to $400,000,000 (the “Initial Original Principal Amount”). Notwithstanding the foregoing, the Company, without
notice to or the consent of the Holders of the Notes, by Board Resolutions or indentures supplemental to the Base Indenture from
time to time may increase the principal amount of the Notes by issuing Additional Notes in the future on the same terms and conditions
as the Initial Notes except for any difference in the issue price and interest accrued prior to the issue date of the Additional
Notes, and with the same CUSIP number as the Initial Notes so long as such Additional Notes are fungible for U.S. income tax purposes
with the Initial Notes (as determined by the Company). Except as provided in this Section 3.4, any such Board Resolutions
or indentures supplemental to the Base Indenture and Sections 2.1 and 3.1 of the Base Indenture, the Company shall not execute
and the Trustee shall not authenticate or deliver Notes in excess of the Initial Original Principal Amount.

Nothing contained in
this Section 3.4 or elsewhere in this Tenth Supplemental Indenture, or in the Notes, is intended to or shall limit execution
by the Company or authentication or delivery by the Trustee of the Notes under the circumstances contemplated in Sections 3.3,

Payment Date”), to the person in whose name such Note is registered at the close of business on the June 1 or December
1 (whether or not a Business Day), as the case may be, immediately preceding such Interest Payment Date (each, a “Record
Date”). Interest will be computed on the basis of a 360-day year composed of twelve 30-day months.


 


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 as if it were made on the date such payment was due and no interest shall accrue on the amount so payable for the
period from and after such Interest Payment Date, Maturity Date or Redemption Date, as the case may be.


 


The Notes will mature

may specify by written notice to the 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 June 15 or December 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:


 






    - 10 -


     


    

 


(a)           The
Company may elect to make payment of any Defaulted Interest to the persons in whose names the Notes are registered at 5:00 p.m.,
New York City time, on a special record date for the payment of such Defaulted Interest, which shall be fixed in the 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 Trustee
of such notice), and at the same time the Company shall deposit with the Trustee an amount of monies equal to the aggregate amount
to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit on or
prior to the date of the proposed payment, such monies when deposited to be held in trust for the benefit of the persons entitled
to such Defaulted Interest as in this clause provided. Thereupon the Company shall fix a special record date for the payment of
such 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 the proposed payment. The Company shall promptly notify the Trustee of such special record date and, in the name
and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the special record
date therefor to be 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.


 


(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 may
be required by such exchange or automated quotation system, if, after notice given by the Company to the Trustee of the proposed
payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.


 


Section 3.7.

(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.

Registered Securities; Global Form. The Notes will be issued in the form of one or more fully-registered Global Notes
in book-entry form, which will be deposited with, or on behalf of, the Depository. The Notes shall not be issuable in Definitive
Notes except as provided in Section 3.12 of this Tenth Supplemental Indenture. The Notes and the Trustee’s certificate
of authentication 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 Tenth Supplemental Indenture, expressly
agree to such terms and provisions and to be bound thereby.

Depository, by a nominee of the Depository to the Depository or to another nominee of the Depository, or by the Depository or
any such nominee to 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”), and, in either case, a successor Depository is not appointed by the Company within ninety (90) days after the
date of such notice from 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 or Sections 3.4 and 3.6 of the Base Indenture, shall be authenticated and delivered
in the form of, and shall be, a Global Note. A Global Note may not be exchanged for another Note other than as provided in this
Section 3.12(a), however, beneficial interests in a Global Note may be transferred and exchanged as provided in Section 3.12(c)
or (d) hereof.

