                           FIRST AMENDMENT TO LEASE

    THIS FIRST AMENDMENT TO LEASE (the "First Amendment") is entered into 
effective as of April 1, 1998 by and between KILROY REALTY, L.P, a Delaware 
limited partnership ("Landlord") and PRINTRAK INTERNATIONAL INCORPORATED, a 
California corporation ("Tenant") with respect to the following facts:

                                    REALTY

    A.  Landlord is under contract to purchase certain real property commonly 
known as 1250 North Tustin Avenue, Anaheim, California (the "Premises") from 
RICOL, LLC, a California limited liability company ("RICOL"). Tenant is the 
tenant of the Premises pursuant to the certain written Commercial Lease, 
dated May 12, 1995, by and between RICOL and Tenant (the "Lease").

    B.  Subject to Landlord's acquisition of title to the Premises, Landlord 
and Tenant desire to amend the Lease upon the terms and conditions set forth 
herein.

                                   AGREEMENT

    NOW, THEREFORE, IN CONSIDERATION OF the foregoing Recitals and for other 
good and valuable consideration, the receipt and sufficiency of which are 
hereby acknowledged, Landlord and Tenant hereby agree as follows:

    1.  CAPITALIZED TERMS.  The defined terms used in this First Amendment, 
as indicated by the first letter of a word being capitalized, shall have the 
same meaning in this First Amendment as such terms and provisions have in the 
Lease.

    2.  CONDITION TO FIRST AMENDMENT.  The effectiveness of this First 
Amendment shall be conditioned solely upon the close of escrow and Landlord's 
acquisition of legal title to the Premises.

    3.  COMMENCEMENT DATE AND TERM.  Section 2.1 of the Lease is hereby 
amended to extend the Term of the Lease such that the Term shall be for a 
period of six (6) years commencing May 1, 1998, and ending April 30, 2004, 
unless sooner terminated in accordance with the provisions of the Lease. In 
the event that Landlord obtains title to the Premises prior to May 1, 1998, 
rent shall be prorated on a daily basis and payable by Tenant to Landlord 
with the first installment of rent due under the Lease, unless April rent is 
prorated through escrow in connection with Landlord's acquisition of the 
Premises.

                                       1

    4.  MONTHLY RENTAL.  Section 4.1 of the Lease is hereby amended to 
provide that Monthly Rental shall be Fifty-Eight Thousand Eighty-Seven 
Dollars and Sixty-Five Cents ($58,087.65) per month, commencing May 1, 1998, 
subject to adjustment as set forth in the Lease.

    5.  ADJUSTMENT TO RENTAL.  Section 4.2 of the Lease is hereby amended to 
provide that the annual increases in Monthly Rental pursuant to Section 4.2 
shall not be greater than six percent (6%), nor less than three percent (3%), 
for any single year during the Term.

    6.  OPTION TO RENEW:  Tenant shall have the option to extend the Term of 
the Lease for one (1) additional five (5) year period (the "Additional 
Term"). Such option shall be exercised, if at all, by written notice of 
Tenant's election to exercise the option delivered to Landlord no earlier 
than two hundred seventy (270) days, nor later than one hundred eighty (180) 
days, prior to the expiration of the Term of the Lease. If Tenant fails 
timely to exercise or is not entitled to exercise this option to renew, then 
Tenant's option to renew shall automatically lapse and thereafter not be 
exercisable by Tenant. If Tenant is entitled to and does give notice in the 
manner and within the time frame set forth in this paragraph, then the Term 
shall be extended by the Additional Term, on all of the conditions set forth 
in the original Lease; provided, however, that:

        (1)  Monthly Rental for the Additional Term shall be equal to the 
then "Fair Market Rental Rate" (as defined below) of the Premises. Landlord 
shall, in response to and within thirty (30) days after receipt of Tenant's 
notice of exercise of the option to renew, give Tenant written notice of the 
then applicable "Fair Market Rental Rate" as determined in good faith by 
Landlord. "Fair Market Rental Rate" means the then prevailing annual rental 
rate per square foot of rentable area in comparable buildings in the Anaheim, 
CA, industrial area, comparable in area and location to a Premises. Not later 
than thirty (30) days after Landlord's notice to Tenant of the applicable 
"Fair Market Rental Rate", Tenant shall timely notify Landlord of Tenant's 
election to (i) have the "Fair Market Rental Rate" determined by the 
"appraisal" procedure described below, or (ii) accept Landlord's 
determination of the "Fair Market Rental Rate", or (iii) elect not to 
exercise Tenant's option to extend. If Tenant fails to notify Landlord within 
such thirty (30) day period of Tenant's election, then Tenant shall be deemed 
to have accepted Landlord's determination of "Fair Market Rental Rate" and to 
have waived its right to an appraisal. Tenant's notice under subparagraphs 
(i) or (ii) shall be deemed Tenant's exercise of the option to extend the 
Term.

    If Tenant exercises its option to renew and timely elects to have the 
"Fair Market Rental Rate" determined by appraisal, then each party shall 
appoint an appraiser within forty (40) days after such exercise date. The two 
appraisers shall within a period of five additional days, agree upon and 
appoint an additional appraiser. The three appraisers shall, within thirty 
(30) days after the appointment of the third appraiser, determine the Fair 
Market Rental Value of the Premises in writing and submit their report to all 
of the parties. The Fair Market Rental Value shall be determined by 
disregarding the appraiser's valuation that diverges the greatest from each 
of the other two appraisers' valuations, and the arithmetic mean of the 
remaining two appraisers' valuations shall be the Fair Market Rental Value. 
Each party shall pay for the services of the appraiser selected by it, plus 
one half of the fee charged by the third appraiser, and one half of all other 
costs relating to the determination of Fair Market Rental Value;

        (2)  There shall be no commissions payable in connection with the 
exercise of the option to renew; and

        (3)  This option is personal to Tenant and there shall be no further 
options to extend the Term.

