Resideo (REZI) S-3ASRAutomatic shelf registration

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”), utilizing a “shelf” registration process for the delayed offering and sale of securities pursuant to Rule 415 under the Securities Act. Under this shelf registration process, we may from time to time offer to sell shares of common stock, preferred stock, warrants to purchase any such securities and debt securities in one or more offerings. This prospectus provides you with a general description of the securities we may offer. Each time we offer a type or series of such securities, we will provide a prospectus supplement that will contain specific information about the terms of that offering. If information in this prospectus is inconsistent with any accompanying prospectus supplement, you should rely on the prospectus supplement. However, if any statement in one of these documents is inconsistent with a statement in another document having a later date—for example, a document incorporated by reference in this prospectus—the statement in the document having the later date modifies or supersedes the earlier statement as our business, financial condition, results of operations and prospects may have changed since the earlier dates. You should read this prospectus, any accompanying prospectus supplement, the documents and the information incorporated by reference in this prospectus and any accompanying prospectus supplement and any free writing prospectus that we have authorized for use in connection with an offering when making your investment decision. You should also read and consider the information in the documents we have referred you to under the headings “Where You Can Find More Information” and “Incorporation by Reference.” You should not consider any information in this prospectus or the accompanying prospectus supplement to be investment, legal or tax advice. You should consult your own counsel, accountants and other advisers for legal, tax, business, financial and related advice regarding the purchase of our securities offered by this prospectus.

We have not authorized anyone to provide you with different or additional information other than that contained in or incorporated by reference into this prospectus, any accompanying prospectus supplement or any related free writing prospectus that we authorize for use in connection with an offering. We do not take any responsibility for, or provide any assurance as to the reliability of, any other information that others may give you. This prospectus and any accompanying prospectus supplement do not constitute an offer to sell or the solicitation of an offer to buy our securities other than our securities described in such accompanying prospectus supplement or an offer to sell or the solicitation of an offer to buy our securities in any circumstances in which such offer or solicitation is unlawful. You should assume that the information appearing in this prospectus, any prospectus supplement, the documents incorporated by reference and any related free writing prospectus is accurate only as of their respective dates. Our business, financial condition, results of operations and prospects may have changed materially since those dates.

Unless the context requires otherwise, references in this prospectus to “Resideo,” the “Company,” “we,” “us,” and “our” refer to Resideo Technologies, Inc. together with its consolidated subsidiaries.

In this prospectus, we refer to the common stock, preferred stock, warrants and debt securities being offered, collectively, as “securities.”

This prospectus and the documents incorporated herein by reference contain “forward-looking statements” that involve risks and uncertainties. These statements can be identified by the fact that they do not relate strictly to historical or current facts, but rather are based on current expectations, estimates, assumptions and projections about our industries and our business and financial results. Forward-looking statements often include words such as “anticipates,” “estimates,” “expects,” “projects,” “forecasts,” “intends,” “plans,” “continues,” “believes,” “may,” “will,” “goals” and words and terms of similar substance in connection with discussions of future operating or financial performance. As with any projection or forecast, forward-looking statements are inherently susceptible to uncertainty and changes in circumstances. Our actual results may vary materially from those expressed or implied in our forward-looking statements. Accordingly, undue reliance should not be placed on any forward-looking statement made by us or on our behalf. Although we believe that the forward-looking statements contained in this prospectus and the documents incorporated herein by reference are based on reasonable assumptions, you should be aware that many factors could affect our actual financial results or results of operations and could cause actual results to differ materially from those in such forward-looking statements, including but not limited to:

These and other factors are more fully discussed in the “Risk Factors” section of this prospectus and in our Annual Report on Form 10-K and Quarterly Reports on Form 10-Q incorporated herein by reference and the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” sections of such reports. These risks could cause actual results to differ materially from those implied by forward-looking statements in this prospectus and the documents incorporated herein by reference. Even if our results of operations, financial condition and liquidity and the development of the industries in which we operate are consistent with the forward-looking statements contained in this prospectus and the documents incorporated herein by reference, those results or developments may not be indicative of results or developments in subsequent periods.

