ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement that we filed with the Securities and Exchange Commission, or SEC, using a “shelf” registration process, as a “well-known seasoned issuer” as defined in Rule 405 under the Securities Act of 1933, as amended (the “Securities Act”). Under this shelf registration process, we and any selling stockholders to be named in a prospectus supplement, or an amendment to the registration statement of which this prospectus is a part, may, from time to time, offer and sell any combination of the securities described in this prospectus in one or more offerings. This prospectus describes the general manner in which our securities may be offered by this prospectus. Each time we sell securities, we will provide a prospectus supplement that will contain specific information about the terms of that offering, including the specific amounts, prices and terms of the securities offered or sold. The prospectus supplement may also add, update or change information contained in this prospectus or in documents incorporated by reference in this prospectus. The prospectus supplement that contains specific information about the terms of the securities being offered may also include a discussion of certain U.S. Federal income tax consequences and any risk factors or other special considerations applicable to those securities. To the extent that any statement that we make in a prospectus supplement is inconsistent with statements made in this prospectus or in documents incorporated by reference in this prospectus, you should rely on the information in the prospectus supplement. You should carefully read both this prospectus and any prospectus supplement together with the additional information described under “Where You Can Find More Information” before buying any securities in this offering. Because we are a well-known seasoned issuer, as defined in Rule 405 under the Securities Act, we may add to and offer additional securities including secondary securities, by filing a prospectus supplement or term sheet with the SEC at the time of the offer.

Unless we state otherwise or the context otherwise requires, (i) the terms “Red Cat,” “Red Cat Holdings,” the “Company,” “we,” “our” or “us” in this prospectus refer to Red Cat Holdings, Inc., and (ii) references to “selling stockholder” or “selling stockholders” include donees, pledgees, transferees or other successors-in-interest selling shares of common stock received from any selling stockholders as a gift, pledge, partnership distribution or other transfer after the date of this prospectus.

Neither we, any selling stockholders, nor any agent, underwriter or dealer, have authorized any person to give any information or to make any representation other than those contained or incorporated by reference into this prospectus, any applicable prospectus supplement or any related free writing prospectus prepared by or on behalf of us or to which we have referred you. This prospectus, any applicable supplement to this prospectus or any related free writing prospectus do not constitute an offer by us or the selling stockholders to sell or the solicitation of an offer to buy any securities other than the registered securities to which they relate, nor do this prospectus, any applicable supplement to this prospectus or any related free writing prospectus constitute an offer by us or the selling stockholders to sell or the solicitation of an offer to buy securities in any jurisdiction to any person to whom it is unlawful to make such offer or solicitation in such jurisdiction.

You should not assume that the information contained in this prospectus, any applicable prospectus supplement or any related free writing prospectus is accurate on any date subsequent to the date set forth on the front of such document or that any information we have incorporated by reference is correct on any date subsequent to the date of the document incorporated by reference, even though this prospectus, any applicable prospectus supplement or any related free writing prospectus is delivered, or securities are sold, on a later date.

Our amended and restated articles of incorporation authorizes us to issue up to 500,000,000 shares of common stock. In addition, under our amended and restated articles of incorporation, our board of directors has the authority, without further action by stockholders, to designate up to 10,000,000 shares of preferred stock, par value $0.001 per share, in one or more series and to fix the rights, preferences, privileges, qualifications and restrictions granted to or imposed upon the preferred stock, including dividend rights, conversion rights, voting rights, rights and terms of redemption, liquidation preference and sinking fund terms, any or all of which may be greater than the rights of our common stock. The issuance of preferred stock could adversely affect the voting power of holders of common stock and reduce the likelihood that common stockholders will receive dividend payments and payments upon liquidation. The issuance could also have the effect of decreasing the market price of the common stock. The issuance of preferred stock also could have the effect of delaying, deterring or prevent a change in control of us.

Anti-Takeover Effects of Provisions of Our Amended and Restated Articles of Incorporation, Our Bylaws and Nevada Law

Nevada Anti-Takeover Law

The Nevada Revised Statutes (“NRS”) contain several provisions which may make a hostile take-over or change of control of our Company more difficult to accomplish. They include the following:

Under Nevada law, any one or all of the directors of a corporation may be removed by the holders of not less than two-thirds of the voting power of a corporation’s issued and outstanding stock. All vacancies on the board of directors of a Nevada corporation may be filled by a majority of the remaining directors, though less than a quorum, unless the articles of incorporation provide otherwise. In addition, unless otherwise provided in the articles of incorporation, the board may fill the vacancies for the entire remainder of the term of office of the resigning director or directors. Our Articles of Incorporation do not provide otherwise.

