the Operating Partnership or such Subsidiary, as the case may be, will be deemed to have incurred, at such time, an amount of Debt equal to the outstanding amount of such Debt at such time. The reference to “Notes” in clause (3) of

time to time, may be designated to be the Principal Credit Agreement so long as neither such agreement nor any guarantees or other instruments or agreements, if any, executed in connection therewith includes any covenant or agreement that requires

June 1 or December 1 (each such date being a Regular Record Date for the Notes), as the case may be, immediately preceding such Interest Payment Dates, regardless of whether or not any such Regular Record Date is a Business Day.

ADDITIONAL COVENANTS FOR THE BENEFIT OF HOLDERS OF NOTES

Article Ten of the Original Indenture is hereby supplemented, but solely insofar as relates to the Notes, by adding the following new sections
to appear immediately after Section 1010 of 

  
 12 








 
the Original Indenture and to read in full as follows (and the Table of Contents in the Original Indenture is amended, but solely insofar as relates to the Notes, to insert the section numbers
and titles of the following sections in appropriate sequence): 
  

	 	“Section 1011.	Limitation on Incurrence of Total Debt. 

 “The Operating Partnership will not, and
will not cause or permit any of its Subsidiaries to, incur any Debt if, immediately after giving effect to the incurrence of such additional Debt and the application of the proceeds thereof on a pro forma basis, the aggregate principal amount
of all outstanding Debt of the Operating Partnership and its Subsidiaries on a consolidated basis determined in accordance with GAAP is greater than 60% of the sum of (without duplication): 

 

	 	“(1)	Adjusted Total Assets as of the end of the most recent fiscal quarter prior to the incurrence of such additional Debt; 

  

	 	“(2)	the aggregate purchase price of any real estate assets or mortgages receivable (or interests therein) acquired by the Operating Partnership or any of its Subsidiaries since the end of such fiscal quarter, including
those obtained by application of the proceeds of such additional Debt, and owned by the Operating Partnership or any of its Subsidiaries as of the date of incurrence of such additional Debt; and 


 

	 	“(3)	the aggregate amount of any securities offering proceeds received by (or contributed to) the Operating Partnership or any of its Subsidiaries since the end of such fiscal quarter (to the extent that such proceeds were
not used to acquire such real estate assets or mortgages receivable (or interests therein) or used to reduce Debt of the Operating Partnership or any of its Subsidiaries), including the proceeds obtained from the incurrence of such additional Debt,


 “determined on a consolidated basis in accordance with GAAP. 

“For clarity, it is understood and agreed that, for purposes of this Section 1011, Debt of a Person existing at the time such Person
is merged or consolidated with or into the Operating Partnership or any of its Subsidiaries or becomes a Subsidiary of the Operating Partnership shall be deemed to have been incurred by the Operating Partnership or such Subsidiary, as the case may
be, on the date of such merger or consolidation or the date such Person becomes a Subsidiary of the Operating Partnership, as the case may be. 
  

	 	“Section 1012.	Ratio of Consolidated Income Available for Debt Service to Annual Debt Service Charge. 


“The Operating Partnership will not, and will not cause or permit any of its Subsidiaries to, incur any Debt if the ratio of Consolidated
Income Available for Debt Service to the Annual Debt Service Charge for the four consecutive fiscal quarters most recently ended prior to the date on which such additional Debt is to be incurred is less than 1.5 to 1, on a pro forma basis after
giving effect to the incurrence of such additional Debt and to the application of the proceeds thereof, determined on a consolidated basis in accordance with GAAP and calculated on the assumptions that:


  
 13 









	 	“(1)	such additional Debt and any other Debt incurred by the Operating Partnership or any of its Subsidiaries since the first day of such four quarter period had been incurred, and the application of the proceeds therefrom
(including to repay or retire other Debt) had occurred, on the first day of such period, 

  

	 	“(2)	the repayment or retirement of any other Debt of the Operating Partnership or any of its Subsidiaries since the first day of such four quarter period had occurred on the first day of such period (except that, in making
such computation, the amount of Debt under any revolving credit facility, line of credit or similar facility shall be computed based upon the average daily balance of such Debt during such period), and 


 

	 	“(3)	in the case of any acquisition or disposition by the Operating Partnership or any of its Subsidiaries of any asset or group of assets, in any such case with a fair market value (determined in good faith by the Operating
Partnership’s Board of Directors) in excess of $1,000,000, since the first day of such four quarter period, whether by merger, purchase or sale of Capital Stock or assets, or otherwise, such acquisition or disposition had occurred as of the
first day of such period with the appropriate adjustments with respect to such acquisition or disposition being included in such pro forma calculation. 


“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 Annual Debt Service Charge, the interest rate on such Debt shall be computed on a pro forma basis as if the average rate which would have been in
effect during the entire such four quarter period had been the applicable rate for the entire such period. 
 “For clarity, it is
understood and agreed that, for purposes of this Section 1012, Debt of a Person existing at the time such Person is merged or consolidated with or into the Operating Partnership or any of its Subsidiaries or becomes a Subsidiary of the
Operating Partnership shall be deemed to have been incurred by the Operating Partnership or such Subsidiary, as the case may be, on the date of such merger or consolidation or the date such Person becomes a Subsidiary of the Operating Partnership,
as the case may be. 
  

	 	“Section 1013.	Limitation on Incurrence of Secured Debt. 

 “The Operating Partnership will not, and
will not cause or permit any of its Subsidiaries to, incur any Debt secured by a Lien upon any property or assets of the Operating Partnership or any of its Subsidiaries, whether owned as of the date of this Indenture or thereafter acquired
(“Secured Debt”), if, immediately after giving effect to the incurrence of such additional Secured Debt and the application of the proceeds thereof on a pro forma basis, the aggregate principal amount of all outstanding Secured
Debt of the Operating Partnership and its Subsidiaries on a consolidated basis determined in accordance with GAAP is greater than 40% of the sum of (without duplication): 
  

	 	“(1)	Adjusted Total Assets as of the end of the most recent fiscal quarter prior to the incurrence of such additional Debt; 


  
 14 









	 	“(2)	the aggregate purchase price of any real estate assets or mortgages receivable (or interests therein) acquired by the Operating Partnership or any of its Subsidiaries since the end of such fiscal quarter, including
those obtained by application of the proceeds of such additional Debt, and owned by the Operating Partnership or any of its Subsidiaries as of the date of incurrence of such additional Debt; and 


 

	 	“(3)	the aggregate amount of any securities offering proceeds received by (or contributed to) the Operating Partnership or any of its Subsidiaries since the end of such fiscal quarter (to the extent that such proceeds were
not used to acquire such real estate assets or mortgages receivable (or interests therein) or used to reduce Debt of the Operating Partnership or any of its Subsidiaries), including the proceeds obtained from the incurrence of such additional Debt,


 determined on a consolidated basis in accordance with GAAP. 

“For clarity, it is understood and agreed that, for purposes of this Section 1013, Debt of a Person existing at the time such Person
is merged or consolidated with or into the Operating Partnership or any of its Subsidiaries or becomes a Subsidiary of the Operating Partnership shall be deemed to have been incurred by the Operating Partnership or such Subsidiary, as the case may
be, on the date of such merger or consolidation or the date such Person becomes a Subsidiary of the Operating Partnership, as the case may be. 

“Section 1014. Maintenance of Unencumbered Total Asset Value. 

“The Operating Partnership and its Subsidiaries, determined on a consolidated basis in accordance with GAAP, will at all times maintain
an Unencumbered Total Asset Value in an amount not less than 150% of the aggregate principal amount of all of outstanding Unsecured Debt of the Operating Partnership and its Subsidiaries, determined on a consolidated basis in accordance with GAAP.

