Preliminary Prospectus Supplement

(To Prospectus Dated December 7, 2018)

Subscription Rights to Purchase Up to                 Shares of Common Stock at $                 per Share

We are distributing to holders of shares of our common stock who are entitled to participate in this offering, at no charge, non-transferable subscription rights to purchase up to an aggregate of                 shares of our common stock.  We refer to the offering that is the subject of this prospectus supplement as the Rights Offering.  In the Rights Offering, you will receive one subscription right, or a Subscription Right, for every share of our common stock owned at 5:00 p.m., Eastern Time, on November 18, 2019, the record date of the Rights Offering, or the Record Date.  Each Subscription Right consists of a basic subscription right, or a Basic Subscription Right, and an over-subscription privilege, or an Over-Subscription Privilege.  The Subscription Rights will not be tradable.

Every                 Basic Subscription Rights will entitle you to purchase one share of our common stock, at a subscription price per share of $                , or the Subscription Price.  If you exercise your Basic Subscription Rights in full, and any portion of the shares of our common stock remain available under the Rights Offering, you will be entitled to an Over-Subscription Privilege to purchase a portion of the unsubscribed shares of our common stock at the Subscription Price, subject to proration and ownership limitations.

The Subscription Rights will expire if they are not exercised by 5:00 p.m., Eastern Time, on December 13, 2019, or the Expiration Date, unless the Rights Offering is extended or earlier terminated by us.  If we elect to extend the Rights Offering, we will issue a press release announcing the extension no later than 9:00 a.m., Eastern Time, on the next business day after the most recently announced expiration date of the Rights Offering.  We may extend the Rights Offering for additional periods in our sole discretion.  Once made, except as otherwise set forth in this prospectus supplement, all exercises of Subscription Rights are irrevocable.

We have not entered into any standby purchase agreement or other similar arrangement in connection with the Rights Offering.  The Rights Offering is being conducted on a best-efforts basis and there is no minimum amount of proceeds necessary to be received in order for us to close the Rights Offering.

We are offering the shares of our common stock through the Rights Offering directly without the services of an underwriter or selling agent.  As such, we will not incur any investment banking fees or expenses in connection with the Rights Offering.

Consistent with our past practice, we currently anticipate declaring a dividend distribution on our common stock in the fourth quarter of 2019.  To the extent any shares of our common stock to be issued in the Rights Offering have been issued and are outstanding on the record date for such dividend distribution, such shares of common stock will participate in the dividend distribution.

Shares of our common stock are, with certain exceptions, subject to a 9.8% ownership limitation to, among other purposes, assist us in qualifying and maintaining our qualification as a real estate investment trust, or REIT.  In addition, our charter contains various other restrictions on the ownership and transfer of shares of our common stock.  See “Description of Securities—Restrictions on Ownership and Transfer” beginning on page 23 of the accompanying base prospectus.

Investing in our securities involves a high degree of risk.  See the section entitled “Risk Factors” beginning on page S-17 of this prospectus supplement and page 3 of the accompanying base prospectus.  You should carefully consider these risk factors, as well as the information contained in this prospectus supplement and the accompanying base prospectus, before you invest.

Computershare Trust Company, N.A. will serve as the Subscription Agent for the Rights Offering.  The Subscription Agent will hold the funds we receive from subscribers until we complete, abandon or terminate the Rights Offering.  If you want to participate in the Rights Offering and you are the record holder of your shares, we recommend that you submit your subscription documents to the Subscription Agent well before the deadline.  If you want to participate in the Rights Offering and you hold shares through your broker, dealer, bank or other nominee, you should promptly contact your broker, dealer, bank or other nominee and submit your subscription documents in accordance with the instructions and within the time period provided by your broker, dealer, bank or other nominee.  For a detailed discussion, see “The Rights Offering—The Subscription Rights.”

We reserve the right to terminate the Rights Offering for any reason any time before the closing of the Rights Offering.  If we terminate the Rights Offering, all subscription payments received will be returned as soon as practicable, without interest or deduction.  We expect the Rights Offering to expire on or about December 13, 2019, subject to our right to extend the Rights Offering as described above.  As soon as practicable after the Rights Offering has expired, payment for the shares of common stock subscribed for has cleared and all prorating calculations and reductions contemplated by the terms of the Rights Offering have been effected, we expect to close on subscriptions and for the Subscription Agent to arrange for the issuance of the shares of our common stock purchased in the Rights Offering.

Our common stock is listed on Nasdaq Stock Market, or NASDAQ, under the symbol “SELF.”  On October 18, 2019, the closing sale price of our common stock on NASDAQ was $4.59 per share.  The Subscription Rights are non-transferrable and will not be listed for trading on NASDAQ or any other securities exchange or market.  You are urged to obtain a current price quote for our common stock before exercising your Subscription Rights.

 

As of October 18, 2019, the aggregate market value of the outstanding shares of our common stock held by non-affiliates was approximately $32,801,265.  We have not sold any securities pursuant to General Instruction I.B.6. to Form S-3 during the prior 12 calendar month period ending on, and including, October 18, 2019.

If you have any questions or need further information about the Rights Offering, please call Georgeson LLC, our Information Agent for the Rights Offering, at (800) 213-0473 (toll-free).

Our board of directors is making no recommendation regarding your exercise of the Subscription Rights.  You should carefully consider whether to exercise your Subscription Rights before the Expiration Date.  Except as otherwise set forth in this prospectus supplement, you may not revoke or revise any exercises of Subscription Rights once made.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or passed upon the adequacy or accuracy of this prospectus supplement or the accompanying base prospectus.  Any representation to the contrary is a criminal offense.

The date of this prospectus supplement is              , 2019

This prospectus supplement and the accompanying base prospectus form a part of a registration statement on Form S-3 that we filed with the Securities and Exchange Commission, or the SEC, utilizing a “shelf” registration process.  This document is in two parts.  The first part is the prospectus supplement, which describes the specific terms of the Rights Offering.  The second part, the accompanying base prospectus, provides more general information about the securities we may offer from time to time, some of which may not apply to the securities offered by this prospectus supplement.  Generally, when we refer to this prospectus, we are referring to both parts of this document combined.  Before you invest, you should carefully read this prospectus supplement, the accompanying base prospectus, all information incorporated by reference herein and therein, and the additional information described under “Where You Can Find More Information” on page S-42 of this prospectus supplement.  These documents contain information you should consider when making your investment decision.  This prospectus supplement may add, update or change information contained in the accompanying base prospectus.  To the extent that any statement that we make in this prospectus supplement is inconsistent with statements made in the accompanying base prospectus or any documents incorporated by reference therein, the statements made in this prospectus supplement will be deemed to modify or supersede those made in the accompanying base prospectus and such documents incorporated by reference therein.

We have not authorized any other person to provide you with any information that is different.  We are offering to sell, and seeking offers to buy, our securities only in jurisdictions where offers and sales are permitted.  The distribution of this prospectus supplement and the accompanying base prospectus and the offering of the securities in certain jurisdictions may be restricted by law.  Persons outside the United States who come into possession of this prospectus supplement and/or the accompanying base prospectus must inform themselves about, and observe any restrictions relating to, the offering of the securities and the distribution of this prospectus supplement and/or the accompanying base prospectus outside the United States.  This prospectus supplement and the accompanying base prospectus do not constitute, and may not be used in connection with, an offer to sell, or a solicitation of an offer to buy, any securities offered by this prospectus supplement and the accompanying base prospectus by any person in any jurisdiction in which it is unlawful for such person to make such an offer or solicitation.

We further note that the representations, warranties and covenants made by us in any agreement that is filed as an exhibit to any document that is incorporated by reference in the accompanying base prospectus were made solely for the benefit of the parties to such agreement, including, in some cases, for the purpose of allocating risk among the parties to such agreements, and should not be deemed to be a representation, warranty or covenant being made to you.  Moreover, such representations, warranties or covenants were accurate only as of the date when made.  Accordingly, such representations, warranties and covenants should not be relied on as accurately representing the current state of our affairs.

QUESTIONS AND ANSWERS RELATING TO RIGHTS OFFERING

The following are examples of what we anticipate will be common questions about the Rights Offering.  The answers are based on selected information included elsewhere in this prospectus supplement.  The following questions and answers do not contain all of the information that may be important to you and may not address all of the questions that you may have about the Rights Offering.  This prospectus supplement and the accompanying base prospectus and the documents incorporated by reference herein and therein may contain more detailed descriptions of the terms and conditions of the Rights Offering and provide additional information about us and our business, including potential risks related to the Rights Offering, the shares of our common stock offered hereby, and our business.  We urge you to read the entirety of this prospectus supplement and the accompanying base prospectus and the documents incorporated by reference herein and therein before making an investment decision.

Why are we conducting the Rights Offering?

We are conducting the Rights Offering to raise capital that we intend to use to fund a portion of the purchase price of the West Henrietta Property and related expenses described below under “Prospectus Supplement Summary—Recent Developments—West Henrietta Property Acquisition” and/or to repay borrowings under our revolving credit facility.  We intend to use any remaining proceeds to fund acquisitions of other self storage properties, to fund expansions of our existing self storage properties, and for working capital and general corporate purposes.  See “Use of Proceeds.”  We believe that the Rights Offering will strengthen our financial condition by generating additional cash and increasing our stockholders’ equity.

What is the Rights Offering?

We are distributing, at no charge, to record holders of shares of our common stock who are entitled to participate in the Rights Offering, non-transferable Subscription Rights.  Each record holder of our common stock will receive one Subscription Right for every share of our common stock owned by such record holder as of 5:00 p.m., Eastern Time, on the Record Date.  Each Subscription Right consists of a Basic Subscription Right and an Over-Subscription Privilege.  The Subscription Rights will not be tradable.  The Subscription Rights will expire if they are not exercised by 5:00 p.m., Eastern Time, on the Expiration Date, unless we extend or earlier terminate the Rights Offering.

What are the Basic Subscription Rights?

You will receive one Basic Subscription Right for every share of our common stock that you owned as of 5:00 p.m., Eastern Time, on the Record Date.  The Basic Subscription Rights will entitle you to purchase one share of our common stock at a Subscription Price of $                 per share for each                  Basic Subscription Rights you hold.  Fractional shares of our common stock will not be issued upon the exercise of Basic Subscription Rights.  Accordingly, shares of our common stock may be purchased only pursuant to the exercise of Basic Subscription Rights in integral multiples of                 .  The total number of Basic Subscription Rights you receive will be rounded up to the nearest number of Subscription Rights evenly divisible by                 .

For example, if you owned                  shares of our common stock as of the Record Date, you will receive                  Basic Subscription Rights and will have the right to purchase                  shares of our common stock for an aggregate purchase price of $                 per share (or a total payment of $                ).  Alternatively, for example, if you owned                  shares of our common stock as of the Record Date, you will receive                 Basic Subscription Rights and will have the right to purchase                  shares of our common stock for an aggregate purchase price of $                 per share (or a total payment of $                ).  You may exercise all or a portion of your Basic Subscription Rights or you may choose not to exercise any Basic Subscription Rights at all.

