TABLE OF CONTENTS

ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement on Form S-3 that we filed with the Securities and Exchange Commission, or the SEC, under the Securities Act of 1933, as amended, of the Securities Act, using a “shelf” registration process. Under this process, we may, from time to time, offer and sell, either individually or in combination, in one or more offerings, up to a total dollar amount of $240.0 million of any of the securities described in this prospectus.

This prospectus provides a general description of the securities we may offer. Each time we offer and sell securities under this prospectus, we will, to the extent required by law, provide a prospectus supplement that will contain specific information about the terms of that offering. We may also authorize one or more free writing prospectuses to be provided to you that may contain material information relating to a particular offering. The prospectus supplement and any related free writing prospectus may also add, update or change information contained in this prospectus or in any documents that we have incorporated by reference into this prospectus with respect to that offering. To the extent there is a conflict between any statement contained in this prospectus, any applicable prospectus supplement, any related free writing prospectus or any document incorporated by reference into this prospectus, the statement in the document having the later date modifies or supersedes the earlier statement.

The information appearing in this prospectus, any applicable prospectus supplement or any related free writing prospectus is accurate only as of the date on the front of the document, and any information we have incorporated by reference is accurate only as of the date of the document incorporated by reference, regardless of the time of delivery of this prospectus, any applicable prospectus supplement or any related free writing prospectus, or the time of any sale of a security. Our business, financial condition, results of operations and prospects may have changed since those dates.

You should rely only on the information contained in, or incorporated by reference into, this prospectus and any applicable prospectus supplement, or the information contained in any free writing prospectus we have authorized for use in connection with a specific offering. We have not authorized anyone to provide you with different or additional information. This prospectus is neither an offer to sell nor a solicitation of an offer to buy any securities other than those registered by this prospectus, nor is it an offer to sell or a solicitation of an offer to buy securities where an offer or solicitation would be unlawful.

As permitted by SEC rules and regulations, the registration statement of which this prospectus forms a part includes additional information not contained in this prospectus. This prospectus also contains summaries of certain provisions of the documents described herein, but all summaries are qualified in their entirety by reference to the actual documents. You may read the registration statement and the other reports we file with the SEC, and you may obtain copies of the actual documents summarized herein (if and when filed with the SEC), at the SEC’s website. See “Where You Can Find More Information.”

The representations, warranties and covenants made by us in any agreement that is filed as an exhibit to any document incorporated by reference into this prospectus were made solely for the benefit of the parties to such agreement, including for the purpose of allocating risks among such parties, and should not be deemed to be a representation, warranty or covenant to you. Moreover, such representations, warranties or covenants do not purport to be accurate as of any date other than when made. Accordingly, such representations, warranties and covenants should not be relied on as accurately representing the current state of our affairs.

MARKET, INDUSTRY AND OTHER DATA

This prospectus contains estimates, projections and other information concerning our industry, our business and the markets for our diagnostic tests, including data regarding the estimated size of those markets and their projected growth rates, as well as market research, estimates and forecasts prepared by our management. We obtained the industry, market and other data throughout this prospectus from our own internal estimates and research, as well as from publicly available information, industry publications and research, surveys and studies conducted by third-parties, including governmental agencies.

