ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement on Form S-3 that we filed with the U.S. Securities and Exchange Commission (“SEC”), using a “shelf” registration process. Under this shelf registration statement, we may offer and sell from time to time, separately or together, any combination of our common stock, preferred stock, debt securities, depositary shares, warrants, purchase contracts, purchase units, subscription rights and units in one or more offerings at an aggregate offering price of up to $300,000,000. The preferred stock, debt securities, warrants, purchase contracts, purchase units, subscription rights and units may be convertible into, or exercisable or exchangeable for, our common or preferred stock or other securities issued by us, or debt or equity securities issued by one or more other entities.

This prospectus provides you with a general description of the securities we may offer. Each time we offer and sell securities, we will provide a prospectus supplement that will contain specific information about the terms of that offering.

FORWARD-LOOKING STATEMENTS

Certain statements included or incorporated by reference in this prospectus and each prospectus supplement may not be based on historical facts and are “forward-looking statements” within the meaning of Section 27A of the Securities Act, and Section 21E of the Exchange Act. These forward-looking statements reflect our current views with respect to, among other things, future events and our financial performance. Any statements about our management’s expectations, beliefs, plans, predictions, forecasts, objectives, assumptions or future events or performance are not historical facts and may be forward-looking.

All forward-looking statements, expressed or implied, included herewith are expressly qualified in their entirety by the cautionary statements contained or referred to herein. The inclusion of forward-looking information in this prospectus and each prospectus supplement, and the documents incorporated by reference herein and therein, should not be regarded as a representation by us or any other person that the future plans, estimates or expectations contemplated by us will be achieved. We have based these forward-looking statements largely on our current expectations and projections about future events and financial trends that we believe may affect our financial condition, results of operations, business strategy and financial needs. We caution that the forward-looking statements are based largely on our expectations and are subject to a number of known and unknown risks and uncertainties that are subject to change based on factors which are, in many instances, beyond our control. Factors that may affect our results are disclosed in “Risk Factors” beginning on page 2 of this prospectus, and in the documents incorporated by reference into this prospectus and included or incorporated by reference into, and in the section titled “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2024. Some of the risks and uncertainties that may cause our actual results, performance or achievements to differ materially from those expressed include, but are not limited to, the following:

risks related to the concentration of our business in California, and specifically within Northern California, including risks associated with any downturn in the real estate sector;

changes in market interest rates that affect the pricing of our loans and deposits, our net interest income, and our borrowers’ ability to repay loans;

changes in the U.S. economy, including an economic slowdown, recession, inflation, deflation, tariffs, housing prices, employment levels, rate of growth, and general business conditions;

uncertain market conditions and economic trends nationally, regionally, and particularly in Northern California and California;

the soundness of other financial institutions and the impacts related to or resulting from bank failures and other economic and industry volatility, including increased regulatory requirements and costs and potential impacts to macroeconomic conditions;

the impact of recent and future legislative and regulatory changes, including changes in banking, securities, and tax laws and regulations and their application by our regulators;

the effects of increased competition from a wide variety of local, regional, national, and other providers of financial and investment services;

the risks associated with our loan portfolios, and specifically with our commercial real estate loans;

our ability to maintain adequate liquidity and to maintain capital necessary to fund our growth strategy and operations and to satisfy minimum regulatory capital levels;

risks related to our strategic focus on lending to small to medium-sized businesses;

the sufficiency of the assumptions and estimates we make in establishing reserves for potential loan losses and the value of loan collateral and securities;

our level of nonperforming assets and the costs associated with resolving problem loans, if any;

our ability to comply with various governmental and regulatory requirements applicable to financial institutions, including supervisory actions by federal and state banking agencies;

governmental monetary and fiscal policies, including the policies of the Federal Reserve;

risks associated with unauthorized access, cybersecurity breaches, cyber-crime, and other threats to data security;

our ability to implement, maintain, and improve effective risk management framework, disclosure controls and procedures, and internal controls over financial reporting;

our ability to adopt and successfully integrate new initiatives or technologies into our business in a strategic manner;

our ability to attract and retain executive officers and key employees and their customer and community relationships;

the impact of any future U.S. federal government shutdown and uncertainty regarding the U.S. federal government’s debt limit and credit rating;

the occurrence or impact of climate change or natural or man-made disasters or calamities, such as wildfires, droughts, mudslides, floods, and earthquakes, and particularly in California, and specifically Northern California;

changes in and impact of local, regional, and global business, economic, and political conditions and geopolitical events, such as pandemics, civil unrest, wars, and acts of terrorism; and

other factors that are discussed in the sections entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Risk Factors” on our Annual Report on Form 10-K for the year ended December 31, 2024 and our Quarterly Report on Form 10-Q for the quarter ended September 30, 2025.

The foregoing factors should not be construed as exhaustive and should be read together with the other cautionary statements included or incorporated by reference in this prospectus. If one or more events related to these or other risks or uncertainties materialize, or if our underlying assumptions prove to be incorrect, actual results may differ materially from what we anticipate. You are cautioned not to place undue reliance on forward-looking statements. Further, any forward-looking statement speaks only as of the date on which it is made and we undertake no obligation to update or revise any forward-looking statement to reflect events or circumstances after the date on which the statement is made or to reflect the occurrence of unanticipated events, except as required by law.

RISK FACTORS

Investing in securities issued by us involves certain risks. Before you invest in any securities issued by us, in addition to the other information included in, or incorporated by reference into, this prospectus, as well as the information contained in any applicable prospectus supplement, you should carefully consider the risk factors contained in the section titled “Item 1A. Risk Factors” and elsewhere in our Annual Report on Form 10-K for the year ended December 31, 2024, which is incorporated by reference into this prospectus, as updated by our Annual or Quarterly Reports for subsequent fiscal years or fiscal quarters that we file with the SEC and that are so incorporated. See “Where You Can Find More Information” for information about how to obtain a copy of these documents. You should also carefully consider the risks and other information that may be contained in, or incorporated by reference into, any prospectus supplement relating to specific offerings of securities. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also materially and adversely affect our business and operations.

USE OF PROCEEDS

We intend to use the net proceeds from the sales of the securities in the manner and for the purposes that will be set forth in the applicable prospectus supplement, which may include general corporate purposes.

DESCRIPTION OF SECURITIES WE MAY OFFER

This prospectus contains summary descriptions of our capital stock. These summary descriptions are not meant to be complete descriptions of each security. The applicable prospectus supplement for an offering may add, update or change the terms and conditions of the securities as described in this prospectus. The following description of our capital stock does not purport to be complete and is subject to, and qualified in its entirety by, our Amended and Restated Articles of Incorporation (the “articles”) and Second Amended and Restated Bylaws (the “bylaws”), each of which is incorporated by reference as an exhibit to the registration statement of which this prospectus forms a part, and to applicable California law, including the General Corporation Law of California (the “CGCL”). We urge you to read these documents for a more complete understanding of shareholder rights.

DESCRIPTION OF COMMON STOCK

We may issue, separately or together with, or upon conversion, exercise or exchange of other securities, shares of our common stock as set forth in the applicable prospectus supplement. The following section describes the material features and rights of our common stock, no par value per share. This summary does not purport to be exhaustive and is qualified in its entirety by reference to our articles and bylaws, each of which is incorporated by reference as an exhibit to the registration statement of which this prospectus forms a part, and to applicable provisions of California and federal law and regulations for additional information.

General

Our authorized capital stock consists of 100,000,000 shares of common stock with no par or stated value, and 10,000,000 shares of undesignated preferred stock, the terms of which may be established by board of directors by resolution. As of January 30, 2026, 21,376,153 shares of our common stock were outstanding, and no shares of preferred stock were designated or outstanding.

As of September 30, 2025, an aggregate of 1,361,866 shares of common stock are reserved for issuance under the Company’s 2021 Equity Incentive Plan.

All of our outstanding shares of common stock are fully paid and nonassessable.

Each share of our common stock has the same relative rights as, and is identical in all respects with, each other share of our common stock.

Voting Rights; Majority Written Consent

Holders of our common stock are entitled to one vote per share on all matters requiring shareholder action, including the election of directors. Our bylaws provide that a majority of the shares entitled to vote at a shareholders’ meeting, represented in person or by proxy, shall constitute a quorum. When a quorum is present, the affirmative vote of a majority of the shares represented at the meeting and entitled to vote, such affirmatively voting shares constituting at least a majority of the required quorum, are required to take action, unless otherwise specified by law or our articles and except for the election of directors, which are determined by a majority vote. There are no cumulative voting rights.

Any action that, under any provision of the CGCL, may be taken at a meeting of the shareholders, may be taken without a meeting and without prior notice if a consent in writing, setting forth the action so taken, shall be signed by the holders of the outstanding shares having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares are entitled to vote thereon were present and voted; provided, that unless the consents of all shareholders entitled to vote have been solicited in writing, notice of any shareholder approval without a meeting by less than unanimous consent must be given as required under the CGCL, to such shareholders who are required to receive such notice under the CGCL; and provided, further, that directors may be elected by written consent only if signed by the holders of all outstanding shares entitled to vote for the election of directors, except that action taken by shareholders to fill one or more vacancies on the board of directors (other than any vacancy created by removal) that has not been filled by the board of directors may be taken by written consent of a majority of the outstanding shares entitled to vote.

Liquidation Rights

In the event of the liquidation, dissolution or winding up of the Company, subject to the rights of the holders of any then outstanding shares of preferred stock, the holders of our common stock are entitled to receive all of our assets remaining after satisfaction of all our liabilities and the payment of any liquidation preference of any outstanding preferred stock. There are no redemption or sinking fund provisions applicable to our common stock.

Dividends

The payment of dividends is subject to the restrictions set forth in the CGCL. The CGCL provides that neither a company nor any of its subsidiaries shall make any distribution to its shareholders unless: (i) the amount of retained earnings of the company immediately prior to the distribution equals or exceeds the sum of (a) the amount of the proposed distribution plus (b) the preferential dividends arrears amount (as calculated pursuant to Section 500(b) of the CGCL), or (ii) following the distribution, the value of the company’s assets would equal or exceed the sum of its total liabilities plus the preferential rights amount (as calculated pursuant to Section 500(b) of the CGCL).

Holders of our common stock may receive dividends when, as and if declared by our board of directors out of funds legally available for the payment of dividends, subject to any restrictions imposed by regulatory authorities and the payment of any preferential amounts to which any class of preferred stock may be entitled. Our future dividend policy is subject to the discretion of our board of directors and will depend upon a number of factors, including future earnings, financial condition, liquidity, and general business conditions. Our ability to pay dividends is subject to statutory and regulatory limitations applicable to us and the Bank.

