               thereof. Either party may terminate this lease arrangement

          (c)  Webb shall be responsible for insuring its property located in
               the Premises. In no event shall Jabber have any liability to Webb
               or any occupants of the space rented by Webb, except for Jabber's
               gross negligence. In the event of any such liability, Jabber's
               liability shall be limited to the amount paid by Webb to Jabber
               pursuant to this sub-lease agreement. In no event will Jabber be
               liable pursuant to this sub-lease agreement for indirect damages,
               including, without limitation, consequential damages or lost
               profits. Webb agrees to enter into a separate sub-lease agreement
               with Jabber for the above leased space as may be required by the
               Landlord.

     2. Use of Equipment. During the term of the Lease, Webb shall make
        ----------------
available to Jabber and shall permit Jabber to use any of the equipment owned or
leased by Webb which is located in the Premises and which is currently being
used to provide the Shared Services (the "Equipment"), provided that Jabber
shall pay all out-of-pocket costs associated with maintaining such equipment
during the term of the Lease and shall provide the personnel required to service
and operate such equipment, to the same extent as Webb has provided such
maintenance and services prior to the assignment of the Lease. For any such
equipment which is rented or leased by Webb or the services for which are being
provided pursuant to agreements between the vendor and Webb, Jabber

                                      -2-

shall, to the extent it is possible to do so, be substituted for Webb and assume
its rights and obligations thereunder within a reasonable period of time
following the assignment of the Lease. Further, the use of any such equipment by
Jabber shall be in accordance with and subject to the terms of any existing
lease or other agreement for the use of the equipment.

     3. Improvements to Premises. Effective with the assignment of the Lease,
        ------------------------
Webb transfers and assigns to Jabber any and all of its right, title and
interest in the alterations, improvements and additions to the Premises.

term of the Lease, Webb shall make available to Jabber, and shall permit Jabber
to use at no cost or charge to Jabber, such pieces of the Furniture as Jabber
reasonably requires to occupy and use the Premises. Within thirty (30) days of
the assignment of the Lease, Jabber and Webb shall identify any of the Furniture
that is not now-required or expected to be required by Jabber in the future in
connection with the occupancy of the Premises (the "Excess Furniture").
Following identification of the Excess Furniture, Webb shall have the right to
remove the Excess Furniture from the Premises and to sell or dispose of the
Excess Furniture.

     5. Option to Acquire Furniture and Equipment. Upon termination of the
        -----------------------------------------
Lease, Jabber shall have the option to acquire the Furniture, including any
Excess Furniture not previously sold by Webb, and the Equipment at the lesser of
the then book value for the Furniture and Equipment as reflected in Webb's
financial statements or the then fair market value for the Furniture and
Equipment. If Webb and Jabber cannot

                                      -3-
<PAGE>

agree on the fair market value for the Furniture and Equipment, they shall
mutually select an independent appraiser to determine the fair market value for
the Furniture and Equipment. The appraiser's determination of the fair market
value for the Furniture and Equipment shall be binding on both Webb and Jabber.
Webb and Jabber shall each pay 50% of the cost of the appraisal.

     6. 2001 Operating Expenses. Webb shall promptly reimburse Jabber for any
        -----------------------
Operating Expenses (as defined in the Lease) for calendar year 2001 which Jabber
