Equinix Europe 2 Financing 424B5Prospectus supplement for primary offering

Equinix Europe 2 Financing Corporation LLC is an indirect, wholly-owned finance subsidiary of Equinix, Inc. The Issuer conducts no independent operations and has no operating assets other than as related to the issuance, administration, repayment and hedging of any debt securities that the Issuer may issue in the future and that will be fully and unconditionally guaranteed by Equinix, Inc. As such, the Issuer’s sole activity is to borrow funds and lend those funds to Equinix, Inc. and its other subsidiaries, which loans will be reflected as intercompany receivables. The Issuer’s ability to pay interest and repay principal in respect of its indebtedness, including the notes, depends upon the receipt of payments from Equinix, Inc. and its other subsidiaries. Therefore, investors should primarily consider the financial condition and liquidity of Equinix, Inc. and its other subsidiaries rather than that of the Issuer.

Equinix, Inc.’s subsidiaries are separate and distinct legal entities with no obligation to pay any amounts due pursuant to the notes or to provide the Issuer with funds for the Issuer’s payment obligations. Substantially all of our operations are conducted through our subsidiaries and we derive substantially all our revenues from our subsidiaries, and substantially all of our operating assets are owned by our subsidiaries. As a result, Equinix, Inc.’s cash flow and ability to service its indebtedness, including the intercompany payables to Equinix Europe 2 Financing Corporation LLC or any obligations under the guarantee of the notes, depends in large part on the earnings of our subsidiaries and on the distribution of earnings, loans or other payments to Equinix, Inc. by its subsidiaries. Payments to Equinix, Inc. by its subsidiaries also will be contingent upon their earnings and their business considerations. In addition, the ability of Equinix, Inc.’s subsidiaries to make any dividend, distribution, loan or other payment to Equinix, Inc. could be subject to statutory or contractual restrictions. Because Equinix, Inc. depends in large part on the cash flow of its subsidiaries to meet its obligations, these types of restrictions may impair Equinix, Inc.’s ability to make payments to the Issuer who may be unable to make scheduled interest and principal payments on the notes and may also impair Equinix, Inc.’s ability to meet its obligations under the guarantee of the notes. Equinix, Inc.’s subsidiaries held approximately 92% of our consolidated assets as of March 31, 2024.

The notes will be the Issuer’s general unsecured senior obligations, ranking equal in right of payment with the Issuer’s existing and any future unsubordinated indebtedness. In addition, Equinix, Inc.’s obligations under the guarantee will rank equally with all of its other unsecured and unsubordinated indebtedness. Because neither the notes nor the guarantee is secured, they will be effectively junior to any of the Issuer’s or Equinix, Inc.’s existing or future secured indebtedness to the extent of the value of the assets securing such debt, respectively. As of March 31, 2024, Equinix, Inc. had approximately $15.9 billion of consolidated indebtedness, which included finance lease liabilities, mortgage and loans payable and senior notes, of which approximately $25.8 million was secured debt. As of March 31, 2024, after giving effect to this offering, we would have had total consolidated indebtedness of approximately $      , approximately $25.8 million of which would have represented secured indebtedness, which excludes approximately $2.2 billion of finance lease liabilities.

The guarantee and the ability of Equinix, Inc. to make payments on the intercompany payables to the Issuer will be structurally subordinated to all of the liabilities of other subsidiaries of Equinix, Inc., which may include indebtedness, trade payables, guarantees, lease obligations and letter of credit obligations. In the event of a bankruptcy, liquidation or reorganization of any of Equinix, Inc.’s subsidiaries, holders of their indebtedness and their trade creditors will generally be entitled to payment of their claims from the assets of those subsidiaries before any assets of the subsidiaries are made available for distribution to Equinix, Inc. As of March 31, 2024, after giving effect to this offering, Equinix, Inc.’s subsidiaries would have had $      of indebtedness (excluding trade payables and intercompany items and liabilities of a type not required to be reflected on a balance sheet of such subsidiaries in accordance with GAAP), which includes $1.9 billion of finance lease liabilities, all of which would be structurally senior to the guarantee.