Restrictions on Ownership of Company Common Stock

The ability of a third party to acquire our stock is also limited under applicable U.S. banking laws, and regulatory approval for the acquisition of our stock may be required under certain circumstances. The Bank Holding Company Act of 1956, as amended (the “BHC Act”) requires any bank holding company to obtain the approval of the Federal Reserve prior to acquiring more than 5% of our outstanding common stock. Any corporation or other company that becomes a holder of 25% or more of our outstanding common stock, or otherwise is deemed to control us under the BHC Act, would be subject to regulation as a bank holding company under the BHC Act. In addition, any person other than a bank holding company may be required to obtain prior approval of the Federal Reserve to acquire 10% or more of our outstanding common stock under the Change in Bank Control Act (the “CBCA”). See the section entitled “Supervision and Regulation—Supervision and Regulation of the Company—Federal Oversight Over Mergers and Acquisitions, Investments and Activities” in our Annual Report on Form 10-K for the year ended December 31, 2024 for additional description of these federal law restrictions on ownership of our common stock. Further, prior approval of the California Commissioner of Financial Protection and Innovation is required for any person to acquire control of us, and control for these purposes is presumed to exist when a person owns 10% or more of our outstanding common stock.

Advance Notice Provisions for Shareholder Nominations and Shareholder Proposals

Our bylaws provide that shareholders must provide advance notice of any proposal or nomination for election as a director which a shareholder desires to bring before a meeting of shareholders. Such requirements are in addition to any requirements under SEC Rule 14a-8 or Rule 14a-19, as applicable, for shareholder proposals or director nominations sought to be included in the Company’s proxy materials.

Preferred Stock

Our articles authorize the issuance of up to 10,000,000 shares of preferred stock with such designations, powers, preferences and rights as our board of directors may from time to time determine.

The existence of shares of authorized undesignated preferred stock enables us to meet possible contingencies or opportunities in which the issuance of shares of preferred stock may be advisable, such as in the case of acquisition or financing transactions. Having shares of preferred stock available for issuance gives us flexibility in that it would allow us to avoid the expense and delay of calling a meeting of shareholders at the time the contingency or opportunity arises. Any issuance of preferred stock with voting rights or which is convertible into voting shares could adversely affect the voting power of the holders of common stock. Furthermore, the issuance of preferred stock could adversely affect the likelihood that such holders will receive dividend payments and payments upon liquidation. The shares of preferred stock that may be issued in the future may have other rights, including economic rights senior to our common stock, and, as a result, could have an adverse effect on the market value of our common stock.

Any of these actions could have an anti-takeover effect and discourage a transaction that some or a majority of our shareholders might believe to be in their best interests or in which our shareholders might receive a premium for their shares over our then-market price.

Anti-Takeover Provisions

Provisions of our articles and bylaws, and the CGCL and federal banking regulations applicable to us, may be deemed to have anti-takeover effects and may delay, defer or prevent a change of control of the Company and/or limit the price that certain investors may be willing to pay in the future for shares of our common stock. See the sections entitled “Supervision and Regulation—Supervision and Regulation of the Company―Federal Oversight Over Mergers and Acquisitions, Investments and Activities” in our Annual Report on Form 10-K for the year ended December 31, 2024 and “Restrictions on Ownership of Company Common Stock” above for a description of the federal banking regulations applicable to us that may be deemed to have anti-takeover effects.

Authorized but Unissued Shares. The corporate laws and regulations applicable to us enable our board of directors to issue, from time to time and at its discretion, but subject to the rules of any applicable securities exchange, any authorized but unissued shares of our common or preferred stock. Any such issuance of shares could be utilized for a variety of corporate purposes, including future offerings to raise additional capital, acquisitions and employee benefit plans. The ability of our board of directors to issue authorized but unissued shares of our common or preferred stock at its sole discretion may enable our board of directors to sell shares to individuals or groups who the board of directors perceives as friendly with management, which may make more difficult unsolicited attempts to obtain control of our organization. In addition, the ability of our board of directors to issue authorized but unissued shares of our capital stock at its sole discretion could deprive the shareholders of opportunities to sell their shares of common stock or preferred stock for prices higher than prevailing market prices.

Preferred Stock. Our articles contain provisions that permit our board of directors to issue, without any further vote or action by the shareholders, shares of preferred stock in one or more series and, with respect to each such series, to fix the number of shares constituting the series and the designation of the series, the voting rights (if any) of the shares of the series, and the powers, preferences and relative, participation, optional and other special rights, if any, and any qualifications, limitations or restrictions, of the shares of such series.

Board Size and Vacancies. Our bylaws enable our board of directors to increase the size of the board of directors between annual meetings and fill the vacancies created by the increase by a majority of the remaining directors.

No Cumulative Voting. Our bylaws do not permit cumulative voting in the election of directors. In the absence of cumulative voting, the holders of a majority of the shares of our common stock may elect all of the directors standing for election, if they should so choose.

Special Meetings of Shareholders. For a special shareholders’ meeting to be called by one or more shareholder(s), our bylaws require the request of holders of at least 10% of the outstanding shares of our capital stock entitled to vote at a meeting to call a special shareholders’ meeting.

Advance Notice Procedures for Director Nominations and Shareholder Proposals. Our bylaws establish an advance notice procedure with regard to business to be brought before an annual or special meeting of shareholders and with regard to the nomination of candidates for election as directors, other than by or at the direction of the board of directors. Although this procedure does not give our board of directors any power to approve or disapprove shareholder nominations for the election of directors or proposals for action, it may have the effect of precluding a contest for the election of directors or the consideration of shareholder proposals if the established procedure is not followed, and of discouraging or deterring a third party from conducting a solicitation of proxies to elect its own slate of directors or to approve its proposal without regard to whether consideration of the nominees or proposals might be harmful or beneficial to our shareholders and us.

Amending Certain Provisions of our Articles. Our articles require a two-thirds vote of the directors then in office and two-thirds vote of our shareholders to modify the sections of our articles addressing limitation of liability and indemnification of our officers and directors, which provide limitation of liability and indemnification to the maximum extent permitted by law, and addressing the amendment of the articles.

Amending our Bylaws. Our board of directors may amend our bylaws, other than a bylaw specifying or changing a fixed number of directors or the maximum or minimum number or changing from a fixed to a variable board or vice versa, without shareholder approval.

Approval of Merger. Under the CGCL, most business combinations, including mergers, consolidations and sales of substantially all of the assets of a California corporation, must be approved by the vote of the holders of at least a majority of the outstanding shares of common stock and any other affected class of stock of such corporation. The articles of incorporation or bylaws of a California corporation may, but are not required to, set a higher standard for approval of such transactions. Our articles and bylaws do not set higher limits.

California Law and Federal Banking Laws. We are subject to the provisions of Section 1203 of the CGCL, which contains provisions that may have the effect of deterring hostile takeovers or delaying or preventing changes in control in which our shareholders could receive a premium for their shares or other changes in our management. First, if an “interested party” makes an offer to purchase the shares of some or all of our existing shareholders, we must obtain an affirmative opinion in writing as to the fairness of the offering price prior to completing the transaction. California law considers a person to be an “interested party” if the person directly or indirectly controls our company, if the person is directly or indirectly controlled by one of our officers or directors, or if the person is an entity in which one of our executive officers or directors holds a material financial interest. If, after receiving an offer from such an “interested person”, we receive a subsequent offer from a neutral third party at least 10 days prior to the date for acceptance of the tendered shares or the vote or notice of shareholder approval of the offer from such an “interested person”, then we must notify our shareholders of such third party offer and afford each of them the opportunity to withdraw their vote, consent or proxy previously given to the “interested party” offer before such vote, consent or proxy becomes effective.

We are also subject to other provisions of the CGCL, which include voting requirements that may also have the effect of deterring hostile takeovers, disposing of our assets or delaying or preventing changes in control of our management. Under Section 1101 of the CGCL, except in (i) a short-form merger or (ii) a merger of a corporation into a subsidiary in which it owns at least 90% of the outstanding shares of each class, if a single entity or constituent corporation owns more than 50% of any class of our capital stock and attempts to merge our Company into itself or other constituent corporation, the Company’s non-redeemable securities may only be exchanged for non-redeemable securities of the surviving entity, unless all of the shareholders of the applicable class of non-redeemable securities consent to the transaction or the terms of the transaction are approved and determined to be fair by the DFPI. Section 1001(d) of the CGCL provides that any proposed sale or disposition of all or substantially all of our assets to any other corporation that we are controlled by or under common control with must be consented to by our shareholders holding at least 90% of the of the voting power of our capital stock or approved and determined fair by the California Department of Financial Protection and Innovation (“DFPI”), provided, however that this restriction does not apply if the disposition is to a domestic or foreign corporation or other business entity in consideration of the nonredeemable common shares or nonredeemable equity securities of the acquiring party or its parent. Sections 1101 and 1001 of the CGCL could make it significantly more difficult for a third party to acquire control of our Company by preventing a possible acquirer from cashing out minority shareholders or selling substantially all of our assets to a related party and therefore could discourage a hostile bid, or delay, prevent or deter entirely a merger, acquisition or tender offer in which our shareholders could receive a premium for their shares, or effect a proxy contest for control of us or other changes in our management.

Furthermore, the BHC Act, CBCA, and California Financial Code impose notice, application and approvals and ongoing regulatory requirements on any shareholder or other party that seeks to acquire direct or indirect control of bank holding companies or banks, as applicable. These laws could delay or prevent an acquisition.

Limitation of Liability and Indemnification

For a description of the limitation of liability and indemnification arrangements applicable to our directors and officers, see the section entitled “Executive Compensation—Limitation of Liability and Indemnification” in the Company’s Proxy Statement for the 2025 Annual Meeting of Shareholders incorporated herein by reference.

Other Matters

Under our articles and bylaws, the holders of our common stock have no preemptive or other subscription rights and there are no redemption, sinking fund or conversion privileges applicable to our common stock.

