Agreement dated November 28, 2001 by and between NORTHPARK INDUSTRIAL, as Lessor
and IRIS  INTERNATIONAL,  INC.,  formerly known as INTERNATIONAL  REMOTE IMAGING
SYSTEMS,  INC.,  as  Lessee,  for the  premises  located  at 9172  Eton  Avenue,
Chatsworth, CA.

Upon full execution of this Amendment #1, the above  referenced  Lease Agreement
shall be amended as follows:

1.       PARAGRAPH  63 of the  above  referenced  Lease is  hereby  deleted  and
replaced with the following revised Paragraph 63:

         63)      OPTION TO EXTEND (REVISED) - FIRST OF TWO

                  A.       Lessor  hereby  grants to Lessee the option to extend
the term of this Lease for a THREE (3) YEAR AND TEN (10) MONTH period commencing
when the  prior  term  expires  upon  each and all of the  following  terms  and
conditions:

                           (i)      Lessee  gives to Lessor and Lessor  receives
written  notice of the  exercise  of the  option to extend  this  Lease for said
additional  term no earlier  than nine months and no later than six months prior
to the time that the option period would commence if the option were  exercised,
time being of the essence.  If said  notification of the exercise of said option
is not so given and received, this option shall automatically expire;

                           (ii)     The  provisions of paragraph  39,  including
the provision  relating to default of Lessee set forth in paragraph 39.4 of this
Lease are conditions of this Option;

                           (iii)    All of the  terms  and  conditions  of  this
Lease except where specifically modified by this option shall apply;

                           (iv)     On  JANUARY  1,  2007  ,  the  monthly  rent
payable under paragraph 1.5 and 4 of the attached Lease shall be adjusted by the
increase,  if any,  from the date this Lease  commenced  in the  C.P.I.  As used
herein,  the term "C.P.I."  shall mean the Consumer Price Index of the Bureau of
Labor Statistics of the U.S.  Department of Labor for All Urban  Consumers,  Los
Angeles-Anaheim-Riverside,   California   (1982/84=100),   "All  Items",  herein
referred to as "C.P.I."

                                    a.       The   monthly   rent   payable   in
accordance with paragraph A(iv) of this Addendum shall be calculated as follows:
the rent payable for the first month of the term of this Lease,  as set forth in
paragraph  4 of the  attached  Lease,  shall be  multiplied  by a  fraction  the
numerator  of which  shall  be the  C.P.I.  of the  calendar  month  immediately
preceding the effective date of the subject rent escalation, and the denominator
of which shall be the C.P.I.  for the calendar month in which the original Lease
term  commenced.  The sum so calculated  shall  constitute  the new monthly rent
hereunder,  but, in no event,  shall such new monthly  rent be less than 103% of
the  rent  payable  for the  month  immediately  preceding  the  date  for  rent
adjustment.

                                    b.       In the event the compilation and/or
publication of the C.P.I. shall be discontinued,  then the index most nearly the
same as the  C.P.I.  shall be used to make such  calculation.  In the event that
Lessor and Lessee cannot agree on such alternative  index, then the matter shall
be submitted for decision to the American Arbitration  Association in accordance
with the rules of said association and the decision of the arbitrators  shall be
binding upon the parties.  The cost of said Arbitrators shall be paid equally be
Lessor and Lessee.

                                    c.       Lessor shall  notify  Lessee of any
rental  increases  pursuant to this paragraph as soon as  practicable  after the
relevant  C.P.I.  figures have been released.  Until such  notification,  Lessee
shall continue to pay the rent in effect during the prior rental  period.  After
notification of a rental increase,  Lessee shall commence making rental payments
in the increased amount and shall, within ten (10) days after such notification,
pay to Lessor the amount of any rental increases due for previous months.

                  B.       If this  option to extend is  exercised,  the  option
term shall commence on JANUARY 1, 2007 and shall end on OCTOBER 31, 2010 .

                  C.       ON  JANUARY  1,  2008,  JANUARY  1, 2009 AND AGAIN ON
JANUARY 1, 2010 , the monthly rent payable  shall be adjusted  upward by 3% over
the rent payable for the month immediately preceding each rental adjustment.

         OPTION TO EXTEND - SECOND OF TWO

         A.       Lessor  hereby  grants to Lessee the option to extend the term
of this Lease for a FIVE (5) year period  commencing when the prior term expires
upon each and all of the following terms and conditions:

                  (i)      Lessee  gives to Lessor and Lessor  receives  written
notice of the  exercise of the option to extend  this Lease for said  additional
term no earlier  than nine months and no later than six months prior to the time
that the option period would commence if the option were  exercised,  time being
of the essence.  If said  notification  of the exercise of said option is not so
given and received, this option shall automatically expire;

                  (ii)     The   provisions  of  paragraph  39,   including  the
provision  relating  to default of Lessee  set forth in  paragraph  39.4 of this
Lease are conditions of this Option;

                  (iii)    All of the terms and  conditions of this Lease except
where specifically modified by this option shall apply;

                  The rent payable  during this option term shall be  determined
by  multiplying  the square  footage of the premises  times the rate that Lessee
will pay for the  premises  located at  9158-9162  Eton Avenue  pursuant to that
certain Standard Industrial Commercial Single-Tenant Lease - Net (the "9158-9162
Eton Lease") dated as of October 17, 2005 between Lessor, as lessor, and Lessee,
as lessee.  The rent shall be adjusted  every November 1st  accordingly.  In the
event that  Option to Extend set forth in  Paragraph  64 of the  9158-9162  Eton
Lease is not exercised for any reason, the rent payable during this option shall
be determined by  multiplying  the square footage of the premises times the rate
that  would  have been  payable by the  Lessee  under the  9158-9162  Eton Lease
pursuant to Paragraph 64 thereof if such Option to Extend had been exercised and
the  provisions  of said  Paragraph  64 of the  9158-9162  Eton Lease are hereby
incorporated herein by this reference for the purposes of such calculation;  and
the monthly rent shall be adjusted  every  November 1 thereafter  in  accordance
with subparagraph A(v) of said Paragraph 64.

         B.       If this option to extend is  exercised,  the option term shall
commence on NOVEMBER 1, 2010 and shall end on OCTOBER 31, 2015.

         2.       PARKING AGREEMENT: The twenty-one (21) parking spaces referred
to in Paragraph 1 of the Parking  Agreement  attached to the Lease Agreement are
included in the twenty-one (21) parking spaces referred to in Paragraph 1 of the
Parking Agreement attached to the 9158-9162 Eton Lease. In the event that at any
time the Lessee shall not be the lessee under both leases,  the twenty-one  (21)
parking spaces shall be allocated prorata between the two leases on a per square
foot basis.





All other terms and conditions of the above  referenced  Lease  Agreement  shall
remain unchanged and in full force and effect.

Time is of the  essence and this  Amendment  #1 shall be null and void and of no
further  force or effect  unless  signed and returned to us  unchanged  prior to
November 4, 2005.
