                   -----------------
          annual rent (the "Basic Annual Rent") at such place as Landlord may
          designate, without prior demand therefore and without any deduction
          or set off whatsoever, the sum of One Million Nine Hundred Fifty-
          Seven Thousand Four Hundred Fifty-Four and 10/100 Dollars
          ($1,957,454.10) per year.  Said Basic Annual Rent shall be due and
          payable in twelve (12) equal monthly installments to be paid in
          advance on or before the first day of each calendar month during the
          term of the Lease.  The Basic Annual Rent shall escalate at the
          beginning of the second (2nd) lease year and the beginning of each
          lease year thereafter using a three percent (3%) annually compounded
          rate.  In the event the Commencement Date occurs on a day other than
          the first day of a calendar month, then Basic Annual Rent shall be
          paid on the Commencement Date for the initial fractional calendar
          month, prorated on a per-diem basis (based upon a thirty (30) day
          month).

          for the calendar year in which the Lease commences are $491,952.75
          excluding the costs of electricity and ventilation/air conditioning
          to the Buildings, and are not included in the Basic Annual Rent.  The
          Estimated Costs are based on 103,569 rentable square feet and a $4.75
          per rentable square foot cost.  If the Estimated Costs as of the date
          Tenant takes occupancy area greater than Estimated Costs at the time
          this Lease is executed, the Estimated Costs shall be increased to
          equal the Estimated Costs as of the date of Tenant's occupancy.

     12.  In the event of any inconsistency between the terms of this Amendment
          and the new substituted Exhibits or modified Exhibits attached to this
          Amendment and the Lease and its original Exhibits, the provisions of
          this Amendment and the new or amended Exhibits shall control.  Except
          as modified by or inconsistent with this Amendment and the new
          Exhibits attached to this Amendment, the provisions of the Lease and
          the Exhibits attached to the Lease shall continue in full force and
          effect.

                       CONSTRUCTION AND/OR FINISHING OF
                        IMPROVEMENTS TO LEASED PREMISES

1.   Section III(E) of Exhibit "C" is hereby modified in its entirety to read as
follows:

     E.  PAYMENT. Landlord shall furnish, construct, and complete all of the
matters entering into Landlord's Construction Obligation at its own cost and
expense. Landlord, as Tenant's agent, shall furnish, construct and complete all
of the matters constituting Tenant's Leasehold Improvement Request at the sole
cost and expense of Tenant, to be paid from the funds held by the Escrow Agent
pursuant to Section 1 of this Section III(E), or by Tenant. All fees of Tenant's
architect or engineer shall be paid by Tenant.

         1.  Subject to the last sentence of this Section 1, all expenses
     arising by reason of Tenant's Leasehold Improvement Request shall be borne
     exclusively by the Tenant. Tenant has deposited into an escrow account with
     Legacy Land Title Company (the "Escrow Agent") the sum of Two Million Five
     Hundred Twenty Nine Thousand Dollars ($2,529,000.00) for a portion of the
     cost of Tenant's Leasehold Improvement Request. Pursuant to Section 4 of
     the First Amendment to Lease Agreement to which this Exhibit "C-1" is
     attached, $457,610.00 of the amount held by the Escrow Agent shall be
     released and paid to Landlord as consideration for the execution of the
     First Amendment to Lease Agreement. The balance of the funds held by the
     Escrow Agent, $2,071,380.00 plus accrued interest, shall be held by Escrow
     Agent to satisfy Tenant's obligation to pay for Tenant Improvements.

         2.  Subject to the last sentence of this Section 2, Tenant shall pay or
     cause the Escrow Agent to pay to Landlord from the escrow account and all
     costs related to Tenant Improvements monthly as costs for Tenant
     Improvements are incurred. Landlord shall provide Tenant with an
     anticipated schedule of monthly draw amounts. To the extent that at any
     time the cost of Tenant's Leasehold Improvement Request, as modified
     pursuant to the next sentence, is less than the sum of the Tenant Allowance
     plus amounts disbursed from escrow to pay the cost of Tenant's Leasehold
     Improvement Request, the balance shall immediately be returned to Tenant.
     Tenant may reduce the cost or scope of Tenant's Leasehold Improvement
     Request with the consent of Landlord, which consent shall not be withheld
     if the Tenant's Improvements comply with applicable law and reasonable
     engineering and design practices for a Class "A" office building, but any
     reduction shall not affect Tenant's obligation to open for business in the
     Leased Premises or to pay Basic Annual Rent, Additional Rent or other rents
     and charges under the Lease Agreement as modified by the First Amendment to
     Lease. If, however, Tenant defaults in performing any of its obligations
     under the Lease prior to full disbursement of the

                                      C-1

escrow account, Landlord shall have a security interest in any amounts remaining
in escrow to secure payment of any damages finally determined to be owing by
Tenant. Except to the extent more extensive Tenant Improvement are approved by
Tenant, Tenant shall not be responsible to pay more than Two Million Seventy-One
Thousand Three Hundred Eighty and no/100 Dollars ($2,071,380.00) for its Tenant
Leasehold Improvement Request and Landlord shall not be obligated to pay any
amount for Tenant Improvements. In no event shall Tenant be obligated to pay any
amount of cost overruns for items other than Tenant Leasehold Improvement
Requests.

     3.  In the event of any inconsistency between Exhibit "C-1" and Exhibit "C"
the provisions of this Exhibit "C-1" shall control. Except as modified by this
Exhibit "C-1", Exhibit "C" is hereby ratified and affirmed.