 “For clarity, it is understood and agreed that, for purposes of this Section 1014, Debt of a Person existing at the time such
Person is merged or consolidated with or into the Operating Partnership or any of its Subsidiaries or becomes a Subsidiary of the Operating Partnership shall be deemed to have been incurred by the Operating Partnership or such Subsidiary, as the
case may be, on the date of such merger or consolidation or the date such Person becomes a Subsidiary of the Operating Partnership, as the case may be. 

“Section 1015. Payment of Taxes and other Claims. 

“The Operating Partnership will pay or discharge or cause to be paid or discharged, before the same shall become delinquent: 

 

	 	“(1)	all taxes, assessments and governmental charges levied or imposed upon it or any of its Subsidiaries or upon any income, profits, property or assets of it or any of its Subsidiaries; and 


  
 15 









	 	“(2)	all lawful claims for labor, materials and supplies which, if unpaid, might by law become a Lien upon its property or assets or the property or assets of any of its Subsidiaries, 


“provided, however, that the Operating Partnership will not be required to pay or discharge or cause to be paid or discharged any such tax, assessment,
charge or claim (a) whose amount, applicability or validity is being contested in good faith by appropriate proceedings or (b) if the non-payment of any such taxes, assessments, charges or claims would not, individually or in the
aggregate, reasonably be expected to have a material adverse effect on the ability of the Operating Partnership to pay when due the principal of, and premium, if any, and interest on the Notes. 

 

	 	“Section 1016.	Provision of Financial Information. 

 “Whether or not the Operating Partnership is
subject to Section 13 or 15(d) of the Exchange Act, for so long as any Notes are Outstanding under this Indenture, the Operating Partnership shall, to the extent permitted under the Exchange Act, file with the Commission the annual reports,
quarterly reports and other documents which it would have been required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act if it were so subject, on or prior to the respective dates (each, a “Required Filing
Date”) by which it would have been required to file such documents if it were so subject. In addition: 
  

	 	“(1)	if the Operating Partnership is not subject to Section 13 or 15(d) of the Exchange Act, the Operating Partnership shall, not later than 15 days after each Required Filing Date, transmit by mail to all Holders
of Notes Outstanding under this Indenture, as their names and addresses appear in the Security Register for the Notes, without cost to such holders, copies of the annual reports, quarterly reports and other documents which it would have been
required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act if it were subject to such Sections; provided that the Operating Partnership shall not be required to mail any such report or other document to Holders of
Notes if such report or other document is publicly available on the Commission’s or the Operating Partnership’s website (provided that within five days after the first time that the Operating Partnership shall make any such reports or
documents publicly available on the Operating Partnership’s website, it will disseminate a press release or similar public announcement (using such means of dissemination that is at the time customary for public companies in the United States
of America) announcing the availability of such reports and other documents on such website and providing the internet address of such website); 

  

	 	“(2)	the Operating Partnership shall, whether or not it is subject to Section 13 or 15(d) of the Exchange Act, not later than 15 days after each Required Filing Date, file with the Trustee copies of the annual
reports, quarterly reports and other documents which it would have been required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act if it were subject to those Sections; and 


  
 16 









	 	“(3)	if filing of any such report or other document required by any of the foregoing provisions to be filed with the Commission is not permitted under the Exchange Act, the Operating Partnership shall, promptly upon written
request and payment of reasonable costs of duplication and delivery, supply copies of such report or other document to any prospective Holder of Notes (or, in the case of a Global Security evidencing any Notes, any prospective owner of a beneficial
interest in such Global Security); provided that the Operating Partnership shall not be required to supply any such report or other document to a prospective owner or Holder if such report or other document is publicly available on the
Commission’s or the Operating Partnership’s website. 

 “Any report or other document which the Operating
Partnership is required to mail, file or supply to any Person pursuant to clause (1), (2) or (3) of this Section 1016 may instead be sent to such Person by email if such Person shall have consented in writing (including by email)
to email delivery and such email is sent to such Person at such email address as such Person may provide from time to time by notice to the Trustee or, in the case of clause (2) of this Section 1016, as the Trustee may provide from time to
time by notice to the Operating Partnership. 
  

	 	“Section 1017.	Existence of CRLP. 

 “Except as permitted under Section 1018(D), at such times
(and only such times), if any, as CRLP is required, pursuant to this Indenture, to guarantee the Notes, CRLP shall do or cause to be done all things necessary (i) to preserve and keep in full force and effect its existence (partnership or
other) and (ii) to preserve and keep in full force and effect its rights (under its partnership agreement or other organizational documents, as the case may be, and its statutory rights), licenses and franchises; provided, however, that CRLP
shall not be required to preserve any such right, license or franchise if the Board of Directors of the Operating Partnership determines that the preservation thereof is no longer desirable in the conduct of the business of CRLP. 

 

	 	“Section 1018.	Springing Subsidiary Guarantees by CRLP. 

 “(A) Subsidiary Guarantees. So
long as Notes are Outstanding under this Indenture, neither the Operating Partnership nor the Guarantor will cause, permit or suffer CRLP to Guaranty any Unsecured Debt of the Operating Partnership that is outstanding under the Principal Credit
Agreement (the “Guaranteed Debt”) unless (1) CRLP, the Operating Partnership and the Guarantor shall contemporaneously execute and deliver to the Trustee a supplemental indenture substantially in the form attached as
Annex B to the Second Supplemental Indenture (a “Subsidiary Guarantee Supplemental Indenture”) (the Trustee may, but need not be, a party to such Subsidiary Guarantee Supplemental Indenture) providing for CRLP’s guarantee
of the Notes as set forth in Article Seventeen of this Indenture and in the Subsidiary Guarantees, if any, of CRLP endorsed on the certificates evidencing the Notes and pursuant to which CRLP shall become a party to this Indenture and (2) if
such Guaranteed Debt is: 

  
 17 









	 	“(a)	pari passu in right of payment with the Notes, then CRLP’s Guaranty of such Guaranteed Debt shall be pari passu in right of payment with, or subordinated in right of payment to, its Subsidiary Guarantee
of the Notes, or 

  

	 	“(b)	subordinated in right of payment to the Notes, then CRLP’s Guaranty of such Guaranteed Debt shall be subordinated in right of payment to its Subsidiary Guarantee of the Notes to at least the extent that the
Guaranteed Debt is subordinated in right of payment to the Notes. 

 “In the event that CRLP is required to enter into a
Subsidiary Guarantee Supplemental Indenture, the Operating Partnership and the Guarantor shall deliver to the Trustee an Officer’s Certificate of the Operating Partnership and the Guarantor and an Opinion of Counsel, in each case to the effect
set forth in Section 903 (which Officer’s Certificates and Opinion of Counsel shall expressly refer to and cover such Subsidiary Guarantee Supplemental Indenture as contemplated by Section 903), and to the further effect that the
Subsidiary Guarantees of CRLP to be endorsed on the certificates evidencing the Notes have been duly authorized by CRLP and, when executed by CRLP and endorsed on Notes which have been executed and delivered by the Operating Partnership and
authenticated by the Trustee, will constitute valid and binding obligations of CRLP, enforceable against CRLP in accordance with their terms, subject to customary exceptions; and the Operating Partnership shall deliver to the Trustee a Board
Resolution of CRLP authorizing and approving the form and terms of the Subsidiary Guarantee Supplemental Indenture, this Indenture and of CRLP’s Subsidiary Guarantees to be endorsed on the certificates evidencing the Notes and further
authorizing CRLP to execute, deliver and perform its obligations under the Subsidiary Guarantee Supplemental Indenture, this Indenture and its Subsidiary Guarantees endorsed on any Notes. 

