected on July 1, 2013)

Basic loss per common share has been computed by dividing net loss by the weighted average number of shares of common stock outstanding during each period. In period of earnings, diluted earnings per common share are calculated by dividing net income available to common shareholders by weighted-average common shares outstanding during the period plus weighted-average dilutive potential common shares. Diluted earnings per share calculations assume, as of the beginning of the period, exercise of stock options and warrants using the treasury stock method.

All potential dilutive securities, including potentially dilutive options, warrants and convertible securities, if any, were excluded from the computation of dilutive net loss per common share for the years ended June 30, 2013, 2012 and 2011, respectively, as their effects are antidilutive due to our net loss for those periods.

Stock options to purchase approximately 1.4 million common shares at an average exercise price of $13.12 and warrants to purchase approximately 0.4 million shares of common stock at an average exercise price of $10.40 were outstanding at June 30, 2013. Using the treasury stock method, had we had net income, approximately 0.04 million common shares attributable to our outstanding stock options would have been included in the fully diluted earnings per share calculation for the year ended June 30, 2013. There would have been no dilution attributable to our outstanding warrants to purchase common shares.

Stock options to purchase approximately 1.6 million common shares at an average exercise price of $16.72 and warrants to purchase approximately 1.7 million shares of common stock at an average exercise price of $23.52 were outstanding at June 30, 2012. Using the treasury stock method, had we had net income, approximately 0.4 million common shares attributable to our outstanding stock options and 0.2 million common shares attributable to our outstanding warrants to purchase common shares would have been included in the fully diluted earnings per share calculation for the year ended June 30, 2012.

Stock options to purchase approximately 1.2 million common shares at an average exercise price of $14.80 and warrants to purchase approximately 0.5 million shares of common stock at an average exercise price of $10.08 were outstanding at June 30, 2011. Using the treasury stock method, had we had net income, approximately 0.5 million common shares attributable to our outstanding stock options and 0.3 million common shares attributable to our outstanding warrants to purchase common shares would have been included in the fully diluted earnings per share calculation for the year ended June 30, 2011.

Contingencies

We are subject to legal proceedings, claims and liabilities. We accrue for losses associated with legal claims when such losses are probable and can be reasonably estimated. These accruals are adjusted as additional information becomes available or circumstances change. Legal fees are charged to expense as they are incurred. See Note 11 for more information on legal proceedings.

Accumulated Other Comprehensive Income (Loss), net of tax

We follow the provisions of ASC 220, "Comprehensive Income", which establishes standards for reporting comprehensive income. In addition to net income (loss), comprehensive income (loss) includes all changes to equity during a period, except those resulting from investments and distributions to the owners of the Company. At June 30, 2013, we had a balance in "Accumulated other comprehensive loss, net of income tax" on the consolidated balance sheet of $0.1 million. The components of accumulated other comprehensive loss and related tax effects were as follows (in thousands):

	Gross Value			Tax Effect		Net of Tax Value

Accumulated other comprehensive loss at June 30, 2011	$	349		$	—	$	349
Change in fair value of available-for-sale securities		123			—		123
Reclassification of other than temporary impairment of securities included in net income		(472	)		—		(472	)

Accumulated other comprehensive loss at June 30, 2012	$	—		$	—	$	—
Change in fair value of available-for-sale securities		94			—		94

Accumulated other comprehensive loss at June 30, 2013	$	94		$	—	$	94

There is no tax effect of the unrealized gain (loss) in other comprehensive income given our full valuation allowance against deferred tax assets. Total comprehensive loss was $18.6 million, $149.0 million and $11.6 million in fiscal year 2013, 2012 and 2011, respectively.

Financial instruments

The accounting standards (ASC 820, "Fair Value Measurements and Disclosures") regarding fair value of financial instruments and related fair value measurements define fair value, establish a three-level valuation hierarchy for disclosures of fair value measurement, and enhance disclosure requirements for fair value measures.

The three levels are defined as follows:

•: Level 1—inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets.
•: Level 2—inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.
•: Level 3—inputs to the valuation methodology are unobservable and significant to the fair value measurement.

Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The carrying values of cash and cash equivalents, accounts

F-16

Table of Contents

receivable—joint interest and accounts payable approximate fair value. On June 30, 2013 we held investments which were classified as available-for-sale securities and therefore were recorded at their fair value at the reporting date. Available-for-sale securities, which consist entirely of Corporate Debt securities, were valued at the closing price reported in the active market in which the security was traded.

