Section 2.6      Limitations on Incurrence of Debt.

(a)      Limitation on Total Outstanding Debt . The Issuer 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 of the Issuer’s and its Subsidiaries’ outstanding Debt (determined on a consolidated basis in accordance with United States generally accepted accounting principles) is greater than 60% of the sum of the following (without duplication): (1) the Issuer’s and its Subsidiaries’ Total Assets as of the last day of the then most recently ended fiscal quarter and (2) 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 Issuer or any Subsidiary of the Issuer since the end of such fiscal quarter, including the proceeds obtained from the incurrence of such additional Debt.

(b)      Limitation on Secured Debt . The Issuer 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 of the Issuer’s or any of its Subsidiaries’ property or assets, whether owned on the date of this First Supplemental Indenture 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 of all of the Issuer’s and its Subsidiaries’ outstanding Debt (determined on a consolidated basis in accordance with United States generally accepted accounting principles) which is secured by a Lien on any of the Issuer’s or its Subsidiaries’ property or assets is greater than 40% of the sum of (without duplication): (1) the Issuer’s and its Subsidiaries’ Total Assets as of the last day of the then most recently ended fiscal quarter; and (2) 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 Issuer or any of its Subsidiaries since the end of such fiscal quarter, including the proceeds obtained from the incurrence of such additional Debt.

(c)      Debt Service Test .

   (1)      The Issuer 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 most recently ended 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 United States generally accepted accounting principles), and calculated on the following assumptions:

     (A)      such Debt and any other Debt (including, without limitation, Acquired Debt) incurred by the Issuer 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 Issuer 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 Issuer 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.

   (2)      If the Debt giving rise to the need to make the calculation described in Section 2.6(c)(1)  hereof 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 Section 2.6(c) hereof, Debt will be deemed to be incurred by the Issuer or any of its Subsidiaries whenever the Issuer or any of its Subsidiaries shall create, assume, guarantee (on a non-contingent basis) or otherwise become liable in respect thereof.

(d)      Maintenance of Total Unencumbered Assets . The Issuer and its Subsidiaries will not have at any time Total Unencumbered Assets of less than 150% of the aggregate principal amount of all of the Issuer’s and its Subsidiaries’ outstanding Unsecured Debt determined on a consolidated basis in accordance with United States generally accepted accounting principles.

Section 2.7      Insurance.

The Issuer will, and will cause of each of its Subsidiaries to, keep in force upon all of the Issuer’s and each of its Subsidiaries’ properties and operations insurance policies carried with responsible insurance companies in such amounts and covering all such risks as is customary in the industry in which the Issuer and its Subsidiaries do businesses in accordance with prevailing market conditions and availability.

Section 2.8      Maintenance of Properties.

The Issuer will cause all of its and its Subsidiaries’ properties used or useful in the conduct of the business of the Issuer or any of its Subsidiaries to be maintained and kept in good condition, repair and working order and supplied with all necessary equipment and the Issuer will cause all necessary repairs, renewals, replacements, betterments and improvements to be made, all as in the Issuer’s judgment may be necessary in order for the Issuer to at all times properly and advantageously conduct its business carried on in connection with such properties.

Section 2.9      Payment of Taxes and Other Claims.

The Issuer will pay or discharge or cause to be paid or discharged before it becomes delinquent: (i) all taxes, assessments and governmental charges levied or imposed on the Issuer or any of its Subsidiaries or on its or any such Subsidiary’s income, profits or property; and (ii) all lawful claims for labor, materials and supplies that, if unpaid, might by law become a Lien upon its property or the property of any of its Subsidiaries; provided , however , that the Issuer will not be required to pay or discharge or cause to be paid or discharged any tax, assessment, charge or claim the amount, applicability or validity of which is being contested in good faith.

Section 2.10     Optional Redemption.

(a)      The Issuer shall have the right to redeem the Notes at its option and in its sole discretion at any time or from time to time prior to the Maturity Date, in whole or in part. The redemption price (“ Redemption Price ”) will equal the greater of (i) 100% of the principal amount of the Notes to be redeemed or (ii) as determined by the Quotation Agent, the sum of the present values of the remaining scheduled payments of principal and interest thereon (not including any portion of such payments of interest accrued as of the Redemption Date) discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate plus 30 basis points (0.30% or thirtyone-hundredths of one percent), plus, in each case, accrued and unpaid interest thereon to the applicable Redemption Date; provided , however , that if the Redemption Date falls after a Record Date and on or prior to the corresponding interest payment date, the Issuer will pay the full amount of accrued and unpaid interest, if any, on such interest payment date to the Holder of record at the close of business on the corresponding Record Date (instead of the Holder surrendering its Notes for redemption). Notwithstanding the foregoing, if the Notes are redeemed on or after March 15, 2024, the Redemption Price will be equal to 100% of the principal amount of the Notes being redeemed plus unpaid interest, if any, accrued thereon to, but excluding, the Redemption Date.

(b)      The Issuer shall not redeem the Notes pursuant to Section 2.10(a)  hereof on any date if the principal amount of the Notes has been accelerated, and such an acceleration has not been rescinded or cured on or prior to such date (except in the case of an acceleration resulting from a default by the Issuer in the payment of the Redemption Price with respect to the Notes to be redeemed).

Section 2.11     Execution and Delivery of Guarantee.

The Guarantee substantially in the form of Exhibit B supplemental hereto shall be endorsed on each Security authenticated and delivered by the Trustee under Section 15.02 of the Base Indenture. The delivery of any such Security by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Guarantee set forth in the Indenture on behalf of the Guarantor.