Any forward-looking statements made by us in this prospectus and the documents incorporated herein by reference speak only as of the date on which they are made. We are under no obligation to, and expressly disclaim any obligation to, update or alter our forward-looking statements, whether as a result of new information, subsequent events or otherwise.

On October 29, 2018, we separated from Honeywell International Inc. (“Honeywell”), becoming an independent publicly traded company as a result of a pro rata distribution of our common stock to shareholders of Honeywell (the “Spin-Off”). Our common stock began trading “regular way” under the ticker symbol “REZI” on the NYSE on October 29, 2018.

Investing in our securities involves significant risks. Please see the risk factors described in our most recently filed Annual Report on Form 10-K and Quarterly Reports on Form 10-Q, which are incorporated by reference in this prospectus and in any accompanying prospectus supplement. Before making an investment decision, you should carefully consider these risks as well as other information we include or incorporate by reference in this prospectus, including those described under “Cautionary Note Regarding Forward-Looking Statements.” The risks and uncertainties we have described are not the only ones facing our company. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our business operations.

Unless otherwise indicated in any applicable prospectus supplement, we intend to use the net proceeds from the sale of any securities offered under this prospectus for general corporate purposes.

The summary of the general terms and provisions of our capital stock set forth below does not purport to be complete and is subject to and qualified by reference to the Company’s Amended and Restated Certificate of Incorporation (our “Certificate”) and Amended and Restated By-laws (our “By-laws” and together with our Certificate, our “Charter Documents”), each of which is attached as an exhibit to our most recent Annual Report on Form 10-K incorporated herein by reference. For additional information, please read our Charter Documents and the applicable provisions of the Delaware General Corporation Law (the “DGCL”).

Our authorized capital stock consists of 700,000,000 shares of common stock, par value $0.001 per share, and 100,000,000 shares of preferred stock, par value $0.001 per share. The number of authorized shares of either the common stock or preferred stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of at least a majority of our voting stock entitled to vote, voting as a single class. The common stock is our only class of securities registered under Section 12 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

The holders of shares of our common stock are entitled to receive dividends when, as and if declared by our Board of Directors (our “Board”) at its discretion out of funds legally available for that purpose, subject to applicable law and the preferential rights of any preferred stock that may be outstanding.

The holders of our common stock are entitled to one vote for each share held of record on all matters submitted to a vote of the stockholders. Corporate actions to be taken by vote of the stockholders generally require the vote of holders of a majority in voting power of the shares of capital stock of the Company entitled to vote on the matter and who are present in person or represented by proxy, except as otherwise required by law or provided in the Charter Documents. Our Certificate does not provide for cumulative voting by stockholders in the election of directors. Directors are elected by the affirmative vote of the majority of votes cast, except that if the number of nominees exceeds the number of directors to be elected, the directors are elected by a plurality of the votes cast, up to the number of directors to be elected in such meeting. A majority of the votes cast means that the number of shares voted “for” a director must exceed the number of votes cast “against” that director.

Subject to the preferential liquidation rights of any preferred stock that may be outstanding, upon our liquidation, dissolution or winding-up, the holders of our common stock will be entitled to share ratably in our assets legally available for distribution to our stockholders.

The issued and outstanding shares of our common stock are fully paid and non-assessable.

The holders of our common stock are not entitled to preemptive rights or preferential rights to subscribe for shares of our capital stock or rights to redeem or convert the holders’ shares of our common stock.

The transfer agent and registrar for our common stock is Broadridge Corporate Issuer Solutions, Inc.

Our common stock is listed on the NYSE, under the ticker symbol “REZI.”

Our Certificate authorizes our Board to designate and issue from time to time one or more series of preferred stock without stockholder approval. Our Board may fix the number of shares constituting each such series and the designation of such series, the voting powers (if any) of the shares of such series, and the preferences and relative, participating, optional and other rights, if any, and any qualifications, limitations or restrictions, of the shares of each such series.

