Grading rubric

Criteria and grader verdict (showcase run)

States that the Lessee is a signatory to the revised estoppel certificate
Pass
Evidence: In /root/workspace/filesystem/Deliverables/Revised Tenant Estoppel Certificate with Analysis.docx, operative certificate recites AI Automation Group, LLC “as lessee ("Lessee")” and has signature block “TENANT / LESSEE: AI AUTOMATION GROUP, LLC.” Assessment: Criterion requires stating the Lessee is a signatory to the revised estoppel certificate; pass because the execution block identifies the signing party as Tenant/Lessee.
States that the Lessee certifies and warrants the facts listed in the revised estoppel certificate
Fail
Evidence: The operative certificate states “AI Automation Group, LLC, a California limited liability company ("Tenant" or "Lessee"), certifies to ... as follows.” I did not find language that the Lessee “warrants” the listed facts. Assessment: Criterion requires states that the Lessee “certifies and warrants” the facts; fail because the certificate includes certification language but omits the warranty component.
States that there are no options to terminate the lease early in the revised estoppel certificate
Pass
Evidence: Paragraph 10 of the operative certificate states: “Tenant has ... no express option to terminate the Lease before expiration of the applicable term, other than termination rights, if any, arising under the express remedies of the Lease or applicable law.” Assessment: Criterion requires stating there are no options to terminate the lease early; pass because this is expressly stated, with a customary remedies/legal-rights carveout.
States that the "Additional Rent" is the Lessee's proportionate share of operating expenses in the revised estoppel certificate
Pass
Evidence: Paragraph 6 states: “Tenant is obligated to pay Tenant's Proportionate Share of Operating Expenses as Additional Rent...” The preamble defines AI Automation Group as “Tenant” or “Lessee.” Assessment: Criterion requires stating Additional Rent is the Lessee's proportionate share of operating expenses; pass because the certificate states the same substantive formulation, albeit using the Tenant synonym.
Replaces each instance of "Tenant" with "Lessee" in the revised estoppel certificate
Fail
Evidence: The operative certificate repeatedly uses “Tenant,” including title “TENANT ESTOPPEL CERTIFICATE,” preamble “("Tenant" or "Lessee"),” paragraph 1 “Tenant is the lessee,” and signature block “TENANT / LESSEE.” Assessment: Criterion requires replacing each instance of “Tenant” with “Lessee”; fail because many instances of “Tenant” remain in the revised estoppel certificate.
Replaces each instance of "Landlord" with "Lessor" in the revised estoppel certificate
Pass
Evidence: In the operative revised certificate, the landlord party is referred to as “lessor ("Lessor")”; signature block is “LESSOR: MGR REAL ESTATE INC.” I found no “Landlord” usage in the operative certificate text. Assessment: Criterion requires replacing each instance of “Landlord” with “Lessor”; pass for the revised certificate because Landlord has been replaced with Lessor there.
