                         Amendment to Stock Option Plan

On March 27, 2001 the Board of Directors of Catuity, Inc. approved an amendment
to Section (4), "Option Pool; Shares Reserved for Options" of the Company's
Stock Option Plan. This amendment increased the available number of shares in
the plan from 750,000 to 950,000 in order to ensure that a sufficient number of
shares would be available to meet the overall goals and objectives of the
employee plan for the next few years. At the Annual Shareholders Meeting, held
on May 24, 2001 in Sydney, Australia, the shareholders approved the amendment
for the increase.<PAGE>

                              TERMS AND CONDITIONS

1.       DEFINITIONS

         a. Confidential Information means any proprietary information,
cardholder information, merchant information, technical data, trade secrets or
know-how, research, experiments, inventions, processes, formulas, designs,
drawings, products, services, plans, customers, markets, finances, equipment,
card plastics or plates, software, source code, hardware configuration, or other
information disclosed by Visa, its Member financial institutions or other
service providers, in writing, orally, on tape or disk, or by drawings or
inspection of parts or equipment, and includes the results of services under
this Agreement, the Deliverables and any other information that reasonably
should be understood to be confidential. It includes Work Product and
Deliverables, which are hereby deemed to be the confidential information of
Visa. It does not mean information (a) already known by Seller at the time it is
disclosed as shown by written records; (b) publicly known without breach of this
Agreement; (c) received from a third party authorized to disclose it without
restriction; (d) independently developed by Seller without use of the
Confidential Information; or (e) required by law, regulation or valid court or
government order to be disclosed, if Seller first notifies Visa, so Visa may
seek a protective order.

         b. Deliverables mean items Seller personnel develop or provide to Visa
under any Exhibit to this Agreement, including all Work Product.

         [unused definition deleted]

         c. Work Product means improvements, inventions, developments,

enhancing or maintaining delivered software; and trade secrets; as well as all
their derivatives and modifications that Seller personnel make, conceive or
reduce to practice, solely or with others, while performing services in
connection with the Deliverables.

2. PERFORMANCE & COMPENSATION. Unless Visa agrees that a contractor of Seller
meets independent contractor requirements, Seller shall not provide any such
worker to perform services for Visa. This Agreement is for the personal services
of Seller and its personnel. Substitute performance for those personnel is not
acceptable without prior written consent by Visa. Visa agrees to pay Seller the
compensation set forth in a Project Description Exhibit, including pre-approved
expenses, unless the parties have agreed that Seller will include such expenses
in its fee. Seller will provide specified reports upon Visa's request. Visa
shall not be responsible for fees or expenses beyond those quoted on the Project
Description Exhibit.

3. TERMINATION. Either party may terminate this Agreement upon thirty (30) days'
prior written notice. If termination is for breach, the breaching party shall
have thirty (30) days to cure such breach. Termination shall be effective
without further notice at the end of such period if the breach has not been
cured. Visa may order Seller to immediately cease performance to prevent loss
from failure of its

<PAGE>

personnel to keep Confidential Information secure, their gross misconduct, or
Seller's insolvency .Visa may request Seller to immediately remove specific
Seller personnel from an assignment. Seller shall have ten (10) business days to
find substitute personnel acceptable to Visa. If Seller cannot provide a
suitable replacement within ten (10) business days, Visa may terminate the
relevant Exhibit or this Agreement without further obligation to Seller. Upon
termination, Visa shall pay Seller prorated fees and expenses for work
completed. Each party's duties on ownership of Work Product, confidentiality,
indemnification and warranties shall survive termination of this Agreement or
any Exhibit.

4. CONFIDENTIALITY. Seller shall use Visa's confidential information only for
the purposes of this Agreement, and shall take all reasonable precautions to
prevent unauthorized disclosure or use of it. Seller shall not make any press
release or other public disclosure of confidential information or performance of
services for Visa without prior written consent of Visa. Seller will hold all
confidential or proprietary information from third parties in the strictest
confidence, and shall use or disclose it only for performance of services
hereunder if consistent with the third party's agreement for its use. Upon
termination of this Agreement or upon demand, Seller promptly shall return to
Visa all property and confidential and proprietary information of Visa and of
third parties provided by Visa. If agreed, a Certification of Destruction may be
provided instead, with sufficient detail on items destroyed, destruction date,
and assurance that all copies also were destroyed.

5. SECURITY. Visa reserves the right to deny access to its premises, information
and systems to Seller or its personnel at any time for reasonable cause. For
access to sensitive data or systems or a Visa security badge, Seller personnel
will be subject to a background investigation, including criminal history and
consumer credit reports. Seller shall obtain its personnel's consent to such
security checks. Seller personnel shall comport themselves at all times
according to generally accepted standards of professional conduct, and according
to the Vendor Guidelines attached as Attachment 2 to the Agreement and are
incorporated herein by reference.