Information that is based on estimates, forecasts, projections, market research or similar methodologies is inherently subject to uncertainties and actual events or circumstances may differ materially from events and circumstances that are assumed in this information based on various factors, including those discussed under the heading “Risk Factors” and elsewhere in this prospectus and in the documents incorporated by reference. We believe that these sources and estimates are reliable but have not independently verified them and cannot guarantee their accuracy or completeness. We caution you not to give undue weight to such projections, assumptions and estimates.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus and the information incorporated by reference contain “forward-looking statements” that involve risks and uncertainties. Our actual results could differ materially from those discussed in the forward-looking statements. All statements that are not purely historical are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”) and Section 21E of the Securities Exchange Act of 1934, as amended, (the “Exchange Act”). Forward-looking statements are often identified by the use of words such as, but not limited to, “anticipate,” “believe,” “can,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “plan,” “project,” “seek,” “should,” “strategy,” “target,” “will,” “would” and similar expressions or variations intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. These statements are based on the beliefs and assumptions of our management based on information currently available to management. Such forward-looking statements are subject to risks, uncertainties and other important factors that could cause actual results and the timing of certain events to differ materially from future results expressed or implied by such forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, those identified below and those discussed in the Risk Factors sections and elsewhere in our Annual Reports on Form 10-K and in our Quarterly Reports on Form 10-Q and in the other periodic reports and other filings that we file from time to time with the SEC. These factors and the other cautionary statements made in this prospectus and the documents incorporated by reference herein should be read as being applicable to all related forward-looking statements whenever they appear in this prospectus. The disclosure in this prospectus, including any forward-looking statement, speaks only as of its date, the date of this prospectus, or the date of any document incorporated by reference into this prospectus, as applicable. We disclaim any intention or obligation to update or revise any forward-looking statement, whether as a result of new information, future events or otherwise, except as required by law.

The forward-looking statements in this prospectus and the information incorporated by reference include, among other things, statements about:

Please consider our forward-looking statements in light of those risks as you read this prospectus supplement, and the accompanying prospectus and the information incorporated into each by reference. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. Given these uncertainties, you should not place undue reliance on these forward-looking statements.

If one or more of these or other risks or uncertainties materializes, or if our underlying assumptions prove to be incorrect, actual results may vary materially from what we anticipate. All subsequent written and oral forward-looking statements attributable to us or individuals acting on our behalf are expressly qualified in their entirety by this note. Before purchasing any shares of common stock, you should consider carefully all of the risk factors set forth or referred to in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference that could cause actual results to differ.

This summary is not complete and does not contain all the information you should consider before investing in our securities pursuant to this prospectus. Before making an investment decision, please carefully read this entire prospectus and the documents incorporated by reference into this prospectus, including the “Risk Factors” section of our most recent Annual Report on Form 10-K and any subsequent Quarterly Reports on Form 10-Q and our financial statements and the related notes incorporated by reference into this prospectus.

Overview

We are a molecular diagnostics company focused on developing and commercializing proprietary laboratory-developed tests (“LDTs”) to serve unmet medical needs across the cancer care continuum. Our mission is to provide actionable information to physicians and patients at critical decision points to optimize diagnosis and treatment decisions, improve patient outcomes, and reduce overall cost of care. We have prioritized lung cancer as our first indication. Lung cancer remains the leading cause of cancer death in the United States, despite the availability of molecular testing and novel therapies to treat patients.

Our first commercial diagnostic test is a proprietary treatment stratification test called DetermaRx™ that identifies which patients with early stage non-small cell lung cancer may benefit from chemotherapy, resulting in a significantly higher, five-year survival rate. We are also developing multi-gene molecular, laboratory-developed diagnostic tests that we have branded as DetermaIO™. DetermaIO™ is a proprietary gene expression assay with promising data supporting its potential to help identify patients likely to respond to checkpoint inhibitor drugs. This new class of drugs modulate the immune response and show activity in multiple solid tumor types including non-small cell lung cancer (NSCLC), and triple negative breast cancer (TNBC). DetermaIO™ is presently available for research use but one of our goals is to complete development of that assay and to make it available for clinical use later this year. We also perform assay development and clinical testing services for pharmaceutical and biotechnology companies.

We recently added to our diagnostic test pipeline DetermaCNI™, a patented, blood-based test for immunotherapy monitoring. DetermaCNI™ was developed by Chronix Biomedical, Inc., which we acquired through a merger in April 2021. We plan to make DetermaCNI™ available initially as a research tool.

Other tests in our development pipeline include DetermaTx™, a test that we are targeting for commercial launch later this year and that is intended to compliment DetermaIO™ by assessing the mutational status of a tumor to help identify the appropriate targeted therapy. We also plan to initiate the development of DetermaMx™ as a blood based test to monitor cancer patients for recurrence of their disease.

