                    b)
The “Operating Costs Base Year” as set forth in Section 9.2 of the Lease shall mean
the 2009 calendar year.


                    c)
The “Real Estate Tax Base Year” as set forth in Section 10.2 of the Lease shall
mean the 2009 fiscal year
(i.e. July 1, 2008 through June 30, 2009).


          5. Security
Deposit. Landlord currently holds a Ninety Thousand and 00/100 Dollars ($90,000) letter of credit as the Security
Deposit under the Lease (the “Existing Letter of Credit”) and Tenant shall be required to provide such Security Deposit
to Landlord for the duration of the
Term of the Lease, as extended by this Amendment pursuant to the terms of the Lease.


In addition the following provision is hereby added to the Lease with
respect to the Security Deposit:


“If at any time during the Term of this Lease (as the same may be
extended) Landlord determines
that the financial condition of the issuer of the then current letter of credit
deposited by Tenant with Landlord as
the Security Deposit (the “Letter of Credit”), is such that Landlord’s ability to draw upon the Letter of Credit is, or
in the future may be, impaired, restricted, refused or otherwise adversely affected, then Tenant
shall, within thirty (30) days of Landlord’s written request to Tenant, obtain a replacement Letter of
Credit in substitution for the then current Letter of Credit in the form and amount required herein
from an issuer chosen by Tenant, but reasonably
acceptable to Landlord. Upon Tenant’s delivery of the replacement letter of
credit to Landlord, Landlord shall then simultaneously release the prior
letter of credit being held by Landlord to
Tenant.”


Also, any option in the Lease for Tenant to choose to provide the
Security Deposit in the form of cash versus a letter of credit are hereby
deleted, with the Tenant agreeing that that the Security Deposit shall be required to be in the form of a
letter of credit.


          6. Improvements to Premises. Tenant may improve
the Premises, and shall be entitled to the
allowance for improvements, pursuant to the terms and conditions set forth in
the work letter attached hereto as Exhibit C.


          7. Roof Access for Wi-Fi Antenna. Tenant shall have the right to access and use of
the roof of the Building for a single antenna in accordance with the
terms and provisions of Exhibit D attached
hereto.


          8. No Further Extension, Expansion Rights or Rights
of First Refusal. Following
execution of this Amendment, Tenant shall have no further expansion rights,
rights of first offer, rights of
first refusal or other similar rights under the Lease to lease additional space
in the Building, or any further
extension rights except as expressly provided for in this Amendment and any
other such rights are hereby deleted from the Lease.


          9. Brokers. With respect to this Amendment, each of Landlord and Tenant warrants that it has dealt with no other brokers in
connection with the negotiation and execution of this Amendment, other than CB Richard Ellis NE (the
“Broker”). Tenant and Landlord shall each


-3-





indemnify the other against all costs, expenses, attorneys’ fees and
other liability for commissions
and other compensation claimed in connection with this Amendment by any other broker or agent, other than the Broker, claiming
the same by, through or under the indemnifying party. Landlord shall be solely responsible for payment of any fees or
commissions due to Broker, pursuant
to the terms of a separate agreement.


          10. Miscellaneous.
Except as herein modified or amended, the provisions, conditions and terms of the Lease shall remain unchanged and
in full force and effect. Tenant represents and warrants to Landlord that as of the date hereof, (a) the Lease is
and remains in good standing and in
full force and effect, and (b) to the best of Tenant’s knowledge after
reasonable inquiry, Tenant has no
claims, counterclaims, set-offs or defenses against Landlord arising out of the
Lease or in any way relating thereto
or arising out of any other transaction between Landlord and Tenant, and Landlord is not in default of any of
its obligations under the Lease. In addition, the Tenant represents and warrants to the Landlord
that, all tenant finish-work allowances or other payments to be provided to Tenant under the Lease or otherwise, and all
improvements to be performed by
Landlord, if any, have been paid in full and completed, respectively, by
Landlord, and Landlord has no further
obligations with respect thereto. Tenant’s covenants to pay Base Rent and Additional Rent under the Lease are
independent of every other covenant in this Lease.


          11. Execution.
This Amendment may be executed in two (2) or more counterparts, each of which shall be an original but such
counterparts together shall constitute one and the same instrument notwithstanding that both Landlord
and Tenant are not signatories to the same counterpart. Delivery of an executed counterpart of this Amendment by
facsimile shall be equally as
effective as delivery of any original executed counterpart. Any party
delivering an executed counterpart of this Amendment by facsimile also shall
deliver an original executed counterpart of this Amendment, but the
failure to deliver an original executed counterpart shall not affect the
validity, enforceability and binding effect of this Amendment. Signature and acknowledgement pages may be detached from the
counterparts and attached to a single copy of this Amendment to physically form
one (1) document.
