ARTICLE 3

ADDITIONAL COVENANTS


Section 3.1Additional Covenants of the Company.  In addition to the covenants of the Company set forth in Article Eight and Article Ten of the Base Indenture, the Holders of the Notes shall have the benefit of the following covenants:
(a)Limitations on Incurrence of Debt.
(i)The Company will not, and will not permit any Subsidiary to, incur any additional Debt if, immediately after giving effect to the incurrence of such additional Debt and the application of the proceeds therefrom, the aggregate principal amount of all outstanding Debt of the Company and its Subsidiaries on a consolidated basis determined in accordance with GAAP is greater than 60% of the sum of (without duplication):
(A)Total Assets as of the end of the fiscal quarter covered by the Company’s Annual Report on Form 10-K or Quarterly Report on Form 10-Q, as the case may be, most recently filed with the Commission (or, if such filing is not permitted or required under the Exchange Act, with the Trustee) (such quarter, the “Latest Completed Fiscal Quarter”) prior to the incurrence of such additional Debt; and
(B)the purchase price of any real estate assets or mortgages receivable acquired, and the amount of any securities offering proceeds received (to the extent that such proceeds were not used to acquire real estate assets or mortgages receivable or used to reduce Debt), by the Company or any Subsidiary since the end of such Latest Completed Fiscal Quarter, including those proceeds obtained in connection with the incurrence of such additional Debt.
For purposes of this Supplemental Indenture, the sum of (A) and (B) above is the Company’s “Adjusted Total Assets.”
(ii)The Company will not, and will not permit any Subsidiary to, incur any additional Secured Debt if, immediately after giving effect to the incurrence of such additional Secured Debt and the application of the proceeds therefrom, the aggregate principal amount of all outstanding Secured Debt of the Company and its Subsidiaries on a consolidated basis determined in accordance with GAAP is greater than 40% of Adjusted Total Assets.
(iii)The Company will not, and will not permit any Subsidiary to, incur any additional Debt if, immediately after giving effect to the incurrence of such additional Debt and on a pro forma basis, including the application of the proceeds therefrom, the ratio of Consolidated Income Available for Debt Service to Annual Debt Service 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 1.0, and calculated on the assumptions that:
(A)such Debt and any other Debt incurred by the Company and its Subsidiaries on a consolidated basis since the first day of such four-quarter period and the application of the proceeds therefrom, including to refinance other Debt, had occurred at the beginning of such period;
(B)the repayment, retirement or other discharge of any other Debt by the Company and its Subsidiaries on a consolidated basis since the first day of such four-quarter period had occurred at the beginning of such period (except that, in making such computation, the amount of Debt under any revolving credit facility shall be computed based upon the average daily balance of such Debt during such period);
(C)in the case of Acquired Debt or Debt incurred in connection with or in contemplation of any acquisition, including any Person becoming a Subsidiary, since the first day of such 
7








four-quarter period, the related acquisition had occurred as of the first day of such period with appropriate adjustments with respect to such acquisition being included in such pro forma calculation; and
(D)in the case of any acquisition or disposition by the Company and its Subsidiaries on a consolidated basis of any asset or group of assets since the first day of such four-quarter period, whether by merger, stock purchase or sale, or asset purchase or sale, such acquisition or disposition or any related repayment of Debt had occurred as of the first day of such period with the appropriate adjustments with respect to such acquisition 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 interest rate, then, for purposes of calculating the Annual Debt Service, the interest rate on such Debt will be computed on a pro forma basis as if the average interest rate which would have been in effect during the entirety of such four-quarter period had been the applicable rate for the entirety of such period.
(b)Maintenance of Total Unencumbered Assets.  The Company and its Subsidiaries will at all times maintain Total Unencumbered Assets of not less than 150% of the aggregate outstanding principal amount of the Unsecured Debt of the Company and its Subsidiaries on a consolidated basis in accordance with GAAP.

Section 4.6Additional Events of Default.  In accordance with Section 501(g) of the Base Indenture, the following shall also constitute an “Event of Default” with respect to the Notes:
“(1)    a default under any bond, debenture, note or other evidence of indebtedness of the Company, or under any mortgage, indenture or other instrument of the Company (including a default with respect to Securities issued under the Indenture other than the Notes) under which there may be issued or by which there may be secured any indebtedness of the Company (or by any Subsidiary, the repayment of which the Company has guaranteed or for which the Company is directly responsible or liable as obligor or guarantor), whether such indebtedness now exists or shall hereafter be created, which default shall constitute a failure to pay an aggregate principal amount exceeding $25,000,000 of such indebtedness when due and payable after the expiration of any applicable grace period with respect thereto and shall have resulted in such indebtedness in an aggregate principal amount exceeding $25,000,000 becoming or being declared due and payable prior to the date on which it would otherwise have become due and payable; provided, however, that if there is no other senior unsecured indebtedness of the Company, the maturity of which would be accelerated by a default under any of the Company’s indebtedness in an aggregate principal amount of $25,000,000 or less, the references to $25,000,000 in this clause (c) shall be replaced by the lesser of the indebtedness cross-default amount contained in the Company’s then existing senior unsecured credit facility or such other senior unsecured indebtedness, as long as such amount is greater than $25,000,000, not to exceed $50,000,000.  Such default shall not be an Event of Default if the indebtedness shall have been discharged, or such acceleration shall have been rescinded or annulled, within a period of ten (10) days after there shall have been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of more than 25% in aggregate principal amount of the Outstanding Notes a written notice specifying such default and requiring the Company to cause such indebtedness to be discharged or cause such acceleration to be rescinded or annulled and stating that such notice is a “Notice of Default” under the Indenture;”
Section 4.7Amounts due on Acceleration.  Notwithstanding any provisions to the contrary in the Base Indenture, upon any acceleration of the Notes under Section 502 of the Base Indenture, the amount immediately due and payable in respect of the Notes shall equal the outstanding principal amount thereof, plus accrued and unpaid interest thereon.
Section 4.8Applicability of Satisfaction and Discharge.  Article Four of the Base Indenture applies to the Notes, except for the proviso at the end of Section 401(a).
Section 4.9Applicability of Defeasance and Covenant Defeasance.  Article Thirteen of the Base Indenture applies to the Notes, except for the proviso in the first sentence of Section 1304(a).