The following table sets forth by level within the fair value hierarchy, our financial assets and liabilities (in thousands) that were accounted for at fair value on a recurring basis as of June 30, 2013:

			Fair Value Measurement at June 30, 2013

As of June 30, 2012, we had no financial assets or liabilities measured at fair value on a recurring basis.

Foreign currency gains and losses from current operations

In accordance with ASC Topic 830,Foreign Currency Matters, the functional currency of our international subsidiaries is the U.S. Dollar. Gains and losses from foreign currency transactions arising from operating assets and liabilities are included in general, administrative and other operating expense, have not been significant. Net foreign currency transaction gains (losses) were $0.1 million, $0.6 million and $0.1 million for the periods ended June 30, 2013, 2012 and 2011, respectively.

Recently issued or adopted accounting pronouncements

In June 2011, the Financial Accounting Standards Board ("FASB") issued an update to ASC 220,Comprehensive Income. This FASB Accounting Standards Update ("ASU") requires entities to present components of comprehensive income in either a continuous statement of comprehensive income or two separate but consecutive statements that would include reclassification adjustments for items that are reclassified from other comprehensive income to net income on the face of the financial statements. The amendments in this update do not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. Subsequently, in December 2011, the FASB issued ASU 2011-12 which deferred the requirements to include reclassification adjustments for items that are reclassified from other comprehensive income to net income on the face of the financial statements. The amendments in this update are effective for fiscal years, and interim periods within those years, beginning after December 15, 2011, which is fiscal 2013 for us. The amendments in this update should be applied retrospectively and early application was permitted. We adopted the applicable provisions of this update in the first quarter of fiscal 2013. The adoption of this update resulted in the addition of the Consolidated Statements of Comprehensive Income (Loss) in our consolidated financial statements.

In February 2013, the FASB issued ASU 2013-02,Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, which requires that companies present, either in a single note or parenthetically on the face of the financial statements, the effect of

F-17

Table of Contents

HYPERDYNAMICS CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES (Continued)

significant amounts reclassified from each component of accumulated other comprehensive income based on its source and the income statement line items affected by the reclassification. This accounting guidance will be effective for our first quarter in fiscal 2014. We do not expect ASU 2013-02 to have a material impact on our disclosures.

In July 2013, the FASB issued ASU 2013-11,Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward exists, which requires that an entity present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. ASU 2013-11 eliminates diversity in practice for presentation of an unrecognized tax benefits when such a carryforward is available to reduce the taxable income or tax payable that would result from the disallowance of a tax position. This accounting guidance will be effective for our first quarter in fiscal 2015. We do not expect ASU 2013-11 to have a material impact on our disclosures.

Subsequent Events

The Company evaluated all subsequent events from June 30, 2013 through the date of issuance of these financial statements.

2. PROPERTY AND EQUIPMENT

A summary of property and equipment as of June 30, 2013 and 2012 is as follows:

		$	710		$	1,584

We review assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. As of June 30, 2013 and 2012, there were no impairments of property and equipment.

3. INVESTMENT IN OIL AND GAS PROPERTIES

Investment in oil and gas properties consists entirely of our Guinea Concession in offshore West Africa. We owned a 77% participating interest in our Guinea Concession prior to the sale of a 40% gross interest to Tullow which closed on December 31, 2012. We now own a 37% interest in the Concession.

Guinea Concession

We have been conducting exploration work related to the area off the coast of Guinea since 2002. On September 22, 2006, we, acting through SCS, entered into the PSC with Guinea. Under that agreement, we were granted certain exclusive contractual rights by Guinea to explore and exploit offshore oil and gas reserves, if any, off the coast of Guinea. We are conducting our current work in Guinea under the PSC, as amended on March 25, 2010.

The PSC Amendment clarified that we retained a Contract Area of approximately 25,000 square kilometers, which is approximately equivalent to 9,650 square miles or 30% of the original Contract Area under the PSC, following a December 31, 2009 relinquishment of approximately 70% of the original Contract Area. The PSC Amendment requires that the Consortium relinquish an additional 25% of the retained Contract Area by September 30, 2013. Under the terms of the PSC Amendment, the first exploration period ended and the Consortium entered into the second exploration period on September 21, 2010. The second exploration period runs until September 2013, may be renewed to September 2016 and may be extended for one (1) additional year to allow the completion of a well in process and for two (2) additional years to allow the completion of the appraisal of any discovery made. The Consortium sent a notice to the Government of Guinea of our intention to renew the second exploration period to September 2016 and the coordinates of the area to be relinquished.