Equinix, Inc.’s obligations under its guarantee of the notes may be subject to review under state or federal fraudulent transfer laws in the event of Equinix, Inc.’s bankruptcy or other financial difficulty. Under those laws, in a lawsuit by an unpaid creditor or representative of creditors of Equinix, Inc., such as a trustee in bankruptcy, if a court were to find that, when Equinix, Inc. entered into the guarantee, it received less than fair consideration or reasonably equivalent value for the guarantee and either:

then the court could void the guarantee and Equinix, Inc.’s obligations under the guarantee and direct the return of any amounts paid under the guarantee to Equinix, Inc. or to a fund for the benefit of its creditors. Furthermore, to the extent that Equinix, Inc.’s obligations under the guarantee of the notes exceed the actual benefit that it receives from the issuance of the notes, Equinix, Inc. may be deemed not to have received fair consideration or reasonably equivalent value from the guarantee. As a result, the guarantee and Equinix, Inc.’s obligations under the guarantee may be void. The measure of insolvency for purposes of the factors above will vary depending on the law of the jurisdiction being applied. Generally, however, an entity would be considered insolvent if the sum of its debts (including contingent or unliquidated debts) is greater than all of its property at a fair valuation or if the present fair saleable value of its assets is less than the amount that will be required to pay its probable liability on its existing debts as they become absolute and matured.

The terms of our debt instruments, including the indenture and supplemental indenture governing the notes offered hereby and the agreement governing Equinix, Inc.’s revolving credit facility, permit the Issuer,

As of March 31, 2024, Equinix, Inc. had approximately $3.9 billion of additional liquidity available to it from its $4.0 billion revolving credit facility, subject to its compliance with the financial covenants and other conditions precedent set forth in the credit agreement relating to such facility.

While the indenture, supplemental indenture and the notes offered hereby contain terms intended to provide protections to holders upon the occurrence of certain events involving significant corporate transactions or our creditworthiness, these terms are limited and may not be sufficient to protect your investment in the notes. The provisions in the indenture and the supplemental indenture governing the notes offered hereby relating to change of control transactions will not necessarily afford you protection in the event of a highly leveraged transaction that may adversely affect you, including a reorganization, restructuring, merger or other similar transaction involving us. These transactions may not involve a change in voting power or beneficial ownership or, even if they do, may not involve a change of the magnitude required under the definition of change of control triggering event in the supplemental indenture governing the notes offered hereby to trigger these provisions, including the requirement that the transactions be accompanied or followed within 60 days by a downgrade in the rating of the notes below certain levels by at least two ratings agencies. Except as described under “Description of Notes—Change of Control Triggering Event”, the indenture will not contain provisions that permit the holders of the notes to require the Issuer to repurchase the notes in the event of a takeover, recapitalization or similar transaction. Further, the definition of change of control, which is a condition precedent to a change of control triggering event, includes a phrase relating to the sale, transfer, conveyance or other disposition of “all or substantially all” of the Guarantor’s assets. There is no precisely established definition of the phrase “substantially all” under applicable law. Accordingly, your ability to require the Issuer to repurchase your notes as a result of a sale, transfer, conveyance or other disposition of less than all of the Guarantor’s assets to another individual, group or entity may be uncertain.

The notes is a new issue of securities with no trading history or established trading market. We will not apply to have the notes listed on any exchange or automated dealer quotation system and we cannot assure

This section describes the notes. The Issuer will issue the notes under a supplemental indenture (the “Supplemental Indenture”) to that certain base indenture, dated as of March 18, 2024 (together with the Supplemental Indenture, the “Indenture”), between itself, as Issuer, Equinix, Inc., as guarantor (the “Guarantor”, the Issuer and the Guarantor are collectively referred to as the “Obligors”) and U.S. Bank Trust Company, National Association, as Trustee (the “Trustee”). The following is a summary of the material provisions of the Indenture. The Indenture will comply with the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). The terms of the notes include those stated in the Indenture and those made part of the Indenture by reference to certain provisions of the Trust Indenture Act. You can find definitions of certain capitalized terms used in this description under “—Certain Definitions.”

