designates. If the format or content of the Statistical Release changes in a manner that precludes determination of the Treasury yield
in the above manner, then the Treasury yield shall be determined in the manner that most closely approximates the above manner, as reasonably
determined by the Company.

If any Interest Payment Date,
Maturity Date or Redemption Date falls on a day that is not a Business Day, the required payment shall be made on the next Business Day

Company that it pay interest by wire transfer of immediately available funds to the account specified by the Holder in such notice, or
(ii) on any Global Note by wire transfer of immediately available funds to the account of the Depository or its nominee. Any interest
on any Note which is payable, but is not punctually paid or duly provided for, on any March 15 or September 15 (herein called “Defaulted
Interest”) shall forthwith cease to be payable to the Holder registered as such on the relevant Record Date, and such Defaulted
Interest shall be paid by the Company, at its election in each case, as provided in clause (a) or (b) below:


 


(a)               The
Company may elect to make payment of any Defaulted Interest to the persons in whose names the Notes are registered at

following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each
Note and the date of the proposed payment (which shall be not less than twenty-five (25) calendar days after the receipt by the

Defaulted Interest which shall be not more than fifteen (15) calendar days and not less than ten (10) calendar days prior
to the date of the proposed payment, and not less than ten (10) calendar days after the receipt by the Trustee of the notice of

delivered to each Holder at its address as it appears in the register, not less than ten (10) calendar days prior to such
special record date. Notice of the proposed payment of such Defaulted Interest and the special record date therefor having been so
mailed, such Defaulted Interest shall be paid to the persons in whose names the Notes are registered at 5:00 p.m., New York
City time, on such special record date and shall no longer be payable pursuant to the following clause (b) of this
Section 3.6.


 






    - 11 -


     


    

 


(b)              
The Company may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any
securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, and upon such notice as

(past or present) of the Company or the Guarantor, as such, will have any liability for any of the Company’s or the Guarantor’s
obligations under the Notes, the Guarantee or the Indenture or for any claim based on, in respect of, or by reason of, such obligations
or their creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of
the consideration for issuance of the Notes.


 


Section 3.11.

shall be substantially in the form attached as Exhibit A hereto. The Company shall execute each Global Note and each Definitive Note,
if any. The Trustee shall, in accordance with Section 3.3 of the Base Indenture, authenticate and hold each Global Note as custodian
for the Depository, and authenticate each Definitive Note, if any. Each Global Note will represent such of the outstanding Notes as will
be specified therein and each shall provide that it represents the aggregate principal amount of outstanding Notes from time to time endorsed
thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be reduced or increased,
as appropriate, to reflect exchanges and redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease
in the aggregate principal amount of outstanding Notes represented thereby will be made by the Trustee or a custodian at the direction
of the Trustee. The terms and provisions contained in the form of Note attached as Exhibit A hereto shall constitute, and are hereby
expressly made, a part of the Indenture and, to the extent applicable, the Company and the Trustee, by their execution and delivery of
this Sixteenth Supplemental Indenture, expressly agree to such terms and provisions and to be bound thereby.

a successor Depository or a nominee of such successor Depository. All Global Notes will be exchanged by the Company for Definitive Notes
if:


 


(i)                
the Company delivers to the Trustee notice from the Depository that it is unwilling or unable to continue to act as Depository
or that it is no longer a clearing agency registered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”),

the Depository; or


 


(ii)             
the Company in its sole discretion determines that the Global Notes (in whole but not in part) should be exchanged for Definitive
Notes and delivers a written notice to such effect to the Trustee.


 


Upon the occurrence of either
of the preceding events in (i) or (ii) above, Definitive Notes shall be issued in such names as the Depository shall instruct the Trustee.
Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 3.4 and 3.6 of the Base Indenture. Every
Note authenticated and delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 3.12

in a Global Note may be transferred and exchanged as provided in Section 3.12(c) or (d) hereof.

UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE
OR IN PART FOR NOTES IN DEFINITIVE FORM, THIS NOTE MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY THE DEPOSITORY TO A NOMINEE OF THE DEPOSITORY
OR BY A NOMINEE OF THE DEPOSITORY TO THE DEPOSITORY OR ANOTHER NOMINEE OF THE DEPOSITORY OR BY THE DEPOSITORY OR ANY SUCH NOMINEE TO A

AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL
INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.”

