AGREEMENT

     This Software Developer Services Agreement
(this "Agreement") is entered into as of July 8, 2002 by and between
OSI Systems Pvt. Ltd., a corporation formed and existing under the laws of India
("OSPL"), and Imagis Technologies Inc., a British Columbia, Canada
corporation ("Imagis"), with reference to the following facts:

     A.     OSPL is in the
business of providing software development services to others.

     B.     Imagis is in
the business of developing, marketing and selling biometric systems, including
facial recognition systems, including software.

     C.     Imagis desires
to engage OSPL's software development capacity, and OSPL desires to accept such
engagement.

     Therefore, the parties agree as
follows:

1     OSPL DUTIES. During the Term (as
defined below), OSPL shall have the following duties:

          1.1.  
Personnel.  OSPL shall provide Imagis with the services of its software
engineers, including a project supervisor (collectively, the
"Personnel"), at times and in capacities to be mutually agreed.

          1.2.  
Facilities and Equipment.  OSPL shall provide facilities and equipment
for the Personnel's use, within OSPL's Hyderabad, India facilities.  Such
facilities and equipment shall be equivalent to the facilities and equipment
used by OSPL's other comparable software development personnel, and OSPL shall
maintain such facilities and equipment to such standard.  Facilities shall not
include any dedicated communications lines.

          1.3.  
Advice.  Upon reasonable request by Imagis, OSPL shall advise Imagis with
respect to labor laws and practices applicable to the Personnel.

          1.4.  
No Supervision or Performance Related Duties.  OSPL shall be under no
obligation to supervise the Personnel or otherwise perform any duties in
relation to the Personne's work or the completion of that work.

2     IMAGIS DUTIES.  Imagis shall have the
following duties:

          2.1.  
Project Management.  Imagis shall be responsible for the selection and
oversight of the Personnel's work and the timeliness, quality and completion of
that work.  Imagis shall assign to the Personnel only work that is permissible
under applicable laws and regulations, including laws and regulations pertaining
to intellectual property and applicable labor laws.

          2.2.  
Payments.  OSPL shall bill Imagis for each Personnel on an hourly basis,
at 85% of the fair market value for such Personnel, to be determined.  Line
engineers will be priced at $18 per hour.  Imagis shall also reimburse OSPL for
any out-of-pocket costs arising solely from the performance of its obligations
hereunder.  OSPL shall invoice Imagis monthly for such amounts, and Imagis shall
pay each invoice within 30 days of the date of the invoice.  Regardless of the
number of hours worked by the Personnel, and the fair market value of such
services, Imagis shall pay OSPL a minimum of $250,000 (or its equivalent in
Indian rupees) during the Term.  If, at the expiration or termination of this
Agreement, the total amount Imagis has paid for OSPL services hereunder is less
than $250,000, Imagis shall, within 10 business days after such expiration or
termination, pay OSPL the difference between (i) the amount Imagis has paid
under this Agreement up to the expiration or termination, and (ii) $250,000.

judgment shall include an attorneys' fees clause that shall entitle the judgment
creditor to recover attorneys' fees incurred to enforce a judgment on this
Agreement, which attorneys' fees shall be an element of post-judgment costs; the
parties agree that this attorneys' fee provision shall not merge into any
judgment.

          8.12.  
LIMITATION ON LIABILITY; REMEDIES. NEITHER PARTY SHALL BE LIABLE TO THE

          8.15.  
No Partnership or Joint Venture.  This Agreement does not create a
partnership or joint venture between the parties, and shall not be construed as
doing so.  This Agreement does not create any right by either party to bind the
other party.

Agreement.

but not limited to attorneys' fees, incurred by such holders of the Notes in
collecting any sums due on the Notes or in otherwise enforcing any of their
rights.

     8.6. Remedies Cumulative. No right or remedy conferred upon or reserved to
any holder of Notes under this Agreement is intended to be exclusive of any

notice of the occurrence of a Default or an Event of Default. Such notice shall
specify the nature of such default, the period of existence thereof and what
action the Company has taken or is taking or proposes to take with respect
thereto,

     (b) If the bolder of any Note or of any other evidence of Debt of the
Company or any Subsidiary gives any notice or takes any other action with
respect to a claimed default, the Company will forthwith give written notice
thereof to each holder of the then outstanding Notes, describing the notice or
action and the nature of the claimed default.

ss.9. AMENDMENTS, WAIVERS AND CONSENTS

     9.1. Matters Subject to Modification. Any term, covenant, agreement or
condition of this Agreement may, with the written consent of the Company, be
amended, or compliance therewith may be waived (either generally or in a
particular instance and either retroactively or prospectively), if the Company
shall have obtained the consent in writing of the holder or holders of 51% or
more in aggregate principal amount of outstanding Notes; provided, however,
that, without the written consent of the holder or holders of all of the Notes
then outstanding, no such amendment, waiver, modification or alteration shall be
effective which will (i) change army of the provisions, including definitions,
relating to payment (including any required prepayment or optional prepayment)
of the principal of, Make-Whole Amount or interest on any Note, (ii) change the
amount of any payment or prepayment of principal or Make-Whole Amount, or change
the rate of interest thereon, or (iii) change any of the provisions of Section
8.1, Section 8.2, Section 8.3 or this Section 9.