You are encouraged to read the Indenture because it, and not this description, defines your rights as a holder of the notes. Copies of the Indenture are available upon request to the Issuer at the address indicated under “Where You Can Find More Information” in this prospectus supplement.

The Issuer will issue the notes in fully registered form in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. The Trustee will initially act as paying agent and registrar for the notes. The notes may be presented for registration or transfer and exchange at the offices of the registrar. The Issuer may change any paying agent and registrar without notice to registered holders of the notes (the “Holders”). The Issuer will pay principal (and premium, if any) on the notes at the Corporate Trust Office of the Trustee. At the Issuer’s option, interest may be paid at the Corporate Trust Office of the Trustee or by check mailed to the registered address of Holders.

Interest on the notes will accrue at a rate of    % per annum. Interest on the notes will be payable semi-annually in arrears on         and         of each year commencing on           . The Issuer will pay interest to those persons who were Holders of record on the               or            immediately preceding each interest payment date. Interest on the notes will accrue from the date of original issuance or, if interest has already been paid, from the date it was most recently paid. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months.

The notes will be general senior obligations of the Issuer. The Holders’ right to payment under these notes will be:

As of May 22, 2024, the Issuer had no subsidiaries. As of March 31, 2024, after giving effect to this offering:

Prior to               , 20   (      months prior to their maturity date) (the “Par Call Date”), the Issuer may redeem the notes at its option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

On or after the Par Call Date, the Issuer may redeem the notes, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the notes being redeemed plus accrued and unpaid interest thereon to, but excluding, the redemption date.

Neither the Trustee nor any paying agent shall have any obligation to calculate or verify the calculation of the make-whole premium. The Issuer’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error.

The Treasury Rate shall be determined by the Issuer after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” ​(or any successor designation or publication) under the caption “U.S. government securities—Treasury constant maturities—Nominal” ​(or any successor caption or heading) (‘‘H.15 TCM’’). In determining the Treasury Rate, the Issuer shall select, as applicable:

For purposes of the foregoing, the transfer (by lease, assignment, sale or otherwise, in a single transaction or series of transactions) of all or substantially all of the properties or assets of one or more Restricted Subsidiaries of the Guarantor, in a single or a series of related transactions, which properties and assets, if held by the Guarantor instead of such Restricted Subsidiaries, would constitute all or substantially all of the properties and assets of the Guarantor on a consolidated basis, shall be deemed to be the transfer of all or substantially all of the properties and assets of the Guarantor.

Notwithstanding the foregoing clauses 1, 2 and 3, but subject to the proviso in clause 1(A) and clause 2(A), the Issuer and the Guarantor may merge with (a) any of the Guarantor’s Wholly Owned Restricted Subsidiaries, (b) in the case of the Issuer, the Guarantor, or (c) an Affiliate that is a Person that has no material assets or liabilities and which was organized solely for the purpose of reorganizing the Issuer or the Guarantor in another jurisdiction.

The Indenture will provide that upon any consolidation, combination or merger or any transfer of all or substantially all of the assets of the Issuer or the Guarantor in accordance with the foregoing in which the Issuer or the Guarantor is not the continuing Person, the successor Person formed by such consolidation or into which the Issuer or the Guarantor is merged or to which such conveyance, lease or transfer is made shall succeed to, and be substituted for, and may exercise every right and power of, the Issuer and the Guarantor under the Indenture and the notes with the same effect as if such surviving entity had been named as such and all financial information and reports required by the Indenture shall be provided by and for such surviving entity.

For the avoidance of doubt, following an Equinix Substitution, this covenant shall cease to apply to the Issuer. Nothing in this covenant shall prevent the Guarantor from consummating an Equinix Substitution or prevent the Guarantor or any Restricted Subsidiary from consummating the Guarantor Conversion.