If you are a record holder of our common stock, the number of shares you may purchase pursuant to your Basic Subscription Rights is indicated on the enclosed Rights Certificate.  If you hold your shares in the name of a broker, dealer, bank or other nominee who uses the services of The Depository Trust Company, or DTC, you will not receive a Rights Certificate.  Instead, DTC will issue the Basic Subscription Rights to your nominee record holder for each share of our common stock that you beneficially own as of the Record Date.  If you are not contacted by your nominee, you should contact your nominee as soon as possible.

What is the Over-Subscription Privilege?

If you exercise your Basic Subscription Rights in full, you may also choose to exercise your Over-Subscription Privilege to purchase shares of our common stock that remain available under the Rights Offering.  You should indicate on your Rights Certificate, or the form provided by your nominee if your shares are held in the name of a nominee, how many additional shares of our common stock you would like to purchase pursuant to your Over-Subscription Privilege, or your Over-Subscription Request.

Subject to stock ownership limitations, if sufficient shares of our common stock are available, we will seek to honor your Over-Subscription Request in full.  If Over-Subscription Requests exceed the available number of shares, however, we will allocate the available shares of our common stock pro-rata among the record holders exercising the Over-Subscription Privilege in proportion to the number of shares of our common stock each of those record holders owned on the Record Date, relative to the number of shares of our common stock owned on the Record Date by all record holders exercising the Over-Subscription Privilege.  If this pro-rata allocation results in any record holders receiving a greater number of shares of our common stock than the record holder subscribed for pursuant to the exercise of the Over-Subscription Privilege, then such record holder will be allocated only that number of shares of our common stock for which the record holder oversubscribed, and the remaining shares of our common stock will be allocated among all other record holders exercising the Over-Subscription Privilege on the same pro rata basis described above.  The proration process will be repeated until all available shares of our common stock have been allocated.  See “The Rights Offering—Limitation on the Purchase of Shares of our Common Stock” for a description of certain stock ownership limitations.

To properly exercise your Over-Subscription Privilege, you must deliver to the Subscription Agent the subscription payment related to your Over-Subscription Privilege before the Rights Offering expires.  See “The Rights Offering—The Subscription Rights—Over-Subscription Privilege.”  If you are exercising your Over-Subscription Privilege through your broker, dealer, bank or other nominee, you should promptly contact your broker, dealer, bank or other nominee and deliver the subscription payment related to your Over-Subscription Privilege in accordance with the instructions and within the time period provided by your broker, dealer, bank or other nominee.  To the extent you properly exercise your Over-Subscription Privilege for an amount of shares of our common stock that exceeds the number of unsubscribed shares of our common stock available to you, any excess subscription payments will be returned to you as soon as practicable after the Rights Offering has expired, without interest or deduction.

Computershare Trust Company, N.A., our Subscription Agent for the Rights Offering, will determine the allocation of Over-Subscription Requests as described above.

May the Subscription Rights that I exercise be reduced for any reason?

Yes.  To assist us in complying with the limitations on the concentration of ownership applicable to REITs, among other purposes, our charter provides that, subject to certain exceptions, no person or entity may own, or be deemed to own, by virtue of the applicable constructive ownership provisions of the Internal Revenue Code of 1986, as amended, or the Code, more than 9.8% in value or in number, whichever is more restrictive, of the outstanding shares of our common stock, or 9.8% in value or in number, whichever is more restrictive, of the outstanding shares of all classes and series of our capital stock.  Accordingly, the Basic Subscription Rights are subject to the limitation that no Basic Subscription Rights (including Over-Subscription Privileges) may be exercised if such exercise would result in the holder receiving shares of our common stock in violation of the ownership limits contained in our charter.  Any purported exercise of Basic Subscription Rights or Over-Subscription Privilege, and any delivery of shares of common stock upon a purported exercise, shall be void to the extent (but only to the extent) that such exercise and the receipt of common stock by the holder would result in such holder violating these ownership limitations.  See “Description of Securities—Restrictions on Ownership and Transfer” beginning on page 23 of the accompanying prospectus for more information about these restrictions.

Please also see the discussion under “The Rights Offering—The Subscription Rights—Over-Subscription Privilege” for a description of the potential proration as to the Over-Subscription Privilege.

If the amount of shares allocated to you is less than your subscription request, then the excess funds held by the Subscription Agent on your behalf will be returned to you, without interest, as soon as practicable after the

Rights Offering has expired and all prorating calculations and reductions contemplated by the terms of the Rights Offering have been effected, and we will have no further obligations to you.

Will fractional shares be issued upon exercise of Subscription Rights or upon the issuance of the shares of our common stock?

No.  The Basic Subscription Rights will entitle you to purchase one share of our common stock at a Subscription Price of $                 per share for each                  Basic Subscription Rights you hold.  Fractional shares of our common stock will not be issued upon the exercise of Basic Subscription Rights.  Accordingly, shares of our common stock may be purchased only pursuant to the exercise of Basic Subscription Rights in integral multiples of                 .  The total number of Basic Subscription Rights you receive will be rounded up to the nearest number of Subscription Rights evenly divisible by                 .  Any excess subscription payments received by the Subscription Agent will be returned as soon as practicable after the Rights Offering has expired, without interest or deduction.

What effect will the Rights Offering have on our outstanding common stock?

Assuming no other transactions by us involving our capital stock prior to the expiration of the Rights Offering, and if the Rights Offering is fully subscribed, upon consummation of the Rights Offering we will have                  shares of our common stock issued and outstanding, based on 7,729,006 shares of our common stock outstanding as of October 18, 2019.  The exact number of shares of our common stock that we will issue in the Rights Offering will depend on the number of shares of our common stock that are subscribed for in the Rights Offering.

How was the Subscription Price determined?

In determining the Subscription Price, our board of directors considered, among other things, the following factors:

·	our need to raise capital in order to grow our business;

·	the current and historical trading prices of our common stock;

·	the price at which stockholders might be willing to participate in the Rights Offering;

·	our need for additional capital and liquidity;

·	the cost of capital from other sources; and

·	comparable precedent transactions, including the percentage of shares offered, the terms of the subscription rights being offered, the subscription price and the discount that the subscription price represented to the immediately prevailing closing prices for those offerings.

In conjunction with the review of these factors, our board of directors also reviewed our history and prospects, including our past and present earnings and cash requirements, our prospects for the future, the outlook for our industry and our current financial condition.  Our board of directors also believed that the Subscription Price should be designed to provide an incentive to our current stockholders to participate in the Rights Offering and exercise their Basic Subscription Right and their Over-Subscription Privilege.

The Subscription Price does not necessarily bear any relationship to any established criteria for value.  You should not consider the Subscription Price as an indication of actual value of our company or our common stock.  The market price of our common stock may decline during or after the Rights Offering.  You should obtain a current price quote for our common stock and perform an independent assessment of our common stock before exercising your Subscription Rights and make your own assessment of our business and financial condition, our prospects for the future, the terms of the Rights Offering, the information in this prospectus and the other considerations relevant to your circumstances.  Once made, except as otherwise set forth in this prospectus supplement, all exercises of Subscription Rights are irrevocable.

Am I required to exercise all of the Basic Subscription Rights I receive in the Rights Offering?

No.  You may exercise any number of your Basic Subscription Rights, or you may choose not to exercise any Basic Subscription Rights.  If you do not exercise any Basic Subscription Rights, the number of shares of our common stock you own will not change.  However, if you choose to not exercise your Basic Subscription Rights in full and other holders of Subscription Rights do exercise, your proportionate ownership interest in our company will decrease.  If you do not exercise your Basic Subscription Rights in full, you will not be entitled to exercise your Over-Subscription Privilege.

How soon must I act to exercise my Subscription Rights?

If you received a Rights Certificate and elect to exercise any or all of your Subscription Rights, the Subscription Agent must receive your completed and signed Rights Certificate and payment for both your Basic Subscription Rights and any Over-Subscription Privilege you elect to exercise before 5:00 p.m., Eastern Time, on the Expiration Date, unless we extend or earlier terminate the Rights Offering.  If you hold your shares in the name of a broker, dealer, bank or other nominee, your nominee may establish a deadline before the expiration of the Rights Offering by which you must provide it with your instructions to exercise your Subscription Rights, along with the required subscription payment.

May I transfer my Subscription Rights?

No.  The Subscription Rights may be exercised only by the stockholders to whom they are distributed, and they may not be sold, transferred, assigned or given away to anyone else, other than by operation of law.  As a result, Rights Certificates may be completed only by the holder who receives the certificate.  We do not intend to apply for the listing of the Subscription Rights on any securities exchange or recognized trading market.

Will our directors, executive officers and affiliates participate in the Rights Offering?

To the extent our directors, executive officers and affiliates hold common stock as of the Record Date, they will be entitled to participate in the Rights Offering on the same terms and conditions applicable to other Subscription Rights holders.  While none of our directors or executive officers has entered into any binding commitment or agreement to exercise Subscription Rights received in the Rights Offering, all of our directors and executive officers have indicated an interest in participating in the Rights Offering.

Has our board of directors made a recommendation to stockholders regarding the Rights Offering?

No.  Our board of directors is making no recommendation regarding your exercise of the Subscription Rights.  Subscription Rights holders who exercise Subscription Rights will incur investment risk on new money invested.  Our common stock is listed on NASDAQ.  We cannot predict the price at which our shares of our common stock will trade after the Rights Offering.  On October 18, 2019, the last reported sale price of our common stock on NASDAQ was $4.59 per share.  You should make your decision based on your assessment of our business and financial condition, our prospects for the future, the terms of the Rights Offering, the information contained in this prospectus and other considerations relevant to your circumstances.  See “Risk Factors” for discussion of some of the risks involved in investing in our securities.

How do I exercise my Subscription Rights?

If you are a stockholder of record (meaning you hold your shares of our common stock in your name and not through a broker, dealer, bank or other nominee) and you wish to participate in the Rights Offering, you must deliver a properly completed and signed Rights Certificate, together with payment of the Subscription Price for both your Basic Subscription Rights and any Over-Subscription Privilege you elect to exercise, to the Subscription Agent before 5:00 p.m., Eastern Time, on the Expiration Date.  If you are exercising your Subscription Rights through your broker, dealer, bank or other nominee, you should promptly contact your broker, dealer, bank or other nominee and submit your subscription documents and payment for the shares of our common stock subscribed for in accordance with the instructions and within the time period provided by your broker, dealer, bank or other nominee.

What if my shares are held in “street name”?

If you hold your shares of our common stock in the name of a broker, dealer, bank or other nominee, then your broker, dealer, bank or other nominee is the record holder of the shares you beneficially own.  The record holder must exercise the Subscription Rights on your behalf.  Therefore, you will need to have your record holder act for you.

