         appropriately amended and Landlord is willing to do the same on the
         following terms and conditions.

         NOW, THEREFORE, in consideration of the mutual covenants and agreements
herein contained and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, Landlord and Tenant agree as
follows:

I.       Suite 220 Expansion and Effective Date. Effective as of the Suite 220
         --------------------------------------
         Expansion Effective Date (defined below), the Premises, as defined in
         the Lease, is increased by the addition of the Suite 220 Expansion
         Space, and from and after the Suite 220 Expansion Effective Date, the
         Suite 220 Expansion Space, shall be deemed to be part of the Premises,
         as defined in the Lease. The term for the Suite 220 Expansion Space
         shall commence on the Suite 220 Expansion Effective Date and end on the
         Expiration Date. The Suite 220 Expansion Space is subject to all the
         terms and conditions of the Lease except as expressly modified herein
         and except that Tenant shall not be entitled to receive any allowances,
         abatements or other financial concessions granted with respect to the
         Original Premises unless such concessions are expressly provided for
         herein with respect to the Suite 220 Expansion Space.

         A.       The Suite 220 Expansion Effective Date shall be the date which
                  is 14 days after the date Landlord tenders possession of the
                  Suite 220 Expansion Space to Tenant. Landlord and Tenant
                  anticipate that the Suite 220 Expansion Effective Date shall
                  be April 9, 2001 be ("Suite 220 Target Expansion Effective
                  Date").

         B.       Subject to Section IX.A. below, the Suite 220 Expansion
                  Effective Date shall be delayed to the extent that Landlord
                  fails to deliver possession of the Suite 220 Expansion Space
                  for any reason, including but not limited to, holding over by
                  prior occupants. Any such delay in the Suite 220 Expansion
                  Effective Date shall not subject Landlord to any liability for
                  any loss or damage resulting therefrom. If the Suite 220
                  Expansion Effective Date is delayed, the Expiration Date shall
                  not be similarly extended.

VI.      Improvements to Suite 220 Expansion Space.
         -----------------------------------------

         A.       Condition of Suite 220 Expansion Space. Tenant has inspected
                  the Suite 220 Expansion Space and agrees to accept the same
                  "as is" without any agreements, representations,
                  understandings or obligations on the part of Landlord to
                  perform any alterations, repairs or improvements, except as
                  may be expressly provided otherwise in this Amendment and
                  Section 7 of the Lease.

         B.       Responsibility for Improvements to Suite 220 Expansion Space.
                  Provided Tenant is not in default, Landlord agrees to
                  contribute the sum of $5,340.00 (the "Allowance") toward the
                  cost of performing the construction, alterations or
                  improvements (the "Improvements") in preparation of Tenant's
                  occupancy of the Suite 220 Expansion Space. The Allowance
                  shall be paid to Tenant within 30 days following receipt by
                  Landlord of all receipted bills used in the Improvements. The
                  Allowance shall be disbursed in the amount reflected on the
                  receipted bills meeting the requirements above.
                  Notwithstanding anything herein to the contrary, Landlord
                  shall not be obligated to disburse any portion of the
                  Allowance during the continuance of an uncured default under
                  the Lease, and Landlord's obligation to disburse shall only
                  resume when and if such default is cured. Any Improvements to
                  the Suite 220 Expansion Space shall be by Commercial Interior
                  Contractors ("CIC") and shall be governed in all respects by
                  the terms set forth in Section 6 of the Lease. Tenant may
                  contract directly with CIC and may, with Landlord's reasonable
                  prior approval, select its own architect. In addition,
                  Landlord shall have the right to select and/or approve of any
                  subcontractors used in connection with the Improvements. In
                  any and all events, the Suite 220 Expansion Effective Date
                  shall not be postponed or delayed if the initial improvements
                  to the Suite 220 Expansion Space are incomplete on the Suite
                  220 Expansion Effective Date for any reason whatsoever. Any
                  delay in the completion of initial improvements to the Suite
                  220 Expansion Space shall not subject Landlord to any
                  liability for any loss or damage resulting therefrom.