The Issuer may, at its option and at any time, elect to have its obligations discharged with respect to the outstanding notes (“Legal Defeasance”). Such Legal Defeasance means that the Issuer shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding notes, except for:

In addition, the Issuer may, at its option and at any time, elect to have the obligations of the Obligors released with respect to certain covenants that are described in the Indenture (“Covenant Defeasance”) and thereafter any omission to comply with such obligations shall not constitute a Default or Event of Default with respect to the notes. In the event Covenant Defeasance occurs, certain events (not including non-payment, bankruptcy, receivership, reorganization and insolvency events) described under “—Events of Default” will no longer constitute an Event of Default with respect to the notes.

Except as provided in the next two succeeding paragraphs, the Obligors and the Trustee with the consent of the Holders of at least a majority in aggregate principal amount of the notes then outstanding (including consents obtained in connection with a tender offer or exchange offer for such notes) may amend the Indenture or the notes and the Holders of at least a majority in aggregate principal amount of the notes outstanding may waive any past Default or compliance with any provisions of the Indenture or the notes.

The Indenture and the notes may be amended by the Obligors and the Trustee without the consent of any Holder of the notes to:

The consent of the Holders of the notes is not necessary to approve the particular form of any proposed amendment. It is sufficient if such consent approves the substance of the proposed amendment.

The Indenture will provide that the Indenture, the notes and the guarantee will be governed by, and construed in accordance with, the laws of the State of New York but without giving effect to applicable principles of conflicts of law to the extent that the application of the law of another jurisdiction would be required thereby.

The Indenture will provide that, except during the continuance of an Event of Default, the Trustee will perform only such duties as are specifically set forth in the Indenture. During the existence of an Event of Default, the Trustee will exercise such rights and powers vested in it by the Indenture, and use the same degree of care and skill in its exercise as a prudent person would exercise or use under the circumstances in the conduct of his own affairs.

The Indenture and the provisions of the Trust Indenture Act contain certain limitations on the rights of the Trustee, should it become a creditor of the Issuer or the Guarantor, to obtain payments of claims in certain cases or to realize on certain property received in respect of any such claim as security or otherwise. Subject to the Trust Indenture Act, the Trustee will be permitted to engage in other transactions; provided that if the Trustee acquires any conflicting interest as described in the Trust Indenture Act, it must eliminate such conflict or resign.

Any action required or permitted to be taken by the Board of Directors of the Obligors pursuant to the terms of the Indenture may be taken by a duly constituted committee of the Board of Directors or any officer, director, or authorized representative of such Obligor, in each case duly authorized by such board or Managers, as applicable, to act hereunder.

The notes will be issued in the form of one or more fully registered global notes without coupons that will be deposited with The Depository Trust Company, New York, New York (“DTC”), and registered in the name of its nominee, Cede & Co. This means that the Issuer will not issue certificates to each owner of notes. The global notes will be issued to DTC, which will keep a computerized record of its participants (for example, your broker) whose clients have purchased the notes. The participant will then keep a record of its clients who purchased the notes. Unless it is exchanged in whole or in part for a certificated note, a global note may not be transferred, except that DTC, its nominees, and their successors may transfer a global note as a whole to one another. The rules applicable to DTC and its direct and indirect participants are on file with the SEC.

The following are the material U.S. federal income tax consequences of ownership and disposition of the notes. This discussion applies only to notes that are:

This discussion does not describe any state, local or non-U.S. tax consequences or any U.S. federal tax consequences other than income tax consequences (such as estate or gift tax consequences). This discussion does not describe all of the U.S. federal income tax consequences that may be relevant to a holder in light of the holder’s particular circumstances, including alternative minimum tax or Medicare contribution tax consequences, or tax consequences applicable to holders subject to special rules, such as:

If an entity or arrangement that is classified as a partnership for U.S. federal income tax purposes holds notes, the U.S. federal income tax treatment of a partner will generally depend on the status of the partner and the activities of the partnership. Partnerships considering an investment in the notes and partners in such partnerships should consult their tax advisors as to their particular U.S. federal income tax consequences of holding and disposing of the notes.

