PROSPECTUS

                                  CATUITY INC.

                        1,048,480 SHARES OF COMMON STOCK

     We have prepared this prospectus to allow the selling stockholders to offer
for resale up to 1,048,480 shares of our common stock issued by us to the
selling stockholders in two private placements completed on September 1 and
September 19, 2005.

     The shares of common stock offered by this prospectus could be sold in
several ways, including in the open market or otherwise at prevailing market
prices at the time of sale, in privately negotiated transactions at prices
agreed upon by the parties or through any other means described under the
heading "Plan of Distribution" beginning on page 8. The selling stockholders may
elect to sell all, a portion of, or none of the shares of common stock offered
hereby. Our company is not selling any shares of common stock in this offering
and therefore we will not receive any proceeds from any sale of securities
offered by this prospectus. We are registering the shares of common stock
offered under this prospectus to satisfy registration rights that we granted to
the selling stockholders in connection with the purchase of the common stock by
the selling stockholders. We have agreed to pay for all expenses in connection
with the registration of the securities offered by this prospectus.


     Our common stock is quoted on the Nasdaq SmallCap Market under the symbol
"CTTY" and is traded on the Australian Stock Exchange under the symbol "CAT". On
November 25, 2005, the last sales price of our common stock as reported on the
Nasdaq SmallCap Market was $7.65 per share.


     No underwriter or any other person has been engaged to facilitate the sale
of the securities in this offering.

     INVESTING IN OUR COMMON STOCK INVOLVES A HIGH DEGREE OF RISK THAT IS
DESCRIBED IN THE "RISK FACTORS" SECTION BEGINNING ON PAGE 1 OF THIS PROSPECTUS.
WE URGE YOU TO CAREFULLY READ THE "RISK FACTORS" SECTION BEFORE YOU MAKE YOUR
INVESTMENT DECISION.

     NEITHER THE SECURITIES AND EXCHANGE COMMISSION NOR ANY STATE SECURITIES
COMMISSION HAS APPROVED OR DISAPPROVED OF THESE SECURITIES OR DETERMINED IF THIS
PROSPECTUS IS TRUTHFUL OR COMPLETE. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.

                SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This document includes "forward-looking" statements within the meaning of the
Private Securities Litigation Act of 1995. This Act provides a "safe harbor" for
forward-looking statements to encourage companies to provide prospective
information so long as they identify these statements as forward-looking and
provide meaningful cautionary statements identifying important factors that
could cause actual results to differ from the expected results. All statements
other than statements of historical fact made in this document are forward
looking. In some cases, they can be identified by terminology such as "may,"
"will," "should," "expect," "plan," "anticipate," "believe," "estimate,"
"predict," "potential," or "continue," the negative of such terms or other
comparable terminology. These statements are only predictions. Actual events or
results may differ materially. In evaluating these statements, you should
consider various factors that may cause actual results to differ materially from
any forward-looking statements.

     Although we believe that the expectations reflected in the forward-looking
statements are reasonable, we cannot guarantee our future results, levels of
activity, performance or achievement. Moreover, neither we nor any other person
assumes liability for the accuracy and completeness of the forward-looking
statements. Actual results may differ materially from those projected as a
result of certain risks and uncertainties, including but not limited to: changes
in currency exchange rates from period to period, inflation rates in the United
States and Australia, recession, and other external economic factors over which
the Company has no control; the timing and speed with which our major customers
and prospects execute their plans for the use of our loyalty software and
services; continued development of the Company's software products; competitive
product and pricing pressures; use of internally developed software
applications; patent and other litigation risks; the risk of key staff leaving
the Company; the risk that major customers of the Company's products and
services reduce their requirements or terminate their arrangements with the
Company; as well as other risks and uncertainties, including but not limited to
those detailed from time to time in the Company's Securities and Exchange
Commission filings. These forward-looking statements are made only as of the
date hereof, and the Company undertakes no obligation to update or revise the
forward-looking statements, whether as a result of new information, future
events or otherwise. We urge you not to unduly rely on forward-looking
statements contained or incorporated by reference in this prospectus.

                               PROSPECTUS SUMMARY

     This summary highlights information contained elsewhere in this prospectus.
This summary is not complete and may not contain all of the information that may
be important to you. We urge you to read the entire prospectus carefully,
including the "Risk Factors" section, and the additional documents incorporated
by reference herein, before making an investment decision.

                                  CATUITY INC.

     Catuity provides technology-based solutions to retailers that are designed
to increase the profit they receive from their customers at the Point of Sale
(POS). Today, the Company sells a hosted, ASP-based system that enables the
processing of member-based loyalty programs and which can deliver customized
discounts, promotions, rewards and points-based programs which are designed to
help retailers find, keep and profit from their best customers. The Company also
enables gift card solutions. In late 2004, the Company introduced the first
version of its new platform, the Catuity Advanced Loyalty System (CALS). The
system enables robust and highly customizable programs which work on a
retailer's payments terminals, Electronic Cash Register and on their internal
store networks. Catuity also offers IT services to retailers to support their
POS systems maintenance and custom development needs for both the deployment of
our technology solution and those of third parties which also touch the point of
sale.

