TABLE OF CONTENTS

ABOUT THIS PROSPECTUS

This prospectus is part of an “automatic shelf” registration statement that we filed with the Securities and Exchange Commission (the “SEC”) as a “well-known seasoned issuer” as defined in Rule 405 under the Securities Act of 1933, as amended (the “Securities Act”), using a “shelf” registration process. Under this process, we or a selling securityholder may offer and sell from time to time any combination of the securities described in this prospectus. This prospectus only provides you with a general description of the securities that we or a selling securityholder may offer. Each time we or a selling securityholder sell securities, we or a selling securityholder will provide a supplement to this prospectus that contains specific information about the terms of that offering, including the specific amounts, prices and terms of the securities offered. The prospectus supplement may also add, update or change information contained in this prospectus. You should carefully read both this prospectus, any accompanying prospectus supplement and any free writing prospectus prepared by or on behalf of us, together with the additional information described under the heading “Where You Can Find More Information.”

Neither we nor any selling securityholder has authorized anyone to provide you with any information other than that contained in or incorporated by reference into this prospectus, any accompanying prospectus supplement and any free writing prospectus prepared by or on behalf of us or any selling securityholder. Neither we nor any selling securityholder takes any responsibility for, and can provide no assurance as to the reliability of, any other information that others may give you. Neither we nor any selling securityholder is making offers to sell the securities in any jurisdiction in which an offer or solicitation is not authorized or in which the person making such offer or solicitation is not qualified to do so or to anyone to whom it is unlawful to make an offer or solicitation.

You should assume that the information appearing in this prospectus, any prospectus supplement or any document incorporated by reference is accurate only as of the date of the applicable documents, regardless of the time of delivery of this prospectus or any sale of securities.

Bitfarms Ltd. (“Bitfarms”) was founded in 2017 and was publicly traded on the Nasdaq and TSX under the ticker symbol “BITF”. On April 1, 2026, Bitfarms completed a U.S. redomiciliation, pursuant to which shareholders of Bitfarms exchanged their shares of Bitfarms for shares of a newly formed public company incorporated in the State of Delaware, Keel Infrastructure Corp.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus and any accompanying prospectus supplement and any documents incorporated by reference contain statements that are “forward-looking” within the meaning of the Private Securities Litigation Reform Act of 1995.

Forward-looking statements can often be identified by the use of forward-looking language such as “may,” “should,” “believes,” “expects,” “anticipates,” “plans,” “estimates,” “intends,” “projects,” “goals,” “objectives,” or other similar expressions. Our actual results, performance or achievements could be materially different from the results expressed in, or implied by, forward-looking statements.

By their very nature, forward-looking statements involve known and unknown risks, uncertainties and other factors that may cause actual results or events to differ materially from those anticipated in such forward-looking statements, including but not limited to the risks described in this prospectus, any accompanying prospectus supplement and any documents incorporated by reference, including the “Risk Factors” sections of this prospectus, any accompanying prospectus supplement and our reports and other documents filed with the SEC, and such forward-looking statements included in this prospectus should not be unduly relied upon. When considering forward-looking statements, you should keep in mind the risks, uncertainties and other cautionary statements made in this prospectus, any accompanying prospectus supplement and the documents incorporated by reference.

Although we believe that the plans, intentions, expectations, assumptions and strategies reflected in our forward-looking statements are reasonable, these statements relate to future events or our future financial performance, and involve known and unknown risks, uncertainties and other factors which are, in some cases, beyond our control. If one or more of these risks or uncertainties occur, or if our underlying assumptions prove to be incorrect, actual results may vary significantly from those implied or projected by the forward-looking statements. In addition, we operate in a highly competitive and rapidly changing environment. New risks and uncertainties emerge from time to time, and it is not possible for us to predict all risks and uncertainties that could have an impact on the forward-looking statements. No forward-looking statement is a guarantee of future results. These statements are inherently uncertain and investors are cautioned not to unduly rely upon these statements.

There can be no assurance that other factors not currently anticipated by us will not materially and adversely affect our business, financial condition and results of operations. You are cautioned not to place undue reliance on any forward-looking statements made by us or on our behalf. Please take into account that forward-looking statements speak only as of the date of this prospectus or, in the case of any accompanying prospectus supplement or documents incorporated by reference, the date of any such document. Except as required by applicable law, we do not undertake any obligation to publicly correct or update any forward-looking statement.

