We are a Maritime Domain Awareness (MDA) company specializing in innovative intelligent maritime solutions. These solutions include a variety of “as a service” systems, including Data as a Service (DaaS), Robotics as a Service (RaaS), and Power as a Service (PaaS). These systems consist of a variety of platforms including the PowerBuoy®, our persistent sensor and power solution, the WAM-V® (Wave Adaptive Modular Vessel), our autonomous unmanned surface vehicle, and Merrows™, our user interface and command and control (C2) system that integrates multiple sensor feeds using software and hardware and enables artificial intelligence and machine learning (AI/ML) integration. We design, manufacture, deploy, and operate these systems for defense, security, subsea infrastructure, offshore oil and gas, offshore energy, marine research, and communication markets. We operate primarily through a combination of direct sales and leases, strategic partnerships, and long-term service agreements. Our business model emphasizes capital-light deployments, recurring revenue from service and maintenance contracts, and high-margin technology sales and leases.

We serve a global customer base, including the U.S. and allied defense agencies, offshore energy operators, and commercial interests. The common thread across these markets is the growing need for a persistent, autonomous, and sustainable offshore presence, a need we are uniquely positioned to fulfill.

We hold numerous patents and leverages decades of research including control systems, energy storage, and marine integration. Our headquarters and assembly operations are located in New Jersey, and we maintain an additional manufacturing and robotics development facility in Richmond, CA. In addition, we maintain an office at the Association for Uncrewed Vehicle Systems International (AUVSI) headquarters in Washington, D.C., which serves to strengthen our strategic position in the fast-growing uncrewed systems market.

We are committed to enabling a smarter, safer ocean economy through innovation in ocean intelligence and power. As we look forward, our strategic priorities include expanding our customer and geographic base, accelerating technology adoption, enhancing recurring revenue, and driving margin growth through platform scalability and supply chain efficiencies.

On July 22, 2026, we entered into an asset purchase agreement with Columbia Power Technologies, Inc. (the “Seller”) pursuant to which we acquired from the Seller certain of its assets. In consideration for the purchase, we issued 10,984,848 shares of our common stock to the Seller. Pursuant to registration rights that we granted under such asset purchase agreement, we filed the registration statement of which this prospectus is a part to register the resale of the 10,984,848 shares of our common stock that we issued to the Seller, though a portion of such shares are subject to restrictions on trading for a period of time after the closing of the acquisition in accordance with the terms of the asset purchase agreement. As such, the Seller is the selling stockholder under this prospectus.

Our principal executive offices are located at 28 Engelhard Drive, Monroe Township, New Jersey 08831. Our telephone number is (609) 730-0400. We were incorporated in New Jersey in 1984 and reincorporated in the State of 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.

	●	our ability to meet product enhancement, manufacturing and customer delivery deadlines and the potential impact due to disruptions to our supply chain or our ability to identify vendors that can assist with the prefabrication elements of our products, as a result of, among other things, staff shortages, order delays, and increased pricing from vendors and manufacturers;
	●	our forecasts and estimates regarding future expenses, revenue, gross margin, cash flow and capital requirements;
	●	our ability to identify and penetrate markets for our products, services, and solutions;

	●	our ability to be successful doing business internationally which requires strict compliance with applicable statutes and regulations;
	●	the current geopolitical world uncertainty, including tariffs, the conflicts between the United States, Israel and Iran, Russia’s invasion of Ukraine, the Israel/Palestine conflict, current events in Venezuela and previous attacks on merchant ships in the Red Sea;
	●	the potential impact that new foreign country tariffs may have on our ability (i) to source and procure necessary raw materials for the manufacture and provision of our products and services; and (ii) to deliver our products to such foreign countries;
	●	our ability to hire and retain key personnel, including senior management, to achieve our business objectives; and
	●	our ability to establish and maintain consistent commercial profit margins.

RISK FACTORS

An investment in our securities involves a high degree of risk. You should carefully consider the risk factors and all of the other information included in, or incorporated by reference into, this prospectus, including those risk factors included in our Annual Report on Form 10-K for the year ended April 30, 2026 and our subsequent Commission filings, in evaluating an investment in our securities. If any of these risks were to occur, our business, financial condition or results of operations could be adversely affected. In that case, the trading price of our securities could decline and you could lose all or part of your investment. When we offer and sell any securities pursuant to a prospectus supplement, we may include additional risk factors relevant to such securities in the prospectus supplement.

USE OF PROCEEDS

We will not receive any proceeds from the sale of our shares of common stock by the selling stockholders. The selling stockholders named in this prospectus will pay any underwriting fees, discounts and commissions, along with certain of the selling stockholders’ out-of-pocket expenses, incurred in connection with their sale of shares registered under this prospectus. We will bear all other costs, fees and expenses incurred by us, or by the selling stockholders, in effecting the registration, offer and sale of the shares covered by this prospectus.