The particular terms of any series of preferred stock will be designated pursuant to a certificate of designation adopted by our Board or a duly authorized committee of our Board, which will be described in the prospectus supplement relating to the offering. Such terms will include the terms, if any, on which shares of any series of preferred stock are convertible or exchangeable into common stock. These terms may include provisions for conversion or exchange, either mandatory, at the option of the holder, or at our option, in which case the number of shares of common stock to be received by the holders of preferred stock would be calculated as of a time and in the manner stated in the applicable prospectus supplement. The description of the terms of a particular series of preferred stock that will be set forth in the applicable prospectus supplement does not purport to be complete and is qualified in its entirety by reference to the certificate of designation relating to the series.

Our Charter Documents and the DGCL contain certain provisions that may discourage an unsolicited takeover of the Company or make an unsolicited takeover of the Company more difficult. The following are some of the more significant anti-takeover provisions that are applicable to the Company:

In general, Section 203 of the DGCL prohibits a Delaware corporation with a class of voting stock listed on a national securities exchange or held of record by 2,000 or more stockholders from engaging in a “business combination” with an “interested stockholder” for a three-year period following the time that this stockholder becomes an interested stockholder, unless the business combination is approved in a prescribed manner. A “business combination” includes, among other things, a merger, asset or stock sale or other transaction resulting in a financial benefit to the interested stockholder. An “interested stockholder” is a person who, together with affiliates and associates, owns, or did own within three years prior to the determination of interested stockholder status, 15% or more of the corporation’s voting stock. Under Section 203, a business combination between a corporation and an interested stockholder is prohibited unless it satisfies one of the following conditions:

The DGCL permits a corporation to opt out of, or choose not to be governed by, its anti-takeover statute by expressly stating so in its original certificate of incorporation (or subsequent amendment to its certificate of incorporation or bylaws approved by its stockholders). The Certificate does not contain a provision expressly opting out of the application of Section 203 of the DGCL; therefore, the Company is subject to the anti-takeover statute.

Our Certificate provides, in all cases to the fullest extent permitted by law, that unless we consent in writing to the selection of an alternative forum, the Court of Chancery located within the State of Delaware will be the sole and exclusive forum for any derivative action or proceeding brought on behalf of the Company, any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee or stockholder of the Company to the Company or the Company’s stockholders, any action asserting a claim arising pursuant to the DGCL or as to which the DGCL confers jurisdiction on the Court of Chancery located in the State of Delaware, any action asserting a claim governed by the internal affairs doctrine or any other action asserting an “internal corporate claim” as that term is defined in Section 115 of the DGCL. However, if the Court of Chancery within the State of Delaware does not have jurisdiction, the action may be brought in any other state or federal court located within the State of Delaware.

The following description, together with the additional information we may include in any applicable prospectus supplement, summarizes the material terms and provisions of the warrants that we may offer under this prospectus and the related warrant agreements and warrant certificates. While the terms summarized below will apply generally to any warrants that we may offer, we will describe the particular terms of any series of warrants in more detail in the applicable prospectus supplement. The terms of any warrants offered under an applicable prospectus supplement may differ from the terms described below as set forth therein. Specific warrant agreements will contain additional important terms and provisions and will be incorporated by reference as an exhibit to the registration statement of which this prospectus forms a part.

We may issue warrants for the purchase of common stock and/or preferred stock in one or more series. We may issue warrants independently or together with common stock and/or preferred stock, and the warrants may be attached to or separate from these securities.

We will evidence each series of warrants by warrant certificates that we will issue under a separate warrant agreement. We will enter into the warrant agreement with a warrant agent. We will indicate the name and address of the warrant agent in the applicable prospectus supplement relating to a particular series of warrants.

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

The debt securities will be direct obligations of the Company and will be either senior or subordinated debt securities and may be either secured or unsecured. The debt securities will be issued under one or more indentures between us and a trustee to be named therein (the “Trustee”), the form of which is attached as an exhibit to the registration statement of which this prospectus forms a part (the “Base Indenture”). While the terms we have summarized below will apply generally to any debt securities that we may offer under this prospectus, we will describe the particular terms of any debt securities that we may offer in more detail in the applicable prospectus supplement. The terms of any debt securities offered under a prospectus supplement may differ from the terms described below. Unless the context requires otherwise, whenever we refer to the indenture, we also are referring to any supplemental indentures that specify the terms of a particular series of debt securities. For purposes of this description of debt securities, references to “the Company,” “we,” “our” and “us” refer only to Resideo Technologies, Inc. and not to its subsidiaries.