 

	 	“(B)	Suspension of Subsidiary Guarantee and Subsidiary Guarantor Covenant. If on any date: 

  

	 	“(a)	(i) either (A) the Principal Credit Agreement does not include any covenant or agreement that requires or, upon the occurrence of specified events or conditions, would require CRLP to Guaranty any Unsecured Debt of
the Operating Partnership that is or thereafter may be outstanding under the Principal Credit Agreement or (B) there is no Principal Credit Agreement (as determined, reasonably and in good faith, by the Board of Directors of the Operating
Partnership taking into account the factors described in the definition of “Principal Credit Agreement” and evidenced by an Officer’s Certificate of the Operating Partnership delivered to the Trustee), (ii) no Guaranty by CRLP of
any Unsecured Debt of the Operating Partnership that is outstanding under the Principal Credit Agreement shall be in effect, and (iii) no Event of Default and no event which, after notice or lapse of time or both, would become an Event of
Default shall have occurred and be continuing, or 

  

	 	“(b)	 CRLP is not a Significant Subsidiary of either the Operating Partnership or the Guarantor,




  
 18 








 “(the satisfaction of the conditions described in subparagraph (a) or (b) above being referred to
as a “Subsidiary Guarantee Suspension Event” and any date on which a Subsidiary Guarantee Suspension Event shall occur being referred to as a “Subsidiary Guarantee Suspension Date”), then, effective as of such
Subsidiary Guarantee Suspension Date, the Operating Partnership and the Guarantor shall be released, solely insofar as relates to the Notes, from their obligations under Sections 1018(A) and 1018(D) (such provisions being referred to as the
“Suspended Covenants”), and CRLP shall be released from its obligations under its Subsidiary Guarantee, if any, of the Notes and, solely insofar as relates to the Notes, from all of its other obligations, if any, under this
Indenture; provided, however, that, if on any date after a Subsidiary Guarantee Suspension Event, any of the conditions set forth in clauses (i) or (ii) of subparagraph (a) above (if the applicable Subsidiary Guarantee Suspension
Event shall have occurred as a result of the satisfaction of the conditions set forth in such subparagraph (a)) or the condition set forth in subparagraph (b) above (if the applicable Subsidiary Guarantee Suspension Event shall have
occurred as a result of the satisfaction of the condition set forth in such subparagraph (b)) shall not continue to be satisfied, then, effective as of such date (a “Subsidiary Guarantee Reinstatement Date”), the Suspended
Covenants will be reinstated and if, after giving effect to such reinstatement, CRLP is required to guarantee the Outstanding Notes pursuant to the provisions of Section 1018(A), then CRLP’s Subsidiary Guarantee of the Notes and its other
obligations under this Indenture with respect to the Notes shall be reinstated effective as of the Subsidiary Guarantee Reinstatement Date or, if CRLP shall not have entered into a Subsidiary Guarantee Supplemental Indenture as contemplated by this
Section 1018, CRLP, the Operating Partnership and the Guarantor shall, as of the Subsidiary Guarantee Reinstatement Date, enter into a Subsidiary Guarantee Supplemental Indenture (the Trustee may, but need not be, a party to such Subsidiary
Guarantee Supplemental Indenture) and CRLP shall provide its Subsidiary Guarantee of the Notes (all in a manner contemplated by the provisions of Section 1018(A)) and, thereafter, the obligations of the Operating Partnership and the Guarantor
under the Suspended Covenants and, if applicable, CRLP’s obligations under its Subsidiary Guarantee of the Notes and under this Indenture with respect to the Notes will be and remain in effect unless and until the conditions set forth in
subparagraph (a) or subparagraph (b) above are subsequently satisfied (in which event, effective as of the date such conditions are subsequently satisfied, the Operating Partnership and the Guarantor will be released, solely insofar as
relates to the Notes, from their respective obligations under the Suspended Covenants and CRLP shall be released from its obligations under its Subsidiary Guarantee, if any, of the Notes and, solely insofar as relates to the Notes, from all of its
other obligations, if any, under this Indenture until such time as any of the conditions set forth in clauses (i) or (ii) of subparagraph (a) above (if the applicable Subsidiary Guarantee Suspension Event shall have occurred as a
result of the satisfaction of the conditions set forth in such subparagraph (a)) or the condition set forth in subparagraph (b) above (if the applicable Subsidiary Guarantee Suspension Event shall have occurred as a result of the
satisfaction of the condition set forth in such subparagraph (b)) shall not continue to be satisfied, in which case the Suspended Covenants and, if required as provided above in this paragraph, CRLP’s Subsidiary Guarantee and CRLP’s
obligations under this Indenture with respect to the Notes shall be reinstated or CRLP shall enter into such a Subsidiary Guarantee Supplemental Indenture and provide its Subsidiary Guarantee of the Notes, as the case may be); provided, however,
that no default or Event of Default under this Indenture with respect to the Notes or breach of any kind under this Indenture with respect to the Notes shall be deemed to have existed or occurred under this Indenture, the Notes or the Subsidiary
Guarantee, if any, of 

  
 19 








 
the Notes with respect to the Suspended Covenants based on, and none of the Operating Partnership, the Guarantor or CRLP shall, with respect to the Suspended Covenants and solely insofar as
relates to the Notes, bear any liability for, any actions taken or events occurring during a Subsidiary Guarantee Suspension Period, regardless of whether such actions or events would have been permitted if the Suspended Covenants remained in effect
during such Subsidiary Guarantee Suspension Period. The period of time from and including a Subsidiary Guarantee Suspension Date to but excluding the applicable Subsidiary Guarantee Reinstatement Date is hereinafter referred to as a
“Subsidiary Guarantee Suspension Period.” For purposes of clarity, it is understood and agreed that there may be one or more Subsidiary Guarantee Suspension Periods and one or more Subsidiary Guarantee Reinstatement Dates. 

“(C) Release of Subsidiary Guarantee and Subsidiary Guarantor Covenant. In the event of (a) any consolidation or merger of
CRLP into the Operating Partnership in a transaction in which the Operating Partnership is the continuing or resulting Person or (b) any sale, assignment, transfer or other conveyance (other than a lease) of all or substantially all of
CRLP’s assets to the Operating Partnership in any transaction or series of related transactions, the Operating Partnership and the Guarantor shall be released, solely insofar as relates to the Notes, from their obligations set forth under this
Section 1018 and CRLP shall be released from its obligations under its Subsidiary Guarantee, if any, of the Notes and, solely insofar as relates to the Notes, from all of its other obligations, if any, under this Indenture. 

“CRLP shall be released from its obligations under its Subsidiary Guarantee, if any, of the Notes and, solely insofar as relates to the
Notes, from all of its other obligations, if any, under this Indenture (i) if the Operating Partnership shall have effected legal defeasance or covenant defeasance with respect to the Notes pursuant to Section 402 or (ii) if this
Indenture shall have ceased to be of further effect with respect to the Notes upon compliance by the Operating Partnership with the provisions set forth in Section 401, except in each case for such obligations which Section 402 or 401, as
the case may be, expressly provides shall remain in effect notwithstanding any such legal defeasance, covenant defeasance or satisfaction and discharge, as the case may be. In the event of any such legal defeasance or covenant defeasance with
respect to the Notes or in the event that this Indenture ceases to be of further effect with respect to the Notes pursuant to Section 401, then, in addition to the consequences thereof set forth above in this paragraph and in Section 402
or 401, as the case may be, the Operating Partnership and the Guarantor shall also be released, solely insofar as relates to the Notes, from their respective obligations described under this Section 1018. 