This summary is based on the Code, administrative pronouncements, judicial decisions and final, temporary and proposed Treasury Regulations, changes to or different interpretations of any of which subsequent to the date of this prospectus supplement may affect the tax consequences described herein, possibly on a retroactive basis. Persons considering the purchase of notes are urged to consult their tax advisors with regard to the application of the U.S. federal income tax laws to their particular situations as well as any tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

As used herein, the term “U.S. Holder” means a beneficial owner of a note that is, for U.S. federal income tax purposes:

As used herein, the term “Non-U.S. Holder” means a beneficial owner of a note that is, for U.S. federal income tax purposes:

“Non-U.S. Holder” does not include a nonresident alien individual present in the United States for 183 days or more in the taxable year of disposition of the notes. Such a holder is urged to consult his or her own tax advisor regarding the U.S. federal income tax consequences of the ownership and disposition of the notes.

If a Non-U.S. Holder cannot meet the above requirements, such Non-U.S. Holder will be subject to U.S. federal withholding tax at a rate of 30% (or lower applicable treaty rate) on any payments of interest on the notes that are not effectively connected with the conduct of a United States trade or business. To claim a reduction in or exemption from such withholding under an applicable treaty, the Non-U.S. Holder must provide the applicable withholding agent with a properly executed IRS Form W-8BEN or W-8BEN-E claiming such entitlement.

If a Non-U.S. Holder is engaged in a trade or business in the United States, and if interest on the note is effectively connected with the conduct of this trade or business, unless an applicable income tax treaty provides otherwise, payments of interest to the Non-U.S. Holder will be exempt from the withholding tax discussed in the preceding paragraph and will generally be taxed in the same manner as payments of interest to a U.S. Holder (see “Tax Consequences to U.S. Holders” above), except that the Non-U.S. Holder will be required to provide a properly executed IRS Form W-8ECI (or other applicable form) in order to claim an exemption from the withholding tax discussed in the preceding paragraph. Non-U.S. Holders are urged to consult their own tax advisors regarding whether an applicable income tax treaty provides for a different result and regarding other U.S. tax consequences of the ownership and disposition of notes, including for a corporate Non-U.S. Holder the possible imposition of a branch profits tax at a rate of 30% (or a lower treaty rate) on its effectively connected earnings and profits, subject to adjustments.

We and the underwriters for the offering named below have entered into an underwriting agreement with respect to the notes. Barclays Capital Inc., BNP Paribas Securities Corp., BofA Securities, Inc., Goldman Sachs & Co. LLC, HSBC Securities (USA) Inc., and J.P. Morgan Securities LLC are acting as representatives of the underwriters. Subject to certain conditions, each underwriter has severally agreed to purchase the principal amount of the notes indicated in the following table opposite the name of such underwriter.

Notes sold by the underwriters to the public will initially be offered at the initial public offering prices set forth on the cover of this prospectus supplement. The underwriters may offer the notes to selected dealers at the public offering price minus a concession of up to    % of the principal amount of the notes. The underwriters may allow, and such other dealers may reallow, a concession not in excess of    % of the principal amount of the notes, respectively, to certain other dealers. If all the notes are not sold at the initial offering price, the underwriters may change the offering price and the other selling terms.

The notes is a new issue of securities with no established trading market. We will not apply for listing of the notes on any securities exchange or any automated dealer quotation system. We have been advised by certain of the underwriters that the underwriters currently intend to make a market in the notes but are not obligated to do so and may discontinue market making at any time without notice. No assurance can be given as to the liquidity of the trading market for the notes.

In connection with the offering, the underwriters may purchase and sell notes in the open market. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater number of notes than they are required to purchase in the offering. Stabilizing transactions consist of certain bids or purchases made for the purpose of preventing or retarding a decline in the market price of the notes while the offering is in progress.

The underwriters also may impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the representatives have repurchased notes sold by or for the account of such underwriter in stabilizing or short covering transactions.