The PSC Amendment required the drilling of an exploration well, which had to be commenced by the year-end 2011, to a minimum depth of 2,500 meters below seabed. This requirement was satisfied with the drilling of the Sabu-1 well which was commenced during October of 2011 and reached the minimum depth of 2,500 meters below the seabed in February of 2012. The Consortium is required to drill an additional exploration well, which is to be commenced by the end of September 2016, to a minimum depth of 2,500 meters below seabed. The PSC Amendment requires the expenditure of $15 million on each of the exploration wells ($30 million in the aggregate). The Consortium is also required to acquire a minimum of 2,000 square kilometers of 3D seismic by September 2013 with a minimum expenditure of $12 million. This requirement was satisfied with the first 3D seismic survey acquired in 2010. Fulfillment of work obligations exempts us from expenditure obligations and exploration work in excess of minimum work obligations for each exploration period may be carried forward to the following exploration period.

Under the PSC Amendment, Guinea may participate in development of any discovery at a participating interest of up to 15% of costs being carried for its share. The cost of that carry is to be recovered out of 62.5% of Guinea's share of cost and profit oil. The PSC Amendment removed the right of first refusal held by us covering the relinquished acreage under the original PSC. The PSC Amendment clarified that only those eligible expenditures, which were made following the date the PSC was signed, on September 22, 2006, are eligible for cost recovery. We are required to establish an annual training budget of $200,000 for the benefit of Guinea's oil industry personnel, and we are also obligated to pay an annual surface tax of $2.00 per square kilometer on our retained Concession acreage. The PSC Amendment also provides that should the Guinea government note material differences between provisions of the PSC Amendment and international standards or the Petroleum Code, the parties will renegotiate the relevant articles.

In July 2013, a proposal was submitted for a Second Amendment to the PSC (the "Second PSC Amendment") to the Government of Guinea formally adding Tullow as a Contractor to the PSC as well as addressing other administrative issues.

Under the PSC and PSC Amendment our Guinea Concession is subject to a 10% royalty interest to Guinea. Of the remaining 90% of the first production, we will receive 75% of the revenue for recovery of the cost of operations, and Guinea will receive 25%.

After recovery cost of operations, revenue will be split as outlined in the table below:

Daily production (b/d)

From 0 to 2,000	25	%	75	%
From 2,001 to 5,000	30	%	70	%
From 5,001 to 100,000	41	%	59	%
Over 100,001	60	%	40	%

The Guinea Government may elect to take a 15% working interest in any exploitation area.

In May 2010, the government of Guinea issued a Presidential Decree approving the PSC, as amended for the sale of the 23% participating interest to Dana, and again in December 2012 for the sale of a 40% gross interest to Tullow.

Sale of Interest to Tullow

In connection with the transaction, SCS, Tullow and Dana entered into a Joint Operating Agreement Novation and Amendment Agreement reflecting that as a result of the sale to Tullow, the interest of the parties in the Concession are SCS 37%, Dana 23%, and Tullow 40%, and that Tullow will be bound by the PSC and the Joint Operating Agreement previously entered into between SCS and Dana. Tullow will assume all the respective liabilities and obligations of SCS in respect of the assigned 40% interest. SCS and Tullow executed a Deed of Assignment. The Assignment was approved by Guinea's Ministry of Mines and Geology by issuing an Arrêté on December 27, 2012 which formally

authorized our assignment of a participating interest to Tullow. SCS, Dana and Tullow have elected Tullow as the Operator of the Concession beginning April 1, 2013.

AGR Peak Well Management Limited

Effective November 30, 2010, we contracted with AGR to manage our exploration drilling project offshore Republic of Guinea to handle well construction project management services, logistics, tendering and contracting for materials as well as overall management responsibilities for the drilling program. On June 21, 2012, our wholly-owned subsidiary, SCS, filed suit against AGR following unsuccessful negotiations to address the cost overruns associated with the Sabu-1 well drilled off the coast of the Republic of Guinea. See additional discussion within Note 11.