Corporate Information

Our website is www.oncocyte.com. Information contained on, or that can be accessed through, our website, is not, and shall not be deemed to be, incorporated in this prospectus supplement or considered a part thereof.

RISK FACTORS

Investing in our securities involves a high degree of risk and uncertainty. Before making an investment decision with respect to our securities, we urge you to carefully consider the risks, uncertainties and assumptions described in this prospectus, the applicable prospectus supplement and the documents incorporated by reference herein and therein, including the risks described in Part I, Item 1A. Risk Factors of our most recent Annual Report on Form 10-K and in our subsequent Quarterly Reports on Form 10-Q filed with the SEC. You should also refer to the other information contained in this prospectus and the applicable prospectus supplement and the documents incorporated by reference into this prospectus and the applicable prospectus supplement, including our financial statements and the notes to those statements and the information set forth in the section entitled “Special Note Regarding Forward-Looking Statements.”

If one or more of the adverse events relevant to those risks and uncertainties actually occurs, our business, financial condition, results of operations, cash flows or prospects could be materially adversely affected. This could cause the trading price of our securities to decline, and you could lose all or part of your investment. Additional risks and uncertainties not presently known to us or that we currently deem immaterial also may have similar adverse effects on us.

USE OF PROCEEDS

Except as described in any prospectus supplement in connection with a specific offering, we intend to use the net proceeds from our sale of the securities offered under this prospectus for working capital and general corporate purposes. The principal purposes for which we intend to use the net proceeds from a specific offering and the approximate amounts intended to be used for each such purpose will be set forth in the prospectus supplement relating to that offering.

DIVIDEND POLICY

We have never paid cash dividends on our capital stock and we do not anticipate paying cash dividends in the foreseeable future as we intend to retain our capital resources for reinvestment in our business. Under an existing credit agreement with Silicon Valley Bank, we have agreed not to pay dividends or to make any distributions or to redeem to repurchase any capital stock without Silicon Valley Bank’s prior written consent. Any future determination to pay cash dividends will be at the discretion of our board of directors and will be dependent upon the repayment of the loans from Silicon Valley Bank, our financial condition, results of operations, capital requirements and other factors as our board of directors deems relevant.

SECURITIES THAT MAY BE OFFERED

We may offer shares of common stock, shares of preferred stock, warrants, units consisting of a combination of the foregoing securities or any other combination of the foregoing. We may offer up to $240.0 million of securities under this prospectus. The prices and terms of any offering will be determined by market conditions at the time of offering. We may issue preferred stock that is exchangeable for or convertible into common stock or any of the other securities that may be sold under this prospectus. Each time we offer securities under this prospectus, we will provide offerees with a prospectus supplement that will describe the specific amounts, prices and other important terms of the securities being offered.

The summaries below provide a general description of the securities we may offer and are not intended to be complete. The particular terms of any security will be described in the applicable prospectus supplement.

DESCRIPTION OF CAPITAL STOCK

The following description of our capital stock, together with any additional information we include in any applicable prospectus supplement, documents incorporated by reference or any related free writing prospectus, summarizes the material terms and provisions of our common stock that we may offer, and the preferred stock that we may offer, under this prospectus. We will describe the particular terms of any class or series of these securities in more detail in the applicable prospectus supplement. The description of our capital stock below is summarized from, and qualified in its entirety by reference to, our Articles of Incorporation and our Bylaws, in each case, as amended and as in effect on the date of this prospectus, each of which has been publicly filed with the SEC. Certain terms of our capital stock described below are also based on the California Corporations Code as in existence on the date of this prospectus, and may be affected by future amendments to such code.

General

Our Articles of Incorporation currently authorizes the issuance of up to 150,000,000 shares of common stock, no par value, and up to 5,000,000 shares of preferred stock, no par value. As of May 10, 2021, there were 89,833,751 shares of common stock outstanding.