In addition, Nevada law provides that unless otherwise provided in a corporation’s articles of incorporation or bylaws, shareholders do not have the right to call special meetings. Our articles of incorporation and our bylaws do not give shareholders this right. In accordance with Nevada law, we also require advance notice of any shareholder proposals.

Nevada law provides that, unless otherwise prohibited by any bylaws adopted by the shareholders, the board of directors may amend any bylaw, including any bylaw adopted by the shareholders. Pursuant to Nevada law, our articles of incorporation grant the authority to adopt, amend or repeal bylaws exclusively to our directors.

Nevada’s “combinations with interested stockholders” statutes prohibit certain business “combinations” between certain Nevada corporations and any person deemed to be an “interested stockholder” for two years after such person first becomes an “interested stockholder” unless (i) the corporation’s board of directors approves the combination (or the transaction by which such person becomes an “interested stockholder”) in advance, or (ii) the combination is approved by the board of directors and sixty percent of the corporation’s voting power not beneficially owned by the interested stockholder, its affiliates and associates. Furthermore, in the absence of prior approval, certain restrictions may apply even after such two-year period. For purposes of these statutes, an “interested stockholder” is any person who is (x) the beneficial owner, directly or indirectly, of ten percent or more of the voting power of the outstanding voting shares of the corporation, or (y) an affiliate or associate of the corporation and at any time within the two previous years was the beneficial owner, directly or indirectly, of ten percent or more of the voting power of the then outstanding shares of the corporation. Subject to certain timing requirements set forth in the statutes, a corporation may elect not to be governed by these statutes. We have included a provision in our Articles of Incorporation electing not to be governed by the provisions of NRS §78.411 through NRS §78.444, inclusive.

Nevada’s “acquisition of controlling interest” statutes contain provisions governing the acquisition of a controlling interest in certain Nevada corporations. These “control share” laws provide generally that any person who acquires a “controlling interest” in certain Nevada corporations may be denied certain voting rights, unless a majority of the disinterested stockholders of the corporation elects to restore such voting rights. These statutes provide that a person acquires a “controlling interest” whenever a person acquires shares of a subject corporation that, but for the application of these provisions of the NRS, would enable that person to exercise (1) one-fifth or more, but less than one-third, (2) one-third or more, but less than a majority or (3) a majority or more, of all of the voting power of the corporation in the election of directors. Once an acquirer crosses one of these thresholds, shares which it acquired in the transaction taking it over the threshold and within the 90 days immediately preceding the date when the acquiring person acquired or offered to acquire a controlling interest become “control shares” to which the voting restrictions described above apply. Our Articles of Incorporation and Bylaws currently contain no provisions relating to these statutes, and unless our Articles of Incorporation or Bylaws in effect on the tenth day after the acquisition

TABLE OF CONTENTS

•

Before exercising their warrants, holders of warrants will not have any of the rights of holders of the securities purchasable upon such exercise, including, in the case of warrants to purchase common stock or preferred stock, the right to receive dividends, if any, or payments upon our liquidation, dissolution or winding up or to exercise voting rights, if any.

Exercise of Warrants

Each warrant will entitle the holder to purchase the securities or shares of stock at such exercise price that we describe in the applicable prospectus supplement. Unless we otherwise specify in the applicable prospectus supplement, holders of the warrants may exercise the warrants at any time up to the close of business on the expiration date that we set forth in the applicable prospectus supplement. After the close of business on the expiration date, unexercised warrants will become void.

Unless we otherwise specify in the applicable prospectus supplement, holders of the warrants may exercise the warrants by delivering the warrant certificate representing the warrants to be exercised together with specified information and paying the required amount to the warrant agent in immediately available funds, as provided in the applicable prospectus supplement. We will set forth on the reverse side of the warrant certificate and in the applicable prospectus supplement the information that the holder of the warrant will be required to deliver to the warrant agent in connection with the exercise of the warrant.

Upon receipt of the required payment and the warrant or warrant certificate, as applicable, properly completed and duly executed at the corporate trust office of the warrant agent, if any, or any other office indicated in the applicable prospectus supplement, we will issue and deliver the securities purchasable upon such exercise. If fewer than all of the warrants or of the warrants represented by such warrant certificate, as applicable, are exercised, then we will issue a new warrant or warrant certificate, as applicable, for the remaining number 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.

