NOW, THEREFORE, to comply with the provisions of the Indenture, and in consideration of the above premises, the Company, the Subsidiary Guarantors and the Trustee covenant and agree as follows:

ARTICLE 1

Section 1.01 Nature of Supplemental Indenture. This Twenty-Third Supplemental Indenture supplements the Indenture and does and shall be deemed to form a part of, and shall be construed in connection with and as part of, the Indenture for any and all purposes.

Section 1.02 Establishment of New Series. Pursuant to Section 2.2 of the Indenture, there is hereby established the Exchangeable Debentures having the terms, in addition to those set forth in the Indenture and this Twenty-Third Supplemental Indenture, set forth in the form of Exchangeable Debenture, attached to this Twenty-Third Supplemental Indenture as Exhibit A, which is incorporated herein as a part of this Twenty-Third Supplemental Indenture.

Section 1.03 Redemption. (a) The Company shall have the right to redeem the Exchangeable Debentures for cash, in whole or in part, (i) at any time, if the Company determines it is necessary to redeem the Exchangeable Debentures in order to preserve Host REIT’s status as a real estate investment trust and (ii) at any time or from time to time, on or after April 20, 2012, in each case, upon the notice set forth in Section 1.04 of this Twenty-Third Supplemental Indenture at a Redemption Price equal to 100% of the principal amount of the Exchangeable Debentures to be redeemed plus unpaid interest (including Liquidated Damages, if any) accrued thereon to, but excluding, the Redemption Date; provided, however that if the Redemption Date falls after a Record Date and on or prior to the corresponding interest payment date, the Company will pay the full amount of accrued and unpaid interest, if any, on such interest payment date to the Holder of record at the close of business on the corresponding Record Date (instead of the Holder surrendering its Exchangeable Debentures for redemption). In connection with any redemption by the Company pursuant to clause (i) in this Section 1.03(a), the Company shall provide the Trustee with an Officers’ Certificate evidencing that the Host REIT Board of Directors has, in good faith, made the determination that it is necessary to redeem the Exchangeable Debentures in order to preserve the Guarantor’s status as a real estate investment trust. If the Paying Agent holds money sufficient to pay the Redemption Price due on an Exchangeable Debenture on the Redemption Date, then, on and after the Redemption Date, that Exchangeable Debenture will cease to be outstanding and interest on that Exchangeable Debenture will cease to accrue, whether or not the Holder effects a book-entry transfer of that Exchangeable Debenture or delivers that Exchangeable Debenture to the Paying Agent. Thereafter, all other rights of the Holder of that Exchangeable Debenture terminate, other than the right to receive the Redemption Price due on the Redemption Date.

(b) The Company shall not redeem the Exchangeable Debentures pursuant to Section 1.03(a) on any date if the principal amount of the Exchangeable Debentures has been accelerated, and such an acceleration has not been rescinded or cured on or prior to such date (except in the case of an acceleration resulting from a default by the Company in the payment of the Redemption Price with respect to the Exchangeable Debentures to be redeemed).

(c) If less than all of the Exchangeable Debentures are to be redeemed, the Trustee shall select the Exchangeable Debentures to be redeemed (in principal amounts of $1,000 or multiples thereof) on a pro rata basis or by another method the Trustee deems fair and appropriate or is required by the Depositary; provided, that if any Exchangeable Debenture selected for partial redemption is exchanged in part before termination of the right to exchange such Exchangeable Debenture pursuant to Article 6 with respect to the portion of the Exchangeable Debenture so selected, the exchanged portion of such Exchangeable Debenture shall be deemed (so far as may be) to be the portion selected for redemption. Exchangeable Debentures which have been exchanged during a selection of Exchangeable Debentures to be redeemed may be treated by the Trustee as outstanding for the purpose of such selection.

(d) In the event of any redemption, the Company will not be required to:

(i) Issue or register the transfer or exchange of any Exchangeable Debenture during a period beginning at 9:00 a.m., New York City time 15 days before any selection of Exchangeable Debentures to be redeemed and ending at 5:00 p.m., New York City time on the day of mailing of the relevant notice of redemption, or

(ii) Register the transfer or exchange of any Exchangeable Debenture, or portion thereof, called for redemption, except the unredeemed portion of any Exchangeable Debenture being redeemed in part.

(e) If the Company calls the Exchangeable Debentures for redemption, a Holder may exchange its Exchangeable Debentures only until 5:00 p.m., New York City time on the second Business Day immediately preceding the Redemption Date, unless the Company fails to pay the Redemption Price.

Section 1.04 Notice of Optional Redemption. In case the Company shall desire to exercise the right to redeem all or, as the case may be, any part of the Exchangeable Debentures pursuant to Section 1.03, the Company shall be subject to the notice requirements of Article 3 of the Indenture, except the Company, or the Trustee in the name of and at the expense of the Company, shall mail or cause to be mailed a notice of such redemption not fewer than fifteen (15) calendar days nor more than sixty (60) calendar days prior to the Redemption Date to each Holder of Exchangeable Debentures so to be redeemed in whole or in part at its last address as the same appears on the Exchangeable Debenture Register.

Section 1.05 Tax Withholding. The Company or Host REIT is permitted to deduct, withhold and pay to the applicable governmental authority from payment of interest otherwise due to Holder, from cash payable to a Holder on redemption or from shares of Host REIT Common Stock otherwise deliverable to a Holder upon exchange of an Exchangeable Debenture, and from any other payment made with respect to an Exchangeable Debenture, any amount that either the Company or Host REIT is required by applicable laws to withhold, and any amount so deducted, withheld and paid over shall be deemed paid to such Holder for all purposes of this Indenture.

Section 1.06 Sinking Fund. There shall be no sinking fund provided for the Exchangeable Debentures.

Section 1.07 For purposes of the Exchangeable Debentures, Section 8.5 of the Indenture shall be amended to read:

“The Trustee and each Paying Agent shall pay to the Company upon request any money held by them for the payment of principal or interest that remains unclaimed for two years after a right to such money has matured; provided, however, that the Trustee or such Paying Agent, before being required to make any such payment, may, at the expense of the Company, either publish in a newspaper of general circulation in The City of New York, or cause to be mailed to each Holder entitled to such money, notice that such money remains unclaimed and that after a date specified therein, which shall be at least thirty (30) calendar days from the date of such mailing or publication, any unclaimed balance of such money then remaining will be repaid to the Company. After payment to the Company, Holders entitled to money must look to the Company for payment as general creditors unless an applicable abandoned property law designates another person, and the Trustee and each Paying Agent shall be relieved of all liability with respect to such money.”

If the Trustee cannot reasonably obtain at least one bid for a $5,000,000 principal amount of Exchangeable Debentures from a nationally recognized securities dealer or, in the Company’s reasonable judgment, the bid quotations are not indicative of the secondary market value of the Exchangeable Debentures, then the Trading Price per $1,000 principal amount of Exchangeable Debentures will be deemed to be less than 95% of the product of the Closing Sale Price of Host REIT Common Stock and the Exchange Rate on such determination date.

“Volume Weighted Average Price” per share of Host REIT Common Stock on any Trading Day will be the volume weighted average price on The New York Stock Exchange or, if Host REIT Common Stock is not listed on The New York Stock Exchange, on the principal exchange or over-the-counter market on which Host REIT common stock is then listed or traded, from 9:30 a.m. to 4:00 p.m., New York City time, on that Trading Day as displayed on Bloomberg Page “HST.N <Equity> AQR” (or any successor thereto), or if such volume weighted average price is not available, then the “volume weighted average price” will be the market value per share of Host REIT Common Stock on such Trading Day as determined by a nationally recognized independent investment banking firm retained by the Company for such purpose.

ARTICLE 5

Section 5.01 Repurchase at Option of Holders upon a Designated Event. (a) For purposes of the Exchangeable Debentures, Section 10.1(a) of the Indenture is hereby replaced and superceded by the following and the following shall apply to the Exchangeable Debentures:

“10.1(a) If there shall occur a Designated Event prior to April 15, 2012, then each Holder shall have the right, at such Holder’s option, to require the Company to repurchase all of such Holder’s Exchangeable Debentures, or any portion thereof that is a multiple of $1,000 principal amount, in cash, on a date (the “Designated Event Repurchase Date”) specified by the Company, which may be no earlier than fifteen (15) days and no later than thirty (30) days after the date of the Issuer Repurchase Notice related to such Designated Event, at a repurchase price equal to 100% of the principal amount of the Exchangeable Debentures being repurchased, plus accrued and unpaid interest (including Liquidated Damages, if any) to, but excluding, the Designated Event Repurchase Date. A “Designated Event” will be deemed to have occurred upon a Change in Control or a Termination of Trading.”

(b) For purposes of the Exchangeable Debentures, Section 10.1(b) of the Indenture is hereby replaced and superceded by the following and the following shall apply to the Exchangeable Debentures:

“(b) On or before the thirtieth calendar day after the occurrence of a Designated Event, the Company shall mail or cause to be mailed to all Holders of record on the date of the Designated Event an Issuer Repurchase Notice as set forth in Section 5.03 of the Twenty-Third Supplemental Indenture with respect to such Designated Event. The Company shall also deliver a copy of the Issuer Repurchase Notice to the Trustee and the Paying Agent at such time as it is mailed to Holders. In addition to the mailing of such Issuer Repurchase Notice, the Company shall disseminate a press release through Dow Xxxxx & Company, Inc. or Bloomberg Business News or a substantially equivalent financial news organization announcing the occurrence of the Designated Event and publish such information in a newspaper of general circulation in The City of New York, or on Host REIT’s website, or through such other public medium as the Company shall deem appropriate at such time. No failure of the Company to give the foregoing notices and no defect therein shall limit the Holders’ repurchase rights or affect the validity of the proceedings for the repurchase of the Exchangeable Debentures pursuant to this Section 10.1(b).”

(c) For purposes of the Exchangeable Debentures, Section 10.1 of the Indenture is hereby supplemented by adding the following:

“(c) For an Exchangeable Debenture to be repurchased at the option of the

Holder pursuant to this Section 10.1, the Holder must deliver to the Paying Agent, prior to 5:00 p.m., New York City time, on the third Business Day immediately prior to the Designated Event Repurchase Date, (i) a written notice of repurchase (the “Designated Event Repurchase Notice”) in the form set forth on the reverse of the Exchangeable Debenture duly completed (if the Exchangeable Debenture is certificated) or stating the following (if the Exchangeable Debenture is represented by a Global Debenture): (A) the certificate number of the Exchangeable Debenture that the Holder will deliver to be repurchased (if the Exchangeable Debenture is certificated), (B) the portion of the principal amount of the Exchangeable Debenture which the Holder will deliver to be repurchased, which portion must be in principal amounts of $1,000 or an integral multiple of $1,000 (provided that the remaining principal amount of Exchangeable Debentures not subject to repurchase must be in an authorized denomination) and (C) that such Exchangeable Debenture shall be repurchased as of the Designated Event Repurchase Date pursuant to the terms and conditions specified in the Exchangeable Debenture and in the Twenty-Third Supplemental Indenture; together with (ii) such Exchangeable Debentures duly endorsed for transfer (if the Exchangeable Debenture if certificated) or book-entry transfer of such Exchangeable Debenture (if such Exchangeable Debenture is represented by a Global Debenture) in compliance with appropriate DTC procedures. The delivery of such Exchangeable Debenture to the Paying Agent with, or at any time after delivery of, the Repurchase Notice (together with all necessary endorsements) at the office of the Paying Agent shall be a condition to the receipt by the Holder of the repurchase price therefore; provided, however, that such repurchase price shall be so paid pursuant to this Section 10.1 only if the Exchangeable Debentures so delivered to the Paying Agent shall conform in all respects to the description thereof in the Repurchase Notice. All questions as to the validity, eligibility (including time of receipt) and acceptance of any Exchangeable Debenture for repurchase shall be determined by the Company, whose determination shall be final and binding absent manifest error.

(d) The Company, if so requested, shall repurchase from the Holder thereof, pursuant to this Section 10.01, a portion of an Exchangeable Debenture, if the principal amount of such portion is $1,000 or a whole multiple of $1,000. Provisions of the Twenty-Third Supplemental Indenture that apply to the repurchase of all of an Exchangeable Debenture also apply to the repurchase of such portion of such Exchangeable Debenture.