These activities by the underwriters, as well as other purchases by the underwriters for their own accounts, may stabilize, maintain or otherwise affect the market price of the notes. As a result, the price of the notes may be higher than the price that otherwise might exist in the open market. If these activities are commenced, they may be discontinued by the underwriters at any time without notice. These transactions may be effected in the over-the-counter market or otherwise.

It is expected that delivery of the notes will be made against payment therefor on or about          , 2024, which is the fifth business day following the date of pricing of the notes (such settlement cycle being referred to as “T+5”). Under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in two business days unless the parties to any such trade

We estimate that our total expenses for this offering, other than the underwriting discount, will be approximately $      . The underwriters have agreed to pay or to reimburse us for a portion of our out-of-pocket expenses incurred in connection with this offering.

Certain of the underwriters or their affiliates act as sales agents under our “at-the-market” program. Certain affiliates of the underwriters act as lenders and/or agents under our existing credit facilities or have other lending relationships with us, certain of the underwriters have acted as underwriters for offerings of our common stock and/or our existing senior notes, and certain underwriters and their affiliates may from time to time hold our senior notes for their own account. Certain of the underwriters or their affiliates routinely hedge, certain of the underwriters or their affiliates are likely to hedge or otherwise reduce, and certain other of the underwriters or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, these underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the notes offered hereby.

In addition, from time to time, certain of the underwriters and their affiliates may effect transactions for their own account or the account of customers, and hold on behalf of themselves or their customers, long or short positions in our debt or equity securities or loans, and may do so in the future. In the ordinary course of their various business activities, the underwriters and their respective affiliates, officers, directors and employees may purchase, sell or hold a broad array of investments and actively trade securities, derivatives, loans, commodities, currencies, credit default swaps and other financial instruments for their own account and for the accounts of their customers, and such investment and trading activities may involve or relate to our assets, securities and/or instruments (directly, as collateral securing other obligations or otherwise) and/or persons and entities with relationships with us. The underwriters and their respective affiliates may also communicate independent investment recommendations, market color or trading ideas and/or publish or express independent research views in respect of such assets, securities or instruments and may at any time hold, or recommend to clients that they should acquire, long and/or short positions in such assets, securities and instruments.

You should be aware that the laws and practices of certain countries require investors to pay stamp taxes and other charges in connection with purchases of securities.

The following summary of the terms of Equinix, Inc.’s capital stock is not meant to be complete and is qualified by reference to the relevant provisions of the Delaware General Corporation Law (the “DGCL”) and Equinix, Inc.’s amended and restated certificate of incorporation (our “certificate of incorporation”) and amended and restated bylaws (our “bylaws”). Our certificate of incorporation and bylaws are incorporated by reference as exhibits to the registration statement of which this prospectus forms a part. See “Where You Can Find More Information” above. As used in this section under the heading “Description of Capital Stock”, the terms “we”, “our” and “us” refer to Equinix, Inc. only, unless otherwise indicated or the context otherwise requires.

Under our certificate of incorporation, our authorized capital stock consists of 300,000,000 shares of common stock, par value $0.001 per share, and 100,000,000 shares of preferred stock, $0.001 par value per share.

The holders of our common stock are entitled to one vote per share on all matters to be voted on by the stockholders. Subject to preferences that may be applicable to any outstanding preferred stock, the holders of common stock are entitled to receive ratably such dividends, if any, as may be declared from time to time by the board of directors out of funds legally available for the payment of dividends. All dividends are non-cumulative. In the event of the liquidation, dissolution or winding up of Equinix, Inc., the holders of common stock are entitled to share ratably in all assets remaining after payment of liabilities, subject to prior distribution rights of preferred stock, if any, then outstanding. Our common stock has no preemptive or conversion rights or other subscription rights. There are no redemption or sinking fund provisions applicable to the common stock. All outstanding shares of our common stock are fully paid and nonassessable.

Preferred stock may be issued from time to time in one or more series, each of which is to have the voting powers, designation, preferences and relative, participating, optional or other special rights and qualifications, limitations or restrictions thereof as are stated and expressed in our certificate of incorporation, or in a resolution or resolutions providing for the issue of that series adopted by our board of directors.