All Other Transfers of Beneficial Interests in Global Notes. In connection with all transfers of beneficial interests
that are not subject to Section 3.12(c)(i) above, the transferor of such beneficial interest must deliver to the Security
Registrar both:


 


(A)            
a written order from a Participant or an Indirect Participant given to the Depository in accordance with the Applicable
Procedures directing the Depository to credit or cause to be credited a beneficial interest in another Global Note in an amount
equal to the beneficial interest to be transferred or exchanged; and


 


(B)

Transfer and Exchange of Beneficial Interests in Global Notes for Definitive Notes. If any holder of a beneficial

Global Note to be reduced accordingly pursuant to Section 3.12(g) hereof, and the Company will execute and the Trustee will

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)

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.

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

Article
IV



REDEMPTION


 


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


 


Section 4.1.         
Optional Redemption.


 


(a)          At
any time before September 15, 2029, 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 September 15, 2029 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.


 






    - 16 -


     


    

 


(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 thirty (30) 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.


 


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 thirty (30) calendar days prior to the Redemption Date.


 






    - 17 -


     


    

 



 


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 cease to be entitled to any benefit or security under this Indenture, and (d) the Holders of the Notes shall have no
right in respect of such Notes except the right to receive the Redemption Price thereof. On presentation and surrender of such
Notes at a place of payment in said notice specified, the said Notes or the specified portions thereof shall be paid and redeemed
by the Company at the Redemption Price.


 


Upon presentation of
any Note redeemed in part only, 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 Note or Notes, of authorized denominations, in principal amount equal
to the unredeemed portion of the Notes so presented.

(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 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

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 Tenth Supplemental Indenture shall be executed on behalf of the Guarantor by an Officer of the sole general partner of the
Guarantor.


 


(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 Tenth 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.

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

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.

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.


 


(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.


 






    - 22 -


     


    

 


(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 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 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.


 


(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.

Section 7.2.         
Acceleration of Maturity; Rescission and Annulment. If an Event of Default with respect to the Notes at the time

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


 


(b)              
the Holders of at least 25% in principal amount of the outstanding Notes shall have made written request to the Trustee

within 90 days after it occurs, unless such default shall have been cured or waived. Except in the case of a Default or Event of
Default in payment of principal of, premium, if any, or interest on the Notes, the Trustee may withhold the notice if and so long

a quorum for a meeting of Holders; provided, however, that if any action is to be taken at the meeting with
respect to a consent or waiver which may be given by the Holders of not less than a specified percentage in principal amount of
the outstanding Notes, the persons holding or representing the specified percentage in principal amount of the outstanding Notes
will constitute a quorum. In the absence of a quorum within thirty (30) minutes after the time appointed for any such meeting,
the meeting shall, if convened at the request of Holders, be dissolved. In any other case the meeting may be adjourned for a period
of not less than ten (10) days as determined by the chairman of the meeting prior to the adjournment of such meeting. In the absence
of a quorum at any such adjourned meeting, such adjourned meeting may be further adjourned for a period of not less than ten (10)

of any adjourned meeting shall be given as provided in Section 9.2 hereof, except that such notice need be given only once
not less than five (5) days prior to the date on which the meeting is scheduled to be reconvened. Notice of the reconvening of
an adjourned meeting shall state expressly the percentage, as provided above, of the principal amount of the outstanding Notes
which shall constitute a quorum.


 


Except as limited by
Section 9.2 of the Base Indenture, any resolution presented to a meeting or adjourned meeting duly reconvened at which a quorum

with respect to any request, demand, authorization, direction, notice, consent, waiver or other action which the Indenture expressly
provides may be made, given or taken by the Holders of a specified percentage, which is less than a majority, in principal amount
of the outstanding Notes may be adopted at a meeting or an adjourned meeting duly reconvened and at which a quorum is present as
aforesaid by the affirmative vote of the Holders of such specified percentage in principal amount of the outstanding Notes.


 


Any resolution passed
or decision taken at any meeting of Holders duly held in accordance with this Section 9.4 shall be binding on all the Holders,
whether or not such Holders were present or represented at the meeting.

Determination of Voting Rights; Conduct and Adjournment of Meetings.