“CRLP shall be released from its obligations under its Subsidiary Guarantee, if any, of the Notes and, solely insofar as relates to the
Notes, from all of its other obligations, if any, under this Indenture upon: 
  

	 	“(i)	the sale, transfer or other disposition of Capital Stock of CRLP if, as a result of such sale, transfer or disposition, CRLP shall no longer be a Subsidiary of either the Operating Partnership or the Guarantor, or


  

	 	“(ii)	 the consolidation or merger of CRLP with or into any other Person (other than the Operating Partnership or the Guarantor or any of their respective
Subsidiaries) if, as a result of such consolidation or merger, CRLP shall no 



  
 20 









	 	
longer be a Subsidiary of either the Operating Partnership or the Guarantor (provided that this clause (ii) shall not limit the provisions set forth in the first paragraph of this
Section 1018(C) relating to the effect of a consolidation or merger of CRLP into the Operating Partnership), or 

  

	 	“(iii)	a liquidation or dissolution of CRLP, or 

  

	 	“(iv)	the release or discharge of all Guaranteed Debt, except a discharge or release by or as a result of payment under CRLP’s Guaranty of any such Guaranteed Debt (provided that this clause (iv) shall not affect
any subsequent requirement that CRLP guarantee the Notes as contemplated by the provisions set forth in Section 1018(A) above and, provided, further, that the first sentence of the third paragraph of Section 1701 shall survive any such
release of CRLP from its obligations under this Indenture pursuant to this clause (iv) and remain in full force and effect). 


“(D) Consolidation, Merger and Sale of Assets of CRLP. During such times, and only such times, as CRLP is required to guarantee
the Notes pursuant to the provisions set forth in this Section 1018, neither the Operating Partnership nor the Guarantor will cause or permit CRLP, in any transaction or series of related transactions, to consolidate or merge with or into any
Person or sell, lease, assign, transfer or otherwise convey all or substantially all of its assets to any Person unless: 
  

	 	“(a)	either (1) in the case of a merger, CRLP shall be the continuing Person or (2) the successor Person (if other than CRLP) formed by or resulting from such consolidation or into which CRLP is merged or to which
such sale, lease, assignment, transfer or other conveyance of all or substantially all of CRLP’s assets is made (i) is the Operating Partnership or (ii) shall be an entity organized and existing under the laws of the United States of
America, any state thereof or the District of Columbia and (solely in the case of this clause (ii)) shall, by an indenture supplemental hereto, in form and substance reasonably satisfactory to the Trustee, executed by such successor Person and
the other parties to this Indenture and delivered to the Trustee, expressly assume the due and punctual payment of all amounts payable under the Subsidiary Guarantees of the Notes and the due and punctual performance and observance of every other
obligation in this Indenture with respect to the Notes and the Subsidiary Guarantees, if any, endorsed on the certificates evidencing any Notes on the part of CRLP to be performed or observed; 


 

	 	“(b)	immediately after giving effect to such transaction or series of related transactions, as the case may be, and treating any Debt which becomes an obligation of CRLP, the Operating Partnership or any of their respective
Subsidiaries as a result of such transaction as having been incurred by it at the time of such transaction, no Event of Default, and no event which, after notice or lapse of time or both, would become an Event of Default, shall have occurred and be
continuing; and 


  
 21 









	 	“(c)	the Operating Partnership and the Guarantor shall have delivered to the Trustee an Officer’s Certificate of the Operating Partnership and an Officer’s Certificate of the Guarantor and an Opinion of Counsel,
each stating that such consolidation, merger, sale, assignment, transfer, lease or other conveyance and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture comply with this Section 1018(D)
and that all conditions precedent herein provided for relating to such transaction have been complied with; 

 “provided, however, that
the provisions of clause (b) above shall not be applicable if the successor Person formed by or resulting from any such consolidation or into which CRLP is merged or to which such sale, lease, assignment, transfer or other conveyance of all or
substantially all of CRLP’s assets is made is the Operating Partnership. 
 “Upon any consolidation by CRLP with or merger of CRLP
into any Person or any sale, lease, assignment, transfer or other conveyance of all or substantially all of the assets of CRLP to any Person in accordance with the provisions set forth in the immediately preceding paragraph: 

 

	 	“(a)	the successor Person formed by or resulting from such consolidation or into which CRLP is merged or to which such sale, lease, assignment, transfer or other conveyance is made shall (solely insofar as relates to the
Notes) succeed to, and be substituted for, and may exercise every right and power of, CRLP under this Indenture with respect to the Notes with the same effect as if such successor Person had been named as CRLP under this Indenture; and


  

	 	“(b)	except in the case of a lease, the predecessor Person shall be released (solely insofar as relates to the Notes) from all obligations and covenants under this Indenture and its Subsidiary Guarantee, if any, of the
Notes.”

respect to the Outstanding Notes and, in the case of CRLP, any Subsidiary Guarantees thereof on the date the conditions set forth in clause (4) of this Section 402 are satisfied (hereinafter, “legal defeasance”). For this
purpose, such legal defeasance means that the Operating Partnership shall be deemed to have paid and discharged the entire indebtedness represented by the Outstanding Notes, which shall thereafter be deemed to be “Outstanding” only for the

Partnership and the Guarantor and, if applicable and except as provided below, CRLP may omit to comply with, and shall have no liability in respect of, any term, condition or limitation set forth in any such Section, or, in the case of CRLP and

Section, or, in the case of CRLP and except as provided below, to any such Subsidiary Guarantee or such other obligations of CRLP under this Indenture with respect to the Notes, or by reason of reference in any such Section, or, in the case of CRLP
and except as provided below, in any such Subsidiary Guarantee or any other provision of this Indenture applicable (insofar as concerns the Notes) to CRLP, to any other provision herein or in any other document, and such omission to comply shall not
constitute a default or an Event of Default under Section 501(3) or, in the case of any Subsidiary Guarantee of the Notes and except as provided below, Section 501(5) or otherwise, but, except as specified above, the remainder of this

	 	“(3)	 default in the performance or breach of any covenant or warranty of the Operating Partnership or the Guarantor or, subject to the proviso set forth
below in this clause (3), CRLP in this Indenture (other than a covenant or warranty for which the consequences of breach or nonperformance are addressed elsewhere in this Section 501 or a covenant or warranty which has expressly been included

evidencing any of the Notes, and continuance of such default or breach (without such default or breach having been waived in accordance with the provisions of this Indenture) for a period of 60 days after there has been given, by registered or
certified mail, to the Operating Partnership by the Trustee or to the Operating Partnership and the Trustee by the Holders of at least 25% in aggregate principal amount of the Outstanding Notes a written notice specifying such default or breach and

any time while it is required, pursuant to this Indenture, to guarantee the Notes (and any Event of Default with respect to the Notes resulting from such default or breach by CRLP) will be deemed to have been cured at such time, if any, as CRLP
shall be released, in accordance with the applicable provisions of this Indenture, from its obligation to guarantee the Notes); or

guarantor) (in each case including a default with respect to any Outstanding Securities of any other series), whether such indebtedness exists on the date of this Indenture or shall be created, assumed or incurred thereafter, which results in such
indebtedness being declared or otherwise becoming due and payable prior to the date on which it would otherwise have become due and payable, or which constitutes a failure to pay when due (after expiration of any applicable grace period) such

 Section 4.28. Amendment to Other Sections of Article Ten of the Original Indenture.
Article Ten of the Original Indenture is hereby amended, but only insofar as relates to the Notes, by amending and restating Sections 1005 through 1009 thereof to read in full as follows (and the Table of Contents in the Original Indenture is
amended to revise the titles of Sections 1005 and 1009 indicated below in such Table of Contents to conform to the titles set forth below): 

“Section 1005. Existence of the Operating Partnership and the Guarantor. 

