What is a Supplemental Lease?
A supplemental lease is a type of agreement that is typically used when an original lease agreement has been violated in some way. This could be due to the tenant damaging the property or not paying rent on time. The lease is most commonly used to impose new terms and conditions that mitigate risk for landlords.
For example, in many cases, a supplemental lease will require the tenant to pay additional fees or fines. It may also give the landlord the right to evict the tenant if they fail to comply with the terms of the supplemental lease.
Supplemental Lease Sample
| 1. | The Lease and Amendments as last amended by Lease Extension and Modification Agreement II are hereby reinstated in full. | ||
| 2. | The term of the Lease shall commence on September 1, 2011 and expire on March 31, 2014. | ||
| 3. | The Net Usable Square Feet shall be 20,000 Net Usable Square Feet. | ||
| 4. | Landlord acknowledges receipt of the rent due September 1, 2011 in the amount of $5,000. | ||
| 5. | Commencing with the rental payment due October 1, 2011 and continuing through and including March 31, 2012, the Base Rent shall be $72,000 per year, payable in equal monthly installments of $6,000 each on the 1st day of each and every month throughout the term aforesaid, that is October 1, 2011 through March 1, 2012. | ||
| 6. | Tenant in addition to the Base Rent, shall make a single payment to Landlord during the 1st week of October, 2011 in the amount of $18,432.75. This payment is in full and final satisfaction of the obligation to pay such amount under the provisions of paragraph 5 of the Sixth Amendment to the Lease. | ||
| 7. | Tenant shall have a single option to terminate this Lease exercisable only during the month of March, 2012, only in the event Tenant does not receive either a Department of Energy grant of $1,000,000 or greater for which Tenant has already applied, or a Department of Defense Contract of $1,000,000 or greater as to which the Tenant has submitted a bid. Tenant agrees to use its best efforts in order to obtain either or both of the Department of Energy grant and the Department of Defense contract. | ||
| 8. | In the event the Tenant terminates this Lease as provided herein during the month of March, 2012, then in such event Tenant’s sole rental obligation to Landlord for Base Rent and Additional Rent during the period of this Lease from September 1, 2011 through March 31, 2012, shall be the rental obligations provided for during those periods of time set forth in paragraphs 5 and 6 above. Other than the rental obligation, Tenant shall continue to abide by and be obligated to perform all of the other terms and provisions of the Lease. | ||
| 9. | In the event the Tenant is awarded either the Department of Energy grant already applied for or the Department of Defense Contract already bid upon, each as described in Section 7 above, then in such event, commencing on the 1st day of the month immediately following the date Tenant receives formal notification of the receipt of such grant or contract, the Base Rent shall be increased from $6,000 per month to $17,500 per month, plus the Tenant’s proportionate share of taxes, insurance and other building operating expenses as set forth in the original Lease, making Tenant’s total amount due $23,451.57 per month.