RISK FACTORS

Investing in our securities involves risk. You should carefully consider the risks incorporated by reference to our Annual Report on Form 10-K, any subsequent Quarterly Reports on Form 10-Q or Current Reports on Form 8-K, and all other information contained or incorporated by reference into this prospectus and any applicable prospectus supplement as updated by our subsequent filings under the Exchange Act, and the risk factors and other information contained in any applicable prospectus supplement before acquiring any such securities. The risks and uncertainties described in our SEC filings are not the only ones facing us. Additional risks and uncertainties that we are unaware of, or that we currently believe are not material, may also become important factors that adversely affect our business. If any such risks and uncertainties actually occur, our business, financial condition, results of operations and prospects could be materially and adversely affected, the market price of our securities could decline and you could lose all or part of your investment. See “Where You Can Find More Information” and “Cautionary Note Regarding Forward-Looking Statements.”

USE OF PROCEEDS

Except as otherwise set forth in any accompanying prospectus supplement, we expect to use the net proceeds from the sale of securities for general corporate purposes, including the financing of our operations.

Unless set forth in an accompanying prospectus supplement, we will not receive any proceeds in the event that securities are sold by a selling securityholder.

DESCRIPTION OF SECURITIES

This prospectus contains summary descriptions of our common stock, preferred stock, depositary shares, warrants, subscription rights, purchase contracts and purchase units that may be offered and sold from time to time. These summary descriptions are not meant to be complete descriptions of each security. The particular terms of any security to be issued pursuant hereto will be set forth in a related prospectus supplement and/or free writing prospectus. This prospectus and the accompanying prospectus supplement and/or free writing prospectus will contain the material terms and conditions for each security.

DESCRIPTION OF Keel CAPITAL STOCK

The following summary description of the Keel capital stock is based on the provisions of the Delaware General Corporation Law (“DGCL”), our amended and restated certificate of incorporation (the “Keel Certificate”), and our bylaws (the “Keel Bylaws”). This description does not purport to be complete in all respects and is qualified entirely by reference to the full text of the DGCL, as it may be amended from time to time, the provisions of the Keel Certificate and the Keel Bylaws, as each may be amended from time to time, which are incorporated by reference as exhibits to the registration statement of which this prospectus is a part. See “Where You Can Find More Information.” As used in this “Description of Keel Capital Stock,” the terms “Keel,” the “Company”, “we,” “our” and “us” refer to Keel Infrastructure Corp., a Delaware corporation, and do not, unless otherwise specified, include our subsidiaries.

General

Keel’s authorized capital stock consists of 1,500,000,000 shares of common stock, par value US$0.001 per share (the “common stock”), and 120,000,000 shares of class A preferred stock, par value US$0.001 per share (the “preferred stock”).

Common Stock

Voting Rights

Each holder of common stock is entitled to one vote for each share on all matters submitted to a vote of the stockholders, including the election of directors. Holders of common stock do not have cumulative voting rights in the election of directors. Accordingly, in an uncontested election, holders of a majority of the voting shares are able to elect all of the directors.

Dividends

Subject to preferences that may be applicable to any then outstanding holders of Keel preferred stock, holders of common stock are entitled to receive dividends, if any, as may be declared from time to time by the board of directors of Keel (“Keel Board”) out of legally available funds. Under the DGCL, the Keel Board may declare and pay a dividend to holders common stock out of surplus or, if there is no surplus (as defined and computed in accordance with the DGCL), out of net profits for the fiscal year in which the dividend is declared or the immediately preceding fiscal year, or both. Dividends may be paid in cash, in common stock or in other property. Declaration and payment of any dividend is subject to the discretion of the Keel Board. Each quarter the Keel Board will review Keel’s dividend in light of Keel’s other financial commitments before declaring the dividend. Any decision to pay dividends on the common stock in the future will be made by the Keel Board on the basis of Keel’s earnings, financial requirements, provisions of the DGCL affecting the payment of distributions to stockholders and other factors existing at such future time.

Liquidation

In the event of Keel’s liquidation, dissolution or winding up, holders of common stock will be entitled to share ratably in the net assets legally available for distribution to stockholders after the payment of all of Keel’s debts and other liabilities and the satisfaction of any liquidation preference granted to the holders of any then outstanding shares of preferred stock. If a dissolution is authorized, a certificate of dissolution must be filed with the Secretary of State of the State of Delaware.