If you wish to participate in the Rights Offering and purchase shares of our common stock, please promptly contact the record holder of your shares.  We will ask the record holder of your shares, who may be your broker, dealer, bank or other nominee, to notify you of the Rights Offering.

What form of payment is required?

You must timely pay the full Subscription Price for the full number of shares of our common stock you wish to acquire pursuant to the exercise of Subscription Rights by delivering to the Subscription Agent a personal check drawn on a U.S. bank.

If you send payment by personal uncertified check, payment will not be deemed to have been delivered to the Subscription Agent until the check has cleared.  As such, any payments made by personal check should be delivered to the Subscription Agent no fewer than three business days prior to the Expiration Date.

If you send a payment that is insufficient to purchase the number of shares of our common stock you requested, or if the number of shares of our common stock you requested is not specified in the forms, the payment received will be applied to exercise your Subscription Rights to the fullest extent possible based on the amount of the payment received.

When will I receive my new shares of our common stock?

As soon as practicable after the Rights Offering has expired, payment for the shares of common stock subscribed for has cleared and all prorating calculations and reductions contemplated by the terms of the Rights Offering have been effected, we expect to close on subscriptions and for the Subscription Agent to arrange for the issuance of the shares of our common stock purchased in the Rights Offering.  All shares that you purchase in the Rights Offering will be issued in book-entry, or uncertificated, form meaning that you will receive a direct registration, or DRS, account statement from our transfer agent reflecting ownership of these securities if you are a holder of record of shares.  If you hold your shares in the name of a broker, dealer, bank or other nominee, DTC will credit your account with your nominee with the securities you purchase in the Rights Offering.

After I send in my payment and Rights Certificate to the Subscription Agent, may I cancel my exercise of Subscription Rights?

No.  Exercises of Subscription Rights are irrevocable, even if you later learn information that you consider to be unfavorable to the exercise of your Subscription Rights.  However, if we make a material change to the terms of the Rights Offering set forth in this prospectus supplement, for example, extending the Rights Offering beyond the Expiration Date as permitted in this prospectus supplement or materially increasing or decreasing the Subscription Price, or a Material Change, you may cancel your subscription and receive a refund of any money you have advanced. You should not exercise your Subscription Rights unless you are certain that you wish to purchase shares of our common stock at the Subscription Price.

How much will we receive from the Rights Offering?

Assuming that the Rights Offering is fully subscribed, we estimate that the net proceeds from the Rights Offering will be approximately $11,224,500, based on the Subscription Price of $                per share.  We intend to use a portion of the net proceeds from the Rights Offering to fund the purchase price of the West Henrietta Property and related expenses described below under “Prospectus Supplement Summary—Recent Developments—West Henrietta Property Acquisition” and/or repay borrowings under our revolving credit facility. We intend to use any remaining proceeds to fund acquisitions of other self storage properties, to fund expansions of our existing self storage properties, and for working capital and general corporate purposes.

Are there risks in exercising my Subscription Rights?

Yes.  The exercise of your Subscription Rights involves risks.  Exercising your Subscription Rights involves the purchase of shares of our common stock and you should consider this investment as carefully as you would consider any other investment.

Can we terminate, extend or amend the Rights Offering?

Yes.  We may decide to terminate the Rights Offering at any time and for any reason before the expiration of the Rights Offering.  We also have the right to extend the Rights Offering for additional periods or to otherwise amend or modify the terms of the Rights Offering in our sole discretion.  However, if we make a Material Change, we will circulate an updated prospectus supplement reflecting the modified terms in advance of 5:00 p.m., Eastern Time, on the Expiration Date, unless extended, and you may cancel your subscription and receive a refund of any money you have advanced.  In addition, upon such event, we may extend the Expiration Date to allow holders of Rights ample time to make new investment decisions and for us to circulate updated documentation.

We will notify stockholders and the public if the Rights Offering is terminated or extended by issuing a press release announcing such event no later than 9:00 a.m., Eastern Time, on the next business day after the most recently announced expiration date of the Rights Offering.

If the Rights Offering is not completed or is terminated, will my subscription payment be refunded to me?

Yes.  The Subscription Agent will hold all funds it receives in a segregated bank account until completion of the Rights Offering.  If we do not complete the Rights Offering, all subscription payments received by the Subscription Agent will be returned as soon as practicable after the Rights Offering has expired or has been terminated, without interest or deduction.  If you own shares in “street name,” it may take longer for you to receive your subscription payment because the Subscription Agent will return payments through the record holder of your shares.

How do I exercise my Rights if I live outside the United States?

The Subscription Agent will hold Rights Certificates for stockholders having addresses outside the United States.  To exercise Subscription Rights, foreign holders must notify the Information Agent and timely follow other procedures described in the section entitled “The Rights Offering—Foreign Holders.”

What fees or charges apply if I purchase shares in the Rights Offering?

We are not charging any fee or sales commission to issue Subscription Rights to you or to issue shares of our common stock to you if you exercise your Subscription Rights.  If you exercise your Subscription Rights through a broker, dealer, bank or other nominee, you are responsible for paying any fees your broker, dealer, bank or other nominee may charge you.

What are the U.S. federal income tax consequences of receiving and/or exercising my Subscription Rights?

For U.S. federal income tax purposes, we do not believe you should recognize income or loss in connection with the receipt or exercise of Subscription Rights in the Rights Offering.  You should consult your tax advisor as to the tax consequences of the Rights Offering in light of your particular circumstances.  For a detailed discussion, see “Additional U.S. Federal Income Tax Consequences.”

To whom should I send my forms and payment?

If your shares are held in the name of a broker, dealer, bank or other nominee, then you should send your subscription documents and subscription payment to that broker, dealer, bank or other nominee.  If you are the record holder, then you should send your subscription documents, Rights Certificate and subscription payment to the Subscription Agent by first class mail or courier service to:

By mail:		By overnight courier:
Corporate Actions Voluntary Offer P.O. Box 43011 Providence, RI 02940-3011		Corporate Actions Voluntary Offer 150 Royall Street, Suite V Canton, MA 02021

Global Self Storage, Inc., a Maryland corporation, is a self-administered and self-managed REIT that owns, operates, manages, acquires, develops and redevelops self storage properties in the United States.  Our properties are designed to offer affordable, easily accessible, and secure storage space for residential and commercial customers.  We currently own and operate 11 self storage properties located in Connecticut, Illinois, Indiana, New York, Ohio, Pennsylvania, and South Carolina.  We were incorporated on December 12, 1996 under the laws of the state of Maryland.  We have elected and we believe we have qualified to be taxed as a REIT for U.S. federal income tax purposes commencing with our taxable year ended December 31, 2013.  To the extent we continue to qualify as a REIT, we will not generally be subject to U.S. federal income tax, with certain limited exceptions, on our taxable income that is distributed to our stockholders.

We were originally formed in September 1983 as a diversified series of shares of Bull & Bear Incorporated, an open-end management investment company.  On February 7, 1997, we commenced operations as a closed-end management investment company registered under the Investment Company Act of 1940, as amended, or the Investment Company Act.  On February 29, 2012, our stockholders approved a proposal to transition our business from an investment company to a self storage operating company.  On January 19, 2016, we changed our name to Global Self Storage, Inc. from Self Storage Group, Inc., changed our SEC registration from an investment company to an operating company reporting under the Securities Exchange Act of 1934, as amended, or the Exchange Act, and listed our common stock on NASDAQ under the symbol “SELF.”

Our Portfolio

As of June 30, 2019, our current portfolio consisted of 11 self storage properties with an aggregate of 766,923 net leasable square feet and 5,613 storage units, as described below.  In addition to traditional and climate-controlled units, many of the properties feature both covered and outside auto/RV/boat storage.

Our properties are generally located in densely populated and high traffic areas near major roads and highways.  All of our properties display prominent road signage and most feature LED marquee boards describing the property features and move-in rent specials.  Our properties are generally located in areas with strict zoning laws and attentive planning boards which make it difficult for our competition to develop new properties near ours.

In seeking to maximize the performance of our properties, we employ our proprietary revenue rate management systems which help us to analyze, adjust, and set our move-in and existing tenant rental rates on a real-time basis across our portfolio of properties.  Among other technologies, we employ internet data scraping of our local competitors’ move-in rental rates to help enable us to proactively respond and take advantage of changing market conditions across our portfolio.  Our operating results typically depend significantly on our ability to manage our property units’ rental rates, to respond in a timely manner to prospective tenant inquiries, and to lease available property units, and on the ability of our tenants to make required storage unit rental payments.

We have registered the trademark and developed the brand “Global Self Storage.”  We have developed a corporate logo and have incorporated it on all of our on-site signage, advertising and other marketing materials.  This branding process has included the creation and development of the www.GlobalSelfStorage.us website, whereby prospective customers can rent a storage unit or learn about the features of any of our properties in their various locations.  We continue to develop the Global Self Storage internet presence through advertising and search engine optimization.  We solicit tenant reviews for posting to the “Testimonials” section of our website and encourage others to view these reviews.  We have found that a reliable source of new tenants is through referrals of current tenants.  Existing self storage customers may also pay their storage unit rent online through www.GlobalSelfStorage.us.

Attracting high quality, long-term tenants is a top priority for us and we strongly believe in tenant quality over tenant quantity.  In our marketing efforts, we have seen success in our referral marketing program, through which our tenants may recommend Global Self Storage to their family, friends, and colleagues.  We also believe our property

managers’ attention to detail – maintaining security, cleanliness, and attentive customer service – is essential to attracting high quality tenants.

Each of our properties features a rental and payment center kiosk available 24 hours a day, seven days a week, where prospective tenants can rent a unit and current tenants can pay their rent.  All of our properties have on-site property managers who are committed to delivering the finest customer service.  We utilize a customer call center to handle telephone inquiries from current and prospective tenants whenever our store managers are not available.  They can respond to questions about our properties and storage features, and book reservations.  We seek to deliver convenience and high quality customer service to our tenants, as well as maintain clean and secure properties at all times.

Our Acquisition Strategy

In our store acquisition strategy, we will seek to continue to focus on secondary and tertiary cities in the Mid-West, Northeast and Mid-Atlantic parts of the country where we believe there is relatively less self storage space per capita available, generally resulting in greater demand for available self storage square feet; where new self storage development and permitting through the local planning and zoning boards is typically more difficult to secure thus creating barriers to entry for new self storage competition; and where local new supply through new development is generally less prevalent.

We continue to review available acquisition opportunities with the awareness that, should interest rates increase, resulting store capitalization rates may also increase and store prices may begin to decrease.  We will seek to continue to employ our strict acquisition underwriting standards and remain a disciplined buyer and only execute acquisitions where we believe that our management techniques and innovations can strengthen our portfolio and increase stockholder value.  For future acquisitions, we may use various financing and capital raising alternatives including, but not limited to, debt and/or equity offerings (including the net proceeds from the Rights Offering), credit facilities, mortgage financing, and joint ventures with third parties.  See “—Recent Developments—West Henrietta Property Acquisition.”