[Form of Reverse of Security]


1.    General.  This Security is one of a duly authorized issue of securities of the Company (the “Securities”),  issued and to be issued in one or more series under an Indenture, dated as of July 20, 2017 (the “Base Indenture”), between the Company and U.S. Bank National Association (the “Trustee”, which term includes any successor trustee under the Base Indenture), as supplemented by a Fifth Supplemental Indenture, dated as of September 28, 2021 (as amended, supplemented or otherwise modified from time to time, the “Supplemental Indenture” and the Base Indenture, as supplemented by such Supplemental Indenture, the “Indenture”), between the Company and the Trustee, and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee, and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered.  This Security is one of the series designated on the face hereof (such series, the “Notes”).
2.    Optional Redemption.  The Notes will be subject to redemption in whole at any time or in part from time to time prior to their maturity at the option of the Company upon not less than fifteen (15) nor more than sixty (60) days’ notice to each Holder of Notes to be redeemed at its address appearing in the Security Register, or, in the case of any Note that is a Global Security, in accordance with the procedures of the Depositary and its participants in effect from time to time, at a Redemption Price equal to the sum of (i) the principal amount of the Notes being redeemed, plus accrued and unpaid interest, if any, to, but not including, the applicable Redemption Date and (ii) the Make-Whole Amount, if any (it being understood that if the Notes are redeemed on or after July 15, 2031, the Make-Whole Amount equals zero).  
As used herein, the term “Make-Whole Amount” means the excess, if any, of (i) the aggregate present value as of the date of redemption of each dollar of principal being redeemed and the amount of interest (exclusive of interest accrued to the date of redemption) that would have been payable in respect of such dollar if such redemption had been made on July 15, 2031, determined by discounting, on a semi-annual basis, such principal and interest at the Reinvestment Rate (determined on the third Business Day preceding the date such notice of redemption is given) from the date on which such principal and interest would have been payable if such redemption had been made on July 15, 2031 over (ii) the aggregate principal amount of the notes being redeemed. In the case of any redemption of  the notes on or after July 15, 2031, the Make-Whole Amount will equal zero. The Make-Whole Amount shall be calculated by the Company and set forth in an Officer’s Certificate delivered to the Trustee, and the Trustee shall be entitled to rely on said Officer’s Certificate.
As used herein, the term “Reinvestment Rate” means a rate per annum equal to the sum of 0.350% (thirty five one hundredths of one percent), plus the yield on treasury securities at constant maturity under the heading “Week Ending” published in the Statistical Release under the caption “Treasury Constant Maturities” for the maturity (rounded to the nearest month) corresponding to the remaining life to maturity of the notes (which shall be deemed to be July 15, 2031) as of the payment date of the principal being redeemed. If no maturity exactly corresponds to such maturity, yields for the two published maturities most closely corresponding to such maturity shall be calculated pursuant to the immediately preceding sentence and the Reinvestment Rate shall be interpolated or extrapolated from such yields on a straight-line basis, rounding in each of such relevant periods to the nearest month. For purposes of calculating the Reinvestment Rate, the most recent Statistical Release published prior to the date of determination of the Make-Whole Amount shall be used.
As used herein, the term “Statistical Release” means the statistical release designated “H.15” or any successor publication which is published daily by the Federal Reserve System and which establishes yields on actively traded United States government securities adjusted to constant maturities or, if such statistical release (or any successor publication) is not published at the time of any determination under the Indenture, then any publicly available source of similar market data used for this purpose in accordance with customary market practice which shall be designated by the Company.
The Company shall not be required to make sinking fund or redemption payments with respect to the Notes.
In the event of redemption of this Security in part only, a new Note or Notes and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.
A-3








3.    Discharge and Defeasance.  The Indenture contains provisions for discharge or defeasance at any time of the entire indebtedness of this Security or certain restrictive covenants and Events of Default with respect to this Security, in each case upon compliance with certain conditions set forth in the Indenture.
4.    Defaults and Remedies.  If an Event of Default with respect to the Notes shall occur and be continuing, the principal of the Notes, plus accrued and unpaid interest thereon, may be declared due and payable in the manner and with the effect provided in the Indenture.
5.    Actions of Holders.  The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of the Securities at the time Outstanding of each series to be affected.  The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange therefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or this Security or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Notes, the Holders of not less than a majority in principal amount of the Notes at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee shall not have received from the Holders of a majority in principal amount of Notes at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for sixty (60) days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.
6.    Payments Not Impaired.  No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.
7.    Denominations, Transfer, Exchange.  As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of and any premium and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Notes and of like tenor, 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 denominations of $2,000 and integral multiples of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Notes are exchangeable for a like aggregate principal amount of Notes and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.
No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.
8.    Persons Deemed Owners.  Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.
