 ANNEX I 

Capitalized terms used in this Annex I and not otherwise defined herein have the same definitions as in the Indenture referred to in
the Officers’ Certificate of which this Annex I constitutes a part. 
  

	(1)	 The Securities of the series established hereby shall be known and designated as the “3.375% Senior
Notes due 2031.” 


  

	(2)	 The aggregate principal amount of the Securities of such series which may be authenticated and delivered under
the Indenture is limited to $500,000,000, except for Securities of such series authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Securities of the same series pursuant to Sections 304, 305, 306 or
1107 of the Indenture. However, such series may be re-opened by the Company, without the consent of or notice to the Holders of the Securities of such series, for the issuance of additional Securities of such
series, from time to time; provided that such additional Securities have the same terms and provisions as the Securities of such series issued on the date (the “Original Issue Date”) of the Officers’ Certificate of which this
Annex I constitutes a part (except for any difference in issue date, issue price, date from which Interest will begin to accrue, Interest accrued prior to the issue date and first Interest Payment Date (as defined below)), and carry the same right
to receive accrued and unpaid Interest, as the Securities of such series theretofore issued; provided, however, that, notwithstanding the foregoing, such series may not be reopened if the Company has effected legal defeasance or covenant defeasance
with respect to the Securities of such series pursuant to Section 402 of the Indenture or has effected satisfaction and discharge with respect to the Securities of such series pursuant to Section 401 of the Indenture. All of the Securities
of such series, including any additional Securities which may be issued upon a re-opening of such series, shall constitute a single series of Securities under the Indenture. 



 

	(3)	 The Securities of such series are to be issuable only as Registered Securities without coupons and may, but
need not, bear a corporate seal. The Securities of such series shall initially be issued in book-entry form and represented by one or more permanent Global Securities of such series, the initial depositary (together with any successors in such
capacity, the “Depositary”) for the Global Securities of such series shall be The Depository Trust Company and the depositary arrangements shall be those employed by whoever shall be the Depositary with respect to the Global
Securities of such series from time to time. Notwithstanding the foregoing, certificated Securities of such series in definitive form may be issued in exchange for Global Securities of such series under the circumstances contemplated by
Section 305 of the Indenture. Except as provided in Section 305 of the Indenture, beneficial owners of interests in a Global Security shall not be entitled to have certificates registered in their names, will not receive or be entitled to
receive physical delivery of certificates in definitive form and will not be considered Holders of such Global Security. 


  

	(4)	 The Securities of such series shall be sold by the Company to the several underwriters named in the
Underwriting Agreement, dated January 14, 2021, for whom Wells Fargo Securities, LLC, BofA Securities, Inc. and Morgan Stanley & Co. LLC are acting as representatives, at a price equal to 98.285% of the principal amount thereof and the
initial price to public of the Securities of such series shall be 98.935% of the principal amount thereof plus accrued Interest from January 26, 2021 if settlement occurs after that date, and underwriting discounts and commissions shall be
0.650% of the principal amount of such Securities. 


  

	(5)	 The final maturity date of the Securities of such series on which the principal thereof is due and payable
shall be February 1, 2031. 



  
 I-1 














	(6)	 The principal of the Securities of such series shall bear Interest at the rate of 3.375% per annum from
January 26, 2021 or from the most recent date to which Interest has been paid or duly provided for, payable semiannually in arrears on February 1 and August 1 (each, an “Interest Payment Date”) of each year,
commencing August 1, 2021, to the Persons in whose names such Securities (or one or more Predecessor Securities) are registered at the close of business on the January 15 and July 15, respectively, immediately prior to such Interest
Payment Dates (each, a “Regular Record Date”) regardless of whether such Regular Record Date is a Business Day. Interest on the Securities of such series will be computed on the basis of a
360-day year of twelve 30-day months. If any principal of, or premium, if any, or Interest on, any of the Securities of such series is not paid when due, then such
overdue principal and, to the extent permitted by law, such overdue premium or Interest, as the case may be, shall bear interest until paid or until such payment is duly provided for at the rate of 3.375% per annum. 