     7.  PERMITTED USE.  Notwithstanding anything set forth in Section 7.1 of 
the Lease to the contrary, Landlord's written consent to Tenant's request to 
change the permitted use of the Premises shall not be unreasonably withheld.

     8.  POLICY FORM--DEDUCTIBLE.  Notwithstanding the last sentence of 
Section 11.2, the policies maintained by Tenant pursuant to Section 11.1(a) 
(comprehensive or commercial general liability), Section 11.1(e) (leasehold 
improvements) and Section 11.1(g) (all-risk, direct physical loss or damage) 
may be subject to a deductible of not more than Twenty Five Thousand Dollars 
($25,000).

     9.  ESTOPPEL CERTIFICATE AND NON-DISTURBANCE AGREEMENT.  The Estoppel 
Certificate referred to in Section 15.3, and the non-disturbance agreement 
referred to in Section 15.4 of the Lease shall, at the option of Landlord or 
Landlord's lender, each be in the customary, commercially reasonable, form of 
the requesting lender or of the purchaser of all or a portion of the Premises.

    10.  MEMORANDUM OF LEASE.  Section 19.14 is hereby deleted in its 
entirety, and, at Tenant's option, Landlord and Tenant shall execute and 
record a short form memorandum of lease in form and substance reasonably 
acceptable to Landlord.

    11.  SERVICE CHARGE.  Section 19.24 is hereby deleted in its entirety.

    12.  ENVIRONMENTAL MATTERS--TENANT'S OBLIGATIONS.  Section 19.25(b)(1)(i) 
is hereby amended by the addition of the following language: "provided, 
however, that the foregoing covenant shall not extend to materials typically 
found or used in computer software and hardware research and development 
applications so long as (a) such materials and any equipment which generates 
such materials are maintained only in such quantities as are reasonably 
necessary for Tenant's operations in the Premises, (b) such materials are 
used strictly in accordance with all Environmental Laws and the 
manufacturers' instructions therefor, (c) such materials are not disposed of 
in or about the Premises in a manner which would constitute a release or 
discharge thereof, and (d) all such materials and any equipment which 
generates such materials are removed from the Premises by Tenant upon the 
expiration or earlier termination of this Lease."

    In addition, Section 11.5 of the Lease is hereby amended by adding the 
following to the end of both clauses (iv) and (v): "...as a result of the 
negligence or willful misconduct of Tenant, its agents, employees, invitees 
or contractors; provided, that Tenant acknowledges its duty to supervise and 
control access to the Premises in a commercially reasonable and prudent 
manner."

    13.  BROKERS.  Tenant warrants and represents that it has not dealt with 
any real estate broker or agent in connection with this First Amendment or 
its negotiation. Tenant shall indemnify and hold Landlord harmless from any 
cost, expense or liability (including costs of suit and reasonable attorneys' 
fees) for any compensation, commission or fees claimed by any other real 
estate broker or agent in connection with this First Amendment or its 
negotiation by reason of any act of Tenant.

    14.  NOTICE.  The address of Lessor for purposes of notices is hereby 
amended to provide the following addresses for notice to Landlord:

    15.  IMPROVEMENTS.  Notwithstanding Section 8.3, but subject to 
Landlord's prior written approval of detailed plans and specifications to be 
submitted by Tenant at least thirty (30) days prior to commencement, Tenant 
shall be permitted to construct certain improvements and alterations to the 
Premises consisting of administrative offices in the central area of the 
first floor and the installation of an elevator near the lobby. Tenant shall 
be responsible for all such construction and obtaining all necessary permits 
and approvals therefor, and shall give Landlord at least twenty (20) days 
notice prior to commencement to allow Landlord to record and post notices of 
non-responsibility. Tenant shall maintain the Premises free of mechanic's or 
materialmens' liens and shall indemnify defend and hold Landlord harmless 
from and against any claims, liability or damages, including reasonable 
attorneys' and experts' fees arising out of such construction. All such 
improvements and alterations shall be the property of Landlord and shall 
remain upon and be surrendered with the Premises upon expiration of the Term, 
unless Landlord elects to require their removal. Landlord shall reimburse 
Tenant for the actual costs, in the approximate amount of Two Hundred 
Thousand Dollars ($200,000), incurred by Tenant in constructing the approved 
improvements and alterations; provided, that the amount reimbursed, plus 
interest thereon at the rate of ten percent (10%) per annum, shall be 
amortized over the portion of the Term remaining as of the date of such 
reimbursement payment, and shall be repaid to Landlord thereafter in monthly 
installments which shall be added to and considered a part of the Monthly 
Rental due and payable by Tenant under the Lease.

    16.  LEASE IN EFFECT.  Landlord and Tenant acknowledge and agree that the 
Lease, except as amended by this First Amendment, remains unmodified and in 
full force and effect in accordance with its terms.

    17.  ENTIRE AGREEMENT.  This First Amendment, together with the Lease, 
embodies the entire understanding between Landlord and Tenant with respect to 
the subject matter hereof and can be changed only by an instrument in writing 
executed by both Landlord and Tenant.

First Amendment, the terms and conditions of this First Amendment shall 
control and govern the rights and obligations of the parties.