     Our executive offices are located at 2711 E. Jefferson Avenue, Detroit,
Michigan 48207, and our telephone number is (313) 567-4348. We maintain a site
on the world wide web at the address http://www.catuity.com. The information on
our web site is not a part of this prospectus or incorporated by reference
herein.

     WE URGE YOU TO REFER TO THE SECTION ENTITLED "RISK FACTORS" FOR AN
EXPLANATION OF THE RISKS OF INVESTING IN OUR COMMON STOCK.

                               UPDATED INFORMATION

     On September 1, 2005, we closed on our acquisition of Loyalty Magic Pty Ltd
and our offering of shares in Australia and the United States for aggregate
proceeds of US$5,250,000. In those transactions, we sold a total of 443,480
shares to certain selling stockholders pursuant to certain Subscription
Agreements, in a private placement conducted in the United States, and we issued
335,000 shares to certain other of the selling stockholders as partial
consideration for the Loyalty Magic acquisition.

     On September 19, 2005, we closed on our offering of 270,000 shares in the
United States pursuant to certain Subscription Agreements, in a private
placement, for aggregate proceeds of US$2,025,000.

                                  RISK FACTORS

     We urge you to consider carefully all of the information set forth in this
prospectus and incorporated by reference in this prospectus. Please refer to
"Where You Can Find More Information" and "Incorporation by Reference." We urge
you to particularly evaluate the following risks before deciding to purchase the
common stock. Various statements in this prospectus (including some of the
following risk factors) and incorporated by reference in this prospectus
constitute forward-looking statements. Please refer to the section entitled
"Special Note Regarding Forward-Looking Statements."

     Any investment in our company will be subject to risks inherent to our
business. Before making an investment decision, you should carefully consider
the risks described below together with all of the other information included in
this prospectus. The risks and uncertainties described below are not the only
ones facing our company. Additional risks and uncertainties that we are not
aware of or focused on or that we currently deem immaterial may also impair our
business operations. This prospectus is qualified in its entirety by these risk
factors.


                                       1

     If any of the following risks actually occur, they could materially
adversely affect our business, financial condition, liquidity or results of
operations. In that case, the trading price of our common stock could decline
and you may lose all or part of your investment.

                          RISKS RELATED TO OUR BUSINESS

WE HAVE A HISTORY OF LOSSES AND ANTICIPATE FUTURE LOSSES.

     As of December 31, 2004, we had an accumulated deficit of $34,265,126. To
date, we have not achieved profitability. While management believes our
strategies will be successful, there can be no assurance that our business
strategies will be successful or that significant revenues or profitability will
be achieved. If we do achieve profitability, we cannot be certain that we can
sustain or increase profitability on an ongoing basis.

WE MAY BE ADVERSELY AFFECTED IF WE FAIL TO RETAIN KEY PERSONNEL AND ATTRACT NEW
QUALIFIED PERSONNEL.

     Our operations will depend on our ability to attract new key personnel and
retain existing key personnel. We have from time to time in the past
experienced, and we expect to experience in the future, difficulty in hiring and
retaining highly skilled employees with appropriate qualifications. If we are
unable to hire or retain key employees, our business, results of operations and
financial condition will be harmed.

WE WILL BE ADVERSELY AFFECTED IF OUR CALS PRODUCT DOES NOT ACHIEVE MARKET
ACCEPTANCE.

     We will be adversely affected if our new generation of software, the
Catuity Advanced Loyalty Systems ("CALS"), does not achieve market acceptance.
CALS had not been commercially deployed, and there can be no assurance that the
product will perform all the desired functions, or offer sufficient
price/performance benefits or meet the technical or other requirements of
customers. Despite testing of our product prior to its commercial release, there
can be no assurance that all performance errors or deficiencies have been
discovered and remedied, that additional errors or deficiencies will not occur,
or if they occur, that we will be able to correct such errors and deficiencies.

FAILURE TO OBTAIN CERTIFICATIONS IN A TIMELY MANNER

     To deploy our technology on behalf of a client, Catuity must install a
specialized application at the point of sale for a client. Because of the
diverse range of payment terminals, readers, electronic cash registers and
proprietary checkout systems used by merchants and retailers, Catuity must
certify its application to meet the standards of the independent manufacturers
of each model and series of terminals. Equally important, in many cases,
Catuity's POS application must be certified by the payments processor who
manages the transactional side of the business for merchants and retailers.
Catuity has been successful in previous efforts with market leaders including
Verifone, Hypercom and Schlumberger. However, we can make no assurance that the
Company will be able to obtain future certifications in a timely manner. If we
fail to obtain the necessary certifications, it could have a material adverse
impact us, including the loss of existing business, extended delays in closing
new business and/or the impairment of future revenues.

