The 1 measured square footage amounts will be incorporated into this lease by an attachment and the monthly rent expense adjusted. If Sublessee desires to vacate the 813 square feet of optional space it shall give Sublessor at least ten (10) days prior written notice. Sublessee shall also have the right to use the common areas (restrooms, elevator to garage, hallways thereto) of the Master Premises, but not those areas used by Sublessor or its personnel or invitees, and to use the docking area for shipping and receiving. Additionally, Sublessee's employees shall be permitted to use the exercise facilities at the Master Premises, if such facilities are present, at their own cost provided any employee desiring to use such facilities has been evaluated and trained before using the facilities in the same manner as Sublessor's employees and signed a release form in favor of Sublessor. Sublessor shall be able to increase the amount of rent retroactively to any period of time that it can show that Sublessee used, for any purpose including storage of materials, more space than it notified Sublessor that it was using ("Unauthorized Usage"). Rent for the Unauthorized Usage shall be twice the rental per foot set forth herein. 5. PARKING. Sublessee shall be entitled to that number of parking spaces according to the following formula rounded down to the nearest whole number: Square footage leased by Sublessee x 278 = Number of parking spaces ---------------------------------- 72,000 For example, in the first month of this Sublease, Sublessee shall be entitled to a total of 55 parking spaces calculated as follows: 14,334 x 278 = 55 ------ 72,000 Sublessee shall be entitled to have one underground parking space per thousand square feet of their rented premises, rounded down to the nearest whole number.

The term of this Sublease shall commence on January 1, 1997 ("Commencement Date") and end of December 31, 1999 ("Termination Date"), unless otherwise sooner terminated in accordance with the provisions of this Sublease.