Governing Law

Unless we provide otherwise in the applicable prospectus supplement, the warrants and warrant agreements, and any claim, controversy or dispute arising under or related to the warrants or warrant agreements, will be governed by and construed in accordance with the laws of the State of New York.

Enforceability of Rights by Holders of Warrants

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

Amendments and Supplements to the Warrant Agreements

We may amend or supplement a warrant agreement without the consent of the holders of the applicable warrants to cure ambiguities in the warrant agreement, to cure or correct a defective provision in the warrant agreement, or to provide for other matters under the warrant agreement that we and the warrant agent deem necessary or desirable, so long as, in each case, such amendments or supplements do not materially adversely affect the interests of the holders of the warrants.

Warrant Adjustments

Unless the applicable prospectus supplement states otherwise, the exercise price of, and the number of securities covered by, a warrant to purchase shares of common stock or preferred stock will be adjusted

TABLE OF CONTENTS

proportionately if we subdivide or combine common stock or preferred stock, as applicable. In addition, unless the prospectus supplement states otherwise, if we, without payment:

•

issue capital stock or other securities convertible into or exchangeable for common stock or preferred stock, or any rights to subscribe for, purchase or otherwise acquire either class of capital stock, as a dividend or distribution to holders of our common stock or preferred stock;

•

pay any cash to holders of our common stock or preferred stock other than a cash dividend paid out of our current or retained earnings or other than in accordance with the terms of the preferred stock;

•

issue any evidence of our indebtedness or rights to subscribe for or purchase our indebtedness to holders of our common stock or preferred stock; or

•

issue common stock or preferred stock or additional stock or other securities or property to holders of our common stock or preferred stock by way of spinoff, split-up, reclassification, combination of shares or similar corporate rearrangement,

then the holders of warrants will be entitled to receive upon exercise of the warrants, in addition to the securities otherwise receivable upon exercise of the warrants and without paying any additional consideration, the amount of stock and other securities and property those holders would have been entitled to receive had they held the common stock or preferred stock, as applicable, issuable under the warrants on the dates on which holders of those securities received or became entitled to receive the additional stock and other securities and property.

Except as stated above, the exercise price and number of securities covered by a common stock or preferred stock warrant, and the amounts of other securities or property to be received, if any, upon exercise of those warrants, will not be adjusted or provided for if we issue those securities or any securities convertible into or exchangeable for those securities, or securities carrying the right to purchase those securities or securities convertible into or exchangeable for those securities.

Holders of common stock or preferred stock warrants may have additional rights under the following circumstances:

•

certain reclassifications, capital reorganizations or changes of the common stock or preferred stock, as applicable,

•

certain share exchanges, mergers, or similar transactions involving our company, and which result in changes of common stock or preferred stock, as applicable; or

•

certain sales or dispositions to another entity of all or substantially all of our property and assets.

If one of the above transactions occurs and holders of our common stock or preferred stock are entitled to receive capital stock, securities or other property with respect to or in exchange for their securities, the holders of the common stock or preferred stock warrants then outstanding, as applicable, will be entitled to receive upon exercise of their warrants the kind and amount of shares of capital stock and other securities or property that they would have received upon the applicable transaction if they had exercised their warrants immediately before the transaction.

TABLE OF CONTENTS

PLAN OF DISTRIBUTION

We and/or the selling stockholders may sell our securities in any one or more of the following ways:

•

to or through underwriters, brokers or dealers (acting as agent or principal);

•

broker-dealers may agree with selling stockholders to sell a specified number of shares of common stock at a stipulated price per share;

•

directly to one or more other purchasers;

•

upon the exercise of rights distributed or issued to our security holders;

•

through a block trade in which the broker or dealer engaged to handle the block trade will attempt to sell the securities as agent, but may position and resell a portion of the block as principal to facilitate the transaction;

•

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

•

directly to purchasers, through a specific bidding or auction process, on a negotiated basis or otherwise;

•

through agents on a best-efforts basis;

•

through any other method permitted pursuant to applicable law; or

•

otherwise through a combination of any of the above methods of sale.

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

•

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

•

at market prices prevailing at the time of sale;

•

at prices related to prevailing market prices;

•

at varying prices determined at the time of sale; or

•

at negotiated prices.

