6,133,414 Shares of Common Stock

6,645,354 Shares of Common Stock Issuable Upon Exercise of Warrants

This prospectus relates to the resale by the selling stockholders named herein, including their transferees, assigns, pledgees or donees, or their respective successors, of up to (i) 6,133,414 shares (the “Shares”) of our common stock, par value $0.0001 per share (which we refer to as our common stock), (ii) 6,133,414 shares (the “Warrant Shares”) of our common stock issuable upon the exercise of warrants (the “Warrants”) held by certain of the selling stockholders and (iii) 511,940 shares (the “PA Warrant Shares”) of our common stock issuable upon the exercise of placement agent warrants (the “PA Warrants”) held by certain of the selling stockholders. The Shares, Warrants, and PA Warrants were issued by us in a private placement which closed on January 26, 2024 (the “January 2024 Private Placement”). The selling stockholders listed (which includes certain of our officers and directors) herein were the investors in the January 2024 Private Placement or are persons associated with the placement agent for the January 2024 Private Placement. For information about the selling stockholders, see “Selling Stockholders.”

We are not selling any securities under this prospectus and will not receive any of the proceeds from the sale of common stock by the selling stockholder, although we may receive funds upon the future the exercise of Warrants and PA Warrants held by certain of the selling stockholders, if and when exercised for cash. The selling stockholders may sell Shares, Warrant Shares and PA Warrant Shares (which we sometimes refer to herein collectively as the Selling Stockholder Shares) from time to time in the principal markets on which the common stock is quoted at the prevailing market price, at prices related to prevailing market prices or in negotiated transactions. The selling stockholders may sell the Selling Stockholder Shares to or through underwriters, broker-dealers or agents, who may receive compensation in the form of discounts, concessions or commissions from the selling stockholders, the purchasers of the Selling Stockholder Shares, or both. We are registering the offer and sale of the Selling Stockholder Shares pursuant to certain registration rights granted to the selling stockholders. The timing and amount of any sale of Selling Stockholder Shares is within the sole discretion of the selling stockholders. We do not know when or in what amount of Selling Stockholder Shares the selling stockholders may offer for sale. We will pay the expenses of registering the Selling Stockholder Shares, including legal and accounting fees. All selling and other expenses incurred by the selling stockholders will be borne by the selling stockholders. See “Plan of Distribution” for additional information.

Our common stock is listed on The Nasdaq Capital Market under the symbol “RNXT.” On April 18, 2024, the last reported sale price of our common stock on The Nasdaq Capital Market was $1.22 per share.

The purchase of the common stock offered through this prospectus is speculative and involves a high degree of risk. You should carefully consider the risk factors beginning on page 4 of this prospectus before purchasing any of the securities offered by this prospectus.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus, any accompanying prospectus supplement and the information incorporated by reference herein contain forward-looking statements. All statements other than statements of historical facts contained in this prospectus and the information incorporated by reference herein, including statements regarding our future results of operations and financial position, business strategy, product candidates, planned preclinical studies and clinical trials, results of clinical trials, research and development costs, regulatory approvals, timing and likelihood of success, as well as plans and objectives of management for future operations, are forward-looking statements. These statements involve known and unknown risks, uncertainties and other important factors that are in some cases beyond our control and may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. In some cases, you can identify forward-looking statements by terms such as “may,” “will,” “should,” “would,” “expect,” “plan,” “anticipate,” “could,” “intend,” “target,” “project,” “believe,” “estimate,” “predict,” “potential,” or “continue” or the negative of these terms or other similar expressions. Forward-looking statements contained in this prospectus and the documents incorporated by reference herein include, but are not limited to, statements about:

We have based these forward-looking statements largely on our current expectations and projections about our business, the industry in which we operate and financial trends that we believe may affect our business, financial condition, results of operations and prospects, and these forward-looking statements are not guarantees of future performance or development. These forward-looking statements speak only as of the date of this prospectus and are subject to a number of risks, uncertainties and assumptions described in the section titled “Risk Factors” and elsewhere in this prospectus, each accompanying prospectus supplement, and the information incorporated by reference herein and therein. Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified, you should not rely on these forward-looking statements as predictions of future events. The events and circumstances reflected in our forward-looking statements may not be achieved or occur and actual results could differ materially from those projected in the forward-looking statements. Except as required by applicable law, we do not plan to publicly update or revise any forward-looking statements contained herein until after we distribute this prospectus, whether as a result of any new information, future events or otherwise.