Exclusive Forum Selection

Our bylaws provide that, subject to limited exceptions, the United States District Court for the Northern District of California (or, in the event that the United States District Court for the Northern District of California does not have jurisdiction, any other federal or state court of California) will be the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers or other employees to us or our shareholders, (iii) any action asserting a claim against us or any of our directors, officers or other employees arising pursuant to any provision of the CGCL, our articles or our bylaws or (iv) any other action asserting a claim against us or any of our directors, officers or other employees that is governed by the internal affairs doctrine. Our bylaws will further provide that, unless we consent in writing to the selection of an alternative forum, the federal district courts of the United States of America will, to the fullest extent permitted by applicable law, be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the federal securities laws, including the applicable rules and regulations promulgated thereunder. Any person purchasing or otherwise acquiring any interest in any shares of our capital stock will be deemed to have notice of and to have consented to this provision of our bylaws. Although we believe this provision benefits us by providing increased consistency in the application of California and federal securities law in the types of lawsuits to which it applies, the provision may have the effect of discouraging lawsuits against our directors and officers.

Section 27 of the Exchange Act vests exclusive federal jurisdiction for all claims brought to enforce any duty or liability created under the Exchange Act. Therefore, claims to enforce any duty or liability created under the Exchange Act must be brought in a federal court as required by Section 27 of the Exchange Act and as provided in the exclusive forum selection provision of our bylaws.

In addition, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder. As a result, there is uncertainty as to whether a court would enforce a forum selection clause in connection with claims arising under the Securities Act and the rules and regulations thereunder, and in any event, shareholders will not be deemed to have waived the Company’s compliance with the federal securities laws and the rules and regulations thereunder.

DESCRIPTION OF PREFERRED STOCK

The following section describes the general terms of preferred stock that we may issue. The specific terms of any series of preferred stock will be described in the prospectus supplement relating to that series of preferred stock. The terms of any series of preferred stock may differ from the terms described below. Certain provisions of our preferred stock described below and in any prospectus supplement are not complete. The summary does not purport to be exhaustive and is qualified in its entirety by reference to our articles and our bylaws, each of which is incorporated by reference as an exhibit to the registration statement of which this prospectus forms a part, and to applicable California law, including the CGCL.

General

Our articles authorize our board of directors to establish one or more series of preferred stock. Unless required by law or any stock exchange, up to 10,000,000 authorized but unissued shares of preferred stock will be available for issuance without further action by our shareholders. Our board of directors is authorized to divide the preferred stock into series and, with respect to each series, to fix and determine the designation, terms, preferences, limitations and relative rights thereof, including dividend rights, dividend rates, conversion rights, voting rights, redemption rights and terms, liquidation preferences, sinking fund provisions and the number of shares constituting the series. Without shareholder approval, we could issue preferred stock that could impede or discourage an acquisition attempt or other transaction that some, or a majority, of our shareholders may believe is in their best interests or in which they may receive a premium for their common stock over the market price of the common stock. While the terms of preferred stock may vary from series to series, holders of our common stock should assume that all shares of preferred stock will be senior to our common stock in respect of distributions and on liquidation.

The prospectus supplement relating to a particular series of preferred stock will contain a description of the specific terms of that series, including, as applicable:

the title, designation, number of shares and stated or liquidation value of the preferred stock;

the dividend amount or rate or method of calculation, the payment dates for dividends and the place or places where the dividends will be paid, whether dividends will be cumulative or noncumulative, and, if cumulative, the dates from which dividends will begin to accrue;

any conversion or exchange rights;

whether the preferred stock will be subject to redemption and the redemption price and other terms and conditions relative to the redemption rights;

any liquidation rights;

any sinking fund provisions;

any voting rights;

the exchange or market, if any, where the preferred stock will be listed or traded; and

any other rights, preferences, privileges, limitations and restrictions that are not inconsistent with the terms of our articles.

Upon the issuance and payment for shares of preferred stock, the shares will be fully paid and nonassessable. Except as otherwise may be specified in the prospectus supplement relating to a particular series of preferred stock, holders of preferred stock will not have any preemptive or subscription rights to acquire any class or series of our capital stock and each series of preferred stock will rank on a parity in all respects with each other series of our preferred stock and prior to our common stock as to dividends and any distribution of our assets.

As stated above in the “Description of Our Common Stock”, the authorization of the preferred stock could have the effect of making it more difficult or time consuming for a third party to acquire a majority of our outstanding voting stock or otherwise effect a change of control. Shares of the preferred stock may also be sold to third parties that indicate that they would support the board of directors in opposing a hostile takeover bid. The availability of the preferred stock could have the effect of delaying a change of control and of increasing the consideration ultimately paid to our shareholders. The board of directors may authorize the issuance of preferred stock for capital-raising activities, acquisitions, joint ventures or other corporate purposes that have the effect of making an acquisition of the Company more difficult or costly, as could also be the case if the board of directors were to issue additional common stock for such purposes. See “Anti-Takeover Provisions.”

Redemption

If so specified in the applicable prospectus supplement, a series of preferred stock may be redeemable at any time, in whole or in part, at our option, and may be mandatorily redeemable or convertible. Restrictions, if any, on the repurchase or redemption by us of any series of our preferred stock will be described in the applicable prospectus supplement relating to that series. Generally, any redemption of our preferred stock will be subject to prior Federal Reserve approval. Any partial redemption of a series of preferred stock would be made in the manner described in the applicable prospectus supplement relating to that series.

Upon the redemption date of shares of preferred stock called for redemption or upon our earlier call and deposit of the redemption price, all rights of holders of the preferred stock called for redemption will terminate, except for the right to receive the redemption price.

Dividends

Holders of each series of preferred stock will be entitled to receive cash dividends only when, as and if declared by our board of directors out of funds legally available for dividends on such preferred stock. The rates or amounts and dates of payment of dividends will be described in the applicable prospectus supplement relating to each series of preferred stock. Dividends will be payable to holders of record of preferred stock on the record dates fixed by our board of directors. Dividends on any series of preferred stock may be cumulative or noncumulative, as described in the applicable prospectus supplement.

Our board of directors may not declare, pay or set apart funds for payment of dividends on a particular series of preferred stock unless full dividends on any other series of preferred stock that ranks equally with or senior to such series of preferred stock with respect to the payments of dividends have been paid or sufficient funds have been set apart for payment for either of:

all prior dividend periods of each such series of preferred stock that pay dividends on a cumulative basis; or

the immediately preceding dividend period of each such series of preferred stock that pays dividends on a noncumulative basis.

Partial dividends declared on shares of any series of preferred stock and other series of preferred stock ranking on an equal basis as to dividends will be declared pro rata. A pro rata declaration means that the ratio of dividends declared per share to accrued dividends per share will be the same for all series of preferred stock of equal priority.

Liquidation Preference

In the event of the liquidation, dissolution or winding-up of us, holders of each series of preferred stock will have the right to receive distributions upon liquidation in the amount described in the applicable prospectus supplement relating to each series of preferred stock, plus an amount equal to any accrued but unpaid dividends. These distributions will be made before any distribution is made on our common stock or on any securities ranking junior to such preferred stock upon liquidation, dissolution or winding-up.

However, holders of the shares of preferred stock will not be entitled to receive the liquidation price of their shares until we have paid or set aside an amount sufficient to pay in full the liquidation preference of any class or series of our capital stock ranking senior as to rights upon liquidation, dissolution or winding up. Unless otherwise provided in the applicable prospectus supplement, neither a consolidation or merger of the Company with or into another corporation nor a merger of another corporation with or into the Company nor a sale or transfer of all or part of the Company’s assets for cash or securities will be considered a liquidation, dissolution or winding up of the Company.

If the liquidation amounts payable to holders of preferred stock of all series ranking on a parity regarding liquidation are not paid in full, the holders of the preferred stock of these series will have the right to a ratable portion of our available assets up to the full liquidation preference. Holders of these series of preferred stock or such other securities will not be entitled to any other amounts from us after they have received their full liquidation preference.

Conversion and Exchange

The prospectus supplement will indicate whether and on what terms the shares of any future series of preferred stock will be convertible into or exchangeable for shares of any other class, series or security of the Company or any other corporation or any other property (including whether the conversion or exchange is mandatory, at the option of the holder or our option, the period during which conversion or exchange may occur, the initial conversion or exchange price or rate and the circumstances or manner in which the amount of common or preferred stock or other securities issuable upon conversion or exchange may be adjusted). It will also indicate for preferred stock convertible into common stock, the number of shares of common stock to be reserved in connection with, and issued upon conversion of, the preferred stock (including whether the conversion or exchange is mandatory, the initial conversion or exchange price or rate and the circumstances or manner in which the amount of common stock issuable upon conversion or exchange may be adjusted) at the option of the holder or our option and the period during which conversion or exchange may occur.

Voting Rights

The holders of shares of preferred stock will have no voting rights, except:

as otherwise stated in the applicable prospectus supplement;

as otherwise stated in the articles of amendment to our articles establishing the series of such preferred stock; and

as otherwise required by applicable law.

Transfer Agent and Registrar

The transfer agent, registrar, dividend paying agent and depositary, if any, for any preferred stock offering will be stated in the applicable prospectus supplement.

DESCRIPTION OF DEBT SECURITIES

The complete terms of the debt securities will be contained in the indenture and supplemental indenture applicable to the debt securities. These documents will be included or incorporated by reference into this prospectus or the applicable prospectus supplement. You should read the indenture and applicable supplemental indenture relating to any debt securities. You should also read the applicable prospectus supplement, which will contain additional information and which may update or change some of the information below.

We may issue, separately or together with, or upon conversion, exercise or exchange of other securities, debt securities, including debentures, notes, bonds and other evidence of indebtedness as set forth in the applicable prospectus supplement. The debt securities may be either secured or unsecured and will be either senior debt securities or subordinated debt securities. The debt securities will be issued under one or more separate indentures between us and a trustee to be specified in an accompanying prospectus supplement. Senior debt securities will be issued under a senior indenture and subordinated debt securities will be issued under a subordinated indenture. We refer to the senior indenture and the subordinated indenture together as the indentures. This prospectus, together with the applicable prospectus supplement, will describe the terms of each series of debt securities that we may offer from time to time.

The following summary of the material provisions of the indentures and the debt securities does not purport to be complete and is subject to, and is qualified in its entirety by reference to, the provisions of the applicable indenture and certificates evidencing the applicable debt securities. The specific terms of the applicable indenture and debt securities will be described in the applicable prospectus supplement. If any particular terms of the applicable indenture or debt securities described in a prospectus supplement differ from any of the terms described below, then the terms described below will be deemed to have been superseded by those described in the applicable prospectus supplement.

Capitalized terms used but not defined in this section have the meanings given to those terms in the applicable prospectus supplement or, if not defined in the applicable prospectus supplement, in the applicable indenture.

As used in this section, “we,” “our,” “us” and the “Company” refer only to Five Star Bancorp and not to its wholly owned subsidiary.