In addition, we or the selling stockholders may enter into option, share lending or other types of transactions that require us or the selling stockholders to deliver shares of common stock to an underwriter, broker or dealer, who will then resell or transfer the shares of common stock under this prospectus. We or the selling stockholders may also enter into hedging transactions with respect to our securities. For example, we or the selling stockholders may enter into security lending or repurchase agreements with the underwriters or agents that require us or the selling stockholders to loan or pledge the shares of common stock to an underwriter, broker or dealer, who may sell the loaned shares or, in the event of default, sell the pledged shares. In addition, the selling stockholders may enter into hedging transactions with dealers which may engage in short sales of shares of common stock in the course of hedging the positions they assume with the selling stockholders. The selling stockholders may also sell shares of common stock short and deliver shares of common stock to close out such short position. The selling stockholders may also enter into option or other transactions with dealers that require the delivery by such dealers of shares of common stock, which securities may be resold pursuant to this prospectus or any applicable prospectus supplement.

We or the selling stockholders may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement so indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third party may use securities pledged by or borrowed from us, the selling stockholders or others to settle those sales or to close out any related open borrowings of stock and may use securities received from us or the selling stockholders in settlement of those derivatives to close out any related open borrowings of stock. The third party in such sale transactions will be an underwriter and, if not identified in this prospectus, will be identified in the applicable prospectus supplement (or a post-effective amendment of the registration

TABLE OF CONTENTS

statement of which this prospectus is a part). In addition, we or the selling stockholders may otherwise loan or pledge securities to a financial institution or other third party that in turn may sell the securities short using this prospectus. Such financial institution or other third party may transfer its economic short position to investors in our securities or in connection with a concurrent offering of other securities.

If we or the selling stockholders use any underwriter, the prospectus supplement will name any underwriter involved in the offer and sale of the securities, including the name or names of any selling stockholders, if applicable. If underwriters or dealers are used in the sale, the securities will be acquired by the underwriters or dealers for their own account. The prospectus supplement will also set forth the terms of the offering, including:

•

the purchase price of the securities and the proceeds we or the selling stockholders will receive from the sale of the securities;

•

any underwriting discounts and other items constituting underwriters’ compensation;

•

any public offering or purchase price and any discounts or commissions allowed or re-allowed or paid to dealers;

•

any commissions allowed or paid to agents;

•

any securities exchanges on which the securities may be listed;

•

the method of distribution of the securities;

•

the terms of any agreement, arrangement or understanding entered into with the underwriters, brokers or dealers; and

•

any other information we think is important.

The securities may be offered to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more of such firms. Unless otherwise set forth in the prospectus supplement, the obligations of underwriters or dealers to purchase the securities offered will be subject to certain conditions precedent and the underwriters or dealers will be obligated to purchase all of the offered securities if any are purchased. Any public offering price and any discount or concession allowed or reallowed or paid by underwriters or dealers to other dealers may be changed from time to time.

To our knowledge, there are currently no plans, arrangements or understandings between the selling stockholders and any underwriter, dealer or agent regarding the sale of the shares covered by this prospectus by such selling stockholders. If any selling stockholder notifies us that a material arrangement has been entered into with an underwriter, dealer or other agent for the sale of shares through a block trade, special offering or secondary distribution, we may be required to file a prospectus supplement pursuant to applicable SEC rules promulgated under the Securities Act.

The securities may be sold directly by us or the selling stockholders through agents designated by us from time to time. Any agent involved in the offer or sale of the securities in respect of which this prospectus is delivered will be named in, and any commissions payable by us or the selling stockholders to such agent will be set forth in, the prospectus supplement. Any required prospectus supplement will name any agent involved in the offer or sale of the offered securities and will describe any commissions payable to the agent by the selling stockholders. Unless otherwise indicated in the prospectus supplement, any such agent will be acting on a best-efforts basis for the period of its appointment.

A selling stockholder that is an entity may elect to make a pro-rata in-kind distribution of shares of common stock to its members, partners or stockholders pursuant to the registration statement of which this prospectus forms a part by delivering a prospectus. To the extent that such members, partners or stockholders are not affiliates of ours, such member, partner or stockholder would thereby receive fully tradeable shares of common stock pursuant to the distribution through a registration statement. To the extent that such members, partners or stockholders are affiliates of ours (or to the extent otherwise required by law), we may file a prospectus supplement in order to permit such members, partners or stockholders to use the prospectus to resell shares of common stock acquired in the distribution.