We may pursue third-party management opportunities, which may include managing properties owned by certain affiliates or joint venture partners for a fee, and utilize such relationships with third-party owners as a source for future acquisitions and investment opportunities.  See “—Recent Developments—Edmond Property Third-Party Management.”

Our Financing Strategy

Our financing strategy is to minimize the cost of our capital in order to maximize the returns generated for our stockholders.  On June 24, 2016, certain of our wholly owned subsidiaries, or Secured Subsidiaries, entered into a loan agreement and certain other related agreements, or the Loan Agreement, between the Secured Subsidiaries and Insurance Strategy Funding IV, LLC, or the Lender.  Under the Loan Agreement, the Secured Subsidiaries borrowed from Lender the principal amount of $20 million pursuant to a promissory note, or the Promissory Note.  The Promissory Note bears interest at a rate equal to 4.192% per annum and is due to mature on July 1, 2036. 

Pursuant to a security agreement, or the Security Agreement, the obligations under the Loan Agreement are secured by certain real estate assets owned by the Secured Subsidiaries.  J.P. Morgan Investment Management, Inc. acted as Special Purpose Vehicle Agent of the Lender.  We entered into a non-recourse guaranty, or the Guaranty, and together with the Loan Agreement, the Promissory Note and the Security Agreement, or the Loan Documents, on June 24, 2016 to guarantee the payment to Lender of certain obligations of the Secured Subsidiaries under the Loan Agreement.  We have used some of the proceeds from the Loan Agreement to acquire four additional self storage properties.

On December 20, 2018, certain of our wholly owned subsidiaries entered into a revolving credit loan agreement, or our revolving credit facility.  Under our revolving credit facility, certain of our subsidiaries may borrow from the lender in the principal amount of up to $10 million.  Borrowings under our revolving credit facility bear interest at a rate equal to 3.00% over the One Month U.S. Dollar London Inter-Bank Offered Rate and our revolving credit facility is due to mature on December 20, 2021.  The obligations under our revolving credit facility are secured by certain real estate assets owned by certain of our subsidiaries and are guaranteed by us.

Recent Developments

West Henrietta Property Acquisition

On October 4, 2019, we, through a wholly owned subsidiary, entered into an agreement with Erie Station Storage, LLC, to acquire a self storage property located in West Henrietta, New York, or the West Henrietta Property, for the sum of approximately $6.2 million.

Below is a summary of key information regarding the West Henrietta Property:

We intend to use the net proceeds from the Rights Offering to fund a portion of the purchase price of the West Henrietta Property and related expenses and/or to repay borrowings under our revolving credit facility.  We intend to use any remaining proceeds to fund acquisitions of other self storage properties, to fund expansions of our existing self storage properties, and for working capital and general corporate purposes.  See “Use of Proceeds.”  The closing of the Rights Offering is not conditioned on the closing of the West Henrietta Property.  See the risk factors below titled “We may fail to consummate the acquisition of the West Henrietta Property, which could have a material adverse impact on our financial condition and results of operations” and “We may not acquire the West Henrietta Property and the closing of the Rights Offering is not conditioned on the closing of the West Henrietta Property.”

Edmond Property Third-Party Management

On October 23, 2019, we signed our first self storage client under our new third-party management platform.  The 134,318-leasable square foot property, which will be rebranded as “Global Self Storage,” is comprised of 618 climate-controlled and non-climate-controlled units located in Edmond, Oklahoma.

We believe that our third-party management platform will provide an additional revenue stream through management fees and tenant insurance premiums and will help expand our brand awareness, and may also allow us to build a captive acquisition pipeline.  We are actively marketing our third-party management platform to

developers, single-property self storage operators, and small-portfolio self storage operators, and we believe these discussions may lead to the addition of new properties to our owned and/or third-party management portfolios.

Corporate Information

Our principal corporate offices are located at 11 Hanover Square, New York, New York 10005.  Our telephone number is (212) 785-0900.  Our website is www.globalselfstorage.us.  The information on our website is not intended to form a part of or be incorporated by reference into this prospectus supplement or the accompanying base prospectus.

Summary of the Rights Offering

Investing in our securities involves a high degree of risk.  Before making an investment decision, you should carefully consider the following risk factors and the risk factors described in the periodic reports which we file with the SEC, as well as risk factors and other information in this prospectus supplement and the accompanying base prospectus (including the documents incorporated by reference herein and therein) or any free writing prospectus before purchasing any of our securities.  Any of these risks described could materially adversely affect our business, financial condition, results of operations, tax status or ability to make distributions to our stockholders.  Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial may also materially and adversely affect our business operations.  If this were to happen, the price of our securities could decline significantly, and you could lose a part or all of your investment.  See “Where You Can Find More Information” beginning on page S-42 of this prospectus supplement.

Risks Related to the West Henrietta Property Acquisition

Risks Related to the Rights Offering

Your interest in our company may be diluted as a result of the Rights Offering.

Holders who do not fully exercise their Subscription Rights should expect that they will, at the completion of the Rights Offering, own a smaller proportional interest in our company than would otherwise be the case had they fully exercised their Subscription Rights.  Further, if you purchase shares of our common stock in the Rights Offering at the Subscription Price, you may suffer immediate and substantial dilution in the net tangible book value of our common stock.  See “Dilution” in this prospectus supplement for a more detailed discussion of the dilution which may incur in connection with the Rights Offering.

Completion of the Rights Offering is not subject to us raising a minimum offering amount.

Completion of the Rights Offering is not subject to us raising a minimum offering amount and, therefore, proceeds may be insufficient to meet our objectives, thereby increasing the risk to investors in the Rights Offering, including investing in a company that continues to require capital.  See “Use of Proceeds.”

The Rights Offering may cause the trading price of our common stock to decrease.

The Subscription Price, together with the number of shares of our common stock we propose to issue and ultimately will issue if the Rights Offering is completed, may result in an immediate decrease in the market price of our common stock.  This decrease may continue after the completion of the Rights Offering.  If that occurs, you may have committed to buy shares of our common stock at a price greater than the prevailing market price.  Further, if a substantial number of Subscription Rights are exercised and the holders of the shares received upon exercise of those Subscription Rights choose to sell some or all of the shares underlying the Subscription Rights, the resulting sales could depress the market price of our common stock.

Because the exercise of your Subscription Rights is not revocable, you could be committed to buying shares of our common stock above the prevailing market price.

Once you exercise your Subscription Rights, except as otherwise set forth in this prospectus supplement, you may not revoke such exercise even if you later learn information that you consider to be unfavorable to the exercise of your Subscription Rights.  The market price of our shares of our common stock may decline prior to the expiration of the Rights Offering or a subscribing Subscription Rights holder may not be able to sell shares of our common stock purchased in the Rights Offering at a price equal to or greater than the Subscription Price.  Until shares of our common stock are delivered upon expiration of the Rights Offering, you will not be able to sell or transfer the shares of our common stock that you purchase in the Rights Offering.  Any such delivery will occur as soon as practicable after the Rights Offering has expired, payment for the shares of our common stock has cleared and all prorating calculations and reductions contemplated by the terms of the Rights Offering have been effected.

If we terminate the Rights Offering for any reason, we will have no obligation other than to return subscription monies as soon as practicable.

We may decide, in our sole discretion and for any reason, to cancel or terminate the Rights Offering at any time prior to the Expiration Date.  If the Rights Offering is cancelled or terminated, we will have no obligation with respect to Subscription Rights that have been exercised except to return as soon as practicable, without interest or deduction, all subscription payments deposited with the Subscription Agent.  If we terminate the Rights Offering and you have not exercised any Subscription Rights, such Subscription Rights will expire and be worthless.

Because we do not have any formal commitments from any of our stockholders to participate in the Rights Offering, the net proceeds we receive from the Rights Offering may be lower than we currently anticipate.

We do not have any formal commitments from any of our stockholders to participate in the Rights Offering, and we cannot assure you that any of our stockholders will exercise all or any part of their Basic Subscription Rights or their Over-Subscription Privilege.  If our holders subscribe for fewer shares of our common stock than we currently anticipate, the net proceeds we receive from the Rights Offering could be significantly lower than we currently expect.

The Subscription Price determined for the Rights Offering is not an indication of the fair value of our common stock.

In determining the Subscription Price, our board of directors considered a number of factors, including, but not limited to, our need to raise capital in order to grow our business, the current and historical trading prices of our common stock, a price that would increase the likelihood of participation in the Rights Offering, the cost of capital from other sources, comparable precedent transactions, an analysis of stock price trading multiples for companies similar to us.  The Subscription Price does not necessarily bear any relationship to any established criteria for value.  No valuation consultant or investment banker has opined upon the fairness or adequacy of the Subscription Price.  You should not consider the Subscription Price as an indication of the value of our company or our common stock.

If you do not act on a timely basis and follow subscription instructions, your exercise of Subscription Rights may be rejected.

Holders of Subscription Rights who desire to purchase shares of our common stock in the Rights Offering must act on a timely basis to ensure that all required forms and payments are actually received by the Subscription Agent prior to 5:00 p.m., New York City time, on the Expiration Date, unless extended.  If you are a beneficial owner of shares of our common stock and you wish to exercise your Subscription Rights, you must act promptly to ensure that your broker, dealer, bank, trustee or other nominee acts for you and that all required forms and payments are actually received by your broker, dealer, bank, trustee or other nominee in sufficient time to deliver such forms and payments to the Subscription Agent to exercise the Subscription Rights granted in the Rights Offering that you beneficially own prior to 5:00 p.m., New York City time on the Expiration Date, as may be extended.  We will not be responsible if your broker, dealer, bank, trustee or other nominee fails to ensure that all required forms and payments are actually received by the Subscription Agent prior to 5:00 p.m., New York City time, on the Expiration Date.

If you fail to complete and sign the required subscription forms, send an incorrect payment amount, or otherwise fail to follow the subscription procedures that apply to your exercise in the Rights Offering, the Subscription Agent may, depending on the circumstances, reject your subscription or accept it only to the extent of the payment received.  Neither we nor the Subscription Agent undertakes to contact you concerning an incomplete or incorrect subscription form or payment, nor are we under any obligation to correct such forms or payment.  We have the sole discretion to determine whether a subscription exercise properly follows the subscription procedures.

You may not receive all of the shares of our common stock for which you subscribe.

If excess shares of our common stock are available after the exercise of Basic Subscription Rights, holders who fully exercise their Basic Subscription Rights will be entitled to subscribe for an additional number of shares of our common stock.  Subject to stock ownership limitations, if sufficient shares of our common stock are available, we will seek to honor your Over-Subscription Request in full.  If Over-Subscription Requests exceed the available number of shares, however, we will allocate the available shares of our common stock pro-rata among the record holders exercising the Over-Subscription Privilege in proportion to the number of shares of our common stock each of those record holders owned on the Record Date, relative to the number of shares of our common stock owned on the Record Date by all record holders exercising the Over-Subscription Privilege.  Over-Subscription Privileges will be allocated pro rata among Subscription Rights holders who over-subscribed, based on the number of over-subscription shares of our common stock to which they have subscribed.