Common Stock

Each holder of record of common stock is entitled to one vote for each outstanding share owned, on every matter properly submitted to the shareholders for their vote.

Subject to any dividend rights of holders of any of the preferred stock that we may issue from time to time, holders of common stock are entitled to any dividend declared by our board of directors out of funds legally available for that purpose. We have never paid cash dividends on our capital stock and we do not anticipate paying cash dividends in the foreseeable future as we intend to retain our capital resources for reinvestment in our business.

Subject to the prior payment of any liquidation preference to holders of any preferred stock that we may issue from time to time, holders of common stock are entitled to receive on a pro rata basis all of our remaining assets available for distribution to the holders of common stock in the event of the liquidation, dissolution, or winding up of our operations. Holders of our common stock do not have any preemptive, subscription, or redemption rights. All of the outstanding shares of our common stock are fully paid and non-assessable. The shares of common stock offered under this prospectus or upon the conversion of any preferred stock or exercise of any warrants offered pursuant to this prospectus, when paid for and issued in accordance with the applicable definitive documents under which they are to be issued, will also be fully paid and non-assessable.

Our common stock is listed on the Nasdaq under the symbol “OCX.”

The transfer agent and registrar for our common stock is American Stock Transfer & Trust Company, LLC, 6201 15th Avenue, Brooklyn, New York 11219.

Preferred Stock

We may issue preferred stock in one or more series, at any time, with such rights, preferences, privileges and restrictions as our board of directors may determine, all without further action of our shareholders. Any series of preferred stock which may be authorized by our board of directors in the future may be senior to and have greater rights and preferences than our common stock. There are no shares of preferred stock presently outstanding and we have no present plan, arrangement, or commitment to issue any preferred stock.

The rights, privileges, preferences and restrictions of any class or series of preferred stock may be subordinated to, pari passu with or senior to any of those of any present or future class or series of preferred stock or common stock. Our board of directors is also expressly authorized to increase or decrease the number of shares of any series, but subsequent to the issue of shares of that series the number of shares of the series may not be decreased below the number of such shares then outstanding. The issuance of preferred stock may have the effect of decreasing the market price of our common stock and may adversely affect the voting power of holders of our common stock and reduce the likelihood that holders of our common stock will receive dividend payments and payments upon liquidation. In addition, the issuance of preferred stock could have the effect of delaying, deferring or preventing a change in our control or other corporate action.

The particular terms of each class or series of preferred stock that we may offer under this prospectus, including redemption privileges, liquidation preferences, voting rights, dividend rights or conversion rights, will be more fully described in the applicable prospectus supplement relating to the preferred stock offered thereby. The applicable prospectus supplement will specify the terms of the class or series of preferred stock we may offer, including:

DESCRIPTION OF WARRANTS

General

We may offer warrants for the purchase of shares of common stock, shares of preferred stock or the other securities registered hereby, in one or more series. We may issue the warrants by themselves or together with common stock, preferred stock, other warrants or units, and the warrants may be attached to or separate from any offered securities. While the terms we have summarized below will apply generally to any warrants that we may offer under this prospectus, we will describe in particular the terms of any series of warrants that we may offer in more detail in the applicable prospectus supplement and any applicable free writing prospectus. The terms of any warrants offered by a prospectus supplement may differ from the terms described below.

We will file as an exhibit to the registration statement of which this prospectus forms a part, or will incorporate by reference from another report that we file with the SEC, the form of warrant or warrant agreement, which may include a form of warrant certificate, as applicable, that describes the terms of the particular series of warrants we may offer before the issuance of the related series of warrants. We may issue the warrants under a warrant agreement that we will enter into with a warrant agent to be selected by us. The warrant agent will act solely as our agent in connection with the warrants and will not assume any obligation or relationship of agency or trust for or with any registered holders of warrants or beneficial owners of warrants. The following summary of material provisions of the warrants and warrant agreements are subject to, and qualified in their entirety by reference to, all the provisions of the form of warrant or warrant agreement and warrant certificate applicable to a particular series of warrants. We urge you to read the applicable prospectus supplement and any related free writing prospectus, as well as the complete form of warrant or the warrant agreement and warrant certificate, as applicable, that contain the terms of the warrants.