VII.     Early Access to Suite 220 Expansion Space. During any period that
         -----------------------------------------
         Tenant shall be permitted to enter the Suite 220 Expansion Space prior
         to the Suite 220 Expansion Effective Date (e.g., to perform alterations
         or improvements, if any), Tenant shall comply with all terms and
         provisions of the Lease, except those provisions requiring payment of
         Base Rent or Additional Rent as to the Suite 220 Expansion Space. If
         Tenant takes possession of the Suite 220 Expansion Space prior to the
         Suite 220 Expansion Effective


                                       2



         Date for any reason whatsoever (other than the performance of work in
         the Suite 220 Expansion Space with Landlord's prior approval), such
         possession shall be subject to all the terms and conditions of the
         Lease and this Amendment, and Tenant shall pay Base Rent and Additional
         Rent as applicable to the Suite 220 Expansion Space to Landlord on a
         per diem basis for each day of occupancy prior to the Suite 220
         Expansion Effective Date.

IX.      Other Pertinent Provisions.
         --------------------------

         A.       Contingency. This Amendment is contingent upon Landlord's
                  delivery of the Suite 220 Expansion Space on or before April
                  9, 2001. If Landlord has not delivered the Suite 220 Expansion
                  Space on or before April 9, 2001, then either party may
                  terminate this Amendment with respect to the Suite 220
                  Expansion Space by providing written notice thereof to the
                  other party on or after April 9, 2001, whereupon, this
                  Amendment shall be null and void and of no force or effect and
                  the Lease shall continue in full force and effect as if this
                  Amendment had not been executed.

         B.       Parking. Effective as of the Suite 220 Expansion Effective
                  Date, and without reducing the number of parking spaces made
                  available to Tenant with respect to the Original Premises as
                  provided in the Lease, as amended, 4 additional unreserved
                  parking spaces shall be made available to Tenant for parking
                  by Tenant and its employees, free of charge, for the period
                  commencing on the Suite 220 Expansion Effective Date and
                  ending on the Expiration Date.

X.       Miscellaneous.
         -------------

         A.       This Amendment sets forth the entire agreement between the
                  parties with respect to the matters set forth herein. There
                  have been no additional oral or written representations or
                  agreements. Under no circumstances shall Tenant be entitled to
                  any Rent abatement, improvement allowance, leasehold
                  improvements, or other work to the Premises, or any similar
                  economic incentives that may have been provided Tenant in
                  connection with entering into the Lease, unless specifically
                  set forth in this Amendment.

         B.       Except as herein modified or amended, the provisions,
                  conditions and terms of the Lease shall remain unchanged and
                  in full force and effect.

         C.       In the case of any inconsistency between the provisions of the
                  Lease and this Amendment, the provisions of this Amendment
                  shall govern and control.

         D.       Submission of this Amendment by Landlord is not an offer to
                  enter into this Amendment but rather is a solicitation for
                  such an offer by Tenant. Landlord shall not be bound by this
                  Amendment until Landlord has executed and delivered the same
                  to Tenant.

         E.       The capitalized terms used in this Amendment shall have the
                  same definitions as set forth in the Lease to the extent that
                  such capitalized terms are defined therein and not redefined
                  in this Amendment.

         F.       Tenant hereby represents to Landlord that Tenant has dealt
                  with no broker other than CB Richard Ellis ("Broker") in
                  connection with this Amendment. Tenant agrees to indemnify and
                  hold Landlord, its trustees, members, principals,
                  beneficiaries, partners, officers, directors, employees,
                  mortgagee(s) and agents, and the respective principals and
                  members of any such agents (collectively, the "Landlord
                  Related Parties") harmless from all claims of any brokers
                  (other than Broker) claiming to have represented Tenant in
                  connection with this Amendment. Landlord hereby represents to
                  Tenant that Landlord has dealt with no broker in connection
                  with this Amendment. Landlord agrees to indemnify and hold
                  Tenant, its trustees, members, principals, beneficiaries,
                  partners, officers, directors, employees, and agents, and the
                  respective principals and members of any such agents
                  (collectively, the "Tenant Related Parties") harmless from all
                  claims of any brokers claiming to have represented Landlord in
                  connection with this Amendment.