Rights and Preferences

Holders of common stock have no pre-emptive, conversion, subscription or other rights, and there are no redemption or sinking fund provisions applicable to common stock. The rights, preferences and privileges of the holders of common stock are subject to and may be adversely affected by the rights of the holders of shares of any series of Keel preferred stock that we may designate in the future.

Fully Paid and Non-assessable

All outstanding shares of common stock are fully paid and non-assessable.

Preferred Stock

The Keel Certificate authorizes the Keel Board to issue Keel preferred stock in one or more series and to determine the preferences, limitations and relative rights of any shares of Keel preferred stock that it shall choose to issue, without vote or action by the stockholders, subject to certain limitations on voting and other rights set forth in the Keel Certificate.

Annual Stockholder Meetings

The Keel Certificate and Keel Bylaws provide that annual stockholder meetings are held at a date, place (if any) and time, as exclusively selected by the Keel Board. To the extent permitted under applicable law, we may but are not obligated to conduct meetings by remote communications, including by webcast.

Anti-Takeover Effects of Provisions of the Keel Certificate, the Keel Bylaws and Delaware Law

Some provisions of the DGCL, the Keel Certificate and Keel Bylaws could make the following transactions difficult: acquisition of Keel by means of a tender offer; acquisition of Keel by means of a proxy contest or otherwise; and removal of incumbent officers and directors of Keel. It is possible that these provisions could make it more difficult to accomplish or could deter transactions that stockholders may otherwise consider to be in their best interest or in the best interests of Keel, including transactions that might result in a premium over the market price for our common stock.

These provisions, summarized below, are expected to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of Keel to first negotiate with the Keel Board. We believe that the benefits of protection to Keel’s potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure Keel outweigh the disadvantages of discouraging these proposals because negotiation of these proposals could result in an improvement of their terms.

Delaware Anti-Takeover Statutes

Keel is subject to Section 203 of the DGCL, which prohibits persons deemed “interested stockholders” from engaging in a “business combination” with a publicly held Delaware corporation for three years following the date these persons become interested stockholders unless the business combination is, or the transaction in which the person became an interested stockholder was, approved in a prescribed manner or another prescribed exception applies. Generally, an “interested stockholder” is a person who, together with affiliates and associates, owns, or within three years prior to the determination of interested stockholder status did own, 15% or more of a corporation’s voting stock and a “business combination” includes a merger, asset or stock sale, or other transaction resulting in a financial benefit to the interested stockholder. The existence of this provision may have an anti-takeover effect with respect to transactions not approved in advance by the Keel Board, such as discouraging takeover attempts that might result in a premium over the market price of our common stock.

Undesignated Preferred Stock

The ability to authorize undesignated Keel preferred stock makes it possible for the Keel Board to issue preferred stock with voting or other rights or preferences that could impede the success of any attempt to change control of Keel. These and other provisions may have the effect of deterring hostile takeovers or delaying changes in control or management of Keel.

Special Stockholder Meetings

The Keel Bylaws provide that a special meeting of stockholders may be called only by the Keel Board or by two or more stockholders holding at least 15% of the capital stock of the Company issued and outstanding and entitled to vote on the matter for which the special meeting is called.

Requirements for Advance Notification of Stockholder Nominations and Proposals

The Keel Bylaws establish advance notice procedures with respect to stockholder proposals and the nomination of candidates for election as directors, other than nominations made by or at the direction of the Keel Board or a committee of the Keel Board.

Stockholder Action by Unanimous Written Consent

The Keel Certificate and Keel Bylaws provide for the right of stockholders to act by unanimous written consent without a meeting.

Composition of the Board of Directors; Election and Removal of Directors; Filling Vacancies

The Keel Board consists of not less than one nor more than 10 directors. In any elections of directors, a director nominee for the Keel Board is elected by a plurality of the votes cast with respect to such director by the shares represented and entitled to vote at a meeting of the stockholders for the election of directors at which a quorum is present, voting together as a single class. The directors of Keel are elected until the expiration of the term for which they are elected and until their respective successors are duly elected and qualified.

The directors of Keel may be removed only by the affirmative vote of at least a majority of the holders of the issued and outstanding capital stock of the Company entitled to vote in the election of directors. Furthermore, any vacancy on the Keel Board, however occurring, including a vacancy resulting from an increase in the size of the board, may be filled only by a majority vote of the directors then in office, even if less than a quorum, by the sole remaining director, or by a majority of the votes cast by the stockholders. This system of electing and removing directors and filling vacancies may tend to discourage a third party from making a tender offer or otherwise attempting to obtain control of Keel, because it generally makes it more difficult for stockholders to replace a majority of the directors.

