Overview

Nearly 70% of the earth ’s surface is covered by water, with over 40% of the world’s population living within approximately 150 miles of a coast. Thousands of information gathering and/or power systems are deployed in the oceans today to increase understanding of weather, climate change, biological processes, and marine mammal patterns and to support exploration and operations for industries such as oil and gas. Most of these systems are powered by battery, solar, wind, fuel cell, or fossil fuel generators that may be unreliable and expensive to operate while they also may be limited in their ability to deliver ample electric power. These current systems often necessitate significant tradeoffs in sensor accuracy, data processing and communications bandwidth and frequency in order to operate given limited available power. More persistent power systems requiring less maintenance, such as our systems, may have the ability to save costs over these current systems. Just as importantly, increases in available power may allow for better sensors, faster data sampling and higher frequency communication intervals up to real-time which could as a result improve scientific and economic returns.

Founded in 19 84 and headquartered in Pennington, New Jersey, we believe we are the leader in ocean wave power conversion technology. Our PB3 PowerBuoy is our first fully commercial product which generates electricity by harnessing the renewable energy of ocean waves. In addition to our PB3 PowerBuoy, we continue to develop our PowerBuoy product line based on modular, ocean-going buoys, which we have been periodically ocean testing since 1997.

The PB3 PowerBuoy generates power for use in remote offshore locations, independent of a conventional power grid, and it incorporates a unique onboard power take-off (“PTO”) system, which incorporates both energy storage and energy management and control systems. The PB3 generates up to 3 kilowatts (“kW”) of peak power during recharging of the onboard batteries. Power generation is deployment-site dependent whereby average power generated can increase substantially at very active sites. Our standard energy storage system (“ESS”) has an energy capacity of up to a nominal 150 kilowatt hours (“kWh”) to meet specific application requirements. We continue to develop and test our new PowerBuoys, with the objective to incrementally scale up in power production. We believe there is a substantial addressable market for the current capabilities of our PB3, which we believe could be utilized in a variety of applications.

In addition to leveraging earlier design aspects of our autonomous PowerBuoy, the PB3 has undergone extensive factory and in-ocean design validation testing. Currently, our engineering efforts are focused primarily on cost reduction and life extensions of the PB3, while also scaling our technologies to increase the energy output. Our marketing efforts are focused on applications in remote offshore locations that require reliable and persistent power and communications, either by supplying electric power to payloads that are integrated directly in or on our PowerBuoy or located in its vicinity, such as on the seabed and in the water column.

Based on our market research and publicly available data, we believe that multiple markets have a direct need for our PowerBuoys including oil and gas, ocean observing, defense and security, communications. Depending on payload power requirements, sensor types and other considerations, we have found that our PowerBuoy could satisfy several application requirements within these markets. We believe that the PB3 persistently generates sufficient power to meet the requirements of many potential customer applications within our target markets.

Since fiscal 2002, government agencies have accounted for a significant portion of our revenues. These revenues were largely for the support of our development efforts relating to our technology . Today our goal is to generate the majority of our revenue from the sale or lease of our products, and sales of services to support our business operations. As we continue to develop and commercialize our products, we expect to have a net loss of cash from operating activities unless and until we achieve positive cash flow from the commercialization of our products and services. During fiscal 2017 and the first quarter of fiscal year 2018, we continued work on projects with the U.S. Department of Defense (“DOD”), and Mitsui Engineering and Shipbuilding Co., Ltd. (“MES”), while we continued to validate the reliability and power output of our PB3 PowerBuoy.

Competitive Advantages

We are commercializing our PB3 PowerBuoy by targeting customers principally in four markets that require reliable and persistent power sources in remote offshore locations (as discussed in further detail below). We believe that our wave energy products and services, and our existing commercial relationships, provide the following competitive advantages in our target markets.

●

Numerous applications within multiple, major markets . We have designed our PB3 PowerBuoy systems to address multiple offshore applications around the world. In particular, we are targeting customers with applications within the oil and gas, defense and security, ocean observing, and communications markets.

●

Considerable life-cycle cost savings over current solutions for many applications . Our PB3 PowerBuoy is designed to operate over extended intervals between required servicing, as compared to several current solutions which we have found to require more frequent recharging or replacement using offshore vessels. We believe that our PB3 PowerBuoy reduces costs over multi-year operations as compared with current solutions. These cost reductions are mostly due to reduced vessel and personnel servicing activities.

●

Real-time data communications . Some current solutions with less available power than our PowerBuoy may have limited communication capabilities or may be able to communicate data only over shorter periods due to power limitations. Some current solutions may only make data accessible upon physical retrieval of the sensor. Our PowerBuoys can be equipped with a variety of communications equipment which enables the transmission of data on a more frequent basis as compared to current solutions. We believe that more frequent data communication could enable an end-user to more quickly and proactively make data-driven decisions which could result in economic advantages.

●

Increased power and more persistence compared to certain current solutions . We have found that our PowerBuoy may provide substantially increased power and persistence than certain existing systems such as battery and solar powered. We believe that that this may allow additional sensors to be employed at the same site,a higher sensor data transmission rate to be achieved,extended operation and reduced downtime, and improved operational costs for the end-user. Each of these may contribute to accelerated operations through real-time decision making, and increased life-cycle cost savings by enabling these new capabilities.

●

Standard transportation and deployment . Our PB3 PowerBuoy does not require special handling or transportation, and instead uses conventional transportation and handling methods that are economical and readily available in standard marine operations. The PB3 can be packaged inside of a standard 40-foot shipping container which may result in lower global transportation and deployment costs than current solutions. Our PB3 PowerBuoy can be deployed using conventional vessels and conventional marine cranes and lifts.

●

Modular and scalable designs . Our PB3 PowerBuoy is designed with a modular ESS which allows us to tailor its configuration to specific application requirements, including expansion of energy storage capacity, potentially allowing for a more customized solution and potential cost savings for our customers. We believe that our PowerBuoys are scalable to higher power levels, and multiple PowerBuoys may also be installed in an array in order to achieve higher levels of aggregate power, although we have not demonstrated a PowerBuoy array.

●

Flexible electrical, mechanical and communication interfaces for sensors . The PB3 PowerBuoy can be equipped with payloads, either mounted on or within the PowerBuoy, or tethered to the PowerBuoy. The PB3 PowerBuoy has mechanical and electrical interfaces which allow for simplified integration of payloads, creating flexibility for the end user.

●

Environmentally benign and aesthetically non-intrusive system design . We believe that our PB3 PowerBuoy does not present significant risks to marine life, or emit significant levels of pollutants, and therefore has minimal environmental impact as compared to some other current solutions. We believe there is no significant audible impact and such system does not have a negative effect on marine life, as validated by the US Navy and DOE.

●

Ocean and factory tested technology . Our PB3 PowerBuoy is designed to be durable, with a design goal of a three-year interval between required maintenance activities. The PB3 has survived hurricanes and tropical storms during harsh sea conditions while deployed in the ocean. Since 1997 we have conducted ocean tests to demonstrate the viability of our technology. In 2011 we conducted multiple ocean tests of the predecessor PB3 PowerBuoy under a contract with the U.S. Navy. More recently, we conducted multiple ocean tests of our current generation PB3 PowerBuoy, including our now commercial version. In 2015, we instituted factory-based PTO accelerated life testing which simulates continuous operation under extremely harsh conditions. During the 2017 fiscal year, we also implemented additional features to accommodate the feedback received from potential customers and end-users in support of further simplifying ocean deployments and increasing product application versatility. Further, we also focused on standardizing manufacturing and production testing procedures and worked closely with our supply base in order to ensure production repeatability. To date, we have achieved over 67 million cumulative strokes across our fleet of power takeoffs with no material failures in our commercial PTO design. This is equivalent to more than four cumulative years of continuous typical ocean operation for the markets which we are pursuing.

●

Efficient design in harnessing wave energy . We have designed and validated our PB3 PowerBuoy for maximized power generation in average ocean wave conditions through optimized mechanical to electrical wave energy conversion. We have designed the onboard ESS to provide several days of continuous rated power during periods of low or no wave activity, depending on payload power consumption. The PB3 PowerBuoy is equipped with a variety of communication capabilities including satellite, cellular, and Wi-Fi that are capable of transmitting payload data in real time (e.g., sensors or equipment that require power and communications capabilities), subject to the limits of the service provider.

●

Prior commercial relationships enabled the development of our technology . Our prior and existing relationships with the U.S. Navy, DOE, U.S. Department of Homeland Security, and MES have allowed us to develop our PB3 PowerBuoy for a variety of needs in various industries. We believe these relationships have helped position us within the private sector in support of commercialization, which we believe enhances our market visibility and attractiveness to our prospective customers. For example, in 2011 our PowerBuoy provided persistent power to an integrated radar and sonar system, significantly extending the U.S. Navy’s surveillance range. We have also demonstrated persistent maritime vessel detection with the U.S. Department of Homeland Security by integrating a hydrophone onto our PowerBuoy and demonstrating enhanced maritime traffic detection. In each instance, the resulting data have informed our next design iterations to address critical operations and reliability improvements.

Business Strategy

We are commercializing our PB3 PowerBuoy for use in remote offshore power and real-time data communications applications, and in order to achieve this goal, we are pursuing the following business objectives.

●

Sell and/or Lease PowerBuoys . We believe our PB3 PowerBuoy is well suited for many remote offshore applications. We have observed potential market demand for both PowerBuoy sales and leases within our selected markets, and we intend to sell and lease PB3 PowerBuoys to these markets. Additionally, we intend to provide services associated with product sales and leases such as maintenance, remote monitoring and diagnostic, application engineering, planning, training, and logistics support required for the PB3 PowerBuoy life-cycle. We continue to increase our commercial capabilities through new hires in marketing, sales, and application support, and through engagement of expert market consultants in various geographies.

●

Concentrate sales and marketing efforts in specific geographic markets . We are currently focusing our sales and marketing efforts in North America, Europe, Australia, and parts of Asia, including Japan. We believe that each of these areas has sizeable end market opportunities, political and economic stability, and high levels of industrialization and economic development.

●

Expand our relationships in key market areas through strategic partnerships and collaborations . We believe that strategic partners are an important part of commercializing a new product. Partnerships and collaborations can be used to improve the development of overall integrated solutions, to create new market channels, to expand commercial know-how and geographic footprint, and to bolster our product delivery capabilities.

►

Commercial collaborations . We believe that an important element of our business strategy is to collaborate with other organizations to leverage our combined expertise, market presence and access, and core competences across key markets. We have formed such a relationship with several well-known groups, including MES in Japan, the National Data Buoy Center (“NDBC”), the Wildlife Conservation Society (“WCS”), Gardline Environmental (an international and multi-disciplinary marine service company), Sonalysts (with expertise in subsea and surface communications, systems integration, and big-data management), and HAI Technologies (an innovative company focusing on bringing new capabilities to the oil and gas industry). We continue to seek other opportunities to collaborate with application experts from within our selected markets.

►

Outsourcing of fabrication, deployment and service support . We outsource all fabrication, anchoring, mooring, cabling supply, and in most cases deployment of our PowerBuoy in order to minimize our capital requirements as we scale our business. Our PTO is a proprietary subsystem and is assembled and tested at our facility. We believe this distributed manufacturing and assembly approach enables us to focus on our core competencies to ensure a cost effective product by leveraging a larger more established supply base. We also continue to seek strategic partnerships with regard to servicing of our PB3 PowerBuoy.