(ii)             
All Other Transfers of Beneficial Interests in Global Notes. In connection with all transfers of beneficial interests that

the requirements for transfer or exchange of beneficial interests in Global Notes contained in the Indenture and the Notes or otherwise
applicable under the Securities Act, the Trustee shall adjust the principal amount of the relevant Global Note(s) pursuant to Section 3.12(g)
hereof.


 


(d)              
Transfer and Exchange of Beneficial Interests in Global Notes for Definitive Notes. If any holder of a beneficial interest
in a Global Note proposes to exchange such beneficial interest for a Definitive Note or to transfer such beneficial interest to a person
who takes delivery thereof in the form of a Definitive Note, then, upon satisfaction of the conditions set forth in Section 3.12(c)(ii)
hereof and receipt of a Company Order, the Trustee will cause the aggregate principal amount of the applicable Global Note to be reduced
accordingly pursuant to Section 3.12(g) hereof, and the Company will execute and the Trustee will authenticate and deliver to the
person designated in the instructions a Definitive Note in the appropriate principal amount. Any Definitive Note issued in exchange for
a beneficial interest pursuant to this Section 3.12(d) will be registered in such name or names and in such authorized denomination
or denominations as the holder of such beneficial interest requests through instructions to the Security Registrar from or through the
Depository and the Participant or Indirect Participant. The Trustee will deliver such Definitive Notes to the persons in whose names such
Notes are so registered.


 


(e)              
Transfer and Exchange of Definitive Notes for Beneficial Interests in Global Notes. A Holder of a Definitive Note may exchange
such Note for a beneficial interest in a Global Note or transfer such Definitive Notes to a person who takes delivery thereof in the form
of a beneficial interest in a Global Note at any time. Upon receipt of a written request for such an exchange or transfer, the Trustee
will cancel the applicable Definitive Note and increase or cause to be increased the aggregate principal amount of one of the Global Notes.


 


If any such exchange or transfer
from a Definitive Note to a beneficial interest is effected pursuant to the previous paragraph at a time when a Global Note has not yet
been issued, the Company will issue and, upon receipt of a Company Order in accordance with Section 3.12 hereof, the Trustee will
authenticate one or more Global Notes in an aggregate principal amount equal to the principal amount of Definitive Notes so transferred.

Transfer and Exchange of Definitive Notes for Definitive Notes. Upon request by a Holder of Definitive Notes and such Holder’s
compliance with the provisions of this Section 3.12(f), the Security Registrar will register the transfer or exchange of Definitive
Notes. Prior to such registration of transfer or exchange, the requesting Holder will present or surrender to the Security Registrar the
Definitive Notes duly endorsed or accompanied by a written instruction of transfer in form satisfactory to the Security Registrar duly
executed by such Holder or by his attorney, duly authorized in writing. A Holder of Definitive Notes may transfer such Notes to a person
who takes delivery thereof in the form of a Definitive Note. Upon receipt of a written request to register such a transfer, the Security
Registrar shall register the Definitive Notes pursuant to the instructions from the Holder thereof.

Definitive Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such Global
Note will be returned to or retained and canceled by the Trustee in accordance with Section 3.9 of the Base Indenture. At any

other Global Note will be increased accordingly and an endorsement will be made on such Global Note by the Trustee or by the
Depository at the direction of the Trustee to reflect such increase.

Article
IV



REDEMPTION


 


The provisions of Article XI
of the Base Indenture, as amended by the provisions of this Sixteenth Supplemental Indenture, shall apply to the Notes.


 


Section 4.1.         
Optional Redemption.


 


(a)              
At any time before March 15, 2034, the Company shall have the right to redeem the Notes at its option and in its sole discretion,
in whole or from time to time in part. The redemption price (“Redemption Price”) shall be equal to the sum of (1) the
principal amount of the Notes being redeemed, (2) accrued and unpaid interest thereon to, but excluding, the Redemption Date, and
(3) the Make-Whole Amount, if any (subject to the right of holders of record on the relevant Record Date to receive interest due
on the relevant Interest Payment Date). Notwithstanding the foregoing, the Redemption Price for any redemption of the Notes on or after
December 15, 2033 shall be equal to the sum of (1) the principal amount of the Notes being redeemed and (2) accrued and unpaid
interest thereon to, but excluding, the Redemption Date.