In addition, statements that “we believe” and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based upon information available to us as of the date of this prospectus, and while we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain, and you are cautioned not to unduly rely upon these statements.

RISK FACTORS

Investing in our securities is speculative and involves a high degree of risk. Before making a decision to invest in our securities, in addition to carefully considering the Risk Factors noted below and the other information contained in this prospectus and incorporated by reference herein, you should carefully consider the risks described under the caption “Risk Factors” contained in our Annual Report on Form 10-K for our fiscal year ended December 31, 2023 and in our other filings with the Securities and Exchange Commission, as well as any amendments thereto, which are incorporated by reference into this prospectus in their entirety. See “Where You Can Find More Information” and “Incorporation of Certain Information by Reference.”

Risks Relating to this Offering

If you purchase the common stock being offered in this offering, you may experience immediate dilution as a result of this offering.

Since the price per share of our common stock being offered may be substantially higher than the net tangible book value per share of our common stock, you may suffer immediate and substantial dilution in the net tangible book value of the common stock you purchase in this offering.

You may experience future dilution as a result of future equity offerings.

In order to raise additional capital, we may in the future offer additional shares of our common stock or other securities convertible into or exchangeable for our common stock that could result in further dilution to the investor purchasing our common stock in this offering or result in downward pressure on the price of our common stock. We may sell shares of our common stock or other securities in any other offering at prices that are higher or lower than the prices paid by the investor in this offering, and the investor purchasing shares or other securities in the future could have rights superior to existing stockholders. Moreover, to the extent that we issue options or warrants to purchase, or securities convertible into or exchangeable for, shares of our common stock in the future and those options, warrants or other securities are exercised, converted or exchanged, stockholders may experience further dilution.

The trading price of our common stock has been, and is likely to continue to be highly volatile and could be subject to wide fluctuations in response to various factors, some of which are beyond our control.

Our stock price is volatile. During the period from April 15, 2023 to April 15, 2024, the closing price of our common stock ranged from a high of $3.21 per share to a low of $0.60 per share. The stock market in general and the market for smaller pharmaceutical and biotechnology companies in particular have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. As a result of this volatility, you may not be able to sell your common stock at or above the public offering price and you may lose some or all of your investment.

We issued a large number of shares of common stock and warrants to purchase common stock in connection with our 2024 financing activities.  Substantial future sales of such shares of our common stock could cause the market price of our common stock to decline or have other adverse effects on our Company.

In connection with our private placement financing activities in the first few months of 2024, we issued a large number of shares and warrants to purchase common stock. We are obligated to register such shares and shares underlying warrants (totaling an aggregate of approximately 13 million shares of common stock and approximately 20 million shares of common stock underlying warrants) for public resale. While registered, these shares will be freely tradable. Sales of a substantial number of these shares in the public market, or the perception that these sales might occur, could depress the market price of our common stock or cause such market price to decline significantly. Such sales or the perception that such sales might occur could also impair our ability to raise capital through the sale of additional equity securities. We are unable to predict with any certainty the effect that such sales, or the perception that such sales may occur, may have on the prevailing market price of our shares or other adverse impacts this situation could have on our company.

Risks Relating to Our Business

We will need to raise substantial additional capital to develop and commercialize RenovoGem, and our failure to obtain funding when needed may force us to delay, reduce or eliminate our product development programs or collaboration efforts. If we do not obtain adequate and timely funding, we may not be able to continue as a going concern.