Choice of Forum

The Keel Certificate and Keel Bylaws provide that, except for claims for which the U.S. federal courts have jurisdiction, unless Keel consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware is the exclusive forum for: any derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty; any action asserting a claim against us arising pursuant to the DGCL, the Keel Certificate or the Keel Bylaws; or any action asserting a claim against Keel that is governed by the internal affairs doctrine. Although the Keel Certificate contains the choice of forum provision described above, it is possible that a court could find that such a provision is inapplicable for a particular claim or action or that such provision is unenforceable.

Amendment of the Keel Certificate and Keel Bylaws

The amendment of any of the provisions in the Keel Certificate requires approval by a stockholder vote by the holders of at least a majority of the voting power of the then outstanding voting stock voting as a single class. The Keel Bylaws may be amended by the Keel Board or by the holders of at least a majority of the voting power of the then outstanding voting stock voting as a single class.

The provisions of the DGCL, the Keel Certificate and Keel Bylaws could have the effect of discouraging others from attempting hostile takeovers and, as a consequence, they may also inhibit temporary fluctuations in the market price of our common stock that often result from actual or rumored hostile takeover attempts. These provisions may also have the effect of preventing changes in the management of Keel. It is possible that these provisions could make it more difficult to accomplish transactions that stockholders may otherwise deem to be in their best interests.

Limitations of Liability and Indemnification Matters

The Keel Certificate contains provisions that limit the liability of the directors and officers of Keel for monetary damages to the fullest extent permitted by Delaware law. Consequently, Keel directors and officers are not personally liable to Keel or its stockholders for monetary damages for any breach of fiduciary duties as directors, except liability for:

Each of the Keel Certificate and Keel Bylaws provide that we are required to indemnify the directors and officers of Keel, in each case to the fullest extent permitted by the DGCL. The Keel Bylaws also obligate us to advance expenses incurred by a director or officer in advance of the final disposition of any action or proceeding, and permit us to secure insurance on behalf of any officer, director, employee or other agent for any liability arising out of his or her actions in that capacity regardless of whether we would otherwise be permitted to indemnify him or her under the DGCL. We have entered into agreements with the Keel directors, executive officers and other employees as determined by the Keel Board. With specified exceptions, these agreements provide for indemnification for related expenses including, among other things, attorneys’ fees, judgments, fines and settlement amounts incurred by any of these individuals in any action or proceeding to the fullest extent permitted by applicable law. We believe that these bylaw provisions and indemnification agreements are necessary to attract and retain qualified persons as directors and officers. Keel also maintains directors’ and officers’ liability insurance.

The limitation of liability and indemnification provisions in the Keel Certificate and Keel Bylaws may discourage stockholders from bringing a lawsuit against Keel directors and officers for breach of their fiduciary duty. They may also reduce the likelihood of derivative litigation against Keel directors and officers, even though an action, if successful, might benefit Keel and its stockholders. Furthermore, a stockholder’s investment may be adversely affected to the extent that we pay the costs of settlement and damage.

Uncertificated Shares

Holders of common stock do not have the right to require Keel to issue certificates for their shares. Keel only issues uncertificated shares of common stock, provided that the Keel Board may provide by resolution that some or all of the shares of any class or series of stock of Keel shall be represented by certificates.

No Sinking Fund

The shares of Keel common stock have no sinking fund provisions.

Stock Exchange Listing

The shares of Keel common stock are listed on the Nasdaq and the TSX under the symbol “KEEL.”

Transfer Agent and Registrar

The transfer agent and registrar for the shares of Keel common stock is Continental Stock Transfer & Trust Company.

DESCRIPTION OF DEPOSITARY SHARES

We may offer depositary receipts representing fractional shares of our preferred stock, rather than full shares of preferred stock. The shares of preferred stock represented by depositary shares will be deposited under a depositary agreement between us and a bank or trust company that meets certain requirements and is selected by us (the “Bank Depositary”). Each owner of a depositary share will be entitled to all the rights and preferences of the preferred stock represented by the depositary share.

The description in an accompanying prospectus supplement of any depositary shares we offer will not necessarily be complete and will be qualified in its entirety by reference to the applicable depositary agreement, which will be filed with the SEC if we offer depositary shares. For more information on how you can obtain copies of any depositary agreement if we offer depositary shares, see “Where You Can Find More Information.” We urge you to read the applicable depositary agreement and any accompanying prospectus supplement in their entirety.