 


(b)              
The Company shall not redeem the Notes pursuant to Section 4.1(a) hereof on any date if the principal amount of the Notes
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 Notes to be redeemed).


 


Section 4.2.          Notice
of Optional Redemption; Selection of Notes. In case the Company shall desire to exercise the right to redeem all or, as the case
may be, any part of the Notes pursuant to Section 4.1 hereof, it shall fix a date for redemption and it or, at its written
request received by the Trustee not fewer than five (5) Business Days prior (or such shorter period of time as may be acceptable to
the Trustee) to the date the notice of redemption is to be delivered, the Trustee in the name of and at the expense of the Company,
shall deliver or cause to be delivered a notice of such redemption not fewer than ten (10) calendar days nor more than sixty
(60) calendar days prior to the Redemption Date to each Holder of Notes so to be redeemed in whole or in part at its last
address as the same appears on the register; provided that if the Company makes such request of the Trustee, it shall,
together with such request, also give written notice of the Redemption Date to the Trustee; provided further that the text of
the notice shall be prepared by the Company. The notice, if delivered in the manner herein provided, shall be conclusively presumed
to have been duly given, whether or not the Holder receives such notice. In any case, failure to give such notice or any defect in
the notice to the Holder of any Note designated for redemption as a whole or in part shall not affect the validity of the
proceedings for the redemption of any other Note. Any such notice of redemption may, in the Company’s sole discretion, be
conditioned on the occurrence of one or more events, facts and circumstances.


 






    - 17 -


     


    

 


Each such notice of redemption
shall specify: (i) the aggregate principal amount of Notes to be redeemed, (ii) the CUSIP number or numbers, if any, of the
Notes being redeemed, (iii) the Redemption Date (which shall be a Business Day), (iv) the Redemption Price at which Notes are
to be redeemed, (v) the place or places of payment and that payment will be made upon presentation and surrender of such Notes and
(vi) that interest accrued and unpaid to, but excluding, the Redemption Date will be paid as specified in said notice, and that,
unless the Company defaults in the payment of the Redemption Price, on and after said date interest thereon or on the portion thereof
to be redeemed will cease to accrue. If fewer than all the Notes are to be redeemed, the notice of redemption shall identify the Notes
to be redeemed (including CUSIP numbers, if any). In case any Note is to be redeemed in part only, the notice of redemption shall state
the portion of the principal amount thereof to be redeemed and shall state that, on and after the Redemption Date, upon surrender of such
Note, a new Note or Notes in principal amount equal to the unredeemed portion thereof will be issued.


 


Whenever any Notes are to
be redeemed, the Company will give the Trustee written notice of the Redemption Date as to the aggregate principal amount of Notes to
be redeemed not fewer than ten (10) calendar days prior to the Redemption Date.


 


On or prior to the Redemption
Date specified in the notice of redemption given as provided in this Section 4.2, the Company will deposit with the Paying Agent
an amount of monies in immediately available funds sufficient to redeem on the Redemption Date all the Notes (or portions thereof) so
called for redemption at the appropriate Redemption Price; provided that if such payment is made on the Redemption Date, it must
be received by the Paying Agent, by 11:00 a.m., New York City time, on such date.


 


If less than all of the outstanding
Notes are to be redeemed, the Trustee shall select the Notes or portions thereof of the Global Note or the Notes in certificated form
to be redeemed (in principal amounts of $2,000 and integral multiples of $1,000 in excess thereof), on a pro rata basis or such other
method the Trustee deems fair and appropriate or is required by the Depository. The Notes (or portions thereof) so selected for redemption
shall be deemed duly selected for redemption for all purposes hereof.


