         2. Tenant Renovations. Tenant desires to renovate a portion of the
Premises and Landlord is willing to allow Tenant to do so. Tenant shall have the
right to perform the improvements indicated on Exhibit "A" attached hereto
("Second Supplemental Tenant Renovations"). Landlord must approve any material
modification to the attached plans. For the purposes of this paragraph, Second
Supplemental Tenant Renovations shall include all work in Exhibit "A" and shall
be performed in a workmanlike manner and in compliance with all state, local and
federal laws and ordinances.

         3. Tenant's Restoration of the Demised Premises. Notwithstanding
anything to the contrary contained in this Amendment, Tenant hereby covenants
and agrees that at Landlord's option Tenant shall, at its sole cost and expense,
return the portion of the Demised Premises to which the Second Supplemental
Tenant Renovations relate to its original, structurally sound condition that
existed prior to Tenant's performance of any Second Supplemental Tenant
Renovations as same are set forth on Exhibit "A", at such time, if at all, as
Tenant should vacate the Building pursuant to the terms of the Lease or
otherwise, reasonable wear and tear excepted. At Landlord's option, Tenant shall
pay to Landlord the cost of such restoration and Landlord will be responsible to
perform the necessary work. In this event, Landlord will provide Tenant with two
proposals comparable in scope of work for the cost of such restoration and
Tenant will obtain one comparable bid proposal. The amount of the payment by
Tenant to Landlord shall be the lowest of the three bids, provided same is
comparable in scope of work. The parties specifically agree that there is no
maximum amount for such restoration and that this restoration is in addition to
other existing restoration requirements of Tenant.

         4. Term. Paragraphs (15) and (16) of the Preamble to the Lease and
Paragraph 5 of the Second Lease Amendment are hereby modified to provide that
the Term shall be extended for an additional term commencing January 1, 2015 and
ending December 31, 2019 so that the Termination Date shall be December 31,
2019.

         5. Fixed Basic Rent. The Lease shall and is hereby modified so that
Fixed Basic Rent for the Period of January 1, 2015 through December 31, 2019
shall mean SIX MILLION TWO HUNDRED FIFTY-ONE THOUSAND SEVEN HUNDRED FIFTY AND
00/100 ($6,251,750.00) DOLLARS.

                           (A) Yearly Rate: ONE MILLION TWO HUNDRED FIFTY
THOUSAND THREE HUNDRED FIFTY AND 00/100
($1,250,350.00) DOLLARS.

ONE HUNDRED NINETY-FIVE AND 83/100
($104,195.83) DOLLARS.

         6. Landlord's Work Allowance. As an inducement to Tenant for entering
into this Fourth Lease Amendment, Landlord shall reimburse Tenant for Second
Supplemental Tenant Renovations in the amount of $200,000. Landlord will
reimburse Tenant in the amount of $50,000.00 per month for four (4) months
commencing at the earlier of the first full month after Tenant commences the
Second Supplemental Tenant Renovations or July 1, 2004.






         7. Successor-in-Interest. This Fourth Amendment of Lease shall inure to
the benefit of and be binding upon the parties hereto and their respective legal
representatives, successors and permitted assigns.

         8. Definitions, Inconsistencies. In the event of any inconsistencies
between this Fourth Amendment of Lease and the Lease, the Fourth Amendment of
Lease shall govern and be binding. All words and terms used in this Fourth
Amendment of Lease and not otherwise defined herein shall have the respective
meanings ascribed to them under the Lease or unless the context clearly requires
otherwise. This Fourth Amendment of Lease was drafted by Landlord as a matter of
convenience and it shall not be construed for or against either party on that
account since Tenant had the opportunity to review same and make changes
thereto.

         9. Ratification of Lease. Except as expressly modified and amended by
this Fourth Amendment of Lease, all of the terms, provisions and conditions of
the Lease are hereby ratified and confirmed by Landlord and Tenant. Tenant
hereby releases and discharges Landlord from any and all claims or liability now
arising out of the Lease prior to the date hereof, including, but in no way
limited to, any and all charges as billed by Landlord to Tenant pursuant to the
terms of the Lease. This does not apply to any estimated billings charged to the
Tenant. In the event of a conflict between the terms of the Lease and the terms
of the Fourth Amendment, the terms of the Fourth Amendment shall control.

         IN WITNESS WHEREOF, the parties have set their hands and seals the date
above first written.