●

PB3 cost reduction and PowerBuoy output product development . Our engineering efforts are focused on customer application development for PB3 sales, cost reduction of our PB3 PowerBuoy, and improving the energy output, reliability, maintenance interval, and expected operating life of our PowerBuoys. We continue to optimize manufacturability of our designs with a focus on cost competitiveness , and we believe that we will be able to address new and different applications by developing new products that increase energy output.

Market Opportunity

The National Oceanographic and Atmospheric Administration (“NOAA”) Ocean Enterprise Report for 2016 estimated that the annual market for what NOAA describes as the “Ocean Enterprise” is $8.5 billion. The report addressed businesses involved in the for-profit and not-for-profit businesses that support ocean measurement, observation and forecasting. Among the market sectors included in the report are oil and gas, ocean observing and security and defense sectors. We believe that this report addresses only a segment of the potential market opportunities that we are targeting in general.

S-4

Table of Contents

Oil and Gas

We believe the offshore oil and gas industry is undergoing a significant transformation. In light of industry consolidation due to relatively low oil prices, the industry continues to invest in new technologies that enable cost savings as well as the digitization of operations. The industry encompasses more than 10,000 offshore sites, including exploration, production, reservoir management, and sites pending decommissioning based on information from the U.S. Bureau of Safety and Environmental Enforcement and industry organizations and publications. We believe that opportunities to implement one or more PB3 PowerBuoys exist at a large number of these sites to provide power in applications that are not currently possible, or to displace current power solutions.

Ocean Observing

Ocean observing provides environmental intelligence to the entire ocean enterprise, which supports ocean measurement, observation and forecasting, and is an important provider of information to maritime commerce and the entire “blue economy.” Maritime commerce and the scientific community depend on information from areas such as meteorology, climate change, ocean seismometry currents, and biological processes in order to inform operations and development. These groups often require a power and communications solution in remote offshore locations. According to NOAA ’s 2016 Ocean Enterprise report, the total U.S. available ocean observing market from 2017 through 2021 for ocean based systems infrastructure is projected to be $2.0 billion.

Security and Defense

We believe that our PB3 PowerBuoy is uniquely positioned to be used to provide power and communications for multiple applications within the security and defense market. The PB3 ’s ability to power multiple payloads may be an attractive feature for defense and security, as their systems can be easily integrated into other PowerBuoy applications allowing their operation to be concealed. An example application for domestic and international defense departments and defense contractors includes forward deployed energy and communications outposts (which is a current U.S. Department of Defense program), both above and below sea surface. Other example applications include early detection and warning systems, remote sensing stations, high frequency radar, sonar, electro-optical and infrared sensors for maritime security, network communications systems, and unmanned underwater vehicle docking stations. According to a 2014 Frost and Sullivan report, market expenditures for global security reached $29.0 billion in 2012 and are projected to reach $56.5 billion in 2022. Maritime security expenditures were approximately 45% of the global security market.

Communications

We believe that opportunities also exist in other markets such as communications. The addition of near shore and offshore cellular and Wi-Fi platforms with reliable and persistent power could open new market opportunities for telecommunications carriers by displacing a portion of the maritime satellite communications market, while potentially decreasing communications costs for the marine, offshore oil and gas, and airline industries. As an example, according to a 2015 Frost & Sullivan Oil & Gas Satellite Communications market report, the estimated 2020 annual spend on satellite communications in the oil and gas market is projected to be $459 million. According to an industry research paper titled “ Prospects for Maritime Satellite Communications”, in 2015 the global maritime satellite communications market has already reached close to 338,000 terminals, with $1.7 billion in revenue at the satellite communications service provider level. The report also notes that the value of the maritime satellite communications market is expected to continue to grow over the next decade, with a 10-year compound annual growth rate of 5% in terminals and revenue, primarily due to the ever-increasing need for maritime data communications.

Implementation Strategy

We have made significant progress in redesigning and validating our commercial-ready PB3 PowerBuoy for use in remote offshore applications. Since 2015, we have brought the PB3 from initial concept to a full scale d esign. We have performed multiple prototype iterations. During this time, we have conducted a number of in-ocean tests in combination with our facility-based accelerated life testing in order to validate our commercial-ready PB3 PowerBuoy and to prepare for low rate initial production. Recently, we announced that we are relocating our corporate headquarters in the second half of calendar year 2017. We believe that this will allow us to expand our manufacturing capabilities and to move toward higher volume PowerBuoy production. Likewise, we have made progress in marketing our PB3 PowerBuoy, as evidenced by additional requests for proposals.

S-5

Table of Contents

Since 2015, we have had initial introductions or meetings with nearly 200 companies and organizations within our target markets. A large proportion of these engagements (approximately 75%) were U.S.-based, while the remaining engagements occurred in Europe, Australia, and parts of Asia including Japan. One-third of all engagements have transitioned from initial introductions to advanced, confidential discussions around specific customer applications. Many of these discussions occur at the executive, decision-making level, as well as the implementation level.

As previously noted, several of these customer application discussions have resulted in requests for proposals. Many proposal requests are for projects where our PB3 PowerBuoy is part of a larger solution demonstration, and typically include the potential lease or sale of one or more PB3 PowerBuoys, as well as required services and maintenance support. Demonstration projects are a necessary step toward broad solution deployment and revenues associated with specific applications and typically last from three months to more than one year. During the demonstration project specification, negotiation and evaluation period, we are often subject to the prospective customer’s vendor qualification process, which entails substantial due diligence of our company and capabilities, and may include negotiation of standard terms and conditions. Many proposals contain provisions which would mandate the sale or lease of PB3 PowerBuoys upon successful conclusion of the demonstration project.

We believe this is an accurate depiction of the overall sales cycle for new technology in each of our target markets, including the PB3 PowerBuoy. However, cycle times for each step of the sales cycle will vary depending on several customer factors, including, but not limited to, technical evaluation, project priorities, funding approval process, and alignment of new technology integration with the customer ’s broader operational strategy. We believe that the resulting evidence of potential demand, vis-à-vis specific application proposal requests, is indicative of significant progress in our commercialization strategy over the prior two years. The figure below depicts our accomplishments to date, including the development of a commercial product through low rate initial production and the development of new markets through customer requests for proposals for application demonstration projects. We believe that we have the potential for growth as a result of our positioning for higher volume production of our PB3 PowerBuoys and the initial indications of demand for our PB3 PowerBuoy in multiple customer applications.

In addition, we have a significant number of stock options and warrants outstanding. To the extent that outstanding stock options or warrants have been or may be exercised or other shares are issued, investors purchasing our common stock in this offering may experience further dilution. In addition, we may choose to raise additional capital due to market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans. To the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of these securities could result in further dilution to our stockholders or result in downward pressure on the price of our common stock.

Management will have broad discretion as to the use of the proceeds from this offering, and we may not use the proceeds effectively.

Our management will have broad discretion as to the application of the net proceeds from this offering, and could spend the proceeds in ways that do not necessarily improve our operating results or enhance the value of our common stock.

We may issue debt and equity securities or securities convertible into equity securities, any of which may be senior to our common stock as to distributions and in liquidation, which could negatively affect the value of our common stock.

In the future, we may attempt to increase our capital resources by entering into debt or debt-like financing that is unsecured or secured by some or all of our assets, or by issuing additional debt or equity securities, which could include issuances of secured or unsecured commercial paper, medium-term notes, senior notes, subordinated notes, guarantees, preferred stock, hybrid securities, or securities convertible into or exchangeable for equity securities, any of which may rank senior to our common stock. In the event of our liquidation, our lenders and holders of our debt and preferred securities would receive distributions of our available assets before distributions to the holders of our common stock. Because our decision to incur debt and issue securities in future offerings may be influenced by market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing or nature of our future offerings or debt financings. Further, market conditions could require us to accept less favorable terms for the issuance of our securities in the future.

As a smaller reporting company, we are subject to scaled disclosure requirements that may make it more challenging for investors to analyze our results of operations and financial prospects.

Currently, we are a “smaller reporting company,” meaning that our outstanding common stock held by non-affiliates had a market value of less than $75 million as of October 31, 201 6. As a “smaller reporting company,” we are able to provide simplified executive compensation disclosures in our filings; are exempt from the provisions of Section 404(b) of the Sarbanes-Oxley Act requiring that independent registered public accounting firms provide an attestation report on the effectiveness of internal control over financial reporting; and have certain other decreased disclosure obligations in our filings with the SEC, including being required to provide only two years of audited financial statements in annual reports. Consequently, it may be more challenging for investors to analyze our results of operations and financial prospects.

Furthermore, a material weakness in internal controls may remain undetected for a longer period because of our extended exemption from the auditor attestation requirements under Section 404(b) of the Sarbanes-Oxley Act.

Historically, our stock price has been volatile and this is likely to continue; purchasers of our common stock could incur substantial losses as a result.

Historically, the market price of our common stock has fluctuated significantly, and we expect that this will continue. Purchasers of our common stock could incur substantial losses relating to their investment in our stock as a result. For the twelve month period ending October 18, 2017, the 52-week high and low prices for our common stock were $5.89 and $1.14, respectively. Also, the stock market in general has recently experienced volatility that has often been unrelated or disproportionate to the operating performance of particular companies. These broad market fluctuations could result in fluctuations in the price of our common stock, which could cause purchasers of our common stock to incur substantial losses. The market price for our common stock may be influenced by many factors, including:

●

developments in our business or with respect to our projects;

●

the success of competitive products or technologies;

●

regulatory developments in the United States and foreign countries;

●

developments or disputes concerning patents or other proprietary rights;

●

the recruitment or departure of key personnel;

●

quarterly or annual variations in our financial results or those of companies that are perceived to be similar to us;

●

market conditions in the conventional and renewable energy industries and issuance of new or changed securities analysts’ reports or recommendations;

S-10

Table of Contents

●

the failure of securities analysts to cover our common stock or changes in financial estimates by analysts;

●

the inability to meet the financial estimates of analysts who follow our common stock;

●

investor perception of our company and of our targeted markets; and

●

general economic, political and market conditions.

We have never paid cash dividends on our common stock , and we do not anticipate paying any cash dividends in the foreseeable future.

We have not paid any cash dividends on our common stock to date. We currently intend to retain our future earnings, if any, to fund the development and growth of our business. In addition, the terms of any future debt agreements may preclude us from paying dividends. As a result, capital appreciation, if any, of our common stock will be the sole source of gain for our stockholders for the foreseeable future.

Provisions in our corporate charter documents and under Delaware law may delay or prevent attempts by our stockholders to change our management and hinder efforts to acquire a controlling interest in us.

As a result of our reincorporation in Delaware in April 2007, provisions of our certificate of incorporation and bylaws may discourage, delay or prevent a merger, acquisition or other change in control that stockholders may consider favorable, including transactions in which our stockholders might otherwise receive a premium for their shares. These provisions may also prevent or frustrate attempts by our stockholders to replace or remove our management. These provisions include:

●

advance notice requirements for stockholder proposals and nominations;

●

the inability of stockholders to act by written consent or to call special meetings; and

●

the ability of our Board of Directors to designate the terms of and issue new series of preferred stock without stockholder approval, which could be used to institute a “poison pill” that would work to dilute the stock ownership of a potential hostile acquirer, effectively preventing acquisitions that have not been approved by our Board of Directors.