General

Debt securities may be issued in separate series without limitation as to aggregate principal amount. We may specify a maximum aggregate principal amount for the debt securities of any series. We are not limited as to the amount of debt securities that we may issue under the indentures. Unless otherwise provided in a prospectus supplement, a series of debt securities may be reopened to issue additional debt securities of such series. The subordinated debt securities will be subordinated as described below under the heading “—Subordinated Debt.”

The prospectus supplement relating to a particular series of debt securities will set forth the material terms of the debt securities being offered, as established pursuant to a board resolution, in an officer’s certificate or in a supplemental indenture, including:

the title of the debt securities and whether they are senior debt securities or subordinated debt securities;

the offering price (which may be expressed as a percentage of the aggregate principal amount) of the debt securities;

the aggregate principal amount of such series that may be authenticated and delivered under the indentures (except for securities authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other securities of the series pursuant to the indenture and except for any securities deemed never to have been authenticated and delivered);

the maturity date or dates;

if applicable, whether the debt securities shall be subject to the defeasance provisions described below under “—Satisfaction and Discharge” or such other defeasance provisions specified in the applicable prospectus supplement for the debt securities;

any conversion or exchange provisions;

the date of the debt securities if other than the date of original issuance;

the rate or rates, and if applicable the method used to determine the rate, at which the debt securities of such series will bear interest, if any, the date or dates from which such interest will accrue, the date or dates on which such interest will be payable and the record date or dates for the interest payable on any debt securities on any interest payment date;

the place or places where payments of principal and interest may be made and securities may be surrendered for registration of transfer or for exchange;

the obligation, if any, of the Company to redeem or purchase the debt securities of such series, at the option of the Company or at the option of a holder thereof, pursuant to any sinking fund or other redemption provisions and the period or periods within which, the price or prices at which and the terms and conditions upon which the debt securities of the series may be so redeemed or purchased, in whole or in part;

if issued other than in minimum denominations of $1,000 or any multiple of $1,000, or $5,000 in the case of bearer securities, the denominations in which the debt securities will be issuable;

the portion of the principal amount that will be payable upon acceleration of maturity, if other than the entire principal amount;

if other than U.S. currency, the currency, currencies or currency units in which principal, premium, if any, or interest will be payable and the manner of determining the equivalent thereof in U.S. currency;

if the principal of (and premium, if any, on) or any interest on the debt securities is to be payable, at our election or the election of a holder thereof, in one or more currencies other than that the currency or currencies in which the debt securities are stated to be payable, the currency or currencies in which payment is to be made payable and the periods and terms upon which such election is to be made;

if the amount of payments of principal of (and premium, if any, on) or any interest on the debt securities of the series may be determined by reference to an index, the manner in which such amounts shall be determined;

whether the debt securities will be issuable in book-entry only form;

any interest rate calculation agents, exchange rate calculation agents or other agents for the debt securities, if other than the trustee;

whether and under what circumstances we will pay additional amounts in respect of any series of debt securities and whether we have the option to redeem such debt securities rather than pay such additional amounts;

any provisions relating to the extension of maturity of, or the renewal of, the debt securities of such series, or the conversion of the debt securities of such series into other securities of the Company;

any provisions relating to the purchase or redemption of all or any portion of a tranche or series of debt securities, including the period of notice required to redeem those debt securities;

the terms and conditions, if any, pursuant to which the debt securities are secured;

any subordination provisions applicable to the subordinated debt securities if different from those described below under “—Subordinated Debt;”

any other terms or provisions relating to the payment of principal of, premium (if any) or interest thereon, including, but not limited to, whether such debt securities are issuable at a discount or premium, as amortizable debt securities and if payable in, convertible or exchangeable for commodities or other securities of ours; and

any other specific terms of such debt securities.

If we denominate the purchase price of any of the debt securities in a foreign currency or currencies, or if the principal of or premium, if any, or interest on any series of debt securities is payable in a foreign currency or currencies, we will include in the applicable prospectus supplement information on the restrictions, elections, material United States federal income tax considerations, specific terms and other information with respect to that issue of debt securities and the relevant foreign currency or currencies.

Unless otherwise specified in the prospectus supplement, the debt securities will be registered debt securities. Debt securities may be sold at a substantial discount below their stated principal amount, bearing no interest or interest at a rate which at the time of issuance is below market rates. The material United States federal income tax considerations applicable to debt securities sold at a discount will be described in the applicable prospectus supplement.

Senior Debt

Except as otherwise provided in a prospectus supplement, senior debt securities will be unsecured and will rank equally with all other unsecured and unsubordinated debt of the Company, and will rank senior in right of payment to any subordinated debt.

Subordinated Debt

Except as otherwise provided in a prospectus supplement, subordinated debt securities will be unsecured and will be subordinated in right of payment to the prior payment in full of all of our Senior Indebtedness, as more fully described in the applicable prospectus supplement. Notwithstanding the foregoing, if a deposit is made in accordance with the terms of the indenture with respect to any debt securities (and provided all other conditions set out in the indenture shall have been satisfied with respect to such debt securities), then, when the 90^th day after such deposit has ended, no money obligations so deposited, and no proceeds thereon, will be subject to any rights of holders of Senior Indebtedness, including any rights of subordination.

Under the subordinated debt indenture, Senior Indebtedness means, without duplication, the principal, premium, if any, unpaid interest (including interest accruing on or after the filing of any petition in bankruptcy or for reorganization, whether or not a claim for post-filing interest is allowed in such proceeding), fees, charges, expenses, reimbursement and indemnification obligations, and all other amounts payable under or in respect of the following indebtedness, whether any such indebtedness exists as of the date of the indenture or is created, incurred or assumed after such date:

all obligations for borrowed money;

all obligations evidenced by debentures, debt securities or other similar instruments;

all obligations associated with derivative products, including but not limited to, securities contracts, foreign currency exchange contracts, swap agreements (including interest rate and foreign exchange rate swap agreements), cap agreements, floor agreements, collar agreements, interest rate agreements, foreign exchange rate agreements, options, commodity futures contracts, commodity option contracts and similar financial instruments;

all obligations in respect of letters of credit or bankers acceptances or similar instruments (or reimbursement obligations with respect thereto);

all obligations to pay the deferred purchase price of property or services, except trade accounts payable arising in the ordinary course of business;

all indebtedness of others guaranteed by us or any of our subsidiaries or for which we or any of our subsidiaries is legally responsible or liable (whether by agreement to purchase indebtedness of, or to supply funds or to invest in, others);

indebtedness secured by any mortgage, pledge, lien, charge, encumbrance or any security interest existing on property owned by the Company but excluding any obligations of the Company which are required (as opposed to elected) to be treated as finance leases under generally accepted accounting principles;

purchase money and similar obligations; and

any renewals, extensions, refundings or replacements of any of the foregoing.

Methods of Receiving Payments on the Debt Securities

Unless otherwise indicated in a prospectus supplement, the debt securities will be payable as to principal, redemption premium, if any, and interest at the office or agency of the paying agent (which may be us) or, at our option, payment of interest may be made by check mailed to the holders of the debt securities at their last addresses as they appear on the register of holders or wired if held in book-entry form.

Events of Default; Waiver

Unless we indicate otherwise in a prospectus supplement with respect to a particular series of debt securities, an “event of default,” when used in the indentures, means any of the following:

our default in the payment of the principal (or premium, if any) on any of the debt securities of such series as and when due, either at maturity, upon redemption, by declaration or otherwise, or any payment required by any sinking or analogous fund with respect to any series of the debt securities;

our default in the payment of any installment of interest on the debt securities when due, and continuance of such default for a period of 90 days;

our failure to observe or perform any other covenant or agreement in the debt securities or the applicable indenture and the continuance of such default or breach for a period of 90 days after our receipt of written notice from the trustee or the holders of at least 25% in aggregate principal amount of the debt securities then outstanding of that series specifying such failure and requiring it to be remedied;

a court having jurisdiction enters a decree or order for relief in respect of us or a Material Subsidiary in an involuntary case or proceeding under any applicable bankruptcy, insolvency or other similar law, or appointing a receiver, liquidator, assignee, custodian, trustee, sequestrator (or similar official) of us or a Material Subsidiary or for any substantial part of our or its respective property, or ordering the winding-up or liquidation of our affairs shall have been entered and remained unstayed and in effect for a period of 60 consecutive days;

we or a Material Subsidiary commence a voluntary case or proceeding under any applicable bankruptcy, insolvency or other similar law, or consent to the entry of a decree or order for relief in an involuntary case or proceeding under any such law, or the consent to the appointment of or taking possession by a receiver, liquidator, assignee, trustee, custodian, sequestrator (or other similar official) of us or a Material Subsidiary or of any substantial part of our or its respective property, or the making by us or a Material Subsidiary of a general assignment for the benefit of creditors; or

any other event of default provided with respect to a particular series of debt securities, as described in the prospectus supplement with respect to the offering of such series.

A Material Subsidiary means Five Star Bank or any successor thereof or any of our subsidiaries that is a depository institution and that has consolidated assets equal to 80% or more of our consolidated assets.

If an event of default occurs and continues as described in the first, second, third or sixth bullet above, either the trustee or the holders of at least 25% in aggregate principal amount of the debt securities of that series then outstanding by written notice to us (with a copy to the trustee, if given by holders) may declare the principal amount of the debt securities of that series to be immediately due and immediately payable. If an event of default occurs and continues as described in the fourth or fifth bullet above, the principal amount of all of the debt securities issued under the indentures shall automatically be deemed immediately due and payable.

The indentures also provide that the holders of a majority in principal amount of the debt securities of each series outstanding at the time may, on behalf of the holders of all of the debt securities of that series, waive any past default with respect to the debt securities and its consequences, except a default in the payment of the principal of, premium, if any, and interest on the debt securities or a bankruptcy or insolvency-related default, or with respect to any covenant or provision that cannot be modified or amended under the terms of the indenture without the holder of such outstanding debt security so affected.

The holders of a majority in principal amount of the debt securities of each series may direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee. However, the trustee may refuse to follow any direction that conflicts with law or the indentures or that the trustee determines in good faith may be unjustly prejudicial to the holders of the debt securities not consenting or that may involve the trustee in personal liability. In addition, the trustee may take any other action it deems proper that is not inconsistent with any such direction received from the holders of a majority in principal amount of the debt securities.