To assist us in complying with the limitations on the concentration of ownership applicable to REITs, among other purposes, our charter provides that, subject to certain exceptions, no person or entity may own, or be deemed to own, by virtue of the applicable constructive ownership provisions of the Code, more than 9.8% in value or in number, whichever is more restrictive, of the outstanding shares of our common stock, or 9.8% in value or in number, whichever is more restrictive, of the outstanding shares of all classes and series of our capital stock.  Accordingly, the Basic Subscription Rights are subject to the limitation that no Basic Subscription Rights (including Over-Subscription Privileges) may be exercised if such exercise would result in the holder receiving shares of our common stock in violation of the ownership limits contained in our charter.  Any purported exercise of Basic Subscription Rights or Over-Subscription Privilege, and any delivery of shares of common stock upon a purported exercise, shall be void to the extent (but only to the extent) that such exercise and the receipt of common stock by the holder would result in such holder violating these ownership limitations.  See “Description of Securities—Restrictions on Ownership and Transfer” beginning on page 23 of the accompanying base prospectus for more information about these restrictions.

We cannot guarantee that you will receive any or the entire amount of shares of our common stock for which you subscribed.  If for any reason the amount of shares of our common stock allocated to you is less than you have subscribed for, then the excess funds held by the Subscription Agent on your behalf will be returned to you, without interest, as soon as practicable after the Rights Offering has expired and all prorating calculations and reductions contemplated by the terms of the Rights Offering have been effected, and we will have no further obligations to you.

If you make payment of the Subscription Price by personal check, your check may not clear in sufficient time to enable you to purchase shares in the Rights Offering.

Any personal check used to pay for shares to be issued in the Rights Offering must clear prior to the Expiration Date of the Rights Offering, and the clearing process may require five or more business days.  If you choose to exercise your Subscription Rights, in whole or in part, and to pay for shares by personal check and your check has not cleared prior to the Expiration Date of the Rights Offering, you will not have satisfied the conditions to exercise your Subscription Rights and will not receive the shares you wish to purchase.

The receipt of Subscription Rights may be treated as a taxable distribution to you.

We believe the distribution of the Subscription Rights in the Rights Offering should be a non-taxable distribution to holders of shares of our common stock under Section 305(a) of the Code.  Please see the discussion on the “Additional U.S. Federal Income Tax Consequences” below.  However, this position is not binding on the Internal Revenue Service, or the IRS, or the courts.  If the Rights Offering is deemed to be part of a “disproportionate distribution” under Section 305 of the Code, your receipt of Subscription Rights in the Rights Offering may be treated as the receipt of a taxable distribution to you equal to the fair market value of the Subscription Rights.  Any such distribution would be treated as dividend income to the extent of our current and accumulated earnings and profits, if any, with any excess being treated as a return of capital to the extent of the recipient stockholder’s tax basis in our shares, and then as capital gain.  Each holder of shares of our common stock is urged to consult his, her or its own tax advisor with respect to the tax consequences of the Rights Offering.

Exercising the Subscription Rights limits your ability to engage in certain hedging transactions that could provide you with financial benefits.

By exercising the Subscription Rights, you are representing to us that you have not entered into any short sale or similar transaction with respect to our common stock since the record date for the Rights Offering.  This requirement prevents you from pursuing certain investment strategies that could provide you greater financial benefits than you might have realized if the Subscription Rights did not contain these requirements.

The Subscription Rights are not transferable, and there is no market for the Subscription Rights.

You may not sell, transfer, assign or give away your Subscription Rights.  Because the Subscription Rights are non-transferable, there is no market or other means for you to directly realize any value associated with the Subscription Rights.  You must exercise the Subscription Rights to realize any potential value from your Subscription Rights.

FORWARD-LOOKING STATEMENTS

Certain information presented in this prospectus supplement may contain “forward-looking statements” within the meaning of the federal securities laws including the Private Securities Litigation Reform Act of 1995.  Forward looking statements include statements concerning our plans, objectives, goals, strategies, future events, future revenues or performance, capital expenditures, financing needs, plans or intentions relating to acquisitions and other information that is not historical information.  In some cases, forward looking statements can be identified by terminology such as “believes,” “plans,” “intends,” “expects,” “estimates,” “may,” “will,” “should,” or “anticipates” or the negative of such terms or other comparable terminology, or by discussions of strategy.  All forward-looking statements by the company involve known and unknown risks, uncertainties and other factors, many of which are beyond the control of the company, which may cause the company’s actual results to be materially different from those expressed or implied by such statements.  We may also make additional forward-looking statements from time to time.  All such subsequent forward-looking statements, whether written or oral, by us or on our behalf, are also expressly qualified by these cautionary statements.  All forward-looking statements, including without limitation, management’s examination of historical operating trends and estimates of future earnings, are based upon our current expectations and various assumptions.  Our expectations, beliefs and projections are expressed in good faith and we believe there is a reasonable basis for them, but there can be no assurance that management’s expectations, beliefs and projections will result or be achieved.

All forward looking statements apply only as of the date made.  Except as required by law, we undertake no obligation to publicly update or revise forward looking statements which may be made to reflect events or circumstances after the date made or to reflect the occurrence of unanticipated events.  There are a number of risks and uncertainties that could cause our actual results to differ materially from the forward-looking statements contained in or contemplated by this prospectus supplement.

There are a number of risks and uncertainties that could cause our actual results to differ materially from the forward-looking statements contained in or contemplated by this prospectus supplement.  Any forward-looking statements should be considered in light of the risks referenced in “Risk Factors” beginning on page S-17 of this prospectus supplement and page 3 of the accompanying base prospectus and in “Item 1A. Risk Factors” included in our Annual Report on Form 10-K for the year ended December 31, 2018 and in the other documents that we file pursuant to Sections 13(a), 13(c), 14 or 15(d) of the Exchange Act after the date of this prospectus supplement, which will be considered to be incorporated by reference into this prospectus supplement and the accompanying base prospectus.  Such factors include, but are not limited to:

USE OF PROCEEDS

Assuming that all                 shares of our common stock are subscribed for in the Rights Offering, we estimate that the net proceeds from the Rights Offering will be approximately $11,224,500, after deducting expenses relating to the Rights Offering payable by us estimated at approximately $400,000.

We intend to use the net proceeds from the Rights Offering to fund a portion of the purchase price of the West Henrietta Property and related expenses described above under “Prospectus Supplement Summary—Recent Developments—West Henrietta Property Acquisition” and/or to repay borrowings under our revolving credit facility.  We intend to use any remaining proceeds to fund acquisitions of other self storage properties, to fund expansions of our existing self storage properties, and for working capital and general corporate purposes.  The acquisition of the West Henrietta Property is subject to due diligence and the satisfaction of customary closing conditions, and there can be no assurances that these conditions will be satisfied or that the acquisition will close on the terms described herein, or at all.

As of June 30, 2019, we have no outstanding balance under our revolving credit facility. Borrowings under our revolving credit facility bear interest at 3.00% over the One Month U.S. Dollar London Inter-Bank Offered Rate and are due to mature on December 20, 2021.

CAPITALIZATION

The following table sets forth our cash and cash equivalents and capitalization as of June 30, 2019: (1) on an actual basis and (2) on an adjusted basis after giving effect to the Rights Offering.  You should read this table in conjunction with “Use of Proceeds” in this prospectus supplement and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the year ended December 31, 2018 and our Quarterly Report on Form 10-Q for the quarter ended June 30, 2019, each of which is incorporated by reference herein.  No adjustments have been made to reflect normal course operations by us or other developments with our business after June 30, 2019, including the Rights Offering and the funding of the purchase price in connection with our expected acquisition of the West Henrietta Property. As a result, the adjusted information provided below is not indicative of our actual cash and cash equivalents position or consolidated capitalization as of any date.

(1)	Historical amounts are derived from our unaudited financial statements and related footnotes appearing in our Quarterly Report on Form 10-Q for the quarter ended June 30, 2019, which is incorporated by reference herein.

(2)	Our outstanding shares of common stock excludes all shares of common stock available for future grants under our equity incentive plan.

(3)	Does not reflect the payment of the purchase price in connection with our expected acquisition of the West Henrietta Property or the Use of Proceeds set forth in this Prospectus Supplement.

DILUTION

Purchasers of shares of our common stock in the Rights Offering will experience an immediate dilution of the net tangible book value per share of our common stock.  Our net tangible book value as of                 , 2019 was approximately $                 million, or $                 per share based upon                  shares of our common stock outstanding.  Net tangible book value per share is equal to our total tangible assets less our total liabilities, divided by the number of shares of our outstanding common stock.

Dilution per share of our common stock equals the difference between the amount per share of our common stock paid by purchasers of shares of our common stock in the Rights Offering and the net tangible book value per share of our common stock immediately after the Rights Offering.

Based on the sale by us in the Rights Offering of a maximum of                  shares of our common stock at the Subscription Price of $                 per share, and after deducting estimated offering expenses payable by us, our pro forma net tangible book value as of                 , 2019 would have been approximately $                 million, or $                 per share.  This represents an immediate increase in pro forma net tangible book value to existing stockholders of $                 per share and an immediate dilution to purchasers in the Rights Offering of $(                ) per share.  The following table illustrates this per-share dilution:

The number of shares of our common stock that will be outstanding immediately after the Rights Offering is based on                  shares of our common stock outstanding as of                 , 2019, and excludes all shares of our common stock available for future grants under our equity incentive plan as of                 , 2019.

THE RIGHTS OFFERING

The Subscription Rights

We are distributing to the record holders of shares of our common stock who are entitled to participate in the Rights Offering, at no charge, non-transferable Subscription Rights.  Each record holder of our common stock will receive one Subscription Right for every share of our common stock owned by such record holder as of 5:00 p.m., Eastern Time, on the Record Date.  Each Subscription Right consists of a Basic Subscription Right and an Over-Subscription Privilege.  The Subscription Rights will not be tradable.  The Subscription Rights will expire if they are not exercised by 5:00 p.m., Eastern Time, on the Expiration Date, unless we extend or earlier terminate the Rights Offering.

Basic Subscription Rights

You will receive one Basic Subscription Right for every share of our common stock that you owned as of 5:00 p.m., Eastern Time, on the Record Date.  The Basic Subscription Rights will entitle you to purchase one share of our common stock at a Subscription Price of $                 per share for each                  Basic Subscription Rights you hold.  Fractional shares of our common stock will not be issued upon the exercise of Basic Subscription Rights.  Accordingly, shares of our common stock may be purchased only pursuant to the exercise of Basic Subscription Rights in integral multiples of                 .  The total number of Basic Subscription Rights you receive will be rounded up to the nearest number of Subscription Rights evenly divisible by                 .