The affirmative vote of the holders of at least 75% of our shares of capital stock entitled to vote is necessary to amend or repeal the above provisions of our certificate of incorporation. In addition, absent the approval of our Board of Directors, our bylaws may only be amended or repealed by the affirmative vote of the holders of at least 75% of our shares of capital stock entitled to vote.

In addition, Section 203 of the Delaware General Corporation Law prohibits a publicly held Delaware corporation from engaging in a business combination with an interested stockholder, which is generally a person who together with its affiliates owns or within the last three years has owned 15% of our voting stock, for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business combination is approved in a prescribed manner. Accordingly, Section 203 may discourage, delay or prevent a change in control of our company.

If securities or industry analysts fail to cover us, or do not publish research or publish unfavorable or inaccurate research about our business, our stock price and trading volume could decline.

The trading market for our common stock is influenced by the research and reports that industry or securities analysts may publish about us, our business or our industry from time to time. If one or more of these analysts cease coverage of usor fail to publish reports on us regularly, we could lose visibility in the financial markets, which in turn could cause the price or trading volume of our common stock to decline. Moreover, if one or more of the analysts who cover us downgrade our common stock or release a negative report, or if our operating results do not meet analyst expectations, the price of our common stock could decline.

USE OF PROCEEDS

The estimated net proceeds to be received by us from this offering are expected to be approximately $ million after deducting placement agent fees and estimated offering expenses. We intend to use the net proceeds from this offering for expanding our sales and marketing through new hires and target market experts, increasing product manufacturing capabilities, and building additional PowerBuoys to meet potential market demand, and for other general corporate purposes. This may include additional development, testing and demonstrations of our PowerBuoy system with the goal of furthering and accelerating our commercialization efforts. The amounts and timing of these expenditures will depend on a number of factors, such as the timing, scope, progress and results of our research and development efforts, the timing and progress of any partnering efforts, and the regulatory and competitive environment. As of the date of this prospectus supplement, we have not determined the amount of net proceeds to be used specifically for any particular purpose or the timing of any expenditures. Accordingly, management will retain broad discretion and flexibility in applying the net proceeds from the sale of the securities. Pending any use of the net proceeds, we intend to invest the net proceeds in repurchase contracts or deposit them in checking accounts at financial institutions.

DILUTION

If you invest in this offering, your ownership interest may be diluted to the extent of the difference between the public offering price per share and the as adjusted net tangible book value per share after giving effect to this offering. Our net tangibl e book value as of July 31, 2017, was approximately $10,085,231, or approximately $0.80 per share of common stock. Net tangible book value per share represents the amount of total tangible assets (total assets less intangible assets) less total liabilities, divided by the number of shares of our common stock outstanding as of July 31, 2017.

Dilution in net tangible book value per share represents the difference between the amount per share paid by purchasers in this offering and the net tangible book value per share of our common stock immediately after this offering. After giving effect to the sale of shares of our common stock in this offering at the public offering price of $ per share, and after deduction of fees and estimated offering expenses payable by us, our as adjusted net tangible book value as of July 31, 2017 would have been approximately $ , or approximately $ per share of common stock. This represents an immediate decrease in net tangible book value of $ per share of common stock to our existing stockholders and an immediate decrease in net tangible book value of $ per share of common stock to investors in this offering. The actual amounts above are based on 12,551,124 shares outstanding as of July 31, 2017 and do not reflect the exercise of outstanding options, because the effect of such exercise would be anti-dilutive.

We currently intend to retain all of our future earnings, if any, to finance the growth and development of our business.

DESCRIPTION OF COMMON STOCK

In this off ering, we are offering shares of our common stock.

Authorized and Outstanding Capital Stock

The following description of our common stock and provisions of our certificate of incorporation and bylaws are summaries and are qualified by reference to our certificate of incorporation and bylaws, which have been incorporated by reference as exhibits to the registration statement of which this prospectus supplement forms a part.

Our authori zed capital stock consists of 50,000,000 shares of common stock, par value $0.001 per share, and 5,000,000 shares of preferred stock, par value $0.001 per share, all of which are undesignated.

As of October 18, 2017, there were 12,524,441 shares of common stock issued and outstanding, and no shares of preferred stock were issued or outstanding. As of October 18, 2017, there also were outstanding warrants to purchase up to 145,952 shares of our common stock that became exercisable on December 8, 2016 at a price of $6.08, warrants to purchase up to 178,500 shares of our common stock which are currently exercisable at a price of $9.36, and options to purchase a total of 127,418 shares of common stock at a weighted average exercise price of approximately $15.80 per share.

Description o f Common Stock

Voting . Holders of common stock are entitled to one vote for each share held on all matters submitted to a vote of stockholders and do not have cumulative voting rights. Accordingly, holders of a majority of the shares of common stock entitled to vote in any election of directors may elect all of the directors standing for election.

Dividends . Holders of common stock are entitled to receive proportionately any dividends that may be declared by our Board, subject to any preferential dividend rights of outstanding preferred stock.

Liquidation and Distribution . Upon our liquidation, dissolution or winding up, the holders of common stock are entitled to receive proportionately our net assets available after the payment of all debts and other liabilities and subject to the prior rights of any outstanding preferred stock. Holders of common stock have no preemptive, subscription, redemption or conversion rights. Our outstanding shares of common stock are, and the shares offered by us in this offering will be, when issued and paid for, fully paid and nonassessable. The rights, preferences and privileges of holders of common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of preferred stock that we may designate and issue in the future.

Anti-Takeover Effects of Delaware Law; Our Certificate of Incorporation and Our Bylaws

Delaware law, our certificate of incorporation and our bylaws contain provisions that could have the effect of delaying, deferring or discouraging another party from acquiring control of us. These provisions, which are summarized below, are intended to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with our Board.

Removal of Directors

Our certificate of incorporation currently provides that directors may be removed only for cause and only by the affirmative vote of the holders of 75% of our shares of capital stock present in person or by proxy and entitled to vote. However, our Board a pproved an amendment to our bylaws that became effective on June 17, 2016, which permits our directors to be removed either for cause or without cause by our stockholders. At our annual meeting of stockholders for the year ended April 30, 2016 that was held on October 21, 2016 (the “ 2016 Annual Meeting ” ), we submitted a proposal to stockholders seeking stockholder approval to amend our certificate of incorporation to delete the reference to “ for cause ” in Section 6 of Article IX of the certificate of incorporation. This proposal to amend the certificate of incorporation did not receive the required affirmative vote of the holders of at least 75% of the outstanding shares of common stock entitled to vote at the meeting, so the proposal did not pass. However, we also submitted a proposal to stockholders at the 2016 Annual Meeting seeking approval to amend our certificate of incorporation to add a clause that specified that, to the fullest extent permitted by law, any provision in the Certificate of Incorporation that is contrary to a requirement of the Delaware General Corporate Law (the “DGCL”) shall be read in conformity with the applicable requirement of the DGCL. This second proposal only required the affirmative vote of the holders of a majority of the outstanding shares of common stock entitled to vote at the 2016 Annual Meeting, and it passed.

S-18

Table of Contents

The Board takes the position that under current Delaware law, the “ only for cause” provision in the certificate of incorporation regarding removal of the company’ s directors is not enforceable, and is therefore not in conformity with the applicable requirement of the DGCL. Accordingly, we will comply with the provisions of our bylaws, as amended and as described above, relating to director removal and will not seek to enforce that provision of our certificate of incorporation relating to stockholder removal of directors only for cause, as presently in effect. Under our certificate of incorporation and bylaws, any vacancy on the Board, including a vacancy resulting from an enlargement of the Board, may be filled only by vote of a majority of our directors then in office.

The limitations on the ability of our stockholders to remove directors and fill vacancies could make it more difficult for a third party to acquire, or discourage a third party from seeking to acquire, control of us.

Stockholder Action by Written Consent; Special Meetings

Our certificate of incorporation provides that any action required or permitted to be taken by our stockholders must be effected at a duly called annual or special meeting of such holders and may not be effected by any consent in writing by such holders. Our certificate of incorporation and our bylaws also provide that, except as otherwise required by law, special meetings of our stockholders can only be called by our chairman of the board, our chief executive officer, our president or the Board.

Advance Notice Requirements for Stockholder Proposals

Our bylaws establish an advance notice procedure for stockholder proposals to be brought before an annual meeting of stockholders, including proposed nominations of persons for election to the Board. Stockholders at an annual meeting may only consider proposals or nominations specified in the notice of meeting or brought before the meeting by or at the direction of the Board or by a stockholder of record on the record date for the meeting, that is entitled to vote at the meeting and that has delivered to our secretary a timely written notice in proper form of the stockholder ’ s intention to bring such business before the meeting. These provisions could have the effect of delaying until the next stockholder meeting stockholder actions that are favored by the holders of a majority of our outstanding voting securities.

Delaware Business Combination Statute

We are subject to Section 203 of the Delaware General Corporation Law. Subject to certain exceptions, Section 203 prevents a publicly held Delaware corporation from engaging in a “ business combination” with any “ interested stockholder” for three years following the date that the person became an interested stockholder, unless the interested stockholder attained such status with the approval of our Board or unless the business combination is approved in a prescribed manner. A “ business combination” includes, among other things, a merger or consolidation involving us and the “ interested stockholder” and the sale of more than 10% of our assets. In general, an “ interested stockholder” is any entity or person beneficially owning 15% or more of our outstanding voting stock and any entity or person affiliated with or controlling or controlled by such entity or person.

Amendment of Certificate of Incorporation and Bylaws

The Delaware General Corporation Law provides generally that the affirmative vote of a majority of the shares entitled to vote on any matter is required to amend a corporation ’ s certificate of incorporation or bylaws, unless a corporation’ s certificate of incorporation or bylaws, as the case may be, requires a greater percentage. Our bylaws may be amended or repealed by a majority vote of our Board or the affirmative vote of the holders of at least 75% of the voting power of our capital stock issued and outstanding and entitled to vote on the matter.

S-19

Table of Contents

Limitation of Liability and Indemnification of Officers and Directors

Our certificate of incorporation limits the personal liability of directors for breach of fiduciary duty to the maximum extent permitted by the Delaware General Corporation Law. Our certificate of incorporation provides that no director will have personal liability to us or to our stockholders for monetary damages for breach of fiduciary duty or other duty as a director. However, these provisions do not eliminate or limit the liability of any of our directors:

•

for any breach of their duty of loyalty to us or our stockholders;

•

for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law;

•

for voting or assenting to unlawful payments of dividends or other distributions; or

•

for any transaction from which the director derived an improper personal benefit.

Any amendment to or repeal of these provisions will not eliminate or reduce the effect of these provisions in respect of any act or failure to act, or any cause of action, suit or claim that would accrue or arise prior to any amendment or repeal or adoption of an inconsistent provision. If the Delaware General Corporation Law is amended to provide for further limitations on the personal liability of directors of corporations, then the personal liability of our directors will be further limited to the greatest extent permitted by the Delaware General Corporation Law.

In addition, our certificate of incorporation provides that we must indemnify our directors and officers and we must advance expenses, including attorneys ’ fees, to our directors and officers in connection with legal proceedings, subject to limited exceptions.

Notice of Share Ownership

Our bylaws contain a provision requiring any beneficial owner of three percent or more of our outstanding common stock to notify us of his or her stockholdings, as well as of any change in his or her beneficial ownership of one percent or more of our outstanding common stock. Our bylaws do not provide for any specific remedy in the event a stockholder does not comply with this provision. We do not intend to make any such information public, unless required by law or the rules of the SEC or the NASDAQ Capital Market.