DESCRIPTION OF CAPITAL STOCK

In the discussion that follows, we have summarized selected provisions of our certificate of incorporation and bylaws. You should read our certificate of incorporation and bylaws as currently in effect for more details regarding the provisions we describe below and for other provisions that may be important to you. We have filed copies of those documents with the SEC, and they are incorporated by reference herein. Please read “Where You Can Find More Information.”

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 forms a part.

Our authorized capital stock consists of 200,000,000 shares of common stock, par value $0.001 per share, and 5,000,000 shares of preferred stock, par value $0.001 per share, 700,000 of which are designated as Series A Participating Preferred Stock which may be issued upon the exercise of the preferred stock purchase rights described below under “Section 382 Tax Benefits Preservation Plan”. As discussed below, we issued on July 11, 2023 preferred stock purchase rights which are attached to our common stock in connection with our adoption of an Amended and Restated Section 382 Tax Benefits Preservation Plan as described under Section 382 Tax Benefits Preservation Plan.

As of August 20, 2026, there were 270,138,823 shares of common stock outstanding, and no shares of preferred stock were issued or outstanding. As of August 20, 2026, there also were outstanding (i) options representing the right to purchase a total of 388,715 shares of common stock at a weighted average exercise price of approximately $1.78 per share, (ii) unvested restricted and performance stock units representing the right to acquire a total of 23,830,189 shares of common stock, and (iii) 25,000,000 shares of common stock issuable upon exercise of certain outstanding warrants.

Description of 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 of Directors approved 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.

Our Board of Directors 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 of Directors 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, as well as having met certain other requirements specified in the bylaws. 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.

Amended and Restated Section 382 Tax Benefits Preservation Plan

Our Board of Directors has approved the adoption of a tax benefits preservation plan in the form of an Amended and Restated Section 382 Rights Agreement designed to protect and preserve our tax assets primarily associated with net operating loss carryforwards (“NOLs”) that could potentially be utilized in certain circumstances to offset our future taxable income and reduce its federal income tax liability. The tax benefits preservation plan was amended and restated on June 29, 2026 to among other things extend the life of the plan through June 29, 2029.

Section 382 of the Internal Revenue Code imposes limitations on the future use of a company’s NOLs if it undergoes an “ownership change.” Our ability to benefit from its tax assets would be substantially limited by Section 382 if an “ownership change” occurred. A company experiences an “ownership change” for tax purposes if the percentage of stock owned by one or a group of its 5% stockholders (as defined for tax purposes) increases by more than 50 percentage points over a rolling three-year period over the lowest percentage of stock of such corporation owned by such stockholders at any time during that period.

Our tax benefits preservation plan is similar to those adopted by numerous other public companies with significant NOLs. In order to protect our NOLs from being limited or permanently lost under Section 382, the tax benefits preservation plan is intended to reduce the likelihood of an unintended “ownership change” occurring through the buying and selling of our common stock. This is accomplished by deterring any person or group from acquiring beneficial ownership of 4.99% or more of our outstanding common stock without the approval of the Board. Our tax benefits preservation plan does not, however, block anyone from buying or selling our common stock. Accordingly, there can be no assurance that the tax benefits preservation plan will prevent an “ownership change.”

Under the terms of the tax benefits preservation plan, we distributed to our stockholders one preferred stock purchase right for each share of our common stock held as of the close of business on July 11, 2023. Any shares of common stock issued after the July 11, 2023 record date will be issued together with associated preferred stock purchase rights.

Under the tax benefits preservation plan, the rights will initially trade with our common stock. The rights will generally become exercisable only if a person (or any persons acting as a group) acquires beneficial ownership of 4.99% or more of our outstanding common stock, without the approval of the Board, after the first public announcement by us of the adoption of the tax benefits preservation plan. A person or group who acquires, without the approval of the Board, beneficial ownership of 4.99% or more of our outstanding common stock could be subject to significant dilution. If the preferred stock purchase rights become exercisable, all holders of rights, other than the person or group triggering the rights, will be entitled to purchase our common stock at a 50% discount. The Board also has the option to cause the exchange of one share of common stock for each preferred stock purchase right held. Preferred stock purchase rights held by the person or group triggering the rights will become null and void and will not be exercisable or transferable.

Stockholders who beneficially owned 4.99% or more of our outstanding common stock prior to the first public announcement by us of the adoption of the tax benefits preservation plan will not trigger any penalties under the tax benefits preservation plan so long as they do not acquire beneficial ownership of any additional shares of common stock (other than pursuant to a stock split, stock dividend, reclassification, or similar transaction effected by us) at a time when they still beneficially own 4.99% or more of such common stock. The Board also has the discretion to exempt any acquisition of our common stock from the provisions of the tax benefits preservation plan.