Our board of directors has the authority, without stockholder approval, to create one or more series of preferred stock and, with respect to each series, to fix or alter as permitted by law, among other things, the number of shares of the series and the designation thereof, dividend rights, dividend rate, conversion rights, voting rights, rights and terms of any redemption, redemption price or prices and liquidation preferences.

The foregoing provisions on transferability and ownership will not apply if our board of directors determines that it is no longer in our best interests to attempt to qualify, or to continue to qualify, as a REIT.

Any person who acquires or attempts or intends to acquire beneficial or constructive ownership of shares of capital stock that will or may violate the ownership limits or any of the other foregoing restrictions on transferability and ownership will be required to give notice to us immediately (or, in the case of a proposed or attempted transaction, at least 15 days prior to such transaction) and provide us with such other information as we may request in order to determine the effect, if any, of such transfer on our qualification as a REIT.

Pursuant to our certificate of incorporation, if there is any purported transfer of our capital stock or other event or change of circumstances that, if effective or otherwise, would violate any of the restrictions described above, then the number of shares causing the violation (rounded up to the nearest whole share) will be automatically transferred to a trust for the exclusive benefit of a designated charitable beneficiary, except that any transfer that results in the violation of the restriction relating to our capital stock being beneficially owned by fewer than 100 persons will be automatically void and of no force or effect. The automatic transfer will be effective as of the close of business on the business day prior to the date of the purported transfer or other event or change of circumstances that requires the transfer to the trust. We refer below to the person that would have owned the shares if they had not been transferred to the trust as the purported transferee. Any ordinary dividend paid to the purported transferee, prior to our discovery that the shares had been automatically transferred to a trust as described above, must be repaid to a trustee designated in accordance with the certificate of incorporation upon demand. Our certificate of incorporation also provides for adjustments to the entitlement to receive extraordinary dividends and other distributions as between the purported transferee and the trust. If the transfer to the trust as described above is not automatically effective, for any reason, to prevent violation of the applicable restriction contained in our certificate of incorporation, then the transfer of the excess shares will be automatically void and of no force or effect.

Shares of our capital stock transferred to the trustee are deemed to be offered for sale to us or our designee at a price per share equal to the lesser of (i) the price per share in the transaction that resulted in such transfer to the trust or, if the purported transferee did not give value for the shares in connection with the event causing the shares to be held in trust (e.g., in the case of a gift, devise or other such transaction), the market price at the time of such event and (ii) the market price on the date we accept, or our designee accepts, such offer. We have the right to accept such offer until the trustee has sold the shares of our capital stock held in the trust pursuant to the clauses described below. Upon a sale to us, the interest of the charitable beneficiary in the shares sold terminates and the trustee must distribute the net proceeds of the sale to the purported transferee, except that the trustee may reduce the amount payable to the purported transferee by the amount of any ordinary dividends that we paid to the purported transferee prior to our discovery that the shares had been transferred to the trust and that is owed by the purported transferee to the trustee as described above. Any net sales proceeds and extraordinary dividends in excess of the amount payable to the purported transferee shall be immediately paid to the charitable beneficiary, and any ordinary dividends held by the trustee with respect to such capital stock will be promptly paid to the charitable beneficiary.

After receiving notice that the shares have been transferred to the trust, the trustee must, as soon as reasonably practicable (and, if the shares are listed on a national securities exchange, within 20 days) after receiving notice from us of the transfer of shares to the trust, sell the shares to a person or entity who could own the shares without violating the restrictions described above. Upon such a sale, the trustee must distribute to the purported transferee an amount equal to the lesser of (i) the price paid by the purported transferee for the shares or, if the purported transferee did not give value for the shares in connection with the event causing the shares to be held in trust (e.g., in the case of a gift, devise or other such transaction), the market price of the shares on the day of the event causing the shares to be held in the trust, and (ii) the sales proceeds (net of commissions and other expenses of sale) received by the trustee for the shares. The trustee may reduce the