SALES ACTIVITIES WITH PROSPECTIVE CUSTOMERS MAY NOT GENERATE REVENUE FOR THE
COMPANY

     The success of our operations will be highly dependent on our ability to
generate revenue from current and future prospective customers. While management
believes that the Company will be successful in generating revenue from
prospective customers there can be no assurance of the level of revenue that
will be generated.


                                       2

                          RISKS RELATED TO OUR INDUSTRY

COMPETITION IN THE APPLICATION SOFTWARE INDUSTRY COULD HARM OUR BUSINESS.

     The application software industry is highly competitive, rapidly developing
and subject to constant innovation and change. Numerous other companies operate
incentive marketing programs using both electronic and paper based systems, both
for retail stores and the Internet. Many of these companies have significantly
longer operating histories, greater name recognition, larger customer bases and
greater financial, technical and marketing resources than we do.

Our competitors may respond more quickly than we can to changing technologies
and customer requirements. For example, these competitors may:

     -    conduct more extensive marketing campaigns to capture market share;

     -    provide more attractive incentive and pricing packages to customers;

     -    negotiate more favorable contracts with existing and potential
          employees and strategic partners;

     -    establish cooperative relationships among themselves or with third
          parties, including large Internet participants, to increase the
          ability of their products and services to address the needs of
          prospective customers;

     -    bundle their products with other software or hardware, including
          operating systems and browsers, in a manner that may discourage users
          from purchasing products offered by us;

     -    establish cooperative relationships with our current or potential
          competitors, thereby limiting our ability to sell our products through
          particular reseller channels; or

     -    more quickly develop new products and services or enhance existing
          products and services.

     Our ability, and the ability of our resellers, to compete effectively in
the market for application software for incentive and loyalty marketing programs
will depend upon a variety of factors, including our ability to provide high
quality products and services at prices generally competitive with, or lower
than, those charged by our competitors. There can be no assurance that we will
be able to compete successfully. Moreover, there can be no assurance that
certain of our competitors will not be better situated to negotiate contracts
with retailers and resellers that are more favorable than contracts we
negotiate. In addition, there can be no assurance that the competition from
existing or new competitors or a decrease in the rates charged for products and
services by our competitors will not materially and adversely affect us.

NEW TECHNOLOGIES COULD RENDER OUR PRODUCT OBSOLETE.

     The application software business is characterized by rapid technological
change, new product introduction and evolving industry standards. Advances in
applications software or the development of entirely new technologies to replace
existing applications software could render our product obsolete and
unmarketable. Our success will depend, in significant part, on our ability to
make timely and cost-effective enhancements and additions to our technology and
to introduce new products and services that meet customer demands. There can be
no assurance that we will be successful in developing new products, services and
enhancements. Delay in the introduction of new products, enhancements or
services, the inability to develop such new products, enhancements or services
or their failure to achieve market acceptance could have a material adverse
effect on us.


                                       3

WE MAY FACE RISKS RELATED TO THE STORAGE OR PROVISION OF INACCURATE OR
CONFIDENTIAL INFORMATION.

     It is possible that information provided through the use of our product or
information that is copied and stored by customers that have deployed our
product may contain errors. In such event, third parties could make claims
against us for losses incurred in reliance on such information. Although we
carry general liability insurance, our insurance may not cover potential claims
of this type or may not be adequate to indemnify us for all liability that may
be imposed. Any imposition of liability or legal defense expenses that is not
covered by insurance or that is in excess of insurance coverage could have a
material adverse effect on our business, financial condition and results of
operations.

     In addition, from time to time, persons may unlawfully obtain information
concerning a customer's or retailer's program by unlawfully utilizing access
numbers, passwords and personal identification numbers. No assurance can be
given that future losses due to claims by third parties for unauthorized use
will not be material. We maintain no reserves for such risks.

     There can be no assurance that our risk management practices will be
sufficient to protect us from unauthorized thefts of information that could have
a material adverse effect on us.

WE MAY BE SUBJECT TO PRODUCT LIABILITY CLAIMS FOR USE OR MISUSE OF OUR PRODUCT.

     Retailers rely, and will continue to rely, on our product in connection
with providing promotions that have a direct financial impact on their
businesses and their customers. Use or misuse of our product, whether due to
accident, employee fraud, or otherwise, may result in unintended or undesirable
consequences that could result in financial or other damages to our customers
and to our customers' customers. A product liability claim brought against us,
even if not successful, would likely be time consuming and costly and could have
a material adverse effect on us.

WE MAY FACE RISKS RELATED TO THE USE OF ELECTRONIC PAYMENT CARDS.

