      the GC to Tenant pursuant to the construction contract between the GC and
      Tenant (the "Construction Contract") to Landlord and no such notice shall

      been received by Landlord.

                  (B) Tenant and the GC acknowledge that the GC shall have no
      lien rights against Landlord's interest in the Demised Premises or any
      part thereof.

                  (C) Nothing contained herein shall in any event or under any

      Landlord of any of the obligations or liabilities of Tenant under the
      Construction Contract.

Tenant shall provide Landlord with signed copies of the Construction Contract
and an instrument evidencing the GC's agreement to the foregoing conditions.

         (c) (i) Landlord shall pay the cost of the Initial Alterations up to
the cost of Twenty Five Dollars ($25.00) per rentable square foot (hereinafter
referred to as the "Tenant Allowance"). The Tenant Allowance shall initially be

respect to which Effective Date III has occurred, the Tenant Allowance with
respect to the next Floor(s) being renovated shall be increased by such amount
not so utilized and any portion of the Tenant Allowance not initially utilized
for the cost of the Initial Alterations to Additional Premises III may, after
the completion of Additional Premises III, be utilized by Tenant for alterations
to other portions of the Premises, and provided, further, that to the extent the
entire Tenant Allowance is not so utilized during the Term, Landlord shall
retain the same.

                  (ii) The Tenant Allowance with respect to each Floor shall be
due and payable from Landlord to Tenant as follows: one-half (l/2) shall be paid
to Tenant within ten (10) days after Tenant has completed one-half (l/2) of the

least one-half (l/2) of the Initial Alterations to such Floor have been

and any roof penetrations shall be made by Landlord's roofing contractor, at
Tenant's expense. The functional characteristics, size, design, load and method

any sort whatsoever arising by reason of the installation, maintenance,

      6. Section 21.02 of the Lease shall be deleted and the following shall be
substituted therefor:

            (a) Tenant shall have the right, at its sole cost and expense, to
      install four (4) signs on the upper exterior of the Building, and
      identification signage at ground level and in the Building lobby. The
      size, design, and location of each such sign shall be subject to
      Landlord's approval and the approval of all governmental entities having
      jurisdiction. Landlord hereby approves the design, size and location of
      such signs as shown on Exhibit "C" hereto. Tenant shall install, operate

      Building resulting therefrom, all at Tenant's sole cost and expense.

            (b) During the Term, the Building shall be named "FreeMarkets
      Center," provided that Landlord reserves the right to change the street
      address of the Building without creating or incurring any liability to
      Tenant. Tenant acknowledges that the change of the name of the Building to
      "Freemarkets Center" will require Landlord to incur costs to replace
      marketing materials and Tenant shall reimburse Landlord the cost thereof
      within (30) days after the presentation of invoices therefor, but not to
      exceed the sum of Twenty Thousand Dollars ($20,000).

      7. Section 35.17 of the Lease shall be deleted and the following shall be
substituted therefor:

      Tenant shall be entitled to five (5) parking spaces in Landlord's parking

      III and premises added to the Premises pursuant to Article 37 hereof shall
      become part of the Premises hereunder, such additional parking shall be
      provided to Tenant at the rates provided below. Four (4) of such parking
      spaces shall be designed as reserved for Tenant's exclusive use (and the
      remaining spaces shall not be reserved); provided, however, that Landlord
      shall not be responsible for policing Tenant's right to exclusively use
      such reserved parking spaces and shall have no responsibility to Tenant if
      the same are not available through acts or omissions of others unless
      Landlord has caused or permitted such acts. The monthly rate for such
      parking spaces shall be at market rates for parking spaces in the
      Building.

      8. (a) Sections 37.02 and 37.03 shall be deleted from the Lease.

         (b) The following shall be inserted as Section 37.02 of the Lease:

      Section 37.02 Right to Lease Additional Premises.

            (a) Provided Tenant is not in default after delivery of notice and
      beyond the expiration of applicable cure periods at the time of the
      exercise of such right, if Landlord receives an acceptable offer to
      initially lease any premises in the Building located on Floors 12, 14, 15,
      16, 17, 18 and/or 19, during the initial Term, Landlord shall notify
      Tenant of such

                                        5

<PAGE>

      offer in writing and Tenant shall have the right to lease such premises
      under the terms of this Section 37.02. Landlord's notice shall set forth
      the area constituting such premises, the location thereof and the
      anticipated delivery date therefor.

            (b) Tenant shall have ten (10) days from the date of Landlord's
      notice to Tenant to advise Landlord in writing that Tenant exercises its
      right to lease the same. Failure by Tenant to notify Landlord within the
      time specified shall constitute Tenant's waiver of its right to lease such
      premises and Landlord shall thereafter have the right to lease such
      premises to a third party or parties on terms and provisions acceptable to
      Landlord, in its sole discretion, for a period of six (6) months;
      provided, however, that if Landlord has not entered into a lease of such
      premises pursuant to such offer within six (6) months after such notice to
      Tenant pursuant to Section 37,02(a), Landlord shall be required to again
      offer such premises to Tenant pursuant to Section 37.02(a) prior to
      leasing the same to a third party. In the event Landlord enters into a
      lease with a third party for such premises, Tenant shall not have the
      right to lease such premises pursuant to this Section 37.02 if such
      premises again become available.

            (c) If Tenant exercises its right to so lease such premises, this
      Lease will be amended to add such premises to the Premises at the Base
      Rent and all of the other terms and provisions hereof, including a Twenty
      Five Dollar ($25.00) per square foot Tenant Allowance. Tenant shall
      renovate such premises in compliance with the provisions of this Lease.

            (d) Landlord shall renovate the restrooms for each Floor of the
      Additional Premises (but not in any other portion of the Premises) to
      comply with the ADA. Landlord shall not be required to spend in excess of
      Eighteen Thousand Dollars ($18,000.00) per Floor therefor, and any costs
      in excess of Eighteen Thousand Dollars ($18,000.00) per Floor shall be
      charged against the Tenant Allowance for such Floor. Such work shall be
      performed by Landlord in conjunction with Tenant performing the Initial
      Alterations on such Floor.

            (e) Notwithstanding anything to the contrary contained in this
      Lease, each time Tenant exercises its right to so lease any such premises
      pursuant to this Section 37.02, the initial Term shall be extended for a
      period of one-hundred and twenty (120) full calendar months from and after
      the date such premises are first deemed to be part of the Premises. In
      addition, the Base Rent shall be increased by three percent (3%) per annum
      over the rent in effect in the immediately preceding year, commencing
      January 1, 2010 and for each year thereafter that the initial Term has
      been extended as aforesaid.

            (f) Prior to the delivery of possession of each such premises
      pursuant to this Section 37.02, Landlord and Tenant shall execute an
      amendment to this Lease reflecting the addition of such premises to the
      Premises, the additional Base Rent, the change in Tenant's Share of
      Operating Expenses and Tenant's Share of Taxes, the Base Rent for the
      extended portion of the initial Term and any other revisions necessary
      because of such premises being added to the Premises.

            (g) Landlord shall not have responsibility for delays in delivering
      any such premises as a result of any occupant's failure to vacate such
      premises at the end of its lease, but Landlord shall immediately institute
      proceedings to obtain possession of such premises and this Lease with
      respect to such premises shall not commence until such premises are
      vacated and delivered to Tenant as herein provided.