Dividends and Other Distributions

If we pay a cash distribution or dividend on a series of preferred stock represented by depositary shares, the Bank Depositary will distribute such dividends to the record holders of such depositary shares. If the distributions are in property other than cash, the Bank Depositary will distribute the property to the record holders of the depositary shares. However, if the Bank Depositary determines that it is not feasible to make the distribution of property, the Bank Depositary may, with our approval, sell such property and distribute the net proceeds from such sale to the record holders of the depositary shares.

Redemption of Depositary Shares

If we redeem a series of preferred stock represented by depositary shares, the Bank Depositary will redeem the depositary shares from the proceeds received by the Bank Depositary in connection with the redemption. The redemption price per depositary share will equal the applicable fraction of the redemption price per share of the preferred stock. If fewer than all the depositary shares are redeemed, the depositary shares to be redeemed will be selected by lot or pro rata as the Bank Depositary may determine.

Voting the Preferred Stock

Upon receipt of notice of any meeting at which the holders of the preferred stock represented by depositary shares are entitled to vote, the Bank Depositary will mail the notice to the record holders of the depositary shares relating to such preferred stock. Each record holder of these depositary shares on the record date, which will be the same date as the record date for the preferred stock, may instruct the Bank Depositary as to how to vote the preferred stock represented by such holder’s depositary shares. The Bank Depositary will endeavor, insofar as practicable, to vote the amount of the preferred stock represented by such depositary shares in accordance with such instructions, and we will take all action that the Bank Depositary deems necessary in order to enable the Bank Depositary to do so. The Bank Depositary will abstain from voting shares of the preferred stock to the extent it does not receive specific instructions from the holders of depositary shares representing such preferred stock.

Amendment and Termination of the Depositary Agreement

The form of depositary receipt evidencing the depositary shares and any provision of the depositary agreement may be amended by agreement between the Bank Depositary and us. However, any amendment that materially and adversely alters the rights of the holders of depositary shares will not be effective unless such amendment has been approved by the holders of at least a majority of the depositary shares then outstanding. The depositary agreement may be terminated by the Bank Depositary or us only if (1) all outstanding depositary shares have been redeemed or (2) there has been a final distribution in respect of the preferred stock in connection with any liquidation, dissolution or winding up of our company and such distribution has been distributed to the holders of depositary receipts.

Withdrawal of Preferred Stock

Except as may be provided otherwise in an accompanying prospectus supplement, upon surrender of depositary receipts at the principal office of the Bank Depositary, subject to the terms of the depositary agreement, the owner of the depositary shares may demand delivery of the number of whole shares of preferred stock and all money and other property, if any, represented by those depositary shares. Partial shares of preferred stock will not be issued. If the depositary receipts delivered by the holder evidence a number of depositary shares in excess of the number of depositary shares representing the number of whole shares of preferred stock to be withdrawn, the Bank Depositary will deliver to such holder at the same time a new depositary receipt evidencing the excess number of depositary shares. Holders of withdrawn preferred stock may not thereafter deposit those shares under the depositary agreement or receive depositary receipts evidencing depositary shares therefor.

DESCRIPTION OF WARRANTS

We may issue warrants for the purchase of shares of our common stock or shares of preferred stock. We may issue warrants independently or together with other securities, and they may be attached to or separate from the other securities. Each series of warrants is expected to be issued under a separate warrant agreement that we will enter into with a bank or trust company, as warrant agent, as detailed in an accompanying prospectus supplement. The warrant agent will act solely as our agent in connection with the warrants and will not assume any obligation, or agency or trust relationship, with you.

The prospectus supplement relating to a particular issue of warrants will describe the terms of those warrants, including, when applicable:

After warrants expire they will become void. The prospectus supplement may provide for the adjustment of the exercise price of the warrants.

Warrants may be exercised at the appropriate office of the warrant agent or any other office indicated in an accompanying prospectus supplement. Before the exercise of warrants, holders will not have any of the rights of holders of the securities purchasable upon exercise and will not be entitled to payments made to holders of those securities.

The description in an accompanying prospectus supplement of any warrants we offer will not necessarily be complete and will be qualified in its entirety by reference to the applicable warrant agreement, which will be filed with the SEC if we offer warrants. For more information on how you can obtain copies of any warrant agreement if we offer warrants, see “Where You Can Find More Information.” We urge you to read the applicable warrant agreement and any accompanying prospectus supplement in their entirety.