     Portions of our software may be integrated with or co-reside with a range
of third party payment and other software. For example, our product may be added
to existing or new electronic payment cards, either by the addition of software
to a chip or by using the payment card number as an identifier with our product.
Alternatively, a portion of the software comprising our product may be added to
existing or new payment devices, so that such software co-resides with payment
programs. On the Internet and in other environments, a portion of our software
may be integrated with a third party supplied e-commerce program. There can be
no assurances that such integration or co-residence will not adversely affect
the payment system, potentially giving rise to a claim that may have a material
adverse effect on our business, financial condition and results of operations.
In addition, if our customers experience problems with a payment system, it may
be difficult to determine if those problems originate from our product or other
products with which ours co-reside. Such difficulty may delay resolution of any
such problem and prove costly to us.

WE MAY BE AFFECTED BY POTENTIAL PRIVACY REGULATION.

     The Federal Trade Commission is considering the adoption of regulations
regarding the collection and use of personal information obtained from
individuals when accessing Internet sites. These regulations could restrict our
ability to provide demographic data to retailers. At the international level,
the European Union has adopted a directive that will impose restrictions on the
collection and use of personal data. These developments could have an adverse
effect on our business, results of operations and financial condition.

WE MAY FACE INCREASED GOVERNMENTAL REGULATION AND LEGAL UNCERTAINTIES.

     Catuity will enable or manage confidential customer information on behalf
of our clients. Recent high profile cases of customer information being
compromised have heightened concerns among our


                                       4

prospects, investors and state and federal legislators about the need to ensure
that the information of individuals be protected. Since Sept. 11, 2001,
regulation of public and non-public information has increased significantly.
Even though Catuity's customers generally seek written permission from loyalty
program participants to collect and use information on their shopping behavior,
the Company cannot ensure that its customers will comply with appropriate
regulations or industry best practices. The gift card industry also continues to
face regulatory, legislative and judicial scrutiny. At present, Attorney
Generals in at least 26 states in the U.S. have initiated lawsuits against high
profile gift card providers targeting their disclosure and management practices.
Proposed state and federal legislation, such as the Fair Gift Card Act, is
specifically directed at "escheatment", "breakage" and liability management
practices of card issuers. Broadly, this concerns both the level of required
disclosure to consumers about fees and charges associated with their accounts.
To manage these risks, Catuity takes appropriate and customary steps in our
client agreements and through our operational procedures. Catuity has no control
over the pricing, disclosure and management strategies of its clients and cannot
ensure that our clients will comply with appropriate regulations or industry
best practices. To the extent that Catuity's customers face regulatory,
legislative or judicial action, the Company could be made a party to those
actions. These could materially and adversely affect us.

WE MAY FACE INTELLECTUAL PROPERTY CHALLENGES.

     Our success and ability to compete are substantially dependent on our
proprietary technology and trademarks, which we attempt to protect through a
combination of patent, copyrights, trade secret and trademark laws as well as
confidentiality procedures and contractual provisions. However, any steps we
take to protect our intellectual property may be inadequate, time consuming and
expensive, and there can be no assurance that the steps taken by us will prevent
misappropriation of our technology, particularly in foreign countries where the
laws may not protect our proprietary rights as fully as do the laws of the
United States. In addition, we may infringe upon the intellectual property
rights of third parties, including third party rights in patents that have not
yet been issued. We expect that third-party infringement claims involving
Internet technologies and software products will increase. Any claims regarding
the rights of third parties, with or without merit, could be time consuming to
defend, result in costly litigation, divert management's attention and
resources, cause product shipment delays or require us to enter into royalty or
licensing agreements. Such royalty or licensing agreements, if required, may not
be available on terms favorable to us, if at all. We have agreed, and may agree
in the future, to indemnify certain of our customers against claims that our
products infringe the intellectual property rights of others. We could incur
substantial costs in defending our sellers and our customers against
infringement claims. A successful claim of product infringement against us and
our failure or inability to license the infringed or similar technology could
have a material adverse effect on our business, financial condition and results
of operations.

     We have applied for patents in relation to the method of operation of
incentive marketing programs using electronic means. We cannot assure you that
our patent applications will be approved. Moreover, even if approved, they may
not provide us with any competitive advantages or may be challenged by third
parties. In recent times a number of patents have been granted in this area.
Although we are not aware of any issued patent that our product would infringe,
legal standards relating to the validity, enforceability and scope of
intellectual property rights in Internet-related industries and use of
electronic data for granting of benefits and rewards are uncertain and still
evolving, and the future viability or value of any of our intellectual property
rights is uncertain.

                           CORPORATE AND MARKET RISKS

OUR TRADING VOLUME MAY BE LOW AND OUR SHARE PRICE MAY BE VOLATILE.

     We are currently listed on two exchanges, the ASX, in Australia, and the
Nasdaq Small Cap Market, in the United States. There can be no assurance that an
adequate volume of trading in our shares will be achieved and maintained, on
Nasdaq or the ASX, in order to provide liquidity for our investors. Trading in
Catuity shares on Nasdaq and the ASX averaged 1,937 shares per day in 2004.