“Except as permitted under Article Eight, (i) each of the Operating Partnership and the Guarantor shall do or cause to be done all
things necessary to preserve and keep in full force and effect its existence (corporate, partnership or other, as the case may be) and (ii) the Operating Partnership shall do or cause to be done all things necessary to preserve and keep in full
force and effect its rights (under its partnership agreement or other organizational documents, as the case may be, and its statutory rights), licenses and franchises; provided, however, that the Operating Partnership shall not be required to
preserve any such right, license or franchise if the Board of Directors of the Operating Partnership determines that the preservation thereof is no longer desirable in the conduct of the business of the Operating Partnership. 

“Section 1006. Maintenance of Properties. 

“The Operating Partnership will cause all of its material properties and the material properties of each of its Subsidiaries that are
used or useful in the conduct of its business or the business of any of its Subsidiaries to be maintained and kept in good condition, repair and working order, normal wear and tear, casualty and condemnation excepted, and supplied with all necessary
equipment and will cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereof (and the Operating Partnership may take out of service for a period of time any of its or its Subsidiaries’ properties that
have been condemned or suffered any loss due to casualty in order to make such repairs, betterments and improvements), all as in its judgment may be necessary so that the business carried on in connection therewith may be properly and advantageously
conducted at all times; provided, however, notwithstanding anything in this Indenture to the contrary, the Operating Partnership may (i) discontinue the maintenance of any of such properties if such discontinuance is, in the reasonable judgment
of the Operating Partnership, desirable in the conduct of its business or the business of any Subsidiary of the Operating Partnership and not disadvantageous in any material respect to the Holders of any Notes Outstanding under this Indenture,
(ii) remove, or cause its Subsidiaries to remove, permanently any property that has been condemned or suffered a loss due to casualty based on the Operating Partnership’s reasonable judgment that such removal is in the best interest of the
Operating Partnership or (iii) sell or otherwise dispose of, or cause its Subsidiaries to sell or otherwise dispose of, for value any of their respective properties in the ordinary course of business. 

“Section 1007. Insurance. 

“The Operating Partnership will, and will cause each of its Subsidiaries to, keep in force upon all of its insurable properties insurance
policies carried with reputable companies in such amounts and covering such risks as is customary in the industry in which the Operating Partnership and its Subsidiaries do business in accordance with prevailing market conditions and availability.

 “Section 1008. Waiver of Certain Covenants. 

“Each of the Operating Partnership and the Guarantor and, if CRLP shall have become a party to this Indenture pursuant to a Subsidiary
Guarantee Supplemental Indenture and shall not have been released, in accordance with the applicable provisions of this Indenture, from its obligations under this Indenture with respect to the Notes, CRLP may omit in any particular instance to
comply with any term, provision or condition set forth in clause (ii) of Section 1005, Sections 1006 and 1007, Sections 1011 through 1016, inclusive, clause (ii) of Section 1017 and Section 1018, but in each case
solely insofar as relates to the Notes and, if expressly provided pursuant to Section 301, any additional covenants applicable to the Notes if, before the time for such compliance, the Holders of at least a majority in aggregate principal
amount of the Outstanding Notes, by Act of such Holders, either shall waive such compliance in such instance or generally shall have waived compliance with such term, provision or condition, but no such waiver shall extend to or affect such term,
provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Operating Partnership, the Guarantor and, if applicable, CRLP, as the case may be, and the duties of the Trustee
in respect of any such term, provision or condition shall remain in full force and effect. 
 “Section 1009. Operating
Partnership, Guarantor and, if applicable, CRLP Statement as to Compliance. 
 “Each of the Operating Partnership, the Guarantor
and, subject to the proviso to this paragraph, CRLP shall deliver to the Trustee, within 120 days after the end of each fiscal year, a written statement (which need not be contained in or accompanied by an Officer’s Certificate) signed by
the principal executive officer, the principal financial officer or the principal accounting officer of the Operating Partnership, the Guarantor or CRLP, as applicable, stating whether or not, to the best of his or her knowledge, the Operating
Partnership, the Guarantor and CRLP, as applicable, are in compliance with all terms, conditions, covenants and other provisions of this Indenture, the Securities and, if applicable, any Subsidiary Guarantees (without regard to notice requirements
or periods of grace) and if the Operating Partnership, the Guarantor or CRLP, as applicable, shall be in default, specifying all such defaults and the nature and status thereof of which he or she may have knowledge; provided that the foregoing
provisions of this paragraph, insofar as they relate to CRLP, shall only be applicable if either (i) CRLP shall have become a party to this Indenture pursuant to a Subsidiary Guarantee Supplemental Indenture and shall not have been released, in
accordance with the applicable provisions of this Indenture, from all of its obligations under this Indenture with respect to the Notes or (ii) CRLP is required by the Trust Indenture Act to comply with such provisions.” 

Section 4.29. Amendment to Section 1107 of the Original Indenture. The last sentence of Section 1107 of the Original
Indenture is hereby amended, but solely insofar as relates to the Notes, by replacing the words “Guarantee” and “the Guarantor” each time such words appear in that sentence with “Subsidiary Guarantee” and

 41 








 Section 4.30. Amendment to Section 1503 of the Original Indenture. The last
sentence of Section 1503 of the Original Indenture is hereby amended, but solely insofar as relates to the Notes, by replacing the words “the Guarantor” each time such words appear in that sentence with the text “CRLP”. 

Section 4.31. Amendment to Section 1504 of the Original Indenture. The last paragraph of Section 1504 of the Original
Indenture is hereby amended, but solely insofar as relates to the Notes, by replacing the word “Guarantees” appearing in that paragraph with the words “Subsidiary Guarantees”. 

Section 4.32. Article Seventeen. The Original Indenture is hereby amended and supplemented, but only insofar as relates to the
Notes, by adding the following new Article Seventeen to appear immediately after Article Sixteen of the Original Indenture and to read in full as follows (and the Table of Contents in the Original Indenture is amended, solely insofar as relates to
the Notes, to insert the section numbers and titles of the sections of Article Seventeen in appropriate sequence in such Table of Contents): 

“ARTICLE SEVENTEEN 

“SUBSIDIARY GUARANTEE 

“Section 1701. Subsidiary Guarantee. 

“The provisions of this Article Seventeen shall not become effective until such time as CRLP shall have entered into a Subsidiary
Guarantee Supplemental Indenture as contemplated by Section 1018. By its execution of any such Subsidiary Guarantee Supplemental Indenture, CRLP will be deemed to have acknowledged and agreed that it receives substantial benefits from the
Operating Partnership and the Guarantor and that CRLP is providing its Subsidiary Guarantees for good and valuable consideration, including, without limitation, such substantial benefits. Accordingly, subject to the provisions of this Article
Seventeen, CRLP hereby fully and unconditionally guarantees to each Holder of Notes that are authenticated by the Trustee and delivered by the Trustee or the Operating Partnership that: (i) the principal of, and premium, if any, and interest
on, the Notes shall be duly and punctually paid in full when due, whether at Stated Maturity, upon acceleration, upon redemption or otherwise; (ii) to the extent permitted by applicable law, interest on overdue principal of, and overdue
premium, if any, and interest on, the Notes shall be duly and punctually paid in full when due; and (iii) all other obligations of the Operating Partnership to the Holders of Notes and (solely insofar as it relates to the Notes) to the Trustee
hereunder and under the Notes (including, without limitation, obligations to pay fees, expenses and other charges) shall be duly and punctually paid in full when due or duly and punctually performed, as the case may be, all in accordance with the
terms hereof and thereof, and, in case of any extension of time of payment or renewal of any Notes or any of such other obligations, the same shall be duly and punctually paid in full when due, whether at the Stated Maturity, by acceleration, call
for redemption or otherwise, or duly and punctually performed, as the case may be, in accordance with the terms of the extension or renewal, subject, however, in each case referred to above in this paragraph, to the limitations set forth in
Section 1703 hereof (collectively, the “Subsidiary Guarantee Obligations”). 

