amended to extend the Initial Term of the Lease for an additional sixty (60) months from the Effective Date.

Section 1.02Renewal.    Section 4 is hereby
deleted and replaced in its entirety as follows:

Section 1.04Lessor's Responsibility to Maintain the Leased
Premises.    Section 12 is hereby amended with the following addition: "Lessor warrants and represents that the hot water, heating and air
conditioning systems and equipment within the Leased Premises are in good working order as of the Effective Date, normal wear and tear and negligence of the Lessee and a Lessee Representative
excepted. The term "Lessee Representative" shall mean any officer, director, member, partner, employee, agent, licensee, assignee, sublessee or invitee of Lessee. Lessee shall within a reasonable
amount of time give Lessor written notice of a defect or need for repairs, after which Lessor shall have reasonable opportunity to repair same or cure such defect. Lessor's failure to repair or cure
such defect after a reasonable notice and right-to-cure period (but in no event less than thirty (30) days) shall be a default hereunder by Lessor. Lessor's liability
with respect to any defects, repairs or maintenance for which Lessor is responsible under any of the provisions of this Lease shall be limited to the cost of such repairs or maintenance or the curing
of such defect."

Section 1.05Notices.    Section 19 is hereby
amended to update the notice address of Lessor:



Article II.BROKER FEES

Section 2.01Broker Fees for Amended Term.    Lessor shall pay CB Richard Ellis
("CBRE"), as Tenant's sole and exclusive representative, a commission the equivalent of four percent (4%) of a $2.75 per rentable square foot NNN rental rate for the Initial Term as outlined in
Section 1.01 of this Amendment (the "Initial Term Commission"). The Initial Term Commission which equals $18,150, is payable immediately upon receipt by Lessor of the first payment of the
extended Initial Term due in July 2005. In the event that Lessor sells the Leased Premises prior to July 1, 2005, then the Initial Term Commission due to CBRE is due upon closing of the
sale of the Leased Premises. Further, in the event that Lessor fails to pay the commission referred to herein within 15 days after it is due, then Lessee may pay such commission to CBRE and
offset rent due to Lessor in the amount of the commission paid to CBRE. In the event that Lessee exercises its option per Section 1.02 of this Amendment for the Renewal Term according to the
exact terms of this Amendment then Lessor shall pay CBRE as Tenant's sole and exclusive representative, a commission the equivalent of a four percent (4%) of a $3.25 per rentable square foot NNN
rental rate (the "Renewal Term Commission"). The Renewal Term Commission is payable immediately upon receipt by Lessor of the first payment of the Renewal Term. In the event that Lessee modifies any
term or condition of this Amendment at the conclusion of the Initial Term but otherwise leases the Leased Premises under new terms and conditions then no Renewal Term Commission will be paid to CBRE
by Lessor.

Article III.OTHER PROVISIONS UNCHANGED

Section 3.01Other Provisions Unchanged.    Except as expressly modified
hereby, the Original Lease amended pursuant to this Amendment shall remain unchanged and in full force and effect.

Article IV.MISCELLANEOUS PROVISIONS

Section 4.01Severability.    If any term or provision of this Amendment or the
application thereof to any person or circumstance shall, to any extent, be invalid or unenforceable, the remainder of this Amendment, or the application of that term or provision to persons or
circumstances other than those as to which it is held invalid or unenforceable, shall not be affected thereby, and each term and provision of this Amendment shall be valid and enforceable to the
fullest extent permitted by law.