     For the purpose of determining whether holders of the requisite principal
amount of Notes have made or concurred in any amendment, waiver, consent,
approval, notice or other communication under this Agreement, Notes held in the
name of, or owned beneficially by, the Company, any Subsidiary or any Affiliate
thereof, shall not be deemed outstanding.

     9.2. Solicitation of Holders of Notes. Neither the Company nor any Person
acting on the Company's behalf will solicit, request or negotiate for or with
respect to any proposed waiver or amendment of any of the provisions of this
Agreement or the Notes unless each holder of the Notes (irrespective of the
amount of Notes then owned by it) shall concurrently be informed thereof by the
Company and shall be afforded the opportunity of considering the same and shall
be supplied by the Company with sufficient information to enable it to make an
informed decision with respect thereto. Executed or true and correct copies of
any waiver or consent effected pursuant to the provisions of this Section 9
shall be delivered by the Company to each holder of outstanding Notes forthwith
following the date on which the same shall have been executed and delivered by
the bolder or holders of the requisite percentage of outstanding Notes, The
Company will not, directly or indirectly, pay or cause to be paid any
remuneration, whether by way of supplemental or additional interest, fee or
otherwise, to any holder of the Notes as consideration for or as an inducement
to the entering into by any bolder of the Notes of any waiver or amendment of
any of the terms and provisions of this Agreement unless such remuneration is

                                      -31-
<PAGE>

concurrently paid, on the same terms, ratably to each holder of the then
outstanding Notes. Any consent made by a holder of Notes that has transferred
or has agreed to transfer its Notes to the Company, any Subsidiary, or any
Affiliate thereof arid has provided or has agreed to provide such written
consent as a condition to such transfer shall be void and of no force and
effect except solely as to such holder, and any amendments effected or waivers
granted or to be effected or granted that would not have been or would not be so
effected or granted but for such consent (and the consents of all other holders
of Notes that were acquired under the same or similar conditions) shall be void
and of no force and effect retroactive to the date such amendment or waiver
initially took or takes effect, except solely as to such holder.

     9.3. Binding Effect. Any such amendment, consent or waiver shall apply
equally to all the holders of the Notes and shall be binding upon them, upon
each future holder of any Note and upon the Company whether or not such Note
shall have been marked to indicate such amendment, consent or waiver and whether
or not such holder approved of such amendment, consent or waiver. No such
amendment, consent or waiver shall extend to or affect any obligation not
expressly amended, consented to or waived or impair any right related thereto,

ss.10. FORM OF NOTES, REGISTRATION, TRANSFER, EXCHANGE AND REPLACEMENT

     10.1. Form of Notes. Each Note initially delivered under this Agreement
will be in the form of one fully registered Note in the form attached as Exhibit

at least $1,000,000 (or the remaining outstanding balance thereof, if less than
$1,000,000).

     10.2. Note Register. The Company shall cause to be kept at its principal
office a register (the "Note Register") for the registration and transfer of the

the Note Register. The Company may deem and treat the person in whose name a
Note is so registered as the holder and owner thereof for all purposes (subject
to the provisions of Section 2.5) and shall not be affected by any notice to the
contrary, until due presentment of such Note for registration of transfer as
provided in this Section 10.

     10.3. Issuance of New Notes upon Exchange or Transfer. Upon surrender for
exchange or registration of transfer of any Note at the office of the Company
designated for notices in accordance with Section 11.2, the Company shall
execute and deliver, at its expense, one or more new Notes of any authorized
denominations requested by the holder of the surrendered Note, each dated the
date to which interest has been paid on the Notes so surrendered (or, if no
interest has been paid, the date of such surrendered Note), but in the same
aggregate unpaid principal amount as such surrendered Note, and registered in
the name of such person or persons as shall be designated in writing by such
holder. Every Note surrendered for registration of transfer shall be duly
endorsed, or be accompanied by a written instrument of transfer duly executed,
by the holder of such Note or by his attorney duly authorized in writing.

of a bond of indemnity in such form and amount as shall be reasonably
satisfactory to the Company or in the event of such mutilation upon surrender
and cancellation of the Note, the Company, without charge to the holder thereof,
will make and deliver a new Note of like tenor in lieu of such lost, stolen,
destroyed or mutilated Note. If any such lost, stolen or destroyed Note is owned
by you or any other Institutional Holder, then the affidavit of an authorized
officer of such owner setting forth the fact of such loss, theft or destruction
and of its ownership of the Note at the time of such loss, theft or destruction
shall be accepted as satisfactory evidence thereof, arid no further indemnity
shall be required as a condition to the execution and delivery of a new Note,
other than a written agreement of such owner (in form reasonably satisfactory to
the Company) to indemnify the Company for any losses directly suffered by the
Company relating to the lost, stolen, destroyed or mutilated Note and the
issuance by the Company of a new Note.
