Landlord and Tenant hereby stipulate and agree that the Rentable Area of the Premises shall be deemed to mean 45,629 square feet, consisting of 22,797 square feet on the second (2nd ) floor as shown on Exhibit A attached hereto (the "Second Floor Space") and 22,832 square feet on the third (3rd) floor as shown on Exhibit A-1 attached hereto.

Tenant further acknowledges that Space B may be delivered to Tenant subsequent to the delivery of the Second Floor 2 Space and Space A (together, the "Initial Space"); accordingly, the Commencement Date with respect to such spaces may occur at separate times. In the event the Commencement Date for Space B occurs subsequent to the Commencement Date for the Initial Space, the Lease Term shall be determined based upon the initial Commencement Date, it being agreed that the Lease Term for the Initial Space and Space B shall expire coterminously. The "Rentable Area of the Building" shall mean 217,500 square feet. If the Premises being leased to Tenant hereunder include one or more floors within the Building in their entirety, the definition of Premises with respect to such full floor(s) shall include all corridors and restroom facilities located on such floor(s).

Notwithstanding the foregoing, the amount of such monthly installments of Base Rental is subject to modification as follows: (i)In the event that the Commencement Date for Space B occurs after the Commencement Date for the Initial Space, Tenant shall only be required to pay Base Rental with respect the Initial Space. In such case, the monthly installment of Base Rental as of the Commencement Date would be $95,199.70 and, upon the occurrence of the Commencement Date with respect to Space B, the monthly installment of Base Rental would increase by $23,055.45 to be $118,255.15; (ii) In the event the Commencement Date does not occur on the first day of a calendar month (or in the event the Commencement Date with respect to a particular space does not occur on the first day of a calendar month), Base Rental with respect to such initial calendar month shall be appropriately prorated based upon a percentage the numerator of which is the number of days of Lease Term that fall within such calendar month and the denominator of which in the total number of days in such calendar month; 2 3 (iii) provided Tenant is not in default after the expiration of applicable cure periods, Tenant shall be entitled to receive a full abatement of Base Rental with respect to the first sixty (60) days of the Lease Term (the "Abatement Period").

COMMENCEMENT DATE. Effective as of the Effective Date, Section 1.A.4 of the Lease shall be deleted in its entirety and the following inserted in lieu thereof: "4. The "Commencement Date," "Lease Term" and "Termination Date" shall have the meanings set forth in subsection l.A.4.a. below or subsection l.A.4.b. below (delete one): a. The "Lease Term" shall mean a period of one hundred twenty (120) months commencing on the Commencement Date, provided if the Commencement Date does not occur on the first day of a calendar month, the Lease Term shall automatically be extended by the number of days in the period beginning on the Commencement Date and ending on the last day of the month in which the Commencement Date occurs. For purposes hereof, the Commencement Date shall mean (i) with respect to the Initial Space, the date on which Landlord delivers the Initial Space to Tenant free from occupancy by (x) NationsCredit Commercial Corporation ("Nations"), the existing tenant in the Second Floor Space; (y) Coopers, the existing tenant in Space A or (z) other party; and (ii) with respect to Space B, the date on which Landlord delivers Space B to Tenant free from occupancy by Coopers, the existing tenant in Space B, or any other party.

Tenant also acknowledges that Coopers is currently leasing the Third Floor Space pursuant to the terms of the Coopers Lease, which lease is currently scheduled to expire on November 17, 1998. 3 4 Furthermore, Tenant acknowledges that Space A is currently sublet by Coopers to Nations. Landlord agrees to use good faith efforts to negotiate an agreement with Coopers pursuant to which the Landlord would be able to terminate the Coopers Lease with respect to Space A before the stated expiration date thereof. In the event Landlord enters into such agreements accelerating the expiration dates of the Nations Lease and the Coopers Lease, Landlord shall provide Tenant with written notice (the "Early Commencement Notice") setting forth the date on which Landlord intends to provide Tenant with possession of the Initial Space (i.e. the targeted Commencement Date). Such Early Commencement Notice shall be delivered to Tenant not less than fifteen (15) days prior to the date on which Landlord intends to provide Tenant with possession of the Initial Space. Notwithstanding the foregoing, in no event shall the Commencement Date occur prior to May 1, 1998 without the written consent of Tenant. In addition, Tenant acknowledges that Space B is currently sublet by Coopers to Howard Systems and that Landlord shall have the right to permit Howard Systems to remain in Space B beyond the expiration of the Coopers Lease. As of the date hereto it is anticipated that Howard Systems may need to remain in Space B until December 31,1998 (i.e. the targeted Commencement Date of Space B is January 1, 1999). Landlord shall provide Tenant with written notice (the "Space B Notice") setting forth the date on which Landlord intends to provide Tenant with possession of Space B. Such Space B Notice shall be delivered to Tenant not less than ten (10) days prior to the date on which Landlord intends to provide Tenant with possession of Space B.

Notwithstanding the foregoing, if the Commencement Date with respect to the entire Premises does not occur on the same day, Tenant's Pro Rata Share shall be calculated only with respect to the portion of the Premises for which the Commencement Date has occurred. Based upon the assumption that Space B will not be delivered until after the delivery of the Initial Space, Tenant's Pro Rata Share as of the Commencement Date for the Initial Space would be 16.89%. Upon the occurrence of the Commencement Date with respect to Space B, Tenant's Pro Rata Share would increase by 4.09% to be 20.98%. 4 5 5. ALLOWANCE.