 

	(7)	 The City of Los Angeles, California is hereby designated as a Place of Payment for the Securities of such
series. The place where the principal of and premium, if any, and Interest (including the Redemption Price upon redemption pursuant to Article Eleven of the Indenture) on the Securities of such series shall be payable, where Securities of such
series may be surrendered for the registration of transfer or exchange, and where notices or demands to or upon the Company or the Guarantor in respect of the Securities of such series and the Indenture may be served shall be the office or agency
maintained by the Company for such purpose in The City of Los Angeles, California, which shall initially be an office of the Trustee in The City of Los Angeles, California, which on the date hereof is located at U.S. Bank National Association, 633

Securities of such series and the Holders of the Securities of such series and are hereby incorporated by reference in and made part of the Indenture for the benefit of the Securities of such series and the Holders of the Securities of such series
as if set forth in full therein: 


 The Securities of such series are redeemable at the option of the
Company, at any time or from time to time prior to November 1, 2030 (the “Par Call Date”), either in whole or in part, at a Redemption Price equal to the greater of (i) 100% of the principal amount of the Securities of such
series to be redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal of and Interest (exclusive of Interest accrued to the applicable Redemption Date) on the Securities of such series to be redeemed
assuming that such Securities matured, and that Interest on such Securities was payable, on the Par Call Date discounted to such Redemption Date on a semiannual basis (assuming a 360-day year consisting of
twelve 30-day months) at the Treasury Rate plus 40 basis points, plus in each case accrued and unpaid Interest on the principal amount of the Securities of such series being redeemed to such Redemption Date.

 On and after the Par Call Date, the Securities of such series are redeemable at the option of the Company, at any time or
from time to time, either in whole or in part, at a Redemption Price equal to 100% of the principal amount of the Securities of such series to be redeemed, plus accrued and unpaid Interest on the principal amount of the Securities of such series
being redeemed to the applicable Redemption Date. 
 Notwithstanding the foregoing, installments of Interest that are due and

registered as such at the close of business on the relevant Regular Record Dates according to their terms and the provisions of the Indenture. Written notice of redemption must be given to Holders of the Securities of such series (or portions
thereof) to be redeemed not less than 15 nor more than 60 days prior to the applicable Redemption Date.

 If less than all of the Securities of such series are to be redeemed, the
particular Securities of such series to be redeemed shall be selected in the manner provided in Section 1103 of the Indenture in minimum principal amounts of $2,000 and integral multiples of $1,000 in principal amount in excess thereof;

Notwithstanding the foregoing, the Company shall not redeem the Securities of such series on any date if the principal amount
of the Securities of such series has been accelerated, and such acceleration has not been rescinded or cured on or prior to the applicable Redemption Date as provided in the Indenture. 

The redemption of the Securities of such series shall otherwise be made as provided in the Indenture, including Article Eleven

Federal Reserve System (the “Federal Reserve”) (or, in each case, any companion online data resource published at least weekly by the Federal Reserve) and which establishes yields on actively traded United States Treasury securities
adjusted to constant maturity for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the Par Call Date, yields for the two published maturities most closely corresponding to the
Comparable Treasury Issue shall be determined and the Treasury Rate shall be interpolated or extrapolated from such yields on a straight-line basis, rounding to the nearest month); or (b) if such release (or any successor publication or
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 by the Company using a

Securities matured on the Par Call Date) 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 Life of such
Securities. 
 “Comparable Treasury Price” means, with respect to any Redemption Date for the Securities of such series,
(i) if four Reference Treasury Dealer Quotations are obtained, the average (as calculated by the Company) of the remaining Reference Treasury Dealer Quotations for such Redemption Date after excluding the highest and lowest such Reference
Treasury Dealer Quotations from the four obtained, (ii) if fewer than four but more than one such Reference Treasury Dealer Quotations are obtained, the average (as calculated by the Company) of all such quotations, or (iii) if only one
such Reference Treasury Dealer Quotation is obtained, such Reference Treasury Dealer Quotation.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date with
respect to the Securities of such series, the average (as calculated by the Company) 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 Company by
such Reference Treasury Dealer at 5:00 p.m., New York time, on the third Business Day prior to the date of the notice of redemption. 
  

	(9)	 The Securities of such series shall not be repayable or redeemable at the option of the Holders prior to the
final maturity date of the principal thereof (except as provided in Article Five of the Indenture) and shall not be subject to a sinking fund or analogous provision.

method.

 Additional Covenants 
  

	 	(a)	 Aggregate Debt Test. 



 

	 	(i)	 The Company will not, and will not permit any of its Subsidiaries to, incur any Debt (including without
limitation Acquired Debt) if, immediately after giving effect to the incurrence of such Debt and the application of the proceeds from such Debt on a pro forma basis, the aggregate principal amount of all outstanding Debt of the Company and its
Subsidiaries (determined on a consolidated basis in accordance with GAAP) is greater than 60% of the sum of the following (without duplication): 


  

	 	(A)	 the Total Assets of the Company and its Subsidiaries as of the last day of the then most recently ended fiscal
quarter covered by AAT’s annual or quarterly report most recently furnished to Holders of the Securities or filed with the Commission, as the case may be; and 



 

	 	(B)	 the aggregate purchase price of any real estate assets or mortgages receivable acquired, and the aggregate
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 fiscal
quarter, including the proceeds obtained from the incurrence of such additional Debt. 