(e) The Paying Agent shall promptly notify the Company of the receipt by it of any Repurchase Notice or written notice of withdrawal thereof.

(f) Any repurchase by the Company contemplated pursuant to the provisions of this Section 10.1 shall be consummated by the delivery of the consideration to be received by the Holder (i) on the Designated Event Repurchase Date if the book-entry transfer or delivery of the Exchangeable Debentures to the Paying Agent is effected prior to the close of business on the third Business Day prior to the Designated Event Repurchase Date, and (ii) if delivered later, within two (2) Business Days following the later of the Designated Event

Repurchase Date and the time of the book-entry transfer or delivery of the Exchangeable Debenture. Payment of the repurchase price for an Exchangeable Debenture for which a Repurchase Notice has been delivered and not withdrawn is conditioned upon book-entry transfer or delivery of the Exchangeable Debentures, together with necessary endorsements, to the Paying Agent.”

(g) The Company may arrange for a third party to purchase any Exchangeable Debentures for which the Company receives a valid Designated Event Repurchase Notice that is not withdrawn, in the manner and otherwise in compliance with this Twenty-Third Supplemental Indenture and the Indenture applicable to the offer to repurchase the Exchangeable Debentures. If a third party purchases any Exchangeable Debentures under these circumstances, then interest will continue to accrue on such Exchangeable Debentures repurchased, and those Debentures will continue to be outstanding after the repurchase date and will be fungible with all other Exchangeable Debentures then outstanding. Such third party subsequently may resell those purchased Exchangeable Debentures to other investors.

Section 5.02 Repurchase at Option of Holders. (a) Each Holder shall have the right, at such Holder’s option, to require the Company to repurchase all of such Holder’s Exchangeable Debentures, or any portion thereof that is a multiple of $1,000 principal amount, in cash, on April 15, 2012, April 15, 2017 and April 15, 2022 (each, a “Repurchase Date”), at a repurchase price of 100% of the principal amount of the Exchangeable Debentures being repurchased, plus accrued and unpaid interest to, but excluding, the Repurchase Date; provided, however, that if the Repurchase Date falls after a Record Date and on or prior to the corresponding interest payment date, the Company will pay the full amount of accrued and unpaid interest, if any, on such interest payment date to the Holder of record at the close of business on the corresponding Record Date and the repurchase price will be 100% of the principal amount of the Exchangeable Debentures to be repurchased.

(b) On or before the twentieth Business Day immediately preceding each Repurchase Date, the Company shall mail or cause to be mailed to all Holders of record on such date (and to beneficial owners as required by applicable law) an Issuer Repurchase Notice as set forth in Section 5.03. The Company shall also deliver a copy of the Issuer Repurchase Notice to the Trustee and the Paying Agent at such time as it is mailed to Holders. In addition to the mailing of such Issuer Repurchase Notice, the Company shall disseminate a press release through Dow Xxxxx & Company, Inc. or Bloomberg Business News containing the information specified in such notice or publish such information in The Wall Street Journal or another newspaper of general circulation in The City of New York or on Host REIT’s website, or through such other public medium as the Company shall deem appropriate at such time. No failure of the Company to give the foregoing notices and no defect therein shall limit the Holders’ repurchase rights or affect the validity of the proceedings for the repurchase of the Exchangeable Debentures pursuant to this Section 5.02.

(c) For an Exchangeable Debenture to be so repurchased at the option of the Holder pursuant to this Section 5.02, the Holder must deliver to the Paying Agent, during the period beginning at 9:00 a.m., New York City time, on the date that is twenty (20) Business Days prior to the applicable Repurchase Date and ending at 5:00 p.m., New York City time, on the second Business Day immediately prior to the applicable Repurchase Date, (i) a written notice of repurchase (the “Repurchase Notice”) in the form set forth on the reverse of the Exchangeable Debenture duly completed (if the Exchangeable Debenture is certificated) or stating the following (if the Exchangeable Debenture is represented by a Global Debenture): (A) the certificate number of the Exchangeable Debenture which the Holder will deliver to be repurchased (if the Exchangeable Debenture is certificated) or that the relevant Repurchase Notice complies with the appropriate Depositary procedures (if the Exchangeable Debenture is represented by Global Debenture), (B) the portion of the principal amount of the Exchangeable Debenture which the Holder will deliver to be repurchased, which portion must be in principal amounts of $1,000 or an integral multiple of $1,000 (provided that the remaining principal amount of Exchangeable Debentures not subject to repurchase must be in an integral multiple of $1,000) and (C) that such Exchangeable Debenture shall be repurchased as of the Repurchase Date pursuant to the terms and conditions specified in the Exchangeable Debenture and in this Twenty-Third Supplemental Indenture and the Indenture; together with (ii) such Exchangeable Debentures duly endorsed for transfer (if the Exchangeable Debenture if certificated) or book entry transfer of such Exchangeable Debenture (if such Exchangeable Debenture is represented by a Global Debenture). The delivery of such Exchangeable Debenture to the Paying Agent with, or at any time after delivery of, the Repurchase Notice (together with all necessary endorsements) at the office of the Paying Agent shall be a condition to the receipt by the Holder of the repurchase price; provided, however, that such repurchase price shall be so paid pursuant to this Section 5.02 only if the Exchangeable Debentures so delivered to the Paying Agent shall conform in all respects to the description thereof in the Repurchase Notice. All questions as to the validity, eligibility (including time of receipt) and acceptance of any Exchangeable Debenture for repurchase shall be determined by the Company, whose determination shall be final and binding absent manifest error.

(d) The Company, if so requested, shall repurchase from the Holder thereof, pursuant to this Section 5.02, a portion of an Exchangeable Debenture, if the principal amount of such portion is $1,000 or a whole multiple of $1,000. Provisions of this Twenty-Third Supplemental Indenture that apply to the repurchase of all of an Exchangeable Debenture also apply to the repurchase of such portion of such Exchangeable Debenture.

(e) The Paying Agent shall promptly notify the Company of the receipt by it of any Repurchase Notice or written notice of withdrawal thereof.

(f) Any repurchase by the Company contemplated pursuant to the provisions of this Section 5.02 shall be consummated by the delivery of the consideration to be received by the Holder (i) on the Repurchase Date if the book-entry transfer or delivery of the

Exchangeable Debentures to the Paying Agent is effected prior to the close of business on the Business Day prior to the Repurchase Date, and (ii) if delivered later, within two (2) Business Days following the time of the book-entry transfer or delivery of the Exchangeable Debenture. Payment of the repurchase price for an Exchangeable Debenture for which a Repurchase Notice has been delivered and not withdrawn is conditioned upon book-entry transfer or delivery of the Exchangeable Debentures, together with necessary endorsements, to the Paying Agent.

Section 5.03 Issuer Repurchase Notice. (a) The Issuer Repurchase Notice, as provided in Section 5.03(b), shall be given to Holders within the time limits set forth in Section 5.01(b) or 5.02(b), as the case may be (in either case, the “Issuer Repurchase Notice Date”).

(b) In connection with any repurchase of Exchangeable Debentures, the Company shall, on the applicable Issuer Repurchase Notice Date, give written notice to Holders (with a copy to the Trustee) setting forth information specified in this Section 5.03 (in either case, the “Issuer Repurchase Notice”).

Each Issuer Repurchase Notice shall:

(i) state the repurchase price, and the Designated Event Repurchase Date or the Repurchase Date to which the relevant Issuer Repurchase Notice relates,

(ii) state, if applicable, the circumstances constituting the Designated Event,

(iii) state that Holders must exercise their right to elect to repurchase prior to 5:00 p.m., New York City time, on the second Business Day immediately prior to the Repurchase Date or the third Business Day immediately prior to the Designated Event Repurchase Date, as the case may be,

(iv) state the name and address of the Trustee, the Paying Agent and, if applicable, the Exchange Agent,

(v) state that Exchangeable Debentures must be surrendered to the Paying Agent to collect the repurchase price,

(vii) if the Exchangeable Debentures are then exchangeable, state that Exchangeable Debentures as to which a Repurchase Notice or the Designated Event Repurchase Notice, as the case may be, has been given may be exchanged only if the Repurchase Notice or Designated Event Repurchase Notice, as the case may be, is withdrawn in accordance with the terms of this Twenty-Third Supplemental Indenture,

(viii) state the amount of interest accrued and unpaid per $1,000 principal amount of Exchangeable Debentures to, but excluding, the Designated Event Repurchase Date or Repurchase Date, as the case may be,

(ix) state that, unless the Company defaults in making payment of the repurchase price, interest on Exchangeable Debentures covered by any Repurchase Notice or Designated Event Repurchase Notice, as the case may be, shall cease to accrue on and after the Designated Event Repurchase Date or the Repurchase Date, as the case may be,

(x) state the CUSIP number of the Exchangeable Debentures, if CUSIP numbers are then in use, and

(xi) state the procedures for withdrawing a Repurchase Notice or Designated Event Repurchase Notice, as the case may be, including a form of notice of withdrawal (as specified in Section 5.04).

An Issuer Repurchase Notice may be given by the Company or, at the Company’s request, the Trustee shall give such Issuer Repurchase Notice in the Company’s name and at the Company’s expense; provided that the text of the Issuer Repurchase Notice shall be prepared by the Company.

If any of the Exchangeable Debentures are represented by a Global Debenture, then the Company will modify such Issuer Repurchase Notice to the extent necessary to accord with the applicable procedures of the Depositary that apply to the repurchase of Global Debentures.

(c) The Company will, to the extent applicable, comply with the provisions of Rule 13e-4 and Rule 14e-1 (or any successor provision) under the Exchange Act that may be applicable at the time of the repurchase of the Exchangeable Debentures, file the related Schedule TO (or any successor schedule, form or report) under the Exchange Act and comply with all other applicable federal and state securities laws in connection with the repurchase of the Exchangeable Debentures.

Section 5.04 Effect of Repurchase Notice; Withdrawal. Upon receipt by the Paying Agent of the Repurchase Notice or Designated Event Repurchase Notice, as the case may be,

the Holder of the Exchangeable Debenture in respect of which such Repurchase Notice or Designated Event Repurchase Notice, as the case may be, was given shall (unless such Repurchase Notice or Designated Event Repurchase Notice is validly withdrawn in accordance with this Section 5.04) thereafter be entitled to receive solely the repurchase price with respect to such Exchangeable Debenture. Such repurchase price shall be paid to such Holder, (x) on the day set forth in Section 5.02(g), in the case of a Repurchase Notice, or (y) on the date set forth in Section 5.01(g), in the case of a Designated Event Repurchase Notice.

Exchangeable Debentures in respect of which a Repurchase Notice or Designated Event Repurchase Notice, as the case may be, has been given by the Holder thereof may not be exchanged pursuant to Article 5 hereof on or after the date of the delivery of such Repurchase Notice unless such Repurchase Notice or Designated Event Repurchase Notice, as the case may be, has first been validly withdrawn.

A Repurchase Notice or Designated Event Repurchase Notice, as the case may be, may be withdrawn in whole or in part by means of a written notice of withdrawal delivered to the office of the Paying Agent at any time prior to 5:00 p.m., New York City time, on the third Business Day immediately prior to the Designated Event Repurchase Date, or on the second Business Day immediately prior to the Repurchase Date, as the case may be, specifying:

(a) the name of the Holder;

(b) the certificate number(s) of all withdrawn Exchangeable Debentures in certificated form or that the notice of withdrawal complies with appropriate Depositary procedures with respect to all withdrawn Exchangeable Debentures represented by a Global Debenture;

(c) the principal amount of Exchangeable Debentures with respect to which such notice of withdrawal is being submitted, which must be an integral multiple of $1,000; and

(d) the principal amount of Exchangeable Debentures, if any, that remains subject to the original Repurchase Notice or Designated Event Repurchase Notice, as the case may be, and that has been or will be delivered for repurchase by the Company, which must be an integral multiple of $1,000.

Section 5.05 Deposit of Repurchase Price. (a) Prior to 11:00 a.m., New York City time, on the Designated Event Repurchase Date or the Repurchase Date, the Company shall deposit with the Paying Agent or, if the Company is acting as the Paying Agent, shall segregate and hold in trust an amount of cash (in immediately available funds if deposited on the Designated Event Repurchase Date or the Repurchase Date, as the case may be), sufficient to pay the aggregate repurchase price of all the Exchangeable Debentures or portions thereof that are to be repurchased as of the Designated Event Repurchase Date or the Repurchase Date, as the case may be.