The trustee shall be under no obligation to exercise any of the rights or powers vested in it by the indentures at the request, order or direction of any of the holders of any debt securities or related coupons pursuant to the provisions of the indentures, unless such holders shall have offered to the trustee security or indemnity reasonably satisfactory to it against the losses, costs, expenses and liabilities which might be incurred by it in compliance with such request, order or direction. Except to enforce the right to receive payment of principal, premium, if any, or interest, no holder of a debt security will have any right to institute any proceeding, judicial or otherwise, with respect to the indenture, or for the appointment of a receiver or trustee, or for any other remedy under the indenture unless:

such holder has previously given the trustee written notice of a continuing event of default;

holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series have made a written request to the trustee to institute proceedings in respect of such event of default in its own name as trustee under the indenture;

such holders provide to the trustee reasonable indemnity acceptable to the trustee against the costs, expenses and liabilities to be incurred with such request;

the trustee has failed to institute a proceeding within 60 days after its receipt of the notice, request and offer of indemnity; and

the holders of a majority in aggregate principal amount of the outstanding debt securities do not give the trustee a direction inconsistent with the request within such 60-day period.

Each indenture requires the applicable trustee to notify the holders of a series regarding the existence of any default known to the trustee, unless the default has been cured or waived. In addition, except in the case of a default in payment of principal of or interest on any debt security or the payment of any sinking or purchase fund installment, the trustee may withhold notice of a default if and so long as the trustee in good faith determines that withholding the notice is in the interests of the holders of the debt securities. Furthermore, the trustee shall not provide notice of default to the holders of debt securities following our failure to duly observe or perform any of the covenants or agreements contained in the debt securities or indenture (other than certain payment obligations) unless at least 30 days after the occurrence thereof. For purposes of these requirements, a “default” means any event which is, or after notice or lapse of time or both would become, an event of default under the indentures with respect to the debt securities of such series.

We are required to deliver to the trustee, within 120 days after the end of each fiscal year, commencing with the year during which the first series of debt securities is issued under an indenture, a written statement signed by certain officers regarding our performance under the indenture throughout the year and specifying any known default in the fulfilment of any of our obligations under the indenture, together with certain additional details regarding any such known default.

Merger, Consolidation, Sale, Lease or Conveyance

Unless otherwise indicated in a prospectus supplement with respect to a particular series of debt securities, we will not merge into or consolidate with any other corporation, or sell or convey all or substantially all of our assets to any person, firm, or corporation, unless:

either we are the continuing corporation or the successor corporation is a corporation organized and existing under the laws of the United States or a state thereof or the District of Columbia and expressly assumes the due and punctual payment of the principal, premium, if any, and interest on all the debt securities according to their tenor, and the due and punctual performance and observance of all of the covenants and conditions of the indenture to be performed by us by supplemental indenture, executed and delivered to the trustee by such successor corporation;

neither we nor such successor corporation, immediately after giving effect to such merger, consolidation, sale or conveyance, will be in default in the performance of any covenant or condition under the applicable indenture; and

we shall have delivered to the trustee an officer’s certificate and an opinion of counsel, each stating that the transaction complies with the terms of the applicable indenture and that all conditions precedent in such indenture provided for relating to such transaction have been complied with.

In the case of any such consolidation or merger, sale or conveyance and upon any such assumption by the successor corporation, the successor corporation shall succeed to, and be substituted for, us under the applicable indenture with the same effect as if it had been an original party to such indenture.

Certain Covenants

The applicable prospectus supplement will describe any restrictive covenants applicable to any debt securities we offer for sale.

Modification of the Indenture

Unless we indicate otherwise in a prospectus supplement and except as set forth below, modification and amendment of an indenture, or entry into a supplemental indenture applicable to the debt securities, may be made only when authorized by our board of directors and with the consent of the holders of not less than a majority in principal amount of the debt securities outstanding affected by such supplemental indenture, voting together as a single class.

Notwithstanding the foregoing, no modification or amendment of an indenture as applicable to any series of debt securities may:

extend the fixed maturity of any debt security, or reduce the principal amount thereof or premium, if any, or reduce the rate or extend the time of payment of interest thereon, without the consent of the holder of each debt security so affected;

reduce the percentage in principal amount of outstanding debt securities that is required for any supplemental indenture without the consent of the holders of all debt securities then outstanding;

modify the subordination provisions in a manner adverse to the holders of any debt security; or

modify any of the applicable provisions with respect to modification and waiver.

In addition, we and the trustee may modify or amend the indentures as applicable to the debt securities, with the consent of our board of directors but without the consent of any holder of the debt securities, for any of the following purposes:

to evidence the succession of another corporation to the Company, or successive successions, and provide for the successor’s assumption of our covenants, agreements and obligations under the indentures and the debt securities issued thereunder;

to add further covenants, restrictions, conditions or provisions as our board of directors considers to be for the protection of the holders of the debt securities, and to make the occurrence, or the occurrence and continuance, of a default in any of such additional covenants, restrictions, conditions or provisions an event of default permitting the enforcement of all or any of the remedies provided under the applicable indenture, with such period of grace and subject to such conditions as such supplemental indenture may provide;

to add or change any of the provisions of the indenture to provide that bearer securities may be registrable as to principal, to change or eliminate any restrictions on the payment of principal of or any premium or interest on bearer securities, to permit bearer securities to be issued in exchange for Registered Securities, to permit bearer securities to be issued in exchange for bearer securities of other authorized denominations or to permit or facilitate the issuance of debt securities in uncertificated form; provided, that any such action shall not adversely affect the interests of the holders of the debt securities or any related coupons in any material respect;

to modify, eliminate or add provisions of the indenture to such extent as necessary in order to effect the qualification of the applicable indenture under the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”), or any similar federal statute thereafter enacted, and to add such other provisions as may be expressly permitted by the Trust Indenture Act, excluding Section 316(a)(2) thereof or any corresponding provision in any similar federal statute hereafter enacted;

to modify, eliminate or add to any provisions of the indenture; provided that any such change or elimination (i) becomes effective only when there are no outstanding debt securities and created prior to the execution of such supplemental indenture that is entitled to the benefit from such provision or (ii) does not apply to any outstanding debt security;

(i) to cure any ambiguity or to correct or supplement any provision in the indenture or any supplemental indenture which may be defective or inconsistent with any other provision, (ii) to convey, transfer, assign, mortgage or pledge any property to or with the trustee or (iii) to make such other provisions in regard to matters or questions arising under the indenture; provided, that no such provision shall adversely affect in any material respect the interests of the holders of the debt securities or any related coupons, including provisions necessary or desirable to provide for or facilitate the administration of the trusts;

to secure any series of debt securities; and

to evidence and provide for the acceptance and appointment by a successor trustee with respect to the debt securities of one or more series and to add or change any provisions of the indenture as necessary to provide for or facilitate the administration of the trusts.

The trustee shall not be obligated to enter into any amendment or supplemental indenture that adversely affects the trustee’s own rights, duties or immunities under the applicable indenture or otherwise.

Subject to the requirements for the holders to waive a default related to bankruptcy events, defaults related to covenants or provisions that cannot be modified without the consent of each affected holder, and the rights of any holder of a debt security to receive payment of principal of, premium, if any, on and interest on such debt securities, holders of a majority in aggregate principal amount of the debt securities voting as a single class of such series or of all debt securities, as the case may be, then outstanding may waive all defaults with respect to that series or with respect to all securities treated as a single class and rescind and annul such declaration and its consequences, but no waiver or rescission and annulment will extend to or affect any subsequent default.

Outstanding Debt Securities; Determinations of Holders’ Actions

Debt securities outstanding at any time are the debt securities authenticated and delivered by the trustee except for those cancelled by the trustee or delivered to the trustee for cancellation, those debt securities, or portions thereof, for which we have deposited in trust with the trustee or any paying agent a sufficient amount of money for the payment or redemption thereof, those debt securities that have been defeased under the indenture, and those debt securities that have been exchanged for other debt securities issued under the indenture or that have been mutilated, destroyed, lost or stolen and replaced by the trustee. A debt security does not cease to be outstanding because we or an affiliate of ours holds the debt security; provided, that in determining whether the holders of the requisite aggregate principal amount of debt securities have given or concurred in any request, demand, authorization, notice, direction, consent or waiver, debt securities owned by us, any other obligor of the debt securities or any other person directly or indirectly controlling or controlled by or under direct or indirect common control with us or any other obligor on the debt securities, will be disregarded and deemed not to be outstanding for the purpose of any such determination, except for determining whether the trustee shall be protected in relying on any such request, demand, authorization, direction, notice, consent or waiver, only debt securities which the trustee knows are so owned will be so disregarded, and debt securities that have been pledged in good faith may also be regarded as outstanding under certain circumstances.

Satisfaction and Discharge

Each indenture may be discharged and cease to be of further effect as to the applicable debt securities, when:

either:

all debt securities of any series that have been authenticated and all coupons, if any, appertaining thereto have been delivered to the trustee for cancellation, except (i) coupons on bearer securities that meet certain conditions, (ii) debt securities and coupons that have been destroyed, lost or stolen and that have been replaced or paid as provided in the indenture, (iii) coupons relating to debt securities called for redemption and maturing after the relevant redemption date, whose surrender has been waived, and (iv) debt securities and coupons for which payment has been deposited in trust or segregated and held in trust by us and thereafter repaid to us or discharged from such trust; or

all debt securities and certain coupons discussed above that have not been delivered to the trustee for cancellation (i) have become due and payable, (ii) are by their terms due and payable within one year or (iii) are to be called for redemption within one year under arrangements satisfactory to the trustee for the giving of notice of redemption, and in the case of clauses (i) and (iii) in the preceding bullet point, we have deposited or caused to be deposited with the trustee as trust funds the entire amount (other than moneys repaid by the trustee or any paying agent to us under the terms of the indenture) sufficient to pay at maturity or upon redemption all debt securities of such series and coupons not delivered to the trustee for cancellation, including principal (and premium, if any) and any interest due or to become due to such date of maturity or date of redemption;

we have paid or caused to be paid all other sums payable by us under the applicable indenture with respect to the debt securities;

upon demand of and at our cost and expense, the trustee has executed instruments reasonably requested by us acknowledging the satisfaction and discharge of the applicable indenture with respect to the debt securities; and

we have delivered to the trustee an officer’s certificate and an opinion of counsel stating that the conditions precedent to the satisfaction and discharge of the debt securities have been complied with.