6. PROPRIETARY RIGHTS IN WORK PRODUCT, DELIVERABLES AND DATA

         a. Nothing contained herein shall give Visa any ownership rights in any
materials or information contained in the Deliverables that was developed or
acquired by Seller prior to the performance of the services under the Exhibit
governing the Deliverables, or that is licensed by Seller from any third party,
provided that Seller lists such retained materials and information under the
Ownership Rights section of the Project Description and grants Visa a license to
such retained materials and information adequate to permit the exercise of the
rights described in subsection (c) below.

         b. Excluding such retained materials and information, Seller grants to
Visa all rights to the Work Product and Deliverables, including complete,
unconditional and world- wide ownership of all intellectual property rights in
any draft or final version of material. Seller agrees to assist Visa, at Visa's
expense, in securing such worldwide rights and any intellectual property rights
relating thereto, including disclosure of all pertinent information and data and
execution of all documents needed. For copyrightable works not deemed to be
Work-Made-For-Hire, Seller shall assign such copyright to Visa and shall execute
all documents needed to evidence such assignment.

         c. Notwithstanding anything to the contrary in this Agreement, Visa
shall have the right to use and disclose all Deliverables from Seller in the
normal course of business, including use for evaluation, development and
marketing of products and services by Visa. In addition, upon transfer of the
Deliverables, Seller hereby waives all right to attribution or limitation on
subsequent use or modification.

services on Visa's premises.

writing, neither a party nor its personnel shall solicit for employment, hire or
engage in any capacity any employee of the other party. Visa shall have no

Deliverables or Work Product to a third party that would be inconsistent with
the rights granted to Visa under this Agreement.

this Agreement and performance of services hereunder does not contravene the
terms of any agreement with a third party.

         c. Inducements. Seller warrants that its personnel have not provided
and shall not provide any gift, gratuity, service, or other inducement to any
Visa employee or agency involved in retaining Seller's services for this
Agreement.

and shall restrict access to them solely to those Visa employees with a need to
know.

maintained by Visa shall be excess to and not contribute to Seller's insurance.
Every policy required under this Section shall contain the following clause: "No
reduction, cancellation or expiration of this policy shall become effective
until thirty (30) days from the date written notice is actually received by
Visa." Seller and its personnel shall not undertake any services until all

material revision of its coverage. Within thirty (30) days of execution of this

confirming such coverage to Visa, Attn: Business Affairs, P.O. Box 8999, M/S:
Ml-10B, San Francisco, CA 94128-8999. Fulfillment of obligations to procure

business hours throughout the term of this Agreement and for six (6) months
thereafter to perform audits of Seller's facilities, operations and records on

Seller also shall provide Visa or its designated agent during normal business
hours with books, records and supporting documentation adequate to evaluate
Seller's performance.

consent. Visa shall not be liable for Seller's debts, obligations or
liabilities, including without limitation Seller's obligation to withhold social

                           STANDARDS OF VENDOR CONDUCT

The following guidelines should be followed by all vendors, including vendors
working on behalf of Visa while at Visa offices, traveling on behalf of Visa, or
performing work on behalf of Visa outside of Visa offices. These guidelines are
intended to clarify the most common questions about the extent of vendor
involvement in daily Visa events.

OFFICE PRIVILEGES: Generally vendors will perform their services on behalf of
Visa at their own Seller's office. Office accommodations may be provided by Visa
only when necessary for security reasons or because the use of proprietary
equipment or programs is required. If Visa does provide office accommodations,
vendors may be asked to move to different locations within Visa at any time.

Office amenities such as coffee bars, restrooms, and the cafeteria are available
to guests, including vendors, with the exception of particular occasions when
the cafeteria or a similar area has been reserved for employee functions.

Secretarial services may be made available to vendors for the purpose of
conducting Visa business only when dealing with secured or proprietary
materials. Guidelines for use of secretarial services may be established by the
vendor's Visa project supervisor .

Telephone service may be made available to vendors for the purpose of conducting
Visa business only when the vendor is required to perform services on site to
work with secured or proprietary materials. Personal telephone calls or calls
unrelated to Visa business (e.g., to other clients) must be restricted to a
minimum, and in no case should a vendor ask a secretary or receptionist to
handle personal telephone calls. Long- distance personal calls should not be
made from a Visa telephone except with the vendor's credit/calling card.
Additional telephone guidelines may be established by the vendor's Visa project
supervisor. Misuse of Visa telephones may result in immediate contract
termination.

Visa equipment and supplies may be used by vendor only when required to work
on-site with secured or proprietary materials or equipment. Personal use of any
Visa equipment, service, or supplies may be considered grounds for immediate
termination of a vendor's engagement.

SCOPE OF COMPANY PARTICIPATION: Vendors will be asked by their project manager
to attend only those meetings which relate to their contracted scope of work or
specific project. Vendors shall not attend corporate, division or department
staff meetings. When in doubt about whether or not participation in meetings is
expected or permitted, the vendor should check with the Visa project supervisor
with whom the vendor is contracting. As a rule, vendors are not included in
company-sponsored holiday or annual celebrations.

Management: The Visa project supervisor is responsible for project management,
as well as evaluation on completed work. In this regard, such supervisor will
give guidance as to the required outcome of the contracted project. It will be
up to the vendor to determine how to accomplish the desired results. If a vendor
provides one of its employees to Visa to complete a contractual arrangement, the
Visa project supervisor may provide project guidance to that employee. However,
it is the vendor Seller's responsibility to handle all issues regarding the
worker's compensation, satisfaction with Visa, assignments, time off, or Visa
personnel interactions.

GIFTS AND GRATUITIES: In order to avoid any activity that could be construed to
unduly influence judgment regarding the use of vendor resources, no gifts,
favors, gratuities, travel, entertainment, meals, or any other item or service
of any value should be offered to Visa employees by the vending Seller or its
employees or contractors.