Authorized but Unissued Shares

Our authorized but unissued shares of common stock and preferred stock are available for future issuance without stockholder approval, subject to any limitations imposed by the listing standards of the NASDAQ Capital Market. These additional shares may be used for a variety of corporate finance transactions, acquisitions and employee benefit plans. The existence of authorized but unissued and unreserved common stock and preferred stock could make it more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise.

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is Computershare Trust Company, N.A. Its address is 250 Royall Street, Canton, MA 02021-1011, and its telephone number is 1-800-662-7232.

Our common stock is listed on the NASDAQ Capital Market under the symbol “ OPTT.”

PLAN OF DISTRIBUTION

Placement Agency Agreement

Pursuant to a Placement Agency Agreement by and between us and Aegis Capital Corp. (the “Placement Agent”), the Placement Agent has agreed to act as our exclusive placement agent in this offering. The Placement Agent is not purchasing or selling any of the shares of common stock, nor is it required to arrange for the purchase and sale of any specific number or dollar amount of the shares, but has agreed to use its “best efforts” to arrange for the sale of the shares offered by us. Therefore, we may not sell the entire amount of the shares being offered. In determining the offering price for the shares of common stock that each purchaser of our common stock would receive, the Company, based upon its discussions with the Placement Agent, considered a number of factors including, but not limited to, the current market price of our common stock, trading prices of our common stock over a period of time, the amount of liquidity and volatility of our common stock and current economic and market conditions. The Placement Agency Agreement provides that the obligations of the Placement Agent are subject to certain conditions precedent, including, among other things, the absence of any material adverse change in our business and the receipt of certain opinions, letters and certificates from us or our counsel. In connection with this offering, the Placement Agent may retain sub-agents and selected dealers. The foregoing does not purport to be a complete statement of the terms and conditions of the Placement Agency Agreement. A copy of the Placement Agency Agreement is included as an exhibit to our current report on Form 8-K that will be filed with the SEC and incorporated by reference into the registration statement of which this prospectus supplement forms a part.

We currently anticipate that the closing of this offering will occur on or about October 23, 2017. On the closing date, the following will occur:

●

we will receive funds in the amount of the aggregate purchase price;

●

the Placement Agent will receive the placement agent fees in accordance with the terms of the Placement Agency Agreement; and

●

the shares of our common stock purchased by investors in this offering will be issued to DTC in street name and credited to each investors account at each such investors brokerage firm.

Fees and Expenses

We have agreed to pay the Place ment Agent a cash fee equal to 6.5% of the gross proceeds of this offering. We have also agreed to reimburse the Placement Agent for fees and expenses of its counsel up to $60,000, which will be payable at the closing of the offering.

The following table shows the per share and total Placement Agent’s commissions we will pay to the Placement Agent in connection with the sale of the shares offered pursuant to this prospectus supplement assuming the purchase of the $ million maximum amount of shares of common stock in this offering:

Placement Agent's fees per share of common stock		$
Placement Agent ’s aggregate fees		$
Maximum offering amount		$

S-21

Table of Contents

Because there is no minimum offering amount required as a condition to the closing in this offering, the actual total offering commissions, if any, are not presently determinable and may be substantially less than the maximum amount set forth above.

We have agreed to indemnify the Placement Agent against certain liabilities, including liabilities under the Securities Act, as amended. We may also be required to contribute to payments the placement agent may be required to make in respect of such liabilities.

The Placement Agent is an underwriter within the meaning of Section 2(a)(11) of the Securities Act and any commissions received by it and any profit realized on the sale of the securities by them while acting as principal may be deemed to be underwriting discounts or commissions under the Securities Act. The Placement Agent is required to comply with the requirements of the Securities Act, as amended, and the Exchange Act, including, without limitation, Rule 10b-5 and Regulation M under the Exchange Act.

OCEAN POWER TECHNOLOGIES, INC.

We are developing and seeking to commercialize proprietary systems that generate electricity by harnessing the renewable energy of ocean waves. Our PowerBuoy® systems use proprietary technologies to convert the mechanical energy created by the rising and falling of ocean waves into electricity. We currently continue to develop our PowerBuoy line, which consists of our autonomous PowerBuoy system. Since fiscal 2002, the U.S. Navy and other government agencies have accounted for a significant portion of our revenues. These revenues were largely for the support of our product development efforts. Our goal, over time, is that an increased portion of our revenues be from the sale of products and services, as compared to revenue to support our product development efforts. As we continue to advance our proprietary technologies and develop our products, we expect to have a net use of cash from operating activities unless and until we achieve positive cash flow from the planned commercialization of our products and services.

Our principal executive offices are located at 1590 Reed Road, Pennington, New Jersey 08534, and our telephone number is (609) 730-0400. The Company was incorporated in New Jersey in 1984 and reincorporated in Delaware in 2007. We maintain a website at www.oceanpowertechnologies.com where general information about us is available. We are not incorporating the contents of the website into this prospectus supplement or the accompanying base prospectus.

RISK FACTORS

Investing in our securities involves substantial risk. You should carefully consider the risk factors contained in our most recent Annual Report on Form 10-K and our subsequent Quarterly Reports on Form 10-Q, which are incorporated by reference herein, and the other information contained in this prospectus, as updated by our subsequent filings under the Securities Exchange Act of 1934, and the risk factors and other information contained in the applicable prospectus supplement before acquiring any of such securities. These risks could have a material adverse effect on our business, results of operations or financial condition and cause the value of our securities to decline. You could lose all or part of your investment.

This prospectus and any prospectus supplement also contain or incorporate by reference forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in the forward-looking statements as a result of certain factors, including the risk factors faced by us described or incorporated by reference in this prospectus or any prospectus supplement. See “Cautionary Statement Regarding Forward-Looking Information.”

USE OF PROCEEDS

We do not currently know the number or types of securities that ultimately will be sold pursuant to this prospectus or the prices at which such securities will be sold. Unless otherwise specified in a prospectus supplement accompanying this prospectus, we intend to use the net proceeds of any sale of securities under this prospectus for any combination of working capital, capital expenditures, and general business purposes, including additional development and deployments of our PowerBuoy systems. Until we use the net proceeds in the manner described above, we may temporarily use them to make short-term investments.

DESCRIPTION OF OUR CAPITAL STOCK

The following is a general description of our capital stock. The terms of our certificate of incorporation and bylaws are more detailed than the general information provided below. You should read our certificate of incorporation and bylaws, which are incorporated by reference as exhibits to the registration statement of which this prospectus forms a part.

Authorized and Outstanding Capital Stock

The following description of our capital stock and provisions of our certificate of incorporation and bylaws are summaries and are qualified by reference to our certificate of incorporation and bylaws, which have been incorporated by reference as exhibits to the registration statement of which this prospectus forms a part.

Our authorized capital stock consists of 50,000,000 shares of common stock, par value $0.001 per share, and 5,000,000 shares of preferred stock, par value $0.001 per share, all of which are undesignated.

As of January 31, 2016, there were 1,924,234 shares of common stock issued and outstanding, and no shares of preferred stock were issued or outstanding.

Common Stock

Holders of common stock are entitled to one vote for each share held on all matters submitted to a vote of stockholders and do not have cumulative voting rights. Accordingly, holders of a majority of the shares of common stock entitled to vote in any election of directors may elect all of the directors standing for election. Holders of common stock are entitled to receive proportionately any dividends as may be declared by our board of directors, subject to any preferential dividend rights of outstanding preferred stock. Upon our liquidation, dissolution or winding up, the holders of common stock are entitled to receive proportionately our net assets available after the payment of all debts and other liabilities and subject to the prior rights of any outstanding preferred stock. Holders of common stock have no preemptive, subscription, redemption or conversion rights. Our outstanding shares of common stock are, and the shares offered by us in this offering will be, when issued and paid for, fully paid and nonassessable. The rights, preferences and privileges of holders of common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of preferred stock that we may designate and issue in the future.

Preferred Stock

Under the terms of our certificate of incorporation, our board of directors is authorized to issue shares of preferred stock in one or more series without stockholder approval. Our board of directors has the discretion to determine the rights, preferences, privileges and restrictions, including voting rights, dividend rights, conversion rights, redemption privileges and liquidation preferences, of each series of preferred stock.

-3-

Table of Contents

Authorizing our board of directors to issue preferred stock and determine its rights and preferences has the effect of eliminating delays associated with a stockholder vote on specific issuances. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions, future financings and other corporate purposes, could have the effect of making it more difficult for a third party to acquire, or could discourage a third party from seeking to acquire, a majority of our outstanding common stock.

Anti-Takeover Effects of Delaware Law; Our Certificate of Incorporation and Our Bylaws

Removal of Directors

Our certificate of incorporation and our bylaws provide that directors may be removed only for cause and only by the affirmative vote of the holders of 75% of our shares of capital stock present in person or by proxy and entitled to vote. Under our certificate of incorporation and bylaws, any vacancy on our board of directors, including a vacancy resulting from an enlargement of our board of directors, may be filled only by vote of a majority of our directors then in office.

Stockholder Action by Written Consent; Special Meetings

Advance Notice Requirements for Stockholder Proposals

Our bylaws establish an advance notice procedure for stockholder proposals to be brought before an annual meeting of stockholders, including proposed nominations of persons for election to the board of directors. Stockholders at an annual meeting may only consider proposals or nominations specified in the notice of meeting or brought before the meeting by or at the direction of the board of directors or by a stockholder of record on the record date for the meeting, who is entitled to vote at the meeting and who has delivered to our secretary a timely written notice in proper form of the stockholder ’s intention to bring such business before the meeting. These provisions could have the effect of delaying until the next stockholder meeting stockholder actions that are favored by the holders of a majority of our outstanding voting securities.

Delaware Business Combination Statute

We are subject to Section 203 of the Delaware General Corporation Law. Subject to certain exceptions, Section 203 prevents a publicly held Delaware corporation from engaging in a “business combination” with any “interested stockholder” for three years following the date that the person became an interested stockholder, unless the interested stockholder attained such status with the approval of our board of directors or unless the business combination is approved in a prescribed manner. A “business combination” includes, among other things, a merger or consolidation involving us and the “interested stockholder” and the sale of more than 10% of our assets. In general, an “interested stockholder” is any entity or person beneficially owning 15% or more of our outstanding voting stock and any entity or person affiliated with or controlling or controlled by such entity or person.

-4-

Table of Contents

Amendment of Certificate of Incorporation and Bylaws

The Delaware General Corporation Law provides generally that the affirmative vote of a majority of the shares entitled to vote on any matter is required to amend a corporation ’s certificate of incorporation or bylaws, unless a corporation’s certificate of incorporation or bylaws, as the case may be, requires a greater percentage. Our bylaws may be amended or repealed by a majority vote of our board of directors or the affirmative vote of the holders of at least 75% of the voting power of our capital stock issued and outstanding and entitled to vote on the matter.

Limitation of Liability and Indemnification of Officers and Directors

●

for any breach of their duty of loyalty to us or our stockholders;

●

for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law;

●

for voting or assenting to unlawful payments of dividends or other distributions; or

●

for any transaction from which the director derived an improper personal benefit.

Notice of Share Ownership

Our bylaws contain a provision requiring any beneficial owner of three percent or more of our outstanding common stock to notify us of his or her shareholdings, as well as of any change in his or her beneficial ownership of one percent or more of our outstanding common stock. Our bylaws do not provide for any specific remedy in the event a stockholder does not comply with this provision. We do not intend to make any such information public, unless required by law or the rules of the SEC or The NASDAQ Capital Market.

