EXHIBIT 10.2 AMENDMENT #1 dated October 17, 2005, for reference purposes only, to Lease 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.