We had cash, cash equivalents and short-term marketable securities of $1.2 million as of December 31, 2023. Due to our recurring operating losses and the expectation that we will continue to incur net losses in the future, we have recently raised, and will be required in the future to raise, additional capital to complete the development and commercialization of our product candidates. We have historically financed our operations primarily through private sales of our equity, debt financing and the sale of common stock and warrants in our initial public offering, or IPO. To raise additional capital, we may seek to sell additional equity and/or debt securities, obtain a credit facility or other loan or enter into collaborations, licenses or other similar arrangements, which we may not be able to do on favorable terms, or at all. For example, we have filed an omnibus shelf registration statement on Form S-3 that provides for aggregate offerings of up to $50.0 million of our securities subject to various limitations, including limited sales in any twelve-month period while we are subject to the “baby-shelf” rules. Our ability to obtain additional financing will be subject to a number of factors, including market conditions, fluctuations in interest rates, our operating performance and investor sentiment. If we are unable to raise additional capital when required or on acceptable terms, we may have to significantly delay, scale back or discontinue the development and/or commercialization of our product candidates, restrict or cease our operations or obtain funds by entering into agreements on unfavorable terms. Failure to obtain additional capital on acceptable terms, or at all, would result in a material and adverse impact on our operations. As a result, there is substantial doubt about our ability to continue as a going concern.

Our financial statements as of December 31, 2023 have been prepared on a going concern basis and do not include any adjustments that may result from the outcome of this uncertainty. If we fail to raise additional working capital, or do so on commercially unfavorable terms, it would materially and adversely affect our business, prospects, financial condition and results of operations, and we may be unable to continue as a going concern. As a result, there is substantial doubt about our ability to continue as a going concern. If we seek additional financing to fund our business activities in the future and there remains substantial doubt about our ability to continue as a going concern, investors or other financing sources may be unwilling to provide additional funding to us on commercially reasonable terms, if at all. If we are unable to continue as a going concern, we might have to liquidate our assets and the value we receive for our assets in liquidation or dissolution could be significantly lower than the values reflected in our financial statements, and our shareholders may lose their entire investment in our common stock.

USE OF PROCEEDS

We will not receive any proceeds from the sale of the Selling Stockholder Shares by the selling stockholders. However, we may receive proceeds from the exercise of the Warrants and PA Warrants by the selling stockholders to the extent they are exercised for cash. We estimate that the maximum proceeds that we may receive from the exercise of the Warrants and PA Warrants, assuming all the Warrants are exercised for cash at their applicable exercise prices of either $1.22 or $0.99, will be approximately $6.6 million. We do not know, however, whether any of the Warrants or PA Warrants will be exercised or, if any of the Warrants or PA Warrants are exercised, when they will be exercised. It is possible that the Warrants and PA Warrants will expire and never be exercised. There are circumstances under which the Warrants and the PA Warrants may be exercised on a cashless basis. In these circumstances, even if the Warrants and the PA Warrants are exercised, we may not receive any proceeds, or the proceeds that we do receive may be significantly less than what we might expect.

We will retain broad discretion over the use of the net proceeds to us from the exercise of the Warrants and the PA Warrants. Unless otherwise provided in the applicable prospectus supplement, we currently expect to use the aggregate net proceeds from the exercise of the Warrants and PA Warrants for general corporate purposes, including working capital. We may also use a portion of the net proceeds to acquire, license or invest in complementary products, technologies or businesses; however, we currently have no agreements or commitments to complete any such transaction. The expected use of net proceeds from the exercise of the Warrants and the PA Warrants represents our current intentions based on our present plans and business conditions. We cannot specify with certainty all of the particular uses for the net proceeds to be received from the exercise of the Warrants and PA Warrants. Pending these uses, we plan to invest the net proceeds of this offering in short- and intermediate-term, interest-bearing obligations, investment-grade instruments, certificates of deposit or direct or guaranteed obligations of the U.S. government. The actual allocation of proceeds realized from the exercise of the Warrants and the PA Warrants will depend upon the amount and timing of such exercises, our operating revenues and cash position at such time and our working capital requirements.