 


Section 4.3.          Payment
of Notes Called for Redemption by the Company. If notice of redemption has been given as provided in Section 4.2 hereof,
the Notes or portion of Notes with respect to which such notice has been given shall become due and payable on the Redemption Date
and at the place or places stated in such notice at the Redemption Price, and unless the Company shall default in the payment of
such Notes at the Redemption Price, so long as the Paying Agent holds funds sufficient to pay the Redemption Price of the Notes to
be redeemed on the Redemption Date, then (a) such Notes will cease to be outstanding on and after the Redemption Date,
(b) interest on the Notes or portion of Notes so called for redemption shall cease to accrue on and after the Redemption Date,
(c) on and after the Redemption Date (unless the Company shall default in the payment of the Redemption Price), such Notes will

V



GUARANTEE


 


This Article V shall replace
Article XIV of the Base Indenture with respect to the Notes only.


 


Section 5.1.         
Guarantee. By its execution hereof, the Guarantor acknowledges and agrees that the Notes shall be entitled to the benefits
of a Guarantee. Accordingly, subject to the provisions of this Article V, the Guarantor hereby unconditionally guarantees to each Holder
of a Note authenticated and delivered by the Trustee or its successor or assign, and to the Trustee and its successors and assigns that:
(i) the principal of (including the Redemption Price upon redemption pursuant to Article IV hereof), premium, if any, and interest,
if any, on the Notes shall be duly and punctually paid in full when due, whether at the Maturity Date, upon acceleration, upon redemption
or otherwise, and interest on overdue principal, premium, if any, and (to the extent permitted by law) interest on any interest, if any,
on the Notes and all other obligations of the Company to the Holders or the Trustee hereunder or under the Notes (including fees, expenses
or other) shall be promptly paid in full or performed, all in accordance with the terms hereof; and (ii) in case of any extension
of time of payment or renewal of any Notes or any of such other obligations, the same shall be promptly paid in full when due or performed
in accordance with the terms of the extension or renewal, whether at the Maturity Date, by acceleration, call for redemption or otherwise,
subject, however, in the case of clauses (i) and (ii) above, to the limitations set forth in this Article V (collectively, the “Guarantee
Obligations”).


 


Subject to the
provisions of this Article V, the Guarantor hereby agrees that its Guarantee hereunder shall be unconditional, irrespective of the
validity, regularity or enforceability of the Notes or the Indenture, the absence of any action to enforce the same, any waiver or
consent by any Holder of the Notes with respect to any thereof, the entry of any judgment against the Company, any action to enforce
the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of the Guarantor. The
Guarantor hereby waives and relinquishes: (a) any right to require the Trustee, the Holders or the Company (each, a
 “Benefited Party”) to proceed against the Company or any other person or to proceed against or exhaust any
security held by a Benefited Party at any time or to pursue any other remedy in any secured party’s power before proceeding
against the Guarantor; (b) any defense that may arise by reason of the incapacity, lack of authority, death or disability of
any other person or persons or the failure of a Benefited Party to file or enforce a claim against the estate (in administration,
bankruptcy or any other proceeding) of any other person or persons; (c) demand, protest and notice of any kind (except as
expressly required by the Indenture), including but not limited to notice of the existence, creation or incurring of any new or
additional indebtedness or obligation or of any action or non-action on the part of the Guarantor, any Benefited Party, any
creditor of the Guarantor or the Company or on the part of any other person whomsoever in connection with any obligations the
performance of which are hereby guaranteed; (d) any defense based upon an election of remedies by a Benefited Party, including
but not limited to an election to proceed against the Guarantor for reimbursement; (e) any defense based upon any statute or
rule of law which provides that the obligation of a surety must be neither larger in amount nor in other respects more burdensome
than that of the principal; (f) any defense arising because of a Benefited Party’s election, in any proceeding instituted
under the Bankruptcy Law, of the application of Section 1111(b)(2) of the Bankruptcy Law; and (g) any defense based on any
borrowing or grant of a security interest under Section 364 of the Bankruptcy Law. The Guarantor hereby covenants that, except
as otherwise provided therein, the Guarantee shall not be discharged except by payment in full of all Guarantee Obligations,
including, but not limited to, the principal, premium, if any, and interest on the Notes and all other costs provided for under the
Indenture.