(b) If on the Designated Event Repurchase Date or the Repurchase Date the Paying Agent holds funds sufficient to pay the repurchase price of the Debentures that Holders have elected to require the Company to repurchase in accordance with Section 5.01 or Section 5.02, as the case may be, then, on and after the Designated Event Repurchase Date or the Repurchase Date, as the case may be, such Exchangeable Debentures will cease to be outstanding, interest on such Exchangeable Debentures will cease to accrue and all other rights of the Holders of such Exchangeable Debentures will terminate, other than the right to receive the repurchase price upon delivery or book-entry transfer of the Exchangeable Debenture. This will be the case whether or not book-entry transfer of the Exchangeable Debenture has been made or the Exchangeable Debenture has been delivered to the Paying Agent.

Section 5.06 Exchangeable Debentures Repurchased in Part. Upon presentation of any Exchangeable Debenture repurchased only in part, the Company shall execute and the Trustee shall authenticate and make available for delivery to the Holder thereof, at the expense of the Company, a new Exchangeable Debenture or Exchangeable Debentures in aggregate principal amount equal to the unrepurchased portion of the Exchangeable Debentures presented (provided that the unrepurchased portion of the Exchangeable Debentures must be in an integral multiple of $1,000).

Section 5.07 Repayment to the Company. The Paying Agent shall return to the Company any cash that remains unclaimed, together with interest, if any, thereon, held by it for the payment of the repurchase price; provided that to the extent that the aggregate amount of cash deposited by the Company pursuant to Section 5.05 exceeds the aggregate repurchase price of the Exchangeable Debentures or portions thereof which the Company is obligated to repurchase as of the Designated Event Repurchase Date or the Repurchase Date, as the case may be, then, unless otherwise agreed in writing with the Company, promptly after the second Business Day following the Designated Event Repurchase Date or the Repurchase Date, as the case may be, the Paying Agent shall return any such excess to the Company, together with interest, if any, thereon.

Section 5.08 Merger, Consolidation or Sale by Host REIT. For purposes of the Exchangeable Debentures, Article 5 of the Indenture is hereby superseded. Neither the Company nor Host REIT may (1) consolidate or merge into any other Person or sell, convey, lease or transfer its properties and assets substantially as an entirety to any other Person in any one transaction or series of related transactions, or (2) permit any person to consolidate with or merge into it, unless, (a) in case of a merger or consolidation, if either the Company or Host REIT (as the case may be) is the surviving Person or if the Company or Host REIT is not the surviving Person, the surviving Person formed by such consolidation or into which the Company or Host REIT is merged or the Person to which the Company’s or Host REIT’s properties and assets are so transferred shall be a entity organized and existing under the laws of

the United States of America, any state thereof or the District of Columbia and shall execute and deliver to the Trustee a supplemental indenture expressly assuming, in the case of a transaction involving the Company, the payment when due of the principal of and interest on the Exchangeable Debentures and in the case of a transaction involving the Company or Host REIT, the performance of each of the Company’s or Host REIT’s (as the case may be) other covenants under this Twenty-Third Supplemental Indenture and the Indenture, and (b) immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing.

Section 5.09 Successor Person Substituted. Upon any consolidation or merger or any transfer of all or substantially all of the assets of the Company or Host REIT (as the case may be), in accordance with Section 5.08, the successor Person formed by such consolidation or into which the Company or Host REIT, as applicable, is merged or to which such transfer is made, shall succeed to, be substituted for, and may exercise every right and power of the Company or Host REIT, as applicable, under this Indenture with the same effect as if such successor Person had been named therein as the Company or Host REIT, as applicable, and the Company or Host REIT, as applicable, shall be released from the obligations under the Exchangeable Debentures, this Twenty-Third Supplemental Indenture and the Indenture.

ARTICLE 6

Section 6.01 Exchange Rights. (a) Subject to the restrictions on ownership of shares of Host REIT Common Stock as set forth in Section 6.12 and upon compliance with the provisions of this Twenty-Third Supplemental Indenture and the Indenture, on or prior to the close of business on the second Business Day immediately preceding the Maturity Date, the Holder of any Exchangeable Debentures not previously redeemed or repurchased shall have the right, at such Holder’s option, to exchange its Exchangeable Debentures, or any portion thereof which is a multiple of $1,000, into cash or, if applicable, cash and Host REIT Common Stock, as the case may be, with an aggregate value equal to the Exchange Value, by surrender of such Exchangeable Debentures so to be exchanged in whole or in part, together with any required funds, under the circumstances and in the manner described in this Article 6. Holders may exchange their Exchangeable Debentures at any time on or after March 15, 2027. In addition, Holders may exchange their Exchangeable Debentures at any time prior to March 15, 2027 only upon occurrence of one of the following events:

(i) Exchange Upon Satisfaction of Market Price Condition. A Holder may surrender any of its Exchangeable Debentures for exchange during any calendar quarter beginning after the calendar quarter ended June 30, 2007 (and only during such calendar quarter) if, and only if, the Closing Sale Price of the Host REIT Common Stock for at least twenty (20) Trading Days (whether or not consecutive) in the period of thirty (30) consecutive

Trading Days ending on the last Trading Day of the preceding calendar quarter is more than 130% of the Exchange Price per share of Host REIT Common Stock in effect on the applicable Trading Day. The Board of Directors of Host REIT will make appropriate adjustments, in its good faith determination, to account for any adjustment to the Exchange Rate that becomes effective, or any event requiring an adjustment to the Exchange Rate where the Ex-Dividend Date of the event occurs, during that thirty (30) consecutive Trading Day period.

The Trustee (or other Exchange Agent appointed by the Company) shall, on behalf of the Company, determine on a daily basis during the time period specified in this Section 6.01(a)(i) whether the Exchangeable Debentures shall be exchangeable as a result of the occurrence of an event specified in this clause (i) and, if the Exchangeable Debentures shall be so exchangeable, the Trustee (or other Exchange Agent appointed by the Company) shall promptly deliver to the Company and the Trustee (if the Trustee is not the Exchange Agent) written notice thereof.

(ii) Exchange Upon Satisfaction of Trading Price Condition. A Holder may surrender any of its Exchangeable Debentures for exchange during the five (5) consecutive Trading Day period following any five (5) consecutive Trading Days in which the Trading Price per $1,000 principal amount of Exchangeable Debentures (as determined following a reasonable request by a Holder of the Exchangeable Debentures) was less than 95% of the product of the Closing Sale Price of the Host REIT Common Stock during such period, multiplied by the Applicable Exchange Rate.

The Trustee shall have no obligation to determine the Trading Price of the Exchangeable Debentures unless the Company shall have requested such determination, and the Company shall have no obligation to make such request unless a Holder provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of Exchangeable Debentures would be less than 95% of the product of the Closing Sale Price per share of Host REIT Common Stock and the Exchange Rate, whereupon the Company shall instruct the Trustee to determine the Trading Price of the Exchangeable Debentures beginning on the next Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal amount of Exchangeable Debentures is greater than or equal to 95% of the product of the Closing Sale Price per share of Host REIT Common Stock and the Applicable Exchange Rate. If the Company does not, when it is obligated to, make a request to the Trustee to determine the Trading Price of the Exchangeable Debentures, or if the Company makes such request to the Trustee and the Trustee does not make such determination, then the Trading Price per $1,000 in principal amount of Exchangeable Debentures will be deemed to be less than 95% of the product of the Closing Sale Price of Host REIT Common Stock and the Applicable Exchange Rate.

(iii) Exchange Upon Notice of Redemption. A Holder may surrender for exchange any of the Exchangeable Debentures called for redemption at any time prior to the close of business on the second Business Day immediately prior to Redemption Date even if the

Exchangeable Debentures are not otherwise exchangeable at such time. The right to exchange Exchangeable Debentures pursuant to this clause (iii) shall expire after 5:00 p.m., New York City time, on the second Business Day immediately preceding the Redemption Date unless the Company defaults in payment of the Redemption Price; provided, however, that if a Holder has already delivered a Repurchase Notice with respect to an Exchangeable Debenture, such Holder may not surrender that Exchangeable Debenture for exchange until it has withdrawn such Repurchase Notice in accordance with the terms of the Exchangeable Debentures.

(iv) Exchange Upon Specified Transactions. If Host REIT elects to: (1) distribute to all holders of the Host REIT Common Stock certain rights entitling them to purchase, for a period expiring within 45 days, shares of Host REIT Common Stock at less than the Closing Sale Price of Host REIT Common Stock on the Trading Day immediately preceding the declaration date of such distribution; or (2) distribute to all holders of Host REIT Common Stock the Company’s or Host REIT’s assets, debt securities or certain rights to purchase securities of the Company or Host REIT, which distribution (excluding for this purpose a distribution solely in the form of cash required to preserve the status of Host REIT as a real estate investment trust) has a per share value exceeding 12.5% of the Closing Sale Price of the Host REIT Common Stock on the Trading Day immediately preceding the declaration date of such distribution; the Company must notify the Holders of Exchangeable Debentures at least twenty (20) calendar days prior to the Ex-Dividend Date for such distribution.

Following the issuance of such notice, Holders may surrender their Exchangeable Debentures for exchange at any time until the earlier of the close of business on the Business Day immediately preceding the Ex-Dividend Date or an announcement that such distribution will not take place; provided, however, that a Holder may not exchange its Exchangeable Debentures pursuant to this Section 6.01(a)(iv) if such Holder may participate in the distribution, without exchange of its Exchangeable Debentures, as if such Holder held on the date such distribution is made a number of shares of Host REIT Common Stock equal to a fraction the numerator of which is the product of the Exchange Rate in effect on the Ex-Dividend Date for such distribution, and the aggregate principal amount of Exchangeable Debentures held by such Holder and the denominator of which is one thousand ($1,000). The “Ex-Dividend Date” means, with respect to any distribution on shares of Host REIT Common Stock, the first date upon which a sale of the Host REIT Common Stock does not automatically transfer the right to receive the relevant distribution from the seller of the Host REIT Common Stock to its buyer.

In addition, if a Change in Control occurs prior to the stated Maturity Date as a result of a transaction or event described in (i) or (ii) of the definition of Change in Control, the Company will notify Holders (which notification may be made through a notice to DTC) as promptly as reasonably practicable following the date the Company publicly announces such transaction or event (but in no event less than twenty (20) Business Days prior to the effective time of such transaction or event). A Holder may surrender its Exchangeable Debentures for exchange at any

time from and including the date that is fifteen (15) Business Days prior to the anticipated effective time of the transaction or event up to and including (i) the related Designated Event Repurchase Date corresponding to such event or (ii) if there is no such Designated Event Repurchase Date, the date that is five (5) Business Days after the actual date of such transaction or event. If a Change in Control occurs prior to the stated Maturity Date as a result of an event described in (iii) or (iv) of the definition of Change in Control, or if a Termination in Trading occurs, the Company will notify Holders of the occurrence of any such event (which notification may be made through a notice to the DTC) and issue a press release on the Effective Date of such event. Once the Company has given such notice, a Holder may surrender its Exchangeable Debentures for exchange at any time from the Effective Date of such event until (i) the Designated Event Repurchase Date corresponding to such event or (ii) if there is no such Designated Event Repurchase Date, twenty (20) Trading Days following the Effective Date of such event.

If Host REIT is a party to a consolidation, merger, binding share exchange, reclassification or sale or conveyance of all or substantially all of its properties and assets, in each case pursuant to which all of the Host REIT Common Stock is exchanged for cash, securities or other property (the “Reference Property”), then at the effective time of the transaction any exchange of Exchangeable Debentures and the Exchange Value will be based on the kind and amount of cash, securities or other property that a Holder of Exchangeable Debentures would have received if such Holder had, immediately prior to the effective time of such transaction, exchanged its Exchangeable Debentures for a number of shares of Host REIT Common Stock equal to a fraction the numerator of which is the product of the Exchange Rate in effect immediately prior to the effective time of such transaction, and the aggregate principal amount of Exchangeable Debentures held by such Holder and the denominator of which is one thousand ($1,000). In the event holders of Host REIT Common Stock have the opportunity to elect the form of consideration to be received in any such transaction or event, then from and after the effective date of such transaction or event, the Exchangeable Debentures shall be exchangeable into cash with respect to the Principal Return and, if the Company elects to deliver property other than cash in satisfaction of the Net Amount, if any, into the consideration that a majority of the holders of Host REIT Common Stock who made such an election received in such transaction or as a result of such event with respect to the Daily Share Amounts.