CGG Veritas

On September 20, 2011, we entered into an Agreement for the Supply of Marine Seismic Data ("3D Seismic Contract") with CGG Veritas ("Veritas"). The area of the 3D acquisition is just southwest and adjacent to one of the 3D surveys obtained by us in 2010. Under the terms of the 3D Seismic Contract, Veritas agreed to conduct the acquisition phase of a 4,000 square kilometer 3D seismic survey of the area that is subject to our rights, or Concession, to explore offshore Republic of Guinea. Our goal in contracting for the 3D seismic survey is to investigate multiple possible deepwater submarine fans seen on 2D seismic data that was previously obtained by us. The survey commenced in November 2011, using the survey vessel Oceanic Endeavour. The cost for acquiring the survey, processing and other services is expected to total approximately $27.7 million gross. As of June 30, 2013 the Consortium has incurred $27.5 million on a gross basis.

Accounting for oil and gas property and equipment costs

We follow the "full-cost" method of accounting for oil and natural gas property and equipment costs. Under this method, internal costs incurred that are directly identified with exploration, development, and acquisition activities undertaken by us for our own account, and which are not related to production, general corporate overhead, or similar activities, are capitalized. For the years ended June 30, 2013 and 2012, we capitalized $2.7 million and $6.6 million of such costs respectively. Capitalization of internal costs was discontinued April 1, 2013 when Tullow became the operator. Geological and geophysical costs incurred that are directly associated with specific unproved properties are capitalized in "Unevaluated properties excluded from amortization" and evaluated as part of the total capitalized costs associated with a prospect. The cost of unproved properties not being amortized is assessed to determine whether such properties have been impaired. In determining whether such costs should be impaired, we evaluate current drilling results and available geological and geophysical information. Any impairment assessed to unproved properties is added to the cost of proved properties. The unamortized cost of proved oil and gas properties is limited by the Full-Cost Ceiling Test.

We exclude capitalized costs of unevaluated oil and gas properties from amortization. Geological and geophysical information pertaining to the Guinea concession was collected and evaluated and no reserves have been attributed to the Concession. In February 2012, we completed the drilling of the Sabu-1 well, which was determined to be non-commercial. As a result, we evaluated certain geological and geophysical related costs in unproved properties along with the drilling costs of the Sabu-1 well and moved $116.8 million to proved properties. As we have no proved reserves to include in the

3. INVESTMENT IN OIL AND GAS PROPERTIES (Continued)

Full-Cost Ceiling Test, the entire $116.8 million resulted in the full amortization of our proved oil and gas properties. The net costs associated with properties which remain unevaluated were $21.2 million and $39.3 million, as of June 30, 2013 and 2012, respectively. These costs are excluded from amounts subject to amortization.

The following table provides detail of total capitalized costs for our Guinea Concession as of June 30, 2013 and 2012 (in thousands):

	June 30, 2013			June 30, 2012

Oil and Gas Properties:
Proved oil and gas Properties	$	116,753		$	116,312
Unproved oil and gas Properties		14,365			32,469
Other Equipment Costs		6,809			6,809

Total Oil and Gas Properties		137,927			155,590
Less—Accumulated depreciation, depletion and amortization costs		(116,753	)		(116,312	)

Unevaluated properties not subject to amortization	$	21,174		$	39,278

Evaluation activities of these unproved properties are expected to be completed within the next one to three years. As of June 30, 2012, based on our impairment review, we fully amortized $116.3 million of our proved oil and gas properties as a result of the evaluation of our first well drilled. An additional $0.4 million in Sabu-1 well related costs were recognized during the first quarter of fiscal 2013. These costs were capitalized in proved oil and gas properties and fully amortized.

During the year ended June 30, 2013, we incurred $5.4 million of geological and geophysical costs, primarily related to our 3D seismic acquisition and processing work which commenced in November 2011. During the year ended June 30, 2012, we incurred $28.6 million of geological and geophysical costs, primarily related to our 3D seismic acquisition and processing work which commenced in November 2011, and we incurred $90.8 million of other exploration costs for our Guinea Concession during the year ended June 30, 2012, primarily related to the drilling of our first well which commenced in October 2011.

Write-off of Prospective Investment Deposit

We made payments of $5.0 million each in connection with a prospective oil and gas investment on September 20, 2011 and November 15, 2011. The $10.0 million in deposits were to have been credited on the purchase price of the prospective investment. As negotiations terminated without an agreement, we wrote off this deposit. The $10.0 million write off has been included as an operating expense in our Statement of Operations for the year ended June 30, 2012.