The selling stockholders will pay any expenses incurred by the selling stockholders for brokerage, accounting, tax or legal services or any other expenses incurred by the selling stockholders in disposing of their shares of common stock. We will bear all other costs, fees and expenses incurred in effecting the registration of the Selling Stockholder Shares covered by this prospectus, including, without limitation, all registration fees and fees and expenses of our counsel and our accountants.

SELLING STOCKHOLDERS

The shares of common stock being offered by the selling stockholders listed below were issued in, or are underlying the Warrants and PA Warrants issued in connection with, the January 2024 Private Placement. Other than the relationships as purchasers under the Subscription Agreements (as defined below) and as otherwise described herein, to our knowledge, no material relationships exist between any of the selling stockholders and us nor have any such material relationships existed within the past three years.

As used herein, the term “selling stockholders” means the selling stockholders listed below and such holders’ donees, pledgees, transferees, or other successors-in-interest selling shares of common stock or warrant shares received after the date of this prospectus from a selling stockholder as a gift, pledge, partnership distribution or other transfer.

Summary of January 2024 Private Placement

On January 26, 2024, we entered into a series of subscription agreements (the “Subscription Agreements”), in connection with the January 2024 Private Placement to 92 accredited investors (who are among the selling stockholders hereunder), which private placement was also closed on January 26, 2024. In connection with the January 2024 Private Placement, we raised aggregate gross proceeds of $6,111,695.

In connection with the January 2024 Private Placement, we sold to the selling stockholder who were investors in the placement an aggregate of 6,133,414 shares of our common stock (the “Shares”) and common stock purchase warrants (the “Investor Warrants”) to purchase an aggregate of up to 6,133,414 shares of common stock (the “Investor Warrant Shares” and collectively with the Shares and the Investor Warrants, the “Investor Securities”).

Investors paid a purchase price of $0.99 for each Share and related Investor Warrant. The exercise price of the Investor Warrants is also $0.99 per share. The five investors who are either officers, directors, employees or consultants to our company paid a purchase price of $1.22 for each Share and related Investor Warrant. The exercise price of these Investor Warrants is also $1.22 per share.

Pursuant to the Subscription Agreements, we agreed to use our commercially reasonable efforts to file a registration statement for the resale of the Shares and the Investor Warrant Shares, within 30 days after the closing of the January 2024 Private Placement and to cause the SEC to declare such registration statement effective as promptly as possible thereafter. We have filed the registration statement of which this prospectus is a part to satisfy this obligation.

In connection with the January 2024 Private Placement, on November 14, 2023,we entered into a placement agent agreement (the “Placement Agent Agreement”) with Paulson Investment Company, LLC (the “Placement Agent”), pursuant to which the Placement Agent agreed to act as our placement agent in connection with the January 2024 Private Placement. Under the terms of the Placement Agent Agreement, we paid selling commissions of 12% of gross offering proceeds from the sale of the Shares and Investor Warrants in the January 2024 Private Placement; provided, however, that selling commissions of 3% of gross offering proceeds were paid with respect to all subscriptions received from Investors who were introduced by us. Total selling commissions paid by us to the Placement Agent were $508,043. We also paid the Placement Agent $25,000 as a non-accountable expense fee. In addition, as additional compensation, we issued PA Warrants to the Placement Agent and its designees to purchase an aggregate of up to 511,940 PA Warrant Shares at an exercise price of $0.99 per share and also agreed to include the PA Warrant Shares for resale in the registration statement of which this prospectus forms a part, along with the Shares and the Investor Warrant Shares.

Selling Stockholders Table

The table below lists the selling stockholders and other information regarding the beneficial ownership of the shares of common stock by each of the selling stockholders. The table below sets forth information as of the date of this prospectus, to our knowledge, about the beneficial ownership of our common stock by the selling stockholders both before and immediately after this offering. Because the selling stockholders may sell, transfer, or otherwise dispose of all, some, or none of their shares of common stock, we cannot determine the number of such shares that will be sold, transferred or otherwise disposed of by the selling stockholders, or the amount or percentage of shares of our common stock that will be held by the selling stockholders upon termination of any particular offering. See “Plan of Distribution.” For purposes of the table below, we assume that the selling stockholders will sell all of their shares of common stock.

