Dear Mr. Wall:

        Pursuant to Section 27K of the Leases (referencing amending each Lease),
this letter, when signed by an authorized representative of each Tenant, shall
serve as an amendment (the "Second Extension Amendment") to each of the Leases
referenced above (as amended by Extension Amendment dated January 10, 2008).

        The Initial Term (as that term is defined in each such Lease) is hereby
extended to and will expire on March 31, 2009.

        For clarification and avoidance of doubt, Section 2 of each Lease (with
respect to extending the terms of each Lease) provides in part that the Tenant
may extend its option to renew by notice in writing to the Landlord served at
least six (6) months and not more than twelve (12) months prior to the end of
the Initial Term or the then-current Option Period, as the case may be.
Therefore, in order for the Tenant to exercise its option to extend the Initial
Term of each Lease (should the Tenant so desire to exercise such right(s)) due
to expire on March 31, 2009, as provided for in this Second

--------------------------------------------------------------------------------

Extension Amendment, the Tenant must serve a notice in writing upon the Landlord
no later than September 30, 2008.

        If this Second Extension Amendment or the signature page, as executed,
is transmitted by one party to the other by facsimile transmission or electronic
"pdf" transmission, such transmission shall be deemed an executed original of
this Second Extension Amendment and of such signature.

        Except as modified by this Second Extension Amendment, the Leases remain
unchanged.

        If the Tenants agree to the terms and provisions of this Second
Extension Amendment, please have an authorized representative of each Tenant
sign below and thereafter either fax or pdf to me the original hereof.