4. INVESTMENTS

During the third and fourth quarters of fiscal 2013, we purchased a total of $15.5 million in debt securities which were classified as available-for-sale.

7. WARRANT DERIVATIVE LIABILITY

Effective July 1, 2009, we adopted FASB ASC Topic No. 815-40 (formerly EITF 07-05) which defines determining whether an instrument (or embedded feature) is indexed to an entity's own stock. This guidance specifies that a contract that would otherwise meet the definition of a derivative but is both (a) indexed to our own stock and (b) classified in stockholders' equity in the statement of financial position, would not be considered a derivative financial instrument and provides a two-step model to be applied in determining whether a financial instrument or an embedded feature is indexed to an issuer's own stock and thus able to qualify for the scope exception.

HYPERDYNAMICS CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

7. WARRANT DERIVATIVE LIABILITY (Continued)

As a result of this adoption, certain warrants previously treated as equity pursuant to the derivative treatment exemption are no longer afforded equity treatment because these warrants have an adjustment provision applicable to the exercise price that adjusted the exercise price downward in the event we subsequently issued common stock, stock warrants, stock options or convertible debt with a stock price, exercise price or conversion price lower than YA Global Investments, LP ("YA Global") exercise price, originally $16.00 per share (after giving effect to the 1-for-8 Reverse Stock Split effected July 1, 2013). As a result, the warrants are not considered indexed to our stock, and as such, all future changes in the fair value of these warrants were recognized currently in earnings in our consolidated statement of operations under the caption "Other income (expense)—Gain (loss) on warrant derivative liability" until such time as the warrants were exercised.

The exercise price of certain warrants issued to YA Global, which were completely exercised prior to December 31, 2010, were subject to adjustment in the event we subsequently issue common stock, stock warrants, stock options or convertible debt with a stock price, exercise price or conversion price lower than YA Global's exercise price, originally $16.00 per share (after giving effect to the 1-for-8 Reverse Stock Split effected July 1, 2013). If these provisions had triggered, YA Global would have received warrants to purchase additional shares of common stock and a reduction in the exercise price of all their warrants.

As such, effective July 1, 2009, we reclassified from additional paid-in capital, as a cumulative effect adjustment, $1,585,000 to Warrant Derivative Liability to recognize the fair value of the YA Global Warrants as if these warrants had been treated as a derivative liability since their issuance in February 2008.

In September 2010, YA Global exercised 58,576 of these warrants on a cashless basis (after giving effect to the 1-for-8 Reverse Stock Split effected July 1, 2013). This reduced the derivative liability by $705,000 and increased additional paid-in capital by the same amount. During the six months ended December 31, 2010, we recognized a $771,000 non-cash loss related to the remaining YA Global warrants.

In October 2010, YA Global exercised its remaining warrants into 20,201 shares of stock on a cashless basis (after giving effect to the 1-for-8 Reverse Stock Split effected July 1, 2013). As a result, we reduced the remaining derivative liability by $649,000 and increased additional paid-in capital by the same amount. No warrant derivative liability exists as of June 30, 2013 or 2012.

Federal Income taxes are not currently due since Hyperdynamics has had losses since inception. Components of deferred tax assets as of June 30, 2013 and 2012 are as follows (in thousands):

Net non-current deferred tax assets (liabilities)	$	—		$	—

Deferred tax assets have been fully reserved due to determination that it is more likely than not that the Company will not be able to realize the benefit from them.

Hyperdynamics has U.S. net operating loss carryforwards of approximately $92.9 million at June 30, 2013. The U.S. net operating losses contains excess tax benefits related to stock compensation in the amount of $2.2 million which have not been included in the financial statements.

Internal Revenue Code Section 382 restricts the ability to use these carryforwards whenever an ownership change, as defined, occurs. Hyperdynamics incurred such an ownership change on January 14, 1998 and again on June 30, 2001. As a result of the first ownership change, Hyperdynamics' use of net operating losses as of January 14, 1998, of $949,000, is restricted to $151,000 per year. The availability of losses from that date through June 30, 2001 of $3,313,000 is restricted to $784,000 per year.

The Company underwent a restructuring during fiscal 2012 that removed approximately $13.2 million of net operating losses from the U.S. consolidated tax return. It is unlikely that the entity where these net operating losses reside will ever generate U.S. taxable income sufficient to utilize any of these losses. Due to the existence of the valuation allowance, it is not expected that any possible limitation will have an impact on the results of operations or financial position of the Company. The U.S. net operating loss carryforwards expire from 2019 to 2033.

