Re: Price Query


Dear Mr. Smythe,

Catuity is in receipt of your Price Query letter dated 9 September 2003. For
your, and our shareholders', convenience the Company has repeated each of your
queries and then provided its response directly beneath it.

     1.  Is the Company aware of any information concerning it that has not been
         announced which, if known, could be an explanation for recent trading
         in the securities of the Company?

         No, the Company is not aware of any information that has not been
         previously announced to the market.

         In answering this question, please comment specifically on:

         1.1      The likely impact of the Patents on the price or value of the
                  Company's securities.

         It is difficult to estimate if the patents that were recently issued to
         the Company have had any impact in the trading price or volume of the
         Company's stock. As part of the Company's business strategy Catuity
         continues to develop and strives to protect its intellectual property.
         Catuity has sought, and will continue to file applications for, patents
         in order to protect its intellectual property and to defer others from
         attempting to use their patents in a manner that would have a negative
         impact on the growth of the smart card - loyalty market.

         1.2      The status of the deployment of the Company's software by
                  Target Corporation, with reference in particular to the
                  following extract from the fourth page of the Company's 2002
                  Annual Report and 10-K (released to ASX on 14 April 2003),
                  under the heading of "Catuity's Accomplishments":

Target Corporation became Catuity's largest merchant customer. In 2002, Catuity
signed a three-year license agreement with Target Corporation, the second
largest discount retailer in the U.S, to provide our software to their
integrated payment system. Full deployment of this software is expected to be
complete by the third quarter of 2003.

         The Company does not have additional information regarding its
         relationship with Target Corporation to announce. The information below
         is provided as a recap of information already made public regarding
         Catuity's agreements with Visa and Target and the status of the Target
         program:

         Catuity has two contracts associated with the smart Visa Rewards
         Program. The first is with Visa USA. Visa licenses our software and
         pays us for smart Visa cards registered to our system that are active
         in their loyalty program. Visa paid Catuity for a significant number of
         licenses to our system in late 2001 and in 2002. Visa's payments for
         licenses were recognized as license revenue, and commented on, in the






         Company's first quarter 2003 financial report to its shareholders that
         was filed with the U.S. Securities and Exchange Commission and with the
         ASX.

         The second contract we have in the smart Visa Rewards Program is with
         Target Corporation. In 2002, Target paid Catuity a license fee to put
         our software on their electronic cash registers. The Company recognized
         this payment as license revenue in its second quarter 2003 financial
         report to its shareholders that was filed with the U.S. Securities and
         Exchange Commission and with the ASX. Under its agreement with Catuity,
         Target is not obligated to, and does not, provide Catuity with updates
         as to its status or progress in completing the national roll-out of our
         software or their specific marketing plans as to how they plan to use
         and promote it. In their second quarter financial analyst meeting on,
         or about, August 22, 2003, Target reported they had been installing the
         (Catuity) loyalty software on their cash registers during the summer
         months (in the U.S.) and had recently completed this task. Target also
         reported that they had begun a pilot of the system in July 2003.
         Target's web site contains information that, as part of the pilot, they
         are issuing smart coupons to customers who have a Target Visa card via
         the web and through in store kiosks and redeeming them at the cash
         register.

         Catuity has no further knowledge or information about the status of
         Target's roll-out or plans.

2.       If the answer to question 1 is yes, can an announcement be made
         immediately? If not, why not and when is it expected that an
         announcement will be made?

         Not applicable.

         Please note, if the answer to question 1 is yes and an announcement
         cannot be made immediately, you need to contact us to discuss this and
         you need to consider a trading halt (see below).

         Not applicable

3.       Is there any other explanation that the Company may have for the price
         change and increase in volume in the securities of the Company?

         The Company is not aware of any other information, facts or rumors that
         could be affecting its shares.

4.       Please confirm that the Company is in compliance with the listing rules
         and, in particular, listing rule 3.1.

         Catuity confirms that it is in compliance with the ASX Listing Rules
         and, in particular, Listing Rule 3.1.


Sincerely,

/s/ John H. Lowry
