                                   WITNESSETH:

        WHEREAS, by lease dated March 25, 2002, as amended by First Amendment to
Lease dated February 18, 2003 (the "First Amendment") (the lease and the First

        WHEREAS, Lessor and Lessee desire to extend the term of the Lease on the

        NOW, THEREFORE, in consideration of the mutual covenants and agreements
herein set forth, Lessor and Lessee hereby agree as follows:

        l. EXTENDED TERM. The term of the Lease is hereby extended to April 30,

        2. REAL ESTATE BROKERS. Lessee represents that it has dealt with, and
only with Van Vlissingen and Co., as broker in connection with this Amendment
and that, insofar as Lessee knows, no other broker negotiated this Amendment or
is entitled to any commission in connection therewith. Lessee agrees to
indemnify and hold Lessor harmless from all damages, liability and expense
(including reasonable attorneys' fees) arising from any claims or demands of any
other broker or brokers or finders in connection with its participating with
Lessee in the negotiating of this Amendment.

        3. LEASE IN FULL FORCE AND EFFECT. Except for the provisions of this

rights and obligations of Lessor and Lessee thereunder, shall remain in full
force and effect, and are not otherwise altered, amended, revised or changed.

        4. ESTOPPEL. Lessee hereby acknowledges that as of the date hereof,
Lessee has no knowledge of any claims arising under the Lease against Lessor or
its agents, or any one or more of the foregoing, and that Lessee knows of no
default or failure on the part of Lessor to keep or perform any covenant,
condition or undertaking to be kept or performed by Lessor under the Lease.
Lessee hereby releases Lessor from any known liability arising under the Lease
prior to the date hereof.