We may issue debt securities in one or more series. A supplemental indenture may set forth specific terms of a series of debt securities. There will be a prospectus supplement relating to particular series of debt securities. Each prospectus supplement will describe with respect to the particular series of debt securities offered:

The applicable prospectus supplement will describe any financial covenants that apply to a series of debt securities, if applicable.

We may issue debt securities at a discount from, or at a premium to, their stated principal amount. A prospectus supplement may describe federal income tax considerations and other special considerations applicable to a debt security issued with original issue discount or a premium.

If the principal of, premium, if any, or interest, if any, with regard to any series of debt securities is payable in a foreign currency, then the prospectus supplement relating to those debt securities will describe any restrictions on currency conversions, tax considerations or other material restrictions with respect to that series of debt securities.

We may issue debt securities in certificated or uncertificated form, in registered form with or without coupons or in bearer form with coupons, if applicable.

We may issue debt securities of a series in the form of one or more global certificates evidencing all or a portion of the aggregate principal amount of the debt securities of that series. We may deposit the global certificates with depositaries, and the global certificates may be subject to restrictions upon transfer or upon exchange for debt securities in individually certificated form.

An event of default with respect to each series of debt securities will include:

The Trustee may withhold notice to the holders of any series of debt securities of any default (except a default in payment of principal, premium, if any, or interest, if any) if the Trustee considers it in the interest of the holders of the series to do so.

The Trustee will give to the holders of any debt securities of a series notice of any default with regard to such debt securities of that series known to the Trustee (upon receipt in writing by a trust officer), within 90 days after it occurs; provided, that, except in the case of a default in the payment of the principal of, or premium, if any, or interest on any debt security, the Trustee will be protected in withholding notice of the default if and so long as a committee of its trust officers in good faith determines it in the interest of the holders of the series to do so.

If any event of default occurs and is continuing, the Trustee, by notice to us, or the holders of not less than 25% in aggregate principal amount of the series of debt securities then outstanding, by notice to us and the Trustee, may declare the principal of and accrued interest, if any, on all the debt securities of that series to be due and payable immediately. However, if we cure all events of default (except the failure to pay principal, premium or interest which became due solely because of the acceleration) and certain other conditions are met, that declaration may be rescinded and past defaults may be waived by the holders of a majority in aggregate principal amount of the series of debt securities then outstanding.

The holders of a majority of the outstanding principal amount of a series of debt securities will have the right to direct the time, method and place of conducting proceedings for any remedy available to the Trustee, subject to certain limitations specified in the indenture.

A prospectus supplement will describe any additional or different events of default and remedies which apply to any series of debt securities.

Unless otherwise indicated in the applicable prospectus supplement (and any related supplemental indenture relating to a particular series of debt securities), we and the Trustee may, without the consent of holders of debt securities, modify the indenture to (i) cure errors, omissions, defects, inconsistencies or ambiguities, (ii) comply with covenants in the indenture described below under the heading “Mergers and Other Transactions,” (iii) establish the form and terms of any debt securities of any series as contemplated in the indenture, (iv) provide for uncertificated debt securities in addition to or in place of certificated debt securities or (v) amend, modify or supplement the Base Indenture or any supplemental indenture, to make any change that does not materially adversely affect the rights of any holder of debt securities, provided that any amendment, modification or supplement that conforms the Base Indenture or any supplemental indenture, as applied to any series of debt securities, to the terms described in the prospectus (including any prospectus supplement) pursuant to which such debt securities were initially sold shall be deemed not to adversely affect the rights of holders.