                                       5

     The market price of our common stock may fluctuate significantly in
response to the following factors, some of which are beyond our control:

     -    variations in actual or anticipated quarterly or annual operating
          results;

     -    changes in financial estimates by securities analysts;

     -    changes in market valuations of loyalty software & service companies;

     -    announcements by us of significant contracts, reseller arrangements,
          strategic partnerships, joint ventures or capital commitments;

     -    additions or departures of key personnel;

     -    sales of common stock or termination of stock transfer restrictions;
          and

     -    fluctuations in stock market price and volume, which are particularly
          common among securities of small technology companies.

     The market prices and volumes of the common stock of many publicly held
technology based companies have in the past been, and can in the future be
expected to be, especially volatile, which could cause the market price of our
common stock to fall for reasons not necessarily related to our business,
results of operations or financial condition. The market price of our stock also
might decline in reaction to events that affect other companies in our industry
even if these events do not directly affect us. Accordingly, you may not be able
to resell your shares of common stock at or above the price you paid. In the
past, following a period of volatility in the market price of a company's
securities, securities class action litigation often has been instituted against
such a company. Any such litigation could result in substantial costs and a
diversion of management's attention and our resources.

WE MAY BE SUBJECT TO ARBITRAGE RISKS.

     Investors may seek to profit by exploiting the difference, if any, in the
price of our stock on the ASX and Nasdaq. Such arbitraging activities could
cause our stock price in the market with the higher value to decrease to the
price set by the market with the lower value.

COMPLYING WITH NASDAQ'S CONTINUED LISTING REQUIREMENTS


     We have experienced, difficulty maintaining all of Nasdaq's continued
listing requirements in the past, due to the small size of our Company. Our
recently completed stock offerings have provided us with adequate capital to
meet the stockholders' equity requirements of Nasdaq's continued listing
requirements for the foreseeable future. The requirements for continued listing
on the Nasdaq SmallCap Market are as follows:


     (1) either (a) stockholders' equity of $2,500,000, (b) net income in the
most recently completed fiscal year or in two of the last three years of
$500,000, or (c) market capitalization of $35,000,000;

     (2) a public float of 500,000 shares;

     (3) a market value of public float of $1,000,000;

     (4) a minimum bid price of $1.00 per share;

     (5) at least two market makers;


                                       6

     (6) at least 300 round lot stockholders; and

     (7) compliance with Nasdaq corporate governance rules.

CERTAIN DELAWARE ANTI-TAKEOVER PROVISIONS MAY PRODUCE RESULTS DISFAVORED BY OUR
STOCKHOLDERS.

     Provisions of Delaware law could make it more difficult for a third party
to acquire control of us without the consent of our board of directors, even if
our stockholders favored such a change. We are subject to Section 203 of the
Delaware General Corporation Law, which, subject to certain exceptions,
prohibits a publicly held Delaware corporation from engaging in any "business
combination" with any "interested stockholder" for a period of three years
following the date that such stockholder became an interested stockholder,
unless:

     -    prior to such date, the board of directors approved either the
          business combination or the transaction that resulted in the
          stockholder becoming an interested stockholder;

     -    upon consummation of the transaction that resulted in the stockholder
          becoming an interested stockholder, the interested stockholder owned
          at least 85% of our voting stock outstanding at the time the
          transaction commenced; and

     -    on or subsequent to such date, the business combination is approved by
          the board of directors and authorized at an annual or special meeting
          of stockholders, and not by written consent, by the affirmative vote
          of at least 66% of the outstanding voting stock that is not owned by
          the interested stockholder.

     Section 203 defines "business combination" to include:

     -    any merger or consolidation involving the corporation and the
          interested stockholder;

     -    any sale, transfer, pledge or other disposition of 10% or more of our
          assets involving the interested stockholder;

     -    subject to certain exceptions, any transaction that results in the
          issuance or transfer by us of any of our stock to the interested
          stockholder;

     -    any transaction involving us that has the effect of increasing the
          proportionate share of the stock of any class or series beneficially
          owned by the interested stockholder; and

     -    the receipt by the "interested stockholder" of the benefit of any
          loans, advances, guarantees, pledges or other financial benefits
          provided by us or through the corporation.

     In general, Section 203 defines an interested stockholder as an entity or
person beneficially owning 15% or more of our outstanding voting stock and any
entity or person affiliated with or controlling or controlled by such entity or
person.