8. INCOME TAXES (Continued)

Our policy is to include potential accrued interest and penalties related to unrecognized tax benefits within our income tax provision account. We have no accruals for the payment of interest, net of tax benefits, or penalties as of June 30, 2013, 2012, and 2011, respectively.

We file income tax returns, including tax returns for our subsidiaries, with federal, state, local, and foreign jurisdictions. Our tax returns are subject to routine compliance review by the taxing authorities in the jurisdictions in which we file tax returns in the ordinary course of business. We consider the United States to be our most significant tax jurisdiction; however, the taxing authorities in Guinea may audit various tax returns. We currently have no ongoing federal or state audits. The normal statute of limitations for tax returns being available for IRS audit is three years from the filing date of the return. However, net operating losses are subject to adjustment upon utilization of the loss to offset taxable income regardless of when the net operating loss was generated. Therefore, all of our historic losses are subject to adjustment until they are utilized or expire. We do not believe there will be any decreases to our unrecognized tax benefits within the next twelve months.

9. SHAREHOLDERS' EQUITY

Series A Preferred Stock

In January 2000, we issued 3,000 shares of Series A Convertible Preferred Stock for net proceeds of $2,604,190. The stated value was $1,000 per share and par value is $0.001. This series was non-voting and had a dividend rate of 4%, payable at conversion in either cash or shares of common stock, at Hyperdynamics' option. During 2000 and 2001, 1,055 shares were converted to common stock. As a result, 1,945 shares remained outstanding at June 30, 2010. By terms of the original agreement, the preferred shares were convertible into Hyperdynamics' common stock at a price equivalent to the lower of the trading price when purchased of $5.25 or 80% of the current 5-day trading average. All or any of the stock could be converted at any time at the holder's option. According to the terms of the agreement, all preferred shares outstanding as of January 30, 2002 were to be automatically converted to common stock. If the Series A stock had been converted at that time, approximately 607,750 shares of common stock would have been issued (after giving effect to the 1-for-8 Reverse Stock Split effected July 1, 2013). This conversion did not occur because of legal claims filed by both the Series A shareholders and Hyperdynamics against each other.

Since the outcome was not known and no conversion had been effected, Hyperdynamics continued to accrue dividends on the 1,945 shares through September 30, 2004. Management evaluated the accrual as of September 30, 2004 and determined the accrual should be discontinued. Management reevaluated the accrual periodically and considered the accrual to be adequate to cover the liability, if any, pursuant to the lawsuit.

On December 30, 2010, we entered into a settlement agreement pursuant to which we issued 29,930 shares of our common stock (after giving effect to the 1-for-8 Reverse Stock Split effected July 1, 2013) in connection with the conversion of 1,945 outstanding shares of Series A Preferred Stock. As part of the settlement, we were relieved of any Series A Preferred Stock dividend payments, two former officers agreed to the cancellation of an aggregate of 100,000 warrants which had an exercise price of $32.00 and 938 shares of our common stock were surrendered to us (in each case, after giving effect to the 1-for-8 Reverse Stock Split effected July 1, 2013). As a result of this agreement, we were not required to issue the full amount of convertible securities under the terms of the Series A

In addition, we granted to the Underwriter a 45-day option to purchase up to 468,750 additional shares of common stock from us at the offering price, less underwriting discounts and commissions. On March 25, 2011, the Underwriter exercised its option with respect to all 468,750 shares.

Closing of the sale of the shares of common stock, including the 468,750 shares purchased pursuant to exercise of the option by the Underwriter, was held on March 30, 2011. The Company received net proceeds, after underwriting discounts and commissions, and other transaction expenses, of approximately $136.1 million.

For exercise of options:

meeting, we had two stock award plans: the Stock and Stock Option Plan, which was adopted in 1997 ("1997 Plan") and the 2008 Restricted Stock Award Plan ("2008 Plan"). In conjunction with the approval of the 2010 Plan at the annual meeting, the 1997 Plan and 2008 Plan were terminated as of February 18, 2010. Subsequently, on February 17, 2012, the 2010 Plan was amended to increase the maximum shares issuable under the 2010 Plan.