(b) Whenever the Exchangeable Debentures shall become exchangeable pursuant to this Section 6.01, the Company or, at the Company’s request, the Trustee in the name and at the expense of the Company, shall notify the Holders of the event triggering such exchangeability in the manner provided in Section 13.2 of the Indenture, and the Company shall also publicly announce such information and publish it on the Host REIT’s website. Any notice so given shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice.

Designated Event Repurchase Notice or Repurchase Notice, as the case may be, exercising such Holder’s right to require the Company to repurchase such Exchangeable Debenture pursuant to Section 5.01 or 5.02 may be exchanged only if such Repurchase Notice is withdrawn in accordance with Section 5.03 or 5.04 prior to 5:00 p.m., New York City time, on the second Business Day immediately prior to the Repurchase Date or on the third Business Day immediately prior to the Designated Event Repurchase Date, as applicable.

(d) A Holder of Exchangeable Debentures is not entitled to any rights of a Holder of Host REIT Common Stock until such Holder has exchanged its Exchangeable Debentures and received upon exchange thereof shares of Host REIT Common Stock.

Section 6.02 Exercise of Exchange Right; No Adjustment for Interest or Dividends. In order to exercise the exchange right with respect to any Exchangeable Debenture in certificated form, the Company must receive at the office or agency of the Company maintained for that purpose in the City of New York or, at the option of such Holder, the Corporate Trust Office, such Exchangeable Debenture with the original or facsimile of the form entitled “Exchange Notice” on the reverse thereof, duly completed and signed manually or by facsimile, together with such Exchangeable Debentures duly endorsed for transfer, accompanied by the funds, if any, required by this Section 6.02. Such notice shall also state the name or names (with address or addresses) in which the certificate or certificates for shares of Host REIT Common Stock that shall be issuable on such exchange shall be issued, and shall be accompanied by transfer or similar taxes, if required pursuant to Section 6.06.

To exchange an Exchangeable Debenture held in book-entry form, a Holder must exchange by book-entry transfer to the Exchange Agent through the facilities of DTC and the Exchange Notice must comply with all applicable DTC procedures. To exchange an Exchangeable Debenture held in certificated form, a Holder must (i) complete and manually sign an Exchange Notice, a form of which is on the back of the Exchangeable Debenture, and deliver the Exchange Notice to the Exchange Agent; (ii) surrender the Exchangeable Debenture to the Exchange Agent’ (iii) if required by the Exchange Agent, furnish appropriate endorsement and transfer documents; and (iv) pay all required transfer or similar taxes.

Holders may also obtain copies of the required form of the Exchange Notice from the Exchange Agent. The date on which the Holder satisfies all such requirements shall be deemed to be the date on which the applicable Exchangeable Debentures shall have been tendered for exchange.

Whether the Exchangeable Debentures to be exchanged are held in book-entry or certificated form, the Exchange Notice will require the Holder to certify that it or the Person on whose behalf the Exchangeable Debentures are being exchanged is a QIB within the meaning of Rule 144A under the Securities Act.

Exchangeable Debentures in respect of which a Holder has delivered a Repurchase Notice or a Designated Event Repurchase Notice may be exchanged only if such notice is withdrawn in accordance with the terms of Section 5.03 or Section 5.04, as the case may be.

Upon surrender of an Exchangeable Debenture for exchange by a Holder, such Holder shall deliver to the Company cash equal to the amount that the Company is required to deduct and withhold under applicable law in connection with the exchange; provided, however, if the Holder does not deliver such cash, the Company may deduct and withhold from the amount otherwise deliverable to such Holder the amount required to be deducted, withheld and paid over to any governmental authority under applicable law, and any amount so deducted, withheld and paid over shall be deemed paid to such Holder for all purposes of this Indenture.

A certificate, or a book entry transfer through DTC, for the number of shares of Host REIT common stock, if any, for which any debentures are exchanged, together with a cash payment for any fractional shares, will be delivered through the exchange agent as soon as practicable, but no later than the fifth Business Day following the last day of the applicable Exchange Period.

Each exchange shall be deemed to have been effected as to any such Exchangeable Debenture (or portion thereof) on the date on which the requirements set forth above in this Section 6.02 have been satisfied as to such Exchangeable Debenture (or portion thereof) or, if later, the Determination Date (the “Exchange Date”), and the Person in whose name any certificate or certificates for shares of Host REIT Common Stock shall be issuable upon such exchange shall be deemed to have become on said date the holder of record of the shares represented thereby; provided that any such surrender on any date when the stock transfer books of Host REIT shall be closed shall constitute the Person in whose name the certificates are to be issued as the record holder thereof for all purposes on the next succeeding day on which such stock transfer books are open, but such exchange shall be at the Exchange Rate in effect on the Exchange Date.

Any Exchangeable Debenture or portion thereof surrendered for exchange during the period from 5:00 p.m., New York City time, on the Record Date for any interest payment date to 5:00 p.m., New York City time, on the applicable interest payment date shall be accompanied by payment, in immediately available funds or other funds acceptable to the Company, of an amount equal to the interest otherwise payable on such interest payment date on the principal amount being exchanged; provided that no such payment need be made (1) if a Holder exchanges its Exchangeable Debentures in connection with a redemption and the Company has specified a Redemption Date that is after a Record Date and on or prior to the Business Day immediately succeeding the next interest payment date, (2) if a Holder exchanges its Exchangeable Debentures in connection with a Designated Event and the Company has specified a Designated Event Repurchase Date that is after a Record Date and on or prior to the corresponding interest payment date or (3) to the extent of any overdue interest, if any overdue interest exists at the time of exchange with respect to such Exchangeable Debenture. Except as

otherwise provided above in this Article 6, no payment or other adjustment shall be made for interest accrued on any Exchangeable Debenture exchanged or for dividends on any shares issued upon the exchange of such Exchangeable Debenture as provided in this Article 6. Notwithstanding the foregoing, in the case of Exchangeable Debentures submitted for exchange in connection with a Designated Event, such Exchangeable Debentures shall continue to represent the right to receive the Additional Change in Control Shares, if any, payable pursuant to Section 6.11, until such Additional Change in Control Shares are so paid.

Upon the exchange of an interest in a Global Debenture, the Trustee (or other Exchange Agent appointed by the Company), or the Custodian at the direction of the Trustee (or other Exchange Agent appointed by the Company), shall make a notation on such Global Debenture as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any exchanges of Exchangeable Debentures effected through any Exchange Agent other than the Trustee.

Upon an exchange of an Exchangeable Debenture, a Holder will not receive any cash payment of interest, except as described herein, and the Company will not adjust the Exchange Rate to account for accrued and unpaid interest. Upon the exchange of an Exchangeable Debenture, the accrued but unpaid interest attributable to the period from the issue date of the Exchangeable Debenture to the Exchange Date, with respect to the exchanged Exchangeable Debenture, shall not be deemed canceled, extinguished or forfeited, but rather shall be deemed to be paid in full to the Holder thereof through delivery of cash and, if applicable, shares of Host REIT Common Stock (together with the cash payment, if any in lieu of fractional shares) in exchange for the Exchangeable Debenture being exchanged pursuant to the provisions hereof.

In case any Exchangeable Debenture of a denomination greater than $1,000 shall be surrendered for partial exchange, and subject to Section 2.3 of the Indenture, the Company shall execute and the Trustee shall authenticate and deliver to the Holder of the Exchangeable Debenture so surrendered, without charge to the Holder, a new Exchangeable Debenture or Exchangeable Debentures in authorized denominations in an aggregate principal amount equal to the unexchanged portion of the surrendered Exchangeable Debenture.

Section 6.03 Cash Payments in Lieu of Fractional Shares. No fractional shares of Host REIT Common Stock or scrip certificates representing fractional shares shall be issued upon exchange of Exchangeable Debentures. If more than one Exchangeable Debenture shall be surrendered for exchange at one time by the same Holder, the number of full shares that shall be issuable upon exchange shall be computed on the basis of the aggregate principal amount of the Exchangeable Debentures (or specified portions thereof to the extent permitted hereby) so surrendered. If any fractional share of Host REIT Common Stock would be issuable upon the exchange of any Exchangeable Debenture or Exchangeable Debentures, the Company shall make an adjustment and payment therefor in cash to the Holder of Exchangeable Debentures at a price equal to the Average Price.

Section 6.04 Exchange Rate. The initial Exchange Rate for the Exchangeable Debentures is 31.0020 shares of Host REIT Common Stock per each $1,000 principal amount of the Exchangeable Debentures, subject to adjustment as provided in Sections 6.05 and 6.11 (herein called the “Exchange Rate”).

Section 6.05 Adjustment of Exchange Rate. The Exchange Rate shall be adjusted from time to time by the Company as follows:

(a) If Host REIT issues the Host REIT Common Stock as a dividend or distribution on the Host REIT Common Stock to all holders of Host REIT Common Stock, or if Host REIT effects a share split or share combination, the Exchange Rate will be adjusted based on the following formula:

ER₁ = ER₀ x OS₁/OS₀

where

ER₀ = the Exchange Rate in effect immediately prior to the Ex-Dividend Date for such dividend or distribution, or the effective date of such share split or share combination;

ER₁ = the new Exchange Rate in effect immediately after the Ex-Dividend Date for such dividend or distribution, or the effective date of such share split or share combination;

OS₀ = the number of shares of Host REIT Common Stock outstanding immediately prior to such dividend or distribution, or the effective date of such share split or share combination; and

OS₁ = the number of shares of Host REIT Common Stock outstanding immediately after such dividend or distribution, or the effective date of such share split or share combination.

Any adjustment made pursuant to this paragraph (a) shall become effective on the date that is immediately after (x) the Ex-Dividend Date for such dividend or other distribution or (y) the date on which such split or combination becomes effective, as applicable. If any dividend or distribution described in this paragraph (a) is declared but not so paid or made, the new Exchange Rate shall be readjusted to the Exchange Rate that would then be in effect if such dividend or distribution had not been declared.

(b) If Host REIT distributes to all holders of Host REIT Common Stock any rights, warrants or options entitling them for a period of not more than forty-five (45) days after the date of issuance thereof to subscribe for or purchase Host REIT Common Stock for a period of not more than forty-five (45) days after the date of issuance thereof, in either case at an exercise price per share of Host REIT Common Stock less than the Closing Sale Price of the

Host REIT Common Stock on the Business Day immediately preceding the time of announcement of such issuance, the Exchange Rate will be adjusted based on the following formula:

ER₁ = ER₀ x (OS₀+ X)/(OS₀+ Y)

where

ER₀ = the Exchange Rate in effect immediately prior to the Ex-Dividend Date for such distribution;

ER₁ = the new Exchange Rate in effect immediately after the Ex-Dividend Date for such distribution;

OS₀ = the number of shares of Host REIT Common Stock outstanding immediately prior to the Ex-Dividend Date for such distribution;

X = the total number of shares of Host REIT Common Stock issuable pursuant to such rights, warrants or options; and

Y = the number of shares of Host REIT Common Stock equal to the quotient of (A) the aggregate price payable to exercise such rights, warrants or options and (B) the average of the Closing Sale Prices of the Host REIT Common Stock for the ten (10) consecutive Trading Days ending on the Business Day immediately preceding the date of announcement for the issuance of such rights, warrants or options.

For purposes of this paragraph (b), in determining whether any rights, warrants or options entitle the holders to subscribe for or purchase Host REIT Common Stock at less than the applicable Closing Sale Price of the Host REIT Common Stock, and in determining the aggregate exercise or exchange price payable for such Host REIT Common Stock, there shall be taken into account any consideration received by Host REIT for such rights, warrants or options and any amount payable on exercise or exchange thereof, with the value of such consideration, if other than cash, to be determined by Host REIT’s Board of Directors. If any right, warrant or option described in this paragraph (b) is not exercised or exchanged prior to the expiration of the exerciseability or exchangeability thereof, the new Exchange Rate shall be readjusted to the Exchange Rate that would then be in effect if such right, warrant or option had not been so issued.

