      A.    By Lease and Addendum to Lease by and between Glenborough

conditions set forth below.
            NOW, THEREFORE, Landlord and Tenant hereby agree as follows:

                                 A G R E E M E N T

      1.    Effective immediately, Section 2.5. of the Lease is modified and

  January 1, 2008,      through      December 31, 2008,      $10,550.65 / month

      3.    Tenant desires to construct a "clean room" in its Premises and to
perform certain other work to be determined later, and Landlord has consented,
on and subject to the following provisions:
            Landlord shall provide an allowance (the "Allowance") in an amount
not to exceed the lesser of $50,000.00, or Tenant's actual construction costs,
for construction of its clean room and other improvements in its Premises (such
work, hereafter, the "Leasehold Improvements"), as incurred prior to December
31, 2004. Landlord shall disburse the Allowance to Tenant, prior to completion
of such work, in the form of four (4) quarterly payments of $12,500.00 each
commencing March 31, 2004. Within not more than sixty (60) days after December
31, 2004, Tenant shall provide third-party invoices for all portions Leasehold
Improvements work performed prior to December 31, 2004, detailing the dates on
which such work was performed. Tenant understands and agrees that the Allowance
shall only be available for those portions of the Leasehold Improvements
performed prior to December 31, 2004, and Tenant shall return any portion of
the Allowance not applicable to Leasehold Improvements performed prior to such
date. Reimbursable categories of expense shall include design work; permitting
costs; plan check fees, engineering costs; generic HVAC upgrades, if required;

                                        1

clean-room specific HVAC upgrades as required; clean-room specific door,
window, ceiling, and floor modifications; cabling costs; and actual
construction costs. Non-reimbursable categories of expenses shall include
furniture, equipment, and other personal property costs.
            Tenant may commence construction of the Leasehold Improvements at
any time after the date of this Agreement or execution by Landlord, whichever
is later.
            Once commenced, Tenant shall diligently complete the Leasehold
Improvements, to minimize disruption in the Building, and shall secure a
guarantee of the Leasehold Improvements of not less than one (1) year. Landlord
shall reimburse Tenant for allowable costs of the Leasehold Improvements out of
the Allowance once construction is completed, as detailed above.
            Construction of the Leasehold Improvement shall also be subject to
the following general conditions:
(a) The Leasehold Improvements shall be installed and/or constructed by or
    under the direction of Tenant but be subject to Landlord's ongoing review
    and approval. Tenant shall promptly and diligently install and/or construct
    the Leasehold Improvements and the specifications for the Leasehold
    Improvements shall be at least Building Standard, or the quality of the
    pre-existing improvements in the Premises, except where waived in writing
    by Landlord.

(b) If Tenant elects to perform work that requires any building permit or
    involves relocating walls or doors, then Tenant shall provide Landlord with
    copies of a preliminary space plan and specifications (collectively, the
    "Space Plan") and, after Landlord has approved or made changes to the Space
    Plan, with final construction drawings and specifications (collectively,
    the "Construction Drawings") detailing such work for Landlord's review and
    approval. No Space Plan or Construction Drawings shall be required for
    carpet, paint, and updating lighting and other fixtures. Tenant shall
    obtain all required building permits at its own cost (but subject to
    subsequent reimbursement out of the Allowance) and shall provide Landlord
    with copies. Landlord shall reasonably and promptly sign any building
    permit applications where the owner's signature is required, provided that
    Tenant hereby agrees to protect, defend, and indemnify Landlord from any
    liabilities arising there from.

(c) Tenant's general contractor ("General Contractor") and all subcontractors
    shall be subject to the reasonable approval of Landlord and, at request of
    Landlord if generally required for work in the Building, shall employ only
    union workers. General Contractor and all subcontractors shall be licensed
    and qualified to do business in the State of Minnesota.