As amended and restated, the preferred stock purchase rights and the tax benefits preservation plan will expire no later than June 29, 2029. The preferred stock purchase rights and the tax benefits preservation plan may also expire on an earlier date upon the occurrence of other events, including a determination by our Board that (i) the tax benefits preservation plan is no longer necessary for the preservation of our tax attributes, (ii) no tax attributes may be carried forward (with such expiration occurring as of the beginning of the applicable taxable year), or (iii) prior to the time any person or group acquires 4.99% or more of our common stock, that the tax benefits preservation plan and the preferred stock purchase rights are no longer in the best interests of us and our stockholders. The preferred stock purchase rights may also be redeemed, exchanged, or terminated prior to their expiration.

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

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 NYSE American.

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 NYSE American. 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 NYSE American under the symbol “OPTT.”

SELLING STOCKHOLDERS

The following table sets forth information relating to the selling stockholders’ beneficial ownership of our shares as of August 20, 2026. This prospectus covers the offering for resale from time to time of up to 10,984,848 shares issued as part of the acquisition of the assets of Columbia Power Technologies, Inc. in June 2026.

As used in this prospectus, “selling stockholders” includes partners, pledgees, donees (including charitable organizations), assignees, transferees or other successors-in-interest selling shares received from a named selling stockholder after the date of this prospectus.

No offer or sale under this prospectus may be made by a stockholder unless that holder is listed in the table below, in a supplement to this prospectus or in an amendment to the related registration statement that has become effective under the Securities Act. We will supplement or amend this prospectus to include additional selling stockholders upon request and upon provision of all required information to us.

The following table and related footnotes set forth:

	●	the name of each selling stockholder;

	●	if different, the name of the natural person(s) who exercise(s) sole/shared voting and/or investment power with respect to the shares;

	●	the number of our shares beneficially owned by such stockholder prior to the offering;

	●	the number being offered for the stockholder’s account; and

	●	the number to be owned by such stockholder after completion of the offering (assuming the sale of all shares offered by this prospectus).

Unless otherwise indicated, none of the selling stockholders is a broker-dealer registered under Section 15 of the Exchange Act, or an affiliate of a broker-dealer registered under Section 15 of the Exchange Act.

We prepared the table based on information supplied to us by the selling stockholder. We have not sought to verify such information. The percentages of shares beneficially owned and being offered are based on the 270,138,823 shares of common stock that were outstanding as of August 20, 2026, unless otherwise stated in the footnotes to the table below. Other information about the selling stockholders may also change over time. The address of the selling stockholder is Columbia Power Acquisition, Inc., 2150 Wise Street #5702, Charlottesville, VA 22905.

PLAN OF DISTRIBUTION

The selling stockholder of the securities and any of its pledgees, assignees and successors-in-interest may, from time to time, sell any or all of their securities covered hereby on the principal trading market for such securities or any other stock exchange, market or trading facility on which the securities are traded or in private transactions. These sales may be at fixed or negotiated prices. The selling stockholder may use any one or more of the following methods when selling securities:

● ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

● block trades in which the broker-dealer will attempt to sell the securities as agent but may position and resell a portion of the block as principal to facilitate the transaction;

● purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

● an exchange distribution in accordance with the rules of the applicable exchange;

● privately negotiated transactions;

● settlement of short sales;

● in transactions through broker-dealers that agree with the selling stockholders to sell a specified number of such securities at a stipulated price per security;

● through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

● a combination of any such methods of sale; or

● any other method permitted pursuant to applicable law.

The selling stockholder may also sell securities under Rule 144 or any other exemption from registration under the Securities Act, if available, rather than under this prospectus.

Broker-dealers engaged by the selling stockholder may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the selling stockholder (or, if any broker-dealer acts as agent for the purchaser of securities, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with FINRA Rule 2440; and in the case of a principal transaction a markup or markdown in compliance with FINRA IM-2440.

In connection with the sale of the securities or interests therein, the selling stockholder may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the securities in the course of hedging the positions they assume. The selling stockholder may also sell securities short and deliver these securities to close out their short positions, or loan or pledge the securities to broker-dealers that in turn may sell these securities. The selling stockholder may also enter into option or other transactions with broker-dealers or other financial institutions or create one or more derivative securities which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The selling stockholder and any broker-dealers or agents that are involved in selling the securities may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the securities purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. The selling stockholder has informed us that it does not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the securities.

We are required to pay certain fees and expenses incurred by us incident to the registration of the securities. We have agreed to indemnify the selling stockholder against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.