If any Holder or the Trustee
is required by any court or otherwise to return to either the Company or the Guarantor, or any trustee or similar official acting in relation
to either the Company or the Guarantor, any amount paid by the Company or the Guarantor to the Trustee or such Holder, the Guarantee,
to the extent theretofore discharged, shall be reinstated in full force and effect. The Guarantor agrees that it shall not be entitled
to any right of subrogation in relation to the Holders in respect of any Guarantee Obligations hereby until payment in full of all such
obligations guaranteed hereby. The Guarantor agrees that, as between it, on the one hand, and the Holders of Notes and the Trustee, on
the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article V of the Base
Indenture for the purposes hereof, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of
the Guarantee Obligations, and (y) in the event of any acceleration of such obligations as provided in Article V of the Base
Indenture, such Guarantee Obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantor for the
purpose of the Guarantee.


 


Section 5.2.         
Execution and Delivery of Guarantee.


 


(a)              
To evidence the Guarantee set forth in Section 5.1 hereof, the Guarantor agrees that a Notation of Guarantee substantially
in the form included in Exhibit B hereto shall be endorsed on each Note authenticated and delivered by the Trustee and that this
Sixteenth Supplemental Indenture shall be executed on behalf of the Guarantor by an Officer of the sole general partner of the Guarantor.


 






    - 20 -


     


    

 





(b)              
 The Guarantor agrees that the Guarantee set forth in this Article V shall remain in full force and effect and apply to all the
Notes notwithstanding any failure to endorse on each Note a notation of the Guarantee.


 


(c)              
If an Officer whose facsimile signature is on a Note or a notation of Guarantee no longer holds that office at the time the Trustee
authenticates the Note on which the Guarantee is endorsed, the Guarantee shall be valid nevertheless.


 


(d)              
The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Guarantee
set forth in this Sixteenth Supplemental Indenture on behalf of the Guarantor.


 


Section 5.3.         
Limitation of Guarantor’s Liability; Certain Bankruptcy Events.


 


(a)              
The Guarantor, and by its acceptance hereof each Holder, hereby confirms that it is the intention of all such parties that the
Guarantee Obligations of the Guarantor pursuant to its Guarantee not constitute a fraudulent transfer or conveyance for purposes of any
Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law. To effectuate
the foregoing intention, the Holders and the Guarantor hereby irrevocably agree that the Guarantee Obligations of the Guarantor under
this Article V shall be limited to the maximum amount as shall, after giving effect to all other contingent and fixed liabilities of the
Guarantor, result in the Guarantee Obligations of the Guarantor under the Guarantee not constituting a fraudulent transfer or conveyance.


 


(b)              
The Guarantor hereby covenants and agrees, to the fullest extent that it may do so under applicable law, that in the event of the
insolvency, bankruptcy, dissolution, liquidation or reorganization of the Company, the Guarantor shall not file (or join in any filing
of), or otherwise seek to participate in the filing of, any motion or request seeking to stay or to prohibit (even temporarily) execution
on the Guarantee and hereby waives and agrees not to take the benefit of any such stay of execution, whether under Section 362 or
105 of the Bankruptcy Law or otherwise.


 


Section 5.4.         
Application of Certain Terms and Provisions to the Guarantor.


 


(a)              
For purposes of any provision of the Indenture which provides for the delivery by the Guarantor of an Officers’ Certificate
and/or an Opinion of Counsel, the definitions of such terms in Section 2.1 hereof shall apply to the Guarantor as if references therein
to the Company or the Guarantor, as applicable, were references to the Guarantor; provided that, in the case of any Officers’ Certificate
delivered by the Guarantor, the definition of the term “Officer” shall be deemed to include the general partner of the Guarantor.


 


(b)              
Upon any demand, request or application by the Guarantor to the Trustee to take any action under the Indenture, the Guarantor shall
furnish to the Trustee such certificates and opinions as are required in Section 1.2 of the Base Indenture, as if all references
therein to the Company were references to the Guarantor.

Article
VI




ADDITIONAL COVENANTS


 


The following additional covenants
shall apply with respect to the Notes so long as any of the Notes remain outstanding.