The 2010 Plan provides for the grants of shares of common stock, restricted stock or incentive stock options and/or nonqualified stock options to purchase our common stock to selected employees, directors, officers, agents, consultants, attorneys, vendors and advisors of ours' or of any parent or subsidiary thereof. Shares of common stock, options, or restricted stock can only be granted under this plan within 10 years from the effective date of February 18, 2010. A maximum of 1,250,000 shares are issuable under the 2010 Plan and at June 30, 2013, 345,906 shares remained available for issuance (in each case, after giving effect to the 1-for-8 Reverse Stock Split effected July 1, 2013).

The 2010 Plan provides a means to attract and retain the services of participants and also to provide added incentive to such persons by encouraging stock ownership in the Company. Plan grants are administered by the Compensation Committee, who has substantial discretion to determine which persons, amounts, time, price, exercise terms, and restrictions, if any.

Additionally, from time to time, we issue non-compensatory warrants, such as warrants issued to investors.

The fair value of non-market based options or warrants are estimated using the Black-Scholes valuation model. For market based options, the fair value was estimated using a Black-Scholes option pricing model with inputs adjusted for the probability of the vesting criteria being met and the median expected term for each grant as determined by utilizing a Monte Carlo simulation. Expected volatility is based solely on historical volatility of our common stock over the period commensurate with the expected term of the stock options. We rely solely on historical volatility as we do not have traded options. The expected term calculation for stock options is based on the simplified method as described in the Securities and Exchange Commission Staff Accounting Bulletin number 107. We use this method because we do not have sufficient historical information on exercise patterns to develop a model for expected term. The risk-free interest rate is based on the U. S. Treasury yield in effect at the time of grant for an instrument with a maturity that is commensurate with the expected term of the stock options. The dividend yield rate of zero is based on the fact that we have never paid cash dividends on our common stock and we do not intend to pay cash dividends on our common stock.

At June 30, 2013, there was $1.5 million of unrecognized compensation costs related to non-vested share based compensation arrangements granted to employees under the plans.

During 2013, a total of 335,447 options, with a weighted average grant date fair value of $11.17 per share, vested in accordance with the underlying agreements. Unvested options at June 30, 2013 totaled 605,048 with a weighted average grant date fair value of $5.28, an amortization period of two to three years and a weighted average remaining life of 3.33 years.

Liability Awards (All share and per share amounts in this section have been adjusted to reflect the 1-for-8 reverse stock split effected on July 1, 2013)

During the first quarter of 2012, our Board of Directors approved an increase in authorized shares under the 2010 Plan from 625,000 to 1,250,000 subject to shareholder approval. Prior to receiving shareholder approval, we reached the limit of shares available under the 2010 Plan during the first quarter of fiscal 2012, at which point we concluded that all additional awards granted should be classified as liabilities until shareholders approved the increase in the maximum shares issuable under the 2010 plan. Pending shareholder approval of the amended 2010 Plan, we granted options to purchase 147,565 shares of our common stock to employees. The 2010 Plan was amended by a shareholder vote to increase issuable shares from 625,000 to 1,250,000 on February 17, 2012. The fair value on the date of modification was reclassified from a liability classification to equity. As of the modification date, we have recalculated the fair value of the awards and will amortize the unrecognized expense over the remaining vesting period.

Year ended June 30, 2013:

On November 21, 2012, warrants to purchase a total of 6,375 shares of our common stock were granted at an exercise price of $7.84. The warrants were immediately exercisable and have a term of 24 months from the date they were granted. The exercise price of the warrants may be adjusted in the case of stock splits, stock dividends or combinations of shares, or in the event the Company issues rights, options or warrants to all holders of the Company's common stock with an exercise or purchase price less than the volume weighted average price of the Company's shares on the record date. The warrants are considered indexed to our common stock and therefore are not considered a derivative. The warrants issued to the investors had a fair value of $16,000.

LITIGATION AND OTHER LEGAL MATTERS

From time to time, we and our subsidiaries are involved in business disputes. We are unable to predict the outcome of such matters when they arise. Other than disputes currently disclosed under litigation, we are unaware of any other disputes that exist and do not believe that the ultimate resolution of such matters would have a material adverse effect on our financial statements. We review the status of on-going proceedings and other contingent matters with legal counsel. Liabilities for such items are recorded if and when it is probable that a liability has been incurred and when the amount of the liability can be reasonably estimated. If we are able to reasonably estimate a range of possible losses, an estimated range of possible loss is disclosed for such matters in excess of the accrued liability, if any. Liabilities are periodically reviewed for adjustments based on additional information.