CHANGES IN, OR INTERPRETATIONS OF, ACCOUNTING RULES AND REGULATIONS, SUCH AS
EXPENSING OF STOCK OPTIONS, COULD RESULT IN UNFAVORABLE ACCOUNTING CHARGES

     We prepare our consolidated financial statements in conformity with
accounting principles generally accepted in the United States of America. These
principles are subject to interpretation by the SEC and various bodies formed to
interpret and create appropriate accounting policies. A change in these policies
can have a significant effect on our reported results and may even retroactively
affect previously reported transactions. In particular, the FASB recently
enacted SFAS No. 123 (revised 2004), "Share-Based


                                       7

Payment" ("SFAS 123(R)") which we will adopt effective the first quarter of
2006. As a result, because SFAS 123(R) requires the expensing of stock options,
it will have an adverse effect on our reported financial results. However, we
have not yet assessed the level of impact to be able to quantify the adverse
effect.

                                USE OF PROCEEDS

     The selling stockholders will receive all of the proceeds from the resale
of the shares of common stock offered hereby. We will not receive any proceeds
from the resale of the shares of common stock.

                              SELLING STOCKHOLDERS

     The Shares being offered by the selling stockholders were issued pursuant
to the Subscription Agreements and the Loyalty Magic purchase agreement. We are
registering the Shares in order to permit the selling stockholders to offer the
shares for resale from time to time. Except for the ownership of the Common
Shares, and with the exception of the stockholders who are on Catuity's Board of
Directors (Clifford Chapman (Chaproc Capital LLC), Donald C. Campion, Alexander
S. Dawson and Glomore Pty Ltd., the family trust for Alexander S. Dawson, and
Alfred H. Racine), the selling stockholders have not had any material
relationship with us within the past three years.


     The table below lists the selling stockholders and other information
regarding the beneficial ownership of the Shares by each of the selling
stockholders. The second column lists the number of Shares beneficially owned by
each selling stockholder, as of November 29, 2005.


     The third column lists the Shares being offered by this prospectus by the
selling stockholders.

     In accordance with the terms of registration rights agreements with the
selling stockholders, this prospectus generally covers the resale of all of the
Shares issued pursuant to the subscription agreements. The fourth column assumes
the sale of all of the shares offered by the selling stockholders pursuant to
this prospectus.

     The selling stockholders may sell all, some or none of their shares in this
offering. See "Plan of Distribution."

     master-feeder structure. The Fund's investment manager is DKR Oasis
     Management Company LP (the "Investment Manager"). Pursuant to an investment
     management agreement among the Fund, the feeder funds and the Investment
     Manager, the Investment Manager has the authority to do any and all acts on

     responsibility for trading with respect to the Fund. Mr. Fischer disclaims
     beneficial ownership of the shares.

(3)  Mr. Stewart Flink is a registered broker-dealer with Dillon Capital.
     Crestview Capital Master LLC acquired the shares to be placed in the fund.
     They were not purchased by Mr. Flink in the ordinary course of business as
     a broker-dealer.

(4)  With the exception of Mr. Stewart Flink, as noted in footnote 3 above, none
     of the selling stockholders is, or is an affiliate of, a registered
     broker-dealer. At the time of acquisition, no selling stockholder had any
     agreements, understandings, or arrangements with any other persons, either
     directly or indirectly, to dispose of the securities.


                              PLAN OF DISTRIBUTION

     We are registering the Shares to permit the resale of these Shares by the
holders from time to time after the date of this prospectus. We will not receive
any of the proceeds from the sale by the selling stockholders of the Shares. We
will bear all fees and expenses incident to our obligation to register the
Shares.


                                       9

     The selling stockholders may sell all or a portion of the Shares
beneficially owned by them and offered hereby from time to time directly or
through one or more underwriters, broker-dealers or agents. If the Shares are
sold through underwriters or broker-dealers, the selling stockholders will be
responsible for underwriting discounts or commissions or agent's commissions.
The Shares may be sold in one or more transactions at fixed prices, at
prevailing market prices at the time of the sale, at varying prices determined
at the time of sale, or at negotiated prices. These sales may be effected in
transactions, which may involve crosses or block transactions,

- -    on any national securities exchange or quotation service on which the
     securities may be listed or quoted at the time of sale;

- -    in the over-the-counter market;

- -    in transactions otherwise than on these exchanges or systems or in the
     over-the-counter market;

- -    through the writing of options, whether such options are listed on an
     options exchange or otherwise;

- -    ordinary brokerage transactions and transactions in which the broker-dealer
     solicits purchasers;

- -    block trades in which the broker-dealer will attempt to sell the shares as
     agent but may position and resell a portion of the block as principal to
     facilitate the transaction;

- -    purchases by a broker-dealer as principal and resale by the broker-dealer
     for its account;

- -    an exchange distribution in accordance with the rules of the applicable
     exchange;

- -    privately negotiated transactions;

- -    short sales;

- -    sales pursuant to Rule 144;

- -    broker-dealers may agree with the selling securityholders to sell a
     specified number of such shares at a stipulated price per share;

- -    a combination of any such methods of sale; and

- -    any other method permitted pursuant to applicable law.