 


Section 6.1.         
Maintenance of Office or Agency. The Company will maintain an office or agency in the United States where the Notes may
be surrendered for registration of transfer or exchange or for presentation for payment or redemption and where notices and demands to
or upon the Company in respect of the Notes and the Indenture may be served. As of the date of the Indenture, such office shall be the
Corporate Trust Office and, at any other time, at such other address as the Trustee may designate from time to time by notice to the Company.
The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency not
designated or appointed by the Trustee. If at any time the Company shall fail to maintain any such required office or agency or shall
fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office; provided that the Corporate Trust Office shall not be an office for service of legal process on the Company or
any Guarantor.


 


The Company may also from
time to time designate co-registrars and one or more offices or agencies where the Notes may be presented or surrendered for any or
all such purposes and may from time to time rescind such designations. The Company will give prompt written notice to the Trustee of any
such designation or rescission and of any change in the location of any such other office or agency.


 


The Company hereby initially
designates the Trustee as Paying Agent and Security Registrar and the Corporate Trust Office shall be considered as one such office or
agency of the Company for each of the aforesaid purposes.


 


Section 6.2.         
Appointments to Fill Vacancies in Trustee’s Office. The Company, whenever necessary to avoid or fill a vacancy in
the office of Trustee, will appoint, upon the terms and conditions and otherwise as provided in Section 6.11 of the Base Indenture,
a Trustee, so that there shall at all times be a Trustee hereunder.


 


Section 6.3.         
Limitations on Incurrence of Debt.


 


(a)               The
Company will not, and will not permit any of its Subsidiaries to, incur any Debt, other than Intercompany Debt and guarantees of
Debt incurred by the Company or its Subsidiaries in compliance with this Indenture, if, immediately after giving effect to the
incurrence of such Debt and the application of the proceeds thereof, the aggregate principal amount of all of the Company’s
and its Subsidiaries’ outstanding Debt on a consolidated basis determined in accordance with GAAP is greater than 60% of the
sum of (without duplication) (1) Total Assets as of the end of the calendar quarter covered in the Company’s Annual
Report on Form 10-K or Quarterly Report on Form 10-Q, as the case may be, most recently filed with the Commission
(or, if such filing is not permitted under the Exchange Act, with the Trustee) prior to the incurrence of such additional Debt and
(2) the purchase price of any real estate assets or mortgages receivable acquired, and the amount of any securities offering
proceeds received (to the extent such proceeds were not used to acquire real estate assets or mortgages receivable or used to reduce
Debt), by the Company or any of its Subsidiaries since the end of such calendar quarter, including those proceeds obtained in
connection with the incurrence of such additional Debt.


 






    - 22 -


     


    

 


(b)              
The Company will not, and will not permit any of its Subsidiaries to, incur any Debt, other than Intercompany Debt and guarantees
of Debt incurred by the Company or its Subsidiaries in compliance with this Indenture, secured by any mortgage, lien, charge, pledge,
encumbrance or security interest of any kind upon any of the Company’s or any of its Subsidiaries’ property if, immediately
after giving effect to the incurrence of such Debt and the application of the proceeds thereof, the aggregate principal amount of all
of the Company’s and its Subsidiaries’ outstanding Debt on a consolidated basis which is secured by any mortgage, lien, charge,
pledge, encumbrance or security interest on the Company’s or its Subsidiaries’ property is greater than 40% of the sum of
(without duplication) (1) Total Assets as of the end of the calendar quarter covered in the Company’s Annual Report on Form 10-K
or Quarterly Report on Form 10-Q, as the case may be, most recently filed with the Commission (or, if such filing is not permitted
under the Exchange Act, with the Trustee) prior to the incurrence of such additional Debt and (2) the purchase price of any real
estate assets or mortgages receivable acquired, and the amount of any securities offering proceeds received (to the extent such proceeds
were not used to acquire real estate assets or mortgages receivable or used to reduce Debt), by the Company or any of its Subsidiaries
since the end of such calendar quarter, including those proceeds obtained in connection with the incurrence of such additional Debt; provided
that for purposes of this limitation, the amount of obligations under capital leases shown as a liability on the Company’s consolidated
balance sheet shall be deducted from Debt and from Total Assets.