The particular terms of any issue of warrants will be described in the prospectus supplement relating to the issue. Those terms may include:

Each warrant will entitle its holder to purchase the number of securities at the exercise price set forth in, or calculable as set forth in, the applicable prospectus supplement. The warrants may be exercised as set forth in the prospectus supplement relating to the warrants offered. Unless we otherwise specify in the applicable prospectus supplement, warrants may be exercised at any time up to the close of business on the expiration date set forth in the prospectus supplement relating to the warrants offered thereby. After the close of business on the expiration date, unexercised warrants will become void.

We will specify the place or places where, and the manner in which, warrants may be exercised in the form of warrant, warrant agreement or warrant certificate and applicable prospectus supplement. Upon receipt of payment and the warrant or warrant certificate, as applicable, properly completed and duly executed at the corporate trust office of any warrant agent, or any other office (including ours) indicated in the prospectus supplement, we will, as soon as practicable, issue and deliver the securities purchasable upon such exercise. If less than all of the warrants (or the warrants represented by such warrant certificate) are exercised, a new warrant or a new warrant certificate, as applicable, will be issued for the remaining amount of warrants. If we so indicate in the applicable prospectus supplement, holders of the warrants may surrender securities as all or part of the exercise price for warrants.

Prior to the exercise of any warrants to purchase common stock or preferred stock, holders of the warrants will not have any of the rights of holders of common stock or preferred stock purchasable upon exercise, including the right to vote or to receive any payments of dividends or payments upon our liquidation, dissolution or winding up on the common stock or preferred stock purchasable upon exercise, if any.

DESCRIPTION OF UNITS

The following description, together with the additional information we may include in any applicable prospectus supplement, summarizes the material terms and provisions of the units that we may offer under this prospectus. While the terms we have summarized below will apply generally to any units that we may offer under this prospectus, we will describe the particular terms of any series of units in more detail in the applicable prospectus supplement and any related free writing prospectus. The terms of any units offered by a prospectus supplement may differ from the terms described below.

We will file as an exhibit to the registration statement of which this prospectus forms a part, or will incorporate by reference from another report we file with the SEC, the form of unit agreement that describes the terms of the series of units we may offer under this prospectus, and any supplemental agreements, before the issuance of the related series of units. The following summaries of material terms and provisions of the units are subject to, and qualified in their entirety by reference to, all the provisions of the unit agreement and any supplemental agreements applicable to a particular series of units. We urge you to read the applicable prospectus supplement and any related free writing prospectus, as well as the complete unit agreement and any supplemental agreements that contain the terms of the units.

General

We may offer units comprised of any combination of our common stock, preferred stock, warrants or other units, in one or more series. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately, at any time or at any time before a specified date.

We will describe in the applicable prospectus supplement the terms of the series of units, including:

The provisions described in this section, as well as those described in the sections of this prospectus titled “Description of Capital Stock” and “Description of Warrants” will apply to each unit and to any common stock, preferred stock or warrant included in each unit, respectively.

Enforceability of Rights by Holders of Units

Each unit agent will act solely as our agent under the applicable unit agreement and will not assume any obligation or relationship of agency or trust with any holder of any unit. A single bank or trust company may act as unit agent for more than one series of units. A unit agent will have no duty or responsibility in case of any default by us under the applicable unit agreement or unit, including any duty or responsibility to initiate any proceedings at law or otherwise, or to make any demand upon us. Any holder of a unit may, without the consent of the related unit agent or the holder of any other unit, enforce by appropriate legal action its rights as holder under any security included in the unit.

We and any unit agent (including any of its agents) may treat the registered holder of any unit certificate as an absolute owner of the units evidenced by that certificate for any purpose and as the person entitled to exercise the rights attaching to the units so requested, despite any notice to the contrary.