TABLE OF CONTENTS

Offers to purchase the securities offered by this prospectus may be solicited, and sales of the securities may be made by us or the selling stockholders directly to institutional investors or others, who may be deemed to be underwriters within the meaning of the Securities Act with respect to any resale of the securities. The terms of any offer made in this manner will be included in the prospectus supplement relating to the offer. If indicated in the applicable prospectus supplement, underwriters, dealers or agents will be authorized to solicit offers by certain institutional investors to purchase securities from us or the selling stockholders pursuant to contracts providing for payment and delivery at a future date on the terms set forth in the applicable prospectus supplement.

The selling stockholders and any broker-dealers, agents or underwriters that are involved in an arrangement to sell any of the offered securities may, under certain circumstances, be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such agents, underwriters or dealers and any profit on the resale of shares of common stock purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Except as indicated in the applicable prospectus supplement, any purchasers will pay all discounts, concessions, commissions and similar selling expenses, if any, that can be attributed to the sale of the shares of such common stock.

Some of the underwriters, dealers or agents used by us or the selling stockholders in any offering of securities under this prospectus may be customers of, engage in transactions with, and perform services for us or the selling stockholders or our respective affiliates in the ordinary course of business. Underwriters, dealers, agents and other persons may be entitled under agreements which may be entered into with us or the selling stockholders to indemnification against and contribution toward certain civil liabilities, including liabilities under the Securities Act, and to be reimbursed by us or the selling stockholders for certain expenses, by us or the selling stockholders.

Any securities initially sold outside the U.S. may be resold in the U.S. through underwriters, dealers or otherwise.

The anticipated date of delivery of the securities offered by this prospectus will be described in the applicable prospectus supplement relating to the offering.

In compliance with the guidelines of the Financial Industry Regulatory Authority, or FINRA, the aggregate maximum discount, commission, agency fees or other items constituting underwriting compensation to be received by any FINRA member or independent broker-dealer will not exceed such amounts as is determined to be unfair or unreasonable under applicable FINRA rules.

No FINRA member may participate in any offering of securities made under this prospectus if such member has a conflict of interest under FINRA Rule 5121 unless a qualified independent underwriter has participated in the offering, or the offering otherwise complies with FINRA Rule 5121.

To comply with the securities laws of some states, if applicable, the securities that may be offered pursuant to this prospectus may be sold in these jurisdictions only through registered or licensed brokers or dealers. In addition, in some states the securities may not be sold unless they have been registered or qualified for sale or an exemption from registration or qualification requirements is available and is complied with.

All securities we or the selling stockholders may offer pursuant to this prospectus, other than common stock, will be new issues of securities with no established trading market. Any underwriters may make a market in these securities but will not be obligated to do so and may discontinue any market making at any time without notice. We cannot guarantee the liquidity of the trading markets for any securities.

Any underwriter may engage in over-allotment, stabilizing transactions, short-covering transactions and penalty bids in accordance with Regulation M under the Exchange Act. Over-allotment 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 price. Syndicate-covering or other short-covering transactions involve purchases of the securities, either through exercise of the over-allotment option or 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

TABLE OF CONTENTS

sold by the dealer are purchased in a stabilizing or 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 the activities at any time.

Any underwriters or agents that are qualified market makers may engage in passive market making transactions in the common stock in accordance with Regulation M under the Exchange Act, during the business day prior to the pricing of the offering, before the commencement of offers or sales of common stock. Passive market makers must comply with applicable volume and price limitations and must be identified as passive market makers. 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. Passive market making may stabilize the market price of the securities at a level above that which might otherwise prevail in the open market and, if commenced, may be discontinued at any time.

Under certain circumstances, Chapter 78 of the NRS also provides for mandatory and discretionary indemnification, as applicable, of any person who is a director, officer, employee or agent of the Company.

Nevada law also provides that we must indemnify any person who is a director, officer, employee or agent of the Company, to the extent that the person is successful on the merits or otherwise in the defense of any threatened, pending or completed action, suit or proceeding brought against such person because such person is or was a director, officer, employee or agent of the Company, against expenses actually and reasonably incurred by the person in connection with defending the action, including, without limitation, attorney’s fees.

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

(i) To include any prospectus required by section 10(a)(3) of the Securities Act;

(ii) 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 Commission 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.

(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) [Reserved]

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

(i) 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

(ii) 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 of 1933 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;

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

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

(c) Insofar as indemnification for liabilities arising under the Securities Act 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.
