Task prompt
What the agent was asked to do
2020 Main Street, Irvine (the “Premises”) needs a new HVAC System in order to accommodate INTELLIGENCE INC.'s server rooms. INTELLIGENCE INC. is a tenant at the Premises. The HVAC system will replace an old HVAC system, be much more energy efficient and reduce operating costs. MGR REAL ESTATE INC. (the "Lessor") is asking AI AUTOMATION GROUP, LLC (the "Lessee") to pay for part of the HVAC as an operating expense. Can the Lessor require the Lessee to pay for part of the new HVAC as an operating expense under the final version of the commercial lease agreement it entered into with the Lessee? Reply to me in here with a yes or no answer alongside a short explanation.