DESCRIPTION OF SUBSCRIPTION RIGHTS

We may issue subscription rights to purchase shares of our common stock or shares of our preferred stock. We may issue subscription rights independently or together with any other offered security, which may or may not be transferable by the stockholder. In connection with any offering of subscription rights, we may enter into a standby arrangement with one or more underwriters or other purchasers pursuant to which the underwriters or other purchasers may be required to purchase any securities remaining unsubscribed for after such offering.

DESCRIPTION OF PURCHASE CONTRACTS AND PURCHASE UNITS

We may issue purchase contracts, including contracts obligating holders to purchase from us, and obligating us to sell to the holders, a specified number of shares of our common stock or shares of our preferred stock at a future date or dates, which we refer to in this prospectus as purchase contracts. The price of the securities and the number of securities may be fixed at the time the purchase contracts are issued or may be determined by reference to a specific formula set forth in the purchase contracts, and may be subject to adjustment under anti-dilution formulas. The purchase contracts may be issued separately or as part of units consisting of a stock purchase contract and our preferred securities or debt obligations of third parties, including U.S. treasury securities, or any combination of the foregoing, securing the holders’ obligations to purchase the securities under the purchase contracts, which we refer to herein as purchase units. The purchase contracts may require holders to secure their obligations under the purchase contracts in a specified manner. The purchase contracts also may require us to make periodic payments to the holders of the purchase contracts or the purchase units, as the case may be, or vice versa, and those payments may be unsecured or pre-funded in whole or in part.

The description in an accompanying prospectus supplement of any purchase contract or purchase unit we offer will not necessarily be complete and will be qualified in its entirety by reference to the applicable purchase contract or purchase unit, which will be filed with the SEC if we offer purchase contracts or purchase units.

If so, the third party may use securities borrowed from us or the selling securityholders or others to settle such sales and may use securities received from us to close out any related short positions.

PART II INFORMATION NOT REQUIRED IN PROSPECTUS

Item 14. Other Expenses of Issuance and Distribution.

The following table sets forth the expenses to be borne by the registrant in connection with the offerings described in this registration statement.

Item 15. Indemnification of Directors and Officers.

The registrant is a Delaware corporation. Reference is made to Section 102(b)(7) of the General Corporation Law of the State of Delaware (the “DGCL”), which enables a corporation in its certificate of incorporation to eliminate or limit the personal liability of a director or officer for monetary damages to stockholders for violations of the director’s or officer’s fiduciary duty, except:

The registrant’s Amended and Restated Certificate of Incorporation limits the personal liability of a director or officer to the registrant and its stockholders for monetary damages for a breach of fiduciary duty as a director or officer to the fullest extent permitted by the DGCL.

Reference is also made to Section 145 of the DGCL, which provides that a corporation may indemnify any persons, including directors and officers, who are, or are threatened to be made, parties to any threatened, pending or completed legal action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of such corporation), by reason of the fact that such person is or was a director, officer, employee or agent of such corporation or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, provided such director, officer, employee or agent acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe that the person’s conduct was unlawful. A Delaware corporation may indemnify directors and officers in an action by or in the right of the corporation under the same conditions, except that no indemnification is permitted without judicial approval if the director or officer is adjudged to be liable to the corporation unless a court believes that in light of all the circumstances indemnification should apply. Where a director or officer is successful on the merits or otherwise in the defense of any action referred to above, the corporation must indemnify him or her against the expenses that such director or officer actually and reasonably incurred. The indemnification permitted under the DGCL is not exclusive, and a corporation is empowered to purchase and maintain insurance against liabilities whether or not indemnification would be permitted by statute.

The registrant’s Amended and Restated Certificate of Incorporation and Bylaws provide for indemnification of its directors and officers to the fullest extent currently permitted by the DGCL. The registrant also has indemnification agreements with its directors and officers. In addition, the registrant maintains liability insurance for its directors and officers.

In connection with an offering of the securities registered hereunder, the registrant may enter into an underwriting agreement which may provide that the underwriters are obligated, under certain circumstances, to indemnify directors, officers and controlling persons of the registrant against certain liabilities, including liabilities under the Securities Act.

Item 16. List of Exhibits.

The Exhibits to this registration statement are listed in the Exhibit Index on page II-2.

Item 17. Undertakings.

The undersigned registrant hereby undertakes:

provided, however, that paragraphs (i), (ii) and (iii) of this section do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the 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 this registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of this registration statement;

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 SEC 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.