(c) If Host REIT distributes capital stock, evidences of indebtedness or other assets or property of Host REIT to all holders of Host REIT Common Stock, excluding:

(i) dividends, distributions, rights, warrants or options referred to in paragraph (a) or (b) above;

(ii) dividends or distributions paid exclusively in cash; and

(iii) Spin-Offs described below in this paragraph (c),

then the Exchange Rate will be adjusted based on the following formula:

ER₁ = ER₀ x SP₀/(SP₀ - FMV)

where

ER₀ = the Exchange Rate in effect immediately prior to the Ex-Dividend Date for such distribution;

ER₁ = the new Exchange Rate in effect immediately after the Ex-Dividend Date for such distribution;

SP₀= the average of the Closing Sale Prices of the Host REIT Common Stock for the ten (10) consecutive Trading Days prior to the Business Day immediately preceding the earlier of the record date or the Ex-Dividend Date for such distribution; and

FMV = the fair market value (as determined in good faith by the Host REIT Board of Directors) of the shares of capital stock, evidences of indebtedness, assets or property distributed with respect to each outstanding share of Host REIT Common Stock on the earlier of the record date or the Ex-Dividend Date for such distribution;

provided that if “FMV” with respect to any distribution of shares of capital stock, evidences of indebtedness or other assets or property of Host REIT is equal to or greater than “SP₀” with respect to such distribution, then in lieu of the foregoing adjustment, adequate provision shall be made so that each holder of Exchangeable Debentures shall have the right to receive on the date such shares of capital stock, evidences of indebtedness or other assets or property of Host REIT are distributed to holders of Host REIT Common Stock, for each Exchangeable Debenture, the amount of shares of capital stock, evidences of indebtedness or other assets or property of Host REIT such holder of Exchangeable Debentures would have received had such holder of Exchangeable Debentures owned a number of shares of Host REIT Common Stock equal to a fraction the numerator of which is the product of the Exchange Rate in effect on the Ex-Dividend Date for such distribution, and the aggregate principal amount of Exchangeable Debentures held by such Holder and the denominator of which is one thousand ($1,000).

An adjustment to the Exchange Rate made pursuant to the immediately preceding paragraph shall be made successively whenever any such distribution is made and shall become effective on the Ex-Dividend Date for such distribution.

If Host REIT distributes to all holders of Host REIT Common Stock capital stock of any class or series, or similar equity interest, of or relating to a subsidiary or other business unit of Host REIT (a “Spin-Off”), the Exchange Rate in effect immediately before the tenth Trading Day from and including the effective date of the Spin-Off will be adjusted based on the following formula:

ER₁ = ER₀ x (FMV₀ + MP₀)/MP₀

where

ER₀ = the Exchange Rate in effect immediately prior to the tenth Trading Day from, and including, the effective date of the Spin-Off;

ER₁ = the new Exchange Rate immediately after the tenth Trading Day from, and including, the effective date of the Spin-Off;

FMV₀ = the average of the Closing Sale Prices of the capital stock or similar equity interest distributed to holders of Host REIT Common Stock applicable to one share of Host REIT Common Stock over the first ten (10) consecutive Trading Days after the effective date of the Spin-Off; and

MP₀ = the average of the Closing Sale Prices of the Host REIT Common Stock over the first ten (10) consecutive Trading Days after the effective date of the Spin-Off.

An adjustment to the Exchange Rate made pursuant to the immediately preceding paragraph will occur on the tenth Trading Day from and including the effective date of the Spin-Off; provided that in respect of any exchange within the ten (10) Trading Days following the effective date of any Spin-Off, references within this paragraph (c) to ten (10) Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between the effective date of such Spin-Off and the Exchange Date in determining the Applicable Exchange Rate.

If any such dividend or distribution described in this paragraph (c) is declared but not paid or made, the new Exchange Rate shall be readjusted to be the Exchange Rate that would then be in effect if such dividend or distribution had not been declared.

(d) If Host REIT makes any cash dividend or distribution to all holders of outstanding Host REIT Common Stock (excluding any dividend or distribution in connection with the liquidation, dissolution or winding up of Host REIT) during any calendar quarter in an

amount per share that, together with other cash dividends or distributions made during such calendar quarter exceeds $0.20 (the “Reference Dividend”), the Exchange Rate will be adjusted based on the following formula:

ER₁ = ER₀ x SP₀ /(SP₀ - C)

where

ER₀ = the Exchange Rate in effect immediately prior to the Ex-Dividend Date for such distribution;

ER₁ = the new Exchange Rate immediately after the Ex-Dividend Date for such distribution;

SP₀ = the average of the Closing Sale Prices of the Host REIT Common Stock for the ten (10) consecutive Trading Days prior to the Business Day immediately preceding the earlier of the record date or the day prior to the Ex-Dividend Date for such distribution; and

C = the aggregate amount in cash per share that Host REIT distributes to holders of Host REIT Common Stock in a calendar quarter that exceeds the Reference Dividend;

provided that if “C” with respect to any such cash dividend or distribution is equal to or greater than “SP₀” with respect to any such cash dividend or distribution, then in lieu of the foregoing adjustment, adequate provision shall be made so that each holder of Exchangeable Debentures shall have the right to receive on the date such cash is distributed to holders of Host REIT Common Stock, for each Exchangeable Debenture, the amount of cash such holder of Exchangeable Debentures would have received had such holder of Exchangeable Debentures owned a number of shares of Host REIT Common Stock equal to a fraction the numerator of which is the product of the Exchange Rate in effect on the Ex-Dividend Date for such dividend or distribution, and the aggregate principal amount of Exchangeable Debentures held by such Holder and the denominator of which is one thousand ($1,000).

Notwithstanding the foregoing, the Exchange Rate will only be adjusted for that portion of the adjustment required by this paragraph (d) for which no adjustment to the Exchange Rate has yet been made.

An adjustment to the Exchange Rate made pursuant to this paragraph (d) shall become effective on the Ex-Dividend Date for such dividend or distribution. If any dividend or distribution described in this paragraph (d) is declared but not so paid or made, the new Exchange Rate shall be readjusted to the Exchange Rate that would then be in effect if such dividend or distribution had not been declared.

The Reference Dividend shall be subject to adjustment on account of any of the events set forth

in paragraphs (a), (b) and (c) above and paragraph (e) below. Any such adjustment will be effected by multiplying the Reference Dividend by a fraction, the numerator of which will equal the Exchange Rate in effect immediately prior to the adjustment on account of such event and the denominator of which will equal the Exchange Rate as adjusted.

(e) If Host REIT or any of its Subsidiaries makes a payment in respect of a tender offer or exchange offer for Host REIT Common Stock to the extent that the cash and value of any other consideration included in the payment per share of Host REIT Common Stock exceeds the Closing Sale Price of a share of Host REIT Common Stock on the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender offer or exchange offer (the “Expiration Time”), the Exchange Rate will be adjusted based on the following formula:

ER₁ = ER₀ x (AC + (SP₁ x OS₁))/(SP₁ x OS₀)

where

ER₀ = the Exchange Rate in effect at the close of business on the last Business Day of the ten (10) consecutive Trading Day period commencing on the Trading Day next succeeding the date such tender offer or exchange offer expires;

ER₁ = the new Exchange Rate in effect immediately following the last Business Day of the ten (10) consecutive Trading Day period commencing on the Trading Day next succeeding the date such tender offer or exchange offer expires;

AC = the aggregate value of all cash and any other consideration (as determined by Host REIT’s Board of Directors) paid or payable for the Host REIT Common Stock purchased in such tender or exchange offer;

OS₀ = the number of shares of Host REIT Common Stock outstanding immediately prior to the date such tender offer or exchange offer expires;

OS₁ = the number of shares of Host REIT Common Stock outstanding immediately after the date such tender or exchange offer expires (after giving effect to the purchase or exchange of shares of Host REIT Common Stock pursuant to such tender offer or exchange offer); and

SP₁ = the average of the Closing Sales Prices of the Host REIT Common Stock for the ten (10) consecutive Trading Day next succeeding the date such tender offer or exchange offer expires.

If the application of the foregoing formula would result in a decrease in the Exchange Rate, no adjustment to the Exchange Rate will be made.

Any adjustment to the Exchange Rate made pursuant to this paragraph (e) will occur on the tenth Trading Day from and including the Trading Day next succeeding the Effective Date of the tender offer or exchange offer; provided that in respect of any exchange within the ten (10) Trading Days following the Trading Day next succeeding the Effective Date of the tender offer or exchange offer, references within this paragraph (e) to ten (10) Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between Trading Day next succeeding the Effective Date of such tender offer or exchange offer and the exchange date in determining the Applicable Exchange Rate. If Host REIT or one of its Subsidiaries is obligated to purchase Host REIT Common Stock pursuant to any such tender offer or exchange offer but is permanently prevented by applicable law from effecting any such purchase or all such purchases are rescinded, the new Exchange Rate shall be readjusted to be the Exchange Rate that would be in effect if such tender offer or exchange offer had not been made.

(f) If Host REIT has in effect a stockholder’s rights plan while any Exchangeable Debentures remain outstanding, Holders of Exchangeable Debentures will receive, upon an exchange of Exchangeable Debentures in respect of which the Company elects to deliver any Net Shares, in addition to such Net Shares, rights under Host REIT ‘s stockholder rights plan unless, prior to exchange, the rights have expired, terminated or been redeemed or unless the rights have separated from the Host REIT Common Stock. If the rights provided for in the stockholder’s rights plan adopted by Host REIT have separated from the Host REIT Common Stock in accordance with the provisions of the applicable stockholder rights agreement so that Holders of Exchangeable Debentures would not be entitled to receive any rights in respect of any Net Shares, if any, that the Company elects to deliver upon an exchange of Exchangeable Debentures, the Exchange Rate will be adjusted at the time of separation as if Host REIT had distributed, to all holders of Host REIT Common Stock, capital stock, evidences of indebtedness or other assets or property pursuant to paragraph (c) above, subject to readjustment upon the subsequent expiration, termination or redemption of the rights.

(g) Notwithstanding anything in this Section 6.05, in no event will the Exchange Rate exceed one hundred (100) shares of Host REIT Common Stock per $1,000 principle amount of Exchangeable Debentures (the “Maximum Exchange Rate”), other than as a result of proportional adjustments to the Exchange Rate, pursuant to clauses (a), (b) and (c) above.

(h) In addition to the adjustments pursuant to paragraphs (a) through (e) above, the Company may increase the Exchange Rate in order to avoid or diminish any income tax to holders of Host REIT Common Stock resulting from any dividend or distribution of capital stock (or rights to acquire Host REIT Common Stock) or from any event treated as such for income tax purposes. The Company may also, from time to time, to the extent permitted by applicable law, increase the Exchange Rate by any amount for any period if the Company has determined that such increase would be in the best interests of the Company or Host REIT. If the Company makes such determination, it will be conclusive and the Company will mail to

Holders of the Exchangeable Debentures a notice of the increased Exchange Rate and the period during which it will be in effect at least fifteen (15) days prior to the date the increased Exchange Rate takes effect in accordance with applicable law.

(i) The Company shall not make any adjustment to the Exchange Rate if Holders of the Exchangeable Debentures participate in the dividend, distribution or transaction that would otherwise result in an adjustment to the Exchange Rate at the same time as holders of the Host REIT Common Stock and as if such Holders of Exchangeable Debentures owned a number of shares of Host REIT Common Stock equal to a fraction the numerator of which is the product of the Exchange Rate in effect on the Ex-Dividend Date or effective date for the relevant dividend, distribution or transaction, and the aggregate principal amount of Exchangeable Debentures held by such Holder and the denominator of which is one thousand ($1,000).

(j) In addition to the other events set forth herein on account of which no adjustment to the Exchange Rate shall be made, the Applicable Exchange Rate shall not be adjusted for:

(i) the issuance of any Host REIT Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on securities of the Company or those of Host REIT and the investment of additional optional amounts in the Host REIT Common Stock under any plan;

(ii) the issuance of any Host REIT Common Stock or options or rights to purchase those shares pursuant to any present or future employee, director, trustee or consultant benefit plan, employee agreement or arrangement or program of the Company or Host REIT;

(iii) the issuance of any Host REIT Common Stock pursuant to any option, warrant, right, or exercisable, exchangeable or exchangeable security outstanding as of the date the Exchangeable Debentures were first issued;

(iv) a change in the par value of the Host REIT Common Stock;

(v) accumulated and unpaid dividends or distributions;

(vi) as a result of a tender offer solely to holders of fewer than one hundred (100) shares of Host REIT Common Stock; and

(vii) the issuance of OP Units by the Company and the issuance of Host REIT Common Stock or the payment of cash upon redemption thereof.

