EXHIBIT 10.9

                          ADDENDUM TO YORK, U.K. LEASE
                                 (FEBRUARY 2004)

         THIS ADDENDUM TO YORK, U.K. LEASE ("Second Addendum") amends the Lease
between BIO-METRICS PROPERTIES, LTD. ("Landlord") and ACCENT OPTICAL
TECHNOLOGIES (U.K.) LTD. (formerly known as ACCENT SEMICONDUCTOR TECHNOLOGIES
(U.K.) LTD., "Tenant") dated July 28, 2000 ("Original Lease"), which Original
Lease was previously amended by an Addendum to and Extension of Lease dated
January 28, 2003 ("First Addendum") (such Original Lease and First Addendum
being referred to herein collectively as the "Lease"). The Lease as amended by
this Second Addendum shall be referred to as the "Amended Lease."

         The parties hereby agree as follows to amend the Lease to effect the
following:

         1.       Section 1.1.13 (as previously amended by the First Addendum)
shall be amended to read as follows: "The "Term" shall mean the "Initial Term,"
the "Extended Term" and, if any of the Options (as defined in Section 4.7) are
exercised, the "Option Terms" (as defined in the next sentence). The "Initial
Term" shall mean the period from July 28, 2000 to February 28, 2003, the
"Extended Term" shall mean the period from March 1, 2003 to February 28, 2006"
and the "Option Terms" shall mean March 1, 2006 to February 28, 2007 as to the
first Option under Section 4.7 of the Amended Lease and March 1, 2007 to
February 29, 2008 as to the second Option under Section 4.7 of the Amended
Lease. Unless otherwise defined herein, defined terms shall the meaning or
definition used in the Lease.

         2.       Notwithstanding anything contained in the Lease, Tenant shall
be responsible for "Operating Expenses" and "Repairs." For purposes of this
Agreement, "Operating Expenses" shall include all costs and expenses of every
kind and nature incurred with respect to the use, occupancy, maintenance and
operation of the Premises, except Repairs (as defined herein). For purposes of
this Agreement, "Repairs" shall mean (i) the expenses listed in Section 5.2 of
Exhibit 5 to this Second Addendum for the Initial Term through the date of this
Addendum; and (ii) for the period from the date of this Addendum through
termination of the Lease, including the Extended Term, and, if applicable, the
Option Terms, the maintenance and repairs listed in Exhibit 5 for which Tenant
shall be responsible at Tenant's cost; provided, if the cost of such structural
repairs in Section 5.1 exceeds or would exceed $50,000 in any one lease year
(3/1 to 2/28, 2/29 in a leap year; provided, for such purposes the period from
1/28/03 to 2/28/03 shall be included in the period 3/1/03 to 2/29/04), Tenant
may elect to terminate the Lease, rather than make such repair(s). Landlord
agrees that, if the cost of any such repair is covered by Landlord's insurance
policy for the Building, Landlord will make the proceeds available to Tenant to
make any repairs under Section 5.1; provided, Tenant shall pay fifty percent
(50%) of any deductible up to $50,000 per lease year. Notwithstanding anything
contained herein, If Landlord determines that Tenant can not continue to occupy
the Premises without structural repair or other maintenance to the portions of
the Building not comprising the Premises (due to violations of building codes,
condemnation due to the property's condition or similar factors), then Landlord
may elect to terminate the Lease, unless Tenant agrees to make such repairs or
perform such

                                                                          PAGE 1


maintenance within fifteen (15) days of notice of the need for such repairs or
maintenance from Landlord.

         3.       A new Section 4.7 shall be added to the Lease to read as
                  follows:

         "Section 4.7. RENEWAL OPTION. If the lease is not in default when each
         option is exercised or when the renewal term is to commence, Tenant
         shall have the option to renew this lease for two successive terms of
         one year each (the "Options"), as follows:

         (1)      Each of the renewal terms shall commence on the day following
         expiration of the preceding term, the current term being the Extended
         Term, with the first option to cover the period from March 1, 2006 to
         February 28, 2007 and the second option to cover the period from March
         1, 2007 to February 29, 2008.

         (2)      The option may be exercised by written notice to Landlord
         given not less than 60 days before the last day of the expiring term.
         Giving such notice shall be sufficient to make the lease binding for
         the renewal term without further act of the parties.

         (3)      The terms and conditions of the lease for each renewal term
         shall be identical with the original term, except for rent and that
         Tenant will no longer have any option to renew this lease that has been
         exercised. The monthly rent in Section 2 of the Lease shall be
         increased to 12,100 pounds sterling per month for the First Option
         Period (a 10% increase from the Extended Term) and to 13,210 pounds
         sterling for the Second Option Period (a 10% increase). Section 2 of
         the Lease is hereby amended to reflect such rent changes."

         4.       The parties agree that the Lease, as amended herein, shall
         remain in full force and effect through the remainder of the Term,
         subject to earlier cancellation as provided herein. The Lease, as
         amended herein, shall be interpreted to give full force and effect to
         the modifications herein.

         IN WITNESS WHEREOF, the undersigned have executed this Agreement
effective this 9th day of February 2004.