  
 42 








 “Subject to the provisions of this Article Seventeen, CRLP hereby agrees, to the extent
permitted by applicable law, that its Subsidiary Guarantee hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or of this Indenture, the absence of any action to enforce the same, any waiver or
consent by any Holder of Notes with respect to any thereof, the entry of any judgment against the Operating Partnership, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or
defense of CRLP. CRLP hereby waives and relinquishes, to the extent permitted by applicable law: (a) any right to require the Trustee, the Holders of Notes or the Operating Partnership (each, a “Subsidiary Guarantee Benefited
Party”) to proceed against the Operating Partnership or any other Person or to proceed against or exhaust any security held by a Subsidiary Guarantee Benefited Party at any time or to pursue any other remedy in any Subsidiary Guarantee
Benefited Party’s power before proceeding against CRLP; (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 Subsidiary Guarantee 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) diligence, presentment, the filing of claims with any court in the event of a merger, consolidation,
bankruptcy, insolvency or dissolution of the Operating Partnership, any right to require a proceeding first against the Operating Partnership and any demand, protest and notice of any kind (except as expressly required by this 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 CRLP, the Operating Partnership, any other Subsidiary Guarantee Benefited Party or
any creditor of CRLP or the Operating Partnership or on the part of any other Person in connection with any obligations the performance of which are hereby guaranteed; (d) any defense based upon an election of remedies by a Subsidiary Guarantee
Benefited Party, including but not limited to an election to proceed against CRLP 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 Subsidiary Guarantee Benefited Party’s election of the application of Section 1111(b)(2) (or any successor provision thereto) of the
Bankruptcy Code; and (g) any defense based on any borrowing or grant of a security interest under Section 364 (or any successor provision thereto) of the Bankruptcy Code. CRLP hereby covenants, to the extent permitted by applicable law,
that the Subsidiary Guarantee of the Notes shall not be discharged except (x) by payment and performance in full of all Subsidiary Guarantee Obligations, including the payment in full of the principal of, and premium, if any, and interest on,
the Notes and all other costs and expenses provided for under this Indenture or (y) as provided in Section 1018(C) or Article Four of this Indenture (subject to survival of certain obligations of CRLP as provided in Section 1018(C),
Article Four and the next succeeding paragraph). 
 “If any Holder of Notes or the Trustee is required by any court or otherwise to
return to either the Operating Partnership or CRLP, or any trustee or similar official acting in relation to either the Operating Partnership or CRLP, any amount paid by the Operating Partnership (at any time while a Subsidiary Guarantee was in
effect with respect to the Notes), or any amount paid by CRLP, to the Trustee or such Holder in respect of the Notes, the Subsidiary Guarantee of the Notes, to the extent theretofore discharged or released, shall, to the extent permitted by
applicable law, be reinstated in full force and effect, it being understood and agreed that, anything in this Indenture to the contrary notwithstanding, the provisions of this sentence shall 

  
 43 








 
survive any release, pursuant to Section 401 or 402 or clause (iv) of the last paragraph of Section 1018(C), of CRLP’s Subsidiary Guarantees of the Notes and of CRLP from its
other obligations under this Indenture with respect to the Notes and remain in full force and effect. CRLP agrees, to the extent permitted by applicable law, that it shall not be entitled to any right of subrogation in relation to the Holders of
Notes in respect of any Subsidiary Guarantee Obligations until payment in full and performance of all such Subsidiary Guarantee Obligations. CRLP agrees, to the extent permitted by applicable law, 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 Five hereof, notwithstanding any stay, injunction or other prohibition preventing such
acceleration in respect of the Subsidiary Guarantee Obligations, and (y) in the event of any acceleration of any such obligations as provided in Article Five hereof, the Subsidiary Guarantee Obligations (whether or not due and payable) shall
forthwith become due and payable by CRLP for the purpose of the Subsidiary Guarantee. 
 “Section 1702. Execution and Delivery
of Notation of Subsidiary Guarantee. 
 “To evidence the Subsidiary Guarantee set forth in Section 1701 hereof with respect to
the Notes, CRLP agrees that a Subsidiary Guarantee may be endorsed on the certificates evidencing any Note that has been or is authenticated and delivered by the Trustee, which Subsidiary Guarantee shall be executed on behalf of CRLP by its
Chairman, its Chief Executive Officer, its President, its Chief Financial Officer or one of its Vice Presidents and by its Treasurer, one of its Assistant Treasurers, its Secretary or one of its Assistant Secretaries (which signatures may be manual
or facsimile) and further agrees that the form and terms of such Subsidiary Guarantee shall be those established by the Second Supplemental Indenture. Any Subsidiary Guarantee endorsed on the certificate evidencing any Note shall be in addition to,
and shall in no way limit, the Subsidiary Guarantee of the Notes pursuant to this Article Seventeen. If CRLP shall become a party to this Indenture pursuant to a Subsidiary Guarantee Supplemental Indenture as contemplated by Section 1018, then,
if any Notes Outstanding at such time are evidenced by one or more Global Securities, the Operating Partnership and CRLP shall use commercially reasonable efforts to cause the applicable Depository (or its custodian or nominee) to exchange such
Global Securities for Global Securities evidencing a like aggregate principal amount of Notes with Subsidiary Guarantees endorsed on such Global Securities; provided, however, that no failure to effect any such exchange shall constitute a default or
Event of Default with respect to the Notes hereunder. 
 “Subsidiary Guarantees endorsed on the certificates evidencing any Note
bearing the manual or facsimile signatures of individuals who were at the time the proper officers of CRLP shall, to the fullest extent permitted by law, bind CRLP, notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Note or did not hold such offices at the date of such Note. 
 “CRLP agrees
that the Subsidiary Guarantee set forth in this Article Seventeen shall remain in full force and effect and apply to all the Notes notwithstanding any failure to endorse, or election not to endorse, on any or all Notes a Subsidiary Guarantee in the
manner contemplated by the first paragraph of this Section 1702. 

  
 44 








 “The delivery of any Note by the Trustee or the Operating Partnership, after the
authentication thereof hereunder, shall constitute due delivery of the Subsidiary Guarantee set forth in this Indenture and the Subsidiary Guarantee, if any, endorsed on such Note on behalf of CRLP. 

“Section 1703. Limitation of Guarantor’s Liability; Certain Bankruptcy Events. 

“(1) CRLP, and by its acceptance hereof each Holder of Notes, hereby confirms that it is the intention of all such parties that the
obligations of CRLP under its Subsidiary Guarantees of the Notes and its other obligations under this Article Seventeen with respect to the Notes not constitute a fraudulent transfer or fraudulent 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 the extent applicable to such Subsidiary Guarantees or other obligations. To effectuate the foregoing intention, the Holders of Notes and
CRLP hereby irrevocably agree that the obligations of CRLP under its Subsidiary Guarantees of the Notes and its other obligations under this Article Seventeen with respect to the Notes shall be limited to the maximum amount as shall, after giving
effect to all other contingent and fixed liabilities of CRLP that are relevant under such laws, result in the obligations of CRLP under its Subsidiary Guarantees of the Notes and its other obligations under this Article Seventeen with respect to the
Notes not constituting a fraudulent transfer or conveyance under such laws. 
 “(2) CRLP hereby covenants and agrees, to the extent
permitted by applicable law, that in the event of the insolvency, bankruptcy, dissolution, liquidation or reorganization of the Operating Partnership, CRLP 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 any Subsidiary Guarantee and, to the extent permitted by applicable law, hereby waives and agrees not to take the benefit of any such stay of execution, whether
under Sections 362 or 105 (or any successors thereto) of the Bankruptcy Code or otherwise. 
 “Section 1704. Suspension
and Release of Subsidiary Guarantees. 
 “Anything in this Indenture or the Subsidiary Guarantees, if any, endorsed on the
certificates evidencing any of the Notes to the contrary notwithstanding, CRLP may be released from its obligations under its Subsidiary Guarantees, if any, of the Notes and, solely insofar as relates to the Notes, from all of its other obligations,
if any, under this Indenture (other than, in the case of any such release pursuant to Section 401, Section 402 or clause (iv) of Section 1018(C), (a) such obligations under this Indenture that Section 401,
Section 402 or clause (iv) of Section 1018(C), as the case may be, expressly provides shall survive any such release and remain in full force and effect and (b) the provisions of the first sentence of the third paragraph of
Section 1701, which shall survive any such release pursuant to Section 401, Section 402 or clause (iv) of Section 1018(C), as the case may be, and remain in full force and effect), all on the terms and subject to the
conditions set forth in Article Four, Section 1018 and the first sentence of the third paragraph of Section 1701.”