We and the Trustee may also (i) amend or supplement the indenture or the debt securities without notice to any holder but with the written consent of the holders of a majority in aggregate principal amount of the debt securities of all series then outstanding or (ii) supplement the Base Indenture with regard to a series of debt securities, amend or supplement any supplemental indenture relating to a series of debt securities, or amend the debt securities of a series, without notice to any holder but with the written consent of the holders of a majority in aggregate principal amount of the debt securities of that series then outstanding. The holders of a majority in principal amount of the debt securities of all series then outstanding may waive compliance by us with any provision of the indenture or the debt securities without notice to any holder. The holders of a majority in principal amount of the debt securities of any series then outstanding may waive compliance with any provision of the Base Indenture, any supplemental indenture or the debt securities of that series with regard to the debt securities of that series without notice to any holder. However, without the consent of the holder so affected, no amendment, supplement or waiver, including a waiver of existing events of default, may: extend the fixed maturity of any debt securities, reduce the rate or extend the time for payment of interest, if any, on any debt securities, reduce the principal amount of any debt securities or the premium, if any, on any debt securities, impair or affect the right of a holder to institute suit for the payment of principal, premium, if any, or interest, if any, with regard to any debt securities, change the currency in which any debt securities are payable or impair the right, if any, to convert any debt securities into common stock or any other of our securities, reduce the percentage of debt securities required to consent to an amendment, supplement or waiver, reduce the amount payable upon the redemption of any debt security or change the time at which any debt security may or will be redeemed, modify the provisions of any supplemental indenture with respect to subordination of any debt securities of a series in a manner adverse to the holders or make any change to certain provisions of the indenture relating to, among other things, the right of holders of debt securities to receive payment of the principal of, premium and interest on those debt securities, to demand conversion and to waive existing events of default.

Unless otherwise indicated in the applicable prospectus supplement (and any related supplemental indenture relating to a particular series of debt securities), we may not consolidate with or merge into any other entity, or convey, transfer or lease our properties and assets substantially as an entirety to another person, unless (1) the entity formed by the consolidation or into which we are merged, or which acquires or leases our properties and assets substantially as an entirety, is a corporation organized and existing under the laws of the United States of America, a State of the United States of America or the District of Columbia, and assumes by a supplemental indenture all our obligations with regard to outstanding debt securities and our other covenants under the indenture, (2) with regard to each series of debt securities, immediately after giving effect to the transaction, no event of default with respect to

Upon any event described in the immediately preceding paragraph, the successor entity will succeed to and be substituted for us, and may exercise every right of ours under the Base Indenture and any supplemental indenture relating to outstanding series of debt securities, and the predecessor entity will be relieved of all obligations and covenants under the Base Indenture and any supplemental indenture.

You should note that if the Trustee becomes a creditor of ours, the indenture and the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”) limit the rights of the Trustee to obtain payment of claims in certain cases, or to realize on certain property received in respect of certain claims, as security or otherwise. The Trustee and its affiliates may engage in, and will be permitted to continue to engage in, other transactions with us and our affiliates. If, however, the Trustee, acquires any “conflicting interest” within the meaning of the Trust Indenture Act, it must eliminate the conflict or resign.

The holders of a majority in principal amount of the then outstanding debt securities of any series may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee with regard to that series or of exercising any trust or power conferred on the Trustee with regard to the debt securities of that series. However, the Trustee may refuse to follow any direction that conflicts with law or the indenture or, subject to the indenture, that the Trustee determines is unduly prejudicial to the rights of other holders or that would involve the Trustee in personal liability; provided, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. Prior to taking any action as a result of a direction given under this paragraph, the Trustee will be entitled to indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking that action. If an event of default occurs and is continuing, the Trustee, in the exercise of its rights and powers, must use the degree of care and skill in their exercise, as a prudent person would exercise in the conduct of his or her own affairs, provided that, the Trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request of any of the holders of the debt securities, unless they have offered to the Trustee indemnity or security satisfactory to the Trustee.

Each of the Base Indenture, any supplemental indenture and the debt securities issued thereunder will be governed by, and construed in accordance with, the laws of the State of New York.