For example, if you owned                  shares of our common stock as of the Record Date, you will receive                  Basic Subscription Rights and will have the right to purchase                  shares of our common stock for $                 per share, or a total payment of $                .  Alternatively, for example, if you owned                  shares of our common stock as of the Record Date, you will receive                  Basic Subscription Rights and will have the right to purchase                  shares of our common stock for an aggregate purchase price of $                 per share (or a total payment of $                ).  You may exercise all or a portion of your Basic Subscription Rights, or you may choose not to exercise any of your Basic Subscription Rights.  If you do not exercise your Basic Subscription Rights in full, you will not be entitled to exercise your Over-Subscription Privilege.

Over-Subscription Privilege

If you exercise your Basic Subscription Rights in full, you may also choose to exercise your Over-Subscription Privilege.  Subject to proration and the limitations described in this prospectus supplement, we will seek to honor the Over-Subscription Requests in full.  If Over-Subscription Requests exceed the available number of shares, however, we will allocate the available shares of our common stock pro rata among the stockholders as of the record date exercising the Over-Subscription Privilege in proportion to the number of shares of our common stock those stockholders owned on the Record Date, relative to the number of shares owned on the Record Date by all stockholders as of the record date exercising the Over-Subscription Privilege.  If this pro rata allocation results in any stockholder receiving a greater number of shares of our common stock than the record holder subscribed for pursuant to the exercise of the Over-Subscription Privilege, then such record holder will be allocated only that number of shares of our common stock for which the record holder oversubscribed, and the remaining shares of our common stock will be allocated among all other holders exercising the Over-Subscription Privilege on the same pro rata basis described above.  The proration process will be repeated until all available shares of our common stock have been allocated.

Computershare Trust Company, N.A., the Subscription Agent for the Rights Offering, will determine the over-subscription allocation based on the formula described above.

To the extent the aggregate subscription payment of the actual number of unsubscribed shares of our common stock available to you pursuant to the Over-Subscription Privilege is less than the amount you actually paid in connection with the exercise of the Over-Subscription Privilege, you will be allocated only the number of unsubscribed shares of our common stock available to you, and any excess subscription payments will be returned to you, without interest or deduction, as soon as practicable after the Rights Offering has expired.

We can provide no assurances that you will actually be entitled to purchase the number of shares of our common stock issuable upon the exercise of your Over-Subscription Privilege in full at the expiration of the Rights Offering.  We may not be able to satisfy any requests for shares of our common stock pursuant to the Over-Subscription Privilege if all of our stockholders exercise their Basic Subscription Rights in full, and we will only honor an Over-Subscription Privilege to the extent sufficient shares of our common stock are available following the exercise of Basic Subscription Rights.

Limitation on the Purchase of Shares of our Common Stock

You may only purchase the number of shares of our common stock purchasable upon exercise of the number of Basic Subscription Rights distributed to you in the Rights Offering, plus the Over-Subscription Privilege, if any.  Accordingly, the number of shares of our common stock that you may purchase in the Rights Offering is limited by the number of shares of our common stock you held on the Record Date and by the extent to which other stockholders exercise their Basic Subscription Rights and Over-Subscription Privileges, which we cannot determine prior to completion of the Rights Offering.

To assist us in complying with the limitations on the concentration of ownership applicable to REITs, among other purposes, our charter provides that, subject to certain exceptions, no person or entity may own, or be deemed to own, by virtue of the applicable constructive ownership provisions of the Code, more than 9.8% in value or in number, whichever is more restrictive, of the outstanding shares of our common stock, or 9.8% in value or in number, whichever is more restrictive, of the outstanding shares of all classes and series of our capital stock.  Accordingly, the Basic Subscription Rights are subject to the limitation that no Basic Subscription Rights (including Over-Subscription Privileges) may be exercised if such exercise would result in the holder receiving shares of our common stock in violation of the ownership limits contained in our charter.  Any purported exercise of Basic Subscription Rights or Over-Subscription Privilege, and any delivery of shares of common stock upon a purported exercise, shall be void to the extent (but only to the extent) that such exercise and the receipt of common stock by the holder would result in such holder violating these ownership limitations.  See “Description of Securities—Restrictions on Ownership and Transfer” beginning on page 23 of the accompanying prospectus for more information about these restrictions.

Please also see the discussion under “The Rights Offering—The Subscription Rights—Over-Subscription Privilege” for a description of the potential proration as to the Over-Subscription Privilege.

Subscription Price

The Subscription Price is $                 per share.  The Subscription Price does not necessarily bear any relationship to our past or expected future results of operations, cash flows, current financial condition, or any other established criteria for value.  No change will be made to the Subscription Price by reason of changes in the trading price of our common stock or other factor prior to the expiration of the Rights Offering.

Determination of Subscription Price

In determining the Subscription Price, our board of directors considered, among other things, the following factors:

·	our need to raise capital in order to grow our business;

·	the current and historical trading prices of our common stock;

·	the price at which stockholders might be willing to participate in the Rights Offering;

·	our need for additional capital and liquidity;

·	the cost of capital from other sources; and

·	comparable precedent transactions, including the percentage of shares offered, the terms of the subscription rights being offered, the subscription price and the discount that the subscription price represented to the immediately prevailing closing prices for those offerings.

In conjunction with the review of these factors, our board of directors also reviewed our history and prospects, including our past and present earnings and cash requirements, our prospects for the future, the outlook for our industry and our current financial condition.  Our board of directors also believed that the Subscription Price should be designed to provide an incentive to our current stockholders to participate in the Rights Offering and exercise their Basic Subscription Right and their Over-Subscription Privilege.

The Subscription Price does not necessarily bear any relationship to any established criteria for value.  You should not consider the Subscription Price as an indication of actual value of our company or our common stock.  The market price of our common stock may decline during or after the Rights Offering.  You should obtain a current price quote for our common stock and perform an independent assessment of our common stock before exercising your Subscription Rights and make your own assessment of our business and financial condition, our prospects for the future, the terms of the Rights Offering, the information contained or incorporated by reference in this prospectus supplement and the accompanying base prospectus and the other considerations relevant to your circumstances.  Once made, except as otherwise set forth in this prospectus supplement, all exercises of Subscription Rights are irrevocable.

No Short-Sales

By exercising the Subscription rights, you are representing to us that you have not entered into any short sale or similar transaction with respect to our common stock since the record date for the Rights Offering.  This requirement prevents you from pursuing certain investment strategies that could provide you greater financial benefits than you might have realized if the Subscription Rights did not contain these requirements.

Non-Transferability of Subscription Rights

The Subscription Rights are non-transferable (other than by operation of law) and, therefore, you may not sell, transfer, assign or give away your Subscription Rights to anyone.  The Subscription Rights will not be listed for trading on any stock exchange or market.

Expiration Date; Extension

The subscription period, during which you may exercise your Subscription Rights, expires at 5:00 p.m., Eastern Time, on the Expiration Date.  If you do not exercise your Subscription Rights before that time, your Subscription Rights will expire and will no longer be exercisable.  We will not be required to issue shares to you if the Subscription Agent receives your Rights Certificate or your subscription payment after that time.  We have the option to extend the Rights Offering in our sole discretion.  We may extend the Rights Offering by giving oral or written notice to the Subscription Agent before the Rights Offering expires.  If we elect to extend the Rights Offering, we will issue a press release announcing the extension no later than 9:00 a.m., Eastern Time, on the next business day after the most recently announced expiration date of the Rights Offering.

If you hold your shares of our common stock in the name of a broker, dealer, bank or other nominee, the nominee will exercise the Subscription Rights on your behalf in accordance with your instructions.  Please note that the nominee may establish a deadline that may be before 5:00 p.m., Eastern Time, on the Expiration Date.

Termination

We may terminate the Rights Offering at any time and for any reason prior to the completion of the Rights Offering.  If we terminate the Rights Offering, we will issue a press release notifying stockholders and the public of the termination.

Return of Funds upon Completion or Termination

The Subscription Agent will hold funds received in payment for shares in a segregated account pending completion of the Rights Offering.  The Subscription Agent will hold this money until the Rights Offering is completed or is terminated.  To the extent you properly exercise your Over-Subscription Privilege for an amount of shares of our common stock that exceeds the number of unsubscribed shares of our common stock available to you, any excess subscription payments will be returned to you as soon as practicable after the Rights Offering has expired, without interest or deduction.  If the Rights Offering is terminated for any reason, all subscription payments received by the Subscription Agent will be returned as soon as practicable, without interest or deduction.

Amendment to the Terms of the Rights Offering

We reserve the right to amend or modify the terms of the Rights Offering in our sole discretion.  However, if we make a Material Change, we will circulate an updated prospectus supplement reflecting the modified terms in advance of 5:00 p.m., Eastern Time, on the Expiration Date, unless extended, and you may cancel your subscription and receive a refund of any money you have advanced.

Shares of Our Capital Stock Outstanding After the Rights Offering

Assuming no other transactions by us involving our capital stock prior to the expiration of the Rights Offering, and if the Rights Offering is fully subscribed, upon consummation of the Rights Offering we will have                  shares of our common stock issued and outstanding, based on                  shares of our common stock outstanding as of                 , 2019.  The exact number of shares of our common stock that we will issue in the Rights Offering will depend on the number of shares of our common stock that are subscribed for in the Rights Offering.

Methods for Exercising Subscription Rights

Except as otherwise set forth in this prospectus supplement, the exercise of Subscription Rights is irrevocable and may not be cancelled or modified.  You may exercise your Subscription Rights as follows:

Subscription by Record Holders

If you are a stockholder of record, the number of shares of our common stock you may purchase pursuant to your Subscription Rights is indicated on the enclosed Rights Certificate.  You may exercise your Subscription Rights by properly completing and executing the Rights Certificate and forwarding it, together with your full payment, to the Subscription Agent at the address given below under “Subscription Agent,” to be received before 5:00 p.m., Eastern Time, on the Expiration Date.

Subscription by Beneficial Owners

If you are a beneficial owner of shares of our common stock that are registered in the name of a broker, dealer, bank or other nominee, you will not receive a Rights Certificate.  Instead, we will issue one Subscription Right to such nominee record holder for all shares of our common stock held by such nominee at the Record Date.  If you are not contacted by your nominee, you should promptly contact your nominee in order to subscribe for shares in the Rights Offering and follow the instructions provided by your nominee.

To properly exercise your Over-Subscription Privilege, you must deliver the subscription payment related to your Over-Subscription Privilege before the Rights Offering expires.  Because we will not know the total number of unsubscribed shares of our common stock before the Rights Offering expires, if you wish to maximize the number of shares you purchase pursuant to your Over-Subscription Privilege, you will need to deliver payment in an amount equal to the aggregate subscription payment for the maximum number of shares of our common stock that you wish to purchase.