  

	 	(ii)	 For purposes of this covenant, Debt will be deemed to be incurred by the Company or any of its Subsidiaries
whenever the Company or such Subsidiary shall create, assume, guarantee or otherwise become liable in respect thereof. 


  

	 	(b)	 Debt Service Test. 


  

	 	(i)	 The Company will not, and will not permit any of its Subsidiaries to, incur any Debt (including without
limitation Acquired Debt) if the ratio of Consolidated Income Available for Debt Service to Annual Debt Service Charge for the period consisting of the four consecutive fiscal quarters ending with the most recently ended fiscal quarter covered in
AAT’s annual or quarterly report most recently furnished to Holders of the Securities or filed with the Commission, as the case may be, prior to the date on which such additional Debt is to be incurred shall have been less than 1.5:1 on a pro
forma basis after giving effect to the incurrence of such Debt and the application of the proceeds from such Debt (determined on a consolidated basis in accordance with GAAP), and calculated on the following assumptions: 



  
 I-5 














	 	(A)	 such Debt and any other Debt (including without limitation Acquired Debt) incurred by the Company or any of its
Subsidiaries since the first day of such four-quarter period had been incurred, and the application of the proceeds from such Debt (including to repay or retire other Debt) had occurred, on the first day of such period; 



 

	 	(B)	 the repayment or retirement of any other Debt of the Company 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 this computation, the amount of Debt under any revolving credit facility, line of credit or similar facility will be computed based upon the average daily
balance of such Debt during such period); and 


  

	 	(C)	 in the case of any acquisition or disposition by the Company or any of its Subsidiaries of any asset or group
of assets with a fair market value in excess of $1.0 million since the first day of such four-quarter period, whether by merger, stock purchase or sale or asset purchase or sale 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. 


  

	 	(ii)	 If the Debt giving rise to the need to make the calculation described in this covenant 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 will be computed on a pro forma basis by applying
the average daily rate which would have been in effect during the entire four-quarter period to the greater of the amount of such Debt outstanding at the end of such period or the average amount of such Debt outstanding during such period. For
purposes of this covenant, Debt will be deemed to be incurred by the Company or any of its Subsidiaries whenever the Company or such Subsidiary shall create, assume, guarantee or otherwise become liable in respect thereof. 



 

	 	(c)	 Secured Debt Test. 


  

	 	(i)	 The Company will not, and will not permit any of its Subsidiaries to, incur any Debt (including without
limitation Acquired Debt) secured by any Lien on any property or assets of the Company or any of its Subsidiaries, whether owned on the Original Issue Date or subsequently acquired, if, immediately after giving effect to the incurrence of such Debt
and the application of the proceeds from such Debt on a pro forma basis, the aggregate principal amount (determined on a consolidated basis in accordance with GAAP) of all outstanding Debt of the Company and its Subsidiaries which is secured by a
Lien on any property or assets of the Company or any of its Subsidiaries is greater than 40% of the sum of (without duplication): 


  

	 	(A)	 the Total Assets of the Company and its Subsidiaries as of the last day of the then most recently ended fiscal
quarter covered in AAT’s annual or quarterly report most recently furnished to Holders of the Securities or filed with the Commission, as the case may be; and

	 	(B)	 the aggregate purchase price of any real estate assets or mortgages receivable acquired, and the aggregate
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 fiscal
quarter, including the proceeds obtained from the incurrence of such additional Debt. 


  

	 	(ii)	 For purposes of this covenant, Debt will be deemed to be incurred by the Company or any of its Subsidiaries
whenever the Company or such Subsidiary shall create, assume, guarantee or otherwise become liable in respect thereof. 


  

	 	(d)	 Maintenance of Total Unencumbered Assets. The Company will not have at any time Total Unencumbered Assets of
less than 150% of the aggregate principal amount of all outstanding Unsecured Debt of the Company and its Subsidiaries determined on a consolidated basis in accordance with GAAP. For purposes of this covenant, Debt will be deemed to be incurred by
the Company or any of its Subsidiaries whenever the Company or such Subsidiary shall create, assume, guarantee or otherwise become liable in respect thereof. 


  


	 	(e)	 Future Guarantors. 


