Dear Dr. Genoni,

I am writing to confirm our recent discussions about your joining our Company
and assisting us in developing market for existing products as well as those
now under development.

Effective September 1, you have been named Vice President - Marketing
reporting to me.  Your primary focus initially will be to help me develop a
functional marketing and business plan for the company.  Included in this task
will be the determination of where to locate our permanent North American
offices, identification of key potential target customers, and developing and
implementing strategies to sell our product range to them.  You will also be
responsible for revamping our web-site and web based sales.

In October, we intend to use the business plan as a selling tool to raise
additional financing for the company through an institutional private
placement.  You will assist me in this respect as required in making
presentations to potential investors.

We have initially identified the following key commercial sectors on which the
Company will concentrate its initial efforts:

1.  OEM for PFP, and CE based fax applications
2.  Long distance telephony resellers and large corporate users of
telecommunications
3.  Secured printing applications
4.  Government and other institutions requiring secure communications

Over the next few months we will be looking to hire specialists in each of
these fields to develop sales in their respective areas of expertise.  We will
work together in identifying candidates, and in developing strategies to
support our commercial endeavors in each segment.

As a "start-up" company, I do not believe it is necessary to try and
exhaustively define your job function.  Rather, it will evolve in accordance
with the direction our business takes through our joint efforts.

<PAGE>

Your compensation will be primarily success driven.  We have agreed on the
following elements:

1.  A monthly fee of Cdn. $7,500 paid each month in arrears.  No GST would
apply as ITI Nevada is a US corporation.  You will be responsible for your own
office overheads.  We will reimburse you reasonable out of pocket expenses
such as long distance calls, travel etc. upon submission of appropriate
documentation.  Please provide us a monthly invoice for your services and
expenses.

2.  You will be granted 30,00 share purchase options at US$1.50 per share.
These options will vest pro-rata temporis over a three year period unless the
Company changes control or is acquired in which case all unearned options will
vest immediately.  A separate agreement on the share options is being
forwarded to you.

3.  A success fee in accordance with your memo of September 11, a copy of
which is enclosed herewith.

It is understood that you will have the status of a private contractor and
will be responsible for your own withholding taxes, social security and other
contributions.

Either party may at anytime cancel this agreement by giving the other three
months written notice of termination.  In case of termination, the provisions
of the Confidentiality Agreement you previously signed will survive.

It is understood that in case of termination, any commissions due you for
sales initiated by you will continue to be honored in accordance with the
attached schedule.

I very much look forward to working with you, and ask that you sign and return
the enclosed copy of this letter confirming your acceptance of the terms
contained herein.

Sincerely yours,                        Read and accepted

vested will immediately vest.