(d) Tenant's General Contractor shall provide Landlord with Certificates of
    Insurance:  (i) naming Landlord, its property manager, and any other
    parties designated by Landlord, as additional insureds, as their respective
    interests may appear; (ii) evidencing general liability, owner's and
    contractor's protective ("OCP") liability, and property damage insurance
    with respect to the work of Leasehold Improvements of at least One Million
    Dollars ($1,000,000.00) combined single limit for bodily injury, death and
    property damage liability or such other limits that seem appropriate to the
    scope of the work and financial capacity of the contractor; and (iii)
    evidencing Workers' Compensation insurance in compliance with State law.
    The preceding insurance is in addition to Tenant's insurance obligations
    under the Lease.

(e) Landlord reserves the right to enter the Premises (i) to post such notices,
    including, without limitation, notices of non-responsibility for mechanics'
    liens, as Landlord deems necessary, and (ii) to inspect the progress and
    quality of the Leasehold Improvements.

(f) Tenant shall take all reasonable steps necessary to ensure that the
    Leasehold Improvements shall be installed and/or constructed in a manner
    that will not interfere with the quiet enjoyment of other tenants and of
    guests entering the lobby including, without limitation, complying with
    Landlord's existing rules and regulations, if any, for contractors and/or
    for construction work in the Building and with any separate or additional
    reasonable directives of Landlord. Tenant shall ensure that the work area
    is kept clean and that construction material does not block any corridor,
    hallway, walkway, driveway, or other passageway commonly used by other
    tenants or by maintenance personnel. Tenant shall bring construction
    materials to the Premises in the manner, and during time periods, specified
    by Landlord to minimize impact on other tenants, on Building guests, and on
    the Building. Tenant shall be responsible for all clean-up and disposal of
    waste, which shall not be disposed of, other than in minor quantities

                                        2

    consistent with normal Premises usage, in Building trash containers.

(g) Tenant shall diligently commence and pursue the Leasehold Improvements to
    completion in accordance with the requirements of this Section and shall be
    solely responsible for any delays in completion. Upon substantial
    completion of the Leasehold Improvements, Landlord, Tenant, any space
    planner or architect, and General Contractor shall walk the Premises
    together and either agree the Leasehold Improvements are complete or agree
    upon a list of minor corrective and finish items ("punch list" items)
    remaining to be done. In addition, not later than ninety (90) days after
    substantial completion, Tenant shall obtain, and provide Landlord with, any
    applicable certificate of occupancy or other evidence of final approvals
    from appropriate municipal authorities, if available, with copies of
    invoices for the Leasehold Improvements indicating payment in full, and
    with final, unconditional mechanics' lien releases. Tenant shall diligently
    pursue correction and/or completion of any outstanding punch list items
    and, at the request of Landlord, shall certify upon their completion that
    the Leasehold Improvements have been completed according to "as-built"
    plans and specifications, providing Landlord with one complete set of such
    "as-built" plans and specifications for any Leasehold Improvements
    requiring a building permit, in CD-ROM format if requested by Landlord.

(h) Landlord understands and agrees that the Leasehold Improvements may not be
    completed prior to December 31, 2004. Tenant understands and agrees that
    the Allowance is only applicable to work prior to such date.

(i) Landlord shall not be liable to Tenant for any noncompliance of the
    Leasehold Improvements with building codes or other laws or regulations
    notwithstanding Landlord's review and approval of the Space Plan and
    Construction Drawings and any inspection and approval of the Leasehold
    Improvements. Tenant shall be solely responsible for complying with all
    laws and regulations including, without limitation, the American's with
    Disabilities Act and with any energy conserving laws or requirements; but
    Landlord shall be responsible for path of travel to the Premises, unless
    Tenant has relocated entry doors.

      4.    All other terms, covenants, and conditions of the Lease, shall
remain in full force and effect.

            This Agreement modifies and amends the Lease. To the extent there
are any inconsistencies between this Agreement and the Lease, the terms,
covenants, and conditions of this Agreement shall govern. Capitalized terms not
defined herein are defined in the Lease.

            IN WITNESS WHEREOF, Landlord and Tenant have executed this
Agreement as of the date first above written.