Legal Defeasance and Covenant Defeasance

Legal Defeasance

Under the terms of the indentures and unless otherwise provided in a supplemental indenture, we will be deemed to have paid and will be discharged from any and all obligations in respect of the debt securities after we have made the deposit referred to below and the conditions precedent and subsequent set forth below are satisfied, and the provisions of the applicable indenture will cease to be applicable with respect to the debt securities (except for, among other matters, certain rights of the holders to receive payments of principal, premium and interest when due on such debt securities from the trust fund, and our obligations to register the transfer of or exchange of the debt securities, prepare temporary debt securities, replace stolen, lost or mutilated debt securities, maintain paying agents and hold funds for payment in trust, and rights, powers, trusts, duties and immunities with respect to the trustee) if:

we have irrevocably deposited or caused to be deposited with the trustee, in trust, money in an amount and/or non-callable or non-redeemable government securities that will provide funds in amount sufficient, in the opinion of a nationally recognized public accounting firm expressed in a written certification delivered to the trustee, to pay the principal of, premium, if any, and accrued interest on the debt securities until maturity or redemption in accordance with the terms of the applicable indenture and any mandatory sinking fund payments or analogous payments applicable to such debt securities;

no default or event that after notice or lapse of time, or both, would become a default with respect to such debt securities, will have occurred and be continuing on the date of such deposit, or insofar as events of default due to certain events of bankruptcy, insolvency or reorganization in respect of us are concerned, during the period ending on the 123^rd day after the date of such deposit or, if longer, ending on the day following the expiration of the longest preference period applicable to the company with respect to such deposit;

such defeasance or covenant defeasance does not (i) cause the trustee for the debt securities to have a conflicting interest under the terms of the indenture or the Trust Indenture Act or (ii) result in the trust arising from such deposit to constitute, unless it is qualified, a regulated investment company under the Investment Company Act of 1940, as amended;

such defeasance or covenant defeasance does not result in a breach or violation of, or constitute a default under, the indenture or any other agreement or instrument to which we are a party or by which we are bound;

such defeasance or covenant defeasance does not cause any debt securities of such series then listed on any registered national securities exchange under the Exchange Act to be delisted;

we have delivered to the trustee an opinion of counsel stating that (i) we have received from, or there has been published by, the Internal Revenue Service a ruling or (ii) since the date of the indenture there has been a change in the applicable United States federal income tax law to the effect that, and based thereon, holders of the debt securities will not recognize income, gain or loss for federal income tax purposes as a result of such defeasance and will be subject to United States federal income tax on the same amounts and in the same manner and at the same times as would have been the case if such defeasance had not occurred;

such defeasance is effected in compliance with any terms, conditions or limitations which may be imposed on the Company in connection with a supplemental indenture or board resolutions establishing such series of debt securities; and

we shall have delivered to the trustee an officer’s certificate and an opinion of counsel, each stating that all conditions precedent and subsequent provided for in the indenture relating to the defeasance have been complied with.

Covenant Defeasance

Under the terms of the indentures and unless as otherwise provided in a supplemental indenture, we will not need to comply with certain restrictive covenants, and the provisions of the applicable indenture will cease to be applicable with respect to an event of default under the debt securities other than an event of default due to our failure to pay the principal of or interest on the debt securities when due, upon:

the satisfaction of the conditions described above in “–Legal Defeasance and Covenant Defeasance – Legal Defeasance,” other than with respect to the sixth bullet point; and

our delivery to the trustee of an opinion of counsel to the effect that the holders of the debt securities will not recognize income, gain or loss for United States federal income tax purposes as a result of such covenant defeasance and will be subject to United States federal income tax on the same amount and in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred.

If we exercise our option to omit compliance with certain provisions of the applicable indenture as described in the immediately preceding paragraph and the debt securities are declared due and payable because of the occurrence of an event of default that remains applicable, the amount of money and/or non-callable government securities on deposit with the trustee may not be sufficient to pay amounts due on the debt securities at the time of acceleration resulting from such event of default. In such event, we will remain liable for such payments.

Limitation on Individual Liability

No incorporator or past, present or future stockholder, officer or director of ours or any successor corporation, as such, will have any liability for any obligations, covenants or agreements of ours under the debt securities or the indentures or because of any indebtedness evidenced thereby. Each holder of a debt security, by accepting a debt security waives and releases such liability. The waiver and release are part of the consideration for the issuance of the debt securities. Such waiver may not be effective to waive liabilities under the federal securities laws.

Trustee

The accompanying prospectus supplement will specify the trustee for the particular series of debt securities to be issued under the indentures.

At all times, the trustee must be a corporation organized and doing business under the laws of the United States or any state or territory thereof or of the District of Columbia, with authority to exercise corporate trust powers, be subject to the supervision or examination by federal, state, territorial or District of Columbia authority, have at all times a combined capital and surplus of not less than $50,000,000 and not be the Company or any person directly or indirectly controlled or controlled by or under common control with the Company.

If the trustee acquires any conflicting interest, as defined in the Trust Indenture Act, with respect to the debt securities, within 90 days after the trustee has acquired a conflicting interest, which has not been cured or waived, the trustee would generally be required by the Trust Indenture Act to eliminate that conflicting interest or resign as trustee with respect to the debt securities issued under the applicable indenture. If the trustee resigns, we are required to appoint a successor trustee with respect to the affected securities promptly. The trustee and/or certain of its affiliates may provide banking, investment and other services to us.

Notices

Any notices required to be given to the holders of the debt securities will be given by mail to the addresses of the holders in the security register.

Governing Law

The indentures and the debt securities are governed by, and will be construed in accordance with, the laws of the State of New York. The indentures will be subject to the provisions of the Trust Indenture Act that are required to be part of the indentures and will, to the extent applicable, be governed by such provisions.

Book-Entry Delivery and Settlement

Global Debt Securities

We will issue any debt securities in the form of one or more global debt securities in definitive, fully registered, book-entry form. The global debt securities will be deposited with or on behalf of DTC, and registered in the name of Cede & Co., as nominee of DTC. Beneficial interests in the global debt securities will be represented through book-entry accounts of financial institutions acting on behalf of beneficial owners as direct and indirect participants in DTC. Investors may hold interests in the global debt securities through DTC.

DTC has advised us that:

DTC is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered under Section 17A of the Exchange Act.

DTC holds securities that its participants deposit with DTC and facilitates the post-trade settlement among participants of sales and other securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in participants’ accounts, thereby eliminating the need for physical movement of security certificates.

Direct participants include securities brokers and dealers, banks, trust companies, clearing corporations and other organizations.

DTC is a wholly owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries.

Access to the DTC system is also available to others such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies and clearing corporations that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly.

The rules applicable to DTC and its direct and indirect participants are on file with the SEC.

We have provided the description of the operations and procedures of DTC in this prospectus solely as a matter of convenience. These operations and procedures are solely within the control of those organizations and are subject to change by them from time to time. None of us, any underwriters or any trustee takes any responsibility for these operations or procedures, and you are urged to contact DTC or their participants directly to discuss these matters.

We expect that under procedures established by DTC:

upon deposit of the global debt securities with DTC or its custodian, DTC will credit on its internal system the accounts of direct participants designated by any underwriters with portions of the principal amounts of the global debt securities; and

ownership of the debt securities will be shown on, and the transfer of ownership thereof will be effected only through, records maintained by DTC or its nominee, with respect to interests of direct participants, and the records of direct and indirect participants, with respect to interests of persons other than participants.

The laws of some jurisdictions may require that purchasers of securities take physical delivery of those securities in definitive form. Accordingly, the ability to transfer interests in the debt securities represented by a global debt security to those persons may be limited. In addition, because DTC can act only on behalf of its participants, who in turn act on behalf of persons who hold interests through participants, the ability of a person having an interest in debt securities represented by a global debt security to pledge or transfer those interests to persons or entities that do not participate in DTC’s system, or otherwise to take actions in respect of such interest, may be affected by the lack of a physical definitive security in respect of such interest.

So long as DTC or its nominee is the registered owner of a global debt security, DTC or that nominee will be considered the sole owner or holder of the debt securities represented by that global debt security for all purposes under the indenture and under the debt securities. Except as provided below, owners of beneficial interests in a global debt security will not be entitled to have debt securities represented by that global debt security registered in their names, will not receive or be entitled to receive physical delivery of certificated debt securities and will not be considered the owners or holders thereof under the applicable indenture or under the debt securities for any purpose, including with respect to the giving of any direction, instruction or approval to the trustee. Accordingly, each holder owning a beneficial interest in a global debt security must rely on the procedures of DTC and, if that holder is not a direct or indirect participant, on the procedures of the participant through which that holder owns its interest, to exercise any rights of a holder of debt securities under the applicable indenture or a global debt security.

Neither we nor any trustee will have any responsibility or liability for any aspect of the records relating to or payments made on account of debt securities by DTC, or for maintaining, supervising or reviewing any records of those organizations relating to the debt securities.

Payments on the debt securities represented by the global debt securities will be made to DTC or its nominee, as the case may be, as the registered owner thereof. We expect that DTC or its nominee, upon receipt of any payment on the debt securities represented by a global debt security, will credit participants’ accounts with payments in amounts proportionate to their respective beneficial interests in the global debt security as shown in the records of DTC or its nominee. We also expect that payments by participants to owners of beneficial interests in the global debt security held through such participants will be governed by standing instructions and customary practice as is currently the case with securities held for the accounts of customers registered in the names of nominees for such customers. The participants will be responsible for those payments.

Settlement Procedures

Secondary market trading between DTC participants will occur in the ordinary way in accordance with DTC rules and will be settled in immediately available funds.

Certificated Debt Securities

Individual certificates in respect of any debt securities will not be issued in exchange for the global debt securities, except in very limited circumstances. We will issue or cause to be issued certificated debt securities to each person that DTC identifies as the beneficial owner of the debt securities represented by a global debt security upon surrender by DTC of the global debt security if:

DTC notifies us that it is no longer willing or able to act as a depositary for such global debt security or ceases to be a clearing agency registered under the Exchange Act, and we have not appointed a successor depositary within 90 days of that notice or becoming aware that DTC is no longer so registered;

an event of default has occurred and is continuing, and DTC requests the issuance of certificated debt securities; or

subject to DTC’s procedures, we determine not to have the debt securities of such series represented by a global debt security.

Neither we nor any trustee will be liable for any delay by DTC, its nominee or any direct or indirect participant in identifying the beneficial owners of the debt securities. We and any trustee may conclusively rely on, and will be protected in relying on, instructions from DTC or its nominee for all purposes, including with respect to the registration and delivery, and the respective principal amounts, of any certificated debt security to be issued.