  

	 	(i)	 If at any time after the issuance of the Securities, including following any release of any Subsidiary that
guarantees the Securities pursuant to the covenant described in this paragraph (such Subsidiary, a “Subsidiary Guarantor”) from its guarantee under the Indenture (a “Subsidiary Guarantee”), a Subsidiary of the
Company (including any future Subsidiary) guarantees Unsecured Debt of the Company (that would constitute Debt under letter (a) of the definition thereof) in an amount equal to or greater than $5.0 million, AAT will cause such Subsidiary
to guarantee the Securities by executing and delivering a supplemental indenture in accordance with the Indenture within 10 business days; provided that if the other Unsecured Debt of the Company being guaranteed by such Subsidiary that gives rise
to the obligation of such Subsidiary Guarantor to guarantee the Securities pursuant to the covenant described in this paragraph is Acquired Debt, AAT will cause such Subsidiary to guarantee the Securities by executing and delivering a supplemental
indenture in accordance with the Indenture within 30 days. 


  

	 	(ii)	 For so long as (A) the Securities are rated at least BBB+, Baa1 or the equivalent, provided, that if such
rating is equal to BBB+, Baa1 or the equivalent it must be without qualification by a negative outlook, negative watch or any other similar indication of potential downgrade (an “Applicable Rating”), by at least two of S&P,
Moody’s and Fitch (or, if any of S&P, Moody’s or Fitch have been replaced in accordance with the definition of “Rating Agencies,” by at least two of the then-applicable Rating Agencies) and (B) no default has occurred
and is continuing under the Indenture, the Company, AAT, and the Subsidiaries will not be subject to the covenant described above in Section 16(e)(i) (the “Suspended Covenant”). 



 

	 	(iii)	 If at any time the Securities are no longer assigned an Applicable Rating by at least two of S&P,
Moody’s and Fitch (or, if any of S&P, Moody’s or Fitch have been replaced in accordance with the definition of “Rating Agencies,” by at least two of the then-applicable Rating Agencies), then the Suspended Covenant
will thereafter be reinstated (the “Reinstatement Date”) and will be applicable 



  
 I-7 














	 	
pursuant to the terms of the Indenture (including in connection with performing any calculation or assessment to determine compliance with the terms of the indenture) and, in the event that any
Subsidiaries would be required to guarantee the Securities at the time of such reinstatement, the Subsidiary Guarantee of such Subsidiary shall be automatically reinstated on (or, if any such Subsidiary was not a Subsidiary Guarantor of the
Securities at the time of the suspension, such entity shall enter into a supplemental indenture pursuant to which it shall become a Subsidiary Guarantor of the Securities under the Indenture within 10 business days of) such Reinstatement Date and,
unless and until the Securities subsequently attain an Applicable Rating from at least two of S&P, Moody’s and Fitch (or, if any of S&P, Moody’s or Fitch have been replaced in accordance with the definition of “Rating
Agencies,” by at least two of the then applicable Rating Agencies) and no default shall have occurred and be continuing (in which event the Suspended Covenant and the Subsidiary Guarantees will no longer be in effect for such time that the
Securities maintain an Applicable Rating from two or more Rating Agencies, subject to subsequent reinstatement thereof under the circumstances described above in this paragraph). The period of time from and including the date of suspension of the
Suspended Covenant to, but excluding, the Reinstatement Date or, if there is no Reinstatement Date, through and including the final maturity date of the Securities is referred to as a “Suspension Period.” For purposes of clarity, it is
understood that there may be one or more Suspension Periods and one or more Reinstatement Dates. The Company shall provide an Officers’ Certificate to the Trustee indicating the occurrence of any Suspension Period, Suspended Covenant or
Reinstatement Date. The Trustee shall have no obligation to monitor the ratings of the Securities, independently determine or verify if such events have occurred or notify the Holders of the Securities of any Suspension Period, Suspended Covenant or
Reinstatement Date. 

  

	 	(iv)	 The obligations of any Subsidiary Guarantor under such a Subsidiary Guarantee will be limited to the amount
necessary to prevent such guarantee from constituting a fraudulent transfer or conveyance under applicable law. Any Subsidiary Guarantee will be a continuing guarantee and will inure to the benefit of and be enforceable by the Trustee, the Holders
of the Securities and their successors, transferees and assigns. 


  

	(17)	 Section 402 of the Indenture shall apply to the Securities of such series, provided that (i) the
Company may effect legal defeasance (as defined in the Indenture) and covenant defeasance (as defined in the Indenture) pursuant to Section 402 only with respect to all (and not less than all) of the Outstanding Securities of such series and
(ii) in addition to the covenants specifically referred to by section number in Section 402(3) of the Indenture, the Additional Covenants shall also be subject to covenant defeasance pursuant to Section 402(3) of the Indenture;
provided that, anything herein to the contrary notwithstanding, the only portions of Section 1004 of the Indenture that shall be subject to covenant defeasance are the portions expressly identified in Section 402(3) of the Indenture as
being subject to covenant defeasance.