PLAN OF DISTRIBUTION

We are registering the Selling Stockholder Shares on behalf of the selling stockholders to permit the resale of such shares by the selling stockholders from time to time after the date of this prospectus. The Selling Stockholder Shares were purchased or are acquirable by the selling stockholders, who participated in the January 2024 Private Placement. We will not receive any of the proceeds from the sale by the selling stockholders of the shares of common stock. We will bear all fees and expenses incident to our obligation to register the shares of common stock.

The selling stockholders, which may include donees, pledgees, transferees or other successors-in-interest selling shares of common stock or interests in shares of common stock received after the date of this prospectus from a selling stockholders as a gift, pledge, partnership distribution or other transfer, may sell all or a portion of the shares of common stock beneficially owned by them and offered hereby from time to time on any stock exchange, market or trading facility on which the shares are traded or in private transactions.

A selling stockholder may use any one or more of the following methods when disposing of shares or interests therein:

The selling stockholders may, from time to time, pledge or grant a security interest in some or all of the shares of common stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of common stock, from time to time, under this prospectus, or under an amendment to this prospectus under Rule 424(b) or other applicable provision of the Securities Act amending the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus. The selling stockholders also may transfer the shares of common stock in other circumstances, in which case the pledgees, transferees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.

The selling stockholders also may resell all or a portion of the shares in open market transactions in reliance upon Rule 144 under the Securities Act, as permitted by that rule, or Section 4(a)(1) under the Securities Act, if available, rather than under this prospectus; provided that they meet the criteria and conform to the requirements of those provisions.

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

The aggregate proceeds to the selling stockholders from the sale of the common stock offered by them will be the purchase price of the common stock less discounts or commissions, if any. The selling stockholders reserve the right to accept and, together with its agents from time to time, to reject, in whole or in part, any proposed purchase of common stock to be made directly or through agents. We will not receive any of the proceeds from this offering.

The selling stockholders and any underwriters, broker-dealers or agents that participate in the sale of the common stock or interests therein may be “underwriters” within the meaning of Section 2(11) of the Securities Act. Any discounts, commissions, concessions or profit they earn on any resale of the shares may be underwriting discounts and commissions under the Securities Act. If the selling stockholders is an “underwriter” within the meaning of Section 2(11) of the Securities Act, it will be subject to the prospectus delivery requirements of the Securities Act.

To the extent required, the shares of our common stock to be sold, the name of the selling stockholder, the respective purchase prices and public offering prices, the names of any agents, dealer or underwriter, and any applicable commissions or discounts with respect to a particular offer will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement that includes this prospectus.

If underwriters are used in the sale, the shares of common stock will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. In connection with any such underwritten sale of shares of common stock, underwriters may receive compensation from the selling stockholder, for whom they may act as agents, in the form of discounts, concessions or commissions. If the selling stockholder uses an underwriter or underwriters to effectuate the sale of shares of common stock, we and/or it will execute an underwriting agreement with those underwriters at the time of sale of those shares of common stock.

To the extent required by law, the names of the underwriters will be set forth in a prospectus supplement or, if appropriate, a post-effective amendment to the registration statement that includes the prospectus supplement and the accompanying prospectus used by the underwriters to sell those securities. The obligations of the underwriters to purchase those shares of common stock will be subject to certain conditions precedent, and unless otherwise specified in a prospectus supplement, the underwriters will be obligated to purchase all the shares of common stock offered by such prospectus supplement if any of such shares of common stock are purchased. Any public offering price and any discounts or concessions allowed or re-allowed or paid to dealers may be changed from time to time.

The selling stockholders may indemnify any broker-dealer that participates in transactions involving the sale of the shares against certain liabilities, including liabilities arising under the Securities Act.

Item 14. Other Expenses of Issuance and Distribution

The following is an estimate (other than the SEC registration fee) of the expenses (all of which are to be paid by the registrant) that we may incur in connection with the securities being registered hereby.