We agreed to keep this prospectus effective until the earlier of (i) the date on which the securities may be resold by the selling stockholder without registration and without regard to any volume or manner-of-sale limitations by reason of Rule 144, without the requirement for us to be in compliance with the current public information under Rule 144 under the Securities Act or any other rule of similar effect or (ii) all of the securities have been sold pursuant to this prospectus or Rule 144 under the Securities Act or any other rule of similar effect. The resale securities will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the resale securities covered hereby may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the resale securities may not simultaneously engage in market making activities with respect to the common stock for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the selling stockholder will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of the common stock by the selling stockholder or any other person. We will make copies of this prospectus available to the selling stockholder and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).

Notwithstanding anything to the contrary in this plan of distribution, selling stockholders who are also our employees remain subject to the terms, conditions and restrictions of our corporate policies and procedures, including without limitation, our insider trading policy.

LEGAL MATTERS

Certain legal matters in connection with the securities offered hereby will be passed on for us by Porter Hedges LLP, Houston, Texas. Any underwriters will be advised about other issues relating to any offering by their own legal counsel.

Item 15. Indemnification of Directors and Officers.

Section 102 of the General Corporation Law of the State of Delaware permits a corporation to eliminate the personal liability of directors of a corporation to the corporation or its stockholders for monetary damages for a breach of fiduciary duty as a director, except where the director breached his duty of loyalty, failed to act in good faith, engaged in intentional misconduct or knowingly violated a law, authorized the payment of a dividend or approved a stock repurchase in violation of Delaware corporate law or obtained an improper personal benefit. The registrant’s certificate of incorporation provides that no director of the registrant shall be personally liable to it or its stockholders for monetary damages for any breach of fiduciary duty as director, notwithstanding any provision of law imposing such liability, except to the extent that the General Corporation Law of the State of Delaware prohibits the elimination or limitation of liability of directors for breaches of fiduciary duty.

Section 145 of the General Corporation Law of the State of Delaware provides that a corporation has the power to indemnify a director, officer, employee, or agent of the corporation and certain other persons serving at the request of the corporation in related capacities against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlements actually and reasonably incurred by the person in connection with an action, suit or proceeding to which he is or is threatened to be made a party by reason of such position, if such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and, in any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful, except that, in the case of actions brought by or in the right of the corporation, no indemnification shall be made with respect to any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or other adjudicating court determines that, despite the adjudication of liability but in view of all of the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

The registrant’s certificate of incorporation provides that the registrant will indemnify each person who was or is a party or threatened to be made a party to any threatened, pending or completed action, suit or proceeding (other than an action by or in the right of the registrant) by reason of the fact that he or she is or was, or has agreed to become, a director or officer of the registrant, or is or was serving, or has agreed to serve, at the registrant’s request as a director, officer, partner, employee or trustee of, or in a similar capacity with, another corporation, partnership, joint venture, trust or other enterprise (all such persons being referred to as an “Indemnitee”), or by reason of any action alleged to have been taken or omitted in such capacity, against all expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred in connection with such action, suit or proceeding and any appeal therefrom, if such Indemnitee acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the registrant’s best interests, and, with respect to any criminal action or proceeding, he or she had no reasonable cause to believe his or her conduct was unlawful.

The registrant’s certificate of incorporation provides that the registrant will indemnify any Indemnitee who was or is a party to an action or suit by or in the right of the registrant to procure a judgment in the registrant’s favor by reason of the fact that the Indemnitee is or was, or has agreed to become, a director or officer of the registrant, or is or was serving, or has agreed to serve, at the registrant’s request as a director, officer, partner, employee or trustee or, or in a similar capacity with, another corporation, partnership, joint venture, trust or other enterprise, or by reason of any action alleged to have been taken or omitted in such capacity, against all expenses (including attorneys’ fees) and, to the extent permitted by law, amounts paid in settlement actually and reasonably incurred in connection with such action, suit or proceeding, and any appeal therefrom, if the Indemnitee acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the registrant, except that no indemnification shall be made with respect to any claim, issue or matter as to which such person shall have been adjudged to be liable to the registrant, unless a court determines that, despite such adjudication but in view of all of the circumstances, he or she is entitled to indemnification of such expenses. Notwithstanding the foregoing, to the extent that any Indemnitee has been successful, on the merits or otherwise, he or she will be indemnified by the registrant against all expenses (including attorneys’ fees) actually and reasonably incurred in connection therewith. Expenses must be advanced to an Indemnitee under certain circumstances.

The registrant maintains a general liability insurance policy that covers certain liabilities of the registrant’s directors and officers arising out of claims based on acts or omissions in their capacities as directors or officers.

The registrant’s directors and officers are covered by insurance policies indemnifying them against certain liabilities, including certain liabilities arising under the Securities Act of 1933, as amended, which might be incurred by them in such capacities and against which they cannot be indemnified by the registrant.

Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement;

3) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) of this section do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

ii. That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

iii. To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

iv. That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser, if the registrant is subject to Rule 430C, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

v. That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities:

II-5

The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

1) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

2) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

3) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

4) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

b. The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

c. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