Authorized But Unissued Shares

The authorized but unissued shares of common stock and preferred stock are available for future issuance without stockholder approval, subject to any limitations imposed by the listing standards of The NASDAQ Capital Market. These additional shares may be used for a variety of corporate finance transactions, acquisitions and employee benefit plans. The existence of authorized but unissued and unreserved common stock and preferred stock could make it more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise.

Transfer Agent and Registrar

The transfer agent and registrar for the common stock is Computershare Trust Company, N.A.

Listing on the NASDAQ Global Market

DESCRIPTION OF DEBT SECURITIES

The following is a general description of the debt securities that we may issue from time to time. The particular terms relating to each debt security, which may be different from or in addition to the terms described below, will be set forth in a prospectus supplement relating to such securities.

The debt securities will be our direct obligations. The senior debt securities will rank equally with all of our other senior and unsubordinated debt. The senior subordinated debt securities will have a junior position to all of our senior debt, which is generally defined in both the subordinated debt indenture and senior subordinated debt indenture to include all debt other than debt that is expressly subordinated to or pari passu with the subordinated debt securities or senior subordinated debt securities, as the case may be. The subordinated debt securities will have a junior position to all of our senior debt and all of our senior subordinated debt. The senior debt securities will be issued under a senior debt indenture, the senior subordinated debt securities will be issued under a senior subordinated debt indenture, and the subordinated debt securities will be issued under a subordinated debt indenture. The indentures will be qualified under the Trust Indenture Act of 1939. The type and terms of the debt securities we offer under this prospectus may be limited by the other debt instruments to which we are a party at the time of the offering.

Any securities we issue will be structurally subordinated to the indebtedness and other liabilities, if any, of our subsidiaries, including claims of our subsidiaries ’ creditors, and any taxing authorities. Any claims we have as an unsecured creditor of one of our subsidiaries would be subordinate to any security interest in the assets of that subsidiary and any indebtedness of that subsidiary senior to the indebtedness held by us.

We have summarized below the material provisions of the three indentures. The summary is not complete and is subject in all respects to the provisions of and is qualified in its entirety by reference to the forms of indentures, which are filed as exhibits and incorporated by reference into the registration statement of which this prospectus forms a part. The prospectus supplement relating to the applicable issuance of debt securities will describe any significant differences between the indentures and the summary below. The forms of senior indenture, senior subordinated indenture and subordinated indenture are substantially the same, except for certain covenants of ours and provisions relating to subordination. You should read the indentures for provisions that may be important to you. The forms of indentures may be supplemented or revised in connection with the filing of a prospectus supplement with respect to a particular series of debt securities and such later version will govern any debt securities issued in conjunction with that prospectus supplement.

Terms Applicable to All Debt Securities

No Limit on Debt Amounts . The indentures do not limit the amount of debt that can be issued under the indentures. These amounts will be set from time to time by our board of directors.

Prospectus Supplements . The prospectus supplement relating to a series of debt securities will summarize the specific terms of such debt securities and the related offering including, with respect to each series of debt securities, some or all of the following, as well as any other material terms of the debt securities:

●

the title of the securities of the series (which title will distinguish the securities of the series from all other series of securities);

●

any limit upon the aggregate principal amount of the securities of the series which may be authenticated and delivered (which limit will not pertain to securities authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other securities of the series or any securities that are deemed never to have been authenticated and delivered);

●

Upon issuance of a registered global security, the depositary will credit, on its book-entry registration and transfer system, participants ’ accounts with the principal amount of the debt security beneficially owned by such participants. Each person owning a beneficial interest in a registered global security will have to rely on the procedures of the depositary for such registered global security to exercise any rights of a holder under the applicable indenture.

Table of Contents

A series of debt securities may be issued under the relevant indenture as original issue discount securities, which are securities that are offered and sold at a discount from their stated principal amount. In addition, debt securities offered and sold at their stated principal amount may under some circumstances, pursuant to applicable Treasury Regulations, be treated as issued at an original issue discount for federal income tax purposes. Federal income tax consequences and other special considerations applicable to any such original issue discount securities (or other debt securities treated as issued at an original issue discount) will be described in the prospectus supplement relating to those securities.

Covenants . We will agree in the indentures with respect to any series of debt securities to:

●

pay the principal, interest and any premium on the securities of the series when due;

●

maintain an office or agency where the securities of the series may be surrendered for registration of transfer, exchange, payment or conversion (if the debt securities are convertible) and where notices and demands to or upon us in respect of the securities of the series and the relevant indenture may be served;

●

prepare and file or deliver certain reports, as more fully specified in the relevant indenture, with the SEC, the trustee under the relevant indenture, and/or registered holders of the securities of the series, as the case may be;

●

deliver to the trustee under the relevant indenture, as more fully specified in that indenture, officers ’ certificates relating to our compliance under the relevant indenture and the occurrence of any default or event of default under that indenture; and

●

unless our board of directors determines that it is no longer desirable in the conduct of our business and that there will be no adverse impact in any material respect to the holders of the securities of the series, subject to those exceptions as more fully specified in the relevant indenture, do or cause to be done all things necessary to preserve and keep in full force and effect our existence as a corporation and our rights (charter and statutory rights) and franchises.

Consolidation, Merger and Sale of Assets . We will agree in the indentures with respect to any series of debt securities that we will not consolidate with or merge into any other entity or transfer all or substantially all of our assets unless:

●

we are the surviving entity; or

●

the successor or surviving entity assumes all of our obligations under the securities of such series and the indentures pursuant to supplemental indentures in forms reasonably satisfactory to the trustee(s) under the relevant indentures and is organized or existing under the laws of the United States of America and any state thereof or the District of Columbia; and, in either case,

●

immediately after giving effect to such transaction, no event of default under the relevant indenture will have happened and be continuing.

Upon any such consolidation, merger or transfer of all or substantially all of our assets, the successor will be substituted for us under the indenture and we will be relieved of all obligations and covenants under the indenture with respect to such series of debt securities, except in the case of a lease of all or substantially all of our assets.

Table of Contents

Satisfaction and Discharge . Upon our request, the relevant indenture will no longer be effective with respect to any series of debt securities for all but certain specified purposes if either:

●

all outstanding securities of that series have been delivered to the trustee for cancellation, we have paid all sums payable in respect of that series and we have delivered to the trustee a certificate and opinion of legal counsel that all conditions precedent to satisfaction and discharge have been fulfilled; or

●

the only securities that remain outstanding have, or within one year will, become due and payable or are to be called for redemption, we have deposited with the trustee funds that are sufficient to make all future payments, no default or event of default will have occurred and be continuing on the date of that deposit, we have paid all other sums payable in respect of that series, and we have delivered to the trustee a certificate and opinion of counsel that all conditions precedent to satisfaction and discharge have been fulfilled.

Legal Defeasance and Covenant Defeasance . Under each indenture, we may elect with respect to a series of debt securities, at our option and subject to the satisfaction of the conditions described below, either:

●

to be deemed to have paid and discharged the entire indebtedness represented by the outstanding securities of the applicable series and to have satisfied all of our other obligations under the securities of the applicable series and under the provisions of the relevant indenture, which we refer to as legal defeasance; or

●

to be released from some of our obligations under the relevant indenture, which we refer to as covenant defeasance.

We can exercise legal or covenant defeasance with respect to any series of debt securities if the following conditions are met:

●

we irrevocably deposit with the applicable indenture trustee (or another trustee meeting certain eligibility requirements and agreeing to be bound by the applicable provisions of the relevant indenture), in trust, for the benefit of the holders of the applicable series of debt securities:

●

cash in United States dollars;

●

non-callable and non-redeemable direct obligations of the United States of America or of an agency or instrumentality controlled or supervised by the United States of America, in each instance, the payment of which is unconditionally guaranteed as a full faith and credit obligation of the United States of America; or

●

a combination of the foregoing that, in each case, is sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, interest and premium, if any, on the outstanding debt securities of the applicable series on their stated maturity or applicable redemption date, as the case may be, and any mandatory sinking fund payments applicable to that particular series of debt securities on the day on which the payments are due;

●

we deliver to the trustee an opinion of counsel confirming that the holders of the outstanding securities of the applicable series will not recognize income, gain or loss for federal income tax purposes as a result of the defeasance;

●

no default or event of default shall have occurred and be continuing on the date of the deposit of the amounts to be held in trust for the benefit of the holders (other than a default or event of default resulting from the borrowing of funds to be applied to the deposit) or in the case of any insolvency-related defaults, at any time in the period ending on the 91st day after the date of the deposit (or greater period of time in which any such deposit of trust funds may remain subject to bankruptcy or insolvency laws that apply to the deposit by us); and

-10-

Table of Contents

●

we deliver to the trustee an officers ’ certificate and an opinion of counsel, each stating that all conditions precedent provided for or relating to legal defeasance or covenant defeasance, as the case may be, have been complied with.

After satisfying the conditions for legal defeasance, the debt securities of the applicable series will be deemed outstanding only for limited purposes as more fully set forth in the relevant indenture. After legal defeasance, the holders of outstanding debt securities of the applicable series will have to rely solely on the deposits we make to the trust for repayment of such debt securities.

After satisfying the conditions for covenant defeasance, the debt securities of the applicable series will be deemed not outstanding for the purposes of the covenants from which we have been released, but will continue to be deemed outstanding for all other purposes under the relevant indenture.

The prospectus supplement relating to a series of debt securities may describe additional provisions, if any, permitting legal defeasance or covenant defeasance, and any modifications to the provisions described above, with respect to the debt securities of a particular series.

Information Concerning the Trustee . The prospectus supplement relating to a series of debt securities will include information concerning the trustee under the applicable indenture and our relationship with the trustee at the time any debt securities are offered. We may also maintain bank accounts, borrow money and have other banking or investment banking relationships with the trustee, or its affiliates, in the ordinary course of business.

Global Securities . The registered debt securities may be issued in the form of one or more fully registered global securities that will be deposited with and registered in the name of a depositary or in the name of a nominee for a depositary identified in the prospectus supplement relating to such debt securities. The specific terms of the depositary arrangement with respect to any debt securities to be represented by a registered global security will be described in the prospectus supplement relating to such debt securities. We anticipate that the description below will apply to all depositary arrangements.

Ownership of beneficial interests in a registered global security will be limited to persons that have accounts with the depositary for such registered global security (“participants”) or persons that may hold interests through participants. Upon the issuance of a registered global security, the depositary will credit, on its book-entry registration and transfer system, the participants ’ accounts with the principal amounts of the debt securities represented by the registered global security beneficially owned by such participants. Ownership of beneficial interests in such registered global security will be shown on, and the transfer of such ownership interests will be effected only through, records maintained by the depositary for such registered global security or on the records of participants for interests of persons holding through participants.

So long as the depositary for a registered global security, or its nominee, is the registered owner of a registered global security, the depositary or the nominee will be considered the sole owner or holder of the debt securities represented by the registered global security for all purposes. Except as set forth below, owners of beneficial interests in a registered global security will not:

●

be entitled to have the debt securities represented by such registered global security registered in their names;

●

receive or be entitled to receive physical delivery of such debt securities in definitive forms; or

●

be considered the owners of record or holders of the debt securities.