(k) No adjustment in the Exchange Rate will be required unless the

adjustment would require an increase or decrease of at least 1% of the Exchange Rate. If the adjustment is not made because the adjustment does not change the Exchange Rate by at least 1%, then the adjustment that is not made will be carried forward and taken into account in any future adjustment. All required calculations will be made to the nearest cent or 1/1000th of a share, as the case may be. Notwithstanding the foregoing, the Company will make any unmade adjustments, regardless of whether the aggregate adjustment is less than 1%, (i) on the date that the Exchangeable Debentures are called for redemption and (ii) on each date thereafter and at maturity of the Exchangeable Debentures.

(l) Whenever the Exchange Rate is adjusted as herein provided, Host REIT or the Company shall as promptly as reasonably practicable file with the Trustee and any Exchange Agent other than the Trustee an Officers’ Certificate setting forth the Exchange Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Promptly after delivery of such certificate, Host REIT or the Company shall prepare a notice of such adjustment of the Exchange Rate setting forth the adjusted Exchange Rate and the date on which each adjustment becomes effective and shall mail such notice of such adjustment of the Exchange Rate to the Holders of the Exchangeable Debentures within twenty (20) Business Days of the Effective Date of such adjustment. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

(m) For purposes of this Section 6.05, the number of shares of Host REIT Common Stock at any time outstanding shall not include shares held in the treasury of Host REIT but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Host REIT Common Stock.

(n) If any of the following events occur, namely (i) any reclassification or change of the outstanding Host REIT Common Stock (other than a subdivision or combination to which Section 6.05(a) applies), (ii) any consolidation, merger or combination of Host REIT with another Person, or a binding share exchange in respect of all of the outstanding Host REIT Common Stock as a result of which holders of Host REIT Common Stock shall be entitled to receive stock, other securities or other property or assets (including cash) with respect to or in exchange for such the Host REIT Common Stock or (iii) any sale or conveyance of all or substantially all of the properties and assets of Host REIT to any other Person as a result of which holders of Host REIT Common Stock shall be entitled to receive stock, other securities or other property or assets (including cash) with respect to or in exchange for such the Host REIT Common Stock, then Host REIT or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the Trust Indenture Act as in force at the date of execution of such supplemental indenture). Such supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Section 6.05. Host REIT shall cause notice of the execution of such supplemental indenture to be mailed to each Holder of Debentures within twenty (20) Business Days after execution thereof. Failure to deliver such notice shall not affect

the legality or validity of such supplemental indenture. The provisions of this paragraph shall similarly apply to successive reclassifications, changes, consolidations, mergers, combinations, sales and conveyances. If the provisions of this paragraph apply to any event or occurrence, then the provisions of Sections 6.05(a) through (n) shall not apply.

Section 6.06 Taxes on Shares Issued. The issue of stock certificates if any, on exchange of Exchangeable Debentures shall be made without charge to the exchanging Holder for any documentary, stamp or similar issue or transfer tax in respect of the issue thereof. The Company shall not, however, be required to pay any such tax which may be payable in respect of any transfer involved in the issue and delivery of stock in any name other than that of the holder of any Exchangeable Debenture exchanged, and the Company shall not be required to issue or deliver any such stock certificate unless and until the Person or Persons requesting the issue thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid.

Section 6.07 [Intentionally Left Blank]

Section 6.08 Responsibility of Trustee. The Trustee and any other Exchange Agent shall not at any time be under any duty or responsibility to any holder of Exchangeable Debentures to determine the Exchange Rate or whether any facts exist which may require any adjustment of the Exchange Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other Exchange Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Host REIT Common Stock, or of any capital stock, other securities or other assets or property, which may at any time be issued or delivered upon the exchange of any Exchangeable Debenture; and the Trustee and any other Exchange Agent make no representations with respect thereto. Neither the Trustee nor any Exchange Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Host REIT Common Stock or stock certificates or other securities or property or cash upon the surrender of any Exchangeable Debenture for the purpose of exchange or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article 6. Without limiting the generality of the foregoing, neither the Trustee nor any Exchange Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 6.05 relating either to the kind or amount of shares of capital stock or other securities or other assets or property (including cash) receivable by Holders upon the exchange of their Exchangeable Debentures after any event referred to in such Section 6.05 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 7.1 of the Indenture, may accept as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officers’ Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such

supplemental indenture) with respect thereto. The Trustee shall not at any time be under any duty or responsibility to any holder of Exchangeable Debentures to determine the accuracy of the method employed in calculating the Trading Price or whether any facts exist which may require any adjustment of the Trading Price.

Section 6.09 Notice to Holders Prior to Certain Actions. In case:

(a) Host REIT shall declare a dividend (or any other distribution) on the Host REIT Common Stock that would require an adjustment in the Exchange Rate pursuant to Section 6.05; or

(b) Host REIT shall authorize the granting to the holders of all or substantially all of the Host REIT Common Stock of rights or warrants to subscribe for or purchase any share of any class or any other rights or warrants; or

(c) of any reclassification or reorganization of the Host REIT Common Stock (other than a subdivision or combination of its outstanding Host REIT Common Stock, or a change in par value, or from par value to no par value, or from no par value to par value), or of any consolidation, combination, merger or share exchange to which the Company or Host REIT is a party and for which approval of any stockholders of Host REIT is required, or of the sale or transfer of all or substantially all of the assets of Host REIT; or

(d) of the voluntary or involuntary dissolution, liquidation or winding up of Host REIT;

the Company shall cause to be filed with the Trustee and to be mailed to each holder of Exchangeable Debentures at its address appearing on the Exchangeable Debenture Register provided for in Section 2.4 of the Indenture, as promptly as possible but in any event at least ten (10) calendar days prior to the applicable date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution or rights or warrants, or, if a record is not to be taken, the date as of which the holders of Host REIT Common Stock of record to be entitled to such dividend, distribution or rights are to be determined, or (y) the date on which such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding up is expected to become effective or occur, and the date as of which it is expected that holders of Host REIT Common Stock of record shall be entitled to exchange their Host REIT Common Stock for securities or other property deliverable upon such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such dividend, distribution, reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding up.

Section 6.10 Settlement upon Exchange. (a) Upon exchange of any Exchangeable

Debentures, subject to Sections 6.01, 6.02 and this Section 6.10, the Company shall satisfy its obligation upon exchange (the “Exchange Obligation”) by payment and delivery of cash and, if applicable as provided herein, shares of Host REIT Common Stock for each $1,000 aggregate principal amount of Exchangeable Debentures tendered for exchange in accordance with their terms.

(b) Upon exchange of Exchangeable Debentures, the Company will deliver, in respect of each $1,000 principal amount of Exchangeable Debentures tendered for exchange in accordance with their terms:

(i) cash in an amount (the “Principal Return”) equal to the lesser of (A) the aggregate principal amount of the Exchangeable Debentures to be exchanged and (B) the aggregate Exchange Value of the Exchangeable Debentures to be exchanged;

(ii) if the Exchange Value is greater than the Principal Return, an amount (the “Net Amount”), at the election of the Company, in cash (the “Net Cash Amount”), shares of Host REIT Common Stock (the “Net Shares”) determined pursuant to Section 6.10(c), or a combination of cash and shares of Host REIT Common Stock with an aggregate value equal to the difference between the Exchange Value and the Principal Return; and

(iii) an amount in cash in lieu of any fractional shares of Host REIT Common Stock deliverable in connection with payment of the Net Shares based upon the Average Price.

(c) The Net Shares to be delivered pursuant to Section 6.10(b) will be equal to the sum of the Daily Share Amounts for each Trading Day during the Applicable Exchange Period as to which the Company has elected to deliver shares.

(d) The Exchange Value, Principal Return, Net Amount, Net Cash Amount and the number of Net Shares, as applicable, will be determined by the Issuer promptly after the end of the Applicable Exchange Period (the “Determination Date”).

(e) Payment of the Principal Return and cash in lieu of fractional shares, and delivery of the Net Shares or payment of the Net Cash Amount, as applicable, shall be made by the Company as promptly as practicable following the Determination Date, but in no event later than five Business Days thereafter (the “Exchange Settlement Date”) to the Holder of an Exchangeable Debenture surrendered for exchange, or such Holder’s nominee or nominees, and issue, or cause to be issued, and deliver to the Exchange Agent or to such Holder, or such Holder’s nominees, certificates or a book-entry transfer through the Depositary for the number of full shares of Host REIT Common Stock equal to the Net Shares, if any, to which such Holder shall be entitled as part of such Exchange Obligation.

Section 6.11 Exchange Rate Adjustment After Certain Change in Control Transactions.

(a) Subject to the provisions hereof, if a Holder elects to exchange its Exchangeable Debentures following the occurrence of the Effective Date of a Change in Control described in clause (i) or (ii) of the definition of Change in Control that occurs prior to April 15, 2012, the Company will increase the Applicable Exchange Rate for the Debentures so surrendered for exchange by a number of additional shares of Host REIT Common Stock (the “Additional Change in Control Shares”) as specified below; provided that the Additional Change in Control Shares will only be payable as set forth below. An exchange of Exchangeable Debentures will be deemed for these purposes to be “in connection with” such a Change in Control if the Exchange Notice is received by the Exchange Agent on or after the date that is fifteen (15) Business Days prior to the anticipated Effective Date of the Change in Control or on or prior to the related Repurchase Date corresponding to such event or, if there is no such Designated Event Repurchase Date, the fifth Business Day following the Effective Date of the Change in Control.

(b) The number of Additional Change in Control Shares will be determined by reference to the table in paragraph (e) below and is based on the date on which the relevant Change in Control transaction becomes effective (the “Effective Date”) and the price (the “Stock Price”) paid per share of Host REIT Common Stock in such transaction. If the holders of Host REIT Common Stock receive only cash in the relevant Change in Control transaction, the Stock Price will equal the cash amount paid per share of Host REIT Common Stock. In all other cases, the Stock Price will equal the average of the Closing Sale Prices of the Host REIT Common Stock on the ten (10) consecutive Trading Days up to but excluding the Effective Date.

(c) The Stock Prices set forth in the first row of the table below shall be adjusted as of any date on which the Exchange Rate of the Exchangeable Debentures is adjusted pursuant to Section 6.05. The adjusted Stock Prices will equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, (i) the numerator of which is the Exchange Rate immediately prior to the adjustment giving rise to the Stock Price adjustment and (ii) the denominator of which is the Exchange Rate as so adjusted.

(d) The number of Additional Change in Control Shares will be adjusted in the same manner and for the same events as the Exchange Rate is adjusted pursuant to Section 6.05.

(e) The following table sets forth the Stock Price and number of Additional Change in Control Shares issuable per $1,000 principal amount of Exchangeable Debentures:


	Stock Price
Effective date	$26.88	$27.00	$28.00	$29.00	$30.00	$35.00	$40.00	$45.00	$50.00	$75.00
March 23, 2007	5.64	5.55	4.84	4.20	3.64	1.65	0.58	0.06	0.00	0.00
April 15, 2008	5.97	5.87	5.12	4.45	3.86	1.79	0.71	0.20	0.03	0.00
April 15, 2009	6.05	5.95	5.15	4.45	3.83	1.71	0.64	0.16	0.02	0.00
April 15, 2010	6.06	5.95	5.09	4.34	3.68	1.49	0.49	0.09	0.01	0.00
April 15, 2011	5.98	5.86	4.88	4.04	3.31	1.07	0.25	0.03	0.00	0.00
April 20, 2012	6.20	6.04	4.71	3.48	2.33	0.00	0.00	0.00	0.00	0.00

(f) If the exact Stock Price and Effective Date are not set forth on the table above, then:

(i) if the Stock Price is between two Stock Prices in the table or the Effective Date is between two Effective Dates in the table, the number of Additional Change in Control Shares will be determined by a straight-line interpolation between the number of Additional Change in Control Shares set forth for the higher and lower Stock Prices and the earlier and later Effective Dates, as applicable, based on a 365-day year;

(ii) if the Stock Price is in excess of $75.00 per share of Host REIT Common Stock (the “Make Whole Cap”) no Additional Change in Control Shares will be issued upon exchange; and

(iii) if the Stock Price is less than $26.88 per share of Host REIT Common Stock (the “Make Whole Floor”) no Additional Change in Control Shares will be issued upon exchange.