Payment Method

Payments must be made in full in U.S. currency by personal check payable to “Computershare Trust Company, N.A., as Subscription Agent for Global Self Storage, Inc.” You must timely pay the full subscription

payment, including payment for the Over-Subscription Privilege, for the full number of shares of our common stock you wish to acquire pursuant to the exercise of Subscription Rights by delivering a personal check drawn against a U.S. bank payable to “Computershare Trust Company, N.A., as Subscription Agent for Global Self Storage, Inc.”

If you send a personal check, payment will not be deemed to have been received by the Subscription Agent until the check has cleared.  The clearinghouse may require five or more business days to clear a personal check.  Accordingly, holders who wish to pay the Subscription Price by means of a personal check should make payment sufficiently in advance of the expiration of the Rights Offering to ensure that the payment is received and clears by that date.

You should read the instruction letter accompanying the Rights Certificate carefully and strictly follow it.  DO NOT SEND RIGHTS CERTIFICATES OR PAYMENTS DIRECTLY TO US.  We will not consider your subscription received until the Subscription Agent has received delivery of a properly completed and duly executed Rights Certificate and payment of the full subscription payment.

The method of delivery of Rights Certificates and payment of the subscription payment to the Subscription Agent will be at the risk of the holders of Subscription Rights.  If sent by mail, we recommend that you send those certificates and payments by registered mail, properly insured, with return receipt requested, or by overnight courier, and that you allow a sufficient number of days to ensure delivery to the Subscription Agent and clearance of payment before the Rights Offering expires.

Missing or Incomplete Subscription Forms or Payment

If you fail to complete and sign the Rights Certificate or otherwise fail to follow the subscription procedures that apply to the exercise of your Subscription Rights before the Rights Offering expires, the Subscription Agent will reject your subscription or accept it to the extent of the payment received.  Neither we nor our Subscription Agent undertakes any responsibility or action to contact you concerning an incomplete or incorrect subscription form, nor are we under any obligation to correct such forms.  We have the sole discretion to determine whether a subscription exercise properly complies with the subscription procedures.

If you send a payment that is insufficient to purchase the number of shares you requested, or if the number of shares you requested is not specified in the forms, the payment received will be applied to exercise your Subscription Rights to the fullest extent possible based on the amount of the payment received.  Any excess subscription payments received by the Subscription Agent will be returned, without interest or deduction, as soon as practicable after the Rights Offering has expired.

Issuance of Common Stock

The shares of our common stock that are purchased in the Rights Offering will be issued in book-entry, or uncertificated, form meaning that you will receive a DRS account statement from our transfer agent reflecting ownership of these securities if you are a holder of record of shares.  If you hold your shares of our common stock in the name of a bank, broker, dealer, or other nominee, DTC will credit your account with your nominee with the securities you purchased in the Rights Offering.

The Subscription Agent for the Rights Offering is Computershare Trust Company, N.A.  The address to which Rights Certificates and payments should be mailed or delivered by overnight courier is provided below.  If sent by mail, we recommend that you send documents and payments by registered mail, properly insured, with return receipt requested, and that you allow a sufficient number of days to ensure delivery to the Subscription Agent and clearance or payment before the Rights Offering expires.  Do not send or deliver these materials to us.

If you deliver the Rights Certificates in a manner different than that described in this prospectus supplement, we may not honor the exercise of your Subscription Rights.

No Fractional Shares

The Basic Subscription Rights will entitle you to purchase one share of our common stock at the Subscription Price for each                  Basic Subscription Rights you hold.  Fractional shares of our common stock will not be issued upon the exercise of Basic Subscription Rights.  Accordingly, shares of our common stock may be purchased only pursuant to the exercise of Basic Subscription Rights in integral multiples of                 .  The total number of Basic Subscription Rights you receive will be rounded up to the nearest number of Subscription Rights evenly divisible by                 .  Any excess subscription payments received by the Subscription Agent will be returned as soon as practicable after the Rights Offering has expired, without interest or deduction.

Notice to Brokers and Nominees

If you are a broker, dealer, bank or other nominee holder that holds shares of our common stock for the account of others on the Record Date, you should notify the beneficial owners of the shares for whom you are the nominee of the Rights Offering as soon as possible to learn their intentions with respect to exercising their Subscription Rights.  If a beneficial owner of our common stock so instructs, you should complete the Rights Certificate and submit it to the Subscription Agent with the proper subscription payment by the Expiration Date.  You may exercise the number of Subscription Rights to which all of your beneficial owners in the aggregate otherwise would have been entitled had they been direct holders of shares of our common stock on the Record Date, provided that you, as a nominee record holder, make a proper showing to the Subscription Agent by submitting the form entitled “Nominee Holder Certification,” which is provided with your Rights Offering materials.  If you did not receive this form, you may contact our Information Agent to request a copy.

Validity of Subscriptions

We will resolve all questions regarding the validity and form of the exercise of your Subscription Rights, including time of receipt and eligibility to participate in the Rights Offering.  Our determination will be final and binding.  Once made, except as otherwise set forth in this prospectus supplement, subscriptions are irrevocable; we will not accept any alternative, conditional, or contingent subscriptions.  We reserve the absolute right to reject any subscriptions not properly submitted or the acceptance of which would be unlawful.  You must resolve any irregularities in connection with your subscriptions before the Expiration Date of the Rights Offering, unless we waive them in our sole discretion.  Neither we nor the Subscription Agent is under any duty to notify you or your representative of defects in your subscriptions.  A subscription will be considered accepted, subject to our right to withdraw or terminate the Rights Offering, only when the Subscription Agent receives a properly completed and duly executed Rights Certificate and any other required documents and the full subscription payment including final clearance of any personal check.  Our interpretations of the terms and conditions of the Rights Offering will be final and binding.

Stockholder Rights

You will have no rights as a holder of the shares of our common stock you purchase in the Rights Offering until shares are issued in book-entry form or your account at your broker, dealer, bank, or other nominee is credited with the shares of our common stock purchased in the Rights Offering.

Foreign Holders

We will not mail this prospectus or Rights Certificates to stockholders with addresses that are outside the United States or that have an army post office or foreign post office address.  The Subscription Agent will hold these Rights Certificates for their account.  To exercise Subscription Rights, our foreign holders must notify the Subscription Agent prior to 5:00 p.m., Eastern Time, on December 13, 2019, the third business day prior to the Expiration Date, of your exercise of Subscription Rights and provide evidence satisfactory to us, such as a legal opinion from local counsel, that the exercise of such Subscription Rights does not violate the laws of the jurisdiction in which such holders reside and payment by a U.S. bank in U.S. dollars before the expiration of the offer.  If no notice is received by such time or the evidence presented is not satisfactory to us, the Subscription Rights represented thereby will expire.

No Revocation or Change

Once you submit the Rights Certificate or have instructed your nominee of your subscription request, you are not allowed to revoke or change the exercise or request a refund of monies paid.  All exercises of Subscription Rights are irrevocable, even if you learn information about us that you consider to be unfavorable.  However, if we make a Material Change, you may cancel your subscription and receive a refund of any money you have advanced.  You should not exercise your Subscription Rights unless you are certain that you wish to purchase shares at the Subscription Price.

U.S. Federal Income Tax Treatment of Rights Distribution

For U.S. federal income tax purposes, we do not believe holders of shares of our common stock should recognize income or loss upon receipt or exercise of a Subscription Right.  See “Additional U.S. Federal Income Tax Consequences.”

No Recommendation to Subscription Rights Holders

Our board of directors is not making a recommendation regarding your exercise of the Subscription Rights.  Stockholders who exercise Subscription Rights risk investment loss on money invested.  We cannot predict the price at which our shares of our common stock will trade after the Rights Offering.  You should make your investment decision based on your assessment of our business and financial condition, our prospects for the future and the terms of the Rights Offering.  Please see “Risk Factors” for a discussion of some of the risks involved in investing in our common stock.

Fees and Expenses

We will pay all fees charged by the Subscription and Information Agent.  You are responsible for paying any other commissions, fees, taxes or other expenses incurred in connection with the exercise of your Subscription Rights.

Listing

The Subscription Rights may not be sold, transferred, assigned or given away to anyone, and will not be listed for trading on any stock exchange or market.  The shares of our common stock to be issued in the Rights Offering are traded on NASDAQ under the symbol “SELF.”

Important

Do not send Rights Certificates directly to us.  You are responsible for choosing the payment and delivery method for your Rights Certificate and you bear the risks associated with such delivery.  If you choose to deliver your Rights Certificate and payment by mail, we recommend that you use registered mail, properly insured, with return receipt requested.  We also recommend that you allow a sufficient number of days to ensure delivery to the Subscription Agent and clearance of payment prior to the expiration of the Rights Offering.

Other Matters

We are not making the Rights Offering in any state or other jurisdiction in which it is unlawful to do so, nor are we distributing or accepting any offers to purchase any shares of our common stock from Subscription Rights holders who are residents of those states or other jurisdictions or who are otherwise prohibited by federal or state laws or regulations from accepting or exercising the Subscription Rights.  We may delay the commencement of the Rights Offering in those states or other jurisdictions, or change the terms of the Rights Offering, in whole or in part, in order to comply with the securities laws or other legal requirements of those states or other jurisdictions.  Subject to state securities laws and regulations, we also have the discretion to delay allocation and distribution of any shares you may elect to purchase by exercise of your Subscription Privilege in order to comply with the securities laws of any applicable state or other jurisdiction.  We may decline to make modifications to the terms of the Rights Offering requested by those states or other jurisdictions, in which case, if you are a resident in those states or jurisdictions or if you are otherwise prohibited by federal, state or other laws or regulations from accepting or exercising the subscription rights, you will not be eligible to participate in the Rights Offering.

ADDITIONAL U.S. FEDERAL INCOME TAX CONSEQUENCES

The following discussion is a summary of additional U.S. federal income tax considerations applicable to the receipt and exercise (or expiration) of the Subscription Rights acquired through the Rights Offering and provides certain additional U.S. federal income tax considerations with respect to ownership of shares of our common stock acquired as a result of exercise of the Subscription Rights.  Prospective investors should review the discussion in the accompanying base prospectus under the heading “U.S. Federal Income Tax Considerations,” for a more detailed summary of the U.S. federal income tax consequences of the purchase, ownership and disposition of our common stock and our election to be subject to U.S. federal income tax as a REIT.  Terms not otherwise defined herein have the meaning assigned to them in the accompanying base prospectus.