 MID-AMERICA APARTMENTS, L.P. 

3.750% Senior Notes due 2024 

Mid-America Apartments, L.P., a Tennessee limited partnership (hereinafter called the “Operating Partnership”, which term includes
any successor thereto under the Indenture referred to below), for value received, hereby promises to pay to •, or registered assigns, the principal sum of • Dollars ($•) on June 15, 2024, and to pay interest thereon from
June 13, 2014 or from the most recent date to which interest has been paid or duly provided for, semi-annually in arrears on June 15 and December 15 of each year (each, an “Interest Payment Date”), commencing
December 15 , 2014, and at Maturity, at the rate of 3.750% per annum, until the principal hereof is paid or duly made available for payment. Interest on this Note shall be calculated on the basis of a 360-day year consisting of twelve
30-day months. The interest so payable and punctually paid or duly provided for on any Interest Payment Date will, as provided in the Indenture, be paid to the Person in whose name this Note (or one or more Predecessor Securities) is registered at
the close of business on the Regular Record Date for such interest, which shall be June 1 or December 1 (whether or not a Business Day), as the case may be, immediately preceding such Interest Payment Date. Any such interest
which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date shall forthwith cease to be payable to the Person who was the Holder hereof on the relevant Regular Record Date by virtue of having been such Holder, and
may be paid to the Person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be
given to the Holder of this Note not less than 10 days prior to such Special Record Date, or may be paid in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such
notice as may be required by such exchange, all as more fully provided in the Indenture. Any principal of, or premium, if any, or interest on this Note which is not paid when due shall, to the extent permitted by applicable law, bear interest from
the date such amount was originally due to the date of payment of such overdue amount at an interest rate per annum equal to the rate of interest borne by this Note. All such interest on overdue amounts shall be payable on demand. 

  
 A-1 








 Payment of the principal of, and premium, if any, and interest on this Note will be made at the
Office or Agency of the Operating Partnership maintained for that purpose in the Borough of Manhattan, The City of New York, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and
private debts; provided, however, that, at the option of the Operating Partnership, interest may be paid by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register or by transfer
to an account maintained by the payee with a bank located in the United States of America; provided, further, that, notwithstanding the foregoing, all payments of principal of, and premium, if any, and interest on Notes in global form
that are registered in the name of a Depository or its nominee (“Global Notes”) shall be made by wire transfer of immediately available funds (unless otherwise required by the Depository) in accordance with the procedures of the
Depository. 
 This Note is one of a duly authorized issue of Securities of the Operating Partnership issued and to be issued in one or more
series under an Indenture dated as of October 16, 2013 (the “Original Indenture”), as amended and supplemented by the Second Supplemental Indenture dated as of June 13, 2014 (the “Second Supplemental Indenture”; the
Original Indenture, as amended and supplemented by the Second Supplemental Indenture and any other indentures supplemental thereto, is hereinafter called the “Indenture”), each among the Operating Partnership, Mid-America Apartment
Communities, Inc., a Tennessee corporation (the “Guarantor,” which term includes any successor thereto under the Indenture), and U.S. Bank National Association, as trustee (herein called the “Trustee”, which term includes any
successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Operating
Partnership, the Guarantor, the Trustee and the Holders of the Notes, and the terms upon which the Notes are, and are to be, authenticated and delivered. This Note is one of the series of Securities designated on the face hereof (such series of
Securities, the “Notes”). Anything herein to the contrary notwithstanding, the Notes are not guaranteed by the Guarantor. 
 Prior
to March 15, 2024, the Notes may be redeemed, at any time in whole or from time to time in part, at the option of the Operating Partnership at a Redemption Price equal to the greater of: 

 

	 	(a)	100% of the principal amount of the Notes to be redeemed, and 

  

	 	(b)	the sum of the present values of the remaining scheduled payments of principal of, and interest on the Notes to be redeemed (exclusive of interest accrued to the applicable Redemption Date) discounted to such Redemption
Date on a semi-annual basis, assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate plus 20 basis points, 


plus, in the case of both clauses (a) and (b) above, accrued and unpaid interest on the principal amount of the Notes being redeemed to, but not
including, such Redemption Date. 
 On and after March 15, 2024, the Notes may be redeemed, at any time in whole or from time to time
in part, at the option of the Operating Partnership at a Redemption Price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest on the principal amount of the Notes being redeemed to, but not including,
such Redemption Date. 
 Notwithstanding the foregoing, installments of interest on Notes that are due and payable on an Interest Payment
Date falling on or prior to a Redemption Date for the Notes will be payable to the Persons who were the Holders of such Notes (or one or more Predecessor Securities) registered as such at the close of business on the relevant Regular Record Dates
according to their terms and the provisions of the Indenture. 
 “Treasury Rate” means (1) the yield, under the heading which
represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15(519)” or any successor publication which is published weekly by the Board of Governors of the Federal
Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the 

  
 A-2 








 
caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the remaining life of the
Notes, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue will be determined and the Treasury Rate will be interpolated or extrapolated from such yields on a straight line basis, rounding to the
nearest month), or (2) if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per annum equal to the semi-annual equivalent yield to maturity of the
Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for the applicable Redemption Date. The Treasury Rate shall be
calculated on the third Business Day preceding the applicable Redemption Date. As used in the immediately preceding sentence and in the definition of “Reference Treasury Dealer Quotations” below, the term “Business Day” means any
day, other than a Saturday or a Sunday, that is not a day on which banking institutions in The City of New York are authorized or required by law, regulation or executive order to close. 

“Comparable Treasury Issue” means, with respect to any Redemption Date for the Notes, the United States Treasury security selected
by the Independent Investment Banker as having an actual or interpolated maturity comparable to the remaining term of the Notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in
pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Notes to be redeemed. 

“Independent Investment Banker” means, with respect to any Redemption Date for the Notes, an independent investment banking
institution of national standing appointed by the Operating Partnership with respect to such Redemption Date. 
 “Comparable Treasury
Price” means, with respect to any Redemption Date for the Notes: 
  

	 	(a)	the average of five Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or 


 

	 	(b)	if the Operating Partnership obtains fewer than five but more than one such Reference Treasury Dealer Quotations for such Redemption Date, the average of all such quotations, or 


 

	 	(c)	if the Operating Partnership obtains only one such Reference Treasury Dealer Quotation for such Redemption Date, that Reference Treasury Dealer Quotation. 