Each person owning a beneficial interest in a registered global security will have to rely on the procedures of the depositary for such registered global security and, if such person is not a participant, on the procedures of the participant through which such person owns its interest, to exercise any rights of a holder under the applicable indenture. We understand that under existing industry practices, if we were to request any action of holders, or if an owner of a beneficial interest in a registered global security desired to take any action that a holder is entitled to take under the applicable indenture, the depositary would authorize the participants holding the relevant beneficial interests to take such action, and such participants would authorize beneficial owners owning through such participants to take such action.

-11-

Table of Contents

Principal of, interest and premium, if any, on debt securities represented by a registered global security registered in the name of a depositary or its nominee will be made to such depositary or its nominee, as the case may be, as the registered owner of such registered global security. Neither we nor the trustee will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in such registered global security.

We expect that the depositary for any debt securities represented by a registered global security, upon receipt of any payment of principal, interest or premium, if any, will immediately credit participants ’ accounts with such payments in amounts proportionate to their respective beneficial interests in such registered global security as shown on the records of such depositary. We also expect that payments by participants to owners of beneficial interests in such a registered global security held by the participants will be governed by standing customer instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in “street name.”

If the depositary notifies us that it is unwilling or unable to continue as depositary for the global security or if at any time the depositary ceases to be a clearing agency registered under the Securities Exchange Act of 1934, and such registration as a clearing agency is required by applicable law or regulation to serve as a depositary, and, in either situation, we do not appoint a successor depositary within 90 days, we will issue debt securities in certificated form in exchange for the global security. In addition, we may at any time in our sole discretion decide not to have any debt securities represented by a global security. In such event we will issue debt securities in certificated form in exchange for the global security. The debt securities in certificated form will be in the same minimal denominations and be of the same aggregate outstanding principal amount and tenor as the portion of each global security to be exchanged.

Any debt securities issued in certificated form in exchange for a global security will be registered in such name or names as the depositary shall instruct the relevant trustee. We expect that such instructions will be based upon directions received by the depositary from participants with respect to ownership of beneficial interests in such registered global security.

If provided in a prospectus supplement relating to a series of debt securities, the debt securities of that series also may be issued in the form of one or more global securities that will be deposited with a common depositary identified in the prospectus supplement. The specific terms and procedures, including the specific terms of the depositary arrangement, with respect to any portion of a series of debt securities to be represented by a global security will be described in the prospectus supplement relating to that series.

Form, Exchange, Transfer . Unless otherwise specified in a prospectus supplement relating to a series of debt securities, debt securities will be issued in global form with accompanying book-entry procedures as outlined above. They also may be issued in registered form without coupons.

A holder of debt securities of any series may exchange the debt securities for other debt securities of the same series, in any authorized denomination and with the same terms and aggregate principal amount. The securities are transferable at the corporate trust office or corporate trust agency office of the trustee or at any transfer agent designated by us for that purpose. No service charge will be made for any transfer or exchange of the debt securities, but we may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection with a transfer or exchange and any expenses payable in connection with any registration of transfer or exchange of debt securities, other than exchanges not involving any transfer, such as the issuance of definitive securities in replacement of temporary securities or the issuance of new securities upon surrender of a security that is redeemed in part.

Particular Terms of the Senior Debt Securities

Ranking of Senior Debt Securities . Unless otherwise specified in a prospectus supplement relating to a series of senior debt securities, the senior debt securities will constitute part of our senior debt and rank equally with all our other senior debt that is unsecured (and will effectively rank junior to any secured debt). In addition to senior debt securities offered under this prospectus, senior debt includes obligations under any credit facilities with banks or other institutional lenders. The senior debt securities will be senior to our senior subordinated debt and subordinated debt. Our obligations under the senior debt securities will be structurally subordinated to certain obligations of our subsidiaries.

Events of Default . The following, among others, are events of default under a series of senior debt securities:

●

we fail to pay the principal, premium, if any, or any sinking fund payment on any securities of that series when due;

●

we fail to pay interest on any securities of that series when due and that failure continues for a period of 30 days;

●

upon exercise of a holder ’s conversion right, we fail to deliver conversion consideration in accordance with the indenture;

●

we fail to comply with our obligations in the event of a consolidation, merger or sale of assets, as set forth in the indenture;

●

we fail to observe or perform any other covenant or agreement in the senior indenture for the benefit of that series (other than a covenant or agreement with respect to which a failure to observe or perform is dealt with otherwise in the senior indenture or is expressly included in the senior indenture solely for the benefit of a series of debt securities other than such series of debt securities) and that failure continues for 90 days after we receive notice to comply from the trustee or holders of at least 25% in aggregate principal amount of the outstanding senior debt securities;

●

we fail to pay our indebtedness or to pay or discharge certain final judgments against us, as set forth in the indenture; and

●

certain events of bankruptcy or insolvency occur, whether voluntary or not.

The indenture and the prospectus supplement relating to a series of senior debt securities may describe additional or different events of default that apply to that series. An event of default with respect to one series of senior debt securities will not necessarily constitute an event of default with respect to any other series of senior debt securities.

If a default or an event of default occurs and is continuing, the trustee will mail to the holders of senior debt securities of the affected series a notice to that effect within 90 days after the default occurs, if a responsible officer of the trustee under the indenture has actual knowledge of the default or event of default. Except in the case of a default in the payment of principal or interest, the trustee under the senior indenture may withhold notice if, and so long as, a committee of the trustee ’s responsible officers in good faith determines that withholding the notice is in the interests of the holders.

If an event of default with respect to one or more series of senior debt securities occurs and is continuing, the trustee or the holders of at least 25% in aggregate principal amount of the then outstanding senior debt securities of all series with respect to which the event of default occurs and is continuing, treating all those series as a single class, may declare all the principal of, accrued and unpaid interest or premium (or a lesser amount as may be provided for in the senior debt securities of the series), if any, of all the senior debt securities of those series to be immediately due and payable. The holders of a majority in aggregate principal amount of the then outstanding senior debt securities of all series covered by such declaration may annul or rescind the declaration and any related payment default that resulted from the declaration but not any other payment default. Certain events of bankruptcy and insolvency will result in all outstanding series of senior debt securities becoming due and payable immediately without any further action on the part of the trustee or the holders.

-13-

Table of Contents

The senior indenture entitles the trustee to be indemnified by the holders before proceeding to exercise any right or power at the request of any of the holders.

The holders of a majority in principal amount of the outstanding senior debt securities of all series with respect to which an event of default occurs and is continuing, treating all those series as a single class, may direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust power conferred on it, except that:

●

the direction cannot conflict with any law or regulation or the indenture;

●

the trustee may take any other action deemed proper by the trustee that is not inconsistent with the direction; and

●

the trustee need not take any action that might subject it to personal liability or be unduly prejudicial to the holders of the senior debt securities not joining in the action.

A holder may pursue a remedy directly under the senior indenture or a particular series of senior debt securities but, before doing so, the following must occur:

●

the holder must give to the trustee written notice that an event of default has occurred and is continuing;

●

the holders of at least 25% in principal amount of the then outstanding senior debt securities of all affected series, treating all those series as a single class, must make a written request to the trustee to pursue the remedy;

●

the holder, or holders, must offer and, if requested, provide to the trustee an indemnity satisfactory to the trustee against any loss, liability or expense from the taking of the action;

●

the trustee does not comply with the request within 60 days after receipt of the request and offer and, if requested, the provision of indemnity; and

●

during the 60-day period, the holders of a majority in principal amount of the then outstanding senior debt securities of all those series, treating all those series as a single class, do not give the trustee a direction inconsistent with the written request.

However, holders have an absolute right to receipt of principal, interest or premium, if any, on or after the respective due dates and to institute suit for the enforcement of those payments. The right of a holder of senior debt securities to bring suit for the enforcement of any payments of principal, interest or premium, if any, on senior debt securities on or after the respective due dates may not be impaired or affected without the consent of that holder.

The holders of a majority in principal amount of the senior debt securities then outstanding of all affected series, treating all such series as a single class, may, by notice to the trustee on behalf of all holders of the senior debt securities of all those series, waive any past defaults, except:

●

a continuing default in payment of the principal of, interest or premium, if any, on, or any sinking fund payment on, senior debt securities of the series;

●

a continuing default in respect of a covenant or provision of the indenture that cannot be amended or modified without the consent of each holder of senior debt securities affected;

-14-

Table of Contents

●

one arising from a failure to pay or deliver to converting holders consideration due upon conversion; and

●

in respect of a covenant or provision that under the senior indenture cannot be modified or amended without the consent of the holder of each outstanding note affected.

We periodically will file statements with the trustees regarding our compliance with covenants in the senior indenture.

Modifications and Amendments . Except as provided below, or more fully specified in the senior indenture and described in the applicable prospectus supplement, the senior indenture may be amended or supplemented by us and the trustee with the consent of holders of a majority in principal amount of all series of senior debt securities affected by the amendment or supplement, treating all such series as a single class. In addition, the record holders of a majority in principal amount of the outstanding senior debt securities of all series affected by the waiver, treating all such series as a single class, may, with respect to those series, waive defaults under, or compliance with, the provisions of the senior indenture. Some amendments or waivers, however, require the consent of each holder of any senior debt security affected. Without the consent of each affected holder, an amendment or waiver regarding a series of senior debt securities may not:

●

change the maturity date, or the payment date of any installment interest on, any securities;

●

reduce the principal amount of, or interest on, any securities;

●

change the place, manner or currency of payment of principal of, or interest on, any securities;

●

impair the right to institute a suit for the enforcement of any payment on, or with respect to, or of the conversion of, any security;

●

change the ranking of the securities in a manner adverse to the holders of securities;

●

adversely affect the right of holders of securities to convert their securities in accordance with the indenture, or reduce the amount of consideration due upon conversion;

●

reduce the percentage in aggregate principal amount of outstanding securities whose holders must consent to a modification or amendment of the indenture or the securities;

●

reduce the percentage in aggregate principal amount of outstanding securities whose holders must consent to a waiver of compliance with any provision in the indenture, or the securities or a waiver of any default or event of default; or

●

modify the applicable provisions of the indenture, except to increase the percentage required for modification or waiver or to provide for the consent of each affected holder.

We and the trustee under the senior indenture may amend or supplement the senior indenture or the senior debt securities issued thereunder without notice to or the consent of any holder to:

●

provide for the assumption by a successor company of the Company's obligations under the securities and the indenture;

●

add guarantees with respect to the securities;

●

secure the securities;

●

add to the covenants for the benefit of the holders or surrender any right or power conferred upon the Company;

●

make any change, including to cure any omission, ambiguity, manifest error or defect or to correct any inconsistency in the indenture that does not adversely affect the rights of any holder in any material respect;

●

comply with any requirement of the SEC in connection with the qualification of the indenture under the Trust Indenture Act or with the rules of any applicable securities depositary;

●

provide for the issuance of and establish the form and terms and conditions of the securities of any series, to establish the form of any certifications required to be furnished, or to add to the rights of the holders of any series of securities;

●

add additional events of default;

●

evidence the acceptance or appointment of a successor trustee or to add an additional trustee or agent in accordance with the indenture; or

●

conform the provisions of the indenture and the securities to the "Description of Notes" section as set forth in a preliminary prospectus supplement related to the offering and sale of the securities, as supplemented by the related pricing term sheet.