DESCRIPTION OF DEPOSITARY SHARES

We may elect to offer fractional interests in shares of our preferred stock, in which case we will issue receipts for depositary shares and each depositary share will represent a fraction of a share of the applicable series of our preferred stock, as set forth in the applicable prospectus supplement. The following summary of the terms of the depositary shares does not purport to be complete and is subject to, and is qualified in its entirety by reference to, the terms of the depositary shares and our preferred stock, as well as the form of the deposit agreement, depositary receipts, our articles and any amendments thereto relating to the applicable series of our preferred stock that will be filed with the SEC. Therefore, you should carefully consider the actual provisions in these documents.

General

Each owner of a depositary share will be entitled, in proportion to the applicable fractional interest in shares of our preferred stock underlying that depositary share, to all rights and preferences of our preferred stock underlying that depositary share. These rights may include dividend, voting, redemption and liquidation rights.

The shares of our preferred stock underlying the depositary shares will be deposited with a bank or trust company selected by us to act as depositary, under a deposit agreement between us, the depositary and the holders of the depositary receipts. The depositary will be the transfer agent, registrar and dividend disbursing agent for the depositary shares. The name and address of the principal executive office of the depositary will be included in the prospectus supplement relating to the issue.

The depositary shares will be evidenced by depositary receipts issued pursuant to the depositary agreement. Holders of depositary receipts agree to be bound by the deposit agreement, which will require holders to take certain actions, such as filing proof of residence and paying certain charges.

Dividends and Other Distributions

The depositary will distribute cash dividends or other cash distributions, if any, received in respect of the series of our preferred stock underlying the depositary shares to the record holders of depositary receipts in proportion to the number of depositary shares owned by those holders on the relevant record date. The relevant record date for depositary shares will be the same date as the record date for our preferred stock.

In the event of a distribution other than in cash, the depositary will distribute property received by it to the record holders of depositary receipts that are entitled to receive the distribution, unless the depositary determines that it is not feasible to make the distribution. If this occurs, the depositary, with our approval, may adopt another method for the distribution, including selling the property and distributing the net cash proceeds to the holders.

Liquidation Preference

If a series of our preferred stock underlying the depositary shares has a liquidation preference, in the event of our voluntary or involuntary liquidation, dissolution or winding-up, holders of depositary shares will be entitled to receive the fraction of the liquidation preference accorded each share of the applicable series of our preferred stock, as set forth in the applicable prospectus supplement.

Redemption

If a series of our preferred stock underlying the depositary shares is subject to redemption, the depositary shares will be redeemed from the proceeds received by the depositary resulting from the redemption, in whole or in part, of our preferred stock held by the depositary. Whenever we redeem any of our preferred stock held by the depositary, the depositary will redeem, as of the same redemption date, the number of depositary shares representing our preferred stock so redeemed. The depositary will mail the notice of redemption to the record holders of the depositary receipts promptly upon receiving the notice from us, unless otherwise provided in the applicable prospectus supplement, prior to the date fixed for redemption of our preferred stock.

After the date fixed for redemption, the depositary shares called for redemption will no longer be outstanding. When the depositary shares are no longer outstanding, all rights of the holders will terminate, except the right to receive money, securities or other property payable upon redemption.

Voting

Upon receipt of notice of any meeting at which the holders of our preferred stock are entitled to vote, the depositary will mail the information contained in the notice of meeting to the record holders of the depositary receipts underlying our preferred stock. Each record holder of those depositary receipts on the record date will be entitled to instruct the depositary as to the exercise of the voting rights pertaining to the amount of our preferred stock underlying that holder’s depositary shares. The record date for the depositary will be the same date as the record date for our preferred stock. The depositary will try, as far as practicable, to vote the shares of our preferred stock underlying the depositary shares in accordance with these instructions. We will agree to take all action that may be deemed necessary by the depositary in order to enable the depositary to vote our preferred stock in accordance with these instructions. The depositary will not vote our preferred stock to the extent that it does not receive specific instructions from the holders of depositary receipts.

Withdrawal of Preferred Stock

Owners of depositary shares will be entitled to receive, upon surrender of depositary receipts at the principal office of the depositary and payment of any unpaid amount due to the depositary, the number of whole shares of our preferred stock underlying their depositary shares.

Partial shares of our preferred stock will not be issued. Holders of our preferred stock will not be entitled to deposit the shares under the deposit agreement or to receive depositary receipts evidencing depositary shares for our preferred stock.

Amendment and Termination of the Deposit Agreement

The form of depositary receipt evidencing the depositary shares and any provision of the deposit agreement may be amended by agreement between the depositary and us. However, any amendment that materially and adversely alters the rights of the holders of depositary shares, other than fee changes, will not be effective unless the amendment has been approved by the holders of at least a majority of the outstanding depositary shares. The deposit agreement may be terminated by the depositary or us only if:

all outstanding depositary shares have been redeemed; or

there has been a final distribution of our preferred stock in connection with our dissolution and such distribution has been made to all holders of depositary shares.

Charges of Depositary

We will pay all United States transfer and other taxes and governmental charges arising solely from the existence of the depositary arrangement. We will also pay charges of the depositary in connection with:

the initial deposit of our preferred stock;

the initial issuance of the depositary shares;

any redemption of our preferred stock; and

all withdrawals of our preferred stock by owners of depositary shares.

Holders of depositary receipts will pay transfer, income and other taxes and governmental charges and other specified charges as provided in the deposit agreement for their accounts. If these charges have not been paid, the depositary may:

refuse to transfer depositary shares;

withhold dividends and distributions; and

sell the depositary shares evidenced by the depositary receipt.

Miscellaneous

The depositary will forward to the holders of depositary receipts all reports and communications we deliver to the depositary that we are required to furnish to the holders of our preferred stock. In addition, the depositary will make available for inspection by holders of depositary receipts at the principal office of the depositary, and at such other places as it may from time to time deem advisable, any reports and communications we deliver to the depositary as the holder of our preferred stock.

Neither we nor the depositary will be liable if either we or the depositary are prevented or delayed by law or any circumstance beyond the control of either the depositary or us in performing our respective obligations under the deposit agreement. Our obligations and the depositary’s obligations will be limited to the performance in good faith of our or the depositary’s respective duties under the deposit agreement. Neither we nor the depositary will be obligated to prosecute or defend any legal proceeding in respect of any depositary shares or our preferred stock unless satisfactory indemnity is furnished. The depositary and we may rely on:

written advice of counsel or accountants;

information provided by holders of depositary receipts or other persons believed in good faith to be competent to give such information; and

documents believed to be genuine and to have been signed or presented by the proper party or parties.

Resignation and Removal of Depositary

The depositary may resign at any time by delivering a notice to us. We may remove the depositary at any time. Any such resignation or removal will take effect upon the appointment of a successor depositary and its acceptance of such appointment. The successor depositary must be appointed within 60 days after delivery of the notice for resignation or removal. The successor depositary must be a bank and trust company having its principal office in the United States of America and having a combined capital and surplus of at least $50,000,000.

DESCRIPTION OF WARRANTS

General

We may issue warrants in one or more series to purchase debt securities, common stock, preferred stock or any combination of these securities. Warrants may be issued independently or together with any underlying securities and may be attached to or separate from the underlying securities. We will issue each series of warrants under a separate warrant agreement to be entered into between us and a warrant agent. The warrant agent will act solely as our agent in connection with the warrants of such series and will not assume any obligation or relationship of agency for or on behalf of holders or beneficial owners of warrants. The following sets forth some of the general terms and provisions of the warrants. Further terms of the warrants and the applicable warrant agreement will be stated in the applicable prospectus supplement. The following description and any description of the warrants in a prospectus supplement are not complete and are subject to and qualified in their entirety by reference to the terms and provisions of the warrant agreement and related form of warrant certificate representing the warrants, which we will file with the SEC in connection with an issuance of any warrants.

The applicable prospectus supplement will describe the terms of any warrants, including the following, as may be applicable:

the title of the warrants;

the consideration for which we will issue the warrants, including the applicable currency or currencies;

anti-dilution provisions to adjust the number or amount of shares of our common stock or other securities to be delivered upon exercise of the warrants;

the designation and terms of the underlying securities purchasable upon exercise of the warrants;

the price at which and the currency or currencies in which investors may purchase the underlying securities purchasable upon exercise of the warrants;

any other terms of the warrants, including terms, procedures and limitations relating to the exchange, transfer and exercise of the warrants.

Warrant certificates may be exchanged for new warrant certificates of different denominations, and warrants may be exercised at the warrant agent’s corporate trust office or any other office indicated in the applicable prospectus supplement. Prior to the exercise of their warrants, holders of warrants exercisable for shares of our common stock or preferred stock will not have any rights of holders of our common stock or preferred stock purchasable upon such exercise, including any rights to vote such shares or to receive any distributions or dividends thereon.

Exercise of Warrants

A warrant will entitle the holder to purchase for cash an amount of securities at an exercise price that will be stated in, or that will be determinable as described in, the applicable prospectus supplement. Warrants may be exercised at any time prior to the close of business on the expiration date and in accordance with the procedures set forth in the applicable prospectus supplement. Upon and after the close of business on the expiration date, unexercised warrants will be void and have no further force, effect or value.

DESCRIPTION OF PURCHASE CONTRACTS AND PURCHASE UNITS

We may issue purchase contracts for the purchase or sale of common stock, preferred stock or debt securities issued by us as specified in the applicable prospectus supplement. Each purchase contract will entitle the holder thereof to purchase or sell, and obligate us to sell or purchase on specified dates, such securities at a specified purchase price, which may be based on a formula, all as set forth in the applicable prospectus supplement. We may, however, satisfy our obligations, if any, with respect to any purchase contract by delivering the cash value of such purchase contract or the cash value of the securities otherwise deliverable, as set forth in the applicable prospectus supplement. The applicable prospectus supplement will also specify the methods by which the holders may purchase or sell such securities, and any acceleration, cancellation or termination provisions or other provisions relating to the settlement of a purchase contract. The price per security and the number of securities may be fixed at the time the purchase contracts are entered into or may be determined by reference to a specific formula set forth in the applicable purchase contracts.

The purchase contracts may be issued separately or as part of units consisting of a purchase contract and debt securities, or any other securities offered under this prospectus and described in the applicable prospectus supplement or any combination of the foregoing, securing the holders’ obligations to purchase the securities under the purchase contracts, which we refer to herein as purchase units. The purchase contracts may require holders to secure their obligations under the purchase contracts in a specified manner. The purchase contracts also may require us to make periodic payments to the holders of the purchase contracts or the purchase units, as the case may be, or vice versa, and those payments may be unsecured or pre-funded on some basis.