Notwithstanding the foregoing, in no event will the total number of shares of Host REIT Common Stock issuable upon exchange exceed 37.2024 per $1,000 principal amount of Exchangeable Debentures, subject to adjustment in the same manner as the Exchange Rate as set forth in Section 6.05.

The Make Whole Cap and Make Whole Floor shall be adjusted as of any date on which the Exchange Rate of the Exchangeable Debentures is adjusted pursuant to Section 6.05. The adjusted Make Whole Cap or Make Whole Floor, as the case may be, shall equal the Make Whole Cap or Make Whole Floor, as the case may be, applicable immediately prior to such adjustment, multiplied by a fraction, (i) the numerator of which is the Exchange Rate immediately prior to the adjustment giving rise to the adjustment and (ii) the denominator of which is the Exchange Rate as so adjusted.

Section 6.12 Ownership Limit. (a) Notwithstanding any other provision of the Exchangeable Debentures, no Holders of Exchangeable Debentures shall be entitled to receive

shares of Host REIT Common Stock upon an exchange of Exchangeable Debentures to the extent that receipt of such shares would cause such Holder (together with such Holder’s Affiliates) to exceed the ownership limit contained in the Charter of Host REIT.

(b) At the Maturity Date or upon earlier redemption or repurchase of the Exchangeable Debentures or at any other time a payment is made with respect to the Exchangeable Debentures, and as otherwise required by law, the Company may deduct and withhold from the amount otherwise deliverable to the Holder, and pay over to the applicable governmental authority, the amount required to be deducted and withheld under applicable law, and any amount so deducted, withheld and paid over shall be deemed paid to such Holder for all purposes of this Indenture.

Section 6.13 Calculation in Respect of Debentures. Except as otherwise specifically stated herein or in the Exchangeable Debentures, all calculations to be made in respect of the Exchangeable Debentures shall be the obligation of the Company. All calculations made by the Company or its agent as contemplated pursuant to the terms hereof and of the Exchangeable Debentures shall be made in good faith and be final and binding on the Exchangeable Debentures and the Holders of the Exchangeable Debentures absent manifest error. The Company shall provide a schedule of calculations to the Trustee, and the Trustee shall be entitled to rely upon the accuracy of the calculations by the Company without independent verification. The Trustee shall forward calculations made by the Company to any Holder of Exchangeable Debentures upon request.

ARTICLE 7

Section 7.01 For purposes of the Exchangeable Debentures, Section 2.7 of the Indenture is hereby supplemented with, and where inconsistent replaced by, the following provisions:

(a) Exchange and Registration of Transfer of Exchangeable Debentures; Restrictions on Transfer. The Company shall cause to be kept at the Corporate Trust Office a register (the register maintained in such office and in any other office or agency of the Company herein sometimes collectively referred to as the “Exchangeable Debenture Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Exchangeable Debentures and of transfers of Exchangeable Debentures. The Exchangeable Debenture Register shall be in written form or in any form capable of being exchanged into written form within a reasonably prompt period of time. The Trustee is hereby appointed “Exchangeable Debenture Registrar” for the purpose of registering Exchangeable Debentures and transfers of Exchangeable Debentures as herein provided.

Upon surrender for registration of transfer of any Exchangeable Debenture to the Exchangeable Debenture Registrar or any co-registrar, and satisfaction of the requirements for such transfer, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the

designated transferee or transferees, one or more new Exchangeable Debentures of any authorized denominations and of a like aggregate principal amount and bearing such restrictive legends as may be required by this Twenty-Third Supplemental Indenture.

Exchangeable Debentures may be exchanged for other Exchangeable Debentures of any authorized denominations and of a like aggregate principal amount, upon surrender of the Exchangeable Debentures to be exchanged at any such office or agency maintained by the Company. Whenever any Exchangeable Debentures are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Exchangeable Debentures which the Holder making the exchange is entitled to receive bearing registration numbers not contemporaneously outstanding.

All Exchangeable Debentures issued upon any registration of transfer or exchange of Exchangeable Debentures shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Twenty-Third Supplemental Indenture, as the Exchangeable Debentures surrendered upon such registration of transfer or exchange.

All Exchangeable Debentures presented or surrendered for registration of transfer or for exchange, redemption, or repurchase shall (if so required by the Company or the Exchangeable Debenture Registrar) be duly endorsed, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Company, and the Exchangeable Debentures shall be duly executed by the Holder thereof or its attorney duly authorized in writing.

No service charge shall be made to any Holder for any registration of, transfer or exchange of Exchangeable Debentures, but the Company may require payment by the Holder of a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Exchangeable Debentures.

In the event of any redemption in part, the Company shall not be required to: (i) issue or register the transfer or exchange of any Exchangeable Debenture during a period beginning at the opening of business 15 days before any selection of Exchangeable Debentures for redemption and ending at the close of business on the earliest date on which the relevant notice of redemption is deemed to have been given to all Holders of Exchangeable Debentures to be so redeemed, or (ii) register the transfer or exchange of any Exchangeable Debenture so selected for redemption, in whole or in part, except the unredeemed portion of any Exchangeable Debenture being redeemed in part.

(b) The following provisions shall apply only to Global Debentures:

(i) Each Global Debenture authenticated under this Indenture shall be registered in the name of the Depositary or a nominee thereof and delivered to such Depositary or a nominee thereof or Custodian therefor, and each such Global Debenture shall constitute a single Exchangeable Debenture for all purposes of this Indenture.

(ii) Notwithstanding any other provision in this Indenture, no Global Debenture may be exchanged in whole or in part for Exchangeable Debentures registered, and no transfer of a Global Debenture in whole or in part may be registered, in the name of any Person other than the Depositary or a nominee thereof unless (1) the Depositary (x) has notified the Company that it is unwilling or unable to continue as Depositary for such Global Debenture or (y) has ceased to be a clearing agency registered under the Exchange Act, and a successor depositary has not been appointed by the Company within ninety (90) calendar days, (2) an Event of Default has occurred and is continuing or (3) the Company, in its sole discretion, notifies the Trustee in writing that it no longer wishes to have all the Exchangeable Debentures represented by Global Debentures. Any Global Debenture exchanged pursuant to clause (1) or (2) above shall be so exchanged in whole and not in part and any Global Debenture exchanged pursuant to clause (3) above may be exchanged in whole or from time to time in part as directed by the Company. Any Debenture issued in exchange for a Global Debenture or any portion thereof shall be a Global Debenture; provided that any such Exchangeable Debenture so issued that is registered in the name of a Person other than the Depositary or a nominee thereof shall not be a Global Debenture.

(iii) Exchangeable Debentures issued in exchange for a Global Debenture or any portion thereof pursuant to clause (ii) above shall be issued in definitive, fully registered form, without interest coupons, shall have an aggregate principal amount equal to that of such Global Debenture or portion thereof to be so exchanged, shall be registered in such names and be in such authorized denominations as the Depositary shall designate and shall bear any legends required hereunder. Any Global Debenture to be exchanged in whole shall be surrendered by the Depositary to the Trustee, as Exchangeable Debenture Registrar. With regard to any Global Debenture to be exchanged in part, either such Global Debenture shall be so surrendered for exchange or, if the Trustee is acting as Custodian for the Depositary or its nominee with respect to such Global Debenture, the principal amount thereof shall be reduced, by an amount equal to the portion thereof to be so exchanged, by means of an appropriate adjustment made on the records of the Trustee. Upon any such surrender or adjustment, the Trustee shall authenticate and make available for delivery the Exchangeable Debenture issuable on such exchange to or upon the written order of the Depositary or an authorized representative thereof.

(iv) In the event of the occurrence of any of the events specified in clause (ii) above, the Company will promptly make available to the Trustee a reasonable supply of certificated Exchangeable Debentures in definitive, fully registered form, without interest coupons.

(v) Neither any members of, or participants in, the Depositary (“Agent Members”) nor any other Persons on whose behalf Agent Members may act shall have any rights under this Twenty-Third Supplemental Indenture with respect to any Global Debenture registered in the name of the Depositary or any nominee thereof, and the Depositary or such nominee, as the case may be, may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and Holder of such Global Debenture for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or such nominee, as the case may be, or impair, as between the Depositary, its Agent Members and any other Person on whose behalf an Agent Member may act, the operation of customary practices of such Persons governing the exercise of the rights of a Holder of any Exchangeable Debenture.

(vi) At such time as all interests in a Global Debenture have been redeemed, repurchased, exchanged, or canceled for Exchangeable Debentures in certificated form, such Global Debenture shall, upon receipt thereof, be canceled by the Trustee in accordance with standing procedures and instructions existing between the Depositary and the Custodian. At any time prior to such cancellation, if any interest in a Global Debenture is redeemed, repurchased, exchanged, or canceled for Exchangeable Debentures in certificated form, the principal amount of such Global Debenture shall, in accordance with the standing procedures and instructions existing between the Depositary and the Custodian, be appropriately reduced, and an endorsement shall be made on such Global Debenture, by the Trustee or the Custodian, at the direction of the Trustee, to reflect such reduction.

(c) Every Exchangeable Debenture (and all securities issued in exchange therefor or in substitution thereof) that bears or is required under this Section 7.01(c) to bear the legend set forth in this Section 7.01(c) (the “Restricted Debentures Legend”), and any Host REIT Common Stock that bears or is required under this Section 7.01(c) to bear the Host REIT Common Stock legend set forth in this Section 7.01(c) (the “Common Stock Legend”) (collectively, the “Restricted Securities”) shall be subject to the restrictions on transfer set forth in this Section 2.05(c) (including those set forth in the legends below) unless such restrictions on transfer shall be waived by written consent of the Company, and the Holder of each such Restricted Security, by such Exchangeable Debenture Holder’s acceptance thereof, agrees to be bound by all such restrictions on transfer. As used in this Section 7.01(c), the term “transfer” means any sale, pledge, loan, transfer or other disposition whatsoever of any Restricted Security or any interest therein.

Until the Maturity Date for the Debentures any certificate evidencing a Restricted Security shall bear a legend in substantially the following form, or unless otherwise agreed by the Issuer in writing, with written notice thereof to the Trustee:

“THIS DEBENTURE (OR ITS PREDECESSOR) AND ANY COMMON STOCK ISSUABLE UPON THE EXCHANGE OF THIS DEBENTURE HAVE NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED, EXCEPT AS SET FORTH BELOW.

THE HOLDER OF THIS COMMON STOCK CERTIFICATE SHALL BE DEEMED BY THE ACCEPTANCE OF THIS COMMON STOCK CERTIFICATE TO HAVE AGREED TO ANY SUCH AMENDMENT OR SUPPLEMENT.”

Any such shares of Host REIT Common Stock as to which such restrictions on transfer shall have expired in accordance with their terms or as to which the conditions for removal of the Common Stock Legend set forth therein have been satisfied may, upon surrender of the certificates representing such shares of Host REIT Common Stock for exchange in accordance with the procedures of the transfer agent for the Host REIT Common Stock, be exchanged for a new certificate or certificates for a like number of shares of Host REIT Common Stock, which shall not bear the Common Stock Legend required by this Section 7.01(c).

(e) Any Restricted Securities purchased or owned by the Company or any Affiliate thereof may not be resold by the Company or such Affiliate unless registered under the Securities Act or resold pursuant to an exemption from the registration requirements of the Securities Act in a transaction which results in such Exchangeable Debentures or Host REIT Common Stock, as the case may be, no longer being “restricted securities” (as defined under Rule 144).

(f) Global Debenture Legend. To the extent required by the Depository, each Global Debenture shall bear a legend in substantially the following form:

“THIS GLOBAL SECURITY IS HELD BY THE DEPOSITORY (AS DEFINED IN THE INDENTURE GOVERNING THIS GLOBAL SECURITY) OR ITS NOMINEE IN CUSTODY FOR THE BENEFIT OF THE BENEFICIAL OWNERS HEREOF, AND IS NOT TRANSFERABLE TO ANY PERSON UNDER ANY CIRCUMSTANCES EXCEPT THAT (I) THE TRUSTEE MAY MAKE SUCH NOTATIONS HEREON AS MAY BE REQUIRED PURSUANT TO SECTION 7.01 OF THE TWENTY-THIRD SUPPLEMENTAL INDENTURE, (II) THIS GLOBAL SECURITY MAY BE EXCHANGED IN WHOLE BUT NOT IN PART PURSUANT TO SECTION 7.01(a) OF THE TWENTY-THIRD SUPPLEMENTAL INDENTURE, (III) THIS GLOBAL SECURITY MAY BE DELIVERED TO THE TRUSTEE FOR CANCELLATION PURSUANT TO SECTION 2.12 OF THE INDENTURE AND (IV) THIS GLOBAL SECURITY MAY BE TRANSFERRED TO A SUCCESSOR DEPOSITORY WITH THE PRIOR WRITTEN CONSENT OF THE COMPANY.”