     If the selling stockholders effect such transactions by selling Shares to
or through underwriters, broker-dealers or agents, such underwriters,
broker-dealers or agents may receive commissions in the form of discounts,
concessions or commissions from the selling stockholders or commissions from
purchasers of the Shares for whom they may act as agent or to whom they may sell
as principal (which discounts, concessions or commissions as to particular
underwriters, broker-dealers or agents may be in excess of those customary in
the types of transactions involved). In connection with sales of the Shares or
otherwise, the selling stockholders may enter into hedging transactions with
broker-dealers, which may in turn engage in short sales of the Shares in the
course of hedging in positions they assume. The selling stockholders may also
sell Shares short and deliver Shares covered by this prospectus to close out
short positions and to return borrowed shares in connection with such short
sales. The selling stockholders may also loan or pledge Shares to broker-dealers
that in turn may sell such shares.

     The selling stockholders may pledge or grant a security interest in some or
all of the convertible notes, warrants or Shares owned by them and, if they
default in the performance of their secured obligations, the pledgees or secured
parties may offer and sell the Shares from time to time pursuant to this


                                    10

prospectus or any amendment to this prospectus under Rule 424(b)(3) or other
applicable provision of the Securities Act of 1933, as amended, amending, if
necessary, the list of selling stockholders to include the pledgee, transferee
or other successors in interest as selling stockholders under this prospectus.
The selling stockholders also may transfer and donate the Shares in other
circumstances in which case the transferees, donees, pledgees or other
successors in interest will be the selling beneficial owners for purposes of
this prospectus.

     The selling stockholders and any broker-dealer participating in the
distribution of the Shares may be deemed to be "underwriters" within the meaning
of the Securities Act, and any commission paid, or any discounts or concessions
allowed to, any such broker-dealer may be deemed to be underwriting commissions
or discounts under the Securities Act. At the time a particular offering of the
Shares is made, a prospectus supplement, if required, will be distributed which
will set forth the aggregate amount of Shares being offered and the terms of the
offering, including the name or names of any broker-dealers or agents, any
discounts, commissions and other terms constituting compensation from the
selling stockholders and any discounts, commissions or concessions allowed or
reallowed or paid to broker-dealers.

     Under the securities laws of some states, the Shares may be sold in such
states only through registered or licensed brokers or dealers. In addition, in
some states the Shares may not be sold unless such shares have been registered
or qualified for sale in such state or an exemption from registration or
qualification is available and is complied with.

     There can be no assurance that any selling stockholder will sell any or all
of the Shares registered pursuant to the shelf registration statement, of which
this prospectus forms a part.

     The selling stockholders and any other person participating in such
distribution will be subject to applicable provisions of the Securities Exchange
Act of 1934, as amended, and the rules and regulations thereunder, including,
without limitation, Regulation M of the Exchange Act, which may limit the timing
of purchases and sales of any of the Shares by the selling stockholders and any
other participating person. Regulation M may also restrict the ability of any
person engaged in the distribution of the Shares to engage in market-making
activities with respect to the Shares. All of the foregoing may affect the
marketability of the Shares and the ability of any person or entity to engage in
market-making activities with respect to the Shares.

     We will pay all expenses of the registration of the Shares pursuant to the
registration rights agreement, estimated to be $20,000 in total, including,
without limitation, Securities and Exchange Commission filing fees and expenses
of compliance with state securities or "blue sky" laws; provided, however, that
a selling stockholder will pay all underwriting discounts and selling
commissions, if any. We will indemnify the selling stockholders against
liabilities, including some liabilities under the Securities Act, in accordance
with the registration rights agreements, or the selling stockholders will be
entitled to contribution. We may be indemnified by the selling stockholders
against civil liabilities, including liabilities under the Securities Act, that
may arise from any written information furnished to us by the selling
stockholder specifically for use in this prospectus, in accordance with the
related registration rights agreements, or we may be entitled to contribution.

     Once sold under the shelf registration statement, of which this prospectus
forms a part, the Shares will be freely tradable in the hands of persons other
than our affiliates.

     Our common stock is quoted on the Nasdaq SmallCap Market under the symbol
"CTTY."

                                  LEGAL MATTERS

     The validity of the common stock offered hereby will be passed upon by

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Subsection (a) of Section 145 of the General Corporation Law of the State
of Delaware empowers a corporation to indemnify any person who was or is a party
or is threatened to be made a party to any threatened, pending or completed
action, suit or proceeding whether civil, criminal, administrative or
investigative (other than an action by or in the right of the corporation) by
reason of the fact that he is or was a director, officer, employee or agent of
the corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by him in connection with such action, suit or proceeding if he acted
in good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the corporation, and, with respect to any criminal action
or proceeding, had no reasonable cause to believe his conduct was unlawful.