We may sell our securities from time to time pursuant to underwritten public offerings, negotiated transactions, block trades or a combination of these methods. We may sell our securities separately or together:

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

The related prospectus supplement will set forth the terms of each offering, including:

We may solicit directly offers to purchase securities being offered by this prospectus. We may also designate agents to solicit offers to purchase our securities from time to time. We may sell our securities offered by this prospectus by any method permitted by law, including sales deemed to be an “at the market” offering as defined in Rule 415(a)(4) under the Securities Act, including without limitation sales made directly on the NYSE, on any other existing trading market for our securities or to or through a market maker. We will name in a prospectus supplement any agent involved in the offer or sale of our securities.

If we utilize a dealer in the sale of our securities being offered by this prospectus, we will sell our securities to the dealer, as principal. The dealer may then resell our securities to the public at varying prices to be determined by the dealer at the time of resale.

If we utilize an underwriter in the sale of our securities being offered by this prospectus, we will execute an underwriting agreement with the underwriter at the time of sale and we will provide the name of any underwriter in the prospectus supplement that the underwriter will use to make resales of our securities to the public. In connection with the sale of our securities, we or the purchasers of our securities for whom the underwriter may act as agent may compensate the underwriter in the form of underwriting discounts or commissions. The underwriter may sell our securities to or through dealers, and the underwriter may compensate those dealers in the form of discounts, concessions or commissions.

We will provide in the applicable prospectus supplement any compensation we will pay to underwriters, dealers or agents in connection with the offering of our securities, and any discounts, concessions or commissions allowed by underwriters to participating dealers. In compliance with guidelines of the Financial Industry Regulatory Authority, Inc., or FINRA, the maximum consideration or discount to be received by any FINRA member or independent broker dealer may not exceed 8% of the aggregate amount of securities pursuant to this prospectus and any applicable prospectus supplement. Underwriters, dealers and agents participating in the distribution of our securities may be deemed to be underwriters within the meaning of the Securities Act, and any discounts and commissions received by them and any profit realized by them on resale of our securities may be deemed to be underwriting discounts and commissions. In the event that an offering made pursuant to this prospectus is subject to FINRA Rule 5121, the prospectus supplement will comply with the prominent disclosure provisions of that rule.

To facilitate the offering of our securities, certain persons participating in the offering may engage in transactions that stabilize, maintain or otherwise affect the price of our securities. This may include over-allotments or short sales of our securities, which involves the sale by persons participating in the offering of more securities than we sold to them. In these circumstances, these persons would cover such over-allotments or short positions by making purchases in the open market or by exercising an option to purchase additional securities. In addition, these persons may stabilize or maintain the price of our securities by bidding for or purchasing our securities in the open market or by imposing penalty bids, whereby selling concessions allowed to dealers participating in the offering may be reclaimed if the securities sold by them are repurchased in connection with stabilization transactions. The effect of these transactions may be to stabilize or maintain the market price of our securities at a level above that which might otherwise prevail in the open market. These transactions may be discontinued at any time.

We may authorize underwriters, dealers or agents to solicit offers by certain purchasers to purchase our securities from us at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. The contracts will be subject only to those conditions set forth in the prospectus supplement, and the prospectus supplement will set forth any commissions we pay for solicitation of these contracts.

We may enter into derivative transactions with third parties, or sell our securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement so indicates, in connection with any derivative transaction, the third parties may sell our securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third party may use our securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of securities, and may use our securities received from us in settlement of those derivatives to close out any related open borrowings of securities. The third party in such sale transactions will be an underwriter and will be identified in the applicable prospectus supplement or a post-effective amendment to the registration statement of which this prospectus is a part. In addition, we may otherwise loan or pledge our securities to a financial institution or other third party that in turn may sell our 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.

Any securities offered other than common stock will be a new issue and, other than the common stock, which is listed on the NYSE, will have no established trading market. We may elect to list any series of securities on an exchange, and in the case of the common stock, on any additional exchange, but, unless otherwise specified in the applicable prospectus supplement and/or other offering material, we shall not be obligated to do so. No assurance can be given as to the liquidity of the trading market for any of the securities.

The underwriters, dealers and agents may engage in transactions with us, or perform services for us, in the ordinary course of business. We may provide the underwriters, dealers and agents with indemnification against civil liabilities, including liabilities under the Securities Act, or contribution with respect to payments that they may make with respect to these liabilities.