PLAN OF DISTRIBUTION

We may sell our securities directly to one or more investors. We may also sell our securities through agents designated from time to time or to or through underwriters or dealers. The applicable prospectus supplement and any related free writing prospectus will describe the terms of the offering of the securities, including, to the extent applicable:

We may distribute our securities from time to time in one or more transactions at:

Agents

We may designate agents who agree to use their reasonable efforts to solicit purchases of our securities for the period of their appointment or to sell our securities on a continuing basis. We will name any agent involved in the offering and sale of securities and we will describe any fees or commissions we will pay the agent in the applicable prospectus supplement.

Underwriters

If we use underwriters for a sale of securities, the underwriters will acquire the securities for their own account. The underwriters may resell the securities in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. The obligations of the underwriters to purchase the securities will be subject to the conditions set forth in the applicable underwriting agreement. Subject to certain conditions, the underwriters will be obligated to purchase all the securities of the series offered if they purchase any of the securities of that series. We may change from time to time any public offering price and any discounts or concessions the underwriters allow or reallow or pay to dealers. We may use underwriters with whom we have a material relationship. We will name any underwriter involved in the offering and sale of securities, describe any discount or other compensation and describe the nature of any material relationship in any applicable prospectus supplement. Only underwriters we name in the prospectus supplement will be underwriters of the securities offered by that prospectus supplement.

We may have agreements with the agents and underwriters to indemnify them against specified civil liabilities related to offerings under this prospectus, including liabilities under the Securities Act, or contribution with respect to payments that the agents or underwriters may make with respect to these liabilities.

Underwriters, dealers and agents that participate in the distribution of the securities may be underwriters as defined in the Securities Act, and any discounts or commissions they receive from us and any profit on their resale of the securities may be treated as underwriting discounts and commissions under the Securities Act. We will identify in the applicable prospectus supplement any underwriters, dealers or agents and will describe their compensation. We may have agreements with the underwriters, dealers and agents to indemnify them against specified civil liabilities related to offerings under this prospectus, including liabilities under the Securities Act, or contribution with respect to payments that the agents or underwriters may make with respect to these liabilities. Underwriters, dealers and agents may engage in transactions with or perform services for us in the ordinary course of their businesses.

Trading Markets and Listing of Securities

Unless otherwise specified in the applicable prospectus supplement, each class or series of securities will be a new issue with no established trading market, other than our common stock, which is currently listed on the Nasdaq. We may elect to list or qualify for trading any other class or series of securities on any securities exchange or other market, but we are not obligated to do so. It is possible that one or more underwriters may make a market in a class or series of securities, but the underwriters will not be obligated to do so and may discontinue any market making at any time without notice. We cannot give any assurance as to the liquidity of the trading market for any of the securities.

Stabilization Activities

Any underwriter may engage in overallotment, stabilizing transactions, short covering transactions and penalty bids in accordance with Regulation M under the Exchange Act of 1934, as amended, or the Exchange Act. Overallotment involves sales in excess of the offering size, which create a short position. Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum. Short covering transactions involve purchases of the securities in the open market after the distribution is completed to cover short positions. Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the securities originally sold by the dealer are purchased in a covering transaction to cover short positions. Those activities may cause the price of the securities to be higher than it would otherwise be. If commenced, the underwriters may discontinue any of these activities at any time.

Passive Market Making

Any underwriter who is a qualified market maker on the Nasdaq may engage in passive market making transactions in securities listed on the Nasdaq in accordance with Rule 103 of Regulation M, during the business day prior to the pricing of the offering, before the commencement of offers or sales of the securities. A passive market maker must comply with applicable volume and price limitations and must be identified as a passive market maker. In general, a passive market maker must display its bid at a price not in excess of the highest independent bid for such security. If all independent bids are lowered below the passive market maker’s bid, however, the passive market maker’s bid must then be lowered when certain purchase limits are exceeded.

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 14. Other Expenses of Issuance and Distribution.