     Subsection (b) of Section 145 empowers a corporation to indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that such
person acted in any of the capacities set forth above, against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection with the defense or settlement of such action or suit if he acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the corporation, except that no indemnification may be made in
respect to any claim, issue or matter as to which such person shall have been
adjudged to be liable to the corporation unless and only to the extent that the
Court of Chancery or the court in which such action or suit was brought shall
determine upon application that, despite the adjudication of liability but in
view of all the circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses which the Court of Chancery or such
other court shall deem proper.

     Section 145 further provides that to the extent a director or officer of a
corporation has been successful on the merits or otherwise in the defense of any
such action, suit or proceeding referred to in subsections (a) and (b) of
Section 145 or in the defense of any claim, issue or matter therein, he shall be
indemnified against expenses (including attorneys' fees) actually and reasonably
incurred by him in connection therewith; that the indemnification provided for
by Section 145 shall not be deemed exclusive of any other rights to which the
indemnified party may be entitled; that indemnification provided by Section 145
shall, unless otherwise provided when authorized or ratified, continue as to a
person who has ceased to be a director, officer, employee or agent and shall
inure to the benefit of such person's heirs, executors and administrators; and
empowers the corporation to purchase and maintain insurance on behalf of a
director or officer of the corporation against any liability asserted against
him and incurred by him in any such capacity, or arising out of his status as
such, whether or not the corporation would have the power to indemnify him
against such liabilities under Section 145.


                                      II-1


     Section 102(b)(7) of the General Corporation Law of the State of Delaware
provides that a certificate of incorporation may contain a provision eliminating
or limiting the personal liability of a director to the corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director,
provided that such provision shall not eliminate or limit the liability of the
director (i) for any breach of the director's duty of loyalty to the corporation
or its stockholders, (ii) for acts or omissions not in good faith or which
involve intentional misconduct or a knowing violation of law, (iii) under
Section 174 of the Delaware General Corporation Law, or (iv) for any transaction
from which the director derived an improper personal benefit.

     Article Sixth of our certificate of incorporation, as amended, provides
that, to the fullest extent permitted by the Delaware General Corporation Law or
any other applicable laws presently or hereafter in effect, no director shall be
personally liable to Catuity or our stockholders for or with respect to any acts
or omissions in the performance of his or her duties as a director of Catuity.
Any repeal or modification of Article Sixth shall not adversely affect any right
or protection of a Catuity director existing immediately prior to such repeal or
modification.

     We have entered into indemnification agreements with certain of our
directors and executive officers. We also maintain officers' and directors'
liability insurance.

ITEM 17. UNDERTAKINGS

     (a)  The undersigned registrant hereby undertakes:

     (1)  To file, during any period in which offers or sales are being made, a
          post-effective amendment to this registration statement:

          (i)  To include any prospectus required by Section 10(a)(3) of the
               Securities Act of 1933;

          (ii) To reflect in the prospectus any facts or events arising after
               the effective date of the registration statement (or the most
               recent post-effective amendment thereof) which, individually or
               in the aggregate, represent a fundamental change in the
               information set forth in the registration statement.
               Notwithstanding the foregoing, any increase or decrease in volume
               of securities offered (if the total


                                      II-2


               dollar value of securities offered would not exceed that which
               was registered) and any deviation from the low or high end of the
               estimated maximum offering range may be reflected in the form of
               prospectus filed with the Commission pursuant to Rule 424(b) if,
               in the aggregate, the changes in volume and price represent no
               more than a 20 percent change in the maximum aggregate offering
               price set forth in the "Calculation of Registration Fee" table in
               the effective registration statement; and

          (iii) To include any material information with respect to the plan of
               distribution not previously disclosed in the registration
               statement or any material change to such information in the
               registration statement;

               provided, however, that paragraphs (1)(i) and (1)(ii) do not
               apply if the information required to be included in a
               post-effective amendment by those paragraphs is contained in
               periodic reports filed with or furnished to the Commission by the
               registrant pursuant to Section 13 or 15(d) of the Securities
               Exchange Act of 1934 that are incorporated by reference in the
               registration statement.

     (2)  That, for the purpose of determining any liability under the
          Securities Act of 1933, each such post-effective amendment shall be
          deemed to be a new registration statement relating to the securities
          offered therein, and the offering of such securities at that time
          shall be deemed to be the initial bona fide offering thereof.

     (3)  To remove from registration by means of a post-effective amendment any
          of the securities being registered which remain unsold at the
          termination of the offering.

     (b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

     (c) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the SEC such indemnification is against
public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than a payment by the registrant of expenses incurred or paid
by a director, officer or controlling person of the registrant in the successful
defense of any action, suit or proceeding) is asserted by such director, officer
or controlling person in connection with the securities being registered, the
registrant will, unless in the opinion if its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.


                                      II-3

                                   SIGNATURES


     Pursuant to the requirements of the Securities Act of 1933, the registrant
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form S-3 and has duly caused this registration
statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in Detroit, Michigan, on November 29, 2005.