Item 15. Indemnification of Directors and Officers

Section 145 of the Delaware General Corporation Law authorizes a corporation’s board of directors to grant, and authorizes a court to award, indemnity to officers, directors, and other corporate agents, provided that the person acted in good faith and in a manner the person reasonably believed to be in the corporation’s best interests, and, with respect to any criminal action, had no reasonable cause to believe the person’s actions were unlawful. A similar standard is applicable in the case of derivative actions, except that indemnification extends only to expenses, including attorneys’ fees, incurred in connection with the defense or settlement of such action and the statute requires court approval before there can be any indemnification where the person seeking indemnification has been found liable to the corporation. The Delaware General Corporation Law further provides that the indemnification permitted thereunder shall not be deemed exclusive of any other rights to which the directors and officers may be entitled under the corporation’s bylaws, any agreement, a vote of stockholders or otherwise.

The registrant’s Sixth Amended and Restated Certificate of Incorporation (the “Certificate of Incorporation”) and Amended and Restated Bylaws (the “Bylaws”) provide for indemnification of directors and officers to the fullest extent permitted by law, including payment of expenses in advance of resolution of any such matter.

Section 102(b)(7) of the Delaware General Corporation Law permits a corporation to provide in its certificate of incorporation that a director or officer of the corporation shall not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director or officer, except (1) for any breach of the director’s or officer’s duty of loyalty to the corporation or its stockholders, (2) for acts or omissions by a director or officer not in good faith or which involve intentional misconduct or a knowing violation of law, (3) for payments of unlawful dividends or unlawful stock repurchases or redemptions made to a director,(4) for any transaction from which the director or officer derived an improper personal benefit or (5) an officer in any action by or in the right of the corporation. The Amended and Restated Certificate of Incorporation of the registrant provides that the registrant’s directors shall not be personally liable to it or its stockholders for monetary damages for breach of fiduciary duty as a director and that if the Delaware General Corporation Law is amended to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of the registrant’s directors shall be eliminated or limited to the fullest extent permitted by the Delaware General Corporation Law, as so amended.

Section 174 of the Delaware General Corporation Law provides, among other things, that a director who willfully or negligently approves of an unlawful payment of dividends or an unlawful stock purchase or redemption may be held liable for such actions. A director who was either absent when the unlawful actions were approved, or dissented at the time, may avoid liability by causing his or her dissent to such actions to be entered in the books containing minutes of the meetings of the board of directors at the time such action occurred or immediately after such absent director receives notice of the unlawful acts.

Further, as permitted by the Delaware General Corporation Law, the registrant has entered into separate indemnification agreements with each of its directors and officers that may be broader than the specific indemnification provisions contained in the Delaware General Corporation Law. Each indemnification agreement provides, among other things, for indemnification to the fullest extent permitted by law and the Certificate of Incorporation and Bylaws against any and all expenses, judgments, fines, penalties and amounts paid in settlement of any claim. The indemnification agreements provide for the advancement or payment of all expenses to the indemnitee and for reimbursement to the registrant if it is found that such indemnitee is not entitled to such indemnification under applicable law and the Certificate of Incorporation and Bylaws.

The registrant has obtained and maintains standard policies of insurance under which coverage is provided (a) to its directors and officers against loss(es) rising from claims made by reason of breach of duty or other wrongful act, and (b) to it with respect to payments that it may make to such officers and directors pursuant to the above indemnification provision or otherwise as a matter of law. The coverage provided by these policies may apply whether or not the registrant would have the power to indemnify such person against such liability under the provisions of the Delaware General Corporation Law.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling the registrant under the foregoing provisions, the registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.

See also the undertakings set out in response to Item 17 herein.

Item 16. Exhibits

(a) Exhibits

A list of exhibits filed with this registration statement on Form S-3 is set forth on the Exhibit Index and is incorporated herein by reference.

Item 17. Undertakings

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:

a. To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933, as amended;

b. To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

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

Provided, however, that paragraphs (1)(a), (b) and (c) of this section do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC 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 by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

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, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) 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.

6) 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 SEC such indemnification is against public policy as expressed in the Securities 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 Securities Act and will be governed by the final adjudication of such issue.