 


(c)               The
Company will not, and will not permit any of its Subsidiaries to, incur any Debt, other than Intercompany Debt and guarantees of
Debt by the Company or its Subsidiaries in compliance with this Indenture, if the ratio of Consolidated EBITDA to Interest Expense
for the four consecutive fiscal quarters most recently ended prior to the date on which such additional Debt is to be incurred shall
have been less than 1.5 to 1.0, on an unaudited pro forma basis after giving effect to the incurrence of such additional Debt and to
the application of the proceeds therefrom, and calculated on the assumption that: (1) such Debt and any other Debt incurred by
the Company and its Subsidiaries since the first day of such four-quarter period and the application of the proceeds therefrom,
including to refinance other Debt, had occurred at the beginning of such period (except that, in making such computation, the amount
of Debt under any revolving credit facility and commercial paper program shall be computed based on the average daily balance of
such Debt during such period); (2) the repayment or retirement of any other Debt by the Company and its Subsidiaries since the
first day of such four-quarter period had been repaid or retired at the beginning of such period (except that, in making such
computation, the amount of Debt under any revolving credit facility and commercial paper program shall be computed based upon the
average daily balance of such Debt during such period); (3) in the case of Acquired Debt or Debt incurred in connection with
any acquisition since the first day of such four-quarter period, the related acquisition had occurred as of the first day of such
period, with the appropriate adjustments with respect to such acquisition being included in such unaudited pro forma calculation;
and (4) in the case of any acquisition or disposition by the Company or its Subsidiaries of any asset or group of assets or
other placement of any assets in service or removal of any assets from service by the Company or any of its Subsidiaries since the
first day of such four-quarter period, whether by merger, stock purchase or sale, or asset purchase or sale, such acquisition,
disposition, placement in service or removal from service, or any related repayment of Debt had occurred as of the first day of such
period, with the appropriate adjustments with respect to such acquisition, disposition, placement in service or removal from
service, being included in such unaudited pro forma calculation and determined reasonably and in good faith by the Company. If the
Debt giving rise to the need to make the foregoing calculation or any other Debt incurred after the first day of the relevant
four-quarter period bears interest at a floating rate then, for purposes of calculating the Interest Expense, the interest rate on
such Debt shall be computed on a pro forma basis as if the average interest rate which would have been in effect during the entire
such four-quarter period had been the applicable rate for the entire such period.


 






    - 23 -


     


    

 


(d)              
The Company, together with its Subsidiaries, will at all times maintain an Unencumbered Total Asset Value in an amount not less
than 150% of the aggregate outstanding principal amount of all the Company’s and its Subsidiaries’ unsecured Debt, taken as
a whole.


 


(e)              
The Company will, and will cause each of its Subsidiaries to, maintain insurance with financially sound and reputable insurance
companies against such risks and in such amounts as is customarily maintained by persons engaged in similar businesses or as may be required
by applicable law.


 


Section 6.4.         
Provision of Financial Reporting Information. For so long as the Notes are outstanding, if at any time the Company is not
subject to the periodic reporting requirements of the Exchange Act for any reason, the Company shall, at its option, (i) post on a publicly
available website, (ii) post on IntraLinks or any comparable password protected online data system requiring user identification and a
confidentiality acknowledgement (any such data system, a “Confidential Datasite”), or (iii) deliver to the Trustee
and the Holders of the Notes, in each case within 15 days of the filing date that would be applicable to a non-accelerated filer at that
time pursuant to applicable SEC rules and regulations, the quarterly and audited annual financial statements and accompanying “Management’s
Discussion and Analysis of Financial Condition and Results of Operations” that would have been required to be contained in annual
reports on Form 10-K and quarterly reports on Form 10-Q, respectively, had the Company been subject to such Exchange Act reporting requirements.
The Trustee shall have no obligation to determine whether or not such reports, information, statements or documents have been filed, posted
or delivered. Delivery of such reports, information, statements and documents to the Trustee is for informational purposes only, and the
Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information
contained therein, including the Company’s compliance with any of its covenants under the Indenture. If the Company elects to furnish
such reports via a Confidential Datasite, access to the Confidential Datasite will be provided upon request to the Holders and the beneficial
owners of and bona fide potential investors in the Notes.

such Holder has previously given to the Trustee written notice of a continuing Event of Default with respect to the Notes;


 


(b)

at the respective times, at the rate and in the coin or currency prescribed herein and in the Indenture.