“Reference Treasury Dealer” means with respect to any redemption date for the notes, as determined by the Operating Partnership,
either (a) (i) two primary U.S. Government securities dealer in The City of New York (each, a “Primary Treasury Dealer”) selected jointly by J.P. Morgan Securities LLC, Wells Fargo Securities, LLC and Jefferies LLC and
their respective successors and (ii) three other Primary Treasury Dealers selected by the Operating Partnership or (b) one Primary Treasury Dealer selected by the Operating Partnership and four other Primary Treasury Dealers selected by
the Independent Investment Banker, and four other Primary Treasury Dealers selected by the Independent Investment Banker. 
 “Reference
Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date for the Notes, the average, as determined by the Operating Partnership, of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) quoted in writing to the Operating Partnership by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding such Redemption Date. 

Notice of any redemption by the Operating Partnership will be mailed at least 30 days but not more than 60 days before any
Redemption Date to the Holders of the Notes to be redeemed. If less than all of the Outstanding Notes are to be redeemed, the Trustee shall select the Notes or portions of the Notes (in principal amounts of $2,000 and integral multiples of $1,000 in
excess thereof) to be redeemed by such method as the Trustee shall deem fair and appropriate and, in the case of Global Notes, in accordance with the Depository’s procedures; provided, however, that the unredeemed portion of the principal
amount of any Note being redeemed in part must be an authorized denomination. 

  
 A-3 








 Unless the Operating Partnership defaults in payment of the Redemption Price and accrued unpaid
interest on the Notes or portions thereof called for redemption, on and after any Redemption Date interest will cease to accrue on the Notes or portions hereof called for redemption. 

The Notes are not subject to, and will not be entitled to the benefit of, any sinking fund. 

If an Event of Default with respect to the Notes shall occur and be continuing, the principal of, and accrued and unpaid interest on the Notes
may be declared immediately due and payable in the manner and with the effect provided in the Indenture. 
 The Indenture permits, with
certain exceptions as therein provided, the Operating Partnership, the Guarantor, the Trustee and, if CRLP shall have become a party to the Indenture and shall not have been released, in accordance with the applicable provisions of the Indenture,
from its obligations under the Indenture with respect to the Notes, CRLP, with the consent of the Holders of at least a majority in principal amount of the Outstanding Notes, to modify or amend (but solely insofar as relates to the Notes) any
provisions of the Indenture or of the Notes or, if applicable, CRLP’s Subsidiary Guarantee, if any, of the Notes or the rights of the Holders of the Notes under the Indenture. The Indenture also contains provisions permitting the Holders of at
least a majority in aggregate principal amount of the Notes at the time Outstanding, on behalf of the Holders of all Notes, to waive (but solely insofar as relates to the Notes), compliance by the Operating Partnership and the Guarantor and, if CRLP
shall have become a party to the Indenture, CRLP with certain provisions of the Indenture and certain past defaults under the Indenture with respect to the Notes and their consequences. Any such consent or waiver by the Holder of this Note shall be
conclusive and binding upon such Holder and upon all future Holders of this Note and of any Notes issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made
upon this Note. 
 No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the
obligation of the Operating Partnership, which is absolute and unconditional, to pay the principal of, and premium, if any, and interest on this Note, at the time, place and rate, and in the coin or currency, herein and in the Indenture prescribed.

 As provided in the Indenture and subject to certain limitations set forth therein, the transfer of this Note may be registered on the
Security Register upon surrender of this Note for registration of transfer at the Office or Agency of the Operating Partnership maintained for the purpose in any place where the principal of, and interest on this Note are payable, duly endorsed, or
accompanied by a written instrument of transfer in form satisfactory to the Operating Partnership and the Security Registrar duly executed by the Holder hereof or by his attorney duly authorized in writing, and thereupon one or more new Notes, of
authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 
 The
Notes are issuable only in registered form without Coupons in the denominations of $2,000 and integral multiples of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations set forth therein, the Notes are
exchangeable for a like aggregate principal amount of Notes in any authorized denominations, as requested by the Holders surrendering the same. 

No service charge shall be made for any such registration of transfer or exchange, but the Operating Partnership may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection therewith, other than in certain cases provided in the Indenture. 

Prior to due presentment of this Note for registration of transfer, the Operating Partnership, the Guarantor, any Other Guarantor of the
Notes, the Trustee and any agent of the Operating Partnership, the Guarantor, any such Other Guarantor or the Trustee may treat the Person in whose name this Note is registered in the Security Register as the owner hereof for all purposes, whether
or not any payment with respect to this Note shall be overdue, and none of the Operating Partnership, the Guarantor, any such Other Guarantor, the Trustee or any such agent shall be affected by notice to the contrary. 

  
 A-4 








 The Indenture contains provisions whereby, upon the satisfaction of certain conditions,
(i) the Operating Partnership and, if applicable, CRLP may be discharged from their obligations with respect to the Notes and, if applicable, CRLP’s Subsidiary Guarantees, if any, of the Notes, respectively, and the Operating Partnership,
the Guarantor and, if applicable, CRLP may be discharged from their other respective obligations under the Indenture (in each case subject to certain exceptions) or (ii) the Operating Partnership, the Guarantor and, if applicable, CRLP may be
released from their respective obligations under specified covenants in the Indenture. 
 The Notes may, on the terms and subject to the
conditions set forth in the Indenture, be entitled to the benefits of Subsidiary Guarantees of CRLP and, if that occurs, CRLP may be released from its obligations under its Subsidiary Guarantees of the Notes and its other obligations under the
Indenture with respect to the Notes, but subject under certain circumstances to reinstatement of such Subsidiary Guarantees and obligations and subject to certain other exceptions, all on the terms and subject to the conditions set forth in the
Indenture. Reference is hereby made to the Indenture and, if applicable, any Subsidiary Guarantee endorsed on this Note for a statement of the respective rights, limitations of rights, duties and obligations of CRLP, the Trustee and the Holder
hereof under any such Subsidiary Guarantees of the Notes by CRLP. 
 No recourse under or upon any obligation, covenant or agreement
contained in the Indenture or in this Note, or because of any indebtedness evidenced by any of the foregoing, shall be had against any past, present or future partner, shareholder, member, manager, employee, officer, agent or director, solely in
their capacity as such, of the Operating Partnership or of any of the Operating Partnership’s predecessors or successors, either directly or through the Operating Partnership or any such predecessor or successor, under any rule of law, statute
or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance of this Note by the Holder and as part of the
consideration for the issue of this Note; provided, however, that the foregoing provisions of this paragraph shall not be applicable to, or limit recourse under or upon, any obligation, covenant or agreement of the Guarantor set forth in the
Indenture. 
 This Note shall be governed by and construed in accordance with the laws of the State of New York without regard, to the
extent permitted by applicable law, to the conflicts of law principles of such State other than New York General Obligations Law Section 5-1401. 

All terms used in this Note which are defined in the Indenture and not defined herein shall have the meanings assigned to them in the
Indenture. To the extent that any term defined in the Original Indenture shall have been superseded or replaced, insofar as relates to the Notes, by a term defined in the Second Supplemental Indenture, then, for all purposes of this Note, such term
shall have the meaning specified in the Second Supplemental Indenture. 
 Unless the certificate of authentication hereon has been executed
by or on behalf of the Trustee under the Indenture by the manual signature of one of its authorized signatories, this Note shall not be entitled to any benefits under the Indenture or be valid or obligatory for any purpose.

“Trustee,” which term includes any successor thereto under the Indenture). 
 The obligations of CRLP to the Holders of the Notes
and to the Trustee pursuant to this Subsidiary Guarantee and the Indenture are expressly set forth in Article Seventeen of the Indenture and reference is hereby made to such Indenture for the precise terms of this Subsidiary Guarantee. Without

 THE TERMS OF ARTICLE SEVENTEEN OF THE INDENTURE ARE INCORPORATED HEREIN BY REFERENCE.
