| | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
| | 1.     The above and
    foregoing premises are incorporated by reference.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
|
| | 2.     The Term of the
    Sublease (as such term set forth in Section 5 of the
    Sublease and is used throughout the Sublease) shall be extended
    for a period of one (1) year from the date that such Term
    would have otherwise expired, so that such Term (as amended
    hereby) shall end on March 14, 2004, unless
    otherwise sooner terminated in accordance with the provisions of
    the Subleases.                                                                                                                                                                           
|
| | 3.     Section 6.1
    of the Sublease shall be revised such that minimum rent (as such
    minimum rent is referenced in the Sublease) shall be an amount
    equal to Three Thousand Dollars ($3,000) per month (the
    Revised Minimum Rent). Such Revised Minimum
    Rent shall be due and payable by Sublessee in advance on the
    first day of each month beginning after the Effective Date of
    this Amendment and extending through the Term (as amended by
    Section 2 of this Amendment), to such address and pursuant
    to such other terms as may be found in the Sublease.
|
| | 4.     Section 6.2
    of the Sublease shall be revised such that Sublessee shall be
    liable for additional rent during each month of the Term
    (beginning on the Effective Date of this Amendment) in the
    amount of twenty percent (20%) of the Operating Costs (as
    such term is defined in Section 6.2 of the Sublease), which
    is estimated to be the sum of Six Hundred Dollars ($600) per
    month.                                                                                                                                                                          
|
| | 5.     The parties
    respective obligations with respect to the Amendment are
    specifically conditioned upon obtaining the written consent from
    Prologis Limited Partnership, lessor of the Premises, below. In
    the event the parties fail to obtain such written consent, this
    Amendment shall be deemed null and void, and of no force and
    effect.

    demised by the foregoing Sublease) except in accordance with the
    terms and conditions of the Prime Lease; and

| | f. | If Landlord terminates the Prime Lease as a
    result of a default by Sublandlord thereunder, the Sublease
    shall automatically terminate concurrently, therewith unless
    Landlord elects in writing to keep the Sublease in full force and
    effect in which case the Sublease shall become and be deemed to
    be a direct indenture of lease between Landlord and Subtenant.
