Each party further agrees to defend, indemnify and hold harmless the other party from and against any claim for commission or finder's fee by any entity who claims or alleges that they were retained or engaged by the first party or at the request of such party. 8. MUST TAKE SPACE. Tenant hereby agrees to add to the Premises approximately 1,263 additional rentable square feet of space located on the seventh (7th) floor of the Building known as Suite 725 ("MUST TAKE SPACE"), as delineated on Exhibit "A".

Any defects or deviations in, and/or disapproval by Landlord of, the Tenant Improvements shall be rectified by Tenant at no expense to Landlord, provided however, that in the event Landlord determines that a defect or deviation exists or disapproves of any matter in connection with any portion of the Tenant Improvements and such defect, deviation or matter might adversely affect the mechanical, electrical, plumbing, heating, ventilating and air conditioning or life-safety systems of the Building, the structure or exterior appearance of the Building or any other tenant's use of such other tenant's leased premises, Landlord may take such action as Landlord deems necessary, at Tenant's expense and without incurring any liability on Landlord's part, to correct any such defect, deviation and/or matter, including, without limitation, causing the cessation of performance of the construction of the Tenant Improvements until such time as the defect, deviation and/or matter is corrected to Landlord's satisfaction. 4.2.5 MEETINGS.
