             (e) Landlord shall provide Tenant with an additional Tenant
         Improvement Allowance in the following amounts: (i) Thirty Dollars
         ($30) per rentable square foot with respect to the area marked on
         EXHIBIT C attached hereto; and (ii) Ten Dollars ($10) per rentable
         square foot with respect to the remainder of the available fourth floor
         premises. Said allowance shall be paid and used in accordance with
         paragraph 8 and Rider 5.C of the Lease. Tenant may use its own
         contractor and architect (both subject to Landlord's reasonable
         approval) for tenant improvement work in such premises. All costs of
         design and construction shall be included within the above allowance.

             (f) Paragraph 4 of the Lease shall apply with respect to utilities

If within ten (10) days of the date of such notice Landlord has received written
notice from Tenant of its election to lease such space on the foregoing terms
and conditions, Landlord and Tenant shall within thirty (30) days enter into a
lease amendment setting forth said terms. If Tenant fails to respond to said
notice within said ten (10) day period, or, after Tenant giving written notice
of its exercise of its right to take the space, if Landlord and Tenant do not
enter into said lease amendment within said thirty (30) day period for any
reason other than Landlord's fault, Tenant's rights under this paragraph shall
be deemed to have been waived, and Landlord shall be free to lease the space to
anyone without any further obligation to Tenant. As used herein, "third-party
tenant" excludes other parties then in possession of any portion of the premises
subject to this right of first refusal which may desire to expand its premises
or extend or renegotiate its lease or rental agreement or any other tenant in
the Building. Nothing contained herein shall require Landlord to lease to Tenant
any portion of the floor which would leave Landlord with any remaining portion
of the floor which was not commercially and economically rentable to third
parties. Should Tenant decline to take any space offered it pursuant to this
paragraph, this right of first refusal shall lapse and become void thereafter.

         12. WESTERN STAFF SERVICES SPACE. The parties acknowledge that Landlord
currently leases the premises on the third floor marked on EXHIBIT D attached
hereto (the "WSS Premises") to Western Staff Services, Inc. ("WSS") and that WSS
has the right to terminate its lease upon 270 days notice to Landlord. In the
event that WSS exercises such right and Landlord notifies Tenant in writing that
Landlord desires to lease the WSS Premises to Tenant ("Landlord's Notice"),
Tenant shall lease the WSS space from Landlord on the following terms and
conditions:

             (a) Commencing as of sixty (60) days after the date Landlord's
         lease with WSS terminates, the Premises shall include the WSS Premises.

             (j) There shall be no rental waiver or forbearance.      



             (c) Tenant's Participation for purposes of paragraph 6 shall be
         determined using the total number of rentable square feet leased by
         Tenant as the numerator. The security deposit shall be increased by an
         amount equal to $1.95 times the number of additional rentable square
         feet taken by Tenant.

             (d) Tenant shall take the space in its "as is" condition. Tenant
         shall be responsible at its expense for all demolition of and

         Improvement Allowance.

             (f) Paragraph 4 of the Lease shall apply with respect to utilities
         for such Premises.

             (g) All other terms of this Lease shall apply with respect thereto,

         Landlord and Tenant shall acknowledge in writing that the Premises
include the WSS Premises on the terms and conditions set forth above within ten
(10) days of the date of Landlord's Notice. Tenant's failure to timely execute
and deliver such acknowledgment shall constitute a default hereunder.