On April 22, 2013, the lead plaintiff appointed by the Court filed a motion to withdraw as lead plaintiff. On June 12, 2013 the Court accepted the withdrawal of the lead plaintiff and appointed a new lead plaintiff to represent the class. On August 13, 2013, the newly appointed lead plaintiff also filed a motion to withdraw as lead plaintiff. The Court has not yet acted on that motion. We have assessed the status of this matter and have concluded that an adverse judgment remains reasonably possible, but not probable. As a result, no provision has been made in the consolidated financial statements. Given the early stage of this dispute, we are unable to estimate a range of possible loss; however, in our opinion, the outcome of this dispute will not have a material effect on our financial condition and results of operations.

AGR Lawsuit

As of June 30, 2013 $19.2 million remains in an escrow account established to fund the well drilling project. As described above, our claim against AGR seeks recovery of monies paid out as a result of AGR's mismanagement of the project. In addition to the amounts paid, to comply with relevant accounting rules, we have accrued an additional $21.5 million of costs on a gross basis for costs AGR claims are associated with the drilling of the Sabu-1 well. We have not paid these funds to AGR and dispute AGR's entitlement to these funds. Additionally, AGR holds $8.8 million on a gross basis of excess materials acquired during the drilling of the Sabu-1 well. We dispute AGR's entitlement to these assets. Finally, an additional amount of $9.5 million on a gross basis or $7.3 million based on the 77% interest we then held is sought by AGR. Because of our claim, and because we dispute the validity of these charges, we have not accrued for this amount. We have assessed the status of AGR's claims and have concluded that although an adverse judgment is reasonably possible, it is not probable. As a result, no provision for the $9.5 million has been made in the consolidated financial statements. In our opinion, the outcome of this dispute will not have a material effect on our financial condition and results of operations.

shares outstanding during that period. In addition, certain potentially dilutive securities were not included in any of the quarterly computations of diluted net loss per share because to do so would have been antidilutive.

13. SUPPLEMENTAL OIL AND GAS INFORMATION (UNAUDITED)

In December 2008 the SEC announced revisions to its regulations on oil and gas reporting. In January 2010, the Financial Accounting Standards Board issued an accounting standards update which was intended to harmonize the accounting literature with the SEC's new regulations.

Future cash flows beginning in for 2010 would be computed by applying average price for the year to the year-end quantities of proved reserves. The average price for the year would be calculated using the twelve month period prior to the ending date of the period covered by the report, determined as an unweighted arithmetic average of the first day of the month price for each month within such period. The Company had no proved reserves in 2013, 2012, and 2011.

Estimates of reserve quantities and related standardized measure of discounted net cash flows are estimates only, and are not intended to reflect realizable values or fair market values of reserves. Reserve estimates are inherently imprecise and estimates of new discoveries are more imprecise than producing oil and gas properties. Additionally, the price of oil has been very volatile and downward changes in prices can significantly affect quantities that are economically recoverable. Accordingly, estimates are expected to change as future information becomes available and these changes may be significant.

Proved reserves are estimated reserves of crude oil and natural gas that geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions. Proved developed reserves are those expected to be recovered through existing wells, equipment and operating methods.

The standardized measure of discounted future net cash flows are computed by applying average price for the year (with consideration of price changes only to the extent provided by contractual arrangements) to the estimated future production of proved oil and gas reserves, less estimated future expenditures (based on year-end costs) to be incurred in developing and producing the proved reserves, less estimated future income tax expenses. The estimated future net cash flows are then discounted using a rate of 10% per year to reflect the estimated timing of the future cash flows.

Item 9A. Controls and Procedures

We conducted an evaluation under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures. The term "disclosure controls and procedures," as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by the company in the reports it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Commission's rules and forms. Disclosure controls and procedures also include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company's management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective.

In fiscal year 2012, we identified certain control deficiencies resulting from the lack of effective detective and monitoring controls being designed within internal control over financial reporting. Such deficiencies related to oversight and review of financial information in the area of income taxes.

Subsequently, during the fiscal year ended June 30, 2013, changes were made to our internal control over financial reporting for income taxes. Such changes to internal control included additional review and oversight controls over the reporting for income taxes. As a result of these changes in internal control, we have concluded that the fiscal year 2012 deficiencies related to the oversight and review of financial information in the area of income taxes have been remediated as of June 30, 2013.