The following table sets forth an estimate of the fees and expenses relating to the issuance and distribution of the securities being registered hereby, other than underwriting discounts and commissions. All of such fees and expenses, except for the SEC Registration Fee and the FINRA filing fee, are estimated:

Item 15. Indemnification of Officers and Directors.

Section 317 of the California Corporations Code permits indemnification of directors, officers, employees and other agents of corporations under certain conditions and subject to certain limitations. In addition, Section 204(a)(10) of the California Corporations Code permits a corporation to provide, in its articles of incorporation, that directors shall not have liability to the corporation or its shareholders for monetary damages for breach of fiduciary duty, subject to certain prescribed exceptions. Article Five of the Registrant’s Articles of Incorporation contains provisions for the indemnification of directors, officers, employees and other agents within the limitations permitted by Section 317 and for the limitation on the personal liability of directors permitted by Section 204(b)(10), subject to the exceptions required thereby.

Under Article VI of the Registrant’s Bylaws, any person who is or was one of the Registrant’s directors or officers, employees, or other agents, or is or was serving at the Registrant’s request as a director, officer, employee, or agent of another foreign or domestic corporation, partnership, joint venture, trust, or other enterprise, will be considered an “agent” entitled to indemnification against expenses arising under certain proceedings. To the maximum extent permitted by the California Corporations Code, the Registrant will indemnify any person who was or is a party, or is threatened to be made a party, to any proceeding (other than an action by or in the right of the Registrant) by reason of the fact that the person is or was an agent of the Registrant, against expenses, judgments, fines, settlements, and other amounts actually and reasonably incurred in connection with the proceeding if that person acted in good faith and in a manner that person reasonably believed to be in the best interests of the Registrant and, in the case of a criminal proceeding, had no reasonable cause to believe his conduct of was unlawful. The termination of any proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent shall not, of itself, create a presumption that the agent did not act in good faith and in a manner which agent reasonably believed to be in the best interests of the Registrant or that the agent had reasonable cause to believe that his conduct was unlawful.

The Registrant will also indemnify any agent who was or is a party or is threatened to be made a party, to any threatened, pending or completed action by or in the right of the Registrant to procure a judgment in its favor by reason of the fact that person is or was an agent of the Registrant , against expenses actually and reasonably incurred by the agent in connection with the defense or settlement of that action if the agent acted in good faith, in a manner that the agent believed to be in the best interests of the Registrant and with such care, including reasonable inquiry, as an ordinarily prudent person in a like position would use under similar circumstances. No indemnification shall be made:

To the extent that an agent of the Registrant is successful on the merits in defense of any proceeding for which the agent is entitled to indemnification under the Registrant’s Bylaws, the agent will be indemnified against expenses of the defense actually and reasonably incurred. Except as with respect to a successful defense on the merits in a proceeding, indemnification will be provided under the Registrant’s Bylaws only if authorized in the specific case on a determination that indemnification of the agent is proper in the circumstances because the agent has met the applicable standard of conduct set forth in the Registrant’s Bylaws, by:

Expenses incurred in defending any proceeding may be advanced by the Registrant before the final disposition of the proceeding on receipt of an undertaking by or on behalf of the agent to repay the amount of the advance unless it shall be determined ultimately that the agent is entitled to be indemnified as authorized in the Registrant’s Bylaws.

The Registrant will not provide indemnification or advance expenses on behalf of an agent in any circumstance where it appears:

Further, the Registrant maintains directors’ and officers’ liability insurance coverage.

The foregoing summaries are necessarily subject to the complete text of the California Corporations Code and the Registrant’s Articles of Incorporation, Bylaws, and Indemnification Agreements.

Item 16. Exhibits

* To be filed by amendment or incorporated by reference in connection with the offering of the offered securities.

** Filed herewith.

Item 17. Undertakings.

(a) The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

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

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

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

(4) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

(A) each prospectus filed pursuant to Rule 424(b)(3) as part of a registration statement as of the date the filed prospectus was deemed part of and included in the registration statement.

(B) each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(5) That, for purposes of determining any liability under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

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

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

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

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

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

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