Particular Terms of the Senior Subordinated Debt Securities

Ranking of Senior Subordinated Debt Securities . As described below, the senior subordinated debt securities will rank senior to any subordinated debt securities and will be subordinated and junior in right of payment to any senior debt securities issued by us, as well as certain other indebtedness incurred by us to the extent set forth in the applicable indenture and described in the prospectus supplement relating to a series of senior subordinated debt securities. Unless the prospectus supplement relating to a series of senior subordinated debt securities indicates otherwise, the following description will apply to our senior subordinated debt securities.

Subordination . Our obligations under the senior subordinated debt securities will be subordinated in right of payment to our obligations under our senior debt and will be structurally subordinated to certain obligations of our subsidiaries, including claims payable. In the indenture relating to the senior subordinated securities, we will agree not to create, incur or otherwise be liable for any other indebtedness that ranks junior to the senior debt in right of payment, but senior to the senior subordinated securities. For this purpose, “senior debt” generally includes any indebtedness that does not expressly provide that it is on a parity with or subordinated in right of payment to the senior subordinated debt securities. Specifically, senior debt includes obligations under any credit facility with banks or other institutional lenders and obligations under the senior debt securities described in this prospectus. Senior debt will not include:

●

any liability for federal, state, local or other taxes;

●

any indebtedness to any of our subsidiaries or other affiliates;

●

any trade payables;

●

any indebtedness that we may incur in violation of the senior subordinated indenture; or

●

obligations under any subordinated debt securities.

If we distribute our assets to creditors upon any dissolution, winding-up, liquidation or reorganization or in bankruptcy, insolvency, receivership or similar proceedings, we must first pay all amounts due or to become due on all senior debt before we pay the principal of, or make any other payment on, the senior subordinated debt securities. The provisions of the senior subordinated debt indenture providing these payment restrictions will not limit the right, if any, of a holder of senior subordinated debt securities to convert the debt securities into equity securities.

-16-

Table of Contents

We may not make any payment on the senior subordinated debt securities if a default in the payment of the principal, interest or premium, if any, including a default under any repurchase or redemption obligation in respect of designated senior debt, occurs and continues beyond any applicable grace period. We may not make any payment on the senior subordinated debt securities if any other default occurs and continues with respect to designated senior debt that permits holders of the designated senior debt to accelerate its maturity and the trustee receives a notice of default from any person permitted to give notice. We may not resume payments on the senior subordinated debt securities until the defaults are cured or specified time periods pass, unless the senior debt is paid in full. The provisions of the senior subordinated debt indenture providing these payment restrictions will not limit the right, if any, of a holder of senior subordinated debt securities to convert the debt securities into equity securities.

The term “designated senior debt” means our obligations under our principal bank or other institutional credit facility, if any, and any other debt expressly designated as senior debt with respect to the applicable senior subordinated debt securities.

We expect that the terms of some of our senior debt will provide that an event of default under the senior subordinated debt securities or an acceleration of their maturity will constitute an event of default under the senior debt. In that case, if the maturity of the senior subordinated debt securities is accelerated because of an event of default, we may not make any payment on the senior subordinated debt securities until we have paid all senior debt or the acceleration has been rescinded. If the payment of the senior subordinated debt securities is accelerated because of an event of default, we must promptly notify the holders of senior debt of the acceleration.

If we experience a bankruptcy, dissolution or reorganization, holders of senior debt may receive more, ratably, and holders of the senior subordinated debt securities may receive less, ratably, than our other creditors.

The indenture for senior subordinated debt securities may not limit our ability to incur additional senior debt.

Events of Default . The following, among others, are events of default under a series of senior subordinated debt securities:

●

we fail to pay the principal, premium, if any, or any sinking fund payment on any securities of that series when due;

●

we fail to pay interest on any securities of that series when due and that failure continues for a period of 30 days;

●

upon exercise of a holder ’s conversion right, we fail to deliver conversion consideration in accordance with the indenture;

●

we fail to comply with our obligations in the event of a consolidation, merger or sale of assets, as set forth in the indenture;

●

we fail to observe or perform any other covenant or agreement in the senior subordinated indenture for the benefit of that series (other than a covenant or agreement with respect to which a failure to observe or perform is dealt with otherwise in the senior subordinated indenture or is expressly included in the senior subordinated indenture solely for the benefit of a series of debt securities other than such series of debt securities) and that failure continues for 90 days after we receive notice to comply from the trustee or holders of at least 25% in aggregate principal amount of the outstanding senior subordinated debt securities;

Table of Contents

●

we fail to pay our indebtedness or to pay or discharge certain final judgments against us, as set forth in the indenture; and

●

certain events of bankruptcy or insolvency occur, whether voluntary or not.

The indenture and prospectus supplement relating to a series of senior subordinated debt securities may describe additional or different events of default that apply to that series. An event of default with respect to one series of senior subordinated debt securities will not necessarily constitute an event of default with respect to any other series of senior subordinated debt securities.

If a default or an event of default occurs and is continuing, the trustee will mail to the holders of senior subordinated debt securities of the affected series a notice to that effect within 90 days after the default occurs, if a responsible officer of the trustee under the indenture has actual knowledge of the default or event of default.

Except in the case of a default in the payment of principal or interest, the trustee under the senior subordinated indenture may withhold notice if, and so long as, a committee of the trustee ’s responsible officers in good faith determines that withholding the notice is in the interests of the holders.

If an event of default with respect to one or more series of senior subordinated debt securities occurs and is continuing, the trustee or the holders of at least 25% in aggregate principal amount of the then outstanding senior subordinated debt securities of all series with respect to which the event of default occurs and is continuing, treating all those series as a single class, may declare all the principal of, accrued and unpaid interest and premium (or such lesser amount as may be provided for in the senior subordinated debt securities of the series), if any (subject to applicable subordination provisions in the senior subordinated indenture) of all the senior subordinated debt securities of those series, to be immediately due and payable. The holders of a majority in aggregate principal amount of the then outstanding senior subordinated debt securities of all series covered by such declaration may annul and rescind the declaration and any related payment default that resulted from the declaration but not any other payment default. Certain events of bankruptcy and insolvency will result in all outstanding series of senior subordinated debt securities becoming due and payable immediately without any further action on the part of the trustee or the holders.

The senior subordinated indenture entitles the trustee to be indemnified by the holders before proceeding to exercise any right or power at the request of any of the holders.

The holders of a majority in principal amount of the outstanding senior subordinated debt securities of all series with respect to which an event of default occurs and is continuing, treating all those series as a single class, may direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust power conferred on it, except that:

●

the direction cannot conflict with any law or regulation or the indenture;

●

the trustee may take any other action deemed proper by the trustee that is not inconsistent with the direction; and

●

the trustee need not take any action that might subject it to personal liability or be unduly prejudicial to the holders of the senior subordinated debt securities not joining in the action.

A holder may pursue a remedy directly under the senior subordinated indenture or a particular series of senior subordinated debt securities but, before doing so, the following must occur:

●

the holder must give to the trustee written notice that an event of default has occurred and is continuing;

-18-

Table of Contents

●

the holders of at least 25% in principal amount of the then outstanding senior subordinated debt securities of all affected series, treating all those series as a single class, must make a written request to the trustee to pursue the remedy;

●

the holder, or holders, must offer and, if requested, provide to the trustee an indemnity satisfactory to the trustee against any loss, liability or expense from the taking of the action;

●

the trustee does not comply with the request within 60 days after receipt of the request and offer and, if requested, the provision of indemnity; and

●

during the 60-day period, the holders of a majority in principal amount of the then outstanding senior subordinated debt securities of all affected series, treating all those series as a single class, do not give the trustee a direction inconsistent with the written request.

However, holders have an absolute right to receipt of principal, interest or premium, if any, on or after the respective due dates and to institute suit for the enforcement of those payments. The right of a holder of senior subordinated debt securities to bring suit for the enforcement of any payments of principal, interest or premium, if any, on senior subordinated debt securities on or after the respective due dates, without regard to acceleration or default, may not be impaired or affected without the consent of that holder.

The holders of a majority in principal amount of the senior subordinated debt securities then outstanding of all affected series, treating all those series as a single class, may, by notice to the trustee on behalf of all holders of the senior subordinated debt securities of those series, waive any past defaults, except:

●

a continuing default in payment of the principal of, interest or premium, if any, on, or any sinking fund payment on, senior subordinated debt securities of the series;

●

a continuing default in respect of a covenant or provision of the indenture that cannot be amended or modified without the consent of each holder of senior subordinated debt securities affected;

●

one arising from a failure to pay or deliver to converting holders consideration due upon conversion; and

●

in respect of a covenant or provision that under the senior subordinated indenture cannot be modified or amended without the consent of the holder of each outstanding note affected.

We periodically will file statements with the trustees regarding our compliance with covenants in the senior subordinated indenture.

Modifications and Amendments . Except as provided below, or more fully specified in the senior subordinated indenture and described in the applicable prospectus supplement, the senior subordinated indenture may be amended or supplemented by us and the trustee with the consent of holders of a majority in principal amount of all series of senior subordinated debt securities affected by the amendment or supplement, treating all such series as a single class. In addition, the record holders of a majority in principal amount of the outstanding senior subordinated debt securities of all series affected by the waiver, treating all such series as a single class, may, with respect to those series, waive defaults under, or compliance with, the provisions of the senior subordinated indenture. Some amendments or waivers, however, require the consent of each holder of any senior subordinated debt security affected. Without the consent of each affected holder, an amendment or waiver regarding a series of senior subordinated debt securities may not:

●

change the maturity date, or the payment date of any installment interest on, any securities;

●

reduce the principal amount of, or interest on, any securities;

●

change the place, manner or currency of payment of principal of, or interest on, any securities;

●

modify the applicable provisions of the indenture, except to increase the percentage required for modification or waiver or to provide for the consent of each affected holder.

●

provide for the assumption by a successor company of the Company ’s obligations under the securities and the indenture;

Particular Terms of the Subordinated Debt Securities

Ranking of Subordinated Debt Securities . The subordinated debt securities will be subordinated and junior in right of payment to any senior debt securities and senior subordinated debt securities issued by us, as well as certain other indebtedness incurred by us to the extent set forth in the applicable indenture described in the prospectus supplement relating to a series of subordinated debt securities.

Subordination . Unless the prospectus supplement relating to a series of subordinated debt securities indicates otherwise, the subordination provisions of the subordinated debt securities will be the same as those of the senior subordinated debt securities just described, except that:

●

“Senior debt” will include our obligations under the senior subordinated debt securities, as well as under the other debt specified above, including the “designated senior debt;” and

●

different series of subordinated debt securities may rank senior to other series. In that case, our obligations under the higher-ranking series will be “senior debt” in relation to the lower-ranking series, as set forth in the prospectus supplement.

The subordinated indenture does not limit the amount of additional senior debt that we may incur. We expect from time to time to incur additional indebtedness constituting senior debt.

Events of Default . The following, among others, are events of default under a series of subordinated debt securities:

●

we fail to pay the principal, premium, if any, or any sinking fund payment on any securities of that series when due;

●

we fail to pay interest on any securities of that series when due and that failure continues for a period of 30 days;

●

upon exercise of a holder ’s conversion right, we fail to deliver conversion consideration in accordance with the indenture;

●

we fail to comply with our obligations in the event of a consolidation, merger or sale of assets, as set forth in the indenture;

●

we fail to observe or perform any other covenant or agreement in the subordinated indenture for the benefit of that series (other than a covenant or agreement with respect to which a failure to observe or perform is dealt with otherwise in the subordinated indenture or is expressly included in the subordinated indenture solely for the benefit of a series of debt securities other than such series of debt securities) and that failure continues for 90 days after we receive notice to comply from the trustee or holders of at least 25% in aggregate principal amount of the outstanding subordinated debt securities;

●

we fail to pay our indebtedness or to pay or discharge certain final judgments against us, as set forth in the indenture; and

●

certain events of bankruptcy or insolvency occur, whether voluntary or not.