The prospectus supplement relating to any offering of purchase contracts or purchase units will contain the specific terms of the purchase contracts or purchase units. These terms may include, without limitation, the following:

whether the purchase contracts obligate the holder or us to purchase or sell, or both purchase and sell, the securities subject to purchase under the purchase contract, and the nature and amount of each of those securities, or the method of determining those amounts;

whether the purchase contracts are to be prepaid or not;

whether the purchase contracts are to be settled by delivery, or by reference or linkage to the value, performance or level of the securities subject to purchase under the purchase contract;

a discussion of the material United States federal income tax considerations applicable to the purchase contracts or purchase units;

whether the purchase contracts or purchase units will be issued in fully registered or global form; and

any other terms of the purchase contracts or purchase units and any securities subject to such purchase contracts.

The description in the applicable prospectus supplement of any purchase contracts and purchase units we offer will not necessarily be complete and is subject to, and will be qualified in its entirety by reference to, the applicable purchase contract or unit agreement, which will be filed with the SEC in connection with any offering of such securities.

DESCRIPTION OF SUBSCRIPTION RIGHTS

We may issue subscription rights to purchase our common stock, preferred stock or debt securities. These subscription rights may be issued independently or together with any other security offered hereby and may or may not be transferable by the stockholder receiving the subscription rights in such offering. In connection with any offering of subscription rights, we may enter into a standby arrangement with one or more underwriters or other purchasers pursuant to which the underwriters or other purchasers may be required to purchase any securities that have not been subscribed for after such offering.

The applicable prospectus supplement will describe the specific terms of any offering of subscription rights for which this prospectus is being delivered, including the following:

the price, if any, for the subscription rights;

the exercise price payable for each share of our common stock or preferred stock or for debt securities upon the exercise of the subscription rights;

the number of subscription rights issued to each stockholder;

DESCRIPTION OF UNITS

We may issue units comprised of any combination of two or more of the other securities described in this prospectus and as specified in the applicable prospectus supplement. Each unit will be issued so that the holder of the unit is also the holder, with rights and obligations of a holder, of each security included in the unit. The units may be issued under unit agreements to be entered into between us and a unit agent.

The applicable prospectus supplement will specify the terms of the units, including:

the designation and terms of the units and of any of the securities comprising the units, including whether and under what circumstances the securities comprising the units may be held or transferred separately;

a description of the terms of any unit agreement governing the units;

a description of the provisions for the issuance, payment, settlement, transfer or exchange of the units or of the securities comprising the units;

a discussion of material United States federal income tax considerations, if applicable; and

whether the units, if issued as a separate security, will be issued in fully registered or global form.

The applicable prospectus supplement will describe the terms of any units. The description in the applicable prospectus supplement of any units we offer will not necessarily be complete and is subject to, and will be qualified in its entirety by reference to, the applicable unit agreement, which will be filed with the SEC in connection with any offering of units.

PLAN OF DISTRIBUTION

We may sell the securities offered under this prospectus from time to time pursuant to underwritten public offerings, negotiated transactions, block trades or a combination of these methods or through underwriters, dealers or agents or directly to one or more purchasers. The securities may be distributed from time to time in one or more transactions (or in any combination) at:

a fixed price or prices, which may be changed;

market prices prevailing at the time of sale;

prices related to the prevailing market price; or

negotiated prices.

For each type and series of securities offered, the applicable prospectus supplement will set forth the terms of the offering, including, without limitation:

the public offering price;

the names of any underwriters, dealers or agents and the amount of securities underwritten or purchased by each of them, if any;

any delayed delivery arrangements;

the proceeds from the sale of securities to us and the use of proceeds from the sale of the securities;

any underwriting discounts, concessions, commissions, agency fees or other compensation payable to underwriters, dealers or agents;

any discounts or concessions allowed or re-allowed or repaid to dealers;

estimated offering expenses; and

the securities exchanges on which the securities will be listed, if any.

We may grant underwriters options to purchase additional securities at the public offering price, with additional underwriting commissions or discounts, as applicable, set forth in the prospectus supplement. The terms of any such option will be set forth in the prospectus supplement for those securities.

Underwriters or agents may make sales in privately negotiated transactions and/or any other method permitted by law, including sales deemed to be an “at-the-market” offering as defined in Rule 415 under the Securities Act, which includes sales made directly on Nasdaq, the existing trading market for our common stock, or sales made to or through a market maker other than on an exchange.

We may issue to our existing security holders, though a dividend or similar distribution, rights to purchase shares of our common stock or preferred stock, which may or may not be transferable. In any distribution of rights to our existing security holders, 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 facilitate the distribution of the unsubscribed securities. The applicable prospectus supplement will describe the specific terms of any offering of our common stock or preferred stock through the issuance of rights including, if applicable, the material terms of any standby underwriting agreement or purchase agreement.

Sales Through Underwriters, Dealers or Agents; Direct Sales

If we use underwriters in any sale of securities offered under this prospectus, the underwriters will buy the securities for their own account, including through underwriting, purchase, security lending or repurchase agreements with us. The underwriters may then resell the securities in one or more transactions at a fixed public offering price or at varying prices determined at the time of sale or thereafter. Unless otherwise indicated in the prospectus supplement, the obligations of the underwriters to purchase the securities will be subject to certain conditions and the underwriters will be obligated to purchase all the securities offered if they purchase any securities. The public offering price for the securities and any discounts or concessions allowed or re-allowed or paid to dealers may be changed from time to time.

If we use dealers in any sale of securities offered under this prospectus, the securities will be sold to such dealers as principals. The dealers may then resell the securities to the public at varying prices to be determined by such dealers at the time of resale.

If agents are used in any sale of securities offered under this prospectus, they will use their reasonable best efforts to solicit purchases for the period of their appointment or to sell our securities on a continuing basis. If required, the prospectus supplement relating to any particular offering of securities will name any agents designated to solicit offers and will include information about any commissions they may be paid in that offering.

If securities offered under this prospectus are sold directly, no underwriters, dealers or agents would be involved.

We are not making an offer of securities in any state that does not permit such an offer. If we sell securities through dealers or agents, or directly, the terms of any such sales will be described in the applicable prospectus supplement.

Delayed Delivery Contracts

We may authorize underwriters, dealers or agents to solicit offers from certain institutions whereby the institution contractually agrees to purchase the securities offered under this prospectus from us on a future date at a specific price. This type of contract may be made only with institutions that we specifically approve. Such institutions could include banks, insurance companies, pension funds, investment companies and educational and charitable institutions. The underwriters, dealers or agents will not be responsible for the validity or performance of these contracts. The prospectus supplement relating to the contracts will set forth the price to be paid for offered securities pursuant to such contracts, the commission payable for solicitation of the contracts and the date or dates in the future for delivery of offered securities pursuant to the contracts.

Market Making, Stabilization and Other Transactions

Each issue of a new series of securities, other than issuances of our common stock, will not have an established trading market, except as indicated in the applicable prospectus supplement. Unless indicated in the applicable prospectus supplement, we do not expect to list the offered securities on a securities exchange, except for our common stock, which is listed on Nasdaq. We can provide no assurance as to whether any of our securities will have a liquid trading market.

In order to facilitate the offering of any of the securities offered under this prospectus, the underwriters with respect to any such offering may, as described in the prospectus supplement and in accordance with applicable law, engage in transactions that stabilize, maintain or otherwise affect the price of the securities or any other securities the prices of which may be used to determine payments on these securities. Stabilizing transactions involve bids to purchase the underlying security in the open market for the purpose of preventing or delaying a decline in the price of the securities. Syndicate covering transactions involve purchases of the securities in the open market after the distribution has been completed in order to cover syndicate short positions. Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when the securities originally sold by the syndicate member are purchased in a stabilizing or syndicate covering transaction to cover syndicate short positions. Any of these activities may have the effect of raising or maintaining the market price of our securities or preventing or delaying a decline in the market price of our securities. As a result, the market price of the securities may be higher than it otherwise would be in the absence of these transactions. The underwriters are not required to engage in these activities, and may end any of these activities at any time, all as described in the applicable prospectus supplement.

Any person participating in the distribution of securities will be subject to applicable provisions of the Exchange Act and the rules and regulations under the Exchange Act, including Regulation M, which may limit the timing of transactions involving the securities offered under this prospectus. Furthermore, Regulation M may restrict the ability of any person engaged in the distribution of such securities to engage in market-making activities with respect to the particular securities being distributed. All of the above may affect the marketability of the securities offered under this prospectus and the ability of any person or entity to engage in market-making activities with respect to such securities.

Derivative Transactions and Hedging

We, the underwriters or other agents engaged by us may engage in derivative transactions involving the securities. These derivatives may consist of short sale transactions and other hedging activities. The underwriters or agents may acquire a long or short position in the securities, hold or resell securities acquired and purchase options or futures on the securities and other derivative instruments with returns linked or related to changes in the price of the securities. In order to facilitate these derivative transactions, we may enter into security lending or repurchase agreements with the underwriters or agents. The underwriters or agents may effect the derivative transactions through sales of the securities to the public, including short sales, or by lending the securities in order to facilitate short sale transactions by others. The underwriters or agents may also use the securities purchased or borrowed from us or others (or, in the case of derivatives, securities received from us in settlement of those derivatives) to directly or indirectly settle sales of the securities or close out any related open borrowings of the securities.

General Information

We expect that any agreements we may have with underwriters, dealers and agents will include provisions indemnifying them against certain civil liabilities, including certain liabilities under the Securities Act, or providing for contribution with respect to payments that they may be required to make. An underwriter, dealer or agent, or any of their affiliates, may be a customer of, or otherwise engage in transactions with or perform services for us in the ordinary course of business.

The specific terms of any lock-up provisions with respect to any given offering will be described in the applicable prospectus supplement.

Under the securities laws of various states, the securities offered under this prospectus may be sold in those states only through registered or licensed brokers or dealers. In addition, in various states the securities offered under this prospectus may not be offered and sold unless such securities have been registered or qualified for sale in the state or an exemption from such registration or qualification is available. We are not making an offer of securities in any state that does not permit such an offer.

LEGAL MATTERS

Unless otherwise indicated in the applicable prospectus supplement, the validity of the securities will be passed upon for us by Covington & Burling LLP, Washington, D.C. If legal matters are passed upon by counsel for the underwriters, dealers or agents, if any, such counsel will be named in the prospectus supplement relating to such offering.