This discussion is based on the Code, the regulations promulgated by the U.S. Treasury Department, or the Treasury Regulations, current administrative interpretations and practices of the IRS (including administrative interpretations and practices expressed in private letter rulings which are binding on the IRS only with respect to the particular taxpayers who requested and received those rulings) and judicial decisions, all as currently in effect, and all of which are subject to differing interpretations or to change, possibly with retroactive effect.  No assurance can be given that the IRS would not assert, or that a court would not sustain, a position contrary to any of the tax consequences described below, which could adversely affect a holder of the Subscription Rights or shares of our common stock.  No advance ruling has been or will be sought from the IRS regarding any matter discussed in this summary.  There can be no assurance the IRS or a court will not take a contrary position to that discussed below regarding the tax consequences of the receipt of Subscription Rights acquired through the Rights Offering, the exercise (or expiration) of the Subscription Rights and the acquisition, ownership and disposition of shares of our common stock.  This summary is also based upon the assumption that the operation of the company, and of its subsidiaries and other lower-tier and affiliated entities, will in each case be in accordance with its applicable organizational documents or partnership agreements.  This summary does not address any U.S. federal estate or gift tax consequences, the alternative minimum tax, or any state, local, or non-U.S. tax consequences.  This summary is for general information only, and does not purport to discuss all aspects of U.S. federal income taxation that may be important to a particular holder of Subscription Rights in light of its investment or tax circumstances, or to holders subject to special tax rules,

This discussion is limited to holders that hold the Subscription Rights and shares of our common stock, in each case, as a “capital asset” within the meaning of Section 1221 of the Code (generally, property held for investment).  This discussion does not address all U.S. federal income tax consequences relevant to a holder’s particular circumstances, including the impact of the unearned income Medicare contribution tax.  In addition, it does not address consequences relevant to holders subject to particular rules, including, without limitation:

·	U.S. expatriates and former citizens or long-term residents of the United States;

·	persons who mark-to-market our common stock;

·	brokers, dealers or traders in securities;

·	subchapter S corporations;

·	U.S. stockholders (as defined below) whose functional currency is not the U.S. dollar;

·	financial institutions;

·	insurance companies;

·	broker-dealers;

·	regulated investment companies;

·

REITs;

·	holders who receive our common stock through the exercise of employee share options or otherwise as compensation;

·	persons holding our common stock as part of a “straddle,” “hedge,” “conversion transaction,” “synthetic security” or other integrated investment;

·	persons subject to the alternative minimum tax provisions of the Code;

·	persons holding their interest through a partnership or similar pass-through entity;

·	persons holding a 10% or more (by vote or value) beneficial interest in us;

·	“controlled foreign corporations,” “passive foreign investment companies,” and corporations that accumulate earnings to avoid U.S. federal income tax;

·	persons deemed to sell the Subscription Rights, shares of our common stock or shares of our common stock under the constructive sale provisions of the Code;

·	persons for whom our stock constitutes “qualified small business stock” within the meaning of Section 1202 of the Code;

·	tax-exempt organizations;

and, except to the extent discussed below:

·	non-U.S. holders (as defined below).

If an entity treated as a partnership for U.S. federal income tax purposes holds our common stock, Subscription Rights or common stock acquired upon exercise of Subscription Rights, as the case may be, the tax treatment of a partner in the partnership will depend on the status of the partner, the activities of the partnership and certain determinations made at the partner level.  Accordingly, partnerships and the partners in such partnerships should consult their tax advisors regarding the U.S. federal income tax consequences to them.

THIS DISCUSSION IS FOR INFORMATION PURPOSES ONLY AND IS NOT TAX ADVICE.  INVESTORS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES OF THE RECEIPT, OWNERSHIP AND EXERCISE OF SUBSCRIPTION RIGHTS AND THE ACQUISITION, OWNERSHIP, AND DISPOSITION OF SHARES OF OUR COMMON STOCK ACQUIRED UPON EXERCISE OF SUBSCRIPTION RIGHTS ARISING UNDER THE U.S. FEDERAL ESTATE OR GIFT TAX LAWS OR UNDER THE LAWS OF ANY STATE, LOCAL OR NON-U.S. TAXING JURISDICTION OR UNDER ANY APPLICABLE INCOME TAX TREATY.

Definition of a U.S. Holder

For purposes of this discussion, a “U.S. holder” is any beneficial owner of shares of our common stock, Subscription Rights or common stock acquired upon exercise of Subscription Rights, as the case may be, that, for U.S. federal income tax purposes, is:

·	an individual who is a citizen or resident of the United States;

·	a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) created or organized under the laws of the United States, any state thereof, or the District of Columbia;

·	an estate, the income of which is subject to U.S. federal income tax regardless of its source; or

·

a trust that (1) is subject to the primary supervision of a U.S. court and the control of one or more United States persons (within the meaning of Section 7701(a)(30) of the Code), or (2) has made a valid election under applicable Treasury Regulations to continue to be treated as a United States person.

Receipt of Subscription Rights

Although the authorities governing transactions such as the Rights Offering are complex and do not speak directly to the consequences of certain aspects of the Rights Offering, including the effects of the Over-Subscription Privilege, we do not believe a U.S. holder’s receipt of Subscription Rights pursuant to the Rights Offering should be treated as a taxable distribution with respect to their existing shares of our common stock for U.S. federal income tax purposes.  Section 305(a) of the Code states that a stockholder’s taxable income does not include in-kind stock dividends, including distributions of stock rights; however, the general non-recognition rule in Section 305(a) of the Code is subject to exceptions described in Section 305(b) of the Code, which include “disproportionate distributions.” A disproportionate distribution is a distribution or a series of distributions, including deemed distributions, that has the effect of the receipt of cash or other property by some stockholders or holders of debt instruments convertible into stock and an increase in the proportionate interest of other stockholders in a corporation’s assets or earnings and profits.  We do not believe that the receipt of Subscription Rights pursuant to the Rights Offering is a disproportionate distribution for these purposes.

Our position regarding the tax-free treatment of the Subscription Right distribution is not binding on the IRS, or the courts.  If this position is finally determined by the IRS or a court to be incorrect, whether on the basis that the issuance of the Subscription Rights is a “disproportionate distribution” or otherwise, the fair market value of the Subscription Rights would be taxable to U.S. holders of shares of our common stock as a dividend to the extent of the U.S. holder’s pro rata share of our current and accumulated earnings and profits, if any, with any excess being treated as a return of capital to the extent thereof and then as capital gain.  If our position is incorrect, the tax consequences applicable to the holders may also be materially different than as described below.

The following discussion is based upon the treatment of the Subscription Right issuance as a non-taxable distribution with respect to a U.S. holders’ existing shares of our common stock for U.S. federal income tax purposes.

Tax Basis in the Subscription Rights

If the fair market value of the Subscription Rights a U.S. holder receives is less than 15% of the fair market value of the U.S. holder’s existing shares of our common stock (with respect to which the Subscription Rights are distributed) on the date the U.S. holder receives the Subscription Rights, the Subscription Rights will be allocated a zero tax basis for U.S. federal income tax purposes, unless the U.S. holder elects to allocate its tax basis in its existing shares of our common stock between its existing shares of our common stock and the Subscription Rights in proportion to the relative fair market values of the existing shares of our common stock and the Subscription Rights determined on the date of receipt of the Subscription Rights.  If a U.S. holder chooses to allocate tax basis between its existing common shares and the Subscription Rights, the U.S. holder must make this election on a statement included with its timely filed tax return (including extensions) for the taxable year in which the U.S. holder receives the Subscription Rights.  Such an election is irrevocable.  However, if the fair market value of the Subscription Rights a U.S. holder receives is 15% or more of the fair market value of their existing shares of our common stock on the date the U.S. holder receives the Subscription Rights, then the U.S. holder must allocate its tax basis in its existing shares of our common stock between those shares and the Subscription Rights the U.S. holder receives in proportion to their fair market values determined on the date the U.S. holder receives the Subscription Rights.  Please refer to the discussion below regarding the U.S. tax treatment of a U.S. holder that, at the time of the receipt of the Subscription Right, no longer holds the common stock with respect to which the Subscription Right was distributed.

The fair market value of the Subscription Rights on the date that the Subscription Rights are distributed is uncertain, and we have not obtained, and do not intend to obtain, an appraisal of the fair market value of the Subscription Rights on that date.  In determining the fair market value of the Subscription Rights, U.S. holders should consider all relevant facts and circumstances, including any difference between the Subscription Price of the Subscription Rights and the trading price of our shares of our common stock on the date that the Subscription Rights

are distributed, the fair market value of the common stock, the length of the period during which the Subscription Rights may be exercised and the fact that the Subscription Rights are non-transferable.

Exercise of Subscription Rights

Generally, a U.S. holder will not recognize gain or loss upon the exercise of a Subscription Right in the Rights Offering.  A U.S. holder’s adjusted tax basis, if any, in the Subscription Right plus the Subscription Price should be allocated between the new shares of our common stock acquired upon exercise of the Subscription Right in proportion to their relative fair market values on the exercise date.  This allocation will establish the U.S. holder’s initial tax basis for U.S. federal income tax purposes in the new shares of our common stock received upon exercise.  The holding period of the common stock acquired upon exercise of a Subscription Right in the Rights Offering will begin on the date of exercise.

If, at the time of the receipt or exercise of the Subscription Right, the U.S. holder no longer holds the common stock with respect to which the Subscription Right was distributed, then certain aspects of the tax treatment of the receipt and exercise of the Subscription Right are unclear, including (1) the allocation of the tax basis between the shares of our common stock previously sold and the Subscription Right, (2) the impact of such allocation on the amount and timing of gain or loss recognized with respect to the shares of our common stock previously sold, and (3) the impact of such allocation on the tax basis of the shares of our common stock acquired upon exercise of the Subscription Right.  If a U.S. holder exercises a Subscription Right received in the Rights Offering after disposing of shares of our common stock with respect to which the Subscription Right is received, the U.S. holder should consult its tax advisor.

Expiration of Subscription Rights

If a U.S. holder allows Subscription Rights received in the Rights Offering to expire, the U.S. holder should not recognize any gain or loss for U.S. federal income tax purposes, and the U.S. holder should re-allocate any portion of the tax basis in its existing common shares previously allocated to the Subscription Rights that have expired to the existing common shares.

Tax Considerations Applicable to Non-U.S. Holders

For purposes of this discussion, a “non-U.S. holder” is a beneficial owner of shares of our common stock, Subscription Rights or shares of our common stock acquired upon exercise of a Subscription Right that is neither a U.S. holder nor an entity treated as a partnership for U.S. federal income tax purposes.

Ownership and Disposition of Our Common Stock

The tax consequences of owning and disposing of common stock received upon exercise of the Subscription Rights are described in the accompanying base prospectus under “U.S. Federal Income Tax Considerations—Taxation of Taxable U.S. Stockholders.”

Receipt, Exercise and Expiration of the Subscription Rights

The U.S. federal income tax consequences of the receipt, exercise, and expiration of the Subscription Rights to a non-U.S. holder are generally the same as for a U.S. holder.  See “—Tax Consequences Applicable to U.S. Holders—Receipt of Subscription Rights” above.

Ownership and Disposition of Our Common Stock

The tax consequences of owning and disposing of common stock received upon exercise of the Subscription Rights are described in the accompanying base prospectus under “U.S. Federal Income Tax Considerations—Taxation of Non-U.S. Stockholders.”