All notices and communications to be given to the Holders and all payments to be made to Holders under the Exchangeable Debentures shall be given or made only to or upon the order of the registered Holders (which shall be the Depositary or its nominee in the case of a Global Debenture). The rights of beneficial owners in any Global Debenture shall be exercised only through the Depositary subject to the customary procedures of the Depository. The Trustee may rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its Agent Members.

The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Twenty-Third Supplemental Indenture or under applicable law with respect to any transfer of any interest in any Exchangeable Debenture

(including any transfers between or among Agent Members in any Global Indenture) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Twenty-Third Supplemental Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

(h) Cancellation and/or Adjustment of Global Debentures. At such time as all beneficial interests in a particular Global Debenture have been exchanged for Certificated Exchangeable Debentures or a particular Global Debenture has been redeemed, repurchased or cancelled in whole and not in part, each such Global Debenture shall be returned to or retained and cancelled by the Trustee in accordance with Section 2.12 of the Indenture.

[Reverse of Debenture]

2.625% EXCHANGEABLE SENIOR DEBENTURES DUE APRIL 15, 2027

Interest.

This Debenture shall bear interest at a rate of 2.625% per year on the principal hereof, from March 23, 2007 or from the most recent Interest Payment Date (as defined below) to which payment has been made or duly provided for, payable quarterly in arrears on January 15, April 15, July 15 and October 15 of each year, beginning July 15, 2007 (each an “Interest Payment Date”) to the persons in whose names the Debentures are registered at 5:00 p.m., New York City time, on December 31, March 31, June 30 and September 30 (each a “Regular Record Date”) (whether or not a Business Day), as the case may be, immediately preceding such Interest Payment Date. Each payment of interest shall include interest accrued for the period (the “Interest Period”), commencing on and including the immediately preceding Interest Payment Date (or, if none, March 23, 2007) to, but excluding the applicable Interest Payment Date. The amount of interest payable for any Interest Period shall be computed on the basis of a 360-day year consisting of twelve 30-day months. The amount of interest payable for any partial period shall be computed on the basis of a 360-day year of twelve 30-day months and the days elapsed in any partial month.

Holders of Debentures at 5:00 p.m., New York City time, on a Regular Record Date will receive payment of interest, including Liquidated Damages, if any, payable on the corresponding Interest Payment Date notwithstanding the exchange of such Debentures at any time after 5:00 p.m., New York City time, on such Regular Record Date. Debentures surrendered for exchange by a Holder during the period from 5:00 p.m., New York City time, on any Regular Record Date to 9:00 a.m., New York City time, on the immediately following Interest Payment Date must be accompanied by payment of an amount equal to the interest, including Liquidated Damages, if any, that the Holder is to receive on the Debentures; provided, however, that no such payment need be made (1) if the Company has specified a redemption date that is after a Regular Record Date and on or prior to the immediately following Interest Payment Date, (2) if the Company has specified a Designated Event Repurchase Date that is after such Regular Record Date and on or prior to such Interest Payment Date or (3) with respect to overdue interest, if any overdue interest exists at the time of exchange with respect to such Debentures.

The Company or Host REIT is permitted to deduct and withhold from payment of interest otherwise due to a Holder, from cash payable to a Holder on redemption or from shares of Host REIT common stock otherwise deliverable to a Holder upon exchange of a Debenture, and from any other payment made with respect to a Debenture, any amounts that either the Company or Host REIT is required by applicable laws to withhold and pay over to the applicable governmental authority, and any amount so deducted, withheld and paid over shall be deemed paid to such Holder.

2.	Method of Payment.

The Company shall pay interest on the Debentures (except defaulted interest) to the Persons who are the registered Holders at 5:00 p.m. on the Record Date immediately preceding the Interest Payment Date. Holders must surrender Debentures to a Paying Agent to collect principal payments. Principal of, and interest on the Debentures will be payable in United States Dollars at the office or agency of the Company maintained for such purpose, in the Borough of Manhattan, The City of New York or at the option of the Company, payment of interest may be made by check mailed to the Holders of the Debentures at the addresses set forth upon the registry books of the Company; provided, however, Holders of Global Debentures will be entitled to receive interest payments (other than at maturity) by wire transfer of immediately available funds, if appropriate wire transfer instructions have been received in writing by the Trustee not fewer than 15 days prior to the applicable Interest Payment Date. Such wire instructions, upon receipt by the Trustee, shall remain in effect until revoked by such Holder. No service charge will be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

3.	Paying Agent, Exchange Agent and Registrar.

Initially, the Trustee, shall act as Paying Agent, Exchange Agent and Registrar. The Company may appoint and change any Paying Agent, Exchange Agent, Registrar or co-registrar or approve a change in the office through which any Paying Agent acts without notice, other than notice to the Trustee. The Company or any of its Subsidiaries or any of their Affiliates may, subject to certain exceptions, act as Paying Agent, Exchange Agent, Registrar or co-registrar.

4.	Indenture.

The Company issued the Debentures and the Subsidiary Guarantors issued their Guarantees under an Amended and Restated Indenture, dated as of August 5, 1998, as supplemented (the “Indenture”), between the Company, its Parents, the Subsidiary Guarantors and the Trustee. Capitalized terms herein are used as defined in the Indenture unless otherwise defined herein. The Debentures are unlimited in aggregate principal amount. The terms of the Debentures include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as in effect on the date of the Indenture. The Debentures are subject to all such terms, and Holders of Debentures are referred to the Indenture and said Act for a statement of them. The Debentures are senior, general obligations of the Company, secured initially by a pledge of Capital Stock of certain Subsidiaries of the Company, which pledge is shared equally and ratably with the Credit Facility, the Existing Senior Notes and certain future Indebtedness of the Company ranking pari passu with the Debentures. Each Holder of this Debenture, by accepting the same, (a) agrees to and shall be bound by the provisions of the Indenture, (b) authorizes and directs the Trustee on his behalf to take such action as may be provided in the Indenture and (c) appoints the Trustee his attorney-in-fact for such purpose.

5.	Redemption at the Option of the Company.

The Company will not have the right to redeem any Debentures prior to April 20, 2012, except to preserve the status of Host REIT as a real estate investment trust. If, at any time, the Company determines it is necessary to redeem the Debentures in order to preserve the status of Host REIT as a real estate investment trust, the Company may redeem the Debentures, in whole or in part, for cash equal to 100% of the principal amount of the Debentures plus unpaid interest (including liquidated damages, if any) accrued to but excluding, the redemption date. In addition, on or after April 20, 2012, the Company will have the right to redeem the Debentures in whole or in part, at any time or from time to time, for cash equal to 100% of the principal amount of the Debentures to be redeemed plus unpaid interest, if any, accrued to, but excluding, the redemption date; provided, however, that if the redemption date falls after a record date and on or prior to the corresponding interest payment date, the Company will pay the full amount of accrued and unpaid interest, if any, on such interest payment date to the Holder of record at the close of business on the corresponding record date.

6.	Notice of Redemption.

Notice of redemption at the option of the Company shall be mailed at least 15 days but not more than 60 days before a redemption date to the each Holder of Debentures to be redeemed at the Holder’s registered address. Debentures in denominations larger than $1,000 principal amount may be redeemed in part but only in integral multiples of $1,000 principal amount.

7.	Purchase By the Company at the Option of the Holder.

(a) Subject to the terms and conditions of the Indenture, the Company shall become obligated to purchase, at the option of the Holder, all or any portion of the Debentures held by such Holder on April 15, 2012, April 15, 2017 and on April 15, 2022 (each a “Repurchase Date”), in integral multiples of $1,000 at a Repurchase Price equal to 100% of the principal amount of the Debentures to be repurchased.

(b) At the option of the Holder and subject to the terms and conditions of the Indenture, the Company shall become obligated to offer to purchase the Debentures held by such Holder upon a Designated Event. The Debentures shall be purchased at a repurchase price equal to 100% of the principal amount of the Debentures to be repurchased plus accrued and unpaid interest (including Liquidated Damages), if any, to, but not including, such Repurchase Date.

(c) Holders have the right to withdraw any written notice delivered pursuant to Paragraph 7(a) above or Designated Event Repurchase Notice delivered pursuant to Paragraph 7(b), as the case may be, by delivering to the Paying Agent a written notice of withdrawal in accordance with the provisions of the Indenture.

Exchange.

(a) The initial Exchange Rate is 31.0020 shares of Host REIT Common Stock per $1,000 principal amount at maturity,

subject to adjustment in certain events described in the Twenty-Third Supplemental Indenture. A Holder that surrenders Debentures for exchange will receive cash in lieu of any fractional share of Host REIT Common Stock based on the Average Price.

(b) Subject to and in compliance with the provisions of the Indenture (including, without limitation, the conditions to exchange of this Debenture set forth in Article 6 of the Twenty-Third Supplemental Indenture), under certain circumstances set forth on the Indenture, a Holder may exchange the Holder’s Debentures for, at the Company’s option, cash or cash and shares of Host REIT Common Stock with an aggregate value equal to the Exchange Value.

(c) A Debenture in respect of which a Holder has delivered a Repurchase Notice or Designated Event Repurchase Notice, as the case may be, exercising the right of such Holder to require the Company to repurchase such Debenture may be exchanged only if such Repurchase Notice or Designated Event Repurchase Notice is withdrawn in accordance with the terms of the Indenture.

(d) No payment or adjustment will be made for accrued and unpaid interest (including Liquidated Damages, if any) or dividends on the shares of Host REIT Common Stock, except as provided in the Indenture.

(e) To surrender a Debenture for exchange, in the case of a Global Debenture, a Holder must comply with all applicable procedures of the Depository, and in the case of a Certificated Security, a Holder must (1) complete and manually sign the irrevocable exchange notice below (or complete and manually sign a facsimile of such notice) and deliver such notice to the Exchange Agent, (2) surrender the Debenture, if certificated, to the Exchange Agent and in any such case furnish appropriate endorsements and transfer documents and pay any transfer or similar taxes and all other taxes or duties, if required.

(f) If the Company or Host REIT is a party to a consolidation, merger or a transfer of all or substantially all of its properties and assets as set forth in Article 5 of the Indenture, or a merger or binding share exchange which reclassifies or changes the outstanding shares of Host REIT Common Stock, the right to exchange a Debenture into shares of Host REIT Common Stock may be changed into a right to exchange it into securities, cash or other assets of the Company or another Person.

9.	Events of Default.

If an Event of Default with respect to the Debentures occurs and is continuing (other than an Event of Default relating to bankruptcy, insolvency or reorganization of the Company), then either the Trustee or the Holders of 25% in aggregate principal amount of the Debentures then outstanding may declare all Debentures to be due and payable immediately in the manner and with the effect provided in the Indenture. Holders of Debentures may not enforce the Indenture or the Debentures, except as provided in the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Debentures. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Debentures may direct the Trustee in its exercise of any trust or power with respect to such Debentures. The Trustee may withhold from Holders of Debentures notice of any continuing Default or Event of Default (except a Default in payment of principal or interest) if it determines that withholding notice is in their interest.

10.	Amendment; Supplement; Waiver.

The Company, the Subsidiary Guarantors and the Trustee may enter into a supplemental indenture for certain limited purposes without the consent of the Holders. Subject to certain exceptions, the Indenture or the Debentures may be amended or supplemented with the written consent of the Holders of not less than a majority in aggregate principal amount of the Debentures then outstanding (except that any amendments or supplements to the provisions relating to security interests or with respect to the Guarantees of the Subsidiary Guarantors shall require the consent of the holders of not less than 66 2/3% of the aggregate principal amount of the Debentures then outstanding), and any existing Default or Event of Default or compliance with any provision may be waived with the consent of the Holders of a majority in aggregate principal amount of the Debentures then outstanding.