The indenture and prospectus supplement relating to a series of subordinated debt securities may describe additional or different events of default that apply to that series. An event of default with respect to one series of subordinated debt securities will not necessarily constitute an event of default with respect to any other series of subordinated debt securities.

-21-

Table of Contents

If a default or an event of default occurs and is continuing, the trustee will mail to the holders of subordinated debt securities of the affected series a notice to that effect within 90 days after the default occurs, if a responsible officer of the trustee under the indenture has actual knowledge of the default or event of default. Except in the case of a default in the payment of principal or interest, the trustee under the subordinated indenture may withhold notice if, and so long as, a committee of the trustee ’s responsible officers in good faith determines that withholding the notice is in the interests of the holders.

If an event of default with respect to one or more series of subordinated debt securities occurs and is continuing, the trustee or the holders of at least 25% in aggregate principal amount of the then outstanding subordinated debt securities of all series with respect to which the event of default occurs and is continuing, treating all those series as a single class, may declare all the principal of, accrued and unpaid interest and premium (or a lesser amount as may be provided for in the subordinated debt securities of the series), if any, (subject to applicable subordination provisions in the relevant indenture) of all the subordinated debt securities of those series to be immediately due and payable. The holders of a majority in aggregate principal amount of the then outstanding subordinated debt securities of all series covered by such declaration may annul and rescind the declaration and any related payment default that resulted from the declaration but not any other payment default. Certain events of bankruptcy and insolvency will result in all outstanding series of subordinated debt securities becoming due and payable immediately without any further action on the part of the trustee or the holders.

The subordinated indenture entitles the trustee to be indemnified by the holders before proceeding to exercise any right or power at the request of any of the holders.

The holders of a majority in principal amount of the outstanding subordinated debt securities of all series with respect to which an event of default occurs and is continuing and that rank equal with each other, treating all those series as a single class, may direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust power conferred on it with respect to those series, except that:

●

the direction cannot conflict with any law or regulation or the subordinated indenture;

●

the trustee may take any other action deemed proper by the trustee that is not inconsistent with the direction; and

●

the trustee need not take any action that might subject it to personal liability or be unduly prejudicial to the holders of the subordinated debt securities not joining in the action.

A holder may pursue a remedy directly under the subordinated indenture or a particular series of subordinated debt securities but, before doing so, the following must occur:

●

the holder must give to the trustee written notice that an event of default has occurred and is continuing;

●

the holders of at least 25% in principal amount of the then outstanding subordinated debt securities of all affected series that rank equal with each other, treating all those series as a single class, must make a written request to the trustee to pursue the remedy;

●

the holder, or holders, must offer and, if requested, provide to the trustee an indemnity satisfactory to the trustee against any loss, liability or expense from the taking of the action;

●

the trustee does not comply with the request within 60 days after receipt of the request and offer and, if requested, the provision of indemnity; and

●

during the 60-day period, the holders of a majority in principal amount of the then outstanding subordinated debt securities of all those series, treating all those series as a single class, do not give the trustee a direction inconsistent with the written request.

-22-

Table of Contents

However, holders have an absolute right to receipt of principal, interest and premium, if any, on or after the respective due dates and to institute suit for the enforcement of those payments. The right of a holder of subordinated debt securities to bring suit for the enforcement of any payments of principal, interest and premium, if any, on subordinated debt securities on or after the respective due dates may not be impaired or affected without the consent of that holder.

The holders of a majority in principal amount of the then outstanding subordinated debt securities of all affected series that rank equal with each other treating all such series as a single class, may, by notice to the trustee on behalf of all holders of the subordinated debt securities of such series, waive any past defaults, except:

●

a continuing default in payment of the principal of, interest or premium, if any, on, or any sinking fund payment on, subordinated debt securities of the series;

●

a continuing default in respect of a covenant or provision of the indenture that cannot be amended or modified without the consent of each holder of subordinated debt securities affected;

●

one arising from a failure to pay or deliver to converting holders consideration due upon conversion; and

Modifications and Amendments . Except as provided below, or more fully specified in the subordinated indenture and described in the applicable prospectus supplement, the subordinated indenture may be amended or supplemented by us and the trustee with the consent of holders of a majority in principal amount of all affected series of subordinated debt securities that rank equal with each other, treating all such series as a single class. In addition, the record holders of a majority in principal amount of the outstanding subordinated debt securities of all series affected by the waiver that rank equal with each other, treating such series as a single class, may, with respect to those series, waive defaults under, or compliance with, the provisions of the subordinated indenture. Some amendments or waivers, however, require the consent of each holder of any subordinated debt security affected. Without the consent of each affected holder, an amendment or waiver regarding a series of subordinated debt securities may not:

●

change the maturity date, or the payment date of any installment interest on, any securities;

●

reduce the principal amount of, or interest on, any securities;

●

change the place, manner or currency of payment of principal of, or interest on, any securities;

●

impair the right to institute a suit for the enforcement of any payment on, or with respect to, or of the conversion of, any security;

PLAN OF DISTRIBUTION

We may sell the securities in any one or more of the following ways:

●

directly to investors, including through a specific bidding, auction or other process;

●

to investors through agents;

●

directly to agents;

●

to or through brokers or dealers;

●

to the public through underwriting syndicates led by one or more managing underwriters;

●

in “at the market” offerings, within the meaning of Rule 415(a)(4) of the Securities Act of 1933, to or through a market maker or into an existing trading market on an exchange or otherwise;

●

to one or more underwriters acting alone for resale to investors or to the public; and

●

through a combination of any such methods of sale.

If we sell securities to a dealer acting as principal, the dealer may resell such securities at varying prices to be determined by such dealer in its discretion at the time of resale without consulting with us and such resale prices may not be disclosed in the applicable prospectus supplement.

Any underwritten offering may be on a best efforts or a firm commitment basis. We may also offer securities through subscription rights distributed to our stockholders on a pro rata basis, which may or may not be transferable. In any distribution of subscription rights to stockholders, if all of the underlying securities are not subscribed for, we may then sell the unsubscribed securities directly to third parties or may engage the services of one or more underwriters, dealers or agents, including standby underwriters, to sell the unsubscribed securities to third parties.

Sales of the securities may be effected from time to time in one or more transactions, including negotiated transactions:

●

at a fixed price or prices, which may be changed;

●

at market prices prevailing at the time of sale;

●

at prices related to prevailing market prices; or

●

at negotiated prices.

Any of the prices may represent a discount from the then-prevailing market prices.

In connection with the sale of any of the securities, underwriters or agents may receive compensation from us in the form of underwriting discounts or commissions and may also receive compensation from purchasers of the securities, for whom they may act as agents, in the form of discounts, concessions or commissions. Underwriters may sell the securities to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from the purchasers for whom they may act as agents. Discounts, concessions and commissions may be changed from time to time. Dealers and agents that participate in the distribution of the securities may be deemed to be underwriters under the Securities Act of 1933, and any discounts, concessions or commissions they receive from us and any profit on the resale of securities they realize may be deemed to be underwriting compensation under applicable federal and state securities laws.

-28-

Table of Contents

The applicable prospectus supplement will, where applicable:

●

identify any such underwriter, dealer or agent;

●

describe any compensation in the form of discounts, concessions, commissions or otherwise received from us by each such underwriter or agent and in the aggregate by all underwriters and agents;

●

describe any discounts, concessions or commissions allowed by underwriters to participating dealers;

●

identify the amounts underwritten; and

●

identify the nature of the underwriter ’s or underwriters’ obligation to take the securities.

Unless otherwise specified in the related prospectus supplement, each series of securities will be a new issue with no established trading market, other than our common stock, which is listed on The NASDAQ Capital Market. We expect that any common stock sold pursuant to a prospectus supplement will be listed on The NASDAQ Capital Market, subject to official notice of issuance. We may elect to list any series of debt securities or preferred stock on an exchange, but we are not obligated to do so. It is possible that one or more underwriters may make a market in the securities, but such underwriters will not be obligated to do so and may discontinue any market making at any time without notice. No assurance can be given as to the liquidity of, or the trading market for, any offered securities.

We may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If disclosed in the applicable prospectus supplement, in connection with those derivative transactions, third parties may sell securities covered by this prospectus and such prospectus supplement, including in short sale transactions. If so, the third party may use securities pledged by us or borrowed from us or from others to settle those short sales or to close out any related open borrowings of securities, and may use securities received from us in settlement of those derivative transactions to close out any related open borrowings of securities. If the third party is or may be deemed to be an underwriter under the Securities Act of 1933, it will be identified in the applicable prospectus supplements.

Until the distribution of the securities is completed, rules of the SEC may limit the ability of any underwriters and selling group members to bid for and purchase the securities. As an exception to these rules, underwriters are permitted to engage in some transactions that stabilize the price of the securities. Such transactions consist of bids or purchases for the purpose of pegging, fixing or maintaining the price of the securities.

Underwriters may engage in overallotment. If any underwriters create a short position in the securities in an offering in which they sell more securities than are set forth on the cover page of the applicable prospectus supplement, the underwriters may reduce that short position by purchasing the securities in the open market.

The lead underwriters may also impose a penalty bid on other underwriters and selling group members participating in an offering. This means that if the lead underwriters purchase securities in the open market to reduce the underwriters ’ short position or to stabilize the price of the securities, they may reclaim the amount of any selling concession from the underwriters and selling group members who sold those securities as part of the offering.

In general, purchases of a security for the purpose of stabilization or to reduce a short position could cause the price of the security to be higher than it might be in the absence of such purchases. The imposition of a penalty bid might also have an effect on the price of a security to the extent that it were to discourage resales of the security before the distribution is completed.

We do not make any representation or prediction as to the direction or magnitude of any effect that the transactions described above might have on the price of the securities. In addition, we do not make any representation that underwriters will engage in such transactions or that such transactions, once commenced, will not be discontinued without notice.

-29-

Table of Contents

Under agreements into which we may enter, underwriters, dealers and agents who participate in the distribution of the securities may be entitled to indemnification by us against or contribution towards certain civil liabilities, including liabilities under the applicable securities laws.

If we offer securities in a subscription rights offering to our existing security holders, we may enter into a standby underwriting agreement with dealers, acting as standby underwriters. We may pay the standby underwriters a commitment fee for the securities they commit to purchase on a standby basis. If we do not enter into a standby underwriting arrangement, we may retain a dealer-manager to manage a subscription rights offering for us.

Underwriters, dealers and agents may engage in transactions with us or perform services for us in the ordinary course of business.

If indicated in the applicable prospectus supplement, we will authorize underwriters or other persons acting as our agents to solicit offers by particular institutions to purchase securities from us at the public offering price set forth in such prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on the date or dates stated in such prospectus supplement. Each delayed delivery contract will be for an amount no less than, and the aggregate amounts of securities sold under delayed delivery contracts shall be not less nor more than, the respective amounts stated in the applicable prospectus supplement. Institutions with which such contracts, when authorized, may be made include commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions and others, but will in all cases be subject to our approval.