 


(a)              
Notwithstanding any other provisions of the Indenture, the Trustee may make such reasonable regulations as it may deem advisable
for any meeting of Holders in regard to proof of the holding of Notes and of the appointment of proxies and in regard to the appointment
and duties of inspectors of votes, the submission and examination of proxies, certificates and other evidence of the right to vote,
and such other matters concerning the conduct of the meeting as it shall deem appropriate.


 


(b)              
The Trustee shall, by an instrument in writing, appoint a temporary chairman of the meeting, unless the meeting shall have
been called by the Company or by Holders as provided in Section 9.2(b) hereof, in which case the Company, the Guarantor or
the Holders calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman and
a permanent secretary of the meeting shall be elected by vote of the persons entitled to vote a majority in principal amount of
the outstanding Notes of such series represented at the meeting.


 


(c)              
At any meeting, each Holder or proxy shall be entitled to one (1) vote for each $1,000 principal amount of Notes held
or represented by him; provided, however, that no vote shall be cast or counted at any meeting in respect
of any Note challenged as not outstanding and ruled by the chairman of the meeting to be not outstanding. The chairman of the meeting
shall have no right to vote, except as a Holder or proxy.


 


(d)              
Any meeting of Holders duly called pursuant to Section 9.2 hereof at which a quorum is present may be adjourned from
time to time by persons entitled to vote a majority in principal amount of the outstanding Notes represented at the meeting; and
the meeting may be held as so adjourned without further notice.


 


Section 9.6.         
Counting Votes and Recording Action of Meetings. The vote upon any resolution submitted to any meeting of Holders
shall be by written ballots on which shall be subscribed the signatures of the Holders or of their representatives by proxy and
the principal amounts and serial numbers of the outstanding Notes held or represented by them. The permanent chairman of the meeting
shall appoint two (2) inspectors of votes who shall count all votes cast at the meeting for or against any resolution and
who shall make and file with the secretary of the meeting their verified written reports in triplicate of all votes cast at the
meeting. A record, at least in triplicate, of the proceedings of each meeting of Holders shall be prepared by the secretary of
the meeting and there shall be attached to said record the original reports of the inspectors of votes on any vote by ballot taken
thereat and affidavits by one or more persons having knowledge of the facts setting forth a copy of the notice of the meeting and
showing that said notice was given as provided in Section 9.2 hereof and, if applicable, Section 9.4 hereof. Each copy
shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one (1) such copy
shall be delivered to the Company and the Guarantor, and another to the Trustee to be preserved by the Trustee, the latter to have
attached thereto the ballots voted at the meeting. Any record so signed and verified shall be conclusive evidence of the matters
therein stated.

and is continuing, the principal of, premium, if any, and accrued and unpaid interest on all Notes may be declared to be due and

upon said declaration the same shall be immediately due and payable. If an Event of Default specified in Sections 7.1(f),

of the Indenture, the Holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding may,
on behalf of the Holders of all of the Notes, waive any past Default or Event of Default, subject to exceptions set forth in the
Indenture.


 


No reference herein
to the Indenture and no provision of this Note or of the Indenture shall impair, as among the Company and the Holder of the Notes,
the obligation of the Company, which is absolute and unconditional, to pay the principal of, premium, if any, on and interest on
this Note at the place, at the respective times, at the rate and in the coin or currency prescribed herein and in the Indenture.


 


Interest on the Notes
shall be computed on the basis of a 360-day year of twelve 30-day months.

for a like aggregate principal amount of Notes of any other authorized denominations.


 


The Company shall have
the right to redeem the Notes under certain circumstances as set forth in Article IV of the Tenth Supplemental Indenture.

represented thereby, shall be had against any incorporator, stockholder, limited partner, member, manager, employee, agent, officer,
director or subsidiary, as such, past, present or future, of the Guarantor, the Company or any of the Company’s Subsidiaries
or of any successor thereto, either directly or through the Guarantor, the Company or any of the Company’s Subsidiaries or
